Relative Factor Price Changes and Equity Prices [PDF]

open access: yes
This paper suggests that the decline in equity prices, and thus in Tobin's average q, during the 1970s may be attributable to changes in expected relative factor prices.

High-Q TM whispering-gallery modes in three-dimensional microcylinders [PDF]

open access: yes, 2007
We present a generation condition for realizing high-Q TM whispering-gallery modes (WGMs) in semiconductor microcylinders. For microcylinders with symmetry or weak asymmetry vertical waveguiding, we show that TM WGMs can have a high Q factor, with the ...

Spin Representations of the q-Poincare Algebra [PDF]

open access: yes, 2001
In der Quantenmechanik können freie Elementarteilchen durch irreduzible Darstellungen der Poincare-Algebra beschrieben werden. Im Rahmen der Darstellungtheorie der q-deformierten Poincaré-Algebra untersucht diese Arbeit den Spin von Teilchen auf einer ...

Primitive ideals and automorphism group of Uq+(B2) [PDF]

open access: yes, 2007
Let g be a complex simple Lie algebra of type B-2 and q be a nonzero complex number which is not a root of unity. In the classical case, a theorem of Dixmier asserts that the simple factor algebras of Gelfand-Kirillov dimension 2 of the positive part U ...

Multiport Antenna Q-factor

open access: yes
This article proposes an estimate of multiport antenna bandwidth based on a generalization of a single-port Q-factor. The explicit derivation is based on converting the stored energy matrix to its port equivalent and on the port parameters themselves. The work discusses the bandwidth dependencies on feeding and matching.

Self‐packaged MISL‐based miniaturized high Q factor bandpass filter

open access: yesElectronics Letters
This paper proposes a technique named self‐packaged metal integrated suspended line (MISL) to design a high Q factor bandpass filter (BPF). This unique construction simplifies the traditional suspended stripline and substrate integrated suspended line ...
