description: Estimation of the economic value of irrigation water is complicated by a lack of data on the price or marginal cost of water. Through econometric estimation of an aggregate total value product function, this paper obtains marginal irrigation water value estimates for the Middle Atlantic region. Additionally, the impact of temperature and soil conditions on aggregate production within the region is estimated. Ridge regression and covariance analysis are employed to deal with problems of multicollinearity and simultaneous equation bias, respectively. Estimates indicate a substantial and growing return to irrigation within the region.

description: The male-dominated hegemony that surrounds the world of sports creates a significant burden to individuals who do not conform to the ideal of a gender binary system and don’t refer to themselves as cisgender or heterosexual. Paradoxically, while sport has historically been a renowned method to teach fairness, equality and moral behaviour, today, this ideal is highly contested due to the handling of transgender “issues” of sports governing bodies and the sports media. This study, which falls into the gender, sexuality and sports media domains, seeks to explore how transgender people might re-imagine sports reporting in order to create social change in the area of transgender discrimination. It thus aims to propose suggestions for sports journalists who are covering transgender stories in sport. For the effective assessment of the study, a qualitative and participatory action research (PAR) approach was enacted as a method for scientific enquiry. A total of three participants were interviewed. The interview data, which was rich with suggestions about how to report about transgender issues objectively and informatively, was then used to inform a fictive story about a transgender athlete. This story was sent back to the participants, who were given the opportunity to give comments on the story. The findings of this study established that re-imagining sports journalism to create social change primarily entails providing readers with objective information, while also using correct terminology, ‘up-to-date language’, as well as integrating a humanising approach as a sports journalist.

description: We use the adiabatic compression theory to build a physically well - motivated Milky Way mass model in agreement with the observational data. The visible mass of the Galaxy is distributed in a spheroidal bulge and a multi - components disc parametrized by three galactic parameters, the Sun distance to the galactic centre, R_0, the total bulge mass, M_{bulge}, and the local disc surface density, Σ_{\odot}. To model the dark matter component, we adiabatically compress a Navarro, Frenk and White (NFW) halo (with concentration $c$ and total mass M_{vir}) for fixed values of the spin parameter, λ, the fraction of the mass in baryons, $m_b$, and the thin disc contribution to total angular momentum, j_d. An iterative selection procedure is used to explore in very detail the wide space of parameters only selecting those combinations of {R_0, M_{bulge}, Σ_{\odot}, λ, m_b, j_b, c, M_{vir}} that give rise to a Milky Way model in agreement with the observational constraints. This analysis leads us to conclude that only models with R_0 = 8.5 kpc, $0.8 x 10^{10} M_{\odot} < M_{bulge} < 1.6 x 10^{10} M_{\odot}$ and $49 M_{\odot} pc^{-2} \le Σ_{\odot} \le 56 M_{\odot} pc^{-2}$ can be reconciled with the set of observational constraints. As regard the parameters entering the adiabatic compression, we find $0.03 \le λ\le 0.10$ and $0.04 \le m_b \le 0.10$, while the final estimates of the parameters describing the initial halo profile turn out to be $5 \stackrel{

description: We provide the first global model recovery results for the IRLS (iteratively reweighted least squares) heuristic for robust regression problems. IRLS is known to offer excellent performance, despite bad initializations and data corruption, for several parameter estimation problems. Existing analyses of IRLS frequently require careful initialization, thus offering only local convergence guarantees. We remedy this by proposing augmentations to the basic IRLS routine that not only offer guaranteed global recovery, but in practice also outperform state-of-the-art algorithms for robust regression. Our routines are more immune to hyperparameter misspecification in basic regression tasks, as well as applied tasks such as linear-armed bandit problems. Our theoretical analyses rely on a novel extension of the notions of strong convexity and smoothness to weighted strong convexity and smoothness, and establishing that sub-Gaussian designs offer bounded weighted condition numbers. These notions may be useful in analyzing other algorithms as well.

Role of dimensions in first passage of a diffusing particle under stochastic resetting and attractive bias

description: Recent studies in one dimension have revealed that the temporal advantage rendered by stochastic resetting to diffusing particles in attaining first passage, may be annulled by a sufficiently strong attractive potential. We extend the results to higher dimensions. For a diffusing particle in an attractive potential $V({R})=k {R}^n$, in general $d$ dimensions, we study the critical strength $k = k_c$ above which resetting becomes disadvantageous. The point of continuous transition may be exactly found even in cases where the problem with resetting is not solvable, provided the first two moments of the problem without resetting are known. We find the dimensionless critical strength $κ_{c,n}(k_c)$ exactly when $d/n$ and $2/n$ take positive integral values. Also for the limiting case of a box potential (representing $n \to \infty$), and the special case of a logarithmic potential $k \ln\big(\frac{R}{a}\big)$, we find the corresponding transition points $κ_{c,\infty}$ and $κ_{c,l}$ exactly for any dimension $d$. The asymptotic forms of the critical strengths at large dimensions $d$ are interesting. We show that for the power law potential, for any $n \in (0,\infty)$, the dimensionless critical strength $κ_{c,n} \sim d^{\frac{1}{n}}$ at large $d$. For the box potential, asymptotically, $κ_{c,\infty} \sim (1 - \ln(\frac{d}{2})/d)$, while for the logarithmic potential, $κ_{c,l} \sim d$.

description: In order to improve the already existing models that are used extensively in bio sciences and applied sciences research, a new class of Weighted Power function distribution (WPFD) has been proposed with its various properties and different modifications to be more applicable in real life. We have provided the mathematical derivations for the new distribution including moments, incomplete moments, conditional moments, inverse moments, mean residual function, vitality function, order statistics, mills ratio, information function, Shannon entropy, Bonferroni and Lorenz curves and quantile function. We have also characterized the WPFD, based on doubly truncated mean. The aim of the study is to increase the application of the Power function distribution. The main feature of the proposed distribution is that there is no induction of parameters as compare to the other generalization of the distributions, which are complexed having many parameters. We have used R programming to estimate the parameters of the new class of WPFD using Maximum Likelihood Method (MLM), Percentile Estimators (P.E) and their modified estimators. After analyzing the data, we conclude that the proposed model WPFD performs better in the data sets while compared to different competitor models.

An interface with a linear quadrupole ion guide for an electrospray-ion trap mass spectrometer system
Creators: name: Cha, Byungchul
Publisher: name: University of British Columbia
Year: 2009

description: A new interface for an electrospray-3D ion trap mass spectrometer system has been developed and characterized. The interface allows ion accumulation, resonant ejection and ion isolation through dipole excitation. Linear quadrupoles have an intrinsic ion storage capability that can improve the duty cycle of the combined system. Also, dipole excitation with high resolution is possible in a quadrupole field in contrast to other linear multipole fields. Thus, selective resonant ejection allows the interface to achieve precise mass selection of ions trapped in the linear quadrupoles. The resolution of resonant ejection (m/Am)FWHM was found to be up to 308 with the molecular ion o f reserpine. One useful way of utilizing the high resolution of resonant ejection is isolating ions by applying composite waveform excitation. A composite waveform is generated from a computer by superimposing a range of frequencies. Within a band of frequencies a notch is placed around the secular frequency of an analyte ion, so that the waveform can excite all the ions except the ion with the secular frequency matching the notch. Ion isolation is shown to improve the sensitivity and resolution of the ion trap dramatically compared to the electrospray-ion trap system without ion isolation. A demonstration with a P PG (polypropylene glycol) solution with a trace amount of reserpine proves that some trace analysis can benefit greatly by eliminating background ions and thus reducing space charge problems in the ion trap. Quadrupole resonances are an alternative to dipole excitation for excitation of ions in the quadrupole trapping field. Although both dipole and quadrupole resonance excitation share similar characteristics, quadrupole excitation has a unique resonant frequency scheme. This complicated excitation frequency scheme for higher order resonances (n > 1) was first investigated experimentally in this thesis work. The results show that the maximum mass resolution in quadrupole excitation was less than in dipole excitation. Many interesting aspects of quadrupole excitation remain to be further investigated.

description: We consider a hybrid system of matter and light as a sensing device and quantify the role of cooperative effects. The latter generically enhance the precision with which modifications of the effective light-matter coupling constant can be measured. In particular, considering a fundamental model of $N$ qubits coupled to a single electromagnetic mode, we show that the ultimate bound for the precision shows double-Heisenberg scaling: $Δθ\propto1/(Nn)$, with $N$ and $n$ being the number of qubits and photons, respectively. Moreover, even using classical states and measuring only one subsystem, a Heisenberg-times-shot-noise scaling, i.e. $1/(N\sqrt{n})$ or $1/(n\sqrt{N})$, is reached. As an application, we show that a Bose-Einstein condensate trapped in a double-well potential within an optical cavity can detect the gravitational acceleration $g$ with the relative precision of $Δg/g\simeq10^{-9}\text{Hz}^{-1/2}$. The analytical approach presented in this study takes into account the leakage of photons through the cavity mirrors, and allows to determine the sensitivity when $g$ is inferred via measurements on atoms or photons.

description: Electronic government (e-government) uses information and communication technologies to deliver public services to individuals and organisations effectively, efficiently and transparently. E-government is one of the most complex systems which needs to be distributed, secured and privacy-preserved, and the failure of these can be very costly both economically and socially. Most of the existing e-government systems such as websites and electronic identity management systems (eIDs) are centralized at duplicated servers and databases. A centralized management and validation system may suffer from a single point of failure and make the system a target to cyber attacks such as malware, denial of service attacks (DoS), and distributed denial of service attacks (DDoS). The blockchain technology enables the implementation of highly secure and privacy-preserving decentralized systems where transactions are not under the control of any third party organizations. Using the blockchain technology, exiting data and new data are stored in a sealed compartment of blocks (i.e., ledger) distributed across the network in a verifiable and immutable way. Information security and privacy are enhanced by the blockchain technology in which data are encrypted and distributed across the entire network. This paper proposes a framework of a decentralized e-government peer-to-peer (p2p) system using the blockchain technology, which can ensure both information security and privacy while simultaneously increasing the trust of the public sectors. In addition, a prototype of the proposed system is presented, with the support of a theoretical and qualitative analysis of the security and privacy implications of such system.

description: We present a generator of random networks where both the degree-dependent clustering coefficient and the degree distribution are tunable. Following the same philosophy as in the configuration model, the degree distribution and the clustering coefficient for each class of nodes of degree $k$ are fixed ad hoc and a priori. The algorithm generates corresponding topologies by applying first a closure of triangles and secondly the classical closure of remaining free stubs. The procedure unveils an universal relation among clustering and degree-degree correlations for all networks, where the level of assortativity establishes an upper limit to the level of clustering. Maximum assortativity ensures no restriction on the decay of the clustering coefficient whereas disassortativity sets a stronger constraint on its behavior. Correlation measures in real networks are seen to observe this structural bound.

description: Development and commercialization of technologies that utilize on-farm energy sources are beset by uncertainty. Producer gas, a technology that allows wood to be converted to a gaseous fuel which can power internal combustion engines, is evaluated for irrigation systems using simulation modeling and stochastic efficiency analysis. For many market conditions, producer gas stochastically dominates diesel fuel for powering a center pivot irrigation system in terms of lower cost. Commercial potential exists, but experience with pilot installations is required to further reduce uncertainty.

description: Hybrid MHD-gyrokinetic code simulations are used to investigate the dynamics of frequency sweeping reversed shear Alfvén eigenmode (RSAE) strongly driven by energetic particles (EPs) during plasma current ramp-up in a conventional tokamak configuration. A series of weakly reversed shear equilibria representing time slices of long timescale MHD equilibrium evolution is considered, where the self-consistent RSAE-EP resonant interactions on the short timescale are analyzed in detail. Both linear and nonlinear RSAE dynamics are shown to be subject to the non-perturbative effect of EPs by maximizing wave-EP power transfer. In linear stage, EPs induce evident mode structure and frequency shifts; meanwhile, RSAE saturates by radial decoupling with resonant EPs due to weak magnetic shear, and gives rise to global EP convective transport and non-adiabatic frequency chirping. The spatiotemporal scales of phase space wave-EP interactions are characterized by the perpendicular wavelength and wave-particle trapping time. The simulations provide insights into general as well as specific features of RSAE spectra and EP transport from experimental observations, and illustrate the fundamental physics of wave-EP resonant interaction with the interplay of magnetic geometry, plasma non-uniformity and non-perturbative EPs.

The combined effects of applied electric fields and spontaneous electric polarization are considered for a system that consists of a Mn δ-doped well, a barrier, and a p-type ferroelectric well. We calculate the change in the envelope functions of carriers at the lowest energy sub-band, resulting from applied electric fields and switching the dipole polarization. By reversing the depolarizing field, we can achieve two different ferromagnetic transition temperatures of the ferromagnetic quantum well in a fixed applied electric field. The Curie temperature strongly depends on the position of the Mn δ-doped layer and the polarization strength of the ferroelectric well.

description: Net present value analysis is used to derive the marginal bid price for a beef herd sire from after-tax net revenues and cash flow influenced by genetic improvements. Marginal bid price represents the additional amount a producer could pay, above the present value of the current beef herd sire, for a sire expected to exhibit superior performance as reflected by increased average weaning weights of offspring. An analysis of the profitability of purchasing a breeding bull for a commercial beef cow herd is presented as an application. Several alternative scenarios illustrate the impact of selected determinants on the marginal bid price of a bull.

description: The syntheses of three structurally related substances, (±)-5-deoxovariecolin (204), (±)-5-deoxyvariecolol (93) and (±)-5-deoxyvariecolactone (226) are described as part of a general synthetic strategy toward the variecolin class of sesterterpenoids (48-52). Thus, the known Grignard reagent 99 was combined with 3-methylcyclohex-2-en-l-one (95) in a two step cyclopentene annulation sequence to provide 98. Conjugate addition of cuprate 107 to the enone 98 followed by an epimerization step provided ketone 44 with the correct relative configuration set at three stereogenic centers. Application of a novel cycloheptenone annulation protocol employing the bifunctional reagent 53 furnished the tricyclic intermediate 59. A sequence consisting of dissolving metal reduction and a 1,2-carbonyl transposition provided the ketone 129. A regioselective ring expansion of 129 provided the cyclooctenone 60. The latter was converted to the tetracyclic ketone 61 through an efficient methylenecyclopentane annulation featuring reagent 190. Ketone 61 was further elaborated to the ester 94 through a series of reactions including a palladium-catalyzed methoxycarbonylation. A chemo- and stereoselective double bond hydrogenation and subsequent carbonyl group reduction transformed 94 to the alcohol 203. Oxidation of the alcohol function of 203 provided 204. A key remote functionalization step converted 203 to 93. Chemoselective allylic oxidation of 93 produced 226, a critical intermediate for future synthetic studies. In the second part of the thesis, the generality of the newly developed cycloheptenone annulation sequence was explored. Thus, alkylation of A^N-dimethylhydrazones of general structure 261 with the bifunctional reagent 53 followed by iododestannylation and hydrolysis of the hydrazone function provided keto alkenyl iodides 262. Butyllithium mediated cyclization of 262 and oxidative rearrangement of the resultant allylic alcohols 57 provided the cycloheptenones 58. The annulation method was also extended to cyclic P-keto ester substrates. The individual reactions involved are experimentally straightforward and the overall yields of the annulation processes are good to excellent.

description: Effective and efficient regulation by government is important for economic development. Effective and efficient regulation promotes economic development, while vexatious regulation can cripple it. Many of the problems of developing countries are blamed on ineffective and inefficient government regulation. At the same time, however, understanding of the appropriate institutions and processes of the regulatory state in the context of developing countries remains underdeveloped. Studies to date tend to be of a case study nature and generalising the findings is restricted by the lack of a coherent theoretical framework. This paper attempts to develop a methodology for researching regulation in developing countries, drawing from the economics of regulation literature. The proposed methodology is deductive with empirical work used to refine and advance theory so as to develop over time a rigorous approach to researching regulation in developing economies. While there is a recognised need to ground research in the particular needs of each developing country, the paper demonstrates that the economics of regulation literature provides a useful departure point to develop such an analysis.

description: The performance and reliability of Ultra-Low-Power (ULP) computing platforms are adversely affected by environmental temperature and process variations. Mitigating the effect of these phenomena becomes crucial when these devices operate near-threshold, due to the magnification of process variations and to the strong temperature inversion effect that affects advanced technology nodes in low-voltage corners, which causes huge overhead due to margining for timing closure. Supporting an extended range of reverse and forward body-bias, UTBB FD-SOI technology provides a powerful knob to compensate for such variations. In this work we propose a methodology to maximize energy efficiency at run-time exploiting body biasing on a ULP platform operating near-threshold. The proposed method relies on on-line performance measurements by means of Process Monitoring Blocks (PMBs) coupled with an on-chip low-power body bias generator. We correlate the measurement performed by the PMBs to the maximum achievable frequency of the system, deriving a predictive model able to estimate it with an error of 9.7% at 0.7V. To minimize the effect of process variations we propose a calibration procedure that allows to use a PMB model affected by only the temperature-induced error, which reduces the frequency estimation error by 2.4x (from 9.7% to 4%). We finally propose a controller architecture relying on the derived models to automatically regulate at run-time the body bias voltage. We demonstrate that adjusting the body bias voltage against environmental temperature variations leads up to 2X reduction in the leakage power and a 15% improvement on the global energy consumption when the system operates at 0.7V and 170MHz

description: In this work, we study the in-vitro dynamics of the most malignant form of the primary brain tumor: Glioblastoma Multiforme. Typically, the growing tumor consists of the inner dense proliferating zone and the outer less dense invasive region. Experiments with different types of cells show qualitatively different behavior. Wild-type cells invade a spherically symmetric manner, but mutant cells are organized in tenuous branches. We formulate a model for this sort of growth using two coupled reaction-diffusion equations for the cell and nutrient concentrations. When the ratio of the nutrient and cell diffusion coefficients exceeds some critical value, the plane propagating front becomes unstable with respect to transversal perturbations. The instability threshold and the full phase-plane diagram in the parameter space are determined. The results are in a good agreement with experimental findings for the two types of cells.

description: The continuous cooling of a white dwarf is punctuated by events that affect its cooling rate. Probably the most significant of those is the crystallization of its core, a phase transition that occurs once the C/O interior has cooled down below a critical temperature. This transition releases latent heat as well as gravitational energy due to the redistribution of the C and O ions during solidification, thereby slowing down the evolution of the white dwarf. The unambiguous observational signature of core crystallization - a pile-up of objects in the cooling sequence - was recently reported. However, existing evolution models struggle to quantitatively reproduce this signature, casting doubt on their accuracy when used to measure the ages of stellar populations. The timing and amount of the energy released during crystallization depend on the exact form of the C/O phase diagram. Using the advanced Gibbs-Duhem integration method and state-of-the-art Monte Carlo simulations of the solid and liquid phases, we have obtained a very accurate version of this phase diagram, allowing a precise modeling of the phase transition. Despite this improvement, the magnitude of the crystallization pile-up remains underestimated by current evolution models. We conclude that latent heat release and O sedimentation alone are not sufficient to explain the observations and that other unaccounted physical mechanisms, possibly $^{22}$Ne phase separation, play an important role.

description: We describe several unexpected phenomena, caused by a solid-solid phase transition (gel-to-crystal) typical for all main classes of lipid substances - phospholipids, triglycerides, diglycerides, alkanes, etc. We discovered that this transition leads to spontaneous formation of a network of nanopores, spreading across the entire lipid structure. These nanopores are spontaneously impregnated (flooded) by water when appropriate surfactants are present, thus fracturing the lipid structure at a nano-scale. As a result, spontaneous disintegration of the lipid into nanoparticles or formation of double emulsions is observed, just by cooling and heating of an initial coarse lipid-in-water dispersion around the lipid melting temperature. The process of nanoparticle formation is effective even after incorporation of medical drugs of high load, up to 50 % in the lipid phase. The role of the main governing factors is clarified, the procedure is optimized, and the possibility for its scaling-up to industrially relevant amounts is demonstrated.

description: We study Gamow-Teller strength distributions in the neutron-deficient even isotopes (184-194)Pb in a search for signatures of deformation. The microscopic formalism used is based on a deformed quasiparticle random phase approximation (QRPA) approach, which involves a self-consistent quasiparticle deformed Skyrme Hartree-Fock (HF) basis and residual spin-isospin forces in both the particle-hole and particle-particle channels. By analyzing the sensitivity of the Gamow-Teller strength distributions to the various ingredients in the formalism, we conclude that the beta-decay of these isotopes could be a useful tool to look for fingerprints of nuclear deformation.

description: Econometric analysis of firm-level data from the recent National Survey of Innovation indicates large firms are more likely to innovate compared to small firms. Ownership structure is also found to be an important determinant of innovation - private limited and public limited firms are twice more likely to innovate compared to soleproprietorship firms. A surprising finding is the negative correlation between the propensity to innovate and the share of exports in sales. There is also no evidence that innovation is related to the extent or foreign vs. local ownership of firms. The findings on the influence of industry-level characteristics are mixed. While the influence of industry's technology level is inconclusive, the propensity to innovate is positively correlated with market concentration.
Licensing Procedures in Developing Countries: Should They Be Part of the Set-up Process?

description: Surveys have shown that, in general, developing countries tend to regulate the set-up processes for firms more intensively than developed countries. In particular, while many developing countries tend to integrate licensing requirements in the set-up process ('set-up licensing'), the more developed countries generally use licensing procedures independent of the set-up process ('independent licensing'). Set-up licensing requirements must be met before an enterprise can lawfully exist and operate in any respect. In contrast, an independent licensing system merely requires authorisation for the particular activities that are to be controlled, and this does not affect the right of the firm to exist and engage in other business activities. More importantly, set-up licensing may impose more compliance costs on entrepreneurs, more administrative costs on officials and more welfare losses on consumers than independent licensing. In this paper we explore the distinction to see whether the widespread preference for set-up licensing in developing countries can be justified on public interest grounds, or at least explained on private interest grounds.

description: As a continuum work of Bhaumik et al who derived the common eigenvector of the number-difference operator Q and pair-annihilation operator ab (J. Phys. A9 (1976) 1507) we search for the simultaneous eigenvector of Q and (ab-a^{+}b^{+}) by setting up a complex differential equation in the bipartite entangled state representation. The differential equation is then solved in terms of the two-variable Hermite polynomials and the formal hypergeometric functions. The work is also an addendum to Mod. Phys. Lett. A 9 (1994) 1291 by Fan and Klauder, in which the common eigenkets of Q and pair creators are discussed.
