Dissecting the Cooperative Reassociation of the Regulatory and Catalytic Subunits of cAMP-dependent Protein Kinase (1997)

The catalytic (C) subunit of cAMP-dependent protein kinase requires two distinct surfaces to form a stable complex with its physiological inhibitors, the regulatory (R) subunits and the heat-stable protein kinase inhibitors. In addition to a substrate-like segment that is common to both inhibitors, R requires a peripheral recognition site, PRS2. This surface is comprised of the essential phosphorylation site, Thr-197, His-87, Trp-196, and several surrounding basic residues. To probe the role of Trp-196 in the recognition of R, Trp-196 was replaced with Arg and Ala. Although both rC(W196A) and rC(W196R) were inhibited readily with cAMP-free R, they failed to form an inhibited holoenzyme complex with native R under conditions in which wild-type holoenzyme formed readily. Pairing rC(W196R) with mutant forms of R lacking domain B or having defects in cAMP binding sites A or B highlighted the importance of the conformation of R, and, in particular, the accessibility of site A. One of these mutants, rR(R333K), having a defect in cAMP binding site B formed a stable complex with rC(W196R) in the absence of cAMP. However, unlike wild-type holoenzyme, this complex was active.
Integrated head design using a nanobeak antenna for thermally assisted magnetic recording (2012)

We propose a near-field optical transducer using a triangular antenna and a thin film structure (wing) to efficiently generate an optical near-field near a magnetic head. A finite-difference time-domain calculation showed that the near-field was efficiently generated at the apex of the antenna when the dimensions of the wing were optimized for efficient delivery of the surface plasmon excited on the wing to the antenna. The calculated light utilization efficiency (ratio between the absorbed power in the recording medium and the input power) was 8%. The temperature distribution on the medium, magnetic field distribution, and magnetization pattern were calculated; the proposed recording head may be capable of an areal recording density of 2.5 Tb/in.(2).
One‐Pot Enzymatic Synthesis of Merochlorin A and B (2014)

Abstract The polycycles merochlorin A and B are complex halogenated meroterpenoid natural products with significant antibacterial activities and are produced by the marine bacterium Streptomyces sp. strain CNH‐189. Heterologously produced enzymes and chemical synthesis are employed herein to fully reconstitute the merochlorin biosynthesis in vitro. The interplay of a dedicated type III polyketide synthase, a prenyl diphosphate synthase, and an aromatic prenyltransferase allow formation of a highly unusual aromatic polyketide‐terpene hybrid intermediate which features an unprecedented branched sesquiterpene moiety from isosesquilavandulyl diphosphate. As supported by in vivo experiments, this precursor is furthermore chlorinated and cyclized to merochlorin A and isomeric merochlorin B by a single vanadium‐dependent haloperoxidase, thus completing the remarkably efficient pathway.
Surface-tension-driven liquid–liquid displacement in a capillary (2005)

This paper presents theoretical and experimental studies of the surface-tension-driven, two-immiscible liquid–liquid displacement in a horizontal capillary. Using the dynamic contact angle approach, a one-dimensional mathematical model is developed to describe the capillary displacement of a fixed liquid column by another liquid that continuously flows into the capillary by surface tension. Experiments for a water column displaced by silicon oil were carried out to examine the effect of the water column length and capillary diameter on the displacement dynamics. It was found that a faster and longer displacement is achieved for a shorter water column in a larger capillary. The theoretical predictions agree reasonably well with the experimental studies conducted for the capillary displacement of the silicon oil–water interface. In addition, for a single liquid capillary flow, dimensionless Pi groups are derived using the similarity analysis. It is demonstrated that using the derived Pi groups, the experimental data for the displacement of silicon oil of various viscosities in capillaries of various diameters can collapse into one curve that is consistent with the Washburn equation.

Analisi dei meccanismi di danneggiamento di materiali compositi pultrusi in fibra di vetro tramite emissione acustica e reti neurali (2012)

Il crescente interesse verso i materiali compositi pultrusi rinforzati con fibra di vetro dovuto alle loro interessanti caratteristiche meccaniche e al loro costo ridotto è frenato dalla scarsa conoscenza relativa alle modalità di danneggiamento. Per queste ragioni, prove statiche su provini di questo materiale sono state seguite con misurazioni di emissione acustica, al fine di investigare lo sviluppo del danno sotto l’azione di detti carichi. Alla tecnica sono state affiancate tecniche di classificazione dei segnali (reti neurali e algoritmo k-means) per evidenziare i differenti modi di danneggiamento e la loro evoluzione nel tempo. I risultati ottenuti hanno permesso di validare la tecnica dell’emissione acustica e la classificazione tramite reti neurali come coadiuvante di quest’ultima, per permettere di ottenere maggiori informazioni sulla natura del danneggiamento in corso, anche alla luce dell’utilizzo della tecnica per il monitoraggio strutturale.&#13;\n&#13;\nPultruded glass-fiber reinforced materials are becoming more interesting thanks to their mechanical characteristics and to their reduced costs, but their use is being slowed down by the limited knowledge on their damage modes. For this reason, a study on the static behavior of specimens of this material was carried out together with Acoustic Emission measurements. This technique was supported by signal clustering techniques (neural networks and k-means algorithm) to separate the different damage modes and their evolution in time. The results allowed to validate the Acoustic Emission technique and the neural network classification algorithm, and to obtain more information on the nature of the damage. This will be useful also for the use of the technique for structural monitoring.
The Mizoroki‐Heck Reaction in Tunable Aryl Alkyl Ionic Liquids (2022)

Abstract We report the use of imidazolium based tunable aryl alkyl ionic liquids (TAAILs) as solvents in the Mizoroki–Heck reaction. Different commercially available palladium sources, inorganic bases, TAAILs and reaction conditions were tested for the synthesis of trans ‐stilbene using bromobenzene and styrene. A variety of different stilbene derivatives were synthesized with exclusive formation of the ( E )‐isomers and isolated yields up to 97 %. We were able to optimize the reaction conditions using only 0.25 mol% of Pd(OAc) 2 as the catalyst and a reaction time of 4 hours. No additional ligands or additives are used in the reaction. The catalytic system using TAAILs achieved higher yields than commercially available imidazolium and phosphonium ionic liquids, demonstrating the potential of tailored ionic liquids as a reaction medium for the Mizoroki–Heck reaction.
1D numerical study of a multistage centrifugal pump during transient operation (2022)

Abstract Hydropower plants (HPPs) are acknowledged to be fundamental assets to provide generation flexibility to power systems hosting substantial amount of stochastic renewable energy sources. Within this context, providing this flexibility enforces HPP units to cross-over transient operating conditions or to operate in off-design conditions. The evaluation of the impact that such transients have on the hydraulic machines is a fundamental step to assess the operating costs in terms of lifetime reduction of the machine structural integrity. When these assessments are performed on experimental test-rigs featuring a machine’s reduced scale models, testing transient regimes may potentially trigger harmful pressure profiles along the piping system as well as resonant phenomena on the test-rig. Simulating how the several state variables evolve during the experimental tests allows for the prediction of damaging circumstances and, eventually, prevent performing experimental tests in detrimental conditions. In this regard, this paper illustrates a numerical method able to reliably reproduce the experimental test-rig behavior while preserving the consistency of the scaled similarities with respect to a specific case study HPP: the Veytaux I pumped-storage hydropower plant located in Switzerland. Moreover, in this paper, the developed 1D numerical model of the EPFL Technological Platform for Hydraulic Machines experimental test-rig is presented since some of the characteristic transient sequences of the studied HPP are simulated on this model and compared to the prototype scale 1D numerical results.
Longitudinal Morphological and Physiological Monitoring of Three-dimensional Tumor Spheroids Using Optical Coherence Tomography (2019)

Tumor spheroids have been developed as a three-dimensional (3D) cell culture model in cancer research and anti-cancer drug discovery. However, currently, high-throughput imaging modalities utilizing bright field or fluorescence detection, are unable to resolve the overall 3D structure of the tumor spheroid due to limited light penetration, diffusion of fluorescent dyes and depth-resolvability. Recently, our lab demonstrated the use of optical coherence tomography (OCT), a label-free and non-destructive 3D imaging modality, to perform longitudinal characterization of multicellular tumor spheroids in a 96-well plate. OCT was capable of obtaining 3D morphological and physiological information of tumor spheroids growing up to about 600 µm in height. In this article, we demonstrate a high-throughput OCT (HT-OCT) imaging system that scans the whole multi-well plate and obtains 3D OCT data of tumor spheroids automatically. We describe the details of the HT-OCT system and construction guidelines in the protocol. From the 3D OCT data, one can visualize the overall structure of the spheroid with 3D rendered and orthogonal slices, characterize the longitudinal growth curve of the tumor spheroid based on the morphological information of size and volume, and monitor the growth of the dead-cell regions in the tumor spheroid based on optical intrinsic attenuation contrast. We show that HT-OCT can be used as a high-throughput imaging modality for drug screening as well as characterizing biofabricated samples.
Corrected pose data for the Wright Patterson Air Force Base 2009 Wide Area Motion Imagery data set (2015)

The Wright Patterson Air Force Base 2009 Wide Area Image data set consists of 1537 frames of high-resolution image data. The data are supplied as raw images with pose files and also as projected images in National Imagery Transmission Format (NITF). The georegistration performance of the NITF images is 22.3 m root-mean square horizontal (RMSH). In a previous paper, calibrated camera models were developed to reduce the georegistration error to 3.3 m RMSH. In this work, corrected pose files are generated to reduce the error to 0.9 m RMSH. This is done by correcting the pose errors in a stepwise fashion to illustrate the error sources, which are global positioning system position bias, time registration errors, and attitude errors. The pose files are then corrected by simultaneously modifying the position and attitude to achieve the 0.9 m RMSH result. The corrected pose files are posted to allow users to perform high-accuracy projection, tracking, and other functions.
APROS: Algorithmic Development Methodology for Discrete-Continuous Optimization Problems (1989)

APROS represents an algorithmic development procedure for classes of mathematical programming problems that involve some form of decomposition technique and require extensive communication of data between a set of subproblems whose sizes and structures may vary during the solution procedure. Examples include most classes of mixed-integer nonlinear programming problems and large-scale mixed-integer linear programming problems as well as a wide variety of algorithms for large-scale nonlinear and linear programming problems exhibiting special structure. APROS works through the General Algebraic Modeling System (GAMS) to provide exact syntactic statement of algorithmic solution procedures. APROS procedures are implemented through GAMS which is interfaced with nonlinear, linear and mixed-integer linear programming solvers to provide completely general automated implementations of many well known algorithms including the Generalized Benders Decomposition, the Outer Approximation/Equality Relaxation and Dantzig-Wolfe Decomposition. The flexibility of APROS and the highly procedural modeling language GAMS provide a means of obtaining quick solutions to difficult classes of problems by implementing a selected algorithm, and also provide a unique tool for developing, prototyping and experimenting with new algorithms. A description of the procedural components, features and setups is presented with emphasis on the generality of the techniques.
High Q dielectric resonators using YBa/sub 2/Cu/sub 3/O/sub x/ thick films and polycrystalline dielectrics (1997)

The combination of high Q dielectric resonators and high temperature superconducting (HTS) films offer many advantages in the area of cellular and satellite communications. The high cost of single crystal dielectrics and HTS thin films may be unattractive in certain applications. Superconducting thick films and polycrystalline ceramic dielectrics offer a high performance, low cost alternative to high Q thin film/single crystal dielectric resonators. Results on polycrystalline dielectrics show that Q's well in excess of 10/sup 5/ at 10 GHz and 77 K can be achieved in a design made compact by the use of a HTS thick film shield.
Effects of natural and synthetic pigments in diets on flesh coloration and growth of rainbow trout (Oncorhynchus mykiss W.) (2005)

The desired pink to red color of rainbow trout flesh (Oncorhynchus mykiss W.) can be obtained by adding carotenoids to the fish diet. This study was conducted to determine the effects on growth and color retention of natural pigments (30 ppm red pepper meal, 60 ppm red pepper meal, 30 ppm shrimp by-products meal, 60 ppm shrimp by-products meal), synthetic carotenoids (30 ppm astaxanthin, 60 ppm astaxanthin), and a control group (no added pigment). Duplicates of each of the seven treatments were reared for three months. The best specific growth rates were obtained with 30 ppm astaxanthin (0.83%) and 60 ppm red pepper meal (0.84%); the low- est was in the control (0.54%). The lowest food conversion ratio was obtained with 30 ppm astax- anthin (1.38) and highest in the control (2.23; p&lt;0.05). Visual coloration values ranged from 14.46±0.23 in the 30 ppm astaxanthin group to 11.55±0.25 in the control. Retention coefficients ranged from 6.63 in the 30 ppm astaxanthin group to 1.79 in the 60 ppm shrimp by-products meal (p&lt;0.05). Tristimulus chromometer a values ranged from 0.87±0.47 in the control to 6.96±0.47 in the 60 ppm astaxanthin treatment, b values from 10.94±0.27 in the control to 12.90±0.27 in the 60 ppm red pepper meal treatment, and L values from 46.81±0.50 in the 60 ppm astaxanthin group to 54.57±0.26 in the control (p&lt;0.05).

Die wall lubrication is one of the most effective methods for producing high density compact P/M parts. Therefore a die wall lubrication system that can be applied to industrial compaction process was developed. The simple compact system has a precise intermittent spraying system and sensing device to monitor spraying status. Compaction trials showed improved results when applied to the P/M mass production process. ■特集:素形材
Progress in quasi-optical power combining (2017)

In order to increase the power available from solid-state sources, spatial combiners are being developed. Frequently the familiar waveguide or cavity combiners have serious disadvantages. In the past few years significant investigations have been carried out to develop planar arrays of solid-state oscillators or amplifiers in order to produce spatial combining. Some of these structures have used quasi- optical resonators for coupling the sources to provide feedback for frequency locking. Sources utilized have included Gunn, IMPATT, or resonant tunneling diodes, as well as three-terminal devices such as FETs or HEMTS, with the latter types being preferred because they offer higher efficiency, better control, and monolithic capability. This presentation will summarize progress to date.
Similarity Based Modeling for Turbine Exit Temperature Spread Monitoring on Gas Turbines (2013)

Failures in the gas path of a Gas Turbine will cause a deviation in the measured performance parameters. One of the most important parameters is the Turbine Exit Temperature (TET) and refers to the hot gas temperature at the exhaust of a Gas Turbine (GT). However, TET is not uniform at the turbine outlet and the temperature is therefore sometimes measured at several axial and radial positions. The TET has what can be considered a natural variation, an effect of operation in different ambient and operational conditions which influences the internal flow field. It can be informative on the health status of the GT by monitoring the TET variation during operation, as a number of failures or abnormal operation conditions will affect the TET distribution. A regular way of monitoring the TET is to use the average value from different sensor readings, or compare the highest deviating sensor to the average value of all sensors. However in order to detect anomalies as early as possible deviations from the healthy profile should be detected more finely across the section. In this paper, a data-driven similarity based algorithm called Auto Associative Kernel Regression is applied to the issue of monitoring the TET spread variation on an industrial gas turbine. A case study is supplied to show the practical usefulness of the algorithm to a field failure.
Differential Expression of MART-1, Tyrosinase, and SM5-1 in Primary and Metastatic Melanoma (2005)

The new monoclonal antibody SM5-1 has been shown to have significant advantages in immunohistochemistry of melanoma over currently used antibodies such as HMB-45 or anti-S100. In this study we compared the immunohistological staining pattern of SM5-1 with that of the more recently described antibodies A103 (anti-MART-1) and T311 (anti-Tyrosinase) in 344 paraffin-embedded melanoma specimens, consisting of 101 primary melanomas (77 SSM, 16 NM, 6 ALM, 2 LMM) and 243 melanoma metastases. The overall reactivity of SM5-1 for all the specimens was 92% (318/344) compared with 83% (285/344) for MART-1 and 71% (245/344) for Tyrosinase. Staining of melanoma metastases with SM5-1 was found in 91% (222/243), but only in 77% (187/243) with A103 and 63% (154/243) with T311, respectively. Staining with SM5-1 was more homogenous with 196 of 243 (80%) of metastatic lesions showing 50% or more positively stained cells within the lesions, whereas A103 and T311 did so in 141 of 243 (58%) or 117 of 243 (48%) of the lesions. With regard to staining intensity of SM5-1, 157 of 243 (64%) showed a strong or very strong staining intensity, whereas A103 and T311 did so in 85 of 243 (35%) or 70 of 243 (29%) of the lesions. Staining intensity and percentage positivity correlated well for SM5-1, because from the 58 very strong positive metastases 55 showed staining in more than 75% of the cells within a lesion. Importantly, 52 of 56 MART-1-negative metastases and 81 of 89 Tyrosinase-negative metastases were positive for SM5-1. Thirty-eight metastases (15.6%) were negative for both A103 and T311. Of those, 35 (92.1%) were positive for SM5-1, demonstrating the value of SM5-1 in identifying melanoma-associated antigen-negative lesions. We conclude that SM5-1 could be of value in immunohistochemistry of melanoma.
The Promise of Hox11+ Stem Cells of the Spleen for Treating Autoimmune Diseases (2008)

The spleen of human adults uniquely possesses a reservoir of multilineage adult stem cells that express the developmental transcription factor HOX11. In contrast to hematopoietic stem cells, HOX11+ stem cells hold potentially broader therapeutic applications because they are less lineage restricted. HOX11/TLX1 is part of a homeodomain gene family essential for organogenesis of the spleen and for contributions to development of hindbrain, cochlea, pancreas, salivary glands, among other organs and tissues. While HOX11/TLX1 displays widespread patterns of expression during embryogenesis, its expression was thought to cease after birth. Recent findings in human post-mortem tissue have shattered this dogma, finding that HOX11/TLX1 stem cells are uniquely and abundantly expressed throughout adulthood in the human spleen. While their role in humans is not yet understood, HOX11/TLX1 stem cells from the spleen of normal mice have been harvested to assist in both the treatment and cure at least two autoimmune diseases: type 1 diabetes, Sjogren's syndrome, and possibly their comorbid hearing loss. The splenic stem cells are infused, with an immune therapy, into diseased NOD mice, where they can home to the diseased organ, differentiate into the appropriate cell type, and assume normal functioning with the endogenous regeneration of the animal due to disease removal. This review covers HOX11/TLX1+ stem cells' success in an animal model and their potential for treating autoimmune diseases in organs that mirror their extensive expression patterns during embryogenesis.
