Direction of Japan's Agricultural Policy Responding to the Recent World Food Situation

description: Due to a smaller number of exporting countries and a larger number of importing countries in international food trade caused by continuous tariff reduction under the WTO (World Trade Organization) system, the recent grain prices are more responsive to changes in supply-demand balance. Moreover, the sense of insecurity becomes a cause of export restraint and raging grain speculation, thereby increasing grain price volatility. Food importing countries recognized after the recent world food crisis that each country should maintain a certain level of basic food production in its own country. However, since the current WTO rules have several unfair aspects favorable to exporting countries with large-scale farms, it would be difficult for Asian small-scale rice farming to survive under these rules. The rules focus on economic efficiency without considering external economies such as national security and environmental concerns. Furthermore, it is said that a total ban on export subsidies by the end of 2013 was agreed, but the pledge is very unlikely to be fulfilled because many “hidden” export subsidies are left out of this agreement. Therefore, Asian countries should aim jointly to incorporate more comprehensive rules for sustainable growth of Asian agriculture into the worldwide rules. In order to re-vitalize rice farming in Japan, we should allow producers' discretion in cropping and introduce inductively coordinated direct (deficiency) payments to rice by end use (direct consumption, rice powder, animal feed, and biofuel) and alternative crops (wheat and soybeans), based on calculated differences between a standard (or target) production cost and a standard selling price. In addition, direct payments based on agricultural multi-functionality should be expanded especially for small farmers in mountainous areas.

Benign vs malicious ghosts in higher-derivative theories

description: Interacting theories with higher derivatives involve ghosts. They correspond to instabilities that display themselves at the classical level. We notice that comparatively "benign" mechanical higher-derivative systems exist where the classical vacuum is stable with respect to small perturbations and the problems appear only at the nonperturbative level. We argue that benign higher-derivative field theories exist which are stable with respect to small fluctuations with nonzero momenta. A particular example is the 6D N=2 higher-derivative SYM theory, which is finite and unitary at the perturbative level. The inflation-like instability with respect to small fluctuations of static modes is always present, however.

Subjects: Agricultural and Food Policy

description: Since the 1980s staple food consumption has fallen and feed consumption and industrial consumption have increased in the China corn market. Till 2007 staple food consumption has fallen to 10% and feed consumption has increased to 65% of total corn consumption, and the rest of corn consumption went to industrial use. In the changing process of corn supply and demand structure, the demand for corn as industrial material was the strongest. During the past 30 years China witnessed the fastest growth in the corn supply, which was due to progress in agricultural technology and expansion of corn growing area. In the future, the increase in the corn supply will mainly depend on progress in agricultural technology and upgrading of medium and low yield land. Owing to the food security policy of the Chinese government, China's corn export is characterized by fluctuation. Though China highly values self-sufficiency in grain, the export of corn should not be halted. The rational policy for China is to import corn in south area and to export corn in northeast area.

Ziel ist es, ein Besucher_innenzentrum mit Forschungsund Übernachtungsmöglichkeiten zu errichten, das sich einerseits in die Umgebung einbindet und sie andererseits akzentuiert. Um dies zu erreichen wurde das architektonische Motiv des Weges gewählt. Bei Güi-Güi handelt es sich um ein Gebiet, das nur zu Fuß oder per Schiff erreicht werden kann. Am Barranco de Güi-Güi kommt es zu einer Weggabelung. Die beiden abzweigenden Wege werden durch den Baukörper geschlossen, sodass ein Rundweg entsteht. Das Gebäude selbst besteht aus vier Strängen, die sich fortwährend miteinander und mit der Umgebung verflechten. Durch diese Fächerungen bilden sich entsprechende Terrassen aus. Die einzelnen Ebenen kommen am verlassenen Bauplatz der ehemaligen Tomatenverpackungsanlage zusammen und bilden dort das Auditorium aus mit Blick in die benachbarte Bucht und in die Weite.
description: This diploma thesis explores the Güi-Güi territory, which is located in the West of Gran Canaria. The goal is to erect a visitor centre that while not only allowing for overnight stays but also providing research facilities, integrates which as well as accentuates its environment. In order to achieve this, the architectural motive of the pathway was chosen: Güi-Güi can only be reached by foot or by boat, and, at the Barranco de Güi-Güi , the Pathway forks. The two pathways are connected and, thereby “closed” by the structure, so that they form a loop. The structure itself comprises four strands, which continuously intertwine witch each other as well as with the environment. As a consequence thereof, the structure forms terraces. The individual levels meet at the abandoned construction site of a tomato packing plant where they combine into an auditorium with a view over the bay.

description: Nowadays, computer-based simulation is an important tool to study various phenomena in cardiac biology ranging from investigating the properties of single ion channels to predict the onset of cardiac arrhythmia. Due to the complexity of calculations, these simulations are generally computationally expensive and resource intensive. In the last decade, there has been a great effort to accelerate computer-based cardiac simulation by implementing efficient parallel algorithms that leverage multi-cores CPU and many-cores GPUs currently available also in common personal computers. These algorithms are generally developed using imperative languages dictating the control flow of the program. In this work I am investigating the use of hardware-based accelerators provided by Maxeler Dataflow Technology to improve the simulation time of the electrical activity of a homogenous 1D cell cable and an isolated single cell. This technology relies on dataflow paradigm, in which the data processing elements, called pipelines, operate concurrently and are connected in a way that the output of one element is the input for the following/next one. In my work I am additionally comparing the advantages and disadvantages of the proposed approach with the current state-of-the-art based on CPU and GPU regarding performance and resource utilization.

As a result, we deduce evolution equations for conformal maps that admit quasiconformal extensions and, in particular, such that the associated quasidisks are bounded by smooth Jordan curves. Some applications to Hele-Shaw flows of viscous fluids are given.

description: Up to now, the methods available for measuring the rate constants of reactions taking place on heterogeneous catalysts require that the catalyst be stable over long measurement times. But catalyst are often non-stationary, they may become activated under reaction conditions or become poisoned through use. It is therefore desirable to develop methods with high data acquisition rates for kinetics, so that transient rates can be measured on non-stationary catalysts. In this work, we present velocity resolved kinetics using high repetition rate pulsed laser ionization and high-speed ion imaging detection. The reaction is initiated by molecular beam pulses incident at the surface and the product formation rate is observed by a sequence of laser pulses at a high repetition rate. Ion imaging provides the desorbing product flux (reaction rate) as a function of reaction time for each laser pulse. We demonstrate the method using a 10 Hz pulsed CO molecular beam pulse train to initiate CO desorption from Pd(332) - desorbing CO is detected every millisecond by non-resonant multiphoton ionization using a 1-kHz Ti:Sapphire laser. This approach overcomes the time-consuming scanning of the delay between CO and laser pulses needed in past experiments and delivers a data acquisition rate that is 10-1000 times higher. We also apply this method to CO oxidation on Pd(332) - we record kinetic traces of CO$_2$ formation while a CO beam titrates oxygen atoms from an O-saturated surface. This provides the reaction rate as a function of O-coverage in a single experiment. We exploit this to produce controlled yet inhomogeneously mixed reactant samples for measurements of reaction rates under diffusion-controlled conditions.

description: Yang--Mills theories in four space-time dimensions possess a hidden symmetry which does not exhibit itself as a symmetry of classical Lagrangians but is only revealed on the quantum level. It turns out that the effective Yang--Mills dynamics in several important limits is described by completely integrable systems that prove to be related to the celebrated Heisenberg spin chain and its generalizations. In this review we explain the general phenomenon of complete integrability and its realization in several different situations. As a prime example, we consider in some detail the scale dependence of composite (Wilson) operators in QCD and super-Yang--Mills (SYM) theories. High-energy (Regge) behavior of scattering amplitudes in QCD is also discussed and provides one with another realization of the same phenomenon that differs, however, from the first example in essential details. As the third example, we address the low-energy effective action in a N=2 SYM theory which, contrary to the previous two cases, corresponds to a classical integrable model. Finally, we include a short overview of recent attempts to use gauge/string duality in order to relate integrability of Yang--Mills dynamics with the hidden symmetry of a string theory on a curved background.

description: We present HST and FUSE observations of the intergalactic absorption toward PG1116+215 in the 900-3000 A spectral region. We detect 25 Ly-alpha absorbers at rest-frame equivalent widths W_r > 30 mA, yielding (dN/dz)_Ly-alpha = 154+/-18 over an unblocked redshift path of 0.162. Two additional weak Ly-alpha absorbers with W_r ~ 15-20 mA are also present. Eight of the Ly-alpha absorbers have large line widths (b > 40 km/sec). The detection of narrow OVI in the broad Ly-alpha absorber at z=0.06244 supports the idea that the Ly-alpha profile is thermally broadened in gas with T > 10^5 K. We find dN/dz ~ 50 for broad Ly-alpha absorbers with W_r > 30 mA and b > 40 km/sec. If the broad Ly-alpha lines are dominated by thermal broadening in hot gas, the amount of baryonic material in these absorbers is enormous, perhaps as much as half the baryonic mass in the low-redshift universe. We detect OVI absorption in several of the Ly-alpha clouds along the sight line. Two detections at z=0.13847 and z=0.16548 are confirmed by the presence of other ions at these redshifts, while the detections at z=0.04125, 0.05895, 0.05928, and 0.06244 are based upon the Ly-alpha and OVI detections alone. The information available for 13 low-redshift OVI absorbers with W_r > 50 mA along 5 sight lines yields (dN/dz)_OVI ~ 14 and Omega_b(OVI) > 0.0027/h_75, assuming a metallicity of 0.1 solar and an OVI ionization fraction < 0.2. The properties and prevalence of low-redshift OVI absorbers suggest that they too may be a substantial baryon repository, perhaps containing as much mass as stars and gas inside galaxies. The redshifts of the OVI absorbers are highly correlated with the redshifts of galaxies along the sight line, though few of the absorbers lie closer than 600/h_75 kpc to any single galaxy.

Tradition and Challenge of Historical Study on Albrecht Daniel Thaer and Johann Heinrich von Thünen

Subjects: Farm Management

description: The important contribution to agricultural science by A.D. Thaer and J.H.v. Thünen is not a question that needs to be argued. This paper aims not only to survey the historical studies of these classics using quite new information after the reunion of the two Germanies, but also to discuss the current interpretations in view of sustainable agriculture by these classical models as a blueprint of the future. The author could find some aspects of analytical tools from these models to construct a methodology of agroecology, that is to say, an optimization of ecology and economy in agriculture. It would be also possible to develop the theory of agroecology on the basis of these classical studies.
How to realize a negative refractive index material at the atomic level in an optical frequency range

description: The theoretical mechanism for realizing the negative refractive index with {\it electromagnetically induced transparency} (EIT) is studied. It is shown that in a three-level dense atomic gas, there is a frequency band in which the EIT medium will exhibit simultaneously negative electric permittivity and magnetic permeability in the optical frequency range, and the atomic gas thus becomes a left-handed material. The expressions for the electric permittivity and the magnetic permeability for the probe frequency is presented. One of the remarkable features of the present novel scheme is such that the obtained EIT left-handed material is {\it isotropic} and may therefore have some potentially important applications in the development of new techniques in quantum optics.

description: We study the shadow behaviors of five dimensional (5D) black holes embedded in type IIB superstring/supergravity inspired spacetimes by considering solutions with and without rotations. Geometrical properties as shapes and sizes are analyzed in terms of the D3-brane number and the rotation parameter. Concretely, we find that the shapes are indeed significantly distorted by such physical parameters and the size of the shadows decreases with the brane or "color" number and the rotation. Then, we investigate geometrical observables and energy emission rate aspects.
Giant magnetocaloric effect driven by first-order magneto-structural transition in cosubstituted Ni-Mn-Sb Heusler compounds: predictions from \textit{Ab initio} and Monte Carlo calculations

description: Using Density Functional Theory and a thermodynamic model [Physical Review B 86, 134418 (2012)], in this paper, we provide an approach to systematically screen compounds of a given Heusler family to predict ones that can yield giant magnetocaloric effect driven by a first-order magneto-structural transition. We apply this approach to two Heusler series Ni$_{2-x}$Fe$_{x}$Mn$_{1+z-y}$Cu$_{y}$Sb$_{1-z}$ and Ni$_{2-x}$Co$_{x}$Mn$_{1+z-y}$Cu$_{y}$Sb$_{1-z}$, obtained by cosubstitution at Ni and Mn sites. We predict four new compounds with potentials to achieve the target properties. Our computations of the thermodynamic parameters, relevant for magnetocaloric applications, show that the improvement in the parameters in the predicted cosubstituted compounds can be as large as four times in comparison to the off-stoichiometric Ni-Mn-Sb and a compound derived by single substitution at the Ni site, where magnetocaloric effects have been observed experimentally. This work establishes a protocol to select new compounds that can exhibit large magnetocaloric effects and demonstrate cosubstitution as a route for more flexible tuneability to achieve outcomes, better than the existing ones.

description: It is noted that if large Nc continuum reduction applies to an observable, then that observable is independent of temperature for all temperatures below some critical value. This fact, plus the fact that mesons and glueballs are weakly interacting at large Nc is used as the basis for a derivation of large Nc continuum reduction for the chiral condensate. The structure of this derivation is quite general and can be extended to a wide class of observables.
Studies on enzymes of sialic acid and pseudaminic acid biosynthesis
Creators: name: Chou, Wayne Kuo Wei
Publisher: name: University of British Columbia
Year: 2010

description: The first two steps in the mammalian biosynthesis of sialic acid are catalyzed by a bifunctional hydrolyzing UDP-GlcNAc 2-epimerase/ManNAc kinase. The hydrolyzing epimerase domain, which catalyzes the conversion of UDP-GlcNAc to ManNAc and UDP, was studied mechanistically. Incubation of UDP-GlcNAc in deuterated buffer produced α-[2-²H]ManNAc indicating that the epimerase reaction proceeds with a net retention of configuration at C-1 and that C-2 is deprotonated and reprotonated with a solvent-derived deuterium atom. The enzymatic incubation of a potential reaction intermediate, 2-acetamidoglucal, resulted in a slow hydration reaction, forming ManNAc. A positional isotope exchange and kinetic isotope effect experiment demonstrated that UDP loss occurs through a C-O bond cleavage and that C-2 deprotonation is not rate-limiting. These results support a mechanism involving the anti-elimination of UDP, forming 2-acetamidoglucal, followed by its syn-hydration, forming ManNAc. SiaA, a monofunctional hydrolyzing UDP-GlcNAc 2-epimerase from Neisseria meningitidis, was recently identified to catalyze a mechanistically similar reaction to the mammalian epimerase and its study was undertaken to identify catalytic residues. Mutagenesis produced three SiaA mutants, D100N, E122Q and D131N. In each case catalysis was severely impaired, however, products were detected upon extended incubations. E122Q and D131N catalyzed the release of 2-acetamidoglucal before the formation of ManNAc, demonstrating that hydrolyzing epimerases are able to catalyze the direct formation of 2-acetamidoglucal. Pseudaminic acid synthase is proposed to catalyze the condensation of PEP and 6-deoxy AltdiNAc to form pseudaminic acid and phosphate. The activity of a pseudaminic acid synthase has never before been observed, but a gene candidate, (neuB3 from Campylobacter jejuni NCTC 11168) potentially encoding a protein fulfilling this role, was identified and cloned. The activity of NeuB3 was studied through the synthesis and enzymatic incubation of its potential substrate, 6-deoxy AltdiNAc. NMR spectroscopic analysis verified the activity of NeuB3 as a pseudaminic acid synthase and that the absolute stereochemistry of the pseudaminic acid produced had the L-glycero-L-manno configuration. Kinetic analysis revealed that NeuB3 requires a divalent metal ion for catalysis and that optimal catalysis occurs at pH 7.0. Incubation with [2-¹⁸O]PEP demonstrated that NeuB3 operates via a C-O bond cleavage mechanism utilized in PEP-condensing synthases studied to date.

description: This paper measures the gross stock of capital of cultivators and tractors in Japanese agriculture during the period from 1975 to 2000, with special focus on the quality changes. The physical stock value method is applied, taking the quality difference of the stock produced in various years into account. First, the physical stock is broken down by the year produced. Second, the quality adjustment index is calculated for each year. Third, the quality-adjusted physical stock is calculated by using the broken-down physical stock and the quality adjustment index. Last, the gross stock of capital is calculated as the product of the price and the quality-adjusted physical stock. This paper also estimates the gross capital formation and the durable period. Conventional gross capital stock and gross capital formation, which leave quality changes out of consideration, are also measured. The results of measurement show that the gross capital stock of cultivators and tractors in Japanese agriculture with quality changes has grown more rapidly than that of conventional estimation.
A general non-adiabatic quantum instanton approximation

description: We present a general quantum instanton approach to calculating reaction rates for systems with two electronic states and arbitrary values of the electronic coupling. This new approach, which we call the non-adiabatic quantum instanton (NAQI) approximation, reduces to Wolynes theory in the golden rule limit and to a recently proposed projected quantum instanton (PQI) method in the adiabatic limit. As in both of these earlier theories, the NAQI approach is based on making a saddle point approximation to the time integral of a reactive flux autocorrelation function, although with a generalised definition of the projection operator onto the product states. We illustrate the accuracy of the approach by comparison with exact rates for one dimensional scattering problems and discuss its applicability to more complex reactions.

The Use of Nonlinear Tariffs for Irrigation Water in Agricultural Drainage Control

description: If agricultural drainage from an area imposes costs on society through damaging the environment, and if the measurement of the drainage discharged from each plot in the area is too costly, then it may be necessary to control the drainage by regulating the irrigation tariffs levied on agricultural producers operating there. The purpose of this paper is to analyze how, in such a situation, the regulator of the irrigation tariffs can control drainage and enhance social welfare by using increasing block tariffs for irrigation water. This paper first explains irrigation technology choices by producers and the social costs of their water application when a linear tariff or two-tier increasing block tariff is used to charge for irrigation water. It then examines how variations in the tail block rate of the increasing block tariff affect social welfare, changing agricultural production decisions. When a two-tier increasing block tariff is used to price irrigation water, there can be land areas where producers apply larger volumes of water using traditional irrigation technology. In such a case, it is possible that rises in the tail block rate of the increasing block tariff induce the producers in the area i) to employ modern irrigation technology instead of traditional irrigation technology, or ii) to reduce water application while continuing to use traditional irrigation technology. This paper clarifies what conditions are sufficient for these effects of rises in the tail block rate to contribute to the enhancement of social welfare. The paper also deduces sufficient conditions for the existence of an increasing block tariff for irrigation water that yields a level of social welfare higher than a given linear irrigation tariff. A numerical simulation is conducted to illustrate how two-tier increasing block tariffs can raise social welfare with the above effects.

In this paper we approach the question of aberrations, both through the evaluation of the wavefront evolution along the system and its departure from the ideal spherical shape and the use of ray density plots. Using seventh-order matrix modeling, we can calculate the optical path between any two points of a ray as it travels along the optical system and we define the wavefront as the locus of the points with any given optical path; the results are presented on the form of traces of the wavefront on the tangential plane, although the formalism would also permit sagital plane plots. Ray density plots are obtained by actual derivation of the seventh-order polynomials.

Risk and Uncertainty

description: The objective of this paper is to investigate the fact that an increase in risk exposure gives negative effects on the expansion of the calf-raising farm size by using a dynamic econometric model. It is empirically known that the calf-raising farms facing the risk of calf price fluctuation tend to reduce the number of beef cows to escape a shrink in their future profitability; however, most previous studies on beef production have not discussed how uncertainty concerning prices affects the investment behavior of risk-averse producers because of their intending to analyze the mechanism of beef cycle. The main findings from the empirical results of this study imply that a ratio of risk premium to the expected calf price is 17.2% during the period calf price goes down drastically. The ratio of 17.2% is greater than the ones which are estimated in the previous studies as the case of the rice and dairy farms. In addition, a result of the decomposition analysis of the investment behavior indicates that uncertainty concerning prices induces risk averse farmers to reduce the farm size in the observation period; therefore，the variance of calf prices has significant effects on the farm size expansion as well as the expected value of calf prices.
Organosilane adsorption on light metal alloys

description: This thesis discusses research on the adhesive bonding of organosilanes to alloys of Al and Mg using surface analysis techniques (especially secondary-ion mass spectrometry (SIMS), X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy (SEM)). One project involved comparing the adsorption of bis-1,2-(triethoxysilyl)ethane (BTSE) on high-purity Al, and on anodized 7075-Al alloy, for different pre-treatments involving chemical and heating procedures, and exposure to a H₂ plasma. The objectives were to assess the effects of these pre-treatments on the direct Al-O-Si covalent bonding and the strength of the adhesive coating. The separate adsorption of BTSE and γ-glycidoxypropyltrimethoxysilane (γ-GPS) on an air-oxidized mirror-polished 7075-Al surface was studied with an emphasis on the different microstructural regions of the alloy surface with scanning Auger microscopy (SAM). BTSE at its natural pH (4.3) adsorbed on the Al-Cu-Mg and Al-Fe-Zn types of second-phase particles, and on the alloy matrix, while γ-GPS adsorbed on all these regions only after the starting pH was reduced from its natural value (5.7) to 3.2. However, with prior heating of the sample (200°C, 15 min), γ-GPS adsorption occurred on all regions even at pH 5.7. Time-of-flight (TOF)-SIMS was used for the first time to indicate the nature of the metal-O-Si bonding at the different micro-regions. The Mg-based alloy AZ91 was characterized with regard to its different surface micro-regions both from mirror-polished and fractured surfaces, as well as oxide growth and oxide stability on heating. There is a clear tendency for Mg oxidation, which covers the Al component, while other elements (Zn and Mn) are detected only with bulk characterization methods, although localized Mn-rich particles (dimensions ~3 μm) are identified by SEM and energy-dispersive X-ray (EDX) spectroscopy. In a coating environment (by 1% solutions of BTSE, γ-GPS, γ-APS at their natural pH values) the Mg oxide is etched, and adsorption occurs on the different regions of the alloy, but the attachment is weak, especially because of the fragile nature of the underlying substrate. However 4% BTSE (at pH 3.9) formed a thicker and denser coating with better prospects for substrate protection.

description: The leapfrogging motion of smoke rings is a three dimensional version of the motion that in two dimensions leads to exotic exchange statistics. The statistical phase factor can be computed using the hydrodynamical Euler equation, which is a universal law for describing the properties of a large class of fluids. This suggests that three dimensional exotic exchange statistics is a common property of closed vortex loops in a variety of quantum liquids and gases, from helium superfluids to Bose-Einstein condensed alkali gases, metallic hydrogen in its liquid phases and maybe even nuclear matter in extreme conditions.

description: One of the most complex manifestations of Shiva is his Nataraja form. As Nataraja, the king of dance, he projects the elements of ugra and saumya aspects, besides the auspicious and inauspicious cosmic aspects of life. His dance is for the creation and destruction. Thus, the form exhibits a duality or two extremes of reality. The trend of making the image of Nataraja originally began in northern India and later got popularised in southern regions of India, especially during the time of Chola rulers in Tamil Nadu. Medieval temples of Kerala possess a good number of representations of Nataraja Shiva. Ernakulam Shiva temple has an excellent sculptural exposition of Nataraja Shiva in wood.

description: The megalithic culture is the major field of research in Kerala and the Megalithic archaeology of the state is still in the beginning stage in spite of the number of works carried out in the state in 19th and 20th centuries. Scholars were mainly interested in certain aspects of the Megalithic archaeology of particular regions. As a result, majority of the places in Kerala haven’t received much attention. Thiruvananthapuram district is one such area where very less systematic researches were conducted till date. Various agencies like Archaeological survey of India, State Archaeology Department and various universities conducted sporadic explorations and excavations in different parts of Thiruvananthapuram. But a systematic exploration of Thiruvananthapuram is a very important task. Without extensive explorations and systematic study of the burials, a real account of the Megalithic culture of Thiruvananthapuram could not be developed. It was therefore a preliminary survey conducted in Nellanad village of Nedumagadu taluk to understand the present scenario of megalithic monuments in Thiruvananthapuram district and the explorations yielded 8 new megalithic sites.

description: A Content Delivery Network (CDN) is a dynamic and complex service system. It causes a huge amount of traffic on the network infrastructure of Internet Service Providers (ISPs). Oftentimes, CDN providers and ISPs struggle to find an efficient and appropriate way to cooperate for mutual benefits. This challenge is key to push the quality of service (QoS) for the end-user. We model, simulate, and optimize the behavior of a CDN to provide cooperative solutions and to improve the QoS. Therefor, we determine reasonable server locations, balance the amount of servers and improve the user assignments to the servers. These aspects influence run time effects like caching at the server, response time and network load at specific links. Especially, user request history and profiles are considered to improve the overall performance. Since we consider multiple objectives, we aim to provide a diverse set of pareto optimal solutions using simulation based optimization.

description: We show how to double-copy Heavy Quark Effective Theory (HQET) to Heavy Black Hole Effective Theory (HBET) for spin $s\leq 1$. In particular, the double copy of spin-$s$ HQET with scalar QCD produces spin-$s$ HBET, while the double copy of spin-1/2 HQET with itself gives spin-1 HBET. Finally, we present novel all-order-in-mass Lagrangians for spin-1 heavy particles.

description: Pneumonia is the leading cause of death among young children and one of the top mortality causes worldwide. The pneumonia detection is usually performed through examine of chest X-ray radiograph by highly-trained specialists. This process is tedious and often leads to a disagreement between radiologists. Computer-aided diagnosis systems showed the potential for improving diagnostic accuracy. In this work, we develop the computational approach for pneumonia regions detection based on single-shot detectors, squeeze-and-excitation deep convolution neural networks, augmentations and multi-task learning. The proposed approach was evaluated in the context of the Radiological Society of North America Pneumonia Detection Challenge, achieving one of the best results in the challenge.

description: The purpose of this paper is to analyse the relationship between the market structure of the corn exporting industry in the U.S. and the price transmission from corn cash prices at the export ports in the U.S. Gulf to CIF prices at the import ports in Japan. Based on the arguments of Asymmetric Price Transmission (APT), the market share of the U.S. grain exporting companies is investigated in order to illustrate the market structure, and the price transmission is estimated by applying the Threshold Autoregressive (TAR）Model and M (Momentum)-TAR Model. The main conclusions are as follows. The market concentration was relatively small in the 1980s and the first half of 1990s due to restructuring and consolidation of grain exporting companies. In the last half of 1990s and the 2000s, however, the market became less competitive and the market concentration got larger. The inference results using TAR and M-TAR models show that corn prices were transmitted more rapidly when the input-output price differences were squeezed than when they were stretched, which is so called positive APT, in the sample of the last half of 1990s and the 2000s, although the corn prices were transmitted symmetrically in the sample of the 1980s and the first half of 1990s. The Error Correction Model (ECM), in which the results of inferences by using TAR and M-TAR models were incorporated, was applied to find which factors have impacts on CIF import price changes. It was revealed that the Gulf cash prices mainly 3 months ago and the ocean freight rates 2-3 months ago most significantly affected the changes in CIF prices.
