It was almost the witching hour, so most people in this beach community are home and in bed. I was out #running and came across two big packs of teenagers, both of whom had someone with the stones to give me the “good evening, sir” treatment. Full on Eddie Haskell delivery. 😂
They are, of course, way too young to know about Eddie Haskell. What is their generational equivalent?
Anyway, t…

I don’t know what this flowering tree is, but it smelled wonderful. The scene is looking up past the tree canopy into the dark. Ight sky, mostly cloudy and illuminated from a mostly full moon.

My running stats: 5.11 km in 36:45 for an average pace of 7:11/km

RadProPoser: A Framework for Human Pose Estimation with Uncertainty Quantification from Raw Radar Data
Radar-based human pose estimation (HPE) provides a privacy-preserving, illumination-invariant sensing modality but is challenged by noisy, multipath-affected measurements. We introduce RadProPoser, a probabilistic encoder-decoder architecture that processes complex-valued radar tensors from a compact 3-transmitter, 4-receiver MIMO radar. By incorporating variational inference into keypoint regression, RadProPoser jointly predicts 26 three-dimensional joint locations alongside heteroscedastic al…

Testing Dark Matter with Generative Models for Extragalactic Stellar Streams
Upcoming ground and space-based surveys are poised to illuminate low surface brightness tidal features, providing a new observable connection to dark matter physics. From imaging of tidal debris, the morphology of stellar streams can be used to infer the geometry of dark matter halos. In this paper, we develop a generative approach, X-Stream, which translates stream imaging into constraints on the radial density profile of dark matter halos--from the inner region out to the virial radius. Using…

X-ray reverberation modelling of the observed UV/optical power spectra of quasars
Over the past decade, a significant amount of effort has been put into investigating the ultraviolet (UV) and optical variability of active galactic nuclei (AGNs). Comprehensive studies of intensive multi-wavelength monitoring and surveys of local and high-redshift AGNs have shown that X-ray illumination of AGN accretion discs is a potential explanation for the observed variability. Our main objective is to study the UV/optical power spectra of AGNs under the assumption of X-ray reverberation a…

Good morning from Harlem
#Photography #GoodMorning #Sunrise #NYC

Looking through an arched window two-and-a-half hours after sunrise the sun is just left of center in the window, shining directly into the lens, creating a diagonal lens flare and illuminating the dirt and scratches on the glass. The sky is robin egg blue and cloudless. Pointed roofs of Harlem brownstones are silhouetted across the street, and a taller apartment building can be seen in the distance. The green tops of two trees are on the bottom and right.

Enhancing Spectroscopy and Microscopy with Emerging Methods in Photon-Correlation and Quantum Illumination
Quantum optics has driven major advances in our ability to generate and detect correlations between individual photons. Its principles are now increasingly translated into nanoscale characterization techniques, enhancing spectroscopy, microscopy, and metrology. In this Review, we highlight rapid progress in the field driven by advances in single-photon detectors and quantum light sources, including time-resolved single-photon counting cameras, superconducting nanowire detectors, and increasingl…

Optical appearance of Schwarzschild black holes with optically thin and thick accretion disks at various inclination angles
In this paper, we systematically investigate the optical appearance of a Schwarzschild black hole illuminated by three geometrically thin accretion disk models under varying observational inclination angles. Based on the geometric relationship between the black hole and observer, we first divide the accretion disk into co-side and counter-side semi-disks. Subsequently, we analyze their differences in photon orbit distributions, transfer functions, and received intensities. Our results reveal di…

I set my watch to notify on zone 2 borders and “ran” 🙄 for an hour. Early on, it felt like I was constantly roofing it, but as I got deeper into it, everything seemed to settle. I’m going to try to stay with it, but I don’t know if I can intentionally go so slowly for weeks and weeks.
Saw my fox buddy on the drive home.
