Experimental and clinical studies with radiofrequency-induced thermal endometrial ablation for functional menorrhagia (1990)

A method of ablating the endometrium has been introduced into clinical practice that uses radiofrequency electromagnetic energy to heat the endometrium, using a probe inserted through the cervix. Preliminary studies suggest that over 80% of patients treated will develop either amenorrhea or a significant reduction in flow. The advantages of radiofrequency endometrial ablation over laser ablation or resection are the avoidance of intravascular fluid absorption, simplicity (no special operative hysteroscopic skills are required), speed of operation, and reduced cost compared with the Nd:YAG laser. In this paper, we describe the experimental studies performed during development of this new technique.

IMPROVED CARDIAC ALLOGRAFT FUNCTION FOLLOWING TRIIODOTHYRONINE THERAPY TO BOTH DONOR AND RECIPIENT (1990)

Brain death is associated with neuroendocrine changes, in particular with a significant reduction of plasma-free triiodothyronine (T3) that results in impaired aerobic metabolism. Myocardial energy stores are reduced and tissue lactate increased. Cardiac function deteriorates. Similar metabolic changes are seen in patients undergoing open-heart surgery on cardiopulmonary bypass, including those undergoing heart transplantation. Therapy with T3 leads to a reversal of these metabolic changes, resulting in improved cardiac function. One hundred and sixteen consecutive potential donors have been so treated, as have 70 of the recipients. Immediate posttransplant cardiac function was good in all but 3, and these hearts recovered to normal within a maximum of 24 hr of mechanical support. In 2 small randomized trials in patients undergoing myocardial revascularization on cardiopulmonary bypass, postoperative T3 therapy was associated with a reduced need for inotropic support and diuretic therapy in the first study and improved cardiac output in the second study.

Improvements in MWD Telemetry: "The Right Data at the Right Time" (1993)

Abstract The 1991 SPE Forum on MWD concluded that current telemetry data rate via mud pulse was inadequate. This paper addresses this issue. New downhole sensors have been continuously added to MWD Systems and have joined the directional measurements and simple formation evaluation tools commercialized in the seventies. As a result, MWD Systems have been challenged to transmit an increasing amount of data to the surface. Most commercial Systems use the mud column as the transmission channel. MWD telemetry is revisited, analyzing in detail the factors affecting the transmission through the mud. Noise sources and new techniques to minimize interference are described and field examples are presented. The maximum data rate achievable through the mud channel is evaluated, and is compared with current and future needs for real-time use. Data compression techniques are discussed. The impact of data rates on log quality, for a given drilling rate of penetration, is illustrated through field examples at different data rates. New techniques of quality checks on the data which allow quantification of the accuracy of the transmission are described with Statistical test results. Examples of current MWD telemetry Systems covering the range of data rates available today (from 0.5 bits/s to more than 5 bits/s) are presented. The use of microprocessors in the new generation of MWD tools is shown to have impacted dramatically the reliability of the transmission, both in quality and versatility with direct benefits to the end user of the data.
Zeolite Synthesis Using Hierarchical Structure-Directing Surfactants: Retaining Porous Structure of Initial Synthesis Gel and Precursors (2012)

Zeolite beta with a mesopore-micropore hierarchy is hydrothermally synthesized here using various surfactants that can function as a hierarchical structure-directing agent at both the meso- and microstructural levels. Tetraethoxysilane and diatomaceous earth were tested as the silica sources. The pore size distribution of the zeolite was analyzed by N2 adsorption and electron microscopy. The result was related to the surfactant structure, silica source, and Na+ concentration. The zeolite showed quite uniform mesopores corresponding to the surfactant micelles, in addition to zeolitic micropores generated by the surfactant head groups. Furthermore, an additional level of large pores (≥20 nm) could be obtained as a result of the retaining of pores from the initial synthesis gel or the zeolite precursor. The large pores were fully retained when the silica source was transformed into a crystalline zeolite via pseudomorphic transformation without migration into the solution phase. The transformation could be controlled by the choice of the synthesis conditions and surfactants. The resultant zeolite with a macropore-mesopore-micropore hierarchy shows potential applicability where facile diffusion is required.
Flow cytometric analysis of the nuclear DNA content of hepatoblastoma (1991)

The nuclear DNA content of 15 hepatoblastoma cases was determined in paraffin-embedded tissues by flow cytometry. The DNA index (DI) was calculated, and the ploidy pattern of nuclear DNA was estimated. The correlation between the ploidy pattern and clinicopathologic findings was studied, and the prognostic significance of the ploidy pattern was investigated. An aneuploid pattern was seen in 50% of the lesions with histologic embryonal and anaplastic types. It was not seen in the fetal type. In the tumors with combined epithelial components, the fetal-type component had a diploid pattern in all five cases. The embryonal-type component was associated with aneuploidy in two of five cases. In aneuploid tumors, vascular invasion (tumor emboli in the vessels) was observed more frequently. The prognosis of the patients with an aneuploid tumor was significantly poorer. These results indicate that nuclear DNA ploidy pattern analysis might be useful in investigating the prognosis of hepatoblastoma.
A Si-Doped High-Performance WOx Resistance Memory Using a Novel Field-Enhanced Structure (2016)

We developed a simple structure that can enhance the local electric field thus reduce the forming and SET/RESET operation voltage for WOx ReRAM. Si-doped W film is used to further increase the initial resistance and improve the reliability properties. TCAD simulation shows that the field enhanced structure provides an equivalent electrical field that would only be achieved by very small conventional W plug ~ 10nm in size. Thus our novel but simple structure can provide the benefit of deep scaled device without expensive advanced lithography, and with better performance and reliability of larger devices. Furthermore,Si-doping provides an additional knob that allows resistance tuning to optimize the cell and array performance. The 1T1R memory array is well controlled and MLC operation can be reliably achieved by constant current RESET with logic states determined by cumulative RESET pulse duration.
A novel compact PMSM with magnetic bearing for artificial heart application (2000)

This paper describes a novel compact permanent-magnet synchronous motor with a configuration of axial-field slotted windings. It is designed for driving an artificial heart. Both the motor rotor and the pump impeller of the artificial heart are levitated by a magnetic bearing. Structure description, design considerations, and analyses for the motor and bearing are presented in this paper.
Sexual and Gender-Based Violence : What is the World Bank Doing and What Have We Learned, A Strategic Review (2013)

Sexual and gender-based violence (SGBV) is the most egregious manifestation of gender inequality. The impacts of such violence extend far beyond the individual survivors, affecting households, communities, and spanning across generations. SGBV is now widely recognized as a development constraint that falls within the World Bank's mandate. The majority of the Bank's work on SGBV consists of analytical work, supported by trust funds, geographically focused in contexts with particularly intense reports of SGBV, and focused on responding to the problem rather than on prevention. This review identified 38 World Bank operations active in 2008 or later, that either had an explicit focus on SGBV or components on this topic, for an estimated 22.5 million dollars in investment. Attention to SGBV is growing within the Bank portfolio and diversifying to new financial instruments. This report is an effort to take stock of the experience of the World Bank in addressing SGBV, from 2008 to 2013, in order to capture lessons for engaging more strategically on this issue across the Bank portfolio. This review took a mixed methods approach that triangulated data from the operations portal, an in-depth review of project documents, and structured interviews with task teams. The review covered projects that were active as of 2008, in an effort to keep the focus on current projects. It was recommended that the Bank is well-positioned to support integrated, multi-sectoral responses to SGBV in client countries. In order to achieve long-term reductions in violence, efforts to protect and serve the needs of survivors need to be balanced with interventions to change the overall social environment in which violence occurs.
Cycle-Efficient LFSR Implementation on Word-Based Microarchitecture (2012)

Cycle-efficient implementation of the linear feedback shift register (LFSR) algorithm on a word-based microarchitecture is investigated. This work examines an algorithm transformation method, called term-preserving look-ahead transformation (TePLAT), that transforms the bit-serial LFSR algorithm into a bit parallel format while maintaining the overhead of the original LFSR algorithm. Detailed implementation methodologies as well as extensive simulation results are presented. We apply TePLAT to 25 commonly used LFSRs and test the resulting parallel formulations on two popular word-based microprocessor development platforms: a Texas Instrument C6416 Code Composition Simulator and an ARM-9 Simulator. In all 25 cases, TePLAT transformed LFSR formulations consistently achieve much higher throughput than those of a naïve implementation and a traditional look-ahead transformation-based implementation.
Deflection of atoms by standing-wave radiation (1985)

We have observed momentum transfer from a standing-wave light field to an atomic beam. The atomic beam is split symmetrically into two peaks whose separation increases with field strength. The short interaction time ensures that this deflection is due to induced forces; these are described using a semiclassical dressed-atom treatment, which gives good agreement with the data. In addition to the splitting, we have observed diffraction of the atomic beam due to the exchange of even numbers of photons with the field.
Flt3 Ligand Bioactivity and Pharmacology in Neoplasia (2004)

Fms-like tyrosine kinase 3 ligand (Flt3L) has multiple effects on the hematopoietic and immune systems. Further, preclinical studies have suggested potential therapeutic activity against cancer. Flt3L is a potent hematopoietic cytokine, capable of stimulating the expansion and differentiation of hematopoietic progenitor and stem cells. Administration of Flt3L mobilizes hematopoietic cells from the bone marrow (BM) into the blood, lymphoid organs, and parenchymal tissues. This mobilization activity, especially effective in combination with granulocyte colony stimulating factor (G-CSF), has stimulated studies of Flt3L in hematopoietic stem cell (HSC) transplantation. In addition to its effects on hematopoietic stem and progenitor cells, Flt3L has been shown to increase the frequency and number of dendritic cells (DCs) within the circulatory system and solid organs. DC expansion by Flt3L has been the focus of preclinical and clinical studies on antigen (Ag) specific T-cell mediated immunity. The mechanism for the augmentation of T-cell mediated immunity has yet to be completely identified, although Flt3L's ability to expand DCs in lymphoid and non-lymphoid tissues is involved. This expansion occurs primarily with DCs, which secrete interleukin (IL) 12. Consistent with the expansion of this DC population, treatment with Flt3L enhances T-cell mitogenesis and preferentially induces type 1 T-cell responses. However, the DCs resulting from Flt3L administration are immature, leading in some studies to the induction of tolerance. This review focuses on the effects of Flt3L on DCs and other effector populations, and on its potential activity as a therapeutic agent for cancer, alone and in combination with vaccines.
2APL: a practical agent programming language (2008)

This article presents a BDI-based agent-oriented programming language, called 2APL (A Practical Agent Programming Language). This programming language facilitates the implementation of multi-agent systems consisting of individual agents that may share and access external environments. It realizes an effective integration of declarative and imperative style programming by introducing and integrating declarative beliefs and goals with events and plans. It also provides practical programming constructs to allow the generation, repair, and (different modes of) execution of plans based on beliefs, goals, and events. The formal syntax and semantics of the programming language are given and its relation with existing BDI-based agent-oriented programming languages is discussed.
Recombinant p21 Protein Inhibits Lymphocyte Proliferation and Transcription Factors (2005)

Cellular proliferation determines the events leading to the initiation and development of inflammation, immune activation, cancer, atherogenesis, and other disorders associated with aberrant cell proliferation. Cyclin inhibitor p21 plays a unique role in limiting cell cycle progression. However, its effectiveness can only be demonstrated with direct in vitro and in vivo delivery to control aberrant proliferation. We demonstrate that using a protein-transducing domain p21 protein a) localizes within the nuclear compartments of cells, b) interacts with transcription factors, NF-kappaB, and NFATs (NFATc and NFATp), and c) inhibits lymphocyte proliferation and expression of proinflammatory cytokines. This study using lymphocyte proliferation as a model suggests that the recombinant p21 protein can directly be delivered as a therapeutic protein to provide a novel, viable, and powerful strategy to limit proliferation, inflammation, alloimmune activation, cancer, and vascular proliferative disorders such as atherosclerosis.
Chimeric Proton-Pumping Rhodopsins Containing the Cytoplasmic Loop of Bovine Rhodopsin (2014)

G-protein-coupled receptors (GPCRs) transmit stimuli to intracellular signaling systems. Rhodopsin (Rh), which is a prototypical GPCR, possesses an 11-cis retinal. Photoisomerization of 11-cis to all-trans leads to structural changes in the protein of cytoplasmic loops, activating G-protein. Microbial rhodopsins are similar heptahelical membrane proteins that function as bacterial sensors, light-driven ion-pumps, or light-gated channels. They possess an all-trans retinal, and photoisomerization to 13-cis triggers structural changes in protein. Despite these similarities, there is no sequence homology between visual and microbial rhodopsins, and microbial rhodopsins do not activate G-proteins. In this study, new chimeric proton-pumping rhodopsins, proteorhodopsin (PR) and Gloeobacter rhodopsin (GR) were designed by replacing cytoplasmic loops with bovine Rh loops. Although G-protein was not activated by the PR chimeras, all 12 GR chimeras activated G-protein. The GR chimera containing the second cytoplasmic loop of bovine Rh did not activate G-protein. However, the chimera with a second and third double-loop further enhanced G-protein activation. Introduction of an E132Q mutation slowed the photocycle 30-fold and enhanced activation. The highest catalytic activity of the GR chimera was still 3,200 times lower than bovine Rh but only 64 times lower than amphioxus Go-rhodopsin. This GR chimera showed a strong absorption change of the amide-I band on a light-minus-dark difference FTIR spectrum which could represent a larger helical opening, important for G-protein activation. The light-dependent catalytic activity of this GR chimera makes it a potential optogenetic tool for enzymatic activation by light.
Formaldehyde-free tannin-based foams and their use as lightweight panels (2011)

100% natural tannin-based rigid foams were synthesized. Tannin-furfuryl alcohol networks were polymerized in an acid environment applying a temperature between 120° and 160°C. The process was developed in two ways: in a ventilated oven and in between the heated plates of a press. The foams produced showed a high homogeneity in both cases. By modifying the formulation in terms of type and amount of components it was possible to produce two kinds of foams: (1) light with density of approximately 50 Kg/m³, and (2) resistant having a density of approximately 180 Kg/m³. The compression resistance and the water absorption of these materials were evaluated. The results of these tests, in comparison with those of formaldehyde-reinforced tannin foams, indicated that these lightweight foams have lower mechanical strength but higher water affinity. The latter was also demonstrated with moisture uptake measurements. Particular attention was dedicated to the press-produced foams for their possible application as core-layer for lightweight composite panels.
Synthesis of <i>N</i> = 8 Armchair Graphene Nanoribbons from Four Distinct Polydiacetylenes (2017)

We demonstrate a highly efficient thermal conversion of four differently substituted polydiacetylenes (PDAs 1 and 2a-c) into virtually indistinguishable N = 8 armchair graphene nanoribbons ([8]<sub>A</sub>GNR). PDAs 1 and 2a-c are themselves easily accessed through photochemically initiated topochemical polymerization of diynes 3 and 4a-c in the crystal. The clean, quantitative transformation of PDAs 1 and 2a-c into [8]<sub>A</sub>GNR occurs via a series of Hopf pericyclic reactions, followed by aromatization reactions of the annulated polycyclic aromatic intermediates, as well as homolytic bond fragmentation of the edge functional groups upon heating up to 600 °C under an inert atmosphere. We characterize the different steps of both processes using complementary spectroscopic techniques (CP/MAS <sup>13</sup>C NMR, Raman, FT-IR, and XPS) and high-resolution transmission electron microscopy (HRTEM). This novel approach to GNRs exploits the power of crystal engineering and solid-state reactions by targeting very large organic structures through programmed chemical transformations. It also affords the first reported [8]<sub>A</sub>GNR, which can now be synthesized on a large scale via two operationally simple and discrete solid-state processes.
Any open bounded subset of R <i> <sup>n</sup> </i> has the same homotopy type than its medial axis (2003)

Medial Axis Transform is sometimes used as an intermediate representation in algorithms for meshing or recognition of shapes from digitized data. This raises the question whether the Medial Axis captures fundamental topological invariants of the object. The (positive) answer has been known already in the case of smooth objects. The main result presented here is the homotopy equivalence of any bounded open subset of Rn with its Medial Axis.
