Zhu on AI/AGI: 'A sign of true intelligence... is the ability to reason towards a goal with minimal inputs ... a “small data, big task” approach, compared with the “big data, small task” approach employed by large language models like ChatGPT. AGI... is characterised by qualities such as resourcefulness in novel situations, social and physical intuition, and an understanding of cause and effect. Large language models... will never achieve this.'

Sorry for posting so many YouTube videos but this is great and geeky: a video essay about "Akira elevators", those platforms that travel horizontally and vertically at the same time.

They are an awesome design but a bit like mechas they are futuristic tools that feel incredibly dangerous to build as a means to transport humans.

Enhancing the sensitivity of neutrinoless double beta decays via combined multi-transition analysis
Next-generation neutrinoless double-beta ($0νββ$) decay experiments, with projected half-life sensitivities approaching $10^{28}$ years, aim to fully probe the parameter space associated with the inverted neutrino mass ordering. However, this discovery potential remains uncertain, as it depends sensitively on the nuclear matrix element, which exhibits significant model dependence. In this work, we propose a novel strategy to enhance experimental sensitivity by performing a combined analysis …

A novel method of half-life determination for highly charged ions based on isochronous mass spectrometry
The lifetime of the isomeric state in fully stripped 94Ru44+ ions has been measured using isochronous mass spectrometry (IMS) at the experimental Cooler Storage Ring (CSRe) of the Heavy Ion Research Facility in Lanzhou (HIRFL). Previously, the isomeric lifetime was determined by analyzing the decay time points of individual decay events. In this paper, we present a novel approach to determine the isomeric lifetime based on the survival time of ions obtained from IMS. The survival lifetimes of t…

Precise Measurement of $^{216}$Po Half-life with Exact Parent-daughter Pairing in PandaX-4T
We report a precise measurement of $^{216}\rm Po$ half-life using the PandaX-4T liquid xenon time projection chamber (TPC). $^{220}\rm Rn $, emanating from a $^{228}\rm Th $ calibration source, is injected to the detector and undergoes successive $α$ decays, first to $^{216}\rm Po$ and then to $^{212}\rm Pb$. PandaX-4T detector measures the 5-dimensional (5D) information of each decay, including time, energy, and 3-dimensional positions. Therefore, we can identify the $^{220}\rm Rn $ and $^{21…

Half-life Measurements of Highly Charged Radioisotopes by Nuclear Recoil in a Penning Trap
We present a novel method for measuring the half-life of highly charged radioisotopes by non-destructive nuclear recoil detection in a Penning ion trap. A specific emphasis is placed on $\rm ^7Be^{3+}$, which plays a crucial role in stellar evolution and the production of solar neutrinos. The determination of the half-life is necessary to constrain the free electron capture rate in the solar environment, but is difficult to measure by existing techniques. Simulations of the sympathetic cooling …

Quantifying neutron-proton interactions in $N=51$ isotones: from NEEC candidate $^{93}$Mo to $^{99}$Cd
We present a shell-model analysis of $N=51$ isotones, $^{93}$Mo, $^{95}$Ru, $^{97}$Pd, and $^{99}$Cd, to quantify the role of neutron-proton interactions in shaping the location and half-life of isomeric states. The study is motivated by the anomalous behavior of the ${21/2}^+$ isomeric state in $^{93}$Mo, a prominent candidate for nuclear excitation by electron capture (NEEC), which misses an $E2$ decay branch due to a higher-lying ${17/2}^+$ state and instead proceeds via a long-lived $E4$ is…

Sentiment Feedback in Equity Markets: Asymmetries, Retail Heterogeneity, and Structural Calibration
We study how sentiment shocks propagate through equity returns and investor clientele using four independent proxies with sign-aligned kappa-rho parameters. A structural calibration links a one standard deviation innovation in sentiment to a pricing impact of 1.06 basis points with persistence parameter rho = 0.940, yielding a half-life of 11.2 months. The impulse response peaks around the 12-month horizon, indicating slow-moving amplification. Cross-sectionally, a simple D10-D1 portfolio earns…

Now that I’m almost certainly past the half-way point of my life, I’ve realized that many things I used to care about matter little to me. Tech is getting worse in most ways, few new movies interest me, most online spaces are not enjoyable to me. What I am bummed about not getting to experience,though, is meeting new, wonderful generations - and especially not getting to hear their music. Because some of the new bands out there are just *wild*, and I love it so, so much.

Acceleration and Transport of the Unstable Cosmic-ray Isotope $^{60}$Fe in Supernova-Enriched Environments
The unstable isotope $^{60}$Fe, with a half-life of 2.6 million years, is produced primarily in supernova explosions. The observed presence of $^{60}$Fe in cosmic rays and its detection in deep-sea crusts and sediments suggest two possible scenarios: either the direct acceleration of $^{60}$Fe from supernova ejecta or its enrichment in the circumstellar material surrounding supernova progenitors, which indicates cosmic ray production in clusters of supernovae. Focusing on the latter scenario, w…

Machine Learning-Driven High-Precision Model for $α$-Decay Energy and Half-Life Prediction of superheavy nuclei
Based on Extreme Gradient Boosting (XGBoost) framework optimized via Bayesian hyperparameter tuning, we investigated the α-decay energy and half-life of superheavy nuclei. By incorporating key nuclear structural features-including mass number, proton-to-neutron ratio, magic number proximity, and angular momentum transfer-the optimized model captures essential physical mechanisms governing $α$-decay. On the test set, the model achieves significantly lower mean absolute error (MAE) and root mea…

Half-life of $^{136}$Xe for neutrinoless double-$β$ decay calculated with effective axial-vector current coupling unified for two-neurtino and neutrinoless double-$β$ decay modes
The upper limit on the mass of the Majorana neutrino, extracted from the limits on the nonobservation of the neutrinoless double-$β$ ($0νββ$) decay, is hampered by uncertainties in the matrix elements of the transition operators. Recently, we have shown that the values of the effective axial-vector current coupling constants ($g_A^\mathrm{eff}$) for the $0νββ$ and the two-neutrino double-$β$ decays are close. This striking result was obtained for the first time by including vertex corre…

Universal Effective Charges in the $sd$ and $fp$ Shells
The 247-keV state in $^{54}$Sc, populated in the $β$ decay of $^{54}$Ca, is reported here as a nanosecond isomer with a half-life of 26.0(22) ns. The state is interpreted as the $1^+$ member of the $πf_{7/2}\otimesνf_{5/2}$ spin-coupled multiplet, which decays to the $3^+,πf_{7/2} \otimes νp_{1/2}$ ground state. The new half-life corresponds to a pure $E2$ transition with a strength of 1.93(16) W.u., providing the most precise, unambiguous $B(E2)$ value in the neutron-rich $fp$ region to d…

The results indicate that incorporating nonlocal effects significantly impacts half-life calculations, while the BNN method substantially improves prediction accuracy and demonstrates strong extrapolation capabilities. Using Shapley Additive Explanations (SHAP), we conducted a quantitative comparison among the four input feature parameters in the BNN, …
