The Rosenzweig-Porter random matrix ensemble serves as a qualitative phenomenological model for the level statistics and fractality of eigenstates across many-body localization transition in static systems. We propose unitary (circular) analogue this ensemble, which similarly captures phenomenology periodically driven (Floquet) define outcome Dyson Brownian motion process. show numerical eviden...

We use noncommutative differential forms (which were first introduced by Connes) to construct a noncommutative version of the complex of Cenkl and Porter Ω∗,∗(X) for a simplicial set X. The algebra Ω∗,∗(X) is a differential graded algebra with a filtration Ω∗,q(X) ⊂ Ω∗,q+1(X), such that Ω∗,q(X) is a Qq-module, where Q0 = Q1 = Z and Qq = Z[1/2, . . . ,1/q] for q > 1. Then we use noncommutative v...

Squamous cell carcinoma is the most common intraoral malignancy (Scully & Porter, 2000), and mainly affects male patients with ages varying between 40-80 years (Regezi et al., 1999; Scully & Porter and Neville & Day, 2002), although recent studies (Regezi et al.) have reported the occurrence of this malignancy in younger patients. Tobacco and betel use, alcohol consumption, viruses, and other o...

Erythromycin, phenazopyridine, methenamine mandelate, acetazolamide, and ascorbic acid reportedly interfere with the Porter-Silber reaction in the determination of urinary 17-hydroxycorticosteroids. Sodium bisulfite, added to the urine after hydrolysis with glucuronidase, removed almost all nonsteroidal interferences in urine from healthy adults medicated with the first three drugs, but such st...

Almost four decades ago, Porter (Porter, 1970) and Edelman (Edelman, 1970) established the structure of antibodies (immunoglobulins). This discovery dramatically improved the understanding that antibodies function as both receptor and effector molecules. Humoral or antibody-mediated immunity requires noncovalent contact between antigens (ligands) and antibodies (receptors). Hypervariable region...

SUMMARY Protein secondary structure and solvent accessibility predictions are a fundamental intermediate step towards protein structure and function prediction. We present new systems for the ab initio prediction of protein secondary structure and solvent accessibility, Porter 4.0 and PaleAle 4.0. Porter 4.0 predicts secondary structure correctly for 82.2% of residues. PaleAle 4.0's accuracy is...

Business strategy represents the choice of how to compete for competitive advantage (Porter, 1980, Porter, 1985). And Strategic Information Systems (SIS) shape (Rackoff et al., 1985, Wiseman, 1985) and enable (Bensaou and Venkatraman, 1995) that business strategy. SIS has been the focus of a large body of research and anecdotal descriptions (Chan and Huff, 1992, Porter and Millar, 1985, Wiseman...
