An accurate common-mode current prediction method for transformerless photovoltaic inverters based on graph theory

, 2017
The common-mode current is an important indicator with transformerless photovoltaic inverters. However, up to now, there is not an accurate method to predict common-mode current in the inverter design process, resulting from inappropriate device ...

Synchronized Electro‐Chromo‐Emissive Devices Using a Mixed Ionic‐Electronic Conductive Layer for XR Applications

Advanced Functional Materials, EarlyView.
A single cell type Electro‐chromo‐emissive (ECECL) device integrating synchronized electrochromic (EC) and electrochemiluminescent (ECL) functions is developed using a mixed ionic‐electronic conductor (MIEC). A MIEC layer reduces ionic/electronic resistance, enabling ultrafast switching and enhanced optical contrast.

Existence of a regular unimodular triangulation of the edge polytopes of finite graphs [PDF]

, 2016
In this paper we give several criteria for the edge polytope of a fundamental FHM-graph to possess a regular unimodular triangulation in terms of some simple data of the the graph. We further apply our criteria to several examples of graphs and show that

Action functional as an early warning indicator in the space of probability measures via Schrödinger bridge [PDF]

Quant. Biol.
Critical transitions and tipping phenomena between two meta‐stable states in stochastic dynamical systems are a scientific issue. In this work, we expand the methodology of identifying the most probable transition pathway between two meta‐stable states ...

Exciton Binding Energy Modulation in 2D Perovskites: A Phenomenological Keldysh Framework

Advanced Functional Materials, EarlyView.
The intrinsic screening effects are successfully decoupled from structural distortion by rigorously designing a series of 2D perovskites. This enabled us to demonstrate how the dielectric environment modulates the quasiparticle bandgap and exciton binding energy.

Symptom network connectivity and interaction among people with HIV in China: secondary analysis based on a cross-sectional survey

BMC Public Health
Background The symptom burden in people with HIV (PWH) is considerable. Nonetheless, the identification of a central symptom, or bridge symptom, among the myriad symptoms experienced by PWH remains unclear.
