Organometallic Intermediates in the Controlled Radical Polymerization of Styrene by α-Diimine Iron Catalysts (2007)

The alpha-diimine iron complexes (R',R")[NN]FeCl2 ((R',R")[N,N] = R'-N = CR"-CR"= N-R') are efficient catalysts for the atom-transfer radical polymerization (ATRP) of styrene when R' and R" are electrondonating substituents and favor catalytic chain transfer (CCT) when electron-withdrawing substituents are employed. An organometallic pathway, alongside a halogen-atom-transfer equilibrium, is proposed to mediate the observed reactivity. The model alkyl complexes, (R',R")[N,N]FeCl2(R), where R = PhCH2 and Ph(Me)CH, were generated via treatment of (R',R'')[N,N]FeCl3 with RMgCl. The alkyl derivatives obtained from intermediate spin-state (R',R'')[NN]FeCl3 complexes were found to be stable to ca. -30 degrees C and favor CCT, whereas the alkyl derivatives derived from high-spin-state trichloride precursors are unstable above -78 degrees C and favor ATRP. Azo-initiated polymerizations of styrene are moderately controlled by alpha-diimine iron catalysts. The role of organometallic-mediated radical polymerization (OMRP) in the controlled polymerization of styrene is discussed: an analysis of the radical concentrations generated by the competing OMRP and ATRP equilibria indicates that the halogenophilicity of the Fe(II) catalyst dominates the carbophilic alkyl radical-trapping capacity of the Fe(II) species in this alpha-diimine catalyst system.
IL-6 and IL-13 in Induced Sputum of COPD and Asthma Patients: Correlation with Respiratory Tests (2012)

Our results confirmed that IL-6, but not of IL-13, is associated with respiratory disorders in both asthma and COPD patients.
Cyclobacterium jeungdonense sp. nov., isolated from a solar saltern (2013)

A horseshoe-shaped, orange-pigmented strain, HMD3055(T), was isolated from a solar saltern in Korea. Strain HMD3055(T) grew optimally at 25 °C and with a salt concentration of 3-5 %. The predominant quinone of strain HMD3055(T) was menaquinone (MK)-7. The major fatty acids of strain HMD3055(T) were iso-C15 : 0, summed feature 3 (comprising C16 : 1ω6c and/or C16 : 1ω7c) and summed feature 9 (iso-C17 : 1ω9c and/or 10-methyl C16 : 0). The polar lipids of HMD3055(T) consisted of phosphatidylethanolamine, one unidentified phospholipid, one unidentified aminolipid and five unidentified polar lipids. The phylogenetic tree based on 16S rRNA gene sequences showed that strain HMD3055(T) formed a distinct lineage within the genus Cyclobacterium. Strain HMD3055(T) was closely related to Cyclobacterium lianum (95.8 %), Cyclobacterium lianum HY9(T) (95.8 %), C. marinum DSM 745(T) (93.2 %) and C. amurskyense KMM6143(T) (92.6 %) form a distinct lineage from other members of the genus Cyclobacterium. The DNA G+C content of strain HMD3055(T) was 45.6 mol%. On the basis of the evidence presented in this study, it is concluded that strain HMD3055(T) represents a novel species of the genus Cyclobacterium, for which the name Cyclobacterium jeungdonense sp. nov. is proposed. The type strain is HMD3055(T) ( = KCTC 23150(T) = CECT 7706(T)).
Design and implementation of scalable IMS charging systems (2009)

Billing, charging and accounting are the most critical operational support activities for any telecommunications network operator. Through these activities operators recover costs for service provision, and make business profits. IMS charging is required at the services level as well as the transport level. In networks with QoS guarantees, it is necessary for user preferences of service quality levels be accommodated. This is critical when the cost of service has a strong relation to the service quality. There is a need to minimize resource utilization and costs related to charging and billing. Customized, efficient and user friendly service provision systems will enable the network operator to remain competitive. In this paper we explore the design of a user friendly efficient charging, billing and accounting system for 3GPP based IMS networks. We implement the system in a real IMS prototype, and perform a series of tests to determine the best charging schemes to apply for popular IMS services. User interaction with the system is achieved through interfaces created on the user agent.

Silver Antibacterial Bone Cement (1982)

An animal model was used to evaluate and compare silver methacrylate with gentamicin methacrylate in experimental Staphylococcus osteomyelitis. One tibia from each of 54 rabbits was innoculated with 4 X 10(6) CFU of S. aureus and inserted with prepolymerized PMM rods containing either 1% Ag2SO4, 2.5% gentamicin, or no additives. By six weeks, the mortality rate was 61% in controls, 22% in Ag-PMM animals and 6% in gentamicin-PMM animals. Bacterial counts from the bone of dying and surviving animals were significantly lower than controls, 23.6% of controls for the Ag-PMM treated and 6.0% for the gentamicin-PMM treated groups. All surviving animals were culture positive, except for three sterile bones obtained from the gentamicin-PMM group. In light of these results and the favorable characteristics as an antimicrobial agent, further investigation of silver in bone cement (or other vehicles) for the prevention or treatment of bone infection appears warranted.
Synthesis of 1,2,4-oxadiazole-, pyrrole- and 1,2,3-triazole-substituted (1,2,3-triazol-1-yl)furazans (2008)

The synthesis of tricyclic compounds with hitherto unknown combinations of heterocycles (1,2,3-triazol-1-yl)-1,2,5-oxadiazoles with 1,2,4-oxadiazol-3-yl, pyrrol-1-yl or 1,2,3-triazol-1-yl substituents at the furazan ring, was developed by interaction of corresponding substituted azidofurazans with 1,3-dicarbonyl compounds, and pyrrolyl derivatives were also synthesised by condensation of amino(1,2,3-triazol-1-yl)furazans with 2,5-dimethoxytetrahydrofuran.
Study on In-Flow Fluidelastic Instability of Triangular Tube Arrays Subjected to Air Cross Flow (2014)

The in-flow instability of cylinder arrays corresponds to the in-plane instability of U-bend tubes in steam generators. This rarely occurring phenomenon has recently been observed in a nuclear power plant in the U.S. For this reason, the importance of studying this instability has recently increased. The fluidelastic instability of a cylinder array caused by cross-flow was found to easily occur in air-flow and hardly in water-flow in our previous report. The present report introduces the results of this phenomenon in several patterns of triangular cylinder arrays in air-flow. The pitch spacing between cylinders is one of the parameters, which varies from P/D = 1.2 to 1.5, for a five-by-five cylinder array. The instability is examined both in the in-flow direction and in the transverse direction. The test cylinders are supported with thin plates to move in one direction. The number and the location of the flexibly supported cylinders are the other parameters. Differences between the instability in the in-flow and in the transverse direction are found. Among these differences the most important is the fact that the fluidelastic instability has not been observed for a single flexible cylinder in the in-flow direction, although it is observed in the transverse direction. However, the present preliminary results suggest that the in-flow instability may be estimated with the Connors' type formula as likely as in the transverse direction case.
Using Nuances of Emotion to Identify Personality (2021)

Past work on personality detection has shown that frequency of lexical categories such as first person pronouns, past tense verbs, and sentiment words have significant correlationswith personality traits. In this paper, for the first time, we show that fine affect(emotion) categories such as that of excitement, guilt, yearning, and admiration aresignificant indicators of personality. Additionally, we perform experiments to show thatthe gains provided by the fine affect categories are not obtained by using coarse affectcategories alone or with specificity features alone. We employ these features in five SVMclassifiers for detecting five personality traits through essays. We find that the use offine emotion features leads to statistically significant improvement over a competitivebaseline, whereas the use of coarse affect and specificity features does not.
Alteration of glutathione transferase isoenzyme concentrations in human renal carcinoma (1987)

Glutathione transferase (GST) activity in the cytosolic fractions of four renal cortex tumors was found to be lower (1.85-3.4 times) than that present in the corresponding non-tumor cytosolic fractions. Glutathione transferase of both tumor and non-tumor kidney was purified by affinity chromatography and separated into five peaks at pH 4.7, 8.0, 8.4, 8.7 and 9.0 by isoelectric focusing. In the chromatogram of tumor tissues, the activity associated with the 'acidic' peak increased significantly, whereas the activities associated with 'basic' peaks all decreased in comparison with the corresponding peaks of non-tumor tissues. The acidic GST of human kidney is immunologically identical to GST pi, confirming that it is a good marker for human tumors.
Class of Exactly Solvable Models of Excitable Media (1998)

We introduce a class of exactly solvable reaction diffusion models of excitable media with nondiffusive control kinetics and the source term in the diffusion equation depending only parametrically on the control variable. A pulse solution can be found in the entire domain without any use of singular perturbation theory. We reduce the nonlinear eigenvalue problem for a steadily propagating one-dimensional pulse to a set of transcendental equations which can be compactly solved analytically within any power of the smallness parameter $\ensuremath{\varepsilon}$.
Use of the Telescopic Plate Spacer in Treatment of Cervical and Cervicothoracic Spine Tumors (2002)

OBJECTIVE We investigated the mechanical and in vivo properties of a novel device, called the telescopic plate spacer (TPS), designed to promote restoration of height, alignment, and stability after cervical corpectomy for tumor. METHODS The device first underwent mechanical testing. Comparisons were made with a commercially available anterior cervical plate. A caprine study was then performed. Twelve goats underwent a cervical corpectomy and placement of either a TPS filled with autograft or a plate and autograft. The animals were killed at 28 weeks and assessed for fusion. A prospective human study was then conducted. Fifteen patients with cervical or cervicothoracic tumors underwent corpectomy and placement of allograft-filled TPS. End points included pain scores and radiographic assessment of vertebral height, alignment, and stability. RESULTS In the mechanical study, the TPS outperformed the anterior cervical plate in all modalities except for torsion stiffness and tension-bending failure load. The caprine study demonstrated fusion in six of six cases at 28 weeks in the TPS group, compared with four of six cases in the plate and autograft group. In the human study, patients (n = 15) were stabilized with the TPS after corpectomy (range, 1–3 levels; average, 1.7 levels). There were no failures of instrumentation or neurological deterioration. Stability was achieved in all patients, with an average follow-up of 9 months. Durable improvements in pain scores (P = 0.001), vertebral height (P = 0.002), and reduction of kyphosis (P = 0.046) were achieved. CONCLUSION The TPS can be used to restore height, alignment, and stability after corpectomy.
Evolution of feeding specialization in Tanganyikan scale-eating cichlids: a molecular phylogenetic approach (2007)

The present evolutionary analyses of feeding ecology and morphology based on the obtained phylogenetic tree demonstrate for the first time the evolutionary process leading from generalised to highly specialized scale eating, with diversification in feeding morphology and behaviour among species.
Decomposition and combustion of EVA and LDPE alone and when fire retarded with ATH (2000)

Conventional thermogravimetric analysis (TGA) and a controlled atmosphere horizontal tube furnace have been used to study thermal degradation, in air and nitrogen, of ethylene–vinyl acetate copolymer (EVA) and low-density polyethylene (LDPE). The addition of aluminium oxide trihydrate (ATH) as a fire retardant was investigated. At 400 °C and at 450 °C, in both air and nitrogen, LDPE showed greater thermal stability in conventional TGA than the EVA copolymer. However, in the tube furnace experiments, at both temperatures, EVA showed comparable thermal stability to LDPE in nitrogen, and superior thermal stability to LDPE in air. This is thought to be the result of the formation of a protective layer, which is more effective at 400 °C than at 450 °C. In combination with approximately 55% ATH, the rate of mass loss of LDPE is significantly reduced at 400 °C, but the rate of mass loss of EVA is significantly increased. This may result from the evolution of water disrupting the protective layer. At 450 °C, ATH reduces the rate of mass loss of both LDPE and EVA to a similar extent in the absence of a coherent protective layer. © 2000 Society of Chemical Industry
Extraction of silymarin compounds from milk thistle (Silybum marianum) seed using hot, liquid water as the solvent (2002)

High value specialty chemicals are usually obtained from natural products by extracting with generally regarded as safe (GRAS) solvents. Because organic solvents are quite often used, high operating and disposal costs often occur. When compared to traditional solvents, water can be viewed as an interesting alternative because of its low operating and disposal costs. Milk thistle contains compounds (taxifolin, silychristin, silydianin, silybinin A and silybinin B) that display hepatoxic protection properties. This paper examines the batch extraction of silymarin compounds from milk thistle seed meal in 50'C, 70'C, 85'C and 100'C water as a function of time. For taxifolin, silychristin, silybinin A and silybinin B, extraction with 100' C water resulted in the highest yields. After 210 min of extraction at 100'C, the yield of taxifolin was 1.2 mg per g of seed, while the yields of silychristin, silybinin A and silybinin B were 5.0, 3. 7 and 6.5 mg per g of seed, respectively. The overall diffusion coefficients for the four compounds increased with temperature and ranged from 0.14 x 10^ 10 to 4 x10 ^ 10 m2 /sec, indicating that the diffusion coefficients could potentially be used for quantitative comparisons of extraction conditions. The ratios of the extracted compounds, and particularly the ratios at long extraction times, showed that the more polar compounds (taxifolin and silychristin) were preferentially extracted at 85'C, while the less polar silybinin was preferentially extracted at 100'C.
Operational Transformation In Co-Operative Editing (2016)

Cooperative Editing Systems in real-time allows a virtual team to view and edit a shared document at the same time. The document shared must be synchronized in order to ensure consistency for all the participants. This paper describes the Operational Transformation, the evolution of its techniques, its various applications, major issues, and achievements. In addition, this paper will present working of a platform where two users can edit a code (programming file) at the same time.
Uninterruptible Power Supply for Critical AC Loads -- A New Approach (1974)

An uninterruptible ac supply system consisting of two power sources (static inverter and ac line) and a thyristor switch is presented. The thyristor switch is operated in such a way that the equalization current flow between the sources is prevented. Consequently continuous parallel operation of the sources may be applied. Faults in one of the sources do not affect the voltage supplied to the load. In order to obtain these features the trigger mode of the switch must meet certain requirements. The analysis of these requirements is given and an implementation of the system is presented. Test results are illustrated by oscillograms. The advantages of the system are that 1) load transfer is performed in an instantaneous and smooth way, 2) the system is able to deliver large inrush currents required by the load and to blow fuses in branch circuits of the load, and 3) no voltage monitors are required.
Human Macrophages, but Not Dendritic Cells, Are Activated and Produce Alpha/Beta Interferons in Response to Mopeia Virus Infection (2004)

Lassa virus (LV) and Mopeia virus (MV) are closely related members of the Arenavirus genus, sharing 75% amino acid sequence identity. However, LV causes hemorrhagic fever in humans and nonhuman primates, whereas MV cannot induce disease. We have previously shown that antigen-presenting cells (APC)-macrophages (MP) and dendritic cells (DC)-sustain high replication rates of LV but are not activated, suggesting that they play a role in the immunosuppression observed in severe cases of Lassa fever. Here, we infected human APC with MV and analyzed the cellular responses induced. MV infection was productive in MP and even more so in DC. Apoptosis was not induced in either cell type. Moreover, unlike DC, MP were early and strongly activated in response to MV, as shown by the increased surface expression of CD86, CD80, CD54, CD40, and HLA-abc and by the production of mRNA encoding alpha interferon (IFN-alpha), IFN-beta, tumor necrosis factor alpha and interleukin-6. In addition, MV-infected MP produced less of the virus than DC, which was related to the fact that these cells secreted IFN-alpha. Thus, the strong activation of MP is probably a major event in the control of MV infection and may be involved in the induction of an adaptive immune response in infected hosts. These results may explain the difference in pathogenicity between LV and MV.
Automated external defibrillators for home use. (2005)

The Philips HeartStart Home Defibrillator is an automated external defibrillator (AED) that is approved for home use by untrained users. Most cardiac arrests occur in the home, so a rapid response with cardiopulmonary resuscitation (CPR) and defibrillation is critical for survival. No prospective studies demonstrate that the use of AEDs in the home by untrained persons improves health outcomes. Further investigation is needed to determine the benefit and harm of AEDs in the home.
Thermoregulatory responses to combined moderate heat stress and hypoxia (2016)

While sudomotor responses and the initiation of cutaneous blood flow elevations are unaffected, hypoxia differentially effects regional SkBF responses during moderate passive heating.
Noninvasive radio frequency for skin tightening and body contouring. (2013)

The medical use of radio frequency (RF) is based on an oscillating electrical current forcing collisions between charged molecules and ions, which are then transformed into heat. RF heating occurs irrespective of chromophore or skin type and is not dependent on selective photothermolysis. RF can be delivered using monopolar, bipolar, and unipolar devices, and each method has theoretical limits of depth penetration. A variant of bipolar delivery is fractional RF delivery. In monopolar configurations, RF will penetrate deeply and return via a grounding electrode. Multiple devices are available and are detailed later in the text. RF thermal stimulation is believed to result in a microinflammatory process that promotes new collagen. By manipulating skin cooling, RF can also be used for heating and reduction of fat. Currently, the most common uses of RF-based devices are to noninvasively manage and treat skin tightening of lax skin (including sagging jowls, abdomen, thighs, and arms), as well as wrinkle reduction, cellulite improvement, and body contouring.
Rotor position estimation in a switched reluctance drive using recursive least squares (2000)

This paper describes a new algorithm for the estimation of rotor position in a switched reluctance motor. It is based on a recursive least-squares estimator deducing both position and speed. A particular advantage of the algorithm is its ability to extract information about rotor position at very low speeds (one electrical cycle per minute) from voltage and current waveforms sampled only at the converter switching frequency. Experimental results for a 12/8 motor demonstrate that estimation is possible over the full range of operating conditions, including the field-weakening region, with a typical accuracy of better than two mechanical degrees. The paper also illustrates the performance of the algorithm by showing it operating within a sensorless position controller.
Cold-sensitive, menthol-insensitive neurons in the murine sympathetic nervous system (2004)

Several mechanisms have been implicated in underlying the perception of cold, most notably the activation of TRPM8 and TRPA1. We have used ratiometric calcium imaging to reveal a population of neurons in the superior cervical ganglion (SCG) of the mouse that respond to cooling but are insensitive to menthol. Furthermore we show that the expression of the mRNA transcripts encoding the recently identified noxious cold-sensitive channel TRPA1 but not TRPM8 are expressed in the SCG. These data provide evidence for a population of cold-responsive neurons in the SCG whose cold-responsiveness could be mediated by the activation of TRPA1 and suggest that the sympathetic nervous system may play a direct role in mediating sympathetic responses to cold temperatures.
Prevention of Spinal Bone Loss by Potassium Citrate in Cases of Calcium Urolithiasis (2002)

Potassium citrate, a commonly used drug for the prevention of recurrent nephrolithiasis, may avert age dependent bone loss. Spinal bone density increased in most patients when it normally decreases.
Browning Inhibition in Fresh‐cut‘Fuji’Apple Slices by Natural Antibrowning Agents (2006)

ABSTRACT Response surface methodology was used to study the effect of antibrowning agents (4‐hexylresorci‐nol, glutathione, N‐acetylcysteine, and ascorbic acid) and storage time (14 d) on the color of minimally processed Fuji apples. The selected color parameters were L *, a *, b *, hue angle ( h *), and color difference (ΔE*). Storage time had a significant effect on all the studied color parameters ( P ± 0.05). 4‐hexylresorcinol showed the most effective individual effect on keeping constant a *values ( P ± 0.0001). Besides, the interaction of N‐acetylcysteine/ glutathione was found to have a significant effect ( P ± 0.05) on maintaining a * values over time. On the other hand, individual treatment with N‐acetylcysteine in concentrations higher than 0.75% w/v may be used to preserve a *and h *.According to the F ‐test, 4‐hexylresorcinol and N‐acetylcysteine ( P ± 0.05) displayed a significant individual effect on ΔE*, indicating that ΔE* decreased when increasing the concentration of these antibrowning agents. Nevertheless, color difference went down when 4‐hexylresorcinol concentration increased up to 0.5%, but higher concentrations of this agent led to an increase in ΔE* that indicates browning.
