On the optimal recovery threshold of coded matrix multiplication [PDF]

Allerton Conference on Communication, Control, and Computing, 2017
We provide novel coded computation strategies for distributed matrix-matrix products that outperform the recent “Polynomial code” constructions in recovery threshold, i.e., the required number of successful workers.

Spatial Distribution and Development of Sequential Sampling Plans for Diaphorina citri Kuwayama (Hemiptera: Liviidae)

Agronomy, 2021
Vector control in huanglongbing management has been conducted on a calendar basis resulting in high production costs. We addressed this issue and proposed a sequential sampling plan to support decision making for intervention against Diaphorina citri ...

T160‐phosphorylated CDK2 defines threshold for HGF‐dependent proliferation in primary hepatocytes

Molecular Systems Biology, 2015
Liver regeneration is a tightly controlled process mainly achieved by proliferation of usually quiescent hepatocytes. The specific molecular mechanisms ensuring cell division only in response to proliferative signals such as hepatocyte growth factor (HGF)

Low-threshold amplified spontaneous emission and lasing from colloidal nanocrystals of caesium lead halide perovskites

Nature Communications, 2015
Metal halide semiconductors with perovskite crystal structures have recently emerged as highly promising optoelectronic materials. Despite the recent surge of reports on microcrystalline, thin-film and bulk single-crystalline metal halides, very little ...

Thresholds and mechanisms of human magnetophosphene perception induced by low frequency sinusoidal magnetic fields

Brain Stimulation
Background: Virtually everyone is exposed to power-frequency MF (50/60 Hz), inducing in our body electric fields and currents, potentially modulating brain function.

The shape of the contact–density function matters when modelling parasite transmission in fluctuating populations [PDF]

Royal Society Open Science, 2017
Models of disease transmission in a population with changing densities must assume a relation between infectious contacts and density. Typically, a choice is made between a constant (frequency-dependence) and a linear (density-dependence) contact–density

A synaptic threshold mechanism for computing escape decisions

Nature, 2018
Escaping from imminent danger is an instinctive behaviour that is fundamental for survival, and requires the classification of sensory stimuli as harmless or threatening. The absence of threat enables animals to forage for essential resources, but as the
