Advanced Biology, EarlyView.The unrolling of the peltate leaves in Syngonium podophyllum is analyzed and quantified (left‐hand side to center). These measurements serve to verify a mathematical model for leaf unrolling based on the model used in Schmidt (2007). An additional formula for obtaining a layer mismatch from a prescribed radius is derived.

IEEE Access, 2019 This paper addresses the asymptotic behavior of a particular type of information-plus-noise-type matrices, where the column and row numbers of the matrices are large and of the same order, while signals have diverged and the time delays of the channel ...

Topological asymptotic dimension
, 2022 We initiate a study of asymptotic dimension for locally compact groups. This notion extends the existing invariant for discrete groups and is shown to be finite for a large class of residually compact groups. Along the way, the notion of Hirsch length is extended to topological groups and classical results of Hirsch and Malcev are extended using a ...

Asymptotic dimension and uniform embeddings [PDF]
Groups, Geometry, and Dynamics, 2008 We study uniform embeddings of metric spaces, which satisfy some asymptotic tameness conditions such as finite asymptotic dimension, finite Assouad–Nagata dimension, polynomial dimension growth or polynomial growth, into function spaces. We show how the type function of a space with finite asymptotic dimension ...

Programmable Reconfiguration of Hybrid 4D Chiral Metamaterials via Mechanical and Thermal Stimuli
Advanced Engineering Materials, EarlyView.A class of hybrid chiral mechanical metamaterials is designed to achieve programmable reconfiguration through soft networks, hinges, and bilayer joints integrated with rigid units. Responsive to mechanical and thermal stimuli, these structures exhibit large volume changes, tunable deformation pathways, and both positive and negative thermal expansion ...

Performance analysis of zero-forcing coordinated MIMO transmission in interference channels
Tongxin xuebao, 2012 The performance of the zero-forcing (ZF) coordinated transmit strategy in multiple-input multiple-output (MIMO) interference channels was investigated.With the goal to derive analytical expression of its performance metric such as the sum rate and the ...

Asymptotic grand unification in SO(10) with one extra dimension
Journal of High Energy PhysicsAsymptotic grand unification provides an alternative approach to gradually unify gauge couplings in the UV limit, where they reach a non-trivial UV fixed point.

Ultrahigh Piezoelectricity in Truss‐Based Ferroelectric Ceramics Metamaterials
Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.By leveraging the unique combination of polarization direction and loading state, ultrahigh piezoelectricity is achieved through careful tuning of the relative density and scaling ratio in truss‐based ferroelectric metamaterials. This approach enables the simultaneous realization of extremely high piezoelectric constants and ultralow dielectric ...

On the Asymptotics of Quantizers in Two Dimensions
Journal of Multivariate Analysis, 1997 Optimal quantizers of the random vector \(X\) distributed over a region \(D \subset \mathbb{R}^d\) are a finite set of points in \(D\) such that the \(\gamma\)th mean distance of the random vector from this set is minimized. For \(\gamma =2\) and uniform bivariate random vectors, asymptotically optimal quantizers correspond to the centers of regular ...
