OBJECTIVE To investigate: (i) the intra-rater, inter-rater and test-retest reliability of the 12-step stair test; (ii) its correlation with other stroke-specific impairments; and (iii) the cut-off scores that best discriminate patients with stroke from healthy elderly subjects. DESIGN Cross-sectional study. SETTING University-based rehabilitation centre. SUBJECTS Thirty-five subjects with...

An oil droplet wrapped with poly(N-isopropylacrylamide) grafted nanoparticles can ascend or descend in water repeatedly by simply tuning the temperature of water above or below 33 °C, while avoiding the use of sophisticated equipment and complex nanostructures.

In [2, Section 1.6] Peskine and Szpiro prove a theorem on adic approximations of finite free resolutions over local rings which, together with M. Artin's Approximation Theorem [1], allows them to "descend" modules of finite projective dimension over the completions of certain local rings to modules of finite projective dimension over finite etale extensions of those rings. In this note we will ...

Cryptorchidism: When the testes do not descend, the condition is called ‘cryptorchidism’. The condition occurs in about 3% of full-term infants and about 30% of premature infants. Untreated cryptorchidism on both sides results in sterility because the cells involved in the initial development of sperm are destroyed by the higher temperature of the pelvic cavity. The chance of testicular cancer ...

A class of conformally flat and asymptotically anti-de Sitter geometries involving profiles of scalar fields is studied from the point of view of gauged supergravity. The scalars involved in the solutions parameterise the SL(N, IR)/SO(N) submanifold of the full scalar coset of the gauged supergravity, and are described by a symmetric potential with a universal form. These geometries descend via...
