One-dimensional CsPbBr 3 superlattices with polarized and amplified spontaneous circularly polarized emissions
Abstract Nanocrystal superlattices typically occur in two- or three-dimensional configurations, constrained to the micrometer scale and with limited size tunability. Here, we report one-dimensional superlattices prepared by self-assembly of CsPbBr3 nanorods and nanoplatelets. These exhibit a hierarchical structure, evolving from ribbons (µm) of nanorods or nanoplatelets to assemblies of ribbons (mm).

Anisometropia at Age 7 Following Bilateral Secondary Intraocular Lens Implantation at 2 to Younger Than 6 Years for Pediatric Aphakia
Key Words Anisometropia Pediatric Cataract Secondary Intraocular Lens Implantation Introduction Pediatric cataract remains a leading cause of childhood visual impairment worldwide, and early surgical intervention is critical to prevent amblyopia.1,2 In infants and young children, primary intraocular lens (IOL) implantation is often deferred because of ocular growth, refractive unpredictability, and concerns about postoperative complications.3 Consequently, many children are managed with...

Mechanisms of dust generation, migration, and dispersion in fully mechanized excavation faces under long-compressive and short-suction ventilation during coal-cutting operations
Abstract Coal cutting in fully mechanized excavation faces produces high dust concentrations, which can be effectively controlled using a combined ventilation system with long forcing and short exhaust ducts. This study investigates the generation, transport, and diffusion of cutting-induced dust through integrated theoretical, experimental, and numerical approaches.

Social exposome and brain health outcomes of dementia across Latin America - Nature Communications
Abstract A multidimensional social exposome (MSE)—the combined lifespan measures of education, food insecurity, financial status, access to healthcare, childhood experiences, and more—may shape dementia risk and brain health over the lifespan, particularly in underserved regions like Latin America. However, the MSE effects on brain health and dementia are unknown.
Efficient hydrogenation of ketones and aldehydes catalysed by a well-defined PNNP-rhenium complex

Timing and intraindividual variability of daytime napping and Alzheimer’s disease in older adults - Communications Medicine
Abstract Excessive daytime napping has been associated with neurodegeneration in older adults, but prior research has focused on nap duration and frequency. Emerging frameworks emphasize the multidimensionality of sleep, but it remains unknown whether other dimensions of napping (e.g., timing, variability) are linked to neurodegeneration.
Visual Acuity and Complications at Age 7 Years Following Bilateral Secondary Intraocular Lens Implantation at 2 to Younger Than 6 Years for Pediatric Aphakia Key Points Question Are there differences in visual acuity and complication rates at age 7 years among children with bilateral aphakia who underwent a secondary intraocular lens implantation at different ages (2 to <3 years, 3 to <4 years, 4 to <5 years, and 5 to <6 years)?
Uncovering key factors in weight loss effectiveness through machine learning - International Journal of Obesity
Abstract One of the main challenges in weight loss is the dramatic interindividual variability in response to treatment. We aim to systematically identify factors relevant to weight loss effectiveness using machine learning (ML). We studied 1810 participants in the ONTIME program, which is based on cognitive-behavioral therapy for obesity (CBT-OB).
Daytime eating during simulated night work mitigates changes in cardiovascular risk factors: secondary analyses of a randomized controlled trial - Nature Communications
Abstract Effective countermeasures against the adverse cardiovascular effects of circadian misalignment, such as effects experienced due to night work or jet lag, remain to be established in humans. Here, we aim to test whether eating only during daytime can mitigate such adverse effects vs. eating during the night and day (typical for night shift workers) under simulated night work (secondary analysis of NCT02291952).

How can appropriate hue ranges be selected for sequential color schemes on choropleth maps? A quantitative evaluation using map-reading experiments
ABSTRACT We propose map-reading experiments to quantitatively evaluate the selection of hue ranges for sequential color schemes on choropleth maps. In these experiments, 42 sequential color schemes with six base hues and seven hue ranges were employed as experimental color schemes, and a total of 414 college students were invited to complete identification, comparison, and ranking tasks.

Structural inequality linked to brain volume and network dynamics in aging and dementia across the Americas - Nature Aging
Abstract Structural inequality, the uneven distribution of resources and opportunities, influences health outcomes. However, the biological embedding of structural inequality in aging and dementia, especially among underrepresented populations, is unclear.
Design of graphene-based chiral trifunctional tunable terahertz metasurface
Design of graphene-based chiral trifunctional tunable terahertz metasurface Driven by the pressing demand for integration and miniaturization within the terahertz (THz) spectrum, this research introduces an innovative approach to construct chiral structures using dichroicity as the target function. This initiative aims to tackle the prevalent issues of single-functionality, narrow application scope, and intricate design in conventional metasurfaces.

Imaging Ultra-weak UV Light Below 100 pW/cm² Using a 4H-SiC Photodetector with an Al2O3 Interfacial Layer
Imaging Ultra-weak UV Light Below 100 pW/cm² Using a 4H-SiC Photodetector with an Al2O3 Interfacial Layer Weak light detection is crucial in various practical applications such as night vision systems, flame monitoring, and underwater operations. Decreasing the dark current of a photodetector can effectively mitigate the noises, consequently enhancing the signal-to-noise ratio and overall weak light detection performance.

Nonpropagating ghost in covariant $f(Q)$ gravity
f(Q) gravity is an extension of the symmetric teleparallel equivalent to general relativity (STEGR). This work shows that based on the scalar-nonmetricity formulation, a scalar mode in f(Q) gravity has a negative kinetic energy. This conclusion holds regardless of the coincident gauge frequently used in STEGR and f(Q) gravity.

Circadian disturbances and frailty risk in older adults - Nature Communications
Abstract Frailty is characterized by diminished resilience to stressor events. It is associated with adverse future health outcomes and impedes healthy aging. The circadian system orchestrates ~24-h rhythms in bodily functions in synchrony with the day-night cycle, and disturbed circadian regulation plays an important role in many age-related health consequences.

An Optimal Operation Strategy of Regenerative Electric Heating Considering the Difference in User Thermal Comfort
Abstract : Regenerative electric heating has gradually become one of the main forms of winter heating with the promotion of “coal to electricity” project. By fully exploiting its regulating capacity, it can effectively achieve a win–win situation of “peak shaving and valley filling” on the grid side and “demand response” on the customer side.
