Numerical evidence for the Maldacena conjecture in two-dimensional N=(8,8) super Yang-Mills theory

open access: yes, 2005
The N=(8,8) super Yang-Mills theory in 1+1 dimensions is solved at strong coupling to directly confirm the predictions of supergravity at weak coupling.

Aggregate effect on the concrete cone capacity of an undercut anchor under quasi-static tensile load [PDF]

open access: yes, 2018
In the last decades, fastening systems have become an essential part of the construction industry. Post-installed mechanical anchors are frequently used in concrete members to connect them with other load bearing structural members, or to attach ...

Peptide Sequencing With Single Acid Resolution Using a Sub‐Nanometer Diameter Pore

open access: yesAdvanced Functional Materials, EarlyView.
To sequence a single molecule of Aβ1−42–sodium dodecyl sulfate (SDS), the aggregate is forced through a sub‐nanopore 0.4 nm in diameter spanning a 4.0 nm thick membrane. The figure is a visual molecular dynamics (VMD) snapshot depicting the translocation of Aβ1−42–SDS through the pore; only the peptide, the SDS, the Na+ (yellow/green) and Cl− (cyan ...

Topological surface states of strained Mercury-Telluride probed by ARPES [PDF]

open access: yes, 2013
The topological surface states of strained HgTe have been measured using high-resolution ARPES measurements. The dispersion of surface states form a Dirac cone, which origin is close to the top of the \ghh band: the top half of the Dirac cone is inside ...

Quantifying Spin Defect Density in hBN via Raman and Photoluminescence Analysis

open access: yesAdvanced Functional Materials, EarlyView.
An all‐optical method is presented for quantifying the density of boron vacancy spin defects in hexagonal boron nitride (hBN). By correlating Raman and photoluminescence signals with irradiation fluence, defect‐induced Raman modes are identified and established an relationship linking optical signatures to absolute defect densities. This enables direct

Experimental and Computational Crushing Behaviour of Laminated Composite Shells [PDF]

open access: yes, 2000
This thesis presents the effect of structural geometry, reinforcement type and hybridisation on the crushing behaviour, energy absorption, failure mechanism and failure mode of cylindrical, conical and compound composite shell.

Electroactive Liquid Crystal Elastomers as Soft Actuators

open access: yesAdvanced Functional Materials, EarlyView.
Electroactive liquid crystal elastomers (eLCEs) can be actuated via electromechanical, electrochemical, or electrothermal effects. a) Electromechanical effects include Maxwell stress, electrostriction, and the electroclinic effect. b) Electrochemical effects arise from electrode redox reactions.

Measurement of the first and second normal stress differences in a polystyrene melt with a cone and partitioned plate tool [PDF]

open access: yes, 2018
.: Step shear rate experiments in the range of $$0.1 10s^{ - 1} $$ the steady state value of -N2/N1 becomes larger if smaller cone angles are used. Data for α=0.148rad showed a better coincidence with the linear viscoelastic predictions of viscosity η ...

Comment on `Wedges, cones, cosmic strings and their vacuum energy'

open access: yes, 2013
A recent paper (2012 \emph{J. Phys.\ A} \textbf{45} 374018) is extended by investigating the behavior of the regularized quantum scalar stress tensor near the axes of cones and their covering manifold, the Dowker space.
