description: Através de raids de intervenção em territórios vizinhos, de missões de firme pacificação de áreas limítrofes ou sob administração egípcia, por determinação do poder central ou de altos funcionários regionais, ou de vitoriosas campanhas militares planeadas pelo Estado, desde o Império Antigo que chegaram ao Egipto contingentes humanos que se integram na categoria de prisioneiros de guerra (sekeru-ankh, “prisioneiros/ cativos vivos”). Qual a proveniência dos prisioneiros de guerra no Império Antigo e no Império Médio? Que tipos de prisioneiros existiram nestes dois períodos mais recuados da história egípcia? Que funções lhes estavam destinadas? Pelas fontes disponíveis, de carácter narrativo-literário e/ ou plástico-iconográfico, podemos perceber esta realidade social e o seu enquadramento no universo demográfico e mental egípcio, responder a estas questões e traçar uma panorâmica diversificada dos prisioneiros de guerra, sempre enquadrada por um conceito egípcio de História em que a realeza, a ideologia e a legitimação influíam directamente na arte da guerra.

description: O mito de Orfeu e Eurídice foi perpetuado durante séculos pela literatura, pintura, música e cinema. É impossível analisar todos os processos da transmissão (oral / versões escritas e transmediação) deste mito. Todavia, ao revisitar o tema órfico, relembro o particular interesse que a Professora Laura mostrou por meu artigo previamente publicado na revista Gaudium Sciendi. Por isso, o ponto de partida deste contributo é a retrospetiva, destacando obras relacionadas de modernistas como Goll e Kokoschka, mas também de autores como Keats e Celan.

A autobiografia americana como testemunho e caução de cidadania
Creators: name: Alves, Teresa F. A.
Publisher: name: Gaudium Sciendi
Year: 2022

description: A atracção da autobiografia à esfera da cidadania americana constitui o foco deste ensaio escrito em homenagem a Maria Laura Bettencourt Pires que, em boa parte da sua ensaística e prática docente, se empenhou a fundo na cultura americana. A interligação entre a escrita do “eu” e a questão da cidadania é desenvolvida por recurso a uma série de textos assinados por autores e autoras das várias culturas dos EUA, nomeadamente a cultura dominante e outras que, a par dela e no seu seio, alcançaram expressão. Abrange um arco temporal em que tal vertente literária floresce, moldada por desígnios que aparentam emular os da Declaração da Independência (1776), onde se firmam os direitos inalienáveis de cada indivíduo confrontado com uma nova identidade política. Ao correr do texto, são analisadas as autobiografias de Benjamin Franklin, Henry David Thoreau, Margaret Fuller, William Apess, Frederick Douglass, Harriet A. Jacobs, Gertrude Bonin/ Zitkala-Sa e Mary Antin. É dado relevo ao modo singular e único de entrelaçamento de cada uma das vidas analisadas com as circunstâncias sociais e políticas do seu tempo. Complementarmente, considera-se o impacto que tiveram nessas mesmas circunstâncias e a forma como contribuíram para a configuração do conceito de representatividade americana e a sucessiva redefinição desse conceito.

description: $J/ψ$ production at forward and midrapidity at the Relativistic Heavy-Ion Collider (RHIC) is calculated within a previously constructed rate-equation approach accounting for both direct production and regeneration from $c$ and $\bar c$. The results are compared to experimental data. The observed stronger suppression at forward rapidity can be qualitatively explained by a smaller statistical regeneration component together with stronger cold nuclear matter induced suppression compared to midrapidity. The $χ_c$ over $J/ψ$ ratio and $ψ'$ over $J/ψ$ ratio are also calculated.

description: Understanding the interactions between the atmosphere, the land, and the subsurface is fundamental to hydrology and is critical for a better assessment of the impacts of climate change and human management on hydrological systems. However, many land surface models simplify the subsurface hydrology and thereby these interactions. In this study, we couple the land surface model Noah-MP included in the NASA Land Information System (LIS) with the integrated hydrologic model ParFlow (ParFlow-LIS) using the Earth System Modeling Framework (ESMF) and the National United Operational Prediction Capability (NUOPC). This coupling improves the simulation of water and energy cycle processes by adding the three-dimensional variably saturated and heterogeneous flow in the subsurface using sophisticated and nonlinear physics-based equations as well as the advances in satellite remote sensing-based data assimilation of the land surface, thereby benefiting the integrated hydrologic modeling and data assimilation community. We use the High Plains aquifer, located in the central United States, as a testbed to evaluate the coupled ParFlow-LIS system. The new ParFlow-LIS system accounts for the effects of topographically driven flows on the land surface, producing more fine-scale patterns of land surface states and fluxes than standalone LIS. In addition, ParFlow-LIS enables the consideration of the effect of subsurface water storage on evapotranspiration. This is particularly important in areas and times with dry soils, such as during drought conditions or in the presence of a cone of depression due to pumping.

On the possibility of light string resonances at the LHC and Tevatron from Randall-Sundrum throats

description: In string realizations of the Randall-Sundrum scenario, the higher-spin Regge excitations of Standard Model states localized near the IR brane are warped down to close to the TeV scale. We argue that, as a consequence of the localization properties of Randall-Sundrum models of flavour, the lightest such resonance is the spin-3/2 excitation of the right-handed top quark over a significant region of parameter space. A mild accidental cancellation allows this resonance to be as light or lighter than the Kaluza-Klein excitations of the Standard Model states. We consider from a bottom-up effective theory point of view the production and possible observability of such a spin-3/2 excitation at the LHC and Tevatron. Current limits are weaker than might be expected because of the excess of WWjj events at the Tevatron reported by CDF for an invariant mass of 400-500 GeV.

description: Structure functions of polarized spin-1 hadrons will be measured at various accelerator facilities in the near future. Recently, transverse-momentum-dependent and collinear parton distribution functions were theoretically proposed at twist 3 and twist 4 in addition to the twist-2 ones, so that full investigations became possible for structure functions of spin-1 hadrons in the same level with those of the spin-1/2 nucleons. Furthermore, twist-3 tensor-polarized multiparton distribution functions were also recently found for spin-1 hadrons. In this work, we show relations among the collinear parton- and multiparton-distribution functions for spin-1 hadrons by using equation of motion for quarks. These relations are valuable in constraining the distribution functions and learning about multiparton correlations in spin-1 hadrons.

description: The X-ray emission from blazars has been widely investigated using several space telescopes. In this work, we explored statistical properties of the X-ray variability in the blazars S5 0716+714, OJ 287, Mkn 501 and RBS 2070 using the archival observations from the XMM-Newton telescope between the period 2002-2020. Several methods of timing and spectral analyses including fractional variability, minimum variability timescale, power spectral density analyses and countrate distribution were performed. In addition, we fitted various spectral models to the observations as well as estimated hardness ratio. The results show that the sources are moderately variable within the intra-day timescale. Three of the four sources exhibited a clear bi-modal pattern in their countrate distribution revealing possible indication of two distinct countrate states, that is, hard and soft countrate states. The slope indices of the power spectral density were found to be centered around 0.5. Furthermore, the spectra of the sources were fitted with single power-law, broken power-law, log-parabolic and black-body+log-parabolic models (the latter only for OJ 287). We conclude that for most of the observations log-parabolic model was the best fit. The power spectral density analysis revealed the variable nature of PSD slopes in the source light curves. The results of this analysis could indicate the non-stationary nature of the blazar processes on intra-day timescales. The observed features can be explained within the context of current blazar models, in which the non-thermal emission mostly arises from kilo-parsec scale relativistic jets.

description: PRholog is an experimental extension of logic programming with strategic conditional transformation rules, combining Prolog with Rholog calculus. The rules perform nondeterministic transformations on hedges. Queries may have several results that can be explored on backtracking. Strategies provide a control on rule applications in a declarative way. With strategy combinators, the user can construct more complex strategies from simpler ones. Matching with four different kinds of variables provides a flexible mechanism of selecting (sub)terms during execution. We give an overview on programming with strategies in PRholog and demonstrate how rewriting strategies can be expressed.
NGC 2004 #115: a black hole imposter containing three luminous stars

description: NGC 2004 #115 is a recently identified black hole (BH) candidate in the Large Magellanic Cloud (LMC) containing a B star orbiting an unseen companion in a 2.9 day orbit and Be star tertiary. We show that the unseen companion is not a $25\,M_{\odot}$ BH, but a $(2-3)\,M_{\odot}$ luminous star. Analyzing the OGLE and MACHO light curves of the system, we detect ellipsoidal variability with amplitude 10 times larger than would be expected if the companion were a $25\,M_{\odot}$ BH, ruling out the low inclination required for a massive companion. The light curve also shows a clear reflection effect that is well-modeled with a $2.5\,M_{\odot}$ main-sequence secondary, ruling out a lower-mass BH or neutron star companion. We consider and reject models in which the system is a binary containing a stripped star orbiting the Be star: only a triple model with an outer Be star can explain both the observed light curve and radial velocities. Our results imply that the B star, whose slow projected rotation velocity and presumed tidal synchronization were interpreted as evidence for a low inclination (and thus a high companion mass), is far from being tidally synchronized: despite being in a 2.9 day orbit that is fully or nearly circularized ($e < 0.04$), its surface rotation period appears to be at least 20 days. We offer cautionary notes on the interpretation of dormant BH candidates in binaries.

The Women’s Resources Centre - 1974
Creators: name: James, Alice
Publisher: name: University of British Columbia

description: The Women's Resources Centre of the Centre for Continuing Education at the University of British Columbia provides programs and services to assist women in life planning. This study Investigated these programs and services in order to gain insight into the process of adopting a life style more broadly based in the community. A fifty per cent random sample of the women who came to this centre for short courses from February to April 1974 and a fifty per cent random sample of women who came for individual counselling in January 1974 were selected for this study. The investigation used the open-ended probing interview to gain greater understanding of the total life situation of these women. The study found considerable evidence that women under forty felt pressure to adopt two different life styles under conditions where these life styles were mutually exclusive. This was reflected in the prevalence of reporting of anxiety, frustration, muscular tension and illnesses such as myasthenia gravis. The highest incidence of illness was amongst women who had no children. There was a heavy incidence of both childbearing and marriage breakup between the ages of thirty and thirty-four. Housewives over the age of forty also felt pressure to change to a career oriented life style but were without the knowledge, means or opportunity to do this successfully. For these women life planning became a process of identifying a series of conflicting pressures and making a decision as to whether to break a paired role relationship or to use persuasion to reduce this conflict. Decisions were made on the basis of their evaluation of the interaction of several factors: the necessity to maintain a role which provided the necessities of life, e.g. housewife, employed worker, self-employed worker or welfare recipient; the degree of urgency involved in dealing with the erosion of physical and mental health; the recognition of the time factor in the changing of attitudes; their skill in effecting attitude change; and their ability to move into more varied forms of physical activity to slow down the erosion of physical and mental health. The study concluded that communication beyond the immediate family is an important factor in making good decisions and that making changes in life style is a stressful and time consuming process. This study also made recommendations to adult educators directed towards making the process of adoption of a different life style less stressful.
Parity-mixed coupled-cluster formalism for computing parity-violating amplitudes

description: We formulate a parity-mixed coupled-cluster (PM-CC) approach for high-precision calculations of parity non-conserving amplitudes in mono-valent atoms. Compared to the conventional formalism which uses parity-proper (PP) one-electron orbitals, the PM-CC method is built using parity-mixed (PM) orbitals. The PM orbitals are obtained by solving the Dirac-Hartree-Fock equation with the electron-nucleus electroweak interaction included (PM-DHF). There are several advantages to such a PM-CC formulation: (i) reduced role of correlations, as for the most experimentally-accurate to date ${}^{133}{\rm Cs}\,$ $6S_{1/2}-7S_{1/2}$ transition, the PM-DHF result is only 3% away from the accurate many-body value, while the conventional DHF result is off by 18%; (ii) avoidance of directly summing over intermediate states in expressions for parity non-conserving amplitudes which reduces theoretical uncertainties associated with highly-excited and core-excited intermediate states, and (iii) relatively straightforward upgrade of existing and well-tested large-scale PP-CC codes. We reformulate the CC method in terms of the PM-DHF basis and demonstrate that the cluster amplitudes are complex numbers with opposite parity real and imaginary parts. We then use this fact to map out a strategy through which the new PM-CC scheme may be implemented.

description: The three-judges protocol, recently advocated by Mclver and Morgan as an example of stepwise refinement of security protocols, studies how to securely compute the majority function to reach a final verdict without revealing each individual judge's decision. We extend their protocol in two different ways for an arbitrary number of 2n+1 judges. The first generalisation is inherently centralised, in the sense that it requires a judge as a leader who collects information from others, computes the majority function, and announces the final result. A different approach can be obtained by slightly modifying the well-known dining cryptographers protocol, however it reveals the number of votes rather than the final verdict. We define a notion of conditional anonymity in order to analyse these two solutions. Both of them have been checked in the model checker MCMAS.

description: Two new high-entropy ceramics (HECs) in the weberite and fergusonite structures, along with unexpected formation of ordered pyrochlore phases with ultrahigh-entropy compositions and an abrupt pyrochlore-weberite transition, are discovered in a 21-component oxide system. While the Gibbs phase rule allows 21 equilibrium phases, nine out of the 13 compositions examined possess single HEC phases (with ultrahigh ideal configurational entropies: ~2.7kB per cation or higher on one sublattice in most cases). Notably, (15RE1/15)(Nb1/2Ta1/2)O4 possess a single monoclinic fergusonite (C2/c) phase and (15RE1/15)3(Nb1/2Ta1/2)1O7 form a single orthorhombic (C2221) weberite phase, where 15RE1/15 represents Sc1/15Y1/15La1/15Pr1/15Nd1/15Sm1/15Eu1/15Gd1/15Tb1/15Dy1/15Ho1/15Er1/15Tm1/15Yb1/15Lu1/15. Moreover, a series of eight (15RE1/15)2+x(Ti1/4Zr1/4Ce1/4Hf1/4)2-2x(Nb1/2Ta1/2)xO7 specimens all exhibit single phases, where a pyrochlore-weberite transition occurs within 0.75 < x < 0.8125. This cubic-to-orthorhombic transition does not change the temperature-dependent thermal conductivity appreciably, as the amorphous limit may have already been achieved in the ultrahigh-entropy 21-component oxides. These discoveries expand the diversity and complexity of HECs, towards many-component compositionally complex ceramics (CCCs) and ultrahigh-entropy ceramics.

description: The objectives of this work are cross-modal text-audio and audio-text retrieval, in which the goal is to retrieve the audio content from a pool of candidates that best matches a given written description and vice versa. Text-audio retrieval enables users to search large databases through an intuitive interface: they simply issue free-form natural language descriptions of the sound they would like to hear. To study the tasks of text-audio and audio-text retrieval, which have received limited attention in the existing literature, we introduce three challenging new benchmarks. We first construct text-audio and audio-text retrieval benchmarks from the AudioCaps and Clotho audio captioning datasets. Additionally, we introduce the SoundDescs benchmark, which consists of paired audio and natural language descriptions for a diverse collection of sounds that are complementary to those found in AudioCaps and Clotho. We employ these three benchmarks to establish baselines for cross-modal text-audio and audio-text retrieval, where we demonstrate the benefits of pre-training on diverse audio tasks. We hope that our benchmarks will inspire further research into audio retrieval with free-form text queries. Code, audio features for all datasets used, and the SoundDescs dataset are publicly available at https://github.com/akoepke/audio-retrieval-benchmark.

description: For each pair $(Q_i,Q_j)$ of reference points and each real number $r$ there is a unique hyperplane $h \perp Q_iQ_j$ such that $d(P,Q_i)^2 - d(P,Q_j)^2 = r$ for points $P$ in $h$. Take $n$ reference points in $d$-space and for each pair $(Q_i,Q_j)$ a finite set of real numbers. The corresponding perpendiculars form an arrangement of hyperplanes. We explore the structure of the semilattice of intersections of the hyperplanes for generic reference points. The main theorem is that there is a real, additive gain graph (this is a graph with an additive real number associated invertibly to each edge) whose set of balanced flats has the same structure as the intersection semilattice. We examine the requirements for genericity, which are related to behavior at infinity but remain mysterious; also, variations in the construction rules for perpendiculars. We investigate several particular arrangements with a view to finding the exact numbers of faces of each dimension. The prototype, the arrangement of all perpendicular bisectors, was studied by Good and Tideman, motivated by a geometric voting theory. Most of our particular examples are suggested by extensions of that theory in which voters exercise finer discrimination. Throughout, we propose many research problems.

description: We study the cosmological sector of the Lorentzian Barrett-Crane (BC) model coupled to a free massless scalar field in its Group Field Theory (GFT) formulation, corresponding to the mean-field hydrodynamics obtained from coherent condensate states. The relational evolution of the condensate with respect to the scalar field yields effective dynamics of homogeneous and isotropic cosmologies, similar to those previously obtained in $\text{SU}(2)$-based EPRL-like models. Also in this manifestly Lorentzian setting, in which only continuous $\text{SL}(2,\mathbb{C})$-representations are used, we obtain generalized Friedmann equations that generically exhibit a quantum bounce, and can reproduce all of the features of the cosmological dynamics of EPRL-like models. This lends support to the expectation that the EPRL-like and BC models may lie in the same continuum universality class, and that the quantum gravity mechanism producing effective bouncing scenarios may not depend directly on the discretization of geometric observables.

description: Translations, says Gideon Toury, are facts of target cultures – but the perceived status of source texts has a bearing on how these are reflected or refracted in the target language. This proposition is particularly evident in the case of classics: when translators have to work on literary creations occupying a pivotal position in the source/target cultures, they adopt strategies of literalness and ennoblement which betray a quasi-religious awe – on the one hand, a desire to ruffle the surface of the revered original as little as possible; and on the other, a determination to reproduce the supposed “classical qualities” of the classic even when they are not present in the source. In this dissertation, Paola Venturi studies how the “idea of classic” influences translation theory and practice, and substantiates her theoretical observations by looking at Italian translations of eighteenth- and nineteenth-century English classics. A marked – and historically determined – disparity between source and target readerships, and the translators’ reverence for their prestigious originals, conspire to produce Italian versions which are much more “wooden” and “elegant” than their English counterparts.

description: The study of variability in software development has become increasingly important in recent years. A common mechanism to represent the variability in a product line is by means of feature models. However, the relationship between these models and UML design models is not straightforward. UML statecharts are extended introducing variability in their main components, so that the behavior of product lines can be specified. The contribution of this work is the proposal of a rule-based approach that defines a transformation strategy from extended statecharts to concrete UML statecharts. This is accomplished via the use of feature models, in order to describe the common and variant components, in such a way that, starting from different feature configurations and applying the rule-based method, concrete state machines corresponding to different products of a line can be obtained.

description: A relativistic mean field hadronic model with a dark matter (DM) particle coupled to nucleons including short-range correlations (SRC) is applied to study neutron stars (NS). The lightest neutralino is chosen as the dark particle candidate, which interacts with nucleons by the exchange of Higgs bosons. A detailed thermodynamical analysis shows that the contribution of the DM fermions to the energy density of the matter composed by these particles and nucleons is completely dominated by the DM kinetic terms. The model reproduces satisfactorily the constraints on the mass-radius diagram obtained from the analysis of the combined data from the NICER mission, LIGO and Virgo collaborations, and mass measurements from radio observations. We show that the SRC balance the reduction of the neutron star mass due to the DM component, and because of that the model is able to present more massive NS. We also present a study of the effect, in the NS mass-radius profiles, of the uncertainties in some bulk parameters related to the hadronic sector. We find that it is possible to generate parametrizations, with DM content, compatible with the recent astrophysical constraints and with the uncertainty in the symmetry energy slope obtained from the results reported by the updated Lead Radius EXperiment (PREX-2).

description: So far, various multi-photon entangled states have been observed experimentally by using different experimental set-ups. Here, we present a scheme to realize many SLOCC-inequivalent states of three and four qubits via projective measurements on suitable entangled states. We demonstrate how these states can be observed experimentally in a single set-up and study the feasibility of the implementation with present-day technology.
Mature women students : a survey
Creators: name: Frederickson, Margaret C.
Publisher: name: University of British Columbia
Year: 2010

description: The purpose of this study was to contribute to an understanding of the experience of mature women students who succeeded in completing degrees and diplomas at The University of British Columbia in 1968. Special attention was directed to academic and professional choices, timing of interruptions in formal education, and conflicts experienced by the women as they resumed their studies. Responses to a mail questionnaire were received from 228 women who were 25 years of age or over in 1968 when they completed their degrees or diplomas. The most typical respondent came from relatively favourable socio-economic circumstances, had previous university experience, and returned to formal studies after brief interruption. A small number had returned to studies under difficult conditions, usually with a view to gaining security for themselves and their families. The academic and professional choices of the mature women were more conventionally "feminine" than those of younger women graduates in 1968. Almost half the women had returned to studies for clear-cut economic reasons, and 75.4% of the graduates were working full- or part-time in their specialties. Almost 80.0% of working graduates were employed in teaching or health fields and, except for nurses, were highly satisfied with their jobs. Early interruption in education (for example, at the end of high school) tended to lower horizons for later education, as well as decrease chances of pursuing interests in science and the prestige professions. Maturity and life experience were, however, considered valuable assets in continuing formal studies. Many respondents considered themselves "pioneers" in continuing their studies in an atmosphere which was non-supportive to mature women students. The conflict between stereotyped feminine roles and higher education for women was clearly felt by one-third of the women, even in this population which made largely conventional academic choices. The survey presents a picture of well-adjusted, purposeful women who achieved their academic goals without the help of a community college system since established, and the somewhat increased financial and part-time study opportunities which later became available. The conclusion is that only those who enjoyed some advantages or who were willing to undergo heavy stress - or both - were able to succeed in the mid-1960's.

description: Systematic errors in qubit state preparation arise due to non-idealities in the qubit control lines such as impedance mismatch. Using a data-based methodology of short-open-load calibration at a temperature of 30 mK, we report calibrated 1-port scattering parameter data of individual qubit drive line components. At 5~GHz, cryogenic return losses of a 20-dB-attenuator, 10-dB-attenuator, a 230-mm-long 0.86-mm silver-plated cupronickel coaxial cable, and a 230-mm-long 0.86-mm NbTi coaxial cable were found to be 35$^{+3}_{-2}$ dB, 33$^{+3}_{-2}$ dB, 34$^{+3}_{-2}$ dB, and 29$^{+2}_{-1}$ dB respectively. For the same frequency, we also extract cryogenic insertion losses of 0.99$^{+0.04}_{-0.04}$ dB and 0.02$^{+0.04}_{-0.04}$ dB for the coaxial cables. We interpret the results using a master equation simulation of all XY gates performed on a single qubit. For example, we simulate a sequence of two 5 ns gate pulses (X & Y) through a 2-element Fabry-Pérot cavity with 276-mm path length directly preceding the qubit, and establish that the return loss of its reflective elements must be >9.7 dB (> 14.7 dB) to obtain 99.9 % (99.99 %) gate fidelity.

description: Hybrid exchange-correlation functionals provide superior electronic structure and optical properties of semiconductors or insulators as compared to semilocal exchange-correlation potentials due to admixing a portion of the non-local exact exchange potential from a Hartree-Fock theory. Since the non-local potential does not commute with the position operator, the momentum matrix elements do not fully capture the oscillator strength, while the length-gauge velocity matrix elements do. So far, length-gauge velocity matrix elements were not accessible in the all-electron full-potential WIEN2k package. We demonstrate the feasibility of computing length-gauge matrix elements in WIEN2k for a hybrid exchange-correlation functional based on a finite difference approach. To illustrate the implementation we determined matrix elements for optical transitions between the conduction and valence bands in GaAs, GaN, (CH$_3$NH$_3$)PbI$_3$ and a monolayer MoS$_2$. The non-locality of the Hartree-Fock exact exchange potential leads to a strong enhancement of the oscillator strength as noticed recently in calculations employing pseudopotentials [Laurien and Rubel: arXiv:2111.14772 (2021)]. We obtained an analytical expression for the enhancement factor in terms of the difference in eigenvalues not captured by the kinetic energy. It is expected that these results can also be extended to other non-local potentials, e.g., a many-body $GW$ approximation.

Structured learning of safety guarantees for the control of uncertain dynamical systems

description: Approaches to keeping a dynamical system within state constraints typically rely on a model-based safety condition to limit the control signals. In the face of significant modeling uncertainty, the system can suffer from important performance penalties due to the safety condition becoming overly conservative. Machine learning can be employed to reduce the uncertainty around the system dynamics, and allow for higher performance. In this article, we propose the safe uncertainty learning principle, and argue that the learning must be properly structured to preserve safety guarantees. For instance, robust safety conditions are necessary, and they must be initialized with conservative uncertainty bounds prior to learning. Also, the uncertainty bounds should only be tightened if the collected data sufficiently capture the future system behavior. To support the principle, two example problems are solved with control barrier functions: a lane-change controller for an autonomous vehicle, and an adaptive cruise controller. This work offers a way to evaluate if machine learning preserves safety guarantees during the control of uncertain dynamical systems. It also highlights challenging aspects of learning for control.

description: In ordinary statistical mechanics the Boltzmann-Shannon entropy is related to the Maxwell-Bolzmann distribution $p_i$ by means of a twofold link. The first link is differential and is offered by the Jaynes Maximum Entropy Principle. The second link is algebraic and imposes that both the entropy and the distribution must be expressed in terms of the same function in direct and inverse form. Indeed, the Maxwell-Boltzmann distribution $p_i$ is expressed in terms of the exponential function, while the Boltzmann-Shannon entropy is defined as the mean value of $-\ln(p_i)$. In generalized statistical mechanics the second link is customarily relaxed. Here we consider the question if and how is it possible to select generalized statistical theories in which the above mentioned twofold link between entropy and the distribution function continues to hold, such as in the case of ordinary statistical mechanics. Within this scenario, there emerge new couples of direct-inverse functions, i.e. generalized logarithms $Λ(x)$ and generalized exponentials $Λ^{-1}(x)$, defining coherent and self-consistent generalized statistical theories. Interestingly, all these theories preserve the main features of ordinary statistical mechanics, and predict distribution functions presenting power-law tails. Furthermore, the obtained generalized entropies are both thermodynamically and Lesche stable.
