Influence of in-Plane Deformation in Higher Order Beam Theories

open access: yesJournal of Mechanical Engineering, 2018
Comparing Euler-Bernoulli or Tismoshenko beam theory to higher order beam theories, an essential difference can be depicted: the additional degrees of freedom accounting for out-of plane (warping) and in-plane (distortional) phenomena leading to the ...

Construction of warped time-frequency representations on nonuniform frequency scales, Part II: Integral transforms, function spaces, atomic decompositions and Banach frames

open access: yes, 2016
We present a novel family of continuous linear time-frequency transforms adapted to a multitude of (nonlinear) frequency scales. Similar to classical time-frequency or time-scale representations, the representation coefficients are obtained as inner ...

Poka: A Necro‐Robot Beetle with a Measured Payload Ratio of 6847%

open access: yesAdvanced Robotics Research, EarlyView.
Here, Poka, a necro‐robot beetle with the ability to carry more than 68 times its own weight, is introduced, making it also a walking robot with the highest payload ratio measured to date. This paper is concerned with the design, manufacture and validation of ‘Poka', a novel millimetre‐scale necro‐robot aimed at bridging the performance gap between ...

A Force Myography (FMG) Armband Based on Micro‐Structured Textile‐Pressure Sensors for Human‐Machine Interface (HMI)

open access: yesAdvanced Sensor Research, EarlyView.
This study introduces a textile‐based capacitive pressure sensor featuring a triangular prism microstructure, which significantly enhances sensitivity to 5.52% kPa−¹ and supports a wide sensing range up to 330 kPa. The sensor's performance is validated in a 4‐channel capacitive pressure‐based force myography (cFMG) armband for gesture recognition ...

Warping Functional Data in R and C via a Bayesian Multiresolution Approach

open access: yesJournal of Statistical Software, 2013
Phase variation in functional data obscures the true amplitude variation when a typical cross-sectional analysis of these responses would be performed.

Enhanced Activities of OCT4 and SOX2 Promote Epigenetic Reprogramming by Shortening G1 Phase

open access: yesAdvanced Science, EarlyView.
Fusing the VP16 domain to OCT4 and SOX2 (OvSvK) enhances iPSC generation by activating downstream targets, including those regulating the cell cycle. This accelerates reprogramming by shortening the G1 phase and reducing H3K27me3 levels. Modulating Ccnd1, Cdkn2a, and Ccne1 improves efficiency, linking cell cycle to epigenetic remodeling.

Non-Uniform Torsion Behavior of Thin-Walled Beams According to the Finite Element Method

open access: yesSlovak Journal of Civil Engineering
This study is based on a theory for analyzing non-uniform torsion in thin-walled beams made of homogeneous elastic material with arbitrary cross-sections by incorporating the effect of the shear deformation of a cross-section.

Asymmetrically warped spacetimes [PDF]

open access: yesProceedings of International Europhysics Conference on High Energy Physics — PoS(hep2001), 2001
We investigate spacetimes in which the speed of light along flat 4D sections varies over the extra dimensions due to different warp factors for the space and the time coordinates (``asymmetrically warped'' spacetimes). The main property of such spaces is that while the induced metric is flat, implying Lorentz invariant particle physics on a brane, bulk
