Investigation on Periodically Surface-Corrugated Long-Period Gratings Inscribed on Photonic Crystal Fibers

Nanoscale Research Letters, 2017
Transmission characteristics of periodically surface-corrugated long-period gratings (LPGs) inscribed on photonic crystal fibers (PCFs) using a wet-etching technique were experimentally investigated.

A Step‐Up Underwater Endoscopic Mucosal Resection Strategy with Rescue Underwater Injection Endoscopic Mucosal Resection for Non‐Pedunculated Colorectal Lesions

DEN Open, Volume 7, Issue 1, April 2027.
ABSTRACT Objectives Underwater endoscopic mucosal resection (UEMR) is an established treatment for non‐pedunculated colorectal lesions, but securing an adequate resection margin can be difficult in selected cases due to poor visualization or snare instability.

PCF without choice

, 2005
We mainly investigate model of set theory with restricted choice, e.g., ZF + DC + "the family of countable subsets of lambda is well ordered for every lambda" (really local version for a given lambda). In this frame much of pcf theory can be generalized. E.g., there is a class of regular cardinals, and we can prove cardinal inequality.

Association of Preoperative Cognitive Impairment with Poor Outcomes following Transforaminal Lumbar Spinal Fusion Surgery

Formosan Journal of Musculoskeletal Disorders
Background: Preoperative cognitive function (PCF) is gaining attention as a predictor of surgical outcomes due to its association with muscle function and recovery. Its role in postoperative recovery following transforaminal lumbar interbody fusion (TLIF)

Simulation‐Informed Evaluation of Microvascular Parameter Mapping for Diffusion MR Imaging of Solid Tumours

Magnetic Resonance in Medicine, Volume 96, Issue 1, Page 387-402, July 2026.
ABSTRACT Purpose We aim to inform the design of new diffusion MRI (dMRI) approaches for microvasculature quantification that enhance the biological specificity of imaging towards cancer. Methods We adopted simulation‐informed modelling of the vascular dMRI signal. We synthesised signals from 1500 synthetic vascular networks, for a variety of protocols (

PCF theory: applications

, 1998
We deal with several pcf problems; we characterize another version of exponentiation: number of kappa-branches in a tree with lambda nodes, deal with existence of independent sets in stable theories, possible cardinality of ultraproduct, the depth of ultraproducts of Boolean Algebras. Also we give cardinal invariant for each lambda with pcf restriction

Evaluating putative lncRNA‐mediated ceRNA regulatory network involving miR396 and miR319 in maize leaf growth under Fusarium verticillioides infection

Annals of Applied Biology, Volume 189, Issue 1, July 2026.
The final leaf length of maize (Zea mays) was reduced due to the pathogenic fungus Fusarium verticillioides infection as a result of increased expression of miR396 in the elongation zone and decreased expression of miR319 in the mature zone of maize leaves, leading to antagonistic regulation of the expression of the GRF15 and TCP38, respectively ...

A finite element characterization of a commercial endlessly single-mode photonic crystal fiber: is it really single mode? [PDF]

, 2007
One of interesting properties of photonic crystal fibers (PCFs) is their possibility to be single-moded over a wide wavelength range, down to UV, while still having a reasonably large modal profile.

Quantification and Clinical Correlation of Posterior Cranial Fossa Cerebrospinal Fluid Volume in Primary Hemifacial Spasm Using Magnetic Resonance Imaging

Annals of Indian Academy of Neurology
Background and Objective: Primary hemifacial spasm (HFS) is caused by neurovascular conflict (NVC) at the root entry zone of the facial nerve. Whether reduction of posterior cranial fossa (PCF) cerebrospinal fluid (CSF) volume is a risk factor for HFS is
