Self-esteem and Self-concept as Predictors of Social Anxiety in University Students
Authors: Hume Figueroa Miriam Ruth , Téllez Alanís Ma de la Cruz Bernarda 
Published: January 2025

Social anxiety is currently recognized as having an inverse relationship with self-esteem in university students. However, the effect of self-concept on this relationship has been little studied. This study explores the influence of self-esteem and self-concept (academic, social, emotional, family, and physical) on social anxiety, as self-reported by university students. It distinguishes between dimensions such as fear of public speaking/interacting with authority figures, interacting with strangers, interacting with the opposite sex, assertive expression of annoyance, disgust or displeasure, and sensitivity to criticism and embarrassment. The study employed a non-experimental, cross-sectional, and correlational design. Participants included 282 students from the faculty of education (58 men and 224 women), aged between 18 and 40 years. They completed the Social Anxiety Questionnaire for Adults, the Self-Esteem Scale, and the AF-5 Self-Concept Inventory. Multiple regression revealed that emotional and social self-concept predict most dimensions of social anxiety, often with a greater effect than self-esteem. The results suggest that students' perceptions of themselves have a more substantial impact on social anxiety than their self-assessed sense of worth. Intervention programs focusing on emotional and social self-concept, while accounting for individual, cultural, and gender differences, may effectively reduce social anxiety in this demographic.

Published: January 2025

AbstractBackground and AimsThe study of stigma contributes greatly to our understanding of individuals' experiences of mental disorders. Addictive disorders are often associated with public misconceptions of the disorder, which can contribute to shame, discrimination, and reticence to seek help. This review aimed to: (1) evaluate the nature, frequency, and prevalence of addiction stigma; (2) identify the correlates of addiction stigma; and (3) examine the psychometric qualities of addiction stigma measures.MethodsA search of Web of Science, PubMed, Scopus, PsycINFO, and PsycNet, had 5,515 results which were screened for eligibility using Covidence. Eligible papers were quantitative, peer-reviewed studies, which reported an outcome variable of stigma related to an addiction.ResultsA total of 99 studies were included in the review, including 70 studies of substance-based addictions, 19 studies of behavioral addictions, and 10 studies which examined both. Thirteen of the 20 studies examining the impact of familiarity with addiction reported that greater familiarity was associated with lower public stigma. Studies comparing substance and behavioral addictions (n = 5) typically reported greater public stigma towards vignettes depicting substance-based addictions than for behavioral addictions. Between 22% and 40% of individuals with an addictive disorder identified stigma as a significant barrier to seeking help; however, the relative importance of stigma among other barriers was unclear.Discussion and ConclusionsEvidence for countermeasures to prevent and/or reduce stigma is currently limited. Further research on the nature and prevalence of addiction stigma is needed to inform the development of effective clinical and public health countermeasures.

Published: January 2025

Summary
This paper aims to demonstrate the application of a new automatic geosteering method that combines probabilistic interpretation with artificial intelligence (AI) for look-ahead decision-making. We expand on our previous synthetic workflow by testing our geosteering robot, named “PluRaListic,” into a synthetic environment modeled after a commercial cloud-based geosteering environment from the ROGII Geosteering World Cup (GWC). This synthetic setup allows for comprehensive testing and validation of the robot’s capabilities in a controlled yet realistic setting, ensuring that the methodologies developed can be robustly assessed before potential deployment in real-world operations. Our automatic geosteering method combines a reinforcement learning (RL) algorithm with the particle filter (PF) method. PF continuously assimilates real-time log measurements obtained during geosteering operations, producing hundreds of most-likely geology interpretations. Simultaneously, RL uses the information gathered from PF outputs to optimize steering decisions. The robot implementation automatically collects the new well trajectory and logs and passes the latest data through the PF. The RL uses the most-likely interpretations to balance the short- and long-term steering priorities and outputs a single recommendation that the robot sends back to the synthetic environment. The operation of our robot significantly surpasses real-time operation requirements, making one steering decision in approximately 4 seconds, far below the 2-minute-per-stand drilling time allocated for the GWC. After running 1,000 simulations, the median outcome achieved 77.3% reservoir contact, placing the robot in the top 14% of human experts. Moreover, the robot’s best attempt surpassed all experts, highlighting its potential to exceed human expertise in optimal scenarios. This work represents a radical innovation in geosteering that contributes to the advancement of automated geosteering frameworks. Future developments will focus on improving the performance and reliability of our robot. We also aim to enable an interactive framework for seamless collaboration between human experts and the robot, combining human expertise and consistent AI decision-making to achieve more precise and efficient drilling operations.

Published: January 2025

Summary
Preformed particle gels (PPGs) have been broadly used in temporary plugging steering fracturing techniques. However, it is difficult to achieve both excellent mechanical and degradable properties in conventional PPGs. To address this issue, double crosslinked self-degradable preformed particulate gels (DCSPPGs) were prepared using starch, hydroxyethyl acrylate, and acrylamide, crosslinked with poly (ethylene glycol) diacrylate (PEGDA) and borax. The structure was characterized using Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), and scanning electron microscopy (SEM), confirming the successful preparation of DCSPPGs. The mechanical properties of DCSPPGs indicate that the elastic modulus of DCSPPGs reached 22 918 Pa, which is much higher than that of most similar particle gels. Meanwhile, DCSPPGs can be degraded to a low-viscosity liquid within 36 hours without any visible solid residues. It shows that DCSPPGs have excellent mechanical and degradation properties. In addition, this study systematically evaluated the effects of particle size, temperature, and monovalent (Na+) vs. divalent (Mg2+ and Ca2+) ions on the swelling and degradation properties of the DCSPPGs. These findings reveal that DCSPPGs maintain exceptional degradation performance in high-temperature (150°C) and high-salinity (30% NaCl) environments. Core displacement experiments showed that the maximum breakthrough pressure of the core after DCSPPGs sealing could reach 27.69 MPa and that the permeability injury rate of the core after degradation was only 3.55%. It shows that DCSPPGs have excellent sealing performance and minimal formation damage post-degradation.

Published: January 2025

Abstract

Objectives
To compare the effect of low-flow mask oxygenation (LFMO) with breathing training (BT) for psychogenic hyperventilation syndrome (PHVS), providing more options and evidence for clinical treatment.
Methods
A randomized double-blinded controlled experiment was registered in the Chinese Clinical Trial Registry on 01/06/2023 with a defined number (ChiCTR2300072044) and approved by the Ethics Committee of (REDACT) (GYZXLL2023070) and then conducted there from 10 May 2024 to 23 November 2024. Participants with PHVS were blindly randomized into the LFMO group and the BT group, then the LFMO group inhaled 3L/minute oxygen with the oxygen mask and breathed freely, while the BT group performed the breath training led by researchers face-on-face. The recovery length from PHVS, the Nijmegen Questionnaire score at fifteen minutes since the intervention, the Nijmegen Questionnaire score at the end of the intervention, and the comfort/tolerance score (participant rating via NRS) were collected as the primary outcome. The secondary outcome was measured by the mean breath rate during the recovery (Calculated by dividing the total number of breaths during the intervention by time) and laboratory results, including the PH, lactate, K+, Ca2+, PO2, and PCo2.
Results
Forty-five participants (all Asian) completed the study and were included in the analysis (21 for the LFMO group and 24 for the BT group), mainly female (75%, n=33). All demographic characteristics between the two groups are within the reasonable range and have no significant difference. However, significant differences were measured among the outcomes, including the oxygen index (480.22±29.64, 311.01±15.45, p<0.001), Mean breath rate during recovery (19.17±1.74,28.24±2.53, p<0.001), and the LFMO group showed significant advantages in both the length of recovery (22.94±2.81, p<0.001) and comfort/tolerance (5.86±1.24, p<0.001).
Conclusion
Compared to breath training therapy, the low-flow mask oxygenation is a more effective, comfortable, and easy-to-follow treatment for PHVS.

Abstract

Objectives: This study aimed to: (1) Rigorously validate the Chinese PrAS-S psychometrically; (2) Precisely determine pregnancy-related anxiety prevalence and severity among pregnant women; (3) Scrutinize its significant influencing factors.
Background: Given pregnancy-related anxiety’s importance for maternal mental health, we used PrAS-S for a cross-sectional study of 300 Urumqi pregnant women. We aimed to evaluate anxiety levels, analyze status and factors, and support clinical psychological nursing.
Methods: Employing convenience sampling, 300 pregnant women from three Urumqi tertiary hospitals were surveyed with general and Chinese PrAS-S questionnaires. Univariate and multiple linear regression analyses explored determinants and assessed the scale’s reliability and validity.
Results: The Chinese PrAS-S proved reliable and valid. CR values for differentiation were 9.670 - 18.920, I-CVI 0.83 - 1, Cronbach's α 0.778 - 0.906, and test-retest correlation coefficients 0.857 - 1. The prevalence of pregnancy-related anxiety was 61.67% (185/300). Age, marital status, gestational age, marital satisfaction, baby's gender expectation, and concurrent pregnancy complications had a profound impact.
Conclusions: The Chinese PrAS-S is a convenient, reliable tool for quickly assessing pregnancy-related anxiety. With a high incidence rate, preventive and intervention strategies, considering influencing factors, must be strengthened to protect pregnant women's mental health.

Abstract

Intensive immunosuppressive therapy (IST) can greatly improve the survival prognosis of severe aplastic anemia (SAA). Nevertheless, approximately 30% of SAA patients did not respond to initial IST treatment. For these patients, salvage treatment poses a challenge. Therefore, predicting the efficacy of IST for SAA at initial diagnosis and developing the optimal curative regimen may enhance treatment outcomes. Trisomy 8 is one of the most common cytogenetic abnormalities in myeloid neoplasms and the BCL6 corepressor (BCOR), a transcription factor, also plays a role in hematopoiesis by inhibiting differentiation toward the myeloid lineage. It is rare that trisomy 8 and BCOR mutation present simultaneously in SAA, which may predict the efficacy of IST for SAA independently. Herein, we presented a SAA patient with both trisomy 8 and BCOR mutation at diagnosis. The bone marrow (BM) aspirate showed hypocellular BM and the bone marrow biopsy revealed a severe hypocellular bone marrow (15% cellularity). The patient rapidly relieved with reduced transfusion and achieved response after IST treatment. Biopsy about 3 months following IST showed remission, and the volume of hematopoietic tissue reached 40%. BM aspirate showed improvement (Grade III). Cytogenetic analysis revealed a normal karyotype. NGS still revealed BCOR mutation, and complete blood cell count results were improved. In conclusion, we are the first to describe a rare case of SAA with both chromosome 8 abnormality and BCOR mutation in detail. Review of the literature showed that the coexistence of trisomy 8 and BCOR mutation may represent a new distinct entity in SAA.
A Kolmogorov–Arnold Compute-in-Memory (KA-CIM) Hardware Accelerator with High Energy Efficiency and Flexibility
Authors: Sudarshan Chirag , Manea Paul , Strachan John Paul 
Published: January 2025

Abstract

Kolmogorov-Arnold Networks (KAN) are an emerging AI model designed for AI+Science applications, offering up to 100x fewer parameters than conventional Multilayer Perceptrons (MLPs). KAN relies on computationally expensive non-linear functions, unlike MLPs, which are dominated by matrix multiplication. This limits KAN's compatibility with energy-efficient hardware accelerators like Compute-in-Memory (CIM), restricting it to energy-inefficient general-purpose chips. To address this gap, we propose KA-CIM, a memory-centric design for energy-efficient computation of KAN inference. We leverage the Piece-Wise Linear (PWL) approximation of non-linear functions to convert complex computations into Multiply-Accumulate (MAC) operations and pre-storing segment parameters, an approach suitable for memory-centric design. A specialized CIM unit dynamically routes inputs to appropriate PWL segments, while a crossbar array retrieves segment slope and intercept to execute the MAC operations. The tile partitioning feature facilitates higher PWL segments for improved accuracy without significant energy penalties. This architectural design facilitates efficient and flexible computation of arbitrary non-linear functions of KANs. Beyond KAN inference, KA-CIM's capability extends to multi-variable equations and derivative computations. KA-CIM achieves energy-delay products 1073x lower than CPU for non-linear operations. When executing KAN, it achieves 77x lower energy-delay product than a 100 TOPS/W CIM accelerator executing MLP for the same task.

Published: January 2025

Abstract

Accurate mapping of rubber plantations is essential to understanding where deforestation due to rubber production occurs. Wang et al.1 produced 10-meter resolution maps of mature rubber with a reported high overall classification accuracy (OA = 0.95 ± 0.02), indicating that more than 4 million hectares of forests have been converted to rubber plantations in Southeast Asia and parts of China since 1993. However, we have serious concerns about the accuracy of these maps, as our analysis indicates that the area estimates by Wang et al.1 are significantly inflated. This observation underscores the need for caution in using these high-resolution maps for specific applications, such as assessing deforestation linked to rubber consumption under the EU regulation on deforestation-free products.
