The role of autophagy in genome stability through suppression of abnormal mitosis under starvation. [PDF]
PLoS Genetics, 2013 The coordination of subcellular processes during adaptation to environmental change is a key feature of biological systems. Starvation of essential nutrients slows cell cycling and ultimately causes G1 arrest, and nitrogen starvation delays G2/M ...

A Novel Dual-Band Six-Phase Voltage-Control Oscillator
Sensors, 2018 The paper presents a novel dual-band six-phase voltage-control oscillator. The voltage-controlled oscillator (VCO) with a single-ended delay cell architecture has a lower power consumption, a smaller chip area, and a larger output swing than one with a ...

Optimal Transport Theory for Cell Association in UAV-Enabled Cellular Networks [PDF]
, 2017 In this paper, a novel framework for delay-optimal cell association in unmanned aerial vehicle (UAV)-enabled cellular networks is proposed. In particular, to minimize the average network delay under any arbitrary spatial distribution of the ground users,

Low-Jitter Clock Multiplication: a Comparioson between PLLs and DLLs [PDF]
, 2002 This paper shows that, for a given power budget, a practical phase-locked loop (PLL)-based clock multiplier generates less jitter than a delay-locked loop (DLL) equivalent. This is due to the fact that the delay cells in a PLL ring-oscillator can consume

Timing of antiretroviral therapy in Cambodian hospital after diagnosis of tuberculosis: impact of revised WHO guidelines [PDF]
, 2012 OBJECTIVE: To determine if implementation of 2010 World Health Organization (WHO) guidelines on antiretroviral therapy (ART) initiation reduced delay from tuberculosis diagnosis to initiation of ART in a Cambodian urban hospital. METHODS: A retrospective

LYMPHOID CELLS IN DELAYED HYPERSENSITIVITY [PDF]
The Journal of Experimental Medicine, 1972 X-irradiation up to 480 R does not inhibit either adoptive transfer of delayed hypersensitivity or production in vitro of soluble mediators, such as migration-inhibitory factor (MIF). Above that dosage and as high as 3000 R, adoptive transfer is inhibited, but production of MIF is not. An increase in skin response occurred when 24–48 hr were allowed to

Delay models for the early embryonic cell cycle oscillator. [PDF]
PLoS ONE, 2018 Time delays are known to play a crucial role in generating biological oscillations. The early embryonic cell cycle in the frog Xenopus laevis is one such example.
