Neural operators solve inverse problems for constitutive model discovery

Moritz Flaschel · Burigede Liu · Ellen Kuhl

Characterizing the mechanical response of materials traditionally requires solving optimization problems in which model parameters are calibrated or trained to minimize the discrepancy between model predictions and experimental data. This process can be computationally expensive and time-consuming. To overcome this lim...

Rapid identification of chemical warfare agents using hyper-fast gas chromatography combined with dual polarity ion mobility spectrometry

Alexander Nitschke · Maria Allers · Gian-Luca Gloeden · Moritz Hitzemann · y 5 más

The analytical performance of ion mobility spectrometry (IMS) is frequently enhanced by coupling with gas chromatography (GC). This hyphenated approach mitigates chemical cross-sensitivities and competitive ionization effects, and enables the distinct separation of analytes even in the presence of complex background ma...

Impact of plasma treatment on Ce(IV)-O-clusters and Ce(IV)-MOFs

Hauke ROHR · Tim GRAUPNER · Alexander QUACK · Anastasia MOLOKOVA · y 1 más

The structural integrity of {CexZr6-xO4(OH)4} clusters (x = 6, 1) deposited inside the pores or being integral part of the metal-organic framework (MOF) upon interaction with nonthermal plasma (NTP) will be determined. Ce K-edge extended X-ray absorption fine structure (EXAFS) and powder X-ray diffraction (PXRD) will b...

Lymph node-targeted mRNA delivery of fine-tuned peptide-nanocomplexes for SARS-CoV-2 Vaccination

Hayoon Jeong · Gookjin Yoon · Dong Woo Lee · Hansang Yu · y 12 más

Messenger RNA (mRNA) vaccines require efficient delivery systems to reach antigen-presenting cells (APCs). Lipid nanoparticles (LNPs) are a standard delivery carrier. However, LNPs often accumulate in the liver and exhibit transient protein expression. These limitations can restrict their safety and immunogenic potenti...

Voids in liquids: Peculiarities of molecular dynamics simulation of fluid systems

Fomin, Yu. D.

Molecular dynamics is a powerful tool to investigate the properties of fluid systems. However, a correct interpretation of the results of simulations is required. In particular, some simulations show appearance of large voids in liquids, which contradicts our common sense on what is liquid. In the present paper we disc...

Low Mach number limit of non-isentropic inviscid elastodynamics with general initial data

Jiawei Wang · Junyan Zhang

We prove the incompressible limit of non-isentropic inviscid elastodynamic equations with {\it general initial data} in 3D half-space. The deformation tensor is assumed to satisfy the neo-Hookean linear elasticity and degenerates in the normal direction on the solid wall. The uniform estimates in Mach number are establ...

Structural studies of RNA Polymerase from P. aeruginosa

Sheenu KAKKAR · Hok Sau KWONG · Eaazhisai KANDIAH

We would like to solve the high resolution structure of P.aeruginosa RNAP in both its apo-form and its holo-form containing sigma-28 and DNA using cryo-EM

Consistent Community Detection in Multi-Layer Networks with Heterogeneous Differential Privacy

Yaoming Zhen · Shirong Xu · Junhui Wang

As network data has become increasingly prevalent, a substantial amount of attention has been paid to the privacy issue in publishing network data. One of the critical challenges for data publishers is to preserve the topological structures of the original network while protecting sensitive information. In this paper,...

3D lattice strain quantifiaction in neutron irradiated steels for fusion energy

Phoebe CUTTS · John COOPER · Cai BIAO · Lucy FITZGERALD · y 3 más

Iron-chromium (FeCr) alloys are a top candidate for development as structural materials within Demonstrator fusion reactors. Examples of already developed materials are Eurofer97 (E97), F82H, Fe-14Cr-YWTi oxide dispersion strengthened (ODS) alloys. In the latter, the addition of Y2O3 nanoparticles into these alloys imp...
