Extracting and Modeling Useful Information from Videos for Supporting Continuous Queries by MANISH KUMAR ANNAPPA

Extracting and Modeling Useful Information from Videos for Supporting Continuous Queries MANISH KUMAR ANNAPPA, M.S. The University of Texas at Arlington, 2016 Supervising Professor: Dr. Sharma Chakravarthy Automating video stream processing for inferring situations of interest has been an ongoing challenge. This problem is currently exacerbated by the volume of surveillance/monitoring videos generated. Currently, manual or context-based customized techniques are used for this purpose. To the best to our knowledge the attempted work in this area use a custom query language to extract data and infer simple situations from the video streams, thus adding an additional overhead to learn their query language. Objective of the work in this thesis is to develop a framework that extracts data from video streams generating a data representation such that simple “what-if” kind of situations can be evaluated from the extracted data by posing queries in a Non-procedural manner (SQL or CQL without using any custom query languages). This thesis proposes ways to pre-process videos so as to extract the needed information from each frame. It elaborates on algorithms and experimental results for extracting objects, their features (location, bounding box, and feature vectors), and their identification across frames, along with converting all that information into an expressive data model. Pre-processing of video streams to extract queryable represen-
Primeros casos de infección canina con Hepatozoon canis en la ciudad de Cúcuta, Colombia

Se describen dos casos de caninos infectados con Hepatozoon canis en la ciudad de Cúcuta, Colombia. La primera paciente de 18 meses de edad llegó a consulta con vómitos, anorexia y pérdida progresiva de peso. En el segundo caso se pretendía realizar ovariohisterectomía preventiva, pero en los exámenes clínicos prequirúrgicos presentó anemia. Para los dos casos, el diagnóstico fue mediante extendido sanguíneo, observado a 100X. Para el segundo caso, el diagnóstico se confirmó con la prueba de PCR. El tratamiento instaurado fue sintomático, usando fármacos como oxitetraciclina y doxiciclina. Este es el primer reporte de hepatozoonosis en la ciudad de Cúcuta.
Augmented Advising

Augmenting academic advising in the era of smart cognitive computing technologies creates new dynamics of engagement that can help academic advising evolve toward a learning-centered paradigm. We examined the self-directed learning readiness of students selected through demographic variables. The results indicate that differences in employment experience, length of employment, and grade point average (GPA) are statistically significant with regard to self-directed learning readiness scores. Preparing learners for self-directed processes can augment student development when purposefully positioned in a learning-centered approach with continuity across mobile, cloud, and cognitive technology–based learning platforms and in components of academic advising processes.
User Perceived Value and Continued Participation in Barrage Video

It is a reality that barrage video is getting prevailing for being able to satisfy users' demand of real-time interaction. In the cut throat competition, how to hold a person’s attention effortlessly and promote continued participation is still a vital issue. This paper aims to study the relation between user perceived values and continued participation in the context of barrage video. To obtain practical implications, a survey has been implemented. The results reveal that information value has positive impacts on continued participation behavior, and its effect is completely mediated by satisfaction. Entertainment value can also promote the continued participation behavior, in which satisfaction plays a part of mediating role. Social value has no significant direct influence on the continued participation behavior.
Paramyxoviruses crossing the host membrane: mechanisms for entry

The paramyxovirus family is a group of enveloped, negative-strand RNA viruses that includes common and highly infectious human pathogens such as mumps, measles, respiratory syncytial virus, human metapneumovirus and the closely related, highly lethal zoonotic Hendra and Nipah viruses. Paramyxoviruses are unique in that they have two envelope glycoproteins that mediate virion binding and membrane fusion, instead of a single glycoprotein that fulfills both functions. The following text provides a review on how the two paramyxovirus glycoproteins, the attachment protein and fusion protein, interact with each other, and to which host-cell receptors they bind, to ensure membrane fusion and entry into the host cell. In the Paramyxovirinae subfamily, binding of the attachment protein to an entry receptor triggers the fusion protein, which in turn drives membrane fusion. While biochemical studies and recently solved crystal structures have shed some light on this process, the exact mechanism by which the attachment protein triggers the fusion protein upon receptor binding, remains to be elucidated for any of the Paramyxovirinae . In the Pneumovirinae subfamily on the other hand, the attachment protein is not necessary to achieve membrane fusion and the fusion protein mediates receptor binding as well as membrane fusion. The current view is that virus entry in vivo is a highly dynamic process that involves a complex interaction between viral glycoproteins on the one hand and host cell receptors on the other. Furthermore, individual paramyxovirus species might employ multiple entry pathways, using more than one type of receptor, relying on fusion at the plasma membrane as well as on fusion after endocytosis.
Towards smarter ranging pixels with high dynamic range : sensitivity-tuning of current assisted photonic demodulators

The peculiarities of Time-of-Flight ranging with CMOS sensors with respect to conventional CMOS imaging allow new ways to enhance dynamic range of these CMOS ranging sensors. This paper discusses how a current-assisted photonic demodulator can be modified to provide enhanced dynamic range. An extra node provides tunable sensitivity to the detector without interfering with the photonic demodulation properties of the device. It can be used to construct smart ranging pixels with extended dynamic range.
Encystment of Acanthamoeba and Evaluating the Biobus Program

Acanthamoeba are ubiquitous protists that play an environmental role in regulating microbial diversity; they also occasionally cause infections of the eye (Acanthamoeba keratitis) and brain (granulomatous amoebic encephalitis). These organisms exhibit two distinct phenotypes. The trophozoite form dominates in favorable conditions, in which the Acanthamoeba move through the extension of pseudopodia, engulfing microbes and other particles. During stressful conditions, the Acanthamoeba undergo a process of encystment, in which they build a double cell wall and become relatively inactive. The cyst form can survive years until more favorable conditions arise, at which point they may excyst. For this study, multiple laboratory encystment methods were compared to determine the percent encystment and the different viabilities of laboratory-produced cysts. Furthermore, four different encystment genes were targeted for development of a primer library for reverse-transcription, polymerase chain reaction expression studies. The library was developed using sequences accessed from various databases, including NCBI and EMBL; primers were screened through polymerase chain reaction, and those primers producing positive results were used to further screen cellular RNA that was extracted from encysting cells over various time points during the encystment process, and using various encystment media. Using these methods, target gene involvement in the encystment process was compared between species and encystment methods. These studies lay the foundation for quantitative gene expression analysis, and provide the basis for comparison of various encystment methods.

Effects of azole fungicides on the function of sex and thyroid hormones

(17/10/2019) Effects of azole fungicides on the function of sex and thyroid hormones Azole-fungicides are frequently used in Denmark. Epoxiconazole, propiconazole, and tebuconazole had endocrine disrupting properties in cell based assays. In rats, epoxiconazole and tebuconazole increased gestational length, maternal progesterone level, and masculinized female-offspring. Besides, tebuconazole caused feminization of male-offspring. Similar effects were previously demonstrated for prochloraz. The results indicate that azole-fungicides in general have endocrine disrupting properties.
Trust Network-based Filtering to Retrieve Trustworthy Word-of-Mouth Information

We propose a method to retrieve trustworthy information from a word-of-mouth community space that could include inappropriate information. In a ubiquitous information society, high anonymity could cause some problems concerning human rights infringements, such as slander and invasion of privacy. On the other hand, unless anonymity is guaranteed at a certain level, free expression and speech would not be possible and may lead to an inactive information society. As a counter-measure to such problems, information rating-based ﬁltering was examined in previous work. However, some diﬃculties such as the infringe-ments of freedom of expression and the objective authenticity of the rating results have been pointed out. In this research, we pay attention to the reliance on relationships between people, and construct a model in which information is valued when it comes from people who can be relied on. Also, we aim to construct a framework for evaluating the trustwor-thiness of information by forming a community that is generally known as the ”web of trust” model.
Preparation of Sm−Fe−N Bulk Magnets with High Maximum Energy Products

In an effort to increase the maximum energy product ((BH)max) and coercivity (HcJ) of Zn-bonded Sm−Fe−N magnets, we developed a process for preparing Sm−Fe−N and Zn powders with low oxygen contents and subjected them to spark plasma sintering. The oxygen content, remanence, and coercivity of the Sm−Fe−N powder were 0.22 wt%, 151 A·m2·kg−1, and 0.72 MA·m−1, respectively. The oxygen content and secondary average particle size of the Zn powder were 0.083 wt% and 0.93 μm, respectively. The magnetic properties of the Zn-free Sm−Fe−N magnets included an HcJ of 0.86 MA·m−1 and a (BH)max of 188 kJ·m−3, while the Zn-bonded (10 wt%) Sm−Fe−N magnets exhibited excellent magnetic properties with a (BH)max of 200 kJ·m−3 and an HcJ of 1.28 MA·m−1. Compared with previous studies, this is the high (BH)max observed for a Sm−Fe−N bulk magnet simultaneously displaying a high HcJ. The (BH)max of the Zn-bonded magnets was greater than that of the Zn-free magnets owing to the higher relative density of the former. Therefore, Zn is an effective binder for increasing not only the coercivity but also the density of Sm−Fe−N magnets. Consequently, the procedure reported herein permits the successful preparation of high-performance Sm−Fe−N bulk magnets.
Fiscal Policy and Sectoral Output Performance in Nigeria

In this study, the differential effects of fiscal policy variables on the performance of the key sectors of the economy namely; Industrial, Agricultural and Service sectors were investigated using an Autoregressive Distributed Lag (ARDL) and Error Correction Model (ECM) for the period of 1970-2018. Obtained results indicated that while both domestic and foreign debts have no significant effects on the three sectors examined in the short run, it was observed that foreign debt and government consumption expenditure have incremental effects on industrial sector’s output. Similarly, it was observed that while domestic debt crowd-in agricultural and services sectors’ outputs, it has a crowd-out effect on industrial output in the long run. It is also noteworthy that while government investment expenditure has positive effect on industrial output, its effects on agricultural output is detrimental in the long run. This implies that government can neutralize the negative effects of its domestic debt on industrial sector’s output either by increasing its consumption expenditure or rely more on foreign debt. It is recommended that government should focus more on investing in infrastructure such as irrigation, access road to farm land, storage facilities, processing equipment like milling machine, etc. in other to boost productivity in the sector.
Effect on length of stay (LOS) and cost of hospitalization by using Vacuum-assisted Closure (VAC) therapy in chronic diabetic foot ulcers: Experience with limited resources in a developing country

Background Managing diabetic foot ulcers in developing countries is demanding. Sri Lankan literature on the use of Vacuum-assisted Closure (VAC) is scarce due to lack of overall guidelines and awareness. This prospective cohort study evaluates the effectiveness of VAC therapy, effect on length of hospital stay (LOS) and cost of hospitalization in chronic diabetic foot ulcers. Methods Prospective study was carried out from March 2018 to February 2019. Fifty patients were selected. Based on the patient preference and informed written consent, 28 patients were treated with VAC therapy and rest were managed with standard surgical protocols. Haematological, serological and bacterial cultures from wounds were done in all patients. The ulcers were classified by Wagner classification. All patients were treated with antibiotics until the systemic infection settles. VAC dressing was changed every 72 hours. Ethical approval was obtained from the education and research ethical committee of Nawaloka Hospital PLC.Student t-test, regression analysis and chi-square were used for data analysis. Results The most affected were in 50 to 60 years of age [(50%, mean age; 59±7.7 years)]with a male preponderance (64%). The commonest presentation was cellulitis with abscess formation (66%). Majority of the ulcers (54%) were Wagner Type 3 and in hind foot (60%). Average VAC applied days was 11±0.98. There was no statistically significant difference between age, sex and levels of inflammatory markers between the two groups (P>0.05). There were significant differencesobserved between VAC and non – VAC groups innumber of surgical debridement (3±0.74 vs 7.8±1.22, p= 0.001);duration of days antibiotic administration [Intra-venous antibiotics; 4.1±0.38 vs 8.23±1.76 (p=0.001) and oral antibiotics; 7.61±0.87 vs 11.5±2.1 (p=0.001)]; Length of stay [(LOS in days) 11.68±0.98 vs 19.86±2.64, (p=0.001)]. Significant reduction of total hospital cost was seen in the VAC group [VAC; (LKR) 645,060±86,600 vs Non-VAC; (LKR) 1,049,800±97,487, (p=0.001)] whilst, having a 63% significant negative effect on final bill. Wounds of all VAC patients were healed. Conclusions Our study showed that VAC therapy reduced the number of surgical debridement, duration of antibiotic administration, LOS and hospital cost.Authors suggest a clinical trial will enhance the evidence of this study.
Incidence of appendicitis and ovarian cyst among female patients presenting with acute abdomen at a tertiary care hospital

Background: Physicians working in casualty are often confronted with acute abdomen and get much more bothered as the diagnosis is not easy. This is due to the fact that the etiology of acute abdomen is always much diversified and the classical findings are masked making the diagnosis difficult. Objective was to study incidence of appendicitis and ovarian cyst among female patients presenting with acute abdomen.Methods: A hospital based follow up study was carried out among 64 cases presented with acute abdomen to the casualty from January 2018 to August 2018. All necessary investigations were done to confirm the etiology of acute abdomen. The cases belonged to surgery and gynecology departments where they were operated. The patients were followed from admission in the casualty to the final outcome. The data was analyzed using proportions.Results: During the study period a total of 15413 patients were admitted in the casualty out of them, 64 (0.42%) presented with acute abdomen. Of these 64 cases, majority i.e. 35 (54.7%) were due to acute appendicitis; 13 cases were due to renal colic and eight cases each were due to ectopic pregnancy and ovarian cyst. The most common age group affected was 21-30 years (62.5%) followed by less than 20 years age (21.9%). 25% of the 64 cases had delayed wound healing and no other complications were reported. No death was recorded.Conclusions: Authors achieved excellent results as there were no major complications and no death was recorded. Thus, meticulous diagnosis and prompt treatment can save patient life and at the same time rate of complications can be reduced.
Duel-band filter with high out-of-band rejection using ACSRR-SIW technology

A completely asymmetrical dual-band micro-strip filter combined with a complementary split ring resonator (CSRR) consisting of a circle and a square, and substrate integrated waveguide (SIW) is presented in this paper. The proposed design can be applied in the Industrial Scientific Medical (ISM) band. The CSRR of this completely asymmetrical filter, which has both square and circular parts, can realize two distinct passbands and shows higher out-of -band rejection than symmetrical filters; it is an asymmetrical complementary split ring resonator (ACSRR). The out-ofband rejection level between two passbands can reach 40 dB, compared to 35 dB in a circular filter and 30 dB in a square filter. The measured results are in good agreement with simulated results. key words: asymmetrical complementary split ring resonator (ACSRR); substrate integrated waveguide (SIW); dual-band filter; high out-of-band rejection Classification: Microwave and millimeter wave devices, circuits, and hardware
Weakly Supervised Learning of Deformable Part-Based Models for Object Detection via Region Proposals

The success of deformable part-based models (DPMs) for visual object detection relies on a large number of labeled bounding boxes. With only image-level annotations, our goal is to propose a model enhancing the weakly supervised DPMs by emphasizing the importance of location and size of the initial class-specific root filter. To adaptively select a discriminative set of candidate bounding boxes as this root filter estimate, first, we explore the generic objectness measurement to combine the most salient regions and “good” region proposals. Second, we propose learning of the latent class label of each candidate window as a binary classification problem, by training category-specific classifiers used to coarsely classify a candidate window into either a target object or a nontarget class. Finally, we design a flexible enlarging-and-shrinking postprocessing procedure to modify the DPMs outputs, which can effectively match the approximative object aspect ratios and further improve final accuracy. Extensive experimental results on the challenging PASCAL Visual Object Class 2007 and the Microsoft Common Objects in Context 2014 dataset demonstrate that our proposed framework is effective for initialization of the DPM's root filter. It also shows competitive final localization performance with state-of-the-art weakly supervised object detection methods, particularly for the object categories that are relatively salient in the images and deformable in structures.
Optical trapping of Rayleigh dielectric particles using the evanescent wave of two totally internally reflected interfering beams

In this paper, the optical force acting upon Rayleigh dielectric particles produced by evanescent wave of two totally internally reflected interfering beams is investigated. Both gradient and scattering forces are calculated and the stability conditions for effective trapping of particles are analyzed. Results show that evanescent wave due to interference of two laser beams can be used to trap Rayleigh particles along a column parallel to the interface.
Organ Specific Head Coil for High Resolution Mouse Brain Perfusion Imaging using Magnetic Particle Imaging

Magnetic Particle Imaging (MPI) is a novel and versatile imaging modality developing towards human application. When up-scaling to human size, the sensitivity of the systems naturally drops as the coil sensitivity depends on the bore diameter. Thus, new methods to push the sensitivity limit further have to be investigated to cope for this loss. In this paper a dedicated surface coil improving the sensitvity in cerebral imaging applications was developed. Similar to MRI the developed surface coil improves the sensitivity due to the closer vicinity to the region of interest. With the developed surface coil presented in this work, it is possible to image tracer samples containing only 896 pg iron and detect even small vessels and anatomical structures within a wild type mouse model. As current sensitivity measures are dependent on the tracer system a new method for determining a sensitivity measure without this dependence on the tracer is presented and verified to enable comparison between MPI receiver systems.
War of the Hashtags: Trending New Hashtags to Override Critical Topics in Social Media

— Hashtags play a cardinal role in the classification of topics over social media. A sudden burst on the usage of certain hashtags, representing specific topics, give rise to trending topics. Trending topics can be immensely useful as it can spark a discussion on a particular subject. However, it can also be used to suppress an ongoing pivotal matter. This paper discusses how a significant economic crisis was covered by triggering a current trending topic. A case study on politics in India has been studied over the past two months. The analysis shows how the issue on inflation was attacked by the exercise of a new constitutional law over media. Hashtags used to discuss the topics were scrutinized, and we notice a steep ascend of the more recent topic and an eventual drop in discussions over the previous issue on inflation. Balancing the influence of hashtags on social media can be employed. Still, it can be equally challenging since some hashtags that represent the need of the hour topics should be given more importance, and evaluating such issues can be hard.
A Review of an Old Dilemma: Demosaicking First, or Denoising First?

Image denoising and demosaicking are the first two crucial steps in digital camera pipelines. In most of the literature, denoising and demosaicking are treated as two independent problems, without considering their interaction, or asking which should be applied first. Several recent works have started addressing them jointly in works that involve heavy weight neural networks, thus incompatible with low power portable imaging devices. Hence, the question of how to combine denoising and demosaicking to reconstruct full color images remains very relevant: Is denoising to be applied first, or should that be demosaicking first? In this paper, we review the main variants of these strategies and carry-out an extensive evaluation to find the best way to reconstruct full color images from a noisy mosaic. We conclude that demosaicking should applied first, followed by denoising. Yet we prove that this requires an adaptation of classic denoising algorithms to demosaicked noise, which we justify and specify.
