We study the complexity classes P and NP through a semigroup fP (“polynomial-time functions”), consisting of all polynomially balanced polynomial-time computable partial functions. Then P 6= NP iff fP is a non-regular semigroup. The one-way functions considered here are based on worstcase complexity (they are not cryptographic); they are the non-regular elements of fP. We prove various properti...

Glover and Sherali (2003) introduced a wide class of Foundation-Penalty (FP) cuts for GUB and ordinary mixed-integer programs. The FP cuts are easy to generate by exploiting routine branch-and-bound penalty calculations, and encompass other classical cuts such as disjunctive cuts, lift-and-project cuts, convexity cuts, Gomory cuts, and mixed-integer rounding cuts. Here we focus on two special c...

The Epstein-Barr virus BamHI F promoter (Fp) was previously identified as the putative EBNA 1 gene promoter in group 1 Burkitt's lymphoma (BL) cell lines. Fp has also been shown to be activated in Epstein-Barr virus-positive B-cell lines following induction of the viral productive cycle (A. L. Lear, M. Rowe, M. G. Kurilla, S. Lee, S. Henderson, E. Kieff, and A. B. Rickinson, J. Virol. 66:7461-7...

OBJECTIVES Family planning (FP) clinics are important access points for cervical cancer screening and referrals for follow-up care for abnormal Papanicolaou (Pap) smears for a substantial number of U.S. women. Because little is known about referral and facilitation practices in these clinics or client action based on referrals, we sought to determine FP provider referral and facilitation practi...

While Fabry-Pérot (FP) resonances and Moiré superlattices are intensively studied in graphene on hexagonal boron nitride (hBN), the two effects have not been discussed in their coexistence. Here we investigate the FP oscillations in a ballistic pnp-junctions in the presence and absence of a Moiré superlattice. First, we address the effect of the smoothness of the confining potential on the visi...

Let r be a positive integer, let p be a prime and Fp denote an algebraic closure of the prime field Fp. After observing that the principal block B of FpPSU(3, p) is stably equivalent of Morita type to its Brauer correspondent b, we compute the radical series of the center Z(b), and, using GAP, the radical series of Z(B) in the cases p ∈ {3, 4, 5, 7, 8}. In these cases, the dimensions of the las...

Femoropopliteal (FP) artery-in stent restenosis (ISR) is a daunting management problem that we continue to face. FP artery-ISR rates after primary stent implantation are relatively high. Although repeat FP artery-ISR and the need for additional interventions remain all too common, little consensus exists regarding the best treatment algorithm. In this article, we review the limitations of the c...

A protease, freesia protease (FP)-A, was purified to electrophoretic homogeneity from regular freesia (Freesia reflacta) corms in harvest time. The Mr of FP-A was estimated to be 24 k by SDS-PAGE. The optimum pH of the enzyme was 8.0 using a casein substrate. These enzymes were strongly inhibited by p-chloromercuribenzoic acid but not by phenylmethane-sulfonylfluoride and EDTA. These results in...

Fenpyroximate (FP), an acaricide, is widely used in the prevention of acarids (mites) in fruit plant gardens. In this study, the acute toxic effects of sublethal concentrations of FP were investigated using adult guppy (Poecilia reticulata PETERS, 1859). Guppy adults were exposed to sublethal FP concentrations (15, 25, and 150 μgl) during 48 hours (n:10). Sublethal exposures were made according...

Over 150,000 reproductive age individuals face fertility-threatening cancer treatments each year. Improved detection and treatment of cancer in reproductive-age patients have greatly increased the long-term survival and made it possible for these individuals to consider their long-term quality-of-life after cancer including having biologic offspring. Various methods of fertility preservation (F...
