Boosting theoretical zeolitic framework generation for the determination of new materials structures using GPU programming (2011)

Evolutionary algorithms have proved to be efficient for solving complicated optimization problems. On the other hand, the many-core architecture in graphical cards "General Purpose Graphic Processing Unit" (GPGPU) offers one of the most attractive cost/performance ratio. Using such hardware, the manuscript shows how an efficiently implemented genetic algorithm with a simple fitness function allows boosting the determination of zeolite structures. A case study is presented.
Privacy Preserving Image Queries for Camera Localization (2019)

Augmented/mixed reality and robotic applications are increasingly relying on cloud-based localization services, which require users to upload query images to perform camera pose estimation on a server. This raises significant privacy concerns when consumers use such services in their homes or in confidential industrial settings. Even if only image features are uploaded, the privacy concerns remain as the images can be reconstructed fairly well from feature locations and descriptors. We propose to conceal the content of the query images from an adversary on the server or a man-in-the-middle intruder. The key insight is to replace the 2D image feature points in the query image with randomly oriented 2D lines passing through their original 2D positions. It will be shown that this feature representation hides the image contents, and thereby protects user privacy, yet still provides sufficient geometric constraints to enable robust and accurate 6-DOF camera pose estimation from feature correspondences. Our proposed method can handle single- and multi-image queries as well as exploit additional information about known structure, gravity, and scale. Numerous experiments demonstrate the high practical relevance of our approach.

A MEMS resonant strain sensor operated in air (2004)

This paper describes a double-ended tuning fork (DETF) strain sensor that operates in resonance at atmospheric pressure. The sensor was driven with non-integrated, surface mount electronics that successfully mitigates the effects of feed-through capacitance. The MEMS strain sensor achieves a resolution of 0.1 microstrain (/spl mu//spl epsiv/) in a bandwidth of 10 Hz to 20 kHz. The measured phase noise floor at 300 Hz offset from the resonant frequency (217 kHz) is -100 dBc/Hz and the Allan variance for time intervals of 2 seconds is 0.0043 Hz. The measured strain sensitivity is 39 Hz//spl mu//spl epsiv/. These results are commensurate with current state-of-the-art sensors that are integrated with electronics and packaged in vacuum.
Online Monitoring of Water Toxicity by Use of Bioluminescent Reporter Bacterial Biochips (2011)

We describe a flow-through biosensor for online continuous water toxicity monitoring. At the heart of the device are disposable modular biochips incorporating agar-immobilized bioluminescent recombinant reporter bacteria, the responses of which are probed by single-photon avalanche diode detectors. To demonstrate the biosensor capabilities, we equipped it with biochips harboring both inducible and constitutive reporter strains and exposed it to a continuous water flow for up to 10 days. During these periods we challenged the biosensor with 2-h pulses of water spiked with model compounds representing different classes of potential water pollutants, as well as with a sample of industrial wastewater. The biosensor reporter panel detected all simulated contamination events within 0.5-2.5 h, and its response was indicative of the nature of the contaminating chemicals. We believe that a biosensor of the proposed design can be integrated into future water safety and security networks, as part of an early warning system against accidental or intentional water pollution by toxic chemicals.
Advanced method for run-to-run control of photolithography overlay registration in high-mix semiconductor production (2005)

The application of overlay run-to-run control in high-mix production fabs (such as development fabs, ASIC fabs or foundries) encounters some unique problems. A new observer algorithm called JADE<sup>TM </sup>(Just-in-Time Adaptive Disturbance Estimation) was developed to solve the high-mix run-to-run control problem. JADE uses recursive weighted least-squares parameter estimation to identify the contributions to variation that are dependent upon tool, product, reference tool, and reference reticle. With the JADE Observer algorithm, run-to-run controllers use all available feedback data independent of the length of time since a particular product was processed. The application of JADE, compared to traditional control techniques, will be demonstrated on high and low-mix fab lithography overlay data. This comparison illustrates the degradation of the typical streamline observer formulation under high-mix operation, with an actual worsening of overlay control relative to open-loop (no run-to-run control) operation. In contrast, the JADE algorithm control performance, while matching the typical streamline formulation at low-mix operation, will be shown to be unaffected under very high-mix photolithography operation.

Designing for serendipity (2002)

The future world of ubiquitous computing is one in which we will be surrounded by an ever-richer set of networked devices and services. In such a world, we cannot expect to have available to us specific applications that allow us to accomplish every conceivable combination of devices that we might wish. Instead, we believe that many of our interactions will be through highly generic tools that allow enduser discovery, configuration, interconnection, and control of the devices around us. This paper presents a design study of such an environment, intended to support serendipitous, opportunistic use of discovered network resources. We present an examination of a generic browser-style application built on top of an infrastructure developed to support arbitrary recombination of devices and services, as well as a number of challenges we believe to be inherent in such settings.
Development of transparent single-crystalline KNbO3thin film by LPE technique (2004)

Single-crystalline KNbO3 thin film has been successfully formed on SrTiO3 substrate from high-temperature K2CO3–Nb2O5 solution by the liquid phase epitaxy (LPE) technique. The growth morphology was strongly influenced by the melt composition and film growth temperature. The starting material for the film preparation was a powder mixture of K2CO3 and Nb2O5. The oxides were mixed in non-stoichiometric proportion with excess K2CO3 as flux. Under the optimized film growth conditions using melt compositions including K2CO3/Nb2O5Z52.5/47.5, 60.0/40.0 and 65.0/35.0, transparent single-crystalline KNbO3 thin films could be obtained. The synthesized KNbO3 thin film was subjected to precession X-ray photography in order to evaluate the crystallographic relationship with SrTiO3 substrate, and the result was compared with a simulated diffraction pattern. The precession X-ray photography clearly indicated that the [010]KNbO3 is not placed on the same diffraction line as [010]SrTiO3 but is slightly shifted with a difference in angle of approximately 38, while the [100] and [001] agree in direction for KNbO3 and SrTiO3. The observed lattice parameter c of KNbO3 film was calculated to be4.043 Å which was slightly (1.7%) larger than 3.974 Å reported for KNbO3 bulk crystal. In-plane rotation and elongation toward substrate normal for KNbO3 lattice on SrTiO3 substrate were discussed from the viewpoint of release of elastic energy accumulated by lattice mismatch on the substrate. © 2004 Elsevier Ltd.

Bringing Greater Accuracy to Europe’s Healthcare Systems: The Unexploited Potential of Biomarker Testing in Oncology (2020)

Rapid and continuing advances in biomarker testing are not being matched by take-up in health systems, and this is hampering both patient care and innovation. It also risks costing health systems the opportunity to make their services more efficient and, over time, more economical. This paper sets out the potential of biomarker testing, the unfolding precision and range of possible diagnosis and prediction, and the many obstacles to adoption. It offers case studies of biomarker testing in breast, ovarian, prostate, lung, thyroid and colon cancers, and derives specific lessons as to the potential and actual use of each of them. It also draws lessons about how to improve access and alignment, and to remedy the data deficiencies that impede development. And it suggests solutions to outstanding issues - notably including funding and the tangled web of obtaining reimbursement or equivalent coverage that Europe's fragmented health system implies. It urges a European evolution towards an initial minimum testing scenario, which would guarantee universal access to a suite of biomarker tests for the currently most common conditions, and, further into the future, to an optimum testing scenario in which a much wider range of biomarker tests would be introduced and become part of a more sophisticated health system articulated around personalised medicine. For exploiting genomics to the full, it argues the need for a new policy framework for Europe. Biomarker testing is not an issue that can be treated in isolation, since the purpose of testing is to improve health. Its use is therefore always closely linked to specific health challenges and needs to be viewed in the broader policy context in the EU and more widely. The paper is the result of extensive engagement with experts and decision makers to develop the framework, and consequently represents a wide consensus of views on how healthcare systems should respond from push and pull factors at local, national and cross-border and EU level. It contains strong views and clear recommendations springing from the convictions of patients, clinicians, academics, medicines authorities, HTA bodies, payers, the diagnostic, pharmaceutical and ICT industries, and national policy makers.
Individuals with Pulmonary Tuberculosis Have Lower Levels of Circulating CD1d‐Restricted NKT Cells (2007)

Mycobacterium tuberculosis (MTB) is a leading cause of mortality worldwide from an infectious agent. Natural killer T (NKT) cells recognize mycobacterial antigens and contribute to anti-MTB immunity in mouse models. NKT cells were measured in subjects with pulmonary tuberculosis, MTB-exposed individuals, and healthy controls. NKT cell levels are selectively lower in peripheral blood mononuclear cells from individuals with pulmonary tuberculosis than in both MTB-exposed subjects and healthy control subjects. This apparent loss of NKT cells from the peripheral blood is sustained during the 6 months after the initiation of MTB treatment. These findings indicate that NKT cells may be an important component of antituberculosis immunity.
Analysis and Design of Efficient and Flexible Fast-Convolution Based Multirate Filter Banks (2014)

In this paper, we investigate fast-convolution based highly tunable multirate filter bank (FB) configurations. Based on FFT-IFFT pair with overlapped processing, they offer a way to tune the filters' frequency-domain characteristics in a straightforward way. Different subbands are easily configurable for different bandwidths, center frequencies, and output sampling rates, including also partial or full-band nearly perfect-reconstruction systems. Such FBs find various applications, for example, as flexible multichannel channelization filters for software defined radios. They have also the capability to implement simultaneous waveform processing for multiple single-carrier and/or multicarrier transmission channels with nonuniform bandwidths and subchannel spacings. This paper develops an effective model for frequency response analysis and optimization for such filter banks, explores various practical issues of fast-convolution processing and reports the optimized frequency response characteristics versus direct raised cosine based designs. The fast-convolution approach is shown to be a competitive basis for filter bank based multicarrier waveform processing in terms of spectral containment and complexity.
Back Cover: Conversion of (Ligno)Cellulose Feeds to Isosorbide with Heteropoly Acids and Ru on Carbon (ChemSusChem 1/2013) (2013)

The back cover picture shows the sequential steps for the conversion of wheat straw to isosorbide: organosolv pretreatment of wheat straw to delignified pulp followed by one-pot hydrolytic hydrogenation and dehydration to isosorbide with heteropoly acids and Ru/C, as described by Sels et al. on page 199. The carbon cycle is tentatively closed via CO2 uptake from the end products (e.g. polymers, surfactants) by the wheat plants.
Restricted expression of the neuronal intermediate filament protein plasticin during zebrafish development (1998)

In the adult goldfish visual pathway, expression of the neuronal intermediate filament (nIF) protein plasticin is restricted to differentiating retinal ganglion cells (RGCs) at the margin of the retina. Following optic nerve injury, plasticin expression is elevated transiently in all RGCs coincident with the early stages of axon regeneration. These results suggest that plasticin may be expressed throughout the nervous system during the early stages of axonogenesis. To test this hypothesis, we analyzed plasticin expression during zebrafish (Danio rerio) neuronal development. By using immunocytochemistry and in situ hybridization, we found that plasticin is expressed in restricted subsets of early zebrafish neurons. Expression coincides with axon outgrowth in projection neurons that pioneer distinct axon tracts in the embryo. Plasticin is expressed first in trigeminal, Rohon-Beard, and posterior lateral line ganglia neurons, which are among the earliest neurons to initiate axonogenesis in zebrafish. Plasticin is expressed also in reticulospinal neurons and in caudal primary motoneurons. Together, these neurons establish the first behavioral responses in the embryo. Plasticin expression also coincides with initial RGC axonogenesis and progressively decreases after RGC axons reach the tectum. At later developmental stages, plasticin is expressed in a subset of the cranial nerves. The majority of plasticin-positive neurons are within or project axons to the peripheral nervous system. Our results suggest that plasticin subserves the changing requirements for plasticity and stability during axonal outgrowth in neurons that project long axons.
Micromotor technology: electric drive designer's perspective (2002)

Some insight as to the application of modern electric drive expertise to micro-scale electric machines is given. The discussion is supported by a summary of current micromotor technology and some calculations involving fundamental scaling issues. The main conclusions are: (1) that despite recent advances in magnetic micromachines, electrostatic machines are still the most viable; and (2) that considerable insight from drives experts can be offered in either case.
Detection of Rheumatoid Arthritis–Interstitial Lung Disease Is Enhanced by Serum Biomarkers (2015)

Clinical risk factors and autoantibodies are strongly associated with the presence of clinically evident and subclinical RA-ILD on computed tomography scan in two independent RA cohorts. A biomarker signature composed of matrix metalloproteinase 7, pulmonary and activation-regulated chemokine, and surfactant protein D significantly strengthens this association. These findings may facilitate identification of RA-ILD at an earlier stage, potentially leading to decreased morbidity and mortality.
Development of Three-Dimensional Hot Bending and Direct Quench using robot (2015)

The Use of Polydisulfides and Copolymeric Disulfides in the Li/PEO/SRPE Battery System (1992)

Solid redox polymerization electrodes (SRPEs) have recently been used successfully as cathodes in lithium solid polymer electrolyte batteries. SRPEs contain organopolydisulfides, , as the electroactive material; upon cell discharge these materials are reductively depolymerized via scission of the disulfide linkages to di‐ or trithiolate salts. The thiolate salts are reoxidized to the polymeric disulfides when the cell is recharged. Organopolydisulfides are easily synthesized via a one‐step process, are inexpensive, and exhibit high performance levels in batteries. A characteristic unique to the SRPE is the facile modification of physical and electrochemical properties simply by changing the organic group R, or the ability to combine the desirable features of several compounds by copolymerization. The discharge characteristics of several different polymeric and copolymeric disulfides are presented in this paper. In general aliphatic organopolydisulfides exhibit a flat discharge potential of about 2 V vs. Li, while others have higher cell voltages. The low equivalent weight and the high utilization of thick cathodes of (X8) translate into high energy densities for lithium polymer electrolyte cells.
Transient Sox9 Expression Facilitates Resistance to Androgen-Targeted Therapy in Prostate Cancer (2020)

Developmentally reprogrammed prostate cancer cell models recapitulate features of clinically advanced prostate tumors, including downregulated Rb1/p53 and overexpression of Sox2 with Sox9. Sox9 is a marker of a transitional state that identifies prostate cancer cells under the stress of therapeutic assault and facilitates progression to therapy resistance. Its expression may index the relative activity of the NF-κB pathway.
Technology adaption in logic synthesis (1986)

Systems which synthesize logic implementations from specifications have moved, under the pressure of production requirements, from Boolean minimizers to procedures attempting to satisfy a wider range of criteria. Gate or cell count, taken as a measure of area, continues to be a major factor in design acceptability, but timing constraints, testability, wirability, and efficient use of available primitives are important as well. Additional information, such as “don't care” conditions, can be used to improve the design quality. This paper describes how these requirements are specified to and enforced by the Logic Synthesis System (LSS), a tool which has been used in production on gate array chips. Trade-offs between varying requirements, and their effect on the logic produced, are discussed and illustrated with a standard set of examples.
Femtosecond spectroscopic studies of the ultrafast relaxation process in the charge-transfer state of insulating cuprates (1994)

We have investigated the transient absorption spectra of insulating ${\mathrm{YBa}}_{2}$${\mathrm{Cu}}_{3}$${\mathrm{O}}_{\mathit{y}}$ and ${\mathrm{Nd}}_{2}$${\mathrm{CuO}}_{4}$ thin films by the pump and probe method from 1.3 to 2.8 eV with a time resolution of 100 fs. For both insulating samples, a bleaching signal with a 0.6--0.9 ps initial decay time was observed in the spectral range of the ${\mathrm{O}}_{2\mathit{p}}$ to ${\mathrm{Cu}}_{3\mathit{d}}$ charge-transfer transition at around 1.8 eV. This initial decay can be explained as a nonradiative transition through the successive emission of magnons having a comparably large energy quantum. In the photon-energy region lower than the bleaching signal, an induced absorption signal is observed. The origin of the induced absorption by pumping pulses has not necessarily been resolved, but the in-gap states induced by the photodoping effect is suggested as a reason.
Visualization of flow in multiple-scattering liquids (1996)

We have performed quasi-elastic multiple-light-scattering experiments on a suspension of colloidal particles in Brownian motion into which a capillary with Poiseuille flow of the same suspension was inserted. We show that the time correlation function of the backscattered light, measured at various points on the sample surface, provides information on the position of the capillary and on the flow rate, demonstrating the possibility of imaging flow in turbid media under conditions of no static scattering contrast.
Fabrication and Characterization of Stop Flow Valves for Fluid Handling (2003)

Monolithic stop flow valves produced by Deep Reactive Ion Etching (DRIE) are proposed for the handling and the processing of small metered fluid volumes in capillary channels. A 2 /spl mu/l sampling unit has been successfully integrated as an element of a miniaturized chemical analysis system to improve analysis reproducibility. The net pressure needed to overcome the stop flow valve was determined experimentally for different valve diameters and compared to theoretical values. A 60 /spl mu/m diameter valve diameter can typically withstand a water pressure head of 20 cm, which is largely sufficient for most applications. Sampling of 2 /spl mu/l of selection of solvents was successfully demonstrated.
