We present a new approach to the problem of estimating the redshift of galaxies from photometric data. The approach uses a genetic algorithm combined with non-linear regression to model the 2SLAQ LRG data set with SDSS DR7 photometry. The genetic alg...

We modify the recent analytic formula given by Allen and Casper for the rate at which piecewise linear cosmic string loops lose energy to gravitational radiation to yield the analogous analytic formula for the rate at which loops radiate momentum....
Photo captions, also known as cutlines, are a few lines of text used to explain and elaborate on published photographs. In some cases captions and cutlines
Nov 18, 2025 · When Regent Seven Seas Cruises ' newest ship, Seven Seas Prestige, sets sail in December 2026, it will be the first ship in the line's Prestige class.
Feb 24, 2008 · Sydney once again has turned on the weather for a massive turn out of people and events. Two of the worlds great ocean liners will pass each other in the harbour tonight at 6.30pm …
We present a new combinatorial characterization for local optimality of a codeword in an irregular Tanner code. The main novelty in this characterization is that it is based on a linear combination of subtrees in the computation trees. These subtrees...

Nov 10, 2025 · A clade is a group of organisms that forms a single, complete branch on a phylogenetic tree. It is formally known as a monophyletic group, derived from Greek meaning “one lineage.”
A clade is a grouping that includes a common ancestor and all the descendants (living and extinct) of that ancestor. Using a phylogeny, it is easy to tell if a group of lineages forms a clade.
We’re closing in on free agency. As I’m writing this, the deadline for the franchise tag has passed only hours ago, and teams are beginning to escalate their transactions as they position themselv...

Nov 6, 2025 · The urethra is the vessel responsible for transporting urine from the bladder to an external opening in the perineum. It is lined by stratified columnar epithelium, which is protected from the …
A cantilever beam under axial flow, confined or not, is known to develop self-sustained oscillations at sufficiently large flow velocities. In recent decades, the analysis of this archetypal system has been mostly pursued under linearized conditions,...
We'll tell you the driving distance in miles and also the 'flight mileage', the distance between the cities as if you could take a direct flight between them, also called straight line or as the crow flies distance.
A nano-second scale in situ probe reveals that a bulk linear polymer undergoes a sharp phase transition as a function of the degree of conversion, as it nears the glass transition. The scaling behaviour is in the same universality class as percolat...
Feb 5, 2015 · Tensor : Multidimensional array :: Linear transformation : Matrix. The short of it is, tensors and multidimensional arrays are different types of object; the first is a type of function, the second is a …
Every tensor is associated with a linear map that produces a scalar. For instance, a vector can be identified with a map that takes in another vector (in the presence of an inner product) and produces …
