Evaluation of Cluster Algorithms for Radar-Based Object Recognition in Autonomous and Assisted Driving.

Perception systems for assisted driving and autonomy enable the identification and classification of objects through a concentration of sensors installed in vehicles, including Radio Detection and Ranging (RADAR), camera, Light Detection and Ranging (LIDAR), ultrasound, and HD maps. These sensors ensure a reliable and robust navigation system. Radar, in particular, operates with electromagnetic waves and remains effective under a variety of weather conditions.

Toxicity and Dermatokinetic Analysis of Ibrutinib in Human Skin Models.

Ibrutinib (IBR) is a tyrosine kinase inhibitor under investigation in preclinical and clinical settings as an alternative treatment for melanoma. Nevertheless, the limited oral bioavailability of IBR and the need for high doses of the drug to kill melanoma cells are major drawbacks for this purpose. Considering that melanoma is restricted to the skin at early stages, the topical application of IBR might constitute an effective and safer administration route.

Network Analysis of Pathogenesis Markers in Murine Chagas Disease Under Antimicrobial Treatment.

Chagas disease (CD), a disease affecting millions globally, remains shrouded in scientific uncertainty, particularly regarding the role of the intestinal microbiota in disease progression. This study investigates the effects of antibiotic-induced microbiota depletion on parasite burden, immune responses, and clinical outcomes in BALB/c mice infected with either the Colombiana or CL Brener strains. Mice were treated with a broad-spectrum antibiotic cocktail before infection, and parasite burden was quantified via qPCR at 30 and 100 days post-infection (dpi).

Hatching Egg Sanitizers Based on Essential Oils: Microbiological Parameters, Hatchability, and Poultry Health.

Eggshell contamination threatens the viability of hatching eggs. This contamination can be caused by harmless, opportunistic, or pathogenic bacteria. Although necessary, the use of synthetic antibiotics to treat eggshells can present several significant problems: They can be toxic and damage the shell, and, most worryingly, they can lead to bacterial resistance.

Sustainable Bacterial Control of Hatching Eggshells Using Essential Oils.

Decontamination of poultry surfaces through appropriate hygiene and sanitation measures can partially mitigate bacterial problems, as this process does not result in the complete elimination of bacteria. Thus, the remaining bacteria can persist and contaminate eggshells. Therefore, regardless of the rigor of the sanitary standards applied on farms, it is suggested that hatching eggs be subjected to the sanitization process.

Two-dimensional electrophoresis, graphite furnace atomic absorption spectrometry, and liquid chromatography-tandem mass spectrometry were performed. Hg and Se determinations allowed the calculation of Hg:Se and Se:Hg molar ratio and Se values for health benefits (Se HBVs).

Surveillance of SARS-CoV-2 in Healthcare Workers Before and After COVID-19 Vaccination: A Cohort Study in a Primary Care Unit of Brazil.

Introduction: Healthcare workers (HCWs) are at higher risk of SARS-CoV-2 infection. Viral surveillance for early detection of COVID-19 is a critical strategy to understand this population's infection dynamics and prevent transmission. The study examines SARS-CoV-2 infection and reinfection among HCWs vaccinated against COVID-19 working at a primary healthcare unit serving a disenfranchised community in Brazil.

Statistical Properties of Superpositions of Coherent Phase States with Opposite Arguments.

We calculate the second-order moments, the Robertson-Schrödinger uncertainty product, and the Mandel factor for various superpositions of coherent phase states with opposite arguments, comparing the results with similar superpositions of the usual (Klauder-Glauber-Sudarshan) coherent states. We discover that the coordinate variance in the analog of even coherent states can show the most strong squeezing effect, close to the maximal possible squeezing for the given mean photon number. On the other hand, the Robertson-Schrödinger (RS) uncertainty product in superpositions of coherent phase states increases much slower (as function of the mean photon number) than in superpositions of the usual coherent states.

Upper-Extremity physical performance tests in older adults: Reference values, reliability and measurement error.

Background: Physical performance tests are reliable tools to assess aspects related to strength, power, and mobility. Unfortunately, few studies were performed with older adults. The main goal of this study was to describe reference values for the Closed Kinetic Chain Upper Extremity Stability Test (CKCUEST) and Upper Quarter Y Balance Test (UQYBT) in older adults and to determine differences based on sex.

Adaptative Variation in a Neotropical Dung Beetle: Females and Gamma Males Present Tunneler Morphology, While Beta and Alpha Males Present Wing Morphology for Velocity.

In evolutionary terms, plastic traits can covary, providing adaptive value by compensating for certain characteristic costs or enhancing fitness. This combination of traits is expected in species with significant intrapopulation ecological variation, like insects. In the Phanaeini tribe, males and females have distinct nesting behaviors, and the alpha, beta, and gamma morphotypes of trimorphic males display different reproductive strategies.

Tumor-Infiltration Mimicking Model of Contaminated Ovarian Tissue as an Innovative Platform for Advanced Cancer Research.

The development of advanced preclinical models is crucial for the evaluation and validation of novel therapeutic strategies in oncology. Three-dimensional (3D) microtumor models, which incorporate both cancer and stromal cells within biomimetic hydrogels, have emerged as powerful tools that more accurately replicate the complex tumor microenvironment compared to traditional two-dimensional (2D) cell culture systems. In this context, our study aims to develop 3D microtumor models by integrating cancer and stromal cells within an extracellular-matrix-mimetic hydrogel, as a physiologically accurate microtumor model that can serve as an innovative platform for advanced cancer research and drug screening.
