Interfacial Modification of ZnO/ZnMgO Bilayer for Efficient and Stable InP Quantum Dot Light-Emitting Diodes via Ultraviolet Ozone Treatment.

The development of efficient charge transport layers is crucial for realizing high-performance and stable quantum dot light-emitting diodes (QD-LEDs). The use of a ZnO/ZnMgO bilayer as an electron transporting layer (ETL) has garnered considerable attention. This configuration leverages the high electron mobility of ZnO and the favorable surface state of ZnMgO.

Utilizing a compact diamino-based ligand as a charge balancer in quantum dot light-emitting diodes.

Charge imbalance within the emissive layer (EML) has been identified as a major obstacle to achieving high-performance quantum dot light-emitting diodes (QD-LEDs). To address this issue, we propose the use of a compact diamino-based ligand as a universal approach to improve the charge balance within the QD EML. Specifically, we treat QDs symmetrically with 1,4-diaminobutane (DAB) on both the bottom and top sides.

This study aimed to explore the factors and processes of self-management in deaf sign language users with hypertension.

Recent Progress on Quantum Dot Patterning Technologies for Commercialization of QD-LEDs: Current Status, Future Prospects, and Exploratory Approaches.

Colloidal quantum dots (QDs) are widely regarded as advanced emissive materials with significant potential for display applications owing to their excellent optical properties such as high color purity, near-unity photoluminescence quantum yield, and size-tunable emission color. Building upon these attractive attributes, QDs have successfully garnered attention in the display market as down-conversion luminophores and now venturing into the realm of self-emissive displays, exemplified by QD light-emitting diodes (QD-LEDs). However, despite these advancements, there remains a relatively limited body of research on QD patterning technologies, which are crucial prerequisites for the successful commercialization of QD-LEDs.

This study aims to investigate the lived experience of breast cancer among this group of young women.

Methods: Participants were purposefully selected from online communities and chat rooms in South Korea.

Age-related reductions in arousal-enhanced memory are moderated by trait emotion regulation.

Emotional arousal is known to enhance episodic memory in young adults. However, compared to valence, little is known about how healthy aging impacts arousal-enhanced memory effects. Furthermore, while emotion regulation is believed to improve with age, it is unclear how individual differences in emotion regulation influence arousal-enhanced memory.

Background: The Internet is considered an important channel for providing health information to older adults. We developed an intervention to improve eHealth literacy in older adults according to the information-motivation-behavioral skills (IMB) theory and Intervention Mapping. This study aimed to analyze the effect of a developed intervention on information, motivation, behavioral skills, and behaviors related to eHealth information in older adults.

Covid-19-Stress Associated With Worse Sleep Quality, Particularly With Increasing Age.

Objectives: Based on socioemotional selectivity theory, one might predict that older adults' well-being would be less negatively affected by coronavirus disease 2019 (Covid-19)-stress, as with other stressors, than younger people. However, whether sleep quality, which is negatively affected by aging, is similarly protected from the negative consequences of Covid-19-stress with age is unknown. Here, we examined the association between Covid-19-stress, above and beyond general-stress, and sleep quality and how it varies by age.

Purpose: The purpose of the study was to examine the factors associated with diabetes self-care behaviors (DSCB) in people with visual impairment (PVI), including demographics, disease-related characteristics, and psychosocial factors (self-efficacy, depression, and family support).

Methods: A descriptive cross-sectional study was conducted. Adults with visual impairment and diabetes were recruited online and through posting notices, and a total of 141 participants were included.

Comparative analysis of cancer gene mutations using targeted sequencing in matched primary and recurrent gastric cancers after chemotherapy.

Background: Investigation of responsiveness-associated genes using longitudinal mutation analyses after standard treatments in recurrent gastric cancer (GC) is limited.

Objective: To evaluate the somatic mutations associated with resistance to combined treatment involving fluorouracil (FU) or platinum (PL) in advanced GC.

Methods: Samples from patients with advanced GC treated with FU or PL alone, or surgery plus FU/PL, were studied.

Neural Reinstatement of Overlapping Memories in Young and Older Adults.

When we update our episodic memories with new information, mnemonic competition between old and new memories may result because of the presence of shared features. Behavioral studies suggest that this competition can lead to proactive interference, resulting in unsuccessful memory updating, particularly for older adults. It is difficult with behavioral data alone to measure the reactivation of old, overlapping memories during retrieval and its impact on memory for new memories.

Characterization and Health-Related Quality of Life in Older Adults With Disabilities According to Timing of Disability Onset.

The current study examined characteristics of early-onset and late-onset disability in older adults and identified predictors of health-related quality of life (HRQoL). This is a secondary data analysis of the 2017 national survey in South Korea. Participants were 4,014 older adults with disabilities, who were divided into an early-onset group ( = 2,229) and late-onset group ( = 1,785).

Spatial Movement Patterns and Local Co-Occurrence of Nutria Individuals in Association with Habitats Using Geo-Self-Organizing Map (Geo-SOM).

Nutrias () were imported to South Korea for farming in 1985; individuals escaped captivity and established wild populations in natural ecosystems in the late 1990s. Numerous studies have focused on their monitoring and management; however, information on the continuous movement of individuals is not available. In this study, telemetry data from field conditions were used to identify the nearest-neighbor distances of individuals in association with environmental factors, including plant type, land cover, and biological parameters.

Avalanche size distribution of an integrate-and-fire neural model on complex networks.

We considered the neural avalanche dynamics of a modified integrate-and-fire model on complex networks, as well as the neural dynamics in a fully connected network, random network, small-world network, and scale-free network. We observed the self-organized criticality of the neural model on complex networks. The probability distribution of the avalanche size and lifetime follow the power law at the critical synaptic strength.

Functional Brain Network Mechanism of Hypersensitivity in Chronic Pain.

Fibromyalgia (FM) is a chronic widespread pain condition characterized by augmented multi-modal sensory sensitivity. Although the mechanisms underlying this sensitivity are thought to involve an imbalance in excitatory and inhibitory activity throughout the brain, the underlying neural network properties associated with hypersensitivity to pain stimuli are largely unknown. In network science, explosive synchronization (ES) was introduced as a mechanism of hypersensitivity in diverse biological and physical systems that display explosive and global propagations with small perturbations.

Adenoviral pneumonia during etanercept treatment in a patient with rheumatoid arthritis.

Inhibitors of tumor necrosis factor-alpha (TNF-alpha) have been approved for treating rheumatoid arthritis. As one of the biological response modifiers, etanercept has also been used in the treatment of psoriatic arthritis and inflammatory bowel disease. While etanercept is effective, certain infectious complications, such as tuberculosis, fungus, and cytomegalovirus, have been reported.

A case of acute pneumonitis following talc pleurodesis: high-resolution CT findings.

Talc is one of the most effective agents for pleurodesis but it may induce serious pulmonary complication caused by pulmonary talc deposition. We describe a case of acute pneumonitis following talc pleurodesis in a 30-year-old woman who had malignant pleural effusion. Air-space consolidation and ground-glass attenuation developed in both lungs, predominantly in the ipsilateral lung, shortly after pleurodesis and were not satisfactorily explained by reexpansion pulmonary edema or pneumonia.
