p-p' Branes in PP-wave Background

open access: yes, 2002
We present several supergravity solutions corresponding to both Dp, as well as Dp-Dp' systems, in NS-NS and R-R PP-wave background originating from AdS_3 times S^3 times R^4.

Determiner spreading as DP-predication [PDF]

open access: yes, 2011
Determiner Spreading (DS) occurs in adjectivally modified nominal phrases comprising more than one definite article, a phenomenon that has received considerable attention and has been extensively described in Greek.

A Simple Nonlinearity-Tailored Probabilistic Shaping Distribution for Square QAM [PDF]

open access: yes, 2017
A new probabilistic shaping distribution that outperforms Maxwell-Boltzmann is studied for the nonlinear fiber channel. Additional gains of 0.1 bit/symbol MI or 0.2 dB SNR for both DP-256QAM and DP-1024QAM are reported after 200 km nonlinear fiber ...

Two-Stage Bagging Pruning for Reducing the Ensemble Size and Improving the Classification Performance [PDF]

open access: yes, 2019
Ensemble methods, such as the traditional bagging algorithm, can usually improve the performance of a single classifier. However, they usually require large storage space as well as relatively time-consuming predictions. Many approaches were developed to

Peptide‐based ligand antagonists block a Vibrio cholerae adhesin

open access: yesFEBS Letters, EarlyView.
The structure of a peptide‐binding domain of the Vibrio cholerae adhesin FrhA was solved by X‐ray crystallography, revealing how the inhibitory peptide AGYTD binds tightly at its Ca2+‐coordinated pocket. Structure‐guided design incorporating D‐amino acids enhanced binding affinity, providing a foundation for developing anti‐adhesion therapeutics ...

Binding in Turkish Nominal Phrases and Phase-Sliding

open access: yesDilbilim Araştırmaları Dergisi, 2019
There are studies within literature which claim that nominal phrases such as DPs also constitute phases in addition to v*Ps and CPs (Chomsky, 2006; Hiraiwa, 2005; Marantz, 2007; Ott, 2008 and Svenious, 2004 among others).

Dielectric-Branes [PDF]

open access: yes, 1999
We extend the usual world-volume action for a Dp-brane to the case of N coincident Dp-branes where the world-volume theory involves a U(N) gauge theory.

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS

open access: yesFEBS Letters, EarlyView.
We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

Virtual characterization via knowledge-enhanced representation learning: from organic conjugated molecules to devices

open access: yesnpj Computational Materials
The rational design of organic functional devices relies on understanding structure-property-performance relationships through multi-scale characterization. However, traditional characterizations are costly and require multidisciplinary expertise.
