Forensic and genetic characterizations of diverse southern Thai populations based on 15 autosomal STRs

Southern Thailand is home to various populations; the Moklen, Moken and Urak Lawoi’ sea nomads and Maniq negrito are the minority, while the southern Thai groups (Buddhist and Muslim) are the majority. Although previous studies have generated forensic STR dataset for major groups, such data of the southern Thai minority have not been included; here we generated a regional forensic database of southern Thailand. We newly genotyped common 15 autosomal STRs in 184 unrelated southern Thais, including all minorities and majorities. When combined with previously published data of major southern Thais, this provides a total of 334 southern Thai samples. The forensic parameter results show appropriate values for personal identification and paternity testing; the probability of excluding paternity is 0.99999622, and the combined discrimination power is 0.999999999999999. Probably driven by genetic drift and/or isolation with small census size, we found genetic distinction of the Maniq and sea nomads from the major groups, which were closer to the Malay and central Thais than the other Thai groups. The allelic frequency results can strength the regional forensic database in southern Thailand and also provide useful information for anthropological perspective.

Deep Learning Based Multi-Modal Biometric Security System Using Visible Light Communication

Multi-biometric system is an advanced technology which has a wide application space in the field of information security. This work proposes the design of a personal identification system based on a combination of biometric inputs such as face, finger vein, iris and fingerprint. Viola jones algorithm is used for face detection. Convolutional neural network (CNN) with different optimisers are used to steeply raise the image texture and extract high definition distinct features of the input images. The deep dream image algorithm accompanies CNN by visualizing these images and by highlighting the image features learnt by the network. These images are used for understanding and diagnosing network behaviour. This network obtains a high recognition rate, which proves to be better performing than traditional algorithms. In addition to these, a high-speed advanced wireless communication technology (Li-Fi) is used in combination with GSM which would act as an alert system that effectively helps in notifying the supervisory authority, if the system is being trespassed without proper authentication.

The Effects of Cranial Orientation on Forensic Frontal Sinus Identification as Assessed by Outline Analyses

The utility of frontal sinuses for personal identification is widely recognized, but potential factors affecting its reliability remain uncertain. Deviations in cranial position between antemortem and postmortem radiographs may affect sinus appearance. This study investigates how slight deviations in orientations affect sinus size and outline shape and potentially impact identification. Frontal sinus models were created from CT scans of 21 individuals and digitally oriented to represent three clinically relevant radiographic views. From each standard view, model orientations were deviated at 5° intervals in horizontal, vertical, and diagonal (e.g., left-up) directions (27 orientations per individual). For each orientation, sinus dimensions were obtained, and outline shape was assessed by elliptical Fourier analyses and principal component (PC) analyses. Wilcoxon sign rank tests indicated that sinus breadth remained relatively stable (p > 0.05), while sinus height was significantly affected with vertical deviations (p < 0.006). Mann–Whitney U tests on Euclidean distances from the PC scores indicated consistently lower intra- versus inter-individual distances (p < 0.05). Two of the three orientations maintained perfect (100%) outline identification matches, while the third had a 98% match rate. Smaller and/or discontinuous sinuses were most problematic, and although match rates are high, practitioners should be aware of possible alterations in sinus variables when conducting frontal sinus identifications.

Semantic modelling of self-realization of the personality

Introduction. The research is focused on studying self-organization of the personality in aspect of subjectness. The technique of modeling of social and role identification of the personality is presented. The research objective - to define semantic constructs self-updating in modeling of personal identification. Methods and techniques.- Semantic approach in structuring dichotomizing couples of constructs of personal identification is used. Offered original technique "Semantic Modelling of Self-organization of the Personality" ("SMSOP"). Respondents fill "Repertoire lattices" of J. Kelly. Results of sample are factorized. Respondents make modeling of in images "I am-real", "I am-ideal" and also images of "The Self-updated Personality" (SUP) and "Nonconformist" (NC), using a set of the linguistic constructs received by means of repertoire lattices of J. Kelly). The participants are 218 psychology students. Results and discussion. Comparative data of self-renewing constructs (in the aspect of "I-ideal") and the SUP and Oil Company models are shown. Although soup is a reference model of personality achievements (according to A. Maslow et al.), a NK reveals the properties of self-affirmation, In the semantics of mental self-organization (MSS) of a personality, respondents are not fully focused on these standards. The results of the factor analysis showed the peculiarities of the semantics of the students' personality MCO in the aspect of self-renewal ("I-ideal"): emotional spontaneity and, at the same time, fortitude and self-confidence, as well as communication and well-being in life (associated with intelligence, ingenuity). Conclusions.- The semantics of self-renewing personalities is revealed to young people in positions that determine the possible, achievable aspects of the perspective of their life. The SUP and NC models are "perfect" for them. Introducción.- La investigación está orientada hacia el estudio de la autoorganización de la persona en el aspecto de la subjetividad. Se presentada la técnica de la modelización social y de la identificación de rol de la personalidad. El objetivo de la investigación consiste en definir el constructo de la autoactualización en la modelización de la identificación personal. Métodos y técnicas.- Se usa un enfoque semántico en la estructuración dicomotizada de pares de constructos de identificación personal. Se aporta una técnica original de "Modelización semántica de auto-organización de la personalidad" (MSAOP). Los entrevistados rellenan «las rejillas de repertorio» de J. Kelly. Resultados de la muestra fueron factorizados. Los entrevistados hacen la modelización en imágenes "Yo-real", "Yo-ideal", y también imágenes «de la personalidad autoactualizada» (PAA) y "Noconformista" (NC), usando un conjunto de constructos recogidos del repertorio de rejillas de J. Kelly). La muestra consta de 218 estudiantes de psicología. Resultados y discusión.- Se muestran datos comparativos de constructos autoactualizables (en el aspecto de "Io-ideal") y los modelos SUP y Oil Company. Aunque el SUP es un modelo de referencia de los logros de la personalidad (según A. Maslow et al.), Un no-conformista revela las propiedades de la autoafirmación. En la semántica de la autoorganización mental (MSS) de la personalidad, los encuestados no están completamente enfocados hacia estos estándares. Los resultados del análisis factorial mostraron las peculiaridades de la semántica de la personalidad de los estudiantes MCO en el aspecto de la autoactualización ("yo-ideal"): espontaneidad emocional y, al mismo tiempo, fortaleza y autoconfianza, así como como comunicación y bienestar en la vida (asociado a la inteligencia, e ingenuidad). Conclusiones.- La semántica de las personalidades autoactualizadas se revela a los jóvenes en posiciones que determinan los aspectos posibles y alcanzables de sus perspectivas de vida. Los modelos SUP y NC son "perfectos" para ellos.

Generating Synthetic Disguised Faces with Cycle-Consistency Loss and an Automated Filtering Algorithm

Applications for facial recognition have eased the process of personal identification. However, there are increasing concerns about the performance of these systems against the challenges of presentation attacks, spoofing, and disguises. One of the reasons for the lack of a robustness of facial recognition algorithms in these challenges is the limited amount of suitable training data. This lack of training data can be addressed by creating a database with the subjects having several disguises, but this is an expensive process. Another approach is to use generative adversarial networks to synthesize facial images with the required disguise add-ons. In this paper, we present a synthetic disguised face database for the training and evaluation of robust facial recognition algorithms. Furthermore, we present a methodology for generating synthetic facial images for the desired disguise add-ons. Cycle-consistency loss is used to generate facial images with disguises, e.g., fake beards, makeup, and glasses, from normal face images. Additionally, an automated filtering scheme is presented for automated data filtering from the synthesized faces. Finally, facial recognition experiments are performed on the proposed synthetic data to show the efficacy of the proposed methodology and the presented database. Training on the proposed database achieves an improvement in the rank-1 recognition rate (68.3%), over a model trained on the original nondisguised face images.

The Functional Purpose of Slang (Based on Russian and American Slangisms)

The purpose of this article was to identify the specific functions of slang from the standpoint of demonstrativeness, corporatism, and individual creative self-expression. The methods of comparative and cultural analysis were used. As a result, the following specific functions of slang were singled out: demonstrative, corporate, and the function of creative self-expression. Personal identification and social relationships determine the demonstrative function of slang, which is more pronounced in the speech of young people. Slangisms are distinguished by their vividness and imagery, which is caused by the desire of the individual to attract people’s attention and stand out from the crowd. At the same time, the opposition of slang to the established order can have a negative effect, when used ostentatiously. The corporate function of slang is fulfilled by indicating one’s belonging to a certain professional community and asserting one’s right to be considered as “one of us”. Ignorance of special slang hinders a person from fully functioning within a certain “corporation”. The abundance of slang synonyms, as well as the presence of whole sentences and phraseological units in slang, testifies to the creative potential of their inventors. This article provides examples of American and Russian slang units used in various semantic fields, as well as examples of slang homonymy. Comparison of stylistic synonyms confirms the fact that slangisms differ from their neutral and bookish equivalents due to their metaphorical as well as emotional and evaluative nature. The results of the study allow us to conclude that slang has much in common with folk art, in which the changing value orientations of modern society are manifested. We also found that slang holds a dominant position in the framework of non-standard lexicon. Due to the continuous evolution, slang is a rather volatile phenomenon that allows new words and expressions to quickly enter the vocabulary.
