“The Voice of Agitation Should Roll across the Broad Atlantic”
Authors: Graden Dale
Published: November 2024

Scholars have provided impressive analyses of the transatlantic slave trade to the Americas and its demise over the past four decades, this led by contributions to the Trans-Atlantic Slave Trade Database (
https://www.slavevoyages.org/
). England played a decisive role in the suppression of that traffic after prohibition of British participation in 1808, this partly achieved by British interceptions of slave vessels by its West Africa Squadron (1819–1867) and the establishment of Courts of Mixed Commission for the Abolition of the Slave Trade (1819–1871). Given a North Atlantic Ocean current clockwise gyre and South Atlantic counterclockwise gyre, a major northern slave vessel route connected Africa to the Caribbean and a second southern route connected Africa to Brazil.1 Africans disembarked in the Caribbean had diverse origins in West Africa (Sierra Leone, Ghana, Togo, Nigeria) and West Central Africa (Congo, Angola). Brazil received fewer Africans from West Africa (there was a long-term connection between Benin and Bahia), large numbers of African slaves from West Central Africa and a small number from Southeast Africa (Mozambique) at or near Rio de Janeiro. Language difference (Spanish, French, English, Dutch, Danish in the North Atlantic, Portuguese in the South Atlantic) contributed to a conceptual separation of those two regions, particularly evident in historiographies related to slavery and abolition. The Scottish diplomat David Turnbull was one of the few observers of the nineteenth century who connected Caribbean islands with Brazil. Turnbull asserted to the British Foreign Office that subaltern resistance by slaves and free blacks in both the British and non-British Caribbean could aid in England’s quest to extinguish the transatlantic slave trade. Turnbull organized a petition campaign in Jamaica in the late 1840s to pressure England’s Foreign Office to pursue more aggressive actions at sea and on land to halt slave disembarkations in Cuba and Brazil. Foreign Secretary Lord Palmerston’s positive response combined with slave resistance in Brazil contributed to Brazil’s imperial government decision to act decisively to halt further slave disembarkations in 1850–1851.

Published: November 2024

Involuntary celibates, or incels, have been of heightened interest to scholars and practitioners due to their ongoing engagement in misogynistic and violent discourse. The incel subculture is complex, requiring unique strategies to develop effective interventions. The present study investigates patterns in incels’ online posting behaviors and whether acceptance of subcultural beliefs is reflected in variations of user engagement and posting behaviors over time. A sample of postings are drawn from a well-known incel-moderated forum and analyzed using group-based trajectory modeling. The results demonstrate that three distinct posting trajectory groups are present. The findings demonstrate heterogeneity among users’ posting behaviors in the forum over time and suggest that variation may be a reflection of users’ subcultural beliefs.

Published: November 2024

This research endeavors to utilize electrophoretic deposition (EPD) to coat copper (Cu) pipes with graphene oxide (GO) nanosheets, aiming to bolster their resistance against corrosion. To achieve this, a stable aqueous colloidal suspension of GO was meticulously prepared via liquid exfoliation in deionized water. This suspension served as an electrolytic solution for EPD. The EPD process involved the meticulous application of varied operational parameters such as deposition time, applied voltage, and GO nanosheet concentration to facilitate anodic deposition on the copper pipe’s surface. To gauge the efficacy of the GO coating, evaluations were conducted to assess adhesive force and stabilization using specialized coating adhesion scratch testing equipment. Further analysis of the resulting film on the Cu pipe was executed employing X-ray diffraction (XRD), scanning electron microscopy (SEM), Raman spectroscopy, and Fourier transform infrared spectroscopy (FT-IR). These methods provided detailed insights into the characteristics and properties of the GO material post-deposition. The study yielded noteworthy outcomes, revealing the achievement of a uniform, unbroken, and consistent coating film on the Cu pipe. This was accomplished by employing specific parameters as 60 s of deposition time, a GO concentration of 0.5 mg/mL, and a voltage of 20 V. Impressively, when subjected to a corrosive solution containing 3.5% sodium chloride, the corrosion protection exhibited a remarkable twofold enhancement compared to untreated copper tubing, boasting an efficiency (η) of 90.48%. These findings suggest that the Cu pipe, coated with GO using the EPD technique, holds significant promise for utilization in demanding industrial settings susceptible to corrosion challenges.

Authors: Rojs Lucia , Krohne Nina , Gomboc Vanja , Lavrič Meta , De Leo Diego , Poštuvan Vita
Published: November 2024

The aim of this study was to explore public attitudes toward medically assisted dying, focusing on the role of socio-demographic factors, mental health conditions, and personal experiences. Data were collected via an online panel in Slovenia, which consisted of 567 participants (53.1% men) aged 18 years and older. The majority of respondents supported medically assisted dying for terminally ill individuals (76.4%) and expressed willingness to support a loved one’s decision (72.8%). The analysis indicated that psychosocial factors and personal experiences predict attitudes toward medically assisted dying. In particular, women, individuals with poorer physical and psychological health and individuals in better environmental conditions were more likely to have positive attitudes. In contrast, individuals who had experienced the loss of a loved one were more likely to oppose it. These findings suggest the need for further research to deepen understanding of the factors that predict attitudes toward medically assisted dying.
Actual, Potential, and Non-Participants: Advancing the Differential Analysis of Protest Participation
Authors: Mercea Dan , Santos Felipe G. , Hoffmann Matthias
Published: November 2024

In this article, we contribute to the analysis of protest participation on a gradient from non- to actual participation. Using survey data from six European countries, we take the analysis beyond a binary differentiation between participants and non-participants. We evidence a participation gradient underpinned by a combination of social and political variables and separate patterns that allow for distinctions between non-, potential, and actual protesters. We establish that some factors have a gradual, linear, relation to protest participation, increasing the likelihood of moving from non-participation to potential participation and from potential to actual participation. Second, we find evidence of a punctuated rather than a linear participation gradient in as far as a range of variables distinguish protesters and potential protesters from non-participants but do not differentiate them from each other. Our findings provide practical insights into mobilization pathways while also inviting further research into intervening factors influencing protest behavior.
Catholicism, religious diversity, and syncretism in the Latin American religious field and the immigrant religion contribution
Authors: ORELLANA Felipe
Published: November 2024

This article seeks to recognise the role of immigrant religion in the current Chilean religious scenario. The analysis considers two approaches in the study of Latin American religion: (1) the monopoly that Catholicism has had since the colonial period to the recent increase of religious pluralism (i.e. the spread of Protestantism – Pentecostalism – and other religious expressions) and (2) the religious syncretism and heterodox religious practices outside the official religion. In addition, the research identifies a third trend: the role of immigrant religion in the revitalisation and cultural diversification of national parishes. This latter approach has been understood as a current phenomenon that produces national parishes integrated by Chileans and immigrants in the Chilean context.

Authors: Wu Xiufa , Zhang Jing , Wei Chunsheng
Published: November 2024

Objective: Given the rarity of adult hypopharyngeal vascular anomalies (AHVAs), no systematic studies are currently available. The aim of this study is to explore therapeutic strategies for AHVAs and determine the optimal timing for surgery in their treatment. Methods: We conducted a retrospective analysis of the data from patients diagnosed with AHVAs who underwent treatment using either bleomycin injection or excision methods in our department between September 2013 and November 2022. The study evaluated the curative efficacy, factors influencing efficacy, the size of AHVAs, and the selection of surgical methods. Results: A total of 23 adult patients underwent 30 distinct procedures. The study revealed that the choice of surgical methods significantly impacted therapeutic outcomes, with potassium-titanyl-phosphate laser, carbon dioxide (CO2) lasers, low-temperature plasma, and Holmium laser proving effective in treating AHVAs. The therapeutic effect was found to be worse for AHVAs involving multiple subzones compared to those with single subzone invasion. Notably, 3 patients underwent 2 surgeries: the first involved a bleomycin injection, followed by a complete surgical excision. Conclusions: The findings of our study emphasize the superior outcomes achieved through surgical excision when AHVAs are clearly delineated. Furthermore, we recommend opting for surgical excision after a reduction of AHVAs induced by bleomycin injection.

The Affective Micropolitics of Craftivism: Organizing social change through the minor gesture
Authors: Vachhani Sheena J. , Bell Emma , Bristow Alexandra
Published: November 2024

While craft foregrounds the material, embodied and affective nature of making practices, it also has capacities as a political resource which recognizes the value of everyday materiality in creating the conditions for change to emerge. In this article, we explore these possibilities by focusing on craftivism, a diffuse social movement that uses traditional craft skills of hand making to address a wide range of complex societal and organizational causes and challenges. We draw on an empirical study of craftivists to explore how they use craft as a political resource to organize change by generating affective relations between people and material objects in physical and online spaces. We argue that minor gestures of craft, developed through practices of reclaiming historically defined, domestic and feminine handcrafts, constitute a distinctive repertoire of contention and enable craftivism as a journey of change in the minor key. This helps us to think about change differently, where making is a form of change itself that is at least as significant as the destination of the resulting change. We thus draw attention to activism that subverts traditionally oppositional approaches to organizing resistance and surfaces complex coalitions directed towards individual, community and societal transformation. Such craft practices subversively bring together the politics of the domestic sphere with broader grand challenges, thereby subtly altering how we perceive traditional means of political engagement and different forms of activism. Our contribution offers deeper understanding of the affective potential of minor gestures of craft from the lived experience of those who use craft as a form of organizing change through creative, material and affective practice. Affective micropolitical acts such as the habits, rhythms and routines of craft are generative in the sense that they attune us to social change in the minor key.
Aesthetics as a Racial Regime of Modernity: Rizvana Bradley, Anteaesthetics: Black Aesthesis and the Critique of Form
Authors: Pugh Jonathan
Published: November 2024

Taking aesthetics as a racial regime of modernity, the focus of Bradley’s Anteaesthetics is experiments in Black art which are not ‘worlding but an illimitable descent made to come before the world’. With a powerful introduction reflecting upon Nina Simone at the Montreal Jazz festival, and chapters which take us through 19th-century paintings, cinema, texts, video installations, and digital art, Anteaesthetics forces us to encounter the horror, beauty, and racially gendered dimensions of a negative inhabitation substantiated through the absolutely dispossessive field of worlding aesthetic refrains. Working against the grain of debate, aesthetics is not generatively enrolled for the modern subject possessed of ontological security to productively world itself in new ways. Rather, Anteaesthetics enables us to critically interrogate how investing in aesthetics requires working with the negative, taking an uncompromising stance towards aesthetics as a constitutive force of the ongoing violent legacies of modernity.

Optimizing of horizontal axis wind turbine blades using MATLAB-based blade element momentum theory with validation in QBlade and CFD software
Authors: Abbas Wissam K , Abbasalizadeh Majid , Khalilarya Shahram
Published: November 2024

This study presents the optimization of a small horizontal axis wind turbine blade at a low wind speed of 6 m/s. A MATLAB code employing Blade Element Momentum Theory (BEMT) was developed to optimize the chord length and twist angle. The optimized design was further analyzed and validated using QBlade software and ANSYS® 2022R1. The study considered two airfoils SG6041 and NACA4711 under Reynolds numbers of 1,000,000 and 100,000, respectively. The blades SG6041 and NACA4711 were divided into 10 and 20 segments for detailed analysis, resulting in power coefficients of 0.455 for SG6041 and 0.521 for NACA4711. The consistent results across MATLAB, QBlade, and ANSYS confirm the accuracy of the BEMT-based optimization process. The rotor achieved optimal performance at Tip speed ratios of 8.5 for SG6041 and 7.5 for NACA4711. Results demonstrated a high correlation between the power coefficients for QBlade and CFD simulations, with only a 1% variation for NACA4711 and 1.78% for SG6041. This study highlights a systematic approach for small wind turbine blade optimization, particularly at low wind speeds. Hence, it can be deemed that this approach is among the most crucial techniques for constructing and optimizing the blades and rotors of micro-wind turbines.

Published: November 2024

The process of desalination is crucial in mitigating the deficiency of drinkable water in the rural regions of Egypt. The implementation of hybrid energy systems, which integrate various renewable energy sources, presents a viable methodology for supplying potable water to islands and coastal areas that are devoid of adequate electrical infrastructure. This research conducts a comprehensive assessment of the technical configuration, sizing, and economic optimization of a reverse osmosis (RO) plant utilizing an off-grid hybrid energy system. The RO facility is designated for implementation at the NRC farm located in Nubaria, Egypt, with a projected freshwater production capacity of 65 m3/day. In this simulation, six distinct configurations of energy sources were analyzed to ascertain the most optimal arrangement for the specified site. The Homer software was employed to identify a system that is economically viable, environmentally sustainable, and socially responsible. The simulation was primarily concerned with the computation of the net present cost (NPC,) cost of energy (COE), and carbon dioxide emissions (CO2). Through the analysis, Configuration 3 was identified as the most efficient system setup, achieving a renewable fraction of 100 and comprises a 15 kW photovoltaic PV array, a 6 kW wind turbine, a 9 kW power converter, and a total nominal capacity of batteries 22 kWh. This particular configuration resulted in the lowest calculated COE $ 0.166/kWh and NPC $54,533.

Canada is experiencing an unprecedented primary care crisis, with 6.5 million Canadians reporting lacking a family physician, including 31% of the Quebec population. To address this problem, the province of Quebec implemented Primary Care Access Points (GAPs) to help unattached patients navigate and access primary care services while awaiting attachment. We aimed to examine the determinants associated with unattached patients receiving a medical appointment compared to another service through the GAP. Cross-sectional data (n = 13,291) from two GAPs were collected (June 2022 to March 2023). Multivariable logistic regression was carried out. Being younger, calling for an acute health problem, medication renewal or to have administrative documentation filled, having a physical or mental health problem, and using GAP A (compared to GAP B) were associated with an increased likelihood of receiving a medical appointment. This study is the first to document the characteristics of patients using the GAP and their needs.

Additionally, the research identified key elements necessary for the development of ally programs tailored for barbers in Black communities. Barbers emerged as crucial resources in the effort to combat violence against women in Black communities. Recognizing their specific interests and addressing their unique needs is essential for the success of programs harnessing their potential in this capacity.
Integral sliding-mode based interval type-2 fuzzy control for efficient networked nonlinear active suspension systems with input uncertainty
Authors: Xie Zhengchao , Lv Songming , Wong Pak Kin , Li Wenfeng , Zhao Jing
Published: November 2024

An event-triggered integral sliding mode control (ETISMC) approach for the networked nonlinear active suspension systems (ASSs) via interval type-2 (IT-2) T-S fuzzy logic is investigated in this paper. Firstly, in order to deal with the uncertainty in system masses, the nonlinearity of the suspension spring stiffness and damping coefficient, and the unknown actuator nonlinearity simultaneously, an ASSs model based on the IT-2 T-S fuzzy method is constructed. Secondly, a discrete event-triggered method is designed to process the sampled data and reduce the usage of vehicle CAN network communication resources. Thirdly, the H infinity robust method is used to handle the road disturbance and the sliding mode control (SMC) is adopted to deal with the actuator input uncertainty. To better integrate the SMC and event-triggered control (ETC), an ETISMC approach is explored for the ASSs. Finally, the numerical simulations and experiments are conducted to validate the effectiveness of the proposed strategy in this work.
Enhancing ride comfort and driving safety in urban autonomous buses: A data-driven hierarchical longitudinal motion planning using approximate and stochastic MPCs
Authors: Jo Ara , Yoon Youngmin
Published: November 2024

This paper presents an advanced hierarchical longitudinal motion planning strategy for autonomous buses (ABs), specifically designed to enhance ride comfort and ensure driving safety – key challenges in contemporary autonomous vehicle technologies. ABs typically face limitations due to a narrower perception range and heterogeneous motion profiles compared to human drivers. To tackle these issues, our study employs a dual-phase motion planning framework utilizing both approximate and stochastic Model Predictive Controls (MPCs). In the long time-horizon planning phase, we aim to enhance ride comfort by optimizing a reference motion profile that covers the full perception range of the ABs. This optimization is facilitated by leveraging deep neural networks to approximate the MPC policy, ensuring efficient real-time computational performance. The short time-horizon planning phase focuses on driving safety by determining optimal control inputs, considering vehicle dynamics, and integrating safety-related chance constraints with stochastic MPC. Additionally, this phase fine-tunes the weights in the MPC’s objective function based on risk indices derived from human driving data, balancing the priorities of safety in hazardous situations and maintaining ride comfort. Our hierarchical motion planning strategy ensures both consistent ride comfort and safety in critical scenarios. Through comprehensive evaluations using computer simulations and vehicle tests in actual urban bus-only lanes, the proposed method has proven to significantly enhance ride comfort while maintaining driving safety. This approach contributes to the ongoing improvement of the operational quality of ABs, supporting public transportation goals and meeting passenger expectations effectively.
Lane change path planning using sweeping region for full-sized autonomous driving bus in urban environment
Authors: Yoon Youngmin , Lee Jaewan
Published: November 2024

This paper presents a path planning method for the lane change maneuver of a full-sized autonomous driving bus in urban environment. A sampling method is incorporated for lane change path planning. Path candidates for lane changes are generated using the pattern of a quintic polynomial function. For optimal path selection among the candidates, a cost function and constraints are designed and applied, considering ride quality, lane change efficiency, and safety. Safety conditions account for lane departure and collision with obstacles. Considering large vehicles such as buses, the region swept by the vehicle body is derived by exploiting the geometrical relationship of the control point and corners, assuming that the control point follows the investigated path candidate. The sweeping region is utilized for accurate and efficient evaluation of the safety condition of the path candidate. Subsequently, longitudinal motion is planned based on Model Predictive Control (MPC) to maintain adequate clearance with surrounding vehicles and follow the desired speed. The proposed algorithm has been evaluated based on closed-loop simulations and vehicle-in-the-loop tests. The test results show that the proposed algorithm plans a safe lane change path, ensuring the vehicle body remains within the safe region. Additionally, the proposed algorithm is shown to enhance real-time performance.

Authors: Zhang Xiaofeng , Li Hao , Song Jian , Zhou Dehua
Published: November 2024

An energy-harvesting suspension can improve the energy efficiency of vehicle. By introducing a lower-mobility parallel mechanism as motion transfer in the energy-harvesting suspension, the stiffness of the system is significantly improved. However, the overlage equivalent of inertial mass make the system is difficult to control and imped the development of this kind of suspension. To solve the problem, an equivalent linearization model to calculate the nonlinear inertial mass of low-DOF (Degree Of Freedom) parallel mechanism actuator is studied firstly. Furthermore, a 2-DOF 1/4 suspension system dynamic model that includes inertial mass is proposed to analyze the vehicle acceleration, dynamic tire load, and dynamic stroke. On this basis, the linear-quadratic Gaussian (LQG) controller is adopted to compensate the inertial mass of the suspension to improve the system performance. Results show that the proposed model accurately reflects the characteristics of the suspension inertial mass, the root-mean-square (RMS) value of the vehicle body acceleration and suspension dynamic stroke through compensation controller is reduced by 33.4% and 30.89%, respectively. Moreover, the RMS of the dynamic tire load is reduced by 3.06%, and the system stability is improved significantly.

Alveolar Bone Graft Supplemented With Stromal Vascular Fraction in Patients With Permanent Dentition: A Randomized Study
Authors: Kurimori Kleber Tetsuo , Bastos Endrigo Oliveira , Camara Paulo Roberto Pelucio , Mascarenhas Dias Beatriz , Uyeda Giovanna Layse , Alonso Nivaldo
Published: November 2024

Objective

To evaluate bone development in patients with alveolar clefts and permanent dentition treated with alveolar bone graft supplemented with stromal vascular fraction (SVF).

Design

Clinical, prospective, randomized.

Location

Single tertiary care institution.

Patients

Eighteen participants with unilateral alveolar cleft and permanent dentition were included. Patients with other comorbidities were excluded.

Intervention

The control group underwent alveolar bone grafting (ABG) using iliac crest bone, while the experimental group underwent the same treatment, supplemented with SVF. Adipose tissue was collected by abdominal liposuction, and the SVF was processed using mechanical methods (decantation, microfragmentation, and filtration).

Main Outcome Measurement

Bone formation and bone graft integration rate in alveolar cleft at 6 months postsurgery using 3-dimensional tomographic methods and density measurements.

Results

The amount of bone graft correlated with an improvement in the relationship between the cleft and noncleft sides (R = 0.78, P < .001) and an improvement in alveolar cleft density (R = 0.69, P = .005), but did not correlate with the graft integration rate. The experimental group showed larger cleft sizes (0.83 × 1.74 cm3, P = .021) and older patients (17.35 × 27.6 years, P = .002), and did not differ in terms of bone development variables when compared to the control group.

Conclusion

ABG supplemented with SVF showed statistically similar bone development results, but with a better trend than conventional ABG. Additionally, the studied groups had asymmetric pre-existing characteristics, with greater severity in the experimental group. A larger study will be necessary to mitigate preoperative characteristic differences and to more accurately compare the results between the methods.

A Rare Presentation of IgG4-Related Disease with Gastric Outlet Obstruction and Lymphadenopathy: A Case Report
Authors: Alsaifi Masoud , Al Sawafi Yaqoob , Al Julandani Nabila
Published: November 2024

Background. IgG4-related disease (IgG4-RD) is a systemic immune-mediated condition characterized by fibro-inflammatory infiltration. It is a rare disease that can affect any organ, with the involvement of the stomach being particularly uncommon. The clinical manifestations of IgG4-RD are highly variable depending on the type and number of organs involved and mirror the symptoms of other conditions. Case presentation. We report a 61-year-old man who presented with symptoms of gastric outlet obstruction and was subsequently diagnosed with IgG4-RD. The patient experienced recurrent vomiting, early satiety, and substantial weight loss. Imaging studies revealed luminal narrowing in the pyloric region, prompting further endoscopic evaluation. Initial endoscopic biopsies were nondiagnostic. Because the patient's clinical symptoms and previous investigations were highly indicative of malignancy, he underwent distal gastrectomy with Roux en Y anastomosis. However, final histopathology revealed lymphoplasmacytic infiltration and dense fibrosis, confirming the diagnosis of IgG4-RD; no malignant cells were noted. The surgery resulted in symptom improvement. Conclusion. This presentation highlights the diagnostic challenges of IgG4-RD with gastric outlet obstruction, emphasizing the significance of a multidisciplinary approach involving clinical, radiological, and histopathological assessments to achieve an accurate diagnosis and develop tailored management strategies.
Change in hair texture with the use of pomalidomide for multiple myeloma: From straight to curly phenotype
Authors: Zahid Annam , Dasanu Constantin A.
Published: November 2024

Introduction

Pomalidomide is used for treating multiple myeloma in patients who have relapsed after prior treatment with lenalidomide and a proteasome inhibitor. Common side effects include mild cytopenias, and deep vein thrombosis. While papulo-erythematous rash has been described, hair effects are rare with this class of agents.

Case Report

We describe a 56-year-old man who was diagnosed with multiple myeloma type IgD lambda six years prior. He responded very well to initial treatment with bortezomib-lenalidomide-dexamethasone. After two years, he had a recurrence that was treated with daratumumab-pomalidomide-dexamethasone, and he entered a stringent complete response (CR) within six months. Daratumumab was discontinued after twelve months, and he subsequently remained on maintenance therapy with pomalidomide. Three months into the maintenance regimen, he noticed a change in hair texture to curly, which continued to progress. Causality assessment linked this change to pomalidomide use via the Naranjo nomogram questionnaire, by scoring 5.

Management and Outcome

Pomalidomide maintenance therapy was continued without any dose alterations given the excellent clinical outcome. A year later, multiple myeloma remains in stringent complete response. The patient remains with a curly hair phenotype, having fully embraced his new physical appearance.

Discussion/Conclusion

We report herein a unique hair texture alteration linked with pomalidomide use, not previously documented in literature. The observed hair texture change, from straight to curly, requires further investigation. Future studies may offer more insights into the mechanisms underlying this rare, yet intriguing side effect.
Temozolomide overcoming resistance to immune checkpoint inhibitors in relapsed/refractory metastatic melanoma? Insights from a single center series
Authors: Dasanu Constantin A , Plaxe Steven C
Published: November 2024

There is a need to develop more effective salvage therapies for patients with relapsed melanoma of the skin. Research has shown that chemotherapy-induced cancer cell death may increase immunogenic antigen exposure, or upregulation of co-inhibitory ligands such as PD-L1, thereby augmenting immune checkpoint inhibitor (ICI) efficacy. In addition, chemotherapy preconditioning may lead to depletion of Tregs, known to suppress immune anti-melanoma responses. As a result, regimens including both chemotherapy and ICI constructs are currently successfully employed in the 1st line therapy of many solid tumors. We report a series of three patients with metastatic melanoma, refractory to ICI treatment, who responded to salvage therapy with temozolomide (TMZ) in combination with PD-1 inhibitors, with or without CTLA-4 inhibitors. The responses were durable, each lasting more than 12 months. In two patients, complete responses are ongoing at 13 and 15 months, respectively. Randomized clinical trials with TMZ plus ICIs for patients with relapsed or refractory malignant melanoma seem warranted.

Introduction

Rock climbing has recently gained popularity, particularly among females. There are no current studies evaluating pelvic floor dysfunction among female climbers. This cross-sectional study seeks to investigate the prevalence of incontinence and pelvic floor disorders among female rock climbers in the United States.

Methods

This study utilized an online survey distributed via social media platforms to assess the prevalence of pelvic floor disorders. Participants were queried about demographic information, climbing habits, pregnancy history, and pelvic floor symptoms. Data analysis involved descriptive statistics and inferential analysis where applicable.

Results

A total of 343 participants completed the study, with a median age of 34 years, lean body mass, and the majority identifying as White or Caucasian. The most common pelvic floor disorder was overactive bladder ( n = 314, 91.5%), and the least common was pelvic organ prolapse ( n = 6, 1.7%). Rope climbers were significantly more bothered by pelvic organ prolapse and anal incontinence symptoms than boulderers (4, p < .01 and 1.44, p < .01, respectively). Parous climbers reported significantly higher bothersome symptoms of OAB and SUI (1.43, p = .01 and 2.71, p < .01, respectively) than their nulliparous counterparts.

Conclusions

Although rock climbing represents a relatively low-impact sport and our sample was largely comprised of young, healthy, nulliparous women, female rock climbers demonstrated higher rates of pelvic floor disorders than a normative population, with rope climbers at higher risk than boulderers. Clinicians should be aware of the need for more frequent pelvic floor disorder screening in active women.
A Rare Case of an Infant With TFE3 Mutation Presenting With Direct Hyperbilirubinemia and Hepatomegaly

Translocations within the TFE gene resulting in oncogenic fusion proteins have been associated with multiple neoplasms. De novo mutations in the X-linked gene TFE3 in exons 3 and 4 are considered to contribute to lysosomal storage disorder-like features. However, the histologic findings within the livers of patients with TFE3 mutations are not well characterized. The authors report a case of a 12 day old term male who was admitted to the pediatric intensive care unit and went on to develop worsening direct hyperbilirubinemia and hepatomegaly. Due to the constellation of clinical findings, whole genome sequencing was performed and a rare de novo hemizygous mutation was identified in the TFE3 gene (c.560C > T; p.Thr187Met) which was thought to be likely pathogenic. The patient subsequently had 2 liver biopsies performed, both with similar histologic findings. The liver was found to have a giant cell hepatitis pattern of injury with severe cholestasis and extensive pseudorosette formation. Additional studies are needed to understand the histologic changes which could be associated with mutations in the TFE3 gene. The impact of a TFE3 mutation on the liver represents an area where further study is necessary to provide prognostic and therapeutic guidance for future patients.
Family Tourist Emotional Experience: Emotion-Generative and Regulatory Process

Family tourism has received much scholarly attention, but few studies have examined family tourists’ experience by viewing them as active agents that generate and regulate emotions. This study aims to disclose family tourists’ dynamic emotional experiences through probing into their emotion generative and regulatory process. An extended Chinese family taking a 6-day overseas trip was recruited and each member was interviewed multiple times throughout the pre-, during- (assisted by participatory observation and psychophysiological data), and post-trip phrases. The family tourists reported 64 emotional episodes, 32 discrete emotions, and 13 emotion regulation strategies. Their emotion-generation and regulation were revealed as an interdependent and cyclical cognitive appraisal process that occurs in complex social settings. The proposed psychological mechanism model contributes to tourism and psychological literature by highlighting the dynamic and social nature of family tourists’ emotions, and the role of memory in their emotion dynamics. Future research directions on family tourists’ emotion regulation are suggested.

Auxetic metamaterials, known for their unusual properties, are being explored as cores for sandwich structures to improve impact resistance. This study investigated the low-velocity impact response of sandwich panels with various core designs using finite element method (FEM) and experiments on 3D-printed specimens. These cores include pure honeycomb, pure auxetic, and gradient variations with controlled gradients of Poisson’s ratio, transitioning from negative to positive (NTP), positive to negative (PTN), negative-to-positive-to-negative (NTPTN), and positive-to-negative-to-positive (PTNTP). These gradients were achieved by adjusting the unit cell angle within the core. Under quasi-static indentation, the gradient PTN design improved energy absorption by 26% compared to the honeycomb structure, while the gradient NTP structure showed a 9% improvement over the auxetic core. As for the impact tests, the gradient NTP and PTN structures significantly enhanced the indentation resistance of auxetic and honeycomb structures by 21.3% and 6.5%, respectively. Interestingly, while the optimal core for peak energy absorption varied with impact velocity, gradient structures generally provided superior energy absorption, particularly at lower velocities. FEM results at initial impact velocities of 10, 15, 20 m/s confirmed that structures having negative Poisson’s ratio at their top layer exhibited the lowest penetration depth. Additionally, gradient structures, particularly NTP and NTPTN, demonstrated superior energy absorption capability compared to purely auxetic or honeycomb structures, especially at lower velocities. The study highlights the benefits of utilizing gradient auxetic metamaterial cores in high-performance sandwich structures for impact resistance applications. These structures showed minimal localized damage, reduced densification risk due to uniform crushing, and lower penetration depth.
