Construction of non-generalized Reed-Solomon MDS codes based on systematic generator matrix
Maximum distance separable (MDS) codes are considered optimal because the minimum distance cannot be improved for a given length and code size. The most prominent MDS codes are likely the generalized Reed-Solomon (GRS) codes. In 1989, Roth and Lempel constructed a type of MDS code that is not a GRS code (referred to as non-GRS). In 2017, Beelen et al. introduced twisted Reed-Solomon (TRS) codes and demonstrated that many MDS TRS codes are indeed non-GRS. Following this, the definition of TRS co…

Transient Stability Analysis of a Hybrid Grid-Forming and Grid-Following RES System Considering Multi-Mode Control Switching
The inherent control switching of renewable energy sources (RESs) during intricate transient processes introduces complexity to the dynamic behavior of modern power systems. This paper reveals the dynamic coupling between grid forming (GFM)/grid following (GFL)-based RES and dominant instability modes of the hybrid system. First, six control combinations are systematically investigated by pairing the two GFM-RES modes, normal control (NC) and current saturation (CS), with the three GFL-RES mode…

I was late to pick my daughter up from camp because #NYCParks closed a huge portion of Corona-Meadows Flushing Park. Apparently for some kind of music festival. There was, of course, no bike detour. The area has highways running through it, and the bridges over the highways are cordoned off. How do you get to

'One hour a day for better moods, less anxiety and feeling closer to their friends and family, all of it achieved by something as enjoyable as play.
Perhaps by fall, a zest for outdoor fun with phones left indoors will become a habit.
... encouraging children to go swimming or play street hockey is hardly a horrible way to give such a boost to their physical and mental health.
Open the door. Go outside and play. Put down your phones. Summer is calling."

The (not so) lazy days of summer
Canadian children aren’t getting enough exercise, and smartphones are partly to blame. The remedy? It’s right outside your door

I fucking hate the word "embrace," being autistic. It feels so fake, like a glitchy AI word that doesn’t match how my brain works.
It makes me want to scream inside because it’s too soft, too forced, and just wrong for me. I can’t use it without feeling like I’m lying to myself.

Falling stars: a fall-decorated rational shuffle theorem
In this paper, we formulate a rational analog of the fall Delta theorem and the Delta square conjecture. We find a new dinv statistic on fall-decorated paths on a $(m+k) \times (n+k)$ rectangle that simultaneously extends the previously known dinv statistics on decorated square objects and non-decorated rectangular objects. We prove a symmetric function formula for the $q,t$-generating function of fall-decorated rectangular Dyck paths as a skewing operator applied to $e_{m,n+km}$ and, condi…

Flowing Straighter with Conditional Flow Matching for Accurate Speech Enhancement
Current flow-based generative speech enhancement methods learn curved probability paths which model a mapping between clean and noisy speech. Despite impressive performance, the implications of curved probability paths are unknown. Methods such as Schrodinger bridges focus on curved paths, where time-dependent gradients and variance do not promote straight paths. Findings in machine learning research suggest that straight paths, such as conditional flow matching, are easier to train and offer b…

EL CMi: confirmation of triaxial pulsation theory
Triaxial pulsators are a recently discovered group of oscillating stars in close binary systems that show pulsations around three axes at the same time. It has recently been theoretically shown that new types of pulsation modes, the Tidally Tilted Standing (TTS) modes, can arise in such stars. Here, we report the first detection of a quadrupole TTS oscillation mode in the pulsating component of the binary system EL CMi following an analysis of TESS space photometry. Two dipole oscillations arou…

Generalized saturation game
We study the following game version of the generalized graph Turán problem. For two fixed graphs F and H, two players, Max and Mini, alternately claim unclaimed edges of the complete graph Kn such that the graph G of the claimed edges must remain F-free throughout the game. The game ends when no further edges can be claimed, i.e. when G becomes F-saturated. The H-score of the game is the number of copies of H in G. Max aims to maximize the H-score, while Mini wants to minimize it. The H-score …
