Generalized convergence of the deep BSDE method: a step towards fully-coupled FBSDEs and applications in stochastic control
We are concerned with high-dimensional coupled FBSDE systems approximated by the deep BSDE method of Han et al. (2018). It was shown by Han and Long (2020) that the errors induced by the deep BSDE method admit a posteriori estimate depending on the loss function, whenever the backward equation only couples into the forward diffusion through the Y process. We generalize this result to fully-coupled drift coefficients, and give sufficient conditions for convergence under standard assumptions. The…

Fate of dissipative hierarchy of timescales in the presence of unitary dynamics
The generic behavior of purely dissipative open quantum many-body systems with local dissipation processes can be investigated using random matrix theory, revealing a hierarchy of decay timescales of observables organized by their complexity as shown in [Wang et al., Phys.

Here, we analyze how this spectrum evolves when unitary dynamics is present, both for the case of strongly and we…

The Bulk Properties of Isolated Neutron Stars Inferred from the Gravitational Redshift Measurements
The measurements of the bulk properties of most isolated neutron stars (INSs) are challenging tasks. Tang et al.

It builds upon the information-theoretic framework of [Russo and Van Roy, 2015] and, more specifically, on the rate-distortion analysis from [Dong and Van Roy, 2020], where they proved a bound with regret rate of $O(d\sqrt{T \log(T)})$ for the $d$-dimensional linear bandit setting. We focus on bandit problems with a metric action space and, using a chaining argument, we establish new boun…

We find that the polarization, which encodes the magnon spin angular momentum, changes periodically with a frequency that is nonlinear…

Direct numerical simulation of transition under free-stream turbulence and the influence of large integral length scales
Under action of free-stream turbulence (FST), elongated streamwise streaky structures are generated inside the boundary layer, and their amplitude and wavelength are crucial for the transition onset. While turbulence intensity is strongly correlated with the transitional Reynolds number, characteristic length scales of the FST are often considered to have a slight impact on the transition location. However, a recent experiment by Fransson & Shahinfar (2020} shows significant effects of FST scal…

Special counsel urges Supreme Court to reject Trump’s immunity claim

Special counsel Jack Smith on Monday urged the Supreme Court to reject Donald Trump’s “novel and sweeping” claim that he is immune from criminal prosecution on charges of conspiring to overturn the results of the 2020 presidential election.

“The President’s constitutional duty to take care that the laws be faithfully executed does not entail a general right to violate them,” Smith said in his office’s main brie…

Upgrade of NaI(Tl) crystal encapsulation for the NEON experiment
The Neutrino Elastic-scattering Observation with NaI(Tl) experiment (NEON) aims to detect coherent elastic neutrino-nucleus scattering~(CE$ν$NS) in a NaI(Tl) crystal using reactor anti-electron neutrinos at the Hanbit nuclear power plant complex. A total of 13.3 kg of NaI(Tl) crystals were initially installed in December 2020 at the tendon gallery, 23.7$\pm$0.3\,m away from the reactor core, which operates at a thermal power of 2.8\,GW. Initial engineering operation was performed from May 2021…

Hard QBFs for Merge Resolution
We prove the first genuine QBF proof size lower bounds for the proof system Merge Resolution (MRes [Olaf Beyersdorff et al., 2020]), a refutational proof system for prenex quantified Boolean formulas (QBF) with a CNF matrix. Unlike most QBF resolution systems in the literature, proofs in MRes consist of resolution steps together with information on countermodels, which are syntactically stored in the proofs as merge maps. As demonstrated in [Olaf Beyersdorff et al., 2020], this makes MRes quite…

Chained Information-Theoretic bounds and Tight Regret Rate for Linear Bandit Problems
This paper studies the Bayesian regret of a variant of the Thompson-Sampling algorithm for bandit problems. It builds upon the information-theoretic framework of [Russo and Van Roy, 2015] and, more specifically, on the rate-distortion analysis from [Dong and Van Roy, 2020], where they proved a bound with regret rate of $O(d\sqrt{T \log(T)})$ for the $d$-dimensional linear bandit setting. We focus on bandit problems with a metric action space and, using a chaining argument, we establish new boun…

A new type of stellarator divertor: the hybrid stellarator divertor
A new type of stellarator divertor is found. It has features of both a nonresonant divertor (A. Punjabi and A. H. Boozer, Phys. Plasmas 27, 012503 (2020)) as well as a resonant divertor. It has the outermost confining surface with sharp edges and large islands outside the outermost surface. For this reason, we have called it hybrid divertor. This divertor can be configured by adjusting the currents in external coils which produce nonresonant perturbations. We have simulated this divertor using …

Reports: Commanders to sign former first-round pick Noah Igbinoghene
The Washington Commanders are signing cornerback Noah Igbinoghene to a free agent deal, according to multiple reports Sunday. A first-round pick by the Dolphins in 2020, Igbinoghene will be playing for his third team. Miami traded him to the Dolphins last August, and he became a free agent at the end of the 2023 season. He becomes the fourth member of the Cowboys' 2023 roster to move to the rival Commanders since Washington hired Dan Quinn as head coach in February. Quinn was the defensive coor…

A Multi-wavelength Study on A Gamma-ray Bright AGN 1308+326 Using KVN at 22 and 43 GHz
In this paper, we conduct a multi-frequency analysis of the gamma-ray bright blazar 1308+326 from February 2013 to March 2020, using the Korean VLBI Network at 22 and 43 GHz and gamma-ray data from the Fermi Large Area Telescope (LAT). Our findings reveal spectral variations around the 2014 gamma-ray flare, aligning with the shock-in-jet model. A strong correlation is observed between gamma-ray and 43 GHz emissions, with a 27-day lag in the VLBI core light curve, indicating a 50-day delay from …

Magnon kinetic theory of the antiferromagnetic Hanle effect
Motivated by the recently discovered magnonic Hanle effect in an insulating antiferromagnet [Wimmer et al., Phys. Rev. Lett. 125, 247204 (2020)], we develop a spin transport theory based on low-energy waves of antiferromagnetic Néel order. These waves have two polarizations, which we describe in analogy to optics using the Stokes vector on the Poincaré sphere. We find that the polarization, which encodes the magnon spin angular momentum, changes periodically with a frequency that is nonlinear…

Pursuing equitable access to vaccines for the next epidemic
To mitigate the pandemic stemming from COVID-19, numerous nations have initiated extensive vaccination campaigns for their citizens since late 2020. While affluent countries have predominantly received vaccine allocations, fewer doses have been dispatched to nations with lower average incomes. This unequal distribution not only widens the disparity between wealthy and impoverished regions but also prolongs the pandemic, evident in the emergence of new viral variants. Our research delves into th…

An improved calendar ring hole-count for the Antikythera mechanism
We present a new analysis of the positions of holes beneath the calendar ring of the Antikythera mechanism, as measured by Budiselic et al. (2020). We significantly refine their estimate for the number of holes that were present in the full ring. Our $68\%$-credible estimate for this number, taking account of all the data, is $355.24^{ +1.39 }_{ -1.36 }$. If holes adjacent to fractures are removed from the analysis, our estimate becomes $354.08^{ +1.47}_{-1.41}$. A ring of 360 holes is strongly…

Direct numerical simulation of transition under free-stream turbulence and the influence of large integral length scales
Under action of free-stream turbulence (FST), elongated streamwise streaky structures are generated inside the boundary layer, and their amplitude and wavelength are crucial for the transition onset. While turbulence intensity is strongly correlated with the transitional Reynolds number, characteristic length scales of the FST are often considered to have a slight impact on the transition location. However, a recent experiment by Fransson & Shahinfar (2020} shows significant effects of FST scal…

On the sensitivity of computed partial charges toward basis set and (exchange-)correlation treatment
Partial charges are a central concept in general chemistry and chemical biology, yet dozens of different computational definitions exist. In prior work [M. Cho et al., \textit{ChemPhysChem} {\bf 21}, 688-696 (2020)], we showed that these can be reduced to at most three `principal components of ionicity'. The present study addressed the dependance on computed partial charges $q$ on 1-particle basis set and (for WFT methods) $n$-particle correlation treatment or (for DFT methods) exchange-correla…

A moment approach for entropy solutions of parameter-dependent hyperbolic conservation laws
We propose a numerical method to solve parameter-dependent hyperbolic partial differential equations (PDEs) with a moment approach, based on a previous work from Marx et al. (2020). This approach relies on a very weak notion of solution of nonlinear equations, namely parametric entropy measure-valued (MV) solutions, satisfying linear equations in the space of Borel measures. The infinite-dimensional linear problem is approximated by a hierarchy of convex, finite-dimensional, semidefinite progra…

The impact of Covid-19 vaccination in Aotearoa New Zealand: a modelling study
Aotearoa New Zealand implemented a Covid-19 elimination strategy in 2020 and 2021, which enabled a large majority of the population to be vaccinated before being exposed to the virus. This strategy delivered one of the lowest pandemic mortality rates in the world. However, quantitative estimates of the population-level health benefits of vaccination are lacking. Here, we use a validated mathematical model to investigate counterfactual scenarios with differing levels of vaccine coverage in diffe…

We introduce a multiphysics and geometric multiscale computational model, suitable to describe the hemodynamics of the whole human heart, driven by a four-chamber electromechanical model. We first present a study on the calibration of the biophysically detailed RDQ20 activation model (Regazzoni et al., 2020) that is able to reproduce the physiological range of hemodynamic biomarkers. Then, we demonstrate that the ability of the force generation model to reproduce certain microscale mechanisms, …
