description: We have observed in a low density two-dimensional hole system (2DHS) of extremely high quality (with hole density p=1.6x10^{10} cm^{-2} and mobility μ=0.8x10^6 cm^2/Vs) that, as the 2DHS is continuously tilted with respect to the direction of the magnetic field, the ν=1/3 fractional quantum Hall effect (FQHE) state is weakened and its magnetoresistivity rises from ~ 0.4 kohm/square in the normal orientation to ~ 180 kohm/square at tilt angle θ\~ 80 degrees. We attribute this phenomenon to the transition of the 2DHS from the FQHE liquid state to the pinned Wigner solid state, and argue that its origin is the strong coupling of subband Landau levels under the tilted magnetic fields.

description: A new paradigm is needed in extension marketing programs. Attempts to help producers time the market, either through cask sales or futures trading, appear to be of little benefit. Marketing extension programs need to place less emphasis on outlook and futures trading and more emphasis on simple marketing strategies that people really use. An empirical example of strategies for Oklahoma wheat producers shows selling cash wheat at harvest and participating in government programs as the preferred marketing strategy. Implications for extension programs in other states are that extension programs can help producers decide whether to store their grain and whether to participate in farm programs.

description: We use on-shell methods to study the non-supersymmetric and supersymmetric low-energy S-matrix on a probe D3-brane, including both the 1-loop contributions of massless states as well as the effects of higher-derivative operators. Our results include: (1) A derivation of the duality invariance of Born-Infeld electrodynamics as the dimensional oxidation of the group of spatial rotations transverse to a probe M2-brane; this is done using a novel implementation of subtracted on-shell recursion. (2) The first explicit loop-level BCJ double-copy in a non-gravitational model, namely the calculation of the 4-point self-dual amplitude of non-supersymmetric Born-Infeld. (3) From previous results for $n$-point self-dual 1-loop BI amplitudes and the conjectured dimension-shifting relations in Yang-Mills, we obtain an explicit all-multiplicity, at all orders in $ε$, expression for the 1-loop integrand of the MHV sector of $\mathcal{N}=4$ DBI. (4) For all $n>4$, the explicitly integrated duality-violating 1-loop amplitudes (self-dual and next-to-self-dual in pure BI as well as MHV in $\mathcal{N}=4$ DBI) are shown to be removable at $\mathcal{O}(ε^0)$ by adding finite local counterterms; we propose that this may be true more generally at 1-loop order. (5) We find that in non-supersymmetric Born-Infeld, not all finite local counterterms needed to restore electromagnetic duality can be constructed using the double-copy with higher-derivative corrections, suggesting a fundamental tension between electromagnetic duality and color-kinematics duality at loop-level. Finally we comment on oxidation of duality symmetries in supergravity and the parallels it has to the M2-brane to D3-brane oxidation demonstrated in this paper.

description: This article examines nutrient deficiencies (below guaranteed levels) in major blended commercial fertilizers and their economic impact on net revenues of Texas farmers. Violations by fertilizer manufactures in meeting specific labeled nutrient levels were more than offset in economic value by excesses in other nutrients and by production of blends that contained more than the required levels of all nutrients. The study concluded that economic losses to Texas farmers would likely be associated with requiring nutrient levels to be more tightly distributed around the guaranteed or labeled nutrient levels.

description: Four models of energy decoherence are discussed from the common perspective of intrinsic time-uncertainty. The four authors -- Milburn, Adler, Penrose, and myself -- have four different approaches. The present work concentrates on their common divisors at the level of the proposed equations rather than at the level of the interpretations. General relationships between time-uncertainty and energy-decoherence are presented in both global and local sense. Global and local master equations are derived. (The local concept is favored.)

description: Results from a consumer-oriented study of households in Louisiana and Texas suggest that the nutritional properties of rabbit meat play a minor role in its consumption. In general, users regard rabbit meat as inferior to chicken, beef or pork and non-users are reluctant to try rabbit meat. Based on these results, the market for rabbit meat is likely to remain small, and rabbit production may not be a viable enterprise for farmers in this region of the country.

description: This Paper discusses the usefulness of the residual signal for speaker recognition. It is shown that the combination of both a measure defined over LPCC coefficients and a measure defined over the energy of the residual signal gives rise to an improvement over the classical method which considers only the LPCC coefficients. If the residual signal is obtained from a linear prediction analysis, the improvement is 2.63% (error rate drops from 6.31% to 3.68%) and if it is computed through a nonlinear predictive neural nets based model, the improvement is 3.68%.

Factors affecting the success of the futures contract are presented including the uncertainties of air pollution and public utility regulation, emission control technology, electricity demand, and electric utility needs for an allowance price discovery mechanism for long-range compliance planning under risk. If SO2 futures market is successful, there is some potential for expanding futures trading to other pollutants. Since SO2 is uniquely suited to a national market, duplication of SO2 futures for other pollutants may be difficult.

Swimming upstream : the experience of parents who choose not to immunize their children
Creators: name: Marchant-Short, Sheila Jayne
Publisher: name: University of British Columbia
Year: 2009

description: This study explored the experience of parents who have chosen not to immunize their children. Immunization is generally considered by health care professionals to be one of the most effective public health practices. There is an assumption in the immunization literature that if parents choose not to immunize their children then they must need more information, or they do not understand the risk of disease or they are following some incorrect line of reasoning. An interpretive descriptive design was used for this study of nine parents who had declined immunization for their children. Participants ranged in age from 25 to 45 years, with children ranging in age from 4 months to 12 years. All parents resided in the catchment area served by the Vancouver Island Health Authority - South Island. Data were collected by unstructured interviews and analyzed using inductive analysis. Parents reported that they sought to be well informed, they desired expert advice and they found themselves weighing conflicting choices and opinions. Parents also reported varying degrees of support from health care providers and others after making a socially unacceptable decision. And finally, parents reported their experience of learning to live with the repercussions of their decision including their perception of health care received and accessing health care services. The findings from this study have the potential of assisting health care providers to have a better understanding of the experience of parents who decided not to immunize, and how their practice potentially affects the experience of parents.

description: The competitive position of three warm-season turf species commonly grown in the South (bermudagrass, centipedegrass, and zoysiagrass) is evaluated for a farm with 100 acres available to allocate to turfgrass-sod production. A multiperiod linear programming model is used to determine optimal mixes of grasses and resulting net returns for a seven-year planning horizon. Within current observable price ranges, variation in the prices of the different grasses has little impact on the profit-maximizing combination of grasses. Bermudagrass, with the shorter production cycle and positive influence on cash flow, dominates the higher-valued, longer-production-cycle alternative grasses. Availability of initial money capital from internal sources does not alter the feasibility of bermudagrass.
Dibaryon model for nuclear force and the properties of the $3N$ system

description: The dibaryon model for $NN$ interaction, which implies the formation of an intermediate six-quark bag dressed by a $σ$-field, is applied to the $3N$ system, where it results in a new three-body force of scalar nature between the six-quark bag and a third nucleon. A new multicomponent formalism is developed to describe three-body systems with nonstatic pairwise interactions and non-nucleonic degrees of freedom. Precise variational calculations of $3N$ bound states are carried out in the dressed-bag model including the new scalar three-body force. The unified coupling constants and form factors for $2N$ and $3N$ force operators are used in the present approach, in a sharp contrast to conventional meson-exchange models. It is shown that this three-body force gives at least half the $3N$ total binding energy, while the weight of non-nucleonic components in the $^3$H and $^3$He wavefunctions can exceed 10%. The new force model provides a very good description of $3N$ bound states with a reasonable magnitude of the $σNN$ coupling constant. A new Coulomb $3N$ force between the third nucleon and dibaryon is found to be very important for a correct description of the Coulomb energy and r.m.s. charge radius in $^3$He. In view of the new results for Coulomb displacement energy obtained here for A=3 nuclei, an explanation for the long-term Nolen--Schiffer paradox in nuclear physics is suggested. The role of the charge-symmetry-breaking effects in the nuclear force is discussed.

description: The scalarization is a very interesting phenomena allowing to endow a compact object with scalar hair while leaving all the predictions in the weak field limit unaltered. In Gauss-Bonnet gravity the source of the scalar field can be the curvature of the space-time. It was recently shown that for a particular type of coupling function between the scalar field and the Gauss-Bonnet invariant, spin-induced black hole scalarization is possible. In the present paper we study this phenomenon by performing a 2+1 time evolution of the relevant linearized scalar field perturbation equation and examine the region where the Kerr black hole becomes unstable giving rise to new scalarized rotating black holes. This is more direct numerical approach to study the development of spin-induced scalarization and it can serve as an independent check of the previous results.

description: The cosmic star formation histories are evaluated for different minimum masses of the initial halo structures, with allowance for realistic gas outflows. With a minimum halo mass of 10^{7} - 10^{8} M_odot and a moderate outflow efficiency, we reproduce both the current baryon fraction and the early chemical enrichment of the IGM. The intensity of the formation rate of ``normal'' stars is also well constrained by the observations: it has to be dominated by star formation in elliptical galaxies, except perhaps at very low redshift. The fraction of baryons in stars is predicted as are also the type Ia and II supernova event rates. Comparison with SN observations in the redshift range z=0-2 allows us to set strong constraints on the time delay of type Ia supernovae (a total delay of \sim 4 Gyr is required to fit the data), the lower end of the mass range of the progenitors (2 - 8 M_odot) and the fraction of white dwarfs that reproduce the type Ia supernova (about 1 per cent). The intensity in the initial starburst of zero metallicity stars below 270 M_\odot must be limited in order to avoid premature overenrichment of the IGM. Only about 10 - 20 % of the metals present in the IGM at z = 0 have been produced by population III stars at very high z. The remaining 80 - 90 % are ejected later by galaxies forming normal stars, with a maximum outflow efficiency occurring at a redshift of about 5. We conclude that 10^{-3} of the mass in baryons must lie in first massive stars in order to produce enough ionizing photons to allow early reionization of the IGM by z \sim 15.

description: We study the formation of intermediate-mass ratio inspirals (IMRIs) triggered by the interactions between two stellar black holes (BHs) and an intermediate-mass BH (IMBH) inhabiting the centre of a dense star cluster. We exploit $N$-body models varying the IMBH mass, the stellar BH mass spectrum, and the star cluster properties. These simulations are coupled with a semi-analytic procedure to characterise the evolution of the remnant IMBH. The IMRIs formation probability attains values $\sim 5-50\%$, with larger values corresponding to larger IMBH masses. IMRIs map out the stellar BH mass spectrum, thus they might be used to unravel BH populations in star clusters harboring an IMBH. After the IMRI phase, an IMBH initially nearly maximal(almost non-rotating) tends to decrease(increase) its spin. If IMBHs grow mostly via repeated IMRIs, we show that only IMBH seeds sufficiently massive ($M_{\rm seed} > 300$ M$_\odot$) can grow up to $M_{\rm imbh} >10^3$ M$_\odot$ in dense globular clusters. Assuming that these seeds form at a redshift $z\sim 2-6$, we find that around $1-5\%$ of them would reach masses $\sim 500-1500$ M$_\odot$ at redshift $z=0$ and would exhibit low-spins, $S_{\rm imbh} < 0.2$. Measuring the mass and spin of IMBHs involved in IMRIs could help unravelling their formation mechanisms. We show that LISA can detect IMBHs in Milky Way globular clusters with a signal-to-noise ratio SNR$=10-100$, or in the Large Magellanic Cloud with an SNR$=8-40$. We provide the IMRIs merger rate for LIGO ($Γ_{\rm LIG} = 0.003-1.6$ yr$^{-1}$), LISA ($Γ_{\rm LIS} = 0.02-60$ yr$^{-1}$), ET ($Γ_{\rm ET} = 1-600$ yr$^{-1}$), and DECIGO ($Γ_{\rm DEC} = 6-3000$ yr$^{-1}$). Our simulations show that IMRIs' mass and spin encode crucial insights on the mechanisms that regulate IMBH formation and that the synergy among different detectors would enable us to fully unveil them.

description: In this study, the results of the first Moroccan experience of the introduction of an improved rehabilitation protocol after radical cystectomy for bladder cancer are presented. Materials and methods: a prospective, monocentric, comparative, observational study entitled "Enhanced Recovery After Surgery Protocol in patients undergoing radical cystectomy" for 12 months in the Urology Department B of the Avicenne University Hospital, Rabat. The goal: To evaluate the postoperative results of a national ERAS protocol adapted to the local context, including the complications and recovery times of transit and the length of hospital stay after radical cystectomy. The challenge is to optimize the structural and functional modifications caused by the cystectomy. The challenge is to minimize ileus and delays in resuming bowel function. There were no differences between the 2 groups as far as demographics characteristics are concerned. In total,40 patients were included, 17 patients in the standard protocol and 23 patients in ERAS. Recovery of intestinal function was significantly faster in the ERAS group. The median gas take-up delay in the ERAS group in the first group was 35.1 Å} 13.8 hours, while the average delay in the second group was 65.86 Å} 24.62 hours (p = <0). 0001). The average length of stay was 11.4 days vs. 9.7 days (p: 0.04) for the ERAS group. The difference in favor of the ERAS complication protocol was not significant (p = 0.41). In conclusion, introduction and application of an enhanced recovery protocol (ERAS) after cystectomy for bladder cancer allowed for better management of postoperative outcomes. It is clearly feasible in cystectomy and improve significantly the median postoperative length of stay. The ERAS program is reliable and implantable in a service with the involvement of all medical and paramedical teams.

description: Biological networks are characterized by their connectivity and topology but also by their ability to transport materials. In the case of random transportation, the efficacy is measured by the time it takes to travel between two nodes of the network. We study here the consequences of a unidirectional transport mechanism occurring in the endoplasmic reticulum (ER) network, a structure present in the cell cytoplasm. This unidirectional transport mechanism is an active-waiting transportation, where molecules have to wait a random time before being transported from one node to the next one. We develop here a general theory of transport in an active network and find an unusual network transportation, where molecules group together in redundant packets instead of being disperse. Finally, the mean time to travel between two nodes of the ER is of the order of 20 min, but is reduced to 30 s when we consider the fastest particles because it uses optimal paths. To conclude, the present theory shows that unidirectional transport is an efficient and robust mechanism for fast molecular redistribution inside the ER.

inguistic development in English, Chinese and Persian children : a longitudinal comparison
Creators: name: Keen, Carrie A.
Publisher: name: University of British Columbia
Year: 2009

description: The linguistic development of English, Chinese, and Persian elementary school students was compared in order to identify possible language-based differences in the developmental trajectory of English grammatic, semantic, and morphosyntactic knowledge. The number and type of incorrect responses on an oral cloze test was used in an error analysis of each language group. Errors were classified as grammatic, semantic, or morphosyntactic, with an additional category for instances where students did not respond or said, "I don't know". Each error category was expressed as a proportion of errors out of the number of incorrect responses. All students demonstrated similar trajectories in their semantic and grammatic development, but the Chinese students exhibited a delay in morphosyntactic knowledge relative to the English students in grades 2 and 3. Information from contrastive analyses is used to explain the apparent languagebased morphosyntactic error pattern of the Chinese students, and pedagogical implications of the results of the study are discussed.

description: 6G is a promising communication technology that will dominate the entire health market from 2030 onward. It will dominate not only health sector but also diverse sectors. It is expected that 6G will revolutionize many sectors including healthcare. Healthcare will be fully AI-driven and dependent on 6G communication technology, which will change our perception of lifestyle. Currently, time and space are the key barriers to health care and 6G will be able to overcome these barriers. Also, 6G will be proven as a game changing technology for healthcare. Therefore, in this perspective, we envision healthcare system for the era of 6G communication technology. Also, various new methodologies have to be introduced to enhance our lifestyle, which is addressed in this perspective, including Quality of Life (QoL), Intelligent Wearable Devices (IWD), Intelligent Internet of Medical Things (IIoMT), Hospital-to-Home (H2H) services, and new business model. In addition, we expose the role of 6G communication technology in telesurgery, Epidemic and Pandemic.

description: Populations with lower extremity muscle weakness have difficulty performing the sit-to-stand (STS) transfer. The degree of weakness that can be tolerated before compromising the ability to perform this task is unknown. Using dynamic simulations, we investigated the effects of weakness before changes in kinematics/kinetics would be required. Lower extremity muscles were weakened globally and individually and muscle forces were re-estimated as the model tracked original task kinematics/kinetics. The STS transfer was sensitive to quadriceps and plantarflexor weakness, suggesting that strengthening these muscles or changing kinematics are essential for populations who have difficulty rising from a chair independently.

description: This article describes the relative size of the green industry within the U.S. economy and how it is linked to supporting industries through the volume of transactions and economic impact multipliers. This analysis was based on IMPLAN, an input-output model developed by the U.S. Forest Service. In terms of 1990 employment, the green industry was the second leading employer in United States production agriculture. In terms of output, the greenhouse and products sector ranked sixth within production agriculture, behind cattle, other livestock, grains, other crops and oil bearing crops.

Stable Facts, Relative Facts

description: Facts happen at every interaction, but they are not absolute: they are relative to the systems involved in the interaction. Stable facts are those whose relativity can effectively be ignored. In this work, we describe how stable facts emerge in a world of relative facts and discuss their respective roles in connecting quantum theory and the world. The distinction between relative and stable facts resolves the difficulties pointed out by the no-go theorems of Frauchiger and Renner, Brukner, Bong et. al.. Basing the ontology of the theory on relative facts clarifies the role of decoherence in bringing about the classical world and solves the apparent incompatibility between the `linear evolution' and `projection' postulates.

description: The recently discovered sharp peak in the K+/pi+ ratio is discussed in the framework of the statistical model. In this model a rapid change is expected as the hadronic gas undergoes a transition from a baryon-dominated to a meson-dominated gas. The transition happens at sqrt{s_{NN}} = 8.16 GeV, temperature T = 140 MeV and baryon chemical potential mu_B = 410 MeV. The maximum in the Lambda/pi ratio is well reproduced by the statistical model, but the change in the K+/pi+ ratio is much less pronounced than the one observed by the NA49 collaboration. Further experimental tests are proposed to clarify the nature of the transition. In particular, the maxima expected in the statistical model for the Xi/pi and Omega/pi ratios occur at slightly higher beam energies than the maxima for the Lambda/pi and K+/pi+ ratios.

Monte Carlo simulation of radiation transport in inhomogeneous phantoms irradiated using sterotactic radiosurgery beams
Creators: name: Cho, Jongmin
Publisher: name: University of British Columbia
Year: 2009

description: 6 MV stereotactic beams, with collimators of size 25 mm and 40 mm, were used to irradiate many homogeneous phantoms of different densities to quantitatively study charged particle disequilibrium. In each phantom, the magnitudes of the collisional KERMA and dose were compared. When the collisional KERMA has almost the same magnitude as dose, lateral charged particle equilibrium is relatively well established, which is the case for homogeneous water, aluminum and bone phantoms. However, when the collisional KERMA has significantly higher magnitude than the dose, there is serious charged particle disequilibrium, which is the case for homogeneous balsa and cedar phantoms. The same beams were used to irradiate many composite phantoms to study the origins of over-dosage and under-dosage in inhomogeneities. In the composite phantoms that contain balsa and cedar wood slabs, a reduction of dose in balsa and cedar was observed. This dose reduction is attributed to the longer lateral range of electrons in low density materials and therefore rapid increase of lateral charged particle disequilibrium. In the composite phantom that contains a bone slab, there was no significant change of dose in the bone slab. This is because there is no change of lateral charged particle equilibrium from polystyrene slabs to the bone slab. These observations have immediate relevance to small beam Stereotactic Radiosurgery in the head and neck region since this region has high density (bones) and low density (air cavities) material between water equivalent tissue.

description: In the first part of the present work, relevant findings concerning the laccase (Lacc) activation of alkyl gallates, and its implementation in developing hydrophobic properties on cellulose-based substrates are reported. Surface state energy by water contact angle (CA), absorption tests, and Cobb60 measurements were used to assess the hydrophobic behavior of treated substrates. SEM images of paper samples treated with functionalization solutions (FS) revealed the presence of lauryl gallate (LG, dodecyl 3,4,5,-trihydroxybenzoate) particles attached to fiber surfaces. Secondly, the chemical structure of the enzyme-oxidized LG and several gallates of variable chain length was elucidated by using Fourier transform infrared (FTIR) spectroscopy, and a plausible oxidation mechanism was developed. Based on them, the hydrocarbon chain of LG remains unaltered after enzyme oxidation, while the aromatic ring is significantly altered to form acidic adducts undergoing strong hydrogen bonding. Possible routes for the grafting of enzyme-modified LG to cellulose are proposed.

description: We consider effects of the spin degree of freedom on the nanomechanics of a single-electron transistor (SET) containing a nanometer-sized metallic cluster suspended between two magnetic leads. It is shown that in such a nanoelectromechanical SET(NEM-SET) the onset of an electromechanical instability leading to cluster vibrations and "shuttle" transport of electrons between the leads can be controlled by an external magnetic field. Different stable regimes of this spintronic NEM-SET operation are analyzed. Two different scenarios for the onset of shuttle vibrations are found.

description: Migration patterns are changing from large metropolis to rural towns. Rather than temporary migration of male heads of households the patterns are now for families to migrate in various stages. Rural Missouri towns have attracted newcomers. Foreign born Hispanics in non metro Missouri have low income earnings, and education, mobility and being woman have a negative effect on income earnings, as regression results show. The livelihoods of rural newcomers are vulnerable, with low income, multiple adults working in the households and with limited English proficiency. This is consistent with the life stories of women in a small town near a meat processing plant in Missouri.

description: The prediction of the equation of state of hot, dense nuclear matter is one of the most complicated and interesting problems in nuclear astrophysics. At the same time, knowledge of it is the basic ingredient for some of the most interesting studies. In the present work, we concentrate our study on the construction of the equation of state of hot, dense nuclear matter, related mainly to the interior of the neutron star. We employ a theoretical nuclear model, which includes momentum-dependent interaction among the nucleons, along with the \textit{state-of-the-art} microscopic calculations. Thermal effects are introduced in a self-consistent way, and a set of isothermal and isentropic equations of state are predicted. The predicted equations of state are used in order to acquire and to extend the knowledge of the thermal effect on both nonrotating and rapidly rotating with the Kepler frequency neutron stars. The simultaneous study of thermal and rotation effects provides useful information on some of the most important quantities, including the mass (gravitational and baryon) and radius, the Kepler frequency and Kerr parameter, the moment of inertia, etc. These quantities are directly related to studies of protoneutron stars and mainly the hot and rapidly rotating remnant of a binary neutron star merger. Data from the late observations of binary neutron star mergers and the present study may offer useful tools for their investigation and help in providing possible constraints on the equation of state of nuclear matter.

description: This paper describes theoretical modelling of electrostatic lenses based on 3, 4 and 5 closely spaced cylindrical electrodes, respectively. In each case, modelling is carried out numerically using commercial packages SIMION and LENSYS, and a variety of performance parameters are obtained. These include the magnification, the 3rd order spherical and chromatic aberration coefficients. Special cases such as zoom lens (i.e., lenses whose magnification may be changed without losing focus) are considered. Results are obtained as a function of the ratios of the electrode lengths and gaps, and as a function of ratios of the controlling voltages. As a result, it is shown that how a multi-element lens system can be operated with the whole focal properties in a useful mode for using in experimental studies.

description: Kerr soliton microcombs have recently emerged as a prominent topic in integrated photonics and enabled new horizons for optical frequency metrology. Kerr soliton microcombs, as its name suggests, are based on the high-order cubic optical nonlinearity. It is desirable to exploit quadratic photonic materials, namely Pockels materials, for soliton generation and on-chip implementation of 1f-2f comb self-referencing. Such quadratically-driven solitons have been theoretically proposed, but have not yet been observed in a nanophotonic platform despite of recent progresses in quadratic comb generation in free-space and crystalline resonators. Here we report photonic chip-based Pockels microcomb solitons driven by three-wave mixing in an aluminum nitride microring resonator. In contrast to typical Kerr solitons, our Pockels soliton features unity soliton generation fidelity, two-by-two annihilation of multi-soliton states, favorable tuning dynamics, and high pump-to-soliton conversion efficiency.
