Tetraamido Macrocyclic Ligand Catalytic Oxidant Activators in the Pulp and Paper Industry (2002)

One-time-use small molecule catalytic activation of H2O2 promises valuable benefits for the pulp and paper (P&P) industry. Tetraamido macrocyclic ligand (TAML) catalysts activate H2O2 to rapidly bleach wood pulp at high selectivity from room temperature to 90 °C, providing a new totally chlorine free (TCF) approach. In addition, TAML-activated peroxide bleaches "color" in ClO2 bleach plant effluents using low peroxide and minute catalyst concentrations in minutes at room temperature, giving 50 to 90% color reduction depending on the effluent stream. Here we summarize potential TAML/peroxide applications that promise to improve capital and operating costs, product quality, environmental performance, and energy efficiency. TAML-activated peroxide is applicable in diverse fields of technology among which the P&P field is but one.
Applications of Synthetic Peptides (2002)

The tremendous advances in the development of methods for the design and synthesis of peptides. pseudo-peptides and related compounds, as well as the corresponding advances in our understanding of peptide and protein structure, conformation, topography, and dynamics provides unique opportunities to apply designed synthetic peptides for an enormous variety of problems in chemistry, biology, and medicine. In addition, if these advances can be coupled to the advances in molecular biology and the human genome project, on the one hand, and asymmetric synthesis and catalysis, on the other, it should be possible to provide hitherto unavailable, indeed unthinkable, approaches to diverse areas of drug design, behavioral neuroscience, molecular immunology, chemotherapy, and a wide variety of other uses. Already it is clear that peptide therapy has enormous potential in such diverse areas as growth control, blood pressure management, neurotransmission, hormone action, satiety, addiction, pain, digestion, reproduction, and so forth. Nature has “discovered” that it can control nearly all biological processes by various kinds of molecular recognition, and that peptides and proteins are uniquely suited for this control because of their enormous potential for diversity and their unique physico-chemical properties. This finding may, perhaps, be most readily understood if one recognizes that, considering only the 20 normal eukaryotic amino acids, the number of unique chemical entities for a pentapeptide is 3,200,000 (205), for a hexapeptide it is 64,000,000 (206), and so on. Considered from this perspective, perhaps it is not unexpected that Nature has “discovered” that peptides and proteins can do it all, from providing structure and motion, to catalysis, to information transduction, to growth and maturation, and so on. The ability of the immune system in higher animals, including humans, to recognize literally millions of foreign materials made by Nature as well as humans, and to get rid of them as part of its survival strategy, is just one example that illustrates the potential of peptide-based drugs, therapeutics, and modulators of biological function. Despite the enormous potential of peptides and small proteins for these areas, surprisingly little advantage has been taken of the potential of these molecules as drugs and tools for use in basic and clinical research.
Purge Gases for the Removal of Airborne Molecular Contamination During the Storage and Transport Of Silicon Wafers (2004)

A method was developed to measure total hydrocarbons (THCs) to 1 part-per-trillion (ppt) concentration levels with a gas chromatograph with a flame ionization detector (GC/FID). This method was applied to measuring THCs in a front opening universal pod (FOUP) under static and purge conditions. XCDA purge gas was used for this experiment. XCDA gas is clean dry air (CDA) purified with Aeronex purification technology to remove moisture to less than 1 part-per-billion (ppb) and hydrocarbon, sulfur and siloxane contaminants to less than 1 ppt. The result from this experiment was that the FOUP’s environment contained ppb concentration levels of THCs under static conditions and ppt concentration levels of THCs under purge conditions. The following test involved a FOUP and a load port. The results from this test demonstrate that XCDA purge gas can be delivered to a FOUP from a load port with THC contaminants kept at ppt concentration levels. The final test involved exposing a silicon wafer to the FOUP’s environment under static and purge conditions. The wafer’s hydrocarbon contamination was less with the presence of a XCDA purge gas.

European Conference on Wireless Technology (2007)

A novel reconfigurable RF front-end architecture for future band-free mobile terminals is proposed. A single-path configuration and the use of single-band devices with distributed reconfigurable matching networks have the potential to achieve the optimum RF front-end for the transmission side. As the first step in verifying the proposed architecture, a reconfigurable quad-band power amplifier (PA) module is also presented. The 1W-class PA module using microelectromechanical systems switches and low temperature co-fired ceramic technology achieves the maximum power added efficiency of greater than 44% in the 0.9, 1.5, 2.0, and 2.6-GHz bands.
Tunnel studies of niobium films containing excess quasiparticles (1982)

The instability of the nonequilibrium state in superconducting niobium films is studied for wide-band (eV>3..delta..) and narrow-band (..delta..>>eV-3..delta..) sources of quasiparticles injected into the film. For a wide-band source, the critical instability current I/sub i/ was found to vary anomalously with the helium bath temperature. The pulse technique was used to measure the local heating temperature T/sub l/ in the neighborhood of a tunnel contact. The variation of I/sub i/ with T/sub l/ is not anomalous and is consistent with the theoretical temperature dependence ..beta../sub c/(T) of the critical power (V. F. Elesin, V. E. Kondrashov, and A. S. Sukhikh, Sov. Phys. Solid State 21, 1861 (1979)). Instability is found for a narrow-band source for the contacts having the lowest resistance. The instability current in this case decreases with falling temperature, in qualitative agreement with the theory of threshold instability in a superconductor.

The Effect of Age at Smoking Initiation on Lung Cancer Risk (1993)

It has been assumed that a younger age at initiation of cigarette smoking is associated with an increased risk of lung cancer, but previous studies have not adjusted for two strong risk factors, the amount smoked and duration smoked. We used data from a population-based case-control study with 282 histologically confirmed lung cancer cases matched to 3,282 random controls to determine whether age at initiation of smoking plays an independent role in the occurrence of lung cancer. After controlling for age, sex, and amount of tobacco exposure, men who began to smoke before age 20 had a substantially higher risk of developing lung cancer [odds ratio (OR) = 12.7; 95% confidence interval (CI) = 6.39-25.2] compared with men who began smoking at age 20 or older (OR = 6.03; 95% CI = 2.82-12.9). For women, the heavy increase in risk continued until age 25 (OR = 9.97; 95% CI = 4.68-21.2) compared with women who began smoking at age 26 or older (OR = 2.58; 95% CI = 0.53-12.4). There was no predisposition toward a specific histologic type of lung cancer. In this study, up to 52.4% of lung cancer cases in men and up to 73.0% of lung cancer cases in women could be attributed to this effect of early age of first smoking.
A hierarchical model for BGP routing policies (2009)

BGP routing policies are mainly used by network operators to enforce business relationships between Autonomous Systems (AS), and to prefer some routes over others. In this paper, we propose a hierarchical policy model to express each policy at the most appropriate level of abstraction. The model is structured around chains of filters that apply at a specific level of abstraction. To validate our approach, we implemented the model in a Java prototype and used it to reproduce several network-wide routing policies. In all studied networks, the model produced a high-level view of routing policies while preserving their semantics. Our model offers numerous advantages to network operators including, but not limited to, a better network documentation, an improved understanding of routing policies, redundancy suppression, and an easier way of managing their network.
A Novel Synthesis Route for Cu/ZnO/Al<sub>2</sub>O<sub>3</sub> Catalysts used in Methanol Synthesis: Combining Continuous Consecutive Precipitation with Continuous Aging of the Precipitate (2010)

Abstract A novel continuous method for the preparation of a ternary Cu/ZnO/Al 2 O 3 catalyst based on a cascade of micromixers and a tubular aging reactor is presented as a promising alternative route to the conventional batch process. Its application, in combination with immediate spray drying, enables monitoring of the formation of the final precursor by exchange reactions between initially separated phases during the aging step. These exchange reactions were successfully simulated by consecutive precipitation by using micromixers in series as analytical tool. After 60 min of continuous aging, calcination, and reduction, a catalyst is produced that exhibits an almost equal mass‐related activity in methanol synthesis compared to a commercial catalyst and an area‐related activity that is about 50 % higher.
Unexplained gastrointestinal symptoms and joint hypermobility: is connective tissue the missing link? (2009)

BACKGROUND Unexplained gastrointestinal (GI) symptoms and joint hypermobility (JHM) are common in the general population, the latter described as benign joint hypermobility syndrome (BJHS) when associated with musculo-skeletal symptoms. Despite overlapping clinical features, the prevalence of JHM or BJHS in patients with functional gastrointestinal disorders has not been examined. METHODS The incidence of JHM was evaluated in 129 new unselected tertiary referrals (97 female, age range 16-78 years) to a neurogastroenterology clinic using a validated 5-point questionnaire. A rheumatologist further evaluated 25 patients with JHM to determine the presence of BJHS. Groups with or without JHM were compared for presentation, symptoms and outcomes of relevant functional GI tests. KEY RESULTS Sixty-three (49%) patients had evidence of generalized JHM. An unknown aetiology for GI symptoms was significantly more frequent in patients with JHM than in those without (P < 0.0001). The rheumatologist confirmed the clinical impression of JHM in 23 of 25 patients, 17 (68%) of whom were diagnosed with BJHS. Patients with co-existent BJHS and GI symptoms experienced abdominal pain (81%), bloating (57%), nausea (57%), reflux symptoms (48%), vomiting (43%), constipation (38%) and diarrhoea (14%). Twelve of 17 patients presenting with upper GI symptoms had delayed gastric emptying. One case is described in detail. CONCLUSIONS & INFERENCES In a preliminary retrospective study, we have found a high incidence of JHM in patients referred to tertiary neurogastroenterology care with unexplained GI symptoms and in a proportion of these a diagnosis of BJHS is made. Symptoms and functional tests suggest GI dysmotility in a number of these patients. The possibility that a proportion of patients with unexplained GI symptoms and JHM may share a common pathophysiological disorder of connective tissue warrants further investigation.

Soluble Guanylate Cyclase α1–Deficient Mice: A Novel Murine Model for Primary Open Angle Glaucoma (2013)

Primary open angle glaucoma (POAG) is a leading cause of blindness worldwide. The molecular signaling involved in the pathogenesis of POAG remains unknown. Here, we report that mice lacking the α1 subunit of the nitric oxide receptor soluble guanylate cyclase represent a novel and translatable animal model of POAG, characterized by thinning of the retinal nerve fiber layer and loss of optic nerve axons in the context of an open iridocorneal angle. The optic neuropathy associated with soluble guanylate cyclase α1-deficiency was accompanied by modestly increased intraocular pressure and retinal vascular dysfunction. Moreover, data from a candidate gene association study suggests that a variant in the locus containing the genes encoding for the α1 and β1 subunits of soluble guanylate cyclase is associated with POAG in patients presenting with initial paracentral vision loss, a disease subtype thought to be associated with vascular dysregulation. These findings provide new insights into the pathogenesis and genetics of POAG and suggest new therapeutic strategies for POAG.

Robust Supervisory Control for Uniting Two Output-Feedback Hybrid\n Controllers with Different Objectives (2013)

The problem of robustly, asymptotically stabilizing a point (or a set) with\ntwo output-feedback hybrid controllers is considered. These control laws may\nhave different objectives, e.g., the closed-loop systems resulting with each\ncontroller may have different attractors. We provide a control algorithm that\ncombines the two hybrid controllers to accomplish the stabilization task. The\nalgorithm consists of a hybrid supervisor that, based on the values of plant's\noutputs and (norm) state estimates, selects the hybrid controller that should\nbe applied to the plant. The accomplishment of the stabilization task relies on\nan output-to-state stability property induced by the controllers, which enables\nthe construction of an estimator for the norm of the plant's state. The\nalgorithm is motivated by and applied to robust, semi-global stabilization\nproblems uniting two controllers.\n
Targeted Mutagenesis Mediated by the Triple Helix Formation (2003)

Oligonucleotides can bind in the major groove of duplex DNA and form triple helices in a sequence-specific manner , , , ). Progress in elucidating the third strand binding code has raised the possibility of developing nucleic acids as sequence-specific reagents for research and possibly clinical applications. Oligonucleotide-mediated triplex formation has been shown to prevent transcription factor binding to promoter sites and to block mRNA synthesis in vitro and in vivo (, , , ). Instead of using triplex formation to transiently block gene expression, however, we reasoned that it would be advantageous to use triple helix formation to target mutations to specific sites in selected genes in order to produce permanent, heritable changes in gene function and expression (, , ). In this approach, mutations are targeted to a selected site by linking the triplex-forming oligonucleotide to a mutagen so that the sequence specificity of the triplex formation can be imparted to the action of the mutagen (Fig. 1). Open image in new window Fig. 1. Strategy for triple helix-targeted mutagenesis. The 10-base triple helix-forming oligonucleotide is shown positioned above its target site in the supF gene (bp 167–176). The oligonucleotide is conjugated to a mutagen, 4′-hydroxymethyl-4,5′,8-trimethylpsoralen, which is targeted to intercalate between basepairs 166 and 167, as indicated by the arrow. Photoactivation of the psoralen generates adducts and thereby mutations at the targeted site.
A 14.7Mb/mm<sup>2</sup> 28nm FDSOI STT-MRAM with Current Starved Read Path, 52Ω/Sigma Offset Voltage Sense Amplifier and Fully Trimmable CTAT Reference (2020)

In this paper we present a read circuitry that tackles all STT-MRAM read challenges. First, a negative temperature coefficient (NTC) reference based on an MTJ in series with an “NTC” resistor circuit emulator is described. Then, an offset cancelled voltage sense amplifier using low read current and reference averaging is discussed. Measurement results show a maximum of 2% reference impedance error (vs. ideal) and 1.7% read error rate degradation (vs. technology intrinsic defectivity rate). A 14.7Mb/mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> memory density is also achieved, which is the best STT-MRAM published density for embedded applications.
Optimization of gain and energy conversion efficiency using front-facing photovoltaic cell luminescent solar concentrator design (2013)

Luminescent solar concentrator (LSC) windows with front-facing photovoltaic (PV) cells were built and their gain and power efficiency were investigated. Conventional LSCs employ a photovoltaic (PV) cell that is placed on the edge of the LSC, facing inward. This paper describes a new design with the PV cells on the front-face allowing them to receive both direct solar irradiation and wave-guided photons emitted from a dye embedded in an acrylic sheet, which is optically coupled to the PV cells. Parameters investigated include the thickness of the waveguide, edge treatment of the window, cell width, and cell placement. The data allowed us to make projections that aided in designing windows for maximized overall efficiency. A gain in power of 2.2 � over the PV cells alone was obtained with PV cell coverage of 5%, and a power conversion efficiency as high as 6.8% was obtained with a PV cell coverage of 31%. Balancing the trade-offs between gain and efficiency, the design with the lowest cost per watt attained

59‐2: Brightness Improvement of Reflective LCD (2020)

Through the comparison of the measurement results and the simulation results of the reflectivity, we have found an optical simulation method which can be applied to the reflectivity simulation of reflective LCD. The design of MRS can be optimized conveniently by the simulation method, and the best MRS design parameters were obtained. The optimized design of MRS may cause the RLCD high reflectivity.
Functional characterization of recombinant human HSP70 domains and interdomain interactions (2011)

ATPase and peptide-binding activity of recombinant human heat shock proteins HSP70A1B and HSC70 and two hybrid proteins derived from them was investigated. UV-spectral recorded data were used to characterize conformational rearrangements induced by domain replacement or HSP70-peptide interaction. It was shown that the N-terminal domain dramatically affects the substrate specificity of the C-terminal peptide-binding domain, which puts forward a new hypothesis for HSP70 chaperone machinery. On the other hand, the peptide-binding domain affected the ATPase activity of the recombinant proteins. There was a linear relationship between the ATPase activity and the peptide complex percentage. This connection can be used for quantification of HSP70 complexes with unlabeled peptides.
Salmonella food poisoning (1984)

During an outbreak of Salmonella typhimurium food poisoning in September 1983, in Sydney, 10 affected subjects were admitted to the same hospital. On admission to hospital, all patients were severely dehydrated; two patients developed acute tubular necrosis, while a third patient had myopericarditis. Bacteraemia was confirmed in two patients, in one of whom no organisms were isolated from stool cultures. Antibiotic agents were administered to all patients, because of the unusually severe nature of the infection. This outbreak illustrates that salmonella gastroenteritis, although usually fairly mild and self-limiting, can be a virulent disease resulting in serious complications. Appropriate management should include careful initial assessment of suspected cases, vigorous correction of fluid and electrolyte disturbances, and judicious use of antibiotic agents when bacteraemia or severe toxaemic features are present.
Effect of Pressure on the Mechanical Properties of Polymers. 3. Substitution of the Glassy Parameters for those of the Occupied Volume (1984)

Abstract Replacement of the expansion coefficient and of the bulk modulus and Bridgman constant of the occupied volume by the corresponding parameters of the glass leads to acceptable predictions for the shift factor, a p, for superposition of stress relaxation measurements as a function of pressure at constant temperature only at low pressures. Various assumptions which are commonly made to obtain free volume parameters from the constants of the WLF equations are examined and their adequacy is assessed.
