A Concise Review of Recently Synthesized 2D Carbon Allotropes: Amorphous Carbon, Graphynes, Biphenylene and Fullerene Networks
Two-dimensional (2D) carbon allotropes have received considerable attention due to their unique properties and potential applications in several fields, including electronics, catalysis, energy storage, and sensing. Following the experimental realization of graphene, numerous other 2D carbon structures have been proposed and, in some cases, successfully synthesized. This work presents a concise review of the recently experimentally realized 2D carbon allotropes, including graphynes, biphenylene…

From my LinkedIn post: “Telling your dev team to use AI coding tools is like telling your 2010 ops team to use AWS. They didn’t know how to code, they were ticket and click-it VMware people… developers who don’t have product management mindset or have never managed a dev team will fail by trying to micromanage the output of the tool rather than specifying the outcome of the product and managing the agent team to deliver that outcome.”

Back in 2010 when we first started using AWS to run Netflix, the AWS services were very incomplete, somewhat unreliable, had scaling issues, but were super fast to provision compared to filing tickets and waiting for data center ops teams to do what we need. We worked around the issues, built a new cloud native developer driven architecture and scaled Netflix at speed. At the time many people said we were crazy to run a large enterprise on cloud and would be back in datacenters when it failed. …

A Path towards Thresholdless Colloidal Quantum Dot Lasers by Solving Decades of Mythology on Optical Gain
The semiconductor quantum dot (CQD) was first conceived in the 1980s as offering potential for future lasers. Following high quality solution phase synthesis of colloidal CQD (CCQD) in 1993, optical gain was first demonstrated in 2000 via stimulated emission (SE) measurements. Decades of phenomenology have given rise to a Standard Model of optical gain in CCQD based upon two assumptions: a biexciton is required to achieve optical gain, and short biexciton lifetimes limit the efficient developme…

Effect of Deposition Pressure on the Superconductivity of Ti40V60 Alloy Thin Films
The growth and characterization of high quality superconducting thin films is essential for fundamental understanding and also for the use of these films in technological applications. In the present study, Ti40V60 alloy thin films have been deposited using DC magnetron co sputtering of Ti and V at ambient temperatures. The effect of deposition pressure on the film morphology, superconducting and normal state properties has been studied. Measurement of electrical resistance as a function of tem…

When Instructions Multiply: Measuring and Estimating LLM Capabilities of Multiple Instructions Following
As large language models (LLMs) are increasingly applied to real-world scenarios, it becomes crucial to understand their ability to follow multiple instructions simultaneously. To systematically evaluate these capabilities, we introduce two specialized benchmarks for fundamental domains where multiple instructions following is important: Many Instruction-Following Eval (ManyIFEval) for text generation with up to ten instructions, and Style-aware Mostly Basic Programming Problems (StyleMBPP) for…

Energy minimization for skyrmions on planar thin films
We consider an energy functional that arises in micromagnetic and liquid crystal theory on thin films. In particular, our energy comprises a non-convex term that models anti-symmetric exchange as well as an anisotropy term. We devise an algorithm for energy minimization in the continuous case and show weak convergence of a subsequence towards a solution of the corresponding Euler--Lagrange equation. Furthermore, an algorithm for numerical energy minimization is presented. We show empirically th…

Frustrated with failing ID checks, migrants change their names to fit Australian databases
Some migrants are changing names that do not fit standard Anglo-Saxon conventions, in order to avoid identity verification woes.

An approximate history of my amateur phone photography:
1. Really poor photos. Unsavory interest in (low resolution) panoramas.
2. Photos get a little better. Sometimes they're HDRs (I suspect the camera app was set to "auto").
3. A new phone. Higher resolution and a gyroscope.
4. Switching to LineageOS, and therefore to #OpenCamera. HDR enabled unconditionally.
5. HDR does not always come great (compared to the stock Motorola app that doesn't work anymore). I enable saving component photos, so I could try getting a better quality combination using the PC. I never manage that.
6. I start experimenting with exposure correction (combined with HDR). Sometimes I do multiple photos with different "Eves" to choose the best one.
7. A new phone. Finally, given even the gyroscope was failing already.
8. I learn that Pixels have "HDR " that gets activated when you do standard mode photos. For a while I do both standard and HDR photos; also I compare the middle component image with the standard mode image. [https://opencamera.sourceforge.io/help.html#faq]
9. Before I reach any final conclusions, I read "What is HDR, anyway?" I disable HDR entirely, instead I save standard mode (i.e. HDR ) raw images (which presumably aren't affected by HDR ) [https://www.lux.camera/what-is-hdr/]. Not that I ever managed to get anything good out of raws.
10. I discover that I can switch the lens. Today I've made my first photos, switching lens to get optical zoom 💪.

Strain-induced Dynamic Spin-Phonon Coupling in Epitaxial RuO2 Films
Magnetic order parameters in altermagnets can couple to quantized lattice vibration via both piezomagnetic and magnetoelastic effects, leading to the renormalization of phonon dispersion. Here, we demonstrate photo-induced dynamic frequency modulation of THz phonons excited in anisotropically-strained epitaxial RuO2 thin films using ultrafast coherent phonon spectroscopy and time-resolved magneto-optic Kerr effect measurement. A coherent oscillation of a transverse acoustic phonon appears in th…

Really silly dream
I had a really silly #dream recently. I dreamt that my CFL broke. Or more specifically, it kept trying to turn out, successive parts of it were lighting up, then it all went off and tried again. And it looked like it had a bunch of cuts across it, and around these cuts little thunder sparks started appearing, like some kind of STALKER-like anomaly.
I finally flipped the switch, but the anomaly remained, and I wanted to get rid of it in case the sparks could jump onto my hardware and damage something. So I threw a metal bowl towards it, supposing the thunder would jump onto it. While it was flying near the anomaly, it slowed down and started turning back like a boomerang. On top of that, pieces of cat food (don't ask me why I threw a full bowl) were getting out of it and staying in the air levitating. When the bowl reached the floor and started turning again, Mr Ek came close to it and started levitating himself; he was sitting a few centimeters above the floor.
In the middle of all this, I've figured out I should record it. I took a bunch of photos with my phone, before I managed to switch to recording video.
Once I've recorded the fascinating flying bowls and levitating cat food, I needed to go back to discharging the thing. I threw a second metal bowl, and that one started levitating as well. I've figured out that's stupid, and I've found some big ass hammer with a metal end and a wooden handle. I held the end near the lamp to charge it, then tried to find something to discharge it to. I've tried some small stuff like the door handle, but obviously that wasn't sufficient. Finally, I've figured out to use the electricity box, since it is grounded. I held the hammer to it, watching sparks light the semi-darkness; I've recorded that as well.
And that's how much of it I remember.
