Reaction of cycloheptatriene with ruthenium carbonyl: X-ray crystallographic determination of the molecular structure of Ru3(CO)6(C7H7)(C7H9) (1973)

Cycloheptatriene reacts with dodecacarbonyl-triruthenium to give inter alia a fluxional complex Ru3(CO)6(C7H7)(C7H9)(I), an X-ray diffraction study of which reveals that the C7H7 ring bridges two of the ruthenium atoms whereas the C7H9 ring is attached to the remaining metal atom as a cycloheptadienyl ligand.

Deficiency or Inhibition of CD73 Protects in Mild Kidney Ischemia-Reperfusion Injury (2010)

Deficiency or inhibition of CD73 protects in kidney IRI, and CD39-mediated protection does not seem to be dependent on adenosine generation. These findings suggest that AMP may play a direct protective role in kidney IRI, which could be used in therapeutic development and organ preservation. Investigating the mechanisms by which AMP mediates protection may lead to new targets for research in kidney IRI.
Initial results of cardiac imaging at 7 tesla (2008)

This work reports preliminary results from the first human cardiac imaging at 7 Tesla (T). Images were acquired using an eight-channel transmission line (TEM) array together with local B(1) shimming. The TEM array consisted of anterior and posterior plates closely positioned to the subjects' thorax. The currents in the independent elements of these arrays were phased to promote constructive interference of the complex, short wavelength radio frequency field over the entire heart. Anatomic and functional images were acquired within a single breath hold to reduce respiratory motion artifacts while a vector cardiogram (VCG) was used to mitigate cardiac motion artifacts and gating. SAR exposure was modeled, monitored, and was limited to FDA guidelines for the human torso in subject studies. Preliminary results including short-axis and four-chamber VCG-retrogated FLASH cines, as well as, short-axis TSE images demonstrate the feasibility of safe and accurate human cardiac imaging at 7T.
Reduction of porosity in aluminum alloy die castings by compression load (2006)

The porosity in die castings has an influence on their mechanical properties or air leakage efficiency. To reduce the porosity, we examined compression tests of disk shaped ADC12 aluminum alloy die castings at room temperature. Also, finite element analyses are carried out corresponding to the compression tests. The porosity of the die castings decreases when the compression strain of the specimen increases, particularly in the middle area of the specimen where many defects exist. Thus, this type of compression load is significantly efficient in reducing the variation in the quality of die castings. However, it is necessary to investigate the condition of compression strain that prevents the initiation of cracks during the compression loading.
Nonlinear Pulse Compression to Sub-40 fs at $4.5~\mu$ J Pulse Energy by Multi-Pass-Cell Spectral Broadening (2017)

We report on the pulse compression of an 18.5 MHz repetition rate pulse train from 230 fs to sub-40 fs by nonlinear spectral broadening in a multi-pass cell and subsequent chirp removal. The compressed pulse energy is <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$4.5~\mu \text{J}$ </tex-math></inline-formula> , which corresponds to 84 W of average power, with a compression efficiency of 88%. This recently introduced compression scheme is suitable for a large pulse energy range and for high average power. In this paper, we show that it can achieve three times shorter pulses than previously demonstrated.
Transformative role of photovoltaics in phasing out alternating current based grid by local DC power networks for sustainable global economic growth (2016)

For sustainable global economic growth, eradication of global energy poverty and addressing climate challenges, free fuel based solar and wind energy sources are the only viable solution for electricity generation. Due to inherent advantages, photovoltaics has emerged as the major source of electrical power. Local generation of direct current (DC) power by PV and the use of batteries for storing DC electrical power have the potential of transforming global electricity infrastructure to address the problems faced by alternating current (AC) based centralized power generation and long haul transmission and distribution.
ParaDime: A Framework for Parametric Dimensionality Reduction (2023)

ParaDime is a framework for parametric dimensionality reduction (DR). In parametric DR, neural networks are trained to embed high-dimensional data items in a low-dimensional space while minimizing an objective function. ParaDime builds on the idea that the objective functions of several modern DR techniques result from transformed inter-item relationships. It provides a common interface for specifying these relations and transformations and for defining how they are used within the losses that govern the training process. Through this interface, ParaDime unifies parametric versions of DR techniques such as metric MDS, t-SNE, and UMAP. It allows users to fully customize all aspects of the DR process. We show how this ease of customization makes ParaDime suitable for experimenting with interesting techniques such as hybrid classification/embedding models and supervised DR. This way, ParaDime opens up new possibilities for visualizing high-dimensional data.
Instantaneous Corrosion Rate Measurement with Small-Amplitude Potential Intermodulation Techniques (1996)

With the intermodulation technique, a potential distortion using two sine waves is applied to a corrosion system. The alternating current (AC) response consists of amplitudes measured at different frequencies. Simple relations are derived from the current-vs-potential relation for a corroding process under activation control, from which the corrosion rate and Tafel parameters can be calculated. These are valid when the amplitude of the applied potential distortion is sufficiently small. With the intermodulation technique, the corrosion rate and Tafel parameters can be obtained within one measurement, which makes this technique an ideal candidate for application as a corrosion monitoring tool. Results obtained with this technique were shown to be in agreement with other electrochemical methods for corrosion rate measurement, such as Tafel extrapolation, linear polarization resistance (LPR), and electrochemical impedance spectroscopy (EIS).
Validation of lung nodule detection a year before diagnosis in NLST dataset based on a deep learning system (2021)

<b>Background:</b> A deep learning system for lung nodule detection from low dose CT scans was trained on a public database. This study aims to evaluate its performance on an independent screening dataset and specifically its ability to detect malignant lesions one year prior to diagnosis. <b>Methods:</b> The algorithm was solely trained on the LIDC-IDRI dataset containing 888 CT scans where radiologists characterized nodules exclusively based on radiological criteria. We tested the framework on 1179&nbsp;patients from the NLST study with biopsy-confirmed nodule malignancy, for which 2 CT scans are available one year apart. Among them, 177 were diagnosed with cancer the last year. For those cases, the algorithm was applied both on the image at diagnosis and on the image one year before. Thus, the NLST test dataset is larger than the LIDC training set and corresponds to distinct populations. <b>Results:</b> The system detected 75% of all annotated nodules from 1179 patients, including 68% of the 2352 benign nodules and resulted in 12 extra candidate nodules per scan in average. Among the 177 malignant nodules, the system detected 172 regions of interest within 3 cm of their ground truth location corresponding to a sensitivity of 97%. The 5 undetected lesions were located next to the mediastinum. On the corresponding image one year prior to diagnosis, 20 nodules were not visible, and the algorithm detected 152 malignant nodules among the 157 visible nodules. <b>Conclusion:</b> The algorithm only trained on the LIDC-IDRI dataset without any biopsy characterization of lung nodules showed good performance at detecting malignant biopsy-confirmed lesions even one year prior to their detection by radiologists.

Archaeal Glycerolipids Are Recognized by C-Type Lectin Receptor Mincle (2023)

Recently, various metabolites derived from host microbes have been reported to modulate the immune system, with potential involvement in health or diseases. Archaea, prokaryotic organisms, are present in the human body, but their connection with the host is largely unknown when compared to other microorganisms such as bacteria. This study focused on unique glycerolipids from symbiotic methanogenic archaea and evaluated their activities toward an innate immune receptor. The results revealed that archaeal lipids were recognized by the C-type lectin receptor Mincle and induced immune responses. A concurrent structure-activity relationship study identified the key structural features of archaeal lipids required for recognition by Mincle. Subsequent gene expression profiling suggested qualitative differences between the symbiotic archaeal lipid and the pathogenic bacteria-derived lipid. These findings have broad implications for understanding the function of symbiotic archaea in host health and diseases.

Phase II trial of pirfenidone in children and young adults with neurofibromatosis type 1 and progressive plexiform neurofibromas (2014)

Pirfenidone was well tolerated, but did not demonstrate activity as defined in this trial and does not warrant further evaluation in children with NF1 and progressive PN.
The ROD Crate DAQ of the ATLAS data acquisition system (2005)

In the ATLAS experiment at the LHC, the ROD Crate DAQ provides a complete framework to implement data acquisition functionality at the boundary between the detector specific electronics and the common part of the data acquisition system. Based on a plugin mechanism, it allows selecting and using common services (like data output and data monitoring channels) and developing simple libraries to control, monitor, acquire and/or emulate detector specific electronics. Providing also event building functionality, the ROD Crate DAQ is intended to be the main data acquisition tool for the first phase of detector commissioning. This paper presents the design, functionality and performance of the ROD Crate DAQ and its usage in the ATLAS DAQ and during detector tests
Max-Affine Spline Insights into Deep Generative Networks (2020)

We connect a large class of Generative Deep Networks (GDNs) with spline operators in order to derive their properties, limitations, and new opportunities. By characterizing the latent space partition, dimension and angularity of the generated manifold, we relate the manifold dimension and approximation error to the sample size. The manifold-per-region affine subspace defines a local coordinate basis; we provide necessary and sufficient conditions relating those basis vectors with disentanglement. We also derive the output probability density mapped onto the generated manifold in terms of the latent space density, which enables the computation of key statistics such as its Shannon entropy. This finding also enables the computation of the GDN likelihood, which provides a new mechanism for model comparison as well as providing a quality measure for (generated) samples under the learned distribution. We demonstrate how low entropy and/or multimodal distributions are not naturally modeled by DGNs and are a cause of training instabilities.
Separating Faradaic and Non-Faradaic Charge Storage Contributions in Activated Carbon Electrochemical Capacitors Using Electrochemical Methods (2015)

Development of an electrochemical method for separating the contributions made by faradaic and non-faradaic processes to the total specific capacitance of an electrochemical capacitor electrode is reported. The method is based on step potential electrochemical spectroscopy (SPECS), and its application is demonstrated on activated carbon electrodes in aqueous media. The method involves applying a sequence of small potential steps (±25 mV) across the electrochemical window of the electrode material, with sufficient rest time between steps to allow for current equilibration. Modelling of the resultant i-t data using combined resistive, capacitive, diffusional and residual current terms allows for separation of the faradaic and non-faradaic terms. The behavior of these contributions across the electrode potential window is reported and discussed in comparison with conventional methods of electrochemical analysis, such as cyclic voltammetry.
Inhibitory effects of rosmarinic acid extracts on porcine pancreatic amylase in vitro. (2004)

Porcine pancreatic alpha-amylase (PPA) was allowed to react with herbal extracts containing rosmarinic acid (RA) and purified RA. The derivatized enzyme-phytochemical mixtures obtained were characterized for residual amylase activity. These in vitro experiments showed that the amylase activity was inhibited in the presence of these phytochemicals. The extent of amylase inhibition correlated with increased concentration of RA. RA-containing oregano extracts yielded higher than expected amylase inhibition than similar amount of purified RA, suggesting that other phenolic compounds or phenolic synergies may contribute to additional amylase inhibitory activity. The significance of food-grade, plant-based amylase inhibitors for modulation of diabetes mellitus and other oxidation-linked diseases is hypothesized and discussed.
Photoluminescence Efficiency and Size Distribution of Self Assembled Ge Dots on Porous TiO<SUB>2</SUB> (2011)

For Ge nanodots approximately 20 nm in diameter grown by annealing a thin amorphous Ge layer deposited by molecular beam epitaxy on a mesoporous TiO2 layer on Si(001), photoluminescence (PL) was observed as a wide near-infrared band near 800 meV. Using a tight binding theoretical model, the energy-dependent PL spectrum was transformed into a dependence on dot size. The average dot size determined the peak energy of the PL band and its shape depended on the size distribution, including bandgap enlargement due to quantum confinement. Combining the dot sample PL with an established dependence of emission efficiency on dot diameter, it was possible to derive a dot size distribution and compare it with results obtained independently from atomic force microscopy.
A novel dynamometer system for testing high power variable frequency drives (2009)

In this paper is proposed a novel dynamometer system for testing high power variable frequency drives (VFD). This system, which is built and fully functional, has no movable parts. It is comprised of a 1.7MW active front end drive, a reconfigurable system of inductors and the drive under test. Main advantages of this dynamometer system are flexibility, high efficiency, low maintenance, small footprint and environmental friendly. The flexibility of the system allows for testing drives at different power, voltage and frequency levels. Since the power is circulated within the system, the power loss is minimal and the energy savings and environmental benefits are considerable, especially when testing high power drives. By using a motor-less system the audible noise levels are reduced and the maintenance work virtually eliminated. The system is remotely controlled from a computer controlled interface through Profibus. Results presented in this paper show that the dynamometer system not only performs very well in testing the drives under their full power capability, but also does not interfere with the normal operation of the factory equipment fed from the same distribution transformer.
Research on typical topologies of a tubular horizontal-gap passive magnetic levitation vibration isolator (2017)

Magnetic levitation vibration isolators have attracted more and more attention in the field of high-precision measuring and machining equipment. In this paper, we describe a tubular horizontal-gap passive magnetic levitation vibration isolator. Four typical topologies of the tubular horizontal-gap passive magnetic levitation vibration isolator are proposed. The analytical expression of magnetic force is derived. The relationship between levitation force, force density, force ripple and major structural parameters are analysed by finite element method, which is conductive to the design and optimization of the tubular horizontal-gap passive magnetic levitation vibration isolator. The force characteristics of different topologies of the tubular horizontal-gap passive magnetic levitation vibration isolator are compared and evaluated from the aspect of force density, force ripple and manufacturability. In comparison with conventional passive magnetic levitation vibration isolators, the proposed tubular horizontal-gap passive magnetic levitation vibration isolator shows advantage in higher force density.
Cost/Performance in Modern Data Stores: How Data Caching Systems Succeed (2019)

Summary form only given, as follows. The complete presentation was not made available for publication as part of the conference proceedings. Data in traditional "caching" data systems resides on secondary storage, and is read into main memory only when operated on. This limits system performance. Main memory data stores with data always in main memory are much faster. But this performance comes at a cost. In this paper, we analyze the costs of both in-memory operations and secondary storage operations where data is not "in cache". We study the performance impact of cache misses on caching system performance. The analysis considers both execution and storage costs. Based on our analysis, we derive cost/performance results for a data caching system [Deuteronomy and its Bw-tree] and a main memory system [MassTree] to understand where each demonstrates the best cost per operation, what is driving the cost differences, and the scale of the differences. This analysis (1) provides insight into why data caching systems continue to dominate the market; (2) points to higher performance that does not rely on simply increasing main memory cache size; and (3) suggests a path to lower costs and hence better cost/performance.
994. Gene Knockdown in Mice by Using Lentiviral Vectors Expressing Small Interfering RNA (2004)

Top of pageAbstract
Many approaches have been described recently for generating loss-of-function phenotypes in eukaryotic systems using RNAi. Use of RNAi by means of long dsRNAs (>50bp) is limited in mammalian cells due to the induction of a nonspecific inhibitory response resulting from the interferon pathway. This limitation was overcome by the finding that small interfering RNAs (siRNAs) can specifically silence genes in mammalian cells without activating the nonspecific interferon pathway. We have designed lentiviral vectors expressing siRNAs to knock down the expression of specific genes. We have previously shown that a lentiviral vector capable of expressing siRNA specific for GFP (siGFP) was able to silence GFP expression in TgGFP mice upon transduction of fertilized mouse embryos. We have found that transgenesis of mouse embryos can be achieved both by zona pellucida removal prior to transduction and by microinjection of lentivirus particles under the intact zona layer. Efficiency of transgenesis was high using both methods, up to 80% and 100% respectively. However, survival of the treated embryos was low in the case of zona removal techniques (10-20%), compared to 40-60% for microinjection. We are currently using transgenesis by lentiviral vectors expressing small interfering RNAs to generate knockdown mice to study functional genomics.
