Conformal Inference for Missing Data Under Multiple Robust Learning

Tang, Wenlu · Wang, Hongni · Zhou, Xingcai · Jiang, Bei · y 1 más

We develop a novel approach to tackle the common but challenging problem of conformal inference for missing data in machine learning, focusing on Missing at Random (MAR) data. We propose a new procedure Conformal prediction for Missing data under Multiple Robust Learning (CM--MRL) that combines split conformal calibrat...

XAFS study of the structural role of Zn in insulin polymorphs prepared under different physicochemical conditions

Alessandro PURI · Maria KATSIKINI · Fani PINAKIDOU

The main objective of the proposal is to investigate the structural role of Zn in human insulin (HI) polymorphs (hexamers adopting structures described as T6, R6, T3R3) using XAFS spectroscopy which provides the local bonding environment of this ion (tetrahedral / octahedral coordination, binding sites, distances to th...

Commissioning of a catalytic cell for the soft X-ray chamber.

VASYL MARCHUK

We are going to test a catalytic cell for the tender X-ray chamber at ID26. The experiment will be conducted without a beam. The cell will be heated to 700 °C (5 °C / min) with different X-ray windows (graphite, kapton) and different gases flowing inside: He, 1 % NH3, 5 % CH4, 4 % H2.

In-situ triggering and recording the liquid-liquid transition of metallic glass formers

Irene FESTI · Valerio DI LISIO · Klara OTTO · Jie SHEN · y 5 más

Liquid-liquid transitions (LLTs) are a fascinating process where one liquid transforms into another via a first-order transition. In metallic liquids, this usually occurs in the ultra-viscous supercooled state and is accompanied by an abnormal exothermic calorimetry signal and important structural changes at the medium...

In-situ temperature/strain-dependent SAXS/WAXS measurement of a thermo-responsive hydrogel with switchable micromorphology and optical prope

Xinxin HUANG · Shanming HU · Chen LIANG · Yuhuang FANG · y 3 más

We propose a temperature- and strain-dependent small-angle/wide-angle X-ray scattering (SAXS/WAXS) experiment to investigate the mesoscopic scale structural change in a thermo-responsive hydrogel system under heating/cooling cycles or deformations. Our hydrogel can respond remarkably to both temperature and strain, res...

Trimer quantum spin liquid candidate Ba4Ir3O10: magnetic excitations of a cluster Mott insulator

Enrico BERGAMASCO · Lara PAETZOLD · JULIA KUESPERT · Markus GRUENINGER

The iridate Ba4Ir3O10 hosts a quasi-2D network of trimers and has been discussed as an unusual quantum spin liquid. RIXS data have been explained in terms of a quasi-1D spinon continuum based on frustrated intra-trimer exchange. We acquired some RIXS data of Ba4Ir3O10 with 60 meV resolution upon commissioning at ID20,...

Structural mechanisms of protein for biomedical and biotechnological application: pathological processes, targeted therapies, and enzyme des

Lluís EIXERÉS · Santiago RAMON-MAIQUES · Clara MARCO · Hayden FISHER · y 1 más

We request the continuation of previous BAG MX-2650, created from the ESRF recommendation to merge several groups from south-east Spain. The team is intrinsically heterogeneous reflected in a diversity of research lines, focused on deciphering the molecular mechanisms of proteins and complexes involved in pathological...

Subcellular distribution and speciation of iron and manganese in pollen grains

Catherine CURIE · Tom LALOUM · Hiram CASTILLO · JULIEN COUTURIER (ORCID: 0000-0002-3807-457X) · y 1 más

Manganese (Mn) and iron (Fe) are essential micronutrients for plants, playing critical roles even in reproductive organs of plants, such as the pollen-bearing anthers. Our team has developed single-cell ICP-MS and metal staining methods, which, along with other researchers' work, have demonstrated that the accumulation...
