Admissible convergence behavior and mirroring of stagnation in restarted (block) GMRES
In this work, we describe how to construct matrices and block right-hand sides the exhibit a specified restarted block GMRES convergence pattern, such that the eigenvalues and Ritz values at each iteration can be chosen independent of the specified convergence behavior. This work is a generalization of the work in [Meurant and Tebbens, Num. Alg. 2019] in which the authors do the same for restarted non-block GMRES. We use the same tools as were used in [Kubínová and Soodhalter, SIMAX 2020], na…

Homeownership as Life Cycle Goldmine: Evidence from Macrohistory
Should a household buy a home? Using data from 16 developed countries spanning 1870 to 2020, this study provides a resounding affirmative answer. Contrary to popular expert advice, homeownership enhances life cycle wealth by up to 9% and welfare by up to 23%, compared to all-equity investment strategy. Homeownership reduces wealth portfolio risk and improves wealth equality, though it comes at the cost of lower working-life wealth and curtailed financial asset holdings. Gains are heterogeneous:…

Optimal 4-Approximation for the Correlated Pandora's Problem
The Correlated Pandora's Problem posed by Chawla et al. (2020) generalizes the classical Pandora's Problem by allowing the numbers inside the Pandora's boxes to be correlated. It also generalizes the Min Sum Set Cover problem, and is related to the Uniform Decision Tree problem. This paper gives an optimal 4-approximation for the Correlated Pandora's Problem, matching the lower bound of 4 from Min Sum Set Cover.

Nonlinear-linear duality for multipath quantum interference
In quantum optics, the postselection amplitude of a nondegenerate parametric down-conversion (PDC) process is linked to a beamsplitter (BS) via partial time reversal, up to a normalization coefficient which is related to the parametric gain [Proc. Natl. Acad. Sci. USA 117, 33107 (2020)]. A special example where the gain is low is reminiscent of Klyshko's advanced-wave picture in quantum imaging.

Sharp Hardy and spectral gap inequalities on special irreversible Finsler manifolds
The sharpness of various Hardy-type inequalities is well-understood in the reversible Finsler setting; while infinite reversibility implies the failure of these functional inequalities, cf. Kristály, Huang, and Zhao [Trans. Am. Math. Soc., 2020]. However, in the remaining case of irreversible manifolds with finite reversibility, there is no evidence on the sharpness of Hardy-type inequalities. In fact, we are not aware of any particular examples where the sharpness persists. In this paper we p…

Ryugu asteroid research reveals mineral history predating any on Earth
In 2020, the Hayabusa2 uncrewed spacecraft successfully returned small fragments from the near-Earth asteroid Ryugu, providing the first pristine samples from a carbonaceous asteroid. Grains from those samples were studied at the National Synchrotron Light Source II (NSLS-II), revealing new details into the asteroid's composition and origin. This insight could ultimately help answer big questions about how water and organic matter came to exist on early Earth, forming the building blocks of lif…

Threshold-Driven Streaming Graph: Expansion and Rumor Spreading
A randomized distributed algorithm called RAES was introduced in [Becchetti et al., SODA 2020] to extract a bounded-degree expander from a dense $n$-vertex expander graph $G = (V, E)$. The algorithm relies on a simple threshold-based procedure. A key assumption in [Becchetti et al., SODA 2020] is that the input graph $G$ is static - i.e., both its vertex set $V$ and edge set $E$ remain unchanged throughout the process - while the analysis of RAES in dynamic models is left as a major open questi…

In recent years, there has been growing interest in understanding the expressive power of graph neural networks (GNNs) by relating them to logical languages. This research has been been initialised by an influential result of Barceló et al.

As a ``challenging open problem'' they left the question whether full C2 characterises the logical ex…

Using U.S. Equities from 2012 to mid-2025, we design the model using 2012 to 2019 data, and evaluate it out-of-sample from 2020 to 2025 against a sector index built from exchange-traded funds and a static risk-balanced portfolio. Over the test window, the adaptive portfolio compounds wealth by approximately 120 percent, compared with 1…

A Radio-quiet AGN as a candidate counterpart to neutrino event IceCube-200615A
Follow-up observations of neutrino events have been a promising method for identifying sources of very-high-energy cosmic rays. Neutrinos are unambiguous tracers of hadronic interactions and cosmic rays. On June 15, 2020, IceCube detected a neutrino event with an 82.8% probability of being astrophysical in origin. To identify the astrophysical source of the neutrino, we used X-ray tiling observations to identify potential counterpart sources. We performed additional multiwavelength follow-up wi…

On Rota--Baxter operators on finite simple groups of Lie type
Rota--Baxter operators on groups were introduced by L. Guo, H. Lang, Yu. Sheng in 2020. In 2023, V. Bardakov and the second author showed that all Rota--Baxter operators on simple sporadic groups are splitting, i.\,e. they correspond to exact factorizations of groups. In 2024, the authors of the current paper described all non-splitting Rota--Baxter operators on alternating groups. Now we describe Rota--Baxter operators on finite simple exceptional groups of Lie type and projective special li…

Fourier Spectral Method for Nonlocal Equations on Bounded Domains
This work introduces efficient and accurate spectral solvers for nonlocal equations on bounded domains. These spectral solvers exploit the fact that integration in the nonlocal formulation transforms into multiplication in Fourier space and that nonlocality is decoupled from the grid size. As a result, the computational cost is reduced to $O(N\log N)$ for an $N$-point discretization grid. Our approach extends the spectral solvers developed by Alali and Albin (2020) for periodic domains by incor…

When is String Reconstruction using de Bruijn Graphs Hard?
The reduction of the fragment assembly problem to (variations of) the classical Eulerian trail problem [Pevzner et al., PNAS 2001] has led to remarkable progress in genome assembly. This reduction employs the notion of de Bruijn graph $G=(V,E)$ of order $k$ over an alphabet $Σ$. A single Eulerian trail in $G$ represents a candidate genome reconstruction. Bernardini et al. have also introduced the complementary idea in data privacy [ALENEX 2020] based on $z$-anonymity. The pressing question i…

Prediction of sulphate hazes in the lower Venus atmosphere
We study the amount, size distribution and material composition of (sub-)mic aerosol particles in the lower Venus atmosphere < 50 km. Our GGchem phase-equilibrium model predicts metal-chloride and metal-fluoride molecules to be present in the gas over the Venus surface in trace concentrations < 2.E-12, in particular FeCl2, NaCl, KCl and SiF4. Using an improved version of the DiffuDrift model developed by Woitke et al.2020, we find that these molecules deposit to form solid potassium sulphate K2…

Adjacency spectral radius and H-factors in 1-binding graphs
Let $G$ be a graph, and let $H:V(G)\longrightarrow\{\{1\},\{0,2\}\}$ be a set-valued function. Hence, $H(v)$ equals $\{1\}$ or $\{0,2\}$ for any $v\in V(G)$. We let $$ H^{-1}(1)=\{v: v\in V(G) \ \mbox{and} \ H(v)=1\}. $$ An $H$-factor of $G$ is a spanning subgraph $F$ of $G$ such that $d_F(v)\in H(v)$ for each $v\in V(G)$. Lu and Kano showed a characterization for the existence of an $H$-factor in a graph [Characterization of 1-tough graphs using factors, Discrete Math. 343 (2020) 111901]. Let …

PDE-Based Bayesian Hierarchical Modeling for Event Spread, with Application to COVID-19 Infection
We extended the Wikle's Bayesian hierarchical model based on a diffusion-reaction equation [Wikle, 2003] to investigate the COVID-19 spatio-temporal spread events across the USA from Mar 2020 to Feb 2022. Our model incorporated an advection term to account for the intra-state spread trend. We applied a Markov chain Monte Carlo (MCMC) method to obtain samples from the posterior distribution of the parameters. We implemented the approach via the collection of the COVID-19 infections across the st…

psi: Plant Photosystem I excitation energy transfer network (2020)
Weighted directed network of the light-harvesting Photosystem Ι (PSI) of the plant Pisum sativum. The nodes represent chromophores with different identities (i.e. chlorophyll a, chlorophyll b, β-carotene and derivates, lutein, violaxanthin), while edges represent FRET transfer between chromophores. The link directionality connecting nodes in the PSI network depends on the energy levels of the connected chromophores. The…

Invisible Labor, Visible Barriers: The Socioeconomic Realities of Women's Work in Pakistan
We provide a short note on the barriers shaping womens economic opportunities in Pakistan, where female labor force participation remains among the lowest in the world. Recent labor force surveys (2020-21) show a sharp rural-urban divide: rural womens participation is 28 percent compared to 69 percent for rural men, while urban womens participation is 10 percent compared to 66 percent for urban men. Unemployment is higher for women in both rural (7 percent) and urban (16 percent) areas than for…
