Abstract
Dynamic processes of the oceanic crust of seamounts trapped in continental sutures are poorly understood. The discovery and analysis of seamount sequences in the Yarlung Zangbo suture zone allowed us to detect vertical lithospheric movements of the eastern Neo-Tethys Ocean. In this study, we used petrological, geochemical, facies, paleontological, and stratigraphic methods to study composite blocks of mafic and sedimentary rocks in the Zhongba area of Xizang, China. Radiolarian fossils indicate an (early) Early Cretaceous age. Petrofacies and geochemistry show that most basalts occur as pillow lava and are enriched in light rare earth elements and high field strength elements, which suggests an oceanic-island basalt tectonic setting. Sedimentary lithofacies are grouped into breccias, shales, cherts, and limestones (ooid and cortoid grainstone microfacies). Three types of contact between basaltic basements and caps were identified as regular, talus, and erosive. These results demonstrate that two more superposed seamounts exist in the western Yarlung Zangbo suture zone than was known previously, and they comprise at least eight seamount sequences of basalts to sediments. Cap lithofacies and seamount textures illustrate that overall, the Zhongba paleo-seamounts record multiple cycles of abrupt deepening to shallowing, with water depth variations of ~3000 m to ~5 m due to multiple episodes of quick subsidence and uplift of seamounts (lithospheric “ups and downs”). The model of oceanic bypass recurrence and plume rejuvenation is hypothesized to explain the dynamic subsidence and uplift. While plume activities produced the mafic basement and considerable buoyancy-related lift, oceanic crust bypassed drift, created distance from the plumes, and led to cooling, loss of buoyancy, and rapid subsidence. This model provides a new approach to interpret the evolution of oceanic crusts that have disappeared.
Colloidal Quantum Dots: 4. Colloidal Quantum Dots and Basic Photoluminescence Laws
Authors: Razumov V. F. , Tovstun S. A. 
Published: August 2024

Abstract
A brief review of the well-known laws and rules of photoluminescence is given, and it is shown that these laws usually do not hold for CQD solutions. It has been shown that this is due to a special mechanism for the formation of the luminescent properties of CQDs. The derivation of a new universal law of photoluminescence, applicable to any type of luminophores, which has recently been substantiated theoretically and verified experimentally using the example of CQDs, is presented.

ObjectiveTo provide contemporary data on cancer mortality rates within the context of incidence in the population with intellectual disabilities.MethodsScotland’s 2011 Census was used to identify adults with intellectual disabilities and controls with records linked to the Scottish Cancer Registry and death certificate data (March 2011–December 2019). The control cohort without intellectual disabilities and/or autism were used for indirect standardisation and calculation of crude incident rates/crude mortality rates, and age–sex standardised incident rate ratios/standardised mortality ratios (SIR/SMR), with 95% CIs.ResultsAdults with intellectual disabilities were most likely diagnosed cancers of digestive, specifically colorectal (14.2%), lung (9.3%), breast (female 22.9%), body of the uterus (female 9.3%) and male genital organs (male 17.6%). Higher incident cancers included metastatic cancer of unknown primary origin (female SIR=1.70, male SIR=2.08), body of uterus (female SIR=1.63), ovarian (female SIR=1.59), kidney (female SIR=1.85) and testicular (male SIR=2.49). SMRs were higher, regardless of a higher, similar or lower incidence (female SMR=1.34, male SMR=1.07). Excess mortality risk was found for colorectal (total SMR=1.54, male SMR=1.59), kidney (total SMR=2.01 u, female SMR=2.85 u), female genital organs (SMR=2.34 (ovarian SMR=2.86 u, body of uterus SMR=2.11), breast (female SMR=1.58) and metastatic cancer of unknown primary origin (female SMR=2.50 u, male SMR=2.84).ConclusionsAdults with intellectual disabilities were more likely to die of cancer than the general population. Reasons for this may include later presentation/diagnosis (so poorer outcomes), poorer treatment/compliance or both. Accessible public health approaches are important for people with intellectual disabilities, and healthcare professionals need to be aware of the different cancer experiences faced by this population.

ObjectivesThis study aims to determine the factors influencing eye care service utilisation and compliance with spectacles wear among school students.DesignMixed-methods study.Setting27 community schools from 6 districts of Bagmati province of Nepal.ParticipantsAdolescents with mild vision impairment who were screened at schools by their trained peers for visual acuity measurement and subsequently received subsidised spectacles for refractive error correction. For the quantitative study, 317 students from 21 schools completed the survey. For qualitative study, 62 students from 6 schools participated in 6 focus group discussions.Primary outcome measuresUtilisation of eye care services and compliance with spectacles wear.ResultsAmong 317 students, 53.31% were aged 15–19, and 35.96% were male. More than half (52.68%, n=167) did not use eye health services. Among students who did not go, 51.50% reported eye health facilities being far away. Thematic analysis showed that distance, COVID-19 and awareness were influential in the utilisation of eye care. The multivariate analysis showed urban residents were likelier (adjusted OR (AOR) 4.347, 95% CI 2.399 to 7.877, p<0.001) to use eye care services. During an unannounced visit to schools after 3–4 months of spectacles distribution, 188 (59.31%) students were wearing spectacles. 20.16% of students not wearing spectacles reported they did not feel the need. Thematic analysis showed the influence of family and peers, affordability, aesthetic appearance, comfortability and symptomatic relief in spectacles compliance. The multivariate analysis showed that urban residents (AOR 2.552, 95% CI 1.469 to 4.433, p<0.001), older adolescents (AOR 1.758, 95% CI 1.086 to 2.848, p=0.022), mothers with paid jobs (AOR 2.440, 95% CI 1.162 to 5.125, p=0.018) and students visiting eye care centres (AOR 1.662, 95% CI 1.006 to 2.746, p=0.047) were more likely to be compliant with spectacles wear.ConclusionsThere are multiple barriers for students to use eye care services and stay compliant with spectacles wear. Eye health programmes should include eye health promotion and be accessible, affordable and equitable.

Published: August 2024

AbstractThis paper investigates the axial gravitational perturbations originating from spherically symmetric black holes in f(R) gravity, along with the optical appearance of such a black hole. The aim is to search for evidence of the existence of these black holes in astrophysical observations and thereby test the correctness of the f(R) theory. In literature Kalita and Mukhopadhyay (Eur Phys J C 79:877, 2019), the spherically symmetric black hole metric in f(R) gravity is obtained. By comparing it with the metric for spherically symmetric black holes in general relativity, we find that the modification of gravity due to f(R) can be described in this black hole spacetime using a parameter $$C_f$$

Anisotropic compact stellar model: a vanishing complexity approach
Authors: Das Shyam , Sarkar Nayan , Das Amit , Pal Shyamal Kumar 
Published: August 2024

AbstractIn this article, we develop a new class of solutions that describe stellar structures of recently observed pulsars. We adopt the condition of the vanishing complexity proposed by Herrera (Phys Rev D 97:044010, 2018) and an appropriate metric potential for generating the solutions. The solutions which are obtained from the complexity-free conditions, are physically well-behaved and satisfy all the rigorous conditions to describe static and spherically symmetric realistic compact objects. The features of observed anisotropic compact stars including Vela X-1, LMC X-4, Cen X-3, and EXO 1785-248 are validated with our model. It is further shown that the solutions supporting matter configurations are physically plausible, stable with positive anisotropy, and in an equilibrium state as verified by investigating the generalized TOV equation in the case of our model.

A biodiversidade é essencial para o equilíbrio e correto funcionamento dos ecossistemas do planeta. Mas, devido aos avanços da agricultura, o desflorestamento, o desenvolvimento urbano e demais atividades antrópicas, a biodiversidade tem sofrido severamente e está ameaçada. Nesse contexto, inclui-se as populações de polinizadores naturais, por não encontrarem mais recursos suficientes para se alimentar e fazer seus ninhos ー principalmente as abelhas, que possuem um papel crucial para mitigar os impactos ao planeta, pois são fundamentais à reprodução de uma ampla variedade de plantas. A perda de uma espécie desse inseto é capaz de reduzir ou mesmo extinguir espécies vegetais, de modo a alterar o meio ambiente e principalmente a produção de alimentos. Nesse contexto, o conhecimento sobre as abelhas bem como a importância delas ao meio ambiente e à nossa alimentação é essencial para agirmos em sua proteção. Elaborado por uma equipe interdisciplinar, o livro “Abelhas Sem Ferrão na Horta da Faculdade de Saúde Pública” é resultado do desejo do Projeto Horta da FSP-USP de disseminar a importância das Abelhas Sem Ferrão (ASF) para o equilíbrio e correto funcionamento dos ecossistemas do planeta e para a Segurança Alimentar e Nutricional. Esta obra está organizada em treze partes. Primeiro são apresentadas informações gerais sobre a biodiversidade e polinização. Em seguida, adentra-se no mundo das abelhas, abordando sobre o que são esses seres, como e onde vivem, quais suas contribuições para nós humanos e as espécies de ASF presentes na Horta da FSP-USP. Por fim, são trazidas plantas cultivadas na Horta, polinizadas pelas ASF, bem como os cuidados a serem tomados na utilização de plantas medicinais e quais as formas de preparo de chás.
Influence of the Atlantic and Pacific Multidecadal Variability on Arctic Sea Ice in Pacemaker Simulations during 1920–2013

Published: August 2024

Abstract
The Atlantic multidecadal variability (AMV) and Pacific multidecadal variability (PMV) can influence Arctic sea ice and modulate its trend, but to what extent the AMV and PMV can affect Arctic sea ice and which processes are dominant are not well understood. Here, we analyze the Community Earth System Model, version 1, idealized and time-varying pacemaker ensemble simulations to investigate these issues. These experiments show that the sea ice concentration varies mainly over the marginal Arctic Ocean, while the sea ice thickness variations occur over the entire Arctic Ocean. The internal components of AMV and PMV can enhance or weaken the decadal sea ice loss rates over the marginal Arctic Ocean by more than 50%. The AMV- or PMV-induced anomalous atmospheric energy transport and downward longwave radiation related to low clouds (thermodynamical processes) and sea ice motion (dynamical processes) contribute to the Arctic surface air temperature and sea ice concentration and thickness changes. Anomalous oceanic heat flux is mainly a response to rather than a cause of sea ice variations. The dynamic processes contribute to the winter Arctic sea ice variations as much as the thermodynamic processes, but they contribute less (more) to the summer Arctic sea ice variability than the thermodynamic processes over the marginal Arctic Ocean (parts of the central Arctic Ocean). Sea ice loss enhances air–sea heat fluxes, which cause oceanic heat convergence and warm near-surface air and the lower troposphere, which in turn melt more sea ice.
Tailoring the vibration characteristics of carbon fiber-reinforced polylactic acid in fused filament fabrication process

Published: August 2024

The Fused Filament Fabrication (FFF) process has gained significant attention for its ability to manufacture parts using advanced polymeric materials, such as carbon fiber-reinforced polylactic acid (CF-PLA). By adjusting the printing process parameters of the CF-PLA, the optimized mechanical properties can be achieved with less chances of flaws. Structural integrity of the components plays an important role in analyzing the durability of the product which can be analyzed using modal analysis. This research study focuses on analyzing the effect of process parameters on the vibration damping characteristics of CF-PLA components produced by the FFF process. The Taguchi method is used to model the relationship between process parameters and vibration performance metrics. Based on the vibration study, the optimal process parameters were determined as 60% infill density, 0.08 mm slice thickness, and hexagonal pattern. This study shows that the natural frequency and damping increases with increase in infill percent but decreases with increase in slice thickness. The closely aligned values between the predicted and experimental results suggest that the developed model is effective in predicting the vibration characteristics of CF-PLA composites. By accurately adjusting the process parameters, the study’s findings—such as frequencies and damping ratio—provide manufacturers with important and dependable CF-PLA Fused Deposition Modeling components.

Purpose To investigate whether changes in volunteering from adolescence to young adulthood are associated with subsequent health and well-being outcomes in adulthood. Design Longitudinal cohort study. Setting National Longitudinal Study of Adolescent to Adult Health. Subjects U.S. adults from Wave IV (2008/2009; N = 12,234) and Wave V (2016-2018; N = 9,971). Measures Any volunteering and nine types of volunteering (independent variables) and 41 health and well-being outcomes (dependent variables) using an outcome-wide approach with multiple linear-, logistic-, and generalized linear regressions. Results Volunteering in young adulthood was associated with better health behaviors (e.g., 34% decreased risk of binge drinking, 95% CI [0.54, 0.81]) and improved psychosocial and civic outcomes (e.g., lower depressive symptoms (β = −0.08, 95% CI [−0.14, −0.02]) in adulthood. Volunteering showed little evidence of associations with other health and well-being outcomes (e.g., loneliness, (β = −0.04, 95% CI [−0.09, 0.01])). Assessing volunteering by organization types showed a range of positive and negative outcomes. For example, volunteering in hospitals/nursing homes was associated with a 36% increased risk of high cholesterol (95% CI [1.06, 1.73]) and volunteering with political clubs was associated with a 52% increased risk of an anxiety diagnosis (95% CI [1.13, 2.05]). Conclusion Our findings suggest more work is needed to determine the conditions under which volunteering is health promoting and to minimize potential adverse effects associated with some types of volunteering.
Long-term remission with temozolomide for AIDS-related primary central nervous system lymphoma

Published: August 2024

Primary Central Nervous System Lymphoma (PCNSL) is an aggressive brain tumour with a median survival rarely exceeding 3 months without treatment when seen in association with advanced HIV. High dose methotrexate (HD-MTX) in association with combination antiretroviral therapy (cART) is the recommended chemotherapy. However, HD-MTX may be not feasible due to poor performance status and concerns about toxicity. The 2023 guidelines from the European Association of Neuro-Oncology recommend that for people living with HIV (PLWH) presenting with PCNSL who have morbidities and/or poor functional status precluding the safe use of HD-MTX, other agents with a more favorable toxicity profile such as temozolomide might be considered. However, reports of temozolomide use for PLWH presenting PCNSL are exceedingly rare and this recommendation is extrapolated from its use in immunocompetent patients. We report here an elderly man living with HIV, with PCNSL and poor performance status who achieved long lasting remission with temozolomide plus cART. Our case illustrates the potential effectiveness of temozolomide in association with cART as first line treatment for PCNSL in a patient with poor functional status.

Published: August 2024

The use of space technology and small space loads is increasingly common. To address this, a mechanism for isolation vibration in small optical load has been proposed. The mechanism includes a coarse and fine stage parallel pointing platform (CFPP). This paper investigates an active vibration isolation scheme for the novel pointing stabilization mechanism. The kinetic energy minimization principle is derived from the analysis of its working mechanism and dynamic feedforward characteristics. This principle is confirmed by the feedforward of the indeterminate degrees of freedom of the under-constrained mechanism. A hybrid control scheme of feedback and feedforward is developed based on the H∞ algorithm and the optimal feedforward control algorithm. Simulation and experimentation have proven that the vibration isolation efficiency of more than 20 dB can be achieved in all three axis rotation directions. This meets the precision pointing requirements of small optical load effectively.
Trastuzumab-induced optic neuritis: “blindness” side effect
Authors: Önder Tuğba , Karaçin Cengiz 
Published: August 2024

Introduction Trastuzumab improved the prognosis of patients with human epidermal growth factor receptor 2 (HER2)+ breast cancer (BC). Here, we present a patient who developed acute vision loss due to optic atrophy in both eyes after trastuzumab. Case report A 60-year-old female patient was diagnosed with locally advanced HER2+ BC in January 2021. After four cycles of neoadjuvant anthracycline-based chemotherapy followed by four cycles of docetaxel, trastuzumab, and pertuzumab combined treatment, the patient underwent a right modified radical mastectomy. Three days after the end of the second cycle of adjuvant trastuzumab, she presented with acute vision loss. The patient's visual acuity was 90% in the right eye and 60% in the left eye. The left eye had optic nerve edema and spindle hemorrhages. First, on suspicion of optic neuritis, the patient was given a 1 gram/day pulse steroid for three days. However, optic neuritis was not considered during the follow-up. Metastasis was considered at the exit of the left optic nerve. Trastuzumab was started by making a mutual decision with the patient. Six days after the sixth dose of adjuvant trastuzumab, she presented with almost complete vision loss. Management and outcome The patient was diagnosed with optic neuritis, and a pulse steroid was administered. Trastuzumab was permanently discontinued. However, the patient's visual acuity in both eyes remained at 5–10%. Discussion Vision loss due to optic neuritis is a devastating side effect. Understanding that trastuzumab-induced optic neuritis may develop will help clinicians detect side effects early and manage them more effectively.
