Signal design for bandwidth efficient multiple access with guaranteed bit error rate (2004)

The problem of signal design for bandwidth efficient multiple access is addressed under quality of service (QoS) constraints specified by (possibly different) BER. Indeed, BER more accurately measures the performance than the signal-to-interference ratio (SIR) for uncoded communication. Furthermore, we argue that the asymptotic effective energy (AEE) faithfully characterizes BER, and we translate the BER-specified QoS into AEE-specified ones. We then propose a recursive, greedy algorithm for joint signal design to minimize the system bandwidth while ensuring that each user achieves its desired AEE (and hence BER). This algorithm successfully converts excess power into bandwidth savings under reliability constraints, and significantly improves spectral efficiency over full-rank (e.g. orthogonal) signaling and SIR-based approaches.
The Use of Spin-trapping in the Study of the Mechanisms of Radical Processes (1979)

The review is devoted to the spin-trapping method developed in recent years and used to identify short-lived radicals (mainly in liquid phase) and to investigate the mechanisms of their reactions. Unstable radicals are accepted by a spin-trapping agent with formation of a fairly stable free radical which carries information about its short-lived precursor. The EPR spectra of the resulting spin adducts can be recorded in the liquid phase and are as a rule well resolved. The properties of various spin-trapping agents are described in detail and tables of the parameters of the EPR spectra of the adducts of spin-trapping agents with the trapped radicals are presented. The application of the spin-trapping method in the study of the mechanisms of radical processes in various fields of chemistry is considered. The bibliography includes 161 references.
Use of Growth Hormone and Insulin-Like Growth Factor I in Catabolism That Is Induced by Negative Energy Balance (1993)

Both GH and insulin-like growth factor I (IGF-I) have been shown to promote anabolism in human volunteers that are made catabolic by caloric restriction. We have used caloric restriction as a model of controlled catabolism to test the efficacy of these agents in reversing negative nitrogen balance. Six normal volunteers underwent caloric restriction for 2-week intervals. This restriction induced negative nitrogen balance (e.g. -239 mmol/day). During the second week either IGF-I (16 micrograms/kg h) was administered by intravenous infusion for 16 h, or GH (0.05 mg/kg) was given subcutaneously daily. GH alone improved nitrogen balance by 180 mmol/day, and IGF-I improved it by 175 mmol. The two hormones had opposite effects on carbohydrate metabolism. Mean blood glucose rose approximately 26% with GH whereas it fell 37% with IGF-I and the subjects had frequent hypoglycemic episodes during the infusion. Minimal complications were observed during the 6 days of IGF-I infusion and consisted primarily of edema and jaw pain. It appeared that IGF-I was as efficacious as GH in reversing the negative nitrogen balance induced by caloric restriction and that hypoglycemia induced by IGF-I was the major limiting factor. In a second study 7 volunteers underwent the identical caloric restriction. In contrast to the first study one treatment group received the combination of GH plus IGF-I given in exactly the same doses as in the first study. A second group received IGF-I alone. The combination of GH/IGF-I was much more potent in improving nitrogen balance.(ABSTRACT TRUNCATED AT 250 WORDS)

L0-Sparse DOA Estimation of Close Sources with Modeling Errors (2020)

In the field of array processing, Direction-Of-Arrival (DOA) estimation of close sources in the presence of modeling errors is a challenging problem. Indeed, the degradation of high-resolution methods on such scenario is well known and documented in the literature. This paper proposes an operational sparse L0-regularized method as an alternative. In sparse DOA estimation methods, the determination of the regularization parameter is a critical point, and it is generally empirically tuned. We first provide, in the presence of modeling errors, a theoretical statistical study to estimate the admissible range for this parameter in the presence of two incoming sources. For close sources, we therefore show that the admissible range is shortened. For an operational system, an off-line predetermination of the regularization parameter is required. We show that its selection is closely connected to the resolution limit for a given modeling error. Numerical simulations are presented to demonstrate the efficiency of the proposed implementation and its superiority in comparison with high-resolution methods.
AtNUDX6, an ADP-Ribose/NADH Pyrophosphohydrolase in Arabidopsis, Positively Regulates NPR1-Dependent Salicylic Acid Signaling (2010)

Here, we investigated the physiological role of Arabidopsis (Arabidopsis thaliana) AtNUDX6, the gene encoding ADP-ribose (Rib)/NADH pyrophosphohydrolase, using its overexpressor (Pro35S:AtNUDX6) or disruptant (KO-nudx6). The level of NADH in Pro35S:AtNUDX6 and KO-nudx6 plants was decreased and increased, respectively, compared with that of the control plants, while the level of ADP-Rib was not changed in either plant. The activity of pyrophosphohydrolase toward NADH was enhanced and reduced in the Pro35S:AtNUDX6 and KO-nudx6 plants, respectively. The decrease in the activity of NADH pyrophosphohydrolase and the increase in the level of NADH were observed in the rosette and cauline leaves, but not in the roots, of the KO-nudx6 plants. Notably, the expression level of AtNUDX6 and the activity of NADH pyrophosphohydrolase in the control plants, but not in the KO-nudx6 plants, were increased by the treatment with salicylic acid (SA). The expression of SA-induced genes (PR1, WRKY70, NIMIN1, and NIMIN2) depending on NONEXPRESSOR OF PATHOGENESIS-RELATED GENES1 (NPR1), a key component required for pathogen resistance, was significantly suppressed and enhanced in the KO-nudx6 and Pro35S:AtNUDX6 plants, respectively, under the treatment with SA. Induction of thioredoxin h5 (TRX-h5) expression, which catalyzes a SA-induced NPR1 activation, was suppressed and accelerated in the KO-nudx6 and Pro35S:AtNUDX6 plants, respectively. The expression of isochorismate synthase1, required for the regulation of SA synthesis through the NPR1-mediated feedback loop, was decreased and increased in the KO-nudx6 and Pro35S:AtNUDX6 plants, respectively. Judging from seed germination rates, the KO-nudx6 plants had enhanced sensitivity to the toxicity of high-level SA. These results indicated that AtNUDX6 is a modulator of NADH rather than ADP-Rib metabolism and that, through induction of TRX-h5 expression, AtNUDX6 significantly impacts the plant immune response as a positive regulator of NPR1-dependent SA signaling pathways.

Codon Context Optimization in Synthetic Gene Design (2016)

Advances in de novo synthesis of DNA and computational gene design methods make possible the customization of genes by direct manipulation of features such as codon bias and mRNA secondary structure. Codon context is another feature significantly affecting mRNA translational efficiency, but existing methods and tools for evaluating and designing novel optimized protein coding sequences utilize untested heuristics and do not provide quantifiable guarantees on design quality. In this study we examine statistical properties of codon context measures in an effort to better understand the phenomenon. We analyze the computational complexity of codon context optimization and design exact and efficient heuristic gene recoding algorithms under reasonable constraint models. We also present a web-based tool for evaluating codon context bias in the appropriate context.
AFM Microcantilever With a Collocated AlN Sensor-Actuator Pair: Enabling Efficient Q-Control for Dynamic Imaging (2020)

This manuscript presents a novel microcantilever with an embedded piezoelectric sensor-actuator pair for dynamic atomic force microscopy (AFM). The transducer pair is constructed from a two-layered AlN stack. Stacking the piezoelectric transducers in this manner leads to a minimal feedthrough from actuation to sense electrode, granting a high dynamic range frequency response for dynamic mode AFM. The cantilever's design allows for dual mode operation at 1 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">st</sup> and 2 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">nd</sup> resonance modes. High resolution tapping mode imaging results are reported, while the cantilever is operated at these modes. A feedback control loop is used to modify quality factor of the 1 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">st</sup> mode of the cantilever, using a positive position feedback (PPF) controller. A faster response time is achieved by reducing the Q-factor, enabling the cantilever to track the topography at a higher scan rate. Results of bimodal AFM imaging are reported, using amplitude changes of the 1 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">st</sup> mode for surface topography, while material properties are encoded in phase changes of the 2 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">nd</sup> mode.
High dimensional analyses of cells dissociated from cryopreserved synovial tissue (2018)

Abstract Background Detailed molecular analyses of cells from rheumatoid arthritis (RA) synovium hold promise in identifying cellular phenotypes that drive tissue pathology and joint damage. The Accelerating Medicines Partnership (AMP) RA/SLE network aims to deconstruct autoimmune pathology by examining cells within target tissues through multiple high-dimensional assays. Robust standardized protocols need to be developed before cellular phenotypes at a single cell level can be effectively compared across patient samples. Methods Multiple clinical sites collected cryopreserved synovial tissue fragments from arthroplasty and synovial biopsy in a 10%-DMSO solution. Mechanical and enzymatic dissociation parameters were optimized for viable cell extraction and surface protein preservation for cell sorting and mass cytometry, as well as for reproducibility in RNA sequencing (RNA-seq). Cryopreserved synovial samples were collectively analyzed at a central processing site by a custom-designed and validated 35-marker mass cytometry panel. In parallel, each sample was flow sorted into fibroblast, T cell, B cell, and macrophage suspensions for bulk population RNA-seq and plate-based single cell CEL-Seq2 RNA-seq. Results Upon dissociation, cryopreserved synovial tissue fragments yielded a high frequency of viable cells, comparable to samples undergoing immediate processing. Optimization of synovial tissue dissociation across six clinical collection sites with ∼30 arthroplasty and ∼20 biopsy samples yielded a consensus digestion protocol using 100µg/mL of Liberase TL ™ enzyme. This protocol yielded immune and stromal cell lineages with preserved surface markers and minimized variability across replicate RNA-seq transcriptomes. Mass cytometry analysis of cells from cryopreserved synovium distinguished: 1) diverse fibroblast phenotypes, 2) distinct populations of memory B cells and antibody-secreting cells, and 3) multiple CD4+ and CD8+ T cell activation states. Bulk RNA sequencing of sorted cell populations demonstrated robust separation of synovial lymphocytes, fibroblasts, and macrophages. Single cell RNA-seq produced transcriptomes of over 1000 genes/cell, including transcripts encoding characteristic lineage markers identified. Conclusion We have established a robust protocol to acquire viable cells from cryopreserved synovial tissue with intact transcriptomes and cell surface phenotypes. A centralized pipeline to generate multiple high-dimensional analyses of synovial tissue samples collected across a collaborative network was developed. Integrated analysis of such datasets from large patient cohorts may help define molecular heterogeneity within RA pathology and identify new therapeutic targets and biomarkers.
Cryptogenic fulminant hepatic failure in infancy: Report of 2 cases with unique vascular obstructive changes in native livers (2006)

Although the causes of fulminant hepatic failure (FHF) remain cryptogenic in many cases, a few reports have reviewed the pathological findings of native livers to evaluate the etiology. We report 2 cases of infantile cryptogenic FHF with unique vascular obstructive changes in the native livers. Clinically, it was notable that these 2 patients developed FHF very early in life, at 2 months and 5 months of age, respectively. One patient died from chronic rejection associated with hepatic veno-occlusive disease 4 months after transplantation. Histologically, hepatocytes in the native livers were completely destroyed in both patients, and vascular findings revealed obstruction of central veins in 1 patient and obstruction of portal veins in the other patient. Although the pathogenesis of vascular obstructions is not yet understood, this study suggests that an obstructive vascular event may be a contributing etiologic factor of FHF in infancy.

<title>Visualization and analysis of three-dimensional transonic flows by holographic interferometry</title> (1992)

Holographic interferometry has been used in a large scale transonic wind tunnel to produce a 3D flow visualization. The experiments have been carried out on a model civil transport aircraft wing and turbine powered engine simulator combination. This study is significant industrially as the method forms a diagnostic for turbofan installations. The holograms show many relevant flow features including shock waves, flow interactions between the engine simulator flow and the freestream flow, secondary flows, and acoustic waves. Quantitative 3D position information has also been obtained for some of these features. A comparison to other flow diagnostic methods has been made in this paper.

Membrane resistance increases when automaticity develops in explanted rat heart cells (1990)

We compared the passive electrical properties of isolated ventricular myocytes (resting potential -65 mV, fast action potentials, and no spontaneous activity) with those of 2- to 7-day-old cultured ventricle cells from neonatal rats (resting potential -50 mV, slow action potentials, and presence of spontaneous activity). In myocytes the specific membrane capacity was 0.99 microF/cm2, and the specific membrane resistance increased from 2.46 k omega.cm2 at -65 mV to 7.30 k omega.cm2 at -30 mV. In clusters, the current-voltage relationships measured under current-clamp conditions showed anomalous rectification and the input resistance decreased from 1.05 to 0.48 M omega when external K+ concentration was increased from 6 to 100 mM. Using the model of a finite disk we determined the specific membrane resistance (12.9 k omega.cm2), the effective membrane capacity (17.8 microF/cm2), and the lumped resistivity of the disk interior (1,964 omega.cm). We conclude that 1) the voltage dependence of the specific membrane resistance cannot completely explain the membrane resistance increase that accompanies the appearance of spontaneous activity; 2) a decrease of the inwardly rectifying conductance (gk1) is mainly responsible for the increase in the specific membrane resistance and depolarization; and 3) approximately 41% of the inward-rectifying channels are electrically silent when spontaneous activity develops in explanted ventricle cells.
Investigations on the Use of Fluorescence Dyes for Labeling Dendrimers: Cytotoxicity, Accumulation Kinetics, and Intracellular Distribution (2010)

Fluorescent dyes (e.g., dansyl, fluoresceine isothiocyanate, or naphthalimide groups) are widely used as markers to study biological properties of drugs. In order to evaluate possible mediated cytotoxicity, we attached three molecules each to 1,3,5-tris(3-propylamino)benzene initially synthesized as core molecule for the design of dendrimers. Cytotoxic effects were only observed for the NO(2)-substituted naphthalimide conjugate. The intracellular distribution was visualized via confocal fluorescence microscopy and pointed to an accumulation in the endosome or nucleus, dependent on the cell line used.
Strength Analysis of Precast Bridge Decks with Full-Depth Precast Overhang Panels (2010)

The use of full-depth precast overhang panels provides an alternative to modern bridge deck construction by eliminating the need to form a full-depth cast-in-place (CIP) overhang. Additional benefits from these precast panels include improving worker safety conditions during construction and accelerating construction. To validate the capacity of a full-depth precast bridge deck system compared with a conventionally constructed concrete bridge deck, the Texas Department of Transportation sponsored an experimental investigation. For both, the failure loads exceeded the maximum factored 2007 AASHTO load and resistance factor design for decks and deck overhangs. Observations suggest that there is an interaction between flexure and shear to estimate the capacity of full-depth concrete bridge deck overhangs or slabs constructed with stay-in-place (SIP) panels and a CIP topping. This paper shows how a modified yield line theory, which accounts for the development length of the mild steel reinforcing to reach yield strength, is used to analyze precast bridge decks with full-depth precast overhang panels. For the full-depth overhangs, the internal work equation is further modified to allow for the panel-to-panel seam that exists within the system. At the interior portions of the bridge deck, a compound shear–flexure mechanism is proposed. This is an additive model of a flexural yield line failure in the lower SIP precast panels and punching shear in the upper CIP portion of the deck. Therefore, a strength method of analysis is used to design the exterior portion (overhang) that incorporates the concurrent effects of flexure and shear in panelized precast deck systems.
Knowledge extraction from event-driven metering of electrical consumption patterns (2016)

This paper discusses the conceptual and practical implications of adopting a new type of energy meter, based on the identification of events from measuring the power pattern and on sending information on the actual energy used in the time interval between two events. The event-driven metering (EDM) approach enables gathering data useful for setting up effective representations of the knowledge that can be extracted about the prosumers' energy usage during time. Specific comparisons between the EDM effectiveness in reconstructing the power patterns with respect to the classical time-driven metering at regular time intervals are introduced to show the remarkable advantages of the EDM approach. An enhanced average power pattern reconstruction mechanism is also presented, based on the direct reproduction of the average power at the fastest time step occurring before the event generation, and on averaging the power pattern for the remaining part of the corresponding time interval. The case study application is illustrated by using the highly variable power pattern of a residential user.
Double gate n-type WSe2 FETs with high-k top gate dielectric and enhanced electrostatic control (2018)

We propose and experimentally demonstrate double-gated n-type WSe <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> FETs with excellent top gate high-k dielectric layer. Under back gate control, the devices behave as n-type enhancement transistors, with ON/OFF current ratios larger than 6 orders of magnitude and a ON current close to 1 pA/μm under a drain bias of 100 mV. Negative top gate biases determine a much steeper turn-on of the back gated transfer characteristic and a reduction of the hysteresis. Top gated device behaves as n-type depletion FETs, exhibiting a I <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">ON</sub> /I <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">OFF</sub> ratio larger than 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">6</sup> under positive bias applied to the back gate.
