A Sufficient Condition for k-Contraction of the Series Connection of Two Systems by Ofir, Ron, Margaliot, Michael, Levron, Yoash, Slotine, Jean-Jacques

“…The flow of contracting systems contracts 1-dimensional parallelotopes, i.e., line segments, at an exponential rate. One reason for the usefulness of contracting systems is that many interconnections of contracting sub-systems yield an overall contracting system. …”

Dual-frequency vortex-induced vibrations of long flexible stepped cylinders by Li, Ang, Mentzelopoulos, Andreas, Triantafyllou, Michael S., Fan, Dixia

“…The results show that the maximum in-line (IL) and cross-flow (CF) displacements and the frequency ratio of the stepped cylinder separated by individual frequency resemble those of a uniform cylinder vibrating in the uniform flow at a single frequency. …”

Microlensing Near Macro-Caustics by Weisenbach, Luke, Anguita, Timo, Miralda-Escudé, Jordi, Oguri, Masamune, Saha, Prasenjit, Schechter, Paul L.

“…Micro-caustics join into a connected network in a region around the macro-critical line of a width proportional to the surface density of microlenses; within this region, the increase of the mean magnification toward the macro-caustic is driven by the increase of the number of micro-images rather than individual magnifications of micro-images. …”

Chillbot: Content Moderation in the Backchannel by Seering, Joseph, Khadka, Manas, Haghighi, Nava, Yang, Tanya, Xi, Zachary, Bernstein, Michael

“…Moderating online spaces effectively is not a matter of simply taking down content: moderators also provide private feedback and defuse situations before they cross the line into harm. However, moderators have little tool support for these activities, which often occur in the backchannel rather than in front of the entire community. …”

Crack nucleation from a wedge disclination dipole with shift of rotation axes by Wu, Mao See

“…Biaxial dipoles are more stable when the rotation axis of each disclination approaches the defect line of the other disclination. If the negative disclinations of a uniaxial dipole and a biaxial dipole have the same axis shift, the critical nucleation stress of the biaxial dipole is larger if its positive disclination shift is more than that of the uniaxial dipole. …”

Phase-field modeling of interfacial debonding in multi-phase materials via an adaptive isogeometric-meshfree approach by Li, Weidong, Nguyen-Thanh, Nhon, Zhou, Kun

“…In this modeling, the crack and interface phase fields are introduced for the regularized representations of crack surfaces and interfaces, respectively, and a convenient approach is proposed for implementing the regularized energy related to both crack surfaces and interfaces without requiring the line integration along them. Numerical implementations of the present modeling are performed via the isogeometric-meshfree approach that constructs the equivalence between isogeometric and meshfree approximations. …”
