Buffer-gas-free mass-selective ion centering in Penning traps by simultaneous dipolar excitation of magnetron motion and quadrupolar excitation for i…
2012
A new excitation scheme of the radial ion-motional modes is introduced for Penning-trap ion-cyclotron-resonance experiments. By simultaneous dipolar excitation of the magnetron motion and resonant quadrupolar excitation for the conversion between magnetron motion and cyclotron motion, a mass-selective recentering of the ions of interest is performed while all other (contaminant) ions are ejected from the trap. This new technique does not rely on the application of a buffer gas as presently used [G. Savard, St. Becker, G. Bollen, H.-J. Kluge, R.B. Moore, Th. Otto, L Schweikhard, H. Stolzenberg, U. Wiess, Physics Letters A 158 (1991) 247] and will thus prevent charge-exchange reactions and da…
Functional anatomy of motor recovery after early brain damage
2004
Functional magnetic resonance imaging and transcranial magnetic stimulation were used to examine a 34 year-old right-handed patient, who, at the age of 6 years, had experienced sudden right hemiplegia, seizures, and stupor during a bout of measles encephalitis, followed by incomplete distal right motor recovery. Morphological MRI showed massive unilateral enlargement of the left ventricle, associated with extreme thinning of the white and gray matter, with partial preservation of the pyramidal tract. Functional MRI and transcranial magnetic stimulation revealed reorganization of the motor cortices, and integrity of the corticospinal pathway, respectively. Our findings indicate that complete…
A questionable diagnosis in a woman with drowsiness
2019
A 60-year-old caucasian woman was admitted to our Division of Internal Medicine for a 10-day history of drowsiness, irritability, dysphasia, weakness and difficulties in the maintenance of an upright position with numerous falls, with a traumatic lumbar spine injury and on the left shoulder. Then, while general clinical conditions were getting worse with drowsiness and hyposthenia of the right side of the body, after neurological evaluation, she was recovered in hospital. Pathological history includes a 20-year epilepsy and depression with emotional lability, behavior’s disorders and attempted suicide. For such reason, she was followed in a mental health institute, treated with phenobarbita…
Factors Associated with Mortality in Patients Experiencing First Episodes of Acquired Thrombotic Thrombocytopenic Purpura (aTTP). Results of the Span…
2019
Introduction: Acquired thrombotic thrombocytopenic purpura (aTTP) is a rare, but life-threatening, hematological disorder characterized by severe thrombocytopenia, hemolytic microangiopathic anemia, and frequent organ damage. The underlying pathophysiology of aTTP is a functional deficiency of plasma ADAMTS13 activity caused by antibodies directed against the ADAMTS13 protease. Despite plasma exchange (PEX) and immunosuppression with corticosteroids, and, more recently, rituximab, which achieve remission in most patients with aTTP, 10-20% of patients are refractory to treatment and die as a result of disease progression. Most of such deaths occur during first episodes of aTTP, as subsequent…

Der Pulmonalarteriendruck des Menschen bei Kreislaufver�nderungen im Phenothiazin-Schlaf
1957
An 11 kreislaufgesunden normotonen Versuchspersonen wurden der Brachial- und Lungenarteriendruck synchron im Wachzustand und im Phenothiazin-Schlaf unter dem Einflus von Adrenalin, Effortil, Vasculat, Noradrenalin, Hypophysin, Acetylcholin, Histamin, Orthostase, Bulbusdruck und Carotissinusentlastung untersucht. Im Gegensatz zu erheblichen Druckveranderungen in der Brachialarterie konnten bei samtlichen Untersuchungen keine vergleichbaren Veranderungen des Pulmonalarteriendruckes gefunden werden.
Evidence of octupole-phonons at high spin in 207Pb
2019
A lifetime measurement of the 19/2 state in Pb has been performed using the Recoil Distance Doppler-Shift (RDDS) method. The nuclei of interest were produced in multi-nucleon transfer reactions induced by a Pb beam impinging on a Mo enriched target. The beam-like nuclei were detected and identified in terms of their atomic mass number in the VAMOS++ spectrometer while the prompt γ rays were detected by the AGATA tracking array. The measured large reduced transition probability B(E3,19/2→13/2)=40(8) W.u. is the first indication of the octupole phonon at high spin in Pb. An analysis in terms of a particle-octupole-vibration coupling model indicates that the measured B(E3) value in Pb is compa…
Precision measurement of the magnetic octupole moment in 45Sc as a test for state-of-the-art atomic- and nuclear-structure theory
2020
We report on measurements of the hyperfine $A, B$ and $C$-constants of the $3d4s^2 ~^2D_{5/2}$ and $3d4s^2 ~^2D_{3/2}$ atomic states in $^{45}$Sc. High-precision atomic calculations of the hyperfine fields of these states and second-order corrections are performed, and are used to extract $C_{5/2}=-0.06(6)$ kHz and $C_{3/2}=+0.04(3)$ kHz from the data. These results are one order of magnitude more precise than the available literature. From the combined analysis of both atomic states, we infer the nuclear magnetic octupole moment $\Omega = -0.07(53) \mu_N b$, including experimental and atomic structure-related uncertainties. With a single valence proton outside of a magic calcium core, scan…
Possedere intimamente
2016
Questo scritto riflette sui luoghi dell’Edificio 14 del Campus dell’Università degli Studi di Palermo, opera di Pasquale Culotta, Giuseppe Laudicina, Bibi Leone, Tilde Marra, costruito come sede della facoltà di architettura. Alcuni docenti, nel corso degli anni più recenti, hanno scelto questo edificio come oggetto di attenzioni ed esercitazioni della loro didattica. Gli studenti, in questo modo, hanno potuto sperimentarlo come strumento di conoscenza da guardare con rinnovato stupore, alla scoperta delle forme e delle relazioni della sua architettura. Esso si è reso loro disponibile alla comprensione delle forme nello spazio, e anche a provocare stupore come virtù sua intrinseca, che coab…
