Impedance-tuned microwave loop for fast, homogeneous Rabi oscillations of a dense ensemble of NV-diamond electronic spins
Obtaining a high Rabi oscillation frequency homogeneously across a spatially-extended population of nitrogen-vacancy (NV) center electronic spins in diamond is useful for efficient spin-state manipulation of the NV ensemble and in using NVs to detect ensembles of other spin species. Here, we achieve a high, homogeneous Rabi frequency for a dense NV ensemble by enhancing the microwave magnetic fields in the center region of a diamond-coupled planar metallic loop via systematic engineering that i…

Rigidity control of general origami structures
Origami, the traditional paper-folding art, has inspired the modern design of numerous flexible structures in science and engineering. In particular, origami structures with different physical properties have been studied and utilized for various applications. More recently, several deterministic and stochastic approaches have been developed for controlling the rigidity or softness of the Miura-ori structures. However, the rigidity control of other origami structures is much less understood. In…

Si vous avez vu le documenaire ARTE, Bouddhisme la Loi du Silence ou la video résumé de la chaîne Dissecte sur l'OKC, cela soulève pas mal de question, nous avons tenté d'y répondre avec une page dédiée sur notre site : https://chardonsbleus.org/faq

Poszliśmy sobie do restauracji w wiosce rybackiej na małej wyspie - oczywiście bardzo turystyczne miejsce, nie da się ukryć, ale jedzenie mieli super.

Zupa rybna była tak dobra, że żałowaliśmy, że na przystawkę wzięliśmy. Myślałem, że nie lubię zup rybnych, ale chyba wcześniej nie jadłem dobrej. Carpaccio z wieloryba było osobliwe - bardzo dobre, ale jest to niepowtarzalny smak, który bym porównał do dziczyzny z morza. Dorsz świetny, ale potrawka taka se - no wszystko dobrze, ale warzywa…

One-sample survival tests for non-proportional hazards in oncology clinical trial
In oncology, well-powered time-to-event randomized clinical trials are challenging due to a limited number of patients (e.g, pediatric cancers or personalized medicine). Last decade, many one- or two-stage designs for single-arm trials (SATs) have emerged as an alternative to overcome this issue. These designs rely on the one-sample log-rank test (OSLRT) and its modified version (mOSLRT) to compare the survival curves of an experimental and an external control group under the proportional hazar…

Extreme Thermal Insulation in Nano-Bubble Wrap Materials
Achieving ultra-low thermal conductivity under ambient conditions is a fundamental challenge constrained by classical heat transport limits and material design trade-offs. Here, we introduce a new class of nano-bubble wrap architectures that achieve exceptionally low thermal conductivity by integrating nanoscale gas confinement with atomically thin, weakly coupled van der Waals solids. Using scalable patterning of 2D monolayers into periodic nano-bubbles and nano-wrinkles, we construct material…
