description: Tight-binding molecular dynamics simulations shed light into the fracture mechanisms and the ideal strength of tetrahedral amorphous carbon and of nanocomposite carbon containing diamond crystallites, two of the hardest materials. It is found that fracture in the nanocomposites, under tensile or shear load, occurs inter-grain and so their ideal strength is similar to the pure amorphous phase. The onset of fracture takes place at weakly bonded sp^3 sites in the amorphous matrix. On the other hand, the nanodiamond inclusions significantly enhance the elastic moduli, which approach those of diamond.

description: The high energy beam transport (HEBT) line for the ISAC radioactive beam facility at TRIUMF requires an 11.8 MHz buncher. The main requirements of the buncher are to operate in cw mode with a velocity acceptance of 2.2% and an effective voltage of 100 kV, which for a three gap buncher gives a drift tube voltage of 30 kV. A lumped element circuit is more suitable than a distributed rf structure for this low frequency of operation. The resonant frequency of 11.8 MHz is obtained by an inductive coil in parallel with the capacitance of the drift tube. The coil is housed in a dust free box at atmospheric pressure whereas the drift tube is placed in a vacuum chamber and an rf feedthrough connects them. Two design of this feedthrough, one using disk and one using tubular ceramics, operating at 30 kV rf, are described in this paper. MAFIA and SUPERFISH codes are used to simulate the fields in the feedthroughs, particularly around the ceramic metal interfaces. Test results of the prototype feedthroughs are presented and the choice of the proposed final solution is outlined.

Feeding the exceptionally high producing dairy cow
Creators: name: Staubus, John R.
Publisher: name: The Bovine Practitioner
Year: 1986

description: The goal of every dairy herdsman should be to provide the right amount of feed for the right cow at the right time. This should maximize profits while minimizing metabolic problems. The most difficult problem is to change the feeding program of cows from that which meets the needs of dry cows to a program that meets the needs of cows producing at very high levels.

description: We analyzed the ~950 ks of spectroscopic data accumulated by the Extreme Ultraviolet Explorer (EUVE) satellite between 1994 and 1997 for the BL Lacertae object Markarian 421. The EUV spectrum is well detected in the 70-110 A (112-177 eV) range and can be fitted by a power law model plus an absorption feature in the ~71-75 A range. Previous studies of EUV absorption features in MRK 421 and in the other EUV bright BL Lac object, PKS2155-304, explain this absorption feature as a superposition of Doppler-smeared absorption lines (mainly L- and M-shell transitions of Mg and Ne) originating in high-velocity gas clouds ionized by the beamed continuum of the associated relativistic jet. We show that, for example, Fe IX L could also be a possibility consistent with the marginal detection of oxygen absorption lines in the X-ray range. However physical models are highly sensitive to the assumptions on the photoionizing continuum and the surrounding gas.

description: In this letter, we present the frequency dependence of the vortex surface resistance of bulk niobium accelerating cavities as a function of different state-of-the-art surface treatments. Higher flux surface resistance per amount of trapped magnetic field - sensitivity - is observed for higher frequencies, in agreement with our theoretical model. Higher sensitivity is observed for N-doped cavities, which possess an intermediate value of electron mean-free-path, compared to 120 C and EP/BCP cavities. Experimental results from our study showed that the sensitivity has a non-monotonic trend as a function of the mean-free-path, including at frequencies other than 1.3 GHz, and that the vortex response to the rf field can be tuned from the pinning regime to flux-flow regime by manipulating the frequency and/or the mean-free-path of the resonator, as reported in our previous studies. The frequency dependence of the trapped flux sensitivity to the amplitude of the accelerating gradient is also highlighted.

description: We propose a framework to generate alternative mixed-integer nonlinear programming formulations for disjunctive convex programs that lead to stronger relaxations. We extend the concept of “basic steps” defined for disjunctive linear programs to the nonlinear case. A basic step is an operation that takes a disjunctive set to another with fewer number of conjuncts. We show that the strength of the relaxations increases as the number of conjuncts decreases, leading to a hierarchy of relaxations. We prove that the tightest of these relaxations, allows in theory the solution of the disjunctive convex program as a nonlinear programming problem. We present a methodology to guide the generation of strong relaxations without incurring an exponential increase of the size of the reformulated mixed-integer program. Finally, we apply the theory developed to improve the computational efficiency of solution methods for nonlinear convex generalized disjunctive programs (GDP). This methodology is validated through a set of numerical examples.

description: It is a pleasure for me to be part of this program on nutrition and nutritional diseases in food animals. Although my formal education was in animal nutrition, it has been very difficult to keep up with new advances. In fact, it has been difficult to maintain a working knowledge in amino acid nutrition, an area I spent many years researching. Therefore, I intend to listen attentively to what is said by others from this podium.

description: This short empirical paper investigates how well topic modeling and database meta-data characteristics can classify web and other proof-of-concept (PoC) exploits for publicly disclosed software vulnerabilities. By using a dataset comprised of over 36 thousand PoC exploits, near a 0.9 accuracy rate is obtained in the empirical experiment. Text mining and topic modeling are a significant boost factor behind this classification performance. In addition to these empirical results, the paper contributes to the research tradition of enhancing software vulnerability information with text mining, providing also a few scholarly observations about the potential for semi-automatic classification of exploits in the existing tracking infrastructures.

Zitterbewegung of nearly-free and tightly bound electrons in solids

Year: 2006

description: We show theoretically that nonrelativistic nearly-free electrons in solids should experience a trembling motion (Zitterbewegung, ZB) in absence of external fields, similarly to relativistic electrons in vacuum. The Zitterbewegung is directly related to the influence of periodic potential on the free electron motion. The frequency of ZB is $ω\approx E_g/\hbar$, where $E_g$ is the energy gap. The amplitude of ZB is determined by the strength of periodic potential and the lattice period and it can be of the order of nanometers. We show that the amplitude of ZB does not depend much on the width of the wave packet representing an electron in real space. An analogue of the Foldy-Wouthuysen transformation, known from relativistic quantum mechanics, is introduced in order to decouple electron states in various bands. We demonstrate that, after the bands are decoupled, electrons should be treated as particles of a finite size. In contrast to nearly-free electrons we consider a two-band model of tightly bound electrons. We show that also in this case the electrons should experience the trembling motion. It is concluded that the phenomenon of Zitterbewegung of electrons in crystalline solids is a rule rather than an exception.

Mode mixing induced by disorder in graphene PNP junction in a magnetic field

description: We study the electron transport through the graphene PNP junction under a magnetic field and show that modes mixing plays an essential role. By using the non-equilibrium Green's function method, the space distribution of the scattering state for a specific incident modes as well the elements of the transmission and reflection coefficient matrixes are investigated. All elements of the transmission (reflection) coefficient matrixes are very different for a perfect PNP junction, but they are same at a disordered junction due to the mode mixing. The space distribution of the scattering state for the different incident modes also exhibit the similar behaviors, that they distinctly differ from each other in the perfect junction but are almost same in the disordered junction. For a unipolar junction, when the mode number in the center region is less than that in the left and right regions, the fluctuations of the total transmission and reflection coefficients are zero, although each element has a large fluctuation. These results clearly indicate the occurrence of perfect mode mixing and it plays an essential role in a graphene PNP junction transport.

description: The TW Hydrae Association is the nearest young stellar association. Among its members are HD 98800, HR 4796A, and TW Hydrae itself, the nearest known classical T Tauri star. We have observed these three stars spectroscopically between 3 and 13 microns. In TW Hya the spectrum shows a silicate emission feature that is similar to many other young stars with protostellar disks. The 11.2 micron feature indicative of significant amounts of crystalline olivine is not as strong as in some young stars and solar system comets. In HR 4796A, the thermal emission in the silicate feature is very weak, suggesting little in the way of (small silicate) grains near the star. The silicate band of HD 98800 (observed by us but also reported by Sylvester and Skinner (1996)) is intermediate in strength between TW Hya and HR 4796.

description: CEMP-s stars are long-lived low-mass stars with a very low iron content as well as overabundances of carbon and s-elements. Their peculiar chemical pattern is often explained by pollution from a AGB star companion. Recent observations have shown that most of the CEMP-s stars are in a binary system, providing support to the AGB companion scenario. A few CEMP-s stars, however, appear to be single. We inspect four apparently single CEMP-s stars and discuss the possibility that they formed from the ejecta of a previous-generation massive star, referred to as the "source" star. In order to investigate this scenario, we computed low-metallicity massive star models with and without rotation and including complete s-process nucleosynthesis. We find that non-rotating source stars cannot explain the observed abundance of any of the four CEMP-s stars. Three out of the four CEMP-s stars can be explained by a $25$ $M_{\odot}$ source star with $v_{\rm ini} \sim 500$ km s$^{-1}$ (spinstar). The fourth CEMP-s star has a high Pb abundance that cannot be explained by any of the models we computed. Since spinstars and AGB predict different ranges of [O/Fe] and [ls/hs], these ratios could be an interesting way to further test these two scenarios.

description: We study the baryon in holographic QCD with $D4/D8/\bar{D8}$ multi-$D$ brane system. In holographic QCD, the baryon appears as a topologically non-trivial chiral soliton in a four-dimensional effective theory of mesons. We call this topological soliton as Brane-induced Skyrmion. Some review of $D4/D8/\bar{D8}$ holographic QCD is presented from the viewpoints of recent hadron physics and phenomenologies. Four-dimensional effective theory with pions and $ρ$ mesons is uniquely derived from the non-abelian Dirac-Born-Infeld (DBI) action of $D8$ brane with $D4$ supergravity background, without small amplitude expansion of meson fields to discuss chiral solitons. For the hedgehog configuration of pion and $ρ$-meson fields, we derive the energy functional and the Euler-Lagrange equation of Brane-induced Skyrmion from the meson effective action induced by holographic QCD. Performing the numerical calculation, we obtain the pion profile $F(r)$ and the $ρ$-meson profile $G(r)$ of the Brane-induced Skyrmion, and estimate its total energy, energy density distribution, and root-mean-square radius. These results are compared with the experimental quantities of baryons and also with the profiles of standard Skyrmion without $ρ$ mesons. We analyze interaction terms of pions and $ρ$ mesons in Brane-induced Skyrmion, and consider the role of $ρ$-meson component appearing in baryons.

description: The Front End of the Spallation Neutron Source (SNS) extends from the Ion Source (IS), through a 65 keV LEBT, a 402.5 MHz RFQ, a 2.5 MeV MEBT, ending at the entrance to the DTL. The diagnostics suite in this space includes stripline beam position and phase monitors (BPM), toroid beam current monitors (BCM), and an emittance scanner. Provision is included for beam profile measurement, either gas fluorescence, laser-based photodissociation, or a crawling wire. Mechanical and electrical design and prototyping of BPM and BCM subsystems are proceeding. Significant effort has been devoted to packaging the diagnostic devices in minimal space. Close ties are maintained to the rest of the SNS effort, to ensure long term compatibility of interfaces and in fact share some design work and construction. The data acquisition, digital processing, and control system interface needs for the BPM, BCM, and LEBT diagnostic are similar, and we are committed to using an architecture common with the rest of the SNS collaboration.

description: Two new samples of QSOs have been constructed from recent surveys to test the hypothesis that the redshift distribution of bright QSOs is periodic in $\log(1+z)$. The first of these comprises 57 different redshifts among all known close pairs or multiple QSOs, with image separations $\leq$ 10\arcsec, and the second consists of 39 QSOs selected through their X-ray emission and their proximity to bright comparatively nearby active galaxies. The redshift distributions of the samples are found to exhibit distinct peaks with a periodic separation of $\sim 0.089 $ in $\log(1+z)$ identical to that claimed in earlier samples but now extended out to higher redshift peaks $z = 2.63, 3.45$ and 4.47, predicted by the formula but never seen before. The periodicity is also seen in a third sample, the 78 QSOs of the 3C and 3CR catalogues. It is present in these three datasets at an overall significance level $10^{-5}$ - $10^{-6}$, and appears not to be explicable by spectroscopic or similar selection effects. Possible interpretations are briefly discussed.

Linear and nonlinear convex estimator functions are developed for the linear fractional and bilinear terms. Conditions under which these functions are nonredundant are established. It is shown that additional estimators can be obtained through projections of the feasible region that can also be incorporated in a convex nonlinear underestimator problem for predicting lower bounds for the global optimum. The proposed algorithm consists of a spatial branch and bound search for which several branching rules are discussed. Illustrative examples and computational results are presented to demonstrate the efficiency of the proposed algorithm."

description: The quantitative analysis of the "catastrophic relaxation" of the coherent spin precession in $^3$He-B is presented. This phenomenon has been observed below the temperature about 0.5 T$_c$ as an abrupt shortening of the induction signal decay. It is explained in terms of the decay instability of homogeneous transverse NMR mode into spin waves of the longitudinal NMR. Recently the cross interaction amplitude between the two modes has been calculated by Sourovtsev and Fomin \cite{SF} for the so-called Brinkman-Smith configuration, i.e. for the orientation of the orbital momentum of Cooper pairs along the magnetic field, ${\bf L}\parallel {\bf H}$. In their treatment, the interaction is caused by the anisotropy of the speed of the spin waves. We found that in the more general case of the non-parallel orientation of ${\bf L}$ corresponding to the typical conditions of experiment, the spin-orbital interaction provides the additional interaction between the modes. By analyzing experimental data we are able to distinguish which contribution is dominating in different regimes.

Should the veterinarian have a mechanism to prescribe drugs in feed?

description: The import of the topic which we are discussing this morning varies greatly with type of practice activity involved, or to be more precise, the species of food animal involved with the practice activity. A food animal practitioner whose work in herd health maintenance deals primarily with the porcine species would undoubtedly manifest the strongest interest in the issue of using feed as a vehicle to provide therapeutic pharmaceuticals to animals. Since our practice activity has very little to do with swine and focuses primarily on bovines, the comments will be presented from that viewpoint. The bovine activity at Harbor Beach is primarily dairy cattle. In addition, I personally am involved in herd health maintenance practice activity with cattle feedyards throughout the state. This involvement addresses an annual turn-over rate of some 75,000 feeder cattle.

We consider both the phase of the model with unbroken gauge symmetry and the phase with spontaneously broken gauge symmetry. We show that against all odds the gauge sector of the model is always one-loop renormalizable at first order in theta^{mu nu}, perhaps, hinting at the existence of a new symmetry of the gauge sector of the model. However, we also show that the matter sector of the model is non-renormalizable whatever the phase.

The repair test of the leak showed a good result; four units were recovered out of five leak units (recover rate 80%). While an accelerating mode frequency was tuned at an operating frequency of 2857 MHz by squeezing method, a coupling mode frequency of 2847MHz and the 3.4% field flatness (peak to peak ratio) were achieved.

description: Label propagation is a heuristic method initially proposed for community detection in networks, while the method can be adopted also for other types of network clustering and partitioning. Among all the approaches and techniques described in this book, label propagation is neither the most accurate nor the most robust method. It is, however, without doubt one of the simplest and fastest clustering methods. Label propagation can be implemented with a few lines of programming code and applied to networks with hundreds of millions of nodes and edges on a standard computer, which is true only for a handful of other methods in the literature. In this chapter, we present the basic framework of label propagation, review different advances and extensions of the original method, and highlight its equivalences with other approaches. We show how label propagation can be used effectively for large-scale community detection, graph partitioning, identification of structurally equivalent nodes and other network structures. We conclude the chapter with a summary of the label propagation methods and suggestions for future research.

description: Abstract: "This paper deals with the global optimization of heat exchanger networks with fixed topology. It is shown that if linear area cost functions are assumed, as well as arithmetic mean driving force temperature differences in networks with isothermal mixing, the corresponding NLP optimization problem involves linear constraints and linear rational functions in the objective which are nonconvex. A rigorous algorithm is proposed that is based on a convex NLP underestimator that involves linear and nonlinear estimators for rational and bilinear terms which provide a tight lower bound to the global optimum. This NLP problem is used within a spatial branch and bound method for which branching rules are given. Basic properties of the proposed method are presented, and its application is illustrated with several example problems. The results show that the proposed method only requires few nodes in the branch and bound search."

description: Substantial experimental investigation has provided evidence for spin-triplet pairing in diverse classes of materials and in a variety of artificial heterostructures. A fundamental challenge in actual experiments is how to manipulate the topological behavior of $p$-wave superconductors (PSCs) that could open perspectives for applications. Such a control knob is naturally provided by the spin-triplet character of the PSC order parameter, described by the spin d-vector. Therefore, in this work we investigate the magnetic field response of one-dimensional (1d) PSCs and demonstrate that the structure of the Cooper pair spin-configuration is crucial to set topological phases with an enhanced number of Majorana fermions per edge, N, ranging from N=0 to 4. The topological phase diagram, consisting of phases with Majorana modes at the edge, becomes significantly modified when one tunes the strength of the applied field and allows for long range hopping amplitudes in the 1d PSC. We find transitions between phases with different number of Majorana fermions per edge that can be both induced by a variation of the hopping strength and a spin rotation of the d-vector. Hence, the interplay of the applied magnetic field and the internal spin degree of freedom of the PSC opens a new promising route for engineering topological phases with large number of Majorana modes.

description: Cloud computing is steadily growing and, as IaaS vendors have started to offer pay-as-you-go billing policies, it is fundamental to achieve as much elasticity as possible, avoiding over-provisioning that would imply higher costs. In this paper, we briefly analyse the orchestration characteristics of PaaSSOA, a proposed architecture already implemented for Jolie microservices, and Kubernetes, one of the various orchestration plugins for Docker; then, we outline similarities and differences of the two approaches, with respect to their own domain of application. Furthermore, we investigate some ideas to achieve a federation of the two technologies, proposing an architectural composition of Jolie microservices on Docker Container-as-a-Service layer.

description: Debris-flow hazard and risk assessments require reliable estimates of inundation area, velocity and flow depth to evaluate spatial impact and impact intensity. Semi-empirical numerical runout models that simulate bulk flow behavior with simple rheological models are useful in forecasting these parameters, however, they require calibration by back-analyzing past events. This paper presents the back-analysis of six debris flows in southwestern British Columbia using a novel automated calibration approach that systematically optimizes the Dan3D runout model to fit field observations. The calibration method yielded good simulations of runout length, but under-predicted flow depths in some cases, and over-predicted velocities in all cases. The best-fit Voellmy rheology parameters for the studied cases ranged from 46 to 531 m/s2 for the turbulence coefficient and 0.08 to 0.18 for the friction coefficient. There is a potential inverse correlation between friction coefficient and event volume. Calibrated parameters were compared to morphometric parameters for the study sites, which may be useful for guiding parameter selection once a larger dataset is calibrated. Ongoing work is focused on refining the calibration technique, including standardization of input parameters more relevant to debris flows. The long-term goal is to apply the technique to a larger dataset of debris-flow cases and provide practitioners with better guidance on the selection of model input parameters for forecasting purposes.
The Practitioner's use of a rapid progesterone assay in the dairy cow

description: Milk progesterone analysis has been available on a commercial basis for dairy producers since the early 1970’s. The methods employed at that time were based on Radioimmunoassay (RIA) techniques. Time required for results using this technique was relatively long which resulted in very little acceptance of the procedure for monitoring reproductive status in cattle. Recently, Enzymeimmunoassay (EIA) techniques have been developed for use with milk and plasma. These tests have shown good specificity and a high correlation with RIA techniques. The advantages of the EIA over current RIA techniques include ease of performing the test, relatively inexpensive equipment required, and rapid results. An EIA for progesterone in milk and plasma (a) has been available in our laboratory since late 1984 and is being used for clinical management of reproduction cases in dairy operations currently participating in our dairy reproductive herd health program.

title: Investigating the stability of amyloid assemblies towards fragmentation
Creators: name: Mishell, Mireb
Publisher: name: University of Kent

description: Amyloid fibrils are densely packed, highly polymorphic protein aggregates typically found in patients with neurodegenerative disorders such as Alzheimer's and Parkinson's disease. The fibrils are characterised by a cross-β core comprising of a succession of contiguous β-strands stacked perpendicularly to the fibril axis. The organisation attributes to the tough and highly stable nature of amyloid structures that allows them to withstand degradation and serve a variety of normal physiological functions in organisms ranging from bacteria to mammals. It is unclear why some amyloid structures are beneficial and others pathogenic. Increasing research into the amyloid lifecycle, the process by which soluble monomeric proteins and peptides misfold and self-assemble into amyloid fibrils, has revealed four main stages: primary nucleation, elongation, secondary nucleation and fibril fragmentation. Interestingly, fragmentation is thought to play a key role in the propagation of the amyloid conformation due to striking effects on the fibril structure, therefore it may provide insight into their stability and pathogenicity. In this study, the mechanical stability of in vitro formed fibrils of Sup35NM, a functional prion, and α-synuclein, a prion-like amyloid associated with Parkinson's disease, were analysed by sonication followed by atomic force microscopy imaging. Results confirm a decrease in the mean α-synuclein particle length with increased sonication, as well as an increase in the number of fibril extension sites for elongation. Both factors would significantly enhance the potential for cytotoxicity due to increased biological availability of short amyloid particles for interaction with other cellular components and membranes, the diffusion across which is further enhanced by the reduction in overall fibril size. The infective potential of amyloid particles is measured by the likelihood of internalisation of particles by cells. Therefore, fragmentation is crucial for the propagation of the amyloid conformation since it successfully increases the load of small cytotoxic amyloid species with highly infectious potentials compared to their longer counterparts.

title: Disentangling Leaders from their Parties in Public Opinion
Creators: name: Bridgewater, Jack
Publisher: name: University of Kent
Year: 2021

description: To what extent do views towards a political party inform evaluations of that party's leader? A substantial body of literature analyses the effects of both leaders and their parties in the electoral process, largely focusing on vote choice. While there are an increasing number of scholars who posit that we have underestimated the impact of leaders during elections, there is still surprisingly little research conducted on the process through which voters make up their minds about leaders. This process is important, because understanding it can further clarify the role that leaders play in people's political attitudes relative to parties. If voters' attitudes towards leaders and parties are substantially different then some of the assumptions that we make about public opinion are inaccurate. Furthermore, it has ramifications for the extent to which we should regard actions by individual leaders as having importance for public opinion. If voters do not frequently distinguish between party and leader then it is likely that the increasingly sizeable role leaders play in media coverage is unfounded. This thesis addresses public opinion towards leaders across three distinct but related papers. Firstly, given the decline of party identity in many democracies I show that there has been change over time in the way voters evaluate leaders. Secondly, drawing on recent research, I suggest that the way in which voters think about leaders is affected by whether a leader is new in the role or not. Finally, I utilise voter assessments of personality traits to provide evidence of the importance of leaders being perceived as warm rather than competent. These findings have implications for future research on the role of leaders in electoral politics and for how parties should understand the relevance of the appeal of their leaders to the public.
