The mass-accretion rate, Macc, is a crucial parameter for the study of evolution accretion disks around young low-mass stellar objects (YSOs) and planet formation studies. Taurus star forming region (SFR) rich in pre-main sequence (PMS) stars, most them T Tauri class. A variety methodologies have been used past to measure mass samples YSOs Taurus, but despite being general benchmark studies, co...

Abstract Mass accretion from the circumstellar disk onto protostar is a fundamental process during star formation. Measuring mass rate particularly challenging for stars belonging to binary systems, because it often difficult discriminate which component accreting. DQ Tau an almost equal-mass spectroscopic system where components orbit each other every 15.8 days. The known display pulsed accret...

Our High-Dynamic-Range (HDR) world is the result of nonuniform illumination. We like to believe that 21st century technology makes it possible to accurately reproduce any scene. On further study, we find that scene rendition remains a best compromise. Despite all the remarkable accomplishments in digital imaging, we cannot capture and reproduce the light in the world exactly. With still further...

Modulation transfer function (MTF) metrology and interpretation for digital image capture devices has usually concentrated on midto high-frequency information, relative to the half-sampling frequency. These regions typically quantify characteristics and operations such as sharpening, limiting resolution, and aliasing. However, a potential wealth of low-frequency, visually significant informatio...

Deep ‘Analog Artificial Neural Networks’ (ANNs) perform complex classification problems with remarkably high accuracy. However, they rely on humongous amount of power to perform the calculations, veiling the accuracy benefits. The biological brain on the other hand is significantly more powerful than such networks and consumes orders of magnitude less power, indicating us about some conceptual ...

This article explores the ethics of the current "War on Terrorism, asking whether anthropology, the discipline devoted to understanding and dealing with cultural difference, can provide us with critical purchase on the justifications made for American intervention in Afghanistan in terms of liberating, or saving, Afghan women. I look first at the dangers of reifying culture, apparent in the ten...

AIMS To assess the influence of glistenings on the optical quality of acrylic foldable intraocular lens. METHODS Several degrees of glistenings in the optic were experimentally created by immersing the lens in water at 37 degrees C for 48 hours and then at 25 degrees C for 24 hours. Optical bench tests were carried out in water including measurements of spectral transmittance with the spectro...

Nanomaterials modified with biological recognition motifs acquire a myriad of functions that can be exploited for the diagnosis and treatment of cancer. Nevertheless, while bioactive domains can be used to target nanoparticles to cell receptors, shuttle them across cell membranes, and activate cell signaling, such modifications typically include cationic or hydrophobic regions that lead to rapi...

Context. Mass accretion rate determinations are fundamental for an understanding of the evolution of pre-main sequence star circumstellar disks. Aims. Magnetospheric accretion models are used to derive values of the mass accretion rates in objects of very different properties, from brown dwarfs to intermediate-mass stars; we test the validity of these models in the brown dwarf regime, where the...
