Authors: Yan Mingzhu , Wu Jiahui , Jiang Huan , Kou Yang , Zhao Wei 
Published: March 2024

Abstract
The increasing scale of wind power access to the grid makes it important to identify weak links in the system to prevent major outages. In order to analyze the vulnerability of grid nodes, this paper proposes a dynamic comprehensive evaluation method considering system uniformity, and establishes a comprehensive assessment model of node vulnerability based on wind power grid-connectedness, based on which the vulnerability of wind power-containing power systems is studied. Firstly, the improved weighted power entropy index is selected for the phenomena of system current instability and line overloading, and the comprehensive index set of node vulnerability is constructed by considering the structural and state characteristics, and the subjective and objective weights are calculated by using the hierarchical analysis method and the CRITIC method. Subsequently, the Dagum-Gini coefficient method is utilized to reflect the homogeneity of the system, and a comprehensive evaluation method based on the VIKOR method is used to confirm the ordering of critical nodes that have the greatest impact on the system and have a high failure rate. Finally, the proposed method is applied to the study of node vulnerability of wind-containing power systems. The feasibility of the above methodology is verified by a modified IEEE-118 test system with test simulations.

Published: March 2024

Abstract
Free standing nanocomposite polymer electrolytes (NCPEs) based on the polymer host poly(vinyl) chloride (PVC) were successfully prepared using the solution casting technique. Lithium nitrate (LiNO3) and nano-sized silica (SiO2) (< 100 nm) were employed as the electrolyte and filler, respectively. Impedance studies revealed a maximum ionic conductivity value of 1.226 x 10− 4 S/cm at room temperature for the PVC/LiNO3 with 5 wt.% nano-SiO2. X-ray diffraction (XRD) analysis verified the sample's amorphous nature. Dielectric permittivity and relaxation time values were consistent with impedance results. Additionally, parameters such as diffusion coefficient, mobile concentration, and mobility were evaluated for the prepared samples. Differential scanning calorimetry (DSC) studies confirmed a change in glass transition temperature (Tg) of PVC/LiNO3/SiO2 sample. The scanning electron micrograph (SEM) images revealed a honey-comb morphology, indicating ease of Li+ ion transportation.

Published: March 2024

Abstract
The Gompertz model, a mainstay in tumor growth kinetics analysis, requires an accurate likelihood function for its parameterestimation, applicable in both classical and Bayesian methodologies. This study compares five distinct error models, eachrepresenting a different likelihood function. Our comparative analysis employs the Bayesian Information Criterion (BIC), theDeviance Information Criterion (DIC), the Bayes Factor (BF), and hypothesis tests on residuals. Applying these criteria to fitthe Gompertz model to Ehrlich and fibrosarcoma Sa-37 tumor data, we find that error models with tumor volume-dependentdispersion consistently outperform others in quantitative evaluations. However, the conventional Normal error model withconstant variance remains a vital tool, offering significant clinical insights. This study underscores the complexity of likelihoodmodel selection in tumor growth kinetics and highlights the need for a multifaceted approach in such analysis.

Abstract
Spectroscopic studies on isolated domains of large proteins and peptides derived from them are complicated because of their tendency to dissolve in aquatic buffers in form of oligomers. Here we demonstrate that conjugation of such peptides with a carrier protein is helpful for studies on the influence of different factors on their secondary structure. Namely, we approved that SK30 peptide from phospholipase A2 domain of Parvovirus B19 capsid conjugated to BSA through N-terminal Cys residue and SMCC linker undergoes random coil to alpha helix transition in the acidic medium mimicking the environment of endolysosome because of His residue protonation. In contrast, unconjugated peptide does not undergo such shift because it forms stable octamers connected by intermolecular beta sheet, as well as the whole isolated phospholipase domain. Obtained results provide evidence on the mechanism of phospholipase domain folding during the acidification of the medium by the way of the formation of contacts between protonated His153 and Asp175, and opens up a perspective of vaccine development, since rabbit polyclonal antibodies against our conjugate, in which the structure of the second alpha helix from the phospholipase A2 domain has been reproduced, can bind epitopes of the complete unique part of VP1 Parvovirus B19 capsid.
Alteration and Predictive Ability of Cervical Length for Preterm Delivery in Each Gestational Trimester
Authors: Zhang Qidi , Han Xinyue , Yang Huixia , Zhu Yuchun , Wei Yumei 
Published: March 2024

Abstract
Background
To investigate the variations in cervical length (CL) across the first, second and third trimesters and the association with preterm delivery (PTD).
Methods
In total, 16,352 women (32,543 measurements) who delivered singleton live births between January 1, 2020, and October 31, 2023, at Peking University First Hospitals were included in the present study. The associations between CL at three gestational weeks (9–13+ 6, 19–23+ 6 and 29–33+ 6 weeks) and PTD were evaluated using receiver operating characteristic (ROC) curves and logistic regression analysis. The chi-square test was used for comparisons of the incidence of PTD at or below each percentile for CL with patients with CL above the 75th percentile.
Results
With increasing gestational age, there was a downward trend in CL at each percentile, with particularly obvious decreases in the 10th (31.5 mm and 27.1 mm), 5th (30.0 mm and 23.4 mm) and 1st (25.2 mm and 15.5 mm) percentiles after the 19th week of gestation. As gestational age increased, the predictive value of CL for PTD ≤ 34+ 6 gestational weeks and PTD < 37 gestational weeks increased. After the 19th week of gestation, CL and PTD risk were negatively correlated when CL was less than or equal to the 75th percentile (all P < 0.01). The incidence of PTD < 37 gestational weeks was significantly higher among women with CL ≤ 22.3 mm at 29–33+ 6 gestational weeks than among women with CL ≤ 25 mm.
Conclusions
CL progressively decreases with increasing gestational age and has emerged as a more potent predictor of PTD after the 19th week of gestation. The defining threshold of a short cervix should probably be less than 25 mm at 29–33+ 6 gestational weeks.

Abstract
OBJECTIVES: To investigate the predictive value of end-tidal carbon monoxide concentration (ETCOc) within 48 hours after birth in neonatal hyperbilirubinemia caused by hemolysis.
METHODS: A prospective study was conducted on hemolytic high-risk newborns. ETCOc within 24 hours (D1-ETCO) and between 24 to 48 hours after birth (D2-ETCO) were measured. They were divided into a normal group, a nonhemolytic hyperbilirubinemia (NHH) group, and a hemolytic group based on whether they had hyperbilirubinemia or hemolysis.
RESULTS: The hemolytic group had the highest ETCOc values, followed by the NHH group, and the normal group. The AUC of D1-ETCO and D2-ETCO were 0.958 and 0.862. The sensitivity and specificity were 83.3%, 94.7%, 72.0%, and 96.0%, respectively. There was a linear correlation between D1-ETCO and total bilirubin /age at admission ratio and reticulocytes (r = 0.896 and 0.878, respectively).
CONCLUSIONS: ETCOc within 48 hours can predict hyperbilirubinemia caused by hemolysis well.

Abstract
Background Each controlled ovarian hyperstimulation(COH) protocol has its own unique mechanism and hormone pattern. The depot GnRHa protocol has a deeper down-regulation effect and favourable clinical pregnancy rates, the predictive model of the optimal follicle-stimulating hormone (FSH) starting dose in the early follicular phase depot GnRH agonist (EFDGa) protocol has not been reported. Our study was made to explore predictive indicators for determining the optimal FSH starting dose in patients undergoing ovarian stimulation with the EFDGa protocol in assisted reproductive technology (ART), and to develop and validate a nomogram prediction model for the starting dose of FSH.
Methods This retrospective study included 2733 cycles who underwent fresh cycle transplantation at two large teaching hospitals in China from January to December 2022: center 1 (Reproductive Medicine Center of first affiliated Hospital of Zhengzhou University) provided the data for modelling (n = 938) and internal testing (n = 400), and center 2 (Reproductive Medicine Center of Jiangxi Maternal and Child Health Hospital) provided the data for external testing (n = 1109). Patient demographics, including age, anti-Mullerian hormone (AMH) levels, baseline endocrine profile, and body mass index (BMI), along with information on ovulation stimulation, were collected. Univariate and multivariate linear regression models were used to identify factors influencing the FSH starting dose. A nomogram for the ideal FSH starting dose was developed based on these factors and validated internally and externally. Bland and Altman plots and paired t-tests were conducted to verify the concordance and RMSE between groups.
Results Univariate analysis revealed that patient age, BMI, baseline FSH, AMH, and antral follicle count (AFC) were indicators of FSH starting dose. The regression model for predicting FSH starting dose was determined as: Initial dose of FSH = 45.984 + 1.728 * AGE (years) + 5.131 * BMI (kg/m²) + 2.455 * bFSH (IU/ml) - 6.697 * AMH (ng/ml) – 3.339 * AFC. Bland and Altman analysis showed good agreement in the internal validation (bias: 0.629, SD of bias: 36.83, 95%LoA: -71.55 - 72.81 IU). Furthermore, validating the model on external cohort confirmed that nomogram prediction model is an accurate predictor of FSH starting dose ((bias: -1.428, SD of bias: 43.21, 95%LoA: -85.11 - 82.15 IU).
Conclusions We established a model for effectively predicting the ideal FSH starting dose, with the nomogram model providing an intuitive representation of the data. The predictive model demonstrates practical utility, effectively initiating a proper ovarian response and preventing adverse ovarian reactions or the occurrence of ovarian hyperstimulation syndrome. As more IVF cycles are being generated in the future, this model will be valuable in clinicians using basic parameters to assess proper initial dose of FSH.
Feasibility Study of Utilizing Saccharomyces boulardii as an Adjunct Culture in Mozzarella Cheese Making and Quality Characterization of Cheese
Authors: Bihola Ankit , Jana Atanu H. , Parmar Satish C. , Adil Shaikh 
Published: March 2024

Abstract
Research pertained to investigate influence of utilizing Saccharomyces boulardii as an adjunct culture at two levels on the quality aspects of Mozzarella cheese. Two protocols were employed: Protocol I using unhomogenized milk, adopting cheddaring of curd before plasticizing (i.e. CCUM) and Protocol II using blend of homogenized and unhomogenized milks (1:1; i.e. CBHM) to evaluate which method lends led to more S. boulardii count. Control cheese (CUM) was prepared from unhomogenized milk involving stretching of curd, post whey draining. Cheese CBHM4.2 showed the highest yield. The textural properties of cheeses CCUM3.5 and CCUM4.2 as well as CBHM3.5 and CBHM4.2 were at par. CUM and CCUM cheeses had excellent baking properties (viz., shred, melt, fat leakage, stretch), while CBHM demonstrated desirable baking properties. Cheese made using lower level of starter adjunct received higher sensory scores on pizza pie. Using adjunct culture at higher usage level led to cheese having increased S. boulardii and Lactic Acid Bacteria count. It is recommended to adopt Protocol II in order to have S. boulardii count of ~107/g product since such method enabled use of milder plasticizing condition.

Published: March 2024

Abstract
The impact of microplastics on ecosystems and living organisms is an issue of increasing concern. In this study, sediment samples collected from 3 different stations in 4 settlements on the shore of Lake Van in October 2021 were analyzed for the presence of 4 different types of microplastics, namely LDPE, PP, PS, and PET. Methods such as sieve filtration, organic matter removal and density separation were used to isolate microplastics in the collected samples. After isolating microplastics from the samples, visible microplastics were detected and photographed in the relevant samples, bacterial density was measured with microbiological analysis, microplastic particles were measured with a sensitive balance, the color and shape of microplastics were examined with a stereomicroscope, and microplastic particles were identified with FTIR spectroscopy. The spectra obtained from the sediment samples were compared with reference peaks in KnowItAll and the Spectroscopy Online virtual library and PS was identified as the predominant polymer type. When microplastic was analysed, it was determined that the predominant microplastic form was white/transparent and the microplastic size was between 3 and 5 mm. As a result of microbiological analyses, the presence of Escherichia coli (6/2 100 cfu/ml) was detected in the water samples of Van1 and Erciş1 lakes, and the highest total coliform bacteria count was found in Erciş2 lake. In this study, information about the presence of microplastics in sediment, which is one of the elements of Lake Van aquatic ecosystem, was obtained.
Physical Activity and Its Relationship With Diabetes, Hypertension, and Social Demographic Factors in Rural and Urban Malawi
Authors: Mzumara Thokozani , Banda Owen 
Published: March 2024

Abstract
Background
Physical activity (PA) is an essential component of a healthy lifestyle and is a significant contributor to global health by lowering the risk of morbidity and mortality from cardiovascular disease, cancer, diabetes, and other Non-Communicable Diseases. Despite this, PA research has rarely been the focus of public health activities in Malawi.
Objective
The study aimed to evaluate and compare PA Patterns of urban and rural Malawians and their relationship with hypertension, diabetes, and demographic and behavioral factors.
Methods
This was a cross-sectional study that utilized the secondary research approach. The review analyzed data collected from Karonga and Lilongwe using questionnaires administered from May 2013 to April 2017. The data was entered in the SPSS version 27. Next, the Chi-square test was used for univariate analysis. Furthermore, a binary logistic regression model was used to assess the risk factors. The value of p < 0.05 was considered statistically significant.
Results
The study involved 30575 participants, with 16672 from urban areas and 13903 from rural sites, and 1168 (38.2%) males and 18907 (61.8%) females. Many study participants (97.7%) met WHO criteria for physical activity, with 13610 (97.9%) in rural areas and 16254 (97.5%) in urban areas meeting WHO recommendations. Age, gender, occupation, diabetes diagnosis, and hypertension diagnosis showed a significant association with PA in both settings. However, drinking depicted a strong positive association in urban areas and not in rural areas. Smoking showed no statistically significant associations with PA in both sites (> 0.05).
Conclusion
The study confirms previous work. PA is higher in rural areas than urban areas highlighting the role of urbanization and globalization in African cities. In general, the Malawian population follows the physical activity recommendations closely. However, efforts to improve PA should ensure equity and equal access to PA facilities focusing on men and urban residents, unemployed, hypertension and diabetes patients.

Published: March 2024

Spindle cell carcinoma of the breast is a rare breast malignancy, and it accounts for <1 % of breast neoplasms. Tumours are usually large, well-circumscribed, and cystic-containing lesions in the upper outer quadrant of the breast.
The aim: The main objective of the case report is to highlight our experience with Spindle cell carcinoma of the breast.
Result: A case presentation of a 58-year-old female who was referred from the peripheral hospital to our breast oncology clinic with a left breast mass rapidly growing for the past five months. The mass measured 23cm x 20 cm, palpable in all quadrants of the breast but more in the upper outer quadrant of the breast. Mammography and ultrasound showed a massive heterogeneous left breast solid mass involving the entire breast and all quadrants, with areas of cystic components and increased flow. There were no calcifications noted. She was assessed as BI-RAD 5. A core needle biopsy showed spindle cell carcinoma of the left breast. The patient was offered a modified radical mastectomy.
Conclusion: Spindle cell carcinoma of the breast poses a diagnostic challenge due to the rarity of the disease; overlapping morphological features on histology and biomarkers specific to spindle cells have not been extensively studied
Codzienność rozszczelniona. O "Codziennej walce" Manu Larceneta
Authors: Kaja Damian 
Published: March 2024

In the proposed reading of Manu Larcenet’s Le Combat Ordinaire, everyday life appears not only as the setting of the story but also its fundamental—though by no means obvious, despite the abundance of everyday life imagery and motifs—theme. In Larcenet’s unspectacular narration, conducted in a tone oscillating between buffo and serious, human day-to-day affairs, obscured by the facade of ritual, appear as an effort, a task to complete, a risk to be taken, a problem of existence in the “cracks” of which the most important experiences occur, defined by the dialectics of life and death, health and illness, nature and culture, order and disorder.
The article presents an analysis of the key dimensions of this “everyday struggle:” from the textual game whose stake is the axiology of everyday life (the issue of intimate diary, the value of journalism as a profession), to the sense of locality and the construction of identity based on memory and postmemory, to use Marianne Hirsch’s concept (references to the war in Algeria). The interpretation of Larcenet’s graphic novel was carried out based on three premises: (1) the everyday settles into fiction thanks to mimesis; (2) contact with everyday life may lead to an epiphanic revelation of a spiritual truth (drawing on Jolanta Brach-Czaina’s concept described in her philosophical essay Szczeliny istnienia [Cracks in Existence], this phenomenon can be called the “unsealing” of everyday life); (3) literary depictions of human daily existence are where literature and sociology intersect, as a result of which literary works (or, comics in this case) help reveal the structures of everyday life.
Director–Composer Duo: Polanski & Komeda’s Deconstruction of Film Music Conventions in Horror Cinema. "Fearless Vampire Killers" (1967) and "Rosemary’s Baby" (1968)
Authors: Pomostowski Piotr 
Published: March 2024

This article looks at the relationship between music and image in the two final films that Roman Polanski made with Krzysztof Komeda. Fearless Vampire Killers and Rosemary’s Baby are cinematic examples of a very close collaboration between a director and a composer. The article deals with the function of music in relation to genre films. The most important question is the extent to which Krzysztof Komeda’s compositions adhere to or depart from the horror film music convention. A key issue in this context, and one that applies to both of the analyzed films, is the technique of leitmotifs which Polanski and Komeda developed already in their first short films. In Fearless Vampire Killers and Rosemary’s Baby, the jointly developed director-composer method evolved greatly, and Polanski’s collaboration with Komeda took on a very distinctive style, which the author of this article attempts to describe and define.

The text is a translation of an excerpt from the chapter "Nieustraszeni zabójcy wampirów i Dziecko Rosemary, czyli filmowe wyzwanie dla jazzmana, który przestaje nim być” [The Fearless Vampire Killers and Rosemary’s Baby, or a film challenge for a soon-to-be ex-jazzman] in the book Reżyser na ścieżce dźwiękowej.
