| A biologically motivated mechanism for self-organizing a neural network with modi able lateral connections is presented. The weight modi cation rules are purely activity-dependent, unsupervised and local. The lateral interaction weights are initially random but develop into a \Mexican hat" shape around each neuron. At the same time, the external inputweights self-organize to form a topologica...

. This paper discusses black-hat and hat-nonterm, two tools for locating and diagnosing non-termination errors in Haskell programs. Both of these tools give a small trace which is intended to illuminate the cause of the non-termination error. black-hat analyses programs which contain black holes, a particularly restricted kind of non-termination error, while hatnonterm applies the approach used...

The topic is the hat problem in which each of n players is randomly fitted with a blue or red hat. Then everybody can try to guess simultaneously his own hat color by looking at the hat colors of the other players. The team wins if at least one player guesses his hat color correctly, and no one guesses his hat color wrong; otherwise the team loses. The aim is to maximize the probability of winn...

Analysis of the laminated composite plates under transverse loading is considered using the new method of Isogeometric Analysis (IGA). Non-Uniform Rational B-Splines(NURBS)are used as shape functions for modeling the geometry of the structure and also are used as shape functions in the analysis process. To show robustness of the new technique, some examples are represented and are compared with...

The Hohenberg–Kohn (HK) theorem for interacting electrons is a cornerstone of modern electronic structure calculations. For general quantum system, HK-type Hamiltonian in the form H ̂ hk { g i } = int + ∑ O $\hat {H}_{\rm hk}\lbrace g_i\rbrace =\hat int}+\sum_i g_i \hat O_i$ can always be defined, by grouping those terms with fixed or preknown coefficients into an internal part int}$ , and facto...

The human airway trypsin-like protease (HAT) is a respiratory epithelium-associated, type II transmembrane serine protease, which is also detected as an extracellular enzyme in lung fluids during airway inflammatory disorders. We have evaluated its capacity to affect the urokinase-type plasminogen activator receptor (uPAR), a membrane glycolipid-anchored, three-domain (D1D2D3) glycoprotein that...

In this memo, we review the three basic schemes of obtaining low spatial frequency data for millimeter array observations: (1) use of a large single dish, (2) interferometry with a multi-size array, and (3) scanning with a homogeneous array. We describe an application of the homogeneous array concept using the three antenna Hat Creek array. In an appendix, we analyze the eeects of random, uncor...

Multiple structural, biochemical and in vivo studies have solidified the role that histone acetyltransferases (HATs) play in regulation of the p53 pathway. 1 HATs are known to modulate p53 functions in many ways, from regulating its stability to promoting acetyla-tion-dependent interactions with DnA as well as various co-factors and chromatin modi-fiers. 1 Of these, p300, CBP, PCAF and Tip60 ar...

The shape of the beam profile of a discharge excited XeCl excimer laser using a spiker-sustainer electrical circuit has been varied from a ‘bell’-, through a ‘top-hat’-, to a ‘camel-back’-profile by varying the delay between the spiker pulse and the maincurrent with the circuit operating in the charge-mode. Fine-tuning of the beam profile can be done by varying the charging voltage of the main ...
