welkin (@welkin7@ravenation.club)
@aral@mastodon.ar.al Israel had already declared what it was going to do. This was bound to occur. About baby formula, food and medical supplies, the Palestine authority should step up and handle it. Gaza strip had zero Israel troops prior to 7-Oct-2023. It had hospitals, schools and electricity. Now significant portion of Gaza is rubble and it is crawling with Israeli troops. The loosers are people on both sides. How many classes have children of Gaza missed? Was Oct 7 worth it?

Evolution of QPO During Discovery Outburst of MAXI J1834-021: Estimation of Intrinsic Parameters from Spectro-Temporal Study
The Galactic transient black hole candidate (BHC) MAXI~J1834-021 was detected for the first time by MAXI/GSC on February 05, 2023 and it was active for next $\sim 10$~months. A monotonic evolution of low-frequency QPOs from higher to lower frequencies is observed in the middle-phase of the outburst. We study this evolution of the QPO with the propagating oscillatory shock (POS) model, and it suggests the presence of a receding shock. The POS model fit also estimates the mass of the source to be…

This paper is the sequel to another with the same name (Buttigieg et al., Comput. Methods Funct. Theory, 2023), and is concerned with results of the same type. We deduce a result on the moments of the exit time of Brownian motion from domains whose boundary curve is replaced by a dashed line, and from domains arising from a periodic tiling of the plane. We also give a construction of a type of domain which is similar to a wedge domain, but the behaviour of whose exit time moments answer several…

This answered a question posed by Jiang in 1998 in the negative. In this paper, we first extend the notion of BIP to that of iterations of selfmaps (BIP$_k$), and then demonstrate BIP$_k$ for certain products $M\times N$ of nilmanifolds. Finally, we give characterizations for the Lefschetz number, the Nielsen number, and the minimal number of fixed points of se…

Here we report spectrally resolved line profiles for the majority of detected features and provide information on the variability of these maser components between 2012 and 2023. This includes the first tentative detection of a ($J$,$K$) = (5,2) maser in the interstellar medium and the first tentative detection of a (6,4)…

Change of bifurcation type in 2D free boundary model of a moving cell with nonlinear diffusion
We introduce a 2D free boundary problem with nonlinear diffusion that models a living cell moving on a substrate. We prove that this nonlinearity results in a qualitative of solution behavior compared to the linear diffusion case (Rybalko et al. TAMS 2023), namely the switch between direct and inverse pitchfork bifurcation. Our objectives are twofold: (i) develop a rigorous framework to prove existence of bifurcation and determining its type (subcritical vs. superctitical) and (ii) the deri…

Wide-field Polarization Imaging and Numerical Modeling of the Coma and Tail of Comet C/2023 A3 (Tsuchinshan-ATLAS)
Imaging polarimetry is a well-known method for analysing the structure and composition of cometary dust. Accordingly, comets are classified based on the phase angle dependent degree of linear polarization of their comae. The goal of this study is to examine the size and structure of the dust grains in the coma and in particular in the tail of the bright comet C/2023 A3 (Tsuchinshan-ATLAS) and to infer possible variations. For this purpose, we rely on the method of telescopic wide-field polarime…

Run 2/3 measurement of the muon anomalous magnetic moment by the Muon g-2 experiment at Fermilab
The Muon g-2 experiment at Fermilab seeks to measure the muon magnetic moment anomaly, $a_μ=(g-2)/2$, with a final target precision of 0.14 parts-per-million (ppm). The experiment's initial result, published in 2021 using Run 1 data from 2018, confirmed the previous measurement at Brookhaven National Laboratory with a comparable sensitivity of 0.46 ppm. In 2023, a new result based on Run 2 and Run 3 data, collected in 2019 and 2020, was released. These datasets contain four times the data from…

arxiv.org/abs/2507.05102

A tightness criterion for fragmentations
This note presents a simple criterion for the tightness of stochastic fragmentation processes. Our work is motivated by an application to a fragmentation process derived from deleting edges in a conditioned Galton-Watson tree studied by Berzunza-Ojeda and Holmgren (2023). In that paper, while finite-dimensional convergence was established, the claimed functional convergence relied on Lemma 22 of Broutin and Marckert (2016), which is unfortunately incorrect. We show how our results can correct t…

Energetic ($< 2$ MeV) Ion Environment of the Magnetosphere as measured by ASPEX-STEPS on board Aditya-L1 during its earth-bound phase
During its earth-bound phase of the Aditya-L1 spacecraft of India, the Supra-Thermal and Energetic Particle Spectrometer (STEPS) of the Aditya Solar wind Particle EXperiment (ASPEX) was operated whenever the orbit was above 52000 km during 11-19 September 2023. This phase of operation provided measurements of energetic ions (with energies 0.1-2 MeV) in the magnetosphere, magnetosheath, and interplanetary medium. Three interplanetary coronal mass ejections (ICME) hit the magnetosphere during thi…

Near-Optimal Nonconvex-Strongly-Convex Bilevel Optimization with Fully First-Order Oracles
In this work, we consider bilevel optimization when the lower-level problem is strongly convex. Recent works show that with a Hessian-vector product (HVP) oracle, one can provably find an $ε$-stationary point within ${\mathcal{O}}(ε^{-2})$ oracle calls. However, the HVP oracle may be inaccessible or expensive in practice. Kwon et al. (ICML 2023) addressed this issue by proposing a first-order method that can achieve the same goal at a slower rate of $\tilde{\mathcal{O}}(ε^{-3})$. In this pap…

Secure Multi-Key Homomorphic Encryption with Application to Privacy-Preserving Federated Learning
Multi-Key Homomorphic Encryption (MKHE), proposed by Lopez-Alt et al. (STOC 2012), allows for performing arithmetic computations directly on ciphertexts encrypted under distinct keys. Subsequent works by Chen and Dai et al. (CCS 2019) and Kim and Song et al. (CCS 2023) extended this concept by proposing multi-key BFV/CKKS variants, referred to as the CDKS scheme. These variants incorporate asymptotically optimal techniques to facilitate secure computation across multiple data providers. In this…

Suspense and Surprise in European Football
We propose utilizing match-level suspense and surprise - which capture the entertainment utility created by competitive balance and outcome uncertainty for sports spectators - as alternative policy targets for league organizers and managers. Through simulations, we derive a benchmark range for suspense and surprise based on a perfectly balanced match before analyzing over 25,000 men's matches (2010/11-2023/24) and 725 women's matches (2023/24) from Europe's top football leagues. Our findings re…

Temperature Sensitivity of Residential Energy Demand on the Global Scale: A Bayesian Partial Pooling Model
This paper contributes to the limited literature on the temperature sensitivity of residential energy demand on a global scale. Using a Bayesian Partial Pooling model, we estimate country-specific intercepts and slopes, focusing on non-linear temperature response functions. The results, based on data for up to 126 countries spanning from 1978 to 2023, indicate a higher demand for residential electricity and natural gas at temperatures below -5 degrees Celsius and a higher demand for electricity…

This walk is defined as the sum of a sequence of independent steps, where each step goes in one of the four possible directions with equal probability, and the size of the $n$th step is $a_n$ where $\{a_n\}$ is a given sequence of positive …
