2022-05-20ZeitschriftenartikelA 3D gene expression atlas of the floral meristem based on spatial reconstruction of single nucleus RNA sequencing data Cellular heterogeneity in growth and differentiation results in organ patterning. Single-cell transcriptomics allows characterization of gene expression heterogeneity in developing organs at unprecedented resolution. ...

2022-10-27ZeitschriftenartikelA 5′ UTR Mutation Contributes to Down-Regulation of Bbs7 in the Berlin Fat Mouse The Bardet–Biedl Syndrome 7 (Bbs7) gene was identified as the most likely candidate gene causing juvenile obesity in the Berlin Fat Mouse Inbred (BFMI) line. Bbs7 expression is significantly lower in the brain, adipose ...

2021-11-26ZeitschriftenartikelA blind spot in mental healthcare? Psychotherapists lack education and expertise for the support of adults on the autism spectrum Most adults on the autism spectrum have co-occurring mental health conditions, creating a high demand for mental health services – including psychotherapy – in autistic adults. However, autistic adults have difficulties ...

2009-10-21BuchA blocking and regularization approach to high dimensional realized covariance estimation We introduce a regularization and blocking estimator for well-conditioned high-dimensional daily covariances using high-frequency data. Using the Barndorff-Nielsen, Hansen, Lunde, and Shephard (2008a) kernel estimator, we ...

2020-11-19ZeitschriftenartikelA Boothby–Wang Theorem for Besse Contact Manifolds A Reeb flow on a contact manifold is called Besse if all its orbits are periodic, possibly with different periods. We characterize contact manifolds whose Reeb flows are Besse as principal S1\documentclass[12pt]{minimal} ...

2007-06-03BuchA Branch-and-Bound Method for Multistage Stochastic Integer Programs with Risk Objectives We identify multistage stochastic integer programs with risk objectives where the related wait-and-see problems enjoy similar separability as in the risk neutral case. For models belonging to this classwe present a solution ...

2004-02-21BuchA branch-and-cut algorithm for the stochastic uncapacitated lot-sizing problem This paper addresses a multi-stage stochastic integer programming formulation of the uncapacitated lot-sizing problem under uncertainty. We show that the classical $(\mathcal{l}, S)$ inequalities for the deterministic ...

2006-10-27BuchA branch-and-cut algorithm for two-stage stochastic mixed-binary programs with continuous first-stage variables This paper presents a branch-and-cut method for two-stage stochastic mixed-integer programming (SMIP) problems with continuous first-stage variables. This method is derived based on disjunctive decomposition(D2) for SMIP, ...

2002-10-24BuchA branch-and-price algorithm for multi-stage stochastic integer programming with application to stochastic batch-sizing problems In this paper we present a branch-and-price method to solve special structured multi-stage stochastic integer programming problems. We validate our method on two different versions of a multi-stage stochastic batch-sizing ...

2005-01-10BuchA Branch-Reduce-Cut Algorithm for the Global Optimization of Probabilistically Constrained Linear Programs We consider probabilistic constrained linear programs with general distributions for the uncertain parameters. These problems generally involve non-convex feasible sets. We develop a branch and bound algorithm that searches ...

2008-12-18BuchA Brand Specific Investigation of International Cost Shock Threats on Price and Margin with a Manufacturer-Wholesaler-Retailer Model In times of increasing oil prices and a weak dollar, European companies that focus their business on the US market may find themselves in a weak position. While many businesses can hedge this kind of risk by relocating ...
