Transparent Location Fingerprinting for Wireless Services (2002)

Abstract — Detecting the user location is crucial in a wireless environment, not only for the choice of first-hop communication partners, but also for many auxiliary purposes: Quality of Service (availability of information in the right place for reduced congestion/delay, establishment of the optimal path), energy consumption, automated insertion of location-dependent info into a web query issued by a user (for example a tourist asking informations about a monument or a restaurant, a fireman approaching a disaster area). The technique we propose in our investigation tries to meet two main goals: transparency to the network and independence from the environment. A user entering an environment (for instance a wireless-networked building) shall be able to use his own portable equipment to build a personal map of the environment without the system even noticing it. Preliminary tests allow us to detect position on a map with an average uncertainty of two meters when using information gathered from three IEEE802.11 access points in an indoor environment composed of many rooms on a 625m 2 area. Performance is expected to improve when more access points will be exploited in the test area. Implementation of the same techniques on Bluetooth are also being studied.
Synthesis and Properties of Novel Polyurethane−Urea/Multiwalled Carbon Nanotube Composites (2006)

In this paper, a new method based on sol−gel process was developed to prepare polymer/carbon nanotube composites. By modifying the multiwalled carbon nanotube (MWNT) with coupling agent, MWNT was introduced into the polyurethane−urea (PU) system by chemical linkages, and a series of novel self-cross-linkable PU/MWNT composites were then prepared. The obtained PU/MWNT composites with various MWNT contents are homogeneous and transparent materials. Mechanical property measurements show that a small amount of MWNT in the samples may increase the Young's modulus and tensile strength significantly with no loss of elongation, indicating that MWNT is an excellent reinforcing agent for polyurethane. The PU/MWNT composites also show good optical limiting properties. The normalized extinction increases and the optical limiting threshold decreases with the increase of the contents of MWNT. Thus, it is possible to change the required transmittance and transmitted energies by changing the MWNT contents in composites.
Daring to talk back (2007)

Is the experience of hearing voices ordinary or extraordinary? That question was put before delegates at a conference in 2005. This article by Mark Hayward and Rufus May attempts to capture the spirit of that conference and explores the clinical implications of considering an ostensibly unusual experience as ordinary. It demonstrates approaches that focus on the relationships people have with their voices and considers how it may be helpful to support people both to listen to their voices and talk back
Recent work in real-time music understanding by computer (1991)

Music Understanding refers to the recognition or identification of structure and pattern in musical information. Three distinct music understanding projects initiated by the author are discussed. In the first, Computer Accompaniment, the goal is to follow a performer in a score. Knowledge of the position in the score as a function of time can be used to synchronize an accompaniment to the live performer and automatically adjust to tempo variations. In the second project, it is shown that statistical methods can be used to recognize the location of an improvisor in a cyclic chord progression such as the 12-bar blues. This problem is similar to Computer Accompaniment; however, much less information is conveyed by any one note because pitches are not predetermined. The third project, Beat Tracking, attempts to identify musical beats using note-onset times from a live performance. Parallel search techniques are used to consider several hypotheses simultaneously, and both timing and higher-level musical knowledge are integrated to evaluate the hypotheses.
Design of a System for Continuous Intraocular Pressure Monitoring (2005)

Measuring intraocular pressure (IOP) has proved to be an important diagnosis tool for detecting and preventing glaucoma, a disease that could lead to blindness or even eye loss. Continuous time monitoring of IOP is important for medical research. This paper evaluates the feasibility of two kinds of passive sensors to measure IOP and presents a complete measurement system for one of them.
Spread spectrum for commercial communications (1991)

The authors describe how spread spectrum operates and explain why the FCC has allocated several spectral bands for spread spectrum. They examine what is wrong with the spectrum allocations the way they are now. They show who is using and will use spread spectrum and why. In particular, they discuss the use of spread spectrum for mobile cellular communications: the personal communications network; digital stereo; alarms; sports applications; communications in the stock exchange; police radars, radios, and covert communications, and amateur radio.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
SPOTS (2004)

Fas (CD95, APO-1, TNFRSF6) is a TNF receptor superfamily member that directly triggers apoptosis and contributes to the maintenance of lymphocyte homeostasis and prevention of autoimmunity. Although FADD and caspase-8 have been identified as key intracellular mediators of Fas signaling, it is not clear how recruitment of these proteins to the Fas death domain leads to activation of caspase-8 in the receptor signaling complex. We have used high-resolution confocal microscopy and live cell imaging to study the sequelae of early events in Fas signaling. These studies have revealed a new stage of Fas signaling in which receptor ligation leads to the formation of surface receptor oligomers that we term signaling protein oligomerization transduction structures (SPOTS). Formation of SPOTS depends on the presence of an intact Fas death domain and FADD but is independent of caspase activity. Analysis of cells expressing Fas mutations from patients with the autoimmune lymphoproliferative syndrome (ALPS) reveals that formation of SPOTS can be disrupted by distinct mechanisms in ALPS.
Efficacy of Ingelvac® PRRS MLV when rehydrated with a combination of Ingelvac MycoFLEX® and Ingelvac CircoFLEX® (2010)

Materials and Methods The efficacy of the PRRS vaccine fraction was evaluated in the pig host animal efficacy model. This allowed for the evaluation of the PRRSspecific parameters in the appropriate host animal challenge model. The PRRS efficacy evaluation was performed in conventional pigs approximately 3 weeks old. Pigs were tested and determined to be seronegative for antibodies to PRRS virus by ELISA. At approximately 3 weeks of age, animals were vaccinated with a mixture containing Ingelvac MycoFLEX, Ingelvac CircoFLEX and Ingelvac PRRS MLV in a single 2 mL dose. The trivalent vaccine treatment was created by mixing equal volumes of the Ingelvac MycoFLEX and Ingelvac CircoFLEX products (each labeled as 1 mL/dose) and rehydrating Ingelvac PRRS MLV. The mixture was then administered as a 2 mL/dose vaccination. Twenty eight days after vaccination, animals were challenged with heterologous virulent PRRS virus isolate MN/01/A2. Animals were necropsied fourteen days after challenge and the lungs were removed and scored for percent lung pathology consistent with PRRS virus infection. To demonstrate efficacy of the Ingelvac PRRS MLV vaccine in combination with the other two vaccines, total percent lung pathology was compared between the vaccinated and nonvaccinated challenge control pigs following a virulent heterologous challenge with PRRS virus. Results Percent lung pathology was significantly reduced by trivalent vaccination (Table 1).
An Evaluation of Ventilator Monitoring Alarms (1986)

Thirteen commercially available ventilator monitoring alarms supplied by the distributors were evaluated. It was decided that devices with no power failure precautions or unprotected variable controls could not be recommended for general use. By these criteria only two devices could be recommended for general use as ventilator alarms and a further three as disconnect alarms; in each instance these recommendations are subject to certain reservations and suggested modifications. A ventilator alarm should be regularly serviced and checked before use and should be not used by anyone unfamiliar with the applications or limitations of that particular device.
Isolation and partial characterization of a soluble oncofetal antigen from murine and human amniotic fluids (1991)

A soluble (cell-free) oncofetal antigen (OFA) was detected in murine and human amniotic fluids by immunostaining with the murine monoclonal antibody (MAb 115) produced by syngeneic immunization with mid-gestational mouse fetal cells. OFA was purified from the amniotic fluids by ammonium sulfate precipitation at 30-70% saturation, followed by successive gel chromatography of the OFA-containing fraction on Sephacryl-S300 HR, Q- and S-Sepharoses and lentil lectin agarose. The fraction eluted from the lentil lectin column gave a single band on SDS-PAGE of the same molecular weight as the membrane-bound OFA found on both fetal and tumor tissues of humans and several rodents. Both soluble and membrane-bound OFAs share several chemical characteristics, including binding to lentil lectin and wheat-germ agglutinin, molecular weight (44 kDa) and pI (6.8). Mild periodate oxidation of OFA did not affect its binding to MAb 115 in an enzyme-linked immunosorbent assay, indicating that the reactive epitope is a peptide.
Layer-by-Layer Incorporation of Growth Factors in Decellularized Aortic Heart Valve Leaflets (2010)

Aortic heart valve disease is a growing health problem and a tissue-engineered aortic heart valve could be a promising therapy. In this paper, decellularized porcine aortic heart valve leaflets are used as scaffolds and loaded with growth factor and heparin via layer-by-layer electrostatic deposition (LbL technique) with the final purpose to stimulate and control cellular processes. Binding and subsequent release of heparin and basic fibroblast growth factor (bFGF) from aortic valve leaflets were assessed qualitatively by immunohistochemistry and quantitatively by radioactive labeling methods. It was observed that the amount of heparin and bFGF bound to aortic heart valve leaflets was directly proportional to the concentration of heparin and bFGF in the incubation medium. Release of heparin and bFGF from the decellularized heart valve leaflets at physiological conditions was sustained over 4 days while preserving the biological activity of the released growth factor.
Nearly optimal algorithms and bounds for multilayer channel routing (1995)

This paper presents algorithms for routing channels with L ≥2 layers. For the unit vertical overlap model, we describe a two-layer channel routing algorithm that uses at most d + O(√d) tracks to route two-terminal net problems and 2d + O(√d) tracks to route multiterminal nets. We also show that d + Ω(log d) tracks are required to route two-terminal net problems in the worst case even if arbitrary vertical overlap is allowed. We generalize the algorithm to unrestricted multilayer routing and use only d/(L -1) + O(√d/L + 1)&gt; tracks for two-terminal net problems (within O(√d/L + 1) tracks of optimal) and d/(L-2) +O(√d/L + 1) tracks for multiterminal net problems (within a factor of(L-1)/(L-2) times optimal). We demonstrate the generality of our routing strategy by showing that it can be used to duplicate some of the best previous upper bounds for other models (two-layer Manhattan routing and two and three-layer knock-knee routing of two-terminal, two-sided nets), and gives a new upper bound for rotuing with 45-degree diagonal wires.
Identification of environmental Vibrio vulnificus isolates with a DNA probe for the cytotoxin-hemolysin gene (1987)

We screened 44 lactose-positive Vibrio strains isolated from the marine environment for homology with a 3.2-kilobase DNA fragment encoding the Vibrio vulnificus cytotoxin-hemolysin gene. All 29 marine isolates identified as V. vulnificus on the basis of numerical taxonomy and DNA-DNA hybridization studies hybridized with the cytotoxin gene probe, as did all V. vulnificus reference strains. Homologous gene sequences were identified in no other lactose-positive marine vibrio isolates nor in 10 other Vibrio species.
Automated Mobile pH Reader on a Camera Phone (2011)

A robust classification algorithm that applies color science and image processing techniques is developed to automatically identify the pH level on a test strip. This algorithm is implemented on a camera phone that captures color images of pH test strips for healthcare or medical purpose. The pre-installed and platform independent program in the camera cell phone then processes the images captured and is able to inform visually-challenged users of the pH level of the strip. Experimental results show that this new approach is more robust and efficient in handling reflection, skewed placements, as well as different types of color reference.
Construction of a new multi-turn time-of-flight mass spectrometer (2000)

A new type of multi-turn time-of-flight mass spectrometer was constructed, consisting of four cylindrical electric sectors and 28 electric quadrupole lenses, the size of the vacuum chamber being 60 x 70 x 20 cm. It was demonstrated that the mass resolution can be increased according to the number of cycles of the ions through the ion optical system.
SilSketch (2007)

We introduce an over-sketching interface for feature-preserving surface mesh editing. The user sketches a stroke that is the suggested position of part of a silhouette of the displayed surface. The system then segments all image-space silhouettes of the projected surface, identifies among all silhouette segments the best matching part, derives vertices in the surface mesh corresponding to the silhouette part, selects a sub-region of the mesh to be modified, and feeds appropriately modified vertex positions together with the sub-mesh into a mesh deformation tool. The overall algorithm has been designed to enable interactive modification of the surface --- yielding a surface editing system that comes close to the experience of sketching 3D models on paper.
Cardiomyopathic Syrian Hamster as a Model of Congestive Heart Failure (2008)

Cardiomyopathic Syrian hamsters (Bio TO-2 dilated strain) constitute an animal model of congestive heart failure, which progressively develops an alteration of cardiac function leading to decreased arterial blood pressure and musculo-cutaneous blood flow associated with a complex process of cardiac remodeling including left ventricle dilation, wall thinning, and greater collagen density. The protocols described in this unit are designed to assess the pharmacological effects of new therapeutic strategies on cardiac and systemic hemodynamics, morphometry (body and target organs weight), cardiac remodeling (left ventricle dilation and collagen density), and survival in this model of dilated cardiomyopathy. Examples of results obtained with enalapril, an angiotensin I converting enzyme inhibitor, are provided for illustrative purposes.
Genomic instability-based transgenic models of prostate cancer (2000)

To develop animal models that represent the broad spectrum of human prostate cancer, we created transgenic mice with targeted prostate-specific expression of two genes (ECO:RI and c-fos) implicated in the induction of genomic instability. Expression of the transgenes was restricted to prostate epithelial cells by coupling them to the tissue-specific, hormonally regulated probasin promoter (PB). The effects of transgene expression were examined histologically in prostate sections at time points taken from 4 to 24 months of age. The progressive presence of regions of mild-to-severe hyperplasia, low- and high-grade prostatic intra-epithelial neoplasia, and well-differentiated adenocarcinoma was observed in both PBECO:RI lines but no significant pathology was detected in the PBfos line. Prostate tissue of PBECO:RI mice was examined for expression of p53, proliferating cell nuclear antigen (PCNA) and Ki67 at multiple time points. Although p53 does not appear to be mutated, levels of PCNA and Ki67 are elevated and correlate with the severity of the prostatic lesions. Overall, pre-neoplastic and neoplastic stages represented in the PBECO:RI model showed similarity to corresponding early stages of the human disease. This genomic instability-based model will be used to study the mechanisms involved in the early stages of prostate carcinogenesis and to investigate the nature of subsequent events necessary for the progression to advanced disease.
Frequency synchronization algorithms for OFDM systems suitable for communication over frequency selective fading channels (2002)

In this paper, the problem of carrier synchronization of OFDM systems in the presence of a substantial frequency offset is considered. New frequency estimation algorithms for the data aided (DA) mode are presented. The resulting two stage structure is able to cope with frequency offsets in the order of multiples of the spacing between subchannels. Key features of the novel scheme-which are presented in terms of estimation error variances, the required amount of training symbols and the computational load-ensure high speed synchronization with negligible decoder performance degradation at a low implementation effort.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
The Development of Preschool Children of Heroin-Addicted Mothers: A Controlled Study (1979)

Disturbances of growth and behavior in infants and toddlers of women addicted to heroin during pregnancy have been reported in uncontrolled studies. In this study, 3- to 6-year-old children of heroin-addicted mothers were compared to three other groups matched for age, race, sex, birth weight, and socioeconomic status. Heroin-exposed children weighed less and were shorter than those in the comparison groups; 14% had a head circumference below the third percentile. Heroin-exposed children were rated by parents as less well adjusted than control children and they differed significantly in perceptual measures and on subtests of the Illinois Test of Psycholinguistic Abilities and McCarthy Scales of Children's Abilities relating to the process of organization. These findings suggest that chronic intrauterine exposure to heroin may affect growth and behavior as well as perceptual and learning processes in preschool children.
Comparison between HPLC and MALDI-TOF MS Analysis of Anthocyanins in Highbush Blueberries (2000)

High-performance liquid chromatography (HPLC) has been widely used as a reliable technique to quantify anthocyanins in food samples. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) is a new technique that is having a great impact on food analysis. This study is the first to compare HPLC and MALDI-TOF MS quantifications of anthocyanins. The analyses were carried out for highbush blueberries at different stages of anthocyanin formation. In general, both techniques provided comparable quantitative anthocyanin profiles for the samples. HPLC could distinguish anthocyanin isomers, whereas MALDI-TOF MS proved to be more rapid in the accurate identification and quantification of anthocyanins with different masses. A single MALDI-TOF MS run took just 4 min. MALDI-TOF MS analysis can serve as a rapid alternative to HPLC for the analysis of anthocyanins in fruits.
Differential Temperature Sensors Fully Compatible With a 0.35-$\mu$m CMOS Process (2007)

Four differential temperature sensors, two passive and two active, designed and fabricated in a 0.35-m standard CMOS technology, are presented and characterized. Passive sensors are based on integrated thermopiles. Each one consists of eight thermocouples (16 strips) serially connected: poly1-poly2 for the first thermopile and poly1-P+diffusion for the second one. The active sensors are based on differential amplifiers, one with single-ended output and the other with differential output. Lateral parasitic bipolar transistors are used as temperature transducer devices. Both simulated and experimental characterizations are presented. The high sensitivity of active differential temperature sensors proves the feasibility of such sensors to observe the power dissipated by devices and circuits embedded in the same silicon die, with applications to the test and characterization of circuits, packaging characterization and compensation of thermal gradients, among others.
Hollow core–shell structured Si/C nanocomposites as high-performance anode materials for lithium-ion batteries (2013)

Hollow core-shell structured Si/C nanocomposites were prepared to adapt for the large volume change during a charge-discharge process. The Si nanoparticles were coated with a SiO2 layer and then a carbon layer, followed by etching the interface SiO2 layer with HF to obtain hollow core-shell structured Si/C nanocomposites. The Si nanoparticles are well encapsulated in a carbon matrix with an internal void space between the Si core and the carbon shell. The hollow core-shell structured Si/C nanocomposites demonstrate a high specific capacity and excellent cycling stability, with capacity decay as small as 0.02% per cycle. The enhanced electrochemical performance can be attributed to the fact that the internal void space can accommodate the volume expansion of Si during lithiation, thus preserving the structural integrity of electrode materials, and the carbon shell can increase the electronic conductivity of the electrode.
Total Synthesis of the Vancomycin Aglycon (1999)

Full details of a diastereoselective total synthesis of the vancomycin aglycon are described. Two key aromatic nucleophilic substitution macrocyclizations with formation of the 16-membered diaryl ethers were enlisted for sequential CD and DE ring formations, an effective macrolactamization was developed for closure of the 12-membered biaryl AB ring system, and the defined order of CD, AB, and DE ring closures permitted selective thermal atropisomerism of the newly formed ring systems or their immediate precursors. This indirect control of the atropisomer stereochemistry allowed all synthetic material to be funneled into the one of eight atropdiastereomers characterizing the natural product.
Multiple cerebral aneurysms and subarachnoid hemorrhage in a patient with Alagille syndrome. (2004)

Although intracranial hemorrhage has frequently been found responsible for mortality in adult patients with Alagille syndrome (AGS), no specific underlying cause has been identified. We describe the case of severe subarachnoid hemorrhage in a 30-year-old woman harboring five intracranial aneurysms and multiple peripheral vascular anomalies. To evaluate a possible higher incidence of intracranial aneurysms, a study of the cerebral vasculature in all AGS patients by using noninvasive imaging techniques should be considered.
