Table S1 compiles the principal analytical and semi-analytical studies addressing steady-state groundwater flow into open excavations beneath thin retaining structures (cofferdams). This synthesis is intended to place the present work within its historical and methodological context and to make explicit the gap that motivates it. Studies are listed in chronological order; where a contribution is known mainly through a later compilation, both the original work and the source in which it was reported are indicated. For each study, the table summarizes the reference, the cofferdam geometry considered, the methodology adopted (analytical, analogue, or numerically verified), and its main contribution. Four descriptors then indicate whether the formulation accounts for the excavation, for anisotropy of the hydraulic conductivity, and for a layered (heterogeneous) soil profile, and whether the flow domain is treated as bounded laterally and at depth; a final column reports the form in which the results are presented (mathematical expression, design curves, or tables). As the table shows, only a small number of works consider layered media, and none simultaneously incorporate layering and anisotropy under a bounded-domain assumption—precisely the configuration addressed in this study.

Organic and hybrid solar cells are emerging photovoltaic technologies that may reach the market in the coming years. Nevertheless, the process of charge photogeneration and transport is not completely understood. CH3NH3PbI3 perovskite solar cells have reached PCE > 23%, but its stability is poor, with lifetimes lower than one year. The crystalline structure of the active layer determines the charge photogeneration and transport, and therefore affects its power conversion efficiency (PCE) and the operational stability of the device. The addition of small molecules (amino valeric acid) is changing the structure of the material and providing longer lifetimes. Also, if part of the Pb atoms is replaced by Mn, a long range magnetic order develops at low temperatures (Tc around 25K). We plan to determine the atomic and magnetic structure of CH3NH3PbI3 solar cells by neutron diffraction and study its thermal dependence. The perovskite structure and its distortion at several temperatures ranging from 10K to 300K will be measured. The long range magnetic structure (RKKY interaction) when part of the Pb is replaced by Mn will be studied as a function of temperature and the content of Mn.

The data was collected by 10 sensor nodes, each one comprising an ambient light sensor (SEN0390), a soil moisture sensor (Gravity IP65), and a combined air temperature and relative humidity sensor (CHT8305)., Sensor data on soil moisture, ambient light, and air temperature from a greenhouse in Cartagena, Spain., This work was supported by the grant PID2023-148214OB-C21 funded by MICIU/AEI/10.13039/501100011033 and by FEDER/EU. This work was also supported by the grant PCI2024-153485 funded by MICIU/AEI /10.13039/501100011033 and by the European Union. This research was also funded by the PRIMA Programme under Grant Agreement No. 2431 (FUSION: Comprehensive and sustainable solution to minimize food loss and waste and promote food security in the Mediterranean region). The work of Francisco-Jose Alvarado-Alcon was supported by the Spain’s Ministry of Universities under Grant FPU22/00316.

This document contains the template used for the survey "Analysis of the gender gap in Engineering and Architecture studies" and the summary of responses.
