The use of blocking software or Internet filters in southern New Jersey public libraries (2004)

The purpose of this study was to determine if public libraries in southern New Jersey have installed blocking software or filters on their Internet computers and, specifically, to find out what types of filters or blocking software they were currently using in their libraries. The study wanted to see how satisfied librarians were with their filters or blocking software. The study also looked at whether or not public libraries in southern New Jersey have written Acceptable Use Policies which define access to the Internet for some or all of their patrons, including children under the age of eighteen. Finally, the study examined whether or not public librarians were aware of Federal regulations including the Children's Internet Protection Act. This applied research design employed mailed questionnaires to collect data from 67 public libraries in southern New Jersey. Analysis of the data revealed that many smaller public libraries have not installed filters or blocking software on their Internet computers. Approximately half the libraries surveyed were utilizing filters or blocking software on their Internet computers for either adults or children under the age of eighteen.
Electron diffraction studies of light-induced conformational changes in the Leu-93 → Ala bacteriorhodopsin mutant (1997)

We previously have presented evidence for prominent structural changes in helices F and G of bacteriorhodopsin during the photocycle. These changes were determined by carrying out electron diffraction analysis of illuminated two-dimensional crystals of wild-type bacteriorhodopsin or the Asp-96 --> Gly mutant that were trapped at a stage in the photocycle after light-driven proton release, but preceding proton uptake from the aqueous medium. Here, we report structural analysis of the long-lived O intermediate observed in the photocycle of the Leu-93 --> Ala mutant, which accumulates after the release and uptake of protons, but before the reisomerization of retinal to its initial all-trans state. Projection Fourier difference maps show that upon illumination of the Leu-93 --> Ala mutant, significant structural changes occur in the vicinity of helices C, B, and G, and to a lesser extent near helix F. Our results suggest that (i) all four helices that line the proton channel (B, C, F, and G) participate in structural changes during the late stages of the photocycle, and (ii) completion of the photocycle involves significant conformational changes in addition to those that are associated with steps in proton transport.
Modeling Return Periods of Tropical Cyclone Intensities in the Vicinity of Hawaii* (1998)

Tropical cyclones in the vicinity of Hawaii have resulted in great property damage. An estimate of the return periods of tropical cyclone intensities is of particular interest to governments, public interest groups, and private sectors.
Chemically Programmed Cell Adhesion with Membrane-Anchored Oligonucleotides (2011)

Cell adhesion organizes the structures of tissues and mediates their mechanical, chemical, and electrical integration with their surroundings. Here, we describe a strategy for chemically controlling cell adhesion using membrane-anchored single-stranded DNA oligonucleotides. The reagents are pure chemical species prepared from phosphoramidites synthesized in a single chemical step from commercially available starting materials. The approach enables rapid, efficient, and tunable cell adhesion, independent of proteins or glycans, by facilitating interactions with complementary labeled surfaces or other cells. We demonstrate the utility of this approach by imaging drug-induced changes in the membrane dynamics of non-adherent human cells that are chemically immobilized on a passivated glass surface.
Brewster angle spectroscopy: A new method for characterization of defect levels in semiconductors (1991)

A new optical method which allows the identification of electronic defects in semiconductors is presented. Deep level characterization is done by detecting changes of the Brewster angle induced by optically excited transitions involving defects. An empirical model is developed which correlates the minima of the derivative of the Brewster angle as a function of photon energy with the energetic locations of defects in the semiconductor gap. Contactless room-temperature measurements on n-GaAs (100) and p-InP (111) clearly reveal defects with high accuracy, including the well known EL2 and EL12 centers in GaAs. The applicability of the method for semiconductor device technology processes is discussed.

GenePrint: Generic and accurate physical-layer identification for UHF RFID tags (2013)

Physical-layer identification utilizes unique features of wireless devices as their fingerprints, providing authenticity and security guarantee. Prior physical-layer identification techniques on RFID tags require non-generic equipments and are not fully compatible with existing standards. In this paper, we propose a novel physical-layer identification system, GenePrint, for UHF passive tags. The GenePrint prototype system is implemented by a commercial reader, a USRP-based monitor, and off-the-shelf UHF passive tags. Our solution is generic and completely compatible with the existing standard, EPCglobal C1G2 specification. GenePrint leverages the internal similarity among the pulses of tags' RN16 preamble signals to extract a hardware feature as the fingerprint. We conduct extensive experiments on over 10,000 RN16 preamble signals from 150 off-the-shelf RFID tags. The results show that GenePrint achieves a high identification accuracy of 99.68%+. The feature extraction of GenePrint is resilient to various malicious attacks, such as the feature replay attack.
Development of a fabric winding system for the automated manufacture of prefabricated wind turbine blade roots (2011)

In the rapidly expanding wind energy market, manufacturing processes of composite components must be continually improved to keep up with high demand and increasing part size. This research focuses on improving the offline production of the root section of wind turbine blades. In this research, a system is developed and tested to replace the two-part manual layup of the prefabricated root with an automated fabric winding machine. The system is designed to wind a limited number of long, stitched plies semi-helically around a male mold at a lower cost and higher quality than current processes. A prototype machine is created that pulls two types of Non-Crimp Fabric from supply rolls onto a rotating mandrel that matches the interior surface of a scaled down blade root. The prototype system proves Non-Crimp Fabric plies can be wound and a male mold can be used as a suitable replacement for a female mold by creating several successful prototype root sections. Process times and labor costs between the current manual layup and the winding method are also compared and show a significant reduction in glass layup, further proving the feasibility of the new system.
High Performance Fibers from Carbon Nanotubes: Synthesis, Characterization, and Applications in Composites—A Review (2017)

A carbon nanotube fiber is formed by interlocking carbon nanotubes that are perfectly aligned to give a continuous long fiber. The production of neat carbon nanotube fibers has paved the way for realization of superior mechanical and physical properties of individual carbon nanotubes at macroscopic scale. In this review paper, we elucidate the state of the art advances in fabrication methods, characterization, modeling of mechanical properties, and applications of carbon nanotube fibers as next generation high performance fibers for composites. Recommendations have been made on the aspects of design and scale-up for large scale manufacturing of carbon nanotube fibers using (a) a stepwise protocol for the determination rate controlling step(s) and the estimation of overall rate of reaction, and (b) computational fluid dynamics. Finally, the challenges and opportunities in carbon nanotube fiber research have been clearly brought out, and suggestions have been made for future work.
Real-time <i>in situ</i> x-ray diffraction as a method to control epitaxial growth (2003)

We developed a real-time in situ x-ray Bragg diffraction technique for monitoring epitaxial growth. In our setup, the x-ray diffraction requirement of an extremely exact sample adjustment and an angular scan of sample and detector are circumvented by using a slightly divergent x-ray beam and observing an extremely asymmetric Bragg reflection with a multichannel detector. The angular range covered by the stationary multichannel detector corresponds nearly exactly to the qz interval of a conventional ω−2θ scan. The technique is demonstrated by monitoring the molecular-beam epitaxial growth of a ZnSe epilayer on (001)GaAs. The exposure time of each diffraction pattern is only a few seconds, which enables a real-time x-ray diffraction monitoring of the epitaxial growth process.
Deleuze and Derrida on the Concept and Future of Democracy (2007)

This paper argues that Deleuze and Derrida share a conception of the open-ended character of political concepts that resembles in some respects the constructivist approach of Rawls and other liberal theorists. It explores the hypothesis that their understanding of concepts is related to their essentially critical conception of the task of political philosophy. It discusses Deleuze's ‘becoming-democratic’ and Derrida's ‘democracy to come’ in order to show how both philosophers offer ‘transformative’ concepts that draw in different ways upon elements of existing conceptions of democracy in order to open up new approaches to democratic politics. It points to strengths and weaknesses of both approaches before suggesting, finally, that Derrida's use of his concept of ‘democracy to come’ is in some ways the more adventurous.
Screening and detection of pancreatic cancer. Highlights from the "2011 ASCO Annual Meeting". Chicago, IL, USA; June 3-7, 2011. (2011)

Screening and early detection of pancreatic cancer has the potential to substantially impact outcomes in this deadly disease. Over the last ten years several cohort studies have been conducted and report on the yield of screening in high risk populations. With better understanding of the cellular compartments and the genetic and epigenetic changes that occur, biomarkers have also emerged as promising means of early detection. In this paper we summarize the results of the latest screening cohort and highlight a novel proteomic approach that may be used in future biomarker studies.
Utility of membrane preconcentration-capillary electrophoresis-mass spectrometry in overcoming limited sample loading for analysis of biologically derived drug metabolites, peptides, and proteins (1997)

The limited loading of capillary electrophoresis (CE) leads to relatively poor concentration limits of detection. In this work a unique method for analyte preconcentration with capillary electrophoresis-mass spectrometry (CE-MS) is described. A cartridge containing an impregnated membrane is installed at the inlet of the CE capillary, and we term this approach membrane preconcentration capillary electrophoresis-mass spectrometry (mPC-CE-MS). The analysis of in vivo derived metabolites, peptides, and proteins is described showing the wide applicability of the technology in the analysis of numerous compound classes ranging in molecular weight from 200–60,000 u. In particular, we describe the direct mPC-CE-MS analysis of urine obtained from a patient receiving the neuroleptic drug haloperidol. Three metabolites were found in the urine, and two of them are implicated in the Parkinsonian-like side effects caused by taking this drug. The technique is also applied to the analysis of major histocompatibility complex class I peptides obtained from EG-7 cells. Furthermore, the clinical potential of this approach is described by the direct analysis of urine from a patient suffering from multiple myeloma, as well as aqueous humor derived from a patient undergoing surgery. Finally we show that the use of mPC-ME-MS in conjunction with either analyte stacking (small organic molecules such as metabolites) or moving-boundary transient isotachophoresis (peptides and proteins) after analytes have been eluted from the adsorptive membrane affords optimal performance and no compromise in CE mass spectrometry performance.
Telomerase activation in normal B lymphocytes and non-Hodgkin's lymphomas (1996)

Activation of telomerase seems to be a prerequisite for immortalization and is found in permanent cell lines and most malignant tumors. Normal somatic cells are generally telomerase negative, except for bone marrow stem cells. Weak activity is also present in peripheral blood cells. In the present study strong telomerase activity was demonstrated in vivo in normal mature cells of the immune system, as well as in malignant lymphomas. Benign lymph nodes had lower telomerase activity than benign tonsils, which exhibited intermediate to high activity comparable with findings in malignant lymphomas. In benign tonsils the activity seemed to be restricted to germinal center B cells. In benign lymphoid tissues telomerase activity correlated with B-cell numbers and cell proliferation, but this was not observed in the lymphoma group. High- grade lymphomas exhibited higher levels of telomerase compared with low- grade cases. The data showed that in vivo activation of telomerase is a characteristic feature of germinal center B cells. Different signals for activation of telomerase are likely to exist, one of them being immune stimulation. The data suggest that telomerase activity in malignant lymphomas can be explained by an “induction and retention” model, ie, transformation occurs in a normal, mature B cell with reactivated telomerase, which is retained in the neoplastic clone.
PCSK9 and cancer: Rethinking the link (2021)

To date, PCSK9 has been scantly investigated in cancer. The question that needs to be discussed is "How does PCSK9 act in cancer pathophysiology and what are the risks or benefits associated to its inhibition?". We reviewed the available publications highlighting the contribution of this proprotein convertase in pathways related to cancer, with focus on the potential implications of its long-term pharmacological inhibition in cancer therapy.

A Sensor for Water Detection in Aircraft Adhesive Bondlines (2000)

A simple and low cost sensor for detecting the water ingress in the adhesive bond line was designed. A compressed polypyrrole (PPy) powder was embedded in an epoxy adhesive sandwiched between two aluminium (2024) substrates. Interactions between PPy and water resulted in a rapid increase in resistivity. The DC resistivity increased more than 20 times the initial value when the PPy was contacted by water. The increase was consistent with AC impedance at low frequencies which showed 10 times increase if one PPy disc (3 mm diameter) was embedded or 100 times increase if there were 3 PPy disc embedded when the cell was immersed in a brine solution for approximately 1000 h. The resistivity of compressed PPy embedded in the bondline was unchanged after 2000 h ageing at 100 C. This indicates a good thermal stability. An initial test indicated that the inclusion of a single 5mm diameter PPy disc in a 25mm diameter bonded joint did not significantly decrease the dry adhesive strength of the adhesive joint. These results indicate that the sensor could potentially meet the requirements of a bond degradation sensor in terms of: (1) low cost (few cents for one PPy disc); (2) sensitivity to water; (3) long-term stability; (4) ease of monitoring; and (5) sustaining the dry bond strength.

Geomagnetism of Baked Clay and Recent Sediments K. M. Creer, P. Tucholka and C. E. Barton (eds), Elsevier, North Holland, 1983  28.55 (1984)

A problem with most multi-authored books is an unevenness in the style and quality of the different contributions and a lack of continuity.This book with 40 authors could well have suffered the same criticism.That it does not do so is due in no small measure to the editors who in chapters 1, 2 and 4 give some introductory comments whilst chapter 3 concludes with a discussion by them.The book is then completed in chapter 5 by two of the editors (Professor Creer and Dr Tucholka) and contains a number of different topics and rounds the book off.The result is a very readable, coherent and up-to-date account of the geomagnetism of baked clay and recent sediments.The first chapter gives an account of the magnetization processes involved in baked clay, adobe bricks, and unconsolidated sediments.The second chapter then discusses the various dating techniques -I4C, "OPb and other isotopes, thermoluminescence, tree-rings and varves, and palynology.This sets the stage for the two main chapters of the book -chapter 3 o n the archaeomagnetism of baked clay and chapter 4 on the palaeomagnetism of lake sediments.Together they give a comprehensive account of our present knowledge of the behaviour of the geomagnetic field over post-Glacial and late Glacial time.After an account of the basic techniques for determining the intensity of the archaeomagnetic field and a discussion of the reliability of the measurements, chapter 3 gives the results from Greece, Bulgaria, Yugoslavia, Egypt, the Near East, the USSR, China, Japan, North America, Peru and Australia.This is an extremely valuable compilation of the existing data on the intensity of the ancient magnetic field.After an introductory account of the methods of making palaeomagnetic measurements of lake sediments, results are given from Europe, Central North America, the Great Lakes, Argentina and Australia.The palaeomagnetism of cave sediments is then discussed and chapter 4 ends with an account of the statistical and spectrum analysis of palaeomagnetic data.A feature of the book is the large number of diagrams (more than 100) and the compre-

Analog reflection topology building blocks for adaptive microwave signal processing applications (1995)

The synthesis and realization of an analog-phase shifter, delay line, attenuator, and group delay synthesizer-are presented. These variable control devices are all implemented using the same generic single stage reflection topology. The optimum conditions of operation have been determined and the corresponding group delay behaviors have been investigated to produce simple design equations. As proof-of-concepts, monolithic technology has been used to realize an X-band, phase shifter, delay line, and attenuator. Hybrid technology has been used to realize an L-band, group-delay synthesizer. Because of the high levels of performance measured, these control devices are ideally suited for use as general building blocks in adaptive signal processing applications, including large phased array applications.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
The Influence of Reactant Excess and Film Flexibility on the Mechanism of Nanoparticle Formation in Microemulsions:  A Monte Carlo Simulation (1998)

In this paper we have studied by Monte Carlo simulation the influence of reactant excess (x) and film flexibility (f) on the final size of particles obtained by reaction in microemulsions. We have observed that the ripening mechanism is more significant as reactant excess and film flexibility increase because, when one of the reactants is exhausted, ripening is the only possible way of growth. This gives rise to a faster growth process. Experimental results of particle sizes for different x values agree with the results obtained by simulation, which provides an explanation of the growth mechanism. These results show that both parameters (x and f) are important in order to explain the final size distributions of particles obtained in microemulsions.
