Analysis of Internally Bandlimited Multistage Cubic-Term Generators for RF Receivers [PDF]

open access: yes, 2009
Adaptive feedforward error cancellation applied to correct distortion arising from third-order nonlinearities in RF receivers requires low-noise low-power reference cubic nonidealities.

Generalized magnetoelectronic circuit theory and spin relaxation at interfaces in magnetic multilayers

open access: yesPhysical Review B, 2020
Spin transport at metallic interfaces is an essential ingredient of various spintronic device concepts, such as giant magnetoresistance, spin-transfer torque, and spin pumping. Spin-orbit coupling plays an important role in many such devices. In particular, spin current is partially absorbed at the interface due to spin-orbit coupling.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

A Human Powered Micro-generator for Charging Electronic Devices [PDF]

open access: yes, 2018
A hand-pulled generator has been designed and tested. A preliminary result has been obtained and discussed. This device was created to provide outlet-free charging. Electronic devices are useful when going out into the wilderness. A portable power supply

Memristive Sisyphus circuit for clock signal generation

open access: yes, 2016
Frequency generators are widely used in electronics. Here, we report the design and experimental realization of a memristive frequency generator employing a unique combination of only digital logic gates, a single-supply voltage and a realistic threshold-

Network divergence analysis identifies adaptive gene modules and two orthogonal vulnerability axes in pancreatic cancer

open access: yesMolecular Oncology, EarlyView.
Tumors contain diverse cellular states whose behavior is shaped by context‐dependent gene coordination. By comparing gene–gene relationships across biological contexts, we identify adaptive transcriptional modules that reorganize into distinct vulnerability axes.

Simple extractors via constructions of cryptographic pseudo-random generators

open access: yes, 2005
Trevisan has shown that constructions of pseudo-random generators from hard functions (the Nisan-Wigderson approach) also produce extractors. We show that constructions of pseudo-random generators from one-way permutations (the Blum-Micali-Yao approach ...

A Fully Differential Digital CMOS Pulse UWB Generator [PDF]

open access: yes, 2009
A new fully-digital CMOS pulse generator for impulse-radio Ultra-Wide-Band (UWB) systems is presented. First, the shape of the pulse which best fits the FCC regulation in the 3.1-5 GHz sub-band of the entire 3.1-10.6 GHz UWB bandwidth is derived and ...

On mathematical model and equivalent circuit of transformer (critical analysis of generally accepted theory)

open access: yesVestnik of Astrakhan State Technical University. Series: Marine engineering and technologies, 2023
The article considers the importance of studying the mathematical model and equivalent circuit of the transformer due to the fact that transformers are the most important link in any electric power system, including control and operation systems for marine fishing and transport vessels and stationary marine technological complexes.
