description: Anti-apoptotic proteins play a fundamental role in cell survival. Under physiological conditions, such proteins trigger apoptosis in defective or damaged cells only; under pathological conditions, however, they can be dysregulated allowing the cells to survive despite being harmful. Considering the importance of anti-apoptotic proteins in many physio-pathological roles, their specific inhibition is an attractive strategy to develop safe therapeutics. This thesis describes the inhibition of two classes of anti-apoptotic proteins: 1) Inhibition of the anti-apoptotic protein CK2 to develop novel anti-cancer molecules targeting pockets outside the well-conserved ATP-binding site: -Using a Fragment-Based-Drug-Discovery (FBDD) approach twelve small molecule inhibitors of CK2 were developed. The lead molecule, 3l, inhibited the catalytic activity of CK2α by binding in the cryptic αD pocket with a Kd of 4 μM. 3l stopped proliferation of colorectal cancer cells with a GI50 of 10 μM and presented improved drug-like properties and selectivity compared to previously reported inhibitors. Remarkably, 3l has the potential to be developed into a potent and selective anticancer drug. -Using a combination of rational-based approach and peptide stapling, twenty-two conformationally-constrained peptides were generated to target the protein-protein interaction (PPI) of CK2 and affect its function. The lead peptide, P7-F1C5, presented a novel, highly-functionalised constraint that allowed the molecule to become cell-permeable, exert its anti-proliferative activity in cancerous cells, and to become resistant to serum proteases. P7-F1C5 is the first macromolecule reported in the literature that binds to CK2α with sub-micromolar affinity (Kd 150 nM), and that can act as a chemical probe for targeting the PPI of CK2. 2) Inhibition of the anti-apoptotic Bcl-2 proteins to dissect their role in platelet activation and apoptosis. Bcl-2 proteins regulate cell lifespan; however, their role in non-nucleated platelets is not fully understood. The elucidation of these pathways in platelets is crucial to the development of selective anti-platelet therapeutics. To this end, this thesis describes the development and the first application of twenty-seven BH3-only peptides in human platelets highlighting how peptides can provide an alternative to conventional methodologies to study PPIs in platelets. The most promising peptide, P9-F5C5, engaged the anti-apoptotic protein Bcl-xL with 26 nM affinity and reviled a new role for the protein Bim in platelet activation.

description: We imaged the error box of a gamma-ray burst of the short (0.5 s), hard type (GRB 000313), with the BOOTES-1 experiment in southern Spain, starting 4 min after the gamma-ray event, in the I-band. A bright optical transient (OT 000313) with I = 9.4 +/- 0.1 was found in the BOOTES-1 image, close to the error box (3-sigma) provided by BATSE. Late time VRIK'-band deep observations failed to reveal an underlying host galaxy. If the OT 000313 is related to the short, hard GRB 000313, this would be the first optical counterpart ever found for this kind of events (all counterparts to date have been found for bursts of the long, soft type). The fact that only prompt optical emission has been detected (but no afterglow emission at all, as supported by theoretical models) might explain why no optical counterparts have ever been found for short, hard GRBs.This fact suggests that most short bursts might occur in a low-density medium and favours the models that relate them to binary mergers in very low-density enviroments.

description: The main aim of the article was an analysis of the significance of imports in the supply of material for the Polish and German agri-food sectors. The results of the analysis point to the fact that foreign trade is an important factor stabilising the development of the food sector in Poland and in Germany. However, in Germany imports are a much stronger stimulator of the development of agriculture and food industry than in Poland. A comparison reveals the desirable direction of changes in Poland, where the role of imports in the supply of materials to agriculture and the food industry should increase. Thanks to this, the imported products and global processes will have a significant influence on further development and modernisation of the Polish agribusiness.
An Experimental and Theoretical Investigation into Mg-ion Battery Electrodes using Nuclear Magnetic Resonance Spectroscopy

description: This thesis presents a combined experimental and theoretical approach on studying Mg-ion battery electrode materials, where Nuclear Magnetic Resonance (NMR) spectroscopy plays a central role in identifying the local structure and dynamics of the magnesium ions. Density Functional Theory (DFT) techniques are used extensively to (i) calculate and rationalise the observed NMR shifts, (ii) provide insights into the dynamics involved in such electrode materials, and (iii) guide the synthesis of candidate electrode materials. This work begins by a systematic study of 25Mg solid-state NMR in paramagnetic oxides, where the presence of transition metals makes them suitable for applications in high-voltage cathode materials. DFT methods for predicting and rationalising the paramagnetic NMR shifts are developed, with experimental verifications on synthesised samples. Feasibility of using advanced NMR pulse sequences such as Rotor-Assisted Population Transfer and Magic Angle Turning is demonstrated on such systems to afford enhanced resolution and sensitivity. This approach of combined NMR and DFT techniques is then applied to two of magnesium vanadates for high-voltage cathode applications. In particular, DFT-based thermodynamic energies are used to rationally design the synthetic steps leading to the said vanadate materials, followed by DFT prediction of the migration barriers. The prepared material was subject to experimental characterisation using NMR and diffraction techniques, with an initial cycling data in an electrochemical cell. In the final part, a combined experimental and ab initio investigation on Mg3Bi2, a promising Mg-ion battery anode material, is presented. Previous reports on variable-temperature 25Mg NMR spectroscopy is validated by DFT calculations on the migration barrier and defect energetics. Mechanistic insights on the migration mechanism are presented using the hybrid eigenvector-following transition state searching method, where the relativistic effects of heavy bismuth is shown to influence the migration barrier. We show that the defect formation energy of a Mg vacancy is critical in the apparent Mg diffusion barrier, which is heavily influenced by sample preparation conditions.

Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

description: Machine learning with deep neural networks ("deep learning") allows for learning complex features directly from raw input data, completely eliminating hand-crafted, "hard-coded" feature extraction from the learning pipeline. This has lead to state-of-the-art performance being achieved across several---previously disconnected---problem domains, including computer vision, natural language processing, reinforcement learning and generative modelling. These success stories nearly universally go hand-in-hand with availability of immense quantities of labelled training examples ("big data") exhibiting simple grid-like structure (e.g. text or images), exploitable through convolutional or recurrent layers. This is due to the extremely large number of degrees-of-freedom in neural networks, leaving their generalisation ability vulnerable to effects such as overfitting. However, there remain many domains where extensive data gathering is not always appropriate, affordable, or even feasible. Furthermore, data is generally organised in more complicated kinds of structure---which most existing approaches would simply discard. Examples of such tasks are abundant in the biomedical space; with e.g. small numbers of subjects available for any given clinical study, or relationships between proteins specified via interaction networks. I hypothesise that, if deep learning is to reach its full potential in such environments, we need to reconsider "hard-coded" approaches---integrating assumptions about inherent structure in the input data directly into our architectures and learning algorithms, through structural inductive biases. In this dissertation, I directly validate this hypothesis by developing three structure-infused neural network architectures (operating on sparse multimodal and graph-structured data), and a structure-informed learning algorithm for graph neural networks, demonstrating significant outperformance of conventional baseline models and algorithms.

Although agri-food products occupy an important position in the total trade structure of the Central and East European countries, their significance in the exchange of agri-food products in the Community is incomparably smaller.

description: The production of charmonia in ultrarelativistic heavy-ion collisions is investigated including two sources. These are a primordial contribution coupled with various phases of dissociation, and a statistical coalescence of $c$ and $\bar{c}$ quarks at the hadronization phase transition. Within a schematic fireball evolution, SPS data on $J/Ψ$ production can be reasonably well reproduced. Remaining discrepancies in the $Ψ'/Ψ$ ratio are discussed. Predictions for the $J/Ψ$ centrality dependence at RHIC energies are confronted with first data from PHENIX. The pertinent excitation function of the $N_{J/Ψ}/N_{c\bar{c}}$ ratio exhibits a characteristic minimum structure signaling the transition from the standard $J/Ψ$ suppression scenario (SPS) to predominantly statistical production (RHIC).

description: Development of intensive agriculture is a perspective direction in the world, but also in Moldavia. The natural factors, as well as knowledge and technology developed on this basis, ensuring a high yield, quality, competitiveness and specialization of production, will be both contributing to the development of agriculture as a branch, as well as the social efficiency of production. European integration and scientific progress offers new opportunities for raising agricultural output. The goal of the paper was to characterize perspectives of Moldavia’s agricultural sector following country’s potential accession to the European Union. As a conclusion we can say that the main factors in ensuring the competitiveness of agricultural products are quality, which manifests itself through price differentiation and diversity of sales channels.

description: Objectives. The research purpose of this article was to investigate the status of laboratory safety culture in universities, in order to carry out more targeted laboratory cultural construction activities in the later stage. Safety culture also can have a lasting impact on university students as future practitioners. Methods. With Southeast University as a case study, a sample of 8761 study participants completed the safety culture measurement questionnaire (SCMQ). The independent-sample t test, single-factor analysis of variance and multilevel logistic regression were used to analyze the general characteristic distribution of the safety culture level. Results. The overall average score of safety culture was 74.84. Among the 32 elements of safety culture, six elements scored less than 60 points. Multilevel logistic regression analysis showed that the distribution of safety culture scores varied across schools, work roles, genders, years of laboratory use and laboratory safety culture familiarity. Conclusions. University laboratories should strengthen the construction of safety culture, for the safety elements with low scores, and intervene from the organizational level (school level). The key focus groups were males, students and those who have used the laboratory for 2–4 years, and those with low awareness of safety culture.

description: Assessment of fish trophic ecology in natural environments is imperative to understand biological and ecological requirements, supporting the management and conservation of populations and environments. There are several methods available to assess fish diets, generically divided in noninvasive approaches, such as underwater observations, and invasive approaches, such as analyses of lipid biomarkers, stable isotopes and stomach contents. Each one has application assumptions and conditions that must be aligned with study objectives and methodological criteria, assuring results robustness and allowing comparability among different studies. This review addresses the advantages and limitations of these methods, highlighting those applied for stomach analysis (SA). This work presents complete updated review concerning qualitative and quantitative methods applied to SA: sixty equations were reviewed comprising four formulae to value stomachs per se and, for stomach content analysis, eight single indices, fifteen composite indices and thirty-three equations related to modeling approaches. The review presents different potentialities associated to these methods, standardizes distinct names applied to a same method, and provides clarifications on confusion sources due to the use of same names in distinct methods, a source of scientific mistakes detected in the specialized literature.
A multi-technique approach to characterise acidic surface properties of microporous catalysts

Year: 2018
Subjects: zeolites

description: Microporous catalysts belong to a class of materials that exhibit pore networks in the molecular dimension, that is, channel diameters less than 2 nm. The industrially most important microporous catalysts are zeolites, which are crystalline aluminosilicates and consist of interlinked alumina (AlO4) and silica (SiO4) tetrahedra forming pores and cavities of molecular dimensions. Zeolites can act as very strong solid acids and function as heterogeneous catalysts in various industrial processes used to obtain polyethylene terephthalate (PET) or polyvinyl chloride (PVC). They are crucial for products with a significant market demand such as plastics used in bottles, packaging materials and household consumable goods as well as for coatings of pharmaceutical pills and detergents. Recently, zeolites have been found to have increased applications in aqueous and biphasic reactions that use reactants derived from biomass to arrive at petrochemical products. Thus, surface acidity in zeolites is crucial to understand to tune parameters such as activity and selectivity of zeolite catalysts to optimize product distributions. The objective of this dissertation was to validate the use of non-invasive nuclear magnetic resonance (NMR) techniques to characterise surface acidity in zeolites by benchmarking the NMR results to various more established zeolite characterisation techniques, such as Fourier transform infrared (FTIR) spectroscopy and temperature-programmed desorption (TPD). Furthermore, the use of the tapered element oscillating microbalance (TEOM) to characterise internal and external acidity in zeolites was explored. IR and TPD techniques were used to assess important acidity parameters such as type, number, location and strength of acid sites of ZSM-5 zeolites with varying silica-alumina ratio (SAR = SiO2/Al2O3). The use of NMR relaxation time analysis of pyridine adsorbed in ZSM-5 was then explored as a model system to study surface acidity in microporous materials. Correlation with pyridine TPD results suggested that NMR relaxation time analysis probes the effective strength of pyridine adsorption sites, which varies with SAR. NMR relaxation time analysis was then further shown to be applicable to characterise non-acidic surface properties such as the hydrophilic and hydrophobic surface character. Lastly, the NMR techniques developed at high magnetic field strength (300 MHz) were transferred to a portable, low-cost benchtop low-field (43 MHz) magnet and shown to be applicable for base probe molecules other than pyridine, that is, ammonia (NH3) as well as zeolite framework types other than ZSM-5, that is, chabazite (CHA).

description: In 1963 a partial differential equation with a convolution non-linearity was introduced in connection with a quantum mechanical many-body problem, namely the gas of bosonic particles. This equation is mathematically interesting for several reasons. (1) Although the equation was expected to be valid only for small values of the parameters, further investigation showed that predictions based on the equation agree well over the {\it entire range} of parameters with what is expected to be true for the solution of the true many-body problem. (2) The novel nonlinearity is easy to state but seems to have almost no literature up to now. (3) The earlier work did not prove existence and uniqueness of a solution, which we provide here along with properties of the solution such as decay at infinity.

The Case Against Cold, Dark Chromospheres

description: Is the solar chromosphere always hot, with relatively small temperature variations ($δT/T\sim0.1$); or is it cold most of the time, with temperature fluctuations that reach $δT/T\sim 10$ at the top of the chromosphere? Or, equivalently: Is the chromosphere heated continually, or only for a few seconds once every three minutes? Two types of empirical model, one essentially time independent and always hot, the other highly time dependent and mostly cold, come to fundamentally different conclusions. This paper analyzes the time-dependent model of the quiet, nonmagnetic chromosphere by Carlsson & Stein (1994: CS94) and shows that it predicts deep absorption lines, none of which is observed; intensity fluctuations in the Lyman continuum that are much larger than observed; and time-averaged emission that falls far short of the observed emission. The paper concludes that the solar chromosphere, while time dependent, is never cold and dark. The same conclusion applies for stellar chromospheres. A complete, time-dependent model of the nonmagnetic chromosphere must describe two phenomena: (1) dynamics, like that modeled by CS94 for chromospheric bright points but corrected for the geometrical properties of shocks propagating in an upward-expanding channel; and (2) the energetically more important general, sustained heating of the chromosphere, as described by current time-independent empirical models, but modified in the upper photosphere for the formation of molecular absorption lines of CO in a dynamical medium. This model is always hot and, except for absorption features caused by departures from local thermodynamic equilibrium, shows chromospheric lines only in emission.

description: Learning continuous-time dynamics on complex networks is crucial for understanding, predicting and controlling complex systems in science and engineering. However, this task is very challenging due to the combinatorial complexities in the structures of high dimensional systems, their elusive continuous-time nonlinear dynamics, and their structural-dynamic dependencies. To address these challenges, we propose to combine Ordinary Differential Equation Systems (ODEs) and Graph Neural Networks (GNNs) to learn continuous-time dynamics on complex networks in a data-driven manner. We model differential equation systems by GNNs. Instead of mapping through a discrete number of neural layers in the forward process, we integrate GNN layers over continuous time numerically, leading to capturing continuous-time dynamics on graphs. Our model can be interpreted as a Continuous-time GNN model or a Graph Neural ODEs model. Our model can be utilized for continuous-time network dynamics prediction, structured sequence prediction (a regularly-sampled case), and node semi-supervised classification tasks (a one-snapshot case) in a unified framework. We validate our model by extensive experiments in the above three scenarios. The promising experimental results demonstrate our model's capability of jointly capturing the structure and dynamics of complex systems in a unified framework.

description: This paper examines the evolution of national agricultural sectors m European Commumty (EC) member countries over the last decade of general econom1c turbulence. It assesses the degree of between-country "convergence" in trends in sectoral variables achieved under the influence of the EC's common agricultural pohcy (CAP). Principal components analysis 1s used to identify similarities and differences. S1milanties were particularly noticeable between certain subgroups of countries. Despite considerable divergences m rates of 1nflatton, an overall tendency towards convergence emerges for internal tenns of trade and for real incomes considered as real value added per agricultural labour unit. The patterns of convergence emerging from this study show a certain parallel with those found in studies of convergence conducted at macro level. The result 1s considered as a positive achievement for the CAP, which appears to have inserted the agncultural sector mto the process of economic mtegration foreseen by the founders of the European Community.

description: The quantum null energy condition (QNEC) is a quantum generalization of the null energy condition which gives a lower bound on the null energy in terms of the second derivative of the von Neumann entropy or entanglement entropy of some region with respect to a null direction. The QNEC states that $\langle T_{kk}\rangle_{p}\geq lim_{A\rightarrow 0}\left(\frac{\hbar}{2πA}S_{out}^{\prime\prime}\right)$ where $S_{out}$ is the entanglement entropy restricted to one side of a codimension-2 surface $Σ$ which is deformed in the null direction about a neighborhood of point $p$ with area $A$. A proof of QNEC has been given before, which applies to free and super-renormalizable bosonic field theories, and to any points that lie on a stationary null surface. Using similar assumptions and methods, we prove the QNEC for fermionic field theories.

description: Rural poverty is the mam constituent of poverty worldWlde and 1s measurable in terms of undernutrihon, shorter life expectancy, and tlltteracy. Of ten southern African countnes, Lesotho, South Africa, and Swaziland have dietary energy supplies per ca put m excess of requirements, and the remaining countnes have food deficits. But average figures conceal mequality, and poverty and undernutrition are shown to be widespread m the less developed rural areas of Lesotho, South Afnca, and Swaziland (the three countries examined m detail m this paper), where few rural families produce marketable surpluses of food. Incomes m the three countries derive mainly from migrant earnings and remittances, land may be underutilized because off-farm earnings of men exceed the incomes that may be earned from their tribal land allotments, and the domestic demands on women restrict their capacity to be farmers. Inadequate access to land is a major constraint to development, along with the inhibitions of a tribal authority system, lack of infrastructure, inadequate education and extension, restrictions of labour flows to towns, and the high retail pnce of rural food.

description: If a Nakayama algebra is not cyclic, it has finite global dimension. For a cyclic Nakayama algebra, there are many characterizations of when it has finite global dimension. In [She17], Shen gave such a characterization using Ringel's resolution quiver. In [IZ92], the second author, with Zacharia, gave a cyclic homology characterization for when a monomial relation algebra has finite global dimension. We show directly that these criteria are equivalent for all Nakayama algebras. Our comparison result also reproves both characterizations. In a separate paper we discuss an interesting example that came up in our attempt to generalize this comparison result to arbitrary monomial relation algebras [HI19].

description: This study examines three alternative public policies to expand growth in Canadian agncultural production and trade: an approximately 50 percent increase in publicly-funded research and development, a 2 percent subsidy on exports for expanded market development, and a 25 percent reduct10n m the tariff equivalent of trade bamers. The study used a world food model developed at the International Institute for Applied Systems Analysis (IIASA) to evaluate the impacts of the alternatIVC policies during 1980-2000. The results showed that the largest gains from trade liberalization would be for livestock products, where protection IS currently highest Market development activities would also benefit livestock most, as demand is more responswe to market pnces. Productivity increases would be most effective in expanding grain production and exports.

description: Standard stellar evolution theory is inconsistent with the observed isotopic carbon ratio, 12C/13C, in evolved stars. This theory is also inconsistent with the 3He/H abundance ratios observed in Galactic HII regions, when combined with chemical evolution theory. These discrepancies have been attributed to an extra, non-standard mixing which further processes material during the RGB and should lower both the 12C/13C and 3He/H abundance ratios for stars with masses < 2 solar masses. Measurements of isotopic ratios in planetary nebulae probe material which escapes the star to be further processed by future generations of stars. We have measured the carbon isotopic abundance ratio, 12C/13C, in 11 planetary nebulae (PNe) by observing the J=2-->1 and J=3-->2 millimeter transitions of 12CO and 13CO in molecular clouds associated with the PNe. A large velocity gradient (LVG) model has been used to determine the physical conditions for each PNe where both transitions have been detected. We detect both 12CO and 13CO in 9 PNe. If 12CO/13CO = 12C/13C, the range of 12C/13C is 2.2--31. Our results support theories which include some form of extra mixing.

description: The effects of cost-sharing and technical assistance on nonindustrial private forest owners' investment in timber stand improvements are analyzed using a two-step estimation method. We use survey data on Finnish NIPF owners' stand improvements, including precommercial thinnings and cleaning of seedling stands as well as restoration thinnings of overstocked juvenile stands in 1994-1998. The investment decision is theoretically considered in a two-period consumption-savings model with amenity values. To allow for the joint determination of participation in the cost-sharing program and the decision to invest, a two-step estimation method is used. The predicted probability of using public subsidy from the first-step model is included in the second-step model explaining the probability or relative extent of stand improvements. For robust inference, a quasi-maximum likelihood estimation technique and the Murphy-Topel correction are applied. Both public subsidy, personal assistance and forest planning expectedly increased the probability to invest. Especially public subsidy had substantial effects on the probability as well as extent of stand improvement. Besides overcoming the endogeneity of cost-sharing, the two-step approach showed that personal assistance also encourages stand improvements indirectly through its effect on the use of public subsidy

description: We recapitulate the method which resums the truncated perturbation series of a physical observable in a way which takes into account the structure of the leading infrared renormalon. We apply the method to the Gross-Llewellyn Smith (GLS) sum rule. By confronting the obtained result with the experimentally extracted GLS value, we determine the value of the QCD coupling parameter which turns out to agree with the present world average.
