For vectors $X, Yin mathbb{R}^{n}$, we say $X$ is left matrix majorized by $Y$ and write $X prec_{ell} Y$ if for some row stochastic matrix $R, ~X=RY.$ Also, we write $Xsim_{ell}Y,$ when $Xprec_{ell}Yprec_{ell}X.$ A linear operator $Tcolon mathbb{R}^{p}to mathbb{R}^{n}$ is said to be a linear preserver of a given relation $prec$ if $Xprec Y$ on $mathbb{R}^{p}$ implies that $TXprec TY$ on $mathb...

The detection of Aspergillus galactomannan antigen (GM) with the Platelia Aspergillus (PA) enzyme-linked immunosorbent assay (Bio-Rad) is a method widely used for the diagnosis of invasive aspergillosis (IA), a life-threatening fungal infection (3, 7). In the last 2 years, several authors found GM in patients treated with piperacillin-tazobactam (TZP) and in TZP vials (1, 6, 8, 10, 11) while ot...

This study systematically investigated the electric direct current (DC) dependence of plastic flow behavior in a densified tetragonal ZrO2 polycrystal (TZP). Consequently, we observed an optimal density for tensile ductility. The maximum elongation 135% was achieved under 250 mA?mm?2 at furnace temperature 1000°C and initial strain rate 1 × 10?3 s?1. diffusional mass transport TZP accelerated b...

X-ray imaging in differential interference contrast (DIC) with submicrometer optical resolution was performed by using a twin zone plate (TZP) setup generating focal spots closely spaced within the TZP spatial resolution of 160 nm. Optical path differences introduced by the sample are recorded by a CCD camera in a standard full-field imaging and by an aperture photodiode in a standard scanning ...

The most widely used glass-ceramic is lithium disilicate (LD) because of its remarkable optical qualities, high strength, and simplicity manufacture. Greater marginal reduced porosity, net-shaped manufacturing by pressing are further benefits LD. development yttrium stabilized trigonal zirconia polycrystalline (Y-TZP) ceramics the result pursuit for a material with both mechanical capabilities,...

Different volume fractions (1.3, 2.6, and 7.6 Vol.%) of carbon nanotubes (CNTs) were dispersed within 8Y-TZP nanopowders. Mixed powder specimens were subsequently processed by spark plasma sintering (SPS) and effects of CNTs on the sintering process of 8Y-TZP/CNT composites was studied. Maintenance of CNTs through the SPS process was confirmed using TEM and Raman Spectroscopy. Studies on the si...
