Advanced Healthcare Materials, EarlyView.NeuroVisio SyncPatch integrates skin‐conformal electromyography (EMG) electrodes with camera‐tracked markers to jointly assess muscle activity and three‐dimensional knee kinematics during rehabilitation. Parallel feedback pathways provide real‐time kinematic guidance during movement and post‐trial neuromuscular feedback.

Twistor actions for non-self-dual fields; a new foundation for twistor-string theory
, 2005 Twistor space constructions and actions are given for full Yang-Mills and conformal gravity using almost complex structures that are not, in general, integrable. These are used as the basis of a derivation of the twistor-string generating functionals for

Universal Conductance Fluctuations in Quantum Anomalous Hall Insulators
Advanced Materials, EarlyView.Universal conductance fluctuations are observed in mesoscopic quantum anomalous Hall insulators. Two distinct fluctuation patterns are identified, arising from different interference processes of bulk and chiral edge states, respectively. These findings unveil rich quantum interference phenomena in quantum anomalous Hall insulators and provide insights

3D conformal field theory in twistor space
Journal of High Energy PhysicsThe aim of this paper is to study three dimensional Lorentzian conformal field theories in twistor space. We formulate the conformal Ward identities and solve for two and three point Lorentzian Wightman functions.

Twistor spaces for HKT manifolds [PDF]
, 1996 We construct the twistor space associated with an HKT manifold, that is, a hyper-K\"ahler manifold with torsion, a type of geometry that arises as the target space geometry in two-dimensional sigma models with (4,0) supersymmetry.

String theory in twistor space and minimal tension holography
Journal of High Energy PhysicsExplicit examples of the AdS/CFT correspondence where both bulk and boundary theories are tractable are hard to come by, but the minimal tension string on AdS 3 × S 3 × T 4 is one notable example.

Conformal higher spin scattering amplitudes from twistor space
Journal of High Energy Physics, 2017 We use the formulation of conformal higher spin (CHS) theories in twistor space to study their tree-level scattering amplitudes, finding expressions for all three-point M H V ¯ $$ \overline{\mathrm{MHV}} $$ amplitudes and all MHV amplitudes involving ...

Integrable Complex Structures on Twistor Spaces [PDF]
The Quarterly Journal of Mathematics, 2019 Abstract We introduce integrable complex structures on twistor spaces fibered over complex manifolds. We then show, in particular, that the twistor spaces associated with generalized Kahler, SKT and strong HKT manifolds all naturally admit complex structures.

The Abstract Twistor Space of the Schwarzschild Space-Time
, 1998 Solutions are obtained to the abstract twistor structure equations of the Schwarzschild space-time. An abstract twistor ideal is built and its equations solved for a three-parameter set of abstract twistor surfaces.
