Published: August 2024

Для мониторинга объектов техногенного происхождения рассмотрены вопросы уменьшения погрешности наведения оптико-электронной системы (ОЭС) обзора космического пространства на объект. Эта погрешность возникает вследствие воздействия механических факторов на конструкцию опорно-поворотного устройства. Для уменьшения этих погрешностей применяются калибровка оптических датчиков ОЭС по звездам, математические методы обработки измерений, повышающие их точность, или интерполяционные методы для определения промежуточных значений между измеренными калибровочными точками. С помощью сплайн-аппроксимации найдены поправки к показаниям оптических датчиков азимутальной и угломестной оси. Полученные результаты могут использоваться в комплексах ОЭС, следящих за космическими объектами, и позволят повысить точность их наведения.
To monitor objects of man-made origin, the issues of reducing the errors of pointing an optoelectronic system (OES) of a space survey at an object, which are associated with the influence of mechanical factors on the design of a pivoting device, are considered. To reduce these errors, the calibration of the optical sensors of the OES by stars is used. Mathematical methods of processing measurements are used to increase their accuracy, or interpolation methods are used to determine intermediate values between measured calibration points. The work uses spline approximation to find corrections to the readings of optical sensors of the azimuthal and elevation axes.

Вулкан Эребус является самым южным действующим вулканом на Земле, в состав выбросов которого входят соединения, играющие существенную роль в каталитических циклах разрушения стратосферного озона. Высокие циклоны способствуют подъему газовых выбросов вулкана Эребус (включая HСl и SO2) из тропосферы в высотный диапазон формирования озоновой дыры от 14 до 22 км. Рассмотрено интегральное содержание HCl и ClONO2за 1992–2023 гг. над разными станциями, а также проведен анализ изменчивости частоты появления высоких циклонов над вулканом Эребус за 1980–2022 гг. по данным реанализа ERA5. Выявлено, что максимальная частота появления высоких циклонов над вулканом Эребус, как правило, наблюдается в июле. Анализ интегрального содержания HCl на разных станциях показал, что значения над Антарктикой значительно превышают таковые над Арктикой, а также почти в два раза выше, чем на станциях, расположенных в средних широтах. Показан предполагаемый эффект накопления HCl в стратосфере: коэффициент корреляции между пятилетними средними значениями частоты появления высоких циклонов и площади озоновой дыры с временным сдвигом ряда на четыре года вперед относительно ряда частоты появления высоких циклонов, рассчитанный с 1980 по 2022 г., составил 0,78. Полученные результаты могут быть использованы для более точного прогнозирования и моделирования изменений в атмосфере, связанных с деятельностью вулканов.
Erebus volcano is the southernmost active volcano on Earth, whose volcanogenic emissions include components that play a significant role in catalytic cycles of stratospheric ozone depletion. High cyclones contribute to the rise of gas emissions from Erebus volcano (including HCl and SO2) from the troposphere to the altitudinal range of ozone hole formation, from 14 to 22 km in the stratosphere. The paper considers the integral content of HCl and ClONO2for the period 1992–2023 and analyzes the variability of the frequency of high cyclone occurrence for the period 1980–2022 based on the ERA5 reanalysis data. It is revealed that the maximal frequency of occurrence of high cyclones over Erebus volcano is usually observed in July. The analysis of the integrated HCl content at different stations showed that the values over the Antarctic are much higher than over the Arctic and approximately twice as high as at midlatitude stations. The effect of HCl accumulation in the stratosphere is shown: the correlation coefficient between 5-year average frequencies of occurrence of high cyclones and 5-year average values of ozone hole area with a 4-year shift of the series of the ozone hole area ahead relative to the series of the frequency of occurrence of high cyclones, calculated for the period from 1980 to 2022, amounts 0.78.

Published: August 2024

BACKGROUND AND OBJECTIVES
The lack of provision of culturally and linguistically appropriate services (CLAS) to families with languages other than English (LOE) is a highly modifiable driver of health care inequities. In a nationally representative sample of level 2 to 4 US NICUs, we examined patterns and predictors of communication practices for families with LOE and ascertained clinical leaders’ beliefs about barriers to CLAS provision.

METHODS
We surveyed clinical leaders from 500 randomly selected US NICUs. Responses were weighted by the number of eligible NICUs per region and nonresponse rates. Outcomes included: consistent parental language documentation (≥75% of the time versus &lt;75%) and consistent professional interpreter use (in-person or remote interpretation ≥75% of the time versus &lt;75%). We used logistic regression to examine the associations of predictors (region, hospital characteristics, and the proportion of racial and ethnic minority and families with LOE served) with outcomes.

RESULTS
The overall response rate was 34%. A total of 63% of NICUs collected parental language data consistently, and 41% used interpreters consistently. Patterns of interpreter use varied by service hours and type of communication event. Teaching status, highest level of neonatal care, and larger NICU size were associated with consistent language documentation. Only a larger NICU size was associated with consistent interpreter use. Barriers to CLAS provision included untimely access to interpreter services and suboptimal quality of certain interpretation modalities.

CONCLUSIONS
Implementation guidance, accountability for compliance with existing mandates, and interventions tailored to the NICU context are needed to reduce linguistic disparities.

The study’s aim was to investigate the impact of laboratory-imitated digestion, including mouth, gastric, and intestinal phases of olive pomace on the stability, bioaccessibility, and recovery of phenolic compounds as well as antioxidant ability. The total flavonoid content (TFC) and total polyphenol content (TPC) were extracted using water or 50% and 100% methanol, ethanol, and acetone. The digested mixture after each phase of digestion was centrifuged and used to assess recovery, bioaccessibility, and polyphenolic stability. Compared to other solvents, 100% methanol and ethanol extracts showed the highest values of TPC, TFC, half-maximal inhibitory concentration (IC50) of 2,2-diphenyl-1-picrylhydrazyl (DPPH), and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) IC50. The recovery rates of TPC, TFC, DPPH IC50, and ABTS IC50 decreased in a descending order during the gastrointestinal phases as follows: mouth > stomach > intestines. After gastric (27.20%) and intestinal (26.79%) phases, the TPC bioaccessibility index in olive pomace increased significantly, which was statistically similar to the oral phase (21.20%). For TFC, the bioaccessibility rate did not change significantly after mouth and intestinal phases. There were no significant differences in flavonoids and antioxidant scavenging activities among the three phases of digestion. The pellet fractions had higher phenolic levels and better free radical scavenging activity in all phases of digestion than chyme-soluble fractions. TPC or TFC had a significant and positive relationship with Pearson correlation coefficient (r = 0.891–0.994) with DPPH and ABTS scavenging rates in oral, gastric, and intestinal digestion phases. Overall, our research could pave way for the industrial application of olive pomace waste as a possible food ingredient to generate functional foods with beneficial health effects.

Insurance coverage for prenatal care, labor and delivery care, and postpartum care for undocumented immigrants consists of a patchwork of state and federal policies, which varies widely by state. According to federal law, states must provide coverage for labor and delivery through Emergency Medicaid. Various states have additional prenatal and postpartum coverage for undocumented immigrants through policy mechanisms such as the Children’s Health Insurance Program’s “unborn child” option, expansion of Medicaid, and independent state-level mechanisms. Using a search of state Medicaid and federal government websites, we found that 27 states and the District of Columbia provide additional coverage for prenatal care, postpartum care, or both, while 23 states do not. Twelve states include any postpartum coverage; 7 provide coverage for 12 months postpartum. Although information regarding coverage is available publicly online, there exist many barriers to access, such as lack of transparency, lack of availability of information in multiple languages, and incorrect information. More inclusive and easily accessible policies are needed as the first step toward improving maternal health among undocumented immigrants, a population trapped in a complicated web of immigration policy and a maternal health crisis.

Countercurrent Imbibition in Porous Media with Dense and Parallel Microfractures: Numerical and Analytical Study
Authors: Yu Fei , Han Rujun , Xu Ke 
Published: August 2024

SummaryCountercurrent imbibition is the process in which the wetting fluid spontaneously displaces the nonwetting fluid, while the nonwetting fluid is recovered at the wetting fluid inlet. It is a major mechanism for the recovery of shale oil, shale gas, and tight oil. In shale and tight formations, microfractures are highly developed. Specifically, some typical formations, such as continental shales, consist of dense and parallel microfractures (DPFs). In DPF systems, microfractures are segregated by low-permeability matrix layers, while the very close distance betwen neighboring microfractures results in strong capillary correlation. The underlying assumptions of the classical dual-porosity (DP) model break down. Despite extensive studies on layered media, there is still no suitable model to describe imbibition in the DPF system at the representative elementary volume (REV) scale.In this study, we first numerically simulate countercurrent imbibition in DPF systems with fine grids, adopting typical continental shale parameters. For imbibition parallel to microfractures, two distinct stages are identified: an early stage where fractures are not correlated and a late stage where neighboring fractures are strongly correlated by capillarity. In both stages, cumulative oil production (Q) is proportional to the square root of imbibition time (t1/2), while the prefactors are very different. The late stage is the dominant stage in oil recovery. We note that the matrix permeability rarely contributes to imbibition parallel to microfractures at the late time, indicating that the matrix’s role here is to store fluid rather than to provide flow resistance. In addition, we rationalize the failure of the classical DP model, as it significantly overestimates fracture-matrix fluid exchange near the displacement front. Similarly, for imbibition perpendicular to microfractures, Q is also proportional to t1/2 in the late stage.After elucidating the mechanisms of fracture-fracture capillary interaction, we successfully derive analytical solutions for uni-directional countercurrent imbibition kinetics in DPF systems at the late stage, for imbibition parrallel and perpendicular to microfractures, respectively. We accordingly propose an equivalent REV scale model and examine it with fine-grid simulations. We highlight the importance of adopting anisotropic relative permeability in this DPF system at REV scale for reservoir simulation rather than simply adopting anisotropic absolute permeability. This presents a new challenge for numerical simulations at reservoir scale.

Abstract

Aflatoxin M1 (AFM1) is known to be carcinogenic, mutagenic, and teratogenic and poses a serious threat to food safety and human health, which makes its surveillance critical. In this study, an indirect competitive ELISA (icELISA) based on a nanobody (Nb M4) was developed for the sensitive and rapid detection of AFM1 in dairy products. In our previous work, Nb M4 was screened from a Bactrian-camel-immunized phage-displayed library. It exhibits VH-like features, possesses higher thermal stability than monoclonal antibody (mAb 1E6) and tightly binds to AFM1–BSA with a KD value of 2.5 nM. Under the optimal conditions, its half-maximal inhibitory concentration was 0.338 ng/mL, the limit of detection was 0.051 ng/mL, and linearity was noted in the range of 0.168–0.679 ng/mL. Nb M4 displayed almost no cross-reactivity with other mycotoxins. No matrix effect was observed in milk and milk powder samples, and the matrix effect in yogurt samples could be weakened by 2-fold dilution. Furthermore, validation studies in spiked samples (milk, yogurt, and milk powder) resulted in good recoveries of 95.40%–111.33%, with a low coefficient of variation (2.89%–6.78%). High-performance liquid chromatography was used to evaluate the accuracy and reliability of the developed icELISA, which indicated a satisfactory consistent correlation (R2 = 0.9722). This study has provided a novel and ideal strategy for detecting AFM1 in dairy products.

Abstract

Background: Programmed cell death 1/programmed death ligand-1 (PD-L1)-based immune checkpoint blockade is an effective treatment approach for non-small-cell lung cancer (NSCLC). However, immunohistochemistry does not accurately or dynamically reflect PD-L1 expression owing to its spatiotemporal heterogeneity. Herein, we assessed the feasibility of using a 68Ga-labeled anti-PD-L1 nanobody, 68Ga-NODAGA-NM-01, for PET imaging of PD-L1.
Methods: Micro-PET/CT and biodistribution studies were performed on PD-L1-positive and -negative tumor-bearing mice. Additionally, a preliminary clinical study was performed on two patients with NSCLC. NM-01 was radiolabeled with 68Ga without further purification under mild conditions.
Results: 68Ga-NODAGA-NM-01 exhibited radiochemical purity (>98%), high stability in vitro, and rapid blood clearance in vivo. Specific accumulation of 68Ga-NODAGA-NM-01 was observed in PD-L1-positive tumor-bearing mice, with a good tumor-to-background ratio 0.5 h post-injection. Furthermore, 68Ga-NODAGA-NM-01 PET/CT imaging was found to be safe with no adverse events and distinct uptake in primary and metastatic lesions of the PD-L1-positive patient, with a higher maximal standardized uptake value than that in lesions of the PD-L1-negative patient 1 h post-injection.
Conclusions: 68Ga-NODAGA-NM-01 can be prepared using a simple method under mild conditions and reflect PD-L1 expression in primary and metastatic lesions. However, our findings need to be confirmed in a large cohort.
