3D gaze based semi-autonomous wheelchair
Creators: name: Subramanian, Mahendran
Publisher: name: Imperial College London
Year: 2022

description: A gaze-based semi-autonomous wheelchair was developed to control mobility platforms by decoding how the user looks at the environment to understand where they want to navigate their mobility device. However, many natural eye movements are not relevant for action intention decoding; only some are, which places a challenge on decoding, the so-called ‘Midas touch’ Problem. Herein, a new solution is presented, consisting of 1. deep computer vision to understand what object a user is looking at in their field of view, with 2. an analysis of where on the object’s bounding box the user is looking, to 3. use a simple machine learning classifier to determine whether the overt visual attention on the object is predictive of a navigation intention to that object. This decoding system ultimately determines whether the user wants to drive to, e.g., a TV or just looks at it. Crucially, we find that when users look at an object and imagine they were to interact with it, the resulting eye movements from this motor imagery (akin to neural interfaces) remain decodable. Once a driving intention and thus also the location is detected, our system instructs our autonomous wheelchair platform, the A.Eye-Drive, to navigate to the desired object while avoiding static and moving obstacles. Thus, we have realised a cognitive-level human interface for navigation purposes, as it requires the user only to cognitively interact with the desired goal, not to continuously steer their wheelchair to the target (low-level human interfacing).
Compliance and defiance in patron-client state relationships: a case study of Pakistan’s relationship with the united states, 1947-2013

description: By employing the theoretical construct of patron-client state relationships, this thesis conducts a historical analysis of the relationship between Pakistan and the United States from Pakistan’s independence in 1947 to its first successful transition from one elected government to another in 2013. Specifically, the thesis places particular emphasis on two conflicts with global implications in which the United States and Pakistan were closely aligned with each other: the covert war against the Soviet occupation of Afghanistan (1979-1989) and the ongoing war in Afghanistan since 2001 against the Taliban and al-Qaeda. Throughout these two periods, the US provided billions of dollars in military and economic assistance to Pakistan in exchange for services deemed essential for the attainment of America’s vital strategic and national security objectives. On both occasions, the client regime benefited from considerable latitude provided by the patron to pursue domestic and foreign policies aimed at consolidating its own hold on power and protecting what were regarded as fundamental national interests but not necessarily serving the avowed objectives of its patron. The US-Pakistan case study serves to highlight a fundamental contradiction that can characterise strategically driven patron-client state relationships. Instead of making the client more susceptible to the patron’s influence, increased assistance by the patron can actually make the client less likely to comply with the patron’s demands. This is especially true of relationships in which the patron regards the client’s cooperation as vitally important for the attainment of the patron’s core security interests. Paradoxically for the patron, the assistance that it provides to a strategically important client can end up undermining the very reasons that led to the provision of such assistance in the first place. Chief amongst those reasons are ensuring the client’s compliance and maintaining its internal stability. At the same time, as long as the patron’s own strategic interests necessitate a degree of client cooperation, it will find itself compelled to keep the relationship going, thereby giving the client continued room to deviate from the patron’s script to an extent where it can pursue its own national interests with relative impunity, confident in the knowledge that while its defiance might lead to occasional tensions with the patron, its continuing strategic importance will prevent a complete rupture and the consequent termination of material assistance.

description: Antiferromagnetic and charge ordered Hartree-Fock solutions of the one-band Hubbard model with on-site and nearest-neighbor Coulomb repulsions are exactly mapped onto an auxiliary local Kohn-Sham (KS) problem within a density-functional theory. The mapping provides a new insight into the interpretation of the KS equations. (i) With an appropriate choice of the basic variable, there is a universal form of the KS potential, which is applicable both for the antiferromagnetic and the charge ordered solutions. (ii) The Kohn-Sham and Hartree-Fock eigenvalues are interconnected by a scaling transformation. (iii) The band-gap problem is attributed to the derivative discontinuity of the basic variable as the function of the electron number, rather than a finite discontinuity of the KS potential. (iv) It is argued that the conductivity gap and the energies of spin-wave excitations can be entirely defined by the parameters of the ground state and the KS eigenvalues.

description: We investigate the parity ($\mathcal{P}$) and time-reversal ($\mathcal{T}$) symmetry violating effects in the CdH molecule and perform the relativistic coupled-cluster calculation of the molecular parameters- $E_\text{eff}$, $W_\text{s}$ and $W_\text{M}$ related to the electric dipole moment of electron (eEDM) interaction, the scalar-pseudoscalar (S-PS) nucleus-electron neutral current coupling and the nuclear magnetic quadrupole moment (MQM) interaction with electrons, respectively. We also compute the molecular dipole moment and the magnetic hyperfine structure coupling constant of CdH. The value of $E_\text{eff}$, $W_\text{s}$ and $W_\text{M}$ obtained by us in the said molecule are 12.2 GV/cm, 14.0 kHz and $0.82\times$10$^{33}$ Hz/e cm$^2$, respectively, within an uncertainty of 10\%. Furthermore, we study the trend of electron-correlation in the computed properties of CdH and that of the $\mathcal{P,T}$-odd parameters in the group-12 monohydrides (i.e., ZnH, CdH, and HgH).

description: Can vectors with low Schmidt rank form mutually unbiased bases? Can vectors with high Schmidt rank form positive under partial transpose states? In this work, we address these questions by presenting several new results related to Schmidt rank constraints and their compatibility with other properties. We provide an upper bound on the number of mutually unbiased bases of $\mathbb{C}^m\otimes\mathbb{C}^n$ $(m\leq n)$ formed by vectors with low Schmidt rank. In particular, the number of mutually unbiased product bases of $\mathbb{C}^m\otimes\mathbb{C}^n$ cannot exceed $m+1$, which solves a conjecture proposed by McNulty et al. Then we show how to create a positive under partial transpose entangled state from any state supported on the antisymmetric space and how their Schmidt numbers are exactly related. Finally, we show that the Schmidt number of operator Schmidt rank 3 states of $\mathcal{M}_m\otimes \mathcal{M}_n\ (m\leq n)$ that are invariant under left partial transpose cannot exceed $m-2$.

description: We consider a special type of interval catch digraph (ICD) for one-dimensional data in a randomized setting and propose its use for testing uniformity. These ICDs are defined with expansion and centrality parameters, hence are called parameterized ICDs (PICDs). We derive the exact (and asymptotic) distribution of the domination number of this PICD when its vertices are from a uniform (and non-uniform) distribution in one dimension for the entire parameter ranges; thereby determine the parameters for which the asymptotic distribution is non-degenerate. We use the domination number for testing uniformity of one-dimensional data, prove its consistency against certain alternatives, and compare it with commonly used and recently proposed tests in literature and also arc density of two ICD families in terms of size and power. Based on our Monte Carlo simulations, we demonstrate that PICD domination number has higher power for certain types of alternatives compared to other tests.

description: We analyse a simple example of a holographically dual pair in which we topologically twist both theories. The holography is based on the two-dimensional N=2 supersymmetric Liouville conformal field theory that defines a unitary bulk quantum supergravity theory in three-dimensional anti-de Sitter space. The supersymmetric version of three-dimensional Liouville quantum gravity allows for a topological twist on the boundary and in the bulk. We define the topological bulk supergravity theory in terms of twisted boundary conditions. We corroborate the duality by calculating the chiral configurations in the bulk supergravity theory and by quantising the solution space. Moreover, we note that the boundary calculation of the structure constants of the chiral ring carries over to the bulk theory as well. We thus construct a topological AdS/CFT duality in which the bulk theory is independent of the boundary metric.

description: Obesity, known to cause a systemic elevation in monocyte chemotactic protein-1 (MCP-1), adversely affects normal ovarian function. The aim of this study was to determine whether MCP-1 plays a role in ovarian dysfunction that is related to obesity induced by high-fat (HF) diet intake. Wild type (WT) C57BL/6J mice were fed either normal chow (NC) (Group 1, control group) or HF diet (Group 2). To assess whether MCP-1 is involved in HF-diet-induced ovarian dysfunction, MCP-1 knock-out mice were fed HF diet (Group 3). Body weight, body fat composition, number of oocytes collected following ovarian superovulation with gonadotropins, ovarian macrophage markers and expression of genes important in folliculogenesis and steroidogenesis were quantified in the 3 groups of animals. Animals in Group 2 gained significant body weight and body mass, produced the fewest number of oocytes following superovulation, and had significant alterations in ovarian genes involved in folliculogenesis and steroidogenesis as well as genes involved in inflammation. Although animals in Group 3 had the highest body weight and body fat composition, they produced similar number of oocytes compared to animals in Group 1 but had different ovarian gene expression compared to Group 2. These findings suggest that MCP-1 gene knockout could reverse some of the adverse effects of obesity induced by HF diet intake. Future studies assessing ovarian histology in MCP-1 knock out mouse model will confirm our findings. MCP-1 inhibition could represent a future therapeutic target to protect ovarian health from the adverse effects of HF diet ingestion.

description: We experimentally realize a Peierls phase in the hopping amplitude of excitations carried by Rydberg atoms, and observe the resulting characteristic chiral motion in a minimal setup of three sites. Our demonstration relies on the intrinsic spin-orbit coupling of the dipolar exchange interaction combined with time-reversal symmetry breaking by a homogeneous external magnetic field. Remarkably, the phase of the hopping amplitude between two sites strongly depends on the occupancy of the third site, thus leading to a correlated hopping associated to a density-dependent Peierls phase. We experimentally observe this density-dependent hopping and show that the excitations behave as anyonic particles with a non-trivial phase under exchange. Finally, we confirm the dependence of the Peierls phase on the geometrical arrangement of the Rydberg atoms.

description: A many-body wavefuction is postulated, which is sufficiently general to describe superconducting pair-correlations, and/or spin-correlations, which can occur either as long-range order or as finite-range correlations. The proposed wave-function appears to summarize some of the more relevant aspects of the rich phase-diagram of the high-Tc cuprates. Some of the states represented by this wavefunction are reviewed: For superconductivity in the background of robust anti-ferromagnetism, the Cooper-pairs are shown to be a superposition of spinquantum numbers S=0 and S=1. If the anti-ferromagnetism is weak, a continuous super-symmetric rotation is identified connecting s-wave superconductivity to anti-ferromagnetism.

Flaming and smouldering hazards in large timber compartments
Creators: name: Mitchell, Harry
Publisher: name: Imperial College London
Year: 2024

description: The use of large timber elements (mass timber) in buildings instead of concrete and steel can improve sustainability, aesthetics, construction times, and costs. However, the adoption of mass timber in high-rise buildings is currently hindered by concerns regarding safety and structural performance in fire. This thesis finds a lack of experimental data for large compartment fire experiments (floor area > 100 m2). Therefore, this thesis introduces CodeRed, the largest mass timber compartment fire experiments to date, with a floor area of 352 m2, and a mass timber ceiling and columns. A fire-resistant camera array was iteratively designed to improve data retrieval and positioned around the compartments to study fire behaviour via visual diagnostics. Three hazards that have not been studied significantly in the literature were studied in-depth, including flame spread, smouldering of timber elements, and firebrands, which are burning pieces of timber ejected from compartment openings. Compared to previous large concrete experiments, inclusion of a timber ceiling increased flame spread rates, reduction of the density of the fuel load inside the compartment reduced the rate of spread, and the addition of ceiling encapsulation delayed ceiling ignition. During the experiments, approximately 4500 firebrands were ejected from a single opening, posing a potential ignition hazard. Increased firebrand quantities and velocities were observed where external flaming occurs. Over the 48 h after the end of flames, nineteen smouldering hotspots were studied over three experiments. Hotspots developed along the edges of timber elements where heat losses are minimised at a density of 0.012-0.58 hotspots per meter of timber edge. Hotspot phenomena including spread, self-extinguishment, and transition to flaming. Glulam column collapse and formation of nine holes in the timber ceiling were studied. Overall, this thesis introduces valuable findings on understudied hazards in timber buildings that can be mitigated to improve fire-safe modern timber construction.

description: IFNL2 is a potent antiviral interferon, but the regulation of its gene expression is not fully clear. Here, we report the regulation of ATG10S for IFNL2 transcription. Through sequential deletion of the IFNL2 promoter sequence, we found LP1-1, a fragment of the promoter responding to ATG10S activity. Subcellular localization and DNA immunoprecipitation assays showed ATG10S translocating into the nucleus and binding to LP1-1. Online prediction for transcription factor binding sites showed an IRF1 targeting locus in LP1-1. Luciferase assays, RT-PCR, and western blot analysis revealed a core motif (CAAGAC) existing in LP1-1, which determined ATG10S and IRF1 activity; individual nucleotide substitution showed that the functional nucleotides of ATG10S targeting were C1, A3, and C6, and the ones associated with IRF1 were A3 and G4 within the core motif. Co-immunoprecipitation assays revealed ATG10S combination with KPNA1/importin α, KPNB1/importin β, and IRF1. The knockdown of endogenous IRF1 increased ATG10S activity on IFNL2 transcription. These results indicate that ATG10S as a transcription factor competes with IRF1 for the same binding site to promote IFNL2 gene transcription.

description: In this paper, we examine the performance of four fuzzy rule generation methods on Wisconsin breast cancer data. The first method generates fuzzy if then rules using the mean and the standard deviation of attribute values. The second approach generates fuzzy if then rules using the histogram of attributes values. The third procedure generates fuzzy if then rules with certainty of each attribute into homogeneous fuzzy sets. In the fourth approach, only overlapping areas are partitioned. The first two approaches generate a single fuzzy if then rule for each class by specifying the membership function of each antecedent fuzzy set using the information about attribute values of training patterns. The other two approaches are based on fuzzy grids with homogeneous fuzzy partitions of each attribute. The performance of each approach is evaluated on breast cancer data sets. Simulation results show that the Modified grid approach has a high classification rate of 99.73 %.

description: In the paper we study propagation of light in general relativity through a spacetime filled with cold plasma with infinite conductivity. We use the geometric optics based on Synge's approach. As the main result we provide a formula for calculation of spectral flux of radiation emitted from a pointlike source. The formula employs connecting vectors that are obtained by integrating the ray deviation equation along the reference ray connecting the source and observation event. As a byproduct we formulate Etherington's reciprocity theorem with the inclusion of plasma, interrelating angular size distance and luminosity distance. We also discuss the Liouville theorem and its formulation in terms of connecting vectors.

Mechanical tension in pancreatic ductal adenocarcinoma progression
Creators: name: Vella, Alain
Publisher: name: Imperial College London
Year: 2023

description: Healthy biological tissues are constantly acted upon by physiological mechanical stimuli. Perturbations of these mechanical stimuli are however implicated in diseases such as cancer. Amongst these stimuli, accumulated solid stresses are a hallmark of pancreatic ductal adenocarcinoma (PDAC) and are increasingly being recognised as a novel and distinct promoter of tumour growth and spread. It is hypothesised that tensile stresses which accumulate at the periphery of PDAC tumours promote activation of the stroma in adjacent healthy tissues, laying the groundworks for PDAC progression. This project modelled the growth of PDAC tumours computationally and found that tissues in the peritumoural stroma are subjected to high in-plane tensile stresses. Uniaxial stretching was applied to cell cultures in vitro to analyse the effect of these stresses. Stretching downregulated E-cadherin expression in epithelial cells, suggesting that mechanical tension may contribute to epithelial to mesenchymal transition. Subsequent stretching of pancreatic stellate cells (PSCs), key regulators of the PDAC physical microenvironment, on an equibiaxial cell stretching device evidenced increases in collagen I protein synthesis as well as an NF-κB mediated upregulation of vascular growth factor A (VEGF-A) expression. By establishing that stretching of PSCs induces pro-fibrotic and pro-angiogenic behaviours, these novel findings within the context of PDAC support the hypothesis that mechanical tension contributes to stromal activation in PDAC. The findings from this research are intended to support studies which seek to clarify the prognostic role of activated PDAC stroma and the merits of stromal modification.

description: Spin-momentum locking, a key property of the surface states of three-dimensional topological insulators (3DTIs), provides a new avenue for spintronics applications. One consequence of spin-momentum locking is the induction of surface spin accumulations due to applied electric fields. In this work, we investigate the extraction of such electrically-induced spins from their host TI material into adjoining conventional, hence topologically trivial, materials that are commonly used in electronics devices. We focus on effective Hamiltonians for bismuth-based 3DTI materials in the ${\rm Bi}_2{\rm Se}_3$ family, and numerically explore the geometries for extracting current-induced spins from a TI surface. In particular, we consider a device geometry in which a side pocket is attached to various faces of a 3DTI quantum wire and show that it is possible to create current-induced spin accumulations in these topologically trivial side pockets. We further study how such spin extraction depends on geometry and material parameters, and find that electron-hole degrees of freedom can be utilized to control the polarization of the extracted spins by an applied gate voltage.

description: A graph polynomial $P$ is weakly distinguishing if for almost all finite graphs $G$ there is a finite graph $H$ that is not isomorphic to $G$ with $P(G)=P(H)$. It is weakly distinguishing on a graph property $\mathcal{C}$ if for almost all finite graphs $G\in\mathcal{C}$ there is $H \in \mathcal{C}$ that is not isomorphic to $G$ with $P(G)=P(H)$. We give sufficient conditions on a graph property $\mathcal{C}$ for the characteristic, clique, independence, matching, and domination and $ξ$ polynomials, as well as the Tutte polynomial and its specialisations, to be weakly distinguishing on $\mathcal{C}$. One such condition is to be addable and small in the sense of C. McDiarmid, A. Steger and D. Welsh (2005). Another one is to be of genus at most $k$.

Designing for human connectivity in fourth places
Creators: name: Mahdy, Islam
Publisher: name: Imperial College London
Year: 2024

description: In an era of increasing remote work, a duality of enhanced connectivity and isolation emerges, emphasizing the need for human-centric design in Fourth Places — where life, work, and leisure intersect. This research traverses behavioural and experiential design, aiming to unlock pathways for enriched human connectivity in these multidimensional spaces. Taking an interdisciplinary approach, the study delves into design, social psychology, and behavioural science, unravelling users' experiences within Fourth Places. It aims to bridge the gap between a growing psychological need for connectivity and the dynamic nature of these environments. The first two chapters lay the groundwork, shedding light on the motivations behind the research and the existing knowledge void. They pave the way for an exploration of the complexities of Fourth Places and their role in societal disconnection. Chapter three employs surveys and epistolary interviews to gain user insights, unearthing their expectations and experiences. Chapter four lean on expert perspectives, revealing industry and design challenges and prospects. Each segment of the study builds upon the previous, culminating in participatory observations and behavioural analyses that identify disparities between user desires and industry deliverables. This exhaustive exploration births adaptable Design Principles, offering a blueprint for crafting environments in Fourth Places that cater to the nuanced needs of the remote workforce. The insights presented herein introduce transformative solutions, emphasizing adaptive environments that promote community and human connectivity. The research, hence, not only bridges the chasm between user needs and industry solutions but also redefines paradigms of connectivity in our present-day fragmented world. This thesis stands as a potent testament to the future of living, working, and socializing in an ever-evolving global landscape.

description: This is a supplement of A Systematic Review and Meta-analysis.
The incidence of thyroid cancer has increased worldwide. In the United States, for instance, the incidence of thyroid cancer increased from a 4.9 to 14.2 per 100,000 person-years over the last two decades, while in South Korea, on the other hand, thyroid cancer increased by more than seven fold, from 6.3 per 100,000 person year in 1999 to 47.5 per 100,000 population in 2009.
 Understanding the method of thyroid cancer detection has potential implications on interpreting incidence rates, the diagnosis and management of thyroid cancer. The aim of this study is to summarize the available evidence to assess the frequency of incidental (asymptomatic) and non-incidental TC and examine the triggers that lead to diagnosis with comparison across multiple cohorts.
Phase Space Cell in Nonextensive Classical Systems

description: We calculate the phase space volume $Ω$ occupied by a nonextensive system of $N$ classical particles described by an equilibrium (or steady-state, or long-term stationary state of a nonequilibrium system) distribution function, which slightly deviates from Maxwell-Boltzmann (MB) distribution in the high energy tail. We explicitly require that the number of accessible microstates does not change respect to the extensive MB case. We also derive, within a classical scheme, an analytical expression of the elementary cell that can be seen as a macrocell, different from the third power of Planck constant. Thermodynamic quantities like entropy, chemical potential and free energy of a classical ideal gas, depending on elementary cell, are evaluated. Considering the fractional deviation from MB distribution we can deduce a physical meaning of the nonextensive parameter $q$ of the Tsallis nonextensive thermostatistics in terms of particle correlation functions (valid at least in the case, discussed in this work, of small deviations from MB standard case). pacs: 05.20.-y, 05.70.-a keywords: Classical Statistical Mechanics, Thermodynamics

Thermal denaturation of an helicoidal DNA model

description: We study the static and dynamical properties of DNA in the vicinity of its melting transition, i.e. the separation of the two strands upon heating. The investigation is based on a simple mechanical model which includes the helicoidal geometry of the molecule and allows an exact numerical evaluation of its thermodynamical properties. Dynamical simulations of long-enough molecular segments allow the study of the structure factors and of the properties of the denaturated regions. Simulations of finite chains display the hallmarks of a first order transition for sufficiently long-ranged stacking forces although a study of the model's ``universality class'' strongly suggests the presence of an ``underlying'' continuous transition.

description: Poincaré-Sobolev-type inequalities involving rearrangement-invariant norms on the entire $\mathbb{R}^n$ are provided. Namely, inequalities of the type $\|u-P\|_{Y(\mathbb{R}^n)}\leq C\|\nabla^m u\|_{X(\mathbb{R}^n)}$, where $X$ and $Y$ are either rearrangement-invariant spaces over $\mathbb{R}^n$ or Orlicz spaces over $\mathbb{R}^n$, $u$ is a $m-$times weakly differentiable function whose gradient is in $X$, $P$ is a polynomial of order at most $m-1$, depending on $u$, and $C$ is a constant independent of $u$, are studied. In a sense optimal rearrangement-invariant spaces or Orlicz spaces $Y$ in these inequalities when the space $X$ is fixed are found. A variety of particular examples for customary function spaces are also provided.

description: Within the framework of on-line learning, we study the generalization error of an ensemble learning machine learning from a linear teacher perceptron. The generalization error achieved by an ensemble of linear perceptrons having homogeneous or inhomogeneous initial weight vectors is precisely calculated at the thermodynamic limit of a large number of input elements and shows rich behavior. Our main findings are as follows. For learning with homogeneous initial weight vectors, the generalization error using an infinite number of linear student perceptrons is equal to only half that of a single linear perceptron, and converges with that of the infinite case with O(1/K) for a finite number of K linear perceptrons. For learning with inhomogeneous initial weight vectors, it is advantageous to use an approach of weighted averaging over the output of the linear perceptrons, and we show the conditions under which the optimal weights are constant during the learning process. The optimal weights depend on only correlation of the initial weight vectors.

description: We give a review of the tomographic probability representation of quantum mechanics. We present the formalism of quantum states and quantum observables using the formalism of standard probability distributions and classical-like random variables. We study the coherent and number states of photons in the probability representation and obtain the evolution equation and energy spectra in the form of equations for probability distributions.

description: In this paper we have proposed a semi-heuristic optimization algorithm for designing optimal plant layouts in process-focused manufacturing/service facilities. Being a semi-heuristic search, our algorithm is likely to be more efficient in terms of computer CPU engagement time as it tends to converge on the global optimum faster than the traditional CRAFT algorithm - a pure heuristic.
