description: We review fundamental issues arising in the exact solution of the one-dimensional Hubbard model. We perform a careful analysis of the Lieb-Wu equations, paying particular attention to so-called `string solutions'. Two kinds of string solutions occur: $Λ$ strings, related to spin degrees of freedom and $k-Λ$ strings, describing spinless bound states of electrons. Whereas $Λ$ strings were thoroughly studied in the literature, less is known about $k-Λ$ strings. We carry out a thorough analytical and numerical analysis of $k-Λ$ strings. We further review two different approaches to the thermodynamics of the Hubbard model, the Yang-Yang approach and the quantum transfer matrix approach, respectively. The Yang-Yang approach is based on strings, the quantum transfer matrix approach is not. We compare the results of both methods and show that they agree. Finally, we obtain the dispersion curves of all elementary excitations at zero magnetic field for the less than half-filled band by considering the zero temperature limit of the Yang-Yang approach.

description: Chiral active particles, or self-propelled circle swimmers, from sperm cells to asymmetric Janus colloids, form a rich set of patterns, which are different from those seen in linear swimmers. Such patterns have mainly been explored for identical circle swimmers, while real-world circle swimmers, typically possess a frequency distribution. Here we show that even the simplest mixture of (velocity-aligning) circle swimmers with two different frequencies, hosts a complex world of superstructures: The most remarkable example comprises a microflock pattern, formed in one species, while the other species phase separates and forms a macrocluster, coexisting with a gas phase. Here, one species microphase-separates and selects a characteristic length scale, whereas the other one macrophase separates and selects a density. A second notable example, here occurring in an isotropic system, are patterns comprising two different characteristic length scales, which are controllable via frequency and swimming speed of the individual particles.

description: The "Activity Theory" is a modern social learning theory, which attempts to offer a different way of approaching learning by emphasizing on the kind and quality of the activities of the subjects, as a key learning factor. On the basis of the "Activity Theory" the "activity" is understood as a set of individual actions of personal character, which influence and interact on each other formulating a common systemic framework of activity in its own personality, character and orientation, that is the result both of the interconnection of different systemic considerations, and of the (existence) historicity of the roles and transformations leading to situations of individual and collective change. The potential of the principles of “Activity Theory” is to be highlighted in this paper through its application on the design of the lesson planning process of the Religious Education subject, focusing on issues related to the transformation of religious concepts into the learning content, as well as on the main learning processes leading the learning subjects into cognitive and socio-emotional change through such educational interventions and adaptations.

description: A discussion about dependences of the (fractal) basin boundary dimension with the definition of the basins and the size of the exits is presented for systems with one or more exits. In particular, it is shown that the dimension is largely independent of the choice of the basins, and decreases with the size of the exits. Considering the limit of small exits, a strong relation between fractals in exit systems and chaos in closed systems is found. The discussion is illustrated by simple examples of one-dimensional maps.

description: Children with language and learning disorders in mainstream classrooms are following the same curriculum as students without disorders. A key manifestation of language and learning disorders are the difficulties of understanding and producing narrative discourse . It is imperative to support these students applying specialized strategy training intervention programs in the classroom. Narrative strategy intervention programmes are useful for every child. The aim of this work is to analyze the narrative disorders from the perspective of different cognitive approaches and to present cognitive intervention methods that can be exploited in the general classroom.

description: If the Higgs boson is a pseudo Nambu-Goldstone boson (PNGB), the $hZγ$ contact interaction induced by the $\mathcal{O}(p^4)$ invariants of the non-linear sigma model is free from its nonlinearity effects. The process $h\rightarrow Zγ$ can be used to eliminate the universal effects of heavy particles, which can fake the nonlinearity effects of the PNGB Higgs boson in the process $h\rightarrow V^*V$ ($V=W^\pm$,\ $Z$). We demonstrate that the ratio of the signal strength of $h\rightarrow Zγ$ and $h\rightarrow V^*V$ is good to distinguish the signature of the PNGB Higgs boson from Higgs coupling deviations.

description: Este artículo aborda las leyes ambientales del contexto territorial del estado de Rio de Janeiro, en Brasil. Se hace una revisión de la historia de la conformación del campo político y jurídico ambiental de este estado brasileño. Desde una perspectiva histórica, se presentan las diferentes fases del tratamiento institucional de la naturaleza. La intención es señalar que, a pesar de que el “tema ambiental” aún no había sido nombrado como tal, los antecedentes de las leyes y políticas ambientales en el contexto actual son más antiguos que ciertos hitos de la segunda mitad del siglo XX, definidos desde una perspectiva hegemónica. Por un lado, es cierto que parte de las estructuras actuales se conformaron hace pocas décadas. Por otro lado, la política ambiental se remonta a procesos anteriores, como una actividad que tiene que ver con la conformación del Estado mismo y su maquinaria. Más allá de la idea de que el Estado se encarga de la naturaleza bajo el canon jurídico de la posguerra y los derechos fundamentales solo en la segunda mitad del siglo XX, se postula que el tratamiento institucional de la naturaleza tiene raíces profundas que llegan hasta el pasado colonial de Brasil.
description: Environmental laws in Rio de Janeiro/Brazil: a historical look from colonial Brazil to the neoliberalization of nature
 This article examines with environmental laws in the territorial context of the state of Rio de Janeiro, Brazil. A review is made of the history of the conformation of the environmental political and legal field of this Brazilian state. From a historical perspective, the different phases of the institutional treatment of nature are presented. The intention is to point out that, although the "environmental issue" had not yet been named as such, the antecedents of environmental laws and policies in the current context are older than certain milestones of the second half of the 20th century, defined from a hegemonic perspective. On the one hand, it is true that part of the current structures were formed a few decades ago. On the other hand, environmental policy goes back to earlier processes, as an activity that has to do with the conformation of the State itself and its machinery. Beyond the idea that the State is in charge of nature under the post-war legal canon and fundamental rights only in the second half of the twentieth century, it is postulated that the institutional treatment of nature has deep roots that go back to Brazil's colonial past.

description: Second electron affinities of Au_N and Ag_N clusters and the dissociation energies for fission of the Au_N^{2-} and Ag_N^{2-} dianions are calculated using the finite-temperature shell-correction method and allowing for triaxial deformations. Dianionic clusters with N > 2 are found to be energetically stable against fission, leaving electron autodetachment as the dominant decay process. The second electron affinities exhibit pronounced shell effects in excellent agreement with measured abundance spectra for Au_N^{2-} (N < 30), with appearance sizes N=12 for gold dianionic clusters and N=24 for silver dianionic clusters.

description: This paper aims to present innovative teaching strategies in the context of “University Teaching”, which has systematically cultivated in many foreign academic institutions abroad. The development of this branch of teaching and learning methodology (didactics), and the related interest of institutions for effective teaching and learning are integral to the changes observed at the level of international policy for higher education, which redirect to the “knowledge and market economy”. In this context, the academic teaching acquires new content: many foreign universities accept that teaching can not continue to be the “poor relative” of research. Thus, they are financing the establishment of centers or institutes for teaching and staff development, while promoting research in the cognitive domain of concrete objects and seeking to establish friendly teaching and learning environments. The adoption of innovative teaching and learning strategies requires general change in the culture of the university organization and, of course, changes in attitudes and practices of academic staff. Moreover, it is necessary to reform the content of the courses, be interconnected to each other horizontally and vertically to reduce the size of audiences, to provide systematic support from the organization, to promote changes.

description: Strongly correlated electron systems require the development of new theoretical schemes in order to describe their unusual and unexpected properties. The usual perturbation schemes are inadequate and new concepts must be introduced. In our scheme of calculations, the Composite Operator Method, is possible to recover, through a self-consistent calculation, a series of fundamental symmetries by choosing a suitable Hilbert space.

description: Two internal hyperfine states of a Bose-Einstein condensate in a dilute magnetically trapped gas of ${}^{87}$Rb atoms are strongly coupled by an external field that drives Rabi oscillations between the internal states. Due to their different magnetic moments and the force of gravity, the trapping potentials for the two states are offset along the vertical axis, so that the dynamics of the internal and external degrees of freedom are inseparable. The rapid cycling between internal atomic states in the displaced traps results in an adiabatic transfer of population from the condensate ground state to its first antisymmetric topological mode. This has a pronounced effect on the internal Rabi oscillations, modulating the fringe visibility in a manner reminiscent of collapses and revivals. We present a detailed theoretical description based on zero-temperature mean-field theory.

description: In a recent communication, Weber and co-workers presented a surprising study on charge-localization effects in the N,N'-dimethylpiperazine (DMP+) diamine cation to provide a stringent test of density functional theory (DFT) methods. Within their study, the authors examined various DFT methods and concluded that "all DFT functionals commonly used today, including hybrid functionals with exact exchange, fail to predict a stable charge-localized state." This surprising conclusion is based on the authors' use of a self-interaction correction (namely, complex-valued Perdew-Zunger Self-Interaction Correction (PZ-SIC)) to DFT, which appears to give excellent agreement with experiment and other wavefunction-based benchmarks. Since the publication of this recent communication, the same DMP+ molecule has been cited in numerous subsequent studies as a prototypical example of the importance of self-interaction corrections for accurately calculating other chemical systems. In this correspondence, we have carried out new high-level CCSD(T) analyses on the DMP+ cation to show that DFT actually performs quite well for this system (in contrast to their conclusion that all DFT functionals fail), whereas the PZ-SIC approach used by Weber et al. is the outlier that is inconsistent with the high-level CCSD(T) (coupled-cluster with single and double excitations and perturbative triples) calculations. Our new findings and analysis for this system are briefly discussed in this correspondence.

Hydrodynamic Modeling Results Showing the Effects of the Luce Bayou Interbasin Transfer on salinity in Lake Houston, TX
Creators: name: Shah, Sachin

Publisher: name: Texas Water Journal
Year: 2020

description: An over-reliance on groundwater resources in the Houston (Texas) metropolitan area led to aquifer drawdowns and land subsidence, so regional water suppliers have been turning to surface water resources to meet water demand. Lake Houston, an important water supply reservoir 25 miles northeast from downtown Houston, requires new water supply sources to continue to meet water supply demands for the next several decades. The upcoming Luce Bayou Interbasin Transfer Project will divert up to 500 million gallons per day of Trinity River water into Lake Houston. Trinity River water has significantly different water quality than the Lake Houston tributaries. To evaluate the project's impact on water quality, the U.S. Geological Survey used an enhanced version of a previously released Lake Houston hydrodynamic model. With a focus on salinity and water-surface elevations, the model combined data from 2009-2017 with simulated flow from the Luce Bayou Interbasin Transfer to evaluate potential outcomes from three hypothetical flow scenarios. Overall, these scenarios found that the Luce Bayou Interbasin Transfer would cause salinities to rise over most of the modeled time (2009-2017), although salinities were buffered under 2011 drought conditions. Large inflow events equalized salinities under baseline conditions as well as the enhanced flow scenarios.

description: We compute the zero temperature phase diagram and the Hall response of the doped perovskite manganites within the model of double exchange and Jahn-Teller coupling, employing the large dimensionality approximation proposed by Millis et al. We find that in this scenario a ``hole - like'' $R_H$ for the hole doped manganites, as observed at low temperature by Matl et al., can be obtained only when lattice distortions persist in the metallic state at zero temperature. The calculated temperature dependence of $R_H$ seems to be consistent with the measured ``normal'' Hall coefficient in thin films.

description: Precise determinations of the masses of the $W$ boson and of the top quark could stringently test the radiative structure of the Standard Model (SM) or provide evidence for new physics. We analyze the excellent prospects at a muon collider for measuring $M_W$ and $m_t$ in the $W^+W^-$ and $t\bar t$ threshold regions. With an integrated luminosity of 10 (100) fb$^{-1}$, the $W$-boson mass could be measured to a precision of 20 (6) MeV, and the top-quark mass to a precision of 200 (70) MeV, provided that theoretical and experimental systematics are understood. A measurement of $Δm_t=200$ MeV for fixed $M_W$ would constrain a 100 GeV SM Higgs mass within about $\pm 2$ GeV, while $ΔM_W=6$ MeV for fixed $m_t$ would constrain $m_h$ to about $\pm 10$ GeV.

description: In the present work we used the method of semi-structured interview to investigate the views of educators and educational trainers concerning the training needs of teachers who deal with health education. The results showed that within these needs prominent arc those of acquiring the dexterity of team handling and of using energetic learning techniques. Educators have a reserve of experiences which with the appropriate handling by the educational trainer can be utilized. The method of experiential education comes first in the preferences of educators and trainers. The issue of continuous feedback is of great importance. Finally the connection between health education and counselling is observed. The training in health education contributes to both emotional and professional growth of teachers.

Coupled-Cluster Approach to Electron Correlations in the Two-Dimensional Hubbard Model

description: We have studied electron correlations in the doped two-dimensional (2D) Hubbard model by using the coupled-cluster method (CCM) to investigate whether or not the method can be applied to correct the independent particle approximations actually used in ab-initio band calculations. The double excitation version of the CCM, implemented using the approximate coupled pair (ACP) method, account for most of the correlation energies of the 2D Hubbard model in the weak ($U/t \simeq 1$) and the intermediate $U/t$ regions ($U/t \simeq 4$). The error is always less than 1% there. The ACP approximation gets less accurate for large $U/t$ ($U/t \simeq 8$) and/or near half-filling. Further incorporation of electron correlation effects is necessary in this region. The accuracy does not depend on the system size and the gap between the lowest unoccupied level and the highest occupied level due to the finite size effect. Hence, the CCM may be favorably applied to ab-initio band calculations on metals as well as semiconductors and insulators.

We show how naturally the zero-point energy emerges in the Planck black-body spectrum once symmetric in time motion - inherent in the Maxwell equations - is invoked for photons. Then, a detailed study is made of two-slit experiments for photons and some novel phenomena, amenable to experiments, are proposed, that arise due to the spin of the photon.

description: The purpose of this research was to investigate the conflict management styles of headteachers in Cyprus primary schools. It was decided that the descriptive research would be the best source for the first phase of the investigation. A mixed methods research was adopted for a dual purpose. Firstly, it aimed to develop the questionnaire. Secondly, it combined quantitative data of questionnaires with the qualitative data of semi-structured interviews, which created a more comprehensive investigation of the phenomenon that enhances the reliability and the validity of the research. The sample of the research consisted of 200 primary school headteachers who were randomly selected. The headteachers’ response rate came up to 67%. The research results indicate that headteachers prefer to adopt more the collaborating conflict management style rather than the avoiding style, which is rarely employed.

description: An "exact discretization" of the Schroedinger operator is considered and its direct and inverse scattering problems are solved. It is shown that a differential-difference nonlinear evolution equation depending on two arbitrary constants can be solved by using this spectral transform and that for a special choice of the constants it can be considered an integrable discretization of the KdV equation at large times. An integrable difference-difference equation is also obtained.

Shape tailoring to enhance and tune the properties of graphene nanomechanical resonators

description: The shape of a nanomechanical resonator profoundly affects its mechanical properties and determines its suitability for various applications, such as ultra-sensitive mass and force detection. Despite the promise of two-dimensional nanomechanical systems in such applications, full control over the shape of suspended two-dimensional materials, such as graphene, has not been achieved. We present an effective, single-step method to shape presuspended graphene into nanomechanical resonators with arbitrary geometries leading to enhanced properties in comparison to conventional drumheads. Our technique employs focused ion beam milling and achieves feature sizes ranging from a few tens of nanometers to several microns, while obtaining near perfect yield. We compare the mechanical properties of the shaped devices to unmodified drumheads, and find that low-tension, singlyclamped graphene cantilevers display a 20-fold increase in the mechanical quality factor (Q) with a factor 100 reduction in the mechanical damping. Importantly, we achieve these results while simultaneously removing mass, which enables state-of-the-art force sensitivity for a graphene mechanical resonator at room temperature. Our approach opens up a unique, currently inaccessible regime in graphene nanomechanics, one characterized by low strain, low frequency, small mass, and high Q, and facilitates tailoring of non-linearity and damping in mechanical structures composed of graphene and other 2D crystals.

description: The increasing use and spread of low carbon technologies are expected to cause new patterns in electric demand and set novel challenges to a distribution network operator (DNO). In this study, we build upon a recently introduced method, called "buddying", which simulates low voltage (LV) networks of both residential and non-domestic (e.g. shops, offices, schools, hospitals, etc.) customers through optimization (via a genetic algorithm) of demands based on limited monitored and customer data. The algorithm assigns a limited but diverse number of monitored households (the "buddies") to the unmonitored customers on a network. We study and compare two algorithms, one where substation monitoring data is available and a second where no substation information is used. Despite the roll out of monitoring equipment at domestic properties and/or substations, less data is available for commercial customers. This study focuses on substations with commercial customers most of which have no monitored `buddy', in which case a profile must be created. Due to the volatile nature of the low voltage networks, uncertainty bounds are crucial for operational purposes. We introduce and demonstrate two techniques for modelling the confidence bounds on the modelled LV networks. The first method uses probabilistic forecast methods based on substation monitoring; the second only uses a simple bootstrap of the sample of monitored customers but has the advantage of not requiring monitoring at the substation. These modelling tools, buddying and uncertainty bounds, can give further insight to a DNO to better plan and manage the network when limited information is available.

Flanders Electric bay 4 assembly routing and design
Creators: name: Price, Joseph
Publisher: name: Unknown
Year: 2013

description: Flanders Electric Bay 4 Assembly currently operates as the primary DC motor and
generator manufacturing area for the company. While it can form as necessary to fit
other needs such as repair services or specialty equipment production, this analysis
considers only the primary usage of the bay, which is the production of DC motors
and generators.
In order to reduce material handling, the following analysis and design report will
compare both the current and proposed operations of Bay 4 as well as discuss the
advantages of implementing a fixed process and product design. This analysis is
concerned with the current material handling at Flanders Electric in Bay 4. This
study will compare current operations to a proposed layout, which is specifically
designed to reduce travel time and the effects it has on production and cycle times.

description: Despite the fact that lately there has been an imperative demand for change and modernisation of Greek education and that Greek school should be open to society and its developments, the existing institutional and theoretical framework does not help the headmaster promote communication between the school and all types of the pupils’ parents. On the other hand, there is no research regarding the role of the headmaster in such communication. The results of the survey carried out with the majority of primary education headmasters in the Cyclades Islands, Greece, indicate clearly the limits and framework of communication and cooperation with the pupils’ families that headmasters arc now seeking. They also indicate that the overall service time of the headmaster and the service time of the headmaster in the same school are factors that substantially differentiate the headmaster's attitude towards the parents. Finally, the results suggest that such communication is a multidimensional procedure, which requires flexibility and knowledge on the part of the headmaster, as well as the application of various practices and communication strategies.

description: The study delves into Family Language Policy (FLP) within cross-cultural families with Korean and English L1 parents and their children in Australia and South Korea, a novel focus. Investigating language practices, it explores the interplay of internal and external factors on these families. With a mixed-methods approach, the research gathered 182 survey responses and conducted 50 interviews in both countries. Analysing data through the Interdisciplinary Framework of FLP, the study reveals that, regardless of their chosen FLP, Korean-English families in Australia and Korea prioritise English in communication, influenced significantly by English's societal status, irrespective of the country of residence. This study has contributed meaningfully to the field of FLP by shedding light on the complex experiences of cross-cultural families residing in two different countries.

description: The aim of this study was to explore teachers' self-reported attitudes and knowledge of the symptoms and different forms of child maltreatment, reporting incidents, personal perceptions toward the effect of television and internet, attitudes toward corporal punishment, and their beliefs about the prevention of the phenomenon.
The sample consisted of 105 teachers (aged 25-60 years) from 12 state primary schools in one county in the South East of Greece and one county in South of Cyprus, with differentiated socioeconomic status. Attitudes and knowledge about child maltreatment were assessed with a self-reported 19-items questionnaire that was developed by the research team.
Most teachers reported being aware of the signs and symptoms of child maltreatment, as well as reporting procedures. They also reported that television, internet and internet cafe contribute in the emergence of the violent behavior. They believe father is the more violent figure in the family. More teachers considered that the family house is the place where the most cases of violence take place. They supported that the most common forms of child abuse are the psychological and physical abuse. There arc differentiations in the opinions of Greek and Cypriot teachers.

description: This article aims at developing how teachers' perceptions and ideas about poetry and it's teaching are affected by the intellectual movement of Romanticism. Hour teachers' interviews are analyzed and interpreted using the method of content analysis and especially the paradigm of "structure". Teachers' romantic perceptions are focused on: a) poetry's idealization b) the combination between poetry and creative imagination c) poetry's connection with the feelings of the poet and d) the recognition of the dual poetry's value and especially the aesthetic value of poetry on one hand and the social-moral effect of poetry on the reader on the other. Content analysis demonstrated that the most prominent teachers' perception of the four is poetry's effect and influence on readers. The other aforementioned romantic ideas are connected with the dominant perception in so far as arising from this.

description: We have studied one-dimensional cellular automata with updating rules depending stochastically on the difference of the heights of neighbouring cells. The probability for toppling depends on a parameter lambda which goes to one with increasing slope, i.e. the dynamics can be varied continuously. We have investigated the scaling properties of the model using finite-size scaling analysis. A robust power-law behavior is observed for the probability density of the size of avalanches in a certain range of lambda values. The two exponents which determine the dependence of the probability density on time and system size both depend continuously on lambda, i.e. the model exhibits nonuniversal behavior. We also measured the roughness of the surface of the sandpile and here we obtained an universal behavior, i.e. a roughness exponent of about 1.75 for all values of lambda. For the temporal behavior of the mass a $f^{-ϕ}$ spectrum is obtained with an exponent phi close to 2 again for all lambda-values.
