Socialbots and the Challenges of Cyberspace Awareness

As security communities brace for the emerging social automation based threats, we examine the mechanisms of developing situation awareness in cyberspace and the governance issues that socialbots bring into this existing paradigm of cyber situation awareness. We point out that an organisation's situation awareness in cyberspace is a phenomena fundamentally distinct from the original conception of situation awareness, requiring continuous data exchange and knowledge management where the standard implementation mechanisms require significant policy attention in light of threats like malicious social automation. We conceptualise Cyberspace Awareness as a socio-technical phenomena with Syntactic, Semantic, and Operatic dimensions - each subject to a number of stressors which are exacerbated under social automation based threats. The paper contributes to the ideas of situational awareness in cyberspace, and characterises the challenges therein around tackling the increasingly social and often pervasive, automation in cyber threat environments

Rare Occurrence of Four Rooted Maxillary Third Molar: A Case Report

This case report presents a rare variant of maxillary third molar variant, which had four roots. A 48-year-old male patient complained about severe pain in his left maxillary tooth region of the jaw. A clinical intraoral inspection and radiography were carried out on the tooth, and a diagnosis of chronic apical periodontitis was made. An uneventful extraction was performed for the same

A Joint 3D-2D based Method for Free Space Detection on Roads

In this paper, we address the problem of road segmentation and free space detection in the context of autonomous driving. Traditional methods either use 3-dimensional (3D) cues such as point clouds obtained from LIDAR, RADAR or stereo cameras or 2-dimensional (2D) cues such as lane markings, road boundaries and object detection. Typical 3D point clouds do not have enough resolution to detect fine differences in heights such as between road and pavement. Image based 2D cues fail when encountering uneven road textures such as due to shadows, potholes, lane markings or road restoration. We propose a novel free road space detection technique combining both 2D and 3D cues. In particular, we use CNN based road segmentation from 2D images and plane/box fitting on sparse depth data obtained from SLAM as priors to formulate an energy minimization using conditional random field (CRF), for road pixels classification. While the CNN learns the road texture and is unaffected by depth boundaries, the 3D information helps in overcoming texture based classification failures. Finally, we use the obtained road segmentation with the 3D depth data from monocular SLAM to detect the free space for the navigation purposes. Our experiments on KITTI odometry dataset, Camvid dataset, as well as videos captured by us, validate the superiority of the proposed approach over the state of the art.Comment: Accepted for publication at IEEE WACV 201

A Study to Assess Career Satisfaction among Dental Practitioners in Kanpur City, U.P., India

BACKGROUND: For almost every health worker, job satisfaction is an important determinant for motivation, retention and performance, and all of these are primarily important to improve the functioning mechanism of health systems in countries of low- and middle income categories.  AIM: This study was conducted to estimate the level of job satisfaction among registered practicing clinical dentists in Kanpur city, U.P., India MATERIALS & METHOD:  A cross sectional study was conducted among 204 practicing registered dentists. A questionnaire was distributed manually to the participating dentists for measuring dimensions of job satisfaction. A 5 point Likert format with a score range from 1(described as strongly dissatisfied) to 4(described as strongly satisfied) was used to describe the items.  Analysis of data was analyzed using SPSS software 21.0 and student t test was applied for measuring the difference of means between the subgroups for each dimension. RESULTS: A significant difference (p<0.005) in levels of satisfaction for various dimensions of job satisfaction within gender, educational qualification and work status was found on analysis. The postgraduates were found to be more satisfied as compared to graduates with a difference in job satisfaction level between genders which was related to the personal time dimension. It was also derived from the study that dentists working full time expressed dissatisfaction in terms of family time, thus to issues in their personal relationships. CONCLUSION:  Overall, it was found that the dentists have a high level of job satisfaction and the socio demographic factors deeply influence this domain of career

Exposing Nipah virus: an epidemiological study of another thread in Kerala, South India

Bats spread the Nipah virus, which causes severe encephalitis and high mortality. Multiple reports have come from Malaysia, Bangladesh, Singapore, and India. Pteropus fruit bats are known to host the virus. The virus has caused four outbreaks in Kerala in the past quinquennium. Scholars believe the virus is indigenous to the state's bat population. Climate change, resource depletion, deforestation, natural terrain changes, farming, and industrialization all contribute to viral disease outbreaks. In this review, we will discuss the epidemiological background of the previous NiV outbreak. We will also examine the transmission method epidemic prevention and control strategies and possible causes of the outbreak. Four Nipah epidemics have occurred in Kerala in the past five years. Expert investigation suggests that the virus may be endemic in the state’s bat population. Kerala, India, has many bat species. In 2018, research found viral infections in the local fruit bat population. Traditionally, people eat fresh toddy or sap from trees, which can be polluted by bats carrying the Nipah virus. Kerala's healthcare system also closely monitors unexplained fevers for Nipah virus infections. The World Health Organisation and Indian Council of Medical Research found that the entire state is susceptible to Nipah virus infections. The virus is a major cause of encephalitis outbreaks, which have high mortality rates, mostly in Indo-Bangladesh

HELIANTHUS - SMART SOLAR PANEL

The paper outlines an application of smart solar “photovoltaic” power generation. Solar panels are typically in fixed position. They\u27re limited in their energy-generating ability because they cannot consistently take full advantage of maximum sunlight. For more effective solar energy system, the solar panel should be able to align with sunlight as it changes during a given day. The present paper examines the design advantages of creating an intelligent solar tracking system like a helianthus flower using microcontroller based embedded system

A rare case of cervical dysgenesis presented with endometriosis and ectopic kidney

Cervical dysgenesis is a rare cause of obstructive amenorrhoea. We are presenting a case of a 15-year-old girl presented with primary amenorrhoea diagnosed with cervical dysgenesis with left ectopic kidney and endometriosis. The patient underwent laparoscopy followed by exploratory laparotomy with total abdominal hysterectomy with left salpingectomy followed by neovaginal creation and right ureteric D-J stenting and vaginal mould insertion. Cervical agenesis treatment should aim at the re-establishment of patency of the outflow tract. A fistulous tract with stent placement has been done in some cases but eventually, hysterectomy is required in view of recurrent and severe pelvic infection is a common problem. Ovarian function can be preserved if a hysterectomy is performed timely

Potency test of a rape accused in India – Rationale, problems and suggestions in light of the Criminal Law (Amendment) Act, 2013

AbstractIndian legal system makes it mandatory to medically examine any accused of rape as well as other forms of sexual assault. Accused is brought in the police custody for conducting medical examination which includes general physical examination, potency test and evidence collection. The medical examination report of the accused is labeled as the “POTENCY TEST REPORT”. As per the changed definition of rape after Criminal Law (Amendment) Act, 2013, potency test stands irrelevant in rape cases because the changed law does not require peno-vaginal intercourse to call it as rape. However, even after the change in definition of rape and laws related to it, potency test is still a mandatory part of medical examination of accused. Displeasure about the same has also been raised by a fast track court of Delhi. In this paper, we have discussed the rationale of potency test of sexual assault in light of Criminal Law Amendment Act (2013), court judgment and other available literature
