Overcoming the Phase Discontinuity Problem in RIS Optimization: A Robust and Scalable Phase‐Aware Deep Regression Framework via Hybrid CNN–LSTM Architecture

Advanced Intelligent Systems, EarlyView.
The phase discontinuity problem—where the cyclic nature of phase angles causes catastrophic errors near the ±π boundary—is a fundamental obstacle in learning‐based reconfigurable intelligent surface (RIS) optimization. A phase‐aware hybrid CNN–LSTM framework resolves this by decomposing phase predictions into sine–cosine components, mapping circular ...

A Numerical Investigation of Film Cooling under the Effects of Different Adverse Pressure Gradients

Aerospace
Film cooling needs to be applied to serpentine nozzles due to an increase in thermal load. Adverse pressure gradients (APGs) near the upper wall of such nozzles hinder the forward flow of the coolant, and they may even induce a recirculation zone that ...

Water Modeling Test for Auxiliary Deslagging by Blowing Gas in Hot Metal Ladle

Teshugang, 2012
Taking the 90 ~ 105 t hot metal ladle at steel works as prototype, a geometric similarity ratio 1： 4 water model is established in laboratory and the effect of hot metal ladle side-blowing gas for auxiliary-deslagging on skimming area is studied by ...

Linear Viscoelastic Behavior of n‐Alkane Diluted Polyethylene Melts: Sorption, Desorption, and Oscillatory Rheometry

Journal of Applied Polymer Science, EarlyView.
This study systematically maps polyolefin dilution dynamics using a homologous series of n‐alkanes. Integrating gravimetric sorption, subsequent controlled desorption, and oscillatory rheometry establishes a precise framework to analyze reduction in viscosity at least for polymer diluent mixtures with polymer concentration > 35% and diluent ...

Process Optimization of Solution Blow Spinning for Poly (N‐Isopropylacrylamide) Fibers

Journal of Applied Polymer Science, EarlyView.
Solution blow spinning has emerged as a safe and scalable technique for fabricating thermoresponsive PNIPAM fibers. The influence of key parameters on jet stability and fiber uniformity is determined through both rheological analysis and statistical process optimization. A Box–Behnken design reveals an optimized window for producing PNIPAM fibers below

Research on performance of a tile vortex generator with enhanced film cooling

Reli fadian
In order to solve the technical problem that the cooling margin of the cylindrical hole is insufficient at low blowing ratios and the cold flow is separated from the wall at high blowing ratios, based on the tip-covered vortex generator (TCVG), a new ...

Loss of Reduction and Clavicle Fractures Commonly Occur in Patients Undergoing Acromioclavicular Joint Reconstruction and Female Sex Is Associated With Higher Fracture Risk

Arthroscopy, Sports Medicine, and Rehabilitation, EarlyView.
Purpose To use a large, multi‐institutional database to characterize the outcomes and complication profile after primary acromioclavicular (AC) joint reconstruction and to evaluate potential sex‐related differences in outcomes and complications. Methods The TriNetX national database was queried for patients undergoing AC joint reconstruction between ...

The Biologically Enhanced Anterior Cruciate Ligament Reconstruction With Combined Injection of Harvested Platelet‐Rich Plasma, Thrombin, and Bone Marrow Aspirate Concentrate

Arthroscopy Techniques, EarlyView.
Abstract Despite continuous advances, anterior cruciate ligament reconstruction still struggles to restore full native knee function, as most techniques improve mechanical stability but overlook biological healing. The described superenhanced anterior cruciate ligament reconstruction technique aims to address this biological problem through a quadruple
