Signatures of Ultralight Bosons in the Orbital Eccentricity of Binary Black Holes.

We show that the existence of clouds of ultralight particles surrounding black holes during their cosmological history as members of a binary system can leave a measurable imprint on the distribution of masses and orbital eccentricities observable with future gravitational-wave detectors. Notably, we find that for nonprecessing binaries with chirp masses M≲10M_{⊙}, formed exclusively in isolation, larger-than-expected values of the eccentricity, i.e.

Differences in oligoclonal bands and visual evoked potentials in patients with radiologically and clinically isolated syndrome.

The aim of this study was to determine the prevalence of cerebrospinal fluid (CSF) and visual evoked potentials (VEP) abnormalities, and ANA titers in patients with either clinically or radiologically isolated syndrome (CIS and RIS). We gathered records from 330 hospitalized patients diagnosed with CIS/RIS within a 3-year period. Symptoms, CSF findings, VEP and ANA titers were analyzed.

Do we need broad immunological work-up in all patients with CIS?

Background: The aim of this study was to determine the prevalence of altered immunological tests and their clinical significance in patients with clinically isolated syndrome (CIS) suggestive of multiple sclerosis (MS).

Patients And Methods: The information was gathered from medical records of patients hospitalized in the Referral Center for Demyelinating Diseases in the 2008-2010 period. All patients had ANA, ENA profile, ANCA, aCl IgG and IgM, C3, C4, CH50, anti-TPO, AST and RF antibodies tested.
