Using a small near-Earth object (NEO) to impact a larger and potentially threatening NEO has been suggested as an effective method to avert a collision with Earth. This paper develops a procedure for analysis of the technique for specific NEOs. First, an optimization method is used to select a proper small body from the database. Some principles of optimality are achieved with the optimization ...

In Drosophila miranda, a chromosome fusion between the Y chromosome and the autosome corresponding to Muller's element C has created a new sex chromosome system. The chromosome attached to the ancestral Y chromosome is transmitted paternally and hence is not exposed to crossing over. This chromosome, conventionally called the neo-Y, and the homologous neo-X chromosome display many properties of...

Angiotensin converting enzyme inhibitors (ACEIs) are widely used in the treatment of hypertension, myocardial infarction, and congestive heart failure. They have a known adverse effect of unresponsiveness to vasoconstrictors resulting in hypotension for the patients undergoing cardiac surgery. We report a case of a 43-year-old female patient with preoperative lisinopril (2.5 mg per day for a we...

Inferring AS-level end-to-end paths can be a valuable tool for both network operators and researchers. A widely known technique for inferring end-to-end paths is to perform traceroute from sources to destinations. Unfortunately, traceroute requires the access to source machines and is resource consuming. In this paper, we propose two algorithms for AS-level end-to-end path inference. The key id...

2-Deoxystreptamine (2-DOS) aminoglycosides exert their antibiotic actions by binding to the A site of the 16S rRNA and interfering with bacterial protein synthesis. However, the molecular forces that govern the antitranslational activities of aminoglycosides are poorly understood. Here, we describe studies aimed at elucidating these molecular forces. In this connection, we compare the bacterici...

BACKGROUND The rapid identification of acid-fast bacilli recovered from patient specimens as Mycobacterium tuberculosis complex (MTC) is critically important for accurate diagnosis and treatment. A thin-layer immunochromatographic (TLC) assay using anti-MPB64 or anti-MPT64 monoclonal antibodies was developed to discriminate between MTC and non-tuberculosis mycobacteria (NTM). Capilia TB-Neo, wh...
