Estimating the returns to educational mismatch with panel data: the role of unobserved heterogeneity [PDF]

open access: yes
Using longitudinal data from the Swiss Household Panel, this analysis suggests that the cross-sectional estimates of the returns to educational mismatch are significantly biased when unobserved heterogeneity is omitted in the wage equation.

Effects of Partial Shading Conditions on Maximum Power Points and Mismatch Losses in Silicon-Based Photovoltaic Power Generators

open access: yes, 2019
Photovoltaic (PV) power generators can be used for converting the energy of solar radiation directly into electrical energy without any moving parts. The operation of the generators is highly affected by operating conditions, most importantly irradiances and temperatures of PV cells.

Tamper‐Responsive Physical Unclonable Functions via Graphene‐Interlayered Block Copolymer Random Structures

open access: yesAdvanced Materials, EarlyView.
Self‐invalidating multilayer physical unclonable functions (PUFs) integrate fingerprint‐like metal nanopattern bilayers from block copolymer templates with highly reactive reduced graphene oxide (rGO) interlayers. This tamper‐responsive architecture blocks all unauthorized physical and chemical replication attempts while autonomously deactivating ...
