description: La educación financiera es un saber necesario para la participación asertiva de los sujetos en la sociedad, permitiéndole tomar decisiones más conscientes frente al uso de su dinero y el de su familia. La reciente crisis a causa del virus SARS-CoV-2 y las consecuencias económicas y financieras que trajo para los hogares colombianos, nos resalta la importancia de incluir en los currículos escolares la educación financiera desde diferentes áreas, particularmente las matemáticas. En este sentido, surge este trabajo de investigación con el objetivo de desarrollar las competencias financieras en estudiantes de grado octavo del colegio técnico Industrial José Elías Puyana, para ello se diseñó un curso virtual llamado ‘El mundo de las finanzas’, en el cual se utilizaron diferentes herramientas como los son Genially, Google Classroom, YouTube entre otros, y se incluyeron elementos de gamificación, los estudiantes participaron en un contexto relacionado con un viaje y en el desarrollo de las actividades en diferentes mundos (módulos) en los cuales exploraron diversas ideas y conceptos relacionados con las finanzas y las matemáticas. Finalmente, en este trabajo se determina que el contexto de puntajes y ventajas que se ofrecen en los contextos gamificados permiten recrear actividades propias de las relaciones financieras de una manera natural y familiar para los estudiantes, de igual manera los contextos que involucran los intereses de los estudiantes y la utilidad de las ideas en su contexto cercano permiten una mayor participación de ellos y el desarrollo de sus competencias financieras.

description: We generalize the rejection-free event-chain Monte Carlo algorithm from many particle systems with pairwise interactions to systems with arbitrary three- or many-particle interactions. We introduce generalized lifting probabilities between particles and obtain a general set of equations for lifting probabilities, the solution of which guarantees maximal global balance. We validate the resulting three-particle event-chain Monte Carlo algorithms on three different systems by comparison with conventional local Monte Carlo simulations: (i) a test system of three particles with a three-particle interaction that depends on the enclosed triangle area; (ii) a hard-needle system in two dimensions, where needle interactions constitute three-particle interactions of the needle end points; (iii) a semiflexible polymer chain with a bending energy, which constitutes a three-particle interaction of neighboring chain beads. The examples demonstrate that the generalization to many-particle interactions broadens the applicability of event-chain algorithms considerably.

description: First we discuss the definition of the instantaneous current in interacting particle systems, in particular in mass-energy systems and we point out its role in the derivation of the hydrodynamics. Later we present some geometrical structures of the instantaneous current when the rates satisfy a common symmetry. These structures give some new ideas in non-gradient models and show new phenomenology in diffusive interacting particle systems. Specifically, we introduce models with vorticity and present some new perspectives on the link between the Green-Kubo's formula and the hydrodynamics of non-gradient models.

description: As a vital strategic resource, oil has an essential influence on the world economy, diplomacy and military development. Using oil trade data to dynamically monitor and warn about international trade risks is an urgent need. Based on the UN Comtrade data from 1988 to 2017, we construct unweighted and weighted global oil trade networks (OTNs). Complex network theories have some advantages in analyzing global oil trade as a system with numerous economies and complicated relationships. This paper establishes a trading-based network model for global oil trade to study the evolving efficiency, criticality and robustness of economies and the relationships between oil trade partners. The results show that for unweighted OTNs, the efficiency of oil flows gradually increases with growing complexity of the OTNs, and the weighted efficiency indicators are more capable of highlighting the impact of major events on the OTNs. The identified critical economies and trade relationships have more important strategic significance in the real market. The simulated deliberate attacks corresponding to national bankruptcy, trade blockade, and economic sanctions have a more significant impact on the robustness than random attacks. When the economies are promoting high-quality economic development, and continuously enhancing positions in the OTN, more attention needs be paid to the identified critical economies and trade relationships. To conclude, some suggestions for application are given according to the results.

description: We show how the success of deep learning could depend not only on mathematics but also on physics: although well-known mathematical theorems guarantee that neural networks can approximate arbitrary functions well, the class of functions of practical interest can frequently be approximated through "cheap learning" with exponentially fewer parameters than generic ones. We explore how properties frequently encountered in physics such as symmetry, locality, compositionality, and polynomial log-probability translate into exceptionally simple neural networks. We further argue that when the statistical process generating the data is of a certain hierarchical form prevalent in physics and machine-learning, a deep neural network can be more efficient than a shallow one. We formalize these claims using information theory and discuss the relation to the renormalization group. We prove various "no-flattening theorems" showing when efficient linear deep networks cannot be accurately approximated by shallow ones without efficiency loss, for example, we show that $n$ variables cannot be multiplied using fewer than 2^n neurons in a single hidden layer.

Quantum Fisher Information as a Predictor of Decoherence in the Preparation of Spin-Cat States for Quantum Metrology

Subjects: subject: Quantum Physics (quant-ph)

description: In its simplest form, decoherence occurs when a quantum state is entangled with a second state, but the results of measurements made on the second state are not accessible. As the second state has effectively "measured" the first, in this paper we argue that the quantum Fisher information is the relevant metric for predicting and quantifying this kind of decoherence. The quantum Fisher information is usually used to determine an upper bound on how precisely measurements on a state can be used to estimate a classical parameter, and as such it is an important resource. Quantum enhanced metrology aims to create non-classical states with large quantum Fisher information and utilise them in precision measurements. In the process of doing this it is possible for states to undergo decoherence, for instance atom-light interactions used to create coherent superpositions of atomic states may result in atom-light entanglement. Highly non-classical states, such as spin-cat states (Schrödinger cat states constructed from superpositions of collective spins) are shown to be highly susceptible to this kind of decoherence. We also investigate the required field occupation of the second state, such that this decoherence is negligible.

Thesis with publications.

The aim of this thesis was to determine the best field exercise test for use in cardiac rehabilitation for the measurement of physical fitness and functional capacity. To do this, the studies and methods followed the framework for assessing measurement properties proposed by the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) group. The most common field tests used in cardiac rehabilitation were the six-minute walk test (6MWT) and the 10 m incremental shuttle walk test (10 m ISWT). A series of three empirical studies with a total of 107 participants and a systematic review were completed. In a population of patients commencing cardiac rehabilitation, the 6MWT demonstrated a high level of systematic error and insufficient retest reliability when up to three tests were performed. The 10 m ISWT was highly reliable when both relative reliability and measurement error were assessed for both consistency and absolute agreement. Evidence supported validity for the 10 m ISWT when compared with other measures of function and the criterion, the symptom-limited exercise test. The 10 m ISWT was responsive to change over an eight-week cardiac rehabilitation program. The test showed acceptable interpretability, the minimal important change across a cardiac rehabilitation program was greater than the smallest detectable change. Support for the measurement properties and interpretability did not change when one or two tests were performed. Results were consistent with the systematic review (n equals 78 studies), which synthesised measurement properties of field exercise tests in cardiac rehabilitation. In conclusion, the 10 m ISWT was found to be the preferred field test for measurement of physical fitness and functional capacity in cardiac rehabilitation, with acceptable measurement properties when a single test is performed. A single test is suitable for ambulant low-intermediate risk patients entering low to moderate intensity cardiac rehabilitation programs.

description: Gender is one of the crosscutting and the prime importance of any development plan and intervention. Rural women play vital roles in agricultural activities to reduce poverty and food insecurity. This study focuses on gender equality in the access and control of agricultural and rural household resources by rural women. The study was conducted in Bassonawerana, Kewot, and Moretinajiru districts of Northern Shewa Zone Amhara region Ethiopia. Data were collected using individual interviews, key informant interviews, and focus group discussions. A total of 252 respondents were selected using purposive sampling, categorical, and then simple random sample selection techniques. Descriptive statistics and Harvard analysis techniques were used to assess the access, control, and utilization of agricultural and household resources in rural areas. Most of the respondents were married. 95% of the study households depend on agricultural activities of crop and livestock farming. The average family size was 5 in which 3 of them were involved in agricultural activities. The average level of education for the households was 2.5 years. Women were involved in on-farm and off-farm income-generating activities but most women had limited access to extension services and agricultural-related training. The benefits of different resources were shared by all family members equally except institutional resources. Poultry was predominantly owned by women while other livestock resources and land resources were owned by both men’s and women’s family members. Provision of women-targeted training and agricultural extension services focused on how to access and control institutional and household resources are vital to enhance their access to institutional resources and improve the production and productivity of women in the rural household and the entire community for livelihood and food security improvements.

description: Standard big bang cosmology predicts a cosmic neutrino background at $T_ν\simeq 1.95~$K. Given the current neutrino oscillation measurements, we know most neutrinos move at large, but non-relativistic, velocities. Therefore, dark matter haloes moving in the sea of primordial neutrinos form a neutrino wake behind them, which would slow them down, due to the effect of {\it dynamical friction}. In this paper, we quantify this effect for realistic haloes, in the context of the halo model of structure formation, and show that it scales as $m_ν^4$ $\times$ relative velocity, and monotonically grows with the halo mass. Galaxy redshift surveys can be sensitive to this effect (at $>3σ$ confidence level, depending on survey properties, neutrino mass and hierarchy) through redshift space distortions (RSD) of distinct galaxy populations.

description: We develop techniques to solve ill-posed inverse problems on the sphere by sparse regularisation, exploiting sparsity in both axisymmetric and directional scale-discretised wavelet space. Denoising, inpainting, and deconvolution problems, and combinations thereof, are considered as examples. Inverse problems are solved in both the analysis and synthesis settings, with a number of different sampling schemes. The most effective approach is that with the most restricted solution-space, which depends on the interplay between the adopted sampling scheme, the selection of the analysis/synthesis problem, and any weighting of the l1 norm appearing in the regularisation problem. More efficient sampling schemes on the sphere improve reconstruction fidelity by restricting the solution-space and also by improving sparsity in wavelet space. We apply the technique to denoise Planck 353 GHz observations, improving the ability to extract the structure of Galactic dust emission, which is important for studying Galactic magnetism.

description: Este trabajo tiene como propósito mostrar la noción de guerra justa defendida por Michael Walzer, desarrollada en gran medida en su libro Guerras justas e injustas. Y que actualmente es el marco conceptual bajo el cual se determina si una guerra es justa o no. Es importante tener en cuenta que la idea de guerra justa fue concebida desde tiempo atrás por pensadores como Cicerón, San Agustín de Hipona, Santo Tomas de Aquino. Así pues, con la investigación y estudio de estas sociedades o formas de ejercer la guerra como un derecho, pasando por los conceptos de ius ad bellum, ius in bello, ius post bellum, se logra mostrar las características que juega la noción de guerra justa en los últimos conflictos bélicos que ha vivido la humanidad y la sociedad actual. Y, aunque hoy este en debate si realmente una guerra puede ser justa o no, lo cierto es que Michael Walzer brinda lineamientos conceptuales bajo los cuales poder delimitar la guerra, tanto para hacerla “legitima” como un poco menos deshumanizada.

description: Nonabelian anyons offer the prospect of storing quantum information in a topological qubit protected from decoherence, with the degree of protection determined by the energy gap separating the topological vacuum from its low lying excitations. Originally proposed to occur in quantum wells in high magnetic fields, experimental systems thought to harbor nonabelian anyons range from p-wave superfluids to superconducting systems with strong spin orbit coupling. However, all of these systems are characterized by small energy gaps, and despite several decades of experimental work, definitive evidence for nonabelian anyons remains elusive. Here, we report the observation of arobust, incompressible even-denominator fractional quantum Hall phase in a new generation of dual-gated, hexagonal boron nitride encapsulated bilayer graphene samples. Numerical simulations suggest that this state is in the Pfaffian phase and hosts nonabelian anyons, and the measured energy gaps are several times larger than those observed in other systems. Moreover, the unique electronic structure of bilayer graphene endows the electron system with two new control parameters. Magnetic field continuously tunes the effective electron interactions, changing the even-denominator gap non-monotonically and consistent with predictions that a transition between the Pfaffian phase and the composite Fermi liquid (CFL) occurs just beyond the experimentally explored magnetic field range. Electric field, meanwhile, tunes crossings between levels from different valleys. By directly measuring the valley polarization, we observe a continuous transition from an incompressible to a compressible phase at half-filling mediated by an unexpected incompressible, yet polarizable, intermediate phase. Valley conservation implies this phase is an electrical insulator with gapless neutral excitations.

description: We examine the dynamics of nearest-neighbor bipartite concurrence and total correlations in the spin-1/2 $XXZ$ model with random fields. We show, starting from factorized random initial states, that the concurrence can suffer entanglement sudden death in the long time limit and therefore may not be a useful indicator of the properties of the system. In contrast, we show that the total correlations capture the dynamics more succinctly, and further reveal a fundamental difference in the dynamics governed by the ergodic versus many-body localized phases, with the latter exhibiting dynamical oscillations. Finally, we consider an initial state composed of several singlet pairs and show that by fixing the correlation properties, while the dynamics do not reveal noticeable differences between the phases, the long-time values of the correlation measures appear to indicate the critical region.

description: Plant morphology emerges from cellular growth and structure. The turgor-driven diffuse growth of a cell can be highly anisotropic: significant longitudinally and negligible radially. Such anisotropy is ensured by cellulose microfibrils (CMF) reinforcing the cell wall in the hoop direction. To maintain the cell's integrity during growth, new wall material including CMF must be continually deposited. We develop a mathematical model representing the cell as a cylindrical pressure vessel and the cell wall as a fibre-reinforced viscous sheet, explicitly including the mechano-sensitive angle of CMF deposition. The model incorporates interactions between turgor, external forces, CMF reorientation during wall extension, and matrix stiffening. Using the model, we reinterpret some recent experimental findings, and reexamine the popular hypothesis of CMF/microtubule alignment. We explore how the handedness of twisting cell growth depends on external torque and intrinsic wall properties, and find that cells twist left-handedly `by default' in some suitable sense. Overall, this study provides a unified mechanical framework for understanding left- and right-handed twist-growth as seen in many plants.

description: We study the von Neumann and Rényi entanglement entropy (EE) of scale-invariant theories defined on tori in 2+1 and 3+1 spacetime dimensions. We focus on spatial bi-partitions of the torus into two cylinders, and allow for twisted boundary conditions along the non-contractible cycles. Various analytical and numerical results are obtained for the universal EE of the relativistic boson and Dirac fermion conformal field theories (CFTs), and for the fermionic quadratic band touching and the boson with $z=2$ Lifshitz scaling. The shape dependence of the EE clearly distinguishes these theories, although intriguing similarities are found in certain limits. We also study the evolution of the EE when a mass is introduced to detune the system from its scale-invariant point, by employing a renormalized EE that goes beyond a naive subtraction of the area law. In certain cases we find non-monotonic behavior of the torus EE under RG flow, which distinguishes it from the EE of a disk.

description: Autophagy, which was originally identified in yeast, is a fundamental catabolic pathway that facilitates the isolation and transport of cytoplasmic material to the vacuole for degradation. Products of this degradation can then be returned to the cytosol for subsequent biosynthesis. Although autophagy is highly conserved throughout virtually all eukaryotes and the core mechanism of this pathway is well characterised, the physiological significance of autophagy remains poorly understood. As yeast often face conditions of nutrient limitation, it is generally assumed that autophagy acts as a recycling mechanism, supplying anabolic pathways during unfavourable environmental conditions, but limited evidence supports this notion. In this thesis, the physiological role of autophagy in Saccharomyces cerevisiae is discussed with a particular focus on the growth phenotypes of strains defective for autophagy. It is demonstrated that autophagy mutant strains on media supplemented with respiratory carbon sources experience a prolonged lag phase of growth. This phenotype is limited to strains lacking core components of the autophagy machinery and not selective forms of autophagy, such as mitophagy. Further interrogation of this phenotype revealed that autophagy most likely plays a role in the provision of one-carbon metabolites to the mitochondrion, supporting mitochondrial protein translation. These results suggest that rather than a role in bulk synthetic processes, such as general protein synthesis, autophagy may be important in the provision of essential precursor metabolites to selected metabolic pathways under specific conditions. Such intricacy is likely a reflection of the deep integra-tion of this fundamental eukaryotic phenomenon into the core metabolism of the cell.

description: The depletion and environmental problems associated with fossil fuels as main energy source motivates to look for alternative energy sources that do not compromise both food security and the environment. Sorghum is a fast-growing crop that can be harvested twice a year and produce both food (grain) and straw that can be utilized for ethanol production. The study explores the production of bioethanol from sequential acidic-alkaline pretreated sorghum straw hydrolysate. Sequential acid-alkaline pretreatment method was employed to obtain most intact monosaccharides from cellulose and hemicellulose. Dilute sulfuric acid (1%) pretreatment at 125 ℃ for 10 minutes was used at the first stage mainly for hemicellulose removal. In the second stage pretreatment, dilute sodium hydroxide (1.25 %) at 90 ℃ for 10 minutes was employed for delignification. The residues after the second pretreatment were hydrolyzed using dilute sulfuric acid of concentrations (2 %, 3%, and 4%), at temperatures (110 ℃, 125 ℃, and 140 ℃) and times (20, 40, and 30 minutes). The sugar concentration of the hydrolysates was determined using phenol sulfuric acid method. Three hydrolysates having sugar levels 30.42 g/L, 31.79 g/L, and 32.9875 g/L were selected for fermentation. Response surface methodology, Box-Behnken experimental design with design expert version 11.1.0.1 was applied to randomize and analyze the effects of the variables encountered in fermentation experiments. The experiments were done using the selected hydrolysates, varying size of inoculum (5 %, 10 %, and 15 %), and pH (4.5, 5, and 5.5) at 30 ℃ for 72 hours. The fermented samples were finally centrifuged and evaporated for purifying the ethanol. The yield of ethanol was determined after determining the percentage ethanol using digital density meter. FTIR analysis was done to determine the functional group of the product obtained and the result showed O-H, C-O, and C-H peaks similar to the standard ethanol. The results of the statistical analysis showed that all the three independent factors and the interaction between sugar level and pH affected the ethanol yield and a maximum of 0.617 mL/g yield was obtained at sugar level of 3.29875 g, pH of 5, and 15 % inoculum size. Generally, controlling fermentation parameters during the production of ethanol from sequential acidic-alkaline pretreated sorghum straw is a good choice in view of increasing yields of sugar and ethanol, decreasing dose and cost of chemicals, and minimizing waste generation.

description: The Quantum Approximate Optimization Algorithm (QAOA) is a hybrid quantum-classical algorithm to solve binary-variable optimization problems. Due to the short circuit depth and its expected robustness to systematic errors, it is one of the promising candidates likely to run on near-term quantum devices. We simulate the performance of QAOA applied to the Max-Cut problem and compare it with some of the best classical alternatives, for exact, approximate and heuristic solution. When comparing solvers, their performance is characterized by the computational time taken to achieve a given quality of solution. Since QAOA is based on sampling, we utilize performance metrics based on the probability of observing a sample above a certain quality. In addition, we show that the QAOA performance varies significantly with the graph type. By selecting a suitable optimizer for the variational parameters and reducing the number of function evaluations, QAOA performance improves by up to 2 orders of magnitude compared to previous estimates. Especially for 3-regular random graphs, this setting decreases the performance gap with classical alternatives. Because of the evolving QAOA computational complexity-theoretic guidance, we utilize a framework for the search for quantum advantage which incorporates a large number of problem instances and all three classical solver modalities: exact, approximate, and heuristic.

description: Recent experiments performed on cuprates and alkali-doped fullerides have demonstated that key signatures of superconductivity can be induced above the equilibrium critical temperature by optical modulation. These observations in disparate physical systems may indicate a general underlying mechanism. Multiple theories have been proposed, but these either consider specific features, such as competing instabilities, or focus on conventional BCS-type superconductivity. Here we show that periodic driving can enhance electron pairing in strongly-correlated systems. Focusing on the strongly-repulsive limit of the doped Hubbard model, we investigate in-gap, spatially inhomogeneous, on-site modulations. We demonstrate that such modulations substantially reduce electronic hopping, while simultaneously sustaining super-exchange interactions and pair hopping via driving-induced virtual charge excitations. We calculate real-time dynamics for the one-dimensional case, starting from zero and finite temperature initial states, and show that enhanced singlet--pair correlations emerge quickly and robustly in the out-of-equilibrium many-body state. Our results reveal a fundamental pairing mechanism that might underpin optically induced superconductivity in some strongly correlated quantum materials.
