A complete set of VLSI circuits for ATM switching (2002)

The broadband services offered via the ATM-based B-ISDN range from high-speed data services to imaging services. A complete chip set for ATM switching systems is presented. The VLSI components allow one to implement the most significant functions in an ATM node. Three chips are located in the exchange termination: the cell header processor that processes the ATM cells for label conversion, external to internal format translation and cell extraction and insertion, the policing unit that implements both the usage and the network parameter control functions, and the duplicated path recombining controller that duplicates and recombines respectively the input and output cell flow. The fourth component is the core of the ATM switching fabric: the broadband ATM switching element that switches the ATM cells according to the routing information written in the cell internal header, this component is presented in two different realisations (a CMOS low power 8/spl times/8, a BiCMOS 16/spl times/16). All the circuits are designed for an industrial environment and are inserted in the Italtel UTXC cross connect. System debugging testability and controllability inspired the whole chip set design. Flexibility of specifications allows one to fit other applications and future development. High performance in term of speed, low power dissipation, high integration density really stressed the technology of VLSI circuits.
Automatic mapping of uncalibrated pictures on dense 3D point clouds (2013)

This paper presents a solution for the automated texturing of models obtained from 3D scanners by using uncalibrated pictures taken with a digital camera. The proposed method exploits calibrated light intensity images given by the scanning device to automatically extract a set of correspondences with the uncalibrated pictures, such correspondences are used to give an accurate estimate for the camera pose. In a second phase the set of calibrated pictures is projected onto the model to build the texture, with a proper merging of overlapping images. The image blending is carried out by weighting the pixels of each picture depending on their depth and normal orientation. Results are proposed for sculpture datasets where a method to assess the accuracy of the mapping is applied.
Improvements in Cardiovascular Risk Profile with Large-Volume Liposuction: A Pilot Study (2001)

In this study, the authors investigated the physiologic effects of the altered body composition that results from surgical removal of large amounts of subcutaneous adipose tissue. Fourteen women with body mass indexes of greater than > 27 kg/m2 underwent measurements of fasting plasma insulin, triglycerides, cholesterol, body composition by dual-energy x-ray absorptiometry (DXA), resting energy expenditure, and blood pressure before and after undergoing large-volume ultrasound-assisted liposuction. There were no significant intraoperative complications. Body weight had decreased by 5.1 kg (p < 0.0001) by 6 weeks after liposuction, with an additional 1.3-kg weight loss (p < 0.05) observed between 6 weeks and 4 months after surgery, for a total weight loss of 6.5 kg (p < 0.00006). Body mass index decreased from (mean ± SEM) 28.8 ± 2.3 to 26.8 ± 1.5 kg/m2 (p < 0.0001). This change in body weight was primarily the result of decreases in body fat mass: as assessed by DXA, lean body mass did not change (43.8 ± 3.1 kg to 43.4 ± 3.6 kg, p = 0.80), whereas DXA total body fat mass decreased from 35.7 ± 6.3 to 30.1 ± 6.5 kg (p < 0.0001). There were significant decreases in fasting plasma insulin levels (14.9 ± 6.5 mIlU/ml before liposuction versus 7.2 ± 3.2 mIU/ml 4 months after liposuction, p < 0.007), and systolic blood pressure (132.1 ± 7.2 versus 120.5 ± 7.8 mmHg, p < 0.0002). Total cholesterol, high-density lipoprotein cholesterol, plasma triglycerides, and resting energy expenditure values were not significantly altered after liposuction. In conclusion, over a 4-month period, large-volume liposuction decreased weight, body fat mass, systolic blood pressure, and fasting insulin levels without detrimental effects on lean body mass, bone mass, resting energy expenditure, or lipid profiles. Should these improvements be maintained over time, liposuction may prove to be a valuable tool for reducing the comorbid conditions associated with obesity. (Plast. Reconstr. Surg. 108: 510, 2001.)
<title>Distributed tactical surveillance with ATVs</title> (1999)

In Carnegie Mellon University's CyberScout project, we are developing mobile robotic technologies that will extend the sphere of awareness and mobility of small military units while exploring issues of command and control, task decomposition, multi-agent collaboration, efficient perception algorithms, and sensor fusion. This paper describes our work on robotic all-terrain vehicles (ATVs), one of several platforms within CyberScout. We have retrofitted two Polaris ATVs as mobile robotic surveillance and reconnaissance platforms. We describe the computing, sensing, and actuation infrastructure of these platforms, their current capabilities, and future research and applications.

Novel on-demand droplet generation for selective fluid sample extraction (2012)

A novel microfluidic device enabling selective generation of droplets and encapsulation of targets is presented. Unlike conventional methods, the presented mechanism generates droplets with unique selectivity by utilizing a K-junction design. The K-junction is a modified version of the classic T-junction with an added leg that serves as the exit channel for waste. The dispersed phase fluid enters from one diagonal of the K and exits the other diagonal while the continuous phase travels in the straight leg of the K. The intersection forms an interface that allows the dispersed phase to be controllably injected through actuation of an elastomer membrane located above the inlet channel near the interface. We have characterized two critical components in controlling the droplet size-membrane actuation pressure and timing as well as identified the region of fluid in which the droplet will be formed. This scheme will have applications in fluid sampling processes and selective encapsulation of materials. Selective encapsulation of a single cell from the dispersed phase fluid is demonstrated as an example of functionality of this design.
Screening for depression in pregnancy: Characteristics of the Beck Depression Inventory (1996)

The Beck Depression Inventory can serve as a rapid screening test for depression during pregnancy. A higher cutoff value is required for pregnant women than is customarily used outside of pregnancy.
Linguistic Features of Noncoding DNA Sequences (1994)

We extend the Zipf approach to analyzing linguistic texts to the statistical study of DNA base pair sequences and find that the noncoding regions are more similar to natural languages than the coding regions. We also adapt the Shannon approach to quantifying the "redundancy" of a linguistic text in terms of a measurable entropy function, and demonstrate that noncoding regions in eukaryotes display a smaller entropy and larger redundancy than coding regions, supporting the possibility that noncoding regions of DNA may carry biological information.
Response of the human T-cell leukemia virus type 1 long terminal repeat to cyclic AMP (1989)

The sequences that control transcriptional initiation of the provirus of the human T-cell leukemia virus type 1 (HTLV-1) are shown to be responsive to intracellular levels of cyclic AMP. A heptanucleotide sequence present within the 21-nucleotide repeat sequence that is similar to the cyclic AMP-responsive consensus (CRE) sequence was required for cyclic AMP-mediated increase in gene expression. Although the CRE-like sequences were contained within sequences that were responsive to the virally encoded trans-activator (tax), the evidence presented indicates that the mechanisms of promoter induction by the tax product and cyclic AMP are independent. The implication of cyclic AMP stimulation of HTLV-1 provirus gene expression for long-term persistence of infected T cells and for virus-induced transformation is discussed.
The Chromic Phase Transition in Hydrogen Bonded Polydiacetylenes (1996)

Abstract Thermochromism in the polydiacetylenes(PDA) from the alkylurethanes of 5, 7-dodecadiyn-1, 12-diol is associated with a first order phase transition involving the expansion of the crystallographic unit cell, the preservation of the urethane hydrogen bonding, and possibly some relief of mechanical strain upon heating. Insights into thermochromism obtained from recent studies of nonthermochromic forms of PDA-ETCD are presented. Initial observations of the surfaces of single crystals of several PDA in this class by atomic force microscopy are consistent with known crystallographic data.
Role of Cyanobacterial Exopolysaccharides in Phototrophic Biofilms and in Complex Microbial Mats (2015)

Exopolysaccharides (EPSs) are an important class of biopolymers with great ecological importance. In natural environments, they are a common feature of microbial biofilms, where they play key protective and structural roles. As the primary colonizers of constrained environments, such as desert soils and lithic and exposed substrates, cyanobacteria are the first contributors to the synthesis of the EPSs constituting the extracellular polymeric matrix that favors the formation of microbial associations with varying levels of complexity called biofilms. Cyanobacterial colonization represents the first step for the formation of biofilms with different levels of complexity. In all of the possible systems in which cyanobacteria are involved, the synthesis of EPSs contributes a structurally-stable and hydrated microenvironment, as well as chemical/physical protection against biotic and abiotic stress factors. Notwithstanding the important roles of cyanobacterial EPSs, many aspects related to their roles and the relative elicited biotic and abiotic factors have still to be clarified. The aim of this survey is to outline the state-of-the-art of the importance of the cyanobacterial EPS excretion, both for the producing cells and for the microbial associations in which cyanobacteria are a key component.
Zygotic Genome Activation Occurs Shortly after Fertilization in Maize (2017)

The formation of a zygote via the fusion of an egg and sperm cell and its subsequent asymmetric division herald the start of the plant's life cycle. Zygotic genome activation (ZGA) is thought to occur gradually, with the initial steps of zygote and embryo development being primarily maternally controlled, and subsequent steps being governed by the zygotic genome. Here, using maize (<i>Zea mays</i>) as a model plant system, we determined the timing of zygote development and generated RNA-seq transcriptome profiles of gametes, zygotes, and apical and basal daughter cells. ZGA occurs shortly after fertilization and involves ∼10% of the genome being activated in a highly dynamic pattern. In particular, genes encoding transcriptional regulators of various families are activated shortly after fertilization. Further analyses suggested that chromatin assembly is strongly modified after fertilization, that the egg cell is primed to activate the translational machinery, and that hormones likely play a minor role in the initial steps of early embryo development in maize. Our findings provide important insights into gamete and zygote activity in plants, and our RNA-seq transcriptome profiles represent a comprehensive, unique RNA-seq data set that can be used by the research community.
Silicon drift detectors system for high-precision light kaonic atoms spectroscopy (2021)

Abstract A large area silicon drift detectors (SDDs) system and its readout electronics have been developed by the SIDDHARTA-2 Collaboration, aiming to perform high-precision light kaonic atoms x-ray spectroscopy for the investigation of the <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" overflow="scroll"> <mml:mover> <mml:mi>K</mml:mi> <mml:mo>ˉ</mml:mo> </mml:mover> <mml:mi>N</mml:mi> </mml:math> strong interaction in the low-energy QCD regime. To perform these measurements, a linear energy response and a good energy resolution are mandatory requirements for the system, to be preserved along the whole DAQ (analog and digital) chain; such task is made even harder in the experimental environment of particles colliders, where the high background due to ionizing particles and radiation is present. The energy response of the SDDs system has been characterized with the beam-originating background generated during the commissioning phase of the DAΦNE electron–positron collider (INFN-LNF) in early 2020. The data analysis has been optimized to describe the system’s response and the background. The calibration procedure demonstrates that, despite the high and variable background of the collider, the energy response of the system is linear at the level of few eV ( <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" overflow="scroll"> <mml:mo stretchy="false">(</mml:mo> <mml:mi mathvariant="normal">Δ</mml:mi> <mml:mi>E</mml:mi> <mml:mrow> <mml:mo>/</mml:mo> </mml:mrow> <mml:mi>E</mml:mi> <mml:mo stretchy="false">)</mml:mo> <mml:mo>&lt;</mml:mo> <mml:msup> <mml:mn>10</mml:mn> <mml:mrow> <mml:mo>−</mml:mo> <mml:mn>3</mml:mn> </mml:mrow> </mml:msup> </mml:math> ), with an energy resolution of <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" overflow="scroll"> <mml:mn>157.8</mml:mn> <mml:mo>±</mml:mo> <mml:msubsup> <mml:mn>0.3</mml:mn> <mml:mrow> <mml:mo>−</mml:mo> <mml:mn>0.2</mml:mn> </mml:mrow> <mml:mrow> <mml:mo>+</mml:mo> <mml:mn>0.2</mml:mn> </mml:mrow> </mml:msubsup> </mml:math> eV for the Fe K <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" overflow="scroll"> <mml:msub> <mml:mi/> <mml:mrow> <mml:mi>α</mml:mi> </mml:mrow> </mml:msub> </mml:math> line.
A grounded-output 5-switch bipolar buck-boost converter topology for switching power amplifiers (2011)

This work presents a switching converter topology which can boost and step down the supply voltage and can deliver both positive and negative voltages to a grounded load (bipolar converter topology with non-floating output). This topology, which uses five switches to perform the power conversion, is mostly intended for switching amplifiers, especially for applications which require both boosting and inverting the supply voltage (to supply bipolar voltage signals), and/or EMI-sensitive applications. Using a single-stage switching amplifier based on this 5-switch topology, it is feasible to supply a grounded load with a symmetrical bipolar voltage signal whose magnitude extends up to several times the magnitude of the supply voltage.
Carrier-mediated fructose uptake significantly contributes to carbohydrate metabolism in human skeletal muscle (1995)

To determine whether fructose can be utilized as a metabolic substrate for skeletal muscle in man, we investigated its incorporation into glycogen, its oxidation and lactate production in isolated human skeletal muscle. Rates of fructose oxidation and incorporation into glycogen increased in the presence of increasing fructose concentrations (0.1-1.0 mM). Lactate production increased 3-fold when extracellular fructose was increased from 0.1 to 0.5 mM. Cytochalasin B, a competitive inhibitor of hexose transport mediated by the GLUT1 and GLUT4 facilitative glucose transporters, completely inhibited insulin-stimulated glucose incorporation into glycogen and glucose oxidation (P < 0.01), but did not alter fructose incorporation into glycogen or fructose oxidation. Insulin (1000 mu-units/ml) increased glucose incorporation into glycogen 2.7-fold and glucose oxidation 2.3-fold, whereas no effect on fructose incorporation into glycogen or fructose oxidation was noted. A physiological concentration of glucose (5 mM) decreased the rate of 0.5 mM fructose incorporation into glycogen by 60% (P < 0.001), whereas fructose oxidation was not altered in the presence of 5 mM glucose. Irrespective of fructose concentration, the majority of fructose taken up underwent non-oxidative metabolism. Lactate production accounted for approx. 80% of the fructose metabolism in the basal state and approx. 70% in the insulin (1000 mu-units/ml)-stimulated state. In the presence of 5 mM glucose, physiological concentrations of fructose could account for approximately 10-30% of hexose (glucose + fructose) incorporation into glycogen under non-insulin-stimulated conditions. In conclusion, fructose appears to be transported into human skeletal muscle via a carrier-mediated system that does not involve GLUT4 or GLUT1. Furthermore, under physiological conditions, fructose can significantly contribute to carbohydrate metabolism in human skeletal muscle.
연결소의 음운, 형태적 기능 (2008)

Die Fugenelemente im Deutschen lassen sich gemas ihrer Funktion in zwei Gruppen einteilen: (i) die Elemente, die mit den Flexionssuffixen der Nomen identisch sind, (ii) das Fugenelement -s. Wahrend die Elemente in (i) in eine der zwei Konstituenten in einem Kompositum oder Derivatum integriert werden, stellt das -s ein echtes Fugenelement dar in dem Sinne, dass ein Kompositum oder Derivatum mit dem Fugenelement -s eine dreigliedrige Konstruktion zeigt, wobei -s in keine der beiden Konstituenten integriert wird. Diese unterschiedliche Konstruktion der beiden Gruppen lasst sich nur adaquat erklaren, wenn die Elemente in (i) als Flexionssuffixe interpretiert werden, das -s hingegen als ein Mittel, das fur die Worter mit einem schliesenden Suffix wie -ung, -keit etc. eine weitere morphologische Operation ermoglicht.
Printed Book to Audio Book Converter for Visually Impaired (2013)

Visually impaired people are dependent solely on Braille books & audio recordings provided by NGOs. Owing to many constraints in above two approaches blind people can't have book of their choice. The presented work will provide them an opportunity to have an audio-book of their choice in English or Marathi language of any printed book having English, Marathi or Braille script. Printed text from textbook having English, Marathi or Braille script will be taken as input in the form of an image which will be converted into plain editable text with the help of Optical Character Recognition (OCR). This plain text will be then fed to Text to Speech (TTS) converter which will generate the audio output file in English or Marathi language corresponding to the input text image script. Printed book to audio book converter has been successfully implemented and satisfactory results were obtained.
Direct Measurement of Powertrain Component Efficiencies for a Light-Duty Vehicle with a CVT Operating Over a Driving Cycle (2003)

In order to determine the factors that affect fuel economy quantitatively, the power flows through the major powertrain components were measured during operation over transient cycles. The fuel consumption rate and torque and speed of the engine output and axle shafts were measured to assess the power flows in a vehicle with a CVT. The measured power flows were converted to energy loss for each component to get the efficiency. Tests were done at Phase 1 and Phase 3 of the FTP and for two different CVT shift modes. The measured energy distributions were compared with those from the ADVISOR simulation and to results from the PNGV study. For both the Hot 505 and the Cold 505, and for both shift modes, the major powertrain loss occurs in the engine, including or excluding standby losses. However, the efficiency of the drivetrain/transmission is important because it influences the efficiency of the engine. The CVT allows the engine to operate near its peak efficiency line for much of the cycle. Use of the “sports shift” mode rather than the fuel economy mode decreases the efficiency of the CVT and, thereby, moves the engine operating points away from the peak efficiency line. Even though ADVISOR uses steady state, fully warmed up maps for the engine and transmission to predict behavior over a transient cycle, it predicts the average efficiencies of the engine and CVT within 2% for the Hot 505. However, it underpredicts the fuel economy by 10%, in part due to lack of a means for accounting for the fuel cut during deceleration. The results are not as good as for the Cold 505, for which the component efficiencies and fuel economy are all overpredicts. The technique used by ADVISOR to account for the starting and warm-up need refinement.
Antihyperglycaemic and Antioxidant Effect of Rutin, a Polyphenolic Flavonoid, in Streptozotocin‐Induced Diabetic Wistar Rats (2006)

Flavonoids are non-nutritive dietary components that are widely distributed in plants. The present study investigated the antihyperglycaemic and antioxidant effect of rutin, a polyphenolic flavonoid in normal and streptozotocin-induced diabetic Wistar rats. Diabetes as induced in rats by an intraperitoneal injection of streptozotocin. Rutin was orally administered to normal and diabetic rats for a period of 45 days. Fasting plasma glucose, glycosylated haemoglobin, thiobarbituric acid reactive substances and lipid hydroperoxides were significantly (P<0.05) increased, whereas insulin, C-peptide, total haemoglobin, protein levels, non-enzymic antioxidants (glutathione, vitamin C, vitamin E and ceruloplasmin) were decreased significantly (P<0.05) in diabetic rats. Oral administration of rutin to diabetic rats significantly (P<0.05) decreased fasting plasma glucose, glycosylated haemoglobin and increased insulin, C-peptide, haemoglobin and protein levels. Administration of rutin also decreased thiobarbituric acid reactive substances and lipid hydroperoxides and increased the non-enzymic antioxidants significantly (P<0.05). Treatment of normal rats with rutin did not significantly (P<0.05) alter any of the parameters studied. These results show that rutin exhibits antihyperglycaemic and antioxidant activity in streptozotocin-induced diabetic rats.

Satellite disintegration dynamics (1975)

The subject of satellite disintegration is examined in detail. Elements of the orbits of individual fragments, determined by DOD space surveillance systems, are used to accurately predict the time and place of fragmentation. Dual time independent and time dependent analyses are performed for simulated and real breakups. Methods of statistical mechanics are used to study the evolution of the fragment clouds. The fragments are treated as an ensemble of non-interacting particles. A solution of Liouville's equation is obtained which enables the spatial density to be calculated as a function of position, time and initial velocity distribution.
