Control Strategies for Power Electronic Interfaces in Unbalanced Diesel Hybrid Mini-Grids with Renewable Sources and Storage (2013)

Traditionally, remote communities worldwide consist of autonomous power systems (mini-grids) supplied almost exclusively by diesel-engine generator sets (gensets) at relatively high costs. Integration of renewable energy sources (RESs), such as, photovoltaic (PV) and wind, can substantially reduce the cost of electricity generation and emissions in these remote communities. However, the highly variable load profile typical of mini-grids and the fluctuating characteristics of the RESs, cause frequent operation of the diesel genset at low loading condition, at low efficiency points and subject to carbon build up, which can significantly affect the maintenance costs and even the life time of the genset. Another important issue that is frequently overlooked in small (< 100 kVA) mini-grids, which usually present a low number of loads thus reducing the averaging effect, is load unbalance. Diesel gensets supplying unbalanced loads experience overheating in the synchronous generator and vibration in the shaft. For efficient operation, the genset should be operated near its full capacity and also in balanced mode.\nIn order to address the above mentioned issues, a fast and reliable multi-mode battery energy storage system (BESS) employing voltage source inverter (VSI), is proposed in this thesis. In the genset support mode, as a basic feature, it can provide minimum loading for the genset and supplement it under peak load conditions. In addition, it can also provide load balancing and reactive power compensation for the mini-grid system. Therefore, the genset operates in balanced condition and within its ideal power range. In cases when the power demand from the genset is low, due to high supply of RESs and/or low load consumption, the genset can be shut-down and the BESS forms the grid, regulating voltage and frequency of the mini-grid system in the grid forming mode. Besides, the logic for defining the operating mode of the BESS and for achieving smooth transitions between modes are also presented in this thesis.\nThe conventional approach for the control of three-phase VSI with unbalanced loads uses three-phase vector (dq) control and symmetrical components calculator which usually results in slow dynamic responses. Besides, the common power (P) vs. frequency (f) droop characteristic of the genset results in the mini-grid operating with variable frequency what further complicates the design of the controller for the VSI. Therefore, a new frequency adaptive per-phase dq-control scheme for three-wire and four-wire three-phase VSI based on the concept of fictive axis emulation is presented. It enables the control of current/voltage of each phase separately to achieve better dynamic performance in the variable frequency diesel hybrid mini-grid system. The effectiveness of the proposed techniques is demonstrated by means of simulation and experimental results.
Insect Species Richness: Hispine Bettles of Heliconia Latispatha (1977)

Lowland Costa Rican populations of Heliconia latispatha (Zingiberales) are attacked by six species of rolled leaf hispine beetles (Chrysomelidae). Each species feeds upon a specific plant part in both larval and adult stages: either the inflorescence, the edge of the rolled leaf, or the blade of the rolled leaf away from the edge. Lowlands in the Pacific North have a long dry season, and H. latispatha grows only ° 6 mo of the year and supports from zero to three hispine species. The Pacific Southern dry season is shorter, and H. latispatha grows ° 10 mo and supports four hispine species. The Caribbean lowlands have sufficient rain for H. latispatha to grow year round, and four rolled leaf hispine species are supported. Heliconia latispatha may be saturated with four species of rolled leaf Hispinae in the Caribbean lowlands and Pacific South. Between these two regions, the species associated with H. latispatha change, the pool of species with the potential to attack H. latispatha increases to five, and the total number of species attacking congeners of H. latispatha increases from six to eight.
The Phase Relationship and Denitrification during the Sintering Process of TiN&ndash;Ni Mixed Powder Compacts (1980)

In order to investigate the phase relationship during the sintering process of TiN–Ni mixed powder compacts, the nickel-rich portion of the vertical section between nickel-solid solution and titanium nitride was studied by using both sintered and arc-melted alloy specimens prepared from Ni and TiN, where a quasi-binary eutectic was found between a nickel-solid solution and stoichiometric TiN in the vertical plane. The eutectic composition was determined to be about 10 wt% Ti and 1.6 wt% N, and the melting point of the eutectic was found to be 1626±4 K. The maximum solubilities of Ti and N in the nickel-solid solution and the nickel solubility in the TiN phase at 1626 K were 4.84 wt% Ti, 0.06 wt% N and 0.31 wt% Ni, respectively.The structure of a quasi-binary eutectic between nickel-solid solution and TiN showed a complex stripe-like structure.It was found that nitrogen gas liberated upon formation of nickel-solid solution, but not from the liquid phase during the sintering process of TiN–Ni mixed powder compacts. Judging from the sintered densities, the liquid phase sintering of the TiN–Ni mixed powder compacts may be disturbed by liberated nitrogen gas which increases from about 1073 K to the eutectic temperature.

Improved thermal stability of ferromagnetic tunnel junctions with a CoFe/CoFeO/sub X/CoFe pinned layer (2003)

Annealing temperature dependence of the tunnel magnetoresistance (TMR) ratio for magnetic tunnel junctions with CoFeO/sub x/ inserted in the pinned layer was investigated. A junction with a CoFe/CoFeO/sub x//CoFe pinned layer exhibited TMR ratios of 46.5% and 42.5% after annealing at 350/spl deg/C and 375/spl deg/C, respectively. The reason for the improvement of the thermal stability is related to oxygen diffusion from the CoFeO/sub x/ layer, and there is a possibility that CoFeO/sub x/ plays the role of a Mn (in MnIr exchange layer) diffusion barrier.
Multicenter clinical trials of monoclonal antibody B72.3-GYK-DTPA 111In (111In-CYT-103; OncoScint CR103) in patients with colorectal carcinoma. (1992)

The results of this clinical trial involving 23 sites indicated that 111In-CYT-103 immunoscintigraphy identified 70% of all patients with surgically confirmed disease when interpreted by the on-site physician. The sensitivity of 111In-CYT-103 imaging was slightly lower when interpreted retrospectively by the blinded readers in the absence of any patient-specific information. 111In-CYT-103 imaging sensitivity was similar in patients with primary and recurrent disease, but lower for liver metastases than for extrahepatic disease. Thirty-three previously unknown lesions were visualized by immunoscintigraphy; tissue confirmation was available for only five lesions, and all were found to be free of tumor. Only one of the lesions evaluated was TAG-72 positive. Twenty-eight lesions were outside the surgical field or not biopsied. Although no tissue confirmation was available, seven (25%) of these lesions were identified as consistent with metastatic disease by other conventional modalities. Importantly, antibody scans detected occult tumor lesions in 11 of the 92 patients with surgically confirmed adenocarcinoma, and accurately diagnosed 7 of 10 patients with elevated serum CEA levels and negative conventional workup. Surgery confirmed the presence of tumor identified only by 111In-CYT-103 in three patients, while four patients with negative scans had no evidence of recurrent disease at surgery. Antibody scans confirmed the absence of additional disease in 18 of 22 patients with isolated hepatic or pelvic recurrences in whom curative surgery was contemplated. The results of this multicenter trial suggest that CYT-103 immunoscintigraphy can provide information that is complementary to that derived from standard diagnostic techniques. During the workup of patients with primary colorectal carcinoma, this modality assesses the entire body and allows for the identification of multiple lesions at various locations simultaneously. It can then redirect attention and further workup to those areas not originally surveyed. Of special interest in this regard is the identification of occult lesions in five patients with primary colorectal cancer. 111In-CYT-103 imaging was found superior to CT in the localization of primary colorectal cancer, but neither modality could adequately assess the extent of tumor penetration through the bowel wall (the T stage in the TNM system) or the N status. The limitations of CT in evaluating T and N are well documented, and the limitations of 111In-based immunoscintigraphy for these same lesions have recently been described. Another limitation of 111In-CYT-103 immunoscintigraphy is in the identification of liver metastases.(ABSTRACT TRUNCATED AT 400 WORDS)
Scaling Up Vision-Language Pre-training for Image Captioning (2021)

In recent years, we have witnessed significant performance boost in the image captioning task based on vision-language pre-training (VLP). Scale is believed to be an important factor for this advance. However, most existing work only focuses on pre-training transformers with moderate sizes (e.g., 12 or 24 layers) on roughly 4 million images. In this paper, we present LEMON, a LargE-scale iMage captiONer, and provide the first empirical study on the scaling behavior of VLP for image captioning. We use the state-of-the-art VinVL model as our reference model, which consists of an image feature extractor and a transformer model, and scale the transformer both up and down, with model sizes ranging from 13 to 675 million parameters. In terms of data, we conduct experiments with up to 200 million image-text pairs which are automatically collected from web based on the alt attribute of the image (dubbed as ALT200M). Extensive analysis helps to characterize the performance trend as the model size and the pre-training data size increase. We also compare different training recipes, especially for training on large-scale noisy data. As a result, LEMON achieves new state of the arts on several major image captioning benchmarks, including COCO Caption, nocaps, and Conceptual Captions. We also show LEMON can generate captions with long-tail visual concepts when used in a zero-shot manner.

Characteristics of Fertility Transition Response to the Cumulative Effective Low Temperature in a Two-Line Male Sterile Rice Cultivar (2021)

The fertility transition is caused mainly by the cumulative ELT. In two-line male sterile rice breeding, the effects of day length, ALT at night, and continuous response days should be considered together. The present study provides new insight into fertility transition so breeders can more effectively utilize the two-line male sterile rice, H93S, in breeding programs.

Analysis and optimization of reduced size printed monopole (2002)

A new structure of a shortened antenna operating at around 400 MHz is presented. The shortened monopole antenna using a step change line is printed on Duroid with a dielectric constant /spl epsi/r = 2.2 /spl plusmn/ 0.02 and thickness t = 0.8 /spl plusmn/ 0.02 mm. A shortening ratio of 51% is achieved. A simple analysis based on the transmission line model applied to printed dipole antennas, and the Babinet principle make it possible to optimize easily the geometry and the choice of ratio of the size of lines. The calculated results on input impedance are validated by experiment.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Multipli-Entangled Photons from a Spontaneous Parametric Down-Conversion Source (2011)

1. ABSTRACT In this work, we discuss a novel compact source that generates six pairs of entangled photons via spontaneous parametric down-conversion from a single pass of a pump beam through a crystal assembly. The experimental demonstrations reported are at 810 nm so as to utilize high quantum efficiency Si-APD detectors, but the design can be readily implemented in other wavelength regimes including the telecom bands near 1550 nm. An immediate application of this source enables particular multi-qubit cluster states to be generated in a highly compact unidirectional configuration. This can significantly simplify the interferometric stability, as well as feed-forward methods required in photon-based quantum logic circuitry.
Smart Q-switching for single-pulse generation in an erbium-doped fiber laser (2012)

In this paper, we report an active Q-switching of an erbium-doped fiber laser with special modulation functions and novel laser geometry. We experimentally demonstrate that using such a smart Q-switch approach, Q-switch ripple-free pulses with Gaussian-like shape and 17.3 ns width can be easily obtained. The idea behind the smart Q-switch is to suppress one of two laser waves contra-propagating along the fiber cavity, which arises after Q-cell opening, and to eliminate the minor sub-pulses.
IGF2 Is Up-regulated by Epigenetic Mechanisms in Hepatocellular Carcinomas and Is an Actionable Oncogene Product in Experimental Models (2016)

A large proportion of HCC samples were found to overexpress IGF2, via demethylation of its fetal promoter. Overexpression of IGF2 accelerates formation of liver tumors in mice with hepatic expression of MYC and AKT1, via activation of IGF1 receptor signaling. An antibody against IGF1 and IGF2 slows growth of xenograft tumors and increases survival of these mice.
IgA Nephropathy: Molecular Mechanisms of the Disease (2012)

Studies of molecular and cellular interactions involved in the pathogenesis of IgA nephropathy have revealed the autoimmune nature of this most common primary glomerulonephritis. In patients with this disease, altered glycan structures in the unique hinge region of the heavy chains of IgA1 molecules lead to the exposure of antigenic determinants, which are recognized by naturally occurring antiglycan antibodies of the IgG and/or IgA1 isotype. As a result, nephritogenic immune complexes form in the circulation and deposit in the glomerular mesangium. Deposited immune complexes induce proliferation of resident mesangial cells, increased production of extracellular matrix proteins and cytokines, and ultimately loss of glomerular function. Structural elucidation of the nature of these immune complexes and their biological activity should provide a rational basis for an effective, immunologically mediated inhibition of the formation of nephritogenic immune complexes that could be used as a disease-specific therapeutic approach.

High endothelial venules (HEVs) in human melanoma lesions (2012)

The presence of tumor-infiltrating lymphocytes (TILs) is a strong prognostic parameter for local dissemination and overall survival in melanoma. Lymphocyte migration from blood into peripheral tissues is mainly regulated by vascular endothelium. However, the blood vessels and mechanisms governing the recruitment of TILs in melanoma tumors remain poorly understood. Here, we show that high endothelial venules (HEVs), specialized blood vessels for lymphocyte extravasation into lymphoid tissues, are frequently found in melanoma tumors and are associated with high levels of lymphocyte infiltration. The analysis of 225 primary melanomas revealed that lymphocytes specifically infiltrated HEV-rich areas of melanoma tumors and that the density of MECA-79+ HEVs was variable among patients and strongly correlated with CD3+, CD8+ and CD20+ TIL densities. Inflammatory (CCL5, CXCL9, CXCL10 and CXCL11) and lymphoid (CCL21, CCL19 and CXCL13) chemokines as well as TH1 and naïve T-cell genes were overexpressed in melanoma samples with high densities of tumor HEVs. Mature dendritic cells (mDCs) were frequently found around tumor HEVs and densities of HEVs and DC-LAMP+ mDCs within tumor stroma were strongly correlated. DCs which maintain HEVs in lymph nodes, may thus also contribute to the regulation of HEVs in melanomas. Finally, we found significantly higher densities of tumor HEVs in melanomas with tumor regression, low Clark level of invasion and thin Breslow thickness (all p < 0.001). The strong association between tumor HEVs, TILs, mDCs and clinical parameters of melanoma, supports a critical role for HEVs in limiting malignant melanoma development through both naïve and effector T-lymphocyte recruitment and activation.
The Chemical Composition of the Essential Oils from the Leaves, Bark and Fruits of <i>Bursera simaruba</i> (L.) Sarg. from Jamaica (2008)

Abstract Oils of the leaves, bark and fruits of Bursera simaruba collected from the Long Mountain region of Jamaica were isolated by hydrodistillation and analyzed by GC-FID and GC/MS. From our analyses of the oils from the leaves, bark and fruits 46, 54 and 19 components were identified which constituted 93.6%, 97.9% and 100% of the total oils. The leaf oils were dominated by sesquiterpenes (70.1%), the major ones being trans-cadina-1(6),4-diene (9.7%) followed by β-caryophyllene (9.0%), α-humulene (6.2%), β-elemene (5.6%) α-cadinol (4.7%), α-selin-11-en-4-ol (4.2%), caryophyllene oxide (3.2%) and δ-selinene (3.1%). The major monoterpenes were α-pinene (10.2%), myrcene (5.2%) and β-pinene (3.4%). The major monoterpene components of the bark were α-pinene (32.1%), β-pinene (13.5%) and isolimonene (5.6%) while the major sesquiterpenes were viridiflorol (7.1%), β-caryophyllene (4.9%), β-selinene (4.3%), α-humulene (3.1%) and caryophyllene oxide (3.1%). The fruit oil was characterized by a high portion of monoterpenes, the major ones being α-pinene (27.8%), β-pinene (24.1%), terpinen-4-ol (13.3%), sabinene (8.1%), iso-sylvestrene (4.9%), limonene (4.4%) and γ-terpinolene (3.5%).
Transcriptomic alterations in the heart of non-obese type 2 diabetic Goto-Kakizaki rats (2016)

Interleukin-12 Antagonists as New Therapeutic Agents in Inflammatory Bowel Disease (2002)

Inflammatory bowel diseases (IBDs; Crohn's disease (CD) and ulcerative colitis) are chronic inflammatory diseases leading to destruction of gastrointestinal tissue. They are characterized by an exaggerated immune response. In CD, an increased expression of T-helper-1 (Th1) cytokines was observed in which interleukin-12 (IL-12) seems to play a pivotal role. Different immunosuppressive agents have been used to treat patients suffering from IBD, nevertheless remarkable side effects or treatment failure are limiting factors in this regard. Therefore, studies on more specific treatment of CD have recently been published, using recombinant anti-inflammatory cytokines or inhibitors of proinflammatory cytokines and their receptors. Beyond these principles anti-IL-12 strategies seem to play a promising role because of the central position of this Th1-inducing cytokine in the inflammatory cascade. Up to now anti-IL-12 antibodies, complement receptor-3 antibodies and IL-12p40 homodimers have been evaluated in their potential to suppress the mucosal inflammation. Based on our understanding of the pathogenesis of CD, the available data and experiences concerning these principles are presented in this review.
