A linearized, high efficiency 2.7 GHz wideband Doherty power amplifier with Class-J based performance enhancement (2015)

This paper outlines the approach used for the design of a high efficiency 30W Doherty power amplifier. The benefits of exploiting the inherent device nonlinearities for Class-J PA operation are discussed, specifically in the case of Doherty amplifiers. The combination of Class-J modes and internal device matching ensures high performance in a compact, cost-sensitive Doherty amplifier design. To validate the discussed theory, a simple 2.7 GHz symmetric Doherty PA was designed and fabricated, producing 30W of output power with greater than 60% efficiency at 6 dB back-off. The PA was subsequently linearized using a wideband 20 MHz LTE signal with a PAPR of 6.5 dB. For an ACPR of <;-50 dBc, 8W of average output power was obtained with a corresponding efficiency of 60%.
Neural Decoding of Visual Imagery During Sleep (2013)

Visual imagery during sleep has long been a topic of persistent speculation, but its private nature has hampered objective analysis. Here we present a neural decoding approach in which machine-learning models predict the contents of visual imagery during the sleep-onset period, given measured brain activity, by discovering links between human functional magnetic resonance imaging patterns and verbal reports with the assistance of lexical and image databases. Decoding models trained on stimulus-induced brain activity in visual cortical areas showed accurate classification, detection, and identification of contents. Our findings demonstrate that specific visual experience during sleep is represented by brain activity patterns shared by stimulus perception, providing a means to uncover subjective contents of dreaming using objective neural measurement.
A new method for the estimate of $\vec{H_0}$ from quadruply imaged gravitational lens systems (2002)

We present a new method to estimate the Hubble constant H0 from the measured time delays in quadruply imaged gravitational lens systems. We show how it is possible to get an estimate of H0 without the need to completely reconstruct the lensing potential thus avoiding any a priori hypothesis on the expression of the galaxy lens model. Our method only needs to assume that the lens potential may be expressed as , whatever the shape function is, and it is thus able to fully explore the degeneracy in the mass models taking also into account the presence of an external shear. We test the method on simulated cases and show that it does work well in recovering the correct value of the slope α of the radial profile and of the Hubble constant H0. Then, we apply the same method to the real quadruple lenses PG 1115+080 and B1422+231 obtaining (68% CL).

Absence epilepsy subnetworks revealed by event‐related independent components analysis of functional magnetic resonance imaging (2013)

The eICA results support previous findings that the earliest activity associated with GSW may be in posterior cortical regions and provide new evidence that the thalamostriate network may play a more important role in the generation of GSW than suggested by previous studies.
Dielectric Wide-Band Nonpolarizing Prism Beam Splitter (1992)

It is difficult to attain a nonpolarizing assembly of optical thin films because the optical admittance of layer for S polarizing component of light waves is not equal to that for P polarizing component when the waves are obliquely incident upon the surface of the layer. The dependence of the admittances on the refraction angle of the waves inside the layer is as fellows: where n 1 is the refraction index of the layer, and θ 1 , the refraction angle.

Microdissection genotyping of mixed glial and primitive neuroectodermal central nervous system neoplasm. (2004)

A 22-year-old man with previous radiation treatment for childhood astrocytoma underwent resection of a right parietooccipital lesion. Histopathology revealed a malignant neoplasm with areas of astrocytic and primitive neuroectodermal components. To resolve the relationship and cellular origin, representative tissue was microdissected from several targets, obtaining a balanced mixture of each element. Nonneoplastic brain parenchyma was separately microdissected to determine polymorphic marker informativeness and to serve as an internal negative control. Despite the relatively small quantity of tissue removed for each microdissection target, sufficient material was available for reliable, balanced, polymerase chain reaction-format genotyping encompassing a panel of tumor suppressor genes and genetic loci associated with these forms of neoplasia. The findings revealed distinct discordant genotypic profiles for each of the neoplastic components. The efficacy of the approach used for molecular analysis of this complex neoplasm and the implication of the genotypic findings are discussed.
Synthesis and Spectroscopic Identification of Ethylidyne Adsorbed on Ni(111) (1998)

The interaction of ethylene adsorbed on Ni(111) with gas-phase H atoms has been investigated. The major adsorbed reaction product is identified by high-resolution electron energy loss spectroscopy to be ethylidyne (C−CH3). This study is the first direct spectroscopic observation of a C−CH3 species adsorbed on Ni in an ultrahigh-vacuum environment. Spectra of four isotopomers, C−CH3, 13C−13CH3, C−CD3, and 13C−13CD3, are reported, and a complete and consistent vibrational assignment of their fundamental modes is presented. Based on this assignment, a force field is derived from the measured vibrational frequencies using a normal-modes analysis and is found to be in good agreement with that deduced from IR spectra of an ethylidyne species in an organometallic complex. Inspection of the eigenvectors of the normal-mode displacements reveals that substantial mixing of harmonic bond motions is the origin of the unusual upshift in frequency of the C−C stretching mode upon deuteration. A quantitative determination of the relative dynamic bond dipole moments demonstrates that the changes in intensity and dipole activity of the C−C stretching and symmetric CH3 deformation modes upon deuteration, phenomena common to all C−CD3 spectra, also arise from extensive mixing of bond motions. A detailed analysis of the spectra strongly suggests a C3v or C3 local environment for ethylidyne and a 3-fold hollow adsorption site.
Using Stable Free Radicals to Obtain Unique and Clinically Useful Data<i>In Vivo</i>in Human Subjects (2016)

This paper attempts to: (1) provide a critical overview of the challenges and opportunities to extend electron paramagnetic resonance (EPR) into practical applications in human subjects, based on EPR measurements made in vivo; (2) summarize the clinical applications of EPR for improving treatments in cancer, wound healing and diabetic care, emphasizing EPR's unique capability to measure tissue oxygen repeatedly and with particular sensitivity to hypoxia and (3) summarize the capabilities of in vivo EPR to measure radiation dose for triage and medical guidance after a large-scale radiation exposure. The conclusion is that while still at a relatively early stage of its development and availability, clinical applications of EPR already have demonstrated significant value and the field is likely to grow in both the extent of its applications and its impact on significant problems.

Resonance enhanced two-photon ionization studies in a supersonic molecular beam: Bromobenzene and iodobenzene (1980)

The 1B2(ππ*)←1A1 absorptions of two monosubstituted halobenzenes have been investigated using resonance enhanced two-photon ionization in a pulsed supersonic molecular beam. Detection of the photoions was accomplished by means of a time-of-flight mass spectrometer. The 1B2←1A1 system of bromobenzene has been observed with good sensitivity using this technique, even though the total decay rate of the 1B2 state is greater than 1×1011 sec−1. No ion signal was observed when the same transition was probed in iodobenzene, allowing us to place a lower limit on its decay rate of 4×1013 sec−1.
Sequence-specific proton NMR assignments and secondary structure in the sea anemone polypeptide Stichodactyla helianthus neurotoxin I (1989)

Sequence-specific assignments are reported for the 500-MHz 1H nuclear magnetic resonance (NMR) spectrum of the 48-residue polypeptide neurotoxin I from the sea anemone Stichodactyla helianthus (Sh I). Spin systems were first identified by using two-dimensional relayed or multiple quantum filtered correlation spectroscopy, double quantum spectroscopy, and spin lock experiments. Specific resonance assignments were then obtained from nuclear Overhauser enhancement (NOE) connectivities between protons from residues adjacent in the amino acid sequence. Of a total of 265 potentially observable resonances, 248 (i.e., 94%) were assigned, arising from 39 completely and 9 partially assigned amino acid spin systems. The secondary structure of Sh I was defined on the basis of the pattern of sequential NOE connectivities, NOEs between protons on separate strands of the polypeptide backbone, and backbone amide exchange rates. Sh I contains a four-stranded antiparallel beta-sheet encompassing residues 1-5, 16-24, 30-33, and 40-46, with a beta-bulge at residues 17 and 18 and a reverse turn, probably a type II beta-turn, involving residues 27-30. No evidence of alpha-helical structure was found.
Hydrocarbon-like and oxygenated organic aerosols in Pittsburgh: insights into sources and processes of organic aerosols (2005)

Abstract. A recently developed algorithm (Zhang et al., 2005) has been applied to deconvolve the mass spectra of organic aerosols acquired with the Aerosol Mass Spectrometer (AMS) in Pittsburgh during September 2002. The results are used here to characterize the mass concentrations, size distributions, and mass spectra of hydrocarbon-like and oxygenated organic aerosol (HOA and OOA, respectively). HOA accounts for 34% of the measured organic aerosol mass and OOA accounts for 66%. The mass concentrations of HOA demonstrate a prominent diurnal profile that peaks in the morning during the rush hour and decreases with the rise of the boundary layer. The diurnal profile of OOA is relatively flat and resembles those of SO42− and NH4+. The size distribution of HOA shows a distinct ultrafine mode that is commonly associated with fresh emissions while OOA is generally concentrated in the accumulation mode and appears to be mostly internally mixed with the inorganic ions, such as SO42− and NH4+. These observations suggest that HOA is likely primary aerosol from local, combustion-related emissions and that OOA is secondary organic aerosol (SOA) influenced by regional contributions. There is strong evidence of the direct correspondence of OOA to SOA during an intense new particle formation and growth event, when condensational growth of OOA was observed. The fact that the OOA mass spectrum from this event is very similar to that from the entire study suggests that the majority of OOA in Pittsburgh is likely SOA. O3 appears to be a poor indicator for OOA concentration while SO42− is a relatively good surrogate for this dataset. Since the diurnal averages of HOA track those of CO during day time, oxidation/aging of HOA appears to be very small on the time scale of several hours. Based on extracted mass spectra and the likely elemental compositions of major m/z's, the organic mass to organic carbon ratios (OM:OC) of HOA and OOA are estimated at 1.2 and 2.2 μg/μgC, respectively, leading to an average OM:OC ratio of 1.8 for submicron OA in Pittsburgh during September. The C:O ratio of OOA is estimated at 1:0.8. The carbon contents in HOA and OOA estimated accordingly correlate well to primary and secondary organic carbon, respectively, estimated by the OC/EC tracer technique (assuming POC-to-EC ratio=1). In addition, the total carbon concentrations estimated from the AMS data agree well with those measured by the Sunset Laboratory Carbon analyzer (r2=0.87; slope=1.01±0.11). Our results represent the first direct estimate of the OM:OC ratio from highly time-resolved chemical composition measurements.
MALDI imaging in Fabry nephropathy: a multicenter study (2019)

The current study evaluates the application of histology and in situ proteomics (MALDI-MSI) in Fabry nephropathy (FN), showing investigative and classification role for this coupled approach. A retrospective series of 14 formalin fixed paraffin embedded (FFPE) renal biopsies with diagnosis of FN and 1 biopsy from a patient bearing a galactosidase-α (GLA) genetic variant of unknown significance (GVUS, c.376A>G) have been classified for clinical characteristics. Groups were compared for histological differences (following the ISGFN scoring system). Moreover, renal biopsies from these cases have been analyzed with MALDI-MSI as previously described to find proteomic signatures among different mutations and phenotypes. Comparison of clinical features revealed lower mean 24 h proteinuria in females (225 mg/24 h) than in males (1477.5 mg/24 h, p = 0.006). As for clinical characteristics, females significantly differed from males only for lower arterial sclerosis, with a mean value of 0.82 vs. 1.05 (p = 0.001). Proteomic analysis demonstrated specific signatures in different subgroups of FN patients. Moreover, MALDI correctly classified cases with undetermined mutation or GVUS. The present study demonstrated the feasible application of MALDI-MSI in the analysis of FN FFPE renal biopsies, allowing the detection of putative signatures for phenotypic distinction and demonstrating genetic classification capabilities.
Comparison of mouse and human genomes followed by experimental verification yields an estimated 1,019 additional genes (2003)

A primary motivation for sequencing the mouse genome was to accelerate the discovery of mammalian genes by using sequence conservation between mouse and human to identify coding exons. Achieving this goal proved challenging because of the large proportion of the mouse and human genomes that is apparently conserved but apparently does not code for protein. We developed a two-stage procedure that exploits the mouse and human genome sequences to produce a set of genes with a much higher rate of experimental verification than previously reported prediction methods. RT-PCR amplification and direct sequencing applied to an initial sample of mouse predictions that do not overlap previously known genes verified the regions flanking one intron in 139 predictions, with verification rates reaching 76%. On average, the confirmed predictions show more restricted expression patterns than the mouse orthologs of known human genes, and two-thirds lack homologs in fish genomes, demonstrating the sensitivity of this dual-genome approach to hard-to-find genes. We verified 112 previously unknown homologs of known proteins, including two homeobox proteins relevant to developmental biology, an aquaporin, and a homolog of dystrophin. We estimate that transcription and splicing can be verified for >1,000 gene predictions identified by this method that do not overlap known genes. This is likely to constitute a significant fraction of the previously unknown, multiexon mammalian genes.

Shared Subunits of Tetrahymena Telomerase Holoenzyme and Replication Protein A Have Different Functions in Different Cellular Complexes (2016)

In most eukaryotes, telomere maintenance relies on telomeric repeat synthesis by a reverse transcriptase named telomerase. To synthesize telomeric repeats, the catalytic subunit telomerase reverse transcriptase (TERT) uses the RNA subunit (TER) as a template. In the ciliate Tetrahymena thermophila, the telomerase holoenzyme consists of TER, TERT, and eight additional proteins, including the telomeric repeat single-stranded DNA-binding protein Teb1 and its heterotrimer partners Teb2 and Teb3. Teb1 is paralogous to the large subunit of the general single-stranded DNA binding heterotrimer replication protein A (RPA). Little is known about the function of Teb2 and Teb3, which are structurally homologous to the RPA middle and small subunits, respectively. Here, epitope-tagging Teb2 and Teb3 expressed at their endogenous gene loci enabled affinity purifications that revealed that, unlike other Tetrahymena telomerase holoenzyme subunits, Teb2 and Teb3 are not telomerase-specific. Teb2 and Teb3 assembled into other heterotrimer complexes, which when recombinantly expressed had the general single-stranded DNA binding activity of RPA complexes, unlike the telomere-specific DNA binding of Teb1 or the TEB heterotrimer of Teb1, Teb2, and Teb3. TEB had no more DNA binding affinity than Teb1 alone. In contrast, heterotrimers reconstituted with Teb2 and Teb3 and two other Tetrahymena RPA large subunit paralogs had higher DNA binding affinity than their large subunit alone. Teb1 and TEB, but not RPA, increased telomerase processivity. We conclude that in the telomerase holoenzyme, instead of binding DNA, Teb2 and Teb3 are Teb1 assembly factors. These findings demonstrate that Tetrahymena telomerase holoenzyme and RPA complexes share subunits and that RPA subunits have distinct functions in different heterotrimer assemblies.
Prediction of Microcracking in Laser Overly Welds of Alloy 690 to Type 316L Stainless Steel (2011)

The occurrence of ductility-dip crack in the laser overlay welds of alloy 690 to type 316L stainless steel was predicted by the mechanical and metallurgical approaches. Ductility-dip temperature ranges (DTRs) of alloy 690 laser overlay welds were estimated by Varestraint test during GTA welding. The grain boundary segregation of impurity elements such as P and S was numerically analyzed based on the non-equilibrium cosegregation theory when the welding speed and the amounts of P and S in the weld metal were varied. In accordance with the repression approximation between the DTR and the calculated grain boundary concentrations of P and S, the DTRs of alloy 690 were computed in laser overlay welding. The estimated DTR in laser overlay welds was reduced with an increase in welding speed and with a decrease in the amounts of P and S in the weld metal. Ductility-dip cracking in laser overlay welds was predicted by the plastic strain-temperature curve intersected the DTR. The plastic strain in laser overlay welding was numerically analyzed using the thermo elasto-plastic finite element method. The plastic strain-temperature curve in laser overlay welds intersected the DTR at decreased welding speed and increased (P+S) content in the weld metal. The predicted results of ductility-dip cracking in laser overlay welds were approximately consistent with experiment results. It follows that ductility-dip cracking in laser overlay welds could be successfully predicted based on the estimated DTR from grain boundary segregation analysis combined with the computed plastic strain by FEM analysis.
Determination of <i>m</i>, <i>e</i>/<i>m</i>, and <i>M</i> <i>p</i>/<i>m</i> by the study of the isotope structure in hydrogen (1975)

Using a commercially available hydrogen–deuterium light source and a 3.4-m Ebert plane grating spectrograph, the wavelengths of the first six pairs of the Balmer series are obtained. From the results, first, the series limit, Rydberg constant, and ionization potential of hydrogen are found from the graph. Then, by means of formulas involving wave numbers of hydrogen and deuterium and by knowing the Faraday constant, the values of m, e/m, and Mp/m are determined. All the values are found to be in good agreement with accepted values. From the results, this experiment is recommended for an upper division optics and spectroscopy or quantum physics laboratory.
