K-S(0) and Lambda Production in Pb-Pb Collisions at root s(NN)=2: 76 TeV

open access: yes, 2013
The ALICE measurement of K^0_S and {\Lambda} production at mid-rapidity in Pb-Pb collisions at sqrt(sNN) = 2.76 TeV is presented. The transverse momentum (pT) spectra are shown for several collision centrality intervals and in the pT range from 0.4 GeV/c

The segregated $\Lambda$-coalescent [PDF]

open access: yesThe Annals of Probability, 2015
We construct an extension of the Lambda-coalescent to a spatial continuum and analyse its behaviour. Like the Lambda-coalescent, the individuals in our model can be separated into (i) a dust component and (ii) large blocks of coalesced individuals. We identify a five phase system, where our phases are defined according to changes in the qualitative ...

CALPHAD‐Guided Prediction and Interpretation of Phase Formation in Ta–Mo–Cr–Ti–Al Refractory High‐Entropy Alloys

open access: yesAdvanced Engineering Materials, EarlyView.
This study designs Ta–Mo–Cr–Ti–Al refractory high‐entropy alloys with a disordered body‐centered‐cubic A2 crystal structure aiming for improved ductility, lower density, and oxidation resistance. Four alloy compositions are identified by thermodynamic calculations.

The representation of oneself in political-narrative discourses: from lambda to ethos

open access: yesSigno y Seña, 2018
In this article we analyze, from a polyphonic and non-referential perspective of enunciation (Ducrot 1984), a set of political-narrative discourses, that is, micronarration where the political speaker talks about himself in the recent past.

On the difference of spectral projections [PDF]

open access: yes, 2015
For a semibounded self-adjoint operator $ T $ and a compact self-adjoint operator $ S $ acting on a complex separable Hilbert space of infinite dimension, we study the difference $ D(\lambda) := E_{(-\infty, \lambda)}(T+S) - E_{(-\infty, \lambda)}(T), \,

Measurements of $J/\psi$ and $\psi(2S)$ decays into $\Lambda \bar{\Lambda}\pi^0$ and $\Lambda \bar{\Lambda}\eta$

open access: yes, 2007
Using 58 million $J/\psi$ and 14 million $\psi(2S)$ events collected by the BESII detector at the BEPC, branching fractions or upper limits for the decays $J/\psi$ and $\psi(2S) \to \Lambda \bar{\Lambda}\pi^0$ and $\Lambda \bar{\Lambda}\eta$ are measured.

Optimized Strategy for Fabricating High‐Aspect‐Ratio Periodic Structures Over Large Areas Using ps‐Direct Laser Interference Patterning

open access: yesAdvanced Engineering Materials, EarlyView.
Picosecond direct laser interference patterning (DLIP) enables precise microstructure fabrication on stainless steel. Using a multiscan approach, high‐aspect‐ratio patterns are achieved. Fluence influences structure growth and homogeneity, with smaller periods yielding better uniformity.

Considerations of Physical Design and Implementation for 5 MHz-100 W LLC Resonant DC-DC Converters

open access: yesActive and Passive Electronic Components, 2016
Recently, high power-density, high power-efficiency, and wide regulation range isolated DC-DC converters have been required. This paper presents considerations of physical design and implementation for wide regulation range MHz-level LLC resonant DC-DC ...

Robustness with respect to exponents for nonautonomous reaction–diffusion equations

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2018
In this work we consider a family of nonautonomous problems with homogeneous Neumann boundary conditions and spatially variable exponents with equation of the form \begin{equation*} \frac{\partial u_{\lambda}}{\partial_t}(t)-\operatorname{div}\left(D(t)

Sol–Gel Synthesis of Ca2.5Ag0.3Sm0.2Co4O9 Semiconducting Materials for Thermoelectric Applications in Aerospace Systems

open access: yesAdvanced Engineering Materials, EarlyView.
Ca2.5Ag0.3Sm0.2Co4O9 semiconductor materials are synthesized and produced in this study using the sol–gel and cold pressing techniques for thermoelectric generator applications. As template samples are added, the Seebeck coefficient and power factor values rise, peaking at 800 °C for Ca2.5Ag0.3Sm0.2Co4O9 at 274.47 μV K−1 and 0.58 mW mK−2, respectively.
