A flexible dual‐gate thin‐film transistor‐based tactile sensor array with polarity‐aware encoding for neuromorphic recognition

FlexMat, EarlyView.
A flexible piezoelectric tactile sensor array is developed by integrating polyvinylidene fluoride sensing elements with dual‐gate indium‐tin‐zinc oxide thin‐film transistor‐based pixel amplifiers. Direct coupling to the high‐impedance gate minimizes signal loss, enabling twofold voltage amplification and an extended effective relaxation time of ∼4.86 s

Forecasting Duration in High‐Frequency Financial Data Using a Self‐Exciting Flexible Residual Point Process

Journal of Forecasting, EarlyView.
ABSTRACT This paper presents a method for forecasting limit order book durations using a self‐exciting flexible residual point process. High‐frequency events in modern exchanges exhibit heavy‐tailed interarrival times, posing a significant challenge for accurate prediction.

The Unintended Consequences of Sugar‐Sweetened Beverage Taxes on Sales and Prices of Beer Beverages

Health Economics, EarlyView.
ABSTRACT This paper estimates the causal effect of Berkeley's sugar‐sweetened beverage (SSB) tax on beer purchases and prices using retail scanner data from 2014 to 2015. Applying both synthetic control and difference‐in‐differences (DID) approaches, we find that the tax reduced beer purchases within Berkeley by 8.9%, while having a negligible effect ...

Deniers and Compliers: Unpacking the Heterogeneous Effectiveness of U.S. Stay‐at‐Home Mandates During the COVID‐19 Pandemic

Journal of Applied Econometrics, EarlyView.
ABSTRACT While existing work shows COVID‐19 stay‐at‐home (SAH) policies decreased mobility on average, we lack evidence regarding heterogeneity in policy effectiveness across US counties. To uncover potential heterogeneity, we implement a novel two‐stage approach.

Development of a Machine Learning Algorithm for Differential Diagnosis Between Primary Immune Thrombocytopenia and Connective Tissue Disease‐Related Thrombocytopenia in Pediatric Patients

Journal of Clinical Laboratory Analysis, EarlyView.
Primary immune thrombocytopenia (ITP) and connective tissue disease‐related thrombocytopenia (CTD‐TP) share overlapping initial presentations in children, often leading to delayed diagnosis and suboptimal management. While existing literature focuses on therapeutic strategies, this study is the first to develop a machine learning (ML)‐based diagnostic ...

Diaphragm Ultrasonography Reveals Progressive Changes in Diaphragmatic Function, Morphology, and Muscle Trophism During Invasive Mechanical Ventilation in Children

Journal of Clinical Ultrasound, EarlyView.
Diaphragm ultrasonography detected progressive structural and functional deterioration in mechanically ventilated children. Prolonged invasive mechanical ventilation and neuromuscular blocking agent use were associated with ventilator‐induced diaphragmatic dysfunction, highlighting ultrasound as a valuable bedside tool to support individualized ...

Point‐Of‐Care Ultrasound for the Assessment of the Cerebroplacental Ratio in Near‐Term Pregnancies: An Agreement Study With Conventional Ultrasound

Journal of Clinical Ultrasound, EarlyView.
In 80 singleton pregnancies at term, handheld point‐of‐care ultrasound (POCUS) was compared with conventional ultrasound for fetal Doppler assessment. Umbilical artery PI, middle cerebral artery PI, and cerebroplacental ratio showed agreement between devices. Between‐device variability was comparable to intra‐observer repeatability, supporting handheld
