New synonym of Tipula (Vestiplex) wahlgrenana Alexander, 1968 (Diptera: Tipulidae)

open access: yesBiodiversity Data Journal, 2014
Based on examination of type specimens a crane fly species Tipula (Vestiplex) hugueniniana Alexander, 1971 is proposed as junior synonym of Tipula (V.) wahlgrenana Alexander, 1968. The new synonymy is based on similarity of male genitalia.

Effects of aging and thermal cycling on the microstructure and damping behaviors of a porous CuAlMn shape memory alloy

open access: yesJournal of Materials Research and Technology, 2020
Effects of aging and thermal cycling on the microstructure and damping behaviors of a porous CuAlMn shape memory alloy (SMA) were studied. It was found that with increasing aging temperature the intensity of the internal friction peak initially increased,

SN2013fs and SN2013fr: Exploring the circumstellar-material diversity in Type II supernovae

open access: yes, 2018
We present photometry and spectroscopy of SN2013fs and SN2013fr in the first 100 days post-explosion. Both objects showed transient, relatively narrow H$\alpha$ emission lines characteristic of SNeIIn, but later resembled normal SNeII-P or SNeII-L ...

Vortex Washboard Voltage Noise in Type-II Superconductors [PDF]

open access: yes, 2008
In order to characterize flux flow through disordered type-II superconductors, we investigate the effects of columnar and point defects on the vortex velocity / voltage power spectrum in the driven non-equilibrium steady state.

Carcinomas and Carcinoid Tumors of the Lungs and Bronchi in Children and Adolescents: The EXPeRT Recommendations

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Primary lung carcinomas and bronchial carcinoid tumors (BC) are very rare malignancies in childhood. While typical BC and mucoepidermoid carcinomas are mostly low‐grade, localized tumors with a more favorable prognosis than in adults, necessitating avoidance of overtreatment, adenocarcinomas of the lung are often diagnosed at advanced disease ...

On Madagascan Dichaetomyia species (Diptera: Muscidae): redescriptions of six species

open access: yesHistoria Naturalis Bulgarica, 2022
Several original descriptions of the Madagascan Dichaetomyia species originating from earlier years do not correspond to today’s requirements since taxonomic characters which are used today successfully for differentiating species have received little or

Type I superconductivity in Dirac materials [PDF]

open access: yesJournal of Physics: Condensed Matter, 2018
Superconductivity of the second kind was observed in many 3D Weyl and Dirac semi-metals. However in PdT e2, superconductivity is clearly of the first kind. This is very rare in Dirac semi - metals, but is expected in clean conventional metallic superconductors with 3D parabolic dispersion relation.
