Efficacy of intravitreal hemocoagulase for control of bleeding in rabbit experimental model of vitrectomy. (1993)

Hemorrhage during vitrectomy for diabetic retinopathy or in the recently traumatized eye can complicate the surgical procedures and might cause termination and failure of vitrectomy in some cases. The effect of the hemocoagulase, Botropase, on the hemostasis of intraocular bleeding was evaluated in a rabbit model by cutting central retinal vessels in the medullary ray. Addition of the hemocoagulase (1 NIH unit/100 ml) to BSS Plus significantly reduced bleeding time. Immediately after vitrectomy with the use of this hemocoagulase, the average of the maximum amplitudes of the b-wave in electroretinography was normal, although the sensitivity of the electroretinogram was reduced by 0.1 log unit in the experimental eyes which were infused with hemocoagulase solution. The sensitivity showed no significant difference after the second postoperative day. The experimental eyes showed no abnormal findings histologically. Infusate containing Botropase appeared to be a useful adjunct for the control of intraocular bleeding during vitreous surgery.
Correlation between fluorescence in-situ hybridization analyses and in-vitro development to blastocyst stage of embryos from Robertsonian translocation (13;14) carriers (2002)

Normal/balanced embryos developed better but the proportion of abnormal blastocysts was still high. Preimplantation genetic diagnosis is recommended to select normal/balanced embryos from RT t(13;14) carriers.
Cold Rolled Texture and Microstructure in Types 304 and 316L Austenitic Stainless Steels (2003)

Two grades of austenitic stainless steel (ASS), types 304 (UNS S 30400) and 316L (UNS S 31603), were cold rolled to different reductions by unidirectional and by cross-rolling. The steels had reasonable difference in stacking fault energy (estimated respectively as 15 and 61 mJ/m2 in types 304 and 316L) and also in starting (or pre-deformation) crystallographic texture-being relatively weak and reasonably strong in types 304 and 316L respectively. The cold rolling increased texturing in type 304, but not in type 316L ASS. The more significant effect of cold rolled texture development was in the relative increase of Brass ({011}‹211›) against Copper ({112}‹111›) and S ({231}‹346›) orientations. In type 304 the increase in Brass was significant, while in type 316L the increase in Copper and S was stronger. This effect could be captured by Taylor type deformation texture simulations considering stronger twinning contributions in type 304-for example the respective ‘best-fits’ (in terms of matching the changes in the volume fractions of Brass against Copper and S) were obtained by full constraint Taylor model with 1 : 100 and 1 : 10 slip : twin activities in types 304 and 316L ASS respectively.Microstructural developments during cold rolling were generalized as strain induced martensite formation and developments of dislocation substructure. The former, as estimated by vibrating sample magnetometer (VSM), increased with cold reduction, being significantly more in type 304 and was also noticeably stronger in both grades under cross-rolling. The most significant aspect of substructural developments was the formation of strain localizations. These were observed as dense dislocation walls (DDWs), micro-bands (MBs) and twin lamellar structures (TLS). The TLS contribution gained significance at higher reductions and during cross-rolling, especially in type 304. Large misorientation development and the accompanying grain splittings were always associated with such strain localizations. Efforts to relate Taylor factor (M) and textural softening (dM/dε) values (of ideal texture components) with relative misorientation developments was, however, unsuccessful. No consistent trend could be established for any unique combination(s) of slip-twin in the respective alloys.
Arthroscopic Management of Dysplastic Hip Deformities (2015)

Arthroscopic management of mild to moderate acetabular dysplasia had inferior good/excellent results and higher failure rates when compared with an FAI cohort; therefore, isolated arthroscopic procedures in this population should be cautiously considered. These results were independent of patient sex. Labral repair and capsular plication resulted in better clinical outcomes in this mildly dysplastic cohort.
On RAKE allocation for CDMA receiver employing antenna arrays (2002)

Utilization of antenna arrays allows capacity enhancement in cellular CDMA networks. For wideband receivers employing antenna arrays a 2D-RAKE receiver is required and a search for best RAKE taps has to be performed in spatio-temporal domain. This simulation study focuses on 2D-RAKE allocation in the mean energy sense assuming a digital beamforming approach. The scheme permits also a straightforward way to downlink beamforming. In the current method a 2D-channel impulse response is evaluated first and then a two-dimensional search gives the RAKE taps with most energy. A wideband spatio-temporal channel model for urban macro cells is employed. The simulations produce the relative signal-to-interference-and-noise ratio (SINR) as a function of the number of allocated RAKE taps and the beamwidth of the antenna array. The results show that SINR gains depend strongly on the angular spread of the desired signal. The enhancement in SINR varied approximately between 6-9 dB for a 10-element antenna when four 2D-RAKE taps were exploited. This improvement can be interpreted as an approximate increase in capacity. Increasing the system bandwidth from 1.25 MHz to 5 MHz only 1-3 additional 2D-RAKE taps were required for maintaining the desired SINR level. In the downlink the performance was about 1-3 dB worse than in the uplink.
A POSSIBILITY FOR LOCAL TARGETING OF MAGNETIC CARRIERS (2004)

This work suggests a new procedure for local targeting of magnetic microentities (magnetic oxide particles, ferro-carbon particles, magnetic polymer particles, magnetic amorphous alloys particles, etc.), by placing small sized ferromagnetic wires in the target area or within the area joining the target and applying an external uniform background magnetic field which has to be perpendicular to the magnetizable wires. The possibility to capture the magnetic microparticles and to build deposits is theoretically studied under circumstances similar to the in vivo ones.
Using Density Measurements to Study the Effect of Excision, Storage, Abscisic Acid, and Ethylene on Pithiness in Celery Petioles (1996)

The density of excised 2-cm celery (Apium graveolens L.) petiole segments was highly correlated with a subjective evaluation of pithiness. Loss of density and the appearance of pithiness was stimulated by lengthening the duration of storage, raising the storage temperatures above 0C, and excising petiole segments. Segments excised from the upper two-thirds of the petiole lost less density during storage than segments excised from the bottom third of the petiole. Segments with initial high densities lost slightly less density during storage at 5C for 5 weeks than segments that were initially less dense. The extent of pithiness development varied significantly among six cultivars held at 5C for 2 weeks. Treating whole petioles with 1 μ m abscisic acid for 4 days significantly increased density loss. Exposing petiole segments to up to 100 μl·liter -1 ethylene in humidified air for up to 2 weeks at 5C did not significantly change density over air controls. The loss of density and the development of pithiness in lightly processed celery petioles could be reduced by selecting resistant cultivars, monitoring water stress during growth, using only segments excised from the upper two-thirds of the petiole, and selecting segments with initial high densities.

Rupture directivity of fluid‐induced microseismic events: Observations from an enhanced geothermal system (2016)

Abstract The rupture process of fluid‐induced microseismic events is still poorly understood, mainly due to usually small magnitudes and sparse monitoring geometries. The high‐quality recordings of the earthquake sequence 2006–2007 at the enhanced geothermal system at Basel, Switzerland, constitute a rare exception, allowing a systematic directivity study of 195 events using the empirical Green's function method. We observe clear directivity signatures for about half the events which demonstrates that rupture directivity persists down to small magnitudes ( M L ∼1). The predominant rupture behavior is unilateral. We further find evidence that directivity is magnitude dependent and varies systematically with distance from the injection source. Whereas pore pressure seems to play the dominant role close to the injection source and no preferred rupture direction is observable, directivity aligns parallel to the event distribution with increasing distance ( m) and is preferably oriented away from the injection point. The largest analyzed events ( M L ∼2) show a distinct behavior: They rupture toward the injection source, suggesting that they nucleate in the vicinity of the pressure front and propagate backward into the perturbed volume. This finding is of particular relevance for seismic hazard assessment of georeservoirs, since it implies that maximum event size is related to dimension of the fluid‐perturbed volume. Our study also resolves rupture complexities for a small group of events. This shows that small fault heterogeneities exist down to a scale of a few tens of meters. The observation of directivity and complexity in induced microseismic events suggest that future source studies account for these phenomena.
Virtual Shear Source: a new method for shear‐wave seismic surveys (2005)

Shear‐wave seismology holds great promise but always remains small niche activity due to a variety of operational and subsurface limitations. In this study we demonstrate that the Virtual Source method can overcome many of these limitations and revive shear‐wave seismology. With an array of sources at the surface this method allows us to obtain a Virtual Shear Source at the location of each downhole geophone in a well. Firstly, in certain cases it allows us to generate pure shear‐wave energy without P‐wave contamination using conventional P‐wave sources even in a marine environment. Secondly, we can construct SS images of the subsurface even through a complex near‐surface for which the velocity model is unknown. Thirdly, we can control the polarization. All this is at a price of placing geophones in the subsurface and making downhole recordings. This price tag is expected to decrease with greater use of permanent downhole monitoring, cheap wells and instrumented oilfields. We will show examples of SS images obtained through a complex near‐surface and show shear‐wave checkshots generated with the help of P‐wave sources even in a marine environment. This development may lead to a renaissance of shear‐wave seismology especially for permanent seismic monitoring.
Design of broadband kilo-watt class W-band serpentine TWTs (2014)

Summary form only given. The design of a traveling-wave tube (TWT) amplifier chain capable of 2.5kW of peak RF output power and > 1.5 kW of power over the frequency band of 92 - 100 GHz will be presented. This amplifier configuration is comprised of a driver TWT and two serpentine TWT power boosters, which are cascaded in series. The driver TWT is driven by a 122 mA, 20 kV electron beam and is expected to yield an RF peak power of 245 W with >100 W of power over a 7 GHz band-width [1]. This driver tube is currently under development [2]. The booster amplifiers are driven by much more intense 533 mA, 20 kV electron beams formed via a novel beam forming approach. The beam is focused by a solenoidal magnetic field of 6 kG in a 420-μm diameter beam tunnel. The higher beam perveance of booster TWTs in this cascaded configuration [3] permits a much higher RF power-bandwidth product out of the first and second booster stages than presently feasible with conventional approaches. Shown in the plot below are the predicted frequency responses of the first and second booster stages with an assumed constant 100 W drive power into the first booster stage. These results are obtained with simulations using the 3D particle-in-cell code Neptune with beam phase space information imported from 3D Gun/Collector code MICHELLE. The booster circuits are very compact with circuit lengths of approximately 2 and 1.4 cm for the first and second booster stages, respectively. Gun and booster designs will be presented and discussed.

Electrochemical Intercalation of Lithium into Graphite in Room-Temperature Molten Salt Containing Ethylene Carbonate (2003)

Electrochemical intercalation of lithium into graphite was investigated in trimethyl--hexylammonium bis(trifluoromethanesulfone)imide (TMHATFSI) room-temperature molten salt containing both lithium bis(trifluoromethanesulfone)imide (LiTFSI) and ethylene carbonate (EC). The electrochemical intercalation of the organic cations into graphite occurred in TMHATFSI molten salt regardless of the presence of LiTFSI. The addition of EC to TMHATFSI molten salt with LiTFSI resulted in the electrochemical formation of the graphite intercalation compound of lithium, probably accompanied by the formation of a solid-electrolyte interface film, which prevents the intercalation of the organic cations. © 2003 The Electrochemical Society.

activity of peptides related to corticotrophin and lipotrophin (1980)

Behavioural activities of peptides related to corticotrophin and lipo­ trophin were studied in active and passive avoidance tests in rats. When searching for an active core in the ACTH-molecule which would be responsible for activity in the pole-jumping test, we found that essential information for this type of activity was not confined to the minimal fragment 4-7, but was also present in the sequences 7-10, Ac-(ll-13)-NH2 and 25-39, indicating a redundance of information. Through the introduction of certain modifications in the sequence ACTH4 _ IO , selectivity of action could be improved and the potency increased a thousandfold. Another increase in potency by a factor of at least 1000 could be obtained by C-terminal elongation with a modified ACTHlf -16 sequence. The finding that [Met5]enkephalin was equally as active as ACTH4 _ 10 in the pole-jumping test was used as an additional argument for the suggestion that the latter peptide assumes an a-helix conformation at the receptor site. When frag­ ments of ~-endorphin were tested for their capacity to inhibit extinc­ tion of a conditioned avoidance response in the pole-jumping test, the sequence 62-76 appeared to be the most active one, whereas in the series of peptides related to y-endorphin which accelerate extinction, the fragment 66-77 appeared to be the shortest one to give a
The Effect of Square Wave Exposure Profiles Upon the Performance of Passive Organic Vapor Monitoring Badges (1984)

Three commercially available passive organic vapor monitoring badges were exposed to ethyl benzene vapor in a dynamic test atmosphere characterized by well defined square wave concentration profiles having periods of 2, 6, and 10 minutes. These concentration fluctuations between zero and 150 ppm caused no significant bias in the TWA concentration indicated by the badges. A slight, but statistically significant, interaction between badge type and exposure profile is attributable to random analytical error in the data provided by one badge type.
Structure-function relationships of the soluble form of the antiaging protein Klotho have therapeutic implications for managing kidney disease (2020)

The fortuitously discovered antiaging membrane protein αKlotho (Klotho) is highly expressed in the kidney, and deletion of the <i>Klotho</i> gene in mice causes a phenotype strikingly similar to that of chronic kidney disease (CKD). Klotho functions as a co-receptor for fibroblast growth factor 23 (FGF23) signaling, whereas its shed extracellular domain, soluble Klotho (sKlotho), carrying glycosidase activity, is a humoral factor that regulates renal health. Low sKlotho in CKD is associated with disease progression, and sKlotho supplementation has emerged as a potential therapeutic strategy for managing CKD. Here, we explored the structure-function relationship and post-translational modifications of sKlotho variants to guide the future design of sKlotho-based therapeutics. Chinese hamster ovary (CHO)- and human embryonic kidney (HEK)-derived WT sKlotho proteins had varied activities in FGF23 co-receptor and β-glucuronidase assays <i>in vitro</i> and distinct properties <i>in vivo</i> Sialidase treatment of heavily sialylated CHO-sKlotho increased its co-receptor activity 3-fold, yet it remained less active than hyposialylated HEK-sKlotho. MS and glycopeptide-mapping analyses revealed that HEK-sKlotho is uniquely modified with an unusual <i>N</i>-glycan structure consisting of <i>N</i>,<i>N</i>'-di-<i>N</i>-acetyllactose diamine at multiple <i>N</i>-linked sites, one of which at Asn-126 was adjacent to a putative GalNAc transfer motif. Site-directed mutagenesis and structural modeling analyses directly implicated <i>N</i>-glycans in Klotho's protein folding and function. Moreover, the introduction of two catalytic glutamate residues conserved across glycosidases into sKlotho enhanced its glucuronidase activity but decreased its FGF23 co-receptor activity, suggesting that these two functions might be structurally divergent. These findings open up opportunities for rational engineering of pharmacologically enhanced sKlotho therapeutics for managing kidney disease.
Occurrence Condition of Electric Current Density in Electrical Pitting (2010)

Recently, several problems owing to electrical pitting have been observed to be extremely common in small bearings. Many researchers reported on the electrical pitting of bearings used for railcars. This paper deals with a fundamental experiment for electrical pitting in a small bearing (608). Experiments lasting 500 hours with conducting direct current between balls and raceways made it clear that the electrical pitting occurred at an electrical current density of about 0.04A/mm2. This electrical current density was very small compared with that considered in conventional research.
DARE IIIB — a CSSL-type batch-mode simulation language for CDC 6000-series computers (1972)

This paper describes a batch-mode FORTRAN-based continuous-system simulation language possessing most of the desirable features specified by the Simulation Council's CSSL committee. Of course, there are already many continuous-system simulation languages, such as DSL/90 and CSMP (block- oriented), MIMIC, SL-1, CSSL III, etc.; however, to the writers' knowledge, only MIMIC and CSSL III are currently available for CDC-6000 series systems. MIMIC, while equation-oriented, is not as powerful as CSSL III, is somewhat rigid in format, and hard to modify. CSSL III usage involves a surcharge to the program originator, and is thus not attractive for educational applications. DARE IIIB, locally developed under NSF sponsorship, is a modern CSSL-type language, almost as powerful as CSSL III, that is available to any potential user for the cost of a magnetic tape. DARE IIIB is structured to permit convenient user modification, e.g., it is relatively easy to add new integration rules, run-time strategies, or special library subprograms. Problem equations are entered in a form close to ordinary mathematical notation; the associated proce dural language is FORTRAN. User-chosen variable names in the problem description are accommodated by a translation phase. Run-time data is entered via standard FORTRAN IV namelist data cards. A variety of output options are provided, including line- printer listings and plots, and CalComp plotter dis plays. Single- or multiple-run problems may be specified, with storage files used for saving output data for subsequent cross-plotting, reentry into future runs, etc. In addition to an internal collection of library functions, special functions may be specified in FORTRAN, and one-or-two variable table lookup function generation is provided. DARE IIIB provides a choice of several internal fixed- and variable-step integra tion rules; the user can insert his own run-time con trol subroutine for special application. The system is presently implemented on a CDC 6400 with 65K of core memory (SCOPE 3.2 operating system), and an off-line CalComp plotter. DARE IIIB can accommodate problems with 100 parameters, 200 state variables, and 350 output variables. This paper describes the major features of the lan guage, and presents basic user information, and several examples. Inquiries regarding this software package should be addressed to Professor John V. Wait.
