description: Modern remote sensing platforms such as unmanned aerial vehicles (UAVs) that can carry a variety of sensors including RGB frame cameras, hyperspectral (HS) line cameras, and LiDAR sensors are commonly used in several application domains. In order to derive accurate products such as point clouds and orthophotos, sensors’ interior and exterior orientation parameters (IOP and EOP) must be established. These parameters are derived/refined in a triangulation framework through minimizing the discrepancy between conjugate features extracted from involved datasets. Existing triangulation approaches are not general enough to deal with varying nature of data from different sensors/platforms acquired in diverse environmental conditions. This research develops a generic triangulation framework that can handle different types of primitives (e.g., point, linear, and/or planar features), and sensing modalities (e.g., RGB cameras, HS cameras, and/or LiDAR sensors) for delivering accurate products under challenging conditions with a primary focus on digital agriculture and stockpile monitoring application domains.

description: Algorithmen und algorithmische Entscheidungssysteme durchdringen immer stärker unsere Welt: „Jeder Einzelne ist Tag für Tag von Entscheidungen betroffen, die Algorithmen für und über uns treffen – meist ohne dass wir es wissen oder bewusst wahrnehmen“ (Grzymek & Puntschuh, 2019, S. 5). Wir bekommen personalisierte Werbung, sehen in Sekundenschnelle den kürzesten Weg von A nach B und werden auf potenzielle Straffälligkeit beurteilt (Grzymek & Puntschuh, 2019). So wurde Robert McDaniel in Folge des predective policing programs, einer automatisierten Analyse von historischen Falldaten, mitgeteilt, dass er zu 99 % Täter oder Opfer einer Schießerei werde (Stroud, 2021). Gleichzeitig bieten Algorithmen große Chancen, indem sie schnell und effizient mit großen Datenmengen umgehen können.

description: Este artículo presenta una experiencia significativa realizada en el Colegio Gente Unida de Medellín, donde se buscó fortalecer la estética del lenguaje en los estudiantes de 6° a 11° y el CLEI formación para adultos. Mediante el uso del diario personal y el fomento de la lectoescritura. A través de una metodología activa y participativa, se promovió la reflexión, la escritura creativa y el análisis crítico, logrando que los estudiantes desarrollaran un uso más consciente y expresivo del lenguaje. Los resultados indican mejoras en la competencia escritural, el pensamiento crítico y el disfrute de la lectura y la escritura. Se concluye que el diario personal es una herramienta pedagógica valiosa para fomentar la creatividad y el desarrollo de habilidades lingüísticas en el aula. Se recomienda la implementación continua de esta práctica con ajustes según las necesidades de los estudiantes.

description: Digital signatures are widely used to provide security for electronic communications, for example in financial transactions and electronic mail. Currently used classical digital signature schemes, however, only offer security relying on unproven computational assumptions. In contrast, quantum digital signatures (QDS) offer information-theoretic security based on laws of quantum mechanics (e.g. Gottesman and Chuang 2001). Here, security against forging relies on the impossibility of perfectly distinguishing between non-orthogonal quantum states. A serious drawback of previous QDS schemes is however that they require long-term quantum memory, making them unfeasible in practice. We present the first realisation of a scheme (Dunjko et al 2013) that does not need quantum memory, and which also uses only standard linear optical components and photodetectors. To achieve this, the recipients measure the distributed quantum signature states using a new type of quantum measurement, quantum state elimination (e.g. Barnett 2009, Bandyopadhyay et al 2013). This significantly advances QDS as a quantum technology with potential for real applications.

Part of the security analysis included in the appendix (supplementary material) for completeness, is similar to the one in our earlier paper arXiv:1309.1375, since it uses similar methods applied to a different setting

description: Mit der doppelten Diskontinuität ist nicht nur der Übergang von der Schule zur Hochschule (1. Diskontinuität) gemeint, welcher vermehrt in Projekten, die sich mit der Bruchstelle zwischen Schulmathematik und universitärer Mathematik beschäftigen, untersucht wird, sondern auch der Übergang von der Hochschule ins Berufsfeld Schule (2. Diskontinuität). Letzterer ist im Vergleich zum ersten jedoch noch wenig erforscht. Hinzu kommt, dass die meisten Studien nicht aus dem deutschsprachigen Raum sind, sich vermehrt auf den Primarstufenbereich beziehen und mit Lehramtsstudierenden durchgeführt wurden. Insbesondere wird selten die Bruchstelle zwischen Fachdidaktik und Praxis beleuchtet. Wie Lehrkräfte bald nach Abschluss ihres Studiums Erkenntnisse aus der fachdidaktischen Forschung in der Praxis umsetzen, bzw. was förderlich oder auch hinderlich (in ihrer Persönlichkeitsentwicklung) ist, um innovative Ansätze in die Praxis zu bringen, ist kaum erforscht: „Teacher education programs provide pre-service teachers with opportunities that are intended to support the development of reform-oriented mathematics teacher identities, but whether that identity manifests when they begin teaching has not been investigated sufficiently in the literature (Losano et al. 2018)“ (Arslan et al., 2022, S. 432f.).
Grundvorstellungen zur Stochastik

description: In den letzten Jahren häuften sich Veröffentlichungen zum Grundvorstellungsbegriff (z. B. Rembowski 2015, Griesel et al. 2019, Salle & Clüver 2021), die aber wenig vernetzt sind. Eine Sichtung verschiedener Begriffsauffassungen zum Bezeichner »Grundvorstellung(en)« (GV) zwingt zu Entscheidungen, wenn man den Begriff anwenden will. Es wird folgende Begriffsklärung vorgeschlagen: „Der Erwerb von GV verändert das individuelle Begriffsbild der Lernenden in Richtung einer Begriffskonvention (Rembowski 2015; hier: definierter Fachbegriff). Dies zeigt sich in ihrem Verständnis, aufgefasst als Kompetenz zur Anwendung in konkreten Situationen - Kommunikation und soziale Interaktion, die auf diesem Begriff beruht, im engeren Sinn Modellieren (Erkennen, Interpretieren/Handeln), sowie Vernetzung mit anderen Begriffen in der mathematischen Theorie. Die Funktion von GV ist ein möglichst gutes Begriffsverständnis abhängig vom lernenden Individuum und der Lehrintention, woraus die Relevanz z. B. von Emotionen und Übersichtlichkeit folgt. GV sind in dem Sinne anschaulich, als sie Musteranwendungen (Anker als mentale Speicher) nutzen, um Mustersituation, Handlungen, graphische Darstellungen und Symbolisches zusammenzuführen sowie vorgestellte Handlungen (Operationen) und Repräsentationswechsel ermöglichen. Sie sind in dem Sinne fundamental, als sie fachlich relevant sind, der Anker so unterrichtet wurde, dass die Lernenden ihn auf viele und relevante neue Situationen übertragen können (Transferabilität), und man didaktisch nicht auf sie verzichten kann, z.B. um typischen Fehlvorstellungen zu begegnen.“ Kurz: Sie sind verständig anwendbar, lernbezogen, anschaulich/ operativ, fundamental (transferabel, fachlich, didaktisch, kommunikativ relevant). Ausführlicheres findet man in den Materialien zum Vortrag unter Fahse (2022).

description: We study a class of three-waveguide axially varying structures whose dynamics are described by the su(3) algebra. Their analytic propagator can be found based on the corresponding Lie group generators. In particular, we show that the field propagator corresponding to three-waveguide structures that have arbitrarily varying coupling coefficients and identical refractive indices is associated with the orbital angular momentum algebra. The conditions necessary to achieve perfect transmission from the first to the last waveguide element are obtained and particular cases are elucidated analytically.

description: We present the experimental realization of transverse mode conversion in an optical fiber via an optically induced long-period grating. The transient gratings are generated by femtosecond laser pulses, exploiting the Kerr effect to translate intensity patterns emerging from multimode interference into a spatial refractive index modulation. Since these modulations exist only while the pump beam is present, they can be used for optical switching of transverse modes. As only a localized part of the grating was written at a time and the probe beam was co-propagating with the pump beam the required pulse energies could be reduced to 120\,nJ which is about a factor of 600 lower than in previous quasi-continuous-wave experiments. Accompanying numerical simulations allow a better understanding of the involved effects and show excellent agreement to the experimental results.

description: In der Zeit der Neuen Mathematik in den 60er und 70er Jahren wurden mathematische Inhalte bereits in der Schule axiomatisch eingeführt, um Lernende auf die mathematische Fachkultur der Hochschule vorzubereiten. Das führte dazu, dass die mathematischen Symbole und Formalismen von den Schüler*innen oftmals als bedeutungslos wahrgenommen wurden (vom Hofe & Blum, 2016). Demgegenüber steht das didaktische Konzept der Grundvorstellungen, mit dem mathematisches Wissen so vermittelt wird, dass es an die kognitiven Fähigkeiten und die persönlichen Erfahrungen der Schüler*innen anknüpft. Auf diese Weise wurden Wege aufgezeigt, mathematisches Grundwissen für den Lernenden erfahrbar zu machen. Das vorliegende Forschungsvorhaben versucht die Frage zu beantworten, welche kognitiven Prozesse aus normativer Sicht bei der Konstruktion von Vorstellungen zur Exponentialfunktion eine Rolle spielen. Mithilfe einer didaktisch orientierte Sachanalyse (Salle & Clüver, 2021) können zwei Grundvorstellungen zur Exponentialfunktion identifiziert werden.

description: We study $p$-spin glass models on regular random graphs. By analyzing the Franz-Parisi potential with a two-body cavity field approximation under the replica symmetric ansatz, we obtain a good approximation of the 1RSB transition temperature for $p=3$. Our calculation method is much easier than the 1RSB cavity method because the result is obtained by solving self-consistent equations with Newton's method.

Dem Trainingsprogramm liegen verschiedene Annahmen zugrunde: (1) Lerntheoretische Grundlagen: Subjektive Theorien (Wahl, 2002), Theorie des situierten Lernens (Stark & Klauer, 2018), Modelllernen (Mietzel, 2007); (2) Unterrichtstheoretische Grundlagen: Sprachspieltheorie mit typischen Sprachmustern (Lüders, 2014); (3) Erkenntnisse aus der Trainingsforschung: Microteaching (Allen & Ryan, 1972). Die Erprobung des Trainingsprogramms fand im Versuchs-Kontrollgruppen-Design statt (n=130). Für die Kontrollgruppe fand ein kognitives Training in Anlehnung an Thiele (1983) statt. Die Evaluation der subjektiven Zufriedenheit mit den Trainingsprogrammen mittels CIEQ (Aleamoni, 1978) ergab eine relativ hohe Zustimmung. Der Nachweis über die Effektivität der Programme mittels einer Videoanalyse von Unterrichtsversuchen der Trainingsteilnehmenden soll in einem nächsten Arbeitsschritt erfolgen (für eine detailliertere Beschreibung des Forschungsprojektes: s.

description: We study high energy particle collisions around the higher dimensional black holes. It is shown that the center of mass energy can be arbitrarily large in the vicinity of the event horizon like the Banados, Silk and West (BSW) process in four dimensions if the following two conditions are satisfied: (i) the horizon is extremal and (ii) the parameters of either of the two colliding particles are fine-tuned, which is called a critical particle condition. We also show that a test particle which satisfies the critical particle condition can reach the event horizon from a distant region for a simple case. Finally, we discuss the relation between the BSW process and the linear instability of test fields around the extremal black holes, the latter of which has been recently found by Aretakis.

description: A general approach is derived for constructing an effective spin-orbit Hamiltonian for nonmagnetic materials, which is useful for calculating spin-dependent properties near an arbitrary point in momentum space with pseudospin degeneracy. The formalism is verified through comparisons with other approaches for III-V semiconductors, and its general applicability is illustrated by deriving the spin-orbit interaction and predicting spin lifetimes for strained SrTiO$_3$ and a two-dimensional electron gas in SrTiO$_3$ (such as at the LaAlO$_3$/SrTiO$_3$ interface). These results suggest robust spin coherence and spin transport properties in SrTiO$_3$-based materials at room temperature.

description: We study the properties of nonlinear interference noise (NLIN) in fiber-optic communications systems with large accumulated dispersion. Our focus is on settling the discrepancy between the results of the Gaussian noise (GN) model (according to which NLIN is additive Gaussian) and a recently published time-domain analysis, which attributes drastically different properties to the NLIN. Upon reviewing the two approaches we identify several unjustified assumptions that are key in the derivation of the GN model, and that are responsible for the discrepancy. We derive the true NLIN power and verify that the NLIN is not additive Gaussian, but rather it depends strongly on the data transmitted in the channel of interest. In addition we validate the time-domain model numerically and demonstrate the strong dependence of the NLIN on the interfering channels' modulation format.

title: Wireless networks QoS optimization using coded caching and machine learning algorithms
Creators: name: Khalil, Mohamed
Publisher: name: Memorial University of Newfoundland

description: Proactive caching shows great potential to minimize peak traffic rates by storing popular data, in advance, at different nodes in the network. We study three new angles of proactive caching that were not covered before in the literature. We develop more practical algorithms that bring proactive caching closer to practical wireless networks. The first angle is where the popularities of the cached files are changing over time and the file delivery is asynchronous. We provide an algorithm that minimizes files’ delivery rate under this setting. We show that we can use the file delivery messages to proactively and constantly update the receiver finite caches. We show that this mechanism reduces the downloaded traffic of the network. The proposed scheme uses index coding [1], and app. A to jointly encodes the delivery of different demanded files with the cache updates to other receivers to follow the changes in the file popularities. An offline and online (dynamic) versions of the scheme are proposed, where the offline version requires knowledge of the file popularities across the whole transmission period in advance and the online one requires the file popularities for one succeeding time slot only. The optimal caching for both the offline and online schemes is obtained numerically. The second angle is the study of segmented caching for delay minimization in networks with congested backhaul. Studies have mainly focused on proactively storing popular whole files. For certain categories of files like videos, this is not the best strategy. As videos can be segmented, sending later segments of videos can be less time-critical. Video is expected to constitute 82% of internet traffic by 2020 [2]. We study the effect of segmenting video caching decisions under the assumption that the backhaul is congested. We provide an algorithm for proactive segmented caching that optimizes the choice of segments to be cached to minimize delay and compare the performance to the whole file proactive caching. The third angle focuses on using reinforcement learning for coded caching in networks with changing file popularities. For such a dynamic environment, reinforcement learning has the flexibility to learn the environment and adapt accordingly. We develop a reinforcement learning-based coded caching algorithm and compare its performance to rule-based coded caching.

description: Aims: Many children and young people (CYP) experience disadvantages that might increase their risk of becoming homelessness. The literature outlines how homeless prevention efforts ought to focus on addressing structural causes for homelessness such as housing availability and affordability alongside prevention efforts for those at imminent risk of becoming homeless. Healthcare professionals have a duty to help prevent homelessness. There are no known studies that explore clinical psychologists (CP’s) views and experiences of preventing homelessness for CYP. The current study reviewed CPs positions on what the profession can do to help prevent homelessness for CYP and families. Method: Eleven CPs experienced in working with CYP were interviewed using a semi-structured format. Thematic analysis was utilised to identify CPs views and experiences related to helping to prevent homeless for CYP. Results: Two themes were identified (1) ‘Different layers of Impact and Intervention’ describing CPs ideas about identifying and assessing for various risks factors for homelessness in CYP and different ways CPs believe they can help to prevent homelessness. Some participants talked about how relative power such as how wider society imposes on CYP, psychologists, and team members capacity to change circumstances for CYP related to homelessness. Participants considered how to be strategic with ways they could advocate for CYP as well as highlighting CYP’s and communities’ resources. The findings also highlighted taking a collaborative and holistic approach to supporting CYP. Of note there were differences of ideas among participants about the role of CPs (2) ‘Personal and Professional Influences’ summarises participants experiences and resources that inform their ideas and practices related to preventing homelessness. How participants view the role of CPs and having support and direction appeared to be factors that can influence prevention work. Conclusion: The findings support that CPs have a role in addressing prevention of homelessness for CYP and families and more can be done to support CPs in implementing interventions that address factors impacting risks of homelessness.

description: We examine the stability and dynamics of a family of crossed dark solitons in a harmonically confined Bose-Einstein condensate in two dimensions. Working in a regime where the fundamental snake instability is suppressed, we show the existence of an instability which leads to an interesting collapse and revival of the initial state for the fundamental case of two crossed solitons. The instability originates from the singular point where the solitons cross, and we characterise it by examining the Bogoliubov spectrum. Finally, we extend the treatment to systems of higher symmetry.

Im Vorfeld des siebten Jahrestages seiner Machtergreifung erklärte – jetzt Präsident – General Pervez Musharraf im pakistanischen Kur- und Ferienort Murree: „Wer auch immer Pakistan national oder international etwas anhaben will, muss zuerst mich bekämpfen“. Pakistans Präsident in Uniform macht damit zweierlei klar: Erstens ist er von sich und der von ihm ausgewählten Regierung unter Premierminister Shaukat Aziz zufrieden. Zweitens gibt es mit ihm keinen Richtungswechsel in der Wirtschafts-, Entwicklungs- und Militärpolitik. „Es gibt keinen Kompromiss in der Stabilitäts- und Interessenpolitik des Landes“, so Musharraf. Diese seien durch die regierungseigen Entwicklungsprojekte und Initiativen zur Generierung von Wohlstand umschrieben.

Our focus is on models whose signals are driven by colored production. We present projections of the upper limit and discovery reach in the gluino-neutralino (for both light and heavy flavor decays), squark-neutralino, and gluino-squark Simplified Model planes. Depending on the model a jets + MET, mono-jet, or same-sign di-lepton search is applied. The impact of pileup is explored. This study utilizes the Snowmass backgrounds and combined detector. Assuming 3000 fb^{-1} of integrated luminosity, a gluino that decays to light flavor quarks can be discovered below 2.3 TeV at the 14 TeV LHC and below 11 TeV at a 100 TeV machine.

description: We present an extension of our recently introduced molecular density functional theory of water [G. Jeanmairet et al., J. Phys. Chem. Lett. 4, 619, 2013] to the solvation of hydrophobic solutes of various sizes, going from angstroms to nanometers. The theory is based on the quadratic expansion of the excess free energy in terms of two classical density fields, the particle density and the multipolar polarization density. Its implementation requires as input a molecular model of water and three measurable bulk properties, namely the structure factor and the k-dependent longitudinal and transverse dielectric susceptibilities. The fine three-dimensional water structure around small hydrophobic molecules is found to be well reproduced. In contrast the computed solvation free-energies appear overestimated and do not exhibit the correct qualitative behavior when the hydrophobic solute is grown in size. These shortcomings are corrected, in the spirit of the Lum-Chandler-Weeks theory, by complementing the functional with a truncated hard-sphere functional acting beyond quadratic order in density. It makes the resulting functional compatible with the Van-der-Waals theory of liquid-vapor coexistence at long range. Compared to available molecular simulations, the approach yields reasonable solvation structure and free energy of hard or soft spheres of increasing size, with a correct qualitative transition from a volume-driven to a surface-driven regime at the nanometer scale.

description: We investigated the propagation of a squeezed optical field, generated via the polarization self-rotation (PSR) effect, with a sinusoidally-modulated degree of squeezing through an atomic medium with anomalous dispersion. We observed the advancement of the signal propagating through a resonant Rb vapor compared to the reference signal, propagating in air. The measured advancement time grew linearly with atomic density, reaching a maximum of $11 \pm 1~μ$s, which corresponded to a negative group velocity of $v_g\approx - 7,000~$m/s. We also confirmed that the increasing advancement was accompanied by a reduction of output squeezing levels due to optical losses, in good agreement with theoretical predictions.

description: A QCD factorization formalism was recently proposed for evaluating heavy quarkonium production at large $p_T$ at collider energies. With systematically calculated short-distance partonic hard parts and evolution kernels of fragmentation functions (FFs), the predictive power of this factorization approach relies on our knowledge of a large number of universal FFs at an input factorization scale $μ_0\gtrsim 2m_Q$ with heavy quark mass $m_Q$. With the large heavy quark mass, the relative motion of the heavy quark pair inside a heavy quarkonium is effectively non-relativistic. We evaluate these universal input FFs using non-relativistic QCD (NRQCD) factorization, and express the large number of FFs in terms of a few universal NRQCD long-distance matrix elements (LDMEs) with perturbatively calculated coefficients. We derive complete contributions to the single-parton FFs at both ${\cal O}(α_s)$ and ${\cal O}(α_s^2)$, and the heavy quark pair FFs at ${\cal O}(α_s)$. We present detailed derivation for all contributions involving LDMEs of $S$-wave NRQCD $Q\bar{Q}$-states ($P$-wave contributions in a companion paper). Our results bridge the gap between the QCD factorization formalism and its phenomenological applications.

description: A formulation of singular classical theories (determined by degenerate Lagrangians) without constraints is presented. A partial Hamiltonian formalism in the phase space having an initially arbitrary number of momenta (which can be smaller than the number of velocities) is proposed. The equations of motion become first-order differential equations, and they coincide with those of multi-time dynamics, if a certain condition is imposed. In a singular theory, this condition is fulfilled in the case of the coincidence of the number of generalized momenta with the rank of the Hessian matrix. The noncanonical generalized velocities satisfy a system of linear algebraic equations, which allows an appropriate classification of singular theories (gauge and nongauge). A new antisymmetric bracket (similar to the Poisson bracket) is introduced, which describes the time evolution of physical quantities in a singular theory. The origin of constraints is shown to be a consequence of the (unneeded in our formulation) extension of the phase space. In this case the new bracket transforms into the Dirac bracket. Quantization is briefly discussed.

description: Self-propelled point-like particles move along circular trajectories when their translocation velocity is constant and the angular velocity related to their orientation vector is also constant. We investigate the collective behavior of ensembles of such circle swimmers by Brownian dynamics simulations. If the particles interact via a "velocity-trajectory coordination" rule within neighboring particles, a self-organized vortex pattern emerges. This vortex pattern is characterized by its particle-density correlation function $G_ρ$, the density correlation function $G_c$ of trajectory centers, and an order parameter $S$ representing the degree of the aggregation of the particles. Here, we systematically vary the system parameters, such as the particle density and the interaction range, in order to reveal the transition of the system from a light-vortex-dominated to heavy-vortex-dominated state, where vortices contain mainly a single and many self-propelled particles, respectively. We also study a semi-dilute solution of curved, sinusoidal-beating flagella, as an example of circling self-propelled particles with explicit propulsion mechanism and excluded-volume interactions. Our simulation results are compared with previous experimental results for the vortices in sea-urchin sperm solutions near a wall. The properties of the vortices in simulations and experiments are found to agree quantitatively.

description: We present a global analysis of the B->K*(->K pi)mu+mu- decay using the recent LHCb measurements of the primary observables P_{1,2} and P'_{4,5,6,8}. Some of them exhibit large deviations with respect to the SM predictions. We explain the observed pattern of deviations through a large New Physics contribution to the Wilson coefficient of the semileptonic operator O9. This contribution has an opposite sign to the SM one, i.e., reduces the size of this coefficient significantly. A good description of data is achieved by allowing for New Physics contributions to the Wilson coefficients C7 and C9 only. We find a 4.5 sigma deviation with respect to the SM prediction, combining the large-recoil B->K*(->K pi)mu+mu- observables with other radiative processes. Once low-recoil observables are included the significance gets reduced to 3.9 sigma. We have tested different sources of systematics, none of them modifying our conclusions significantly. Finally, we propose additional ways of measuring the primary observables through new foldings.

description: El trastorno del espectro autista (TEA), es una afección neurológica y del desarrollo, la cual afecta la manera en que una persona percibe y entiende el mundo que le rodea, y es para toda la vida. Este trastorno adquiere el nombre de "espectro" ya que afecta a las personas de distintas formas y en diferentes grados, sin embargo, todas las personas diagnosticadas con autismo presentan dificultad en la comunicación, la interacción social, aprendizaje y la imaginación social; muchas personas con autismo también suelen tener hiper o hiposensibilidad sensorial e involucran patrones de conducta restringidos y repetitivos como lo son las conductas disruptivas y estereotipadas. (Medlineplus, 2020). El uso de lenguaje de las personas con autismo depende de su desarrollo intelectual y social, algunas personas que presentan limitación en la comunicación verbal, manifiestan no sólo dificultad en las habilidades comunicativas, sino también en la interacción social, la cual conlleva a la persona a presentar ciertos patrones de conductas desafiantes consecuentes a querer comunicarse de alguna manera. Con base en ello, se puede decir que existen diversos tipos de comunicación. Independientemente de que una persona pueda tener o no desarrollado su lenguaje verbal, puede manifestarse o crear comunicación de distintas formas, ya sea por medio de palabras, señas, dibujos/imágenes, o incluso usando la tecnología; asimismo, podemos decir que las conductas son estilos o una de las distintas formas de comunicación que existen y que éstas generalmente suelen manifestar conformidad e inconformidad ante un estímulo y/o entorno determinado.

description: We study theoretically the ground states of topological defects in a spinor four-component condensate of cold indirect excitons. We analyze possible ground state solutions for different configurations of vortices and half-vortices. We show that if only Rashba or Dreselhaus spin-orbit interaction (SOI) for electrons is present the stable states of topological defects can represent a cylindrically symmetric half-vortex or half vortex-antivortex pairs, or a non-trivial pattern with warped vortices. In the presence of both of Rashba and Dresselhaus SOI the ground state of a condensate represents a stripe phase and vortex type solutions become unstable.

description: We present optical spectroscopy and optical/near-IR photometry of 31 host galaxies of hydrogen-poor superluminous supernovae (SLSNe), including 15 events from the Pan-STARRS1 Medium Deep Survey. Our sample spans the redshift range 0.1 < z < 1.6 and is the first comprehensive host galaxy study of this specific subclass of cosmic explosions. Combining the multi-band photometry and emission-line measurements, we determine the luminosities, stellar masses, star formation rates and metallicities. We find that as a whole, the hosts of SLSNe are a low-luminosity ( ~ -17.3 mag), low stellar mass ( ~ 2 x 10^8 M_sun) population, with a high median specific star formation rate ( ~ 2 Gyr^-1). The median metallicity of our spectroscopic sample is low, 12 + log(O/H}) ~ 8.35 ~ 0.45 Z_sun, although at least one host galaxy has solar metallicity. The host galaxies of H-poor SLSNe are statistically distinct from the hosts of GOODS core-collapse SNe (which cover a similar redshift range), but resemble the host galaxies of long-duration gamma-ray bursts (LGRBs) in terms of stellar mass, SFR, sSFR and metallicity. This result indicates that the environmental causes leading to massive stars forming either SLSNe or LGRBs are similar, and in particular that SLSNe are more effectively formed in low metallicity environments. We speculate that the key ingredient is large core angular momentum, leading to a rapidly-spinning magnetar in SLSNe and an accreting black hole in LGRBs.

description: Recently an efficient numerical method has been developed to implement the constraints of crossing symmetry and unitarity on the operator dimensions and OPE coefficients of conformal field theories (CFT) in diverse space-time dimensions. It appears that the calculations can be done only for theories lying at the boundary of the allowed parameter space. Here it is pointed out that a similar method can be applied to a larger class of CFT's, whether unitary or not, and no free parameter remains, provided we know the fusion algebra of the low lying primary operators. As an example we calculate using first principles, with no phenomenological input, the lowest scaling dimensions of the local operators associated with the Yang-Lee edge singularity in three and four space dimensions. The edge exponents compare favorably with the latest numerical estimates. A consistency check of this approach on the 3d critical Ising model is also made.
