I wrote this fun interactive article explaining Isomap, a classic non-linear dimensionality reduction technique. Isomap captures the local similarity structure of data through a graph and computes an embedding that preserves this structure. Check it out! Link below.

Many dimensionality reduction algorithms share a few central principles. 1. Construct a graph that captures the data's local structure 2. Measure "geodesic" distances between points using the graph 3. Project the points to a lower dimension while preserving these distances

#cellbiology #bioart The actin #cytoskeleton (green) is linked to a variety of transmembrane proteins through alpha-actinin (magenta), with such linkages being particularly dense in membrane ruffles and filopodia. As seen at 3 frames/min for 8 min by linear and non-linear structured illumination microscopy (97 and 60 nm resolution, respectively).

Dry Needling: Ultrasound Diagnosis A patient presents with pain along the semitendinosus muscle and a suspected muscle fiber tear. A thigh ultrasound is ordered. Ultrasound reveals multiple linear tracts of increased echogenicity in the proximal third of the semitendinosus muscle, which correlate with a history of dry needling performed 3 days before the radiological study. Dry needling is an invasive technique used in physiotherapy to eliminate painful muscle points (or trigger points) that can develop due to overuse. It is essential not to perform this treatment within 5 days of a diagnostic ultrasound or MRI, as it can hinder or prevent the diagnosis of a muscle injury, especially a grade I injury.

Posted a full preview of this in my discord, here's a snippet! This is the culmination of all the stuff I've been learning the last few months. There's a Daz3d model in there being driven by motion capture data, with a physics driven hair rig and some basic jiggle on the boobs.

SOMEONE FROM TOKYO IS MAPPING BIRD LANGUAGE INTO REAL DATA PATTERNS AND THE VISUALIZATION LOOKS LIKE A NEURAL NETWORK DREAMING Every bird sound - frequency, duration, amplitude and modulation - gets converted into 3D space coordinates and rendered as a cluster of colored points in real time through Deepen AI. A microphone captures the acoustic signal, FFT breaks it down into frequency components from 1 kHz to 8 kHz where most birds communicate, an ML model classifies the pattern and the mapped data hits a graph where each call type gets its own color and position in space. Birds have a vocal repertoire of 5 to 200+ unique signals depending on the species - and every signal carries different information about predators, food, territory and mates that humans simply can't hear. The same technology that decodes bird language detects anomalies in industrial machinery, cardiac rhythms and structural vibrations in buildings - he just trained it on nature first.

My data has been exhausted once again, but this time, my mobile data isn’t sharing as expected since I don’t have a bundle. This means yesterday, my data bundle was being deducted at a rate of 10MB per second, even though my internet speed or the data my device was using wasn’t even up to 2MB per second. Inaccurate deductions!

Mx. Glitter Eyes is out here putting his life “on the line” for the Progress Pride flag. Points at the rainbow like it’s the 101st Airborne. He points to the flag of Hawaii and declares he’d die for it. Points at the Nazi flag like “not only burn.” Points at the American flag as an afterthought, but says he would burn and piss on it. This is the same energy as a guy who gets winded opening a bag of Flamin’ Hot Cheetos declaring he’s ready to die for the cause. Leftism in 2026: non-binary pronouns, Sephora-tier eyeshadow, and cosplaying as a revolutionary from the safety of a hexagonal shelf full of knick-knacks. These people aren’t serious. They’re just loud.

🚨Edmonton: #Khalistani activists in Canada are openly radicalizing young children by parading them in processions where kids perform with swords & chant separatist slogans. This is not cultural celebration — it is pure exploitation, using innocent children as props to push a violent separatist agenda under the guise of a 'Nagar Kirtan'. #cdnpoli
