considering the importance of of muallaqat in arabic literature, as well as its importance in the various sciences of language and literature, grammatical and contain many of the jahelliah words so many of commentators paid attention to them. one of those topics that attract attention and its worthy of research and investigation are etymology and phonetic issues. in the present study, it is int...
We develop a method to accurately and efficiently determine the vibrational free energy as a function of temperature and volume for substitutional alloys from first principles. Taking Ti_{1-x}Al_{x}N alloy as a model system, we calculate the isostructural phase diagram by finding the global minimum of the free energy corresponding to the true equilibrium state of the system. We demonstrate that...

Two species of Digenea were recorded for the first time in South America and in new hosts: Acanthostomum spiniceps (Looss, 1896) (Cryptogonimidae) was reported from Astroscopus sexspinosus (Steindachner, 1877) (Uranoscopidae) and Diplomonorchis sphaerovarium Nahhas & Cable, 1964 (Monorchiidae) from Ophichthus gomesi (Castelnau, 1855) (Ophichthidae). From the latter, Heliconema heliconema Travas...
One implication of the changing demo_ graphic composition of the Unltea States population is that the number of older workers wil l increase dramatically in com_ ing years in both absolute and relative terms. Particularly in l ight of the virtual climination of mandatory retirement ages in the United States, questions wil l ln_ cvitably arise regarding the productivity of older workers. Althoug...

We report a stable double optical spring effect in an optical cavity pumped with a single optical field that arises as a result of birefringence. One end of the cavity is formed by a multilayer Al_{0.92}Ga_{0.08}As/GaAs stack supported by a microfabricated cantilever with a natural mode frequency of 274 Hz. The optical spring shifts the resonance to 21 kHz, corresponding to a suppression of low...
We analyze the low-energy physics of nearly ferromagnetic metals in two spatial dimensions using the functional renormalization group technique. We find a new low-energy fixed point, at which the fermionic (electronlike) excitations are non-Fermi-liquid (z_{f}=13/10) and the magnetic fluctuations exhibit an anomalous Landau damping whose rate vanishes as Γ_{q}∼|q|^{3/5} in the low-|q| limit. We...
An on-chip electron spin resonance technique is applied to reveal the nature and origin of surface spins on Al_{2}O_{3}. We measure a spin density of 2.2×10^{17} spins/m^{2}, attributed to physisorbed atomic hydrogen and S=1/2 electron spin states on the surface. This is direct evidence for the nature of spins responsible for flux noise in quantum circuits, which has been an issue of interest ...
In a four terminal sample, microscopic time reversibility leads to symmetry relations between resistance measurements where the role of current and voltage leads are exchanged. These reciprocity relations are a manifestation of general Onsager-Casimir symmetries in equilibrium systems. We investigate experimentally the validity of time-reversal symmetry in a GaAs/Ga_{1-x}Al_{x}As Hall bar irrad...
