Narrative and creation: intersubjectivity and negotiation of meaning in the interactive I – other experience
Creators: name: Sampaio, Juliano Casimiro De Camargo
name: Simão, Lívia Mathias
Publisher: name: Interacções
Year: 2013

description: This article presents an interdisciplinary discussion in the frontiers between Psychology and Performing Arts, as part of a research project focused on emerging narratives in the context of creative actions. We examined the negotiations of intra- and intersubjective meanings during I-other interactions, in which the subjects sought to create narratives, in the sense of the term laid out by Walter Benjamin. The Data corpus was formed by a set of video recordings of interactions between young people of 8 to 14 years of age, who were given the task of working together to write a dramatic text to be used in the preparation of a play or public presentations; also by notes taken by the researcher / director in a field notebook on the aforementioned process. Datum were analyzed and discussed from the perspective of Semiotic-Cultural Constructivism in Psychology (Simão, 2005, 2007b, 2010), allowing for an understanding of three simultaneous aspects in the act of narrating. These aspects then allowed for the creation of a model representing I-other negotiations, using the subjects to meet the demands of a consensual creative construction.

Family reminiscing and the construction of an autobiographical self
Creators: name: Fivush, Robyn
Publisher: name: Interacções

description: Narratives are the process and product of self-understanding. Following from both sociocultural and feminist theories, the ways in which we construct narratives of our past experiences is a critical site for the construction of a coherent sense of self and well-being. Substantial research has established individual differences in how families reminisce about the shared and intergenerational past, and relations between family reminiscing and children’s developing autobiographical narratives, self-concept and emotional well-being are well demonstrated. A review of the empirical research from preschool through adolescence indicates individual, gender and cultural differences in family reminiscing. Mothers are more elaborative and expressive than are fathers, both mothers and fathers are more elaborative and expressive with daughters than with sons, and independent cultures, such as European cultures, are more elaborative and expressive that interdependent cultures, such as Asian cultures.  Empirical relations and implications of these differences in family reminiscing for child self and well-being are discussed.

description: The goal of this work is to develop a phase-field fracture model capable of capturing mixed- mode fracture propagation behavior. In nature, failure of rocks and rock-like materials is usually accompanied by the propagation of mixed-mode fractures. To address this problem, some recent studies have incorporated mixed-mode fracture propagation criteria to the classic phase-field frac- ture model and proposed new energy splitting methods to split the total crack driving energy into mode-I and mode-II parts. But these new models have sometimes the shortcomings of being not numerically-robust or not physically sound. From a numerical viewpoint, they are all solved with staggered solution schemes. In this work, an existing energy splitting method for masonry-like materials is modified and incorporated into the phase-field model for mixed-mode fractures. A fully-monolithic scheme is used to solve the model. Therein, a primal-dual active set method is employed for treating the fracture irreversibility. Moreover, our computational framework uses adaptive mesh refinement of a predictor-corrector type and parallel computing to reduce the com- putation time. Three numerical tests are carried out, and the results of the new model are compared to those of existing models, demonstrating the numerical robustness and physical soundness of the new model. In total, six splitting methods are compared and computationally analyzed.

description: The great diversity of extrasolar planetary systems has challenged our understanding of how planets form, and how their orbits evolve as they form. Among the various processes that may account for this diversity, the gravitational interaction between planets and their parent protoplanetary disc plays a prominent role in shaping young planetary systems. Planet-disc forces are large, and the characteristic times for the evolution of planets orbital elements are much shorter than the lifetime of protoplanetary discs. The determination of such forces is challenging, because it involves many physical mechanisms and it requires a detailed knowledge of the disc structure. Yet, the intense research of the past few years, with the exploration of many new avenues, represents a very significant improvement on the state of the discipline. This chapter reviews current understanding of planet-disc interactions, and highlights their role in setting the properties and architecture of observed planetary systems.

Room Temperature Flux Pinning: A Gradient Lattice Approach to Bypassing Thermal Noise

Publisher: name: Zenodo
Year: 2025
Subjects: subject: flux pinning
subject: quantum coherence
subject: Quantum physics

description: This paper presents a theoretical framework for achieving flux pinning at room temperature through a gradient lattice design that overcomes thermal noise limitations. Conventional flux pinning typically requires superconducting temperatures to maintain stability of magnetic flux vortices against thermal fluctuations.We develop a mathematical model demonstrating how a geometric approach—utilizing a lattice with systematically varying edge lengths from center to periphery—can create sufficient pinning forces to achieve stability at 293K. Our numerical simulations indicate that a gradient design with a center edge length of 0.4 cm and outer edge length of 2.5 cm can generate average pinning forces of approximately ( 3.38 \times 10^{-5} ) N/m, with corresponding energy barriers significantly exceeding thermal energy.The geometric field concentration effect creates energy barriers that exceed room-temperature thermal energy by a factor of approximately ( 10^{10} ), indicating exceptional stability without requiring cryogenic cooling. This work provides a foundation for developing practical room-temperature applications of flux pinning, including levitation, precision positioning, and energy storage systems without requiring cryogenic cooling.

Dans notre pratique clinique, nous pensons qu'il est nécessaire d'intégrer un modèle plurifocal prenant en compte les problématiques d'attachement, de filiation et les modes d'alliance dans la famille. Nous envisageons aussi que ces vulnérabilités peuvent varier selon le genre et les modalités d'entrée en Protection de l'Enfance. Ainsi, nous illustrerons ces propos par la présentation de deux cas cliniques d'une jeune et d'un adolescent.

description: This research describes the management of Business Intelligence tools to evaluate the productive environment of an industrial trading company in Ecuador, specifically, within the safety category. The study was descriptive and evaluative with the presentation of a non-experimental and longitudinal cut design. From a census sample of 24 individuals (commercial, technical and managerial advisers), a data was obtained through direct observation and the application of a survey of closed dichotomous questions, with validity of content through expert judgment and a record of a good level of performance. reliability (α = 0.91; p <0.05), whose general analysis was carried out using the hypothetico-deductive method. The results reflected that only 58% of commercial intentions resulted in successful sales and, of the latter, 70% required at least two visits to customer facilities. Additionally, only 11% of the claims corresponded to the evaluated areas (logistics). By Business Intelligence it was possible to diagnose that the main non- conformities denoted interruptions in the company's transversal activities, as a result of the lack of established processes, management and performance indicators, also due to the lack of adequate technological tools. It was concluded that the company deserves a system aimed at optimizing the safety category, administrative, commercial and continuous improvement processes, in order to guarantee greater economic sustainability.

description: We study the quantum phase transition between a normal Bose superfluid to one that breaks additional Z_2 Ising symmetry. Using the recent shaken optical lattice experiment as an example, we first show that at mean-field level atomic interaction can significantly shift the critical point. Near the critical point, bosons can condense into a momentum state with high or even locally maximum kinetic energies due to interaction effect. Then, we present a general low-energy effective field theory that treats both the superfluid transition and the Ising transition in a uniform framework, and identify a quantum tricritical point separating normal superfluid, Z_2 superfluid and Mott insulator. Using perturbative renormalization group method, we find that the quantum phase transition belongs to a unique universality class that is different from that of a dilute Bose gas.

description: We consider a flat lattice of dipoles modeled by harmonic oscillators interacting with the electromagnetic field in dipole approximation. Eliminating the variables from the coupled equations of motion, we come to effective Maxwell equations. These allow for taking the lattice spacing $a$ to zero. As a result, we obtain reflection coefficients for the scattering of electromagnetic waves off the sheet. These are a generalization of that known from the hydrodynamic model. For instance, we get a non trivial scattering for polarizability perpendicular to the sheet. Also we show that the case of a sheet polarizable parallel to the sheet can be obtained in a natural way from a plasma layer of finite thickness. As an alternative approach we discuss the elimination of the electromagnetic fields resulting in effective equations for the oscillators. These show, for $a\to 0$, divergent behavior, resulting from the electrostatic interaction of the dipoles.

description: Este estudo buscou compreender como adolescentes com e sem experiência de gestação percebem a maternidade e o casamento/união. Foram realizadas entrevistas individuais semiestruturadas com nove adolescentes gestantes e dez adolescentes não gestantes de camadas populares, com idades entre 11 e 18 anos, residentes em uma cidade do interior do Rio Grande do Sul (Brasil). O estudo possui um delineamento qualitativo, no qual as informações coletadas foram submetidas à análise de conteúdo temática. Os resultados mostram que tanto as jovens gestantes quanto as não gestantes pensam na maternidade como um acontecimento positivo. O desejo de ser mãe parece ser influenciado pelas expectativas sociais sobre o que é ser adolescente e ser mãe. Na visão das jovens, o casamento baseia-se no amor e na divisão de responsabilidades. As adolescentes não gestantes parecem priorizar a inserção no mercado de trabalho, estabilidade financeira e a formação de um relacionamento afetivo antes da maternidade. Para elas, a maternidade deveria ocorrer somente após o casamento/união, sendo resultado de uma relação amorosa estável e com o objetivo de formar um novo núcleo familiar. Já para as adolescentes gestantes, a maternidade não viria, necessariamente, associada ao estabelecimento de um relacionamento estável, sendo que esse fenômeno pode inclusive  motivar o casamento e a formação de uma nova família.

description: We detect the second known lambda Bootis star (HD 54272) which exhibits gamma Doradus-type pulsations. The star was formerly misidentified as a RR Lyrae variable. The lambda Bootis stars are a small group (only 2 per cent) of late B to early F-type, Population I stars which show moderate to extreme (up to a factor 100) surface underabundances of most Fe-peak elements and solar abundances of lighter elements (C, N, O, and S). The photometric data from the Wide Angle Search for Planets (WASP) and All Sky Automated Survey (ASAS) projects were analysed. They have an overlapping time base of 1566 d and 2545 d, respectively. Six statistically significant peaks were identified (f1 = 1.410 116 c/d, f2 = 1.283 986 c/d, f3 = 1.293 210 c/d, f4 = 1.536 662 c/d, f5 = 1.157 22 c/d and f6 = 0.226 57 c/d). The spacing between f1 and f2, f1 and f4, f5 and f2 is almost identical. Since the daily aliasing is very strong, the interpretation of frequency spectra is somewhat ambiguous. From spectroscopic data, we deduce a high rotational velocity (250+-25 km/s) and a metal deficiency of about -0.8 to -1.1 dex compared to the Sun. A comparison with the similar star, HR 8799, results in analogous pulsational characteristics but widely different astrophysical parameters. Since both are lambda Bootis-type stars, the main mechanism of this phenomenon, selective accretion, may severely influence gamma Doradus-type pulsations.

description: Suppose that $c(x,y)$ is the cost of transporting a unit of mass from $x\in X$ to $y\in Y$ and suppose that a mass distribution $μ$ on $X$ is transported optimally (so that the total cost of transportation is minimal) to the mass distribution $ν$ on $Y$. Then, roughly speaking, the Kantorovich duality theorem asserts that there is a price $f(x)$ for a unit of mass sold (say by the producer to the distributor) at $x$ and a price $g(y)$ for a unit of mass sold (say by the distributor to the end consumer) at $y$ such that for any $x\in X$ and $y\in Y$, the price difference $g(y)-f(x)$ is not greater than the cost of transportation $c(x,y)$ and such that there is equality $g(y)-f(x)=c(x,y)$ if indeed a nonzero mass was transported (via the optimal transportation plan) from $x$ to $y$. We consider the following optimal pricing problem: suppose that a new pricing policy is to be determined while keeping a part of the optimal transportation plan fixed and, in addition, some prices at the sources of this part are also kept fixed. From the producers' side, what would then be the highest compatible pricing policy possible? From the consumers' side, what would then be the lowest compatible pricing policy possible? In the framework of $c$-convexity theory, we have recently introduced and studied optimal $c$-convex $c$-antiderivatives and explicit constructions of these optimizers were presented. In the present paper we employ optimal $c$-convex $c$-antiderivatives and conclude that these are natural solutions to the optimal pricing problems mentioned above. This type of problems drew attention in the past and existence results were previously established in the case where $X=Y=R^n$ under various specifications. We solve the above problem for general spaces $X,Y$ and real-valued, lower semicontinuous cost functions $c$.

description: We consider the homothetic motion group. We construct a homothetic covariant Newtonian gravitation theory which unifies inertial homothetic forces and gravitational fields. This is achieved through an equivalence principle based on a local homothetic frame of motion. As a consequence, we can obtain a coherent Newtonian cosmology which admits a cosmological principle and leads to the Friedman equations for a dust universe. Finally we prove that this gravity theory can be obtained as the non-relativistic limit of a class of metrics in General Relativity. The Friedmann-Lema\^ıtre-Robertson-Walker (FLRW) metric and its limit are also studied.

description: Objetivou-se verificar o uso do preservativo nas atividades sexuais de adolescentes de escolas públicas e privadas de um município da Zona da Mata de Minas Gerais, Brasil. Pesquisa com abordagem quantitativa de caráter exploratório‑descritivo realizada em 2012, com 269 participantes, utilizando-se de um questionário autoaplicado. Os resultados mostram que a maior parte é do sexo feminino (88%). Quanto à idade, 73% estão na faixa de 13 a 18 anos e 58% cursavam o ensino fundamental. Referiram ter informações a respeito dos métodos preventivos de gravidez e doenças sexualmente transmissíveis 80%. A ocorrência da primeira relação sexual aconteceu para 27% dos participantes na faixa etária de 13 a 15 anos. O método contraceptivo usado com maior frequência foi a camisinha masculina (58% dos meninos da escola privada e 84% dos que estudam em escola pública). Um percentual reduzido de adolescentes referiu associar o uso da camisinha com a pílula anticoncepcional. Evidencia-se que foi considerável a quantidade de adolescentes que não utilizaram o preservativo na primeira relação (30%) e daqueles em atividade sexual que não recorreram ao serviço de saúde para buscar informações preventivas (75%). Este contexto motiva os profissionais de saúde a sensibilizarem os adolescentes para considerarem o serviço de saúde e seus profissionais como suporte ao desenvolvimento de competências que os tornem capazes de tomar decisões e resolver os problemas relativos aos relacionamentos sexuais, adotando métodos seguros em relação à prevenção de gravidez e DSTs, exercendo a vigilância da saúde.

Objetivou-se determinar neste grupo o padrão de consumo de álcool e fatores que contribuem para esse comportamento. Estudo transversal, descritivo, observacional, abordagem quantitativa realizada com inquérito domiciliar, em 2010 e 2011, em dois assentamentos em Juiz de Fora, Minas Gerais, Brasil. Entre os adolescentes o padrão de consumo do álcool é alto; os dados apontam que no sexo masculino há maior consumo de álcool; quanto à cor/etnia, os adolescentes de cor negra foram os que apresentaram níveis maiores de abuso de álcool, seguidos dos pardos. Os adolescentes são de famílias de baixa renda, a maioria é criada sem os pais, o que lhes proporciona um ambiente familiar desestruturado, propiciando ainda mais o uso abusivo de álcool. Destaca-se a educação ambiental como uma forma abrangente de intervenção que vai além daquela que atinge apenas os fatores da dependência enquanto doença. A educação concentrada nos sujeitos, em sua relação com o meio ambiente, pode constituir ações preventivas de danos à saúde, repercutindo na qualidade de vida das pessoas. Pode-se afirmar que a integração saúde-escola, ao trabalhar as causas ambientais, está se direcionando ao desenvolvimento sustentável, em prol de uma melhor qualidade de vida, adequada a todas as espécies para preservar gerações futuras.

description: We present a theoretical first-principles method to calculate the free energy of a magnetic system in its high-temperature paramagnetic phase, including vibrational, electronic, and magnetic contributions. The method for calculating free energies is based on ab-initio molecular dynamics and combines a treatment of disordered magnetism using disordered local moments molecular dynamics (DLM-MD) with the temperature dependent effective potential (TDEP) method to obtain the vibrational contribution to the free energy. We illustrate the applicability of the method by obtaining the anharmonic free energy for the paramagnetic cubic and the antiferromagnetic orthorhombic phases of chromium nitride. The influence of lattice dynamics on the transition between the two phases is demonstrated by constructing the temperature-pressure phase diagram.

description: Este texto apresenta reflexões iniciais sobre a configuração afetiva do relacionamento entre o adolescente que cometeu ato infracional de natureza social e sua mãe, e entre o adolescente que cometeu ato infracional de natureza sexual contra crianças e adolescentes, e sua mãe. Essas reflexões se baseiam em observações realizadas em uma pesquisa-intervenção na qual a coleta das informações ocorreu durante a realização de intervenções psicossociais grupais com adolescentes que apresentam essas duas problemáticas. O referencial teórico da Psicossociologia, em especial o método de História de Vida surge com o desejo de ampliar o olhar sobre o tema dos adolescentes que cometeram atos infracionais. Complementamos o referencial com a Socionomia e o Pensamento Sistêmico. As informações foram discutidas ainda na perspectiva da abordagem de D. W. Winnicott. Realizaram-se dois grupos de intervenção psicossocial: um com adolescentes que cometeram ato infracional social e que cumpriam medida socioeducativa de Liberdade Assistida – LA, e um grupo multifamiliar com adolescentes que cometeram ato infracional de natureza sexual em uma unidade de referência pública para atendimento a crianças e adolescentes. Esses dois contextos situaram-se no Distrito Federal, Brasil. A partir desses encontros iniciamos um estudo exploratório no sentido de mapear as diferenças de relacionamento entre as mães e os adolescentes desses dois grupos.  Apesar das muitas particularidades desse relacionamento, observamos que as mães não conseguem ser suficientemente boas, ou porque não conseguiram se devotar ao filho (ato infracional de natureza sexual) ou porque estabeleceram uma relação de extremo devotamento ao filho, não conseguindo deixá-lo desenvolver a sua autonomia (ato infracional social).

In this work, we study the implications of this at the ILC with polarized beams for signals that go beyond traditional anomalous triple neutral gauge boson couplings. Here we report a dimension-8 CP-conserving $Z γZ$ vertex that has not found mention in the literature. We carry out a systematic study of the anomalous couplings in general terms and arrive at a classification. We then obtain linear-order distributions with and without CP violation. Furthermore, we place the study in the context of general BSM interactions represented by $e^+e^- Z γ$ contact interactions. We set up a correspondence between the triple gauge boson couplings and the four-point contact interactions. We also present sensitivities on these anomalous couplings, which will be achievable at the ILC with realistic polarization and luminosity.

description: A violência escolar, em particular o bullying, constitui uma espécie de «nó cego» para as comunidades educativas e, de modo geral, para a sociedade. Na lógica de uma compreensão contextual e profunda da vida escolar de adolescentes, desenvolvemos um estudo sensível às especificidades das interações entre pares, direta ou indiretamente relacionadas com manifestações de bullying. Nesta perspetiva, pretendemos verificar se o género masculino, enquanto catalisador preferencial destas abordagens agressivas, mantém nos dias de hoje, o seu status de bullying face ao género feminino. Descrevemos e analisámos a prevalência das múltiplas formas de vitimação ocorridas entre pares, através de um questionário aplicado a 360 alunos do 7º ano do ensino básico, sendo 168 (46,7%) do género feminino e 192 (53,3%) do masculino, com idades compreendidas entre os 11 e os 16 anos (X =12,36 e + = 0,773). Os principais achados da pesquisa indicam não haver diferenças de género, estatisticamente significativas, com exceção aos tipos de vitimação física e de exclusão. Decorre dessa constatação, no confronto com outras que, da mesma forma, emergem dos esforços para desvelar a realidade educativa das crianças e jovens, que compõem o corpo de alunos da escola pública portuguesa, o indicativo de uma necessidade inadiável: garantir, pela vigência plena das próprias funções da escola, o direito à participação e à autonomia, no que se afirmam diferentes dimensões da cidadania, dessas categorias sociais geracionais.

description: We present a Monte-Carlo study of the liquid-vapor transition and the critical behavior of a model of polyelectrolytes with soft gaussian charge distributions introduced recently by Coslovich, Hansen, and Kahl [J. Chem. Phys. \textbf{134}, 244514 (2011)]. A finite size study involving four different volumes in the grand canonical ensemble yields a precise determination of the critical temperature, chemical potential, and density of the model. Attempts to determine the nature of the criticality and to obtain reliable values for the critical exponents are not conclusive.

description: We present the observational results of this kind of rare object 1SWASP J093010.78+533859.5, for which the doubly eclips- ing feature had been detected previously from the SuperWASP photometric archive. Individual PSF photometry for two objects with a separation of about 1.9 arcsec was performed for the first time in this study. Our time-series photometric data confirms the finding of Lohr et al. (2013) that the bright object A is an Algol-type detached eclipsing binary and the fainter B is a W UMa-type contact eclipsing. Using the high- resolution optical spectra, we obtained well-defined radial velocity variations of system A. Furthermore, stationary spectral lines were detected that must have originated from a further, previously unrecognized stellar component. It was confirmed by the third object contribution from the light curve analysis. No spectral feature of the system B was detected, probably due to motion blur by long exposure time. We obtained the binary parameters and the absolute dimensions of the systems A and B from light curve synthesis with and without radial velocities, respectively. The primary and secondary components of system A have a spectral type of K1 and K5 main sequences, respec- tively. Two components of system B have nearly the same type of K3 main sequence. Light variations for both binaries are satisfactorily modeled by using two-spot models with one starspot on each component. We estimated the distances to systems A and B individually. Two systems may have similar distances of about 70 pc and seem to be gravitationally bound with a separation of about 130 AU. In conclusion, we suggest that 1SWASP J093010.78+533859.5 is a quintuple stellar system with a hierarchical structure of a triple system A(ab)c and a binary system B(ab).

Os SMS em alunos do 2º e do 3º ciclos. Ameaça ou triunfo face aos normativos legais? Um estudo de caso

Publisher: name: Interacções

description: O artigo que se apresenta tem por objectivo analisar sms de alunos que frequentam os 2º e 3º ciclos do Ensino Básico, procurando averiguar em que medida os seus registos escritos se distanciam, em termos lexicais e ortográficos, dos registos normativizados por dicionários e gramáticas. Para identificar essas alterações, irá adoptar-se uma metodologia de tipo etnográfico, tendo por base um estudo de caso, em que se efectuará uma comparação entre os sms escritos por alunos de ambos os ciclos de ensino. A análise terá o seu foco no tipo de vocabulário utilizado por um aluno do 2º ciclo e por um aluno do 3º ciclo e tentar-se-á mostrar que há tendência de aproximação entre a oralidade e a escrita e que a utilização da escrita logográfica é uma realidade escolar. Sublinha-se, também, o facto de não se considerar este contexto de escrita uma ameaça para as “gramáticas oficiais”.

description: We develop a numerical method to calculate the Bethe logarithm for resonant states. We use the Complex Coordinate Rotation (CCR) formalism to describe resonances as time-independent Schrödinger solutions. To get a proper expression for the Bethe logarithm we apply the generalization of the second order perturbation theory to an isolated CCR eigenstate. Using the developed method we perform a systematic calculation of the Bethe logarithm for metastable states in the antiprotonic helium He$^+\bar{p}\,$ atoms with precision of 7--8 significant digits. We also recalculate the nonrelativistic energies with improved precision using CODATA10 recommended values of masses. Along with a complete set of corrections of $mα^7$ order and the leading contributions of $mα^8$ order that has allowed us to get new theoretical values for ro-vibrational transition frequencies for the He$^+\bar{p}$ atoms with uncertainty of 0.1--0.3 MHz.

description: The UμνSSM is a U(1)' extension of the μνSSM supersymmetric model, where baryon-number-violating operators as well as explicit mass terms are forbidden, and the potential domain wall problem is avoided. The gauge anomaly-cancellation conditions impose the presence of exotic quark superfields in the spectrum of UμνSSM models, and allow the presence of several singlet superfields under the standard model gauge group, in addition to the right-handed neutrino superfields. The gauge structure implies an additional discrete Z $_{2}$ symmetry in the superpotential, ensuring the stability of a singlet which behaves as WIMP dark matter without invoking R-parity. We analyze this novel possibility in detail, using the fermionic component of the singlet as the dark matter candidate. In particular, we compute its amount of relic density via Z', Higgs-right sneutrino and dark matter mediated annihilations, and its potential signals in dark matter direct detection experiments. The constraints on the parameter space due to Z'; direct searches at the LHC are imposed in the analysis, as well as those from the hadronization inside the detector of the exotic quarks. Large regions of the parameter space turn out to be in the reach of the upcoming Darwin experiment.
A Silicon Nanocrystal Tunnel Field Effect Transistor

description: In this work, we demonstrate a silicon nanocrystal Field Effect Transistor (ncFET). Its operation is similar to that of a Tunnelling Field Effect Transistor (TFET) with two barriers in series. The tunnelling barriers are fabricated in very thin silicon dioxyde and the channel in intrinsic polycrystalline silicon. The absence of doping eliminates the problem of achieving sharp doping profiles at the junctions, which has proven a challenge for large-scale integration and in principle allows scaling down the atomic level. The demonstrated ncFET features a 10$^4$ on/off current ratio at room temperature, a low 30 pA/$μ$m leakage current at a 0.5 V bias, an on-state current on a par with typical all-Si TFETs and bipolar operation with high symmetry. Quantum dot transport spectroscopy is used to assess the band structure and energy levels of the silicon island.

description: We suggest a method of introducing the Gribov--Zwanziger horizon functional, $H$, for Yang--Mills theories by using the composite fields technique: $σ(ϕ)=H$. A different form of the same horizon functional in gauges $χ$ and $χ^{\prime }$ is taken into account via (gauged) field-dependent BRST transformations connecting quantum Yang--Mills actions in these gauges. We introduce generating functionals of Green's functions with composite fields and derive the corresponding Ward identities. A study of gauge dependence shows that the effective action in Yang--Mills theories with the composite field $H$ does not depend on the gauge on the extremals determined by the Yang--Mills fields $ϕ$ alone.

description: Este trabalho analisa o primeiro volume da Coleção As aventuras do Capitão Cueca, objetivando identificar motivos do seu sucesso de público e vendagem. Do ponto de vista sociológico, a história reflete inconsistências entre as mudanças da sociedade e da instituição escolar, bem como a abreviação da infância e a extensão da adolescência. A busca de protagonismo pelos alunos choca-se com a tradição da educação tradicional, tantas vezes “bancária”. Do ponto de vista linguístico, busca-se explicar os erros ortográficos intencionais, bem como identificar a metáfora conceptual e a recorrência de verbos de ação utilizados na construção dos personagens. Conclui‑se que a heterodoxia dos recursos gráficos e do enredo atrai os leitores, aos quais se reserva papel ativo e crítico na leitura, despertando o seu desejo pela leitura.
