Multicolored light emitters on silicon substrates (1998)

We demonstrate the operation of multicolored light emitting diodes (LEDs) on a silicon wafer using ultraviolet/violet GaN LEDs grown by molecular beam epitaxy on Si(111) in conjunction with organic dye based color converters. These organic converters, applied on top of the nitride diodes, absorb the nitride LED electroluminescence at ∼360 nm, and fluoresce in the green (∼530 nm), and orange (∼600 nm). In this fashion, multicolored light emitters may be made to operate side by side and monolithically on the same Si wafer in an approach that may be attractive for miniature GaN based full color displays.
Distribution Locational Marginal Pricing (DLMP) for Multiphase Systems (2018)

With the rise of various distributed energy resources into the distribution networks, an electricity market, similar to that of the transmission level, is foreseen to evolve in the near future, aiming to indulge and financially encourage the private resources to participate in the balance and resiliency of the system. This paper adopts the locational marginal pricing, a well-known scheme to quantify nodal pricing, and analyzes the signals sent to future-market participants to meet the demand, reduce losses, and alleviate congestion. The DLMPs derived in this paper are based on an AC OPF, convexified using semidefinite programming (SDP) relaxation, which accounts for structural characteristics of the distribution networks. Thorough case studies with a multi-period optimization are performed on the IEEE 37-bus feeder with the inclusion of distributed generators and a static-Var compensator. The unbalanced nature of distribution loads and lines induces disparate DLMPs at each phase. The analysis also contrasts passive and active distribution networks giving more emphasis to the contribution and incentives of the latter. The active networks show increased penetrations of end-users' renewable supply are interpreted as the shadow prices that reflect on the reduction of the entire consumer payment.
Chemical cross-linking of Chlamydia trachomatis (1988)

Purified elementary bodies (EBs) of Chlamydia trachomatis serovar L2 were analyzed by chemical cross-linking with disuccinimidyl selenodipropionate. The effect of the cross-linking was analyzed by immunoblotting sodium dodecyl sulfate-polyacrylamide gel electrophoresis-separated components which were reacted with monoclonal antibodies against major outer membrane protein (MOMP) and lipopolysaccharide (LPS). It was shown that in EBs, MOMP was cross-linked to the LPS component of the outer membrane. Migration analysis of the cross-linked components showed that with extensive cross-linking, most of the MOMP became cross-linked to LPS, changing the migration rate from 40 to 42.5 kilodaltons. A small fraction of MOMP associated with LPS was shown to be present in bands with migration rates of 100 and 110 kilodaltons. No association of MOMP or LPS to other proteins, or to dimer or multimer forms of MOMP without LPS, was observed. A totally different membrane structure must be present in reticulate bodies, since there, MOMP was so heavily cross-linked that it did not enter the polyacrylamide gel and thus became impossible to analyze. Furthermore, the monoclonal antibody, which reacted with LPS associated with MOMP in the cross-linked EBs, did not react with reticulate bodies.

Crystal structure of carboxypeptidase T from <i>Thermoactinomyces vulgaris</i> (1992)

The crystal structure of carboxypeptidase T from Thermoactinomyces vulgaris has been determined at 0.235-nm resolution by X-ray diffraction. Carboxypeptidase T is a remote homologue of mammalian Zn-carboxypeptidases. In spite of the low degree of amino acid sequence identity, the three-dimensional structure of carboxypeptidase T is very similar to that of pancreatic carboxypeptidases A and B. The core of the protein molecule is formed by an eight-stranded mixed beta sheet. The active site is located at the C-edge of the central (parallel) part of the beta sheet. The structural organization of the active centre appears to be essentially the same in the three carboxypeptidases. Amino acid residues directly involved in catalysis and binding of the C-terminal carboxyl of a substrate are strictly conserved. This suggests that the catalytic mechanism proposed for the pancreatic enzymes is applicable to carboxypeptidase T and to the whole family of Zn-carboxypeptidases. Comparison of the amino acid replacements at the primary specificity pocket of carboxypeptidases A, B and T provides an explanation of the unusual 'A+B' type of specificity of carboxypeptidase T. Four calcium-binding sites localized in the crystal structure of carboxypeptidase T could account for the high thermostability of the protein.
An Improved Model of Rough Sets on Incomplete Information Systems (2009)

According to rough set theory, there are two approaches used to handle incomplete information systems. One is to transfer the incomplete information systems into complete information systems that can be tackled by the classical rough set theory. The other is to deal directly with the incomplete information systems through improving the classical rough set theory. But basically the first approach will change what the original incomplete information systems implicate. Therefore, the better approach is to utilize the second one. In this paper, the second approach is discussed. Through an analysis to the limited tolerance relation on incomplete information systems, the concept of "similarity degree" is introduced for improving the limited tolerance relation into a new model named after the limited tolerance relation based on similarity degree. The new model is more flexible on processing incomplete information systems than the limited tolerance relation is.

Least-Squares Based Layerwise Pruning Of Convolutional Neural Networks (2018)

In this paper, we propose a new layerwise pruning method to reduce the number of computations needed to evaluate convolutional neural networks (CNN) after training. This least-squares (LS) based pruning method improves state-of-the-art pruning methods as it solves both problems, how to select the feature maps to be pruned and how to adapt the remaining parameters in the kernel tensor to compensate the introduced pruning errors, jointly. Therefore, our method utilizes both correlations between the input feature maps and the structure in the kernel tensor. In experiments, we show that high reduction rates with a small performance degradation can be obtained with our pruning method and that our pruning method performs significantly better than low-rank factorization methods.
The role of aldosterone and aldosterone-receptor antagonists in heart failure. (2004)

Prolonged overactivation of neurohormonal mechanisms in heart failure produces deleterious effects on the cardiovascular system and leads to poor prognosis. Angiotensin-converting enzyme (ACE) inhibitors and beta-blockers have been shown to interrupt this excessive overactivity and improve survival. Activation of the renin-angiotensin system leads to increased synthesis of aldosterone in heart failure. Some aldosterone production is independent of ACEs; therefore, ACE inhibition does not entirely suppress the excessive formation of aldosterone. An excess of aldosterone in heart failure leads to sodium retention and myocardial fibrosis. The use of aldosterone antagonists, combined with standard therapy for heart failure, improves morbidity and mortality.
The prevention of glomerulosclerosis in rats using traditional Chinese medicine, Sairei‐to (2000)

SUMMARY: The effects of Sairei‐to on chronic irreversible lesions were examined by the administration of drugs after the initiation of irreversible renal lesions by uninephrectomy and anti‐thy‐1 antibody injection. Twenty‐one female Wistar rats were divided into three groups. Group 1 was treated with phosphate‐buffered saline (PBS) as a control and groups 2 and 3 were treated with Sairei‐to 400 mg/kg bodyweight per day on a daily basis beginning on day 1 (group 2) and day 7 (group 3) to day 42 after the intravenous administration of 500 μg anti‐thy‐1 monoclonal antibody (MoAb) into uninephrectomized rats, respectively. Statistically significant effects of Sairei‐to on proteinuria were observed on days 3, 7, 14, and 21 in group 2 and on day 21 in group 3 as compared with the PBS controls. On day 42, light microscopy showed that Sairei‐to ameliorated morphological lesions (Matrix score: 133.7 ± 50.35 for group 1 vs 40.0 ± 24.0 for group 2, P < 0.05). The weight of the kidneys in groups given Sairei‐to was also lower than that in the PBS control. In addition, immunofluorescent findings showed that Sairei‐to suppressed the expression of transforming growth factor‐beta (TGF‐β), alpha‐smooth muscle actin (α‐SMA) and collagen type I in glomeruli and decreased the number of ED1‐ and OX8‐positive cells in tubulo‐interstitium as well as in glomeruli. In conclusion, Sairei‐to blocked the progression of renal lesions in this model even when it was administered after the initiation of the disease. In addition, earlier treatment more effectively prevented the progression of the renal lesions.

Antibacterial activity of dental composites containing zinc oxide nanoparticles (2010)

The resin-based dental composites commonly used in restorations result in more plaque accumulation than other materials. Bacterial biofilm growth contributes to secondary caries and failure of resin-based dental composites. Methods to inhibit biofilm growth on dental composites have been sought for several decades. It is demonstrated here that zinc oxide nanoparticles (ZnO-NPs) blended at 10% (w/w) fraction into dental composites display antimicrobial activity and reduce growth of bacterial biofilms by roughly 80% for a single-species model dental biofilm. Antibacterial effectiveness of ZnO-NPs was assessed against Streptococcus sobrinus ATCC 27352 grown both planktonically and as biofilms on composites. Direct contact inhibition was observed by scanning electron microscopy and confocal laser scanning microscopy while biofilm formation was quantified by viable counts. An 80% reduction in bacterial counts was observed with 10% ZnO-NP-containing composites compared with their unmodified counterpart, indicating a statistically significant suppression of biofilm growth. Although, 20% of the bacterial population survived and could form a biofilm layer again, 10% ZnO-NP-containing composites maintained at least some inhibitory activity even after the third generation of biofilm growth. Microscopy demonstrated continuous biofilm formation for unmodified composites after 1-day growth, but only sparsely distributed biofilms formed on 10% ZnO-NP-containing composites. The minimum inhibitory concentration of ZnO-NPs suspended in S. sobrinus planktonic culture was 50 microg mL(-1). ZnO-NP-containing composites (10%) qualitatively showed less biofilm after 1-day-anaerobic growth of a three-species initial colonizer biofilm after being compared with unmodified composites, but did not significantly reduce growth after 3 days.
Vasoactive intestinal polypeptide (VIP) and peptide histidine methionine (PHM) in human penile corpus cavernosum tissue and circumflex veins: localization and <i>in vitro</i> effects (1992)

Localization and functional effects of vasoactive intestinal polypeptide (VIP) and peptide histidine methionine (PHM), two peptides derived from a common precursor molecule, were investigated in isolated preparations from human penile corpus cavernosum (CC) and circumflex vein (CV). VIP- and PHM-immunoreactivity (IR) was demonstrated in both CC and CV. The concentrations of VIP-IR and PHM-IR in CC tissue were 54.4 +/- 15.3, and 42.0 +/- 7.5 pmol g-1 wet weight respectively with a VIP/PHM ratio of 1.5 +/- 0.4 (mean +/- SEM). The corresponding values for CV tissues were 28.0 +/- 7.7 and 9.6 +/- 2.6 pmol g-1 wet weight with a VIP/PHM ratio of 3.1 +/- 0.4. CC and CV displayed VIP- and PHM-IR confined to nerve fibres in close relation to bundles of smooth muscle cells and blood vessels in both tissues. In vitro, VIP and PHM had no effects in unstimulated tissue preparations. Both peptides concentration-dependently (10(-9)-10(-6) M) relaxed CC and CV preparations precontracted with 3 x 10(-6) M noradrenaline. In CC the maximum relaxant effect of VIP and PHM was 22 +/- 11% and 9 +/- 9% and in CV the corresponding values were 82 +/- 8% and 93 +/- 3% respectively. The present study supports the hypothesis of VIP and PHM as neurotransmitters and/or neuromodulators in the nervous control of penile erection.
Design and optical characterization of photonic crystal lasers with organic gain material (2010)

We present a design concept for an optimized surface-emitting laser with two-dimensional feedback structure and organic gain material. The basic laser structure consists of an array of holes within a thin film of Ta2O5. The optical properties of such feedback structures are investigated theoretically and experimentally. Combining first-order with second-order photonic structures leads to a higher quality factor of the feedback structure, resulting in a lower laser threshold and/or a much smaller footprint of the laser.
Atomic Norm Minimization for Modal Analysis From Random and Compressed Samples (2018)

Modal analysis is the process of estimating a system's modal parameters, such as its natural frequencies and mode shapes. One application of modal analysis is in structural health monitoring (SHM), where a network of sensors may be used to collect vibration data from a physical structure, such as a building or bridge. There is a growing interest in developing automated techniques for SHM based on data collected in a wireless sensor network. In order to conserve power and extend battery life, however, it is desirable to minimize the amount of data that must be collected and transmitted in such a sensor network. In this paper, we highlight the fact that modal analysis can be formulated as an atomic norm minimization (ANM) problem, which can be solved efficiently and in some cases recover perfectly a structure's mode shapes and frequencies. We survey a broad class of sampling and compression strategies that one might consider in a physical sensor network, and we provide bounds on the sample complexity of these compressive schemes in order to recover a structure's mode shapes and frequencies via ANM. A main contribution of our paper is to establish a bound on the sample complexity of modal analysis with random temporal compression, and in this scenario we prove that the required number of samples per sensor can actually decrease as the number of sensors increases. We also extend an atomic norm denoising problem to the multiple measurement vector setting in the case of uniform sampling.
Involvement of complement components in renal disease (1997)

The complement system is a critical element of innate immunity whose role in renal physiology and disease is illustrated by the following observations: (1) a deficiency or inhibition of a complement regulatory protein results in renal tissue damage; (2) inhibition of complement activation (with cobra venom factor or sCR1), or in C6-deficient rats, attenuates complement-mediated tissue destruction; and (3) ongoing glomerular disease has been associated with the deposition/expression of complement proteins in glomerular or tubular structures and the excretion of C5b-9 and CD59 proteins. Complement activation by cellulosic membranes results in the production of C5a, which has now been shown to provoke most of the same inflammatory responses observed during hemodialysis. Controlling the dose of C5a given during dialysis, by controlling blood flow rates or membrane types, may have an impact on patient health. Finally, lessons learned in the xenotransplant setting suggest that complement activation can be effectively controlled to limit inflammation (with sCR1 or anti-C5 monoclonal antibodies). Recent developments in this area may lead to new therapeutic approaches to deal with the complex etiology of renal disease.
Assessment of the AAAI USAR Robotics Competition. (2002)

• Lighting is never ideal in a disaster site. In order to simulate realistic lighting, drape the arena in a shade cloth (mounted high enough to block the overhead lighting but out of the way of spectators) then add in emergency lighting throughout the course. This way, the audience can still view the course during competition and competitors get a better feel for the odd lighting encountered during a disaster. • Rescue teams most often enter the hot zone of a disaster site from the easiest and safest point of entry (the area with the least damage). The environment gets progressively more demolished/difficult as the team moves through it. The competition arena should also reflect this realism by uniting the three course sections into one. And have the entry point stationed at the easiest area. Multiple entry points will still need to be provided for purposes of judging and video taping. This will also keep the teams from going for easy high points, while not actually entering the difficult areas. • Sheets (large slabs) of concrete are commonly found in a disaster site. Sheets of painted Styrofoam can be used to simulate concrete sheets. This would add to the realism of the course. • A “Pass” device is specifically for a downed fireman. A looped tape of this device is not the best choice especially if firemen are present.
The Secreted Product of <b> <i>Xenopus</i> </b> Gene <b> <i>lunatic Fringe</i> </b> , a Vertebrate Signaling Molecule (1996)

Signaling molecules are essential for vertebrate embryonic development. Here, two Xenopus homologs of the Drosophila gene fringe, lunatic Fringe (lFng) and radical Fringe (rFng), were identified and the protein product of lFng further characterized. The messenger RNA of lFng is supplied as a maternal message. Its product is a precursor protein consisting of pre-, pro-, and mature regions. The mature lunatic Fringe protein is secreted extracellularly, and it induced mesodermal tissue formation in animal cap assays. These results indicate that secreted lunatic Fringe can induce mesoderm and reveal that the Fringe proteins are a family of vertebrate signaling molecules.
Addition of integrin binding sequence to a mutant human endostatin improves inhibition of tumor growth (2004)

Tumor vasculatures express high levels of alphaVbeta3/alphaVbeta5 and alpha5beta1 integrins. Consequently, peptides containing the RGD (Arg-Gly-Asp) sequence, which is present in ligands of integrins, is effective in targeting therapeutic reagents to tumor vascular endothelium. In our study, we investigated whether the biologic activity of endostatin can be enhanced by the addition of an integrin targeting sequence. RGD sequence was added to either the amino or carboxyl terminus of endostatin containing a point mutation, P125A-endostatin. Earlier we have shown that the P125A mutation did not affect the biologic activity of endostatin but in fact had better antiangiogenic activity when compared to the native molecule. Further modification of P125A-endostatin with the RGD motif showed specific and increased binding to endothelial cells, and the increased binding coincided with improved antiangiogenic properties. Both amino and carboxyl terminal RGD-modification of P125A-endostatin resulted in greater inhibition of endothelial cell migration and proliferation. RGD modification increased tumor localization without affecting the circulatory half-life of P125A-endostatin, and RGD-modified P125A-endostatin was found to be more effective when compared to the P125A-endostatin in inhibiting ovarian and colon cancer growth in athymic mice. Complete inhibition of ovarian tumor growth was observed when P125A-endostatin-RGD was encapsulated into alginate beads. These studies demonstrate that addition of a vascular targeting sequence can enhance the biologic activity of an antiangiogenic molecule.
Agrobacterium tumefaciens possesses a fourth flagellin gene located in a large gene cluster concerned with flagellar structure, assembly and motility (1999)

The authors have identified a fourth flagellin gene in a 21850 bp region of the Agrobacterium tumefaciens C58C1 chromosome containing at least 20 genes concerned with flagellar structure, assembly and function. Three flagellin genes, flaA, flaB and flaC, orientated rightward, are positioned in a tandem array at the right end, with the fourth, substantially larger gene, flaD, in the opposite orientation, at the left end. Between these lie four apparent operons, two transcribed in each direction (motA, flhB leftward; flgF, flgB rightward) from a divergent position approx 7.5 kb from the left end. This unifies the previously published motA, flgB and flaABC sequences into a single region, also containing the homologues of flhB, flgF and fliI. Site-specific mutagenesis of fliI results in a non-flagellate phenotype, while a Tn5-induced flhB mutant possesses abnormal flagella. Mutagenesis and protein profiling demonstrate that all four flagellins contribute to flagellar structure: FlaA is the major protein, FlaB and FlaC are present in lesser amounts, and FlaD is a minor component. FlaA has anomolous electrophoretic mobility, possibly due to glycosylation.
