Summary: The potential advantages of P-WFS in ophthalmic imaging have not been fully realized, but a cost-effective AO correction method has been proposed in this study, which has been successfully applied to human retinal imaging.

Summary: The purpose of this study was to characterize the association between dark-adapted rod and cone sensitivity and retinal structure in PAX6-related aniridia. The results showed that both cone and rod sensitivity were higher in aniridia patients compared to healthy controls. Additionally, the outer retinal layer thickness in the central macula was found to be correlated with both final cone and rod thresholds.

Summary: Adapting to motion can change the perceived size of objects and impact visual acuity. Adapting to receding motion can make objects appear larger and improve acuity, while adapting to looming motion can make objects appear smaller but also result in a modest improvement in acuity. Individual changes in acuity are not correlated with perceived size changes following motion adaptation.

Summary: This study investigates the differences in oculomotor function and pupil response in individuals with post-COVID-19 condition (PCC) with cognitive deficits. The study found that fixation stability is poorer in COVID mild patients and the percentage of pupil area reduction/enlargement is reduced in COVID severe patients, while saccadic latencies are longer in both COVID mild and severe patients.

Summary: The study found that the amplitude of accommodation decreases linearly with age as complete presbyopia is approached, while the slope of the response/stimulus curve also decreases. Pupil size decreases with age but continues to constrict. Ocular spherical aberration is linearly related to accommodation response and decreases with age.

Summary: Light adaptation allows the vertebrate visual system to function in different lighting conditions. Through single-cell RNA sequencing, it was found that various retinal cell types, including Müller glial cells (MGs), undergo dynamic molecular changes and communicate with other cells during light adaptation. The thyroid hormone signaling pathway plays a role in coordinating this intercellular communication and adjusting mitochondrial respiration in response to light conditions.

Summary: The study focuses on dark matter models based on a gapped continuum, describing a mixture of states with continuous mass distribution using effective field theory. A specific weakly interacting continuum (WIC) model is considered, which successfully reproduces observed relic density and exhibits intriguing observational consequences such as continuous and cascade decays of dark matter states.

Summary: The tree density in virtual sportscape is a crucial factor for the benefits received by patients with generalized anxiety disorder (GAD) during exercise in the virtual environment. This study used metrics such as pupil size, fixation count, and time to examine the relationship between tree cover density and stress in the virtual environment. The findings suggest that GAD patients experience reduced stress when cycling in an environment with 20-35% tree density, and they spend more time observing tree elements in the sportscape.

Summary: This article proposes a new out-of-equilibrium production mechanism for light dark matter called resonance scanning. If the mass of dark matter evolved in the early Universe, resonant production could have occurred for a wide range of light dark matter masses today. The study shows that the relic abundance of dark matter can be produced through the Higgs portal, consistent with current experimental constraints.

Summary: This study compared the effects of 360-degree and focal endolaser retinopexy (ELR) on postoperative pupil diameter in patients undergoing pars plana vitrectomy (PPV) for rhegmatogenous retinal detachment (RRD). The results showed an increase in postoperative pupil diameter, with a greater change in the 360-degree ELR group. Moderate pupillotonia induced post-ELR was correlated to the extent of ELR and was less marked in pseudophakic eyes.

Summary: Non-canonical scalar fields with specific Lagrangian properties have the capability to exhibit dark matter-like behavior on small scales. By manipulating the potential term, the kinetic term can be utilized as dark matter while the potential term plays the role of dark energy later on. Simple potentials like V = V-0 coth(2) phi and Starobinsky-type potentials can unify dark matter and dark energy, and cascading dark energy models are also effective in this unification.

Summary: The study found that using a virtual reality smartphone-based head-mounted display (VR SHMD) device resulted in significant changes in visual parameters, while using smartphones had lesser effects. The subjective discomfort associated with dry eye and neurologic symptoms were more severe in the VR group compared to the smartphone group. There were no significant changes in refraction and choroidal thickness after the use of either of the two devices.

Summary: The newly developed extended-depth-of-focus AcrySof((R)) Vivity (TM) intraocular lens (IOL) shows promise in minimizing dysphotopsia, but has limitations in uncorrected near visual acuity (UNVA). A study found that pupil size is significantly associated with UNVA, suggesting that eyes with smaller pupils may benefit from UNVA.

Summary: In dryland soils, microbes utilize chemoautotrophic and heterotrophic pathways to transform Soil Inorganic Carbon (SIC) into Soil Organic Carbon (SOC). This previously neglected transformation process sheds light on the carbon conversion from SIC to SOC in dryland soils.

Summary: In this study, the Gaussian mixture (GM) model, an unsupervised machine learning technique, was used to construct a statistical gas-solid surface scattering model based on collisional data obtained from molecular dynamics (MD) simulations. The results showed that the GM model outperformed the traditional scattering kernel model in predicting the distribution of postcollisional velocities and accommodation coefficients.
