Published: October 2022

Background
Lactate dehydrogenase (LDH) is associated with the prognosis of many diseases, but the relationship between LDH and the poor prognosis (recurrence and death) of acute ischemic stroke (AIS) has not been fully clarified. This study aimed to investigate the association between admission LDH level and poor prognosis in patients with AIS.

Methods
This retrospective study enrolled AIS patients treated in Taizhou Hospital of Zhejiang Province from July 2019 to December 2019. Poor prognosis included AIS recurrence and all-cause death at 3, 6, and 18 months. The correction between LDH and poor prognosis or all-cause death was assessed. Lasso Cox expression and multivariate Cox expression analyses were used to evaluate the association of LDH with the risk of poor prognosis and all-cause death, respectively. A nomogram was constructed to evaluate the predictive Values of LDH for the poor prognosis and all-cause death of AIS.

Results
732 patients were included in the study. Multivariate analysis shows that admission LDH levels were significantly correlated with poor prognosis [odds ratio (OR),1.003; 95% confidence interval (95% CI), 1.001–1.005; P = 0.001] and all-cause death (OR, 1.005; 95% CI, 1.000–1.009; P = 0.031). The correlation analysis showed that admission LDH level was positively correlated with National Institutes of Health Stroke Scale (NIHSS) score and modified Rankin Scale (mRS) score. Time-dependent receiver operating characteristic (td-ROC) curves analysis showed that the AUC values of admission LDH level for predicting prognosis of AIS patients in 3-month, 6-month, 12-month and 18-month were 0.706 (95% CI, 0.604–0.810), 0.653 (95% CI, 0.583–0.723), 0.616 (95% CI, 0.556–60676) and 0.610 (95% CI, 0.552–0.680), respectively. And td-ROC also showed that the AUC values of admission LDH level for predicting all-cause death of AIS patients in 3-month, 6-month,12-month and 18-month were 0.861 (95% CI, 0.764–0.958), 0.824 (95% CI, 0.753–0.890), 0.726 (95% CI, 0.633–0.819) and 0.715 (95% CI, 0.622–0.807), respectively. The nomograms were constructed to create the predictive models of the poor prognosis and all-cause death of AIS.

Conclusion
Higher LDH levels are independently associated with poor prognosis and all-cause death of AIS.

Między jasnością a ciemnością. O wybranych leksemach wyrażających intensywność światła w twórczości Janusza Stanisława Pasierba
Authors: Kaptur Ewa , Sławek Jolanta 
Published: October 2022

The poetic texts of priest Pasierb present a peculiar sensitivity to the names of colours. The author of Koziorożec ( Capricorn ) paid particular attention to the role of light, hence his works present a separate category of expressions regarding light and darkness, flash and brightness. It is the result of, among others, the culturallyconditioned evaluation of light and dark and the related axiological attitude towards the world. Also present are numerous lexemes situated in the lexical field of, for instance, red, yellow, golden, blue, black and white. The collected material shows that the names of colours present in Pasierb’s works do not so much name reality as co-create the mood of particular texts, creating as a result a set of delicate poetic impressions.
On the Megarians of Metaphysics IX 3
Authors: Chame Santiago 
Published: October 2022

Abstract
In this paper, I compare the Megarian thesis of Metaphysics IX 3 with other sources on the Megarians in order to clarify two questions: that of the unity and nature of the so-called Megarian school and that of Aristotle’s broader argument in IX 3. I first review the disputed issue of the status of the Megarian school and then examine two hypotheses regarding the identity behind Aristotle’s allusion in IX 3. Third, I explore the connection between Megarianism and Plato’s Euthydemus, a task that helps us to contextualize Aristotle’s anti-Megarian polemic. Lastly, I build on the preceding argument in a re-examination of the Eleatic hypothesis with regard both to the Megarians as a whole and to the thesis that Aristotle transmits.
“Unmanageable”: Exploring Black Girlhood, Storytelling, and Ideas of Beauty
Authors: Rowe Kristin Denise 
Published: October 2022

AbstractThis article explores how Black women use storytelling to construct their Black girlhood on the axes of Black hair and beauty politics. The study includes a discourse analysis of a series of focus groups with a student organization dedicated to Black women’s natural hair at a midwestern predominantly white institution. I ask: How do young Black women use storytelling as a tool to construct, recall, and (re)negotiate their childhood experiences of hair and beauty politics? I explore the ways these women use storytelling to articulate how their Black girlhood was in part shaped by encounters with hair politics and constructions of beauty. These “hair moments” that they recall reveal complex negotiations of standards of beauty. I analyze three themes that emerge from these conversations: (1) shared experiences around play, imagination, and relationship to images of mainstream beauty; (2) family as a social unit that socializes Black girls around beauty; and (3) adolescence, prom, and contested notions of appropriate “formal” adornment. These themes among these young women illustrate shared experiences, negotiation/critique, and meaning making around concepts of beauty. This study contributes to conversations around beauty culture, Black hair politics, and the bourgeoning field of Black girlhood studies. Through understanding how Black women reflect on their girlhood experiences of the politics of hair and beauty, we can better understand the inner experiences of Black girls, and the complexities of how they come to know and understand their bodies.
Patterns of individual variation and change in Golden Age Spanish. An analysis of three linguistic variables in a corpus of private correspondence
Authors: Blas-Arroyo José Luis 
Published: October 2022

AbstractBased on a corpus of private correspondence written by 16 authors from the Golden Age period, this study analyses the idiolectal distributions of three distinctive variants of early classical Spanish. After comparing these distributions at different times in the lives of these individuals against those found in the same period in previous variationist studies, the existence of three idiolectal profiles is detected: refractory, in-between and followers. The first two profiles are in the majority, although some examples of the third are also found. In any event, these profiles are not monolithic. On the contrary, with a few exceptions, speakers do not follow the same patterns in the three cases of variation studied. Moreover, a longitudinal analysis of the letters at different life stages shows that the stability of the distributions is the norm. Nevertheless, there are also some exceptions, i.e. authors who evolve significantly in the distribution of the variants, although almost always in the same direction: the progressive replacement of vernacular forms by others, following the prevailing trends of change. The main theoretical implications of these results are connected to previous findings in the literature on earlier stages of other European languages dealing with the role of idiolectal variation in shaping linguistic variation and change.

AbstractThe ifo Education Survey is a representative opinion survey of the German voting-age population on education topics that has been conducted annually since 2014. It covers public preferences on a wide range of education policy issues ranging from early childhood education, schools, and apprenticeships to university education and life-long learning. The dataset comprises several survey experiments that facilitate investigating the causal effects of information provision, framing, and question design on answering behavior. This paper gives an overview of the survey content and methodology, describes the data, and explains how researchers can access the dataset of over 4000 participants per wave.
Pre-eclampsia and maternal health through the prism of low-income countries
Authors: Medjedovic Edin , Kurjak Asim , Stanojević Milan , Begic Edin 
Published: October 2022

AbstractHypertensive syndrome in pregnancy complicates up to 15% of pregnancies, and preeclampsia (PE) occurs in about 3–10% of pregnant women. Inadequate prenatal care is associated with higher mortality from PE, possibly due to reduced monitoring, detection, and missed opportunities for early intervention. The imperative of the clinician’s work is to monitor the symptoms and clinical signs of PE, and stratification of patients in relation to the risk of PE is essential. PE represents a multisystem inflammatory response, and the consequences can be expected in all organs. The question of the effect of PE on long-term maternal health is raised. The aim of the paper is to present the effect of PE on the patient’s health through the prism of low-income countries.

We demonstrate the effectiveness of our approach for several examples, including the BPCA problem.
Optical-cavity mode squeezing by free electrons
Authors: Di Giulio Valerio , García de Abajo F. Javier 
Published: October 2022

Abstract
The generation of nonclassical light states bears a paramount importance in quantum optics and is largely relying on the interaction between intense laser pulses and nonlinear media. Recently, electron beams, such as those used in ultrafast electron microscopy to retrieve information from a specimen, have been proposed as a tool to manipulate both bright and dark confined optical excitations, inducing semiclassical states of light that range from coherent to thermal mixtures. Here, we show that the ponderomotive contribution to the electron–cavity interaction, which we argue to be significant for low-energy electrons subject to strongly confined near-fields, can actually create a more general set of optical states, including coherent and squeezed states. The postinteraction electron spectrum further reveals signatures of the nontrivial role played by A
2 terms in the light–matter coupling Hamiltonian, particularly when the cavity is previously excited by either chaotic or coherent illumination. Our work introduces a disruptive approach to the creation of nontrivial quantum cavity states for quantum information and optics applications, while it suggests unexplored possibilities for electron beam shaping.
Failure process of steel–polypropylene hybrid fiber-reinforced concrete based on numerical simulations
Authors: Wu Hailin , Zhang Yu , Yao Kaisheng , Yang Bozhen 
Published: October 2022

Abstract
In this work, we studied the failure mechanism of steel–polypropylene hybrid fiber reinforced concrete (HFRC) at the mesolevel. The uniaxial tensile test of HFRC was simulated using ABAQUS finite element analysis software. Then, the relationship between the mesoscale failure process and the mechanical properties was analyzed based on the simulation results. The results showed that the cracks first appeared in the interfacial transition zone and then gradually propagated into the mortar elements and intersected with adjacent cracks, forming major macroscopic cracks. According to the crack evolution process, the incorporation of steel fibers and polypropylene fibers changed the concrete crack expansion paths and served to inhibit crack expansion. Furthermore, the increase in the hybrid fiber volume had a positive effect on the mechanical properties, and the steel fibers dominated in providing reinforcement compared to the polypropylene fibers.
What makes the dative-experiencer construction in Modern Hebrew different from its counterparts in European languages?
Authors: Halevy Rivka 
Published: October 2022

AbstractThe paper proposes a usage-based account of a largely productive pattern of dative experiential sentences in Modern Hebrew that stand in contra-distinction to their parallels in Indo-European languages. In the pattern under consideration, the dative-Experiencer is non-topical, following an invariable predicate in masculine singular form. The paper seeks to prove that the construction in Hebrew is essentially a subjectless construction. Its origin is traced back to Biblical Hebrew, but its proliferation in present-day language is assumed to be contact-facilitated by a parallel subject-like dative-Experiencer construction widespread in Slavic and Yiddish languages.

Published: October 2022

Abstract
Over the years, it has been proven that all machines that run continuously or even for a short period of time experiences breakdowns, reduced efficiency and damage to the parts. Considering one such manufacturing process is welding process where strip welding is studied for condition monitoring and prediction of online quality of the weld. The proposed embodiment discusses a predictive condition monitoring of a welding process, using acoustic sensors and processing their data. Converting the processed data to a predictive model, comparing different Machine Learning (ML) algorithms like Decision Tree (DT), Artificial Neural Networks (ANN) and Convolutional Neural Networks (CNN) based on the validation and training results, selecting the suitable algorithm for online or real-time weld quality prediction is the objective of the proposed embodiment. According to the research, effectively executing the proposed solution can improve its life, efficiency, and utilization. The training accuracy is observed to be 97 % for DT, 50 % for ANN and 67 % for CNN. DT, on the other hand, has a validation accuracy of 94.7 %, ANN has 47.65 % and CNN has 65.8 %. DT produced the best results in the study, initially DT prediction model is used in offline testing of the new data-set for individual weld class and the system produced 97 % accuracy. Furthermore the DT prediction model is implemented in online weld quality prediction in three classes: Bad weld, OK weld and Good weld where the system produced 90 % accuracy in real-time prediction.
Multi-technique Approaches to Evaluate the Pozzolanic Properties of Alkali-Rich Calcined Kaolinite and Bentonite Clay Blends
Authors: Borno Ishrat Baki , Ashraf Warda , Khan Rakibul I. , Tahsin Adhora 
Published: October 2022

Abstract
This study presents an investigation of the reactivity of three clay blends containing kaolinite and bentonite using various experimental techniques. Two of the clay blends were fused with alkali hydroxides via co-calcination to achieve better reactivity. The reactivities of thermally activated clays were evaluated using inductively coupled plasma-optical emission spectrometry (ICP-OES), in situ attenuated total reflectance-Fourier transform infrared spectroscopy (ATR-FTIR), and the rapid, relevant, and reliable (R3) test. The ICP-OES test was used to measure the solubility rate of silicon and aluminum from the clay blends with and without alkali addition. In situ ATR-FTIR was used to monitor the portlandite and calcium silicate hydrate peak changes at the early stage of the reaction. Eventually, both ICP-OES and ATR-FTIR test results were analyzed in comparison to that of the standard R3 test. It was observed that silicon and aluminum solubility measurement using ICP-OES can be an effective method for quick screening of the reactivity of a large number of samples with minimal sample preparation.

Published: October 2022

Abstract
This article, on the basis of experimental research, combines theoretical analysis and numerical calculation. In addition, the research, while taking into consideration different fracture lengths, confining pressure of rock mass mechanics properties, and behavior of evolution law, establishes and reflects the unique characteristics of the processes of fractured rock mass deformation and destruction of the damage constitutive model. In this instance, the discrete element method numerical has been discussed from the perspective of mesoscopic fracture mechanism of the fractured rock mass. The results show that the capacity of resistance of rock mass deformation and destruction along with the increase of fracture length, the peak stress of rock mass, the elastic modulus, and peak strain are positively correlated with the confining pressure. Furthermore, an increase in the confining pressure, transition of rock mass from brittle to ductile, an intact sample to shear failure pattern by stretching evolution, and different fracture lengths are characterized by shear failure form. Based on the statistical damage theory and Drucker Prager yield criterion, the damage constitutive model of fractured rock mass has been determined, and the physical meaning of the model parameters has been clarified through experimental analysis. The strength characteristics and damage evolution law of fractured rock mass revealed by the damage constitutive model are consistent with the test results, thereby verifying the rationality of the model. According to the numerical simulation of the evolution characteristics of the number of microcracks, the failure process of rock mass can be divided into four stages, namely crack initiation stage, crack steady growth stage, pre-peak crack accelerated growth stage, and post-peak crack accelerated growth stage. The simulation results of the deformation failure process and model are basically the same as those of the laboratory experiment. The theoretical results are expected to provide an important theoretical foundation for theoretical research of rock mass mechanics and engineering stability evaluation.
A Contemporary Free Verse from American and Ukrainian Readers’ Perspectives
Authors: Kulchytska Olga , Malyshivska Iryna 
Published: October 2022

The study presents an experiment aimed at discovering similarities and differences in how American and Ukrainian participants perceived contemporary free verse. Three poems were examined from the perspectives of intertextual/infratextual/intratextual context dimensions. The presence of intertextual characteristics – reflecting social reality and metaphoric content – was recognized by the majority in both groups of participants, yet across the groups, there were differences in the degree of value placed on each characteristic. Differences in views on the infratextual contexts reflect the variability of functions performed by the initial/intermediate/closing parts of the poems. As regards intratextual context dimension, there were significant similarities in the participants’ views on the imagery, in the constructed text-worlds, emotional responses, interpretations, and encountered difficulties. The analysis of the intratextual contexts of the poems indicates that some texts may drive readers’ interpretations, thus reducing the role of culture in their reception.
