Weak Contrast PP Wave Displacement R/T Coefficients in Weakly Anisotropic Elastic Media (1998)

Approximate PP plane wave displacement coefficients of reflection and transmission for weak contrast interfaces separating weakly but arbitrarily anisotropic elastic media are presented. The PP reflection coefficient for such an interface has been derived recently by Vavryčuk and Pšenčík (1997). The PP transmission coefficient presented in this paper was derived by the same approach. The coefficients are given as a sum of the coefficient for the weak contrast interface separating two nearby isotropic media and a term depending linearly on contrasts of the so-called weak anisotropy (WA) parameters (parameters specifying deviation of properties of the medium from isotropy), across the interface. While the reflection coefficient depends only on 8 of the complete set of the WA parameters describing P-wave phase velocity in weakly anisotropic media, the transmission coefficient depends on their complete set. The PP reflection coefficient depends on “shear-wave splitting parameter” γ. Tests of accuracy of the approximate formulae are presented on several models.
Probing galaxy evolution with the optical/UV monitor on XMM (1997)

The Optical Monitor is one of the three instruments on XMM, the X-ray Multi-Mirror Mission, scheduled to launch in August of 1999. The Optical Monitor is a 30 cm telescope system that will image in 7 bands from 1500 Å to 6000 Å, with a resolution of 1 arcsecond. Two grisms are available for low-dispersion spectral discrimination. The Optical Monitor will be coaligned with the X-ray instruments and the expected long integrations will allow detection of point sources as faint as 24th magnitude. Over the course of the XMM mission, a large database of galaxy observations, both targeted and serendiptous, will be assembled, covering far-ultraviolet through optical wavelengths. We indicate here ways in which these observations will be used to study galaxy evolution.
64 Behind every healthy man, there's a woman: A qualitative inquiry (2011)

during the short-term follow-up, with 6 cystic fat nodules. The satisfaction rate for sexual function, morphology and global state were 79.8%, 78.9%, and 91.7%. Conclusions: Our technique shows very effective shortterm outcomes and patient’s satisfaction without serious complications. 62 A case of 47,XXY/46,XY Klinefelter syndrome H. Masuda1, Y. Katsuoka2. 1Aino Hospital, 2 Osaka Medical College, Japan Klinefelter syndrome represents the most commonly found human sex chromosomal abnormality. It is characterized by small, firm testes with hyalinization of the seminiferous tubules, elevated gonadotropins and azoospermia. Males with Klinefelter syndrome may have a 47,XXY or a mosaic 47,XXY/46,XY constitutional karyotype and varying degrees of spermatogenic failure. Mosaicism 47,XXY/46,XX with clinical features suggestive of Klinefelter syndrome is very rare. We report here a case of a mosaic 47,XXY/46,XX infertile male. The patient was a 31-year-old male. Physical examination revealed perfect male-type of genitalia, almost normal penis and bilateral small testicles, being 1.0 × 2.0 × 1.0 cm sized for the right and 1.0 × 2.0 × 1.0 cm for the left. Chromosome analysis by means of culture of peripheral blood lymphocytes revealed twokinds of 46 chromosomes and of 47 chromosomes. The genotype of the former was XX and of the later was XXY, making XX/XXY mosaicism. Testicular sperm extraction was performed, but we could find the sperm in microdissection testicular sperm extraction procedure. Histologically the testicle showed atrophy of seminiferous tubules with hyalinizaition of the canaliculi. No spermatogenesis was observed at all. 63 Coenzyme Q10 treatment for oligoasthenoteratozoospemia in infertile men with varicocele Y. Kobori, H. Okada, G. Arai, S. Soh, H. Yagi. Dokkyo Medical University Koshigaya Hospital, Department of Urology, Japan Objective: To evaluate the effectiveness of coenzyme Q10 treatment in improving semen quality in men who have varicocele with infertility. Patients: Sixty-nine infertile patients (21–51 years of age) with the following baseline sperm selection criteria: concentration 30%. Patients underwent therapy with coenzyme Q10, 30mg/day. We investigated seminograms, background, hormonal analyses. We also investigated the modern ART used to overcome sterility. Results: Coenzyme Q10 and ubiquinol increased significantly sperm concentration, aswell as spermatozoa motility. Intracytoplasmic sperm injection (ICSI) was performed 2 patients, varicocelectomy was performed 1 patient, and total 10 patients are resulted pregnancy. Conclusions:The exogenous administration of coenzyme Q10 increases the level of the same and ubiquinol in semen and is effective in improving sperm kinetic features in patients affected by idiopathic asthenozoospermia with valicocele.
Annealing Time Effect Fluctuation Induced Excess Conductivity in Bi (Pb):2223 Superconductors (2013)

We report here on the effect of annealing time, in air and at 800°C for time periods of (6-30 h), on the fluctuation induced excess conductivity ∆σ in Bi2-xPbx: 2223 superconductors with various x values. The logarithmic plots of ∆σ and the reduced temperature e reveal three different exponents corresponding to two different crossover temperatures in the slope of each plot. The first exponent in the normal region is at a temperature of (Tc^(mf) ＜＜ T ＜ 2Tc ^(mf) ) and its values are close 2.5, in which the order parameter dimensionality (OPD) is not 0D. The second exponent is at a temperature of T ＞ Tc^(mf) , and its values are close to 1, in which the OPD is 2D. The third exponent is in the critical-field region at a temperature of (Tc ＜ T ≤ Tc^(mf)), and its values are close to 0.5, in which the OPD is 3D. Furthermore, the interlayer coupling J, Ginzburg-Landau coherence length ζc(0), temperature width (To-T^c(mf)), and resistivity slope (dp/dT) are also calculated for the two examined samples, and their values are affected by changing both the annealing time and Pb content. Our results are discussed in terms of the correlation between the carrier concentration and volume fraction of the high Tc phase for the considered samples.
Kinetics of Hydride Transfer from Metal-Free Hydride Donors to CO2 (2020)

Selective reduction of CO&lt;sub&gt;2&lt;/sub&gt; to formate represents an ongoing challenge in photoelectrocatalysis. To provide mechanistic insights, we investigate the kinetics of hydride transfer (HT) from a series of metal-free hydride donors to CO&lt;sub&gt;2&lt;/sub&gt;. The observed dependence of experimental and calculated HT barriers on the thermodynamic driving force was modeled using the Marcus hydride transfer formalism to obtain the insights into the effect of reorganization energies on the reaction kinetics. Our results indicate that, even if the most ideal hydride donor were discovered, the HT to CO&lt;sub&gt;2&lt;/sub&gt; would exhibit sluggish kinetics (less than 100 turnovers at 0.1 eV driving force), indicating that the conventional HT may not be an appropriate mechanism for Solar conversion of CO&lt;sub&gt;2&lt;/sub&gt; to formate. We propose that the conventional HT mechanism should not be considered for CO&lt;sub&gt;2&lt;/sub&gt; reduction catalysis and argue that the orthogonal HT mechanism, previously proposed to address thermodynamic limitations of this reaction, may also lead to lower kinetic barriers for CO&lt;sub&gt;2&lt;/sub&gt; reduction to formate.
Amino acid‐derived Poly(L‐Lysine) (p(LL)) microgel as a versatile biomaterial: Hydrolytically degradable, drug carrying, chemically modifiable and antimicrobial material (2020)

Here, a microgel of poly( L ‐Lysine) (p(LL)) from an amino acid, L ‐Lysine, was synthesized by microemulsion technique using AOT as surfactant in gasoline. The prepared p(LL) microgel was shown to be hydrolytically degradable at pH values of 5.4, 7.4, and 9 in phosphate buffer solution (PBS). The protonated p(LL) microgel was loaded with model drugs such as naproxen and riboflavin and found to release about 80% of loaded naproxen in 180 minutes and 70% of loaded riboflavin in about 120 minutes suggesting the potential of p(LL) microgels to act as fast drug delivery vehicles. Furthermore, p(LL) microgels were chemically modified with 1‐bromoethane (BE), 1‐bromooctane (BO), and 1‐bromoethylamine (BEA) to render antimicrobial capabilities. It was found that protonated p(LL) microgels had 29 ± 1 mm inhibition zone diameter for Pseudomonas aeruginosa ATCC 10145. Furthermore, minimum inhibition concentration (MIC) and minimum bactericidal concentration (MBC) values for Staphylococcus aureus ATCC 6538 were also calculated as 1 and 2.5 mg/mL concentrations, respectively, for protonated p(LL) microgels.

Inhibition of Growth, Nodulation, and Nitrogen Fixation of Legumes by Quackgrass1 (1985)

Quackgrass ( Agropyron repens L. Beauv.) has been previously reported to possess allelopathic potential. Both the shoots and rhizomes of quackgrass have been shown to contain inhibitors of seed germination and crop growth. We recently observed chlorosis and decreases in nodulation in snapbeans that were planted into quackgrass infested sites. The objective of this study was to determine if nodulation, N, 2 fixation and legume growth were inhibited in the presence of living or herbicidally treated quackgrass. Soybeans ( Glycine max L. Merr.) and navybeans and snapbeans ( Phaseolus vulgarls L.) were grown both in greenhouse and field experiments in living or killed quackgrass. Inoculated legumes were seeded in the following regimes: 1) living quackgrass sod which was regularly mowed; 2) glyphosate [N‐(phosphonomethyl) glycine] ‐treated quackgrass sod 3) soil from quackgrass sod from which plant material was removed by sieving or raking; 4) a control soil of similar type and physical structure free from quackgrass infestation. Nodulation and plant growth were measured by recording nodule number and fresh weight and root and shoot weights before flowering. Nitrogen fixation was estimated by the acetylene reduction assay. Legumes grown in mowed quackgrass sod in the greenhouse and in the field exhibited decreased nodule number, nodule fresh weight and N, fixation when compared to legumes grown under similar conditions in screened quackgrass soil or the control soil. Shoot and root weights were also significantly decreased in field and greenhouse experiments when legumes were grown in living quackgrassod. In many cases, legume nodulation and growth were decreased in glyphosate‐treated quackgrassod as compared to screened quackgrass soil or the control soil. Decreases in legume growth and nodulation in the presence of quackgrass may be attributed to allelochemical effects.
OX40-OX40L interactions: a promising therapeutic target for allergic diseases? (2007)

Recent advances in understanding the cellular and molecular mechanisms of atopy have shed light on potential targets for the development of new therapies for allergic diseases. In this issue of the JCI, Seshasayee et al. provide direct in vivo evidence that OX40 has critical roles in allergic inflammation mediated by thymic stromal lymphopoietin (TSLP) (see the related article beginning on page 3868). Blockade of interactions between OX40 on Th2 cells and OX40 ligand (OX40L) on TSLP-activated DCs using an OX40L-specific monoclonal antibody, inhibited Th2 cell-mediated immune responses in both mouse and nonhuman primate models of allergic inflammation. The results point to potential therapeutic approaches to targeting the cellular and molecular mechanism underlying TSLP-mediated allergic inflammation.
Similarity analysis of legal judgments (2011)

In this paper, we have made an effort to propose approaches to find similar legal judgements by extending the popular techniques used in information retrieval and search engines. Legal judgements are complex in nature and refer other judgements. We have analyzed all-term, legal-term, co-citation and bibliographic coupling-based similarity methods to find similar judgements. The experimental results show that the legal-term cosine similarity method performs better than all-term cosine similarity method. Also, the results show that bibliographic coupling similarity method improves the performance over co-citation approach.

TGF-β1 Inhibits T-bet Induction by IFN-γ in Murine CD4+ T Cells through the Protein Tyrosine Phosphatase Src Homology Region 2 Domain-Containing Phosphatase-1 (2005)

TGF-beta1 prevents the development of autoimmune disease by restraining the development of autoreactive Th1 cells. TGF-beta1 inhibits Th1 development in part by suppressing the expression of T-bet, an IFN-gamma-induced transcription factor that promotes Th1 differentiation, but how TGF-beta1 suppresses T-bet is not known. In this study we show that TGF-beta1 suppresses IFN-gamma-induced T-bet expression through the hemopoietic protein tyrosine phosphatase (PTP) Src homology region 2 domain-containing phosphatase-1 (Shp-1). In murine CD4+ T cells, IFN-gamma rapidly induced the expression of T-bet as well as of IFN regulatory factor-1, another transcription factor important for Th1 development. TGF-beta1 antagonized the effects of IFN-gamma, inhibiting IFN-gamma's induction of both Th1 transcription factors. In the presence of IFN-gamma, TGF-beta1 rapidly induced in Th cells the synthesis of the PTP Shp-1, but did not induce Shp-2 or several members of the suppressor of cytokine signaling family of Jak-Stat inhibitors. We tested the requirement for Shp-1 by using T cells from the Shp-1-deficient me(v)/me(v) mouse strain. Shp-1 was required for TGF-beta1's suppressive effects, because its suppression of T-bet and IFN regulatory factor-1 was completely abrogated in me(v)/me(v) CD4+ T cells. Receptor-proximal responses to IFN-gamma, such as the induction of Jak-Stat phosphorylation, were inhibited by TGF-beta1 in wild-type T cells, but not in me(v)/me(v) T cells. Consistent with a direct role for Shp-1, TGF-beta1's inhibition of IFN-gamma-induced Stat1 phosphorylation was sensitive to the general PTP inhibitor pervanadate. Together, these data show that TGF-beta1 suppresses IFN-gamma signaling and transcriptional responses in CD4+ T cells through the PTP Shp-1.
Medical manipulators — a realistic concept? (1995)

SummaryAre medical manipulators just wishful thinking by engineers or a real benefit to minimally invasive surgery? Based on an analysis of current practice in minimally invasive surgery, this paper will argue the case for medical manipulators. Three critical components are discussed in detail: the design of the endoscopes and surgical instruments, the man-machine interface and the actual manipulator itself. On the basis of first evaluation results for a virtual prototype of the system, the paper concludes that the first question should be answered with yes.

Photon Correlation Spectroscopy Using a Digital PDP-9 Computer (1972)

Photon correlation spectroscopy has recently been shown to be a fast and accurate method of measuring the translational diffusion constant (D) of macromolecules. The measurement time is so low that it is possible to follow changes in the diffusion constant as a function of temperature, pH, etc. Most of the photon correlators in existence employ an electronic autocorrelator which relies on a clipping process to construct the desired functions. The spectrometer which we describe here is on-line to a Digital PDP-9 computer which is programmed to carry out a complete correlation analysis. Advantages and disadvantages of this technique are discussed.
Compositional Verification in Supervisory Control (2009)

This paper proposes a compositional approach to verifying whether a large discrete event system is nonblocking. The new approach avoids computing the synchronous product of a large set of finite-state machines. Instead, the synchronous product is computed gradually, and intermediate results are simplified using conflict-preserving abstractions based on process-algebraic results about fair testing. Heuristics are used to choose between different possible abstractions. By translating the problem representation, the same method can also be applied to verify safety properties, in particular, controllability. Experimental results show that the method is applicable to finite-state machine models of industrial scale and brings considerable improvements in performance over other methods for nonblocking verification.
Use of Corncob for Endoxylanase Production by Thermophilic Fungus Thermomyces lanuginosus IOC-4145 (2000)

The production of cellulase-f ree endoxylanase by the thermophilic fungus Thermomyces lanuginosus was investigated in semisolid fermentation and liquid fermentation. Different process variables were investigated in semisolid fermentation, employing corncob as the carbon source. The best results were with the following conditions: grain size = 4.5 mm, solid:liquid ratio = 1: 2, and inoculum size = 20% (v/v). Corncob, xylan, and xylose were the best inducers for endoxylanase production. Additionally, organic nitrogen sources were necessary for the production of high endoxylanase activities. The crude enzyme had optimum activity at pH 6.0 and 75°C, displaying a high thermostability. The apparent K m and V max were 1.77 mg of xylan/mL and 21.5 U/mg of protein, respectively.
Histological characterization of abdominal aorta post endovascular autologous transplantation of Mesenchymal Stem cells (MSCs) in Porcine AAA Model (2013)

Introduction MSCs transplantation is being investigated in porcine AAA models for their potential to repair degenerated aorta. This study aims to characterize histological changes in the tissues of porcine AAA models post MSC transplant to build reliable methods of tracking the cells. Methods and Results MSCs were isolated from pig's bone marrow and expanded in vitro. Lenti Virus + GFP transfected to MSCs for 48 hrs. The cells are prepared with mixture of 10% sucrose, puramatrix and PBS. The AAA is induced and MSCs labeled with GFP are injected. The pig is sacrificed 2 wks post surgery and the tissues are collected and formalin fixed for histological staining such as H&amp;E, Trichrome, Pearl, and Picrosirius red(PSR). IHC is performed to localize GFP positive cells. Figure 1A: IHC staining for anti GFP showing bright green signal ‐positive spindle cells at the border of Media and adventitia layer of the tissue. Cluster of MSCs showing two different morphologies, round and spindle shapes indicating differentiation of MSCs within the damaged region. Figure 1B: PSR stains showing distinct color gradient between new collagen fibers in green Vs. old collagen fibers. Figure 2A: H&amp;E stain shows the presence of MSCs. Figure 2B: Trichrome confirms figure 1A findings. Conclusion The histology slides clearly make it easy to visualize MSCs in the aorta post transplant confirming that it is possible to localize and track MSCs.
Extending the Affordance Structure Matrix – Mapping Design Structure and Requirements to Behavior (2008)

Affordance Based Design is a recently developed approach to design theory and methodology based on the theory of affordances from perceptual psychology. An affordance is what one system provides or furnishes to another system [1]. For example, a chair affords sitting to a person. A key advantage of the affordance based approach is that affordances are form-dependent, unlike functions which are
