Superluminal Signals: Causal Loop Paradoxes Revisited [PDF]
, 1998 Recent results demonstrating superluminal group velocities and tachyonic dispersion relations reopen the question of superluminal signals and causal loop paradoxes.

Choosing Your Ground on the Endangered Species Act: How Do the Ninth, Tenth, and District of Columbia Circuit Courts of Appeal Evaluate Water Management Decisions Made by Federal Water Agencies? [PDF]
, 2017 The purpose of this article is twofold. First, federal agencies are responsible for the development and implementation of ESA documents, and knowing what a court will look for and at when that document is challenged can help the agencies to develop a ...

Analytical Loss Model for Magnetic Cores Based on Vector Magnetic Circuit Theory
IEEE Open Journal of Power ElectronicsCurrently, some empirical formula methods, such as the Steinmetz equation, have been widely used in calculating high-frequency magnetic core loss. Although these methods may provide satisfactory accuracy under some certain conditions, they not only cannot present clear physical interpretation and fail to account for the origin and variation of losses ...

Theory of the circular closed loop antenna in the terahertz, infrared, and optical regions
, 2016 Modern antenna theory forms the bulwark of our knowledge of how radiation and metallic structures interact in the radio frequency (RF) and microwave (MW) regions.

Massive MIMO with Non-Ideal Arbitrary Arrays: Hardware Scaling Laws and Circuit-Aware Design [PDF]
, 2014 Massive multiple-input multiple-output (MIMO) systems are cellular networks where the base stations (BSs) are equipped with unconventionally many antennas, deployed on co-located or distributed arrays.

Impedance spectroscopy of ions at liquid-liquid interfaces
, 2013 The possibility to extract properties of an interface between two immiscible liquids, e.g., electrolyte solutions or polyelectrolyte multilayers, by means of impedance spectroscopy is investigated theoretically within a dynamic density functional theory ...

Analytic families of quantum hyperbolic invariants [PDF]
, 2015 We organize the quantum hyperbolic invariants (QHI) of $3$-manifolds into sequences of rational functions indexed by the odd integers $N\geq 3$ and defined on moduli spaces of geometric structures refining the character varieties.

, 1997 We study the asymptotic limiting function $W({G},q) = \lim_{n \to \infty}P(G,q)^{1/n}$, where $P(G,q)$ is the chromatic polynomial for a graph $G$ with $n$ vertices. We first discuss a subtlety in the definition of $W({G},q)$ resulting from the fact that

FEBS Letters, EarlyView.We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Non-adiabatic transitions in multi-level systems [PDF]
, 1999 In a quantum system with a smoothly and slowly varying Hamiltonian, which approaches a constant operator at times $t\to \pm \infty$, the transition probabilities between adiabatic states are exponentially small. They are characterized by an exponent that
