description: Dry matter accumulation and nutrient uptake patterns of crops must be determined to optimize fertilizer scheduling. This study assesses the dry matter accumulation and nutrient uptake patterns of onion seed crop. Plant samples were collected between 0 and 120 days after planting, and their nutrient content was analyzed to determine the dry matter accumulation and nutrient uptake patterns. The quantity and period of nutrient uptake and the mobility of nutrients within the plant parts varied for different nutrients. The absorption of nitrogen (N) and potassium (K) was the highest during vegetative stage, whereas phosphorus (P) and sulfur (S) uptake was the highest during flower initiation stage. N, P, K, and S, which had accumulated in the vegetative parts, moved from the senesced vegetative parts to the inflorescence during the reproductive stages owing to their high mobility in the phloem. The onion plants continued to absorb zinc, copper, manganese, and iron throughout their growth owing to the immobility of these elements in plant system. The result of this study may facilitate efficient scheduling of fertilizer application to increase nutrient uptake and yield.

description: We propose a framework to solve non-linear and history-dependent mechanical problems based on a hybrid classical computer -- quantum annealer approach. Quantum Computers are anticipated to solve particular operations exponentially faster. The available possible operations are however not as versatile as with a classical computer. However, quantum annealers (QAs) are well suited to evaluate the minimum state of a Hamiltonian quadratic potential. Therefore, we reformulate the elasto-plastic finite element problem as a double-minimisation process framed at the structural scale using the variational updates formulation. In order to comply with the expected quadratic nature of the Hamiltonian, the resulting non-linear minimisation problems are iteratively solved with the suggested Quantum Annealing-assisted Sequential Quadratic Programming (QA-SQP): a sequence of minimising quadratic problems is performed by approximating the objective function by a quadratic Taylor's series. Each quadratic minimisation problem of continuous variables is then transformed into a binary quadratic problem. This binary quadratic minimisation problem can be solved on quantum annealing hardware such as the D-Wave system. The applicability of the proposed framework is demonstrated with one- and two-dimensional elasto-plastic numerical benchmarks. The current work provides a pathway of performing general non-linear finite element simulations assisted by quantum computing.

description: This paper shows how Graph Neural Networks can be used for learning distributed coordination mechanisms in connected teams of robots. We capture the relational aspect of robot coordination by modeling the robot team as a graph, where each robot is a node, and edges represent communication links. During training, robots learn how to pass messages and update internal states, so that a target behavior is reached. As a proxy for more complex problems, this short paper considers the problem where each robot must locally estimate the algebraic connectivity of the team's network topology.

description: We use junctions of critical spin-1 chains as the basic elements to construct a honeycomb network that harbors a gapless chiral spin liquid phase. The low-energy modes are described by spin-1 Majorana fermions that form a two-dimensional Fermi surface when the interactions at the junctions are tuned to the vicinity of chiral fixed points with staggered chirality. We discuss the physical properties and the stability of this chiral spin liquid phase against perturbations from the point of view of the effective field theory for the network. We find clear connections with the excitation spectrum obtained in parton constructions on the kagome lattice.

Mechanistic insights in to pore formation by the MACPF superfamily
Creators: name: Boyd, Courtney Margaret
Publisher: name: Imperial College London
Year: 2018

description: Pore-forming proteins are a ubiquitous class of molecule that function in a variety of roles ranging from cellular attack to cellular defence. Despite a range of sizes and architectures, the majority of pore-forming proteins follow the same general mechanism of action, whereby soluble monomers, secreted by the host cell, bind target membranes and oligomerise to form transmembrane pores. One class of pore-forming proteins is the membrane attack complex/perforin-like (MACPF) superfamily, which has members that function in both immune and pathological roles. Two members of this family are the bacterial toxin intermedilysin (ILY) and the human immune pore the membrane attack complex (MAC). With roles in highly diverse processes, these two MACPF proteins are related through their regulation by the human immune receptor CD59. This small surface receptor, found on a wide range of human tissues, contributes to a variety of human diseases on dysregulation. Using a range of biophysical and structural techniques, the work presented in this thesis is focused on increasing our understanding of how these two disparate yet related pore-forming proteins function. For ILY, investigation into the structural transitions associated with cholesterol and CD59 indicated that CD59 is the main driver behind the key conformation changes required for pore formation and was hypothesised to set the specific curvature of the ILY pore. Additionally, a novel disulphide-locked mutant which was unable to form membrane inserted pores was shown to form a homogeneous 35-mer, highlighting it as a promising candidate for future structural studies. In conjunction to work on ILY, analysis of the mechanism of pore formation by the MAC via cryo-electron microscopy exhibited its unique process of pore closure, a result of the heterogeneous nature of this complex. Building on a previously published structure, the resolution of both the complete MAC structure and 2 conformational intermediates was achieved, as well as the first high-resolution map of the membrane-inserted form of the major MAC constituent C9. These maps formed the basis for both flexible fitting and atomic modelling of all 5 MAC components, providing new insights into how the MAC is formed. Understanding how these pore-forming proteins are assembled will be key in aiding design of new and exciting therapeutics aimed at regulating these important transmembrane complexes.

description: Bound orbits of black holes are very well understood. Given a Kerr black hole of mass $M$ and spin $S = aM^2$, it is simple to characterize its orbits as functions of the orbit's geometry. How do the orbits change if the black hole is itself evolving? How do the orbits change if the orbiting body evolves? In this paper, we consider a process that changes a black hole's mass and spin, acting such that the spacetime is described by the Kerr solution at any moment, or that changes the orbiting body's mass. Provided this change happens slowly, the orbit's actions ($J_r, J_θ, J_ϕ$) are {\it adiabatic invariants}, and thus are constant during this process. By enforcing adiabatic invariance of the actions, we deduce how an orbit evolves due to changes in the black hole's mass and spin and in the orbiting body's mass. We demonstrate the impact of these results with several examples: how an orbit responds if accretion changes a black hole's mass and spin; how it responds if the orbiting body's mass changes due to accretion; and how the inspiral of a small body into a black hole is affected by change to the hole's mass and spin due to the gravitational radiation absorbed by the event horizon. In all cases, the effect is very small, but can be an order of magnitude or more larger than what was found in previous work which did not take into account how the orbit responds due to these effects.

description: We investigate the problem of corruption robustness in offline reinforcement learning (RL) with general function approximation, where an adversary can corrupt each sample in the offline dataset, and the corruption level $ζ\geq0$ quantifies the cumulative corruption amount over $n$ episodes and $H$ steps. Our goal is to find a policy that is robust to such corruption and minimizes the suboptimality gap with respect to the optimal policy for the uncorrupted Markov decision processes (MDPs). Drawing inspiration from the uncertainty-weighting technique from the robust online RL setting \citep{he2022nearly,ye2022corruptionrobust}, we design a new uncertainty weight iteration procedure to efficiently compute on batched samples and propose a corruption-robust algorithm for offline RL. Notably, under the assumption of single policy coverage and the knowledge of $ζ$, our proposed algorithm achieves a suboptimality bound that is worsened by an additive factor of $\mathcal{O}(ζ(C(\widehat{\mathcal{F}},μ)n)^{-1})$ due to the corruption. Here $\widehat{\mathcal{F}}$ is the confidence set, and the dataset $\mathcal{Z}_n^H$, and $C(\widehat{\mathcal{F}},μ)$ is a coefficient that depends on $\widehat{\mathcal{F}}$ and the underlying data distribution $μ$. When specialized to linear MDPs, the corruption-dependent error term reduces to $\mathcal{O}(ζd n^{-1})$ with $d$ being the dimension of the feature map, which matches the existing lower bound for corrupted linear MDPs. This suggests that our analysis is tight in terms of the corruption-dependent term.

description: Objective: To better understand how meteorological variables, air quality variables, and pollen counts collectively contribute to asthma-related emergency department visits (AREDV) and asthma-related hospitalizations (ARH) among pediatric and adult patients in the New York City borough of the Bronx. Methods: The numbers of daily adult and pediatric AREDV and ARH from 2001 to 2008 were obtained from three Bronx hospitals. After removing outliers, interpolating missing data, and standardizing variable values by scaling the data using z-scores, data were analyzed using Spearman rank tests and linear regression models for the full year and each season. Results: There were a total of 42,065 AREDV and 1,664 ARH at both Bronx hospitals. With the exception of a spring peak in AREDVs, AREDVs and ARHs follow a cyclical pattern, climbing in the fall, plateauing in the winter, dropping in the spring, and reaching a low in the summer. Among the 11 air quality, meteorological, and pollen count variables, temperature and tree pollen made the greatest contribution to AREDV with scaled coefficients of –0.337 and 0.311 respectively; equating to an additional AREDV for every 5.0-unit decrease in temperature and an additional AREDV for every 186.0-unit increase in tree pollen. These two variables were confirmed to have independent associations with AREDV prior to the data interpolation. Grass pollen was also found to have a relatively large contribution to AREDV during the summer with a scaled coefficient of 0.314, equating to an additional AREDV for every 2.3-unit increase in grass pollen. Conclusion: There are distinct peaks of increased AREDVs that are closely associated with increased tree pollen counts in the spring and decreasing temperatures in the fall. Early anticipation of these air quality, meteorological, and pollen factor changes based on ongoing surveillance could potentially guide clinical practice and minimize AREDVs in the Bronx.

Adjoint based analysis for swirling and reacting flows
Creators: name: Skene, Calum Scott
Publisher: name: Imperial College London
Year: 2019

description: Adjoint techniques are a useful tool in applied mathematics, enabling the efficient evaluation of gradient information. This thesis showcases the use of adjoints in a reacting and swirling flow setting. Additionally, algorithmic techniques are developed to facilitate the use of adjoints for the complicated governing equations that arise from reacting flow. A resolvent study of an M-flame is conducted to determine the optimal forcing that provides the greatest amplification in flow dynamics. This study extends the concept of a flame transfer function to provide structural mechanisms through which amplification is obtained. Adjoint information is used to efficiently conduct the study, and to extend its validity to different parameter values. A blend of the Orr mechanism and other mechanisms that make use of the azimuthal shear is found to provide the optimal gain, which is achieved for the $m=2$ azimuthal mode in the non-swirling case, with a change to the $m=0$ mode when swirl is introduced. A weakly non-linear analysis of an incompressible swirling jet is also performed to determine how harmonic forcing modifies the precessing instability caused by high swirl. This study reveals that forcing against the mean-flow swirl causes stabilisation of the instability, with axisymmetric and co-rotating forcing leading to destabilisation. In both cases the base-flow modification induced by the driven response provides the key mechanism through which the unstable mode is modified. A generalised, alternative formulation to this problem is also developed in which the weakly non-linear equations are found directly from the numerical code via finite differences, allowing for future analyses to be carried out for complex governing equations. Lastly, an algorithmic study is conducted, showing how direct-adjoint looping can be accelerated using a parallel-in-time approach. This technique is found to be beneficial for both linear and non-linear governing equations, leading to more efficient optimisation studies.
An assessment of the applicability of data based mechanistic modelling to flood forecasting in the UK
Creators: name: Vaughan, Michael David
Publisher: name: Imperial College London
Year: 2018

description: The data-based mechanistic (DBM) modelling methodology has previously been proposed for developing real-time flood forecasting models. However, only limited research has been published comparing the performance of DBM models with commonly used conceptual rainfall runoff (CRR) models and investigating the predictive performance of DBM models when transferred in time to conditions outside the range of their calibration data. This thesis reports a case study performance comparison of DBM and CRR rainfall runoff models, including temporal transfer, across a range of forecasting performance measures. The DBM models were based upon the range of model structures and parameter estimation approaches used in other published studies, and did not attempt to exhaustively explore the potential of the DBM methodology. The principal findings are that the employed DBM models could not improve upon the CRR models and that neither model type performed well when transferred in time to conditions outside the range of their calibration data. The performance comparison was followed-up with a synthetic catchment study to investigate the role of model (as opposed to data) errors on the predictive performance of DBM models when transferred in time to conditions outside the range of their calibration data. This work found that the DBM modelling approach as applied here cannot be relied upon to estimate models that will transfer satisfactorily in time, even with error-free data, indicating that shortcomings in temporal transferability are intrinsic to the modelling process. The work further found that calibration performance was not a reliable predictor of temporal transferability amongst a set of identified candidate models. The flexibility of DBM methodology does, however, make it suitable for incorporating future developments, aimed at mitigating the identified shortcomings. Potential areas of investigation include the use of alternative model structures and optimisation schemes, as well as the use of hybrid DBM-CRR models.

description: Star formation in galaxies appears to be self-regulated by energetic feedback processes. Among the most promising agents of feedback are cosmic rays (CRs), the relativistic ion population of interstellar and intergalactic plasmas. In these environments, energetic CRs are virtually collisionless and interact via collective phenomena mediated by kinetic-scale plasma waves and large-scale magnetic fields. The enormous separation of kinetic and global astrophysical scales requires a hydrodynamic description. Here, we develop a new macroscopic theory for CR transport in the self-confinement picture, which includes CR diffusion and streaming. The interaction between CRs and electromagnetic fields of Alfvénic turbulence provides the main source of CR scattering, and causes CRs to stream along the magnetic field with the Alfvén velocity if resonant waves are sufficiently energetic. However, numerical simulations struggle to capture this effect with current transport formalisms and adopt regularization schemes to ensure numerical stability. We extent the theory by deriving an equation for the CR momentum density along the mean magnetic field and include a transport equation for the Alfvén-wave energy. We account for energy exchange of CRs and Alfvén waves via the gyroresonant instability and include other wave damping mechanisms. Using numerical simulations we demonstrate that our new theory enables stable, self-regulated CR transport. The theory is coupled to magneto-hydrodynamics, conserves the total energy and momentum, and correctly recovers previous macroscopic CR transport formalisms in the steady-state flux limit. Because it is free of tunable parameters, it holds the promise to provide predictable simulations of CR feedback in galaxy formation.

description: We compute the pseudo entropy in two-dimensional holographic and free Dirac fermion CFTs for excited states under joining local quenches. Our analysis reveals two of its characteristic properties that are missing in the conventional entanglement entropy. One is that, under time evolution, the pseudo entropy exhibits a dip behavior as the excitations propagate from the joined point to the boundaries of the subsystem. The other is that the excess of pseudo entropy over entanglement entropy can be positive in holographic CFTs, whereas it is always non-positive in free Dirac fermion CFTs. We argue that the entropy excess can serve as a measure of multi-partite entanglement. Its positivity implies that the vacuum state in holographic CFTs possesses multi-partite entanglement, in contrast to free Dirac fermion CFTs.

description: Gravitational lensing has emerged as a powerful probe of the matter distribution on subgalactic scales, which itself may contain important clues about the fundamental origins and properties of dark matter. Broadly speaking, two different approaches have been taken in the literature to map the small-scale structure of the Universe using strong lensing, with one focused on measuring the position and mass of a small number of discrete massive subhalos appearing close in projection to lensed images, and the other focused on detecting the collective effect of all the small-scale structure between the lensed source and the observer. In this paper, we follow the latter approach and perform a detailed study of the sensitivity of galaxy-scale gravitational lenses to the ensemble properties of small-scale structure. As in some previous studies, we adopt the language of the substructure power spectrum to characterize the statistical properties of the small-scale density field. We present a comprehensive theory that treats lenses with extended sources as well as those with time-dependent compact sources (such as quasars) in a unified framework for the first time. Our approach uses mode functions to provide both computational advantages and insights about couplings between the lens and source. The goal of this paper is to develop the theory and gain the intuition necessary to understand how the sensitivity to the substructure power spectrum depends on the source and lens properties, with the eventual aim of identifying the most promising targets for such studies.

description: We present a first complete implementation of an effective-one-body (EOB) model for extreme-mass-ratio inspirals (EMRIs) that incorporates aligned spins (on both the primary and the secondary) as well as orbital eccentricity. The model extends TEOBResumS-Dalí for these binaries by (i) recasting conservative first-order gravitational self-force (1GSF) information in the resummed EOB potentials; (ii) employing a post-Newtonian (PN) $3^{+19}$PN-accurate (3PN comparable-mass terms hybridized with test-particle terms up to 22PN relative order) expression for the gravitational-wave flux at infinity; (iii) using an improved implementation of the horizon flux that better approximates its test-mass representation. With respect to our previous work [Phys. Rev. D 106 (2022) 8, 084062], we demonstrate that the inclusion of the $3^{+19}$PN-accurate $\ell=9$ and $\ell=10$ modes in the flux at infinity significantly improves the model's agreement with second-order accurate GSF (2GSF) circular waveforms. For a standard EMRI with mass ratio $q \equiv m_1/m_2 = 5 \times 10^4$ and $m_2 = 10 M_\odot$, the accumulated EOB/2GSF dephasing is $\lesssim $ rad for $\sim 1$ yr of evolution, which is consistent with the standard accuracy requirements for EMRIs. We also showcase the generation of eccentric and spinning waveforms and discuss future extensions of our EOB towards a physically complete model for EMRIs.

The relationship between pro-inflammatory cytokines and prostaglandin production in the human amnion
Creators: name: Das, Ananya
Publisher: name: Imperial College London

description: Preterm labour (PTL) management may be improved through better understanding of term labour. Existing research suggests that myometrial inflammation stimulates the initiation of labour at term. However, this theory has recently been challenged by group data, derived from a collection of gestational tissues. In this thesis, amnion samples were selected and prolabour gene expression, inflammation and the steroid receptor pathways for the glucocorticoid and progesterone receptors (PRs) studied. It was hypothesised that (i) amnion inflammation occurs in early labour (TEaL) and, consequently, may have a role in the onset of human parturition; (ii) prolabour gene expression is increased in amnion samples in TEaL and that (iii) both are related to a decline in progesterone (P4) signalling. It was also speculated whether (iv) P4 acts via PRs and not glucocorticoid receptors (GRs) and whether (v) P4 function in the amnion can be enhanced by the addition of cyclic AMP were investigated. Analysis suggested that amnion inflammation occurs predominantly in TEsL but also in TEaL leaving it unclear whether amnion inflammation has a role in human labour onset. Increased prolabour gene expression was observed more significantly in TEsL and in PTL, was dependent on the underlying aetiology. Human amnion epithelial cells were acquired from women undergoing term elective caesarean section. Cells were treated with P4 and a cAMP agonist, forskolin, independently and in combination, to investigate whether the effects of an in vitro IL-1β treatment may be reduced, in the presence and absence of mechanical stretch. Both P4 treatment alone, as well as P4 +F treatment reduced IL-1β-driven expression. However, stretch-induced changes in expression could not be reduced through P4 treatment, alone or in combination with forskolin. P4 maintained its capacity for reducing IL-1β driven COX-2 mRNA expression in the absence of GR, whilst overexpressing PR isoforms enhanced P4-driven action.

description: Black holes are normally and naturally associated to the end-point of gravitational collapse. Yet, alternatives have been proposed and a particularly interesting one is that of gravitational condensate stars, or gravastars. We here revisit the gravastar model and increase the degree of speculation by considering new solutions that are inspired by the original model of gravastars with anisotropic pressure, but also offer surprising new features. In particular, we show that it is possible to nest two gravastars into each other and obtain a new solution of the Einstein equations. Since each gravastar essentially behaves as a distinct self-gravitating equilibrium, a large and rich space of parameters exists for the construction of nested gravastars. In addition, we show that these nested-gravastar solutions can be extended to an arbitrarily large number of shells, with a prescription specified in terms of simple recursive relations. Although these ultra-compact objects are admittedly very exotic, some of the solutions found, provide an interesting alternative to a black hole by having a singularity-free origin, a full matter interior, a time-like matter surface, and a compactness $\mathcal{C}\to (1/2)^{-}$.

Development of a potential panel code for unsteady modelling of 2D airfoils in practical applications of large wind turbines
Creators: name: Gonzalez Salcedo, Alvaro
Publisher: name: Imperial College London
Year: 2018

description: The present work is an effort to improve airfoil modelling in wind energy applications, specifically for large wind turbine blades. A new model based on inviscid panel methods with a free vortex wake is proposed for the aerodynamic representation of deforming and moving airfoils in a wide range of operating conditions. Large rotors (above 5MW) operate in a challenging environment in terms of complex inflow conditions and dynamics of the wind turbine. The consequence for the blade sections is a significant variation of the local inflow, leading to unsteady conditions which can largely affect the loads. In order to consider this scenario, the proposed modelling strategy takes into account not only attached flow and static conditions, but also unsteady conditions with flow separation and dynamic stall, for which the present state of the art shows limitations. Some engineering concepts have been included in the formulation in order to account for the effect of the complex conditions. The present model has been implemented in an aerodynamic tool named AdaptFoil2D and an extensive validation has been carried out in order to assess the performance and the suitability of the new model. First, the results of AdaptFoil2D have been compared with experimental data of a cylinder in different flow regimes in order to validate the effect of the flow separation location. Later, static and dynamic experimental tests of the S809 and NACA0015 have been used in the validation of the model for attached and separated flow including dynamic stall. In addition, experimental tests for a NACA64418 with a TE flap have been also used in order to test the ability of the model to deal with changing geometries for active control purposes. Apart from the validation, practical investigations performed with AdaptFoil2D and related to TE flaps for load reduction have been included. The proposed model has demonstrated good performance in the estimation of the aerodynamic loads together with the reasonable computational cost associated to the inviscid approach in comparison to higher fidelity tools.

description: Settling Kahn's conjecture (2001), we prove the following upper bound on the number $i(G)$ of independent sets in a graph $G$ without isolated vertices: \[ i(G) \le \prod_{uv \in E(G)} i(K_{d_u,d_v})^{1/(d_u d_v)}, \] where $d_u$ is the degree of vertex $u$ in $G$. Equality occurs when $G$ is a disjoint union of complete bipartite graphs. The inequality was previously proved for regular graphs by Kahn and Zhao. We also prove an analogous tight lower bound: \[ i(G) \ge \prod_{v \in V(G)} i(K_{d_v+1})^{1/(d_v + 1)}, \] where equality occurs for $G$ a disjoint union of cliques. More generally, we prove bounds on the weighted versions of these quantities, i.e., the independent set polynomial, or equivalently the partition function of the hard-core model with a given fugacity on a graph.

The process starts at $t=0$ from a specified point $x=L$. We show that $P(A)$ obeys exact scaling relation $$ P(A) = \frac{D^\frac{1}{2H}}{L^{1+\frac{1}{H}}}\,Φ_H\left(\frac{D^\frac{1}{2H} A}{L^{1+\frac{1}{H}}}\right)\,, $$ where $0

Rescue of murine gammaretroviruses in human cells
Creators: name: Kakisi, Ourania
Publisher: name: Imperial College London

description: Murine leukaemia viruses (MLVs) are simple γ-retroviruses of mice that are endogenous to the mouse genome, with several being replication-competent. In 2006, a research group using virus arrays, identified a novel MLV recombinant, XMRV, in human prostate cancer (PCa) tissue and cell lines. The virus appeared to infect and replicate efficiently in human cells. Disease associations with PCa and chronic fatigue syndrome caused a worldwide concern over the presence of XMRV in the human blood supply and patient populations. The final conclusions settled in 2011, and XMRV was widely accepted as a result of contamination in patient samples while its rescue was proven directly due to the propagation of the human cancer cell lines in nude mice in vivo. The re-emerged perception of the ability of MLVs to recombine and form novel recombinants that can infect human cells propelled the need of investigation in all cases where mouse and human cells are placed in contact for biotechnology applications in vitro, such as for the expansion of human epidermal primary stem cells prior human transplantation. We first sought to screen a variety of mouse embryonic feeder (MEF) cells that are used in human stem cell culture, for the presence of replication-competent retroviruses. To this aim, we developed a tool case of molecular assays to detect MLVs and their products and then tested various MEFs with known endogenous virus activators. We identified one stably expressed ecotropic MLV retrovirus in a CF1-MEF cell line and characterised it with molecular and infectivity assays, as well as next generation sequencing (NGS). Following, we co-cultivated human corneal stem cells with the CF1-MEF cells to test the ability of the CF1-related virus to cause human cell infection and used integration splinkerette PCR and NGS to detect possible integration site sequences in the human stem cells. In all, this study provides with a comprehensive up to date assessment over the risk of transmission of MLV viruses onto human stem cells for conditions that are comparable to the protocols used in human eye cell transplantation. We conclude that the infection of stem cells is confirmed possible by xenotropic MLVs as demonstrated for limbal eye stem cells and XMRV, but unlikely as expected for the ecotropic CF1 cell-derived virus; the possibility of recombination in mouse feeders however, cannot be excluded during prolonged co-cultivations.

description: The first example of a quantum group was introduced by P.~Kulish and N.~Reshetikhin. In their paper "Quantum linear problem for the sine-Gordon equation and higher representations" published in Zap. Nauchn. Sem. LOMI, 1981, Volume 101 (English version: Journal of Soviet Mathematics, 1983, 23:4), they found a new algebra which was later called $U_q (sl(2))$. Their example was developed independently by V.~Drinfeld and M.~Jimbo, which resulted in the general notion of quantum group. Recently, the so-called Belavin-Drinfeld cohomologies (twisted and untwisted) have been introduced in the literature to study and classify certain families of quantum groups and Lie bialgebras. Later, the last two authors interpreted non-twisted Belavin-Drinfeld cohomologies in terms of non-abelian Galois cohomology $H^1(\mathbb{F}, \mathbf{H})$ for a suitable algebraic $\mathbb{F}$-group $\mathbf{H}$. Here $\mathbb{F}$ is an arbitrary field of zero characteristic. The untwisted case is thus fully understood in terms of Galois cohomology. The twisted case has only been studied using Galois cohomology for the so-called ("standard") Drinfeld-Jimbo structure. The aim of the present paper is to extend these results to all twisted Belavin-Drinfeld cohomologies and thus, to present classification of quantum groups in terms of Galois cohomologies and orders. Our results show that there exist yet unknown quantum groups for Lie algebras of the types $A_n, D_{2n+1}, E_6$.

description: The minimal Universal Extra Dimension scenario is highly constrained owing to opposing constraints from the observed relic density on the one hand, and the non-observation of new states at the LHC on the other. Simple extensions in five-dimensions can only postpone the inevitable. Here, we propose a six-dimensional alternative with the key feature being that the SM quarks and leptons are localized on orthogonal directions whereas gauge bosons traverse the entire bulk. Several different realizations of electroweak symmetry breaking are possible, while maintaining agreement with low energy observables. This model is not only consistent with all the current constraints opposing the minimal Universal Extra Dimension scenario but also allows for a multi-TeV dark matter particle without the need for any fine-tuning. In addition, it promises a plethora of new signatures at the LHC and other future experiments.
