description: For $N \geq 2$, an $N$-qubit doily is a doily living in the $N$-qubit symplectic polar space. These doilies are related to operator-based proofs of quantum contextuality. Following and extending the strategy of Saniga et al. (Mathematics 9 (2021) 2272) that focused exclusively on three-qubit doilies, we first bring forth several formulas giving the number of both linear and quadratic doilies for any $N > 2$. Then we present an effective algorithm for the generation of all $N$-qubit doilies. Using this algorithm for $N=4$ and $N=5$, we provide a classification of $N$-qubit doilies in terms of types of observables they feature and number of negative lines they are endowed with. We also list several distinguished findings about $N$-qubit doilies that are absent in the three-qubit case, point out a couple of specific features exhibited by linear doilies and outline some prospective extensions of our approach.

Community colleges

description: The Concurrent Courses Initiative (CCI), funded by The James Irvine Foundation from 2008 until 2011, comprised eight secondary/postsecondary partnerships across California that offered dual enrollment programs with supplemental student supports. The goal of the CCI was to expand access to supportive, career-focused dual enrollment for students often underserved by such programs and underrepresented in higher education, with the expectation that participating students would prosper in college subsequently. We use longitudinal administrative data on individual students who participated in 2008–09 and 2009–10, compared with data on other students from their districts, to test for evidence of differences in outcomes. Relative to comparison students, CCI dual enrollees had similar GPAs but higher graduation rates in high school. CCI dual enrollees entered college at similar rates to the comparison group, but entered four-year institutions and persisted at higher rates. Notably, CCI dual enrollees accumulated more college credits than the comparison group, and this difference in credit accumulation grew over time. After two years in college, CCI dual enrollees had accumulated 20 percent more credits than their district peers. These are the results of the data pooled across the sites; we also report results for the individual sites, which vary.

description: With AKARI, we obtain the spatially-resolved near-infrared (2.5 - 5.0 um) spectra for the nearby starburst galaxy M82. These spectra clearly show the absorption features due to interstellar ices. Based on the spectra, we created the column density maps of H_2O and CO_2 ices. As a result, we find that the spatial distribution of H_2O ice is significantly different from that of CO_2 ice; H_2O ice is widely distributed, while CO_2 ice is concentrated near the galactic center. Our result for the first time reveals variations in CO_2/H_2O ice abundance ratio on a galactic scale, suggesting that the ice-forming interstellar environment changes within a galaxy. We discuss the cause of the spatial variations in the ice abundance ratio, utilizing spectral information on the hydrogen recombination Brα and Brβ lines and the polycyclic aromatic hydrocarbon 3.3 um emission appearing in the AKARI near-infrared spectra.

description: We show how to prepare a steady-state entangled state between magnons and optical photons in an opto-magnomechanical configuration, where a mechanical vibration mode couples to a magnon mode in a ferrimagnet by the dispersive magnetostrictive interaction, and to an optical cavity by the radiation pressure. We find that, by appropriately driving the magnon mode and the cavity to simultaneously activate the magnomechanical Stokes and the optomechanical anti-Stokes scattering, a stationary optomagnonic entangled state can be created. We further show that, by activating the magnomechanical state-swap interaction and subsequently sending a weak red-detuned optical pulse to drive the cavity, the magnonic state can be read out in the cavity output field of the pulse via the mechanical transduction. The demonstrated entanglement and state-readout protocols in such a novel opto-magnomechanical configuration allow us to optically control, prepare, and read out quantum states of collective spin excitations in solids, and provide promising opportunities for the study of quantum magnonics, macroscopic quantum states, and magnonic quantum information processing.

description: In the Oil Industry, part of the extracted crude oil is commonly found in form of emulsions, mainly as water-in-oil (W/O) and oil-in water (O/W), emulsions, and more complex emulsions are less frequent but can also be found, such as water-in-oil-in-water (W/O/W) and oil-in-water-in-oil (O/W/O). These emulsions must be broken before the starting of the oil refining process because water generates operational problems like increasing crude viscosity, corrosion of equipment, piping and clogging of pumps and equipment, causing unscheduled production stoppages. O/W emulsions, can also be intentionally generated as a strategy to reduce the viscosity of very heavy crudes and facilitate their transport to the storage, and processing center. However, in any case, these emulsions must be broken before the crude is processed. Different technologies employing chemicals, electric fields, membranes, biological techniques, ultrasound and microwaves have been studied to favor the breaking of O/W emulsions. Microwaves have proven to be an excellent alternative to break emulsions quickly, efficiently, and with minimal energy losses. This paper review accounts for the research studies on the microwave-assisted breaking of W/O and O/W emulsions for oilfield applications with and without the simultaneous application of demulsifying chemicals. The possible mechanisms by which microwaves accelerate emulsion breakage, and their advantages for a more sustainable industry are also discussed.

description: The task of finding optimal protocols that minimize the energetic cost of thermodynamic processes of long yet finite duration $τ$ is a pressing one. We approach this problem here in a rigorous and systematic fashion by means of the adiabatic perturbation theory of closed Hamiltonian quantum systems. Our main finding is a $1/τ^2$ scaling of the excess work for large $τ$ in gapped systems. This result is at odds with the $1/τ$ prediction of the geometric approach to optimization, which is predicated on the slow evolution of open systems close to canonical equilibrium. In contrast, our approach does not lead to an obvious geometric interpretation. Furthermore, as the thermodynamic work does not depend on how an isolated quantum system is split into a system of interest and its environment, our results imply the failure of the geometric approach prediction even for open systems. Additionally, we provide alternative optimization procedures, both for slowly-varying processes described by adiabatic perturbation theory and for weakly-varying processes described by linear response theory. Our findings are benchmarked and confirmed through the application to the driven transverse-field Ising chain.

description: We present an extraction of unpolarized transverse-momentum-dependent parton distribution and fragmentation functions based on more than two thousands data points from several experiments for two different processes: semi-inclusive deep-inelastic scattering and Drell-Yan production of lepton pairs. The baseline analysis is performed with a Monte Carlo replica method resumming large logarithms at N3LL accuracy. The resulting description of the data is very good ($χ^2/N_{\rm dat} = 1.06$). For semi-inclusive deep-inelastic scattering, predictions for multiplicities are normalized by factors that cure the discrepancy with data introduced by higher-order perturbative corrections.

Professional Liability in Bovine Practice

Publisher: name: American Association of Bovine Practitioners  Proceedings of the Annual Conference
Year: 2020

description: The changing scene in veterinary malpractice is one that encompasses not only veterinarians and their modes of practice but also encompasses the livestock industry and companion animals. The profession is governed by economic values as to the service performed while the results expected are often equated to the practice of medicine. In today's era of consumerism, statements of intent to perform a service are generally taken to imply a guarantee of good results. Although professionals in the health field cannot guarantee the results of surgical, diagnostic, and medical procedures, or the use of drugs or biological agents, legal decisions in recent years increasingly have put veterinarians, like other health professionals at risk of being sued for malpractice. There will always be variables that compound a health problem, confuse the client, and create a potential claim-producing situation. A review of such incidents can help veterinarians guard against situations that predispose to malpractice claims.

title: Modular and Parameter-efficient Fine-tuning of Language Models
Creators: name: Pfeiffer, Jonas
Publisher: name: UNSPECIFIED
Year: 2023

description: Transfer learning has recently become the dominant paradigm of natural language processing. Models pre-trained on unlabeled data can be fine-tuned for downstream tasks based on only a handful of examples. A long-term goal is to develop models that acquire new information at scale without incurring negative transfer and that generalize systematically to new settings. Modular deep learning has emerged as a promising solution to these challenges, by updating parameter-efficient units of computation locally and asynchronously. These units are often implemented as modules that are interlaid between layers, interpolated with pre-trained parameters, or concatenated to the inputs. Conditioned on tasks or examples, information is routed to multiple modules through a fixed or learned function, followed by an aggregation of their outputs. This property enables compositional generalization, by disentangling knowledge and recombining it in new ways. In this thesis, we provide a unified view of modularity in natural language processing, spanning across four dimensions; specifically, we disentangle modularity into computation functions, routing functions, aggregation functions, and the training setting. Along those axes, we propose multiple contributions: a research framework which encompasses all dimensions; a novel attention-based aggregation function which combines the knowledge stored within different modules; routing mechanisms for out of distribution generalization in cross-lingual transfer scenarios; a dataset and modular training strategies for multimodal and multilingual transfer learning; a modular pre-training strategy to tackle catastrophic interference of heterogeneous data.

The dairymen's needs have changed treatment to production medicine and the question that I have is: Do we fit those needs? I guess I've had trouble thinking that we've done a poor job fitting those needs and we'd have to change. Listen to what the dairymen want and then we must provide it. Let's not provide what we want, but let's provide what those dairymen need. Let's listen to his needs and figure out what he has and what he wants to be successful.

Study of Complex Absorption and Reflection in a Unique Intermediate Polar Paloma

description: We present the broadband (0.3-40.0 keV) X-ray analysis of a unique intermediate polar Paloma using simultaneous data from XMM-Newton and NuSTAR observatories. The X-ray power spectra show strong modulations over orbital period compared to spin period. The orbit folded lightcurves show single broad hump like structure with strong dips for soft to medium X-rays (0.3-10.0 keV). The energy dependent dips at $ϕ\sim 0.16$ and $0.5$ arise due to complex intrinsic absorber, strong enough to have effect well around 15 keV. The absorber could potentially be contributed from accretion curtain/ accretion stream and absorbing material produced by stream-disc/stream-magnetosphere interactions. We notice significant variation of the absorber with orbital phase, with maximum absorption during orbital phase 0.1-0.22. The absorber requires more than one partial covering absorber component, specifying the necessity to use distribution of column densities for spectral modelling of the source. Isobaric cooling flow component is utilized to model the emission from the multi-temperature post-shock region, giving shock temperature of $31.7_{-3.5}^{+3.3}$keV, which corresponds to white dwarf mass of $0.74_{-0.05}^{+0.04}\;M_{\odot}$. We have used both the neutral absorber and the warm absorber models, which statistically give similarly good fit, but with different physical implications. Among the Fe K$_α$ line complex, the neutral line is the weakest. We probed the Compton reflection, and found minimal statistical contribution in the spectral fitting, suggesting presence of weak reflection in Paloma.

description: The unidentified infrared emission (UIE) features at 3.3, 6.2, 7.7, 8.6, and 11.3 micrometer, commonly attributed to polycyclic aromatic hydrocarbon (PAH) molecules, have been recently ascribed to mixed aromatic/aliphatic organic nanoparticles. More recently, an upper limit of <9% on the aliphatic fraction (i.e., the fraction of carbon atoms in aliphatic form) of the UIE carriers based on the observed intensities of the 3.4 and 3.3 micrometer emission features by attributing them to aliphatic and aromatic C-H stretching modes, respectively, and assuming A_34./A_3.3~0.68 derived from a small set of aliphatic and aromatic compounds, where A_3.4 and A_3.3 are respectively the band strengths of the 3.4 micrometer aliphatic and 3.3 micrometer aromatic C-H bonds. To improve the estimate of the aliphatic fraction of the UIE carriers, here we analyze 35 UIE sources which exhibit both the 3.3 and 3.4 micrometer C-H features and determine I_3.4/I_3.3, the ratio of the power emitted from the 3.4 micrometer feature to that from the 3.3 micrometer feature. We derive the median ratio to be ~ 0.12. We employ density functional theory and second-order perturbation theory to compute A_3.4/A_3.3 for a range of methyl-substituted PAHs. The resulting A_3.4/A_3.3 ratio well exceeds 1.4, with an average ratio of ~1.76. By attributing the 3.4 micrometer feature exclusively to aliphatic C-H stretch (i.e., neglecting anharmonicity and superhydrogenation), we derive the fraction of C atoms in aliphatic form to be ~2%. We therefore conclude that the UIE emitters are predominantly aromatic.

description: A wheat buffer stock simulation model is used to add random deviations of wheat yields and exports to projected supply and demand conditions for 1976-82. The result is a useful analytical tool for policy analysis—especially for the analysis of questions about price and income stability where deviations of production and use from the mean, rather than the value of the mean, are of primary interest. A simple buffer stock management rule is examined. Wheat buffer stocks would be purchased by a U.S. stocks management agency whenever the market price dropped below a specified purchase price, and stocks would be sold whenever the market price exceeded a specified sale price. The impact of alternative stock levels and alternative purchase and sale prices on the level and variation of supply, domestic and foreign sales. Government costs, and farm income are examined.

As wormholes connect two distant points through a tunnel in spacetime, this new object connects two spacetime through a large mouth which is referred to as a "Cosmic Gate". In this context, two identical copies of the regular part of the de Sitter spacetime are cut through a timelike hyperplane. Then, they are glued at their identical boundaries (the only boundary) to form a complete spacetime. The stability of the cosmic gate against a linear radial perturbation is studied as well. Finally, the radial geodesics of the spacetime for a timelike and a null particle are presented.

description: A vaccine can be defined as an attenuated microorganism, a killed microorganism, or a part or product of a microorganism which is administered to an animal for the prevention, amelioration or treatment of an infectious disease. There are a wide variety of vaccines available to the bovine practitioner for use in cattle, and therefore selecting the most appropriate vaccines for a particular situation can be difficult. The effectiveness and suitability of a vaccine depends upon the nature of the immune response it generates and on the role that the immune system may play in preventing or regulating the infectious process of a particualr microorganism.

description: Pure calcium carbonate (CaCO3) nanoparticles were synthesized by the sol-gel citrate method using either Ca (NO3)2 or CaCl2 as a precursor. CaCO3 powder analysis was conducted using X-ray diffraction (XRD), field emission-scanning electron microscope (FE-SEM), BET analysis, and Fourier-transform infrared spectroscopy (FTIR). The XRD patterns show that the pure phase of CaCO3 nanoparticles was produced at calcination temperatures of 500 °C and 600 °C with surface areas of 97.8 and 195.3 m2/g for CaCl2 and Ca (NO3) precursor, respectively. The second phase was obtained when using CaCl2 precursor compared with Ca (NO3)2. Batch experiments were conducted to study the effect of pH, initial dye concentration, adsorbent dose, and contact time on the adsorption of methyl orange (MO) dye. Three isothermal models were investigated by Freundlich, Langmuir, and Temkin, and the resulting data were well fitted into Langmuir isotherm with R2= 0.98 and adsorption capacity 110.9 mg\g. The finding reveals that 98 ± 4.9% of 50 ppm MO dye may be adsorbed at pH 2 and shaking time 2 h. Furthermore, with an increase in the initial dye concentration and dose amount, the efficiency of the removal process increases. The adsorption kinetic behavior is well acceptable with pseudo-second-order. Desorption experiments were conducted to regenerate the adsorbent with an efficiency of 92.9 ± 4.6%.

description: We present the results from a wide-field imaging study of globular cluster (GC) systems in three early-type galaxies. Combinations of Subaru/Suprime-Cam, CFHT/MegaCam and HST/WFPC2/ACS data were used to determine the GC system properties of three highly flattened galaxies NGC 720, NGC 1023 and NGC 2768. This work is the first investigation of the GC system in NGC 720 and NGC 2768 to very large galactocentric radius ($\sim$ 100 kpc). The three galaxies have clear blue and red GC subpopulations. The radial surface densities of the GC systems are fitted with Sersic profiles, and detected out to 15, 8 and 10 galaxy effective radii respectively. The total number of GCs and specific frequency are determined for each GC system. The ellipticity of the red subpopulation is in better agreement with the host galaxy properties than is the blue subpopulation, supporting the traditional view that metal-rich GCs are closely associated with the bulk of their host galaxies' field stars, while metal-poor GCs reflect a distinct stellar halo. With the addition of another 37 literature studied galaxies, we present a new correlation of GC system extent with host galaxy effective radius. We find a dependence of the relative fraction of blue to red GCs with host galaxy environmental density for lenticular galaxies (but not for elliptical or spiral galaxies). We propose that tidal interactions between galaxies in cluster environments might be the reason behind the observed trend for lenticular galaxies.

Community colleges

description: With their open access admission policies, low tuition costs, and convenient locations, community colleges are designed to make college accessible to all. They strive to meet three main goals. The first is to teach marketable vocational skills, the second is to provide the first two years of a four-year bachelor’s degree program, and the third is to provide continuing education and enrichment for community residents. This paper covers issues that are relevant to the community college mission of helping prepare a skilled workforce for jobs offering reasonable wages. After providing an overview about community colleges and their students, the paper discusses the types of remedial education programs that are most likely to provide the large number of underprepared students enrolled in community colleges with the skills to advance to college-level courses. It considers the growing phenomenon of dual enrollment that enables students to earn both high school and college credit for courses while still in high school. It addresses the ways that community colleges can support local labor markets and regional economic development and their efforts to build career pathways for workers. It describes the growing role of community colleges in online education, and it reviews the financing of community colleges. The paper also discusses issues related to community college persistence and completion, and it cites evidence of the market value of the education and credentials the colleges provide. Finally, it considers the usefulness of the American community college as a model for other countries seeking to develop institutions that serve similar functions.

description: In the current study, folic acid-modified silica nanoparticles (FA-SNPs) were fabricated and used for the removal of Al(III) from aqueous media via solid-phase extraction (SPE) procedure before its spectrometric determination using flame atomic absorption spectrometry (FAAS). The prepared adsorbent was characterized by elemental analysis, infrared spectroscopy (FTIR), scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray powder diffraction (XRD), Brunauer-Emmett-Teller (BET) surface area measurement, and pH at a point of zero charge (pHpzc). Thermogravimetric analysis (TGA) was used to prove the thermal stability of the prepared adsorbent. The influence of several parameters including initial pH, amount of adsorbent, time of contact, initial adsorbate concentration, and the effect of foreign ions was studied. The outcomes presented that optimum adsorption of Al(III) was achieved at pH 3.5, contact time of 30 min, adsorbent dosage of 25 mg, and 25 °C. The experimental data agreed well with the pseudo-2nd order model and was fitted by the Langmuir model with adsorption capacity equal to 17.52 ± 0.122 mg/g. Thermodynamic analysis revealed that the adsorption of Al(III) was spontaneous and exothermic. The procedure was successfully applied for the recovery of Al(III) spiked to some real water samples. The regeneration study using HNO3 indicated the excellent regenerative power of the prepared adsorbent. Moreover, pH-metric titration was used to prove the complexation between Al(III) and the surface of the prepared adsorbent. The obtained results showed that FA-SNPs is an effective, eco-friendly, and low-cost adsorbent that can be used for the removal of Al(III) from aqueous solution.

description: Scrotal circumference measurements were collected on 2,714 young bulls at the time they entered one of three bull test stations operated by the Virginia Beef Cattle Improvement Association during the years 1982-1988. Scrotal circumference measurements were collected again at the time bulls completed the 140 day test-of-gain period. Because of a 14 day adaptation period the time between measurements was 154 days. Data were also collected for breed, days of age at start of test, weight at start and end of test, and frame score at end of test. Bulls ranged from 156 days to 371 days of age at start of test with an average of 257 days. The average beginning weight was 339 kg (range 182 to 575 kg) and the average ending weight was 530 kg (range 331 to 786 kg).

description: In this work, the hierarchical porous SnO2-ZnO microspheres have been successfully synthesized by hydrothermal method followed by calcination. The structure, chemical composition, specific surface area and morphology of as-synthesized samples were detailed characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), photoluminescence spectroscopy (PL), Brunauer-Emmett-Teller (BET), scanning electron microscopy (SEM) and transmission electron microscopy (TEM), respectively. The results indicate that the response of hierarchical porous SnO2-ZnO microspheres-based sensor toward 100 ppm ethanol is 74 at low working temperature (225 °C), which is higher than that of pure hierarchical porous ZnO microspheres-based sensor (39). Moreover, the hierarchical porous SnO2-ZnO microspheres-based sensor presents fast response and recovery time (4 s, 6 s), good selectivity, repeatability and stability. Therefore, the sensor based on hierarchical porous SnO2-ZnO microspheres will be a potential candidate for ethanol detection.

description: Details about the velocity distribution of weakly interacting massive particle (WIMP) dark matter in our galaxy may be revealed by nuclear-recoil detectors with directional sensitivity. Previous studies have assumed that the velocity distribution takes a simple functional form characterized by a small number of parameters. More recent work has shown that basis-function expansions may allow for more general parameterization; such an approach has been considered for both the one-dimensional speed and momentum distributions, and also for three-dimensional velocity distributions obeying certain equilibrium conditions. In this work, I extend this basis-function approach to allow for arbitrary velocity distributions by working in the Fourier-Bessel basis, deriving an analytic expression for the directional recoil spectrum. Such an approach is completely general, and may be useful if the velocity distribution is too complex to be characterized by simple functional forms or is not completely virialized. Results concerning the three-dimensional Radon transform of the Fourier-Bessel basis functions may be of general interest for tomographic applications.

description: Johne's disease (paratuberculosis) (JD) is a chronic progressive bacterial enteropathy. Infected animals have generally been exposed to the organism at a very young age. Clinical signs of weight loss and diarrhea are often preceded by a period of months or years during which M. paratuberculosis organisms are shed in feces. The effect of subclinical JD on production and economic parameters has not been well characterized. A study of randomly selected cull dairy cows was conducted at a large plant slaughtering cull cows from throughout the northeastern U.S. Johne's positive cull cows weighed less, produced less milk during their lifetime and less milk during their last lactation than did Johne's negative cull cows.

description: Cosmology is entering an era of percent level precision due to current large observational surveys. This precision in observation is now demanding more accuracy from numerical methods and cosmological simulations. In this paper, we study the accuracy of $N$-body numerical simulations and their dependence on changes in the initial conditions and in the simulation algorithms. For this purpose, we use a series of cosmological $N$-body simulations with varying initial conditions. We test the influence of the initial conditions, namely the pre-initial configuration (preIC), the order of the Lagrangian perturbation theory (LPT), and the initial redshift, on the statistics associated with the large scale structures of the universe such as the halo mass function, the density power spectrum, and the maximal extent of the large scale structures. We find that glass or grid pre-initial conditions give similar results at $z\lesssim 2$. However, the initial excess of power in the glass initial conditions yields a subtle difference in the power spectra and the mass function at high redshifts. The LPT order used to generate the ICs of the simulations is found to play a crucial role. First-order LPT (1LPT) simulations underestimate the number of massive haloes with respect to second-order (2LPT) ones, typically by 2% at $10^{14} h^{-1} M_\odot$ for an initial redshift of 23, and the small-scale power with an underestimation of 6% near the Nyquist frequency for $z_\mathrm{ini} = 23$. Moreover, at higher redshifts, the high-mass end of the mass function is significantly underestimated in 1LPT simulations. On the other hand, when the LPT order is fixed, the starting redshift has a systematic impact on the low-mass end of the halo mass function.

Competing magnetism in $π$ electrons in graphene with a single carbon vacancy

description: One intriguing finding in graphene is the vacancy-induced magnetism that highlights the interesting interaction between local magnetic moments and conduction electrons. Within density functional theory, the current understanding of the ground state is that a Stoner instability gives rise to ferromagnetism of $π$ electrons aligned with the localized moment of a $σ$ dangling bond and the induced $π$ magnetic moments vanish at low vacancy concentrations. However, the observed Kondo effect suggests that $π$ electrons around the vacancy should antiferromagnetically couple to the local moment and carry non-vanishing moments. Here we propose that a phase possessing both significant out-of-plane displacements and $π$ bands with antiferromagnetic coupling to the localized $σ$ moment is the ground state. With the features we provide, it is possible for spin-resolved STM, STS, and ARPES measurements to verify the newly proposed phase.

description: This paper investigates the determinants of end-user adoption of the DuckDuckGo search engine coupling the standard UTAUT model with factors to reflect reputation, risk, and trust. An experimental approach was taken to validate our model, where participants were exposed to the DuckDuckGo product using a vignette. Subsequently, answering questions on their perception of the technology. The data was analyzed using the partial least squares-structural equation modeling (PLS-SEM) approach. From the nine distinct factors studied, we found that 'Performance Expectancy' played the greatest role in user decisions on adoption, followed by 'Firm Reputation', 'Initial Trust in Technology', 'Social Influence', and an individual's 'Disposition to Trust'. We conclude by exploring how these findings can explain DuckDuckGo's rising prominence as a search engine.
