After some neighbors say they want to be able to drive cars in cycletrack, DC govt replaces it with painted lanes & says basis for action was aesthetics of flexposts.
If the problem is really that flexposts don't look nice, why not replace them with decorative bollards?

D.C. is removing bike lane barriers for the first time, calling them ugly
The move comes as political leaders across the country begin reversing and undoing bike lane plans.

Low-Power Optical Actuation of n-GaAs Cantilevers via Surface Piezoelectric Coupling

Low-Power Optical Actuation of n-GaAs Cantilevers via Surface Piezoelectric Coupling
The mechanical behavior of any semiconductor microstructure is inevitably coupled to light. In the case of micro mechanical resonators (MEMs), carrier generation can affect the quality factor of the resonance through electron-phonon scattering and ohmic losses, but it may also inject energy into the structure and induce movement. Thus, semiconductor MEMs may be regarded as intrinsically optomechanical systems. Here, we report on the optical actuation of a simple-clamped n-GaAs cantilever. This …

Claude Sonnet 4.0 describes the image as: "I can see this is a scene set in what appears to be a futuristic medical facility or laboratory, with clean white walls and advanced-looking equipment visible in the background. The setting has the distinctive sterile, high-tech aesthetic typical of science fiction productions from this era. An elderly man with grey curly hair is seated at what looks like a examination or work table, wearing casual clothing. The scene appears to be from a dramatic mome…

MOMAV: A highly symmetrical fully-actuated multirotor drone using optimizing control allocation
MOMAV (Marco's Omnidirectional Micro Aerial Vehicle) is a multirotor drone that is fully actuated, meaning it can control its orientation independently of its position. MOMAV is also highly symmetrical, making its flight efficiency largely unaffected by its current orientation. These characteristics are achieved by a novel drone design where six rotor arms align with the vertices of an octahedron, and where each arm can actively rotate along its long axis. Various standout features of MOMAV are…

Ilford FP4 E.I. 64 **English Alt Text:** This black-and-white photograph captures a quiet urban scene. In the foreground, there is a sidewalk and a street with visible lane markings. A bench is situated on the sidewalk, positioned against a large wall that appears to be part of a building. The wall has a textured surface and shows signs of wear and tear. The shadows of trees are cast onto the wall, adding a dynamic element to the otherwise static scene. The overall atmosphere is calm and somew…
Ilford FP4 E.I. 64 **English Alt Text:** This black-and-white photograph depicts a stack of construction materials placed in front of a modern building. The materials, which appear to be metal sheets or panels, are neatly bundled and secured with straps. The building behind the materials has a glass facade, reflecting the surrounding environment, including trees and the sky. The image captures a moment of urban development or renovation, with the contrast between the raw construction materials…
Ilford FP4 E.I. 64 **English Alt Text:** This black-and-white image features a close-up view of a modern architectural structure. The photograph is taken from a low angle, capturing the sleek lines and geometric shapes of the building. A curved element, possibly part of a railing or decorative feature, frames the image on the right side. The building's facade is smooth and reflective, with a series of evenly spaced elements that add to its contemporary aesthetic. The contrast between light and…
Ilford FP4 E.I. 64 **English Alt Text:** This black-and-white image captures a person engaged in cleaning or maintenance work on a balcony of a modern building. The individual is silhouetted against the bright background, creating a stark contrast that highlights their activity. The building has a glass facade, and part of it is covered with a protective sheet, possibly for renovation or cleaning purposes. The scene is framed by the railing of the balcony, and the surrounding environment, incl…

Claude Sonnet 4.0 describes the image as: "I can see two people in what appears to be a futuristic setting with green mesh or grid-like walls in the background. One person is wearing an elaborate white outfit with dramatic ruffled or wing-like sleeves and appears to have short dark hair. The other person is wearing what looks like a blue and gray uniform or jacket. The setting has a science fiction aesthetic typical of television productions from that era, with the distinctive green metallic me…

Vib2Move: In-Hand Object Reconfiguration via Fingertip Micro-Vibrations
We introduce Vib2Move, a novel approach for in-hand object reconfiguration that uses fingertip micro-vibrations and gravity to precisely reposition planar objects. Our framework comprises three key innovations. First, we design a vibration-based actuator that dynamically modulates the effective finger-object friction coefficient, effectively emulating changes in gripping force. Second, we derive a sliding motion model for objects clamped in a parallel gripper with two symmetric, variable-fricti…
