Optimized Paging Cache Mappings for efficient location management (2002)

Cellular IP maintains distributed cache for location management and routing purposes. Distributed paging cache coarsely maintains the position of idle mobile hosts in a service area. Cellular IP uses this paging cache to quickly and efficiently find idle mobile. It can accommodate a large number of users attached to the network without overloading the location management system. Though paging caches may be put in a few selected nodes only, those are considerably large databases. More paging caches result in less paging load in exchange for increased hardware cost. In this paper we present Optimized Paging Cache Mappings for efficient location management. It reduces the size of the paging cache and the paging-update packets. It results in saving hardware cost.

Protocols for lung protective ventilation (2005)

Protocols have a well-established role in clinical research and are increasingly being used to direct routine clinical care. In this article, we review the differing goals of research and clinical protocols and outline the similar process for their development. We use the mechanical ventilation protocol of the ARDS Network trial comparing small with traditional tidal volumes as an example. As a starting point for debate, we also suggest guiding principles and specific components of a protocol for high-frequency oscillatory ventilation.
Implications of adenylate kinase-governed equilibrium of adenylates on contents of free magnesium in plant cells and compartments (2001)

On the basis of the equilibrium of adenylate kinase (AK; EC 2.7.4.3), which interconverts MgATP and free AMP with MgADP and free ADP, an approach has been worked out to calculate concentrations of free magnesium (Mg2+), based on concentrations of total ATP, ADP and AMP in plant tissues and in individual subcellular compartments. Based on reported total adenylate contents, [Mg2+] in plant tissues and organelles varies significantly depending on light and dark regimes, plant age and developmental stage. In steady-state conditions, [Mg2+] in chloroplasts is similar in light and darkness (in the millimolar range), whereas in the cytosol it is very low in the light and increases to about 0.4mM in darkness. During the dark-to-light transition (photosynthetic induction), the [Mg2+] in chloroplasts falls to low values (0.2mM or less), corresponding to a delay in photosynthetic oxygen evolution. This delay is considered to result from lower activities of Mg-dependent enzymes in the Calvin cycle. In mitochondria, the changes in [Mg2+] are similar but smoother. On the other hand, when the transition from light to darkness is considered, an initial increase in [Mg2+] occurs in both chloroplasts and mitochondria, which may be of importance for the control of key regulatory enzymes (e.g. mitochondrial malic enzyme and pyruvate dehydrogenase complex) and for processes connected with light-enhanced dark respiration. A rationale is presented for a possible role of [MgATP]/[MgADP] ratio (rather than [ATPtotal]/[ADPtotal]) as an important component of metabolic cellular control. It is postulated that assays of total adenylates may provide an accurate measure of [Mg2+] in plant tissues/cells and subcellular compartments, given that the adenylates are equilibrated by AK.
Joint Mitigation of Laser Phase Noise and Fiber Nonlinearity Using Pilot-Aided Transmission for Single-Carrier Systems (2011)

Enabled by single-sideband-subcarrier modulation of both quadratures in the DSP-domain, we propose pilot-aided transmission in single-carrier systems to mitigate jointly laser phase noise and fiber nonlinearity. Performance improvement in linear and nonlinear regimes is demonstrated.

Automatic transmission and capture of medical data from a mumps system to a rsts system (2005)

The daily automatic transfer of medical information is being done from a MUMPS-based system to a RSTS-based system. The MUMPS system is used for medical group practice management, whereas the RSTS system is used for research purposes. Medically significant information that is collected as part of the billing function is transferred from one system to the other. This is done automatically; the procedures that accompIish the transfer are built from low cost, commercially available software. These procedures have been found to be intolerant of error and have a high failure rate.
Standardization of the Important Test Parameters in the Solder Ball Shear Test for Evaluation of the Mechanical Joint Strength (2005)

The ball shear test was investigated in terms of the etfects of test parameters, i.e., shear height and shear speed, with an experimental and non-linear finite element analysis for evaluating the solder joint integrity of area array packages. Two representative Pb-free solder compositions were examined in this work: Sn-3.5Ag-0.75Cu and In-48Sn. The substrate was a common SMD type with solder bond pad openings of 460 ㎛ in diameter. The microstructural investigations were carried out using SEM, and the IMCs were identified with EDS. Shear tests were conducted with the two varying test parameters. It could be observed that increasing shear height, at fixed shear speed, has the effect of decreasing shear force for both Sn-3.5Ag-0.75Cu and In-48Sn solder joints, while the shear force increased with increasing shear speed at fixed shear height. Too high shear height could cause some undesirable effects on the test results such as unexpected high standard deviation values or shear tip sliding from the solder ball. The low shear height conditions were favorable for screening the type of brittle interfacial fractures or the degraded layers in the interfaces. The shear speed conditions were discussed with the stress analyses of the solder ball, and we cannot find any conspicuous finding which is related to optimum shear speed from the stress analyses.
RADAR CALIBRATION (2002)

Ionic Liquids in Tribology (2009)

Current research on room-temperature ionic liquids as lubricants is described. Ionic liquids possess excellent properties such as non-volatility, non-flammability, and thermo-oxidative stability. The potential use of ionic liquids as lubricants was first proposed in 2001 and approximately 70 articles pertaining to fundamental research on ionic liquids have been published through May 2009. A large majority of the cations examined in this area are derived from 1,3-dialkylimidazolium, with a higher alkyl group on the imidazolium cation being beneficial for good lubrication, while it reduces the thermo-oxidative stability. Hydrophobic anions provide both good lubricity and significant thermo-oxidative stability. The anions decompose through a tribochemical reaction to generate metal fluoride on the rubbed surface. Additive technology to improve lubricity is also explained. An introduction to tribology as an interdisciplinary field of lubrication is also provided.
Identifying symptoms of recurrent faults in log files of distributed information systems (2010)

The manual process to identifying causes of failure in distributed information systems is difficult and time-consuming. The underlying reason is the large size and complexity of these systems, and the vast amount of monitoring data they generate. Despite its high cost, this manual process is necessary in order to avoid the detrimental consequences of system downtime. Several studies and operator practice suggest that a large fraction of the failures in these systems are caused by recurrent faults. Therefore, significant efficiency gains can be achieved by automating the identification of these faults. In this work we present methods, which draw from the areas of information retrieval as well as machine learning, to automate the task of infering symptoms pertinent to failures caused by specific faults. In particular, we present a method to infer message types from plain-text log messages, and we leverage these types to train classifiers and extract rules to identify symptoms of recurrent faults automatically.
[The use of deodorants/antiperspirants does not constitute a risk factor for breast cancer]. (2008)

Based on the observation of a high incidence of breast cancer in the upper outer quadrant adjacent to the usual area of application of deodorants and/or antiperspirants, several scientific teams have advanced the hypothesis of a possible link between antiperspirants and breast cancer. The possibility of the involvement of parabens and aluminium salts, traditional components of a number of cosmetic products, has been advanced by the same teams. In order to ascertain whether this hypothesis could or could not be confirmed, a group of clinical experts in oncology was set up to search and analyse the literature data relating to the problem raised with the aim of answering three predefined questions: 1) does it exist experimental or biological arguments supporting a potential link between the use of deodorants/antiperspirants and breast cancer? 2) Does the use of deodorants/antiperspirants have any effect on the increase in the risk of breast cancer? 3) Could a causal relationship between the use of deodorants/antiperspirants and breast cancer be accepted? The scientific data were searched systematically in the PubMed database (http://www.ncbi.nlm.nih.gov/sites/entrez) using standardised search equations. Fifty-nine studies resulting from the literature search were reviewed and nineteen articles with various methodologies were selected for in-depth analysis. In view of the fact that parabens are generally not present in deodorants/antiperspirants, the reflection group's search related purely to the question of aluminium salts. Among these nineteen articles, many are methodologically unsound, do not answer to the questions posed or deal with the question of parabens and were therefore discarded by the reflection group. The expert group's conclusion coincides with those of the French, European and American health authorities. After analysis of the available literature on the subject, no scientific evidence to support the hypothesis was identified and no validated hypothesis appears likely to open the way to interesting avenues of research.
Polarisation phase-shift keying: a coherent transmission technique with differential heterodyne detection (1988)

An original coherent transmission technique with polarisation modulation and (two-channel) differential heterodyne detection is demonstrated. In a preliminary experiment, sensitivities within 4dB of the shot noise limit have been achieved. High immunity to laser phase noise is obtained.
<title>Advances in grayshade performance of active matrix electroluminescent (AMEL) microdisplays</title> (2000)

There exist many applications in military and commercial fields where rugged, lightweight microdisplays are required for helmet mounted and viewfinder display systems. Such applications typically involve the display of high resolution symbology but increasingly also include the display of full motion video. Examples of these kinds of image sources include thermal imaging and weapon sighting. Active matrix electroluminescent (AMEL) microdisplay technology developed at Planar has uniquely satisfied the demanding environmental and power requirements of military and commercial helmet mounted display and viewfinder systems. Recent advances have extended the use of AMEL microdisplays to applications requiring the display of high grayscale content, while significantly reducing the size, cost, and power of the system electronics required to drive the display. This capability has been enabled through the development of an analog addressing architecture. This paper provides a background of the analog architecture and the advantages gained by using this approach. Specifications and interface requirements are discussed for a monochrome 640 X 512 display developed using this architecture.
Programmable CMOS/Memristor Threshold Logic (2013)

This paper proposes a hybrid CMOS/memristor implementation of a programmable threshold logic gate. In this gate, memristive devices implement ratioed diode-resistor logic, while CMOS circuitry is used for signal amplification and inversion. Due to the excellent scaling prospects and nonvolatile analog memory of memristive devices, the proposed threshold logic is in-field configurable and potentially very compact. The concept is experimentally verified by implementing a 4-input symmetric linear threshold gate with an integrated circuit CMOS flip-flop, silicon diodes, and Ag/a-Si/Pt memristive devices.
Role of Electrostatic Precipitators in Particulate Control: A Retrospective and Prospective View (1975)

Abstract The paper presents an overall view of the growth, applications, technology, problem areas, and future outlook of the electrostatic precipitation process as the major instrument for high efficiency control of fine particle emissions in heavy industry in the United States. Growth in applications and the trends toward very high collection efficiencies are shown. Broader aspects and highlights of precipitator technology are examined, together with some of the more prominent recent developments and advances in the field. The changing character of precipitator design from the rather casual function of the past to a serious enterprise involving high performance and high financial stakes is brought out. Precipitator problems and strategies for correction are covered as an important phase of the technology.
Optimizing the Memory Management of a Virtual Machine Monitor on a NUMA System (2016)

Virtualization significantly degrades computational performance on nonuniform memory access (NUMA) systems. The authors propose an optimization scheme based on a memory-access model that covers the entire access path and accommodates the chain-reacting behavior of memory subsystems. A quantitative evaluation shows significant performance improvement with negligible overhead.

An Augmented Capability Architecture to Support Lattice Security and Traceability of Access (1984)

This paper describes a protection system that supports the confinement of access as required by non-discretionary access control models such as the Bell and LaPadula lattice model. The approach is to use capability-based protection at the lowest level for implementing confined domains, in support of access control lists for expressing security policies outside the security kernel. The implementation of such a system in the context of hardware support for capabilities is discussed.
Neural Sparse Voxel Fields (2020)

Photo-realistic free-viewpoint rendering of real-world scenes using classical computer graphics techniques is challenging, because it requires the difficult step of capturing detailed appearance and geometry models. Recent studies have demonstrated promising results by learning scene representations that implicitly encode both geometry and appearance without 3D supervision. However, existing approaches in practice often show blurry renderings caused by the limited network capacity or the difficulty in finding accurate intersections of camera rays with the scene geometry. Synthesizing high-resolution imagery from these representations often requires time-consuming optical ray marching. In this work, we introduce Neural Sparse Voxel Fields (NSVF), a new neural scene representation for fast and high-quality free-viewpoint rendering. NSVF defines a set of voxel-bounded implicit fields organized in a sparse voxel octree to model local properties in each cell. We progressively learn the underlying voxel structures with a differentiable ray-marching operation from only a set of posed RGB images. With the sparse voxel octree structure, rendering novel views can be accelerated by skipping the voxels containing no relevant scene content. Our method is typically over 10 times faster than the state-of-the-art (namely, NeRF(Mildenhall et al., 2020)) at inference time while achieving higher quality results. Furthermore, by utilizing an explicit sparse voxel representation, our method can easily be applied to scene editing and scene composition. We also demonstrate several challenging tasks, including multi-scene learning, free-viewpoint rendering of a moving human, and large-scale scene rendering. Code and data are available at our website: https://github.com/facebookresearch/NSVF.
Robust localization system for an autonomous mower (2015)

This paper presents a robust vision-based localization system for an autonomous mower, which is significant for both the meadow map building and the successful area covering. Instead of setting the monocular camera toward the scene, which suffers from the disturbance of moving objects, less mark points or variation of illumination, we equip the camera toward the ground with constant illumination compensation. To achieve the localization of the mower, point features are extracted and matched between pairs of frames. Motion is incremental obtained by calculate the rotation and translation transformation of matched feature point pairs. As the angle accumulated error has greater contribution to the location error, angular acceleration sensor is adopted to compensate the angle error especially in the steep turning case. Experiments on meadow with our mowers demonstrate the robustness of our localization system.
Pyrroloquinoline Quinone Improves Growth and Reproductive Performance in Mice Fed Chemically Defined Diets (2003)

Growth, reproductive performance, and indices of collagen maturation and expression were investigated in Balb/c mice fed chemically defined, amino acid-based diets with or without the addition 6 <M pyrroloquinoline quinone (PQQ)/kg diet. The diets were fed to virgin mice for 8 weeks before breeding. At weaning, the pups from successful pregnancies were fed the same diet as their respective dams. Reproductive performance was compromised in mice fed diets devoid of PQQ, and their offspring grew at slower rates than offspring from mice fed diets supplemented with PQQ. Successful mating (confirmed vaginal plugs) was not affected by the presence or absence of PQQ; however, pup viability (number of pups at parturition/number of pups at Day 4 of lactation) was decreased in PQQ-deprived mice. Conception (percentage of females giving live births) and fertility (percentage of births) were also decreased in PQQ-deprived mice. The slower rates of growth in offspring from PQQ-deprived mice were associated with decreased steady-state mRNA levels for Type I procollagen α 1 -chains in skin and lungs from neonatal mice. Values for lysyl oxidase accumulation as protein in PQQ-deficient mice also tended to be lower than corresponding values from PQQ-supplemented or -replete mice. Skin collagen solubility was increased in PQQ-deprived mice. These results indicate that PQQ supplementation can improve reproductive performance, growth, and may modulate Indices of neonatal extracellular matrix production and maturation in mice fed chemically defined, but otherwise nutritionally complete diets.
Matchmaking and Privacy in the Digital Library: Striking the right balance (1997)

Although searching for documents is the dominant paradigm in information retrieval it is often more effective to ask another person. A library can serve as a matchmaker that introduces users with common interests to each other. Several methods of matchmaking are described and their implications for privacy are discussed. An approach to prototyping matchmaking functionality is outlined.
The hunt for the CIA: factors which demonstrate corticotrophin-inhibitory activity (1989)

In the halcyon days when life was simple, many thought that pituitary hormones were under the control of single hypothalamic factors which regulated their synthesis and release. Matters became a little more complex when the search for growth hormone (GH)-releasing hormone was punctuated by the discoveries of somatostatin, which inhibited both GH and thyrotrophin (TSH), by the co-release of TSH and prolactin by thyrotrophin-releasing hormone, and then by the substantiation of other prolactin-releasing factors such as vasoactive intestinal peptide. It has since become increasingly clear that pituitary peptides are regulated by a whole series of hypothalamic factors, both stimulatory and inhibitory, and are also subject to intrapituitary paracrine modulation. There has, however, been slow acceptance of the concept that the release of adrenocorticotrophin (ACTH) too may be finely tuned by an inhibitory factor. There is clearly a predominant role for a stimulatory factor to ACTH release, the earliest candidate for
