Explaining the mechanisms behind model predictions is a common strategy in AI-assisted decision-making to help users rely appropriately on AI. However, recent research shows that the effectiveness of explanations depends on numerous factors, leading to mixed results, with many studies finding no effect or even an increase in overreliance, while exp...
In this paper, we deal with non-degenerate translators of the mean curvature flow
in the well-known Einstein’s static universe. We focus on the rotationally invariant
translators, that is, those invariant by a natural isometric action of the special
orthogonal group on the ambient space. In the classification list, there are three
space-like cases...
Obesity is a critical public health issue, necessitating effective weight loss interventions. While various dietary regimens have been explored, individual responses to interventions often vary. This study involved a 3-month dietary intervention aiming at assessing the role of macronutrient composition and the potential role of genetic predispositi...
Backtracking line search is foundational in numerical optimization. The basic idea is to adjust the step size of an algorithm by a constant factor until some chosen criterion (e.g. Armijo, Goldstein, Descent Lemma) is satisfied. We propose a new way for adjusting step sizes, replacing the constant factor used in regular backtracking with one that t...
In this work, variations in the channel length and gate oxide thickness are studied for the design optimization of 3300 V 4H-SiC based VDMOSFETs. For this, a batch of 3 wafers was processed and tested for key device characteristics. The results indicate shorter channel length of 0.5 μm leads to an increase in the drain leakage current, thus affecti...
This paper addresses the longstanding problem of the existence of odd perfect numbers by leveraging a newly defined function a m (n). The function a m (n) encapsulates the behavior of divisor sums in the complex plane and is used to analyze whether a number n can be perfect. By applying the Möbius inversion formula and systematically evaluating the...
This paper aims to clarify the effect of organizational communication on achieving the effectiveness of administrative decisions in organizations. Data was collected from previous studies using the descriptive analysis method. The findings confirm that the effect of organizational communication leads to the achievement of the effectiveness of manag...
Proposed financial risk checks are more usefully evaluated by directly estimating the impact of £150 monthly thresholds on different risk groups. Re-analysis shows the typical 'unharmed' [Problem Gambling Severity Index (PGSI) = 0] gambler in our data is flagged 0.28 times per annum by these, whereas the average 'at-risk' gambler (PGSI > 0) is flag...
In 2015 Hikami and Inoue constructed a representation of the braid group in terms of cluster algebra associated with the decomposition of the complement of the corresponding knot into ideal hyperbolic tetrahedra. This representation leads to the calculation of the hyperbolic volume of the complement of the knot that is the closure of the correspond...
Xylem air embolism is the primary cause of drought‐related tree mortality. Phenotypic plasticity of xylem traits is key for species acclimation to environmental variability and evolution. It is widely believed that plants increase xylem embolism resistance in response to drought. However, I argue that this hypothesis, based on extensive literature,...
This article provides a proof that the Ramanujan's Inequality given by, $$\pi(x)^2 < \frac{e x}{\log x} \pi\Big(\frac{x}{e}\Big)$$ holds unconditionally for every $x\geq \exp(43.5102146)$. In case for an alternate proof of the result stated above, we shall exploit certain estimates involving the Chebyshev Theta Function, $\vartheta(x)$ in order to...
Triangulation is widely used to represent models of real objects in digital form, and often, in order to get the desired model, we need to triangulate it from data of another kind, for example, from a voxel model. There are methods that allow one to do it, but the resulting triangulation does not always have the desired quality. One way to solve th...
Fourier-Motzkin elimination, a standard method for solving systems of linear inequalities, leads to an elementary, short, and self-contained proof of von Neumann's minimax theorem.
Motivated by conjectures about near-horizon dynamics in quantum gravity, we search for lines of perturbatively accessible fixed points emanating from models of N free fermions. Through two loops we find a new class of models, apart from the well-known Abelian Thirring models. Further study is needed to see whether these can lead to true conformal m...
Garavisha is a type of artificial poisoning, which is slowly metabolised or digested in the body and leads to hepatotoxicity. Abhayadi ghrita, mentioned in Bhasavarajeeyam in Vishaprakarana, can cure all types of poisoning. All the drugs in this Ghrita show hepatoprotective activity. This article explains the hepatoprotective activity of Abhayadi g...
Let $e$ be an integer at least two. We define the $e$-core and the $e$-weight of a multipartition associated with a multicharge as the $e$-core and the $e$-weight of its image under the Uglov map. We show how these definitions lead to the definition of the $e$-core and the $e$-weight of a block of an Ariki-Koike algebra with quantum parameter $e$,...
We derive methods for risk-neutral pricing of multi-asset options, when log-returns jointly follow a multivariate tempered stable distribution. These lead to processes that are more realistic than the better known Brownian motion and stable processes. Further, we introduce the diagonal tempered stable model, which is parsimonious but allows for ric...
Patients with compromised respiratory function frequently require mechanical ventilation to survive. Unfortunately, non-uniform ventilation of injured lungs generates complex mechanical forces that lead to ventilator induced lung injury (VILI). Although investigators have developed lung-on-a-chip systems to simulate normal respiration, modeling the...
The category $STROP_m$ of supertropical monoids, whose morphisms are transmissions, has the full--reflective subcategory $STROP$ of commutative semirings. In this setup, quotients are determined directly by equivalence relations, as ideals are not applicable for monoids, leading to a new approach to factorization theory. To this end, tangible facto...
Take home message The diagnosis and treatment of obstructive sleep apnea (OSA) in patients with resistant hypertension leads to a beneficial long-term decrease in blood pressure. However, over time, this improvement is only partially sustained in severe-OSA patients. ABSTRACT There is a close relationship between obstructive sleep apnea (OSA) and r...
Several methods are used to evaluate finite trigonometric sums. In most cases, either the sum had not previously been evaluated, or it had been evaluated, but only by analytic means, e.g., by complex analysis or modular transformation formulas. We establish both reciprocity and three sum relations for trigonometric sums. Motivated by certain sums t...
Characterizing the $6\times 6$ complex Hadamard matrices (CHMs) is an open problem in linear algebra and quantum information. In this paper, we investigate the eigenvalues and eigenvectors of CHMs. We show that any $n\times n$ CHM with dephased form has two constant eigenvalues $\pm\sqrt{n}$ and has two constant eigenvectors. We obtain the maximum...
We show that the recent breakthrough result of Buchbinder and Feldman [1] could further lead to a deterministic $(1 − \kappa_{f}/e − \varepsilon)$-approximate algorithm for maximizing submodular function $f$ with curvature $\kappa_{f}$ under matroid constraint.
This poster shows results from various shape recognition experiments. We investigated the impact of rotation, occlusion, and the difference between points of maximum convex curvature and points of maximum information in a shape-matching task. In line with previous results from our lab (Schmidtmann et al., 2015), these results again demonstrate the...
Three-dimensional Dirac semimetals (DSMs) have been shown to exhibit one-dimensional hinge modes which are termed the higher-order hinge Fermi-arc (HOFA) states. They are the topological consequences of Dirac points. Superconducting states from Dirac semimetals can inherit the Dirac points to form nodal Dirac superconducting states, raising a quest...

We have investigated bound state solutions for a scalar particle described in the spacetime of a chiral cosmic string subjected to rotational effects in a Kaluza-Klein theory. We saw that combinations between the parameters that describe the generalized spacetime impose upper and lower limits for the radial coordinate leading to well-established bo...
1. August: a turning point, i.e. a new high, with a possibility to go down. While it may rise, there could be a misleading decline soon after.
2. Support: 2370 down to 2300. A drop below 2300 will trigger panic, causing further decline.
3. September: highly chaotic, marked by panic, high volatility, and sharp declines or sudden movements up and dow...
An explicit quantization of Chern-Simons theory leads to an identity between sums of the Kac-Weyl characters. One can use this identity to prove inequalities that constrain the fusion coefficients $N_{\mu\nu}^l$ in the case of RCFTs that descend from current algebras. It also leads to a statement regarding the conjugacy symmetry of the sums of squa...
The Eucharistic Liturgy in the Syro Malabar (East Syriac) tradition leads one to integration of human being and this cosmos into Christ and their deification. Baptism and the Sacrament of Perfection (Chrismation) the sacramental beginning of this process. The Eucharistic Liturgy (Holy Qurbana) further intensifies this process of integration and dei...
Convenient and consistent phase convention is important in the construction of the hadronic Lagrangian. However, the importance of phase convention has been overlooked for a long time, and the sources of different conventions are never explicitly addressed. This obscure situation can cause mistakes and misinterpretations in hadron physics. In this...
Diseases affecting the nervous system are diverse. A recent global burden of disease study found that nervous system diseases were the leading cause of disability-adjusted life-years (DALYs) in 2021 [...]
Savage’s famous representation theorem is based on seven postulates of rational choice. We resolve some loose ends in the literature concerning the relationship between different versions of Savage’s axioms. This leads us to the present form of the representation theorem. We also discuss some issues regarding the historical development of Savage’s...
We present a representation of skew-orthogonal polynomials of symplectic type ($\beta=4$) in terms of a matrix Riemann-Hilbert problem, for weights of the form ${\rm e}^{-V(z)}$ where $V$ is a polynomial of even degree and positive leading coefficient. This is done by representing skew-orthogonality as a kind of multiple-orthogonality. From this, w...
This paper characterises the subspaces of $H^2(\mathbb D)$ simultaneously invariant under $S^2 $ and $S^{2k+1}$, where $S$ is the unilateral shift, then further identifies the subspaces that are nearly invariant under both $(S^2)^*$ and $(S^{2k+1})^*$ for $k\geq 1$. More generally, the simultaneously (nearly) invariant subspaces with respect to $(S...

Henry Mintzberg is one of the pioneering management scholars who has extensively researched the strategising processes of firms. Therefore, Mintzberg can be regarded as a seminal figure from the perspective of Strategy as Practice (SAP). Interestingly, the debate on the influence of eminent strategy process thinkers such as Mintzberg, Andrew Pettig...
It becomes possible to calculate the exact number of neutrons of the black hole in Cygnus X-1.
The identity of the Eastern Atlantic Terebridae species Hastula exacuminata Sacco, 1891, Hastula aciculina (Lamarck, 1822) and Hastula lepida (Hinds, 1844) are re-evaluated based on a recent study of specimens in various collections. Protoconchs-extremely rarely in pristine condition-for all these species were only recently available in representab...
We propose a new renormalization scheme in the two Higgs doublet models with a softly-broken $Z_2$ symmetry and CP-conservation in the Higgs sector. In this scheme, counterterms for mixing angles of the Higgs bosons are determined by using the decay rates of the discovered Higgs boson $h$, $i.e.$, $h \to \tau^+\tau^-$ and $h \to ZZ^* \to Z\ell^+\el...
Managers’ reliance on established mental models for decision-making, without adapting them to the relevant context, presents risks when integrating into a foreign market. As the mental models may be calibrated to other, more familiar, contexts, they can lead to misunderstandings and errors when applied in unfamiliar international settings. We intro...
A (generalized) topological space is called an iso-dense space if the set of all its isolated points is dense in the space. The main aim of the article is to show in $$\textbf{ZF}$$ ZF a new characterization of iso-dense spaces in terms of special quasiorders. For a non-empty family $$\mathcal {A}$$ A of subsets of a set X , a quasiorder $${{\,\mat...
For a negative definite plumbed three-manifold, we give an integral representation of the appropriate average of the GPPV invariants of Gukov--Pei--Putrov--Vafa, which implies that this average admits a resurgent asymptotic expansion, the leading term of which is the Costantino--Geer--Patureau-Mirand invariant of the three-manifold. This proves a c...

Using a lab-in-the-field experiment with Ugandan fishers, we study if and how the use of a common pool resource changes when the resource is either scarce or abundant and when the number of users increases over time. Both resource scarcity and a growing group require users to be more constrained, that is, more cooperative, in order to maintain the...
Two cosmological parameters from the Planck results of 2018 allowed us to perform H0 ≈ (72.0 ± 0.1) km s −1 Mpc −1.
Reducing the lag in the accuracy assessment of multi-temporal land-cover products has been a hot research topic. By identifying the changed strata, the annual accuracy in multi-temporal products can be quickly evaluated. However, there are still two limitations in the accuracy assessment of multi-temporal products. Firstly, the setting of the param...

If $A=(A,\oplus,\odot)$ is a $\lambda$-homomorphic brace with $(A,\oplus)=\mathbb{Z}^2$, then the operations in this brace are given by formulas \begin{align*}\begin{pmatrix}a_1\\a_2\end{pmatrix}\oplus\begin{pmatrix}b_1\\b_2\end{pmatrix}=\begin{pmatrix}a_1+b_1\\a_2+b_2\end{pmatrix},&&\begin{pmatrix}a_1\\a_2\end{pmatrix}\odot\begin{pmatrix}b_1\\b_2\...
Light bosonic dark matter fields that can be treated like a classical wave have non-linear field values close to massive bodies. Here we make the important observation that the quadratic interactions of axion dark matter lead to a divergence of the axion field value resulting in a non-physical parameter space for values of the decay constant of $f\...

An article for the lay person regarding birth canal injuries leading to fistula formation
Ratios m s / m d and m u / m d of the light quark masses have been determined from expressions for squared masses of pseudoscalar mesons $$m_{\pi }^{2}$$ and $$m_{K}^{2}$$ obtained with an accuracy of the second order in chiral symmetry breaking. The fit of the theoretical expressions for $$m_{\pi }^{2}$$ and $$m_{K}^{2}$$ to their phenomenological...
We consider spaces introduced by N. K. Karapetyants and B. S. Rubin in 1982, to characterize, in particular, the image of the fractional integral Riemann–Liouville operator. These spaces lie near $${L}^{\infty }$$ L ∞ . We show that they coincide with well-known Lorentz–Zygmund spaces. This allows us to reformulate one result from N. K. Karapetyant...
The present work explores and demonstrates the electrochemical sensing capability of a highly stable bimetallic gold–copper nanocluster. The nanocluster can selectively sense heavy metal ion lead, Pb(II), through a specific gold–Pb(II) interaction and is successfully extended to real sample analysis as well. Thus, a real-time monitoring strategy ha...

Multiple methods are used to tackle ipsilateral obstructed venous access in patients undergoing a device upgrade by implanting a new left ventricular lead. One feasible solution to tackle this is implantation of the upgrade lead contralaterally with pre‐sternal tunnelization to the opposite side under conscious sedation.
Metallic structures, introduced by V. de Spinadel in 2002, opened a new avenue in differential geometry. Building upon this concept, C. E. Hreţcanu and M. Crasmareanu laid the foundation for metallic Riemannian manifolds in 2013. The field's rich potential and diverse applications have since attracted significant research efforts, leading to a weal...
Let $\mu$ be a positive measure supported on a domain $\Omega$. We consider the behavior of the balayage measure $\nu:=\mathrm{Bal}(\mu,\partial \Omega)$ near a point $z_{0}\in \partial \Omega$ at which $\Omega$ has an outward-pointing cusp. Assuming that the order and coefficient of tangency of the cusp are $d>0$ and $a>0$, respectively, and that...
Nearly all empirical studies that estimate the coefficients of a risk equalization formula present the value of the statistical measure R². The R²-value is often (implicitly) interpreted as a measure of the extent to which the risk equalization payments remove the regulation-induced predictable profits and losses on the insured, with a higher R²-va...
