A Proof‐of‐Concept Assessment of a Novel Wearable Eyelid Muscle Device: A Pre‐Clinical Animal Cadaver Study for Eyelid Closure Restoration

open access: yesAdvanced Robotics Research, EarlyView.
This article introduces a soft wearable eyelid sling device incorporating a hydraulic soft artificial muscle (SAM) for achieving complete closure of an eyelid. The SAM is driven by a cam mechanism that provides a displacement profile closely matched with those of a healthy eyelid.

Holographic corrections to the Veneziano amplitude

open access: yesPhysics Letters B, 2017
We propose a holographic computation of the 2→2 meson scattering in a curved string background, dual to a QCD-like theory. We recover the Veneziano amplitude and compute a perturbative correction due to the background curvature.

Non-Critical Strings, Del Pezzo Singularities And Seiberg-Witten Curves [PDF]

open access: yes, 1996
We study limits of four-dimensional type II Calabi-Yau compactifications with vanishing four-cycle singularities, which are dual to $\IT^2$ compactifications of the six-dimensional non-critical string with $E_8$ symmetry.

Higher derivative corrections to string inflation

open access: yesJournal of High Energy Physics
Abstract We quantitatively estimate the leading higher derivative corrections to $$ \mathcal{N} $$ N = 1 supergravity derived from IIB string compactifications and study how they may affect moduli stabilisation and LVS ...

Multi‐Material Additive Manufacturing of Soft Robotic Systems: A Comprehensive Review

open access: yesAdvanced Robotics Research, EarlyView.
This review explores the transformative role of multi‐material additive manufacturing (MMAM) in the development of soft robotic systems. It presents current techniques, materials, and design strategies that enable functionally graded and adaptive structures.

N-flation

open access: yes, 2005
The presence of many axion fields in four-dimensional string vacua can lead to a simple, radiatively stable realization of chaotic inflation.Comment: 16 pages, 0 figures, latex; v2: added refs; v3: more refs, correction to \S2.

Enabling Real‐Time Shape‐Sensing in Soft Robots via a Miniaturized, Single‐Signal, Color‐Tuned Soft Optical Sensor

open access: yesAdvanced Robotics Research, EarlyView.
A miniaturized soft optical sensor that uses thin film color tuning enables real‐time 3D shape‐sensing from a single red–green–blue (RGB) signal. When integrated into a soft robot, it enables closed‐loop control and autonomous navigation in a phantom lung environment without the need for onboard electronics, achieving sub‐millimeter accuracy through ...

Noncommutative geometry inspired rotating black string

open access: yes, 2017
Noncommutativity is an idea dating back to the early times of Quantum Mechanics and that string theory induced noncommutative (NC) geometry which provides an effective framework to study short distance spacetime dynamics. Also, string theory, a candidate

Strings and the Holographic Description of Asymptotically de Sitter Spaces [PDF]

open access: yes, 2002
Asymptotically de Sitter spaces can be described by Euclidean boundary theories with entropies given by the modified Cardy--Verlinde formula. We show that the Cardy--Verlinde formula describes a string with a rescaled tension which in fact is a string at

Higher-Genus Corrections to Black-String Solution [PDF]

open access: yesModern Physics Letters A, 1997
One-string-loop (torus topology) corrections to black-string backgrounds corresponding to gauged SL (2,R)× R/R WZW model are calculated using β-function equations derived from string-loop-corrected effective action. Loop-corrected backgrounds are used to calculate ADM mass of the black string.
