Iffy imidazoles: misplaced hydrogen atoms and undetected disorder

Borderline personality disorder often goes undetected.

Borderline personality disorder (BPD) is a complex mental disorder characterised by mood instability, impulsivity, relationship difficulties and disturbed self-image. There is a pervasive pattern of emotional instability, impulsive aggression, repeated self-harm and chronic suicidal tendencies often associated with suicide attempts. Some patients are able to sustain a certain level of social an...

Iffy predictions and proper expectations

What individuates the speech act of prediction? The standard view is that prediction is individuated by the fact that it is the unique speech act that requires future-directed content. We argue against this view and two successor views. We then lay out several other potential strategies for individuating prediction, including the sort of view we favor. We suggest that prediction is individuated...

Microwave ionization of hydrogen atoms

Figure 1: Fraction of ionized hydrogen atoms as a function of microwave frequency , measured in units of level spacing for initially excited level ; data are obtained by numerical simulations of classical (circles) and quantum (crosses) evolution; one-photon ionization threshold is marked by (from [3]) Dima Shepelyansky (2012), Scholarpedia, 7(1):9795. doi:10.4249/scholarpedia.9795 revision #12...

Electron diffraction sees hydrogen atoms

Modeling and Analysis of Hydrogen Atoms

Hydrogen atoms are elusive seen from the point of view of the X-ray crystallographer. But they are also extremely important, being involved in a wealth of intermolecular interactions and thereby defining the way molecules interact. Most experimental charge density studies are performed on compounds containing hydrogen, yet a commonly accepted strategy to deal with these elusive but so important...
