Discrete Mathematics, 1974 AbstractA possible way to obtain a complicated graph imbedding in a surface is to derive it as a covering of a simpler imbedding by assigning “voltages” to the edges of the simpler imbedding. Although this new method is but the dual of the current graph construction,it has independent importance in practical applications, illustrated here by a ...

Electrical Treeing of SiR and SiR/Fe3O4 Nanocomposites in High Magnetic Field
IEEE Access, 2023 This paper investigates the effects of high magnetic field on electrical treeing of silicone rubber (SiR). Experimental results show that electrical trees are more easily to be initiated and spread further along the direction of electric field under the ...

Test Strategies for Multi-Voltage Designs [PDF]
, 2009 Reducing the power consumption of digital designs through the use of more than one Vdd value (Multi-Voltage) is known and well practiced. Some manufacturing defects have Vdd-dependency, which implies defects can become active only at certain power supply

Voltage Ripple Reduction in Voltage Loop of Voltage Source Converter
International Journal of Power Electronics and Drive Systems (IJPEDS), 2017 In order to achieve a good dynamical response of a full-bridge AC-DC voltage source converters (VSC). The bandwidth of PI controller must be relatively wide. This leads to the voltage ripple produced in the control signal, as known that its ripple frequency has twice of the line frequency and cause the 3rd harmonic of an input current. A Ripple Voltage

Genetic voltage indicators [PDF]
BMC Biology, 2019 AbstractAs a “holy grail” of neuroscience, optical imaging of membrane potential could enable high resolution measurements of spiking and synaptic activity in neuronal populations. This has been partly achieved using organic voltage-sensitive dyes in vitro, or in invertebrate preparations yet unspecific staining has prevented single-cell resolution ...

Correction of conductance measurements in non-space-clamped structures: 1. Voltage-gated K+ channels [PDF]
, 2003 To understand functions of a single neuron, such as propagation and generation of synaptic or action potentials, a detailed description of the kinetics and distribution of the underlying ionic conductances is essential.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...
