Performance Analysis and Modeling of Different Volumetric Expanders for Small-Scale Organic Rankine Cycles (2011)

In the last years one of the main research topics in energy field is represented by Organic Rankine Cycles (ORCs), due to their applicability in energy recovery from waste heat and in distributed combined heat and power (CHP) generation, particularly in small and micro scale systems. One of the key devices of the cycle is the expander: it must have a limited cost (like all the other components, in order to ensure the economic feasibility), but also a high efficiency, since the temperature of the heat source is often low and then the cycle efficiency is inherently scarce. In the first part of this paper a literature review on various positive-displacement expanders is presented, in order to outline their performances and their application field. Then, the numerical model of a volumetric reciprocating expander is implemented. This model, and another one previously developed to simulate scroll expanders, is combined with a thermodynamic model of the whole ORC system, so that a comparison between the two technologies can be carried out. The results confirm the possibility of realizing small scale energy recovery and cogeneration (CHP) systems with acceptable electrical efficiency also adopting low-cost components, directly derived from large scale industrial components.
Update on selected markers used in risk assessment for vascular disease. (2004)

CVD remains the greatest health risk in the U.S.. Assessment of laboratory data in establishing risk and treatment modalities has come to the forefront in patient primary care. Guidelines published in the ATP III document by the NCEP have incorporated lower limits of lipids and included a number of risk factors and conditions, such as the metabolic syndrome associated with insulin-resistance, as a means for earlier detection and intervention in CVD. Endothelial dysfunction and the associated inflammatory process, including soluble plasma markers, have lead to the addition of hs-CRP as an adjunct to other laboratory indicators of CVD. The precise mechanisms and interrelationships between these factors and atherosclerosis have yielded some confusing data, along with investigations of a number of associated substances and conditions. An emerging theme is the body's response to injury and stress; a lack of metabolic balance. While currently outside the domain of routine laboratory testing, future CVD risk assessment may include the metabolic by-products generated by chronic external pressures, including genetic predisposition or alterations associated with socioeconomic factors. Further studies are needed to better understand the significance each plays in assessing the individual's development and CVD risk.
High modulation amplitude modification for Varian ESR spectrometers (1974)

A water cooling accessory was constructed to enable the use of high amplitudes on field modulation electron spin resonance spectrometers. Field modulations greater than 50 G (100 G peak-to-peak) can be used for long periods without damage to the coils by heating.
Partial surface and volume matching in three dimensions (1997)

In this paper we present a new technique for partial surface and volume matching of images in three dimensions. In this problem we are given two objects in 3-space, each represented as a set of points, and the goal is to find a rigid motion of one object which makes a sufficiently large portion of its boundary lying sufficiently close to a corresponding portion of the boundary of the second object. This is an important problem in pattern recognition and in computer vision, with many industrial, medical, and chemical applications. Our method treats separately the rotation and the translation components of the Euclidean motion that we seek. The algorithm steps through a sequence of rotations, in a steepest-descent style, and uses a novel technique for scoring the match for any fixed rotation. Experimental results on various examples, involving data from industrial applications, medical imaging, and molecular biology, are presented, and show the accurate and robust performance of our algorithm.
Investigating selection and reading performance on a mobile phone while walking (2010)

More and more people interact with their mobile phone while walking. The presented research analyzes; firstly, the negative effect of walking when considering reading and target selection tasks, such as weaker performance and higher workload. Here, we focused on one-handed interaction with a touch screen whereby the thumb is used as the input device. Secondly, we analyze how these negative effects can be compensated by increasing the text size and the size of the targets to select on the mobile phone. A comparative user study was conducted with 16 participants who performed target acquisition and reading tasks while standing and walking. The results show that whilst performance decreases, cognitive load increases significantly when reading and selecting targets when walking. Furthermore, the results show that the negative effect regarding target selection can be compensated by increasing the target size, but the text reading task did not yield better performance results for a larger text size due to the increased demand for scrolling. These results can be used to inform future designs of mobile user interfaces which might provide a dedicated walking mode.

Implementing a Forms of Consent Smart Contract on an IoT-based Blockchain to promote user trust (2018)

The H2020 European research project Safe-Guarding Home IoT Environments with Personalised Real-time Risk Control (GHOST) aims to develop a cyber-security layer on IoT smart home installations. The proposed system analyses packet-level data flows for building patterns of communications between IoT devices and external entities. To ensure non-repudiation, integrity and authentication of the data captured, they are stored in a Blockchain, a distributed ledger network, as digitally-signed transactions. Since the data can potentially include sensitive user information, it is imperative to promote trust by informing users about the operating principles of the network as well as to request the acceptance of a consent form by them. This paper presents the design and implementation of a Forms of Consent application, a Distributed Application that interacts with a set of Smart Contracts deployed on a private Ethereum network. The application is being developed as part of the GHOST project.
LLL lattice reduction-based detection of joint VBLAST and SFBC in MIMO/OFDM systems (2005)

We propose a VBLAST and space-frequency block codes (SFBC) joint transmit scheme to exploit both multiplexing and diversity gain in MIMO/OFDM systems. LLL (Lenstra-Lenstra-Lova/spl acute/sz) lattice reduction (Lenstra, A.K. et al., 1982) is applied before the signal detection to improve the bit error rate (BER) performance. Computer simulation results show that the proposed scheme significantly exploits diversity gain while a high data rate is obtained. At the same time, the simulation results confirm that the BER performance is improved obviously when LLL lattice reduction is applied to the channel matrix.
Weakly-Supervised Dual Clustering for Image Semantic Segmentation (2013)

In this paper, we propose a novel Weakly-Supervised Dual Clustering (WSDC) approach for image semantic segmentation with image-level labels, i.e., collaboratively performing image segmentation and tag alignment with those regions. The proposed approach is motivated from the observation that super pixels belonging to an object class usually exist across multiple images and hence can be gathered via the idea of clustering. In WSDC, spectral clustering is adopted to cluster the super pixels obtained from a set of over-segmented images. At the same time, a linear transformation between features and labels as a kind of discriminative clustering is learned to select the discriminative features among different classes. The both clustering outputs should be consistent as much as possible. Besides, weakly-supervised constraints from image-level labels are imposed to restrict the labeling of super pixels. Finally, the non-convex and non-smooth objective function are efficiently optimized using an iterative CCCP procedure. Extensive experiments conducted on MSRC and Label Me datasets demonstrate the encouraging performance of our method in comparison with some state-of-the-arts.
Software asset analyzer: A system for detecting configuration anomalies (2016)

In this paper, we introduce Software Asset Analyzer (SAA), a system that monitors and detects potentially vulnerable software asset modifications in end devices, and can be used to guide patch management. Software patching is a complex and failure-prone process that, on enterprise networks, requires triage. Accurate inventories of software (applications and operating systems) improve patching efficiency, which is a significant concern for security analysts. By generating asset baselines, the SAA identifies and reports abnormal deviations in individual end-devices, which allows security analysts to identify vulnerable devices and further enforce security patching. This system is also suited for detecting vulnerable software installs and remediation process verification. SAA is a low-cost and efficient method that yields accurate and complete inventories of assets on end-devices, reducing the potential loss from new vulnerabilities.

We report on the thermoelectric properties of the Heusler-type ${\mathrm{Fe}}_{2}{\mathrm{VAl}}_{1\ensuremath{-}x}{\mathrm{Ge}}_{x}$ alloys with compositions $0\ensuremath{\le}x\ensuremath{\le}0.20$. While ${\mathrm{Fe}}_{2}\mathrm{VAl}\phantom{\rule{0.3em}{0ex}}(x=0)$ exhibits a semiconductorlike behavior in electrical resistivity, a slight substitution of Ge for Al causes a significant decrease in the low-temperature resistivity and a large enhancement in the Seebeck coefficient, reaching $\ensuremath{-}130\phantom{\rule{0.3em}{0ex}}\mathrm{\ensuremath{\mu}}\mathrm{V}∕\mathrm{K}$ for $x=0.05$ at around room temperature. Comparison with the ${\mathrm{Fe}}_{2}{\mathrm{VAl}}_{1\ensuremath{-}x}{\mathrm{Si}}_{x}$ system demonstrates that the compositional variation of the Seebeck coefficient falls on a universal curve irrespective of the doping elements (Ge and Si), both of which are isoelectronic elements. The net effect of doping is most likely to cause a rigid-bandlike shift of the Fermi level from the central region in the pseudogap. In spite of a similar decrease in the electrical resistivity with composition of Ge and Si, the thermal conductivity decreases more rapidly for the Ge substitution. It is concluded that doping of heavier atoms such as Ge reduces more effectively the lattice thermal conductivity while retaining the low electrical resistivity as well as the large Seebeck coefficient.
Micro Multi-Probes Electrode Array for the Recording Retinal Neuron Signal (2007)

This research is to design micro multi-probe electrode array (MEA) for retinal neuron signal recording system, which would be used for the measurement system on bio-medical applications. Based on the optimal geometry of MEA designed by ANSYS, the novel fabrication process of MEA was accomplished by using MEMS technology based on silicon-on-insulator (SOI) wafer, inherently has good controllable probe thickness. The multi-probes with a 16-sites recording electrode array has been manufactured, which has been past for strength test by force gauge and electrical performance test by using impedance measurement system. Neuron extracellular recording by using fabricated MEA has been shown, which was comparable with the one measured by traditional glass pipettes. MEA for recording retinal neuron signal would be performed for further development.
Incretin hormones - an update (2001)

Incretin hormones are insulinotropic hormones from the intestinal mucosa, which after being released in response to ingestion of a meal, enhance insulin secretion in excess of that elicited by the absorbed nutrients (glucose. amino acids etc) themselves. To day it is well established that the most important incretin hormones are glucose-dependent insulinotropic polypeptide (GIP, previously known as gastric inhibitory polypeptide) and glucagon-like peptide-1 (GLP-1) from the upper and lower small intestinal mucosa, respectively. It has been shown that interference with the incretin function causes glucose intolerance and it has also been shown that the incretin function is greatly impaired in type 2 diabetes mellitus. The reason for this seems to be twofold: an impaired secretion of GLP-1 and a severely impaired insulinotropic effect of GIP in these patients. In agreement with this, administration of the active incretin, GLP-1, to patients with type 2 diabetes may nearly normalise their fasting and postprandial hyperglycaemia. In addition to its insulinotropic effects, GLP-1 has been shown to stimulate the formation of new beta cells in rodents, partly by enhanced beta cell proliferation and partly by enhancing differentiation of duct progenitor cells to mature beta cells. GLP-1 also inhibits glucagon secretion, inhibits gastric emptying and reduces appetite and food intake. During the last years, therefore, several most promising attempts have been made to develop GLP-1 into a clinically useful therapeutic agent for the treatment of type 2 diabetes.

Dihydroxybenzolyserine—a siderophore for E. coli (1990)

Dihydroxybenzoylserine, the breakdown product of enterochelin, was able to stimulate growth of Escherichia coli under iron limiting conditions by acting as a siderophore. The dihydroxybenzoylserine-iron complex was taken up via the outer membrane receptor proteins Fiu, FepA and to a minor extent via Cir. Transport of Fe3(+)-dihydroxybenzoylserine across the cytoplasmic membrane was only dependent on genes from the fep region. In addition, it was shown that dihydroxybenzoate was taken up via Fiu and Cir and less efficiently by FepA.
Three-dimensional Garment Dressing Simulation (2009)

The garment dressing simulation is a process which transforms multiple two-dimensional garment patterns into a three-dimensional configuration that follows the surface of the human body and enables visualization of the draping effect of the garment. The dimensional stability of a garment pattern is an important constraint that needs to be imposed to ensure the created garment has a size complying with the original design of the pattern. In this paper, we used a mass-spring system to simulate the physical properties of the fabric and adaptive sewing forces to wrap the pattern around the human model to form a virtual garment. Combined with the collision detection and response routine, the strain control for maintaining the pattern size was implemented with velocity adjustments.
Isolation, characterization, and propagation of rat conjunctival goblet cells in vitro. (2001)

Tripartite sequences within and 3' to the sea urchin H2A histone gene display properties associated with a transcriptional termination process. (1986)

We have defined a DNA sequence that behaves as an RNA polymerase II termination signal by using the human HeLa cell transient expression system. Surprisingly, this sequence is tripartite, including part of the coding region of the sea urchin H2A histone gene together with two separate sequences in the 3' flanking region of the gene. We demonstrate that this signal functions both in its normal gene environment and also when placed within the human alpha-globin gene. However, we have failed to detect a discrete 3' terminus. Rather, our data indicate the presence of an extremely heterogeneous series of nonpolyadenylated RNAs. These heterogeneous nonpolyadenylated RNAs are stable when transcribed from the intact histone gene but are highly unstable within the human alpha-globin gene. This provides evidence for the role of poly(A) in the stability of mRNA.
Three Dimensional Image Correlation of CT, MR, and PET Studies in Radiotherapy Treatment Planning of Brain Tumors (1987)

A treatment planning system for stereotactic convergent beam irradiation of deeply localized brain tumors is reported. The treatment technique consists of several moving field irradiations in noncoplanar planes at a linear accelerator facility. Using collimated narrow beams, a high concentration of dose within small volumes with a dose gradient of 10-15%/mm was obtained. The dose calculation was based on geometrical information of multiplanar CT or magnetic resonance (MR) imaging data. The patient's head was fixed in a stereotactic localization system, which is usable at CT, MR, and positron emission tomography (PET) installations. Special computer programs for correction of the geometrical MR distortions allowed a precise correlation of the different imaging modalities. The therapist can use combinations of CT, MR, and PET data for defining target volume. For instance, the superior soft tissue contrast of MR coupled with the metabolic features of PET may be a useful addition in the radiation treatment planning process. Furthermore, other features such as calculated dose distribution to critical structures can also be transferred from one set of imaging data to another and can be displayed as three-dimensional shaded structures.
Temporal Control of Gelation and Polymerization Fronts Driven by an Autocatalytic Enzyme Reaction (2016)

Abstract Chemical systems that remain kinetically dormant until activated have numerous applications in materials science. Herein we present a method for the control of gelation that exploits an inbuilt switch: the increase in pH after an induction period in the urease‐catalyzed hydrolysis of urea was used to trigger the base‐catalyzed Michael addition of a water‐soluble trithiol to a polyethylene glycol diacrylate. The time to gelation (minutes to hours) was either preset through the initial concentrations or the reaction was initiated locally by a base, thus resulting in polymerization fronts that converted the mixture from a liquid into a gel (ca. 0.1 mm min −1 ). The rate of hydrolytic degradation of the hydrogel depended on the initial concentrations, thus resulting in a gel lifetime of hours to months. In this way, temporal programming of gelation was possible under mild conditions by using the output of an autocatalytic enzyme reaction to drive both the polymerization and subsequent degradation of a hydrogel.
Cloning of cDNAs Encoding the Variable Domains of Antibody KC4G3 and Construction of a Chimeric Antibody (1993)

BrE-3 is an IgG1,kappa murine monoclonal antibody that binds to human breast epithelial mucin and that has been shown to be promising for imaging and treatment of breast cancer. We have cloned and sequenced cDNAs encoding the variable regions of the light (VL) and heavy (VH) chains of BrE-3. VL belongs to group II and resulted from a V kappa-J kappa 1 fusion. VH belongs to group IIIc and arose from a V-D-JH3 non-conservative fusion which left little or nothing of the original D minigene. Thus, the third VH CDR contains only 4 amino-acids. We constructed an IgG1,kappa human/mouse chimeric antibody (by joining the murine variable domains to human constant domains) and expressed it in SP2/0 myeloma cells. This chimeric monoclonal antibody stains breast carcinoma tissue sections by the ABC immunoperoxidase method. Its affinity for the BrE-3 antigen is 2.68 x 10(8) M-1, which, considering the experimental error, is indistinguishable from the affinity of the original murine antibody (3.75 x 10(8) M-1). The VL and VH domains alone are respectively 73%, and 63% identical to the human V kappa II and VHIII consensus sequences. If the CDRs are excluded, these numbers become respectively 82% and 80%. Therefore, we expect the reported chimeric BrE-3 to be considerably less immunogenic to humans than the original murine antibody, while retaining the original binding properties.
