Noncentral extensions as anomalies in classical dynamical systems [PDF]

open access: yes, 2002
A two cocycle is associated to any action of a Lie group on a symplectic manifold. This allows to enlarge the concept of anomaly in classical dynamical systems considered by F. Toppan [in J. Nonlinear Math. Phys.

Multi-interior-spike solutions for the Cahn-Hilliard equation with arbitrarily many peaks [PDF]

open access: yes, 2000
We study the Cahn-Hilliard equation in a bounded smooth domain without any symmetry assumptions. We prove that for any fixed positive integer K there exist interior $K$--spike solutions whose peaks have maximal possible distance from the boundary ...

Enzymatic Activity Analysis and Catalytic Essential Residues Identification of Brucella abortus Malate Dehydrogenase

open access: yesThe Scientific World Journal, 2014
Malate dehydrogenase (MDH) plays important metabolic roles in bacteria. In this study, the recombinant MDH protein (His-MDH) of Brucella abortus was purified and its ability to catalyze the conversion of oxaloacetate (OAA) to L-malate (hereon referred to

Development of Strand-Specific Real-Time RT-PCR to Distinguish Viral RNAs during Newcastle Disease Virus Infection

open access: yesThe Scientific World Journal, 2014
Newcastle disease virus (NDV) causes large losses in the global fowl industry. To better understand NDV replication and transcription cycle, quantitative detection methods for distinguishing NDV genomic RNA (gRNA), antigenomic RNA (cRNA), and messenger ...

Strong density for higher order Sobolev spaces into compact manifolds [PDF]

open access: yes, 2015
Given a compact manifold $N^n$, an integer $k \in \mathbb{N}_*$ and an exponent $1 \le p < \infty$, we prove that the class $C^\infty(\overline{Q}^m; N^n)$ of smooth maps on the cube with values into $N^n$ is dense with respect to the strong topology in ...

Out of nothing [PDF]

open access: yes, 2018
Graham Priest proposed an argument for the conclusion that \u2018nothing\u2019 occurs as a singular term and not as a quantifier in a sentence like (1) \u2018The cosmos came into existence out of nothing\u2019.

hnRNPH1 Inhibits Influenza Virus Replication by Binding Viral RNA

open access: yesMicroorganisms
During the life cycle of the influenza virus, viral RNPs (vRNPs) are transported to the nucleus for replication. Given that a large number of progeny viral RNA occupies the nucleus, whether there is any host protein located in the nucleus that recognizes

Observation of the Singly Cabibbo-Suppressed Decay $D^{+}\to\omega\pi^{+}$ and Evidence for $D^{0}\to\omega\pi^{0}$ [PDF]

open access: yes, 2015
Based on 2.93 fb$^{-1}$ $e^+e^-$ collision data taken at center-of-mass energy of 3.773 GeV by the BESIII detector, we report searches for the singly Cabibbo-suppressed decays $D^{+}\to\omega\pi^{+}$ and $D^{0}\to\omega\pi^{0}$. A double tag technique is
