Polarization and Spectral Energy Distribution in OJ 287 during the 2016/17 Outbursts

Galaxies, 2017
We report optical photometric and polarimetric observations of the blazar OJ 287 gathered during 2016/17. The high level of activity, noticed after the General Relativity Centenary flare, is argued to be part of the follow-up flares that exhibited high ...

The effect of ovarian stimulation protocol on follicular asynchrony during in vitro fertilization – A retrospective cohort study

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective To examine the effect of controlled ovarian stimulation (COS) protocol on follicular synchrony in a subsequent in vitro fertilization (IVF) cycle in patients whose previous cycle was canceled due to asynchrony. Methods A single‐center retrospective‐cohort study (January 2018–March 2024), including women undergoing IVF who had: (1) a ...

Human biomarker navigator

iMeta, EarlyView.
The Human Biomarker Navigator integrates the disease continuum, biomarker dynamics, cross‐organ biomarker networks, biomarker classification, and technology‐driven paradigms. It maps how biomarkers link multi‐system physiology and pathology across the nervous, respiratory, endocrine, circulatory, immune, digestive, urinary, reproductive, and ...

S5 1803+78 Revisited

Acta Polytechnica, 2012
We report on our optical monitoring of the BL Lac object S5 1803+78 from 1996 to 2011. The source showed no clear periodicity, but a time scale of about 1 300 days between major flares is possibly present. No systematic trend of the color index with flux

Particle acceleration in the presence of weak turbulence at an X-type neutral point [PDF]

, 2012
We simulate the likely noisy situation near a reconnection region by superposing many 2D linear reconnection eigenmodes. The superposition of modes on the steady state X-type magnetic field creates multiple X- and O-type neutral points close to the ...

From ACR O‐RADS 2022 to Explainable Deep Learning

Journal of Ultrasound in Medicine, EarlyView.
Objectives The 2022 update of the Ovarian‐Adnexal Reporting and Data System (O‐RADS) improves risk stratification of adnexal lesions; however, radiologist interpretation remains subject to inter‐observer variability and conservative diagnostic thresholds.

Rising Near-ultraviolet Spectra in Stellar Megaflares

The Astrophysical Journal
Flares from M dwarf stars can attain energies up to 10 ^4 times larger than solar flares but are generally thought to result from similar processes of magnetic energy release and particle acceleration.

Frequency stability of a self-phase-locked degenerate continuous-wave optical parametric oscillator [PDF]

, 2003
The properties of a self-phase-locked by-2-divider optical parametric oscillator are presented. A locking range of up to 156 MHz is measured, and the divider's relative frequency stability is shown to be better than 6/spl times/10/sup -14/

Optical cements for interferometric applications [PDF]

, 1984
The wave front distortion introduced by optical cements is important in interferometric applications. We describe here tests performed to characterize two common cements, Epo-Tek 301 and Norland Optical Adhesive ...
