description: Recent advances in quantum technology have led to the development and the manufacturing of programmable quantum annealers that promise to solve certain combinatorial optimization problems faster than their classical counterparts. Semi-supervised learning is a machine learning technique that makes use of both labeled and unlabeled data for training, which enables a good classifier with only a small amount of labeled data. In this paper, we propose and theoretically analyze a graph-based semi-supervised learning method with the aid of the quantum annealing technique, which efficiently utilize the quantum resources while maintaining a good accuracy. We illustrate two classification examples, suggesting the feasibility of this method even with a small portion (20%) of labeled data is involved.

description: We present optical and near-infrared observations of the afterglow of the gamma-ray burst GRB 050904. We derive a photometric redshift z = 6.3, estimated from the presence of the Lyman break falling between the I and J filters. This is by far the most distant GRB known to date. Its isotropic-equivalent energy is 3.4x10^53 erg in the rest-frame 110-1100 keV energy band. Despite the high redshift, both the prompt and the afterglow emission are not peculiar with respect to other GRBs. We find a break in the J-band light curve at t_b = 2.6 +- 1.0 d (observer frame). If we assume this is the jet break, we derive a beaming-corrected energy E_gamma = (4-12)x10^51 erg. This limit shows that GRB 050904 is consistent with the Amati and Ghirlanda relations. This detection is consistent with the expected number of GRBs at z > 6 and shows that GRBs are a powerful tool to study the star formation history up to very high redshift.

title: Understanding Social Influence Differently: A Discursive Study of Livery Yards
Creators: name: Smart, Cordet Anne
Publisher: name: The Open University
Year: 2014

description: The present thesis offers a synthetic, discursive psychological investigation into social influence, as manifested in an everyday context - a livery yard in the south-west of England. Drawing on insights from Conversation Analysis, Discursive Psychology and Critical Discursive Psychology, the thesis demonstrates the limitations of traditional social psychological approaches to social influence, especially in terms of our understanding of how influence manifests itself in everyday life. The thesis argues that in order to understand social influence in practice it is important to study language in action, that is, the discursive and interactional practices through which influence is produced and through which people orient towards the possibility of influence. Also, the thesis examines how influence is mediated by other social actions including the demonstration of competence, exercise of leadership or the production of identity. The research presented in the thesis is based on the analysis of over 200 hours of audio and video data collected over eleven months of ethnographic work in a livery yard. The livery yard was chosen as the appropriate setting because social influence, in terms of giving, accepting or resisting advice, is a frequent concern both for the owners and the users of the livery yard. Also, the nature of the interactions in a livery yard, and the complexity of the social relationships between the management, staff and the customers meant that different forms of advice giving and orientations to influence could be readily observed, recorded and analysed. By examining how social influence is produced, oriented to and resisted in an everyday context, and by promoting a synthetic discursive approach to this quintessential social psychological topic, the thesis offers a timely critique of traditional research into social influence and contributes to the broader project of re-specifying social psychology in discursive, social constructionist terms.

description: The high level of competition between food products on the market has encouraged the development of various types of functional foods. Consumer demands and requirements for both medicinal and healthy products has caused food manufacturers to widen their product offerings. The objective of this study was to present the legal status of functional food production and sales, as well as analyse the possibilities of developing customized foods, in particular, highly satiating foods. In this time of obesity epidemic, the use of specifically designed food products which suppress hunger and give the feeling of satiety could be an effective tool in preventing obesity and controlling body mass. There is an optimistic prognoses that this type of food will be introduced on the Polish market.

description: Distribution of organic food in Poland has a number of weaknesses resulting from low and irregular supply as well as dispersion of producers and intermediaries. The paper presents the outcomes of research carried out in 2012 in three types of retail outlets offering organic food, i.e. specialist shops, groceries and retail networks. The investigation was conducted in the form of indepth interviews using a standardised questionnaire. As the research shows, only in specialist stores does the product range satisfy consumer needs, whereas in the other outlets it is limited generally to processed products. Wholesalers, organic farms and brokers are the main providers of the surveyed retail outlets; nevertheless, specialist shops use the services of more providers than the other types of outlets. Low supply of organic food results in high retail prices. Specialist shops and groceries apply margins up to 40% on average, while retail networks have margins up to 20%.

description: A spatial differentiation of the level of demographical senility was illustrated in the study, along with determination of dynamics of the European Union Member States ageing process (EU 27). The research period included years 1996-2016. The measures of demographical senility were used in the static and dynamical aspect. Country grouping due to the level of demographical senility advancement was performed based on statistical measures. A significant differentiation of the demographical senility level and population ageing process in the spatial system were found. The highest degree of demographical senility advancement was observed in the countries of “the old” Union but the greatest dynamics of this process was shown in the case of new Member States, including Poland and Baltic States.

description: Agriculture and the food system are responsible for one third of carbon dioxide emissions worldwide (Meleca, 2008). However, climate change public education initiatives rarely focus on food choice as a solution to reducing human impact on climate (Neff, Chan, & Clegg, 2008). Our project aims to increase consumers’ awareness of the impact of the food supply chain and personal food choices on climate change. We designed a carbon-friendly food guide with six key recommendations for reducing food-related carbon emissions. The brochure targets Vancouver residents and will be distributed at UBC's farmer's market. We have also created a website which complements the brochure and further elaborates on our recommendations, and a label to indicate which foods at the farmer's market are carbon-friendly. With the brochure, website and label, it is hoped that consumers at the UBC farm will become more conscious of the food system's contribution to climate change. Recognizing that greenhouse gas contributes to global warming and changing personal food choices can significantly decrease food system emissions.

description: Role of chemoprophylaxis for prevention of antitubercular therapy-related drug-induced liver injury (ATT-DILI) is uncertain. Electronic databases were searched for randomized trials reporting on chemoprophylaxis agents for prevention of ATT-DILI. We included studies evaluating the role of a drug in comparison to controls/placebo. The primary outcome was the occurrence of ATT-DILI. We performed a Bayesian random-effects network meta-analysis to calculate odds ratios (ORs) and 95% credible intervals (CrI) for those arms where at least two studies were available. Additional comparative studies for these arms were also identified. Fourteen studies were identified and seven included in the meta-analysis. The agents used for prevention of ATT-DILI were silymarin/silibinin (4 trials), N-acetylcysteine (NAC) (3 studies), herbal preparations (5 studies) and one study each for cholecalciferol and carnitine. Compared with controls/placebo, the odds of occurrence of hepatotoxicity with NAC was 7 * 10−17 (95% CrI: 2.8 * 10−53, 0.0053) and Silymarin was 0.68 (95% CrI: 0.084, 4.6). NAC had the highest probability of rank 1 (0.99) which was followed by Silymarin (0.004). N-acetyl cysteine, but not Silymarin/Silibinin, appears to be beneficial in prevention of ATT-DILI. However, the results were limited by the possible risk of bias in included studies, variable definitions of ATT-DILI and limited number and category of patients.

A theoretical investigation of the Humphreys-Davidson limit at high and low metallicity

description: Current massive star evolution grids are not able to simultaneously reproduce the empirical upper luminosity limit of red supergiants, the Humphrey-Davidson (HD) limit at high and low metallicity. In this study, we provide a better understanding of what drives massive star evolution to blue and red supergiant phases, with the ultimate aim of reproducing the HD limit at varied metallicities (Z). For solar, LMC, and SMC Z, we develop eight grids of MESA models for the mass range 20-60M to probe the effect of semiconvection and overshooting. We compare rotating and non-rotating models with efficient (alpha_semi = 100) and inefficient semi-convection (alpha_semi = 0.1), with high and low core overshooting (alpha_ov of 0.1 or 0.5). The red and blue supergiant evolutionary phases are investigated by comparing the fraction of core He-burning lifetimes spent in each phase. We find that the extension of the convective core by overshooting alpha_ov = 0.5 has an effect on the post-MS evolution which can disable semiconvection leading to more RSGs, but a lack of BSGs. We therefore implement alpha_ov = 0.1 which switches on semiconvective mixing, though for standard alpha_semi = 1, would result in an HD limit which is higher than observed at low Z. Therefore, we need to implement very efficient semiconvection of alpha_semi = 100 which reproduces the HD limit at log L ~ 5.5 for the Magellanic Clouds while simultaneously reproducing the Galactic HD limit of log L ~ 5.8 naturally. The effect of semiconvection is not active at high Z due to the depletion of the envelope structure by strong mass loss such that semiconvective regions could not form. Z-dependent mass loss plays an indirect, yet decisive role in setting the HD limit as a function of Z. For a combination of efficient semiconvection and low overshooting with standard Z-dependent mass loss, we find a natural HD limit at all metallicities.

description: Objectives: This study investigated the impact of polymer excipients on a typical cocrystal for sacubitril (SAC) and valsartan (VAL), aiming to guide optional formulation design and maximize oral bioavailability. Methods: Poly vinyl pyrrolidone (PVP) and hydroxypropyl cellulose (HPC) and hydroxypropyl methylcellulose (HPMC) were selected. The dissolution/permeation system was used to predict both the kinetics of drug supersaturation and the simple permeation. The intermolecular interaction was analyzed by 1H NMR spectroscopy and molecular dynamics simulation. Pharmacokinetic study was performed to assess the impact of polymer excipients in vivo. Results: Our study found that unappreciated excipients in the formulation, especially some polymers, might compete with the intermolecular hydrogen bonding among the cocrystals components and provide unexpected affinity, and thus leverage the therapeutic benefits. HPMC as a coating excipient used in the Entresto® tablet hampered the supersaturation of API, which led to the poor oral absorption of cocrystals. Conversely, PVP appeared to promote and maintain drug supersaturation, resulting in improved bioavailability of API. Conclusion: In conclusion, understanding the interplay between the cocrystal components and polymers is the key to optimizing the excipients to maximize the performance of cocrystal based oral drug formulation.

description: The article attempts to compare the importance of agriculture and the dynamics of its development in Ukraine and Poland. The most important constraints on the development of Ukrainian agriculture were identified, including the unregulated land market, lack of coherent support programs for agriculture and rural areas, poorly developed infrastructure of the agricultural environment and lack of capital for development. It was found that agriculture in Ukraine is characterized by a high growth rate of productivity and production. The observed output gap in relation to agriculture in Poland is about 10 years. The agricultural sector in Ukraine has about 10% share in generating GDP and as much as 40% share in exports. Such high importance can be maintained even in the conditions of economic development, as there are large reserves in the development of agribusiness. The most important development factors include the introduction of a coherent program for the development of the agribusiness sector, including production of goods with high added value and increasing the availability of capital for the development of agriculture. A great opportunity is the development of trade in the conditions of affiliation with the EU.

description: There are the producers who takes the weakest position on the agricultural market. Their activity is especially exposed to the risk factors. Price volatility which stays behind the price risk is one of the most important threats for producers’ incomes. Economic stability is a base for investment and development. That is why the price volatility is worth to having a look at. There are two species examined in this paper: onion and carrot. Both have a significant share in Polish vegetable production. Onion crops are mostly exported but carrot is being sold on the domestic market. Apart from the sales market there was no significant difference in analyzed period between farm-gate price volatility for both species. The measured volatility was getting lower in consecutive years of analyzed period; only in years of unfavorable weather conditions there were some growth. The analyze was conducted with usage of descriptive statistic on the logarithmic rates of return.

description: We report on spiking dynamics of frequency up-converted emission at 420 nm generated on the 6P3/2-5S1/2 transition in Rb vapour two-photon excited to the 5D5/2 level with laser light at 780 and 776 nm. The spike duration is less than the natural lifetime of any excited level involved in the interaction with both continuous and pulsed pump radiation. The spikes at 420 nm are attributed to temporal properties of the directional emission at 5.23 μm generated on the population inverted 5D5/2-6P3/2 transition. A link between the spiking regime and cooperative effects is discussed. We suggest that the observed stochastic behaviour is due to the quantum-mechanical nature of the cooperative effects rather than random fluctuation of the applied laser fields.

description: We show a generic finiteness result for least area planes in 3-dimensional hyperbolic space. Moreover, we prove that the space of minimal immersions of disk into hyperbolic space is a submanifold of a product bundle over a space of immersions of circle into sphere at infinity. The bundle projection map when restricted to this submanifold is Fredholm of index zero. By using this result, we also show that the space of minimal planes with smooth boundary curve at infinity is a manifold.

title: Performance Modelling, and Adaptive Control for Linked Sequential Systems
Creators: name: Morley, Paul Nicholas
Publisher: name: The Open University
Year: 2013

description: This thesis investigates the dynamics of linked sequential systems of machines in industrial laundries. Two aspects are considered: firstly the control of such systems and in particular the decision making point when a batch to be processed can be sent to one of many identical machines, and secondly the modelling of the whole system of linked machines. The decision making point in the control of these systems is frequently implemented in a sub-optimal manner, or a manner which becomes sub-optimal as conditions change. An adaptive system is preferable and an Evolutionary Artificial Neural Network approach (EANN) is proposed. The EANN is tested on simulations of real laundry systems and shown to be effective. Then it is applied to two abstract game playing problems in order to better understand its limitations. Limitations are found to include the fact that if learning does not appear to take place, it is not possible to determine if this is a failure of the Evolutionary approach or the Artificial Neural Network parameters. The dynamics and performance of Linked Sequential Systems in Industrial Laundries are not well understood or covered by theory in the literature. The theory of the performance of these systems is outlined, and an Agent Based Model (ABM) simulation presented. The ABM simulation is explained and then the simulation is compared to a real world system in an existing laundry. The performance of the existing system is measured and compared to the prediction of the ABM simulation. The ABM simulation is shown to offer a better understanding of the system than the previous static calculation. Finally the ABM is used in a design exercise to show how it could be used to specify a system more accurately than the static calculation at design stage.
Enhanced topological protection in planar quasi-one-dimensional channels with periodically-modulated width

description: We study one dimensional (1D) and quasi-1D periodic structures as possible platforms for the emergence of Majorana bound states with enhanced robustness against disorder and system inhomogeneity. First, using a simple 1D model, we analytically derive the effective parameters characterizing the minibands generated by the periodic potential. We show that, for strong enough periodic potentials, the higher energy minibands hosting Majorana bound states have significant advantages compared to their counterparts in uniform systems, including increased topological gaps, enhanced robustness against disorder, and enlarged parameter space regions consistent with the presence of topological superconductivity. We identify the problem of engineering a strong enough periodic potential as a key roadblock to realizing efficient periodic 1D structures. To address this challenge, we propose an efficient implementation of the periodic potential based on quasi-1D channels realized in 2D semiconductor heterostructures proximity coupled to superconductor strips of periodically modulated width. Our numerical study of the modulated channel device shows excellent agreement with the simple 1D model, reveals a topological phase diagram that is quite insensitive to the details of the confining potential associated with screening by the superconductor, and demonstrates that engineering patterned 2D structures represents a powerful and versatile approach to realizing robust Majorana bound states.

description: Potable water distribution systems are a dynamic environment requiring constant monitoring of the levels of contaminants, such as trihalomethanes (THMs) and haloacetic acids (HAAs), to ensure a high quality and that the regulatory standards are always met. The monitoring of specific disinfection by-products (DBPs) is not typically continuous as the current industrial practice is manual sample collection, at regular intervals and at known locations, which are then sent to specialist analytical laboratories for analysis. The aims of this project were to develop, optimise and apply new and existing analytical protocols for the analysis of THMs and HAAs from UK water sources. The project also provided an opportunity to evaluate if the methods were suitable for the analysis of THMs in near-real time (HS-GC-MS and HS-SPME-GC-MS). The early monitoring of THMs would allow any corrective measures to be implemented sooner. The suitability of GC-MS (El), GC-MS (ECNI), GCxGC-ToFMS and GC-μECD for HAA concentration measurements was also evaluated. Analysis of HAAs by GCxGC-ToFMS in treated water samples have not been reported before. Apart from the GC-MS (El), the analytical performance of the methods developed were generally equivalent to those used in regulatory laboratories. HS-GC-MS was then utilised to determine the influence of a series of parameters on the formation potential of THMs in upland and lowland water samples. Similarly, GC-μECD and GCxGC-ToFMS were utilised to determine the formation potential of HAAs. GC-μECD was also applied to the determination of HAA concentrations in treated water samples from geographically different sources in the UK. The total HAAs concentration across thirteen sites in England had concentrations well below the US regulated levels of 60 μg/l.

Theoretical Aspects of Gamma-Ray Bursts

description: Cosmological GRBs are discussed with an emphasis on their plausible connection with black holes. GRBs can be triggered by collapse of stellar-mass objects that leads to formation of a black hole and a transient debris disk with a huge accretion rate. The disk is believed to produce a relativistic jet (``fireball'') that expands and emits to infinity the observed burst of gamma-rays. This accretion-jet picture is similar to quasars and X-ray binaries, however, there are important differences: the physical conditions and the cooling mechanism in the disk are very different. The observed radiation is emitted when the expanding fireball becomes transparent, at distances much larger than the Schwarzschild radius. The burst is then observed as a powerful relativistic explosion and the transient accretion disk in its center serves as a brief source of energy that drives the explosion. The explosion picture depends on the fireball nuclear composition which is shaped close to the black hole. A large amount of free neutrons survive till the emission phase and link the physics of the central engine to observed radiation.

description: This study examines the impact of remittances inflows on inter-sectoral migration of farm labor toward the non-agricultural sector. Using a panel of 77 developing countries over the period 1991–2010, we find two opposing effects of remittances on out-farm migration of labor. First, remittances slow down the out-farm migration rates by supplementing farm income and consumption expenditures. Second, remittances provide a source of investment in out-farm activities that increase the rate of migration out of agriculture over time. Combining these effects, our estimates indicate that a 100 percent increase in remittances reduces the migration out of agriculture by 10 percent over time. A major policy issue facing leaders in the developing world is whether international migration, through remittances, contributes to the development process in migrant-sending communities or impedes the efficient allocation of labor and human capital at origin countries. Our results indicate that international migrant remittances help slow the rate of out-farm labor migration through its supplemental income effect; remittances help finance farm households’ consumption expenditures, thereby eliminating the need to move to non-agricultural jobs.

description: This work discuss the construction of braneworld solutions in modified gravity with Lagrange multipliers. We examine the general aspects of the model and present a first order formalism that help us to find analytic solutions of the equations of motion. We also investigate some explicit models, analyse linear stability of the metric and comment on how to relate models investigated in other works to the ones examined in the present study.

description: Fluconazole-sensitive (CaS) and -resistant (CaR) C. albicans were grown as single-species and dual-species biofilms with Lactobacillus casei (Lc) and Lactobacillus rhamnosus (Lr). Single-species Lc and Lr were also evaluated. Biofilm analysis included viable plate counts, the extracellular matrix components, biomass, and structural organization. Lc reduced the viability of CaS, water-soluble polysaccharides, and eDNA in CaS + Lc biofilm. Lc biofilm presented more eDNA than CaS. The total biomass of CaS + Lc biofilm was higher than the single-species biofilms. The viability of Lc and Lr was reduced by CaR dual-species biofilms. The total and insoluble biomass in CaS + Lr was higher than in single-species CaS biofilms. Lc hindered the growth of CaS, and their association hampered matrix components linked to the structural integrity of the biofilm. These findings allow understanding of how the implementation of probiotics influences the growth of C. albicans biofilms and thereby helps with the development of novel approaches to control these biofilms.

description: First, we propose a scale-invariant modified gravity interacting with a neutral scalar "inflaton" and a Higgs-like SU(2)xU(1) iso-doublet scalar field based on the formalism of non-Riemannian (metric-independent) spacetime volume-elements. This model describes in the physical Einstein frame a quintessential inflationary scenario driven by the "inflaton" together with gravity-inflaton assisted dynamical spontaneous SU(2)xU(1) symmetry breaking in the post-inflationary universe, whereas SU(2)xU(1) symmetry remains intact in the inflationary epoch. Next, we find the explicit representation of the latter quintessential inflationary model with a dynamical Higgs effect as an Eddington-type purely affine gravity.

Interference of atomic levels and superfluid -- Mott insulator phase transition in a two-component Bose-Einstein condensate

description: The superfluid -- Mott insulator phase transition in a Bose-Einstein condensate of neutral atoms with doubly degenerate internal ground states in an optical lattice is theoretically investigated. The optical lattice is created by two counterpropagating linearly polarized laser beams with the angle $θ$ between the polarization vectors (lin-angle-lin configuration). The phase diagram of the system and the critical values of the parameters are worked out. It is shown that the sign of the detuning plays an important role and that there is a strong suppression of the Mott transition in the case of blue detuning. Varying the laser intensity and/or the angle $θ$ one can manipulate the Mott-insulator to superfluid quantum phase transition as well as prepare the condensate in physically distinguishable "ferromagnetic" and "antiferromagnetic" superfluid states.
GaiaNIR, our next astrometric mission (in the IR)

description: The All-Sky Visible and Near Infrared Space Astrometry GaiaNIR mission, built on Gaia principles, began his official journey on 2019 with the publication of the first white book. Two years later, on 2021, the ESA Science Programme Voyage 2050 selected the global astrometry in the near Infrared (NIR) as a key theme. The roadmap for the future μas astrometry in Europe is on the way! Peering through the dust, with a wavelength cutoff in the K-band, GaiaNIR will observe at least 5 times as many stars as Gaia. Furthermore, combined with Gaia and other space missions (e.g. Euclid and Jasmine) it will give a baseline of 25-35 years thus improving proper motions in a factor of 14-20 better that Gaia. With this potential accuracy, the dynamical evolution of the Milky Way will be traced looking at the inner bulge and bar and, at the same time, using traces out to 100 kpc with a potential accuracy of 2-3 km/s. Finally, GaiaNIR proper motions will also allow the study of massivelocal group galaxies. These are only examples of the extremely broad potential science cases of GaiaNIR, a mission that, as Gaia, will cover nearly every brach of astronomy.
