description: The computational design of soft underwater swimmers is challenging because of the high degrees of freedom in soft-body modeling. In this paper, we present a differentiable pipeline for co-designing a soft swimmer's geometry and controller. Our pipeline unlocks gradient-based algorithms for discovering novel swimmer designs more efficiently than traditional gradient-free solutions. We propose Wasserstein barycenters as a basis for the geometric design of soft underwater swimmers since it is differentiable and can naturally interpolate between bio-inspired base shapes via optimal transport. By combining this design space with differentiable simulation and control, we can efficiently optimize a soft underwater swimmer's performance with fewer simulations than baseline methods. We demonstrate the efficacy of our method on various design problems such as fast, stable, and energy-efficient swimming and demonstrate applicability to multi-objective design.

description: We study the interaction between two adjacent but electrically isolated quantum point contacts (QPCs). At high enough source-drain bias on one QPC, the drive QPC, we detect a finite electric current in the second, unbiased, detector QPC. The current generated at the detector QPC always flows in the opposite direction than the current of the drive QPC. The generated current is maximal, if the detector QPC is tuned to a transition region between its quantized conductance plateaus and the drive QPC is almost pinched-off. We interpret this counterflow phenomenon in terms of an asymmetric phonon-induced excitation of electrons in the leads of the detector QPC.

description: We investigate the shot noise limited sensitivity of a four-mirror cavity enhanced Michelson interferometer. The intention of this interferometer topology is the reduction of thermal lensing and the impact of the interferometers contrast although transmissive optics are used with high circulating powers. The analytical expressions describing the light fields and the frequency response are derived. Although the parameter space has 11 dimensions, a detailed analysis of the resonance feature gives boundary conditions allowing systematic parameter studies.

description: The Archigram archival project made the works of seminal experimental architectural group Archigram available free online for an academic and general audience. It was a major archival work, and a new kind of digital academic archive, displaying material held in different places around the world and variously owned. It was aimed at a wide online design community, discovering it through Google or social media, as well as a traditional academic audience. It has been widely acclaimed in both fields. The project has three distinct but interlinked aims: firstly to assess, catalogue and present the vast range of Archigram's prolific work, of which only a small portion was previously available; secondly to provide reflective academic material on Archigram and on the wider picture of their work presented; thirdly to develop a new type of non-ownership online archive, suitable for both academic research at the highest level and for casual public browsing. The project hybridised several existing methodologies. It combined practical archival and editorial methods for the recovery, presentation and contextualisation of Archigram's work, with digital web design and with the provision of reflective academic and scholarly material. It was designed by the EXP Research Group in the Department of Architecture in collaboration with Archigram and their heirs and with the Centre for Parallel Computing, School of Electronics and Computer Science, also at the University of Westminster. It was rated 'outstanding' in the AHRC's own final report and was shortlisted for the RIBA research awards in 2010. It received 40,000 users and more than 250,000 page views in its first two weeks live, taking the site into twitter’s Top 1000 sites, and a steady flow of visitors thereafter. Further statistics are included in the accompanying portfolio. This output will also be returned to by Murray Fraser for UCL.

description: In Heisenberg models with exchange anisotropy, transverse spin components are not conserved and can decay not only by transport, but also by dephasing. Here we utilize ultracold atoms to simulate the dynamics of 1D Heisenberg spin chains, and observe fast, local spin decay controlled by the anisotropy. Additionally, we directly observe an effective magnetic field created by superexchange which causes an inhomogeneous decay mechanism due to variations of lattice depth between chains, as well as dephasing within each chain due to the twofold reduction of the effective magnetic field at the edges of the chains and due to fluctuations of the effective magnetic field in the presence of mobile holes. The latter is a new coupling mechanism between holes and magnons. All these dephasing mechanisms, corroborated by extensive numerical simulations, have not been observed before with ultracold atoms and illustrate basic properties of the underlying Hubbard model.

The ratio of PAH features and rest frame far-infrared emission is the same as in lower luminosity star forming ultraluminous infrared galaxies and in local PG QSOs, supporting a predominantly starburst nature of the Cloverleaf's huge far-infrared luminosity (5.4E12 Lsun, corrected for lensing). The Cloverleaf's period of dominant QSO activity (Lbol ~ 7E13 Lsun) is coincident with an intense (star formation rate ~1000 Msun/yr) and short (gas exhaustion time ~3E7yr) star forming event.

description: Acidophiles play a vital catalytic role in the formation of acid mine drainage (AMD). In this study, acidophilic communities in a stream, two lakes and five ponds in Nanshan Mine, Anhui Province, China were comparatively investigated. Among the three types of AMDs, the stream which originated from a rock wall had the strongest acidity (pH 2.30–2.42), while the ponds (pH 2.35–2.60) formed in mine dump and the two large-scale AMD lakes (pH 2.66–3.05) were less acidic. The chemolithotrophic iron-oxidizer Leptospirillum dominated at the stream starting point with the lowest pH and highest Fe content. However, with streamflow, pH increased and Fe concentration decreased dramatically, and the dominance of Leptospirillum was replaced by the less acid-resistant iron-oxidizer Ferrovum. In contrast to the stream, prokaryotic communities in the ponds were mostly dominated by chemoheterotrophic Acidiphilium because of the abundant organic matter from surrounding mine waste. Both chemolithotrophic Ferrovum and chemoheterotrophic Acidiphilium were abundant in the AMD lakes, which may form a symbiotic relationship around the carbon cycle. Statistical analyses indicated that pH was the predominant environmental factor influencing the prokaryotic communities. As for the eukaryotic communities, the microeukaryotes in the stream were mostly uncultured groups. Both photoautotrophic algae Chrysonebula and chemoheterotrophic fungi were abundant in the ponds, while the two AMD lakes were only dominated by photoautotrophic algae Coccomyxa and Ochromonas.

Compact Converters using GaN HEMTs for Pulsed Power Applications-Slides
Creators: Harish Krishnamoorthy
Publisher: name: IEEE
Year: 2023

PELS Webinar Slides
Abstract: Pulsed power applications require the delivery of high-energy pulses in a controlled and efficient manner. Power converters need to be specifically designed to meet the demanding requirements of pulsed power systems, providing precise voltage and current regulation, fast switching capabilities, and high power density. Power supplies for pulsed power applications contribute to the advancement of various fields, including aerospace, defense, medical, and subsurface characterization.
This talk will begin with the introduction of major pulsed power applications and then focus on two of the critical ones � radar and nuclear magnetic resonance (NMR) spectroscopy � from a power conversion perspective. Then, the speaker will detail a 2-stage converter architecture and the design of the individual stages (isolated and non-isolated) using GaN HEMTs for these applications. This will be followed by a description of the challenges faced while designing compact (micro 100 W/in3), fast (less than 1 microsecond load transients), and high-temperature (greater than 150 degrees C) capable pulsed power supplies. The talk will conclude by discussing some preliminary results from the thermal cycling tests conducted on the GaN devices and the characterization of their effective activation energy.

description: Being far away from friends and family, and sometimes facing hardships at work and in society, foreign domestic workers in Hong Kong have a strong need for access to social space to gather together and to empower each other. At the same time, social space can satisfy their needs for privacy, which has been stripped away from them due to the mandatory live-in rule in the employer’s home. In view of this, we devised an explorative case study to probe into the significance and usage patterns of social space by foreign domestic workers and report our findings using their own statements and experiences. We found that the dual-functional social space is an important physical attribute that aided the development of their social identity, and that they have achieved partial success in sharing—or taking over—the social space that was never intended for the sake of their well-being.
Towards a framework for identifying propulsive industries in advanced metropolitan economies
Creators: name: Kahnert, Brian Joseph
Publisher: name: University of British Columbia
Year: 2010

description: The role of industries and firms in propelling urban economic growth and change is an important issue in urban economic research and policy. A framework for identifying propulsive industries in advanced metropolitan economies is proposed. A propulsive industry is a set of firms, producing substitutable goods or services, which significantly influences urban economic growth and change. The framework examines the opportunities and limits in identifying propulsive industries using existing concepts and data from urban, regional and industrial economic research. Initially, industry characteristics propelling urban economic growth and change are described. These characteristics fall into two categories: propulsive mechanisms which directly stimulate urban income and employment growth; and economic factors which cause propulsive mechanisms to change over time. The analysis shows how nine characteristics can be turned into criteria for identifying local propulsive industries: industry size, growth performance, average employee earnings, occupational profile, multiplier performance, export orientation, vulnerability to import penetration of domestic markets, and sensitivity to economic recession and expansion. Two additional industry characteristics are rejected as criteria for identifying propulsive industries because of inadequate quantitative measures (innovation intensity, and match of occupational demand with local unemployment). A third, industry concentration, is rejected because, of uncertainty in the propulsive relationship with urban economic growth and change. The efficacy of using available data for identifying propulsive industries in metropolitan Vancouver, British Columbia is examined. Data are available for five out of the nine proposed criteria: industry size, net employment growth, average weekly wages, and sensitivity to economic recession and expansion. A provisional ranking of propulsive industries using these five criteria shows the dominant role of services in the metropolitan Vancouver economy. Finally, findings on the opportunities and limits for identifying local propulsive industries and implications for urban economic policy are discussed. The nine proposed criteria provide a more comprehensive and analytical approach for identifying propulsive industries than methods presently used by local economic policymakers. Available data are, however, inadequate for identifying propulsive industries in metropolitan Vancouver. Information on local propulsive industries can be used to set priorities among an increasingly complex and diverse array of urban economic growth programs; evaluate the efficacy of implemented programs; and monitor and evaluate changes in urban economic structure. Metropolitan governments could provide a vital forum for economic research and policy initiatives involving the identification and support of local propulsive industries.

description: Using X-ray tomography, we experimentally investigate granular packings subject to mechanical tapping for three types of beads with different friction coefficients. We validate Edwards volume ensemble in these three-dimensional granular systems and establish a granular version of thermodynamic zeroth law. Within Edwards framework, we also explicitly clarify how friction influences granular statistical mechanics as modifying the density of states, which allows us to determine the entropy as a function of packing fraction and friction subsequently. Additionally, we obtain a granular jamming phase diagram based on geometric coordination number and packing fraction.

description: The spatial distribution of energetic protons contributes towards the understanding of magnetospheric dynamics. Based upon 17 years of the Cluster/RAPID observations, we have derived machine learning-based models to predict the proton intensities at energies from 28 to 1,885 keV in the 3D terrestrial magnetosphere at radial distances between 6 and 22 RE. We used the satellite location and indices for solar, solar wind and geomagnetic activity as predictors. The results demonstrate that the neural network (multi-layer perceptron regressor) outperforms baseline models based on the k-Nearest Neighbors and historical binning on average by ~80% and ~33\%, respectively. The average correlation between the observed and predicted data is about 56%, which is reasonable in light of the complex dynamics of fast-moving energetic protons in the magnetosphere. In addition to a quantitative analysis of the prediction results, we also investigate parameter importance in our model. The most decisive parameters for predicting proton intensities are related to the location: ZGSE direction and the radial distance. Among the activity indices, the solar wind dynamic pressure is the most important. The results have a direct practical application, for instance, for assessing the contamination particle background in the X-Ray telescopes for X-ray astronomy orbiting above the radiation belts. To foster reproducible research and to enable the community to build upon our work we publish our complete code, the data, as well as weights of trained models.

The final spacetime is composed by one warped brane with $\mathbb{R}^{(3,1)}\times S^{1}$ topology and a power law warp factor, and one noncompact extra dimension transverse to the brane. By looking at the current experimental bounds, we find a range of parameters in which, if the on-brane dimension has an acceptable size, it does not solve the hierarchy problem. In another example this problem is smoothed by the Brans-Dicke parameter.

description: Based on the properties of uniform nuclear matter at the nuclear saturation density and basic thermodynamic relations, we first re-study the composition of matter on the surface of normal neutron stars and hybrid stars. It is found that the hybrid stars are composed of uniform hadronic matter on the surface rather than heavy nuclei. Then we use the Walceka model and the self-consistent NJL model to describe the equation of state of low-density hadrons and quark matter at high densities respectively, and the P--interpolation method is employed to connect the equation of state at the extreme densities to study hybrid stars. As a result, we find that the obtained hybrid star mass-radius relation and tidal deformability meet the latest astronomical data. More importantly, we find that the hybrid stars we obtained can be self-bound rather than gravitationally bound, which is completely different from previous related studies.

description: Felix Weinberg's teenage years coincided with World War II. He spent much of the war in Nazi concentration camps, starting with Terezin in December 1942, Auschwitz in December 1943 and finally Buchenwald, from which he was liberated on 11 April 1945. He joined Imperial College as a research assistant in 1951 and completed his PhD by 1954. He was appointed to a personal chair as professor of combustion physics in 1967, and he stayed at Imperial for his entire career. Weinberg was distinguished for his optical and electrical studies of flames and his pioneering development of innovative combustion methods. He invented a family of powerful optical tools in combustion, using both broad spectrum and laser light sources. His work on electrical diagnostics led to applications of electric fields to control combustion and to improved understanding of ionization and soot formation. He developed novel combustion devices that incorporated distinctive heat exchangers, thereby permitting the ignition and burning of very low calorific fuel–air mixtures. All of these works had a propelling influence on the global evolution of environmentally benign combustion furnaces. His wide-ranging service to academia, industry and scientific societies included visiting scholar appointments at universities around the world, consultancies for petroleum, chemical, aerospace and defence organisations, and active membership on committees and boards of governance for many scientific and professional bodies. He was author, co-author or editor of four books and well over 200 papers in the scientific literature

description: We show how a single trapped ion may be used to test a variety of important physical models realized as time-dependent harmonic oscillators. The ion itself functions as its own motional detector through laser-induced electronic transitions. Alsing et al. [Phys. Rev. Lett. 94, 220401 (2005)] proposed that an exponentially decaying trap frequency could be used to simulate (thermal) Gibbons-Hawking radiation in an expanding universe, but the Hamiltonian used was incorrect. We apply our general solution to this experimental proposal, correcting the result for a single ion and showing that while the actual spectrum is different from the Gibbons-Hawking case, it nevertheless shares an important experimental signature with this result.

Appropriate technology and the rural energy sector in South East Asian developing countries
Creators: name: Subbakrishna, Nagendra
Publisher: name: University of British Columbia
Year: 2010

description: Given increasing problems in the availability, affordability and deliverability of commercial primary and secondary energy resources, coupled with growing macroeconomic uncertainties, the use of renewable, non-commercial energy resources has been actively promoted in rural areas of developing countries. This, in addition to the fact that conventional, 'state-of-the-art' energy facilities present technical problems, are inequitable and pose potential environmental hazards, has led to proposals for instituting alternative, intermediate or 'appropriate' technologies in rural settlements. This thesis identifies technical, economic, social, cultural and institutional barriers to the introduction of intermediate or 'appropriate' technologies in rural areas. The cases of solar and biogas technologies in Korea, Malaysia, Papua New Guinea the Philippines and Thailand are considered. Policy and planning process recommendations are made on the roles of government, voluntary aid-agencies and the rural user, to overcome the obstacles to implementing these technologies. These recommendations cover the micro (village) and macro (regional and national) levels over two time horizons, and stress the need for a comprehensive approach to discerning rural needs, followed by integrated technology diffusion through effective program and project implementation. In addition, this thesis identifies the need for a continuous collection of information on rural socio-economic conditions and potential for rural interfuel substitution and finally, recommends research into improving technical efficiencies of alternative energy technologies such as solar and biogas. Alternative or intermediate energy technologies such as solar and biogas can play an important role in augmenting rural energy supply. Unless steps are taken to remove the identified barriers to implementation in future technology diffusion efforts, this potential will not be realized. Policy and planning process recommendations made in this thesis present means through which these barriers could be removed.

The structure functions $F^A_2(x,Q^2)$, $x F^A_3(x,Q^2)$ and ratios of differential cross sections are presented where the nuclei $A$ are chosen to be carbon, iron and lead. We propose a kind of universal modification functions which would provide a nontrivial test of SRC universality on the platform of neutrino-nucleus scattering and improve our understanding of nucleon structure substantially.

description: Recent reports on the intriguing features of vector vortex bearing beams are analyzed using geometric phases in optics. It is argued that the spin redirection phase induced circular birefringence is the origin of topological phase singularities arising in the inhomogeneous polarization patterns. A unified picture of recent results is presented based on this proposition. Angular momentum shift within the light beam (OAM) has exact equivalence with the angular momentum holonomy associated with the geometric phase consistent with our conjecture.

Abstract: Growing trend of digitization and ever-decreasing cost of digital VLSI are the driving force for the increasing adoption of digital control in power management commercial products for emerging applications, such as automotive, data center and computing, telecom, aerospace, EV chargers, renewable, etc. Digital control offers fast transient, high efficiency and reliability, reduced conducted EMI, lower component count, fault tolerant and faster time-to-market. However, the challenges remain in identifying cost-effective digital control solutions, modelling, analysis and design methods. This presentation covers opportunities and challenges using digital control, and highlights some commercial digital control ICs and system solutions. Well-known fixed/variable frequency analog control techniques are summarized, and possible levels of digitization are presented for individual control methods by considering cost, flexibility, modularity, etc. Thereafter, fixed and variable frequency digital control architectures are presented. Different modelling and analysis techniques are summarized. Small- and large-signal based design methods are explored by considering simplicity and accuracy aspects. Some popular digital PWM and ripple based digital control techniques are presented, and their benefits and shortcomings are presented. Thereafter, the need for cost-effective IP and skilled manpower development is identified. Finally, the overview of a newly developed online course is presented, which is entitled Digital Control of Switched Mode Power Converter and FPGA-based Prototyping. This will provide pedagogical resources for Power Electronics researchers and engineers, which will be freely accessible on YouTube in November 2022.

Intrinsic and Extrinsic Motivation

description: Economists believe in (monetary) incentives. However, in the specialized area of prosocial behaviours,

(monetary) incentives could backfire because extrinsic motivation might crowd out intrinsic motivation.

Moreover, national differences in the perception of incentives should also be considered, taking

the cultural background of individuals into account. In this project, we ran a real effort experiment in

Germany and in China. In addition to an extrinsic monetary incentive (personal payment) to the subjects,

we made a donation to UNICEF, and the amount of the donation depended on the effort of the

subjects, which served as an intrinsic motivation. The results indicate that with respect to activities

with a prosocial element, Germans tended to exert a high level of effort, regardless of the alternation

of the art and the level of their payoff; in contrast, the Chinese did react to extrinsic monetary incentives

and exerted more effort with a linear payment or if the level of payment was high. Females exerted

significantly more effort than males, and this was true for both the German and Chinese subjects.

The last finding is that the Chinese were more motivated by a fixed non-monetary payment than a

fixed monetary payment, if the level of payment was relatively low.

Spin flip lifetimes in superconducting atom chips: BCS versus Eliashberg theory

description: We investigate theoretically the magnetic spin-flip transitions of neutral atoms trapped near a superconducting slab. Our calculations are based on a quantum-theoretical treatment of electromagnetic radiation near dielectric and metallic bodies. Specific results are given for rubidium atoms near a niobium superconductor. At the low frequencies typical of the atomic transitions, we find that BCS theory greatly overestimates coherence effects, which are much less pronounced when quasiparticle lifetime effects are included through Eliashberg theory. At 4.2 K, the typical atomic spin lifetime is found to be larger than a thousand seconds, even for atom-superconductor distances of one micrometer. This constitutes a large enhancement in comparison with normal metals.

Abstract: Advanced electronic/optoelectronic technologies designed to allow stable, intimate integration with living organisms will accelerate progress in biomedical research; they will also serve as the foundations for new approaches in monitoring and treating diseases. Specifically, capabilities for injecting miniaturized electronic systems and other components into soft tissues or for softly laminating them onto the surfaces of vital organs will open up unique and important opportunities in tracking and manipulating biological processes. This presentation describes the core concepts in materials science, circuit design and manufacturing that underpin these types of technologies, including bioresorbable, or �transient�, devices designed to disappear into the body on timescales matched to natural processes. Examples include skin-like devices for health monitoring and bioelectronic �medicines� for neuroregeneration and temporary cardiac pacing.
An Empirical Proxy for the Second Integral of Motion in Rotating Barred or Tri-axial Potentials

description: We identify an effective proxy for the analytically-unknown second integral of motion (I_2) for rotating barred or tri-axial potentials. Planar orbits of a given energy follow a tight sequence in the space of the time-averaged angular momentum and its amplitude of fluctuation. The sequence monotonically traces the main orbital families in the Poincare map, even in the presence of resonant and chaotic orbits. This behavior allows us to define the "Calibrated Angular Momentum," the average angular momentum normalized by the amplitude of its fluctuation, as a numerical proxy for I_2. It also implies that the amplitude of fluctuation in L_z, previously under-appreciated, contains valuable information. This new proxy allows one to classify orbital families easily and accurately, even for real orbits in N-body simulations of barred galaxies. It is a good diagnostic tool of dynamical systems, and may facilitate the construction of equilibrium models.

Agonistic behaviour in finishing pigs (Sus scrofa) following mixing : its effect on productivity
Creators: name: Tan, Shenton S.L.
Publisher: name: University of British Columbia
Year: 2010

description: The effect of mixing unfamiliar finishing pigs (Sus scrofa) on agonistic behaviour and productivity over a 3 week period was investigated. Nine groups of six pigs were allocated to one of three treatments and eight groups of six pigs to the fourth treatment. In the first treatment (unmixed) littermate groups were moved into a new pen and in the second treatment (3:3 mixed) 3 pigs from one littermate group were mixed with 3 pigs from a second littermate group. The third treatment (Stresnil-treated) was similar to the second treatment but pigs were injected with the tranquilizer Stresnil (azaperone) prior to mixing. In the fourth treatment (5:1 mixed) groups of five pigs were introduced into a pen already occupied by either a single relatively light weight pig or a relatively heavy weight pig. Intense fighting was displayed by the regrouped pigs immediately following mixing, while unmixed and Stresnil-treated pigs generally went to sleep. During feeding periods, initiated aggression was the most common agonistic behaviour exceeding aggressive responses and submissive responses by a factor of up to 14. In mixed groups initiated aggression was significantly higher than in unmixed groups. Administration of Stresnil appeared to disrupt the animals' behavioural repetoire by delaying aggression, retarding social hierarchy establishment and depressing productivity. Prior occupancy of pen space also appeared to influence aggressive behaviour. Over the entire three week sample period, average daily weight gains (ADG) of all three mixed treatments were significantly less than unmixed groups. The differences were significant during the first week but not in the second or third weeks. The mixed groups were also poorer converters of feed during the first week and over the three week period. Stresnil-treated pigs, on average, exhibited the poorest productivity of the mixed treatments. The economic costs of raising mixed groups from an initial weight of 76 kg to a standard final weight of 95 kg as a result of their reduced weight gain and feed efficiency, was substantial: $2.92 per pig for Stresnil-treated groups; $1.43 per pig for 3:3 mixed groups; and $1.13 per pig for 5:1 mixed groups. Assuming that growth rates remain the same, extrapolation of the data to a market weight of 102 kg resulted in overall costs of $3.50 per pig for Stresnil-treated groups, $1.94 per pig for 3:3 mixed groups and $1.54 per pig for 5:1 mixed groups.
