Adhesive hydrogel-enabled integrative fixation for cartilage and osteochondral repair

Secure attachment of repair constructs to native cartilage and underlying bone tissues remains a major unmet need in chondral and osteochondral surgery. Currently existing injectable or scaffold-based cell carriers, while biologically compatible, lack the mechanical integrity and interfacial adhesion. In most cases, a secondary fixation using suturing or fibrin glue remains necessary, which can be challenging in terms of achieving long-term integration and reproducible clinical outcomes. Here, we investigat

Vacuum-enhanced dielectric elastomer counterpulsation for in-vivo diastolic augmentation

Yves Perriard

Cardiac assist devices based on dielectric elastomer actuators (DEAs) offer a promising alternative to conventional mechanical circulatory support by providing soft and adaptive mechanical assistance. However, existing DEA-based systems face significant limitations in energy efficiency and effective hemodynamic modulation. This study presents a novel vacuum-enhanced DEA-based counterpulsation device and evaluates its performance in a porcine in-vivo model. We investigated two distinct implementation configu

A Social Justice Approach to Assistive Technology and Well-Being of People With Visual Disabilities in Low- and Middle-Income Countries: Qualitative Narrative Study

Background The United Nations’ third Sustainable Development Goal emphasizes ensuring healthy lives and promoting well-being (WB) for all, which requires effective assistive technology (AT) for persons with disabilities. In low- and middle-income countries (LMICs), however, AT remains largely inaccessible, and high abandonment rates indicate that many existing solutions fail to meet users’ needs. To improve AT design and effectiveness, a deeper understanding of users’ lived experiences and the ways AT influ

Effect of N-Terminal Myristoylation on the Active Conformation of Gα

G proteins are part of the G-protein-coupled receptor (GPCR) signal transduction cascade in which they transfer a signal from the membrane-embedded GPCR to other proteins in the cell. In the case of the inhibitory G-protein heterotrimer, permanent N-terminal myristoylation can transiently localize the G alpha(i) subunit at the membrane as well as crucially influence G alpha(i)'s function in the GTP-bound conformation. The attachment of lipids to proteins is known to be essential for membrane trafficking; ho

Urban Experience: Remix of Attachments

I propose an essay for understanding how we experiment the fluidity, the density and diversity of the urban space. I purpose to reveal what I call the remix experience, that is to say the habit to of newness and otherness. This habit shows us the importance of remixing in our urban life, and the various repeated attachments and detachments of our action courses. I will describe the repeated experiences of fluid attachments to beings and to objects, that is to say, to think singular orderings in fluid urban

Switchable fluorophores for protein labeling in living cells

Kai Johnsson

Numerous synthetic fluorophores have been developed that can switch their spectroscopic properties upon interaction with other molecules or by irradiation with light. In recent years, protein-labeling techniques have been introduced that permit the specific attachment of such molecules to proteins of interest in living cells. We review here how the attachment of switchable fluorophores to selected proteins of interest via self-labeling protein tags enables new applications in different areas of biology and

A G2-phase microtubule-damage response in fission yeast

Microtubules assume a variety of structures throughout the different stages of the cell cycle. Ensuring the correct assembly of such structures is essential to guarantee cell division. During mitosis, it is well established that the spindle assembly checkpoint monitors the correct attachment of sister chromatids to the mitotic spindle. However, the role that microtubule cytoskeleton integrity plays for cell-cycle progression during interphase is uncertain. Here we describe the existence of a mechanism, inde

Analysis of Stress Concentration at Longitudinal Attachment

Alain Nussbaumer

Following ICOM’s participation in the redaction of a new recommendation for the evaluation of existing railway-bridges, in collaboration with the SBB/CFF, new questions have been raised. Among those, the influence of a welded longitudinal attachment ends shape on its fatigue behaviour was of particular interest. Indeed, this detail has low fatigue strength (as low as detail category 56 according to SIA 263 [SIA 263]) and the possible shape improvements that are given in the code are costly to fabricate. The

Reaching Agreement with Unknown Participants in Mobile Self-Organized Networks in Spite of Process Crashes

André Schiper, David Cavin, Yoav Sasson

We consider the consensus problem in self-organized networks such as MANETs. Consensus oﬀers a means for reliably solving agreement related problems, which in a self-organized setting can help bring enhanced structure and reliability to the highly dynamic and disorganized environment of MANETs. We consider asynchronous networks with reliable communications channels. Neither the identity nor the number of nodes is initially known to the participants. This captures the self-organized nature of the network, wh

Attachment-induced ionization instability in electronegative capacitive RF discharges

Christoph Hollenstein, Laurent Fabien Hubert Sansonnens, Antoine Descoeudres

Attachment-induced ionization instability has been experimentally observed in O-2 and CF4 capacitive RF discharges using time-resolved voltage probe, Langmuir probe, optical emission and mass spectrometry measurements. This instability occurs under specific conditions of power and pressure, and produces synchronized oscillations in the kilohertz range on potentials, emission intensity and positive ion fluxes. In contrast, the SF6 plasma was observed to remain stable under all experimental conditions. This c

Protein chemistry in living cells

Kai Johnsson

Studying proteins in living cells generally requires the construction of a fusion protein between the protein of interest and an appropriate tag. Currently used fusion protein-based assays rely on the genetically encoded properties of the tag, which significantly limits their scope of applications. Here we present a general method for the in vivo labeling of fusion proteins with small mols. possessing functionalities that can not be genetically encoded. The specific attachment of the small mol. to the fusio

Capture numbers in the presence of repulsive adsorbate interactions

Harald Brune

Capture numbers are used in models of nucleation and growth on surfaces, and have been widely applied to predict nucleation densities and other quantities via rate equations. In conventional nucleation theory, much effort has historically been expended on obtaining good expressions for capture numbers in the diffusion-limited case. However, recent experiments and calculations have shown that weak repulsive interactions between adsorbate atoms on relatively smooth (e.g., close-packed metal) surfaces may shif

Time-resolved imaging of anodic arc root behavior during fluctuations of a dc plasma spraying torch

Christoph Hollenstein, Jean-Luc Dorier, Malko Gindrat

The fluctuating behavior of a Sulzer Metco F4 de plasma gun has been investigated by simultaneous measurement of the:time dependencies of the are voltage and of images from the nozzle interior. An end-on imaging arrangement using a mirror and a mask in the optical path from the are to the camera allows visualization of the anodic are attachment by strongly attenuating the bright emission from the are column, With the torch operating in the restrike mode, sequences of images have been acquired in synchroniza

On the practical use of weld improvement methods

Alain Nussbaumer

Many laboratory studies have shown the beneficial effects of weld improvement methods on the fatigue strength of welded details. However, no structural codes systematically include weld improvement methods in detail classification. The purpose of this paper is to discuss the possibilities of using these methods in practice on either new or existing structures. This paper provides the reader with practical rules for designing and computing the fatigue strength of improved welded joints. A computation method

An innovative flexible and accurate packaging technique suited to fabricate low cost micro optoelectronic modules

Several groups are presently investigating the opportunity to fabricate miniaturized optical devices characterized by high attachment precision. An automated surface mounted technique based on standardized supports of 10x10x4 mm(3) size and on active insitu alignment of the optical elements had been developed in our laboratories. This surface mounted device (SMD) technique is well suited for a flexible production of small optical devices and it allows a two dimensional layout. It is limited in precision to

A probabilistic model for ligand-cytoskeleton transmembrane adhesion: predicting the behavior of microspheres on the surface of migrating cells

Jean-Jacques Meister

A theoretical model describing the attachment and cytoskeletal coupling of microspheres to the dorsal surface of motile cells was developed. Integral membrane receptors beneath a ligand-coated microsphere are allowed to be either free, attached to the microsphere, bound to the rearward moving actin network, or linked to both the bead and the cytoskeleton, and to switch between these four states. The binding transitions being modeled as chemical reactions governed by rate constants taken from literature, the
