Dusky grouse seasonal resource selection in the Great Basin isolated mountain ranges of Nevada, USA

Wildlife Biology, EarlyView.
Dusky grouse Dendragapus obscurus are a montane forest grouse species with a paucity of information regarding their temporal and spatial resource use during critical times of high mortality and reproductive output. This lack of vital data may leave dusky grouse at risk of sub‐optimal management in many areas of their distribution, especially in the ...

Formation and control of electron molecules in artificial atoms: Impurity and magnetic-field effects

, 2000
Interelectron interactions and correlations in quantum dots can lead to spontaneous symmetry breaking of the self-consistent mean field resulting in formation of Wigner molecules.

Developing Implantable High‐Sensitivity Piezoelectric Thin‐Film Sensor to Monitor Partial Discharge of Generator Stator Windings

High Voltage, EarlyView.
ABSTRACT Insulation failures resulting from partial discharges (PD) in generator stator windings represent a leading cause of generator breakdowns. Conventional acoustic emission sensors for detecting PD ultrasonic signals are typically made from bulky piezoelectric materials and are restricted to external placement on the generator.

Restricted and unrestricted Hartree-Fock calculations of conductance for a quantum point contact

, 2002
Very short quantum wires (quantum contacts) exhibit a conductance structure at a value of conductance close to $0.7 \times 2e^2/h$. It is believed that the structure arises due to the electron-electron interaction, and it is also related to electron spin.

Triangular UHF algebras

Journal of Functional Analysis, 1990
AbstractIn this paper we classify triangular UHF algebras. The generic triangular UHF algebra is constructed as follows. Let (pn) be any sequence of positive integers such that pm|pn whenever m ⩽ n. For each n let Tpn be the algebra of all pn × pn upper triangular complex matrices, and for m ⩽ n, let σpn·pm: Tpm → Tpn be the mapping, x↦1d⊗x, where d ...

Analysing the Impact of Frequency Bands on Partial Discharge Measurement Outcomes in Generators Through Model‐Based Approach

High Voltage, EarlyView.
ABSTRACT The electromagnetic wave produced by a partial discharge (PD) covers a broad range of frequencies, from a few kHz to several 100 MHz. Because of the nonlinear response of the stator winding, each frequency component of the PD pulse experiences different levels of attenuation as it travels through the winding structure. Consequently, the choice

Research on Ultra‐Wideband Pulse Current Method for DC Partial Discharge Measurement

High Voltage, EarlyView.
ABSTRACT The conventional pulse current method is commonly used in AC or DC withstand voltage tests with partial discharge (PD) monitoring. Because of its relatively narrow measurement bandwidth, this method tends to ignore critical information in PD waveforms, making it difficult to eliminate pulse‐type interference under DC voltage conditions, where ...
