Exact Solution of Semi-Flexible and Super-Flexible Interacting Partially Directed Walks [PDF]
, 2007 We provide the exact generating function for semi-flexible and super-flexible interacting partially directed walks and also analyse the solution in detail. We demonstrate that while fully flexible walks have a collapse transition that is second order and

A Soil-Dependent Approach for the Design of Novel Negative Stiffness Seismic Protection Devices
Applied Sciences, 2021 Conventional base isolation (BI) techniques require a great reduction in the fundamental frequency of the system in order to mitigate the structural dynamic responses due to earthquake excitations.

Extreme stiffness tunability through the excitation of nonlinear defect modes [PDF]
, 2016 The incremental stiffness characterizes the variation of a material's force response to a small deformation change. In lattices with noninteracting vibrational modes, the excitation of localized states does not have any effect on material properties ...

Design and Analysis of a Novel Compliant Tensile Testing Module Based on Buckled Fixed-Guided Beam
IEEE Access, 2021 The need to accurately measure the mechanical properties of freestanding thin films such as carbon nanotube reinforced nanocomposite thin films and various buckypaper is increasingly urgent. This paper presents the design and control of a novel compliant

MR Damper Controlled Vibration Absorber for Enhanced Mitigation of Harmonic Vibrations
Actuators, 2016 This paper describes a semi-active vibration absorber (SVA) concept based on a real-time controlled magnetorheological damper (MR-SVA) for the enhanced mitigation of structural vibrations due to harmonic disturbing forces.

Embedding negative structures to model holes and cut-outs [PDF]
, 2009 It has now been established that geometric boundary conditions and continuity conditions can be modelled by using either positive or negative stiffness or inertia type penalty term [1-5].

Hematopoietic (stem) cells—The elixir of life?
FEBS Letters, EarlyView.The aging of HSCs (hematopoietic stem cells) and the blood system leads to the decline of other organs. Rejuvenating aged HSCs improves the function of the blood system, slowing the aging of the heart, kidney, brain, and liver, and the occurrence of age‐related diseases.
