Conjugation Systems of IncT Plasmids [PDF]

open access: yesMicrobiology, 1985
Four IncT plasmids were compared for various characters, in particular pilus synthesis and function at different temperatures. The prototype Rts1 differed in some respects from the others (R402, R394, pIN25). At 37 degrees C, the supposedly temperature-sensitive conjugation systems of the plasmids could still function efficiently on a surface, but not ...

Benefit of a Short Chain Peptide as a Targeting Ligand of Nanocarriers for a Brain-Driven Purpose

open access: yesPharmaceutics, 2021
Treatment of glioma remains a critical challenge worldwide, since the therapeutic effect is greatly hindered by poor transportation across the blood brain barrier (BBB) and low penetration into tumor cells.

The prokaryotic ubiquitin-like protein presents poor cleavage sites for proteasomal degradation

open access: yesCell Reports, 2021
Summary: In an event reminiscent of eukaryotic ubiquitination, the bacterial prokaryotic ubiquitin-like protein (Pup)-proteasome system (PPS) marks target proteins for proteasomal degradation by covalently attaching Pup, the bacterial tagging molecule ...

The quantum-classical transition in thermally seeded parametric downconversion [PDF]

open access: yes, 2008
We address the pair of conjugated field modes obtained from parametric-downconversion as a convenient system to analyze the quantum-classical transition in the continuous variable regime.

Direct test of time-reversal symmetry in the entangled neutral kaon system at a $\phi$-factory [PDF]

open access: yes, 2012
We present a novel method to perform a direct T (time reversal) symmetry test in the neutral kaon system, independent of any CP and/or CPT symmetry tests.

Commutativity of systems with their feedback conjugates [PDF]

open access: yesTransactions of the Institute of Measurement and Control, 2018
After introducing commutativity concept and summarizing the relevant literature, this work is focused on the commutativity of feedback conjugates. It is already known that a linear time-varying differential system describing a single input-single output dynamical system is always commutative with its constant gain feedback pairs.

2-{3,5-Bis-[5-(3,4-didodecyloxyphenyl)thien-2-yl]phenyl}-5-(3,4-didodecyloxyphenyl)thiophene

open access: yesMolbank, 2021
Star-shaped compounds are widely recognized as emerging materials for optical and electrical applications and as scaffolds of discotic liquid crystal. While the C3-symmetrical tri(phenylthienyl)benzene is the core for several electroopotical materials ...

Skokie, the ACLU and the Endurance of Democratic Theory [PDF]

open access: yes, 1979
ZnO nanorods (NRs) with high surface area to volume ratio and biocompatibility is used as an efficient photosensitizer carrier system and at the same time providing intrinsic white light needed to achieve cancer cell necrosis.

Conjugate Gradient Methods for Toeplitz Systems [PDF]

open access: yesSIAM Review, 1996
The use of preconditioned conjugate gradient methods to solve linear systems of equations with Toeplitz matrices is discussed. Using this iterative method, the complexity is reduced from \(O(n\log^2n)\) operations for fast direct Toeplitz solvers to \(O(n \log n)\).
