An analysis of ~65 NYT articles on US anti-trans legislation from the year to February 15, 2024: 66% did not quote a trans person, and 18% had misinformation (Media Matters for America)

Seen but not heard: The New York Times failed to quote trans people in over 60% of 2023 stories on anti-trans legislation
A new report from Media Matters and GLAAD finds that The New York Times excluded the perspectives of trans people from two-thirds of its stories about anti-trans legislation in the year following public criticism for its handling of the topic. Media Matters previously reported that the Times helped fuel a right-wing anti-trans panic in 2022 by platforming anti-trans extremists, painting rising transgender identification as a social contagion, and fearmongering about the costs of transgender acc…

The Fubini--Study metric on an `odd' Grassmannian is rigid
Following the ideas of Gasqui and Goldschmidt, we give an explicit description of the infinitesimal Einstein deformations admitted by the Fubini--Study metric on complex Grassmannians $G_{m}(\mathbb{C}^{n+m})$ with $m,n\geq 2$. The deformations were first shown to exist by Koiso in the 1980s but it has remained an open question as to whether they can be integrated to give genuine deformations of the Fubini--Study metric. We show that when $n+m$ is odd, the answer is no.

Exit Ripple Effects: Understanding the Disruption of Socialization Networks Following Employee Departures
Amidst growing uncertainty and frequent restructurings, the impacts of employee exits are becoming one of the central concerns for organizations. Using rich communication data from a large holding company, we examine the effects of employee departures on socialization networks among the remaining coworkers. Specifically, we investigate how network metrics change among people who historically interacted with departing employees. We find evidence of ``breakdown" in communication among the remaini…

Distributed Matrix Pencil Formulations for Prescribed-Time Leader-Following Consensus of MASs with Unknown Sensor Sensitivity
In this paper, we address the problem of prescribed-time leader-following consensus of heterogeneous multi-agent systems (MASs) in the presence of unknown sensor sensitivity. Under a connected undirected topology, we propose a time-varying dual observer/controller design framework that makes use of regular local and inaccurate feedback to achieve consensus tracking within a prescribed time. In particular, the developed analysis framework is applicable to MASs equipped with sensors of different …

Some results involving the $A_α$-eigenvalues for graphs and line graphs
Let $G$ be a simple graph with adjacency matrix $A(G)$, signless Laplacian matrix $Q(G)$, degree diagonal matrix $D(G)$ and let $l(G)$ be the line graph of $G$. In 2017, Nikiforov defined the $A_α$-matrix of $G$, $A_α(G)$, as a linear convex combination of $A(G)$ and $D(G)$, the following way, $A_α(G):=αA(G)+(1-α)D(G),$ where $α\in[0,1]$. In this paper, we present some bounds for the eigenvalues of $A_α(G)$ and for the largest and smallest eigenvalues of $A_α(l(G))$. Extremal graphs att…

Enhancing the Environmental Stability of Perovskite Thin Films via PMMA and AZ5214-Photoresist Coatings
We introduce a pioneering strategy to enhance the environmental stability of perovskite thin films, a critical step forward in advancing their application in optoelectronics. Through the innovative application of matrix encapsulation techniques, we focus on the stabilization of methylammonium lead iodide (MAPbI3) and methylammonium lead bromide (MAPbBr3) films. These films are meticulously prepared via a two-step solution deposition method under controlled ambient conditions. Our approach invol…

Filament drying is an interesting problem. As in this video, we typically see the before/after weight metric.
The question I always have: is there a way to quantify the actual effect on prints due to moisture?
In-line filament dryers seem like the right solution, but I don't know how to quantifiably test if they work. So, they end up falling into the snake oil category for me.

Long-Term Value of Exploration: Measurements, Findings and Algorithms
Effective exploration is believed to positively influence the long-term user experience on recommendation platforms. Determining its exact benefits, however, has been challenging. Regular A/B tests on exploration often measure neutral or even negative engagement metrics while failing to capture its long-term benefits. We here introduce new experiment designs to formally quantify the long-term value of exploration by examining its effects on content corpus, and connecting content corpus growth t…

$α_i$-Metric Graphs: Hyperbolicity
A graph is called $α_i$-metric ($i \in {\cal N}$) if it satisfies the following $α_i$-metric property for every vertices $u, w, v$ and $x$: if a shortest path between $u$ and $w$ and a shortest path between $x$ and $v$ share a terminal edge $vw$, then $d(u,x) \ge d(u,v) + d(v,x) - i$. The latter is a discrete relaxation of the property that in Euclidean spaces the union of two geodesics sharing a terminal segment must be also a geodesic. Recently in (Dragan & Ducoffe, WG'23) we initiated the …
