Comparison of Latitude Distribution and Evolution of Even and Odd Sunspot Cycles [PDF]

open access: yes, 2020
We study the latitudinal distribution and evolution of sunspot areas of Solar Cycles 12 – 23 (SC12–23) and sunspot groups of Solar Cycles 8 – 23 (SC8–23) for even and odd cycles.

Novel Combined Approach for Vision‐Preserving Iridociliary Tumour Excision in a Small‐Breed Dog: Contralateral Iris Excision With En‐Bloc Scleral Resection

open access: yesVeterinary Medicine and Science, Volume 12, Issue 2, March 2026.
• A 2.8 mm corneal paracentesis positioned opposite to the tumour location enabled fine iris scissors insertion for precise excision of tumour‐bearing iris tissue under miotic guidance with pilocarpine 2%. • A fornix‐based conjunctival peritomy 5 mm from the limbus and stepped scleral flap approach allowed circumferential deep scleral incision with 2–3

Neuroinflammation‐Associated Optic Structural–Functional Degeneration in Early Diabetic Optic Neuropathy

open access: yesJournal of Diabetes, Volume 18, Issue 3, March 2026.
OCT imaging assessments and visual tests, which were validated by pyroptosis of retinal ganglion cells (RGC) and upregulation of NLRP3 and GSDMD expression, established an early structure‐function‐pathology diabetic optic neuropathy (DON) model in high glucose & obesity mice. Early retinal nerve fiber layer (RNFL)/total retinal thickness (TRT) thinning

Personalized Models of Biological Barriers and Their Diseases: Recent Progress with Organs‐On‐Chips

open access: yesAdvanced Biology, Volume 10, Issue 2, February 2026.
Buck and Bugter et al. explore the architectural diversity and physiological functions of human barrier systems and reveal how organ‐on‐chip platforms, particularly those integrating patient‐derived cells, are advancing barrier disease modeling. They highlight how emerging biological and technological advances can be used to bridge the gap between ...

Addressing Known Challenges in Solar Flare Forecasting I: Limb‐Flare Prediction With a 4π Full‐Heliosphere Framework

open access: yesSpace Weather, Volume 24, Issue 2, February 2026.
Abstract A demonstrated failure mode for operational solar flare forecasting is the inability to forecast flares that occur near, or just beyond, the solar limb. To address this shortcoming, we develop a “4π $4{\uppi }$” full‐heliosphere event forecasting framework and evaluate its statistical classification ability against this specific challenge.

MSC‐Derived Exosomal lnc‐AGT‐3: A Novel Anti‐Angiogenic Target in Age‐Related Macular Degeneration Through p53 Signaling Pathway

open access: yesAging Cell, Volume 25, Issue 2, February 2026.
MSC‐derived exosomes deliver lnc‐AGT‐3 to vascular endothelial cells, where it binds hnRNP K in the nucleus. This interaction inhibits p53 ubiquitination, enhancing p53 stabilization and transcriptional activation of anti‐angiogenic targets TSP1. Consequently, p53‐mediated signaling is potentiated, effectively suppressing choroidal neovascularization ...

Welfare Gains and Losses in Sunspot Equilibria [PDF]

open access: yes
We study a standard two period exchange economy with one nominal asset. As is well known there is a continuum of sunspot equilibria around each efficient equilibrium.

Comparison of the Variations of Sunspot Number, Number of Sunspot Groups, and Sunspot Area, 1875 -2013 [PDF]

open access: yes, 2014
Examined are the yearly variations and ratios of sunspot number, the number of sunspot groups, and the total corrected sunspot area for the interval 1875-2013.

Single‐Cell RNA Sequencing of Retina Reveals Nna1 Upregulation in Myopic Diabetic Retinopathy as a Protective Factor Against Diabetic Damage

open access: yesAdvanced Science, Volume 13, Issue 5, 27 January 2026.
This study investigates a schematic overview of the mechanistic pathways. The relationship between myopia and DR has long been of clinical interest. In diabetic mice, Nna1 expression is downregulated, whereas in diabetic mice with FDM, Nna1 expression is upregulated–particularly in Müller cells–accompanied by decreased vascular endothelial growth ...

Investigating the Role of Zebrafish Retinoschisin Homologs Rs1a and Rs1b During Retinal Development

open access: yesDevelopmental Neurobiology, Volume 86, Issue 1, January 2026.
ABSTRACT Deficiency in the retinoschisin protein (RS1) causes X‐linked juvenile retinoschisis (XLRS), a retinal degenerative disease that disrupts retinal layers and forms cystic cavities. In addition to its structural function, RS1 is believed to play a role in retinal development.
