Algorithms for drawing trees (abstract) (1993)

In several application areas of software engineering intermediate and final products of the design activity are represented by means of diagrams. Diagrams present several advantages over other representations, since they are an aid to clear thinking (a diagram is better that a thousand words). Diagrams are external representations of organization charts, data and function schemas, structure of procedure calls, pieces of code, etc. A diagram is characterized by a meaning (the "piece of reality" it draws), and a syntax, expressed by: a graphic grammar, that defines the types of symbols and connections allowed, aesthetic criteria adopted in drawing the diagram. an underlying diagram model (e.g. hierarchical, planar, connected, etc). In software engineering tools, diagram are manipulated by several functions, such as beautification, modification, refinement, merging of several diagrams, animation, etc. Each one of such functions is characterized by specific algorithms needed for the final activity of diagram drawing. E.g. when we beautify a diagram we are interested to achieve some aesthetic criteria that were previously not respected; when we refine a diagram into a more detailed one, we are interested to maintain monotonicity of shape. Producing incrementally such a library by dynamically tailoring and merging paradigmatic algorithms, results in a new and interesting research area.

Robust 3D-mapping with time-of-flight cameras (2009)

Time-of-flight cameras constitute a smart and fast technology for 3D perception but lack in measurement precision and robustness. The authors present a comprehensive approach for 3D environment mapping based on this technology. Imprecision of depth measurements are properly handled by calibration and application of several filters. Robust registration is performed by a novel extension to the Iterative Closest Point algorithm. Remaining registration errors are reduced by global relaxation after loop-closure and surface smoothing. A laboratory ground truth evaluation is provided as well as 3D mapping experiments in a larger indoor environment.
Newt Myotubes Reenter the Cell Cycle by Phosphorylation of the Retinoblastoma Protein (1997)

Withdrawal from the cell cycle is an essential aspect of vertebrate muscle differentiation and requires the retinoblastoma (Rb) protein that inhibits expression of genes needed for cell cycle entry. It was shown recently that cultured myotubes derived from the Rb-/- mouse reenter the cell cycle after serum stimulation (Schneider, J.W., W. Gu, L. Zhu, V. Mahdavi, and B. Nadal-Ginard. 1994. Science (Wash. DC). 264:1467-1471). In contrast with other vertebrates, adult urodele amphibians such as the newt can regenerate their limbs, a process involving cell cycle reentry and local reversal of differentiation. Here we show that myotubes formed in culture from newt limb cells are refractory to several growth factors, but they undergo S phase after serum stimulation and accumulate 4N nuclei. This response to serum is inhibited by contact with mononucleate cells. Despite the phenotypic parallel with Rb-/- mouse myotubes, Rb is expressed in the newt myotubes, and its phosphorylation via cyclin-dependent kinase 4/6 is required for cell cycle reentry. Thus, the postmitotic arrest of urodele myotubes, although intact in certain respects, can be undermined by a pathway that is inactive in other vertebrates. This may be important for the regenerative ability of these animals.
An automatic in-home fall detection system using Doppler radar signatures (2016)

One in three elders over the age of 65 falls each year in the United States. This paper describes a non-invasive fall detection system based on a Doppler radar sensor. The developed system has been tested in two environments: laboratory and real senior living apartments. While some laboratory resul ts appeared in our previous papers, the main novelty of this paper consists in the deployment of our fall detection system in six apartments from TigerPlace (a senior living facility in Columbia, Missouri). The fall detection results obtained in our laboratory were excellent, with the radar placed on the ceiling performing better than on the floor. The fall detection system was then evaluated using radar data collected over two weeks in six TigerPlace apartments. The fall detection system successfully detected all six natural senior falls in an apartment for the examined one week.
Intestinal microbes and chronic diseases (2009)

Gastrointestinal microbial ecology is an important part of human micro-ecology,as well as the most complicated micro-ecology.They have formed a symbiotic relationship with the host in the long evolutionary process of mankind and have played an important role on human metabolism,growth,immune response and resistance to disease and aging.The latest research shows that the intestinal microbe with composition anomaly is likely to be the major cause of chronic diseases,such as obesity,high blood pressure and diabetes mellitus.
Inhibition of Experimental Allergic Rhinitis by the n-Butanol Fraction from the Anomalous Fruits of Gleditsia sinensis (2003)

This study was conducted to clarify the effect of the n-butanol fraction from the anomalous fruits of Gleditsia sinensis LAM. (NBGS) on experimental allergic rhinitis. NBGS (100, 200, 400 mg/kg, p.o.) dose-dependently inhibited nasal symptoms (sneezing and nasal rubbing) and dye leakage induced by antigen challenge into the nasal cavity of actively sensitized rats. Significant effects were observed at doses of 200 and 400 mg/kg. NBGS (200, 400 mg/kg) also showed a clear inhibition of sneezing and an inhibitory tendency on nasal rubbing induced by histamine in normal rats. At 400 mg/kg, it significantly reduced dye leakage induced by histamine into the nasal cavity of rats. Terfenadine (10 mg/kg, p.o.), an antihistaminic drug, clearly inhibited the nasal symptoms and the amount of dye leakage induced by antigen or histamine. Furthermore, NBGS significantly reduced in vitro histamine release from rat peritoneal mast cells triggered by compound 48/80 at concentrations of 30 and 100 microg/ml. These results suggest that NBGS may be clinically effective in alleviating the nasal symptoms of allergic rhinitis, probably by inhibiting both histamine release from mast cells and nasal vascular permeability.
Properties of B and P doped Ge nanowires (2007)

An ab initio study of the formation and segregation energies of B and P doped Ge nanowires oriented along the [110] direction is performed for fully relaxed H-passivated nanowires. The authors found the preferential dopant positions and the associated formation energies. Edge positions are favorable positions for both types of dopants. In the presence of dangling bond defects P dopants will highly favor the edge positions near the dangling bond, thereby trapping the additional carrier. The results are compared with those found for doped Si nanowires.
Improvement of High-temperature Creep Resistance in Polycrystalline Al<SUB>2</SUB>O<SUB>3</SUB> by Cations Co-doping (2004)

High-temperature creep resistance in cations co-doped polycrystalline Al2O3 was examined by uniaxial compression creep test at 1250°C. The dopant oxides used in this study were 0.1 mol% of YO1.5, ZrO2, SrO, MgO and TiO2. The creep rate in Al2O3 was significantly changed by cations co-doping. For instance, Zr/Y co-doping suppressed the creep rate in Al2O3 by a factor of about 400. A high-resolution transmission electron microscopy (HREM) and nano-probe energy dispersive X-ray spectroscopy (EDS) analysis revealed that Y and Zr cations segregate along grain boundaries. The grain boundary diffusion in Al2O3 was supposed to be retarded by the segregation of Y and Zr cations. A first-principle molecular orbital calculation was made for cations co-doped Al2O3 and cation singly doped Al2O3 model cluster. The creep rate was correlated with the value of net charge in oxygen anion. The net charge of oxygen anion was one of the most important factors to determine the creep resistance in Al2O3.

Improving cloud-based continuous integration environments (2015)

We propose a novel technique for improving the efficiency of cloud-based continuous integration development environments. Our technique identifies repetitive, expensive and time-consuming setup activities that are required to run integration and system tests in the cloud, and consolidates them into preconfigured testing virtual machines such that the overall costs of test execution are minimized. We create such testing machines by reconfiguring and opportunistically snapshotting the virtual machines already registered in the cloud.
Linking CMV Serostatus to Episodes of CMV Reactivation Following Lung Transplantation by Measuring CMV-Specifi cCD8+ T-Cell Immunity (2008)

CMV-specific immunity was assessed in a longitudinal cohort of 39 lung transplant recipients (LTR) who were followed prospectively from the time of transplant using a novel assay. At the time of surveillance bronchoscopy, CMV-specific CD8(+) T-cell responses were assessed in the peripheral blood, using the QuantiFERON-CMV assay, which measures IFN-gamma-secreting T cells following stimulation with CMV peptides. In total, 297 samples were collected from 39 LTR (CMV D+/R-, n = 8; D+/R+, n = 18; D-/R+, n = 6; D-/R-, n = 7). CMV-specific T-cell immunity was not detected in any of the CMV D-/R- LTR. In CMV seropositive LTR levels of CMV immunity were lowest early posttransplant and increased thereafter. While levels of CMV-specific immunity varied between LTR, measurements at any one time point did not predict episodes of CMV reactivation. In CMV mismatched (D+/R-) LTR, primary CMV immunity was not observed during the period of antiviral prophylaxis, but typically developed during episodes of CMV reactivation. Measuring CMV-specific CD8(+) T-cell function with the QuantiFERON-CMV assay provides insights into the interrelationship between CMV immunity and CMV reactivation in individual LTR. A better understanding of these dynamics may allow the opportunity to individualize antiviral prophylaxis in the future.

The implementation of a digital sine wave oscillator using the TMS320C25: distortion reduction and applications (1990)

The implementation of a digital sine wave oscillator using the TMS320C25 digital signal processor (DSP) is described. The system is implemented with the Dalanco Spry model 25 DSP board, and a software system is designed whereby an IBM PC host computer provides control of the waveform generator functions and parameters. Waveforms are generated using the lookup-table (LUT) method. The methods of direct LUT and linear interpolation of missing samples are implemented and compared with a method that uses a trigonometric identity to reduce the harmonic distortion of the sine wave by effectively increasing the table length of the direct LUT method. The results of an experiment performed in the digital domain are presented without consideration of the problem of analog reconstruction. The oscillator can produce a sine wave without the nonuniform sampling distortion associated with fractional addressing, over the range of 7.2 Hz to 58.8 kHz, with a resolution of 7.2 Hz using 384 data words. The trigonometric identity method uses less data memory than other methods for the same distortion levels. Waveforms for the sum of two sine waves, a frequency swept sine wave, amplitude modulation (AM), and frequency modulation (FM) signals are shown as applications of the waveform generator.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Accurate deep neural network inference using computational phase-change memory (2020)

In-memory computing using resistive memory devices is a promising non-von Neumann approach for making energy-efficient deep learning inference hardware. However, due to device variability and noise, the network needs to be trained in a specific way so that transferring the digitally trained weights to the analog resistive memory devices will not result in significant loss of accuracy. Here, we introduce a methodology to train ResNet-type convolutional neural networks that results in no appreciable accuracy loss when transferring weights to phase-change memory (PCM) devices. We also propose a compensation technique that exploits the batch normalization parameters to improve the accuracy retention over time. We achieve a classification accuracy of 93.7% on CIFAR-10 and a top-1 accuracy of 71.6% on ImageNet benchmarks after mapping the trained weights to PCM. Our hardware results on CIFAR-10 with ResNet-32 demonstrate an accuracy above 93.5% retained over a one-day period, where each of the 361,722 synaptic weights is programmed on just two PCM devices organized in a differential configuration.
Leukemic thyroiditis as the initial relapsing sign in a patient with acute lymphocytic leukemia and blast expression of the neural cell adhesion molecule (1997)

We report a patient with a history of T-cell ALL in remission who presented with symptoms and laboratory values consistent with subacute thyroiditis but was found to have leukemic thyroiditis as the first clinical manifestation of leukemic relapse. Bone marrow examination at this time demonstrated recurrent ALL. After successful re-induction with chemotherapy and an allogeneic bone marrow transplant this patient developed an isolated recurrence of her ALL manifested by symptomatic thyromegaly and a new mediastinal mass that was treated with irradiation. Despite no medullary recurrence of ALL, the patient developed pleuritic chest pain and shortness of breath and succumbed to pericardial extramedullary leukemia 9 months later. This to our knowledge is the third reported case of symptomatic ALL involvement of the thyroid gland and the first to be confirmed histologically. Furthermore, this patient had blast expression of the neural cell adhesion molecule (CD56), a cell surface marker that has not been studied in ALL but has previously been identified as a risk factor for extramedullary leukemia (EML) in acute non-lymphocytic leukemia. The authors hypothesize that CD56 expression in this patient might have contributed to her predisposition to EML.
Sonic Drying (1964)

This paper deals with the application of airborne sonic energy in the drying process. Particular emphasis is placed on the development of the Hartmann-type sound generator for this application. The mechanism of the drying of solids is shown to be a complicated process influenced by many factors. How a sound field can influence these factors and increase the rate of drying is discussed. A description of a typical sonic dryer is given in conjunction with actual applications.
Secure and Efficient Initialization and Authentication Protocols for SHIELD. (2015)

With the globalization of semiconductor production, out-sourcing IC fabrication has become a trend in various aspects. This, however, introduces serious threats from the entire untrusted supply chain. To combat these threats, DARPA (Defense Advanced Research Projects Agency) proposed the SHIELD (Supply Chain Hardware Integrity for Electronics Defense) program to design a secure hardware root-of-trust, called dielet, to be inserted into the host package of legitimately produced ICs. Dielets are RF powered and communicate with the outside world through their RF antennas. They have sensors which allow them to passively (without the need for power) record malicious events which can later be read out during an authentication protocol between the dielet and server with a smartphone as intermediary. We propose the first concrete protocol design for initialization in SHIELD and an improved protocol design for authentication in SHIELD (compared to DARPA’s call for proposals for SHIELD). As the basis for authentication we propose to use AES counter mode encryption (as opposed to DARPA’s plain AES encryption). We show that this leads to several advantages: (1) resistance to a “try-and-check ” attack which in case of DARPA’s authentication protocol
Interleukin-3 and interleukin-1 alpha allow earlier bone marrow progenitors to respond to human colony-stimulating factor 1 (1988)

Abstract By using human bone marrow cells enriched for early progenitors by selective immunoadsorption and plated at low cell density (10(3) to 10(4) cells/mL/9.6 cm2) in semisolid methylcellulose culture, we have analyzed the cooperative effects of human colony-stimulating factor 1 (CSF-1), granulocyte-macrophage-CSF (GM-CSF), interleukin-1 alpha (IL-1 alpha), and gibbon as well as human recombinant IL-3 on the formation of monocytic colonies. CSF-1 alone stimulated mature monocytic colony formation by human CFU-M. However, in the presence of IL-3 and erythropoietin, CSF-1 stimulated maximal immature monocytic colony formation at low concentrations and inhibited the formation of granulomonocytic, erythrocytic, and mixed colonies. Cultures with CSF-1 and IL-3 contained more immature monocytic colonies than did cultures with CSF-1 alone. IL-1 alpha alone had little effect. However, IL-1 alpha in combination with optimal concentrations of either CSF-1, GM- CSF, or IL-3 increased the number of colonies containing immature or mature monocytic colonies.
A capacitorless double-gate DRAM cell (2002)

A capacitorless double-gate DRAM (DG-DRAM) cell is proposed in this study. Its dual gates and thin body reduce off state leakage and. disturb problems. Dopant fluctuations, which can be particularly important in high-density arrays, are avoided by using a thin, lightly doped body. The cell's large body coefficient ((dV/sub T/)/(dV/sub BD/) transforms small gains of body potential into increased drain current. MEDICI simulations for 85/spl deg/C show that a DG-DRAM cell may sustain a measurable change in drain current several hundred milliseconds after programming. These characteristics suggest that a thin body, double-gate cell is an interesting candidate for high density DRAM technologies.
A Modified Technique for Rapid Restoration of Facial Paralysis-Short Cross-Face Nerve Graft, Short Waiting Period, and Free Muscle Transplantation (2006)

Traditionally, reconstruction for chronic facial palsy was a two-stage procedure: long cross-face nerve graft (20-25cm in length) in the first stage, followed by functioning free muscle transplantation in the second stage with a one year interval. Since November 2001, we have started to use a short nerve graft (10-15cm) to cross the face in the first stage. After a 6-months waiting period, functioning free muscle transplantation was performed for the second stage of the reconstruction. This method, developed by chance, has shown encouraging results to achieve the goal of rapid restoration. Advantages of this evolution in technique include fewer scars on the donor leg and a shorter operative time in the first stage, a shorter interval (6 months) of waiting period required for nerve degeneration and regeneration, and safer, easier and faster dissection of the previous embedded cross-face grafted nerve in the second stage, making the operation safer and operative time shorter. Finally, revision of the flap if required is also safer than before. Between 2002 and 2003, a two-year period, 58 patients were operated on by using this new technique. All patients finished the operative restoration within one year. The functional results show no difference compared with the traditional method.
Vowel-separated layout: a Thai touchscreen keyboard for people with hand movement disability (2011)

This paper introduces an approach to improve Thai text entry on virtual keyboards. We propose a word completion on new keyboard layouts called vowel-separated keyboard layouts. Based on a Thai writing system, all vowels locate only four positions i.e. top, bottom, left and right of a consonant. Thus, we design our keyboard layouts by grouping vowels with the same position together and place the vowel group buttons into four positions of keyboard area. This should reduce the searching time when typing vowels. While all consonants still contain in the middle area and the consonant's arrangement is based on standard Thai layout named Kedmanee layout. We design two type of the vowel-separated layouts i.e. distance-based layout and big-button layout. We compare the performance of the proposed layout with the ordinary layout. Both proposed layouts yield better performance than the ordinary one especially the big-button layout. Most of test subjects prefer to use big-button layout because the layout look more simple and they can easily find the character they want.
Ageing alters perivascular nerve function of mouse mesenteric arteries<i>in vivo</i> (2012)

Abstract Mesenteric arteries (MAs) are studied widely in vitro but little is known of their reactivity in vivo. Transgenic animals have enabled Ca(2+) signalling to be studied in isolated MAs but the reactivity of these vessels in vivo is undefined. We tested the hypothesis that ageing alters MA reactivity to perivascular nerve stimulation (PNS) and adrenoreceptor (AR) activation during blood flow control. First- (1A), second- (2A) and third-order (3A) MAs of pentobarbital-anaesthetized Young (3-6 months) and Old (24-26 months) male and female Cx40(BAC)-GCaMP2 transgenic mice (C57BL/6 background; positive or negative for the GCaMP2 transgene) were studied with intravital microscopy. A segment of jejunum was exteriorized and an MA network was superfused with physiological salt solution (pH 7.4, 37°C). Resting tone was 10% in MAs of Young and Old mice; diameters were ∼5% (1A), 20% (2A) and 40% (3A) smaller (P 0.05) in Old mice. Throughout MA networks, vasoconstriction increased with PNS frequency (1-16 Hz) but was ∼20% less in Young vs. Old mice (P 0.05) and was inhibited by tetrodotoxin (1 μm). Capsaicin (10 μm; to inhibit sensory nerves) enhanced MA constriction to PNS (P 0.05) by ∼20% in Young but not Old mice. Phenylephrine (an α1AR agonist) potency was greater in Young mice (P 0.05) with similar efficacy (∼60% constriction) across ages and MA branches. Constrictions to UK14304 (an α2AR agonist) were less (∼20%; P 0.05) and were unaffected by ageing. Irrespective of sex or transgene expression, ageing consistently reduced the sensitivity of MAs to α1AR vasoconstriction while blunting the attenuation of sympathetic vasoconstriction by sensory nerves. These findings imply substantive alterations in splanchnic blood flow control with ageing.
