Proton Charge Radius and Precision Tests of QED
, 2014 The "proton radius puzzle" remains unsolved since it was established in 2010. This paper summarizes the current state and gives an overview over upcoming experiments.

CA: A Cancer Journal for Clinicians, Volume 76, Issue 1, January/February 2026.Abstract The therapeutic landscape for renal cell carcinoma (RCC) and urinary tract cancer (UTC) has transformed dramatically, creating complexity in treatment selection and sequencing. The 2025 Advanced Urologic Cancer Consensus Conference was convened to establish evidence‐based expert consensus recommendations for optimal management.

Equilibrium Existence in First‐Price Auctions With Private Values
Econometrica, Volume 94, Issue 1, Page 193-224, January 2026.We provide sufficient conditions for equilibrium existence in first‐price auctions with private values that accommodate non quasi‐linear utilities and value‐distributions that contain atoms and exhibit positive or negative correlation. These conditions show that equilibrium existence often turns on properties of a single statistic of the joint ...

Efficiency of different matrix inversion methods applied to Wilson fermions
, 1996 We compare different conjugate gradient -- like matrix inversion methods (CG, BiCGstab1 and BiCGstab2) employing for this purpose the compact lattice quantum electrodynamics (QED) with Wilson fermions.

Multidimensional Screening With Precise Seller Information
Econometrica, Volume 94, Issue 1, Page 35-70, January 2026.A multi‐product monopolist faces a buyer who is privately informed about his valuations for the goods. As is well known, optimal mechanisms are in general complicated, while simple mechanisms—such as pure bundling or separate sales—can be far from optimal and do not admit clear‐cut comparisons.

Sympathetic cooling of $^4$He$^+$ ions in a radiofrequency trap
, 2004 We have generated Coulomb crystals of ultracold $^4$He$^+$ ions in a linear radiofrequency trap, by sympathetic cooling via laser--cooled $^9$Be$^+$. Stable crystals containing up to 150 localized He$^+$ ions at $\sim$20 mK were obtained.

School‐Based Interventions for Reducing Disciplinary School Exclusion. An Updated Systematic Review
Campbell Systematic Reviews, Volume 21, Issue 4, December 2025.ABSTRACT School exclusion—commonly referred to as suspension—is a disciplinary response employed by school authorities to address student misbehaviour. Typically, it involves temporary removal from regular teaching or, in more serious cases, complete removal from the school premises.

Improved Theory of the Muonium Hyperfine Structure
, 1994 Terms contributing to the hyperfine structure of the muonium ground state at the level of few tenths of kHz have been evaluated. The $\alpha^2 (Z\alpha)$ radiative correction has been calculated numerically to the precision of 0.02 kHz.

Campbell Systematic Reviews, Volume 21, Issue 4, December 2025.ABSTRACT Background: Climate change and widespread environmental degradation have increased the risk of natural hazards in recent decades. Hydrological, meteorological, and climatological disasters have become more frequent globally (Parry et al. 2007; Cavallo and Noy 2009; CRED 2022), affecting over 3.9 billion people since 2000 and causing losses ...
