GO‐Loading‐Dependent Interfacial Architecture and Photocatalytic Behavior of MoSe2/Graphene Oxide Hybrid Materials

Journal of the Chinese Chemical Society, EarlyView.
MoSe2/GO heterostructure exhibits enhanced photocatalytic dye degradation and CO2 reduction through efficient charge separation and electron transfer under UV‐visible light irradiation. ABSTRACT MoSe2/graphene oxide (MoSe2/GO) hybrids with controlled GO loadings were prepared through an ex‐situ hydrothermal route using commercial MoSe2 and GO as ...

Point‐Of‐Care Ultrasound for the Assessment of the Cerebroplacental Ratio in Near‐Term Pregnancies: An Agreement Study With Conventional Ultrasound

Journal of Clinical Ultrasound, EarlyView.
In 80 singleton pregnancies at term, handheld point‐of‐care ultrasound (POCUS) was compared with conventional ultrasound for fetal Doppler assessment. Umbilical artery PI, middle cerebral artery PI, and cerebroplacental ratio showed agreement between devices. Between‐device variability was comparable to intra‐observer repeatability, supporting handheld

GSK3 Inhibition During Annelid Head Regeneration Results in a Hyper‐Proliferative Blastema and Impaired Differentiation

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
A whole‐body regenerative annelid was treated with a GSK3 inhibitor. While posterior regeneration was mostly normal, GSK3 inhibition prevented differentiation of anterior‐specific structures and instead produced a persistent, oversized, hyper‐proliferative blastema. This suggests that GSK3 promotes anterior identity and halts proliferation during axial

Absence of progressive liver disease after treatment in children with chronic hepatitis C: A nationwide registry study

Journal of Pediatric Gastroenterology and Nutrition, EarlyView.
Abstract Objectives In adults with chronic hepatitis C (CHC) and advanced fibrosis, hepatocellular carcinoma (HCC) surveillance is recommended after achieving a sustained virologic response (SVR). However, post‐SVR surveillance strategies for children remain unclear. The aim of this study was to assess the durability of SVR and determine an appropriate

Effects of post‐hepatic portoenterostomy adjuvant therapy on liver transplantation in children with biliary atresia: A systematic review

JPGN Reports, EarlyView.
Abstract Objectives Biliary atresia (BA) is a cholangiopathy characterized by obstruction of the intrahepatic and extrahepatic bile ducts. Hepatic portoenterostomy (HPE) is the primary palliative treatment and there is still an urgent need to improve post‐HPE management.

Adaptability in the B-MAC+ Protocol

2008 IEEE International Symposium on Parallel and Distributed Processing with Applications, 2008
In order to obtain maximum energetic efficiency, wireless sensor networks must be able to tailor their mode of operation at every level of the software infrastructure. At the MAC level, adaptability can greatly improve the performance of the system by tuning the parameters of operation of the protocol on the base of the communication pattern of the ...

MAC-ASA: A New MAC Protocol for WMNs

2007 16th International Conference on Computer Communications and Networks, 2007
This paper presents a novel medium access control (MAC) protocol intended to provide multi-hop wireless mesh networks with a higher throughput. The proposed MAC-ASA (medium access control with anticipated scheduling and agreement) protocol uses a modified version of the 802.11 CSMA/CA contention handling procedure integrated with a dynamic (time ...

A Review of UWB MAC Protocols

2010 Sixth Advanced International Conference on Telecommunications, 2010
In this paper, we review several ultra-wideband (UWB) medium access control (MAC) protocols that have been proposed to date. This review then considers the possibility of developing an optimal MAC layer for high data rate UWB transmission systems that transmit very little power especially in application to mobile devices.

The Demand Priority MAC protocol

IEEE Network, 1995
A new technology needs to offer more than just 100 Mb/s. To succeed in the LAN marketplace, a new LAN technology must be very cost competitive with the established LANs, such as Ethernet and Token Ring, while also providing backwards compatibility with existing network software.

A Survey on the Programmability of Wireless MAC Protocols [PDF]

IEEE Communications Surveys and Tutorials, 2019
Self-organizing networks able to adapt to changes in the environment have already been a longstanding research topic. Given the limited number of license-free industrial, scientific, and medical radio bands, wireless technologies end up competing with one another for the wireless spectrum.
