An unconditional lower bound for the active-set method in convex quadratic maximization
We prove that the active-set method needs an exponential number of iterations in the worst-case to maximize a convex quadratic function subject to linear constraints, regardless of the pivot rule used. This substantially improves over the best previously known lower bound [IPCO 2025], which needs objective functions of polynomial degrees $ω(\log d)$ in dimension $d$, to a bound using a convex polynomial of degree 2. In particular, our result firmly resolves the open question [IPCO 2025] of whe…

Revisiting thermal transport in CuCl: First-principles calculations and machine learning force fields
Accurate prediction of lattice thermal conductivity ($κ_l$) in strongly anharmonic materials requires renormalized interatomic force constants (IFCs) and appropriate incorporation of diagonal and off-diagonal contributions and higher-order scattering. We investigate CuCl, a highly anharmonic system with a simple zincblende structure and ultralow $κ_l$. Our calculations, including IFC renormalization and four-phonon scattering, show excellent agreement with the experiment, underscoring the cri…

ADI / Linear Tech LTC4367 power protection controller, from one of my failed 48V IBC designs that blew up from inductive spikes when I applied power.
I didn't do extensive circuit analysis but it looks like one particular net is blown out in several places. Guessing this is the same pin that cratered on the package.
Besides the damage, some other features of interest:
* Colored fringes on large top metal features. Maybe spin-on glass top metal or something.
* The LT…

Intelligent Virtual Sonographer (IVS): Enhancing Physician-Robot-Patient Communication
The advancement and maturity of large language models (LLMs) and robotics have unlocked vast potential for human-computer interaction, particularly in the field of robotic ultrasound. While existing research primarily focuses on either patient-robot or physician-robot interaction, the role of an intelligent virtual sonographer (IVS) bridging physician-robot-patient communication remains underexplored. This work introduces a conversational virtual agent in Extended Reality (XR) that facilitates …

Latitudinal dependence of the solar wind during periods of high and low activity through interplanetary scintillation
We present a study of the solar wind over different periods of the solar cycle, specifically focussing on the minimum between solar cycles 24 and 25, and the active, ascending phase of solar cycle 25. With the use of interplanetary scintillation (IPS) data taken by the Murchison Widefield Array (MWA) from mid-2019 and early 2023, we have sampled over a wide range of solar latitudes and elongations, probing a large section of the surrounding heliosphere from $\sim$90 to 140R$_\odot$. The MWA obs…

Analysis: YC picked just four Indian startups in 2024 vs. 66 in 2021, amid a growing trend of startups shifting their parent entities to India for domestic IPOs (The Economic Times)
https://economictimes.…

From 66 to 4: Why Y Combinator backed fewer Indian startups in 2024
Y Combinator's selection of Indian startups has decreased significantly. This decline is attributed to factors like YC's US incorporation requirement and the rise of domestic IPOs. Indian startups are shifting focus to local funding options. They find domestic markets favorable for listing. YC is also prioritizing AI-focused startups. This shift impacts Indian participation. Domestic capital is growing with regulatory support.
