Anchored Implication & Event-Indexed Fixed Points in Hilbert Spaces: Uniqueness and Quantitative Rates
We develop a synthesis of orthomodular logic (projections as propositions) with operator fixed-point theory in Hilbert spaces. First, we introduce an anchored implication connective $A \Rightarrow^{\mathrm{comm}}_{P} B$, defined semantically so that it is true only when either $A$ is false or else $A$ is true and $B$ is true in a ''commuting'' context specified by a fixed nonzero projection $P$. This connective refines material implication by adding a side condition $[E_B,P]=0$ (commutation of …

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).

Speaking of cursed USB...
What's the most cursed USB thing you have personally had a hand in creating (whether as an actual product or a one-off personal project or prototype)?
For me, it's probably this 4-port hub with male mini-B connectors (yes mini, not micro or C), intended to mate backplane-style directly to small devkits without using a cable.
The connector was incredibly hard to source because ~nobody ever made USB devices with PCB mount (rather than cable m…

I was late to pick my daughter up from camp because #NYCParks closed a huge portion of Corona-Meadows Flushing Park. Apparently for some kind of music festival. There was, of course, no bike detour.

Analysis of the semileptonic decays $Λ_b\toΛ_cl\barν_l$ and $Ξ_b\toΞ_cl\barν_l$ in QCD sum rules
In this article, the electroweak transition form factors of $Λ_b\toΛ_c$ and $Ξ_b\toΞ_c$ are analyzed within the framework of three-point QCD sum rules. In phenomenological side, all possible couplings of interpolating current to hadronic states are considered. In QCD side, the perturbative part and the contributions of vacuum condensates up to dimension 8 are also considered. With the calculated form factors, we study the decay widths and branching ratios of semileptonic decays $Λ_b\toΛ_c…

Emulating Global 21 cm Cosmology Observations from the Lunar Far Side to Achieve Quick and Reliable Physical Constraints
Efforts are underway to measure the global 21 cm signal from neutral hydrogen, which is a powerful probe of the early universe, using NASA radio telescopes on the far side of the Moon. Physics-based models of the signal are computationally expensive to perform Bayesian multi-parameter inferences, for which we have developed novel, publicly-available neural network emulators utilizing a Long Short-Term Memory (LSTM) network and a Kolmogorov-Arnold Network (KAN). $\texttt{21cmLSTM}$ is currently …

The on-shell action of supergravity & the B-side of TsT and single-trace $T\bar T$

The on-shell action of supergravity & the B-side of TsT and single-trace $T\bar T$
We propose boundary terms for the action of the NS sector of supergravity on $M_3 \times S^3 \times T^4$ spacetimes -- where $M_3$ is an AdS$_3$ or a linear dilaton background -- that render the Brown-York stress tensor and the on-shell action finite. For AdS$_3$ backgrounds, we show that the on-shell action yields a free energy with chemical potentials determined by the $B$-field. TsT (T-duality + shift + T-duality) transformations of these backgrounds generate classes of linear dilaton backgr…

Modeling of convective cells, turbulence, and transport induced by a radio-frequency antenna in the tokamak boundary plasma
The edge turbulence model Hermes (Dudson et al., 2017 Plasma Phys. Control. Fusion 59 05401) is set up for plasma boundary simulations with an RF antenna, using parameters characteristic of a tokamak edge. Cartesian slab geometry is used with thin plate limiters representing the ICRF antenna side-wall limiters. Ad-hoc DC electric biasing of the limiters, motivated by calculations with VSim (Nieter et al., J. Comput. Phys. 196, 448 (2004)), represents an induced RF sheath rectified potential in …

I rode on this street (15th Ave NE) 1000s of times with no bike lane, when I used to live on 16th Ave NE. It sucked. I pointed out that drivers only really parked on one side of the street. The city had a plan to repave and add a protected bike lane, but it was delayed for years due to, of all things, "natural gas" pipe expansions. I moved to NYC before they started the project.
It looks SO GOOD, and just as I predicted, the parking is not overloaded despite being on only one…

Hydrodynamic interactions of low-aspect-ratio oscillating panels in a tip-to-tip formation

Hydrodynamic interactions of low-aspect-ratio oscillating panels in a tip-to-tip formation
The vertical, tip-to-tip arrangement of neighboring caudal fins, common in densely packed fish schools, has received much less attention than staggered or side-by-side pairings. We explore this configuration using a canonical system of two trapezoidal plates (aspect ratio AR = 1.2) that pitch about their leading edges while heaving harmonically at a Strouhal number St = 0.45 and a reduced frequency k = 2.09. Direct numerical simulations based on an immersed-boundary method are conducted over a …

$k$-Positive Maps: New Characterizations and a Generation Method
We study $k$-positive linear maps on matrix algebras and address two problems, (i) characterizations of $k$-positivity and (ii) generation of non-decomposable $k$-positive maps. On the characterization side, we derive optimization-based conditions equivalent to $k$-positivity that (a) reduce to a simple check when $k=d$, (b) reveal a direct link to the spectral norm of certain order-3 tensors (aligning with known NP-hardness barriers for $k

Rate-Distortion-Perception Trade-off with Strong Realism Constraints: Role of Side Information and Common Randomness
In image compression, with recent advances in generative modeling, existence of a trade-off between the rate and perceptual quality has been brought to light, where the perceptual quality is measured by the closeness of the output and source distributions. We consider the compression of a memoryless source sequence $X^n=(X_1, \ldots, X_n)$ in the presence of memoryless side information $Z^n=(Z_1, \ldots, Z_n),$ originally studied by Wyner and Ziv, but elucidate the impact of a strong perfect re…

glass: ordered set data structure for client-side order books
The "ordered set" abstract data type with operations "insert", "erase", "find", "min", "max", "next" and "prev" is ubiquitous in computer science. It is usually implemented with red-black trees, $B$-trees, or $B^+$-trees. We present our implementation of ordered set based on a trie. It only supports integer keys (as opposed to keys of any strict weakly ordered type) and is optimized for market data, namely for what we call sequential locality. The following is the list of what we believe to be …

Somehow we made this part of the Queensboro Bridge worse. This is a 3-4ft wide two-way bike lane. There's so much wrong with this, from the metal manhole cover taking up almost the entire width of the bike lane, to the MUTCD-violating usage of sharrows, to those shitty rumble strip/speed bump things THAT ARE LOOSE.

Empirical cross-system meta-analysis of long-term transmission grid evolution
The potential of grid-side flexibility, the latent ability to reconfigure transmission network topology remains under-used partly because of the lack of empirical studies on how real-world grids evolve.

Noise Reinstates Collapsed Populations: Stochastic Reversal of Deterministic Extinction
Conventional wisdom suggests that environmental noise drives populations toward extinction. In contrast, we report a paradoxical phenomenon in which stochasticity reverses a deterministic tipping point, thereby preventing collapse. Using a hybrid model that integrates logistic growth with a density-triggered sigmoidal collapse, we uncover a striking reversal: deterministic fragility on one side, and stochastic rescue under weak noise on the other. Our analysis demonstrates that noise disrupts t…

Nuclear modification factor $I_{AA}$ in $AA$ collisions at RHIC and LHC energies in scenarios with and without quark-gluon plasma formation in $pp$ collisions

Nuclear modification factor $I_{AA}$ in $AA$ collisions at RHIC and LHC energies in scenarios with and without quark-gluon plasma formation in $pp$ collisions
We calculate the away-side hadron-triggered modification factor $I_{AA}$ in $AA$ collisions at RHIC and LHC energies for scenarios with and without quark-gluon plasma formation in $pp$ collision. We find that for both scenarios theoretical results for $I_{AA}$ agree well with the available data for 2.76 TeV Pb+Pb and 0.2 TeV Au+Au collisions. We make predictions for $I_{AA}$ in 7 TeV O+O collisions that are planned at the LHC. Our results show that measuring $I_{OO}$ in the whole centrality int…
