Drone-based electromagnetic survey system for geophysical applications

Geophysical electromagnetic (EM) methods are used in geological mapping, mineral exploration, groundwater studies and geotechnical investigations. Airborne EM methods have the benefit of avoiding terrain obstacles such as lakes, rivers, swamps, and ravines. Compared to manned aircrafts, drones or unmanned aerial vehicles (UAVs) have benefits of their own. Drone-based surveys are versatile, fast to deploy, economical and ecologically more friendly. Presently, magnetic surveying is the only geophysical method that is routinely conducted with drones. The modest maximum payload limit of drones imposes severe restrictions on the applicability of other methods including EM and radiometric methods, for example. Finnish company, Radai Ltd has been developing Louhi, a novel drone-based frequency-domain EM survey system, in an EU funded Horizon 2020 project NEXT – New Exploration Technologies. The EM system has two operation options – the first uses a large loop on the ground as an EM source and the other uses a small portable EM transmitter loop. Both systems utilize a stand-alone and light-weight three-component EM receiver that can be towed by a drone. This article presents the theoretical background of the EM methods, the solution developed by Radai Ltd, the current version of the EM device, and results from field and flight tests that demonstrate the applicability of the drone-based EM system under development.

Design and usability assessment of DocManS: A document management system with security and social media features

A document management system (DMS) is required to handle any documents within an institution efficiently. However, several important features are lacking in the current DMS, such as security and social media features. This paper proposes a new solution to tackle the issues by developing a new document management system with security and social media features called DocManS. The development process and usability evaluation by users are presented in this paper. The usability assessment is performed with the use of the System Usability Scale (SUS) framework. The results show that the current version falls within the B range of the SUS framework and several enhancements for better usability in terms of social media sharing and privacy are recommended.

Automation of the development of ontologies of scientific subject domains based on ontology design patterns

At present, ontologies are recognized as the most effective means of formalizing and systematizing knowledge and data in scientific subject domains (SSDs). However, the development of an ontology is a rather complicated and time-consuming process. All indications are that when developing SSDs ontologies, it is especially effective to use ontology design patterns (ODPs). This is due to the fact that the SSD ontology, as a rule, contains a large number of typical frag-ments, which are well described by the ODPs. In addition, due to the fact that the use of ODPs greatly facilitates the development of an SSD ontology, it is possible to involve experts in a modeled SSD not possessing the skills of onto-logical modeling. To obtain an ontology that adequately describes the SSD, it is necessary to process a huge number of publications relevant to the modeled SSD. It is possible to facilitate and accelerate the process of populating the ontolo-gy with information from such sources by using the lexical and syntactic patterns of ontological design. The paper pre-sents an approach to the automated development of SSDs ontologies based on a system of heterogeneous ODPs. This system includes both ODPs intended for ontology developers and lexical and syntactic patterns built on the basis of the above-mentioned types of the ODPs and the current version of the SSD ontology.

The Scope of Rape Victimization and Perpetration Among National Samples of College Students Across 30 years

Research Questions: Rape prevention practice and policy have roots in data from 1985. This study uses 2015 national data to project recent prevalence, assesses whether rates now differ from those of 30 years ago, and disaggregates 2015 prevalence into rape of alcohol incapacitated victims, rapes combining both alcohol and physical tactics, and violent rape. Methods: Cross-sectional analyses were conducted comparing two national samples. The first was collected in 1984-85 (Koss, Gidycz, & Wisniewski, 1987); the second was collected 30 years later in 2014-2015. Both surveys used in-person administration and measurement by the most current version at the time of the Sexual Experiences Survey (SES). Prevalence rates were compared using Bayesian binomial tests. Results: In 2015, 33.4% (1 in 3) of women reported experiencing rape or attempted rape and 12.7% of men reported perpetration (1 in 8). Using Jeffreys' label for effect size of the Bayes binomial (1961), both results are “decisively” greater than expected given the 1985 benchmarks of 27.9% for victimization and 7.7% for perpetration. Victimization when incapacitated characterized approximately 75% of incidents in 2015 up from 50% in 1985. Cautions apply as cross-sectional data does not establish causality and the recent data set involved the revised SES. Conclusions: Across 30 years, neither containment nor reduction of rape was demonstrated and the increasingly prominent association with alcohol was apparent. Among the men who disclosed raping, 9 of 10 incidents were alcohol-involved. Prevention focus might profitably be directed to constraining alcohol environments and policies that facilitate rape of incapacitated persons and on misconduct responses that are proportional to the harm caused to rape victims, thereby raising the perceived risks of perpetration.

In the current version, information on COVID-19 as well as on selected topics of the labor market and demography are integrated. For this purpose, alternative cartographic representations have been developed, to visualize current topics at a glance. The aim of the atlas is to provide the public as well as decision makers with a tool to better assess current risk situations in Austria.

Rehabilitation organisch bedingter Gedächtnisstörungen: Was, wann, für welche Betroffenen?

The aim of this paper is to provide an overview of treatment strategies and methods as well as a practical decision support, based on the current version of the guideline on memory rehabilitation [55] and the authorsʼ views. We show that the choice of a method for efficient neuropsychological treatment depends on the type and severity of the memory disorder as well as on the previous therapy experience of the affected person and the defined therapy goal: e.g., what it means to work with implicit »errorless learning« methods; which form of external memory aids can be used with which patients; that methods for improving memory performance are available for persons with moderate to mild memory disorders; and that PC therapy is also likely to help younger and more mildly affected persons. The aim is also to provide a broad overview of current studies on memory rehabilitation, some with very promising results. However, many questions remain unanswered to date, some of which have been highlighted in this paper with the aim of stimulating future research to enable those affected by memory impairment to achieve the best possible rehabilitation and the greatest possible independence

Problems of realization of the principles of equality and competitiveness in the criminal process: possibility of their solution by implementation of the private detective institute in Ukraine

Introduction. The work considers the problem of implementation of private detective institute in the context of realization of the principles of equality and competitiveness in the criminal process. At present the relevancy of this institute is proved by numerous attempts of the Verkhovna Rada of Ukraine to adopt a relevant law. As scientists note, the current version of Draft Law contains a large number of shortcomings. At the same time, in Ukraine the problem of compliance of the provisions of the Code of the Criminal Process with the principles of equality and competitiveness in criminal proceedings remains controversial. Scientists have repeatedly studied this issue and suggested ways to solve them, but the corresponding changes have not yet been implemented. Such a solution is necessary to ensure respect for human rights, so it is important to consider the possibility of solving problems related to the implementation of the principles of equality and competitiveness through the introduction of the institution of private detective in Ukraine. The purpose of the paper is to examine the legal nature of the principles of equality and competitiveness in criminal proceedings, their interrelation, implementation problems, as well as the possibility of solving problems of implementation of these principles by introducing the institution of private detective in Ukraine. Results. Authors made an analysis of legislation, doctrine and international practice. It proved the importance of implementation of the institute of private detective. However, current Draft Law are not perfect and complete and cannot provide the improvement of realization of principles of equality and competitiveness in criminal proceedings. Conclusion. The position of Ukrainian criminal procedure law on compliance with principles of equality and competitiveness is not complete, as the defense has fewer opportunities to gather evidence than the prosecution represented by public authorities. To improve the situation with the principles of equality and competition, it is recommended to consider the introduction of the private detective institute in Ukraine. To do this, it is necessary to provide proper legislation in order for this institution to improve the situation in compliance with these principles.

The Multiple Sclerosis Data Alliance Catalogue

Background: One of the major objectives of the Multiple Sclerosis Data Alliance (MSDA) is to enable better discovery of multiple sclerosis (MS) real-world data (RWD). Methods: We implemented the MSDA Catalogue, which is available worldwide. The current version of the MSDA Catalogue collects descriptive information on governance, purpose, inclusion criteria, procedures for data quality control, and how and which data are collected, including the use of e-health technologies and data on collection of COVID-19 variables. The current cataloguing procedure is performed in several manual steps, securing an effective catalogue. Results: Herein we summarize the status of the MSDA Catalogue as of January 6, 2021. To date, 38 data sources across five continents are included in the MSDA Catalogue. These data sources differ in purpose, maturity, and variables collected, but this landscaping effort shows that there is substantial alignment on some domains. The MSDA Catalogue shows that personal data and basic disease data are the most collected categories of variables, whereas data on fatigue measurements and cognition scales are the least collected in MS registries/cohorts. Conclusions: The Web-based MSDA Catalogue provides strategic overview and allows authorized end users to browse metadata profiles of data cohorts and data sources. There are many existing and arising RWD sources in MS. Detailed cataloguing of MS RWD is a first and useful step toward reducing the time needed to discover MS RWD sets and promoting collaboration.

Study of theoretical luminosity precision for electron colliders at higher energies

We present an estimation of the theoretical precision of low angle Bhabha scattering at the proposed future ILC collider at 500 GeV. The analysis is an extension of the previous analysis done for the FCCee collider at $$\sqrt{s}=M_Z$$ s = M Z . As the state-of-the-art and the reference point we use the Monte Carlo event generator. Based on the current precision status of for LEP analysis, we estimate how various error components evolve from the LEP to ILC setups. The conclusion of our work is that for the ILC the precision of the current version of 4.04 deteriorates to 0.5%, by more than an order of magnitude w.r.t. the present precision for LEP. With the expected future improvements, the precision of can change to 0.016%, nearly as good as for the FCCee at the $$M_Z$$ M Z setup (0.01%). Based on the developed methodology we present also results for ILC$$_{1000}$$ 1000 , FCCee$$_{350}$$ 350 and CLIC$$_{3000}$$ 3000 setups.
