Objective: The aim of this study was to evaluate the relationship between single nucleotide polymorphism (SNP) (-135 T>C) of TNFRSF1 A and the frequency of occurrence and severity of oral mucositis (OM) in patients with head and neck cancer (HNC) treated with radiotherapy (RT).
Study Design: This retrospective, cohort study included 60 patients with HNC treated with intensity-modulated radiation therapy (IMRT). TNFRSF1 A SNP analysis (-135 T>C) was performed by using molecular probes (TaqMan, ThermoFisher Scientific, Waltham, MA) in DNA isolated from peripheral blood (QIAamp DNA MiniKit; Qiagen, Germantown, MD).
Results: CC genotype was related to 4.5-fold higher risk of grade 2 OM after the second week of RT. Similarly, CC carriers had a significantly higher risk of severe (grade 3) OM after the fourth (6-fold) and fifth (7.5-fold) weeks of RT. The CC genotype of the TNFRSF1 A gene was significantly correlated with a higher risk of shorter overall survival (OS) (> 37 months follow-up period; hazard ratio [HR] = 2.78).
Conclusions: SNP (-135 T>C) of the TNFRSF1 A gene may act as a predictor of OM occurrence in patients with HNC treated with IMRT. The studied SNP may also serve as a prognostic factor in such cases.

We study the diffusion of a particle with a time-dependent diffusion coefficient D(t) that switches between random values drawn from a distribution W(D) at a fixed rate r. Using a renewal approach, we compute exactly the moments of the position of the particle ⟨x^{2n}(t)⟩ at any finite time t, and for any W(D) with finite moments ⟨D^{n}⟩. For t≫1, we demonstrate that the cumulants ⟨x^{2n}(t)⟩_{c} grow linearly with t and are proportional to the free cumulants of a random variable distributed according to W(D).

We report the first observation of a momentum-resolved superconducting gap in the Hg-based trilayer cuprate, which holds the highest record of superconducting transition temperature (T_{c}) at ambient pressure. By angle-resolved photoemission spectroscopy utilizing a microfocused beam, clear quasiparticle dispersions originating from the inner and outer CuO_{2} planes (IP and OP, respectively) were separately identified. The magnitude of the superconducting gap for the IP was comparable to that of the Bi-based trilayer cuprate with a lower T_{c}.

Covalent organic frameworks (COFs) are promising photocatalysts for HO photosynthesis, but charge carrier separation remains a critical challenge. Donor-acceptor COFs enhance charge separation, but the slow kinetics of water oxidation and oxygen reduction reactions lead to carrier accumulation, thereby decreasing efficiency. Here, we report T-C type COFs (T = trap units, C = catalytic units), demonstrating that units with keto-enol tautomerism can serve as dynamic electron/hole traps (T) to mitigate Coulomb forces.

We investigate resistive anomalies in metals near a ferromagnetic phase transition, emphasizing the role of long-range critical fluctuations. Our analysis shows that electron diffusion near the critical temperature T_{c} enhances the singular behavior of resistivity via a classical memory effect, exceeding the prediction of Fisher and Langer [Phys. Rev.

We study the ensemble of states generated by performing projective measurements on the output of a random matchgate (or free-fermionic) quantum circuit. We rigorously show that this "projected ensemble" exhibits deep thermalization: for large system sizes, it converges toward a universal ensemble that is uniform over the manifold of Gaussian fermionic states. As well as proving momentwise convergence of these ensembles, we demonstrate that the full distribution of any physical observable in the projected ensemble is close to its universal form in Wasserstein-1 distance, which we argue is an appropriate and efficiently computable measure of convergence when studying deep thermalization.
