Nonintrusive Cloning Garbage Collection with Stock Operating System Support (1997)

It is well accepted that automatic garbage collection simplifies programming, promotes modularity, and reduces development effort. However it is commonly believed that these advantages do not counteract the perceived price: excessive overheads, possible long pause times while garbage collections occur, and the need to modify existing code. Even though there are publically available garbage collector implementations that can be used in existing programs, they do not guarantee short pauses, and some modification of the application using them is still required. In this paper we describe a snapshot-at-beginning concurrent garbage collector algorithm and its implementation. This algorithm guarantees short pauses, and can be easily implemented on stock UNIX-like operating systems. Our results show that our collector performs comparable to other garbage collection implementations on uniprocessor machines and outperforms similar collectors on multiprocessor machines. We also show our collector to be competitive in performance with explicit deallocation. Our collector has the added advantage of being non-intrusive. Using a dynamic linking technique and effective root set inferencing, we have been able to successfully run our collector even in commercial programs where only the binary executable and no source code is available. In this paper we describe our algorithm, its implementation, and provide both an algorithmic and a performance comparison between our collector and other similar garbage collectors. ©1997 by John Wiley & Sons, Ltd.
Using profiled ontologies to leverage model driven user interface generation (2015)

Mobile computing and new input methods have increased the need to create multiple interfaces for one functional core. Automatic generation of user interfaces attempts a solution for this problem. Existing approaches either generate interfaces on the base of a detailed task model or use domain models in conjunction with interface specific annotations and transformation rules. While task models are very time consuming to create and cannot easily be reused domain models lack the flexibility for use cases which are not covered or in conflict with used transformation rules. Based on an overview of existing approaches this paper sets out a conceptual framework which combines both task model and ontology based concepts. It is shown that the proposed combination leads to more abstract and reusable task models.
<title>Distributed large data-object management architecture</title> (1997)

We are exploring the use of highly distributed computing and storage architectures to provide all aspects of collecting, storing, analyzing, and accessing large data-objects. These data-objects can be anywhere from tens of MBytes to tens of GBytes in size. Examples are: single large images from electron microscopes, video images such as cardio- angiography, sets of related images such as MRI data and images and numerical data such as the output from a particle accelerator-experiment. The sources of such data objects are often remote from the users of the data and from available large-scale storage and computation systems. Our Large Data- object Management system provides network interface between the object sources, the data management system and the user of the data. As the data is being stored, a cataloguing system automatically creates and stores condensed versions of the data, textual metadata and pointers to the original data. The catalogue system provides a Web based graphical interface to the data. The user is able the view the low- resolution data with a standard internet connection and Web browser, or if high-resolution is required can use a high- speed connection and special application programs to view the high-resolution original data.
Nanocrystalline Cu2O prepared under high pressures (2002)

The effect of high pressure on the structure of Cu2O is investigated. Polycrystalline samples are treated during different periods of time at different temperatures and pressures in the vicinity of the kinetic curve of the decomposition Cu2O → Cu+CuO. The structure of the samples subjected to thermobaric treatment is characterized by x-ray diffraction, electron diffraction structural analysis, and electron microscopy at atmospheric pressure. It is found that, upon treatment of Cu2O at temperatures and pressures close to the decomposition region, the microstructure undergoes a transformation into the nanocrystalline state.
An Energy Harvesting Underwater Acoustic Transmitter for Aquatic Animals (2016)

Acoustic telemetry is the primary method to actively track aquatic animals for behavioral studies. However, the small storage capacities of the batteries used in the transmitters limit the time that the implanted animals can be studied. In this research, we developed and implemented a battery-free acoustic transmitter that uses a flexible piezoelectric beam to harvest energy from fish swimming as the power source. The transmitter sends out a unique identification code with a sufficiently strong signal (150 dB, ref: 1 μPa at 1 meter) that has a detection range of up to 100 meters. Two prototypes, 100 mm and 77 mm long, respectively, weighing only about 1 gram or less in air, were sub-dermally implanted in two species of live fish. Transmissions were successfully detected as the fish swam in a natural manner. This represents the first known implanted energy-harvesting transmitter demonstrated in vivo. Successful development of this transmitter greatly expands the potential for long-term studies of the behaviors of aquatic animals and for subsequently developing strategies to mitigate the environmental impacts of renewable energy systems.

In summary, plateletpheresis is suited to provide PRP products with higher concentrations of human platelets and platelet-derived growth factors than previously reported PRP preparation methods but with extremely low numbers of contaminating leucocytes.
Fundamentals of chemical purification of detonation nanodiamond soot using nitric acid (2008)

The paper addresses the chemical purification behavior of detonation nanodiamond soot in the case of using a dilute nitric acid under pressure. The optimal process is found to proceed at 230–240°C, 7–8 MPa, with HNO3 excess of 200–300% of stoichiometry.
<title>Near-IR (800 to 855 nm) sensitive holographic photopolymer-dispersed liquid crystal materials</title> (1999)

H-PDLC materials are introduced with sensitivity in the 800- 850 nm region. Materials presented are based on acrylate monomers mixed with liquid crystalline (LC) compounds and sensitized to near IR. This allows highly efficient in-situ recording of holographic optical elements by diode lasers. Various LC compounds have been tested, in particular: E7, 5CB, MBBA. The following parameters of the H-PDLC materials and the recorded gratings were investigated: sensitivity of the materials in the range 800-850 nm, diffraction efficiency in a wide range of wavelengths and photochemical stability of the recorded gratings. The sensitivity of the materials with LCs E7 and 5CB was found to be ca. 300-500 mJ/cm<SUP>2</SUP> to wavelengths 834 and 850 nm. Employment of MBBA led to drop in sensitivity of about an order of magnitude. High diffraction efficiency was demonstrated. Particularly interesting are the following properties of our materials: (1) Control of the dispersion of the diffraction efficiency for p-polarization is shown to be possible by changing the monomer content of the formulations. (2) Recorded gratings exhibit excellent photochemical stability. (3) Switching of the gratings is in principle possible and currently worked on.
A Two Dimensional Tunneling Resistance Transmission Line Model for Nanoscale Parallel Electrical Contacts (2019)

Contact resistance and current crowding are important to nanoscale electrical contacts. In this paper, we present a self-consistent model to characterize partially overlapped parallel contacts with varying specific contact resistivity along the contact length. For parallel tunneling contacts formed between contacting members separated by a thin insulating gap, we examine the local voltage-dependent variation of potential barrier height and tunneling current along the contact length, by solving the lumped circuit transmission line model (TLM) equations coupled with the tunneling current self consistently. The current and voltage distribution along the parallel tunneling contacts and their overall contact resistance are analyzed in detail, for various input voltage, electrical contact dimension, and material properties (i.e. work function, sheet resistance of the contact members, and permittivity of the insulating layer). It is found the existing one-dimensional (1D) tunneling junction models become less reliable when the tunneling layer thickness becomes smaller or the applied voltage becomes larger. In these regimes, the proposed self-consistent model may provide a more accurate evaluation of the parallel tunneling contacts. For the special case of constant ohmic specific contact resistivity along the contact length, our theory has been spot-checked with finite element method (FEM) based numerical simulations. This work provides insights on the design, and potential engineering, of nanoscale electrical contacts with controlled current distribution and contact resistance via engineered spatially varying contact layer properties and geometry.
Quality of life in elderly patients with acute myeloid leukemia: patients may be more accurate than physicians (2011)

Quality of life could have an important role in elderly acute myeloid leukemia patients at diagnosis as a prognostic factor for survival and a potential factor for treatment decisions.
Evaluating instruction cache vulnerability to transient errors (2007)

Recent research shows that microprocessors are increasingly susceptible to transient errors. In order to protect microprocessors cost-effectively, the first step is to accurately understand the impact of transient errors on the system reliability. While many research efforts have been focused on studying the vulnerability of data caches and other on-chip hardware components, instruction caches have received less attention. However, instructions are read every cycle, any undetected or uncorrected soft errors in instructions can lead to erroneous computation, wrong control flow or system crash. This paper studies the instruction cache vulnerability by considering both the raw SRAM rate and the cache vulnerability factor. Based on the concept of cache vulnerability factor, we also investigate the impact of different cache configuration parameters on the reliability of instruction caches. We find that on average 67.5% of instruction cache soft errors can be masked by the I-cache itself without impacting other system components. While quantifying the instruction cache vulnerability itself does not solve the reliability problem of instruction cache against transient errors, we believe this work can provide useful insights for designers to develop cost-effective solutions to protect I-caches and to optimally balance the reliability of instruction caches with other system goals, such as cost, performance and energy.
Evolutionary migration of legacy systems to an object-based distributed environment (1999)

There is an increasing interest in migrating legacy systems to new hardware platforms and to new software development paradigms. High maintenance costs and lack of documentation are among the challenges facing software engineers who wish to migrate such systems. The increasing emphasis on distributed systems and on the object-oriented paradigm suggests that object-oriented, component-based, distributed systems will represent a significant portion of the next generation of software systems. We present a semiautomatic, evolutionary migration methodology for legacy systems which produces an object-based distributed system. We use ISA which is a design recovery and subsystem classification technique that produces a data-cohesive hierarchical subsystem decomposition of the subject system. We adapt the subsystems to the object-oriented paradigm. We wrap and define interfaces of the subsystems in order to define components. Components are allocated to multiple sites. Finally, middleware technologies for distributed systems are used to implement the communication between components. The approach is suitable for the evolutionary migration of legacy systems since each component can be reengineered separately.

STARNET: a multi-gigabit-per-second optical LAN utilizing a passive WDM star (1993)

We propose a new broad-band local area network, STARNET, based on a physical passive star topology. Over a single physical network, STARNET offers all users both a moderate-speed packet network and a high-speed WDM circuit interconnect. Based on these two data transport facilities, several topological aDd protocol solutions are available to the users. As a result, STARNET supports traffic of widely different speed and continuity characteristics. Each node of the network requires only two lasers and its structure facilitates the achievement of frequency stabilization for the whole network. An effort toward an experimental demonstration of a 3 Gb/s per node, FDDI-compatible (at the packet network level) STARNET is currently in progress at the Optical Communication Research laboratory of Stanford University
Energy efficient rate coverage with base station switching and load sharing in cellular networks (2016)

During low user demand, significant energy can be saved in a cellular network by using base station switching (BSS). However, coverage restrictions limit the number of base stations (BSs) a cellular operator can turn off. In this work, we examine the scenario when multiple cellular operators cooperate by sharing the load of their users with BSS (for example, on weekends). We show that significantly more energy can be saved by performing BSS with load sharing between the cellular operators. We formulate this cooperative BSS as an optimization problem. Further, for suitable service level agreements between the cellular operators, we show that the proposed optimization problem is real time solvable. Finally, we present results that quantify the achievable gains obtained by BSS with cooperation among the cellular operators. We also present the rate and coverage trade-off results which can be used by the cooperative cellular operators to find suitable points of operation.
DC microgrid based distribution power generation system (2004)

This paper describes an autonomous-control method for a DC microgrid system having distribution power generators. This system consists of following five generation and control units; a solar-cell generation unit, a wind-turbine generation unit, a battery energy-storage unit, a flywheel power-leveling unit, and an AC grid-connected power control unit. The proposed control method intended for suppression of circulating current detects only the DC grid voltage. Each unit could be controlled autonomously without communicating each other. This method brings high reliability, high-flexibility and maintenance-free operation to the system. Experimental results from a 10 kW-prototype system verify the validity and effectiveness of the proposed control method.
Tandem mass spectrometry identifies sites of three post-translational modifications of spinach light-harvesting chlorophyll protein II. Proteolytic cleavage, acetylation, and phosphorylation. (1991)

The photosynthetic membranes of spinach (Spinacia oleracea L.) chloroplasts were incubated with [gamma-32P] ATP. When the thylakoid membrane kinase was activated with light, the 25- and 27-kDa forms of the light-harvesting chlorophyll a/b protein (LHC II) were phosphorylated on their amino termini. Treatment of the membranes with proteinase K or thermolysin released phosphopeptides which were purified by ferric ion affinity chromatography and reverse phase high performance liquid chromatography. Sequencing of the phosphopeptides was performed with tandem quadrupole mass spectrometry. Three different phosphopeptides Ac-RKTAGKPKT, Ac-RKTAGKPKN, and Ac-RKSAGKPKN originating from class I LHC II were examined after release by thermolysin. One phosphopeptide, Ac-RRTVKSAPQ, originating from class II LHC II was examined after release by proteinase K. Each of the four LHC II phosphopeptides was derived from the amino terminus of a distinct protein. Peptides were acetylated at their amino-terminal arginine and were phosphorylated on either threonine or serine in the third position. We conclude that proteolytic processing of pre-LHC II occurs at a conserved methionyl-arginyl bond and is followed by amino-terminal acetylation of the arginine and nearby phosphorylation of the mature LHC II. Eight different peptides were synthesized in acetylated and nonacetylated forms as substrates for the thylakoid membrane kinase. From a comparison of the kinetics of phosphate incorporation into the peptides, we conclude that basic residues on both sides of the phosphorylation site are important for enzyme recognition. Acetylation of the amino terminus is not required for phosphorylation.
Efficiency measurement and uncertainty discussion of an electric engine powered by a “self-breathing” and “self-humidified” proton exchange membrane fuel cell (2007)

The efficiency of an automotive engine based on a "self-breathing" and "self-humidified" proton exchange membrane fuel cell stack (PEM FC) connected to a dc brushless electrical motor was measured under variable power load conditions. Experiments have been carried out on a small scale 150 W engine model. After determining the fuel cell static polarization curve and the time response to power steps, the system was driven to copy on the test bench a "standard urban load cycle" and its instantaneous efficiencies were measured at an acquisition rate of 5 Hz. The integral system efficiency over the entire urban load cycle, comprising the losses of the unavoidable auxiliary components of the engine, was then calculated. The fuel cell stack was operated mainly in "partial" dead-end mode, with a periodic anode flow channel purging, and one test was carried out in "pure" dead-end mode, with no anode channel purging. An uncertainty analysis of the efficiencies was carried out, taking into account either type A and type B evaluation methods, strengthening the discussion about the outcomes obtained for a system based on this novel simplified FC type. For our small scale engine we measured over the standard urban cycle, on the basis of the H(2) high heating value (HHV), a tank-to-wheel integral efficiency of (18.2+/-0.8)%, when the fuel cell was operated with periodic flow channel purging, and of (21.5+/-1.3)% in complete dead-end operation mode.
The Pmel 17/silver locus protein. Characterization and investigation of its melanogenic function. (1994)

The silver mutation in mice causes progressive graying of hair due to the loss of functional follicular melanocytes. Recently the silver locus gene (called Pmel 17) has been cloned; its encoded product shares homology with a chick melanosomal matrix protein and a bovine retinal pigment epithelial protein. Although the sequence of the silver gene and the correlation of its expression with pigment production have been reported, its function in melanogenesis is still unknown. In an effort to characterize that function, we have synthesized the predicted carboxyl-terminal peptide of the mouse Pmel 17 protein and generated a rabbit polyclonal antibody (alpha PEP13) to it; that antibody recognized the silver protein specifically. The immunoaffinity-purified silver protein lacked all of the known melanogenic catalytic activities which other tyrosinase-related proteins (TRP) have, nor did it appear to modulate any of those TRP activities. Metabolic labeling experiments demonstrated that the silver protein disappears in vivo within a few hours, indicating that it is rapidly degraded, or quickly processed to lose its carboxyl terminus. Cross-reactivity experiments showed that a recently reported anti-melanosomal matrix protein antibody (alpha MX) also recognizes the silver protein, although at a different epitope from that of alpha PEP13. Using Western immunoblotting, we analyzed subcellular fractions isolated from B16 F10 melanoma cells and found that the silver protein was rich in the melanosome fraction but was absent from coated vesicles which deliver TRPs to melanosomes. These results suggest that the silver locus product is a melanosomal matrix protein which may contribute to melanogenesis as a structural protein, although the possibility remains that it also has a novel catalytic function in melanogenesis.

Nutraceuticals for Skin Care: A Comprehensive Review of Human Clinical Studies (2018)

The skin is the body's largest organ, it participates in sensitivity and offers protection against microorganisms, chemicals and ultraviolet (UV) radiation. Consequently, the skin may suffer alterations such as photo-ageing, immune dysfunction and inflammation which may significantly affect human health. Nutraceuticals represent a promising strategy for preventing, delaying, or minimising premature ageing of the skin and also to alleviate certain skin disorders. Among them, bioactive peptides and oligosaccharides, plant polyphenols, carotenoids, vitamins and polyunsaturated fatty acids are the most widely used ingredients. Supplementation with these products has shown evidence of having an effect on the signs of ageing and protection against UV radiation ageing in several human trials. In this review, the most relevant human studies on skin nutraceuticals are evaluated and the statistical resolution, biological relevance of their results, and, the trial protocols are discussed. In conclusion, quality and rigorousness of the trials must be improved to build credible scientific evidence for skin nutraceuticals and to establish a cause-effect relationship between the ingredients the beneficial effects for the skin.
Study of the rapid thermal nitridation and silicidation of Ti using elastic recoil detection. II. Ti on SiO2 (1988)

This paper describes a study of the rapid thermal processing of Ti thin films on SiO2 in Ar and N2 in the temperature range 400–1100 °C. The resulting layer structures were analyzed by means of Rutherford backscattering spectrometry and elastic recoil detection. The latter technique yielded quantitative information with a low detection limit of the depth distribution of H, O, and N. The underlying SiO2 film starts to react with the Ti at 500 °C. Oxygen originating from the reduction of SiO2 is dissolved in the Ti layer. As long as the solubility limit of O in Ti is not reached, nitridation of the Ti in the surface region causes O to be snow-plowed out of the top surface layers. The reaction of Ti with SiO2 is characterized by an activation energy of 0.7 eV. For the case of rapid thermal processing in N2, the evolution of the layer structure is governed by a competition between nitridation and the above-mentioned oxidation of Ti. In between the Ti oxide and the remaining SiO2, a silicide of probable composition Ti5Si3 is formed.
