Abstract: The Tip of the Red Giant Branch (TRGB)-based distance method in the I band is one of the most efficient and precise techniques for measuring distances to nearby galaxies (D <= 15 Mpc). The TRGB in the near infrared (NIR) is 1 to 2 magnitudes brighter relative to the I band, and has the potential to expand the range over which distance measurements to nearby galaxies are feasible. Using Hubble Space Telescope (HST) imaging of 12 fields in 8 nearby galaxies, we determine color-based corrections and zero points of the TRGB in the Wide Field Camera 3 IR (WFC3/IR) F110W and F160W filters. First, we measure TRGB distances in the I band equivalent Advanced Camera System (ACS) F814W filter from resolved stellar populations with the HST. The TRGB in the ACS F814W filter is used for our distance anchor and to place the WFC3/IR magnitudes on an absolute scale. We then determine the color dependence (a proxy for metallicity/age) and zero point of the NIR TRGB from photometry of WFC3/IR fields which overlap with the ACS fields. The new calibration is accurate to ~1% in distance, relative to the F814W TRGB. Validating the accuracy of the calibrations, we find that the distance modulus for each field using the NIR TRGB calibration agrees with the distance modulus of the same fields as determined from the F814W TRGB. This is a JWST preparatory program and the work done here will directly inform our approach to calibrating the TRGB in JWST NIRCam and NIRISS photometric filters.

Revealing H$_2$O dissociation in WASP-76~b through combined high- and low-resolution transmission spectroscopy
Numerous chemical constraints have been possible for exoplanetary atmospheres thanks to high-resolution spectroscopy (HRS) from ground-based facilities as well as low-resolution spectroscopy (LRS) from space. These two techniques have complementary strengths, and hence combined HRS and LRS analyses have the potential for more accurate abundance constraints and increased sensitivity to trace species. In this work we retrieve the atmosphere of the ultra-hot Jupiter WASP-76~b, using high-resolutio…

Small Logic-based Multipliers with Incomplete Sub-Multipliers for FPGAs
There is a recent trend in artificial intelligence (AI) inference towards lower precision data formats down to 8 bits and less. As multiplication is the most complex operation in typical inference tasks, there is a large demand for efficient small multipliers. The large DSP blocks have limitations implementing many small multipliers efficiently. Hence, this work proposes a solution for better logic-based multipliers that is especially beneficial for small multipliers. Our work is based on the m…

We consider approximating solutions to parameterized linear systems of the form $A(μ_1,μ_2) x(μ_1,μ_2) = b$, where $(μ_1, μ_2) \in \mathbb{R}^2$. Here the matrix $A(μ_1,μ_2) \in \mathbb{R}^{n \times n}$ is nonsingular, large, and sparse and depends nonlinearly on the parameters $μ_1$ and $μ_2$. Specifically, the system arises from a discretization of a partial differential equation and $x(μ_1,μ_2) \in \mathbb{R}^n$, $b \in \mathbb{R}^n$. This work combines companion linearization wi…

In recent work of Chapuy and Dolega a new variant of Hurwitz numbers with fixed genus $0$ target was introduced that includes maps between between non-orientiable surfaces. These numbers are called $b$-Hurwitz numbers and are polynomials in a parameter $b$ which measures the non-orientability of the involved ma…

Materials that transition between metal and insulator, the two opposing states that distinguish all solids, are fascinating because they underlie many mysteries in the physics of the solid state. In 1T-TaS$_{2}$, the metal-insulator transition is linked to a series of metastable states of a chiral charge density wave whose basic nature is still an open question. In this work, we show that pulses of current through these materials create current-carrying boundary channels that distinguish the me…

Reverse Training to Nurse the Reversal Curse
Large language models (LLMs) have a surprising failure: when trained on "A has a feature B", they do not generalize to "B is a feature of A", which is termed the Reversal Curse. Even when training with trillions of tokens this issue still appears due to Zipf's law - hence even if we train on the entire internet. This work proposes an alternative training scheme, called reverse training, whereby all words are used twice, doubling the amount of available tokens. The LLM is trained in both forward…

Because there is nothing better than a black-and-white widescreen film. The other widescreen B&W lists on here omitted Regalscope Westerns. Not this one, pal! Tohoscope, Regalscope, CinemaScope,  Warnerscope, TotalScope… all wide format b&w films included. A work in progress so feel free to add any missing films in comments although I'm more interested in pre-1970 and foreign language at the moment. But what to do about VistaVision? I’m as confused as you are.

The GAPS Programme at TNG LIV. Multiple molecular species in the atmosphere of HAT-P-11 b and review of the HAT-P-11 planetary system
The atmospheric characterisation of hot and warm Neptune-size exoplanets is challenging due to their small radius and atmospheric scale height. The warm-Neptune HAT-P-11b is a remarkable target for such characterisation due to the large brightness of its host star (V=9.46 mag; H=7.13 mag). This work aims at: (i) reviewing the main physical and architectural properties of the HAT-P-11 planetary system; (ii) probing the presence of 8 molecular species in the atmosphere of HAT-P-11b at high spectr…

Prosolvable rigidity of surface groups
Surface groups are known to be the Poincaré Duality groups of dimension two since the work of Eckmann, Linnell and Müller. We prove a prosolvable analogue of this result that allows us to show that surface groups are profinitely (and prosolvably) rigid among finitely generated groups that satisfy $\mathrm{cd}(G)=2$ and $b_2^{(2)}(G)=0$. We explore two other consequences. On the one hand, we derive that if $u$ is a surface word of a finitely generated free group $F$ and $v\in F$ is measure e…

Navigating the Science System: Research Integrity and Academic Survival Strategies - Science and Engineering Ethics
Research Integrity (RI) is high on the agenda of both institutions and science policy. The European Union as well as national ministries of science have launched ambitious initiatives to combat misconduct and breaches of research integrity.

Rather than framing misconduct as a result of an informat…

Probing quantum decoherence at Belle II and LHCb
With the advent of Belle II and the LHCb upgrade, the precision measurements of various B-Physics observables are on cards. This holds significant potential for delving into physics beyond the standard model of electroweak interactions. These measurements can also serve as means to establish limits on phenomena occurring at much finer length scales, such as quantum decoherence, which may arise due to potential discreteness in space-time or non-trivial topological effects. In this work, we set u…

On the fifth and subsequent positive elements in the greedy $B_h$-set
A set ${A}$ of nonnegative integers is called a $B_h$-set if every solution to \(a_1+\dots+a_h = b_1+\dots+b_h\), where $a_i,b_i \in {A}$, has $\{a_1,\dots,a_h\}=\{b_1,\dots,b_h\}$ (as multisets). Let $γ_k(h)$ be the $k$-th positive element of the greedy $B_h$-set. Previous work has given formulas for $γ_i(h)$ for $0\le i \le 4$. We give a nontrivial lower bound on $γ_5(h)$, and a nontrivial upper bound on $γ_k(h)$ for $k\ge 5$. Both the upper and lower bounds are of the form $C_k h^{k-1}+O…

Synchronicity of descent and excedance enumerators in the alternating subgroup
Generalising the work of Dey, we define the notion of ultra-synchronicity of sequences of real numbers. Let $B_{n,k},C_{n,k},P_{n,k},Q_{n,k}$ be the number of even permutations with $k$ descents, odd permutations with $k$ descents, even permutations with $k$ excedances and odd permutations with $k$ excedances respectively. We show that the four sequences are ultra-synchronised for all $n\ge 5$. This proves a strengthening of two conjectures of Dey.

Statistical relations between spectropolarimetric observables and the polar strength of the stellar dipolar magnetic field

Statistical relations between spectropolarimetric observables and the polar strength of the stellar dipolar magnetic field
Global magnetic fields of early-type stars are commonly characterised by the mean longitudinal magnetic field $\langle B_{\rm z} \rangle$ and the mean field modulus $\langle B \rangle$, derived from the circular polarisation and intensity spectra, respectively. Observational studies often report a root mean square (rms) of $\langle B_{\rm z} \rangle$ and an average value of $\langle B \rangle$. In this work, I used numerical simulations to establish statistical relationships between these cumul…

Hunting for $X_b$ via hidden bottomonium decays $X_b\to ππχ_{bJ}$
In this work, we investigate the isospin breaking decay $X_b \to π^0χ_{bJ}$ and the isospin conserved decay $X_b \to ππχ_{bJ}$, where $X_b$ is taken to be the heavy quark flavor symmetry counterpart of $X(3872)$ in the bottomonium sector as a $B^*\bar B$ molecule candidate. Since the mass of this state may be far below the $B {\bar B}^*$ threshold and the mass difference between the neutral and charged bottom meson is small compared to the binding energy of the $X_b$, the isospin-violating…

On the Optimality of CVOD-based Column Selection
While there exists a rich array of matrix column subset selection problem (CSSP) algorithms for use with interpolative and CUR-type decompositions, their use can often become prohibitive as the size of the input matrix increases. In an effort to address these issues, the authors in \cite{emelianenko2024adaptive} developed a general framework that pairs a column-partitioning routine with a column-selection algorithm. Two of the four algorithms presented in that work paired the Centroidal Voronoi…

In this work, we study type B set partitions for a given specific positive integer $k$ defined over $\langle n\rangle=\{-n, -(n-1),\cdots -1,0,1,\cdots n-1,n\}$. We found a few generating functions of type B analogue for some of the set partition statistics defined by Wachs, White and Steingrimsson for partitions over positive integers $[n] =\{1,2,\cdots n\}$, both for standard and ordered set partitions respectively. We extended the idea of restricted growth functions utilized by Wachs and Whi…

Production of $P^Λ_{ψs}(4338)$ from $Ξ_b$ decay
In the present work, we investigate the production of the newly observed $P^Λ_{ψs}(4338)$ state in $Ξ_b^-$ decay, where the $P^Λ_{ψs}(4338)$ is assigned as $Ξ_c \bar{D}$ molecular state. By using an effective Lagrangian approach, we evaluate the branching fractions of $Ξ_b^-\rightarrow P^Λ_{ψs}(4338)K^-$ via the triangle loop mechanism. The branching fractions of $Ξ_b^-\rightarrow P^Λ_{ψs}(4338)K^-$ is in the order of $10^{-4}$, the result are compared with our previous work of $Ξ_…

The Width of an Electron-Capture Neutrino Wave Packet

https://arxiv.org/abs/2404.19746 https://arxiv.org/pdf/2404.19746
arXiv:2404.19746v1 Announce Type: new
Abstract: We expand on the methodology outlined in previous work that predicted the width of an antineutrino wave packet emerging from a beta-decaying nucleus, to the case of a neutrino from electron capture decay. Based on this result, we also respond to a recent Beryllium Electron capture in Superconducting Tunnel junctions Experiment (BeEST) paper which utilizes this previous work in forming their measurement of the neutrino wave packet width. According to our interpretation, the direct limit on the neutrino wave packet width from electron capture decay ($e^- \mathrm{^{7}Be}\rightarrow\mathrm{^{7}Li \nu_e}$) using the BeEST analysis should map to $\sigma_{\nu,x}>6.2\,\mathrm{pm}$ while our theoretical prediction is $\sigma_{\nu,x}\sim2.7\,\mathrm{nm}$.

I like how NYS has set up a state organization that is so convoluted (OPWDD) that it _requires_ a third-party care organization simply to navigate the bureaucracy and apply to determine eligibility. That's not a nice-to-have, it's a requirement. All forms and eligibility documentation needs to be submitted through the third-party non-profit. Truly excellent work, NY.

The quark flavor-violating ALPs in light of B mesons and hadron colliders
The axion-like particle (ALP) may induce flavor-changing neutral currents (FCNCs) when their Peccei-Quinn charges are not generation universal. The search for flavor-violating ALP couplings with a bottom quark so far focused on FCNC processes of $B$ mesons at low energies. The recent measurements of $B\to K +X$ rare decays place stringent bounds on the quark flavor violations of a light ALP in different decay modes. In this work we propose a novel direct search for bottom flavor-violating inter…

The $B^0 \to J/ψf_0(1370,1500,1710)$ decays: an opportunity for scalar glueball hunting
The scalars $f_0$ closest to 1.5 GeV contain the mesons $f_0(1370)$, $f_0(1500)$ and $f_0(1710)$, and the latter two ones are usually viewed as the potential candidates for the scalar glueballs. In this work, by including the important contributions from the vertex corrections, we study the decays $B^0 \to J/ψf_0$ within the improved perturbative QCD approach and analyze the possible scalar glueball hunting. Together with the two mixing models, namely, $f_0(1500) (f_0(1710))$ being the primary…
