description: This study aimed to examine the direct influence of native endothelium derived relaxing factor (EDRF) on renin secretion. To this end isolated mouse renal juxtaglomerular cells were cocultured with bovine aortic endothelial cells which produced and released significant amounts of EDRF as assayed by guanylate cyclase activities which were measured separately in endothelial and juxtaglomerular cells as well as in the cocultures of juxtaglomerular with endothelial cells. EDRF production was blunted in the absence of extracellular L-arginine and in the presence of N omega-nitro-L-arginine (L-NAG; 200 microM). Inhibition of endothelial EDRF production by removal of arginine or addition of L-NAG was associated with a significant decrease of renin secretion from the cocultures while the same regimen had no effect on renin secretion from JG cells alone. Exogenous generation of nitric oxide by the addition of sodium nitroprusside (100 microM) stimulated renin secretion in the cocultures both at normal and inhibited EDRF formation as well as from juxtaglomerular cells alone. These findings suggest that native EDRF released from vascular endothelial cells is a stimulatory signal for renin secretion from renal juxtaglomerular cells.

description: The effects of a nonselective beta-adrenergic blocking drug with beta-2 agonist activity (dilevalol 200 mg) on proteinuria and renal hemodynamics were evaluated in a double-blind crossover study versus an ACE inhibitor (enalapril 5 mg) in eight patients with glomerulonephritis, moderate renal function impairment and proteinuria greater than 1 g/24 hr. Patients were studied after a one week placebo phase while off all other medications, except steroids in a few cases, and after three weeks of treatment. A 10-day placebo washout perod was included between the various drug treatments. During each period renal hemodynamics were measured by clearance techniques, and urinary protein excretion as well as fractional clearance of albumin and IgG were determined. Both drugs reduced mean arterial pressure and proteinuria to a similar extent [mean arterial pressure: placebo 108 +/- 13 mm Hg; dilevalol 103 +/- 11 mm Hg (P less than 0.05); enalapril 103 +/- 12 mm Hg (P less than 0.05); protein excretion: placebo 5.1 +/- 4.2 g/day; dilevalol 3.3 +/- 3.0 g/day (P less than 0.05); enalapril 2.8 +/- 2.8 g/day (P less than 0.05)]. The antiproteinuric effect was greater with enalapril than dilevalol. Dilevalol reduced GFR [baseline inulin clearance: 73.3 +/- 38 ml/min/1.73 m2; after dilevalol: 63.3 +/- 28 ml/min/1.73 m2 (P less than 0.05)] and the decrease of proteinuria correlated positively with the reduction of GFR. Enalapril did not significantly lower the GFR (inulin clearance during enalapril 66.8 +/- 23 ml/min/1.73 m2) and the reduction of proteinuria did not correlate with the lowering of the GFR.(ABSTRACT TRUNCATED AT 250 WORDS)

description: Across the Pacific, youth unemployment is regarded by governments, donors and citizens as one of the region’s key concerns, not only because of its effect on economic advancement, but also because of a perceived association between joblessness and insecurity, including the prospect of youth-driven crime and violence. Over the last two decades, increased scholarly attention has been paid to the link between youth unemployment and issues of social instability, most famously heralded by Henrik Urdal and his ‘youth bulge’ theory (2004). While issues of causation can be difficult to assess, the Pacific, particularly Melanesia, has seen this narrative take place in tandem with, or because of, rapid urbanisation which has been characterised by a growing cohort of unemployed or underemployed, urban youth. This scenario has been particularly true for Honiara, the capital of Solomon Islands.

description: We present a simple criterion, only based on second moment assumptions, for the convergence of polynomial or Wiener chaos to a Gaussian limit. We exploit this criterion to obtain new Gaussian asymptotics for the partition functions of two-dimensional directed polymers in the sub-critical regime, including a singular product between the partition function and the disorder. These results can also be applied to the KPZ and Stochastic Heat Equation. As a tool of independent interest, we derive an explicit chaos expansion which sharply approximates the logarithm of the partition function.

description: Spin-hosting graphene nanostructures are promising metal-free systems for elementary quantum spintronic devices. Conventionally, spins are protected from quenching by electronic bandgaps, which also hinder electronic access to their quantum state. Here, we present a narrow graphene nanoribbon substitutionally doped with boron heteroatoms that combines a metallic character with the presence of localized spin 1/2 states in its interior. The ribbon was fabricated by on-surface synthesis on a Au(111) substrate. Transport measurements through ribbons suspended between the tip and the sample of a scanning tunnelling microscope revealed their ballistic behavior, characteristic of metallic nanowires. Conductance spectra show fingerprints of localized spin states in form of Kondo resonances and inelastic tunnelling excitations. Density functional theory rationalizes the metallic character of the graphene nanoribbon due to the partial depopulation of the valence band induced by the boron atoms. The transferred charge builds localized magnetic moments around the boron atoms. The orthogonal symmetry of the spin-hosting state's and the valence band's wavefunctions protects them from mixing, maintaining the spin states localized. The combination of ballistic transport and spin localization into a single graphene nanoribbon offers the perspective of electronically addressing and controlling carbon spins in real device architectures.

description: In this paper, a novel method is proposed to extract rocks from Martian surface images by using 8 data field. It models the interaction between two pixels of an image in the context of imagery 9 characteristics. First, foreground rocks are differed from background information by binarizing 10 image on roughly partitioned images. Second, foreground rocks are grouped into clusters by 11 locating the centers and edges of clusters in data field via hierarchical grids. Third, the target 12 rocks are discovered for the Mars Exploration Rover (MER) to keep healthy paths. The 13 experiment with images taken by MER shows the proposed method is practical and potential.

description: The rice bacterial blight caused by Xanthomonas oryzae pv. oryzae (Xoo) bacteria is rice’s most destructive disease. Due to the potential biomagnification caused by bactericides, deploying host resistance is the most effective method to protect the rice harvest. Studying the pathogenicity structure of the Xoo population helps propose the best breeding strategies to use the resistance gene pool. Among 12 resistance genes validated, xa5 and Xa21 maintained their efficacy against the Xoo population in Vietnam. Other genes, including Xa7 and xa13, remained effective in certain regions. The most destructive Xoo races distribute in the South, where intensive rice production was practiced. The same Xoo races found in different ecological regions illustrated the pathogen migration between adjacent areas. This manuscript proposed a designation system that converts the response of the differential set to each Xoo isolate into a binary, then into an octal system to name Xoo races appropriately.

Graph Orientations and Linear Extensions

description: Given an underlying undirected simple graph, we consider the set of all acyclic orientations of its edges. Each of these orientations induces a partial order on the vertices of our graph and, therefore, we can count the number of linear extensions of these posets. We want to know which choice of orientation maximizes the number of linear extensions of the corresponding poset, and this problem will be solved essentially for comparability graphs and odd cycles, presenting several proofs. The corresponding enumeration problem for arbitrary simple graphs will be studied, including the case of random graphs; this will culminate in 1) new bounds for the volume of the stable polytope and 2) strong concentration results for our main statistic and for the graph entropy, which hold true $a.s.$ for random graphs. We will then argue that our problem springs up naturally in the theory of graphical arrangements and graphical zonotopes.

LLT cumulants and graph coloring

Subjects: subject: Combinatorics (math.CO)

description: The purpose of this note is to introduce a new family of quasi-symmetric functions called LLT cumulants and discuss its properties. We define LLT cumulants using the algebraic framework for conditional cumulants and we prove that the Macdonald cumulant has an explicit positive expansion in terms of LLT cumulants of ribbon shapes, generalizing the classical decomposition of Macdonald polynomials. We also find a natural combinatorial interpretation of the LLT cumulant of a given directed graph as a weighted generating function of colorings of its subgraphs. We use this graph theoretical framework to prove various positivity results. This includes monomial positivity, positivity in fundamental quasisymmetric functions and related positivity of the coefficients of Schur polynomials indexed by hook shapes. We also prove $e$-positivity for vertical-shape LLT cumulants, after the shift of variable $q \to q+1$, which refines a recent result of Alexandersson and Sulzgruber. All these results give evidence towards Schur-positivity of LLT cumulants, which we conjecture here. We prove that this conjecture implies Schur-positivity of Macdonald cumulants, and we give more evidence by proving the conjecture for LLT cumulants of melting lollipops that refines a recent result of Huh, Nam and Yoo.

description: The handling of low, middle and high molecular weight markers was examined in seven stable dialysis patients during hemofiltration with different membranes. Four membranes were examined in a randomized, crossover order (polysulfone, polyamide, AN69 polyacrylonitrile, Asahi polyacrylonitrile) by measuring plasma and dialysate concentrations of phosphate, creatinine, vitamin B12, beta 2-microglobulin, furanic acid, hippuric acid, retinol-binding protein, alpha-1-antitrypsin, and albumin. Sieving coefficients and plasma clearances of beta 2-microglobulin or retinol-binding protein were markedly or slightly lower during hemofiltration with the Asahi polyacrylonitrile membrane than with the other membranes (highest removal with polysulfone/AN69 polyacrylonitrile membranes). No differences of obvious clinical relevance could be seen between the four membranes. A high beta 2-microglobulin removal rate might be important to prevent dialysis-associated amyloidosis.

description: In electrostatics, we can use either potential energy or field energy to ensure conservation of energy. In electrodynamics, the former option is unavailable. To ensure conservation of energy, we must attribute energy to the electromagnetic field and, in particular, to electromagnetic radiation. If we adopt the standard energy density for the electromagnetic field, then potential energy seems to disappear. However, a closer look at electrodynamics shows that this conclusion actually depends on the kind of matter being considered. Although we cannot get by without attributing energy to the electromagnetic field, matter may still have electromagnetic potential energy. Indeed, if we take the matter to be represented by the Dirac field (in a classical precursor to quantum electrodynamics), then it will possess potential energy (as can be seen by examining the symmetric energy-momentum tensor of the Dirac field). Thus, potential energy reappears. Upon field quantization, the potential energy of the Dirac field becomes an interaction term in the Hamiltonian operator of quantum electrodynamics.

description: Implementation of the hardcore-dimer Hilbert space in cold Rydberg-atom simulators opens a new route of investigating real-time dynamics of dimer liquids under Hamiltonian quench. Here, we consider an initial Resonating Valence Bond (RVB) state on the square lattice realizing a critical Coulomb phase with algebraic and dipolar correlations. Using its representation as a special point of a broad manifold of SU($2$)-symmetric, translationnally invariant, Projected Entangled Pair States (PEPS), we compute its non-equilibrium dynamics upon turning on inter-site Heisenberg interactions. We show that projecting the time-evolution onto the PEPS manifold remains accurate at small time scales. We also find that the state evolves within a PEPS sub-manifold characterized by a U($1$) gauge symmetry, suggesting that the Coulomb phase is stable under such unitary evolution.

description: Endothelin-1 (ET-1) is known to have strong vasoactive properties. Contradictory results have been reported with regard to its inotropic effects. This study examined the dose-dependent (500, 1000, 2500, 5000 and 10,000 ng ET-1/kg vs. NaCl controls) hemodynamic and inotropic effects of ET-1 in 53 open-chest rats during and after a 7-min infusion. Besides measurements in the intact circulation the myocardial function was examined by isovolumic registrations independent of peripheral vascular effects. A transient ET-1 induced (500, 1000, 2500, 5000 ng ET-1/kg) decrease of the left ventricular systolic pressure (LVSP) and the mean aortic pressure (AoPmean) was followed by a dose-related rise of these pressures (LVSP: -1%, -1%, +8%, +16% vs. preinfusion values; AoPmean: -11%, +9%, +39%, +52%). Heart rate (HR) was not influenced by ET-1. Due to the dose-dependent decrease of the stroke volume (SV) the cardiac output (CO) was reduced (CO: -8%, -23%, -40%, -50%). After an initial vasodilatation ET-1 elevates the total peripheral resistance (TPR: -1%, +49%, +139%, +215%) dose-dependently. 10,000 ng ET-1/kg was a lethal dose resulting in cardiac failure within minutes (low output). Since the maximum of the isovolumic LVSP (peak LVSP) and the corresponding dP/dtmax (peak dP/dtmax) were unchanged under ET-1, the isovolumic measurements do not indicate a positive inotropic effect of ET-1 in vivo in contrast to published results of in vitro experiments. It may be possible that a direct positive inotropic effect of ET-1 observed in in vitro studies is counterbalanced in vivo by an indirect negative inotropic effect due to the coronary-constrictive effect of ET-1.

description: The black hole scalarization in a special Einstein-scalar-Gauss-Bonnet (EsGB) gravity has been widely investigated in recent years. Especially, the spontaneous scalarization of scalar-free black hole in de-Sitter (dS) spacetime possesses interesting features due to the existence of cosmological horizon. In this work, firstly, we focus on the massive scalar field perturbation on Schwarzschild dS (SdS) black hole in a special EsGB theory. By analyzing the fundamental QNM frequency and time evolution of the scalar field perturbation, we figure out the unstable/stable regions in $(Λ,α)$-plane as well as in $(m,α)$-plane for various perturbation modes, where $Λ$, $α$ and $m$ denote the cosmological constant, the GB coupling strength and the mass of scalar field, respectively. Then by solving the static perturbation equation, we analyze the bifurcation point at which the SdS black hole supports spherical scalar clouds, and we find that the bifurcation points match well with $α_c$ on the border of unstable/stable region. Finally, after addressing that the scalarised solutions could only emerge from the scalar could with node $k\geq 1$. we explicitly construct the scalarized hairy solutions for different scalar masses and compare the profile of scalar field to the corresponding scalar clouds.

description: Roughly 40% of all patients with insulin-dependent diabetes mellitus (IDDM) develop diabetic nephropathy with proteinuria, hypertension and a decrease in glomerular filtration rate 10 to 20 years after the onset of the disease, and 5 years later most patients suffer from end-stage renal disease. Microalbuminuria, defined as an urinary albumin excretion rate (UAER) between 30 and 300 mg/day, strongly predicts the development of nephropathy in IDDM. Nearly all patients with IDDM, a decreasing glomerular filtration rate and a UAER > 300 mg/day have coexisting hypertensive disease additionally worsening renal function. We review the results of recent long-term studies of the current therapeutic management in diabetic patients by means of better blood pressure control, low-protein diet and near-normal blood glucose control in the early microalbuminuric phase as well as in the later phases of the disease characterized by diabetic nephropathy with a UAER > 300 mg/day. Since the large majority of studies have been performed on IDDM, our conclusions with regard to therapy are only valid in this subgroup of diabetic patients.

Anthony Regan, to cite one instance, has argued that there was intended to be ‘a radical redistribution of power, requiring the creation of new centres of power able to act as a counterbalance to the central government as well as operate as new arenas for resolution of local tensions and disputes’ (1992:9). Instead, here it is argued that the principal determinant of the constitutional reforms was the continuing drive by indigenes to open up space in the postcolonial state so that their hold on political power could be transformed into commercial opportunities.

description: In this paper, we compute the one-level density of low-lying zeros of Dirichlet $L$-functions in a family weighted by special values of Dirichlet $L$-functions at a fixed $s \in [1/2, 1)$. We verify both Fazzari's conjecture and the first author's conjecture on the weighted one-level density for our family of $L$-functions.

A phase transition for $q$-TASEP with a few slower particles
Creators: name: Barraquand, Guillaume
Publisher: name: arXiv
Year: 2014
Subjects: subject: Probability (math.PR)
subject: FOS: Mathematics

description: We consider a $q$-TASEP model started from step initial condition where all but finitely many particles have speed $1$ and a few particles are slower. It is shown in [9] that the rescaled particles position of $q$-TASEP with identical hopping rates obeys a central limit theorem à la Tracy-Widom. We adapt this work to the case of different hopping rates and show that one observes the so-called BBP transition. Our proof is a refinement of Ferrari-Vetö's and does not require any condition on the parameter $q$ nor the macroscopic position of particles.

description: We determine the most general form of a smooth function on Young diagrams, that is, a polynomial in the interlacing or multirectangular coordinates whose value depends only on the shape of the diagram. We prove that the algebra of such functions is isomorphic to quasi-symmetric functions, and give a noncommutative analog of this result.

Sharing the City: Urban Growth and Governance in Suva, Fiji

description: Fiji is the most urbanised state in Melanesia. Its main city, Suva, is facing many challenges of rapid growth. With more than 50 per cent of its population now living in its cities and that number set to increase to about 60 per cent in the next decade (UN-Habitat 2012a), Suva officials and residents are working to address the pressures of urbanisation and to capitalise on its opportunities. Rapid growth has given rise to familiar urban problems in Suva, including unemployment, poverty, informal settlements and patchy services — about a fifth of the Greater Suva residents live in informal or squatter settlements,1 many in poverty with poor services and connectivity to the city. Yet despite the inequities and service gaps, positive gains from urbanisation are being made in Suva. The challenge for urban managers and residents is to capitilise on the potential of cities to boost productivity, connectivity and infrastructure coverage while better managing emerging social, cultural and service delivery divides. There are some positive signs. While unemployment in Fiji is high, at about 7.6 per cent, it is declining; Suva remains a strong driver of national economic growth, accounting for about a third of gross domestic product (GDP); and while urban poverty persists, it is falling (World Bank 2014). Moreover, emerging institutional arrangements are attempting to reconcile the impetus for growth with customary values and land tenure. As part of a broader study of urbanisation by the State, Society and Governance in Melanesia (SSGM) program at the Australian National University, this paper outlines some of the tensions and innovations that have occurred in Suva with respect to urban development and informal settlements over the last decade. ‘Informal settlements’ is an umbrella term used in this paper to encompass settlements of ‘squatters’ (the vernacular term for those who reside on freehold or state land without legal title), and people who have made informal arrangements with owners to reside on customary land. Both situations tend to mushroom in rapidly urbanising contexts, and Fiji’s attempts to grapple with this and other urban issues might be applicable across the Pacific region. The research involved reviewing government documents and literature, and conducting interviews with high-level government officials in the Ministry of Lands, Department of Housing, Suva City Council and Nausori Town Council, as well as with key community stakeholders. We consider the lessons that can be learnt from Suva’s experiences and the challenges that lie ahead. In particular, we are concerned with addressing issues of exclusion, inequality, and access to urban land and shelter

description: We investigate the free fields realization of the twisted Heisenberg-Virasoro algebra $\mathcal{H}$ at level zero. We completely describe the structure of the associated Fock representations. Using vertex-algebraic methods and screening operators we construct singular vectors in certain Verma modules as Schur polynomials. We completely solve the irreducibility problem for tensor product of irreducible highest weight modules with intermediate series. We also determine the fusion rules for an interesting subcategory of $\mathcal{H}$-modules. Finally, as an application we present a free field realization of the $W(2,2)$-algebra and interpret the $W(2,2)$-singular vectors as $\mathcal{H}$-singular vectors in Verma modules.
