description: We study quotients of the Weyl algebra by left ideals whose generators consist of an arbitrary Z^d-graded binomial ideal I along with Euler operators defined by the grading and a parameter in C^d. We determine the parameters for which these D-modules (i) are holonomic (equivalently, regular holonomic, when I is standard-graded); (ii) decompose as direct sums indexed by the primary components of I; and (iii) have holonomic rank greater than the generic rank. In each of these three cases, the parameters in question are precisely those outside of a certain explicitly described affine subspace arrangement in C^d. In the special case of Horn hypergeometric D-modules, when I is a lattice basis ideal, we furthermore compute the generic holonomic rank combinatorially and write down a basis of solutions in terms of associated A-hypergeometric functions. This study relies fundamentally on the explicit lattice point description of the primary components of an arbitrary binomial ideal in characteristic zero, which we derive in our companion article arxiv:0803.3846.

description: In traditional cochlear implant surgery, physical trauma may occur during electrode array insertion. Magnetic guidance of the electrode array has been proposed to mitigate this medical complication. After insertion, the guiding magnet attached to the tip of the electrode array must be detached via a heating process and removed. This heating process may, however, cause thermal trauma within the cochlea. In this study, a validated three-dimensional finite element heat transfer model of the human cochlea is applied to perform an intracochlear thermal analysis necessary to ensure the safety of the magnet removal phase. Specifically, the maximum safe input power density to detach the magnet is determined as a function of the boundary conditions, heating duration, cochlea size, implant electrode array radius and insertion depth, magnet size, and cochlear fluid. A dimensional analysis and numerical simulations reveal that the maximum safe input power density increases with increasing cochlea size and the radius of the electrode array, whereas it decreases with increasing electrode array insertion depth and magnet size. The best cochlear fluids from the thermal perspective are perilymph and a soap solution. Even for the worst case scenario in which the cochlear walls are assumed to be adiabatic except at the round window, the maximum safe input power density is larger than that required to melt 1 $\rm{mm^3}$ of paraffin bonding the magnet to the implant electrode array. By combining the outcome of this work with other aspects of the design of the magnetic insertion process, namely the magnetic guidance procedure and medical requirements, it will be possible to implement a thermally safe patient-specific surgical procedure.

description: So far most of the analysis of coronavirus 2020 epidemic data has been focusing on a short-time window and consequently a quantitative test of statistical physical laws of Coronavirus Epidemics with Containment Measures (CEwCM) is currently lacking. Here we report a quantitative analysis of CEwCM over 230 days, covering the full-time lapse of the first epidemic wave. We use a 3D phase diagram tracking the simultaneous evolution of the doubling time Td(t) and reproductive number Rt(t) showing that this expanded parameter space is needed for biological physics of CEwCP. We have verified that in the supercritical [Rt(t)>1, Td(t)<40 days] regime i) the curve Z(t) of total infected cases follows the growth rate called Ostwald law; ii) the doubling time follows the exponential law Td(t)=A exp((t-t0)/s) as a function of time and iii) the power law Td(t)=C(Rt(t)-1)^-n is verified with the exponent n depending on the definition of Rt(t). The log-log plots Td(t) versus (Rt-1) of the second 2020 epidemic wave unveil in the subcritical regime [Td(t)>100 days] arrested metastable phases with Rt>1 where Td(t) was kept constant followed by its explosion and its containment following the same power law as in the first wave

Possible post-kick jets in SN 1987A
Creators: name: Soker, Noam
Publisher: name: arXiv
Year: 2020
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)
subject: FOS: Physical sciences

description: I suggest that the recently observed hot-dust elongated structure that likely engulfs the neutron star (NS) remnant of supernova (SN) 1987A was shaped by jets that the NS launched shortly after it acquired its natal kick velocity. I take the axis of the two post-kick jets to be along the long dimension of the hot-dust elongated structure, which I term the bipolar lobe. The jittering jets explosion mechanism accounts for the misalignment of the post-kick jets axis and the main-jets axis of the ejecta. For post-kick jets to shape the bipolar lobe their energy should have been about equal to the energy of the ejecta inner to the outer edge of the lobe, E(2j)~E(ej,lobe)~4.6e48erg. For an efficiency of 0.01-0.1 to convert accretion energy to post-kick jets' energy I estimate that the post-kick accreted mass was Macc~0.0002-0.002Mo. The negative jets feedback mechanism, where jets remove some of the mass that could have been accreted, accounts for the limited amount of accreted mass. This study adds to the growing recognition of the importance of jets in core collapse supernovae, including post-explosion jets.

Women’s centres to the rescue : an examination of the contributions women’s centres have made to communities throughout British Columbia
Creators: name: Rucci, Cristina
Publisher: name: University of British Columbia
Year: 2009

description: The purpose of this thesis is to illustrate the way in which feminist-based organizations - specifically women's centres - have sought to fulfill the unmet social needs of women and children living throughout British Columbia. This thesis achieves this end through a number of different means. A literature review provides background on feminist planning and an overview of the history of the women's movement in Canada. An examination of B.C. women's centres, which includes a close look at the similar and unique services offered, demonstrates the positive contributions made by centres. A case study, which thoroughly reviews the history of one specific centre (the North Shore Women's Centre), shows how women's centres evolve over time in order to meet the changing needs of the women in their communities. An analysis explores the opportunities and constraints that the members of women's centres have faced in trying to carry out their various activities. This thesis has been based on, and has utilized, the goals and methodologies created by feminist planners. In doing so, it takes women's needs, interests, and experiences into account, and aims to make a contribution to knowledge that women can use to improve their lives

Superfluid-normal phase transition in finite systems and its effect on damping of hot giant resonances
Creators: name: Dang, Nguyen Dinh
Publisher: name: arXiv
Year: 2006
Subjects: subject: Nuclear Theory (nucl-th)
subject: FOS: Physical sciences

description: Thermal fluctuations of quasiparticle number are included making use of the secondary Bogolyubov's transformation, which turns quasiparticles operators into modified-quasiparticle ones. This restores the unitarity relation for the generalized single-particle density operator, which is violated within the Hartree-Fock-Bogolyubov (HFB) theory at finite temperature. The resulting theory is called the modified HFB (MHFB) theory, whose limit of a constant pairing interaction yields the modified BCS (MBCS) theory. Within the MBCS theory, the pairing gap never collapses at finite temperature T as it does within the BCS theory, but decreases monotonously with increasing T. It is demonstrated that this non-vanishing thermal pairing is the reason why the width of the giant dipole resonance (GDR) does not increase with T up to T around 1 MeV. At higher T, when the thermal pairing is small, the GDR width starts to increase with T. The calculations within the phonon-damping model yield the results in good agreement with the most recent experimental systematic for the GDR width as a function of T. A similar effect, which causes a small GDR width at low T, is also seen after thermal pairing is included in the thermal fluctuation model.

description: Ranking vertices of multidimensional networks is crucial in many areas of research, including selecting and determining the importance of decisions. Some decisions are significantly more important than others, and their weight categorization is also imortant. This paper defines a completely new method for determining the weight decisions using artificial intelligence for importance ranking of three-dimensional network vertices, improving the existing Ordered Statistics Vertex Extraction and Tracking Algorithm (OSVETA) based on modulation of quantized indices (QIM) and error correction codes. The technique we propose in this paper offers significant improvements the efficiency of determination the importance of network vertices in relation to statistical OSVETA criteria, replacing heuristic methods with methods of precise prediction of modern neural networks. The new artificial intelligence technique enables a significantly better definition of the 3D meshes and a better assessment of their topological features. The new method contributions result in a greater precision in defining stable vertices, significantly reducing the probability of deleting mesh vertices.

description: We are reaching the point where spectropolarimetric surveys have run for long enough to reveal solar-like magnetic activity cycles. In this paper we investigate what would be the best strategy to identify solar-like magnetic cycles and ask which large-scale magnetic field parameters best follow a solar-type magnetic cycle and are observable with the Zeeman-Doppler-Imaging (ZDI) technique. We approach these questions using the 3D non-potential flux transport simulations of \cite{Yeates2012} modelling the solar vector magnetic field over 15 years (centred on solar cycle 23). The flux emergence profile was extracted from solar synoptic maps and used as input for a photospheric flux transport model in combination with a non-potential coronal evolution model. We synthesise spectropolarimetric data from the simulated maps and reconstruct them using ZDI. The ZDI observed solar cycle is set into the context of other cool star observations and we present observable trends of the magnetic field topology with time, sunspot number and S-index. We find that the axisymmetric energy fraction is the best parameter of the ZDI detectable large-scale field to trace solar-like cycles. Neither the surface averaged large-scale field or the total magnetic energy is appropriate. ZDI seems also to be able to recover the increase of the toroidal energy with S-index. We see further that ZDI might unveil hints of the dynamo modes that are operating and of the global properties of the small-scale flux emergence like active latitudes.

description: The explosion of IoT and wearable devices determined a rising attention towards energy harvesting as source for powering these systems. In this context, many applications cannot afford the presence of a battery because of size, weight and cost issues. Therefore, due to the intermittent nature of ambient energy sources, these systems must be able to save and restore their state, in order to guarantee progress across power interruptions. In this work, we propose a specialized backup/restore controller that dynamically tracks the memory accesses during the execution of the program. The controller then commits the changes to a snapshot in a Non-Volatile Memory (NVM) when a power failure is detected. Our approach does not require complex hybrid memories and can be implemented with standard components. % and integrated in any MCU with Results on a set of benchmarks show an average $8\times$ reduction in backup size. Thanks to our dedicated controller, the backup time is further reduced by more than $100\times$, with an area and power overhead of only 0.4\% and 0.8\%, respectively, w.r.t. a low-end IoT node.
Analysis of the main factors in the resilience of the banking system: a multiple case study

Year: 2024

description: Crises are distressing and critical moments in all contexts, but when it comes to crises affecting the banking system, which is considered the engine of any country's economy, several risks, whether internal or external, can emerge and spread throughout the global banking system. The 2008 crisis is an emblematic example. After this financial distress, all decision-makers were convinced that resilience measures are an absolute priority to reduce fragility and strengthen the solidity of the system in order to face the most challenging scenarios. This study adopts a qualitative inductive approach, analyzing multiple case studies to investigate the factors influencing banking sector resilience. The study leverages data from stress tests conducted by regulatory bodies such as the Federal Reserve, the Bank of Canada, and Bank Al Maghrib. Despite improvements in capital ratios exceeding Basel III expectations, persistent weaknesses remain, particularly evident in the United States, where stress tests failed to prevent widespread bank failures. This study highlights the importance of regulatory measures, stress testing, and effective supervision in bolstering banking sector resilience against economic and financial shocks. By understanding the lessons gleaned from global case studies, policymakers and stakeholders can implement proactive measures to fortify the resilience of banking systems worldwide.

The bound is based on the concept that any classical or quantum protocol to evaluate a function on distributed inputs can be turned into a quantum communication protocol. As an application of this bound, we give a very simple proof of the statement that almost all Boolean functions on n+n bits have linear communication complexity, even in the presence of unlimited entanglement.

description: Blazar variability may be driven by stochastic processes. On the other hand, quasi-periodic oscillation (QPO) behaviors are recently reported to be detected in $\it{Fermi}$-LAT data of blazars. However, the significances of these QPO signals given by traditional Fourier-like methods are still questioned. We analyze $γ$-ray light curves of the QPO blazars with two Gaussian process methods, CARMA and $\it{celerite}$, to examine the appropriateness of Gaussian processes for characterizing $γ$-ray light curves of blazars and the existence of the reported QPOs. We collect a sample of 27 blazars with possible $γ$-ray periodicity and generate their $\sim11$ years $\it{Fermi}$-LAT light curves. We apply the Gaussian process models to the $γ$-ray light curves, and build their intrinsic power spectral densities (PSDs). The results show that in general the $γ$-ray light curves can be characterized by CARMA and $\textit{celerite}$ models, indicating that $γ$-ray variabilities of blazars are essentially Gaussian processes. The resulting PSDs are generally the red noise shapes with slopes between $-0.6$ and $-1.7$. Possible evidence for the $γ$-ray QPOs in PKS 0537$-$441 and PG 1553$+$113 are found in the Gaussian process modelings.

In this paper, we will show an index theorem in the TP monopole background, which is defined in the projected space, and provide a meaning of the projection operator. We also extend the index theorem to general configurations which do not satisfy the equation of motion, and show that the configuration space can be classified into the topological sectors. We further calculate the spectrum of the GW Dirac operator in the TP monopole backgrounds, and consider the index theorem in these cases.

description: I propose a method to detect planets around compact binaries that are strong sources of gravitational radiation. This approach is to measure gravitational-wave phase modulations induced by the planets, and its prospect is studied with a Fisher matrix analysis. I find that, using the Laser Interferometer Space Antenna (LISA), planets can be searched for around ~3000 Galactic double white dwarfs with detection limit ~4 M_J (M_J~ 2x10^{30}g: the Jupiter mass). With its follow-on missions, planets with mass ~1 M_J might be detected around double neutron stars even at cosmological distances z~1. In this manner, gravitational wave observation has potential to make interesting contributions to extra-solar planetary science.

description: Big Bang nucleosynthesis produces only light elements and the very first generation stars are thus formed from metal-free clouds. They start the production of heavy elements during their life, and enrich the interstellar medium through their explosive death. Stellar evolution models show that the treatment of rotation has important effects on the evolution of those metal-free stars: for example, rotating models produce up to five orders of magnitude more primary nitrogen than non rotating models, due to internal mixing. This will have an impact in the composition of the second generation stars, some of which may now be observed in the Galactic halo. In the case Population III stars were very massive and would end up as direct black holes, rotation again have an interesting effect of enhancing mass loss through centrifugal force and surface enrichment. CNO composition patterns observed in ultra metal-poor halo stars may be explained by a 'wind only' contribution.

Multiple Rings in the Shadow of Extremely Compact Objects

description: The Event Horizon Telescope's image of the M87 black hole provides an exciting opportunity to study black hole physics. Since a black hole's event horizon absorbs all electromagnetic waves, it is difficult to actively probe the horizon's existence. However, with the help of a family of extremely compact, horizon-less objects, named gravastars", whose external space-times nearly identical to those of black holes, one can test the absence of event horizons: absences of additional features that arise due to the existence of the gravastar, or its surface, can be used as quantitative evidence for black holes. We apply Gralla et al.'s approach to studying black hole images to study the images of two types of gravastars: transparent ones and reflective ones. In both cases, the transmission of rays through gravastars, or their reflections on their surfaces, lead to more rings in their images. For simple emission models, where the redshifted emissivity of the disk is peaked at a particular radius r-peak, the position of a series of rings can be related in a simple manner to light ray propagation: a ring shows up around impact parameter b whenever rays incident from infinity at b intersects the disk at r-peak. We show that additional rings will appear in the images of transparent and reflective gravastars. In particular, one of the additional rings for the reflective gravastar is due to the prompt reflection of light on the gravastar surface and appears to be well separated from the others. This can be a robust feature, which may be reliably used to constrain the reflectivity of the black hole's horizon.

We deduce a variety of spectral gap theorems in complex Banach spaces. We prove a dominated complex cone-contraction Theorem and use it to extend the classical Perron-Frobenius Theorem to complex matrices, Jentzsch's Theorem to complex integral operators, a Krein-Rutman Theorem to compact and quasi-compact complex operators and a Ruelle-Perron-Frobenius Theorem to complex transfer operators in dynamical systems. In the simplest case of a complex n by n matrix A we have the following statement: Suppose that 0 < c < +infinity is such that |Im A_{ij} \bar{A}_{mn}| < c < Re A_{ij} \bar{A}_{mn} for all indices. Then A has a `spectral gap'.

description: The aim of this study is to generate maps of the hard X-ray emission produced by energetic electrons in a solar flare and compare them with observations. The ultimate goal is to test the viability of the combined MHD/test-particle approach for data-driven modelling of active events in the solar corona and their impact on the heliosphere. Based on an MHD model of X-class solar flare observed on the 8th of September 2017, we calculate trajectories of a large number of electrons and protons using the relativistic guiding-centre approach. Using the obtained particle trajectories, we deduce the spatial and energy distributions of energetic electrons and protons, and calculate bremsstrahlung hard X-ray emission using the 'thin target' approximation. Our approach predicts some key characteristics of energetic particles in the considered flare, including the size and location of the acceleration region, energetic particle trajectories and energy spectra. Most importantly, the hard X-ray bremsstrahlung intensity maps predicted by the model are in a good agreement with those observed by RHESSI. Furthermore, the locations of proton and electron precipitation appear to be close to the sources of helioseismic response detected in this flare. Therefore, the adopted approach can be used for observationally-driven modelling of individual solar flares, including manifestations of energetic particles in the corona, as well as inner heliosphere.

Responses of coyotes and lynx to the snowshoe hare cycle

Publisher: name: University of British Columbia

description: Coyotes and lynx are the two most important mammalian predators of snowshoe hares throughout much of the boreal forest. Populations of hares cycle in abundance, with peaks in density occurring every 8-11 years, and experimental results suggest that predation is a necessary factor causing these cycles. We measured the numerical and functional responses of coyotes and lynx during a cyclic fluctuation of hare populations in the southwest Yukon, to determine their effect on the cyclic dynamics. We used snow-tracking, track counts, and radio telemetry to directly examine changes in the numbers, population dynamics, and foraging behaviour of the predators. Numbers of coyotes varied 6-fold and those of lynx 7.5-fold during a 26-44-fold fluctuation in numbers of hares, and the abundances of both predators were maximal a year later than the peak in numbers of snowshoe hares. Cyclic declines in numbers of coyotes and lynx were associated with lower reproductive output and high dispersal rates, and low in situ survival of lynx later in the decline. Coyotes and lynx both fed mostly on hares during all winters except during cyclic lows, when the main alternative prey of coyotes was voles, and lynx switched to hunting red squirrels. Both predators showed clear functional responses to changes in the densities of hares. Kill rates of hares by coyotes varied from 0.3 to 2.3 hares/day, with the most hares killed one year before the cyclic peak, while those of lynx varied from 0.3 to 1.2 hares/day, with the highest one year after the peak. Coyotes killed more hares early in the winter, and cached many of these for later retrieval. Based on these estimates, the combined effect of predation by coyotes and lynx ranged from 9.1% to 46.5% of the total winter population of hares killed. There were several changes in foraging behaviour of the predators over the cycle. Habitat use by coyotes and lynx varied, and roughly paralleled trends in habitats used by hares. Lynx increasingly used hunting beds for ambushing both hares and red squirrels during the cyclic decline and low. Lynx also hunted in adult groups for the first time during the decline and low in hare numbers.

description: Comparing the asymmetry coefficients and scintillation indices for observed time variations of the intensity of the radiation of extragalactic sources and the predictions of theoretical models is a good test of the nature of the observed variations. Such comparisons can be used to determine whether flux-density variations are due to scintillation in the interstellar medium or are intrinsic to the source. In the former case, they can be used to estimate the fraction of the total flux contributed by the compact component (core) whose flux-density variations are brought about by inhomogeneities in the interstellar plasma. Results for the radio sources PKS 0405-385, B0917+624, PKS 1257-336, and J1819+3845 demonstrate that the scintillating component in these objects makes up from 50% to 100% of the total flux, and that the intrinsic angular sizes of the sources at 5 GHz is 10-40 microarcseconds. The characteristics of the medium giving rise to the scintillations are presented.

description: We introduce the out-of-time-correlation(OTOC) with the Planck cell resolution. The dependence of this OTOC on the initial state makes it function like a microscope, allowing us to investigate the fine structure of quantum dynamics beyond the thermal state. We find an explicit relation of this OTOC to the spreading of the wave function in the Hilbert space, unifying two branches of the study of quantum chaos: state evolution and operator dynamics. By analyzing it in the vicinity of the classical limit, we clarify the dependence of the OTOC's exponential growth on the classical Lyapunov exponent.

description: The structural evolution of a nano-powder by repeated dispersion and settling can lead to characteristic fractal substructures. This is shown by numerical simulations of a two-dimensional model agglomerate of adhesive rigid particles. The agglomerate is cut into fragments of a characteristic size l, which then are settling under gravity. Repeating this procedure converges to a loosely packed structure, the properties of which are investigated: a) The final packing density is independent of the initialization, b) the short-range correlation function is independent of the fragment size, c) the structure is fractal up to the fragmentation scale l with a fractal dimension close to 1.7, and d) the relaxation time increases linearly with l.

Regulation of rat ovarian gonadotropin Releasing hormone receptor mRNA levels
Creators: name: Väänänen, Céline Claire Magali
Publisher: name: University of British Columbia
Year: 2009

description: The studies undertaken herewithin sought to characterize the pattern of regulation of the gonadotrophin-releasing hormone receptor (GnRH-R) mRNA levels in the rat ovary. The demonstration of gonadotrophin-releasing hormone (GnRH) transcripts in steroidproducing and steroid-dependent tissues suggests that GnRH may be implicated in the modulation of steroid action in those target tissues. Expression of GnRH-R mRNA increases in gonadal tissues and the pituitary with age, supporting the concept of GnRH as a local regulator in the developing rat as well as in the adult. During the peri-ovulatory period, stimulation of the ovarian luteinizing hormone receptor (LH-R) by an ovulatory dose of human chorionic gonadotrophin (hCG) is capable of inducing a transient and pronounced decrease in GnRH-R mRNA levels, thus bringing more evidence to the role of GnRH in the regulation of ovarian function during ovulation. The gene encoding GnRH-R was found to be expressed in granulosa cells. In a follicle stimulating hormone (FSH) pre-treated granulosa cell model, GnRH-R gene transcript levels were negatively influenced by LH, but not FSH, in a time- and concentration-dependent manner. Autostimulation of GnRH-R by GnRH was also seen. In a second granulosa cell model obtained from pregnant mare serum gonadotrophin (PMSG) synchronized immature rats, the levels of GnRH-R transcripts were found to be positively regulated by hCG and GnRH, while prostaglandin F2a (PGF20;) inhibited GnRH-R mRNA levels in a bell curve-like fashion. However, combinations of these treatments canceled each other's effects. In this model, GnRH stimulated progesterone (P4) production and only slightly inhibited hCG-stimulated progesterone production. This modulation in the responses to GnRH and in the levels of GnRH-R mRNA suggest that GnRH may have different actions at different times of follicular development. In conclusion, the findings of the present study demonstrate wide spread expression of the GnRH-R gene in steroidogenic or steroid-dependent tissues. Gonadotrophin-releasing hormone receptor mRNA levels were shown to be regulated by gonadotrophins, PGF2a and GnRH in the whole ovary and in granulosa cells, strongly supporting the postulated role of GnRH-R in the local modulations of ovarian function mediated by GnRH.

description: The first- and second-order correlation functions of trapped, interacting Bose-Einstein condensates are investigated numerically on a many-body level from first principles. Correlations in real space and momentum space are treated. The coherence properties are analyzed. The results are obtained by solving the many-body Schrödinger equation. It is shown in an example how many-body effects can be induced by the trap geometry. A generic fragmentation scenario of a condensate is considered. The correlation functions are discussed along a pathway from a single condensate to a fragmented condensate. It is shown that strong correlations can arise from the geometry of the trap, even at weak interaction strengths. The natural orbitals and natural geminals of the system are obtained and discussed. It is shown how the fragmentation of the condensate can be understood in terms of its natural geminals. The many-body results are compared to those of mean-field theory. The best solution within mean-field theory is obtained. The limits in which mean-field theories are valid are determined. In these limits the behavior of the correlation functions is explained within an analytical model.
