Neutrino transition dipole moments in light of the KM3NeT event

Neutrino transition dipole moments in light of the KM3NeT event
In 2023, KM3NeT observed the highest energy neutrino seen to date. The most probable estimate places the energy of the neutrino at an extreme value of 220 PeV, and energies up to 2.6 EeV are contained in the $90\%$ probability interval. Even though the source of the signal cannot be ascertained with the available data, this observation already opens unique possibilities to test new physics. Here, we study the implications for the transition magnetic dipole portal connecting active and sterile n…

Analyzing the Performance of a 2.72kWp Rooftop Grid tied Photovoltaic System in Tarlac City, Philippines
Residential and industrial areas are using rooftop grid-tied Photovoltaic (PV) systems, which are becoming increasingly popular. This is because solar energy reduces electrical consumption and provides free energy, while also lowering carbon emissions to create a more sustainable environment. This paper aims to analyze the 2.72kW p rooftop grid-tied PV system performance between 2020 and 2023 in Tarlac City, Philippines. The PV generated yearly is measured by Array Yield (YA), Reference Yield (…

In early 2023, Paul Newby, the Republican chief justice of North Carolina’s Supreme Court,
gave the state and the nation a demonstration of the stunning and overlooked power of his office. 
The previous year, the court — then majority Democrat — had outlawed partisan gerrymandering in the swing state.
Over Newby’s vehement dissent, it had ordered independent outsiders to redraw electoral maps that the GOP-controlled legislature had crafted to conservatives’ advantage.

God’s Chief Justice
Paul Newby, a born-again Christian, has turned his perch atop North Carolina’s Supreme Court into an instrument of political power. Over two decades, he’s driven changes that have reverberated well beyond the borders of his state.

A Note on Conjectures of Gullerud, Johnson, and Mbirika
In 2023, Gullerud, Johnson, and Mbirika presented results on their study of certain tridiagonal real symmetric matrices. As part of their work, they studied the roots to nonhomogeneous equations related to characteristic polynomials of adjacency matrices for path graphs. They showed that a subset of these polynomials give a Fibonacci number when evaluated at the imaginary unit, leading them to make several intriguing conjectures. In this work, we further explore their conjectures regarding the …

Manche der von der Google-KI auf die Frage nach Literaturhinweisen gegebenen Antworten schaffen es, mich zu verblüffen, weil es sich eben nicht um "Halluzinationen" handelt; zB existiert der auf die Frage "Gibt es Publikationen zur Bedeutung des Suseok im Film Parasite?" angegebene Artikel mit dem Titel "Using Parasite’s Scholar’s Stone (水石) in a Critical Race Decoding of Racism and Class" tatsächlich.

Using Parasite’s Scholar’s Stone (水石) in a Critical Race Decoding of Racism and Class
The ‘Scholar’s Stone’ (Suseok수석 水石) which is used as an extensive and pervasive motif in Bong Joon-ho’s 2019 film reveals a good deal of what the concept of ‘intersectionality’ in Critical Race Theory (CRT) seeks to uncover. The Scholar’s Stone functions also as a prism to see refracted through the movie the various hues and colors of Confucian culture still present in contemporary Korea, and these in turn can be further analyzed using aspects of CRT. To ground this thesis…

Measurement of coherent exclusive $J/ψ\toμ^+μ^-$ production in ultraperipheral Pb+Pb collisions at $\sqrt{s_{\textrm{NN}}}=5.36$ TeV with the ATLAS detector
The ATLAS experiment has performed a measurement of coherent exclusive $J/ψ\toμ^+μ^-$ production in ultraperipheral Pb+Pb collisions at $\sqrt{s_{\textrm{NN}}}=5.36$ TeV. The data was recorded at the Large Hadron Collider (LHC) during 2023, and corresponds to an integrated luminosity of 78 $μ$b$^{-1}$. Exclusive $J/ψ$ candidates were selected with a dedicated track-sensitive trigger based on the ATLAS transition radiation tracker. The analysis involves reconstruction of the dimuon invarian…

Dynamical Excitation as a probe of planetary origins
We present a set of numerical simulations of the dynamical evolution of compact planetary systems migrating in a protoplanetary disk whose inner edge is sculpted by the interaction with the stellar magnetic field, as described in Yu et al. (2023). We demonstrate that the resulting final distribution of neighbouring planet period ratios contains only a small surviving fraction of resonant systems, in accordance with observations. The resulting planetary architectures are largely in place by the …

Nearly Optimal Bounds for Stochastic Online Sorting
In the online sorting problem, we have an array $A$ of $n$ cells, and receive a stream of $n$ items $x_1,\dots,x_n\in [0,1]$. When an item arrives, we need to immediately and irrevocably place it into an empty cell. The goal is to minimize the sum of absolute differences between adjacent items, which is called the \emph{cost} of the algorithm. It has been shown by Aamand, Abrahamsen, Beretta, and Kleist (SODA 2023) that when the stream $x_1,\dots,x_n$ is generated adversarially, the optimal cos…

New inequality indicators for team ranking in multi-stage female professional cyclist races
Cycling competition is highly interesting since the team ranking is based on the best performance of some subset of team members. The paper develops new inequality indicators, a methodology to construct them, and numerical illustrations allowing to provide operative arguments in their favor. The numerical illustrations subsequently deal with hierarchical ranking indicators of (female) cyclist teams, competing in multi-stage races. For the illustration, the 2023 editions of the most famous long …

We study three extraordinarily bright X-ray flares originating from Cyg X-1 seen on 2023 July 10 detected with INTEGRAL. The flares had a duration on the order of only ten minutes each, and within seconds reached a 1-100 keV peak luminosity of $1.1-2.6\times10^{38}$ erg/s. The associated INTEGRAL/IBIS count rate was about ${\sim}$10x higher than usual for the hard state. To our knowledge, this is the first time that such strong flaring has been seen in Cyg X-1, despite the more than 21 years of…

Products of Tribonacci Numbers that are the Products of Factorials

In 2023 Alahmadi and Luca generalized their result to the equation $T_n=m_1!m_2!\cdots m_k!$ for every $k\in\mathbb{N}$, where $m_1\leq m_2\leq\ldots\leq m_k$ listing all the solutions to this equation. Here we generalize these results further and give all the solutions to $T_nT_{n+1}T_{n+2}\cdots T_{n+r}=m_1!m_2!\cdots m_k!$ and $ …
