Under increasing pressure, the Néel temperature of the heavy-fermion compound Ce7Ni3 ~TN51.9 K for P50! decreases and vanishes near Pc'0.33 GPa. Non-Fermi-liquid behavior appears at 0.4 GPa in both the specific heat and ac magnetic susceptibilitiy, Cm /T;2lnT and xac}(12aT ). Above 0.62 GPa, the normal Fermi-liquid state recovers, as indicated by the T independence of CmT and the T 2 dependence...

π = 3.14159 . . . to mean that π is a real number which, accurate to 5 decimal places, equals the above string. To be precise, this means that |π − 3.14159| < 10−5. But this does not tell us what π is. If we want a more accurate approximation, we can calculate one; to 10 decimal places, we have π = 3.1415926536 . . . Continuing, we will develop a sequence of rational approximations to π. One su...

We present a generalised and improved version of the category attack on LSB steganography in JPEG images with straddled embedding path. It detects more reliably low embedding rates and is also less disturbed by double compressed images. The proposed methods are evaluated on several thousand images. The results are compared to both recent blind and specific attacks for JPEG embedding. The propos...

Dr. Carl Rogers, the American psychologist and founder of what has now become known as person-centred counselling or psychotherapy, has always claimed to be grateful that he never had one particular mentor. He has been influenced by many significant figures often holding widely differing viewpoints; but above all he claims to be the student of his own experience and of that of his clients and c...

This paper describes new methods for producing optimal binary signed-digit representations. This can be useful in the fast computation of exponentiations. Contrary to existing algorithms, the digits are scanned from left to right (i.e., from the most significant position to the least significant position). This may lead to better performances in both hardware and software.

The least significant digit first decomposition of integer vectors into words of digit vectors provides a natural way for representing sets of integer vectors by automata. In this paper, the minimal automata representing Presburger sets are proved structurally Presburger: automata obtained by moving the initial state and replacing the accepting condition represent Presburger sets.

Some properties of beamstrahlung are discussed, and plans to observe the effect at SLC by the use of Cherenkov counters are illustrated. Invited talk presented at the International Conference on Advances in Experimental Methods for Colliding Beam Physics, Stanford, California, March 9-13, 1987 * Work supported by the Department of Energy, contract DE A C 0 3 7 6 SF 00 5 15.

abstract: the significance of financial performance of companies makes factors affecting it significant. as a mixed-method research, this paper aimed at investigating the effect of human resources composition in of an organization and the management stability on the financial performance of the organization. first, based on the grounded theory, the indices of human resources composition were id...

abstract This paper describes a novel approach to nd a tighter bound of the transformation of the Min-Max problems into the one of Least-Square Estimation. It is well known that the above transformation of one problem to the other can lead to the proof that their target functions linearly bound each other. However, this linear bound is not a tight one. In this paper, we prove that if we transfo...
