SELECTIVE REMOVAL OF CESIUM FROM HIGHLY CONCENTRATED SODIUM NITRATE NEUTRAL SOLUTIONS BY POTASSIUM NICKEL HEXACYANOFERRATE(II)-LOADED SILICA GELS (1999)

ABSTRACT Potassium nickel hexacyanoferrate(II) (KNiFC)-loaded silica gels were prepared by successive impregnation of macro pores with Ni(NO3)2, and K4Fe(CN)6 solutions. The KNiFC precipitates uniformly dispersed in the matrix of silica gel, and the loading percentage of KNiFC increased with the number impregnation cycles. The uptake of Cs+ on KNiFC-loaded silica gels (SLFC) attained equilibrium within 2 d, and relatively large distribution coefficients of Cs+, Kd,cs, above 104 cm3/g, were obtained even in the presence of 5 M NaNO3. The ion exchange of K+ Cs+ in SLFC followed a Langmuir-type isotherm and the maximum uptake amount of Cs+ was estimated to be 0.305 mmol/g. The breakthrough curve of Cs+ through a column packed with SLFC exhibited a favorable S-shaped profile. This exchanger proved to be effective for the selective removal of radioactive cesium from neutral waste solutions containing highly concentrated NaNO3.
MIMO Channel Information Feedback Using Deep Recurrent Network (2018)

In a multiple-input multiple-output (MIMO) system, the availability of channel state information (CSI) at the transmitter is essential for performance improvement. Recent convolutional neural network (NN)-based techniques show competitive ability in realizing CSI compression and feedback. By introducing a new NN architecture, we enhance the accuracy of quantized CSI feedback in MIMO communications. The proposed NN architecture invokes a module named long short-term memory that admits the NN to benefit from exploiting temporal and frequency correlations of wireless channels. Compromising performance with complexity, we further modify the NN architecture with a significantly reduced number of parameters to be trained. Finally, experiments show that the proposed NN architectures achieve better performance in terms of both CSI compression and recovery accuracy.
Long-term Effects of Human Herpesvirus 6 Infection (2008)

To the Editor .—

In 1969, I was living in Seoul, South Korea, and serving as a consultant to Holt Adoption Agency. I had arranged to escort a Korean orphan to his adoptive parents in the United States. He was a 6-month-old male infant who had had a break in his left arm; the infection had reached his bone, and he was running a fever of 102 to 103°F. On the day before our flight, his doctor asked me to consult on a rash of tiny gray vesicles that the infant had developed on the lower …
Structure determination of phosphoinositol oligosaccharides from parasitic protozoa using fast atom bombardment mass spectrometry (1994)

Abstract Glycosylphosphatidylinositols (GPIs) are widely distributed membrane constituents of protozoa and higher eukaryotes, where they anchor proteins and other macromolecules to the cell surface. Free glycosylinositol phospholipids (i.e. not attached to protein or polysaccharide) have also been detected in some parasitic protozoa, and are thought play a role in the interaction of parasite and host. This paper describes the fast atom bombardment mass spectrometry (FABMS) of glycosylinositol phospholipids from the Trypanosomatid parasites Leptomonas samueli, Endotrypanum schaudinni and Leishmania adleri . FABMS in the positive‐and negative‐ion modes in conjunction with collisional activation permits the rapid determination of the monosaccharide composition, the sequence of residues, the branching pattern and the nature and location of non‐carbohydrate substituents. When supplemented by high‐field NMR, FABMS provides a highly efficient route to the complete structure elucidation of these materials.

On the behavior of congestion minimization during placement (1999)

Typical placement objectives involve reducing net-cut cost or minimizing wirelength. Congestion minimization is least understood, however, it models routability accurately. In thii paper, we study the congestion minimization problem during placement. We introduce the notion of consistent routing model and promote its adoption by placement systems. First, we show that in thii model the wirelength objective is indeed a good measure of congestion by establishing that a placement with minimum wirelength has minimum total congestion. We show that miniibmg wirelength may (and in general, will) create locally congested regions. We demonstrate that most other congestion related objectives are ill behaved and they should only be used in a post processing step. We then propose several novel congestion minimization objectives. One in psrticulsr, called overflow minimization with look-ahead, performs very well and can be computed very efficiently in an incremental manner. At the end, we propose a post processing phase that further improves the congestion. By combining the overflow minimization with look-ahead and the post processing phase, we improve the congestion by more than 40% on the average.
Prevention of Type 2 Diabetes in Subjects With Prediabetes and Metabolic Syndrome Treated With Phentermine and Topiramate Extended Release (2013)

OBJECTIVE To evaluate over 108 weeks the effect of phentermine and topiramate extended release (PHEN/TPM ER) treatment on progression to type 2 diabetes and/or cardiometabolic disease in subjects with prediabetes and/or metabolic syndrome (MetS) at baseline. RESEARCH DESIGN AND METHODS Subanalysis of a phase 3, randomized, placebo-controlled, double-blind study of overweight/obese subjects (BMI ≥27 to ≤45 kg/m(2)) with two or more comorbidities. Subjects were randomized to placebo, PHEN 7.5 mg/TPM ER 46 mg (7.5/46), or PHEN 15 mg/TPM ER 92 mg (15/92) plus lifestyle modifications for 108 weeks. Percent weight loss in the intent-to-treat population using multiple imputation (ITT-MI), annualized incidence rate of progression to type 2 diabetes, and changes in glycemia, lipid parameters, blood pressure, and waist circumference were evaluated. RESULTS At baseline, 475 subjects met the criteria for prediabetes and/or MetS. After 108 weeks, subjects with prediabetes and/or MetS in the placebo, 7.5/46, and 15/92 groups experienced mean percent weight loss of 2.5, 10.9, and 12.1%, respectively (ITT-MI; P < 0.0001 vs. placebo), associated with reductions of 70.5 and 78.7% in the annualized incidence rate of type 2 diabetes for those receiving 7.5/46 and 15/92, respectively (ITT, P < 0.05), versus placebo. The ability of PHEN/TPM ER to prevent diabetes was related to degree of weight lost and was accompanied by significant improvements in cardiometabolic parameters. PHEN/TPM ER was well tolerated by this subgroup over 2 years. CONCLUSIONS PHEN/TPM ER plus lifestyle modification produced significant weight loss and markedly reduced progression to type 2 diabetes in overweight/obese patients with prediabetes and/or MetS, accompanied by improvements in multiple cardiometabolic disease risk factors.
A Quick Algorithm to Search and Detect Video Shot Changes (2015)

The cost of video processing computation is very high and shot boundary detection is one of the reasons for this cost. Shot?s scope determination is an essential part in most of the video processing applications, especially for video indexing and content based video retrieval. This paper introduces a fast algorithm for searching the shots region and detecting their location, based on the divide and conquers technique. The main advantage of this method is due to skipping large parts of the video in the search step, which results in computational load reduction, leading to detection speed increase.
Dye-Sensitized TiO<sub>2</sub> Solar Cells Using Imidazolium-Type Ionic Liquid Crystal Systems as Effective Electrolytes (2007)

A novel ionic liquid crystal (ILC) system (C(12)MImI/I(2)) with a smectic A phase used as an electrolyte for a dye-sensitized solar cell (DSSC) showed the higher short-circuit current density (J(SC)) and the higher light-to-electricity conversion efficiency than the system using the non-liquid crystalline ionic liquid (C(11)MImI/I(2)), due to the higher conductivity of ILC. To investigate charge transport properties of the electrolytes in detail, the exchange reaction-based diffusion coefficients (D(ex)) were evaluated. The larger D(ex) value of ILC supported that the higher conductivity of ILC is attributed to the enhancement of the exchange reaction between iodide species. As a result of formation of the two-dimensional electron conductive pathways organized by the localized I(3)- and I- at S(A) layers, the concentration of polyiodide species exemplified by I(m)- (m = 5, 7, ...) was higher in C(12)MImI/I(2). However, as the increment of the concentration of polyiodide species is less than that of D(ex), the contribution of a two-dimensional structure of the conductive pathway through the increase of collision frequency between iodide species was proposed. Furthermore, a quasi-solid-state ionic liquid crystal DSSC was successfully fabricated by employing a low molecular gelator. Addition of the 5.0 g/L gelator to ILC improved light-to-electricity conversion efficiency through the increase of J(SC) due to the enhancement of the conductivity in C(12)MImI/I(2)-gel.
RFID Platform as a Service, Containerized Ecosystem, Feasibility and Security Impact Analysis (2015)

This paper presents a new concept as a special type of virtualization of particular event based communication components in RFID ecosystems. The new approach is containers based virtualization, and it is applied and tested on the container of Object name service. The results of the experiment allowed us to do the preliminary analysis of security consequences on the isolated containerized DNS-based RFID sub-service. We confirmed feasibility with this sandboxing technology represented by the special container. They bring the benefits in terms of efficient software component life-cycle management and integrity improvements. Experiments results of the containerization are discussed to show the possible isolation ways of other components like EPCis and middleware. There is present evaluation towards external threats and vulnerabilities. The result is a higher level of integrity, availability of whole ecosystem and resiliency against external threats. This gives a new opportunity to build robust RFID as Platform as a service, and it proves the ability to achieve a positive impact on the end to end service Quality of service.
Intracellular free calcium level and its response to cAMP stimulation in developing <i>Dictyostelium</i> cells transformed with jellyfish apoaequorin cDNA (1994)

A new method is described for measuring intracellular free calcium concentrations, [(Ca2+)i], in the cells of Dictyostelium discoideum transformed with apoaequorin cDNA of the jellyfish, Aequorea victoria. Aequorin, a calcium-specific indicator, was regenerated in vivo from apoaequorin produced in the cells by incubation with coelenterazine. The results showed that [(Ca2+)i] in developing cells markedly increases at the aggregation stage and again at the culmination stage after a temporary drop at the migration stage. Except for the vegetative stage, the cells at all stages of development exhibit a sharp transient increase in [(Ca2+)i] upon stimulation with a cAMP (50 nM) pulse, high responses being observed at the migration and culmination stages. Separated prestalk cells of migrating slugs contain more than twice as much [(Ca2+)i] and show three times as large a response to cAMP stimulation as prespore cells.
Phenotypes in chronic B-lymphocytic leukemia probed by monoclonal antibodies and immunoglobulin secretion studies: identification of stages of maturation arrest and the relation to clinical findings (1983)

Neoplastic populations from 25 cases of B-lymphocytic leukemia (B-LL) were investigated in an attempt to define the stages of maturation arrest represented in this disease and the relationship, if any, to various clinical parameters. Intrinsic to this study was the expression of a number of B-cell antigens defined by monoclonal antibodies. These included antibodies to B1 and B2, both expressed exclusively on B lymphocytes, but with the latter probably restricted to a narrow window of differentiation, BB-1 and LB-1, both markers of activated lymphocytes, and 38.13, a monoclonal antibody raised against and recognizing an epitope expressed on Burkitt lymphoma cells. While the patterns of reactivities were complex, the cases could be classified into various groups on the basis of the phenotypes revealed. These were termed “pre-B,” “early-B,” “intermediate-B,xyc “mature-B,” and “secretory- B” from their patterns of immunoglobulin (Ig) isotype expression and their capacity to secrete Ig in short-term culture. Although B1 was detected on neoplastic cells from all but one case, its intensity of expression varied markedly, being strongest on the “mature-B” and “secretory-B” cases and weakest on the “pre-B” type. The expression of B2 was essentially restricted to the “intermediate-B,” “mature-B,” and “secretory-B” cases and was usually, but not invariably, accompanied by the coexpression of surface IgM and IgD. While expression of BB-1 was restricted to a few cases with mature features, LB-1 was more frequently detected and found predominantly on “intermediate-B” and “mature-Bxyc cases. The 38.13 antibody was found to react weakly with a number of the populations coexpressing IgM and IgD. The export of large amounts of whole Ig was restricted to three “secretory-B” cases all of which were associated with a serum M-component corresponding to the Ig isotype secreted in vitro. In contrast, the secretion of free Ig light chains was a consistent feature of all B-LL, and the amounts detected did not vary considerably between the different types. No correlation between immunologic cell-type and the stage of the disease was apparent. Classification of the cases into “true” B-chronic lymphocytic leukemia and immunocytoma similarly revealed no strict association of these histopathologic entities with any particular phenotypic group, although those cases with the more mature features tended to be immunocytomas. The findings are discussed within the context of normal B-cell differentiation pathways.
A Functional Null Mutation of<i>SCN1B</i>in a Patient with Dravet Syndrome (2009)

Dravet syndrome (also called severe myoclonic epilepsy of infancy) is one of the most severe forms of childhood epilepsy. Most patients have heterozygous mutations in SCN1A, encoding voltage-gated sodium channel Na(v)1.1 alpha subunits. Sodium channels are modulated by beta1 subunits, encoded by SCN1B, a gene also linked to epilepsy. Here we report the first patient with Dravet syndrome associated with a recessive mutation in SCN1B (p.R125C). Biochemical characterization of p.R125C in a heterologous system demonstrated little to no cell surface expression despite normal total cellular expression. This occurred regardless of coexpression of Na(v)1.1 alpha subunits. Because the patient was homozygous for the mutation, these data suggest a functional SCN1B null phenotype. To understand the consequences of the lack of beta1 cell surface expression in vivo, hippocampal slice recordings were performed in Scn1b(-/-) versus Scn1b(+/+) mice. Scn1b(-/-) CA3 neurons fired evoked action potentials with a significantly higher peak voltage and significantly greater amplitude compared with wild type. However, in contrast to the Scn1a(+/-) model of Dravet syndrome, we found no measurable differences in sodium current density in acutely dissociated CA3 hippocampal neurons. Whereas Scn1b(-/-) mice seize spontaneously, the seizure susceptibility of Scn1b(+/-) mice was similar to wild type, suggesting that, like the parents of this patient, one functional SCN1B allele is sufficient for normal control of electrical excitability. We conclude that SCN1B p.R125C is an autosomal recessive cause of Dravet syndrome through functional gene inactivation.
Variable Length Coding for Increasing Traffic Capacity in PCM Transmission Systems (1973)

The probability density function of PCM encoded speech signals has been measured, and it has been found that, as a result of companding, the distribution is rather flat except in the neighborhood of the zero level. On the basis of the measured probability density function (PDF) a variable length prefix code was developed that allows an increase in the traffic capacity of PCM transmission systems. The benefit obtained is mainly due to the high probability of the zero level. According to the proposed coding method, inactive channels are maintained by sending only one code bit per frame; they thus can be activated without delay and without signaling. This is an advantage with respect to the time assignment speech interpolation (TASI) system [1].In the paper the capability of this method has been investigated.
Importance of Protein Kinase C Targeting for the Phosphorylation of Its Substrate, Myristoylated Alanine-rich C-kinase Substrate (2000)

We visualized the translocation of myristoylated alanine-rich protein kinase C substrate (MARCKS) in living Chinese hamster ovary-K1 cells using MARCKS tagged to green fluorescent protein (MARCKS-GFP). MARCKS-GFP was rapidly translocated from the plasma membrane to the cytoplasm after the treatment with phorbol ester, which translocates protein kinase C (PKC) to the plasma membrane. In contrast, PKC activation by hydrogen peroxide, which was not accompanied by PKC translocation, did not alter the intracellular localization of MARCKS-GFP. Non-myristoylated mutant of MARCKS-GFP was distributed throughout the cytoplasm, including the nucleoplasm, and was not translocated by phorbol ester or by hydrogen peroxide. Phosphorylation of wild-type MARCKS-GFP was observed in cells treated with phorbol ester but not with hydrogen peroxide, whereas non-myristoylated mutant of MARCKS-GFP was phosphorylated in cells treated with hydrogen peroxide but not with phorbol ester. Phosphorylation of both MARCKS-GFPs reduced the amount of F-actin. These findings revealed that PKC targeting to the plasma membrane is required for the phosphorylation of membrane-associated MARCKS and that a mutant MARCKS existing in the cytoplasm can be phosphorylated by PKC activated in the cytoplasm without translocation but not by PKC targeted to the membrane.

Adaptive Constraint and Rule-Based Product Bundling in Enterprise Networks (2014)

Product bundling refers to the combination of several products for sale as one product. Current bundling approaches lack the ability to adapt, focusing mostly on the creation of pre-computed static bundles, which prove to be inefficient considering the dynamically changing prospective customer needs and product availability, as is particularly the case in enterprise networks. This paper describes a novel approach for dynamic generation of personalized, constrained and rule-based product bundles in such environments. The proposed agent-based approach involves estimation of substitution and complementarity associations between products and constructing bundles according to individual customer preferences. The process adapts automatically to changing circumstances, such as customer profile, product availability and constraint and rule diversity. The proposed approach is discussed in the context of e-Furniture, an agent-based system supporting networking of furniture and wood product manufacturing enterprises.
The <i>REVOLUTA</i> gene is necessary for apical meristem development and for limiting cell divisions in the leaves and stems of <i>Arabidopsis thaliana</i> (1995)

The form of seed plants is determined by the growth of a number of meristems including apical meristems, leaf meristems and cambium layers. We investigated five recessive mutant alleles of a gene REVOLUTA that is required to promote the growth of apical meristems and to limit cell division in leaves and stems of Arabidopsis thaliana. REVOLUTA maps to the bottom of the fifth chromosome. Apical meristems of both paraclades (axillary shoots) and flowers of revoluta mutants frequently fail to complete normal development and form incomplete or abortive structures. The primary shoot apical meristem sometimes also arrests development early. Leaves, stems and floral organs, in contrast, grow abnormally large. We show that in the leaf epidermis this extra growth is due to extra cell divisions in the leaf basal meristem. The extent of leaf growth is negatively correlated with the development of a paraclade in the leaf axil. The thickened stems contain extra cell layers, arranged in rings, indicating that they may result from a cambium-like meristem. These results suggest that the REVOLUTA gene has a role in regulating the relative growth of apical and non-apical meristems in Arabidopsis.
Tenckhoff catheter placement: surgical aspects. (1985)

A 3-year retrospective review of 110 consecutive Tenckhoff catheter placements was undertaken. Major complications were found in 3.6 per cent of cases and minor complications occurred in 30 per cent. Analysis of cases in which catheters failed revealed that obesity and prior abdominal surgery occurred in 75 per cent of these patients. Attention to these factors and the use of appropriate techniques of placement and, in special situations, the use of endoscopy and fluoroscopy have reduced the failure rate of these high-risk situations. Management of infective complications are outlined and should include continued antibiotic dialysis and catheter replacement only if persistent peritonitis or fungal peritonitis occur. With these guidelines, improved peritoneal dialysis can be undertaken with less morbidity to the patient.
