description: We apply a recently developed adaptive algorithm that systematically improves the efficiency of parallel tempering or replica exchange methods in the numerical simulation of small proteins. Feedback iterations allow us to identify an optimal set of temperatures/replicas which are found to concentrate at the bottlenecks of the simulations. A measure of convergence for the equilibration of the parallel tempering algorithm is discussed. We test our algorithm by simulating the 36-residue villin headpiece sub-domain HP-36 wherewe find a lowest-energy configuration with a root-mean-square-deviation of less than 4 Angstroem to the experimentally determined structure.

description: Luminous Blue Variables are massive evolved stars, here we introduce this outstanding class of objects. Described are the specific characteristics, the evolutionary state and what they are connected to other phases and types of massive stars. Our current knowledge of LBVs is limited by the fact that in comparison to other stellar classes and phases only a few ``true'' LBVs are known. This results from the lack of a unique, fast and always reliable identification scheme for LBVs. It literally takes time to get a true classification of a LBV. In addition the short duration of the LBV phase makes it even harder to catch and identify a star as LBV. We summarize here what is known so far, give an overview of the LBV population and the list of LBV host galaxies. LBV are clearly an important and still not fully understood phase in the live of (very) massive stars, especially due to the large and time variable mass loss during the LBV phase. We like to emphasize again the problem how to clearly identify LBV and that there are more than just one type of LBVs: The giant eruption LBVs or $η$ Car analogs and the S Dor cycle LBVs.

description: The mission of the ELIXIR Data Platform is to deliver a sustainably funded portfolio of Core Data Resources that exemplify excellence within a coordinated and vibrant ecosystem of Node Data Resources, to meet the needs of the European life science research community. The overall objective of Work Package 3 is to build a framework to inform and drive the sustainable development of Europe’s Core life-science Data Resources. ELIXIR aims to ensure that these resources are available long-term and that the life cycles of these resources are managed such that they support the scientific needs of the life sciences and biological research. In addition, Work Package 3 promotes excellence in resource development and operation through providing a unified framework for the identification and monitoring of key bioinformatics resources across Europe. Running two iterations of the process to select ELIXIR Core Data Resources has informed us how best to collect all the required indicators. While some indicators never or rarely need updating, others can only be collected manually. As discussed in detail in this report, some indicators are automatically collected on a local level, while for others, collection can be centralised. The adopted approach therefore maintains a pragmatic balance between automated collection (local and centralised) and manually collated updates. The Core Data Resource selection and update processes that are currently in place only require modest human resources at the ELIXIR Hub and little specialized technical knowledge, making these processes easily sustainable over time. Having defined the Core Data Resources, and implemented annual collection of Indicator data, Work Package 3 has produced an article “The ELIXIR Core Data Resources: fundamental infrastructure for the life sciences” and posted it as a preprint on bioRxiv as well as submitting it to the Bioinformatics journal. This is the first such analysis to be conducted on such a collection, and will be a powerful tool in the ongoing work towards long term sustainability of life science data resources.

description: We investigate the stochastic gravitational wave background (SGWB) from cosmic domain walls (DWs) caused by quantum fluctuations of a light scalar field $ϕ$ during inflation. Perturbations of $ϕ$ remain almost constant after leaving the Hubble horizon. The probabilities of the two domains depend on the averaged value of $ϕ$ at each large scale region, leading to large scale perturbations of DW energy density and large anisotropies in the SGWB. We find that the angular power spectrum is scale-invariant and at least of the order of $10^{-2}$, which is expected to be detected by future gravitational-wave (GW) detectors. Since we have not detected primordial GWs yet, anisotropies of the SGWB could help us to verify the rationality of inflation and determine the energy scale of inflation.

description: In this study, entitled "Α sociolinguistic approach of dialectal variety of the island of Lesvos. Language attitudes in the areas Agiasos and Plomari "a sociolinguistic view of the language systems of the island is considered, focusing on language attitudes of residents of areas Agiasos and Plomari. Firstly, we define the language systems of Agiasos and Plomari as dialectal varieties / regional accents of the mentioned regions, and afterwards we explain the reasons of our choice and we present some basic linguistic features of the two language systems, as reported by sources. The sociolinguistic research that followed is one of the few researches of this field that have been conducted in these areas. The aim of our research is to record and study the language attitudes of speakers of these dialectal varieties, both towards their own language system (self-evaluative attitudes) and towards the other linguistic community ( hetero-evaluative attitudes).The ultimate goal of our research is to record the internalized ideology of the two linguistic communities that is reflected in language behavior.
A multi-objective reliability-redundancy allocation problem with active redundancy and interval type-2 fuzzy parameters
Creators: name: Kundu, Pradip
Publisher: name: arXiv
Year: 2020
Subjects: subject: Optimization and Control (math.OC)
subject: FOS: Mathematics

description: This paper considers a multi-objective reliability-redundancy allocation problem (MORRAP) of a series-parallel system, where system reliability and system cost are to be optimized simultaneously subject to limits on weight, volume, and redundancy level. Precise computation of component reliability is very difficult as the estimation of a single number for the probabilities and performance levels are not always possible, because it is affected by many factors such as inaccuracy and insufficiency of data, manufacturing process, environment in which the system is running, evaluation done by multiple experts, etc. To cope with impreciseness, we model component reliabilities as interval type-2 fuzzy numbers (IT2 FNs), which is more suitable to represent uncertainties than usual or type-1 fuzzy numbers. To solve the problem with interval type-2 fuzzy parameters, we first apply various type-reduction and defuzzification techniques, and obtain corresponding defuzzified values. As maximization of system reliability and minimization of system cost are conflicting to each other, so to obtain compromise solution of the MORRAP with defuzzified parameters, we apply five different multi-objective optimization methods, and then corresponding solutions are analyzed. The problem is illustrated numerically for a real-world MORRAP on pharmaceutical plant, and solutions are obtained by standard optimization solver LINGO, which is based on gradient-based optimization - Generalized Reduced Gradient (GRG) technique.

description: Zirconia (ZrO2) and hafnia (HfO2) are leading candidates for replacing SiO2 as the gate insulator in CMOS technology. Amorphous versions of these materials (a-ZrO2 and a-HfO2)) can be grown as metastable phases on top of a silicon buffer; while they tend to recrystallize during subsequent annealing steps, they would otherwise be of considerable interest because of the promise they hold for improved uniformity and electrical passivity. In this work, we report our theoretical studies of a-ZrO2 and a-HfO2 by first-principles density-functional methods. We construct realistic amorphous models using the ``activation-relaxation'' technique (ART) of Barkema and Mousseau. The structural, vibrational, and dielectric properties of the resulting models are analyzed in detail. The overall average dielectric constant is computed and found to be comparable to that of the monoclinic phase.

description: The neighborhood of Kypseli in Athens is the research area of the present thesis, with the aim of a new urban planning organization and a framework of spatial policy proposals, which will attempt to replace its structural and social problems in terms of inclusive functioning and sustainability.
The analysis and evaluation of the existing situation, which constitute the first part of the thesis, identify the weaknesses and possibilities inherent in land uses, the housing stock and public spaces, record the traffic networks of vehicles and pedestrians, calculate the building conditions and their deviations from the statutory ones, while also taking into account special social elements that need to be studied, such as the cultural and ethnic origins of Kypseli. In the second part of the thesis, the frameworks of changes on an urban planning scale are proposed, with the aim of regulating the issues that emerge from the conclusions of the first part, in order to achieve the change of the life conditions in the area based on the guiding principles that are set in the central purpose of our thesis.

description: In our previous papers we proposed a continuum model for the dynamics of the systems of self-propelling particles with conservative kinematic constraints on the velocities. We have determined a class of stationary solutions of this hydrodynamic model and have shown that two types of stationary flow, linear and radially symmetric (vortical) flow, are possible. In this paper we consider the stability properties of these stationary flows. We show, using a linear stability analysis, that the linear solutions are neutrally stable with respect to the imposed velocity and density perturbations. A similar analysis of the stability of the vortical solution is found to be not conclusive.

description: The PandaX project consists of a series of xenon-based experiments that are used to search for dark matter (DM) particles and to study the fundamental properties of neutrinos. The next DM experiment PandaX-4T will be using 4 ton liquid xenon in the sensitive volume, which is nearly a factor of seven larger than that of the previous experiment PandaX-II. Due to the increasing target mass, the sensitivity of searching for both DM and neutrinoless double-beta decay ($0νββ$) signals in the same detector will be significantly improved. However, the typical energy of interest for $0νββ$ signals is at the MeV scale, which is much higher than that of most popular DM signals. In the baseline readout scheme of the photomultiplier tubes (PMTs), the dynamic range is very limited. Signals from the majority of PMTs in the top array of the detector are heavily saturated at MeV energies. This deteriorates the $0νββ$ search sensitivity. In this paper we report a new design of the readout base board of the PMTs for future PandaX DM experiments and present its improved performance on the dynamic range.

description: Electronic transport in diatomic molecules (two-level systems) connected to metallic contacts is analyzed in the presence of competing electron-electron and electron-phonon interactions. We show that phonon emission and absorption processes are strongly modified when a Coulomb energy $U$ is included, as the phonons open channels that can result in destructive or constructive interference effects. Resonance conditions for these processes produce dramatic effects both in the density of states at the molecular sites, as well as in the conductance through the system. We find in particular an enhanced {\it Rabi-assisted tunneling} due to phonons, as the resonance conditions are met, which is made more evident for increasing temperatures. These effects are controllable by voltage gating of the molecular sites, and should be accessible in current experiments.

description: We use a quantum Monte Carlo method to calculate the Neel temperature T_N of weakly coupled S=1/2 Heisenberg antiferromagnetic layers consisting of coupled ladders. This system can be tuned to different two-dimensional scaling regimes for T > T_N. In a single-layer mean-field theory, χ_s^{2D}(T_N)=(z_2J')^{-1}, where χ_s^{2D} is the exact staggered susceptibility of an isolated layer, J' the inter-layer coupling, and z_2=2 the layer coordination number. With a renormalized z_2, we find that this relationship applies not only in the renormalized-classical regime, as shown previously, but also in the quantum-critical regime and part of the quantum-disordered regime. The renormalization is nearly constant; k_2 ~ 0.65-0.70. We also study other universal scaling functions.

description: This research studies the relationship between persecutory delusions and the person’s biography. In particular, a variety of issues is explored, like social circumstances and genetic factors that contributed to the generation of persecutory delusions, the relationship between the content of the persecutory delusions and the biography of the person, the functioning of the paranoid delusions, the attributional biases and finally, how the participants themselves explain the experience of psychosis in general and especially the experience of persecutory delusions. This research is based on notes from interviews from 5 men with persecutory delusions, who have been diagnosed as having paranoid schizophrenia, which have been supplemented with information from employees at the psychosocial rehabilitation services, which the participants use and their psychiatric and social records. The narrations that were constructed, were qualitatively analyzed. The conclusion was that elements of the biography were running through all the factors that were studied. In addition, it was observed that the life history of every person is unique and special and this was confirmed by the difficulty in the categorization of the experiences that were reported. Finally the conclusions and their possible usefulness in future research are commented.

description: Vehicle-to-vehicle (V2V) communication appeals to increasing research interest as a result of its applications to provide safety information as well as infotainment services. The increasing demand of transmit rates and various requirements of quality of services (QoS) in vehicular communication scenarios call for the integration of V2V communication systems and potential techniques in the future wireless communications, such as full duplex (FD) and non-orthogonal multiple access (NOMA) which enhance spectral efficiency and provide massive connectivity. However, the large amount of data transmission and user connectivity give rise to the concern of security issues and personal privacy. In order to analyze the security performance of V2V communications, we introduce a cooperative NOMA V2V system model with an FD relay. This paper focuses on the security performance of the FD-NOMA based V2V system on the physical layer perspective. We first derive several analytical results of the ergodic secrecy capacity. Then, we propose a secrecy sum rate optimization scheme utilizing the instantaneous channel state information (CSI), which is formulated as a non-convex optimization problem. Based on the differential structure of the non-convex constraints, the original problem is approximated and solved by a series of convex optimization problems. Simulation results validate the analytical results and the effectiveness of the secrecy sum rate optimization algorithm.

The efficacy of visually-based and aurally-based instrumental music instruction techniques in the development of music reading skills of beginning instrumental music students
Creators: name: Toren, Stephen C.
Publisher: name: University of British Columbia
Year: 2009

description: This study was undertaken in an effort to determine if there are differences between visual and aural approaches to tonal and rhythm reading instruction. Grade five beginning instrumental music students received instruction using one of two visual treatments or using an aural treatment. No significant difference was found between treatments for tonal or rhythm reading skills. A significant difference was found between students who possess either high or low aptitude levels on tonal reading skills. It was concluded that beginning instrumentalists who possess high tonal audiation ability develop better music reading skills than students who possess low tonal audiation ability. Also, it was concluded that music teachers who are interested in teaching both aural and music reading skills may do so without detriment to beginning instrumentalists.

description: We perform a systematic study of the multi-wavelength signal induced by weakly interacting massive particle (WIMP) annihilations at the Galactic Center (GC). Referring to a generic WIMP dark matter (DM) scenario and depending on astrophysical inputs, we discuss spectral and angular features and sketch correlations among signals in the different energy bands. None of the components which have been associated to the GC source Sgr A*, nor the diffuse emission components from the GC region, have spectral or angular features typical of a DM source. Still, data-sets at all energy bands, namely, the radio, near infrared, X-ray and gamma-ray bands, contribute to place significant constraints on the WIMP parameter space. In general, the gamma-ray energy range is not the one with the largest signal to background ratio. In the case of large magnetic fields close to the GC, X-ray data give the tightest bounds. The emission in the radio-band, which is less model dependent, is very constraining as well. The recent detection by HESS of a GC gamma-ray source, and of a diffuse gamma-ray component, limits the possibility of a DM discovery with next generation of gamma-ray telescopes, like GLAST and CTA. We find that the most of the region in the parameter space accessible to these instruments is actually already excluded at other wave-lenghts. On the other hand, there may be still an open window to improve constraints with wide-field radio observations.

♀. Tout à fait semblable au mâle, avec l'abdomen plutôt marron, les appendices brun clair, extrêmement minces et courts.
Habitat Afrique continentale, probablement orientale.
 Cette espèce ressemble beaucoup à L. simulatrix et la représente sur le continent; c`est plutot méme une simple race de simulatrix, dont elle diffère par la taille un peu plus petite, quelque diversité de coloration et quelques differences dans la forme des appendices du mâle, seul décrit par Mac Lachlan.

description: Generally, in transportation problem, full vehicles (e.g., light commercial vehicles, medium duty and heavy duty trucks, etc.) are to be booked, and transportation cost of a vehicle has to be paid irrespective of the fulfilment of the capacity of the vehicle. Besides the transportation cost, total time that includes travel time of a vehicle, loading and unloading times of products is also an important issue. Also, instead of a single item, different types of items may need to be transported from some sources to destinations through different types of conveyances. The optimal transportation policy may be affected by many other issues like volume and weight of per unit of product, unavailability of sufficient number of certain types of vehicles, etc. In this paper, we formulate a multi-objective multi-item solid transportation problem by addressing all these issues. The problem is formulated with the transportation cost and time parameters as fuzzy variables. Using credibility theory of fuzzy variables, a chance-constraint programming model is formulated, and is then transformed into the corresponding deterministic form. Finally numerical example is provided to illustrate the problem.

description: Estimating 3D hand pose directly from RGB imagesis challenging but has gained steady progress recently bytraining deep models with annotated 3D poses. Howeverannotating 3D poses is difficult and as such only a few 3Dhand pose datasets are available, all with limited samplesizes. In this study, we propose a new framework of training3D pose estimation models from RGB images without usingexplicit 3D annotations, i.e., trained with only 2D informa-tion. Our framework is motivated by two observations: 1)Videos provide richer information for estimating 3D posesas opposed to static images; 2) Estimated 3D poses oughtto be consistent whether the videos are viewed in the for-ward order or reverse order. We leverage these two obser-vations to develop a self-supervised learning model calledtemporal-aware self-supervised network (TASSN). By en-forcing temporal consistency constraints, TASSN learns 3Dhand poses and meshes from videos with only 2D keypointposition annotations. Experiments show that our modelachieves surprisingly good results, with 3D estimation ac-curacy on par with the state-of-the-art models trained with3D annotations, highlighting the benefit of the temporalconsistency in constraining 3D prediction models.

description: Στην εργασία «Άγαμη μητέρα, ποιμαντική θεώρηση» ασχολούμαστε με το κοινωνικό φαινόμενο «άγαμη μητέρα», τους λόγους που οδηγούν μια γυναίκα στην απόφαση αυτή, τα προβλήματα που αντιμετωπίζει και τους τρόπους με τους οποίους μπορούν να λυθούν. Αναφερόμαστε στην αρχή στα διάφορα σχήματα οικογενειακής οργάνωσης που αρχίζουν να επικρατούν όπως είναι οι επαναδημιουργημένες οικογένειες, η ελεύθερη συμβίωση και οι μονογονεϊκές οικογένειες. Έπειτα ακολουθεί μια εννοιολογική προσέγγιση του θέματος όπου γίνεται αναφορά στο τι είναι ο γάμος και η οικογένεια και το ρόλο του κάθε μέλους μιας οικογένειας. Στη συνέχεια μιλάμε για το τι είναι άγαμη μητέρα και σε ποιες κατηγορίες που μπορούμε να διαχωρίσουμε τις μόνες-μητέρες. Έπειτα αναφερόμαστε στους λόγους που πιστεύουμε ότι «ευθύνονται» για το φαινόμενο «άγαμη μητέρα» και αυτοί είναι οι προγαμιαίες ερωτικές σχέσεις, η απόρριψη του Mυστηρίου του Γάμου και οι «χαμένες αξίες». Έπειτα κάνουμε μια κοινωνική προσέγγιση του θέματος και αναφερόμαστε στα προβλήματα που έχουν να αντιμετωπίσουν οι άγαμες μητέρες αλλά και σε αυτά που προκαλούνται από την ύπαρξη τους. Αναφερόμαστε επίσης και στα μέτρα που έχει πάρει η Πολιτεία αλλά και σε αυτά που θα μπορούσε να πάρει για την αντιμετώπιση του φαινομένου. Τέλος έχουμε την ποιμαντική προσέγγιση όπου βλέπουμε το θέμα από την πλευρά της Εκκλησίας και κάνουμε μια μικρή αναφορά στο έργο κάποιων ιδρυμάτων, των οποίων ο σκοπός τους είναι να βοηθήσουν την άγαμη μητέρα και το παιδί της.
description: In the project “Single mother, pastoral view” we deal with the social phenomenon “single mother”, the reason who lead a woman to become a single mother, the problems she has to deal with and the solutions of them. In the beginning we refer to some new figures of family organizations that begin to prevail such as the again-created families, the free living-together and the single-parent families. Then we have a semantic approach of the subject. We deal with the meaning of what are a marriage and a family and the role of its member. Then we deal with the meaning of what is a single mother and the categories we can separate them. After we refer to the reasons that we think they are responsible to the social phenomenon “single mother” such as the premarital sex, the rejection of the Sacrament of Marriage and the “lost values”. Then we have a social approach of the subject and we refer to the problems that a single mother could have but also and to them she is responsible for. We refer also to the measures the Government have take and also could take. At the end we have the pastoral approach where we view the subject from the Church’s position and we refer to the work of some foundations which target is to help the single mother and her child.

 On pourrait se demander si les trois formes simulatrix, simulans et; pruinescens n'appartiendraient pas à la même espèce..J'ai cependant cru devoir les séparer en l'état actuel, d 'autant mieux que la coloration de pruinescens, absolument particulière, semble ne pouvoir être la coloration a Pétat très adulte des autres espèces.

description: Extended X-ray absorption fine structure (EXAFS) experiments at the Zr K-edge were carried out on perovskite relaxor ferroelectrics BaTi(1-x)Zr(x)O3 (BTZ) (x = 0.25, 0.30, 0.35), and on BaZrO3 for comparison. Structural information up to 4.5 A around the Zr atoms is obtained, revealing that the local structure differs notably from the average Pm-3m cubic structure deduced from X-ray diffraction. In particular, our results show that the distance between Zr atoms and their first oxygen neighbors is independent of the Zr substitution rate x and equal to that measured in BaZrO3, while the X-ray cubic cell parameter increases linearly with x. Furthermore, we show that the Zr atoms tend to segregate in Zr-rich regions. We propose that the relaxor behavior in BTZ is linked to random elastic fields generated by this particular chemical arrangement, rather than to random electric fields as is the case in most relaxors.

description: Ο βασικός στόχος της παρούσας έρευνας είναι η ανακάλυψη της «αλήθειας» των ανθρώπων που ζούνε σε ορεινές αγροτικές περιοχές. Η εργασία προσανατολίζεται στην αναζήτηση στοιχείων για την κατασκευή και δόμηση των απόψεων, των στάσεων και των συμπεριφορών των κατοίκων της ορεινής περιοχής του Γράμμου απέναντι στο περιβάλλον. Η έρευνα αφορά σε δύο χωριά του Δήμου Ακριτών του Νομού Καστοριάς. Για την προσέγγιση του θέματος ακολουθήθηκαν η αφηγηματική βιογραφική προσέγγιση, η συμμετοχική παρατήρηση και η ομάδα εστίασης. Το υλικό που συλλέχθηκε παρουσιάζει με περιγραφικό τρόπο τους θεμέλιους λίθους και τα στοιχεία που καθορίζουν και χαρακτηρίζουν αυτή τη σχέση. Η ενεργός συμμετοχή και η έντονη εμπλοκή με τον πληθυσμό της περιοχής οδήγησε στην προσέγγιση του θέματος βάση της «αλήθειας» των εμπλεκόμενων. Σε αυτή τη διαδικασία ήμασταν όλοι και όλες οι εμπλεκόμενοι/ες υπό παρατήρηση και έρευνα, τόσο οι κάτοικοι της περιοχής όσο και η ερευνήτρια. Για αυτό το λόγο η εργασία έχει δομή απαλλαγμένη από πρότυπα και θεωρητικούς περιορισμούς, ενώ προσπαθεί να προβάλλει με γνησιότητα τις απόψεις και θεωρίες των κατοίκων της.
description: The main objective of the present research is the discovery of the "truth" of the people living in mountainous rural areas. The thesis focuses on searching for data concerning the construction and layout of views, attitudes and behaviors of residents of the mountainous region of Grammos towards the environment. The survey carried out in two villages of the municipality Akriton located in the prefecture of Kastoria. The biographical narrative approach, the participatory observation and the focus group were followed for the approach of the subject. The material collected, presents in a descriptive way the building blocks and elements that define and characterize that relationship. The active participation and deep involvement with the local population led to the approach of the subject based on the "truth" of the participants. In this process we were all involved through observation and investigation, both the residents of the area and the researcher. For this reason the present thesis has a structure free of standards and theoretical limitations, while trying to show with authenticity the views and theories of the residents of the local community.

description: We consider a hypothesis testing problem where a part of data cannot be observed. Our helper observes the missed data and can send us a limited amount of information about them. What kind of this limited information will allow us to make the best statistical inference? In particular, what is the minimum information sufficient to obtain the same results as if we directly observed all the data? We derive estimates for this minimum information and some other similar results.
