Visible Octave Frequency Combs in Silicon Nitride Nanophotonic Waveguides Driven by Ti:Sapphire Lasers

open access: yesLaser &Photonics Reviews, EarlyView.
Chip‐based frequency combs are usually pumped from telecom wavelengths, far from the visible. This work instead pumps close to the visible with a Ti:sapphire laser ‐ the source behind the original optical frequency combs and now becoming chip‐integrable‐ and lets silicon‐nitride waveguides convert it into efficient, octave‐spanning visible‐to‐infrared ...

传送MPLS(T-MPLS)体系的接口

open access: yesGuangtongxin yanjiu, 2006
传送多协议标签交换(MPLS)(T-MPLS)体系(TMH)是目前传送网技术研究的主要热点之一。随着IP技术的迅速发展和在服务质量(QoS)提高方面的需求,MPLS是重要解决方案。当前的传送网依然是以基于时分复用(TDM)技术为主(例如SDH)的光传送网络。如何在现有传送网上传送MPLS客户信号,是大家非常关注的问题。由于网络互连互通的需要,对于网络互连的接口必须要有统一的规范。文章重点介绍TMH的接口规范,包括TMH接口位置、网络节点接口(NNI)的基本信号结构、T-MPLS NNI接口的信息结构、T-

Prospective comparison of chronic pain and quality of life in dogs presenting with five common orthopaedic conditions

open access: yesVeterinary Record, EarlyView.
Abstract Background Chronic pain, which affects multiple aspects of dogs' wellbeing, including quality of life (QoL), was assessed in dogs with elbow dysplasia, hip dysplasia, medial patella luxation, cranial cruciate ligament rupture or osteoarthritis.

Reference Points and Affordability Perceptions of Hybrid Maize Seed in Uganda: Evidence on Endowment and Expectations

open access: yesJournal of Agricultural Economics, EarlyView.
ABSTRACT Despite demonstrated yield advantages, adoption of hybrid maize seed in Sub‐Saharan Africa remains low, raising questions about smallholders' perceptions of value and affordability. We examine whether farmers value hybrid maize seed differently depending on whether they already possess it or form expectations about likely prices or ownership ...

MPLS-TP分组传送网与现有网络互联互通的实现

open access: yesGuangtongxin yanjiu, 2008
在光传送网向分组传送网演进的过程中,网络之间的互联互通是运营商关心的主要问题之一。文章简要介绍了MPLS-TP(MPLS Transport Profile)分组传送网的网络构成,分析了在多种传送网并存的情况下,基于MPLS-TP分组传送网的多层网络结构,重点讨论了MPLS-TP分组传送网与IP/MPLS网络以及SDH/MSTP网络之间互联互通的实现方案。

The Functional Role and Molecular Characterization of the Therapeutic Target CLDN6 in Germ Cell Tumors

open access: yesAndrology, EarlyView.
ABSTRACT Background The tight junction protein CLDN6 has been identified as a cancer‐associated cell surface marker that is rarely expressed in healthy tissues. In testicular germ cell tumors (GCT), CLDN6 is particularly detectable in seminomas, embryonal carcinomas, and choriocarcinomas.

Distinct clinical and genetic characteristics of myelodysplastic syndrome in younger patients

open access: yesBritish Journal of Haematology, EarlyView.
Summary Myelodysplastic neoplasms (formerly myelodysplastic syndromes, MDS) are heterogeneous clonal haematological malignancies that primarily affect the elderly, though a notable proportion of patients are diagnosed at younger ages. We retrospectively analysed 1437 patients diagnosed or treated at Asan Medical Center between 1989 and 2022, comparing ...
