We present a comparatively simple way to construct MartinLöf random and rec-random sets with certain additional properties, which works by diagonalizing against appropriate martingales. Reviewing the result of Gács and Kučera, for any given set X we construct a Martin-Löf random set from which X can be decoded effectively. By a variant of the basic construction we obtain a rec-random set that i...

Plasmids that share homology with the Haemophilus influenzae chromosome transform wild-type cells more efficiently than they transform recombination-defective mutants. A 5.2-kilobase-pair chromosomal fragment containing the strA gene of H. influenzae was found to promote efficient plasmid establishment in recombination-defective mutants. A cis-acting element in the insert, called rpe for rec-le...

This article examines the permissions and approvals required for nurses and other health professionals to conduct research in the NHS in the U.K. today. A fictitious example of a research study conducted by a nurse who did not obtain NHS research ethics committee (REC) approval is provided. The current position regarding the REC approval process, including the role of ethics in research governa...

P SY CHOSTIMU LANTS, par ticu larly ampheta mine, be came avail able in Amer ica for clini cal use in 1937, and since then have been widely prescribed. More re cently, their bene fi cial ef fects have been over shad owed by the rec og ni tion of a sig nifi cant abuse po ten tial. Nev er the less, the mili tary serv ices, par ticu larly the Air Force, have rec og nized the value of psy chostimu ...

We analyze how to realize Rec. 2020 wide color gamut with quantum dots. For photoluminescence, our simulation indicates that we are able to achieve over 97% of the Rec. 2020 standard with quantum dots by optimizing the emission spectra and redesigning the color filters. For electroluminescence, by optimizing the emission spectra of quantum dots is adequate to render over 97% of the Rec. 2020 st...

NIOSH/NCI (National Institute of Occupational Safety and Health and National Cancer Institute) developed exposure estimates for respirable elemental carbon (REC) as a surrogate for exposure to diesel exhaust (DE) for different jobs in eight underground mines by year beginning in the 1940s-1960s when diesel equipment was first introduced into these mines. These estimates played a key role in sub...

Although tally sets are generally considered to be weak when used as oracles, it is shown here that in relativizing certain complexity classes, they are in fact no less powerful than any other class of sets and are more powerful than the class of recursive sets. More speciically, relativizations of the classes of P-printable sets and sets with small Generalized Kolmogorov complexity (SGK) are s...

The success of active cancer immunotherapy entails a robust induction of tumor-reactive effector and memory CD8+ T cells. We compared the in vivo immunogenicity of the melanoma-associated antigen Melan-A(26-35) encoded by third-generation recombinant lentivector (rec. lv) or as peptide admixed with a strong adjuvant. Ex vivo analyses of immunized HLA-A2/H-2K(b) mice showed that rec. lv triggere...

This study identifies the effects of sleep restriction and subsequent recovery sleep on glucose homeostasis, serum leptin levels, and feelings of subjective satiety. Twenty-three healthy young men were allocated to a control group (CON) or an experimental (EXP) group. After two nights of 8 h in bed (baseline, BL), EXP spent 4 h in bed for five days (sleep restriction, SR), followed by two night...

In this study, the effect of metabolic inhibition (MI) by glucose substitution with 2-deoxyglucose (2-DOG) and/or application of antimycin A on ovine rumen epithelial cells (REC) vacuolar-type H(+)-ATPase (vH(+)-ATPase) activity was investigated. Using fluorescent spectroscopy, basal pH(i) of REC was measured to be 7.3 +/- 0.1 in HCO(3) (-)-free, glucose-containing NaCl medium. MI induced a str...
