description: In this paper we obtain a bound $Λ_{\rm NC} < 150$ TeV on the scale of space-time noncommutativity considering photon-neutrino interactions. We compute "star-dipole moments" and "star-charge radii" originating from space-time noncommutativity and compare them with the dipole moments calculated in the neutrino-mass extended standard model (SM). The computation depends on the nature of the neutrinos, Dirac versus Majorana, their mass and the energy scale. We focus on Majorana neutrinos. The "star-charge radius" is found to be $r^* = \sqrt{|< r^2_ν>_{\rm NC}|} =|3\sum_{i=1}^3 (θ^{0i})^2|^{1/4} < 1.6 \times 10^{-19}$ cm at $Λ_{\rm NC} = 150$ TeV.

description: In this article we study the structure and stability of compact astrophysical objects which are ruled by the dark energy equation of state (EoS). The existence of dark energy is important for explaining the current accelerated expansion of the universe. Exact solutions to Einstein field equations (EFE) have been found by considering particularized metric potential, Finch and Skea ansatz \cite{Finch}. The obtained solutions are relevant to the explanation of compact fluid sphere. Further, we have observed at the junction interface, the interior solution is matched with the Schwarzschild's exterior vacuum solution. Based on that, we have noticed the obtained solutions are well in agreement with the observed maximum mass bound of $\approx$ 2$M_{\bigodot}$, namely, PSR J1416-2230, Vela X-1, 4U 1608-52, Her X-1 and PSR J1903+327, whose predictable masses and radii are not compatible with the standard neutron star models. Also, the stability of the stellar configuration has been discussed briefly, by considering the energy conditions, surface redshift, compactness, mass-radius relation in terms of the state parameter ($ω$). Finally, we demonstrate that the features so obtained are physically acceptable and consistent with the observed/reported data \citep{Gondek-Rosinska,Glendenning}. Thus, the present dark energy equation of state appears talented regarding the presence of several exotic astrophysical matters.

Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: From the observations reported to VSNET, we detected short fading episodes in two dwarf novae, RX And (orbital period 5.0 hr) and SU UMa (orbital period 1.8 hr). The episodes in RX And can be naturally explained as the response to a short-term reduction of the mass-transfer rate. A qualitative comparison with VY Scl-type fadings is also discussed. In SU UMa, the same explanation is expected to be more difficult to apply. The viable, but still poorly understood, possibilities include the temporary reduction of quiescent disk viscosity and the temporary reduction of mass-transfer rate. If the latter possibility is confirmed, we probably need a different mechanism from that of VY Scl-type stars.

Publisher: name: ETH Zurich
Year: 2019

description: With the advent of self-driving cars, Autonomous Mobility on Demand (AMoD) may become a very popular mode of transport in the near future because of its low price, convenience and other benefits. This study will explore the congestion effect of introducing a large fleet of autonomous vehicles to cities on a realistic simulation environment and will develop congestion-aware operation strategies for the fleet decision-making process. Refuting some previous results, our results show that replacing private car trips with AMoD rides can improve the overall traffic condition if a good operating strategy is used. Furthermore, our results also indicate that traffic can still be improved when only a fraction of the private car trips are replaced by AMoD rides. The higher the replacement rate is, the better the overall traffic will be. The study concludes with the identification of multiple future research directions that may bring us one step closer to the mobility of future.

 Distribution: United States: FL, LA, MD, NC, SC, VA.
 Comments: Froeschner (1988) listed this species under the combination Edessa florida. Santos et al. (2015) transferred this species from Edessa to Ascra and placed it as a junior synonym of Ascra bifida. North American specimens of the two taxa are relatively easy to separate, and it is difficult to imagine that they are conspecific. Apparently, in the southern part of their range (Mexico, Central America) there are intermediates, and the separation of the two species is more difficult. We have chosen to list both species until further studies can be conducted.

description: We study a model of wealth dynamics [Bouchaud and Mézard 2000, \emph{Physica A} \textbf{282}, 536] which mimics transactions among economic agents. The outcomes of the model are shown to depend strongly on the topological properties of the underlying transaction network. The extreme cases of a fully connected and a fully disconnected network yield power-law and log-normal forms of the wealth distribution respectively. We perform numerical simulations in order to test the model on more complex network topologies. We show that the mixed form of most empirical distributions (displaying a non-smooth transition from a log-normal to a power-law form) can be traced back to a heterogeneous topology with varying link density, which on the other hand is a recently observed property of real networks.

description: Na década de 90, com o aumento do preço da soja no mercado internacional e a ocupação de áreas produtoras tradicionais, outras glebas nos Cerrados foram intensivamente incorporadas para a produção de soja, com destaque para Luís Eduardo Magalhães – BA, Balsas – MA e Pedro Afonso – TO. Essa expansão pode significar a ampliação de impactos ambientais nos solos, nos recursos hídricos, na biodiversidade e nas condições de equilíbrio ecológico dos Cerrados. O estudo valora economicamente, através do Método Custo-Reposição (MCR), os impactos ambientais de tecnologias de plantio de soja em região de expansão recente nos Cerrados, tendo como estudo de caso o município de Pedro Afonso - TO. Na região específica do estudo os custos ambientais anuais da produção da soja foram estimados em R$ 82.726,84. Porém, a adoção progressiva de mais produtores ao plantio direto pode reduzir este valor para R$ 22.476,17 ao ano.

description: A complexidade das transformações geradas neste início de século aponta para a tomada de ações inovadoras e para a necessidade de novas habilidades e competências para os gestores nos diversos setores da economia. Por isso, o cooperativismo pode ser visto como um exemplo, se não para solucionar, pelo menos amenizar problemas do setor produtivo agropecuário, dando mais segurança e tranqüilidade aos produtores. Assim sendo, o sucesso do cooperativismo demanda profissionais competentes e capacitados para se estabelecer como uma alternativa de desenvolvimento sócio-econômico. Portanto, este estudo visa identificar as habilidades e competências dos administradores de cooperativas e compará-las às habilidades dos administradores apontadas por uma pesquisa realizada pelo Conselho Federal de Administração – CFA, que teve como público alvo administradores de empresas do setor industrial, comercial e de serviços. Para tanto, foi realizada uma pesquisa, através da aplicação de um questionário e entrevistas informais, junto às pessoas que possuem poder de decisão dentro da Cooperativa Mista dos Produtores Rurais do Sudoeste Goiano Ltda – COMIGO. O que permitiu identificar o perfil dos mesmos, descrever as suas principais habilidades e competências e depois realizar a comparação citada através do uso do Teste Qui-quadrado. Como resultado, observou-se que relacionamento pessoal, capacidade de assumir risco, motivação pessoal, capacidade de negociação, honestidade, tomada de decisão e responsabilidade foram as habilidades que apresentaram os maiores escores no teste Qui-quadrado, mostrando que estas variáveis são mais importantes para os administradores da COMIGO, do que para os administradores de empresas comerciais e industriais pesquisados pelo CFA. Em suma, pode-se afirmar que o administrador competente deve ter capacidade de assumir riscos, mesmo atuando em uma cooperativa. Assim sendo, a motivação pessoal e profissional para superar estes riscos e a habilidade de negociação também devem estar presentes na bagagem dos administradores eficazes.

description: Quantum key distribution (QKD offers a long-term solution to establish information-theoretically secure keys between two distant users. In practice, with a careful characterization of quantum sources and the decoy-state method, measure-device-independent quantum key distribution (MDI-QKD) provides secure key distribution. While short-distance fibre-based QKD has already been available for real-life implementation, the bottleneck of practical QKD lies on the limited transmission distance. Due to photon losses in transmission, it was believed that the key generation rate is bounded by a linear function of the channel transmittance, $O(η)$, without a quantum repeater, which puts an upper bound on the maximal secure transmission distance. Interestingly, a new phase-encoding MDI-QKD scheme, named twin-field QKD, has been suggested to beat the linear bound, while another variant, named phase-matching quantum key distribution (PM-QKD), has been proven to have a quadratic key-rate improvement, $O(\sqrtη)$. In reality, however, the intrinsic optical mode mismatch of independent lasers, accompanied by phase fluctuation and drift, impedes the successful experimental implementation of the new schemes. Here, we solve this problem with the assistance of the laser injection technique and the phase post-compensation method. In the experiment, the key rate surpasses the linear key-rate bound via 302 km and 402 km commercial-fibre channels, achieving a key rate over 4 orders of magnitude higher than the existing results in literature. Furthermore, with a 502 km ultralow-loss fibre, our system yields a secret key rate of 0.118 bps. We expect this new type of QKD schemes to become a new standard for future QKD.

description: A graph $Γ$ is $G$-symmetric if $G$ is a group of automorphisms of $Γ$ which is transitive on the set of ordered pairs of adjacent vertices of $Γ$. If $V(Γ)$ admits a nontrivial $G$-invariant partition ${\cal B}$ such that for blocks $B, C \in {\cal B}$ adjacent in the quotient graph $Γ_{\cal B}$ of $Γ$ relative to ${\cal B}$, exactly one vertex of $B$ has no neighbour in $C$, then $Γ$ is called an almost multicover of $Γ_{\cal B}$. In this case an incidence structure with point set ${\cal B}$ arises naturally, and it is a $(G, 2)$-point-transitive and $G$-block-transitive 2-design if in addition $Γ_{\cal B}$ is a complete graph. In this paper we classify all $G$-symmetric graphs $Γ$ such that (i) ${\cal B}$ has block size $|B| \ge 3$; (ii) $Γ_{\cal B}$ is complete and almost multi-covered by $Γ$; (iii) the incidence structure involved is a linear space; and (iv) $G$ contains a regular normal subgroup which is elementary abelian. This classification together with earlier results in [A. Gardiner and C. E. Praeger, Australas. J. Combin. 71 (2018) 403--426], [M.~Giulietti et al., J. Algebraic Combin. 38 (2013) 745--765] and [T. Fang et al., Electronic J. Combin. 23 (2) (2016) P2.27] completes the classification of symmetric graphs satisfying (i) and (ii).

description: A região do Alto Tietê caracteriza-se por uma das mais produtivas regiões agrícolas do país, concentrando sua produção nas cadeias das hortaliças folhosas, cogumelos comestíveis, caqui, nêspera e flores. Com uma concentração de aproximadamente 80% de pequenos produtores rurais com áreas de até 20 hectares, exige dos atores locais um elevado grau de sinergia para que possam efetivamente implantar seus recursos financeiros, econômicos, produtos e serviços em prol do desenvolvimento territorial. O estudo aborda a importância do esforço coletivo do SEBRAE/SP, Sindicato Rural de Mogi das Cruzes e CATI/EDR Mogi das Cruzes, que implantaram um programa conjunto para atuarem no setor agrícola a partir de 1997. Mostra, também, que a partir do ano de 2001, por meio do Programa SAI, convênio realizado entre estes parceiros, o acesso do produtor rural a capacitação é ampliado, refletindo numa mudança da rede de atores locais, com a organização de novos grupos de produtores. Observou-se, também, a importância de disponibilizar um conjunto de meios para o produtor se capacitar, não só através de cursos, mas também, no intercâmbio com outros elos da cadeia.

description: O comércio internacional tem adquirido crescente importância para a economia brasileira, em particular para o agronegócio. Dentro do agronegócio, a produção e a exportação de carne bovina são destaques. Deste modo, o entendimento de políticas públicas de outros países que afetem o comércio internacional e o impacto das mesmas em nosso país é de grande importância. A União Européia é um dos principais parceiros comerciais do Brasil e é conhecida pela profunda interferência que impõe ao seu setor agropecuário. Tal fato tem impacto em outros países, inclusive o Brasil, que tem despontado como competidor no mercado internacional de produtos que a UE subsidia. A expansão da União Européia em 2004 e a reforma de sua Política Agrícola Comum têm sido estudadas em diferentes regiões do mundo. Utilizando o modelo de equilíbrio geral GTAP, este trabalho pretende analisar o impacto da expansão da União Européia no agronegócio da carne bovina brasileiro. Os resultados mostram que as diferentes políticas da UE impactam o setor, diminuindo suas exportações. ------------------------------------------------- International trade has acquired increasing importance for the Brazilian economy, especially for agribusiness. Beef production and exports are especially important within Brazilian agribusiness. In this way, understanding other countries policies that affects international trade and its impacts in our country is important. The European Union is one of the most important Brazilian trade partners and it is known by its strong interference on its agricultural sector. This fact has an important impact on other countries, including Brazil. The recent European enlargement and its Common Agricultural Policy Reform has been studied at different regions of the World. This research project aims to assess the impacts of European Union Enlargement on the Brazilian beef sector using GTAP, a general equilibrium model. It was found that the different EU agricultural policies affect the sector, diminishing its exports.

description: We study the motility-induced aggregation of active Brownian particles (ABPs) on a porous, circular wall. We observe that the morphology of aggregated dense-phase on a static wall depends on the wall porosity, particle motility, and the radius of the circular wall. Our analysis reveals two morphologically distinct, dense aggregates; a connected dense cluster that spreads uniformly on the circular wall and a localized cluster that breaks the rotational symmetry of the system. These distinct morphological states are similar to the macroscopic structures observed in aggregates on planar, porous walls. We systematically analyze the parameter regimes where the different morphological states are observed. We further extend our analysis to motile circular rings. We show that the motile ring propels almost ballistically due to the force applied by the active particles when they form a localized cluster, whereas it moves diffusively when the active particles form a continuous cluster. This property demonstrates the possibility of extracting useful work from a system of ABPs, even without artificially breaking the rotational symmetry.

Dynamics of Evapotranspiration Partitioning with Concurrent Subcanopy Flux Measurements in a Montane Sierra Nevada Forest
Creators: name: Wolf, Sebastian

Publisher: name: ETH Zurich
Year: 2019

description: The component fluxes of Evapotranspiration (ET) cannot be directly measured at the ecosystem scale, and standardized approaches to partition the components fluxes of eddy-covariance (EC) measured ET are currently not available. Concurrent measurements of below and above canopy EC in forests provide a promising approach. However, our understanding of the performance of such measurements is still very limited as questions remain regarding the spatial variability, canopy (de-)coupling, and the temporal dynamics of subcanopy EC measurements. To address these challenges, we measured and partitioned ET with two subcanopy and concurrent above canopy
EC towers in a montane forest at Sagehen Creek (California), having a pronounced Mediterranean climate. We analysed these paired measurements for 15 months and will present the spatial and temporal dynamics of this flux partitioning approach. Based on these results, we will discuss the relevant process controls, methodological limitations and implications for a wider application of such concurrent measurements.

description: The thesis investigates the impact of a Guanidinium iodide (GAI) surface treatment on the structural and photophysical properties of triple-cation CsMAFA perovskite films. The results suggest that a low-concentration treatment with GAI enhances the CsMAFA perovskite crystallinity, homogenizes the PL intensity, and improves the device performance. While, on the other hand, excess GAI yields low degree of crystallization leading to poor device performance. The results show that controlling the concentration of surface treatment agents is important for the homogenization of perovskite optoelectronic properties and hence eliminating performance losses and instabilities.

description: Στις μέρες μας δεν θα έπρεπε να είμαστε εφησυχασμένοι με ένα από τα πλέον ανησυχητικά γεγονότα, αυτό της εξάντλησης των φυσικών πόρων της υφηλίου. Αυτή η εξάντληση είναι απόρροια του γραμμικού μοντέλου παραγωγής το οποίο απορρίπτει τα προϊόντα όταν ολοκληρώνουν τον κύκλο της ζωής τους. Η ελαχιστοποίηση του ανθρώπινου περιβαλλοντικού αποτυπώματος μέσω της ελαχιστοποίησης των αποβλήτων, η καλύτερη χρήση πρώτων υλών, η ενεργειακή αναβάθμιση και λελογισμένη χρήση των φυσικών πόρων, ανήκουν στις κυριότερες λύσεις που έχουμε αυτή τη στιγμή στα χέρια μας για την αποτροπή της καταστροφής. Όλα αυτά επιτυγχάνονται με την μετάβαση της οικονομίας μας, άρα και των επιχειρήσεων μας σε ένα κυκλικό μοντέλο οικονομίας το οποίο αποτελεί εχέγγυο βιώσιμης ανάπτυξης. Η Ευρωπαϊκή Ένωση (ΕΕ) πρωτοστάτησε θέτοντας σαφείς περιβαλλοντικούς και κλιματικούς στόχους ενώ παράλληλα ενθάρρυνε τις επιχειρήσεις τόσο σε τοπικό όσο και σε περιφερειακό επίπεδο. Μέσα από ένα πιο βιώσιμο μοντέλο παραγωγής, με οικολογικό σχεδιασμό – διαχείριση αποβλήτων κα., είναι δεδομένο ότι οι εταιρείες θα δουν αύξηση του κύκλου εργασιών τους, δραστική μείωση των δαπανών τους και δημιουργία θέσεων εργασίας. Μέχρι το έτος 2030 η Ευρωπαϊκή Ένωση (ΕΕ) θέλει να μειώσει τα αέρια του θερμοκηπίου κατά 2-4%, να μειώσει τις εισροές υλικών κατά 17-24%, να ενισχύσει το ΑΕΠ της ΕΕ έως 4%, και να εξοικονομήσει 630 δισεκατομμύρια ευρώ ετησίως στις ευρωπαϊκές βιομηχανίες. Μέσα από ένα ειδικώς δομημένο ερωτηματολόγιο η παρούσα έρευνα θέλει να εξετάσει την προσαρμογή τέτοιων πρακτικών, κυκλικής οικονομίας, σε ένα οικοσύστημα που πρόσφατα χαρτογραφήθηκε στον ελλαδικό χώρο, αυτό των νεοφυών επιχειρήσεων. Ο λόγος για τον οποίο επιλέχθηκαν οι ελληνικές νεοφυείς επιχειρήσεις ήταν οι μεγάλες δυναμικές ανάπτυξης που έχουν, επειδή είναι συνυφασμένες με την ενσωμάτωση καινοτόμων τεχνολογιών και επειδή επιδιώκουν να δημιουργήσουν νέες αγορές ή να εξελίξουν δυναμικά υπάρχουσες.

 Comments: Early records of this species from British Columbia, California, Oregon, and Utah are misidentifications of Neottiglossa tumidifrons; the records from Arizona (Torre-Bueno 1939 b, Thomas & Werner 1981) are probably also misidentifications, but are probably not Neottiglossa tumidifrons. Froeschner (1988) also listed Neottiglossa coronaciliata Ruckes as a separate species; it was placed as a synonym of Neottiglossa cavifrons (Rider, 1990).

description: We consider the scalar operators corresponding to semiclassical string states in AdS_5xS^5 with the three angular momenta in S^5 non-trivial. The string states recieve quantum corrections and we study the corresponding process on the gauge theory side. The anomalous dimension of the scalar operators is computed using the Bethe ansatz and we find the correction that corresponds to the energy of the quantized string. We restrict for simplicity to the case where two of the angular momenta in S^5 are equal.

description: Plants have an important effect on our climate: by assimilating CO2 through photosynthesis, plants mitigate increases in atmospheric CO2 concentrations, transfer water to the atmosphere and reduce surface temperatures. As atmospheric CO2 concentration increases, plants can reduce the opening of their stomata and still enhance photosynthesis. This CO2 fertilization effect can lead to increased growth but also to reduced transpiration rates, thereby contributing to warmer surface temperatures. There is ongoing debate on how these contrasting effects will influence our climate, in particular the contribution of forest ecosystems. It is however difficult to measure transpiration to understand these changes. Direct eddy covariance (EC) measurements are currently the best available approach to directly observe interactions linked to biosphere-atmosphere CO2 and water vapor exchange. While there are well-established methods to partition CO2 fluxes into the component fluxes of photosynthesis and respiration, there is still no standardized method to partition water vapor fluxes (evapotranspiration) into the component fluxes of evaporation and transpiration. In this study, we are using two years of concurrent below and above canopy EC measurements in a mixed deciduous forest in Switzerland to partition water vapor fluxes into the biological transpiration and physical evaporation. We compare our results with evaporation modeled with the Haghighi & Or (HO) model, and transpiration obtained from two models, namely the ecosystem demographic (ED2) and the Haghighi & Kirchner (HK) transpiration models, as well as derived from plot-level sap flow measurements. We found that transpiration accounted on average for 80% of evapotranspiration, emphasizing a considerably lower contribution from evaporation. Mid-afternoon reductions in transpiration were found during periods of high vapor pressure deficit in summer. Despite pronounced differences in environmental conditions during the observed years, evapotranspiration and its transpiration component had a low inter-annual variability in this mixed forest. These results suggest a reliable access of the trees to water resources and stomatal regulation in response to enhanced atmospheric evaporative demand. Our results show the potential of concurrent below and above canopy EC measurements to partition evapotranspiration in forested areas.

description: Εισαγωγή: Τα τελευταία χρόνια έχει ενταθεί η έρευνα επάνω στην εντερική μικροχλωρίδα και τα οφέλη για την υγεία από ένα υγιές μικροβίωμα. Τα φλαβονοειδή αποτελούν μια ο-μάδα πολυφαινολών ωφέλιμων για την υγεία κυρίως λόγω της αντιοξειδωτικής δράσης τους. Η αλληλεπίδραση αυτών των δύο και τα πιθανά οφέλη για τον οργανισμό από αυτό αποτελούν σημείο έντονου επιστημονικού ενδιαφέροντος. Σκοπός: Η διερεύνηση της αλληλεπίδρασης εντερικού μικροβιώματος – φλαβονοειδών τόσο σε επίπεδο μεταβολισμού των φλαβονοειδών όσο και του αντίκτυπου της κατανάλω-σης των φλαβονοειδών στο μεταβόλωμα του εντερικού μικροβιόκοσμου. Μέθοδος: Από διατροφική παρέμβαση με βιταμίνη D, Ca, βιοφλαβονοειδή (ναρινγκίνη & εσπεριδίνη) σε γυναίκες στην εμμηνόπαυση με σκοπό τη βελτίωση της οστεοπενίας, εξετά-σθηκαν δείγματα κοπράνων στους 0 και 9 μήνες μετά την παρέμβαση, με τη χρήση φα-σματοσκοπίας NMR και LCMS, για μεταβολές στη συγκέντρωση μεταβολιτών των φλα-βονοειδών και χαρακτηριστικών μεταβολιτών του εντερικού μικροβιώματος. Για την στα-τιστική ανάλυση των αποτελεσμάτων χρησιμοποιήθηκαν πολυμεταβλητές στατιστικές προσεγγίσεις (PLS-DA/PCA) Αποτελέσματα: Παρατηρήθηκε στατιστικά σημαντική διαφοροποίηση σε δύο μεταβολίτες των πολυφαινολών – το διϋδροκαφεϊκό και το υδροκινναμικό οξύ – αν και κατά γενική ομολογία οι ομάδες 0 και 9 μηνών δεν διαφοροποιούνται σε επίπεδο μεταβολιτών των πο-λυφαινολών. Σε επίπεδο εντερικού μεταβολώματος παρατηρήθηκαν σημαντικές διαφορές ανάμεσα στις δύο ομάδες σε 8 μεταβολίτες - ισοβαλερικό οξύ, βαλίνη, ασπαραγγινικό οξύ, μεθανόλη, γλυκερόλη, τυροσίνη, φαινυλοξικό οξύ, φαινυλαλανίνη. Συμπεράσματα: Οι πολυφαινόλες έδειξαν να χρησιμοποιούνται ως υποστρώματα από το εντερικό μικροβίωμα επηρεάζοντας κατ’ επέκταση και το εντερικό μεταβόλωμα.

description: We use angle-resolved photoemission with circularly polarized excitation to demonstrate that in the 5x1 superstructure-free Pb-Bi2212 material there are no signatures of time-reversal symmetry breaking in the sense of the criteria developed earlier (Kaminski et al. Nature {\bf 416}, 610 (2002)). In addition to the existing technique, we suggest and apply an independent experimental approach to prove the absence of the effect in the studied compounds. The dichroic signal retains reflection antisymmetry as a function of temperature and doping and in all mirror planes, precisely defined by the experimental dispersion at low energies. The obtained results demonstrate that the signatures of time-reversal symmetry violation in pristine Bi2212, as determined by ARPES, are not a universal feature of all cuprate superconductors.

Matter vs. vacuum oscillations at long baseline accelerator neutrino experiments

description: The neutrino oscillation probabilities at the long-baseline accelerator neutrino experiments are expected to be modified by matter effects. We search for evidence of such modification in the data of T2K and NO$ν$A, by fitting the data to the hypothesis of (a) matter modified oscillations and (b) vacuum oscillations. We find that vacuum oscillations provide as good a fit to the data as matter modified oscillations. Even extended runs of T2K and NO$ν$A, with 5 years in neutrino mode $(5 ν)$ and five years in anti-neutrino mode $(5 \barν)$, can {\bf not} make a $3~σ$ distinction between vacuum and matter modified oscillations. The proposed experiment DUNE, with neutrino and anti-neutrino runs of 5 years each $(5 ν+ 5 \barν)$, can rule out vacuum oscillations by itself at $5~σ$ if the hierarchy is normal. If the hierarchy is inverted, a $5~σ$ discrimination against vacuum oscillations requires the combination of $(5 ν+ 5 \barν)$ runs of T2K, \nova and DUNE.

description: We consider a gauge-invariant Hamiltonian analysis for Yang-Mills theories in three spatial dimensions. The gauge potentials are parametrized in terms of a matrix variable which facilitates the elimination of the gauge degrees of freedom. We develop an approximate calculation of the volume element on the gauge-invariant configuration space. We also make a rough estimate of the ratio of $0^{++}$ glueball mass and the square root of string tension by comparison with $(2+1)$-dimensional Yang-Mills theory.

description: We report on the dynamical formation of self-bound quantum droplets in attractive mixtures of $^{39}$K atoms. Considering the experimental observations of Semeghini et al., Phys. Rev. Lett. 120, 235301 (2018), we perform numerical simulations to understand the relevant processes involved in the formation of a metastable droplet from an out-of-equilibrium mixture. We first analyze the so-called self-evaporation mechanism, where the droplet dissipates energy by releasing atoms, and then we consider the effects of losses due to three-body recombinations and to the balancing of populations in the mixture. We discuss the importance of these three mechanisms in the observed droplet dynamics and their implications for future experiments.

description: To one loop the effective neutrino photon interaction takes place through the vector-vector type and the axialvector-vector type amplitude. In this work we explicitly write down the form of the axialvector-vector amplitude to all orders in the external magnetic field in a medium. We then infer upon its zero external momentum limit which contributes to the effective charge of the neutrinos inside a magnetized medium. We further show its gauge invariance properties.

description: Power dissipation is a great challenge for the continuous scaling down and performance improvement of CMOS technology, due to thermionic current switching limit of conventional MOSFETs. In this work, we show that this problem can be overcome by using cold metals as the transistor's injection source, which are different from conventional metals and can filter high energy electrons to break the Boltzmann tyranny. It is proved that the subthreshold swing (SS) of thermionic current of transistor using cold metal contact can be extremely smaller than 60 mV/decade at room temperature. Specifically, two-dimensional (2D) transition metal chalcogenide (TMD) cold metals of NbX$_2$ and TaX$_2$(X=S, Se, Te) are proposed as the injection source of FETs. Quantum transport simulations indicate that promising switching efficiency and on-state current can be achieved using TMD cold metal injection source, which is beneficial for energy efficient applications.

description: This study evaluates all USDA cotton supply and demand estimates for the United States and China (including unpublished price forecasts) from 1985/86 through 2009/10 for accuracy and efficiency. Results reveal that at every stage of the forecasting cycle forecast smoothing was the most widespread and persistent type of inefficiency observed in most U.S. variables. Correlation with past errors indicated the tendency to repeat past errors in most cases. Tendency to overestimate growth was also found. Bias was uncommon and limited to several cases of overestimation of China’s exports and U.S. price and underestimation of China’s domestic use. While forecasts of China’s imports and endings stocks improved, U.S. price and ending stock forecast errors became larger toward the end of the study period.
The particle emitter size dependence on energy in $e^+ e^-$ annihilations into hadrons

description: The nearly energy independent hadron emitter dimension $r$, measured in $e^+e^-$ annihilation in the energy range 10 to 91 GeV via the Bose-Einstein correlation of two identical charged pions, is shown to be well accounted for by choosing the hadron jets as independent pion sources. To this end the known normalised factorial cumulant moments dependence on particle sources is adapted to the Bose-Einstein correlation formalism to yield a relation between $r$ and these sources. This approach is also able to account for the measured $r$ values obtained for the $Z^0$ decays into two and three hadron jets. Finally the estimated $r$ value of the hadronic $Υ(9.46)$ decay via three gluons is expected to be higher by about 6 to 11 % over that predicted for its one photon hadronic decay mode.
