Protein Expression in Mycobacterium tuberculosis Differs with Growth Stage and Strain Type (2002)

Different phenotypes are displayed by Mycobacterium tuberculosis (M. tuberculosis) strains, fuelling speculation that certain strains are "hypervirulent" and able to evade host defenses better than others. Furthermore, differential antigen expression by M. tuberculosis strains may explain why certain patients are susceptible to a repeat episode of tuberculosis. The objective of this study was to compare protein expression by M. tuberculosis H37Rv and clinical isolates in order to determine whether differential protein expression contributes to the different phenotypes expressed by these strains. Expression of alpha-crystallin, the antigen 85 complex, PstS-1, L-alanine dehydrogenase and the 65 kDa antigen was analysed by Western blotting and enzyme-linked immunosorbent assays, using mouse monoclonal antibodies. We found no significant difference in the growth rate of the M. tuberculosis strains in vitro, and although M. tuberculosis protein expression showed phase variation during growth, expression seemed to be qualitatively, but not quantitatively, conserved in the strains investigated. These results have potentially important implications for vaccine development and serodiagnosis.
Incremental redundancy and bit-mapping techniques for high speed downlink packet access (2004)

A major evolution of the UMTS standard is high speed downlink packet access (HSDPA), which provides higher cell throughput and peak data rates of 10.8 Mbps. Key enabling technologies include fast scheduling, adaptive modulation and coding (AMC), as well as hybrid automatic repeat request (HARQ). To ease the implementation of HSDPA all coding elements are identical to standard WCDMA. In particular, the rate 1/3 turbo code is reused and no trellis coded modulation scheme has been introduced. The resulting drawbacks are analyzed and it is shown how they are efficiently counteracted by bit-mapping techniques accounting for the different bit reliabilities within a 16-QAM symbol. This paper focuses on the implementation and performance of HARQ and bit-to-symbol mapping functions. The performance of different HARQ schemes is compared for QPSK and 16-QAM and varying code rates. It is shown that depending on the code rate and the user terminal capabilities different HARQ types are favorable.

An Expanded Self-Antigen Peptidome Is Carried by the Human Lymph As Compared to the Plasma (2010)

The peptidome, generated by physiological tissue catabolism and transported by the pre-nodal lymph, is in addition to the self-peptidome generated in endosomal compartment. Unlike self antigen processed by local or nodal APC, which mostly produce epitopes constrained by the endosomal processing activity, self antigens present in the lymph could derived from a wider variety of processing pathways; including caspases, involved in cellular apoptosis, and ADAM and other metalloproteinases involved in surface receptor editing, cytokines processing and matrix remodeling. Altogether, expanding the tissue-specific self-repertoire available for the maintenance of immunological tolerance.

U.V. Induced Thermoluminescence on Natural Calcium Fluoride (1972)

Samples of a green variety of fluorite found at Circuit, Brazil, annealed at 580°C for 10 min and then at 400°C for 2 hr were exposed to 365 nm u.v. light. The transferred TL from deep trap to lower temperature trap gives rise to a glow curve containing peaks I, II, III', III and IV in a readout up to 400°C. This TL response was measured as a function of u.v. exposure time t and the result is not a saturation curve, but, TL tends to zero for large t indicating a simultaneous bleaching effect. The curve of TL vs number n of cycles in an exposure-readout cycle was obtained for different durations of exposure in each cycle. For large n the rate of decrease of log (TL) is independent of the time interval of exposure to u.v. light in each cycle. The effect of duration and temperature of pre-annealing on TL transfer under u.v. exposure as well as the dependence of transferred TL on previous gamma radiation were investigated. Finally a mathematical model is proposed.
Electronic Structure and Interface Properties of a Model Molecule for Organic Solar Cells (2009)

We study the electronic structure of 4,7-bis(5-methylthiophen-2-yl)benzo[c][1,2,5]thiadiazole (MTBT) and its interface properties with gold using X-ray photoemission spectroscopy (XPS), valence-band ultraviolet photoemission spectroscopy (UPS), X-ray absorption spectroscopy (XAS), as well as resonant photoemission (ResPES). MTBT can be regarded as a model molecule for PCPDTBT, a promising candidate for efficient bulk heterojunction solar cells. Almost no contribution of sulfur and only a weak contribution of nitrogen to the HOMO level is found. At the interface with gold, a strong chemical interaction between the sulfur of the benzothiadiazole and gold occurs, which may have consequences for interface properties in devices.
Microfluidic assembly of cationic-β-cyclodextrin:hyaluronic acid-adamantane host:guest pDNA nanoparticles (2013)

Traditionally, transfection complexes are typically formed by bulk mixing, producing particles with high polydispersity and limited control over vector size. Herein, we demonstrate the use of a commercial micro-reactor to assemble pDNA:cationic cyclodextrin:pendant polymer nanoparticles using a layer-by-layer approach. Our studies reveal that the particles formulated via microfluidic assembly have much smaller sizes, lower polydispersity, lower ζ-potentials, and comparable cell viability and transfection profiles in HeLa cells than bulk mixed particles. The complexes also show a flow rate-dependent stability, with particles formed at slower flow rates giving rise to more stable complexes as determined by heparin challenge. Our findings suggest that microfluidic reactors offer an attractive method for assembling reproducible, size-controlled complexes from multi-component transfection complex assemblies.
Ambient temperature compaction of polycarbonate powder (1997)

Abstract Solid‐state processing of polymer powders through compaction and sintering has potential advantages over conventional polymer processing methods; however, pressureless sintering of compacted polymer powders has often been unsuccessful. Room temperature compaction of polycarbonate (PC) powder was studied in an effort to better understand the fundamental mechanisms that control polymer compaction and sintering. It was found that differences in the degree of physical aging affect the compaction behavior of PC powder. The results presented in this paper show that the degree of physical aging of thermoplastic polymer powders, which can be influenced by commonly used powder handling operations such as drying and long term storage, can ultimately affect the ability of the powder to be successfully compacted at room temperature.
The Causes of the Parameters Changes of Soil Resistivity (2009)

The Causes of the Parameters Changes of Soil Resistivity The grounding of electrical installations is primarily concerned with safety; in particular, the prevention of electrical shock risks of human life. As such, a grounding system must be designed, tested and maintained to satisfy this primary aim. This scientific paper presents a survey of soil resistivity and how its value varies from geological and meteorological factors. Soil resistivity is not only a useful measurable that reflects subsurface structure, but also a basic parameter to the design of effective grounding and lightening prevention / protection system. The most significant variations occur from such parameters of soil resistivity as moisture content, chemical composition, porosity, conductivity, temperature, vertical thickness and divisions, etc. Knowledge of soil resistivity at the intended site provides a valuable insight into how the desired ground resistance value can be achieved and maintained over the life of the installation with the minimum cost and effort.

Scalable modular self-reconfigurable robots using external actuation (2007)

This paper presents a method for scaling down the size and scaling up the number of modules of self- re configurable systems by focusing on the actuation mechanism. Rather than developing smaller actuators, the main actuator is removed entirely. Energy instead comes from the environment to provide motion in prescribed synchronous ways. Prescribed synchronous motions allow much faster assembly times than random Brownian motion which has been used before. An instantiation of this idea is presented using a motion platform to induce motions based on the inertial properties of the modules and the timed actuation of small latching mechanisms.

Ginkgo biloba--an appraisal. (2007)

Ginkgo biloba has been used in traditional Chinese medicine for about 5000 years. A standardized preparation, EGb 761 has been recently prepared. The pharmacologically active constituents, flavonol glycosides and the terpene lactones are standardized. The terpene lactones comprise of ginkgolides A, B, C and bilobalides. The extract scavenges excess free radicals and pretreatment with EGb 761 reduces damage by free radicals in patients undergoing coronary bypass surgery. The action of platelet activating factor is antagonized and platelet aggregation is reduced. Blood flow is increased. Release of prostacyclines and nitric oxide was shown to be stimulated. Ginkgo biloba has been found to be useful in the treatment of Alzheimers disease and cognitive impairment. EGB 761 has shown beneficial effect in aging and mild cognitive impairment. Bilobalide has been shown to be protective against glutamate-induced excitotoxic neuronal death. Early studies indicate a potential role in age-related macular degeneration and some types of glaucoma. Anticancer action is related to antioxidant, anti-angiogenic and gene regulatory actions. Ginkgo biloba has shown overall improvement in about 65% of patients with cerebral impairment and a similar percentage suffering from peripheral vascular diseases. A recent study suggested that phytoestrogens in Ginkgo biloba may have a role as alternative hormone replacement therapy. Recent trials have not shown a beneficial effect of Ginkgo biloba in tinnitus and acute mountain sickness. Ginkgo biloba increased the bioavailability of diltiazem. The extract has been shown to protect against doxorubicin-induced cardiotoxicity and gentamicin-induced nephrotoxicity in animals. Ginkgo biloba inhibits microsomal enzymes and has a potential for drug interactions. Further studies to establish the efficacy of Ginkgo biloba are required.

Witnessing Genuine Multiphoton Indistinguishability (2019)

Bosonic interference is a fundamental physical phenomenon, and it is believed to lie at the heart of quantum computational advantage. It is thus necessary to develop practical tools to witness its presence, both for a reliable assessment of a quantum source and for fundamental investigations. Here we describe how linear interferometers can be used to unambiguously witness genuine n-boson indistinguishability. The amount of violation of the proposed witnesses bounds the degree of multiboson indistinguishability, for which we also provide a novel intuitive model using set theory. We experimentally implement this test to bound the degree of three-photon indistinguishability in states we prepare using parametric down-conversion. Our approach results in a convenient tool for practical photonic applications, and may inspire further fundamental advances based on the operational framework we adopt.
Multiplierless multilayer feedforward neural networks (2002)

A design algorithm for multiplierless 2-layer feedforward neural networks suitable for discrete input-output mapping is proposed in this paper. By using this algorithm, the obtained network has continuous valued weights at the first layer and single-term powers-of-two valued weights at the second layer such that no multiplications are needed in the computation after training. On the other hand, step function is used at the output layer and a simplified version of sigmoid function is used at the hidden layer as activation functions which simplifies digital hardware implementation further. Simulation results showed that such networks can retain nearly identical recall performance of the corresponding networks using continuous weights, while having increased computational speed in applications and reduced cost in digital hardware implementation.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Azoarenes with Opposite Chiral Configurations: Light‐Driven Reversible Handedness Inversion in Self‐Organized Helical Superstructures (2013)

On the other hand: Azoarene compounds with axially chiral binaphthyl units of the same and opposite chiral configurations were doped into achiral liquid crystals (LCs). They were found to efficiently induce self-organized helical superstructures, which could be reversibly tuned by light irradiation using trans–cis photoisomerization to change the handedness of the helix (see scheme) in LC hosts.

A hybrid approach to Internet connectivity for mobile ad hoc networks (2004)

Mobile ad hoc networks are autonomous, infrastructureless networks that support multihop communication through IP routing. This paper examines the use of mobile IP in order to provide global Internet connectivity to ad hoc networks that use an on-demand routing protocol. We present a hybrid scheme that uses techniques such as TTL scoping of agent advertisements, eavesdropping and caching agent and advertisements to combine the advantages of proactive and reactive approaches to providing connectivity. We present simulation results to show that our approach achieves excellent connectivity while keeping overhead costs low.
Optical modulation depth improvement in SCM lightwave systems using a dissymmetrization scheme (1994)

A scheme is proposed that permits the increase of the rms optical modulation depth (OMD) in SCM lightwave systems, without correlative increase of clipping-induced nonlinear distortion. This scheme is based on the addition to the SCM signal of low-pass filtered pulses, produced in synchronism with the peaks of the SCM signal, in order to prevent the clipping occurring during these peaks. An experiment demonstrating the feasibility is described. An rms OMD improvement of 4 and 5 dB has been obtained for a SCM band of 200-800 and 200-600 MHz, respectively.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
