From glass formation to icosahedral ordering by curving three-dimensional space [PDF]
, 2017 Geometric frustration describes the inability of a local molecular arrangement, such as icosahedra found in metallic glasses and in model atomic glass-formers, to tile space.

Reduced dimensionality in layered quantum dimer magnets: Frustration vs. inhomogeneous condensates
, 2007 Motivated by recent experiments on BaCuSi2O6, we investigate magnetic excitations and quantum phase transitions of layered dimer magnets with inter-layer frustration. We consider two scenarios, (A) a lattice with one dimer per unit cell and perfect inter-

La frustració de l'estudiant en línia. Causes i accions preventives
Digithum, 2005 La frustració de l'estudiant en línia originada per situacions problemàtiques greus o repetides és un fet que no s'estudia prou a hores d'ara. De fet, les conseqüències de la frustració de l'estudiant poden representar una càrrega per a tots els agents ...

Combined effect of frustration and dimerization in ferrimagnetic chains and square lattice
, 2000 Within the zero-temperature linear spin-wave theory we have investigated the effect of frustration and dimerization of a Heisenberg system with alternating spins $s_{1}$ and $s_{2}$ on one- and two-dimensional lattices.

Surveying biomolecular frustration at atomic resolution
Nature Communications, 2020 To function, biomolecules require sufficient specificity of interaction as well as stability to live in the cell while still being able to move. Thermodynamic stability of only a limited number of specific structures is important so as to prevent ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Introduction We developed MedSupport, a multilevel medication adherence intervention designed to address root barriers to medication adherence. This study sought to explore the feasibility and acceptability of the MedSupport intervention strategies to support a future full‐scale randomized controlled trial.

From Spin Glasses to Negative-Weight Percolation
Entropy, 2019 Spin glasses are prototypical random systems modelling magnetic alloys. One important way to investigate spin glass models is to study domain walls. For two dimensions, this can be algorithmically understood as the calculation of a shortest path, which ...

Molecular Oncology, EarlyView.AZD9291 has shown promise in targeted cancer therapy but is limited by resistance. In this study, we employed metabolic labeling and LC–MS/MS to profile time‐resolved nascent protein perturbations, allowing dynamic tracking of drug‐responsive proteins. We demonstrated that increased NNMT expression is associated with drug resistance, highlighting NNMT ...
