Person Retrieval in Surveillance Using Textual Query: A Review

Recent advancement of research in biometrics, computer vision, and natural language processing has discovered opportunities for person retrieval from surveillance videos using textual query. The prime objective of a surveillance system is to locate a person using a description, e.g., a short woman with a pink t-shirt and white skirt carrying a black purse. She has brown hair. Such a description contains attributes like gender, height, type of clothing, colour of clothing, hair colour, and accessories. Such attributes are formally known as soft biometrics. They help bridge the semantic gap between a human description and a machine as a textual query contains the person’s soft biometric attributes. It is also not feasible to manually search through huge volumes of surveillance footage to retrieve a specific person. Hence, automatic person retrieval using vision and language-based algorithms is becoming popular. In comparison to other state-of-the-art reviews, the contribution of the paper is as follows: 1. Recommends most discriminative soft biometrics for specific challenging conditions. 2. Integrates benchmark datasets and retrieval methods for objective performance evaluation. 3. A complete snapshot of techniques based on features, classifiers, number of soft biometric attributes, type of the deep neural networks, and performance measures. 4. The comprehensive coverage of person retrieval from handcrafted features based methods to end-to-end approaches based on natural language description.

A rare case of Hermansky-Pudlak Syndrome with bruise and mellitus diabetes

Albinism is a hereditary disorder that causes decreased pigmentation (coloring) in the body. As a consequence, albinism individuals are mostly fair-skinned with light hair known as oculocutaneous albinism. Skin, hair and color of the eye may vary, however, as some people with albinism may have dark brown hair and green or hazel / blue eyes. In both cases, poor vision and varying degrees of nystagmus (uncontrolled side-to-side eye movements) are observed. Everyone with HPS has albinism but not all people with albinism have HPS. We recorded a case with multiple comorbidities of a 37-year-old female patient with Hermansky-Pudlak syndrome (HPS) here

Some Remarks on the Ambiguous Portrayal of Olaf Haraldsson in Snorri Sturluson’s Narrative

Olaf Haraldsson (Saint Olaf) made history as a king and missionary but also as one of the forefathers and patron saints of Christian Norway. His achievements have perpetuated in the folk memory of the Scandinavian peoples, making him the Eternal King of Norway (Rex Perpetuus Norvegiae) and the most distinguished figure among those Norwegian rulers whose reigns are recorded in sagas. Nevertheless, Olaf, though a saint, is depicted as a bellicose, harsh, and severely punishing ruler – a picture that seems to diverge significantly from the model of a gentle, merciful, and saintly king, widespread in the European hagiographic tradition. That twofold nature of Olaf is described in Snorri Sturluson’s narrative, as indicated earlier by Carl Phelpstead. The present study refers to the findings of that scholar and emphasizes two interrelated facets of Olaf’s picture in Snorri’s narrative: his childhood and his appearance. In the former case, Olaf is shown as a naughty child, disrespecting his stepfather, which corresponds to the posterior episode of Olaf’s return to Norway, depicted as a paraphrase of the Parable of the Prodigal Son. Snorri provides a picture of a young man who, unlike the prodigal son, fails to change his faulty nature, and that in turn influences the way he rules. In the latter case, while depicting Olaf’s appearance, Snorri seems to present his looks only partially. Although Olaf is handsome, well-built, and his face and hair have a fair shade, he is short, has a flushed face and brown hair. In this way, Snorri departs from the model of a tall ruler with a fair complexion and blond hair. However, if we take into account the older Legendary Saga, it seems that Snorri in both cases follows solutions that are deeply rooted in the oral and written tradition, and which are supposed to reflect the ambiguity characterizing the memories of Olaf kept by the peoples of Scandinavia in the generations living after his death.

Does Eumelanin Oxidation Play a Role on the Photostability of Ethyl Glucuronide in Hair Exposed to Simulated Solar Radiation?

The action of solar radiation on the concentration of the ethanol metabolite ethyl glucuronide (EtG) in 40 hair samples of nonabstinent subjects was investigated. Hair samples of different colors were analyzed before and after irradiation with artificial sunlight under a light dose corresponding to 3 months of sun exposure. After irradiation, an increase of EtG concentration was detected in 55% of the samples ranging from 5% to 141%. In 16 cases, a concentration reduction ranging from −2% to −74% was observed. The measure of the level of pyrrole-2,3,5-tricarboxylic acid (PTCA), a marker of eumelanin oxidation, demonstrated the largest increase in oxidation in light brown hair where the greatest degradation of EtG was observed after irradiation. However, the rise of PTCA in all hair tested was accompanied by increase in EtG concentration in 8/10 samples and by decrease in 2/10, suggesting no correlation between the two markers. To verify if hair structure was modified by light, scanning electron microscopy (SEM) analysis was performed on irradiated hair of different colors and compared with the dark samples. SEM revealed modification of hair structure in all samples showing partial shaft exfoliation and reduction of hair thickness under the treatment with solar radiation.

LAPORAN KASUS : PENANGANAN TRANSMISSIBLE VENEREAL TUMOR PADA ANJING LOKAL DI ANOM VET CLINIC

Transmissible venereal tumor is a tumor that generally infects male and female genitalia and transmission occurs due to marriage and licking. On August 7th , 2019 the owner came with complaints of fresh blood dripping continuously from the vulva of Unyil, a local dog, female, approximately 3 years old, brown hair color, with a weight of 10.2 kg. After a physical examination in the perineal area, there is a mass like grapes formed in the vagina. Based on the results of physical examination and haematology test, the dog was diagnosed with transmissible venereal tumor. Handling is done in this case by removing the mass such as grapes formed in the vagina through surgery.

A 5700 year-old human genome and oral microbiome from chewed birch pitch

The rise of ancient genomics has revolutionised our understanding of human prehistory but this work depends on the availability of suitable samples. Here we present a complete ancient human genome and oral microbiome sequenced from a 5700 year-old piece of chewed birch pitch from Denmark. We sequence the human genome to an average depth of 2.3× and find that the individual who chewed the pitch was female and that she was genetically more closely related to western hunter-gatherers from mainland Europe than hunter-gatherers from central Scandinavia. We also find that she likely had dark skin, dark brown hair and blue eyes. In addition, we identify DNA fragments from several bacterial and viral taxa, including Epstein-Barr virus, as well as animal and plant DNA, which may have derived from a recent meal. The results highlight the potential of chewed birch pitch as a source of ancient DNA.

SPECIFIC CHARACTERISTICS OF ELECTRON PARAMAGNETIC RESONANCE SPECTRUM OF DIFFERENT COLORS OF HAIR

In the result of interaction of the metabolic processes of the human organism and external factors free radicals are formed in tissues including hair. An objective assessment of an intensity of this process is possible by means of electronic paramagnetic resonance’s (EPR) signal and its intensity indices. The purpose of the survey was a comparative evaluation of the EPR spectrum’s specificity of black and brown hair and a study of a photo dynamic in the condition of a treating with blue light. The survey was conducted among young volunteers of age 17-21 on the base of their informed consent and with adherence of all bioethical requirements established for this type of research. No single person’s hair involved in the survey was treated with chemical dye or active, specific remedy for hair care. This article analyzes data of young men donors. All measurements were carried out at standard conditions: room temperature (22-240C), humidity - 60-70%, the measurement error - ± 5%. EPR spectrum was determined at the Department of Biophysics,TSU by means of a radio-spectrometer TSR - V. Study results have determined a uniform EPR spectrum and no difference in the intensity of the photoinduced EPR spectrum that indicates the equal concentrations of eumelanin in black and brown hair.

Lentivirus Susceptibility in Iranian and German Sheep Assessed by Determination of TMEM154 E35K

Small ruminant lentiviruses (SRLVs) cause maedi-visna disease in sheep and are prevalent in Iran and Germany. The association of the transmembrane protein 154 (TMEM154) variants with SRLV infection has been previously identified by a genome-wide association (GWAS) approach and subsequent analyses, and validated in some US, German, and Turkish sheep flocks. We aimed at evaluating these findings for the first time in Iranian, and in some more German sheep flocks/breeds. Also, we aimed at comparing the SRLV susceptibility in Iranian and German sheep based on the frequency of the TMEM154 E35 allele. About 800 blood samples were collected from 21 Iranian and German sheep flocks/breeds for different purposes: (1) The association of TMEM154 E35K with SRLV infection status was tested in four sheep breeds and found to be significant in Kermani, Merinoland, and Brown Hair. (2) The usefulness of the TMEM154 E35 frequency for predicting SRLV susceptibility was evaluated by regression analysis, combining data from this study and some already published data. Results showed a significant association between E35 frequency and SRLV prevalence. (3) SRLV susceptibility was compared based on E35 frequency in Iranian and German sheep. Altogether, findings of this study provide valuable information on SRLV susceptibility, using TMEM154 E35, in Iranian and German sheep.
