Subspace Learning Machine (SLM): Methodology and Performance

, 2022
Inspired by the feedforward multilayer perceptron (FF-MLP), decision tree (DT) and extreme learning machine (ELM), a new classification model, called the subspace learning machine (SLM), is proposed in this work.

Autologous minimally manipulated adipose‐derived stromal vascular fraction in knee osteoarthritis: Lasting symptom relief and imaging evidence from a 12‐month prospective study

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To evaluate the safety and efficacy of intra‐articular autologous transplantation of adipose‐derived connective tissue micrografts rich in stromal vascular fraction (CTM‐SVF), obtained using an enzyme‐free system (Hy‐Tissue® SVF) for knee osteoarthritis (OA). Methods Thirty patients (mean age of 53.3 ± 6.4 years) with Kellgren–Lawrence

SLM aided noninvasive imaging through thin scattering layers

, 2019
We propose and demonstrate a new imaging technique to noninvasively see through scattering layers with the aid of a spatial light modulator (SLM). A relay system projects the incoherent light pattern emitting from the scattering layer onto the SLM.

Generating Helical Polymorphic Beams Using Dielectric Metasurfaces

Laser &Photonics Reviews, EarlyView.
Helix‐shaped polymorphic beams are optical fields whose intensity maxima spiral around the propagation axis, enabling particle manipulation through attractive or repulsive forces. Traditionally requiring expensive spatial light modulators, metasurfaces now provide a compact, cost‐effective alternative. This work demonstrates general helical polymorphic

Effects of solution ageing in compressive behaviour of SLM-In718 triply periodic minimal surfaces

This study aims to investigate the effect of heat treatment on the microstructure and mechanical properties of triply periodic minimal surface (TPMS) structures manufactured by selective laser melting (SLM) from Inconel ® alloy 718 (In718).

Dual‐Metasurface‐Integrated Fiber Array for Bidirectional Cylindrical‐Vector‐Beam Multiplexed Communication Using Off‐Axis Spatial Manipulation

Laser &Photonics Reviews, EarlyView.
A dual‐layer metasurface is integrated on a fiber‐array facet to realize compact, plug‐and‐play free‐space optical links with cylindrical vector beam (CVB) space‐division multiplexing. An optimized off‐axis collimation layer steers multiple channels, while a Dammann vortex layer performs polarization–topology conversion for bidirectional CVB (de ...

Environmental Assessment of Meat and Milk Production of Sedentary Dual-Purpose Cattle Farms in Two Vegetation Zones of Benin Using the GLEAM-i Model

Biology and Life Sciences Forum
To comply with new pastoral regulations in Benin, herders are increasingly adopting sedentary cattle systems, which may pose environmental risks if poorly managed. This study assessed greenhouse gas (GHG) emissions from three sedentary cattle farm types:

Wavefront Shaping for Optimal Extinction of Focused Light by Individual Nanoscatterers

Laser &Photonics Reviews, EarlyView.
Wavefront shaping enables near‐complete optical extinction by nanoscatterers separated from a planar reflector. Time‐reversed emission profiles provide optimal illumination conditions, yielding 70% extinction from a single plasmonic nanoparticle and up to 90% from sub‐wavelength nanoparticle clusters, offering a promising route to efficient in‐ and out‐
