P band in a rotating optical lattice
(The American Physical Society, 2008)We investigate the effects of rotation on the excited bands of a tightbinding lattice, focusing particularly on the first excited (p) band. Both the onsite energies and the hopping between lattice sites are modified by ... 
pcenter problems
(Springer, 2015)A pcenter is a minimax solution that consists in a set of p points that minimizes the maximum distance between a demand point and a closest point belonging to that set. We present different variants of that problem. We ... 
Pdopingfree InGaN/GaN lightemitting diode driven by threedimensional hole gas
(2013)Here, GaN/AlxGa1xN heterostructures with a graded AlN composition, completely lacking external pdoping, are designed and grown using metalorganicchemicalvapour deposition (MOCVD) system to realize threedimensional ... 
Phub maximal covering problem and extensions for gradual decay functions
(Bilkent University, 2013)Hubs are special facilities that serve as switching, transshipment and sorting nodes in many to many distribution systems. The hub location problem deals with the selection of the locations of hub facilities and finding ... 
The PHub maximal covering problem and extensions for gradual decay functions
(Elsevier, 2015)The phub maximal covering problem aims to find the best locations for hubs so as to maximize demands within a coverage distance with a predetermined number of hubs. Classically, the problem is defined in the framework of ... 
phub median problem for noncomplete networks
(Elsevier, 2018)Most hub location studies in the literature use a completenetwork structure as an input in developing optimization models. This starting point is not necessarily from assuming that the underlying realworld network (e.g., ... 
P/E and pricetobook ratio as predictors of stock returns in emerging equity markets
(Institutional Investor, 200008) 
p53 but not p16(INK4a) induces growth arrest in retinoblastomadeficient hepatocellular carcinoma cells
(Elsevier, 200008)Background/Aim: Both p16(INK4a) and p53 proteins are negative regulators of the cell cycle. In human hepatocellular carcinomas (HCC), the loss of function of p53, retinoblastoma (pRb) and p16(INK4a) genes by different ... 
p53 codon 72 polymorphism in bladder cancerNo evidence of association with increased risk or invasiveness
(Springer, 2001)We studied the effect of the p53 gene Arg72Pro polymorphism on bladder cancer susceptibility in a case control study of 121 bladder cancer patients and 114 agesex matched controls to determine whether this polymorphism ... 
p53 mutation as a source of aberrant βcatenin accumulation in cancer cells
(2002)βcatenin is involved in both cellcell interactions and wnt pathwaydependent cell fate determination through its interactions with Ecadherin and TCF/LEF transcription factors, respectively. Cytoplasmic/nuclear levels ... 
p53 mutation with frequent novel codons but not a mutator phenotype in BRCA1and BRCA2associated breast tumours
(Nature Publishing Group, 1998)The status of p53 was investigated in breast tumours arising in germline carriers of mutant alleles of BRCA1 and BRCA2 and in a control series of sporadic breast tumours. p53 expression was detected in 20/26 (77%) BRCA1, ... 
p53 mutations as a source of aberrant Betacatenin accumulation in cancer cells
(Bilkent University, 2002)βcatenin is involved in both cellcell interactions and wnt pathwaydependent cell fate determination through its interactions with Ecadherin and TCF/LEF transcription factors, respectively. Cytoplasmic/nuclear levels ... 
p53 mutations as fingerprints of environmental carcinogens
(2000)Mutations of the p53 tumor suppressor gene occur in a great majority of human cancers. The protein product of p53 gene is involved in DNA damage response. Consequently, p53 gene may be a preferred target for environmental ... 
p53 polymorphism influences response in cancer chemotheraphy via modulation of p73dependent apoptosis
(Elsevier, 200304)Intact p73 function is shown to be an important determinant of cellular sensitivity to anticancer agents. Inhibition of p73 function by dominantnegative proteins or by mutant p53 abrogates apoptosis and cytotoxicity induced ... 
Packet loss analysis of synchronous bufferless optical switch with shared limited range wavelength converters
(IEEE, 2007)Application of synchronous optical switches in Optical Packet/Burst switched networks is considered. The shared per node architectural concept, where wavelength converters are shared among all input and output channels, ... 
Pagetoprocessor assignment techniques for parallel crawlers
(Bilkent University, 2004)In less than a decade, the World Wide Web has evolved from a research project to a cultural phenomena effective in almost every facet of our society. The increase in the popularity and usage of the Web enforced an increase ... 
Painleve test and the Painleve equations hierarchies
(Bilkent University, 2001)Recently there has been a considerable interest in obtaining higher order ordinary differential equations having the Painleve property. In this thesis, starting from the first, the second and the third Painleve transcendents ... 
Painlevé test and higher order differential equations
(Taylor & Francis Asia Pacific, 2002)Starting from the second Painleve equation, we obtain Painlev e type equations of higher order by using the singular point analysis. 
Painlevé test and the first Painlevé hierarchy
(1999)Starting from the first Painlevé equation, Painlevé type equations of higher order are obtained by using the singular point analysis. 
The pair correlation of zeros of Dirichlet Lfunctions and primes in arithmetic progressions
(SpringerVerlag, 1991)We define a function which correlates the zeros of two Dirichlet Lfunctions to the modulus q and we prove an asymptotic estimate for averages of the pair correlation functions over all pairs of characters to (mod q). An ...
