description: Programmed death-ligand 1 (PD-L1) is an important biomarker increasingly used as a predictive marker in breast cancer immunotherapy. Immunohistochemical quantification is the current standard assessment method; however, it presents challenges in terms of time, cost, and reliability. Hematoxylin and eosin (H&E) staining is a routine staining method in cancer pathology, known for being easily accessible and consistently reliable. Deep learning has demonstrated the potential to predict biomarkers in cancer histopathology. This study uses a weakly supervised, multiple instance learning(MIL) approach to predict PD-L1 expression from H&E-stained images using deep learning techniques. In the internal test set, the TransMIL method achieved an area under curve (AUC) of 0.833, and in an independent external test set, it achieved an AUC of 0.799. Additionally, since RNA sequencing results indicate a threshold that makes H&E pathology images separable, we also conducted predictions on the public TCGA-TNBC database, achieving an AUC of 0.721. This demonstrates that the Transformer-based TransMIL model can effectively capture highly heterogeneous features within a MIL framework, exhibiting strong cross-center generalization ability. Our study shows that appropriate deep learning techniques can enable effective PD-L1 prediction on datasets with limited data and across regions and centers. This not only demonstrates the significant potential of deep learning in pathological AI but also provides a valuable reference for the rational and efficient allocation of medical resources.

title: ITABAG: 3D structures of macromolecules related to human health

description: The ITABAG includes structural biologists from Universities, the National Research Council and Hospital research centres in Italy. The laboratories take advantage of single crystal and small angle X-ray diffraction methods to study the structure-function relationships in various macromolecules. A unifying factor for the clear majority of the macromolecules under study is their relationship to human health, either directly, being human proteins involved in some disease, or indirectly, as proteins expressed by human pathogens and validated as potential pharmacological targets. Other projects investigate basic chemical processes, the study of plant viral proteins, or aim at characterising macromolecules with potential biotechnological applications including drug delivery.

title: Exploring the dynamic nature of OCP crystals by combined use of diffraction and in crystallo spectrophotometry at room-temperature

description: The photoactive Orange Carotenoid Protein (OCP) is a reversible photoswitch which serves photoprotection in cyanobacteria (Wilson et al. 2006). OCP is
functionalized by a keto-carotenoid pigment which, in the presence of a blue-green photon, is able to induce conformational changes resulting in a photoactivated
state capable of quenching an excess of absorbed light energy. Preliminary experiments offered first evidence that dehydration of OCP crystals lead to the trapping of
a pre-activated state. The very goal of our experiment is to verify this hypothesis by simultaneous collection of diffraction and spectroscopic data from crystals at
room-temperature and at varied levels of humidity

title: Micro X-ray Insights into Deformation Mechanisms in Flexible Crystals

description: Flexible crystals refer to a class of crystalline materials that maintain their structural integrity and partial or total functionality when subjected to bending or deformation. These materials have garnered significant attention in recent years due to their potential applications in the fields of flexible electronics, photonics, and sensing technologies. The proposed experiment is designed to examine the internal structural dynamics of these crystals as they undergo bending. Utilizing micro X-ray diffraction, we aim to elucidate the changes within the crystals' architecture. This analysis will not only reveal the underlying deformation mechanisms but also provide insights into how these materials can be leveraged for sensing applications. By understanding the structural responses to mechanical stress, we can pave the way for the development of innovative sensing technologies that capitalize on the unique properties of flexible crystals.

title: Decipering the nature of active sites on Ir-based oxygen evolution nanocatalysts with operando X-ray total scattering

description: In this experiment, we will investigate operando the local structure of Ir-based nanocatalysts during oxygen evolution reaction using high energy X-ray total scattering. The samples (IrOx, IrCu, Ir, Ir/Ta-doped tin oxide) will be mounted in a X-ray transparent electrolysis cell developed by the ID31 beamline.

Especially, we will focus also on the structural changes triggered by low potential excursion of the anode, which are expected at the startup-shutdown of the device.

title: Chain Conformation of Liquid-Crystalline Bottlebrush Polymers in Solution: Insights from SAXS Measurements

description: During the allocated beamtime, we aim to investigate the chain conformation of bottlebrush (BB) polymers and copolymers capable of forming liquid-crystalline (LC) phases. The LC behavior of these BBs arises from hydrogen bonding within the side chains, which is expected to influence the persistence length of the polymer backbone. By employing small-angle X-ray scattering (SAXS), we will explore how hydrogen bonding modulates the chain conformation in solution, potentially creating conditions favorable for LC phase formation. These findings will contribute to a deeper understanding of the structural properties of LC bottlebrush polymers and their self-assembly behavior.

title: Investigating the effect of insulin administration on the brain of Alzheimer's disease mice

description: A correlation between Alzheimer's disease (AD), insulin resistance, and glucose metabolism has been postulated. Beyond its role in blood sugar regulation, insulin exhibits potential neuroprotective effects, and its resistance in the brain may be linked to accelerate cognitive aging and AD. Pilot clinical studies reveal that insulin administration improves memory performance; it has been hypothesized that insulin acts by enhancing the synaptic plasticity and conformationally disrupting the brain amyloid beta plaques. Thus, this study aims to evaluate the effects of insulin administration - a candidate therapeutic intervention for dementia - on the structure of amyloid beta plaques, the neuronal and capillary network and on the surrounding microenvironment in the brain of AD mice by comparing insulin-treated AD mice with untreated AD mice and healthy wild-type mice as controls.

title: HUB Proposal: Human Organ Atlas Hub (HOAHub)

description: This HOAHub will create a physical and virtual Hub which uses HiP-CT to scan whole human organs with local cellular resolution, producing a “Human Organ Atlas in Health and Disease”. It will bridge clinical imaging (centimetre scale) to molecular modalities (nanometer scale), providing unprecedented insights into our bodies, helping cure or mitigate diseases from neuro-degeneration to cancer. The HOAHub will bring together interdisciplinary groups to produce the novel experimental and computational technologies needed to analyse and interpret the scale-bridging data. By transforming HiP-CT into an efficient tool, HOAHub will enable the clinical impact of synchrotron imaging to be realised. Through these scientific and technical efficiencies, HOAHub will not only advance biological, computational and medical fields, it will provide anatomical training resources and a new Gold Standard for validating CT, MRI and 3D histology, inspiring new techniques and real-world clinical insights.

title: In-situ XAS measurements as a new approach to probe metal extraction from magmas: Distribution of Cu and Zn in fluid+melt systems to 1200°C

description: The aim of the proposed experiments is to quantify the distribution of Cu and Zn between fluids and silicate melts to evaluate the efficiency of their extraction upon the degassing of arc magmas. Such experimental data are necessary to develop thermodynamic models of degassing and ore-forming processes and ultimately improve our predictive capacities for new mineral resources that are necessary to the transition to cleaner energies.

title: Investigation on the unexpected capacitive behaviour of Pt(111) in acidic medium with SRXRD coupled with ab initio calculations

description: The goal of the present project is to get the atomic/electronic description of the electrochemical interface for the archetypal system Pt(111) as a function of the pH and the concentration of the perchlorate solution. Indeed, an unexplained capacitive behaviour has been observed by several authors, but never explained, due to the lack of experimental probes of the interfacial charges. 
Beyond this system, the expected results will allow to improve the ab initio theoretical description of the SRXRD spectra and make more and more realiable our new approach coupling SRXRD and ab initio simulation. This will be a major contribution to the up to now lacking experimental evidence of the electrochemical interface charge distribution.

title: Time-resolved X-ray solution studies of pH induced conformational changes in a proton-sensitive potassium channel

description: We will use time-resolved X-ray solution scattering (TR-XSS) to study the pH sensitive ion channel KcsA. An earlier experiment at ID09 (LS-3224) was very successful, with changes in the X-ray scattering observe when UV light was used to release caged protons, thereby jumping the sample from pH 7 (neutral) to pH 4 (acidic). We will build from this earlier experiment to test if point-mutations that inactivate the enzyme also suppress the observed conformational changes. Since the release of photocaged protons is very fast, we will also collect data for early-microsecond delays, aiming to measure the rise of the pH induced conformational change in KcsA. Finally, we will reproduce the pH induced conformational change in KcsA using a mixing flow-cell, with the goal of developing a generic approach to TR-XSS. Our studies of KcsA mutants will provide new structural insight into the transition from a closed to an open conformation of this highly studied potassium channel.

title: Studying the (de-)vitrification, aging, and sub-Tg relaxation behavior of metallic glasses via slow temperature scanning XPCS

description: We aim to use slow temperature scanning XPCS to study the sub-Tg relaxations, aging effects, and the (de-)vitrification behavior of two archetypical metallic glass formers. A novel fitting approach recently developed by our groups will help to separate different decorrelation mechanisms, further allowing to identify and separate different underlying types of atomic motions. To do so, the fast acquisition time and excellent signal-to-noise ratio available at the fourth generation synchrotron ESRF are substantially needed.

title: Bio-inspired Water-Free Synthesis of Amino Acid-incorporated MAPbBr3 hybrid Perovskites: Correlating Lattice strains to Optical Properties

description: Our research draws inspiration from biogenic calcite's ability to incorporate biomacromolecules. Through ESRF experiments, we demonstrated the incorporation of amino acids (AAs) into various materials, including methylammonium lead bromide perovskites (MAPbBr3), widening their band gap and improving humidity stability critical for solar cells. Herein, we propose investigating for the first time water-free AA incorporation into MAPbBr3. Our focus is understanding how growth kinetics influence AA incorporation and their impact on crystal structure and optical properties. We'll grow MAPbBr3 crystals in non-water environments with 10 AAs, characterizing their structure via HR-PXRD on ID22. Additionally, we'll analyze the correlation between AA concentration and induced lattice distortions, linking them to changes in optical band gap. We believe this research will pave the way for bio-inspired enhancements in optoelectronic materials.

title: Probing the d band structure of Pd and Cu for CO2 hydrogenation

description: With the increase in CO2 emission, the conversion and utilization of CO2 have emerged as a research frontier. Herein, we prepared a series of Pd-Cu bimetallic catalysts by exploiting the activation ability of Pd for hydrogen, which significantly improved the CO2 conversion with H2 at low temperatures. The excellent catalytic performance can be attributed to the interfacial structures formed between Pd-Cu species and oxygen vacancies (VO) on the CeO2 surface, which can determine the activation of CO2, H2 and the formation of intermediate species. Here, we apply for an in situ Pd L3 edge, Ce L3 edge and Cu K edge valence-to-core (Vtc)- RIXS study to follow the dynamics of the Pd-Cu d band with the evolution of the Ce4f-O2p bond structure of CeO2 and identify surface reactant adsorption under RWGS reaction conditions. This study utilizes the uniqueness of the in situ tender RIXS capability at ID26 and will provide a comprehensive understanding of CO2 hydrogenation.

title: Development of in-situ high-energy X-ray diffraction capability with flash scanning calorimetry.

description: This LTP aims at developing a new capability at ESRF combining in-situ high-energy X-ray diffraction with flash differential scanning calorimetry (FDSC). FDSC is an emerging technology that allows for the precise control of sample temperature and the measurement of calorimetric properties at heating/cooling rates of 10^4 K/s or above, several orders of magnitude higher than conventional calorimetry. Combining FDSC with high-energy X-ray diffraction will allow us to obtain detailed structural information on the atomic scale of systems in previously unprobed thermodynamic states. This new technique can be applied to a wide range of systems including but not limited to supercooled liquids, glasses (oxides, metallic glasses, chalcogenides, etc.), polymers, and phase change materials. The outcome of this LTP can benefit a large user community from the fields of physics, chemistry, and materials science and engineering, among others, and expand ESRF’s user base.

title: X-ray Absorption Spectroscopy study of local structural changes in ionic aqueous solutions under high pressure and high temperature

description: Experimental data regarding the relationship between density and temperature and the local structural changes in the ion hydration environment in diluted aqueous solutions has long been desired. Such an information is essential for understanding possible transformations between octahedral and more complex hydration configurations occurring in the liquid and in salty ice phases. We propose to investigate the local structural changes in aqueous solutions of representative 3d metal elements (Fe and Cu) up to 15 GPa and 1000 K, using EXAFS refinement. We aim to obtain reliable quantitative data that is necessary for further understanding about the salt-water phase diagrams including the eutectic melting point depression as a function of pressure. The proposed research will have strong interdisciplinary implications on the understanding of fundamental processes which involve salty water under extreme conditions in astrophysics and applied geophysics.

title: Magnetic-field induced Charge Order Quantum Criticality in La2-xSrxCuO4

description: The nature and origin of charge order in high-temperature superconducting cuprates are still open questions. Recent measurements suggest that the long-range charge ordered phase emerges out of a broader regime characterized by short-range, and possibly dynamical, correlations. However, it remains unresolved whether the emergence develops through a quantum critical point or through a smooth crossover. As resonant soft x-ray scattering techniques have proved to be one of the most sensitive techniques to probe charge correlations in cuprates, here we propose to study charge order around optimal doping with the resonant inelastic x-ray scattering (RIXS) technique. We plan to add another dimension to the cuprate phase diagram by combining RIXS with application of magnetic field. It enables us to clarify whether the long-range charge order can be field induced, which would support or stay in opposition to the quantum critical point scenario.

description: This proposal aims at using inelastic x-ray scattering to study in detail the nuclear contribution to the spin-lattice hybrid excitation previously observed in the spinel GeCo2O4 by inelastic neutron scattering with polarization analysis. The goal is first to check its phononic nature, then track its dispersion and temperature dependence in order to confirm the presence of a spin-lattice coupling in this compound.
