Multicostate zeillerids (Brachiopoda, Terebratulida) from the Lower Jurassic of the Eastern Subbetic (SE Spain) and their use in correlation and paleobiogeography

The Lower Jurassic multicostate zeillerids of the Subbetic Domain are described here for the first time. A new species (Fimbriothyris? dubari) is erected, and the affinities of the remaining three species are discussed. These taxa appear as part of an assemblage that includes several other brachiopods belonging to the Terebratulida, Rhynchonellida and Spiriferinida orders, which are specified. The correlation of this assemblage with others from neighbouring basins is attempted, with the aim to precise its chronostratigraphical position. A Sinemurian- Pliensbachian transition age is proposed. The spatial distribution of the Lower Jurassic multicostate zeillerids is analysed, revealing its strictly Mediterranean character, limited to some South-western Tethys areas. This allows discarding the supposed subboreal (northwest European) influences in the Subbetic faunas proposed by several authors. The relationship of this group of brachiopods with the initial stages of break-up and subsequent drowning of the Lower Jurassic carbonate platforms is also confirmed

Empirical study to fingerprint public malware analysis services

The evolution of malicious software (malware) analysis tools provided controlled, isolated, and virtual environments to analyze malware samples. Several services are found on the Internet that provide to users automatic system to analyze malware samples, as VirusTotal, Jotti, or ClamAV, to name a few. Unfortunately, malware is currently incorporating techniques to recognize execution onto a virtual or sandbox environment. When analysis environment is detected, malware behave as a benign application or even show no activity. In this work, we present an empirical study and characterization of automatic public malware analysis services. In particular, we consider 26 different services. We also show a set of features that allow to easily fingerprint these services as analysis environments. Finally, we propose a method to mitigate fingerprinting

Control climático, tectónico y eustático en depósitos del Carniense (Triásico Superior) del SE de la Península Ibérica

The Manuel Sandstone Formation or K2 from Ortí (1974) is a clastic intercalation in the middle of the Keuper facies of SE Spain. This formation corresponds to a low-stand systems tract (LST) and it can be subdivided into three minor cycles that can be traced all over the area here studied. Its age is late Cordevolian-early Julian (lower-middle Karnian) according to the palynomorphs that are found in several localities. A stratigraphical correlation of the formation from Alhambra (Ciudad Real) and Chiclana de Segura (Jaén) to Jaraco (Valencia) is shown, and the mutual influences of climate, tectonics and eustatism that controlled the lateral change from a classic Keuper facies from the E to a purely siliciclastic one to the Ware discussed

Optimal design of an LCC-S WPT3 Z1 SAE J2954 compliant system, using NSGA-II with nested genetic algorithms for simultaneous local optimization

Wireless Power Transfer (WPT) for electric vehicles is one of the most promising methods that, given its advantages, will drive the deployment of electric vehicles. This paper presents a mathematical optimization method applied to the complete design of an LCC-S WPT3 Z1 11 kW system that complies with the SAE J2954 standard (Wireless Power Transfer for Light-Duty Plug-in/Electric Vehicles and Alignment Methodology, 2020). A design method based on three phases is proposed, allowing the complete inductor system, including ferrites shielding and compensation circuit components, to function in any relative primary and secondary position. In Phase 1, a multi-objective NSGA-II algorithm is designed, utilizing three nested genetic algorithms. The goal is simultaneously searching for the local optimum between the primary and secondary systems in three positions. This is achieved by modeling the circuit’s electrical and electromagnetic parameters with equations, enabling an iterative process with reduced computational time. The NSGA-II algorithm yields three scenarios: primary copper volume minimization, secondary copper volume minimization, and a compromise solution that optimizes the total volume. The result is then modeled in Phase 2 using a 3D finite element program that includes ferrite and optimal shielding, obtaining the values of inductances and mutual inductance in the three positions, as well as design data for manufacturing. This result is introduced in Phase 3 to optimize compensation circuit components using a second NSGA-II algorithm with three nested genetic algorithms. Again, three scenarios are obtained based on the desired system behavior and the optimal cost of the components. The result is validated through simulation with Matlab-Simulink and experimentally using a prototype constructed for this purpose

Optimal design of a Low-Cost SAE JA2954 compliant WPT system using NSGA-II

Wireless Power Transfer (WPT) systems for electric vehicle charging are one of the most promising methods that, given the advantages they bring, will help the desired deployment of electric vehicles. This paper presents a mathematical optimisation method applied to the design of an 11 kW S-S system that complies with the SAE J2954 standard. A proposal is made to calculate the electrical parameters of the circuit based on equations that are compared with the results obtained by simulation with finite elements and experimental measurements, achieving very tight results with a reduced computational time. The NSGA-II multi-objective genetic algorithm is then applied together with the secant method, defining three different scenarios: minimisation of the primary copper volume, minimisation of the secondary copper volume and a compromise solution optimising the total primary and secondary copper volume. The result is a set of Pareto optimal solutions, from which the one that meets the standard can be extracted that suits the designer’s needs

Gravitational Radiation from Preheating with Many Fields

Parametric resonances provide a mechanism by which particles can be created just after inflation. Thus far, attention has focused on a single or many inflaton fields coupled to a single scalar field. However, generically we expect the inflaton to couple to many other relativistic degrees of freedom present in the early universe. Using simulations in an expanding Friedmann-Lema\^itre-Robertson-Walker spacetime, in this paper we show how preheating is affected by the addition of multiple fields coupled to the inflaton. We focus our attention on gravitational wave production--an important potential observational signature of the preheating stage. We find that preheating and its gravitational wave signature is robust to the coupling of the inflaton to more matter fields.Comment: 7 pages, 8 figures, v2 submission version, thank you for comments

The Differentiation and Promotion of Students’ Rights in Portugal

This investigation includes a differential study (Study 1) and a quasi-experimental research (Study 2). In Study 1, the objective was to establish to what extent students’ rights existed and analyse the differentiation between students’ rights with Portuguese and immigrant mothers, throughout school years. The sample consisted of 537 students with Portuguese and immigrant mothers, distributed by different school years (7th, 9th and 11th grades). The Children’s Rights Scale (Hart et al., 1996; Veiga, 2001) was used. In Study 2, the purpose was to analyse the effects on students’ rights of the use by teachers of a communicational intervention program, supervised by school psychologists. The sample involved 7th and 9th grade students, in a total of four classes, two forming the experimental groups (n = 36) and two the control groups (n = 43); as in Study 1, the Children’s Rights Scale was used. The results indicated the effectiveness of the communicational intervention program on students’ rights and are consistent with previous studies. An implication is that psychologists and teachers, working together and taking a human rights perspective, may develop an important role in projects to promote the students’ rights
