Alzheimer's Disease Co‐Pathology and Cognitive Impairment in Amyotrophic Lateral Sclerosis

open access: yesAnnals 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

Hematoma Interleukin‐1 Receptor Antagonist Concentrations Predict Long‐Term Outcome in Acute Human Intracerebral Hemorrhage

open access: yesAnnals of Neurology, EarlyView.
Objectives The interleukin (IL)‐1, IL‐6, and C‐reactive protein (CRP) pathway is central to the immune response after intracerebral hemorrhage (ICH). We tested for associations between hematoma and plasma cytokine concentrations and patient outcomes in Minimally Invasive Surgery Plus Rt‐PA for ICH Evacuation Phase III (MISTIE III) participants ...

B-Splines

open access: yes, 2019
BSplines are one of the most promising curves in computer graphics. They are blessed with some superior geometric properties which make them an ideal candidate for several applications in computer aided design industry. In this article, some basic properties of B-Spline curves are presented.

Branched splines

open access: yesCoRR, 2019
Spline functions have long been used in numerical solution of differential equations. Recently it revives as isogeometric analysis, which offers integration of finite element analysis and NURBS based CAD into a single unified process. Usually many NURBS pieces are needed to build geometrically continuous CAD models.

The morphology of the oval window in Paranthropus robustus compared to humans and other modern primates

open access: yesThe Anatomical Record, EarlyView.
Abstract The oval window (OW) is an opening connecting the inner and middle ear. Its area has been shown to consistently scale with body mass (BM) in primates, and has been used alongside semi‐circular canal (SCC) size to differentiate Homo sapiens and fossil hominins, including Paranthropus robustus.

The relationship between form and function of the carnivore mandible

open access: yesThe Anatomical Record, EarlyView.
Abstract Dietary morphology diversified extensively in Carnivoraformes (living Carnivora and their stem relatives) during the Cenozoic (the last 66 million years) as they evolved to capture, handle, and process new animal and plant diets. We used 3D geometric morphometrics, mechanical advantage, and finite element analysis to test the evolutionary ...

Functional models from limited data: A parametric and multimodal approach to anatomy and 3D kinematics of feeding in basking sharks (Cetorhinus maximus)

open access: yesThe Anatomical Record, EarlyView.
Abstract Basking sharks, Cetorhinus maximus (Gunnerus, Brugden [Squalus maximus], Det Kongelige Norske Videnskabers Selskabs Skrifter, 1765, vol. 3, pp. 33–49), feed by gaping their mouths and gill slits, greatly reorienting their cranial skeletons to filter food from water.

Boyanov-Naydenov problem and Kolmogorov type inequalities for positive (negative) parts of functions

open access: yesResearches in Mathematics
We prove that Boyanov-Naidenov problem $\|x^{(k)}_{\pm}\|_{q,\, \mu} \to \sup$ on classes of functions $\Omega^r_p(A_0, A_r):=\{x\in L^r_{\infty}: \|x^{(r)}\|_{\infty}\le A_r, L(x)_p\le A_0 \}$, where $k= 0,1,...,r-1$, $q \ge 1$ for $k\ge 1$, $q \ge p ...

Origin, evolution and biogeographic dynamics of the European rabbit (Oryctolagus cuniculus) in Southwestern Europe

open access: yesThe Anatomical Record, EarlyView.
Abstract The Pleistocene is a key period for understanding the evolutionary history and palaeobiogeography of the European rabbit (Oryctolagus cuniculus). The species was first documented in southeastern Iberia at the beginning of the Middle Pleistocene and appears to have rapidly spread throughout Southwestern Europe, where it was found in numerous ...

Controlled bending of a charged elastic cantilever in electric field

open access: yesВестник Самарского университета: Естественнонаучная серия
The bending of ultrathin single-layer metal plates in a controlled electric field is modeled. The plate (cantilever) form factor corresponds to elements of high-speed optical shutters in dynamic X-ray lithography.
