From Food to Power: Hydrogel Thermoelectrics for Ingestible Electronics
Advanced Functional Materials, EarlyView.We introduce a fully edible thermoelectric–electrochromic platform that harvests heat from food and converts it into a visible color change. N‐type and p‐type hydrogel thermoelectric generators connected in series power anthocyanin‐based electrochromic displays, demonstrating the feasibility of safe, biodegradable, ingestible systems for on‐food ...

Principal Portfolios: Recasting the Efficient Frontier [PDF]
A new method of analyzing the efficient portfolio problem under the assumption that short sales are allowed is presented. It is based on the remarkable finding that the original asset set can be reorganized as a set of uncorrelated portfolios, here named

Advanced Functional Materials, EarlyView.This study shows that lizard osteoderm capping tissue is a hyper‐mineralized hydroxyapatite layer consistently covering the superficial osteoderm surface in those species studied here, yet it varies greatly in morphology, nanostructure, and mechanical performance across species.

TECHNICAL EFFICIENCY OF NEW YORK DAIRY FARMS [PDF]
The technical efficiencies of New York dairy farms were estimated using a frontier production function. The average farm was 69 percent efficient. Individual farm efficiency was regressed on variables not considered inputs to explain why a farm was not ...

Advanced Functional Materials, EarlyView.We fabricated a biomimetic dendrimer‐modified thin‐film nanocomposite membrane with a coordination‐assisted ion‐selective interface. pH‐responsive polypeptide sites preferentially bind Mg2+ and promote Li+ permeation, as predicted by density functional theory calculations of metal‐ligand interactions.

Portfolio Performance Gauging in Discrete Time Using a Luenberger Productivity Indicator [PDF]
This paper proposes a pragmatic, discrete time indicator to gauge the performance of portfolios over time. Integrating the shortage function (Luenberger, 1995) into a Luenberger portfolio productivity indicator (Chambers, 2002), this study estimates the ...

Advanced Functional Materials, EarlyView.Solution‐processed OLEDs containing discotic liquid‐crystalline MR‐TADF emitters are reported. Supramolecular self‐assembly induces homeotropic columnar alignment, enforcing preferential horizontal orientation of the emitter transition dipole moment in spin‐coated films, which leads to an enhancement in the device light outcoupling efficiency while ...

Does Higher Cost Inefficiency Imply Higher Profit Inefficiency? - Evidence on Inefficiency and Ownership of German Hospitals [PDF]
This paper investigates cost and profit efficiency of German hospitals. More specifically, it deals with the question how hospital efficiency varies with ownership, patient structure and other exogenous factors, which are neither inputs nor outputs of ...
