in the present paper we give a partially negative answer to a conjecture of ghahramani, runde and willis. we also discuss the derivation problem for both foundation semigroup algebras and clifford semigroup algebras. in particular, we prove that if s is a topological clifford semigroup for which es is finite, then h1(m(s),m(s))={0}.

Post-Occupancy Evaluation (POE) has become increasingly accepted and influential among client organizations responsible for large building management and construction programs. Managers and administrators look to POE to provide answers to· important facilities questions. This increased focus on decision-making has resulted in a number of changes to the way in which POEs are conducted, including...

Correct authenticated decryption requires the receiver to buffer the decrypted message until the authenticity check has been performed. In high-speed networks, which must handle large message frames at low latency, this behavior becomes practically infeasible. This paper proposes CCA-secure on-line ciphers as a practical alternative to AE schemes since the former provide some defense against ma...

The retention behavior on poly(oxyethylene) (POE) chemically-bonded stationary phases was investigated in ion-exchange, reversed-phase (RP) and hydrophilic interaction (HILIC) modes in capillary liquid chromatography. The eluent cations fixed on the oxygen atoms of the POE chains by ion-dipole interaction worked as the anion-exchange sites for the separation of inorganic anions. Nonpolar analyt...

The present article reviews the use of polyethylene glycol (PEG) or polyoxyethylene (POE) as the stationary phase for the separation of inorganic anions in ion chromatography and discusses about the retention mechanisms involved in the separation of anions on the novel stationary phases. PEG permanently coated on a hydrophobic stationary phase retained anions in the partition mode and allowed ...

A Product of Experts (PoE) model is a probabilistic model which combines a number of individual component models by multiplying their probabilities. A typical PoE model is an exponential family Harmonious introduced by Welling et al. In this paper, we apply a hierarchical PoE model, Complex-Cell Model (CCM), to image retrival and compare the performance with a kind of standard harmonious model,...

The authors retrospectively explored cortical differences between 26 patients with temporal lobe epilepsy and psychosis of epilepsy (POE), 24 patients with temporal lobe epilepsy (TLE) alone, and 20 healthy comparison subjects. Using voxel-based morphometry based on statistical parametric mapping (SPM99), which is an unbiased and fully automated technique to test for morphometric differences, m...

Background: Medication dosing errors may have grave consequences for neonatal patients. Computerized Physician Order Entry (CPOE) with dosing decision support functionalities has been effective in reducing these errors. However, the adoption rate is low. Physicians' resistance has been identified as a significant barrier. To reduce this resistance, the system should be designed in close collabo...

in this paper we study the existence of commuting regular elements, verifying the notion left (right) commuting regular elements and its properties in the groupoid g(n) . also we show that g(n) contains commuting regular subsemigroup and give a necessary and sucient condition for the groupoid g(n) to be commuting regular.
