Embedded approach for device inventory collection utilizing OS programmability (2011)

A major task of managing a computer network is to gather the inventory of the devices, including hardware, software, and the configuration. It is desirable to collect this information efficiently. Traditional Network Management tools require an appliance that resides on the network to collect device information. This paper introduces a distributed, embedded approach to collect network device information without an extra appliance. Utilizing device programmability with add on scripts, the network devices can communicate with each other and perform the inventory collection tasks. The collected inventory information can be sent to network management stations or hosted inventory reporting applications. This mechanism is used on Cisco devices without any device OS upgrade by using a set of scripts to collect CLI and SNMP information from the devices. Utilizing the computing power on multiple networking devices, this distributed mechanism can concurrently collect the whole network inventory efficiently. This paper gives the overview of the approach, then drills into the architecture, mechanism of the scripts, the coding standards, performance, impact to the devices, scalability, benefits, and discusses future work.
Does Variant Hepatic Artery Anatomy in a Liver Transplant Recipient Increase the Risk of Hepatic Artery Complications After Transplantation? (2004)

Variant hepatic artery anatomy in a liver transplant recipient increased the risk of hepatic artery complications after transplantation. The smaller caliber of the native common hepatic artery may contribute to the higher risk.
Rational points on certain hyperelliptic curves over finite fields (2007)

Let $K$ be a field, $a, b\in K$ and $ab\neq 0$. Let us consider the polynomials $g_{1}(x)=x^n+ax+b, g_{2}(x)=x^n+ax^2+bx$, where $n$ is a fixed positive integer. In this paper we show that for each $k\geq 2$ the hypersurface given by the equation \begin{equation*} S_{k}^{i}: u^2=\prod_{j=1}^{k}g_{i}(x_{j}),\quad i=1, 2. \end{equation*} contains a rational curve. Using the above and Woestijne's recent results \cite{Woe} we show how one can construct a rational point different from the point at infinity on the curves $C_{i}:y^2=g_{i}(x), (i=1, 2)$ defined over a finite field, in polynomial time.
Neural complex-specific expression of xylosyl N-glycan in Ciona intestinalis (2007)

We herein report N-glycosylation profiles of the individual tissues derived from the ascidian Ciona intestinalis. Multidimensional HPLC mapping revealed that the C. intestinalis expresses high-mannose-type oligosaccharides as major N-glycans, along with paucimannose-type and complex-type oligosaccharides, in a tissue-specific manner. Notably, the trimannosyl core carrying beta1,2-xylose and alpha1,3-fucose residues was identified as a principal N-glycan in the neural complex. As far as we know, this is the first description of xylosyl N-glycan expressed in deuterostome. Furthermore, we found that this xylosyl N-glycan is exclusively displayed on a membrane-associated protein so far described as a putative protein whose gene expression is specific for the neural complex. These data suggested that the xylosyl N-glycan is associated with some neural functions of C. intestinalis.
Combinative preconditioning based on Relaxed Nested Factorization and Tangential Filtering preconditioner (2009)

The problem of solving block tridiagonal linear systems arising from the discretization of PDE is considered. The nested factorization preconditioner introduced by [J. R. Appleyard and I. M. Cheshire, {\it Nested Factorization}, SPE 12264, presented at the Seventh SPE Symposium on Reservoir Simulation, San Francisco, 1983] is an effective preconditioner for certain class of problems and a similar method is implemented in Schlumerger's Eclipse oil reservoir simulator. In this paper, a relaxed version of Nested Factorization preconditioner is proposed as a replacement to ILU(0). Indeed, the proposed preconditioner is SPD and leads to a stable splitting if the input matrix is S.P.D.\,. For ILU(0), equivalent properties hold if the input matrix is a M-matrix. Moreover it has no storage cost. Effective multiplicative/additive preconditioning is achieved in combination with Tangential filtering preconditioner with the filter vector chosen as vector of $ones$. Numerical tests are carried out with both additive and multiplicative combinations. With this setup the new preconditioner is as robust as the combination of ILU(0) with tangential filtering preconditioner.
SugarTrail: Indoor navigation in retail environments without surveys and maps (2013)

A system that helps people navigate in indoor environments on a fine-grained level can enable a variety of pervasive computing applications in retail environments. Existing indoor navigation systems rely on extensive RF tagging surveys and accurate floor plans. These prerequisites are often impractical in indoor environments. In this paper, we present SugarTrail, a system for indoor navigation assistance in retail environments that minimizes the need for active tagging and does not require existing maps. By leveraging the structured movement patterns of shoppers in retail store environments, the system provides higher accuracy than existing radio finger-printing approaches. With minimal setup and active user participation, the system automatically learns user movement pathways in indoor environments from radiofrequency and magnetic signatures. These pathways are clustered and used to automatically build a navigable virtual roadmap of the environment. We present results from a campus testbed and from actual radio measurements collected in an operational supermarket to show that SugarTrail system can navigate users with a success rate of > 85% and an average accuracy of 0.7m.
Implosion of auto-magnetizing helical liners on the Z facility (2019)

In the first auto-magnetizing liner implosion experiments on the Z Facility, precompressed internal axial fields near 150 T were measured and 7.2-keV radiography indicated a high level of cylindrical uniformity of the imploding liner's inner surface. An auto-magnetizing (AutoMag) liner is made of discrete metallic helical conductors encapsulated in insulating material. The liner generates internal axial magnetic field as a 1–2 MA, 100–200 ns current prepulse flows through the helical conductors. After the prepulse, the fast-rising main current pulse causes the insulating material between the metallic helices to break down ceasing axial field production. After breakdown, the helical liner, nonuniform in both density and electrical conductivity, implodes in 100 ns. In-flight radiography data demonstrate that while the inner wall maintains cylindrical uniformity, multiple new helically oriented structures are self-generated within the outer liner material layers during the implosion; this was not predicted by simulations. Furthermore, liner stagnation was delayed compared to simulation predictions. An analytical implosion model is compared with experimental data and preshot simulations to explore how changes in the premagnetization field strength and drive current affect the liner implosion trajectory. Both the measurement of &gt;100 T internal axial field production and the demonstration of cylindrical uniformity of the imploding liner's inner wall are encouraging for promoting the use of AutoMag liners in future MagLIF experiments.
Position-Dependent Hydrophobicity of the Antimicrobial Magainin Peptide Affects the Mode of Peptide−Lipid Interactions and Selective Toxicity (2002)

Cationic antimicrobial peptides are promising candidates as novel antibiotics of clinical usefulness. Magainin 2, a representative antimicrobial peptide isolated from the skin of the African clawed frog Xenopus leavis, electrostatically recognizes anionic lipids that are abundant in bacterial membranes, forming a peptide-lipid supramolecular complex pore, whereas the peptide does not effectively bind to zwitterionic phospholipids constituting the outer leaflets of mammalian cell membranes because of the low hydrophobicity of the peptide [Matsuzaki, K. (1999) Biochim. Biophys. Acta 1462, 1-10]. In this study, two magainin analogues with enhanced hydrophobicity, MG-H1 (GIKKFLHIIWKFIKAFVGEIMNS) and MG-H2 (IIKKFLHSIWKFGKAFVGEIMNI), with identical amino acid compositions were designed and interactions with lipid bilayers and biological activities were examined in comparison with those of MG (GIGKWLHSAKKFGKAFVGEIMNS = F5W-magainin 2). The apparent hydrophobicities and hydrophobic moments of MG-H1 and MG-H2, conventionally calculated assuming that all residues are involved in helix formation, were almost the same. MG-H2 behaved like MG except for greatly enhanced activity against zwitterionic membranes and erythrocytes. In contrast, despite a very similar calculated hydrophobicity, the observed hydrophobicity of MG-H1 was larger than that of MG-H2 because of a tendency toward helix fraying near the termini. Therefore, the physicochemical parameters of only the helical portion should be considered in characterizing peptide-lipid interactions, although this point was overlooked in most studies. Moreover, MG-H1 induced aggregation and/or fusion of negatively charged membranes. Furthermore, the peptide hydrophobicity was found to affect pore formation rate, pore size, and pore stability. These observations demonstrate that the hydrophobicity of the peptide also controls the mode of action and is dependent on the position of the hydrophobic amino acids in the peptide sequence.
Focused-Beam Electron Bombardment Evaporator (1965)

A simple focused-beam electron bombardment evaporator was developed for the controlled vaporization of carbon and other refractory materials. An electrically isolated cylindrical shield deflects and focuses the electron beam, allowing a large anode to cathode distance. This avoids interference by gas conductance, resulting in a more efficient and stable bombardment process. A performance comparison is made between the described evaporator and a conventional carbon arc evaporator.
A declarative approach to business rules in contracts (1999)

We address why, and especially how, to represent business rules in e-commerce contracts. By contracts, we mean descriptions of goods and services offered or sought, including ancillary agreements detailing terms of a deal. We observe that rules are useful in contracts to represent conditional relationships, e.g., in terms & conditions, service provisions, and surrounding business processes, and we illustrate this point with several examples. We analyze requirements (desiderata) for representing such rules in contracts. The requirements include: declarative semantics so as to enable shared understanding and interoperability; prioritized conflict handling so as to enable modular updating/revision; ease of parsing; integration into WWW-world software engineering; direct executability; and computational tractability. We give a representational approach that consists of two novel aspects. First, we give a new fundamental knowledge representation formalism: a generalized version of Courteous Lugic Programs (CLP), which expressively extends declarative ordinary logic programs (OLP) to include prioritized conflict handling, thus enabling modularity in specifying and revising rule-sets. Our approach to im-
The application of illusions and psychoacoustics to small loudspeaker configurations (2007)

An overview of some auditory illusions is given, two of whichwill be considered in more detail for the application of small loudspeaker configurations. The requirements for a good sound reproduction system generally conflict with those of consumer products regarding both size and price. A possible solution lies in enhancing listener perception and reproduction of sound by exploiting a combination ofpsychoacoustics, loudspeaker configurations and digital signal processing. The first example is based on the missing fundamental concept, the second on the combination of frequency mapping and a special driver.
Resistant ovary syndrome and premature ovarian failure in young women with galactosaemia. (1986)

Three young women with galactosaemia presented with amenorrhoea and elevated plasma levels of FSH and LH. Two of these women are sisters and ovarian biopsy confirmed premature ovarian failure in one and resistant ovary syndrome in the other. The history and ovarian histology suggested that the sister with ovarian failure may have progressed through a stage of 'follicle resistance' prior to follicular atresia. All subjects had specific bioassays for LH which were grossly elevated, and higher than the levels recorded by immunoassay.
Variability in visual working memory ability limits the efficiency of perceptual decision making (2014)

The ability to make rapid and accurate decisions based on limited sensory information is a critical component of visual cognition. Available evidence suggests that simple perceptual discriminations are based on the accumulation and integration of sensory evidence over time. However, the memory system(s) mediating this accumulation are unclear. One candidate system is working memory (WM), which enables the temporary maintenance of information in a readily accessible state. Here, we show that individual variability in WM capacity is strongly correlated with the speed of evidence accumulation in speeded two-alternative forced choice tasks. This relationship generalized across different decision-making tasks, and could not be easily explained by variability in general arousal or vigilance. Moreover, we show that performing a difficult discrimination task while maintaining a concurrent memory load has a deleterious effect on the latter, suggesting that WM storage and decision making are directly linked.
Peptides of postulated inhibin activity (1986)

A 94-residue polypeptide isolated from human seminal plasma and its chemically synthesized C-terminal 28-residue segment were studied in an in vitro inhibin bioassay utilizing rat pituitary cell cultures. Both peptides have previously been claimed to have inhibin activities, and the effects on the secretion and cellular content of gonadotrophins (FSH and LH) were now assessed in the in vitro assay. No inhibition was found. After 72 h of culture, both the cellular content and the spontaneous as well as the LHRH-stimulated release of bioactive or immunoactive FSH and LH remained unaffected. Similarly, no effects were found on the storage and/or release of prolactin, growth hormone, or thyrotropin. We conclude that both the native 94-residue peptide and the synthetic replicate of its C-terminal 28-residue segment, do not influence the pituitary FSH secretion when assessed in this in vitro system.
Further evidence for the decay k+ → π+νν (2002)

The rare kaon decay K+→π+νν̄ was observed in a data set with comparable sensitivity. The observable signature for K+→π+νν̄ decay from kaons involved the π+ track and π+ decay products. The maximum pion momentum from K+→π+νν̄ decay at rest was found to be 227 MeV/c.
Total synthesis of heptacyclic Aspidosperma alkaloids. Part 1. Preliminary experiments (1987)

A series of model experiments is described, in which methods for the construction of the alkaloids of the obscurinervine group are developed. The penultimate intermediate (44) in a synthesis of the obscurinervidine analogue lacking only the aromatic methoxy groups has been prepared.
Very Low-Voltage Analog Signal Processing Based on Quasi-Floating Gate Transistors (2004)

A novel design principle for very low-voltage analog signal processing in CMOS technologies is presented. It is based on the use of quasi-floating gate (QFG) MOS transistors. Similar to multiple input floating gate (MIFG) MOS transistors, a weighted averaging of the inputs accurately controlled by capacitance ratios can be obtained, which is the basic operating principle. Nevertheless, issues often encountered in MIFG structures, such as the initial charge trapped in the floating gates or the gain-bandwidth product degradation, are not present in QFG configurations. Several CMOS circuit realizations using open- and closed-loop topologies, have been designed. They include analog switches, mixers, programmable-gain amplifiers, track and hold circuits, and digital-to-analog converters. All these circuits have been experimentally verified, confirming the usefulness of the proposed technique for very low-voltage applications.
Investigation of the Swelling Response and Loading of Ionic Microgels with Drugs and Proteins:  The Dependence on Cross-Link Density (1999)

The pH and NaCl induced swelling response and drug and protein loading of poly(methacrylic acid-co-acrylic acid) microgels (4−10 μm diameter) were measured as a function of cross-link density. The swelling ratio (Q) of the microgels increased linearly from 2 to 12 when the mole fraction of cross-linking monomer decreased from 0.25 to 0.10 (at pH's > 5.3). In the presence of 5 M NaCl (at pH's > 5.3), microgels with cross-linking feed ratios of 0.25 and 0.10 swelled to only 80% and 60% of their maximum volume measured at low ionic strength, respectively. To determine the average pore size in the different cross-linking density microgels (feed ratios = 0.25, 0.20, 0.15, and 0.10), we measured the size cutoffs for the uptake of different sized proteins. On the basis of these size exclusion experiments, we calculated the number of monomers between cross-links in each of these gels to be 6.5, 9.5, 12.5, and 16.5, respectively. These values were used in our theoretical modeling of the network swelling (modified Flory−Huggins thermodynamic model) to predict the pH−Q dependence for different degrees of cross-linking. The model predictions of the microgel pH swelling response as a function of cross-link density were in good quantitative agreement with experiments. Experimentally, the loading of smaller drug molecules did not have clear molecular weight dependence for the different cross-link density microgels. However, differences in the loading behavior of these molecules on the basis of their partition coefficients indicated that binding affinity, molecular packing, and condensation were important factors that need to be explored to optimize microgels for use in specific drug delivery applications.
Ring Tension Applied to Thiol‐Mediated Cellular Uptake (2015)

The objective of the study was to explore the potential of ring tension in cyclic disulfides for thiol-mediated cellular uptake. Fluorescent probes that cannot enter cells were equipped with cyclic disulfides of gradually increasing ring tension. As demonstrated by flow cytometry experiments, uptake into HeLa Kyoto cells increased with increasing tension. Differences in carbon-sulfur-sulfur-carbon (CSSC) dihedral angles as small as 8° caused significant changes in uptake efficiency. Uptake with high ring tension was better than with inactivated or activated linear disulfides or with thiols. Conversion of thiols on the cell surface into sulfides and disulfides decreased the uptake. Reduction of exofacial disulfides into thiols increased the uptake of transporters with disulfides and inactivated controls with thiols. These results confirm the occurrence of dynamic covalent disulfide-exchange chemistry on cell surfaces. Mechanistic and colocalization studies indicate that endocytosis does not fully account for this cellular uptake with ring tension.
Production of prone‐to‐aggregate proteins (2013)

Expression of recombinant proteins in Escherichia coli (E. coli) remains the most popular and cost-effective method for producing proteins in basic research and for pharmaceutical applications. Despite accumulating experience and methodologies developed over the years, production of recombinant proteins prone to aggregate in E. coli-based systems poses a major challenge in most research applications. The challenge of manufacturing these proteins for pharmaceutical applications is even greater. This review will discuss effective methods to reduce and even prevent the formation of aggregates in the course of recombinant protein production. We will focus on important steps along the production path, which include cloning, expression, purification, concentration, and storage.
Optimal device placement planning for wireless building automation systems (2013)

For an optimal function of wireless building automation systems, optimal placement of wireless automation devices is essential. Due to the existence of a large number of communication partner devices and varying network topologies, optimal placement of wireless devices becomes a very complex problem particularly, if it is considered in indoor environments, where radio propagation properties deviate by large from ideal conditions. In this paper, we propose approaches for graphical device zone assignment, a generic radio propagation simulator interface and a problem-specific adaptation of optimization algorithms that can obtain multiple trade-off solutions.
Field‐Induced Carrier Generation in Conjugated Polymer Semiconductors for Dynamic, Asymmetric Junctions (2007)

A functioning dynamic memory device has been created using a polypyrrole composite material that contains immobilized anions and highly mobile cations in the form of a thin film spanning two metal electrodes in an interdigitated electrode array configuration. Dynamic asymmetric electronic behavior based on the movement of charge in response to the application of a field is demonstrated.

Bone and cartilage formation by skeletal muscle derived cells (2005)

In adult individuals when most tissues have progressively lost the ability to regenerate, bone maintains the potential for a continuous self remodeling. The bone marrow has been so far the main recognized source of osteoprogenitor cells that contribute to the turnover of the skeletal scaffold. The possibility though exists that a pool of osteoprogenitor cells resides within other adult tissues and in particular, as reported previously, in other connective tissues such as fat and skeletal muscle. In an attempt to identify an alternative source of osteoprogenitor cells other than bone marrow we looked into the skeletal muscle. A plastic adhering cell population, from now on referred to as skeletal muscle derived cells (SMDCs), was obtained from biopsies of human skeletal muscle. SMDCs were clonogenic and displayed a fibroblast-like morphology. The isolated cell population had a mesenchymal origin as indicated by abundant expression of type I collagen, fibronectin, and vimentin and appeared heterogeneous. SMDCs were positive for alpha smooth actin, and to a lesser extent for desmin and alpha sarcomeric myosin, two specific markers of the myogenic phenotype. Surprisingly though SMDCs expressed early markers of an osteogenic commitment as indicated by positive staining for alkaline phosphatase, osteopontin, and osteonectin. Under the appropriate stimuli, these cells deposited in vitro a mineralized bone matrix and a proteoglycan rich matrix. In addition, SMDCs cultured in the presence of low serum and insulin differentiated towards adipocytes developing abundant lipid droplets in the cytoplasm. Furthermore SMDCs formed three-dimensional bone tissue in vivo when implanted in an immunodeficient mouse, and a mature cartilage rudiment when maintained as a pellet culture. In summary, we report the isolation and characterization of a cell population from the human skeletal muscle not only able to express in vitro specific markers of distinct mesenchymal lineages (adipogenic, chondrogenic, and osteogenic), but most importantly, able to complete the differentiation pathway leading to the formation of bone and cartilage. In this respect SMDCs resemble bone marrow stromal cells (BMSCs).
