Deformations of Calabi-Yau manifolds in Fano toric varieties

2020

In this article, we investigate deformations of a Calabi-Yau manifold $Z$ in a toric variety $F$, possibly not smooth. In particular, we prove that the forgetful morphism from the Hilbert functor $H^F_Z$ of infinitesimal deformations of $Z$ in $F$ to the functor of infinitesimal deformations of $Z$ is smooth. This implies the smoothness of $H^F_Z $ at the corresponding point in the Hilbert scheme. Moreover, we give some examples and include some computations on the Hodge numbers of Calabi-Yau manifolds in Fano toric varieties.

Canonical Brownian Motion on the Diffeomorphism Group of the Circle

2002

AbstractFor infinitesimal data given on the group of diffeomorphism of the circle with respect to the metric H3/2, the associated Brownian motion has been constructed by Malliavin (C.R. Acad. Sci. Parist.329 (1999), 325–329). In this work, we shall give another approach and prove the invariance of heat measures under the adjoint action of S1.

A geometrical constructive approach to infinitesimal analysis: epistemological potential and boundaries of tractional motion

2014

Recent foundational approaches to Infinitesimal Analysis are essentially algebraic or computational, whereas the first approaches to such problems were geometrical. From this perspective, we may recall the seventeenth-century investigations of the “inverse tangent problem.” Suggested solutions to this problem involved certain machines, intended as both theoretical and actual instruments, which could construct transcendental curves through so-called tractional motion. The main idea of this work is to further develop tractional motion to investigate if and how, at a very first analysis, these ideal machines (like the ancient straightedge and compass) can constitute the basis of a purely geome…

A C0-Semigroup of Ulam Unstable Operators

2020

The Ulam stability of the composition of two Ulam stable operators has been investigated by several authors. Composition of operators is a key concept when speaking about C0-semigroups. Examples of C0-semigroups formed with Ulam stable operators are known. In this paper, we construct a C0-semigroup (Rt)t&ge

Toward a Quality Guide to Facilitate the Transference of Analytical Methods from Research to Testing Laboratories: A Case Study

2009

Abstract At present, there is no single viewpoint that defines QA strategies in analytical chemistry. On the other hand, there are no unique protocols defining a set of analytical tasks and decision criteria to be performed during the method development phase (e.g., by a single research laboratory) in order to facilitate the transference to the testing laboratories intending to adapt, validate, and routinely use this method. This study proposes general criteria, a priori valid for any developed method, recommended as a provisional quality guide containing the minimum internal tasks necessary to publish new analytical method results. As an application, the selection of some basic internal qu…

Next-to-next-to-leading order N -jettiness soft function for one massive colored particle production at hadron colliders

2017

The $N$-jettiness subtraction has proven to be an efficient method to perform differential QCD next-to-next-to-leading order (NNLO) calculations in the last few years. One important ingredient of this method is the NNLO soft function. We calculate this soft function for one massive colored particle production at hadron colliders. We select the color octet and color triplet cases to present the final results. We also discuss its application in NLO and NNLO differential calculations.

Bioloģiskās terapijas ietekme uz medikamentozā pulmonīta risku limfomas pacientiem

2019

Problēmas būtība. Medikamentozais pneimonīts limfomas pacientiem, ir reta, taču nopietna komplikācija ar augstu letalitātes risku. Vairākos pētījumos ir konstatēts, ka monoklonālas antivielas Rituksimaba pievienošana ķīmijterapijai pacientiem ar limfomas diagnozi ir saistīta ar lielāku risku medikamentozā pneimonīta attīstībai. Pētījuma mērķis. Pētījuma galvenais mērķis bija pārbaudīt hipotēzi, ka pastāv saistība starp monoklonālas antivielas Rituksimaba saņemšanu un lielāku risku uz medikamentozā pneimonīta attīstību pacientiem ar limfomas diagnozi.Pētījumā ir veikts 2 pacientu grupu salīdzinājums (limfomas pacienti, kas saņem ķīmijterapiju ar vai bez Rituksimaba), papildus izvērtējot slim…
