‘Candidatus Burkholderia calva’ and ‘Candidatus Burkholderia nigropunctata’ as leaf gall endosymbionts of African Psychotria (2004)

Phylogenetic 16S rRNA gene analysis was used to assign the bacterial leaf-nodulating endosymbionts of two tropical African Psychotria species to the genus Burkholderia. The microsymbionts of the different Psychotria hosts were recognized as distinct and novel species of Burkholderia on the basis of relatively low intersequence similarities and sufficiently large evolutionary distances when compared with each other and their closest validly named neighbours. The obligate endosymbiotic nature of the bacteria prevented their in vitro cultivation and the deposition of type strains to culture collections. Therefore, the provisional status Candidatus is assigned to the bacterial partners of Psychotria calva and Psychotria nigropunctata, with the proposal of the names 'Candidatus Burkholderia calva' and 'Candidatus Burkholderia nigropunctata', respectively.

H 1 ,  Li7, and F19 nuclear magnetic resonance and ionic conductivity studies for liquid electrolytes composed of glymes and polyetheneglycol dimethyl ethers of CH3O(CH2CH2O)nCH3 (n=3–50) doped with LiN(SO2CF3)2 (2002)

Solid polyethyleneoxides (PEO) are in effect “polymer liquids” due to their flexibility and high solubility for alkaline salts. To clarify the role of PEO in electrolyte systems, electrolytes composed of members of the “glyme family” [i.e., diglyme(DG), triglyme(TG), tetraglyme(TeG), pentaglyme(PG), and polyethyleneglycol dimethyl ethers(PEGDM)] doped with LiN(SO2CF3)2 were investigated. PEGDMs form a series of low molecular weight PEO-like homologues with molecular weights between 400 and 2500. Electrolytes of the glymes and PEGDMs were prepared for two salt concentrations (ether oxygen: lithium; O:Li) 20:1 and 10:1. The ionic conductivities and the self-diffusion coefficients of the solvent, anion and lithium ions in the electrolytes were measured using pulsed-field gradient spin-echo (PGSE) H1, F19, and Li7 NMR, respectively. From the spin-lattice relaxation times (T1) it was found that the segmental motions of the CH2CH2O moiety and the lithium hopping motions are correlated and that the rate of the segmental motions decreases as the molecular size of the solvent increases. The ionic conductivities calculated from the diffusion coefficients are compared with the experimental ac ionic conductivities. The diffusion and ion conduction mechanisms are discussed and the lithium ion–solvent interactions are shown to depend on the solvent size.
Controlling exit site infections: Does it decrease the incidence of catheter‐related bacteremia in children on chronic hemodialysis? (2009)

The aim of this retrospective study was to investigate whether the application of a chlorhexidine-impregnated dressing (Biopatch) at the exit site of tunneled-cuffed hemodialysis catheters has any effect on the incidence and etiology of catheter-related bacteremia (CRB). This study was carried out over a 5-year period in a single center, where, in the first 2(1/2) years, the exit sites were cleansed with betadine at every hemodialysis session and then covered with a transparent dressing (pre-Biopatch Era). During the next 2(1/2) years, Biopatch was applied to the exit site once a week after cleansing with betadine, and then covered with a transparent dressing (Biopatch Era). The application of Biopatch significantly decreased the incidence of exit site infections (ESI) (P<0.05). However, there was no difference in the incidence of CRBs or their microbiological distribution. The improved ESI rate had no effect on the overall catheter survival time. The antimicrobial sensitivities of the Gram-positive microorganisms were statistically different for the 2 different types of infections (P<0.05). In conclusion, even though Biopatch is effective in decreasing the incidence of ESI, it has no effect on the incidence of CRB, the etiology of CRB, or the overall catheter survival time. The distinct difference between the antimicrobial sensitivities of the ESI and CRB suggests that they are not a spectrum of the same pathogenesis. These preliminary data support the intraluminal pathogenesis of CRB, rather than the exit site as a possible entry point for the extraluminal route.
Reputation and Coalitions in Medieval Trade: Evidence on the Maghribi Traders (1989)

This article examines the economic institution utilized during the eleventh century to facilitate complex trade characterized by asymmetric information and limited legal contract enforceability. The geniza documents are employed to present the “coalition”, an economic institution based upon a reputation mechanism utilized by Mediterranean traders to confront the organizational problem associated with the exchange relations between merchants and their overseas agents. The the oretical framework explains many trade-related phenomena, especially why traders utilized specific forms of business association, and indicates the interrelations between social and economic institutions.
New permittivity measurements of seawater (1998)

We have measured the permittivity of representative samples of natural seawater, synthetic seawater, and aqueous NaCl solutions over the frequency range 3–20 GHz, in 0.1‐GHz steps and over the temperature range −2°–30°C in 1° steps. Additional measurements have been made at spot frequencies (23.8, 36.5, and 89 GHz) and at selected temperatures between −2° and 3O°C. The data from these measurements have allowed us to deduce an interpolation function for ε( υ t, S ) in the ranges 2 ≤ υ ≤ 20 GHz, −2° ≤ t ≤ 30°C, and 20‰ ≤ S ≤ 40‰ with a precision of 1%. If the frequency range is extended up to 40 GHz, the precision of the interpolation function is about 3%.The data have also allowed us to compare the permittivities of natural seawater, synthetic seawater, and aqueous NaCl solution with the same salinities. Natural and synthetic seawater have the same permittivities within a 1% experimental error estimate. An aqueous NaCl solution has a significantly different permittivity (up to about 6% difference, depending upon the frequency and temperature).

MiR-183/-96/-182 cluster is up-regulated in most breast cancers and increases cell proliferation and migration (2014)

The miR-183/-96/-182 cluster is up-regulated in most breast cancer. It functions as an oncogene in breast cancer as it increases cell proliferation and migration.
Side-Chain Role in Chemically Sensing Conducting Polymer Field-Effect Transistors (2003)

The role of polymer side chains in conferring selectivity to a sensing organic thin-film transistor is investigated. Alkyl- and alkoxy-substituted regioregular polythiophenes are used as active layers, and a set of volatile organic compounds carrying different chemical functionalities are employed as analytes. The responses of both polymer-based transistor and quartz crystal microbalance sensors are evaluated and compared; the sensing mechanisms involving weak interactions between the analyte functionalities and the polymers' side chains are discussed as well.
A Fresh Look at Small-Granularity Role-Based Access Control (2001)

Small-granularity role based access control offers an effective solution to reduce the damage an intrusion can cause to your organization. We describe a new dynamic activation of roles, with automatic de-activation if the role is no longer used. This allows us to further decrease the granularity of roles, and use the roles as input to an anomaly based Intrusion Detection System. To show how easy it can be to add Role-Based Access Control to an existing platform, we briefly discuss a simple implementation for a WWW based Intranet.
Layered polymeric capsules inhibiting the activity of RNases for intracellular delivery of messenger RNA (2015)

Intracellular delivery of messenger RNA (mRNA) is a promising approach for experimental and therapeutic manipulation of cellular activity. However, environmental RNase hinders reliable handling of mRNA for experimental and therapeutic use. In this study, biodegradable capsules composed of dextran sulfate and poly-l-arginine in the layer-by-layer (LbL) fashion are employed for the protection and delivery of mRNA. Our results demonstrate that addition of RNase inhibitors to mRNA while co-precipitation with CaCO<sub>3</sub> and subsequent LbL encapsulation are both crucial to preserve the integrity of mRNA. The expression of functional luciferase enzyme in HEK293T human embryonic kidney cells after incubation with synthetic luciferase-encoding mRNA capsules indicates the reliability of the encapsulating system and cellular intake of functional mRNAs. These improvements in mRNA encapsulation should provide essential basis for microcapsule-based mRNA delivery for further applications.
A Review on Vehicle Classification and Potential Use of Smart Vehicle-Assisted Techniques (2020)

Vehicle classification (VC) is an underlying approach in an intelligent transportation system and is widely used in various applications like the monitoring of traffic flow, automated parking systems, and security enforcement. The existing VC methods generally have a local nature and can classify the vehicles if the target vehicle passes through fixed sensors, passes through the short-range coverage monitoring area, or a hybrid of these methods. Using global positioning system (GPS) can provide reliable global information regarding kinematic characteristics; however, the methods lack information about the physical parameter of vehicles. Furthermore, in the available studies, smartphone or portable GPS apparatuses are used as the source of the extraction vehicle's kinematic characteristics, which are not dependable for the tracking and classification of vehicles in real time. To deal with the limitation of the available VC methods, potential global methods to identify physical and kinematic characteristics in real time states are investigated. Vehicular Ad Hoc Networks (VANETs) are networks of intelligent interconnected vehicles that can provide traffic parameters such as type, velocity, direction, and position of each vehicle in a real time manner. In this study, VANETs are introduced for VC and their capabilities, which can be used for the above purpose, are presented from the available literature. To the best of the authors' knowledge, this is the first study that introduces VANETs for VC purposes. Finally, a comparison is conducted that shows that VANETs outperform the conventional techniques.
The deeva autonomous vehicle platform (2015)

This paper presents the design, the setup, and the architecture of a new class of autonomous vehicles prototype. The car is equipped with 26 cameras, divided into 13 stereo pairs. Four stereo systems are dedicated to the reconstruction of the near area surrounding the vehicle, other nine are dedicated to the 3D reconstruction of the far driving area. Additionally four laserscanners, and a high performance GPS/IMU unit provide more information on the ground truth to measure the validity of the data obtained with vision. The autonomous driving system, the perception system, and the processing system have been installed in the vehicle taking extra care for an as-clean-as-possible integration with te aim of setting a new state of the art level for this kind of setup. A Human Machine Interface, allows the driver to control all the functions of the systems using a touch screen. A high precision synchronization system coupled with a custom software architecture allows to obtain recordings from all sensors installed.
Beam Pattern (Diffraction) Correction for Ultrasonic Attenuation Measurement (1984)

The measurement of tissue attenuation from pulse-echo data has been widely investigated. This paper examines correction of the measurements for the effect of the transducer beam. Computer and experimental studies are performed on a number of reflectors including smooth and rough planes, ideal point scatterers, T.M. material and liver and spleen tissue. It is shown that the corrections obtained from T.M. phantom material differ from those obtained using in vivo tissue as the reflector and corrections for liver and spleen differ markedly. Comment is made on the possibility of using "beam correction" itself as a tissue characterization parameter.
Hybrid quantum-classical algorithms and quantum error mitigation (2021)

Quantum computers can exploit a Hilbert space whose dimension increases exponentially with the number of qubits. In experiment, quantum supremacy has recently been achieved by the Google team by using a noisy intermediate-scale quantum (NISQ) device with over 50 qubits. However, the question of what can be implemented on NISQ devices is still not fully explored, and discovering useful tasks for such devices is a topic of considerable interest. Hybrid quantum-classical algorithms are regarded as well-suited for execution on NISQ devices by combining quantum computers with classical computers, and are expected to be the first useful applications for quantum computing. Meanwhile, mitigation of errors on quantum processors is also crucial to obtain reliable results. In this article, we review the basic results for hybrid quantum-classical algorithms and quantum error mitigation techniques. Since quantum computing with NISQ devices is an actively developing field, we expect this review to be a useful basis for future studies.
Molecular characterization of cisgenic lines of apple ‘Gala’ carrying the <i>Rvi6</i> scab resistance gene (2013)

Using resistance genes from a crossable donor to obtain cultivars resistant to diseases and the use of such cultivars in production appears an economically and environmentally advantageous approach. In apple, introgression of resistance genes by classical breeding results in new cultivars, while introducing cisgenes by biotechnological methods maintains the original cultivar characteristics. Recently, plants of the popular apple 'Gala' were genetically modified by inserting the apple scab resistance gene Rvi6 (formerly HcrVf2) under control of its own regulatory sequences. This gene is derived from the scab-resistant apple 'Florina' (originally from the wild apple accession Malus floribunda 821). The vector used for genetic modification allowed a postselection marker gene elimination to achieve cisgenesis. In this work, three cisgenic lines were analysed to assess copy number, integration site, expression level and resistance to apple scab. For two of these lines, a single insertion was observed and, despite a very low expression of 0.07- and 0.002-fold compared with the natural expression of 'Florina', this was sufficient to induce plant reaction and reduce fungal growth by 80% compared with the scab-susceptible 'Gala'. Similar results for resistance and expression analysis were obtained also for the third line, although it was impossible to determine the copy number and TDNA integration site-such molecular characterization is requested by the (EC) Regulation No. 1829/2003, but may become unnecessary if cisgenic crops become exempt from GMO regulation.
Nuclear DNA Content of Perennial Grasses of the Triticeae (1999)

Nuclear DNA content was determined by flow cytometry for an array of perennial species of the Triticeae (Poaceae) which characterize the tribe and are representative of the genomes of the Triticeae. The mean nuclear DNA content expressed on a diploid basis (DNA pg/2C) for the diploid genomes (in parentheses) were as follows: Agropyron (PP) 13.9 pg, Pseudoroegneria (StSt) 8.8 pg, Hordeum (HH) 9.5 pg, Psathyrostachys (NsNs) 16.7 pg, and Thinopyrum genomes (E b E b ) 14.9 pg and (E e E e ) 12.0 pg. The YY genome in Elymus was determined by difference to be 9.3 pg. The unknown or XmXm genome or genomes in Leymus could have DNA contents that range from 2.7 to 7.7 pg/2C. There were significant differences in DNA content of species with similar diploid genomes. There were also significant differences in nuclear DNA content among polyploid species with the same genomes. In general, the nuclear DNA content of the polyploid species of the Triticeae were similar to the expected DNA contents on the basis of previous genomic classifications. However, in some allopolyploid genera such as Thinopyrum and Pascopyrum , the nuclear DNA content of some species was less than expected on the basis of summation of the DNA of constituent genomes. The results indicate that gain or loss of nuclear DNA has occurred during the evolution of the perennial Triticeae and was probably a part of speciation.
Theory of polarization of crystalline solids (1993)

We consider the change in polarization \ensuremath{\Delta}P which occurs upon making an adiabatic change in the Kohn-Sham Hamiltonian of the solid. A simple expression for \ensuremath{\Delta}P is derived in terms of the valence-band wave functions of the initial and final Hamiltonians. We show that physically \ensuremath{\Delta}P can be interpreted as a displacement of the center of charge of the Wannier functions. The formulation is successfully applied to compute the piezoelectric tensor of GaAs in a first-principles pseudopotential calculation.
Differential Expression of MicroRNAs During Allograft Rejection (2012)

MicrorRNA are small noncoding RNA molecules that regulate the posttranscriptional expression of target genes. In addition to being involved in many biologic processes, microRNAs are important regulators in innate and adaptive immune responses. Distinct sets of expressed microRNAs are found in different cell types and tissues and aberrant expression of microRNAs is associated with many disease states. MicroRNA expression was examined in a model of heterotopic heart transplantation by microarray analyses and a unique profile was detected in rejecting allogeneic transplants (BALB/c → C57BL/6) as compared to syngeneic transplants (C57BL/6 → C57BL/6). The microRNA miR-182 was significantly increased in rejecting cardiac allografts and in mononuclear cells that infiltrate the grafts. Forkhead box (FOX) proteins are a family of important transcription factors and FOXO1 is a target of miR-182. As miR-182 increases after transplant, there is a concomitant posttranscriptional decrease in FOXO1 expression in heart allografts that is localized to both the cardiomyocytes and CD3(+) T cells. The microRNA miR-182 is significantly increased in both peripheral blood mononuclear cells and plasma during graft rejection suggesting potential as a biomarker of graft status. Our results identify microRNAs that may regulate alloimmune responses and graft outcomes.
Isolation of the Feline α1,3‐Galactosyltransferase Gene, Expression in Transfected Human Cells and its Phylogenetic Analysis (2005)

The enzyme alpha 1,3-galactosyltransferase (alpha1,3-GT), which catalyzes synthesis of terminal alpha-galactosyl epitopes (Gal alpha1,3Gal beta1-4GlcNAc-R), is produced in non-primate mammals, prosimians and new-world monkeys, but not in old-world monkeys, apes and humans. We cloned and sequenced a cDNA that contains the coding sequence of the feline alpha1,3-GT gene. Flow cytometric analysis demonstrated that the alpha-galactosyl epitope was expressed on the surface of a human cell line transduced with an expression vector containing this cDNA, and this alpha-galactosyl epitope expression subsided by alpha-galactosidase treatment. The open reading frame of the feline alpha1,3-GT cDNA is 1,113 base pairs in length and encodes 371 amino acids. The nucleotide sequence and its deduced amino acid sequence of the feline alpha1,3-GT gene are 88-90% and 85-87%, respectively, similar to the reported sequences of the bovine, porcine, marmoset and cebus monkey alpha1,3-GT genes, while they are 88% and 82-83%, respectively, similar to those of the orangutan and human alpha1,3-GT pseudogenes, and 81% and 77%, respectively, similar to the murine alpha1,3-GT gene. Thus, the alpha1,3-GT genes and pseudogenes of mammals are highly similar. Ratios of non-synonymous nucleotide changes among the primate pseudogenes as well as the primate genes are still higher than the ratios of non-primates, suggesting that the primate alpha1,3-GT genes tend to be divergent.
Gastrointestinal angiodysplasia and bleeding in von Willebrand disease (2014)

Von Willebrand disease (VWD), the most common genetic bleeding disorder, is characterised by a quantitative or qualitative defect of von Willebrand factor (VWF). Patients with VWD suffer from mucocutaneous bleeding, of severity usually proportional to the degree of VWF defect. In particular, gastrointestinal bleeding associated with angiodysplasia is often a severe symptom of difficult management. This review focuses on the pathophysiology, diagnosis and treatment of VWD-associated gastrointestinal angiodysplasia and related bleeding.
Design and Integration of All-Silicon Fiber-Optic Receivers for Multi-Gigabit Chip-to-Chip Links (2006)

This paper presents a top-down approach to the design of all-silicon CMOS-based fully integrated optical receivers. From the system-level requirements, we determine the optimum block-level specifications, based on which the individual building blocks are designed. Measurement results of the manufactured design show operation at data rates exceeding 2.5-Gbps/channel for the detector, the amplification and the clock and data recovery circuits. This proof of concept is the first step towards design optimized, completely integrated, multi-channel optical receivers for high-bandwidth short-distance chip-to-chip interconnects
NBTI aware workload balancing in multi-core systems (2009)

As device feature size continues to shrink, reliability becomes a severe issue due to process variation, particle-induced transient errors, and transistor wear-out/stress such as Negative Bias Temperature Instability (NBTI). Unless this problem is addressed, chip multi-processor (CMP) systems face low yields and short mean-time-to-failure (MTTF). This paper proposes a new design framework for multi-core system that includes device wear-out impact. Based on device fractional NBTI model, we propose a new NBTI aware system workload model, and develop new dynamic tile partition (DTP) algorithm to balance workload among active cores while relaxing stressed ones. Experimental results on 64 cores show that by allowing a small number of cores (around 10%)to relax in a short time period (10 second), the proposed methodology improves CMP system yield. We use the percentage of core failure to represent the yield improvement. The new strategy improves the core failure number by 20 %, and extend MTTF by 30% with little degradation in performance (less than 6%).
