Changes in the volatile profile of Brassica oleracea due to feeding and oviposition by Murgantia histrionica (Heteroptera: Pentatomidae)

open access: yesEuropean Journal of Entomology, 2008
The mixture of volatile compounds emitted by Brassica oleracea var. sabauda changed significantly in response to feeding and/or oviposition by Murgantia histrionica (Heteroptera: Pentatomidae).

Discovery of Lasioglossum albescens (Smith, 1853) (Hymenoptera, Halictidae) from the Kinmen Islands, Taiwan [PDF]

open access: yesCheck List, 2020
Lasioglossum albescens (Smith, 1853) is recorded from Taiwan for the first time. The specimens were collected in the Kinmen Islands, several kilometers east of Xiamen, in Fujian, China. This species is distinguished from the other Taiwanese Lasioglossum (

Type IIB 7-branes in warped AdS 6: partition functions, brane webs and probe limit

open access: yesJournal of High Energy Physics, 2018
We study Type IIB supergravity solutions with spacetime of the form AdS 6×S 2 warped over a Riemann surface Σ, where Σ includes punctures around which the super-gravity fields have non-trivial SL(2, R) monodromy.

Eggs for breakfast? Analysis of a probable mosasaur biting trace on the Cretaceous echinoid Echinocorys ovata Leske, 1778 [PDF]

open access: yesFossil Record, 2018
Fossil biting traces (praedichnia) represent indirect evidence of predation and shed light on fossil predator–prey interactions and fossil food webs. Especially from echinoderm skeletons, biting traces are well known.

Oriented Open-Closed String Theory Revisited [PDF]

open access: yes, 1997
String theory on D-brane backgrounds is open-closed string theory. Given the relevance of this fact, we give details and elaborate upon our earlier construction of oriented open-closed string field theory.

Conformal blocks on a 2-sphere with indistinguishable punctures and implications on black hole entropy

open access: yesPhysics Letters B, 2016
The dimensionality of the Hilbert space of a Chern–Simons theory on a 3-fold, in the presence of Wilson lines carrying spin representations, had been counted by using its link with the Wess–Zumino theory, with level k, on the 2-sphere with points (to be ...

Intrathecal nusinersen administration in adult spinal muscular atrophy patients with complex spinal anatomy

open access: yesTherapeutic Advances in Neurological Disorders, 2020
Background: Intrathecal administration of nusinersen in adult spinal muscular atrophy (SMA) patients presents challenges owing to severe scoliosis and previous spinal surgery with metal implantation.

New Moduli Spaces from String Background Independence Consistency Conditions

open access: yes, 1996
In string field theory an infinitesimal background deformation is implemented as a canonical transformation whose hamiltonian function is defined by moduli spaces of punctured Riemann surfaces having one special puncture.

Entropy of Quantum Black Holes [PDF]

open access: yes, 2012
In the Loop Quantum Gravity, black holes (or even more general Isolated Horizons) are described by a SU(2) Chern-Simons theory. There is an equivalent formulation of the horizon degrees of freedom in terms of a U(1) gauge theory which is just a gauged ...
