description: In this paper, we study inference for high-dimensional data characterized by small sample sizes relative to the dimension of the data. In particular, we provide an infinite-dimensional framework to study statistical models that involve situations in which (i) the number of parameters increase with the sample size (that is, allowed to be random) and (ii) there is a possibility of missing data. Under a variety of tail conditions on the components of the data, we provide precise conditions for the joint consistency of the estimators of the mean. In the process, we clarify and improve some of the recent consistency results that appeared in the literature. An important aspect of the work presented is the development of asymptotic normality results for these models. As a consequence, we construct different test statistics for one-sample and two-sample problems concerning the mean vector and obtain their asymptotic distributions as a corollary of the infinite-dimensional results. Finally, we use these theoretical results to develop an asymptotically justifiable methodology for data analyses. Simulation results presented here describe situations where the methodology can be successfully applied. They also evaluate its robustness under a variety of conditions, some of which are substantially different from the technical conditions. Comparisons to other methods used in the literature are provided. Analyses of real-life data is also included.

The adoption and rejection of innovations by dairymen in the Lower Fraser Valley
Creators: name: Gubbels, Peter Martin
Publisher: name: University of British Columbia
Year: 2011

description: This study analyses the adoption and rejection of some dairy farm innovations by Lower Fraser Valley dairymen. It also analyses use of information sources, length of time spent in the adoption process, reasons for delay in proceeding through the adoption process, reasons for rejection and discontinuance of innovations, and dairyman-district agriculturist contact. Data for the analysis were collected by interviewing a representative sample of the Lower Fraser Valley dairymen. There was a distinct tendency for the earlier adopters to have large farms, a high production per cow, less than 20 years farming experience, a high farm plus off-farm employment income, large numbers of dairy young stock, office visits with the district agriculturist, agriculture courses at vocational schools, and enjoyment from dairying. There were no significant differences between the earlier and later adopters regarding age, years of school completed, social participation, tenure, specialization, use of hired labour and place of birth. A number of the respondents had had no contact of any type with the district agriculturist in the year previous to the interview but on the average each respondent used 2.53 types of contact. When classified by the nature of the activity, the most used sources of information were personal, followed by individual instructional, mass and instructional group. When classified by origin, the most to least used sources were personal, commercial, government and farm organization. The proportions in which the information sources were used for the two groups of innovations differed. On the average each respondent was unaware of 2.19 of the 10 innovations and continuing in the adoption process for 1.57. Rejection had occurred for an average of 4.38, adoption for 1.66 and discontinuance for 0.20 of the 10 innovations. Almost half the decisions to reject innovations were made at the awareness stage in the adoption process. From the laggard to the early adopter-innovator category, unawareness and rejection decreased while continuation in the adoption process, adoption and discontinuance increased. Situational factors made up more than two-thirds the reasons for delay in proceeding through the adoption process but characteristics of the innovations made up more than two-thirds the reasons for rejection and discontinuance of innovations. The rate of rejection and discontinuance was higher and adoption lower when less than one year was spent than when one or more years was spent in the adoption process. An adoption tendency score was derived and compared with the adoption score but it could not be determined that use of one or the other was a more useful way of identifying differences among the respondents.
The effects of increased soil temperature on Phosphorus (P) availability in Tasmanian soils
Creators: name: Coad, HM
Publisher: name: University of Tasmania
Year: 2024

description: The dependency of P fertilisers has increased to counteract P deficient soils and increase soil productivity, particularly in Tasmania to achieve a $10 billion annual net valued agricultural sector by 2050. However, the effects of extreme climatic conditions due to human-induced climate change on P availability has been insufficiently studied in comparison to other soil nutrients such as nitrogen. Forecasting movement of P throughout the soil based on specific conditions not only advances current knowledge but will allow appropriate P management strategies to be implemented. Currently it is known that increased soil temperature will cause P availability to decline. However, no studies have attributed this relationship to human-induced climate change nor soil mineralogy. Here we show that increasing soil temperature of a Tasmanian Ferrosol and Dermosol to 45 ℃ causes the rate of sorption to increase, resulting in over 50% of applied P to be sorbed by day 15 in both soil types. Although the Ferrosol and Dermosol displayed similar P sorption trends, the magnitude in which it occurred at has been attributed to differences in soil mineralogy. We also found that the deposition of P in the Ferrosol was comparable with other studies, while higher temperatures caused the behaviour of the Dermosol to become unpredictable. Understanding these effects allows both soils to be treated as two separate systems to enable optimal P availability to be achieved. This can allow P inputs and specific management strategies to be implemented to maintain Colwell P, reduce P losses to the environment and reduce the reliance on costly P fertiliser inputs while maintaining, if not increasing agricultural productivity.

description: We present the first measurement of the energy spectrum up to 70 MeV of electrons from the decay of negative muons after they become bound in $^{27}$Al atoms. The data were taken with the TWIST apparatus at TRIUMF. We find a muon lifetime of (864.6 $\pm$ 1.2) ns, in agreement with earlier measurements. The asymmetry of the decay spectrum is consistent with zero, indicating that the atomic capture has completely depolarised the muons. The measured momentum spectrum is in reasonable agreement with theoretical predictions at the higher energies, but differences around the peak of the spectrum indicate the need for \oalpha radiative corrections to the calculations. The present measurement is the most precise measurement of the decay spectrum of muons bound to any nucleus.
Brownian motion conditioned to stay in a cone

description: A result of R. Durrett, D. Iglehart and D. Miller states that Brownian meander is Brownian motion conditioned to stay positive for a unit of time, in the sense that it is the weak limit, as $x$ goes to 0, of Brownian motion started at $x>0$ and conditioned to stay positive for a unit of time. We extend this limit theorem to the case of multidimensional Brownian motion conditioned to stay in a smooth convex cone.
On the chains of star complexes and superclouds in spiral arms

Subjects: subject: Cosmology and Nongalactic Astrophysics (astro-ph.CO)
subject: FOS: Physical sciences

description: The relation is studied between occurrence of a regular chain of star complexes and superclouds in a spiral arm, and other properties of the latter. A regular string of star complexes is located in the north-western arm of M31; they have about the same size 0.6 kpc with spacing of 1.1 kpc. Within the same arm segment the regular magnetic field with the wavelength of 2.3 kpc was found by Beck et al. (1989). We noted that this wavelength is twice as large as the spacing between complexes and suggested that they were formed in result of magneto-gravitational instability developed along the arm. In this NW arm, star complexes are located inside the gas-dust lane, whilst in the south-western arm of M31 the gas-dust lane is upstream of the bright and uniform stellar arm. Earlier, evidence for the age gradient has been found in the SW arm. All these are signatures of a spiral shock, which may be associated with unusually large (for M31) pitch-angle of this SW arm segment. Such a shock may prevent the formation of the regular magnetic field, which might explain the absence of star complexes there. Anti-correlation between shock wave signatures and presence of star complexes is observed in spiral arms of a few other galaxies. Regular chains of star complexes and superclouds in spiral arms are rare, which may imply that a rather specific mechanism is involved in their formation, and the most probable one is the Parker-Jeans instability. The spiral pattern of our Galaxy is briefly discussed; it may be of M101 type in the outer parts. The regular bi-modal spacing of HI superclouds is found in Carina and Cygnus (Outer) arms, which may be an indirect evidence for the regular magnetic field along these arms.

description: To conduct a cost-effectiveness analysis (CEA) on the use of andexanet alfa for the treatment of factor Xa inhibitor-related intracranial hemorrhage (ICH) from the United States (US) third-party payer and societal perspectives. CEA compared andexanet alfa to prothrombin complex concentrate (PCC) for the treatment of patients receiving factor Xa inhibitors admitted to hospital inpatient care with an ICH. The model comprised two linked phases. Phase 1 utilized a decision tree to model the acute treatment phase (admission of a patient with ICH into intensive care for the first 30 days). Phase 2 modeled long-term costs and outcomes using three linked Markov models comprising the six health states defined by the modified Rankin score. The analysis showed that the strategy of using andexanet alfa for the treatment of factor Xa inhibitor–related ICH is cost-effective, with incremental cost-effectiveness per quality-adjusted life-year gained of $35,872 from a third-party payer perspective and $40,997 from a societal perspective over 20 years. (1) Absence of head-to-head trials comparing therapies included in the economic model, (2) lack of comparative long-term data on treatment efficacy, and (3) bias resulting from the study designs of published literature. Given these results, the use of andexanet alfa for the reversal of anticoagulation in patients with factor Xa inhibitor–related ICH may improve quality of life and is likely to be cost-effective in a US context.
Determination of the Neutrino Flavor Ratio at the Astrophysical Source

description: We discuss the reconstruction of neutrino flavor ratios at astrophysical sources through the future neutrino-telescope measurements. Taking the ranges of neutrino mixing parameters $θ_{ij}$ as those given by the current global fit, we demonstrate by a statistical method that the accuracies in the measurements of energy-independent ratios $R\equivϕ(ν_μ)/(ϕ(ν_{e})+ϕ(ν_τ))$ and $S\equivϕ(ν_e)/ϕ(ν_τ)$ among integrated neutrino flux should both be better than 10% in order to distinguish between the pion source and the muon-damped source at the $3 σ$ level. The 10% accuracy needed for measuring $R$ and $S$ requires an improved understanding on the background atmospheric neutrino flux to a better than 10% level in the future. We discuss the applicability of our analysis to practical situations that the diffuse astrophysical neutrino flux arises from different types of sources and each point source has a neutrino flavor ratio varying with energies. We also discuss the effect of leptonic CP phase on the flavor-ratio reconstruction.

Physical Conditions in the Low-Ionization Component of Starburst Outflows: The Shape of Near-Ultraviolet and Optical Absorption-Line Troughs in Keck Spectra of ULIRGs

description: We analyze the physical conditions in the low-ionization component of starburst outflows (in contrast to the high-ionization wind fluid observed in X-rays), based on new Keck/LRIS spectroscopy of partially resolved absorption troughs in near-ultraviolet and optical spectra of Ultraluminous Infrared Galaxies. The large velocity width and blueshift present in seven, atomic transitions indicate a macroscopic velocity gradient within the outflowing gas. The \mgII 2796, 2803 (and \feII 2587, 2600) doublet lines in these data constrains the gas kinematics better than the heavily blended \nad 5892, 98 doublet. The identical shape of the \mgII 2796 absorption troughs to that of the normally weaker transition at 2803Årequires both transitions be optically thick at all outflow velocities. The fraction of the galactic continuum covered by the outflow at each velocity therefore dictates the shape of these absorption troughs. We suggest that the velocity offset of the deepest part of the troughs, where the covering factor of low-ionization gas is near unity, reflects the speed of a shell of swept-up, interstellar gas at the time of blowout. In a spherical outflow, we show that the fragments of this shell expand slowly relative to the geometrical dilution; and the covering fraction of low-ionization gas decreases with increasing radius. Our measurement of a covering factor that decreases with increasing velocity can therefore be interpreted as evidence that the low-ionization outflow is accelerating. We also present measurements of C_f(v) in 4 species, place an upper limit of 3000 cm3 on the density of the outflowing gas, and discuss lower limits on the mass outflow rate.

description: The dynamics of prominence fine structures is a challenge to understand the formation of cool plasma prominence embedded in the hot corona. Recent observations from the high resolution Hinode/SOT telescope allow us to compute velocities perpendicularly to the line-of-sight or transverse velocities. Combining simultaneous observations obtained in H-alpha with Hinode/SOT and the MSDP spectrograph operating in the Meudon solar tower we derive the velocity vectors of a quiescent prominence. The velocities perpendicular to the line-of-sight are measured by time slice technique, the Dopplershifts by the bisector method. The Dopplershifts of bright threads derived from the MSDP reach 15 km/s at the edges of the prominence and are between +/- 5 km/s in the center of the prominence. Even though they are minimum values due to seeing effect, they are of the same order as the transverse velocities. These measurements are very important because they suggest that the verticalstructures shown in SOT may not be real vertical magnetic structures in the sky plane. The vertical structures could be a pile up of dips in more or less horizontal magnetic field lines in a 3D perspective, as it was proposed by many MHD modelers. In our analysis we also calibrate the Hinode H-alpha data using MSDP observations obtained simultaneously.

description: Given the high number of refugee children and adolescents around the globe, it is critical to determine conditions that foster their adaptation in the receiving country. This study investigated the psychological adaptation of recently arrived adolescent refugees in Germany. We focused on whether psychological adaptation reflects the organizational approach taken by the school that refugee adolescents initially attended. School is an important context for the development and acculturation of young refugees. As in other European countries, the schooling of refugee adolescents in Germany is organized in different models: separate instruction in newcomer classes, direct immersion in regular classes, and mixed approaches. To answer our research questions, we used self-reported data from 700 refugee adolescents (12-, 14-, and 17-year-olds) in a representative survey of refugees in Germany. As indicators of their psychological adaptation, we analyzed their sense of school belonging, their emotional and behavioral problems, and their life satisfaction. Comparing them to non-refugee peers, the refugee adolescents showed similar levels of psychological adaptation, and an even higher level in the case of school belonging. Multiple regression analyses provide limited support for the assumed advantage of the mixed school organizational model: While students who initially attended a mixed approach reported higher levels of school belonging than those in other models, no differences emerged on the other indicators. We discuss the implications of our findings for the schooling of newly arrived refugees.
The importance of population density in broiler production
Creators: name: Hamilton, Douglas Malcolm
Publisher: name: University of British Columbia
Year: 2011

description: Commercial broiler chickens were reared as combined sexes at floor space areas of 0.6, 0.7, 0.8, 0.9 and 1.0 ft.2 per bird to ten weeks of age. There was no significant difference in the mean body weights at nine weeks of age. At ten weeks of age, there was no significant difference in the mean body weights of the birds reared at 0.7, 0.8, 0.9 and 1.0 ft.² per bird, while the floor area of 0.6 ft.² per bird produced significantly lighter birds than did 1.0 ft.² Mortality was not affected by bird density, whereas the percentage of breast blisters increased with increasing density. Broiler production costs and various combinations of feed and meat prices were used in models to determine the age at which maximum annual net returns per square foot of floor area occurred. Assuming that the weekly mean body weights were the same for birds grown at 0.7 and 1.0 ft.² per bird floor area, maximum net returns were obtained by marketing at nine or ten weeks of age depending on feed and meat prices. The effect on net returns of marketing one week earlier or later than at the age of greatest net returns was examined. When it was assumed that the number of lots per year was limited to 4.33 i.e. a twelve week replacement program, annual maximum net returns were found to occur at a market age of at least ten weeks. When the number of lots marketed was not assumed to be limited, annual maximum returns also occurred, with few exceptions, at least at ten weeks of age.

description: The achievement of local cooling is a prominent goal in the design of functional transport nanojunctions. One generic mechanism for local cooling is driving a system through a local uphill potential step. In this paper we examine the manifestation of this mechanism in the context of the Kramers barrier crossing problem. For a particle crossing a barrier, the local effective temperature and the local energy exchange with the thermal environment are calculated, and the coefficient of performance of the ensuing cooling process is evaluated.

description: Many disciplines make use of mathematical concepts. However, there are often discrepancies between the way mathematical concepts are understood and taught in mathematics and the way they are used in other disciplines. The literature suggests that such discrepancies might make it hard for students in mathematics service courses to make a connection between the mathematical concepts taught and the way they are used in the students’ major disciplines. We investigated this hypothesis for one specific example in mathematics for economics students – the derivative and its interpretation commonly used in economics as the amount of change when increasing the production by one unit. We conducted an interview study investigating to what extent economics students can make a connection between the mathematical concept of the derivative and this common economic interpretation of the derivative. This study provides empirical evidence that it is actually difficult for economics students to make this connection, even though it was covered in their calculus course. In particular, the study reveals difficulties students have when trying to make this connection, which could be addressed in teaching.

description: We generalize a recently proposed on-shell approach to renormalize the Cabibbo-Kobayashi-Maskawa quark-mixing matrix to the case of an extended leptonic sector that includes Dirac and Majorana neutrinos in the framework of the seesaw mechanism. An important property of this formulation is the gauge independence of both the renormalized and bare lepton mixing matrices. Also, the texture zero in the neutrino mass matrix is preserved.

description: Ratchets are dynamic systems where particle transport is induced by zero-average forces due to the interplay between nonlinearity and asymmetry. Generally, they rely on the effect of a strong external driving. We show that stationary optical lattices can be designed to generate particle flow in one direction while requiring neither noise nor driving. Such optical fields must be arranged to yield a combination of conservative (dipole) and nonconservative (radiation pressure) forces. Under strong friction all paths converge to a discrete set of limit periodic trajectories flowing in the same direction.

Automation of next-to-leading order computations in QCD: the FKS subtraction

description: We present the complete automation of the universal subtraction formalism proposed by Frixione, Kunszt, and Signer for the computation of any cross section at the next-to-leading order in QCD. Given a process, the only ingredient to be provided externally is the infrared- and ultraviolet-finite contribution of virtual origin. Our implementation, currently restricted to the case of e+e- collisions, is built upon and works in the same way as MadGraph. It is particularly suited to parallel computation, and it can deal with any physical process resulting from a theory implemented in MadGraph, thus including the Standard Model as well as Beyond the Standard Model theories. We give results for some sample processes that document the performances of the implementation, and show in particular how the number of subtraction terms has an extremely mild growth with final-state multiplicity.

description: Using the methods of general relativity Lindquist derived the radiative transfer equation that is correct to all orders in v/c. Mihalas developed a method of solution for the important case of monotonic velocity fields with spherically symmetry. We have developed the generalized atmosphere code PHOENIX, which in 1-D has used the framework of Mihalas to solve the radiative transfer equation (RTE) in 1-D moving flows. We describe our recent work including 3-D radiation transfer in PHOENIX and particularly including moving flows exactly using a novel affine method. We briefly discuss quantitative spectroscopy in supernovae.

description: Gluinos are produced pairwise at the LHC in quark-antiquark and gluon-gluon collisions: $qqbar,gg \to \tilde{g} \tilde{g}$. While the individual polarization of gluinos vanishes in the limit in which the small mass difference between L and R squarks of the first two generations is neglected, non-zero spin-spin correlations are predicted within gluino pairs. If the squark/quark charges in Majorana gluino decays are tagged, the spin correlations have an impact on the energy and angular distributions in reconstructed final states. On the other hand, the gluino polarization in single gluino production in the supersymmetric Compton process $g q \to \tilde{g} \tilde{q}_{R,L}$ is predicted to be non-zero, and the polarization affects the final-state distributions in super-Compton events.
