Decoupled Active and Reactive Power Control for Large-Scale Grid-Connected Photovoltaic Systems Using Cascaded Modular Multilevel Converters (2014)

Large-scale grid-connected photovoltaic (PV) systems significantly contribute to worldwide renewable energy growth and penetration, which has inspired the application of cascaded modular multilevel converters due to their unique features such as modular structures, enhanced energy harvesting capability, scalability and so on. However, power distribution and control in the cascaded PV system faces tough challenge on output voltage overmodulation when considering the varied and nonuniform solar energy on segmented PV arrays. This paper addresses this issue and proposes a decoupled active and reactive power control strategy to enhance system operation performance. The relationship between output voltage components of each module and power generation is analyzed with the help of a newly derived vector diagram which illustrates the proposed power distribution principle. On top of this, an effective control system including active and reactive components extraction, voltage distribution and synthesization, is developed to achieve independent active and reactive power distribution and mitigate the aforementioned issue. Finally, a 3-MW, 12-kV PV system with the proposed control strategy is modeled and simulated in MATLAB and PSIM cosimulation platform. A downscaled PV system including two cascaded 5-kW converters with proposed control strategy is also implemented in the laboratory. Simulation and experimental results are provided to demonstrate the effectiveness of the proposed control strategy for large-scale grid-connected cascaded PV systems.

Regulation of germ layer formation by pluripotency factors during embryogenesis (2013)

The classical pluripotency factors Oct4, Klf4, Sox2, and Nanog are required for the maintenance of pluripotency and self-renewal of embryonic stem (ES) cells and can reprogram terminally differentiated cells into a pluripotent state. Alteration in the levels of these factors in ES cells will cause differentiation into different lineages, suggesting that they are critical determinants of cell fates. These factors show dynamic expression patterns during embryogenesis, in particular in the pluripotent or multipotent cells of an early stage embryo, implying that they are involved in the cell fate decision during early embryonic development. Functions and the underlying molecular mechanisms have been extensively studied for these factors in ES cells under cultured conditions. However, this does not mean that the results also hold true for intact embryos. In the review, I have summarized and discussed the findings on the functions and the underlying mechanisms of the classical pluripotency factors during early embryogenesis, in particular during germ layer formation.
Flow Cytometric Bivariate Analysis of DNA and Cytokeratin in Colorectal Cancer (2002)

Different opinions about flow cytometric estimates of DNA aneuploidy and/or S-phase fraction (SPF) as supplementary prognostic markers in colorectal cancer are to some degree associated with methodology. Using univariate DNA analysis, we have previously investigated the DNA ploidy in colorectal cancer, its heterogeneity within and between tumors and its relation to survival. To improve detection of DNA aneuploid subpopulations and particularly estimation of their SPF's we investigated a method for bivariate DNA/cytokeratin analysis on fine-needle aspirates of 728 frozen biopsies from 157 colorectal tumors. Unfixed aspirates were stained with propidium iodide and FITC-conjugated anti-cytokeratin antibody in a saponin-buffer. A significant association between SPF and debris was observed. There were no substantial difference in DNA ploidy patterns between univariate and bivariate measurements (concordance was 92-95%). No new DNA aneuploid subpopulations were detected in cytokeratin-gated compared to ungated or univariate histograms. Debris-adjusted SPF's of cytokeratin-gated histograms were significantly higher than of ungated histograms, also for subpopulations with DI>1.4 (p<0.0001). There was no significant association between SPF and survival.
Gross Cystic Disease Fluid Protein-15(GCDFP-15)/Prolactin-Inducible Protein (PIP) as Functional Salivary Biomarker for Primary Sjögren’s Syndrome (2013)

In this study by different complementary-omic techniques we confirmed the potential role of GCDFP-15/PIP as a novel biomarker for pSS. This finding might also be functionally important as GCDFP-15/PIP has previously been shown to bind to Aquaporin 5 (AQP5), a salivary gland water channel, critical to saliva formation that is known to be downregulated in pSS. It is likely that exploring the GCDFP-15/PIP/AQP5 axis will help better understand the mechanism of salivary gland dysfunction in pSS.
Development of Hot Dry Rock Geothermal Energy at Hijiori Test Site. (1996)

Technologies to develop the Hot Dry Rock (HDR) geothermal energy was reviewed. Since 1985, the New Energy and Industrial Technology Development Organization (NEDO) has promoted HDR project at Hijiori with the technical support from National Institute for Resources and Environment (NIRE) under New Sunshine Program. The objective of this project is to develop and confirm technologies which are required for the development of HDR. In 1991, a heat extraction test was successfully conducted with a 1, 800 m deep reservoir for three month using one injection well (SKG-2) and three production wells (HDR-1, HDR-2 and HDR-3). Water recovery during the test was about 80 % and the thermal output of the produced water and steam was about 8 MW. Deep reservoir with the depth of 2, 200 m has been developed for future heat extraction test for about two years.
FTY 720 EFFICIENTLY PROLONGS ALLOGRAFT SURVIVAL BY SUPPRESSING T CELL-DEPENDENT AND T CELL-INDEPENDENT IMMUNITY (1999)

205 The novel immunosuppressant FTY 720 prolongs allograft survival with remarkable potency. This is documented for allografted rat skin (0.1-10 mg/kg/d), rat heart (0.1-10 mg/kg/d), and (in combination with CsA) for dog kidney (0.1-5 mg/kg/d) and monkey kidney (0.1-1 mg/kg/d). Unlike CsA and FK506, FTY 720 does not inhibit T and B cell function in vitro irrespective of the mode of cell activation. FTY 720 does not affect proliferation and production of TH1 and TH2 cytokines by human T cells or the production of antibody by human B cells. Moreover, FTY 720 does not synergize with CsA, FK506, or rapamycin in vitro to suppress human T cell function despite the remarkable synergy of FTY 720 and CsA observed in transplantation models in vivo. This suggests a completely new mechanism of action for FTY 720 that is different from that of CsA and FK506. In vivo, FTY 720 inhibits with remarkable potency the CD4 T cell-dependent immune responses to DNP-KLH in mice (IC50 0.01 mg/kg) and to SRBC in rats (IC50 0.1 mg/kg), and suppresses the T cell-independent antibody formation to TNP-LPS in rats (IC50 1mg/kg). Moreover, FTY 720 suppresses the generation of cytotoxic CD8 T lymphocytes in the spleen. The immunosuppression by FTY 720 relates to an altered migration of antigen-specific lymphocytes between lymphoid tissues rather then a direct inhibition of cellular function.
Universal trellis coded quantization (1999)

A new form of trellis coded quantization based on uniform quantization thresholds and "on-the-fly" quantizer training is presented. The universal trellis coded quantization (UTCQ) technique requires neither stored codebooks nor a computationally intense codebook design algorithm. Its performance is comparable with that of fully optimized entropy-constrained trellis coded quantization (ECTCQ) for most encoding rates. The codebook and trellis geometry of UTCQ are symmetric with respect to the trellis superset. This allows sources with a symmetric probability density to be encoded with a single variable-rate code. Rate allocation and quantizer modeling procedures are given for UTCQ which allow access to continuous quantization rates. An image coding application based on adaptive wavelet coefficient subblock classification, arithmetic coding, and UTCQ is presented. The excellent performance of this coder demonstrates the efficacy of UTCQ. We also present a simple scheme to improve the perceptual performance of UTCQ for certain imagery at low bit rates. This scheme has the added advantage of being applied during image decoding, without the need to reencode the original image.
Synthesis of Rhodamine 6G-Based Compounds for the ATRP Synthesis of Fluorescently Labeled Biocompatible Polymers (2011)

Facile derivatization of rhodamine 6G in the 2' position by direct reaction with secondary amines is reported. If the secondary amine contains a hydroxy group, the hydroxyl-functional intermediate can be readily esterified to give either fluorescent initiators for atom transfer radical polymerization (ATRP) or a fluorescent methacrylic comonomer. In contrast to rhodamine dyes functionalized using primary amines, which are only fluorescent at low pH, these compounds are highly fluorescent at physiological pH. These new compounds were subsequently used to prepare a range of fluorescently labeled biocompatible polymers based on the biomimetic monomer, 2-(methacryloyloxy)ethyl phosphorylcholine (MPC), for biomedical studies.
Ecological Validation of Machine Learning Models for Spatiotemporal Gait Analysis in Free-living Environments Using Instrumented Insoles (2022)

Continuous gait monitoring may aid the early diagnosis of neurological and musculoskeletal conditions and help validate the effectiveness of new treatments. However, consumer-grade activity trackers can only capture summary gait metrics, whereas most of the research-grade devices capable of estimating fine-grained gait parameters are too cumbersome for extended-time use in real-life environments. Instrumented footwear may offer a promising alternative tool owing to their good accuracy and relatively small form factor, but their ability to detect stride-by-stride spatial gait parameters in free-living conditions has not been well explored to date. This work describes machine learning (ML) inference models for an insole system capable of accurately estimating stride time (ST), length (SL), and velocity (SV) in real-life environments. Functional validity was assessed through unstructured tests including straight-line walking, curve walking, and turns. Ecological validity was examined in free-living conditions. The ML models demonstrated better accuracy than conventional data processing methods (mean absolute errors in unstructured conditions were 3.55% for SL and 3.59% for SV). Real-life gait parameters estimated with the ML models showed stronger associations with a standardized walking test compared with the same parameters obtained with conventional methods. These results indicate proof-of-concept feasibility of using instrumented insoles and ML inference models for free-living spatiotemporal gait analysis.
A Content Integrity Service For Long-Term Digital Archives (2006)

integrity, archiving, storage, security, authentication We present a content integrity service for long-lived digital documents, especially for objects stored in long-term digital archives. The goal of the service is to demonstrate that information in the archive is authentic and has not been unintentionally or maliciously altered, even after its bit representation in the archive has undergone one or more transformations. We describe our design for an efficient, secure service that achieves this, and our implementation of the first prototype of such a service that we built for HP&amp;apos;s Digital Media Platform. Our solution relies on one-way hashing and digital time-stamping procedures. Our service applies not only to transformations to archival content such as format changes, but also to the introduction of new cryptographic primitives, such as new one-way hash functions. This feature is absolutely necessary in the design of an integrity-preserving system that is meant to endure for decades.
SURFACE MINE POOL RECLAMATION WITH DIRECT ASH PLACEMENT (2002)

A demonstration project has been put in place to evaluate the effect of ash placement in an acid mine pool. The surface mine pool, initially 510 million liters, is a remnant of pre-WWII mining of the Mammoth vein in the Eastern Middle anthracite field of Pennsylvania. Fly and bottom ash are placed at the face of two ash platforms in 32 Mg loads and later pushed into the mine pool with bulldozers. Natural compaction of the ash provides a load-bearing capacity of greater than 69 MPa, which is sufficient to permit trucks and bulldozers on the ash platforms. Once subaqueous deposition has been completed, the FBC ash will be covered with four feet of soil and seeded. The pH value of the mine pool increased from 3.6 to 12.1 following ash placement. Calcite now precipitates from the top few feet of the water surface. The alkaline water has caused the precipitation of metals typically associated with acid mine drainage. Water samples collected from two test borings in the ash platform show a chemical signature very close to that of the surface mine pool. Despite the dramatic and homogeneous change in surface mine pool chemistry, no effect has been observed in any of the monitoring wells or at the outflow point of the basin.
Computing nearest neighbors for moving points and applications to clustering (1999)

<title>Electro-optical-based machine vision for weed identification</title> (1999)

This work evaluates real-time techniques for a novel concept of identifying weeds, location and extraction of outline features. THE proposed techniques are conducted by electro- optical methods and perform with the speed of light. The optical system is compact, easy to align and uses a small number of inexpensive components. Generating the 'right' filter for a pattern recognition problem is presented as an optimization process for which the filter performance is the function to be maximized. The genetic algorithm is introduce as a search procedure that uses a biologically motivated random choice as a tool to guide a highly exploitative search through the filter space for nonlinear correlation. The features of the genetic algorithm are ideal for a highly efficient and fast learning process. Computer simulations demonstrate very efficient pattern recognition and excellent discrimination.
Environment, political economies and livelihood change (2015)

Between the national and household factors, community or “meso-level” changes in political economy and livelihoods in southwestern Bangladesh illustrate that in order to understand the impacts on people and nations of climate change-related environmental changes – changes that are expected to include rising sea level, saline inundation, and increased likelihood and intensity of cyclones in Bangladesh – we need to understand the dynamics of the built and natural environment and the political economies these sustain. Meso-level political economies affect the sources of income and livelihood available in distressed environmental conditions, and therefore influence how well the people in them can adapt to changing environmental conditions. In this study we have seen the underlying political economies whose dynamics, and not slow onset environmental changes or disastrous environmental events, are pushing Bangladeshis to incorporate migration strategies into their livelihood strategies.
Effective Modulating Brassinosteroids Signal to Study Their Specific Regulation of Reproductive Development and Enhance Yield (2019)

Brassinosteroid (BR) is a family of bioactive steroid hormones that plays vital roles in plant growth and development. The BR-mediated regulation of plant growth and architecture has been well studied. However, relatively few studies have investigated the BR-related regulation of reproductive development because of the difficulties in excluding non-specific regulation and secondary responses from severe vegetative phenotypes and poor nutritional status. Furthermore, differentially regulating the BR signal in vegetative and reproductive organs is problematic. Thus, establishing a method for modulating the BR signal only in reproductive organs or during reproductive developmental stages will be beneficial. Additionally, the utility of BR applications for crop production is limited because of deleterious side-effects, including the associated decrease in the planting density and lodging resistance. Moreover, enhancing the BR signal may lead to feedback inhibition. In this study, we developed a transformation system for modulating the BR signal differentially during reproductive and vegetative developmental stages. This system involves transformations with different combinations of a reproductive tissue-specific promoter, coding sequences that increase or decrease the BR signal, and various genotypic backgrounds with enhanced or decreased BR signals. The enhanced BR signal generated in transformants was targeted to reproductive organs without affecting vegetative organs. This system may be useful for studying the BR-specific regulation of plant reproductive development and shows promise for optimizing seed yield.
Inhibition study on insulin fibrillation and cytotoxicity by paclitaxel (2014)

Alzheimer, a neurodegenerative disease, and a large variety of pathologic conditions are associated with a form of protein aggregation known as amyloid fibrils. Since fibrils and prefibrillar intermediates are cytotoxic, numerous attempts have been made to inhibit fibrillation process as a therapeutic strategy. Peptides, surfactants and aromatic small molecules have been used as fibrillation inhibitors. Here we studied the effects of paclitaxel, a polyphenol with a high tendency for interaction with proteins, on fibrillation of insulin as a model protein. The effects of paclitaxel on insulin fibrillation were determined by Thioflavin T fluorescence, Congo red absorbance, circular dichroism and atomic force microscopy. These studies indicated that paclitaxel considerably hindered nucleation, and therefore, fibrillation of insulin in a dose-dependant manner. The isothermal titration calorimetry studies showed that the interaction between paclitaxel and insulin was spontaneous. In addition, the van der Waal's interactions and hydrogen bonds were prominent forces contributing to this interaction. Computational results using molecular dynamic simulations and docking studies revealed that paclitaxel diminished the polarity of insulin dimer and electrostatic interactions by increasing the hydrophobicity of its dimer state. Furthermore, paclitaxel reduced disrupting effects of insulin fibrils on PC12 cell's neurite outgrowth and complexity, and enhanced their survival.
Auditing is key (2009)

Auditing is a key element to ensure that an effective electrical safety program exists in your facility. It is recommended that internal audits be performed at least once each year and that external audits be performed not to exceed once every three years. Auditing provides the means to understand performance versus established standards and identify areas for continued improvement. To have an effective electrical safety program, an auditing process must be an integral element of the electrical safety program. An effective audit program helps to ensure that the electrical safety management systems are maintained and sustainable. A set of audit criteria and protocol provides the framework or basis for the audit program. Using protocols is beneficial to ensure consistency of the audits. To be truly effective, an audit program must be designed to be sustainable, both in terms of management commitment to the process and to the ongoing development of knowledgeable and capable auditors. A management process that addresses the content and scope of the audits, standards and regulations that apply to the facilities, use of audit protocols, the frequency of audits, and training of auditors is integral to an effective and sustainable auditing program. A sustainable auditing program ensures that the electrical safety procedures, recordkeeping, and operating discipline are continuously monitored and improved upon, and in the end, electrical-related incidents and injuries are reduced.
Clinical Experience with a System of Direct Componeer（Coltene/Whaledent, Switzerland） Composite Veneers.Work Difficulties and Ways of Overcoming Them (2014)

A system of finished Componeer composite veneers is a unique and having no analogy in the world elaboration of the Swisscompany Coltene/Whaledent, an outcome of almost halfa century experience of the company working in a field of composite materials.It combines the best features of direct and indirect restoration methods. The system is fulfilled of nanocomposite Synergy D6 that hashigh mechanical strength, convenience for workable consistency, color stability and a system of halftone shades, which facilitates colormatching. All this allows achieving excellent aesthetic results in minimal time. Application of an original standard scale givespossibility effectively assess optical properties of dental hard tissues and develop an implementation strategy of restoration before workstarted. Formation of Componeer form, polymerization and polishing at factory allow a practitioner fully utilize effect of＂fluorescence＂ inherent to the material. All this allows us to position the Componeer system as a serious alternative to non-directmethods of restoration with the possibility of both high aesthetic and cosmetic reconstruction reliability.
Mating Behavior of Bollworm Moths1,2,3,4 (1969)

The bollworm moth, Heliothis zea (Boddie) (Lepidoptera: Noctuidae), vibrates its wings during courtship, and the male wipes the scales of his claspers on a supporting surface between periods of vibration. Receptive females extend the terminal abdominal segments and vibrate their wings. Then the receptive female, whose terminal abdominal segments are extended and whose wings are vibrating, is approached from behind by the male who taps the ovipositor of the female with his antennae, crawls to a position at the side of and about 2 cm from and parallel to her, and snaps his claspers around her genitalia to complete the copulatory connection. Mated pairs remain in copula from ¾ to 1½ hr.
Crawler-Friendly Web Servers (2000)

In this paper we study how to make web servers (e.g., Apache) more crawler friendly. Current web servers offer the same interface to crawlers and regular web surfers, even though crawlers and surfers have very different performance requirements. We evaluate simple and easy-to-incorporate modifications to web servers so that there are significant bandwidth savings. Specifically, we propose that web servers export meta-data archives decribing their content.
Large aperture laser beam attenuator using electro-optic gratings (2007)

This paper provides research progress in the development of fast electro-optic gratings for high energy laser beam attenuations. The electro-optic phase grating is formed by the phase separation of small liquid crystals droplets from a polymerizing organic matrix using holographic interference technique. The formed grating separates the incident laser beam into two output beams: the transmitted and diffracted beam, whose intensities can be electrically adjusted through electro-optic effect. The fast electro-optic gratings have a very fast electro-optic response time of 50 &mgr;s is with diffraction efficiency above 99%.
