~ scinating feature of cell locomotion is that net actin polymerization and depolymerization occur simultaneously at different locations in the cytoplasm, while the total concentration of polymerized actin remains roughly constant. Net polymerization occurs primarily at the cell front and net depolymerization occurs, depending on cell type, throughout or at the rear of the lamella (Wang, 1985; ...

Focusing [1] is a proof-theoretic device to structure proof search in the sequent calculus: it provides a normal form to cut-free proofs in which the application of invertible and non-invertible inference rules is structured in two separate and disjoint phases. It is commonly believed that every “reasonable” sequent calculus has a natural focused version. Although stemming from proof-search con...

Model-based diagnosis is based on first-principles reasoning using the behavioral specifications of the primitive components of a device. Unless the computational architecture of the model-based reasoning engine is carefully designed, combinatorial explosion renders the approach useless for devices consisting of more than a handful of components. This paper analyzes the diverse origins of this ...

The external granular layer (EGL) of the cerebellum thickens, thins and disappears in its developmental process. We examined the thickness of the EGL, both intralobule differences and interlobule differences, in the whole midline sections of mouse cerebella for the entire postnatal period up to disappearance. The thinnest site in each lobule was located at the outer apex throughout the observat...

Globalization and transport revolution, logistics integration, and the consequent expansion of port area and hinterland in the maritime industry have redefined the functional role of ports in supply chains and have generated a new pattern of freight distribution. This phenomenon again requires a new approach towards port development and related urban planning. Such changes have inevitably influ...

multipotent mesenchymal stromal cells or mesenchymal stem cells (mscs) are mainly isolated from bone marrow or fat tissue. because of their potential of multilineage differentiation towards bone, cartilage and fat tissue, they were initially evaluated to develop innovative strategies for tissue engineering applications. more recently, they have gained interest based on their immunomodulatory pr...

as one of the most important and fundamental concepts in the divine religions, eternity and immortality after death has always been paid too much attention by religious thinkers mainly muslim scholars and mystics from philosophical, mystical ,theological, and quranic approaches. since mulla sadra's transcendent theosophy is not far from islamic mysticism and even some parts of its general ...

in this paper, we present a capable algorithm for solving a class of nonlinear optimal control problems (ocp's). the approach rest mainly on the differential transform method (dtm) which is one of the approximate methods. the dtm is a powerful and efficient technique for finding solutions of nonlinear equations without the need of a linearization process. utilizing this approach, the optim...

this cross-sectional study aimed to examine the relationship between several dimensions of the burnout syndrome with certain stress-coping strategies, seniority level and marital status in male staff from national police in vaparaíso, chile.the sample collected in 2010 was composed of 338 male officers coming from various special units of a national police in valparaíso. burnout and coping stra...
