Electrical and optical characterization of Er-implanted Si: The role of impurities and defects (1993)

The electrical and optical properties of Er-implanted Si are shown to be critically dependent on the presence of impurities and defects. A large enhancement in the electrical activation of Er (up to three orders of magnitude) is obtained by coimplanting Er with O or C at 300 °C. The use of C also allows one to obtain a good quality crystal after implantation and annealing. This is shown to be crucial in the photoluminescence process. In fact, in spite of the large amount of active Er atoms, photoluminescence is inhibited in the presence of the high concentration of precipitates and crystallographic defects which are left after annealing of the Er and O coimplants. The photoluminescence intensity is, on the other hand, enhanced by the high concentration of active Er atoms in the defect-free crystal which is left after annealing of the Er and C coimplants. Moreover, a clear shift in the main photoluminescence peaks is observed in Er- and C-coimplanted samples as a result of the different surroundings experienced by the Er atoms.
Diffuse Subcutaneous Fat Involvement in a Marginal Zone Lymphoma (2016)

Marginal zone lymphoma (MZL) is usually considered not avid for FDG. We report a case of a 57-year-old man with an MZL suspected for transformation. FDG-PET/CT showed a diffuse atypical involvement of subcutaneous fat, without sign suggestive for a transformation. No cutaneous involvement was clinically evident. A random subcutaneous biopsy was performed and showed the presence of MZL.
Extending SDARTS (2002)

SDARTS is a protocol and toolkit designed to facilitate metasearching. SDARTS combines two complementary existing protocols, SDLIP and STARTS, to define a uniform interface that collections should support for searching and exporting metasearch-related metadata. SDARTS also includes a toolkit with wrappers that are easily customized to make both local and remote document collections SDARTS-compliant. This paper describes two significant ways in which we have extended the SDARTS toolkit. First, we have added a tool that automatically builds rich content summaries for remote web collections bym probing the collections with appropriate queries. These content summaries can then be used by a metasearcher to select over which collections to evaluate a given query. Second, we have enhanced the SDARTS toolkit so that all SDARTS-compliant collections export their metadata under the emerging Open Archives Initiative (OAI) protocol. Conversely, the SDARTS toolkit now also allows all OAI-compliant collections to be made SDARTS-compliant with minimal effort. As a result, we implemented a bridge between SDARTS and OAI, which will facilitate easy interoperability among a potentially large number of collections. The SDARTS toolkit, with all related documentation and source code, is publicly available at http://sdarts.cs.columbia.edu.
State of Art in Realistic Head Modeling for Electro-magnetic Source Imaging of the Human Brain (1998)

Electric currents produced by the neural activity in the brain create electric potentials on the scalp and magnetic field distribution outside the scalp. Measuring electric and magnetic fields provides a means to understand the spatio-temporal distribution of the neural activity. The representations of the intracellular electric current of active cell populations based on bimodal data are called electro-magnetic source image (EMSI). With the recent development of large arrays of magnetic sensors, and systems for measuring scalp voltages at more than 100 locations, it is now feasible to implement computational methods that employ numerical models which incorporate the correct geometry and electrical properties of the head. This paper introduces the problem of developing realistic head models for generating more accurate EMSIs. In that sense it has a major review component. Tissue classification from magnetic resonance images forms the first step for realistic head modeling. Thus existing segmentation algorithms and their performances will be discussed. Next, two numerical methods, namely the Finite Element Method (FEM) and the Boundary Element Method (BEM), will be introduced for the solution of electric potential and magnetic fields for a known source configuration. An overall measure, relative difference measure (RDM) is used to measure the performance of the numerical models implemented using isoparametric, quadratic elements. It is observed that both FEM and BEM models yield RDMs around 1%. Finally, a methodology is introduced for parallel implementation of FEM. The implemented parallelization algorithm provided a speed-up of 1.49 on two processors, for a 31769 noded mesh.

All Optical Switch based on Nonlinear Directional Coupler with Saturable Absorber (2007)

All-optical switch based on nonlinear coupler with saturable absorber is proposed. FDTD simulation shows that this compact (15μm) device is capable of low-power (14μW), highspeed (100GHz) switching with 10-100× switching gain using realistic semiconductor materials.
Sialylated O-glycans and L-selectin sequentially mediate myeloid cell rolling in vivo (1995)

Leukocyte rolling precedes firm adhesion and emigration in inflammatory cell recruitment. Both P-selectin, an endothelial lectin that binds to sialylated O-glycans containing sialyl-Lewisx (sLex) on the granulocyte surface, and leukocyte L-selectin have been shown to mediate leukocyte rolling in vivo. Here, we investigate rolling of isolated human neutrophils (PMN), HL-60 promyelocytes, and an L-selectin-transfected cell line (300.19-L) during trauma-induced inflammation in rat mesenteric venules. HL-60 cells, which express no L-selectin but abundant sLex, rolled effectively immediately after abdominal surgery. HL-60 cell rolling was almost completely abolished by pretreatment with sialidase or monoclonal antibody (MoAb) AM-3 recognizing sLex, and was reduced by about 80% by O-sialoglycoprotein-endopeptidase (OSGP). By contrast, 300.19-L cells rolled poorly immediately after surgery but rolled well between 40 and 120 minutes after surgery. Their rolling was completely inhibited by the blocking L-selectin MoAb LAM1-3, but not by a binding control MoAb. PMN express both L-selectin and clustered, sialylated glycoproteins including P-selectin glycoprotein ligand-1 (PSGL-1). PMN showed effective rolling at all times, which was abolished by sialidase or MoAb AM-3 pretreatment during the first 30 minutes after surgery, but not later, when PMN rolling was largely L-selectin-dependent. We conclude that in trauma-induced inflammation, a two-step mechanism accounts for most of myeloid cell rolling, which initially requires O-glycans and subsequently depends on L-selectin function.
Platinum/taxane‐based chemotherapy with or without radiation therapy favorably impacts survival outcomes in stage I uterine papillary serous carcinoma (2009)

Stage I UPSC patients have significant risk for extrapelvic recurrence and poor survival. Recurrence and survival outcomes are improved in well-staged patients treated with platinum/taxane-based chemotherapy. This multi-institutional study is the largest to support systemic therapy for early stage UPSC patients.
Hevea Linamarase—A Nonspecific β-Glycosidase (1987)

In the leaf tissue of the cyanogenic plant Heyea brasiliensis, which contains large amounts of linamarin, there is no specific linamarse. In Hevea leaves only one ,B-glucosidase is detectable. It is responsible for the cleavage of all 6-glucosides and -galactosides occurring in Hevea leaf tissue, including the cyanogenic glucoside linamarin. Therefore, the enzyme is referred to as a j%glycosidase instead of the term @-glucosidase.
Surface Area Measurement of Powders by Adsorption in Liquid Phase. (I) : Calculation of Specific Surface Area of Calcium Carbonate Powders from the Adsorption of Stearic Acid (1955)

The measurement of specific surface area for various kinds of calcium carbonate powder by the adsorption of stearic acid in benzene solution has been investigated.The shape of the adsorption isotherms showed the S-type and was quite similar to the adsorption isotherms for gas phase at low temperature, and adsorption state on powder surface was unchanged irrespective of particle size and shape.For these isotherms, the 13 E T plot was linear and the V,,, the value of monolayer adsorption, was obtained from the intersect and the inclination of these straight lines.The value of V. calculated by the B E T equation agreed with the end of horizontal part of adsorption isotherms and, moreover, agreed with the value of monolayer adsorption from the change in surface pressure of the powder-liquid interface caused by the adsorption of stearic acid calculated by using Gibbs equation.
Chemical Composition and Nutritional Quality of Sugar Cookies Containing Full‐Fat Sweet Lupine Flour ( L. albus cv Multolupa ) (1986)

ABSTRACT Full‐fat sweet lupine flour (FFSL) ( Lupinus albus cv Multolupa) containing 35.4% protein was used to enrich the cookies given to a group of school children. FFSL replaced 5, 10, 15, 20, and 25% of wheat flour in the formula. Farinological study, physical dough properties, chemical composition, and nutritional quality of cookies were studied. The protein content of the cookies increased by 8.9% up to 55.7% for the 5% and 25% FFSL, respectively. The highest PER (1.92) was found in cookies with 20% FFSL compared with 0.15 for the control. The results show a new area for application of FFSL in human diets.
Post-traumatic heterotopic ossification of the crus. A case study. (2011)

The formation of mature lamellar bone at an ectopic site in the body is called heterotopic ossification. We report the case of a 28 year-old patient with heterotopic ossification (HO) in the left crus. He complained of difficulties with walking and limited ROM of the ankle joint. At surgery, an incision was made through the center of the HO focus, which was palpable. No change in ROM of the ankle joint was observed following HO removal. The decision was made to lengthen the Achilles tendon. After the lengthening of the Achilles tendon, the ROM of the ankle joint was increased. Lengthening of the Achilles tendon following the removal of posttraumatic HO in the crus is a safe and effective procedure; if the ROM of the ankle joint is restricted.
Thermal solutions to Pentium processors in TCP in notebooks and sub-notebooks (1996)

In this paper, we will review the various thermal enhancements from the component, board, and system level for the use of the Pentium processor in tape carrier package (TCP) in notebooks and sub-notebooks. The thermal tests were conducted in one reference notebook and sub-notebook using test boards and thermal test dies. With the assumption of a maximum junction temperature of 100/spl deg/C and an outside ambient temperature of 35/spl deg/C, thermal characterizations of TCP found that with 4 W of board power, TCP can dissipate up to 3.55 W of CPU power in the reference notebook and 2.72 W in the reference sub-notebook. Various thermal enhancements such as venting holes, metal plates, and heat sinks were evaluated in the reference notebook. For the design target of 6.5 W of CPU power with 4 W of board power, four thermal solutions were proposed for the reference notebook: The heat sink and aluminum plate solution, heat pipe connected to the keyboard solution, heat pipe connected to outside aluminum plate solution, and fan/heat sink solution. Two solutions were proposed for the reference sub-notebook: The heat pipe connected to keyboard solution and heat pipe on the bottom chassis solution. Although the study was conducted in the reference notebook and sub-notebook, the thermal design trade offs and relative cooling capabilities are applicable to the general notebook and sub-notebook thermal designs.

Disposition of amsacrine and its analogue 9-([2-methoxy-4-[(methylsulfonyl)amino]phenyl]amino)-N,5-dimethyl-4- acridinecarboxamide (CI-921) in plasma, liver, and Lewis lung tumors in mice. (1990)

9-([2-Methoxy-4-[(methylsulfonyl)amino]phenyl]amino)-N,5-dimethyl-4- acridinecarboxamide (CI-921), an analogue of the clinical antileukemia drug amsacrine with improved solid tumor activity in mice, is currently being evaluated in patients. In order to determine whether CI-921 possesses any advantages over amsacrine in terms of tissue delivery, the pharmacokinetics of amsacrine and CI-921 were determined following i.v. injection in male B6D2F1 mice. Plasma kinetics in normal mice were measured following administration of 14.4, 28.9, and 57.7 mumol/kg. The kinetics in s.c. Lewis lung tumors, and in plasma and livers of normal and tumor-bearing mice were measured following administration of 57.7 mumol/kg. CI-921 and amsacrine were quantitated by high-performance liquid chromatography after extraction from plasma and from liver and tumor homogenates. In experiments with appropriate 3H-labeled compounds, both total and covalently bound radioactivity (determined after precipitation and washing with acetonitrile) were measured in plasma and in liver homogenates. Over this dose range, nonlinear kinetics were observed in plasma for unchanged CI-921 and amsacrine, and a reasonable fit was obtained with Michaelis-Menten kinetics to a one-compartment model for CI-921 (Km 3.7 mumol/liter; Vmax 18 mumol/h/kg; V ss 3.3 liter/kg) and a two-compartment model for amsacrine (Km 3.6 mumol/liter; Vmax 76 mumol/h/kg; Vss 4.8 liter/kg). The area under the concentration-time curve (AUC) for plasma following a dose of 57.7 mumol/kg was 31 mumol.h/liter for CI-921 and 6.3 mumol.h/liter for amsacrine. However, equilibrium dialysis measurements indicated high plasma protein binding with free drug fractions for CI-921 and amsacrine of 0.63 and 6.7%, respectively. In the liver, unchanged drug concentrations and total radioactivity for both compounds were approximately 10-fold those in plasma, and the tissue half-life of CI-921 was approximately 4-fold longer for CI-921 than for amsacrine. Plasma and liver kinetics in mice with s.c. Lewis lung tumors were similar to those in normal mice. Tumor half-lives of unchanged CI-921 and amsacrine were 3.9 and 2.7 h, respectively, considerably longer than those for plasma (1.2 and 0.30 h respectively) or liver (1.2 and 0.28 h, respectively). Tumor AUC values for CI-921 and amsacrine were 68 and 37 mumol.h/liter, respectively, as compared to the calculated AUC values for free drug in plasma of 0.19 and 0.42 mumol.h/liter, respectively. It is concluded that the uptake into tumors from the plasma free drug fraction is more efficient for CI-921 than for amsacrine.
Collaboration in supply chains for development of CPS enabled by semantic web technologies (2018)

The development of Industrial Cyber-Physical Systems (ICPS) requires new ways of collaboration between ICPS vendors and companies which provide them with parts and components. As ICPS extend existing systems, e.g. machines or healthcare equipment, by electronic components, new supply chains will evolve between companies which were not connected before. Hence, traditional methods for collaboration will not fit for them anymore. We propose a new approach for collaborations in ICPS development. It relies on technologies from the Semantic Web and consists of a web platform where ICPS vendors and vendors of electrical, electronical, information and communication technology components can virtually meet. Component vendors can describe their products, ICPS element vendors their product ideas and requirements. To match requirements and offers, semantic descriptions of both are necessary. Then, matching of requirements and offers will be realized by semantic reasoners. They have to find RDF graph chains which link requirement and offer descriptions.
Toll-like receptor 4 (TLR4) and interferon-gamma (IFN-r) are required for HMGB1-induced TNF release from macrophages. (34.18) (2010)

Abstract High mobility group box 1 (HMGB1) has been implicated as a cytokine mediator in the pathogenesis of inflammatory diseases (Yang et al. BBA, 2009). To study mechanisms of HMGB1 action, we produced mammalian HMGB1, devoid of bacterial products, and examined receptor signaling for HMGB1 mediated macrophage cytokine release. HMGB1 induced significant TNF release in macrophages from TLR2 KO, RAGE KO and wild type (WT) mice (n = 4-5 experiments). HMGB1 induced TNF release was completely abolished in TLR4 KO macrophages as compared to WT. Interestingly, we observed that HMGB1 induced TNF mRNA expression, but not TNF protein release, from TLR4 KO mouse macrophages. Pre-treatment of TLR4 KO macrophages with IFN-r restored HMGB1-induced TNF protein release. Thus, our results indicate that TLR4 is required for HMGB1-mediated cytokine release from macrophages, and that IFN-r can restore HMGB1-induced TNF release in TLR4 KO macrophages.

Synthesis, ribosomal selectivity, and antibacterial activity of netilmicin 4′-derivatives (2019)

Halogenation of a suitably protected netilmicin derivative enables preparation of 4'-chloro-, bromo-, and iodo derivatives of netilmicin after deprotection. Suzuki coupling of a protected 4'-bromo derivative with phenylboronic acid or butyltrifluoroborate affords the corresponding 4'-phenyl and 4'-butyl derivatives of netilmicin. Sulfenylation of suitably protected netilmicin derivative with ethanesulfenyl chloride followed by deprotection affords 4'-ethylsulfanylnetilmicin. All netilmicin 4'-derivatives displayed reduced levels of inhibition for prokaryotic ribosomes and reduced antibacterial activity against typical Gram-positive and Gram-negative strains. None of the derivatives displayed enhanced target selectivity.
Multivariate speech activity dector based on the syllable rate (1998)

Computationally efficient algorithms which perform speech activity detection have significant potential economic and labor saving benefit, by automating an extremely tedious manual process. In many applications, it is desirable to extract intervals of speech which are obtained by segments of other signal types. In the past, algorithms which successfully discriminate between speech and one specific other signal type have been developed. Frequently, these algorithms fail when the specific non-speech signal is replaced by a different non-speech discrimination problem. Typically, several signal specific discriminators are blindly combined with predictable negative results. Moreover, when a large number of discriminators are involved, dimensions reduction is achieved using Principal Components, which optimally compresses signal variance into the fewest number of dimensions. Unfortunately, these new coordinates are not necessarily optimal for discrimination. In this paper we apply graphical tools to determine a set of discriminators which produce excellent speech vs. non-clustering, thereby eliminating the guesswork in selecting good feature vectors. This cluster structure provides a basis for a general multivariate speech vs. non-speech discriminator, which compares very favorably with the TALKATIVE speech extraction algorithm.
Effects of the incorporation of CHAPS into SDS micelles on neuropeptide-micelle binding: Separation of the role of electrostatic interactions from hydrophobic interactions (2001)

It is well known that neuropeptides interact with lipid vesicles in a manner similar to biological membranes, with electrostatic interactions between the two providing a mechanism for concentrating the peptide at the vesicle's surface, followed by hydrophobic interactions between the peptide and the core of the vesicle that induce and stabilize secondary structure motifs. In an effort to understand these interactions to a greater extent, our group has developed a series of anionic micelles (SDS) containing various concentrations of the bile salt CHAPS, which is used as a model for cholesterol. The incorporation of CHAPS into the hydrophobic core of these micelles should alter the degree to which the neuropeptide can insert itself, affecting structure. These interactions were investigated using two-dimensional NMR, pulse-field gradient (PFG) NMR, and molecular modeling experiments. The results of this study clearly indicate that electrostatic and hydrophobic interactions between the micelle and neuropeptide are completely independent of one another. Increasing the concentration of CHAPS to 15 mM in the micelles blocks the insertion of the hydrophobic side chains of the neuropeptide into the hydrophobic core of the micelles. The electrostatic interactions as determined by diffusion measurements are not affected by the presence of increasing CHAPS concentration. Our observations are consistent with the predictions of Seelig (A. Seelig and J. Seelig, "Interaction of Drugs and Peptides with the Lipid Membrane," in Structure and Function of 7TM Receptors, T. W. Schwartz, S. A. Hjorth, and T. S. Kastrup, Eds., Munksgaard: Location, 1996).
Evolution to Acute Myeloblastic Leukemia from Chronic Neutrophilic Leukemia with Dysplastic Features in Granulocytic Lineage (2000)

We experienced the case of an 82-year-old man with chronic neutrophilic leukemia (CNL) with dysplastic features in the granulocytic lineage which subsequently progressed to acute myeloblastic leukemia (AML) with myelofibrosis. The patient had hepatosplenomegaly, but there was no evident cause of neutrophilic leukocytosis. The cytogenetic study showed that he had a normal karyotype. Concentrations of the serum granulocyte colony-stimulating factor (G-CSF) were not detectable. Two years after the diagnosis of CNL, blastic transformation to AML occurred with myelofibrosis and significant morphological abnormalities in neutrophils. The blasts were positive for myeloperoxidase, CD33, CD34, and HLA-DR, and the presence of dysplasia within the granulocytic lineage suggested that he had an abnormality at the level of the granulocyte-committed progenitors. Heterogeneous origins of CNL might lead to various clinicopathological features in each case.
