Lead in diagenetic pyrite: evidence for Pb-tolerant bacteria in a red-bed Cu deposit, Quebec Appalachians, Canada

Abstract Diagenetic pyrite from the Silurian continental red bed-hosted Transfiguration cupriferous deposit in the Quebec Appalachians, Gaspé Belt, Canada, contains up to ~2% (m/m) Pb. This large Pb content in pyrite contrasts with experimental determinations that indicate solubility of <0.1% (m/m) PbS in pyrite at high temperature. The distribution of Pb in pyrite is heterogeneous, with plumbiferous domains occurringas patches and concentric growth layers alternating with Mn- and Mo-bearing zones. The plumbiferous pyrite is surrounded by As- and Cu-rich rims. This compositional heterogeneity, however, is elusive under normal backscattered-electron (BSE) imaging, but it can be recognized under high-gain BSE. Proton-induced X-ray emission (PIXE) confirms the presence of Pb. Plumbiferous pyrite with >0.1% (m/m) Pb has rarely been described; it is thus possible that plumbiferous pyrite may have been overlooked in metalliferous deposits worldwide. The plumbiferous pyrite from Transfiguration has a light S-isotope composition that is characteristic of bacterial sulphate reduction. We suggest that Pb in diagenetic pyrite indicates Pb-tolerant bacterial activity and, perhaps, constitutes a biosignature of bacterial tolerance to Pb in ancient sedimentary systems.
Network Analysis in Public Health: History, Methods, and Applications

Network analysis is an approach to research that is uniquely suited to describing, exploring, and understanding structural and relational aspects of health. It is both a methodological tool and a theoretical paradigm that allows us to pose and answer important ecological questions in public health. In this review we trace the history of network analysis, provide a methodological overview of network techniques, and discuss where and how network analysis has been used in public health. We show how network analysis has its roots in mathematics, statistics, sociology, anthropology, psychology, biology , physics, and computer science. In public health, network analysis has been used to study primarily disease transmission, especially for HIV/AIDS and other sexually transmitted diseases; information transmission, particularly for diffusion of innovations; the role of social support and social capital; the influence of personal and social networks on health behavior; and the interorganizational structure of health systems. We conclude with future directions for network analysis in public health.
Pathophysiology and Risk Factors of Pulmonary Hypertension in Patients with Thalassemia

Pulmonary hypertension (PH) is recently defined in terms of hemodynamic criteria by a mean pulmonary arterial pressure (mPAP) determined by right heart catheterization of more than 20 mm Hg at rest. It is considered the main cause of morbidity and mortality in patients with chronic hemolytic anemias including thalassemia. It results in right ventricular failure and premature unexpected death if left untreated. PH is classified according to the World Health Organization (WHO) into five groups. Thalassemia is included within group 5 PH which occurs due to an unclear and/or multifactorial etiology. The occurrence of PH in thalassemia patients has a bad impact on the prognosis of the disease and on the survival in those patients. The pathogenesis of PH in thalassemia patients is complex and multi-factorial. It is assumed to be due to multiple overlapping pathogenic mechanisms including chronic hemolysis, inflammation, oxidative stress, decreased nitric oxide (NO) bioavailability, iron overload due to frequent repeated blood transfusion, hypercoagulability, erythrocyte dysfunction due to splenectomy, and chronic tissue hypoxia resulting from anemia leading to high cardiac output state and increased pulmonary vascular resistance.
Fake News Detection Using Social Media User Network and Engagement Features

Today, social media has become a key source of news consumption, posing a crucial issue of disseminating and propagating a large volume of fake news. As manual fact-checking techniques are slow and time-consuming, automated fake news detection models that can efficiently manage vast volumes of information must be developed. While natural language processing and computational linguistics have been widely employed in previous research, they often prove inadequate for constructing robust models. By examining the behavior of social media users, this research incorporated user network and engagement features to capture the patterns of fake news propagation on social media. We aimed to examine these features from the understanding that users are influenced by social validation and homophily, which play a significant role in shaping their behavior within online social networks. These features are then incorporated into our proposed fake news detection model. Our experimental results have demonstrated the significance of these features, suggesting their usefulness and relevant effects in fake news detection. Overall, this research contributes to the ongoing efforts in combatting fake news by proposing and assessing the significance of user network and engagement features within a fake news detection framework.
Implementation of a "Next Generation" Activity-Based Travel Demand Model: The Toronto Case

Disaggregate, activity-based travel demand models have been promoted for several decades as being more behaviourally sound and, as a result, more policy sensitive demand forecasting tools than conventional aggregate, trip-based, â€œfour-stepâ€ procedures. In the past decade numerous operational models have been implemented in a number of US metropolitan regions as well as in Europe. This paper discusses the development and implementation within operational planning practice of the first fully activity-based travel demand model in Canada, the GTAModel V4.0 model system for the Greater Toronto-Hamilton Area (GTHA). Based on over a decade of research at the University of Toronto, â€œV4.0â€ has recently been used by the City of Toronto in a major study of transit infrastructure investment strategies. It has also been adopted by the City of Mississauga for use in future planning studies. The paper discusses the advantages of the disaggregate activity-based approach to travel demand modelling. It then provides a concise overview of the key features and procedures of the V4.0 model system, as well as a detailed bibliography of more detailed documentation of the model system. The paper then discusses the operational implementation of the model system and briefly describes the on-going first application of the implemented model system in the analysis of major rail transit investment alternatives for the City of Toronto. The paper concludes with a few â€œlessons learnedâ€ that may be useful for other Canadian urban regions considering the evolution to activity-based model system formulations for their operational use.

SELEÇÃO DE FRAGMENTOS PRIORITÁRIOS PARA A CRIAÇÃO DE UNIDADES DE CONSERVAÇÃO DO CERRADO NO ESTADO DE SÃO PAULO

Dois workshops foram realizados nos últimos anos para a indicação de áreas de Cerrado prioritárias para a conservação deste bioma, um deles exclusivo para o Estado de São Paulo. Cada área indicada por esses workshops, porém, geralmente contém um grande número de fragmentos e, naturalmente, não é possível transformar todos eles em unidades de conservação. O objetivo do presente estudo foi estabelecer critérios e indicadores, aplicando-os para a seleção de fragmentos remanescentes com alta prioridade para a conservação do Cerrado no Estado de São Paulo. Considerando que São Paulo já possui uma rede de áreas protegidas e que novas unidades de conservação têm sido criadas individualmente, desenvolveu-se um algoritmo cuja aplicação resultou em uma classificação hierárquica dos principais fragmentos segundo seu valor biológico para a conservação, como ferramenta de suporte à tomada de decisão. Oitenta e seis áreas foram avaliadas, segundo quinze indicadores agrupados em: atributos biofísicos, integridade dos recursos naturais e influências externas, dados estes obtidos em expedições de campo e a partir de interpretação de imagens de satélite, analisados mediante a rede já existente de unidades de conservação. São apresentados e descritos os fragmentos considerados prioritários pelo seu alto valor biológico e também alguns que se destacam por estarem sob forte ameaça.
Impact of Service Life Duration on Electric Losses in Power Transformers: An Analytical Review

Transformers of metal plants include numerous devices past their rater service life. Their ongoing operation is made possible by regular maintenance and backup. Defining the transformer replacement sequence is a relevant problem due to the high costs of such equipment. Another important problem is cutting electricity losses depending on the actual efficiency that reduces over the long service life. In the majority of papers, the transformer power parameter data is based on the no-load and short-circuit losses calculated using the rated values. These parameters change over time, thus, such calculations cannot be accurate. The authors suggest an efficiency assessment method based on experimental measurements and calculations using the obtained results. An experiment was conducted to assess the electric losses in the transformer that has been in operation for over 55 years. An increased steel loss and a 0.5% efficiency reduction were confirmed, which are not critical. Accounting for the electric loss changes is deemed feasible when the service life of a transformer is over 20 years. To prolong the service life, the authors suggest using online technical condition monitoring systems.
Integrated proteomics and metabolomics analysis of D-pinitol function during hippocampal damage in streptozocin-induced aging-accelerated mice

Purpose Diabetes can cause hippocampal damage and lead to cognitive impairment. Diabetic cognitive impairment (DCI) is a chronic complication of diabetes associated with a high disability rate; however, its pathogenesis and therapeutic targets are unclear. We aimed to explore the mechanism of hippocampal damage during diabetes and evaluate the potential role of D-pinitol (DP) in protecting hippocampal tissue and improving cognitive dysfunction. Methods DP (150 mg/kg/day) was administered intragastrically to streptozocin-induced aging-accelerated mice for 8 weeks. Hippocampal tissues were examined using tandem mass tag (TMT)-based proteomics and liquid chromatography-mass spectrometry (LC–MS)/MS-based non-targeted metabolomic analysis. Differentially expressed proteins (DEPs) and differentially regulated metabolites (DRMs) were screened for further analysis, and some DEPs were verified using western blotting. Results Our results showed that 329 proteins had significantly altered hippocampal expression in untreated diabetic mice (DM), which was restored to normal after DP treatment in 72 cases. In total, 207 DRMs were identified in the DM group, and the expression of 32 DRMs was restored to normal post-DP treatment. These proteins and metabolites are involved in metabolic pathways (purine metabolism, arginine and proline metabolism, and histidine metabolism), actin cytoskeleton regulation, oxidative phosphorylation, and Rap1-mediated signaling. Conclusions Our study may help to better understand the mechanism of diabetic hippocampal damage and cognitive impairment and suggest a potential therapeutic target.

Gender-Related Issues in the Management of Low-Back Pain: A Current Concepts Review

Background: Low back pain (LBP) is an emerging disease. This review aims to investigate the role of gender-related factors in the diagnosis, clinical, and surgical management of LBP. Methods: From January 2002 to March 2023, EMBASE, SCOPUS, OVID-MEDLINE, Google Scholar, PubMed, and Web of Science were searched to identify relevant papers for further analysis. Results: Fifteen papers were included in this review. Sex- and gender-related differences were analyzed regarding the following points: (1) LBP epidemiology; (2) LBP physiopathology; (3) conservative management of LBP; (4) major vertebral surgery for LBP. The conservative treatment of LBP highlights that women claim services later in terms of poorer health status than men. In the postoperative phase, female patients show worse LBP, quality of life, and disability, but equal or greater interval change, compared with male patients complaining of lumbar degenerative disease. Conclusions: LBP epidemiology and clinical outcomes, following conservative and surgical management of patients complaining of back pain, might depend on both sex- and gender-related factors. It is mandatory to assess gender-related indicators in patients referred to LBP and address them to improve their clinical outcomes and quality of life.

High-Isolation Wide-Band Four-Element MIMO Antenna Covering Ka-Band for 5G Wireless Applications

The wireless communication system is steered towards the millimeter wave spectrum to achieve low latency and high-speed data rate. The MIMO antennas aid in attaining a higher data rate. The prominent spectrum at millimeter wave is Ka-band, suitable for short-range communication. The <inline-formula> <tex-math notation="LaTeX">$\vert \text{S}$ </tex-math></inline-formula>-parameter<inline-formula> <tex-math notation="LaTeX">$\vert $ </tex-math></inline-formula> response and radiation pattern of the existing MIMO antenna at this band are relatively unstable. Hence it encouraged to design and develop a four-element MIMO antenna operating at Ka-band. The antenna is a circular ring shape with two concentric rings with a plus-shape stub overlayed on circular rings. The structure is developed in four-stage with the comprehension of characteristic mode theory (CMA). The proposed structure generated Mode 2 as an efficient mode, with minor Modes 3 and 5 contributing for resonance out of five modes. The overall antenna profile is <inline-formula> <tex-math notation="LaTeX">$3.27\lambda _{0} \times 3.74\lambda _{0}$ </tex-math></inline-formula> (where <inline-formula> <tex-math notation="LaTeX">$\lambda _{0}$ </tex-math></inline-formula> is the wavelength at a resonance frequency of 28 GHz). The novel decoupling structure has improved the isolation to 30 dB and increased the bandwidth. The antenna has an operating bandwidth of 24.1-30.9 GHz, with a maximum gain of 6.5 dBi. The <inline-formula> <tex-math notation="LaTeX">$\vert \text{S}$ </tex-math></inline-formula>-parameter<inline-formula> <tex-math notation="LaTeX">$\vert $ </tex-math></inline-formula> from all the ports has an exact and stable response. The proposed antenna has resulted in bidirectional radiation tilted at an angle of <inline-formula> <tex-math notation="LaTeX">$334^{0}$ </tex-math></inline-formula> and <inline-formula> <tex-math notation="LaTeX">$210^{0}$ </tex-math></inline-formula> in the XZ plane. In the YZ plane, it has a triple beam. The radiation pattern is also stable throughout the bandwidth. The proposed MIMO antenna has a symmetrical design, demonstrating the possibility of expansion to n-element MIMO through a six-element MIMO antenna design. The article also presents the channel capacity, path loss, and link margin calculation for designed antenna line-of-sight (LOS) communication. The antenna has been evaluated with diversity parameters such as ECC, DC, CCL, TARC, and MEG.
A Wideband Dual-Input Reconfigurable Doherty Power Amplifier for Mismatch Recovery

This paper presents a wideband dual-input reconfigurable Doherty power amplifier (DR-DPA) to compensate the effects of the load mismatch on the output power $(\mathrm{P}_{\mathrm{out}})$ and drain efficiency (DE). Through series/parallel mode reconfiguration, the DR-DPA demonstrates relative brilliant performance over the circle of VSWR 2:1. In addition, this mismatch resilience can be extended to wideband operation based on exchangeable gate biasing settings. Moreover, a digital dual-input structure is utilized to overcome imperfect cooperation between main and auxiliary PAs at turning-on point. To validate the proposed concepts, the prototype is designed for 1.7-2.7 GHz and tested with Continous-wave measurement. At a nominal 50 Ω load, the proposed DR-DPA demonstrates a saturation $\mathrm{P}_{\mathrm{out}}$ of 43-43.5dBm, a peak DE of 68%-75% and a 59%-68% 6-dB output back-off DE. Moreover, on a full-span 2:1 VSWR circle, the proposed PA realizes less than 1.2 dBm $\mathrm{P}_{\mathrm{out}}$ loss and a 6%-10.5% DE reduction.
Recognition of motor intentions from EEGs of the same upper limb by signal traceability and Riemannian geometry features

Introduction The electroencephalographic (EEG) based on the motor imagery task is derived from the physiological electrical signal caused by the autonomous activity of the brain. Its weak potential difference changes make it easy to be overwhelmed by noise, and the EEG acquisition method has a natural limitation of low spatial resolution. These have brought significant obstacles to high-precision recognition, especially the recognition of the motion intention of the same upper limb. Methods This research proposes a method that combines signal traceability and Riemannian geometric features to identify six motor intentions of the same upper limb, including grasping/holding of the palm, flexion/extension of the elbow, and abduction/adduction of the shoulder. First, the EEG data of electrodes irrelevant to the task were screened out by low-resolution brain electromagnetic tomography. Subsequently, tangential spatial features are extracted by the Riemannian geometry framework in the covariance matrix estimated from the reconstructed EEG signals. The learned Riemannian geometric features are used for pattern recognition by a support vector machine with a linear kernel function. Results The average accuracy of the six classifications on the data set of 15 participants is 22.47%, the accuracy is 19.34% without signal traceability, the accuracy is 18.07% when the features are the filter bank common spatial pattern (FBCSP), and the accuracy is 16.7% without signal traceability and characterized by FBCSP. Discussion The results show that the proposed method can significantly improve the accuracy of intent recognition. In addressing the issue of temporal variability in EEG data for active Brain-Machine Interfaces, our method achieved an average standard deviation of 2.98 through model transfer on different days’ data.
Design of a 140 GHz Sheet Beam Traveling-Wave Tube with a Cuttoff Sever

Oscillation suppression is one of the most critical issues in the design of sheet beam traveling wave tubes (SBTWTs). This paper adopts a cuttoff sever with a matching step and a Bragg reflector in the interaction circuit, to suppress the oscillation of the sheet beam staggered double-vane (SDV) SBTWT. At the same time, this scheme avoids potential risks caused by the traditional dielectric attenuation. Simulation results show the feasibility of this scheme in the design of a SBTWT.
