#Halfbike #FediBikes #MastoBikes #Cycling

A Halfbike (a compact, three-wheeled stand-up bicycle) is parked on a paved surface near a bush and a large rock in an urban residential area. It features a large front wheel, two smaller rear wheels, and a tall vertical handlebar with the word “halfbike” printed on it. The minimalist frame and upright design reflect its blend of cycling, running, and skiing, intended for full-body workouts or urban commuting.
A cafe table with a pink basket holding a sugar-coated donut on paper, beside a green ceramic mug filled with black coffee. A white and black bicycle helmet rests nearby. Through the window in the background, a Halfbike is parked on cobblestone pavement, partially obscured by green plants.
Scenic waterfront view from the rooftop of the Oslo Opera House. In the foreground, a Halfbike leans against a white stone wall, next to a bin. In the water below is “She Lies” (a glass and steel sculpture resembling a fragmented iceberg). In the background, a large cruise ship is docked at the port, with hills and city buildings visible under clear daylight.
A Halfbike leans against a brick wall on a tiled pavement. A red cylindrical ciggerette bin is is just in front of the bike frame, and a black helmet hangs from the handlebar. The setting includes a black door to the left and a building with large windows and a bench to the right.

Hey friends, sorry to be so silent again. Busy life - but nothing bad.
Just wanted to share this photo with you :
THIS was the narrowest passage ahead. It's just this and around the corner, after this it widens up again. And I can promise: it does not just look narrow - it really IS.
I admit that I thought "ohkay, I did NOT expect that and I hope it won't get worse".
(it didn't and it was fun after all)

In this image, we see a person standing in a dimly lit cave, their gaze fixed on a bright light source in the distance. The cave walls are dark, creating a stark contrast with the person's figure. The dominant colors in the scene are black and brown, with the accent color being a deep shade of brown. The person, identified as the main object in the image, occupies a significant portion of the frame and appears to be captivated by the mysterious light. The setting suggests a sense of exploration…

They had a bunch of abandoned water bottles at the Catherwood Library so I asked the clerk: "I work for an organization founded by Elmo Roper, can I have the bottle with Elmo?" and they gave it to me.

A big ass backpak fills about half the frame, sitting on a desk that I eliminated with an R5 sigil. Strapped to the backpack is a big black water bottle with major dents, a white symbol that looks like an abstract person smiling with hair standing up and a sticker of the Sesame Street character roper in red with a white background and googly eyes and a caption that reads Hydro Flask. Behind that a few prints are partially visible.

Can stellar physics explain GW231123?
The gravitational wave event GW231123 detected by the LIGO interferometers during their fourth observing run features two black holes with source-frame masses of $137^{+22}_{-17} M_\odot$ and $103^{+20}_{-52} M_\odot $ -- well within or above the pair-instability black hole mass gap predicted by standard stellar evolution theory. Both black holes are also inferred to be rapidly spinning ($χ_1 \simeq 0.9$, $χ_2 \simeq 0.8$). The primary object in GW231123 is the heaviest stellar mass black hol…

General Boosted Black Holes: A First Approximation
In this paper we obtain an approximate solution of Einstein field equations which describes a general boosted Kerr-Newman black hole relative to a Lorentz frame at future null infinity. The boosted black hole is obtained from a general twisting metric whose boost emerges from the BMS group. Employing a standard procedure we build the electromagnetic energy-momentum tensor with the Kerr boosted metric together with its timelike Killing vector as the electromagnetic potential. We demonstrate that…

Discrete optimal transport is a strong audio adversarial attack
In this paper, we show that discrete optimal transport (DOT) is an effective black-box adversarial attack against modern audio anti-spoofing countermeasures (CMs). Our attack operates as a post-processing, distribution-alignment step: frame-level WavLM embeddings of generated speech are aligned to an unpaired bona fide pool via entropic OT and a top-$k$ barycentric projection, then decoded with a neural vocoder. Evaluated on ASVspoof2019 and ASVspoof5 with AASIST baselines, DOT yields consisten…

Today has been mainly about stripping down my favourite mountain bike for repainting and renovation.
#BikeTooter

My 2004 Cannondale Jekyll, a lightweight black full suspension mountain bike with a 'lefty' single sided front fork, leaning against a fence in a green field.
The same bike, hanging from my workstand, with its rear wheel, rear triangle, and handlebars removed. The workstand stands in a concreted roadway, with the rusty railings of the old communal cattle management yard behind.
Transporting what's left of the bike down to the bike workshop in the village, on another bike -- the big black cargo bike -- of course. The cargo bike faces the camera, standing on the concrete roadway. The frame and front wheel of the mountain bike lie across its box.
The frame of the mountain bike leans against a bench standing on green grass, while the front fork leg, now detached, lies on the bed and the front wheel, also detached, leans against the other side.

I had an air filter attached to the rear of my #Kombi, and then I realized that I couldn't shift. One of the cords that I had used to secure the hepa filter was on the derailleur. It was an easy thing to fix, but it reminded me just how much I hate derailleurs (and any kind of external gears in general).

Directional Neutrino Bursts from Spinning and Moving Primordial Black Holes
We show that primordial black holes (PBHs) with significant spin and bulk motion produce sharply collimated neutrino bursts from Hawking evaporation, arising from the interplay of spin-induced angular anisotropy and relativistic Doppler boosting. This effect shifts the neutrino spectrum into the multi-GeV to hundreds of GeV range, where atmospheric backgrounds drop steeply, and enhances the flux by orders of magnitude within a narrow forward cone. We compute the full lab-frame neutrino distribu…

The cosmic evolution of obscured star formation, dust properties and production mechanisms, and the prevalence of dust-obscured AGN out to high redshifts are currently some of the hot topics in astrophysics. While much progress has been made in the early days with Spitzer and Herschel, these facilities have not reached the necessary depths to observe the mid-IR light of high-redshift (z > 3) galaxies.

Semi-analytical Study on the Polarized Images of Black Hole due to Frame Dragging
An initially retrograde accretion flow is transformed into a prograde configuration before plunging into the black hole, as a result of the frame-dragging effect induced by the black hole's rotation. The polarized image of a black hole shaped by such an accretion flow manifests three distinctive critical locations: the turning point of the flow's primary image, the polarization-flip location on the image plane, and the position of the primary image corresponding to the flow's actual turning poi…

I needed to bring a few things into the office today, which is always a bit annoying as my back tends to get hot when I cycle with a backpack on. Then I suddenly remembered that #TallBikesArePractical and I have a shit ton of storage space below me.
Look at my little backpack. It looks tiny down there! 🤏 🎒

Looking down at a blue tall bike from the point of view of the rider. It is possible to see the frame of the bike and one hand on the handlebars, along with the riders legs. Below that is a small black backpack strapped to the bottom of the frame.

Black holes and wormholes in Deser-Woodard gravity
The Deser-Woodard gravity is a modified theory of gravity in which nonlocality plays a central role. In this context, nonlocality is consequence of the inverse of the d'Alembertian operator $\square^{-1}$ in the effective action. Here, analytic black hole and wormhole solutions are built in the revised Deser-Woodard theory following a recent approach, where a special tetrad frame simplifies the complicated field equations of the theory. From deviations of the Schwarzschild metric and Reissner-N…

X-ray polarization of reflected thermal emission
X-ray thermal emission is inherent in neutron-star and black-hole X-ray binary systems. Within these systems, it may reflect from optically thick matter, which will create characteristic observable X-ray spectro-polarimetric features. We compute rest-frame reflection spectra and the corresponding energy-dependent linear polarization degree and angle for (un)polarized single-temperature black-body spectra impinging on a partially ionized constant-density optically thick slab. We use a combinatio…

Not-quite-primordial black holes seeded by cosmic string loops
Cosmic strings appear in many well-motivated extensions to the standard model of particle physics. If they exist, an abundant population of compact objects known as cosmic string loops permeate the Universe at all times, providing a secondary source of density perturbations that are large amplitude and non-gaussian in nature. In general, these loops are not stationary in the rest frame of the dark matter, thus their relative velocities will typically seed both spherical and filamentary overdens…

Constraining Cubic Curvature Corrections to General Relativity with Quasi-Periodic Oscillations
We investigate observational constraints on cubic curvature corrections to general relativity by analyzing quasi-periodic oscillations (QPOs) in accreting black hole systems. In particular, we study Kerr black hole solution corrected by cubic curvature terms parameterized by $β_5$ and $β_6$. While $β_6$ corresponds to a field-redefinition invariant structure, the $β_5$ term can in principle be removed via a field redefinition. Nonetheless, since we work in the frame where the accreting matt…

Can Static Black Holes in Massive Gravity Serve as Candidates for Aschenbach-Like Phenomena?

arxiv.org/abs/2507.15563

Can Static Black Holes in Massive Gravity Serve as Candidates for Aschenbach-Like Phenomena?
The Aschenbach effect is widely regarded as a manifestation of two quintessential relativistic features: frame dragging and extreme spacetime curvature. Traditionally associated with rotating geometries, this non-monotonic behavior in orbital angular velocity challenges Newtonian intuition. In our previous work, however, we demonstrated that this velocity irregularity is not exclusive to spinning spacetimes. Specifically, we showed that the presence of a stable minimum in the gravitational pote…

Strong scale-dependence does not enhance the kinematic boosting of gravitational wave backgrounds
Giorgio Mentasti, Carlo R. Contaldi, Marco Peloso
arxiv.org/abs/2507.16901

Strong scale-dependence does not enhance the kinematic boosting of gravitational wave backgrounds
Existing expressions in the literature appear to indicate that Doppler boosting, due to our proper motion with respect to the isotropic frame of the universe, can amplify stochastic gravitational wave backgrounds whose energy spectra exhibit strong scale dependence, for example, those generated by large scalar perturbations in models of primordial black holes or by astrophysical populations with broken power-law behaviour. It has been suggested that this enhancement could increase the signal-to…
