Modern missile seekers invariably employ monopulse radar with phase locked loop (PLL) as a frequency (angle) tracking subsystem in the receiver. The frequency locking and/or unlocking of these receivers can be achieved either by introducing imperfections in the monopulse design or using multiple repeater sources. In the present paper, the break-lock of PLL synthesizer in the monopulse radar rec...

This paper investigates the interaction effects of motion filter order and break frequency on pilots’ manual control behavior performance using two simulators. Eighteen pilots performed...

PURPOSE To identify the gene disrupted by a de novo reciprocal balanced translocation t(6;8)(q26;q13) in a patient with Duane retraction syndrome (DURS). The break point in chromosome arm 8q is positioned within the DURS1 critical region. METHODS Fluorescence in situ hybridization (FISH) analysis using cosmid and BAC clones covering the DURS1 locus was performed to define the break point posi...

The RecE recombination pathway is active in Escherichia coli recB recC sbcA mutants. To isolate and characterize products and intermediates of RecE-mediated, break-induced, intramolecular recombination, we infected recB recC sbcA mutants, expressing EcoRI endonuclease, with chimeric lambda phages that allow EcoRI-mediated release of cloned linear recombination substrates. Substrates with direct...

We report a break for a recently proposed class of cryptosystems. The cryptosystem uses constant points of a periodic secret orbit to encrypt the plaintext. In order to break the system, it suffices to sort the constant points and find the initial fixed point. We also report breaks for the modified versions of the cryptosystem. Besides, we discuss some efficiency issues of the the cryptosystem.

a strategy that integrates an organization's marketing goals into a cohesive whole, ideally drawn from market research, focuses on the ideal product mix in order to achieve maximum profit potential; the marketing strategy is set out as a marketing plan, a good idea, method, information, object, or service that is the end result of a process and serves as a need or want satisfier. it is usually ...

purpose: to evaluate the underlying causes of rhegmatogenous retinal detachment (rrd) in eyes operated for this reasion. methods: out of 1473 patients who underwent retinal detachment surgery, records of 369 patients were randomly selected and evaluated for the types of retinal breaks, the underlying disorders, and location of breaks. results: fifty-two percents of patients were less than 50 ye...

Research has not systematically assessed and validated preferences for staff in adults with developmental disabilities. Three adults with developmental disabilities (aged 32 to 43 years) identified preferred and nonpreferred staff using verbal and pictorial preference assessments. During break-point analyses with progressive-ratio schedules, all 3 had higher break points when working for positi...
