A characterization on trees $T$ with $m(T, λ)=p(T)-2$
Let $m(G,λ)$ be the multiplicity of an eigenvalue $λ$ of a connected graph $G$. Wang et al. [Linear Algebra Appl. 584(2020), 257-266] proved that for any connected graph $G\neq C_n$, $m(G, λ) \leq 2c(G) + p(G) -1$, where $c (G) = |E(G)| - |V (G)| + 1$ and $p(G)$ are the cyclomatic number and the number of pendant vertices of $G$, respectively. In the same paper, they proposed the problem to characterize all connected graphs $G$ with eigenvalue $λ$ such that $m(G, λ) =2c…

Scaling of high-Rayleigh-number convection based on internal convective boundary layer
We propose a phenomenological model for thermal convection at high Rayleigh numbers. It hypothesizes existence of a high-Reynolds-number turbulent boundary layer near each horizontal plate, which is shown to be convective. The convective logarithmic friction law of Tong and Ding (2020) is used to relate the large-scale velocity to the induced friction velocity. The predicted scaling relations of the Nusselt ($Nu$) and Reynolds numbers ($Re$) on the Rayleigh number ($Ra$) do not have a power law…

Republican strategists expect most of the party’s primary voters to support Mr. Trump in the general election, pointing to exit polls that found that 4 in 10 of Ms. Haley’s voters in New Hampshire and South Carolina had backed Mr. Biden in 2020.

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…

Quantifying the Bulk Density of Southern Delta Aquariid Meteoroids: Insights from the Canadian Automated Meteor Observatory

Our modelling interprets these observations as evidence for equal masses of compact grains embedded in a porous, low density matrix. The average bulk density of SDA…

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.

However, in that work, the authors only considered the constraints on the EoS from nuclear experiments/theories and the gravitational wave data of GW17…

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…

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 …

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…

Instantons, fluctuations and singularities in the supercritical stochastic nonlinear Schroedinger equation
Recently, Josserand et al. proposed a stochastic nonlinear Schroedinger model for finite-time singularity-mediated turbulence [Phys. Rev. Fluids 5, 054607 (2020)]. Here, we use instanton calculus to quantify the effect of extreme fluctuations on the statistics of the energy dissipation rate. While the contribution of the instanton alone is insufficient, we obtain excellent agreement with direct simulations when including Gaussian fluctuations and the corresponding zero mode. Fluctuations are cr…
