A narrow-band tunable injection-seeded pulsed titanium:sapphire laser system has been developed for application in high-resolution spectroscopic studies at the fundamental wavelengths in the near infrared as well as in the ultraviolet, deep ultraviolet, and extreme ultraviolet after upconversion. Special focus is on the quantitative assessment of the frequency characteristics of the oscillator-...

abstract We review how external magnetic fields act as perfect probes of the non-abelian nature of the electroweak theory.

Anomalous transport of heat and particles is known to be a key issue for fusion devices. In the present paper the anomalous transport of fast ions is investigated. High transit frequencies of the fast ions lead to the assumption that there is only very weak interaction with the low-frequency turbulence. However, our results indicate a significant fast ion particle transport due to the turbulenc...

Graft-versus-host disease (GVHD) is a common complication of bone marrow transplantation (BMT) that can be classified as acute or chronic. Chronic GVHD, which usually occurs more than 3 months after BMT, includes typical lichenoid or sclerodermatous lesions. Psoriasiform eruption is a rare clinical manifestation of chronic GVHD, and there have been no reports of psoriasiform chronic GVHD associ...

Although psoriasis and bullous diseases are considered to be completely different disease entities, the literature has reported a few cases of psoriasis associated with bullous diseases, most of which are bullous pemphigoid. In limited cases, pemphigus foliaceus has also been reported in association with psoriasis. In most of them, pemphigus lesions usually developed on an untreated patient wit...

Lichen nitidus (LN) is an uncommon chronic inflammatory skin disease composed of numerous, tiny, shiny, flesh-colored papules that are predominantly observed on the chest, abdomen, glans penis and upper extremities. The distribution of LN is most often localized, but in some cases it can become generalized. Because LN tends to be asymptomatic and presents spontaneous resolution within several y...

Pustular psoriasis of pregnancy (PPP) is a life-threatening condition for both the pregnant mother and fetus, and must be efficiently and accurately diagnosed and treated. This condition has historically been classified as a unique, separate dermatosis of pregnancy. However, current opinion and data suggest that it may be a variant of generalized pustular psoriasis. PPP typically occurs in the ...

INTRODUCTION Lymphomatoid papulosis is a chronic benign disease which may be associated with malignant lymphomas. This case illustrates the relapsing and remitting nature of both lymphomatoid papulosis and its potential of developing cutaneous T-cell lymphoma and narrow-band ultraviolet B (NB-UVB) phototherapy as a new modality of treatment of early-stage mycosis fungoides in these patients. ...
