Published: January 2025

Abstract
Shale gas reservoir has the characteristics of low porosity and permeability, so it can only be put into development by hydraulic fracturing in engineering. However, the current research on the relationship between flowback rate and production is still unclear, so it is necessary to conduct a deeper study on reservoir imbibition characteristics. In this study, a mathematical model is put forward to guide the imbibition experiment, and finally a simple method of engineering research scheme of reservoir imbibition characteristics in the study area is obtained. This method relies on the working steps of “grey correlation analysis → imbibition experiment → sampling inspection” and obtains the following conclusions. When the core water saturation of the reservoir in the study area is less than 30%, the water in the pores is bound water, and it begins to hinder the seepage channel. This conclusion can guide the setting of backflow rate in engineering and continue to compare fracturing fluids with different formulations with the help of the current test bench in the next research. On the premise of considering the influence of shale hydration on microscopic pore structure, the influence of fracturing fluid system on shale imbibition is further discussed.

Published: January 2025

Abstract

Automated systems that analyze short conversation samples could offer valuable insights into autistic children's real-world social communication competence while highlighting opportunities for growth. In this study, we explore the potential of using large language models (LLMs) to assess social interaction quality during casual conversations that include autistic youth. We focus on evaluating the ability of LLMs to predict conversation quality, with the long-term goal of informing tailored communication support strategies that promote optimal social outcomes. Results underscore the need for caution when using LLMs to inform clinical decision-making in autism.

Abstract

The growth and development of sunflower plants (Helianthus annuus L.) can be limited by salinity stress. The damage and changes caused by this stress can occur from germination to final production, depending on the tolerance of the species and salt concentrations. Therefore, techniques have been developed to promote greater seed vigor and seedling development in these conditions. In this study, we aimed to understand the responses and changes in sunflower seedlings promoted by the application of halopriming in seeds. For this, sunflower seeds were subjected to priming with 50µM NaCl and control (without priming) and, sown in soil containing NaCl at concentrations of 0mM, 60mM, 120mM and 240mM. When presenting four fully expanded leaves, seedlings were collected and evaluated content of pigments of the photosynthetic apparatus, proteins, the marker of oxidative stress (MDA), osmoregulators such as proline and sugars and the enzymes of the antioxidant system ascorbate peroxidase (APX) and superoxide dismutase (SOD). Furthermore, growth parameters in leaves and roots were evaluated. Seedlings from primed seeds presented physiological and growth strategies to tolerate salinity. There was an increase in the length and dry matter of the roots and with the increase in saline concentrations there was consequently an increase in the levels of photosynthetic and accessory pigments. In addition, there was an increase in macromolecules and osmoregulatory molecules. In conclusion, halopriming of seeds promoted greater tolerance of seedlings grown under different salt concentrations.

Abstract

Background: COVID-19 disease caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) is characterized by hypercoagulable state that results in an increased risk for embolic and thrombotic vascular complications. Incidence of pulmonary embolism (PE) in COVID-19 varies between 20-30%.
Purpose: To determine predictors for treatment outcome in patients with COVID-19 and its associations with clinical and laboratory parameters.
Materials and methods: A retrospective observational single-center study was conducted between 1st of September 2021 and 24th of December 2021 involving 2111 patients admitted to the COVID Hospital "Batajnica", University Clinical Center of Serbia, Belgrade. Among them, 100 patients (4.74%) got diagnosis of pulmonary embolism by computed tomography pulmonary angiography (CTPA). Patients were divided in two groups. Study group (100 patients) with COVID-19 and PE and control group (100 patients) with COVID-19 but without PE.
Results: According to multivariate regression analysis, predictors of impaired outcome in COVID-19 patients are age (p<0.001, OR 1.134, 95% HR 1.062-1.211), C reactive protein level (CRP) (p=0.043, OR 1.006, 95% 1.000-1.013), invasive mechanical ventilation (p<0.001, OR 58.72, 95%HR 13.784-254.189), pulmonary embolism (p=0.025, OR 3.718, 95% HR 1.183-11.681), and hospitalization in intensive care unit (p=0.012, OR 9.673, 95% 1.660-56.363).
Conclusion: We report increased mortality and mechanical ventilation rates in COVID-19 patients with acute PE. Older age, elevated level of CRP, hospitalization in ICU, and PE present independent predictors for impaired outcome in COVID-19 patients.
Secure Sybil Attack Detection and Prevention in Distributed Wireless Sensor Networks using Hybrid APIT Localization Scheme combined with Quantum Key Distribution
Authors: Ahamad Firoj 
Published: January 2025

Abstract

Applications of wireless sensor networks (WSNs) such as geographical routing, location estimation, and target tracking require details about the location of the sensor nodes. There are several techniques based on range free localization such as DV-hop, centroid methods, SeRLoC, HiRLoc and APIT methods are available for localizing the sensor nodes. However, it is very essential for ensuring the sensor nodes that they can identify exact locations in WSNs. In general, wireless networks are more sensitive to security attacks due to the communication through wireless shared medium. Some of the common and frequent security attacks in WSNs are Jamming attacks, Sinkhole attack, Selective forwarding attack, Wormhole attack, Black hole attack, and Sybil attacks. Among these popular attacks, the Sybil attack is of the highest priority vicious security threat in WSN. Sybil attacks are characterized by their ability to forge multiple identities that have the power to deteriorate the localization process and augment the localization accuracy. This paper presents a hybrid Sybil free APIT (SF-APIT) localization approach combined with quantum key distribution (QKD) technique to detect the popular Sybil attack in WSNs. The major aim behind this work is to completely prevent the Sybil nodes in WSNs using APIT localization and quantum cryptography. Simulation results favor about the better performance of proposed approach for Sybil attack detection. This detection method is fully based on an special the approach of Received Signal Strength (RSS) in a distributed wireless localization environment.

Abstract

Piezoelectric nanocomposites have become increasingly popular in the field of energy harvesting systems. An investigation into PVDF electrospun nanocomposite membrane doped with varying weight percentages of Ce 3+ is presented. A blue shift in the bandgap of the ceria NPs was found by optical characterisation using absorbance analysis, which also enhanced UV absorption in the PVDF polymer. At some additive doses, luminosity analysis demonstrated an incremental fluorescence impact. But above a certain point, additional increases seemed to have quenching effects, which decreased fluorescence. FTIR examination of the composite nanofiber membrane showed that the inclusion of NPs increased the amount of β sheets; this was especially optimized at a 5% concentration of ceria NPs in the PVDF solution. This novel ultrasensitive PVDF with ceria 5wt % nanogenerator produced a maximum of 9 V at an applied load of 3 N at a frequency of 1.5 Hz whereas pure PVDF generated only 3 V which clearly proves the enhanced pizoactivity of PVDF Ceria based nanomembrane. The formed oxygen vacancies according to tri-valent cerium ions, which have been showed through optical characteristics, supports the nucleation of PVDF chains around ceria NPs. The resultant PVDF/ceria nanomembrane demonstrated a remarkable maximum power density of 89 mW/m2, demonstrating its load-bearing capability. With its dual functionality as an optical sensor and an energy harvesting unit, this adaptable nanocomposite shows potential for use in multifunctional devices.

Abstract

Pancreatic adenocarcinoma (PDAC) is one of the most lethal cancer types worldwide, with early diagnosis being challenging due to nonspecific symptoms that are often noticed only when the tumor reaches a large size. Liquid biopsy has emerged as a promising technology for cancer detection, where the identification of tumoral cell-free DNA (cfDNA) using sensitive methodologies can identify genetic mutations, allowing for tumor diagnosis, prognosis, and therapeutic approaches. In this study, we detected mutations in KRAS, TP53, CDK2A, and SMAD4 in the cfDNA of 55 pancreatic adenocarcinoma patients, using a total of 133 blood samples and next-generation sequencing (NGS). We found that extraction from 5 mL of plasma provided the minimum yield of tumor cfDNA for NGS in 69.18% of samples, highlighting the need for cfDNA concentration. Using NGS, we identified 11 pathogenic variants across 13 samples from 11 patients: 9 patients had mutated KRAS, 4 had mutated TP53, and 4 had mutated SMAD4. Additionally, we discovered a SMAD4 variant not previously associated with PDAC, which was significantly correlated with patient survival. Our data describe and discuss the properties of cfDNA extraction and yield for NGS and its clinical application. We demonstrate that liquid biopsy using NGS for cfDNA targeting KRAS, TP53, CDK2A, and SMAD4 represents a promising alternative for the early diagnosis and genetic profiling of PDAC, with implications for prognosis and targeted therapy.

Abstract

Shrimp shell biowaste used as a precursor effectively helps solve environmental problems related to waste management and provides a sustainable way to create valuable materials. This study investigates the synthesis and characterization of Carboxylated Chitosan Nanocrystals (ChsNCs) from shrimp shell biowaste while reducing the required chemical volumes. The process started with chitin synthesis from shrimp shells, followed by a controlled oxidation and carboxylation process to synthesize ChsNCs. The characterization of the synthesized ChsNCs began with the calculation of yield percentage to evaluate the efficiency of the synthesis process. Moreover, comprehensive characterization of synthesized ChsNC was conducted using Scanning Electron Microscopy (SEM), Energy Dispersive X-ray (EDX) analysis, X-ray Diffraction (XRD) spectroscopy, Thermal Analysis (TGA/DTA) and Fourier Transform Infrared (FTIR) spectroscopy to evaluate the morphological features, elemental composition, structural properties and thermal behaviour of the synthesized samples. The antibacterial properties of synthesized ChsNC were assessed against four bacterial strains using the well-diffusion method. The results show that the yield percentage and structural characterization confirmed the successful synthesis of ChsNC with reduced chemical volumes. Moreover, the synthesized ChsNC exhibits significant antibacterial activity, indicating larger inhibition zones at higher concentrations. The novelty of this research is the effective conversion of marine by-products of shrimp shell bio waste into ChsNCs with strong antibacterial properties by reducing the required chemical volumes. This study opens the way for broader applications of ChsNCs in biomedical and environmental fields, indicating a practical approach to developing biofunctional nanomaterials.

Abstract

Invasive non-native species are a major threat to seabirds, leading to the implementation of numerous eradication campaigns. However, eradication can also affect non-targeted species. There are concerns over the fact that the invasive mammal eradication using poisonous bait planned on Amsterdam Island might affect negatively the local population of subtropical brown skuas Stercorarius antarcticus hamiltoni. Here, movements of 21 adult brown skuas breeding at Amsterdam Island, southern Indian Ocean, its most northerly breeding site were studied during the non-breeding period using geolocation, in order to provide relevant information for conservation prior to the eradication program. Post-breeding movements of brown skuas vary considerably, ranging from residency on the breeding grounds to long-range migrations to reach distant northern non-breeding zones in the Southern Hemisphere. Most individuals remained in the Indian Ocean (with the exception of one that wintered in the Tasman Sea), targeting areas along a continuum from the subantarctic to the tropics. Wintering grounds were generally situated in productive dynamic upwelling waters or frontal systems, with brown skuas avoiding the less productive area of the South Subtropical Gyre in the Central Indian Ocean. Inter-individual differences were not fully explained by sex: if males and females exhibited differences in activity metrics, they did not differ in duration or distance reached during the non-breeding period. Feather isotopic values confirmed that the birds mainly moulted their body feathers in the wintering area. The low δ15N values of feathers grown in mixed subtropical-subantarctic waters suggest that skuas feed on low trophic level prey in these areas. Overall, our results provided relevant information for conservation, and in particular helped identify the optimal period for scheduling land-based operations for eradicating introduced species on Amsterdam Island.

Abstract

In this work, we measured heat capacity and enthalpy of formation of synthetic mimetite phases with composition Pb5(AsO4)3Cl0.8(CO3)0.1 Pb5(AsO4)3F, Pb5(AsO4)3Br0.8(CO3)0.1, Pb5(AsO4)3OH0.86(CO3)0.07, and Pb5(AsO4)3I0.45OH0.35(CO3)0.1. Heat capacity has been measured using relaxation calorimetry and differential scanning calorimetry in the temperature range of 2–298.15 K. The standard third-law entropy of phases in question, derived from the low-temperature heat capacity measurements, is S°298.15K = 638.9 ± 4.5, 627.8 ± 4.4, 639.7 ± 4.5, 630.5 ± 4.5 and 637.7 ± 4.5 J mol− 1 K− 1, respectively. The measured enthalpies of formation derived from acid solution calorimetry are − 3068.7 ± 9.4, -3001.4 ± 3.5, -2963.4 ± 9.2, -2919.1 ± 9.1, and − 2936.3 ± 8.7 respectively. Some of the thermodynamic values deviate from previously determined data, most likely because of carbonate substitution in our samples.

Abstract

Suicide continues to be a major public health concern among youth globally, particularly in low- and middle-income countries. However, predictive studies focusing on marginalized populations remain limited. This study aimed to analyze the contribution of psychiatric disorders and adverse life events on suicidality within a clinical sample of economically disadvantaged Mexican youth. A total of 127 inpatient adolescents, aged 10 to 17 years, completed the MINI-KID interview to assess psychiatric disorders and suicidality and the Life Events Questionnaire for Adolescents. Machine learning techniques included classification tree, random forest, XGBoost and logistic regression. The mean area under the ROC curve of the classification tree, random forest, XG-Boost, and logistic regression models was .796, .820, .737, and .776, respectively. This analysis identified affective disorders and social, family, and health adverse life events, particularly losses, and victimization, as critical factors in suicidality. Addressing adolescent suicidality entail evaluating psychiatric disorders, and adverse events, with a particular focus on low-income families receiving public mental health care, especially in the context of developing countries.

Published: January 2025

Abstract

Background
Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) is a promising anti-tumor agent with selective cytotoxicity across a broad spectrum of tumor cell lines. In previous studies, we engineered a recombinant protein drug, SAC-TRAIL, which significantly enhanced the antitumor activity of TRAIL without exhibiting toxicity to normal cells. However, its application in cancer therapy is restricted due to poor resistance to proteolytic degradation and a limited in vivo half-life.
Methods and Results
To address these limitations, we designed a site-specific PEGylation method by conjugating methoxy-polyethylene glycol maleimide (mPEG-MAL) to the thiol group of specific cysteine residues on SAC-TRAIL. In this study, we optimized the PEGylation conditions for SAC-TRAIL, evaluated the in vitro activity and stability of mPEG-MAL-SAC-TRAIL, and conducted in vivo studies to assess its antitumor efficacy. It was shown that approximately 95% of SAC-TRAIL was PEGylated by mPEG-MAL within 30 minutes, exhibiting improved in vitro stability and antitumor activity. Furthermore, mPEG-MAL-SAC-TRAIL demonstrated enhanced anti-tumor activity and stability in an animal tumor model.
Conclusions
In summary, site-specific PEGylation at Cys-SH residues offers a promising strategy for extending the effective duration of SAC-TRAIL.

Abstract

Cadmium (Cd) contamination in agricultural soils poses a significant threat to soil quality and food safety. In-situ stabilization is an effective technology to remediate Cd contamination in soil. This study investigated the application of two functional vermicompost (VS and VB separately derived by vermicomposting cow dung added with struvite and biochar) as amendments in soils planted with celery (Apium graveolens L.). The objective was to evaluate their effects on celery growth, Cd migration, as well as the changes in physicochemical and biological properties in soil. The results indicated that, compared to no amendment (CK) and pure vermicompost (VK), the application of VS and VB enhanced celery growth including plant height, fresh weight, and chlorophyll content, etc. Additionally, functional vermicompost effectively retarded Cd migration from soil to celery by reducing its bioavailability coefficient and biological transport coefficient. Besides, the application of VS notably increased soil parameters as available nitrogen (AN), available phosphorus (AP), and the activities of β-glucosidase (β-GC) and sucrase (SU), while VB significantly improved cation exchange capacity (CEC), organic matter (OM), available potassium (AK) content and the activities of urease (UA) and catalase (CAT) in soil. Furthermore, the application of functional vermicompost enhanced bacterial diversity and richness in soil, while also increasing the relative abundance of metal-resistant bacterial taxa including Firmicutes, Proteobacteria and Myxococcota, etc. These findings indicate that both VS and VB have significant potential as effective remediation materials for Cd-contaminated soils, thereby supporting the development of sustainable agricultural practices and environmental restoration efforts.
