Published: December 2024

Abstract
With the growing energy demand both domestically and internationally, significant progress has been made in the construction of long-distance oil and gas pipelines and the maintenance of in-service pipelines, which has simultaneously raised higher requirements for automatic welding equipment, process methods, and efficiency. In recent years, automatic welding equipment used for oil and gas pipeline welding has predominantly employed arc-tracking technology, which meets the requirements for fully automatic fill and cap welding in standard groove configurations with stable welding quality. However, in hot-work welding processes for in-service pipeline maintenance and emergency repairs, manual alignment and cutting result in irregular weld seams, leading to poor performance of automatic welding equipment and, consequently, reliance on manual welding, which is inefficient. To address this, a specialized automatic welding machine with a laser vision weld seam tracking system was designed for welding irregular weld seams in long-distance oil and gas pipelines. Research was conducted on its mechanical system, control system, welding system, and tracking process. The specialized machine primarily consists of a power supply box, control box, industrial computer, laser sensing system, and welding carriage. During welding, the laser sensor measures three-dimensional information such as the seam size and center offset in real time along the direction of the welding carriage movement and feeds it back to the controller through the communication system of the machine. The main control system receives the information and adjusts the welding torch’s movement and welding process parameters through internal tracking control algorithms. Welding experiments were conducted on X80 steel V-groove welds of long-distance oil and gas pipelines. The results show that the welding machine can accurately identify the weld seam width, center offset, and height offset, and adjust the welding torch actions and parameters accordingly, achieving fully automated adaptive tracking welding. The precision of single torch oscillation tracking during welding can reach 0.5 mm, and the welding quality is good, meeting the requirements for single-layer single-pass fill welding, and multi-pass welding of irregular pipeline weld seams.

Abstract
This study focuses on the quantum magnetic properties and entanglement of trinuclear C84H75N12Ni3O3 · 3(ClO4) · 6.5(C3H7NO) and tetranuclear C24H54Cl2N10Ni4O19. This study compares experimental data with exact theoretical calculations of magnetic susceptibility as a function of temperature, revealing excellent agreement. We observe a correlation between magnetization jumps, magnetic susceptibility peaks, and logarithmic negativity plateaus, in response to changes in external magnetic fields for trinuclear and tetranuclear Ni ion complexes at low temperatures. These observations require further experimental measurements in external magnetic fields at low temperatures.

Abstract
Myocardial infarction (MI) remains a leading cause of mortality worldwide, posing a significant challenge to healthcare systems. The limited regenerative capacity of cardiac tissue following MI results in chronic cardiac dysfunction, highlighting the urgent need for innovative therapeutic strategies. In this study, we explored the application of a multidimensional nanofibrous hydrogel for myocardial regeneration. We developed a composite hydrogel system by integrating fibrin, polycaprolactone (PCL), and alginate. In this system, fibrin supported cell proliferation and significantly enhanced angiogenesis when combined with human umbilical vein endothelial cells (HUVECs). PCL contributed to the alignment of encapsulated cells, improving their organization within the scaffold. Adipose-derived stem cells (ADSCs) were encapsulated within the hydrogel for their versatile regenerative potential, while C2C12 cells were incorporated for their ability to form muscle tissue. Additionally, the inclusion of alginate not only enhanced the mechanical properties of the hydrogel to better match the biomechanical demands of cardiac tissue but also played a critical role in reducing the immune response, thereby improving the system’s biocompatibility. This study presents an advanced platform for myocardial regeneration using a nanofibrous hydrogel system designed to meet the dual requirements of mechanical robustness and cellular compatibility essential for cardiac tissue engineering. The triculture system, consisting of ADSCs, C2C12 cells, and HUVECs, harnesses the regenerative capabilities of each cell type, promoting both angiogenesis and tissue regeneration. This comprehensive approach addresses the immediate needs for cellular survival and integration while effectively overcoming long-term mechanical and immunological challenges.
Uncertainty
Authors: Sytch Maxim 
Published: December 2024

Abstract
This chapter explores the first enabling market condition of supplier-induced demand: uncertainty. The modern knowledge-based economy, characterized by increasing abstraction and complexity, breeds a palpable sense of uncertainty. This uncertainty manifests in various forms, such as problem, action, and outcome uncertainty. Consequently, organizations grapple with understanding the situation, determining the optimal course of action, and evaluating potential outcomes. In response, professional service firms have emerged as elite experts adept at navigating this uncertainty. Consequently, companies often delegate complex decision-making to these firms, regarding them as knowledgeable and reputable experts. However, this reliance also exposes organizations to the influence of professional service firms, potentially leading to supplier-induced demand. Moreover, professional service firms may unintentionally exacerbate the uncertainty their clients face, further solidifying their clients’ dependence on external expertise. These dynamics highlight uncertainty as one of the primary enablers of supplier-induced demand.
The Emergence of Supplier-Induced Demand
Authors: Sytch Maxim 
Published: December 2024

Abstract
The fusion of the commercial institutional logic and the resulting internalized professional identity leads to supplier-induced demand through three key biases. The first bias is the bias for action, in which professionals tend to lean toward taking action rather than remaining inactive in situations of uncertainty. The second bias is the familiarity bias, which prompts professionals to promote the expertise, products, and services they are familiar with, even if they may not be an appropriate solution for the client’s problem. The final bias is the agreement bias, wherein professionals and clients agree upon a course of action that neither genuinely supports. Frequent social interactions and embedded relationships between buyers and suppliers, often facilitated by geographical proximity, make proximate professional service providers the most likely sources of supplier-induced demand. Under enabling market conditions and the prevailing commercial institutional logic, geographically proximate relationships become potent channels for social influence toward supplier-induced demand.
Can I have fries with that? Context-dependent foraging behavior in urban and rural American crows
Authors: Merz Margaret R , Cote Sophie , Weinberg Rachel , Malley Timary , Townsend Andrea K 
Published: December 2024

Abstract
Behavioral flexibility and the ability to respond appropriately to anthropogenic cues that signal potential threats or rewards may promote the success of wild animals in the urban environment. Here, we examine the behavioral responses to anthropogenic cues of free-living American crows (Corvus brachyrhynchos), an opportunistic scavenger and common urban exploiter. Specifically, we tested the hypotheses that crows would more readily approach (1) novel objects and anthropogenic food when in close proximity to trash cans, and (2) paper bags with hidden food rewards when closer to a McDonald’s restaurant, due to their associations of food with these cues. In addition, we examined the preference of crows for bags marked with a McDonald’s logo vs. unmarked bags, hypothesizing that crows closer to McDonald’s would be more likely to approach the labeled bag because of its familiarity. Consistent with our expectations, crows exhibited a lower approach latency to anthropogenic food and novel objects in close proximity to trash cans. Likewise, they were more likely to approach paper bags when in proximity to a McDonald’s restaurant, but they showed no preference for bags with a McDonald’s logo. Overall, we found evidence that the foraging behavior of crows varied in the presence of specific anthropogenic cues and that these responses depended on their probable cue familiarity. Their ability to use anthropogenic cues specific to the local environment, combined with their exploitation of human food resources, likely contributes to the success of the American crow in the city.
‘I had the full support of my family! This family support tops everything else’: Facilitators for Arabs with disabilities in Israel to lead meaningful, independent, and dignified lives by applying self-efficacy theory

Published: December 2024

Abstract
This study aims to explore the significance of facilitators for Arabs with disabilities to lead meaningful, independent, and dignified lives by applying self-efficacy theory and the ecological model in a resource-poor environment. Semi-structured in-depth interviews of fifteen Arabs with physical, visual, and psychiatric disabilities who live in the community were conducted. Thematic analysis revealed two major themes, focusing on facilitators for meaningful, independent, and dignified lives: (1) Self-efficacy, resilience, and strength and (2) Sources of Self-efficacy, most of which were situated at the microsystem level. Studying the available facilitators for Arabs with disabilities living in Israel at the micro level underscores how each facilitator is vitally important for success. The authors recommend (1) localized, family-based, or community training in the availability, acquisition, or creation of services and rights; (2) training for families and local communities to nurture self-efficacy, resilience, and strength; and (3) holistic intervention by social workers is required.
Allograft versus autograft ACL reconstruction in skeletally immature patients: a systematic review
Authors: Migliorini Filippo , Pilone Marco , Schäfer Luise , Bertini Francesca Alzira , Giorgino Riccardo , Maffulli Nicola 
Published: December 2024

Abstract

Introduction
Anterior cruciate ligament (ACL) injuries in children and adolescents with open physes are common.

Areas of agreement
Evidence of ACL reconstruction using allografts in children with open physes is limited.

Areas of controversy
Whether the outcomes of ACL allograft reconstruction in children and adolescents with open physes are superior to autograft ACL reconstruction is unclear, with contrasting evidence.

Source of data
In October 2024, the Web of Science, PubMed, and Embase were accessed with no additional filters. Only clinical investigations evaluating ACL reconstruction in children or adolescents with open physes were eligible. Only studies reporting a minimum length of 24 months of follow-up were included.

Areas timely for developing research
Children who undergo allograft ACL reconstruction demonstrate similar functional outcomes to those who undergo autograft ACL reconstruction. Although allografts allow a faster return to sport, the greater laxity, the reduced activity level, and the higher failure and reoperation rates make their use dubious as a first-choice option for ACL reconstruction in skeletally immature patients.

Authors: Gao Jia , Li Qiuting , Huang Haiying , Yu Siguang , Qiu Yanping , Liang Yanping , Lan Lizhen , Li Lili 
Published: December 2024

Abstract

Background
Vitiligo is a clinically prevalent acquired skin disorder characterized by depigmentation. Currently, the therapeutic options for vitiligo are restricted, and numerous issues exist, such as a prolonged treatment course, unsatisfactory therapeutic efficacy, adverse reactions and a high propensity for recurrence after treatment cessation.

Objectives
To assess the safety and efficacy of combined treatment involving oral tofacitinib citrate (TC) and a 308-nm excimer laser (EL), with the aim of discovering a rapid and effective treatment approach to minimize the side-effects of various drugs.

Methods
In total, 63 patients with progressive vitiligo and a Vitiligo Disease Activity Score of 4 from January 2022 to January 2024 were enrolled and divided into three groups. The three groups were: the TC combined with 308-nm EL and methylprednisolone treatment group (group 1); the TC and 308-nm EL treatment group (group 2); and the methylprednisolone alone treatment group (group 3). The treatment was continued for 24 weeks, and an assessment of therapy outcomes was performed.

Results
When TC was combined with 308-nm EL and methylprednisolone treatment (group 1), the effect was more rapid than in the other two groups. When TC was combined with 308-nm EL (group 2), it had a more favourable treatment effect than that of methylprednisolone alone (group 3), despite having a slower onset of effect. After 24 weeks of treatment, there was no significant difference between group 1 and group 2 in terms of the total response rate or significant response. However, when only methylprednisolone treatment was applied, the effect was relatively slow and ineffective.

Conclusions
This study confirmed a rapid and effective treatment of vitiligo was achieved through a combination of TC and 308-nm EL. No serious adverse reactions were reported, and therefore this could potentially offer an optimal treatment plan for patients with vitiligo.
Testing Hubel and Wiesel’s “ice-cube” model of functional maps at cellular resolution in macaque V1
Authors: Zhang Sheng-Hui , Tang Shi-Ming , Yu Cong 
Published: December 2024

Abstract
Hubel and Wiesel’s ice-cube model proposed that V1 orientation and ocular dominance functional maps intersect orthogonally to optimize wiring efficiency. Here, we revisited this model and additional arrangements at both cellular and pixel levels in awake macaques using two-photon calcium imaging. The recorded response fields of view were similar in size to hypercolumns, each containing up to 2,000 identified neurons and representing full periods of orientation preferences and ocular dominance. We estimated each neuron/pixel's orientation, ocular dominance, and spatial frequency preferences, constructed respective functional maps, computed geometric gradients of feature preferences, and calculated intersection angles among these gradients. At the cellular level, the intersection angles among functional maps were nearly evenly distributed. Nonetheless, pixel-based maps after Gaussian smoothing displayed orientation-ocular dominance and orientation–spatial frequency orthogonality, as well as ocular dominance–spatial frequency parallelism, in alignment with previous results, even though the trends were weak and highly variable. However, these Gaussian smoothing effects were not observed in cellular maps, indicating that the pixel-based trends may not accurately represent the relationships among feature-tuning properties of V1 neurons. We suggest that the widely distributed intersections among cellular maps can ensure that multiple stimulus features are represented within a hypercolumn, and no pair of features is represented with the least economical wiring (e.g. parallel intersections).

Authors: Wee Liang En , Lim Jue Tao , Goel Mayank , Malek Muhammad Ismail Abdul , Chiew Calvin J , Ong Benjamin , Lye David Chien Boon , Tan Kelvin Bryan 
Published: December 2024

Abstract

Background
Vaccination has been shown to attenuate the risk of postacute sequelae following severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. However, no prior population-based studies have evaluated if updated bivalent boosters reduce risk of postacute sequelae following Omicron variant infection, versus ancestral vaccines.

Methods
National databases were utilized to construct a population-based cohort of adult individuals infected during Omicron-predominant transmission. Risk and excess burden (EB) of prespecified multiorgan new-incident diagnoses at 31–365 days post–SARS-CoV-2 infection were compared between individuals who received prior bivalent boosters and those boosted with ancestral messenger RNA (mRNA) vaccines, using competing-risks regression.

Results
A total of 1 080 348 vaccine-breakthrough infections after an ancestral mRNA booster were contrasted against 9824 vaccine-breakthrough infections following a bivalent mRNA booster. There was an estimated 37.8% (hazard ratio [HR], 0.62 [95 confidence interval {CI}, .53–.73]) decrease in risk and lower overall EB per 1000 (−28.73 [95% CI, −40.47 to −16.99]) of any postacute sequelae, as well as a 39.9% (HR, 0.62 [95% CI, .52–.73]) decrease in risk and lower EB (−22.95 [95% CI, −32.71 to −13.19]) of any postacute neurological sequelae, among individuals who received prior bivalent boosters, versus those boosted with ancestral mRNA vaccines. Specifically, there was reduced risk of thrombotic disorders (HR, 0.54 [95% CI, .29–.99]), episodic neurological disorders (HR, 0.55 [95% CI, .43–.72]), movement disorders (HR, 0.57 [95% CI, .47–.70]), and autoimmune vasculitis (HR, 0.54 [95% CI, .29–.99]) 31–365 days postinfection among those who received prior bivalent boosters, versus those boosted with ancestral mRNA vaccines.

Conclusions
Boosting with updated bivalent mRNA vaccines was associated with greater attenuation of risk for postacute sequelae following Omicron variant infection, compared with ancestral mRNA boosters.
Distorted Technology Adoption
Authors: Ayerst Stephen 
Published: December 2024

Abstract
To what extent do firm-level institutional distortions drive cross-country technology differences? I develop a quantitative model of technology adoption in which heterogeneous firms adopt technology depending on their underlying productivity and institutional environment. The institutional environment is represented by size-dependent firm-level wedges on revenues that distort firm decisions. The model is calibrated to match the US firm employment distribution and the average adoption length of new technologies. In less developed countries, measured size-dependent distortions hinder highly productive firms, delaying the adoption of new technologies as these firms are (otherwise) early adopters. Measured differences in size-dependent distortions explain around half of the observed cross-country variation in adoption lags. Additionally, distorted technology adoption over doubles the aggregate productivity loss compared to static misallocation alone.

Published: December 2024

Abstract
Pod dehiscence facilitates seed dispersal in wild legumes while indehiscence is a key domestication trait in cultivated ones. However, the evolutionary genetic mechanisms underlying its diversity are largely unclear. In this study, we compared transcriptomes of two warm-season (Glycine spp. and Phaseolus spp.) and two cool-season (Pisum spp. and Medicago ruthenica) legumes in analysis of dehiscent and indehiscent pod genotypes. Differentially expressed genes in AP2/ERF-like transcription factors and seven structural gene families, including lactoperoxidase, laccase, and cellulose synthase-interactive proteins, which are involved in secondary cell wall component accumulation, were identified to exert key roles in pod dehiscence variation. In accordance with this, higher lignin and cellulose contents were observed in pod secondary cell wall of dehiscent accessions of soybean and pea; however, the variation patterns of lignin polymers in soybean (accumulation) and pea (proportion) differed between dehiscent and indehiscent pods. Moreover, genome-wide comparative analysis revealed that orthogroups represented &lt;1% of all identified differentially expressed genes could be traced among the four genera of legumes, while recruiting paralogous members may constitute the genetic robustness of legume pod dehiscence. This study compared the genetic mechanism among several legumes in pod dehiscence formation and revealed a compensating role of paralogous redundancy of involved gene families in seed dispersal, which can guide crop breeding.

Published: December 2024

Abstract
It is essential to provide the community with evidenced-based care to optimize healthcare outcomes; more specifically, women in underserved communities with limited access to healthcare services. The purpose of this research was to determine the effectiveness of a single virtual movement-based pelvic health education session on women’s pelvic health knowledge, adherence to performing pelvic exercises and confidence in performing the exercises. Forty-two female participants were recruited in Western Arkansas. Participants completed an online pre-session (pre) questionnaire and then received a single virtual education session led by a healthcare provider trained in pelvic health. A post-session (post-1) questionnaire was completed by each participant as well as a 1-month follow-up (post-2) questionnaire. Thirty-five women completed all three questionnaires and pelvic health knowledge, adherence to pelvic floor exercises and confidence in performing pelvic floor exercises were assessed. After the participants completed the post-2 questionnaire, they were invited for a semi-structured interview and 13 women participated. Results of this study suggest pelvic health knowledge increased after a single session of movement-based education, and this was retained 1 month later. Adherence and confidence to perform the exercises did not change; however, learning about pelvic health in a virtual movement-based method was a positive experience and initiated an eagerness to learn more about pelvic health. Pelvic health education can be implemented in a virtual approach to engage women in underserved communities to learn more about pelvic health through a positive experience for an educational baseline to gain healthcare autonomy.
