Subjects: subject: 610 Medical sciences Medicine

description: Das Risiko im Laufe seines Lebens an einer Leistenhernie zu erkranken ist mit knapp 30% für das männliche Geschlecht hoch, die Leistenhernienoperation ist eine der häufigsten Eingriffe in der Allgemeinchirurgie. Die vorliegende Arbeit untersucht den Einfluss der Operationstechniken nach Lichtenstein, TAPP und Desarda auf den intra- und postoperativen Verlauf und die Lebensqualität der Patienten. Ziel dieser Arbeit ist es zu hinterfragen, ob sich in der längerfristigen Betrachtung die Empfehlung der aktuellen Leitlinie einen minimalinvasiven Ansatz zu präferieren, aufrechterhalten lässt.

description: In the present paper we discuss properties of a model of a ring wormhole, recently proposed by Gibbons and Volkov. Such a wormhole connects two flat spacetimes which are glued through discs of the radius $a$ bounded by the string with negative angle deficit $-2π$. The presence of the string's matter violating null energy condition makes the wormhole static and traversable. We study gravitational field of static sources in such a spacetime in the weak field approximation. In particular, we discuss how a field of an oblate thin massive shell surrounding one of the wormhole's mouth is modified by its presence. We also obtain a solution of a similar problem when both mouths of the wormhole are located in the same space. This approximate solution if found for the case when the distance $L$ between these mouths is much larger than the radius $a$ of the ring. We demonstrate that the corresponding locally static gravitational field in such a multiply connected space is non-potential. As a result of this, the proper time gap for the clock's synchronization linearly grows with time and closed timelike curves are formed. This process inevitably transforms such a traversable ring wormhole into a time machine. We estimate the time scale of this process.

description: A facile, efficient and eco‐friendly catalytic protocol was developed for the synthesis of medicinally important pyran‐annulated heterocycles via multicomponent reaction (MCR). Cyclocondensation of differently substituted aromatic aldehydes, malononitrile/ethyl cyanoacetate and various β‐dicarbonyl compounds in the presence of Ag3[PMo12O40]⋅nH2O as heterogeneous catalyst, in EtOH–H2O, afforded diverse pyran‐fused chromene analogues. The merits observed for this approach were it being conducted via MCR, using commercially available or easily accessible starting materials in the presence of a green and easily separable heterogeneous and reusable catalyst, and affording high yields of desired products in very short reaction times with high purity in one‐pot fashion, thus providing a superior alternative approach for the synthesis of pyran‐annulated heterocycles.

description: We consider a power system with $N$ transmission lines whose initial loads (i.e., power flows) $L_1, \ldots, L_N$ are independent and identically distributed with $P_L(x)$. The capacity $C_i$ defines the maximum flow allowed on line $i$, and is assumed to be given by $C_i=(1+α)L_i$, with $α>0$. We study the robustness of this power system against random attacks (or, failures) that target a $p$-{\em fraction} of the lines, under a democratic fiber bundle-like model. Namely, when a line fails, the load it was carrying is redistributed equally among the remaining lines. Our contributions are as follows: i) we show analytically that the final breakdown of the system always takes place through a first-order transition at the critical attack size $p^{\star}=1-\frac{E[L]}{\max\{P(L>x)(αx + E[L ~|~ L>x])\}}~~~$; ii) we derive conditions on the distribution $P_L(x)$ for which the first order break down of the system occurs abruptly without any preceding diverging rate of failure; iii) we provide a detailed analysis of the robustness of the system under three specific load distributions: Uniform, Pareto, and Weibull, showing that with the minimum load $L_{\textrm{min}}$ and mean load $E[L]$ fixed, Pareto distribution is the worst (in terms of robustness) among the three, whereas Weibull distribution is the best with shape parameter selected relatively large; iv) we provide numerical results that confirm our mean-field analysis; and v) we show that $p^{\star}$ is maximized when the load distribution is a Dirac delta function centered at $E[L]$, i.e., when all lines carry the same load; we also show that optimal $p^{\star}$ equals $\fracα{α+1}$. This last finding is particularly surprising given that heterogeneity is known to lead to high robustness against random failures in many other systems.

description: Motivation: The majority of variation identified by genome wide association studies falls in non-coding genomic regions and is hypothesized to impact regulatory elements that modulate gene expression. Here we present a statistically rigorous software tool GREGOR (Genomic Regulatory Elements and Gwas Overlap algoRithm) for evaluating enrichment of any set of genetic variants with any set of regulatory features. Using variants from five phenotypes, we describe a data-driven approach to determine the tissue and cell types most relevant to a trait of interest and to identify the subset of regulatory features likely impacted by these variants. Last, we experimentally evaluate six predicted functional variants at six lipid-associated loci and demonstrate significant evidence for allele-specific impact on expression levels. GREGOR systematically evaluates enrichment of genetic variation with the vast collection of regulatory data available to explore novel biological mechanisms of disease and guide us toward the functional variant at trait-associated loci.

description: The positions and velocities of galaxies in the Local Group (LG) measure the gravitational field within it. This is mostly due to the Milky Way (MW) and Andromeda (M31). We constrain their masses using distance and radial velocity (RV) measurements of 32 LG galaxies. To do this, we follow the trajectories of many simulated particles starting on a pure Hubble flow at redshift 9. For each observed galaxy, we obtain a trajectory which today is at the same position. Its final velocity is the model prediction for the velocity of that galaxy. Unlike previous simulations based on spherical symmetry, ours are axisymmetric and include gravity from Centaurus A. We find the total LG mass is ${4.33^{+0.37}_{-0.32}\times{10}^{12}M_\odot}$, with $0.14 \pm 0.07$ of this being in the MW. We approximately account for IC 342, M81, the Great Attractor and the Large Magellanic Cloud. No plausible set of initial conditions yields a good match to the RVs of our sample of LG galaxies. Observed RVs systematically exceed those predicted by the best-fitting $Λ$CDM model, with a typical disagreement of ${45.1^{+7.0}_{-5.7}}$ km/s and a maximum of ${110 \pm 13}$ km/s for DDO 99. Interactions between LG dwarf galaxies can't easily explain this. One possibility is a past close flyby of the MW and M31. This arises in some modified gravity theories but not in $Λ$CDM. Gravitational slingshot encounters of material in the LG with either of these massive fast-moving galaxies could plausibly explain why some non-satellite LG galaxies are moving away from us even faster than a pure Hubble flow.

description: Rydberg atoms are highly excited atoms with intriguing properties. In the framework of quantum electrodynamics, the internal dynamics of a Rydberg atom in front of a surface are investigated in fourth order perturbation theory. For a pair of Rb Rydberg atoms in front of a perfectly conducting surface, a bound state with micrometer bond length, a Rydberg macrodimer, is predicted for a small window of surface distance. This leads to the possibility to use surface properties to actively tune interactions.

description: Summary: A key to understanding RNA function is to uncover its complex 3D structure. Experimental methods used for determining RNA 3D structures are technologically challenging and laborious, which makes the development of computational prediction methods of substantial interest. Previously, we developed the iFoldRNA server that allows accurate prediction of short (<50 nt) tertiary RNA structures starting from primary sequences. Here, we present a new version of the iFoldRNA server that permits the prediction of tertiary structure of RNAs as long as a few hundred nucleotides. This substantial increase in the server capacity is achieved by utilization of experimental information such as base-pairing and hydroxyl-radical probing. We demonstrate a significant benefit provided by integration of experimental data and computational methods.

description: Experiments in the high-luminosity runs at the Large Hadron Collider face the challenges of very large pile-up. Primary techniques to deal with this are based on precise vertex and track reconstruction. Outside tracker acceptances, however, lie regions of interest for many aspects of the LHC physics program. We explore complementary approaches to pile-up treatment and propose a data-driven jet-mixing method which can be used outside tracker acceptances without depending on Monte Carlo generators. The method can be applied to treat correlation observables and take into account, besides the jet transverse momentum pedestal, effects of hard jets from pile-up.

description: Neutron stars might have multipole magnetic fields as implied by recent observations of pulsars. The presence of the quadrupole field might have an effect on the interaction between the disc and the neutron star depending on the location of the inner radius of the disc and the strength of the quadrupole field. For a quadrudipole stellar field, we calculate the toroidal field generated within the disc, the magnetospheric radius and the torque exerted onto the star. Also, we deduce the effect of the rotation of the star on the magnetospheric radius which is relevant even for pure dipole magnetic fields.

Torque Enhancement, Spin Equilibrium, and Jet Power from Disk-Induced Opening of Pulsar Magnetic Fields

description: The interaction of a rotating star's magnetic field with a surrounding plasma disk lies at the heart of many questions posed by neutron stars in X-ray binaries. We consider the opening of stellar magnetic flux due to differential rotation along field lines coupling the star and disk, using a simple model for the disk-opened flux, the torques exerted on the star by the magnetosphere, and the power extracted by the electromagnetic wind. We examine the conditions under which the system enters an equilibrium spin state, in which the accretion torque is instantaneously balanced by the pulsar wind torque alone. For magnetic moments, spin frequencies, and accretion rates relevant to accreting millisecond pulsars, the spin-down torque from this enhanced pulsar wind can be substantially larger than that predicted by existing models of the disk-magnetosphere interaction, and is in principle capable of maintaining spin equilibrium at frequencies less than 1 kHz. We speculate that this mechanism may account for the non-detection of frequency increases during outbursts of SAX J1808.4-3658 and XTE J1814-338, and may be generally responsible for preventing spin-up to sub-millisecond periods. If the pulsar wind is collimated by the surrounding environment, the resulting jet can satisfy the power requirements of the highly relativistic outflows from Cir X-1 and Sco X-1. In this framework, the jet power scales relatively weakly with accretion rate, L_j ~ Mdot^{4/7}, and would be suppressed at high accretion rates only if the stellar magnetic moment is sufficiently low.

China's Impact on Latin American Development: A Comparative Study of Bolivia and Venezuela
Creators: name: Christensen, Steen Fryba
Publisher: name: Journal of China and International Relations
Year: 2016

description: This analysis compares Bolivia's and Venezuela's recent development path and China's impact on it. The two country cases have been chosen due to the fact that they have experienced quite different economic development paths since the international financial crisis in 2008-2009, although they have pursued largely similar economic development strategies and foreign policy strategies. Bolivia has done much better than Venezuela that is now experiencing a chaotic social and economic situation with high levels of inflation and finances out of control. In contrast, Bolivia maintains stable growth figures of between four and five percent and is one of just a small select group of South American commodity exporting countries that is able to pursue counter-cyclical macroeconomic policies. The analysis further argues that China's significance was negligible at the turn of the Century and had become somewhat more significant for Venezuela by 2009, while it was still rather insignificant for Bolivia. Since then, China's significance has grown, particularly in Venezuela that has needed much foreign financing and had been frozen out of international financial markets. However, China has also grown in significance for Bolivia and mostly has had a positive, though, not big impact on its development. In contrast, China's impact on Venezuela has been bigger and mostly positive, but it has not sufficed to end Venezuela’s current development crisis.

description: Summary: In next generation sequencing (NGS)-based genetic studies, researchers typically perform genotype calling first and then apply standard genotype-based methods for association testing. However, such a two-step approach ignores genotype calling uncertainty in the association testing step and may incur power loss and/or inflated type-I error. In the recent literature, a few robust and efficient likelihood based methods including both likelihood ratio test (LRT) and score test have been proposed to carry out association testing without intermediate genotype calling. These methods take genotype calling uncertainty into account by directly incorporating genotype likelihood function (GLF) of NGS data into association analysis. However, existing LRT methods are computationally demanding or do not allow covariate adjustment; while existing score tests are not applicable to markers with low minor allele frequency (MAF). We provide an LRT allowing flexible covariate adjustment, develop a statistically more powerful score test and propose a combination strategy (UNC combo) to leverage the advantages of both tests. We have carried out extensive simulations to evaluate the performance of our proposed LRT and score test. Simulations and real data analysis demonstrate the advantages of our proposed combination strategy: it offers a satisfactory trade-off in terms of computational efficiency, applicability (accommodating both common variants and variants with low MAF) and statistical power, particularly for the analysis of quantitative trait where the power gain can be up to ∼60% when the causal variant is of low frequency (MAF < 0.01).
Venezuela and China: Independency and Dependency in the Context of Interdependent Hegemony
Creators: name: Agustín, Óscar García
Publisher: name: Journal of China and International Relations
Year: 2016

description: In a world order without a sole hegemon, the dialectic relationship between the main global players and emerging powers enables nation-states to strategically favor their national interests as well as mutually beneficial alliances, whilst the multipolar world becomes strengthened. This article draws on this context of 'interdependent hegemony' to explore the existing relationship between Venezuela, as a swing state, and China, as one of the Big Three global powers. Particularly, I focus on Venezuelan efforts to develop, at the domestic and regional level, a counterhegemonic political project against the US and how China is considered a valuable ally to acquire more independence. However, this situation of interdependence can paradoxically lead to a new kind of dependence, in this case on China. To analyze these relations, I propose a conceptual framework consisting of three dimensions: 1) the international positioning towards other Northern and Southern countries and whether the relationship is conceived in terms of conflict or cooperation; 2) the economic model and how it conditions the relationship between countries and whether relationships or dependence are generated; and 3) the development of a political and economic model which can inspire or be followed by other countries. Although China's influence and increasing power in Venezuela is unquestionable in economic terms, the Venezuelan government uses its agreements with China strategically to legitimate its policies, in the name of a South-socialist alternative, and to reaffirm its international positioning.

description: We investigate the linear stability of scalarized black holes (BHs) and neutron stars (NSs) in the Einstein-scalar-Gauss-Bonnet (GB) theories against the odd- and even-parity perturbations including the higher multipole modes. We show that the angular propagation speeds in the even-parity perturbations in the $\ell \to \infty$ limit, with $\ell$ being the angular multipole moments, become imaginary and hence scalarized BH solutions suffer from the gradient instability. We show that such an instability appears irrespective of the structure of the higher-order terms in the GB coupling function and is caused purely due to the existence of the leading quadratic term and the boundary condition that the value of the scalar field vanishes at the spatial infinity.~This indicates that the gradient instability appears at the point in the mass-charge diagram where the scalarized branches bifurcate from the Schwarzschild branch. We also show that scalarized BH solutions realized in a nonlinear scalarization model also suffer from the gradient instability in the even-parity perturbations. Our result also suggests the gradient instability of the exterior solutions of the static and spherically-symmetric scalarized NS solutions induced by the same GB coupling functions.

description: Cerebral cavernous malformation (CCM) involves the homozygous inactivating mutations of one of three genes, ccm1, -2, or -3 resulting in hyperpermeable blood vessels in the brain. The CCM1, -2, and -3 proteins form a complex to organize the signaling networks controlling endothelial cell physiology including actin dynamics, tube formation, and adherens junctions. The common biochemical defect with the loss of CCM1, -2, or -3 is increased RhoA activity leading to the activation of Rho-associated coiled coil-forming kinase (ROCK). Inhibition of the ROCK rescues CCM endothelial cell dysfunction, suggesting that the inhibition of RhoA-ROCK signaling may be a therapeutic strategy to prevent or arrest the progression of the CCM lesions.

description: We consider discrete and integer-valued cellular automata (CA). A particular class of which comprises "Hamiltonian CA" with equations of motion that bear similarities to Hamilton's equations, while they present discrete updating rules. The dynamics is linear, quite similar to unitary evolution described by the Schroedinger equation. This has been essential in our construction of an invertible map between such CA and continuous quantum mechanical models, which incorporate a fundamental discreteness scale. Based on Shannon's sampling theory, it leads, for example, to a one-to-one relation between quantum mechanical and CA conservation laws. The important issue of linearity of the theory is examined here by incorporating higher-order nonlinearities into the underlying action. These produce inconsistent nonlocal (in time) effects when trying to describe continuously such nonlinear CA. Therefore, in the present framework, only linear CA and local quantum mechanical dynamics are compatible.

description: We investigated the pressure dependence of gas flow and field ion intensity of a coaxial ion source operating at room temperature over a wide pressure range, testing various gases and ionisation voltages. Flow conductance measurements taking into account the different gases' viscosity and molecular mass consistently exhibit a generic pattern. Three different flow regimes appear with increasing upstream pressure. Since the coaxial ion source supplies the gas locally, very near the apex of the tip where ionisation occurs, large ionisation currents can be obtained without degrading the propagation conditions of the beam. Compared with field ionisation in a partial pressure chamber, using the coaxial ion source increases the ion current a hundredfold for the same residual low pressure. We also show that the gas flow regime does not impact ionisation yield. Although a fuller characterisation remains to be performed, brightness reaches 3 x 10 11 A/m 2 /sr at 12kV extracting voltage. a) https://www.cinam.univ-mrs.fr/

description: Scattering among electrons generates a distinct contribution to electrical resistivity that follows a quadratic temperature dependence. In strongly-correlated electron systems, the prefactor A of this T$^2$ resistivity scales with the magnitude of the electronic specific heat. Here, we show that one can change the magnitude of A by four orders of magnitude in metallic SrTiO3 by tuning the concentration of the carriers and consequently, the Fermi energy. The T$^2$ behavior persists in the single-band dilute limit despite the absence of two known mechanisms for T$^2$ behavior, distinct electron reservoirs and Umklapp processes. The results highlight the absence of a microscopic theory for momentum decay through electron-electron scattering in different Fermi liquids.

description: Wild product harvesting by forest-dwelling peoples, including hunting, fishing, forest product collection and timber harvesting, is believed to be a major threat to the biodiversity of tropical forests worldwide. Despite this threat, few studies have attempted to quantify these activities across time or across large spatial scales. We use a unique longitudinal household survey (n = 480) to describe changes in these activities over time in 32 indigenous communities from five ethnicities in the northern Ecuadorian Amazon. To provide insight into the drivers of these changes, we also estimate multilevel statistical models of these activities as a function of household and community characteristics. These analyses reveal that participation in hunting, fishing, and forest product collection is high but declining across time and across ethnicities, with no evidence for a parallel decline in resource quality. However, participation in timber harvesting did not significantly decline and there is evidence of a decline in resource quality. Multilevel statistical models additionally reveal that household and community characteristics such as ethnicity, demographic characteristics, wealth, livelihood diversification, access to forest, participation in conservation programs and exposure to external markets are significant predictors of wild product harvesting. These characteristics have changed over time but cannot account for declining participation in resource harvesting. This finding suggests that participation is declining due to changes in the regional-scale social and economic context, including urbanization and the expansion of government infrastructure and services. The lesson for conservationists is that macro-scale social and economic conditions can drive reductions in wild product harvesting even in the absence of successful conservation interventions.

description: In East Africa, Kenya is the most industrially developed country. With the manufacturing sector being an important industry to the Kenyan economy, there is need for fourth industrial revolution technologies such as Internet of things, augmented reality, simulation, additive manufacturing, system integration, cloud computing, autonomous systems, cybersecurity, and big data analytics whose aim is to merge with humans’ physical lives to be fully adopted throughout the supply chain and this is seen through the firm’s performance indicators. The aim of the study was to determine the effects of the fourth industrial revolution on firm’s performance within the food and beverage sector. A review of the literature found that effects of the fourth industrial revolution do not directly impact profitability but increases the productivity of the firm and this results in the manufacturing process being efficient. An exploratory mixed methods study was conducted and data from 95 firms was used for the analysis. Using ordered probit modelling, it was concluded that most of the firms showed a statistically significant effect of adoption of the simulation (i.e., the mirroring of physical world to virtual mode), and additive manufacturing (i.e., 3D printing) to the firm performance variables which are operating income, market share, profitability, return on assets, return on equity and sales growth. The findings offer future research directions by emphasising the need to include other sectors and firms within the manufacturing industry to better understand the impact of fourth industrial revolution.
2010年后中美关系调整 ——基于“制度体系”理论解读 / The Readjustment of China-US Relations After 2010 - Based on The Theory of 'Institutional System'

description: 二战后，国际体系逐渐从“权力体系”进入“制度体系”时代，国际制度成为国际体系建设的核心，大国围绕制度结构中优势地位的争夺变为推动彼此关系变化的主要动因。“制度体系”背景下，国际制度主导国为维护自身主导地位，往往使用“安全杠杆”，在维持国际市场开放性前提下，建立“歧视”崛起国的国际经济制度，推动经济要素向着有利于己方的方向流动，削弱崛起国的物质基础和政策自由度。2010年前后，国际制度结构进入加速调整期，重点是在东亚地区，中国则是主要推动力。国际制度结构的调整威胁了美国原有的主导地位。因此，2010年前后，中美之间的矛盾瞬时尖锐起来。中美此轮博弈的焦点是东亚国际制度主导权，美国的安全战略只是手段，面对美国即将建立的针对中国的“歧视”性国际经济制度安排（TPP），中国需在更大范围内的加大开放，以“共同发展”应对该歧视战略。 After World War II, international order gradually changed from a 'power-centered system' to an 'Institution-based System'. International Institution became the core stone in the construction of the international order. Occupying an advantageous position in the institutional structure became the main factor in driving relational changes between major powers. Against the background of 'institutional system', the dominant countries are inclined to use the 'security lever' as a tool to maintain their dominant position. In order to promote economic factors conducive to their own benefit, these dominant powers set up a series of discriminative international institutions against emerging powers by weakening their material foundation and their room for maneuver in policy-making without destabilizing the liberalization of global market. After 2010, the international order entered into a period of re-adjustment during which East Asia became the pivotal center of attention while China became the main driving force. This situation was seen as a threat to the existing US hegemony. Therefore, before and after 2010 the contradictions between China and the United States were intensifying, and the focus of this round of China-US power struggle aimed to occupy the hegemonic position in shaping the international order in East Asia. Perceiving the US “security strategy” as a means and facing the US-led discriminative international economic order (TPP), China needs to broaden its openness and to use the "common development" strategy to deal with the US discriminative strategy.
