We present results including measurement and analysis of titanium monoxide. Pulsed, nanosecond Nd:YAG laser radiation is used in a typical laser-induced breakdown spectroscopy arrangement to record the spectra. This scheme provides experiments analogous to pulsed laser deposition tactics and allows for time-resolved spectroscopic analysis. The computed spectra are generated from a new, accurate line-strength file that allows us to accurately predict γ (A3Φ→X3Δ) and γ' (B3Π→X3Δ) spectral signatures. We infer temperature on the order of 3600±700 K and 4200±800 K at time delays of 52 and 72 μs, respectively. Current interest in this work includes titania (TiO2) nanoparticle generation for thin film applications.

Background: Little is known about the role that charitable copay assistance (CPA) plays in addressing access to care and financial distress. The study sought to evaluate financial distress and experience with CPA among patients with cancer and autoimmune disease.
Methods: This is a national cross-sectional self-administered anonymous electronic survey conducted among recipients of CPA to cover the costs of a drug for cancer or autoimmune disease.

Purpose: This study aims to examine the relationships between organizational culture, employee loyalty, trust and job satisfaction within the Lebanese health-care sector. It addresses the critical need to improve employee retention and organizational performance in a context marked by economic instability and political uncertainty. By analyzing data from 270 health-care professionals, the study aims to explore how different aspects of organizational culture - such as transparency, supportiveness and ethical leadership - affect employee trust and satisfaction.

Importance: Lung ultrasound (LUS) aids in the diagnosis of patients with dyspnea, including those with cardiogenic pulmonary edema, but requires technical proficiency for image acquisition. Previous research has demonstrated the effectiveness of artificial intelligence (AI) in guiding novice users to acquire high-quality cardiac ultrasound images, suggesting its potential for broader use in LUS.
Objective: To evaluate the ability of AI to guide acquisition of diagnostic-quality LUS images by trained health care professionals (THCPs).

Importance: Surgeon stress can influence technical and nontechnical skills, but the consequences for patient outcomes remain unknown.
Objective: To investigate whether surgeon physiological stress, as assessed by sympathovagal balance, is associated with postoperative complications.
Design, Setting, And Participants: This multicenter prospective cohort study included 14 surgical departments involving 7 specialties within 4 university hospitals in Lyon, France.

Mechanical properties of engineered connective tissues are critical for their success, yet modern sensors that measure physical qualities of tissues for quality control are invasive and destructive. The goal of this work was to develop a noncontact, nondestructive method to measure mechanical attributes of engineered skin substitutes during production without disturbing the sterile culture packaging. We optimized a digital holographic vibrometry (DHV) system to measure the mechanical behavior of Apligraf living cellular skin substitute through the clear packaging in multiple conditions: resting on solid agar as when the tissue is shipped, on liquid media in which it is grown, and freely suspended in air as occurs when the media is removed for feeding.
