description: Massive young stellar objects (MYSO) are surrounded by massive dusty envelopes. Our aim is to establish their density structure on scales of ~1000 AU, i.e. a factor 10 increase in angular resolution compared to similar studies performed in the (sub)mm. We have obtained diffraction-limited (0.6") 24.5 micron images of 14 well-known massive star formation regions with Subaru/COMICS. The images reveal the presence of discrete MYSO sources which are resolved on arcsecond scales. For many sources, radiative transfer models are capable of satisfactorily reproducing the observations. They are described by density powerlaw distributions (n(r) ~ r^(-p)) with p = 1.0 +/-0.25. Such distributions are shallower than those found on larger scales probed with single-dish (sub)mm studies. Other sources have density laws that are shallower/steeper than p = 1.0 and there is evidence that these MYSOs are viewed near edge-on or near face-on, respectively. The images also reveal a diffuse component tracing somewhat larger scale structures, particularly visible in the regions S140, AFGL 2136, IRAS 20126+4104, Mon R2, and Cep A. We thus find a flattening of the MYSO envelope density law going from ~10 000 AU down to scales of ~1000 AU. We propose that this may be evidence of rotational support of the envelope (abridged).

description: Initial-switching refers to the way in which the decay of an initially confined state begins, as the barrier isolating it from the exterior is relaxed. We study these effects in the context of Longhi's version of the Fano-Anderson model. Most authors assume the sudden approximation where the coupling is turned on instantaneously. We consider a finite rise time T, both numerically and analytically. When the coupling is ramped up linearly over a switching time T, we show that the asymptotic survival amplitude acquires a phase T and is modulated by a factor (sin T)/T. Several other results relating to the solution of the model are obtained. All site amplitudes have the same decay constant during the exponential decay regime. In the asymptotic regime, the amplitude and phase of decay oscillations depend on the initial-switching profile, but the period does not.

The administration of justice in the greater Vancouver area : the female offender
Creators: name: Sien, Mabel Aileen
Publisher: name: University of British Columbia
Year: 2011

description: There has been a great deal of concern regarding the extent of criminal behaviour and the effect of criminal behaviour on the criminal and on society generally. There is the general assumption that there are many differences between the female offender and the male offender. At the same time the law and the administration of justice are said to apply equally to both sexes. The dilemma Is partially resolved by an individual approach pursued by the personnel of the various institutions involved—the police officers, the magistrates or judges, the prosecutor, the probation officer, the prison matrons, the parole supervisor and all the people who come in contact with the woman from the time of arrest until the time of release. Many problems remain unsolved. The account of the process confronting the female offender is presented as objectively as possible based on information obtained mainly from interviews with representatives from the various institutions with whom the offender comes in contact; and, also from their records, from annual reports, brochures, Municipal by-laws, Federal and Provincial Statutes and the Criminal Code of Canada. It is an official account as compared to an unofficial account obtained from interviews with the women who are charged with various criminal offences. Statistics, while approximate figures, provide an estimate of the number of women charged with criminal offences and the types of crime in which they are frequently involved. The offences are by law indictable or summary offences, or can be either. Arrests can be made by certain persons under specified conditions. Bail may be granted or refused. The person who has been arrested may be locked in the City Gaol. There are various sentences permitted by law to be administered by the courts. The female offender may receive a suspended sentence. She may be placed on probation. She may be sent to prison at Oakalla or Kingston Penitentiary. Parole may be granted or refused. She obtains a criminal record. A combined individual-group approach to treatment might be more beneficial and have more lasting results than a primarily Individual approach or primarily a group approach. Successful rehabilitation may depend more on a well-informed public than on a sympathetic public made up of people who are willing to "take a chance" on hiring her or renting a room to her. An integrated team applying the problem-solving approach might result in a lower recidivist rate if any or all of the members of the team were made available to the offender when she first becomes arrested and is charged with a criminal offence. The distance must be lessened between the cultural expectations of the individual and the individual's ability to meet those expectations in socially acceptable ways.

description: We study the effects of the long-range disorder potential and warping on the conductivity and mobility of graphene ribbons using the Landauer formalism and the tight-binding p-orbital Hamiltonian. We demonstrate that as the length of the structure increases the system undergoes a transition from the ballistic to the diffusive regime. This is reflected in the calculated electron density dependencies of the conductivity and the mobility. In particular, we show that the mobility of graphene ribbons varies as mu(n) n^(-lambda), with 0

description: The edge-on starburst galaxy M82 exhibits complicated distributions of gaseous materials in its halo, which include ionized superwinds driven by nuclear starbursts, neutral materials entrained by the superwinds, and large-scale neutral streamers probably caused by a past tidal interaction with M81. We investigate detailed distributions of dust grains and polycyclic aromatic hydrocarbons (PAHs) around M82 to understand their interplay with the gaseous components. We performed mid- (MIR) and far-infrared (FIR) observations of M82 with the Infrared Camera and Far-Infrared Surveyor on board AKARI. We obtain new MIR and FIR images of M82, which reveal both faint extended emission in the halo and very bright emission in the center with signal dynamic ranges as large as five and three orders of magnitude for the MIR and FIR, respectively. We detect MIR and FIR emission in the regions far away from the disk of the galaxy, reflecting the presence of dust and PAHs in the halo of M82. We find that the dust and PAHs are contained in both ionized and neutral gas components, implying that they have been expelled into the halo of M82 by both starbursts and galaxy interaction. In particular, we obtain a tight correlation between the PAH and H$α$ emission, which provides evidence that the PAHs are well mixed in the ionized superwind gas and outflowing from the disk.

Sky maps without anisotropies in the cosmic microwave background are a better fit to WMAP's uncalibrated time ordered data than the official sky maps

description: The purpose of this reanalysis of the WMAP uncalibrated time ordered data (TOD) was two fold. The first was to reassess the reliability of the detection of the anisotropies in the official WMAP sky maps of the cosmic microwave background (CMB). The second was to assess the performance of a proposed criterion in avoiding systematic error in detecting a signal of interest. The criterion was implemented by testing the null hypothesis that the uncalibrated TOD was consistent with no anisotropies when WMAP's hourly calibration parameters were allowed to vary. It was shown independently for all 20 WMAP channels that sky maps with no anisotropies were a better fit to the TOD than those from the official analysis. The recently launched Planck satellite should help sort out this perplexing result.

description: Objective: To characterize the harvest and postharvest of the cocoa management system at La Chontalpa, Tabasco, Mexico. Design / methodology / approach: The study took place in the towns of Francisco Trujillo Gurría and Ernesto Aguirre Colorado de Huimanguillo, Tabasco, Mexico. The study was descriptive and accounted for 51 producers and those responsible for the cocoa profit centers. Producers were chosen through targetedsampling. A survey on their harvest and postharvest was applied, in addition to direct assessment in plantations and profit centers. Results: The cocoa harvesting is manual. The producers cut the ripe and almost ripe fruits, do not store and 58.8% of them do not break the fruit. With a “machete” cut the fruit in half and manually extract the grains. The fresh grains are sold at a profit. The cocoa is then fermented in wooden boxes, dried artificially, natural, or in a combined way, and packed in “yute” bags for sale. Profit centers do not keep track of their grain origin and make no selection or determine product quality. Study limitations / implications: All producers harvest in the same way, but the processes during post-harvest could differ at different collection centers. Findings / conclusions: The harvest of cocoa fruits at different maturity and the lack of storage causes a heterogeneous fermentation. The humidity level during the drying process is empirically determined.

description: The phrase “creative placemaking” is described by the American Planning Association as a set of different but related practices that engage “community members, artists, arts and culture organizations, community developers, and other stakeholders use arts and cultural strategies to implement community-led change.” Most often, creative placemaking strategies are generated by arts practitioners and struggle to find funding and partners in local government. This places Prince George’s County Park and Planning in a unique position: if it chooses to use creative placemaking, the burden of finding resources is somewhat more easily achievable, though it will need to find and engage community members and arts practitioners. The agency can help to scale-up projects that are already underway.

description: We investigate the black hole thermodynamics in a "deformed" relativity framework where the energy-momentum dispersion law is Lorentz-violating and the Schwarzchild-like metric is momentum-dependent with a Planckian cut-off. We obtain net deviations of the basic thermodynamical quantities from the Hawking-Bekenstein predictions: actually, the black hole evaporation is expected to quit at a nonzero critical mass value (of the order of the Planck mass), leaving a zero temperature remnant, and avoiding a spacetime singularity. Quite surprisingly, the present semiclassical corrections to black hole temperature, entropy, and heat capacity turn out to be identical to the ones obtained within some quantum approaches.

description: The methodology of Bayesian Model Averaging (BMA) is applied for assessment of newborn brain maturity from sleep EEG. In theory this methodology provides the most accurate assessments of uncertainty in decisions. However, the existing BMA techniques have been shown providing biased assessments in the absence of some prior information enabling to explore model parameter space in details within a reasonable time. The lack in details leads to disproportional sampling from the posterior distribution. In case of the EEG assessment of brain maturity, BMA results can be biased because of the absence of information about EEG feature importance. In this paper we explore how the posterior information about EEG features can be used in order to reduce a negative impact of disproportional sampling on BMA performance. We use EEG data recorded from sleeping newborns to test the efficiency of the proposed BMA technique.

In the presence of a light pseudoscalar, the SM-like Higgs scalar can decay dominantly into a 4-tau final state. In the fully constrained NMSSM with mSUGRA-like soft SUSY breaking terms, the correct dark matter relic density is obtained for a singlino-like LSP which modifies considerably all sparticle decay chains.

A kinetic exchange model based on that framework is proposed and its distributional features have been studied by considering its moments. Next, we derive the moments of the CC model (Eur. Phys. J. B 17 (2000) 167) as well. Some precise solutions are obtained which conform with the solutions obtained earlier. Finally, an output market is introduced with global price determination in the model with some necessary modifications.

A comparison of distances travelled to urban night school centers
Creators: name: McKinnon, Donald Peter
Publisher: name: University of British Columbia
Year: 2011

description: The purpose of this study is to analyse the distances travelled to three urban night school centers in order to determine whether each serves separate areas or whether each serves larger, overlapping areas. The sample population consisted of 486 adults enrolled in twenty-two courses offered as part of the 1962-1963 program. Some of these selected courses were in subjects offered at all three centers; some courses were offered at two of the centers and the remainder were offered at only one center. It was thus possible to compare the centers while controlling for the number of centers offering the same subject matter. Distributions of distances travelled to each course and to each group of courses were prepared. The chi-square test of independence was used to compare the various distributions and the significance of the difference between mean distances travelled was used to provide additional comparisons. Maps were prepared illustrating the residences of participants and a correlation was made to determine the relationship between the distances travelled and the percentage of sessions attended by the participant. The results indicated that half of the 486 participants travelled less than 2.8 miles. More lived between one and two miles from the center they attended than in any other mile interval from the center. Only five percent of the participants travelled more than nine miles and less than one percent travelled more than fourteen miles. The statistical tests indicated that there was an association between the distance travelled and the center attended. It was found that when courses were offered at one center only, there was no statistical difference between the patterns of distance travelled to the three centers. Participants seemed to travel from throughout the city of Vancouver to attend, no matter which center offered the course. Women who attend courses designed for women only travel shorter distances than men who attend courses designed for men only. For courses offered at all three centers, adults travelled further to John Oliver Night School and to Technical Night School than to Kitsilano Night School. Travel distance does not inhibit the subsequent attendance of those who enroll. The opening of new night school centers during the past fifteen years was reviewed and it was found that a new center opened within two miles of a large well established center is unlikely to attract sufficient clientele to be economically successful.

description: According to string theory, string ball is a highly excited long string which decays to standard model particles at the Hagedorn temperature with thermal spectrum. If there are extra dimensions, the string scale can be $\sim$ TeV, and we should produce string balls at CERN LHC. In this paper we study top quark production from string balls at LHC and compare with the parton fusion results at NNLO using pQCD. We find significant top quark production from string balls at LHC which is comparable to standard model pQCD results. We also find that $\frac{dσ}{dp_T}$ of top quarks from string balls does not decrease significantly with increase in $p_T$, whereas it deceases sharply in case of standard model pQCD scenario. Hence, in the absence of black hole production at LHC, an enhancement in top quark cross section and its abnormal $p_T$ distribution can be a signature of TeV scale string physics at LHC. String theory is also studied at LHC via string Regge excitations in the weak coupling limit in model independent framework. Since massive quark production amplitude is not available in string Regge excitations scenario, we compute massless quark production in string Regge excitations scenario and make a clear comparison with that produced from string balls at LHC for a given luminosity.

description: Peatland is a globally important store of carbon. Peatland restoration efforts are being increasingly undertaken yet effective monitoring of landscape-scale restoration projects has been limited. A particular gap in our understanding is the length of time required before a site reaches the target state. To address this, a classification model based on remote sensing data was developed for a peatland restoration area on blanket bog in northern Scotland, UK, to evaluate whether post-restoration trajectories followed predictable trends over time. The model was trained against a chronosequence of sites within a 20 × 10 km study area that are being restored following drainage and intensive non-native afforestation. Two versions of the model were created to compare the accuracy obtainable from the suite of Sentinel-2 satellite data versus sub-metre resolution aerial imagery from GetMapping (RGB and IR). The Sentinel-2 based model greatly outperformed the aerial imagery-based model. Adding surface slope to the classification did not significantly improve the accuracy of prediction. Prediction of starting and target land covers was very robust, and both the most recent and oldest restoration sites were well predicted spatially. The main uncertainties in the model were within sites of intermediate restoration age, and sites which underwent additional treatments after the initial restoration. Using standard vegetation and wetness indices as indicators, it was possible to track the progression of areas that had been felled and rewetted towards the spectral signal of the control blanket bog locations. A further study examined the use of multiple years of satellite data (2015–2021) and including Sentinel-1 SAR imagery, and confirmed the findings obtained with only a single climatically average year, and furthermore examined the efficacy of different restoration methods. We observed consistent trends of restoration sites beginning to resemble the target hydrologically and ecologically functional blanket bog state after 10–20 years post intervention.

description: Recent observations by H.E.S.S. and MAGIC strongly suggest that the Universe is more transparent to very-high-energy gamma rays than previously thought. We show that this fact can be reconciled with standard blazar emission models provided that photon oscillations into a very light Axion-Like Particle occur in extragalactic magnetic fields. A quantitative estimate of this effect indeed explains the observed data and in particular the spectrum of blazar 3C279.

Endovascular Management of Vein of Galen Aneurysmal Malformations: A Retrospective Analysis over a 15-Year Period
Creators: name: Zeenat Qureshi Stroke Institutes
Publisher: name: Zenodo
Year: 2023

description: Objectives—This retrospective study was aimed at assessing our results of endovascular management invein of Galen aneurysmal malformation (VGAM).Materials and Methods—This is a retrospective study of 26 patients of VGAM who underwent endo‐vascular treatment between 1998 and 2012. All patients underwent trans-arterial embolization. Of 26patients, 23 were treated using n-butyl cyano acrylate (Glue), while 3 out of 26 patients were treated usingthe ethylene vinyl alcohol (EVOH) copolymer.Results—Ages of the treated patients ranged from 1 day to 18 years of age. Of the patients treated, 17were males and 9 were females. Around 15 of the VGAMs were of the mural variety and 11 were choroidalin nature. A good outcome was seen in 22/26 (85%) of the patients. Complications were seen in total in7/26 patients (26.92%) of which 3/26 (12%) has a fatal outcome.Conclusion—Endovascular embolization for VGAMs is highly efficacious and has helped create a popu‐lation of VGAM survivors in this condition, which until only a few decades ago caused high mortality andmorbidity
Nuclear electron capture rate in stellar interiors and the case of 7Be

description: Nuclear electron capture rate from continuum in an astrophysical plasma environment (like solar core) is calculated using a modified Debye-Huckel screening potential and the related non-Gaussian q-distribution of electron momenta. For q=1 the well-known Debye-Huckel results are recovered. The value of q can be derived from the fluctuation of number of particles and temperature inside the Debye sphere. For 7Be continuum electron capture in solar core, we find an increase of 7 -- 10 percent over the rate calculated with standard Debye-Huckel potential. The consequence of this results is a reduction of the same percentage of the SSM 8B solar neutrino flux, leaving unchanged the SSM 7Be flux.

description: The age-related decrease in female fertility occurs because of ovarian ageing, which is when the number of healthy ovarian follicles stored in the ovary declines as women get older. The factors that control the rate of age-associated follicle depletion is unknown. However, preliminary data from mouse models suggest that inflammation may be a causative factor in the ovarian ageing process. The goal of this thesis is to determine if inflammation contributes to ovarian ageing, with a focus on follicle number. In the long term, the information gained from this study will help us to develop new strategies to improve reproductive health for women in advanced reproductive age.

description: We analyse scattering of a heavy atom off a weakly bound molecule comprising an identical heavy and a light atom in the Born-Oppenheimer approximation. We focus on the situation where the heavy atoms are bosons, which was realized in several experiments. The elastic and inelastic cross sections for the atom-molecular scattering exhibit a series of resonances corresponding to three-body Efimov states. Resonances in elastic collisions are accessible experimentally through thermalization rates, and thus constitute an alternative way of observing Efimov states.

Descriptive sample survey of selected social characteristics of public assistance clients and their perceptions of urban renewal plans in the Scheme III area, Vancouver, and of their perceptions of the City Social Service Department, Vancouver.
Creators: name: Vickars, John Beverly
Publisher: name: University of British Columbia
Year: 2011

description: This inquiry has three aims. Firstly, the study attempted to delineate selected social characteristics of a sample of the public assistance clients served by the City Social Service Department, Vancouver. Secondly, the preferences of the client population were sought concerning the affect of urban renewal plans in the Scheme III area. Thirdly, the thesis attempted to describe, the client population's image of the City Social Service Department. A hypothetical construct concerning the social characteristics of public assistance clients was cast in the form of five hypotheses. The depth interview was utilized as the major tool including sections concerning all three aims. Hypotheses were constructed concerning the second and third aims. The findings indicate that the client groups' social characteristics do include a minority of alienated and low morale attitudes. An absolute- level of deprivation as a social factor was largely absent. The hypothetical construct, was rejected. The study indicates that the majority of the study population prefers private housing to public housing; but feels that government should offer both public and private housing alternatives to clients dispossessed by urban renewal plans. The image of the City Social Service Department is described as extraordinarily positive with two reservations. Firstly, the social assistance rates are inadequate. Secondly, the agency staff has insufficient time to adequately discharge their duties. The study's main conclusion is that further research is required to substantiate or reject, the impressions gained' from this exploratory sample survey. A wider range of intervening variables must be more closely defined and examined. This study's restricted range and depth did not permit more than tentative conclusions to be drawn concerning the relationship between variables.

description: Many viruses target the nucleolus, a structure that controls diverse aspects of cell biology. However, roles in infection remain poorly understood, particularly for viruses that replicate in the cytoplasm such as henipaviruses. This project investigated nucleolar targeting by henipavirus matrix (M) protein to reveal the first nucleolar function, whereby subversion of the nucleolar DNA damage response effects silencing of ribosomal RNA production. The data further indicate this relates to interaction of M protein with multiple nucleolar proteins, with targeting regulated by several mechanisms. This expands understanding of virus-nucleolar interactions, and may contribute to the development of antiviral approaches.
