thumbing through used records at underground sounds, found b.b. king's very first LP, a 1957 compilation of hit singles from 1951 to 1956. fifteen bucks. wow.
the recording quality is not great to begin with, and it's pretty scratchy after almost seventy years, no skips, though ... oh wait i take that back, still, a real find!

Abstract: We develop here a stochastic framework for modeling and segmenting transient spindle- like oscillatory bursts in electroencephalogram (EEG) signals. At the modeling level, individ- ual spindles are represented as path realizations of a two-dimensional Ornstein{Uhlenbeck (OU) process with a stable focus, providing a low-dimensional stochastic dynamical sys- tem whose trajectories reproduce key morphological features of spindles, including their characteristic rise{decay amplitude envelopes. On the signal processing side, we propose a segmentation procedure based on Empirical Mode Decomposition (EMD) combined with the detection of a central extremum, which isolates single spindle events and yields a collection of oscillatory atoms. This construction enables a systematic statistical analysis of spindle features: we derive empirical laws for the distributions of amplitudes, inter-spindle intervals, and rise/decay durations, and show that these exhibit exponential tails consistent with the underlying OU dynamics. We further extend the model to a pair of weakly coupled OU processes with distinct natural frequencies, generating a stochastic mixture of slow, fast, and mixed spindles in random temporal order. The resulting framework provides a data- driven framework for the analysis of transient oscillations in EEG and, more generally, in nonstationary time series.

Standing up at desk, leaving office, never returning #health

Health Experts Recommend Standing Up At Desk, Leaving Office, Never Coming Back
ROCHESTER, MN—In an effort to help working individuals improve their fitness and well-being, experts at the Mayo Clinic issued a new set of health guidelines Thursday recommending that Americans stand up at their desk, leave their office, and never return. “Many Americans spend a minimum of eight hours per day sitting in an office, but we observed significant physical and mental health benefits in subjects after just one instance of standing up, walking out the door, and never coming back t…

Wow. I've dealt with various toxic personalities in software development, but a good portion of the time those toxic personalities were at least extremely knowledgeable in their (often, very limited) domain.
AI, however, seems to be enabling toxic personalities *who are completely clueless*. Impressive!

Wulff Isoperimetry on Cayley Graphs: Submodular BV, Tempered Følner, and Profile Ratio Bounds
We develop a BV framework on Cayley graphs, which yields a sharp discrete Wulff isoperimetric inequality with the best constant tied to the generating set/stencil $S$, a quantitative $Γ$-convergence of discrete to continuum anisotropic perimeter, and a gauge construction in Heisenberg group that neutralizes shear, yielding an BV+shear identity and scale-sharp compactness. As an application we revisit a question of Gromov (2008) on the ratio between the isoperimetric profile and its greatest …
