Active particles in geometrically confined viscoelastic fluids

description: We experimentally study the dynamics of active particles (APs) in a viscoelastic fluid under various geometrical constraints such as flat walls, spherical obstacles and cylindrical cavities. We observe that the main effect of the confined viscoelastic fluid is to induce an effective repulsion on the APs when moving close to a rigid surface, which depends on the incident angle, the surface curvature and the particle activity. Additionally, the geometrical confinement imposes an asymmetry to their movement, which leads to strong hydrodynamic torques, thus resulting in detention times on the wall surface orders of magnitude shorter than suggested by thermal diffusion. We show that such viscoelasticity-mediated interactions have striking consequences on the behavior of multi-AP systems strongly confined in a circular pore. In particular, these systems exhibit a transition from liquid-like behavior to a highly ordered state upon increasing their activity. A further increase in activity melts the order, thus leading to a re-entrant liquid-like behavior.

description: During Africa's first two decades of independence from 1960 to 1980, priority was given to increasing the size of national extension services because it was assumed that technology could be imported from industrial countries and the International Agricultural Research Centers. Over the past decade, donors have turned their attention to assisting national agricultural research systems (NARS). But many NARS are performing poorly and are faced with a high turnover of scientific staff and inadequate operating budgets. Moreover, the present donor-financed project by project and country by country approach to building African scientific capacity is seriously flawed. This paper examines Africa's agricultural research history over the past six decades and draws lessons for strengthening national and regional agricultural research systems over the coming 30 years.

Risk and Uncertainty

description: The paper mustrates the scope for enhancing the conceptual apparatus used by agricultural economists to analyse decision-making under conditions of uncertainty. Selected empirical results from experiments on student subjects from three universities are reported. Three issues are considered. First, the reasons for choice and the understanding of a choice problem are examined. Second, attitudes towards different levels of uncertainty are measured. Third, the possibility that apparently non-normative psychological factors influence choice is explored. The paper serves to illustrate and support a number of methodological points. The major points are that a risk-uncertainty distinction is useful (contrary to the aging conventional wisdom of economic theory), that laboratory experiments can potentially provide data of use to agricultural economists, and that predictive models of choice under uncertainty may be more accurate if they take account of psychological variables which influence the decision-making processes of human subjects.
Empirically Testing the Law of One Price in an International Commodity Market: A Rational Expectations Application to the Natural Rubber Market

description: The Law of One Price (LOP) is an important ingredient in theories of international trade and exchange rate determination. An important shortcoming of the existing empirical literature is that parity is typically assumed to hold contemporaneously. This overlooks the fact that international commodity arbitrage takes place over tim~> <<8 well as across spatially separated markets. Recognizing this fact, we expect to see parity holding for expected prices. A model which incorporates the expectations of commodity arbitragers is constructed and used to test the LOP in the natural rubber market. Results indicate that the inclusion of expectations may be of value when considering the LOP.
Approximation results in Orlicz spaces for sequences of Kantorovich max-product neural network operators

description: In this paper we study the theory of the so-called Kantorovich max-product neural network operators in the setting of Orlicz spaces $L^φ$. The results here proved, extend those given by Costarelli and Vinti in Result Math., 2016, to a more general context. The main advantage in studying neural network type operators in Orlicz spaces relies in the possibility to approximate not necessarily continuous functions (data) belonging to different function spaces by a unique general approach. Further, in order to derive quantitative estimates in this context, we introduce a suitable K-functional in $L^φ$ and use it to provide an upper bound for the approximation error of the above operators. Finally, examples of sigmoidal activation functions have been considered and studied in details.

 Triatoma gomeznunezi Martínez, Carcavallo & Juberg, 1994: 15; Carcavallo et al., 2000: 70; Galvão et al., 2003: 10; Schofield & Galvão, 2009: 92; Monteiro et al., 2018: 284.
 Diagnosis. Male body length 21.0 mm. Regular size eyes in dorsal view, synthlipsis wider than eye, and postocular region subequal to eye length. Clypeus, genae and jugae covered with conspicuous long pilosity. Antenniferous tubercle laterally covered with long setae and dorsally glabrous. Neck polished and entirely black. Posterior lobe of pronotum brownish, distinctly lighter than anterior lobe. Humeral angles rounded. Overall color of corium dark brown, with basal and subapical yellowish spots. Conexivum with segments black on anterior half and yellow on posterior half, extending to connexival suture.
 Specimens examined. None.
 Distribution. Mexico: Oaxaca (Galvão et al. 2003).
 Comments. There are no molecular studies available for this species. Martínez (1994) mentioned that T. gomeznunezi is similar to T. brailovsky in several morphological characters, except measures of head structures and shape of the scutella. Carcavalho et al. (2000) proposed that T. gomeznunezi is close to T. brailovsky, T. dimidiata, and T. hegneri, based on morphological similarities between these species without details. This statement was followed by Schofield & Galvão (2009), Georgieva et al. (2017) and Monteiro et al. (2018), who proposed that T. gomeznunezi is related to several species of the T. phyllosoma species group, without details of their decision. Here, we assume that T. gomeznunezi is related to the T. phyllosoma species group because it is morphologically close to T. brailovsky. This latter species is the sister taxon of the remaining species of the T. phyllosoma species group according to molecular data (Espinoza et al. 2013).

Dark Matter Profiles in Clusters of Galaxies: a Phenomenological Approach
Creators: name: Arieli, Yinon

Publisher: name: arXiv
Year: 2003
Subjects: subject: Astrophysics (astro-ph)

description: There are some basic differences between the observed properties of galaxies and clusters and the predictions from current hydrodynamical simulations. These are particularly pronounced in the central regions of galaxies and clusters. The popular NFW (Navarro, Frenk, and White) profile, for example, predicts a density cusp at the center, a behavior that (unsurprisingly) has not been observed. While it is not fully clear what are the reasons for this discrepancy, it perhaps reflects (at least partly) insufficient spatial resolution of the simulations. In this paper we explore a purely phenomenological approach to determine dark matter density profiles that are more consistent with observational results. Specifically, we deduce the gas density distribution from measured X-ray brightness profiles, and substitute it in the hydrostatic equilibrium equation in order to derive the form of dark matter profiles. Given some basic theoretical requirements from a dark matter profile, we then consider a number of simple profiles that have the desired asymptotic form. We conclude that a dark matter density profile of the form 1/(1+r/r_a)^3 is most consistent with current observational results.

description: Government's policy interventions in the market for food-grains affect supply as well as demand. In this paper, the welfare effects of certain food-grain policies are analysed while taking into account the interdependence of the various sectors in the economy. Adequate structure is built into the model in order to study the effects of a dual price structure on farmers' supply response, and also the effects of public distribution schemes on the aggregate demand for foodgrains. Policy implications are derived by computing the market clearing prices and their movement under alternative assumptions regarding the nature of the market.
Magnon-Mediated Superconductivity in Itinerant Ferromagnets
Creators: name: Karchev, N.
Publisher: name: arXiv
Year: 2002
Subjects: subject: Superconductivity (cond-mat.supr-con)
subject: FOS: Physical sciences

description: The present paper discusses magnon-mediated superconductivity in ferromagnetic metals. The mechanism explains in a natural way the fact that the superconductivity in UGe_2, ZrZn_2 and URhGe is apparently confined to the ferromagnetic phase.The order parameter is a spin anti-parallel component ofa spin-1 triplet with zero spin projection. The transverse spinfluctuations are pair forming and the longitudinal ones are pair breaking.The competition between magnons and paramagnons explains the existence of two successive quantum phase transitions in UGe_2, from ferromagnetism to ferromagnetic superconductivity, and at higher pressure to paramagnetism. The maximum T_{SC} results from the suppression of the paramagnon contribution. To form a Cooper pair an electron transfers from one Fermi surface to the other. As a result, the onset of superconductivity leads to the appearance of two Fermi surfaces in each of the spin up and spin down momentum distribution functions. This fact explains the linear temperaturedependence at low temperature of the specific heat, and the experimental results for UGe_2.

 Diagnosis. Male body length 18.0– 20.5 mm. Female body length 18.5–22.0 mm. Postocular region distinctly rounded in dorsal view. Neck with 1+1 lateral reddish or yellow spots. Pronotum uniformly piceous or black. Humeral angles rounded. Hemelytra dark brown or piceous, with lighter markings on corium basally and subapically, as well as on clavus. Fore femora stout, about six times as long as wide. Fore and mid tibiae of male with small spongy fossula, absent in female. Overall color of connexival segments piceous to black, with reddish marking extending on posterior suture, very narrow about sixth or seventh of each connexival segment.
 Specimens examined. None.
 Distribution. Mexico: Chihuahua and Sinaloa; and USA: Arizona, New Mexico, and Texas (Galvão et al. 2003; Bern et al. 2011).
 Comments. This species was related to T. lecticularia and T. sanguisuga (Lent & Wygodzinsky 1979; Schofield & Galvão 2009). Besides, T. indictiva might be morphologically closer to T. sanguisuga than to T. lecticularia because it was considered a subspecies of T. sanguisuga early (Usinger 1944).According to ultraconserved elements of molecular data, T. indictiva belongs to the T. phyllosoma species group (Kieran et al. 2021).

description: The first complete and explicit SO(1,9) Lorentz descriptions of all component fields contained in $\mathcal{N} = 1$, $\mathcal{N} = 2$A, and $\mathcal{N} = 2$B unconstrained scalar 10D superfields are presented. These are made possible by the discovery of the relation of the superfield component expansion as a consequence of the branching rules of irreducible representations in one ordinary Lie algebra into one of its Lie subalgebras. Adinkra graphs for ten dimensional superspaces are defined for the first time, whose nodes depict spin bundle representations of SO(1,9). An analog of Breitenlohner's approach is implemented to scan for superfields that contain graviton(s) and gravitino(s), which are the candidates for the prepotential superfields of 10D off-shell supergravity theories and separately abelian Yang-Mills theories are similarly treated. Version three contains additional content, both historical and conceptual, which broaden the reach of the scan in the 10D Yang-Mills case.

description: We report new radial velocity observations of GP Vel/HD77581, the optical companion to the eclipsing X-ray pulsar Vela X-1. Using data spanning more than two complete orbits of the system, we detect evidence for tidally induced non-radial oscillations on the surface of GP Vel, apparent as peaks in the power spectrum of the residuals to the radial velocity curve fit. By removing the effect of these oscillations (to first order) and binning the radial velocities, we have determined the semi-amplitude of the radial velocity curve of GP Vel to be K_o=22.6+/-1.5 km/s. Given the accurately measured semi-amplitude of the pulsar's orbit, the mass ratio of the system is 0.081+/-0.005. We are able to set upper and lower limits on the masses of the component stars as follows. Assuming GP Vel fills its Roche lobe then the inclination angle of the system, i=70.1+/-2.6 deg. In this case we obtain the masses of the two stars as M_x=2.27 +/-0.17 M_sun for the neutron star and M_o=27.9+/-1.3 M_sun for GP Vel. Conversely, assuming the inclination angle is i=90 deg, the ratio of the radius of GP Vel to the radius of its Roche lobe is beta=0.89+/-0.03 and the masses of the two stars are M_x=1.88+/-0.13 M_sun and M_o=23.1+/-0.2 M_sun. A range of solutions between these two sets of limits is also possible, corresponding to other combinations of i and beta. In addition, we note that if the zero phase of the radial velocity curve is allowed as a free parameter, rather than constrained by the X-ray ephemeris, a significantly improved fit is obtained with an amplitude of 21.2+/-0.7 km/s and a phase shift of 0.033+/-0.007 in true anomaly. The apparent shift in the zero phase of the radial velocity curve may indicate the presence of an additional radial velocity component at the orbital period.

description: We consider a class of cosmological models in which the universe is filled with a (non-electric) charge density that repels itself by means of a force carried by a vector boson with a tiny mass. When the vector's mass depends upon other fields, the repulsive interaction gives rise to an electromagnetic barrier which prevents these fields from driving the mass to zero. This can modify the cosmology dramatically. We present a very simple realization of this idea in which the vector's mass arises from a scalar field. The electromagnetic barrier prevents this field from rolling down its potential and thereby leads to accelerated expansion.

description: Context. Only a few open clusters are as important for the study of stellar and substellar objects, and their formation and evolution, as the young sigma Orionis cluster. However, a complete spectroscopic characterisation of its whole stellar population is still missing. Aims. We filled most of that gap with a large spectroscopic and astrometric survey of targets towards sigma Orionis. Eventually, it will be one of the open clusters with the lowest proportion of interlopers and the largest proportion of confirmed cluster members with known uncontrovertible youth features. Methods. We acquired 317 low-resolution optical spectra with the Intermediate Dispersion Spectrograph (IDS)} at the 2.5 m Isaac Newton Telescope (INT) and the Optical System for Imaging and low Resolution Integrated Spectroscopy (OSIRIS) at the 10.4 m Gran Telescopio Canarias (GTC). We measured equivalent widths of Li I, H-alpha, and other key lines from these spectra, and determined spectral types. We complemented this information with Gaia DR2 astrometric data and other features of youth (mid-infrared excess, X-ray emission) compiled with Virtual Observatory tools and from the literature. Results. Of the 168 observed targets, we determined for the first time spectral types of 39 stars and equivalent widths of Li I and H-alpha of 34 and 12 stars, respectively. We identified 11 close (rho

description: Oxidative stress and mitochondrial dysfunction are hypothesized to contribute to the pathogenesis of chronic cholestatic liver diseases. Silent information regulator 1 (SIRT1) attenuates oxidative stress and improves mitochondrial biogenesis in numerous mitochondrial-related diseases; however, a functional role for SIRT1 in chronic liver cholestasis, characterized by increased levels of toxic bile acids, remains unknown. We show decrease in SIRT1 levels and its activity and impairment of mitochondrial biogenesis in the liver of patients with extrahepatic cholestasis. Moreover, we found that glycochenodeoxycholic acid (GCDCA) stimulated cytotoxicity, disrupted the mitochondrial membrane potential, increased reactive oxygen species production, and decreased mitochondrial mass and mitochondrial DNA content in L02 cells. Consistent with this finding, GCDCA was found to decrease SIRT1 protein expression and activity, thus promoting the deacetylation of peroxisome proliferator-activated receptor gamma, coactivator 1 alpha (PGC-1α), a key enzyme involved in mitochondrial biogenesis and function. Conversely, GCDCA-induced mitochondrial injury was efficiently attenuated by SIRT1 overexpression. In summary, these findings indicate that the loss of SIRT1 may play a crucial role in the pathogenesis of liver damage observed in patients with extrahepatic cholestasis. The findings also indicate that genetic supplementation of SIRT1 can ameliorate GCDCA-induced hepatotoxicity through the activation of PGC-1α-dependent mitochondrial biogenesis.

description: We study the scattering problem for the nonlinear Schrödinger equation $i\partial_t u + Δu = |u|^p u$ on $\mathbb{R}^d$, $d\geq 1$, with a mass-subcritical nonlinearity above the Strauss exponent. For this equation, it is known that asymptotic completeness in $L^2$ with initial data in $Σ$ holds and the wave operator is well-defined on $Σ$. We show that there exists $0

description: Perfluorooctane sulfonate (PFOS), a member of the perfluorinated chemical family, has been convincingly demonstrated to affect lipid metabolism in animals and humans and readily crosses the placenta to exert its effects on the developing fetuses. While its exact mechanism is still not clear, PFOS exposure has long been suggested to exert its toxicity via oxidative stress and/or altered gene expression. Levels of PFOS and malondialdehyde in various organs and cell cultures have been widely determined as general indicators of non-specific lipid peroxidation after PFOS exposure. In this study, the oxidation of precise polyunsaturated fatty acids and their metabolites, derived from enzymatic and non-enzymatic pathways was determined following PFOS exposure in both adult and maternal/fetal mice. CD-1 mice were exposed to 3 mg/kg body weight/day of PFOS in corn oil by oral gavage until late gestation (GD17). We demonstrated that lipid peroxidation was particularly and exclusively affected in fetuses exposed to PFOS, but this was not the case in the maternal mice, where limited effects were observed in the enzymatic oxidation pathway. In this study, we demonstrated that PFOS-induced lipid peroxidation might have a greater impact in free radical generation in fetuses than in dams and could be responsible for affecting fetal development. In addition, antioxidant enzymes, such as superoxide dismutase and catalase, appeared to maintain oxidative stress homeostasis partially in adult mice exposed to PFOS. Taken together, our results might elucidate the mechanism of how PFOS induces oxidative stress in vivo.

description: The three-dimensional electronic structure and Ce 4f electrons of the heavy fermion superconductor CePt2In7 is investigated. Angle-resolved photoemission spectroscopy using variable photon energy establishes the existence of quasi-two and three dimensional Fermi surface topologies. Temperature-dependent 4d-4f on-resonance photoemission spectroscopies reveal that heavy quasiparticle bands begin to form at a temperature well above the characteristic (coherence) temperature T*. T* emergence may be closely related to crystal electric field splitting, particularly the low-lying heavy band formed by crystal electric field splitting.

description: A connection between the theory of neural networks and cryptography is presented. A new phenomenon, namely synchronization of neural networks is leading to a new method of exchange of secret messages. Numerical simulations show that two artificial networks being trained by Hebbian learning rule on their mutual outputs develop an antiparallel state of their synaptic weights. The synchronized weights are used to construct an ephemeral key exchange protocol for a secure transmission of secret data. It is shown that an opponent who knows the protocol and all details of any transmission of the data has no chance to decrypt the secret message, since tracking the weights is a hard problem compared to synchronization. The complexity of the generation of the secure channel is linear with the size of the network.

description: This research discusses the use of social norms marketing to improve responsible drinking among college students. It was observed in each year of research that students studied overestimated their peers’ drinking practices. During the social norms marketing campaign decreases were observed in both students’ self-reported number of drinks consumed and perceived number of drinks consumed by peers at bars or parties, indicating that the social norms marketing efforts were somewhat successful. In addition, students reported drinking less alcohol over a shorter period of time. However, some negative behaviors related to drinking did not improve.

description: This paper attempts to assess the link between poverty and efficiency in Ethiopia. Based on 214 households drawn from eight Peasant Associations (PAs) from two zones in Ethiopia’s Amhara National Regional State, the study measures the levels of poverty and efficiency, and assessed the link between the two. Both objective and subjective measures were used to measure the level of poverty, which was found to be 28% and 27% by both measures, respectively. While 35.6% of households were found to be poor in relative terms (using the Cost-of-Basic-Needs approach), 76.4% were poor in terms of the one-dollar-a-day absolute measure of poverty. The study also shows that there was wide variation in the level of poverty between the sample districts. The stochastic frontier distance function with variable return to scale specification reveals that all input variables, with the exception of ox power, significantly determine the efficient level of output. Whereas the average efficiency score of sample households was 62.8%, indicating the existence of technical inefficiency among farmers in the study areas, the mean efficiency score of poor and non-poor households was found to be 58.3% and 74.4%, respectively. The logistic regression also reveals that efficiency plays an important role in explaining the observed poverty incidences. Prediction of the marginal effects of a 10% improvement in efficiency reduced the probability of being poor by about 4%, while simulation of the effect of improved efficiency on poverty indicates that 14.1% of the poor households could get out of poverty by attaining a 25% improvement in the existing efficiency levels. The implication for policy is that improving access to resources without ensuring their efficient utilization could not have the desired impact in reducing poverty.
Energetics of rocked inhomogeneous ratchets

description: We study the efficiency of frictional thermal ratchets driven by finite frequency driving force and in contact with a heat bath. The efficiency exhibits varied behavior with driving frequency. Both nonmonotonic and monotonic behavior have been observed. In particular the magnitude of efficiency in finite frequency regime may be more than the efficiency in the adiabatic regime. This is our central result for rocked ratchets. We also show that for the simple potential we have chosen, the presence of only spatial asymmetry (homogeneous system) or only frictional ratchet (symmetric potential profile), the adiabatic efficiency is always more than in the nonadiabatic case.

description: Momentum resolved electron energy-loss spectroscopy was used to measure the dispersions of excitons in a free-standing monolayer of WSe2. Besides the parabolically dispersed valley excitons, a sub-gap dispersive exciton was observed at specific q values for the first time. The simultaneous STEM-ADF imaging of the local probed areas suggests that this sub-gap exciton is attributed to the prolific Se vacancies.

subject: Uganda

description: The study examines the determinants of improved agricultural technologies adoption in Uganda, using a nationally representative panel data set of 1,600 farming households, collected by the Ugandan Bureau of Statistics in 2005/6 and 2009/10. Two agricultural technologies—improved seeds and fertilizer—out of the seven types identified by the study were further considered and analyzed. Estimates from the probit regression model show that farmers with low education and land holdings are less likely to adopt improved seeds and fertilizer, while peer effects play a big role in influencing farmers to either use improved seeds or fertilizer. Furthermore, cattle keeping farmers in Western Uganda are more likely to abandon fertilizers and possibly resort to organic manure from livestock excreta. Policy, therefore, should be directed at addressing the supply side constraints of agricultural technologies.
