Evidence for local and nonlocal barotropic responses to atmospheric forcing during BEMPEX (1990)

The coherence between single bottom pressure and barotropic velocity records collected in the North Pacific during BEMPEX and air pressure, wind stress, and stress curl derived from FNOC products are examined over the 200‐1 day period band. Strong coherence between the bottom pressure and all atmospheric variables is seen, nonlocal coherence (maximum up to 1000 km to the southeast) dominating at periods longer than ≈10 d and coherence being prevalent at shorter periods, consistent with predictions from existing models of atmospherically‐forced barotropic motion. The azimuth of the nonlocal coherence maximum relative to the ocean station is a function of frequency, which is not expected from the models. The coherence between the barotropic velocity (as measured by the electric field) and the atmospheric variables is weaker, but nonlocal coherence with the wind stress and wind stress curl at periods greater than a week, and local coherence with the wind stress at shorter periods, is statistically significant.
First clinical evaluation of a luminal self-expanding shield in patients with intermediate coronary lesions (2011)

Implantation of the LS in non-complex coronary lesions of intermediate severity was feasible, safe, and resulted in low rates of late loss and restenosis. IVUS analysis at nine months showed favourable mechanical properties of the LS without evidence of late device over-expansion.
Role of catheter ablation for supraventricular tachyarrhythmias, with emphasis on atrial flutter and atrial tachycardia (1994)

Catheter ablation techniques using radiofrequency current have become an accepted form of treatment for a variety of supraventricular tachycardias. The results are excellent in patients with preexcitation syndromes and as the complication rate is low, catheter ablation has become the first line of treatment for these disorders. In atrioventricular nodal reentry, a selective ablation of the fast or slow pathway is feasible. Ablation of the slow pathway guided by electrophysiologic markers appears to be safer with the use of a very low number of radiofrequency applications. Experience with atrial tachycardia remains limited but developments appear promising. Lastly, atrial flutter has become a growing indication for catheter ablation techniques using anatomical approaches. A high success rate can be achieved initially, but the technique is limited by a 20% recurrence rate and the late occurrence of atrial fibrillation.
An Alteration in the Lateral Geniculate Nucleus of Experimental Glaucoma Monkeys: In vivo Positron Emission Tomography Imaging of Glial Activation (2012)

We examined lateral geniculate nucleus (LGN) degeneration as an indicator for possible diagnosis of glaucoma in experimental glaucoma monkeys using positron emission tomography (PET). Chronic intraocular pressure (IOP) elevation was induced by laser trabeculoplasty in the left eyes of 5 cynomolgus monkeys. Glial cell activation was detected by PET imaging with [(11)C]PK11195, a PET ligand for peripheral-type benzodiazepine receptor (PBR), before and at 4 weeks after laser treatment (moderate glaucoma stage). At mild, moderate, and advanced experimental glaucoma stages (classified by histological changes based on the extent of axonal loss), brains were stained with cresyl violet, or antibodies against PBR, Iba-1 (a microglial marker), and GFAP (an activated astrocyte marker). In laser-treated eyes, IOP was persistently elevated throughout all observation periods. PET imaging showed increased [(11)C]PK11195 binding potential in the bilateral LGN at 4 weeks after laser treatment; the increase in the ipsilateral LGN was statistically significant (P<0.05, n = 4). Immunostaining showed bilateral activations of microglia and astrocytes in LGN layers receiving input from the laser-treated eye. PBR-positive cells were observed in LGN layers receiving input from laser-treated eye at all experimental glaucoma stages including the mild glaucoma stage and their localization coincided with Iba-1 positive microglia and GFAP-positive astrocytes. These data suggest that glial activation occurs in the LGN at a mild glaucoma stage, and that the LGN degeneration could be detected by a PET imaging with [(11)C]PK11195 during the moderate experimental glaucoma stage after unilateral ocular hypertension. Therefore, activated glial markers such as PBR in the LGN may be useful in noninvasive molecular imaging for diagnosis of glaucoma.
Implications of Seed Vault Storage Strategies for Conservation of Seed Bacterial Microbiomes (2021)

Global seed vaults are important, as they conserve plant genetic resources for future breeding to improve crop yield and quality and to overcome biotic and abiotic stresses. However, little is known about the impact of standard storage procedures, such as seed drying and cold storage on the seed bacterial community, and the ability to recover seed-associated bacteria after storage. In this study, soybean [<i>Glycine max</i> (L.) Merr.] seeds were analyzed to characterize changes in the bacterial community composition and culturability under varying storage conditions. The <i>G. max</i> bacterial microbiome was analyzed from undried seed, dried seed, and seed stored for 0, 3, 6, and 14months. Storage temperatures consisted of -20°C, 4°C, and room temperature (RT), with -20°C being commonly used in seed storage vaults globally. The seed microbiome of <i>G. max</i> was dominated by <i>Gammaproteobacteria</i> under all conditions. Undried seed was dominated by <i>Pantoea</i> (33.9%) and <i>Pseudomonas</i> (51.1%); however, following drying, the abundance of <i>Pseudomonas</i> declined significantly (0.9%), <i>Pantoea</i> increased significantly (73.6%), and four genera previously identified including <i>Pajaroellobacter</i>, <i>Nesterenkonia</i>, env.OPS_17, and <i>Acidibacter</i> were undetectable. Subsequent storage at RT, 4, or -20°C maintained high-abundance Genera at the majority of time points, although RT caused greater fluctuations in abundances. For many of the low-abundance Genera, storage at -20°C resulted in their gradual disappearance, whereas storage at 4°C or RT resulted in their more rapid disappearance. The changes in seed bacterial composition were reflected by cultured bacterial taxa obtained from the stored <i>G. max</i> seed. The main taxa were largely culturable and had similar relative abundance, while many, but not all, of the low-abundance taxa were also culturable. Overall, these results indicate that the initial seed drying affects the seed bacterial composition, suggesting that microbial isolation prior to seed drying is recommended to conserve these microbes. The standard seed storage condition of -20°C is most suitable for conservation of the bacterial seed microbiome, as this storage temperature slows down the loss of seed bacterial diversity over longer time periods, particularly low-abundance taxa.
The application of computational chemistry to lignin (2017)

Computational chemical methods have become an important technique in the examination of the structure and reactivity of lignin. The calculations can be based either on classical or quantum mechanics, with concomitant differences in computational intensity and size restrictions. The current paper will concentrate on results developed from the latter type of calculations for lignin model compounds. These methods can provide information on molecular geometry, thermodynamic properties, kinetics and electronic structure. Using density functional theory, the energies associated with bond dissociation and radical oxidation have been determined for β-O-4 dimers and trimers, pinoresinols, dibenzodioxocins, catecholalcohol based dimers, spirodienones, and combinations with tricin, catechins and epicatechins. Ongoing work is concerned with homo-coupled ferulates and cross-coupled lignin-ferulates. Exhaustive examinations of stereochemistry reveals the existence of thermodynamic differences with configuration.
Reformation of fine powdery materials through mechanochmiecal effects. II. Change in the sintering behavior due to mechanical activation. (1984)

Fine grained, well-dispersed pure α-Al2O3 was ground in a centrifugal ballmill, compressed under 18 and 100MPa, and fired in air at 1050-1550°C. For dense compacts, the sinterability of the activated material was higher up to the relative density, ρF, 85%. However, ρF was much lower for the ground material, when the compact was made at a lower pressure, presumably because of the inhomogeneity of the compact including hard aggregates. SEM observation revealed that the appreciable neck-and grain growth took place at temperatures as low as 1100°C for the activated material due to the enhanced surface diffusion.
Multi‐scale network regression for brain‐phenotype associations (2020)

Brain networks are increasingly characterized at different scales, including summary statistics, community connectivity, and individual edges. While research relating brain networks to behavioral measurements has yielded many insights into brain-phenotype relationships, common analytical approaches only consider network information at a single scale. Here, we designed, implemented, and deployed Multi-Scale Network Regression (MSNR), a penalized multivariate approach for modeling brain networks that explicitly respects both edge- and community-level information by assuming a low rank and sparse structure, both encouraging less complex and more interpretable modeling. Capitalizing on a large neuroimaging cohort (n = 1, 051), we demonstrate that MSNR recapitulates interpretable and statistically significant connectivity patterns associated with brain development, sex differences, and motion-related artifacts. Compared to single-scale methods, MSNR achieves a balance between prediction performance and model complexity, with improved interpretability. Together, by jointly exploiting both edge- and community-level information, MSNR has the potential to yield novel insights into brain-behavior relationships.
The conformation of NAD + bound to lactate dehydrogenase determined by nuclear magnetic resonance with suppression of spin diffusion (1997)

We have reinvestigated the conformation of NAD+ bound to dogfish lactate dehydrogenase (LDH) by using an NMR experiment that allows one to exploit nuclear Overhauser effects to determine internuclear distances between pairs of protons, without perturbation of spin-diffusion effects from other protons belonging either to the cofactor or to the binding pocket of the enzyme. The analysis indicates that the structure of bound NAD+ is in accord with the conformation determined in the solid state by x-ray diffraction for the adenosine moiety, but deviates significantly from that of the nicotinamide. The NMR data indicate conformational averaging about the glycosidic bond of the nicotinamide nucleotide. In view of the strict stereospecificity of catalysis by LDH and the conformational averaging of bound NAD+ that we infer from solution-state NMR, we suggest that LDH binds the cofactor in both syn and anti conformations, but that binding interactions in the syn conformation are not catalytically productive.
Effect of High Salt Concentration on Ion Clustering and Transport in Polymer Solid Electrolytes: a Molecular Dynamics Study of PEO-LiTFSI (2018)

&lt;div&gt; &lt;div&gt; &lt;div&gt; &lt;p&gt;The model and analysis methods developed in this work are generally applicable to any polymer electrolyte/cation-anion combination, but we focus on the currently most prominent polymer electrolyte material system: poly(ethylene) oxide/Li- bis(trifluoromethane) sulfonamide (PEO + LiTFSI). The obtained results are surprising and challenge the conventional understanding of ionic transport in polymer electrolytes: the investigation of a technologically relevant salt concentration range (1 - 4 M) revealed the central role of the anion in coordinating and hindering Li ion movement. Our results provide insights into correlated ion dynamics, at the same time enabling rational design of better PEO-based electrolytes. In particular, we report the following novel observations. 1. Strong binding of the Li cation with the polymer competes with significant correlation of the cation with the salt anion. 2. The appearance of cation-anion clusters, especially at high concentration. 3. The asymmetry in the composition (and therefore charge) of such clusters; specifically, we find the tendency for clusters to have a higher number of anions than cations.&lt;/p&gt; &lt;/div&gt; &lt;/div&gt; &lt;/div&gt;
Record wide tunable top-emitting VCSELs for LAN applications (2002)

We report a top-emitting, micromechanical VCSEL with 30.8 nm of tuning, the widest continuous tuning range demonstrated by a VCSEL to date. Over the entire tuning range, I/sub th/ remains 1.2 mA-3.4 mA and P/sub out/ in the mW range.
Starvation Time and Successive Collection Effects on Leeches Saliva Collection Quantity and Proteins Quality and Quantity in Wet Season (Kesan Masa Kebuluran dan Kejayaan Pengumpulan Kuantiti Air Liur Lintah serta Kualiti dan Kuantiti Protein dalam Musim Hujan) (2014)

The salivary gland secretion of the haematophagous animals, leeches, has attracted the attention of therapists since the extreme old ages due to its wide range of medical properties. Thus, many researches have been done to develop and optimize new methods to collect leech saliva with high quality and quantity. In the present study, we aimed to evaluate the effects of starvation period and repeated collection on the quality and quantity of leech saliva extract LSE and its contents of proteins during the rainy season. Protein recovery in the LSE was also studied after first collection. It was found that leeches are able to produce protein-containing saliva whenever fed during the whole study period of 18 weeks with varied protein concentrations. The results showed that the highest protein concentrations (105-91 μ g/mL ) were produced after 12-15 weeks of starvation. The results of successive collection showed that leeches are able to produce proteins and peptides whenever they suck the solution after first collection with some varies in the concentrations. The concentrations varied between 0 and 72% of the initial concentration. Gel electrophoresis results showed absence for some bands when the concentrations are too low. Also the results showed that leeches are able to recover about 42% of their initial proteins concentration within four weeks of starvation after first feeding. The gel electrophoresis results showed the closeness between the first and second collections. To conclude, all test factors (starvation period, successive collection and recovery test) were shown to have an important impact on protein concentration of leech saliva and therefore its medicinal affectivity. The mentioned results are reported for the first time and they open the gate for further studies.
An overview of Trilinos. (2003)

The Trilinos Project is an effort to facilitate the design, development, integration and ongoing support of mathematical software libraries. In particular, our goal is to develop parallel solver algorithms and libraries within an object-oriented software framework for the solution of large-scale, complex multi-physics engineering and scientific applications. Our emphasis is on developing robust, scalable algorithms in a software framework, using abstract interfaces for flexible interoperability of components while providing a full-featured set of concrete classes that implement all abstract interfaces. Trilinos uses a two-level software structure designed around collections of packages. A Trilinos package is an integral unit usually developed by a small team of experts in a particular algorithms area such as algebraic preconditioners, nonlinear solvers, etc. Packages exist underneath the Trilinos top level, which provides a common look-and-feel, including configuration, documentation, licensing, and bug-tracking. Trilinos packages are primarily written in C++, but provide some C and Fortran user interface support. We provide an open architecture that allows easy integration with other solver packages and we deliver our software to the outside community via the Gnu Lesser General Public License (LGPL). This report provides an overview of Trilinos, discussing the objectives, history, current development and future plans of the project.

Extraction of carrier lifetime in Ge waveguides using pump probe spectroscopy (2016)

Carrier lifetimes in Ge-on-Si waveguides are deduced using time-resolved infrared transmission pump-probe spectroscopy. Dynamics of pump-induced excess carriers generated in waveguides with varying Ge thickness and width is probed using a CW laser. The lifetimes of these excess carriers strongly depend on the thickness and width of the waveguide due to defect assisted surface recombination. Interface recombination velocities of 0.975 × 104 cm/s and 1.45 × 104 cm/s were extracted for the Ge/Si and the Ge/SiO2 interfaces, respectively.
A dysregulated bile acid-gut microbiota axis contributes to obesity susceptibility (2020)

On the Opportunities and Challenges of NOMA-Based Fog Radio Access Networks: An Overview (2020)

Future generations of wireless networks are expected to provide new services with an unprecedented level of diverse and stringent requirements. Fog Radio Access Network (FRAN) and Non-Orthogonal Multiple Access (NOMA) have emerged as complimentary enablers to meet such requirements. On the one hand, FRAN architecture is designed to reduce the delay caused by the fronthaul link by pushing control and storage to the network edge. On the other hand, in addition to increasing the spectral and energy efficiency and the number of connected devices, NOMA has the potential to improve network latency. This paper overviews the joint benefits of enabling NOMA schemes in an FRAN architecture, by means of examining the applicability and adequateness of the NOMA-based FRAN features in achieving specific objectives of next generation of mobile networks, mainly those related to enhanced mobile broadband (eMBB), massive machine type communications (mMTC), and ultra-reliable low latency communication (URLLC). The paper further depicts the challenges and future research directions that must be addressed in order to meet such opportunities.

First Measurement of Differential Charged Current Quasielasticlike νμ-Argon Scattering Cross Sections with the MicroBooNE Detector (2020)

We report on the first measurement of flux-integrated single differential cross sections for charged-current (CC) muon neutrino (ν_{μ}) scattering on argon with a muon and a proton in the final state, ^{40}Ar (ν_{μ},μp)X. The measurement was carried out using the Booster Neutrino Beam at Fermi National Accelerator Laboratory and the MicroBooNE liquid argon time projection chamber detector with an exposure of 4.59×10^{19} protons on target. Events are selected to enhance the contribution of CC quasielastic (CCQE) interactions. The data are reported in terms of a total cross section as well as single differential cross sections in final state muon and proton kinematics. We measure the integrated per-nucleus CCQE-like cross section (i.e., for interactions leading to a muon, one proton, and no pions above detection threshold) of (4.93±0.76_{stat}±1.29_{sys})×10^{-38} cm^{2}, in good agreement with theoretical calculations. The single differential cross sections are also in overall good agreement with theoretical predictions, except at very forward muon scattering angles that correspond to low-momentum-transfer events.
Trade-off of dispersion slope and effective area in Ultra Low Slope NZ-DSF for non-dispersion-compensated WDM metro transmission (2005)

We investigate the nonlinear penalty of ultra-low-slope NZ-DSF with less than 50-/spl mu/m/sup 2/ effective area in nondispersion-compensated systems. For 80and 155-km, 10-Gbit/s transmission, negligible nonlinear penalty was found for launch powers up to 0 dBm/ch.

In vivo evidence that inhibin is a gonadotropin surge- inhibiting/attenuating factor (1992)

Hyperstimulation of ovarian function through exogenous gonadotropin administration suppresses the preovulatory surges of both LH and FSH. This phenomenon has been demonstrated to be the result of a non-steroidal factor released from the ovary that has been designated as either gonadotropin surge-inhibiting factor or attenuating factor (GnSIF/AF). To examine the possibility that inhibin might possess the activity ascribed to this factor, endogenous inhibin was immunoneutralized in female rats under conditions known to stimulate GnSIF/AF activity. Inhibin-like immunoreactivity was found to be significantly elevated in FSH-treated rats prior to the time of the gonadotropin surges. Spontaneous preovulatory surges of both LH and FSH were observed in saline-treated (control) rats that were subsequently treated with either anti-inhibin serum (AS) or normal sheep serum (NS). FSH-treatment completely prevented the occurrence of gonadotropin surges in rats subsequently treated with NS. In FSH-injected rats subsequently treated with AS, however, normal preovulatory surges of both LH and FSH were observed. These results indicate that inhibin may be the factor responsible for the suppression of the preovulatory gonadotropin surges in FSH-treated rats and, at least in this species, may be a GnSIF/AF.
