description: The RFP is a toroidal magnetic configuration in which plasmas can spontaneously transform into different self-organized states. Among various states, the QSH state has a dominant component for the magnetic field and significantly improves confinement. Many theoretical and experimental efforts have investigated the transitions among different states. This paper employs the MRxMHD model to study the properties of QSH and other states. The SPEC is used to compute MHD equilibria for the KTX. The toroidal volume of KTX is partitioned into two subvolumes by an internal transport barrier. The geometry of this barrier is adjusted to achieve force balance across the interface, ensuring that the plasma in each subvolume is force-free and that magnetic helicity is conserved. By varying the parameters, we generate distinct self-organized states in KTX. Our findings highlight the crucial role of magnetic helicity in shaping these states. In states with low magnetic helicity in both subvolumes, the plasma exhibits axisymmetric behavior. With increasing core helicity, the plasma gradually transforms from an axisymmetric state to a double-axis helical state and finally to a single-helical-axis state. Elevated core magnetic helicity leads to a more pronounced dominant mode of the boundary magnetic field and a reduced core magnetic shear. This is consistent with previous experimental and numerical results in other RFP devices. We find a linear relationship between the plasma current and helicity in different self-organized states. Our findings suggest that KTX may enter the QSH state when the toroidal current reaches 0.72 MA. This study demonstrates that the stellarator equilibrium code SPEC unveils crucial RFP equilibrium properties, rendering it applicable to a broad range of RFP devices and other toroidal configurations.
Analysis of the CD4+ T cell immune response to Anthrax Lethal Factor
Creators: name: Ascough, Stephanie
Publisher: name: Imperial College London
Year: 2012

description: The Gram-positive bacterium Bacillus anthracis is the causative agent of the potentially fatal illness, anthrax. A major determinant of B. anthracis pathogenicity is a binary toxin composed of Protective Antigen (PA) and one of two subunits; Lethal Factor (LF) or Edema Factor (EF). Translocation by PA into the host cell cytosol allows LF, which is a zinc metalloprotease, to inactivate the mitogen-activated protein kinase (MAPK) pathway. The expected consequences for the immune response include subversion of antigen presentation and T cell priming. In contrast to this, long term CD4+ T cell responses to LF were identified following natural human anthrax infection and vaccination, indicating that this toxin component is a principle B. anthracis antigen which may confer protective immunity. It has been observed that polymorphism in the HLA class II alleles at the DR and DQ loci affects susceptibilty to infectious disease outcome. In order to map the human response within a defined genetic background, transgenic mice expressing individual HLA heterodimers in the absence of endogenous MHC class II were utilised. HLA-DR1, HLA-DR15, HLA-DR4, HLA-DQ8 and HLA-DQ6 (the latter generated as part of this project) transgenic mice were compared in terms of response magnitude to LF and HLA expression levels. This was correlated with survival following live anthrax challenge. Immunodominant epitopes within LF were elucidated for all HLA-transgenic lines. Immunogenicity in the transgenic model was shown to be primarily restricted to epitopes from domains II and IV. Dominant epitopes, which were common to all HLA types, were identified in domain II. HLA-DR specific epitopes were also identified. T cell responses to cryptic epitopes, revealed following immunisation with the individual peptides, were compared to the immunodominant epitope hierarchy. A peptide epitope of LF was identified with a strong relative binding affinity for HLA-DR15, making it a candidate therapeutic for ‘MHC blockade’ strategies. This epitope was tested for therapeutic blockade in a humanised transgenic mouse model which develops spontaneous paralysis with central nervous system (CNS) pathology similar to human multiple sclerosis (MS). Disease is characterised by an autoimmune response to a DR15 restricted epitope of myelin basic protein (MBP). The LF peptide was found to prevent induction of antigen-specific T cell responses, presumably by HLA class II, reducing the inflammatory response to self-peptide both in vitro and in vivo.

description: We show that the doubly charged scalar from the $SU(2)_R$-triplet Higgs field in the Left-Right Symmetric Model has its mass governed by a hidden symmetry so that its value can be much lower than the $SU(2)_R$ breaking scale. This makes it a long-lived particle while being consistent with all existing theoretical and experimental constraints. Such long-lived doubly charged scalars have the potential to trigger catalyzed fusion processes in light nuclei, which may have important applications for energy production. We show that it could also bear consequences on the excess of large ionization energy loss ($dE/dx$) recently observed in collider experiments.

description: Nested code pairs play a crucial role in the construction of ramp secret sharing schemes [Kurihara et al. 2012] and in the CSS construction of quantum codes [Ketkar et al. 2006]. The important parameters are (1) the codimension, (2) the relative minimum distance of the codes, and (3) the relative minimum distance of the dual set of codes. Given values for two of them, one aims at finding a set of nested codes having parameters with these values and with the remaining parameter being as large as possible. In this work we study nested codes from the Hermitian curve. For not too small codimension, we present improved constructions and provide closed formula estimates on their performance. For small codimension we show how to choose pairs of one-point algebraic geometric codes in such a way that one of the relative minimum distances is larger than the corresponding non-relative minimum distance.

Genome wide transcriptional profiling of Neisseria meningitidis in an epithelial cell line model of human nasopharyngeal colonization
Creators: name: Hey, Ariann
Publisher: name: Imperial College London
Year: 2012

description: Neisseria meningitidis (the meningococcus) is a Gram negative diplococcus which asymptomatically colonizes the human nasopharynx in about 10%-30% of the population. In rare cases it can invade the bloodstream and cross the blood brain barrier to cause sepsis and meningitis. Serogroup B strains are the major cause of disease in the UK. To gain insight into the process of colonization, I have studied the meningococcal transcriptome in a model of human nasopharyngeal colonization. As meningococcal colonization can last for weeks to months, investigating the meningococcal transcriptome over an extended period of time offers potentially important new insights into meningococcal biology unexplored in short time-course experiments as undertaken by others. Confluent layers of a human bronchial epithelial cell line (16HBE14) were infected with a serogroup B meningococcal strain (MC58) for different time periods (4h, 24h, 96h and 21d) prior to bacterial RNA extraction. Using microarray technology, the transcriptome of host cell-associated meningococci was investigated and expression of selected genes (some previously shown to be involved in host cell interaction/colonization, and others surface expressed vaccine candidates) was validated with quantitative real time PCR. The transcription profile at late time points (24 h, 96 h and 21 d) was compared to that at 4 h to identify genes potentially involved in prolonged bacteria host-cell association. A set of seven genes (NMB034230348) was identified which was up-regulated at later time points. By use of RT-PCR the operon structure of the locus was defined: one set of four and one pair of these genes are co-transcribed. MC58 kanR insertion mutants in five of these seven genes were prepared and studied in quantitative adherence and invasion assays. An impaired adherence and reduced invasion profile compared to the wild type suggests a potential role in sustained host cell association.

description: Understanding the conditions for maintaining cooperation in groups of unrelated individuals despite the presence of non-cooperative members is a major research topic in contemporary biological, sociological, and economic theory. The $N$-person snowdrift game models the type of social dilemma where cooperative actions are costly, but there is a reward for performing them. We study this game in a scenario where players move between play groups following the casual group dynamics, where groups grow by recruiting isolates and shrink by losing individuals who then become isolates. This describes the size distribution of spontaneous human groups and also the formation of sleeping groups in monkeys. We consider three scenarios according to the probability of isolates joining a group. We find that for appropriate choices of the cost-benefit ratio of cooperation and the aggregation-disaggregation ratio in the formation of casual groups, free-riders can be completely eliminated from the population. If individuals are more attracted to large groups, we find that cooperators persist in the population even when the mean group size diverges. We also point out the remarkable similarity between the replicator equation approach to public goods games and the trait group formulation of structured demes.

description: We show that N=1, D=4 Einstein-frame supergravity is inconsistent at one loop because of an anomaly in local supersymmetry transformations. A Jacobian must be added to the Einstein-frame Lagrangian to cancel this anomaly. We show how the Jacobian arises from the super-Weyl field redefinition that takes the superspace Lagrangian to the Einstein frame. We present an explicit example which demonstrates that the Jacobian is necessary for one-loop scattering amplitudes to be frame independent.

description: Kinship verification has a number of applications such as organizing large collections of images and recognizing resemblances among humans. In this research, first, a human study is conducted to understand the capabilities of human mind and to identify the discriminatory areas of a face that facilitate kinship-cues. Utilizing the information obtained from the human study, a hierarchical Kinship Verification via Representation Learning (KVRL) framework is utilized to learn the representation of different face regions in an unsupervised manner. We propose a novel approach for feature representation termed as filtered contractive deep belief networks (fcDBN). The proposed feature representation encodes relational information present in images using filters and contractive regularization penalty. A compact representation of facial images of kin is extracted as an output from the learned model and a multi-layer neural network is utilized to verify the kin accurately. A new WVU Kinship Database is created which consists of multiple images per subject to facilitate kinship verification. The results show that the proposed deep learning framework (KVRL-fcDBN) yields stateof-the-art kinship verification accuracy on the WVU Kinship database and on four existing benchmark datasets. Further, kinship information is used as a soft biometric modality to boost the performance of face verification via product of likelihood ratio and support vector machine based approaches. Using the proposed KVRL-fcDBN framework, an improvement of over 20% is observed in the performance of face verification.
Competition between phase ordering and phase segregation in the Ti$_x$NbMoTaW and Ti$_x$VNbMoTaW refractory high-entropy alloys

description: Refractory high-entropy alloys are under consideration for applications where materials are subjected to high temperatures and levels of radiation, such as in the fusion power sector. However, at present, their scope is limited because they are highly brittle at room temperature. One suggested route to mitigate this issue is by alloying with Ti. In this theoretical study, using a computationally efficient linear-response theory based on density functional theory calculations of the electronic structure of the disordered alloys, we study the nature of atomic short-range order in these multi-component materials, as well as assessing their overall phase stability. Our analysis enables direct inference of phase transitions in addition to the extraction of an atomistic, pairwise model of the internal energy of an alloy suitable for study via, e.g. Monte Carlo simulations. Once Ti is added into either the NbMoTaW or VNbMoTaW system, we find that there is competition between chemical phase ordering and segregation. These results shed light on observed chemical inhomogeneity in experimental samples, as well as providing fundamental insight into the physics of these complex systems.

L'hommage de Pierre II seigneur de Sauve, Monsieur, du mois de mai 1226 rendu à Paris à Saint-Louis est en original dans le trésor des Chartes et enregistré en la chambre des comptes. Ce même Pierre II Bermond testa à Narbonne le 18 octobre 1254 et disposa ses terres comme si elles n'avaient pas été confisquées. Il avait plusieurs enfants et donna à Philippie, vicomtesse de Narbonne, sa dernière fille, ce qu'il avait à la ville et château de Sommières, les seigneuries de Montredon, Ville Vieille, Pouzols. Ce testament est en original au château de la Voute dont on a voulu donner que par extrait ce que je marque.

Au reste, Monsieur, ce Pierre Bermond à qui ses biens avaient été généralement confisqués avait été réduit à soixante livres de rente par ordre du roi au sénéchal de Beaucaire [fol. 120 v] Je chercherai encore sur Montredon mais étant confisqué comme les autres terres, les titres ont été déposés avec ceux de ces terres. Si Monsieur de Joubert désire encore quelque éclaircissement, soyez persuadé et lui aussi de mon respect et de l'attention à rechercher ce que peut le satisfaire. Vous me trouverez trop heureux de vous seconder un peu et de vous prouver dans une si légère occasion l'attachement et la reconnaissance avec laquelle j'ai l'honneur de vous être dévoué. Mes honneurs à Mademoiselle votre soeur. Recevez ceux de mes enfants. Dès que j'aurai trouvé le prospectus imprimé, je vous l'enverrai. Je vous remercie de tout mon coeur, Monsieur, de m'avoir donné de vos nouvelles, fâché de n'avoir pas trouvé plus de renseignements qui sont dans cette lettre qui vous donne la peine de réécrire à Monsieur de Joubert.

Je reçus ce matin votre lettre par le courrier qui m’a mis dans la peine au sujet du paquet que vous m’y annoncez. Cependant, en rentrant ce soir, j’ai trouvé ledit paquet. Je m’informerai où loge M. Escher [ ?] pour l’en remercier et lier connaissance avec lui.
J’avais expédié tout de suite l’ouvrage de Corsini pour le renvoyer et les autres ne tarderont pas à arriver.
Comme on m’annonce dans le moment une commodité pour Nîmes. Je ne vous réponds qu’en remerciement, vos commissions de Gouan et de Saint-Montant seront remplies demain. Je m’empresse à vous offrir le premier exemplaire de la Bibliothèque vétérinaire ad huc amatre rubentem. Si vous aviez quelques occasions pour Leipzig, je vous prierais d’en faire agréer un exemplaire à M. Ludwig ainsi qu’à quelques autres de vos illustres amis, auprès desquels votre recommandation me sera toujours honorable. J’envoie l’affiche de ladite brochure au sieur Gaude que je vous prie de lui faire passer.
Comme j’avais recommandé à mon frère de vous saluer à son retour, tant pour s’informer de l’état de votre santé que pour se charger du paquet de livres, je suppose que s’il arrive assez à bonne heure, il n’y manquera pas et vous pourrez lui remettre le fascicule de Boemer. Je connais d’autres ouvrages de cet auteur.
Je vous suis bien obligé de votre soin à m’informer des ouvrages qui parviennent à votre connaissance touchant la médecine vétérinaire. Celui du baron de Lind n’est qu’une réimpression.
Je n’ai point trouvé dans votre paquet la lettre de M. Roustan. Peut-être l’avait-on donné séparement et que M. Escher [ ?] aura voulu me la remettre à une autre visite. J’ai l’honneur d’être avec la plus parfaite considération,

description: We smear quenched lattice QCD ensembles with lattice volume $32^3\times 8$ by using Wilson flow. Six ensembles at temperature near the critical temperature $T_c$ corresponding to the critical inverse coupling $β_c=6.06173(49)$ are used to investigate the localization of topological charge density. If the effective smearing radius of Wilson flow is large enough, the density, size and peak of Harrington-Shepard (HS) caloron-like topological lumps of ensembles are stable when $β\leq 6.050$, but start to change significantly when $β\geq6.055$. The inverse participation ratio (IPR) of topological charge density shows similar results, it begins to increase when $β\geq 6.055$ and is stable when $β\leq 6.050$. The pseudoscalar glueball mass is extracted from the topological charge density correlator (TCDC) of ensembles at $T=1.19T_c,~\textrm{and }1.36T_c$, the masses are $1.915(98)\textrm{ GeV}$ and $1.829(123)\textrm{ GeV}$ respectively, they are consistent with results from conventional methods.

description: New and surprisingly simple representation is found for the heterotic string bosonic effective action in three dimensions in terms of complex potentials. The system is presented as a Kähler $σ$--model using complex symmetric $2\times 2$ matrix (matrix dilaton--axion) which depends linearly on three Ernst--type potentials and transforms under $U$--duality via matrix valued $SL(2,R)$. Two discrete automorphisms relating ten isometries of the target space (U--duality transformations) are found and used to generate the non--trivial Ehlers--Harrison sector by a map from the trivial gauge sector. Finite transformations are obtained in a simple form in terms of complex potentials. New solution generating technique is used to construct EMDA double--Kerr solution.

description: Behavioral cloning uses a dataset of demonstrations to learn a policy. To overcome computationally expensive training procedures and address the policy adaptation problem, we propose to use latent spaces of pre-trained foundation models to index a demonstration dataset, instantly access similar relevant experiences, and copy behavior from these situations. Actions from a selected similar situation can be performed by the agent until representations of the agent's current situation and the selected experience diverge in the latent space. Thus, we formulate our control problem as a dynamic search problem over a dataset of experts' demonstrations. We test our approach on BASALT MineRL-dataset in the latent representation of a Video Pre-Training model. We compare our model to state-of-the-art, Imitation Learning-based Minecraft agents. Our approach can effectively recover meaningful demonstrations and show human-like behavior of an agent in the Minecraft environment in a wide variety of scenarios. Experimental results reveal that performance of our search-based approach clearly wins in terms of accuracy and perceptual evaluation over learning-based models.

For the proof we use reduction formulas of Lehmann Symanzik, Zimmermann (LSZ). We prove that many photons and Yang-Mills particles GF coincide in the both theories, too.

description: This project aim at the numerical approximation of partial differential equa-tion using finite difference method. Though, the analytical approximationmethod often provide useful information concerning the character of the so-lution for critical values of the dependent variables but tends to be moredifficult to apply. This led us to employ finite difference method not for itaccuracy but for it great deal of advantage over the analytical method witharising of more complex problems which analytical method cannot find solu-tion to.This method was elaborated on boundary value elliptic, parabolic, and hy-perbolic partial differential equation and other issues that will expand ourcapabilities to address more realistic problems.

Cette thèse propose un cadre normatif sur lequel on peut se baser pour orienter une réglementation cohérente et juste de la liberté académique. Ce cadre s'appuie sur celui de la liberté d'expression qui est plus étudiée et qui s'apparente à la liberté académique. Cette thèse défend que les principes d'autonomie, de vérité, de démocratie et du tort qui guident la réglementation de la liberté d'expression devraient également guider celle de la liberté académique du professeur, malgré son caractère plus spécifique. Par ailleurs, elle montre que la prévention de l'offense dans les universités s'oppose à leurs objectifs et ne devrait pas être priorisée. Ce travail vise à permettre aux universités de construire leur réglementation délimitant la liberté académique des professeurs à partir d'un cadre normatif univoque afin que ceux-ci puissent accomplir leur mandat efficacement.

description: We study the impact of the Landau Pomeranchuk Midgal (LPM) effect on the dynamics of parton interactions in proton proton collisions at the Large Hadron Collider energies. For our investigation we utilize a microscopic kinetic theory based on the Boltzmann equation. The calculation traces the space-time evolution of the cascading partons interacting via semihard pQCD scatterings and fragmentations. We focus on the impact of the LPM effect on the production of charm quarks, since their production is exclusively governed by processes well described in our kinetic theory. The LPM effect is found to become more prominent as the collision energy rises and at central rapidities and may significantly affect the model's predicted charm distributions at low momenta.

Temperature of D3-branes off extremality

description: We discuss non-extremal rotating D3-branes. We solve the wave equation for scalars in the supergravity background of certain distributions of branes and compute the absorption coefficients. The form of these coefficients is similar to the gray-body factors associated with black-hole scattering. They are given in terms of two different temperature parameters, indicating that fields (open string modes) do not remain in thermal equilibrium as we move off extremality. This should shed some light on the origin of the disagreement between the supergravity and conformal field theory results on the free energy of a system of non-coincident D-branes.

description: We study the circumstances under which a Kaluza-Klein reduction on an n-sphere, with a massless truncation that includes all the Yang-Mills fields of SO(n+1), can be consistent at the full non-linear level. We take as the starting point a theory comprising a p-form field strength and (possibly) a dilaton, coupled to gravity in the higher dimension D. We show that aside from the previously-studied cases with (D,p)=(11,4) and (10,5) (associated with the S^4 and S^7 reductions of D=11 supergravity, and the S^5 reduction of type IIB supergravity), the only other possibilities that allow consistent reductions are for p=2, reduced on S^2, and for p=3, reduced on S^3 or S^{D-3}. We construct the fully non-linear Kaluza-Klein Ansatze in all these cases. In particular, we obtain D=3, N=8, SO(8) and D=7, N=2, SO(4) gauged supergravities from S^7 and S^3 reductions of N=1 supergravity in D=10.

Development of biochar molecular models with controlled porosity

description: Biochars are an exciting class of environmental materials with a wide range of applications, including carbon storage and sequestration, soil enhancement, and pollution remediation. However, the limited knowledge of their molecular structures and compositions and the lack of comprehensive understanding of the relationship between these structures and biochars' diverse functionality, is hindering advancements in their development. In this work, we further advance the approach, first introduced by Wood et al. (2023), to constructing biochar molecular models; and now include control of microporosity (pores < 2 nm size) within the developed models. We construct biochar models representative of woody biochars which are experimentally produced at 600 -- 650 oC highest heating temperatures. Our models reproduce experimental H/C and O/C atomic ratios, percentage aromatic carbon, true density, cumulative porosity, and pore size distribution. The development of microporous biochar molecular models allows us to identify the importance of chemical structures involved in the assembly of biochar materials, and describe the relationship between these structures and obtained micropores. To facilitate other researchers integrating our approach into their work, we detail the steps taken, including the tests and reasons for each decision, in the construction of the biochar models. Furthermore, we share our developed molecular models in a format that can be easily integrated into other group's work in the form of molecular dynamics simulations.

description: In this paper, we prove the irreducibility of the monodromy action on the anti-invariant part of the vanishing cohomology on a double cover of a very general element in an ample hypersurface of a complex smooth projective variety branched at an ample divisor. As an application, we study dominant rational maps from a double cover of a very general surface $S$ of degree$\geq 7$ in ${\mathbb P}^3$ branched at a very general quadric surface to smooth projective surfaces $Z$. Our method combines the classification theory of algebraic surfaces, deformation theory, and Hodge theory.

LVC-LGMC: Joint Local and Global Motion Compensation for Learned Video Compression

description: Existing learned video compression models employ flow net or deformable convolutional networks (DCN) to estimate motion information. However, the limited receptive fields of flow net and DCN inherently direct their attentiveness towards the local contexts. Global contexts, such as large-scale motions and global correlations among frames are ignored, presenting a significant bottleneck for capturing accurate motions. To address this issue, we propose a joint local and global motion compensation module (LGMC) for leaned video coding. More specifically, we adopt flow net for local motion compensation. To capture global context, we employ the cross attention in feature domain for motion compensation. In addition, to avoid the quadratic complexity of vanilla cross attention, we divide the softmax operations in attention into two independent softmax operations, leading to linear complexity. To validate the effectiveness of our proposed LGMC, we integrate it with DCVC-TCM and obtain learned video compression with joint local and global motion compensation (LVC-LGMC). Extensive experiments demonstrate that our LVC-LGMC has significant rate-distortion performance improvements over baseline DCVC-TCM.
