Abstract We consider the inverse problem of determining fragmentation rate from noisy measurements in growth-fragmentation equation. use Fourier transform theory on locally compact groups to treat this for general probabilities. develop a regularization method based spectral filtering, which allows us deal with weighted <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" ...

in order to analyse the effective factors contributing to land fragmentation, required data ‎were collected by questionnaire from 151 farmers who were selected through a stratified random ‎sampling design from 12 villages of ramjerd yek subdistrict of marvdasht country. factor analysis ‎was used to identity explanatory factors of land fragmentation. the variables of natural-farming, ‎socio-cult...

The aim of this report has been evaluating protamine content and DNA integrity of two patients with globozoospermia undergoing Intra Cytoplasmic Sperm Injection (ICSI). Semen analysis was carried out according to WHO criteria. Protamine deficiency and DNA fragmentation was assessed using Chromomycin A3 and sperm chromatin dispersion assay respectively. ICSI and chemical activation were carried ...

We present the principles of the measurement of the quark transversity distributions in semi-inclusive deep inelastic electron scattering, which form the basis of HELP and one of the ELFE proposals. A string model for Collins-type asymmetry in polarized quark fragmentation function is proposed. A possible role of the Collins effect in the single spin asymmetries observed by experiment E 704 at ...

Two related issues are discussed, which might be easily explored by present and future COMPASS experiments. The first one deals with the new world of transversity, the fundamental polarized parton distribution so far totally unknown. The second issue concerns Λ production in polarized semi-inclusive processes, with a measurement of the Λ polarization, which might give novel information on distr...

In this paper we analyze deep inelastic one-particle inclusive processes for the case of spin-one targets or for the case of spin-one produced hadrons, such as r mesons. This allows the measurement of new distribution and fragmentation functions not available in the spin-half case, and provides new ways to probe functions otherwise difficult to measure. We will analyze only contributions leadin...

• Charged Multiplicities in DIS and diffractive DIS (DDIS). The use of W and Ecurrent and a unified approach to DIS and DDIS. • Inclusive photoproduction of non-strange mesons. Universal rate curve as a function of (pT +m). • Strange Particle Production and polarisation, looked at as a function of pT , η,Q , x. • Charm fragmentation.

Euphorbia ebracteolata Hayata (E. ebracteolata) is a Chinese herbal medicine used for the treatment of tumor diseases. An ultra-performance liquid chromatography/quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF/MS) based chemical profiling approach was established for the rapid separation and characterization on phloroglucinol derivatives and diterpenes in E. ebracteolata. Three phlorogl...
