Fabrication‐Aware Mechanical Design of SLA‐Printed Polymeric Microneedles: Integrating Geometry, Dimensional Fidelity, and Structural Instability

Journal of Applied Polymer Science, EarlyView.
SLA‐printed microneedles exhibit fabrication‐induced dimensional deviations that strongly influence their mechanical response. Comparison of nominal CAD, global as‐printed, and local critical‐section models shows that local tip‐region geometry provides the closest agreement with experimental instability loads, highlighting the importance of fabrication‐

On a degenerate high-order parabolic equation for the evolution of elastic plates

In this paper, we study a degenerate high-order parabolic equation that describes the evolution of elastic plates and thin films and membranes of viscous liquid, in which the surface tension the liquid/air interface determines the dynamics.

Ultrafast RF Spectrum Analyzer Assisted by Optical Short‐Time Fourier Transform

Advanced Physics Research, EarlyView.
We present Recent efforts in an ultrafast RF spectrum analyzer based on the short‐time Fourier transform (STFT) at over 10 MHz frame rate and over 40GHz bandwidth to improve performance and support applications. All these efforts could inspire more innovative applications of temporal imaging modalities in the future.

Morphological adaptations of cervical vertebrae in plunge‐diving sulids

The Anatomical Record, EarlyView.
Abstract Foraging strategy frequently drives morphological diversification in birds. The plunge‐diving behavior of certain species makes the functional and ecological trade‐offs of variation in cervical vertebrae an especially intriguing question. This study compares cervical vertebrae across five plunge‐diving species and two non‐plunge‐diving species,

Principal Component‐Based Classification of Blazar Candidates of Uncertain Type in the 4FGL/LAT

Astronomische Nachrichten, EarlyView.
ABSTRACT We adopted principal component analysis (PCA), linear discriminant analysis (LDA), and support vector machines (SVM), to study classification for a sample of 2708 Fermi blazars: 1142 BL Lac objects (BLLs), 759 flat spectrum radio quasars (FSRQs), and 807 blazar candidates of uncertain type (BCUs).

Metal nanostructure‐coupled label‐free localized surface plasmon resonance biosensors for rapid and sensitive disease diagnosis

BMEMat, EarlyView.
LSPR biosensing enables rapid, sensitive, and low‐sample‐volume detection of biomarkers, with broad applications in diagnosing cancer, infectious, and chronic diseases. Advances in nanostructure design, micro/nanofabrication, and microfluidic integration have expanded the potential of LSPR sensors in biomedical diagnostics.

Journey to Net‐Zero and Investment in Renewable Energy: Evidence From Developed and Developing Countries

Business Strategy and the Environment, EarlyView.
ABSTRACT This study examines how geopolitical risk, high‐technology exports and the Paris Agreement shape investment in renewable energy across developed and developing economies. Drawing on structural contingency theory, we conceptualise renewable energy investment as a country‐level response to external contingencies and analyse a global panel of 100

Analysis of Radial Heat Transfer in Cooled Fixed‐Bed Reactors by One‐ and Two‐Dimensional Models

Chemie Ingenieur Technik, EarlyView.
Exothermic fixed‐bed reactors are analyzed using 1D and 2D models. Radial temperature profiles from the 2D model enable optimization of the 1D approach via adjusted overall heat transfer coefficient. Derived correlations improve prediction accuracy, whereas thermal runaway behavior and model sensitivity are evaluated. ABSTRACT Exothermic reactions in a

Review of CFD modelling techniques for single‐phase and multiphase flow in static mixers

The Canadian Journal of Chemical Engineering, EarlyView.
This review synthesizes computational fluid dynamics (CFD) approaches for static mixers, linking hydrodynamics to pressure drop, particle/droplet distributions, mixing metrics, and heat‐transfer performance to guide modelling choices and design decisions. Abstract Static mixers enable compact and low‐energy intensification.
