What is BICEP 2?

What is BICEP 2?

BICEP2. BICEP2 builds on the small aperture telescope design of BICEP1, but greatly increases the number of detectors to increase mapping speed. The BICEP2 detectors are polarization sensitive bolometers made from a pair of transition edge sensors coupled to orthogonal phased antenna arrays.

Why is CMB polarized?

Polarization describes the orientation of the light perpendicular to the direction of propagation (unpolarized light has no particular orientation) and the CMB is linearly polarized at the 10% level due to Thomson scattering of photons off free electrons in the surface of last scattering.

What are B modes?

B-mode may refer to: B-mode (brightness mode) image, a two-dimensional ultrasound image and the most common type. B-modes, a pattern of polarized light originating from the Big Bang.

What are B modes in the CMB?

A linear polarization field on a surface is expressed in terms of scalar functions, providing an invariant separation into two components; one of these is the B mode, important as a signature of primordial gravitational waves, which would lend support to the inflation hypothesis.

What is B mode polarization?

Polarization describes the way that light-waves are oriented, and B-mode waves are twisted into a swirling pattern. The detection of these swirls was a stunning confirmation of the theory of cosmic inflation.

What is Lexar EZ?

Lexar EZ is a unique combination of the herbicides: S-metolachlor, mesotrione, and atrazine. Lexar EZ controls weeds by interfering with normal germination and seedling development. It is recommended for management of the weed species listed in Tables 1 and 2. Use Restrictions and Precautions. 1.

What is B mode signal?

B-modes rocketed to fame in March 2014 , when a team of scientists working on an experiment called BICEP2 announced the first direct evidence for primordial gravitational waves rippling out from the earliest moments of the universe: a distinctive imprint in the cosmic microwave background (the light left over from the …

What is the B mode in CMB polarization?

What is mesotrione 4SC?

Mesotrione 4SC is a systemic pre-emergence and post-emergence herbicide for selective contact and residual control of broadleaf weeds in corn, sorghum, sugarcane and several other labeled crops.

What is Zidua pro?

BASF’s Zidua® PRO (Premium Residual Option) herbicide is a new broad-spectrum product with powerful burndown and residual control that helps growers address the issue of weed resistance.

What is M mode and B mode?

B-mode: In B-mode ultrasound, a linear array of transducers simultaneously scans a plane through the body that can be viewed as a two-dimensional image on screen. M-mode: M stands for motion.

Is meso 4 the same as tenacity?

This is generic Tenacity. Meso 4 SC Select contains active ingredient Mesotrione 40% exactly the same as Tenacity. It also comes with a convenient filling syringe. Labeled for use on these cool and warm season grass types:Kentucky Bluegrass, Centipedegrass, Buffalograss, Tall Fescue, Perennial Ryegrass, Fine Fescue.

What chemicals are in Zidua?

BASF introduced Zidua PRO (Premium Residual Option) broad-spectrum herbicide for soybean growers. With the active ingredients saflufenacil, imazethapyr and pyroxasulfone, Zidua PRO controls several weeds, including Palmer amaranth and other pigweeds, kochia, lambsquarters, morningglory and waterhemp among others.

What is Sonic herbicide?

Sonic® herbicide provides preemergence control of tough broadleaf weeds to maximize soybean yield potential.

What is M-mode used for?

Background: M-mode or “motion” mode is a form of ultrasound imaging that is of high clinical utility in the emergency department. It can be used in a variety of situations to evaluate motion and timing, and can document tissue movement in a still image when the recording of a video clip is not feasible.
