A package characterization technique using coplanar waveguide (CPW) probes and line–reflect–match (LRM) calibrations for surface-mountable packages is presented. CPWto-package adapters (CPA) are fabricated on alumina substrates to mount and measure the high-frequency response of plastic packages. Offset CPA standards in conjunction with an LRM calibration are used to de-embed the response of th...

O IFLA Library Reference Model, LRM, é um modelo conceitual de alto nível que surge da necessidade consolidação dos três modelos Família FR, das demandas do contexto tecnológico vigente e compatibilidade com as melhores práticas Linked Data. LRM trata os dados bibliográficos em sentido amplo, explicitando princípios gerais governam a estrutura lógica informação bibliográfica, atuando como base ...

This paper investigates a unified theory to derive vector network analyzer calibration algorithms based on the T-matrix representation, by which means the line-reflect-match (LRM), line-reflect-match-match (LRMM), and the line-reflect-reflect-match (LRRM) calibrations are formulated. The proposed calibration theory is more general than other versions of LRM, LRMM, and LRRM in that an arbitrary ...

Laryngomalacia (LRM), is the most common laryngeal abnormality of the newborn, caused by a long curled epiglottis, which prolapses posteriorly. Epiglottis prolapse during inspiration (acquired laryngomalacia) is an unusual cause of airway obstruction and a rare cause of obstructive sleep apnea syndrome (OSAS). We present a minimally invasive technique where epiglottis on cadaveric larynx specim...

We present a syntactic theory for the behavioral subset of the Verilog Hardware Description Language. Due to the complexity of the language, the construction of this theory represents a serious test of the suitability of syntactic operational techniques for reasoning about industrial languages. Overall, we have found that these techniques are rather robust but with a few caveats. Our theory for...

Holoparasites are nonphotosynthetic plants that acquire all resources from hosts. The holoparasite Cuscuta gronovii is native to much of the US with a broad host range including Verbesina alternifolia, an understory perennial. Both species grow in moderate to moist soils and occur in habitats that may experience prolonged or episodic drought. We applied the Wise-Abrahamson Limiting Resource Mod...

A series of experiments were conducted in 2003 in the Upper Gila River Valley in Safford, AZ to evaluate several different formulations of the plant growth regulator (PGR) Pix manufactured by BASF. Two experiments were conducted at the Safford Agricultural Center (SAC) while the third was conducted on a grower-cooperator field in the same valley. Experiments conducted at SAC involved evaluating...
