Advanced Science, EarlyView.We developed the ASCAL pipeline, integrating complementary spatial transcriptomics, to construct a high‐fidelity mouse whole‐eye single‐cell atlas. Applying ASCAL to a retinal artery occlusion (RAO) model revealed spatially restricted immune activation localized to the ganglion cell layer and the selective depletion of a translationally active, outer ...

Alzheimer's Disease Co‐Pathology and Cognitive Impairment in Amyotrophic Lateral Sclerosis
Annals of Neurology, EarlyView.Objectives Amyotrophic lateral sclerosis (ALS) and Alzheimer's disease (AD) share neuropathological features, including tau, amyloid, and TDP‐43 pathology. This study investigated whether AD‐related pathological changes are associated with cognitive impairment ALS. Methods Cerebrospinal fluid (CSF total‐tau, phosphorylated‐tau, beta‐amyloid) and plasma

Lattices of Generalized Skyrmions [PDF]
, 2011 Generalized Skyrme systems are those which include both the Skyrme and the Skyrme-Faddeev models through an interpolating parameter \alpha \in [0,1] the former corresponds to \alpha=0 and the latter to \alpha=1.

Satellites and concordance of knots in 3–manifolds
, 2018 Given a 3-manifold Y and a free homotopy class in [S-1, Y], we investigate the set of topological concordance classes of knots in Y x [0, 1] representing the given homotopy class. The concordance group of knots in the 3 sphere acts on this set.

On Polynomial Invariants for Knots and Links [PDF]
, 1986 This thesis presents an investigation of many known polynomial invariants of knots and links. Following Alexander's original idea, we define another multi-indeterminant polynomial for links and show that it satisfies some of Torres' conditions.

Approximating ideal shapes with tight elements
, 2005 A variational approach is applied to the problem of finding the shortest curves in space separated by constant distance. Among particular extremal solutions are straight line, circular arc and double helix. Various knots and links may be assembled from

Early stages of tooth development in the harbor porpoise Phocoena phocoena
The Anatomical Record, EarlyView.Abstract Here we describe the stages of tooth development in toothed whales on the basis of the harbor porpoise (Phocoena phocoena). The aim of the study was to find out whether these stages are identical to those of other mammals analyzed so far although toothed whales are homodont and monophyodont.

On the number of tubes touching a sphere or a tube
, 2006 A problem is formulated about how many unit-radius tubes can toucha ball of given radius from the outside and from the inside. Upper bounds for themaximum numbers of contacts are obtained for both interior and exterior contacts.It is also shown that the ...

Archaeological Prospection, EarlyView.ABSTRACT Ancient Olympia was one of the most important sanctuaries and the venue for the Olympic Games in Greek and Roman times. Its remains are located in the Olympia Terrace (Peloponnese, Greece) at the present‐day confluence of the rivers Alpheios and Kladeos at the base of Mount Kronos.
