A PAM Decomposition of Weak CPM
… as its demodulation scheme. A PAM representation of weak CPM was developed which representation provided the necessary componenents to build a simplified PAM-based receiver that outperformed the EFTS limiter-discriminator, even in the presence of phase noise. The PAM …

Synthesis, characterization and application of polyacrylamide grafted bioflocculants (TMT-1-g-PAM 2 and TST-1-g-PAM 3)
… were varied. Optimum grades (TMT-1-g-PAM 2 and TST-1-g-PAM 3) were then characterized by intrinsic viscosity, elemental analysis, scanning electron microscopy (SEM), Fourier transform infrared (FTIR) spectroscopy, X-ray diffractometry (XRD) and thermogravimetric analysis (TGA). …

Mechanistic Studies of Peptidylglycine Alpha-Amidating Monooxygenase (PAM)
… Peptidylglycine alpha-amidating monooxygenase (PAM) is a bi-functional enzyme which catalyzes the activation of peptide pro-hormones. PAM also functionalizes long chain N-acylglycines suggesting a potential role in signaling as their respective fatty acid amides. As chain length increases for …

Rapid measurements of periphytic responses to nutrients using PAM fluorimetry
… the use of a pulse amplitude modulated (PAM) fluorometer for measuring biomass and photosynthetic activity in conjunction with NDS over several weeks. The results of this study suggest that this is a comparable methodology not only for measuring periphytic responses to nutrients but also …

Steady State and Theoretical Investigations of Peptidylglycine α-Amidating Monooxygenase (PAM)
… Peptidylglycine alpha-amidating monooxygenase (PAM) is a bi-functional enzyme which catalyzes the conversion of peptide pro-hormones to peptide hormones. PAM is the only known mammalian enzyme that catalyzes the necessary alpha-amidation to activate these peptide hormones. PAM has previously …

Low-jitter symbol timing recovery for M-ary QAM and PAM signals
… recovery schemes applicable to M-ary QAM and PAM signals. Franks and Bubrowski introduced highpass prefiltering and symmetric bandpass post-filtering for jitter-free operation of a symbol timing recovery scheme using a squarer for binary signaling. We show that the same conditions are also …

Intrazelluläre Mechanismen bei der durch den monomeren humanen IgM-Antikörper PAM-1 induzierten Apoptose
Der humane monoklonale IgM-Antikörper PAM-1 induziert in seiner monomeren Form sowohl in vivo als auch in vitro Apoptose an Magenkarzinomzellen. Er bindet hierbei an den post-transskriptionell modifizierten Rezeptor CFR-1, der auf nahezu allen epithelialen Karzinomzellen und deren Vorläuferläsionen …

Effects of polyacrylamide (PAM) and gypsum on irrigated and dryland potatoes (Solanum tuberosum L.).
… of irrigation, micronised polyacrylamide (PAM) and gypsum on the growth and yield of 'Ilam Hardy' potatoes in 2001-2002. At the final harvest, tuber yields were similar (59 500 kg ha⁻¹). Environmental factors dominated results, particularly January rainfall, which was 150% of the 16-year …

Transmission Capacity Improvement for Single Photon Avalanche Diode-based Optical Communication Using PAM Modulation
… for higher order pulse amplitude modulation (PAM) modulation with equalization is proposed. The method is verified by comparison with published experimental results. It is found that the Poisson model, previously used in the literature, fails to characterize the signal variation after …

Der humane monoklonale IgM-Antikörper PAM-1 wurde aus einem Patienten mit Magenkarzinom mit Hilfe der humanen Hybridomatechnik isoliert und bindet an eine neue, post-transkriptionell modifizierte Variante des CFR-1 Rezeptors. Dieser Rezeptor ist auf fast allen Karzinomen unabhängig von …

Mechanistic insight on a chimeric Cas9 protein's specificity for DNA target with 5 '-NAA-3' PAM
… that can recognize protospacer-adjacent motifs (PAMs) other than the canonical NGG discovered in wild-type Streptococcus pyogenes. While Cas nuclease engineering has largely yielded proteins with enhanced specificity for NGG and variations on G-containing PAMs, we were able to construct a …

Rarely Acquired Type II-A CRISPR-Cas Spacers Mediate Anti-Viral Immunity Through the Targeting of a Non-Canonical PAM Sequence
… motif, known as the protospacer adjacent motif (PAM). The PAM identifies the phage DNA as "foreign" and triggers the Cas nuclease, Cas9, to cleave the target phage DNA. Most of the spacers present in bacterial populations that survive phage infection target protospacers flanked by N-G-G PAMs. As …

The Utility of Foraminifera in Documenting Sediment Provenance for Overwash Deposits: A Case Study Using Sediments Deposited by Tropical Cyclone Pam In Vanuatu
… in March 2015 when Tropical Cyclone (TC) Pam made landfall on Vanuatu as a Category 5 storm, impacting coastlines with storm surges that produced high water marks up to 7 m above MSL and deposited sediments up to 400 m inland. We examined the foraminiferal assemblages contained within TC …

Effect of polyacrylamides on the physical properties of some light-textured soils.
… small concentrations of polyacrylamide or ‘PAM’ in the irrigation water, the crops seemed to do better. Furthermore the timing of irrigation events appeared to be more flexible on the PAM-treated properties. I found this intriguing and saw an opportunity to increase the lateral spread of …

Submicron-resolution Photoacoustic Microscopy of Endogenous Light-absorbing Biomolecules
… optical-resolution photoacoustic microscopy (OR-PAM) can achieve high spatial resolution, on the order of optical wavelength, at <1 mm depth in biological tissue (the optical ballistic regime). OR-PAM has been applied successfully to structural and functional imaging of blood vasculature and red …

Reduced Complexity Detection Methods for Continuous Phase Modulation
… is the well-known pulse amplitude modulation (PAM) representation of CPM, which was first proposed by Laurent. It is shown that the PAM representation also applies to multi-h CPM and ternary CPM, two previously unconsidered cases. In both cases it is shown that many PAM components may be …

Heterologous production of recombinant peptidylglycine α-amidating monooxygenase for the production of biosimilar α-amidated peptides
… Peptidylglycine α-amidating monooxygenase (PAM) is the only enzyme that catalyses the C-terminal amidation of peptides in vivo through its two catalytic cores, peptidylglycine α-hydroxylating monooxygenase (PHM) and peptidylglycine αamidating lyase (PAL). The cost and limited quantities of …
