description: In this work we describe the development process and present the first flight results obtained for the I2T5, the first ever iodine-based propulsion system launched to space in November 2019. The system uses the sublimation ofsolid iodine to build up a gas pressure in the storage tank, which is then guided to the nozzle. The main challenge of using iodine as a propellant in a cold gaspropulsion system is the corrosive nature of the iodine, which is a halogen with moderate chemical activity towards most of the metals including stainless steel, as well as other common substances found in spacecrafts. The accelerationof flows in such system is also a complex task, since the maximum vapor pressure of the propellant is defined by the maximum allowed temperature of operation, chosen to avoid solid-to-liquid phase transition which would result in the need to use precise micro-nozzles. The other challenges,such as the possibility of fragmentation of the propellant with consequent loss of the thermal contact and “bouncing” in microgravity conditions, have also been studied and resolved. Here we present the main approaches to our development process and describe the key solutions which resulted in having a space-ready operational device.

Self-similar orbit-averaged Fokker-Planck equation for isotropic spherical dense clusters (iii) application of pre-collapse solution to Galactic globular clusters

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

description: This is the third paper of a series of our works on the self-similar orbit-averaged Fokker-Planck (OAFP) equation. The first paper provided an accurate spectral solution of the equation for isotropic pre-collapse star clusters and the second detailed the physical feature of the model. Based on the works, the present work applies the solution to the observed structural profiles of Galactic globular clusters. For fitting to the profiles, the most fundamental (quasi-)stationary model, the King model, and the variants have shown successful results while they can not apply to core-collapsing and core-collapsed clusters at the late stage of the relaxation evolution. We propose an energy-truncated self-similar OAFP model that can apply to clusters at both the early and late stages of the evolution. This new model fits the structural profiles of at least half of Galactic globular clusters while it also applies to core-collapsed stars with resolved cores. As a main result, we provide the completion rate of core collapse against concentration for the clusters. Also, we show our new model can apply to the globular clusters even in a broad range of radii (0.01$\sim$10 arcminutes). However, since our model includes polytrope (elongated outer halo), the tidal radius of the model becomes unrealistically large for some clusters. To avoid the issue, we also propose an approximated form of the new model. Lastly, we report that Milky Way globular clusters with low concentrations have the same spatial structures as stellar polytropes and discuss whether such polytropic cluster is a reasonable concept.

description: We study the problem of the electron excitation spectrum in the presence of point-like and regularized Coulomb impurities in gapped graphene. To this end, we use the Dirac model and in the point-like case theory of self-adjoint extensions of symmetric operators. In the point-like case, we construct a family of self-adjoint Hamiltonians describing the excitations for any charge of an impurity. Spectra and (generalized) eigenfunctions for all such Hamiltonians are found. Then, we consider the spectral problem in the case of a regularized Coulomb potential of impurities for a special regularization. We study exact equations for charges of impurities that may generate bound states with energy that coincides with the upper boundary of the negative branch of the continuous spectrum (supercritical charges) and calculate these charges.

description: Raloxifene hydrochloride (RH) suffers from low oral bioavailability due to its low water-solubility and first-pass metabolism. Therefore, a novel phospholipid complex of RH (RHPC) and a matrix dispersion based on phospholipid complex (RHPC-MD) were successfully prepared and optimized. Several methods were used to validate the formation of RHPC and RHPC-MD, such as differential scanning calorimetry, X-ray diffraction, scanning electron microscopy, transmission electron microscopy, infrared spectroscopy, particle size, and zeta potential, meanwhile, their octanol–water partition coefficient, solubility, and dissolution in vitro were also evaluated. To investigate the absorption mechanism of RHPC in vivo, the RHPC was administered to the chylomicron flow blockage rat model. Interestingly, as we expected, a significant reduction in RHPC absorption (67%) (**pin vivo. Pharmacokinetic studies revealed that the relative oral bioavailability of RHPC as well as RHPC-MD was 223% and 329%, respectively, when comparing with the commercial RH tablets. These outcomes suggested that the current study provided an attractive formulation to enhance the oral bioavailability of RH and stimulated to further research the absorption mechanism of RHPC in vivo.

description: Blockchain (BC) systems are highly distributed peer-to-peer networks that offer an alternative to centralized services and promise robustness to coordinated attacks. However, the resilience and overall security of a BC system rests heavily on the structural properties of its underlying peer-to-peer overlay. Despite their success, BC overlay networks' critical design aspects, connectivity properties and network-layer inter-dependencies are still poorly understood. In this work, we set out to fill this gap and study the most important overlay network structural properties and robustness to targeted attacks of seven distinct BC networks. In particular, we probe and crawl these BC networks every two hours to gather information about all their available peers, over a duration of 28 days. We analyze 335 network snapshots per BC network, for a total of 2345 snapshots. We construct, at frequent intervals, connectivity graphs for each BC network, consisting of all potential connections between peers. We analyze the structural graph properties of these networks and compare them across the seven BC networks. We also study how these properties associate with the resilience of each network to partitioning attacks, i.e., when peers are selected, attacked and taken offline, using different selection strategies driven by the aforementioned structural properties. In fact, we show that by targeting fewer than 10 highly-connected peers, major BCs such as Bitcoin can be partitioned into disjoint, i.e., disconnected, components. Finally, we uncover a hidden interconnection between different BC networks, where certain peers participate in more than one BC network, which has serious implications for the robustness of the overall BC network ecosystem.

description: We define a numerical scheme that allows to approximate a given Hamiltonian by an effective one, by requiring several constraints determined by exact properties of generic ''short range'' Hamiltonians. In this way the standard lattice fixed node is also improved as far as the variational energy is concerned. The effective Hamiltonian is defined in terms of a guiding function $ψ_G$ and can be solved exactly by Quantum Monte Carlo methods. We argue that, for reasonable $ψ_G$ and away from phase transitions, the long distance, low energy properties are rather independent on the chosen guiding function, thus allowing to remove the well known problem of standard variational Monte Carlo schemes based only on total energy minimizations, and therefore insensitive to long distance low energy properties.

description: Spectroscopic analysis of AC magnetic signal using diamond quantum magnetometry is a promising technique for inductive imaging. Conventional dynamic decoupling like XY8 provides a high sensitivity of an oscillating magnetic signal with intricate dependence on magnitude and phase, complicating high throughput detection of each parameter. In this study, a simple measurement scheme for independent and simultaneous detection of magnitude and phase is demonstrated by a sequential measurement protocol. Wide-field imaging experiment was performed for an oscillating magnetic field with approximately 100$μ$m-squared observation area. Single pixel phase precision was $2.1^\circ$ for 0.76$μ$T AC magnetic signal. Our method enables potential applications including inductive inspection and impedance imaging.

description: Krabi River Estuary, a ramsar site located in southern Thailand, is dominated by two major natural vegetation assemblages, i.e. mangrove forests and seagrass beds. According to the cluster development strategy, the cabinet has approved in principle to develop Krabi as the global marine tourism center and economic gateway of Asia. This study aimed to assess the economic value of the site, using market price and benefit transfer. The impact on economic activities with the 5% annual decline of mangrove forests was evaluated. The estimated annual use value of the site was $9.7 million for recreation and tourism. The economic value of mangrove forests was $758/ha. The net present value of mangrove forests was $73.1 million based on 7% discount rate and 15-year time line. An approximate impact of mangrove change follows the study of Ruitenbeek (1992). It was assumed that the impact on local direct resource extraction and loss in biodiversity would occur at the year after the depletion of the forest. The impact on the productivity of local fishery would occur in the fifth year and on tourism in the tenth year. Thus, value loss of mangrove at the annual rate of 5% in the net present term became $21.0 million or $2.3 million per year. The results imply that a development project that causes the same rate of mangrove destruction must generate a least an income of $2.3 million per year to be considered as an economically feasible project.

description: The seed industry in Thailand is among the advanced and well-developed industries in Asia. Maize contributes to the largest share of seed production and trade. The government and international organizations contributed significantly to the success of the maize seed industry in Thailand by building infrastructure for research and promoting the role of the private sector in the industry during the early years. The private sector also added to the industry’s rapid expansion through constant and heavy investment in research and development. Thailand’s goal of becoming a seed hub center in this region is bolstered by its suitable geography and weather, numerous highly trained plant scientists, wide diversity of germplasm, and membership in the Association of Southeast Asian Nations (ASEAN) Economic Community (AEC), which will come into effect at the end of 2015. Despite promising motivations, domestic regulations could be prohibitive factors in Thailand’s becoming competitive in the regional seed market. This paper provides the history of development; an analysis of the current industry’s structure, conduct, and performance; and a review of related regulations of the maize seed industry in Thailand. The lessons learned from the success of the maize seed industry in Thailand could provide implications for the development of the seed industry in other developing countries.

description: Non reciprocal spin waves have a chiral asymmetry so that their energy is different for two opposite wave vectors. They are found in atomically thin ferromagnetic overlayers with in plane magnetization and are linked to the anti-symmetric Dzyaloshinskii-Moriya surface exchange. We use an itinerant fermion theory based on first principles calculations to predict that non-reciprocal magnons can occur in Fe$_3$GeTe$_2$, the first stand alone metallic two dimensional crystal with off-plane magnetization. We find that both the energy and lifetime of magnons are non-reciprocal and we predict that acoustic magnons can have lifetimes up to hundreds of picoseconds, orders of magnitude larger than in other conducting magnets.

description: Indian rose-ringed parakeet (Psittacula krameri) is one of the most recognizable illegally trafficked wild birds. With feral populations in Europe and Australia, its phylogeny and taxonomy are of great interest amongst biologists. The information regarding the genetic composition and make up of Psittacula species from various geographic regions is scarce and incomplete. This study aimed to generate the first partial mitogenome sequence of the species from India. We generated 2611 base pair long mitochondrial sequence of P. krameri. The overall base composition was calculated at AT (52.59%) and GC (47.41%). The complete NAD1 protein-coding gene was annotated along with partial NAD2 protein-coding gene. The sequence encoded four tRNA genes (Isoleucine, Leucine, Glutamine, and Methionine) as well as partial sequence of 16 s rRNA. Psittacula krameri demonstrated closer phylogenetic relation with P. eupatria than P. derbiana. We also reported that Psittacula species have closest phylogenetic relationship with E. roratus than any other parrots.

description: Over the past 20 years, flood and drought in Thailand have impacted up to 2.58 million farming households and caused damages about 6,000 million Baht each year. Various studies have examined natural hazard impacts on the Thai economy and particularly on agricultural sector. Moving towards sustainable development, economic vulnerability to natural hazards should be improved which could be linked to disaster mitigation policies and development. This study aims to explore the Kuznets relationship between economic growth and damages from flood and drought in the Thai agricultural sector using annual data at the provincial levels during 1989-2012. It is hypothesized that as the country becomes wealthier, appropriate development and investment in disaster mitigation could lead to disaster reduction in agricultural sector. Results from the random effect regression support the Kuznets hypothesis in the models for both flood and drought. Precipitation variation increases agricultural damages due to flood and drought significantly. Agricultural damages reduce with rising provincial incomes, increased flood retention area and increased areas for perennial crops.

description: Using the spectroscopic sample of the SDSS DR1 we measure how gas was transformed into stars as a function of time and stellar mass: the baryonic conversion tree (BCT). There is a clear correlation between early star formation activity and present-day stellar mass: the more massive galaxies have formed about 80% of their stars at $z>1$, while for the less massive ones the value is only about 20%. By comparing the BCT to the dark matter merger tree, we find indications that star formation efficiency at $z>1$ had to be about a factor of two higher than today ($\sim 10%$) in galaxies with present-day stellar mass larger than $2 \times 10^{11}M_\odot$, if this early star formation occurred in the main progenitor. Therefore, the LCDM paradigm can accommodate a large number of red objects. On the other hand, in galaxies with present-day stellar mass less than $10^{11}$ M$_{\odot}$, efficient star formation seems to have been triggered at $z \sim 0.2$. We show that there is a characteristic mass (M$_* \sim 10^{10}$ M$_{\odot}$) for feedback efficiency (or lack of star formation). For galaxies with masses lower than this, feedback (or star formation suppression) is very efficient while for higher masses it is not. The BCT, determined here for the first time, should be an important observable with which to confront theoretical

description: In recent years, automated, supervised classification techniques have been fruitfully applied to labeling and organizing large astronomical databases. These methods require off-line classifier training, based on labeled examples from each of the (known) object classes. In practice, only a small batch of labeled examples, hand-labeled by a human expert, may be available for training. Moreover, there may be no labeled examples for some classes present in the data, i.e. the database may contain several unknown classes. Unknown classes may be present due to 1) uncertainty in or lack of knowledge of the measurement process, 2) an inability to adequately ``survey'' a massive database to assess its content (classes), and/or 3) an incomplete scientific hypothesis. In recent work, new class discovery in mixed labeled/unlabeled data was formally posed, with a proposed solution based on mixture models. In this work we investigate this approach, propose a competing technique suitable for class discovery in neural networks, and evaluate both methods for classification and class discovery on several astronomical data sets. Our results demonstrate up to a 57% reduction in classification error compared to a standard neural network classifier that uses only labeled data.

description: Today Thailand is the second largest field crop seed exporter in Asia with maize contributing the highest value to seed exports. Hybrid maize is considerably adopted in Thailand mainly due to the demand from feed industry and development of livestock and poultry industry. The success of varietal development of commercial maize hybrids is owed to the investments of international donors during the 1980s and continuous breeding efforts of multinational seed companies even as public institutions played a key role in maintaining genetic resources conservation and pre-commercial lines research. This paper reviews the history of research and development in maize and maize seed market development in Thailand. Furthermore, expert elicitation method is used to reveal the adoption of commercial maize varieties in 2013/2014 cropping seasons. The results of adopted maize varieties were used to estimate market shares and suggested that maize seed market in Thailand is moderately concentrated with tendencies towards oligopolistic competition.

description: Large-scale shape-changing interfaces have great potential, but creating such systems requires substantial time, cost, space, and efforts, which hinders the research community to explore interactions beyond the scale of human hands. We introduce modular inflatable actuators as building blocks for prototyping room-scale shape-changing interfaces. Each actuator can change its height from 15cm to 150cm, actuated and controlled by air pressure. Each unit is low-cost (8 USD), lightweight (10 kg), compact (15 cm), and robust, making it well-suited for prototyping room-scale shape transformations. Moreover, our modular and reconfigurable design allows researchers and designers to quickly construct different geometries and to explore various applications. This paper contributes to the design and implementation of highly extendable inflatable actuators, and demonstrates a range of scenarios that can leverage this modular building block.

description: Members of departments of Agricultural Economics are rightly concerned as to how their graduates perform as they accept diverse responsibilities in a multitude of careers. This concern about employers; opinions of out students has undoubtedly precipitates numerous, perhaps continuous review of departmental course offerings and requirements, consuming significant energies of both educators and employers. To neglect this effort would leave a department--our profession-- in the stagnant waters of nonrelevancy.
title: An Assessment of the Political and Legal Career of Robert Price
Creators: name: Evans, Evan David
Publisher: name: The Open University
Year: 1998

description: After qualifying as a barrister, Robert Price entered the service of the Council in the Marches at Ludlow where he came to the notice of the Duke of Beaufort. The Duke placed him as his agent in extending royal control in several borderland municipalities and gained admission for him into Court circles under James II. His career was blighted by the Revolution and, expecting few favours from William III, Price concentrated on his parliamentary activities. Reared in the Tory tradition of loyalism, he now had to adjust with the party to a role in opposition in becoming the 'Country party'. He was active in support of 'Country' men and measures under Robert Harley’s leadership whom he supported both in his own locality and in Parliament. He was gratified by Harley’s overtures to the Tories which he promoted and which emanated in the 'New Country Party'. Though always a diligent parliamentarian. Price only came into prominence when he led a campaign against the grant by William III of two Denbighshire lordships to the Earl of Portland which culminated in a memorable speech in the House of Commons. Price skilfully elevated a local grievance into an issue of national significance which enabled him to launch an attack on King William’s policies on all fronts and was effective in stopping the grant. Price emerged as the foremost spokesman for Wales in Parliament at a crucial time in its history following the abolition of the Council in the Marches which had governed it for a century and half. To make the necessary adjustments, William III's parliaments had to undertake an unprecedented amount of legislation relating to Wales not seen since Henry VIII’s time and Robert Price’s legal knowledge and expertise was drawn upon for the purpose. He subscribed to the 'old constitutional school' of Toryism which he helped to shape and which was to characterise Welsh Toryism for a century in its vigilance against the growth of executive power.
The Relevance of Agricultural Economics to Industry

description: Concern about the relevance of work carried on by agricultural economists probably began three-quarters of a century ago with the appointment of Henry C. Taylor as the first professor of agricultural economics in a land grant institution. The dialogue has continued with changing emphasis during periods of depression; war years, overproduction, and structural changes that have occurred in the production sector resulting from the historic migration of farm workers to urban centers and out of agricultural employment. Castle in. 1970 warned that flexibility in organizational structure of research and extension activities would be necessary if programs were to have great relevance to fast-changing and non-static problems.
Quasi-classical DBAR-dressing approach to the weakly dispersive KP hierarchy

Subjects: subject: Exactly Solvable and Integrable Systems (nlin.SI)

description: Recently proposed quasi-classical DBAR-dressing method provides a systematic approach to study the weakly dispersive limit of integrable systems. We apply the quasi-classical DBAR-dressing method to describe dispersive corrections of any order. We show how calculate the DBAR problems at any order for a rather general class of integrable systems, presenting explicit results for the KP hierarchy case. We demonstrate the stability of the method at each order. We construct an infinite set of commuting flows at first order which allow a description analogous to the zero order (purely dispersionless) case, highlighting a Whitham type structure. Obstacles for the construction of the higher order dispersive corrections are also discussed.

description: Growth of entrepreneurial ventures plays important role in a country’s economic development and entrepreneurs’ growth intention is considered as an important predictor of their venture growth. On the other hand, Psychological capital (PsyCap) is one such resource which can influence attitudes and behaviours like growth intentions of entrepreneurs. This study is aimed to investigate the relationship between psychological capital and growth intentions of entrepreneurs specifically in Malaysian context. The data was collected from 275 Malaysian SME entrepreneurs and Regression analysis reveals that PsyCap, as a core construct, positively and significantly influences the growth intentions of entrepreneurs. Further, it is also identified that two out of four dimensions of PsyCap (hope and self-efficacy) have significant and positive influence on entrepreneurs’ growth intentions. It is also revealed that PsyCap, as a core construct, more powerfully predicts the growth intentions as compared to its first order constructs separately. This finding highlights the significance of PsyCap as a core construct in entrepreneurial researches. It contributes knowledge to psychological capital and entrepreneurship literature and also has implications for existing and prospective entrepreneurs as well as government and private bodies.

description: There is growing emphasis on the role of institutions on explaining Africa’s economic growth ahead of the traditional factors such as capital accumulation. However, it is not clear which of the institutions and governance indicators namely control of corruption, government effectiveness, political stability, regulatory quality, rule of law and voice and accountability matter most. This paper empirically examines the impact of institutions on economic growth in Africa. The paper uses a sample of 48 countries for the1996-2016 period. The overall number of observations is 912. The paper applied generalized methods of moment (GMM), fixed effects (FE) and random effects (RE) models. However, due to the fact that GMM is well suited to deal with potential endogeneity problems in the model, inferential statistics of this paper are drawn from GMM regression results. Results of the FE and RE regressions are presented in appendix. Empirical results show that institutions really matter for Africa’s economic growth. Among the institutional quality indicators political stability appears to be the most significant factor in explaining real GDP per capita growth in Africa. However, it is worth noting that, the quality of institutions alone may not be sufficient. Along with institutions, the paper reveals that structural factors such as liberalization of trade, fixed capital formation, labour force and foreign direct investment have a significant effect on Africa’s economic growth. The implication is that, a policy mix with the aim of improving the quality of institutions as well as reducing trade restrictions, enhancing both domestic and foreign investment and improving the quality of labour force would enhance economic growth in Africa.

description: The exact computation of asymptotic quasinormal frequencies is a technical problem which involves the analytic continuation of a Schrodinger-like equation to the complex plane and then performing a method of monodromy matching at the several poles in the plane. While this method was successfully used in asymptotically flat spacetime, as applied to both the Schwarzschild and Reissner-Nordstrom solutions, its extension to non-asymptotically flat spacetimes has not been achieved yet. In this work it is shown how to extend the method to this case, with the explicit analysis of Schwarzschild de Sitter and large Schwarzschild Anti-de Sitter black holes, both in four dimensions. We obtain, for the first time, analytic expressions for the asymptotic quasinormal frequencies of these black hole spacetimes, and our results match previous numerical calculations with great accuracy. We also list some results concerning the general classification of asymptotic quasinormal frequencies in d-dimensional spacetimes.

description: We describe the inclusion of electrodynamic fields in Time-Dependent Density Functional Theory (TDDFT) by incorporating both the induced scalar and vector potentials within the time-dependent Kohn-Sham equation. The Hamiltonian is described in both the Coulomb and Lorenz gauges, and the advantages of the latter are outlined. Integral expressions are defined for the retarded potentials of each gauge and a methodological approach to evaluate these nontrivial expressions with low computational cost is adopted. Various molecular structures of relatively small sizes are studied, including water, benzene, and conductive carbon chains. Absorption cross sections resulting from both pulse and boost excitations suggest a preserved gauge-invariance of the proposed formal approach to TDDFT in the weak magnetic field limit.
