HLVU : A New Challenge to Test Deep Understanding of Movies the Way Humans do

In this paper we propose a new evaluation challenge and direction in the area of High-level Video Understanding. The challenge we are proposing is designed to test automatic video analysis and understanding, and how accurately systems can comprehend a movie in terms of actors, entities, events and their relationship to each other. A pilot High-Level Video Understanding (HLVU) dataset of open source movies were collected for human assessors to build a knowledge graph representing each of them. A set of queries will be derived from the knowledge graph to test systems on retrieving relationships among actors, as well as reasoning and retrieving non-visual concepts. The objective is to benchmark if a computer system can "understand" non-explicit but obvious relationships the same way humans do when they watch the same movies. This is long-standing problem that is being addressed in the text domain and this project moves similar research to the video domain. Work of this nature is foundational to future video analytics and video understanding technologies. This work can be of interest to streaming services and broadcasters hoping to provide more intuitive ways for their customers to interact with and consume video content

On enhancing the robustness of timeline summarization test collections

Timeline generation systems are a class of algorithms that produce a sequence of time-ordered sentences or text snippets extracted in real-time from high-volume streams of digital documents (e.g. news articles), focusing on retaining relevant and informative content for a particular information need (e.g. topic or event). These systems have a range of uses, such as producing concise overviews of events for end-users (human or artificial agents). To advance the field of automatic timeline generation, robust and reproducible evaluation methodologies are needed. To this end, several evaluation metrics and labeling methodologies have recently been developed - focusing on information nugget or cluster-based ground truth representations, respectively. These methodologies rely on human assessors manually mapping timeline items (e.g. sentences) to an explicit representation of what information a ‘good’ summary should contain. However, while these evaluation methodologies produce reusable ground truth labels, prior works have reported cases where such evaluations fail to accurately estimate the performance of new timeline generation systems due to label incompleteness. In this paper, we first quantify the extent to which the timeline summarization test collections fail to generalize to new summarization systems, then we propose, evaluate and analyze new automatic solutions to this issue. In particular, using a depooling methodology over 19 systems and across three high-volume datasets, we quantify the degree of system ranking error caused by excluding those systems when labeling. We show that when considering lower-effectiveness systems, the test collections are robust (the likelihood of systems being miss-ranked is low). However, we show that the risk of systems being mis-ranked increases as the effectiveness of systems held-out from the pool increases. To reduce the risk of mis-ranking systems, we also propose a range of different automatic ground truth label expansion techniques. Our results show that the proposed expansion techniques can be effective at increasing the robustness of the TREC-TS test collections, as they are able to generate large numbers missing matches with high accuracy, markedly reducing the number of mis-rankings by up to 50%

Myotonic dystrophy in a Pakistani family: a case series and literature review

Myotonic dystrophy also known as (Steinert\u27s disease) is a clinically and genetically heterogeneous multisystem disorder with a prevalence of 1 in 8000 in the general population. It is inherited as an autosomal dominant trait. It is characterized by myotonia, myopathy of voluntary and involuntary muscles, frontal baldness in men, cardiac conduction abnormalities, cataracts, intellectual deterioration and endocrinopathies. Affected men may have gonadal atrophy and infertility. On the other hand women are generally fertile. We report a case series of three individuals belonging to the same family presenting with characteristic features of myotonic dystrophy. The presentation of these cases depicts that this disease can lead to disability, loss of independence and social isolation especially in the elderly. They warrant adequate work up for diagnosis which may sometimes be extensive. Proper genetic counseling of the family is required regarding nature of the disease and with risks and prognosis

Awareness of stroke among general Practitioners

Stroke is the 2nd leading cause of death and 3rd leading cause of disability after cancer and ischemic heart disease. The recognition of acute stroke symptoms and knowledge about timely and prompt referral of a patient for possible thrombolysis is a need of time for which general practitioners (as they have to be the first responders many a times across Pakistan) need to be equipped with the advance knowledge about stroke treatment

Hemichorea Associated with type 2 Diabetes: A Rare Neurological Complication

Diabetic hemichorea/hemiballism is a spectrum of hyper kinetic, involuntary, irregular, purposeless, non-rhythmic, rapid and unsustained movements flowing from one part of the body to another. It involves contra lateral basal-ganglia and often striatum of the brain. Here we are reporting an un-usual case of choreiform movement disorder which was sudden in onset. It was accompanied with abnormally high values of blood glucose. Our patient had a complete remission of symptoms after an adequate control of blood glucose was achieved. This case illustrates the importance and rarity of hyperglycemia as a rare cause of hemichorea. It recovers rapidly and has a good prognosis. Screening for hyperglycemia even in those patients without a prior history of diabetes is very important, once they present with an involuntary movement disorder. Recognition and early treatment is beneficial to prevent adverse outcomes. Today, in the medical literature it is often referred to as C-H-BG (chorea, hyperglycemia, basal ganglia) syndrome

Association of Hypomagnesaemia & Hypocalcemia with Intracerebral Hemorrhage and Outcome

Determine if hypomagnesemia & hypocalcemia on admission was associated with ICH and outcome. Magnesium is a vascular smooth muscle relaxant and appears to provide protection against cellular injury in experimental stroke models. The implication of low serum magnesium in primary ICH is not well defined. All patients with a primary ICH presented to PIMS, Islamabad prospectively analyzed in a pilot study. Demographics, initial lab values, ICH location, Mg+2 level, NIHSS & MRS at presentation were recorded. All patients with INR \u3c= 1.5 were included in this study. We took normal serum magnesium in our study was 1.8 - 2.5 mEq/dL. Statistical significance was determined using linear regression adjusting for admission systolic blood pressure (SBP). We identified 66 patients who met the inclusion criteria. The mean age was 52.76 years with minimum and maximum age was 25 and 80 years respectively. Total male and female patients were 40 (61%) and 26 (39.4%). The total number of patients with hypomagnesemia was 23 (30%) and with hypocalcemia was 54 (65%). All patients having hypomagnesemia (30%) also had subsequent hypocalcemia. Mean systolic Blood pressure (SBP) was 156.65 mmHg and 55patients (84.62%) presented with high SBP. All patients with hypomagnesemia presented with high SBP (p=0.001). Hypomagnesemia and hypocalcemia both were showed statically significant association with poor MRS & NIHSS score (p=0.013 and p=0.001). Hypomagnesemia was not showed statistically significant relation with the outcome (p=0.11) while hypocalcemia showed a remarkable association with outcome (p=0.001)

Demographic profile and associations of dialysis dependent chronic kidney disease patients in federal capital of pakistan.

Depression is quite prevalent in patients with chronic kidney disease. Knowing the frequency of depression in such patients and its association with different variables may be helpful in devising strategies for better and timely management of such patients in our setup. Materials and methods: This cross sectional study was conducted by recruiting 315 patients of either gender, ≥ 18 years of age with chronic kidney disease (CKD) and receiving care at Pakistan Institute of Medical Sciences, Islamabad. Patients were divided into two groups; group A: pre-dialysis and group B: dialysis (End Stage Renal Disease). Prevalence of depression in CKD and dialysis group and its association with gender, level of formal education and socioeconomic status was evaluated using descriptive statistics and chi-square test. Results: Out of 204 (100%) patients in group B, 171 (83.8%) patients had depression while in group A, 68 (61.3%) out of 111 (100%) patients were depressed. The prevalence of depression in all stages of CKD combined was 75.87 % (239 out of 315) and that in dialysis group was 83.82% (171 out of 204). Frequency of depression was significantly higher in the dialysis group (p=0.01). Those with higher level of education less commonly suffered from depression (p=0.01). No such association was found with gender (p=0.68) or socioeconomic status (p=0.12).Conclusion: Frequency of depression is significantly higher in dialysis dependent CKD patients with an overall prevalence of 75.87% in CKD and 83.82% in dialysis dependent ones. Higher level of formal education positively affects the outcome while gender and socioeconomic class have no significant association

Polyneuropathy associated with iga Paraproteinemia: a case report and literature Review.

Paraproteinemia is precipitated by an accumulation of monoclonal plasma cells or B lymphocytes. Idiopathic neuropathies that are associated with paraproteinemia account for only 10% of the neuropathies. Paraprotein acts like an antibody and is targeted against myelin and axons present in the peripheral nerves. Despite being of interest for quite a long time, the caudal relationship between paraproteinemias and peripheral neuropathies still remains a sorcery. We report a case of a middle aged male who presented with pain and parasthesias in both arms and legs. His workup revealed him to be having a paraproteinemic neuropathy consistent with IgA Lambda chains that account for being the most rare type of monoclonal gammopathy than IgM or IgG having the potential to progress to smouldering multiple myeloma

Measurement of transverse energy at midrapidity in Pb-Pb collisions at root s(NN)=2.76 TeV

We report the transverse energy (ET) measured with ALICE at midrapidity in Pb-Pb collisions at root s(NN) = 2.76 TeV as a function of centrality. The transverse energy was measured using identified single-particle tracks. The measurement was cross checked using the electromagnetic calorimeters and the transverse momentum distributions of identified particles previously reported by ALICE. The results are compared to theoretical models as well as to results from other experiments. The mean ET per unit pseudorapidity (eta), , in 0%-5% central collisions is 1737 +/- 6(stat.) +/- 97(sys.) GeV. We find a similar centrality dependence of the shape of as a function of the number of participating nucleons to that seen at lower energies. The growth in at the LHC energies exceeds extrapolations of low-energy data. We observe a nearly linear scaling of with the number of quark participants. With the canonical assumption of a 1 fm/c formation time, we estimate that the energy density in 0%-5% central Pb-Pb collisions at root s(NN) = 2.76 TeV is 12.3 +/- 1.0 GeV/fm(3) and that the energy density at the most central 80 fm(2) of the collision is at least 21.5 +/- 1.7 GeV/fm(3). This is roughly 2.3 times that observed in 0%-5% central Au-Au collisions at root s(NN) = 200 GeV.Peer reviewe
