Activism thrives on connection, yet our passion can create barriers; nonviolent communication, focusing on understanding and compassion rather than blame or argument, bridges these divides. full article @ https://www.brichapman.com/p/nonviolent-communication-for-activism

Julia GraphBLAS with Nonblocking Execution
From the beginning, the GraphBLAS were designed for ``nonblocking execution''; i.e., calls to GraphBLAS methods return as soon as the arguments to the methods are validated and define a directed acyclic graph (DAG) of GraphBLAS operations. This lets GraphBLAS implementations fuse functions, elide unneeded objects, exploit parallelism, plus any additional DAG-preserving transformations. GraphBLAS implementations exist that utilize nonblocking execution but with limited scope. In this paper, we d…

Study reveals the extent to which nanoplastic pollutes the North Atlantic
Plastic waste pollutes oceans across all regions of the world. Marine animals may become entangled in larger plastic debris such as nets and bags or mistake smaller pieces for food. Ingested plastic can block or injure the gastrointestinal tract. The smallest plastic particles in the micro and nano range are mostly excreted, but a small proportion can pass through the intestinal wall and enter the bloodstream.

Failure of Lichnerowicz-type result in parabolic geometries of real rank at least $3$
Given a Yamaguchi nonrigid parabolic model geometry $(G,P)$ with $G$ simple of real rank at least $3$, we use techniques developed by Erickson to establish the existence of closed, nonflat, essential, regular, normal Cartan geometries modeled on $(G,P)$. Yamaguchi nonrigidity is a necessary condition for admitting nonflat, regular, normal examples. This rules out Lichnerowicz-type conjectures for these model geometries.

GOOD TROUBLE LIVES ON: · John Lewis Actions
Good Trouble Lives On is a national day of nonviolent action to respond to the attacks posed on our civil and human rights by the Trump administration and to remind them that in America, the power lies with the people. On July 17, the anniversary of Congressman John Lewis’s passing, we’re taking action across the country to defend our democracy and carry forward his legacy of Good Trouble. From voter suppression bills like the SAVE Act to the criminalization of protest, the Trump adminis…

Integral Cayley graphs over a nonabelian group of order $8n$
A graph is called an integral graph when all eigenvalues of its adjacency matrix are integers. We study which Cayley graphs over a nonabelian group $$ T_{8n}=\left\langle a,b\mid a^{2n}=b^8=e,a^n=b^4,b^{-1}ab=a^{-1} \right \rangle $$ are integral graphs. Based on the group representation theory, we first give the irreducible matrix representations and characters of $T_{8n}$. Then we give necessary and sufficient conditions for which Cayley graphs over $T_{8n}$ are integral graphs. As applicatio…

Toward Needs-Conscious Design: Co-Designing a Human-Centered Framework for AI-Mediated Communication
We introduce Needs-Conscious Design, a human-centered framework for AI-mediated communication that builds on the principles of Nonviolent Communication (NVC). We conducted an interview study with N=14 certified NVC trainers and a diary study and co-design with N=13 lay users of online communication technologies to understand how NVC might inform design that centers human relationships. We define three pillars of Needs-Conscious Design: Intentionality, Presence, and Receptiveness to Needs. Drawi…

Adiabatic nonabelian braiding of imperfect Majoranas
Demonstration of a nontrivial result of quasiparticle exchange (or braiding) is usually considered the definitive proof of a topological phase with nonabelian excitations, such as Majorana bound states (MBSs). However, in finite systems with disorder and smooth potential variations, the MBSs are imperfect in the sense that they are not fully isolated in space and can, to a varying degree, resemble conventional fermions. Here, we study the braiding properties of isolated MBSs, regular fermions, …

New research calls for global action on micro and nanoplastics in the atmosphere
Scientists at the University of Manchester are calling for the creation of a global network of air monitoring stations to track the movement of airborne plastic pollution, which may be traveling further and faster around the planet than previously thought.
