P And S Wave Velocity Determination
(Massachusetts Institute of Technology. Earth Resources Laboratory, 1983)There are three general methods that can be used to determine formation velocities from full waveform logs. The first approach is to make use of the data from the entire waveform. This type of velocity analysis is performed ... 
P and SV waves 3D Numerical Modeling of AVOA from Heterogeneous Fractured Reservoirs
(Massachusetts Institute of Technology. Earth Resources Laboratory, 1997)We study the effects of fractureinduced anisotropy and lateral fracture density heterogeneity on the reflected P and SV wave amplitude variation with offset and azimuth (AVOA), using 3D finitedifference simulations. The ... 
The (p,n) reaction on 9Be and 17O at 135 MeV
(Massachusetts Institute of Technology, 1985) 
P and S wave tomography of the crust and uppermost mantle in China and surrounding areas
(Massachusetts Institute of Technology, 2005)This thesis involves inverting the seismic structure of the crust and uppermost mantle in China from the P and Swave traveltime tomography. The main contributions of this research are: 1) introducing the adaptive moving ... 
padic interpolation of iterates
(Oxford University Press, 201403)Extending work of Bell and of Bell, Ghioca, and Tucker, we prove that for a padic analytic selfmap f on a closed unit polydisk, if every coefficient of f(x)−x has valuation greater than that of p [1over (p−1)], then the ... 
The padic local langlands conjecture
(Massachusetts Institute of Technology, 2005)Let k be a padic field. Split reductive groups over k can be described up to k isomorphism by a based root datum alone, but other groups, called rational forms of the split group, involve an action of the Galois group ... 
padic modular forms over Shimura curves over Q
(Massachusetts Institute of Technology, 1999) 
pChannel gallium nitride transistor on Si substrate
(Massachusetts Institute of Technology, 2018)Gallium Nitride, a wide bandgap (3.4 eV) semiconductor, has outstanding attributes, such as, high breakdown electric field, high electron mobility, which make it suitable for applications requiring high power and high ... 
PN junction microwave phase modulators.
(Massachusetts Institute of Technology, 1972) 
The PNorm Push: A Simple Convex Ranking Algorithm that Concentrates at the Top of the List
(MIT Press, 200910)We are interested in supervised ranking algorithms that perform especially well near the top of the ranked list, and are only required to perform sufficiently well on the rest of the list. In this work, we provide a ... 
The pparity conjecture for elliptic curves with a pisogeny
(Walter de Gruyter, 201406)For an elliptic curve E over a number field K, one consequence of the Birch and SwinnertonDyer conjecture is the parity conjecture: the global root number matches the parity of the MordellWeil rank. Assuming finiteness ... 
PTAXI : enforcing memory safety with programmable tagged architecture
(Massachusetts Institute of Technology, 2016)Buffer overflow is a wellknown problem that remains a threat to software security. With the advancement of codereuse attacks and returnoriented programming (ROP), it becomes problematic to protect a program from being ... 
Pwave electrical alternans as an indicator of paroxysmal atrial fibrillation
(Massachusetts Institute of Technology, 1999)Pwave electrical alternans is a beat to beat alternation in the morphology of the Pwave, the wave in an electrocardiogram corresponding to atrial depolarization. In this investigation, software to measure pwave alternans ... 
Pwave ππ scattering and the ρ resonance from lattice QCD
(American Physical Society, 201708)We calculate the parameters describing elastic I=1, Pwave ππ scattering using lattice QCD with 2+1 flavors of clover fermions. Our calculation is performed with a pion mass of m[subscript π]≈320 MeV and a lattice size ...

P22 arc repressor : cooperative DNA binding and transcriptional regulation
(Massachusetts Institute of Technology, 1996) 
P22 arcenergetics and cooperativity of DNA binding
(Massachusetts Institute of Technology, 1994) 
A p38alphaSelective Chemosensor for use in Unfractionated Cell Lysates
(American Chemical Society, 201009)Recent efforts have identified the p38alpha Ser/Thr kinase as a potential target for the treatment of inflammatory diseases as well as nonsmall cell lung carcinoma. Despite the significance of p38alpha, no direct activity ... 
The p53 binding protein PDCD5 is not ratelimiting in DNA damage induced cell death
(Nature Publishing Group, 201506)The tumour suppressor p53 is an important mediator of cell cycle arrest and apoptosis in response to DNA damage, acting mainly by transcriptional regulation of specific target genes. The exact details how p53 modulates ... 
p53 constrains progression to anaplastic thyroid carcinoma in a Brafmutant mouse model of papillary thyroid cancer
(National Academy of Sciences (U.S.), 201404)Anaplastic thyroid carcinoma (ATC) has among the worst prognoses of any solid malignancy. The low incidence of the disease has in part precluded systematic clinical trials and tissue collection, and there has been little ...
