The activity o f single neurons with constant discharge frequencies in the area around the a-lobe o f the mushroom bodies o f the bee was recorded intracellularly. The spontaneous discharge fre­ quency o f these neurons ranged between 5 and 95 impulses per second. When stimulated, about 80 percent o f the neurons responded to at least one o f five different sensory modalities: scent; light; air...

16 Our previous studies discuss when populations and gradients in allele fre17 quency can persist in the presence of a mean downstream dispersal of propag18 ules from the parents’ location. These studies assume that reproduction is 19 uniform over the lifetime of the adult, and that the larval dispersal kernel 20 is “nearly” Gaussian in shape. These results are extended below to include 21 vari...

Computing frequent itemsets is one of the most prominent problems in data min-ing. We study the following related problem, called FREQSAT, in depth: given someitemset-interval pairs, does there exist a database such that for every pair the fre-quency of the itemset falls into the interval? This problem is shown to be NP-complete. The problem is then further extended to inclu...

When compared to the over-simplified classical skin-effect model, the accurate classical relaxation-effect modelling approach for THz structures at room temperature can be mathematically cumbersome and not insightful. This paper introduces various interrelated electrical engineering concepts as tools for characterizing the intrinsic frequency dispersive nature of normal metals at room temperatu...

A control mechanism that limits nuclear division is pres ent in contact-inhibited nontumorigenic mouse BALB/3T3 cells and mouse embryo fibroblasts. In the absence ofcytoplasmic division, 3T3 and mouse embryo fibroblast cells may undergo nuclear division once or occasionally twice and then stop. Also, there is no increase in the frequency of premature chromosome condensation. In non-contactinhib...

QUENCY. By T. Earl Sullenger, Ph.D., Professor of Sociology in the Municipal University of Omaha. Published New York, John Wiley and Sons, Inc. London, Chapman and Hall. 17/6. Among the scientific and pseudo-scientific works on social subjects that pour in a steady flow from the American press, many seem to have only moderate interest for the English student. Conditions are so different, and th...

due to high speed computer networks, the use of digitally formatted data has increased many folds.the digital data can be duplicated and edited with great ease which has led to a need for effectivecopyright protection tools. digital watermarking is a technology of embedding watermark withintellectual property rights into images, videos, audios and other multimedia data by a certainalgorithm .di...

introduction: recent studies suggest that endocytosis of romk channels is important for regulation of k+ secretion in cortical collecting ducts. in this study the effect of v364d mutation is examined on the membrane turnover and stability of romk2 channel when expressing in xenopus laevis oocytes. materials and methods: in this experimental study, oocytes were isolated by standard protocols usi...

Low-level laser therapy (LLLT) may have utility in the management of side effects radiation head and neck cancer (HNC) patients. Although evidence suggests that LLLT is safe treatment for HNC patients, more research imperative vigilance remains warranted to de-tect any potential adverse on outcomes survival The purpose this study was evaluate effect transcranial low-level irradiation (LLLI) com...
