VEHICLES TRACKING UNDER VARY LIGHTNING CONDITION WITH CORRELATION FILTER FOR INTELLIGENT SURVEILLANCE

With the rapid increase of surveillance cameras leads to security questions. But developing an intelligent video surveillance system needs high computing performance. This paper deals with constructing a video surveillance system that can detect moving vehicles using limited resources. We propose a novel framework to detect and track moving vehicle under complex lighting condition. First, the detection module uses the temporal information to detect small objects in the video. Second, the correlation filter is combined with Convolution neural network feature to track the vehicles. Finally for accurate tracking of the vehicle under the complex condition the alternate template is used to store the template of the target by estimating the speed of the target by incorporating an optical flow method. Results showed that our approach outperforms most state-of-the-art tracking approaches. IndexTerms – Tracking, CNN, Correlation filter, alternate template, surveillance.
[11C]flumazenil Binding Is Increased in a Dose-Dependent Manner with Tiagabine-Induced Elevations in GABA Levels

Evidence indicates that synchronization of cortical activity at gamma-band frequencies, mediated through GABA-A receptors, is important for perceptual/cognitive processes. To study GABA signaling in vivo, we recently used a novel positron emission tomography (PET) paradigm measuring the change in binding of the benzodiazepine (BDZ) site radiotracer [11C]flumazenil associated with increases in extracellular GABA induced via GABA membrane transporter (GAT1) blockade with tiagabine. GAT1 blockade resulted in significant increases in [11C]flumazenil binding potential (BPND) over baseline in the major functional domains of the cortex, consistent with preclinical studies showing that increased GABA levels enhance the affinity of GABA-A receptors for BDZ ligands. In the current study we sought to replicate our previous results and to further validate this approach by demonstrating that the magnitude of increase in [11C]flumazenil binding observed with PET is directly correlated with tiagabine dose. [11C]flumazenil distribution volume (VT) was measured in 18 healthy volunteers before and after GAT1 blockade with tiagabine. Two dose groups were studied (n = 9 per group; Group I: tiagabine 0.15 mg/kg; Group II: tiagabine 0.25 mg/kg). GAT1 blockade resulted in increases in mean (± SD) [11C]flumazenil VT in Group II in association cortices (6.8±0.8 mL g−1 vs. 7.3±0.4 mL g−1;p = 0.03), sensory cortices (6.7±0.8 mL g−1 vs. 7.3±0.5 mL g−1;p = 0.02) and limbic regions (5.2±0.6 mL g−1 vs. 5.7±0.3 mL g−1;p = 0.03). No change was observed at the low dose (Group I). Increased orbital frontal cortex binding of [11C]flumazenil in Group II correlated with the ability to entrain cortical networks (r = 0.67, p = 0.05) measured via EEG during a cognitive control task. These data provide a replication of our previous study demonstrating the ability to measure in vivo, with PET, acute shifts in extracellular GABA.
Antioxidant activity of orange peel powder in ghee at accelerated temperature

Antioxidant potential of orange peel powder in ghee was demonstrated. Orange peel powder (1, 1.5 and 2%) was added in to butter and prepared ghee and stored for accelerated storage study at 60±2°C. Ghee with BHA (0.02%) and control (without any additives) were also prepared, stored and analyzed for comparison during the study. Peroxide value and thiobarbuturic acid (TBA) of ghee samples stored at accelerated condition (60°C±2) were analyzed at 4day interval during 16day storage period. Peroxide value and TBA were observed to increase in all the samples with highest in the control. Increase in peroxide value was least in the sample treated with 2% orange peel powder whereas the sample treated with BHA was observed with lowest increase in TBA value. Orange peel powder can be utilized as a source of natural antioxidant for reducing oxidative deterioration in ghee.
Does Personality Matter in the Evaluation of ERP Systems? Findings from a Conjoint Study

Most leading organizations, in all sectors of industry, commerce and government are dependent upon ERP for their organizational survival. Yet despite the importance of the decision to adopt ERP, IS research has so far neglected to comprehensively study the evaluation of ERP systems in general, and the impact of individual characteristics of IS managers on the ERP acquisition decision in particular. This study is the first of its kind to examine the impact of personality traits of IS managers on the relative importance they ascribe to evaluation criteria in ERP selection. We present the results which provide interesting insights into what evaluation criteria are more or less important for IS managers with different personality styles. In line with findings at the intersection of personality and IS research, we found that the personality dimensions of the five-factor model do considerably matter in ERP evaluation in the sense that the relative importance ascribed to evaluation criteria are affected by individual personality traits. Theoretical and practical implications are derived from our findings to advance insights for ERP adopters and vendors into the ERP evaluation process and to enhance the precision of IS theory.
Allopolyploid Origin of Chenopodium album s. str. (Chenopodiaceae): A Molecular and Cytogenetic Insight

Reticulate evolution is characterized by occasional hybridization between two species, creating a network of closely related taxa below and at the species level. In the present research, we aimed to verify the hypothesis of the allopolyploid origin of hexaploid C. album s. str. , identify its putative parents and estimate the frequency of allopolyploidization events. We sampled 122 individuals of the C. album aggregate, covering most of its distribution range in Eurasia. Our samples included putative progenitors of C. album s. str. of both ploidy levels, i.e. diploids (C. ficifolium, C. suecicum) and tetraploids (C. striatiforme, C. strictum). To fulfil these objectives, we analysed sequence variation in the nrDNA ITS region and the rpl32-trnL intergenic spacer of cpDNA and performed genomic in-situ hybridization (GISH). Our study confirms the allohexaploid origin of C. album s. str. Analysis of cpDNA revealed tetraploids as the maternal species. In most accessions of hexaploid C. album s. str. , ITS sequences were completely or nearly completely homogenized towards the tetraploid maternal ribotype; a tetraploid species therefore served as one genome donor. GISH revealed a strong hybridization signal on the same eighteen chromosomes of C. album s. str. with both diploid species C. ficifolium and C. suecicum. The second genome donor was therefore a diploid species. Moreover, some individuals with completely unhomogenized ITS sequences were found. Thus, hexaploid individuals of C. album s. str. with ITS sequences homogenized to different degrees may represent hybrids of different ages. This proves the existence of at least two different allopolyploid lineages, indicating a polyphyletic origin of C. album s. str.
Effect of simultaneous therapy of arthrocentesis and occlusal splints on temporomandibular disorders: anterior disc displacement without reduction

Objectives This study sought to evaluate the effect of simultaneous application of arthrocentesis and occlusal splint. Materials and Methods A retrospective study of 43 patients (3 males, 40 females) whose symptoms had improved was conducted at the Department of Oral and Maxillofacial Surgery, Dong-A University Hospital between 2008 and 2010. Subjects were divided into three groups: Group A (17 patients with arthrocentesis and occlusal splints simultaneously applied), Group B (13 patients whose symptoms did not improve with occlusal splints, undergoing arthrocentesis after occlusal splint use for 8 weeks), and Group C (13 patients that only used occlusal splints). We compared these groups in maximum comfortable opening (MCO) and the visual analogue scale of pain and noise. Follow-up was performed at 1 week, 1 month, 3 months, and 6 months. Results The improvement of symptoms was noted in all three groups, but Group A had a quicker improvement than the other groups, in terms of pain reduction and MCO increases. Conclusion The simultaneous application of arthrocentesis and occlusal splints can reduce patient discomfort more quickly.
Challenging Oral Contraception after Weight Loss by Bariatric Surgery

As surgical weight loss becomes more commonly performed in fertile women, adequate contraception is more frequently becoming an issue. The purpose of this article is to appraise the literature to ascertain whether the use of oral contraception is effective and adequate after bariatric surgery. The literature search revealed that the combination of lower oral contraception dosages and surgical gastrointestinal disturbances might place patients at higher risks of unintended pregnancy. Until clinical trials show its efficacy, physicians should use oral contraception with prudence after bariatric surgery.
Childhood family violence and adult recurrent depression.

Although previous research has shown that childhood adversity has long-term effects on adult depression, little is known about the causal pathways involved in these effects. In this report data from a two-wave longitudinal survey of the U.S. household population are used to study these pathways as they affect the association between childhood family violence and adult recurrence of depression. We focus on recurrence of depression because most episodes of clinically significant depression in adulthood occur to persons with a history of depression. We find that chronic interpersonal stress in adulthood mediates the effect of childhood family violence on recurrence of depression, and that childhood family violence modifies the effect of chronic adult interpersonal stress on recurrence of depression. Furthermore, in the absence of chronic adult interpersonal stress there is no association between childhood family violence and adult recurrence of depression.
Comparing the Effect of Two Educational Programs on the Quality of Life of Hemodialysis Patients in Iran

Background: Various researchers have shown that the health level, performance status, and quality of life (QOL) are often less than expected especially in hemodialysis (HD) patients. Objectives: This study aimed to determine the effect of the two methods of educational programs on health- related QOL (HRQOL) in Iranian HD patients. Patients and Methods: In this quasi-experimental, pretest-posttest interventional study, we employed each subject as his/her own control. The study was conducted at the dialysis units in three major general hospitals affiliated with Ahvaz Jundishapur University of Medical Sciences. A total of 90 HD patients were randomly allocated to two 45-patient groups of oral and video education programs, respectively. The educational programs included dietary and fluid regimens, the care of fistula and skin, and stress management. HRQOL was assessed in both groups using a Farsi version of the Short Form Health Survey (SF-36) before and after the educational programs. Repeated measures analysis of variance and ANOVA were used for data analysis through SPSS. Results: SF-36 domains of physical functioning (P < 0.021), role physical (P < 0.031), social functioning (P < 0.001) and mental health (P < 0.001) were significantly increased in both oral and vide education groups after the interventions. There was no difference in the effectiveness of the two educational programs. Conclusions: Appropriate interventions may potentially lead to improvement in the HRQOL of these patients. Therefore, video education as an effective, inexpensive, simple, and attractive method is recommended for HD patients.
Evaluation of Microbial and Nutritional Quality of Fermented Dried Roasted Thick Porridge (Mkarango)

Most of the products of maize flour fermentation in Kenya undergo wild fermentation in a natural process. One of these is locally roasted maize flour commonly known by its local name Mkarango which is popular in the Western region of Kenya where it is used in different ways. Mkarango is mostly made through wild fermentation which is known to pose health risks as it is unhygienic and time-consuming, with the quality of the resultant product being inconsistent. The aim of this study was to evaluate the population of lactic acid bacteria, and sensory characteristics of dried roasted thick porridge (mkarango). Six different mkarango products made with addition of Lactobacillus plantarum and Lactobacillus brevis in different ratios were studied for microbial quality, mineral element content and sensory characteristics. Titratable acidity and pH properties of the products were also determined. These were done following recommended standards. After 24 hours of fermentation, products with Yeast+ L. plantarum+ L. brevis (1:2) and Milk+ L. plantarum+ L. brevis (1:2) had the highest pH values (5.12) while products with Milk+ L. plantarum+ L. brevis (2:1) had the lowest pH values (4.8). Yeast, molds, and Lactic Acid Bacteria had the highest in all the samples tested while Enterobacteriaceae the least. The overall acceptability of the product of the product prepared from Milk + L. plantarum + L. brevis (2:1) had the final score of 4.7 on the 5-point hedonic scale. The results of the trace elements zinc and iron ranged from 2.7 mg/100 g to 3.9 mg/100 g and 2.7 mg/100 g to 16.9 mg/100 g on the product respectively. Fermentation creates an environment that is conducive for the population of lactic acid bacteria. This results in increased volume of lactic acid that is responsible for improved nutritional quality of Mkarango.
Biogas production from thin stillage . Exploring the microbial response to sulphate and ammonia

The biogas plant in Norrköping (Tekniska verken i Linköping AB, publ.), Sweden, operates with thin stillage, a residue from bio-ethanol fermentation, as the main feedstock. Thin stillage is energy-rich due to its high protein content, but due to its high nitrogen and sulphate content is a somewhat complicated feedstock. The high nitrogen concentration results in inhibition of the microbial process and also selects for nitrogentolerant, but slow-growing, syntrophic acetate-oxidising bacteria (SAOB). The high sulphate concentration in the feedstock results in production of toxic and inhibitory sulphides through the activity of sulphate-reducing bacteria (SRB). Measures currently applied at Norrköping biogas plant to optimise the degradation of thin stillage include: i) use of mesophilic temperature and addition of hydrochloric acid, ii) use of long hydraulic retention time and iii) addition of iron and trace elements. This thesis investigated how to obtain a more efficient biogas process treating thin stillage, with Norrköping biogas plant as the model plant. It also explored the role of SRB in the anaerobic process at high nitrogen content and sought to identify optimal conditions for ammonia-tolerant methane-producing microorganisms. This was done by measuring SRB abundance in several large-scale biogas processes to identify conditions resulting in reduced numbers. In parallel, the effects of increasing temperature and organic load, calcium addition and a two-stage strategy were evaluated in laboratory studies. The results showed a correlation between high ammonia level and temperature with decreased abundance of SRB, but none of the operating strategies tested proved successful in repressing sulphate reduction. However, increasing ammonia and/or organic loading rate influenced both the acetogenic and methanogenic community, including potential SAOB. Moreover, increasing the temperature to 44 oC resulted in increased abundance of thermotolerant SAOB and their partner methanogen and higher biogas yield (+22%). A maximum ammonia threshold concentration of approximately 1.1 g L was identified. Application of the findings reported in this thesis has resulted in increased process stability in biogas plants in Sweden.
TaintScope: A Checksum-Aware Directed Fuzzing Tool for Automatic Software Vulnerability Detection

Fuzz testing has proven successful in finding security vulnerabilities in large programs. However, traditional fuzz testing tools have a well-known common drawback: they are ineffective if most generated malformed inputs are rejected in the early stage of program running, especially when target programs employ checksum mechanisms to verify the integrity of inputs. In this paper, we present TaintScope, an automatic fuzzing system using dynamic taint analysis and symbolic execution techniques, to tackle the above problem. TaintScope has several novel contributions: 1) TaintScope is the first checksum-aware fuzzing tool to the best of our knowledge. It can identify checksum fields in input instances, accurately locate checksum-based integrity checks by using branch profiling techniques, and bypass such checks via control flow alteration. 2) TaintScope is a directed fuzzing tool working at X86 binary level (on both Linux and Window). Based on fine-grained dynamic taint tracing, TaintScope identifies which bytes in a well-formed input are used in security-sensitive operations (e.g., invoking system/library calls) and then focuses on modifying such bytes. Thus, generated inputs are more likely to trigger potential vulnerabilities. 3) TaintScope is fully automatic, from detecting checksum, directed fuzzing, to repairing crashed samples. It can fix checksum values in generated inputs using combined concrete and symbolic execution techniques. We evaluate TaintScope on a number of large real-world applications. Experimental results show that TaintScope can accurately locate the checksum checks in programs and dramatically improve the effectiveness of fuzz testing. TaintScope has already found 27 previously unknown vulnerabilities in several widely used applications, including Adobe Acrobat, Google Picasa, Microsoft Paint, and ImageMagick. Most of these severe vulnerabilities have been confirmed by Secunia and oCERT, and assigned CVE identifiers (such as CVE-2009-1882, CVE-2009-2688). Corresponding patches from vendors are released or in progress based on our reports.
Anterior flaps anastomosis in external dacryocystorhinostomy.

PURPOSE To evaluate the outcome of the modified technique of external dacrycystorhinostomy with anterior flaps anastomosis only. METHODS This prospective study included 52 patients with lacrimal drainage system disorders who underwent the modified technique of external dacrycystorhinostomy with anterior flaps anastomosis only. In this modified procedure of external dacryocystorhinostomy, anastomosis of anterior flaps only was created by suturing anterior flaps of the lacrimal sac and nasal mucosa, whereas posterior flaps were excised. The success rate and potential complications were recorded during the follow-up period. RESULTS The mean age of the patients was 44.6 +/- 9.9 SD years, including 37 females and 15 males. Mean of follow up was 17.1 +/- 1.8 SD months. Intraoperative complications, hemorrhage occurred in 3 cases (5.8%) and laceration of the nasal mucosa in 2 cases (3.8%). The surgery was uneventful in 47 cases (90.4%). The postoperative complication was closure of the anastomosis that occurred in 2 cases (3.8%). The success rate was evaluated by lacrimal patency to irrigation and relief of epiphora. Fifty patients (96.2%) showed a patent lacrimal system to irrigation and relief of epiphora, 2 patients (3.8%) had recurrence of epiphora and not patent lacrimal system to irrigation. CONCLUSION This modified technique of external dacryocystorhinostomy with anterior flaps anastomosis only simplifies the surgical procedure and is effective in the management of obstruction of lacrimal drainage system beyond the common canalicular opening. Although it is simpler, quicker and easier to master the surgical technique, external dacryocystorhinostomy with anterior flaps anastomosis only shows a success rate comparable with those found in traditional external dacryocystorhinostomy. Further studies with larger series of cases are necessary.
Evolutionary conservation of surface molecules that distinguish T lymphocyte helper/inducer and cytotoxic/suppressor subpopulations in mouse and man

We describe the biochemical properties and cell surface distributions of three human T cell antigens (Leu-1, Leu-2a, and Leu-2b) which we postulate to be the homologues of the Lyt-1, Lyt-2, and Lyt-3 antigens that distinguish functional T cell subsets in the mouse. Leu-l, like Lyt-1, is on all thymocytes and peripheral T cells and is present in greater amounts on the helper/inducer subset than on the cytotoxic/suppressor subset. Both antigens increase in parallel fashion during T cell maturation in the thymus and each antigen is carried on a single 67,000-molecular weight (relative) (M(r)) polypeptide chain. Surprisingly, Leu-1 and Lyt-1 each are also expressed in readily detectable amounts on some B celI Ieukemias but not detectably so on normal B cells. Leu-2a and Leu-2b are antigens found only on suppressor/cytotoxic cells in the human and are very similar to the murine Lyt-2 and Lyt-3 antigens. In both species, the two antigens are on the same disulfide- linked multimeric molecules. Disulfide-bond reduction in both species yields subunits of similar size and charge. Lyt-3 and Leu-2b are extremely sensitive to trypsin digestion on viable cells whereas Lyt-2 and Leu-2a are much less so. A different membrane antigen, Leu-3, is an exclusive marker of the helper/inducer subset in man. No mouse homologue for this 55,000-M(r) protein is known. The maintenance of the homologous molecules on functionally distinct T cell subpopulations in two evolutionarily distant species suggests that the Lyt and Leu antigens perform essential functions for the cells on which they are found.
Grandfather Involvement and Aging Men’s Mental Health

The mental health of aging men is an understudied social issue. Although it is widely accepted that meaningful family relationships are associated with fewer depressive symptoms and greater positive affect, scholars have largely overlooked relationships between grandfathers and grandchildren as being beneficial to men’s mental health. This study investigates the differences in the depressive symptoms and positive affect of 351 grandfathers. Using a cluster analytic technique, participants were categorized as involved, passive, and disengaged based on their frequency of contact, level of commitment, and participation in activities with grandchildren. Comparative analyses indicate that involved grandfathers had fewer depressive symptoms than disengaged grandfathers. Involved grandfathers had significantly higher scores on positive affect than disengaged grandfathers, and passive grandfathers had significantly higher scores on positive affect than disengaged grandfathers. This study provides evidence that grandfather–grandchild relationships influence aging men’s mental health. Implications for practitioners working with aging men are discussed.
