description: Easy and mostly free access to the internet has resulted in the growing use of open source software (OSS). However, it is a common perception that closed proprietary software is still superior in areas such as software maintenance and management. The research model of this study establishes a relationship between maintenance issues (such as user requests and error handling) and support provided by open source software through project forums, mailing lists and trackers. To conduct this research, we have used a dataset consisting of 120 open source software projects, covering a wide range of categories. The results of the study show that project forums and mailing lists play a significant role in addressing user requests in open source software. However according to the empirical investigation, it has been explored that trackers are used as an effective medium for error reporting as well as user requests.

description: The computation of the optical conductivity of strained and deformed graphene is discussed within the framework of quantum field theory in curved spaces. The analytical solutions of the Dirac equation in an arbitrary static background geometry for one dimensional periodic deformations are computed, together with the corresponding Dirac propagator. Analytical expressions are given for the optical conductivity of strained and deformed graphene associated with both intra and interbrand transitions. The special case of small deformations is discussed and the result compared to the prediction of the tight-binding model.

description: Tissue engineering research is a multidisciplinary effort that incorporates the use of resources from various fields to address specific problems. Biomatrix scaffolds have recently been more widely used to improve the culture of cells by supporting their differentiated functions more than any known matrix extract or purified matrix component. However, they are not readily converted to industrial scale usage. Additionally, improved imaging techniques using ultrasound have been developed and are being used to characterize the biomatrix scaffolds in more detail to assess which preparation might be best for industrially scaled studies. The primary objective of this thesis was to identify methods that would most optimally use the biomatrix scaffold extracts while preserving the critical components of the matrix but in a way that was scalable for use in industry. We also demonstrate the use of novel ultrasound technologies that are non-invasive and non-destructive in the evaluation of biomatrix scaffolds.

description: A growing number of systems are represented as networks whose architecture conveys significant information and determines many of their properties. Examples of network architecture include modular, bipartite, and core-periphery structures. However inferring the network structure is a non trivial task and can depend sometimes on the chosen null model. Here we propose a method for classifying network structures and ranking its nodes in a statistically well-grounded fashion. The method is based on the use of Belief Propagation for learning through Entropy Maximization on both the Stochastic Block Model (SBM) and the degree-corrected Stochastic Block Model (dcSBM). As a specific application we show how the combined use of the two ensembles -SBM and dcSBM- allows to disentangle the bipartite and the core-periphery structure in the case of the e-MID interbank network. Specifically we find that, taking into account the degree, this interbank network is better described by a bipartite structure, while using the SBM the core-periphery structure emerges only when data are aggregated for more than a week.

description: In this paper, we present empirical studies on conversational recommendation tasks using representative large language models in a zero-shot setting with three primary contributions. (1) Data: To gain insights into model behavior in "in-the-wild" conversational recommendation scenarios, we construct a new dataset of recommendation-related conversations by scraping a popular discussion website. This is the largest public real-world conversational recommendation dataset to date. (2) Evaluation: On the new dataset and two existing conversational recommendation datasets, we observe that even without fine-tuning, large language models can outperform existing fine-tuned conversational recommendation models. (3) Analysis: We propose various probing tasks to investigate the mechanisms behind the remarkable performance of large language models in conversational recommendation. We analyze both the large language models' behaviors and the characteristics of the datasets, providing a holistic understanding of the models' effectiveness, limitations and suggesting directions for the design of future conversational recommenders

description: Introduction: Wellness Recovery Action Planning (WRAP) is a structured recovery education programme used internationally for anyone who wishes to create a positive change in their life. It was developed by Mary Ellen Copeland and Jane Winterling in the late 90s, resulting from a search of programmes or initiatives that could support their wellness. Since then, many studies have been conducted into the efficacy of the programme for those with a mental health/addiction challenge. However, to date there has been little to no synthesis of the evidence base for WRAP outside of the Copeland Center’s internal reviews. Methods & Analysis: The proposed systematic review and meta-analysis aims to investigate the evidence base for Wellness Recovery Action Planning within a mental health context. To do this, a PRISMA 2020 compliant review is proposed using the PRISMA-P statement as a guide to demonstrate the methodology to be undertaken. It outlines the inclusion/exclusion criteria, search terms and databases whilst informing the readership of timescales to complete such actions. Finally, this protocol also addresses issue of bias and quality within included studies. Discussion: This proposed literature review and meta-analysis will synthesise and examine the evidence base for WRAP using a systematic review methodology. It is hoped that this proposed review will identify gaps in the current literature regarding the programme and provide recommendations that will support the reviewers in their further studies, whilst also strengthening the argument for a whole system evaluation of WRAP within an Irish context.

Active Employees! Exploring the Relationship Between Job Characteristics, Perceived Constraints and Participation in Leisure-time Physical Activity
Creators: name: Dunlop, Paul M.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2006

description: Research has suggested that many adults do not participate in enough physical activity to achieve the associated health benefits. Compounding the problem of inactive leisure behaviors, modern workplace duties have also become less active. This study examined patterns of leisure-time physical activity (LTPA) and perceived constraints as related to job characteristics of 382 employees. Less than 8% of participants met the current physical activity recommendations. Females perceived a greater overall effect of constraints than males. Blue-collar workers perceived a greater effect of constraints than white-collar workers. A number of constraints dimensions significantly blocked participation. A number of strategies to encourage LTPA are presented, specifically including the removal or negotiation of time, individual/psychological and accessibility constraint dimensions.

description: The dominant modes of charge transport in variant polar liquid based nanoparticulate colloidal dispersions (dilute) have been theorized. Theories formulating electrical characteristics of colloids have often been found to over or under predict charge transport in dilute suspensions of nanoparticles in polar fluids owing to grossly different mechanistic behavior of concentrated systems. Three major interacting modes with independent yet simultaneous existence have been proposed and found to be consistent with analyses of experimental data. Electric Double Layer (EDL) formation at nanoparticle fluid interface conjugated electrophoresis under the influence of the electric field has been determined as one important mode of charge transport. Nanoparticle polarization due to short range field non-uniformity caused by the EDL with consequent particle motion due to interparticle electrostatic interactions acts as another mode of transport. Coupled electrothermal diffusion arising out of Brownian randomization in presence of the electric field has been determined as the third dominant mode. An analytical model based on discrete interactions of the charged particle fluid domains explains the various behavioral aspects of such dispersions, as observed and validated from detailed experimental analysis. The analysis is also predictive of the dominance and behavior of the three modes with important nanocolloid parameters such as temperature and concentration.
Variability in Hot Carbon-Dominated Atmosphere (hot DQ) White Dwarfs: Rapid Rotation?

description: Hot white dwarfs with carbon-dominated atmospheres (hot DQs) are a cryptic class of white dwarfs. In addition to their deficiency of hydrogen and helium, most of these stars are highly magnetic, and a large fraction vary in luminosity. This variability has been ascribed to nonradial pulsations, but increasing data call this explanation into question. We present studies of short-term variability in seven hot DQ white dwarfs. Three (SDSS J1426+5752, SDSS J2200-0741, and SDSS J2348-0942) were known to be variable. Their photometric modulations are coherent over at least two years, and we find no evidence for variability at frequencies that are not harmonics. We present the first time-series photometry for three additional hot DQs (SDSS J0236-0734, SDSS J1402+3818, and SDSS J1615+4543); none are observed to vary, but the signal-to-noise is low. Finally, we present high speed photometry for SDSS J0005-1002, known to exhibit a 2.1 d photometric variation; we do not observe any short-term variability. Monoperiodicity is rare among pulsating white dwarfs, so we contemplate whether the photometric variability is due to rotation rather than pulsations; similar hypotheses have been raised by other researchers. If the variability is due to rotation, then hot DQ white dwarfs as a class contain many rapid rotators. Given the lack of companions to these stars, the origin of any fast rotation is unclear -- both massive progenitor stars and double degenerate merger remnants are possibilities. We end with suggestions on future work that would best clarify the nature of these rare, intriguing objects.

description: Biological organisms have evolved a wide range of immune mechanisms to defend themselves against pathogens. Beyond molecular details, these mechanisms differ in how protection is acquired, processed and passed on to subsequent generations -- differences that may be essential to long-term survival. Here, we introduce a mathematical framework to compare the long-term adaptation of populations as a function of the pathogen dynamics that they experience and of the immune strategy that they adopt. We find that the two key determinants of an optimal immune strategy are the frequency and the characteristic timescale of the pathogens. Depending on these two parameters, our framework identifies distinct modes of immunity, including adaptive, innate, bet-hedging and CRISPR-like immunities, which recapitulate the diversity of natural immune systems.

description: Objectives: The purpose of this study was to explore the efficacy and feasibility of an innovative, electronically delivered self-management intervention that included daily mindfulness practice, completion of sequential bladder diaries and bladder health education to improve urinary incontinence in older women who lived independently in a retirement community. Methods: This study was a mixed methods pilot study over eight weeks with ten women. The intervention was delivered via a custom made website (http://mindoverbladder-chaicore.vipapps.unc.edu) and included reviewing bladder health education, completion of a 3-day bladder diary at Intervention weeks 1, 5 and 8, and 2 weeks of guided mindfulness practice followed by 6 weeks of mindfulness practice of the participants’ choice. Results: Eight women completed the study. One woman’s data were excluded due to no incontinent episodes at baseline. Five of seven (71%) women had a decrease in daily urinary leakage episodes. A statistically significant decrease (p= 0.041) was found between pre and post scores (with 0 = not at all to 10 = a great deal) on the item, “how much does urinary incontinence affect your everyday life?” Seventy-one percent (N=5) of women reported subjective improvement in incontinence. High scores were found on the feasibility survey and all women said they would recommend the study to other women who have urinary incontinence. Conclusions: The self-management intervention was effective for the participants in improving health related quality of life associated with urinary incontinence and perceived self-efficacy to manage urinary incontinence. The electronically delivered intervention was feasible in the sample population. Improvements should be made in volume control and motivational tools, and developing a website or mobile application that will allow public access. Further research is needed in a larger and diverse population of older women.

description: Safety and reliability are important in the cloud computing environment. This is especially true today as distributed denial-of-service (DDoS) attacks constitute one of the largest threats faced by Internet users and cloud computing services. DDoS attacks target the resources of these services, lowering their ability to provide optimum usage of the network infrastructure. Due to the nature of cloud computing, the methodologies for preventing or stopping DDoS attacks are quite different compared to those used in traditional networks. In this paper, we investigate the effect of DDoS attacks on cloud resources and recommend practical defense mechanisms against different types of DDoS attacks in the cloud environment.

description: In the era of m-Learning, it is found that educational institutions have onus of incorporating the latest technological innovations that can be accepted and understood widely. While investigating the important theme of fast-paced development of emerging technologies in mobile communications, it is important to recognize the extent influence of these innovations using which society can communicate, learn, access information, and, additionally, interact. In addition, the usage of mobile technology in higher education needs not only the pervasive nature of the technology but also its disruptive nature that offers several challenges while incorporation in the area of teaching and learning. Therefore, recently, higher education institutions are looking at various ways of implementing m-Learning strategies, in order to offer solutions, which, in turn, can standardize the process of education and, additionally, replace those traditional didactic courses, focusing on m-Learning endless benefits. Some of the benefits are: the process of learning itself could be self-paced, whereas information could be easier accessed, adding to independent, discovery-oriented learning that becomes more engaging. Applying CMM successfully to design effective incorporation strategies of m-Learning, this research targets formulation of such a maturity model by which the process of m-Learning can be more effective and efficient.

description: Recent years have seen a sharp increase in the use of open source projects by common novice users; Open Source Software (OSS) is thus no longer a reserved arena for software developers and computer gurus. Although user-centered designs are gaining popularity in OSS, usability is still not considered as one of the prime objectives in many design scenarios. In this paper, we analyze industry users perception of usability factors, including understandability, learnability, operability and attractiveness, on OSS usability. The research model of this empirical study establishes the relationship between the key usability factors and OSS usability from industrial perspective. In order to conduct the study, a data set of 105 industry users is included. The results of the empirical investigation indicate the significance of the key factors for OSS usability.

Phonological Priming Effects On Acoustic Duration
Creators: name: Rosa, Elise Camille
Publisher: name: University of North Carolina at Chapel Hill
Year: 2013

description: Spoken words are often reduced in duration upon second mention, due to discourse pressures to reduce given information. However, reduction may also result from facilitation of production processes. Here we ask whether duration is affected by priming from homophones (Exp.1 & Exp. 3) or cohorts (Exp. 2). Participants completed alternating sentence-cloze and picture movement description trials. The target item cloze sentences elicited a homophone or identity prime (Exp. 1) or a cohort or identity prime (Exp. 2) or a homophone prime (Exp. 3). Identity and homophone primes led to shorter word durations (Exp. 1), but there was no such effect of cohort primes (Exp. 2). The effect of homophone primes was eliminated when the relationships between primes and targets were made less obvious (Exp. 3).

description: The systematic review aims are to explore the extent to which mental health literacy practices are included within the AFL academy (through education, resources, information). Additionally, the review aims to determine the gaps in mental health literacy practices within the AFL academy and what needs to be implemented to ensure the mental wellbeing of young female athletes within the academy. This review will be the first to synthesise the available evidence on mental health literacy programs available to female youth athletes in a sporting context. As a result, the review has the potential to make a significant contribution to the mental health challenges faced by young female athletes by informing future practice and developing mental health literacy programs in youth sport.

description: Since the early sixties, our view of radio galaxies and quasars has been drastically shaped by discoveries made thanks to observations of radio sources listed in the Third Cambridge catalog and its revised version (3CR). However, the largest fraction of data collected to date on 3CR sources was performed with relatively old instruments, rarely repeated and/or updated. Importantly, the 3CR contains only objects located in the Northern Hemisphere thus having limited access to new and innovative astronomical facilities. To mitigate these limitations we present a new catalog of powerful radio sources visible from the Southern Hemisphere, extracted from the GLEAM 4-Jy (G4Jy) catalog and based on equivalent selection criteria as the 3CR. This new catalog, named G4Jy- 3CRE, where the E stands for "equivalent", lists a total of 264 sources at declination below -5 degrees and with 9 Jy limiting sensitivity at ~178 MHz. We explored archival radio maps obtained with different surveys and compared then with optical images available in the Pan-STARRS, DES and DSS databases to search for optical counterparts of their radio cores. We compared mid-infrared counterparts, originally associated in the G4Jy, with the optical ones identified here and we present results of a vast literature search carried out to collect redshift estimates for all G4Jy-3CRE sources resulting in a total of 145 reliable z measurements.

Publisher: name: Open Science Framework
Year: 2022
Subjects: subject: Social and Behavioral Sciences

description: Assessing youth psychopathology involves collecting multiple informants’ reports. Yet multi-informant reports often disagree, which necessitates integrative strategies that optimize predictive power. The trait-score approach leverages principal components analysis to account for the context and perspective from which informants provide reports. This approach may boost the predictive power of multi-informant reports and thus warrants rigorous testing. We tested the trait score approach using multi-informant reports of adolescent social anxiety in a mixed clinical and community sample of adolescents (N = 127). The trait score incrementally predicted observed social anxiety (βs = 0.47–0.67) and referral status (odds ratios = 2.66–6.53) above and beyond individual informants’ reports and a composite of informants’ reports. The trait score predicted observed behavior at magnitudes well above those typically observed for individual informants’ reports of internalizing psychopathology (i.e., rs = .01–.15). Findings demonstrate the ability of the trait score to improve prediction of clinical indices and potentially transform widely used practices in multi- informant assessments.

description: Methodological innovations have allowed researchers to consider increasingly sophisticated statistical models that are better in line with the complexities of real world behavioural data. However, despite these powerful new analytic approaches, sample sizes may not always be sufficiently large to deal with the increase in model complexity. This poses a difficult modeling scenario that entails large models with a comparably limited number of observations given the number of parameters (also known as the “small n, large p” problem). We here describe a particular strategy to overcoming this challenge, called regularization. Regularization, a method to penalize model complexity during estimation, has proven a viable option for estimating parameters in this small n, large p settings, but has so far mostly been used in linear regression models. Here we show how to integrate regularization within structural equation models, a popular analytic approach in psychology. We first describe the rationale behind regularization in regression contexts, and how it can be extended to regularized structural equation modeling (Jacobucci, Grimm, & McArdle, 2016). Our approach is evaluated through the use of a simulation study, showing that regularized SEM outperforms traditional SEM estimation methods in situations with a large number of predictors, or when sample size is small. We illustrate the power of this approach in a N=627 example from the CAM-CAN study, modeling the neural determinants of visual short term memory. We illustrate the performance of the method and discuss practical aspects of modeling empirical data, and provide a step-by-step online tutorial.

description: Osteoarthritis (OA) is a prevalent joint degenerative disease and a leading cause of disability in elderly population. Among related risk factors of OA, muscle weakness and obesity were considered as two major ones. Sarcopenia, a relatively new syndrome which is referred to age-related degenerative loss of skeletal muscle mass and strength, has attracted great attention by academic circle in view of its association with increased adverse outcomes. Several studies have investigated the relationship between OA and sarcopenia. However, literature results were controversial. Therefore, the purpose of this study is to systematically examine the existing literature on the associations between sarcopenia and OA. The results of this report will be disseminated after peer review and publication.

description: The Metamorphosis Project must break through negative stereotypes of adolescents with messages that inspire policy maker and public support of adolescent health. The purpose of this master's thesis is five-fold: (1) to understand how the American public views teens, (2) to review literature that presents best practices for framing teens to achieve organizational goals, (3) to dissect existing messages of organizations nationwide that frame teens (and to propose framing models), (4) to use best practices and framing models to compose messages for The Metamorphosis Project, and (5) to test the messages with members of the target audience. Findings from the first three phases suggested four key frames, strengths and positive outcomes, social incentives, economic incentives, and adolescence is a developmental stage, which were used to develop messages.

New journal for the promotion of Vietnamese environmental research
Creators: name: Stefan, Catalin
Publisher: name: Journal of Vietnamese Environment
Year: 2011

description: The Vietnamese science and high education system plays a major role in the country’s social and economical development. Due to a mixed influence of international education systems, the contribution of the Vietnamese research to the international scientific landscape is still modest. Over the past decades, the most scientific programmes focused mostly on rather theoretical sciences and less on applied sciences. The results are reflected by a rather low rate of international publications on experimental science. Together with the country’s efforts on the efficient use of natural resources, there is an urgent demand for strengthening the scientific activity on environmental sciences. The new Journal of Vietnamese Environment was created to respond to the increasing interest in environmental research. The journal was founded as part of an academic network initiated by the Dresden University of Technology in the framework of Vietnamese-German cooperation programs on training and education. With multidisciplinary fields of interest and several types of manuscripts, the journal has a predominant academic character, the submission of manuscripts is open to students, graduates, researchers and staff members of research and academic institutions, as well as to any individual willing to disseminate the knowledge about the management of Vietnamese environment. Hệ thống khoa học và giáo dục đại học Việt Nam đóng vai trò quan trọng trong sự phát triển kinh tế và xã hội của đất nước. Trong xu hướng giao thoa mạnh mẽ giữa các hệ thống giáo dục quốc tế, đóng góp của các nhà nghiên cứu ở Việt Nam cho cộng đồng khoa học quốc tế còn khiêm tốn. Trong những thập niên qua, hầu hết các hoạt động khoa học tập trung vào khoa học lý thuyết hơn là các lĩnh vực khoa học ứng dụng. Điều này đã được phản ánh qua tỷ lệ khá thấp các ấn phẩm quốc tế về khoa học thực nghiệm. Cùng với những nỗ lực của đất nước để sử dụng hiệu quả các nguồn tài nguyên thiên nhiên, một nhu cầu cấp bách đặt ra là tăng cường các hoạt động nghiên cứu về khoa học môi trường. Tạp chí Môi trường Việt Nam ra đời nhằm hưởng ứng sự quan tâm ngày một gia tăng trong nghiên cứu môi trường. Tạp chí được thành lập như một phần của mạng lưới học thuật được đề xuất bởi Trường Đại học Tổng hợp Kỹ Thuật Dresden trong khuôn khổ chương trình hợp tác Việt Nam - CHLB Đức về đào tạo và giáo dục. Với mối quan tâm đa ngành và đa dạng trong ấn phẩm, tạp chí chủ yếu mang tính học thuật, cơ hội gửi đăng bài viết mở rộng cho cả sinh viên, kỹ sư / cử nhân, nghiên cứu viên và các thành viên của Viện nghiên cứu và giáo dục, các cá nhân có mong muốn phổ biến kiến thức về quản lý môi trường ở Việt Nam.

description: Syphilis is among the most frequent sexually transmitted infections (STI) worldwide and figures out as one of the leading preventable and treatable causes of infant morbidity and mortality. Congenital syphilis, which is mother-to-child transmitted during pregnancy, can lead to several fetal adverse outcomes, as stillbirths, neonatal deaths, preterm births, low birth weight, and congenital infection in infants. World Health Organization (WHO) has been reaching encouraging results in response to the global initiative to eliminate vertical transmission of syphilis. In 2016, for example, while the prevalence of maternal syphilis corresponds to 0,10% in Europe, it was 0,86% in the Americas and reached 1,52% in Africa. In parallel, rates of congenital syphilis reached 19, 339, and 1,119 per 100,000 live births, respectively, in the same regions. Globally, indigenous peoples have low health standards, marginalization, adverse environmental, sanitary, and socioeconomic conditions, and limited healthcare access. The high burden of infectious diseases, high infant and maternal mortality, and low birth weight are among the leading health problems in those populations. It indicates that maternal and congenital syphilis might compose indigenous populations' adverse maternal and child health profiles in several world regions. Disparities in STI and HIV/AIDS burden between indigenous and non-indigenous people are a growing public health concern. However, maternal syphilis and congenital syphilis in these populations remain invisible. The scarcity of studies on this topic remains an obstacle to analyze racial-ethnic inequities in the burden of disease, identify its determinants, and define priority groups for social health and public policies implementation. This study aimed to explore the breadth of the literature, map updated evidence, and identify knowledge gaps on maternal and congenital syphilis in Indigenous Peoples worldwide, to inform future research and social and public health policies.

description: \noindent Let $I$ be an ideal of the ring of formal power series $\bK[[x,y]]$ with coefficients in an algebraically closed field $\bK$ of arbitrary characteristic. Let $Φ$ denote the set of all parametrizations $φ=(φ_1,φ_2)\in \bK[[t]]^2$, where $φ\neq (0,0)$ and $φ(0,0)=(0,0)$. The purpose of this paper is to investigate the invariant \[ \Lo(I)=\sup_{φ\in Φ}\left(\inf_{f\in I} \frac{\ord f \circ φ}{\ord φ}\right) \] \noindent called the {\it Łojasiewicz exponent} of $I$. Our main result states that for the ideals $I$ of finite codimension the Łojasiewicz exponent $\Lo(I)$ is a Farey number i.e. an integer or a rational number of the form $N+\frac{b}{a}$, where $a,b,N$ are integers such that $0

description: The Bakersville, NC eclogite bodies in the southern Appalachians record peak metamorphic conditions of the Taconic orogeny. These high-pressure rocks are surrounded by amphibolite-facies rocks of the Ashe Metamorphic Suite. The eclogite zircons record ages of 460.7 ± 3.2 Ma, temperatures of 703-775 °C, and the zircon REE patterns indicate that they grew at eclogite-facies conditions. The amphibolite zircons record ages of 415 ± 3.8 Ma, temperatures of 614-669 °C, and their REE patterns indicate that the zircons did not grow in the presence of garnet, which are present at eclogite conditions. These differences suggest that the amphibolites are not retrograded eclogite and that the Bakersville eclogite was emplaced into lower-grade rocks during its exhumation, consistent with either driven cavity flow or plunger-driven exhumation models. The Silurian-Devonian age of the amphibolite zircon may record crustal thickening and burial related to post-Cherokee orogeny movement along the Burnsville fault.

description: Cerebrolysin is recommended in clinical practice guidelines across several continents. Previous meta-analyses on Cerebrolysin safety profile provided inconsistent results. This applies especially to the two largest most recent meta-analyses: Bornstein et al. 2018, including 1879 patients from nine randomized-controlled trials (RCTs), and the review of Ziganshina et al. 2020, including 1601 patients from seven RCTs. To resolve the reported discrepancies, the present meta-analysis aimed to explore the safety profile of Cerebrolysin, using the maximum amount of evidence available.
Mass transfer and magnetic braking in Sco X-1

description: Sco X-1 is a low-mass X-ray binary (LMXB) that has one of the most precisely determined set of binary parameters such as the mass accretion rate, companions mass ratio and the orbital period. For this system, as well as for a large fraction of other well-studied LMXBs, the observationally-inferred mass accretion rate is known to strongly exceed the theoretically expected mass transfer rate. We suggest that this discrepancy can be solved by applying a modified magnetic braking prescription, which accounts for increased wind mass loss in evolved stars compared to main sequence stars. Using our mass transfer framework based on {\tt MESA}, we explore a large range of binaries at the onset of the mass transfer. We identify the subset of binaries for which the mass transfer tracks cross the Sco X-1 values for the mass ratio and the orbital period. We confirm that no solution can be found for which the standard magnetic braking can provide the observed accretion rates, while wind-boosted magnetic braking can provide the observed accretion rates for many progenitor binaries that evolve to the observed orbital period and mass ratio.
