Intercellular adhesion is assumed to play an important role in a multitude of biological phenomena governing cellular behavior. The rate of intercellular adhesion as a function of the cell cycle traverse has been investigated using, in the monolayer assay, synchronized Chinese Hamster Ovary-K1 cells. Results obtained demonstrate that cells in G1 adhere to G1 cells at twice the rate that S cells...

Introduction: Recent lunar missions provide the planetary science community with vast amounts of new data enabling important insights into the geology and evolution of the Moon on a global scale. Remotely sensed observations of the polar regions reveal the location of persistently illuminated regions and evidence for volatiles captured in cold traps [1-5]. In-situ resource utilization (ISRU) of...

The successful implementation of machine learning in autonomous rover traverse science requires addressing challenges that range from the analytical technical realm, to the fuzzy, philosophical domain of entrenched belief systems within scientists and mission managers. These challenges are many. They include helping scientists understand the benefits and risks of using machine learning onboard ...

Multicellular aggregates of circulating tumor cells (CTC clusters) are potent initiators of distant organ metastasis. However, it is currently assumed that CTC clusters are too large to pass through narrow vessels to reach these organs. Here, we present evidence that challenges this assumption through the use of microfluidic devices designed to mimic human capillary constrictions and CTC cluste...

OBJECTIVE Stents are widely used in coil embolization of intracranial aneurysms, but on occasion, a microcatheter must traverse a stented segment of artery (so-called trans-cell technique) to select an aneurysm, or double stenting may necessary. In such situations, microguidewire passage and microcatheter delivery through a tortuous stented parent artery may pose a technical challenge. Describe...

The expected time for a random walk on an undirected graph G = (V,E) to visit all the vertices is O(|V ||E|) [AKLLR], and is O(|V |) for regular graphs [KLNS]. Here we show that both bounds hold even if we are required to traverse all the edges, although our bound for regular graphs requires that the degree be |V | for some δ < 1.

Intracellular pathogens are microorganisms that traverse the plasma membrane of a particular host cell...

This study investigates optimal parameter setting in abrasive waterjet machining (AWJM) on aluminium alloy AA 6351, using taguchi based Grey Relational Analysis (GRA) is been reported. The water pressure, traverse speed and stand-off-distance were chosen as the process parameters in this study. An L 9 orthogonal matrix array is used for the experimental plan. The performance characteristics whi...

Recently, a ground based laser scanning sensor is receiving more attention as an useful tool for real-time acquisition of 3D data, and its applications are proposed in various fields. For example, a topographic survey for archaeological sites is performed efficiently using a laser scanning sensor. A traverse survey is one of the typical methods for topographic map in archaeological sites. Usual...

Metal matrix composites (MMCs) exhibit improved strength but suffer from low ductility. Metal particles reinforcement can be an alternative to retain the ductility in MMCs (Bauri and Yadav, 2010; Thakur and Gupta, 2007) [1,2]. However, processing such composites by conventional routes is difficult. The data presented here relates to friction stir processing (FSP) that was used to process metal ...
