Fluorescence temperature measurements: Methodology for applications to process monitoring (2004)

Abstract In previous publications, we described a technique based on fluorescence spectroscopy to monitor resin temperature during processing. The method consists of using optical fiber sensors to monitor fluorescence from a fluorescent dye that has been doped into the processed resin. Temperature is derived from temperature‐induced changes in the fluorescence spectrum. In practice, a temperature calibration function is obtained from the temperature dependence of the ratio of fluorescence intensities at two wavelengths. In this paper, we address several experimental design issues: (a) the supportive role of fluorescence anisotropy measurements to the measuring concept, (b) the experimental setup used for noncontact measurements during capillary rheometry testing, and (c) molecular‐level environmental issues that arise during reactive processing and temperature profiling. We find that fluorescence anisotropy of the dye bis(2,5‐tert‐butylphenyl)‐3,4,9,10‐perylenedicarboximide (BTBP) is independent of shear rate up to 250 s −1 , implying that isotropic orientation of the dye is maintained as the matrix resin undergoes dynamic shear flow, i.e. the calibration function made under quiescent conditions applies to dynamic shear flow conditions. Using this technique in a noncontact application to monitor temperature of the extrudate from a capillary rheometer required an optical design that neutralized the focusing attributes of the cylindrical extrudate. Application to reactive processing is complicated by changes in polarization that accompany the reaction, and, in some cases, produce wavelength shifts in the fluorescence spectrum. We overcome these effects by using a dye that yields a calibration independent of the polarization effects and by averaging over a large dataset to reduce measurement uncertainty. Polym. Eng.

Lightweight encryption for email (2005)

Email encryption techniques have been available for more than a decade, yet none has been widely deployed. The problems of key generation, certification, and distribution have not been pragmatically addressed. We recently proposed a method for implementing a Lightweight Public Key Infrastructure (PKI) for email authentication using recent developments in identitybased cryptography and today’s existing Internet infrastructure. While this solution works well for email authentication, email encryption exhibits a different threat model that requires special treatment. In this work, we discuss how to achieve email encryption and present a realistic deployment and adoption process, while respecting the current functionality and expectations of email. 1
Characterization of a primary bile ductular cell culture from the livers of rats during extrahepatic cholestasis. (1985)

The establishment of novel bile ductular cell cultures was accomplished with the use of explants of a hyperplastic bile ductular tissue preparation obtained from rat livers at 10 to 15 weeks after bile duct ligation or a bile ductular cell fraction isolated from this tissue preparation by a procedure involving Percoll density gradient centrifugation. Observations made on these primary explant and monolayer bile ductular cell cultures were limited to the first 3 days of culture where the morphologic features of the bile ductular epithelium remained fairly well preserved, while fibroblast contamination was found to be very low. These cultured cells also retained over this period a high specific activity for the bile ductular cell marker enzyme gamma-glutamyl transpeptidase, as well as possessed measurable but decreasing specific activities for leucine aminopeptidase and alkaline phosphatase. Karyotypic analysis of the cultured monolayer cells further showed them to be diploid. In addition, preliminary transplantation studies demonstrated the presence of well-differentiated bile ductular-like structures following inoculation of the freshly isolated bile ductular cell fraction into the interscapular fat pads of recipient rats.
Gene therapy for chronic granulomatous disease (2004)

Chronic granulomatous disease (CGD) is a congenital immune deficiency that is a promising therapeutic target for gene replacement into haematopoietic stem cells (HSCs). CGD results from mutations in any one of four genes encoding subunits of the superoxide-generating NADPH oxidase of phagocytes. Life-threatening, recurrent bacterial and fungal infections, as well as inflammatory granulomas, are the hallmarks of the disease. NADPH oxidase activity can be reconstituted by retroviral- or lentiviral-mediated gene transfer to human CGD marrow in vitro and in xenograft transplant models. Gene transfer studies in knockout mouse models that resemble the human disease suggest that correction of oxidase activity in a minority of phagocytes will be of clinical benefit. Phase I clinical studies in unconditioned CGD patients showed transient expression of small numbers of gene-corrected neutrophils. Areas of research at present include efforts to enhance gene transfer rates into repopulating HSCs using vectors that transduce quiescent cells, and to increase the engraftment of genetically corrected HSCs using non-myeloablative conditioning and drug resistance genes for selection.
Proteins Specified by Herpes Simplex Virus, IV. Site of Glycosylation and Accumulation of Viral Membrane Proteins (1970)

The membrane glycoproteins specified by herpes simplex virus are synthesized concurrently with structural viral proteins and accumulate in the cytoplasm and in the membranes lining it. Analyses of free and membranebound polyribosomes, the cytoplasmic pool of soluble proteins, and purified smooth membranes showed that viral membrane proteins bind to membranes soon after synthesis and become glycosylated in situ .
Carbocyclic Nucleosides as Inhibitors of Human Tumor Necrosis Factor-α Production:  Effects of the Stereoisomers of (3-Hydroxycyclopentyl)adenines (1996)

A series of four structurally related carbocyclic nucleosides (6a, 6b, 10a, and 10b) were synthesized and evaluated for their ability to inhibit tumor necrosis factor-alpha (TNF-alpha), interleukin-1 beta (IL-1 beta), and interleukin-6 (IL-6) production from human primary macrophages. These compounds had little effect on the production of IL-1 beta and IL-6. It was determined that compound 10a was the most potent inhibitor of TNF-alpha production (IC50 = 10 microM), having 2-5-fold more activity compared to its enantiomer 10b or its diastereomers 6a and 6b. In addition, these compounds were also tested for their ability to protect mice against lethal challenges of lipopolysaccharide (LPS) and D-galactosamine (D-Gal). Compound 10a showed superior protective effects (100% protection) compared to its enantiomer 10b or its diastereomers 6a and 6b when it was administered to mice which were challenged with 3 times the LD100 dose of LPS.
A search for cataclysmic binaries containing strongly magnetic white dwarfs. (1982)

The AM Herculis type binaries which contain accreting white dwarfs with surface magnetic fields of a few times 10 to the seventh power gauss were studied. If white dwarfs in cataclysmic binaries have a range of field strengths similar to that among single white dwarfs. AM Her like systems should exist with fields as high as 3 x 10 to the eighth power gauss. It is suggested that such objects will not have the strong optical polarization of the AM Her variables; however, they exhibit high harmonic cyclotron emission, making them spectacular UV sources. We made IUE observations of seven candidate cataclysmic variables selected for optical similarity to AM Her binaries. Although all seven objects were detected in the UV, none display unusually strong UV continua. It is suggested that the distribution of magnetic field strengths among single white dwarfs may be different from that among binaries.
Asymptotic evaluation of the normalised cut-off frequencies of an optical waveguide with quadratic index variation (1977)

Asymptotic expressions for normalised cut-off frequencies of modes having large meridional order n and small azimuthal order m are obtained for an inhomogeneous waveguide having quadratic index variation. A fractional integral technique is used to construct solutions directly from the differential equation in the form of an integral representation, which is expanded by the steepest-descent procedure.
Hypoglycemia Rebound Migraine (2001)

Posthypoglycemic migraine may occur exceptionally in patients with unstable diabetes as a rebound phenomenon, caused by an unidentified mechanism.
Anesthetic Induction with Etomidate, Rather than Propofol, Is Associated with Increased 30-Day Mortality and Cardiovascular Morbidity After Noncardiac Surgery (2013)

Etomidate was associated with a substantially increased risk for 30-day mortality, cardiovascular morbidity, and prolonged hospital stay. Our conclusions, especially on 30-day mortality, are robust to a strong unmeasured binary confounding variable. Although our study showed only an association between etomidate use and worse patients' outcomes but not causal relationship, clinicians should use etomidate judiciously, considering that improved hemodynamic stability at induction may be accompanied by substantially worse longer-term outcomes.

A contextual-bandit approach to personalized news article recommendation (2010)

Personalized web services strive to adapt their services (advertisements, news articles, etc.) to individual users by making use of both content and user information. Despite a few recent advances, this problem remains challenging for at least two reasons. First, web service is featured with dynamically changing pools of content, rendering traditional collaborative filtering methods inapplicable. Second, the scale of most web services of practical interest calls for solutions that are both fast in learning and computation.
Comb-like Profiled Fiber Technologies for Synchronized Short Pulse Generation (2006)

Thermostable polynucleotide phosphorylases from Bacillus stearothermophilus and Thermus aquaticus (1976)

Polynucleotide phosphorylase from Bacillus stearothermophilus has been purified to homogeneity. Polyacrylamide gel electrophoresis run under denaturing conditions indicates that the enzyme is a tetramer with subunits of apparent molecular weight 51,000 daltons. A partial purification of polynucleotide phosphorylase from Thermus aquaticus has also been effected. The two enzymes show similar catalytic properties, which differ little from those of mesophilic polynucleotide phosphorylases. The use of thermostable polynucleotide phosphorylases for in vitro nucleic acid synthesis is discussed.
Expression, signaling proficiency, and stimulatory function of the NKG2D lymphocyte receptor in human cancer cells (2011)

The stimulatory natural killer group 2 member D (NKG2D) lymphocyte receptor and its tumor-associated ligands are important mediators in the immune surveillance of cancer. With advanced human tumors, however, persistent NKG2D ligand expression may favor tumor progression. We have found that cancer cells themselves express NKG2D in complex with the DNAX-activating protein 10 (DAP10) signaling adaptor. Triggering of NKG2D on ex vivo cancer cells or on tumor lines which express only few receptor complexes activates the oncogenic PI3K-protein kinase B (PKB/AKT)-mammalian target of rapamycin (mTOR) signaling axis and downstream effectors, the ribosomal protein S6 kinase 1 (S6K1) and the translation initiation factor 4E-binding protein 1 (4E-BP1). In addition, as in lymphocytes, NKG2D ligand engagement stimulates phosphorylation of JNK and ERK in MAP kinase cascades. Consistent with these signaling activities, above-threshold expression of NKG2D-DAP10 in a ligand-bearing tumor line increases its bioenergetic metabolism and proliferation, thus suggesting functional similarity between this immunoreceptor and tumor growth factor receptors. This relationship is supported by significant correlations between percentages of cancer cells that are positive for surface NKG2D and criteria of tumor progression. Hence, in a conceptual twist, these results suggest that tumor co-option of NKG2D immunoreceptor expression may complement the presence of its ligands for stimulation of tumor growth.
Foraminiferal assemblages from the late Lower and Middle Cenomanian of Speeton (North Yorkshire, UK): relationships with sea-level fluctuations and watermass distribution (1996)

Abstract. Twenty-seven marl samples from the late Lower and Middle Cenomanian of Speeton (North Yorkshire, UK) have been studied and six benthic foraminiferal assemblages (A to F) have been recognized by cluster analysis. These assemblages can be classified according to their constituent agglutinated foraminifera. Assemblages characterized by high abundances of non-calcareous agglutinates (A and E) have low numbers of planktics and are associated with cold-water pulse faunas of mid Russian affinity (belemnites, brachiopods and bivalves). These are interpreted as representing a cold North Sea watermass. Assemblages characterized by high abundances of planktics (B and C) are associated with pulse faunas that lack cold-water elements and are interpreted as representing a warm watermass. The foraminiferal assemblages are also related to sea-level fluctuations and individual assemblages were probably depth controlled. The assemblages can. therefore, be used to construct a sea-level curve and this agrees with the placement of critical sequence stratigraphic surfaces (e.g. sequence boundaries and flooding surfaces).

New results on fair multi-threaded paging. (1998)

The Multi-threaded Paging problem (MTP) was introduced as a generalization of Paging to the case where there are many threads of requests. This models situations in which the requests come from more than one independent source. At each step it is necessary to decide which request to serve among several possibilities, and also (as in normal Paging) which page of fast memory to remove on a page fault. In the fair version of the problem the algorithms must guarantee that the next request of each thread will be served within a predetermined finite time. In this paper we reduce the existing gaps between the known lower and upper bounds for the competitiveness of on-line algorithms for the fair version of MTP. We treat some particular situations, with finite and infinite input sequences. We prove higher lower bounds and present a new on-line algorithm. We close the gap for the case in which the cache can hold only one page; surprisingly, we obtain different bounds for even and odd number o...
Comparison of Hg<sub>0.6</sub>Cd<sub>0.4</sub>Te LPE layer growth from Te-, Hg-, and HgTe-rich solutions (1980)

For epitaxial layers grown from Te-rich solution at 500°C, the width of the graded composition region is 3 µm and the compositional variation across the layer and with depth into the layers is less than ±0.01 mole fraction CdTe. The graded composition region for layers grown from Hg-rich solution at 460°C is less than 3 µm; however, there is no uniform composition region because of CdTe depletion from the melt. The graded bandgap region for pseudobinary growth at 700°C is much wider (20 µm) than the other two cases; however, a region of uniform composition can be obtained by growing sufficiently thick layers (> 30 µm). Pseudobinary growth has the theoretical advantage that either p-type or n-type layers may be grown, whereas, only p-type layers may be grown from Te-rich solution at atmospheric pressure.
ADC and DSP challenges in the development of software radio base stations (1999)

The need for software-defined radios raises a number of technical challenges, which play a significant role in the development of third-generation personal communications systems (PCS). Some of the most important technical challenges deal with analog-to-digital conversion and digital signal processing technologies, which, in many cases, cannot provide the advanced hardware needed to support the demanding PCS telecommunications services. We discuss these two technical challenges, focusing primarily on base station radio systems. We first identify the most important requirements for ADC and DSP technologies, and we then extensively discuss and/or propose enabling schemes that could relax these requirements and aid the implementation of software radio base stations. Furthermore, we discuss new structures that can support the development of physically distributed base stations.
Plug Nozzle Flowfield Analysis (1997)

Results of numerical simulations of plug-nozzles are presented, and a phenomenological insight into the e owe eld development at different ambient pressures is given. Therefore, a e nite volume program using unstructured grids was adapted to the special boundary conditions of plug nozzles. Calculations were performed solving the Euler and Navier ‐ Stokes equations under ideal, perfect gas assumptions. Turbulence is taken into account with a k-e turbulence model. Numerical simulations are compared with experimental results of hot-run tests of a toroidal subscale model plug engine. Principal physical processes like expansion waves, compression shocks, and the recirculating base e ow region are in good agreement with available experimental data, and can therefore be predicted well. The simulations of a full-size plug nozzle, dee ned for a post Ariane 5 launcher, reveal a e owe eld behavior similar to the one observed with the toroidal subscale plug engine.

Frequency Offset Estimation for 5G Based LEO Satellite Communication Systems (2019)

The signal demodulation is significantly affected by the time-varying frequency offset in low earth orbit (LEO) satellite communication system. We present a method for Doppler shift and Doppler rate estimation based on 5G frame structure in satellite communication system. The integer and fractional part of the Doppler shift is estimated within a prime synchronizing signal (PSS) in two steps. Large estimation range and low complexity can be achieved in this method. Besides, a Doppler rate estimation algorithm is proposed. Precise Doppler rate is calculated by extracting the accumulated phase difference of two consecutive PSS. Furthermore, Kalman filter is utilized to improve the stability of the frequency offset estimators in low signal-to-noise ratio (SNR). Simulation results show that the estimators can perform well with large estimation range and high accuracy.
