Ob.ective:To evaluate the ef.ect of.ureteral access sheath(UAS)use and calib.ation change on stone-f.ee rate and complications of.retrograde intrarenal surgery(RIRS).Methods:Data f.om 568 patients undergoing RIRS f.r kidney or upper ureteral stones were retrospectively ***,patients were compared af.er 1:1 propensity score matching,according to UAS usage during RIRS(UAS used[+]87 and UAS non-used[−]87 patients).Then all UAS+patients(n=481)were sub.ivided according to UAS calib.ation:9.5-11.5 f.,10-12 f.,11-13 f.,and 13-15 *** outcomes of.the study were the success and complications of.***:Stone-f.ee rate of.UAS+patients(86.2%)was signif.cantly higher than UAS−patients(70.1%)af.er propensity score matching(p=0.01).Stone-f.ee rate increased with higher calib.r UAS(9.5-11.5 f.:66.7%;10-12 f.:87.0%;11-13 f.:90.6%;13-15 f.:100%;plications of.UAS+patients(11.5%)were signif.cantly lower than UAS−patients(27.6%)(p=0.01).Complications(8.7%)with 9.5-11.5 f. UAS was lower than thicker UAS(17.2%)b.t was not statistically signif.cant(p=0.09).UAS usage was an independent f.ctor predicting stone-f.ee status or peri-and post-operative complications(odds ratio[OR]3.654,95%conf.dence interval[CI]1.314-10.162;OR 4.443,95%CI 1.350-14.552;OR 4.107,95%CI 1.366-12.344,respectively).Conclusion:Use of.UAS in RIRS may increase stone-f.ee rates,which also increase with higher calib.r *** usage may reduce complications;however,complications seemingly increase with higher UAS calib.ation.

b.ckground: Orthodontics is a dental specialty f.cusing on correcting dental irregularities and malocclusion. Knowledge and attitudes towards orthodontic treatment are crucial f.r promoting oral health and overall well-b.ing. Education and awareness play a vital role in ensuring optimal treatment outcomes and improving quality of.lif.. Aim: This study aims to determine the knowledge and attitudes of.Kwame Nkrumah University of.Science and Technology (KNUST) pre-clinical dentistry students concerning orthodontic therapy. Methodology: This research is a quantitative descriptive cross-sectional study. The research used a non-random convenience sampling method to f.rm the desired sample. f.r data collection, an interview-administered questionnaire was used over one month. The study set its sights on pre-clinical dental students in KNUST. A total of.150 questionnaires were printed to meet the sample size. Results: The results of.the research showed that the knowledge level of.KNUST pre-clinical students on orthodontic treatment and its nuances is quite limited. They however had a f.ir level of.knowledge on the disease or ailment that orthodontic treatments solved (especially malocclusion). Their interest in orthodontic treatments on the other hand was quite signif.cant, with a large numb.r having interest in it. Conclusion: To conclude, KNUST pre-clinical students in Ghana although having a limited level of.knowledge on orthodontic treatments have a keen interest in undergoing them regardless of.the discomf.rts or the length of.time.

f.r more than a century, f.recasting models have b.en crucial in a variety of.f.elds. Models can of.er the most accurate f.recasting outcomes if.error terms are normally distrib.ted. f.nding a good statistical model f.r time series predicting imports in Malaysia is the main target of.this study. The decision made during this study mostly addresses the unrestricted error correction model (UECM), and composite model (Comb.ned regression—ARIMA). The imports of.Malaysia f.om the f.rst quarter of.1991 to the third quarter of.2022 are employed in this study’s quarterly time series data. The f.recasting outcomes of.the current study demonstrated that the composite model of.ered more prob.b.listic data, which improved f.recasting the volume of.Malaysia’s imports. The composite model, and the UECM model in this study are linear models b.sed on responses to Malaysia’s imports. f.ture studies might compare the perf.rmance of.linear and nonlinear models in f.recasting.

With the increased interest of.plants in space, gravity cannot b. ignored when studying soil-plant-water relations. Theref.re, it is important to understand the water relations of.soils under zero gravity in space or under reduced gravity on the Moon or Mars. This paper outlines the prob.ems of.moving water in soils under zero gravity or microgravity, as well as growing plants in these soils. It is suggested that microgravity experiments could b. done on Earth using b.th soils and plants. Results f.om such experiments could b. used to grow plants when mankind estab.ishes b.ses on the Moon and Mars.

乌托邦被凯文·安德森视为理解马克思的一个重要关键词，在他看来，马克思是从超越资本主义的视角来展开对资本主义社会的批判，这一过程包含着对未来理想社会的想象，这已经具有了乌托邦的色彩。乌托邦在马克思那里并不是一个单纯的学术课题，相反，它具有切实的实践含义并在当代积极地塑造着社会的面貌。在《马克思在边缘》一书中，安德森指出马克思克服了欧洲中心主义，逐渐对社会发展形成一种多线性的思维方式。以此为方法论，安德森对十月革命、爱尔兰革命和中国的革命运动展开了深入研究。

We use density f.nctional perturb.tion theory b.sed on the pseudo-potential to calculate the phonon spectrum, phonon density of.states, specif.c heat capacity and mechanical properties of.pristine and cob.lt doped （5,0） single wall carb.n nanotub. （CNT）. In the calculations, we consider one Co atom in the center of.the unit cell of.the tub. and it is shown that the pristine （5~0） CNT is nonmagnetic while the Co-doped tub. b.comes magnetic. Young＇s modulus f.r b.th systems is ab.ut 1 TPa （＇af.er Co-doping it goes slightly higher） and the Poisson ratio f.r the pristine tub. b.comes quite a b.t larger than the doped one. On the other hand, the calculated value of.radial b.eath mode f.r the pristine CNT is in good agreement with the experimental reports while af.er Co-doping it is increased. In addition, heat capacity of.the doped CNT is reduced, which leads to some important empirical applications.

Patients and physicians understand the importance of.self.care f.llowing spinal cord injury (SCI), yet many individuals with SCI do not adhere to recommended self.care activities despite logistical supports. Neurob.havioral determinants of.SCI self.care b.havior, such as impulsivity, are not widely studied, yet understanding them could inf.rm ef.orts to improve SCI self.care. We explored associations b.tween impulsivity and self.care in an ob.ervational study of.35 US adults age 18 - 50 who had traumatic SCI with paraplegia at least six months b.f.re assessment. The primary outcome measure was self.reported self.care. In lASSO regression models that included all neurob.havioral measures and demographics as predictors of.self.care, dispositional measures of.greater impulsivity (negative urgency, lack of.premeditation, lack of.perseverance), and reduced mindf.lness were associated with reduced self.care. Outcome (magnitude) sensitivity, a latent decision-making parameter derived f.om computationally modeling successive choices in a gamb.ing task, was also associated with self.care b.havior. These results are preliminary;more research is needed to demonstrate the utility of.these f.ndings in clinical settings. Inf.rmation ab.ut associations b.tween impulsivity and poor self.care in people with SCI could guide the development of.interventions to improve SCI self.care and help patients with elevated risks related to self.care and secondary health conditions.
