Published: January 2014

We construct model wave functions for a family of single-quasielectron states supported by the ν = 1/3 fractional quantum Hall fluid. The charge e* = e/3 quasielectron state is identified as a composite of a charge-2e* quasiparticle and a -e* quasihole, orbiting around their common center of charge with relative angular momentum nℏ > 0, and corresponds precisely to the "composite fermion" construction based on a filled n = 0 Landau level plus an extra particle in level n > 0. An effective three-body model (one 2e* quasiparticle and two -e* quasiholes) is introduced to capture the essential physics of the neutral bulk excitations.

In this work, we describe a computational tool designed to determine the local dielectric constants (ε) of charge-neutral heterogeneous systems by analyzing dipole moment fluctuations from molecular dynamics (MD) trajectories. Unlike conventional methods, our tool can calculate dielectric constants for dynamically evolving selections of molecules within a defined region of space, rather than for fixed sets of molecules. We validated our approach by computing the dielectric constants of TIP3P water nanospheres, achieving results consistent with literature values for bulk water.

Article Synopsis
  • The paper discusses the preparation of mesoscale polymer filaments to explore their properties, which exist between molecular and bulk scales.
  • It describes a method involving flow coating and evaporative deposition to create charged polymer filaments, specifically using thiol-ene reactions.
  • The research finds that these filaments change shape in different aqueous environments, revealing important information about the structure of soft materials at multiple length scales.

The objective of this study was to examine the impact of black soldier fly larval oil (BSFO) on feed consumption, nutritional digestibility, ruminal characteristics and methane (CH) estimation in Thai-indigenous steers. Four male Thai native steers (Bos indicus) weighing 383 ± 9.0 kg were used in this investigation.

The aim of our study was to assess the effects of low or high-starch diets with or without palmitic acid (C16:0) supplementation on the yield of milk, milk components, and energy partitioning of primiparous and multiparous dairy cows between mid and late-lactation. Thirty-two Holstein cows, 12 primiparous ([mean ± SD] 163 ± 33 d in milk) and 20 multiparous ([mean ± SD] 179 ± 37 d in milk), were used in a split-plot Latin square design. Parity was considered the main plot, and within each plot, treatments were then randomly assigned in a replicated 4 × 4 Latin square with 21 d periods and balanced for carryover effects.
