Hydrochemical Characteristics of Four Retreating Glacier Forefields Off the Coast of Admiralty Bay (King George Island, Maritime Antarctic): Diverse Sources of Metals and Metalloids

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT This study examines the impact of geological, marine and anthropogenic sources on metal and metalloid concentrations in the forefields of four glaciers (Ecology, Sphinx, Tower and Windy) on King George Island, Antarctic. Water samples were collected at the beginning and end of the hydrological season (austral summer, December 2021 to February ...

Fiber over Wireless Chromatic Dispersion Compensation for a Better Quality of Service

open access: yesEURASIP Journal on Wireless Communications and Networking, 2006
"Anywhere" and, in particular, "anyhow": these are the two best words that can describe an ad hoc wireless network that is due to the increasing demand for connectivity in such an information society. Ad hoc wireless networks can be described as dynamic

The Mild Behavioral Impairment Checklist for Parkinson's Disease: An Ancillary Instrument in Cognitive Assessment

open access: yesMovement Disorders Clinical Practice, EarlyView.
Abstract Background Mild behavioral impairment (MBI) is a syndrome characterized by the later‐life onset of neuropsychiatric symptoms (NPS) and serves as a potential marker for dementia. In Parkinson's disease (PD), MBI has been associated with worse cognition, cortical atrophy, and altered connectivity.

Database Exchanges for Ad-hoc Networks Using Proactive Link State Protocols [PDF]

open access: yes, 2009
International audienceThe OSPF routing protocol is currently the predominant IGP in use on the fixed Internet of today. This routing protocol scales ''world wide", under the assumptions of links being relatively stable, network density being rather low ...

Urban wild meat and pangolin consumption across southern forested Cameroon: The limited influence of COVID‐19

open access: yesPeople and Nature, EarlyView.
Abstract Overexploitation of wildlife is pervasive in many tropical regions, and in addition to being a significant conservation and sustainability concern, it has received global attention given discussions over the origins of zoonotic disease outbreaks.

Predictive geographic multicast routing protocol in flying ad hoc networks

open access: yesInternational Journal of Distributed Sensor Networks, 2019
In the past decades, the unmanned aerial systems have been utilized only for military operations. However, recently, the potential uses and applicability of unmanned aerial vehicles (commonly known as drones) in civilian application domains are becoming ...

Wireless Sensor Networks Fault-Tolerance Based on Graph Domination with Parallel Scatter Search

open access: yesSensors, 2020
In wireless sensor/ad hoc networks, all wireless nodes frequently flood the network channel by transmitting control messages causing “broadcast storm problem”. Thus, inspired by the physical backbone in wired networks, a Virtual Backbone (VB) in wireless

TCP Performance in Ad Hoc Networks [PDF]

open access: yes, 2000
Ad hoc networks are mobile wireless networks which do not have any kind of fixed infrastructure. The routing layer in an ad hoc network ties the network together into a seamless entity and provide transparent services to higher layer protocols.

Docosahexaenoic acid ameliorates autistic‐like behaviors by inhibiting oxidative stress and inflammatory response in neonatal maternal separation rats

open access: yesPediatric Discovery, EarlyView.
The JNK pathway and oxidative stress are activated, and pro‐inflammatory cytokines are increased in neonatal maternal separation (NMS) rats. While docosahexaenoic acid treatment suppresses the activation of JNK pathway and oxidative stress, and reduces pro‐inflammatory cytokines release, thereby improving autism‐like behavior induced by NMS.

Enhanced group-based wireless ad-hoc sensor network protocol

open access: yesInternational Journal of Distributed Sensor Networks, 2016
Communication is the major energy consumption source in wireless ad-hoc sensor networks. Thus, an efficient trade-off between the energy cost of the communication and network’s performance is a key challenge in conceiving a wireless ad-hoc sensor network.
