Movies Tags Extraction Using Deep Learning

Retrieving information from movies is becoming increasingly demanding due to the enormous amount of multimedia data generated each day. Not only it helps in efficient search, archiving and classification of movies, but is also instrumental in content censorship and recommendation systems. Extracting key information from a movie and summarizing it in a few tags which best describe the movie presents a dedicated challenge and requires an intelligent approach to automatically analyze the movie. In this paper, we formulate movies tags extraction problem as a machine learning classification problem and train a Convolution Neural Network (CNN) on a carefully constructed tag vocabulary. Our proposed technique first extracts key frames from a movie and applies the trained classifier on the key frames. The predictions from the classifier are assigned scores and are filtered based on their relative strengths to generate a compact set of most relevant key tags. We performed a rigorous subjective evaluation of our proposed technique for a wide variety of movies with different experiments. The evaluation results presented in this paper demonstrate that our proposed approach can efficiently extract the key tags of a movie with a good accuracy

N,N′-Bis(3-methylbut-2-enyl)-N,N′-(1,4-phenylene)dibenzenesulfonamide

The complete mol­ecule of the title compound, C28H32N2O4S2, is generated by a crystallographic inversion centre. The dihedral angle between the central and pendant aromatic rings is 46.78 (7)°. The Car—S—N—Car (ar = aromatic) torsion angle is 73.64 (15)° and the bond-angle sum for the N atom is 350.4°. In the crystal, weak C—H⋯O inter­actions link the mol­ecules, forming a two-dimensional network lying parallel to the bc plane

2,2′,5,5′-Tetra­chloro-N,N′-diethyl-N,N′-[benzene-1,3-diylbis(methyl­ene)]dibenzene­sulfonamide

In the title compound, C24H24Cl4N2O4S2, the dihedral angles between the central benzene ring and the pendant rings are 58.09 (10) and 62.59 (10)°. The dihedral angle between the pendant rings is 81.64 (9)°.

In the title compound, C26H24Cl4N2O4S2, the dihedral angles between the central benzene ring and the pendant rings are 70.07 (12) and 59.07 (12)°. The equivalent angle between the pendant rings is 79.24 (12)°. Both sulfonamide groups lie to the same side of the central ring but the pendant chains have very different conformations, as indicated by their C—S—N—C torsion angles [104.66 (17) and −76.35 (19)°] and S—N—C—C torsion angles [129.61 (17) and 147.10 (17)°]. Both N atoms are close to planar (bond angle sums = 359.0 and 354.8°). In the crystal, inversion dimers are formed via a pair of weak C—H⋯O inter­actions which generate R 2 2(22) loops

Bis(cyanido-κC)bis­(cyclo­hexyl­amine-κN)mercury(II)

In the title compound, [Hg(CN)2(C6H13N)2], the HgII ion adopts an extremely distorted HgC2N2 tetra­hedral coordination. The crystal packing is influenced by weak N—H⋯N hydrogen bonds between the amino groups and the cyanide N atoms, resulting in chains of mol­ecules propagating in [110]. Both cyclo­hexyl­amine mol­ecules adopt chair conformations

Hallervorden spatz disease – a rare clinicoradiological diagnosis

Hallervorden Spatz disease, also known as pantothenate kinase associated neuro-degeneration, is a rare, progressive neurological disorder usually seen in first decade of life. It is associated with extrapyramidal effects, dysarthria and dementia. Hallervorden Spatz Disease is also associated with psychiatric symptoms, depression and behavioral changes. Affected patients are disabled predominantly by dystonia. MRI, in later stage of the disease, shows “eye of the tiger’ appearance which is fairly diagnostic of Hallervorden Spatz Disease. Response to drugs is often poor and of limited value to these patients. This report highlights a classical case of Hallervorden Spatz disease that presented as an outpatient with dystonia and psychotic symptoms and was diagnosed on the basis of clinical and radiological evidence

N,N′-[1,3-Phenyl­enebis(methyl­ene)]di-p-toluenesulfonamide

In the title compound, C22H24N2O4S2, the dihedral angles between the central benzene ring and the pendant rings are 66.96 (13) and 69.37 (13)°. The torsion angles for the C—N—S—C fragments are −68.5 (3) and −72.6 (3)°. In the crystal, mol­ecules are linked by N—H⋯O hydrogen bonds to generate infinite (001) sheets containing R 4 4(28) loops. A weak aromatic π–π stacking contact between one of the terminal benzene rings and its inversion-related partner is also observed [centroid-to-centroid separation = 3.796 (2) Å and slippage = 1.581 Å], as are two possible C—H⋯π contacts

Antibacterial Potentials of Human Urine at Acidic pH 5

To identify factors determining susceptibility of individuals to urinary tract infections (UTIs).Methods: In this descriptive study , 55 hospitalized patients' urine samples were analyzed. Presence of red blood cells , pus cells, epithelial cells, casts and crystals were observed and counted under per high power field (HPF) by microscopy. While pH, specific gravity, protein, leukocytes, nitrites, glucose, ketones, urobilinogen, blood and bilirubin, were analyzed using dipstick method. All the samples were streaked on CLED agar for isolation of bacteria; and SDA for yeast.Results: Twenty urine samples were found culture positive, of which 15 were from females and 5 from males. Cultures were isolated and identified as E. coli (11), Enterococcus (4), Klebsiella (3), Pseudomonas (1) and yeast (1). Interestingly, organisms were mainly isolated from urine samples having pH >5.5. In all the culture positive samples, pus cells were >20-40 /HPF. No patient with culture negative had urine pH 6.5 or above in the present study.Conclusion: The probability of bacteriuria (UTI) and pyuria (increase pus cells in urine) increases with rise in urine pH. Persons with urine pH5 are generally protected from UTIs. Thus mechanism/s needs to be elucidated

The complete mol­ecule of the title compound, C17H22N2O4S2, is generated by crystallographic twofold symmetry, with one C atom lying on the rotation axis. The dihedral angle between the benzene rings is 44.04 (7)° and the conformation of the central N—C—C—C group is gauche. In the crystal, mol­ecules are linked by N—H⋯O hydrogen bonds, generating corrugated (010) sheets, and weak C—H⋯O inter­actions consolidate the packing

El diagnóstico de tuberculosis en niños: el necesario aumento de mejores métodos

En el pasado decenio la tuberculosis (TB) ha reemergido como un peligro importante para la salud pública alrededor del mundo con una incidencia creciente entre adultos y niños. Aunque los casos entre niños representan un porcentaje pequeño de todo los casos de TB, los infectados son un reservorio de los cuales provendrán muchos casos de adultos. Al diagnóstico de la TB en niños comúnmente le sigue el descubrimiento de un caso adulto, y se basa en la prueba de la tuberculina en piel, radiografía de tórax y síntomas y signos clínicos. Sin embargo, los síntomas clínicos son inespecíficos, la radiografía de tórax y la prueba en piel pueden ser difíciles de interpretar y las pruebas de laboratorio de rutina no son útiles. Aunque las pruebas de laboratorio más rápidas y sensibles que tiene en cuenta los adelantos recientes en biología molecular, inmunología y cromatografía están siendo desarrollados, los resultados para los niños han desilusionado. Las mejores técnicas beneficiarían especialmente a niños e infantes en quienes el diagnóstico temprano es imperioso para prevenir la TB progresiva.Facultad de Ciencias Veterinaria
