Flexible lithium‐ion batteries: Materials design, interfacial regulation, and strain‐adaptive device architectures

open access: yesFlexMat, EarlyView.
This review highlights recent advances in flexible lithium‐ion batteries for wearable and deformable electronics. It systematically examines deformable electrodes, mechanically compliant gel and solid‐state electrolytes, and strain‐adaptive cell architectures, alongside an analysis of mechano‐electrochemical coupling under dynamic deformation.

Inference for Impulse Responses [PDF]

open access: yes
Poor identification of individual impulse response coefficients does not necessarily mean that an impulse response is imprecisely estimated. This paper introduces a three-pronged approach on how to communicate uncertainty of impulse response estimates ...

Fiscal Cyclicality and Debt Sustainability: Evidence From Over a Century of Data

open access: yesInternational Journal of Finance &Economics, EarlyView.
ABSTRACT Using a historical fiscal dataset for a group of 11 economies over the period 1880–2022, we examine debt sustainability and fiscal policy cyclicality and assess the factors influencing fiscal behaviour. We find that positive and statistically significant responses of primary balances to debt emerge in specific historical episodes and ...

Organic electrochemical transistors for neural recording and modulation: From mixed‐conduction physics to closed‐loop biointerfaces

open access: yesInfoMat, EarlyView.
OECT‐based neural interfaces integrate mixed ionic‐electronic transduction, soft biointegration, multimodal sensing, and closed‐loop modulation, enabling adaptive recording, neurochemical monitoring, and intelligent therapeutic strategies. Abstract Next‐generation neural interfaces increasingly aim to couple neural recording with local processing and ...

Large Datasets for the Euro Area and Its Member Countries and the Dynamic Effects of the Common Monetary Policy

open access: yesJournal of Applied Econometrics, EarlyView.
ABSTRACT We introduce EA‐MD‐QD, a new publicly available dataset comprising 1136 macroeconomic time series for the euro area (EA) and its ten largest member countries observed at monthly or quarterly frequency. Since January 2024, EA‐MD‐QD has been updated monthly and continuously revised, providing a valuable resource for policy analysis in the EA ...

Ultra‐High Frequency Ultrasound Imaging and Quantification of Microvascular Flow in Xenograft Renal Cell Carcinoma in an Avian Chorioallantoic Membrane Model

open access: yesJournal of Ultrasound in Medicine, EarlyView.
Patient‐derived xenograft (PDX) tumor models initiated in avian chorioallantoic membranes (CAM) are under investigation to evaluate the effectiveness of therapeutic options with the objective of personalizing treatments. CAM PDXs paired with ultra‐high frequency ultrasound (UHFUS) imaging could potentially constitute prospective high throughput assays ...

Impact of hamstring versus quadriceps tendon graft on thigh muscle strength and surface electromyography activity after anterior cruciate ligament reconstruction

open access: yesKnee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To compare quadriceps tendon (QT) and hamstring tendon (HT) autografts regarding isometric thigh muscle strength, surface electromyography (sEMG) activity and clinical outcomes following anterior cruciate ligament reconstruction (ACLR).

Ultra‐Fast and Energy‐Efficient PZT Optical Tunable Delay Lines for Programmable Photonic Systems

open access: yesLaser &Photonics Reviews, EarlyView.
Thin‐film PZT enables optical tunable delay lines that simultaneously offer sub‐nanosecond switching, low propagation loss, and zero‐static‐power programmability. A five‐bit on‐chip delay line provides a maximum delay of 387.5 ps with a resolution of 12.5 ps, while reconfigurable MZI splitting ratios further enable non‐volatile optical arbitrary ...
