Polly H. Carder Collection on George F. Root
No full textGeorge Frederick Root (1820-1895) was an American songwriter and music educator. He is perhaps best known for his song "The Battle Cry of Freedom," which was written and rose to popularity during the U.S. Civil War. The Polly H. Carder Collection on George F. Root contains original published scores and songbooks from the period 1852-1907 and photocopied scores collected by Polly H. Carder, author of the book George F. Root, Civil War Songwriter: A Biography. The collection also contains a short article, "The Last Days of George F. Root," written by Root's daughter, Clara Louise Burnham

Automatic classification of mammographic masses by ROI cross sectional intensity profile analysis
No full textBreast cancer represents the leading cause of fatality among cancers for women and there is still no known way of preventing this pathology. Computer aided analysis systems could be very helpful to improve both the sensitivity and the specificity. In this paper, a computer aided diagnosis system for malignant/benign masses classification of ROI in mammograms based on wavelet transform decomposition and artificial neural network (ANN) classifier is shown. The main novelty of the system is to consider only small 1D signals crossing the abnormal region, allowing to drastically reduce the amount of data to be processed. An experimental analysis performed on a set of images from DDSM database has shown the effectiveness of the proposed method
Epidemiologie.
No full textDie Adipositas lässt sich epidemiologisch gut erheben, da zur Erfassung nur einfache Methoden angewendet werden müssen. Verlässlich sind allerdings nur Untersuchungen, in denen die Probanden auch wirklich gemessen und gewogen wurden; Selbstangaben von Patienten aufgrund von Befragungen sind weniger verlässlich. In den letzten Jahrzehnten hat die Adipositas in Industrienationen zu einer pandemischen Verbreitung geführt. Aufgrund der assoziierten Morbidität und Einschränkung der Lebensqualität hat die Adipositas auch eine erhebliche ökonomische Bedeutung, was für die Gesundheitspolitik und Kostenträger von Sozialleistungen von Interesse ist. Epidemiologische Daten tragen auch zu ätiologischen Erkenntnissen der Adipositas bei
Electron and positron scattering from 1,1-C₂H₂F₂
No full text1,1-difluoroethylene (1,1-C₂H₂F₂) molecules have been studied for the first time experimentally and theoretically by electron and positron impact. 0.4-1000 eV electron and 0.2-1000 eV positron impact total cross sections (TCSs) were measured using a retarding potential time-of-flight apparatus. In order to probe the resonances observed in the electron TCSs, a crossed-beam method was used to investigate vibrational excitation cross sections over the energy range of 1.3-49 eV and scattering angles 90 degrees and 120 degrees for the two loss energies 0.115 and 0.381 eV corresponding to the dominant C-H (ν₂ and ν₉) stretching and the combined C-F (ν₃) stretching and CH₂ (ν₁₁) rocking vibrations, respectively. Electron impact elastic integral cross sections are also reported for calculations carried out using the Schwinger multichannel method with pseudopotentials for the energy range from 0.5 to 50 eV in the static-exchange approximation and from 0.5 to 20 eV in the static-exchange plus polarization approximation. Resonance peaks observed centered at about 2.3, 6.5, and 16 eV in the TCSs have been shown to be mainly due to the vibrational and elastic channels, and assigned to the B₂, B₁, and A₁ symmetries, respectively. The pi* resonance peak at 1.8 eV in C₂H₄ is observed shifted to 2.3 eV in 1,1-C₂H₂F₂ and to 2.5 eV in C₂F₄; a phenomenon attributed to the decreasing C=C bond length from C₂H₄ to C₂F₄. For positron impact a conspicuous peak is observed below the positronium formation threshold at about 1 eV, and other less pronounced ones centered at about 5 and 20 eV.The work was supported in part by a Grant-in-Aid, the
