The Anatomical Record, EarlyView.Abstract The present study reexamined the immunolocalization of membranous serotonin transporter (SERT) in the rat carotid body, and demonstrated SERT‐immunoreactive cells of unreported morphology. SERT was immunohistochemically localized in a very small population of cell clusters or single type I cells (2.8%) immunoreactive for synaptophysin, the ...

Numerical Linear Algebra with Applications, Volume 30, Issue 1, January 2023., 2023 Abstract Considering the space‐time adaptive method for parabolic evolution equations we introduced in Stevenson et al., this work discusses an implementation of the method in which every step is of linear complexity. Exploiting the tensor‐product structure of the space‐time cylinder, the method allows for a family of trial spaces given as spans of ...

Isoperimetric inequality for non-Euclidean polygons [PDF]
arXivIt is a classical fact in Euclidean geometry that the regular polygon maximizes area amongst polygons of the same perimeter and number of sides, and the analogue of this in non-Euclidean geometries has long been a folklore result. In this note, we present a complete proof of this polygonal isoperimetric inequality in hyperbolic and spherical geometries.

Helmeted hornbill cranial kinesis: Balancing mobility and stability in a high‐impact joint
The Anatomical Record, EarlyView.Abstract Prokinesis—in which a craniofacial joint allows the rostrum to move relative to the braincase—is thought to confer diverse advantages in birds, mostly for feeding. A craniofacial joint would, however, be a weak link if cranial stability is important. Paradoxically, we have identified a craniofacial joint in helmeted hornbills (Rhinoplax vigil),

Analysis of progressive fracture in fluid‐saturated porous medium using splines
International Journal for Numerical Methods in Engineering, Volume 124, Issue 1, Page 264-281, 15 January 2023., 2023 Abstract Powell‐Sabin B‐splines are employed to model progressive fracturing in a fluid‐saturated porous medium. These splines are defined on triangles and are 𝒞1‐continuous throughout the domain, including the crack tips, so that crack initiation can be evaluated directly at the tip.

A novel decision support system for designing and assessing phytoremediation‐to‐biofuel value chains
Biofuels, Bioproducts and Biorefining, EarlyView.Abstract The design of biofuel value chains is a complex process due to the large number of stakeholders involved, seasonality in feedstock availability, security of supply, logistics costs, efficiency considerations, and its multi‐node nature. Decisions on designing phytoremediation‐to‐biofuel value chains are even more complicated, due to the ...

International Journal for Numerical Methods in Engineering, Volume 124, Issue 2, Page 402-433, 30 January 2023., 2023 Abstract Edge‐based and face‐based smoothed finite element methods (ES‐FEM and FS‐FEM, respectively) are modified versions of the finite element method allowing to achieve more accurate results and to reduce sensitivity to mesh distortion, at least for linear elements. These properties make the two methods very attractive. However, their implementation
