Tootfinder

Not upgrading all the SQS code using boto.sqs.Message to boto3 has finally bitten me on the ass as boto just doesn't work on Python 3.12 which is what I'm moving to.
And I'm moving it because 3.7 has become the 2.7 of Python 3. Whilst I originally targeted 3.9 that is slipping away too.
There is a lot of SQS going on, not just pipelining but logging. The logging is kind of Schroedinger logging as I don't bother with it unless I need to.

Quantum dynamics in confined pseudo-harmonic oscillator in a time-dependent moving
In this work, we present analytical solution of Schrödinger equation of confined pseudoharmonic potential in presence of a moving boundary condition, for an arbitrary angular momentum state. It turns out that an important quantity to probe the problem is internuclear distance ratio, which depends on the solution of Ermakov equation. The minimum value of time-dependent (TD) Heisenberg uncertainty product always remains greater than that of the minimum uncertainty product h/2. The TD average ene…

Single-File Diffusion of Active Brownian Particles
Single-file diffusion (SFD) is a key mechanism underlying transport phenomena in confined physical and biological systems. In a typical SFD process, microscopic particles are restricted to moving in a narrow channel where they cannot pass one another, resulting in constrained motion and anomalous long-time diffusion. In this study, we use Brownian dynamics simulations and analytical theory to investigate the SFD of athermal active Brownian particles (ABPs), a minimal model of active colloids. B…

The mantle-inner core gravitational mode of oscillation in a strong magnetic field regime
The mantle-inner core gravitational (MICG) mode is the free mode axial oscillation between the mantle and inner core sustained by the gravitational torque between their degree 2 order 2 density structures. Here, we investigate how the MICG mode is affected by oscillations of cylindrical surfaces in the fluid outer core in the form of Alfvén waves. The latter are triggered by oscillations of the tangent cylinder (TC) moving jointly with the inner core and propagate away from the rotation axis. …

Speaker Embeddings to Improve Tracking of Intermittent and Moving Speakers
Speaker tracking methods often rely on spatial observations to assign coherent track identities over time. This raises limits in scenarios with intermittent and moving speakers, i.e., speakers that may change position when they are inactive, thus leading to discontinuous spatial trajectories. This paper proposes to investigate the use of speaker embeddings, in a simple solution to this issue. We propose to perform identity reassignment post-tracking, using speaker embeddings. We leverage trajec…

On this single network each time interval is trained with the initial condition for (n+1)th as the solution obtained a…

We show that acceleration introduces rich effects that do not occur with uniform motion, including trans…

The main piping is black 2” flexible pipe plus some PVC Sched40.
Plumbing Question: Should I reduce diameter once (as pictured badly lol) when branching from the mainline and then have valves for each and long runs of smaller 3/4 or 1/2" line to each sprayer.
Or keep it to 2" throughout and reduce at the outlets?
I would rather have the valve controls centralized than have them spread about where the sprayers are (obv not an option for the bottom ones anyway)

Packed up my XBOX and large TV in the basement today :-(
I don't play video games every day, but 2 or 3 days a week, my daughter, who lives in Toronto, and I will play Halo online and defend the universe from Covenant forces. It's now 22 days until the moving trucks arrive, and planning for activities each day is underway. We have to allocate time for yard maintenance, packing, and cleaning. Accompanying music choices are important...

A meshless generalized finite difference method for solving the Stokes-Darcy coupled problem in static and moving systems
In this paper, a meshless Generalized Finite Difference Method (GFDM) is proposed to deal with the Stokes-Darcy coupled problem with the Beavers-Joseph-Saffman (BJS) interface conditions. Some high order GFDMs are proposed to show the advantage of the high order GFDM for the Stokes-Darcy coupled problem, which is that the high order method has high order accuracy and the convergence order. Some Stokes-Darcy coupled problems with closed interfaces, which has more complex geometric shape, are giv…

Lorentz invariant materials and metamaterials
We show that electromagnetic constitutive relations of materials, defined by a scalar permittivity, $\varepsilon$, and permeability, $μ$, are the same for all inertial observers provided that $\varepsilonμ= 1$ is satisfied. To highlight the practical power of our general result, we discuss schemes in which this property plays a significant role, such as Fresnel-Fizeau optical drag or modified Snell's law for moving dielectrics. We also proof that such a particular behavior can be extended to …

U.S. Begins Moving B-2 Bombers, as Trump Weighs Attack on Iran (Wall Street Journal)

Key to whether Trump can tilt America decisively into authoritarianism will be his efforts to assert control over the armed forces.
“Trump’s ramping up of the effort to politicize the military can still go in multiple directions,” Levitsky said.
“It could be really ugly and bad, because the only way that you can get from where we are to real authoritarianism like Nicaragua or Venezuela or Russia is if Trump has the military and security forces on his side,
and he’s taken s…

Classical Dirac particle I
In this work we produce a classical Lagrangian description of an elementary spinning particle which satisfies Dirac equation when quantized. We call this particle a classical Dirac particle. We analyze in detail the way we arrive to this model and how the different observables and constants of the motion can be expressed in terms of the degrees of freedom and their derivatives, by making use of Noether's theorem. The main feature is that the particle has a center of charge r, moving at the spee…

Omnidirectionally manipulated skyrmions in an orientationally chiral system
Skyrmions, originally from condensed matter physics, have been widely explored in various physical systems, including soft matter. A crucial challenge in manipulating topological solitary waves like skyrmions is controlling their flow on demand. Here, we control the arbitrary moving direction of skyrmions in a chiral liquid crystal system by adjusting the bias of the applied alternate current electric field. Specifically, the velocity, including both moving direction and speed can be continuous…

A space-time interface-fitted method for moving-subdomain distributed control problems with energy regularization
This paper investigates a space-time interface-fitted approximation of a moving-interface optimal control problem with energy regularization. We reformulate the optimality conditions into a variational problem involving both the state and adjoint. This problem is shown to be equivalent to our optimal control problem. Based on fully unstructured, space-time interface-fitted meshes, we propose and analyze a Petrov-Galerkin approximation of the problem. An optimal error estimate with respect to a …

Mirror Eyes: Explainable Human-Robot Interaction at a Glance
The gaze of a person tends to reflect their interest. This work explores what happens when this statement is taken literally and applied to robots. Here we present a robot system that employs a moving robot head with a screen-based eye model that can direct the robot's gaze to points in physical space and present a reflection-like mirror image of the attended region on top of each eye. We conducted a user study with 33 participants, who were asked to instruct the robot to perform pick-and-place…

It's only a week away until the moving truck arrives and puts an end to our 16 years in Caledon. Today, I'm taking some time to squeeze in 9 holes of golf with my brother, who has a cottage close to our new home. My car is packed with 11 different plants that we split from our current garden, over 70 individual plants for the new house. Two planters will have to wait for the next trip.

I think Harley is going to miss her large play area - which is a few acres, including our neighbour's yard where her buddy lives - and her front porch where she can keep watch while sunning herself. She is well trained to never approach the road out front, and we've never needed a fence. I think more walks are in our future, which is a good thing.
