Stretchable Piezoelectric Sensing Systems for Self‐Powered and Wireless Health Monitoring (2019)

Abstract Continuous monitoring of human physiological signals is critical to managing personal healthcare by early detection of health disorders. Wearable and implantable devices are attracting growing attention as they show great potential for real‐time recording of physiological conditions and body motions. Conventional piezoelectric sensors have the advantage of potentially being self‐powered, but have limitations due to their intrinsic lack of stretchability. Herein, a kirigami approach to realize a novel stretchable strain sensor is introduced through a network of cut patterns in a piezoelectric thin film, exploiting the anisotropic and local bending that the patterns induce. The resulting pattern simultaneously enhances the electrical performance of the film and its stretchability while retaining the mechanical integrity of the underlying materials. The power output is enhanced from the mechano‐electric piezoelectric sensing effect by introducing an intersegment, through‐plane, electrode pattern. By additionally integrating wireless electronics, this sensing network could work in an entirely battery‐free mode. The kirigami stretchable piezoelectric sensor is demonstrated in cardiac monitoring and wearable body tracking applications. The integrated soft, stretchable, and biocompatible sensor demonstrates excellent in vitro and ex vivo performances and provides insights for the potential use in myriad biomedical and wearable health monitoring applications.
Roles of the Enantioselective Glutathione <i>S</i> -Transferases in Cleavage of β-Aryl Ether (2003)

Cleavage of the beta-aryl ether linkage is the most important process in lignin degradation. Here we characterize the three tandemly located glutathione S-transferase (GST) genes, ligF, ligE, and ligG, from low-molecular-weight lignin-degrading Sphingomonas paucimobilis SYK-6, and we describe the actual roles of these genes in the beta-aryl ether cleavage. Based on the identification of the reaction product by electrospray ionization-mass spectrometry, a model compound of beta-aryl ether, alpha-(2-methoxyphenoxy)-beta-hydroxypropiovanillone (MPHPV), was transformed by LigF or LigE to guaiacol and alpha-glutathionyl-beta-hydroxypropiovanillone (GS-HPV). This result suggested that LigF and LigE catalyze the nucleophilic attack of glutathione on the carbon atom at the beta position of MPHPV. High-pressure liquid chromatography-circular dichroism analysis indicated that LigF and LigE each attacked a different enantiomer of the racemic MPHPV preparation. The ligG gene product specifically catalyzed the elimination of glutathione from GS-HPV generated by the action of LigF. This reaction then produces an achiral compound, beta-hydroxypropiovanillone, which is further degraded by this strain. Disruption of the ligF, ligE, and ligG genes in SYK-6 showed that ligF is essential to the degradation of one of the MPHPV enantiomers, and the alternative activities which metabolize the substrates of LigE and LigG are present in this strain.
Detection of thermal waves through modulated optical transmittance and modulated optical scattering (1986)

We show that variations in local optical constants induced by the presence of thermal waves can be used for thermal wave detection and analysis through measurements of thermal wave-induced modulated transmittance and scattering.

Electrochemical preparation of a metallic polythiophene film (1983)

Electrolytic polymerization of thiophene gives a metallic film with a conductivity of ca. 100 S/cm, and which becomes a semiconductive polymer with an optical absorption edge of 2.0 eV when reduced by electrochemical or chemical means.
Detection, Characterization, and Inhibition of FGFR–TACC Fusions in IDH Wild-type Glioma (2015)

Abstract Purpose: Oncogenic fusions consisting of fibroblast growth factor receptor (FGFR) and TACC are present in a subgroup of glioblastoma (GBM) and other human cancers and have been proposed as new therapeutic targets. We analyzed frequency and molecular features of FGFR–TACC fusions and explored the therapeutic efficacy of inhibiting FGFR kinase in GBM and grade II and III glioma. Experimental Design: Overall, 795 gliomas (584 GBM, 85 grades II and III with wild-type and 126 with IDH1/2 mutation) were screened for FGFR–TACC breakpoints and associated molecular profile. We also analyzed expression of the FGFR3 and TACC3 components of the fusions. The effects of the specific FGFR inhibitor JNJ-42756493 for FGFR3–TACC3–positive glioma were determined in preclinical experiments. Two patients with advanced FGFR3–TACC3–positive GBM received JNJ-42756493 and were assessed for therapeutic response. Results: Three of 85 IDH1/2 wild-type (3.5%) but none of 126 IDH1/2-mutant grade II and III gliomas harbored FGFR3–TACC3 fusions. FGFR–TACC rearrangements were present in 17 of 584 GBM (2.9%). FGFR3–TACC3 fusions were associated with strong and homogeneous FGFR3 immunostaining. They are mutually exclusive with IDH1/2 mutations and EGFR amplification, whereas they co-occur with CDK4 amplification. JNJ-42756493 inhibited growth of glioma cells harboring FGFR3–TACC3 in vitro and in vivo. The two patients with FGFR3–TACC3 rearrangements who received JNJ-42756493 manifested clinical improvement with stable disease and minor response, respectively. Conclusions: RT-PCR sequencing is a sensitive and specific method to identify FGFR–TACC–positive patients. FGFR3–TACC3 fusions are associated with uniform intratumor expression of the fusion protein. The clinical response observed in the FGFR3–TACC3–positive patients treated with an FGFR inhibitor supports clinical studies of FGFR inhibition in FGFR–TACC–positive patients.

Reduced interleukin-8 response to Streptococcus pneumoniae by alveolar macrophages from adults with HIV/AIDS (2005)

Reduced interleukin-8 production may result in decreased neutrophil recruitment, and hence increased susceptibility to pneumococcal infection in HIV-infected subjects.
The UI pilot (2005)

In this paper, we introduce the User Interface Pilot, a model-based software tool that enables designers and engineers to create the initial specifications for the pages of a website, or for the screens of a desktop or mobile application. The tool guides the design of these specifications, commonly known as wireframes, in a user-centered fashion by framing the context of the design within the concepts of user tasks, user types, and data objects. Unlike previous model-based tools, the User Interface Pilot does not impose a rigid model-driven methodology and functions well within common software engineering development processes. The tool has been used in over twenty real-world user interface design projects.
PROTON: a policy-based solution for future 4G devices (2004)

We present PROTON, a policy-based solution for 4G mobile devices - it allows users to seamlessly connect to highly integrated heterogeneous wireless networks. The key motivation behind PROTON stems from the statement that handover process complexity will increase in 4G systems, creating the need for augmented knowledge about context, as well as more flexibility. This paper demonstrates (1) how a flexible policy-based approach is suitable for 4G scenarios, and (2) how to incorporate richer context into policies and still maintain a light weight solution appropriate for mobile devices.
A Statistical-Based Approach To Assessing the Fidelity of Combinatorial Libraries Encoded with Electrophoric Molecular Tags. Development and Application of Tag Decode-Assisted Single Bead LC/MS Analysis (2000)

A statistical sampling protocol is described to assess the fidelity of libraries encoded with molecular tags. The methodology, termed library QA, is based on the combined application of tag decode analysis and single bead LC/MS. The physical existence of library compounds eluted from beads is established by comparing the molecular weight predicted by tag decode with empirical measurement. The goal of sampling is to provide information on overall library fidelity and an indication of the performance of individual library synthons. The minimal sampling size n for library QA is l0 x the largest synthon set. Data are reported as proportion (p) +/- lower and upper boundary (lb-ub) computed at the 95% confidence level (alpha = 0.05). As a practical demonstration, library QA was performed on a 25,200-member library of statine amides (size = 40 x 63 x 10). Sampling was conducted three times at n approximately 630 beads per run for a total of 1902 beads. The overall proportions found for the three runs were consistent with one another: p = 84.4%, lb-ub = 81.5-87.2%; p = 83.1%, lb-ub = 80.2-85.95; and p = 84.5%, lb-ub = 81.8-87.3%, suggesting the true value of p is close to 84% compound confirmation. The performance pi of individual synthons was also computed. Corroboration of QA data with biological screening results obtained from assaying the library against cathepsin D and plasmepsin II is discussed.
Managing cache partitioning in multicore processors for certifiable, safety-critical avionics software applications (2014)

Multi-core processors (MCPs) present many challenges to developers of certifiable [1], safety-critical software applications. Many of these challenges fall on the system developer/integrator. However, some rely on capabilities the underlying Real-Time Operating System (RTOS) that is used to support these applications. Most importantly, the RTOS must allow application developers to bound and control interference patterns on shared resources (e.g., contention for shared cache). Additionally, it must help minimize the difference between an application's average and worst-case execution times (ACET and WCET, respectively). Without such RTOS capabilities, developers of certifiable, safety-critical applications will find it difficult to achieve the goals of ensuring that the systems they deliver will safely perform their intended functions and maximizing the available CPU bandwidth afforded by MCPs. In this paper, we discuss cache partitioning technology that allows developers to achieve these two goals along with benchmark results that demonstrate its efficacy.

Lipoarabinomannan of <i>Mycobacterium</i> : Mannose capping by a multifunctional terminal mannosyltransferase (2008)

Biosynthesis of phosphatidylinositol (PI)-containing lipoarabinomannan (LAM) and lipomannan (LM) of Mycobacterium spp. follows a conserved pathway involving multiple membrane-associated, substrate-specific mannosyltransferases (ManTs) responsible for the sequential addition of alpha-mannopyranosyl (Manp) units donated by decaprenyl-P-Manp on the periplasmic side of the plasma membrane. Because of their receptor-binding and immunomodulatory properties, the alpha(1-->2)-linked di- and tri-Manp motifs that functionalize the nonreducing arabinan termini of LAM (ManLAM) in Mycobacterium tuberculosis are of crucial importance. We now show that the M. tuberculosis ManT, Rv2181, is required for the addition of these alpha(1-->2)-linked Manp residues but also at other locations of the LAM molecule. Structural analyses of the LM and LAM variants produced by a M. tuberculosis Rv2181 knockout mutant revealed the presence of but a single Manp residue on the nonreducing arabinan termini of LAM and also a complete absence of alpha(1-->2)-linked Man branching on the mannan backbones of LM and LAM. A recombinant strain was constructed in ManLAM-deficient Mycobacterium smegmatis that coexpressed Rv2181 and Rv1635c-the ManT responsible for the addition of the first Manp capping residue of ManLAM. Analysis revealed LAM termini fully capped with di- and tri-Manp motifs in addition to alpha(1-->2)Man branching on the mannan backbones of LM and LAM, confirming the involvement of the alpha(1-->2)ManT Rv2181 in the dual role of Man capping and mannan-core branching, and in the process generated a rapidly growing, ManLAM-containing strain, a tool for the study of the role of ManLAM in the pathogenesis of tuberculosis.
A proteomic approach to the identification of molecular targets in subsequent apoptosis of HEL cells after diosgenin‐induced megakaryocytic differentiation (2009)

Diosgenin is a plant steroid which is able to induce megakaryocytic differentiation of human erythroleukemia (HEL) cells followed by apoptosis at a later stage. Apoptosis markers and phospho-kinases involved during the subsequent apoptosis of megakaryocytes after diosgenin-induced differentiation in these cells were detected using a proteomic approach. In mature megakaryocytes undergoing apoptosis, we observed increased expression of intrinsic apoptosis markers such as Bax/Bcl-2 ratio and cleaved caspase-9 as well as extrinsic apoptosis markers including cell death receptors and cleaved caspase-8. Furthermore, we demonstrated the link between both apoptotic pathways by Bid cleavage and confirmed the executive phase of apoptosis by caspase-3 cleavage. For the first time, we examined kinase activation and showed that kinases including Src, Tor, Akt, CREB, RSK and Chk2 may be implicated in signalling of subsequent apoptosis of mature megakaryocytes after diosgenin-induced differentiation of HEL cells.
Acoustic properties from logs and discrete measurements (Sites 966 and 967) on Eratosthenes Seamount: controls and ground truth (1998)

Acoustic properties (P-wave velocities, densities, and porosities) and insoluble residues were measured at in situ pressures in 68 core plugs taken from cores recovered at Ocean Drilling Project Sites 966 and 967 and compared with wireline logging data. Study of the parameters that control the acoustic properties and the quality of the logging data reveals: (1) velocity-porosity and velocity-density relationships within the discrete data follow the general trend of the general empirical equation but are offset with respect to it. Insoluble residue and dolomite content are the primary controls on the acoustic velocities of the core plugs, whereas lithologic facies has no or a minor effect; and (2) velocity-porosity and velocity-density relationships in the logging data show considerable deviation and trends that cross those from the general relationships that are believed to approximate fundamental physical principles. Calculated uncertainties in the laboratory measurements are at least one order of magnitude smaller than the difference between laboratory measurements and those from the wireline logs in several intervals. As a consequence, we believe that the downhole wireline measurements are unreliable in large intervals at both sites. Possible causes of the unreliability are poor hole conditions, upscaling effects, and consequent difficulties in making realistic corrections of the raw log data. The wireline logs were found to be of such poor quality that they are untrustworthy sources of acoustic parameters for making synthetic seismograms. This study clearly indicates that logging data should be carefully evaluated and calibrated with petrophysical relationships from literature and from discrete measurements before interpretation or use as input for synthetic seismograms when hole conditions are poor.
Hardware Design of a Digital Synthesizer (1983)

The synthesizer discussed here was designed as a means of generating time-variable spectra by evaluation of algebraic time-dependent functions. In addition to additive synthesis algorithms, many algebraic functions are known that efficiently yield such spectra. The functions themselves are often compact, and they are inherently hardware independent; accordingly, the design strives to reflect these attributes in a straightforward architecture that emphasizes hardware transparency.
Generation of non-Rayleigh speckle distributions using marked regularity models (1999)

Fully developed speckle patterns observed in coherent imagery are characterized by a Rayleigh-distributed envelope amplitude. Non-Rayleigh distributions are observed in many cases, such as when the number of scatterers in a resolution cell is small or scatterers are organized with some periodicity. Distributions resulting from the assumption of random scatterer phase (random walk models) have been used to describe the speckle amplitude in these cases, leading to K, Rician, and homodyned-K amplitude distributions. An alternative is to incorporate nonrandom phase implicitly by adopting models that directly describe the spatial placement of point scatterers. We examine the consequences of assuming that scattering is described in one dimension by a stationary renewal process in which the arrival times are the locations of ideal point scatterers, the interscatterer distances are drawn from a gamma distribution, and the scatterer amplitudes are allowed to be correlated in space. This model has been called the marked regularity model because variations of the model parameters can generate spatial distributions ranging from clustered to random to nearly periodic. We will demonstrate that all of the non-Rayleigh distributions generated by the previous random phase models can also be generated by the marked regularity model, and we show under what conditions the different distributions will result. We also demonstrate that the regularity model is inherently capable of describing certain sparse scattering conditions. Therefore, the model can represent many cases and provide an intuitively pleasing description of the spatial placement of the scatterers.
Improved photoluminescence of organometallic vapor phase epitaxial AlGaAs using a new gettering technique on the arsine source (1983)

Using an aluminum-gallium-indium ternary melt for the removal of oxygen and moisture from the arsine source, substantial improvement in the quality of organometallic vapor phase epitaxial AlGaAs can be achieved. The arsine is bubbled through the ternary melt at room temperature prior to its introduction into a low-pressure reactor. Low-temperature photoluminescence spectra indicate an improvement in the sharpness of the bound exciton transition after the use of this gettering technique.
Ganesha (2010)

Ganesha aims to diagnose faults transparently (in a black-box manner) in MapReduce systems, by analyzing OS-level metrics. Ganesha's approach is based on peer-symmetry under fault-free conditions, and can diagnose faults that manifest asymmetrically at nodes within a MapReduce system. We evaluate Ganesha by diagnosing Hadoop problems for the Gridmix Hadoop benchmark on 10-node and 50-node MapReduce clusters on Amazon's EC2. We also candidly highlight faults that escape Ganesha's diagnosis.

Induced spin polarization and interlayer exchange coupling of the systems Rh/Co(0001) and Ru/Co(0001) (1995)

Spin- and angle-resolved photoemission spectroscopy in an off-normal geometry at h\ensuremath{\nu}=21.2 eV proves that one atomic layer (AL) of Rh or Ru on Co(0001) possesses an induced positive spin polarization at the investigated k point. The oscillatory interlayer exchange coupling in MBE-grown Co/Rh/Co and Co/Ru/Co trilayers has been probed by the spin polarization of the secondary electrons from the top Co layer. The oscillation period lengths found are ${\ensuremath{\lambda}}_{\mathrm{Rh}}$=8\ifmmode\pm\else\textpm\fi{}1 AL and ${\ensuremath{\lambda}}_{\mathrm{Ru}}$=9\ifmmode\pm\else\textpm\fi{}1 AL. In spite of the induced positive spin polarization at the Fermi level the interlayer coupling through Ru and Rh is antiferromagnetic already for an interlayer thickness of 1.5 AL Ru and 2.5 AL Rh.

Risk of fetal loss in twin pregnancies undergoing second trimester amniocentesis (2001)

The risk of early fetal loss in twins undergoing amniocentesis appears to be higher than that of exposed singletons or unexposed twins.
