description: In global supersymmetric Wess-Zumino models with minimal Kähler potentials, F-type supersymmetry breaking always yields instability or continuous degeneracy of non-supersymmetric vacua. As a generalization of the original O'Raifeartaigh's result, the existence of instability or degeneracy is true to any higher order corrections at tree level for models even with non-renormalizable superpotentials. The degeneracy generically coincides the R-axion direction under some assumptions of R-charge assignment, but generally requires neither R-symmetries nor any assumption of generic superpotentials. The result also confirms the well-known fact that tree level supersymmetry breaking is a very rare occurrence in global supersymmetric theories with minimal Kähler potentials. The implication for effective field theory method in the landscape is discussed and we point out that choosing models with minimal Kähler potentials may result in unexpected answers to the vacuum statistics. Supergravity theories or theories with non-minimal Kähler potentials in general do not suffer from the existence of instability or degeneracy. But very strong gauge dynamics or small compactification dimension reduces the Kähler potential from non-minimal to minimal, and gravity decoupling limit reduces supergravity to global supersymmetry. Instability or degeneracy may appear in these limits. Away from these limits, a large number of non-SUSY vacua may still be found in an intermediate region.

description: Several H2CS ortho and para transitions have been observed toward interstellar molecular clouds, including cold, dark clouds and star-forming regions. H2CS fractional abundances f(H2CS) about 1-2 10 to the -9th relative to molecular hydrogen toward TMC-1, Orion A, and NGC 7538, and about 5 10 to the -10th for L134N are derived. The H2CS ortho-to-para ratios in TMC-1 are about 1.8 toward the cyanopolyyne peak and the ammonia peak, which may indicate the thermalization of H2CS on 10 K grains. A ratio of about 3, the statistical value, for Orion (3N, 1E) and NGC 7538 is derived, while a value of about 2 for Orion (KL) is found.
Muon anomalies and the $SU(5)$ Yukawa relations

description: We show that, within the framework of $SU(5)$ Grand Unified Theories (GUTs), multiple vector-like families at the GUT scale which transform under a gauged $U(1)'$ (under which the three chiral families are neutral) can result in a single vector-like family at low energies which can induce non-universal and flavourful $Z'$ couplings, which can account for the B physics anomalies in $R_{K^{(*)}}$. In such theories, we show that the same muon couplings which explain $R_{K^{(*)}}$ also correct the Yukawa relation $Y_e=Y_d^T$ in the muon sector without the need for higher Higgs representations. To illustrate the mechanism, we construct a concrete a model based on $SU(5)\times A_4 \times Z_3\times Z_7$ with two vector-like families at the GUT scale, and two right-handed neutrinos, leading to a successful fit to quark and lepton (including neutrino) masses, mixing angles and CP phases, where the constraints from lepton flavour violation require $Y_e$ to be diagonal.

On the modeling of green corridors with Agent-Based simulations

Biodiversity

description: Among those strategies that try to safeguard biodiversity by intervening on habitat fragmentation, the so-called “wildlife corridors” are of utmost importance. These green corridors generally consist on infrastructures realized to connect habitats and natural areas; however, as they are often time- and resource-consuming, their traditionally heuristic design has been recently coupled with different mathematical models, which can study and possibly anticipate the corridors perturbative effects on each ecological context.
 In the present project, I address such issue by presenting the design and implementation of a computational model which makes use of the Agent-Based paradigm with BDI architecture. In the author’s aims, such combination of modeling characteristics should allow for a close replica of animal behaviors, so that the overall system could be realistically modeled and inquired. Moreover, said approach should prove itslef to be flexible and easily manageable even by researchers who are not experts of AI techniques, resulting in a better collaboration among biologists and theoreticians. Finally, a toy model is presented and its preliminary results are analyzed discussed.
Fast, exact (but unstable) spin spherical harmonic transforms

description: In many applications data are measured or defined on a spherical manifold; spherical harmonic transforms are then required to access the frequency content of the data. We derive algorithms to perform forward and inverse spin spherical harmonic transforms for functions of arbitrary spin number. These algorithms involve recasting the spin transform on the two-sphere S^2 as a Fourier transform on the two-torus T^2. Fast Fourier transforms are then used to compute Fourier coefficients, which are related to spherical harmonic coefficients through a linear transform. By recasting the problem as a Fourier transform on the torus we appeal to the usual Shannon sampling theorem to develop spherical harmonic transforms that are theoretically exact for band-limited functions, thereby providing an alternative sampling theorem on the sphere. The computational complexity of our forward and inverse spin spherical harmonic transforms scale as O(L^3) for any arbitrary spin number, where L is the harmonic band-limit of the spin function on the sphere. Numerical experiments are performed and unfortunately the forward transform is found to be unstable for band-limits above L~32. The instability is due to the poorly conditioned linear system relating Fourier and spherical harmonic coefficients. The inverse transform is expected to be stable, although it is not possible to verify this hypothesis.

description: In this note we prove that the solution of the stationary and the instationary Stokes equations subject to perfect slip boundary conditions on a 2D wedge domain admits optimal regularity in the $L^p$-setting, i.p. it is $W^{2,p}$ in space. This improves known results in the literature to a large extend. For instance, in [21, Theorem 1.1 and Corollary 3] it is proved that the Laplace and the Stokes operator in the underlying setting have maximal regularity. In that result the range of p admitting $W^{2,p}$ regularity, however, is restricted to the interval $10$, depending on the opening angle of the wedge. This note gives a detailed answer to the question, whether the optimal Sobolev regularity extends to the full range $1

description: We study for the first time the stability against scalar perturbations, and we compute the spectrum of quasinormal modes of three-dimensional charged black holes in Einstein-power-Maxwell non-linear electrodynamics assuming running couplings. Adopting the 6th order WKB approximation we investigate how the running of the couplings change the spectrum of the classical theory. Our results show that all modes corresponding to non-vanishing angular momentum are unstable both in the classical theory and with the running of the couplings, while the fundamental mode can be stable or unstable depending on the running parameter and the electric charge.

description: There is a large variety of types of research software at different stages of evolution. Due to the nature of research and its software, existing models from software engineering often do not cover the unique needs of RSE projects.  This lack of clear models can confuse potential software users, developers, funders, and other stakeholders who need to understand the state of a particular software project, such as when deciding to use it, contribute to it, or fund it. We present work performed by a group consisting of both software engineering researchers (SERs) and research software engineers (RSEs), who met at a Dagstuhl seminar, to collaborate on these ideas.

Through our collaboration, we found many of our terminologies and definitions often vary, for example one person may consider a software project to be early-stage or in maintenance mode, whilst another person might consider the same software to be inactive or failed. Because of this, we explored concepts such as software maturity, intended audience, and intended future use.

In this poster, we will present a working categorization of research software types, as well as an abstract software lifecycle that can be applied and customized to suit a wide variety of research software types.  Such a model can be used to make decisions and guide development standards that may vary by stage and by team.  We also are seeking community input on improvements of these two artifacts for future iterations.
Gas-Liquid Nucleation in Two Dimensional System

description: We study the nucleation of the liquid phase from a supersaturated vapor in two dimensions (2D). Using different Monte Carlo simulation methods, we calculate the free energy barrier for nucleation, the line tension and also investigate the size and shape of the critical nucleus. The study is carried out at an intermediate level of supersaturation(away from the spinodal limit). In 2D, a large cut-off in the truncation of the Lennard-Jones (LJ) potential is required to obtain converged results, whereas low cut-off (say, $2.5σ$ is generally sufficient in three dimensional studies, where $σ$ is the LJ diameter) leads to a substantial error in the values of line tension, nucleation barrier and characteristics of the critical cluster. It is found that in 2D, the classical nucleation theory (CNT) fails to provide a reliable estimate of the free energy barrier. It underestimates the barrier by as much as 70% at the saturation-ratio S=1.1 (defined as S=P/PC, where PC is the coexistence pressure at reduced temperature $T^{\star}= 0.427$). Interestingly, CNT has been found to overestimate the nucleation free energy barrier in three dimensional (3D)systems near the triple point. In fact, the agreement with CNT is worse in 2D than in 3D. Moreover, the existing theoretical estimate of the line tension overestimates the value significantly.

description: Since subsentential alignment is critically important to the translation quality of an Example-Based Machine Translation (EBMT) system which operates by finding and combining phrase-level matches against the training examples, we recently decided to develop a new alignment algorithm for the purpose of improving the EBMT system’s performance. Unlike most algorithms in the literature, this new Symmetric Probabilistic Alignment (SPA) algorithm treats the source and target languages in a symmetric fashion. In this paper, we describe our basic algorithm and some extensions for using context and positional information, compare its alignment accuracy with IBM Model 4, and report on experiments in which either IBM Model 4 or SPA alignments are substituted for the aligner currently built into the EBMT system. Both Model 4 and SPA are significantly better than the internal aligner and SPA slightly outperforms Model 4 despite being handicapped by incomplete integration with EBMT.
Josephson Current and Multiple Andreev Reflections in Graphene SNS Junctions

description: The Josephson Effect and Superconducting Proximity Effect were observed in Superconductor -Graphene-Superconductor (SGS) Josephson junctions with coherence lengths comparable to the distance between the superconducting leads. By comparing the measured temperature and doping dependence of the supercurrent and the proximity induced sub-gap features (multiple Andreev reflections) to theoretical predictions we find that, contrary to expectations, the ballistic transport model fails to describe the SGS junctions. In contrast, the diffusive junction model yields close quantitative agreement with the results. This conclusion is consistent with transport measurements in the normal state, which yield mean free paths in the graphene link that are much shorter than the junction length. We show that all devices fabricated on SiO2 substrates so far (our own as well as those reported by other groups) fall in the diffusive junction category.

Creativity in Fundraising on Non-Governmental Organisations

description: This research aims to understand the importance of creativity in fundraising applied to a non-governmental organization (NGO) that works together with the health system (Ronald McDonald Foundation, Portugal). The research strategy is qualitative through an interview with the Foundation’s top managers. Regarding the role and the importance of interviews, noticed that in depth interviews have already proved their worth in research. The results of this study prove that creativity, individual and organizational was the lever in all the campaigns they have done in the past. However, the times are changing and there’s the need to implement new ways to generate new ideas, namely on the digital area, on line commerce and partnerships with companies of e-commerce. Thus, (1) there are some aspects of the individual, known as the P’s of creativity that determine our capacity for being creative: the person or personality; the process; the place; the product or service and the capacity of persuasion. Creative people can change the way other people think and they potential the creative process with attitudes and values), (2) foundations and NGO’s always played a very important role in the society, not only because they work for a common good but also for decreasing social imbalances in the community by helping the most needed people. These organizations are also facing the challenges of a global virus and being aware of the economic impact in the people lives and (3) fundraising and crowdfunding are the two ways of financing the NGO’s in order to allow these organizations to develop their mission. The global financial difficulties present and ahead, impose the need of being creative, because there will be more people needing help and the sponsors and donators won’t have the same availability.

We investigate the combinatorial species of split graphs, providing species-theoretic generalizations of enumerative results due to Bína and Přibil (2015), Cheng, Collins, and Trenk (2016), and Collins and Trenk (2018). In both the labeled and unlabeled cases, we give asymptotic results on the number of split graphs, of unbalanced split graphs, and of bicolored graphs, including proving the conjecture of Cheng, Collins, and Trenk (2016) that almost all split graphs are balanced.

description: This research paper aims to establish a connection between the concept of Personal Branding and Social Media, understanding how in the 21st-century people do their personal branding through Social Media, taking into account the role of Digital Influencers on Instagram. It is to be expected that these individuals, given their social status, make good personal branding. The methodology approach used was a qualitative one, developed through an interview with 25 questions and counting with 10 responses, half woman, and half male. The interviewees were Portuguese Instagram Influencers. Some conclusions that were possible to draw were that becoming an Influencer is something well thought, people do intentional personal branding, they often plan their content, consider the impact of their actions on others, the number of followers is important when addresses to job opportunities. In the perspective on how Influencers build that online presence, the main factors mentioned are consistency, authenticity/genuineness, and interaction with the audience.

description: The solvability of a delay differential equation arising in the construction of quadratic cost functionals, i.e. Lyapunov functionals, for a linear time-delay system with a constant and a distributed delay is investigated. We present a delay-free auxiliary ordinary differential equation system with algebraically coupled split-boundary conditions, that characterizes the solutions of the delay differential equation and is used for solution synthesis. A spectral property of the time-delay system yields a necessary and sufficient condition for existence and uniqueness of solutions to the auxiliary system, equivalently the delay differential equation. The result is a tractable analytic solution framework to the delay differential equation.

description: Recent investigations show that conservation laws limit the accuracy of gate operations in quantum computing. The inevitable error under the angular momentum conservation law has been evaluated so far for the CNOT, Hadamard, and NOT gates for spin 1/2 qubits, while the SWAP gate has no constraint. Here, we extend the above results to general single-qubit gates. We obtain an upper bound of the gate fidelity of arbitrary single-qubit gates implemented under arbitrary conservation laws, determined by the geometry of the conservation law and the gate operation on the Bloch sphere as well as the size of the ancilla.

description: This research aims to recognize the influence that creativity units/modules/seminars has on academic performance of students who attend. Consequently, the purpose of this study is to understand the impact that learning creativity has on Porto Accounting and Business School (ISCAP) students’. Therefore, a quantitative methodology was developed through a questionnaire with 240 answers from ISCAP’s students. The data was studied through reliability and explanatory factorial analysis in order to find the relation between the physical environment, learning climate and learner engagement on the performance of students. The results show that the physical environment and learning climate have a positive influence on students’ performance but the same does not happen with the motivation of students. These findings focus on the necessity to improve the students’ engagement. It is recommended that ISCAP will take into account the factors that lead to the referred results so as to reform and develop new ways in which to improve students’ performance through students’ motivation.

description: The benefits and harms of dual antiplatelet therapy (DAPT) continuation with aspirin and clopidogrel beyond 1 year after percutaneous coronary intervention (PCI) with drug-eluting stent (DES) implantation for high ischemic or bleeding risk patients remain unclear. All consecutive patients undergoing PCI were prospectively included in the Fuwai PCI Registry from January 2013 to December 2013. We evaluated 7521 patients who were at high risk for thrombotic or hemorrhagic complications and were events free at 1 year after the index procedure. “TWILIGHT-like” patients with high risk of bleeding or ischemic events were defined by clinical and angiographic criteria. The primary ischemic outcome was major adverse cardiac and cerebrovascular events [MACCE] (a composite of all-cause death, myocardial infarction, or stroke). Median follow-up duration was 2.4 years. The risk of MACCE was significantly lower in DAPT>1-year group (n = 5252) than DAPT≤1-year group (n = 2269) (1.5% vs. 3.8%; hazard ratio [HR]: 0.37; 95% confidence interval [CI]: 0.27–0.50; P < .001). This difference was largely driven by a lower risk of all-cause death. In contrast, the risk of Bleeding Academic Research Consortium (BARC) type 2, 3 or 5 bleeding was statistically similar between the two groups (1.0% vs. 1.1%; HR: 0.80; 95% CI: 0.50–1.28; P = .346). Results were consistent after multivariable regression and propensity-score matching. Prolonged DAPT beyond 1 year after DES implantation resulted in a significantly lower rate of atherothrombotic events, including a mortality benefit, with no higher risk of clinically relevant bleeding in “TWILIGHT-like” patients who were at high-risk for ischemic or bleeding events.

The study was focused on two target groups: - 1 st: students from Vilnius University of Applied Sciences - Group 2: students from Porto Accounting and Business School. For a better analysis and evaluation of the results obtained in the questionnaire, the Lewis Model was used to understand in which cultural categories the countries under study would be inserted and its impact on creativity. The statistical analysis results demonstrate that Lithuanian students show higher average results in the different sub-components of perceived creativity in higher education. However, the results indicate that the view of the concept understanding is close between Portuguese and Lithuanian students. The research that is presented in this paper is the first research related to creativity in education comparing Portugal and Lithuania and it could be a good base for further research of two economically similar yet culturally different countries

Axisymmetric toroidal modes of magnetized neutron stars

description: We calculate axisymmetric toroidal modes of magnetized neutron stars with a solid crust. We assume the interior of the star is threaded by a poloidal magnetic field that is continuous at the surface with the outside dipole field whose strength $B_p$ at the magnetic pole is $B_p\sim 10^{16}$G. Since separation of variables is not possible for oscillations of magnetized stars, we employ finite series expansions of the perturbations using spherical harmonic functions to represent the angular dependence of the oscillation modes. For $B_p\sim 10^{16}$G, we find distinct mode sequences, in each of which the oscillation frequency of the toroidal mode slowly increases as the number of radial nodes of the eigenfunction increases. The frequency spectrum of the toroidal modes for $B_p\sim 10^{16}$G is largely different from that of the crustal toroidal modes of the non-magnetized model, although the frequency ranges are overlapped each other. This suggests that an interpretation of the observed QPOs based on the magnetic toroidal modes may be possible if the field strength of the star is as strong as $B_p\sim 10^{16}$G.

‘I Didn’t Buy it for Myself’ Privacy and Ecommerce Personalization
Creators: name: Cranor, Lorrie Faith
Publisher: name: Carnegie Mellon University
Year: 2003
Subjects: subject: 80399 Computer Software not elsewhere classified
subject: FOS: Computer and information sciences

description: Ecommerce personalization can help web sites build and retain relationships with customers, but it also raises a number of privacy concerns. This paper outlines the privacy risks associated with personalization and describes a number of approaches to personalization system design that can reduce these risks. This paper also provides an overview of the fair information practice principles and discusses how they may be applied to the design of personalization systems, and introduces privacy laws and self-regulatory guidelines relevant to personalization. Privacy risks can be reduced when personalization system designs allow for pseudonymous interactions, client-side data stores, and task-based personalization. In addition, interfaces that allow users to control the collection and use of their profile information can further ease privacy concerns.

On Freud's superpotential in General Relativity and in Einstein-Cartan theory

description: The identification of a suitable gravitational energy in theories of gravity has a long history, and it is well known that a unique answer cannot be given. In the first part of this paper we present a streamlined version of the derivation of Freud's superpotential in general relativity. It is found if we once integrate the gravitational field equation by parts. This allows us to extend these results directly to the Einstein-Cartan theory. Interestingly, Freud's original expression, first stated in 1939, remains valid even when considering gravitational theories in Riemann-Cartan or, more generally, in metric-affine spacetimes.

description: Sustainable entrepreneurship pursues a triple agenda approximate economic, social, and ecological aspirations. We can agree upon the fact that environmental awareness is becoming more and more important on the global market and among people in general. Companies all over the world, have a bigger awareness, addressing more ecological concerns on their products, in order to become greener for consumers. This makes sustainable entrepreneurship an important topic in society and for the economy in general. This article is about sustainable entrepreneurship and the barriers that are connected to it, along with the comparison of two European Union countries, Portugal, and Slovenia, regarding the perceived obstacles and risk for starting a sustainable business. For this, we did use quantitative data from Eurobarometer with the intention to measure how much weight the upcoming entrepreneurship put on the conservation of nature and how much they think about environmental sustainability. We obtained the data that show the level of importance of ecology in business for the entrepreneurs in Portugal, for the ones in Slovenia, and in this case, we can also compare the data with the European Union average.

description: This paper deals with a universal coding problem for a certain kind of multiterminal source coding network called a generalized complementary delivery network. In this network, messages from multiple correlated sources are jointly encoded, and each decoder has access to some of the messages to enable it to reproduce the other messages. Both fixed-to-fixed length and fixed-to-variable length lossless coding schemes are considered. Explicit constructions of universal codes and the bounds of the error probabilities are clarified by using methods of types and graph-theoretical analysis.

Numerical methods for thermally stressed shallow shell equations

Publisher: name: arXiv
Year: 2017
Subjects: subject: Numerical Analysis (math.NA)
subject: FOS: Mathematics

description: We develop efficient and accurate numerical methods to solve a class of shallow shell problems of the von Karman type. The governing equations form a fourth-order coupled system of nonlinear biharnomic equations for the transverse deflection and Airy's stress function. A second-order finite difference discretization with three iterative methods (Picard, Newton and Trust-Region Dogleg) are proposed for the numerical solution of the nonlinear PDE system. Three simple boundary conditions and two application-motivated mixed boundary conditions are considered. Along with the nonlinearity of the system, boundary singularities that appear when mixed boundary conditions are specified are the main numerical challenges. Two approaches that use either a transition function or local corrections are developed to deal with these boundary singularities. All the proposed numerical methods are validated using carefully designed numerical tests, where expected orders of accuracy and rates of convergence are observed. A rough run-time performance comparison is also conducted to illustrate the efficiency of our methods. As an application of the methods, a snap-through thermal buckling problem is considered. The critical thermal loads of shell buckling with various boundary conditions are numerically calculated, and snap-through bifurcation curves are also obtained using our numerical methods together with a pseudo-arclength continuation method. Our results are consistent with previous studies.
title: Effect of The Milkyway on Magellanic Cloud Structure

Subjects: subject: Astrophysics and Astronomy

description: This paper was harvested from ArXiv identifier is arXiv:9905305v1
description: A combination of analytic models and n-body simulations implies that the structural evolution of the Large Magellanic Cloud (LMC) is dominated by its dynamical interaction with the Milky Way. Although expected at some level, the scope of the involvement has significant observational consequences. First, LMC disk orbits are torqued out of the disk plane, thickening the disk and populating a spheroid. The torque results from direct forcing by the Milky Way tide and, indirectly, from the drag between the LMC disk and its halo resulting from the induced precession of the LMC disk. The latter is a newly reported mechanism that can affect all satellite interations. However, the overall torque can not isotropize the stellar orbits and their kinematics remains disk-like. Such a kinematic signature is observed for nearly all LMC populations. The extended disk distribution is predicted to increase the microlensing toward the LMC. Second, the disk’s binding energy slowly decreases during this process, puffing up and priming the outer regions for subsequent tidal stripping. Because the tidally stripped debris will be spatially extended, the distribution of stripped stars is much more extended than the HI Magellanic Stream. This is consistent with upper limits to stellar densities in the gas stream and suggests a different strategy for detecting the stripped stars. And, finally, the mass loss over several LMC orbits is predicted by n-body simulation and the debris extends to tens of kiloparsecs from the tidal boundary. Although the overall space density of the stripped stars is low, possible existence of such intervening populations have been recently reported and may be detectable using 2MASS.

description: From the music we listen to, to the door we open at work and the chair we sit on right now, creativity is all around us. It has a great contribution in our everyday lives, as nowadays more and more people strive to develop both their imagination and inventiveness. An individual who has nurtured his creativity has an advantage over a person who did not. He or she might bring up an unusual solution, yet effective for a difficult problem, create something unseen or unheard before or even design a new and innovative product - but creativity does not imply an artistic or world-changing creation. Everyday tasks require creativity, therefore almost every individual has developed his inner creativeness to a certain level. “Creative entrepreneurship” is a term which refers to business activity within a creative sector and refers to investment in the entrepreneur’s or others’ talent. The aim of this paper is to offer an overview on creativity and clarify what exactly means to be creative, and to contrast the differences between a regular entrepreneur and one who performs in a creative industry.

description:  Data structures such as *BMDs, HDDs, and K*BMDs provide compact representations for functions which map Boolean vectors into integer values, but not floating point values. In this paper, we propose a new data structure, called Multiplicative Power Hybrid Decision Diagrams (*PHDDs), to provide a compact representation for functions that map Boolean vectors into integer or floating point values. The size of the graph to represent the IEEE floating point encoding is linear with the word size. The complexity of floating point multiplication grows linearly with the word size. The complexity of floating point addition grows exponentially with the size of the exponent part, but linearly with the size of the mantissa part. We applied *PHDDs to verify integer multipliers and floating point multipliers before the rounding stage, based on a hierarchical verification approach. For integer multipliers, our results are at least 6 times faster than *BMDs. Previous attempts at verifying floating point multipliers required manual intervention. We verified floating point multipliers before the rounding stage automatically.
