I spent only 2 hours with Oliver Sacks, in February 2011. It was his home on Horatio Street the West Village of New York City. had written to him, as a Columbia colleague, about sleep disturbance that gaining hegemony my life. My nocturnal dream world, 3 years running, become other worldly, uncannily alive and exhausting; “case” defied accomplished academic neurologists well three studies overn...

While analyzing CAIDA Internet traces of TCP traffic to detect instances of data reneging, we frequently observed four misbehaviors in the generation of SACKs. These misbehaviors could result in the data sender mistakenly thinking data reneging occurred. Further testing detected two additional SACK generation misbehaviors which in the worst case could result in a data sender receiving a SACK fo...

Most known by his literary ability, the words of the neurologist Oliver Sacks (1933-2015) also had an impact on scientific community about the role of levodopa on parkinsonisms. Different from the most authors and based on his experience described on the book "Awakenings", he had a pessimistic opinion about levodopa, which was related on many articles written by himself and colleagues in early ...

The patient is a 34-year-old female with systemic lupus erythematosus and secondary antiphospholipid antibody syndrome, who evolved with convulsive crises, partially controlled with an anticonvulsant, and auscultation of a cardiac murmur, whose investigation showed the presence of a mitral valve vegetation. Once the diagnosis of Libman-Sacks endocarditis was established, therapy with warfarin s...

In antiphospholipid syndrome (APS), there is a high prevalence of valvular heart disease which leads to increased risk of thrombo-embolic events, in particular, cerebrovascular events. We present a patient with cerebral infarction, previous deep-vein thrombosis, and miscarriages with positive lupus anticoagulant and anticardiolipin antibodies. Echocardiographic examination revealed mitral valve...

We study linear estimators for the weighted integral of a stochastic process. The process may only be observed on a nite sampling design. The error is deened in mean square sense, and the process is assumed to satisfy Sacks-Ylvisaker regularity conditions of order r 2 N 0. We show that sampling at the quantiles of a particular density already yields asymptotically optimal estimators. Hereby we ...

It is shown that for any computably enumerable degree a 6= 0, any degree c 6= 0, and any Turing degree s, if s ≥ 0, and c.e. in a, then there exists a c.e. degree x with the following properties, (1) x < a, c 6≤ x, (2) a is splittable over x, and (3) x = s. This implies that the Sacks’ splitting theorem and the Sacks’ jump theorem can be uniformly combined. A corollary is that there is no atomi...

In this article we prove a Sacks-Uhlenbeck/Struwe type global regularity result for wave-maps Φ : R → M into general compact target manifolds M.
