Thermal conductivity and mechanical properties of aluminum nitride filled linear low‐density polyethylene composites (2009)

Abstract To acquire polymer composites with high thermal conductivity and mechanical properties, the aluminum nitride (AlN) microparticles modified with titanate coupling reagent of isopropyltrioleictitanate (NDZ‐105) were employed to blend linear low‐density polyethylene (LLDPE) via powder mixing method. Thermal conductive coefficient of the AlN/LLDPE composites was measured using hot disk thermal analyzer, and the thermal stability characteristics of AlN/LLDPE composites were mainly investigated via thermogravimetric analyzer (TGA) and differential scanning calorimeter (DSC). The results indicated that the use of AlN particles modified by NDZ‐105 significantly enhanced thermal conductivity and mechanical properties of AlN/LLDPE composites. The thermal conductivity coefficient λ was 1.0842 W/mk with 30% volume fraction of AlN, about three times higher than that of native LLDPE. The tensile strength of composites was maximum (17.42 MPa) with 20% mass fraction of AlN. DSC analyses results indicated that AlN had an influence on the melting temperature and the crystallinity of LLDPE. Additionally, TGA analyses showed that the thermal stability of LLDPE was significantly increased with addition of AlN. POLYM. ENG. SCI., 2009. © 2009 Society of Plastics Engineers
Cyclic fed‐batch culture for production of human serum albumin in <i>Pichia pastoris</i> (2003)

Simple cyclic fed-batch culture (cfbc), consisting of a constant medium feed with periodic withdrawals of culture, resulted in a product yield (13.4 mg protein per gram biomass) similar to that obtained using the complex multiphase industrial production strategy (13.7 mg protein per gram biomass). In cfbc, productivity was ultimately limited by the rate at which the cells could assimilate methanol. Glycerol was inhibitory to growth at high concentrations. However, product yield continued to increase as the glycerol concentration was increased. In chemostat culture, dissolved oxygen concentration influenced product yield independently of any detectable influence on cell growth.

[<sup>125</sup>I]‐PD 151242: a selective radioligand for human ET<sub>A</sub> receptors (1994)

Our aim was to synthesize a new endothelin ETA selective radioligand, [125I]-PD151242 and characterize the compound in human vascular tissue. Binding of [125I]-PD151242 to sections of human aorta was time-dependent and reached equilibrium after 120 min at 23 degrees C with an association rate constant of 1.26 +/- 0.17 x 10(8) M-1 min-1 (n = 3 individuals +/- s.e.mean). The binding was reversible at 23 degrees C with an observed dissociation rate constant of 0.0025 +/- 0.0006 min-1 (n = 3). Saturation binding assays using [125I]-PD151242 revealed a single population of high affinity ET receptors (n = 3) in aorta (KD = 0.76 +/- 0.17 nM; Bmax = 5.98 +/- 1.56 fmol mg-1 protein), pulmonary (KD = 1.75 +/- 0.20 nM; Bmax = 12.78 +/- 1.39 fmol mg-1 protein) and coronary arteries (KD = 0.51 +/- 0.07 nM; Bmax = 44.9 +/- 1.67 fmol mg-1 protein). ETA selective ligands competed for [125I]-PD151242 binding in aorta with nanomolar affinity (BQ123, KD = 0.41 +/- 0.26 nM; FR139317, KD = 0.55 +/- 0.11 nM) whereas the ETB selective compound, BQ3020, competed with micromolar affinity (KD = 1.36 +/- 0.25 microM). In isolated coronary arteries, PD151242 was a functional antagonist and caused a significant, parallel rightward shift of the ET-1 dose-response curve with a pA2 value of 5.92 (n = 5) and a slope of unity. The high affinity and selectivity of [125I]-PD151242 for ETA receptors will facilitate the characterization of this sub-type in human tissues.
Reincarnation Revisited. Question format and the distribution of belief in reincarnation in survey research (2013)

Comparing frequency of belief in reincarnation from different international survey projects (RAMP, EVS, ISSP) reveals differences of about 15 to 20 percent depending on the specific question format. If single binary questions are used, then belief in reincarnation is more often reported than if a forced-choice question is used which offers respondents alternatives to belief in reincarnation (e.g. resurrection). One possible explanation for this result is that respondents confuse reincarnation and resurrection if a binary item is used. If this is true, then empirical studies on religious individualization would be flawed because they use belief in reincarnation as an indicator for holistic beliefs such as New Age spirituality, post-Christian spirituality and subjective life spirituality.\nUsing a two stage question on beliefs about the afterlife that combines a binary rating procedure (1. stage) with a reduced forced-choice design (2. stage) allows analysis of whether respondents systematically confuse reincarnation and resurrection. Moreover, analysing associations with other variables on religious beliefs allows testing if consistent patterns of belief emerge.\nThe data provide little evidence that respondents confuse resurrection and reincarnation. Rather, they reveal a high level of uncertainty about belief in the afterlife. To conclude, the paper suggests some recommendations on how belief in reincarnation should be used as an indicator for holistic beliefs.
Mitigation of Insider Risks Using Distributed Agent Detection, Filtering, and Signaling (2006)

An insider-robust approach to file integrity verification is developed using interacting strata of mobile agents. Previous approaches relied upon monolithic architectures, or more recently, agent frameworks using a centralized control mechanism or common reporting repository. However, any such distinct tampering-point introduces vulnerabilities, especially from knowledgeable insiders capable of abusing security-critical resources. In the Collaborative Object Notification Framework for Insider Defense using Autonomous Network Transactions (CONFIDANT), the mechanisms for tampering detection, decision-making, and alert signaling are distributed and corroborated by autonomous agents. In this paper, the CONFIDANT file integrity verification framework is presented focusing on insider defense aspects. User capability classes are defined and critical physical tampering points in intrusion detection architectures are identified. CONFIDANT mitigation techniques of insider tampering exposures and example scenarios are presented.
Design of a Catalytic Combustor for Heavy-Duty Gas Turbines (1983)

Laboratory tests of catalytic combustors with distillate fuel have achieved ultralow NOx formation at catalytic reactor exit temperatures and combustion efficiencies consistent with state-of-the-art gas turbine requirements. Concomitant with these features, however, are design limitations such as narrow turn-down range and unique reactor mounting requirements. This paper presents fully analyzed conceptual design solutions to these problems within the constraints of fixed geometry, full catalytic combustion over 80 percent of the turbine load range, and retrofit to an existing gas turbine. The combustor design incorporates (a) a gutter stabilized pilot burner downstream of the reactor for operation from ignition to full-speed no-load, (b) a segmented fuel-air preparation system for fuel staging of the reactor, (c) a reactor mounting system which accommodates thermal growth and start-up and shutdown transients, and (d) a graded cell reactor. These features were achieved while maintaining low reactor face velocities and system pressure drops.
Selective metal parallel shunting inductor and its VCO application (2005)

The methodology to calculate the parasitic capacitances in differential symmetric inductors will be presented in this paper. Inspired by the proposed methodology, a method called selective metal parallel shunting (SMPS) can move f/sub Qmax/ onto the desired frequency without additional processing steps. Based on the proposed methodology, a customized program is developed to predict Q/sub max/s and f/sub Qmax/s of on-chip inductors. Differential symmetric inductors and spiral ones with planar, all metal parallel shunting (AMPS), and SMPS configurations have been implemented in a 1P4M 0.35-/spl mu/m CMOS process to verify the proposed method. Moreover, three 2.3-2.4 GHz voltage-controlled oscillators (VCOs) using planar, AMPS, and SMPS inductors, have also been realized. The phase noise of the VCO using SMPS inductors can be improved by 9.3 and 6 dB at 100-kHz offset frequency, respectively, compared to the VCOs using planar and AMPS inductors. The proposed SMPS technique can not only be applicable to VCO but also other RF circuits.
BASIS OF STABILITY OF AMINE SALTS OF LINOLEIC ACID (1971)

SUMMARY— The mechanism and generality of the known stabilization against autoxidation conferred on linoleic acid by certain basic amino acids, such as lysine and arginine, was investigated. Basic amino acids were the only class of compounds found to confer the effect. However, the smallest basic amino acid, 2,3‐diaminopropionic acid, was not effective, nor was αβω‐diaminc acid, 3,6‐diaminohexanoic acid, although a simple isomer of lysine. The stabilization was observed only in the solid phase. Inclusion of sodium chloride in the solid matrix was deleterious to the effect. A large number of physical and chemical observations were made and correlated but it has not been possible to draw detailed conclusions about the mechanism of stabilization, nor can a detailed structure of the stabilized complex be suggested. The cause of the phenomenon appears to be closely associated with the physical arrangement of the ions in the crystal lattice.
Technique to produce coherent x-ray radiation via laser pumping of a relativistic ion beam (1986)

The level population of a beam of relativistic positive ions with Z≥2 having a single bound electron may be inverted by the application of a ‘‘π pulse’’ of laser radiation tuned to the Doppler-shifted 1s–2p transition. When the laser beam and ion beam move in opposite directions, the required laser frequency is reduced by a factor 2γ. Subsequently applied short wavelength resonant radiation moving in the same direction as the ion beam (with an inverted population) will be amplified via stimulated emission, the wavelength in the lab frame now being shorter than the original laser wavelength by a factor (2γ)2.
Kaposi's Sarcoma-Associated Herpesvirus K3 Utilizes the Ubiquitin-Proteasome System in Routing Class I Major Histocompatibility Complexes to Late Endocytic Compartments (2002)

Human herpesvirus 8 (HHV8) downregulates major histocompatibility complex (MHC) class I complexes from the plasma membrane via two of its genes, K3 and K5. The N termini of K3 and K5 contain a plant homeodomain (PHD) predicted to be structurally similar to RING domains found in E3 ubiquitin ligases. In view of the importance of the ubiquitin-proteasome system in sorting within the endocytic pathway, we analyzed its role in downregulation of MHC class I complexes in cells expressing K3. Proteasome inhibitors as well as cysteine and aspartyl protease inhibitors stabilize MHC class I complexes in cells expressing K3. However, proteasome inhibitors differentially affect sorting of MHC class I complexes within the endocytic pathway and prevent their delivery to a dense endosomal compartment. In this compartment, the cytoplasmic tail of MHC class I complexes is cleaved by cysteine proteases. The complex is then cleaved within the plane of the membrane by an aspartyl protease, resulting in a soluble MHC class I fragment composed of the lumenal domain of the heavy chain, beta(2)-microglobulin (beta(2)m), and peptide. We conclude that K3 not only directs internalization, but also targets MHC class I complexes to a dense endocytic compartment on the way to lysosomes in a ubiquitin-proteasome-dependent manner.
Contributions to the study of SMS spam filtering (2011)

The growth of mobile phone users has lead to a dramatic increasing of SMS spam messages. In practice, fighting mobile phone spam is difficult by several factors, including the lower rate of SMS that has allowed many users and service providers to ignore the issue, and the limited availability of mobile phone spam-filtering software. On the other hand, in academic settings, a major handicap is the scarcity of public SMS spam datasets, that are sorely needed for validation and comparison of different classifiers. Moreover, as SMS messages are fairly short, content-based spam filters may have their performance degraded. In this paper, we offer a new real, public and non-encoded SMS spam collection that is the largest one as far as we know. Moreover, we compare the performance achieved by several established machine learning methods. The results indicate that Support Vector Machine outperforms other evaluated classifiers and, hence, it can be used as a good baseline for further comparison.
Lipogenic enzyme activities in primary cultures of adult mouse hepatocytes (1988)

The effects of various unsaturated fatty acids such as oleic (18:1n-9), linoleic (18:2n-6) and arachidonic (20:4n-6) on the activities of fatty acid synthetase (FAS), malic enzyme (ME), glucose-6-phosphate dehydrogenase (G6PDH) and 6-phosphogluconate dehydrogenase (6PGDH) all were determined in primary cultures of mouse hepatocytes. Activities of FAS and ME were found to decrease with time in culture regardless of whether hepatocyte donors were fed diets containing polyunsaturated fatty acid-free hydrogenated cottonseed oil (HCTO) or corn oil (CO). On the other hand, while G6PDH activity also declined in cultured hepatocytes obtained from HCTO-fed mice, the activity of this enzyme increased in cells cultured from CO-fed mice. 6PGDH activity was found to increase in hepatocytes obtained from both diet groups. Neither 18:2 nor 20:4 when added to media could alter FAS or ME activities compared with those observed with either 18:1-containing or fatty acid-free media. Since lactic dehydrogenase activity and the rate of incorporation of [3H] leucine into FAS protein were unaltered with time in hepatocyte cultures, the decreased activities of FAS and ME cannot be attributed to a loss in cell viability during culture but rather appear to be specific for those enzymes which respond to diet hormones in vivo.
Loris - A Dependable, Modular File-Based Storage Stack (2010)

The arrangement of file systems and volume management/RAID systems, together commonly referred to as the storage stack, has remained the same for several decades, despite significant changes in hardware, software and usage scenarios. In this paper, we evaluate the traditional storage stack along three dimensions: reliability, heterogeneity and flexibility. We highlight several major problems with the traditional stack. We then present Loris, our redesign of the storage stack, and we evaluate several aspects of Loris.
Using pen input features as indices of cognitive load (2007)

Multimodal interfaces are known to be useful in map-based applications, and in complex, time-pressure based tasks. Cognitive load variations in such tasks have been found to impact multimodal behaviour. For example, users become more multimodal and tend towards semantic complementarity as cognitive load increases. The richness of multimodal data means that systems could monitor particular input features to detect experienced load variations. In this paper, we present our attempt to induce controlled levels of load and solicit natural speech and pen-gesture inputs. In particular, we analyse for these features in the pen gesture modality. Our experimental design relies on a map-based Wizard of Oz, using a tablet PC. This paper details analysis of pen-gesture interaction across subjects, and presents suggestive trends of increases in the degree of degeneration of pen-gestures in some subjects, and possible trends in gesture kinematics, when cognitive load increases.
Microtubule-associated tau protein positive neuronal and glial inclusions in ALS (2003)

Cognitive dysfunction in ALS may reflect abnormal tau protein metabolism.
Realization of controllable photonic molecule based on three ultrahigh‐Q microtoroid cavities (2017)

Abstract Three‐cavity photonic molecules have been realized in several platforms, but their structures and configurations are mostly fixed with limited tunability in the coupling strengths and individual resonant frequencies. Here, we demonstrate an experimental realization of a coupled triple‐cavity photonic molecule (TCPM) composed of three independently‐selectable ultrahigh quality microtoroids. By precisely tuning the inter‐cavity coupling strengths (via distances) and the resonant frequencies (via fine temperature control), as well as coupling the tapered optical fiber onto either the side or middle cavity, evolutions of the TCPM's supermodes are fully mapped and analyzed. Interesting phenomena, such as dark state and double anti‐crossing, emerge in this TCPM system. When the quality factors of the cavities are properly chosen, transition from double electromagnetically‐induced transparency to double electromagnetically‐induced absorption phenomena happens. Such fully‐controlled TCPM system sets a stage for future investigations of new physical effects including cavity‐QED with multiple coupled cavities and topologically protected photonic states. image
The Resource Management Regime and Private Property Rights and Interests - Is There an Untoward Tension between the Two? (2010)

This paper explores the relationship between the Resource Management (RMA) regime and private property rights. It discusses various RMA cases with the intent of illustrating that, while tension is oft reported between the RMA regime and private property rights, the two ought not to be treated or interpreted as competing in ways liable to undermine one or the other.
Direct Mass Spectrometric Monitoring of Solid Phase Organic Syntheses (2003)

Direct on-bead monitoring of solid-phase reactions is possible with soft laser desorption time-of-flight mass spectrometry (SLD-TOF MS) without prior cleavage from the resin if photocleavable phenacyl ester or o-nitroveratryl linker groups are employed.
rf plasma aerosol deposition of superconductive Y1Ba2Cu3O7−δ films at atmospheric pressure (1990)

Superconducting films of Y1Ba2Cu3O7−δ were produced by a radio frequency (rf) plasma aerosol evaporation technique at atmospheric pressure. Aqueous solutions of the ions were generated as an aerosol and the mist was injected into the plasma region, and then deposited onto substrates outside of both the plasma and flame regions. The substrate temperature was about 600 °C. The deposition rate is 0.01–100 μm/(min cm2) and the film thickness is 1–200 μm. For an ‘‘as-deposited’’ film on a single-crystalline MgO substrate (100), the onset temperature of the superconducting transition is 100 K, with a transition width (10–90%) of 3 K, and zero resistance at 91 K. For another film post annealed at 850±10 °C for 1 h, the onset temperature is 105 K, with a width of 6 K, and zero resistance at 91 K. Since this technique does not require a vacuum environment, it has potential for large scale production of thin films.
Antimicrobial activity ofStreptomyces species against mushroom blotch disease pathogen (2005)

Bacterial blotch caused by Pseudomonas tolaasii is still one of the main diseases in mushroom farms. Effective treatment of the infections caused by P. tolaasii is yet to be established. The isolation and identification of three Streptomyces species that showed antimicrobial activity against P. tolaasii NCPPB 2192(T) were described. Six strains were highly active with an inhibition zone more than 20 mm in diameter. They were assigned to the known Streptomyces cluster groups as S. rochei, S. lydicus and S. antibioticus. The fermentation, preliminary extraction and isolation of bioactive components were carried out. The bioactive compound may be a beta-lactam structurally related to the penicillins.
Inhibition of Vascularization in Tumor Growth (2002)

The transition to a vascular phase is a prerequisite for fast tumor growth. During the avascular phase, the neoplasm feeds only from the (relatively few) existing nearby blood vessels. During angiogenesis, the number of capillaries surrounding and infiltrating the tumor increases dramatically. A model which includes physical and biological mechanisms of the interactions between the tumor and vascular growth describes the avascular-vascular transition. Numerical results agree with clinical observations and predict the influence of therapies aiming to inhibit the transition.
Radiation response and other characteristics of the 9l rat glioma grown as an epigastric tissue isolate (1994)

Abstract We studied the 9L tumor as a tissue isolated epigastric implant. Data supporting its applicability to this site, including tumor blood flow, glucose metabolism, plating efficiency, radiation response, and histophatologic appearance, are described. Implants were performed on 175‐250 g male Fischer rats by tying 2–3 mm 3 pieces of tumor onto the proximal segment of the epigastric branch of the femoral artery. Characteristics of the model include recovered cell yields of 6.1 ± 4.2 × 10 7 cells/g; 19–23% plating efficiency; 5% relative surviving fraction at 19.3 and 27.6 Gy in air breathing and euthanized rats, respectively; mean glucose utilization rate of 229 ± 182 nmol/min/g; and tumor blood flow of 1.9–21.3 ml/min/100 g in 0.4–303 g tumors. These characteristics, for the first time, provide a common framework for simultaneous evaluation of tumor metabolism and radiation response. © Wiley‐Liss, Inc.
