BackgroundNosocomial transmission of Clostridioides difficile infection (CDI) has been documented in Ningbo, China. However, data on molecular characteristics, clonal transmission, and risk factors of CDI in this region remain limited.MethodsA cross-sectional study enrolled hospitalized patients with diarrhea during September to November 2021. Stool samples from all patients were tested for C. difficile, and isolated strains underwent toxin gene identification, genotyping, and antibiotic susceptibility testing. Whole-genome sequencing and epidemiological variables were analyzed in patients infected with C. difficile strains of the same sequence types (STs) to identify nosocomial transmission and risk factors for CDI.ResultsOf the 907 investigated patients, 115 (12.7%) had microbiologically proven CDI, as their diarrhea was associated with toxigenic C. difficile strains, which comprised 106 A+B+CDT−, 3 A−B+CDT−, and 6 A+B+CDT+. Predominant genotypes (ST2, ST3, ST35, and ST54) exhibited distinct antibiotic resistance patterns. ST54 strains showed higher resistance to erythromycin (100%) but lower resistance to moxifloxacin (18.2%) and gatifloxacin (18.2%) (χ2 = 10.24–16.65, p &lt; 0.05). ST35 strains exhibited higher resistance to ciprofloxacin (66.7%) and tetracycline (33.3%) than other STs (χ2 = 13.30–20.19, p &lt; 0.05). Genomic and epidemiological analysis revealed two nosocomial clonal transmission events caused by 5 ST35 strains (with ≤2 single nucleotide polymorphism differences), elucidating clonal transmission among different floors and buildings within the hospital. Prolonged hospitalization (&gt; 10 days) (odds ratio [95% confidence interval], 1.76 [1.05–2.93]) and penicillin-class antibiotics (1.69 [1.11–2.58]) were risk factors for CDI, with the latter being an independent risk factor (1.57 [1.02–2.42]). For C. difficile ST35 infection, intensive care unit (12.00 [2.77–52.05]) and neurology departments (8.08 [1.46–44.65]) admissions were risk factors, with the latter as an independent risk factor (1.56 [1.01–2.40]).ConclusionMultiple C. difficile genotypes with varied antibiotic resistance patterns circulated in Ningbo, with ST35 causing nosocomial clonal transmission among different floors and buildings within the hospital. These findings and the identified risk factors necessitate enhanced surveillance and infection control in the region.

For a Chevalley group G over an algebraically closed field K of characteristic p>0 with the irreducible root system R, Lusztig’s character formula expresses the formal character of a simple G-module by the formal characters of the Weyl modules and the values of the Kazhdan–Lusztig polynomials at 1. It is known that, for a sufficiently large characteristic p of the field K, Lusztig’s character formula holds. The known lower bound of the characteristic p is much larger than the Coxeter number h of the root system R. Observations show that for simple modules with restricted highest weights of small Chevalley groups such as those of types A1,A2, A3,B2, B3, and C3, Lusztig’s character formula holds for all p≥h. For large Chevalley groups, no other examples are known. In this paper, for G of type Al, we give some series of simple modules for which Lusztig’s character formula holds for all p≥h. Using this result, we compute the cohomology of G with coefficients in these simple modules. To prove the results, Jantzen’s filtration properties for Weyl modules and the properties of Kazhdan–Lusztig polynomials are used.

РАСЧЕТ КОЭФФИЦИЕНТА СЖИМАЕМОСТИ ПРИРОДНОГО ГАЗА В СИСТЕМАХ КОММУНАЛЬНОГО ГАЗОСНАБЖЕНИЯ
Authors: Д.Н. Китаев , О.А. Куцыгина 
Published: December 2024

При определении объемов полученного природного газа потребителем необходимо приведение показаний счетчика к стандартным условиям. При этом необходимо учитывать значение коэффициента сжимаемости природного газа при стандартных и рабочих условиях. Современные справочные данные и рекомендуемое минимальное значение применения уравнений состояния реальных газов ограничено 250К, но на практике фактические значения могут быть значительно ниже. Ошибки при использовании подстановочных значений коэффициента сжимаемости влияют на расчет итоговых объемов природного газа. В статье представлены результаты вычислений коэффициента сжимаемости природного газа расчетного состава по двум уравнениям состояния, учитывающим реальные свойства в диапазоне температур 223,15…303,15 К и давлений 0,1…0,6МПа, применяемых для газоснабжения потребителей жилищно-коммунального комплекса. Предложено уравнение, позволяющее проводить расчеты коэффициента сжимаемости природного газа расчетного состава в зависимости от давления и температуры в рассмотренном диапазоне с высокой точностью.
When determining the volumes of natural gas received by the consumer, it is necessary to bring the meter readings to standard conditions. In this case, it is necessary to take into account the value of the natural gas compressibility factor under standard and operating conditions. Modern reference data and the recommended minimum value for the application of equations of state of real gases is limited to 250K, but in practice, actual values may be significantly lower. Errors in the use of substitute values of the compressibility factor affect the calculation of the final volumes of natural gas. The article presents the results of calculating the compressibility factor of natural gas of the estimated composition using two equations of state that take into account real properties in the temperature range of 223,15…303,15 K and pressures of 0,1…0,6 MPa used for gas supply to consumers of the housing and communal complex. We propose an equation that allows calculating the compressibility factor of natural gas of the estimated composition depending on the pressure and temperature in the considered range with high accuracy.

Published: December 2024

Passer domesticus holds the title of being the most widely distributed bird species globally, originating from Central-East Asia and spreading extensively due to human-mediated activities. While initially established as a native species about 10,000 years ago, their association with human-modified habitats has accelerated their expansion, particularly in urban areas. In Thailand, sightings were initially rare but gradually increased, with the species establishing breeding populations, predominantly in urban and suburban areas. This expansion poses challenges as they compete with native species for resources and nesting sites. This study utilized citizen science data from the eBird platform to investigate the factors influencing the expansion of P. domesticus breeding areas in Thailand. Through occupancy modeling, spatiotemporal patterns of colonization were analyzed, revealing the influence of urbanization, vegetation indices, elevation, and proximity to infrastructure. Results showed a steady increase in territorial occupancy, particularly in urbanized regions, with roads and petrol stations acting as facilitators for dispersal. The study underscores the role of urban expansion in facilitating the spread of P. domesticus, raising concerns about its impact on native bird species and biodiversity in Thailand. Further research is warranted to assess the full extent of its ecological implications and to devise strategies for mitigating its potential adverse effects.
Simulating Self-lensing and Eclipsing Signals due to Detached Compact Objects in the TESS Light Curves
Authors: Sajadian Sedighe , Afshordi Niayesh 
Published: December 2024

Abstract
A fraction of Galactic stars have compact companions that could be white dwarfs (WDs), neutron stars (NSs), or stellar-mass black holes (SBHs). In a detached and edge-on binary system including a main-sequence star and a compact object (denoted by WD main-sequence (WDMS), NS main-sequence (NSMS), and SBH main-sequence (BHMS) systems), the stellar brightness can change periodically due to self-lensing or eclipsing features. The shape of a self-lensing signal is a degenerate function of stellar radius and the compact object’s mass because the self-lensing peak strongly depends on the projected source radius normalized to the Einstein radius. Increasing the inclination angle i changes the self-lensing shape from a strict top-hat model to one with slowly increasing edges. We simulate stellar light curves due to these binary systems that are observed by NASA’s Transiting Exoplanet Survey Satellite (TESS) telescope and evaluate the efficiencies to detect their periodic signatures using two sets of criteria: (i) signal-to-noise ratio (SNR) >3 and N
tran > 1 (low confidence, LC), and (ii) SNR >5 and N
tran > 2 (high confidence, HC). The HC efficiencies for detecting WDMS, NSMS, and BHMS systems with the inclination angle i < 20° during different time spans are 5%–7%, 4.5%–6%, and 4%–5%, respectively. Detecting lensing-induced features is possible in only ≲3% and ≲33% of detectable WDMS and NSMS events. The detection efficiencies for closer source stars with higher priorities are higher and drop to zero for b ≳ R
