Protein folding is a central problem in biological physics. Energetic roughness is an important aspect that controls protein-folding stability and kinetics. The roughness is associated with conflicting interactions in the protein and is also known as frustration. Recent studies indicate that an addition of a small amount of energetic frustration may enhance folding speed for certain proteins. I...
The term "frustration" in the context of magnetism was originally used by P. W. Anderson and quickly adopted for application to the description of spin glasses and later to very special lattice types, such as the kagomé. The original use of the term was to describe systems with competing antiferromagnetic interactions and is important in current condensed matter physics in areas such as the des...
BACKGROUND Some patients receiving mechanical ventilation experience an intensified need to communicate while their ability to do so is compromised as the endotracheal tube prevents speech. Although the use of a communication board to enhance communication with such patients has been suggested, few descriptive or empirical studies have addressed the content and format of these devices or of pat...
background: transition into parenthood is a major developmental life event and is very significant because development in infanthood is affected by the transition process of mothers parenting an infant. this study aimed to develop the assessment tool for transition process of high risk infant’s caregiver in korea. methods: the participants were 246 mothers of premature infant born with gestatio...
We solve a model that takes into account entropic barriers, frustration, and the organization of a protein-like molecule. For a chain of size M , there is an effective folding transition to an ordered structure. Without frustration, this state is reached in a time that scales as M, with λ ≃ 3. This scaling is limited by the amount of frustration which leads to the dynamical selectivity of prote...
the aim of this study was to determine the effectiveness of physical practices on the reduction of slow-pace children's aggression. for this purpose, 20 guidance school students with slow pace were selected through simple random sampling. they were divided into experiment (10 persons) and control (10 persons) groups. rosenzweig frustration scale was administered to both groups as the prete...
a phase-locked loop (pll) based frequency synthesizer is an important circuit that is used in many applications, especially in communication systems such as ethernet receivers, disk drive read/write channels, digital mobile receivers, high-speed memory interfaces, system clock recovery and wireless communication system. other than requiring good signal purity such as low phase noise and low spu...
We studied the spin arrangement in ultrathin antiferromagnetic Mn films in contact with a ferromagnetic Fe(001) substrate using spin-polarized scanning tunneling microscopy. Mn shows a layerwise antiferromagnetic order on Fe(001). In regions where Mn overgrows Fe steps, a frustration of the antiferromagnetic order occurs which is similar to a 180 degrees domain wall. This topologically enforced...
The expanded classical Kitaev-Heisenberg model on a honeycomb lattice is investigated with the next-nearest-neighboring Heisenberg interaction considered. The simulation shows a rich phase diagram with periodic behavior in a wide parameter range. Beside the double 120° ordered phase, an inhomogeneous phase is uncovered to exhibit a topological triple-vortex lattice, corresponding to the hexagon...
