Gradient properties of $\varphi^3$ in $d=6-\varepsilon$

Gradient properties of $φ^3$ in $d=6-\varepsilon$
The renormalization group flow of the multiscalar interacting $φ^3$ theory in $d=6$ dimensions is known to have a gradient structure, in which suitable generalizations of the beta functions $B^{I}$ emerge as the gradient of a scalar function $A$, $\partial_I A = T_{IJ} B^J $, with a nontrivial tensor $T_{IJ}$ in the space of couplings. This has been shown directly to three loops in schemes such as $\overline{\rm MS}$ and can be argued in general by identifying $A$ with the coefficient of the t…

Quantitative Macromolecular Proton Fraction Imaging using Pulsed Spin-Lock
Purpose: Recent studies have shown that spin-lock MRI can simplify quantitative magnetization transfer (MT) by eliminating its dependency on water pool parameters, removing the need for a T1 map in macromolecular proton fraction (MPF) quantification. However, its application is often limited by the requirement for long radiofrequency (RF) pulse durations, which are constrained by RF hardware capabilities despite remaining within specific absorption rate (SAR) safety limits. Methods: To addres…

Infection dynamics for fluctuating infection or removal rates regarding the number of infected and susceptible individuals
In general, the rates of infection and removal (whether through recovery or death) are nonlinear functions of the number of infected and susceptible individuals. One of the simplest models for the spread of infectious diseases is the SIR model, which categorizes individuals as susceptible, infectious, recovered or deceased. In this model, the infection rate, governing the transition from susceptible to infected individuals, is given by a linear function of both susceptible and infected populati…

The work is motivated by the concerns in magnetic resonance imaging safety and their practical evaluation in clinical environments. Whereas demagnetizing tensor is a well-defined concept in the principal axes, its transformation under three-dimensional reorientation is often overlooked - a justifiable omission for solutions derived from Poisson equation, whe…

Design and performance of a Toroidal RF Volume Coil with Intrinsic Electromagnetic Interference Rejection for low-field Portable Halbach-Based MRI Systems
Purpose: One of the intrinsic limitations of low-field MRI is low signal-to-noise ratio (SNR), which can be further reduced by electromagnetic interference (EMI) due to the lack of a Faraday shielded room. To address this issue, we propose a novel RF coil design that is inherently less sensitive to EMI while maintaining high receive sensitivity. Methods: The proposed coil structure is based on an anapole (toroidal) design and consists of six rings, each containing four continuous wires wound ar…

Our modeling results show that the interval between vaccine doses is a key control parameter that can be tuned to significantly influence …

In our original paper (Delavaux et al. 2024; https://www.nature.com/articles/s41586-024-07110-y), we find that the latitudinal diversity gradient (LDG) in plant species richness is reduced on oceanic islands worldwide. Moreover, we find that plants that associate with mutualists, including pollinators, AM fungi, and N-fixing bacteria, disproportionately contribute to this reduction. To make this assertion, we fit models of continental diversity to absolute latitude and compared mainland diversi…

Decoding Breast Cancer in X-ray Mammograms: A Multi-Parameter Approach Using Fractals, Multifractals, and Structural Disorder Analysis
We explored the fractal and multifractal characteristics of breast mammogram micrographs to identify quantitative biomarkers associated with breast cancer progression. In addition to conventional fractal and multifractal analyses, we employed a recently developed fractal-functional distribution method, which transforms fractal measures into Gaussian distributions for more robust statistical interpretation. Given the sparsity of mammogram intensity data, we also analyzed how variations in intens…

Computing phylogenetic invariants for time-reversible models: from TN93 to its submodels
Phylogenetic invariants are equations that vanish on algebraic varieties associated with Markov processes that model molecular substitutions on phylogenetic trees. For practical applications, it is essential to understand these equations across a wide range of substitution models. Recent work has shown that, for equivariant models, phylogenetic invariants can be derived from those of the general Markov model by restricting to the linear space defined by the model (namely, the space of mixtures …

Mathematical models for therapeutic approaches involving electric conductors or shielding
We set up a mathematical model for a DC current in a human tissue that shows an attenuation effect in an extended circuit. We give a positive lower bound on the time duration over which this is guaranteed to happen in terms of the parameters of the model. We also discuss shielding and coupling in the context of electrical aspects of biological processes.

Is GGAG:Ce@SiO$_2$-RB composite a prospective material for X-ray induced photodynamic therapy?
Nanocomposite material ($\mathrm{GGAG:Ce^{3+}@SiO_2-RB}$) for potential use in X-ray induced photodynamic therapy (X-PDT) was developed, thoroughly characterized, and evaluated. It consists of a scintillating $\mathrm{Gd_3(Ga_{1-x}Al_x)_5O_{12}:Ce^{3+}}$ core encapsulated in silica layer and functionalized with the photosensitizer Rose Bengal (RB). Radioluminescence measurements confirmed the energy transfer from the scintillating core to Rose Bengal. Dark toxicity and radiosensitisation effect…

Characterizing (multi-)semi-directed phylogenetic networks
In evolutionary biology, phylogenetic networks are graphs that provide a flexible framework for representing complex evolutionary histories that involve reticulate evolutionary events. Recently phylogenetic studies have started to focus on a special class of such networks called semi-directed networks. These graphs are defined as mixed graphs that can be obtained by de-orienting some of the arcs in some rooted phylogenetic network, that is, a directed acyclic graph whose leaves correspond to a …

Adding a fecundity-survival trade-off to a discrete population model with maturation delay
Although maturation delays of new individuals are frequently added in population models, researchers rarely account for the mortality of individuals between birth and maturity. Previous studies have added mortality of immature individuals to the maturation delay in discrete population models, finding that increasing the delay results in a decreased population level at equilibrium. Furthermore, increasing the maturation delay beyond a critical threshold ultimately leads to the extinction of the …

Pre-exposure prophylaxis and syphilis in men who have sex with men: a network analysis
Pre-exposure prophylaxis (PrEP) has been established as an effective tool for preventing HIV infection among men who have sex with men (MSM). However, there is the possibility of PrEP usage leading to increased sexual partners and increased transmission of non-HIV sexually transmitted infections such as syphilis. We take here a network perspective to examine this possibility using data on sexual partnerships, demographic data, PrEP usage, and syphilis among MSM in Columbus, Ohio. We use a recen…

Posterior bounds on divergence time of two sequences under dependent-site evolutionary models
Let x and y be two length n DNA sequences, and suppose we would like to estimate the divergence time T. A well known simple but crude estimate of T is p := d(x,y)/n, the fraction of mutated sites (the p-distance). We establish a posterior concentration bound on T, showing that the posterior distribution of T concentrates within a logarithmic factor of p when d(x,y)log(n)/n = o(1). Our bounds hold under a large class of evolutionary models, including many standard models that incorporate site de…
