description: Egocentric activity recognition in first-person videos has an increasing importance with a variety of applications such as lifelogging, summarization, assisted-living and activity tracking. Existing methods for this task are based on interpretation of various sensor information using pre-determined weights for each feature. In this work, we propose a new framework for egocentric activity recognition problem based on combining audio-visual features with multi-kernel learning (MKL) and multi-kernel boosting (MKBoost). For that purpose, firstly grid optical-flow, virtual-inertia feature, log-covariance, cuboid are extracted from the video. The audio signal is characterized using a "supervector", obtained based on Gaussian mixture modelling of frame-level features, followed by a maximum a-posteriori adaptation. Then, the extracted multi-modal features are adaptively fused by MKL classifiers in which both the feature and kernel selection/weighing and recognition tasks are performed together. The proposed framework was evaluated on a number of egocentric datasets. The results showed that using multi-modal features with MKL outperforms the existing methods.
On the Foundation of the Relativistic Dynamics with the Tachyon

description: The theoretical foundation of the object moving faster than light in vacuum ({\it tachyon}) is still missing or incomplete. Here we present the classical foundation of the relativistic dynamics including the tachyon. An anomalous sign-factor extracted from the transformation of ${ \sqrt{1-u^{2}/c^{2} } }$ under the Lorentz transformation, which has been always missed in the usual formulation of the tachyon, has a crucial role in the dynamics of the tachyon. Due to this factor the mass of the tachyon transforms in the unusual way although the energy and momentum, which are defined as the conserved quantities in all uniformly moving systems, transform in the usual way as in the case of the object moving slower than light ({\it bradyon}). We show that this result can be also obtained from the least action approach. On the other hand, we show that the ambiguities for the description of the dynamics for the object moving with the velocity of light ({\it luxon}) can be consistently removed only by introducing a new dynamical variable. Furthermore, by using the fundamental definition of the momentum and energy we show that the zero-point energy for any kind of the objects, {\it i.e.}, the tachyon, bradyon, and luxon, which has been known as the undetermined constant, should satisfy some constraints for consistency, and we note that this is essentially another novel relativistic effect. Finally, we remark about the several unsolved problems.

Anisotropic magnetohydrodynamic turbulence driven by parametric decay instability: the onset of phase mixing and Alfvén wave turbulence

Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)

description: We conduct a three-dimensional magnetohydrodynamic (MHD) simulation of the parametric decay instability of Alfvén waves and resultant compressible MHD turbulence, which is likely to develop in the solar wind acceleration region. Because of the presence of the mean magnetic field, the nonlinear stage is characterized by filament-like structuring and anisotropic cascading. By calculating the timescales of phase mixing and the evolution of Alfvén wave turbulence, we have found that the early nonlinear stage is dominated by phase mixing, while the later phase is dominated by imbalanced Alfvén wave turbulence. Our results indicate that the regions in the solar atmosphere with large density fluctuation, such as the coronal bottom and wind acceleration region, are heated by phase-mixed Alfvén waves, while the other regions are heated by Alfvén wave turbulence.

The causes of insect endemicity with the example of Madagascar
Creators: name: Isambert, Benjamin
Publisher: name: Imperial College London
Year: 2010

description: Abstract Biodiversity is disappearing at an exceptional rate, engendering a considerable effort of the scientific community to conserve the rarest and most threatened species. Biodiversity Hotspots were designed for this purpose and Madagascar, showing the highest levels of endemism and imbalance across taxa, rapidly became their flagship. The processes that lead to such exceptional biodiversity patterns on the island remain poorly understood and the lack of efficacy of traditional taxonomy to catalogue tropical endemic biodiversity hinders the scientific advances in this domain. This study tackles insect endemism in Madagascar, aiming at identifying the evolutionary and ecological factors responsible for their present diversity patterns. Aquatic beetles, living in standing or running water, submit to differences in habitat stability, potentially affecting dispersal patterns and hence endemism patterns. We chose them as a target group for these reasons, and first achieved a DNA level inventory of the fauna. We identified 169 species, showing high congruence with the morphological taxonomy and corresponding to 74% of the total estimated species richness. The mitochondrial dataset revealed high spatial turnover at the species and haplotype levels. A phylogenetic tree from three gene markers was used for ancestral state character reconstruction and suggested the dependent evolution of endemism and habitat use. Secondly, our results highlight a combination of low dispersal activity and important climatic constraints for the lotic fauna, explaining the local scale endemism in this group, whereas the lentic species turnover correlated the least to both climate and geographic distance. Last, a distribution modelling approach revealed the uniqueness of Malagasy climate niches and the absence of conservation of environmental envelopes at higher phylogenetic levels. We conclude that endemism in Madagascar is best explained locally by the dependence to environmental variability of the lotic species, and that dispersal capacities are the primary hindrance to colonising external suitable habitats.

description: Machine learning models have led to remarkable progress in visual recognition. A key driving factor for this progress is the abundance of labeled data. Over the years, researchers have spent a lot of effort curating visual data and carefully labeling it. However, moving forward, it seems impossible to annotate the vast amounts of visual data with everything that we care about. This reliance on exhaustive labeling is a key limitation in the rapid deployment of computer vision
systems in the real world. Our current systems also scale poorly to the large number of concepts and are passively spoon-fed supervision and data. In this thesis, we explore methods that enable visual learning without exhaustive supervision. Our core idea is to model the natural regularity and repetition in the visual world in our learning algorithms as their inductive bias. We observe recurring patterns in the visual world - a person always lifts their foot before taking a step, dogs are similar to other furry creatures than to furniture etc. This natural regularity in visual data also imposes regularities on the semantic tasks and models
that operate on it - a dog classifier must be similar to classifiers of furry animals than to furniture classifiers. We exploit this abundant natural structure or ‘supervision’ in the visual world in the form of self-supervision for our models, modeling relationships between tasks and labels, and
modeling relationships in the space of classifiers. We show the effectiveness of these methods on both static images and videos across varied tasks such as image classification, object detection, action recognition, human pose estimation etc. However, all these methods are still passively fed
supervision and thus lack agency: the ability to decide what information they need and how to get it. To this end, we propose having an interactive learners that ask for supervision when needed and can also decide what samples they want to learn from.

description: The exchange-correlation energy in Kohn-Sham density functional theory is expressed as a functional of the electronic density and the Kohn-Sham orbitals. An alternative to Kohn-Sham theory is to express the energy as a functional of the reduced first-order density matrix or equivalently the natural orbitals. In the former approach the unknown part of the functional contains both a kinetic and a potential contribution whereas in the latter approach it contains only a potential energy and consequently has simpler scaling properties. We present an approximate, simple and parameter-free functional of the natural orbitals, based solely on scaling arguments and the near satisfaction of a sum rule. Our tests on atoms show that it yields on average more accurate energies and charge densities than the Hartree Fock method, the local density approximation and the generalized gradient approximations.
Development of a Phosphoproteomic Screen of Innate Immune Signalling: Identification and Characterisation of a Novel Phosphorylation of NFkB1/p105
Creators: name: Reder, Gabor
Publisher: name: Imperial College London
Year: 2010

description: Toll-like receptors (TLRs) expressed by antigen-presenting cells of the innate immune system, such as macrophages, detect microbial products and activate signalling cascades that initiate specific gene expression programmes that define the subsequent adaptive immune response. However, it is poorly understood how TLR-specific responses arise, as many of the signalling components are common to multiple TLRs, and it is likely that as yet undiscovered phosphorylations of signalling proteins contribute to specificity of TLR pathways. TLR4, the receptor for lipopolysaccharide (LPS), is used as a model system for TLR signalling, as it activates many of the signalling mechanisms utilised by other TLRs, and I attempted to discover novel regulatory phosphorylations in LPS-activated RAW 264.7 macrophages. Because it is not yet possible to accurately predict post-translational modifications from genomic data, the exact sites of phosphorylation have to be identified experimentally, and the method of choice for this is mass spectrometry-based phosphoproteomics. Using an optimised phosphoproteomics workflow and stringent filtering criteria, I identified 445 phosphorylation sites in unstimulated and LPS-treated RAW macrophages, several of which were potential LPS-induced regulatory phosphorylations, including a previously uncharacterised phosphorylation of the NF-κB protein p105, a key regulator of TLR and other inflammatory signalling pathways. Following validation of a phospho-specific p105 antibody, I demonstrated that the novel phosphorylation of p105 was induced by LPS, other TLR ligands, tumour necrosis factor (TNF)-α, and prostaglandin E2 in RAW macrophages and primary human macrophages, and by interleukin (IL)-1β in 4 primary human skin fibroblasts. Moreover, the LPS-induced phosphorylation of p105 was blocked by the protein kinase A (PKA) inhibitor H89. These results indicate that the novel phosphorylation of p105 may be important for the regulation of TLR and other inflammatory signalling pathways in both hemopoietic and non-hemopoietic cells.

description: A physical unclonable function (PUF) generates hardware intrinsic volatile secrets by exploiting uncontrollable manufacturing randomness. Although PUFs provide the potential for lightweight and secure authentication for increasing numbers of low-end Internet of Things devices, practical and secure mechanisms remain elusive. We aim to explore simulatable PUFs (SimPUFs) that are physically unclonable but efficiently modeled mathematically through privileged one-time PUF access to address the above problem. Given a challenge, a securely stored SimPUF in possession of a trusted server computes the corresponding response and its bit-specific reliability. Consequently, naturally noisy PUF responses generated by a resource limited prover can be immediately processed by a one-way function (OWF) and transmitted to the server, because the resourceful server can exploit the SimPUF to perform a trial-and-error search over likely error patterns to recover the noisy response to authenticate the prover. Security of trial-and-error reverse (TREVERSE) authentication under the random oracle model is guaranteed by the hardness of inverting the OWF. We formally evaluate the TREVERSE authentication capability with two SimPUFs experimentally derived from popular silicon PUFs.

description: Archaeological excavations at El Dumpe and the Embankment site were conducted by Desert Archaeology, Inc. in the summer of 1994. The Arizona Department of Transportation had made plans to install frontage roads on each side of Interstate 10, between Speedway Boulevard and Grant Road. Archaeological testing had previously suggested these sites might be National Register eligible. Work at El Dumpe involved collecting samples from this 1930s to 1940s dump. The University of Arizona Garbage Project coordinated data recovery and artifact analysis. The study focused on how the Depression and World War II affected Tucson residents. The findings suggest that some rationing took place during the war. Tucson residents also purchased more products bottled in glass during the war, a trend that continued afterward. An archival study provides a history of refuse disposal for the Tucson area. Excavations at the Embankment site uncovered a large stone foundation and associated features, including a large trash deposit. The building appears to have been torn down around 1944 or 1945. The artifacts recovered suggest the structure was a restaurant or tavern. Unfortunately, no surviving documents were found for the building.

description: An archaeological survey was conducted for Salt River Project (SRP) for a proposed extension of the Coronado Railroad right-of-way (ROW). The extended ROW occurs in two areas on private and State of Arizona lands in Apache County, Arizona. The survey was completed by SWCA, Inc. Environmental Consultants, under contract with SRP. The project was administered by Dr. Judy L. Brunson, SRP Archaeologist, and David H. Greenwald, SWCA Project Manager. The survey was completed by the author on January 18, 1991. The survey tracts, totaling approximately 13 acres, paralleled the existing Coronado Railroad line (c.f. Figures 1 and 2). The northern parcel parallels both sides of the existing railroad ROW on State of Arizona land and arcs with the curve of the railroad as it ascends out of the Puerco River Basin from the north and onto Puerco Ridge. The transects were 100 feet in width and approximately 1/4 mile in length. The parcel can be located on the 1972 Navajo South, Arizona, 7.5’ USGS topographic map in Township 19 North, Range 26 East, Section 24, NE 1/4 and is illustrated in figure 1 of this report. The southern parcel parallels the railroad ROW on its west side. This tract is 100 feet in width and 1/2 mile in length and can be located on the 1974 Ninemile Seep, Arizona, 7.5' USGS topographic map (photorevised 1984) in Township 18 North, Range 26 East extending from the NE 1/4 of the SE 1/4 of the SE 1/4 of Section 12 south to the SE 1/4 of the NE 1/4 of the NE 1/4 of Section 13. The survey parcel on Section 12 is on State of Arizona Land, while the survey parcel concerned with Section 13 is on private land. The parcel is illustrated in Figure 2 of this report.

description: It is expected that the Gross-Neveu-Yukawa (GNY) chiral Ising transition of $N$ Majorana (or $N_f=N/4$ four-component Dirac) fermions coupled with scalar field in (2+1)D will be the first fermionic quantum critical point that various methods such as conformal bootstrap [1], perturbative renormalization group [2] and quantum Monte Carlo (QMC) simulations [3], would yield the converged critical exponents -- serving the same textbook role as the Ising and $O(N)$ models in the statistical and quantum phase transition. However, such expectation has not been fully realized from the lattice QMC simulations due to the obstacles introduced by the UV finite size effect. In this work, by means of the elective-momentum ultra-size (EMUS) QMC method [4], we compute the critical exponents of the GNY $N=8$ chiral Ising transition on a 2D $π$-flux fermion lattice model between Dirac semimetal and quantum spin Hall insulator phases [3, 5]. With the matching of fermionic and bosonic momentum transfer and collective update in momentum space, our QMC results provide the fully consistent exponents with those obtained from the bootstrap and perturbative approaches. In this way, the Emus now live happily on the $N=8$ island and could explore the Gross-Neveu-Yukawa archipelago [1] with ease.

Development of a New Technique for Identifying Substrates of Protein Kinases
Creators: name: McCague, Karen Claire
Publisher: name: Imperial College London
Year: 2011

description: Protein phosphorylation, the most prevalent post-translational modification, is critical in the regulation of cellular events. Mapping the kinome is important in understanding how these processes occur and could provide a basis for new cancer therapies, but current methods are insufficient for this task. This research here was aimed at developing a new substrate identification strategy by combining two existing methods; steric complementation and cross-linking. Steric complementation was employed to generate a pyrazolo[3,4-d]pyrimidine ATP analogue that binds selectively to an analogue-sensitive (as-) kinase over the wild-type kinase and other intracellular kinases. The synthesis of C3-substituted pyrazolo[3,4-d]pyrimidines was extended to incorporate both alkyl and alkynyl substituents. A construct for the expression of PKCα (M417A) was generated and both PKCα and PKCα (M417A) expressed after lengthy optimisation. In vitro kinase radioassays were used to identify the most potent and selective inhibitor for PKCα (M417A). In order to allow late-stage introduction of photoactivatable groups into the pyrazolo[3,4-d]pyrimidine scaffold, various functionalised hydrazines were synthesised. The most potent C3-unsubstituted photoaffinity probes were selected for inhibition of PKCα and optimisation of both cross-linking and [3+2] Huisgen cyclisation to a fluorophore-containing azide allowed visualisation of the cross-linked products, although as yet, no substrate-selective labelling has been detected. The application of steric complementation to the photoaffinity probes was briefly investigated with a view to initially allowing improved detection of substrate-selective labelling, and ultimately achieving selective cross-linking to as-kinase substrates in intact cells.

description: Three-dimensional obstructed atomic insulators (OAIs) are characterized by the appearance of floating surface states (FSSs) at specific surfaces. Benefiting from this feature, our study here shows the presence of abundant surface-semimetal phases in 3D OAIs. The symmetries of obstructed Wannier charge centers ensure the degeneracy of such FSSs at high-symmetry points or invariant lines in the surface Brillouin zone. Utilizing topological quantum chemistry theory, we identify a carbon allotrope with a body-centered tetragonal structure, named bct-C20, as an ideal candidate for realizing different kinds of surface-semimetal phases. For the (001)surface of bct-C20, there are four in-gap FSSs, and these four FSSs form two kinds of surface Dirac cones, i.e., topological Dirac cones with linear dispersion and symmetry-enforced quadratic Dirac cones. The band topology of a surface Dirac cone is captured by the effective surface Hamiltonian and the emergence of hinge states. Moreover, the existence of the surface-nodal-line state is also discussed. This work reports an approach to obtain d-dimensional semimetal phases from the surface states of (d + 1)-dimensional systems, which is of great significance for the studies in revealing topological states and their practical applications in high-dimensional crystals.

description: We study U(1) and U(2) instanton solutions on noncommutative R^4 based on the noncommutative version of ADHM equation proposed by Nekrasov and Schwarz. It is shown that the anti-self-dual gauge fields on self-dual noncommutative R^4 correctly give integer instanton numbers for all cases we consider. We also show that the completeness relation in the ADHM construction is generally satisfied even for noncommutative spaces.
description: 15 pages, LaTex. v4: We now obtain the integer instanton number for our previous solutions after the correction of a numerical error, consistent with http://xxx.lanl.gov/abs/hep-th?0108007 by Chu, et al. It is also shown that the completeness relation is always satisfied, contrary to the claim by Chu, et al
Testing and Modeling Distributions of Returns and Volatility of Financial Assets
Creators: name: Zikes, Filip
Publisher: name: Imperial College London
Year: 2011

description: This thesis exploits the information contained in high-frequency data to test and model the distributions of returns of financial assets and their volatility. In Chapter 1 we study the asymptotics of some common tests for normality when applied to returns standardized by noise measures of volatility based on the use of high-frequency data. Chapter 2 proposes dynamic models for conditional quantiles of daily returns and realized volatility exploiting the information contained in various components of historical volatility as well as option-implied volatility. Chapter 3 provides a comprehensive simulation-based comparison of alternative tests for jumps in asset prices in order to get a better understanding of the performance of the tests under different, empirically relevant, scenarios. Chapter 4 extends the testing procedures studies in Chapter 1 to the multivariate context and provides new empirical evidence about the validity of the mixture of normals hypothesis in foreign exchange markets. Chapter 5 studies the dynamics of the tail risk in the hedge fund industry. Finally, Chapter 6 introduces a new method for estimating large covariance matrices.

description: New aspects of the complex sine-Gordon theory are addressed through the reformulation of the theory in terms of the gauged Wess-Zumino-Witten action. A dual transformation between the theory for the coupling constant $\b > 0$ and the theory for $\b < 0$ is given which agrees with the Krammers-Wannier duality in the context of perturbed conformal field theory. The Bäcklund transform and the nonlinear superposition rule for the complex sine-Gordon theory are presented and from which, exact solutions, solitons and breathers with U(1) charge, are derived. We clarify topological and nontopological nature of neutral and charged solitons respectively, and discuss about the duality between the vector and the axial U(1) charges.

description: In this paper, we study the hypercyclicity of forward and backward shifts on weighted $L^p$ spaces of a directed tree. In the forward case, only the trivial trees may support hypercyclic shifts, in which case the classical results of Salas apply. For the backward case, nontrivial trees may support hypercyclic shifts. We obtain necessary conditions and sufficient conditions for hypercyclicity of the backward shift and, in the case of a rooted tree on an unweighted space, we show that these conditions coincide.

description: The analysis of optical spectra - emission or absorption -- has been arguably the most powerful approach for discovering and understanding matters. The invention and development of many kinds of spectrometers have equipped us with versatile yet ultra-sensitive diagnostic tools for trace gas detection, isotope analysis, and resolving hyperfine structures of atoms and molecules. With proliferating data and information, urgent and demanding requirements have been placed today on spectrum analysis with ever-increasing spectral bandwidth and frequency resolution. These requirements are especially stringent for broadband laser sources that carry massive information, and for dispersive devices used in information processing systems. In addition, spectrum analyzers are expected to probe the device's phase response where extra information is encoded. Here we demonstrate a novel vector spectrum analyzer (VSA) that is capable of characterizing passive devices and active laser sources in one setup. Such a dual-mode VSA can measure loss, phase response and dispersion properties of passive devices. It also can coherently map a broadband laser spectrum into the RF domain. The VSA features a bandwidth of 55.1 THz (1260 to 1640 nm), frequency resolution of 471 kHz, and dynamic range of 56 dB. Meanwhile, our fiber-based VSA is compact and robust. It requires neither high-speed modulators and photodetectors, nor any active feedback control. Finally, we successfully employ our VSA for applications including characterization of integrated dispersive waveguides, mapping frequency comb spectra, and coherent light detection and ranging (LiDAR). Our VSA presents an innovative approach for device analysis and laser spectroscopy, and can play a critical role in future photonic systems and applications for sensing, communication, imaging, and quantum information processing.

description: The gauged sigma model with target $\mathbb{P}^1$, defined on a Riemann surface $Σ$, supports static solutions in which $k_+$ vortices coexist in stable equilibrium with $k_-$ antivortices. Their moduli space is a noncompact complex manifold $M_{(k_+,k_-)}(Σ)$ of dimension $k_++k_-$ which inherits a natural Kähler metric $g_{L^2}$ governing the model's low energy dynamics. This paper presents the first detailed study of $g_{L^2}$, focussing on the geometry close to the boundary divisor $D=\partial M_{(k_+,k_-)}(Σ)$. On $Σ=S^2$, rigorous estimates of $g_{L^2}$ close to $D$ are obtained which imply that $M_{(1,1)}(S^2)$ has finite volume and is geodesically incomplete. On $Σ=\mathbb{R}^2$, careful numerical analysis and a point-vortex formalism are used to conjecture asymptotic formulae for $g_{L^2}$ in the limits of small and large separation. All these results make use of a localization formula, expressing $g_{L^2}$ in terms of data at the (anti)vortex positions, which is established for general $M_{(k_+,k_-)}(Σ)$. For arbitrary compact $Σ$, a natural compactification of the space $M_{(k_+,k_-)}(Σ)$ is proposed in terms of a certain limit of gauged linear sigma models, leading to formulae for its volume and total scalar curvature. The volume formula agrees with the result established for $Vol(M_{(1,1)}(S^2))$, and allows for a detailed study of the thermodynamics of vortex-antivortex gas mixtures. It is found that the equation of state is independent of the genus of $Σ$, and that the entropy of mixing is always positive.

description: This novel excerpt from The Dagger was started as an attempt to understand the rise of alt-right extremist groups in the United States, as well as the conditions that made their rise possible. It aims to accomplish this through the perspective of a fictional young man from a middle-class background, Tom, who reaches adulthood near the apex of the movement’s overt social influence between 2014 and 2017. In the novel, Tom is drawn to a self-help and meditation retreat at a place called Sun Ranch, located in the Inland Empire of Southern California. The retreat, which targets disaffected young men of primarily white backgrounds, is led by a charismatic but reclusive yoga teacher named Curtis. In his lessons, he blends Californian interpretations of Hindu and Buddhist mysticism with fascist political precepts. As the retreat goes on, it becomes increasingly clear that Curtis has more than his students’ wellness in mind, and that he has a plan for the rights-based society he sees as his enemy.

Archaeological Overview
Site Evaluation / Testing

description: In the spring of 1984, Archaeological Research Services, Inc. was contracted by the Fort McDowell Mohave-Apache Indian Community to conduct data recovery at historic sites which would be impacted by Phase I of the Fort McDowell Irrigation Betterment Project. The sites are located on the Fort McDowell Indian Reservation, Maricopa County, Arizona. Nine sites were studied. Two of them were canals: the Government Ditch, dating from 1866 to ca 1940, and the Jones Ditch, dating from 1896 to present. Of the seven other sites, three were turn-of-the-century Anglo habitations later occupied by Yavapai, two were Yavapai sites, and two were historic features of mixed Yavapai and Anglo affiliation. Chapter 1 of this report reviews previous research on the reservation, states the research objectives of the present study, and describes the methods and sources of data used to accomplish these objectives. Chapter 2 provides an historical overview of the Fort McDowell Indian Reservation. Chapter 3 presents historical, ethnohistorical, and archaeological data from the nine sites in the project area. Chapter 4 integrates these data relative to project research objectives, and suggests directions for future research on the Fort McDowell Indian Reservation.
