The physical properties of the series CePd3Be(x) (0 ≤ x ≤ 0.47) have been studied. Introducing Be into CePd3 results in a drastic reduction of the Seebeck coefficient from 100 μV K(-1) at 300 K to -2 μV K(-1), respectively. Paramagnetism of Ce(3+) free ions and metallic conduction dominate the physical properties. A structural transition at x = 0.25 is accompanied by a significant lowering of the Kondo temperature and leads to a successive suppression of the thermoelectric performance of CePd3Be(x) with increasing x.

A cross-sectional study comparing passive and eccentric modes of an isokinetic dynamometer to assess eccentric torque in trained athletes: Methodological considerations.

Some technical limitations to using the eccentric mode to measure peak eccentric strength of the hamstrings (PTH) were raised. PTH also has limited validity to predict performance or injury risk factor. Therefore, our aim was to compare PTH and other isokinetic variables tested in the eccentric and passive modes.

The heterogeneity of Pinus yunnanensis plantation growth was driven by soil microbial characteristics in different slope aspects.

State Key Laboratory of Tree Genetics and Breeding, Institute of Highland Forest Science, Chinese Academy of Forestry, Kunming, 650233, PR China.
The slope aspect is an important environmental factor, which can indirectly change the acceptable solar radiation of forests. However, the mechanism of how this aspect changes the underground ecosystem and thus affects the growth of aboveground trees is not clear. In this study, Pinus yunnanensis plantation was taken as the research object, and the effects of soil and microbial characteristics on tree growth under different slope aspects and soil depths were systematically analyzed.

Background: Recent studies have emphasized the association between prolonged screen exposure and neurodevelopmental disorders, though its correlation with tic disorders (TDs) remains ambiguous. We thus conducted this study to investigate the association between screen time (ST) and the severity of tic symptoms in children diagnosed with TDs.
Methods: We conducted a retrospective case-control study with 342 cases of TDs and 270 controls, collecting data from March 2021 to December 2023.
Background: Intrabdominal pressure (IAP) is an important parameter. Elevated IAP can reduce visceral perfusion, lead to intraabdominal hypertension, and result in life-threatening abdominal compartment syndrome. While ingestible capsular devices have been used for various abdominal diagnoses, their application in continuous IAP monitoring remains unproven.
