description: Despite the tremendous progress of quantum cryptography, efficient quantum communication over long distances (>1000km) remains an outstanding challenge due to fiber attenuation and operation errors accumulated over the entire communication distance. Quantum repeaters, as a promising approach, can overcome both photon loss and operation errors, and hence significantly speedup the communication rate. Depending on the methods used to correct loss and operation errors, all the proposed QR schemes can be classified into three categories (generations). Here we present the first systematic comparison of three generations of quantum repeaters by evaluating the cost of both temporal and physical resources, and identify the optimized quantum repeater architecture for a given set of experimental parameters. Our work provides a roadmap for the experimental realizations of highly efficient quantum networks over transcontinental distances.

description: We study the dynamics of quantum coherence under Unruh thermal noise and seek under which condition the coherence can be frozen in a relativistic setting. We find that the frozen condition is either (i) the initial state is prepared as a incoherence state, or (ii) the detectors have no interaction with the external field. That is to say, the decoherence of detectors' quantum state is irreversible under the influence of thermal noise induced by Unruh radiation. It is shown that quantum coherence approaches zero only in the limit of an infinite acceleration, while quantum entanglement could reduce to zero for a finite acceleration. It is also demonstrated that the robustness of quantum coherence is better than entanglement under the influence of the atom-field interaction for an extremely large acceleration. Therefore, quantum coherence is more robust than entanglement in an accelerating system and the coherence type quantum resources are more accessible for relativistic quantum information processing tasks.

description: We construct an analog computer based on light interference to encode the hyperbolic function f(ζ) = 1/ζ into a sequence of skewed curlicue functions. The resulting interferogram when scaled appropriately allows us to find the prime number decompositions of integers. We implement this idea exploiting polychromatic optical interference in a multipath interferometer and factor seven-digit numbers. We give an estimate for the largest number that can be factored by this scheme.

description: The web survey was carried out in 2008, targeting all prosecutors and judges in office in Finland and Sweden. The forms of improper influence addressed in the questionnaire were harassment, threats, violence, vandalism and corruption. The reference period applied was the preceding 18 months. The survey was carried out simultaneously in Finland and in Sweden using an identical questionnaire. Judges and prosecutors have experience of all of the listed forms of improper influences. However, the dominant forms of influence are harassment and threats. Victimisation occurred primarily at the workplace, and only rarely in the leisure time of the respondents. Most of the perpetrators were individuals who were not connected with criminal organisations. This is the case in particular when the victim was a judge. Occasionally, however, organised crime representatives were also observed to be involved. This was true for prosecutors in particular. Swedish prosecutors were harassed and threatened by organised crime representatives significantly more often than Finnish prosecutors. It was unusual that family members of the civil servants concerned were victimised, but also some such instances were reported, some of them quite serious. Again, such incidents were more likely in Sweden than in Finland. According to the respondents, the employer organisations of the respondents had not done very much to prevent such incidents or to protect their employees from improper influences. The respondents were also of the opinion that much more should be done about the problem. The respondents had many suggestions for improvements, some of them quite sophisticated. These included, inter alia, ideas concerning the way their work was organised, the protection of personal data, access control, and the physical design of the offices and courtrooms. Overall, the responses demonstrate that the persons involved should be consulted carefully when planning and implementing new measures to prevent improper influences and to minimize their impact.

Subjects: subject: Teaching--India

description: The practice of teaching students topics well in advance of their grade level has become popular in Telangana State, India. Most state private schools teach their students one to two grades in advance to their enrolled grade level. This can be seen from Grades 6 through 9. During my 18 year teaching career, I was involved in this teaching practice for one year at a private school, in Hyderabad, the capital city of Telangana State. The purpose of this paper was to analyze the arguments which support and oppose this practice by surveying the school’s Grade 8 and 9 students, their parents, teachers, and principal. The challenges and benefits of teaching advanced concept curriculum were examined in this study.

description: We demonstrate theoretically that charge transport across a Josephson junction, voltage-biased through a resistive environment, produces antibunched photons. We develop a continuous-mode description of the emitted radiation field in a semi-infinite transmission line terminated by the Josephson junction. Within a perturbative treatment in powers of the tunneling coupling across the Josephson junction, we capture effects originating in charging dynamics of consecutively tunneling Cooper pairs. We find that within a feasible experimental setup the Coulomb blockade provided by high zero-frequency impedance can be used to create antibunched photons at a very high rate and in a very versatile frequency window ranging from a few GHz to a THz.

description: We analyse the effect of intrinsic fluctuations on the properties of bistable stochastic systems with time scale separation operating under1 quasi-steady state conditions. We first formulate a stochastic generalisation of the quasi-steady state approximation based on the semi-classical approximation of the partial differential equation for the generating function associated with the Chemical Master Equation. Such approximation proceeds by optimising an action functional whose associated set of Euler-Lagrange (Hamilton) equations provide the most likely fluctuation path. We show that, under appropriate conditions granting time scale separation, the Hamiltonian can be re-scaled so that the set of Hamilton equations splits up into slow and fast variables, whereby the quasi-steady state approximation can be applied. We analyse two particular examples of systems whose mean-field limit has been shown to exhibit bi-stability: an enzyme-catalysed system of two mutually-inhibitory proteins and a gene regulatory circuit with self-activation. Our theory establishes that the number of molecules of the conserved species are order parameters whose variation regulates bistable behaviour in the associated systems beyond the predictions of the mean-field theory. This prediction is fully confirmed by direct numerical simulations using the stochastic simulation algorithm. This result allows us to propose strategies whereby, by varying the number of molecules of the three conserved chemical species, cell properties associated to bistable behaviour (phenotype, cell-cycle status, etc.) can be controlled.

description: We present a model for the $γ^\ast N \to N^\ast$ helicity amplitudes, where $N$ is the nucleon and $N^\ast$ is a negative parity nucleon excitation, member of the $SU(6)$-multiplet $[70,1^-]$. The model combines the results from the single quark transition model for the helicity amplitudes with the results of the covariant spectator quark model for the $γ^\ast N \to N^\ast(1535)$ and $γ^\ast N \to N^\ast(1520)$ transitions. With the knowledge of the amplitudes $A_{1/2}$ and $A_{3/2}$ for those transitions we calculate three independent coefficients defined by the single quark transition model and make predictions for the helicity amplitudes associated with the $γ^\ast N \to N^\ast(1650)$, $γ^\ast N \to N^\ast(1700)$, $γ^\ast N \to Δ(1620)$, and $γ^\ast N \to Δ(1700)$ transitions. In order to facilitate the comparison with future experimental data at high $Q^2$, we provide also simple parametrizations for the amplitudes, compatible with the expected falloff at high $Q^2$.

description: The combined effect of SFP and the non standard neutrino interaction (NSI) on the survival probability of solar electron neutrinos (assumed to be Dirac particles) is examined for various values of $ε_{11}$, $ε_{12}$ and $μB$. It is found that the neutrino survival probability curves affected by SFP and NSI effects individually for some values of the parameters ($ε_{11}$, $ε_{12}$ and $μB$) get close to the standard MSW curve when both effects are combined. Therefore, the combined effect of SFP and NSI needs to be taken into account when the solar electron neutrino data obtained by low energy solar neutrino experiments is investigated.

description: We present the general theory of a quantum heat machine based on an $N$-level system (working medium) whose $N-1$ excited levels are degenerate, a prerequisite for steady-state interlevel coherence. Our goal is to find out: To what extent is coherence in the working medium an asset for heat machines? The performance bounds of such a machine are common to (reciprocating) cycles that consist of consecutive strokes and continuous cycles wherein the periodically driven system is constantly coupled to cold and hot heat baths. Intriguingly, we find that the machine's performance strongly depends on the relative orientations of the transition-dipole vectors in the system. Perfectly aligned (parallel) transition dipoles allow for steady-state coherence effects, but also give rise to dark states, which hinder steady-state thermalization and thus reduce the machine's performance. Similar thermodynamic properties hold for $N$ two-level atoms conforming to the Dicke model. We conclude that level degeneracy, but not necessarily coherence, is a thermodynamic resource, equally enhancing the heat currents and the power output of the heat machine. By contrast, the efficiency remains unaltered by this degeneracy and adheres to the Carnot bound.

description: Doppler tomography is a well-known method in astrophysics to image the accretion flow, often in the shape of thin discs, in compact binary stars. As accretion discs rotate, all emitted line radiation is Doppler-shifted. In fast-ion D-alpha (FIDA) spectroscopy measurements in magnetically confined plasma, the D-alpha-photons are likewise Doppler-shifted ultimately due to gyration of the fast ions. In either case, spectra of Doppler-shifted line emission are sensitive to the velocity distribution of the emitters. Astrophysical Doppler tomography has lead to images of accretion discs of binaries revealing bright spots, spiral structures, and flow patterns. Fusion plasma Doppler tomography has lead to an image of the fast-ion velocity distribution function in the tokamak ASDEX Upgrade. This image matched numerical simulations very well. Here we discuss achievements of the Doppler tomography approach, its promise and limits, analogies and differences in astrophysical and fusion plasma Doppler tomography, and what can be learned by comparison of these applications.

We must now plan not so much for an urban "environment" as for an urban ecology, and we must make this kind of planning "human nature." Tyler focuses attention on innovative demonstration projects that embody the necessary type of "how" in response to her primary interest in "why."

We use a generalized Schrödinger picture in which the analogs of the Schrödinger operators of the particle are independent of both the time and the space coordinates in different representations. The spacetime independent operators of the particle induce the Lie algebra of Killing vector fields of the $AdS_3$ spacetime. In this picture, we have a metamorphosis of the Heisenberg's uncertainty relations.

description: This review sets out to (i) identify and synthesise the evidence base of education programmes in conflict-affected areas of Nigeria in order to generate a rigorous understanding of the circumstances under which education is delivered; and (ii) identify evidence gaps concerning access, quality and continuity of education, and the interventions that aim to improve education outcomes. The review was conducted as part of the Education Research in Conflict and Protracted Crisis (ERICC) programme. The literature review drew on peer-reviewed academic papers and programme reports, which were categorised according to the ERICC conceptual and research framework according to the research questions and programmes they addressed. The findings show that, although there is promising evidence of interventions which can improve academic outcomes of out-of-school children in some areas, particularly around teaching and learning, there remain significant evidence gaps related to: (i) the state of policies, budgets and data systems; (ii) the state of coherence in the education system and the factors that enable or constrain coherence; (iii) policy-level interventions which can alignment, accountability and adaptability of the education system; (iv) interventions which can improve access, quality and continuity of children's education in conflict affected areas in cost-effective ways; (v) the status of children’s academic learning, social emotional development, mental health and well-being, and achievement and equity for different subgroups; and (vi) system strengthening education interventions which can improve children's achievement and equity in cost-effective ways. Findings were used to inform the generation of to develop the ERICC Nigeria programme through consultation with key government and non-government stakeholders.

description: On the basis of the quantum Zeno effect it has been recently shown [D. K. Burgarth et al., Nat. Commun. 5, 5173 (2014)] that a strong amplitude damping process applied locally on a part of a quantum system can have a beneficial effect on the dynamics of the remaining part of the system. Quantum operations that cannot be implemented without the dissipation become achievable by the action of the strong dissipative process. Here we generalize this idea by identifying decoherence-free subspaces (DFS's) as the subspaces in which the dynamics becomes more complex. Applying methods from quantum control theory we characterize the set of reachable operations within the DFS's. We provide three examples which become fully controllable within the DFS's while the control over the original Hilbert space in the absence of dissipation is trivial. In particular, we show that the (classical) Ising Hamiltonian is turned into a Heisenberg Hamiltonian by strong collective decoherence, which provides universal quantum computation within the DFS's. Moreover we perform numerical gate optimization to study how the process fidelity scales with the noise strength. As a byproduct a subsystem fidelity which can be applied in other optimization problems for open quantum systems is developed.

description: Most HPC systems are clusters of shared memory nodes. To use such systems efficiently both memory consumption and communication time has to be optimized. Therefore, hybrid programming may combine the distributed memory parallelization on the node interconnect (e.g., with MPI) with the shared memory parallelization inside of each node (e.g., with OpenMP or MPI-3.0 shared memory). This course analyzes the strengths and weaknesses of several parallel programming models on clusters of SMP nodes. Multi-socket-multi-core systems in highly parallel environments are given special consideration. MPI-3.0 has introduced a new shared memory programming interface, which can be combined with inter-node MPI communication. It can be used for direct neighbor accesses similar to OpenMP or for direct halo copies, and enables new hybrid programming models. These models are compared with various hybrid MPI+OpenMP approaches and pure MPI. Numerous case studies and micro-benchmarks demonstrate the performance-related aspects of hybrid programming. Hands-on sessions are included on all days. Tools for hybrid programming such as thread/process placement support and performance analysis are presented in a "how-to" section. This course provides scientific training in Computational Science and, in addition, the scientific exchange of the participants among themselves. Content Levels: Beginners = 0:00h (0%) + Intermediate = 1:30h (10%) + Advanced = 13:30h (90%) This course is a PRACE training event. It is organized by the VSC Research Center, TU Wien, in cooperation with HLRS and RRZE.

description: We consider the problem of estimating the state of a noisy linear dynamical system when an unknown subset of sensors is arbitrarily corrupted by an adversary. We propose a secure state estimation algorithm, and derive (optimal) bounds on the achievable state estimation error given an upper bound on the number of attacked sensors. The proposed state estimator involves Kalman filters operating over subsets of sensors to search for a sensor subset which is reliable for state estimation. To further improve the subset search time, we propose Satisfiability Modulo Theory based techniques to exploit the combinatorial nature of searching over sensor subsets. Finally, as a result of independent interest, we give a coding theoretic view of attack detection and state estimation against sensor attacks in a noiseless dynamical system.

Supporting transgender students in SD#79: finding belonging in a school community
Creators: name: Donnelly, Alison
Publisher: name: Vancouver Island University - Royal Roads University
Year: 2018
Subjects: subject: Transgender students

description: Youth that identify as transgender or gender variant are reported to have a harder time finding belonging in a school community. This study explored the experiences of these youth in several schools on Vancouver Island. Qualitative data collection was done through anonymous surveys, one-on-one interviews with youth, as well as through the collection of student-created art. Data analysis revealed four main areas where schools and school districts could further support transgender and gender variant youth: the creating of gender-neutral change rooms/locker rooms, gender-neutral washrooms, teachers using the students chosen pronoun and chosen name, creating an ideal gender-neutral place as a place for transgender and gender variant youth to have a safe space to simply “be”. This study suggests that creating a sense of belonging where transgender and gender variant youth can feel accepted and welcomed is an important factor in these students staying in school, as well as creating and maintaining student wellbeing.

description: The resistance of a metal in a magnetic field can be very illuminating about its ground state. Some famous examples include the integer and fractional quantum Hall effects\cite{Klitzing-QHE,Tsui-FQHE}, Shubnikov-de Haas oscillations\cite{SdH}, and weak localization\cite{Lee-WL} \emph{et al}. In non-interacting metals the resistance typically increases upon the application of a magnetic field\cite{Pippard-MR}. In contrast, in some special circumstances metals, with anisotropic Fermi surfaces\cite{Kikugawa-PdCoO2LMR} or a so-called Weyl semimetal for instance\cite{Nielsen-ABJ,Son-ChirAnom}, may have negative magnetoresistance. Here we show that semimetallic TaAs$_2$ possesses a gigantic negative magnetoresistance ($-$98\% in a field of 3 T at low temperatures), with an unknown mechanism. Density functional calculations illustrate that TaAs$_2$ is a new topological semimetal [$\mathbb{Z}_2$ invariant (0;111)] without a Dirac dispersion. This demonstrates that the presence of negative magnetoresistance in non-magnetic semimetals cannot be uniquely attributed to the Adler-Bell-Jackiw anomaly of bulk Dirac/Weyl fermions. Our results also imply that the OsGe$_2$-type monoclinic dipnictides are likely a material basis where unconventional topological semimetals may be found.

Active school transportation: counting steps toward a healthy future

Subjects: subject: Exercise

description: One of the most pressing concerns affecting Canadian youth today is their failure to obtain sufficient levels of physical activity. Canadian and World Health Organization guidelines stipulate that to derive health benefits, children and youth must engage in at least 60 minutes per day of moderate-to-vigorous physical activity (Canadian Society for Exercise Physiology, 2016; WHO, 2010). Only 9% of boys and 4% of girls in Canada meet this target (Colley et al., 2011). The routine weekday journey to and from school provides students an opportunity to maximize the span of time they spend exercising. According to recent systematic reviews, utilizing self-propelled modes of travel for the journey between home and school such as walking, cycling, or skateboarding is associated with increased levels of physical activity among youth (Faulkner, Buliung, Flora, & Fusco, 2009; Larouche, Saunders, Faulkner, Colley, & Tremblay, 2014). Over the course of four school days, the present study tracked pedometer-measured steps per day of two active and two non-active secondary school commuters in an effort to quantify their difference in physical activity levels. Daily steps comparisons were made between students who engaged in active school transportation versus students who did not. Findings revealed that on average the active travellers accumulated 585 more daily steps than those using passive school transportation (8471 vs. 7886 steps). This represented a mean difference of 7.15% in steps per day between the active and passive travellers.

description: We study wavefunctions on D$7$-branes with magnetic fluxes in the conifold. Since some supersymmetric embeddings of D-branes on the $AdS_5\times T^{1,1}$ geometry are known, we consider one of the embeddings, especially the spacetime filling D$7$-branes in which (a part of) the standard model is expected to be realized. The explicit form of induced metric on the D$7$-branes allows us to solve the Laplace and Dirac equations to evaluate matter wavefunctions in extra dimensions analytically. We find that the zero-mode wavefunctions can be localized depending on the configuration of magnetic fluxes on D$7$-branes, and show some phenomenological aspects.

Subjects: subject: Education--Ghana

description: This research explores fully, cultural mind-set, as the main factor that underlies the problem of girls’ education in Ghana, rather than poverty. This research highlights and analyses the cultural aspects of Ghanaian society that impede girls to enter schooling and break out of the cycle of poverty. In the first part, this study focuses on feminist theories from “developing” countries as a theoretical framework. The second part of this research analyses the traditions and customs against girls ‘education, concluding with some recommendations.
