description: Short-form videos are popular on platforms like TikTok and Instagram as they quickly capture viewers' attention. Many creators repurpose their long-form videos to produce short-form videos, but creators report that planning, extracting, and arranging clips from long-form videos is challenging. Currently, creators make extractive short-form videos composed of existing long-form video clips or abstractive short-form videos by adding newly recorded narration to visuals. While extractive videos maintain the original connection between audio and visuals, abstractive videos offer flexibility in selecting content to be included in a shorter time. We present Lotus, a system that combines both approaches to balance preserving the original content with flexibility over the content. Lotus first creates an abstractive short-form video by generating both a short-form script and its corresponding speech, then matching long-form video clips to the generated narration. Creators can then add extractive clips with an automated method or Lotus's editing interface. Lotus's interface can be used to further refine the short-form video. We compare short-form videos generated by Lotus with those using an extractive baseline method. In our user study, we compare creating short-form videos using Lotus to participants' existing practice.

description: This paper examines the preferred share arrangement for both landlords and tenants producing grain in the Texas High Plains (based on risk preference), and determines the sensitivity to changing input costs and market prices. Results of the analyses show that tenants and landlords prefer different arrangements in all scenarios. Results also indicate that a tenant would prefer a different lease arrangement in 2008 than in 2005, while the landlord’s preference would remain unchanged.

description: Scientific understanding regarding causes of climate change is maturing. Earlier indications that atmospheric CO2 is the primary cause have been challenged by recent studies. Evidence against anthropogenic global warming is mounting. Subsidized alternative fuel initiatives may run out of support once political opinion aligns with scientific realities. First steps toward policy statements within professional organizations that reflect our current understanding of forces driving climate change are called for. We as farm or timberland managers, investors, lenders, appraisers or consultants in these fields should update our understanding. Agriculture’s potential contribution toward cost effective alternative fuel sources and energy independence is discussed.

description: We use the structure of finite-dimensional graded algebras to develop the theory of antilinear representations of finite $C_2$-graded groups. A finite $C_2$-graded group is a finite group with a subgroup of index 2. In this theory the subgroup acts linearly, while the other coset acts antilinearly. We introduce antilinear blocks, whose structure is a crucial component of the theory. Among other things, we study characters and Frobenius-Schur indicators. As an example, we describe the antilinear representations of the $C_2$-graded group $A_n \leq S_n$.

description: The Quantum Fourier Transformation ($QFT$) is a key building block for a whole wealth of quantum algorithms. Despite its proven efficiency, only a few proof-of-principle demonstrations have been reported. Here we utilize $QFT$ to enhance the performance of a quantum sensor. We implement the $QFT$ algorithm in a hybrid quantum register consisting of a nitrogen-vacancy (NV) center electron spin and three nuclear spins. The $QFT$ runs on the nuclear spins and serves to process the sensor - NV electron spin signal. We demonstrate $QFT$ for quantum (spins) and classical signals (radio frequency (RF) ) with near Heisenberg limited precision scaling. We further show the application of $QFT$ for demultiplexing the nuclear magnetic resonance (NMR) signal of two distinct target nuclear spins. Our results mark the application of a complex quantum algorithm in sensing which is of particular interest for high dynamic range quantum sensing and nanoscale NMR spectroscopy experiments.

The effects of prolonged strenuous exercise on beta-receptor responsiveness in male and female triathletes
Creators: name: Scott, Jessica
Publisher: name: University of British Columbia
Year: 2009

description: The purpose of this investigation was to determine whether alterations in p-receptor responsiveness occur as a result of a single bout of prolonged strenuous exercise (PSE), and whether the myocardium of males and females responds differently to PSE. We examined nine male and eight female triathletes during three separate sessions: before, immediately after, and 24h following a half-ironman triathlon. Athletes were assessed during each session using dobutamine stress echocardiography. Steady-state graded infusions of dobutamine were used to assess p-adrenoreceptor responsiveness. Slopes calculated from linear regressions between dobutamine doses and changes in heart rate and contractility for each subject were used as an index of (3-adrenoreceptor responsiveness. Fractional shortening decreased from baseline after the race in both males and females, with the decrease greater in males (males: 54.1 ±2.1 to 50.7 ± 3.4% vs. females: 55.4 ± 2.7 to 53.3 ± 2.5 %). Despite no change in preload, systolic function (stress-shortening relationship) was significantly decreased in males and females following PSE. The amount of dobutamine necessary to increase HR 25 beats min⁻¹ (males: 29.6 ± 6.6 to 42.7 ± 12.9 μgkg⁻¹min⁻¹ vs. females: 23.5 ± 4.0 to 30.0 ± 7.8 ugkg⁻¹min⁻¹) and contractility 10 mmHg-cm- 2 (males: 20.9 ± 5.1 to 37.0 ±11.5 μg kg⁻¹min⁻¹ vs. females: 22.6 ± 6.4 to 30.7 ± 7.2 μg kg⁻¹ min⁻¹) was significantly greater in both males and females post-race, with the amount of drug necessary to induce this change significantly greater in males. These results provide evidence that an acute bout of PSE results in reduced LV systolic function and dobutamine responsiveness in both males and females and that these alterations occur to a greater extent in males.

description: Many farmland owners opt to work directly with farmer-tenants while others choose to hire a professional farm manager to assist in the management of their land. As absentee landownership increases and more landowners become less associated with farming, professional farm managers have increased opportunity to communicate their role to potential clientele. Some landowners have an opportunity to make the most of their situation by enlisting the services of a professional farm manager, but only if they know what can be expected from a professional farm manager. We discuss some of the benefits and disadvantages to landowners and tenants of professional farm management and how professional farm managers can convey these ideas to potential clients and assist landowners to choose the best farm manager for their farm.

description: Nonlinear metasurfaces incorporate many of the functionalities of their linear counterparts such as wavefront shaping but simultaneously they perform nonlinear optical transformations. This dual functionality leads to a rather unintuitive physical behavior which is still widely unexplored for many photonic applications. The nonlinear processes render some basic principles governing the functionality of linear metasurfaces not directly applicable, such as the superposition principle and the geometric optics approximation. On the other hand, nonlinear metasurfaces facilitate new phenomena that are not possible in the linear regime. Here, we study the imaging of objects through a dielectric nonlinear metalens. We illuminate objects by infrared light and record their generated images at the visible third-harmonic wavelengths. We revisit the classical lens theory and suggest a generalized Gaussian lens equation for nonlinear imaging, verified both experimentally and analytically. We also demonstrate experimentally higher-order spatial correlations facilitated by the nonlinear metalens, resulting in additional image features.

description: Farm enterprise analysis is a term that has traditionally been used to describe the process of determining costs associated with farm business enterprises and enterprise profitability. A key challenge to those who would know their costs has been the lack of guidance on cost accounting principles and the application of those principles to agriculture. However, that recently changed with the publication of the Farm Financial Standards Council’s Management Accounting Principles for Agricultural Producers, which has led to questions about the usefulness of enterprise analysis. The differences between the two approaches to determining costs for farm business enterprises are discussed as they relate to the usefulness of the output to managers for decision making.

description: Using Standard Euclidean Monte Carlo techniques, we discuss in detail the extraction of the glueball masses of 4-dimensional SU(3) lattice gauge theory in the Hamiltonian limit, where the temporal lattice spacing is zero. By taking into account the renormalization of both the anisotropy and the Euclidean coupling, we calculate the string tension and masses of the scalar, axial vector and tensor states using standard Wilson action on increasingly anisotropic lattices, and make an extrapolation to the Hamiltonian limit. The results are compared with estimates from various other Hamiltonian and Euclidean studies. We find that more accurate determination of the glueball masses and the mass ratios has been achieved and the results are a significant improvement upon previous Hamiltonian estimates. The continuum predictions are then found by extrapolation of results obtained from smallest values of spatial lattice spacing. For the lightest scalar, tensor and axial vector states we obtain masses of $m_{0^{++}}=1654 \pm 83$ MeV, $m_{2^{++}}=2272\pm 115$ MeV and $m_{1^{+-}}=2940\pm 165$ MeV, respectively. These are consistent with the estimates obtained in the previous studies in the Euclidean limit. The consistency is a clear evidence of universality between Euclidean and Hamiltonian formulations. From the accuracy of our estimates, we conclude that the standard Euclidean Monte Carlo method is a reliable technique for obtaining results in the Hamiltonian version of the theory, just as in Euclidean case.

description: The choroid, a highly vascular layer behind the retina, is an extension of the central nervous system and has parallels with the renal cortex, with blood flow far exceeding that of the brain and kidney. Thus, there has been growing interest of choroidal blood flow reflecting physiological status of systemic disease. Optical coherence tomography (OCT) enables high-resolution imaging of the choroid, but conventional analysis methods remain manual or semi-automatic, limiting reproducibility, standardisation and clinical utility. In this thesis, I develop several new methods to analyse the choroid in OCT image sequences, with each successive method improving on its predecessors. I first develop two semi-automatic approaches for choroid region (Gaussian Process Edge Tracing, GPET) and vessel (Multi-scale Median Cut Quantisation, MMCQ) analysis, which improve on manual approaches but remain user-dependent. To address this, I introduce DeepGPET, a deep learning-based region segmentation method which improves on execution time, reproducibility, and end-user accessibility, but lacks choroid vessel analysis and automatic feature measurement. Improving on this, I developed Choroidalyzer, a deep learning-based pipeline to segment the choroidal space and vessels and generate fully automatic, clinically meaningful and reproducible choroidal features. I provide rigorous evaluation of these four approaches and consider their potential clinical value in three applications into systemic health: OCTANE, assessing choroidal changes in renal transplant recipients and donors; PREVENT, exploring choroidal associations with Alzheimer's risk factors at mid-life; D-RISCii, assessing choroidal variation and feasibility of OCT in critical care. In short, this thesis contributes many open-source tools for standardised choroidal measurement and highlights the choroid's potential as a biomarker in systemic health.

description: We present results for the evolution of the abundances of heavy elements (O, Mg, Al, Si, K, Ca, Cr, Mn, Ni and Fe) in the inner Galactic regions ($R_{GC} < 4$kpc). We adopt a detailed chemical evolution model already tested for the Galactic bulge and compare the results with APOGEE data. We start with a set of yields from the literature which are considered the best to reproduce the abundance patterns in the solar vicinity. We find that in general the predicted trends nicely reproduce the data but in some cases either the trend or the absolute values of the predicted abundances need to be corrected, even by large factors, in order to reach the best agreement. We suggest how the current stellar yields should be modified to reproduce the data and we discuss whether such corrections are reasonable in the light of the current knowledge of stellar nucleosynthesis. However, we also critically discuss the observations. Our results suggest that Si, Ca, Cr and Ni are the elements for which the required corrections are the smallest, while for Mg and Al moderate modifications are necessary. On the other hand, O and K need the largest corrections to reproduce the observed patterns, a conclusion already reached for solar vicinity abundance patterns, with the exception of oxygen. For Mn we apply corrections already suggested in previous works. \end{abstract}

description: Weekly grid market share by volume for slaughter steers is compared to slaughter heifers. Summary statistics indicate average grid market share for steers (42%) is 27% higher than slaughter heifers (33%). The literature indicates that pregnancy and increased dark cutter incidence associated with heifers relative to steers creates additional financial risk when heifers are sold on a grid. Econometric analysis suggests grid market share is less sensitive to change in market conditions for heifers relative to steers. The empirical evidence is consistent with the supposition that marketing heifers is riskier than marketing steers on a grid. Thus sellers need stronger economic incentives to market heifers on a grid relative to steers.

description: Service-orientation is a promising paradigm that enables the engineering of large-scale distributed software systems using rigorous software development processes. The existing problem is that every service-oriented software development project often requires a customized development process that provides specific service-oriented software engineering tasks in support of requirements unique to that project. To resolve this problem and allow situational method engineering, we have defined a set of method fragments in support of the engineering of the project-specific service-oriented software development processes. We have derived the proposed method fragments from the recurring features of eleven prominent service-oriented software development methodologies using a systematic mining approach. We have added these new fragments to the repository of OPEN Process Framework to make them available to software engineers as reusable fragments using this well-known method repository. Keyword.

description: Photometry and spectra of the type Ib SN 1990I are presented and analysed, covering about 400 days of evolution. The presence of optical helium lines is shown. SN 1990I seems to show higher velocities compared to a sample of type Ib events. The nebular emission lines display a high degree of asymmetry and the presence of fine structures. Using the [O I] 6300,64A flux, we estimate a lower limit on the oxygen mass to fall in the range (0.7-1.35) M_solar. The oxygen mass requires a filling factor as small as 10^{-2} on day 254, indicating a highly clumpy distribution of the oxygen material. A blueshift of the order 600 km/s is reported in the [O I] 6300,64A after day 254. The [Ca II] 7307.5A emission profile appears blueshifted as well at late epochs . We recover the quasi-bolometric "BVRI" light curve of SN 1990I. The constructed bolometric light curve shows a change of slope at late phases, with an e-folding time of 60 +/-2 d in the [50:200] d time interval, considerably faster than the one of {56}Co decay (i.e. 111.3 d), suggesting the gamma-rays escape with lower deposition, owing to the low mass nature of the ejecta. After day 200, an $e$-folding time ~47 +/-2.8 d is measured. A simplified gamma-ray deposition model is applied after adding a contribution of about 35% to the computed pseudo-bolometric light curves to account for near-IR luminosities to estimate the ejecta and {56}Ni masses (M({56}Ni)=0.11 M_solar and M_{ej}=3.7 M_solar). The deficit in luminosity is estimated to be about 50% around day 308. The observed spectral blueshift combined with the dramatic and sudden drop in the pseudo-bolometric light curve and (B-V) colour is interpreted to be a consequence of dust condensation in the ejecta of SN 1990I around day 250.

description: We study a special two-dimensional dilaton gravity with Lagrangian $\mathcal{L}=\frac{1}{2}\sqrt{-g}(ϕR+{λ^2}{\rm sech}^2ϕ)$ where $λ$ is a parameter of dimension mass. This theory describes two-dimensional spacetimes that are asymptotically flat. Very interestingly, it has an exact solution for the metric, $\d s^2=-(c+\tanh λx)\d t^2+ \d x^2/(c+\tanh λ x)$, parametrized by $c$. For $c\in(-1,1)$, the solution presents an event horizon but no singularity. Because of the kink profile for the metric components appearing in the solution, we refer to the spacetime described by the metric as a {\it gravitational domain wall} with the wall simply being the event horizon and separating two asymptotically Minkowskian spacetimes. The global causal structure for such an object is studied via coordinate extension and the thermodynamical quantities are computed. Only when $c\in(-1,0]$ are the entropy and energy non-negative.

description: The smallest spot in optical lithography and microscopy is generally limited by diffraction. Quantum lithography, which utilizes interference between groups of N entangled photons, was recently proposed to beat the diffraction limit by a factor N. Here we propose a simple method to obtain N photons interference with classical pulses that excite a narrow multiphoton transition, thus shifting the "quantum weight" from the electromagnetic field to the lithographic material. We show how a practical complete lithographic scheme can be developed and demonstrate the underlying principles experimentally by two-photon interference in atomic Rubidium, to obtain focal spots that beat the diffraction limit by a factor of 2.

description: This study proposes a novel approach to estimating a recreational demand model that accounts for intra-household resource allocation. The technique is based on an analogy borrowed from the literature of collective household behavior and, in particular, on Browning, Chiappori and Lewbel (2006)’s model. We formulate a collective recreational demand model that takes into account the role of each member’s preferences for consumption choices and that depends on how disposable income is divided within the household. This model identifies the Consumer Surplus for each household member and the allocation of resources within a household by a consumption technology function, which summarizes all of the technological economies of scale and scope that result from living together, and by using information about the consumption of individuals living alone as if they were living in a household. Finally, we show that husbands and wives have significantly different recreational demands. This implies that observations for husbands and wives may not be treated as identical as in the traditional recreational demand model (unless one spouse is the dictator) and that the collective setting is a plausible next step to take in the analysis of recreational demand models.

Subsequently, the Euler characteristic of a triangulation, the Gauss-Bonnet theorem and the Poincaré-Hopf theorem are compared. This results in theorems which are proved using combinatorial, topological and geometric approaches. The work is restricted to regions in ℝ^2 so that the proofs can be carried out by using elementary multivariable calculus.

description: The recent RCNP $(α, α')$ data on the Isoscalar Giant Monopole Resonance (ISGMR) and Isoscalar Giant Quadrupole Resonance (ISGQR) in $^{92,94,96,98,100}$Mo are analyzed within a fully self-consistent Quasiparticle Random Phase Approximation (QRPA) approach with Skyrme interactions, in which pairing correlations and possible axial deformations are taken into account. The Skyrme sets SkM*, SLy6, SVbas and SkP$^δ$, that explore a diversity of nuclear matter properties, are used. We discuss the connection between the line shape of the monopole strength ISGMR and the deformation-induced coupling between the ISGMR and the $K=0$ branch of the ISGQR. The ISGMR centroid energy is best described by the force SkP$^δ$, having a low incompressibility $K_{\infty}$ = 202 MeV. The ISGQR data are better reproduced by SVbas, that has large isoscalar effective mass $m^*/m$ = 0.9. The need of describing simultaneously the ISGMR and ISGQR data is stressed, with the requirement of suitable values of $K_\infty$ and $m^*/m$. Possible extensions of the QRPA to deal with soft systems are also envisaged.

description: Cost-benefit analyses of health and safety regulations require estimates of the benefits of reducing pollution, and hence the risks of pollution-caused illnesses. Lost work income constitutes an important component of monetized benefits. This paper examines the impact of married men and women’s health conditions potentially caused or exacerbated by environmental exposures on their labor force participation, hours of work, and weekly earnings. I focus on cancer, stroke, ischemic heart disease, emphysema, chronic bronchitis, chronic obstructive pulmonary disease and asthma. The analysis is based on data from the Medical Expenditure Panel Survey for U.S. households from 1996 to 2002.
Roles of non-equilibrium conduction electrons on magnetization dynamics of ferromagnets

description: The mutual dependence of spin-dependent conduction and magnetization dynamics of ferromagnets provides the key mechanisms in various spin-dependent phenomena. We compute the response of the conduction electron spins to a spatial and time varying magnetization ${\bf M} ({\bf r},t)$ within the time-dependent semiclassical transport theory. We show that the induced non-equilibrium conduction spin density in turn generates four spin torques acting on the magnetization--with each torque playing different roles in magnetization dynamics. By comparing with recent theoretical models, we find that one of these torques that has not been previously identified is crucial to consistently interpret experimental data on domain wall motion.

The accuracy is calculated by looking at whether for each trial the key press (exp.test.keyr) match the target location (exp.test.target_loc) in the *_test.mat files, following this mapping:For Exp 1, key 1 = 28, 2 = 29, 3 = 30, 4 = 31, 5 = 32, 6 = 33.For Exp 2: key 1 = 35, 2 = 34, 3 = 33, 4 = 28, 5 = 29, 6 = 30.
Dependency analysis:For within-event dependency analysis, the accuracy data is arranged in a MxN matrix of M 'events' and N 'retrieval trials’ (and corresponds to variable ‘res’ in the script). For across-events dependency analysis, the accuracy data is paired so that accuracy for both events from a pair is in the same row, creating a Mx2N matrix of M pairs of matched ’events' and 2N 'retrieval trials’ (i.e. row 1 contains accuracy on retrieval trials for both event1 and event2).
Retrieval trials (N = 6) are arranged in the following order (first item is the cue, second item is the target):1: person + location2: person + object3: location + object4: location + person5: object + person6: object + location
To calculate the contingency tables for within-event dependency, we use the following pairs of events (each row = one pair):pairs_within = [1 2; 3 4; 5 6; 4 5; 1 6; 2 3]; % first three are for same cue (AbAc), last three for same target (BaCa)To calculate the contingency tables for within-event dependency, we use the following pairs of events (removing those where the cue and/or target is common to both events):pairs_across = [1 7; 2 8; 3 9; 4 10; 5 11; 6 12; ... % same cue and target (Ab(i)Ab(ii) and Ba(i)Ba(ii)) 1 8; 2 7; 3 10; 4 9; 5 12; 6 11; ... % Ab(i)Ac(ii) 4 11; 5 10; 1 12; 6 7; 2 9; 3 8]; % Ba(i)Ca(ii)Each of these pairs in turn is used as the variable ‘pair’ in the script.

description: This paper analyzed the effects of the U.S. domestic offset program on the world cotton markets using a partial equilibrium model following the assumption given by Brown et al. (2010). The results in our study are largely similar to those of Baker et al. and Brown et al., confirming that study’s findings that ACES, and its domestic offset program in particular, would cause increases in the domestic prices of several agricultural commodities. However, the overall effects of this increase in the world price on total world trade is tempered by increased exports from India, Brazil, Uzbekistan, Australia, and Western & Central African countries.
Pericardial-mediated diastolic ventricular interactions in endurance-trained athletes during orthostatic stress
Creators: name: Esch, Ben Thomas Alexander.
Publisher: name: University of British Columbia
Year: 2009

description: Purpose: To assess diastolic ventricular interaction (DVI) and its consequences in endurance athletes and normally active individuals during lower body positive (LBPP) and negative pressure (LBNP). Methods: Eight male endurance athletes (VO₂ max 65.4 ± 5.7 mL•kg⁻¹•min⁻¹) and eight normally active individuals (VO₂ max 45.1 ± 6.0 mL•kg⁻¹•min⁻¹) underwent three experimental days: 1) assessment of VO₂ max 2) a negative orthostatic tolerance test, and 3) LBPP (0 to 60 mmHg) and LBNP (0 to -80 mmHg) during which time ventricular volumes were examined via echocardiography. Results: All normally active individuals completed the tolerance test on experimental day two, but seven out of eight athletes did not complete this test due to signs of presyncope. There were no statistically significant differences between groups in resting left ventricular end-diastolic volume (LVEDV), stroke volume, or cardiac output. In response to LBNP on experimental day three there was a similar decrease in right ventricular (RV) end-diastolic area in both groups. However, there was a differential group response to LBNP (a greater decrease in the endurance athletes) during day three with respect to LVEDV (p<0.05). The endurance athletes also had significantly greater decreases in stroke volume and cardiac output during LBNP compared to the normally active group (p<0.05). During LBPP on day three, the endurance athletes showed greater increases in LVEDV and stroke volume, despite similar responses in RV end diastolic area (p<0.05). Conclusion: Endurance athletes likely had a relatively slack pericardium causing minimized DVI during conditions of orthostatic stress, whereas the normally active individuals appear to have more marked DVI during orthostatic stress which allows for a paradoxically greater maintenance of LV filling in response to LBNP.

description: Walking and cycling are promoted to encourage sustainable travel behavior among children and adults. School children during their travel episode to-and-from school are disproportionately exposed to air pollution due to multiple reasons such as proximity to high traffic roads and peak volumes. This paper presents a route to school informational intervention that was developed incorporating approaches and methods suggested in the literature for effective behavioral interventions. The intervention was implemented using escorting parents/guardians (N=104) of school children of Antwerp, Belgium to adopt school routes with least exposure to pollutants. Collected data and its analysis revealed that 60% participants (N= 62) could benefit themselves by adopting the suggested cleanest routes to school, of whom a significant proportion of participants (i.e. 34%, N= 35) have a difference of average NO2 concentration between the alternative and current route of around 10μg/m3. This information about alternatives routes with their potential benefits was presented to each participant via defined study protocols. 18 Based on the feedback of participants that could potentially adopt suggested alternatives, 77% (N=48) have switched their routes. These results indicated that intervention was effective, and it can bring higher benefits when implemented on a wider scale.

description: Within Ginzburg-Landau theory, we study the structure of a magnetic vortex in color-flavor locked quark matter. This vortex is characterized by winding of the SU(3) phase in color-flavor space, as well as by the presence of a color-flavor unlocked condensate in the core. We estimate the upper and lower critical fields and the critical Ginzburg-Landau parameter that distinguishes between type I and type II superconductors.

The Prospect of Migration, Sticky Wages, and "Educated Unemployment"

description: An increase in the probability of work abroad, where the returns to schooling are higher than at home, induces more individuals in a developing country to acquire education, which leads to an increase in the supply of educated workers in the domestic labor market. Where there is a sticky wage-rate, the demand for labor at home will be constant. With a rising supply and constant demand, the rate of unemployment of educated workers in the domestic labor market will increase. Thus, the prospect of employment abroad causes involuntary “educated unemployment” at home. A government that is concerned about “educated unemployment” and might therefore be expected to encourage unemployed educated people to migrate will nevertheless, under certain conditions, elect to restrict the extent of the migration of educated individuals.
