The Nature and Evolution of Far-Infrared Luminous Galaxies
Creators: name: Patel, Harsit
Publisher: name: Imperial College London
Year: 2012

description: This Thesis presents a study of the nature and evolution of far-infrared (FIR) luminous galaxies using sources selected at 70 μm from the Spitzer Wide-area InfraRed Extragalactic (SWIRE) Survey. The SWIRE survey was the largest of the legacy surveys conducted by the Spitzer Space Telescope covering 49 deg² in six fields. The nature of the FIR sources was explored by obtaining spectroscopic follow-up observations of 70 μm sources selected from the SWIRE Lockman Hole (LH) and XMM-LSS fields. The observations were carried out at the William Herschel Telescope (WHT) using the multi-object spectrograph AF2/WYFFOS. The data were first reduced and calibrated using standard IRAF routines and redshifts measured by identifying emission and absorption lines. The data reduction and redshift measurement steps are described in detail. The spectra were then used to determine the optical and IR properties of 70 μm sources by performing emission line diagnostic and modelling the multiwavelength spectral energy distribution (SED) for these objects. The evolution of FIR luminous galaxies is investigated by constructing 70 and 160 μm and total IR (TIR) luminosity functions (LFs) for all 70 and 160 μm sources in SWIRE LH and XMM-LSS with a measured spectroscopic redshift. In this work the evolution of the 70 μm and TIR LFs was investigated to redshift, z = 1.2, and the evolution of the 160 μm LF was computed to z = 0.5. The final work, was carried out by including 70 and 160 μm sources with photometric redshifts and studying the evolution of FIR luminous galaxies to z = 2 and z = 1.5 respectively. The evolution of the TIR LF was also determined using the 70 μm sample to z = 2. The work presented in this Thesis utilises, for the first time, a parametric Bayesian method to study the evolution of IR galaxies.
Robustness of multi-storey steel-composite buildings under column loss : rate-sensitivity and probabilistic framework
Creators: name: Pereira, Miguel Felipe Duque Fonseca
Publisher: name: Imperial College London
Year: 2012

description: As part of the continuing effort undertaken at Imperial College London to develop a unified measure of robustness, the current study addresses several issues which were identified in the past as prospective enhancements to the ductility-centred framework. As robustness evaluates the structural performance against extreme local actions, it should consider within the assessment framework the duration of the accidental event and its repercussion on the structural response. In this context, incorporation of rate-sensitivity is a step forward to a more realistic structural assessment under blast/impact loading. Towards this end, the rate-sensitivity of steel is quantified with the aid of experimental coupon tests. Subsequent studies on rate-sensitivity at the structural level, which similarly include validation by component testing under moderate to high rates, address a knowledge gap on the dynamic over-strength and ductility supply associated with sudden column loss scenarios. Further developments are made to the framework in order to accommodate material rate-sensitivity, where a case study is undertaken which illustrates the diminishing rate effects at higher structural levels. Since local damage resulting from extreme loading does not revolve around a single possible damage scenario, it is important to investigate other local damage scenarios besides the typically considered single column removal. In this context, the feasibility and practicality of scenarios involving the simultaneous loss of multiple columns are considered, with generalisation of the simplified dynamic assessment and development of simplified models based on dominant modes of deformation. As the study of different damage scenarios moves the discussion on robustness towards rational risk assessment, this work aims to demonstrate the adequacy of the ductility-centred framework to the quantification of the failure probability under column loss scenarios. With an illustrative application study, it is established that such risk assessment is not only feasible but may ultimately provide a valuable decision-making tool in the design process of robust structures.
Dust grains and the structure of steady C-type magnetohydrodynamic shock waves in molecular clouds
Creators: name: Wardle, Mark
Publisher: name: arXiv
Year: 1998
Subjects: subject: Astrophysics (astro-ph)

description: I examine the role of dust grains in determining the structure of steady, cold, oblique C-type shocks in dense molecular gas. Gas pressure, the inertia of the charged components, and changes in ionisation are neglected. The grain charge and rate coefficients for electron-neutral and grain-neutral elastic scattering are assumed constant at values appropriate to the shock interior. An MRN size distribution is accounted for by estimating an effective grain abundance and Hall parameter for single-size grains. A one-parameter family of intermediate shocks exists for each shock speed v_s between the intermediate signal speed v_A cos theta and sqrt{2} v_A cot theta, where v_A is the preshock Alfven speed and theta is the angle between the preshock magnetic field and the normal to the shock front. In addition, there is a unique fast shock for each v_s > v_A. If the preshock density n_H is greater than about 10^5 cm^-3 and the preshock magnetic field satisfies B(mG) less than about n_H(10^5 cm^-3) grains are partially decoupled from the magnetic field and the field and velocity components within fast shocks do not lie in the plane containing the preshock field and the shock normal. The resulting shock structure is significantly thinner than in models that do not take this into account. Existing models systematically underestimate the grain-neutral drift speed and the heating rate within the shock front. At densities in excess of 10^8 cm^-3 these effects may be reduced by the nearly-equal abundances of positive and negative grains.

description: In this interview conducted by Henry La Brie III, Paul H. Wyche discusses the logistics and problems in running the National Black News Service (NBNS), which at the time of the interview was three and a half months old. Wyche views the black press as a necessity for educating all people. He explains how he gathered news from correspondents and freelance journalists, as well as the technical aspects of printing and shipping the news to primarily black newspapers across the country. Wyche compares the NBNS to Claude Barnett's operation, the Associated Negro Press (ANP). He looks at how both groups expanded their respective scope to mainstream media.

description: Following is a collection of lecture notes on D-branes, which may be used by the reader as preparation for applications to modern research applications such as: the AdS/CFT and other gauge theory/geometry correspondences, Matrix Theory and stringy non-commutative geometry, etc. In attempting to be reasonably self-contained, the notes start from classical point-particles and develop the subject logically (but selectively) through classical strings, quantisation, D-branes, supergravity, superstrings, string duality, including many detailed applications. Selected focus topics feature D-branes as probes of both spacetime and gauge geometry, highlighting the role of world-volume curvature and gauge couplings, with some non-Abelian cases. Other advanced topics which are discussed are the (presently) novel tools of research such as fractional branes, the enhancon mechanism, D(ielectric)-branes and the emergence of the fuzzy/non-commutative sphere.

description: The recent results attained from a thermodynamically conceived numerical scheme applied on wave propagation in viscoelastic/rheological solids are generalized here, both in the sense that the scheme is extended to four spacetime dimensions and in the aspect of the virtues of a thermodynamical approach. Regarding the scheme, the arrangement of which quantity is represented where in discretized spacetime, including the question of appropriately realizing the boundary conditions, is nontrivial. In parallel, placing the problem in the thermodynamical framework proves to be beneficial in regards to monitoring and controlling numerical artefacts - instability, dissipation error, and dispersion error. This, in addition to the observed preciseness, speed, and resource-friendliness, makes the thermodynamically extended symplectic approach that is presented here advantageous above commercial finite element software solutions.

description: Using virtual reality setups, users can fade out of their surroundings and dive fully into a thrilling and appealing virtual environment. The success of such immersive experiences depends heavily on natural and engaging interactions with the virtual world. As developers tend to focus on intuitive hand controls, other aspects of the broad range of full-body capabilities are easily left vacant. One repeatedly overlooked input modality is the user's gait. Even though users may walk physically to explore the environment, it usually does not matter how they move. However, gait-based interactions, using the variety of information contained in human gait, could offer interesting benefits for immersive experiences. For instance, stealth VR-games could profit from this additional range of interaction fidelity in the form of a sneaking-based input modality. In our work, we explore the potential of sneaking as a playful input modality for virtual environments. Therefore, we discuss possible sneaking-based gameplay mechanisms and develop three technical approaches, including precise foot-tracking and two abstraction levels. Our evaluation reveals the potential of sneaking-based interactions in IVEs, offering unique challenges and thrilling gameplay. For these interactions, precise tracking of individual footsteps is unnecessary, as a more abstract approach focusing on the players' intention offers the same experience while providing better comprehensible feedback. Based on these findings, we discuss the broader potential and individual strengths of our gait-centered interactions.

description: A kitchen assistant needs to operate human-scale objects, such as cabinets and ovens, in unmapped environments with dynamic obstacles. Autonomous interactions in such environments require integrating dexterous manipulation and fluid mobility. While mobile manipulators in different form factors provide an extended workspace, their real-world adoption has been limited. Executing a high-level task for general objects requires a perceptual understanding of the object as well as adaptive whole-body control among dynamic obstacles. In this paper, we propose a two-stage architecture for autonomous interaction with large articulated objects in unknown environments. The first stage, object-centric planner, only focuses on the object to provide an action-conditional sequence of states for manipulation using RGB-D data. The second stage, agent-centric planner, formulates the whole-body motion control as an optimal control problem that ensures safe tracking of the generated plan, even in scenes with moving obstacles. We show that the proposed pipeline can handle complex static and dynamic kitchen settings for both wheel-based and legged mobile manipulators. Compared to other agent-centric planners, our proposed planner achieves a higher success rate and a lower execution time. We also perform hardware tests on a legged mobile manipulator to interact with various articulated objects in a kitchen. For additional material, please check: www.pair.toronto.edu/articulated-mm/.

Study of the kaon contribution to the T2K neutrino beam using neutrino interactions in the Near Detector
Creators: name: Ives, Sarah Joanne
Publisher: name: Imperial College London
Year: 2012

description: T2K is a long-baseline neutrino oscillation experiment. It uses an accelerator- produced neutrino beam, whereby a beam of protons impinges on a nuclear target, producing kaon and pion mesons that decay to neutrinos. The main neutrino detectors are situated at 2.50 off-axis from the centre of the beam. An accurate flux prediction for this off-axis beam is crucial to achieve the sensitivity required for the goals of T2K. External experiments reduce the major flux uncertainty (hadronic interactions in the target), but are inherently independent of the real and variable beamline conditions of T2K. Therefore, in situ measurements are required to validate the flux. This thesis uses data from the T2K near detector (ND280) to validate the ux prediction. The normalisation of K+-originating neutrinos at the ND280 is measured. The K+ beam component is important since K+ daughters dominate the high energy part of the 𝜈μ beam and contribute to the intrinsic 𝜈e contamination. As many aspects of the beam simulation affect this measurement, including the hadron production at the target and the off-axis angle, it is used to validate the entire system. The November 2010 to March 2011 data set is used, corresponding to 7:837 x 1019 protons on target. 𝜈μ charged-current interactions are selected (with 86.3% purity) using the ND280 tracker and binned according to the momentum and angle of the muon candidate. The Monte Carlo (MC) is fitted to the data to extract the normalisations of both K+ and π+ originating neutrinos, bK and bπ respectively. The flux, cross-section and detector systematic errors are considered. The best fit point is at bK = 0:86 and bπ = 0:78, consistent with the nominal MC at the 1σ level. Additionally, results of the first time calibration of the ND280 detector, primarily of the ECal sub-detector, are presented.

description: The massless Dirac fermions and the ease to introduce spatial and magnetic confinement in graphene provide us unprecedented opportunity to explore confined relativistic matter in this condensed-matter system. Here we report the interplay between the confinement induced by external electric fields and magnetic fields of the massless Dirac fermions in graphene. When the magnetic length lB is larger than the characteristic length of the confined electric potential lV, the spatial confinement dominates and a relatively small critical magnetic field splits the spatial-confinement-induced atomic-like shell states by switching on a pi Berry phase of the quasiparticles. When the lB becomes smaller than the lV, the transition from spatial confinement to magnetic confinement occurs and the atomic-like shell states condense into Landau levels (LLs) of the Fock-Darwin states in graphene. Our experiment demonstrates that the spatial confinement dramatically changes the energy spacing between the LLs and generates large electron-hole asymmetry of the energy spacing between the LLs. These results shed light on puzzling observations in previous experiments, which hitherto remained unaddressed.

Extremal Black Holes as Bound States

description: We consider a simple static extremal multi-black hole solution with constituents charged under different $U(1)$ fields. Each of the constituents by itself is an extremal dilatonic black hole of coupling $a=\srt$. For a special case with two electrically and two magnetically charged black holes the multi-black hole solution interpolates between the familiar $a=\sqrt{3},1,\frac{1}{\sqrt{3}}$ and $0$ solutions, depending on how many black holes are placed at infinity. This proves the hypothesis that black holes with the above dilaton couplings arise in string theory as bound states of fundamental $a=\sqrt{3}$ states with zero binding energy. We also generalize the result to states where the action does not admit a single scalar truncation and show that a wide class of dyonic black holes in toroidally compactified string theory can be viewed as bound states of fundamental $a=\srt$ black holes.

description: For a rooted cluster algebra $\mathcal{A}(Q)$ over a valued quiver $Q$, a \emph{symmetric cluster variable} is any cluster variable belonging to a cluster associated with a quiver $σ(Q)$, for some permutation $σ$. The subalgebra of $\mathcal{A}(Q)$ generated by all symmetric cluster variables is called the \emph{symmetric mutation subalgebra} and is denoted by $\mathcal{B}(Q)$. In this paper we identify the class of cluster algebras that satisfy $\mathcal{B}(Q)=\mathcal{A}(Q)$, which contains almost every quiver of finite mutation type. In the process of proving the main theorem, we provide a classification of quivers mutation classes based on their weights. Some properties of symmetric mutation subalgebras are given.

description: Spark plasma sintering (SPS) technique is applied in combination with hydrogen decrepitation process for the recycling of SmCo5 magnets. The SmCo5 magnets for recycling were first decrepitated by hydrogen gas of a pressure of 4 bar for 3 hours to produce decrepitated powder. This powder was then used to prepare isotropic sintered magnets using the SPS technique, by sintering at 800-1000 oC for 1 minute. Full densification of the SPS-ed magnets was possible at a temperature of 1000 oC. The sample sintered at 900 oC showed the best internal coercivity (jHc) of higher than 1500 kA/m with high remanence (Br) value of 0.47 T and energy product (BH(max)) of 43.4 kJ/m3. The properties of the SPS-ed sample sintered at 900 oC were compared with conventionally sintered (CVS-ed) sample prepared by using fresh SmCo5 powder. The results showed the improvement of the magnetic properties of the SPS-ed sample in comparison to the CVS-ed sample at room temperature, and the possibility to use the SPS-ed sample at high temperature of 180 oC, where the sample showed good magnetic properties of jHc of 1502 kA/m, Br of 0.44 T and BH(max) of 36.4 kJ/m3. The microstructure and X-ray diffraction patterns of the SPS-ed and the CVS-ed samples were studied; where the samples showed to basically consist of SmCo5 matrix phase with Sm2Co7 and Sm-oxides.

description: An invertible function is bi-Lipschitz if both the function and its inverse have bounded Lipschitz constants. Nowadays, most Normalizing Flows are bi-Lipschitz by design or by training to limit numerical errors (among other things). In this paper, we discuss the expressivity of bi-Lipschitz Normalizing Flows and identify several target distributions that are difficult to approximate using such models. Then, we characterize the expressivity of bi-Lipschitz Normalizing Flows by giving several lower bounds on the Total Variation distance between these particularly unfavorable distributions and their best possible approximation. Finally, we discuss potential remedies which include using more complex latent distributions.

description: Purpose: To assess the reliability of postural positioning in two different sitting postures (SP), within- and between-days, as well as intra-tester and inter-tester. Methods: Twenty six individuals were facilitated into lordotic (LSP) and neutral (NSP) SP on two different days by four physiotherapists, while kinematic data were collected. Intra-tester and inter-tester reliability were assessed using measures of relative reliability (intra-class correlation coefficients, ICC) and absolute reliability (standard error of measurement-SEM; minimal detectable change; mean difference; limits of agreement). Results: Substantial or almost perfect relative reliability (ICC >0.67), with very good absolute reliability (SEM <2.7°) was found for both intra- and inter-tester (within- and between-day) reliability. However, likely due to methodological variation affecting head angles on Day 2, the reliability of head/neck angles were poor (ICC as low as −0.11, SEM ≤5.71°). Conclusion: This study suggests that postural positioning of asymptomatic individuals into NSP and LSP can be performed with very good reliability for most spinal angles. Therefore, clinicians can have some confidence that positioning in SPs can be done reliably. However, while the degree of error is typically small, the small range of movement occurring at many spinal angles suggests that determining what is a clinically meaningful change in posture is difficult.

description: We give an isomorphism test for graphs of Euler genus $g$ running in time $2^{O(g^4 \log g)}n^{O(1)}$. Our algorithm provides the first explicit upper bound on the dependence on $g$ for an fpt isomorphism test parameterized by the Euler genus of the input graphs. The only previous fpt algorithm runs in time $f(g)n$ for some function $f$ (Kawarabayashi 2015). Actually, our algorithm even works when the input graphs only exclude $K_{3,h}$ as a minor. For such graphs, no fpt isomorphism test was known before.
 The algorithm builds on an elegant combination of simple group-theoretic, combinatorial, and graph-theoretic approaches. In particular, we introduce $(t,k)$-WL-bounded graphs which provide a powerful tool to combine group-theoretic techniques with the standard Weisfeiler-Leman algorithm. This concept may be of independent interest.

Although quantitative analyses are objective, selection of shape parameters is required. Here, we applied a convolutional neural network (CNN) for the classification of volcanic ash. First, we defined four basal particle shapes (blocky, vesicular, elongated, rounded) generated by different eruption mechanisms (e.g., brittle fragmentation), and then trained the CNN using particles composed of only one basal shape. The CNN could recognize the basal shapes with over 90% accuracy. Using the trained network, we classified ash particles composed of multiple basal shapes based on the output of the network, which can be interpreted as a mixing ratio of the four basal shapes. Clustering of samples by the averaged probabilities and the intensity is consistent with the eruption type. The mixing ratio output by the CNN can be used to quantitatively classify complex shapes in nature without categorizing forcibly and without the need for shape parameters, which may lead to a new taxonomy.

description: On a journey, a backpack is a perfect place to store and organize the necessary provisions and tools. Similarly, carrying and managing items is a central part of most digital games, providing significant prospects for the player experience. Even though VR games are gradually becoming more mature, most of them still avoid this essential feature. Some of the reasons for this deficit are the additional requirements and challenges that VR imposes on developers to achieve a compelling user experience. We structure the ample design space of VR inventories by analyzing popular VR games and developing a structural taxonomy. We combine our insights with feedback from game developers to identify the essential building blocks and design choices. Finally, we propose meaningful design implications and demonstrate the practical use of our work in action.
Development and application of a flow system to study shear stress-induced genes in primary endothelial cells

description: Atherosclerosis is a chronic lipid-modulated inflammatory disease, which develops preferentially in arterial regions, where blood flow is disturbed. Shear stress is exerted on the endothelium and it has been shown that the tangential force can influence intracellular signalling cascades, modulating transcriptional activation or repression of mechanosensitive genes. The exact mechanisms of mechanotransduction are not entirely understood, but the shear-dependent transcription factor Kruppel-like factor 2 (KLF2) has been considered as the master switch in shear-controlled endothelial gene expression. Induction of its target genes triggers anti-inflammatory and anti-thrombotic signalling cascades, determining an atheroprotective phenotype. Endothelial KLF4 has also recently been shown to be shear-sensitive and that it can compensate for reduced KLF2 transcripts. Another member of the KLF family, KLF6, is known to be present in the endothelium, but has not been further investigated. This suggests that KLF2 might not be a single master regulator in the process of shear-dependent atheroprotection. Since KLFs have been demonstrated to form circuitries in other tissues, the hypothesis of the present study was that shear stress invokes a KLF2-KLF4-KLF6 network, which regulates the atheroprotective transcriptional program in the endothelium. The work aimed at understanding shear-dependent signalling mechanisms to potentially reveal therapeutic targets. Firstly, a flow device allowing the in vitro exposure of primary porcine aortic endothelial cells (PAECs) to shear stress was designed. Gene expression patterns were examined with the consideration of parameters associated with time, shear stress magnitude and interference with short inhibitory ribonucleic acid (siRNA). These studies were carried out using quantitative polymerase chain reaction (qPCR), genome-wide microarray analysis, protein detection and computational modelling. The findings revealed an oscillatory expression pattern for KLF2 and KLF4 in high shear regimes of 20 dyne/cm2. siRNA-mediated silencing of KLF4 resulted in a significant downregulation of KLF2 and this dependency was shown for the first time. Global genome analysis identified a number of novel shared, but also individual downstream targets, suggesting that the transcription factors have important non-compensatory regulatory functions. In conclusion, this work contributes to the understanding of the individual roles of KLF2 and KLF4 and their functional overlap in the mediation of atheroprotection. Further investigations are required to assess whether KLFs could potentially be useful in preventing atherosclerosis or identifying atherosclerosis treatments.
Exploring High Multiplicity Amplitudes in Quantum Mechanics

description: Calculations of $1\to N$ amplitudes in scalar field theories at very high multiplicities exhibit an extremely rapid growth with the number $N$ of final state particles. This either indicates an end of perturbative behaviour, or possibly even a breakdown of the theory itself. It has recently been proposed that in the Standard Model this could even lead to a solution of the hierarchy problem in the form of a "Higgsplosion". To shed light on this question we consider the quantum mechanical analogue of the scattering amplitude for $N$ particle production in $ϕ^4$ scalar quantum field theory, which corresponds to transitions $\langle N \lvert \hat{x} \rvert 0 \rangle$ in the anharmonic oscillator with quartic coupling $λ$. We use recursion relations to calculate the $\langle N \lvert \hat{x} \rvert 0 \rangle$ amplitudes to high order in perturbation theory. Using this we provide evidence that the amplitude can be written as $\langle N \lvert \hat{x} \rvert 0 \rangle \sim \exp(F(λN)/λ)$ in the limit of large $N$ and $λN$ fixed. We go beyond the leading order and provide a systematic expansion in powers of $1/N$. We then resum the perturbative results and investigate the behaviour of the amplitude in the region where tree-level perturbation theory violates unitarity constraints. The resummed amplitudes are in line with unitarity as well as stronger constraints derived by Bachas. We generalize our result to arbitrary states and powers of local operators $\langle N \lvert \hat{x}^q \rvert M \rangle$ and confirm that, to exponential accuracy, amplitudes in the large $N$ limit are independent of the explicit form of the local operator, i.e. in our case $q$.

description: This mini-review collects theoretical results predicting the creation of matter-wave solitons by the pseudo-spinor system of Gross-Pitaevskii equations (GPEs) with the self-attractive cubic nonlinearity and linear first-order-derivative terms accounting for the spin-orbit coupling (SOC). In one dimension (1D), the so predicted bright solitons are similar to their well-known counterparts supported by the GPE in the absence of SOC. Completely novel results were recently obtained for 2D and 3D systems: SOC suppresses the collapse instability of the multidimensional GPE, creating fully stable 2D ground-state solitons and metastable 3D ones of two types: semi-vortices (SVs), with vorticities m = 1 in one spin component and m = 0 in the other, and mixed modes (MMs), with m = 0 and m = (+/-)1 present in both components. With the Galilean invariance broken by SOC, moving solitons exist up to a certain critical velocity, suffering delocalization above it. The newest result predicts stable 2D "quantum droplets" of the MM type in the presence of the Lee-Huang-Yang corrections to the GPE system, induced by quantum fluctuations around the mean-field states, in the case when the inter-component attraction dominates over the self-repulsion in each component.

description: Driven by the games community, virtual reality setups have lately evolved into affordable and consumer-ready mobile headsets. However, despite these promising improvements, it remains challenging to convey immersive and engaging VR games as players are usually limited to experience the virtual world by vision and hearing only. One prominent example of such open challenges is the disparity between the real surroundings and the virtual environment. As virtual obstacles usually do not have a physical counterpart, players might walk through walls enclosing the level. Thus, past research mainly focussed on multisensory collision feedback to deter players from ignoring obstacles. However, the underlying causative reasons for such unwanted behavior have mostly remained unclear.
 Our work investigates how task types and wall appearances influence the players' incentives to walk through virtual walls. Therefore, we conducted a user study, confronting the participants with different task motivations and walls of varying opacity and realism. Our evaluation reveals that players generally adhere to realistic behavior, as long as the experience feels interesting and diverse. Furthermore, we found that opaque walls excel in deterring subjects from cutting short, whereas different degrees of realism had no significant influence on walking trajectories. Finally, we use collected player feedback to discuss individual reasons for the observed behavior.

description: Systems that can find correspondences between multiple modalities, such as between speech and images, have great potential to solve different recognition and data analysis tasks in an unsupervised manner. This work studies multimodal learning in the context of visually grounded speech (VGS) models, and focuses on their recently demonstrated capability to extract spatiotemporal alignments between spoken words and the corresponding visual objects without ever been explicitly trained for object localization or word recognition. As the main contributions, we formalize the alignment problem in terms of an audiovisual alignment tensor that is based on earlier VGS work, introduce systematic metrics for evaluating model performance in aligning visual objects and spoken words, and propose a new VGS model variant for the alignment task utilizing cross-modal attention layer. We test our model and a previously proposed model in the alignment task using SPEECH-COCO captions coupled with MSCOCO images. We compare the alignment performance using our proposed evaluation metrics to the semantic retrieval task commonly used to evaluate VGS models. We show that cross-modal attention layer not only helps the model to achieve higher semantic cross-modal retrieval performance, but also leads to substantial improvements in the alignment performance between image object and spoken words.
