description: No abstracts are to be cited without prior reference to the author.The accuracy of acoustic surveys for the estimation of fish resources can be compromised by uncertainties associated with the identification of echotraces to species. This study aims to determine the multifrequency scattering characteristics of echotraces of the pelagic species, herring (Clupea harengus) and Norway pout (Trisopterus esmarkii) which co-habit similar areas of the North Sea in summer. These species are acoustically quite similar: both possess swimbladders; both occur in densely packed schools close to the seabed; and the schools are similar in shape and size. As a result, their echotraces have traditionally been difficult to distinguish. Norway pout, are however, usually much smaller than herring in size, such that their frequency specific acoustic signature may differ. The scattering properties at different frequencies are, therefore, possible important discriminating characteristics which could lead to an algorithm for the identification of each species. Data were taken from the International North Sea Herring Acoustic Surveys, in the summers of 2000, 2001 and 2002. The data comprised of mean volume backscattering strengths (MVBS) at 18, 38, 120 and 200 kHz from a scientific echosounder, ground truthed with samples taken from a pelagic trawl. Positional, morphological and energetic features of the echotraces were examined using a clustering technique indicating that the statistical characteristics of the energetic variables provided the best discriminating capacity. However, no significant signature was found to distinguish between the species. Indications are that a more thorough analysis of echotrace parameters in conjunction with environmental covariates may prove more useful in discriminating between these two species.

description: Using MUSE on the ESO-VLT, we obtained a 4 hour exposure of the z=3.12 radio galaxy MRC0316-257. We detect features down to ~10^-19 erg/s/cm^2/arcsec^2 with the highest surface brightness regions reaching more than a factor of 100 higher. We find Ly-alpha emission out to ~250 kpc in projection from the active galactic nucleus (AGN). The emission shows arc-like morphologies arising at 150-250 kpc from the nucleus in projection with the connected filamentary structures reaching down into the circum-nuclear region. The most distant arc is offset by 700 km/s relative to circum-nuclear HeII 1640 emission, which we assume to be at the systemic velocity. As we probe emission closer to the nucleus, the filamentary emission narrows in projection on the sky, the relative velocity decreases to ~250 km/s, and line full-width at half maximum range from 300-700 km/s. From UV line ratios, the emission on scales of 10s of kpc from the nucleus along a wide angle in the direction of the radio jets is clearly excited by the radio jets and ionizing radiation of the AGN. Assuming ionization equilibrium, the more extended emission outside of the axis of the jet direction would require 100% or more illumination to explain the observed surface brightness. High speed (>300 km/s) shocks into rare gas would provide sufficiently high surface brightness. We discuss the possibility that the arcs of Ly-alpha emission represent accretion shocks and the filamentary emission represent gas flows into the halo, and compare our results with gas accretion simulations.

description: A challenge in isogeometric analysis is constructing analysis-suitable volumetric meshes which can accurately represent the geometry of a given physical domain. In this paper, we propose a method to derive a spline-based representation of a domain of interest from voxel-based data. We show an efficient way to obtain a boundary representation of the domain by a level-set function. Then, we use the geometric information from the boundary (the normal vectors and curvature) to construct a matching C1 representation with hierarchical cubic splines. The approximation is done by a single template and linear transformations (scaling, translations and rotations) without the need for solving an optimization problem. We illustrate our method with several examples in two and three dimensions, and show good performance on some standard benchmark test problems.

description: We present the first complete confirmation of Granovetter's theory of social networks using a massive dataset. For this purpose, we study a scientific collaboration network, which is considered one of the most important examples that contradicts the universality of this theory. We achieve this goal by rejecting the assumption of the symmetry of social ties. Our approach is grounded in well-established heterogeneous (degree-based) mean-field theory commonly used to study dynamical processes on complex networks. Granovetter's theory is based on two hypotheses that assign different roles to interpersonal, information-carrying connections. The first hypothesis states that strong ties carrying the majority of interaction events are located mainly within densely connected groups of people. The second hypothesis maintains that these groups are connected by sparse weak ties that are of vital importance for the diffusion of information - individuals who have access to weak ties have an advantage over those who do not. Given the scientific collaboration network, with strength of directed ties measured by the asymmetric fraction of joint publications, we show that scientific success is strongly correlated with the structure of a scientist's collaboration network. First, among two scientists, with analogous achievements, the one with weaker ties tends to have the higher h-index, and second, teams connected by such ties create more valuable publications.

description: No abstracts are to be cited without prior reference to the author.The relative frequency response is an important acoustic feature used to characterise acoustic targets. This response has been defined as the sv, volume backscattering coefficient, for a specific frequency relative to that of a reference frequency (38 kHz). The acoustic data commonly used in these calculations are derived from integrated measurements in a region containing multiple targets. In this study the relative frequency responses at 18, 38, 70, 120, and 200 kHz have additionally been measured using filtered target strength data on all frequencies. The spatial comparability of the sv-data is thus avoided, while the single-target detection becomes a new challenge. Target strength was extracted from in situ measurements, using calibrated and digitised data from a Simrad EK60 with split-beam transducers transmitting simultaneously at all five frequencies. Selected series with nearly pure catches of Atlantic cod (Gadus Morhua L.), saithe (Pollachius virens L.) and Norway pout (Trisopterus esmarkii L.) were analysed. The frequency response derived by the new method is compared with standard integration method.

description: Realistic modeling of qubit systems including noise and constraints imposed by control hardware is required for performance prediction and control optimization of quantum processors. We introduce qopt, a software framework for simulating qubit dynamics and robust quantum optimal control considering common experimental situations. To this end, we model open and closed qubit systems with a focus on the simulation of realistic noise characteristics and experimental constraints. Specifically, the influence of noise can be calculated using Monte Carlo methods, effective master equations or with the efficient filter function formalism, which enables the investigation and mitigation of auto-correlated noise. In addition, limitations of control electronics including finite bandwidth effects as well as nonlinear transfer functions and drive-dependent noise can be considered. The calculation of gradients based on analytic results is implemented to facilitate the efficient optimization of control pulses. The software easily interfaces with QuTip, is published under an open source license, well-tested and features a detailed documentation.

description: No abstracts are to be cited without prior reference to the author.Application of acoustic data to groundfish stock estimation is usually received with a degree of reserve. This is mainly due to the existence of the so called acoustic dead zone above the bottom, which could hide that part of the biomass closest to the seabed. In general echo integration is carried out with a back step from the seabed to avoid including seabed in the water column integral. Bottom trawl catches can some times be related to the echo-traces close to the seabed, however, on other occasions a significant catch might not be confirmed by fish observations in the echogram. In this case, it is possible that the fish were close enough to the sea bed to be eliminated by the back step. The approach adopted in this paper was to re-examine the back step to determine if there was any further information available to relate to trawl catches, in other words, can we find anything useful in this normally discarded data. To test this, the bottom line was corrected on a ping-by-ping basis to remove any seabed contamination, and then the data were integrated for those tows where there was a good catch but no corresponding echo-trace to go with it. The echograms underwent some level of scrutiny to make sure catches of mid-water species and their corresponding echotraces were not included in the analysis. Initial results presented weak correlations, suggesting that any information present in the back step is of little use in relating acoustic and trawl data.

description: The forecasting of control reserve prices is essential in order to participate reasonably in the auctions. Having identified a lack of related literature, we therefore deploy approaches based on auto-regressive and exogenous factors coming from econometrics and artificial intelligence and set up a forecasting framework. We use SARIMA and SARIMAX models as well as neural networks and forecast based on a rolling one-step forecast with re-estimation of the models. It turns out, that the combination of auto-regressive and exogenous factors yields the best results compared to approaches solely considering auto-regressive or exogenous factors. Further, the artificial intelligence approach outperforms the econometric approach in terms of forecast quality, whereas for the further use of the generated models, the econometric approach has advantages in terms of interpretability.

description: This talk was presented by Acharya Sthaneshwar Timalsina at the San Diego Vedanta Society (@sandiegovedantamonastery5096) on January 28, 2023.
The talk begins at 2:19

Dr. Timalsina opens the lecture by clearing up common misconceptions surrounding Tantra. He then discusses what Vedānta really means and what Tantra really means. Acharya moves on to elucidate a core Vedānta text, the Brahma Sutra with Shankaracharya's commentary, discussing its three core sections. Dr. Timalsina raises the vidyās of the Upanishads, demonstrating parallels between Tantric practices and vidyas such as dahara, udgita, bhuma, agni, prana, madhu. Acharya stresses the importance of these upāsanās, encouraging us to understand the depth of rishis' practice that progressively leads to self-realization and teachings, rather than seeking to flatten experiences into philosophical abstractions.
Acharya also paints the teachings of cosmology from Tantras, which place value on the human body as an instrument for self-realization. In this vein, he presents the teaching of the koshas in a new, affirming light. Rather than try to negate our physical presence, Dr. Timalsina urges us to consider the value of the totality of our experience.

Acharya's presentation allows us to better understand both Vedānta and Tantra, giving us valuable insight of practical value into how these traditions flow together.

description: The Sachdev-Ye-Kitaev (SYK) model is a model of $q$ interacting fermions. Gross and Rosenhaus have proposed a generalization of the SYK model which involves fermions with different flavors. In terms of Feynman graphs, those flavors are reminiscent of the colors used in random tensor theory. This gives us the opportunity to apply some modern, yet elementary, tools developed in the context of random tensors to one particular instance of such colored SYK models. We illustrate our method by identifying all diagrams which contribute to the leading and next-to-leading orders of the 2-point and 4-point functions in the large $N$ expansion, and argue that our method can be further applied if necessary. In a second part we focus on the recently introduced Gurau-Witten tensor model and also extract the leading and next-to-leading orders of the 2-point and 4-point functions. This analysis turns out to be remarkably more involved than in the colored SYK model.

description: Adequate colostral transfer of immunoglobulins is critical to the health of the dairy calf. However, colostrum and waste milk can also serve as an efficient mode of transmission for pathogens including Mycoplasma spp and Mycobacterium avium subsp paratuberculosis, the causative agent for Johne's disease. Pasteurization and colostrum substitutes are successful means of eliminating this threat, but are cost-restrictive for many smaller dairy producers. There is a critical need for an alternative method to prevent the transmission of these diseases while maintaining adequate passive transfer of immunoglobulins. This study examines the use of acidification of colostrum and waste milk using formic acid as a control system for these pathogens while maintaining the integrity of the immunoglobulins.

description: Cometary dust provides a unique window on dust growth mechanisms during the onset of planet formation. Measurements by the Rosetta spacecraft show that the dust in the coma of comet 67P/Churyumov-Gerasimenko has a granular structure at size scales from sub-um up to several hundreds of um, indicating hierarchical growth took place across these size scales. However, these dust particles may have been modified during their collection by the spacecraft instruments. Here we present the results of laboratory experiments that simulate the impact of dust on the collection surfaces of COSIMA and MIDAS, instruments onboard the Rosetta spacecraft. We map the size and structure of the footprints left by the dust particles as a function of their initial size (up to several hundred um) and velocity (up to 6 m/s). We find that in most collisions, only part of the dust particle is left on the target; velocity is the main driver of the appearance of these deposits. A boundary between sticking/bouncing and fragmentation as an outcome of the particle-target collision is found at v ~ 2 m/s. For velocities below this value, particles either stick and leave a single deposit on the target plate, or bounce, leaving a shallow footprint of monomers. At velocities > 2 m/s and sizes > 80 um, particles fragment upon collision, transferring up to 50 per cent of their mass in a rubble-pile-like deposit on the target plate. The amount of mass transferred increases with the impact velocity. The morphologies of the deposits are qualitatively similar to those found by the COSIMA instrument.

description: No abstracts are to be cited without prior reference to the author.The accuracy of the multi-frequency species identification and separation algorithms may be significantly improved when the detailed acoustic scattering characteristics of the fish are known, including its expected variability and uncertainty. The modeling approach is effective for interpreting measured data collected for different fish species and may give a better understanding of the acoustic scattering characteristics. The paper is motivated by development of algorithms of multi-frequency species identification and separation of three economically valuable North European fish species: Atlantic mackerel, Norwegian spring spawn herring and Norway pout. The backscattering by these fish is studied using an advanced modeling approach, and the results of the analysis are compared with selected multi-frequency recordings. This allows for an explanation of the main backscattering mechanisms over the selected frequency range and often a better understanding of the dominating acoustic scattering parameters. The impact of fish orientation behavior, pressure (for herring) and the morphological state of the fish is also discussed. Typical backscattering frequency responses for herring, mackerel and Norway pout are explained theoretically. The obtained results may be a base for improving the automatic identification algorithms now introduced in scientific echo sounder post-processing systems
Effect of OmniGen-AF on Immune Markers and Neutrophil Function in Lactating Dairy Cows

description: The immune system of the lactating dairy cow is significantly compromised at the time of calving and for several weeks thereafter. Animals in early lactation are frequently exposed to additional stress factors that result in immunosuppression, such as metabolic disease, metritis, environmental conditions, cow comfort, overcrowding, etc. Good transition cow management involves minimizing stress factors in order to improve immunity. In previous studies, the feeding of a proprietary ingredient blend, OmniGen AF (Prince-Agri Products) has been observed to increase the expression of markers of innate immunity and neutrophil function. This study was conducted in order to determine if OmniGen AF could augment the production of the immune markers L-Selectin (CD62L) and Interleukin 8 Receptor (IL8R), as well as improve neutrophil function by enhancing the in vitro phagocytosis of Streptococcus uberis.

description: We investigate the algebraic reasoning of quantum programs inspired by the success of classical program analysis based on Kleene algebra. One prominent example of such is the famous Kleene Algebra with Tests (KAT), which has furnished both theoretical insights and practical tools. The succinctness of algebraic reasoning would be especially desirable for scalable analysis of quantum programs, given the involvement of exponential-size matrices in most of the existing methods. A few key features of KAT including the idempotent law and the nice properties of classical tests, however, fail to hold in the context of quantum programs due to their unique quantum features, especially in branching. We propose Non-idempotent Kleene Algebra (NKA) as a natural alternative and identify complete and sound semantic models for NKA as well as their quantum interpretations. In light of applications of KAT, we demonstrate algebraic proofs in NKA of quantum compiler optimization and the normal form of quantum while-programs. Moreover, we extend NKA with Tests (i.e., NKAT), where tests model quantum predicates following effect algebra, and illustrate how to encode propositional quantum Hoare logic as NKAT theorems.

description: No abstracts are to be cited without prior reference to the author.Recent developments and success in acoustic seabed classification has prompted us to use ideas from this field to explore the important and limiting question of species discrimination in fisheries acoustic data. Many parallels exist between backscattered signals from the seabed and from fish/plankton especially when we view echograms as echo intensity maps analogous to multibeam seabed images. Our approach is similar to that used for multibeam seabed classification. We divide the echogram into cells, each containing echo intensity information from a small depth interval and a small number of pings. Image processing techniques then capture features that characterize the acoustic structure of each cell. PCA is then used to find the most effective feature combinations. This is followed by K-means partition for unsupervised classification. Classes reflect the acoustic diversity of the cells, a prerequisite for species classification. The process is useful to find features that will yield a high level of acoustic diversity and to explore the amount of species information that is available. We tested a subset of this approach on data that were collected with a 38 kHz Simrad EK500 echo sounder during a Pacific hake (Merluccius productus) assessment survey in the Strait of Georgia, British Columbia, Canada. The analysis focused on acoustic returns from hake, rockfish, and plankton aggregations that were 'ground-truthed' with catch information. More than 50 cells with different species, densities and depths were selected. Features were obtained from two multi-fractal analysis methods, which were applied to backscatter (SV) data without, and with thresholds of -80 and -70 dB. Each method generated a set of 33 features. Sets were submitted individually and in combination to PCA. The first three principal components contained 90% or more of the variance. Feature classification with K-means partitioning generated classes that showed significant acoustic diversity and good correspondence between acoustic classes and species. These results are encouraging and tests on a larger data set of single and multi-frequency data and with a wider range of different features are planned. For multi-frequency data, dB differencing could provide additional features.

description: Inspired by the human brain, there is a strong effort to find alternative models of information processing capable of imitating the high energy efficiency of neuromorphic information processing. One possible realization of cognitive computing are reservoir computing networks. These networks are built out of non-linear resistive elements which are recursively connected. We propose that a skyrmion network embedded in frustrated magnetic films may provide a suitable physical implementation for reservoir computing applications. The significant key ingredient of such a network is a two-terminal device with non-linear voltage characteristics originating from single-layer magnetoresistive effects, like the anisotropic magnetoresistance or the recently discovered non-collinear magnetoresistance. The most basic element for a reservoir computing network built from "skyrmion fabrics" is a single skyrmion embedded in a ferromagnetic ribbon. In order to pave the way towards reservoir computing systems based on skyrmion fabrics, here we simulate and analyze i) the current flow through a single magnetic skyrmion due to the anisotropic magneto-resistive effect and ii) the combined physics of local pinning and the anisotropic magneto-resistive effect.

description: The diagnosis of clinical salmonellosis in dairy cattle is usually based on clinical examination of the animal and bacteriological culture of the feces. Bacteriological culture is considered the gold standard for the diagnosis of salmonellosis, but the few studies that have evaluated its performance have indicated that it might suffer from a less than ideal sensitivity.

description: Simulations of tidal streams show that close encounters with dark matter subhalos induce density gaps and distortions in on-sky path along the streams. Accordingly, observing disrupted streams in the Galactic halo would substantiate the hypothesis that dark matter substructure exists there, while in contrast, observing collimated streams with smoothly varying density profiles would place strong upper limits on the number density and mass spectrum of subhalos. Here, we examine several measures of stream "disruption" and their power to distinguish between halo potentials with and without substructure and with different global shapes. We create and evolve a population of 1280 streams on a range of orbits in the Via Lactea II simulation of a Milky Way-like halo, replete with a full mass range of ΛCDM subhalos, and compare it to two control stream populations evolved in smooth spherical and smooth triaxial potentials, respectively. We find that the number of gaps observed in a stellar stream is a poor indicator of the halo potential, but that (i) the thinness of the stream on-sky, (ii) the symmetry of the leading and trailing tails, and (iii) the deviation of the tails from a low-order polynomial path on-sky ("path regularity") distinguish between the three potentials more effectively. We find that globular cluster streams on low-eccentricity orbits far from the galactic center (apocentric radius ~ 30-80 kpc) are most powerful in distinguishing between the three potentials. If they exist, such streams will shortly be discoverable and mapped in high dimensions with near-future photometric and spectroscopic surveys.

description: This paper presents a novel backtracking strategy for additive Schwarz methods for general convex optimization problems as an acceleration scheme. The proposed backtracking strategy is independent of local solvers, so that it can be applied to any algorithms that can be represented in an abstract framework of additive Schwarz methods. Allowing for adaptive increasing and decreasing of the step size along the iterations, the convergence rate of an algorithm is greatly improved. Improved convergence rate of the algorithm is proven rigorously. In addition, combining the proposed backtracking strategy with a momentum acceleration technique, we propose a further accelerated additive Schwarz method. Numerical results for various convex optimization problems that support our theory are presented.

description: Skin impedance is a measurement of electrical conductivity on the surface of the skin. Impedence is affected by ion content at the surface of the dermal epithelium. Increased sympathetic tone changes skin impedence. Sympathetic tone is proportionately associated with pain or distress, therefore skin impedence may be measured in an attempt to quantify "clinical pain/ distress". This relatively new technology may be able to demonstrate differences with the intensity of patient "distress". Skin impedence is measured by use of a tool which measures electrodermal activity (EDA).

description: No abstracts are to be cited without prior reference to the author.Calibrated, digitised data from simultaneously working multi-frequency echo sounders with nearly identical and overlapping acoustic beams have been used to generate new, synthetic echograms where only targets identified as Atlantic mackerel are retained. Echo sounder raw data are processed stepwise in a modular sequence of analysis to improve the ability to categorise acoustic targets. The relative frequency response measured over up to six acoustic frequencies, 18, 38, 70, 120, 200 and 364 kHz, is the main acoustic feature used to characterise acoustic backscatter. Mackerel seems to have a frequency-independent backscatter below approximately 100 kHz, and above approximately 200kHz, but at 4 times higher level of the backscatter. Results from numeric modelling explaining the measured relative frequency response of mackerel are shown. Synthetic echograms containing targets identified acoustically as mackerel are presented and evaluated against trawl catches. Even though catching of the fast-swimming mackerel is difficult, the trawl catches from two Norwegian research vessels confirm that the targets identified acoustically as mackerel is really mackerel.

description: Nanoscale infrared (IR) resonators with sub-diffraction limited mode volumes and open geometries have emerged as new platforms for implementing cavity quantum electrodynamics (QED) at room temperature. The use of infrared (IR) nano-antennas and tip nanoprobes to study strong light-matter coupling of molecular vibrations with the vacuum field can be exploited for IR quantum control with nanometer and femtosecond resolution. In order to accelerate the development of molecule-based quantum nano-photonic devices in the mid-IR, we develop a generally applicable semi-empirical quantum optics approach to describe light-matter interaction in systems driven by mid-IR femtosecond laser pulses. The theory is shown to reproduce recent experiments on the acceleration of the vibrational relaxation rate in infrared nanostructures, and also provide physical insights for the implementation of coherent phase rotations of the near-field using broadband nanotips. We then apply the quantum framework to develop general tip-design rules for the experimental manipulation of vibrational strong coupling and Fano interference effects in open infrared resonators. We finally propose the possibility of transferring the natural anharmonicity of molecular vibrational levels to the resonator near-field in the weak coupling regime, to implement intensity-dependent phase shifts of the coupled system response with strong pulses. Our semi-empirical quantum theory is equivalent to first-principles techniques based on Maxwell's equations, but its lower computational cost suggests its use a rapid design tool for the development of strongly-coupled infrared nanophotonic hardware for applications ranging from quantum control of materials to quantum information processing.

description: Standards of surgical practice are not well defined in veterinary medicine as a profession. These issues are largely addressed in the course of litigation and often hinge upon the personal opinion of board certified experts working in controlled settings. We expect that the standards of surgical practice in an idealized setting bear little resemblance to that utilized in field settings in bovine practice. The purpose of this study was to gain insight into current "standards of surgery" among veterinarians in private practice.
