Multimodal Quad‐Finger Soft Robotic Hand With Dual‐Chamber Origami Actuator for Large‐Workspace Manipulation

open access: yesAdvanced Intelligent Systems, EarlyView.
A multimodal quad‐finger soft robotic hand (QDO hand) uses dual‐chamber straight–curved origami prismatic (SCOP) origami actuators. By coordinating positive and negative pressurization in the two chambers, each finger produces axial extension, contraction and bidirectional bending.

Beyond circular trigonometry: Parabolic functions from geometric identities

open access: yesAlifmatika
This paper presents an innovative extension of trigonometric functions to parabolic geometry, introducing the parabolic sine (sinp u) and parabolic cosine (cosp u) functions.

Which point sets admit a $k$-angulation?

open access: yesJournal of Computational Geometry, 2014
For \(k\ge 3\), a \(k\)-angulation is a 2-connected plane graph in which every internal face is a \(k\)-gon. We say that a point set \(P\) admits a plane graph \(G\) if there is a straight-line drawing of \(G\) that maps \(V(G)\) onto \(P\) and has the ...

Revisiting The Riemann Zeta Function at Positive Even Integers

open access: yes, 2017
Using Parseval's identity for the Fourier coefficients of $x^k$, we provide a new proof that $\zeta(2k)=\dfrac{(-1)^{k+1}B_{2k}(2\pi)^{2k}}{2(2k)!}$.Comment: 6 pages, no ...

Time‐Delayed Spiking Reservoir Computing Enables Efficient Time Series Prediction

open access: yesAdvanced Intelligent Systems, EarlyView.
This study proposes time‐delayed spiking reservoir computing (TDSRC) for efficient time series prediction. By concatenating time‐lagged states, TDSRC constructs an expanded readout feature vector without altering internal reservoir dynamics. This approach enables highly accurate forecasting with significantly fewer neurons, providing a resource ...

Composition of some positive linear integral operators

open access: yesDemonstratio Mathematica
This article is devoted to constructing sequences of integral operators with the same Voronovskaja formula as the generalized Baskakov operators, but having different behavior in other respects.

A spatial signature of sprawl: or the proportion and distribution of linear networkcircuits [PDF]

open access: yes, 2005
This paper sets out to investigate whether the frequency distribution ofthe linear network circuits within a graph-based representation of aroad transportation system can be helpful in identifying sprawl and, inparticular, whether a 'spatial signature of

Work Versus Force: Simultaneous Processes for Describing Interactions

open access: yesAdvanced Physics Research, EarlyView.
ABSTRACT Achieving a unified description of interactions remains an open challenge in theoretical physics, which currently describes four fundamental forces. This situation may be viewed differently when interactions are formulated in terms of processes (work as actio) rather than forces (force as actio), not only at the macroscopic level but also at ...

A note on some constants related to the zeta-function and their relationship with the Gregory coefficients

open access: yes, 2017
In this paper new series for the first and second Stieltjes constants (also known as generalized Euler's constant), as well as for some closely related constants are obtained.
