Fears that falling birth rates in the US could lead to population collapse are based on faulty assumptions
Pronatalism—the belief that low birth rates are a problem that must be reversed—is having a moment in the U.S.

Trajectory control of a suspended load with non-stopping flying carriers
This paper presents the first closed-loop control framework for cooperative payload transportation with non-stopping flying carriers. Building upon grasp-matrix formulations and internal force redundancy, we propose a feedback wrench controller that actively regulates the payload's pose while an optimization layer dynamically shapes internal-force oscillations to guarantee persistent carrier motion. Preliminary experimental results on multirotor UAVs validate the model assumptions, and numerica…

Fear of flying therapy is about reframing the flight experience;
if my mind’s eye squints,
I can almost interpret my sweating palms and pounding heartbeat as a kind of buzz.
But this requires repeated, strenuous effort,
and the result is a mental exhaustion that makes the worst-case scenario appealing:
succumbing to my fears and never flying again.
I imagine this as analogous to what many Americans, aerophobic or not, are feeling.
It’s simply easier…

For those trying to overcome their fears of flying, it’s been . . . a challenging time to say the least.

Generalized ODE reduction algorithm with bounded degree transformation
As a generalization of our previous result\cite{huang2025algorithm}, this paper aims to answer the following question: Given a 2-dimensional polynomial vector field $y^{\prime}=\frac{M(x,y)}{N(x,y)}$, how to find a rational transformation $y \to \frac{A(x,y)}{B(x,y)}$ with bounded degree numerator, the inverse of which transforms this vector field into a simpler form $y^{\prime}=\sum_{i=0}^nf_i(x)y^i$. Such a structure, often known as the generalized Abel equation and has been studied in variou…

Finite element analysis of a nonlinear heat Equation with damping and pumping effects
We study the following nonlinear heat equation with damping and pumping effects (a reaction-diffusion equation) posed on a bounded simply connected convex domain $Ω\subset \mathbb{R}^d$, $d \geq 1$ with Lipschitz boundary $\partialΩ$: $$ \frac{\partial u(t)}{\partial t} - νΔu(t) + α|u(t)|^{p-2}u(t) - \sum_{\ell=1}^M β_{\ell} |u(t)|^{q_{\ell}-2}u(t) = f(t), \quad t>0, $$ subject to homogeneous Dirichlet boundary conditions and the initial condition $u(0)=u_0$, where $2 …

Local uniqueness and non-degeneracy of blowup solutions for regular Liouville systems
We study the following Liouville system defined on a compact Riemann surface $M$, \begin{equation} -Δu_i=\sum_{j=1}^n a_{ij}ρ_j\Big(\frac{h_j e^{u_j}}{\int_Ωh_j e^{u_j}}-1\Big)\mbox{ in }M\mbox{ for }i=1,\cdots,n,\nonumber \end{equation} where the coefficient matrix $A=(a_{ij})_{n\times n}$ is nonnegative, $h_1, \ldots, h_n$ are positive smooth functions, and $ρ_1, \ldots, ρ_n$ are positive constants. For the blowup solutions, we establish their uniqueness and non-degeneracy based on nat…
