We introduce general q-deformed multiple polylogarithms which even in the dilogarithm case differ slightly from the deformation usually discussed in the literature. The merit of the deformation as suggested, here, is that q-deformed multiple polylogarithms define an algebra, then (as in the undeformed case). For the special case of qdeformed multiple ζ-values, we show that there exists even a n...

Abstract The feasibility of using an external beam microprobe facility to explore the biological effects generated by proton irradiation in cultured cells is demonstrated. An in-air set-up was developed that allows energy tuning and enables estimating flux dose deposition cells. A pilot study on effect boron-rich metallacarboranes as radiosensitizers towards human glioblastoma carried out. This...

In this article, we introduce Brownian motion on α-stable looptrees using resistance techniques, where α∈(1,2). We prove an invariance principle characterising it as the scaling limit of random walks discrete looptrees, and precise local global bounds its heat kernel. also conduct a detailed investigation volume growth properties stable show that kernel fluctuations are locally log-logarithmic,...

A semigroup S is called left ample if it can be embedded in the symmetric inverse IX of partial bijections a non-empty set X such that image closed under unary operation α → αα⁻¹, where α⁻¹ IX. Right semigroups are defined dually. both and right ample. monoid (left, right) as semigroup. We observe dominion an subsemigroup coincides with generated by it. then determine dominions certain submonoi...

در آنزیم α -آمیلاز (baa)b. amyloliquefaciens ، رزیدیوهای 185 – 177 (ناحیه i یا لوپ) سازندة بخشی از محفظة (cage) مسئول اتصال به کلسیم هستند. لوپ موجود در baa دارای دو رزیدیو بیشتر از همتای ترموفیل خود یعنی α -آمیلاز (bla) b. licheniformis می باشد و رزیدیوی arg176 موجود در این بخش با glu126 از ناحیة ii (رزیدیوهای 131 – 118) ایجاد یک پل نمکی می کند که این ارتباط در آنزیم bla به واسطة جایگزینی های ...

OBJECTIVES Alpha thalassaemia is wide spread in Malaysia and is a public health problem. This study aimed to describe the carrier frequencies of α‒thalassaemia and its distribution among major ethnic groups in three states of Malaysia. METHODS Educational forums were organised and study was explained to students from three schools. Students were invited to take part in the screening with pare...

We show that the Sudakov factor from the resummation of double logarithms ln(s/k T ) contained in the distribution functions is responsible for the kT smearing mechanism employed in the next-to-leading-order QCD (αα 2 s) calculations of direct photon production. s is the center-of-mass energy, and kT the transverse momentum carried by a parton in a colliding hadron. This factor exhibits the app...
