First Detection of Near-Infrared Intraday Variations in the Seyfert 1 Nucleus NGC4395 [PDF]

Astrophys.J. 643 (2006) L5-L8, 2006
We carried out a one-night optical V and near-infrared JHK monitoring observation of the least luminous Seyfert 1 galaxy, NGC4395, on 2004 May 1, and detected for the first time the intraday flux variations in the J and H bands, while such variation was not clearly seen for the K band.

Causality Implies Inflationary Back-Reaction

, 2017
There is a widespread belief among inflationary cosmologists that a local observer cannot sense super-horizon gravitons. The argument goes that a local observer would subsume super-horizon gravitons into a redefinition of his coordinate system.

Diagnostic challenges in the assessment of thyroid neoplasms using nuclear features and vascular and capsular invasion: a multi-center interobserver agreement study [PDF]

Journal of Pathology and Translational Medicine
Background The diagnosis of thyroid neoplasms necessitates the identification of distinct histological features. Various education/hospital centers located in cities across Indonesia likely result in discordances among pathologists when diagnosing ...

Energy Dependent Intensity Variation of the Persistent X-ray Emission of Magnetars Observed with Suzaku [PDF]

, 2018
Emission mechanism of the magnetars is still controversial while various observational and theoretical studies have been made. In order to investigate mechanisms of both the persistent X-ray emission and the burst emission of the magnetars, we have proposed a model that the persistent X-ray emission consists of numerous micro-bursts of various sizes ...

Longitudinal Intergroup Contact Effects on Prejudice Using Self- and Observer-Reports [PDF]

, 2012
Longitudinal effects of intergroup contact on prejudice were investigated in a sample of 65 young adults (Sample 1) and a sample of their close friends (Sample 2, N = 172), adopting a full cross-lagged panel design.

Reproducibility and repeatability of measuring the electrical impedance of the pregnant human cervix-the effect of probe size and applied pressure [PDF]

, 2009
Background: The utility of cervical electrical impedance spectroscopy (EIS) as a diagnostic tool is being investigated in clinical trials. We sought to assess the reliability of two different sizes of tetrapolar probes used in measuring cervical ...

Effects of chronic browsing on life‐history traits of an irruptive large herbivore population

Population Ecology, EarlyView.
This study aimed to determine the relationship between diet quality, body mass, and size (hind foot length), and female reproduction and sought to identify the mechanism by which high density under severe food limitations is maintained. Our results demonstrated that sika deer introduced to Nakanoshima Island have maintained high densities through high ...

Inter-observer and intra-observer agreement in drug-induced sedation endoscopy — a systematic approach

The Egyptian Journal of Otolaryngology, 2022
Objective To evaluate the feasibility of systematic observer training in drug-induced sedation endoscopy (DISE) interpretation. Methods Fifty DISE videos were randomly selected from a group of 200 videos of cohort of patients with OSA and/or snoring. The

Dynamic urban projection mapping [PDF]

, 2017
“Dynamic projection mapping” is a variation of the best-known “projection mapping”. It considers the perceptual analysis of the urban landscape in which the video projection and the observer’s displacement speed are hypothesized.
