The $(\leq 6)$-half-reconstructibility of digraphs [PDF]
Let $G=(V,A)$ be a digraph. With every subset $X$ of $V$, we associate the subdigraph $G[X]=(X,A\cap (X\times X))$ of $G$ induced by $X$. Given a positive integer $k$, a digraph $G$ is $(\leq k)$-half-reconstructible if it is determined up to duality by ...

Universal properties of superconformal OPEs for 1/2 BPS operators in $3\leq D \leq 6$
, 2001 We give a general analysis of OPEs of 1/2 BPS superfield operators for the $D=3,4,5,6$ superconformal algebras OSp(8/4,R), PSU(2,2), F${}_4$ and OSp($8^*/4$) which underlie maximal AdS supergravity in $4\leq D+1\leq 7$.

Dynamic Obstacle Avoidance of Metamorphic Microrobots Using Concentric Sector Navigator
Advanced Intelligent Systems, EarlyView.Metamorphic magnetic microrobots are navigated using a concentric sector navigator for dynamic obstacle avoidance in both microroller and swarm states. After microroller transport, citrate‐triggered dissolution releases nanoparticles that reassemble into a controllable swarm.

Compactness of commutators of Toeplitz operators on q-pseudoconvex domains
Electronic Journal of Differential Equations, 2018 Let $\Omega$ be a bounded q-pseudoconvex domain in $\mathbb{C}^n$, $n \geq 2$ and let $1 \leq q \leq n-1$. If $\Omega$ is smooth, we find sufficient conditions for the $\overline\partial$-Neumann operator to be compact.

Advanced Intelligent Systems, EarlyView.A quadrupedal integrated leg‐arm robot with an underactuated reconfigurable body is developed. By using a Sarrus mechanism as the body, the robot enables reconfiguration through its supporting limbs, achieving mode switching without additional actuators.

An indirect measurement of gas evolution in galaxies at $0.5\leq z \leq 2.0$
, 2012 One key piece of information missing from high redshift galaxy surveys is the galaxies' cold gas contents. We present a new method to indirectly determine cold gas surface densities and integrated gas masses from galaxy star formation rates and to separate the atomic and molecular gas components.

Advanced Intelligent Systems, EarlyView.A hybrid mobile robot with a modular Variable‐Stiffness Bridge transitions between a rigid locomotion platform and a flexible, shape‐conforming body. By enclosing objects within its deformable structure rather than relying on dedicated end effectors, the robot achieves orientation‐regulated planar transport, with conformal contact quality shown to ...

Electronic Journal of Qualitative Theory of Differential Equations, 1998 We use a fixed point index theorem in cones to study the existence of positive solutions for boundary value problems of second-order functional differential equations of the form $$\left\{ \begin{array}{ll} y''(x)+r(x)f(y(w(x)))=0 ...

Sound Level Measurement, Monitoring and Management in Small Music Venues: Leq Averaging Time Interval [PDF]
This paper considers different Leq averaging time intervals and their effect on the dynamic range of live music as presented to an audience. Data was collected in four small and mid-sized music venues in Perth, Australia in 2019, and combined with an ...
