Advanced Intelligent Systems, EarlyView.This study presents a tensegrity joint with pneumatic artificial muscles integrated directly into its tensile network. Inspired by tensegrity spine structures, the joint's topology is developed and further optimized through an evolutionary algorithm, taking into account fabrication constraints and target applications.

Angewandte Chemie, EarlyView.This article describes a modular strategy to construct artificial cells able to regulate mammalian cell protein expression via vesicle‐based RNA communication. Considering the important role of extracellular vesicles in genetic information transfer, this artificial exosome design is a significant advance toward mimicking nucleic acid communication ...

Lessons from Toy-Models for the Dynamics of Loop Quantum Gravity
Symmetry, Integrability and Geometry: Methods and Applications, 2012 We review some approaches to the Hamiltonian dynamics of (loop) quantum gravity, the main issues being the regularization of the Hamiltonian and the continuum limit.

Quantum phenomenological gravitational dynamics: a general view from thermodynamics of spacetime
Journal of High Energy Physics, 2020 In this work we derive general quantum phenomenological equations of gravitational dynamics and analyse its features. The derivation uses the formalism developed in thermodynamics of spacetime and introduces low energy quantum gravity modifications to it.

DePerio: Deep Learning‐Based Oral Inflammatory Load Quantification for Periodontal Applications
Advanced Intelligent Systems, EarlyView.1) Inflammation and oral polymorphonuclear neutrophil (oPMN) Migration: Dental plaque accumulation leads to inflammation, prompting white blood cells (WBCs), particularly oPMNs, to migrate from blood vessels through the gingival epithelium into the oral cavity.

Dual Actuator Wave‐Like Navigator: An Untethered Soft Crawling Robot for Multisurface Locomotion
Advanced Intelligent Systems, EarlyView.Inspired by snails and earthworms, dual actuator wave‐like navigator (DAWN) is a soft, untethered robot that crawls using wave‐like motion generated by dual helical actuators wrapped in soft elastomer skins. Its modular design and cyclic pneumatic skin actuation improve performance across challenging terrains like sand, grass, and gravel.

Effects of underlying topology on quantum state discrimination
European Physical Journal C: Particles and FieldsIn this work, we show that quantum state discrimination can be modified due to a change in the underlying topology of a system. In particular, we explicitly demonstrate that the quantum state discrimination of systems with underlying discrete topology ...

Constraining the loop quantum gravity parameter space from phenomenology
Physics Letters B, 2018 Development of quantum gravity theories rarely takes inputs from experimental physics. In this letter, we take a small step towards correcting this by establishing a paradigm for incorporating putative quantum corrections, arising from canonical quantum ...
