Slowly but steadily I clean up the mess I made in my notes when I moved to Obsidian from #orgmode and back again.
In addition I’m renaming the notes to #denote format and clean out some old stuff.
Today I looked through a file full of links and migrated them into Nextcloud Bookmarks…

A Smooshed BMOCZ Zero Constellation for CFO Estimation Without Channel Coding
In this study, we propose a new binary modulation on conjugate-reciprocal zeros (BMOCZ) zero constellation, which we call smooshed binary modulation on conjugate-reciprocal zeros (SBMOCZ), to address carrier frequency offset (CFO)-induced zero rotation without depending on channel coding. In our approach, we modify the phase mapping of Huffman BMOCZ by shrinking the angle between adjacent zeros, except for the first and last, to introduce a gap in the zero constellation. By discerning the gap l…

glass: ordered set data structure for client-side order books
The "ordered set" abstract data type with operations "insert", "erase", "find", "min", "max", "next" and "prev" is ubiquitous in computer science. It is usually implemented with red-black trees, $B$-trees, or $B^+$-trees. We present our implementation of ordered set based on a trie. It only supports integer keys (as opposed to keys of any strict weakly ordered type) and is optimized for market data, namely for what we call sequential locality. The following is the list of what we believe to be …

During the last week in May, the leading topic on the 5Calls app was opposition to a provision of the House budget bill restraining judges’ ability to enforce contempt sanctions (17,600 calls).
The rest of the Top 5 topics were slashing Medicare and Medicaid (13,658 calls);
cuttinggender-affirming care (7,697 calls);
attacks on so-called “woke” universities (7,319 calls);
and other “harmful provisions” in the megabill (7,142 calls).
The issues change slightly e…

Reporters Without Borders: there have been at least 31 attacks on journalists while covering the Los Angeles protests, including 27 attacks by law enforcement (David Bauder/Associated Press)

CNN correspondent and crew detained and escorted from Los Angeles protest zone
Police detained a CNN crew reporting on protests against immigration raids in Los Angeles. CNN correspondent Jason Carroll said an officer escorted them away from the protest late Monday and warned them to not return. On Sunday, an Australian journalist was hit in the leg by a rubber bullet and a British photographer was similarly injured on Saturday. National Press Club President Mike Balsamo urged officials to stop targeting, detaining, or obstructing journalists, and to guarantee journalists…

Vulnerability of electrical systems to total blackouts is not just a result of high penetration of renewables. The opposite applies in La Palma, Canarias, as in Cuba, when old thermal power plants fail. In La Palma, renewables have the lowest share (11%) of all Spain's islands.
Por qué los apagones se ceban con La Palma: un sistema aislado y una central térmica de hace medio siglo

Por qué los apagones se ceban con La Palma: un sistema aislado y una central térmica de hace medio siglo
La isla cuenta con una red eléctrica que depende en gran parte de una sola estación con varios grupos muy antiguos. Cuando esta sufre un problema, las posibilidades de un corte total del suministro se multiplican

Do solar panels lower the transformation of light into heat? If so now many km² would we need to offset the rising temperature?

On Apparent Absence of Green Gap in InGaN/GaN Quantum Disks and Wells Grown by Plasma-Assisted Molecular Beam Epitaxy

On Apparent Absence of Green Gap in InGaN/GaN Quantum Disks and Wells Grown by Plasma-Assisted Molecular Beam Epitaxy
III-nitride based full-color blue, green and red-light emitting diodes are critically important for a broad range of important applications. To date, however, green or red color III-nitride light emitters grown by conventional growth techniques are limited in efficiency compared to blue emitters. As opposed to metal-organic chemical vapor deposition (MOCVD), while grown by plasma-assisted molecular beam epitaxy (PAMBE), the most intense emission is generally observed in the green spectral regio…
