This paper presents an application of the dynamic reservation protocol on DECT systems for prioritized multirate mobile data services. This protocol allows data terminals to access uplink channels through contention-free reservations. It can adapt to traffic variations by dynamically changing the transmission cycle length. Since this protocol is built on the top of the DECT physical layer, it c...

conclusions telephone consultation partially based on a cognitive-behavioral approach significantly reduced the intensity of pain and improved the qol in patients with chronic pain in japan. results the pain intensities were significantly decreased from 7.6 ± 2.0 at baseline to 5.7 ± 2.9 on follow-ups assessed by a numerical rating scale (range; 0 - 10, p < 0.001, effect size (es); 0.76). the e...

Soft robots are those that can move like living organisms and adapt to the surrounding environment. Compared with traditional rigid robots, advantages of soft in terms material flexibility, human–computer interaction, biological adaptability, have received extensive attention. Flexible actuators based on light response one most promising ways promote field cordless they attracted attention scie...

Protocols and results of case-control studies, pooledand meta-analyses on the relationship between mobile phone use and risk of head tumours are critically analysed, and for each study strict elements necessary for evaluating its reliability are identified and applied (see Methods). In studies funded by public bodies, blind protocols give positive results revealing cause-effect relationships be...

Facemask removal (FMR) is essential when potential cervical spine injuries occur in athletes wearing helmets. Used football helmets produce high failure rates of screw removal; however, research on lacrosse helmets is lacking. This study aimed to determine the frequency of FMR failure in lacrosse helmets worn at least 1 season. The authors collected used helmets from 4 colleges (n = 172) and 4 ...
