35 patients clinically diagnosed with transient ischemic attack (TIA) and 15 patients clinically diagnosed with reversible ischemic neurological deficits (RIND) were examined by computerized tomography (CT). 34% of TIA patients showed positive CT scans consisting of small hypodenase areas: 60% of RIND patients had larger lesions. In 20% of the overall group(More)
Twelve patients with vascular malformations of the spinal cord have been treated by embolization at the Neuroradiological Department of the Ospedale Maggiore Niguarda Cà Granda from September 1981 to February 1984. Different materials and techniques have been used, including liophylised dura, Ivalon (PVA) and Isobutyl Cianoacrylate. All types of(More)
TO THE EDITOR—Among human immu-nodeficiency virus (HIV)-infected patients on antiretroviral therapy (ART), incomplete viral suppression in cerebro-spinal fluid (CSF) may occur even with undetectable plasma viremia [1–4]. Treatment simplification with " less-drug regimens " may favor adherence and reduce toxicity, but raises concerns on lower central nervous(More)
We engineer a quantum bath that enables entropy and energy exchange with a one-dimensional Bose-Hubbard lattice with attractive on-site interactions. We implement this in an array of three superconducting transmon qubits coupled to a single cavity mode; the transmons represent lattice sites and their excitation quanta embody bosonic particles. Our cooling(More)

We present a general approach to describe slowly driven quantum systems both in real and imaginary time. We highlight many similarities, qualitative and quantitative, between real and imaginary time evolution. We discuss how the metric tensor and the Berry curvature can be extracted from both real and imaginary time simulations as a response of physical(More)
In this work, we examine the neuroradiologic features of the main non vascular clinical conditions responsible for secondary headache; excluding CSF hypotension, which will be treated extensively in another work in this supplement. Headache is not a constant feature of intracranial mass lesions, even of large extension. Headache has a high diagnostic value(More)
Aneurysms of the vertebral artery (VA) are relatively uncommon, accounting for less than 0.5-3.0% of all aneurysms and 20% of aneurysms originating in the posterior fossa. There are three distinct forms of aneurysms: saccular, fusiform and dissecting. The diagnosis of dissecting aneurysm is based on the findings of angiography, surgery and autopsy.(More)
145 children with acute lymphoblastic leukaemia (ALL) were evaluated over a period of 3 years in a multicentre study in which serial cranial computed tomographic (CT) scans of the brain were done. All patients were symptom-free. CT scans were graded as normal, borderline (slight or moderate cerebral atrophy), or pathological (severe cerebral atrophy). 62%(More)
