Electrons backscattered from crystals can show Kikuchi patterns: variations in intensity for different outgoing directions due to diffraction by the lattice. Here, we measure these effects as a function of their energy loss for 30 keV electrons backscattered from silicon. The change in diffraction contrast with energy loss depends strongly on the scattering geometry. At steep incidence on the s...

We propose a two-country growth model of intermediate businessservices trade that captures the role of time zone differences. It is shown that a time-saving improvement in intermediate businessservices trade involving production in different time zones can have a permanent impact on productivity. ∗E-mail addresses: [email protected] (Kikuchi), [email protected] (Marjit).

BACKGROUND Kikuchi-Fujimoto disease is a self-limited clinicopathologic entity that is increasingly recognized worldwide. Kikuchi-Fujimoto disease is characterized by cervical lymphadenopathy occurring in young adults. Neurologic involvement is rare, and testitis directly caused by Kikuchi-Fujimoto disease has not yet been reported. CASE PRESENTATION A 19-year-old man was brought to our clini...

Kikuchi-Fujimoto disease is an idiopathic histiocytic necrotizing lymphadenitis with an autoimmune component triggered by the involvement of CD8 cytotoxic T lymphocyte due to a genetic predisposition. Cases are diagnosed more frequently in female patients, especially in young adults, in all races, more commonly in East Asia, and only isolated in Europe and America. We present the case of a 51-y...

The orientation dependence of thin-crystal lattice fringes can be gracefully quantified using fringe-visibility maps, a direct-space analog of Kikuchi maps Nishikawa and Kikuchi, Nature London 121, 1019 1928 . As in navigation of reciprocal space with the aid of Kikuchi lines, fringe-visibility maps facilitate acquisition of crystallographic information from lattice images. In particular, these...

Purpose We present a patient with systemic lupus erythematosus with significant vaso-occlusive retinal findings mimicking antiphospholipid antibody syndrome, who developed Kikuchi-Fujimoto disease. Observations Our patient was initially diagnosed with systemic lupus erythematosus with antiphospholipid antibody syndrome given consistent serologic markers and profound retinal vascular ischemia....

Cervical lymphadenopathy can be developed from various causes such as viral infection, bacterial infection, Kikuchi-Fujimoto disease, tuberculosis, malignancy, and reactive changes. In patients who have malignancy, metastatic lymphadenopathy is possible but it is rare that other concomitant diseases are in the same lymph node. We experienced a case of coexistence of Kikuchi necrotizing lymphade...

Kikuchi-Fujimoto disease is a self-limited benign condition of unknown etiology characterized by cervical lymphadenopathy, fever, and leucopenia. An autoimmune hypothesis has been suggested and an association with systemic lupus erythematosus, Sjogren's disease, and antiphospholipid syndrome has been noted. We report a 27-year-old male who presented for evaluation of weakness and he was diagnos...
