Dyck paths are classical Catalan objects. The peak distribution of Dyck paths is an important topic of combinatorics, and further the representation of symmetric groups.
Through utilizing water flow monitoring, rock scratching, soil wood piles and radionuclide 137Cs tracing in the Longhe karst ecological experimental site (hereinafter referred to“Longhe site”), Pinggu...
Background: Infant body mass index (BMI) peak characteristics and early childhood BMI are emerging markers of future obesity and cardiometabolic disease risk, but little is known about their maternal ...
The scaling law of the seismic spectrum experimentally calculated at Mt. Vesuvius and Campi Flegrei is used to constrain the estimate of the maximum expected peak acceleration of ground motion.
Electron content statistics offers important information for planning and operation of various application systems that make use of the transionospheric propagation of radio signals. Electron content...
NEW RESULTS ON THE PEAK ALGEBRA     Solomon’s descent algebra  peak algebra  signed permutation       font style='font-size:12px;'> 2015/8/14
The peak algebra Pn is a unital subalgebra of the symmetric group algebra, linearly spanned by sums of permutations with a common set of peaks. By exploiting the combinatorics of sparse subsets of [...
THE PEAK ALGEBRA AND THE DESCENT ALGEBRAS OF TYPES B AND D     peak algebra  signed permutations  Coxeter groups       font style='font-size:12px;'> 2015/8/14
We show the existence of a unital subalgebra Pn of the symmetric group algebra linearly spanned by sums of permutations with a common peak set, which we call the peak algebra. We show that Pn is the...
Comparison of peak and RMS gains for discrete-time systems     Discrete time system  the peak  more income  signal  function       font style='font-size:12px;'> 2015/8/13
A convolution system can have a frequency response which is small for all frequencies, yet still greatly amplify the peaks of signals passing through it. For finite-dimensional systems, the authors es...
Based on the bounds in the paper by Boyd and Doyle (Comparison of peak and RMS gains for discrete-time systems, Systems and Control Letters, 9:1-6), we present simple upper and lower bounds for the el...
Pre-peak Ram Pressure Stripping in the Virgo Cluster Spiral Galaxy NGC 4501     NGC 4501  interactions       font style='font-size:12px;'> 2014/12/23
VIVA Hi observations of the Virgo spiral galaxy NGC 4501 are presented. The Hi disk is sharply truncated to the southwest, well within the stellar disk. A region of low surface-density gas, which is m...
Abstract: The production histories of seventeen raw materials are analyzed with the logistic model. Although many of these resources have exhibited logistic behavior in the past, they now show exponen...
Can transport peak explain the low-mass enhancement of dileptons at RHIC?     dileptons at RHIC       font style='font-size:12px;'> 2011/7/20
We propose a novel relation between the low-mass enhancement of dielectrons observed at PHENIX and transport coefficients of QGP such as the charge diffusion constant $D$ and the relaxation time $\tau...
We simulate the central reactions of nearly symmetric, and asymmetric systems, for the energies at which the maximum production of IMFs occurs (E$_{c.m.}^{peak}$).This study is carried out by using ha...
A long-term study, conducted from February 2005 to July 2008, involving chemical composition and optical properties of ambient aerosols from a high-altitude site (Manora Peak: 29.4° N, 79.5° E, ~1950 ...
Hydrological frequency analyses are usually focused on flood peaks. Flood volumes and durations have not been studied as extensively, although there are many practical situations, such as when designi...
