description: The goal of this work is to train discriminative cross-modal embeddings without access to manually annotated data. Recent advances in self-supervised learning have shown that effective representations can be learnt from natural cross-modal synchrony. We build on earlier work to train embeddings that are more discriminative for uni-modal downstream tasks. To this end, we propose a novel training strategy that not only optimises metrics across modalities, but also enforces intra-class feature separation within each of the modalities. The effectiveness of the method is demonstrated on two downstream tasks: lip reading using the features trained on audio-visual synchronisation, and speaker recognition using the features trained for cross-modal biometric matching. The proposed method outperforms state-of-the-art self-supervised baselines by a signficant margin.

description: Brane inflation in superstring theory predicts that cosmic strings (but not domain walls or monopoles) are produced towards the end of the inflationary epoch. Here, we discuss the production, the spectrum and the evolution of such cosmic strings, properties that differentiate them from those coming from an abelian Higgs model. As D-branes in extra dimensions, some type of cosmic strings will dissolve rapidly in spacetime, while the stable ones appear with a spectrum of cosmic string tensions. Moreover, the presence of the extra dimensions reduces the interaction rate of the cosmic strings in some scenarios, resulting in an order of magnitude enhancement of the number/energy density of the cosmic string network when compared to the field theory case.

description: Recent observations of the fields surrounding a few Milky-Way-like galaxies in the local Universe have become deep enough to enable investigations of the predictions of the standard LCDM cosmological model down to small scales outside the Local Group. Motivated by an observed correlation between the number of dwarf satellites (N_sat) and the bulge-to-total baryonic mass ratios (B/T) of the three main galaxies in the Local Group, i.e. the Milky Way, Andromeda, and Triangulum (M33), we use published data of three well-studied galaxies outside the Local Group, namely M81, Centaurus A, and M101, and their confirmed satellites, and we find a strong and significant correlation between N_sat and B/T. This presents itself in contradiction with the hitherto published results from cosmological simulations reporting an absence of a correlation between N_sat and B/T in the LCDM model. We conclude that, based on the current data, the N_sat vs. B/T correlation is no longer a property confined to only the Local Group.

description: We consider the problem of an atomic beam propagating quantum mechanically through an atom beam splitter. Casting the problem in an adiabatic representation (in the spirit of the Born-Oppenheimer approximation in molecular physics) sheds light on explicit effects due to non-adiabatic passage of the atoms through the splitter region. We are thus able to probe the fully three dimensional structure of the beam splitter, gathering quantitative information about mode-mixing, splitting ratios,and reflection and transmission probabilities.

description: For predicting software defects at an early stage, researchers have proposed just-in-time defect prediction (JIT-DP) to identify potential defects in code commits. The prevailing approaches train models to represent code changes in history commits and utilize the learned representations to predict the presence of defects in the latest commit. However, existing models merely learn editions in source code, without considering the natural language intentions behind the changes. This limitation hinders their ability to capture deeper semantics. To address this, we introduce a novel bi-modal change pre-training model called BiCC-BERT. BiCC-BERT is pre-trained on a code change corpus to learn bi-modal semantic representations. To incorporate commit messages from the corpus, we design a novel pre-training objective called Replaced Message Identification (RMI), which learns the semantic association between commit messages and code changes. Subsequently, we integrate BiCC-BERT into JIT-DP and propose a new defect prediction approach -- JIT-BiCC. By leveraging the bi-modal representations from BiCC-BERT, JIT-BiCC captures more profound change semantics. We train JIT-BiCC using 27,391 code changes and compare its performance with 8 state-of-the-art JIT-DP approaches. The results demonstrate that JIT-BiCC outperforms all baselines, achieving a 10.8% improvement in F1-score. This highlights its effectiveness in learning the bi-modal semantics for JIT-DP.

Five-loop epsilon expansion for U(n)xU(m) models: finite-temperature phase transition in light QCD

description: We consider the U(n)xU(m) symmetric Phi^4 Lagrangian to describe the finite-temperature phase transition in QCD in the limit of vanishing quark masses with n=m=N_f flavors and unbroken anomaly at T_c. We compute the Renormalization Group functions to five-loop order in Minimal Subtraction scheme. Such higher order functions allow to describe accurately the three-dimensional fixed-point structure in the plane (n,m), and to reconstruct the line n^+(m,d) which limits the region of second-order phase transitions by an expansion in epsilon=4-d. We always find n^+(m,3)>m, thus no three-dimensional stable fixed point exists for $n=m$ and the finite temperature transition in light QCD should be first-order. This result is confirmed by the pseudo-epsilon analysis of massive six-loop three dimensional series.

description: The present paper concerns a space-time homogenization problem for nonlinear diffusion equations with periodically oscillating (in space and time) coefficients. Main results consist of corrector results (i.e., strong convergences of solutions with corrector terms) for gradients, diffusion fluxes and time-derivatives without assumptions for smoothness of coefficients. Proofs of the main results are based on the space-time version of the unfolding method, which is deeply concerned with the strong two-scale convergence theory.

description: Deriving the metallicity, [Fe/H], in low-resolution spectra of carbon-enhanced metal-poor (CEMP) stars is a tedious task that, owing to the large number of line blends, often leads to uncertainties on [Fe/H] exceeding 0.25dex. The CEMP stars increase in number with decreasing [Fe/H] and some of these are known to be bona fide second generation halo stars. Hence, knowing their [Fe/H] is important for tracing the formation and chemical evolution of the Galaxy. Here, we aim to improve the [Fe/H] measurements in low-resolution spectra by avoiding issues related to blends. We improve our chemical tagging in such spectra at low metallicities. We developed an empirical way of deriving [Fe/H] in CEMP (and C-normal) stars that relates the equivalent width (EW) of strong lines, which remain detectable in lower-resolution, metal-poor spectra. The best [Fe/H] tracers are found to be Cr I and Ni I, which both show strong transitions in spectral regions that are free of molecular bands (between ~5200-6800A, a region accessible to most surveys). We derive different relations for dwarfs and giants. The relations are valid in the ranges ~-3-3.2 and EW>5mA (Ni), depending on the element and line as well as the stellar evolutionary stage. The empirical relations are valid for both CEMP and C-normal stars and have been proven to be accurate tracers in a sample of ~400 stars (mainly giants). The metallicities are accurate to within ~0.2 depending on the sample and resolution, and the empirical relations are robust to within 0.05-0.1dex. Our relations will improve the metallicity determination in future surveys, which will encounter a large number of CEMP stars, and will greatly speed up the process of determining [Fe/H] as the EWs only need to be measured in two or three lines in relatively clean regions compared to dealing with numerous blended Fe lines.

description: We have studied the current magnification effect in a multi-channel open mesoscopic ring. We show that the current magnification effect is robust even in the presence of several propagating modes inspite of mode mixing and cancellation effects. The magnitude of circulating currents in the multi-channel regime can be much larger than that in a single channel case. Impurities can enhance or degrade the current magnification effect depending sensitively on the system parameters. Circulating currents are mostly associated with Fano resonances in the total transport current. We further show that system-lead coupling qualitatively changes the current magnification effect.

description: Stock return predictability is an important research theme as it reflects our economic and social organization, and significant efforts are made to explain the dynamism therein. Statistics of strong explanative power, called "factor" have been proposed to summarize the essence of predictive stock returns. Although machine learning methods are increasingly popular in stock return prediction, an inference of the stock returns is highly elusive, and still most investors, if partly, rely on their intuition to build a better decision making. The challenge here is to make an investment strategy that is consistent over a reasonably long period, with the minimum human decision on the entire process. To this end, we propose a new stock return prediction framework that we call Ranked Information Coefficient Neural Network (RIC-NN). RIC-NN is a deep learning approach and includes the following three novel ideas: (1) nonlinear multi-factor approach, (2) stopping criteria with ranked information coefficient (rank IC), and (3) deep transfer learning among multiple regions. Experimental comparison with the stocks in the Morgan Stanley Capital International (MSCI) indices shows that RIC-NN outperforms not only off-the-shelf machine learning methods but also the average return of major equity investment funds in the last fourteen years.

description: We present a random-interface representation of the three-dimensional (3D) Ising model based on thermal fluctuations of a uniquely defined geometric spin cluster in the 3D model and its 2D cross section. Extensive simulations have been carried out to measure the global interfacial width as a function of temperature for different lattice sizes which is shown to signal the criticality of the model at $T_c$ by forming a size-independent cusp in 3D, along with an emergent super-roughening at its 2D cross section. We find that the super-rough state is accompanied by an intrinsic anomalous scaling behavior in the local properties characterized by a set of geometric exponents which are the same as those for a pure 2D Ising model.

title: Fall and Rise of the Tarentaise Zone, Western Alps
Creators: name: Lomas, Simon
Publisher: name: The Open University
Year: 1993

description: The Tarentaise Zone is an intensely deformed thrust-bounded meta-sedimentary package which represents a poorly understood belt of late Cretaceous subsidence on the northern passive continental margin of the Tethyan ocean. This contribution presents new field data which place tighter constraints on models of basin evolution. Structurally, the Tarentaise units have been stripped from their basement and imbricated to form a WNW-verging fold-thrust stack with complex internal strains. Demonstration that tectonic displacements were uniquely foreland-directed allows a preliminary qualitative reconstruction of basin architecture and hence provides a framework for stratigraphie analysis. The major sequence boundary recording the onset of late Cretaceous subsidence of the Tarentaise Basin is a subaerial erosion surface which truncates Jurassic rift structures of the precursory continental margin. This unconformity is directly overlain by sub- wave-base clastic sediments without any intervening shallow marine facies, indicating that subsidence occurred rapidly relative to sedimentation. The early basin-fill sediments are dominated by coarse, immature mass-flow conglomerates, deposited on a deep water fan-delta adjacent to a rapidly eroding area of high relief. Syn-extensional tholeiitic magmatism (the so-called Versoyen 'ophiolite') is consistent with intense localised crustal stretching: geochemical analyses of these metabasites revealing evidence of hydrothermal alteration but preservation of MORB-like trace element ratios. The implication of active subsidence contradicts those models for the development of the north Tethyan continental margin which predict strong attenuation and deep submergence by the end of the initial subsidence episode: the Tarentaise segment of the passive margin must have been capable both of being elevated above sea level and of being subsequently rifted a second time.

The effects of mechanical stretch on the immunological and anti-inflammatory properties of skeletal muscle cells: An in vitro study of potential mechanisms that affect response to exercise therapy
Creators: name: Aldosari, Ziyad M.
Publisher: name: University of Leicester
Year: 2020

description: The contraction of skeletal muscle during exercise that occurs in the absence of muscle damage has been demonstrated to yield a significant increase in the release of potentially anti-inflammatory myokine interleukin-6 (IL-6). Increased generation of IL-6 may be valuable in managing inflammatory states, such as chronic kidney disease (CKD). However, the IL-6 output of CKD patients during muscular exercise may be unusually weak, due to factors such as metabolic acidosis.In CKD, physical exertion has been reported to lower levels of amino acids in muscles in vivo. This effect may be attributable to uraemic metabolic acidosis and exercise-induced acidosis impairing mitogen-activated protein kinases (MAPKs) such as p38, which normally activate the amino acid transporter SNAT2. The SNAT2 transporter protein is also known to be directly and rapidly inhibited by low pH. The resulting intracellular amino acid depletion could, in turn, result in inhibited protein synthesis, and hence reduced production of IL-6.This study sought to test the following hypotheses: (1) higher levels of IL-6 expression occur in mechanically stressed skeletal muscle cells following in vitro mechanical stretch, arising from the activation of MAPKs, followed by activation of SNAT2; and (2) low pH blocks this process.Experiments on L6 rat skeletal muscle cells showed that drug inhibition of MAPKs inhibited SNAT2 transport activity, confirming that MAPKs play a role in the regulation of SNAT2 and, by extension, in the availability of amino acids for protein synthesis.Interestingly, while P-p38 and P-JNK activation significantly increased after cyclic stretching of 1-10 minutes duration, SNAT2 activity significantly increased only transiently i.e. after periods of stretching lasting 1 minute, suggesting that this transporter may paradoxically be inhibited by prolonged stretching. In addition, mRNA of IL-6 was increased after 30 minutes of intermittent stretching and, (as previously reported elsewhere) by 6 hours of Ca2+ loading of the cells with ionomycin which activates p38.The siRNA silencing of SNAT2 in L6 myoblasts decreased gene expression of the mRNA of IL-6, suggesting that SNAT2 can influence IL-6 expression. As SNAT2 and MAPKs, particularly p38 and JNK, are inhibited at low pH, it would be predicted that low pH (pH 7.1) would decrease IL-6 expression. However, both with and without ionomycin, low pH failed to decrease IL-6 mRNA; indeed with ionomycin low pH strongly activated IL-6 expression.It is concluded that even though the acidosis-sensing amino acid transporter SNAT2 may play some role in regulating IL-6 expression (as previously hypothesised), a distinct and novel stimulatory effect of low pH over-rides this and maybe a more important regulator of IL-6 expression in L6 skeletal muscle cells.
Integrating housing and transportation policy in BC: implications for immigrant communities
Creators: name: Thomas, Ren
Publisher: name: The University of British Columbia
Year: 2011

description: Canadian municipalities have become increasingly concerned with growth management, including the designation of areas for new housing, new transportation infrastructure, and increased density along transit corridors. Municipal and regional growth policies often combine housing and transportation growth into specifi c areas or initiatives, such as transit-oriented development. As immigration is a major component of population growth in our cities, immigrants’ housing and transportation patterns are of particular importance in the development of growth management policy. Does immigration impact growth management policy? How might these policies affect immigrants’ housing and transportation choices in terms of affordability and transit-accessibility? This paper focuses on six British Columbia cities: Vancouver, Surrrey, Richmond, Kelowna, Kamloops, and Victoria. It reviews their Offi cial Community Plan documents and supporting housing policy and transportation plan documents. The goal is to compare and discuss growth management policies, with a particular emphasis on the links between housing and transportation policy. The implications for immigrants in these six cities will then be discussed. This paper was prepared for the Symposium on Challenges to Affordability and Sustainable Housing at the School of Community and Regional Planning on October 16, 2009.

As a result of Bradford Method, the highest amount of soluble protein was found in Portabella Mushroom (2.21 mg/ml) followed with Button mushroom (1.25 mg/ml), King oyster mushroom (1.15 mg/ml) and least amount of protein was found in Shimeji mushroom (0.53 mg/ml). Based on Lowry’s Method of soluble protein estimation, the highest amount of protein was found in Button mushroom (2.35 mg/ml) followed with King oyster mushroom (2.24 mg/ml), Portabella Mushroom (2.07 mg/ml) and least amount of protein was found in Oyster mushroom (1.20 mg/ml). The phytochemical analysis revealed that the extracts were rich sources of phytoconstituents containing Cardiac glycosides, Terpenoids, Proteins, Saponins and Lignin. Crude proteins of six mushroom samples were extracted, purified and separated on 12% polyacrylamide gel and clear distinct bands were observed with Coomassie Brilliant Blue staining. Banding patterns were varied from sample to sample ranging from 5 to 20 bands and different sizes from 10 kDa to 170 kDa. Protein and phytochemical rich mushrooms can serve as food and medicine.

description: Playing a symmetric bi-matrix game is usually physically implemented by sharing pairs of 'objects' between two players. A new setting is proposed that explicitly shows effects of quantum correlations between the pairs on the structure of payoff relations and the 'solutions' of the game. The setting allows a re-expression of the game such that the players play the classical game when their moves are performed on pairs of objects having correlations that satisfy the Bell's inequalities. If players receive pairs having quantum correlations the resulting game cannot be considered another classical symmetric bi-matrix game. Also the Nash equilibria of the game are found to be decided by the nature of the correlations.

description: The Thirty Meter Telescope will use a sophisticated adaptive optics system called NFIRAOS. This system utilizes two deformable mirrors conjugate to 0 km and 11.2 km to apply a Multi-Conjugate Adaptive Optics (MCAO) correction over a 2 arcminute field of view. DM0 and DM11 have 63 and 75 actuators across their respective diameters. To study the behavior of these mirrors, we have developed a low-cost, very high-order Shack-Hartmann Wavefront Sensor (WFS). We will use our WFS to calibrate the flatness of the DMs and measure the influence functions of the actuators. NFIRAOS is cooled to reduce the thermal emissivity of optical surfaces visible to the science detectors, so we will also measure the behaviour of the DMs in both warm and cold environments. As the cold chamber is prone to vibrations, a WFS is preferred to a phase-shifting interferometer. Our design was driven by the need to be able to evaluate the DM surface between the actuators, which led to the requirement of at least 248 sub apertures across the diameter. The largest commercially available Shack-Hartmann WFS has only 128 sub-apertures across the diameter, which is not enough to properly sample these DMs. Furthermore, the designed sensor is able to record the wavefront at 50 FPS (50 times per second) at full resolution. To fabricate this WFS, we used a commercial off-the-shelf CMOS detector, camera lens, and lens let array, which kept the total cost less than 20K USD. Here we present the design and performance characteristics of this device.
title: Using SAR Data for Mapping Deforestation and Forest Degradation
Creators: name: Kellndorfer, Josef
Publisher: name: NASA
Year: 2019

description: This chapter focuses on Synthetic Aperture Radar (SAR) observations of forest cover change from deforestation and forest degradation. Discussed are SAR backscatter changes determined by sensor and target parameters. Sensor parameters include the wavelength/frequency of the SAR, as well as incidence angle, look directions, and transmit and receive polarization. Since sensor parameters are typically stable from a satellite SAR, backscatter variations over time can be attributed to two main target parameters: structure and moisture. For forests and other targets, this means observations of backscatter change can be linked directly to change in forest structure and moisture conditions of the vegetation and underlying soil.

description: The fluctuating Gunn-Peterson approximation (FGPA) is a commonly-used method to generate mock Lyman-$α$ (Ly$α$) forest absorption skewers at Cosmic Noon ($z\gtrsim 2$) from the matter-density field of $N$-body simulations without running expensive hydrodynamical simulations. Motivated by recent developments in 3D IGM tomography observations as well as matter density field reconstruction techniques applied to galaxy redshift samples at $z\sim 2$, we examine the possibility of observationally testing FGPA by directly examining the relationship between the Ly$α$ transmission and the underlying matter density field. Specifically, we analyze the EAGLE, Illustris, IllustrisTNG and Nyx cosmological hydrodynamic simulations, that were run with different codes and sub-grid models. While the FGPA is an excellent description of the IGM in lower-density regions, the slope of the transmission-density distribution at higher densities is significantly affected by feedback processes causing the FGPA to break down in that regime. Even without added feedback, we find significant deviations caused by hydrodynamical effects arising from non-linear structure growth. We then proceed to make comparisons using realistic mock data assuming the sightline sampling and spectral properties of the recent CLAMATO survey, and find that it would be challenging to discern between the FGPA and hydrodynamical models with current data sets. However, the improved sightline sampling from future extremely large telescopes or large volumes from multiplexed spectroscopic surveys such as Subaru PFS should allow for stringent tests of the FGPA, and make it possible to detect the effect of galaxy feedback on the IGM.

Year: 1993

description: This thesis describes attempts to synthesise phosphoryl carbon mustards (bischloroethylphosphonates). Several strategies were employed based on phosphorus-carbon or carbon-carbon bond disconnections. Thus routes involving the reaction between: (i) phosphites, nucleophilic phosphorus reagents, and haloalkanes or ketones; (ii) dialkyl chlorophosphates, as electrophilic phosphorus reagents, and carbon nucleophiles; and (iii) nucleophilic dialkyl alkanephosphonate anions and carbon electrophiles are described. Thus far none of these routes yielded the desired compounds and some reasons for this are discussed.

description: A novel fractal dual-mode microstrip bandpass filter design has been introduced in an attempt to produce filters with highly miniaturized size for modern wireless applications. The filter structure has been generated based on the 3 rd iteration Minkowski-like pre-fractal geometry, using the conventional dual-mode square ring resonator as the initiator in the fractal generation process. The space-filling property, self-similarity and the diagonal symmetry of the structures corresponding to the successive iteration levels of this fractal geometry have found to produce reduced size filter structures with accepted performance. The bandpass filter structure produced by the 3 rd iteration of this fractal geometry can be considered as a novel design with adequate performance. This design structure possesses a size reduction of about 72% compared with the conventional dual-mode square ring resonator operating at the same frequency and using the same substrate material. In addition, the new design technique seems reliable, since it provides the filter designers with more degree of freedom and further size reduction as compared with those reported in the literature.

description: Most farm management decisions are made under conditions of risk. Risk in agriculture arises from market forces, weather, disease, insect damage, and other factors which cannot be controlled or accurately predicted. One of the major goals of farm commodity programs is to reduce instability in both prices and supplies. With increased stability, producers can make more realistic business plans. Current commodity programs contain price supports in the form of loans and target prices as well as set-aside and diversion provisions. While these provisions are designed to reduce instability, they represent additional variables the farmer must consider in his planning process. The objective of this paper is to present a model that can be used to examine the price risk reducing effects of government programs on farm organization for alternative farm tenure situations. Many models used to study farm management problems are specified under assumed certainty. For example, conventional linear programming does not really accommodate risk. Of course, assumed yields and prices can be changed in these models to analyze their effects on farm organization, but there is no measurement of the risk associated with each resulting farm organization. As a result, conventional linear programming solutions of farm organizations have often been rejected because the solutions may specify actions that lead to a higher degree of risk than many farm managers are willing to accept

description: We provide a complete solution of closed strings propagating in Nappi-Witten space. Based on the analysis of geodesics we construct the coherent wavefunctions which approximate as closely as possible the classical trajectories. We then present a new free field realization of the current algebra using the gamma, beta ghost system. Finally we construct the quantum vertex operators, for the tachyon, by representing the wavefunctions in terms of the free fields. This allows us to compute the three- and four-point amplitudes, and propose the general result for N-point tachyon scattering amplitude.

title: Power to all or few People? An Exploration of Power Dynamics in Holocrazy

description: Power is key to all organizing. It allows actors to perform actions, make decisions and assign tasks to others. In bureaucratic organizations power is mainly associated with the position that the actor holds. Because actors compete for power, change their position within an organization or leave an organization, power is dynamically changing. We refer to these changes in power as power dynamics. Many New Forms of Organizing, such as Holacracy, claim that individuals have more decision-making capacity, i.e., that power is more equally distributed within the organization. In this paper, we use a unique dataset from a holacratic organization to empirically examine how power dynamics in Holacracy evolve over time. In particular, we use temporal network analysis to reconstruct and contrast two related networks that capture information on how decisions in Holacracy are made. Our findings indicate that also in Holacracy power is not equally distributed, but that few individuals hold most power.
