    1. Method 1: numpy.any() to check if the NumPy array is empty in Python numpy.any() method is used to test whether any array element along a given axis evaluates to True. Syntax: numpy.any(a, axis = None, out = None, keepdims = <no value>) Parameters: array: Input array whose elements need to be checked.axis: Axis along which array elements are evaluated.out: Output array having the same dimensions as Input arraykeepdmis: If this is set to True, the axes which are reduced are left in the result. Return Value: A new Boolean array (depending on the ‘out;’ parameter) 1234567import numpy as nparr = np.array([])flag = not np.any(arr)if flag:    print('Array is empty')else:    print('Array is not empty') Output: Array is empty In this example, we have used numpy.any() method to check whether the array is empty or not. As the array is empty, the value of the flag variable becomes True, and so the output ‘Array is empty’ is displayed. The limitation to this function is that it does not work if the array contains the value 0 in it.

      This is WRONG.

      numpy.any() checks if there is at least one non-zero element in an array.

    1. The else keyword in a for loop specifies a block of code to be executed when the loop is finished

      This statement is as exact as useless. It doesn't explain the purpose of an else statement in a for loop. The example is even more confusing, because the result is exactly the same with the second print statement without the else.

    1. Celartia’s Petaka (which has a selectively permeable membrane for hypoxic conditions)

      Petaka doesn't use a membrane. This is the case of its predecessor, OptiCell, developed by the same inventor. Petaka has a long air duct that creates O2 and CO2 gradients that provide hypoxia and pH stability.

    1. Filosoft S.A. This small company (9 employees), associated with a Madrid-. based group, IPSA, develops and .markets specialised software for communications and for ·scientific and technical purposes -particularly for laboratories engaged in research and quality control. Filosoft has carried out some projects in collaboration with University researchers. It has won business from a fellow tenant on the Park, SPRITEL (development of communications software) , and hopes to win more from current contacts· with two other tenant organisations. Filosoft also hopes to carry out a collaborative project with one of the Park-based research centres. In due course, it plans to make international contacts (particularly important for the development of new applications) through the management of the Park.

    1. We use itertools.tee here so we don't have to pollute our code with temporary lists.

      But if you consume one of the iterators before starting the other one (as in your case), a temporary storage is created behind the scenes.

      From tee documentation:

      In general, if one iterator uses most or all of the data before another iterator starts, it is faster to use list() instead of tee().

    1. wget https://developer.nvidia.com/compute/cuda/10.0/Prod/local_installers/cuda_10.0.130_410.48_linux

      This may cause a problem with previous installations. Using the deb version of the installer seems easier: https://developer.nvidia.com/cuda-downloads?target_os=Linux&target_arch=x86_64&target_distro=Ubuntu&target_version=1804&target_type=deblocal

    1. el polo norte magnético es un punto muy importante para el funcionamiento de las telecomunicaciones, los sistemas GPS o la navegación aérea

      No. Los polos magnéticos no afectan al GPS. Respecto a la navegación aérea, su efecto es irrelevante, dado el uso mayoritario de sistemas de navegación tradicionales como VOR, ADF, o modernos como el GPS. Y respecto a las telecomunicaciones, el efecto es nulo.

    1. Storage and Delivery of Stem Cells for Cellular Therapies

      Ambient temperature storage provides another option for the preservation and transport of cells for SCTs. This hypothermic approach simplifies the preservation process and greatly reduces cost as well as reliance on specialist equipment such as the dry shippers or liquid nitrogen vessels used in cryopreservation. The literature for ambient temperature preservation is limited compared to cryogenic and chilled techniques, particularly for therapeutically relevant cells such as hMSCs. The main realizations of the technique have included alginate gel entrapment and enclosure in hermetic culture chambers such as the PetakaG3.

    1. Mediumiin asetettu hypok-sia kuitenkin purkautuu varsin nopeasti, mikäli se on kosketuksissa huoneilman kanssa. Näin ollen ilman täydellisesti suljettua systeemiä olosuhteet ovat epästabiilit ja toisaalta suljetun systeemin rakentaminen voi olla vaikeaa sovelluksesta riippuen.

      This is completely wrong!!!

      Google tranlsation:

      However, the hypokia placed in the medium is discharged very quickly if it is in contact with the room air. Thus, without a fully enclosed system, the conditions are unstable and, on the other hand, the construction of a closed system may be difficult depending on the application.

      Petaka G3 maintains hypoxic conditions in the culture medium while in contact with the atmosphere.

    1. there is no unique mapping that definitively converts a wavelength to a colour

      This sentence is wrong. Each light spectrum does determine a specific colour. In particular, a monochromatic light defines a colour. The opposite is not true: the same colour may be created using many different spectra.

    1. We provide results of our method on three challengingbiomedical datasets of bright-field microscopy images ofC.elegans, E.Coli, Hela and the plant phenotyping dataset(CVPPP 2017 sequence A1).

      The E. coli and HeLa datasets are not bright-field images. They are phase-contrast images instead.

    1. Many detection methods such as Faster-RCNN and YOLO, perform badly in small objects detec-tion. With some considerable improvements in the originalframework of YOLOv2, our proposed SO-YOLO can solvethis problem perfectly.



    1. Passaged rBMSCs exhibited significantly greater proliferation rates at 1% O2 and 5% O2 than those at 18% O2 and the cells exposed to 1% O2 showed the highest proliferative potential, which was evidenced by the growth curves, colony-forming efficiencies, and CCK-8 absorbance values.
    1. As a convolutional neural network, SO-YOLO outperforms state-of-the-art detection methods both in accuracy and speed.
    2. SO-YOLO performs well in detecting small objects compared with other methods.
