A machine learning approach for computation of cardiovascular intrinsic frequencies
Authors: Alavi Rashid , Wang Qian , Gorji Hossein , Pahlevan Niema M.
Published: October 2023

Analysis of cardiovascular waveforms provides valuable clinical information about the state of health and disease. The intrinsic frequency (IF) method is a recently introduced framework that uses a single arterial pressure waveform to extract physiologically relevant information about the cardiovascular system. The clinical usefulness and physiological accuracy of the IF method have been well-established via several preclinical and clinical studies. However, the computational complexity of the current L2 optimization solver for IF calculations remains a bottleneck for practical deployment of the IF method in real-time settings. In this paper, we propose a machine learning (ML)-based methodology for determination of IF parameters from a single carotid waveform. We use a sequentially-reduced Feedforward Neural Network (FNN) model for mapping carotid waveforms to the output parameters of the IF method, thereby avoiding the non-convex L2 minimization problem arising from the conventional IF approach. Our methodology also includes procedures for data pre-processing, model training, and model evaluation. In our model development, we used both clinical and synthetic waveforms. Our clinical database is composed of carotid waveforms from two different sources: the Huntington Medical Research Institutes (HMRI) iPhone Heart Study and the Framingham Heart Study (FHS). In the HMRI and FHS clinical studies, various device platforms such as piezoelectric tonometry, optical tonometry (Vivio), and an iPhone camera were used to measure arterial waveforms. Our blind clinical test shows very strong correlations between IF parameters computed from the FNN-based method and those computed from the standard L2 optimization-based method (i.e., R≥0.93 and P-value ≤0.005 for each IF parameter). Our results also demonstrate that the performance of the FNN-based IF model introduced in this work is independent of measurement apparatus and of device sampling rate.
Fractional order ATR-FTIR differential spectroscopy for detection of weak bands and assessing the radiation modifications in gamma sterilized UHMWPE
Authors: Saeed Muhammad Mudassir , Mehmood Malik Sajjad , Muddassar Muhammad
Published: October 2023

This study presents a new method for identifying radiation modifications in UHMWPE polymer samples. The method involves using a mathematical technique called fractional order differential transformation on IR spectra obtained through ATR-FTIR spectroscopy. This new method was compared to existing techniques such as FTIR, XRD, and DSC, and it was found to be more sensitive and accurate in detecting radiation-induced changes in the polymer. The study focused on identifying changes in weak IR bands in the UHMWPE samples caused by gamma sterilization while simulating IR spectra using different orders of fractional derivatives and compared them to experimental spectra. It was found that applying a lower order of differentiation was more suitable for identifying radiation-induced changes in the UHMWPE samples. Using this method, they were able to identify specific changes in the gamma irradiated structure, such as the splitting of a single absorption peak into a doublet, which was only present in the 50 kGy irradiated sample. The study also used correlation index analysis, principal component analysis, and hierarchy cluster analysis to analyze the simulated and experimental spectra. These techniques allowed to confirm the effectiveness of the fractional order differential transformation method and to identify the specific regions of the IR spectra that were affected by radiation-induced changes in the UHMWPE samples. Overall, this study presents a new method for identifying radiation-induced changes in UHMWPE polymer samples that is more sensitive and accurate than existing techniques. By identifying these changes, researchers can better understand the effects of gamma sterilization on medical equipment and potentially develop new methods for sterilization that do not damage the equipment.
Simple within-stride changes in treadmill speed can drive selective changes in human gait symmetry
Authors: Browne Michael G. , Stenum Jan , Padmanabhan Purnima , Roemmich Ryan T.
Published: October 2023

Millions of people walk with asymmetric gait patterns, highlighting a need for customizable rehabilitation approaches that can flexibly target different aspects of gait asymmetry. Here, we studied how simple within-stride changes in treadmill speed could drive selective changes in gait symmetry. In Experiment 1, healthy adults (n = 10) walked on an instrumented treadmill with and without a closed-loop controller engaged. This controller changed the treadmill speed to 1.50 or 0.75 m/s depending on whether the right or left leg generated propulsive ground reaction forces, respectively. Participants walked asymmetrically when the controller was engaged: the leg that accelerated during propulsion (right) showed smaller leading limb angles, larger trailing limb angles, and smaller propulsive forces than the leg that decelerated (left). In Experiment 2, healthy adults (n = 10) walked on the treadmill with and without an open-loop controller engaged. This controller changed the treadmill speed to 1.50 or 0.75 m/s at a prescribed time interval while a metronome guided participants to step at different time points relative to the speed change. Different patterns of gait asymmetry emerged depending on the timing of the speed change: step times, leading limb angles, and peak propulsion were asymmetric when the speed changed early in stance while step lengths, step times, and propulsion impulses were asymmetric when the speed changed later in stance. In sum, we show that simple manipulations of treadmill speed can drive selective changes in gait symmetry. Future work will explore the potential for this technique to restore gait symmetry in clinical populations.
Fifty years of evidence on perinatal experience among refugee and asylum-seeking women in Organization for Economic Co-operation and Development (OECD) countries: A scoping review
Authors: Ramadan Marwa , Rukh-E-Qamar Hani , Yang Seungmi , Vang Zoua M.
Published: October 2023

Background

Members of the Organization for Economic Co-operation and Development (OECD) play a significant role in hosting and supporting refugees. Refugees and asylum seekers in OECD countries may face unique challenges in accessing perinatal healthcare. These challenges can impact their use of and experience with perinatal health services leading to poor maternal and infant outcomes. This scoping review describes the general trends in perinatal health research among refugees/asylum seekers in OECD countries over the past fifty years (1970 to 2021) as well as summarizes their perinatal experience.

Methods

Databases including Embase and Medline were searched using relevant key words for "refugee/ asylum seeker", "perinatal ", and " OECD countries.". Articles were excluded if they only involved economic migrants or internally displaced persons, conducted in non-OECD countries, only assessed health behaviors and practices during pregnancy (e.g., smoking), or were published in a language other than English. The final list of articles included 82 unique studies.

Results

In the 40 years between 1970 and 2009, very few studies (n = 9) examined perinatal health among refugees/ asylum seekers in OECD countries. However, an increasing trend was observed over the past decade. Early studies (1980 to 2009) focused more on traditional perinatal outcomes; however, from 2010 onwards, studies related to perinatal experience were more likely to emerge in the global health literature. Access to timely prenatal care remains a challenge with failure to address the root causes of the problem in several OECD countries including those with a long history of hosting refugees. The limited availability of interpretation services and the lack of a patient-centered approach to care have also interfered with the perceived quality of care. In addition, perceived isolation and the limited social support experienced by this vulnerable population have negatively impacted their perinatal experiences in several OECD countries.

Conclusion

Refugee/asylum seekers in OECD countries face a number of challenges during the perinatal period. Policy changes and further research are needed to address access barriers and identify specific interventions that can improve their well-being during this critical period.
Association between gestational weight gain and adverse neonatal outcomes in women conceiving with assisted reproductive technology: Evidence from the NVSS 2019–2021
Authors: Jiang Feifei , Li Yanan , Sun Lipeng
Published: October 2023

Objective

To evaluate the association between gestational weight gain (GWG) and adverse neonatal outcomes in women who conceived using assisted reproductive technology (ART).

Methods

The National Vital Statistics System (NVSS) 2019–2021 provided data for this retrospective cohort study. Adverse neonatal outcomes included premature birth, small for gestational age (SGA), large for gestational age (LGA), macrosomia, low birth weight (LBW), and other abnormal conditions. Any adverse outcome was defined as at least one of the above six outcomes. Multivariate logistic regression analysis was employed to evaluate the associations between GWG and different outcomes, after adjusting for confounding factors. These associations were further assessed in subgroups of maternal age at delivery, paternal age at delivery, preconception body mass index (BMI), gestational age, maternal race, parity, gestational diabetes, and gestational hypertension.

Results

Totally 108201 women were included, with 22282 in the insufficient GWG group, 38034 in the sufficient GWG group, and 47885 in the excessive GWG group. Women with insufficient GWG [odds ratios (OR) = 1.11, 95%CI: 1.07–1.16, P<0.001] and excessive GWG (OR = 1.14, 95%CI: 1.10–1.18, P<0.001) had significantly greater risks of any adverse outcome than those with sufficient GWG. In contrast to sufficient GWG, insufficient GWG was associated with significantly elevated risks of premature birth (OR = 1.42, 95%CI: 1.35–1.48, P<0.001), SGA (OR = 1.45, 95%CI: 1.37–1.53, P<0.001), LBW (OR = 1.47, 95%CI: 1.37–1.58, P<0.001), and other abnormal conditions (OR = 1.32, 95%CI: 1.27–1.39, P<0.001), and excessive GWG was associated with significantly lower risks of premature birth (OR = 0.86, 95%CI: 0.83–0.90, P<0.001), SGA (OR = 0.79, 95%CI: 0.75–0.83, P<0.001), LBW (OR = 0.85, 95%CI: 0.79–0.91, P<0.001), and other abnormal conditions (OR = 0.92, 95%CI: 0.88–0.96, P<0.001). Infants born to women with insufficient GWG had significantly decreased risks of LGA (OR = 0.71, 95%CI: 0.66–0.75, P<0.001) and macrosomia (OR = 0.68, 95%CI: 0.63–0.74, P<0.001), and infants born to women with excessive GWG had significantly increased risks of LGA (OR = 1.50, 95%CI: 1.44–1.56, P<0.001) and macrosomia (OR = 1.60, 95%CI: 1.51–1.69, P<0.001).

Conclusion

Insufficient GWG and excessive GWG were associated with increased risks of any adverse outcome than sufficient GWG in women who conceived with ART, indicating the applicability of recommended GWG by the Institute of Medicine (IOM) in this population.
Association of inflammation-related markers and diabetic retinopathy severity in the aqueous humor, but not serum of type 2 diabetic patients
Authors: Saucedo Lucia , Pfister Isabel B. , Schild Christin , Garweg Justus G.
Published: October 2023

Diabetic retinopathy (DR) is a frequent microvascular complication of diabetes mellitus, and inflammatory pathways have been linked to its pathogenesis. In this retrospective, observational pilot study, we aimed to compare the concentrations of four inflammation-related proteins, ZAG, Reg-3a, elafin and RBP-4, in the serum and aqueous humor of healthy controls and diabetic patients with different stages of DR. The concentrations of VEGF-A, IL-8, IL-6 were determined in parallel as internal controls. In the serum, we did not find significant differences in the concentrations of target proteins. In the aqueous humor, higher levels of ZAG, RBP-4, Reg-3a and elafin were observed in advanced nonproliferative DR (NPDR)/ proliferative DR (PDR) compared to controls. The levels of ZAG and RBP-4 were also higher in advanced NPDR/PDR than in nonapparent DR. Normalization of target protein concentrations to the aqueous humor total protein demonstrates that a spill-over from serum due to breakage of the blood-retina barrier only partially accounts for increased inflammation related markers in later stages. In conclusion, we found elevated levels of Reg-3a, RBP-4, elafin and ZAG in advanced stages of diabetic retinopathy. Higher levels of pro-inflammatory proteins, Reg-3a and RBP-4, might contribute to the pathogenesis of diabetic retinopathy, as the parallel increased concentrations of anti-inflammatory molecules elafin and ZAG might indicate a compensatory mechanism.
Age-dependent differences in using FinTech products and services—Young customers versus other adults
Authors: Krupa Dorota , Buszko Michał
Published: October 2023

The purpose of this paper was to identify and evaluate differences in the attitudes to using FinTech products and services in Poland adopted by two study cohorts–one comprised of young customers, born no earlier than in 1990, and the other comprised of other adults. The main motivation for our research was to answer the question if young people growing up in the market economy will behave differently in the use of FinTech than older generations living in the former political and economic system. We also wanted to find the factors that determine the perception and willingness to use FinTech in the mentioned age groups. The data discussed in the paper were provided by the CAWI survey that was conducted in 2020 and covered a sample of 1,153 adult Poles. To achieve our goal, we used nonparametric statistical testing and the backward stepwise logistic regression models. The research demonstrated that young customers showed considerably more interest in all the aspects of the use of FinTech within the framework of our study than the other adults. Regarding the experience of using FinTech, such determinants as the male gender, the larger household in which a given respondent lives, and the possibility of making financial decisions independently exerted more impact on the young customers cohort than on the other adults. Irrespective of their opinion about FinTech, the persons under 30 years of age are more likely to use FinTech beyond average than the other adults whereas the persons over 30 years of age will do so only if they evaluate FinTech very well.
The data quality and applicability of a Danish prehospital electronic health record: A mixed-methods study
Authors: Kjær Jeannett , Milling Louise , Wittrock Daniel , Nielsen Lars Bak , Mikkelsen Søren
Published: October 2023

Background

Without accurate documentation, it can be difficult to assess the quality of care and the impact of quality improvement initiatives. Prehospital lack of documentation of the basic measurements is associated with a twofold risk of mortality. The aim of this study was to investigate data quality in the electronic prehospital patient record (ePPR) system in the Region of Southern Denmark. In addition, we investigated ambulance professionals’ attitudes toward the use of ePPR and identified barriers and facilitators to its use.

Method

We used an explanatory sequential mixed-methods design. Phase one consisted of a retrospective assessment of the data quality of ePPR information, and phase two included semi-structured interviews with ambulance professionals combined with observations. We included patients who were acutely transported to an emergency department by ambulance in the Region of Southern Denmark from 2016 to 2020. Data completeness was calculated for each vital sign using a two-way table of frequency. Vital signs were summarised to calculate data correctness. Interviews and observations were analysed using thematic analysis.

Results

Overall, an improvement in data completeness and correctness was observed from 2016–2020. When stratified by age group, children (<12 years) accounted for the majority of missing vital sign registrations. In the thematic analysis, we identified four themes; ambulance professionals’ attitudes, emergency setting, training and guidelines, and tablet and software.

Conclusion

We found high data quality, but there is room for improvement. The ambulance professionals’ attitudes toward the ePPR, working in an emergency setting, a notion of insufficient training in completing the ePPR, and challenges related to the tablet and software could be barriers to data completeness and correctness. It would be beneficial to include the end-user when developing an ePPR system and to consider that the tablet should be used in emergency situations.
Towards mutual recognition: Ricoeur against Kojève
Authors: Shashlova Ekaterina
Published: October 2023

In this article, we examine two philosophical theories of recognition: those of Paul Ricoeur and Alexandre Kojève. We trace this line of development in the theory of recognition as a return from Ricoeur to Kojève. Our hypothesis is that over the past twenty years, the theory of recognition has undergone a change in content and has transformed into a theory of misrecognition. In turn, the theory of misrecognition is grounded in the struggle between subjects and brings us back to the discourse of the struggle between the Slave and the Master. This transformation from struggle to reciprocity and vice versa, we argue, suggests that a theory of identity formation as a process of resistance to assujettissement is in demand at this moment in history. In the 2010s, as the theory of misrecognition took shape primarily in the English‑speaking world, the constitution of the subject began to be understood once again as the outcome of struggles within feminist, Marxist, and other emancipatory theories. We examine both Ricoeur’s arguments against Kojève, Althusser, and the theory of misrecognition in general, as well as the «return» of Kojève’s arguments in the contemporary theory of misrecognition.

A excepção Derrida – O “eleito secreto” dos animais A veia onto-antropo-teo-lógica em questão
Authors: Bernardo Fernanda
Published: October 2023

«A excepção Derrida – o “eleito secreto” dos animais» pretende sobretudo evidenciar três questões fundamentais de todo interligadas: 1.) Sem a reificar numa filosofia teórico-sistemática, destacar a Desconstrução de Derrida como um “idioma filosófico” – o da différance ou da alteridade absoluta – dotada de pressupostos “teóricos” específicos (khôra, messiânico); 2.) Destacar e esclarecer o significado da “excepção derridiana” no tocante à questão do animal e da animalidade no contexto da sacrificialista ocidentalidade filosófico-cultural; 3.) Destacar a relevância da questão do animal para repensar, em novos termos, a questão do próprio humano/sujeito – ainda essencialmente estruturado à luz de uma subjetividade metafísica –, sublinhando a inestimável contribuição da Desconstrução para repensar a eventual excepcionalidade do humano entre os viventes e para levar a bom termo a guerra pela compaixão, contribuindo assim para o surgimento de novas Luzes para a promessa do “por-vir” [«à-venir»] de uma outra humanidade e, consequentemente, de uma outra civilização.
Analysis of the capital structure of startups in light of the tradeoff and pecking Order theories
Authors: Colombo Gabriela de Carvalho , Gomes Matheus da Costa , Eça João Paulo Augusto , Valle Maurício Ribeiro do
Published: October 2023

Purpose: Startups have significant differences compared to other companies. They have many intangible assets (e.g., team tenure and experience of founders), are risky, and tend not to generate profits in their initial years (Heirman & Clarysse, 2007; Weber & Zulehner, 2009). Does the startups’ financing choice also differ from that of traditional companies? We analyzed the capital structure of startups in their first years of life based on the classic tradeoff and pecking order theories. Methodology/approach: We collected data on 40 startups in the city of Ribeirão Preto, São Paulo, Brazil, through a questionnaire on the profiles of the founders, company characteristics, bottom-line performance and financing sources. The data collected covered the year of founding and the three subsequent years. Findings: The results indicated that these startups mainly financed themselves through the founders’ capital in all four years covered. Only in the third year did they start using resources generated internally, indicating pecking order adherence. However, the presence of angel investors and government subsidies contrasted with the absence of bank debt. In line with the tradeoff theory, bank debt was not a viable financing option in the early years of these firms since they had low profitability and high risk. Theoretical/methodological contributions: We offer a theoretical contribution by analyzing the adequacy of traditional financial theories in the specific context of startups. Originality: The finance literature about startups is scarce, and few studies have analyzed these companies from the capital structure theoretical perspective. Social contributions / for management: We provide a panorama of the financing of startups to support their financial planning regarding fundraising.
A critique of andragogy in the South African TVET context
Authors: Moll Ian
Published: October 2023

Andragogy, the ‘art and science of helping adults learn’ (Knowles, 1980:43), had some purchase in the South African technical and vocational education and training (TVET) sector, where writers and lecturers have been attracted to the idea that adult education has its own theoretical and epistemological principles. Recently, a notable number of writings in African countries, including South Africa, have advocated the adoption of andragogic methods to overcome the inadequate provision of workplace (procedural) learning in relation to formal (propositional) learning in TVET institutions. However, this article argues that andragogy is culturally biased because it is based on white, male, middle-class norms of the 1960s. Its assumptions about adult learning tend to marginalise others on the basis of race, gender, and cultural difference. This tendency is given a peculiar form in South Africa owing to the historical relationship between andragogy and fundamental pedagogics in the academic theorisation of apartheid ideology. On the strength of these historical, political, and cultural levels of criticism, it is suggested that andragogy has little veracity or credibility for TVET.
“No soy ilegal, soy profesional”: autoidentificación de docentes colombianos en Estados Unidos
Authors: Garzón Duarte Eliana , Posada Ortiz Julia Zoraida
Published: October 2023

Este artículo resulta de una investigación de enfoque cualitativo desarrollada con veinte docentes de idiomas, nacidos y formados académicamente en Colombia, que se encuentran vinculados laboralmente en colegios públicos de Estados Unidos. El objetivo principal fue explorar e interpretar la autoidentificación de estos docentes y la percepción de ellos en un país que estaba recientemente permeado por el discurso polémico sobre la migración, del entonces presidente Donald Trump (2017-2021). El grupo de participantes respondió a un cuestionario en línea y a una entrevista en Skype. El análisis de datos se llevó a cabo mediante un proceso de codificación y agrupación de patrones comunes en las respuestas. Los resultados evidencian que el pensamiento colonial persiste en la sociedad y deja ver las fronteras simbólicas que marcan desigualdad. De igual manera, los posicionamientos sociales permiten que las identidades individuales y el sentido de pertenencia se negocien y que las autopercepciones de ser se construyan.
Crónicas escolares: un acercamiento a la escritura en primaria
Authors: Melo Linares John Jairo
Published: October 2023

Este artículo presenta los resultados de la investigación “La crónica como oportunidad para favorecer la escritura en ciclo uno”, a partir de la comprensión, elaboración y funcionalidad de este género en diferentes contextos. Para ello, se diseñó una serie de talleres que se trabajaron de manera sincrónica y asincrónica, dada la situación de la educación remota por la pandemia del COVID-19. En este sentido, la investigación se ubicó en el paradigma interpretativo, con enfoque cualitativo y diseño en investigación acción. Como resultado, se evidencia que los estudiantes desarrollaron la capacidad de construir este tipo de textos, mejorar su propia producción textual y fortalecer su expresión escrita. Además, es importante reconocer que la escuela presenta retos, por un lado, para el profesorado en la medida en que se requiere la actualización de sus prácticas pedagógicas y, por el otro, para los estudiantes en el desafío de adquirir y desarrollar competencias comunicativas que les permitan incursionar en el mundo de las producciones propias. En conclusión, la escritura de crónicas tiene un potencial que va más allá del texto, las letras o las reglas ortográficas (enfoque lingüístico), el cual se expande hacia las posibilidades que su autor le quiera dar (psicolingüístico y sociocultural).

Published: October 2023

Primarily known as the author of the Dialogus miraculorum—a collection of exemplary stories that won Caesarius his reputation as the master of Cistercian storytelling—Caesarius of Heisterbach’s strong predilection, however, seems to have been for writing sermons and homilies.
Although they are not as well known today, his Homilies on Jesus’ Childhood are exceptional in many ways. Readers will immediately notice Caesarius’s versatility, as he employs an impressive array of persuasive techniques (quoting scholarly works, interpreting Hebrew names and letters, delving into etymology and numerology), as well as including numerous exempla to instruct both the learned and the simple.
A Weierstrass extremal field theory for the fractional Laplacian
Authors: Cabré Xavier , Erneta Iñigo U. , Felipe-Navarro Juan-Carlos
Published: October 2023

In this paper, we extend, for the first time, part of the Weierstrass extremal field theory in the Calculus of Variations to a nonlocal framework.
Our model case is the energy functional for the fractional Laplacian (the Gagliardo–Sobolev seminorm), for which such a theory was still unknown.
We build a null-Lagrangian and a calibration for nonlinear equations involving the fractional Laplacian in the presence of a field of extremals. Thus, our construction assumes the existence of a family of solutions to the Euler–Lagrange equation whose graphs produce a foliation. Then the minimality of each leaf in the foliation follows from the existence of the calibration.
As an application, we show that monotone solutions to fractional semilinear equations are minimizers.
In a forthcoming work, we generalize the theory to a wide class of nonlocal elliptic functionals and give an application to the viscosity theory.

. We also obtain analogous results in the setting of uniformly parabolic and elliptic equations with bounded, measurable, real and symmetric coefficients. These are the first regularity results for vertical maximal functions without convolution structure.

Published: October 2023

Using microbial endophytes to produce bioactive compounds is a reliable scientific method. This investigation aimed to use the Acacia plant for isolating an endophytic fungal strain that has a bio-ability to produce a bio-crude extract. This study also encompassed the assessment of the extract’s biological efficacy as an antibacterial and anticancer agent. Samples of the Acacia plant were collected from “Shuaib Huraymila,” in Riyadh, Saudi Arabia. The isolation and identification of fungal endophytes was done, and then, the production of crude extract was performed using the isolated endophytes. The profile gas chromatography-mass spectroscopy of the extract was determined, followed by the assessment of its biological activity against drug-resistant infections and cancer cells through in vitro examination. The findings showed that the fungal endophyte was Alternaria (Alternaria sorghi), according to internal transcribed spacer sequencing and basic local alignment search tool analysis. The minimum inhibitory concentrations of the extract were 9.1 and 4.5 mg/mL for methicillin-resistant Staphylococcus aureus and drug-resistant Candida auris, respectively, and the IC50% values were 46.6 and 23.7 mg/mL for MCF-7 and A549, respectively. The findings showed that this strain had no antagonistic action against Culex pipiens. This study concluded that the fungal endophyte isolated from the Acacia plant has the bio-ability to produce antimicrobial and anticancer agents.

Increased circulating microRNA-21 level as a potential indicator for predicting a higher risk of incident fragility fractures
Authors: Si Zhen-Xing , Zhou Shi-Feng , Shen Zi-Long , Yan Jing-Long
Published: October 2023

Context

As a common disease in the elderly, osteoporosis clearly increases the risk of fractures, leading to higher mortality, but the current markers to estimate the risk of fractures are limited. MicroRNA-21 (miR-21) may play an important role in osteoporosis, but the link of this biomarker with fractures was undetermined.

Objectives

We aimed to investigate the association between miR-21 levels and the presence of fragility fractures.

Methods

A total of 200 patients were recruited and miR-21 was collected from baseline serum. The correlation between miR-21 and the fracture risk assessment tool (FRAX) score was analyzed. The incidence of fragility fractures was presented by Kaplan-Meier analysis, and Cox regression analysis was utilized to evaluate risk factors. The diagnostic value of miR-21 was conducted by the area under curve (AUC).

Results

The FRAX score was significantly associated with miR-21 level (p<0.001). According to the 50th percentile of miR-21 content in the overall distribution, the cumulative incidence of fragility fractures was significantly higher in patients with higher miR-21 levels than those with lower levels (75.4, 95 % CI: 69.0–81.8 vs. 59.2, 95 % CI: 42.1–76.3, p<0.001). The results of the Cox regression analysis showed that the miR-21 level was an independent risk factor linked to the incidence of fracture (p=0.005). The optimal cut-off value of the miR-21 was 6.08, and the AUC for predicting fracture was 0.718 (95 % CI, 0.645–0.790).

Conclusions

This study showed that miR-21 has optimal diagnostic performance in the discrimination of fragility fracture, and the circulating miR-21 level in predicting the risk of fragility fracture may have a certain value.

On the computational modeling of English relative clauses
Authors: Fong Sandiway , Ginsburg Jason
Published: October 2023

Even in this era of parameter-heavy statistical modeling requiring large training datasets, we believe explicit symbolic models of grammar have much to offer, especially when it comes to modeling complex syntactic phenomena using a minimal number of parameters. It is the goal of explanatory symbolic models to make explicit a minimal set of features that license phrase structure, and thus, they should be of interest to engineers seeking parameter-efficient language models. Relative clauses have been much studied and have a long history in linguistics. We contribute a feature-driven account of the formation of a variety of basic English relative clauses in the Minimalist Program framework that is precisely defined, descriptively adequate, and computationally feasible in the sense that we have not observed an exponential scaling with the number of heads in the Lexical Array. Following previous work, we assume an analysis involving a uT feature and uRel feature, possibly simultaneously valued. In this article, we show a detailed mechanical implementation of this analysis and describe the structures computed forthat,which, andwho/whomrelatives for standard English.
Living on the edge(s). Settlement revival in the Sacharewo microregion (Białowieża Forest, E Poland) during the Iron Age and Roman Period (1st c. BC/1st c. AD – 5th/6th c. AD)

The article presents the results of research carried out at Sacharewo in the Białowieża Forest, involving excavations of a barrow cemetery associated with the Roman Period and the nearby settlement, which delivered finds from the Early Bronze Age, the Iron Age, the Roman Period and the Modern Period. Noteworthy was a significant amount of material from the Iron Age and the Roman Period, linked with the Hatched Pottery and Wielbark cultures, possibly indicating a certain revival of settlement in that area between the turn of the eras and the 5th/6th century AD. Thanks to the analysis of airborne laser scanning data, it was also possible to identify a complex of ancient arable fields in the surroundings of the barrow cemetery. The excavations were conducted along with sampling for geoarchaeological and archaeobotanical analyses. A significant pool of 14C dates was also collected.

The studies idientified the remains of a stable and continuous (though not very developed and intensive) settlement on the left side of the Leśna River, a barrow cemetery and a field system, possibly used at the same time. This microregion functioned in the first centuries AD, although materials linked to the early Middle Ages were also found. At this stage, however, it is not possible to determine their continuity with finds from the Roman Period. The discoveries also provide an insight into the external cultural influences on the area during the Roman Period.

The conducted research complements other recent findings from the Białowieża Forest, which, given its primeval nature and the limited role of human activity during past centuries, is an excellent area for further investigations of settlement and economy patterns from different periods.

Ruiz-Alias, SA, Pérez-Castilla, A, Soto-Hermoso, VM, and García-Pinillos, F. Influence of the world athletics stack height regulation on track running performance. J Strength Cond Res 37(11): 2260–2266, 2023—A new footwear regulation based on limiting the stack height (i.e., amount of material between the feet and the ground) has been established by World Athletics to ensure that performance is achieved through the primacy of human effort over technology in running shoes. Analyzing the effect of legal and illegal shoes on running performance is therefore needed to determine its effectiveness. Thus, this study aimed (a) to compare the effect of 2 footwear models categorized as legal and illegal by the World Athletics regulation on track running performance and (b) to analyze the derived metrics of the athletes' biomechanics when using each footwear model at racing paces. Within 1 week, 14 highly trained athletes performed 2 testing sessions composed of 2 time trials of 9- and 3-minute duration with 30 minutes of recovery between them. The athletes wore the “Nike ZoomX Dragonfly” track spikes model and the “Nike ZoomX Vaporfly Next % 2” marathon shoe model in a counterbalanced randomized order. The results revealed that (a) there was only a small worthwhile improvement in the 3-minute time trial when using the marathon shoes of 0.97% (−0.04 to 1.98%) and (b) there was a main effect of footwear in 7 of the 9 biomechanical variables analyzed (p ≤ 0.050). The ground contact time was the unique performance predictor (p = 0.005, adjusted R
2 = 0.476). Altogether, the use of legal and illegal running shoes altered the runners form, which only influenced the mid-distance performance.

Harrison, PW, Kelly, VG, Jenkins, DG, McGuigan, MR, Holmberg, PM, and James, LP. Does moderate-load priming activity influence maximal upper-body performance and perceptual state?. J Strength Cond Res 37(11): e581–e587, 2023—The results of previous research indicate that resistance exercise “priming” may improve strength-power measures within 48 hours after their completion. Although researchers have primarily examined performance responses after lower-body priming stimuli, investigations examining the effects of upper-body resistance priming exercises are presently limited. Therefore, the aim of this study was to examine upper-body pushing and pulling performance in addition to perceptual responses 3 and 27 hours after moderate-load (ML) upper-body resistance priming exercise. Fourteen resistance-trained men were assigned to complete ML priming (4 × 3 bench press and bench pull at 65% 1RM [repetition maximum]) and control (rest) protocols in a randomized and counterbalanced order. Peak velocity during the bench throw and bench pull tests involving different loads (25, 50, and 75% 1RM) showed no practical change at 3 and 27 hours after the priming session (p = 0.216–0.99, Cliff's d = −0.041 to 0.225). Small effect size increases in perceptual measures (“physical feeling,” “physical performance,” “aggression” [p = 0.400–0.553, Cliff's d = 0.183–0.201], and “muscular heaviness” [p = 0.178, Cliff's d = 0.231]) were found at 3 hours postpriming. A moderate practical increase was observed in perceived “physical feeling” compared with control (p = 0.385, Cliff's d = 0.349) in addition to small effect size increases in perceived “physical performance” and “aggression” (Cliff's d = 0.243–0.290) at 27 hours after priming activities. These results indicate that upper-body strength-power changes within 27 hours after ML upper-body resistance exercise priming are not practically meaningful.
