Surface modification of polysulfone membranes by low-temperature plasma-graft poly(ethylene glycol) onto polysulfone membranes (2000)

A novel and general method of modifying hydrophobic polysulfone (PSF) to produce highly hydrophilic surfaces was developed. This method is the low-temperature plasma technique. Graft polymer-modified surfaces were characterized with the help of Fourier transform infrared attenuated total reflection (FTIR–ATR) and X-ray photoelectron spectroscopy (XPS). Study results demonstrated that poly(ethylene glycol) (PEG) could be grafted onto the PSF membrane surface by low-temperature plasma. The hydrophilic character of the modified surfaces was increased in comparison with that of the parent membrane. The contact angle for a modified PSF membrane was reduced apparently. We analyzed the effectiveness of this approach as a function of plasma operating variables including plasma treatment power and treatment time. Hence, plasma-induced graft polymer modification of membranes can be used to adjust membrane performance by simultaneously controlling the surface hydrophilicity and hemocompatibility. © 2000 John Wiley & Sons, Inc.

Powder X-ray diffraction and Rietveld analysis of La <sub> 1− <i>x</i> </sub> Ba <sub> <i>x</i> </sub> CoO <sub>3</sub> (0< <i>x</i> ≤0.5) (2006)

Detailed structural properties of La 1− x Ba x CoO 3 (LBCO) have been investigated by means of X-ray powder diffraction and Rietveld analysis. A structural phase transformation from R 3 c to P m 3 m at x =0.30–0.35 has been detected based on a comparison between the refinements of R 3 c and P m 3 m . The Co–O bond length of the CoO 6 octahedron expanded rapidly with increasing Ba content when x <0.1, and then it leveled off and kept constant at 0.1⩽ x ⩾0.35, where the Co–O–Co bond angle reaches 180°. The Co–O bond length expansion resumed with increasing Ba content beyond x =0.35.
Effect of Tetralin, Decalin and Naphthalene as Hydrogen Donors in the Upgrading of Heavy Oils (2012)

Nowadays the upgrading of heavy crude oils is achieved by thermal cracking or hydrocracking, which are based on the carbon rejection and hydrogen addition routes. These processes have several problems yet to be solved, such as coke deposition both on the reactor walls and on the catalyst, low quality of products and low efficiency of usage of hydrogen. Thus, an efficient technology for the production of high quality distillates from heavy oils or residua has not been developed yet. An interesting alternative for improving the yield of valuable liquid products in the hydroprocessing of heavy feeds is the use of hydrogen donors (usually polycyclic naphthenic-aromatic or naphthenic compounds that can be reversibly hydrogenated-dehydrogenated in the reacting mixture). The molecules of the hydrogen donors are dehydrogenated, transferring hydrogen atoms to the heavy hydrocarbons in the oil, thus improving the quality of the cracked products and minimizing the polymerization of the heavier molecules via a free radicals mechanism. This work is focused on the effect of tetralin, decalin and naphthalene as hydrogen donors (Hdonors) in the thermal cracking of a Mexican heavy crude oil (12.1 °API) in the presence of hydrogen or methane as reducing agents. Experiments were carried out in a batch reactor under relatively mild conditions, 1.1 MPa initial pressure and 693 K temperature. The results indicate that the combination of these H-donors and reducing agentsleads to significant reductions in the yield of coke, compared to those obtained using only the reducing agents under the same conditions. The improvements in the API gravity, the viscosity and the distillates yield (as determined by GC-simulated distillation) upon treatment are nearly the same with or without H-donors, confirming that the primary cracking reactions depend mainly on the temperature of reaction and are not appreciably affected by the presence of reducing agents or hydrogen donors. The reduction in the yield of coke was similar for tetralin, decalin and naphthalene.

Performance optimization of LDPC codes using selective coding approach and beacon parity check matrix (2010)

In this paper we have presented a novel idea to optimize the performance of Low Density Parity Check (LDPC) Codes by using selective encoding and decoding approach. We have also proposed a new simplified form of parity check matrix, h named as beacon matrix which is useful for the efficient implementation of the proposed scheme. The proposed scheme is more suitable for real time applications like voice and video where bandwidth and delay are important considerations. The simulation results validate that bit error rate (BER) performance of LDPC codes is improved significantly by using the proposed scheme.
Blooming Suppression in Charge Coupled Area Imaging Devices (1972)

An intense spot of light projected onto the photo-sensitive surface of an imaging device can cause this device to saturate locally. Excess carriers generated by the light source can diffuse into the neighboring area which may also be driven into saturation. In the display the light source will then appear as a white area that can be considerably larger than its image in the true geometrical proportions. This effect, known as blooming, is present in most TV camera tubes, and demands special care by the operator to avoid bright objects in the scene being imaged. For the Picturephone <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">®</sup> camera, which often has to operate in less than ideal conditions, the design of a camera with limited blooming is thus more than desirable.
Correlation of T and B cell activities in vitro and serum IL-2 levels in systemic lupus erythematosus. (1988)

There have been only a few studies indicating that B cell hyperactivity in SLE could depend on Th cell activation. In particular, circulating CD4+ cells were found to express Ia. Our own previous investigations have shown that the decreased IL-2 secretion capacity in vitro of CD4+ cells in SLE is restored to normal when the cells are rested for a few days in culture. This suggested the presence of activated, exhausted T cells in the circulation. In this study, we report several observations concerning T cell function in SLE. 1) Decreased IL-2 secretion in vitro of PBL was found to correlate significantly with increased spontaneous IgG secretion of such cells; immunosuppressive treatment of 22 patients with steroids plus cyclosporin A led, to a large extent, to a correction of both abnormalities. 2) 9 of 18 patients with active disease (and low IL-2 secretion in vitro) had increased IL-2 levels in serum by ELISA; two sera contained IL-2 biologic activity, and chromatography of one serum showed IL-2 in a high molecular size complex (Mr approximately 50,000) dissociable with 6 M urea. The serum levels of IL-2R were also frequently increased, even in less active SLE. 3) In cell culture experiments, the IgG secretion by purified B cells from 6 of 9 patients with active SLE was increased by autologous T cells acting either alone (3 patients) or synergistically with rIL-2 (3 patients); the B cells from all 9 patients showed increased IL-2 responsiveness compared with blood donor B cells. Taken together, these results provide new evidence that increased T cell activation occurs and plays a role in SLE.
Nine years' experience of physiological correction of tricuspid atresia: long-term results and current surgical approach. (1982)

Fontan's correction has been performed without early death in 24 consecutive patients with tricuspid atresia. Eighteen patients had ventriculoarterial concordance (group I) and six discordance (group II). Late death related to infections occurred in three patients. The follow-up time in group I (16 survivors) ranges from 1 year 10 months to 7 years 5 months (mean 3 years 8 months) and in group II (five survivors) from 2 years 1 month to 5 years 6 months (mean 3 years 6 months). Early postoperative cardiac catheterisation showed arterial pulsatile pressure recordings in the pulmonary artery only in two patients in group I, in whom a valved conduit was used to connect the right atrial appendage with the outlet chamber. Patients with a valved conduit connected with either the pulmonary artery (group II) or the outlet chamber (two patients of group I) showed better preservation of right atrial contractions angiocardiographically and scored better in exercise tests than did patients with a non-valved conduit (14 patients of group I). In the latter patients evidence of regurgitant bloodflow from the outlet chamber into the right atrium was found. Reoperation was necessary in two patients. The outlet chambers showed a substantial increase in diameter after operation. No disturbances of kidney or liver function were found up to seven years after operation. The clinical condition has improved considerably in all survivors. It is concluded that the use of a valved conduit is preferable for connecting the pulmonary artery directly in cases of tricuspid atresia with ventriculoarterial discordance or the outlet chamber when there is ventriculoarterial concordance.
Programmable Memory Trends in the Automotive Industry (1990)

<div class="htmlview paragraph">Semiconductor memory has served as a driving force behind integrated circuit chip technology over the past three decades at the same time as it has revolutionized the computer, consumer electronics, and industrial electronics industries. Recent developments in low cost reprogrammable memory technologies have added new dimensions of flexibility, serviceability, customization, and intelligence to electronic subsystems. These features are of particular value to automobiles of the future. Uses of UV-erasable EPROM's, electrically erasable EEPROM's, and related Flash erasable EEPROM's are already beginning to revolutionize powertrain and embedded controller applications, and it is anticipated that they will rapidly pervade additional safety, driver information, and comfort applications in the coming decade. Reprogrammable memory is also expected to enable the “intelligent automobile” of the future, capable of self diagnosis, repair, and navigation, as well as revolutionizing the driver vehicle interface.</div>
VisualSEEk (1996)

We describe a highly functional prototype system for searching by visual features in an image database. The VisualSEEk system is novel in that the user forms the queries by diagramming spatial arrangements of color regions. The system finds the images that contain the most similar arrangements of similar regions.
Weak infinitesimal generator for a stochastic partialdifferential equation with time delay (1995)

In this paper, we consider the Markov solution process for a stochastic parabolic differential equation with time delay. Under the Lipschitz condition and boundedness on the drift and diffusion coefficient, properties of the weak infinitesimal generator of the associated Markov operators are established. Actions of the weak infinitesimal generator on the space of quasi‐tame functions are also investigated.
Occludin Phosphorylation in Regulation of Epithelial Tight Junctions (2009)

Occludin is the first transmembrane protein of the tight junction to be discovered. While numerous studies emphasized the important role of occludin in assembly and maintenance of tight junctions, occludin knockout studies indicated that it was not required for tight junction assembly in different epithelia. However, a detailed characterization of the occludin knockout mouse concluded that the occludin gene is indispensable, and plays a complex role in regulation of epithelial tight junctions in different organs. This article describes the role of occludin phosphorylation in the regulation of its assembly into the tight junctions. Occludin is highly phosphorylated on Ser and Thr residues, while Tyr-phosphorylation is kept at minimum in the intact epithelium. During the disruption of tight junctions by various factors, occludin undergoes dephosphorylation on Ser/Thr residues and elevated phosphorylation on Tyr residues. The phosphorylation of occludin on Tyr, Ser, and Thr residues appears to be regulated by the balance between protein kinases such as c-Src, PKCzeta, and PKClambda/iota, and protein phosphatases such as PP2A, PP1, and PTP1B. The precise mechanism of regulation of the tight junction by occludin phosphorylation is unclear at this time. However, an in vitro study indicated that Tyr-phosphorylation of occludin C-terminal domain attenuates its interaction with ZO-1. Therefore, phosphorylation of specific Ser/Thr/Tyr residues in occludin may regulate its interactions with ZO-1 and possibly other tight junction proteins. It is likely that occludin plays a regulatory role in tight junctions rather than a role in the de novo assembly of tight junctions.

Drug-eluting stents: an early systematic review to inform policy*1, *2 (2004)

The early data available indicate that DES reduce adverse cardiac events, mainly revascularisations. However, these data are limited in terms of patient numbers, length of follow-up, and method of outcome assessment. The evaluation of rapidly evolving technologies requires the inclusion of data not routinely considered for inclusion in systematic reviews of effectiveness.
Quantification of 17β-estradiol residues in bovine serum by liquid chromatography-tandem mass spectrometry with atmospheric pressure chemical ionization† (1998)

A method for the quantification of the natural hormone 17 beta-estradiol (17 beta-E2) in bovine serum by liquid chromatography atmospheric pressure chemical ionization tandem mass spectrometry (LC-APCI-MS-MS) was developed. Ethinylestradiol (EE2) was used as internal standard. Analytes were extracted from serum using acetate buffer, purified by C18 solid-phase extraction (SPE) and chromatographed on a polymeric reversed-phase (PLRP-S) LC column. They were ionized in a heated nebulizer (HN) interface operating in the negative ion mode, where only the intact deprotonated molecules, [M - H]-, were generated at m/z 271 and 295 for 17 beta-E2 and EE2, respectively. These served as precursor ions for collision-induced dissociation (CID) and diagnostic product ions were identified for the unambiguous hormone confirmation by selected reaction monitoring (SRM) LC-APCI-MS-MS. The method was validated on bovine serum and the limit of quantification (LOQ) was 30 pg ml-1 for 17 beta-E2. The inter-day precision (relative standard deviation, RSD) and accuracy (relative error, RE) derived from the analyses of validation samples at three concentrations ranged from 1.76 to 3.76 and from -4.18 to -2.01%, respectively. This method is currently being successfully applied to measure the bovine serum concentration of 17 beta-E2 in order to discriminate between the physiological concentrations of 17 beta/E2 and the hormone levels resulting from illegal administration.
Use of noun phrases in identification of a website (2017)

In this paper a methodology is proposed to prepare a domain ontology of a given website. For the same we parse through the contents of website for noun pharses. We apply Term Frequency and Inverse Document Frequency (TF-IDF). This gives us the required information about the domain which can be used to build an ontology. The ontology thus created will represent the proper taxonomy of classes and their interrelationships. This ontology will help in identification of topics in website and ability to give relevant output when complex queries are given. The system will then make use of the ontology to classify it in comparison with the ontologies in the database. The system is tested on an academic instritutes website, namely, College of Engineering Pune (COEP) and proves to be useful.
Iso-concentration hydrogen peroxide bleaching of poplar chemi-thermomechanical pulp (2018)

Maintaining a constant chemical concentration (Iso-concentration, IC) has been found to be an effective method to improve peroxide bleaching efficiency for chemi-thermomechanical pulp (CTMP). In this study, the mechanism of IC bleaching was investigated. The concentrations of H<sub>2</sub>O<sub>2</sub> and total alkali in IC bleaching were monitored and compared with those in conventional bleaching processes. Control experiments without pulp were carried out to explore the effects of bleaching additives on H<sub>2</sub>O<sub>2</sub> decomposition. The results showed that the concentrations of H<sub>2</sub>O<sub>2</sub> and the total alkali at the early and later stages of IC bleaching were relatively low and high, respectively; thus, undesired decomposition of H<sub>2</sub>O<sub>2</sub> was inhibited, and brightness was improved. Moreover, the stabilizer played an important role in inhibiting the undesired H<sub>2</sub>O<sub>2</sub> decomposition. This may explain why high bleaching efficiency was achieved in IC bleaching. These findings would provide valuable insight for the production of high-brightness bleached chemi-thermomechanical pulp (BCTMP).
Soft wall-climbing robots (2018)

Existing robots capable of climbing walls mostly rely on rigid actuators such as electric motors, but soft wall-climbing robots based on muscle-like actuators have not yet been achieved. Here, we report a tethered soft robot capable of climbing walls made of wood, paper, and glass at 90° with a speed of up to 0.75 body length per second and multimodal locomotion, including climbing, crawling, and turning. This soft wall-climbing robot is enabled by (i) dielectric-elastomer artificial muscles that generate fast periodic deformation of the soft robotic body, (ii) electroadhesive feet that give spatiotemporally controlled adhesion of different parts of the robot on the wall, and (iii) a control strategy that synchronizes the body deformation and feet electroadhesion for stable climbing. We further demonstrate that our soft robot could carry a camera to take videos in a vertical tunnel, change its body height to navigate through a confined space, and follow a labyrinth-like planar trajectory. Our soft robot mimicked the vertical climbing capability and the agile adaptive motions exhibited by soft organisms.
The fragile X syndrome: exploring its molecular basis and seeking a treatment (2006)

Fragile X syndrome (FXS) - the leading cause of inherited mental retardation - is an X-linked disease caused by loss of expression of the FMR1 (fragile X mental retardation 1) gene. In addition to impairment of higher-cognitive functions, FXS patients show a variety of physical and other mental abnormalities. FMRP, the protein encoded by the FMR1 gene, is thought to play a key role in translation, trafficking and targeting of mRNA in neurons. To better understand FMRP's functions, the protein partners and mRNA targets that interact with FMRP have been sought. These and functional studies have revealed links with processes such as cytoskeleton remodelling via the RhoGTPase pathway and mRNA processing via the RNA interference pathway. In this review, we focus on recent insights into the function of FMRP and speculate on how the absence of FMRP might cause the clinical phenotypes seen in FXS patients. Finally, we explore potential therapies for FXS.
The Polycystic Ovary. I. Clinical and Histologic Features (1962)

The clinical, histologic and laboratory findings in 466 cases of surgically proven polycystic ovaries collected from the literature were reviewed and compared with the findings in our series of 39 patients. The variability of the clinical features did not support the hypothesis of an associated syndrome. The histologic studies in the present series also failed to define a consistent entity. Wedge resection resulted in improvement of menstrual function in from 6 to 93 % of cases (in our series, 58%), and in pregnancy in 13 to 95% of cases (in our series, 33%). This further illustrates the lack of homogeneity in the clinical material. It was not possible to predict the results of surgery from clinical findings or urinary steroid studies. Evidence for the occasional coexistence of a hyperadrenal state was strong.
