On the embeddability of certain infinitely divisible probability measures on Lie groups

We describe certain sufficient conditions for an infinitely divisible probability measure on a class of connected Lie groups to be embeddable in a continuous one-parameter convolution semigroup of probability measures. (Theorem 1.3). This enables us in particular to conclude the embeddability of all infinitely divisible probability measures on certain Lie groups, including the so called Walnut group (Corollary 1.5). The embeddability is concluded also under certain other conditions (Corollary 1.4 and Theorem 1.6).Comment: 24 page

Circles of Exclusion: The Politics of Health Care in Israel

Dr. Dani Filc delves into Israel\u27s health care system and provides numerous insights on how a private health care system undermines the principle of caring for the poor. Dr. Filc stresses that blind commitment to a for-profit health care system leads to wasted money and increased social inequity

Separation of Blood Mixtures Using Fluorescently Labeled Antibodies

Identifying and analyzing biological mixture samples at a crime scene are of paramount concern for forensic scientists, especially if that type of evidence contains only one cell type. The presence of multiple contributors in a biological evidence sample reduces the probative value of DNA evidence and can sometimes lead to its eventual loss of value. As such, this study was performed in an attempt to examine and evaluate flow cytometry analysis as a means to separate blood mixture samples labeled with fluorescent antibodies. Fluorescein Isothiocyanate (FITC) antibodies were specifically targeted and bound to HLA (Human Leukocyte Antigens) markers present on nucleated cells in the blood, after which they were isolated from the blood mixture utilizing Fluorescent Activated Cell Sorting (FACS) - A high throughput technique that separates cell populations based on their optical activity, followed by STR analysis. This approach was tested on fresh blood mixtures containing two contributors, where one contributor possessed an HLA A*02 allele that was not shared with the other contributor. We hypothesize that HLA A*02 positive samples would exhibit fluorescence when bound with the fluorescently labeled antibodies while the HLA A*02 samples would not. As such, we would be able to separate both cell populations using FACS followed by STR analysis. Such a work flow is believed to yield discriminant STR profiles unique to each contributor thus increasing the probative value of the evidence at hand. Results supported our hypothesis and yielded discriminant STR profiles for both contributors, with minor peaks from the A*02 negative contributor being observed in A*02 positive contributor sample. We can then conclude that HLA-A*02 antibodies coupled to FACS is a suitable method that can be utilized to evaluate and separate blood mixture samples in an attempt to yield discriminant STR profiles.https://scholarscompass.vcu.edu/uresposters/1265/thumbnail.jp

Does New Zealand visitors follow the Joseph Effect? Some empirical evidence

The report departs from conventional time series analysis and investigates the existence of long memory (LRD) in the stream of daily visitors, arriving from various sources to New Zealand from 1997 to 2010, using selected estimators of the Hurst-exponent. The daily arrivals of visitors are treated as a stream of "digital signals" with the inherent noise. After minimizing the noise (i.e. the presence of short-term trends, periodicities, and cycles) we found the existence of significant long memory embedded in our data of daily visitors from all sources and in the aggregate. Strong evidence of embedded “long memory” implies that Joseph Effect – that good times beget good times and bad times beget bad – whose existence in the underlying process may have interesting implications for tourism policy makers. Our findings suggest evidence of such long term memory in tourist arrival data. Further, unless this long memory effect is taken into consideration, any traditional statistical analysis based on Gaussian and Poisson assumptions may be overly biased

The asymptotic density of finite-order elements in virtually nilpotent groups

Let G be a finitely generated group with a given word metric. The asymptotic density of elements in G that have a particular property P is defined to be the limit, as r goes to infinity, of the proportion of elements in the ball of radius r which have the property P. We obtain a formula to compute the asymptotic density of finite-order elements in any virtually nilpotent group. Further, we show that the spectrum of numbers that occur as such asymptotic densities consists of exactly the rational numbers in [0,1).Comment: 26 page

EFFECTIVENESS OF USING VIDEO IN THE LEARNING OF COMPUTER HARDWARE ASSEMBLING CLASS XII INDUSTRIAL ELECTRONICS IN SMK NEGERI 2 WONOSARI

This study aims to determine the effectiveness of video in the learning materials and computer hardware assembling to know the difference student learning outcomes before and after using video in class XII Industrial Electronics SMKN 2 Wonosari. This research was conducted in November 2010 until December 2010. Type research is kind of population research because the sample size research take the entire population of the entire class XII students of Industrial Electronics, this population is 35 students. Research’s method is Pre-Experimental Designs and using One-Group Pretest-Posttest Design. This method aims to determine the effect of a treatment in the learning process. The media used is a CD video tutorial "Merakit Komputer Untuk Orang Awam." Data collection techniques used in this research using a pretest and posttest. Validation of research instruments is through expert opinions (judgments) and then tested through a pretest on students majoring in Industrial Electronics XII SMK N 2 Wonosari. Data analysis techniques used to analyze the research data is to be tested in SPSS 17 for Windows. Based on a research known to increase learning outcomes after a given treatment using video CD Tutorial is from 63.97 (mean pretest) to 76.37 (mean posttest). Results mastery learning after using video media tutorial CD reaches 71.42% which means that these results exceeded the minimum limit of 65% so that concluded video media Tutorial CD " Merakit Komputer Untuk Orang Awam " not yet effective in learning to use the lessons of computer hardware assembling class XII Industrial Electronics SMK Negeri 2 Wonosari.
