A method is suggested to reduce structural response to earthquakes using viscous dampers with their effect magnified by mechanical levers (lever arms). The lever arms are used to magnify the drift and the drift velocities transferred from the structure to the dampers thus producing in larger energy dissipation. An optimal design procedure based on the LQR technique is proposed in this study to ...
Germ line PTPN11 mutations cause 50% of cases of Noonan syndrome (NS). Somatic mutations in PTPN11 occur in 35% of patients with de novo, nonsyndromic juvenile myelomonocytic leukemia (JMML). Myeloproliferative disorders (MPDs), either transient or more fulminant forms, can also occur in infants with NS (NS/MPD). We identified PTPN11 mutations in blood or bone marrow specimens from 77 newly rep...
DEARSIRS In the Psychiatric Bulletin (September 1989,13, 513), Dr Lai Fernando discussed his dearth of multiple personality disorder (MPD) patients in various countries including Canada. He also knew of no other colleagues with such cases. However, many of his Canadian colleagues are treating MPD patients as well as doing research. My own initial cases date from 1977 when I was working in Germa...
The history and dynamics of the martian polar deposits (MPD), the largest known water reservoirs on Mars, are of great interest, but estimates of ice grain size are required before detailed modeling can be performed. We clarify the microphysical processes that may control grain size in the MPD. If the MPD are ∼2% dust by mass, the maximum ice grain size is ∼1 mm due to grain boundary pinning by...
BACKGROUND The rapid development of programmed death 1 (PD-1)/programmed death ligand 1 (PD-L1) inhibitors has generated an urgent need for biomarkers assisting the selection of patients eligible for therapy. The use of PD-L1 immunohistochemistry, which has been suggested as a predictive biomarker, however, is confounded by multiple unresolved issues. The aim of this study therefore was to quan...
We previously demonstrated reduced levels of low density lipoprotein (LDL) cholesterol in association with increased total fractional catabolic rates (FCR( of LDL apoprotein B (apo B) in individuals with myeloproliferative diseases (MPD). The removal of LDL from plasma and interstitial fluid is mediated via receptor and nonreceptor pathways. We attempted to quantitate LDL catabolism via each of...
OBJECTIVE To compare the multidetector CT (MDCT) features of malignant pleural mesothelioma (MPM) and metastatic pleural disease (MPD). MATERIALS AND METHODS The authors reviewed the MDCT images of 167 patients, 103 patients with MPM and 64 patients with MPD. All 167 cases were pathologically confirmed by sonography-guided needle biopsy of pleura, thoracoscopic pleural biopsy, or open thoraco...
additional dampers are employed in order to decrease the dynamic response of structure against the earthquake and wind loading recently. in this study, two types of systems related to waste of inactive energy, i.e. frictional damper which is categorized in dampers dependent on movement and viscoelastic damper which is categorized in dampers dependent on velocity, in making steel structures resi...
