Joni Mitchell, Following Neil Young, Returns to Spotify After Protest
Her music has quietly reappeared on the streaming service, two years after a departure over what she called “lies” about Covid-19 vaccines in podcasts.

Over on the trading forums I ply daily, I get tweaked over smartasses who pooh-pooh Edwin Lefèvre's 101-year-old masterpiece, "Reminiscences of a Stock Operator" because the real protagonist, Jesse Livermore, ultimately failed. So, I wrote this to one such party pooper now:

Calculations of magnetic field produced by spin-vortex-induced loop currents in Bi$_2$Sr$_2$CaCu$_2$O$_{8+δ}$ thin films using the particle-number conserving Bogoliubov-de Gennes formalism
A theory for cuprate superconductivity predicts the existence of nano-sized loop currents called, `` spin-vortex-induced loop currents (SVILCs)''. We calculate magnetic fields produced by them for a model of Bi$_2$Sr$_2$CaCu$_2$O$_{8+δ}$ (Bi-2212) thin films composed of one surface and two bulk CuO$_2$ bilayers. In this model, bulk CuO$_2$ layers host stable spin-vortices around small polarons formed from doped holes; they give rise to a $U(1)$ gauge field described by the Berry connection fro…

A three-step approach to production frontier estimation and the Matsuoka's distribution
In this work, we introduce a three-step semiparametric methodology for the estimation of production frontiers. We consider a model inspired by the well-known Cobb-Douglas production function, wherein input factors operate multiplicatively within the model. Efficiency in the proposed model is assumed to follow a continuous univariate uniparametric distribution in $(0,1)$, referred to as Matsuoka's distribution, which is discussed in detail. Following model linearization, the first step is to sem…

On the Existence of Static Equilibria of a Cable-Suspended Load with Non-stopping Flying Carriers
This work answers positively the question whether non-stop flights are possible for maintaining constant the pose of cable-suspended objects. Such a counterintuitive answer paves the way for a paradigm shift where energetically efficient fixed-wing flying carriers can replace the inefficient multirotor carriers that have been used so far in precise cooperative cable-suspended aerial manipulation. First, we show that one or two flying carriers alone cannot perform non-stop flights while mainta…
