Homogenization of oxygen transport in biological tissues [PDF]
arXiv, 2014 In this paper, we extend previous work on the mathematical modeling of oxygen transport in biological tissues (Matzavinos et al., 2009). Specifically, we include in the modeling process the arterial and venous microstructure within the tissue by means of homogenization techniques.

The Anatomical Record, EarlyView.Abstract Megantereon was a widespread saber‐toothed felid from the Pliocene and Pleistocene of the Old World and North America, but its rarity in the fossil record makes it complicated to restore its life appearance. Lack of complete specimens makes it necessary to combine information from fossils of different individuals to reconstruct their facial ...

Clinical Anatomy, EarlyView.ABSTRACT The notable anatomical variability of the superficial fibular nerve (SFN) affects clinical and surgical procedures that involve it. The aim of this study was to analyze the course and branching patterns of the SFNs relative to bony landmarks to provide foundational data for surgical precision and thereby minimize iatrogenic injuries.

Added costs of insect-scale flapping flight in unsteady airflows [PDF]
arXiv, 2016 The aerial environment in the operating domain of small-scale natural and artificial flapping wing fliers is highly complex, unsteady and generally turbulent. Considering flapping flight in an unsteady wind environment with a periodically varying lateral velocity component, we show that body rotations experienced by flapping wing fliers result in the ...

arXiv, 2004 We give an explanation for the onset of wind-induced flutter in a flag. Our theory accounts for the various physical mechanisms at work: the finite length and the small but finite bending stiffness of the flag, the unsteadiness of the flow, the added mass effect and vortex shedding from the trailing edge.

A Fully Discrete Adjoint Method for Optimization of Flow Problems on Deforming Domains with Time-Periodicity Constraints [PDF]
, 2015 A variety of shooting methods for computing fully discrete time-periodic solutions of partial differential equations, including Newton-Krylov and optimization-based methods, are discussed and used to determine the periodic, compressible, viscous flow around a 2D flapping airfoil.

The mucosal released‐coronally advanced flap: A novel surgical approach—A case report
Clinical Advances in Periodontics, EarlyView.Abstract Background The coronally advanced flap (CAF) can be a predictable surgical technique for the treatment of gingival recessions. However, the characteristics of the defect (e.g., limited amount of keratinized gingiva or flap tension, etc.) may limit the use of the CAF with a possible requirement of additional surgical interventions (i.e., the ...

Growth and shrinkage of tissue sheets on substrates: buds, buckles, and pores [PDF]
New J. Phys. 26, 103027 (2024)Many tissues take the form of thin sheets, being only a single cell thick, but millions of cells wide. These tissue sheets can bend and buckle in the third dimension. In this work, we investigated the growth and shrinkage of suspended and supported tissue sheets using particle-based simulations.

The wingspan suspension approach: A modified semilunar technique for multiple areas of recession
Clinical Advances in Periodontics, EarlyView.Abstract Background Gingival recession can be considered an undesirable condition that results in the exposure of the root surface. There are many techniques that can be employed to address gingival recession; however, they frequently involve a second surgical site.

Clinical Advances in Periodontics, EarlyView.Abstract Background This study presents the diagnois, management, and tissue response to an acute periodontal lesion with deep pocketing affecting a maxillary central incisor in a young patient devoid of caries or a history of periodontitis. Methods Clinical and radiographic examinations facilitated the diagnosis of the pathology as an endoperiodontal ...
