Spatial resolution and gain control are important sensory-system functions that frequently involve lateral inhibition, which can increase spatial tuning of a neuron by effectively reducing the area of its receptive-field center. In the vertebrate retina, lateral inhibition can modulate the direct pathway for light-evoked signals (photoreceptors to bipolar cells to ganglion cells) both via horiz...

An outbreak of COVID-19 cases among food and nutrition department employees at a hospital kitchen occurred because it was difficult to maintain physical spacing between staff. There is lack people during self-isolation. However, the must still operate 24 hours provide meals. This study aimed comprehensively evaluate plate waste, patient satisfaction, associated with cook-serve methods compared ...

The spherical limit of strongly commensurate dirty-bosons is studied perturbatively at weak disorder and numerically at strong disorder in two dimensions (2D). We argue that disorder is not perfectly screened by interactions, and consequently that the ground state in the effective Anderson localisation problem always remains localised. As a result there is only a gapped Mott insulator phase in ...

Homogeneous-charge compression ignition (HCCI) engines have been shown to have higher thermal efficiencies and lower NOx and soot emissions than spark ignition engines. However, HCCI engines experience very large heat release rates which can cause too rapid an increase in pressure. One method of reducing the maximum heat release rate is to introduce thermal inhomogeneities, thereby spreading th...

In the present paper, a numerical study is performed to investigate the response of different plates aluminum alloys subjected to low velocity impact condition. In this regard, the square AA5083-H116 aluminum plates with dimensions 300×300 and 3 mm and 5 mm thick under low velocity impact are modelled, and a mesh convergence study is carried out to decide the appropriate number of elements. In ...
