Using mandatory integrity to enforce 'commercial' security (2003)

Government research, development, and standardization efforts in computer security have been repeatedly criticized as not being applicable to the commercial world. In particular, they have been criticized as not being able to support the kinds of security policies, such as separation of duties and well-formed transactions, used by the financial and other communities to control unauthorized changes to or falsification of information. It is shown two natural extensions-integrity categories and partially trusted subjects-of the principles of current US Department of Defense computer security standards could be used to implement such commercial security policies in a way that exploits the fundamental strengths of existing or future trusted systems.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Recombinant human epidermal growth factor precursor is a glycosylated membrane protein with biological activity. (1989)

NIH 3T3 cells were transfected with cDNA corresponding to human kidney prepro-epidermal growth factor (preproEGF) under control of the inducible mouse metallothionein promoter. The synthesis of recombinant human EGF precursor by these cells has provided us with a model system for analysis of the structure and activity of this precursor. In transfected cells, the precursor was present as an intrinsic 170-kilodalton membrane protein as well as a soluble protein in the extracellular medium; both forms were N glycosylated. Glycosylation of the EGF precursor was determined by (i) the direct incorporation of [3H]mannose and [3H]glucosamine, (ii) metabolic labeling in the presence or absence of glycosylation inhibitors, (iii) enzymatic cleavage of the precursor by N-glycanase or endoglycosidase II, and (iv) lectin chromatography. Recombinant human preproEGF was purified by affinity chromatography, using wheat germ lectin and antibodies to human EGF. The intact precursor was biologically active. Purified preparations of preproEGF (i) competed with 125I-labeled EGF for binding to the EGF receptor in intact fibroblast cells, (ii) activated the intrinsic tyrosine kinase activity of the EGF receptor in membrane preparations, and (iii) sustained the growth of a mouse keratinocyte cell line that is dependent on EGF for growth. These results suggest that proteolytic processing of the precursor may not be essential for its biological function.
Kinetics of the reduction of chromium(VI) by vitamin C (2005)

Abstract The kinetics of the reduction of Cr(VI) to Cr(III) by vitamin C was studied using potassium dichromate solution as the model pollutant. Effects of the concentration of vitamin C, pH, temperature, and irradiation on the reduction of Cr(VI) were examined. The kinetics of Cr(VI) reduction by vitamin C can be described as -d[Cr(VI)]/dt = 0.0156 (μM s−1).[Cr(VI)][vitamin C] (pH 5), where dt is the differential function (d) of time (t). The activation entropy (ΔS‡) and enthalpy (ΔH‡) are 42.4 kJ mol−1 and -71.0 J mol−1 K−1, respectively, and the activation energy at 298 K is 63.5 kJ mol−1. The advantages of vitamin C as a reductant are as follows: It is an important biological reductant in humans and animals, and it is not toxic. Toxic Cr(VI) can be reduced by vitamin C not only in acidic conditions but also in alkaline solutions (pH 9); furthermore, the reduction was shown to occur both under the irradiation and in the dark. The present results suggest that vitamin C could be used effectively in the remediation of Cr(VI)-contaminated soil and groundwater in a wide range of pH, with or without sunlight.

Blue flower color development by anthocyanins: from chemical structure to cell physiology (2009)

Blue flower colors are primarily due to anthocyanin, a flavonoid pigment. Anthocyanin itself is purple in neutral aqueous solutions, ans its color is very unstable and quickly fades. Therefore, the mechanism of blue color development in living flower petals is one of the most intriguing problems in natural product chemistry. Much progress has been made in understanding blue flower coloration since the comprehensive review by Goto and Kondo in 1991. This review focuses on the advances in the last 15 years, and cites 149 references.

Growing Cholesterol-Dependent NS0 Myeloma Cell Line in the Wave Bioreactor System: Overcoming Cholesterol-Polymer Interaction by Using Pretreated Polymer or Inert Fluorinated Ethylene Propylene (2005)

Difficulty in growing cholesterol-dependent NS0 cells in the Wave bioreactor using the original low-density polypropylene (LDPE) bags has been encountered. It has been shown that in these bags chemically defined cholesterol is depleted from solution and therefore unavailable for the cells. Our data suggest that the cause of the depletion is not chemical but is due to the physical structure of the polymer. It is proposed that polymer structures with inkbottle pores retain cholesterol, whereas structures with V-shaped pores adsorb cholesterol reversibly. Ultra-low-density polyethylene (ULDPE) bags can support cell growth but need to be pretreated with excess cholesterol. Another material, fluorinated ethylene propylene (FEP) does not need to be pretreated and is found to be superior (negligible cholesterol adsorption) as a result of its inert characteristics.
A Vibrational Circular Dichroism Microsampling Accessory: Mapping Enhanced Vibrational Circular Dichroism in Amyloid Fibril Films (2017)

We report the first vibrational circular dichroism (VCD) measurement of spatial heterogeneity in a sample using infrared (IR) microsampling. Vibrational circular dichroism spectra are typically measured using a standard IR cell with an IR beam diameter of 10 mm or greater making it impossible to investigate the spatial heterogeneity of a solid film sample. We have constructed a VCD sampling assembly with either 3 mm or 1 mm spatial resolution. An XY-translation stage was used to measure spectra at different spatial locations producing IR and VCD maps of the sample. In addition, a rotating sample stage was employed using a dual photoelastic modulator (PEM) setup to suppress artifacts due to linear birefringence in solid-phase or film samples. Infrared and VCD mapping of an insulin fibril film has been carried out at both 3 and 1 mm spatial resolution, and lysozyme films were mapped at 1 mm resolution. The IR spectra of different spots vary in intensity due primarily to sample thickness. The changes in the VCD intensity across the map largely correlate to corresponding changes in the IR map. Closer inspection of the insulin map revealed changes in the relative intensities of the VCD spectra not present in the parent IR spectra, which indicated differences in the degree of supramolecular chirality of the fibrils in the various spatial regions. For lysozyme films, in addition to different degrees of supramolecular chirality, reversal of the net fibril chirality was observed. The large signal-to-noise ratio observed at 1 mm resolution implies the feasibility of further increasing the spatial resolution by one or two orders of magnitude for protein fibril film samples.

Terahertz emission from metal-organic chemical vapor deposition grown Fe:InGaAs using 830 nm to 1.55 μm excitation (2010)

We demonstrate the generation of broadband terahertz (THz) frequency radiation from photoconductive emitters formed from Fe-doped InGaAs (Fe:InGaAs), grown by metal-organic chemical vapor deposition, following pulsed (femtosecond) laser excitation at wavelengths ranging from 830 nm to 1.55 μm. The Fe is incorporated epitaxially during growth, giving precise control over the doping level. Using both single-crystal ZnTe and GaP electro-optic detectors over the same wavelength range, the emission spectra from several Fe:InGaAs wafers with different Fe content were measured, with THz emission from all wafers showing bandwidths in excess of 2.0 THz. The THz output power was found to be strongly dependant on the Fe content, the thickness of the Fe:InGaAs layer, and the excitation wavelength.
Service Level Management using QoS Monitoring, Diagnostics, and Adaptation for Networked Enterprise Systems (2006)

As enterprise services increasingly interconnect as networked services in a service-oriented architecture (SOA), service level management (SLM) is becoming a complex problem and can no longer be handled by traditional monitoring tools like Microsoft SMS. SLM is a process managing the quality of services demanded by clients and offered by providers. This paper presents two contributions to the research of SLM. First, instead of considering monitoring as an isolated service, it incorporates monitoring as an integral part of a comprehensive QoS management framework. This framework consists of QoS management concepts and services including service level contract management, admission control, resource management, monitoring, diagnostics, and adaptation. Using this framework, clients are able to negotiate quality of service contracts with providers and providers are able to optimize system resources to meet contract requirements. The second contribution is the incorporation of diagnostic service in the QoS management framework. Based on data feed from monitoring service, diagnostic service is able to detect any condition changes and to reason about the causes of any degradation conditions in the networked enterprise system. With condition detection and situation understanding, QoS management can then proactively activate adaptation mechanisms to maximize the system's ability to meet QoS contract requirements of concurrent clients. Our monitoring service uses both reporting approach and probing approach to acquire the information of the health status of elements of a networked system. The monitored data is then fed to our diagnostic service to reason about root causes of anomalies, using graphical models. Depending on the system health status and root causes, appropriate adaptations are triggered proactively to improve the system performance under the constraints of concurrent QoS contracts. We validate our SLM approach using QoS management services integrated in a publish/subscribe style of SOA. We then demonstrate via experiments some benefits of QoS monitoring, diagnostics, and adaptation services for responsiveness SLM.
Hamiltonian cycles in solid grid graphs (2002)

A grid graph is a finite node induced subgraph of the infinite two dimensional integer grid. A solid grid graph is a grid graph without holes. For general grid graphs, the Hamiltonian cycle problem is known to be NP complete. We give a polynomial time algorithm for the Hamiltonian cycle problem in solid grid graphs, resolving a longstanding open question posed by A. Itai et al. (1982). In fact, our algorithm can identify Hamiltonian cycles in quad quad graphs, a class of graphs that properly includes solid grid graphs.
On the Conductivity Produced in CdS Crystals by Irradiation with Gamma-Rays (1949)

By combining the theory of secondary photo-currents developed by Hilsch, Pohl, Schottky, and others, with the model of a crystal phosphor by Johnson and Seitz and by Riehl and Schoen a theory of the photo-conductivity in CdS crystals is given. The theory agrees qualitatively with the results of previous and present experiments. A quantitative energy scheme, which is the basis for this theory, has been determined from measurements of the emission and absorption spectra of these crystals. According to the new determined sign of the thermal e.m.f.: CdS against Cu, the photo-current in CdS is predominantly carried by electrons. The dark current follows the usual law: $log\ensuremath{\sigma}\ensuremath{\sim}\frac{1}{T}$ with the constants $\ensuremath{\epsilon}=0.67$ ev and ${\ensuremath{\sigma}}_{0}=1.7\ifmmode\cdot\else\textperiodcentered\fi{}{10}^{\ensuremath{-}3}$ mho ${\mathrm{cm}}^{\ensuremath{-}1}$. In accordance with the theory the final current reached after prolonged irradiation is proportional to the square root of the intensity of irradiation. The final current follows Ohms law. The initial slope of the decay curve is proportional to the intensity of irradiation. Under periodical irradiation with gamma-rays the amplitude of the resulting alternating current slowly increases to a final value. If the electric field is temporarily removed the original conductivity is slowly restored. When a CdS crystal is heated and then cooled to liquid air temperature irradiation produces a small primary current of less than ${10}^{\ensuremath{-}13}$ amp. at first. With continuous irradiation and after a slight delay this current suddenly increases until it reaches a constant value of ${10}^{\ensuremath{-}8}$ amp.

The average distance from the projection point of the lumbar pedicle axis to the midline of the transverse process consistently varied at different levels. This information may prove helpful in the placement of screws into the lumbar pedicle.
Microstructure and mechanical properties of Mg – Al9Zn/SiC<sub>p</sub>composite produced by vacuum stir casting process (2004)

15 vol.-% SiC particle reinforced cast Mg – 9AlZn (AZ91C) composite was produced by a vacuum stir casting process, and the microstructure and mechanical properties of the composite investigated. The stirring process was carried out at a speed of 750 – 1500 rev min-1 with a stainless steel impeller for 25 min in a vacuum of 20 – 40 mbar. SiC particles in the composite exhibited a reasonably homogeneous distribution and were well wetted by magnesium. The Mg – Al9Zn/15SiCp composite showed significant improvement in yield strength and elastic modulus following T4 heat treatment. The ultimate tensile strength of the composite was low, but close to that of unreinforced magnesium alloy. Mg/SiC interfacial reactions and reaction mechanisms are discussed. No evident interfacial products were found at a low process temperature of 700°C. However, significant chemical reactions at the Mg/SiC interface occurred when the composite melt was maintained at 750°C, and complex reaction products were formed. The fluidity of the composite melt deteriorated seriously after the interfacial reactions occurred.
Pulsed-current duty cycle dependence of electromigration-induced stress generation in aluminum conductors (1996)

The effect of duty cycle of pulsed dc currents on the critical length-current density product, (jl/sub c/), was measured using the Blech-Kinsbron edge-displacement technique [Thin Solid Films 25, 327 (1975)]. Unencapsulated Al edge-displacement segments mere stressed at various duty cycles and the critical lengths, the so-called "Blech lengths", were measured. It was found that jl/sub c/ increased with decreasing duty cycle. We measured a factor of 2.6 increase in jl/sub c/ for the 25% duty cycle as compared to dc. This duty cycle dependence of Blech length implies that electromigration resistance for an integrated circuit would be increased for small duty cycle operation by increasing the fraction of interconnects which are sub-Blech-length and are not susceptible to EM damage.
Upregulating Hif‐1α by Hydrogel Nanofibrous Scaffolds for Rapidly Recruiting Angiogenesis Relative Cells in Diabetic Wound (2016)

Nonhealing chronic wounds on foot are one of the most dreaded complications of diabetes, and biomedical scaffolds remain an attractive option for repairing or regenerating tissues. Accelerating angiogenesis in the early stage after injury is critical to wound healing process; however, the scaffolds accelerate the angiogenesis in the beginning but with the acceleration of vessel network formation the scaffold network hinders the process. In this study, the water soluble drugs-loaded hydrogel nanofibrous scaffolds are designed for rapidly recruiting angiogenesis relative cells and promoting wound healing. The sustained release profile of desferrioxamine (DFO), which continues for about 72 h, leads to significantly increase of neovascularization. The majority of the scaffold is degraded in 14 d, leaving enough space for cell proliferation and vessel formation. The in vitro results show that the scaffolds upregulate the expression of Hif-1α and vascular endothelial growth factor, and enhance the interaction between fibroblasts and endothelial cells. The in vivo studies show a higher expression of angiogenesis related cytokines. This study demonstrates that the DFO released from hydrogel nanofibrous scaffolds of quick degradation can interfere with the required prolyl-hydroxylases cofactors by acting as Fe(2+) chelator and upregulate the expression of Hif-1α, leading to a significant increase of the neovascularization.
Automatic Printing Equipment For Long Loaded Submarine Telegraph Cables (1927)

The introduction of the permalloy loaded submarine cable has presented the possibility of telegraph transmission at speeds several times those obtainable on non-loaded cables and has made practicable the operation of printer telegraph equipment. The present paper presents the various factors which affect the design of operating equipment and describes the apparatus which has been developed and used for a considerable period of time under service conditions. The transmission speed attained may exceed 2,400 letters per minute. To a certain extent, the detailed design of the terminal apparatus is controlled by the electrical characteristics of the particular cable to which it is to be applied and this type of equipment cannot, therefore, be completely standardized.
Layered corrugated electrode macrostructures boost microbial bioelectrocatalysis (2012)

The future success of microbial bioelectrochemical systems like microbial fuel cells inevitably depends on the increase of their performance at decreasing material costs. One of the key elements and a research priority is the biofuel cell anode. Here we propose layered corrugated carbon (LCC) as an inexpensive but high performance electrode material produced from the carbonization of one of the most abundant packing materials of our society: corrugated cardboard. In the base configuration of one corrugated layer the projected current density of LCC already reaches 70 A m−2. Increasing the number of corrugated layers increases the current density linearly. Thus, 200 A m−2 are achieved at three and 390 A m−2 at six corrugated layers. These current density values, which were confirmed by experiments in two independent laboratories, represent a performance increase of above one order of magnitude compared to the current state of research.
Implementing a RAKE receiver for wireless communications on an FPGA-based computer system (2000)

RAKE receivers are widely used in the wireless communications industry. Currently, custom VLSI is the most popular implementation. Programmable and reconfigurable logic implementations are becoming more attractive because of their flexibility and due to technology advancements. We have implemented a RAKE receiver on an Annapolis Wildforce board with four Xilinx 4000 family chips for a total of 100,000 gate equivalents. Our system is able to implement a RAKE receiver for underwater data communication systems that works in real time. We also investigate mapping a RAKE receiver to a Virtex chip for real-time atmospheric wireless communication.

Images resulting from highly undersampled existing k-space trajectories, such as EPI, Spiral, and Rosette, are greatly enhanced simply by adding a rotating nonlinear SEM field.
Functional hybrid materials based on carbon nanotubes and metal oxides (2010)

In this article, we discuss functional hybrid materials based on carbon nanotubes (CNTs) and metal oxides. The unique geometric nanostructure and electrical properties of CNTs significantly promote the dispersion of oxides with strong interaction. The improvement effect of CNTs on the performance of hybrid materials for supercapacitors, lithium ion batteries, electroanalysis and photocatalysis is addressed. The applications of CNT-oxide hybrid materials for solar cell and gas sensors are briefly introduced. The prospects and challenges for material science are also discussed.
