Planning and Moving in Dynamic Environments - A Statistical Machine Learning Approach. (2009)

Vijayakumar, S, Toussaint, M, Petkos, G, Howard, M

In this chapter, we develop a new view on problems of move- ment control and planning from a Machine Learning perspective. In this view, decision making, control, and planning are all considered as...

Learning Robot Dynamics for Computed Torque Control Using Local Gaussian Processes Regression (2008)

Nguyen-Tuong, D., Peters, J., Stoica, A., Tunstel, E., Huntsberger, T., Arslan, T., ...

Accurate models of the robot dynamics allow the design of significantly more precise, energy-efficient and more compliant computed torque control for robots. However, in some cases the accuracy of...

In vitro micropropagation of orchid, Oncidium   sp. (Dancing Dolls) (2007)

Kalimuthu, K., Senthilkumar, R., Vijayakumar, S.

A successful procedure was established for in vitro mass multiplication of orchid (Oncidium sp.). In vitro regeneration multiplication and rooting of plantlets were achieved from the immature seeds...

Biodiversity of Cyanobacteria in industrial effluents (2007)

Vijayakumar, S., Thajuddin, Nooruddin, Manoharan, Chokkaiya

Biodiversity of cyanobacteria in industrial effluents. In order to study the biodiversity of cyanobacteria in industrial effluents, four different effluents such as dye, paper mill, pharmaceutical...

A simple, adaptive locomotion toy-system (2004)

Buchli, J., Ijspeert, A.J., Schaal, S., Ijspeert, A.J., Billard, A., Vijayakumar, S., ...

In order to make the transfer of biological principles to engineering problems successful, it is important to study the fundamental properties of biological systems. The goal is to arrive with useful...

Using humanoid robots to study human behavior (2000)

Atkeson, C.G., Hale, J.G., Pollick, F., Riley, M., Kotosaka, S., Schaul, S., ...

Our understanding of human behavior advances as our humanoid robotics work progresses-and vice versa. This team's work focuses on trajectory formation and planning, learning from demonstration,...

Differential stability of beta-sheets and alpha-helices in beta-lactamase: a high temperature molecular dynamics study of unfolding intermediates.

Vijayakumar, S, Vishveshwara, S, Ravishanker, G, Beveridge, D L

beta-Lactamase, which catalyzes beta-lactam antibiotics, is prototypical of large alpha/beta proteins with a scaffolding formed by strong noncovalent interactions. Experimentally, the enzyme is well...

The Effect of Apical and Basolateral Lipids on the Function of the Band 3 Anion Exchange Protein

Hof, Wouter Van't, Malik, Abha, Vijayakumar, S., Qiao, Jizeng, Adelsberg, Janet Van, Al-Awqati, Qais

Although many polarized proteins are sorted to the same membrane domain in all epithelial tissues, there are some that exhibit a cell type–specific polarity. We recently found that band 3 (the...

Hensin Remodels the Apical Cytoskeleton and Induces Columnarization of Intercalated Epithelial Cells: Processes that Resemble Terminal Differentiation

Vijayakumar, S., Takito, Jiro, Hikita, Chinami, Al-Awqati, Qais

Intercalated epithelial cells exist in a spectrum of phenotypes; at one extreme, β cells secrete HCO3 by an apical Cl/HCO3 exchanger and a basolateral H+ ATPase. When an immortalized β cell line is...

African-American heredity prostate cancer study: a model for genetic research.

Powell, I. J., Carpten, J., Dunston, G., Kittles, R., Bennett, J., Hoke, G., ...

A genome-wide scan of high-risk prostate cancer families in North America has demonstrated linkage of a particular marker to Chromosome 1q (HPC1). An even greater proportion of African-American...

Results of a study to correlate serum prostate specific antigen and reproductive hormone levels in patients with localized prostate cancer.

Vijayakumar, S., Quadri, S. F., Dong, L., Ignacio, L., Kathuria, I. N., Sutton, H., ...

This cross-sectional study was undertaken to determine whether serum hormones (free testosterone, androstenedione, luteinizing hormone, or prolactin) have any influence on serum prostate specific...

Prostate-specific antigen and androgens in African-American and white normal subjects and prostate cancer patients.

Asbell, S. O., Raimane, K. C., Montesano, A. T., Zeitzer, K. L., Asbell, M. D., Vijayakumar, S.

Prostate cancer in African Americans is more aggressive and common than in any other racial group. An endocrine mechanism has been proposed to account for this racial difference. However, androgen...

Role of Radiation Therapy in Small Cell Lung Cancer: A Bio-Clinico-Pathological Review and Perspective

Vijayakumar, S., Shepard, K., Thomas, F., Weick, J., Rice, T., Mehta, A.

The role of radiotherapy in small cell carcinoma of the lung is unsettled; however, the radiosensitivity of this neoplasm is unquestioned. The ability of radiotherapy to cure or improve patients with...

Less well known parameters of in vitro radiosensitivity.

Vijayakumar, S., Ng, T. C., Koumoundouros, I., Higgins, P. D., Thomas, F. J.

In addition to well known parameters used for measuring in vitro cellular radiosensitivity (mean lethal dose, extrapolation number, quasithreshold dose), there are other, less well known measures...
