Stiffness‐Programmable Origami Robots With Tendon‐Driven Actuation via Multimaterial 3D Printing

Advanced Robotics Research, EarlyView.
Motion diversity is achieved in a tendon‐driven origami robot through programmable stiffness rather than modified actuation. Multimaterial 3D printing embeds soft creases, modular inserts redirect identical tendon inputs into distinct behaviors, and variable‐stiffness inserts enable real‐time switching.

Orbital diameters of primitive permutation groups [PDF]

, 2018
Let G be a transitive permutation group acting on a finite set X. Recall that G is primitive if there are no non-trivial equivalence relations on X which are preserved by G.

Nonreciprocal Swarmalators With Reconfigurable and Controllable Formations for Robot Collectives

Advanced Robotics Research, EarlyView.
Nonreciprocal swarmalator interactions are enabled through control barrier functions to transform self‐organizing robot collectives into reconfigurable, constraint‐aware systems. Complex two‐ and three‐dimensional shapes, continuous morphing, obstacle‐aware navigation, collective splitting, and object transport emerge from modulating agent‐level ...

The structure of transitive ordered permutation groups [PDF]

, 1999
summary:We give some necessary and sufficient conditions for transitive $l$-permutation groups to be $2$-transitive. We also discuss primitive components and give necessary and sufficient conditions for transitive $l$-permutation groups to be normal ...

MASH Background Confers Enhanced Disease Susceptibility and Acetaminophen Toxicity in iPSC‐Derived Liver Organoids

Advanced Science, EarlyView.
This work establishes a novel method for generating multicellular liver organoids from control and MASH donor iPSCs. The model recapitulates several disease‐specific characteristics, with MASH donor‐derived organoids showing higher susceptibility. Lipidomic profiling of MASH organoids closely resembles MASH liver biopsies.

Finite primitive permutation groups of rank 4 [PDF]

, 1993
In this thesis we classify finite primitive permutation groups of rank 4 . According to the 0'Nan-Scott theorem, a finite primitive permutation group is an affine group, an almost simple group, or has either simple diagonal action, product action or ...

Charting Endocrine Progenitors Across Species and Organs

Advanced Science, EarlyView.
Endocrine progenitors give rise to the hormone‐producing cells of the pancreas and intestine. Using single‐cell multiomics and proteomics, this study compares these progenitors across species, systems, and organs, mapping the conserved and species‐specific gene regulatory networks that guide their formation.

Primitive permutation groups and their section-regular partitions

Michigan Mathematical Journal, 2009
Let \(G\leqslant\text{Sym}(X)\) and \(\rho\) be a partition of \(X\). A `section' of \(\rho\) is a subset of \(X\) containing one representative for each class of the partition. The partition \(\rho\) is called `section-regular' if there exists a section \(S\) of \(\rho\) such that \(S^g\) is also a section of \(\rho\) for all \(g\in G\).

Finite permutation groups [PDF]

, 1979
Two problems in the theory of finite permutation groups are considered in this thesis: A. transitive groups of degree p, where p = 4q+1 and p,q are prime, B. automorphism groups of 2-graphs and some related algebras.

Neuromorphic Near‐Sensor and In‐Sensor Computing Enabled by Next‐Generation Material‐Based Sensors

Advanced Science, EarlyView.
This Review presents a structural framework that classifies neuromorphic sensing into near‐sensor and in‐sensor architectures, clarifying physical coupling between sensing and computation. The framework connects neural and synaptic device functions with recent advances in optical, mechanical, and chemical sensing, compares energy consumption and ...
