Is Video Analytics a Game Changer for Market Research ?

Intelligent video analytics (IVA) has been growing in the past decade, with a variety of applications from fraud detection to traffic control. This research focuses on the impact of IVA as a decision support tool for market surveys. We compiled a comparative list of existing market survey methods, and identified potential cognitive biases that these methods may impose. In order to look at the efficiencies and accuracies that can be gained by IVA, we conducted experiments and analyzed the results that are automatically captured by the software in real time. Our results show some unexpected variations that may not be obvious to a market researcher. We conclude that the use of IVA can enhance decision-making by improving response rate and accuracy, and reduce some of the cognitive biases that may be affecting quantitative primary data. However, even though it can identify age, gender, location and time of target audience, with its current capabilities IVA cannot be a substitute for qualitative survey methods.
Monoclonal antibodies to mouse MHC antigens. III. Hybridoma antibodies reacting to antigens of the H-2b haplotype reveal genetic control of isotype expression.

Eleven hybridoma antibodies directed against mouse major histocompatibility complex products of the H-2b haplotype have been produced and characterized. Of 7 antibodies reacting to H-2Kb and/or H-2Db antigens, all cross-reacted with other H-2 antigens, and 5 exhibited no correspondence with a known H-2 specificity established in the H-2 chart. Four anti-Iab antibodies all reacted with antigens encoded by the I-A subregion. Some of these antibodies showed no cross-reaction with other haplotypes, indicating reactions to private specificities of the I-Ab antigen. In addition, these anti-Ia antibodies appeared to be capable of distinguishing fine determinant differences, which corresponding alloantisera failed to reveal. A high frequency of hybridomas secreting IgM antibodies was found after fusions of spleen cells obtained from C3H anti-C3H.SW immunized mice, in contrast to the dominance of IgG hybridomas produced previously by fusions of spleen cells from mice immunized in the reverse direction. An isotype analysis of conventional cytotoxic alloantisera from the same strain combinations was therefore performed. The same correlation with respect to isotype expression was found, indicating that hybridoma antibodies reflect normal antibody responses and suggesting H-2-linked control of this expression.
Canadian tourist and Dominican Republic sex workers.

The Dominican Republic is a popular tourist destination for Canadians. The country's sex industry for tourists developed markedly in the 1980s. The Puerto Plata/Sosua area is currently one of the most popular tourist sites and claimed the highest incidence of AIDS in 1989 at 23.2 cases/100,000 people. Two pilot phases of the Dominican Sex Workers and Canadian Tourists Study have been conducted to obtain methodological and empirical data to use in developing a major study of sex and tourism. First phase interviews were held only with beachboys who make money by having relations with female tourists, while phase two interviews were held with beachboys, female sex workers, and female and male tourists. Results indicate that female tourists consider their relations with male sex workers to be primarily social, while male tourists see their relations with female sex workers as more casual, sexual, and monetarily based. Further, women are more likely than men to continue their relationships with sex workers after returning to Canada; many help their men to immigrate and some get married. To learn more about the dynamics of tourism, sex, and AIDS prevention, the author proposes individual studies exploring the characteristics of each of the following four populations: male and female sex workers and male and female tourists.
How can social planners prevent disappointment in an election?

Mechanism design is concerned with settings where a policy maker (or social planner) faces the problem of aggregating the announced preferences of multiple agents into a collective (or social), system-wide decision. One of the most important ways for aggregation preference used in a multi agent system is using election. In an election, the aim is to select the candidate who reects the common will of the whole society. Despite the importance of this subject, in the real world situations, sometimes under special circumstances, the result of the election is completely an antithesis of the purpose of those who execute it or the election leads to the dissatisfaction of a large amount of people. For analyzing these situations, a notion is discussed in the present paper called social disappointment and then new protocols are proposed to prevent social disappointment. A version of the impossibility theorem is stated and proved regarding social disappointment in elections. In the end, the numerical results obtained by simulating the voting protocols of plurality and Hare system are given, to show that Hare system is a little more seccessful than plurality to prevent social disappointment.
Integrated Compact Microstrip Filters for 60 GHz Applications

An integrated microstrip filter for 60 GHz applications with image suppression of 24 dB and insertion loss of 11 dB was designed and measured. This is the first integrated filter for 60 GHz applications. Filter dimensions are 0.24 mm2. An optimized compact integrated filter for IEEE 802.15. 3c standard with insertion loss of 5 dB and image rejection of 30 dB was designed. We suggest optimization technique to reduce insertion loss of integrated filters. A compact, robust microstrip filter for 60 GHz applications on a PCB board, produced in an inexpensive technological process is presented.
Identification and Characterization of a Novel Protein (p137) Which Transcytoses Bidirectionally in Caco-2 Cells (*)

Antisera raised against detergent-extracted membrane fractions from the human intestinal epithelial cell line Caco-2 were used to screen a human colon cDNA library in a bacteriophage expression vector. This led to the identification, molecular cloning, and sequencing of a novel plasma membrane protein (p137) which was present in approximately equal amounts on the basolateral and apical surfaces of the cell. The pattern of extraction of p137 from membranes by Triton X-114 and its release from membranes after incubation with phosphatidylinositol-specific phospholipase C were consistent with it being a glycosylphosphatidylinositol-anchored membrane protein. Using antibodies raised against bacterial fusion proteins, it was shown that p137 was present on the cell surface as a reducible homodimer of 137 kDa subunits. There was constitutive release of p137 into the culture medium as a non-reducible 280-kDa entity. Pulse-chase experiments showed that newly synthesized p137 appeared at the basolateral side of a Caco-2 cell layer before appearing at the apical domain. Domain-specific surface biotinylation of Caco-2 cells at 4°C, followed by chasing at 37°C, demonstrated that p137 is capable of transcytosing in both directions across Caco-2 cells. The unusual plasma membrane domain distribution of this glycosylphosphatidylinositol-linked protein and its transcytosis characteristics demonstrate the existence of a previously uncharacterized apical to basolateral transcytotic pathway in Caco-2 cells.
Hepatitis B Markers in United States Drug Addicts with Special Emphasis on the Delta Hepatitis Virus

Hepatitis B virus and hepatitis delta virus co‐infection in drug addicts has been well described in Europe, the latter agent appearing to have been introduced there in the mid‐1970's. Currently, similar data are scanty among United States addicts. We therefore reevaluated 99 drug addicts from three different geographic locations in the United States who had participated in a Veterans Administration Cooperative Study between 1972 and 1975. Almost all were asymptomatic, and all had been subjected to liver biopsy because of prolonged aminotransferase abnormalities. Stored sera were tested for antibody to hepatitis delta antigen (anti‐HD) by radioimmunoassay and available liver biopsies examined for hepatitis delta antigen (HDAg) by immunofluorescence.
National guidelines for the management of absolute cardiovascular disease risk

TO THE EDITOR: The study by Rickwood and colleagues1 of aggregated national data for young people attending headspace centres is most welcome, as we can now compare headspace with other pre-existing and current datasets. In 2001, we reported on mental health services provided during 46 515 consultations by 386 general practitioners (mean patient age, 46 years; 34% male). 2 At the time, we noted that being aged under 25 years was associated with unmet need for both threshold (odds ratio, 1.34) and subthreshold mental disorders (odds ratio, 1.94–2.11). 3 We concluded that young people with mental disorders were particularly poorly served by general practice.4 While these data informed subsequent development of youth-specifi c services, we did not specifi cally report data for people aged under 25 years. Of these participants, 3503/5868 self-reported a signifi cant mental health problem. Consequently, we can compare directly our 2001 cohort2,3 with that of the new aggregated headspace cohort.1 At this stage, it would appear that only small differences are evident (2001 v 2013, respectively: male, 27% v 36%; born overseas, 12% v 7%; Aboriginal and Torres Strait Islander descent, 5% v 8%; living in major cities, 65% v 57%; non-participation in employment or education, 36% v 29%; and no days out of role, 41% v 36%). In a dataset collected between 2007 and 2009 from two urban headspace sites managed by the University of Sydney, we noted a more substantial engagement of young men (of 1260 participants, 53% were male) and comparable disability characteristics to the two other datasets (non-participation in employment or education, 30%; no days out of role, 34%). 5 In future reports from headspace nationally and locally, we look forward to presentation of other data that permit relevant comparative assessment and challenge us to design new services to meet known gaps.
An integrated indicator system for patent portfolios: evidence from the telecommunication manufacturing industry

ABSTRACT Against the background of ‘patent portfolio races’ in industries such as telecommunications, this paper proposes a set of patent portfolio indicators to measure patents’ scale and diversity. This indicator system is used in a time series to analyse the patenting activity and technology strategy of the world’s top 20 firms in the telecommunication manufacturing industry, based on a large data set from United States Patent and Trade Office. In combination with composite and relative measures, we identify the firms’ comparative positions in patenting activity. The paper adds to the ongoing discussion about, and enriches the theory of, patent portfolios.
Tumoristatic effects of endostatin in prostate cancer is dependent on androgen receptor status

Although anti‐angiogenic therapy is a promising new line of therapy for prostate cancer, we recently reported that stable expression of endostatin arrested the progression of prostate cancer to poorly differentiated state and distant metastasis in TRAMP mice. However, the same therapy failed to provide any benefit when given either during or after the onset of metastatic switch. The present study determined the possible mechanisms behind the selective advantage of endostatin therapy in early‐stage disease.
Synchronous and sequential activation of latently infected Epstein-Barr virus genomes

A lymphoid cell system was established that can induce the prompt and synchronous activation of latent Epstein-Barr virus (EBV) genomes and thus allows the identification of viral genes that are activated sequentially depending on their functions. With this system, we proved that disruption of EBV latency is initiated by activation of four EBV genes and that protein synthesis is not required prior to activation of latent EBV. The system should be an in vitro model for studying the mechanism of herpesvirus latency.
Remote acoustic powering and data transmission for sensors inside of conductive envelopes

In modern aeronautics and aerospace industry there is a great demand for wireless sensors in order to improve efficiency, reliability and to reduce the costs. They are the key enablers for improved system concepts like e.g. condition based maintenance. In some cases, sensors need to be placed in closed conductive envelopes like hydraulic accumulators, oxygen bottles, etc., where battery usage may be not allowed or not possible due to maintenance requirements and where classical wireless radio frequency communication is not applicable due to strong shielding effects. For this field of applications, a solution has been developed that uses ultrasonic acoustic waves for a wireless transmission of energy and data through the envelope walls. The main benefit of this technology is that the envelope remains unaffected and therefore the hermeticity and structural integrity are retained. Moreover the sensor can be chosen almost independently from the communication and power transmission system.
A semimechanistic model of the time‐course of release of PTH into plasma following administration of the calcilytic JTT‐305/MK‐5442 in humans

JTT‐305/MK‐5442 is a calcium‐sensing receptor (CaSR) allosteric antagonist being investigated for the treatment of osteoporosis. JTT‐305/MK‐5442 binds to CaSRs, thus preventing receptor activation by Ca2+. In the parathyroid gland, this results in the release of parathyroid hormone (PTH). Sharp spikes in PTH secretion followed by rapid returns to baseline are associated with bone formation, whereas sustained elevation in PTH is associated with bone resorption. We have developed a semimechanistic, nonpopulation model of the time‐course relationship between JTT‐305/MK‐5442 and whole plasma PTH concentrations to describe both the secretion of PTH and the kinetics of its return to baseline levels. We obtained mean concentration data for JTT‐305/MK‐5442 and whole PTH from a multiple dose study in U.S. postmenopausal women at doses of 5, 10, 15, and 20 mg. We hypothesized that PTH is released from two separate sources: a reservoir that is released rapidly (within minutes) in response to reduction in Ca2+ binding, and a second source released more slowly following hours of reduced Ca2+ binding. We modeled the release rates of these reservoirs as maximum pharmacologic effect (Emax) functions of JTT‐305/MK‐5442 concentration. Our model describes both the dose‐dependence of PTH time of occurrence for maximum drug concentration (Tmax) and maximum concentration of drug (Cmax), and the extent and duration of the observed nonmonotonic return of PTH to baseline levels following JTT‐305/MK‐5442 administration.
Linear discriminant models for unbalanced longitudinal data.

This paper discusses statistical methods for the classification of observations into one of two or more groups based on longitudinal observations. Measurements on subjects in longitudinal medical studies are often collected at different times and on a different number of occasions. Classical multivariate methods for linear discriminant analysis are difficult to apply to repeated measurements due to the highly unbalanced structure observed in these data. Linear models for the analysis of longitudinal data proposed by Laird and Ware and non-linear models proposed by Lindstrom and Bates can be used to estimate population parameters for a discriminant model that classifies individuals into distinct predefined groups or populations. An example is presented using data from a study in 150 pregnant women in Santiago, Chile, in order to predict normal versus abnormal pregnancy outcomes.
T-Type Ca2+ Channel Inhibition Induces p53-Dependent Cell Growth Arrest and Apoptosis through Activation of p38-MAPK in Colon Cancer Cells

Epithelial tumor cells express T-type Ca2+ channels, which are thought to promote cell proliferation. This study investigated the cellular response to T-type Ca2+ channel inhibition either by small-molecule antagonists or by RNAi-mediated knockdown. Selective T-type Ca2+ channel antagonists caused growth inhibition and apoptosis more effectively in HCT116 cells expressing wild-type p53 (p53wt), than in HCT116 mutant p53−/− cells. These antagonists increased p53-dependent gene expression and increased genomic occupancy of p53 at specific target sequences. The knockdown of a single T-type Ca2+ channel subunit (CACNA1G) reduced cell growth and induced caspase-3/7 activation in HCT116 p53wt cells as compared with HCT116 mutant p53−/− cells. Moreover, CaCo2 cells that do not express functional p53 were made more sensitive to CACNA1G knockdown when p53wt was stably expressed. Upon T-type Ca2+ channel inhibition, p38-MAPK promoted phosphorylation at Ser392 of p53wt. Cells treated with the inhibitor SB203580 or specific RNAi targeting p38-MAPKα/β (MAPK14/MAPK11) showed resistance to T-type Ca2+ channel inhibition. Finally, the decreased sensitivity to channel inhibition was associated with decreased accumulation of p53 and decreased expression of p53 target genes, p21Cip1 (CDKN1A) and BCL2-binding component 3 (BBC3/PUMA). Implications: A novel pathway involving p53 and p38-MAPK is revealed and provides a rationale for antitumor therapies that target T-type Ca2+ channels. Mol Cancer Res; 12(3); 348–58. ©2013 AACR.

Faces change over time and this has been problematic for face biometric systems. Little research has been conducted in this area and this study reviews two face biometric systems, Neurotechnology’s Verilook and Luxand’s FaceSDK, and conducts experiments with the affects of aging in mind. Research was conducted on how anthropometrics is linked to facial biometric systems and the orbital areas of 13 candidates were analyzed. An extensive literature review of past and present face biometric applications was conducted and facial recognition software for laptops were reviewed for mobile user authentication.
Defense Technical Information Center Compilation Part Notice ADP 015074

Channel recessed 4H-SiC MESFETs have demonstrated excellent small signal characteristics and the effect of Si3N4 passivation on these devices has been studied in this work. A saturated current of 250270 mA/mm and a maximum transconductance of 40-45 mS/mm were measured for these devices. The 3-terminal breakdown voltage V&s ranges from 120 V to more than 150 V, depending on gatedrain spacing. 2 x 200 pm devices with 0.45 pm gate length show high F, of 14.5 GHz and Fm. of 40 GHz. After Si3N4 passivation, the output power and PAE were increased by 40% and 16%, respectively, for CW power measurement. Other measurements, such as, the change in surface potential and the dispersion of the drain current make it clear that the passivation of SiC MESFETs reduces the surface effects and enhances the RF power performance by suppressing the instability in DC characteristics. L Introduction SiC MESFETs have emerged as promising high power microwave devices due to unique material properties, such as, high saturated electron velocity, high breakdown field, and high thermal conductivity. Wide bandgap semiconductor devices, such as, GaN HEMTs and SiC MESFETs have been developed for high power applications and have shown great potentials in comparison to GaAs and other commercially available devices. SiC MESFETs show better linearity than GaN HEMTs but operate at lower frequencies. In this work, channel recessed 4H-SiC MESFETs were fabricated and they have demonstrated excellent small signal characteristics, such as, Ft of 14.5GHz and Fm,, of 40GHz. The device performance was compared to the case without channel recess that has also been fabricated on the same material. The improvement in small signal characteristics can be explained by a decrease in feedback capacitance and higher aspect ratio (L/a) that can enhance channel modulation and increase the ratio of Gm,/Go. SiC MESFETs have been reported to have current instability and strong dispersion [1]. We present the effect of Si3N4 passivation on 4H-SiC MESFETs by measuring the instability of DC drain current, the dispersion of drain current with input power, the change in surface potential, etc. The Si3N4 passivation reduced surface trapping effect and enhanced the power performance. From our measurements, however, we found out that both the surface trapping and deep traps in the substrate can be responsible for the instability in SiC MESFETs. 0-7803-7478/02/$17.00 © 2002 IEEE 75
IMMEDIATE EFFECT OF ACTIVE RELEASE TECHNIQUE VERSUS MULLIGAN BENT LEG RAISE IN SUBJECTS WITH HAMSTRING TIGHTNESS: A RANDOMIZED CLINICAL TRIAL

Background: To study and compare the effectiveness of active release technique and mulligan bent leg raise in subjects with hamstring tightness. Methods: 40 normal healthy subjects (20 in each group) were recruited in the study under simple randomization method. Group A received single session of Active Release Technique and Group B received single session of Mulligan Bent Leg Raise technique for hamstring tightness. Popliteal angle and Sit and reach flexibility tests were measured pre intervention and post intervention. Data was analyzed using t-test. Results: The group treated with Active release technique showed significant improvement in Popliteal angle (P<0.001) and sit and reach flexibility test (P<0.001) as compared to Mulligan bent leg raise technique. Results showed the significance difference within the groups post intervention. Conclusion: A single session of Active release technique is better as compared to Mulligan bent leg raise technique to improve hamstring flexibility and range of motion.
Design and Implementation of a Hybrid Recommender System for Predicting College Admission

This paper presents a new college admission system using hybrid recommender based on data mining techniques and knowledge discovery rules, for tackling college admissions prediction problems. This is due to the huge numbers of students required to attend university colleges every year. The proposed system consists of two cascaded hybrid recommenders working together with the help of college predictor, for achieving high performance. The first recommender assigns student’s tracks for preparatory year students. While the second recommender assigns the specialized college for students who passed the preparatory year exams successfully. The college predictor algorithm uses historical colleges GPA students admission data for predicting most probable colleges. The system analyzes student academic merits, background, student records, and the college admission criteria. Then, it predicts the likelihood university college that a student may enter. A design for prototype system is implemented and tested with live data available in the On Demand University Services (ODUS-Plus) database resources, at King Abdulaziz University (KAU). In addition to the high prediction accuracy rate, flexibility is an advantage, as the system can predict suitable colleges that match the students’ profiles and the suitable track channels through which the students are advised to enter. The system is adaptive, since it can be tuned up with other decision makers attributes performing trusted needed tasks faster and fairly.
