Webster's Revised Unabridged Dictionary
    • n Lac A resinous substance produced mainly on the banyan tree, but to some extent on other trees, by the Laccifer laccaformerly Coccus lacca), a scale-shaped insect, the female of which fixes herself on the bark, and exudes from the margin of her body this resinous substance.Stick-lac is the substance in its natural state, incrusting small twigs. When broken off, and the coloring matter partly removed, the granular residuum is called seed-lac. When melted, and reduced to a thin crust, it is called shell-lac or shellac. Lac is an important ingredient in sealing wax, dyes, varnishes, and lacquers.
    • n Lac One hundred thousand; also, a vaguely great number; as, a lac of rupees.

    • n lac A Middle English form of lack.
    • n lac A resinous incrustation deposited on the twigs of various trees in India and southern Asia by the lac-insect, Carteria lacca. The substance is formed by the mature female, from which it exudes, inclosing the eggs and keeping them attached to the branch. At the proper time the twigs are broken off by the native collectors, and exposed to the sun to kill the insect and to dry the lac. These twigs, with the attached resin, inclosed insects, and ova, constitute the stick-lac. Lac is a dark-red transparent resin, with a crystalline fracture, and bitter in taste. It yields only a part of its coloring matter to water, but borax solution exercises a special solvent power upon it. It is still much used in the East for dyeing woolen goods and leather, producing scarlet shades, not so brilliant as cochiueal, but somewhat faster. Seed-lac is obtained from stick-lac by removing the resinous concretions from the twigs and triturating with water. The greater part of the coloring matter is dissolved, and the granular portion which remains after drying is the seed-lac. Shelllac or shellac is obtained by melting the seed-lac in cotton-cloth bags, straining, and allowing it to drop on to sticks or leaves. In this way the resin spreads into thin plates, in which state it is found in commerce. It is used in the manufacture of spirit-varnishes and sealing-wax, and as a stiffening for hats. Button-lac differs from shellac only in form. In its melted state it is dropped into disk forms three inches in diameter and one sixth of an inch thick. Lac-dye is imported from India, and is probably prepared by extracting the coloring matter from stick-lac with a weak alkali to which alumina has been added. It is used like cochineal for dyeing scarlet on woolens, but has only half as much tinctorial strength. Lac-lake is obtained by treating stick-lac with caustic soda and alum. It has a limited use as an artists' color, producing results similar to cochineal carmines, though less brilliant. The extraction of the color from the resin leaves the shellac of commerce. The general term lac is extended to the similar secretion of any lac-insect.
    • n lac The sum of 100,000, usually of rupees. The usual pointing for sums of Indian money rising above a lac is with a comma after the number of lacs: thus, Rs. 30,52,000 (i. e. thirty lacs and fifty-two thousand) or Rs. 49,98,810, instead of the equivalent 3,052,000 and 4,998,810 rupees.

In science:

Note that further “refining” of this set of cuts would not change the results as the sets of BL Lacs obtained would overlap almost completely.
Cuts and penalties: comment on "The clustering of ultra-high energy cosmic rays and their sources"
We stress again that the absence of correlations of cosmic rays with the entire sample of known BL Lacs does not mean anything.
Cuts and penalties: comment on "The clustering of ultra-high energy cosmic rays and their sources"
Physically, cosmic rays correlate with the brightest BL Lacs.
Cuts and penalties: comment on "The clustering of ultra-high energy cosmic rays and their sources"
The authors of Ref. have chosen GRBs as a control set where correlations are not expected; it has to be compared with the case of BL Lacs.
Cuts and penalties: comment on "The clustering of ultra-high energy cosmic rays and their sources"
Like in the case of BL Lacs, we then calculate the probability of the observed excess of UHECRs around GRBs as a function of the cut.
Cuts and penalties: comment on "The clustering of ultra-high energy cosmic rays and their sources"
To mimic the case of BL Lacs we perform a similar test with two independent cuts.
Cuts and penalties: comment on "The clustering of ultra-high energy cosmic rays and their sources"
The correlations found in Ref. for a particular set of UHECR and BL Lacs suggest, strictly speaking, only that UHECR and BL Lacs are connected to each other.
Cuts and penalties: comment on "The clustering of ultra-high energy cosmic rays and their sources"
Here is a sketch of these attempts, each bringing additional evidence of the connection between UHECR and BL Lacs.
Cuts and penalties: comment on "The clustering of ultra-high energy cosmic rays and their sources"
The idea was that such a reconstruction should improve correlations of UHECR with BL Lacs if the latter are the sources.
Cuts and penalties: comment on "The clustering of ultra-high energy cosmic rays and their sources"
In the case at hand the “null hypothesis” which is being tested is that BL Lacs (and, in particular, any subset of them) and UHECR are uncorrelated.
Cuts and penalties: comment on "The clustering of ultra-high energy cosmic rays and their sources"
Having found such counter-example (i.e. the case when correlation is significant), the only thing which can be concluded, to a certain confidence level, is that UHECR and a particular subset of BL Lacs are correlated.
Cuts and penalties: comment on "The clustering of ultra-high energy cosmic rays and their sources"
We model the overall emission in the frame of a synchrotron self-Compton scenario, which well describes the SED of BL Lacs.
The nuclear SED of NGC6251: a BL Lac in the center of an FR I radio galaxy
The model parameters we obtain confirm also quantitatively the FR I–BL Lac unification model and imply a rather small viewing angle to this source (θ < ∼ 20◦).
The nuclear SED of NGC6251: a BL Lac in the center of an FR I radio galaxy
Our result is that the nucleus of this low-power radio galaxy can also be interpreted as a misoriented BL Lac.
The nuclear SED of NGC6251: a BL Lac in the center of an FR I radio galaxy
The model is particularly appropriate for low-power ob jects (BL Lacs), in which the external radiation field is probably low, and the dominant source of seed photons for inverse-Compton scattering is the synchrotron radiation field itself.
