description: We devise a classical algorithm which efficiently computes the quantum expectation values arising in a class of continuous variable quantum circuits wherein the final quantum observable | after the Heisenberg evolution associated with the circuits | is at most second order in momentum. The classical computational algorithm exploits a specific epistemic restriction in classical phase space which directly captures the quantum uncertainty relation, to transform the quantum circuits in the complex Hilbert space into classical albeit unconventional stochastic processes in the phase space. The resulting multidimensional integral is then evaluated using the Monte Carlo sampling method. The work shows that for the specific class of computational schemes, Wigner negativity is not a sufficient resource for quantum speedup. It highlights the potential role of the epistemic restriction as an intuitive conceptual tool which may be used to study the boundary between quantum and classical computations.

description: Hardy-type arguments manifest Bell nonlocality in one of the simplest possible ways. Except for demonstrating nonclassical signature of entangled states in question, they can also serve for device-independent self-testing of states, as shown, e.g., in Phys. Rev. Lett. 109, 180401 (2012). Here we develop and broaden these results to an extended version of Hardy's argument, often referred to as Cabello's nonlocality argument. We show that, as in the simpler case of Hardy's nonlocality argument, the maximum quantum value for Cabello's nonlocality is achieved by a pure two-qubit state and projective measurements that are unique up to local isometries. We also examine the properties of a more realistic case when small errors in the ideal constraints are accepted within the probabilities obtained and prove that also in this case the two-qubit state and measurements are sufficient for obtaining the maximum quantum violation of the classical bound.

description: We derive symmetric and antisymmetric kernels by symmetrizing and antisymmetrizing conventional kernels and analyze their properties. In particular, we compute the feature space dimensions of the resulting polynomial kernels, prove that the reproducing kernel Hilbert spaces induced by symmetric and antisymmetric Gaussian kernels are dense in the space of symmetric and antisymmetric functions, and propose a Slater determinant representation of the antisymmetric Gaussian kernel, which allows for an efficient evaluation even if the state space is high-dimensional. Furthermore, we show that by exploiting symmetries or antisymmetries the size of the training data set can be significantly reduced. The results are illustrated with guiding examples and simple quantum physics and chemistry applications.

description: La Cannabis sativa, es una planta de distribución mundial por sus efectos psicotrópicos. Sin embargo, esta planta también tiene propiedades analgésicas, antidepresivas, hipnóticas, inmunosupresoras, antiinflamatorias, ansiolíticas, antitumorales y antioxidantes, entre otras. Se absorbe principalmente por inhalación, tiene una alta distribución en los tejidos muy vascularizados por su liposolubilidad, se metaboliza principalmente en el hígado y su excreción es a través de heces fecales y orina. Dentro de sus componentes se encuentran los cannabinoides, compuestos químicos terpenofenólicos de 21 y 22 carbonos, formados principalmente por tres anillos: ciclohexeno, tetrahidropirano y benceno. Los cannabinoides más estudiados por su poder farmacológico son el ∆-9-Tetrahidrocannabinol (∆-9-THC) y el Cannabidiol (CBD). Las especies reactivas de oxígeno (ERO`s) son moléculas que contienen oxígeno y son altamente reactivas e inestables, que alteran la homeóstasis celular, se producen de manera normal en los procesos metabólicos de la célula y también se generan de fuentes exógenas como contaminación ambiental, metales pesados, sustancias químicas, radiaciones, etc. y son estabilizadas por sustancias llamadas antioxidantes. Cuando hay un desequilibrio entre los antioxidantes y las ERO´s, la célula entra en un estrés oxidativo, causando daño al ADN, las proteínas y los lípidos en las células induciendo patologías como: enfermedades crónico degenerativas, trastornos autoinmunes y neurodegenerativos, entre otros. En este trabajo nos enfocamos a revisar de manera general, los efectos benéficos de los cannabinoides ∆-9-THC y CBD de la Cannabis sativa en algunas enfermedades y como agentes antioxidantes que disminuyen el estrés celular.

description: Casimir pistons are models in which finite Casimir forces can be calculated without any suspect renormalizations. It has been suggested that such forces are always attractive, but we present several counterexamples, notably a simple type of quantum graph in which the sign of the force depends upon the number of edges. We also show that Casimir forces in quantum graphs can be reliably computed by summing over the classical orbits, and study the rate of convergence of the periodic orbit expansion. In generic situations where no analytic expression is available, the sign and approximate magnitude of Casimir forces can often be obtained using only the shortest classical orbits.

description: Control of electron spin decoherence in contact with a mesoscopic bath of many interacting nuclear spins in an InAs quantum dot is studied by solving the coupled quantum dynamics. The nuclear spin bath, because of its bifurcated evolution predicated on the electron spin up or down state, measures the which-state information of the electron spin and hence diminishes its coherence. The many-body dynamics of nuclear spin bath is solved with a pair-correlation approximation. In the relevant timescale, nuclear pair-wise flip-flops, as elementary excitations in the mesoscopic bath, can be mapped into the precession of non-interacting pseudo-spins. Such mapping provides a geometrical picture for understanding the decoherence and for devising control schemes. A close examination of nuclear bath dynamics reveals a wealth of phenomena and new possibilities of controlling the electron spin decoherence. For example, when the electron spin is flipped by a $π$-pulse at $τ$, its coherence will partially recover at $\sqrt{2}τ$ as a consequence of quantum disentanglement from the mesoscopic bath. In contrast to the re-focusing of inhomogeneously broadened phases by conventional spin-echoes, the disentanglement is realized through shepherding quantum evolution of the bath state via control of the quantum object. A concatenated construction of pulse sequences can eliminate the decoherence with arbitrary accuracy, with the nuclear-nuclear spin interaction strength acting as the controlling small parameter.

description: We consider an identity relating Fibonacci numbers to Pascal's triangle discovered by G. E. Andrews. Several authors provided proofs of this identity, all of them rather involved or else relying on sophisticated number theoretical arguments. We not only give a simple and elementary proof, but also show the identity generalizes to arrays other than Pascal's triangle. As an application we obtain identities relating trinomial coefficients and Catalan's triangle to Fibonacci numbers.

description: Automating the derivation of published results is a challenge, in part due to the informal use of mathematics by physicists, compared to that of mathematicians. Following demand, we describe a method for converting informal hand-written derivations into datasets, and present an example dataset crafted from a contemporary result in condensed matter. We define an equation reconstruction task completed by rederiving an unknown intermediate equation posed as a state, taken from three consecutive equational states within a derivation. Derivation automation is achieved by applying string-based CAS-reliant actions to states, which mimic mathematical operations and induce state transitions. We implement a symbolic similarity-based heuristic search to solve the equation reconstruction task as an early step towards multi-hop equational inference in physics.

description: Valley-polarized quantum Hall states in graphene are described by a Heisenberg O(3) ferromagnet model, with the ordering type controlled by the strength and sign of valley anisotropy. A mechanism resulting from electron coupling to strain-induced gauge field, giving leading contribution to the anisotropy, is described in terms of an effective random magnetic field aligned with the ferromagnet z axis. We argue that such random field stabilizes the XY ferromagnet state, which is a coherent equal-weight mixture of the $K$ and $K'$ valley states. Other implications such as the Berezinskii-Kosterlitz-Thouless ordering transition and topological defects with half-integer charge are discussed.

description: The characteristic electron densities, temperatures, and thermal distributions of 1MK active region loops are now fairly well established, but their coronal magnetic field strengths remain undetermined. Here we present measurements from a sample of coronal loops observed by the Extreme-ultraviolet Imaging Spectrometer (EIS) on Hinode. We use a recently developed diagnostic technique that involves atomic radiation modeling of the contribution of a magnetically induced transition (MIT) to the Fe X 257.262A spectral line intensity. We find coronal magnetic field strengths in the range of 60--150G. We discuss some aspects of these new results in the context of previous measurements using different spectropolarimetric techniques, and their influence on the derived Alfvén speeds and plasma $β$ in coronal loops.

description: We study the longitudinal spin susceptibility inside a magnetically ordered phase, which exhibits a superconducting instability leading to a coexistence of the two ordered phases. Inside the magnetic phase, the superconducting gap acquires a linear term in a magnetic field applied along the direction of the magnetic moment. We find that such a linear term generates a jump of the longitudinal spin susceptibility when the superconducting instability occurs via a continuous phase transition. This anomaly at the superconducting instability is a thermodynamic signature of the microscopic coexistence of superconductivity and magnetism, and can be a general feature associated with the breaking of spin rotational symmetry inside the magnetic phase.

description: We study the problems related to the renormalization of propagators in Resonance Chiral Theory, concentrating on the case of vector $1^{--}$ resonances in the antisymmetric tensor formalism. We have found that renormalization of the divergences of the self-energy graphs needs new type of kinetic counterterms with two derivatives which are not present in the original leading order Lagrangian. The general form of the propagator for antisymmetric tensor fields could then contain not only poles corresponding to the original $1^{--}$ resonance states but also to the additional states with opposite parity which decouple in the free field limit. In some cases, these dynamically generated additional states might be negative norm ghosts or tachyons.

Isolation and mapping of clones from human chromosome 5
Creators: name: Bernard, Lynn Elizabeth
Publisher: name: University of British Columbia
Year: 2008

description: This thesis describes the isolation and mapping of DNA clones from human chromosome 5, with emphasis on the 5q11.2-q13.3 region. This region is of interest because of a Vancouver family in which trisomy for the 5q11.2-q13.3 region co segregates with schizophrenia and renal anomalies. The 5q11.2-q13.3 region is of additional interest since chronic spinal muscular atrophy has been linked to markers within this region. A novel technique, Alu PCR differential hybridization, was developed to isolate clones from the 5q11.2-q13.3 region. The somatic cell hybrid HHW1O64 contains a chromosome 5 with an interstitial deletion of 5q11.2-q13.3, derived from a carrier member of the family segregating for the segmental trisomy. Alu PCR differential hybridization was used to isolate twenty chromosome 5 clones absent from the HHW1O64 hybrid. Radiation hybrid mapping was used to determine a rough order of clones isolated by Alu PCR differential hybridization. Order information was used to select clones to screen for polymorphisms. Nine polymorphic systems were detected. Multipoint linkage mapping of two of the new polymorphisms (D5S257 and D5S268) placed them onto the p arm of chromosome 5. This result was unexpected, since D5S257 and D5S268 were isolated based on their absence from the HHW1O64 hybrid. The HHW1O64 somatic cell hybrid therefore contains a deletion within the p arm of chromosome 5 in addition to the expected interstitial deletion of 5q11.2- q13.3. Analysis of D5S257 and D5S268 in the family segregating for the segmental trisomy indicated that the rearrangement in this family does not involve Sp. Multipoint linkage analysis of the polymorphism associated with D5S260 placed this marker between two chromosome 5 index markers (D5S76 and D5S21) which had been mapped outside the 5q11.2-q13.3 interstitial deletion in HHW1O64. This map position was unexpected, since D5S260 was isolated on the basis of absence from the HHW1O64 hybrid. The most likely explanation for the inconsistency between the linkage and somatic cell hybrid data is that the chromosome 5 present in the HHW1O64 hybrid is deleted for DNA both proximal and distal to D5S76. This complex 5q rearrangement is present in the family segregating for the segmental trisomy, based on the analysis of D5S260 and D5S76 in this family.

description: The two dimensional supersymmetric CP(N-1) model has a striking similarity to the N=2 supersymmetric gauge theory in four dimensions. The BPS mass formula and the curve of the marginal stability (CMS), which exist in the four dimensional gauge theory, appears in this two dimensional CP(N-1) model. These two quntities are derived by a one-dimensional n-vector spin model in the large n limit for the N=2 case. This mapping is further investigated at the critical point. An application of the study of the BPS mass formula is proposed to the phenomena of the spin and charge separations in the Higgs phase.

description: Superanalysis can be deformed with a fermionic star product into a Clifford calculus that is equivalent to geometric algebra. With this multivector formalism it is then possible to formulate Riemannian geometry and an inhomogeneous generalization of exterior calculus. Moreover it is shown here how symplectic and Poisson geometry fit in this context. The application of this formalism together with the bosonic star product formalism of deformation quantization leads then on space and space-time to a natural appearance of spin structures and on phase space to BRST structures that were found in the path integral formulation of classical mechanics. Furthermore it will be shown that Poincare and Lie-Poisson reduction can be formulated in this formalism.

The effects of respiratory and metabolic acidosis on the metabolic rate of anaesthetized, paralyzed, and artificially ventilated ground squirrels (Spermophilus lateralis)
Creators: name: Bharma, Supriti
Publisher: name: University of British Columbia

description: This study was designed to test the hypothesis that changes in arterial pH (pHa) reflecting proportional changes in arterial hydrogen ion concentration ([H+]a) effect a change in oxygen consumption (VO2) or metabolic rate (MR), in euthertnic golden mantled ground squirrels (Spermophilus lateralis). Of interest were the specific effects, either local or reflex, of changing arterial pH on metabolic rate . Therefore, it was imperative that experimentally produced changes in pHa did not cause any compensatory changes in ventilation, since this would indirectly alter metabolic rate due to changes in the cost of breathing . It was also important that any changes in metabolic rate produced by the experimental manipulations did not cause any change in body temperature (Tb), since this would secondarily cause further changes in metabolic rate . As a consequence, these experiments were conducted on anaesthetized, paralyzed, and artificially ventilated animals maintained at constant Tb. Three series of experiments were conducted, each of which altered pHa in a different fashion. In the first series of experiments, (Series I, n = 6) pHa was randomly made either alkalotic or acidotic by altering the frequency and/or volume of the respirator, to increase or decrease minute ventilation (VE), and consequently hyper- or hypo-ventilate the animals . The average pHa was varied from 7 .19 ± 0.03 Units in the acidotic range, to 7 .55 ± 0.02 Units in the alkalotic range with corresponding arterial partial pressures of CO 2 (Paco2) of 52.8 ± 3 Torr and 25.9 ± 2 Torr, respectively. In this series, VO2 showed a significant (p < 0.001) positive correlation with pHa (r = + 0.84), decreasing 0 .24 ml.min-1 for every 0 .1 Unit decrease in pHa. (a 21 .78% decrease in metabolic rate for a decrease of 0 .36 pHa Units or a 6 .04% decrease in metabolic rate for each 0.1 unit decrease in pHa). [More abstract follows]

description: The recent advanced LIGO/Virgo detections of gravitational waves (GWs) from stellar binary black hole (BBH) mergers, in particular GW190521, which is potentially associated with a quasar, have stimulated renewed interest in active galactic nuclei (AGNs) as factories of merging BBHs. Compact objects evolving from massive stars are unavoidably enshrouded by a massive envelope to form accretion-modified stars (AMSs) in the dense gaseous environment of a supermassive black hole (SMBH) accretion disk. We show that most AMSs form binaries due to gravitational interaction with each other during radial migration in the SMBH disk, forming BBHs inside the AMS. When a BBH is born, its orbit is initially governed by the tidal torque of the SMBH. Bondi accretion onto BBH at a hyper-Eddington rate naturally develops and then controls the evolution of its orbits. We find that Bondi accretion leads to efficient removal of orbital angular momentum of the binary, whose final merger produces a GW burst. Meanwhile, the Blandford-Znajek mechanism pumps the spin energy of the merged BH to produce an electromagnetic counterpart (EMC). Moreover, hyper-Eddington accretion onto the BBH develops powerful outflows and triggers a Bondi explosion, which manifests itself as a EMC of the GW burst, depending on the viscosity of the accretion flow. Thermal emission from Bondi sphere appears as one of EMCs. BBHs radiate GWs with frequencies $\sim 10^{2}\,$Hz, which are accessible to LIGO.

description: This thesis examines the involvement of local governments in the Greek Energy Market. A brief historical review is followed by a presentation of the ways local governments can actively participate in the Greek energy market. It then examines the benefits that local governments can derive from the adoption of energy saving and energy netting practices aiming at their energy autonomy, as well as from the use of cyclical economy rules. The last chapter focuses on the financial tools available for energy investments involving local governments

description: The performance of image classification methodsheavily relies on the high-quality annotations, which are noteasily affordable, particularly for medical data. To alleviate thislimitation, in this study, we propose a weakly supervised imageclassification method based on combination of hand-craftedfeatures. We hypothesize that integration of these hand-craftedfeatures alongside Long short-term memory (LSTM) classifiercan reduce the adverse effects of weak labels in classificationaccuracy. Our proposed algorithm is based on selecting theappropriate domain representations of the data in Wavelet andDiscrete Cosine Transform (DCT) domains. This informationis then fed into LSTM network to account for the sequentialnature of the data. The proposed efficient, low dimensionalfeatures exploit the power of shallow deep learning modelsto achieve higher performance with lower computational cost.In order to show efficacy of the proposed strategy, we haveexperimented classification of brain tumor grades and achievedthe state of the art performance with the resolution of 256 x 256. We also conducted a comprehensive set of experiments toanalyze the effect of each component on the performance.

description: Lattice QCD with $N_f=2$ flavours of sea quark is used to explore the spectrum and decay of scalar mesons. We are able to determine the $b_1$ - $a_0$ mass difference and this leads to the conclusion that the lightest non-singlet scalar meson ($a_0$) has a mass of 1.01(4) GeV. We determine from the lattice the coupling strength to KK and $πη$. We compute the leptonic decay constant of the lightest non-singlet scalar meson. We discuss the impact of these lattice results on the interpretation of the $a_0(980)$ state. We also discuss $K^*_0$ states.

description: In the framework of Regge phenomenology, masses of the charmed states $c\bar{q} (q=u,d,s)$ lying on the $1^3S_1$-like trajectories are estimated. The overall agreement between our estimated masses and the recent predictions given by modified quark models[hep-ph/0605019, hep-ph/0608011, hep-ph/0608139] is good. Masses of the observed charmed states $D_{s0}(2317)$, $D_{sJ}(2860)$ and $D_{sJ}(2690)$/$D_{sJ}(2700)$ can be reasonably reproduced in the picture of these charmed states as simple quark-antiquark configurations. We therefore suggest the $D_{s0}(2317)$ can be identified as the $c\bar{s}(1^3P_0)$ states. The possible assignments of the $D_{sJ}(2860)$ and $D_{sJ}(2690)$/ $D_{sJ}(2700)$ are discussed.

description: Στην παρούσα μελέτη συντέθηκαν ακόρεστες πολυεστερικές ρητίνες με βάση το ηλετρικό οξύ, την αιθυλενογλυκόλη, την πολυ( αιθυλενογλυκόλη) 200 και τον μηλεϊνικό ανυδρίτη. Η σύνθεση των ρητινών έγινε με πολυμερισμό συμπύκνωσης τόσο σε δύο στάδια όσο και σε ένα στάδιο. Η σύνθεση των ρητινών επιβεβαιώθηκε με φασματοσκοπικές τεχνικές πυρηνικού μαγνητικού συντονισμού (1H NMR) και υπερύθρου (FTIR). Στην συνέχεια έγινε δικτύωση των ρητινών η οποία εξετάστηκε με την τεχνική της διαφορικής θερμιδομετρίας σάρωσης (DSC). Τα δικτυωμένα υλικά που προέκυψαν εξετάστηκαν ως προς τη θερμική τους σταθερότητα με θερμοσταθμική ανάλυση (TGA) και ως προς τις μηχανικές τους ιδιότητες με τον προσδιορισμό της αντοχής στον εφελκυσμό. Τα αποτελέσματα έδειξαν ότι τα υλικά που συντέθηκαν με πολυμερισμό δύο σταδίων δεν ήταν δυνατό να αναμιχθούν με τα δικτυωτικά μέσα καθώς ήταν στερεά με υψηλά σημεία τήξης. Τα υλικά που συντέθηκαν με πολυμερισμό ενός σταδίου ήταν αναμίξιμα με τα δικτυωτικά μέσα και δικτυώθηκαν με επιτυχία σε διαφορετικές αναλογίες. Ο έλεγχος των θερμικών ιδιοτήτων των πολυμερών έδειξε ότι η αποικοδόμηση των υλικών γίνεται σε δυο στάδια, ενώ αύξηση του μήκους της χρησιμοποιούμενης διόλης μειώνει τη θερμική σταθερότητα των υλικών. Τέλος, από τις μετρήσεις των μηχανικών ιδιοτήτων υπό εφελκυσμό φάνηκε πως η αύξηση της αναλογίας του δικτυωτικού μέσου μειώνει την επιμήκυνση στη θραύση και αυξάνει την τάση στο σημείο θραύσης
description: In this study unsaturated polyester resins were synthesized based on succinic acid, ethylene glycol, poly( ethylene glycol) 200 and maleic anhydride. The resin synthesis was conducted both via two-step polymerization and one-step polymerization. The structure of the materials was determined with nuclear magnetic resonance spectroscopy (1H NMR) and infrared spectroscopy (FTIR). Cross-linking of the resins was examined with differential scanning calorimetry and the cross-linked materials were characterized with thermogravimetric analysis (TGA) and mechanical strain tests. Materials synthesized with two-step polymerization weren’t miscible with the reactive diluent as they were solids with high melting temperature. Materials prepared via one-step polymerization were miscible with reactive diluents and they were successfully cross-linked in various ratios. Thermal degradation of the cross-linked materials happens in two stages and the increase of the aliphatic chain of the diol results in lower thermal stability. Finally, mechanical testing showed that increase in the ratio of reactive diluent results in higher tensile stress at break and lower tensile strain

description: Cosmic rays from outer space enter the atmosphere with energies of up to 10^{11} GeV. The initial particle or a secondary hadron inside the shower may then interact with an air nucleon to produce nonstandard particles. In this article we study the production of new physics by high energy cosmic rays, focusing on the long-lived gluino of split-SUSY models and a WIMP working as dark matter. We first deduce the total flux of hadron events at any depth in the atmosphere, showing that secondary hadrons can not be neglected. Then we use these results to find the flux of gluinos and WIMPs that reach the ground after being produced inside air showers. We also evaluate the probability of producing these exotic particles in a single proton shower of ultrahigh energy. Finally we discuss the possible signal in current and projected experiments. While the tiny flux of WIMPs does not seem to have any phenomenological consequences, we show that the gluinos could modify substantially the profile of a small fraction of extensive air showers. In particular, they could produce a distinct signal observable at AUGER in showers of large zenith angle.

description: In this article, we study locating-dominating codes in binary Hamming spaces $\mathbb{F}^n$. Locating-dominating codes have been widely studied since their introduction in 1980s by Slater and Rall. They are dominating sets suitable for distinguishing vertices in graphs. Dominating sets as well as locating-dominating codes have been studied in Hamming spaces in multiple articles. Previously, Honkala et al. (2004) have presented a lower bound for locating-dominating codes in binary Hamming spaces. In this article, we improve the lower bound for all values $n\geq10$. In particular, when $n=11$, we manage to improve the previous lower bound from $309$ to $317$. This value is very close to the current best known upper bound of $320$.
