AI Article Synopsis
- - The study focused on the electrical and magnetotransport properties of nanocrystalline tin dioxide films, analyzing performance across temperatures from 4 to 300 K and under magnetic fields up to 8 T.
- - The films were created using reactive DC magnetron sputtering of tin with subsequent temperature annealing, and their rutile structure was confirmed through X-ray diffraction analysis.
- - The findings included explanations of resistance and negative magnetoresistance using a model that incorporates quantum corrections, revealing that the weak localization in the films exhibited a three-dimensional character based on the evaluated electron dephasing length.
Article Abstract
The electrical and magnetotransport properties of nanocrystalline tin dioxide films were studied in the temperature range of 4-300 K and in magnetic fields up to 8 T. SnO films were fabricated by reactive direct current (DC) magnetron sputtering of a tin target with following 2 stage temperature annealing of synthesized samples. The nanocrystalline rutile structure of films was confirmed by X-ray diffraction analysis. The temperature dependences of the resistance () and the negative magnetoresistance (MR) were explained within the frame of a model, taking into account quantum corrections to the classical Drude conductivity. Extracted from the () and () dependences electron dephasing length values indicate the 3D character of the weak localization (WL) in our samples.

Depression and anxiety in people with kidney disease: understanding symptom variability, patient experience and preferences for mental health support.
J Nephrol
January 2025
School of Life and Medical Sciences, University of Hertfordshire, College Lane Campus, Hatfield, UK.
Article Synopsis
- The study investigates the prevalence and factors related to depression and anxiety among individuals with chronic kidney disease (CKD) in the UK, revealing that significant portions experience these mental health issues.
- Participants completed an online survey that assessed mental health history and treatment preferences, finding that over half had a history of diagnosed depression and many preferred in-person support.
- The results indicated that certain demographics, including age and gender, as well as factors like self-efficacy and current treatment, were significantly related to the levels of depression and anxiety symptoms, but differences in symptoms were not influenced by the kidney service centers’ location or size.
Investigation of the Relationship Between Intolerance of Uncertainty, Metacognitions, Maladaptive Coping, and Fear of Cancer Recurrence via Moderated Mediation Model.

Objective: In recent years, many studies have investigated the triggers, perpetuating factors, and outcomes of Fear of Cancer Recurrence (FCR), highlighting its complexity with multiple dimensions that encompass both antecedents and consequences. In this sense, the cognitive approach to FCR has explored variables such as metacognition, maladaptive coping strategies, and intolerance of uncertainty (IU). On the other hand, the findings of a restricted number of studies investigating the relationship between FCR and stated variables appear to be inconsistent.

Many viruses of the Flaviviridae family, including the Zika virus (ZIKV), are human pathogens of significant public health concerns. Despite extensive research, there are currently no approved vaccines available for ZIKV and specifically no live-attenuated Zika vaccine. In this current study, we suggest a novel computational algorithm for generating live-attenuated vaccines via the introduction of silent mutation into regions that undergo selection for strong or weak local RNA folding or into regions that exhibit medium levels of sequence conservation.

Background: Open inguinal hernia repair (OIHR) can be conducted under either general anesthesia (GA) or local anesthesia (LA). Despite a lack of evidence supporting improved perioperative outcomes, GA is the predominant anesthesia type used in OIHR. Frailty is defined as a clinically recognizable state of age-related increased vulnerability.

Climate change is increasing the frequency of large-scale, extreme environmental events and flattening environmental gradients. Whether such changes will cause spatially synchronous, large-scale population declines depends on mechanisms that limit metapopulation synchrony, thereby promoting rescue effects and stability. Using long-term data and empirical dynamic models, we quantified spatial heterogeneity in density dependence, spatial heterogeneity in environmental responses, and environmental gradients to assess their role in inhibiting synchrony across 36 marine fish and invertebrate species.
