description: I start with a brief summary of Higgs Mechanism and supersymmetry. Then I discuss the theoretical constraints, current limits and search strategies for Higgs boson(s) at LHC - first in the SM and then in the MSSM. Finally, I discuss the analogous constraints and search strategies for the superparticles, concentrating on the minimal supergravity model. Recent advances in identifying the most promising channels for Higgs and SUSY searches are emphasized.

description: Using panel data of more than 1,000 rural households from three rural provinces in Vietnam, we find that farming efficiency is a driver of cropland rental market development that enhances land use efficiency and results in an overall income gain for market participants. Our findings highlight the importance of cropland rental markets in facilitating economic transformation in rural areas of rapidly growing economies, but also indicate the need to take care of the poor to ensure that they are not left behind.

description: The recreational craft industry in Europe was first regulated in 1998 in the Recreational Craft Directive (RCD) with the purpose to tighten legislation for engine exhaust emissions. However, still today, mainly diesel engines are used for propulsion (as alternative or complementing propulsion from sails) and for charging batteries onblue water Sailing Yachts (charter and owner yachts at Sea) which lead to exhaustemissions. The purpose of this thesis was to assess the current average usage and dimensioning of solar applications onboard of Sailing Yachts (SY) in the Mediterranean Sea. The core question was to find out to which extent photovoltaic (PV) applications allow for a reduction of the usage of the diesel engine and consequently for a decrease of CO2 emissions.Based on literature research and a proprietary survey conducted among 47 SY owners with PV installation in the Mediterranean Sea, it was found that the average SY has a size of 12 – 14m and a weight of 10 -13 tons. A “traditional” average SYwithout any RE installation onboard, being at Sea 100-140 days per year, 8 hours aday, with 45% of engine time (3,6 hours per day) may consume between 500 – 1080l diesel per year. With an output of 2,66 kg CO2 per liter of marine diesel used, yearlyCO2 emissions may be in a range from 1,3 tons up to 2,9 tons CO2.Based on the average daily solar output in the Mediterranean Sea, which was calculated with an average of 3,82 Wh for 1W horizontally c-Si, and an average installation size of 1,77 m2, the average capacity of a PV application onboard a SY results to be 286 Wp. The average daily output for 286 Wp would be 1.086 Wh (1,09kWh). Comparing this final energy yield with the calculated average daily energy demand of 207 Ah (resulting in 2.484 Wh @ 12V), a larger than average dimensioning to cover the energy demand at least from March until October is needed.It was found that diesel consumption and diesel savings resulting from a PV installation onboard depend greatly not only on dimensioning of the system in terms of - engine, battery, PV panels, battery charger etc. – but also on the behavior of the SY owner/charterer respectively the crew. The total amount of energy consumed onboard and the resulting need of recharging batteries, will be as important as the willingness to sail more and use the engine only if necessary. The result of the proprietary survey showed that some participants were able to save a lot of diesel while others indicated to have hardly any savings at all. The average percent age resulted in nearly 30% of possible diesel and consequently CO2 savings on a yearly basis by the installation of a PV application.

description: Acoustic reverberation is one of the most relevant factors that hampers the localization of a sound source inside a room. To date, several approaches have been proposed to deal with it, but have not always been evaluated under realistic conditions. This paper proposes exploiting spatial diversity as an alternative approach to achieve robustness against reverberation. The theoretical arguments supporting this approach are first presented and later confirmed by means of simulation results and real measurements. Simulations are run for reverberation times up to 2 s, thus providing results with a wider range of validity than in other previous research works. It is concluded that the use of systems consisting of several, sufficiently separated, small arrays leads to the best results in reverberant environments. Some recommendations are given regarding the choice of the array sizes, the separation among them, and the way to combine SRP-PHAT maps obtained from diverse arrays.

description: We study the behavior of the rho vector mass in the context of the almost baryon-free environment of an ultra-relativistic heavy-ion collision. We show that rho scattering within the hadronic phase of the collision leads to a temperature dependent, decrease of its intrinsic mass at rest, compared to the value in vacuum. The main contributions arise from s-channel scattering with pions through the formation of a1 resonances as well as with nucleons through the formation of even parity, spin 3/2 [N(1720)] and 5/2 [Delta(1905)] nucleon resonances. We show that it is possible to achieve a shift in the intrinsic rho^0 mass of order - 40 MeV, when including the contributions of all the relevant mesons and baryons that take part in the scattering, for temperatures between chemical and kinetic freeze-out.

University-Community Makerspaces : Best Practice Review for the UBC Stadium Neighbourhood Planning Through the Lens of Eight Case Studies
Creators: name: Huang, Emily
Publisher: name: The University of British Columbia
Year: 2019

description: Campus and Community Planning staff (C+CP) at the University of British Columbia (UBC) is undergoing a planning process for the university’s new residential community – Stadium Neighbourhood (SN). There is interest from staff and community members for a flexible/makerspace. As a response, staff is exploring to dedicate a portion of the academic and educational space in SN for a makerspace. There is currently a lack of case study precedents to guide this vision and describe what a self-sustaining makerspace could look like in SN. As a result, this research is guided by literature review, case studies, and semi-informal interviews. The goal of the future makerspace is to provide space primarily for area residents, but also be accessible to UBC students, faculty, and staff to exchange skills, knowledge, and establish an environment for community, learning, and innovation.

description: Stakeholders in agricultural land markets can have a legitimate interest in the impact of policy changes on land prices. Agricultural economists may be asked to answer questions regarding the potential impacts of suggested policy changes on land price, ex ante. This paper addresses the question of what agricultural economists can answer, given enquiries into such matters. Based on a comparison of methodologies used the paper concludes, that even though methods in the field are advanced they tend to focus on either a cash flow dimension or a quality dimension of land price, while the questions that stakeholders need answered require both.

description: Reconfigurable intelligent surface (RIS)-assisted communications appear as a promising candidate for future wireless systems due to its attractive advantages in terms of implementation cost and end-to-end system performance. In this paper, two new multiple-input multiple-output (MIMO) system designs using RISs are presented to enhance the performance and boost the spectral efficiency of state-of-the-art MIMO communication systems. Vertical Bell Labs layered space-time (VBLAST) and Alamouti's schemes have been considered in this study and RIS-based simple transceiver architectures are proposed. For the VBLAST-based new system, an RIS is used to enhance the performance of the nulling and canceling-based sub-optimal detection procedure as well as to noticeably boost the spectral efficiency by conveying extra bits through the adjustment of the phases of the RIS elements. In addition, RIS elements have been utilized in order to redesign Alamouti's scheme with a single radio frequency (RF) signal generator at the transmitter side and to enhance its bit error rate (BER) performance. Monte Carlo simulations are provided to show the effectiveness of our system designs and it has been shown that they outperform the reference schemes in terms of BER performance and spectral efficiency.

The Origins of X-ray Line Emissions in Circinus~X-1 at Very Low X-ray Flux

description: Accretion conditions and morphologies of X-ray transients containing neutron stars are still poorly understood. Circinus X-1 is an enigmatic case where we observe X-ray flux changes covering four orders of magnitude. We observed Circinus X-1 several times at its very lowest X-ray flux using the high energy transmission grating spectrometer on board the Chandra X-ray Observatory. At a flux of 1.8$\times10^{-11}$ \ergcm we observed a single 1.6 keV blackbody spectrum. The observed continuum luminosity of 10$^{35}$ \ergsec is about two orders of magnitude too low to explain the observed photoionized luminosity suggesting a much more complex structure of the X-ray source which is partially or entirely obscured as had been previously suggested. This affects most emissions from the accretion disk including previously observed accretion disk coronal line emissions. Instead, the strongest observed photoionized lines are blueshifted by about $\sim 400$ \kms\ and we suggest that they originate in the ionized wind of a B5Ia supergaint companion supporting a previous identification. The neutron star in Cir X-1 is very young and should have a high magnetic field. At the observed luminosity the emission radius of the blackbody is small enough to be associated with the accretion hot spot as the X-ray emitting region. The small emission radius then points to a field strength below $10^{12}$ G which would be consistent with the observation of occasional type I X-ray bursts at high magnetic fields. We discuss Cir X-1 in the context of being a high-mass X-ray binary with some emphasis on a possible Be-star X-ray binary nature.

title: An Object-Oriented System for Engineering Polymer Information
Creators: name: Spedding, Vanessa
Publisher: name: The Open University
Year: 1995

description: Issues arising from the development of a computer-based information system for engineering polymer data have been explored.

 The system was designed with the aim of providing a user-independent representation of engineering polymers that would organise the data pertaining to them and be amenable to extension and evolution to allow for new materials and new properties.

 A classification of engineering polymer materials was developed to provide the structure for the representation, and an existing computer information system was modified in order to accommodate it. The classification was designed to create and order classes of similar materials to enable easy access to their information. Criteria for grouping material grades into families and families into a hierarchy were assessed. Existing polymer classifications were analysed; several alternative approaches to the factoring process are described.

 The final taxonomy was implemented within the object-oriented information system POISE, written in the language Smalltalk 80TM. Inherent in the system is a facility to support browsing of general class information. Other tools developed during the course of the project allow the addition and positioning of new classes, grades, properties and data and searching for grades by property value or name.

 It was shown that a classification based on criteria of similar chemical structure is a prerequisite for extensibility. Also demonstrated was that no such classification will consistently group together grades that are similar in respect of all of their physical and engineering property data for the uses of engineering designers.

 A detailed analysis of the properties used to describe grades of engineering polymer gave an insight into the above dichotomy. To accommodate the resulting conflict, the polymer information system was enhanced to incorporate an orthogonal factoring at the grade level in addition to that already created by the final classification based on chemical families.

description: We investigate factors which may drive the number of agents who compete for a specific piece of agricultural land by fitting count data models on data originating from a local committee, the CDOA, which is responsible for agricultural guidance of the prefect in delivering the necessary ‘authorizations to farm’. We notably find that the size of the offered land positively contributes to the competitor number, and that new entrants face less competition. The seemingly counterintuitive result that a locally denser farmer population yields fewer competitors is given a line of potential explanation pertaining to the likely role of farmer unions.

description: The properties of molecules and materials containing light nuclei are affected by their quantum mechanical nature. Modelling these quantum nuclear effects accurately requires computationally demanding path integral techniques. Considerable success has been achieved in reducing the cost of such simulations by using generalized Langevin dynamics to induce frequency-dependent fluctuations. Path integral generalized Langevin equation methods, however, have this far been limited to the study of static, thermodynamic properties due to the large perturbation to the system's dynamics induced by the aggressive thermostatting. Here we introduce a post-processing scheme, based on analytical estimates of the dynamical perturbation induced by the generalized Langevin dynamics, that makes it possible to recover meaningful time correlation properties from a thermostatted trajectory. We show that this approach yields spectroscopic observables for model and realistic systems which have an accuracy comparable to much more demanding approximate quantum dynamics techniques based on full path integral simulations.

description: In this paper, we apply the dynamic Gordon growth model to Western Germany and decompose the rent-price ratio into the expected present values of rental growth rates, real interest rates, and a land premium, i.e., the excess return on investment. This analysis reveals that the recent price surge on agricultural land markets was not unprecedented; that the land market rent-price ratio is rather low compared to other markets and varies considerably among federal states; and that (expected) premia for land are mostly negative, rendering investments in farmland unprofitable for financial investors. Finally, we find that changing expected present values of returns on land investments are the major driver for land price volatility.

description: Agricultural and forestry land markets are regulated in several European countries. However, assessing the economic consequences of land market regulation for agricultural and forestry firms is methodologically challenging for various reasons. The aim of this study is to highlight the usefulness of exploring expert stakeholders’ mental models in order to gain insights into the economic impacts of agricultural and forestry land market regulation. We use thematic analysis based on in-depth interview data to explore Swedish expert stakeholders’ mental models about the regulation of the Swedish agricultural and forestry land market. Findings point to that the current regulation does not have any major impacts on the economic situation of agricultural and forestry firms in Sweden.

Working in a rather general framework, we provide a "gap condition" which is sufficient to conclude existence of type-I BEC in probability and in the $r$th mean. We illustrate our results in the context of the well-known (one-dimensional) Luttinger-Sy model. Here, whenever the particle density exceeds a critical value, we show in addition that only the ground state is macroscopically occupied.

description: Land markets all over the world are diversely regulated, although a vast stock of empirical literature seems to suggest that unrestricted land market is the best policy design option. Since diversity of regulations proves this unlikely, it is surprising that little attention is paid in academic literature to theory that would allow to choose land market design based on welfare implications of various restrictions. In this paper, we build upon the framework described in the literature and develop a theoretical model that enables to infer an optimal choice of (maximum land holdings) restrictions in the presence of land market imperfections.

description: Cold dark matter model predicts that the large-scale structure grows hierarchically. Small dark matter halos form first. Then, they grow gradually via continuous merger and accretion. These halos host the majority of baryonic matter in the Universe in the form of hot gas and cold stellar phase. Determining how baryons are partitioned into these phases requires detailed modeling of galaxy formation and their assembly history. It is speculated that formation time of the same mass halos might be correlated with their baryonic content. To evaluate this hypothesis, we employ halos of mass above $10^{14}\,M_{\odot}$ realized by TNG300 solution of the IllustrisTNG project. Formation time is not directly observable. Hence, we rely on the magnitude gap between the brightest and the fourth brightest halo galaxy member, which is shown that traces formation time of the host halo. We compute the conditional statistics of the stellar and gas content of halos conditioned on their total mass and magnitude gap. We find a strong correlation between magnitude gap and gas mass, BCG stellar mass, and satellite galaxies stellar mass, but not the total stellar mass of halo. Conditioning on the magnitude gap can reduce the scatter about halo property--halo mass relation and has a significant impact on the conditional covariance. Reduction in the scatter can be as significant as 30%, which implies more accurate halo mass prediction. Incorporating the magnitude gap has a potential to improve cosmological constraints using halo abundance and allows us to gain insight into the baryon evolution within these systems.

description: The agricultural sector in Finland has witnessed a rapid structural change since the Finnish EU-accession. At the same time, agricultural land prices have increased considerably. Using a hedonic pricing model, we investigated the characteristics affecting the prices of parcels sold. We analysed a dataset consisting of over a thousand additional agricultural land transactions and discovered several regional and production related characteristics affecting prices. The generalised additive modelling framework enabled estimation of a regional price level as a smooth trend surface. The model captured spatial dependency in the prices while retaining the sensible interpretation of the results.
Hydrodynamic electron transport near charge neutrality

description: We develop the theory of hydrodynamic electron transport in a long-range disorder potential for conductors in which the underlying electron liquid lacks Galilean invariance. For weak disorder, we express the transport coefficients of the system in terms of the intrinsic kinetic coefficients of the electron liquid and the correlation function of the disorder potential. We apply these results to analyze the doping and temperature dependence of transport coefficients of graphene devices. We show that at charge neutrality, long-range disorder increases the conductivity of the system above the intrinsic value. The enhancement arises from the predominantly vortical hydrodynamic flow caused by local deviations from charge neutrality. Its magnitude is inversely proportional to the shear viscosity of the electron liquid and scales as the square of the disorder correlation radius. This is qualitatively different from the situation away from charge neutrality. In that case, the flow is predominantly potential, and produces negative viscous contributions to the conductivity, which are proportional to the sum of shear and bulk viscosities, and inversely proportional to the square of disorder correlation radius.

Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

Type genus: Haplotaxis Hoffmeister, 1843
(with type species Lumbricus gordioides Hartmann in Oken, 1819);
Phreoryctes Hoffmeister, 1845 is a junior synonym to Haplotaxis.
Diagnosis [modified from the Haplotaxis description in Brinkhurst (1988)]
Body form narrow and elongate, body wall with well-developed cuticular layer, brain anterior to mouth within elongate peristomium, the latter usually biannulate with a distinct transverse groove, although not in all species (Brinkhurst and Marchese 1987, Brinkhurst and McKey-Fender 1991) (Figs 2A–C, 3C). Ventral chaetae large, single, usually straight in basal part and curved to strongly hooked distally (Fig. 3I–J); simple-pointed, but may have distal ornamentation or keel; modified genital chaetae in at least two species. Dorsal chaetae smaller than ventrals, single, sigmoid to nearly straight; may be absent in many or all segments. Foregut without a dorsal, pharyngeal pad; mouth opens into a capacious, thin-walled oral cavity (possibly eversible) (Fig. 3B–C); mouth and oral cavity with strongly developed radial muscle bands extending to the body wall, interspersed with diagonal muscle bands (Figs 2A–C, 3A); conspicuous pharyngeal glands absent. Oral cavity terminates in a thick-walled, muscular pharynx (or ‘gizzard’, a disputed term here—see ‘Gizzard vs. muscular pharynx in Haplotaxis ’ in the discussion), consisting of transverse-circular muscle bands, interspersed with radial muscle, usually in IV– V (Fig. 3B–D). Nephridia present in all middle and posterior segments; ducts with large, irregular cells, forming a compact mass filling much of the segment (Fig. 3G). Conspicuous coelomocytes absent. Dorsal and ventral blood vessels connected by simple commissural vessels, often in each segment; those in anterior segments long and convoluted. Small clusters of glandular cells (‘Timm’s glands’) may be present midventrally in some segments, approaching or surrounding the ventral nerve cord (Fig. 3H). Clitellum one cell thick. Spermathecae in 2–4 segments, in front of gonadal segments, typically petiolate, with pores anterior and lateral or dorsolateral. Usually with two pairs of testes (typically in X– XI), followed by one or two pairs of ovaries with the second pair rather than the first being lost where reduction has occurred; eggs mesolecithal. Gonoducts simple, without attached prostate glands, but there may be glands around the pores; male ducts tubular, plesioporous.

description: Land consolidation has been viewed by policy makers as panacea for tackling the inherited challenges of Albania´s egalitarian land reform. The paper argues that farmers´ efforts towards farm consolidation through land purchase and rent-in are affected by overall structural factors. Farm structure, farm-orientation and other socio-economic factors play an important role in farmers´ decision to purchase and rent-in agricultural land. Rental market has been the most common mechanism for consolidation, although agriculture land rent is not suitable for all agriculture activities, such as those which require long term investments.
title: Evaluating the viability and required market conditions for integrating renewable energy into the oil refining process via hydrogen

description: Following a raft of commitments made by major oil companies over the last 12 months to reach net-zero emissions targets, this paper will examine the viability of integrating renewable energy into the oil refining process through the replacement of a fossil fuel-based system for producing hydrogen with an electrolyser using renewable electricity. Hydrogen is an important chemical input in the refining process for road fuels and other oil products whose current production is overwhelmingly natural gas-based and, as such, makes asignificant contribution to oil companies’ emissions.The topic is analysed first by establishing a realistic basis for cost comparison, as well as key assumptions regarding technology-specific performance characteristics, between the incumbent technology for hydrogen production and the renewable replacement route. From this point the analysis branches out into various scenarios, where the key price input sinfluencing the economic viability of the replacement are allowed to diverge in a range of different ways. For some scenarios, financial support mechanisms of different kinds are assumed.The viability of investing, as well as the cost of producing hydrogen, is assessed for each of these scenarios. Further points of comparison regarding investment viability and hydrogen production costs are also established by assuming price variables for some scenarios which correspond not to the main focus market (Europe), but instead to regions with superior priceconditions for long-term renewable electricity supply contracts (the US and the Middle East).The results of the analysis indicate that even favourable market price developments over the coming years struggle to yield any kind of viable investment in an electrolyser as are placement for the incumbent technology. A consistent additional revenue stream in theform of a subsidy is required to achieve a viable investment case, given the inherent disadvantage for the replacement technology vs. the pre-existing system. Despite the relative difficulty in achieving a positive investment case, a number of the assessed scenarios do suggest low achievable levels for renewable hydrogen production costs, which may be improved further in the future. These should present a compelling alternative to fossil fuel based production routes for new hydrogen production capacity in locations with the requisite pricing constellation.
When Less is More: Historical Yield Data and Rating Area Crop Insurance Products

description: The Federal Crop Insurance Program -- operated by the United States Department of Agriculture's Risk Management Agency (RMA) -- offers various types of insurance, covers a multitude of crops, carries significant liability, and is the cornerstone of domestic farm policy. Currently, RMA uses county yield data from the 1950s onwards to set guarantees and estimate premium rates for their area yield and revenue insurance products but trims yield data prior to 1991 in rating their newer shallow loss products. The past 70 years reflect very significant innovations in both seed and farm management technologies; innovations that have likely moved mass all around the support of the yield distribution. Although the RMA rating methodology corrects for time-varying movements in the first two moments, it is unclear whether using the entire yield series remains appropriate. We use distributional tests and an out-of-sample retain-cede rating game to answer if RMA should or should not historically trim yields in estimating their premium rates. Despite small sample sizes and the need to estimate tail probabilities, the historical data appears to be sufficiently different such that trimming is justified. While we caution against extrapolation of our results, they do give cause for consideration in other empirical analyses using historical yield data.

description: Exact solutions, in terms of special functions, of all wave equations $% u_{xx} - u_{tt} = V(x) u(t,x)$, characterised by eight inequivalent time independent potentials and by variable separation, have been found. The real valueness of the solutions from computer algebra programs is not always manifest and in this work we provide ready to use solutions. We discussed especially the potential $\cosh^{-2}x (m_1 + m_2 \sinh x)$. Such potential approximates the Schwarzschild black hole potential for even parity.

New light on the S235A-B star forming region

description: The S235A-B star forming region has been extensively observed in the past from the radio to the near-IR, but what was happening in the immediate surroundings of the water maser, placed in between the two nebulosities, was still unclear because of insufficient resolution especially in the spectral range from the Far-IR to the mm, even though there were sound indications that new young stellar objects (YSOs) are being formed there. We present here new high resolution maps at mm wavelengths in different molecules (HCO+, C34S, H2CS, SO2 and CH3CN), as well as in the 1.2 and 3.3 mm continuum obtained with the Plateau de Bure interferometer, and JCMT observations at 450 micron and 850 micron that unambiguously reveal the presence of new YSOs placed in between the two HII regions S235A and S235B and associated with the water maser. A molecular core and an unresolved source in the mm and in the sub-mm are centred on the maser, with indication of mass infall onto the core. Two molecular bipolar outflows and a jet originate from the same position. Weak evidence is found for a molecular rotating disk perpendicular to the direction of the main bipolar outflow. The derived parameters indicate that one of the YSOs is an intermediate luminosity object (L~1000 Lsun) in a very early evolutionary phase, embedded in a molecular core of ~100 Msun, with a temperature of 30 K. The main source of energy for the YSO could come from gravitational infall, thus making of this YSO a rare example of intermediate luminosity protostar representing a link between the earliest evolutionary phases of massive stars and low mass protostars of class 0-I.

description: The aim of this dissertation is to present and index the contents of the post-war magazine Το Περιοδικό μας which was released during the period July 1958 - June 1960. To begin with, the targets and the aspirations of the publication will be shown as they emerge from the published texts of its editorial team. Then the collaborators of the magazine are presented based on the position they held in the world of literature at that time and the frequency of their authorial presence in the magazine. Subsequently the literary texts published by the magazine are presented. Following from there, there are the critics and the theatrical reviews that held a constant position in each issue and in a separate section comments on various studies (reviews, chronicles, memories etc.) are published in the magazine. Finally, the paper includes two indices. The first lists the contents of the magazine in issues and the second the contributors of the magazine in alphabetical order.

Type genus: Ohtakiana Fend & Torii gen. nov.
Diagnosis As for type genus.
Remarks
This family is currently monotypic, and morphologically distinguished only by the characters listed below in the genus diagnosis and species description. Morphologically, it resembles members of the Pelodrilidae, particularly Hologynus, and more detailed anatomical study is needed for comparison. At this point, the best distinguishing character appears to be the large midventral glands.
