The total dry mass of human erythrocytes was determined by both interference microscopy and x-ray microradiography. The determination of mass per unit area, and calculation of total dry mass per cell were simplified by changing the shape of the cells to spheres which were then flattened to discs of constant thickness when smeared on glass slides for measurement of fixed cells by interferometry,...

Complex, non-Hermitian potentials V (x) 6= V (x) can often generate the standard, normalizable bound states ψ(x). Unfortunately, the idea [based on the use of a nonlocal ad hoc metric Θ(x, x) 6= δ(x − x) in Hilbert space] cannot directly be transferred to scattering [cf. H. F. Jones, Phys. Rev. D 78, 065032 (2008)]. We complement and modify this result by showing that a return to the causal and...

Smearing the gauge links of dynamical configurations removes small scale unphysical vacuum fluctuations und thus improves the chiral properties of lattice fermions. We present a new algorithm for the simulation of dynamical fermions coupled via smeared links based on the standard pure gauge overrelaxation and heatbath updatings. Smeared links play a fundamental role in making this algorithm eff...

We investigate the use of two kinds of staggered fermion operators, smeared and unsmeared. The smeared operators extend over a 44 hypercube, and tend to have smaller perturbative corrections than the corresponding unsmeared operators. We use these operators to calculate kaon weak matrix elements on quenched ensembles at β = 6.0, 6.2 and 6.4. Extrapolating to the continuum limit, we find BK(NDR,...

We investigate the effects of rare regions on the dynamics of Ising magnets with planar defects, i.e., disorder perfectly correlated in two dimensions. In these systems, the magnetic phase transition is smeared because static longrange order can develop on isolated rare regions. We first study an infinite-range model by numerically solving local dynamic mean-field equations. Then we use extrema...

We prove unboundedness and boundedness of the unsmeared and smeared chiral vertex operators, respectively. We use elementary methods in bosonic Fock space, only. Possible applications to conformal two dimensional quantum field theory, perturbation thereof, and to the perturbative construction of the sine-Gordon model by the Epstein-Glaser method are discussed. From another point of view the res...

One of the most serious problems of the staggered fermion lattice action is flavor symmetry violation. Smeared link staggered fermions can improve flavor symmetry by an order of magnitude relative to the standard thin link action. Over the last few years different smearing transformations have been proposed, both with perturbatively and non-perturbatively determined coefficients. What hindered ...
