Non-Gaussian fluctuations of a probe coupled to a Gaussian field
The motion of a colloidal probe in a complex fluid, such as a micellar solution, is usually described by the generalized Langevin equation, which is linear. However, recent numerical simulations and experiments have shown that this linear model (...)

Cross-sections of doubly curved sheets as confined elastica
Although thin films are typically manufactured in planar sheets or rolls, they are often forced into three-dimensional (3D) shapes, producing a plethora of structures across multiple length scales. To understand this complex response, previous (...)

Damping-Driven Time Reversal for Waves
Damping is usually associated with irreversibility. Here, we present a counterintuitive concept to achieve time reversal of waves propagating in a lossless medium using a transitory dissipation pulse. Applying a sudden and strong damping in a (...)

Reconfiguration, Interrupted Aging and Enhanced Dynamics of a Colloidal Gel using Photo-Switchable Active Doping
We study light-activated quasi-2d gels made of a colloidal network doped with Janus particles. Following the gel formation, the internal dynamics of the gel are monitored before, during, and after the light activation. We monitor both the (...)

Accurate gene consensus at low nanopore coverage
Nanopore technologies allow high-throughput sequencing of long strands of DNA at the cost of a relatively large error rate. This limits its use in the reading of amplicon libraries in which there are only a few mutations per variant and (...)

Interactions between proteins and cellulose in a liquid crystalline media: Design of a droplet based experimental platform
Model systems are needed to provide controlled environment for the understanding of complex phenomena. Interaction between polysaccharides and proteins in dense medium are involved in numerous complex systems such as biomass conversion or plant (...)

Computational design of a minimal catalyst using colloidal particles with programmable interactionsâ€
Catalysis, the acceleration of chemical reactions by molecules that are not consumed in the process, is essential to living organisms but remains absent in physical systems that aspire to emulate biological functionalities with artificial (...)

Multilevel selection in the evolution of sexual dimorphism in phenotypic plasticity
Phenotypes are partly shaped by the environment, which can impact bothshort-term adaptation and long-term evolution. In dioecious species, thetwo sexes may exhibit different degrees of phenotypic plasticity and theor-etical models indicate that (...)

Silicon chambers for enhanced incubation and imaging of microfluidic dropletsâ€
Droplet microfluidics has become a powerful tool in life sciences, underlying digital assays, single-cell sequencing or directed evolution, and it is making foray in physical sciences as well. Imaging and incubation of droplets are crucial, yet (...)

Nanoparticle Taylor Dispersion Near Charged Surfaces with an Open Boundary
The dispersive spreading of microscopic particles in shear flows is influenced both by advection and thermal motion. At the nanoscale, interactions between such particles and their confining boundaries become unavoidable. We address the roles of (...)
