Evaluation Summary:

The authors report that neurons in V1 and V4 provide multiplex information of simultaneously presented objects. A combination of multi-single unit recordings, statistical modelling of neuronal responses and neuronal correlations analyses argues in favor of their claims. Pairs of neurons having similar object preferences tended to be positively correlated when both objects were presented, while pairs of neurons having different objects preferences tended to be negatively correlated. These patterns and others suggest that information about the two objects is multiplexed in time. There are, however, some unclear points that deserve discussion and further analysis that could more strongly support the claims.

Evaluation Summary:

This paper will be of interest to readers interested ligand-gated ion channels and their evolution. The authors show that ancestral AChR beta subunits reconstructed phylogenetically can form homomeric channels that open spontaneously. The work expands our understanding of agonist-independent AChR gating and highlights intriguing aspects of AChR evolution.

Evaluation Summary:

Replication Factor C (RFC) is known to play a role in both DNA replication and DNA repair by loading a protein clamp called PCNA onto DNA junctions with a 3'-recessed end. The current paper elegantly demonstrates that RFC has a second DNA binding site that recognizes a single strand-double strand DNA with a 5'-recessed junction. The paper reports a series of interesting structures and confirms binding to both short gapped DNA and nicked DNA by RFC, causing local unwinding DNA at the ssDNA/dsDNA junctions. The paper, which is of interest to colleagues studying DNA replication and repair, should be improved through a few clarifications.

Evaluation Summary:

Hart et al show that loss of mitochondrial complex I rescues succinate dehydrogenase deficient (SDH) cells. The experiments are well performed and the phenotype is potentially very interesting to researchers of cancer metabolism. The authors propose that rescue of SDH deficiency by complex I inhibition is caused by an increase in mitochondrial NADH which leads to a restoration of aspartate levels, which in turn rescues proliferation. To support the model, the authors do demonstrate that there are possible correlations of this phenotype to restored aspartate biosynthesis. However, they do not unambiguously establish a mechanism that fully defines how complex I inhibition rescues the proliferation of SDH deficient cells.

Evaluation Summary:

The authors provide novel evidence that semaphorin signaling (SEMA3F) is engaged in the vascular endothelium and smooth muscle to confer atheroprotection. They show that SEMA3F reduces the activity of key enzyme Phosphoinositide 3-kinase to decrease smooth muscle cell proliferation, migration, and phenotype switching, which contributes to atheroprotection. The study has significant translational potential and yields a new therapeutic target.

Evaluation Summary:

Mahalingam et al. report on a new software suite, ASAP, the assembly stitching and alignment pipeline, capable of montaging and aligning serial sections at a speed leading to total time shorter than image acquisition time. The software applies to both electron microscopy and array tomography, and more generally to any data set consisting of collections of 2D images in need of in-section montaging and cross-section registration. The result is a coarsely registered volume, ready for refining with existing software suits such as SEAMLESS by Macrina et al. (2021) towards subsequent processing, such as image segmentation and neuronal arbor reconstruction for cellular connectomics. This paper will be of special interest to researchers within the field of connectomics, but also to the broad class of scientists who perform large-scale microscopy. The establishment of fast, reliable and scalable image alignment software to process the millions of images produced by modern microscopes at the same speed as they are acquired is key to accelerate research in neuroscience and other fields. The key claims of the manuscript are well supported by the data, and the approaches used are thoughtful and rigorous.

Evaluation Summary:

Using mass spectrometry, Crawford et al. identify aspartate aminotransferase 2 (Aat2) as a protein whose polysome-association is increased under oxidative stress in yeast. Aat2 deletion sensitizes yeast to oxidative stress, which is paralleled by an aberrantly elevated integrated stress response, although polysome-association of Aat2 and its effect on oxidative stress response are independent of its aminotransferase activity. This provides evidence that metabolic enzymes may "moonlight" as post-transcriptional regulators. The study will appeal to experts in the fields of biochemistry, genetics, cellular and molecular biology. The presented data mostly support the authors' conclusions, but there are a few technical issues that should be addressed. These include corroborating Aat2:ribosome association and characterizing the effects of non-catalytic Aat2 mutants on the integrated stress response.

Evaluation Summary:

Ivica et al. provide both functional and structural characterization of a relatively unstudied glycine receptor agonist that is structurally in between a full and partial agonist. The combination of cryogenic electron microscopy and electrophysiological approaches allows for complementary structural and functional investigations into the criteria that determine ligand efficacy at the glycine receptor. This manuscript will be of interest to both biophysical and pharmacological investigations of ligand-gated ion channels.

Evaluation Summary:

This paper introduces Neuroscout, a new web-based platform for the analysis of fMRI data with a particular focus on naturalistic stimuli. It describes a new tool that will potentially be of great use to the neuroimaging community, and whose development is already quite mature and has a number of datasets ready to use online. Neuroscout as a tool will be of particular interest to neuroimagers and cognitive neuroscientists, but the conclusions drawn using the tool should be of interest to neuroscientists more broadly.

Evaluation Summary:

A pathogen's generation interval directly affects estimates of its transmissibility (R), and the period of self-isolation or quarantine needed to prevent transmission. This study shows that the unmitigated generation interval of the original variant of SARS-CoV-2 is several days longer than previously estimated and that interventions have substantially decreased the effective generation interval. These findings improve our ability to model counterfactual intervention-free scenarios. Overall technically sound analyses support the conclusions, and extensive sensitivity analyses show that the findings are robust. However, sampling or ascertainment bias in this relatively small pre-intervention dataset or biased inputs could affect the accuracy of the reported estimates.

Evaluation Summary:

This manuscript describes randomly generated small proteins of <50 amino acids that can rescue the growth of an auxotrophic mutant of Escherichia coli. The authors suggest that these proteins function by binding specifically to a regulatory element in the 5' UTR of the his operon RNA, altering RNA structure to increase expression. The study suggests that functional small proteins can evolve de novo and that newly evolved small proteins can function as regulators by binding RNA. This is an exciting idea, but the suggested mechanism involving the binding of the small proteins to RNA requires additional experimental support.

Evaluation Summary:

This interesting study identifies why or how the integrated stress response pathway regulates cell recovery upon proteotoxic stress, which is especially interesting in cancer cells resistant to proteasome inhibitors. The authors conclude that translation initiation of mRNAs encoding microtubule cytoskeleton, centrosome and ATF5 proteins is necessary to recover from proteotoxic stress. This paper will make a strong contribution to the literature.

Evaluation Summary:

Wang et al., present a thorough analysis of specific neuronal lineages in the early larval ventral nervous system with the objective to relate the birth order to circuit connectivity and function. The stated key findings of the work are (1) the identification of sharp temporal cohort divisions for the lineages under investigation, (2) synapse formation between neurons of different lineages and temporal cohorts, and (3) the observation that output neurons in this instance are born prior to input neurons. The study raises the question of to what extent these findings can be generalized.

Evaluation Summary:

This manuscript is one of the first broad epigenetic analyses in lung development and will be of interest to not only lung biologists but also to the field of epithelial developmental biology. Using paired transcriptomic and epigenetic data, they have uncovered a vast repertoire of signaling mechanisms underlying lung development. These findings have opened up the field's opportunities to understand and study novel pathways and have further defined a role for PI3 kinase signaling in lung development.

Clement and colleagues describe and illustrate the endocasts of six Palaeozoic lungfish genera from superb 3D fossil material, which are very informative for the understanding of brain evolution of lungfishes, the extant sister group to land vertebrates. Rendering important anatomical details regarding brain evolution in lungfishes, and sarcopterygians in general, this work will be of broad interest to zoologists, including vertebrate paleontologists and neuroanatomists.

Evaluation Summary:

Giant dsDNA viruses, with genomes in excess of 1Mb that encode more than a thousand genes, were only recently discovered and their study offers new opportunities to understand life's evolved mechanisms. In this manuscript, Villalta and colleagues report results on one of the most complex known viruses, the Mimivirus. Its genome is compacted into magnificent fibers comprising apparently repurposed GMC-type oxidoreductase paralogs assembled as a helical coat around genomic dsDNA. Cryo-EM and cryo-ET image analysis yielded a structural model of the fiber in multiple states. The authors also provide some evidence that additional viral enzymes, including RNA polymerases, exist within the fiber assemblies. Pending the resolution of certain issues that emerged in peer review, the study will be of broad interest to biologists.

Evaluation Summary:

The paper would be of interest to neuroscientists and clinician scientists interested in better understanding the mechanism of deep brain stimulation (DBS) in the treatment of Parkinson's disease. Using a combination of electrical artifact-free calcium imaging and electrical stimulation, it probes the effects of stimulation on the neural dynamics of basal ganglia structures that correlate with motor improvement. The key claims are well supported with a convincing discussion of the caveats of the methods used.

Evaluation Summary:

McGregor et al. establish a new reinforcement learning paradigm for songbirds, where instead of auditory feedback (white noise) they use mild cutaneous electrical stimulation as a reinforcer. Their data shows that this somatosensory stimulus can aversively drive pitch changes of a targeted syllable in similar manners as an auditory stimulus does. They further show that the anterior forebrain pathway (AFP) and dopaminergic projections to the AFP are necessary for this non-auditory vocal learning by electrolytically lesioning the output nucleus of the AFP and by depleting dopaminergic input to Area X. Their analysis is rigorous and their data convincingly show shared mechanisms for vocal reinforcement learning using white noise (auditory) or cutaneous electrical stimulation (non-auditory).

Evaluation Summary:

Aida et al use a combination of novel experimental measurements and data processing to wrangle the complexity of bacterial growth for different media conditions. This study represents a clear example tackling the complexity of biological systems from the condition sides (~13,000 growth curves were measured) influencing the growth of a well-defined single specie of bacterium and with a reasonable first pass at data processing. The findings are ultimately simple (with essentially 3 conditions accounting all variability in the system) and easily interpretable.

Evaluation Summary:

This study provides novel evidence that a dopamine D2 receptor antagonist enhances model-based control of behavior, whereas blocking opioid receptors has no effect on the trade-off between habitual responding and goal-directed planning. These conclusions are based on compelling behavioral and computational modeling data and will be of interest to cognitive neuroscientists and computational psychiatrists.

Evaluation Summary:

In this paper, the authors find a link between the emergence of functional connectivity (FC) and changes in regional Cerebral Blood Flow (rCBF) in human infancy from birth to 24 months of age, which will be of interest to the increasing field investigating how the establishment of the brain's functional organization is linked to neurodevelopmental and psychiatric conditions. The data quality and complementarity are impressive for infants over this developmental period (0-2 years). Most of the key claims of the manuscript are well supported by the data. However, the relatively sparse sample and cross-sectional nature does limit interpretation.

Evaluation Summary:

This manuscript will be of interest to developmental biologists and pediatric cardiologists. Addressing the role of NR2F transcription factors in the fish heart, it provides novel insight into atrial chamber patterning and the formation of pacemaker cells. High-quality data are presented supporting the novel finding of a requirement of nr2f1a for restricting the production of pacemaker cells. Yet, data are currently not conclusive in claiming transdifferentiation of atrial cells in the mutants.

Evaluation Summary:

This is an interesting report using computational tools and large amounts of prospective samples from clinical trials to identify different signatures. Using data collected early in the infection in outpatients, the authors aim to identify a set of plasma proteins that can predict a number of outcomes, including disease progression, control of viral shedding, and the onset of antibodies during COVID-19. This study adds to the understanding of the host immune response against COVID-19, as well as the potential of computational tools for the molecular taxonomy of immune responses.

Evaluation Summary:

Bistable visual perception offers a unique window to study how perception arises and changes via an interaction between bottom-up and top-down processes. In three Magnetoencephalography (MEG) experiments with advanced neural state space analysis, this study demonstrates that two key aspects of bistable visual perception - perceptual content and perceptual stability - are mediated by slow cortical potential (SCP) and alpha-beta-band neural oscillations, respectively. The findings would be interesting for many fields, such as perception, consciousness, and attention.

Evaluation Summary:

This is a well-designed study that will be of interest to cognitive neuroscientists studying event perception and memory, particularly those interested in naturalistic paradigms. The main contribution is in growing our understanding of how interpretational differences of events are reflected in differences in neural representations of those events. While the presented results are convincing, it remains somewhat unclear what processes drive the observed effects, and thus what the role of the implicated brain regions is in memory updating.

Evaluation Summary:

This manuscript presents a combination of in vivo recording and optogenetic experiments that together with modeling brings a significant message: inhibition is functionally present in the newborn frontal cortex having major effects in EEG dynamics. The work challenges the view on the switch in GABAergic excitation to inhibition and extends phenomenological observations to human infant EEG data.

Evaluation Summary:

This paper combines evolution experiments with genomic analysis of environmental samples to study the evolution of colistin resistance in E. coli. It highlights the importance of pre-existing genomic variations in clinical strains in driving the evolution of antibiotic resistance. The results presented here are relevant for clinical and non-clinical microbiologists studying antibiotic resistance to last-resort drugs like colistin. The design of the research is simple and elegant, and the genomic data analysis connects the in vitro findings to the real world. However, the authors could better align the experimental and clinical data, and better clarify their experimental design choices.

Evaluation Summary:

Vaccines are a major influenza control strategy in swine, but perform sub-optimally and are under-utilized. The manuscript describes a detailed genetic characterization of influenza virus variants in vaccinated versus unvaccinated pigs. The results indicate that viral reassortment, which is an important process yielding new strange of importance to man and animals, may be less common in pigs that have been vaccinated against influenza.

Evaluation Summary:

This is a systematic review by meta-analysis about the effect of calcium supplementation on bone health in people under 35 years old. The authors found that calcium supplementation can significantly improve BMD and BMC in young people. Moreover, a better effect of calcium supplementation was shown in people who are at the plateau of their PBM. A unique feature of this study is that it focused on people at the age before achieving PBM or age at the plateau of PBM, which is different from previous studies that mainly focused on the elderly or children.

Evaluation Summary:

This paper describes a new dotplot-based approach for analyzing Low Complexity Regions (LCRs) in proteins. The work is validated against a single protein, compared to existing methods, and applied to the proteomes of several model systems. The work aims to show links between specific LCRs and biological function and subcellular location, and study conservation in LCRs amongst higher species.

Evaluation Summary:

The manuscript reports results of a combined experimental and numerical investigation of magnetotactic bacteria in strong spatial confinement and under the influence of an external magnetic field. Single cells are trapped in micrometer-sized microfluidic chambers. A variety of trajectories are found, which depend on the chamber size and the strength of the magnetic field. A detailed understanding of swimming in simple controlled confinement is essential to predict the behavior of motile microorganisms in the complex environments of their natural habitat.

Evaluation Summary:

This work offers a simple explanation to a fundamental question in cell biology: what dictates the volume of a cell and of its nucleus, focusing on yeast cells. The central message is that all this can be explained by an osmotic equilibrium, using the classical Van't Hoff's Law. The novelty resides in an effort to provide actual numbers experimentally.

Evaluation Summary:

This manuscript by Kosillo and colleagues presents a series of carefully carried out experiments evaluating the impact of perturbing the mTORC1 and mTORC2 protein complexes selectively in mouse dopamine neurons. By utilizing dopamine neuron-specific Raptor and Rictor cKO mice, this paper elucidated which of these mTOR complexes are responsible for the regulation of dopamine neuronal functions, revealing the importance of mTORC1/2 signaling for the structure and function of dopamine neurons. This paper provided comprehensive data including structural, physiological, and biochemical alterations by genetic deletion of Raptor/Rictor in dopamine neurons.

Evaluation Summary:

This paper is of broad interest to researchers studying chromosome structure. Using a powerful reconstitution system, the authors dissect the function of the chromosome organising complex, condensin II. Several findings, if supported by some additional analyses, are surprising and thus have the potential to fuel further mechanistic studies of condensin function.

Evaluation Summary:

This study describes the correlations between different membrane properties and the size of the soma of spinal alpha-motoneurons (MNs) using data from 40 experimental in vivo studies. The authors have distilled decades of research on motoneuron properties into a set of mathematical relationships that can guide both experimentalists and modelers interested in developing realistic models of populations of motoneurons. The key result is a complete table of the empirical relationships between the anatomical and physiological properties of MNs. Overall, the dataset approach is interesting, although a detailed analysis of the variability within and between datasets is urgently needed. In addition, a simpler framing of the paper could make the main message easier to grasp.

Evaluation Summary:

Kang et al. studied the role of cystathionine beta-synthase , an enzyme involved in homocysteine catabolism, in the senescent state imposed by oncogenic Akt. They find that this enzyme facilitates the acquisition of features of senescence, and is frequently silenced in tumors, whereas re-expressing it reduces cell proliferation. This manuscript is potentially of interest to cancer biologists, particularly those studying oncogene-induced senescence and mechanisms of senescence escape in cancers.

Evaluation Summary:

This work seeks to resolve questions surrounding "unexplained variability in functional recovery" after experimental spinal cord injury in mice using virus-based retrograde tracing from cervical, thoracic and lumbar spinal cord injection sites, tissue clearing and cutting-edge imaging, to develop a supraspinal connectome or map of neurons in the brain that project to the spinal cord. They apply their methods to understand the differences in the connections between the brain and the cervical or lumbar spinal cord and to compare the connectome from intact mice to those of mice with mild, moderate and severe spinal cord injuries. This work will be of interest to neuroscientists interested in tissue clearing, viral labelling, and its applications to spinal cord injury.

Evaluation Summary:

This paper very nicely tackles a methodological problem in aligning different types of datasets (EM and light microscopy) to image embryonic nervous system development in the nematode C.elegans. The paper is important not just from a methodological standpoint, but also provides novel insights into nervous system development that will be of general interest to the reader. The latter deserves more attention in the manuscript.

Guimaraes et al address the origin of the macrophage increase in sensory ganglia after peripheral nerve injury. The authors show that there is no major influx by blood-derived monocytes into ganglia after injury and that resident macrophages proliferate, which is dependent on CX3CR1 signaling. Overall the work is clear and sound and should be of interest to immunologists and neurobiologists.

Evaluation Summary:

The paper provides information about the relative importance of the type I and type III interferon-driven gene expression and anti-viral responses, particularly focused on the role of the Intestinal microbiota to maintain background levels of type III (interferon lambda) signaling. Type III-driven gene expression is highly discontinuous in the epithelial layer and mainly at the villous tips with consequent effects on the kinetics of rotavirus model infections.

Evaluation Summary:

The mechanisms that control cholesterol movement from the plasma membrane (PM) to the endoplasmic reticulum (ER) remain poorly understood. Here, Ogasawara and Ueda propose an intriguing mechanism whereby ABCA1, a membrane protein, moves cholesterol from the inner to the outer leaflet of the PM to keep the cholesterol away from intracellular Aster proteins that move cholesterol to the ER. When cholesterol builds up beyond a threshold, it accumulates on the inner leaflet and is transported to ER by Asters. If strengthened by the analysis of the endogenous ABCA1 and more physiological cholesterol manipulation, this work will be of significant interest to scientists studying lipid metabolism and transport.

Evaluation Summary:

Eckstein and colleagues take a within-participant approach to answer two critical questions in the field of human reinforcement learning: to what extent do estimated computational model parameters generalize across different tasks and can their meaning be interpreted in the same way in different task contexts? The authors find that inferred parameters show moderate to little generalizability across tasks, and that their interpretation strongly depends on task context. Support for these claims could be further strengthened through additional simulations and by providing greater methodological detail.

Evaluation Summary:

This manuscript will be of interest to cell and developmental biologists and neuroscientists. It addresses the question of how the number of connecting neurons in a circuit is matched whilst maintaining topography. It shows that non-autonomous control of neuronal number involves a relay mechanism through two distinct glial cell types, enabling the specification of distinct neuronal classes.

Evaluation Summary:

In this elegant genetic study, Bailon-Zambrano and colleagues draw on classical genetic concepts to address the clinically pertinent question of how genetic variants in the same gene can yield wildly different phenotypes in different individuals. From their case study they conclude that a major contributor is variation in paralog expression. The question addressed is of great interest to evolutionary and developmental biologists in general and to those studying the evolution of developmental mechanisms in particular.

Evaluation Summary:

Beginning with transcriptome data, Rhodes et al. identify a new family of peptides with signalling function called CTNIP in the model plant Arabidopsis thaliana. They use an elegant biochemical capture approach to pinpoint the SERK-dependent LRR receptor kinase HSL3 as the only receptor for these peptides. They provide convincing genetic and biochemical evidence that HSL3 binds CTNIP and that CTNIP perception triggers HSL3-dependent cytoplasmic calcium influx, ROS production and transcriptional changes. Furthermore, they provide initial evidence that the CTNIP-HSL3 module may participate in regulating root growth.

Evaluation Summary:

Wang and colleagues report that the expression of Piezo1 (an ion channel and mechanical sensor) is upregulated on dendritic cells (DC) under conditions of inflammation/high environmental stiffness resulting in DC activation, maturation, and skewing in DC functional polarity and metabolism. They show that Piezo1 knockout results in faster tumor progression and accumulation of more regulatory T cells, and that Smad3 and STAT4 are involved in DC-mediated differentiation of Th1 and Treg. Overall this represents a mechanistic advance in our understanding of DC biology as it relates to cancer and other human pathologies.

Evaluation Summary:

This is a useful study employing a well-established one-pawed reaching/grasping paradigm for fine-motor skill learning to assess if learning is associated with cortical structural changes as assessed by longitudinal MRI measurements in mice. The authors report a non-linear time course of MRI signal changes representing a decrease in grey matter and an increase in white matter volumes in the cerebral cortex and other regions. The authors ascribe these changes to increased myelination, a conclusion that is supported by quantitative immunolabelling for the myelin protein MBP. These results represent an interesting addition to the literature around myelination changes associated with learning/activity (adaptive myelination). Additional histological analysis of changes in myelination would bolster support for the authors' conclusions.

Evaluation Summary:

Cuticles are specialized extracellular matrices that cover the bodies of ecdysozoans, which make up 85% of all animals. How cuticles are formed is very poorly understood, in particular in light of the fact that cuticles are shed and regrown as animals grow. The authors present a comprehensively and carefully curated resource of the components of the pharyngeal cuticle of C. elegans and provide a spatio-temporal framework to understand cuticle assembly. In doing so, the authors propose a function for a large class of intrinsically disordered proteins (IDPs). The significance of this work is high because our understanding of both cuticle formation and of IDPs is poor.

Evaluation Summary:

This manuscript reports a striking finding, which should be of interest to cell biologists and biophysicists. The authors use an innovative approach to recruit clathrin to mitochondrial membranes and observe the budding and fission of clathrin-coated vesicles. The study leads to a much clearer view of how the clathrin lattice functions in endocytosis.

Evaluation Summary:

The authors investigated the structure of phosphoribosyl pyrophosphate (PRPP) synthase (PRPPS) from Escherichia coli, a highly conserved enzyme from bacteria to mammals that catalyzes the synthesis of a key common compound for several metabolic pathways. Combining structural data with mutagenesis and activity assays, they demonstrate that the enzyme is regulated differently by allosteric effectors when assembled into one filament form or the other. The strength of the manuscript is the high-quality cryo-EM data, which allows the reconstruction of two different filament forms bound to different ligands.

Evaluation Summary:

This paper uses an impressively rich dataset (obtained and curated by the authors) to compare the structural brain connectomes of many animals spanning 6 taxonomic orders. The approach is innovative and relies on graph theoretical measures to describe the connectivity, which means it can be done without the need to spatially/functionally match the brains. The authors find that there is more variability between than within order. They attribute this effect to changes in local connectivity features, whereas global patterns are preserved. The approach can potentially be a useful way to study phylogeny and brain evolution.

Evaluation Summary:

The study shows that the LXRbeta - NCOR1 axis restricts the terminal differentiation of Treg cells into effector Tregs. It also suggests that, in addition to an impact on effector Treg differentiation, loss of NCOR1 leads to impaired suppression function in Treg cells. The results may contribute to our understanding of Treg cell differentiation and function.

Evaluation Summary:

There are various ways in which self-fertility has arisen in the fungal kingdom. This study describes a novel form of self-fertility that evolved in a species closely related to the Cryptococcus species causing serious human lung disease, in which sexual development is achieved by self signaling of a cognate pheromone and pheromone receptor pair. Through a combination of high-quality genomic analysis and experimental gene expression and manipulation work, the study adds to our understanding of the evolution and flexibility of fungal breeding systems. This work will be of interest to colleagues studying fungi as well as mating systems in any eukaryote.

Evaluation Summary:

The authors present a study on the cohesion maintenance of E.coli during collective migration in a self-generated gradient. They performed experiments and complemented the study with a predictive model and simulation to understand how bacteria with different phenotype are able to move as a cohesive group and how the individual bacterium defines its own position within the group. Particularly interesting aspects of the study are the use of titration of behavior with chemoreceptor abundance and the use of potential wells to model the attraction of bacteria to the center of their cohesive group. This approach will be of interest to physicists and biologists interested in collective motility and migration.

Evaluation Summary:

In the present study Pal and colleagues provide evidence that hydrogen sulfide (H2S) inhibits HIV replication and reactivation by a variety of mechanisms including inhibition of NF-kB and and recruitment of the epigenetic silencer, YY1, to the HIV promoter. They further report that H2S helps to maintaining mitochondrial bioenergetics and redox homeostasis and suggest that inclusion of an H2S donor in current ART regimens may help to achieve a functional HIV-1 cure.

Evaluation Summary:

This paper will be of interest to scientists who use imaging approaches to study cellular metabolism. It presents a new coarse-grained model for inferring mitochondrial NADH oxidation from NAD(P)H fluorescence lifetime imaging in mouse oocytes. The modeling is thoughtfully and clearly presented, but the validity of some key assumptions of the model and the overall generalizability of the method to other cell types could be strengthened.

Sum: The term in itself may be indeed not the best to describe what corporate social responsibility actually accounts for, and thus a change to human social responsibility would be better placed because of what CSR actually encompasses.

Very good, pithy summary. Worth 100 words.

The first half was good enough. But the addition of "and data become available to other DBMS clients" makes it real-world and makes it clear why it (the first part) even matters.

A "requires clause" is a precondition declaring the sub-set of input values that are not restricted by the type on which the function is defined (e.g. x >= 0, if x : int)

The "return clause" is a postcondition declaring what is the result of the function; including domain-specific properties of the result (e.g. accuracy of approximative operations).

This article focuses on the concept of "mental" and what exactly mental disorders are. This can be considered habits that become reflexes or something that is learned or even a condition that is not "outgrown" from childhood. Not all reactions are voluntary and the idea of the "mind" can not be boiled down to a single explanation since the science is continually changing. Terminology is not understood across the board because scientist, especially across different fields, cannot agree on a single definition. Because habits can be learned though training, there is a possibly for them to be unlearned over a period of time - this is where the importance of a therapist, psychiatrist, counsoler, or psychopathologist comes into paly.

Planners considering social equity, the economy and nature in sustainable development plans have the opportunity to add other dimensions to the mix.

Prior to Campbell and the sustainable development paradigm, planning was about improving sanitation and improving determinants of health in communities.

Article examines Campbell's seminal article's affect on research paradigms on planning and notes that the planners as well as planning researchers have a long way to go in order to put into balance the triad of social, economic, and ecological concerns in order to achieve true sustainable development.

Path parameters:

• Identify a resource uniquely

Request body:

• Send and receive data via the REST API, often specifically to upload data.
• Needs to adhere to REST API principles to be RESTful. Therefore for POST/PUT, needs to send the whole resource in the body.

Query:

• Mainly used for filtering. If you send a query asking for a large number of resources, use query parameters to filter the set of resources that you want. Example: You send a request to api/pictures/category/cat. You will now get all pictures with cats which could be millions. You can put in the query more specific parameters to clarify your request, such as: api/pictures/category/cat?color=black&breed=korat. Now you will get the subset of pictures of cats which havethe color black and are korat cats.

1. we train enough to get to a good area in the loss function.
2. We have a high learning rate(but not too high) so we can explore our surroundings and stumble upon nearby high performing minima. We periodically save the weights(every x epochs)
3. We average the weights . As a result, the averaged weights will be centered around the loss. See left picture below
