Lozares, S., Tur, P., Ballester, F., Bundschuh, R. A., Gonzalez-Perez, V., Jaberi, R., et al. (2025). Head and neck and skin (HNS) GEC-ESTRO and BRAPHYQS working groups joint critical review of the use of Rhenium-188 in dermato-oncology. Clin. Transl. Radiat. Oncol., 53, 100991–9pp.
Abstract: Non-melanoma skin cancers are increasing globally, prompting the need for innovative, non-invasive treatment approaches. Radioactive rhenium (188Re) paste has emerged as an open-source radiation-based modality in dermato-oncology, offering a novel alternative to conventional radiotherapy and brachytherapy. In this review, a systematic literature search was conducted using PubMed, Scopus, Web of Science, and Google Scholar for studies published over the past 20 years. Data were extracted from case series, pilot studies, and clinical trials, with particular emphasis on response rates, dosimetric parameters, and treatment-associated toxicity. Findings from approximately 240 patients demonstrated complete response rates ranging from 86 % to 100 % after one or two treatment applications, while dosimetric analyses revealed a rapid dose fall-off that effectively confines the therapeutic effect to a tissue depth of 2-3 mm, with most adverse effects being mild and transient. Notably, 188Re differs from conventional brachytherapy (specifically high-dose-rate modality) due to its open-source application and unique dosimetric profile. The use of 188Re in clinical practice mandates a highly specialized, multidisciplinary team, including radiation oncologists, nuclear medicine specialists, and experienced medical physicists, and strict quality assurance protocols, thereby limiting its application to carefully selected cases. Although 188Re therapy offers a promising alternative for the treatment of superficial skin cancers, its distinct clinical and dosimetric characteristics warrant further randomized studies with extended follow-up to validate its efficacy and refine patient selection criteria under rigorous multidisciplinary oversight.

Lorenzo-Saez, E., Urchueguia, J. F., Garcia Folgado, M., & Oliver-Villanueva, J. V. (2025). Methodology development for high-resolution monitoring of emissions in urban road traffic systems. Atmos. Pollut. Res., 16(9), 102600–12pp.
Abstract: Transport sector is a major contributor to greenhouse gas (GHG) emissions and air pollution, especially in cities. Mitigating these emissions is crucial for both climate change and public health, but current emission quantification methodologies lack sufficient resolution at the urban level to apply efficient measures. This gap is addressed by developing a novel temporal and spatial high-resolution methodology to monitor traffic-related emissions based on real-time traffic data gathered from induction loops installed in road networks. The methodology integrates vehicle fleet characteristics, emission factors, and traffic intensity to quantify street-level emissions per hour. This bottom-up approach allows for detailed monitoring of pollutants across specific locations and times. Applied to Valencia, Spain, the methodology enabled the identification of emission hotspots and the detailed assessment of local mitigation strategies. As a case study, the impact of a newly implemented bike lane was analyzed, demonstrating the method's effectiveness in evaluating sustainable mobility measures and their influence on traffic emissions. This tool provides city planners and policymakers with a robust, data-driven framework to reduce urban emissions and enhance air quality.

Abdallah, J. et al, Cerda Alberich, L., Fiorini, L., Gomez Delegido, A. J., & Valero, A. (2025). Study of the radiation hardness of the ATLAS Tile Calorimeter optical instrumentation with Run 2 data. J. Instrum., 20(6), P06006–29pp.
Abstract: This paper presents a study of the radiation hardness of the hadronic Tile Calorimeter of the ATLAS experiment in the LHC Run 2. Both the plastic scintillators constituting the detector active media and the wavelength-shifting optical fibres collecting the scintillation light into the photodetector readout are elements susceptible to radiation damage. The dedicated calibration and monitoring systems of the detector (caesium radioactive sources, laser and minimum bias integrator) allow to assess the response of these optical components. Data collected with these systems between 2015 and 2018 are analysed to measure the degradation of the optical instrumentation across Run 2. Moreover, a simulation of the total ionising dose in the calorimeter is employed to study and model the degradation profile as a function of the exposure conditions, both integrated dose and dose rate. The measurement of the relative light output loss in Run 2 is presented and extrapolations to future scenarios are drawn based on current data. The impact of radiation damage on the cell response uniformity is also analysed.

Abstract: The combined use of the inverse kinematics technique and the advanced detection setup R3B (Reactions with Relativistic Radioactive Beams) at GSI/FAIR provides unique opportunities to study the fission process. This approach provides access to the complete isotopic identification of the two fission fragments, the precise determination of their velocities and the measurement of the neutrons and gammas emitted in coincidence, for a wide range of unstable fissile nuclei. In addition, quasi-free NN scattering represents a surrogate reaction to induce fission, allowing the complete identification of the fissioning system in terms of isotopic composition and excitation energy. The manuscript describes the technical realisation of these experiments as well as the physics programme and some preliminary results.

Lopez Castro, G., Miranda, A., & Roig, P. (2025). Isospin breaking corrections in 2π production in tau decays and e plus e – annihilation: Consequences for the muon g -2 and conserved vector current tests. Phys. Rev. D, 111(7), 073004–26pp.
Abstract: We revisit the isospin-breaking corrections relating the e+e- hadronic cross section and the tau decay spectral function, focusing on the dipion channel, that gives the dominant contribution to the hadronic vacuum polarization piece of the muon g – 2. We test different types of electromagnetic and weak form factors and show that both, the Gounaris-Sakurai and a dispersive-based approach, describe accurately z lepton and e+e- data (less when KLOE measurements are included in the fits) and comply reasonably well with analyticity constraints. From these results we obtain the isospin-breaking contribution to the conserved vector current (CVC) prediction of the BR(z -> vz) and to the 2hadronic vacuum polarization (HVP) contribution to the muon g – 2, in agreement with previous determinations and with similar precision. Our results abound in the utility of using tau data-based results in the updated data-driven prediction of the muon g – 2 in the Standard Model.
