description: We consider dissipative atom-cavity systems and show that their collective dynamics leads to the maximization of entanglement for intermediate values of the cavity leakage parameter $κ$. We discuss possible ways the reservoir influences entanglement. We first consider the entanglement of a single two-level atom with a microwave cavity that is coupled to another cavity. We show that the atom-cavity entanglement can be made to increase with cavity leakage. We next show that the entanglement between two atoms passing successively through a cavity can be maximised for intermediate values of $κ$. We finally consider the micromaser where the increase of two-atom entanglement for stronger cavity-environment coupling is demonstrated for experimentally attainable values of the micromaser parameters.

The droplet-scaling versus replica symmetry breaking debate in spin glasses revisited
Creators: name: Moore, M. A.
Publisher: name: arXiv

Subjects: subject: Disordered Systems and Neural Networks (cond-mat.dis-nn)
subject: FOS: Physical sciences

description: Simulational studies of spin glasses in the last decade have focussed on the so-called replicon exponent $α$ as a means of determining whether the low-temperature phase of spin glasses is described by the replica symmetry breaking picture of Parisi or by the droplet-scaling picture. On the latter picture, it should be zero, but we shall argue that it will only be zero for systems of linear dimension $L > L^*$. The crossover length $L^*$ may be of the order of hundreds of lattice spacings in three dimensions and approach infinity in 6 dimensions. We use the droplet-scaling picture to show that the apparent non-zero value of $α$ when $L < L^*$ should be $2 θ$, where $θ$ is the domain wall energy scaling exponent, This formula is in reasonable agreement with the reported values of $α$.

description: We investigate the IR spectral features of a sample of D-type symbiotic stars. Analyzing unexploited ISO-SWS data, deriving the basic observational parameters of dust bands and comparing them with respect to those observed in other astronomical sources, we try to highlight the effect of environment on grain chemistry and physic. We find strong amorphous silicate emission bands at 10 micron and 18 micron in a large fraction of the sample. The analysis of the 10 micron band, along with a direct comparison with several astronomical sources, reveals that silicate dust in symbiotic stars shows features between the characteristic circumstellar environments and the interstellar medium. This indicates an increasing reprocessing of grains in relation to specific symbiotic behavior of the objects. A correlation between the central wavelength of the 10 and 18 micron dust bands is found. By the modeling of IR spectral lines we investigate also dust grains conditions within the shocked nebulae. Both the unusual depletion values and the high sputtering efficiency might be explained by the formation of SiO moleculae, which are known to be a very reliable shock tracer. We conclude that the signature of dust chemical disturbance due to symbiotic activity should be looked for in the outer, circumbinary, expanding shells where the environmental conditions for grain processing might be achieved. Symbiotic stars are thus attractive targets for new mid-infrared and mm observations.

Distributed case management : a concept for decision support systems
Creators: name: Hofbauer, Thomas Hubert
Publisher: name: University of British Columbia
Year: 2008

description: This thesis suggests a new perspective for Decision Support Systems (DSS) that is guided by the dominant role of experience in decision making. Evidence from cognitive research supports the view that organizational problem solvers rely to a large extent on using episodic knowledge gained from similar problem solving experiences, rather than by starting from first principles every time. In addition, people tend to cooperate and seek other's experience, especially as task domains become more complex and relevant knowledge becomes more sparse. Case-Based Reasoning (CBR) has gained much appeal by utilizing previous decision making results to aid in current problem solving activities. However, existing models do not support the exchange of case-based experiences (i.e. learning from others' experience) among organizational workers. Humans are also more flexible in problem solving than existing CBR models in that they can draw analogies from various, related domains, rather than just from within one domain. Derived from both analogical reasoning (AR) and CBR methods, a DSS model based on the concept of Distributed Case Management (DCM) is proposed that would facilitate the exchange of computer-mediated experiences among organizational workers. The feasibility of this approach is demonstrated by implementing a distributed retrieval mechanism based on an analog retrieval algorithm called Analog Retrieval by Constraint Satisfaction (ARCS).

description: We propose a new geometry of optical lattice for cold atoms, namely a lattice made of a 1D stack of dark ring traps. It is obtained through the interference pattern of a standard Gaussian beam with a counter-propagating hollow beam obtained using a setup with two conical lenses. The traps of the resulting lattice are characterized by a high confinement and a filling rate much larger than unity, even if loaded with cold atoms from a MOT. We have implemented this system experimentally, and obtained a lattice of ring traps populated with typically 40 atoms per site with a life time of 30 ms. Applications in statistical physics, quantum computing and Bose-Einstein condensate dynamics are conceivable.

Revealing incentives for vertical integration in the presence of glocal policies

Publisher: name: Alma Mater Studiorum - Università di Bologna

Subjects: SECS-P/02 Politica economica

description: Local and regional policy makers are acquiring an increasingly active role in affecting firms’ specialization decisions that in turn influence firms’ vertical organization. We analyse the relation between vertical integration incentives and trade liberalization in the presence of glocal policies, i.e., specific (local) policies that have international (global) impact.
More precisely, one of the most important reasons for vertical integration in the presence of sunk costs of specialization is avoiding the risk of hold up. We introduce the idea that this sunk cost can be manipulated by the policy maker at national/regional/local level. We characterize the conditions under which policies are effective in achieving a particular equilibrium in terms
of vertical structure and specialization decision. The main result is that the policy effectiveness is stronger the higher is the importance of the hold-up problem. In particular, we investigate how glocal policies interact with policies that affect the market openness (trade policy). We find that for high values of the specialization upgrade cost, trade policies are ineffective. At the same
time, if the trading cost is very low, glocal policies are ineffective. Finally, in the presence of intermediate specialization upgrade and trading cost, either policy supplements the other policy.

description: In-situ measurements carried out by spacecraft in radial alignment are critical to advance our knowledge on the evolutionary behavior of coronal mass ejections (CMEs) and their magnetic structures during propagation through interplanetary space. Yet, the scarcity of radially aligned CME crossings restricts investigations on the evolution of CME magnetic structures to a few case studies, preventing a comprehensive understanding of CME complexity changes during propagation. In this paper, we perform numerical simulations of CMEs interacting with different solar wind streams using the linear force-free spheromak CME model incorporated into the EUropean Heliospheric FORecasting Information Asset (EUHFORIA) model. The novelty of our approach lies in the investigation of the evolution of CME complexity using a swarm of radially aligned, simulated spacecraft. Our scope is to determine under which conditions, and to what extent, CMEs exhibit variations of their magnetic structure and complexity during propagation, as measured by spacecraft that are radially aligned. Results indicate that the interaction with large-scale solar wind structures, and particularly with stream interaction regions, doubles the probability to detect an increase of the CME magnetic complexity between two spacecraft in radial alignment, compared to cases without such interactions. This work represents the first attempt to quantify the probability of detecting complexity changes in CME magnetic structures by spacecraft in radial alignment using numerical simulations, and it provides support to the interpretation of multi-point CME observations involving past, current (such as Parker Solar Probe and Solar Orbiter), and future missions.

description: We report on multi-wavelength observations spanning radio to X-ray wavelengths of the M dwarf flare star, EV Lacertae, probing the characteristics of the outer atmospheric plasma from the upper chromosphere to the corona. We detect the star at a wavelength of 2 cm (15 GHz) for the first time. UV and FUV line profiles show evidence of nonthermal broadening, and the velocity width appear to peak at lower temperatures than in the Sun; this trend is confirmed in another active M dwarf flare star. Electron density measurements indicate nearly constant electron pressures between $\log T=$5.2 and 6.4. At higher coronal temperatures, there is a sharp increase of two orders of magnitude in density (n$_{e}\sim10^{13}$ cm$^{-3}$ at $\log T=$6.9). X-ray, EUV, FUV and NUV spectra constrain the DEM from the upper chromosphere through the corona. The coronal pressures are inconsistent with the assumption of hydrostatic equilibrium, either through EM modeling or application of scaling laws, and imply large conductive loss rates and a large energy input at the highest temperatures. The timescales for radiative and conductive losses in EV Lac's upper atmosphere imply that significant continued heating must occur for the corona to maintain its quiescent properties. The high frequency radio detection requires the high temperature X-ray-emitting coronal plasma to be spatially distinct from the radio emission source. Length scales in the low-temperature corona are markedly larger than those in the high-temperature corona, further suggestions of an inhomogeneous mixture of thermal and nonthermal coronal plasma.

description: We have systematically studied the transport properties of the La$_{2-x}$Y$_{x}$CuO$_{4}$(LYCO) films of T'-phase ($0.05\leq x \leq 0.30$). In this nominally "undoped" system, superconductivity was acquired in certain Y doping range ($0.10\leq x \leq 0.20$). Measurements of resistivity, Hall coefficients in normal states and resistive critical field ($H^ρ_{c2}$)in superconducting states of the T'-LYCO films show the similar behavior as the known Ce-doped n-type cuprate superconductors, indicating the intrinsic electron-doping nature. The charge carriers are induced by oxygen deficiency. Non-superconducting Y-doped Pr- or Nd-based T'-phase cuprate films were also investigated for comparison, suggesting the crucial role of the radii of A-site cations in the origin of superconductivity in the nominally "undoped" cuptates. Based on a reasonable scenario in the microscopic reduction process, we put forward a self-consistent interpretation of these experimental observations.

description: Various autonomous or assisted driving strategies have been facilitated through the accurate and reliable perception of the environment around a vehicle. Among the commonly used sensors, radar has usually been considered as a robust and cost-effective solution even in adverse driving scenarios, e.g., weak/strong lighting or bad weather. Instead of considering to fuse the unreliable information from all available sensors, perception from pure radar data becomes a valuable alternative that is worth exploring. In this paper, we propose a deep radar object detection network, named RODNet, which is cross-supervised by a camera-radar fused algorithm without laborious annotation efforts, to effectively detect objects from the radio frequency (RF) images in real-time. First, the raw signals captured by millimeter-wave radars are transformed to RF images in range-azimuth coordinates. Second, our proposed RODNet takes a sequence of RF images as the input to predict the likelihood of objects in the radar field of view (FoV). Two customized modules are also added to handle multi-chirp information and object relative motion. Instead of using human-labeled ground truth for training, the proposed RODNet is cross-supervised by a novel 3D localization of detected objects using a camera-radar fusion (CRF) strategy in the training stage. Finally, we propose a method to evaluate the object detection performance of the RODNet. Due to no existing public dataset available for our task, we create a new dataset, named CRUW, which contains synchronized RGB and RF image sequences in various driving scenarios. With intensive experiments, our proposed cross-supervised RODNet achieves 86% average precision and 88% average recall of object detection performance, which shows the robustness to noisy scenarios in various driving conditions.

description: We investigate the dust attenuation in both stellar populations and ionized gas in kpc-scale regions in nearby galaxies, using integral field spectroscopy data from MaNGA MPL-9. We identify star-forming (HII) and diffuse ionized gas (DIG) regions from MaNGA datacubes. From the stacked spectrum of each region, we measure the stellar attenuation, $E(B-V)_{\rm star}$, using the technique developed by Li et al.(2020), as well as the gas attenuation, $E(B-V)_{\rm gas}$, from the Balmer decrement. We then examine the correlation of $E(B-V)_{\rm star}$, $E(B-V)_{\rm gas}$, $E(B-V)_{\rm gas}-E(B-V)_{\rm star}$ and $E(B-V)_{\rm star}/E(B-V)_{\rm gas}$ with 16 regional/global properties, and for regions with different $\rm Hα$ surface brightnesses ($Σ_{\rm Hα}$). We find a stronger correlation between $E(B-V)_{\rm star}$ and $E(B-V)_{\rm gas}$ in regions of higher $Σ_{\rm Hα}$. Luminosity-weighted age ($t_L$) is found to be the property that is the most strongly correlated with $E(B-V)_{\rm star}$, and consequently with $E(B-V)_{\rm gas}-E(B-V)_{\rm star}$ and $E(B-V)_{\rm star}/E(B-V)_{\rm gas}$. At fixed $Σ_{\rm Hα}$, $\log_{10}t_L$ is linearly and negatively correlated with $E(B-V)_{\rm star}/E(B-V)_{\rm gas}$ at all ages. Gas-phase metallicity and ionization level are important for the attenuation in the gas. Our results indicate that the ionizing source for DIG regions is likely distributed in the outer-skirt of galaxies, while for HII regions our results can be well explained by the two-component dust model of Charlot & Fall (2000).

description: We investigate the time-dependent perturbations of strongly coupled $\mathcal{N} = 4$ SYM theory at finite temperature and finite chemical potential with a second order phase transition. This theory is modelled by a top-down Einstein-Maxwell-dilaton description which is a consistent truncation of the dimensional reduction of type IIB string theory on AdS$_5\times$S$^5$. We focus on spin-1 and spin-2 sectors of perturbations and compute the linearized hydrodynamic transport coefficients up to the third order in gradient expansion. We also determine the radius of convergence of the hydrodynamic mode in spin-1 sector and the lowest non-hydrodynamic modes in spin-2 sector. Analytically, we find that all the hydrodynamic quantities have the same critical exponent near the critical point $θ= 1/2$. Moreover, we establish a relation between symmetry enhancement of the underlying theory and vanishing the only third order hydrodynamic transport coefficient $θ_1$, which appears in the shear dispersion relation of a conformal theory on a flat background.

description: We present the first colour-magnitude relation (CMR) of early-type galaxies in the central region of the Antlia cluster, obtained from CCD wide-field photometry in the Washington photometric system. Integrated (C -T1) colours, T1 magnitudes, and effective radii have been measured for 93 galaxies (i.e. the largest galaxies sample in the Washington system till now) from the FS90 catalogue (Ferguson & Sandage 1990). Membership of 37 objects can be confirmed through new radial velocities and data collected from the literature. The resulting colour-magnitude diagram shows that early-type FS90 galaxies that are spectroscopically confirmed Antlia members or that were considered as definite members by FS90, follow a well defined CMR (sigma_(C -T1) ~ 0.07 mag) that spans 9 magnitudes in brightness with no apparent change of slope. This relation is very tight for the whole magnitude range but S0 galaxies show a larger dispersion, apparently due to a separation of ellipticals and S0s. Antlia displays a slope of -13.6 in a T1 vs. (C -T1) diagram, in agreement with results for clusters like Fornax, Virgo, Perseus and Coma, which are dynamically different to Antlia. This fact might indicate that the build up of the CMR in cluster of galaxies is more related to galaxies internal processes than to the influence of the environment. Interpreting the CMR as a luminosity-metallicity relation of old stellar systems, the metallicities of the Antlia galaxies define a global relation down to Mv ~ -13. We also find, for early-type dwarfs, no clear relation between luminosity and effective radius, indicating a nearly constant mean effective radius of ~ 1 kpc. This value is also found in several samples of dwarf galaxies in Virgo and Coma.

description: Measurements of CMB anisotropy and, more recently, polarization have played a very important role allowing precise determination of various parameters of the `standard' cosmological model. The expectation of the paradigm of inflation and the generic prediction of the simplest realization of inflationary scenario in the early universe have also been established -- `acausally' correlated initial perturbations in a flat, statistically isotropic universe, adiabatic nature of primordial density perturbations. Direct evidence for gravitational instability mechanism for structure formation from primordial perturbations has been established. In the next decade, future experiments promise to strengthen these deductions and uncover the remaining crucial signature of inflation -- the primordial gravitational wave background.

description: Recent studies of silicon spin qubits at temperatures above 1 K are encouraging demonstrations that the cooling requirements for solid-state quantum computing can be considerably relaxed. However, qubit readout mechanisms that rely on charge sensing with a single-island single-electron transistor (SISET) quickly lose sensitivity due to thermal broadening of the electron distribution in the reservoirs. Here we exploit the tunneling between two quantised states in a double-island SET (DISET) to demonstrate a charge sensor with an improvement in signal-to-noise by an order of magnitude compared to a standard SISET, and a single-shot charge readout fidelity above 99 % up to 8 K at a bandwidth > 100 kHz. These improvements are consistent with our theoretical modelling of the temperature-dependent current transport for both types of SETs. With minor additional hardware overheads, these sensors can be integrated into existing qubit architectures for high fidelity charge readout at few-kelvin temperatures.

description: By developing the multidimensional model of IHRM practice localization and autonomy, this study provides a more comprehensive framework of the typology and antecedents of IHRM study within the tension between global integration and local responsiveness. In order to answer the research question to explore the types of IHRM in multinational corporations from emerging economies, and the key factors that influence MNCs’ IHRM patterns, this study adopts a multiple case study approach with 9 subsidiaries (from 7 Chinese MNCs) operating in UK. A key insight is that there are different IHRM patterns exercised by Chinese MNCs with the combination of different levels of HRM practice localization and HRM autonomy. The various IHRM patterns are represented by six HRM strategies including global, transnational, opportunistic dual, passive dual, confederate, and multidomestic HRM. These specified IHRM types particularly contribute to the empirical IHRM typology studies in the context of EMNCs. A second insight reveals that the variance of IHRM patterns can be explained from both the corporate’s aspect including MNCs’ integrative capabilities and international strategies, and the subsidiaries’ aspect including subsidiaries’ entry mode and their resource dependence on parent company. Such relationships enrich our understanding of MNCs’ IHRM in institutional theory, resource-based and resource dependence theories. Moreover, this study extends IHRM research in the context of emerging countries using China as an example which also provides contextual and cultural explanations for the specific IHRM strategies found in this study.

description: The possibility of achieving highly selective excitation of low metastable states of hydrogen and helium atoms by using short laser pulses with reasonable parameters is demonstrated theoretically. Interactions of atoms with the laser field are studied by solving the close-coupling equations without discretization. The parameters of laser pulses are calculated using different kinds of optimization procedures. For the excitation durations of hundreds of femtoseconds direct optimization of the parameters of one and two laser pulses with Gaussian envelopes is used to introduce a number of simple schemes of selective excitation. To treat the case of shorter excitation durations, optimal control theory is used and the calculated optimal fields are approximated by sequences of pulses with reasonable shapes. A new way to achieve selective excitation of metastable atomic states by using sequences of attosecond pulses is introduced.

description: The isothermal magnetoresistance (MR) with magnetic field (H) parallel to and perpendicular to ab plane is systematically studied on the single crystal Na$_{0.52}$CoO$_2$ with charge ordering at $\sim 50$ K and an in-plane ferromagnetism below 25 K. The isothermal MR behavior with H $\parallel$ ab plane and H $\perp$ ab plane is quite different. When H $\parallel$ ab plane, the MR is always negative and the in-plane ferromagnetic behavior is enhanced. While the MR with H $\perp$ ab plane changes from negative to positive with decreasing temperature or increasing H, and the in-plane ferromagnetic behavior is suppressed. A striking feature is that the MR with H $\perp$ ab plane shows a hysteresis behavior below 25 K, which is absent for the case of H $\parallel$ ab plane. These results provide strong evidence for a spin-flop transition of small moments of Co$^{3.5-δ}$ sites induced by H $\perp$ ab plane, leading to a metamagnetic transition for small moments of Co$^{3.5-δ}$ sites. These complex magnetism suggests an unconventional superconductivity in Na$_x$CoO$_2$ system because the Na$_x$CoO$_2$ around x=0.5 is considered to be the parent compound of superconductivity.

description: We consider the possibility that the total dark energy (DE) of the Universe is made out of two dynamical components of different nature: a variable cosmological term, Lambda, and a dynamical ``cosmon'', X, possibly interacting with Lambda but not with matter -- which remains conserved. We call this scenario the LXCDM model. One possibility for X would be a scalar field, but it is not the only one. The overall equation of state (EOS) of the LXCDM model can effectively appear as quintessence or phantom energy depending on the mixture of the two components. Both the dynamics of Lambda and of X could be linked to high energy effects near the Planck scale. In the case of Lambda it may be related to the running of this parameter under quantum effects, whereas X might be identified with some fundamental field (say, a dilaton) left over as a low-energy ``relic'' by e.g. string theory. We find that the dynamics of the LXCDM model can trigger a future stopping of the Universe expansion and can keep the ratio rho_D/rho_m (DE density to matter-radiation density) bounded and of order 1. Therefore, the model could explain the so-called ``cosmological coincidence problem''. This is in part related to the possibility that the present value of the cosmological term can be Lambda<0 in this framework (the current total DE density nevertheless being positive). However, a cosmic halt could occur even if Lambda>0 because of the peculiar behavior of X as ``Phantom Matter''. We describe various cosmological scenarios made possible by the composite and dynamical nature of LXCDM, and discuss in detail their impact on the cosmological coincidence problem.

The relationship between interpersonal problems and negative childhood experiences
Creators: name: During, Sara May
Publisher: name: University of British Columbia

description: The purpose of this investigation was to examine the relationship between adult interpersonal functioning of women, currently in therapy wherein they were addressing unresolved issues about their childhood maltreatment, and childhood experiences referring to a developmental psychopathology framework. One hundred and twenty women (30 sexual abuse, 30 physical abuse, 30 family disruption, and 30 control) were individually presented with a series of audiotapes of three interpersonal situations (conflictual, neutral, dating), and asked to record their self-report of physiological response, self- and other-perceptions and coping responses. Physiological indices (heart rate, systolic and diastolic blood pressure) were also recorded, as well as self-report of childhood coping strategies. The data were examined as to whether abuse survivors in therapy addressing their childhood experiences have more interpersonal problems than non-clinical control subjects or than individuals having other types of traumatic backgrounds and whether any noted interpersonal difficulties are specific to the type of abuse, or general in nature. Results indicated that abusive experiences are related to greater dysfunction in regards to self- and other-perceptions than exposure to disruptive/chaotic family environments alone. However, the differences appear to be variable-specific and few differences were obtained on physiological and coping variables. Some specific problems in adult interpersonal functioning were evidenced between the sexual and physical abuse groups. Specifically, in comparison to the physical abuse survivors, sexual abuse survivors reported greater use of different, and perhaps less adaptive, coping strategies in neutral situations. No other dependent variables significantly differed between the two groups. The results were discussed in terms of theoretical and empirical issues related to abuse-specific outcomes, the specific methodology employed in this study, and directions for future research.
A note on the exchangeability condition in Stein's method

description: We show by a surprisingly simple argument that the exchangeability condition, which is key to the exchangeable pair approach in Stein's method for distributional approximation, can be omitted in many standard settings. This is achieved by replacing the usual antisymmetric function by a simpler one, for which only equality in distribution is required. In the case of normal approximation we also slightly improve the constants appearing in previous results. For Poisson approximation, a different antisymmetric function is used, and additional error terms are needed if the bound is to be extended beyond the exchangeable setting.

description: Highly ordered periodic arrays of silver nanoparticles have been fabricated which exhibit surface plasmon resonances in the visible spectrum. We demonstrate the ability of these structures to alter the fluorescence properties of vicinal dye molecules by providing an additional radiative decay channel. Using fluorescence lifetime imaging microscopy, we have created high resolution spatial maps of the molecular lifetime components; these show an order of magnitude increase in decay rate from a localized volume around the nanoparticles, resulting in a commensurate enhancement in the fluorescence emission intensity. Spatial maps of the Raman scattering signal from molecules on the nanoparticles shows an enhancement of more than 5 orders of magnitude.

description: Atomically precise dopant arrays in Si are being pursued for solid-state quantum computing applications. We propose a guided self-assembly process to produce atomically precise arrays of single dopant atoms in lieu of lithographic patterning. We leverage the self-assembled c(4x2) structure formed on Br- and I-Si(100) and investigate molecular precursor adsorption into the generated array of single-dimer window (SDW) adsorption sites with density functional theory (DFT). The adsorption of several technologically relevant dopant precursors (PH$_3$, BCl$_3$, AlCl$_3$, GaCl$_3$) into SDWs formed with various resists (H, Cl, Br, I) are explored to identify the effects of steric interactions. PH$_3$ adsorbed without barrier on all resists studied, while BCl$_3$ exhibited the largest adsorption barrier, 0.34 eV, with an I resist. Dense arrays of AlCl$_3$ were found to form within experimentally realizable conditions demonstrating the potential for the proposed use of guided self-assembly for atomically precise fabrication of dopant-based devices.

Growth processes related to the dispersionless Lax equations

description: This paper is a short review of the connection between certain types of growth processes and the integrable systems theory, written from the viewpoint of the latter. Starting from the dispersionless Lax equations for the 2D Toda hierarchy, we interpret them as evolution equations for conformal maps in the plane. This provides a unified approach to evolution of smooth domains (such as Laplacian growth) and growth of slits. We show that the Löwner differential equation for a parametric family of conformal maps of slit domains arises as a consistency condition for reductions of the dispersionless Toda hierarchy. It is also demonstrated how the both types of growth processes can be simulated by the large $N$ limit of the Dyson gas picture for the model of normal random matrices.

Two papers in international trade
Creators: name: Fullerton, John Michael
Publisher: name: University of British Columbia
Year: 2008

description: This thesis presents two papers dealing with international trade policy in North America. The first is "An Empirical Analysis of Protectionist Forces in the United States and Canada" and the second is "Imports as a Cause of Injury: the Case of the 1986 Softwood Lumber Dispute". The first paper addresses the question of what motivates firms and industries to initiate "less than fair value" (LFV) complaints. The theory of rent-seeking is tested by analyzing data on the frequency of countervailing duty and antidumping complaints from 1975 to 1987 in both Canada and the U.S. A reduced form model is specified that expUcitly incorporates factors that are assumed to affect the supply and demand for protection, including federal elections, business cycles, and statutory changes to laws governing antidumping and countervailing duty procedures. The results indicate that the frequency of LFV cases, in both the U.S. and Canada, rise during low points in the business cycle, and when relative competitiveness and profitability in manufacturing decline. The second paper takes a specific countervailing duty case, that of the Canada-U.S. softwood lumber dispute of 1986, and addresses the question of whether the U.S. industry suffered injury from the alleged less than fair valued Canadian lumber imports. The relationship between various measures of injury for the U.S. industry and various hypothesized causal factors, including stumpage prices, is analyzed. The six measures of injury are: prices, output, market share, employment, accounting profits, and stock market profits. Structural models are specified and reduced form models tested for the 1975 to 1987 time period. The analysis indicates that stumpage prices, as proxied by B.C. stumpage levels, appear to have had littie effect on any injury sustained by the U.S. industry. Alternative specifications, using "leaked rents" to the B.C. industry as a proxy for the alleged subsidy, also showed little effect on the U.S. industry. Business cycle effects and the exchange rate are the most important determinants of performance. Counterfactual simulations using tiie estimated equations permit the hypothesizing of how the U.S. industry would have fared under alternative economic scenarios. This provides a useful framework for evaluating causes of injury, since one can control for all other factors besides those alleged to be unfair.

Video Surveillance System

description: Nowadays, people depend on security systems to safeguard their belongings, making safety and security top priorities. A smart CCTV surveillance system with intrusion detection is proposed in this proposal. It integrates face recognition to verify users and uses numerous USB cameras for live streaming and monitoring. The system notifies the owner via email, SMS, and a snapshot when it detects an unknown face. Computers and cellphones may both view live camera feeds. The system offers improved functionality for residences, shops, and shopping centers by utilizing IP technology and intelligent picture analysis. Face recognition technology enhances surveillance efficiency by reducing false alarms and improving real-time threat detection. Moreover, integrating multiple security layers, such as motion detection and behavior analysis, can further enhance security measures. The focus of this study is on creating a cutting-edge, effective security solution.
Testing gravity of a disformal Kerr black hole in quadratic degenerate higher-order scalar-tensor theories by quasi-periodic oscillations

description: By using the relativistic precession model, we have studied frequencies of quasi-periodic oscillations in the spacetime of a disformal Kerr black hole. This black hole owns an extra disformal parameter and belongs to a class of non-stealth solutions in quadratic degenerate higher-order scalar-tensor (DHOST) theories. Our result shows that only the periastron precession frequency is related to the disformal parameter, while the azimuthal frequency and the nodal precession frequency are identical with those in the usual Kerr black hole in general relativity. Combing with the observation data of GRO J1655-40, we fit parameters of the disformal Kerr black hole, and find that the disformal parameter $α$ is almost negative in the range of $1 σ$, which implies the negative disformal parameter $α$ is favored by the observation data of GRO J1655-40.

description: Accurate astrometry and photometry of saturated and coronagraphic point spread functions (PSFs) are fundamental to both ground- and space-based high contrast imaging projects. For ground-based adaptive optics imaging, differential atmospheric refraction and flexure introduce a small drift of the PSF with time, and seeing and sky transmission variations modify the PSF flux distribution. For space-based imaging, vibrations, thermal fluctuations and pointing jitters can modify the PSF core position and flux. These effects need to be corrected to properly combine the images and obtain optimal signal-to-noise ratios, accurate relative astrometry and photometry of detected objects as well as precise detection limits. Usually, one can easily correct for these effects by using the PSF core, but this is impossible when high dynamic range observing techniques are used, like coronagrahy with a non-transmissive occulting mask, or if the stellar PSF core is saturated. We present a new technique that can solve these issues by using off-axis satellite PSFs produced by a periodic amplitude or phase mask conjugated to a pupil plane. It will be shown that these satellite PSFs track precisely the PSF position, its Strehl ratio and its intensity and can thus be used to register and to flux normalize the PSF. A laboratory experiment is also presented to validate the theory. This approach can be easily implemented in existing adaptive optics instruments and should be considered for future extreme adaptive optics coronagraph instruments and in high-contrast imaging space observatories.
