description: For classical fault analysis, a transient fault is required to be injected during runtime, e.g., only at a specific round. Instead, Persistent Fault Analysis (PFA) introduces a powerful class of fault attacks that allows for a fault to be present throughout the whole execution. One limitation of original PFA as introduced by Zhang et al. at CHES'18 is that the faulty values need to be known to the adversary. While this was addressed at a follow-up work at CHES'20, the solution is only applicable to a single faulty value. Instead, we use the potency of Statistical Fault Analysis (SFA) in the persistent fault setting, presenting Statistical Persistent Fault Analysis (SPFA) as a more general approach of PFA. As a result, any or even a multitude of unknown faults that cause an exploitable bias in the targeted round can be used to recover the cipher's secret key. Indeed, the undesired faults in the other rounds that occur due the persistent nature of the attack converge to a uniform distribution as required by SFA. We verify the effectiveness of our attack against LED and AES.

description: For even dimensional conformal manifolds several new conformally invariant objects were found recently: invariant differential complexes related to, but distinct from, the de Rham complex (these are elliptic in the case of Riemannian signature); the cohomology spaces of these; conformally stable form spaces that we may view as spaces of conformal harmonics; operators that generalise Branson's Q-curvature; global pairings between differential form bundles that descend to cohomology pairings. Here we show that these operators, spaces, and the theory underlying them, simplify significantly on conformally Einstein manifolds. We give explicit formulae for all the operators concerned. The null spaces for these, the conformal harmonics, and the cohomology spaces are expressed explicitly in terms of direct sums of subspaces of eigenspaces of the form Laplacian. For the case of non-Ricci flat spaces this applies in all signatures and without topological restrictions. In the case of Riemannian signature and compact manifolds, this leads to new results on the global invariant pairings, including for the integral of Q-curvature against the null space of the dimensional order conformal Laplacian of Graham et al..

description: No abstracts are to be cited without prior reference to the author.This study aims to evaluate the effect on acoustic surveys of the change in the area sampled by an echosounder beam down through the water column. The area sampled by a single beam echosounder with a moderately narrow beam angle is frequently a very small sample of the total survey area at shallow ranges, although, with increasing range, the sampled area increases geometrically. The depth at which the sampled volumes begin to overlap is influenced by the ship's speed and the ping rate, and the selection of these two parameters has been studied in order to find out how to make optimum use of the available survey time.

description: This paper is connected with the problem of describing path metric spaces that are homeomorphic to manifolds and biLipschitz homogeneous, i.e., whose biLipschitz homeomorphism group acts transitively. Our main result is the following. Let $X = G/H$ be a homogeneous manifold of a Lie group $G$ and let $d$ be a geodesic distance on $X$ inducing the same topology. Suppose there exists a subgroup $G_S$ of $G$ that acts transitively on $X$, such that each element $g \in G_S$ induces a locally biLipschitz homeomorphism of the metric space $(X,d)$. Then the metric is locally biLipschitz equivalent to a sub-Riemannian metric. Any such metric is defined by a bracket generating $G_S$-invariant sub-bundle of the tangent bundle. The result is a consequence of a more general fact that requires a transitive family of uniformly biLipschitz diffeomorphisms with a control on their differentials. It will be relevant that the group acting transitively on the space is a Lie group and so it is locally compact, since, in general, the whole group of biLipschitz maps, unlikely the isometry group, is not locally compact. Our method also gives an elementary proof of the following fact. Given a Lipschitz sub-bundle of the tangent bundle of a Finsler manifold, then both the class of piecewise differentiable curves tangent to the sub-bundle and the class of Lipschitz curves almost everywhere tangent to the sub-bundle give rise to the same Finsler-Carnot-Carathéodory metric, under the condition that the topologies induced by these distances coincide with the manifold topology.

It is shown to give the correct equilibrium statistics and is then used to investigate nonequilibrium phenomena, in particular, magnetic avalanches. The value of damping can greatly alter the shape of hysteresis loops, and for small damping and high disorder, the morphology of large avalanches can be drastically effected. Small damping also alters the size distribution of avalanches at criticality.

Six-dimensional matching of intense beam with linear accelerating structure

description: Beam matching is a common technique that is routinely employed in accelerator design with the aim of minimizing beam losses and preservation of beam brightness. Despite being widely used, a full theoretical understanding of beam matching in 6D remains elusive. Here, we present an analytical treatment of 6D beam matching of a high-intensity beam onto an RF structure. We begin our analysis within the framework of a linear model, and apply the averaging method to a set of 3D beam envelope equations. Accordingly, we obtain a matched solution that is comprised of smoothed envelopes and periodic terms, describing envelope oscillations with the period of the focusing structure. We then consider the nonlinear regime, where the beam size is comparable with the separatrix size. Stating with a Hamiltonian analysis in 6D phase space, we attain a self-consistent beam profile and show that it is significantly different from the commonly used ellipsoidal shape. Subsequently, we analyze the special case of an equilibrium with equal space charge depression between all degrees of freedom. Comparison of beam dynamics for equipartitioned, equal space charge depression, and equal emittances beams is given. Finally, we present experimental results on beam matching in the LANSCE linac.

description: We study the minimum backlog problem (MBP). This online problem arises, e.g., in the context of sensor networks. We focus on two main variants of MBP. The discrete MBP is a 2-person game played on a graph $G=(V,E)$. The player is initially located at a vertex of the graph. In each time step, the adversary pours a total of one unit of water into cups that are located on the vertices of the graph, arbitrarily distributing the water among the cups. The player then moves from her current vertex to an adjacent vertex and empties the cup at that vertex. The player's objective is to minimize the backlog, i.e., the maximum amount of water in any cup at any time. The geometric MBP is a continuous-time version of the MBP: the cups are points in the two-dimensional plane, the adversary pours water continuously at a constant rate, and the player moves in the plane with unit speed. Again, the player's objective is to minimize the backlog. We show that the competitive ratio of any algorithm for the MBP has a lower bound of $Ω(D)$, where $D$ is the diameter of the graph (for the discrete MBP) or the diameter of the point set (for the geometric MBP). Therefore we focus on determining a strategy for the player that guarantees a uniform upper bound on the absolute value of the backlog. For the absolute value of the backlog there is a trivial lower bound of $Ω(D)$, and the deamortization analysis of Dietz and Sleator gives an upper bound of $O(D\log N)$ for $N$ cups. Our main result is a tight upper bound for the geometric MBP: we show that there is a strategy for the player that guarantees a backlog of $O(D)$, independently of the number of cups.

description: In this paper, it is emphasized that the dynamical cause for the A-B effect is the superimposed energy between the magnetic field produced by the moving charges and that in the solenoid, instead of the existence of the vector potential. If such a superposition between the magnetic fields can be eliminated, the A-B effect should not be observed any more. To verify this viewpoint, a new experimental method using a SQUID is suggested in this paper.

Development of empirical rib pillar design criterion for open stope mining
Creators: name: Hudyma, Martin Raymond
Publisher: name: University of British Columbia
Year: 2010

description: The design of open stope rib pillars has been done using many empirical methods, but none of the methods has been verified with a design survey. This thesis uses data collected in the "Integrated Mine Design Study" to develop an empirical rib pillar design method for open, stope mining. The method is called the "pillar stability graph". The design variables in the method are: the compressive strength of the intact pillar material, the average pillar load determined by numerical modelling, the pillar width and the pillar height. The graph has been refined with the use of more than 80 literature case histories of hard rock pillars in room and pillar mining. The pillar stability graph and the pillar data base are used to examine the applicability of empirical methods commonly used in open stope rib pillar design. The investigation found the pillar strength curves developed by Hoek and Brown (1980) may be useful under some conditions for the design of open stope rib pillars but formulas by Hedley (1972), Obert and Duvall (1967) and Bieniawski (1983) are not applicable. Guidelines, using the pillar stability graph method, are proposed for the design of permanent open stope rib pillars, stable temporary open stope rib pillars, and failing temporary open stope rib pillars.

Year: 2024

description: The ongoing decline of public support for democracy and the growing support for less democratic alternatives in Latin America relate to escalating sociopolitical tensions in the region. These tensions are evidenced in the rise of protests and social mobilization. In Latin America, different manifestations of social discontent include peaceful protests as well as more violent social mobilization. In this article it is argued that the rise of both peaceful and violent protests in the region are related to the nature of the political systems in place in each country and the institutional capacity of each individual Government to resolve social tensions.

description: No abstracts are to be cited without prior reference to the author.Schools of horse mackerel (Trachurus trachurus capensis), pilchard (Sardinops sagax) and round herring (.Etrumeus whiteheadi) were surveyed by conventional echo integration along systematic transects. The survey transects were steamed twice in opposite directions. The biomass of clupeoids was concentrated in a few, dense aggregations, while horse mackerel was distributed in looser concentrations over larger areas. The influence of the aggregation pattern of the different species on the precision of the acoustic estimates was analyzed with respect to spatial variability -and diurnal effects. The replicability of acoustic survey estimates was considered on the basis of the two coverages of the area surveyed. The importance of survey design was emphasized when estimating the biomass of highly aggregated pelagic stocks.

With the exception of Hubble V, the young cluster in NGC 205, we find that these young clusters have kinematics and spatial distribution consistent with membership in M31's young disk. Preliminary estimates of the cluster masses and structural parameters, using spectroscopically derived ages and HST imaging, confirms earlier suggestions that M31 has clusters similar to the LMC's young populous clusters.

description: Peptide and protein nanocluster vaccines represent cutting-edge advancements in immunization technology. These vaccines utilize nanotechnology to effectively deliver antigens, enhancing immune responses while tackling the challenges associated with conventional vaccines, including issues related to storage, scalability, and effectiveness against swiftly evolving pathogens. They provide adaptable solutions for a variety of diseases, including COVID-19, tuberculosis, influenza, and cancer. This innovative strategy, which involves self-assembling protein nanoparticles, peptide-based vaccines, capsid-like particles, and protein-conjugate vaccines, showcases significant benefits such as enhanced antigen presentation, wide-ranging applicability, and the potential for scalable production. Nevertheless, obstacles like high research and development costs, complex regulatory requirements, and vaccine hesitancy need to be addressed to fully realize their potential.

description: We calculate the quantum radiation power of black holes which are asymptotic to the Einstein-de Sitter universe at spatial and null infinities. We consider two limiting mass accretion scenarios, no accretion and significant accretion. We find that the radiation power strongly depends on not only the asymptotic condition but also the mass accretion scenario. For the no accretion case, we consider the Einstein-Straus solution, where a black hole of constant mass resides in the dust Friedmann universe. We find negative cosmological correction besides the expected redshift factor. This is given in terms of the cubic root of ratio in size of the black hole to the cosmological horizon, so that it is currently of order $10^{-5} (M/10^{6}M_{\odot})^{1/3} (t/14 {Gyr})^{-1/3}$ but could have been significant at the formation epoch of primordial black holes. Due to the cosmological effects, this black hole has not settled down to an equilibrium state. This cosmological correction may be interpreted in an analogy with the radiation from a moving mirror in a flat spacetime. For the significant accretion case, we consider the Sultana-Dyer solution, where a black hole tends to increase its mass in proportion to the cosmological scale factor. In this model, we find that the radiation power is apparently the same as the Hawking radiation from the Schwarzschild black hole of which mass is that of the growing mass at each moment. Hence, the energy loss rate decreases and tends to vanish as time proceeds. Consequently, the energy loss due to evaporation is insignificant compared to huge mass accretion onto the black hole. Based on this model, we propose a definition of quasi-equilibrium temperature for general conformal stationary black holes.

description: Mixed initiative in open-domain dialogue requires a system to pro-actively introduce new topics. The one-turn topic transition task explores how a system connects two topics in a cooperative and coherent manner. The goal of the task is to generate a "bridging" utterance connecting the new topic to the topic of the previous conversation turn. We are especially interested in commonsense explanations of how a new topic relates to what has been mentioned before. We first collect a new dataset of human one-turn topic transitions, which we call OTTers. We then explore different strategies used by humans when asked to complete such a task, and notice that the use of a bridging utterance to connect the two topics is the approach used the most. We finally show how existing state-of-the-art text generation models can be adapted to this task and examine the performance of these baselines on different splits of the OTTers data.

description: The BL Lac object (blazar) Mrk 421 was observed during its outburst in April 2004 with the Whipple 10 m telescope for a total of about 24.5 hours. The measured gamma-ray rate varied substantially over the range from 4 to 10 gamma's/min and eventually exceeded the steady gamma-ray rate of the Crab Nebula (standard candle) by a factor of 3. The overall significance of the gamma-ray signal exceeded 70 sigma and the total number of excess events was more than 10,000. The signal light curve does not show any particular variability pattern. This unique Mrk 421 outburst enabled the measurement of a high quality spectrum of very high-energy gamma rays in a high state of emission. This spectrum is a power-law and it extends beyond 10 TeV.

description: We present initial results of a 750 ks Chandra observation of the remnant of Kepler's supernova of AD 1604. The strength and prominence of iron emission, together with the absence of O-rich ejecta, demonstrate that Kepler resulted from a thermonuclear supernova, even though evidence for circumstellar interaction is also strong. We have analyzed spectra of over 100 small regions, and find that they fall into three classes. (1) The vast majority show Fe L emission between 0.7 and 1 keV and Si and S K alpha emission; we associate these with shocked ejecta. A few of these are found at or beyond the mean blast wave radius. (2) A very few regions show solar O/Fe abundance rations; these we associate with shocked circumstellar medium (CSM). Otherwise O is scarce. (3) A few regions are dominated by continuum, probably synchrotron radiation. Finally, we find no central point source, with a limit about 100 times fainter than the central object in Cas A. The evidence that the blast wave is interacting with CSM may indicate a Ia explosion in a more massive progenitor.

description: No abstracts are to be cited without prior reference to the author.Presently the Norwegian spring spawning herring utilises spawning grounds along the Norwegian coast from Lofoten in the north (69°N) to Lista in the south (57°N), and the spawning migration originates from the wintering area in Vestfjorden, northern Norway (68°N), in mid January. This paper is based on acoustical data of herring collected during the spawning season (February-March) in the 1990s. The herring occurred in different types of aggregations influenced by the stage of maturity (maturing, ripe, spawning, spent) and by external factors like ambient illumination (daylight/darkness), fish density within the area and bottom depth. Different aggregation patterns were also observed to the north and south of 62°N. The behavioural mechanisms leading to the differences in aggregation are discussed.

description: No abstracts are to be cited without prior reference to the author.There are two independent fisheries targeted on mackerel (Scomber japonicus) off the argentine coast. Both fisheries take place off the Buenos Aires province coast and have distinct characteristics of exploitation, targeting on presumed different fish stocks. This paper summarizes the present knowledge about the aggregation strategies of the mackerel schools observed for both areas, yet with special reference to the so called marplatense fisheries, and its relationships with the environmental conditions.

description: No abstracts are to be cited without prior reference to the author.Cusk eel, Ophidion holbrooki, occurs as by-Qltch in the pink shrimp fishery of Southeastern Brazil (23° to 27° S). Studies conducted from 1987 to 1991 had shown that spawning takes place mainly on late summer, maybe favoured by the penetration of a cold water mass over the shelf responsible to disperse the benthic eggs and early larval stages and to the relatively seasonal variability of spawnning. Females are smaller than males, contradicting literature on genus. Dominance seemed size and sexual dependant; a sexual segregation was shown over the year (except on spawning period). Geographical distribution range is associated to sediments (muddy patches) required for burrowing behaviour. Depending of the strength of water masses penetration, these areas maybe bigger or smaller, affecting the population structure, which appear to be denso-dependent. Feeding behaviour of the species is unknown, but considering the similarity to other species from the genus (as shown by food analysis) it would be explained the ontogenetical segregation observed. Growth parameters based on length frequency distributions were k=0.3764; L.,=356.97 mm; t,=-0.022. Mortality estimated by various methods varied from 0.4 to 0.68 for Mand 1.57 to 1.87 to F. Preliminary stock assessment analysis suggested that population is not nnder risk of overfishing, probably due to the onto genetic segregation ( considering the cannibalism common to the family).

description: No abstracts are to be cited without prior reference to the author.Populations of endangered salmonids in the nature are very sparce. Hatchery broodstocks are usually founded- by catching mature fish before or at the spawning time and the rearing of a new broodstock is started by mating of these fish. The number of individuals used as founders and the mating procedure determine the limits for possible genetic structure and variability of a broodstock. Incubation of fertilized eggs and subsequent rearing of juveniles may strongly affect the genetic structure and variability achieved at the maturity of each broodstock.

description: A significant obstacle for practical quantum computation is the loss of physical qubits in quantum computers, a decoherence mechanism most notably in optical systems. Here we experimentally demonstrate, both in the quantum circuit model and in the one-way quantum computer model, the smallest non-trivial quantum codes to tackle this problem. In the experiment, we encode single-qubit input states into highly-entangled multiparticle codewords, and we test their ability to protect encoded quantum information from detected one-qubit loss error. Our results prove the in-principle feasibility of overcoming the qubit loss error by quantum codes.

Numerical analysis of rock failure and laboratory study of the related acoustic emission
Creators: name: Zou, Daihu
Publisher: name: University of British Columbia

description: Sudden rock failure in the form of rockbursting has long been a problem in underground mines. The basic mechanism of this phenomenon is still unresolved. This thesis describes the research work on this problem conducted by the doctoral candidate Daihua Zou in the Department of Mining and Mineral Process Engineering at The University of British Columbia, under the supervision of Professor Hamish D.S. Miller. This research project was undertaken in order to investigate the process of violent rock failure and was achieved by examining various aspects of the rock failure mechanism. The assumption that acoustic emission can be used as a reliable means of predicting rock failure was investigated, as well as the possibility that violent rock failure could occur in any mine rock. As part of the research, a rock failure mechanism was postulated. A process analogous to shearing is postulated to be important at the post-failure stage. The stick-slip phenomenon has been analyzed using a numerical model under a variety of conditions. The conditions which could give rise to possible violent rock failure were determined. At the same time, acoustic emissions were tested from rock specimens under different loading conditions. The experimental results obtained show a correlation with field measurements made in a mine. In order to verify the testing results from limited experiments, a numerical acoustic model was developed, which is unique in that it is entirely based on the stick-slip process not on any acoustic theory. This model allows rock tests and their associated acoustic emission to be realistically simulated. With this model, acoustic emissions were simulated under various loading conditions for different kinds of rocks. The case of a hard or a soft intercalation was also modelled.

description: No abstracts are to be cited without prior reference to the author.Genetic structure of the mussel (M. trossulus) populations from different sites along Polish Baltic coast with the application of mitochondrial DNA (mtDNA) was studied. Heteroplasmy (presence of two mtDNA types in a specimen) was further investigated. In comparison with other animal species, doubly uniparental inheritance ofmtDNA is a characteristic feature in the marine mussels. Additionally to mitochondrial genome inherited through female line, heteroplasmic specimens contain a second genome, inherited through male line. Differences among populations were detected by restriction analysis of PCR amplified coding region (ND2-COIII) of 1.3 kb size. Significant differences in haplotype frequences among populations from the Gulf of Gdansk and open sea coast were observed. Length variants were identified through PCR amplification of the majon noncoding region of mtDNA. 14 length variants present in homo-and heteroplasmic specimens were found. Two length variants were more common than others in mussel populations. A comparison of length variants with haplotype polymorphism revealed by restriction analysis of the coding region was made. It is expected that the length variants are inherited through male and female lineages.

description: Popular musicians are embedded in dynamic networks supporting their expertise development across different phases. During these phases, network actors support different aspects of deliberate practice in which a musician needs to engage to become an expert. Research in the domain of music is scarce in terms of investigating the change in the supportive networks of deliberate practice over time. Semi-structured interviews with five expert and five intermediate popular musicians were used to explore changes in networks supporting the deliberate practice during their childhood, apprenticeship, and career phases. Egocentric network analysis revealed that networks supporting the deliberate practice of expert musicians are more dynamic and less stable when considering the different phases than the networks of intermediates. In addition, experts are supported by a larger number of network actors during the developmental phases. In both groups, the number of network actors decreased as the musicians progressed through the phases. This decrease was more precipitous between the childhood and apprenticeship phases. Overall, expertise development as a popular musician depends not only on deliberate practice but also on the diversity and change in an adaptive support network from childhood to adulthood.

description: We report on a search for pulsars at the positions of eight low-mass white dwarfs and one higher-mass white dwarf with the 100-m Effelsberg Radio Telescope. These systems have orbital parameters suggesting that their unseen companions are either massive white dwarfs or neutron stars. Our observations were performed at 1.36 GHz, reaching sensitivities of 0.1-0.2 mJy. We searched our data accounting for the possible acceleration and jerk of the pulsar signals due to orbital motion, but found no significant pulsar signals. Considering our result jointly with 20 non-detections of similar systems with the Greenbank Radio Telescope, we infer $f_{\rm NS}\leq 0.10$, for the fraction of NSs orbiting these white dwarfs. We discuss the sensitivity of this result to the underlying assumptions and conclude with a brief discussion on the prospects of targeted surveys for discovering millisecond pulsars.

description: For a fixed integer h>=1, let G be a tripartite graph with N vertices in each vertex class, N divisible by 6h, such that every vertex is adjacent to at least 2N/3+h-1 vertices in each of the other classes. We show that if N is sufficiently large, then G can be tiled perfectly by copies of K_{h,h,h}. This extends the work in [19] and also gives a sufficient condition for tiling by any (fixed) 3-colorable graph. Furthermore, we show that this minimum-degree condition is best possible and provide very tight bounds when N is divisible by h but not by 6h.
