Design of Miniaturized SIW Filter Loaded with Improved CSRR Structures
Electronics (Switzerland), 2023 In recent years, Split-Ring Resonators (SRRs) and Complementary Split-Ring Resonators (CSRRs) have gained significant attention for their unique electromagnetic properties, such as negative permeability and negative permittivity, making them promising ...

Archives of Dermatology, 1949
In 1924 Letterer 1 described a disease characterized by enlargement of the spleen and the liver, associated with anemia and a purpuric eruption. The patient in Letterer's case was an infant 6 months old, who died within four days after admission to the hospital.

Pediatrics, 1971
I have read with interest the article of Dr. D. C. Mauger on Letterer-Siwe's disease complicated with intravascular coagulation (Pediatrics, 47: 435, 1971). I think that the possibility of intravascular coagulation has not been proven conclusively in the absence of measurement of some key factors, especially with the degree of hepatosplenomegaly this ...

SIW fed dielectric resonator antennas (SIW-DRA)
2006 IEEE MTT-S International Microwave Symposium Digest, 2006A novel feeding structure using substrate integrated waveguide (SIW) technique for dielectric resonator antenna (DRA) is presented in this paper. After making studies by simulations for the proposed SIW fed DRAs, the antennas are fabricated using standard PCB process and measured by vector network analyzer (VNA).

Letterer-siwe disease in adults
Cancer, 1989Histiocytosis X (HX) is a rare disorder of histiocytic proliferation characterized by a broad spectrum of clinicopathologic disease. An unusual case of Letterer-Siwe disease (LSD) or subacute disseminated HX in a 71-year-old woman is presented. The patient had a 3-year history of splenomegaly before skin lesions developed.

Letterer-Siwe disease in an octogenarian
Journal of the American Academy of Dermatology, 1984The case of an 81-year-old woman suffering for about 1 year from a typical form of Letterer-Siwe disease (LSD) is reported. The only important systemic involvement was hepatosplenomegaly. The patient was treated with steroids and vinblastine and then with thymopoietin pentapeptide.

Cutaneous Letterer-Siwe Disease
Archives of Pediatrics & Adolescent Medicine, 1969Letterer-Siwedisease is a nonlipid reticuloendotheliosis of unknown etiology and is usually grouped with Hand-Schuller-Christian disease and eosinophilic granuloma as components of histiocytosis X. 1 It typically occurs in infancy and, clinically, is the most generalized and serious of these conditions.

Proceedings of the 2014 ACM SIGSAC Conference on Computer and Communications Security, 2014
The human element is often considered the weakest element in security. Although many kinds of humans interact with systems that are designed to be secure, one particular type of human is especially important, the security information worker. Security information workers include software developers, system administrators, and intelligence analysts. This

Congenital Letterer-Siwe Disease
Beiträge zur Pathologie, 1974Summary An acute fulminating case of Letterer-Siwe disease in a newborn female is reported. The infant died 11 days after birth. Autopsy findings revealed advanced Letterer-Siwe disease indicating that the illness had its origin during intrauterine life.

2014 IEEE MTT-S International Microwave Symposium (IMS2014), 2014
A compact diplexer fabricated on substrate-integrated waveguide (SIW) technology is presented. The diplexer is a coupled-resonator network with no additional elements such as power dividers, composed exclusively of six SIW resonators coupled through inductive irises, with one transmission zero at each channel that improves the selectivity.
