The Effects of RHAMM on Cell Division, Cell Motility, and Tumorigenesis
… maintains mitotic spindle integrity and impacts directional cell migration through its interactions with microtubule and centrosome structures. The consequences of a mutated leucine zipper on cell division, cell motility, and tumorigenesis were assessed. Although mutant RHAMMΔ163 promoted …

Modeling and trading the Greek stock market with artificial intelligence models
… some new methodologies for the prediction of the directional movement of financial assets with an application to the ASE20 Greek stock index. Specifically, we use some alternative computational methodologies named Evolutionary Support Vector Machine (ESVM), Gene Expression programming, Genetic …

COMPENSATORY HIP AND KNEE MECHANICS IN TRANSTIBIAL AMPUTEES DURING STAIR DESCENT AND DIRECTIONAL TASK
… staircase followed by one of two anticipated directional tasks. Force, kinematics and gait parameters were chosen to compare mechanics and stride characteristics between the residual limb, intact limb and able-bodied dominant limb between a straight walking condition and a non linear …

Phenomenological models of motor proteins
Motor proteins produce directional movement and mechanical output in cells by converting chemical energy into mechanical work. Innovative applications of physics experimental techniques to the study of motor proteins have generated a wealth of data. By careful analysis and modeling of this data, we …

Air-breathing and movement ecology of Arapaima sp. in the Amazon
… for seasonally hypoxic waters and directed movements to best utilize habitats as they become available. This study examined the environmental, temporal and body-size influences on air-breathing behavior and movement ecology of Arapaima sp., one of the most economically and ecologically …

Identity development of Chinese graduate students in the United States : a phenomenological investigation
… multiple dimensions of identity through a bidirectional movement of identity differentiation and integration. The study identified five themes that represent the significant contexts that coexisted in forming an enmeshed developmental environment for Chinese graduate students. These five …

Studies on Lymphokine Activity in the Amphibian Rana Temporaria
… effect in mammals. 1. Activity decreasing random movement of peritoneal cells, Migration inhibition factor or MIF 2. Activity increasing random movement of peritoneal cells, Migration stimulatory factor or MStF 3. Activity increasing glucose uptake by peritoneal cells, Macrophage activating factor …

Error magnitude and directional accuracy for time series forecasting evaluation
… measured in terms of error magnitude. However, directional accuracy is as important as error magnitude especially in economics since it considers directional movement of the data. This research attempted to combine the two types of measurements by introducing a new element, the slope value. This …

Determining Plasmodium falciparum Malaria Transmission Networks Through Sequenom And Capillary Electrophoresis Genotyping
… for parasite genotype clusters, barriers to, and directionality in parasite movement. Parasite genetic relatedness was predicted by relatedness in time and space at micro-geographical scales, but no evidence of population structure was seen over larger areas. No barriers to parasite movement were …

Fog Harvesting: Inspired by Spider Silk
… to further enhance water collecting rate. This directional droplet movement is caused by spindle-knot and joint structure on the biomimetic silk. The spindle-knot is randomly porous, and the joint is stretched porous. In addition, the spindle-knot has a tilted angle β above the joint region. Due …

Pten Function in Postnatal Brain Development and Tumorigenesis
… organisms showing that Pten was required for directional migration, live imaging of acute brain slices showed that the migrating Pten-deficient neuroblasts were not defective in speed and showed appropriate directional movement. Therefore, the apparent "migration defect" in Pten-deficient …

Study and engineering of nucleic acid-binding repeat proteins
… project, a PUF-based system for intracellular directional transport of mRNA was developed in mammalian cells. The biosynthetic device consists of a “motor”, which provides a directional movement, and the PUF protein that dimerizes with the “motor” in a ligand-dependent manner. The system …

Design, Analysis and Testing of a Self-reactive Wave Energy Point Absorber with Mechanical Power Take-off
… MMR mechanism can transfer the reciprocated bi-directional movement of the ocean wave into unidirectional rotation of the generator. As a result, this mechanism brings in two advantages towards the PTO. The first advantage it possess is that the alternating stress of the PTO is changed into …

Design, Validation, and Clinical Testing of a Novel Fastening Device for a Scoliosis Brace
… (≈20N) was used for all tests. Throughout the movement, the reaction forces and strap tensions in the craniocaudal and mediolateral axes were continuously recorded. The results were as follows: The CTU devices provided a greater range of brace gap displacement compared to the Velcro straps. For …
