Muscle mass, muscle strength and the renin-angiotensin system
Authors: Takeshita Hikari , Yamamoto Koichi , Mogi Masaki , Rakugi Hiromi
Published: December 2024

The renin-angiotensin system (RAS) is a classically known circulatory regulatory system. In addition to the previously known multi-organ circulatory form of the RAS, the existence of tissue RASs in individual organs has been well established. Skeletal muscle has also been identified as an organ with a distinct RAS. In recent years, the effects of RAS activation on skeletal muscle have been elucidated from several perspectives: differences in motor function due to genetic polymorphisms of RAS components, skeletal muscle dysfunction under conditions of excessive RAS activation such as heart failure, and the effects of the use of RAS inhibitors on muscle strength. In addition, the concept of the RAS itself has recently been expanded with the discovery of a ‘protective arm’ of the RAS formed by factors such as angiotensin-converting enzyme 2 and angiotensin 1-7. This has led to a new understanding of the physiological function of the RAS in skeletal muscle. This review summarizes the diverse physiological functions of the RAS in skeletal muscle and considers the potential of future therapeutic strategies targeting the RAS to overcome problems such as sarcopenia and muscle weakness associated with chronic disease.
Interference mitigation method for LEO satellites with optimal dynamic switching array elements in co‐frequency beams
Authors: Wang Haiwang , Huang Chenguang , Zou Cheng , Shao Fengwei , Li Guotong
Published: December 2024

Satellite communication has rapidly advanced, from navigation to broadband Internet and direct mobile connectivity. Driven by low Earth orbit satellites, these networks are merging with terrestrial mobile networks, forming integrated space–air–ground systems. However, the growing scale of satellite constellations has intensified intra‐system interference, particularly among ground cells utilizing co‐frequency beams. A mitigation method based on switching array elements is proposed, optimizing their state by considering beamwidth and maximum sidelobe level. Simulations show that the proposed algorithm effectively reduces beam coverage widening and sidelobes, mitigating the interference between co‐frequency beams.

Authors: Gao Junguo , Liu Liwei , Zhang Guangwei , Lee Tingtai , Schachtely Uwe , Kobayashi Hitoshi
Published: December 2024

To guarantee the reliability of high‐performance and environmentally friendly novel polypropylene (PP) for use as the primary insulation in cables, an assessment of the electrical ageing life of SiO2/PP composite materials was carried out using a step‐stress accelerated ageing test based on the inverse power law. The study involved an analysis of microstructural characteristics and performance testing to investigate the bonding between the SiO2 under different surface treatment methods and matrixes. Furthermore, the impact of SiO2 on charge capture performance in PP insulation was analysed through polarisation–depolarisation current testing. The results show that silica with long alkane chains and amino groups grafted on the surface has good compatibility with PP insulating layers, which can increase the trap energy level of captured electrons and thus reduce the damage of high‐energy electrons to the composites. SiO2 increased the life index of the PP insulating layer by 19.95%, which contributed to the improvement of the electrical ageing life of the PP insulating layer.
1‐Bit reconfigurable reflectarray antenna with T‐shaped parasitic structure
Authors: Li Sen , Cai Yang , Ma Hong , Bu Lijun , Qi Siyu , Cao Yufan , Wu Tao
Published: December 2024

In this paper, an electronically 1‐bit reconfigurable reflectarray antenna (RRA) with wide‐angle beam‐scanning and high efficiency performance is presented for formation satellite communication applications. A 1‐bit phase distribution can be generated by controlling the state of the PIN dipole in the configurable element comprising a double split ring (DSR) patch and two T‐shaped parasitic structures. The resonant frequency of the DSR patch in both states can be optimised by a T‐shaped parasitic structure, which is beneficial to improving the bandwidth and aperture efficiency. A 180° ± 20° phase difference can be realised from 9.7 to 10.3 GHz only by controlling one PIN dipole loaded on the proposed element, which ensures stable radiation performance over a larger band. To validate the effectiveness of the proposed element, a prototype RRA containing 20 × 20 units is designed and measured. A ±60° beam scanning range with the gain drop of 3.2 and 3.3 dB in the xoz and yoz planes is realised, which verifies the wide‐angle beam‐scanning ability of the RRA. The measured peak gain is 25 dBi at 10 GHz in the broadside direction, corresponding to an aperture efficiency of 25.2%. Meanwhile, the 1‐dB gain bandwidth of the proposed RRA is 12.6%.

Published: December 2024

This paper demonstrates a miniaturised frequency selective rasorber (FSR) that incorporates meander cross‐rings to realise a wide transmission band. The FSR comprises a resistive layer and a bandpass frequency selective surface (FSS), which are separated by an air layer. The resistive layer is constructed by employing meander cross‐rings equipped with lumped resistances, where the inner arms of cross‐rings are bent to obtain a parallel resonant circuit with large inductances and small capacitances to achieve broadband transmission at high frequencies. The bandpass FSS is implemented using a triple‐layer metallic structure, where two identical square ring layers are coupled through a central metal grid layer to form the transmission band. The measured results indicate that the absorption band with absorptance exceeding 90% is from 3.5 to 9.4 GHz, and the passband exhibiting insertion loss of less than 1 dB spans from 11.92 to 17.98 GHz with a 40.5% relative bandwidth, which matches well with simulated ones. This FSR has the characteristics of simple structure and high performance, which provides a novel concept of stealth applications.

Published: December 2024

This study assesses the technical, economic, and environmental assessment of a developed improved cookstove (ICS) for domestic uses focusing on outperforming the traditional charcoal cookstove by improving technical performance, fuel economy, and environmental savings. A set of experiments were conducted to verify the performance of the ICS. The technical performance involved measuring the cooking time (tc), maximum cooking temperature (Tmax), fuel consumption (fcons), thermal efficiency (ηth), and cooling time (tcool). The economic assessment involved daily and annual fuel cost, and daily and annual fuel cost saving while environmental saving involved annual reduction of CO, CO2, NO, and NOx gases. The Tmax of the ICS reached 1273 K, reducing the tc by 18 mins, a drop of 43%. Furthermore, this reduced the fcons by approximately 50 g, around 30%. The ICS had an enhanced tcool of about 24.53 mins and attained ηth of 43.3%. In five tests, the ICS consumed about 596 g, which costs TZS 870 and TZS 317,550 per year. The reduction in consumption significantly reduces fuel costs by 29.83%. The results showed the ICS reduced the emission of CO, CO2, NO, and NOx concentrations by 258, 650, 2, and 2.5 ppm, respectively, compared to a traditional charcoal cookstove.
Flow matching for atmospheric retrieval of exoplanets: Where reliability meets adaptive noise levels
Authors: Gebhard Timothy D. , Wildberger Jonas , Dax Maximilian , Kofler Annalena , Angerhausen Daniel , Quanz Sascha P. , Schölkopf Bernhard
Published: December 2024

Context. Inferring atmospheric properties of exoplanets from observed spectra is key to understanding their formation, evolution, and habitability. Since traditional Bayesian approaches to atmospheric retrieval (e.g., nested sampling) are computationally expensive, a growing number of machine learning (ML) methods such as neural posterior estimation (NPE) have been proposed.

Aims. We seek to make ML-based atmospheric retrieval (1) more reliable and accurate with verified results, and (2) more flexible with respect to the underlying neural networks and the choice of the assumed noise models.

Methods. First, we adopted flow matching posterior estimation (FMPE) as a new ML approach to atmospheric retrieval. FMPE maintains many advantages of NPE, but provides greater architectural flexibility and scalability. Second, we used importance sampling (IS) to verify and correct ML results, and to compute an estimate of the Bayesian evidence. Third, we conditioned our ML models on the assumed noise level of a spectrum (i.e., error bars), and thus made them adaptable to different noise models.

Results. Both our noise-level-conditional FMPE and NPE models perform on a par with nested sampling across a range of noise levels when tested on simulated data. FMPE trains about three times faster than NPE and yields higher IS efficiencies. IS successfully corrects inaccurate ML results, identifies model failures via low efficiencies, and provides accurate estimates of the Bayesian evidence.

Conclusions. FMPE is a powerful alternative to NPE for fast, amortized, and parallelizable atmospheric retrieval. IS can verify results, helping to build confidence in ML-based approaches, while also facilitating model comparison via the evidence ratio. Noise level conditioning allows design studies for future instruments to be scaled up; for example, in terms of the range of signal-to-noise ratios.
Flaring together: A preferred angular separation between sympathetic flares on the Sun
Authors: Guité L.-S. , Strugarek A. , Charbonneau P.
Published: December 2024

Context. Sympathetic solar flares are eruptions that occur nearby in space and time, driven by an apparent interaction between the active regions in which they are triggered. Their statistical existence on the Sun has yet to be firmly established.

Aims. The main goal of this paper is to identify a statistical signature of sympathetic flares, characterize their properties, and determine a potential mechanism driving their interaction.

Methods. We performed a statistical analysis of a large number of flares observed by the Atmospheric Imaging Assembly (AIA) on board the Solar Dynamics Observatory (SDO), the Reuven Ramaty High Energy Solar Spectroscopic Imager (RHESSI), and the Spectrometer Telescope for Imaging X-rays (STIX) on Solar Orbiter during solar cycle 24 and 25. We examined the spatiotemporal distribution of consecutive flare pairs across solar cycle phases and hemispheres along with the propagation velocity of potential causal interactions and the relationship between flare magnitudes.

Results. We observed an excess of hemispheric flares separated by about 30° of longitude and triggered in less than 1.5 hours from each other. This peak in angular separation varies with the solar cycle phase and hemisphere. Moreover, we identified a deficit of transequatorial events separated by 25−30° in latitude and less than 5° in longitude, a phenomenon we term unsympathetic flares.

Conclusions. We provide strong statistical evidence for the existence of sympathetic flares on the Sun, demonstrating that their occurrence rate reaches approximately 5% across the three instruments used in this study. Additionally, we propose an interpretation of the observed angular scale of the sympathetic phenomenon based on the separation between magnetic field line footpoints derived from potential field source surface extrapolations.

Published: December 2024

This work is dedicated to conducting a comprehensive analysis of a wheat dataset to identify significant attributes for accurate grain classification. The initial dataset contains various parameters of wheat grains, such as length, perimeter, area, compactness, and asymmetry coefficient. The focus of the study is on analyzing the relationships between these attributes and their impact on the classification target field. Initially, data normalization was performed to eliminate the influence of scale differences between variables. This was followed by a correlation analysis, which revealed several key relationships between attributes. Specifically, it was found that the asymmetry coefficient has a moderate positive correlation with the classification target, while the attributes area, compactness, perimeter, and width exhibit a moderate negative correlation. Length, on the other hand, shows a weak negative correlation with the target attribute. To gain a deeper understanding of the data structure, Kohonen Self-Organizing Maps were used, which helped to identify three clusters. The analysis revealed that the most significant attributes for clustering are compactness, width, perimeter, and area, while the asymmetry coefficient was found to be the least significant. In conclusion, two classification models were built and evaluated. The first model included all attributes from the dataset and demonstrated an accuracy of 0.97. The second model used a subset of attributes excluding the asymmetry coefficient and showed a slightly higher accuracy of 0.98. These results confirm that excluding less significant attributes can lead to a minor but noticeable improvement in model accuracy. Overall, the work highlights the importance of selecting the right attributes to enhance the effectiveness of classification models.

Present the results of many years of development on the effective use of irrigated arable land and water resources in conditions of water shortage. At the same time, a decrease in rice content to 40% and the saturation of the crop rotation wedge with other upland grain crops leads to the gradual use of arable land up to 120% and the grain size increases to 80% relative to the opposite scheme. Reducing rice content by up to 40% on medium loamy soils, with the rice irrigation rate recommended for this zone, allows saving about 25-27% of irrigation water. The use of the recommended technology ensures an increase in rice yield within the range of 11.2 centners, winter wheat - 11.3 centners/ha. The sorghum crop additionally introduced into the scheme provided 66.4 c/ha of yield. Thanks to drip irrigation, when re-seeding after winter wheat, 24.0 tons/ha of potato yield was obtained, when using conventional technology 12.5 tons/ha were obtained. At the same time, the savings in irrigation water amounted to 50- 55%, in addition, the use of expensive mineral fertilizers was reduced by 35- 40% and plant protection products by 25-30%. Thus, in the conditions of the Republic of Karakalpakstan, the introduction of a drip irrigation system that supplies plants in accordance with their water consumption is a relevant and modern approach to the issues of saving natural resources, creating optimal water and nutrient regimes in the root layer of the soil, obtaining an early and high-quality harvest of agricultural crops, automation of irrigation processes, preservation of soil fertility and mitigation of the environmental situation of the region.

Published: December 2024

This article presents an analysis of the calculation of the distribution of river flow in the irrigation system by depth of flow. These studies aim to understand the dynamics of river flows and the impact of irrigation, with researchers dedicating years to this endeavor . In the clarifiers, the larger and medium fractions of sediments should be retained in such quantities that they cannot be transported by the downstream channels. In this case, it is not allowed to re-cool the water in the clarifier, as this will cause the channels in the system to be washed and reduce the fine particles that will increase the productivity of the fields It is known that many scientific studies have been conducted on the depth of river flows. In this case, we will analyze the distribution of river sediments along the depth of the current, using the proposed formulas for calculation. Furthermore, research has demonstrated that the distribution of river flows by depth follows a linear pattern with increasing flow rate or a higher percentage of smaller fractions in suspended particle composition. This distribution characteristic has been observed in various related studies. The practical and scientific findings of these studies are exemplified through research conducted at the “Ekin-Tekin Pumping Station” in the Andijan region, serving as a significant case study in this field. We chose the “Ekin-Tekin pumping station„ located in the Andijan region, as the object of research, and calculated the distribution of turbidity of the river at this pumping station depending on the depth of the flow.

Published: December 2024

In order to provide a basis for the design of the mechanical harvesting parts for pulling carrot, and to obtain the best carrot leaf fruit separation effect, the mechanical properties of carrot leaf were tested. The mechanical properties of carrot leaf were tested by tensile test using a universal testing machine. The tensile strength of the carrot leaf fruit bonding part, primary carrot leaf and secondary carrot leaf were tested, and the influence of different load characteristics, different holding methods and different holding forces on the mechanical properties of carrot leaf were analyzed. The results show that under the combined action of load rate and tensile speed, the tensile strength of the carrot leaf fruit bonding part is (1.27±0.2) MPa, the tensile strength of primary carrot leaf is (5.38±0.71) MPa, and the tensile strength of secondary carrot leaf is (3.11±0.48) MPa. The tensile strength of the carrot leaf fruit bonding part is the smallest, and the carrot will only separate at the bonding part when pulled. When holding, the flexible conveyor belt causes less damage to the carrot leaf than the rigid conveyor chain. When harvesting carrots by pulling, it is only suitable to hold the carrot leaf with a flexible conveyor belt, and the carrot leaf fruit separation effect is good and the efficiency is high when pulling the carrot at a constant speed of 400mm/min.
Women’s development organisations in rural areas of Tunisia: rethinking support to strengthen their autonomy
Authors: Hanafi Anissa , Mazhoud Houda , Chemak Fraj , Faysse Nicolas , Kharroubi Fatma
Published: December 2024

Women’s development organisations in rural areas of Tunisia were first created in the early 2010s, since when their number has increased steadily. These organisations have received wide-ranging support from public and non-governmental development actors, which has helped them develop but has also compromised their autonomy, i.e. their capacity to fix objectives on their own and to contact other actors only when needed to achieve their objectives. The present study analyses the development trajectory and autonomy of women’s development organisations in Siliana Governorate. Most of the activities of the nine organisations studied concern the collective production and marketing of a variety of products related to animal breeding, food, and handicrafts. Since their creation, most organisations have increased their number of members and their range of activities. In a workshop in which presidents of these organisations, their members, and administrative support staff took part, participants pointed out that the members’ technical and management skills, their willingness and ability to organise collective action play a key role in ensuring the autonomy of the organisations. Analysing the autonomy of women’s development organisations − particularly in close collaboration with their members − is a complementary approach to the one focused on solving the often-material constraints that hamper their development. This complementary approach will help focus on how to strengthen their capacity to be in the driver’s seat in defining their goals and strategies and to become fully-fledged partners of support organisations.
Modeling Fibrous Dysplasia Progression and its Therapeutic Intervention
Authors: Beltran-Vargas Juan C. , de Castro Luis F. , Calvo Gabriel F. , Pérez-García Víctor M.
Published: December 2024

Fibrous dysplasia (FD) is a rare, benign bone disorder characterized by the abnormal formation of tissue in a mosaic distribution. It can affect multiple bones, causing severe symptoms such as pathological fractures, spinal curvature, and reduced stature, as part of the so-called McCune–Albright Syndrome (MAS). FD originates from postzygotic gain-of-function mutations in the GNAS gene. While treatments for other skeletal diseases like the monoclonal antibody denosumab, used in osteoporosis, have been applied to FD, the absence of a quantitative understanding of the dynamics of lesional cell populations limits both in-depth analysis and therapy optimization. This study introduces a novel pharmacokinetic–pharmacodynamic mathematical model specifically designed for FD, enriched with in vitro/ex vivo data from denosumab assays. Our framework builds upon existing mathematical approaches for osteoporosis, focusing on two cell populations: (1) variant-bearing FD osteoprogenitors and (2) wild-type (WT) osteoprogenitors displaying transferred FD phenotypes. The resulting model paves the way for future in vitro assays targeting FD and related skeletal conditions. Our analyses reveal that abnormal cell proliferation in FD may be due to its atypical inhibition, providing new insights for potential treatment strategies. Furthermore, our simulations identify a promising biomarker for FD diagnosis.
Quels traitements progestatifs utiliser
chez la jument subfertile
Authors: Allard Aurélie
Published: December 2024

L’article propose une synthèse des études publiées à propos de l’action de l’altrénogest sur la gestation et des recommandations pour un usage raisonné des traitements progestatifs chez la jument subfertile.

Il est largement démontré que seuls l’altrénogest et la progestérone en suspension huileuse permettent le maintien de la gestation chez la jument.

Chez les juments âgées, le traitement par l’altrénogest augmenterait la taille des embryons/fœtus entre 30 et 45 jours, période critique correspondant à l’achèvement de l’organogenèse et le début de la placentation.

En pratique, une supplémentation avec des progestatifs est mise en place chez la jument gravide en cas d’endotoxémie ou lors d’injection accidentelle de prostaglandines, si des signes annonciateurs de perte embryonnaire précoce sont observés ou si la progestéronémie est inférieure à 12,8 nmol/L.

Il est alors recommandé de multiplier les examens échographiques de suivi de gestation chez les juments sous traitement.

Safety is a critical consideration in the oil mill industry, particularly in the context of solvent extraction processes. This study focuses on the safety concerns associated with various solvents used in oil extraction, highlighting the potential risks to workers and end consumers, as well as environmental impacts. The analysis reveals that alcohols, such as ethanol and isopropanol, generally offer better safety profiles compared to hexane, despite presenting higher risks in terms of ATEX (explosive atmosphere) considerations at ambient temperature. These alcohols have higher electrical conductivity, which reduces the risk of electrostatic charge accumulation and subsequent ignition. However, methanol stands out as particularly hazardous due to its wide explosivity range and low minimum ignition energy. Ketones, including acetone and methyl ethyl ketone (MEK), and ethyl acetate also show relatively favourable safety characteristics. These solvents exhibit good electrical conductivity and lower toxicity levels, making them safer alternatives to hexane. Ethyl acetate and MEK are particularly noted for their compatibility with existing safety protocols and equipment. On the other hand, methanol, hexane, and dichloromethane (DCM) rank poorly in multi-criteria safety comparisons. Methanol, DCM and hexanes are presenting specific toxicities making these solvents less desirable from a safety perspective. 2-Methyloxolane (2-MeOx) occupies an intermediate position, with some improvements over hexane but challenges related to its low water miscibility and potential for peroxide formation. The study concludes that while no single solvent is superior across all safety criteria, alcohols and certain ketones could present promising alternatives to hexane if safety was the dominant criteria of selection. In an holistic approach, the possible improvements in safety brought by these solvent must be balanced by their impacts on other criteria like energy consumption, products quality, and economic affordability.
La professionnalisation des arbitres internationaux de tennis des années 1960 à nos jours : entre initiatives françaises individuelles et institutionnalisation par les instances fédérales

L’écosystème arbitral demeure inexploré et peu investigué, notamment dans le milieu tennistique, au sein duquel les officiels sont longtemps restés des amateurs passionnés de l’ombre. Pourtant, l’analyse de la presse spécialisée et des rares ouvrages rédigés par les intéressés eux-mêmes, couplée à des entretiens semi-directifs réalisés auprès d’anciens et d’actuels arbitres internationaux nous permet d’entrevoir historiquement la structuration de ce milieu parallèlement à l’augmentation des enjeux économiques et médiatiques apportés par l’entrée dans l’ère Open en 1968. Nous observons alors l’arrivée de badges internationaux dans en 1979 dont certains officiels français à l’instar de Patrick Flodrops et de Michel Perrot seront parmi les premiers lauréats, contribuant à hiérarchiser un milieu qui se professionnalisera ensuite comme l’expose la carrière annonciatrice de Bruno Rebeuh auprès de la fédération internationale de tennis (ITF). Depuis et dans le sillage d’une massification des évènements internationaux organisés par l’ITF, l’ATP et la WTA qui dirigent désormais le tennis dans le monde entier, le nombre d’officiels français sur l’échiquier international explose dès les années 1990 pour se structurer davantage encore et se professionnaliser dans les années 2000 dès l’échelle fédérale de telle sorte à asseoir définitivement une domination française revendiquée.
The Surgical Management of the Eye in Facial Palsy

Published: December 2024

The surgical management of the periocular region in facial palsy is a critical aspect of addressing the ocular morbidity associated with facial paralysis. The reconstruction around the eye in facial palsy should take into account the duration of the facial palsy and underlying ocular pathologies. Exposure keratopathy can develop secondary to lagophthalmos, ectropion, and brow ptosis. Clinicians should optimize the function of the eye with medical treatments in the first instance and where required adjunctive static or dynamic surgical therapy. The cosmesis of the periocular region should also be taken into consideration when surgical reconstruction is being planned. This manuscript aims to provide a review of surgical solutions for patients with chronic eye manifestations of facial palsy.

Objective Studies on the effects of coronavirus disease 2019 (COVID-19) on pregnant mothers and their newborns, specifically in relation to their micronutrient status, fatty acids (FAs), and inflammatory status are sparse. We hypothesized that COVID-19 infection would adversely affect the transfer of nutrients, and FAs from mothers to their fetuses via the umbilical cord and maternal–fetal distribution of inflammatory cells. This study aimed to determine the effect of COVID-19 on micronutrients, inflammatory markers, and FAs profiles in pregnant mothers and their newborns' cord blood.

Study Design This was a cross-sectional study of 212 pregnant mothers in the third trimester and their newborns, recruited after testing for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) serostatus. Peripheral blood of mothers and cord blood were collected at birth and analyzed for vitamin B12 (Vit B12), folic acid, 25(OH)D3, FAs, and peripheral blood mononuclear cells. Student's t-test or analysis of variance (ANOVA) was used to express statistical significance. Non-normal data were tested using the Mann–Whitney U test and Kruskal–Wallis test, with proportions compared with the chi-square test.

Results Vit B12 levels were significantly low and adrenic acid levels significantly high in COVID-19 seropositive mothers while 25(OH)D3 was significantly low in seropositive cord blood. Irrespective of COVID-19 serostatus, folate, vit B12, saturated FA levels were significantly high in cord blood indicating their increased transfer from mothers to the fetus. However, monounsaturated (MUFA) and polyunsaturated fatty acid (PUFA) levels were significantly lower in cord blood. Irrespective of COVID-19 serostatus, CD4+ T helper cells (percentage of lymphocytes) were significantly higher in cord blood, while NK cells, NK-T cells, and CD8+ T-cytotoxic cells—percentage of lymphocytes—were significantly lower in cord blood when compared with corresponding mother's blood.

Conclusion The results indicate that while COVID-19 did not impede the transfer of essential nutrients such as MUFA and PUFA from mother to fetus, or affect maternal–fetal immune cell responses, it did appear to affect the levels of vit B12, vitamin D, and adrenic acid.

Objective This study analyzed the relationship between clinical parameters and prognosis in children with Mycoplasma pneumoniae (MP)-positive lobar pneumonia and developed an early identification model.

Methods Relevant clinical parameters were collected. Patients were then categorized into two groups based on their length of hospital stay: 116 cases in the refractory group (≥10 days) and 94 cases in the non-refractory group (<10 days). A univariate analysis of variance and binary logistic regression were utilized to develop a predictive model, accompanied by the construction of a nomogram. The model's performance was assessed using receiver operating characteristic (ROC) curves, diagnostic calibration curves, and decision curve analysis (DCA) curves. Furthermore, clinical data from 100 additional cases of MP-positive lobar pneumonia in children treated at other centers were gathered for external validation of the model.

Results Binary logistic regression analysis identified four independent risk factors for prolonged disease duration in children with MP-positive lobar pneumonia: erythrocyte sedimentation rate (ESR), globulin, lactate dehydrogenase (LDH), and SF. We constructed a nomogram model based on these risk factors. In the training set, the area under the curve (AUC) was 0.869 (95% CI: 0.822–0.917), with a sensitivity of 68.54% and a specificity of 82.61%. For the test set, the AUC increased to 0.918 (95% CI: 0.866–0.971), demonstrating a sensitivity of 91.67% and a specificity of 78.69%. The DeLong test results indicated that the difference in AUC between the two datasets was not statistically significant (D = − 1.724, p = 0.086). Calibration curve analysis confirmed that the nomogram model exhibited a good fit in both the training set (Hosmer–Lemeshow test, χ2 = 8.120, p = 0.421) and the validation set (Hosmer–Lemeshow test, χ2 = 14.601, p = 0.067). DCA further demonstrated that the model performed significantly across a range of threshold probabilities.

Conclusion The nomogram model developed for predicting refractory MP-positive lobar pneumonia in children has significant clinical value and can guide personalized treatment strategies.

Published: December 2024

Survival into adulthood in patients with an interrupted aortic arch (IAA) is exceedingly rare. A recent literature review found 25 reported cases of IAA in adults. We describe the first case of prolonged, occult, postoperative gastrointestinal bleeding as a major complication following IAA surgery. We discuss the management of a 51-year-old man who underwent repair of an IAA, aortic valve replacement, and replacement of the ascending aorta for a known aortic aneurysm.
Effect of nonequilibrium phenomena in a superconducting point contact on the properties of a single-contact quantum interferometer
Authors: Khlus V. A.
Published: December 2024

The behavior of a superconducting ring incorporating a point contact, coupled inductively to an oscillatory circuit (hf SQUID), with the rate of change of the magnetic flux in the ring being comparable, to the inverse energy relaxation time of excitations in the superconductor τϵ−1, is examined. For T ∽ Tc the results of the microscopic theory of the nonstationary behavior of point contacts, in which the coupling between the phase difference and the current of the Josephson junction differs from the usual expression I = V/R + Icsinφ in the resistive model, are used. It is shown that the nonequilibrium behavior of a weak link for ω≳τϵ−1 significantly changes the amplitude–frequency and signal characteristics of the SQUID as compared with the case ωτϵ−1≪1, for which the results based on the resistive model are valid. The characteristics of the SQUID in the nonequilibrium situation are sensitive to the ratio between the size of the contact and the mean free path of electrons relative to scattering by impurities.
