This series of three lecture will deal with two basic notions that are encountered in many different soft matter systems; geometric frustration and handedness. The first two lectures will focus on geometric frustration. We will introduce different kinds of geometric frustration, and discuss different possible strategies of resolving the resulting frustration, emphasizing differences between loc...

Antisocial behavior and aggression are prominent symptoms in several psychiatric disorders including antisocial personality disorder. An established precursor to aggression is a frustrating event, which can elicit anger or exasperation, thereby prompting aggressive responses. While some studies have investigated the neural correlates of frustration and aggression, examination of their relation ...

Frustration index is a key measure for analysing signed networks that has been underused due to its computational complexity. We use an optimisation-based method to analyse frustration as a global structural property of signed networks under different contexts. We provide exact numerical results on social and biological signed networks as well as networks of formal alliances and antagonisms bet...

Effects of anger induction procedures such as frustration and harassment on cardiovascular reactivity have been demonstrated in a wide range of experimental situations. Similarly, heightened cardiovascular reactivity has been associated with a diverse range of tasks involving active coping, competition and interpersonal interaction. The present study sought to directly compare the relative effe...

Despite the abundance of research linking frustration with prejudice, no research has examined the moderating role of personality. Two studies tested the prediction that narcissism would moderate the link between frustration and prejudice against immigrants in that individuals high in narcissism would show a stronger association than others. In Study 1 (n = 156), participants completed online s...

We consider the two-dimensional uniformly frustrated XY model in the limit of small frustration, which is equivalent to anXY system, for instance a Josephson junction array, in a weak uniform magnetic field applied along a direction orthogonal to the lattice. We show that the uniform frustration (equivalently, the magnetic field) destabilizes the line of fixed points which characterize the crit...

We examine the theory of micromagnetics developed by W. F. Brown. We show that in the case often considered, with exchange energy omitted, the minimum of the free energy is not attained for uniaxial materials but is attained for cubic materials. A study of the minimizing sequences reveals that these accurately model many features of observed domain structure. Finally, we reexamine the so-called...

Let $G$ be a connected graph with minimum degree $delta$ and edge-connectivity $lambda$. A graph ismaximally edge-connected if $lambda=delta$, and it is super-edge-connected if every minimum edge-cut istrivial; that is, if every minimum edge-cut consists of edges incident with a vertex of minimum degree.In this paper, we show that a connected graph or a connected triangle-free graph is maximall...

ing methods, we still experience frustrating situations for patients and even for doctors. Accordingly studies should be continued. Although the efficacies of the drugs and of the administration methods are the key points, practical points, such as the planned timetable and schedules, could be obstacles to bowel cleansing. In short, frustration still exists in bowel preparation. A tailored appr...

Psychological considerations suggest that the omission of rewards in humans comprises two effects: first, an allocentric effect triggering learning and behavioural changes potentially processed by dopaminergic neurons according to the prediction error theory; second, an egocentric effect representing the individual's emotional reaction, commonly called frustration. We investigated this second e...
