Precision and Variability in Bacterial Temperature Sensing [PDF]
Biophysical Journal, 2015 In Escherichia coli, the ratio of the two most abundant chemoreceptors, Tar/Tsr, has become the focus of much attention in bacterial taxis studies. This ratio has been shown to change under various growth conditions and to determine the response of the bacteria to the environment.

Fast object detection based on binary deep convolution neural networks
CAAI Transactions on Intelligence Technology, 2018 In this study, a fast object detection algorithm based on binary deep convolution neural networks (CNNs) is proposed. Convolution kernels of different sizes are used to predict classes and bounding boxes of multi-scale objects directly in the last ...

Precision of Flow Sensing by Self-Communicating Cells
Physical Review Letters, 2020 Metastatic cancer cells detect the direction of lymphatic flow by self-communication: they secrete and detect a chemical which, due to the flow, returns to the cell surface anisotropically. The secretion rate is low, meaning detection noise may play an important role, but the sensory precision of this mechanism has not been explored. Here we derive the
