Toward scalable cut vertex and link detection with applications in wireless ad hoc networks (2011)

Ad hoc networks are expected to have some critical connectivity properties before partitioning. Timely partition prediction signals action for improving fault tolerance and performing some data or service replication so that the network can continue functioning after partition does occur. This article surveys existing prediction concepts and discusses their scalability, simplicity, correctness, speed, communication overhead, and applications. Existing centralized algorithms declare an edge or a node as critical if its removal will separate the network into several components. Several localized definitions of critical (or cut) nodes and links, and removable nodes, are demonstrated to be simple, useful, and scalable. A node is critical if the subgraph of p-hop neighbors of node (without the node itself) is disconnected. A link is critical if its endpoints have no common p-hop neighbors (assuming that the link between them does not exist). Definitions are extended toward local k-connectivity. The false positives mostly occur when alternative routes exist but are relatively long, and therefore may not provide satisfactory service in applications. Therefore, localized protocols provide faster and often more reliable partition warnings for possible timely replication decisions. This conceptual advance provides ingredients for establishing and restoring biconnectivity.
A strategy for the production of human monoclonal antibodies reactive with lung tumor cell lines. (1984)

Epstein-Barr virus (EBV)-immortalized cell lines were established from lymphocytes derived from peripheral blood, draining lymph nodes, bone marrow aspirates, tumors, and pericardial effusions from lung cancer patients. Ten of these lines were cloned and screened against glutaraldehyde-fixed lung tumor cells for tumor-specific antibody production using an enzyme-linked immunosorbent assay. None of the 140 clones tested secreted specific antibody, suggesting that B-lymphocytes specific for tumor antigens are rare in lung cancer patients. The EBV lines from the lung cancer patients were then hybridized with a thioguanine-resistant, ouabain-resistant human B-lymphoblastoid fusion partner KR-4, in an attempt to rescue low frequency B-cell precursors. Supernatants from more than 4500 hybridomas surviving hypoxanthine-aminopterin-thymidine:ouabain selection were screened against human lung tumor cells in an enzyme-linked immunosorbent assay. Over 360 hybrids showed significant levels of activity, although most were not tumor cell specific since they also reacted with EBV-infected cells from the lymphocyte donor. Two hybridomas showed apparent specific binding early after fusion, but this activity was lost upon continued growth although, in general, hybrids continued to secrete high levels of immunoglobulin M (up to 50 micrograms/ml), in some cases, beyond 1 year in culture. The human EBV-hybridoma system described here may be useful for rescuing low-frequency tumor-reactive B-cell precursors in lung cancer patients.
Anisotropy of Nonelastic Flow in Bone (1967)

The microdeformation characteristics of 0.010-in.-diam compact bone filaments have been measured under torsional loading conditions. The effects of prestrain, recovery, cyclic loading, and specimen orientation on the nature and extent of the nonelastic flow were determined. Correlations are considered between the mechanical behavior and the composite structure of compact bone.
Complete genome sequence of the cellulose-producing strain Komagataeibacter nataicola RZS01 (2017)

Komagataeibacter nataicola is an acetic acid bacterium (AAB) that can produce abundant bacterial cellulose and tolerate high concentrations of acetic acid. To globally understand its fermentation characteristics, we present a high-quality complete genome sequence of K. nataicola RZS01. The genome consists of a 3,485,191-bp chromosome and 6 plasmids, which encode 3,514 proteins and bear three cellulose synthase operons. Phylogenetic analysis at the genome level provides convincing evidence of the evolutionary position of K. nataicola with respect to related taxa. Genomic comparisons with other AAB revealed that RZS01 shares 36.1%~75.1% of sequence similarity with other AAB. The sequence data was also used for metabolic analysis of biotechnological substrates. Analysis of the resistance to acetic acid at the genomic level indicated a synergistic mechanism responsible for acetic acid tolerance. The genomic data provide a viable platform that can be used to understand and manipulate the phenotype of K. nataicola RZS01 to further improve bacterial cellulose production.
Online optimal control of a parallel hybrid with after-treatment constraint integration (2010)

The present paper deals with the activities and the results achieved under a cooperative research project between IFP, D2T, LMS, G2Elab and Renault focused on Hardware-in-the-Loop (HIL) applications to hybrid power-trains conception and assessment. The main goal of this study is the evaluation of hybrid propulsion concepts and the benefits of different degrees of hybridization in a flexible architecture, by using a chain of simulation platforms: from the co-simulation to the high-dynamic engine-in-the-loop test bed, through a virtual version of the last one. This paper focuses on the implementation issues of an energy management strategy (EMS) for a parallel hybrid architecture. The EMS is developed from the optimal control theory, using Pontryagin's Minimum Principle (PMP). The resulting Equivalent Consumption Minimization Strategy (ECMS) is implemented in real time and tested in an experimental environment (HyHiL test bench). In particular, a possible integration of the three way catalytic converter constraint in the optimization is presented.

Synthesis, Redox Properties, and EPR Spectroscopy of Manganese(III) Complexes of the Ligand N,N-Bis(2-hydroxybenzyl)-N′-2-hydroxybenzylidene-1,2-diaminoethane: Formation of Mononuclear, Dinuclear, and Even Higher Nuclearity Complexes (2002)

The synthesis and characterization of the title trisphenolate ligand are described. From its reaction with manganese(III) three complexes were isolated. The crystal structures revealed one pentacoordinate monomer and two similar dimers with different solvents of crystallization. In the dimers the metal ions are hexacoordinate and connected through bridging of two phenolates. A combination of electrochemistry and EPR spectroscopy showed that, in acetonitrile, the isolated batches were all identical and mainly monomeric, indicating that the mononuclear complex is in equilibrium with the dimer and perhaps also with complexes of higher nuclearity, as suggested by the detection of both the trimer and the tetramer by electrospray ionization mass spectrometry (ESI-MS). The successful use of the monomer batch as an epoxidation catalyst indicated that a high-valent manganese-oxo species can be formed, although it is probably short-lived. This is also suggested by EPR studies of the species formed by electrochemical oxidation of the complex. Upon one-electron oxidation, a manganese(IV) species was formed, which was at least partly converted to another species containing a phenoxy radical.
Selenium (Selsun) in the Treatment of Marginal Blepharitis (1956)

<h3>INTRODUCTION</h3> The widespread prevalence of blepharitis marginalis, described by Duke-Elder<sup>1</sup>as "a subacute or chronic inflammation of the margins of the lids," is well known. Its etiology is both complex and manifold and has not been conclusively defined. Classically, this condition can be divided into two broad categories: (1) simple squamous blepharitis and (2) ulcerative blepharitis. The first reflects hyperemia, congestion, and edema of the lid margins with a consequent scaling of the lids. The latter involves the ciliary follicles and associated sebaceous glands of Zeis and sweat glands of Moll. At first, suppurative abscesses develop intrafollicularly, followed by more extensive destructive inflammation and subsequent scarring. The usual complications which follow include chronic conjunctivitis, hordeolum, chalazion, ectropion, entropion, trichiasis, and keratitis. The principal causes to which blepharitis has been attributed * may be classified as those stemming from (1) predisposing factors, including eyestrain, metabolic disorder, vitamin deficiency, and heredity; (2)

High performance of potassium n-doped carbon nanotube field-effect transistors (2004)

We describe a robust technique for the fabrication of high performance vertically scaled n-doped field-effect transistors from large band gap carbon nanotubes. These devices have a tunable threshold voltage in the technologically relevant range (−1.3 V⩽Vth⩽0.5 V) and can carry up to 5–6 μA of current in the on-state. We achieve such performance by exposure to potassium (K) vapor and device annealing in high vacuum. The treatment has a twofold effect to: (i) controllably shift Vth toward negative gate biases via bulk doping of the nanotube (up to about 0.6e−/nm), and (ii) increase the on-current by 1–2 orders of magnitude. This current enhancement is achieved by lowering external device resistance due to more intimate contact between K metal and doped nanotube channel in addition to potential reduction of the Schottky barrier height at the contact.

Post-stroke balance rehabilitation under multi-level electrotherapy: a conceptual review (2014)

Stroke is caused when an artery carrying blood from heart to an area in the brain bursts or a clot obstructs the blood flow thereby preventing delivery of oxygen and nutrients. About half of the stroke survivors are left with some degree of disability. Innovative methodologies for restorative neurorehabilitation are urgently required to reduce long-term disability. The ability of the nervous system to respond to intrinsic or extrinsic stimuli by reorganizing its structure, function, and connections is called neuroplasticity. Neuroplasticity is involved in post-stroke functional disturbances, but also in rehabilitation. It has been shown that active cortical participation in a closed-loop brain machine interface (BMI) can induce neuroplasticity in cortical networks where the brain acts as a controller, e.g., during a visuomotor task. Here, the motor task can be assisted with neuromuscular electrical stimulation (NMES) where the BMI will act as a real-time decoder. However, the cortical control and induction of neuroplasticity in a closed-loop BMI is also dependent on the state of brain, e.g., visuospatial attention during visuomotor task performance. In fact, spatial neglect is a hidden disability that is a common complication of stroke and is associated with prolonged hospital stays, accidents, falls, safety problems, and chronic functional disability. This hypothesis and theory article presents a multi-level electrotherapy paradigm toward motor rehabilitation in virtual reality that postulates that while the brain acts as a controller in a closed-loop BMI to drive NMES, the state of brain can be can be altered toward improvement of visuomotor task performance with non-invasive brain stimulation (NIBS). This leads to a multi-level electrotherapy paradigm where a virtual reality-based adaptive response technology is proposed for post-stroke balance rehabilitation. In this article, we present a conceptual review of the related experimental findings.
A Thin All Epitaxial Silicon Detector with Internal Amplification (1976)

An all epitaxial silicon avalanche diode (ESAD) having a total thickness of 36 μ (4 × 10-4 radiation lengths) has been fabricated. The design lends itself to the fabrication of thin detectors having an enhanced sensitivity to minimum ionizing particles. The uniformity of gain, signal to noise, and resolution of the detectors are studied. The response of the detector to minimum ionizing particles is measured.
PIND: High spatial resolution by pinhole neutron diffraction (2018)

A pinhole neutron diffraction (PIND) technique was developed to enable improving the spatial resolution down to 250 μm. Instead of the conventional engineering diffraction method which integrates all the diffraction signals on the detector plane, the PIND setup utilizes the diffraction pattern of each pixel on 2D detectors. The proposed PIND arrangement enables improving the spatial resolution of time-of-flight instruments and allows solving problems involving steep gradients of strain or texture. The phase content and preferential orientation of grains inside samples can be spatially resolved in 2D/3D. Further, PIND retains the capability of in-situ non-destructive neutron diffraction mapping of lattice strain and grain orientation under external stimuli such as temperature and force.
Load distributing for locally distributed systems (1992)

The problem of judiciously and transparently redistributing the load of the system among its nodes so that overall performance is maximized is discussed. Several key issues in load distributing for general-purpose systems, including the motivations and design trade-offs for load-distributing algorithms, are reviewed. In addition, several load-distributing algorithms are described and their performances are compared. These algorithms are sender-initiated algorithms, receiver-initiated algorithms, symmetrically initiated algorithms, and adaptive algorithms. Load-distributing policies used in existing systems are examined, and conclusions about which algorithm might help in realizing the most benefits of load distributing are drawn.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Laboratory evaluation of a new nitrogen mustard, 2-[di-(2-chloroethyl)amino-methyl]benzimidazole, and of other 2-chloroethyl compounds. (1957)

A new nitrogen mustard derivative, 2-[di-(2-chloroethyl)aminomethyl]benzimidazole, in which the reactive alkylating moiety is attached to a putative purine antagonist, has been synthesized, and its carcinostatic activity against a variety of experimental mouse tumors has been evaluated. This compound inhibits not only the Ehrlich ascites carcinoma, which responds readily to many alkylating agents, but also mammary Adenocarcinomas 755 and E 0771 and Sarcoma 180. Comparative results obtained with a small series of previously known alkylating agents (antimalarial mustards, chlorambucil) and with a number of other mono- and bifunctional nitrogen mustard analogs, none of which inhibit the growth of these solid tumors significantly, are presented.
Ultrastructural and histochemical differences in cell surface properties of strain-specific and nonstrain-specific TA3 adenocarcinoma cells. (1977)

Transmission and scanning electron microscopy and histochemical and biochemical methods were used to investigate differences in cell structure and cell surface properties between the strain-specific TA3-St and nonstrain-specific TA3-Ha ascites sublines of the TA3 murine mammary adenocarcinoma. The TA3-St subline is lethal only to the syngeneic strain A mouse (the strain of origin), whereas the TA3-Ha subline is lethal even to foreign species. In contrast to the TA3-St cell surface, which has numerous folds and irregular microprojections, the TA3-Ha cell has abundant long microvilli of uniform dimensions. An extensive cell surface coat which resembles the "fuzz" coat found on microvilli of normal epithelium was present on the TA3-Ha, but not on the TA3-St cells. After routine fixation, the surface coat of the TA3-Ha cell usually appeared as a filamentous network extending 30-50 nm from the plasmalemma; occasionally, longer filamentous or rod-like structures were found extending 200-400 nm from the plasmalemma. The cell coat material was more extensive on the microvilli than on the intermicrovillous membranes. Free virus-like particles associated with TA3-Ha cells have a similar-appearing surface coat on their outer membranes. The density of surface anionic sites, determined with polycationic ferritin, was greater on the TA3-Ha than on the TA3-St cell surface, consistent with the presence at the TA3-Ha cell surface of several-fold more neuraminidase-susceptible sialic acid groups. The observed surface features of the nonstrain-specific TA3-Ha cell, in comparison to the strain-specific TA3-St cell, are consistent with the suggestion that sialic acid-rich glycoproteins at the TA3-Ha cell surface mask histocompatibility antigens and enhance the ability of malignant cells to invade foreign species.
Flexible Anonymization For Privacy Preserving Data Publishing: A Systematic Search Based Approach (2007)

k-anonymity is a popular measure of privacy for data publishing: It measures the risk of identity-disclosure of individuals whose personal information are released in the form of published data for statistical analysis and data mining purposes(e.g. census data). Higher values of k denote higher level of privacy (smaller risk of disclosure). Existing techniques to achieve k-anonymity use a variety of “generalization” and “suppression” of cell values for multi-attribute data. At the same time, the released data needs to be as “information-rich” as possible to maximize its utility. Information loss becomes an even greater concern as more stringent privacy constraints are imposed [4]. The resulting optimization problems have proven to be computationally intensive for data sets with large attribute-domains. In this paper, we develop a systematic enumeration based branch-and-bound technique that explores a much richer space of solutions than any previous method in literature. We further enhance the basic algorithm to incorporate heuristics that potentially accelerate the search process significantly.
IRIS (1977)

Regulatory and internal requirements are creating strong and growing pressures for more effective means of managing human resources. This calls for systems support more capable than is available through traditional MIS methods. There is a crucial need to extend the customary MIS role, beyond providing regular functions and procedures to assure timeliness and integrity of raw data, to be capable of becoming an integral part of the management process itself through ad hoc inquiry and analysis. This must be a facility which is put at the direct and personal disposal of the manager. The degree to which such an information technology genuinely assists a decision maker in pursuing a train of thought is the most relevant and, in the final analysis, perhaps the only true measure of its effectiveness.Currently available data base designs, high-level analysis and inquiry languages and interactive computing have been combined into a systems architecture which makes such decision support systems a practical reality. This paper describes one such system. It is in regular daily use ina highly diverse industrial enterprise as a transaction driven data system, but is designed for the noncomputeroriented manager in a problem-solving situation as the intended ultimate end user.
Investigations into the Mechanism by Which Sulfated Polysaccharides Inhibit HIV Infection In Vitro (1992)

Sulfated polysaccharides have been shown to inhibit human immunodeficiency virus (HIV) infection in vitro. Dextrin sulfate, fucoidan, and dextran sulfate fail to neutralize virions directly, but interact with target cells to inhibit virus entry. Ionic interactions of sulfated polyanions with oppositely charged cell surface components, including CD4, have been assumed to be the inhibitory mechanism. It is shown that the sulfated polysaccharides inhibit infection of both CD4+ and CD4- cell lines by HIV and also that they inhibit HTLV-1 and, to a lesser extent, the simian retrovirus, MPMV, which use receptors other than CD4. One binding site for radiolabeled fucoidan on the surface of human T cells is an 18 kD protein, but its significance is not yet clear.
Controlled delivery of β-globin-targeting TALENs and CRISPR/Cas9 into mammalian cells for genome editing using microinjection (2015)

Tal-effector nucleases (TALEN) and clustered regularly interspaced short palindromic repeats (CRISPR) with CRISPR-associated (Cas) proteins are genome editing tools with unprecedented potential. However, the ability to deliver optimal amounts of these nucleases into mammalian cells with minimal toxicity poses a major challenge. Common delivery approaches are transfection- and viral-based methods; each associated with significant drawbacks. An alternative method for directly delivering genome-editing reagents into single living cells with high efficiency and controlled volume is microinjection. Here, we characterize a glass microcapillary-based injection system and demonstrate controlled co-injection of TALENs or CRISPR/Cas9 together with donor template into single K562 cells for targeting the human β-globin gene. We quantified nuclease induced insertions and deletions (indels) and found that, with β-globin-targeting TALENs, similar levels of on- and off-target activity in cells could be achieved by microinjection compared with nucleofection. Furthermore, we observed 11% and 2% homology directed repair in single K562 cells co-injected with a donor template along with CRISPR/Cas9 and TALENs respectively. These results demonstrate that a high level of targeted gene modification can be achieved in human cells using glass-needle microinjection of genome editing reagents.
A New Rolling Contact Surface and “No Run-In” Performance Bearings (1995)

Plasticity indexes are usually used to describe the elastic-plastic deformation properties of a rough surface. The contact surfaces of any new rolling element bearing always change during the bearing run-in period until arriving upon a relatively stable surface texture. In this paper, a new random isotropic surface with very low plasticity index is proposed and created for the surfaces of rolling elements bearings. From both the calculated surface parameters and the run-in torque test results, the special rolling contact surfaces demonstrated “No Run-In” characteristics. Lower running torque is obtained from bearing tests and longer fatigue life is also expected by the subsurface stress analysis.
Construction of an insertional-inactivation cloning vector for Escherichia coli using a Rhodococcus gene for indigo production (1992)

pSLH8, an insertional-inactivation cloning vector for Escherichia coli has been constructed by inserting a pigment gene (probably encoding an indole dioxygenase) from Rhodococcus sp. ATCC 21145 into pUC18. Wild-type E. coli colonies containing pSLH8 produce insoluble indigo and turn dark blue on unsupplemented LB agar. Insertion of DNA fragments into the unique BamHI, EcoRI, EcoRV, HindIII, PstI, SphI and SstI polylinker cloning sites disrupts the reading frame of the fully sequenced pigment gene and results in unpigmented colonies. pSLH8 may be an attractive alternative to pUC18 and similar plasmids because it does not require specifically mutated host strains or an expensive substrate for colour development.
