Abstract
Anticipating volcanic eruptions remains a challenge despite significant scientific advancements, leading to substantial human and economic losses. Traditional approaches, like volcano alert levels, provide current volcanic states but do not always include eruption forecasts. Machine learning (ML) emerges as a promising tool for eruption forecasting, offering data-driven insights. We propose an ML pipeline using volcano-seismic data, integrating precursor extraction, classification modeling, and decision-making for eruption alerts. Testing on six Copahue volcano eruptions demonstrates our model’s ability to identify precursors and issue advanced warnings pseudoprospectively. Our model provides alerts 5–75 hr before eruptions and achieving a high true negative rate, indicating robust discriminatory power. Integrating short- and long-term data reveals seismic sensitivity, emphasizing the need for comprehensive volcanic monitoring. Our approach showcases ML’s potential to enhance eruption forecasting and risk mitigation. In addition, we analyze long-term geodetic data (Interferometric Synthetic Aperture Radar and Global Navigation Satellite System) to assess Copahue volcano deformation trends, in which we notice an absence of noteworthy deformation in the signals associated with the six small eruptions, aligning with their small magnitude.

Published: May 2024

IEEE 802.11 wireless network technologies are widely used to create corporate and personal local networks for data exchange and access to Internet resources. The main principle of operation of IEEE 802.11 networks is the principle of competitive access, according to which all wireless network users have the same access rights to the information transmission environment. This method of access leads to the occurrence of collisions in networks with a large number of users, which complicates the process of network functioning and leads to the degradation of quality indicators. The purpose of the study is to estimate the limit values of the operational characteristics of the IEEE 802.11 ac wireless network in the mode with the highest transmission rate (MCS8) in a frequency channel of 20 MHz with one spatial stream, provided that the network has a significant number of active stations with a saturated load. An alternative model of processes in IEEE 802.11 networks based on the concept of a virtual competitive window is used for research. According to the concept of virtual contention window (VCW), the process of data transmission in a network with competitive access is considered as a quasi-stationary process. Numerical data were obtained and graphs of channel bandwidth, transmission delay, and delay non-uniformity were given in the presence of one to sixteen active stations with a saturated load in the network, in the case of transmission of frames with a data volume of 512 or 1500 bytes. The maximum possible bandwidth of the channel with a frequency band of 20 MHz (68.387 bit/s) was determined, in the case of using frames with the maximum load (11454 bytes) provided by the standard. Estimated data on the number of collisions occurring in a network with a saturated load and the number of frames transmitted at various stages of channel access are also provided. The frame transmission delay increases almost proportionally to the number of active stations and varies from 0.605 ms to 5.293 ms, in the case of loading all data frames of 512 bytes, and from 0.785 to 6.41 ms, in the case of a load of 1500 bytes, for changes in the number of active stations in the network from 2 to 16. The unevenness of the delay exceeds the average delay and grows non-linearly, in the case of an increase in the number of active stations from 1 to 6 (CWmin=15), and linearly — with a further increase in the number of stations (over 6). The obtained results are useful for reasonable planning of wireless networks and configuration of network equipment parameters.

Published: May 2024

Background: Inflammation is an essential innate immune response aimed at antigen elimination and preventing their spread. Ginger (Zingiber officinale) and bangle (Zingiber cassumunar) rhizomes have been empirically utilized as medicinal components due to their anti-inflammatory potential. However, the combined efficacy of these rhizomes has not been previously explored.
Objective: This study aimed to assess the anti-inflammatory activity of a combination of ginger and bangle rhizome extracts.
Method: Ginger and bangle rhizomes were individually subjected to extraction through maceration with 96% ethanol, followed by purification with n-hexane. The anti-inflammatory activity was evaluated via motility tests on subjects administered orally with 1% CMC-Na (control), diclofenac sodium (4.5 mg/kg body weight), ginger ethanol extract (200 mg/kg body weight), bangle ethanol extract (400 mg/kg body weight), and a combination of both extracts (100:200 mg/kg body weight). Observations were made over 6 hours, with motility scores subsequently analyzed using ANOVA and the LSD test for statistical significance.
Results: Treatments involving ginger extract, bangle extract, and their combination significantly improved motility scores compared to the negative control. Furthermore, these treatments displayed no significant difference in effectiveness compared to the diclofenac sodium group (p > 0.05).
Conclusion: The combined ethanol extracts of ginger and bangle rhizomes demonstrate anti-inflammatory activity comparable to diclofenac sodium, as evidenced by motility score evaluations. This suggests their potential as alternative anti-inflammatory agents.

Published: May 2024

Human milk (HM) feedings are associated with reduced risks of neurodevelopmental and neurocognitive delays and systemic inflammatory diseases in infants born prematurely and/or at a low birth weight. Utilizing a neonatal piglet model, HM feedings were compared to bovine milk-derived infant formula (IF)-feedings with the aim of understanding the underlying mechanisms involved in reducing these risks. Six male piglets at postnatal-day (PD)2 were randomized into two feeding groups: HM-fed (n = 3) or IF-fed (n = 3) for 28 days. At 3- and 4-weeks-old, piglet memory and learning performance were assessed using novel object recognition (NOR). At PD30 piglets were euthanized, and whole brains were excised, weighed, and preserved for further analyses, and brain microglial morphology, and systemic inflammatory cytokines were quantified. During NOR, HM-fed piglets had significantly more non-novel revisits at both 3- and 4-weeks-old compared to IF-fed piglets. Microglia of HM-fed piglets had longer processes, more branch points, more endpoints, and a larger territorial volume compared to IF-fed piglets at PD30. In a neonatal piglet model, HM-feedings may improve cognition and reduce brain inflammatory response compared to IF-feedings.

<p><strong>Abstract.</strong>The surge in mask consumption during the COVID-19 pandemic led to the widespread use of disposable polypropylene masks for protection. However, the accumulation of used masks poses environmental challenges due to the slow degradation of polypropylene. Here, we investigate the potential of <em>Tenebrio molitor</em> larvae in degrading polypropylene masks, exploiting their synthetic polymer-breaking enzymes and associated microflora. In this study, we implemented various feeding strategies and established specific feed compositions to assess <em>T. molitor</em> larvae's consumption behavior towards polypropylene masks. Over a 21-day observation period, we noted a consumption rate of 0.4% of masks, with a 7.5% mortality rate among the larvae. The average daily consumption rate was 0.201 grams, resulting in a 2.3% increase in larval weight and the production of 0.4635 grams of feces. Our findings highlight the potential of <em>T. molitor</em> larvae as effective mask degraders. Optimizing cultivation conditions and feeding strategies may further enhance microbial diversity, potentially introducing more polypropylene degraders within <em>T. molitor</em>, thereby expediting mask degradation. This study emphasizes the promising role of <em>T. molitor</em> larvae in addressing the environmental challenges posed by the accumulation of polypropylene masks.</p><p><strong>Keywords: </strong></p><p>Mask, Degrade, <em>Tenebrio molitor</em>, Microflora, Polypropylene</p>
Demulsification of Water-in-Crude Oil Field Emulsion Using Green Demulsifier Based on Sesamum indicum: Synthesis, Characterization, Performance, and Mechanism
Authors: Dhandhi Yogesh , Bhardwaj Vaibhav , Saw Rohit Kumar , Naiya Tarun Kumar 
Published: May 2024

Summary
This paper addresses the issues related to poor demulsifier efficiency, low biodegradability, and toxicity of commonly used chemical demulsifiers in the petroleum industry. To overcome these challenges, this study proposes an environmentally friendly demulsifier synthesized from Sesamum indicum (sesame oil). The synthesized demulsifier is characterized using Fourier transform infrared (FTIR), nuclear magnetic resonance (NMR), and thermogravimetric analysis (TGA). The demulsification test was performed for the synthesized demulsifier through the standard bottle test method using water-in-oil field emulsion. The results indicate that the demulsifier has an excellent dehydration rate and can achieve a demulsification efficiency of 85% within 10 minutes at a concentration of 200 ppm and 100% efficiency in 60 minutes at 70°C and performs better than the commercial demulsifier. The paper summarizes the factors affecting the demulsification process, including settling time, temperature, and demulsifier concentration. Furthermore, the demulsification mechanism is explained through interfacial tension (IFT) measurement, competitive adsorption test between asphaltene and demulsifier, and rheology study of emulsion. Moreover, the disuccinimidyl sulfoxide (DSSO) demulsifier is tested for its biodegradability according to Organization for Economic Co-operation and Development procedure, and the results show that it is completely biodegradable. The outcome of this research provides a promising solution for the demulsification of field emulsions through eco-friendly and efficient demulsifier.

Published: May 2024

Abstract

Typical technologies that can convert waste heat into electricity include thermoelectrics, thermionic capacitors, thermo-cells, thermal charge cells, and thermally regenerative electrochemical cycles. They have small thermal-to-electrical conversion efficiency or poor stability, severely hindering the efficient recovery of waste heat. Herein, we successfully developed a thermally regenerative Zn-ion battery to work under Carnot-like mode to efficiently harvest waste heat into electricity. Through introducing Layered Double Hydroxides to modify battery’s anode reaction, a record absolute high temperature coefficient of 2.944 mV/K is achieved in NiHCF/Zn battery, leading to a high thermal-to-electrical conversion efficiency of 29.24% of the Carnot efficiency and an extraordinary energy efficiency of 104.11% when the battery is charged at 50 ℃ and discharged at 5 ℃. This work demonstrates that the thermally regenerative batteries can effectively harvest waste heat to provide a powerful energy conversion technology.

Published: May 2024

Abstract

Sterile alpha and Toll/interleukin-1 receptor motif containing 1 (SARM1), a nicotinamide adenine dinucleotide (NAD)-utilizing enzyme, mediates axon degeneration (AxD) in various neurodegenerative diseases. It is activated by nicotinamide mononucleotide (NMN) to produce a calcium messenger, cyclic ADP-ribose (cADPR). This activity is blocked by elevated NAD level. Here, we verified this metabolic regulation in somatic HEK-293T cells by overexpressing NMN-adenyltransferase to elevate cellular NAD, which resulted not only in inhibition of their own SARM1 from producing cADPR but, surprisingly, also in the 5–10 neighboring wildtype cells in mixed cultures via connexin (Cx)-43. Direct visualization of gap junction intercellular communication (GJIC) was achieved by incubating cells with a permeant probe, PC11, which is converted by SARM1 into PAD11, a fluorescent NAD analog capable of traversing GJs. Extending the findings to dorsal root ganglion neurons, we further showed that CZ-48, a permeant NMN analog, or axotomy, activated SARM1 and the produced PAD11 was transferred to contacting axons via GJIC. The gap junction involved was identified as Cx36 instead. This neuronal GJIC was demonstrated to be functional, enabling healthy neurons to protect adjacent axotomized axons from degeneration. Inhibition of GJIC in mice by AAV-PHP.eB-mediated knockdown of Cx36 in brain induced neuroinflammation, which in turn activated SARM1 and resulted in axon degeneration as well as behavioral deficits. Our results demonstrate a novel intercellular regulation mechanism of SARM1 and reveal a protective role of healthy tissue against AxD induced by injury or neuroinflammation.

Authors: Wadajo Abebaw Amare , Tadele Abraham Kassahu , Geremew Teketel Tadesse , Tesgera Tigist Gutema 
Published: May 2024

Abstract

Introduction
Rosai–Dorfman disease (RDD) is an uncommon, histiocytic lesion that presents most commonly in young patients as large, painless, cervical lymphadenopathy but can presented with generalized lymphadenopathy without cervical LN involvement . It is characterized by the overproduction and accumulation of histiocytes, primarily in the lymph nodes but extra nodal involvement may also occur. Tissue biopsy is the main diagnostic modality.Histopathology is required to confirm diagnosis of RDD. The clinical course is unpredictable regardless of treatment. Although in most cases RDD can be observed or treated with local therapies, some patients with refractory or multifocal disease experience morbidity and mortality. Considering the rarity of RDD presenting with out cervical lymphadenopathy we would like to report this case for the world and up to our knowledge it is the first case to be reported in our country.
Case presentation
Here, we report a rare case of RDD in a 28-year-old male patient who presented with generalized lymphadenopathy over bilateral axillary, epitrochlear and inguinal area for the past 1 year which was histomorphologically confirmed to be RDD he was treated with steroid and show partial response for the treatment.
Conclusion
RDD is a rare entity that is challenging in diagnosis and management. Clinicians and pathologists should have a high degree of suspicion for RDD in young patients with generalized lymphadenopathy even with no cervical lymph node involvement.
FNAC is very important non-invasive and cost effective modalities to rule out top clinical differentials of RDD like lymphomas.
Remote and In-person Supervised Exercise in Patients with Knee Osteoarthritis (RISE-KOA): study protocol for a non-inferiority randomized controlled trial.
Authors: Carvalho Maurício Tatsch Ximenes , Alberton Cristine Lima 
Published: May 2024

Abstract

Background: Knee Osteoarthritis is a prevalent joint condition resulting in years lived with disability. A first-line treatment recommended by clinical guidelines is the therapeutic exercise to control pain and improve physical function. One possible approach for exercise supervision is telehealth using video calls, as it can be an effective alternative to in-person physical therapy for treating musculoskeletal conditions, expanding community access to physical rehabilitation. In this scenario, this study will investigate whether a muscle-strengthening exercise program for the lower limbs supervised remotely via video calls is as effective as the same exercise applied in person for improving condition-specific patient-reported outcomes (PROMs), psychological well-being, sleep quality, functional performance, and quadriceps muscle architecture.
Methods: A RISE-KOA study is a parallel, two-armed, single-blinded protocol for a non-inferiority randomized controlled trial. Sixty-eight participants aged 45 years or more, with a symptomatic and radiographic diagnosis of unilateral or bilateral knee OA (grade II or III according to Kellgren & Lawerence) will be randomly assigned to a remote exercise group supervised by video calls or in-person exercise group supervised at a physiotherapy clinic. Both groups will receive the same muscle-strengthening exercises for the lower extremities for 12 weeks. Follow-ups will be conducted during treatment (6 weeks), after treatment (12 weeks), and 18 weeks after randomization. The primary outcomes will be pain intensity and physical function during (6 weeks) and after treatment (12 weeks). Secondary outcomes will be condition-specific PROMs, psychological well-being, sleep quality, functional performance, and quadriceps muscle architecture.
Discussion: We hypothesize that muscle strengthening exercise supervised remotely via videocalls willnot be inferior to in-person exercise at a physiotherapy clinic on primary and secondary outcomes in patients with knee OA.
Trial registration: The study was prospectively registered at ClinicalTrials.gov (NCT06101797. Registered on Oct 26, 2023).
Calibration of mathematical water quality modeling applied to a basin located in central region of the state of São Paulo, Brazil
Authors: Nakamura Carolina Harue , Silva Gustavo Henrique Ribeiro da 
Published: May 2024

Abstract

Mathematical water quality models are support tools widely used in the management of water resources, as they may provide a broad view of the water system studied. In this way, the present study aimed to calibrate the “State Water Resources Plan Application” (APERH), applied in the São Paulo State Water Resources Plan 2023–2030, at the Jacaré-Pepira River, located in the Jacaré/Tietê River Basin (BH-TJ), central region of the state of São Paulo. The calibrated parameters were biochemical oxygen demand (BOD), dissolved oxygen (DO) and total phosphorus (P), which results showed that k1, k2 and b4 coefficients were within the range of typical values described in the literature, while s5 was higher than typical ranges. When evaluating the adjustments of the curves estimated by APERH with water monitoring data from Environmental Company of São Paulo (CETESB), visual analysis showed that BOD and DO had satisfactory adjustments between the estimated data and monitored data, while P was adequate at two of the three monitoring stations. Through the statistical method, it was observed that both BOD and DO indicated reliability between the estimated and monitoring data, while P had the opposite result. Thus, there is an understanding that APERH achieved the proposed objectives of this study, obtaining a first knowledge of BH-TJ, since there is a lack of water quality modeling studies in this region. The next step of this study is to apply the calibrated parameters to all BH-TJ and introduce the sociohydrology concept in this basin.
Self-Transitioning or Other-Transitioning? The Positive Effects of LGBT College Students’ Positive Coping and Perceived Academic Support
Authors: Ma Chenwei , Li jiangyu 
Published: May 2024

Abstract

Stigmatization directed towards LGBTQ individuals poses a considerable threat to their psychological well-being. LGBTQ college students frequently report exposure to perceived stress and microaggressions. Research indicates that self-regulation and proactive coping mechanisms can act as a protective buffer against the stigma and bias faced by sexual minorities. Consequently, this study aimed to investigate whether and to what extent proactive coping and perceived academic support moderate the relationship between perceived stress specific to LGBTQ college students, their psychological well-being, and academic performance. The study involved the snowball sampling and online recruitment of 359 Chinese LGBTQ college students with a mean age of 20.65. Employing structural equation modeling analysis, the study revealed that a) proactive coping moderated the relationship between perceived stress and psychological well-being, and b) perceived academic support moderated the relationship between perceived stress and academic performance. These findings suggest that Chinese colleges should implement adequate support and counseling services to enhance the proactive coping abilities of LGBTQ students and create an academically supportive environment to alleviate the adverse effects of perceived stress on psychological well-being.
