From Planar to 3D Nanophotonic Lenses: Advancing Design, Fabrication, and Applications

Laser &Photonics Reviews, EarlyView.
Three‐dimensional nanophotonic lenses are enabled by an integrated workflow that links design parameterization, full‐wave electromagnetic simulation, computational optimization, and freeform fabrication. This Review summarizes how these tools expand optical design freedom beyond a single patterned plane by enriching the local meta‐atom response and ...

MXene‐Based Flexible Memory and Neuromorphic Devices

Small, EarlyView.
The unique two‐dimensional structure, excellent electrical conductivity, and diverse surface groups of MXenes have garnered significant attention. Coupled with their exceptional flexibility, MXene‐based devices hold immense potential for flexible memory and neuromorphic systems. This review comprehensively discusses the fundamentals of flexible devices,

HSPE1 deficiency underlies the crosstalk between metabolic dysfunction‐associated steatotic liver disease and age‐related macular degeneration

VIEW, EarlyView.
Rare‐earth ions act as multifunctional modifiers in perovskite solar cells by improving charge transport, suppressing oxygen vacancies, passivating defects, promoting grain growth, and enabling redox‐mediated stabilization. In addition, RE‐doped layers can expand spectral utilization through upconversion and downconversion, thereby enhancing light ...

Comparative Analysis of Modal Dispersion in Graded-Index Multimode Fibers [PDF]

In this paper, we compare the modal dispersion (MD) in standard and bend-insensitive graded-index multimode fibers (GI-MMFs and BI-MMFs). By selectively exciting 45 modes across 9 mode groups, we observed a maximum differential group delay (between mode ...

Molecular profiling of pediatric medulloblastoma in Kazakhstan: Genomic alterations, subgroup distribution, and survival

Brain Pathology, EarlyView.
A practical formalin‐fixed, paraffin‐embedded (FFPE)‐based molecular workflow integrating pathology, immunohistochemistry, and genomic profiling provides clinically meaningful subgroup classification of pediatric medulloblastoma and expands molecular evidence from an underrepresented Central Asian population. Abstract Medulloblastoma is the most common

Phloroglucinol inhibits human ureteral contractions via activation of cAMP‐PKA pathway

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Phloroglucinol is used to treat renal colic, especially when non‐steroidal anti‐inflammatory drugs are contraindicated. This study aimed to clarify its mechanism by examining effects on human ureteral contractility and underlying signalling pathways. Experimental Approach Urinary levels of neurokinin A (NKA), substance P

Sclerostin regulates bone morphogenetic protein (BMP) bioavailability through interactions with BMP complexes and fibrillin microfibrils

The FEBS Journal, EarlyView.
Sclerostin (SOST) is a multifunctional extracellular modulator of BMP and Wnt signaling. SOST binds with high affinity to fibrillin‐1 and fibrillin‐2, localizing it to fibrillin microfibrils and regulating its extracellular bioavailability. Fibrillin‐bound SOST cannot engage BMP‐7 prodomain (PD) complexes, revealing a competitive mechanism that ...

An Explanation of SRS Beam Cleanup in Graded-index Fibers and the Absence of SRS Beam Cleanup in Step-index Fibers [PDF]

, 2007
Beam cleanup via stimulated Raman scattering in multimode fibers is modeled by numerically considering the competition between the Stokes modes of graded-index and step-index fibers.

Soft Tissue Safety Assessment of Pulsed Solid‐State Thulium:YAG Versus Holmium:YAG Lasers: A Quantitative Porcine Model Simulation

Lasers in Surgery and Medicine, Volume 58, Issue 9, Page 811-820, November 2026.
ABSTRACT Objectives Laser lithotripsy carries an inevitable risk of collateral tissue injury. This study compared the safety profiles of pulsed Holmium:YAG and Thulium:YAG lasers by examining their effects on soft tissue under laser settings relevant to lithotripsy, using ex vivo porcine kidney models.
