Power of Supersymmetry in D-particle Dynamics [PDF]
, 2002 A new systematic method is developed to study to what extent the symmetry requirements alone, above all the invariance under 16 supersymmetries (SUSY), determine the completely off-shell effective action $\Gamma$ of a D-particle, i.e.

Einstein's fluctuation formula. A historical overview [PDF]
Fluctuation and Noise Letters, Vol. 6, No. 3 (2006) R11-R46, 2006 A historical overview is given on the basic results which appeared by the year 1926 concerning Einstein's fluctuation formula of black-body radiation, in the context of light-quanta and wave-particle duality. On the basis of the original publications (from Planck's derivation of the black-body spectrum and Einstein's introduction of the photons up to ...

Mirror Symmetry of Calabi-Yau Manifolds and Flat Coordinates [PDF]
, 1996 We study mirror symmetry of Calabi-Yau manifolds within the framework of the Gauss-Manin system. Applying the flat coordinates to the Gauss-Manin system for the periods, we derive differential equations for the mirror map in addition to the ordinary ...

Journal of Applied Polymer Science, EarlyView.ABSTRACT In recent years, natural‐fiber‐reinforced polymers have gained significant attention due to their sustainability and enhanced properties. This study used Canadian maple wood fiber as reinforcement in a polypropylene (PP). Fiber length and fiber content are known as key factors affecting the properties of the composites.

Biotechnology and Applied Biochemistry, EarlyView.ABSTRACT Actinobacillus succinogenes is a ruminal microorganism of biotechnological importance due to its capacity to produce succinic acid at high yields. Despite the scientific interest in this organism, molecular vehicles for the transfer and expression of genetic material are limited compared to the existing demand.

Dynamical density functional theory: phase separation in a cavity and the influence of symmetry [PDF]
, 2005 Consider a fluid composed of two species of particles, where the interparticle pair potentials $u_{11} = u_{22} \neq u_{12}$. On confining an equal number of particles from each species in a cavity, one finds that the average one body density profiles of

Nationwide resource utilization of dizziness/vertigo presentations to the ED
Eye &ENT Research, EarlyView.Abstract Objective This study aims to assess overall rates of neuroimaging (computed tomography [CT] or magnetic resonance imaging [MRI]) and cerebrovascular accidents (CVAs) in patients presenting to the emergency department (ED) with primary diagnoses of dizziness/vertigo to determine if neuroimaging is overused in this population.
