On the validity of the Franck-Condon principle in the optical spectroscopy: optical conductivity of the Fr\"{o}hlich polaron [PDF]

open access: yes, 2006
The optical absorption of the Fr\"{o}hlich polaron model is obtained by an approximation-free Diagrammatic Monte Carlo method and compared with two new approximate approaches that treat lattice relaxation effects in different ways.

Mitochondrial fission promotes self-renewal and tumorigenic potential in prostate cancer

open access: yesMolecular & Cellular Oncology, 2019
The emergence of therapy-resistant cancer stem cells (CSCs) limit the efficacy of prostate cancer treatment. Using genetic knockdown and chemical inhibitors, we demonstrate the critical role of Bromodomain Containing 4 (BRD4) in promoting mitochondrial ...

Dynamic Programming Ring for Point Target Detection

open access: yesApplied Sciences, 2022
To improve the detection efficiency of a long-distance dim point target based on dynamic programming (DP), this paper proposes a multi-frame target detection algorithm based on a merit function filtering DP ring (MFF-DPR).

Milk from forage on organic dairy farms [PDF]

open access: yes, 2013
Milk from forage (MFF) has been used as an indicator of dairy enterprise performance since the 1970s. There is considerable evidence associating MFF with good economic performance. ORC researcher Katharine Leach and intern Gaëlle Feur have been looking

Statistical analysis of factor models of high dimension

open access: yes, 2012
This paper considers the maximum likelihood estimation of factor models of high dimension, where the number of variables (N) is comparable with or even greater than the number of observations (T). An inferential theory is developed. We establish not only

Katalysatoraktivierung als Schlüsselfaktor in Kreuzkupplungen: Raumtemperatur‐Kupplungen schwacher Nukleophile ermöglicht durch [Pd(1‐MeNAP)TFA]2 Präkatalysatoren

open access: yesAngewandte Chemie, EarlyView.
Bei vielen Pd‐katalysierten Kreuzkupplungen hat sich gezeigt, dass die Katalysatorleistung durch dessen Aktivierung begrenzt wird. Methylnaphthyl (MeNAP)‐Palladiumtrifluoracetat‐Dimere werden als leicht zu lagernde und handhabende Präkatalysatoren vorgestellt, die sich unter Reaktionsbedingungen schnell aktivieren, selbst wenn nur schwach ...

Unlocking Catalyst Activation as a Critical Bottleneck in Cross‐Coupling Reactions: Room‐Temperature Couplings of Weak Nucleophiles Enabled by [Pd(1‐MeNAP)TFA]2 Precatalysts

open access: yesAngewandte Chemie International Edition, EarlyView.
In many Pd‐catalyzed cross‐couplings, catalyst performance has been found to be limited by catalyst activation. Methylnaphthyl (MeNAP) palladium trifluoroacetate dimers are presented as easy‐to‐store and easy‐to‐handle precursors, which rapidly activate under reaction conditions, even when only weakly coordinating, non‐reducing nucleophiles are present.
