Grid Optimization of Tunnel Oxide Passivated Back Contact Silicon Solar Cells

Progress in Photovoltaics: Research and Applications, EarlyView.
The grid pattern design of tunnel oxide passivated back contact silicon solar cells were optimized via device simulation and the estimated cell efficiency was correlated to the required Ag paste consumption. The absolute efficiency gain of zero‐busbar design over pad‐based contact design is more than 0.1%, with increasing advantage when the Ag paste ...

Proteomic Profiling of Primary Hippocampal Neurons Reveals Noncanonical GFAP Expression and Metabolic Adaptations in Glia‐Free Culture

PROTEOMICS, EarlyView.
ABSTRACT Despite their widespread use as a research model, a comprehensive, quantitative proteomic profile of the cultured hippocampal neurons has remained unexplored. Here, we provide the first global proteomic characterization of primary murine hippocampal neurons cultured for 14 days under near‐physiological glucose conditions (2.5 mM).

Enabling Variant Proteogenomic Assay Development Through a Peptide Target Selection Pipeline and Web Application

PROTEOMICS, EarlyView.
ABSTRACT The quantification of key protein variants can guide precision oncology to enable better identification of driver mutations. Bottom‐up assays infer parent protein levels through the quantification of surrogate peptides. Assay methods designed for absolute quantification of protein variants, such as multiple reaction monitoring mass ...

Die GLONASS-Mehrdeutigkeitslösung beim Precise Point Positioning (PPP)

, 2016
Precise Point Positioning (PPP) allows for accurate Global Navigation Satellite System (GNSS) based positioning without the immediate need for observations collected by regional station networks. The fundamental drawback of PPP in comparison to differential techniques such as Real-Time Kinematic (RTK) is a significant increase in convergence time ...

Pesticide exposure of operators during mixing and loading a drone: towards a stratified exposure assessment

Pest Management Science, EarlyView.
Operators are exposed to concentrated formulation during mixing of pesticide into the nurse tank and to an in‐use dilution during loading the drone; stratification of exposure for mixing and loading would inform the exposure assessment approach by applying the appropriate dermal absorption considerations.

Exploratory Analysis of Sustainable Consumption and Production Factors in Services: Insights From Four Case Studies Using Interpretive Structural Modeling

Sustainable Development, EarlyView.
ABSTRACT This study investigates how 14 sustainable consumption and production (SCP) factors interact across four service categories—Mass Service, Professional Service, Service Factory, and Service Shop—using interpretive structural modeling (ISM). ISM enables the identification and hierarchical classification of interdependencies among SCP factors in ...
