description: The energy density of relic gravitational waves (GWs) emitted by primordial black holes (PBHs) is calculated. We estimate the intensity of GWs produced at quantum and classical scattering of PBHs, the classical graviton emission from the PBH binaries in the early Universe, and the graviton emission due to PBH evaporation. If nonrelativistic PBHs dominated the cosmological energy density prior to their evaporation, the probability of formation of dense clusters of PBHs and their binaries in such clusters would be significant and the energy density of the generated gravitational waves in the present day universe could exceed that produced by other known mechanisms. The intensity of these gravitational waves would be maximal in the GHz frequency band of the spectrum or higher and makes their observation very difficult by present detectors but also gives a rather good possibility to investigate it by present and future high frequency gravitational waves electromagnetic detectors. However, the low frequency part of the spectrum in the range $f\sim 0.1-10$ Hz may be detectable by the planned space interferometers DECIGO/BBO. For sufficiently long duration of the PBH matter dominated stage the cosmological energy fraction of GWs from inflation would be noticeably diluted.

description: Recent experiments have shown that nature violates noncontextual inequalities regardless of the state of the physical system. So far, all these inequalities involve measurements of dichotomic observables. We show that state-independent quantum contextuality can also be observed in the correlations between measurements of observables with genuinely continuous spectra, highlighting the universal character of the effect.

Microstructure from ferroelastic transitions using strain pseudospin clock models in two and three dimensions: a local mean-field analysis

subject: FOS: Physical sciences

description: We show how microstructure can arise in first-order ferroelastic structural transitions, in two and three spatial dimensions, through a local meanfield approximation of their pseudospin hamiltonians, that include anisotropic elastic interactions. Such transitions have symmetry-selected physical strains as their $N_{OP}$-component order parameters, with Landau free energies that have a single zero-strain 'austenite' minimum at high temperatures, and spontaneous-strain 'martensite' minima of $N_V$ structural variants at low temperatures. In a reduced description, the strains at Landau minima induce temperature-dependent, clock-like $\mathbb{Z}_{N_V +1}$ hamiltonians, with $N_{OP}$-component strain-pseudospin vectors ${\vec S}$ pointing to $N_V + 1$ discrete values (including zero). We study elastic texturing in five such first-order structural transitions through a local meanfield approximation of their pseudospin hamiltonians, that include the powerlaw interactions. As a prototype, we consider the two-variant square/rectangle transition, with a one-component, pseudospin taking $N_V +1 =3$ values of $S= 0, \pm 1$, as in a generalized Blume-Capel model. We then consider transitions with two-component ($N_{OP} = 2$) pseudospins: the equilateral to centred-rectangle ($N_V =3$); the square to oblique polygon ($N_V =4$); the triangle to oblique ($N_V =6$) transitions; and finally the 3D cubic to tetragonal transition ($ N_V =3$). The local meanfield solutions in 2D and 3D yield oriented domain-walls patterns as from continuous-variable strain dynamics, showing the discrete-variable models capture the essential ferroelastic texturings. Other related hamiltonians illustrate that structural-transitions in materials science can be the source of interesting spin models in statistical mechanics.

description: Detection of high-energy (~> 100 MeV) gamma rays by the Fermi Large Area Telescope (LAT) from a nova in the symbiotic binary system V407 Cygni has opened possibility of high-energy neutrino detection from this type of sources. Thermonuclear explosion on the white dwarf surface sets off a nova shell in motion that expands and slows down in a dense surrounding medium provided by the red giant companion. Particles are accelerated in the shocks of the shell, and interact with surrounding medium to produce observed gamma rays. We show that proton-proton interaction, which is most likely responsible for producing gamma rays via neutral pion decay, produces ~> 0.1 GeV neutrinos that can be detected by the current and future experiments at ~> 10 GeV.

description: Mise en contexte : Au Canada, environ 600 000 personnes font de l’insuffisance cardiaque (IC) avec une incidence de 50 000 par année. L’insuffisance cardiaque (IC) représente la 2ème cause d’hospitalisation chez les personnes âgées de 65 ans et plus avec une incidence plus élevée chez les hommes. L’IC pourrait être améliorée par les sessions éducatives selon l’approche d’enseignement bidrectionnel (‘teach-back’). Les autosoins sont de meilleure qualité lorsque la conjointe est activement impliquée dans tout le processus de prise en charge du patient. Cette étude a permis d’évaluer l’impact de l’approche d’enseignement bidirectionnel adapté aux couples sur les autosoins des franco-ontariens vivant en situation linguistique minoritaire dans la région d’Ottawa. Méthodologie : Afin de mieux répondre aux questions de recherche en lien avec la rétention des connaissances des couples et l’apport sur la relation conjugale, le devis mixte d’une étude de cas intégrée avec unités d’analyse multiples a été utilisé auprès de six couples franco-ottaviens dont le conjoint était atteint d’IC. Résultats : Les participants ont présenté une augmentation des connaissances des autosoins de l’IC de l’ordre de 27% entre la période avant l’intervention jusqu’à 30 jours après la formation. Il n’y a pas eu de réadmissions hospitalières parmi les participants. L’adaptation de l’approche d’enseignement bidirectionnel à la réalité individuelle des couples participants a eu un effet thérapeutique systémique sur la relation conjugale car cette approche a offert aux partenaires un cadre pour avoir une discussion ouverte sur l’impact réciproque de l’IC sur leur vécu quotidien. En assurant des visites aux domiciles des participants durant une phase post-hospitalisation considérée de grande vulnérabilité chez les patients IC, ce projet a pallié à la faille du système des soins parce qu’elle a permis à une transition sécuritaire des patients (et leurs conjointes) du milieu hospitalier en communauté. Conclusion : L’adaptation de l’approche d’enseignement bidirectionnel en français est une nouveauté pour les infirmières francophones œuvrant auprès des francophones vivant en situation linguistique minoritaire. Cette étude soutient l’importance d’intégrer la gérontandragogie dans les interventions éducatives des personnes âgées en matière de santé.

Testing the Distance-Duality Relation with Galaxy Clusters and Type Ia Supernovae

description: In this letter we propose a new and model-independent cosmological test for the distance-duality (DD) relation, η=D_{L}(z)(1+z)^{-2}/D_{A}(z)=1, where D_{L} and D_{A} are, respectively, the luminosity and angular diameter distances. For $D_L$ we consider two sub-samples of SNe type Ia taken from Constitution data (2009) whereas $D_A$ distances are provided by two samples of galaxy clusters compiled by De Fillipis et al. (2005) and Bonamente et al. (2006) by combining Sunyaev-Zeldovich effect (SZE) and X-ray surface brightness. The SNe Ia redshifts of each sub-sample were carefully chosen to coincide with the ones of the associated galaxy cluster sample (Δz<0.005) thereby allowing a direct test of DD relation. Since for very low redshifts, D_{A}(z) \approxeq D_{L}(z), we have tested the DD relation by assuming that $η$ is a function of the redshift parametrized by two different expressions: η(z) = 1 + η_{0}z and η(z) = 1 + η_{0}z/(1+z), where η_0 is a constant parameter quantifying a possible departure from the strict validity of the reciprocity relation (η_0=0). In the best scenario (linear parametrization) we obtain η_{0} = -0.28^{+ 0.44}_{- 0.44} (2σ$, statistical + systematic errors) for de Fillipis et al. sample (eliptical geometry), a result only marginally compatible with the DD relation. However, for Bonamente et al. sample (spherical geometry) the constraint is η_{0} = -0.42^{+ 0.34}_{- 0.34} (3σ$, statistical + systematic errors) which is clearly incompatible with the duality-distance relation.

description: The COVID-19 outbreak created one of the largest pandemics globally, with the world health organization (WHO) declaring several measures, including restriction of movement to curtail the spread of the virus. Reducing food waste is critical to achieving healthy nutrition and sustainability in food systems. In this regard, private households have consistently been regarded as key actors in food waste generation. Hence, this study examined the effects of the COVID-19 pandemic on food waste in homes. A total of 1098 respondents were asked questions on how the pandemic affected their food preparation and consumption pattern, food purchasing and food waste. Compared with the situation before COVID19, there is a significant increase in kitchen spending and bread-making at home. Moreover, food waste generation and the frequency of eating out and food purchasing were reduced. Waste generation was higher in bakery products, left-over foods, and fruits and vegetables. Respondents suggested prudent meal preparation and consumption, increased awareness, and food purchasing restrictions as measures to reduce food waste. Overall, the pandemic has led to more stringent planning in household spendings and attitudinal changes regarding food preparation and consumption, resulting in a significant reduction in food waste and may have contributed to curtailing the spread of the COVID-19 virus.

Understanding and modulating synaptic dysfunction in Huntington disease
Creators: name: Schmidt, Mandi Elizabeth
Publisher: name: University of British Columbia
Year: 2020

description: Huntington disease (HD) is a devastating neurodegenerative disorder caused by a CAG repeat expansion in the huntingtin gene. Early disrupted cortico-striatal (CS) transmission contributes to neuronal spine and synapse dysfunction primarily in striatal medium spiny neurons (MSNs), the most vulnerable cell type in HD, as well as in cortical neurons. Irreversible neurodegeneration of MSNs occurs with disease progression, leading to motor, cognitive, and psychiatric symptoms. However, synaptic dysfunction and spine loss are hypothesized to be therapeutically reversible before neuronal death occurs. One of the earliest alterations to occur in HD mouse models is enhanced striatal extrasynaptic (ex) N-methyl-D-aspartate receptor (NMDAR) expression and activity. This activity is mediated primarily through GluN2B subunit-containing receptors and is linked to increased activation of cell death pathways, inhibition of survival signaling, and greater susceptibility to excitotoxicity. Death-associated protein kinase 1 (DAPK1) is a pro-apoptotic kinase highly expressed in neurons during development. DAPK1 becomes re-activated and recruited to exNMDARs during ischemia where it phosphorylates GluN2B at S1303, amplifying receptor function. Approaches to reduce DAPK1 activity have demonstrated benefit in animal models of stroke, Alzheimer disease, Parkinson disease, and chronic stress, indicating that DAPK1 may be a novel target for neuroprotection. The overall hypothesis of this thesis was that aberrant DAPK1 activity contributes to exGluN2B dysfunction in HD, leading to early CS synaptic instability. An in vitro CS co-culture model was extensively optimized to allow rapid and robust detection of HD-like CS synaptic phenotypes, including MSN spine loss. Early dysregulation of DAPK1 was observed in the YAC128 HD mouse model, which was associated with elevated exGluN2B pS1303. Inhibition of DAPK1 normalized exGluN2B phosphorylation and surface expression, and completely prevented YAC128 MSN spine loss in CS co-culture. DAPK1 silencing restored nuclear CREB activation and partially rescued age-associated dendritic spine loss in vivo, thus validating DAPK1 as a target for synaptic protection in HD and warranting development of DAPK1-targeted therapies for neurodegeneration.

description: A simple method for constructing effective Hamiltonians for the 4fN and 4fN-15d energy levels of lanthanide ions in crystals from quantum-chemical calculations is presented. The method is demonstrated by deriving crystal-field and spin-orbit parameters for Ce3+ ions doped in LiYF4, Cs2NaYCl6, CaF2, KY3F10 and YAG host crystals from quantum chemical calculations based on the DV-Xα method. Good agreement between calculated and fitted values of the crystal-field parameters is obtained. The method can be used to calculate parameters even for low-symmetry sites where there are more parameters than energy levels.
Fundamental Quantitative Security In Quantum Key Distribution

Publisher: name: arXiv

subject: FOS: Physical sciences

description: We analyze the fundamental security significance of the quantitative criteria on the final generated key K in quantum key generation including the quantum criterion d, the attacker's mutual information on K, and the statistical distance between her distribution on K and the uniform distribution. For operational significance a criterion has to produce guarantee on the attacker's probability of correctly estimating some portion of K from her measurement, in particular her maximum probability of identifying the whole K. We distinguish between the raw security of K when the attacker just gets at K before it is used in a cryptographic context and its composition security when the attacker may gain further information during its actual use to help getting at K. We compare both of these securities of K to those obtainable from conventional key expansion with a symmetric key cipher. It is pointed out that a common belief in the superior security of a quantum generated K is based on an incorrect interpretation of d which cannot be true, and the security significance of d is uncertain. Generally, the QKD key K has no composition security guarantee and its raw security guarantee from concrete protocols is worse than that of conventional ciphers. Furthermore, for both raw and composition security there is an exponential catch up problem that would make it difficult to quantitatively improve the security of K in a realistic protocol. Some possible ways to deal with the situation are suggested.
Multiplicative Drift Analysis

Year: 2011
Subjects: subject: Neural and Evolutionary Computing (cs.NE)

description: In this work, we introduce multiplicative drift analysis as a suitable way to analyze the runtime of randomized search heuristics such as evolutionary algorithms. We give a multiplicative version of the classical drift theorem. This allows easier analyses in those settings where the optimization progress is roughly proportional to the current distance to the optimum. To display the strength of this tool, we regard the classical problem how the (1+1) Evolutionary Algorithm optimizes an arbitrary linear pseudo-Boolean function. Here, we first give a relatively simple proof for the fact that any linear function is optimized in expected time $O(n \log n)$, where $n$ is the length of the bit string. Afterwards, we show that in fact any such function is optimized in expected time at most ${(1+o(1)) 1.39 \euler n\ln (n)}$, again using multiplicative drift analysis. We also prove a corresponding lower bound of ${(1-o(1))e n\ln(n)}$ which actually holds for all functions with a unique global optimum. We further demonstrate how our drift theorem immediately gives natural proofs (with better constants) for the best known runtime bounds for the (1+1) Evolutionary Algorithm on combinatorial problems like finding minimum spanning trees, shortest paths, or Euler tours.

This approach allows as to simultaneously obtain a high-quality active layer together with a high photonic confinement as demonstrated through macro-, and micro-photoluminescence (μ-PL) and reflectivity experiments. A quality factor of 675 and a maximum PL emission at k=0 are evidenced thanks to μ-PL, revealing an efficient polaritonic relaxation even at low excitation power.

description: Urban agriculture is increasingly recognized as an important sustainable pathway for climate change adaptation and mitigation, for building more resilient cities, and for citizens’ health. Urban agriculture systems appear in many forms – both commercial and non-commercial. The value of the services derived from urban agriculture, e.g., enhanced food security, air quality, water regulation, and high level of biodiversity, is often difficult to quantify to inform policymakers and the general public in their decision making. We perform a contingent valuation survey of four different types of urban agriculture Where the citizens of Oslo are asked about their attitudes and willingness to pay non-commercial (urban community gardens and urban gardens for work training, education and kindergartens) and for commercial (i.e. aquaponics and vertical production) forms of urban agriculture. Results show that the citizens of Oslo are willing to increase their tax payments to contribute to further development of urban farming in Oslo.

We evolve nonadiabatic distributions assuming an equation of state that accounts for the anisotropy induced by the electric charge. Dissipation is described by streaming out or diffusion approximations. We match the interior solution, in noncomoving coordinates, with the Vaidya-Reissner-Nordström exterior solution. Two models are considered: i) a Schwarzschild-like shell in the diffusion limit; ii) a Schwarzschild-like interior in the free streaming limit. These toy models tell us something about the nature of the dissipative and electrically charged collapse. Diffusion stabilizes the gravitational collapse producing a spherical shell whose contraction is halted in a short characteristic hydrodynamic time. The streaming out radiation provides a more efficient mechanism for emission of energy, redistributing the electric charge on the whole sphere, while the distribution collapses indefinitely with a longer hydrodynamic time scale.

description: Identification of time-varying linear systems, which introduce both time-shifts (delays) and frequency-shifts (Doppler-shifts), is a central task in many engineering applications. This paper studies the problem of identification of underspread linear systems (ULSs), whose responses lie within a unit-area region in the delay Doppler space, by probing them with a known input signal. It is shown that sufficiently-underspread parametric linear systems, described by a finite set of delays and Doppler-shifts, are identifiable from a single observation as long as the time bandwidth product of the input signal is proportional to the square of the total number of delay Doppler pairs in the system. In addition, an algorithm is developed that enables identification of parametric ULSs from an input train of pulses in polynomial time by exploiting recent results on sub-Nyquist sampling for time delay estimation and classical results on recovery of frequencies from a sum of complex exponentials. Finally, application of these results to super-resolution target detection using radar is discussed. Specifically, it is shown that the proposed procedure allows to distinguish between multiple targets with very close proximity in the delay Doppler space, resulting in a resolution that substantially exceeds that of standard matched-filtering based techniques without introducing leakage effects inherent in recently proposed compressed sensing-based radar methods.

description: Contract-based nature protection schemes are a voluntary mechanism, with a limited contract duration, that aim to raise the acceptance of biodiversity conservation practices in agriculture among farmers and other land users. The purpose of this paper is to analyse the institutional settings of contract-based nature protection based on the– “Institutions of Sustainability” (IoS) framework in the German Rhine-Sieg district, and to outline the way in which policy measures should be designed to encourage farmers to participate in contract-based nature protection programmes. This was achieved by answering research questions to identify the challenges, potentials and obstacles of a contract-based nature protection scheme in different “sub-arenas” as defined in the IoS framework. Qualitative research methods were used as the methodology. The analysis shows that main constraints for sufficient implementation of contract-based nature protection schemes are the limited consideration of the impact of climate change during the contract period, the limited consideration of regional conditions as regards the measures taken on the ground and an inflexible contract duration.

Mott insulator dynamics

description: The hydrodynamics of a lattice Bose gas in a time-dependent external potential is studied in a mean-field approximation. The conditions under which a Mott insulating region can melt, and the local density adjust to the new potential, are determined. In the case of a suddenly switched potential, it is found that the Mott insulator stays insulating and the density will not adjust if the switch is too abrupt. This comes about because too rapid currents result in Bloch oscillation-type current reversals. For a stirrer moved through a Mott insulating cloud, it is seen that only if the stirrer starts in a superfluid region and the velocity is comparable to the time scale set by the tunneling, will the Mott insulator be affected.

Human-yeast cross-species complementation of chromosome instability genes

description: Humanized yeast offer a valuable resource with which to model and study human biology. Using cross-species complementation, model organisms like the budding yeast, Saccharomyces cerevisiae, can be utilized to measure the impact of tumor-specific mutations and screen for genetic vulnerabilities of genes overexpressed in cancer. To this end, we performed three parallel screens, one-to-one complementation screens for essential and nonessential yeast genes implicated in chromosome instability (CIN) and a pool-to-pool screen that queried all possible essential yeast genes for rescue of lethality by all possible human homologs. Our work identified 65 human cDNAs that can replace the null allele of essential yeast genes, including the nonorthologous pair yRFT1/hSEC61A1. For the nonessential yeast genes, 20 human-yeast complementation pairs were determined to be replaceable in 44 assays that test rescue of chemical sensitivity and/or CIN defects. For five human-yeast complementation pairs expressing human cDNAs encoding hLIG1, hSSRP1, hPPP1CA, hPPP1CC and hPPP2R1A, we introduced 45 tumor-specific missense mutations and assayed for growth defects and sensitivity to DNA-damaging agents in yeast. This set of human-yeast gene complementation pairs allows human genetic variants to be readily characterized in yeast, generating a prioritized list of somatic mutations that could contribute to chromosome instability in human tumors. We also selected a human-yeast pair expressing hFEN1, which is frequently overexpressed in cancer and is an anti-cancer therapeutic target, to perform synthetic dosage lethal (SDL) screens using ectopic overexpression of wild-type and catalytically inactive hFEN1 in yeast. The SDL screens identified homologous recombination (HR) repair mutants as synthetic dosage lethal with overexpression of catalytically-inactive hFen1. The SDL interactions were dependent on binding of hFen1 to DNA suggesting that toxicity was a result of catalytically inactive hFen1 becoming trapped on DNA and resulting in DNA damage. Our study establishes the utility of using cross-species complementation and ectopic overexpression to generate human-yeast genetic interaction networks and to model protein-inhibitor interactions using genetic approaches. Overall, these data establish the utility of this cross-species experimental approach.
