A Survey on Malware detection using ML

This Malware detection is a field of computer security that deals with the study and prevention of malicious software. It is not the only way to defend a company against a cyber- attack. In order to be effective, companies should analyse their risk and identify the vulnerabilities. In this paper, we will examine different techniques used to detect computer malware and malicious websites as well as future directives in this area of study and also, we will discuss the growth in computer malware and how traditional methods of detection are being replaced by innovative techniques like behavioural-based model and Signature-based model. Future directives involve developing better security products in order to fight against cyber fraud which is on a rise in recent years especially in Asia Pacific region. With this increase in cyber frauds and other malicious activities, traditional methods are not enough to block computers from it as this method has many drawbacks. In order to tackle these issues, researchers have been developing new techniques such as heuristic analysis, static & dynamic analysis which can detect more than 90% of malware samples without any false positives or negatives. Keywords: Behaviour-based approach, Dynamic analysis, Heuristic, Malware, Ransomware, Signature-based model, Static analysis, Vulnerability.

Pioneering Evaluation of GaN Transistors in Geostationary Satellites

In this paper, we present the results of a 6-year experiment in space that studied the effects of radiation in GaN electronics in geostationary orbit. Four GaN transistors in a Colpitts oscillator configuration were flown in the Component Technology Test-Bed aboard the Alphasat telecommunication satellite. A heuristic analysis was performed by observing the variation in the power output of the oscillators with the total ionizing dose gathered during the mission. The total ionizing dose was measured with a RADFET placed close to the GaN devices. The experiment showed that GaN is a robust technology that can be used in the space radiation environment of a geostationary orbit. The work presented here starts with a brief introduction of the subject, the motivation and the main goal. This is followed by the description of the experimental setup, including the details of the oscillator design and simulations, as well as the implementation of the test bead and the Components Technology Test Bed. Finally, the results obtained during the 6 years of experience in space are discussed.

Divergent Views and Experiences Regarding ‘Completed Life’ and Euthanasia in the Netherlands

A small proportion of older people in the Netherlands want to end their lives because they feel their lives to be ‘completed’ and no longer worth living. Currently, there is heated debate over whether or not these people should have the right to euthanasia. Drawing on previous research, we conduct a heuristic analysis of views and experiences of three different ‘parties’ involved in this debate, namely, the older people, their relatives and friends and medical professionals. The views of these three groups tend to be divergent and conflicting, posing a difficult dilemma to decision-makers.

Atmosphere, private ordering, and industrial pluralism: Williamson's evolving science of organization

The major contribution of Oliver Williamson, who was a 2009 Nobel Prize co-Laureate in economics, consists of proposing a heuristic analysis of governance structures, namely, the firm, the market, and what he will later call the ‘hybrid forms’. This cardinal issue in organizational economics has made it possible to propose rigorous arbitration tools for the famous ‘make or buy’ decisions in modern market economies based on asset specificity and quasi-rents. However, Williamson's work goes far beyond these contributions alone. His contribution is based on a multidisciplinary theoretical background in building the science of organization. This is the important but sometimes neglected aspect of Williamson's work that I wish to highlight in this paper in memory of Williamson in regard to three major pieces on atmosphere (and informal organization), private ordering, and industrial pluralism. In doing so, I also propose reconsidering the different stages of Williamson's evolving science of organization from recent neo-institutional works.

Recovery of conformational continuum from single-particle cryo-EM data: Optimization of ManifoldEM informed by ground-truth studies

This work is based on the manifold-embedding approach to the study of biological molecules exhibiting conformational changes in a continuum. Previous studies established a workflow capable of reconstructing atomic-level structures in the conformational continuum from cryo-EM images so as to reveal the latent space of macromolecules undergoing multiple degrees of freedom. Here, we introduce a new approach that is informed by detailed heuristic analysis of manifolds formed by simulated heterogeneous cryo-EM datasets. These simulated models were generated with increasing complexity to account for multiple motions, state occupancies and CTF in a wide range of signal-to-noise ratios. Using these datasets as ground-truth, we provide detailed exposition of our findings using several conformational motions while exploring the available parameter space. Guided by these insights, we build a framework to leverage the high-dimensional geometric information obtained towards reconstituting the quasi-continuum of conformational states in the form of an energy landscape and respective 3D maps for all states therein. This framework offers substantial enhancements relative to previous work, for which a direct comparison of outputs has been provided.

Simulating and benchmarking neutron total scattering instrumentation from inception of events to reduced and fitted data

In the design and realization of modern neutron scattering instrumentation, particularly when designing beamline concepts from the ground up, it is desirable to fully benchmark against realistically simulated data. This is especially true for total scattering beamlines, where the future deliverable data is to be analysed in both reciprocal- and real-space representations, and needs must be carefully balanced to ensure sufficient range, resolution and flux of the instrument. An approach to optimize the design of neutron scattering instrumentation via a workflow including ray-tracing simulations, event-based data reduction, heuristic analysis and fitting against realistically simulated spectra is demonstrated here. The case of the DISCOVER beamline concept at the Spallation Neutron Source is used as an example. The results of the calculations are benchmarked through simulation of existing instrumentation and subsequent direct comparison with measured data. On the basis of the validated models, the ability to explore design characteristics for future beamline concepts or future instrument improvements is demonstrated through the examples of detector tube size and detector layout.

Validation of soil quality index in soil using bioindicator plant

Soils provide a broad set of vital ecosystem services and sustains the production of food and fibers, balancing the ecosystem. Thus, from the perspective of soil quality, it is defined as an ability to balance within the ecosystem to sustain biological productivity, promoting the health of plants and animals, being evaluated by traditional indicators as physical, chemical and biological indicators, so the present work aims to estimate the soil quality index using multivariate models using soil biological attributes and validation with growth variables of the bioindicator plant. The study was developed in the agricultural area in P. Prudente, SP, the points collected were georeferenced, collections in depth of 0 -20 cm, microbiological analysis, microbial carbon and nitrogen biomass, dehydrogenase, respiration and microbial coefficient, having a bioindicator plant curly lettuce (Lucy Brown) as a validator of the soil. The results were discovered using the PCA model for the identification of autos vectors and autos values, grouping and identifying their collinearities, linear regression, r-pearson validation and cluster heuristic analysis. The microbial attributes and the bioindicator plant discriminated the agricultural areas evaluated with establishment and validation of SQI. The metabolic coefficient and N of the microbial biomass dissipation of the highest covariance values by multivariate analysis. The reforestation area with native species (SQI0.782%) and the livestock crop integration system (SQI0.765%) were evaluated as areas with better soil quality
