EFFICIENCY AND REALISM IN STOCHASTIC BANDITS
Creators: name: CELLA, LEONARDO
Publisher: name: Universit� degli Studi di Milano
Year: 2021

description: This manuscript is dedicated to the analysis of the application of stochastic bandits to the recommender systems domain. Here a learning agent sequentially recommends one item from a catalog of available alternatives. Consequently, the environment returns a reward that is a noisy observation of the rating associated to the suggested item. The peculiarity of the bandit setting is that no information is given about not recommended products, and the collected rewards are the only information available to the learning agent. By relying on them the learner adapts his strategy towards reaching its learning objective, that is, maximizing the cumulative reward collected over all the interactions. In this dissertation we cover the investigation of two main research directions: the development of efficient learning algorithms and the introduction of a more realistic learning setting. In addressing the former objective we propose two approaches to speedup the learning process. The first solution aims to reduce the computational costs associated to the learning procedure, while the second's goal is to boost the learning phase by relying on data corresponding to terminated recommendation sessions. Regarding the latter research line, we propose a novel setting representing use-cases that do not fit in the standard bandit model.

description: Topology is a promising approach toward to the light ring in a generic black hole background, and equatorial timelike circular orbit in a stationary black hole background. In this paper, we consider the distinct topological configurations of the timelike circular orbits in static, spherically symmetric, and asymptotic flat black holes. By making use of the equation of motion of the massive particles, we construct a vector with its zero points exactly relating with the timelike circular orbits. Since each zero point of the vector can be endowed with a winding number, the topology of the timelike circular orbits is well established. Stable and unstable timelike circular orbits respectively have winding number +1 and -1. In particular, for given angular momentum, the topological number of the timelike circular orbits also vanishes whether they are rotating or not. Moreover, we apply the study to the Schwarzschild, scalarized Einstein-Maxwell, and dyonic black holes, which have three distinct topological configurations, representations of the radius and angular momentum relationship, with one or two pairs timelike circular orbits at most. It is shown that although the existence of scalar hair and quasi-topological term leads to richer topological configurations of the timelike circular orbits, they have no influence on the total topological number. These results indicate that the topological approach indeed provides us a novel way to understand the timelike circular orbits. Significantly, different topological configurations can share the same topology number, and hence belong to the same topological class. More information is expected to be disclosed when other different topological configurations are present.

description: The appearance of chaotic quantum dynamics significantly depends on the symmetry properties of the system, and in cold atomic systems many of these can be experimentally controlled. In this work, we systematically study the emergence of quantum chaos in a minimal system describing one-dimensional harmonically trapped Bose-Bose mixtures by tuning the particle-particle interactions. Using an advanced exact diagonalization scheme, we examine the transition from integrability to chaos when the inter-component interaction changes from weak to strong. Our study is based on the analysis of the level spacing distribution and the distribution of the matrix elements of observables in terms of the eigenstate thermalization hypothesis and their dynamics. We show that one can obtain strong signatures of chaos by increasing the inter-component interaction strength and breaking the symmetry of intra-component interactions.

description: We develop a general theory for one-way optical guiding in magnetized periodic particle arrays. Necessary conditions for a non-even dispersion curves are derived and presented in the context of Frieze symmetry-groups. It is shown, for example, that one-way guiding can be supported in particle \emph{strips} consisting of geometrically isotropic particles arranged in transversely asymmetric arrays. Specific examples consist e.g.~two parallel isotropic particle chains with different periods. The previously studied one-way effect based on the two-type rotation principle is shown to be a special case. In the latter the exclusion of the appropriate Frieze-symmetries is achieved in a single linear chain by associating a geometric rotation to each particle, thus providing the narrowest possible one-way waveguides. It is also shown that nearly any randomly created period may result in uneven dispersion and one-way guiding.

description: It is estimated that demand for food will continue to increase, as a result of population growth, but at the same time, food production will increasingly face huge constraints, such as water scarcity, soil desertification and the increase of fertilizers prices. Wastewater derived from food production chains should be treated in a sustainable way, to minimize environmental contamination, while maximizing the recovery of valuable fractions, such as plant nutrients. Bioelectrochemical systems (BES) have been proposed as solutions to treat different kinds of wastewaters and recover nutrients through bio-electrochemical reactions. In my project, new types of BES are studied, fabricated with biocompatible and biogenic materials starting from vegetable scraps, which could be applied as mean of organic matter and nutrients recovery from organic-rich wastewater streams coming from important agro-food chains, such as farming and agro-industrial productions. This novel type of BES was named ?microbial recycling cells? (MRCs). Biochar produced from controlled pyrolysis of plant materials is electro-conductive and can be used as base to fabricate MRCs, which can be used for this scope. Other materials like earthenware were also used in MRCs architectures, as electrolytic conductors and structural frames. After being enriched of nutrients from wastewaters, biochar-based MRCs can be fully recycled to produce soil improvers and renewable fertilizers. In soil applications, the electrochemical properties of biochar influence soil biogeochemical reactions, with important implications in plant nutrition and the environmental implications of soil-plant systems (e.g. carbon sequestration, CH4 emissions, etc.). The PhD project was hold in 3 different work packages: WP1) Selection of MRC architectures and optimization of e-biochar properties, WP2) Study of the microbial electrochemical processes driving nutrients deposition, WP3) Study of the properties of nutrients-enriched biochar derived from MRC after their life-cycle, as soil improvers of agricultural soil fertility, with both amending and fertilizing properties.

description: Recent development of high-resolution mass spectrometry (MS) instruments enables chemical cross-linking (XL) to become a high-throughput method for obtaining structural information about proteins. Restraints derived from XL-MS experiments have been used successfully for structure refinement and protein-protein docking. However, one formidable question is under which circumstances XL-MS data might be sufficient to determine a protein's tertiary structure de novo? Answering this question will not only include understanding the impact of XL-MS data on sampling and scoring within a de novo protein structure prediction algorithm, it must also determine an optimal cross-linker type and length for protein structure determination. While a longer cross-linker will yield more restraints, the value of each restraint for protein structure prediction decreases as the restraint is consistent with a larger conformational space. In this study, the number of cross-links and their discriminative power was systematically analyzed in silico on a set of 2,055 non-redundant protein folds considering Lys-Lys, Lys-Asp, Lys-Glu, Cys-Cys, and Arg-Arg reactive cross-linkers between 1 Å and 60 Å. Depending on the protein size a heuristic was developed that determines the optimal cross-linker length. Next, simulated restraints of variable length were used to de novo predict the tertiary structure of fifteen proteins using the BCL::Fold algorithm. The results demonstrate that a distinct cross-linker length exists for which information content for de novo protein structure prediction is maximized. The sampling accuracy improves on average by 1.0 Å and up to 2.2 Å in the most prominent example. XL-MS restraints enable consistently an improved selection of native-like models with an average enrichment of 2.1.

description: Autonomous vehicles (AVs) must share the driving space with other drivers and often employ conservative motion planning strategies to ensure safety. These conservative strategies can negatively impact AV's performance and significantly slow traffic throughput. Therefore, to avoid conservatism, we design an interaction-aware motion planner for the ego vehicle (AV) that interacts with surrounding vehicles to perform complex maneuvers in a locally optimal manner. Our planner uses a neural network-based interactive trajectory predictor and analytically integrates it with model predictive control (MPC). We solve the MPC optimization using the alternating direction method of multipliers (ADMM) and prove the algorithm's convergence. We provide an empirical study and compare our method with a baseline heuristic method.
A synchronized two-dimensional $α-Ω$ model of the solar dynamo

description: We consider a conventional $α-Ω$-dynamo model with meridional circulation that exhibits typical features of the solar dynamo, including a Hale cycle period of around 20 years and a reasonable shape of the butterfly diagram. With regard to recent ideas of a tidal synchronization of the solar cycle, we complement this model by an additional time-periodic $α$-term that is localized in the tachocline region. It is shown that amplitudes of some dm/s are sufficient for this $α$-term to become capable of entraining the underlying dynamo. We argue that such amplitudes of $α$ may indeed be realistic, since velocities in the range of m/s are reachable, e.g., for tidally excited magneto-Rossby waves.

description: Epidemiologists have grouped the multiple disorders that lead to preterm delivery before the 28th week of gestation in a variety of ways. The authors sought to identify characteristics that would help guide how to classify disorders that lead to such preterm delivery. They enrolled 1,006 women who delivered a liveborn singleton infant of less than 28 weeks' gestation at 14 centers in the United States between 2002 and 2004. Each delivery was classified by presentation: preterm labor (40%), prelabor premature rupture of membranes (23%), preeclampsia (18%), placental abruption (11%), cervical incompetence (5%), and fetal indication/intrauterine growth restriction (3%). Using factor analysis (eigenvalue = 1.73) to compare characteristics identified by standardized interview, chart review, placental histology, and placental microbiology among the presentation groups, the authors found 2 broad patterns. One pattern, characterized by histologic chorioamnionitis and placental microbe recovery, was associated with preterm labor, prelabor premature rupture of membranes, placental abruption, and cervical insufficiency. The other, characterized by a paucity of organisms and inflammation but the presence of histologic features of dysfunctional placentation, was associated with preeclampsia and fetal indication/intrauterine growth restriction. Disorders leading to preterm delivery may be separated into two groups: those associated with intrauterine inflammation and those associated with aberrations of placentation.

description: We study time evolutions of charged scalar perturbations on the background of a charged hairy black hole, in which the perturbations can be governed by a double-peak effective potential. By extracting quasinormal modes from the waveform of scalar perturbations, we discover that some quasinormal modes, which are trapped in a potential well between two potential peaks, can be superradiantly amplified. These superradiant modes make the hairy black hole unstable against charged scalar perturbations. Moreover, it is found that the superradiant modes arise from the competition between the superradiant amplification caused by tunneling through the outer potential barrier and the leakage of modes through the inner potential barrier into the black hole.

description: Despite the belief that the etiology of and risk factors for rectal cancer might differ from those for colon cancer, relatively few studies have examined rectal cancer in relation to use of nonsteroidal antiinflammatory drugs (NSAIDs). The authors evaluated the association between NSAIDs and distal large bowel cancer in African Americans and whites, using data from a population-based case-control study of 1,057 incident cases of adenocarcinoma of the sigmoid colon, rectosigmoid junction, and rectum and 1,019 controls from North Carolina (2001–2006). NSAID use was inversely associated with distal large bowel cancer in whites (odds ratio (OR) = 0.60, 95% confidence interval (CI): 0.46, 0.79). The inverse association was evident for all types of NSAIDs but was slightly stronger with prescription NSAIDs, particularly selective cyclooxygenase 2 inhibitors (OR = 0.38, 95% CI: 0.25, 0.56). Compared with whites, a relatively weak inverse association was found in African Americans (OR = 0.87, 95% CI: 0.55, 1.40), although odds ratio heterogeneity by race could not be confirmed (P = 0.21). In addition, the strength of the association with NSAIDs varied by tumor location, suggesting more potent effects for rectal and rectosigmoid cancers than for sigmoid cancer. The chemopreventive potential of NSAIDs might differ by population and by tumor characteristics.

description: High-level arsenic exposure is consistently associated with QT prolongation, a risk factor for arrhythmia and sudden cardiac death. Arsenic may act on QT by increasing cardiac calcium currents. The authors hypothesized that low-level arsenic exposure would be associated with QT duration and that this effect would be stronger among persons not using calcium channel blockers. They performed a cross-sectional analysis in elderly men from the Normative Aging Study to analyze associations between toenail arsenic and QT and heart rate-corrected QT (QTc) durations and to examine effect modification by calcium channel blocker use, using linear regression and adjusting for potential confounders. Participants were examined in Boston, Massachusetts, between 2000 and 2002 or in 2006. An interquartile range increase in arsenic concentration was associated with a 3.8-millisecond increase in QT (95% confidence interval: 0.82, 6.8) and a 2.5-millisecond increase in QTc (95% confidence interval: 0.11, 4.9). There was no evidence of effect modification by medication use for either QT (P = 0.93) or QTc (P = 0.58). The authors observed positive associations between a biomarker of arsenic exposure and QT duration but found no evidence of effect modification by calcium channel blocker use, possibly because of modest power.

description: We derive exact and closed-form expressions for a large class of two-point and three-point inflation correlators with the tree-level exchange of a single massive particle. The intermediate massive particle is allowed to have arbitrary mass, spin, chemical potential, and arbitrary nonderivative or derivative couplings to external inflaton modes. We also allow the coupling coefficients to have arbitrary complex power dependences on the conformal time. Our results feature closed-form expressions involving only familiar special functions and without any infinite sums. This is achieved by an improved bootstrap method with a suitable change of variables. Our results cover a wide range of cosmological collider models and can be directly used for future phenomenological studies. Our results can also be used as basic building blocks for constructing more complicated inflation correlators.

The search is performed with the ALICE detector in central (0-10%) Pb-Pb collisions at $ \sqrt{s_{\rm{NN}}} = 2.76$ TeV, by invariant mass analysis in the decay modes $\bar{Λ\mathrm{n}} \rightarrow \bar{\mathrm{d}} π^{+} $ and H-dibaryon $\rightarrow Λ\mathrm{p} π^{-}$. No evidence for these bound states is observed. Upper limits are determined at 99% confidence level for a wide range of lifetimes and for the full range of branching ratios. The results are compared to thermal, coalescence and hybrid UrQMD model expectations, which describe correctly the production of other loosely bound states, like the deuteron and the hypertriton.

HIGGS BOSON PRODUCTION AT THE LARGE HADRON COLLIDER:ACCURATE THEORETICAL PREDICTIONS AT HIGHER ORDERS IN QCD

Publisher: name: Universit� degli Studi di Milano

description: We present a new numerical program, HTurbo, which provides fast and numerically precise predictions for Higgs boson production cross sections. The present version of the code implements the perturbative QCD expansion up to the next-to-next-to-leading order also combined with the resummation of the large logarithmic corrections at small transverse momenta up to next-to-next-to-leading logarithmic accuracy and it includes the Higgs boson production, through gluon fusion, and decay in two photons with the full dependence on the final-state kinematics. Arbitrary kinematical cuts can be applied to the final states in order to obtain fiducial cross sections and associated kinematical distributions. We present a benchmark comparison with the predictions obtained with the numerical programs HRes and HNNLO programs for which HTurbo represents an improved reimplementation. The architecture of HTurbo is built such that it allows for a straightforward implementation of the next-to-next-to-next-to-leading logarithmic accuracy (N3LL), and it sets the first implementation of the resummation at N3LL for Higgs boson production.

description: The quantum ratchet current is studied in the parameter space of the dissipative kicked rotor model coupled to a zero temperature quantum environment. We show that vacuum fluctuations blur the generic isoperiodic stable structures found in the classical case. Such structures tend to survive when a measure of statistical dependence between the quantum and classical currents are displayed in the parameter space. In addition, we show that quantum fluctuations can be used to overcome transport barriers in the phase space. Related quantum ratchet current activation regions are spotted in the parameter space. Results are discussed {based on quantum, semiclassical and classical calculations. While the semiclassical dynamics involves vacuum fluctuations, the classical map is driven by thermal noise.

description: When waist circumference is taken into account, larger hip circumference is associated with reduced risk factors for diabetes and cardiovascular disease. The authors investigated the prospective association of hip circumference with type 2 diabetes and coronary heart disease (CHD) incidence in a biracial cohort of men and women in 4 US communities. A total of 10,767 participants from the Atherosclerosis Risk in Communities (ARIC) study were followed from 1987 to 1998. Hip and waist circumferences and body mass index (BMI) were modeled separately and mutually in association with incident diabetes and CHD by using proportional hazards regression. After adjustment for age, race, sex, and clinical center, hip circumference was positively associated with incident diabetes. However, after further controlling for waist circumference, BMI, and confounding variables, successive quintiles of hip circumference were associated with a statistically significant reduced hazard of incident diabetes (hazard ratios = 1.00, 0.79, 0.60, 0.44, 0.41). Similarly, successive quintiles of hip circumference were associated with a statistically significant reduced hazard of CHD after controlling for waist circumference, BMI, and confounding variables (hazard ratios = 1.00, 0.92, 0.75, 0.63, 0.50). Although excess adiposity is a general risk factor for diabetes and CHD, for a given BMI and waist circumference, greater hip circumference appears to lessen the risk of diabetes and CHD.

description: Very large DC and AC electric fields cannot be sustained between conducting electrodes because of volume gas breakdown and/or surface field emission. However, very large potential fields are now routinely generated in plasma structures such as laser generated wake in unmagnetized plasmas. In magnetized plasmas, large DC fields can also be sustained and controlled perpendicular to the magnetic field, but the metallic end plates limiting the plasma, terminating the magnetic field lines and usually providing the voltage drop feed between the field lines, impose severe restrictions on the maximum field. However, it is shown that very large radial DC voltage drops can be sustained by injecting waves of predetermined frequencies and wave vectors, traveling along the azimuthal direction of an axially magnetized plasma cylinder, or by injecting fast neutral particles beams along this azimuthal direction. The large conductivity along the magnetic field lines and the small conductivity between the field lines then distribute this voltage drop. The global power balance and control parameters of wave and beam generated large DC electric fields in magnetized plasmas are identified, described and analyzed.

description: Age-dependent changes in murine cardiac pacemaker activity. Cardiovascular diseases (CDVs) are the main causes of death. The incidence of morbidity and mortality associated with CDVs increases exponentially in the elderly population due to the increase of both the number of old people and of the average lifespan (for example it is estimated that in the United States there will be 70 million people over the age of 65 by the year 2030, representing almost 25% of the population, 6 . Amongst the age-dependent cardiovascular diseases, the sinoatrial node dysfunction has a primary role 7 ; for this reason, there is a high interest in the study of the pathophysiological mechanisms that are at the basis of cardiac aging. It is known that in humans during ageing there is a decline in maximum heart rate (MHR) and a reduction in the intrinsic heart rate (IHR) 8,9 ; however basal heart rate (BHR) remains the same between the adults and the elderly 10 . We thus decided to better understand the age-associated mechanisms responsible for the changes in intrinsic and maximum heart rate but not in the basal heart rate, and we chose the mouse as a study model. We therefore first confirmed that in our murine model the IHR, but not the basal HR, decreases with ageing; and we also noticed that in adult mice the IHR and the BHR were similar. We focused our studies on the funny current since it is a main contributor to pacemaking generation and modulation and we observed a reduction of the current density and a negative shift of the activation curve in the old animals. We then evaluated the influence of the autonomic system and we found that in adult mice both branches of the autonomic system contribute similarly to HR, though in opposite directions; old mice instead had a lower vagal tone, leading to a reduction in the overall HRV as assessed by spectral analysis, and an increased sympathetic tone, leading to a larger vulnerability to spontaneous arrhythmias compared to adult. Our data highlight that this model recapitulates well the HR features observed in aged humans and can help understanding the mechanisms of the ageing-associated changes in heart chronotropism. The shift of the sympatho-vagal balance toward a sympathetic prevalence in the old animals may explain why, despite the difference in the intrinsic heart rate, the basal heart rate is similar between the two groups. While the current view is that the sympathetic increase is necessary to ensure the homeostatic balance of heart rate during ageing, it is also possible that the age-dependent increase of the sympathetic tone is the cause of the reduction of the intrinsic heart rate which therefore ultimately represents the compensatory effect.

description: Challenges in the accurate measurement of sexual behavior in human immunodeficiency virus (HIV) prevention research are well documented and have prompted discussion about whether valid assessments are possible. Audio computer-assisted self-interviewing (ACASI) may increase the validity of self-reported behavioral data. In 2006–2007, Zimbabwean women participated in a randomized, cross-sectional study that compared self-reports of recent vaginal sex and condom use collected through ACASI or face-to-face interviewing (FTFI) with a validated objective biomarker of recent semen exposure (prostate-specific antigen (PSA) levels). Of 910 study participants, 196 (21.5%) tested positive for PSA, an indication of semen exposure during the previous 2 days. Of these 196 participants, 23 (11.7%) reported no sex in the previous 2 days, with no difference in reported sexual activity between interview modes (12.5% ACASI vs. 10.9% FTFI; Fisher's exact test: P = 0.72). In addition, 71 PSA-positive participants (36.2%) reported condom-protected vaginal sex only; their reports also indicated no difference between interview modes (33.7% ACASI vs. 39.1% FTFI; P = 0.26). Only 52% of PSA-positive participants reported unprotected sex during the previous 2 days. Self-report was a poor predictor of recent sexual activity and condom use in this study, regardless of interview mode, providing evidence that such data should be interpreted cautiously.
Estimation of the Relative Excess Risk Due to Interaction and Associated Confidence Bounds

description: The relative excess risk due to interaction (RERI) provides a useful metric of departure from additivity of effects on a relative risk scale. In this paper, the authors show that RERI is identical to the product term in a linear odds ratio or a linear relative risk model. SAS and STATA codes are provided for fitting a linear odds ratio model that directly parameterizes RERI. In addition, this paper presents a method for obtaining likelihood-based 95% confidence bound estimates for RERI. The authors show that likelihood-based confidence intervals may differ substantially from the asymptotic confidence interval estimates advocated by previous authors. The approach presented in this paper should facilitate estimation of RERI and associated likelihood-based confidence bounds, by using standard statistical packages.
title: Evaluation of Human and Ecological Water Management Tradeoffs in a Seasonal Watershed with Spatially-Distributed Demands
Creators: name: Rowles, Jesse Lee
Publisher: name: Utah State University

description: River managers must balance the needs of the ecosystems that rely on the river by leaving water instream, often while also considering human demands. It is especially difficult to balance these water needs in systems that are highly seasonal and have no instream storage (e.g., reservoirs) since water cannot be stored for use throughout the year. An example of a watershed that has both of these characteristics is the South Fork Eel River in coastal northern California. In order to evaluate tradeoffs between human and ecological demands in this system, a water allocation model with water management scenarios and environmental flow requirement scenarios was developed in collaboration with stakeholders and decision-makers to balance the needs of the ecosystem and humans. The water allocation model is capable of considering permitted water diversions, as well as unpermitted diversions, particularly pertaining to cannabis cultivation, which contribute to a significant proportion of water used in forested California watersheds. In total, 11 different human water demand scenarios and 14 different environmental flow requirement ecological demand scenarios were evaluated to identify sensitivity of different parameters and facilitate management efforts. To aid in decision making processes, an interactive GUI is also being collaboratively developed to provide visualizations and performance metrics of model results. Then, the results of the water allocation model were assessed compared to different location-specific characteristics.
HALOGEN BONDING: A DFT AND VB INVESTIGATION

description: During my Ph.D. I focused my attention on the study of properties of the halogen bonding from a computational point of view. Due to the growing attention towards this kind of interaction, it is important to have some computational and theoretical models able to explain and reproduce its features. Halogen bonding, indeed, has been demonstrated to be a powerful tool due to the large number of applications in different fields, ranging from biological macromolecules to supramolecular chemistry (such as assemblies with nonlinear optical properties), from nanomaterials and crystal engineering (like the self-assembly control of host-guest solids, with applications in liquid-crystalline, porous, magnetic and organic phosphorescent materials) to materials science (such as the development of solid-state materials with peculiar electronic properties). Though a plethora of theoretical studies have been carried out on this interaction, there are still some open questions to be solved. I have investigated halogen bonding by using mainly two computational approaches, that is the Density Functional Theory (DFT) and the Valence Bond Spin-Coupled Theory. The first one is implemented in a number of widely used computational chemistry software programs, while the second one has been implemented by a restricted number of research groups, according to different strategies. In this thesis, after an introduction on the main properties of halogen bonding, I will briefly describe the Spin-Coupled Theory formulated on the Slater determinants, adopted for the present studies. The related software, developed by my supervisor Prof. M. Sironi, was able to treat up to 11 valence electrons. During my Ph.D. thesis, I worked in order to overcome this limitation: the software now runs on systems with up to 14 valence electrons. Finally, I will show the issues tackled and discuss the results obtained.
