Loss of Pde6a Induces Rod Outer Segment Shrinkage and Visual Alterations in pde6aQ70X Mutant Zebrafish, a Relevant Model of Retinal Dystrophy

open access: yesFrontiers in Cell and Developmental Biology, 2021
Retinitis pigmentosa (RP) is one of the most common forms of inherited retinal degeneration with 1/4,000 people being affected. The vision alteration primarily begins with rod photoreceptor degeneration, then the degenerative process continues with cone ...

Entangleability of cones

open access: yes, 2021
We solve a long-standing conjecture by Barker, proving that the minimal and maximal tensor products of two finite-dimensional proper cones coincide if and only if one of the two cones is generated by a linearly independent set.

Aerobic Glycolysis Is Essential for Normal Rod Function and Controls Secondary Cone Death in Retinitis Pigmentosa

open access: yesCell Reports, 2018
Aerobic glycolysis accounts for ∼80%–90% of glucose used by adult photoreceptors (PRs); yet, the importance of aerobic glycolysis for PR function or survival remains unclear.

Anatomical differences between Pinus mugs Truro populations from the Tarts Mts.. expressed in needle traits and in needle and cone traits together

open access: yesActa Societatis Botanicorum Poloniae, 2014
Two-year-old needles were collected from 429 individuals of dwarf mountain pine (Pius mugn Turra) from 10 populations of this species growing in the Tatra Mts. (5 populations from calcareous and 5 from calcium-free undersoil).

Using optogenetics to dissect rod inputs to OFF ganglion cells in the mouse retina

open access: yesFrontiers in Ophthalmology, 2023
IntroductionLight responses of rod photoreceptor cells traverse the retina through three pathways. The primary pathway involves synapses from rods to ON-type rod bipolar cells with OFF signals reaching retinal ganglion cells (RGCs) via sign-inverting ...

Iron Cones in the Burials of Ulus Jochi: Aspects of Ethnocultural Identification

open access: yesНижневолжский археологический вестник, 2021
Cone-shaped objects, rolled from iron and bronze sheets, are found in the Golden Horde burials of the late 13th – early 15th centuries. The authors collected information on more than 100 burials with iron and bronze cones located in the territory of Ulus

Covering functionals of cones and double cones [PDF]

open access: yesJournal of Inequalities and Applications, 2018
The least positive number γ such that a convex body K can be covered by m translates of γK is called the covering functional of K (with respect to m), and it is denoted by Γm(K) . Estimating covering functionals of convex bodies is an important part of Chuanming Zong's quantitative program for attacking Hadwiger's covering conjecture.

The Analysis of Cones within the Tianwen-1 Landing Area

open access: yesRemote Sensing, 2022
On 15 May 2021, the Zhurong rover of China’s first Mars mission, Tianwen-1 (TW-1), successfully landed in southern Utopia Planitia on Mars. Various landforms were present in the landing area, and this area recorded a complex geological history. Cones are

Reflexive cones

open access: yes, 2012
Reflexive cones in Banach spaces are cones with weakly compact intersec- tion with the unit ball. In this paper we study the structure of this class of cones. We investigate the relations between the notion of reflexive cones and the properties of their
