We present new multi-epoch near-infrared (NIR) and optical high-angular images of the V 773 Tau pre-main sequence triple system, a weak-line T Tauri (WTTS) system in which the presence of an evolved, " fossil " protoplanetary disk has been inferred on the basis of a significant infrared (IR) excess. Our images reveal a fourth object bound to the system, V 773 Tau D. While it is much fainter tha...

Recent radio observations have obtained stringent constraints for annihilating dark matter. In this article, we use the continuum spectral data of Large Magellanic Cloud (LMC) to analyze matter annihilation signals. We discovered a slightly positive signal with $1.5\sigma$ statistical significance. The overall best-fit mass is $m_{\rm DM} \approx 90$ GeV, via $b\bar{b}$ channel. also constraine...

Postural stress requires immediate autonomic nervous action to maintain blood pressure. We determined time-domain cardiac baroreflex sensitivity (BRS) and time delay (tau) between systolic blood pressure and interbeat interval variations during stepwise changes in the angle of vertical body axis (alpha). The assumption was that with increasing postural stress, BRS becomes attenuated, accompanie...

Time-resolved Fourier transform infrared (FTIR) difference spectra of the halorhodopsin (hR) photocycle have been collected from 3 micros to 100 ms in saturating concentrations of KCl or KBr. Kinetic analysis of these data revealed two decay processes, with time constants of tau(1) approximately 150 micros and tau(2) approximately 16 ms in the presence of either halide, with tau(2) describing t...

The existing tau-selection strategy, which was designed for explicit tau-leaping, is here modified to apply to implicit tau-leaping, allowing for longer steps when the system is stiff. Further, an adaptive strategy is proposed that identifies stiffness and automatically chooses between the explicit and the (new) implicit tau-selection methods to achieve better efficiency. Numerical testing demo...

Let $A$ be a Banach ternary algebra over a scalar field $Bbb R$ or $Bbb C$ and $X$ be a ternary Banach $A$--module. Let $sigma,tau$ and $xi$ be linear mappings on $A$, a linear mapping $D:(A,[~]_A)to (X,[~]_X)$ is called a Lie ternary $(sigma,tau,xi)$--derivation, if $$D([a,b,c])=[[D(a)bc]_X]_{(sigma,tau,xi)}-[[D(c)ba]_X]_{(sigma,tau,xi)}$$ for all $a,b,cin A$, where $[abc]_{(sigma,tau,xi)}=ata...
