Line code conversion for high speed optical transmission systems—some comparisons (1989)

Abstract High speed code converters for mBnB and bit insertion codes are compared in terms of their hardware complexity. To overcome some of the problems of fast mBnB code conversion a new design is described using 5B6B as an example. Designs use a clocked multiplexing module. Results highlight the trade-off between coding efficiency, transmission performance and hardware complexity.
Blood-group-related carbohydrate antigens are expressed on human milk galactosyltransferase and are immunogenic in rabbits (1986)

Immunochemical evidence is presented for the presence of blood-group-related carbohydrate structures on human milk galactosyltransferase and for the occurrence of the corresponding specificities among rabbit antibodies to this enzyme. Although these carbohydrate specificities constitute minor populations among antisera and affinity-purified antibodies to galactosyltransferase, their presence is important in the immunohistochemical approach to enzyme localization, since they give rise to strong reactivities with epithelial cells of the gastrointestinal tract.
Hyperemia prior to acute brain swelling during rewarming of patients who have been treated with moderate hypothermia for severe head injuries (2003)

Hyperemia, detectable by TCD ultrasonography, may serve as an index in the prediction of acute brain swelling, and rewarming should be terminated when such a hemodynamic phenomenon is observed.
An Energy-Efficient Water-Filling Algorithm for OFDM Systems (2010)

In this paper, we develop an energy-efficient power allocation algorithm for the parallel channels of an OFDM system. This algorithm provides the optimum solution to a nonlinear fractional program involving an objective function called energy-per-goodbti (EPG). The EPG objective function models the impact of both transmit power and constant circuit power consumption. The energy minimization problem formulation is quite general and subsumes both maximize rate (MR) and maximize margin (MM) problems as specific cases. As a result, the energy efficiency viewpoint provides a convenient and unified perspective of the various water-filling solutions. Using a numerical example, we show that the energy-efficient solution is quite different from the MM or MR solutions and can provide several dBs of performance improvement. We also study the impact of rounding to discrete constellation sizes.
Chlamydomonas .alpha.-tubulin is posttranslationally modified by acetylation on the .epsilon.-amino group of a lysine (1985)

Previous work has shown that the principal alpha-tubulin within Chlamydomonas reinhardtii flagellar axonemes differs from the major alpha-tubulin in the cell body. These two variants of alpha-tubulin are related to one another since posttranslational modification of the cell body form converts it to the axonemal form. When flagella are induced to assemble in the absence of de novo protein synthesis, tritiated acetate can be used to posttranslationally label alpha-tubulin in vivo, and under these conditions, no other flagellar polypeptides exhibit detectable labeling [L'Hernault, S. W., & Rosenbaum, J. L. (1983) J. Cell Biol. 97, 258-263]. In the present report, this labeling method has been used to provide material for chemical analysis of the tritiated moiety that is posttranslationally added to flagellar alpha-tubulin. This radioactivity was volatile after acid hydrolysis, suggesting that the posttranslational modification is the addition of neither an amino acid nor carbohydrate. Treatment of posttranslationally 3H-labeled alpha-tubulin with hydrazine yields radioactive acetylhydrazine, indicating that the moiety involved in posttranslational modification is an acetyl group. Analysis of complete proteolytic digests by thin-layer chromatography has revealed that this acetyl group is located on the epsilon-amino group of a flagellar alpha-tubulin lysine residue.
The martian surface UV environment: theoretical modelling and in-situ measurements (2002)

The UV environment on planetary surfaces is of extreme importance in a wide range of scientific disciplines, from meteorological considerations to the viability of biological organisms. Presented here is theoretical modelling for the transmission of ultraviolet radiation (190-400nm) through the martian atmosphere for a variety of possible cases, resulting in surface spectra. Knowledge of the UV transmission gives in-sight into how significant dust presence on Mars interacts with incoming solar radiation, and also yields information on the effect of biologically damaging UV-C on organisms and organic products on the surface. Surface fluxes are calculated using a radiative transfer approximation, for a range of dust loading and ozone abundance. Effects of direct and diffuse illuminance are also highlighted. In-situ measurements of the UV flux will be possible for the first time onboard the Beagle 2 probe, scheduled to land on Mars in 2003. The instrument will measure the flux at five passbands in the UV, and also measure the total UV dose between 200-400nm throughout the mission lifetime.
The Masquerade of Male Masochists: Two Tales of Translation of the Zhou Brothers (Lu Xun and Zhou Zuoren) in the 1910s (2014)

Through reading two creatively translated stories by the Zhou brothers, Lu Xun’s (Zhou Shuren) “The Soul of Sparta” (Sibada zhi hun, 1903) and Zhou Zuoren’s “The Chivalrous Slave Girl” (Xia nunu, 1904), this paper takes a close look at the intellectual trend in the first decade of the twentieth-century China of constructing strong and heroic women as the emblem of national power while rendering men as powerless. By focusing on a foreign heroine with traditional Chinese virtues, both translations creatively Sinicized and feminized the foreign power in the original tales. At the same time, male characters, prospective readers of the stories, and even authors themselves were marginalized, diminished, and ridiculed vis-a-vis the newly constructed feminine authority. Comparing this form of cultural masochism to other literary masochisms in modern China analyzed by Rey Chow and Jing Tsu respectively, this paper endeavors to excavate a hybrid model of nationalist agency grounded in the intertwined relationship of race, gender and nation. In my analysis, Gilles Deleuze’s discussion on masochism is utilized as a heuristic tool to shed light on the revolutionary potential embedded in the “strong women, weak men” complex in the 1910s. I argue that the cultural masochism in late Qing represents one of the earliest attempts of the Chinese intellectuals to creatively use Chinese traditional gender cosmology to absorb the threat of Western imperialism and put forward a hybrid model of nationalist agency.
A Phase II study of gemcitabine and cisplatin in chemotherapy-naive, unresectable gall bladder cancer (2004)

The primary objective of this study was to determine the response rates of the gemcitabine and cisplatin combination in unresectable gall bladder cancer patients. The secondary objectives were to evaluate the toxicity, time to progressive disease, and overall survival. Chemonaïve patients with histologically proven, unresectable bidimensionally measurable gall bladder cancer were enrolled into this study. All patients were required to have a Zubrod's performance status <or=2, no prior radiotherapy, and adequate major organ function. Patients received gemcitabine (1000 mg x m(-2) intravenously over 30-60 min) on days 1 and 8, and cisplatin (70 mg x m(-2) intravenously over 2 h) on day 1, every 21 days. Response assessment was done by a CT scan after every other cycle of chemotherapy. In all, 30 patients were eligible for efficacy and toxicity analysis. There were four (13.3%) complete responders, seven (23.3%) partial responders, and seven (23.3%) with stable disease, with four (13.2%) patients showing disease progression. The median time to progression was 18 weeks (95% confidence interval (CI) 14-24 weeks), and the median duration of response was 13.5 weeks (range 5.5-104 weeks). The median overall survival was 20 weeks (95% CI 14-31 weeks), with 1-year survival rate of 18.6%. WHO grade 3 or 4 anaemia was seen in seven (23.3%) and four (13.3%) patients, respectively. Five (16.6%) patients each experienced grade 3 or 4 neutropenia, and grade 3 or 4 thrombocytopenia was seen in three (10%) and two (6.6%) patients, respectively. The present study shows that gemcitabine/cisplatin combination is well tolerated and active in advanced unresectable gall bladder cancer.

MEASUREMENT OF YIELD STRESS IN DARK CHOCOLATE USING CONTROLLED STRESS VANE METHOD (2006)

ABSTRACT The controlled stress vane method was used to measure the yield stress in dark chocolate. Three vanes with different L/D ratios and five different stress rates were used in three different chocolate formulations. The vane displacement data did not indicate a definite yield phenomenon. When the vane displacement data were transformed into a ratio of vane velocity to elapsed time, the square root of vane velocity (SV) or the cube root of displacement, a definite yield phenomenon was observed. The SV was preferred on the basis of physical considerations and the linear regression of its derived yield stress on vane dimensions, stress rate and chocolate particle size. The value of the yield stress was the least when determined for a vane height to diameter ratio of 2 and at a stress rate of 3 Pa/min using the SV transformation.
PS-341 (Bortezomib) Induces Lysosomal Cathepsin B Release and a Caspase-2-dependent Mitochondrial Permeabilization and Apoptosis in Human Pancreatic Cancer Cells (2006)

PS-341 (bortezomib) is a potent and reversible proteosome inhibitor that functions to degrade intracellular polyubiquitinated proteins. PS-341 induces apoptosis and has shown broad antitumor activity with selectivity for transformed cells. We studied the effect of PS-341 on lysosomal and mitochondrial permeabilization, including the role of caspase-2 activation in apoptosis induction in the BxPC-3 human pancreatic carcinoma cell line. PS-341 induced a dose-dependent apoptosis in association with reactive oxygen species generation and cleavage of caspase-2 to its 33- and 14-kDa fragments. PS-341 disrupted lysosomes with redistribution of cathepsin B to the cytosol, as shown using fluorescence confocal microscopy, that was blocked by the free radical scavenger tiron but not by a caspase-2 inhibitor (benzyloxycarbonyl (Z)-VDVAD-fluoromethyl ketone (FMK)). PS-341-induced caspase-2 activation was attenuated by a selective pharmacological inhibitor of cathepsin B (R-3032), suggesting that cathepsin B release occurs upstream of caspase-2. PS-341-induced mitochondrial depolarization was attenuated by Z-VDVAD-FMK, tiron, and an inhibitor of the mitochondrial permeability transition pore (bongkrekic acid). Regulation of mitochondrial permeability by caspase-2 was confirmed using caspase-2 small interfering RNA. PS-341-induced cytochrome c release and phosphatidylserine externalization were attenuated by Z-VDVAD-FMK and partially by R-3032. PS-341 activated the BH3-only proteins Bik and Bim and down-regulated Bcl-2 and Bcl-xL mRNA and protein expression. Taken together, PS-341 induces lysosomal cathepsin B redistribution upstream of caspase-2. Caspase-2 activation regulates PS-341-induced mitochondrial depolarization and apoptosis, suggesting that caspase-2 can serve as a link between lysosomal and mitochondrial permeabilization.
The human IL-2 receptor gene contains a positive regulatory element that functions in cultured cells and cell-free extracts. (1987)

The 130-base pair fragment located between 220 and 90 base pairs upstream of the major transcription initiation site of the human interleukin 2 (IL-2) receptor gene had positive regulatory effect on the early promoter of simian virus 40 as well as its own promoter. This fragment seems to be responsible for not only cell-specific but also lymphokine-induced expression of the IL-2 receptor gene as assessed by DNA transfection. The same DNA fragment directed cell-specific transcription of the IL-2 receptor gene in extract of HTLV-I-infected T cells, MT-1, but not of Epstein-Barr virus-transformed B cells, CESS. The addition of small amounts of MT-1 extract to CESS extract resulted in specific expression of the IL-2 receptor gene, indicating that cell-specific expression is regulated by trans-acting molecules in MT-1 extract.
Calculating posterior cystic fibrosis risk with echogenic bowel and one characterized cystic fibrosis mutation: Avoiding pitfalls in the risk calculations (1999)

We describe a general approach to derive fetal risk following two separate test results that each raise the likelihood of the same fetal abnormality without clearly determining whether the abnormality exists. Echogenic bowel observed on fetal ultrasonography may have multiple causes, including an a priori risk of approximately 1% of cystic fibrosis (CF). On numerous occasions our laboratory tests have detected only normal cystic fibrosis transmembrane regulator (CFTR) alleles in fetuses with echogenic bowel. This result indicates that another cause most likely explains the abnormal ultrasound finding. One of our tested fetuses was heterozygous for the deltaF508 CFTR mutation and had a normal karyotype. Over 770 CFTR mutations have been described, and a significant proportion of parental mutant alleles could not be detected by our 25-mutation test. Further mutation analysis demonstrated that the fetus' mother carried the deltaF508 mutation but the father (of different ethnic background than the mother) did not carry a detectable mutation. Thus, this test result substantially increased the risk of the fetus having CF, while still not giving a definitive answer to whether the fetus was affected. A rigorous mathematical analysis determined that the 1% risk of CF following ultrasound study was increased to slightly under 12% following DNA analysis. The case is described, and the mathematical formulas are explained and illustrated with examples, along with a review of conditional probability (Appendix 2).
Quantifying axonal loss after optic neuritis with optical coherence tomography (2006)

Determination of RNFL thickness may predict visual recovery after ON, and lower RNFL values correlate with impaired visual function. Optical coherence tomography may have a potential role as a surrogate marker for axonal integrity within the optic nerve among patients with ON.
Plasma remediation of perchloroethylene in humid gas streams (1995)

Perchloroethylene (PCE) is one of a class of industrial solvents for which alternate disposal strategies are being investigated. Among these strategies is plasma remediation. In this paper we report on a computational study of the plasma remediation of PCE using repetitively pulsed dielectric barrier discharges. We discuss the dominant reaction pathways in the remediation of PCE and show that remediation is significantly improved in humid gas mixtures. Although plasma remediation does not totally oxidize PCE to the desired end-products (CO2 and HCl), the dominant end-products are more easily treated than PCE and can be disposed of using conventional methods.
Syntheses of derivatives of <i>N</i>-acetyl-<scp>D</scp>-lactosamine from <scp>D</scp>-lactal hexaacetate. Hexa-<i>O</i>-acetyl-2-deoxy-2-phthalimido-β-<scp>D</scp>-lactosyl chloride (1982)

Two reaction routes are presented for the preparation of hexa-O-acetyl-2-deoxy-2-phthalimido-β-D-lactosyl chloride (7) from lactal hexaacetate (1). One route involves, in the first stage, reaction of 1 with nitrosyl chloride and proceeds by way of benzyl 2-amino-2-deoxy-α-D-lactoside (4) as an intermediate. The other route, which is considered more efficient, involves reaction of 1 with cerie ammonium nitrate and sodium azide and involves the β-anomer (12) of 4 as an intermediate. The preparation of 7 is of interest as a reagent for the preparation of 2-amino-2-deoxy-β-D-lactosides. The procedures offer routes for the preparation of D-lactosamine.
Comparative studies of poly(dimethyl siloxanes) using automated GPC-MALDI-TOF MS and on-line GPC-ESI-TOF MS (2003)

In this study we compare on-line gel permeation chromatography (GPC) electrospray ionization (ESI) time-of-flight (TOF) mass spectrometry (MS) to automated GPC matrix assisted laser desorption ionization (MALDI) TOF MS for poly (dimethylsiloxane) (PDMS) analysis. Average mass values for a hydroxyl-terminated PDMS (OH-PDMS) sample were obtained and compared to traditional GPC that was calibrated with narrow polystyrene standards, by direct ESI and MALDI MS analysis, by a summation of mass spectra of all GPC fractions, and also by the recalibration method determined by both mass spectrometric methods. Quantitatively, the difference noted here between these hyphenated techniques is that GPC-ESI-TOF MS effectively reports the low-mass oligomers and underestimates the high-mass oligomers, while GPC-MALDI-TOF MS effectively reports the high-mass oligomers and underestimates the low-mass oligomers. In the GPC-ESI-TOF MS experiments, ion current suppression was observed in the high molecular weight region. The suppression effect was confirmed by repeatable sample runs and by injecting different PDMS samples. Higher chromatographic resolution was observed for GPC-ESI-TOF MS compared to GPC-MALDI-TOF MS. In fact, truly mono-disperse oligomers were observed in the low molecular weight range from GPC-ESI MS experiments.
On-Chip Fluorescence-Activated Cell Sorting by an Integrated Miniaturized Ultrasonic Transducer (2009)

An acoustic microfluidic system for miniaturized fluorescence-activated cell sorting (microFACS) is presented. By excitation of a miniaturized piezoelectric transducer at 10 MHz in the microfluidic channel bottom, an acoustic standing wave is formed in the channel. The acoustic radiation force acting on a density interface causes fluidic movement, and the particles or cells on either side of the fluid interface are displaced in a direction perpendicular to the standing wave direction. The small size of the transducer enables individual manipulation of cells passing the transducer surface. At constant transducer activation the system was shown to accomplish up to 700 microm sideways displacement of 10 microm beads in a 1 mm wide channel. This is much larger than if utilizing the acoustic radiation force acting directly on particles, where the limitation in maximum displacement is between a node and an antinode which at 10 MHz is 35 microm. In the automatic sorting setup, the system was demonstrated to successfully sort single cells of E-GFP expressing beta-cells.
Cutaneous Antigen Priming via Gene Gun Leads to Skin-Selective Th2 Immune-Inflammatory Responses (2005)

It is becoming increasingly evident that the compartmentalization of immune responses is governed, in part, by tissue-selective homing instructions imprinted during T cell differentiation. In the context of allergic diseases, the fact that "disease" primarily manifests in particular tissue sites, despite pervasive allergen exposure, supports this notion. However, whether the original site of Ag exposure distinctly privileges memory Th2 immune-inflammatory responses to the same site, while sparing remote tissue compartments, remains to be fully investigated. We examined whether skin-targeted delivery of plasmid DNA encoding OVA via gene-gun technology in mice could generate allergic sensitization and give rise to Th2 effector responses in the skin as well as in the lung upon subsequent Ag encounter. Our data show that cutaneous Ag priming induced OVA-specific serum IgE and IgG1, robust Th2-cytokine production, and late-phase cutaneous responses and systemic anaphylactic shock upon skin and systemic Ag recall, respectively. However, repeated respiratory exposure to aerosolized OVA failed to instigate airway inflammatory responses in cutaneous Ag-primed mice, but not in mice initially sensitized to OVA via the respiratory mucosa. Importantly, these contrasting airway memory responses correlated with the occurrence of Th2 differentiation events at anatomically separate sites: indeed cutaneous Ag priming resulted in Ag-specific proliferative responses and Th2 differentiation in skin-, but not thoracic-, draining lymph nodes. These data indicate that Ag exposure to the skin leads to Th2 differentiation within skin-draining lymph nodes and subsequent Th2 immunity that is selectively manifested in the skin.
