Using angle-resolved photoemission spectroscopy (ARPES) and density functional theory (DFT), an experimental and theoretical study of changes in the electronic structure (dispersion dependencies) and corresponding modification of the energy band gap at the Dirac point (DP) for topological insulator (TI) [Formula: see text] have been carried out with gradual replacement of magnetic Mn atoms by non-magnetic Ge atoms when concentration of the latter was varied from 10% to 75%. It was shown that when Ge concentration increases, the bulk band gap decreases and reaches zero plateau in the concentration range of 45-60% while trivial surface states (TrSS) are present and exhibit an energy splitting of 100 and 70 meV in different types of measurements. It was also shown that TSS disappear from the measured band dispersions at a Ge concentration of about 40%.

Article Synopsis
- The study evaluates parenchymal volume analysis (PVA) as a potential alternative to nuclear renal scan (NRS) for assessing split renal function (SRF) before and after partial nephrectomy (PN) with warm ischemia.
- Preoperatively, PVA showed a strong correlation with NRS findings, indicating its reliability for SRF assessment (49.4% vs. 50.0%, P = .501).
- Results suggest that while PVA is consistent with NRS preoperatively, the efficacy of PVA remains uncertain for post-operative SRF evaluation after PN, indicating a need for further investigation.

Article Synopsis
- The paper discusses a new control algorithm for robotic manipulators that addresses issues like complex structures and uncertainties.
- It utilizes fuzzy set theory to tackle system uncertainties and ensures the system's performance remains stable (uniform boundedness and uniform ultimate boundedness).
- The proposed method has been validated through numerical simulations and experiments, demonstrating its effectiveness in optimizing controller settings.
Ten-Year Implant Survivorship and Performance of Anatomic Total Shoulder Arthroplasty Patients with the Zimmer Biomet Comprehensive® Shoulder System - a Short Stemmed Humeral Implant and Hybrid Glenoid.

Background: Anatomic total shoulder arthroplasty are highly successful procedures for treatment of glenohumeral arthritis to reduce pain, improve range of motion, and overall quality of life. However, the long-term survivorship of the implant systems is less widely documented in the existing literature. The purpose of this study was to establish the long-term patient outcomes and identify factors influencing the postoperative implant survivorship of total anatomic shoulder arthroplasty devices/procedures utilizing the short-stemmed prosthesis and hybrid glenoid components of the Comprehensive Shoulder System (Zimmer Biomet, Warsaw, IN, USA) at an average of ten years.

This study investigates the neural and physiological mechanisms underlying External Referent Decision Awareness (ERDA) within organizational contexts, focusing on hierarchical roles (Head, Peer, Staff). Twenty-two professionals participated, and electroencephalographic (EEG frequency band: Delta, Theta, Alpha, Beta, Gamma) and autonomic indices (skin conductance and cardiovascular indices) were recorded, while personality traits and decision-making styles were assessed. Results revealed higher Delta and Theta activation in the left temporo-parietal junction (TPJ) during Peer-related decisions, reflecting increased social cognition and ambiguity regulation in those contexts.
