description: Motivated by an important recent experiment [Deng et al., Science 354, 1557 (2016)], we theoretically consider the interplay between Andreev bound states(ABSs) and Majorana bound states(MBSs) in quantum dot-nanowire semiconductor systems with proximity-induced superconductivity(SC), spin-orbit coupling and Zeeman splitting. The dot induces ABSs in the SC nanowire which show complex behavior as a function of Zeeman splitting and chemical potential, and the specific question is whether two such ABSs can come together forming a topological MBS. We consider physical situations involving the dot being non-SC, SC, or partially SC. We find that the ABSs indeed tend to coalesce together producing near-zero-energy midgap states as Zeeman splitting and/or chemical potential are increased, but this mostly happens in the non-topological regime although there are situations where the ABSs could come together forming a topological MBS. The two scenarios(two ABSs forming a near-zero-energy non-topological ABS or a zero-energy topological MBS) are difficult to distinguish by tunneling conductance spectroscopy due to essentially the same signatures. Theoretically we distinguish them by knowing the critical Zeeman splitting for the topological quantum phase transition or by calculating the topological visibility. We find that the "sticking together" propensity of ABSs to produce a zero-energy midgap state is generic in class D systems, and by itself says nothing about the topological nature of the underlying SC nanowire. One must use caution in interpreting tunneling conductance measurements where the midgap sticking-together behavior of ABSs cannot be construed as definitive evidence for topological SC with non-Abelian MBSs. We also suggest some experimental techniques for distinguishing between trivial and topological ZBCPs.

description: This paper analyses the world web of mergers and acquisitions (M&As) using a complex network approach. We use data of M&As to build a temporal sequence of binary and weighted-directed networks for the period 1995-2010 and 224 countries (nodes) connected according to their M&As flows (links). We study different geographical and temporal aspects of the international M&A network (IMAN), building sequences of filtered sub-networks whose links belong to specific intervals of distance or time. Given that M&As and trade are complementary ways of reaching foreign markets, we perform our analysis using statistics employed for the study of the international trade network (ITN), highlighting the similarities and differences between the ITN and the IMAN. In contrast to the ITN, the IMAN is a low density network characterized by a persistent giant component with many external nodes and low reciprocity. Clustering patterns are very heterogeneous and dynamic. High-income economies are the main acquirers and are characterized by high connectivity, implying that most countries are targets of a few acquirers. Like in the ITN, geographical distance strongly impacts the structure of the IMAN: link-weights and node degrees have a non-linear relation with distance, and an assortative pattern is present at short distances.

description: A class of graphs is $χ$-bounded if there exists a function $f:\mathbb N\rightarrow \mathbb N$ such that for every graph $G$ in the class and an induced subgraph $H$ of $G$, if $H$ has no clique of size $q+1$, then the chromatic number of $H$ is less than or equal to $f(q)$. We denote by $W_n$ the wheel graph on $n+1$ vertices. We show that the class of graphs having no vertex-minor isomorphic to $W_n$ is $χ$-bounded. This generalizes several previous results; $χ$-boundedness for circle graphs, for graphs having no $W_5$ vertex-minors, and for graphs having no fan vertex-minors.

description: We theoretically investigate the dynamics of a floating lipid bilayer membrane coupled with a two-dimensional cytoskeleton network, taking into explicitly account the intermonolayer friction, the discrete lattice structure of the cytoskeleton, and its prestress. The lattice structure breaks lateral continuous translational symmetry and couples Fourier modes with different wavevectors. It is shown that within a short time interval a long-wavelength deformation excites a collection of modes with wavelengths shorter than the lattice spacing. These modes relax slowly with a common renormalized rate originating from the long-wavelength mode. As a result, and because of the prestress, the slowest relaxation is governed by the intermonolayer friction. Reversely, and most interestingly, forces applied at the scale of the cytoskeleton for a sufficiently long time can cooperatively excite large-scale modes.

description: At the forefront of nanochemistry, there exists a research endeavor centered around intermetallic nanocrystals, which are unique in terms of long-range atomic ordering, well-defined stoichiometry, and controlled crystal structure. In contrast to alloy nanocrystals with no atomic ordering, it has been challenging to synthesize intermetallic nanocrystals with a tight control over their size and shape. This review article highlights recent progress in the synthesis of intermetallic nanocrystals with controllable sizes and well-defined shapes. We begin with a simple analysis and some insights key to the selection of experimental conditions for generating intermetallic nanocrystals. We then present examples to highlight the viable use of intermetallic nanocrystals as electrocatalysts or catalysts for various reactions, with a focus on the enhanced performance relative to their alloy counterparts that lack atomic ordering. We conclude with perspectives on future developments in the context of synthetic control, structure-property relationship, and application.

description: The Internet of Things (IoT) being a promising technology of the future is expected to connect billions of devices. The increased number of communication is expected to generate mountains of data and the security of data can be a threat. The devices in the architecture are essentially smaller in size and low powered. Conventional encryption algorithms are generally computationally expensive due to their complexity and requires many rounds to encrypt, essentially wasting the constrained energy of the gadgets. Less complex algorithm, however, may compromise the desired integrity. In this paper we propose a lightweight encryption algorithm named as Secure IoT (SIT). It is a 64-bit block cipher and requires 64-bit key to encrypt the data. The architecture of the algorithm is a mixture of feistel and a uniform substitution-permutation network. Simulations result shows the algorithm provides substantial security in just five encryption rounds. The hardware implementation of the algorithm is done on a low cost 8-bit micro-controller and the results of code size, memory utilization and encryption/decryption execution cycles are compared with benchmark encryption algorithms. The MATLAB code for relevant simulations is available online at https://goo.gl/Uw7E0W.

description: Starting from an idea of S.L. Adler~\cite{Adler2015}, we develop a novel model of gravity-induced spontaneous wave-function collapse. The collapse is driven by complex stochastic fluctuations of the spacetime metric. After deriving the fundamental equations, we prove the collapse and amplification mechanism, the two most important features of a consistent collapse model. Under reasonable simplifying assumptions, we constrain the strength $ξ$ of the complex metric fluctuations with available experimental data. We show that $ξ\geq 10^{-26}$ in order for the model to guarantee classicality of macro-objects, and at the same time $ξ\leq 10^{-20}$ in order not to contradict experimental evidence. As a comparison, in the recent discovery of gravitational waves in the frequency range 35 to 250 Hz, the (real) metric fluctuations reach a peak of $ξ\sim 10^{-21}$.

description: We present multi-wavelength observations and modeling of the exceptionally bright long $γ$-ray burst GRB 160625B. The optical and X-ray data are well-fit by synchrotron emission from a collimated blastwave with an opening angle of $θ_j\approx 3.6^\circ$ and kinetic energy of $E_K\approx 2\times10^{51}$ erg, propagating into a low density ($n\approx 5\times10^{-5}$ cm$^{-3}$) medium with a uniform profile. The forward shock is sub-dominant in the radio band; instead, the radio emission is dominated by two additional components. The first component is consistent with emission from a reverse shock, indicating an initial Lorentz factor of $Γ_0\gtrsim 100$ and an ejecta magnetization of $R_B\approx 1-100$. The second component exhibits peculiar spectral and temporal evolution and is most likely the result of scattering of the radio emission by the turbulent Milky Way interstellar medium (ISM). Such scattering is expected in any sufficiently compact extragalactic source and has been seen in GRBs before, but the large amplitude and long duration of the variability seen here are qualitatively more similar to extreme scattering events previously observed in quasars, rather than normal interstellar scintillation effects. High-cadence, broadband radio observations of future GRBs are needed to fully characterize such effects, which can sensitively probe the properties of the ISM and must be taken into account before variability intrinsic to the GRB can be interpreted correctly.

description: We live in time, when all the clubs try to be the best, the most successful,... and to beat others. Nowadays we know various systems for monitoring the statistics and progress of athletes; but all of that systems are very expensive and sometimes they are now very accurate. That is why we wanted to design a belt for monitoring the statistics of athletes. We wanted our system to enable simple, cheaper and efficient training monitoring. With system like that, monitoring of progress with various data could be brought to smaller clubs, that can not monitor such statistics without system like that. The system, which we developed at the time of our research, allows us to monitor the current position of the athlete on the field, athlete's acceleration, heart rate and locations where player is most often positioned. System also calculates calories burned during training. During development of the system, we encountered several different approaches to monitor statistics. In the research project, we investigated and described the problems, advantages and disadvantages of various ways of locating a player, measuring and transmitting data. We also described the most efficient way of processing data and which of the components are the most effective and precise for use in such system.

description: This paper deals with the discrete counterpart of 2D elliptic model problems rewritten in terms of Boundary Integral Equations. The study is done within the framework of Isogeometric Analysis based on B-splines. In such a context, the problem of constructing appropriate, accurate and efficient quadrature rules for the Symmetric Galerkin Boundary Element Method is here investigated. The new integration schemes, together with row assembly and sum factorization, are used to build a more efficient strategy to derive the final linear system of equations. Key ingredients are weighted quadrature rules tailored for B--splines, that are constructed to be exact in the whole test space, also with respect to the singular kernel. Several simulations are presented and discussed, showing accurate evaluation of the involved integrals and outlining the superiority of the new approach in terms of computational cost and elapsed time with respect to the standard element-by-element assembly.

In our study, we discover two new $A_n$ ${}_{12}V_{11}$ transformation formulas, that reduce to two new $A_n$ extensions of Bailey's $_{10}ϕ_9$ transformation formulas when the nome $p$ is $0$, and two multiple series extensions of Frenkel and Turaev's sum.
A Lagrangian fluctuation-dissipation relation for scalar turbulence, II. Wall-bounded flows

description: We derive here Lagrangian fluctuation-dissipation relations for advected scalars in wall-bounded flows. The relations equate the dissipation rate for either passive or active scalars to the variance of scalar inputs from the initial values, boundary values, and internal sources, as those are sampled backward in time by stochastic Lagrangian trajectories. New probabilistic concepts are required to represent scalar boundary conditions at the walls: the boundary local-time density at points on the wall where scalar fluxes are imposed and the boundary first hitting-time at points where scalar values are imposed. These concepts are illustrated both by analytical results for the problem of pure heat conduction and by numerical results from a database of channel-flow flow turbulence, which also demonstrate the scalar mixing properties of near-wall turbulence. As an application of the fluctuation-dissipation relation, we examine for wall-bounded flows the relation between anomalous scalar dissipation and Lagrangian spontaneous stochasticity, i.e. the persistent non-determinism of Lagrangian particle trajectories in the limit of vanishing viscosity and diffusivity. In the first paper of this series, we showed that spontaneous stochasticity is the only possible mechanism for anomalous dissipation of passive or active scalars, away from walls. Here it is shown that this remains true when there are no scalar fluxes through walls. Simple examples show, on the other hand, that a distinct mechanism of non-vanishing scalar dissipation can be thin scalar boundary layers near the walls. Nevertheless, we prove for general wall-bounded flows that spontaneous stochasticity is another possible mechanism of anomalous scalar dissipation.

description: We study the time-evolution of initially trapped Bose-Einstein condensates in the Gross-Pitaevskii regime. Under a physically motivated assumption on the energy of the initial data, we show that condensation is preserved by the many-body evolution and that the dynamics of the condensate wave function can be described by the time-dependent Gross-Pitaevskii equation. With respect to previous works, we provide optimal bounds on the rate of condensation (i.e. on the number of excitations of the Bose-Einstein condensate). To reach this goal, we combine the method of \cite{LNS}, where fluctuations around the Hartree dynamics for $N$-particle initial data in the mean-field regime have been analyzed, with ideas from \cite{BDS}, where the evolution of Fock-space initial data in the Gross-Pitaevskii regime has been considered.

description: We investigate the sensitivity to weakly interacting scalar dark matter from future determination of electroweak oblique parameters in the Circular Electron-Positron Collider (CEPC) project. As illuminating examples, three dark matter models with scalar electroweak multiplets are studied. The multiplet couplings to the standard model Higgs doublet can break the mass degeneracy among the components, leading to nonzero contributions to oblique parameters. The dark matter candidate in these model is either a CP-even or CP-odd scalar, whose trilinear coupling to the Higgs boson could induce direct detection signals. For some moderate coupling values, we find that the CEPC sensitivity can be better than current direct detection experiments, exploring up to a TeV mass scale.

description: A Lagrangian fluctuation-dissipation relation has been derived in a previous work to describe the dissipation rate of advected scalars, both passive and active, in wall-bounded flows. We apply this relation here to develop a Lagrangian description of thermal dissipation in turbulent Rayleigh-Bénard convection in a right-cylindrical cell of arbitrary cross-section, with either imposed temperature difference or imposed heat-flux at the top and bottom walls. We obtain an exact relation between the steady-state thermal dissipation rate and the time for passive tracer particles released at the top or bottom wall to mix to their final uniform value near those walls. We show that an "ultimate regime" with the Nusselt-number scaling predicted by Spiegel (1971) or, with a log-correction, by Kraichnan (1962) will occur at high Rayleigh numbers, unless this near-wall mixing time is asymptotically much longer than the free-fall time, or almost the large-scale circulation time. We suggest a new criterion for an ultimate regime in terms of transition to turbulence of a thermal "mixing zone", which is much wider than the standard thermal boundary layer. Kraichnan-Spiegel scaling may, however, not hold if the intensity and volume of thermal plumes decrease sufficiently rapidly with increasing Rayleigh number. To help resolve this issue, we suggest a program to measure the near-wall mixing time, which we argue is accessible both by laboratory experiment and by numerical simulation.

 Geochus puncticollis Broun 1893b: 1367. Type locality: Moeraki Gorge.
 Type Depository. BMNH: LT, 1 PLT.
 Distribution. New Zealand (DN).
 Remarks. Broun referred to four specimens that were the basis of this species. We located two in the Broun collection (BMNH), one of which we designate as the lectotype to stabilize the epithet, with the other becoming a paralectotype. There were an additional two specimens, labeled as variants, in the Broun collection (BMNH) that we considered not to be part of the syntype series.
 This species can be distinguished from other Geochus except the G. pyriformis group by the strongly punctate elytra, which have the width of the punctures wider than the interstriae. Unlike G. pyriformis, the pronotum is oval in dorsal view and not closely appressed to the elytra.
 Type Material Examined. Lectotype, here designated (BMNH): card-mounted, “2390. [in Broun’s hand]// New Zealand. [red underline] Broun Coll. Brit. Mus. 1922-482.// Otago // Geochus puncticollis [in Broun’s hand]”. Paralectotype: 1 (BMNH), same but mounted dorsally, and “Moeraki [in Broun’s hand]”.

description: We prove a supercongruence modulo $p^3$ between the $p$th Fourier coefficient of a weight 6 modular form and a truncated ${}_6F_5$-hypergeometric series. Novel ingredients in the proof are the comparison of two rational approximations to $ζ(3)$ to produce non-trivial harmonic sum identities and the reduction of the resulting congruences between harmonic sums via a congruence between the Apéry numbers and another Apéry-like sequence.

 Geochus setiger Broun 1893a: 295. Type locality: Mount Pirongia.
 Type Depository. BMNH: LT, 7 PLT; NZAC: 1 PLT.
 Distribution. New Zealand (WO).
 Remarks. Broun stated that he had a “good series” on which to base this species, and we consider seven specimens in the Broun collection (BMNH) and one specimen in NZAC to form the syntype series. In addition, there are also a single variant in MHNP and many unlabeled Broun specimens in NZAC, which we considered not to be part of the syntype series. We designate one specimen as the lectotype to stabilize the epithet, with the seven remaining becoming paralectotypes.
 We place this species into a species group with G. similis.
 Type Material Examined. Lectotype, here designated (BMNH): card-mounted, “2889. [in Broun’s hand]// New Zealand. [red underline] Broun Coll. Brit. Mus.1922-482.//Pirongia// Geochus setiger.[in Broun’s hand]”. Paralectotypes: 7 (BMNH), same but, 4 (one mounted dorsally) with “Pirongia [printed] (2 had “setiger.

description: We propose a simple injective resolution for the Hochschild complex of the Weyl algebra. By making use of this resolution, we derive explicit expressions for nontrivial cocycles of the Weyl algebra with coefficients in twisted bimodules as well as for the smash products of the Weyl algebra and a finite group of linear symplectic transformations. A relationship with the higher-spin field theory is briefly discussed.

description: Many real-world tasks involve multiple agents with partial observability and limited communication. Learning is challenging in these settings due to local viewpoints of agents, which perceive the world as non-stationary due to concurrently-exploring teammates. Approaches that learn specialized policies for individual tasks face problems when applied to the real world: not only do agents have to learn and store distinct policies for each task, but in practice identities of tasks are often non-observable, making these approaches inapplicable. This paper formalizes and addresses the problem of multi-task multi-agent reinforcement learning under partial observability. We introduce a decentralized single-task learning approach that is robust to concurrent interactions of teammates, and present an approach for distilling single-task policies into a unified policy that performs well across multiple related tasks, without explicit provision of task identity.

 Type Depository. BMNH: LT, 3 PLT.
 Distribution. New Zealand (MC).
 Remarks. Broun stated that he had based his description on “about a dozen individuals”, four of which we located in the Broun collection (BMNH).

description: We propose a simple method based on the Aperture Antennas Theory to understand in a simple fashion limitations of OAM antennas in far-field links. Additional insight is also given by analyzing the properties of the operators relating source and far-field distributions for a given order of the vortex. The outcomes fully agree with the results recently achieved by Edfors, Craeye, and co-authors, and emphasize some additional draw-back. The "degrees of freedom" of the fields associated to the different orders of the vortices are also discussed.

UNDERSTANDING VIDEO GAME DEVELOPER INTENTION VERSUS OUTCOME AS IT PERTAINS TO AUDIENCE EXPERIENCE WITH GAME NARRATIVE

description: This paper is a qualitative study that utilizes game players to learn more about the impact of game narrative, and to use this information to understand more of its role in the production of
 games. Initial research into the topic revealed that many competing interests drive game production, but that if narrative was “down-prioritized” in production, a game was more likely to suffer compounding issues that could result in a poor end-product and launch. This nets monetary consequences for a studio, but also severely impacts the team of developers. As the game industry already faces widespread issues with crunch, long work hours over long periods of time, any additional strain on production exacerbates existing issues. Game production documentation is often held privately as the trade secrets of a given studio, so the most feasible way to address these questions is to seek a successful game with amble published documentation and compare those resources to the experiences players themselves have with the title. The Legend of Zelda: Breath of the Wild was the game chosen.
 A sample of 18 students from Purdue University completed an initial interest survey and provided demographic information. Of those who played games regularly, 4 participants were randomly selected to move forward with an audio and video recorded gameplay session that utilized a think-aloud protocol to capture moment-to-moment experience, and then an audio recorded interview about their experiences. These methods were employed to generate transcripts of their thoughts and experiences where the researcher conducted a thematic analysis of the content. Fifteen codes were synthesized from these transcripts and found that through the context of narrative, participants expressed that gameplay, aesthetics, and critical paths in a game facilitated their experiences with narrative. Participants approached the game and spoke about narrative in a variety of ways during the game session, but all came away with similar conclusions when interviewed. This suggests that game elements that convey narrative are highly effective and opens questions into how changes to those elements can sway interpretation and if that can be controlled for. Further, studying the patterns between these elements and determining what creates the most meaning for players could open new avenues for efficient game design.

description: We use the correspondence between three-dimensional asymptotically flat spacetimes and two-dimensional contracted conformal field theories (CCFTs) to derive the stress tensor correlators of CCFT$_2$. On the gravity side we use the metric formulation instead of the Chern-Simons formulation of three-dimensional gravity. This method can also be used for four-dimensional case where there is no Chern-Simons formulation for the bulk theory.

description: We report the experimental realization of Dirac semimetal state in NdSb, a material with antiferromagnetic ground state. The occurrence of topological semimetal state has been well supported by our band structure calculations and the experimental observation of chiral anomaly induced negative magnetoresistance. A field-induced Fermi surface reconstruction is observed, in response to the change of spin polarization. The observation of topological semimetal state in a magnetic material provides an opportunity to investigate the magneto-topological phenomena.
Two-dimensional Fermi gases near a p-wave resonance: effect of quantum fluctuations

description: We study the stability of p-wave superfluidity against quantum fluctuations in two-dimensional Fermi gases near a p-wave Feshbach resonance . An analysis is carried out in the limit when the interchannel coupling is strong. By investigating the effective potential for the pairing field via the standard loop expansion, we show that a homogeneous p-wave pairing state becomes unstable when two-loop quantum fluctuations are taken into account. This is in contrast to the previously predicted $p + ip$ supefluid in the weak-coupling limit [V. Gurarie et al., Phys. Rev. Lett. 94, 230403 (2005)]. It implies a possible onset of instability at certain intermediate interchannel coupling strength. Alternatively, the instability can also be driven by lowering the particle density. We also discuss the validity of our analysis.
