Controlling Biosolids Phosphorus Content in Enhanced Biological Phosphorus Removal Reactors (2003)

A methodology to reduce the phosphorus content of biosolids produced by enhanced biological phosphorus removal treatment plants was studied. The process consists of mixing phosphate-rich waste activated sludge (WAS) with either primary sludge or the supernatant from a primary-sludge gravity thickener under anaerobic conditions to induce the release of phosphate from WAS. The solubilized phosphate could then be chemically sequestered and removed from the biosolids. Bench-scale phosphate release experiments were conducted with sludge from the Nine Springs Wastewater Treatment Plant (Madison, Wisconsin) at different mixing ratios. A WAS/primary sludge or WAS/supernatant mixing ratio of 1:1 (by volume) resulted in the highest phosphate release in the batch tests. For experiments with less than 50% WAS (by volume), the total phosphate release was directly proportional to the amount of WAS added. When the mixture contained more than 50% WAS, total phosphate release was limited by the volatile fatty acids (VFAs) available. For the Nine Springs plant optimal biosolids phosphorus could be achieved using a primary sludge/WAS mixing ratio of 1.02 kg volatile suspended solids (VSS)/kg VSS or a supernatant VFA/WAS mixing ratio of 0.028 kg VFA/kg VSS. The expected reduction in phosphorus content would be 35 and 32% if primary sludge or supernatant, respectively, were used.
Clarification of the low-lying states of<sup>9</sup>Be (2006)

A newly developed technique for dealing with three-body decays of broad isolated levels is extended to deal with the broad, overlapping levels found at 2-9 MeV excitation energy in 9 Be. The levels are populated through beta-decay of 9 Li. The method gives firm evidence for the existence of several levels. Angular correlation studies allow spin values to be assigned.
Biologically inspired vision sensor for the detection of higher-level image features (2004)

The paper briefly reviews certain aspects of the biological visual system and presents a smart vision sensor for the detection of higher-level features. The visual system processes information in a hierarchical manner starting from the retina up to the visual cortex. It decomposes the image in simple features (edges, orientation, line stops, corners, etc) using spatial and temporal information. At the higher level it integrates these primitive features, resulting in the recognition of complex objects. The sensor described in the paper is loosely modeled after the visual system and incorporates pixel level, programmable elements which extract orientation, end stops, corners and junctions from a line drawing. The architecture resembles a CNN-UM that can be programmed with a 30-bit word. The 16/spl times/16 pixels array detects these higher-level features in about 54 /spl mu/s.
Computational Study of the Influence of the Binding Geometries of Organic Ligands on the Photoluminescence Quantum Yield of CdSe Clusters (2016)

This article describes density-functional-theory- (DFT-) based calculations of the rate constants for radiative (kR) and nonradiative (kNR) decay from the lowest singlet excited state (S1) to the ground state (S0) of a Cd16Se13 cluster ligated with various molecules in various binding geometries. The value of kR is suppressed by ligands whose localized orbitals, as a result of their binding geometry, become the cluster’s frontier orbitals and, thereby, decrease the overlap of the electron densities of the HOMO and LUMO necessary for efficient dipole coupling. Thiolate ligands in a monodentate geometry and dithioate ligands in a bridging geometry decrease kR in this manner. The value of kNR is also sensitive to the binding geometries of the ligands: binding geometries that are less rigid yield a greater change in nuclear coordinates between the S1 and S0 electronic states, which, in turn, increases the rate of nonradiative decay by maximizing the vibronic coupling between the band-edge exciton and the vibrational modes of the ligands. This work suggests that the photoluminescence quantum yield of CdSe nanoparticles can be maximized by ensuring that the bridging binding mode is the dominant binding mode of the ligands; bridging modes decrease the nonradiative decay rate and eliminate mid-band-gap trap states in all cases studied, except for dithioate ligands.
Gene dosage alterations revealed by cDNA microarray analysis in cervical cancer: Identification of candidate amplified and overexpressed genes (2007)

Cervical cancer (CC) cells exhibit complex karyotypic alterations, which is consistent with deregulation of numerous critical genes in its formation and progression. To characterize this karyotypic complexity at the molecular level, we used cDNA array comparative genomic hybridization (aCGH) to analyze 29 CC cases and identified a number of over represented and deleted genes. The aCGH analysis revealed at least 17 recurrent amplicons and six common regions of deletions. These regions contain several known tumor-associated genes, such as those involved in transcription, apoptosis, cytoskeletal remodeling, ion-transport, drug metabolism, and immune response. Using the fluorescence in situ hybridization (FISH) approach we demonstrated the presence of high-level amplifications at the 8q24.3, 11q22.2, and 20q13 regions in CC cell lines. To identify amplification-associated genes that correspond to focal amplicons, we examined one or more genes in each of the 17 amplicons by Affymetrix U133A expression arrays and semiquantitative reverse-transcription PCR (RT-PCR) in 31 CC tumors. This analysis exhibited frequent and robust upregulated expression in CC relative to normal cervix for genes EPHB2 (1p36), CDCA8 (1p34.3), AIM2 (1q22-23), RFC4, MUC4, and HRASLS (3q27-29), SKP2 (5p12-13), CENTD3 (5q31.3), PTK2, RECQL4 (8q24), MMP1 and MMP13 (11q22.2), AKT1 (14q32.3), ABCC3 (17q21-22), SMARCA4 (19p13.3) LIG1 (19q13.3), UBE2C (20q13.1), SMC1L1 (Xp11), KIF4A (Xq12), TMSNB (Xq22), and CSAG2 (Xq28). Thus, the gene dosage and expression profiles generated here have enabled the identification of focal amplicons characteristic for the CC genome and facilitated the validation of relevant genes in these amplicons. These data, thus, form an important step toward the identification of biologically relevant genes in CC pathogenesis.

Baseline Maternal Body Mass Index Compared With Body Mass Index at Delivery as a Predictor of Neonatal Outcomes in Obese Pregnant Women [95] (2015)

INTRODUCTION: The study was conducted to analyze whether baseline body mass index (BMI, calculated as weight (kg)/[height (m)]2) at initiation of prenatal care in pregnant women with BMIs greater than 30 affects neonatal outcomes more than pregnancy weight gain or BMI at delivery. METHODS: A retrospective cohort study of 175 singleton pregnancies managed at Queens Hospital Center from January 2013 to December 2013 were included in the study. Inclusion criteria were maternal BMI greater than 30 at initiation of prenatal care (before 16 weeks of gestation), singleton gestation, and delivery during the study period. Exclusion criteria were multiple gestations, fetal anomalies, and gestational and pregestational diabetes. Group A had BMI 30–34.9 (114 patients), group B had BMI 35–39.9 (42 patients), and group C had BMI greater than 40 (19 patients). Groups were analyzed with respect to baseline demographic parameters and neonatal outcomes: birth weight, neonatal intensive care unit (NICU) admission, and length of hospital stay. Spearman's correlation coefficient, analysis of variance, and χ2 were used for statistical analysis. RESULTS: Across the three groups, the neonatal birth weight significantly correlated with maternal weight gain in pregnancy and weight gain at delivery but did not correlate with maternal baseline weight and BMI at initiation of prenatal care (P=.04). The mode of delivery, the rate of NICU admission, and length of stay did not demonstrate any association with either baseline BMI or BMI at delivery across all three groups. CONCLUSION: Maternal BMI at delivery and not baseline BMI at initiation of prenatal care is directly associated with neonatal birth weight in pregnancies complicated by maternal obesity. Neither BMI at initiation of prenatal care nor at the time of delivery is associated with mode of delivery, rate of NICU admission, or neonatal hospital stay.

Aerobic Oxidation of Methylpyridines to Pyridinecarboxylic Acids Catalyzed by <i>N</i>-Hydroxyphthalimide (2000)

Selective aerobic oxidation of methylpyridines to pyridinecarboxylic acids was successfully achieved by the use of a radical catalyst, N-hydroxyphthalimide (NHPI), in the presence of Co(II) and/or Mn(II) salts. The oxidation of 3-methylpyridine by NHPI combined with Co(OAc)2 under O2 (1 atm) in AcOH at 100 °C gave 3-pyridinecarboxylic acid (76%). The reaction was found to be enhanced by addition of a small amount of Mn(OAc)2 to the catalytic system. The reaction with 20 atm of air, catalyzed by NHPI−Co(OAc)2−Mn(OAc)2 at 150 °C for 1 h, gave 3-pyridinecarboxylic acid (85%). 4-Methylpyridine was much less easily oxidized than 3-methylpyridine. The co-oxidation of 3-methylpyridine and 4-methylpyridine by NHPI−Co(OAc)2−Mn(OAc)2 at 150 °C for 5 h gave results that were better than those obtained from individual oxidations, forming 3-pyridinecarboxylic acid (93%) and 4-pyridinecarboxylic acid (70%). The NHPI-catalyzed oxidation of methylpyridines would provide an attractive direct method which has long been desired in the chemical industry for the manufacturing of pyridinecarboxylic acids.

Two‐Terminal Multibit Optical Memory via van der Waals Heterostructure (2018)

2D van der Waals (vdWs) heterostructures exhibit intriguing optoelectronic properties in photodetectors, solar cells, and light-emitting diodes. In addition, these materials have the potential to be further extended to optical memories with promising broadband applications for image sensing, logic gates, and synaptic devices for neuromorphic computing. In particular, high programming voltage, high off-power consumption, and circuital complexity in integration are primary concerns in the development of three-terminal optical memory devices. This study describes a multilevel nonvolatile optical memory device with a two-terminal floating-gate field-effect transistor with a MoS<sub>2</sub> /hexagonal boron nitride/graphene heterostructure. The device exhibits an extremely low off-current of ≈10<sup>-14</sup> A and high optical switching on/off current ratio of over ≈10<sup>6</sup> , allowing 18 distinct current levels corresponding to more than four-bit information storage. Furthermore, it demonstrates an extended endurance of over ≈10<sup>4</sup> program-erase cycles and a long retention time exceeding 3.6 × 10<sup>4</sup> s with a low programming voltage of -10 V. This device paves the way for miniaturization and high-density integration of future optical memories with vdWs heterostructures.
The Second EWGRD Round Robin: Inter-Comparison of<sup>93m</sup>Nb Measurements (2023)

Following on from an initial Round Robin inter-comparison of gamma spectrometry measurements reported in 2014, this paper presents the results of the second part of a further Round Robin inter-comparison commissioned in 2018 by the European Working Group on Reactor Dosimetry. The purpose of the exercise was to demonstrate the level of consistency between different organisations’ measurements of the 93 Nb(n,n’) 93m Nb reaction, which plays a key role in underwriting reactor dosimetry assessments. To achieve this, measurements of 93m Nb activity were performed by twelve European organisations on six sets of near identical niobium samples, each having its own geometry and tantalum concentration. The samples were provided by CEA, France and irradiated in the MARIA reactor, operated by National Centre for Nuclear Research, Poland. Participants provided their results to an independent referee who collated and compared the data. The inter-comparison has demonstrated agreement to within standard deviations ranging from ±2.2% to ±7.9%, with a tendency for some organisations to measure elevated values. The results of the inter-comparison are presented in an anonymised form together with discussion and conclusions which may be drawn from the exercise.
Slicing of Constraint Logic Programs. (2000)

Slicing is a program analysis technique originally developed for imperative languages. This paper discusses slicing of CLP programs. As data flow in such programs is not explicit, the slicing problem requires a specific formulation and specific techniques. The paper gives a precise definition of the slicing problem for CLP and presents a simple slicing method based on variable sharing and groundness analysis. Our approach is based on three declarative notions of slice: (1) for a set of constraints (2) for a derivation tree of a CLP program, and (3) for a CLP program. The first of them is a basic one, expressed in terms of logic and used to define the remaining ones. A derivation tree of a CLP program characterizes a state of the computation of a CLP program in terms of the associated set of constraints. We use the notion of slice of a set of constraints to introduce the notion of slice of a derivation tree. A derivation tree is constructed from instances of program clauses. We define the notion of slice of a program in terms of slices of its derivation trees. With these definitions we obtain clear links between all three concepts of a slice. They make it possible to derive slicing techniques for derivation trees and CLP programs by refining some straightforward syntactic conditions which can be easily checked. The declarative formulation of the slicing problem leaves space for possible improvements and gives a clear reference basis for proving the correctness of the proposed slicing methods.

Fast-Charging of Automotive Lithium-Ion Cells: In-Situ Lithium-Plating Detection and Comparison of Different Cell Designs (2020)

Fast-charging is a key requirement for customer acceptance of battery electric vehicles. In this work, various methods for lithium-plating detection are applied to prismatic hard-case lithium-ion cells to demonstrate their applicability for large-format automotive cells despite possible thermal and electrochemical inhomogeneities. Different fast-charging profiles with a charging time of less than 30 min from 10% to 80% state-of-charge are examined with methods based on coulombic efficiency, cell voltage analysis and swelling force. To validate these results, a lifetime cycling test with a subsequent cell opening is performed, followed by a discussion on lithium-plating detectability and the restrictions of each method. In order to further illustrate the applicability of the lithium-plating detection methods, the fast-charging ability of two cells with the same format but different cathode active materials, namely NMC622 and NMC811, are compared. Furthermore, a coupled electrochemical-thermal simulation is performed to study the effect of the cell design on the fast-charging ability and to elucidate why a higher cell energy density does not necessarily lead to a worse fast-charging ability.
Permanent Suspensions in Optical Lapping and Polishing (1988)

In optical fabrication shops many times the polishing and lapping slurries are thrown together without much thought or concern about the complex system that exists in that slurry. Many times the way the slurry is prepared can make the difference between mediocrity and perfection in the finished parts.
Perpendicular Recording with Reduced Skew Angle Sensitivity (2008)

A detailed analysis to the problem of skew angle sensitivity in perpendicular magnetic recording is presented. A proposed analytical model is supported by numerical simulations with a commercial boundary element software program. According to the presented equivalent magnetic circuit model, a single pole recording head with a laminated composition involving two layers of different magnetic materials could be used to localize adequately strong magnetic field in the vicinity of the trailing edge of the recording head. It is shown that the recording field generated under each lamination layer is proportion to the relative magnetic permeability of the respective layer. Such localization of the magnetic flux results in substantially reduced skew angle sensitivity.
Genetic control of immunoregulatory circuits. Genes linked to the Ig locus govern communication between regulatory T-cell sets. (1979)

Antigen-stimulated Ly1:Qa1+ cells induce a nonimmune set of T-acceptor cells (surface phenotype Ly123+Qa1+) to participate in the generation of specific suppressive activity. The experiments reported here were designed to test the possibility that the interaction between T-inducer and T-acceptor cells might be governed by genes linked to the Ig locus. We find that inducer:acceptor interactions occur only if the inducer and acceptor T-cell sets are obtained from donor that are identical at the Ig locus and are independent of the Ig locus expressed on the B cells used for assay of T-helper activity. In addition, experiments using inducer and acceptor T cells from the congenic recombinant BAB. 14 strain show that T-T interactions are not governed by Ig-CH genes, per se. These data indicate that T-inducer: T-acceptor interactions are governed by Ig-linked genes that may control expression of VH-like structures on T cells, or control expression of as yet unidentified cell-surface molecules.
RNA Editing of Tumor Suppressor Mir-26a Promotes Malignant Progenitor Propagation in Chronic Myeloid Leukemia (2018)

Abstract Recent studies demonstrate the importance of post-transcriptional adenosine-to-inosine (A-to-I) RNA editing mediated by adenosine deaminase acting on RNA1 (ADAR1) in normal fetal and adult hematopoiesis. RNA-sequencing studies have shown that elevated levels of the ADAR1 editase has emerged as a dominant driver of cancer progression and therapeutic resistance. Specifically, the deregulation of ADAR1 promotes the transformation of chronic myeloid leukemia (CML) from chronic phase (CP) to a therapy resistant blast crisis (BC) phase. Through the regulation of mRNA and microRNA (miRNA) stability, ADAR1 plays a pivotal role in embryonic development and stem cell regulation. We have previously shown that inflammation-responsive ADAR1 heavily contributes to stem cell differentiation and self-renewal in CML disease progression. Here, we describe a novel role of ADAR1 in cell cycle regulation of BC leukemia cells through regulation of miRNA biogenesis. To investigate the role of ADAR1 in miRNA regulation, we performed miRNome miScript PCR array analysis of 1008 miRNAs in cord blood CD34+ expressing hematopoietic stem and progenitor cells (HSPCs) overexpressing ADAR1 wild type (WT) and A-to-I editing deficient ADAR1 mutant. Overall, a total of 112 miRNAs were significantly differentially expressed following ADAR1 expression with cell cycle identified as the top cellular pathway significantly targeted by miRNAs regulated by ADAR1. Notably, ADAR1 editase activity inhibits the expression of miR-26a-5p, a tumor suppressor miRNA that is frequently downregulated in BC CML. ADAR1 inhibits miR-26a-5p through direct editing of the DROSHA cleavage site of primary miR-26a-5p, preventing miR-26a-5p maturation and processing. In normal hematopoietic progenitors, ADAR1-mediated inhibition of miR-26a results in repression of cyclin-dependent kinase inhibitor 1A (CDKN1A) expression indirectly via suppression of the polycomb repressive complex, enhancer of zeste homolog 2 (EZH2), thereby accelerating cell cycle transit. However, in BC CML progenitors, decreased EZH2 and increased CDKN1A oppose the cell cycle accelerating effect of ADAR1. Moreover, we found that the miR-26a targets a different set of mRNA in BC CML compared to cord blood HSPC and has divergent roles in cell cycle regulation. Lentiviral miR-26a overexpression reduced BC leukemia stem cell (LSC) dormancy in the bone marrow and reverses the functional effects of ADAR1, including inhibition of BC cell proliferation in vivo and impaired LSC self-renewal capacity as measured by colony forming assays. Our finding reveals the effects of ADAR1 in LSC generation through impairing biogenesis of cell cycle regulatory miRNAs. The deregulation of ADAR1 contributes to the malignant reprogramming of progenitors into dormant LSCs that are resistant to therapeutic treatments. Future development of ADAR1 inhibitors may be effective in the elimination of dormant BC CML LSCs that evade tyrosine kinase inhibitors. Disclosures No relevant conflicts of interest to declare.
