description: No presente trabalho pretendeu-se avaliar o efeito de três humidades relativas (HR) (60, 70 e 80%) nas características físico-químicas e microbiológicas de miolo de amêndoa, armazenado a 25 °C, durante 60 dias. Em relação à atividade da água, os menores valores foram observados para a HR de 60%, após 1 e 2 meses (0,624 e 0,595, respetivamente), ao contrário da HR de 80%, para a qual não se observaram diferenças significativas ao longo do tempo. Relativamente aos parâmetros nutricionais, para cada HR ao longo do tempo, não se observaram diferenças significativas. Ao comparar as HRs entre si, as únicas diferenças significativas foram detetadas no teor de humidade após 30 dias (menores valores para 60%) e para a proteína após 60 dias (menores valores para 70%). Salvo raras exceções, não se observaram diferenças significativas nos tempos de indução, tanto para o fruto como para o óleo, para as três HRs. Quanto à qualidade microbiológica, verificou-se um decréscimo significativo nos microrganismos a 30 °C após 60 dias, em relação ao início. Pelo contrário, nos bolores e leveduras não se observaram diferenças significativas. Em conclusão, as HRs estudadas não afetaram de forma relevante a qualidade final de miolo de amêndoa durante 60 dias de armazenamento.

Cosmarium margigranulatum

description: Cosmarium margigranulatum F.M. Costa & C.W.N.Moura sp. nov. (Figs. 3, 15–18)
 Diagnosis: —Cells as long as broad, median constriction deep, sinus closed, linear; semicells reniform, smooth median face, angles rounded covered by granules, apex slightly projected with three protrusions; cell oblong in apical view. Cell dimensions: length 36.8–41.3 μm, breadth 41.6–44.6 μm, breadth of isthmus 12.7–16.2 μm.
 Holotype:— Material numbered (HUEFS 263036!) [pro parte], deposited at the Herbarium of the State University of Feira de Santana, population partially illustrated here (Figs. 3, 15–18).
 Paratypes:— Material numbered (HUEFS 263040) [pro parte], deposited at the Herbarium of State University of Feira de Santana.
 Type locality:— BRAZIL. Bahia: Camaçari, Camaçari-Mirim River, Lat. 12°42’23.1’’ S, Long. 38°15’27.2’’ W, 29 November 2019, F. M. Costa & J. T.X. Neto s/n (HUEFS 263036).
 Habitat:— Periphytic on Eleocharis acutangula; water conductivity 0.04 mS. cm-1 (± 0.01); dissolved oxygen 7.6 mg.L- 1 (± 0.1); pH 7.3 (± 0.9); total dissolved solids 0.02 ppt (± 0.01); water temperature 28.3 ºC (± 1.3).
 Etymology:— The specific epithet refers to the ornamentation composed of various granules located at the margins of semicells.
 Differential diagnosis:— Cosmarium margigranulatum differs from the other species of Cosmarium by having a very distinct ornamentation: concentrated granules along the margins of the semicells, but lacking in the central region.
 Morphologically, the newly described species resembles Cosmarium ornatum var. pseudolagoense Förster (1964: 399). However, this latter variety differs by having a concentric ring of granules on the face of the semicells and short spines at the angles of the semicells.

description: We develop a procedure for detecting Fermi liquid instabilities by extending the analysis of Pomeranchuk to two-dimensional lattice systems. The method is very general and straightforward to apply, thus providing a powerful tool for the search of exotic phases. We test it by applying it to a lattice electron model with interactions leading to $s$ and d-wave instabilities.

description: Using first principle electronic structure calculations we investigated the role of substitutional doping of B,N,P,Al and vacancies (${\cal V}$) in diamond (X$_α$C$_{1-α}$). In the heavy doping regime, at about $\sim 1-6%$ doping an impurity band appears in the mid gap. Increasing further the concentration of the impurity substitution fills in the gap of the diamond host. Our first principle calculation indicates that in the case of vacancies, a clear single-band picture can be employed to write down an effective {\em one band} microscopic Hamiltonian, which can be used to further study various many-body and disorder effects in impurity band (super)conductors.

description: O presente trabalho teve como objetivo caracterizar físico-quimicamente 10 variedades de amêndoa (Francesas, Espanholas e Portuguesas), colhidas na região de Trás-os-Montes. Sob o ponto de vista físico, verificou-se que a variedade Portuguesa “Duro Italiano” foi aquela que apresentou os frutos com menor massa (2,59 ± 1,08 g) e largura = 18,68 ± 2,09 mm. Pelo contrário, as variedades Ferraduel (Francesa), Marinada (Espanhola) e Pegarinhos (Portuguesa) foram as que apresentaram maiores frutos. Em relação à composição nutricional, verificou-se uma grande variação nos teores de humidade (3,80 ± 0,27 a 30,59 ± 0,29 g/100g matéria fresca (m.f.), correspondente às variedades Vayro (Espanhola) e Ferraduel, respetivamente), provavelmente devido a diferentes períodos de colheita e tempos de secagem aplicados pelos produtores. Não foram observadas diferenças significativas entre as variedades analisadas no que se refere à gordura, com a exceção da Ferraduel, possivelmente resultado da colheita precoce desta variedade. Os valores de proteína e cinzas variaram entre 12,03-17,64 e 2,34-3,51 g/100g m.f., respetivamente. No que diz respeito à estabilidade oxidativa do fruto, não se observaram diferenças significativas. Como conclusão geral, as variedades analisadas (estrangeiras e Portuguesas) não se distinguiram de forma evidente entre elas, sendo necessário, no futuro, realizar mais estudos em relação a outros parâmetros.

description: Based on the dimension of degeneracy, topological electronic systems can roughly be divided into three parts: nodal point, line and surface materials corresponding to zero-, one- and two-dimensional degeneracy, respectively. In parallel to electronic systems, the concept of topology was extended to phonons, promoting the birth of topological phonons. Till date, few nodal point, line and surface phonons candidates have been predicted in solid-state materials. In this study, based on symmetry analysis and first-principles calculation, for the first time, we prove that zero-, one- and two-dimensional degeneracy co-exist in the phonon dispersion of one single realistic solid-state material SnO$_2$ with \textit{P}4$_2$/\textit{mnm} structure. In contrast to the previously reported electronic systems, the topological phonons observed in SnO$_2$ are not restricted by the Pauli exclusion principle, and they experience negligible spin-orbit coupling effect. Hence, SnO$_2$ with multiple dimensions of degeneracy phonons is a good platform for studying the entanglement among nodal point, line and surface phonons. Moreover, obvious phonon surface states are visible, which is beneficial for experimental detection.

description: Nos últimos anos assistiu-se a uma transformação no modelo de cultivo da amendoeira influenciada pela valorização do fruto, as novas cultivares autoférteis e a introdução do regadio. Apesar do Alentejo não ter tradição na produção de amêndoa, o regadio levou a apostar-se na intensificação da cultura, com diferentes sistemas de condução. Todavia, o desafio é grande perante a falta de experiência e elevada estrutura de encargos associadas ao modelo superintensivo. Nesta perspetiva, o objetivo deste trabalho é comparar o desenvolvimento das amendoeiras ’Soleta’ e ‘Lauranne’ enxertadas em ‘Rootpac 20’ e plantadas em sistema superintensivo (5´1,5 m), quando conduzidas em eixo vertical, palmeta de três eixos e sebe. Avaliou-se a área de secção do tronco, a quantidade de lenha de poda e as produtividades, bem como a qualidade da amêndoa obtida. Embora os resultados sejam preliminares, as ‘Lauranne’ conduzidas em eixo foram as que cresceram mais e das quais foi retirada maior quantidade de lenha de poda. As ’Soleta’ tendem a produzir mais em eixo do que em sebe, já as ‘Lauranne’ foram mais produtivas quando conduzidas em palmeta. A forma de condução não afetou a qualidade comercial da amêndoa. Os resultados sugerem que a condução das árvores afeta o seu comportamento produtivo em regime superintensivo, que varia com a cultivar.

description: A amendoeira possui uma grande importância económica, ambiental, cultural e social em Portugal. Esta espécie chega mesmo a ser uma das principais fontes de rendimento em algumas regiões, como a Terra Quente Transmontana e caracterizadora da paisagem. O consumo nacional de amêndoa tem acompanhado a tendência mundial, registando um aumento nos últimos anos, resultante da tomada de consciência da importância de um estilo de vida e hábitos alimentares mais saudáveis, sendo que entre 2005 e 2017 praticamente duplicou. Com o presente estudo pretende-se contribuir para o conhecimento mais pormenorizado do setor da amêndoa. Assim, analisa-se a evolução deste setor a nível nacional, retratando a produção, comercialização, consumo e comércio externo da amêndoa. Este estudo abarca o período 2005-2019 e tem por base múltipla informação estatística, complementada com outras fontes secundárias. Da análise aos dados constata-se que em Portugal se registou um aumento de 34% da área de produção de amêndoa, entre 2009 e 2019. Também a produção nacional, entre 2009 e 2018, aumentou cerca de 34%.

description: O conhecimento da artropodofauna das culturas (fitófagos, predadores, parasitoides e indiferentes) e das relações existentes entre si é fundamental numa perspetiva de conservação da fauna auxiliar, de promoção da proteção biológica contra as principais pragas e de manutenção da cultura em bom estado fitossanitário. No caso da amendoeira, o conhecimento acerca da biologia das pragas-chave, a sua dinâmica populacional e os predadores e parasitoides associados é ainda escasso em Portugal. Assim, este trabalho teve por objetivo conhecer a riqueza e abundância dos artrópodes associados ao amendoal e, em particular, os potenciais predadores e parasitoides. Nesse sentido, entre abril e início de outubro de 2018 e 2019, semanalmente, realizou-se a técnica das pancadas em 25 árvores (2 ramos por árvore e duas batidas/ramo) selecionadas aleatoriamente num amendoal localizado em Alfandega da Fé. O material colhido foi separado e os artrópodes existentes contados e identificados ao mais baixo nível taxonómico possível (ordem, família, género ou espécie). Os resultados obtidos mostram a existência de uma grande abundância e diversidade de artrópodes. No que respeita aos auxiliares, por ordem de importância relativa e respetivamente em 2018 e 2019, surgiram as aranhas com 14% e 20%, os coccinelídeos com 6,5% e 2,6%, os himenópteros parasitoides com 3,0% e 7,1% e os crisopídeos com 0,6% e 1,8%. Os himenópteros parasitoides e os coccinelídeos surgiram em maior número no período de maio a julho, coincidente com a presença de estados imaturos de diferentes pragas do amendoal, como os afídeos, larvas de lepidópteros e monosteira.

description: We consider the Mielke-Baekler model of three-dimensional AdS gravity with torsion, which has gravitational and translational Chern-Simons terms in addition to the usual Einstein-Hilbert action with cosmological constant. It is shown that the topological nature of the model leads to a finite Fefferman-Graham expansion. We derive the holographic stress tensor and the associated Ward identities and show that, due to the asymmetry of the left- and right-moving central charges, a Lorentz anomaly appears in the dual conformal field theory. Both the consistent and the covariant Weyl and Lorentz anomaly are determined, and the Wess-Zumino consistency conditions for the former are verified. Moreover we consider the most general solution with flat boundary geometry, which describes left-and right-moving gravitational waves on AdS_3 with torsion, and shew that in this case the holographic energy-momentum tensor is given by the wave profiles. The anomalous transformation laws of the wave profiles under diffeomorphisms preserving the asymptotic form of the bulk solution yield the central charges of the dual CFT and confirm the results that appeared earlier on in the literature. We finally comment on some points concerning the microstate counting for the Riemann-Cartan black hole.

description: A amendoeira é um elemento característico da paisagem em algumas regiões de Portugal como Trás-os-Montes onde a espécie tem grande importância económica. Nesta região concentra-se a maior área plantada do País, com 19800 ha (58% da área nacional) e 80% da produção de amêndoa em casca (16200 ton), em 2018. A monosteira, Monosteira unicostata (Mulsant & Rey, 1852) (Heteroptera: Tingidae), é considerada a praga mais importante no amendoal tradicional e intensivo. Este inseto hiberna como adulto em locais abrigados e na Primavera, alimenta-se das folhas, desenvolvendo 2 a 4 gerações dependendo das condições ecológicas da região/ano/pomar. Os estragos ocasionados podem ser diretos e resultam da picada nas folhas provocando o esvaziamento celular e descoloração, e indiretos pela deposição de excreções do inseto na página inferior da folha. Ambos os processos reduzem e dificultam a fotossíntese e as trocas gasosas, resultando num precoce envelhecimento e queda da folha e consequentemente redução da produção. O conhecimento da bioecologia da praga e a correta estimativa do risco são fundamentais para uma tomada de decisão fitossanitária consciente. Neste sentido, os objetivos deste trabalho foram monitorizar os diferentes estados de desenvolvimento de M. unicostata num amendoal de Trás-os-Montes e avaliar os estragos. Para o efeito, entre abril e setembro em 2018 e 2019, num amendoal de Alfandega da Fé, semanalmente procedeu-se à colheita de 20 folhas em cada uma de 20 árvores, que foram observadas à lupa binocular para registo do número de posturas, ninfas e adultos de M. unicostata bem como dos estragos visíveis nas folhas. Paralelamente, também com periodicidade semanal, realizou-se a técnica das pancadas. As ninfas foram observadas a partir de final de junho, com um máximo de 0,62±1,35 ninfas/amostragem em 2018 e 0,39±1,46 ninfas/amostragem em 2019. Quanto aos adultos, observou-se o máximo em meados de agosto com 0,07±0,38 adulto/amostragem em 2018 e 0,04±0,20 adultos/amostragem em 2019. Os resultados obtidos na técnica das pancadas confirmam os observados nas folhas, com registo de ninfas e adultos entre meados de maio e setembro. Os níveis populacionais mais elevados registaram-se entre agosto e setembro, com aproximadamente 8 exemplares/amostra. A percentagem de folhas com estragos ocasionados pela monosteira aumentou ao longo do ano, ultrapassando os 70% para ambos os anos.

description: In this paper, we report the first extended GeV $γ$-ray emission, at a significant level of $\sim$ 8.13$σ$, from the region of the supernova remnant (SNR) SNR G317.3-0.2 by analyzing $\sim$ 12.2 years of Fermi Large Area Telescope (Fermi-LAT) Pass 8 data in the work. The best-fit position of the new $γ$-ray source matches that of the 843 MHz radio energy band of SNR G317.3-0.2, and there is no significant variability of the photon flux of the corresponding light curve (LC) in the data for the 12.2 year period; therefore, by excluding other known $γ$-ray sources or candidates within a 2$σ$ error radius from the best-fit position of SNR G317.3-0.2, we suggest that the $γ$-ray source is likely to be a GeV counterpart of SNR G317.3-0.2.

description: A cultura da nogueira (Juglans regia L) para exploração do fruto tem sido, recentemente em Portugal, alvo dos interesses de vários empresários agrícolas. Cremos que este fenómeno ocorre pelo reconhecimento dos interesses de mercado. Estes, por sua vez, estão essencialmente associados às características organoléticas da noz, a qual, enquanto elemento da dieta alimentar humana, tem vindo a ser alvo de um reconhecimento crescente nos últimos anos, tanto por força do aumento da capacidade de análise dos constituintes do fruto como pelo conhecimento dos efeitos que estes podem exercer na saúde. Neste contexto, contribui ainda a favor da cultura da nogueira a grande diversidade de utilização dos seus produtos, além da alimentação humana, designadamente na indústria farmacêutica, no fabrico de corantes, de licores e ainda na indústria da madeira e seus transformados. O presente estudo desenvolve-se em torno da análise dos dados oficialmente disponíveis, no sentido de elaborar um quadro informativo dos principais elementos caracterizadores dos aspetos produtivos e comerciais da nogueira/noz, no panorama mundial e nacional, identificando-se tendências e tentar contribuir para a definição da tipologia dos tipos de empresários agrícolas envolvidos na cultura da nogueira/noz.

description: In this work, we combine phosphorous-implanted emitters with rear surface passivation for the industrial
realisation of highly efficient p-type silicon solar cells. The post-implantation anneal, that typically is used for dopant
activation and annealing the crystal damage formed during ion implantation, also serves for growing a high-quality
thermal oxide rear surface passivation layer at no additional cost. The combination of ion-implantation and thermal
oxidation thus reduces the number of required process steps for the fabrication of large area PERC type cells. The
implantation inherent elimination of phosphosilicate glass removal and edge isolation steps further streamline the process
sequence. On conventional Cz wafers of 156 mm size, we achieve peak efficiencies of 19.2 % for PERC devices,
outperforming parallel processed Al-BSF solar cells by 0.3 % absolute. In addition, the absence or presence of a wet
chemical cleaning step before thermal oxidation shows no impact on cell efficiency. The application of the presented
process flow on high-quality magnetic Cz-Si wafers allows for remarkable conversion efficiencies up to 19.7 %.

description: The bypass diode is the most critical quality- and lifetime relevant component in a photovoltaic
junction box. It is meant to safeguard the module from hot spots and their secondary damages in case of temporary
and returning shading. By this, it is possible to grant a power reduced but ongoing operation of the affected module
and the corresponding string. Actual reports of insurers point out an increasing number of system defects in pvsystems
caused by bypass diodes due to over temperature.
The bypass diode is critically regarded in this paper by comparing the normative recommendations of the DIN EN
50548:2012-02 “Junction boxes for photovoltaic modules” and the SN 29500-3 “Expected values for discrete
semiconductors”. The results are verified by the company owned and certified testing laboratory under normative and
expanded conditions.

description: BACKGROUND: Efficient trial designs are required to prioritise promising drugs within Phase II trials. Adaptive designs are examples of such designs, but their efficiency is reduced if there is a delay in assessing patient responses to treatment. METHODS: Motivated by the WIRE trial in renal cell carcinoma (NCT03741426), we compare three trial approaches to testing multiple treatment arms: (1) single-arm trials in sequence with interim analyses; (2) a parallel multi-arm multi-stage trial and (3) the design used in WIRE, which we call the Multi-Arm Sequential Trial with Efficient Recruitment (MASTER) design. The MASTER design recruits patients to one arm at a time, pausing recruitment to an arm when it has recruited the required number for an interim analysis. We conduct a simulation study to compare how long the three different trial designs take to evaluate a number of new treatment arms. RESULTS: The parallel multi-arm multi-stage and the MASTER design are much more efficient than separate trials. The MASTER design provides extra efficiency when there is endpoint delay, or recruitment is very quick. CONCLUSIONS: We recommend the MASTER design as an efficient way of testing multiple promising cancer treatments in non-comparative Phase II trials.

description: We demonstrate the interaction-induced blockade effect in an ultracold $^{88}$Sr gas via studying the time dynamics of a two-photon excitation to the triplet Rydberg series $5\mathrm{s}n\mathrm{s}\, ^3\textrm{S}_1$ for five different principle quantum numbers $n$ ranging from 19 to 37. By using a multi-pulse excitation sequence to increase the detection sensitivity we could identify Rydberg-excitation-induced atom losses as low as $<1\%$. Based on an optical Bloch equation formalism, treating the Rydberg-Rydberg interaction on a mean-field level, the van der Waals coefficients are extracted from the observed dynamics, which agree fairly well with \emph{ab initio} calculations.

description: The installation of PV elements on buildings has increased significantly in the last years. However,
how these Building Integrated Photovoltaic (BiPV) elements interact with building and how the building integration
(orientation, inclination, insulation) influences the operative condition is still not clear. An important parameter that
has to be taken into consideration when a PV module is used as building element, is its working temperature.
Different technologies, different integration solutions and different inclinations may have an impact on the working
temperatures of a BiPV and consequently on the performance of the module. This paper presents how the
performance of different crystalline and amorphous silicon modules is influenced by the temperatures reached during
operation when they are fully integrated or ventilated and inclined at 30° or 90°.The investigation confirms that the
crystalline modules have a lower performance during summer season when the working temperatures of the modules
are high. On the other hand, the amorphous silicon modules exhibit a better performance when ambient temperatures
are high and consequently also the working temperatures of the modules. In general, the amorphous silicon modules
tend to show a better performance when they are inclined at 30°, whereas for the crystalline modules, inclination does
not appear to be a very significant parameter. Integration has been proven to favor the performance of amorphous
silicon modules and not so much the crystalline modules.

The aim of this paper is to review the issue of the significance of these detections and, in particular, take account of publication bias. A literature search revealed 38 reported detections of narrow, strongly shifted (v/c >= 0.05) X-ray lines in the 1.5-20 keV spectra of Seyfert galaxies and quasars. These published data show a close, linear relationship between the estimated line strength and its uncertainty, in the sense that better observations (with smaller uncertainties) only ever show the smallest lines. This result is consistent with many of the reported lines being false detections resulting from random fluctuations, drawn from a large body of data and filtered by publication bias such that only the most `significant' fluctuations are ever reported. The reality of many of these features, and certainly their prevalence in the population at large, therefore remains an open question that is best settled though uniform analysis (and reporting) of higher quality observations.

description: A revisão visa avaliar uma técnica para solucionar a formação de arcos coesivos em silos verticais responsáveis pela obstrução do fluxo do material armazenado nos silos no processo de descarga, demonstrando que a utilização de ventilação de pneumático lateral é eficiente para a desobstrução de fluxo. A metodologia propõe-se a construção de um modelo reduzido de um silo, em função da viabilidade econômica do projeto e da funcionalidade, e para a determinação das propriedades de fluxo do material armazenado será utilizada a metodologia proposta por Milani (1993) em que é feito o ensaio de cisalhamento direto. Parte-se de um percurso pela literatura referente a uma perspectiva histórica dos silos e contribuição sobre o fluxo dos produtos armazenados em silos em Jenike & Johanson (1868), sobre as propriedades físicas de produtos armazenados em Calil Junior (2007), contribuição sobre a tremonha como parte influente para o estudo do escoamento do produto ensilado com Neto (2009) e Rotter (1998), tempo de armazenagem do produto como fator que favorece a formação de arcos coesivos em Batista (2009), algumas diretrizes sobre o uso de modelos reduzidos em pesquisas por Garnier (1998), a possibilidade de um modelo com automação segundo Holanda (1975), e o uso de sensores de nível em silos por Cassiolato (2005). A maioria dos silos existentes no mundo não apresenta condições ideais de operação, seus projetos ainda são complexos e, muitas vezes, rodeados de incertezas. Dessa forma, este projeto pretende avaliar a formação de arcos coesivos como uma variável responsável pelo processo de obstrução nos silos, e propor uma alternativa para solucionar esse problema.

description: OM&T | Moser Baer Technologies has developed a process for high efficient crystalline solar cells
with the use of thin film amorphous silicon passivation, which is normally referred to as a heterojunction solar cell.
By optimizing the wet-chemical surface treatment, a-Si intrinsic passivation, a-Si doping layers and the deposition of
contact layers we have been able to demonstrate a 19.9% and 19.1% aperture area efficiency, for respectively a 1 cm²
and 25cm² cell. The samples have been made by using aluminium doped zinc oxide as front TCO layer in
combination with an optimized metal grid to compensate for the higher sheet resistance. This platform of the high
efficient c-Si solar cell has enabled us to test different light-trapping designs both on the wafer and on the external
cover glass. We have demonstrated a JSC gain of 3% by use of a textured retro-reflective cover glass instead of a flat
reference. The external light trapping features allow for a more smoothened surface texturing of the c-Si cell resulting
in higher VOC values and thus higher efficiencies.

description: BACKGROUND: Tobacco consumption is one of the leading causes of preventable death. In this study, we analyze whether someone's genetic predisposition to smoking moderates the response to tobacco excise taxes. METHODS: We interact polygenic scores for smoking behavior with state-level tobacco excise taxes in longitudinal data (1992-2016) from the US Health and Retirement Study (N = 12,058). RESULTS: Someone's genetic propensity to smoking moderates the effect of tobacco excise taxes on smoking behavior along the extensive margin (smoking vs. not smoking) and the intensive margin (the amount of tobacco consumed). In our analysis sample, we do not find a significant gene-environment interaction effect on smoking cessation. CONCLUSIONS: When tobacco excise taxes are relatively high, those with a high genetic predisposition to smoking are less likely (i) to smoke, and (ii) to smoke heavily. While tobacco excise taxes have been effective in reducing smoking, the gene-environment interaction effects we observe in our sample suggest that policy makers could benefit from taking into account the moderating role of genes in the design of future tobacco control policies.

description: contacfoil® is a flexible, laminated foil system, which can be produced in a roll-to-roll-process and
which enables the monolithic assembly of modules using back contact PV-cells. The foil system is comprised of a
laser patterned conductor layer and an insulation layer (PVB) with laser produced openings to accommodate the cells
contacts. It is combined with embedding layers to form the inside of a PV-module to protect and interconnect the
cells. In this paper we report on results obtained with reliability tests, namely temperature cycles under load and
damp heat exposure according to IEC61215. These tests have been performed with various material combinations
and using different technologies for cell contacting. The results show that contacfoil® is a fully functional alternative
to flexible circuit boards or string based interconnection methods for back-contact cells offering advantages in
module assembly and costs. The foil system can accommodate various module designs as it can be combined with a
range of embedding materials and can be used with low temperature solders, conductive epoxies or hybrids alike. The
conductor materials and thicknesses (resistance) can be adapted to the specified power rating of the module.

description: We propose statistical systems based on $p$-adic numbers. In the systems, the Hamiltonian is a standard real number which is given by a map from the $p$-adic numbers. Therefore we can introduce the temperature as a real number and calculate the thermodynamical quantities like free energy, thermodynamical energy, entropy, specific heat, etc. Although we consider a very simple system, which corresponds to a free particle moving in one dimensional space, we find that there appear the behaviors like phase transition in the system. Usually in order that a phase transition occurs, we need a system with an infinite number of degrees of freedom but in the system where the dynamical variable is given by $p$-adic number, even if the degree of the freedom is unity, there might occur the phase transition.

description: Within the framework of the Color Glass Condensate model, we evaluate quark and gluon Generalized Parton Distributions (GPDs) and the cross section of Deeply Virtual Compton Scattering (DVCS) in the small-$x_{B}$ region. We demonstrate that the DVCS cross section becomes independent of energy in the limit of very small $x_{B}$, which clearly indicates saturation of the DVCS cross section. Our predictions for the GPDs and the DVCS cross section at high-energies can be tested at the future Electron-Ion Collider and in ultra-peripheral nucleus-nucleus collisions at the LHC.

Sharp Magnetic Field Dependence of the 2D Hall Coefficient Induced by Classical Memory Effects

description: We show that a sharp dependence of the Hall coefficient $R$ on the magnetic field $B$ arises in two-dimensional electron systems with randomly located strong scatterers. The phenomenon is due to classical memory effects. We calculate analytically the dependence $R(B)$ for the case of scattering by hard disks of radius $a$, randomly distributed with concentration $n_0\ll1/a^2$. We demonstrate that in very weak magnetic fields ($ω_cτ\lesssim n_0a^2$) memory effects lead to a considerable renormalization of the Boltzmann value of the Hall coefficient: $δR / R \sim 1 .$ With increasing magnetic field, the relative correction to $R$ decreases, then changes sign, and saturates at the value $δR / R \sim -n_0a^2 .$ We also discuss the effect of the smooth disorder on the dependence of $R$ on $B$.

description: We address the problem of studying the decay of the inflaton field $ϕ$ to another scalar field $χ$ through parametric resonance in the case of a coupling that involves several decay modes. This amounts to the presence of extra harmonic terms in the perturbation of the $χ$ field dynamics. For the case of two frequencies we compute the geometry of the resonance regions, which is significantly altered due to the presence of non-cuspidal resonance regions associated to higher harmonics and to the emergence of instability `pockets'. We discuss the effect of this change in the efficiency of the energy transfer process for the simplest case of a coupling given by a combination of the two interaction terms of homogeneous degree usually considered in the literature. We find that the presence of higher harmonics has limited cosmological implications.

description: The low-lying eigenvalue spectrum of the QCD Dirac operator in the epsilon-regime is expected to match with that of chiral Random Matrix Theory (ChRMT). We study this correspondence for the case including sea quarks by performing two-flavor QCD simulations on the lattice. Using the overlap fermion formulation, which preserves exact chiral symmetry at finite lattice spacings, we push the sea quark mass down to \sim 3 MeV on a 16^3\times 32 lattice at a lattice spacing a \simeq 0.11 fm. We compare the low-lying eigenvalue distributions and find a good agreement with the analytical predictions of ChRMT. By matching the lowest-lying eigenvalue we extract the chiral condensate, Σ(2 GeV)[MSbar] = [251(7)(11) MeV]^3, where errors represent statistical and higher order effects in the epsilon expansion. We also calculate the eigenvalue distributions on the lattices with heavier sea quarks at two lattice spacings. Although the epsilon expansion is not applied for those sea quarks, we find a reasonable agreement of the Dirac operator spectrum with ChRMT. The value of Sigma, after extrapolating to the chiral limit, is consistent with the estimate in the epsilon-regime.

Silicon Solar Cell Characterization and Modelling

description: 27th European Photovoltaic Solar Energy Conference and Exhibition; 1373-1375
description: This study described the degradation by variance of surface and quantum efficiency (QE) in multicrystalline silicon solar cell (mc-Si solar cell) after vibration test which was simulated under the condition of land & air transportation. The vibration test follows some procedures from an unleashed draft of one developing
international Standard. Mechanical defects on the surface of solar cell were obviously inspected by recognizable
patterns evolving, shown from the method of electroluminescence (EL) imaging. The patterns were classified into 7
types by symptoms of crack/micro-crack. On the other hand, quantum efficiency variances of cell were measured in
incident photon-to-electron conversion efficiency (IPCE), i.e. IPCE performance worst-case drop was found indeed
in spectrum as 23.7%. After vibration test, total breakage rate is near 1% and some specific cells had 3% power loss.
EL images showed the sufficient evidences of defect’s growth due to mc-Si cells experienced vibration response
during transshipment simulation. Furthermore, this applied research provided a common vibration test from a prenormative
Standard, and two nondestructive test method, EL and QE/IPCE to evaluate the damaged spot on mc-Si
solar cells. Result shall also be considered as one key point to improve transportation package as well in the future.

description: An optimum adjustment of printing medium and machine parameters is essential to establish
dispensing as an alternative front side metallization process for silicon solar cells. In previous studies [1-3], paste
rheology was found to have a major impact on resulting finger geometry and process stability. In order to find a good
balance between printability and resulting contact geometry, different dispensing pastes were evaluated and
dispensed on Cz–Si 156x156 mm² precursor material equipped with standard aluminium printed back surfaces and
pre-printed front side busbars. In order to determine the optimum co-firing temperature, three completely screenprinted
cell groups were processed in parallel serving as reference cells. Cell results were investigated concerning
finger geometry and electrical parameters. With increasing paste elasticity, the finger width could be reduced down to
43 μm. Furthermore, contact width indicating possible paste spreading on the wafer surface as well as finger necking
turned out to be a crucial geometrical parameter of dispensed contact fingers. Once more, the enormous potential of
dispensing as a front side metallization technique could be demonstrated.
