Extracting individual solar cell data from photovoltaic module electroluminescence images and current-voltage curves

Revista Elektrón
Electroluminescence (EL) imaging is explored as a non-destructive method for quality assessment and characterization of solar modules. Here, we demonstrate the acquisition of dark I(V) characteristics for each individual cell within a solar photovoltaic ...

Somatostatin receptor 4 (SSTR4) is a tumor suppressor in cutaneous and head & neck squamous cell carcinomas

Molecular Oncology, EarlyView.
This study identifies somatostatin receptor 4 (Sstr4) as a critical tumor suppressor against skin and head/neck cancers (HNSCC, cSCC, and BCC). The loss of Sstr4 removes a check on cell growth, causing hyperactivation of the MAPK‐ERK signaling pathway (↑).

Using the Injection System as a Sensor to Analyze the State of the Electronic Automotive System

Sensors
This paper presents a novel diagnostic method that employs the fuel injection system as a sensor for monitoring internal combustion engine pressure, analysing series resistance to detect connector degradation, and evaluating needle movement within the ...

Charge-induced series resistance switching in GaAs solar cells

AIP Advances, 2012
We report the observation of an abrupt decrease in the series resistance and a concurrent steep increase in the dark current at a threshold voltage, and subsequent hysteresis in the current-voltage characteristics of GaAs p-n junction solar cells.

NAPRT loss promotes lung tumor initiation and growth through AKT signaling independently of NAD+ biosynthesis

Molecular Oncology, EarlyView.
Loss of NAPRT promotes lung tumor initiation and growth through a noncanonical mechanism, independent of its role in NAD+ biosynthesis. Mechanistically, NAPRT depletion activates the mTORC2‐driven AKT/β‐catenin signaling axis to enhance clonogenic and invasive phenotypes. Furthermore, lung‐specific Naprt deletion significantly increases tumor burden in

Targeting the EpCAM‐AXL axis to overcome drug resistance in lung cancer

Molecular Oncology, EarlyView.
Lung cancer cells often evade therapy by hijacking signaling pathways. We reveal that cleaved EpCAM (sEpCAM) stabilizes the oncogenic protein AXL, driving NF‐κB and STAT3‐mediated chemoresistance. This EpCAM‐AXL axis identifies a high‐risk patient subset with poor prognosis.

On the General Current Dependence of the Distributed Series Resistance of Solar Cells: The Influence of the Base Resistivity

SiliconPV Conference Proceedings
The lumped series resistance Rs of a silicon solar cell isn’t constant but depends on the operating point of the solar cell. For describing the relevant current dependence analytically, only few theories exist that can easily be applied to experiments ...

Optimisation Method for Pre-set Arc Suppression Coil Damping Resistors Enhancing Ground Fault Detection [PDF]

Zhengzhou Daxue xuebao. Gongxue ban
As a key component of pre-set arc suppression coil, the damping resistor is currently configured primarily to suppress series resonance overvoltage and prevent protection maloperation during normal operation.

Molecular characterization of covRS mutations in M1UK Streptococcus pyogenes

FEBS Open Bio, EarlyView.
Group A Streptococcus (GAS) acquires covRS mutations driving a hypervirulent bacterial state, frequently associated with invasive disease‐like necrotizing fasciitis. We demonstrate that the newly emerged M1UK GAS lineage can also acquire these mutations.

Production-Ready Decomposition of Series Resistance Into Lateral and Fixed Components

SiliconPV Conference Proceedings
The series resistance (Rs) of a solar cell is commonly treated as a constant, but this is a very poor approximation: in modern cells, Rs can vary by a factor of 4 depending on illumination, bias voltage, and temperature.
