Reassessing the Cross‐Sectional Fiscal Multiplier: Evidence From U.S. Defense Procurement, 1966–2019
ABSTRACT This paper revisits the empirical analysis of Nakamura and Steinsson (2014). I reconstructed and extended the original dataset to cover the period 1966–2019, harmonizing two major sources of data: the Defense Contract Action Data System (DCADS) and USAspending.gov. I discuss how to aggregate these contract‐level data to better capture spending

A new organic molecular cathode interlayer is presented built upon the perylene butyl tetraester scaffold. The new molecule incorporates N‐annulation and a functional amine group to control optical, electrochemical and physical properties and delivers excellent solar cell performance. Abstract We report a new amino‐bay‐substituted, N‐annulated perylene

ABSTRACT The raindrop size distribution (DSD) plays an essential role in understanding rain attenuation effects at extremely high frequencies (EHFs). Over 1 year of DSD measurements was taken at different Köppen–Geiger climate classifications within the United States. Optical disdrometers from Thies Clima were used to measure both the size and velocity

Gas exchange and pulmonary stress variations during SCUBA and breath‐hold diving in open seawater
Abstract figure legend Healthy, trained divers were studied before, during and after diving in open seawater with different techniques. SCUBA divers (diving to 15 or 40 m with air; cycling at depth) and breath‐hold divers (BHDs; sled‐assisted dives to 15, 25 or 40 m) underwent underwater and surface arterial blood gas (ABG) sampling.

Nanoassemblies of an Artificial Ferric Enterobactin Analog for Biosensing Enterobacteriaceae
Nanoassemblies of an artificial trisamine‐based Ferric Enterobactin, analogs to natural enterobactin and ferric enterobactin, is reported as molecular recognition receptors for real‐time biosensing. The electrochemical sensors, made from the nanoassemblies of its iron(III)complex, exhibit rapid anodic peak current changes upon exposure to live cells of

Dust‐Induced Losses in Solar Photovoltaic Potential and Their Long‐Term Changes Over North Africa
Abstract North Africa (NA) offers exceptional potential for large‐scale solar photovoltaic (PV) deployment to mitigate climate change. Dust aerosols, however, pose a barrier to PV performance by dimming sunlight dimming effect (DE) and settling on panels soiling effect (SE), yet their relative roles across NA's diverse climate zones remain unclear ...

Anomalous Stiffening of a Conjugated Polymer During Electrochemical Oxidation
The electromechanical response of a thienothiophene‐based conjugated polymer with triethylene glycol side chains is investigated. Electrochemical nanoindentation and atomic force microscopy reveal a modest and reversible increase in elastic modulus at room temperature upon electrochemical oxidation.

Chiral Nanohoops as an Efficient Spin Polarization System
Chiral conjugated nanohoops with a central dibenzopentalene unit exhibit 90% spin polarization at low voltage and high conductivity. These properties make them ideal components in molecular spintronics applications. Abstract A central challenge in molecular spintronics is to achieve a high spin polarization at low operating voltages and ambient ...

Beyond Imperfect Match: Silicon/Graphite Hybrid Anodes for High‐Energy–Density Lithium‐Ion Batteries
Silicon/graphite (Si/Gr) hybrid anodes are limited by Si's large volume change and mismatch with Gr. This review offers mechanistic insights into imperfectly matched Si/Gr hybrid anodes, elucidating heterogeneous lithiation behavior and interfacial failure pathways, and thereby informing the design of durable, high‐energy–density lithium‐ion batteries.

Mushrooms produce enzymes via the radical apparatus to attack lignin and cellulose and we evaluated extracts from byproducts of Pleurotus ostreatus and Agaricus bisporus in terms of content of ligninolytic enzymes and as sustainable means of enhancing the degradability of forages. The extracts contained ligninolytic enzymes and were used to treat wheat
