The Shehata technique for undescended testes that cannot be brought into the scrotum in one operation-a case series and meta-analysis.

Background: Fowler-Stephens orchiopexy is commonly used for testes that cannot be brought into the scrotum in one operation. However, this surgical technique may result in a higher rate of testicular atrophy postoperatively.

Methods: During the period between 2019 and 2023, we analyzed the cases of 20 patients in whom the Shehata technique was applied for testes that could not be brought into the scrotum in one operation, and we conducted a meta-analysis to explore the incidence of testicular atrophy vis-à-vis the Shehata technique and Fowler-Stephens orchiopexy.

Event-Triggered Output-Feedback Control for Synchronization of Delayed Neural Networks.

This article proposes a novel discrete event-triggered scheme (DETS) for the synchronization of delayed neural networks (NNs) using the dynamic output-feedback controller (DOFC). The proposed DETS uses both the current and past samples to determine the next trigger, unlike the traditional event-triggered scheme (ETS) that uses only the current sample. The proposed DETS is employed in a dual setup for two network channels to significantly reduce redundant data transmission.

A sum-based discrete event-triggered dynamic output feedback control for interval type-2 fuzzy systems.

The current study concentrates on the event-based controller design for nonlinear networked systems characterized by the interval type-2 (IT2) fuzzy model. An innovative sum-based discrete event-triggered mechanism (SDETM), whose triggering condition includes several previous measurement samples, is proposed. Compared to the traditional event-triggered mechanism (ETM), the novel SDETM requires less network resources consumption.

Toward Noise-Resistant Graph Embedding With Subspace Clustering Information.

Most existing approaches of attributed network embedding often combine topology and attribute information based on the homophily assumption. In many real-world networks, such an assumption does not hold since the nodes are usually associated with many noisy or irrelevant attributes. To tackle this issue, we propose a noise-resistant graph embedding method, called NGE, by leveraging the subspace clustering information (i.

In Situ Hydrogen Peroxide Production for Selective Oxidation of Benzyl Alcohol over a Pd@Hierarchical Titanium Silicalite Catalyst.

Using in situ generated HO is potentially an effective approach for benzyl alcohol selective oxidation. While the microporous titanium silicate (TS-1) supported with Pd is promising for selective oxidation, the Pd particles are preferentially anchored on the external surface, which leads to the problems such as non-uniform dispersion and low thermal stability. Here, we prepared a Pd@HTS-1 catalyst in which the Pd subnanoparticles were encapsulated in the channels of the hierarchical TS-1 (HTS-1), for benzyl alcohol selective oxidation with in situ produced HO.

The effectiveness and safety of topical β-receptor blocker in treating superficial infantile haemangiomas: A meta-analysis including 20 studies.

Aims: To evaluate the effectiveness and safety of topical β-receptor blocker in treating superficial infantile haemangiomas (SIH) and compare the effectiveness and safety of topical β-receptor blocker against other therapies.

Methods: A search of the literature using PubMed, Embase, Cochrane Review database, China National Knowledge Infrastructure and Wanfang were performed to identify the studies that estimated the effectiveness and safety of topical β-receptor blocker in treating SIH, the fixed-effect or random-effects meta-analytical techniques were applied to assess the outcomes.

Results: Twenty studies, involving 2098 patients, were included to conduct this analysis.
