description: The Korea livestock industry is currently facing the critical challenge of the market liberalization trend under the World Trade Organization. This study analyzes the consumption behavior of meat and fish products in Korea, by estimating the Linear Approximate/Almost Ideal Demand System(LA/AIDS) for Korean meat and fish products. The empirical results indicate that beef imports in Korea would increase in the future under trade liberalization. If cheap and better quality imported beef is introduced to Korean consumers, Hanwoo beef would not be able to maintain its market share.

description: We develop an effective numerical method of studying large-time properties of reversible reaction-diffusion systems of type A + B C with initially separated reactants. Using it we find that there are three types of asymptotic reaction zones. In particular we show that the reaction rate can be locally negative and concentrations of species A and B can be nonmonotonic functions of the space coordinate x, locally significantly exceeding their initial values.

description: The so-called Lounesto's classification engenders six distinct classes of spinors, divided into two sectors: one composed by regular spinors (single-helicity spinors) and the other composed by singular spinors (comprising dual-helicity spinors). In the present essay we develop a mechanism to fully define the right class within the Lounesto's classification a spinor belongs to, without necessity to evaluate the 16 bilinear forms. The analysis lies in the following criteria: a judicious inspection of the phases factor present in both spinor's components. Thus, the machinery developed here works for both regular and singular spinors. Taking advantage of the present algorithm, we analyse, under certain conditions, the possibility to transmute between the six classes.

On the Rotation of Post-T Tauri Stars in Associations

Year: 2004
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Nearby associations are excellent objects for the study of the initial spin up phase during the PMS evolution. An empirical approach is adopted here to infer their rotations properties and relations to X-ray emission. Three nearby associations are considered. The TW Hya association with an age of 8 Myr, the Beta Pictoris moving group with 12 Myr and a combination of Tucana and Horologium associations (30 Myr). Two low and high rotation modes are considered for each association with stellar masses less than 1.5M and greater than 1.5M respectively. We infer representative equatorial rotation velocities Vo from the observed distribution of projected rotational velocities vsini. A spin up is found for the high rotation mode, whereas in the low rotation mode the Vo do not increase significantly. This insufficient increase of Vo is probably the cause of a decrease of the total mean specific angular momentum for the low mass stars between 8 and 30 Myr. However, for the high mass stars, where a sufficient spin up is present, the specific angular momentum is practically conserved in this same time interval. By supposing that the distribution of masses of these three associations follows a universal mass function, we estimate the number of members of these associations that remain to be detected. The analysis of rotation and stellar masses using luminosity X-rays indicators present similar properties, as the dependence on stellar mass and rotation, at least for the younger associations, to those obtained for T Tauri stars in the ONC. A strong desaturation effect appears at 30 Myr. This effect seems to be provoked by the minimum configuration of the stellar convection layers, attained for the first time for the higher mass stars at 30 Myr. The desaturation appears to be independent of rotation at this stage.

Unsourced Multiuser Sparse Regression Codes achieve the Symmetric MAC Capacity

Year: 2020

description: Unsourced random-access (U-RA) is a type of grant-free random access with a virtually unlimited number of users, of which only a certain number $K_a$ are active on the same time slot. Users employ exactly the same codebook, and the task of the receiver is to decode the list of transmitted messages. Recently a concatenated coding construction for U-RA on the AWGN channel was presented, in which a sparse regression code (SPARC) is used as an inner code to create an effective outer OR-channel. Then an outer code is used to resolve the multiple-access interference in the OR-MAC. In this work we show that this concatenated construction can achieve a vanishing per-user error probability in the limit of large blocklength and a large number of active users at sum-rates up to the symmetric Shannon capacity, i.e. as long as $K_aR < 0.5\log_2(1+K_a\SNR)$. This extends previous point-to-point optimality results about SPARCs to the unsourced multiuser scenario. Additionally, we calculate the algorithmic threshold, that is a bound on the sum-rate up to which the inner decoding can be done reliably with the low-complexity AMP algorithm.

description: The skin is a complex organ both structurally and functionally. Knowledge of the anatomy / histology of the skin and the external factors that affect its quality promotes a better understanding of skin changes related to its quality. In addition, it helps to achieve an optimal cosmetic and functional result during surgeries and non-surgeries aimed at maintaining the best possible skin quality. In the present work, the quantitative research was conducted using a questionnaire on the google forms website. A sample of the research consisted of a total of 100 citizens from different regions of Greece. The analysis of the results showed that the Greeks are aware of the dangers that their skin is exposed to by external factors. However, although they try to adopt a healthy diet, they do not systematically follow any method of protection. It is necessary to design and implement effective information programmes, based on the needs of citizens and with adequate and continuous organizational support.

description: Robust estimation of location for data on the unit sphere Sp−1 is an important problem in directional statistics even though the influence functions of the sample mean direction and other location estimators are bounded. A significant limitation of previous literature on this topic is that robust estimators and procedures have been developed under the assumption that the underlying population is rotationally symmetric. This assumption often does not hold with real data and in these cases there is a needless loss of efficiency in the estimator. In this paper we propose two estimators for spherical data, both of which are analogous to the affine-equivariant spatial median in Euclidean space. The influence functions of the new location estimators are obtained under a new semiparametric elliptical symmetry model on the sphere and are shown to be standardized bias robust in the highly concentrated case; the influence function of the companion scatter matrix is also obtained. An iterative algorithm that computes both estimators is described. Asymptotic results, including consistency and asymptotic normality, are also derived for the location estimators that result from applying a fixed number of steps in this algorithm. Numerical studies demonstrate that both location estimators may be expected to perform well in practice in terms of efficiency and robustness. A brief example application from the geophysics literature is also provided.

description: Este artículo presenta un panorama general sobre el romance y otras series monorrimas en la literatura catalana de los siglos XIV-XVI. El heptasílabo catalán, equivalente del octosílabo castellano, se documenta en la lírica catalana ya desde sus orígenes, pero entonces no estaba vinculado al romancero sino a formas estróficas con rimas consonantes y estribillo. Los primeros romances en catalán datan del siglo XVI, están dispuestos en coplas heptasilábicas con estribillo y parecen ser el resultado de una progresiva adaptación de estructuras autóctonas (la dansa, los goigs o las cobles) a un esquema monorrimo. Ninguno de los poemas analizados en este artículo denota una dependencia clara de los modelos temáticos y expresivos del romancero castellano, por lo que el autor formula la hipótesis de que dicha influencia, incuestionable en el romancero catalán contemporáneo, no se generalizó hasta el siglo XVII, justo cuando los poetas barrocos comenzaron a escribir romances en catalán.

Subjects: Community/Rural/Urban Development

description: The very purpose of this study is to, first, classify rural areas and then following this classification scheme, delve into their area-specific characteristics, especially concentrating upon their relationships to cities. Upon factor analysis, non-agricultural regional-economic factors, urban area factors, and suburbanization factors are found to be major determinants in classifying rural areas. Accordingly rural areas in Korea are classified into four major groupings; rural areas with strong emphasis on non-agricultural sector, areas with high degree of self-sufficiency, areas with strong interaction with cities, and finally, typical rural areas. Finally, after studying and comparing their characteristics, such as demography, farming households, and land uses, strong interaction with cities is judged not to be a propellant of their growth.

Note on CKM Matrix Renormalization

description: A simple inspection of the one loop quark self-energy suggests a prescription of the CKM matrix renormalization in the standard model. It leads to a CKM matrix counterterm which is gauge parameter independent and satisfies the unitarity constraint, and renormalized physical amplitudes which are gauge parameter independent and smooth in quark mass difference. We make a point that caution should be practiced when interpreting the CKM martix counterterm in terms of those of parameters in a given representation due to rephasing effects from renormalization. We show how this can be done using the degrees of freedom in the on-shell renormalization scheme.

Subjects: Agribusiness

description: The purpose of the present study is to identify agricultural niche goods in rural development strategies. We utilize the 2000 Korea Agricultural Survey, which in general has been in very limited use due to the fact of categorical sales variable. We create a new agricultural sales variable which enable us to get much more variability than it was categorized. The present study particularly concerns on the effects of environmental agriculture and computer usage on agricultural sales earnings. We found that environmental agriculture has negative effects on agricultural sales earnings. This is problematic, since environmental agriculture is regarded as one of the possible salvages for the Korean agriculture in the global system represented by the WTO. However, as expected, computer usage and it's application are proved to be positively associated with the agricultural sales earnings. The present study concludes with suggesting some policy issues for the future of agriculture and rural development in the 21st century for Korea.
Determinants of investment in Bulgarian family farming

description: This paper documents a relationship between non-farm income (primarily earnings and pensions) and agricultural outlays in Bulgaria, using the 2003 Multitopic Household Survey. The outcomes analyzed are expenditures on working capital (variable inputs such as feed, seed, and herbicides) and investment in livestock. I find that while non-farm income has no significant effect on the probability of purchasing variable inputs, it does have an effect on the amount spent if positive, with an estimated elasticity of 0.14. Non-farm income also has an effect on the number of households that purchase farm animals, with an estimated elasticity of 0.35. The use of non-farm income for farm investment is consistent with the presence of credit constraints, as is the fact that less than one per cent of farmers report outstanding debts for agricultural purposes. Yet it is also noted that many farm households take out large unsecured loans for other purposes, suggesting that a lack of demand for agricultural borrowing may also be part of the problem.

description: This paper investigates the impact of migration and remittances on asset holdings, consumption expenditures, and credit constraint status of households in origin communities, using a unique longitudinal data set from the Philippines. The Bukidnon Panel Study follows up 448 families in rural Mindanao who were first interviewed in 1984/85 by the International Food Policy Research Institute and the Research Institute for Mindanao Culture, Xavier University. The study interviewed the original respondents and a sample of their offspring, both those who have remained in the same area and those who have moved to a different location. This paper examines the impact of remittances from outside the original survey villages on parent households, taking into account the endogeneity of the number of migrants and remittances received to characteristics of the origin households and communities, completed schooling of sons and daughters, and shocks to both the origin households and migrants. When both migration and remittances are treated as endogenous, a larger number of migrant children reduces the values of nonland assets, total expenditures per adult equivalent, and some components of household expenditures. On the other hand, remittances have a positive impact on housing and consumer durables, nonland assets, and total expenditures (per adult equivalent). The largest impact of remittances is on the total value of nonland assets (driven by increased acquisition of consumer durables) and on educational expenditures. Thus, despite the costs that parents may incur in sending migrants to other communities, the returns, in terms of remittances, play an important role in enabling investment in assets and human capital in sending communities. Neither migration nor remittances affects current credit constraint status.

description: Previous studies have revealed a population of galaxies in galaxy clusters with ram pressure stripped (RPS) tails of gas and embedded young stars. We observed 1.4 GHz continuum and HI emission with the Very Large Array in its B-configuration in two fields of the Coma cluster to study the radio properties of RPS galaxies. The best continuum sensitivities in the two fields are 6 and 8 $μ$Jy per 4'' beam respectively, which are 4 and 3 times deeper than those previously published. Radio continuum tails are found in 10 (8 are new) out of 20 RPS galaxies, unambiguously revealing the presence of relativistic electrons and magnetic fields in the stripped tails. Our results also hint that the tail has a steeper spectrum than the galaxy. The 1.4 GHz continuum in the tails is enhanced relative to their H$α$ emission by a factor of $\sim$7 compared to the main bodies of the RPS galaxies. The 1.4 GHz continuum of the RPS galaxies is also enhanced relative to their IR emission by a factor of $\sim$2 compared to star-forming galaxies. The enhancement is likely related to ram pressure and turbulence in the tail. We furthermore present HI detections in three RPS galaxies and upper limits for the other RPS galaxies. The cold gas in D100's stripped tail is dominated by molecular gas, which is likely a consequence of the high ambient pressure. No evidence of radio emission associated with ultra-diffuse galaxies is found in our data.

We prove that the space of degree $d$ real branched coverings having "many" real branched points (for example more than $\sqrt{d}^{1+α}$, for any $α>0$) has exponentially small measure. In particular, maximal real branched coverings, that is real branched coverings such that all the branched points are real, are exponentially rare.

description: In developing countries, when markets are incomplete migration can have multiple effects on agricultural production. In this paper, I use instrumental variables techniques to explore the effects of seasonal migration on agricultural production in rural Viet Nam during the 1990s. Instrumenting migration with network variables specific to Vietnam, I find that migration shapes agricultural production is several ways. Although there are no effects of migration on aggregate production, there is weak evidence that migrant households move somewhat out of rice production and into the production of other crops. Inputs used by migrant households also decrease relative to similar non-migrant households. In exploring the mechanisms by which these changes occur, I find evidence consistent with a move from labor intensive into land intensive crops, rather than productivity changes or a shift from using labor to capital as an input.

description: Current-induced magnetization switching by spin-orbit torque (SOT) holds considerable promise for next generation ultralow-power memory and logic applications. In most cases, generation of spin-orbit torques has relied on an external injection of out-of-plane spin currents into the magnetic layer, while an external magnetic field along the electric current direction is generally required for realizing deterministic switching by SOT. Here, we report deterministic current-induced SOT full magnetization switching by lateral spin-orbit torque in zero external magnetic field. The Pt/Co/Pt magnetic structure was locally annealed by a laser track along the in-plane current direction, resulting in a lateral Pt gradient within the ferromagnetic layer, as confirmed by microstructure and chemical composition analysis. In zero magnetic field, the direction of the deterministic current-induced magnetization switching depends on the location of the laser track, but shows no dependence on the net polarization of external out-of-plane spin currents. From the behavior under external magnetic fields, we identify two independent mechanisms giving rise to SOT, i.e. the lateral Pt-Co asymmetry as well as out-of-plane injected spin currents, where the polarization and the magnitude of the SOT in the former case depends on the relative location and the laser power of the annealing track. Our results demonstrate an efficient field-free deterministic full magnetization switching scheme, without requiring out-of-plane spin current injection or complex external stack structures.

The Battery Rickshaw "Crisis" in New Delhi
Creators: name: Harding, Simon
Publisher: name: The University of British Columbia

description: This paper uses a case study of battery rickshaws in New Delhi as a lens through which to view the policy making process in urban India. Battery rickshaws are small public transport vehicles that typically transport passengers to and from metro stations for a small fare. In 2010 there were a few dozen in New Delhi; by 2014, estimates put their numbers at around 100,000. Despite their proliferation, the process of constructing an appropriate regulatory framework has been lengthy, antagonistic and dysfunctional, prompting the use of the term “crisis”. This paper briefly discusses the negative perceptions of battery rickshaws in New Delhi, which focus on the idea of informality. It then gives an account of the history of the “crisis”. The fourth section then identifies two factors which, it argues, are significant causes of this “crisis”: a) the polycentric nature of urban policy making and b) a lack of data upon which to base decisions. It concludes by following Roy’s (2007) contention that the policy making process can, itself, often be accurately termed informal.

Erect to decumbent, perennial herb, often much-branched and with many flowers; taproot strong; bladder cells bulging, globose to slightly conical (the latter only on shoots), loose to dense cover of the surface of internodes, leaves and outside of flowers; internodes can be reddish and are usually rough from bladder cells when young, later becoming smooth and also lignifying slightly. Leaves short (∼ 10 mm long) and narrow-elliptic; very succulent with semi-terete cross section; usually appearing revolute when dry. Bracts ca. 1 mm long and lanceolate; one pair. Flowers 4–6 mm long, sessile, tepals (narrow-) triangular; tepal teeth short and inconspicuous. Stamens numerous; thecae pinkish. Ovary with 2–3 carpels and the same number of styles. Fruit a many-seeded capsule. Seeds 0.9 mm long, elongate-reniform, laterally rounded, with a black, (almost) smooth, lustrous, and slightly iridescent testa.
Distribution and Habitat — The species is present in Angola (Fig. 5A) and found in coastal areas. It grows on sand or gravely soil.
Notes — It differs from the other Angolan Sesuoium species by its shrubby habit and two to three locules. C 4 species (Bohley et al. 2015). Halimus congense (Welw. ex Oliv.) O. Kuntze is an illegitimate combination.

description: This paper uses a duration analysis based on adoption data spanning over 25 years from six communities in the Central Highlands of Guatemala to explore how household characteristics and external trends play into both the adoption and diffusion processes of non-traditional exports among smallholders. Adoption was initially widespread and rapid, which led NTX to be hailed as a pro-poor success, reaching all but the smallest landholders. However, over time, more than two-thirds of adopters eventually dropped out from NTX production. Based on the analysis, NTX production appeared to have delivered less prosperity to adopters than initially promised. Primarily better-endowed farmers were able to overcome the increasingly adverse conditions and, in the long-terms, institutions and policy interventions do not appear to have mitigated these difficulties for less-endowed farmers. While poor farmers may be enticed into entering into NTX markets when conditions are favorable, they may lack the capacity to overcome difficulties that inevitably arise in complex types of cultivations and in highly variable global agricultural markets. Governmental and non-governmental organizations can attempt to mitigate these difficulties, but market forces may overwhelm these efforts, with poorer adopters still unable to compete in global markets.

Timing Analysis of the Isolated Neutron Star RX J0720.4-3125 Revisited

description: We present a reanalysis of the X-ray data for RX J0720.4-3125 presented in Zane et al. (2002), using more data recently available from XMM-Newton and Chandra. This analysis also corrects the Rosat data used in that paper to the TDB time system, incorporates the revised XMM-Newton barycentric correction available since then, and corrects the definition of the instantaneous period in the maximum likelihood periodogramme search. However, we are now unable to find a single coherent period that is consistent with all Rosat, Chandra and XMM-Newton datasets. From an analysis of the separate datasets, we have derived limits on the period change of Pdot = 1.4+/-0.6x10^-13 s/s at 99% confidence level. This is stronger than the value presented in Zane et al. (2002), but sufficiently similar that their scientific conclusions remain unchanged. We examine the implications in more detail, and find that RX J0720.4-3125 can have been born as a magnetar provided that it has a young age of ~10^4 yr. A more conservative interpretation is that the field strength has remained relatively unchanged at just over 10^13 G, over the ~10^6 yr lifetime of the star.

Este último exemplar revela ainda outra edição insuspeitada com data anterior à indicada no frontispício, já que o seu cólofon (infelizmente danificado precisamente no lugar correspondente aos dois últimos algarismos do ano da impressão) exibe outro editor bem conhecido com atividade entre 1651 e 1675, Jerónimo Vilagrasa. Apresenta-se agora a descoberta feita em Aix, com uma nota resumida sobre a sua importância.

Halimum portulacastrum var. crithmoides (Welw.) Hiern, Cat. Afric. Pl. (Hiern) 1(2): 412. 1898.
— TYPE: ANGOLA. Loanda [Luanda], Welaeitsch 2386 (holotype: LISU 214648 digital image!; isotypes: B!, BM, BR, COI, K!).
Perennial, procumbent herb; internodes sometimes described to be red; bulging bladder cells on shoots, leaves and the outside of the flower (not on tepal teeth), dry material therefore whitish. Leaves linear, up to 70 mm long and narrow with an oval to terete cross section, leaf tip obtuse and petiole up to 8 mm long, but indistinct. Bracts in 2–4 pairs, 4–5 mm long, triangular, dark color when dry. Flowers large, 12–15 mm long, red, subsessile. Stamens numerous, less than the length of the perianth. Ovary with 3–5 carpels and the same number of styles. Fruit a many seeded capsule. Seeds ca. 1 mm long, rounded reniform and slightly flattened, smooth and black.
Distribution and Habitat — The species is found in Angola and may also be present in the Democratic Republic of the Congo (Fig. 5B). It is also introduced in Georgia, U. S. A. It grows in coastal areas and disturbed habitats on sandy soil.
Vernacular Names — Tropical seapurslane.
Notes — C 4 species (Bohley et al. 2015). We do not know if Sesuoium crithmoides established a stable population in Georgia and still can be found there. Despite its distinct morphology with linear, terete leaves and large, red flowers, the species is not often found in collections. Sesuoium crithmoides and S. mesembryanthemoides appear to share the same habitat as well as sharing several traits that separate them from the other African Sesuoium species.

description: This paper examines the relationship between rurality and poverty, and the role the agricultural sector can play in rural development, poverty reduction, and overall development. The historical views regarding the role of the primary sector in development are presented, and then using original data, the paper argues that there was an historical misjudgment against the primary sector that served as a foundation for anti-agricultural bias in public policy until the late 80's. Finally, this paper explains how under certain conditions territorial/regional development strategies may prosper, but in other conditions, particularly in the least-developed countries rural space, agriculture is still necessarily the starting point for rural development.
