Short Range Indoor Distance Estimation by Using RSSI Metric

Electrica, 2017
In recent years, indoor localizationproblem is a highly preferred topic to study. In order to estimate the relativepositions of the communication nodes in a localization system, the distanceinformation of each node is required. In this paper, it is aimed

Treatment With the Shaker Head‐Lift Exercise in Head and Neck Cancer Patients With Radiation‐Induced Dysphagia: 12‐Month Results on Swallowing Function From a Randomized, Controlled Trial

Head &Neck, EarlyView.
ABSTRACT Background Dysphagia is a common side‐effect after radiotherapy in head and neck cancer patients. This randomized study aimed to evaluate the effect of the shaker head‐lift exercise (HLE) after 12 months with flexible endoscopic evaluation of swallowing (FEES). Methods Patients were randomly assigned to the intervention (n = 30) or the control

Drought intensifies dominant competitor avoidance and risk‐dependent habitat selection in a large carnivore guild

Oikos, EarlyView.
Intraguild competition is a key force structuring predator communities, with dominant species impacting subordinate species' space use and access to resources. Climate change may intensify or reshape these processes, yet how climate conditions interact with dominance to influence predator space use and resource selection remains poorly understood.
