False alarm flighting in avian flocks is common, and has been explained as a maladaptive information cascade. If false per se, then its frequency can only be by it being net adaptive relation to some other benefit or equilibrium. However, I argue that natural selection cannot distinguish between true flights have similar energetic costs, opportunity outcomes. if perceive the difference flightin...

The article presents an analysis of the transformations social role digital communications in context their connection with phenomenon escapism. In this case, escapism is understood not as exclusively negative psychic phenomenon, but inherent need a person to search for novelty. It shown that interaction virtual space Internet has long been regarded cause escapism, since provided opportunity ps...

Experimental evidence of stochastic resonance in an excitable optical system is reported. We apply a sinusoidal forcing to the system and, for a finite external noise level, we find a frequency for which the excitable pulsing occurs periodically at the frequency imposed by the modulation. This resonant frequency matches the inverse of the average escape time of the stochastically driven system ...

The stabilizing effect of quantum fluctuations on the escape process and the relaxation dynamics from a quantum metastable state are investigated. Specifically, the quantum dynamics of a multilevel bistable system coupled to a bosonic Ohmic thermal bath in strong dissipation regime is analyzed. The study is performed by a non-perturbative method based on the real-time path integral approach of ...

Abstract RNA-based therapies have great potential to treat many undruggable human diseases. However, their efficacy, in particular for mRNA, remains hampered by poor cellular delivery and limited endosomal escape. Development optimisation of vectors, such as lipid nanoparticles (LNPs), are impeded screening methods probe the intracellular processing LNPs sufficient detail. We developed a high-t...

A full custom design of a three-stage amplifier is described in this paper. A feedback transconductance stage and a feedforward stage combined with two Miller compensation capacitors are used for frequency compensation. The circuit is designed in 0.18μm CMOS process with a 1.8V supply voltage. When driving a 150pF capacitive load, the amplifier achieves over 100dB dc gain, 2.24MHz gainbandwidth...

This work shows the performance of statistical-based reconstruction techniques when a burst-like packet loss network is used to transmit speech feature vectors on a DSR architecture. Two different approaches to exploit prior information about the speech are outlined. The first models the sequence of quantized vectors through transition probabilities to make estimations based on data-source info...

Mobile Ad hoc Network (MANET) is a collection of wireless mobile nodes that dynamically form a network temporarily without any support of central management. Routing in Mobile ad hoc network is extremely challenging because of its limited bandwidth, battery constraints, routing overhead, asymmetric link, speed, scalability, packet loss and quality of services. The widely accepted existing routi...
