background: celiac disease is one of the malabsorption syndromes leads to growth and development retardation in children. there is no test lonely can definitely diagnose celiac; however, the collection of clinical findings, serologic tests, intestinal biopsy, and response to treatment may diagnose it. although diagnostic value is variable in different studies, they are used a non-invasive and a...

AIM To provide simple tests that would help in the identification of corynebacteria that produce diphtheria toxin. METHODS A collection of 99 freshly isolated corynebacteria was assembled and the cultures identified by conventional tests confirmed by an identification kit. Modifications were made to procedures for preparation of the culture medium for the Elek test and to the test for detecti...

OBJECTIVE To compare brief dementia screening tests as candidates for routine use in primary care practice. METHOD We selected screening tests that met 2 criteria: 1) administration time of 10 minutes or less in studies including individuals with, and without, dementia; and 2) performance characteristics evaluated in at least 1 community or clinical sample of older adults.

This paper focusses on “safe” screening techniques for the LASSO problem. Motivated by the need for low-complexity algorithms, we propose a new approach, dubbed “joint screening test”, allowing to screen a set of atoms by carrying out one single test. The approach is particularized to two different sets of atoms, respectively expressed as sphere and dome regions. After presenting the mathematic...
