description: Targeted observations of possible exomoon host systems will remain difficult to obtain and time-consuming to analyze in the foreseeable future. As such, time-domain surveys such as Kepler, K2 and TESS will continue to play a critical role as the first step in identifying candidate exomoon systems, which may then be followed-up with premier ground- or space-based telescopes. In this work, we train an ensemble of convolutional neural networks (CNNs) to identify candidate exomoon signals in single-transit events observed by Kepler. Our training set consists of ${\sim}$27,000 examples of synthetic, planet-only and planet+moon single transits, injected into Kepler light curves. We achieve up to 88\% classification accuracy with individual CNN architectures and 97\% precision in identifying the moons in the validation set when the CNN ensemble is in total agreement. We then apply the CNN ensemble to light curves from 1880 Kepler Objects of Interest with periods $>10$ days ($\sim$57,000 individual transits), and further test the accuracy of the CNN classifier by injecting planet transits into each light curve, thus quantifying the extent to which residual stellar activity may result in false positive classifications. We find a small fraction of these transits contain moon-like signals, though we caution against strong inferences of the exomoon occurrence rate from this result. We conclude by discussing some ongoing challenges to utilizing neural networks for the exomoon search.

description: Mifepristone, also known by its drug development name RU486, is an anti-progestin that is part of the gold standard regimen of medication abortion. This medication is taken orally to induce an abortion through 70 days after the first day of the pregnant person’s last menstrual period. When mifepristone is used in conjunction with misoprostol, a prostaglandin analog that induces uterine contractions and causes cervical softening, the regimen results in a complete abortion about 98% of the time. France first registered mifepristone for use as an early abortifacient in 1988. Mifepristone has subsequently been introduced in more than 60 countries and used by over 40 million women worldwide. The promise of mifepristone to expand access to abortion care stems from the fact that it can be safely provided by a variety of clinicians, including family doctors and nurse practitioners, in a wider variety of settings than instrumentation abortion procedures. In addition, the regimen is safe, effective, cost-effective, and highly acceptable to patients. Canada and Australia are two countries that have recently made mifepristone available after drawn-out drug approval processes. In Canada, mifepristone was registered in 2015 and became available in 2017; in Australia, mifepristone was approved for commercial import in 2012. This thesis uses qualitative methods to explore how the introduction of mifepristone has impacted the service delivery landscape of abortion care in Canada and Australia, with a specific focus on patient experiences. In addition, this thesis examines how different regulatory settings and barriers condition access to abortion care and aims to generate policy-relevant insights for improving access to medication abortion.

description: La notion de posture évaluative désigne un ensemble original et spécifique de manières d’appréhender et de réagir à l’action publique. Cette posture est particulièrement celle des professionnel·les engagées dans une démarche d’évaluation ; mais elle ne s’y limite pas, et peut s’appliquer dans de nombreuses autres situations : par exemple, dans la conception des politiques, leur gouvernance, l’organisation et la gestion de projet, la participation citoyenne, la diffusion des connaissances, etc. Elle n’est pas non plus l’apanage des évaluateurs/rices : de multiples activités font appel à une posture évaluative, et savoir prendre une posture évaluative fait partie des compétences clés que devraient développer les personnes travaillant avec l’action publique. Nous résumons ici certains des traits dominants de cette posture évaluative sous l’acronyme ROSACE : une posture Réflexive, Orientée conséquences, Soucieuse d’utilité, Sceptique, Systématique, Attentive aux valeurs, Curieuse et Empirique. Ces traits sont interconnectés et se recoupent parfois.

description: We present a new algorithm for deploying passenger robots in marsupial robot systems. A marsupial robot system consists of a carrier robot (e.g., a ground vehicle), which is highly capable and has a long mission duration, and at least one passenger robot (e.g., a short-duration aerial vehicle) transported by the carrier. We optimize the performance of passenger robot deployment by proposing an algorithm that reasons over uncertainty by exploiting information about the prior probability distribution of features of interest in the environment. Our algorithm is formulated as a solution to a sequential stochastic assignment problem (SSAP). The key feature of the algorithm is a recurrence relationship that defines a set of observation thresholds that are used to decide when to deploy passenger robots. Our algorithm computes the optimal policy in $O(NR)$ time, where $N$ is the number of deployment decision points and $R$ is the number of passenger robots to be deployed. We conducted drone deployment exploration experiments on real-world data from the DARPA Subterranean challenge to test the SSAP algorithm. Our results show that our deployment algorithm outperforms other competing algorithms, such as the classic secretary approach and baseline partitioning methods, and is comparable to an offline oracle algorithm.
Self-consistently renormailzed spin-wave theory of layered ferromagnets on honeycomb lattice

description: We develop a self-consistently renormalized spin-wave theory, within a mean-field approximation, for the two-dimensional Heisenberg ferromagnet with perpendicular easy-axis anisotropy on the honeycomb lattice, as well as its few-layer and bulk extensions. In this method, the magnetization dependence on temperature is found as the solution of the self-consistency equation. Furthermore, we account for the physical difference of surface and bulk layers by treating the layers as separate sublattices. Thus, the method can be readily generalized to study various magnetic phenomena in a broad range of systems, including those comprising magnetically inequivalent sublattices. Using our theory, we calculate the temperature-dependent magnetization for two chromium-based layered van der Waals insulating magnets, Cr$_2$Ge$_2$Te$_6$ and CrI$_3$, employing various sets of Heisenberg exchange and single-ion anisotropy values reported for these materials in the existing literature. As expected, we observe a strong dimensionality effect where the ordering temperature is reduced and its sensitivity on the anisotropy is enhanced with the decrease of dimensionality.

description: Marsupial robot teams consist of carrier robots that transport and deploy multiple passenger robots, such as a team of ground robots that carry and deploy multiple aerial robots, to rapidly explore complex environments. We specifically address the problem of planning the deployment times and locations of the carrier robots to best meet the objectives of a mission while reasoning over uncertain future observations and rewards. While prior work proposed optimal, polynomial-time solutions to single-carrier robot systems, the multiple-carrier robot deployment problem is fundamentally harder as it requires addressing conflicts and dependencies between deployments of multiple passenger robots. We propose a centralized heuristic search algorithm for the multiple-carrier robot deployment problem that combines Monte Carlo Tree Search with a dynamic programming-based solution to the Sequential Stochastic Assignment Problem as a rollout action-selection policy. Our results with both procedurally-generated data and data drawn from the DARPA Subterranean Challenge Urban Circuit show the viability of our approach and substantial exploration performance improvements over alternative algorithms.

description: The purpose of this study is to discuss the effectiveness of local industrial policies and show that effective industrial policies contribute to both the evolution and development of the cluster in the Chinese context, based on comparative advantages and market failures. We adopted a single case study method and conducted interviews with 30 stakeholders in the tea clusters; a documentary investigation was also used as a supplement. This case study finds that local industrial policies have played an important role when market failures occur in the development of agricultural clusters. The local government implemented a series of industrial policies to promote the progress of the tea industry at various stages of development. The case study further demonstrates what can be considered as an effective industrial policy in the dynamic process of agricultural development. This case also provides empirical evidence for local governments to remain sensitive to challenges and to develop timely industrial policies when an industrial cluster is faced with either opportunities or crises. Therefore, it has implications for local governments that need to improve agriculture in undeveloped regions.

Publisher: name: arXiv
Year: 2008
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We calculate medium photons due to Compton and annihilation processes in an anisotropic media. The effects of time-dependent momentum-space anisotropy of {\em Quark-Gluon-Plasma} (QGP) on the medium photon production are discussed. Such an anisotropy can results from the initial rapid longitudinal expansion of the matter, created in relativistic heavy ion collisions. A phenomenological model for the time-dependence of the parton hard momentum scale, $p_{hard}(τ)$, and anisotropy parameter, $ξ(τ)$, has been used to describe the plasma space-time evolution. We find significant dependency of photon yield on the isotropization time ($τ_{iso}$). It is shown that the introduction of early time momentum-space anisotropy can enhance the photon production by a factor of $10 (1.5)$ (in the central rapidity region) for {\em free streaming} ({\em collisionally-broadened}) {\em interpolating} model if we assume fixed initial condition. On the other hand, enforcing the fixed final multiplicity significantly reduces the enhancement of medium photon production.

A systematic study of muon capture

Publisher: name: University of British Columbia
Year: 2010

description: Negative mucn lifetimes have been measured in 48 elements including four pairs of separated isotope targets (⁶Li, ⁷Li, ¹⁰B, ¹¹B, ¹²C, ¹³C, ¹⁶O, ¹⁸O) . The experimental set-up and electronics logic were checked against the positive muon lifetime, wiich was measured to be 2197,0±0.7 ns, in good agreement with the accepted value of 2197.120±0.077 ns. Muons were produced by the backward decay of pions which were provided by the M20 beam channel at TRIUMF. The negative muon lifetimes were measured for all light elements except H and He. An improved accuracy has been achieved in Be, N, 0, F, Na, Cl, and K, and new measurements were performed for ¹³C, ¹⁸O, Dy and Er. Strong isotope effects were observed in Li, B, and O, but there was no isotope effect in C. Our results in ⁶Li and ⁷Li were in good agreement with the predicted values by Lodder and Jonker. Our measurements confirm that the even-odd effect in heavy nuclei is not strong and the increase of the odd-Z capture rates is smaller than that expected from the quenching of the Cabibbo angle in large magnetic fields. The negative muon beam was also stopped in 23 metallic oxides in order to measure the atomic capture ratios. The number of muons captured by each element was deduced by lifetime analysis. Our result reproduced the periodic dependence and agreed well with earlier X-ray measurements. The results however are of higher accuracy and are liable to very different systematic errors, which gives added confidence to the overall situation.

description: Recent studies have revealed much of the mathematical structure of the static correlation functions of the XXZ chain. Here we use the results of those studies in order to work out explicit examples of short-distance correlation functions in the infinite chain. We compute two-point functions ranging over 2, 3 and 4 lattice sites as functions of the temperature and the magnetic field for various anisotropies in the massless regime $- 1 < Δ< 1$. It turns out that the new formulae are numerically efficient and allow us to obtain the correlations functions over the full parameter range with arbitrary precision.

Cluster tilting for higher Auslander algebras

Publisher: name: arXiv
Year: 2008
Subjects: subject: Representation Theory (math.RT)
subject: FOS: Mathematics

description: The concept of cluster tilting gives a higher analogue of classical Auslander correspondence between representation-finite algebras and Auslander algebras. The $n$-Auslander-Reiten translation functor $τ_n$ plays an important role in the study of $n$-cluster tilting subcategories. We study the category $\MM_n$ of preinjective-like modules obtained by applying $τ_n$ to injective modules repeatedly. We call a finite dimensional algebra $Λ$ \emph{$n$-complete} if $\MM_n=\add M$ for an $n$-cluster tilting object $M$. Our main result asserts that the endomorphism algebra $\End_Λ(M)$ is $(n+1)$-complete. This gives an inductive construction of $n$-complete algebras. For example, any representation-finite hereditary algebra $Λ^{(1)}$ is 1-complete. Hence the Auslander algebra $Λ^{(2)}$ of $Λ^{(1)}$ is 2-complete. Moreover, for any $n\ge1$, we have an $n$-complete algebra $Λ^{(n)}$ which has an $n$-cluster tilting object $M^{(n)}$ such that $Λ^{(n+1)}=\End_{Λ^{(n)}}(M^{(n)})$. We give the presentation of $Λ^{(n)}$ by a quiver with relations. We apply our results to construct $n$-cluster tilting subcategories of derived categories of $n$-complete algebras.

description: Bioorthogonal chemistry involves the development of chemical reactions that can be used to monitor, quantify and manipulate the roles of biological molecules in their native environments. Although there is a continuous demand to develop reactions with fast kinetics, developing reactions that make use of small “mini tag” functional groups are necessary to avoid perturbing function and to cross cellular membranes. Nitrones are small functional groups that have been shown to be excellent alternative 1,3-dipoles to azides in strain-promoted alkyne-nitrone cycloaddition reactions (SPANC). To further expand on the use of nitrones as reacting partners with other dipolarophiles, the kinetics of a variety of acyclic and cyclic nitrones were evaluated with strained- trans-cyclooctene. The reactions of acyclic nitrones were conducted under pseudo first-order conditions using UV-visible spectroscopy. By changing the α-aryl- substituent on acyclic nitrones, a linear free energy relationship shows increased reactivity with electron deficient nitrones. Second order rate constants of cyclic nitrones were found to be similar to those of acyclic nitrones, achieving 95% conversion in less than 20 minutes. Using unnatural D-amino acids tagged with nitrones, and s-TCO-Alexa488, labelling of the bacterial peptidoglycan layer was demonstrated. These new findings expand the bioorthogonal toolbox and allow for TCO reagents to be used in bioorthogonal applications beyond tetrazine ligations. The optimization of click reactions for biological settings has substantially increased the versatility of these reactions for applications beyond biological labelling such as polymer synthesis. A strained cyclootadiyne, namely sym-dibenzo- 1,5-cyclooctadiene-3,7-diyne (diyne) is a benzylated- strained di-alkyne primed for strained- double-click chemistry for conjugation of molecules containing 1,3-dipoles. The second order rate constants for the consecutive additions of a variety of nitrones onto diyne were established via pseudo first-order kinetics by UV-visible spectroscopy. The kinetics of the double addition of acyclic nitrones onto this diyne show that the second addition occurs with second order rate constants more than 2-fold greater, and rates of the second addition can be increased by using electron deficient nitrones. Mechanistic investigation failed to observe the mono-intermediate, and experiments are outlined for future investigation of this phenomenon. Using the kinetic analysis results, di-nitrone monomers containing cyclic and diaryl-nitrones were designed for use in polymer applications. Based on the reports herein, we anticipate the application of this new double-SPANC reaction for peptide cross-linking, polymer synthesis and conjugation of biological molecules.

We focus our analysis on the question: Do the different storytellers in the text exhibit distinct personalities? To answer this question, we curate and release a dataset based on the authoritative edition of the text. We use supervised classification methods to predict storytellers based on the stories they tell, confirming the difficulty of the task, and demonstrate that topic modeling can extract thematic storyteller "profiles."

description: Agia Lake, an artificial lake that has evolved into a natural wetland and is now part of the Natura 2000 network, hosts rich flora and fauna.
On its shores stands the ruined Manos Mill, a water-powered flour mill built in 1912, which maintains a dialogue of memory with the landscape.
At the entrance of the lake park lies the old Moisidis juice factory, an industrial shell from the 1950s, a remnant of a different productive era in the region.
This diploma project explores the connection between these two abandoned structures, redefining their use and creating a route that highlights the natural landscape. The mill is transformed into an information center for the lake’s ecosystem, as well as a small research facility for its study and protection. The old factory complements this function by providing temporary accommodation for researchers. The two structures are unified through gentle landscape interventions and connections with lightweight constructions that take advantage of the area’s natural features, serving alternately as pathways and resting points for observing and experiencing the landscape.

description: Based on the modeling of the central emission-line width measured over sub-arcsecond apertures with the Hubble Space Telescope, we present stringent upper bounds on the mass of the central supermassive black hole, MBH, for a sample of 105 nearby galaxies (D<100Mpc) spanning a wide range of Hubble types (E-Sc) and values of the central stellar velocity dispersion, sigma (58-419km/s). For the vast majority of the objects the derived MBH upper limits run parallel and above the well-known MBH-sigma relation independently of the galaxy distance, suggesting that our nebular line-width measurements trace rather well the nuclear gravitational potential. For values of sigma between 90 and 220km/s the 68% of our upper limits falls immediately above the MBH-sigma relation without exceeding the expected MBH values by more than a factor 4.1. No systematic trends or offsets are observed in this sigma range as a function of the galaxy Hubble type or with respect to the presence of a bar. For 6 of our 12 MBH upper limits with sigma<90km/s our line-width measurements are more sensitive to the stellar contribution to the gravitational potential, either due to the presence of a nuclear stellar cluster or because of a greater distance compared to the other galaxies at the low-sigma end of the MBH-sigma relation. Conversely, our MBH upper bounds appear to lie closer to the expected MBH in the most massive elliptical galaxies with values of sigma above 220km/s. Such a flattening of the MBH-sigma relation at its high-sigma end would appear consistent with a coevolution of supermassive black holes and galaxies driven by dry mergers, although better and more consistent measurements for sigma and K-band luminosity are needed for these kind of objects before systematic effects can be ruled out.

description: The formation and growth of galaxy disks over cosmic time is crucial to our understanding of galaxy formation. Despite steady improvements in the size and quality of disk samples over the last decade, many aspects of galaxy disk evolution remain unclear. Using two square degrees of deep, wide-field i'-band imaging from the Canada-France-Hawaii Telescope Legacy Survey, we compute size functions for 6000 disks from z=0.2 to z=1 and explore luminosity and number density evolution scenarios with an emphasis on the importance of selection effects on the interpretation of the data. We also compute the size function of a very large sample of disks from the Sloan Digital Sky Survey to use as a local (z ~ 0.1) comparison. CFHTLS size functions computed with the same fixed luminosity-size selection window at all redshifts exhibit evolution that appears to be best modelled by a pure number density evolution. The z = 0.3 size function is an excellent match to the z = 0.9 one if disks at the highest redshift are a factor of 2.5 more abundant than in the local universe. The SDSS size function would also match the z = 0.9 CFHTLS size function very well with a similar change in number density. On the other hand, the CFHTLS size functions computed with a varying luminosity-size selection window with redshift remain constant if the selection window is shifted by 1.0$-$1.5 mag towards fainter magnitudes with decreasing redshift. There is a weak dependence on disk scale length with smaller ($h \lesssim $ 4 kpc) disks requiring more luminosity evolution than larger ones. Given that changes in number density are primarily due to mergers and that current estimates of merger rates below z = 1 are low, luminosity evolution appears to be a more plausible scenario to explain the observations.

description: Composite materials and technical textiles are increasingly used in biomedical applications. In the past few decades, research on artificial biomedical scaffolds manufactured from technical textiles have attracted much attention. Among many types of technical textiles, those made from PET fibres are most commonly used to repair knee ligaments due to their advantages including biocompatibility, biodegradability and suitable mechanical properties. The woven structure of a textile influences its the mechanical properties in many aspects, such as its tensile behaviour and shear behaviour, both of which being the main deformation modes that knee ligaments must sustain within human bodies. The aim of this thesis is to analyze the tensile and shear behaviours of three types of PET implantable artificial textile ligaments provided by manufacturer Neoligaments®. The first part of the work consists in applying tensile and shear loads on the three types of artificial textile ligaments and deriving the value of tensile stiffness and shear stiffness. Then, the experimental results were analyzed, and they were compared with the behaviour of real knee ligaments in order to assess whether the artificial textile ligaments provide adequate behaviour and stiffness. The second part of the work introduces early work done towards modelling the mechanical behaviour of the artificial textile ligaments. Finite element models were constructed from geometric models of the textiles built using textile modelling software TexGen. After applying tensile loads in ANSYS, stresses, strains and deformations in the models were analyzed. Based on the results, tensile stiffness of the models could be calculated. Although some limitations to the models lead to differences between these results and experimental values, the work enabled the identification of features of the models to be maintained in future work, and of features to be improved, towards the analysis of the mechanical properties of technical textiles and other non-linear, non-rigid structures.

description: Ferromagnet/superconductor heterostructures allow for the combination of unique physical phenomena offered by the both fields of magnetism and superconductivity. It was shown recently that spin waves can be efficiently scattered in such structures by a lattice of static or moving magnetic flux quanta (Abrikosov vortices), resulting in bandgaps in the spin-wave spectra. Here, we realize a nonreciprocal motion of a vortex lattice in nanoengineered symmetric and asymmetric pinning landscapes and investigate the non-reciprocal scattering of magnons on fluxons. We demonstrate that the magnon bandgap frequencies can be tuned by the application of a low-dissipative transport current and by its polarity reversal. Furthermore, we exploit the rectifying (vortex diode or ratchet) effect by the application of a 100 MHz-frequency ac current to deliberately realize bandgap up- or downshifts during one ac halfwave while keeping the bandgap frequency constant during the other ac halfwave. The investigated phenomena allow for the realization of energy-efficient hybrid magnonic devices, such as microwave filters with an ultra-high bandgap tunability of 10 GHz/mA and a fast modulation of the transmission characteristics on the 10 ns time scale.

description: We study a coarse homology theory with prescribed growth conditions. For a finitely generated group G with the word length metric this homology theory turns out to be related to amenability of G. We characterize vanishing of a certain fundamental class in our homology in terms of an isoperimetric inequality on G and show that on any group at most linear control is needed for this class to vanish. The latter is a homological version of the classical Burnside problem for infinite groups, with a positive solution. As applications we characterize existence of primitives of the volume form with prescribed growth and show that coarse homology classes obstruct weighted Poincare inequalities.

The isolation and characterization of recessive meiotic mutants in Neurospora crassa
Creators: name: DeLange, Aloysius

description: The study of the genetic control of meiosis has been initiated in Neurospora crassa by the isolation of recessive meiotic mutations. These mutations were detected by their reduced fertility or by the abortion of ascospores. To allow their expression, recessive meiotic mutations were made homozygous by selecting (n + 1) disomic ascospores. Cultures produced by each of these ascospores contain two types of nuclei with identical genes (including mutations) on all chromosomes except linkage group (LG) I, which contains the mating type locus. The simultaneous presence of these two types of nuclei allows the initiation of the sexual cycle, and therefore the detection of recessive mutations affecting the sexual cycle, including meiosis, on any chromosome except LG I. Using this method, three major classes of mutants have been detected. First, eleven mutants affecting perithecial development were expressed only as the maternal parent. Second, thirteen mutants produced perithecia with few or no ascospores. The infertility in two of these mutants was definitely caused by recessive mutations (asc-2 and asc-4). Finally, the abortion of many ascospores was detected in thirteen mutant strains. Among these strains, six recessive mutations (asc-1, asc-3, asc-5, asc-6, asc-7, and asc-8) caused the abortion of many ascospores. The dominant mutation SK(ad-3A) was detected in this screen for recessive mutations, because it caused ascospore abortion when crossed with an ad-3A mutant but not with a wild type strain. This mutation, apparently allelic to ad-3A, caused the abortion of all ad-3A-containing ascospores. The three ascospore abortion-type mutants asc-1, asc-3, and asc-6 were analyzed in more detail using both cytological and genetic methods. Ascospore abortion in these mutants was caused by abnormal disjunction of meiotic chromosomes. In mutants asc-1 and asc-6, the primary defect in pairing of homologs during the first meiotic prophase was followed by the formation of univalents at metaphase I. Observations on these mutants and on the mei-1 mutant (previously isolated; see Smith, 1975) suggested equational centromere division of many univalents at anaphase I. Subsequent irregular and prolonged separation of chromosomes at the second meiotic division appeared to be a secondary effect of the abnormal first division. The asc-3 mutant had a defect in ascus formation, and later in disjunction during the second meiotic and post-meiotic divisions. The first-acting defect before or during karyogamy resulted in the abortion of most cells. Some cells managed to proceed past this block. During the second meiotic division most chromosomes of the few resulting asci were attached to only one of the two spindle-pole bodies. Disjunction at the post-meiotic division was also highly irregular. This mutant appeared to be defective in the attachment of one spindle-pole body to a set of centromeres. The defect may involve either a centromere-associated product or a spindle-pole body.

description: This paper presents a novel three-degree-of-freedom (3-DOF) translational parallel manipulator (TPM) by using a topological design method of parallel mechanism (PM) based on position and orientation characteristic (POC) equations. The proposed PM is only composed of lower-mobility joints and actuated prismatic joints, together with the investigations on three kinematic issues of importance. The first aspect pertains to geometric modeling of the TPM in connection with its topological characteristics, such as the POC, degree of freedom and coupling degree, from which its symbolic direct kinematic solutions are readily obtained. Moreover, the decoupled properties of input-output motions are directly evaluated without Jacobian analysis. Sequentially, based upon the inverse kinematics, the singular configurations of the TPM are identified, wherein the singular surfaces are visualized by means of a Gr{ö}bner based elimination operation. Finally, the workspace of the TPM is evaluated with a geometric approach. This 3-DOF TPM features less joints and links compared with the well-known Delta robot, which reduces the structural complexity. Its symbolic direct kinematics and partially-decoupled property will ease path planning and dynamic analysis. The TPM can be used for manufacturing large work pieces.

description: Let Dtt denote the set of truth-table degrees. A bijection p from Dtt to Dtt is an automorphism if for all truth-table degrees x and y we have x <=tt y if and only if p(x) <=tt p(y). We say an automorphism p is fixed on some cone if there is a degree b such that for all x >=tt b we have p(x) = x. We first prove that for every 2-generic real X we have X' is not tt below X + 0'. We next prove that for every real X >=tt 0' there is a real Y such that Y + 0' =tt Y' =tt X. Finally, we use this to demonstrate that every automorphism of the truth-table degrees is fixed on some cone.

description: We propose a scheme for long-distance quantum communication where the elementary entanglement is generated through two-photon interference and quantum swapping is performed through one-photon interference. Local "polarization" maximally entangled states of atomic ensembles are generated by absorbing a single photon from on-demand single-photon sources. This scheme is robust against phase fluctuations in the quantum channels, moreover speeds up long-distance high-fidelity entanglement generation rate.

description: Quantum phase transitions occur at zero temperature, when the ground state of a Hamiltonian undergoes a qualitative change as a function of a control parameter. We consider a particularly interesting system with competing one-, two- and three-body interactions. Depending on the relative strength of these interactions, the ground state of the system can be a product state, or it can exhibit genuine tripartite entanglement. We experimentally simulate such a system in an NMR quantum simulator and observe the different ground states. By adiabatically changing the strength of one coupling constant, we push the system from one ground state to a qualitatively different ground state. We show that these ground states can be distinguished and the transitions between them observed by measuring correlations between the spins or the expectation values of suitable entanglement witnesses.

description: The first separation between quantum polynomial time and classical bounded-error polynomial time was due to Bernstein and Vazirani in 1993. They first showed a O(1) vs. Omega(n) quantum-classical oracle separation based on the quantum Hadamard transform, and then showed how to amplify this into a n^{O(1)} time quantum algorithm and a n^{Omega(log n)} classical query lower bound. We generalize both aspects of this speedup. We show that a wide class of unitary circuits (which we call dispersing circuits) can be used in place of Hadamards to obtain a O(1) vs. Omega(n) separation. The class of dispersing circuits includes all quantum Fourier transforms (including over nonabelian groups) as well as nearly all sufficiently long random circuits. Second, we give a general method for amplifying quantum-classical separations that allows us to achieve a n^{O(1)} vs. n^{Omega(log n)} separation from any dispersing circuit.
