I present first results from an in-progress calculation of BK in quenched approximation using overlap fermions. My particular implementation of the overlap uses a kernel with nearest and next-nearest neighbor interactions and HYP-blocked gauge connections. Matching to the continuum NDR regularization is done perturbatively. I present preliminary results at β = 5.9 and 6.1 (lattice spacings 0.12...

Within a simple mean-field model (self-consistent Hartree approximation) we discuss the possibility of polaron formation on a molecular wire as a mechanism for negative differential resistance (NDR), switching, and/or hysteresis in the I-V characteristic of molecular junctions. This mechanism differs from earlier proposed mechanisms of charging and conformational change. The polaron model captu...

We report stable and reproducible switching and memory effects in self-assembled monolayers (SAMs). We demonstrate realization of negative differential resistance (NDR) and charge storage in electronic devices that utilize single redox-center-contained SAM as the active component; and compare the effects of various redox centers to switching and storage behavior. The devices exhibit electronica...

We present a detailed description of the method and results of our calculation of the kaon B parameter using the Wilson quark action in quenched QCD at β = 5.9 − 6.5. The mixing problem of the ∆s = 2 four-quark operators is solved non-perturbatively with full use of chiral Ward identities. We find BK (NDR, 2GeV) = 0.562(64) in the continuum limit, which agrees with the value obtained with the K...

The kaon B parameter is calculated in quenched lattice QCD with the Wilson quark action. The mixing problem of the ∆s = 2 four-quark operators is solved non-perturbatively with full use of chiral Ward identities, and this method enables us to construct the weak four-quark operators exhibiting good chiral behavior. We find BK(NDR, 2GeV) = 0.562(64) in the continuum limit, which agrees with the v...

Chromatin is structurally involved in the transcriptional regulation of all genes. While the nucleosome positioning at RNA polymerase II (pol II) promoters has been extensively studied, less is known about the chromatin structure at pol III promoters in human cells. We use a high-resolution analysis to show substantial differences in chromatin structure of pol II and pol III promoters, and betw...

Die Programmiersprache Python ist multifunktional. Unter anderem lassen sich mit ihr große Textmengen sprachlich und inhaltlich auswerten. Im Rahmen des Seminars Wissensorganisation 2 im Sommersemester 2022 sollten wir auf Grundlage von einen selbst zusammengestellten Textkorpus in zwei Teilprojekten auswerten klassifizieren. Folgenden werden beide Teilprojekte kurz vorgestellt.
