Исследована депрессия талька при его мономинеральной флотации с применением анионоактивных полимерных реагентов: карбоксиметилированного крахмала (КМК) и целлюлозы (КМЦ), сульфонатов, а также соединения с многозарядными катионами металлов. Полистиролсульфонат натрия с молекулярной массой 106 кг/кмоль по эффективности депрессии талька сильнее сульфонатов с меньшей молекулярной массой, но уступает КМЦ и КМК. Катионы Mg и Al при концентрации 2.5 мг/л повышают эффективность депрессии талька с применением полистиролсульфоната натрия на ~ 4 %. Дальнейшее увеличение концентрации катионов металлов снижает эффективность депрессии талька. Добавление полистиролсульфоната натрия с концентрацией до 250 мг/л изменяет электрокинетический потенциал талька с - 20 до - 32 мВ. По сравнению с КМК и КМЦ полимерные сульфонаты обладают меньшим адсорбционным сродством к тальку. Предложено два варианта механизма взаимодействия полимерных сульфонатов с базальной поверхностью талька: в отсутствии многозарядных катионов металлов и при предварительном добавлении указанных катионов.
The authors investigate depression of talc in its monomineral flotation with polymeric anion active reagents: carboxy methyl starch and carboxy methyl cellulose (CMS and CMC, respectively), sulfonates, as well as compounds with polyvalent cations of metals. Sodium polystyrene sulfonate with molecular mass of 106 kg/kmol is more effective in talc depression than sulfonates of smaller molecular mass, but gives way to CMS and CMC. Cations of Mg and Al at concentration of 2.5 mg/l increase efficiency of talc depression with sodium polystyrene sulfonate by 4%. The further rise in concentration of cations of metals weakens depression of talc. Addition of sodium polystyrene sulfonate up to concentration of 250 mg/l changes electrokinetic potential of talc from - 20 to - 32 mV. As compared with CMS and CMC, polymeric sulfonates have lesser adsorption affinity to talc. The authors propose two alternative mechanisms of interaction between polymeric sulfonates and basal surface of talc: without polyvalent cations of metals and with preliminary addition of these cations.

Выполнены исследования электроимпульсной дезинтеграции сподуменсодержащих пегматитов. Установлено, что обработка импульсными электрическими разрядами обеспечивает частичное раскрытие мономинеральной части сподумена, при этом наилучшее выделение кристаллов сподумена в срастаниях и без таковых происходит при измельчении исходной породы до крупности от 1 до 4 мм. Сами кристаллы сподумена практически не разрушаются, как при механической обработке, и представляют собой цельные фрагменты. Последующее гравитационное разделение позволит получить сподуменовый концентрат для дальнейшего извлечения лития.
Electric disintegration of spodumene pegmatites is investigated. It is found that treatment with electric pulses ensures partial dissociation of monomineral spodumene, and the best extraction of spodumene crystals, either with or without concretions, takes place when initial rock is ground to a size of 1 to 4 mm. The crystals of spodumene remain unbroken, as in mechanical treatment, and represent whole pieces. The gravity separation later on allows production of spodumene concentrate for the subsequent lithium extraction.
Análisis cualitativo para la creación de escenarios sobre la relación entre la minera Las Bambas y las comunidades locales
Authors: Vargas Mayer Luis Enrique 
Published: February 2025

This research work is focused on problems of social interaction between a large-scale mining company, “Las Bambas” and its surrounding populations; Specifically, it focuses on looking for future scenarios of this social interaction that serve as an exploratory basis for future research. To this end, this work focuses on the qualitative analysis of journalistic media of various political tendencies and seeks to project future scenarios based on three variables: effects of social responsibility, social conflict and the trinomial “economy – power – inefficiency of the apparatus state"; These variables are understood to be of great importance for social transformation and are analyzed from the theoretical basis to integrating it with reality based on content analysis. The result allows us to deliver 4 scenarios: trend, utopian, normative and contrast; finding that, in a trend scenario, which is projected from the current context and without finding important adjustments to the current reality, results in a scenario where populations persist in achieving shareholding, economic dependence, situations of social conflict and increase of radical ideas.

OBJECTIVES
To determine parent perspectives on (1) the connection between voting and child health and (2) the best ways for clinicians to promote voter engagement among patients and their families.

METHODS
Qualitative study with semistructured interviews. Parents or guardians of all patients of academic pediatric primary care offices at a large, urban children’s hospital in the Midwestern United States were invited to participate by email. Participants completed demographic and voting habits surveys. Trained coders independently analyzed transcripts using iterative, thematic, inductive open coding.

RESULTS
We conducted 22 interviews. Most participants were female (91%), Black (55%), and non-Hispanic (95%). Participants represented a variety of education levels, political perspectives, and degrees of civic participation. Themes on the connection between voting and child health included the following: (1) voting helps “make your community a better place” for children now and in the future; (2) voting impacts funding for services that affect child health; and (3) voting influences our social environment, which in turn impacts child health. Themes on recommendations for health care–based voter engagement included the following: (4) consider context about voting messaging (eg, provide context about connection with health); (5) provide a variety of communication media options for delivering voting information; and (6) include a variety of health care staff in delivering voting messages.

CONCLUSIONS
In this qualitative study, we captured parent perspectives on the connection between voting and child health and desired methods for health care–based voter engagement. Our findings can inform future hypotheses for testing the mechanisms underlying established connections between voting and child health outcomes.

Published: February 2025

An atraumatic subdural hematoma (SDH) in a pediatric patient is a rare clinical entity. Although the United States Food and Drug Administration lists SDH as a possible adverse effect of adalimumab therapy for rheumatoid arthritis, the literature lacks reports of SDH in patients on adalimumab. A boy aged 16 years old with a history of ulcerative colitis on adalimumab presented with headache and a right pronator drift. Imaging demonstrated a 2.4-cm SDH on the left with 1.4 cm of midline shift. The patient underwent craniotomy and SDH evacuation, which revealed chronic SDH fluid and subdural membranes. Imaging and culture results did not suggest any other etiology (trauma, vascular malformations, infectious etiologies, or posterior reversible encephalopathy syndrome). The patient was transitioned from adalimumab therapy to ustekinumab therapy and did well without any recurrence.

Peripheral compound odontoma: A rare case report
Authors: Peranovic V , Bunn BK , Gwengu P 
Published: February 2025

Odontomas are currently classified as benign mixed epithelial/mesenchymal odontogenic neoplasms which are located within the tooth-bearing regions of the jaws. Despite being considered neoplasms, the clinical characteristics of these lesions are much the same as hamartomatous lesions. Peripheral odontomas are rare entities that are located entirely within the adjacent soft tissue of the mucosa and/or gingiva. Apart from location, peripheral odontomas are morphologically, radiologically and pathologically indistinguishable from their intraosseous counterparts.

Background. Patients with germ cell tumors (GCTs) and poor-prognosis demonstrate unsatisfactory oncological outcomes, with a one-year progression-free survival (PFS) rate of approximately 50%. We hypothesized that switching the chemotherapy regimen to TIP (paclitaxel, ifosfamide (mesna), cisplatin) in cases of unfavorable decline of serum tumor markers (STMs) after the first cycle of BEP (bleomycin, etoposide, cisplatin) could improve treatment outcomes in this subgroup of patients.Materials and Methods. A multicenter, prospective, non-randomized phase II study included patients with nonseminomatous GCTs and poor-prognosis according to IGCCCG. All patients received the first cycle of chemotherapy in the BEP regimen. Patients with an unfavorable decline of STMs subsequently received 4 cycles of TIP regimen (paclitaxel 120 mg/m² on days 1 and 2 + ifosfamide 1500 mg/m² on days 2-5 (+ mesna) + cisplatin 25 mg/m² on days 2-5 + G-CSF). In the presence of residual tumors larger than 1 cm and the technical feasibility of removal, surgical treatment was performed. The primary endpoint was one-year PFS.Results. From 2017 to 2023, 34 patients were included in the study. Enrollment was prematurely closed due to an extremely low likelihood of achieving the primary endpoint. One-year PFS and overall survival (OS) were 57.1% and 74.4%, respectively. The favorable response rate (complete response + partial response with normalization STM) was observed in 55,8% of patients. Disease progression was observed in 21 patients, with the central nervous system being the first site of progression in 8 (37%) of them. Surgical treatment was performed in 16 patients, with viable tumor obtained in 4 patients. Conducting the first cycle in a "stabilization" mode for ultra-high-risk patients did not affect PFS (p = 0.28) or OS (p = 0.434). The toxicity profile of the TIP regimen was acceptable.Conclusion. Switching from BEP to TIP for patients with nonseminomatous GCTs and an unfavorable decline of STMs did not demonstrate efficacy. Further exploration of alternative therapeutic approaches is needed to improve treatment outcomes.
Exploring adoption dynamics
Authors: Musungwini Samuel , Van Zyl Izak , Kroeze Jan 
Published: February 2025

There is a lack of acceptance, adoption and sustained use of mobile phones for agricultural purposes by smallholder farmers in Zimbabwe, but the reasons for this have not been critically explored. In this study, the authors used a naturalistic methodology to help uncover the nuances of adoption dynamics among smallholder farmers in Gokwe South District, Zimbabwe. Data was gathered from in-depth interviews and focus groups. The findings suggest that gender, age, land ownership size, farming experience, mobile device ownership, and the period of owning a mobile device are critical precursors to adoption and use. Furthermore, digital proficiency and literacy, affluence, mobile technology services cost and telecommunication infrastructure availability are vital in achieving continuous, sustainable use of mobile technology in the Zimbabwean agricultural sector. This research has practical implications for policy and practice and may inform national legislation encouraging the increased use and affordability of mobile devices in the local agricultural sector. The research also makes a theoretical contribution in terms of unpacking the key factors that inhibit the adoption of mobile technology in marginalised settings.

Published: February 2025

Simultaneous Localization and Mapping (SLAM) is a crucial component to the push towards full autonomy of robotic systems, yet it is computationally expensive and can rarely achieve real-time execution speeds on embedded platforms. Therefore, a need exists to evaluate the performance of SLAM algorithms in practical embedded environments – this paper addresses this need by creating prediction models to estimate the performance that ORB-SLAM3 can achieve on embedded platforms. The paper uses three embedded platforms: Nvidia Jetson TX2, Raspberry Pi 3B+ and the Raspberry Pi 4B, to generate a dataset that is used in training and testing performance prediction models. The process of profiling ORB-SLAM3 aids in the selection of inputs to the prediction model as well as benchmarking the embedded platforms’ performances by using PassMark. The EuRoC micro aerial vehicle (MAV) dataset is used to generate the average tracking time that the embedded platforms can achieve when executing ORB-SLAM3, which is the target of the prediction model. The best-performing model has the following results 2.84%, 3.93%, and 0.95 for MAE, RMSE and R2 score respectively. The results show the feasibility of predicting the performance that SLAM applications can achieve on embedded platforms.
Lambert-Eaton Myasthenic Syndrome: A Review of Rare Neuromuscular Disease Related to Paraneoplastic and Autoimmune
Authors: Fardhani Ichlasul Mahdi , Graciella Cindy , Rayyan Muhammad Isra Rafidin 
Published: February 2025

Highlight:

LEMS is a rare neurological disease with fluctuating symptoms
Delays and misdiagnosis of LEMS disease often occur
The two main pathophysiologies of LEMS are autoimmune and paraneoplastic.

ABSTRACT
A rare condition known as Lambert-Eaton myasthenic syndrome (LEMS) affects the neuromuscular junctions, which are the connections between muscles and nerves. Tumor-associated or autoimmune causes trigger this condition. This mechanism depends on the presence of antibodies that directly attach to voltage-gated calcium channels located on the presynaptic nerve terminals. LEMS disease is divided into non-paraneoplastic or non-tumor LEMS (NT-LEMS) and paraneoplastic LEMS (P-LEMS). NT-LEMS is believed to be caused by an autoimmune process. On the other hand, P-LEMS has an underlying tumor, and LEMS symptoms are paraneoplastic manifestations of the tumor. Clinical signs of LEMS include proximal muscle weakness, autonomic dysfunction, and decreased deep tendon reflexes. The predominant sign of LEMS is weakness of the lower extremities. The defining characteristic of LEMS is a weakness that spreads from caudal to cranial, causing oculobulbar manifestations, and from proximal to distal, potentially involving the feet and hands. The diagnosis of LEMS depends on clinical, electromyographic, and serological findings of anti-VGCC antibodies. Therefore, comprehensive oncologic screening and monitoring should promptly follow a diagnosis of LEMS. The standard approach to treating LEMS symptoms is administering drugs that improve neurotransmission, such as potassium channel blockers and amifampridine. In refractory cases, immunosuppressants or immunomodulator agents, such as a combination of prednisone and azathioprine, are used. If a tumor is detected, oncological therapy should be a priority.
Deep Learning–Assisted Multiobjective Optimization of Geological CO2 Storage Performance under Geomechanical Risks
Authors: Zheng Fangning , Ma Martin , Viswanathan Hari , Pawar Rajesh , Jha Birendra , Chen Bailian 
Published: February 2025

Summary
In geological CO2 storage, designing the optimal well control strategy for CO2 injection to maximize CO2 storage while minimizing the associated geomechanical risks is not trivial. This challenge arises due to pressure buildup, CO2 plume migration, the highly nonlinear nature of geomechanical responses to rock-fluid interaction, and the high computational cost associated with coupled flow and geomechanics simulations. In this paper, we introduce a novel optimization framework to address these challenges. The optimization problem is formulated as follows: maximize total CO2 storage while minimizing geomechanical risks by adjusting the injection schedules within bounded constraints. The geomechanical risks are primarily driven by injection-induced pressure build-up, which is characterized by ground displacement and the induced microseismicity. We used the Fourier neural operator (FNO)-based deep learning model to construct surrogate models, replacing the time-consuming coupled flow and geomechanics simulations for evaluating the aforementioned objective functions. The developed surrogate models have been incorporated into a multiobjective optimization framework through a genetic algorithm to reduce the computational burden. The proposed optimization framework reduces the computational cost from approximately 2,400 hours, when using objective function evaluations based on physics-based simulations, to around 20 minutes. A set of Pareto-optimal solutions of the proposed workflow yields nontrivial optimal decisions, reducing the microseismicity potential and the vertical displacement. This Pareto front highlights the optimal trade-offs between CO2 storage amount, safety, and ground displacement, emphasizing the need for careful optimization and management of injection strategies to achieve a balanced outcome. The novelty of this work is twofold. First, we demonstrate the importance of incorporating the minimization of the geomechanical risks as objective functions into the CO2 storage optimization workflow to mitigate the potential risk of induced microseismicity and ground displacement. Second, we leverage the FNO-based surrogate models to optimize a real-field CO2 storage operation.

Abstract

Quantum metrology has emerged as a powerful tool for timekeeping, field sensing, and precision measurements within fundamental physics. With the advent of distributed quantum metrology, its capabilities have been extended to probing spatially distributed parameters across networked quantum systems. However, generating the necessary non-local entanglement remains a significant challenge, and the inherent incompatibility in multi-parameter quantum estimation affects ultimate performance. Here we use a superconducting quantum network with low-loss interconnects to estimate multiple distributed parameters associated with non-commuting generators. By employing high-fidelity non-local entanglement across network nodes and a sequential control strategy, we accurately estimate remote vector fields and their gradients. Our approach achieves an improvement of up to 6.86 dB over classical strategy for estimating all three components of a remote vector field in terms of standard deviation. Moreover, for the estimation of gradients along two distinct directions across distributed vector fields, our distributed strategy, which utilizes non-local entanglement, outperforms local entanglement strategies, leading to a 3.44 dB reduction in the sum of variances.
Advancing Molecular Insights: A Global Systematic Review and Meta-analysis of Epidemiology and Drug Resistance Patterns of Mycobacterium tuberculosis in Sputum Samples
Authors: Bohara Madan Singh , Bhatta Dwij Raj 
Published: February 2025

Abstract

Background
Tuberculosis (TB), caused by Mycobacterium tuberculosis (Mtb), remains a leading cause of morbidity and mortality globally. The emergence of multidrug-resistant (MDR-TB) and extensively drug-resistant TB (XDR-TB) presents significant challenges for TB control. Molecular diagnostics and epidemiological studies provide critical insights into the genetic diversity and drug resistance of Mtb, yet regional variability and fragmented data complicate global understanding.
Materials & Methods
Following PRISMA guidelines, a systematic search of PubMed, Google Scholar, and ScienceDirect identified peer-reviewed articles published between 2018 and 2023. Thirteen studies met the inclusion criteria, encompassing 3469 isolates from diverse regions. Key variables included drug resistance patterns, phylogenetic lineages, and demographic data. Statistical analyses included meta-analysis of proportions, heterogeneity assessments, and publication bias evaluation.
Findings:
MDR-TB prevalence ranged from 1.5% in Kenya and Mexico to 34.4% in India. Resistance to rifampicin and isoniazid showed pooled prevalence rates of 2.9% and 6.2%, respectively, with significant geographical variability. Phylogenetic analyses revealed distinct lineage distributions: lineage 3 predominated in India, lineage 2 was prevalent in China, and lineage 4 dominated in Ethiopia and Ghana. Age and gender analysis indicated a higher proportion of male TB patients, with significant variability across studies.
Conclusion
This study highlights the global heterogeneity in TB drug resistance and genetic diversity. Tailored regional strategies, informed by molecular epidemiology, are essential to address the rising threat of MDR-TB and enhance TB control efforts.
