description: Despite more than 2 million American cocaine users monthly, there is no approved drug for treating cocaine use disorder. Cocaine use disorder has a multifactorial aetiology, including both genetic and environmental factors. Both cocaine use and genetic variations demonstrably alter DNA methylation and gene expression in the brain in a complex manner. How these factors interact in the context of cocaine abuse in humans is unknown. We propose that we can identify potential drug targets for treating cocaine use disorders by examining genetic, epigenetic, and expression changes in the brains of individuals that abused cocaine. In this study, we identified the interaction between the epigenetics changes (DNA CpG methylation) and genetic variants (SNPs) in the HTR2A gene in the context of cocaine addiction by using brain tissue collected from individuals that overdosed on cocaine (N = 14) and healthy matched controls (N = 16). We generated DNA CpG methylation profiles in eight regions of HTR2A harbouring frequent SNPs, measuring both allelic and total methylation, and compared these methylation profiles with HTR2A mRNA expression. Furthermore, we examined the influence of common variants rs6311 and rs6313 on cocaine abuse, methylation, and gene expression. We found evidence that rs6311 regulates HTR2A methylation, consistent with earlier studies. Furthermore, the minor alleles for rs6311 and rs6313 are associated with significantly increased expression of a splice isoform in which exon 2 is truncated in both cocaine and control samples. These results reveal specific roles for HTR2A in the context of cocaine abuse, highlighting opportunities to modulate this target for treating cocaine use disorder.

description: Probability distribution for the ratio ($r$) of consecutive level spacings of the eigenvalues of a Poisson (generating regular spectra) spectrum and that of a GOE random matrix ensemble are given recently. Going beyond these, for the ensemble generated by the Hamiltonian $H_λ= (H_0+λV)/\sqrt{1+λ^2}$ interpolating Poisson ($λ=0$) and GOE ($λ\rightarrow \infty$) we have analyzed the transition curves for $\langle r\rangle$ and $\langle \tilde{r}\rangle$ as $λ$ changes from $0$ to $\infty$; $\tilde{r} = min(r,1/r)$. Here, $V$ is a GOE ensemble of real symmetric $d \times d$ matrices and $H_0$ is a diagonal matrix with a Gaussian distribution (with mean equal to zero) for the diagonal matrix elements; spectral variance generated by $H_0$ is assumed to be same as the one generated by $V$. Varying $d$ from 300 to 1000, it is shown that the transition parameter is $Λ\sim λ^2\,d$, i.e. the $\langle r\rangle$ vs $λ$ (similarly for $\langle \tilde{r}\rangle$ vs $λ$) curves for different $d$'s merge to a single curve when this is considered as a function of $Λ$. Numerically, it is also found that this transition curve generates a mapping to a $3 \times 3$ Poisson to GOE random matrix ensemble. Example for Poisson to GOE transition from a one dimensional interacting spin-1/2 chain is presented.

description: An antiferromagnetic ordering in Pb3TeCo3V2O14 takes place through formation of short range correlation regime with T* ~ 10.5 K and succession of second order phase transition at TN1 = 8.9 K and first order phase transition at TN2 = 6.3 K. An external magnetic field rapidly destroys magnetic structure at T < TN2 and influences the magnetic order at TN2 < T < TN1 resulting in complex magnetic phase diagram of Pb3TeCo3V2O14 as derived from magnetization and specific heat measurements. The first principles calculations indicate that in variance with layered crystal structure the magnetic subsystem of Pb3TeCo3V2O14 is quasi-one-dimensional and highly unusual consisting of weakly coupled triangular tubes.

We study the couplings of the Higgs boson to the $Z$ boson and $Z'$ boson predicted by the new physics models. The couplings of the $Z'$ boson to quarks can also be investigated through the $Z'q\bar{q}$ interactions. The accessible ranges of the parameter space have been searched for processes $pp\rightarrow HZX$ and $pp\rightarrow HHZX$ at the LHC with $\sqrt{s}=14$ TeV.

description: We introduce quantum field theory on quantum space-times techniques to characterize the quantum vacua as a first step towards studying black hole evaporation in spherical symmetry in loop quantum gravity and compute the Hawking radiation. We use as quantum space time the recently introduced exact solution of the quantum Einstein equations in vacuum with spherical symmetry and consider a spherically symmetric test scalar field propagating on it. The use of loop quantum gravity techniques in the background space-time naturally regularizes the matter content, solving one of the main obstacles to back reaction calculations in more traditional treatments. The discreteness of area leads to modifications of the quantum vacua, eliminating the trans-Planckian modes close to the horizon, which in turn eliminates all singularities from physical quantities, like the expectation value of the stress energy tensor. Apart from this, the Boulware, Hartle--Hawking and Unruh vacua differ little from the treatment on a classical space-time. The asymptotic modes near scri are reproduced very well. We show that the Hawking radiation can be computed, leading to an expression similar to the conventional one but with a high frequency cutoff. Since many of the conclusions concern asymptotic behavior, where the spherical mode of the field behaves in a similar way as higher multipole modes do, the results can be readily generalized to non spherically symmetric fields.

description: The phase of prestimulus oscillations at 7-10 Hz has been shown to modulate perception of briefly presented visual stimuli. Specifically, a recent combined EEG-fMRI study suggested that a prestimulus oscillation at around 7 Hz represents open and closed windows for perceptual integration by modulating connectivity between lower order occipital and higher order parietal brain regions. We here utilized brief event-related transcranial alternating current stimulation (tACS) to specifically modulate this prestimulus 7 Hz oscillation, and the synchrony between parietal and occipital brain regions. To this end we tested for a causal role of this particular prestimulus oscillation for perceptual integration. The EEG was acquired at the same time allowing us to investigate frequency specific after effects phase-locked to stimulation offset. On a behavioural level our results suggest that tACS did modulate perceptual integration, however, in an unexpected manner. On an electrophysiological level our results suggest that brief tACS does induce oscillatory entrainment, as visible in frequency specific activity phase-locked to stimulation offset. Together, our results do not strongly support a causal role of prestimulus 7 Hz oscillations for perceptual integration. However, our results suggest that brief tACS is capable of modulating oscillatory activity in a temporally sensitive manner.

description: We analyze the logical foundations of quantum mechanics (QM) by stressing non-objectivity of quantum observables which is a consequence of the absence of logical atoms in QM. We argue that the matter of quantum non-objectivity is that, on the one hand, the formalism of QM constructed as a mathematical theory is self-consistent, but, on the other hand, quantum phenomena as results of experimenter's performances are not self-consistent. This self-inconsistency is an effect of that the language of QM differs much from the language of human performances. The first is the language of a mathematical theory which uses some Aristotelian and Russellian assumptions (e.g., the assumption that there are logical atoms). The second language consists of performative propositions which are self-inconsistent only from the viewpoint of conventional mathematical theory, but they satisfy another logic which is non-Aristotelian. Hence, the representation of quantum reality in linguistic terms may be different: from a mathematical theory to a logic of performative propositions. To solve quantum self-inconsistency, we apply the formalism of non-classical self-referent logics.
Microstructure of the superior tmporal gyrus and hallucination proneness - a multi-compartment diffusion imaging study

description: Previous studies reported that the volume of the left superior temporal gyrus (STG) is reduced in patients with schizophrenia and negatively correlated with hallucination severity. Moreover, diffusion-tensor imaging studies suggested a relationship between the brain microstructure in the STG of patients and auditory hallucinations. Hallucinations are also experienced in non-patient groups. This study investigated the relationship between hallucination proneness and the brain structure of the STG. Hallucination proneness was assessed by the Launey Slade Hallucination Scale (LSHS) in 25 healthy individuals who varied in their propensity to hear voices. Brain volume and microstructure of the STG was assessed by magnetic resonance imaging (MRI). Microstructure was examined by conventional diffusion-tensor imaging as well as by neurite orientation dispersion and density imaging (NODDI). The latter decomposes diffusion-based MRI into multiple compartments that characterize the brain microstructure by its neurite complexity known as orientation dispersion (ODI) and by its neurite density (NDI). Hallucination proneness was negatively correlated with the volume and microstructure (fractional anisotropy, neurite complexity) of the left but not the right STG. The strongest relationship (r = −0.563) was observed for neurite complexity (ODI). No correlation was observed for neurite density (NDI). These findings suggest that there is a relationship between the volume and the microstructure of the left STG and hallucination proneness. Dendritic complexity (but not neurite density) is inversely related to hallucination proneness. Metrics based on multi-compartment diffusion models seem to be more sensitive for hallucination-related neural processes than conventional MRI-based metrics.

description: Let $\mathbb{N}_0$ denote the set of all non-negative integers and $\mathcal{P}(\mathbb{N}_0)$ be its power set. An integer additive set-indexer (IASI) of a graph $G$ is an injective function $f:V(G)\to \mathcal{P}(\mathbb{N}_0)$ such that the induced function $f^+:E(G) \to \mathcal{P}(\mathbb{N}_0)$ defined by $f^+ (uv) = f(u)+ f(v)$ is also injective, where $\mathbb{N}_0$ is the set of all non-negative integers. A graph $G$ which admits an IASI is called an IASI graph. An IASI of a graph $G$ is said to be an arithmetic IASI if the elements of the set-labels of all vertices and edges of $G$ are in arithmetic progressions. In this paper, we discuss about two special types of arithmetic IASIs.

description: Let D_v the difference operator and q-difference operators defined by D_ωp(x) = \frac{p(x+ω)-p(x)}ω and D_q p(x) = \frac{p(qx)-p(x)}{(q-1)x}, respectively. Let U and V be two moment regular linear functionals and let (P_n)_n and Q_n)_n be their corresponding orthogonal polynomial sequences (OPS). We discuss an inverse problem in the theory of discrete orthogonal polynomials involving the above two OPS assuming that their difference derivatives $D_ν$ of higher orders m and k (resp.) are connected by a linear algebraic structure relation such as $$ \sum_{i=0}^M a_{i,n} D_ν^m P_{n+m-i}(x) = \sum_{i=0}^N b_{i,n} D_ν^k Q_{n+k-i}(x), \quad n\geq 0, $$ where $M,N,m,k=0,1,2,... Under certain conditions, we prove that U and V are related by a rational factor ç (in the distributional sense). Moreover, when m\neq k then both U and V are D_v-semiclassical functionals. This leads us to the concept of (M,N)-D_v-coherent pair of order (m,k) extending to the discrete case several previous works. As an application we consider the OPS with respect to a certain following Sobolev-type discrete inner product.

description: We study the onset of neutron drip in high density matter in the presence of magnetic field. It has been found that for systems having only protons and electrons, in the presence of magnetic field >~ 10^{15}G, the neutronization occurs at a density which is atleast an order of magnitude higher compared to that in a nonmagnetic system. In a system with heavier ions, the effect of magnetic field, however, starts arising at a much higher field, >~ 10^{17}G. These results may have important implications in high magnetic neutron stars and white dwarfs and, in general, nuclear astrophysics when the system is embedded with high magnetic field.

description: The lensing signals involved in CMB polarization maps have already been measured with ground-based experiments such as SPTpol and POLARBEAR, and would become important as a probe of cosmological and astrophysical issues in the near future. Sizes of polarization maps from ground-based experiments are, however, limited by contamination of long wavelength modes of observational noise. To further extract the lensing signals, we explore feasibility of measuring lensing signals from a collection of small sky maps each of which is observed separately by a ground-based large telescope, i.e., lensing reconstruction from a patchwork map of large sky coverage organized from small sky patches. We show that, although the B-mode power spectrum obtained from the patchwork map is biased due to baseline uncertainty, bias on the lensing potential would be negligible if the B-mode on scales larger than the blowup scale of $1/f$ noise is removed in the lensing reconstruction. As examples of cosmological applications, we also show 1) the cross-correlations between the reconstructed lensing potential and full-sky temperature/polarization maps from satellite missions such as PLANCK and LiteBIRD, and 2) the use of the reconstructed potential for delensing B-mode polarization of LiteBIRD observation.

description: Das Ziel des Projekts besteht im Aufbau eines zentralen Dienstes für die Bereitstellung und Entwicklung von Terminologien (Terminologiedienst), der beginnend für die Anthropologie zum Einsatz kommt, aber auf weitere Wissenschaftszweige ausgedehnt und somit weiter- und wiederverwendet werden kann. Dazu soll auf bestehende Software, z.B. OLS, zurückgegriffen werden, die ebenso in der Nationalen Forschungsdaten Infrastruktur (NFDI) Initiative oder einer anderen aktuellen Initiative Verwendung findet. Insbesondere soll in Abstimmung mit den Konsortien NFDI4Health (insb. Zentralbibliothek der Medizin) und NFDI4DataScience (insb. TIB Hannover) ein Synchronisationsmodul entwickelt werden, so dass sich der Terminologiedienst mit anderen Terminologiediensten synchronisieren kann. Dagegen wird mit sächsischen Partnern (z.B. Landesamt für Archäologie und Rechtsmedizinische Institute) und mit dem aktuell in Antragstellung befindlichen Konsortium NFDI4Objects eine inhaltliche Zusammenarbeit vereinbart, die sich auf die Nachnutzung der im Terminologiedienst angebotenen Terminologien/Ontologien stützt. Dazu soll im Projekt der Sprachgebrauch der historischen Anthropologie bezogen auf die Beschreibung eines Skelettsystems terminologisch gefasst und abgebildet werden. Darauf aufbauend lassen sich ontologisch repräsentierte Phänotypen bilden, die Grundlage weiterer Fragestellungen sein können. Daraus resultiert nicht nur die Interoperabilität zwischen kooperierenden Einrichtungen in Sachsen sondern deutschland- und weltweit. Darüber hinaus kann die Terminologie direkt in verschiedenen Softwaresystemen (z.B. AnthroWorks3D [2]) zur Einordnung und Annotation von Skelett- und Knochenfunden verwendet werden. Mit dieser Software werden aktuell Knochenfunde verschiedener Gräberfelder in einem aufwändigen Verfahren in Form eines digitalen Zwillings (noch ohne ontologische Fundierung) abgebildet, annotiert und untersucht. So lassen sie sich als 3D-Modell der (forschenden) Nachwelt erhalten, da die Knochenfunde im Anschluss aus ethischen und regulatorischen Gründen wieder bestattet werden. Die aufzubauende Terminologie fördert somit die übergreifende Zusammenarbeit verschiedener Partner in der Anthropologie in Sachsen und darüber hinaus. Die Beschreibung, Klassifikation und Analyse der Knochenfunde in Ausgrabungen wird durch eine einheitliche Einordnung und Annotation unter Nutzung von Terminologien/Ontologien sowie darauf basierende Ableitung ontologisch repräsentierter Phänotypen unterstützt. Terminologien/Ontologien stellen somit eine Grundlage der Interoperabilität der Daten entsprechend der FAIR-Prinzipien dar und ermöglichen die Vergleichbarkeit, Transparenz und Nachhaltigkeit der Analyse-Ergebnisse.

description: Although in real life people frequently perform visual search together, in lab experiments this social dimension is typically left out. Here, we investigate individual, collaborative and competitive visual search with visualization of search partners’ gaze. Participants were instructed to search a grid of Gabor patches while being eye tracked. For collaboration and competition, searchers were shown in real time at which element the paired searcher was looking. To promote collaboration or competition, points were rewarded or deducted for correct or incorrect answers. Early in collaboration trials, searchers rarely fixated the same elements. Reaction times of couples were roughly halved compared with individual search, although error rates did not increase. This indicates searchers formed an efficient collaboration strategy. Overlap, the proportion of dwells that landed on hexagons that the other searcher had already looked at, was lower than expected from simulated overlap of two searchers who are blind to the behavior of their partner. The proportion of overlapping dwells correlated positively with ratings of the quality of collaboration. During competition, overlap increased earlier in time, indicating that competitors divided space less efficiently. Analysis of the entropy of the dwell locations and scan paths revealed that in the competition condition, a less fixed looking pattern was exhibited than in the collaborate and individual search conditions. We conclude that participants can efficiently search together when provided only with information about their partner’s gaze position by dividing up the search space. Competing search exhibited more random gaze patterns, potentially reflecting increased interaction between searchers in this condition.

description: We present the four-loop remainder function for six-gluon scattering with maximal helicity violation in planar N=4 super-Yang-Mills theory, as an analytic function of three dual-conformal cross ratios. The function is constructed entirely from its analytic properties, without ever inspecting any multi-loop integrand. We employ the same approach used at three loops, writing an ansatz in terms of hexagon functions, and fixing coefficients in the ansatz using the multi-Regge limit and the operator product expansion in the near-collinear limit. We express the result in terms of multiple polylogarithms, and in terms of the coproduct for the associated Hopf algebra. From the remainder function, we extract the BFKL eigenvalue at next-to-next-to-leading logarithmic accuracy (NNLLA), and the impact factor at NNNLLA. We plot the remainder function along various lines and on one surface, studying ratios of successive loop orders. As seen previously through three loops, these ratios are surprisingly constant over large regions in the space of cross ratios, and they are not far from the value expected at asymptotically large orders of perturbation theory.

description: This study investigates thermal dynamics of tropical rivers influenced by dams, focusing on the Rajang and Baleh rivers in Sarawak, Malaysia, and the Semeniyh and Sompo rivers in Peninsular Malaysia. It compares satellite and UAV-based observations to assess thermal variations downstream of dams. Results show that UAVs capture finer-scale thermal heterogeneity than satellites, with stronger correlations and higher spatial resolution. The study highlights significant thermal changes in the Rajang River due to dam operations, with altered seasonal variability. It underscores the need to integrate satellite and UAV data for effective ecological monitoring and management of thermal dynamics in tropical rivers.

description: Collective effects in the level density are not well understood, and including these effects as enhancement factors to the level density does not produce sufficiently consistent predictions of observables. Therefore, collective effects are investigated in the level density parameter instead of treating them as a final factor in the level density. A new Laplace-like formula is proposed for the energy dependence of the level density parameter, including collective effects. A significant improvement has been achieved in agreement between observed and predicted energy levels. This new model can also be used in both structure and reaction calculations of the nuclei far from stability, especially near the drip lines.

description: Recent results from direct and indirect searches for dark matter (DM) have motivated the study of particle physics models that can provide weakly interacting massive particles (WIMPs) in the mass range 1-50 GeV. Viable candidates for light WIMP DM must fulfil stringent constraints. On the one hand, the observation at the LHC of a Higgs boson with Standard Model properties set an upper bound on the coupling of light DM particles to the Higgs, thereby making it difficult to reproduce the correct relic abundance. On the other hand, the recent results from direct searches in the CDMSlite, SuperCDMS and LUX experiments have set upper constraints on the DM scattering cross section. In this paper, we investigate the viability of light right-handed sneutrino DM in the Next-to-Minimal Supersymmetric Model (NMSSM) in the light of these constraints. To this aim, we have carried out a scan in the NMSSM parameter space, imposing experimental bounds on the Higgs sector and low-energy observables, such as the muon anomalous magnetic moment and branching ratios of rare decays. We demonstrate that the enlarged Higgs sector of the NMSSM, together with the flexibility provided by the RH sneutrino parameters, make it possible to obtain viable RH sneutrino DM with a mass as light as 2 GeV. We have also considered the upper bounds on the annihilation cross section from Fermi LAT data on dwarf spheroidal galaxies, and extracted specific examples with mass in the range 8-50 GeV that could account for the apparent low-energy excess in the gamma-ray emission at the Galactic Centre. Then, we have computed the theoretical predictions for the elastic scattering cross-section of RH sneutrinos. Finally, after imposing the recent bounds from SuperCDMS and LUX, we have found a wide area of the parameter space that could be probed by future low-threshold direct detection experiments.

description: Given an integer $m\geq2$, the Hardy--Littlewood inequality (for real scalars) says that for all $2m\leq p\leq\infty$, there exists a constant $C_{m,p}% ^{\mathbb{R}}\geq1$ such that, for all continuous $m$--linear forms $A:\ell_{p}^{N}\times\cdots\times\ell_{p}^{N}\rightarrow\mathbb{R}$ and all positive integers $N$, \[ \left( \sum_{j_{1},...,j_{m}=1}^{N}\left\vert A(e_{j_{1}},...,e_{j_{m}% })\right\vert ^{\frac{2mp}{mp+p-2m}}\right) ^{\frac{mp+p-2m}{2mp}}\leq C_{m,p}^{\mathbb{R}}\left\Vert A\right\Vert . \] The limiting case $p=\infty$ is the well-known Bohnenblust--Hille inequality; the behavior of the constants $C_{m,p}^{\mathbb{R}}$ is an open problem. In this note we provide nontrivial lower bounds for these constants.

description: We propose a novel Continuation Multi Level Monte Carlo (CMLMC) algorithm for weak approximation of stochastic models. The CMLMC algorithm solves the given approximation problem for a sequence of decreasing tolerances, ending when the required error tolerance is satisfied. CMLMC assumes discretization hierarchies that are defined a priori for each level and are geometrically refined across levels. The actual choice of computational work across levels is based on parametric models for the average cost per sample and the corresponding weak and strong errors. These parameters are calibrated using Bayesian estimation, taking particular notice of the deepest levels of the discretization hierarchy, where only few realizations are available to produce the estimates. The resulting CMLMC estimator exhibits a non-trivial splitting between bias and statistical contributions. We also show the asymptotic normality of the statistical error in the MLMC estimator and justify in this way our error estimate that allows prescribing both required accuracy and confidence in the final result. Numerical results substantiate the above results and illustrate the corresponding computational savings in examples that are described in terms of differential equations either driven by random measures or with random coefficients.

description: For nanostructured interfaces between open-shell molecules and metal surfaces that involve charge transfer upon adsorption, the investigation of molecular magnetic properties is an interesting yet difficult task, because in principle different magnetic configurations with distinct properties can be found. Here, we study the magnetic properties of CuPc-Ag and CoPc-Ag interfaces, which constitute interesting test cases because charge is transferred to the initially open-shell Pc molecules upon adsorption. Using hybrid density functional theory, we examine the stability of the various magnetic configurations occurring at these nanoscale interfaces, as well as for the corresponding gas-phase anions, and compare our findings to those of previous experimental studies. For CuPc-Ag, we identify a high-spin triplet configuration as the most likely configuration at the interface, whereas for CoPc-Ag a quenching of the total magnetic moment is found. Interestingly, such quenching is consistent with two distinctly different interfacial electronic configurations. These important differences in the magnetic properties of CuPc and CoPc on Ag are rationalized by variations in the interaction of their central metal atoms with the substrate. Our work facilitates a deeper understanding of the magnetic configuration and interlinked electronic-structure properties of molecule-metal interfaces. Furthermore, it highlights the necessity of an appropriate choice of methodology in tandem with a detailed evaluation of the different emerging magnetic properties.

description: We present measurements of the inclusive production of antideuterons in $e^+e^-$ annihilation into hadrons at $\approx 10.58 \mathrm{\,Ge\kern -0.1em V}$ center-of-mass energy and in $Υ(1S,2S,3S)$ decays. The results are obtained using data collected by the BABAR detector at the PEP-II electron-positron collider. Assuming a fireball spectral shape for the emitted antideuteron momentum, we find $\mathcal{B}(Υ(1S) \to \bar{d}X) = (2.81 \pm 0.49 \mathrm{(stat)} {}^{+0.20}_{-0.24} \mathrm{(syst)})/! \times /! 10^{-5}$, $\mathcal{B}(Υ(2S) \to \bar{d}X) = (2.64 \pm 0.11 \mathrm{(stat)} {}^{+0.26}_{-0.21} \mathrm{(syst)})/! \times /! 10^{-5}$, $\mathcal{B}(Υ(3S) \to \bar{d}X) = (2.33 \pm 0.15 \mathrm{(stat)} {}^{+0.31}_{-0.28} \mathrm{(syst)})/! \times /! 10^{-5}$, and $σ(e^+e^- \to \bar{d}X) = (9.63 \pm 0.41 \mathrm{(stat)} {}^{+1.17}_{-1.01} \mathrm{(syst)}) \mbox{\,fb}$.

title: A study of Marx's method in the work of V.I. Lenin and Rosa Luxemburg
Creators: name: Padgett, Stephen
Publisher: name: University of Kent
Year: 2022

description: This theis is a study of the Marxism of V. I. Lenin and Rosa Luxemburg,in the context of the intellectual currents of Second International Marxism. A central argument is that the work of Lenin and Luxemburg contains evidence of a mode of thought uhich distinguished them from their contemporaries. The object of this thesis is to define and explore the methodology underpinning Marx's work,and to indicate the affinities between Marx's methodology and that of Lenin and Luxemburg. Whilst the work of neither Lenin nor Luxemburg was entirely free of the positivism often found in the Second International,an appreciation ofuhich is the methodology underlying certain concepts in Marx's economic and political theory is evident in their work. The abstractions uhich Marx employed in his economic work, and the nature of the laws uhich his findings indicated, were often misconstrued and deformed by the Marxists of the Second International,uho lacked the broad vision to confront the object of their enquiry in its wider significance - to grasp the broad canvas of events as they unfolded. The subjective aspects of Marx'x thought uere almost completely neglected by Marxists in this period, obscured by the militant, undeviating materialism uhich dominated their thought. In Part I of this thesis, the construction of Marx's work, the evolution of his thought and the methodological precepts which govern it are examined. Parts II and III trace the themes of Marx's method in the contributions which Lenin and Luxemburg made to debates on the questions which moved Marxists in the period. It is argued that Lenin and Luxemburg set themselves apart from their peers by their ability to excavate beneath the surface of Marx's work, to grasp the methodological nuances which it contained, and to replicate these in their own work. In short, it is argued that their mode of thought uas sympathetic to Marx's own.

description: We study N=(0,2) deformed (2,2) two-dimensional sigma models. Such heterotic models were discovered previously on the world sheet of non-Abelian strings supported by certain four-dimensional N=1 theories. We study geometric aspects and holomorphic properties of these models, and derive a number of exact expressions for the beta functions in terms of the anomalous dimensions analogous to the NSVZ beta function in four-dimensional Yang-Mills. Instanton calculus provides a straightforward method for the derivation. The anomalous dimensions are calculated up to two loops implying that one of the beta functions is explicitly known up to three loops. The fixed point in the ratio of the couplings found previously at one loop is not shifted at two loops. We also consider the N=(0,2) supercurrent supermultiplet (the so-called hypercurrent) and its anomalies, as well as the "Konishi anomaly." This gives us another method for finding exact $β$ functions. We prove that despite the chiral nature of the models under consideration quantum loops preserve isometries of the target space.
