The Purification of a GroEL‐Like Stress Protein from Aerobically Adapted <i>Campylobacter jejuni</i> (1995)

From plate cultures of Campylobacter jejuni grown in room air a particulate protein of 62 kDa was isolated by ion-exchange chromatography. The protein had a square shape from the side view but when viewed from the top it had a star-shaped structure. The molecular size of the whole particle determined by gel filtration was 850 kDa which suggested the presence of 14 subunits of 62 kDa in each particle. The N-terminal 37 amino residues showed more than 80% homology with the sequence of these heat shock protein (HSP) 60 homologs of Chlamydia trachomatis, Helicobacter pylori, and Escherichia coli (GroEL). This protein is immunologically cross-reactive with the antiserum for the 60-kDa HSP of Yersinia enterocolitica. Production of the 62-kDa protein increased under heat stress and growth in an aerobic atmospheric environment. From these observations we concluded that the 62-kDa protein is a Campylobacter stress protein (Cj62) which belongs to the HSP 60 family.
Joint MCMA and DD blind equalization algorithm with variable-step size (2009)

A variable step size technique is applied to joint modified constant modulus algorithm (MCMA) and decision-directed (DD) equalization algorithm to speed up convergence with respect to the original algorithm. The same technique is used with joint CMA and DD algorithm and exhibits improved performance.
A Dosage System for Use in the Treatment of Cancer of the Uterine Cervix (1938)

A dosage system expressed in terms of röntgens is proposed for the treatment of cancer of the uterine cervix. The anatomy of the part is considered in relation to spread of disease and to normal tissue tolerance. The vaginal and uterine applicators are described. Calculations are given to show how the dose may be balanced at selected points in the pelvis. The relation of such a system to the Paris and Stockholm techniques is discussed, and the Manchester technique for the study of maximum tolerance is described.
PDMS-Glass Interface Adhesion Energy Determined Via Comprehensive Solutions for Thin Film Bulge/Blister Tests (2010)

This paper provides comprehensive relationships for pressure, deflection, energy release rate, and phase angle for bulge testing, which are valid for all combinations of the testing length-scales (film thickness, debond size, and bulge height) and materials. These solutions can be used to design experiments that vary relative contributions of opening and sliding displacements at the crack tip by modulating the film thickness, debond size, and bulge volume. Their closed-form nature greatly facilitates property extraction via regression, e.g., modulus from experimental pressure/deflection data or interface toughness from debond size/injected volume data. This is illustrated using experiments to quantify the interfacial adhesion energy between an initially dry polydimethylsiloxane-glass interface via bulge testing under controlled volume injection. The results indicate that the mode-mixity has no effect on the energy required for debonding, which suggests that wetting of the crack faces behind the debonding front eliminates friction.
Three-dimensional structure of the T-layer of Bacillus sphaericus P-1 (1986)

The three-dimensional structure of the regular surface layer of Bacillus sphaericus P-1 (T-layer) was determined to a resolution of ca. 2.5 nm by electron microscopy and image analysis. The T-layer has P4 symmetry, a lattice constant of 13 +/- 0.2 nm, and a thickness of ca. 8 nm. The reconstruction revealed three distinct domains: a major, a minor, and an arm domain. In the z-direction, the domains are arranged in two planes creating two different surface reliefs.
Distributed PKG ID based signcryption (2011)

An identity-based signature scheme allows any pair of users to communicate securely and to verify each other's signatures without exchanging public key certificates. For achieving both confidentiality and authenticity simultaneously, signcryption schemes are used. This paper puts forward a new efficient construction for signcryption scheme which is based on inverse bilinear Diffie Hellman problem and Discrete Logarithmic problem. The proposed scheme is secure against chosen ciphertext attack and has least complexity in terms of computational complexity as compared to earlier proposed schemes. The proposed scheme also caters the inherent problem of Key Escrow where private key generator (PKG) is not trusted by the use of concept of distributed PKG.
A Novel Scheme for Realization of Flexible ODU Hitless Resizing (2010)

Flexible optical channel data unit (ODUflex) is a new technique in the optical transport network (OTN) used to replace virtual concatenation (VCAT). For packet clients, it will be advantageous while ODUflex has the capability of hitless resizing like link capacity adjustment scheme (LCAS). A novel scheme is proposed in the paper for this purpose. The proposed scheme designs the new overhead (OH) and new protocol to achieve ODUflex hitless resizing. Moreover, it can be easily implemented in practical application.

Dynamics of gain-switched Cr:YAG lasers (1998)

An investigation of the influence of pump and laser excited state absorption (ESA), parasitic losses and pump parameters on Cr:YAG laser action has been carried out. A simple rate equation model has been extended to include ESA and dynamic pump effects. Results are compared with those obtained using a full spatio-temporal gain-switching model, and with experimental measurements in three temporal regimes. Comparison allows values for quantum efficiency and laser absorption, emission and ESA cross-sections to be allocated within the wide range of previously published data. Remaining discrepancies are attributed to thermal loading. An optimum pump energy is determined for a given fluence, and effective Cr:YAG energy scaling is demonstrated with only a slight threshold increase. Further enhancement is obtained using 500 ns pump pulses.
All-fiber grating-based higher order mode dispersion compensator for broad-band compensation and 1000-km transmission at 40 Gb/s (2001)

We use a novel fiber-grating device to demonstrate the first polarization-insensitive all-fiber higher order mode dispersion compensator for broad-band dispersion compensation. Its low loss and high effective area have enabled transmission through 1000 km (10/spl times/100 km) of nonzero dispersion-shifted fiber (NZDSF) at 40 Gb/s.

Enteral absorption in man of eicosapentaenoic acid in different chemical forms (1987)

After administering the equivalent of 1 g of eicosapentaenoic acid (EPA) in four different chemical forms, the kinetics of EPA incorporation into plasma triglycerides (TG) were compared by gas liquid chromatography on a capillary column following separation of the lipid fraction by thin layer chromatography. EPA incorporation into plasma TG was markedly smaller and later when EPA was administered as an ethyl ester rather than as EPA free fatty acid, EPA arginine salt or 1,3-dioctanoyl-2-eicosapentaenoyl glycerol (2-EPA). Our results and the data in the literature are compatible with the hypothesis that 2-EPA is absorbed with minimum hydrolysis and escapes random distribution between the other positions of the glycerol molecule during the absorption process.
Assembler utility functions for APL2/PC (1991)

Some general guidelines are discussed on why and how to develop utility functions in assembler for the APL2/PC environment. Assembler utility functions may replace some most heavily used idiomatic APL auxiliary functions and boost the efficiency of APL applications. About twenty such functions are presented, some of them perhaps useful as temporary extensions of the APL2/PC interpreter. The collection of assembler utility functions is available in the public domain, and should be extended by the joint efforts of the international APL community.
PAM: An Efficient Power-Aware Multi-level Cache Policy to Reduce Energy Consumption of Software Defined Network (2015)

Nowadays energy consumption is one of the most significant aspects in Internet operations, where multi-level routing is widely used. In a typical hierarchical router cache structure, the upper level storage serves as a cache for the lower level, which forms a distributed multi-level cache system. In

Permeability testing of composite material and adhesive bonds for the DC-XA composite feedline program (1995)

Hercules IM7/8552 carbon/epoxy and Hysol EA 9394 epoxy adhesive bonded between composite/titanium were tested for permeability after various numbers of thermal cycles between 100 C and liquid nitrogen (-196 C). The specimens were quenched from the 100 C temperature into liquid nitrogen to induce thermal shock into the material. Results showed that the carbon/epoxy system was practically impermeable even after 12 thermal cycles. The EA 9394 adhesive bondline was more permeable than the carbon/epoxy, but vacuum mixing minimized the permeability and kept it within allowable limits. Thermal cycling had little effect on the permeability values of the bondline specimens.
A Celebration of the 100th Anniversary of Chi-Hun Cho’s Birth (2021)

In 2021, the 100th anniversary celebration of the birth of the Korean poet Chi-Hun Cho took place in Korea University. As a member of the Blue Deer School (Cheong-rok pa), Chi-Hun Cho left behind many poetic masterpieces. His poetry is widely recognized as expressing the spirit of Korean nationalism. Cho’s students and other literary society members commemorated his death with recitations of his works of poetry. In order to achieve such honor and respect, the literary person must live a life that is in agreement with the words and themes of their work. Cho was one of those honorable people, as he lived as a man with such a philosophy and a warm heart. As we live in an era when humanity and morality seem to be vanishing, we honor and celebrate the life of Cho, who has had such a great influence on the history of Korean literature.
Rumination and activity levels as predictors of calving for dairy cows (2014)

The Australian dairy herd size has doubled over the last 20 years substantially increasing the time that farmers require for individual animal attention to monitor and intervene with events such as calving. Technology will help focus this limited labour resource on individual cows that require assistance. The objective of this experiment was to first determine the profiles of rumination duration and level of activity as determined by sensors between, and within, days around calving and second to use these data to predict the day of calving for pasture-based dairy cows. After 2 weeks from the expected calving date, 27 cows were fitted with SCR HR LD Tags, located in 40×90 m2 paddock and offered ad libitum oaten hay and 2 kg grain-based concentrate/cow per day until calving. Hourly activity and rumination data for each cow, as determined by the SCR tags, were fitted with linear mixed models and all parameters were estimated using restricted maximum likelihood. Rumination duration decreased by 33% over the day prior and the day of calving, with the decline in rumination duration starting the day prepartum. Activity levels were maintained prepartum but increased in the days postpartum. The day of calving was recorded and used to determine the gold standard positive (the day before calving) and negative (all other) dates. A threshold rumination level of 0.9 (decline in rumination duration of 10%) gave the optimal combination of 70% sensitivity and 70% specificity. This experiment shows the potential to use rumination duration to predict the day of calving and the opportunity to use sensor data to monitor animal health.
Development of Candidate Rotavirus Vaccines Derived from Neonatal Strains in India (2005)

The need for a rotavirus vaccine in India is based on the enormous burden associated with the >100,000 deaths due to rotavirus diarrhea that occur annually among Indian children. Two rotavirus strains identified during nosocomial outbreaks of rotavirus infection in New Delhi and Bangalore, India, more than a decade ago are being developed as live oral vaccines. Infected newborns had no symptoms, shed virus for up to 2 weeks after infection, mounted a robust immune response, and demonstrated protection against severe rotavirus diarrhea after reinfection. The 2 strains are naturally occurring bovine-human reassortants. The New Delhi strain, 116E, is characterized as having a P[11],G9 genotype, and the Bangalore strain, I321, is characterized as having a P[11],G10 genotype. The strains have been prepared as pilot lots for clinical trials to be conducted in New Delhi. This unique project, which is developing a new rotavirus vaccine in India with the use of Indian strains, an Indian manufacturer, and an Indian clinical development program, aims to expedite introduction of rotavirus vaccines in India.
SUMMARY REPORT ON INVESTIGATION OF MINIATURE VALVELESS PULSEJETS (1964)

Eleven sizes and configurations of miniature valveless pulsejets were built and tested to determine performance and operational characteristics and to support this report on the general state of the art. When combined with ejector type intermittent jet thrust augmenters, the best performance was achieved with the HH-Ml pulsejet with augmenters, which produced 17 lb thrust with a Tsfc of 1.8 and a thrust augmentation ratio of 1.9. Thrust-to-combustor volume ratio for this basic pulsejet was 140 lb/cubic foot. With augmenters and enclosing shroud, the complete engine package would produce 20 lb/cubic foot. Thrust-to- weight ratios approached 12 to 1. Advantages of simplicity, low cost, and high combustion efficiency and heat transfer rates due to unsteady flow, make these engines well suited for heater-blower applications as well as having some potential for thrust applications.

Two-Step Stimulation of B Lymphocytes to Enter DNA Synthesis: Synergy Between Anti-Immunoglobulin Antibody and Cytochalasin on Expression of c- <i>myc</i> and a G <sub>1</sub> -Specific Gene (1988)

Previously we demonstrated that stimulation of resting murine splenic B lymphocytes with goat anti-mouse immunoglobulin antibody (GaMIg) plus cytochalasin D (CD) led to DNA synthesis; GaMIg and CD added simultaneously, or GaMIg added before CD, induced this response (T. L. Rothstein, J. Immunol. 136:813-816, 1986). Cells similarly treated with GaMIg or CD alone did not enter S phase. Here we have measured the effects of this two-signal stimulation on the c-myc, 2F1, and gamma-actin genes. The expression of these growth-related genes is known to change either during the G0-to-G1 transition or in the G1 phase of the cell cycle. For the 2F1 and c-myc genes, neither the GaMIg nor CD stimulus alone led to a prolonged increase in mRNA levels, whereas GaMIg plus CD allowed for continuous elevated expression of these genes. Furthermore, GaMIg pretreatment rendered expression of the c-myc and 2F1 genes susceptible to subsequent action by CD. In contrast, CD alone was sufficient to produce changes in gamma-actin gene expression. Thus there are synergistic effects of competence- and progressionlike factors on the expression of the c-myc and 2F1 genes, and these effects correlate with the progression of B lymphocytes to DNA synthesis.
Analysis of soliton stability and interactions with sliding filters (1994)

We study the mechanism of separation of solitons from radiation in a periodically amplified fiber link with sliding filters. We also present a two-soliton perturbation analysis that explains the suppression of soliton interactions by sliding filters.
The diagnosis and evaluation of dementia and mild cognitive impairment with emphasis on SPECT perfusion neuroimaging (2012)

As the world population ages, the incidence of dementing illnesses will dramatically increase. The number of people afflicted with dementia is expected to quadruple in the next 50 years. Since the neuropathology of the dementias precedes clinical symptoms often by several years, earlier detection and intervention could be key steps to mitigating the progression and burden of these diseases. This review will explore methods of evaluating, differentiating, and diagnosing the multiple forms of dementia. Particular emphasis will be placed on the diagnosis of mild cognitive impairment-the precursor to dementia. Anatomical imaging; cerebrospinal fluid markers; functional neuroimaging, such as positron emission tomography and single photon emission tomography; and molecular imaging, such as amyloid marker imaging, will be assessed in terms of sensitivity and specificity. Cost will also be a consideration, as the growing population afflicted with dementia represents an increasingly large financial encumbrance to the healthcare systems of every nation. In the face of expensive new markers and limited availability of cyclotrons, single photon emission computer tomography (SPECT) provides relatively high sensitivity and specificity at a comparatively low overall cost.
Purification and characterization of endoglucanase C from <i>Clostridium cellulolyticum</i> (1993)

An Escherichia coli clone was constructed to overproduce endoglucanase C (CelCCC) from Clostridium cellulolyticum. This construction made it easier to isolate the enzyme but, as observed in the case of endoglucanase A (CelCCA) from the same organism, the purification led to the isolation of two forms of the cellulase differing in their molecular masses, 48 kDa and 41 kDa. N-terminal sequence analysis of both purified enzymes showed that the shorter form was probably the result of partial proteolysis near the COOH-extremity. The difference in mass indicated that the shorter protein lacks the C-terminal reiterated domains (20-24-amino-acid twice-repeated sequences). These particular domains are characteristic of clostridial cellulases acting on cellulose by the mean of cellulosomal particles. Biochemical and enzymic studies were performed on each form of CelCCC, and revealed that their temperature and pH optima were identical, but their catalytic parameters were quite different. Furthermore, the differences of enzymic behavior observed between the two forms of CelCCC are almost identical to those already noted in the case of the two forms of CelCCA. The stereoselectivity of the reaction catalysed by CelCCC and CelCCA was determined using proton NMR spectroscopy; CelCCC acts by configuration inversion, whereas CelCCA acts by configuration retention. The degradation patterns on cellodextrins (ranging from cellotriose to cellohexaose) and chromophoric cellodextrins (from p-nitrophenyl-cellobiose to p-nitrophenyl-cellopentaose) were also investigated in both forms of CelCCC and CelCCA. It emerged that the natural cellodextrins degradation patterns of CelCCC and CelCCA were very similar but the utilization of p-nitrophenyl-cellodextrins showed the existence of considerable differences between these two endoglucanases in terms of cleavage-site position and catalytic parameters. CelCCC and CelCCA were found not to act synergistically on the tested substrates.
A Miniature Flow Cell Designed for Rapid Exchange of Media Under High-power Microscope Objectives (1984)

The design, fabrication and use of a flow cell that allows rapid displacement of media viewed by short working distance, high power objectives are described. The cell has a small internal depth (about 0.04 cm), small volume (about 0.05 ml), and is chemically inert. It has been tested extensively in studies of tethered bacteria.
New anticancer agents in clinical development. (1995)

A better understanding of the biology and biochemistry of the cancer cell has led to the development of various promising new antineoplastic compounds that are now undergoing phase I, II, and III clinical testing. These drugs include topoisomerase I inhibitors, such as camptothecin and its analogs 9-aminocamptothecin, irinotecan, and topotecan; and the paclitaxel analog docetaxel. The authors discussed these new agents last month. In Part 2 of their article, they describe gemcitabine, an antimetabolite structurally related to cytarabine; fluorouracil prodrugs and other thymidylate synthase (TS) inhibitors, and new approaches to anticancer therapy, such as angiogenesis inhibitors, differentiating agents, signal transduction inhibitors, and gene therapy.
