Machine learning method for the classification of the state of living organisms' oscillations.

The World Health Organization highlights the urgent need to address the global threat posed by antibiotic-resistant bacteria. Efficient and rapid detection of bacterial response to antibiotics and their virulence state is crucial for the effective treatment of bacterial infections. However, current methods for investigating bacterial antibiotic response and metabolic state are time-consuming and lack accuracy.

The global distribution of diet breadth in insect herbivores.

Understanding variation in resource specialization is important for progress on issues that include coevolution, community assembly, ecosystem processes, and the latitudinal gradient of species richness. Herbivorous insects are useful models for studying resource specialization, and the interaction between plants and herbivorous insects is one of the most common and consequential ecological associations on the planet. However, uncertainty persists regarding fundamental features of herbivore diet breadth, including its relationship to latitude and plant species richness.

Prevalence of chronic venous disorders among employees working in prolonged sitting and standing postures.

Research was conducted to determine the prevalence and severity of chronic venous disorders (CVD) among people working in prolonged sitting or static standing postures. Clinical examination and duplex Doppler sonography were performed on 126 employees working in a sitting (96 individuals) or a standing posture (30 individuals). Evidence of CVD was found in 59.

Assessing possible visitor-use impacts on water quality in Yosemite National Park, California.

There is concern that visitor-use associated activities, such as bathing, dish washing, wastewater production, and stock animal use near lakes and streams, could cause degradation of water quality in Yosemite National Park. A study was conducted during 2004-2007 to assess patterns in nutrient and Escherichia coli (E. coli) concentrations in the Merced and Tuolumne Rivers and characterize natural background concentrations of nutrients in the park.

Postpartum endoanal ultrasound findings in primiparous women after vaginal delivery.

Background: Natural childbirth is regarded as the most frequent cause of anal sphincter defects. The majority of obstetric injuries are detectable only by anal endosonography (AES), in from 6.8% to 35% of women after vaginal delivery.

Anal endosonographic findings in women after vaginal delivery.

Objective: To estimate a frequency of obstetric anal sphincters defects in women after vaginal delivery.

Methods: The study included 102 women, aged from 16 to 40 years (mean age 28.6 years).

DECtalk and VeriVox: intelligibility, likeability, and rate preference differences for four listener groups.

The intelligibility, likeability, and speech presentation rates for two types of popular synthesized speech, DECtalk and VeriVox, were investigated across four age groups ranging from 6-85 years old. Results for all age groups revealed differences in intelligibility between synthesized adult and child voices, with intelligibility scores for child synthesized voices significantly below those for adult synthesized voices. The most popular synthesized voices were from the VeriVox family.

Comparison of contrast-enhanced with non-contrast endosonography in the diagnostics of anal fistulas.

The objective of this paper is to compare the accuracy of standard, non-contrast endosonography (EAS) with contrast-enhanced endosonography (CE-EAS) in the diagnosis of anal fistulas. The group consisted of 126 patients (mean age: 43.1 years) with the clinical diagnosis of anal fistula.

[Usefulness of endosonography in patients with colostomy before decision of decolostomy].

The aim of this study was to visualize the suspected defects of the anal sphincters in patients following colostomy by anal ultrasound (AUS) and to analyze possible factors that could have led to such defects. For AUS, Bruel & Kjaer scanner with 7.0 MHz endorectal probe was used in a group of 30 patients with a colostomy.
