description: We present a new primary transit observation of the hot-jupiter HD189733b, obtained at 3.6 microns with the Infrared Array Camera (IRAC) onboard the Spitzer Space Telescope. Previous measurements at 3.6 microns suffered from strong systematics and conclusions could hardly be obtained with confidence on the water detection by comparison of the 3.6 and 5.8 microns observations. We use a high S/N Spitzer photometric transit light curve to improve the precision of the near infrared radius of the planet at 3.6 microns. The observation has been performed using high-cadence time series integrated in the subarray mode. We are able to derive accurate system parameters, including planet-to-star radius ratio, impact parameter, scale of the system, and central time of the transit from the fits of the transit light curve. We compare the results with transmission spectroscopic models and with results from previous observations at the same wavelength. We obtained the following system parameters: R_p/R_\star=0.15566+0.00011-0.00024, b=0.661+0.0053-0.0050, and a/R_\star=8.925+0.0490-0.0523 at 3.6 microns. These measurements are three times more accurate than previous studies at this wavelength because they benefit from greater observational efficiency and less statistic and systematic errors. Nonetheless, we find that the radius ratio has to be corrected for stellar activity and present a method to do so using ground-based long-duration photometric follow-up in the V-band. The resulting planet-to-star radius ratio corrected for the stellar variability is in agreement with the previous measurement obtained in the same bandpass (Desert et al. 2009). We also discuss that water vapour could not be evidenced by comparison of the planetary radius measured at 3.6 and 5.8 microns, because the radius measured at 3.6 microns is affected by absorption by other species, possibly Rayleigh scattering by haze.

description: We investigate the long-time properties of the Ising-Glauber model on a periodic cubic lattice after a quench to zero temperature. In contrast to the conventional picture from phase-ordering kinetics, we find: (i) Domains at long time are highly interpenetrating and topologically complex, with average genus growing algebraically with system size. (ii) The long-time state is almost never static, but rather contains "blinker" spins that can flip ad infinitum with no energy cost. (iii) The energy relaxation has a complex time dependence with multiple characteristic time scales, the longest of which grows exponentially with system size.

description: We apply a model-independent, agnostic approach to the collider phenomenology of supersymmetry (SUSY), in which all mass parameters are taken as free inputs at the weak scale. We consider the gauginos, higgsinos, and the first two generations of sleptons and squarks, and analyze all possible mass hierarchies among them ($4\times 8!=161,280$ in total) in which the lightest superpartner is neutral, leading to missing energy. In each case, we identify the full set of the dominant (i.e. least suppressed by phase space, small mixing angles or Yukawa couplings) decay chains originating from the lightest colored superpartner. Our exhaustive search reveals several quite dramatic yet unexplored multilepton signatures with up to 8 isolated leptons (plus possibly up to 2 massive gauge or Higgs bosons) in the final state. Such events are spectacular, background-free for all practical purposes, and may lead to a discovery of SUSY in the very early stage ($\sim 10\ {\rm pb}^{-1}$) of LHC operations at 7 TeV.

An R package for monitoring test under density ratio model and its applications
Creators: name: Hu, Boyi
Publisher: name: University of British Columbia
Year: 2018

description: Quantiles and their functions are important population characteristics in many applications. In forestry, lower quantiles of the modulus of rapture and other mechanical properties of the wood products are important quality indices. It is important to ensure that the wood products in the market over the years meet the established industrial standards. Two well-known risk measures in finance and hydrology, value at risk (VaR) and median shortfall (MS), are quantiles of their corresponding marginal distributions. Developing effective statistical inference methods and tools on quantiles of interest is an important task in both theory and applications. When samples from multiple similar natured populations are available, Chen et al. [2016] proposed to use a density ratio model (DRM) to characterize potential latent structures in these populations. The DRM enables us to fully utilized the information contained in the data from connected populations. They further proposed a composite empirical likelihood (CEL) to avoid a parametric model assumption that is subject to model-mis-specification risk and to accommodate clustered data structure. A cluster-based bootstrap procedure was also investigated for variance estimation, construction of confidence interval and test of various hypotheses. This thesis contains complementary developments to Chen et al. [2016]. First, a user-friendly R package is developed to make their methods easy-to-use for practitioners. We also include some diagnostic tools to allow users to investigate the goodness of the fit of the density ratio model. Second, we use simulation to compare the performance DRM-CEL-based test and the famous Wilcoxin rank test for clustered data. Third, we study the performance of DRM-CEL-based inference when the data set contains observations with different cluster sizes. The simulation results show that DRM-CEL method works well in common situations.

description: We theoretically showed that the spontaneous polarization in ferroelectric (FE) nanowires (NWs) can be considerably enhanced due to the nanosize confinement by the first-principles calculations. The spontaneous polarization along the wire direction in a fully-relaxed PbTiO3 NW with 1.8 nm diameter is 1.26 times higher than that of bulk counterpart. The tension induced by NW surface curvature counteracts the near-surface depolarizing effect and meanwhile leads to the unusual enhancement of spontaneous polarization. These findings indicated that FE NWs can be promising in the applications of nanodevices.

Treatment Strategies for Motor Symptoms in Parkinson's Disease: A Systematic Review
Creators: name: Synthory AI
Publisher: name: Zenodo
Year: 2025

description: This systematic review evaluates recent advancements in treatments for motor symptoms of Parkinson's disease, focusing on pharmacological therapies, electrical neuromodulation, and exercise-based interventions. Using the Synthory.AI service, 17 studies published between 2018 and 2025 were analyzed. Pharmacological approaches, including adjunct therapies like rasagiline and ADS-5102, show efficacy in reducing OFF time and dyskinesia but highlight the need for cautious application due to adverse effects. Electrical neuromodulation techniques, such as deep brain stimulation, consistently reduce motor symptoms, though further research is needed to address methodological limitations. Exercise-based interventions demonstrate benefits in balance and cognitive function, though standardization challenges persist. These findings emphasize the importance of integrated, patient-centered strategies and call for larger, multi-center trials to enhance the generalizability of results and optimize therapeutic outcomes for Parkinson's disease patients.

description: Quantum chromodynamics (QCD) phase diagram is usually plotted as temperature (T) versus the chemical potential associated with the conserved baryon number (μ_{B}). Two fundamental properties of QCD, related to confinement and chiral symmetry, allows for two corresponding phase transitions when T and μ_{B} are varied. Theoretically the phase diagram is explored through non-perturbative QCD calculations on lattice. The energy scale for the phase diagram (Λ_{QCD} ~ 200 MeV) is such that it can be explored experimentally by colliding nuclei at varying beam energies in the laboratory. In this paper we review some aspects of the QCD phase structure as explored through the experimental studies using high energy nuclear collisions. Specifically, we discuss three observations related to the formation of a strongly coupled plasma of quarks and gluons in the collisions, experimental search for the QCD critical point on the phase diagram and freeze-out properties of the hadronic phase.

description: Orbital evolution of an interplanetary dust particle under action of an interstellar gas flow is investigated. Secular time derivatives of the particle orbital elements, for arbitrary orbit orientation, are presented. An important result concerns secular evolution of semi-major axis. Secular semi-major axis of the particle on a bound orbit decreases under the action of fast interstellar gas flow. Possible types of evolution of other Keplerian orbital elements are discussed. The paper compares influences of the Poynting-Robertson effect, the radial solar wind and the interstellar gas flow on dynamics of the dust particle in outer planetary region of the Solar System and beyond it, up to 100 AU. Evolution of putative dust ring in the zone of the Edgeworth-Kuiper belt is studied. Also non-radial solar wind and gravitational effect of major planets may play an important role. Low inclination orbits of micron-sized dust particles in the belt are not stable due to fast increase of eccentricity caused by the interstellar gas flow and subsequent planetary perturbations - the increase of eccentricity leads to planet crossing orbits of the particles. Gravitational and non-gravitational effects are treated in a way which fully respects physics. As a consequence, some of the published results turned out to be incorrect. Moreover, the paper treats the problem in a more general way than it has been presented up to now. The influence of the fast interstellar neutral gas flow might not be ignored in modeling of evolution of dust particles beyond planets.

description: Symbiotic stars, interacting binaries composed of a cool giant and a hot compact companion, exhibit complex variability across the electromagnetic spectrum. Over the past decades, large-scale photometric and spectroscopic surveys from ground- and space-based observatories have significantly advanced their discovery and characterization. These datasets have transformed the search for new symbiotic candidates, providing extensive time-domain information crucial for their classification and analysis. This review highlights recent observational results that have expanded the known population of symbiotic stars, refined classification criteria, and enhanced our understanding of their variability. Despite these advances, fundamental questions remain regarding their long-term evolution, mass transfer and accretion processes, or their potential role as progenitors of Type Ia supernovae. With ongoing and upcoming surveys, the coming years promise new discoveries and a more comprehensive picture of these intriguing interacting systems.

description: The effects of the coupling between two electronic condensates in two-gap mesoscopic superconductors are studied within the Ginzburg-Landau theory using a finite difference technique. In applied magnetic field, we derive the dependency of the size of the vortex on the sample size and the strength of the Josephson coupling. In addition, we elaborate on the dependence of the critical temperature and field on the parameters of the coupled condensates. We demonstrate further the existence and stability of fractional states, for which the two condensates comprise different vorticity. Moreover, we also found pronounced asymmetric fractional states and we show their experimentally observable magnetic response. Finally we introduce the magnetic coupling between condensates, and study in particular the case where one band is type II and the other is type I, i.e. the sample is effectively of I.x type. The calculated M(H) loops show a clear signature of the mixed type of superconductivity, which we find to be strongly affected by the ratio of the coherence lengths in the two condensates.

A multi-mass velocity dispersion model of 47 Tucanae : no evidence for an intermediate-mass black hole
Creators: name: Mann, Christopher Rhys
Publisher: name: University of British Columbia
Year: 2018

description: In this thesis we analyze stellar proper motions in the core of the globular cluster 47 Tucanae to explore the possibility of an intermediate-mass black hole (IMBH) influence on the stellar dynamics. Our use of short-wavelength photometry affords us an unprecedentedly clear view of stellar motions into the very centre of the crowded core, yielding proper motions for >50,000 stars in the central 2 arcminutes. We model the velocity dispersion profile of the cluster using an isotropic Jeans model. The density distribution is taken as a central IMBH point mass added to a combination of King profiles. We individually model the general low-mass cluster objects (main sequence/giant stars), as well as the concentrated populations of heavy binary systems and dark stellar remnants. Using un-binned likelihood model-fitting, we find that the inclusion of the concentrated populations in our model plays a crucial role in fitting for an IMBH mass. Taking into account all of these cluster sub-populations our model predicts an IMBH to cluster mass ratio of 0.06% +/- 0.13%. The concentrated binaries and stellar-mass black holes produce a sufficient enhancement to the velocity dispersion signal in the core as to make an IMBH unnecessary to fit the observations. We additionally determine that a stellar-mass black hole retention fraction of >18% becomes incompatible with our kinematic observations for 47 Tuc.

description: Laser powder bed fusion is an additive manufacturing technology that enables manufacturing complex structures with the capability of design freedom. However, owing to the essential nature of the process, it generally requires support structures. Correct selection of support structures allows a part to be manufactured successfully by avoiding inefficient heat dissipation, process-based failures, redundant material usage and long labour intense post-processes. For this purpose, alternative support structures to commercial solutions may be needed for manufacturing of the parts. In this study, different lattice-type support structures with nearly same density are investigated in terms of process simulation, manufacturing and inspection. Process simulation results indicate that the simulated lattice-type support structures exhibit similar trend with the actual ones, although up to 35% discrepancy was seen between displacement values which is a result of modeling thin and complex lattice structures. The results from manufacturing show that the lattice-type support structures present more stability than the perforated block type support structure, although they have the same density. Among the lattice-type support structures, FCC had the minimum deformation in both simulation and manufacturing results. Besides, inspection results show that the manufactured lattice structures have accurate geometrical dimensions which is consistent with its engineering design models.

description: The thermodynamic properties of the bilayer Sr$_3$Ru$_2$O$_7$ at very low temperatures are investigated by a realistic tight-binding model with the on-site interactions treated at the mean-field level. Due to the strong spin-orbit coupling, the band structure undergoes a significant change in Fermi surface topology as the external magnetic field is applied, invalidating the rigid band picture in which the Zeeman energy only causes chemical potential shifts. In addition, since Sr$_3$Ru$_2$O$_7$ is a $t_{2g}$ active system with unquenched orbital moments, the orbital Zeeman energy is not negligible and plays an important role in the phase diagram on the magnetic field orientation. We find that both the total density of states at the Fermi energy and the entropy exhibit a sudden increase near the critical magnetic field for the nematic phase, echoing the experimental findings. Our results suggest that extra cares are necessary to isolate the contributions due to the quantum criticality from the band structure singularity in this particular material. The effects of quantum critical fluctuations are briefly discussed.

On the Z-dimensional accuracy of L-powder bed fusion
Creators: name: Yasa, Evren

Publisher: name: Journal of Additive Manufacturing Technologies
Year: 2021

description: Laser Powder Bed Fusion (L-PBF) is one of the commonly utilized metal Additive Manufacturing (AM) modalities in highly demanding industries such as biomedical and aerospace. Among other limitations, the dimensional accuracy of the L-PBF parts hinders the adoption of this technology for a wider application. The dimensional accuracy in L-PBF depends on several factors such as beam compensation, process parameters, .stl conversion errors and shrinkage factors. The shrinkage factors are very important and needed to compensate for down-scaling of nominal dimensions. Due to the inherent nature of the process, anisotropic shrinkage occurs due to the thermal recession and the difference of the densities from the powder material and solidified layer. Although, it is generally taken into consideration for XY-plane dimensional accuracy, Z-shrinkage factors are omitted since the layer deposition is assumed to take care of the shrinkage for every layer in addition to deep melt pools to enable layer-to-layer fusion. However, in this study, it is observed that especially for long builds from AlSi10Mg powder material, dimensional errors up to a half of a millimeter may occur along Z-direction depending on the total Z-height. Therefore, a suitable Z-shrinkage factor is calculated based on the obtained experimental results and applied to all builds leading to a much more accurate results along the build direction. Moreover, the suitability of the shrinkage factors along X and Y axes is tested and confirmed.

description: The aluminium silicon alloy AlSi7Mg0.6 is gaining importance in additive manufacturing. This work is showing a correlation of surface quality and fatigue properties of three different AlSi7Mg0.6 as-built surfaces manufactured by laser powder bed fusion. All specimens were built in z-direction and the difference in surface quality was achieved by variation of the contour scanning parameters in the manufacturing process. Focus of the evaluation is on the reduced valley depth Svk rather than the commonly applied Ra (arithmetic mean of the line roughness profile) and Rt (maximum total height of the line roughness profile) and their areal equivalents Sa and Sz. Svk is derived from the material ratio curve and is a measure of the size of the valley population across the sample. It was found to show a better correlation with number of cycles to failure than parameters based on local extreme values such as Sz and Sv (depth of deepest detected valley).

description: Developments related to the laser powder bed fusion (L-PBF) expanded the application area of the additive manufacturing (AM) for metal alloys, and increased the variety of machines and materials. On the other hand, this increase exposed the need for process development to adapt new materials and shapes with acceptable metallurgical, mechanical and geometrical attributes. In recent years, researchers have sought to reduce the development costs by decreasing these process development needs for some requirements. Among these, modeling and simulations for residual stresses and distortions are common practices. Dedicated software for these applications provided remarkable savings in computational times. Nevertheless, it is still necessary to pay attention to finite element-based software, due to the fact that they work as black box systems. This study provides an in-depth investigation of Simufact Additive software based on L-PBF of Inconel 625 alloy. In this regard, thermo-mechanical simulations were performed by comparing the results with experimental data. Simulation set-ups were fine-tuned according to comparisons, and parametric analyses were conducted. The laser power and scanning speed were found to be the most influential parameters on the resulting residual stresses.

Additive Manufacturing technologies including 3D Printing and Direct Digital Manufacturing (DDM) complement these design approaches as the complicated geometries and manifolds produced after optimization steps are not feasible to be produced using the traditional methods of manufacturing. Although still in its infancy Generative Design (GD) has shown remarkable potential for industrial applications, particularly when coupled with 3D printing processes. Utilising generative design also has significant potential benefit for robotics as it has the capability to substantially reduce robotic arm weight whilst maintaining the overall strength. Lighter robotics systems designed using GD will allow for economical actuator solutions due to reduced motor torque requirements linked to a lighter manipulator configuration and unchanged end effector payload.

description: The Great Nebula in Carina is a superb location in which to study the physics of violent massive star-formation and the resulting feedback effects, including cloud dispersal and triggered star-formation. In order to reveal the cold dusty clouds in the Carina Nebula complex, we used the Large APEX Bolometer Camera LABOCA at the APEX telescope to map a 1.25 deg x 1.25 deg (= 50 x 50 pc^2) region at 870 micrometer. From a comparison to Halpha images we infer that about 6% of the 870 micrometer flux in the observed area is likely free-free emission from the HII region, while about 94% of the flux is very likely thermal dust emission. The total (dust + gas) mass of all clouds for which our map is sensitive is ~ 60 000 Msun, in good agreement with the mass of the compact clouds in this region derived from 13CO line observations. We generally find good agreement in the cloud morphology seen at 870 micrometer and the Spitzer 8 micrometer emission maps, but also identify a prominent infrared dark cloud. Finally, we construct a radiative transfer model for the Carina Nebula complex that reproduces the observed integrated spectral energy distribution reasonably well. Our analysis suggests a total gas + dust mass of about 200000 Msun in the investigated area; most of this material is in the form of molecular clouds, but a widely distributed component of (partly) atomic gas, containing up to ~ 50% of the total mass, may also be present. Currently, only some 10% of the gas is in sufficiently dense clouds to be immediately available for future star formation, but this fraction may increase with time owing to the ongoing compression of the strongly irradiated clouds and the expected shockwaves of the imminent supernova explosions.

description: The success of in situ alloying whilst developing high entropy alloys (HEAs) specific to the electron beam melting (EBM) process has been stated in the literature. Secondary phases forming on FCC matrix improved the mechanical properties of EBM-built; however, their random distribution limits the further improvement in mechanical performance. Herein, post-process heat treatments were designed to observe the effects on secondary phase morphology, distribution, and microhardness of EBM-built CoCrFeNiMn-0.18Ti HEA and establish the optimized heat treatments while reducing further cost. Systematic studies revealed that an increase in solutionizing time slightly enhanced the microhardness of the alloy despite the solutionizing temperature reversely affect the mechanical properties. On the one hand, reaching a solutionizing temperature of 1300°C would not be enough to dissolve all the secondary phases within a reasonable solutionizing time of two hours. Metastability of HEAs and the complex distribution of topologically formed secondary phases slowed down phase transformations through FCC matrix. On the other hand, the microhardness of samples was successfully reattributed at 600°C by annealing. Thirty minutes and fifteen hours of annealing improved the hardness of solutionized alloy by 58 and 150% while reaching 316 HV and 487 HV, respectively.

A peer-mediated intervention for middle school students with autism spectrum disorder
Creators: name: Brain, Thea
Publisher: name: University of British Columbia

description: Youth with autism spectrum disorder (ASD) are at increased risk for social isolation and loneliness. Although students with ASD are spending more time in inclusive settings at school, research has found that simply placing a student with ASD in physical proximity to typically developing peers is not sufficient to promote social gains. This study used a non-concurrent multiple-baseline, multiple-probe across participants design to investigate the effectiveness of a low-intensity, low-cost peer-mediated intervention (PMI) on social behaviours (engagement and communicative acts) for middle-school aged students with ASD during lunch breaks at school. Nine typically developing peers received less than one hour (40-50 minutes) of peer coach training. Following training, peers were encouraged to interact with their classmate with ASD during lunch breaks at school, using the strategies taught during training. Peer coaches were provided with brief feedback after each probe observation during intervention and praise only during follow-up. Results showed a functional relation between the intervention and both engagement and communicative acts, with three demonstrations of effect across participants. There was some maintenance of effect at 1-4 weeks follow-up. Social validity of this intervention was high for both peer coaches and classroom teachers. In addition, mutual enjoyment was observed for the majority of probe observation sessions across groups. This study contributes to and extends the existing PMI research by including participants between the ages of 11-13 with varying intellectual and social-communication abilities and by delivering the intervention in natural, unstructured school settings. It is important to identify evidence-based interventions that have high social validity from the perspective of school administrators, as interventions that are effective, efficient, and cost-effective are most likely to be adopted by schools.

description: Nonequilibrium molecular dynamics simulations is used to study the motion of a C60 molecule on a graphene sheet subjected to a temperature gradient. The C60 molecule is actuated and moves along the system while it just randomly dances along the perpendicular direction. Increasing the temperature gradient increases the directed velocity of C60. It is found that the free energy decreases as the C60 molecule moves toward the cold end. The driving mechanism based on the temperature gradient suggests the construction of nanoscale graphene-based motors.

description: This study was carried out in order to precisely measure the temperatures, which play an important role in reducing the errors that occur during the manufacturing of Ti6Al4V materials by the Selective laser melting method. In order to use thermal cameras in the SLM method, the thermal emissivity values of samples with different surface properties depending on the temperatures were experimentally determined. Emissivity values were determined up to a temperature of 550oC due to oxidation. Emissivity measurement was obtained by verification with the help of a surface thermocouple. Emissivity values were obtained between 0.31-0.40 in measurements depending on the surface roughness and temperatures up to 550oC. The changes in the surface properties depending on the temperature cause changes in the emissivity.

Assessing the protection provided by misclassification-based disclosure limitation methods for survey microdata

description: Government statistical agencies often apply statistical disclosure limitation techniques to survey microdata to protect the confidentiality of respondents. There is a need for valid and practical ways to assess the protection provided. This paper develops some simple methods for disclosure limitation techniques which perturb the values of categorical identifying variables. The methods are applied in numerical experiments based upon census data from the United Kingdom which are subject to two perturbation techniques: data swapping (random and targeted) and the post randomization method. Some simplifying approximations to the measure of risk are found to work well in capturing the impacts of these techniques. These approximations provide simple extensions of existing risk assessment methods based upon Poisson log-linear models. A numerical experiment is also undertaken to assess the impact of multivariate misclassification with an increasing number of identifying variables. It is found that the misclassification dominates the usual monotone increasing relationship between this number and risk so that the risk eventually declines, implying less sensitivity of risk to choice of identifying variables. The methods developed in this paper may also be used to obtain more realistic assessments of risk which take account of the kinds of measurement and other nonsampling errors commonly arising in surveys.
