description: The topology of Stein surfaces and contact 3-manifolds is studied by means of handle decompositions. A simple characterization of homeomorphism types of Stein surfaces is obtained --- they correspond to open handlebodies with all handles of index lessthan or = 2. An uncountable collection of exotic R^4's is shown to admit Stein structures. New invariants of contact 3-manifolds are produced, including a complete (and computable) set of invariants for determining the homotopy class of a 2-plane field on a 3-manifold. These invariants are applicable to Seiberg-Witten theory. Several families of oriented 3-manifolds are examined, namely the Seifert fibered spaces and all surgeries on various links in S^3, and in each case it is seen that ``most'' members of the family are the oriented boundaries of Stein surfaces.

description: Stick graphs are intersection graphs of horizontal and vertical line segments that all touch a line of slope -1 and lie above this line. De Luca et al. [GD'18] considered the recognition problem of stick graphs when no order is given (STICK), when the order of either one of the two sets is given (STICK_A), and when the order of both sets is given (STICK_AB). They showed how to solve STICK_AB efficiently. In this paper, we improve the running time of their algorithm, and we solve STICK_A efficiently. Further, we consider variants of these problems where the lengths of the sticks are given as input. We show that these variants of STICK, STICK_A, and STICK_AB are all NP-complete. On the positive side, we give an efficient solution for STICK_AB with fixed stick lengths if there are no isolated vertices.
Pesca Ilegal en México: Soluciones desde la Política Pesquera

description: En este documento, Oceana analiza las acciones del Estado mexicano en materia de pesca ilegal. Compara dos periodos el primero de 2009-2014, cuando la Auditoría Superior de la Federación evaluó la política pesquera, y el segundo dentro de la actual administración de 2018-2023. De este análisis, Oceana revela que las retenciones de producto pesquero por pesca ilegal cayeron 75% y las personas detenidas por esta actividad disminuyeron 95%. 

El estudio también señala que, aproximadamente, 22% de la pesca en México se “lava”, es decir, entra al mercado legal pero su captura sucedió en algún supuesto de ilegalidad. La organización analizó los avisos de arribo de diez pesquerías de 2000 a 2022 y encontró que en algunos casos se reportaron especies que estaban en periodo de veda, fuera de su zona de distribución natural, no contaban con permiso para su captura comercial, ni se identificaron como pesca incidental o se usaron artes de pesca no autorizados, entre otros.

A partir de esta información, Oceana elaboró una serie de propuestas para atender la pesca ilegal desde la política pública, a fin de atender seis tipos de pesca ilegal que más dañan a los mares y a la gente.

description: In the semiclassical approximation in which the electric charges of scalar particles are described by Grassmann variables ($Q_i^2=0, Q_iQ_j\ne 0$), it is possible to re-express the Lienard-Wiechert potentials and electric fields in the radiation gauge as phase space functions, because the difference among retarded, advanced, and symmetric Green functions is of order Q_i^2. By working in the rest-frame instant form of dynamics, the elimination of the electromagnetic degrees of freedom by means of suitable second classs contraints leads to the identification of the Lienard-Wiechert reduced phase space containing only N charged particles with mutual action-at-a-distance vector and scalar potentials. A Darboux canonical basis of the reduced phase space is found. This allows one to re-express the potentials for arbitrary N as a unique effective scalar potential containing the Coulomb potential and the complete Darwin one, whose 1/c^2 component agrees for with the known expression. The effective potential gives the classical analogue of all static and non-static effects of the one-photon exchange Feynman diagram of scalar electrodynamics.

War in literature

description: This dissertation offers readings of novels by Pierre Guyotat, Georges Perec, Patrick Modiano and other lesser-known French authors of the twentieth and twenty-first century, analyzing the representation of the “appelés d’Algérie,” the last citizens of France to be mobilized in a wartime draft. Dating back to the Third Republic, military service played a key role in turning both metropolitan and colonial populations into Frenchmen, though clearly not under the same conditions or in the same way. A historically informed account of military service’s role in citizenship formation can provide a useful analytic frame for clarifying literary engagements with contemporary French “identity-talk,” i.e. political and discursive deployments of identity and identity politics, as well as debates around laïcité, universalist assimilationism, and “communautarisme.” In early literary responses to the Algerian War, the character of the conscript serves to criticize the rising tide of consumerism and Americanization in postwar France. In novels by Daniel Anselme and René-Nicolas Ehni, draftees participate in a homosocial republicanism in which “fraternité” trumps both atomized individualism and the normative heterosexual couple, a locus of consumption. In novels by Perec and Modiano, resistance to conscription enables a critique of universalist citizenship, as the figure of the insubordinate or ambivalent conscript provides an opportunity to reckon with Jewish identity and French anti-Semitism. My analysis addresses the unequal and uneven distribution of political rights based on “identity” factors as well as the asymmetrical deployment of the term “communautarisme.” Certain of Guyotat’s texts are perceived to respond politically and aesthetically to the Algerian War, even though they refuse the conventions of realism, verisimilitude, and even representation. Using Foucault to read Guyotat, my analysis of his work provides an opportunity to address twentieth-century French debates concerning engaged and autonomous art, as well as the relationship of radical politics to radical form. I turn in my last chapter to recent novels by the prize-wining French novelists Alexis Jenni, Laurent Mauvignier, Jérôme Ferrari, and Alice Ferney. Set in part during the Algerian War, these novels draw explicit parallels between colonial violence and race-based violence in France today. These rhetorical parallels can obscure historical contingency and complexity, such as the evolving construction of the concept of “race.” Likewise, these novels contrast a virile, homogenous military and an effeminate, fractured republic and can be read as parables for the rise of the Front National in contemporary France. My analysis shows how these works can both participate in and critique particular racialized and gendered views of the French republic.
Carbon Finance Opportunities in Transportation and Clean Development Mechanism in Developing Countries–Examining The Interplay Of Investment, Emission Reduction, and Carbon Credit Revenue

description: The Clean Development Mechanism (CDM), established under the 1997 Kyoto Protocol and overseen by the United Nations Framework Convention on Climate Change (UNFCCC), provides a funding mechanism for Greenhouse Gas (GHG) reduction projects in developing countries. Despite the logical relationship with GHG, the transport sector represents a small percentage of projects approved for CDM financing, possibly because of its complex and lengthy implementation process as well as the general large scale cost. In an attempt to examine CDM’s practical applicability as a financing tool for the transport sector, this study will focus on CDM’s financial contributions to select BRT projects: Bogota’s (Colombia) TransMilenio and Chongqing (China) BRT. This study hypothesizes that the CDM financing in these BRT projects must be significant in covering the projects’ operating deficits. The study’s findings indicate that in the case of TransMilenio, while the CDM financing was not a significant contributor to the total cost, it guaranteed access to cheaper financing with low interest rate. BRT Chongqing, on the other hand, has shown to correlate to the hypothesis in so far as the CDM earnings were available. The study concludes that CDM financing has limited and marginal impact for the project completion and direct costs. However, its practical applicability rests in mitigating the project’s financial risk. CDM’s limitation remains in the market-driven nature of the Certified Emission Reduction (CER) price and other fundamental issues in the mechanism itself.

description: To sustain future population and economic growth, the global energy supply is expected to increase by 60% by 2040, but the associated CO₂ emissions are a major concern. Converting CO2 into a commodity through a CO₂-neutral process has the potential to create a sustainable carbon energy economy; however, the high stability of CO₂ requires the discovery of active, selective and stable catalysts.
      To initially probe the performance of catalysts for CO₂ reduction, CO₂ is activated with H₂, which produces CO and CH₄ as the primary products.  For this study, CO is desired for its ability to be used in the Fischer-Tropsch process, while CH₄ is undesired because of its low volumetric energy density and abundance. Precious bimetallic catalysts synthesized on a reducible support (CeO₂) show higher activity than on an irreducible support (γ-Al₂O₃) and the selectivity, represented as CO:CH₄ ratio, is correlated to electronic properties of the supported catalysts with the surface d-band center value of the metal component.
      Because the high cost of precious metals is unsuitable for a large-scale CO₂ conversion process, further catalyst development for CO₂ reduction focuses on active, selective and low-cost materials. Molybdenum carbide (Mo₂C) outperforms precious bimetallic catalysts and is highly active and selective for CO₂ conversion to CO. These results are further extended to other transition metal carbides (TMCs), which are found to be a class of promising catalysts and their activity is correlated with oxygen binding energy (OBE) and reducibility as shown by density functional theory (DFT) calculations and in-situ measurements. Because TMCs are made from much more abundant elements than precious metals, the catalysts can be manufactured at a much lower cost, which is critical for achieving a substantial reduction of CO₂ levels.
      In the aforementioned examples, sustainable CO₂ reduction requires renewable H₂, 95% of which is currently produced from hydrocarbon based-feedstocks, resulting in CO₂ emissions as a byproduct. Alternatively, CO₂ can be reduced with ethane from shale gas, which produces either synthesis gas (CO + H₂) or ethylene with high selectivity. Pt/CeO₂ is a promising catalyst to produce synthesis gas, while Mo₂C based materials preserve the C-C bond of ethane to produce ethylene. Ethylene and higher olefins are desirable for their high demand as commodity chemicals; therefore, future studies into CO₂ reduction must identify new low-cost materials that are active and stable with higher selectivity toward the production of light olefins.

description: In order to account for competition and interplay of localized and itinerant magnetic behaviour in correlated many body systems with complex spectra the various types of spin-fermion models have been considered in the context of the Irreducible Green's Functions (IGF) approach. Examples are generalized d-f model and Kondo-Heisenberg model. The calculations of the quasiparticle excitation spectra with damping for these models has been performed in the framework of the equation- of-motion method for two-time temperature Green's Functions within a non-perturbative approach. A unified scheme for the construction of Generalized Mean Fields (elastic scattering corrections) and self-energy (inelastic scattering) in terms of the Dyson equation has been generalized in order to include the presence of the two interacting subsystems of localized spins and itinerant electrons. A general procedure is given to obtain the quasiparticle damping in a self-consistent way. This approach gives the complete and compact description of quasiparticles and show the flexibility and richness of the generalized spin-fermion model concept.

In the holographic setup, cosmic evolution is mapped to inverse renormalization group (RG) flow of the dual QFT, and the resolution of the puzzles relies on properties of the RG flow.

description: Regulatory Impact Assessment (RIA) - understood as the formalised analytical activities initiated or carried out by central government administrations when designing specific policy instruments - is currently receiving high levels of political attention. It is seen as a tool to improve regulatory quality and to promote cross-cutting objectives such as sustainable development. Often conceived as an economic analysis of costs and benefits, RIA tends to be depicted as ‘neutral’ assessment process that informs decision makers about ‘facts’. This does not explain, of course, why RIA often becomes an arena for political conflict involving both government departments and stakeholders. Based on empirical research on the design and practical application of RIA across the European Union, this paper explores the relationship between RIA, policy-making and politics. The aim is to shed light on what knowledge is produced, how it is used by different actors and what role it plays in decision-making. Based on this analysis, we explore to what extent and under what conditions RIA can serve as a tool for more evidence-based and sustainability-oriented policy-making processes.

description: Within the framework of the modified potential cluster model with a classification of orbital states according to Young diagrams, the possibility of describing experimental data for total cross sections of the neutron radiative capture on 11B to the ground state of 12B at energies of 10 meV (1 meV = 10-3 eV) to 7 MeV was considered. It was shown that, taking into account only the E1 transition from the S state of the n11B scattering to the ground state of 12B, it is quite possible to explain the magnitude of the known experimental cross sections at energies of 25.3 meV to 70 keV. Furthermore, on the basis of the total cross sections of 10 meV to 7 MeV, but excluding resonances above 5 MeV, the reaction rate is calculated in the temperature range of 0.01 to 10.0 T9. It is shown that the inclusion of low-lying resonance states makes a significant contribution to the reaction rate, starting already with temperatures of 0.2-0.3 T9.

description: α-Glucosidase, an enzyme involved in post-prandial hyperglycaemia, was used as a target to study the effect of compound(s) isolated from Goniothalamus wynaadensis and its isoxazoline derivatives. Among thirteen compounds screened, compounds 1, 3a and 3j exhibited significant inhibition with IC50 values of 63.42, 61.36 and 58.89 µg/mL, respectively, outperforming acarbose (71.72 µg/mL). Kinetic studies revealed competitive binding for compound 1 and uncompetitive/non-competitive binding for 3a and 3j. Fluorescence quenching showed a linear relationship between I0/I at different inhibitor concentrations. The binding sites in α-glucosidase were ≤ 1. The binding constants 3a (0.7307) > 3j (0.6563) > 1 (0.5415) displayed strong interactions. Docking study revealed binding affinities; 3j (–8.9) > 3a (–7.7) > 1 (–7), and acarbose, 1, 3a and 3j had ARG-312, PHE-157 interactions in common to α-glucosidase. The toxicity profile showed compounds fell in classes IV and V. Overall, the results indicate that compounds 1, 3a and 3j are effective against α-glucosidase.

description: This thesis describes a detection system for single molecules based on individual single-walled carbon nanotube field-effect sensors. The sensitivity, spatial confinement and transducer gain of the sensor is derived from a conductance controlled electrochemically created defect, which is also chemically reactive. An automated microfluidic system is designed to enable long and stable measurements of the carbon nanotube device in aqueous environment with temperature control of ±0.1°C. A probe DNA can be covalently attached to the defect through an amide bond and the conductance is modulated when a target DNA binds to the probe. As a result, the conductance shows a traditional random telegraph signal and fluctuates between a hybridized and melted state. By monitoring the conductance as a function of temperature, the kinetics and thermodynamics can be extracted, which are comparable to previous fluorescent correlation spectroscopy studies using optical fluorescent resonant energy transfer. By studying the fluctuation amplitude as a function of charge proximity, buffer concentration and solution potential, it is shown that the sensor is based on a field-effect. The sensor has a temporal resolution of 200 μs and a signal to noise ratio of 3-8 when continuously measuring for 30 seconds. By further reducing the parasitics, the sensor has the capabilities to detect biomolecule kinetics down to microsecond resolution, which could make it an attractive tool for single-molecule experiments with fast kinetics.

description: We consider a generalisation of the vicious walker problem in which N random walkers in R^d are grouped into p families. Using field-theoretic renormalisation group methods we calculate the asymptotic behaviour of the probability that no pairs of walkers from different families have met up to time t. For d>2, this is constant, but for d<2 it decays as a power t^(-alpha), which we compute to O(epsilon^2) in an expansion in epsilon=2-d. The second order term depends on the ratios of the diffusivities of the different families. In two dimensions, we find a logarithmic decay (ln t)^(-alpha'), and compute alpha' exactly.

Most strikingly, the region of spacetime near the event horizon stretches into an infinitely long throat and displays an emergent conformal symmetry. Understanding dynamics in this NHEK (Near-Horizon Extreme Kerr) geometry is necessary for connecting theory to upcoming astronomical observations of high-spin black holes. We review essential properties of NHEK and its relationship to the rapidly rotating Kerr black hole. We then completely solve the geodesic equation in the NHEK region and describe how the resulting trajectories transform under the action of its enhanced symmetries. In the process, we derive explicit expressions for the angular integrals appearing in the Kerr geodesic equation and obtain a useful formula, valid at arbitrary spin, for a particle's polar angle in terms of its radial motion. These results will aid in the analytic computation of astrophysical observables relevant to ongoing and future experiments.

description: In the paper we begin a description of functional methods of quantum field theory for systems of interacting q-particles. These particles obey exotic statistics and are the q-generalization of the colored particles which appear in many problems of condensed matter physics, magnetism and quantum optics. Motivated by the general ideas of standard field theory we prove the q-functional analogues of Hori's formulation of Wick's theorems for the different ordered q-particle creation and annihilation operators. The formulae have the same formal expressions as fermionic and bosonic ones but differ by a nature of fields. This allows us to derive the perturbation series for the theory and develop analogues of standard quantum field theory constructions in q-functional form.

Spectral and transport properties of a $\mathcal{PT}$-symmetric tight-binding chain with gain and loss

description: We derive a continuity equation to study transport properties in a $\mathcal{PT}$-symmetric tight-binding chain with gain and loss in symmetric configurations. This allows us to identify the density fluxes in the system, and to define a transport coefficient to characterize the efficiency of transport of each state. These quantities are studied explicitly using analytical expressions for the eigenvalues and eigenvectors of the system. We find that in states with broken $\mathcal{PT}$-symmetry, transport is inefficient, in the sense that either inflow exceeds outflow and density accumulates within the system, or outflow exceeds inflow, and the system becomes depleted. We also report the appearance of two subsets of interesting eigenstates whose eigenvalues are independent on the strength of the coupling to gain and loss. We call these opaque and transparent states. Opaque states are decoupled from the contacts and there is no transport; transparent states exhibit always efficient transport. Interestingly, the appearance of such eigenstates is connected with the divisors of the length of the system plus one and the position of the contacts. Thus the number of opaque and transparent states varies very irregularly.

description: Some physical properties of bcc Fe/V and Fe/Co (001) superlattices are reviewed. The dependence of the magnetic anisotropy on the in-plane strain introduced by the lattice mismatch between Fe and V is measured and compared to a theoretical derivation. The dependence of the magnetic anisotropy (and saturation magnetisation) on the layer thickness ratio Fe/Co is measured and a value for the anisotropy of bcc Co is derived from extrapolation. The interlayer exchange coupling of Fe/V superlattices is studied as a function of the layer thickness V (constant Fe thickness) and layer thickness of Fe (constant V thickness). A region of antiferromagnetic coupling and GMR is found for V thicknesses 12-14 monolayers. However, surprisingly, a 'cutoff' of the antiferromagnetic coupling and GMR is found when the iron layer thickness exceeds about 10 monolayers.

description: To any symmetry of the Cartan matrix of a Generalized Kac-Moody (GKM) algebra we associate a family of automorphisms of the algebra which act in a natural way on the modules of the GKM algebra. We introduce the twining character of a module which is obtained by inserting the action of such an automorphism into the trace that appears in the ordinary character. Twining characters of integrable highest weight modules and Verma modules satisfy a character formula which involves a certain subgroup of the Weyl group. This subgroup is shown to be the Weyl group of another GKM algebra, called the orbit Lie algebra, and hence the twining characters coincide with ordinary characters of the orbit Lie algebra.

description: A line bundle with a base-point-free multiple is called semiample. I give a cohomological characterization of semiample line bundles. The result is a common generalization of the Fujita-Zariski criterion for semiampleness and the Grothendieck-Serre characterization of ampleness. Applying the Fujita-Zariski Theorem, I characterize contractible curves in 1-dimensional families.

description: We show how to implement a Rydberg-atom quantum simulator to study the non-equilibrium dynamics of an Abelian (1+1)-D lattice gauge theory. The implementation locally codifies the degrees of freedom of a $\mathbf{Z}_3$ gauge field, once the matter field is integrated out by means of the Gauss' local symmetries. The quantum simulator scheme is based on current available technology and scalable to considerable lattice sizes. It allows, within experimentally reachable regimes, to explore different string dynamics and to infer information about the Schwinger $U(1)$ model.

description: In this thesis, we address the black-box nature of deep learning models for molecular toxicity prediction as well as propose methods for aggregating various chemical features to have an improved accuracy. An ideal toxicity prediction model is characterized with high accuracy, capable of handling descriptors/features diversity, ease of training and interpretability. Considering these attributes of an ideal model, in the first quarter of this thesis we present a novel hybrid framework based on decision trees (DT) and shallow neural networks (SNN). This method paves a path to feature interpretability while enhancing the accuracy by selecting only the relevant features for model training. Using this approach, the run-time complexity of developed toxicity model is substantially reduced. The idea is to create a contextual adaptation of the models by hybridizing the decisions trees to enhance the features interpretability and accuracy both. In the later quarters of this thesis, we argue for the idea of effective aggregation of chemical knowledge about molecules in toxicity prediction. Molecules are represented in various data formats such that each format has its own specific role in predicting molecular activities. We propose various deep learning ensemble approaches to effectively aggregate different chemical features information. We have applied these methods to quantitative and qualitative molecular toxicity prediction problems and have obtained new stateof- the-art accuracy improvements with respect to existing deep learning methods. Our ensembling methods also prove helpful in making the model’s prediction robust over a range of performance metrics for toxicity prediction.
