Masters Thesis: Multi-frame deep learning models for action detection in surveillance videos

Visual surveillance technologies are increasingly being used to monitor public spaces. These technologies process the recordings of surveillance cameras. Such recordings contain depictions of human actions such as "running", "waving", and "aggression". In the field of computer vision, automated detection of human actions in videos is known as action detection. Recently, deep learning models have been proposed for the task of action detection. Deep learning models for this task can be grouped into single-frame models and multi-frame models. Single-frame models detect actions using individual frames of videos whereas multi-frame models detect actions using sequences of frames. This thesis proposes to use multi-frame models as compared to single-frame models for action detection in surveillance videos. To compare multi-frame and single-frame models, we implement the ACT-detector [1]. The ACT-detector is a deep learning model that takes as input a sequence of K frames and outputs tubelets (labeled sequences of bounding boxes). We train and evaluate ACT for various values of K on the VIRAT dataset [2]. In our comparison, K = 1 serves as the single-frame model and K > 1 as the multi-frame models. When compared qualitatively, we find that multi-frame models have less missed detections. When compared quantitatively, we find that multi-frame models outperform single-frame models in performance measures such as classification accuracy, MABO, frame-mAP, and video-mAP. To assess whether the improvements of multi-frame models yield purely from the increased number of frames, or also from the temporal order encoded by those frames, we experiment with training multi-frame models on unordered sequences of frames, i.e., sequences for which the frames are shuffled in time. When compared qualitatively, we find that multi-frame models have less precise localization when trained on unordered sequences. When compared quantitatively, we find that multi-frame models perform worse when trained on unordered sequences, indicating that multi-frame models learn temporal dynamics of actions. Nevertheless, even when trained on unordered sequences, multi-frame models outperform single-frame models for action detection in surveillance videos. Master of Science Thesis T. A. Khan
PM21 Gas antisolvent method (GAS method) for crystallization of metal-organic coordination complexes

INTRODUCTION In many industrial domains, crystallization is one of the most important steps to the formulation, purification and isolation of pharmaceutical and chemical products with desired purity and characteristics. Depending on process conditions, crystallization can be achieved by cooling, evaporation or modification of the solvent. The major drawbacks of these methods are the use of high amounts of organic solvent, high temperatures, very expensive washing steps and residual solvent in the final product. The use of a supercritical fluid technology is an alternative to these conventional methods to eliminated or reduce these disadvantages. The use of CO2 as an antisolvent for the controlled precipitation of materials from conventional solvents has been widely applied to the production of a range of materials, including polymers, pharmaceutical chemicals, explosives, superconductors and catalysts. We present the gas antisolvent method (GAS method) as a crystallization process to realize single crystal growth of metal-organic coordination complexes. The diversity of this new class allows the use of MOFs in various fields of application, in particular in the fields of gas storage and separation, catalysis and sensor technology. [1] To study these complex structures, it is necessary to use the single crystal X-ray crystallographic analysis, in which the average arrangement of the atoms can be precisely measured and their positions in the crystal lattice can be determined. The challenge consists in the production of the required single crystals, which in addition to their monocrystalline character also have to show a minimum size of 100 μm, required for the X-ray diffractometer. Conventional crystallization methods used for the preparation of single crystals suitable for X-ray crystallography are, next to the general disadvantages of these methods, extremely time-consuming (weeks to months). [2] With the GAS method, it was possible to produce X-ray-suitable single crystals of already known metal-organic frameworks and to compare them with crystal structures obtained from conventional crystallization methods.

Methodological Tools for Linguistic Description and Typology

This paper presents a methodological tool called Trajectoire that was created to elicit the expression of Path of motion in typologically and genetically varied languages. Designed within the research program TRAJECTOIRE ‘Path (of motion)’, supported by the Fédération de Typologie et Universaux Linguistiques, the Trajectoire elicitation tool aims to systematically explore the morpho-syntactic resources used for the expression of Path and the distribution of spatial information across the sentence, with a specific focus on the (a)symmetry in the expression of Source (the initial point) and Goal (the final point). Its main aim is to facilitate typologically-informed language descriptions, which in their turn can contribute new data to typologically-oriented research. Inspired by the research methods developed at the Max Planck Institute for Psycholinguistics (Nijmegen, NL), the Trajectoire material comprises 76 video-clips consisting of 2 training clips, 55 target clips and 19 fillers, and it includes 3 distinct versions ordering the clips differently to minimize possible routine effects. The 55 target clips vary for several parameters, namely Figure, Ground, the different portions of Path, Deixis, and less systematically, Manner. The scenes filmed in an outdoor natural environment ensure accessibility to non-Western populations. The paper first presents the structure and the use of the elicitation material. On the basis of the data obtained in about 20 different languages and reports by users, both researchers and speakers, it then discusses the advantages and some drawbacks of the Trajectoire elicitation tool, and considers the issue of the tool's dissemination and online open access.
Distribution of Bcl-2 in Odontogenic Cyst and Tumours: Histochemical Study

Introduction: The Odontogenic Keratocyst is known for its aggressiveness, high recurrence rate and transformation of keratinized epithelia to non-keratinized squamous epithelium for which inflammation has been suggested to be responsible. bcl-2 an anti-apoptotic protein, prolongs the life span of epithelial cells and allows proliferation, differentiation and morphogenesis. Materials and method: Study was carried out comprising of 90 cases; [30 Ameloblastoma, 30 Keratocystic Odontogenic tumor and 30 Radicular cyst]. Bcl-2 expression was determined with respect to Localization, Area [percentage] and Intensity of stained cells in epithelium and connective tissue stroma by counting the endothelial, round and fusiform cells. Results: In epithelium bcl-2 expression in Keratocystic Odontogenic tumors was higher followed by Ameloblastoma and lowest in Radicular cyst. Whereas, in connective tissue stroma bcl-2 expression was higher in Keratocystic Odontogenic tumor and Radicular cyst than Ameloblastoma cases. Solid variants showed statistically higher expression as compared to the Unicystic variants of Ameloblastoma [p-value 0.009, 0.033, 0.011, 0.041]. Conclusion: High expression of bcl-2 in KCOT supports the general agreement that some features of OKC are those of a neoplasia. The bcl-2 expression in connective tissue cells suggests that these cells may also be important as epithelial cells in the biological behaviour odontogenic keatocyst.
Repositioning Patients in Chairs—An Improved Method

Proper seated posture is important in health care settings because immobilized patients may be sitting for extended periods. In many situations, a caregiver is required to assist a slouching patient to a proper, more comfortable upright posture. The caregiver is at risk from exposure to the physical demands of this task. This study evaluated exertion and risk to the caregiver using three methods of repositioning patients in chairs in the health care setting. Through application of a new method employing an ergonomically designed device, exertion and risk were reduced. Results from this study indicate that the high-risk occupational activity of repositioning a slouching patient in a chair can be made safer for caregivers.
Beta-Lactamase Resistance of Cephazolin and other Cephalosporins

The turbidities of cultures of bacteria were monitored continuously at 37°C. in a biophotometer. In the early phase of logarithmic growth, at approximately 2 × 107 organisms per ml. , antibiotic was added. A strain of Escherichia coli (E. coli) that was ampicillin-resistant, but cephaloridine-sensitive, produced β-lactamase rapidly as shown by the breakdown of a chromogenic cephalosporin. The E. coli was lysed by cephaloridine 15 minutes after the addition of the antibiotic, but, even with a concentration 8-fold greater than the MIC, after 3.5 hours the antibiotic was not detectable in the culture medium and the strain had recommenced logarithmic growth. In the presence of a concentration of cephazolin 4-fold greater than the MIC the E. coli lysed after 30 minutes and did not recommence growth for 6 hours, indicating much slower destruction of the antibiotic, presumably due to the greater β-lactamase resistance of cephazolin. Similar results were obtained with other E. coli and a strain of Klebsiella pneumoniae.

The effect of cobalt60 radiation on squamous cell carcinomas of the nasal planum of the domestic cat

Squamous cell carcinomas (SCC) are caused by high levels of UVB (B fraction of the ultra violet ray) radiation on susceptible animal tissue. Factors that influence the ultra violet radiation (UV) level in different parts of the world are altitude, intensity and duration of sunlight, and thickness of the ozone layer. South Africa’s UV radiation levels are amongst the highest recorded in the world. The UVB energy enters the squamous cell and damages the DNA, which results in the uncontrolled proliferation of the squamous cells. Ultimately this proliferation of the squamous cells leads to the formation of a squamous cell carcinoma. The normal histology of the well-ordered squamous cell tissue changes from its regular pattern to one of disintegration as the carcinoma grows at the expense of the normal tissue. This clinical study examines the results of 75 feline patients with solar-induced SCC of the nasal planum treated with Cobalt 60 radiation. The cats were grouped clinically according to the severity of the SCC from 1-4, least to worst. The cats were sedated and their nasal planums irradiated on a recognised veterinary fractionated protocol of Monday/Wednesday/Friday. The clinical response was judged by the visual reduction in size and the diminishing aggressiveness of the tumour. This response determined the radiation dose and the number of treatments.

Is valproate promising in cardiac fatal arrhythmias? Comparison of P- and Q-wave dispersion in bipolar affective patients on valproate or lithium–valproate maintenance therapy with healthy controls

Autonomic nerve system is considered to be involved in bipolar affective disorder (BAD) or to be influenced by valproate monotherapy or valproate plus lithium combination. We planned to assess the effects of medication on atrial and ventricular conduction. The electrocardiography records were performed with eligible 15 patients with valproate, 20 patients with lithium–valproate combination use in euthymic phases of BAD and 20 healthy participants. The blood valproate and lithium concentrations in groups were in normal range. The difference in P maximum, P minimum, maximum QTc were statistically insignificant. Minimum QTc (F = 6.36; df = 2; P = 0.003) and QT dispersion (QTD) (F = 5.57; df = 2; P = 0.006) were statistically significant among the groups. There were no significant differences between patient groups among ECG parameters. Minimum QTc was significantly longer in combination group than healthy controls, whereas the QTD values in both patient groups were significantly lower than controls’. Valproate might have some preventive effects on ventricular electrical conduction because of lower QTD in both patient groups. Thus, valproate seems to have cardiac conduction stabilizing effect beside its mood stabilizing aspect. However, this finding needs replication and further corroboration in well-designed studies.

ASSESSING CLINICAL JUDGEMENT WITH STANDARDIZED PATIENTS

: Family physicians and general practitioners see the majority of patients with uncomplicated rheumatic disease, yet information on database collection and clinical judgment in such practices is limited. Trained patients with uncomplicated rheumatic disease (standardized patients) were used to evaluate these abilities in 26 family physicians at the University of Arizona College of Medicine in blinded, but previously consented to, brief new encounters. Ability to formulate an assessment and to plan was evaluated as well as ability to collect diagnostic information. Few physicians explored the psychosocial impact of the illness (4 percent) or the role of depression (0 percent). In the brief encounter with a localized complaint, little inquiry was directed to systemic disease (46 percent). Physicians more uniformly asked about the chief complaint (96 percent) and time of onset (88 percent). Physical examination items most commonly omitted were evaluation of systemic joint involvement (69 percent) and muscle wasting in the involved area (59 percent). Referral occurred on 15 percent of encounters and patient education occurred in 62 percent. Three quarters of physicians developed an adequate assessment and virtually all developed an adequate patient care plan.
A Comparison of Directly Observed Therapy and Self-Administered Therapy Strategies in Treatment of Pulmonary Tuberculosis: A Cohort Study in North of Iran

Weak diagnosis, inadequate and incorrect treatment, emergence of drug resistance and HIV co- epidemic has caused serious problems for tuberculosis control program. The aim of this study was to investigate the efficiency of DOTS strategy in treatment of patients with positive smear pulmonary tuberculosis. This Cohort study was carried out on patients with positive smear pulmonary tuberculosis registered in Mazandaran Diseases Control Center (Iran) from 2005 to 2010. Of 683 registered patients, 362 were in Directly Observed Therapy group and 321 ones were in Self-Administered Therapy group. Specifications of field variables in both groups and their homogeneity were studied using analytical analysis and then treatment results were compared in both groups using Poison Regression and Chi analysis; analysis of treatment results 2 have also been presented in subgroups. 48.1% of patients were male. Patients' average age was 49.73±21.57 years and no significant difference was observed among different ages in terms of their gender (P=0.8). In directly observed therapy group, success and failure levels were 92 and 8 percent respectively, while it was 83.2 and 16.8 in self-administered therapy group. Treatment success in self-administered therapy group was 2% less than that of WHO, while in directly observed therapy group it was 7% more than that of WHO. In a case all health and treatment centers use directly observed therapy, treatment success level will exceed 90% which is beyond the objectives determined by WHO.
The association between calfhood BRDC and subsequent departure from the herd, milk production, and reproduction: an observational, retrospective study

Bovine respiratory disease (BRDC) is a multifaceted disease that causes considerable economic loss in both the beef and dairy industry. However, because there may be lingering effects of BRDC in the dairy industry, the full economic costs of the disease may not be realized. These lingering effects may include an increased departure from the herd, decreased milk production, and decreased reproductive performance. All of these outcomes are affected by multiple variables, but proper statistical modeling can control for many of the different influences. Few studies have attempted to look at the long term effects of calfhood BRDC but consistent associations have not been identified. The objective of this observational, retrospective study was to determine the association between calfhood BRDC prior to 120 d of age and departure from the herd, milk production, and reproductive performance. The association between the occurrence of BRDC with departure from the herd prior to first calving depended on the birth year, but for 5 of the 6 years, animals that contracted BRDC were 1.62 to 4.98 times more likely to leave the herd than animals that did not contract BRDC. In addition, animals that contracted BRDC were also 1.28 times more likely to leave the herd between first and second calving than animals that did not contract BRDC. Furthermore, the age at BRDC occurrence was associated with departure from the herd. Animals that contracted BRDC preweaning were 2.62 times more likely to leave the herd prior to first calving than animals that contracted BRDC post-weaning. However, age of BRDC occurrence was not significantly associated with departure from the herd between first and second calving. The occurrence of BRDC during the first 120 d of life was associated with a 233 kg decrease in lactation-one production, but was not significantly associated with production in subsequent lactations. Finally, calfhood BRDC was not significantly associated with a decreased reproductive performance measured by calving interval. In conclusion, calfhood BRDC negatively impacts productivity both prior to and after first calving.
High-Density Miniaturized Thermal Shift Assays as a General Strategy for Drug Discovery

More general and universally applicable drug discovery assay technologies are needed in order to keep pace with the recent advances in combinatorial chemistry and genomics-based target generation. Ligand-induced conformational stabilization of proteins is a well-understood phenomenon in which substrates, inhibitors, cofactors, and even other proteins provide enhanced stability to proteins on binding. This phenomenon is based on the energetic coupling of the ligand-binding and protein-melting reactions. In an attempt to harness these biophysical properties for drug discovery, fully automated instrumentation was designed and implemented to perform miniaturized fluorescence-based thermal shift assays in a microplate format for the high throughput screening of compound libraries. Validation of this process and instrumentation was achieved by investigating ligand binding to more than 100 protein targets. The general applicability of the thermal shift screening strategy was found to be an important advantage because it circumvents the need to design and retool new assays with each new therapeutic target. Moreover, the miniaturized thermal shift assay methodology does not require any prior knowledge of a therapeutic target's function, making it ideally suited for the quantitative high throughput drug screening and evaluation of targets derived from genomics.
