Cracking Matrix Encryption Row by Row
Cryptologia, 2007The Hill Cipher, also known as matrix encryption, uses matrices to encipher and decipher text. Various attacks, such as those found by Jack Levine [2, 3, 5], have been published for this system. This article reviews a few previous results and presents a powerful new attack in which the rows of the matrix can be determined independent of one another ...

![Figure][1] Birds do it, bees do it, but unfortunately we cannot. I'm alluding to the capacity for self-powered aerial flight, an activity that we humans can only appreciate from a foreign perspective.

Bacterial chemotaxis systems have cooperatively interacting clusters of transmembrane receptors and signaling proteins to detect, amplify, integrate and adapt to environmental signals. A recent study provides experimental data to construct a new model of the signaling complex.

AbstractDespite the level of supervision of inmates on death row, their suicide rate is higher than both the male prison population in the United States and the population of males over the age of 14 in free society. This study presents suicide data for death row inmates from 1978 through 2010.

Proximal-row carpectomy for diseases of the proximal row
The Journal of Bone & Joint Surgery, 1977Twelve patients were studied following proximal-row carpectomy. Four had a follow-up of twenty years or more. The lesions for which the operation was done included Kienböck's disease, perilunar dislocations, and fractures of the carpal scaphoid. The major complaint of pain was relieved following surgery, and a functional range of motion was obtained ...

The row by row decoupling problem with stability: a structural approach
IEEE Transactions on Automatic Control, 1994The row by row decoupling problem with stability via regular static state feedback is revisited here for linear systems. A new geometric characterization is provided which easily lends to a nice structural solution expressed in terms of infinite and unstable contents. >

It is common to find database applications that use cursors to process one row at a time. Developers tend to think about processing data in a row-by-row fashion. Oracle even uses something called cursors as a high-speed data access mechanism. But cursors in SQL Server are different.

Row Sums and Inverse Row Sums for Nonnegative Matrices
SIAM Journal on Matrix Analysis and Applications, 1994For nonnegative \(n \times n\) matrices, the authors establish conditions under which the row sums of \((I-A)^{-1}\) are increasing if the coordinates of the Perron vector of \(A\) and the row sums of \(A\) are increasing, and give related inequalities.
