Life Science Alliance, 2022 In Drosophila photoreceptors, PI(4,5)P 2 synthesis during PLC signalling is regulated by PIP5K and septins. Phosphatidylinositol 4,5-bisphosphate [PI(4,5)P 2 ] hydrolysis by phospholipase C (PLC) is a conserved mechanism of signalling.

Search for the Decay $\tau^- \rightarrow 3\pi^- 2\pi^+2\pi^0 \nu_\tau$ [PDF]
, 2006 A search for the decay of the {tau} lepton to five charged and two neutral pions is performed using data collected by the BABAR detector at the PEP-II asymmetric-energy e{sup +}e{sup -} collider. The analysis uses 232 fb{sup -1} of data at center-of-mass energies on or near the {Upsilon}(4S) resonance.

Finite-time blowup for a complex Ginzburg-Landau equation [PDF]
, 2012 We prove that negative energy solutions of the complex Ginzburg-Landau equation $e^{-i\theta} u_t = \Delta u+ |u|^{\alpha} u$ blow up in finite time, where \alpha >0 and \pi ...

Improvement in the irrationality measures of $\pi $ and $\pi ^2 $
Proceedings of the Japan Academy, Series A, Mathematical Sciences, 1992 The paper deals with irrationality measures for the numbers \(\pi^ 2\) and \(\pi/\sqrt 3\), which is less than 6,3489 and 4,6016 respectively. The linear independence measure of the numbers 1, \(\pi\) and \(\log 2\) is less than 7,0161. The proofs can be found in other works of the author.

Instability of a Landau Fermi liquid as the Mott insulator is approached
, 1998 We examine a two-dimensional Fermi liquid with a Fermi surface which touches the Umklapp surface first at the 4 points $(\pm \pi/2, \pm \pi/2)$ as the electron density is increased. Umklapp processes at the 4 patches near $(\pm \pi/2, \pm\pi/2)$ lead the

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Oral mucositis is a common and debilitating side effect of childhood cancer and stem cell transplant treatments. It affects the quality of life of children and young people (CYP) and places a strain on services. Photobiomodulation is recommended for oral mucositis prevention in international guidance but is poorly implemented in UK ...

Global parameterization of $$\pi \pi $$ ππ scattering up to 2 $${\mathrm {\,GeV}}$$ GeV
European Physical Journal C: Particles and Fields, 2019 We provide global parameterizations of $$\pi \pi \rightarrow \pi \pi $$ ππ→ππ scattering S0 and P partial waves up to roughly 2 GeV for phenomenological use.

On a Pólya’s inequality for planar convex sets
Comptes Rendus. Mathématique, 2022 In this short note, we prove that for every bounded, planar and convex set $\Omega $, one has \[ \frac{\lambda _1(\Omega )T(\Omega )}{|\Omega |}\le \frac{\pi ^2}{12}\cdot \left(1+\sqrt{\pi }\frac{r(\Omega )}{\sqrt{|\Omega |}}\right)^2, \] where $\lambda ...

Magnetism in parent Fe-chalcogenides: quantum fluctuations select a plaquette order
, 2012 We analyze magnetic order in iron-chalcogenide Fe$_{1+y}$Te -- the parent compound of high-temperature superconductor Fe$_{1+y}$Te$_{1-x}$Se$_x$. Neutron scattering experiments show that magnetic order in this material contains components with momentum ...
