Assessing the electrochemical properties of polypyridine and polythiophene for prospective applications in sustainable organic batteries (2016)

Conducting polymers are being considered promising candidates for sustainable organic batteries mainly due to their fast electron transport properties and high recyclability. In this work, the key properties of polythiophene and polypyridine have been assessed through a combined theoretical and experimental study focusing on such applications. A theoretical protocol has been developed to calculate redox potentials in solution within the framework of the density functional theory and using continuous solvation models. Here, the evolution of the electrochemical properties of solvated oligomers as a function of the length of the chain is analyzed and then the polymer properties are estimated via linear regressions using ordinary least square. The predicted values were verified against our electrochemical experiments. This protocol can now be employed to screen a large database of compounds in order to identify organic electrodes with superior properties.

Comparison of Different Membranes with Cultures of Keratinocytes from Man for Percutaneous Absorption of Nitroglycerine (1999)

The permeability barrier function of cell-culture membranes to the permeation of nitroglycerine was evaluated to find an alternative to skin from man for ex-vivo skin-permeation tests. The membranes were prepared, under submerged conditions, by inducing the growth of keratinocytes, from different donors, on a film of esterified jaluronic acid for different times (10, 20 and 30 days). Their permeability barrier functions were compared with those of some of the most widely used artificial membranes, silicone rubber (Silastic), cellulosic material (Cuprophan, Millipore HAWP), polysulphone membrane (Supor) and polytetrafluoroethylene membrane (TF-PTFE), and with those of biological membranes such as fresh and frozen skin, stratum corneum and epidermis from man, and hairless mouse skin. For each membrane the permeation profile was obtained and the flux was calculated. The permeation profiles for nitroglycerine were similar and linear in the first 2-3 h for all the synthetic membranes tested except TF-PTFE. For this membrane the profile was linear throughout the period considered and the amount permeating in 24 h (1603 microg cm(-2)) was significantly lower than those obtained for the other artificial membranes (between 1926 and 2508 microg cm(-2)). The amounts permeating through all the biological membranes in 24 h were in the range 520 to 781 microg cm(-2), except those for the keratinocyte-culture membranes, which were in the range 1730 to 2553 microg cm(-2). Prolonging the growth period of cultured keratinocytes did not affect nitroglycerine permeation. The findings suggest that these keratinocyte-culture membranes have some advantages--good reproducibility if obtained from the same donor; many membranes can be obtained from the same donor; the preparation is simple; they can be handled more easily than traditional cell-culture membranes; and they afford constant penetration rates for a longer period than synthetic membranes. The membranes could be used for preliminary in-vitro permeation studies.
Ordered copolyamide‐imides and copolyester‐imides (1972)

Abstract A group of copolyamide‐imides and copolyester‐imides completely ordered has been obtained by the reaction of aliphatic and aromatic diamines with symmetrical monomers possessing reactive imide group. The aromatic diimide‐amide and diimide‐ester monomers were prepared by means of the reaction of acidolysis between trimellitic acid imide and acetoxy derivative of aromatic diamines and diphenols. The diimide‐ester monomers with aliphatic substitutes were obtained by ester interchange between glycols and the methyl ester of trimellitimide. The polymerization reactions were carried out in a solution of polar solvents and the solated polymers were characterized with the object of estabilishing a relation between the properties and the structure of each one.
HIGH ENERGY TRANSURETHRAL MICROWAVE THERMOTHERAPY FOR THE TREATMENT OF PATIENTS IN URINARY RETENTION (2000)

In patients with severe co-morbidity transurethral microwave thermotherapy is often the only alternative to an indwelling catheter with obvious quality of life advantages. High energy transurethral microwave thermotherapy appears to be effective in these patients.
Energy-aware compress and forward systems for wireless monitoring of time-varying fields (2010)

Dense monitoring of time-varying 2D field by Wireless Sensor Networks (WSN) needs to define new strategies to aggregate and encode data according to 2D sensor deployments. In this paper optimal design of communication protocol for WSN is conveniently cast for a set of linear sensor networks (sensor arrays) synchronously monitoring a correlated 2D time-varying field (e.g., for tracking time variations). Sensors aggregate data hop-by-hop by compressing the new samples gathered from the sensor board and forwarding towards the next sensor in the route. Compression is based on a linear predictive encoding to exploit the correlation properties of the field. Cross-layer design of source, channel coding and medium access control are jointly analyzed for optimal resource allocation and interference management to minimize energy consumption. Seismic monitoring application is analyzed to corroborate the design approach.
Contractions of the isolated uterus stimulated by epidermal growth factor (1987)

Epidermal growth factor (EGF) produces uterine contractions in tissues removed from immature and adult rats. EGF produces both an increase in resting tone and the development of rhythmic contractions, and this effect is abolished by treatment with antibodies against EGF. The ED50 for this response is observed at an EGF concentration of 3.5 nM. This in vitro effect of EGF requires treatment of the animals in vivo with estradiol for 24 h before removal of uterine tissue. This effect of estradiol does not appear to be due solely to an induction of tissue EGF receptors. These results demonstrate a new activity of EGF and suggest a previously unrecognized function for this peptide growth factor.
The vitelliform macular dystrophy protein defines a new family of chloride channels (2002)

Vitelliform macular dystrophy (VMD/Best disease; MIM*153700) is an early-onset autosomal dominant disorder in which accumulation of lipofuscin-like material within and beneath the retinal pigment epithelium is associated with a progressive loss of central vision. Bestrophin, the protein product of the VMD gene, has four predicted transmembrane domains. There are multiple bestrophin homologues in the human, Drosophila, and Caenorhabditis elegans genomes, but no function has previously been ascribed to these proteins, and they show no detectable homology to other proteins of known function. Using heterologous expression, we show here that human, Drosophila, and C. elegans bestrophins form oligomeric chloride channels, and that human bestrophin is sensitive to intracellular calcium. Each of 15 missense mutations asscociated with VMD greatly reduces or abolishes the membrane current. Four of these mutant bestrophins were coexpressed with the wild type and each dominantly inhibited the wild-type membrane current, consistent with the dominant nature of the disease. These experiments establish the existence of a new chloride channel family and VMD as a channelopathy.
Building block approach and variable size memory for CMOS VLSIs (1983)

This report will discuss 10K to 20K CMOS VLSIs with a building block approach suitable for high speed and automated design. To accommodate diversified designers' demands, RAMs and ROMs have been designed to be size variable and applicable to the DA system. Three hierarchical levels are cell, block and chip. Two layer metals (aluminum) and one layer (poly-Si) were used for wiring.
Rough surface interferometry at 106 μm (1980)

An IR Twyman-Green interferometer is described. It uses a cw CO(2) laser as a light source operating at a 10.6-microm wavelength. Theoretical analysis and experimental measurements of the relationship between the contrast of the interference fringes and the rms roughness of test surfaces are discussed. Interferometric testing results and special alignment methods are shown for rough surface optics.
An analogue approach to the design of motion estimators for digital video encoding (2000)

We propose a new architecture which enables a motion estimation (ME) processor to be constructed using analogue components. At present, due to the arduous scale and nature of the computations required in digital hardware realisations, the ME processor is invariably the most complex and expensive component of a modern video codec. Our preliminary results indicate that very considerable reductions in size, power consumption and hence cost are available using our proposed method.
How to Fix the Inefficiency of Global Cap and Trade (2012)

Global cap and trade equalizes the price of emissions and leads to efficient abatement across countries, but sets the abatement level inefficiently low. It is set too low, because the global cap is the sum of individual country targets set on the basis of self-interest. The efficiency of a single price does not overcome the inefficiency of the public-goods problem inherent in global cap and trade. Fortunately, other policies lead to more cooperative and, hence, more efficient outcomes. Replacing the national quantity targets of global cap and trade with a global price target improves outcomes. To improve outcomes further, the price target is combined with a Green Fund. As we demonstrate by example, the Green Fund can induce cooperation between rich countries that want a high global price and poor countries that are more concerned with Green-Fund payments.
On the Theory of the Contact of the Helical Gear on the Tooth Normal Plane. (From the Patent of Wildhaber). (1995)

E. Wildhaber have made the very important works in the field of the theory of the gearing. He derived many important results only using the elementary geometry. It is very difficult to understand his theory for the reader. The author proved his theory of the contact of the helical gear on the tooth normal plane, which he used in his patent of circular arc tooth helical gear. And the author would like to introduce his artistic theory.
Investigation of the electronic properties of <i>in</i> <i>situ</i> annealed low-temperature gallium arsenide grown by molecular beam epitaxy (1992)

Current conduction through in situ annealed low-temperature gallium arsenide (LT GaAs) grown by molecular beam epitaxy (MBE) has been studied using Schottky diodes. The dominant transport mechanism in these films was found to be space-charge-limited current conduction in the presence of deep level states. We also examined two LT GaAs films, one with initially 4000 Å thick subsequently etched back to 2000 Å and the other sample with an initial thickness of 2400 Å, and found that the excess arsenic redistribution or clustering, carrier trap levels, and concentration depend strongly on the initial thickness of the LT GaAs film.
Crystal Engineering for π−π Stacking via Interaction between Electron-Rich and Electron-Deficient Heteroaromatics (2008)

New dipolar compounds containing alternating electron-rich thieno[3,2-b]thiophene units and electron deficient units have been synthesized. Compounds with 5-pyrimidinyl (compound 2) or benzothiazole (compound 5) as the electron-deficient unit were structurally characterized by the single-crystal X-ray diffraction method. The arrangement of the molecules is found to be one-dimensional slipped-pi-stack for 2. That of 5 is of slipped-pi-stack, albeit with a tilt angle between neighboring pi-stacks. The pi-pi interfacial distances of the molecules in the crystal lattice are 3.47 and 3.59 A for 2 and 5, respectively. On the basis of the crystal structure, compound 2, with negligible pi-pi slip along the short axis of the molecules, has a calculated electronic coupling value (0.153 eV) twice as large as that of the largest coupling of pentacene. Accordingly, the theoretically estimated hole mobility (mu(+)) for 2 (2.32 cm(2) s(-1) V(-1)) compares favorably with that of pentacene (1.93-5.43 cm(2) s(-1) V(-1)), despite of the larger reorganization energy for hole transport in 2. The symmetric intrastack S...C contacts found between the thieno[3,2-b]thiophene and pyrimidinyl units explain the unique features of the crystal structure of 2 and the resulting large electronic coupling.
Development of Motor Model of Rotor Slot Harmonics for Speed Sensorless Control of Induction Motor (2013)

SUMMARY This paper proposes a novel mathematical dynamic model to represent the steady‐state and transient‐state characteristics of rotor slot harmonics of an induction motor for sensorless control. Although it is well known that the rotor slot harmonics originate from the mechanical structure of the induction motor, a mathematical model that describes the relationship between the stator/rotor currents of the induction motor and the slot harmonics has not yet been proposed. Therefore, in this paper, a three‐phase model of the induction motor that depicts the rotor slot harmonics is developed by taking into consideration the magnetomotive force harmonics and the change in the magnetic air gap caused by the rotor slots. The validity of the proposed model is verified by comparing the experimental results and the calculated values. © 2013 Wiley Periodicals, Inc.

WSN07-6: A Directional MAC Protocol for Practical Smart Antennas (2006)

Recently, several MAC protocols using directional antennas, typically referred to as directional MAC protocols, have been proposed for wireless ad hoc networks. However, the MAC protocols in the previous studies were evaluated using simulation with ideal antenna forms. When using practical antenna beam forms, side lobes and back lobes exist which may cause new problems. In this paper, we evaluate the performance of the directional MAC protocol in the previous studies with practical antenna beam forms. In addition, we propose a directional MAC protocol that assumes practical antenna beam forms. The proposed MAC protocol mitigates data collisions due to the effects of minor lobes by the following two schemes. First, the nodes rotate directional receiving antenna beams in an idle state. Second, nodes transmit NAV (Network Allocation Vector) request frames to avoid collisions from neighboring nodes. By controlling the transmitting power, our protocol allows nodes to communicate with nodes beyond the omni-directional transmission range. The simulation results show that the proposed directional MAC protocol improves throughput performance compared to existing directional MAC protocol when using practical antenna beam forms.

Lacticin Q, a Lactococcal Bacteriocin, Causes High-Level Membrane Permeability in the Absence of Specific Receptors (2008)

To characterize the mode of action of lacticin Q (LnqQ), its membrane-permeabilizing activity was compared with that of nisin A because of the similar antimicrobial features of these compounds. Lipid II, the receptor for nisin A, was not required for LnqQ activity. LnqQ induced high-level membrane permeability in the absence of specific receptors.
Bits-to-Symbol Mappings for Superposition Coding (2011)

The last three decades have seen significant advances in the wireless communication field. As the data rates of wireless systems are increasing, the demand for mobile services also is increasing rapidly. Like other natural resources, radio spectrum suitable for mobile wireless communications is also limited. In order to keep up with this ever increasing demand, there is a requirement of new signal processing algorithms. Diversity is a technique used in wireless systems to combat the effects of fading and thereby improve reliability of data transfer. There are many ways in which algorithms can exploit diversity in wireless channels. Hybrid-automatic repeat request (H-ARQ) schemes and relaying mechanisms are two such diversity extracting techniques. Even though these diversity achieving techniques have been well understood in theory, there are many ways in which one can optimize these techniques for specific application scenarios.In this thesis, we focus on improving the performance of retransmission schemes and relaying systems. In the first part of the thesis, we improve the performance of H-ARQ schemes in the 3GPP- long term evolution (LTE) system by improving the performance of feedback signaling. We employ complex-field coding to extract the inherent frequency diversity available in the resources. Next, we provide a sub-optimal solution to the outage-optimal power allocation problem in incremental redundancy based H-ARQ system, whose performance is practically the same as that of the optimal solution. In the later part of the thesis, we propose a retransmission scheme based on superposition coding (SPC) for the symmetric relaying scenario. We provide packet error probability (PEP) expressions and solutions for the optimal fraction of power allocated for the partners' data. Finally, we study the optimal bits-to-symbol mappings for SPC and its effect on an H-ARQ scheme and the symmetric relaying scenario using SPC.
Absorption, Distribution and Excretion of OPB-2045 following a Single Subcutaneous Administration to Rats. (1998)

Examination was made of the absorption, distribution and excretion of radioactivity in SpragueDawly rats following a single subcutaneous administration of 14C-labeled OPB-2045 at 1 mg/kg, and the following results were obtained: 1. Serum concentrations of radioactivity were maximum (Cmax) of 0.032-0.033 μg eq./ml at 1 hr after administration in male and female rats. Radioactivity half-life in serum was 77.0 hr as determined at 48 hr to 168 hr postdosing in male and female rats. The area under the serum concentration-time curve (AUC0→∞) was 0.75 to 0.78 μg eq.·hr/ml. Radioactivity in blood cells accounted for 31.9-77.9% of total radioactivity in the blood. Radioactivity in the blood exceeded that in the serum. AUC0→∞ in the blood was 1.5 to 2 times that of the serum. 2. Radioactivity was highest in the pituitary gland, followed by the thyroid, adrenal glands, lungs and kidneys in male rats 1 hr postdosing. In tissues, it was 10 to 26 times higher than in the blood. At 8 and 24 hr postdosing, radioactivity in adrenal glands was extremely high, and 100 to 200 times that in the blood. At 72 and 168 hr postdosing, radioactivity was high in the adrenal and pituitary glands and kidneys. Its tissue distribution in female rats was essentially the same as in male rats. 3. Urinary and fecal excretion of radioactivity was 17.2-20.8% and 68.4-71.2% of the administered doses, respectively, with 9.1-9.3% remaining in the carcass at 168 hr postdosing. 4. Biliary and urinary excretion of radioactivity at 24 hr postdosing accounted for 34.1% and 14.2% the administered doses, respectively, in male rats whose bile ducts had been cannulated.
An integrated sp3t rf MEMS switch (2002)

In this paper, a novel multi-port MEMS switch is investigated. The switch is integrated on a chip of size 500μm × 500μm, while maintaining a high isolation between all ports up to 40 GHz. Electromagnetic (EM) simulation results are presented to verify the proposed concept. The switch is fabricated using the Multi-user MEMS processes MUMPs for integration on an Alumina substrate using flip-chip technology.
The Mechanism of Synergism Between Sulfur- and Phosphorus-Type EP Additives (1986)

A synergistic effect was observed for systems of phosphites and sulfur-type additives, while no interaction was observed for systems of phosphates and sulfur-type additives. The mechanism of synergism was studied by EPMA, FT-IR, GC-FPD, and MS. From a synergistic mixture, a new compound containing phosphorus and sulfur was detected. The new compound which was separated by distillation showed good antiwear properties comparable with the synergistic system and was identified as a thiophosphate. The synergism between the sulfur-type additive and phosphite may be caused by the formation of thiophosphate. The chemical reaction between them is discussed and a reaction formula is proposed.
