description: This article examines the technopolitics of prevention in postwar Guatemala. In the 2010s, experts and policymakers shifted security governance in Central America’s most populous country towards anticipation. Against the background of rising gang violence, they implemented a set of sociopolitical and techno-material measures – based on the latest crime-control technologies, new policing strategies and urban design methods – in Guatemala’s most violent municipalities. The stated goals were to reconstruct state sovereignty and to improve public security by strengthening community resilience and inducing positive behavioural change in ‘at-risk’ citizens. Zooming in on the case of Villa Nueva, the article examines the emergence and effects of Guatemala’s ‘prevention assemblage’. It demonstrates that this technopolitical project has failed, as prevention turned into a new layer of control that shifted responsibility to local communities, further securitized urban spaces and populations, and reproduced exclusionary and repressive security governance.

description: A key challenge in condensed matter research is the optimization of topological insulator (TI) compounds for the study and future application of their unique surface states. Truly insulating bulk states would allow the exploitation of predicted surface state properties, such as protection from backscattering, dissipationless spin-polarized currents, and the emergence of novel particles. Towards this end, major progress was recently made with the introduction of highly resistive Bi$_2$Te$_2$Se, in which surface state conductance and quantum oscillations are observed at low temperatures. Nevertheless, an unresolved and pivotal question remains: while room temperature ARPES studies reveal clear evidence of TI surface states, their observation in transport experiments is limited to low temperatures. A better understanding of this surface state suppression at elevated temperatures is of fundamental interest, and crucial for pushing the boundary of device applications towards room-temperature operation. In this work, we simultaneously measure TI bulk and surface states via temperature dependent optical spectroscopy, in conjunction with transport and ARPES measurements. We find evidence of coherent surface state transport at low temperatures, and propose that phonon mediated coupling between bulk and surface states suppresses surface conductance as temperature rises.

description: More than half of all fatalities on U.S. highways occur due to roadway departure (RwD) each year. Previous research has explored various risk factors that contribute to RwD crashes, however, a comprehensive investigation considering the effect of lighting conditions has been insufficiently addressed. Using the Louisiana Department of Transportation and Development crash database, fatal and injury RwD crashes occurring on rural two-lane (R2L) highways between 2008-2017 were analyzed based on daylight and dark (with/without streetlight). This research employed a safe system approach to explore meaningful complex interactions among multidimensional crash risk factors. To accomplish this, an unsupervised data mining algorithm association rules mining (ARM) was utilized. Based on the generated rules, the findings reveal several interesting crash patterns in the daylight, dark-with-streetlight, and dark-no-streetlight, emphasizing the importance of investigating RwD crash patterns depending on the lighting conditions. In daylight, fatal RwD crashes are associated with cloudy weather conditions, distracted drivers, standing water on the roadway, no seat belt use, and construction zones. In dark lighting conditions (with/without streetlight), the majority of the RwD crashes are associated with alcohol/drug involvement, young drivers (15-24 years), driver condition (e.g., inattentive, distracted, illness/fatigued/asleep) and colliding with animal (s). The findings reveal how certain driver behavior patterns are connected to RwD crashes, such as a strong association between alcohol/drug intoxication and no seat belt usage in the dark-no-streetlight condition. Based on the identified crash patterns and behavioral characteristics under different lighting conditions, the findings could aid researchers and safety specialists in developing the most effective RwD crash mitigation strategies.
‘One always looks for a compromise…’: Senior prison managers’ views of law, human rights and prisoner complaints in Germany

description: German prison legislation is based on a fundamental rights approach but there has been little examination of how those who should be instantiating a culture of rights in penal regimes – prison staff – view such laws and rights. This question is of cross-national importance. Holding considerable power over people in custody, examining the ways in which prison staff see and act on obligations to protect these individuals provides useful insights into how a culture of human rights in detention exists, or otherwise. In this article, we seek to contribute to the literature on human rights in the context of punishment by examining how senior staff in German prisons view legal regulation, prisoners’ rights, and the mechanism designed to protect them: complaints. Drawing on 24 interviews conducted in four prisons across two Federal States, we find that the principle of resocialisation, considered to be a core feature of German prison law, is influential on prison managers. German prison legislation links this principle to prisoners’ rights, including the right to complain. Managers valued the law as a form of guidance though were more positive about legal regulation when it was used by them rather than against them or the prison system. Some saw legal precepts as useful ways of defending themselves against threats of litigation or blame. While the study finds that law is highly present in prison manager culture in Germany, the principle of resocialisation in prison management practice may have created a view of prisoners as people to be in need, rather than worthy of rights.

description: Major advances in Question Answering technology were needed for IBM Watson to play Jeopardy! at championship level -- the show requires rapid-fire answers to challenging natural language questions, broad general knowledge, high precision, and accurate confidence estimates. In addition, Jeopardy! features four types of decision making carrying great strategic importance: (1) Daily Double wagering; (2) Final Jeopardy wagering; (3) selecting the next square when in control of the board; (4) deciding whether to attempt to answer, i.e., "buzz in." Using sophisticated strategies for these decisions, that properly account for the game state and future event probabilities, can significantly boost a players overall chances to win, when compared with simple "rule of thumb" strategies. This article presents our approach to developing Watsons game-playing strategies, comprising development of a faithful simulation model, and then using learning and Monte-Carlo methods within the simulator to optimize Watsons strategic decision-making. After giving a detailed description of each of our game-strategy algorithms, we then focus in particular on validating the accuracy of the simulators predictions, and documenting performance improvements using our methods. Quantitative performance benefits are shown with respect to both simple heuristic strategies, and actual human contestant performance in historical episodes. We further extend our analysis of human play to derive a number of valuable and counterintuitive examples illustrating how human contestants may improve their performance on the show.

description: The Framework for K-12 Science Education (July 2011) developed by the National Resource Council (NRC) draws on current scientific research and the ways students learn science effectively. This laid the foundation for Next Generation Science Standards (NGSS) released in Spring 2013. Tennessee was one of the 26 lead state partners to provide leadership to the standards writing team and to provide guidance as states deliberate on the adoption and implementation of the NGSS. We propose that the transition from current State science standards to NGSS demonstrates a extensive consensus on what all students should know and be able to do at specific K-12 grade levels and what topics can be postponed or excluded on the premise of developmental readiness. In order to facilitate this work, one of the STEM Fellows, Larry Bowman (author), created a series of 18 posters showing correlations between the current Tennessee Science Education standards (Huffman, 2009) and NGSS (Achieve, 2013). This article specifically addresses the NGSS Middle Grades Disciplinary Core Ideas (DCIs) as compared to the existing 6-8 Science Standards from the Tennessee Science Curriculum Framework. Some Grade Level Expectations (GLEs) for Middle Grades Science have been relocated to other grade levels, and others have been introduced. The term Middle Grades is used for students 10 to 15 years of age covering the critical years when children are transitioning from concrete operational to formal operational stages.

description: The subgroup commutativity degree of a group G has been defined in [6] as the probability that two subgroups of G commute, or equivalently that the product of two subgroups is again a subgroup. Problem 4.3 of [6] asks whether there exist families of groups other than dihedral, quasi-dihedral or generalized quaternion (all of 2-power cardinality), whose subgroup commutativity degree tends to 0 as the size of the group tends to infinity. An affirmative answer to this question has been provided by Aivazidis [1, 2] for the family of projective special linear groups over fields of even characteristic and for the family of the simple Suzuki groups. In this short note we indicate another family of groups with this property, namely the finite P-groups.
Modeling extreme values of processes observed at irregular time steps: Application to significant wave height

description: This work is motivated by the analysis of the extremal behavior of buoy and satellite data describing wave conditions in the North Atlantic Ocean. The available data sets consist of time series of significant wave height (Hs) with irregular time sampling. In such a situation, the usual statistical methods for analyzing extreme values cannot be used directly. The method proposed in this paper is an extension of the peaks over threshold (POT) method, where the distribution of a process above a high threshold is approximated by a max-stable process whose parameters are estimated by maximizing a composite likelihood function. The efficiency of the proposed method is assessed on an extensive set of simulated data. It is shown, in particular, that the method is able to describe the extremal behavior of several common time series models with regular or irregular time sampling. The method is then used to analyze Hs data in the North Atlantic Ocean. The results indicate that it is possible to derive realistic estimates of the extremal properties of Hs from satellite data, despite its complex space--time sampling.

Galaxy-wide outflows: cold gas and star formation at high speeds

description: Several active galaxies show strong evidence for fast ($v_{\rm out} \sim 1000~{\rm km\,s}^{-1}$) massive ($\dot{M} =$ several $\times 1000~\msun\,{\rm yr}^{-1}$) gas outflows. Such outflows are expected on theoretical grounds once the central supermassive black hole reaches the mass set by the $M - σ$ relation, and may be what makes galaxies become red and dead. Despite their high velocities, which imply temperatures far above those necessary for molecule dissociation, the outflows contain large amounts of molecular gas. To understand this surprising result, we investigate the gas cooling and show that the outflows cannot stably persist in high--temperature states. Instead the outflowing gas forms a two--phase medium, with cold dense molecular clumps mixed with hot tenuous gas, as observed. We also show that efficient cooling leads to star formation, providing an observable outflow signature. The central parts of the outflows can be intrinsically luminous gamma--ray sources, provided that the central black hole is still strongly accreting. We note also that these outflows can persist for $\sim 10^8$~yr after the central AGN has turned off, so that many observed outflows (particularly with high speeds) otherwise assumed to be driven by starbursts might also be of this type.

Vicarious Sense of Agency in Human-Robot Interaction
Creators: name: ROSELLI, CECILIA
Publisher: name: Universit� degli studi di Genova
Year: 2022

description: Sense of Agency (SoA) is the feeling of having control over one?s actions and outcomes. In humans? daily life, SoA shapes whether, and how, people feel responsible for their actions, which has profound implications for the organization of human societies. Thus, SoA has received considerable attention in psychology and cognitive neuroscience, which tried to identify the cognitive mechanism underlying the emergence of the individual experience of agency. However, humans are inherently social animals, who are deeply immersed in social contexts with others. Thus, investigations of SoA cannot be limited to understanding the individual experience of agency, as SoA also affects the way people experience others? actions: this is how SoA becomes ?vicarious?. Humans can experience vicarious SoA over another human?s actions and outcomes; however, the mechanisms underlying the emergence of vicarious SoA are still under debate. In this context, focusing on artificial agents may help shed light on the vicarious SoA phenomenon. Specifically, robots are an emerging category of artificial agents, designed to assist humans in a variety of tasks- from elderly care to rescue missions. The present Ph.D. thesis aimed at investigating whether, and under which conditions, robots elicit vicarious SoA in humans in the context of Human-Robot Interaction (HRI). Moreover, we aimed at assessing whether vicarious SoA may serve as an implicit measure of intentionality attribution towards robots. The link between vicarious SoA and intentionality attribution was based on the idea that, in some contexts, humans can perceive robots as intentional agents, and it may ?boost? the ?vicarious? control that they experience over robot?s actions and outcomes- as well as it happens with other humans. In three studies, we employed the Intentional Binding (IB) paradigm as a reliable measure of implicit SoA. Participants performed an IB task with different types of robots varying in their degree of anthropomorphic features and human-like shape (i.e., the Cozmo robot and the iCub robot). Specifically, our goal was to assess whether the emergence of vicarious SoA in humans was modulated by (1) the possibility to represent robot?s actions using one?s own motor schemes, (2) the attribution of intentionality towards robots, and (3) the human-like shape of the robot. Our results suggested that the interplay of these three factors modulates the emergence of vicarious SoA in HRI. In conclusion, the findings collected in the present thesis contribute to the field of research on the vicarious SoA phenomenon in HRI, providing useful hints to design robots well-tailored to humans? attitudes and needs.

description: We consider how selfish agents are likely to share revenues derived from maintaining connectivity between important network servers. We model a network where a failure of one node may disrupt communication between other nodes as a cooperative game called the vertex Connectivity Game (CG). In this game, each agent owns a vertex, and controls all the edges going to and from that vertex. A coalition of agents wins if it fully connects a certain subset of vertices in the graph, called the primary vertices. Power indices measure an agents ability to affect the outcome of the game. We show that in our domain, such indices can be used to both determine the fair share of the revenues an agent is entitled to, and identify significant possible points of failure affecting the reliability of communication in the network. We show that in general graphs, calculating the Shapley and Banzhaf power indices is #P-complete, but suggest a polynomial algorithm for calculating them in trees. We also investigate finding stable payoff divisions of the revenues in CGs, captured by the game theoretic solution of the core, and its relaxations, the epsilon-core and least core. We show a polynomial algorithm for computing the core of a CG, but show that testing whether an imputation is in the epsilon-core is coNP-complete. Finally, we show that for trees, it is possible to test for epsilon-core imputations in polynomial time.

description: The capabilities of some approaches to the relativistic description of hadronic states with any rest spin are analysed. The key feature in the Wigner's construction of irreducible representations of the Poincare group which makes this construction fruitless in the particle physics is picked out. A realization of unitary irreducible representations of the Poincare group of the standard type, which yet have never been considered, is discussed. The viability of the description of hadrons by the Poincare group representations of the standard type in the space of the infinite-component ISFIR-class fields is pointed out.

Identifying the Class of Maxi-Consistent Operators in Argumentation

Subjects: subject: Artificial Intelligence (cs.AI)

description: Dung's abstract argumentation theory can be seen as a general framework for non-monotonic reasoning. An important question is then: what is the class of logics that can be subsumed as instantiations of this theory? The goal of this paper is to identify and study the large class of logic-based instantiations of Dung's theory which correspond to the maxi-consistent operator, i.e. to the function which returns maximal consistent subsets of an inconsistent knowledge base. In other words, we study the class of instantiations where very extension of the argumentation system corresponds to exactly one maximal consistent subset of the knowledge base. We show that an attack relation belonging to this class must be conflict-dependent, must not be valid, must not be conflict-complete, must not be symmetric etc. Then, we show that some attack relations serve as lower or upper bounds of the class (e.g. if an attack relation contains canonical undercut then it is not a member of this class). By using our results, we show for all existing attack relations whether or not they belong to this class. We also define new attack relations which are members of this class. Finally, we interpret our results and discuss more general questions, like: what is the added value of argumentation in such a setting? We believe that this work is a first step towards achieving our long-term goal, which is to better understand the role of argumentation and, particularly, the expressivity of logic-based instantiations of Dung-style argumentation frameworks.

description: Seit März 2020 befindet sich die gesamte Schweizer Bevölkerung aufgrund der COVID-19 Pandemie in einem Ausnahmezustand. Die Schweizer Regierung hat zur Eindämmung der Pandemie eine Reihe von Schutzmassnahmen getroffen und eingeführt. Einige Schutzmassnahmen haben tief in die Grundrechte der Schweizer Bevölkerung eingegriffen. Die Erkenntnisse über die Auswirkungen dieser Schutzmassnahmen können durch die Wissenschaft erst mit der Zeit aufgezeigt werden. Dabei zeichnet sich bereits ab, dass nicht alle Bevölkerungsgruppen gleichermassen von diesen Auswirkungen betroffen sind. Als eine besonders von Risiken betroffene Altersgruppe gilt die der “jungen Erwachsenen”. Aufgrund ihrer entwicklungspsychologischen besonderen Lage des Übergangs von der Jugend ins Erwachsenenalter, befinden sie sich in einer für die Identitätsbildung entscheidenden Lebensphase. In der vorliegenden Bachelorarbeit gehen die Autorinnen deshalb den Fragen nach, inwiefern die COVID-19 Pandemie eine besonders prägende Wirkung auf die psychosoziale Gesundheit der “jungen Erwachsenen” gezeigt hat. Dafür haben sich die Autorinnen entschieden auf dem Arbeitsfeld der Klinischen Sozialarbeit in den psychiatrischen Institutionen zu forschen. Die Sozialarbeitenden wurden als Expert*innen befragt und berichteten über ihre Erfahrungen über die Arbeit mit jungen Erwachsenen, sowie aus ihrem Berufsalltag während der COVID-19 Pandemie. Das Resultat dieser Arbeit soll einerseits den Fachleuten der Klinischen Sozialarbeit im Fall einer erneuten pandemischen Lage zu mehr Verständnis im Umgang mit jungen Erwachsenen dienen. Andererseits können die gewonnenen Resultate zur Reflexion ihres professionellen Handelns, während der COVID-19 Pandemie genutzt werden.

description: We present the results of a recent re-reduction of the data from the Very Large Array (VLA) Low-frequency Sky Survey (VLSS). We used the VLSS catalog as a sky model to correct the ionospheric distortions in the data and create a new set of sky maps and corresponding catalog at 73.8 MHz. The VLSS Redux (VLSSr) has a resolution of 75 arcsec, and an average map RMS noise level of $σ\sim0.1$ Jy beam$^{-1}$. The clean bias is $0.66\timesσ$, and the theoretical largest angular size is 36 arcmin. Six previously un-imaged fields are included in the VLSSr, which has an unbroken sky coverage over 9.3 sr above an irregular southern boundary. The final catalog includes 92,964 sources. The VLSSr improves upon the original VLSS in a number of areas including imaging of large sources, image sensitivity, and clean bias; however the most critical improvement is the replacement of an inaccurate primary beam correction which caused source flux errors which vary as a function of radius to nearest pointing center in the VLSS.

description: The academic catalog is a vital record for colleges and universities. Until the late 1980s, Oregon State University catalogs were published, distributed and archived solely in print format. With the advent of web and digital technologies, the Oregon State University Registrar’s Office also began placing an electronic version of the most recent catalogs online, while the Oregon State University Libraries provided access to earlier versions of the catalog through a subscription to College Source®, an online vendor for academic catalogs.

In 2006, the Registrar’s Office was looking for a home for its archive of digital files, while the escalating cost of serials forced Oregon State University Libraries to cut its subscription to College Source®. The two units collaborated to preserve and provide electronic access to the entire run (1866 to present) of Oregon State University academic catalogs in ScholarsArchive, the Libraries’ institutional repository. This article details this collaboration as well as the procedures and workflows for depositing digitized as well as born-digital files into ScholarsArchive (https://ir.library.oregonstate.edu/jspui/) We compare the number of patron requests pre- and post- catalog placement in ScholarsArchive and describe how this project led to the OSU Registrar’s Office placing additional university documents into ScholarsArchive.

We study the phase diagram in the $(β,κ)$ plane performing a detailed analysis of the scaling behavior of the Lee-Yang zeros and the peak height of the chiral susceptibility. Our results strongly indicate that the whole range of the phase transition line starting from $(β,κ)=(0.0,0.380665(59))$ and ending at $(\infty,0.25)$ belongs to the two-dimensional Ising universality class similarly to the free fermion case.

description: In mid-2008, a statewide committee was formed to engage in a comprehensive, Nevada statewide digital planning process. This group consisted of broad membership from the range of Nevada cultural heritage institutions, and was focused on creating a five year digital plan for the state, with an emphasis on collaboration amongst various cultural heritage institutions, increased digitization, and adoption of a digital preservation strategy. This article describes the initial work of the parent committee and two subsequent working groups, funded by the Library Technology and Services Act and aided by outside consultants. Early steps included a comprehensive planning survey and various meetings to understand the capabilities and desires of both primary stakeholders and the community at large. While several challenges not necessarily unique to Nevada arose over the first couple of years, a clear path forward for additional progress has been charted.

description: Given a current news event, we tackle the problem of generating plausible predictions of future events it might cause. We present a new methodology for modeling and predicting such future news events using machine learning and data mining techniques. Our Pundit algorithm generalizes examples of causality pairs to infer a causality predictor. To obtain precisely labeled causality examples, we mine 150 years of news articles and apply semantic natural language modeling techniques to headlines containing certain predefined causality patterns. For generalization, the model uses a vast number of world knowledge ontologies. Empirical evaluation on real news articles shows that our Pundit algorithm performs as well as non-expert humans.

description: Machine learning plays a vital role in research, extracting profound insights from complex datasets, expediting data analysis and pattern recognition. Its capacity to unveil hidden relationships empowers cross-disciplinary decision-making, predictive modeling, and novel discoveries. However, the intricacies of machine learning models may hinder non-technical users in both implementation and interpretation, necessitating for user-friendly tools. Within the Cloud and Interactive Computing group (CIC) at the Texas Advanced Computing Center (TACC), we are actively developing a Machine Learning Hub (ML Hub) API, that integrates seamlessly into the Tapis Framework. Designed as a set of user-friendly microservices, each service provides an independent REST API over HTTP, codified using OpenAPI v3 definitions, and implemented in Python's Flask. Our research seeks to amplify the experiences of developers, scientists, and researchers in machine learning. By integrating Hugging Face's API into ML Hub, we aim to provide open-source pre-trained machine learning models, allowing developers to harness state-of-the-art AI capabilities. Currently, the Models Overview and Models Download functions in ML Hub provide a single point of access for non-technical users to explore and download available machine learning models. All service requests are authenticated using a JSON Web Token (JWT) from the Tapis Tokens API. Future efforts involve implementing the Inference Client and Training Engine, as well as ensuring seamless integration into the Tapis user interface, developed in React and Typescript. Core attributes of ML Hub: 1. Models Overview: The portal showcases top Hugging Face models, allowing users to filter by author and access detailed specifics. 2. Models Download: Users can obtain specific models, with options to either download a binary file of the model or a zip file containing the model's repository, cached in a version-aware manner. 3. Inference Client: Facilitating server initiation for machine learning model inference on TACC's HPC cluster, enabling rapid prototyping. 4. Training Engine: Enabling users to fine-tune models and showcase them on TACC's HPC cluster, removing technical complexities. This research contributes to the broader discourse on democratizing machine learning's potential, by providing user-friendly access to state-of-the-art models and addressing non-technical users' challenges. We hope that this project will foster innovative collaboration and user engagement, paving the way for an inclusive and impactful future in machine learning research.

description: The oscillation properties of a spin torque oscillator consisting of a perpendicularly magnetized free layer and an in-plane magnetized pinned layer are studied based on an analysis of the energy balance between spin torque and damping. The critical value of an external magnetic field applied normal to the film plane is found, below which the controllable range of the oscillation frequency by the current is suppressed. The value of the critical field depends on the magnetic anisotropy, the saturation magnetization, and the spin torque parameter.

Neumann Problem for Helmholtz Equation in Two-Dimensional Open Domains with Applications

Subjects: Other education not elsewhere classified

description: The research described in the thesis is devoted to a rigorous solution of the Neumann boundary value problem for the Helmholtz equation in two-dimensional open arbitrary domains, and its application to the diverse problems of practical acoustics and electro-engineering. The Method of Analytical Regularisation is used to transform the initial surface integral equation in the form of a double layer potential to well-conditioned coupled infinite systems of linear algebraic equations, thus addressing the hyper-singular kernel arising from the normal derivative of the double layer potential. The compactness of the matrix operators provides the fast convergence of the truncated versions of the infinite systems, numerical solution of which may be obtained with any predetermined accuracy. Furthermore, complex eigenvalues of natural complex oscillations for various structures have been analysed extensively, using the spectral parameter (frequency) for which the matrix operator has zero valued determinant. A root finding algorithm is developed to improve the accuracy of the calculations as well as the computation time and performance. The developed method uses the spectral map of truncated system condition number for initial approximations. There are no restrictions imposed on boundaries of domains (except requirements on smoothness of the bounding contours), frequency range and size of entries (slits). To take advantage of all these merits of the solution, an object-oriented software for its numerical implementation has been developed: bounding contours of slotted arbitrary cylinders are generated by interpolation functions and Sobolev’s approximation, providing a smooth parametrisation. The numerical results cover spectral studies and resonance excitation of the slotted cylinders. Spectral studies of classical (closed) waveguides, ridged waveguides, and magnetron-type resonator cavities reveal an excellent agreement with the results available in literature. Complex eigenvalues associated with slotted arbitrary cylinders are obtained for the first time. Classical cylinders (circular, elliptic and rectangular) as well as their corrugated and modified shapes (single and paired acoustic resonators with attached necks, polygonal and sinusoidally corrugated cylinders) are investigated. Finally, wave scattering from slotted circular, elliptic, rectangular cavities, duct and bent duct cavities, parabolic reflector antennas (with and without flanges), corner reflectors, finite sinusoidally profiled gratings, and complex shapes such as an airplane and a submarine are studied. The MAR approach allows calculation of radar cross sections, scattering patterns and field distributions for a frequency range from a few to a half-thousand wavelengths, covering the low-frequency region (Rayleigh scattering), the resonance regime (diffraction), and the high-frequency regions.
J-VAR: Observing the Variable Sky in 7 colours

description: Over the course of the last century, several projects aimed at time-domain astrophysics have been carried out. Yet, most of these efforts focus on one (or, at most, a few) broad-band photometric filters, thus somewhat limiting the amount of astrophysical information which can be extracted from the data.
J-VAR is a novel concept for a time-domain survey which is being carried out with the 80cm Javalambre Auxiliary Survey Telescope at the Observatorio Astrofísico de Javalambre (OAJ) on non-photometric nights. J-VAR observes in 7 filters, three broad bands (g, r, and i from the SDSS system) and 4 narrow band filters. This allows for the study of the variation of the optical spectral energy distribution.
Here we present the preliminary results from the first data release of the project, covering 200 square degrees, focusing on the three pillars of our project: Solar System objects, optical transients, and variable stars. We also discuss the complementarity with other current and future photometric surveys.

description: Flower pollination algorithm is a new nature-inspired algorithm, based on the characteristics of flowering plants. In this paper, we extend this flower algorithm to solve multi-objective optimization problems in engineering. By using the weighted sum method with random weights, we show that the proposed multi-objective flower algorithm can accurately find the Pareto fronts for a set of test functions. We then solve a bi-objective disc brake design problem, which indeed converges quickly.

Subjects: Sociology of mental health and disorders

description: Mental health settings: These are dynamic spaces where patients, places, healthcare professionals, supervision and discipline interact spatially. The experience of the subject in mental health settings where daily routines take place in a specific spatial area provides information on mental hospitals. It is very important to use past conceptual frameworks as a "tool kit" to understand mental health spaces. This study includes a summary of past and current debates on space conceptualizations and mental health sociology. As a mental health space in the context of the sociology of space and mental health, Bakırköy Prof. Dr. Mazhar Osman Mental Health and Neurological Diseases Training and Research Hospital was chosen as the sample area in this study. Interviews were made with the staff at the Bakırköy Mental Health and Neurological Diseases Hospital on the internet regarding which daily rituals the mental health centers are based on and what kind of places the mental health centers are, observations were made even for a limited time in the hospital, and a documentary on Bakırköy, interviews and articles were examined. As a result of the examination, the mental health space affects the selves of both patients and healthcare personnel who interact with that place in the institution, and the space is more than just a "madhouse"; It is concluded that it is experienced as a "home", a "training place", "a giant garden" and a "peace area". However, this result is thought to be an imperfect reflection of the reality of the space, as patients in the space are not communicated with.
