In a holographic superfluid disk, when the rotational velocity is large enough, we find that a giant vortex will form in the center of the system by merging several single charged vortices at some specific rotational velocity with a phase stratification phenomenon for the order parameter. The formation of a giant vortex can be explained, as there is not enough space for a standard vortex lattice. If we keep increasing the rotational velocity, the giant vortex will disappear and there will be an appearance of a superfluid ring. In the giant vortex region, the number of vortices measured from winding number and rotational velocity always satisfies the linear Feynman relation. However, when the superfluid ring starts to appear, the number of vortices in the disk will decrease although the rotational velocity is increasing, while most of the order parameter is suppressed.

Bell's palsy is a form of idiopathic, facial nerve palsy. Initial treatment includes the use of oral corticosteroids and/or antiviral agents, but facial paralysis may persist. Some surgeons suggest that surgical decompression of the facial nerve can be a beneficial, but the optimal surgical approach, extent of nerve decompression, and timing of surgery remain unclear.This study intended to evaluate the efficacy of delayed, facial nerve decompression for severe Bell's palsy (BP) and to explore the relationship of opportunity timing for operations, with postoperative recovery for facial nerve function.The research team performed a retrospective study.The study took place at Beijing Tiantan Hospital of Capital Medical University in Beijing, China.Participants were 45 patients who had been diagnosed with BP between 2015 and 2021 and who had undergone facial nerve decompression using the transmastoid approach, between 30 and 180 days after the onset of BP. According to the operation's timing, the research team divided the participants into three groups, consisting of participants who underwent surgery: (1) at 30-60-days after BP onset-19 participants, (2) at 61-90 days after BP onset-18 participants, and (3) at more than 90 days after BP onset-8 participants.The research team: (1) analyzed participants' demographic and preoperative and postoperative clinical characteristics, (2) compared the surgical outcomes with participants' House-Brackmann (HB) scales, and (3) analyzed the factors affecting the recovery of facial nerve function using logistic regression.Decompression surgery was effective for 29 participants (64.4%), with similar rates for participants who underwent surgery after 30-60 days (73.7%) and 61-90 days (77.8%), but the surgery' success was significantly higher for those groups than for participants who underwent surgery after90 days (12.5%), with P = .008 and P = .003, respectively. Multivariate logistic regression analysis showed that disease duration was the only factor significantly associated with the effectiveness of surgery (odds ratio = 120.337; 95% confidence interval 2.997-4832.267, P = .011).For patients with severe Bell's palsy with ineffective conservative treatment, surgery performed 30 to 90 days after the onset of paralysis can have therapeutic benefits, whereas surgery performed after 3 months is relatively ineffective.

As multifunctional luminescence sensor, EU MOF has good thermal stability and water stability. It is used for the detection of Fe3+, Cr2O72−, CrO42− and aspartic acid in water system with low detection limit. And it has good recycling performance.

Persuasive technology in online shopping is proven to assist people while purchasing online. It is crucial to study how was the implementation of such successful persuasive technology in the e-commerce domain. Also, there are certain marketing strategies against consumers from different generational cohorts. Each generation has unique lifestyles, generational history, demographics, experiences, expectations and values that influence their buying behaviours. The persuasive design of e-commerce websites is related to the website conversion rate and is shown to support people throughout the online purchasing process. The objective of this research study is to evaluate the online persuasion criteria on two largest e-commerce websites in Malaysia; Lazada and Shopee through Persuasive System Design (PSD) principles. The four main categories of design technique applied in PSD are primary task support, dialogue support, credibility support and social support. The result shows that both selected e-commerce websites have applied 71.43% of the PSD principles. The most emphasize design technique in Lazada and Shopee is primary task support, followed by dialogue support. Most of the persuasive features in this model has implemented in both e-commerce websites. However, this research proved that the success of the e-commerce websites is related with the implemented persuasive feature which can be manipulated and implemented by other e-commerce websites.
