Golay Complementary Waveforms in Reed-Müller Sequences for Radar Detection of Nonzero Doppler Targets.

Golay complementary waveforms can, in theory, yield radar returns of high range resolution with essentially zero sidelobes. In practice, when deployed conventionally, while high signal-to-noise ratios can be achieved for static target detection, significant range sidelobes are generated by target returns of nonzero Doppler causing unreliable detection. We consider signal processing techniques using Golay complementary waveforms to improve radar detection performance in scenarios involving multiple nonzero Doppler targets.

HIV Prevention and Rehabilitation Models for Women Who Inject Drugs in Russia and Ukraine.

Women who inject drugs require gender-specific approaches to drug rehabilitation, modification of risk behaviors, and psychosocial adaptation. Improved outcomes have been demonstrated when the specific needs of women's subpopulations have been addressed. Special services for women include prenatal care, child care, women-only programs, supplemental workshops on women-focused topics, mental health services, and comprehensive programs that include several of the above components.

[Anemia and gastroesophageal reflux disease in patients with coronary heart disease].

We studied the relationship between anemia and chronic diseases of the upper gastrointestinal tract in patients with CHD. Patients with CHD and gastroesophageal reflux disease (GERD) had the lowest hemoglobin levels and erythrocyte counts in the absence of pronounced independent effect of GERD. This finding suggests common pathogenesis of CHD, GERD and anemia in patients with coronary problems.
