Integer division remains expensive on today's processors as the cost of integer multiplication declines. We present code sequences for division by arbitrary nonzero integer constants and runtime invariants using integer multiplication. The algorithms assume a two's complement
Simulating ratios of normalizing constants via a simple identity: A theoretical exploration
 Statistica Sinica
, 1996
"... Abstract: Let pi(w),i =1, 2, be two densities with common support where each density is known up to a normalizing constant: pi(w) =qi(w)/ci. We have draws from each density (e.g., via Markov chain Monte Carlo), and we want to use these draws to simulate the ratio of the normalizing constants, c1/c2. ..."

of the following simple identity: c1 c2 = E2[q1(w)α(w)] E1[q2(w)α(w)]. Here Ei denotes the expectation with respect to pi (i =1, 2), and α is an arbitrary function such that the denominator is nonzero. A main purpose of this paper is to provide a theoretical study of the usefulness of this identity, with focus
Massive Fields of Arbitrary HalfInteger Spin in Constant Electromagnetic Field
, 2008
"... We study the interaction of gauge fields of arbitrary halfinteger spins with the homogeneous electromagnetic field. We reduce the problem of obtaining the gaugeinvariant Lagrangian and transformations of the halfinteger spin fields in the external field to the purely algebraic problem of finding a ..."

Coil sensitivity encoding for fast MRI. In:
 Proceedings of the ISMRM 6th Annual Meeting,
, 1998
"... New theoretical and practical concepts are presented for considerably enhancing the performance of magnetic resonance imaging (MRI) by means of arrays of multiple receiver coils. Sensitivity encoding (SENSE) is based on the fact that receiver sensitivity generally has an encoding effect complementa ..."

complementary to Fourier preparation by linear field gradients. Thus, by using multiple receiver coils in parallel scan time in Fourier imaging can be considerably reduced. The problem of image reconstruction from sensitivity encoded data is formulated in a general fashion and solved for arbitrary coil
Chiral rings and anomalies in supersymmetric gauge theory
 JHEP
, 2002
"... Motivated by recent work of Dijkgraaf and Vafa, we study anomalies and the chiral ring structure in a supersymmetric U(N) gauge theory with an adjoint chiral superfield and an arbitrary superpotential. A certain generalization of the Konishi anomaly leads to an equation which is identical to the loo ..."

Integer and FloatingPoint Constant Multipliers for FPGAs
, 2008
"... Reconfigurable circuits now have a capacity that allows them to be used as floatingpoint accelerators. They offer massive parallelism, but also the opportunity to design optimised floatingpoint hardware operators not available in microprocessors. Multiplication by a constant is an important exampl ..."

Tensor network nonzero testing
, 2014
"... Tensor networks are a central tool in condensed matter physics. In this paper, we initiate the study of tensor network nonzero testing (TNZ): Given a tensor network T, does T represent a nonzero vector? We show that TNZ is not in the PolynomialTime Hierarchy unless the hierarchy collapses. We nex ..."

Nonexpanding Impulsive Gravitational Waves With an Arbitrary Cosmological Constant
