Origin of Symmetric Dimer Images of Si(001) Observed in Low-Temperature STM [PDF]
It has been a long-standing puzzle why buckled dimers of the Si(001) surface appeared symmetric below 20 K in scanning tunneling microscopy (STM) experiments. Although such symmetric dimer images were concluded to be due to an artifact induced by STM measurements, its underlying mechanism is still veiled.

Accurate measurement and assessment of the QT interval [PDF]
QT measurement should be included as part of the systematic interpretation of the electrocardiogram (ECG). Accurate measurement and interpretation of the QT interval will help to identify potentially fatal long QT syndrome (LQTS).

Long QT Syndrome: Genetics and Future Perspective
Long QT syndrome (LQTS) is an inherited primary arrhythmia syndrome that may present with malignant arrhythmia and, rarely, risk of sudden death. The clinical symptoms include palpitations, syncope, and anoxic seizures secondary to ventricular arrhythmia,

BACKGROUND Long QT syndrome is a potentially lethal yet highly treatable cardiac channelopathy. Although β-blocker therapy is standard for most patients, concomitant therapy with sodium channel blockers, like mexiletine, is often utilized for patients ...

EPR Paradox,Locality and Completeness of Quantum Theory [PDF]
The quantum theory (QT) and new stochastic approaches have no deterministic prediction for a single measurement or for a single time -series of events observed for a trapped ion, electron or any other individual physical system. The predictions of QT being of probabilistic character apply to the statistical distribution of the results obtained in ...

Acquired Long QT Syndrome and Electrophysiology of Torsade de Pointes
Congenital long QT syndrome (LQTS) has been the most investigated cardiac ion channelopathy. Although congenital LQTS remains the domain of cardiologists, cardiac electrophysiologists and specialised centres, the much more frequently acquired LQTS is the

QT Adaptation and Intrinsic QT Variability in Congenital Long QT Syndrome
Background Increased variability of QT interval (QTV) has been linked to arrhythmias in animal experiments and multiple clinical situations. Congenital long QT syndrome (LQTS), a pure repolarization disease, may provide important information on the ...

Selective acquired long QT syndrome (saLQTS) upon risperidone treatment
Background Numerous structurally unrelated drugs, including antipsychotics, can prolong QT interval and trigger the acquired long QT syndrome (aLQTS). All of them are thought to act at the level of KCNH2, a subunit of the potassium channel.
