The Fight for the Middle: Upgrading, Competition, and Industrial Development in China

When China acceded to WTO in 2001, there were fears that Chinese firms would lose market share in key sectors to foreign-invested enterprises (FIEs). Although aggregate data often indicate a shift in favour of FIEs, indigenous firms in many cases have slowly increased market share and deepened their technical capabilities. Through an analysis of aggregate data and three sectors, we show how the dynamics of competition between Chinese and FIEs in China's domestic market enhance the upgrading prospects for Chinese firms. China represents a new model of development in several important respects: industrial upgrading efforts are often domestically-driven, within this domestic market there is intense competition between both domestic and foreign firms, and this competition is driving and stimulating the upgrading efforts of domestic firms.China, industrialization, FDI, upgrading, value-chains, emerging markets, automotive

Interpreting the Atmospheric Neutrino Anomaly

We suggest that the atmospheric neutrino anomaly observed in the Super-Kamiokande (and other) experiments results from the combined effects of muon-neutrino to tau-neutrino oscillations with a Delta m^2 value of approximately 0.4 eV^2 and oscillations between muon neutrinos and electron neutrinos (and vice-versa) with 0.0001 < Delta m^2 < 0.001 eV^2. With an appropriate choice of a three-neutrino mixing matrix, such a hypothesis is consistent with essentially all neutrino observations.Comment: 12 pages, 2 eps figures, Latex2e, elsart style, submitted to Physics Letters B --REV2-- Updated figure 1 and added figure 2: Super-K single R dat

Mennyire jártasak a pedagógusok az esélyegyenlőség pedagógiájában? Esélyegyenlőségi intézkedések és az esélyegyenlőség pedagógiájának ismerete és gyakorlata egy közoktatási intézményekben végzett pilot kutatás alapján

Az oktatási esélyegyenlőség és méltányosság elve és megvalósítási lehetősége a legutóbbi két évtizedben egyre felerősödő diskurzusként jelennek meg az oktatáspolitikában. Az oktatáspolitikai intézkedések azonban meglepően kevéssé alapoznak társadalomtudományi ismeretekre. Az itt bemutatott vizsgálat eredményei alátámasztani látszanak azt a megállapítást, hogy az esélyegyenlőtlenség és diszkrimináció jelensége nem úgy értelmezett az alkalmazott pedagógiában, mint a társadalom egészében észlelhető probléma iskolai leképeződése

Circumbinary discs: Numerical and physical behaviour

We study the evolution of circumbinary disks under the gravitational influence of the binary using two-dimensional hydrodynamical simulations to investigate the impact of disk and binary parameters on the dynamical aspects of the disk. To distinguish between physical and numerical effects we apply three hydrodynamical codes. First we analyse in detail numerical issues concerning the conditions at the boundaries and grid resolution. We then perform a series of simulations with different binary (eccentricity, mass ratio) and disk parameters (viscosity, aspect ratio) starting from a reference model with Kepler-16 parameters. Concerning the numerical aspects we find that the inner grid radius must be of the order of the binary semi-major axis, with free outflow conditions applied such that mass can flow onto the central binary. A closed inner boundary leads to unstable evolutions. We find that the inner disk turns eccentric and precesses for all investigated physical parameters. The precession rate is slow with periods ($T_\mathrm{prec}$) starting at around 500 binary orbits ($T_\mathrm{bin}$) for high viscosity and large $H/R$ where the inner hole is smaller and more circular. Reducing $\alpha$ and $H/R$ increases the gap size and $T_\mathrm{prec}$ reaches 2500 $T_\mathrm{bin}$. For varying binary mass ratios $q_\mathrm{bin}$ the gap size remains constant whereas $T_\mathrm{prec}$ decreases for increasing $q_\mathrm{bin}$. For varying binary eccentricities $e_\mathrm{bin}$ we find two separate branches in the gap size and eccentricity diagram. The bifurcation occurs at around $e_\mathrm{crit} \approx 0.18$ where the gap is smallest with the shortest $T_\mathrm{prec}$. For $e_\mathrm{bin}$ smaller and larger than $e_\mathrm{crit}$ the gap size and $T_\mathrm{prec}$ increase. Circular binaries create the most eccentric disks.Comment: 20 pages, 25 figures, published in A&A, language edited versio

Peeling property and asymptotic symmetries with a cosmological constant

This paper establishes two things in an asymptotically (anti-)de Sitter spacetime, by direct computations in the physical spacetime (i.e. with no involvement of spacetime compactification): (1) The peeling property of the Weyl spinor is guaranteed. In the case where there are Maxwell fields present, the peeling properties of both Weyl and Maxwell spinors similarly hold, if the leading order term of the spin coefficient $\rho$ when expanded as inverse powers of $r$ (where $r$ is the usual spherical radial coordinate, and $r\rightarrow\infty$ is null infinity, $\mathcal{I}$) has coefficient $-1$. (2) In the absence of gravitational radiation (a conformally flat $\mathcal{I}$), the group of asymptotic symmetries is trivial, with no room for supertranslations.Comment: 28 pages, two recent relevant references are included.

Why digital medicine depends on interoperability

Digital data are anticipated to transform medicine. However, most of today's medical data lack interoperability: hidden in isolated databases, incompatible systems and proprietary software, the data are difficult to exchange, analyze, and interpret. This slows down medical progress, as technologies that rely on these data - artificial intelligence, big data or mobile applications - cannot be used to their full potential. In this article, we argue that interoperability is a prerequisite for the digital innovations envisioned for future medicine. We focus on four areas where interoperable data and IT systems are particularly important: (1) artificial intelligence and big data; (2) medical communication; (3) research; and (4) international cooperation. We discuss how interoperability can facilitate digital transformation in these areas to improve the health and well-being of patients worldwide

Three-Flavour Neutrino-Mixing Implications of the LSND Result

The LSND result is shown to fit into a minimal three-flavour neutrino-mixing scenario capable of describing all known experimental facts provided the large Delta M^2 = m_3^2 - m_2^2 \sim m_3^2 - m_1^2 lies in the range 2.5 x 10^{-1} < Delta M^2 < 3.0 eV^2. In this range the value of P_{\mu\tau} is expected to be about 5% or larger.Comment: 10 pages, 2 eps figures, LaTeX 2.09, revised for Physics Letters
