A Passive RF Testbed for Human Posture Classification in FM Radio Bands.

This paper explores the opportunities and challenges for classifying human posture in indoor scenarios by analyzing the Frequency-Modulated (FM) radio broadcasting signal received at multiple locations. More specifically, we present a passive RF testbed operating in FM radio bands, which allows experimentation with innovative human posture classification techniques. After introducing the details of the proposed testbed, we describe a simple methodology to detect and classify human posture.

Use of rubber dam versus cotton roll isolation on composite resin restorations' survival in primary molars: 2-year results from a non-inferiority clinical trial.

Background: This non-inferiority randomised clinical trial aimed to evaluate the survival of direct bulk fill composite resin restorations in primary molars using different methods of moisture control: rubber dam isolation (RDI-local anaesthesia and rubber dam) and cotton roll isolation (CRI-cotton roll and saliva ejector). Secondary outcomes included baseline and 2-year incremental cost, self-reported child's pain scores and patient behaviour during the restorative procedure.

Methods: A total of 174 molars (93 children) with dentine caries lesions were randomly allocated to study groups (RDI or CRI) and restored with bulk fill composite resin by trained operators.

Linear and Non-Linear Soft Sensors for Predicting the Research Octane Number (RON) through Integrated Synchronization, Resolution Selection and Modelling.

The Research Octane Number (RON) is a key quality parameter for gasoline, obtained offline through complex, time-consuming, and expensive standard methods. Measurements are usually only available a few times per week and after long delays, making process control very challenging. Therefore, alternative methods have been proposed to predict RON from readily available data.

INTENSIVE CARE UNIT PRESCRIPTIONS MUST FIT RISK FACTORS TO PREVENT STRESS ULCER BLEEDING.

Background: The physiological stress of critically ill patients can trigger several complications, including digestive bleeding due to stress ulcers (DBSU). The use of acid secretion suppressants to reduce their incidence has become widely used, but with the current understanding of the risks of these drugs, their use, as prophylaxis in critically ill patients, is limited to the patients with established risk factors.

Aim: To determine the appropriateness of the use of prophylaxis for stress ulcer bleeding in acutely ill patients admitted to intensive care units and to analyze the association of risk factors with adherence to the prophylaxis guideline.

The economic impact of two diagnostic strategies in the management of restorations in primary teeth: a health economic analysis plan for a trial-based economic evaluation.

Background: Different approaches have been used by dentists to base their decision. Among them, there are the aesthetical issues that may lead to more interventionist approaches. Indeed, using a more interventionist strategy (the World Dental Federation - FDI), more replacements tend to be indicated than using a minimally invasive one (based on the Caries Around Restorations and Sealants-CARS).

Survival rate of primary molar restorations is not influenced by hand mixed or encapsulated GIC: 24 months RCT.

Background: Glass ionomer cements (GIC) have been considered the top option to restore primary teeth by dentists. The most common supply forms are hand mixed and encapsulated GIC. There is a lack of information about the impact of different GIC supply forms on restoration survival.

Structure-Based Molecular Networking for the Target Discovery of Oxahomoaporphine and 8-Oxohomoaporphine Alkaloids from .

In addition to seven known alkaloids (, -) and 1,2,4-trimethoxybenzene (), three isoquinoline-derived alkaloids (-), namely, duguetinine (), a compound based on an unprecedented oxahomoaporphine scaffold, and two new 8-oxohomoaporphine alkaloids, duguesuramine () and 11-methoxyduguesuramine (), and a new asarone-derived phenylpropanoid () were isolated from the bark of . The isolation workflow was guided by HPLC-HRESIMS/MS and molecular networking-based analyses. Twenty-four known alkaloids were dereplicated from the alkaloid-rich fraction network and were assigned by manual MS/MS interpretation.

Simultaneous determination of caffeine, theobromine, and theophylline by high-performance liquid chromatography.

This work relates the development of an analytical methodology to simultaneously determine three methylxanthines (caffeine, theobromine, and theophylline) in beverages and urine samples based on reversed-phase high-performance liquid chromatography. Separation is made with a Bondesil C18 column using methanol-water-acetic acid or ethanol-water-acetic acid (20:75:5, v/v/v) as the mobile phase at 0.7 mL/min.
