Electrochromic Adaptive Solar Heater and Sub‐Ambient Passive Daytime Radiative Cooler

open access: yesAdvanced Materials, EarlyView.
An electrochromic Cu–Bi nanocluster device dynamically switches between solar heating and daytime sub‐ambient radiative cooling without mechanical motion. Defect‐activated graphene, minimized electrolyte loss, and pulse‐assisted reversible electrodeposition enable opposite solar and mid‐infrared modulation in one opaque platform, establishing a design ...

Durability of Soft Pneumatic Actuators: A Review and Benchmarking Protocol

open access: yesAdvanced Robotics Research, EarlyView.
Lack of durability is a key challenge hindering the broad scale adoption of soft pneumatic actuators (SPAs) in automation industries. This review provides a comprehensive overview of existing research on SPA durability, introduces a standardized durability benchmarking protocol to consolidate the testing of SPAs, and outlines promising directions for ...

Research of the impact of business cycles on the unemployment in the countries of the European Union

open access: yesMokslas: Lietuvos Ateitis, 2022
This paper examines the impact of business cycles on unemployment rates in EU countries. The relationship between changes in gross domestic product and changes in the unemployment rate is referred to in the academic literature as Okun’s law. This law is

EMPLOYMENT AND THE BUSINESS CYCLE [PDF]

open access: yesThe Manchester School, 2013
This paper investigates the differences in the cyclical dynamics in employment on non‐agricultural payroll (ENAP) and total civilian employment (TCE), and the implications for monitoring US business cycles in real time. We find that employment measures have diverged considerably around the last three recessions and subsequent recoveries.

Stage‐Adaptive Janus Microneedle System for Redox‐Immune Regulation and Mitochondrial Protection in Infected Diabetic Wound Healing

open access: yesAdvanced Science, EarlyView.
ABSTRACT Infected diabetic wounds are sustained by a vicious cycle of hyperglycemia‐driven bacterial infection, persistent oxidative stress, and excessive inflammation, which collectively disrupt the ordered progression of tissue repair. Here, we engineered a stage‐adaptive Janus microneedle patch (MN‐FeSAC‐PPE) to enable a staged therapeutic process ...

Borders and business cycles [PDF]

open access: yesJournal of International Economics, 1999
We document that business cycles of U.S. Census regions are substantially more synchronized than those of European Union countries, both over the past four decades and the past two decades. Data from regions within the four largest European countries confirm the presence of a European border effect—within-country correlations are substantially larger ...

An Embodied Paper‐Based Microfluidic Al‐Air Battery for Enduring Untethered Insect‐Scale Robots

open access: yesAdvanced Science, EarlyView.
This work presents a centimeter‐scale microfluidic aluminum–air battery (MFAAB) with dual‐surface anode and F−‐mediated byproduct decomposition. The design enables a high capacity of 2697.05 mAh/g Al and delivers tens of milliwatts to power LEDs, motors, and a toy car.

Time-heterogeneous impacts of global temperature cycle on world business cycle

open access: yesJournal of Applied Economics
We study the statistical relationship between the world business cycle and the global temperature cycle. To amplify the signal-to-noise ratio, we estimate a two-state latent dynamic process from the original data using the endogenous regime-switching ...

Vacancy‐Driven Ni Exsolution in Prussian Blue Analogues Creates Cooperative Defect–Metal Sites for Alkaline Hydrogen Evolution

open access: yesAdvanced Science, EarlyView.
Multimetal Prussian blue analogues (PBAs) are converted by low‐temperature Ar annealing into a cavity/CN‐vacancy architecture that triggers in situ Ni exsolution, creating dense Ni‐PBA interfacial motifs. These motifs optimize water dissociation and H* adsorption in alkaline media, delivering markedly accelerated HER kinetics and long‐term stability ...
