Starting from kinetic transport equations and subcellular dynamics we deduce a multiscale model for glioma invasion relying on the go-or-grow dichotomy influence of vasculature, acidity, brain tissue anisotropy. Numerical simulations are performed this with multiple taxis, in order to assess solution behavior under several scenarios taxis growth tumor endothelial cells. An extension incorporate...

Statement of the problem. Due to lack coverage issues describing inter-categorial relations in sphere interaction between taxis and other related semantic categories involved verbalization idea time, this problem is relevant today. The purpose paper describe field integrative inter-connected functional categories: taxis, temporality, aspectuality, temporal localization. Methodology (materials m...

This research involves the study of the existing taxi dispatch system employed by taxi operators in Singapore to handle current bookings. This dispatch system adopts the Global Positioning Systems (GPS), and is based on the nearest-coordinate method, i.e. the taxi assigned for each booking is the one with the shortest, direct, straight-line distance to the customer location. However, the taxi a...

Information processing of the thermoresponse in Escherichia coli was compared with that of the chemoresponse. Competition experiments between various chemical stimuli and the thermal stimulus showed that only L-serine was a potent inhibitor of the thermosensory transduction. The concentration of L-serine necessary for complete inhibition of the thermoresponse was about 0.1 mM. L-Serine at this ...

Campylobacter jejuni constitutes the leading cause of bacterial gastroenteritis in the United States and a major cause of diarrhoea worldwide. Little is known about virulence mechanisms in this organism because of the scarcity of suitable genetic tools. We have developed an efficient system of in vitro transposon mutagenesis using a mariner-based transposon and purified mariner transposase. Thr...

CO SM O S + TA X IS Bruce Caldwell’s observation that “[b]y the 1960s Hayek was seeing complex orders everywhere” is something that struck a cautionary note in our thinking about jazz (Caldwell 2000, p. 19). Indiscriminate use of the concept (known as “concept creep” in the psychology literature) would of course empty it of meaning, a fate that has befallen many a key term in social philosophy....

The world is changing rapidly. Yet a common assumption is that cars, buses and taxis will remain the dominant local passenger transport modes in the coming decades. This concept paper draws on literature sources and on discussions with industry stakeholders to look anew at the local passenger transport sector in the light of broader societal trends to suggest an alternative future, and to offer...

Historically, egg-bound reptile embryos were thought to passively thermoconform to the nest environment. However, recent observations of thermal taxis by embryos of multiple reptile species have led to the widely discussed hypothesis that embryos behaviorally thermoregulate. Because temperature affects development, such thermoregulation could allow embryos to control their fate far more than hi...

In this study, we assessed the development (formation, taxis and settlement) of eukaryotic zoospores under different regimes of exposure to polycyclic aromatic hydrocarbons (PAHs), which imitated environmental scenarios of pollution and bioremediation. With this aim, we used an oomycete, Pythium aphanidermatum, as a source of zoospores and two PAH-degrading bacteria (Mycobacterium gilvum VM552 ...

Current tuberculosis notification rates in South Africa are among the highest ever recorded. Although the human immunodeficiency virus epidemic has been a critical factor, the density of respiratory contacts in highrisk environments may be an important and underappreciated driver. Using a modified Wells-Riley model for airborne disease transmission, we estimated the risk of tuberculosis transmi...
