description: Ord's kangaroo rats in Alberta occupy natural habitat which is typified by sand dunes and sandy river-valley slopes, and anthropogenic habitat in the form of sandy roads and fireguards. I studied differences in predation risk, winter microclimate, body condition, and over-winter survival of Ord's kangaroo rats in natural and anthropogenic habitat. Kangaroo rats in anthropogenic habitat appear to be at higher risk of predation than those in natural habitats. Kangaroo rats occupy burrow sites that maximize winter solar radiation, and winter soil temperatures in kangaroo rat burrow locations are colder in anthropogenic habitat than natural habitat. Kangaroo rats in anthropogenic habitat had lower fall body condition than in natural habitat, and body condition was positively correlated with adult over-winter survival. Over-winter survival rates were higher in river valley sites than dunes or roads. My results suggest numerous, potentially cumulative, negative implications for kangaroo rats occupying anthropogenic habitats.

description: The article examines the specifics of the constructive analysis of the English sentence and the strategy of its translation into Russian. The author draws attention to the fact that the expansion of the main and secondary members of the English sentence leads to difficulties in translating them into Russian. In most cases, it is possible to preserve the syntactic constructions of sentences. However, the existing differences in the grammar of the English and Russian languages necessitate the correct choice of translation strategies. Using the examples of the Englishlanguage literary texts and journalistic materials with the author’s translation, the article shows that changes in the constructions of English sentences occur when using strategies of antonymous translation, concretization, generalization, compensation and modulation (semantic development). Literal translation allows one to preserve the syntactic and grammatical structures of English sentences with the expansion and complication of the main and subordinate parts

description: We outline the approach being developed in the neuGRID project to use provenance management techniques for the purposes of capturing and preserving the provenance data that emerges in the specification and execution of workflows in biomedical analyses. In the neuGRID project a provenance service has been designed and implemented that is intended to capture, store, retrieve and reconstruct the workflow information needed to facilitate users in conducting user analyses. We describe the architecture of the neuGRID provenance service and discuss how the CRISTAL system from CERN is being adapted to address the requirements of the project and then consider how a generalised approach for provenance management could emerge for more generic application to the (Health)Grid community.

Electrically tunable exchange splitting in bilayer graphene on monolayer Cr2X2Te6 with X = Ge, Si, and Sn

description: We investigate the electronic band structure and the proximity exchange effect in bilayer graphene (BLG) on a family of ferromagnetic multilayers Cr2X2Te6, X = Ge, Si, and Sn, with first principles methods. In each case the intrinsic electric field of the heterostructure induces an orbital gap on the order of 10 meV in the graphene bilayer. The proximity exchange is strongly band-dependent. For example, in the case of Cr2Ge2Te6, the low energy valence band of BLG has exchange splitting of 8 meV, while the low energy conduction band's splitting is 30 times less (0.3 meV). This striking discrepancy stems from the layer-dependent hybridization with the ferromagnetic substrate. Remarkably, applying a vertical electric field of a few V nm–1 reverses the exchange, allowing us to effectively turn ON and OFF proximity magnetism in BLG. Such a field-effect should be generic for van der Waals bilayers on ferromagnetic insulators, opening new possibilities for spin-based devices.
On the interactions between naphthenic acids and inorganic minerals
Creators: name: Nodwell, Maximilian
Publisher: name: University of British Columbia
Year: 2011

description: Naphthenic acids are a family of carboxylic acids that are found in oil sands bitumen. These compounds partition to the aqueous phase during extraction and refining and are toxic to various biota. The removal of these acids from solution is difficult due to their low concentrations, complexity of the mixture and poor understanding of the behaviour of the mixed compounds. In particular, partitioning of these organic acids to solid surfaces is not well understood. Knowledge of this equilibria would be helpful for potential process development. The research presented here describes the adsorption of two surrogate naphthenic acids onto inorganic minerals (copper sulphide and copper hydroxide). Decanoic acid and cyclohexane pentanoic acid were found to be insoluble in water at pH 3, leading to hydrophobic adsorption onto the minerals and the reaction vessel surfaces. At pH 8.5, both acids formed insoluble copper-carboxylate complexes when mixed with the minerals. The hypothesized 2:1 acid:copper stoichiometry was confirmed. The mechanism of complexation varied with the reaction conditions; both chelating and bridging complexes were observed in the resultant metallo-organic solids. The relative hydrophobicity of the two NA surrogates was also found to contribute to the different adsorption trends. During the pH 8.5 reactions, the solution pHs were found to drop. The uncontrolled decreases in pH had significant effect on the water-solid partition and on the apparent mineral loading of the organics. It appears that soluble copper cations have a higher extent of reaction with the carboxylate anions than does copper contained in the mineral solids. Quantification of these reactions is difficult; however this research does enable conclusions about how the organic acids and inorganic minerals interact and sets the stage for future research.

description: In the quest for efficiency and performance, edge-computing providers replace process isolation with sandboxes, to support a high number of tenants per machine. While secure against software vulnerabilities, microarchitectural attacks can bypass these sandboxes. In this paper, we present a Spectre attack leaking secrets from co-located tenants in edge computing. Our remote Spectre attack, using amplification techniques and a remote timing server, leaks 2 bit/min. This motivates our main contribution, DyPrIs, a scalable process-isolation mechanism that only isolates suspicious worker scripts following a lightweight detection mechanism. In the worst case, DyPrIs boils down to process isolation. Our proof-of-concept implementation augments real-world cloud infrastructure used in production at large scale, Cloudflare Workers. With a false-positive rate of only 0.61 %, we demonstrate that DyPrIs outperforms strict process isolation while statistically maintaining its security guarantees, fully mitigating cross-tenant Spectre attacks.
CPU Port Contention Without SMT

description: CPU port contention has been used in the last years as a stateless side channel to perform side-channel attacks and transient execution attacks. One drawback of this channel is that it heavily relies on simultaneous multi-threading, which can be absent from some CPUs or simply disabled by the OS. In this paper, we present sequential port contention, which does not require SMT. It exploits sub-optimal scheduling to execution ports for instruction-level parallelization. As a result, specifically-crafted instruction sequences on a single thread suffer from an increased latency. We show that sequential port contention can be exploited from web browsers in WebAssembly. We present an automated framework to search for instruction sequences leading to sequential port contention for specific CPU generations, which we evaluated on 50 different CPUs. An attacker can use these sequences from the browser to determine the CPU generation within 12 second with a 95% accuracy. This fingerprint is highly stable and resistant to system noise, and we show that mitigations are either expensive or only probabilistic.

description: The research presented in this thesis describes the feasibility and acceptability of a longitudinal program in communication skills for neurology residents, and the program's design and implementation. It also explores neurologists' perspectives on communication skills locally and nationally. Data were abstracted from qualitative and quantitative sources. The results of this work demonstrate that it is possible to sustain a comprehensive communication skills program that is well-received by the participants, and that the program impacts how residents think about their communication skills in their day to day work. In the broader context of Canadian Neurology Training, it appears that few residency programs have communication curricula, and that this relates to program directors' perceptions that these curricula may not be necessary or possible. Local faculty members expressed similar views, which is in keeping with the finding that few faculty members were available to participate in the program in Calgary.

description: Аннотация: проведены экспериментальные исследования по отводу теплоты реакции при контакте углекислого газа с очищенным рассолом. Для эффективного проведения использованы трубы с развитой поверхностью теплообмена, образованные спиральными канавками снаружи и аналогичными выступами внутри труб. Опыты проведены на гладкой и четырех трубах с различным шагом и глубиной канавок, т.е h/S=0,017-0,095. Исследованиями по интенсификации конвективного теплообмена при омывании пучка спирально-накатанных труб газожидкостным потока установлено повышение переноса тепла в 1,8-2,7 раза по сравнению с гладкой трубой. Столь высокая интенсификация позволяет сделать трубчато решетчатые насадки более компактными при сохранении тепловой нагрузки. Опытные данные обобщены и получена критериальная формула для расчета интенсивности теплообмена при течении газожидкостного потока в межтрубном пространстве. Полученные результаты можно использовать при расчете и проектировании колонных аппаратов, в которых происходит выделение тепла реакции при контакте фаз.

description: We present event-by-event viscous hydrodynamic calculations of the anisotropic flow coefficients v_2 to v_5 for heavy-ion collisions at the Relativistic Heavy-Ion Collider (RHIC). We study the dependence of different flow harmonics on shear viscosity and the morphology of the initial state. v_3 and higher flow harmonics exhibit a particularly strong dependence on both the initial granularity and shear viscosity. We argue that a combined analysis of all available flow harmonics will allow to determine eta/s of the quark gluon plasma precisely. Presented results strongly hint at a value (eta/s)_QGP < 2/4pi at RHIC. Furthermore, we demonstrate the effect of shear viscosity on pseudo-rapidity spectra and the mean transverse momentum as a function of rapidity.

Freely Given Consent? Studying Consent Notice of Third-Party Tracking and Its Violations of GDPR in Android Apps

description: Adopted in May 2018, the European Union's General Data Protection Regulation (GDPR) requires the consent for processing users' personal data to be freely given, specific, informed, and unambiguous. While prior work has shown that this often is not given through automated network traffic analysis, no research has systematically studied how consent notices are currently implemented and whether they conform to GDPR in mobile apps. To close this research gap, we perform the first large-scale study into consent notices for third-party tracking in Android apps to understand the current practices and the current state of GDPR's consent violations. Specifically, we propose a mostly automated and scalable approach to identify the currently implemented consent notices and apply it to a set of 239,381 Android apps. As a result, we recognize four widely implemented mechanisms to interact with the consent user interfaces from 13,082 apps. We then develop a tool that automatically detects users' personal data sent out to the Internet with different consent conditions based on the identified mechanisms. Doing so, we find 30,160 apps do not even attempt to implement consent notices for sharing users' personal data with third-party data controllers, which mandate explicit consent under GDPR. In contrast, out of 13,082 apps implemented consent notices, we identify 2,688 (20.54%) apps violate at least one of the GDPR consent requirements, such as trying to deceive users into accepting all data sharing or even continuously transmitting data when users have explicitly opted out. To allow developers to address the problems, we send emails to notify affected developers and gather insights from their responses. Our study shows the urgent need for more transparent processing of personal data and supporting developers in this endeavor to comply with legislation, ensuring users can make free and informed choices regarding their data.

description: I compute the Lorentzian EPRL/FK/KKL spinfoam vertex amplitude for regular graphs, with an arbitrary number of links and nodes, and coherent states peaked on a homogeneous and isotropic geometry. This form of the amplitude can be applied for example to a dipole with an arbitrary number of links or to the 4-simplex given by the compete graph on 5 nodes. All the resulting amplitudes have the same support, independently of the graph used, in the large j (large volume) limit. This implies that they all yield the Friedmann equation: I show this in the presence of the cosmological constant. This result indicates that in the semiclassical limit quantum corrections in spinfoam cosmology do not come from just refining the graph, but rather from relaxing the large j limit.

description: The Lottery Ticket Hypothesis continues to have a profound practical impact on the quest for small scale deep neural networks that solve modern deep learning tasks at competitive performance. These lottery tickets are identified by pruning large randomly initialized neural networks with architectures that are as diverse as their applications. Yet, theoretical insights that attest their existence have been mostly focused on deep fully-connected feed forward networks with ReLU activation functions. We prove that also modern architectures consisting of convolutional and residual layers that can be equipped with almost arbitrary activation functions can contain lottery tickets with high probability.

The article describes the main structural elements of the stock market, the basic principles and objectives of exchange work. The main issues of the securities market are highlighted. An assessment of the current state of the stock market regulation system in Ukraine has been made. Characteristic features of the current state of the Ukrainian securities market regulation system are: underdeveloped technical and functional infrastructure subsystems inhibit market development, lack of an effective regulatory system for self-regulatory organizations and inefficiency of trade control and regulatory systems in the securities markets. It is emphasized that the stock market plays a major role in the redistribution of national resources and is therefore necessary for the successful development of a market economy. Restoration, regulation and development of the stock market and its infrastructure are of paramount importance to the government.

Infrared excess around nearby RGB stars and Reimers law

Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)

description: (Abridged) The spectral energy distributions of a well-defined sample of 54 RGB stars are constructed, and fitted with the dust radiative transfer model DUSTY. The central stars are modeled by MARCS model atmospheres. In a first step, the best-fit MARCS model is derived, determining the effective temperature. In a second step, models with a finite dust optical depth are fitted and it is determined whether the reduction in chi2 in such models with one additional free parameter is statistically significant. 23 stars are found to have a significant infrared excess, which is interpreted as mass loss. The dust optical depths are translated into mass-loss rates assuming a typical expansion velocity of 10 km/s and a dust-to-gas ratio of 0.005. The mass-loss rates are compared to those derived for luminous stars in globular clusters, by fitting both the infrared excess, as in the present paper, and the chromospheric lines. There is excellent agreement between these values and the mass-loss rates derived from the chromospheric activity. There is a systematic difference with the literature mass-loss rates derived from modeling the infrared excess, and this has been traced to technical details on how the DUSTY radiative transfer model is run. If the present results are combined with those from modeling the chromospheric emission lines, we obtain the fits Log Mdot = (1.0 +- 0.3) Log L + (-12.0 +- 0.9) and Log Mdot = (0.6 +- 0.2) Log (LR/M) + (-11.9 +- 0.9). The predictions of these mass-loss rate formula are tested against the RGB mass loss determination in NGC 6791. Using a scaling factor of (8 +- 5), both relations can fit this value. That the scaling factor is larger than unity suggests that the expansion velocity and/or dust-to-gas ratio, or even the dust opacities, are different from the values adopted.
description: It was pointed out that the mass used for NGC 6719 is incorrect (its 1.2 and not 1.6 Msol). The numbers in table 6 are correct, but the inference drawn from it not. The result is that the scaling factors eta_1 and eta_2 become slightly smaller. The conclusions of the paper remain unchanged. This version has the updated Table 6 and eta's. These changes will appear as an erratum to the A&A paper

description: We present the first detailed imaging and spatially resolved spectroscopic study of the Galactic supernova remnant G292.2-0.5, associated with the high-magnetic field radio pulsar J1119-6127, using Chandra and XMM-Newton. The high-resolution X-ray images reveal a partially limb-brightened morphology in the west, with diffuse emission concentrated towards the interior of the remnant unlike the complete shell-like morphology observed at radio wavelengths. The spectra of most of the diffuse emission regions within the remnant are best described by a thermal+non-thermal model. The thermal component is described by a plane-parallel, non-equilibrium ionization plasma model with a temperature ranging from 1.3 keV in the western side of the remnant to 2.3 keV in the east, a column density increasing from 1.0e22 cm^-2 in the west to 1.8e22 cm^-2 in the east, and a low ionization timescale ranging from 5.7e9 cm^-3 s in the SNR interior to 3.6e10 cm^-3 s in the western side - suggestive of expansion of a young remnant in a low-density medium. The spatial and spectral differences across the SNR are consistent with the presence of a dark cloud in the eastern part of the SNR, absorbing the soft X-ray emission. The spectra from some of the regions also show slightly enhanced metal abundances from Ne, Mg and Si, hinting at the first evidence for ejecta heated by the reverse shock. Comparing our inferred metal abundances to core-collapse nucleosynthesis models yields, we estimate a high progenitor mass of ~30 solar mass suggesting a type Ib/c supernova. We confirm the presence of non-thermal hard X-ray emission from regions close to the pulsar. We estimate an SNR age range between 4.2 kyr (free expansion phase) and 7.1 kyr (Sedov phase), a factor of a few higher than the measured pulsar's age upper limit of 1.9 kyr.

description: This Letter, i.e. for the first time, proves that a general invariant velocity is originated from the principle of special relativity, namely, discovers the origin of the general invariant velocity, and when the general invariant velocity is taken as the invariant light velocity in current theories, we get the corresponding special theory of relativity. Further, this Letter deduces triple special theories of relativity in cosmology, and cancels the invariant presumption of light velocity, it is proved that there exists a general constant velocity K determined by the experiments in cosmology, for K > 0, = 0 and < 0, they correspond to three kinds of possible relativistic theories in which the special theory of relativity is naturally contained for the special case of K > 0, and this Letter gives a prediction that, for K < 0, there is another likely case satisfying the principle of special relativity for some special physical systems in cosmology, in which the relativistic effects observed would be that the moving body would be lengthened, moving clock would be quickened. And the point of K = 0 is a bifurcation point, through which it gives out three types of possible universes in the cosmology (or multiverse). When a kind of matter with the maximally invariant velocity that may be superluminal or equal to light velocity is determined by experiments, then the invariant velocity can be taken as one of the general invariant velocity achieved in this Letter, then all results of current physical theories are consistent by utilizing this Letter's theory.

A kinetic study of decalin selective ring opening reactions over Iridium supported on H-Beta zeolite catalyst

Publisher: name: University of British Columbia
Year: 2011

description: Selective ring opening of naphthenic rings is the optimum process for reducing the cyclo-paraffin and aromatic content of gas oils in order to improve its quality and consequently its value. The aim of this study was to examine the reaction rates of ring opening of a model multi-ring compound, namely decalin, using a bifunctional catalyst. Three catalysts, Pd/H-Y-30, Ir/H-Beta-300 and Ir/H-Beta-25, were tested to examine the activity and yield of ring opened products at the same reaction conditions. The reaction was performed in a continuously-stirred, batch reactor at 350°C and 3 MPa H₂ pressure. The results showed that Ir/H-Beta-25 had the highest activity and yield of ring opened products. By comparing the Ir/H-Beta-25 catalyst and the Ir/H-Beta-350 catalyst, it was concluded that higher activity was achieved with higher acidity, confirming the important role of catalyst acidity in selective ring opening. The effect of reaction conditions, namely temperature (275-350°C) and pressure (3-6 MPa), on the activity and product selectivity was also investigated. Results showed that as the temperature increased, the initial catalyst activity increased. Although the effect of pressure was minimal at 275°C, as the temperature increased, the effect of pressure became more significant and higher conversions were achieved at higher pressures. The concentration of ring opened products increased as the conversion increased for all temperatures and pressures. The ring opened product concentrations increased with increased temperature at 3 MPa. At 275°C, higher ring opened product concentrations were obtained at higher conversions as the pressure increased. Based on the experimental results, a Langmuir Hinshelwood (L-H) kinetic model for the ring opening of decalin was developed. The kinetic model assumed a bifunctional catalytic process in which hydrogenation/dehydrogenation reactions occurred on metal sites, whereas isomerization, ring-opening and cracking occurred on acid sites. The model parameters were estimated by minimizing the difference between measured experimental data and model predictions by the sum of least-squares method. The model was able to estimate the experimental results well, with a R₂ of 0.8. Activation energies estimated from the model parameters showed that ring opening had the lowest activation energy (135.4 kJ/mol), whereas cracking had the highest (229.7 kJ/mol).
SFLKit: A Workbench for Statistical Fault Localization

description: Statistical fault localization aims at detecting execution features that correlate with failures, such as whether individual lines are part of the execution. We introduce SFLKit, an out-of-the-box workbench for statistical fault localization. The framework provides straight- forward access to the fundamental concepts of statistical fault lo- calization. It supports five predicate types, four coverage-inspired spectra, like lines, and 38 similarity coefficients, e.g., TARANTULA or OCHIAI, for statistical program analysis. SFLKit separates the execution of tests from the analysis of the re- sults and is therefore independent of the used testing framework. It leverages program instrumentation to enable the logging of events and derives the predicates and spectra from these logs. This instru- mentation allows for introducing multiple programming languages and the extension of new concepts in statistical fault localization. Currently, SFLKit supports the instrumentation of python programs. SFLKit is highly configurable, requiring only the logging of the re- quired events.

description: Приводятся устойчивые алгоритмы адаптивного управления, оценивания параметров регулятора, синтеза процедуры адаптивного управления динамическими объектами по критерию минимума дисперсии и синтеза субоптимального адаптивно-локального управления динамическими объектами на основе прогнозирующих моделей. Приведены алгоритмы устойчивой идентификации динамических объектов управления на основе методов регуляризации и псевдообращения, основанные на сингулярном разложении. На основе использования аппроксимаций в виде конечной суммы гауссовских распределений разработаны алгоритмы рекуррентной идентификации с помощью множественных моделей и адаптации их параметров. Предложены устойчивые алгоритмы идентификация параметров объекта и регулятора в замкнутой системе управления на основе принципа итеративной регуляризации с привлечением метода вариационных неравенств, обеспечивающие сходимость искомых оценок параметров объекта и регулятора почти наверное к истинным значениям. Предложены устойчивые алгоритмы формирования управляющих воздействий в локально-оптимальных адаптивных системах управления динамическими объектами на основе неортогональных факторизациях и псевдообращениях плохообусловленных или вырожденных квадратных матриц, способствующие повышению точности формирования управляющих воздействий в замкнутом контуре управления.

description: ΣΚΟΠΟΣ: Τα σεξεργαζόμενα άτομα εκτίθενται σε πολλαπλούς κινδύνους για την υγεία και την ασφάλεια τους, στην εργασία τους ενώ ταυτόχρονα φέρουν πολλαπλές και διαφορετικές ταυτότητες. Σκοπός αυτής της μελέτης είναι να καταγραφούν οι εμπειρίες, οι αντιλήψεις και οι πρακτικές τους σχετικά με την υγεία και την πρόσβαση στις υπηρεσίες υγείας, με απώτερο στόχο τη βαθύτερη κατανόηση των συνθηκών σεξεργασίας, των κινδύνων και των εμποδίων που αντιμετωπίζουν καθώς και τις πιθανές λύσεις. ΜΕΘΟΔΟΣ: Χρησιμοποιήθηκαν δύο ερευνητικά εργαλεία, η ανασκόπηση της βιβλιογραφίας με σκοπό την ανάλυση των σχετικών ερευνών και η ποιοτική έρευνα μέσω ημιδομημένων συνεντεύξεις με 10 σεξεργαζόμενα άτομα. ΑΠΟΤΕΛΕΣΜΑΤΑ: Τα αποτελέσματα της μελέτης έδειξαν ότι τα σεξεργαζόμενα άτομα που συμμετείχαν νιώθουν σχετικά ικανοποιημένα με την υγεία τους, αλλά θεωρούν πως η οικονομική τους κατάσταση είναι σχετικά κακή, και τα μηνιαία έσοδα δεν φτάνουν για να καλύψουν τις ανάγκες τους. Στην πλειονότητα τους προσφέρουν υπηρεσίες μόνο με προφύλαξη παρότι ένα μεγάλο κομμάτι των πελατών ζητάει χωρίς. Σχεδόν όλοι νιώθουν καλά με τον εαυτό τους σε σχέση με την εργασία τους παρότι θεωρούν πώς είναι ένα στιγματισμένο επάγγελμα. Όλοι αναφέρουν άσχημες και κακοποιητικές συμπεριφορές από πελάτες κυρίως λεκτικής και ψυχολογικής φύσεως. Αρκετοί συνεντευξιαζόμενοι δεν θεωρούν πώς η σεξεργασία είναι επικίνδυνη για την υγεία τους. Κάνουν συχνά εξετάσεις για ΣΜΛ παρότι αντιμετωπίζουν δυσκολίες και κανένα άτομο δεν πάσχει από κάποια. Τα σημαντικότερα προβλήματα που αντιμετωπίζουν είναι η έλλειψη ασφάλισης και οι φοβικές αντιδράσεις. Έτσι αποκρύπτουν το επάγγελμα τους. Παρά τα αρκετά περιστατικά διακρίσεων που αναφέρθηκαν, κανένα άτομο δεν έχει προβεί σε καταγγελία. Η πανδημία του COVID-19 φαίνεται να έχει επηρεάσει τόσο την καθημερινή ζωή όσο και την επιβίωση και την υγεία. ΣΥΜΠΕΡΑΣΜΑΤΑ: Η πλήρης αποποινικοποίηση της σεξεργασίας και το νόμιμο εργασιακό περιβάλλον είναι ίσως η βασικότερη απαίτηση των ίδιων των σεξεργαζόμενων ατόμων. Η θεώρηση της σεξεργασίας ως εργασίας θα αλλάξει τη σχέση των εργαζομένων με το κράτους, τους θεσμούς, τις υπηρεσίες υγείας, την αστυνομία αλλά και την κοινωνία στο σύνολο της. Επιπλέον θα δημιουργηθούν οι κατάλληλες συνθήκες εργασίας που θα μειώσουν την ευπάθεια των εργαζομένων αυτών (σε ΣΜΛ, χρήση ουσιών, βία κ.α.).

description: Приводятся алгоритмы формирования процедуры устойчивого оценивания матриц параметров и ковариаций векторов возмущений в неопределенных динамических системах на основе концепций псевдообращения матриц. Для устойчивого псевдообращения используется метод разбиения матрицы на блоки с использованием упрощенной регуляризации. Приведенные алгоритмы позволяют производить устойчивое оценивание матриц параметров и ковариаций векторов возмущений в динамических системах и тем самым повысить точность систем адаптивного управления, функционирующих в условиях параметрической и сигнальной неопределенности.

description: I will survey some matters of relevance to a philosophical discussion of information, taking into account developments in algorithmic information theory (AIT). I will propose that meaning is deep in the sense of Bennett's logical depth, and that algorithmic probability may provide the stability needed for a robust algorithmic definition of meaning, one that takes into consideration the interpretation and the recipient's own knowledge encoded in the story attached to a message.

description: Locally Checkable Labeling (LCL) problems are graph problems in which a solution is correct if it satisfies some given constraints in the local neighborhood of each node. Example problems in this class include maximal matching, maximal independent set, and coloring problems. A successful line of research has been studying the complexities of LCL problems on paths/cycles, trees, and general graphs, providing many interesting results for the LOCAL model of distributed computing. In this work, we initiate the study of LCL problems in the low-space Massively Parallel Computation (MPC) model. In particular, on forests, we provide a method that, given the complexity of an LCL problem in the LOCAL model, automatically provides an exponentially faster algorithm for the low-space MPC setting that uses optimal global memory, that is, truly linear. While restricting to forests may seem to weaken the result, we emphasize that all known (conditional) lower bounds for the MPC setting are obtained by lifting lower bounds obtained in the distributed setting in tree-like networks (either forests or high girth graphs), and hence the problems that we study are challenging already on forests. Moreover, the most important technical feature of our algorithms is that they use optimal global memory, that is, memory linear in the number of edges of the graph. In contrast, most of the state-of-the-art algorithms use more than linear global memory. Further, they typically start with a dense graph, sparsify it, and then solve the problem on the residual graph, exploiting the relative increase in global memory. On forests, this is not possible, because the given graph is already as sparse as it can be, and using optimal memory requires new solutions.

description: Bone is a biomaterial undergoing continuous renewal. The renewal process is known as bone remodelling and is operated by bone-resorbing cells (osteoclasts) and bone-forming cells (osteoblasts). Both biochemical and biomechanical regulatory mechanisms have been identified in the interaction between osteoclasts and osteoblasts. Here we focus on an additional and poorly understood potential regulatory mechanism of bone cells, that involves the morphology of the microstructure of bone. Bone cells can only remove and replace bone at a bone surface. However, the microscopic availability of bone surface depends in turn on the ever-changing bone microstructure. The importance of this geometrical dependence is unknown and difficult to quantify experimentally. Therefore, we develop a sophisticated mathematical model of bone cell interactions that takes into account biochemical, biomechanical and geometrical regulations. We then investigate numerically the influence of bone surface availability in bone remodelling within a representative bone tissue sample. The interdependence between the bone cells' activity, which modifies the bone microstructure, and changes in the microscopic bone surface availability, which in turn influences bone cell development and activity, is implemented using a remarkable experimental relationship between bone specific surface and bone porosity. Our model suggests that geometrical regulation of the activation of new remodelling events could have a significant effect on bone porosity and bone stiffness. On the other hand, geometrical regulation of late stages of osteoblast and osteoclast differentiation seems less significant. We conclude that the development of osteoporosis is probably accelerated by this geometrical regulation in cortical bone, but probably slowed down in trabecular bone.
