Titles of Scientific Letters in Astrophysics (2000- 2015): A Diachronic Study of Type Distribution and the Relationship Between Title Length and Collaboration Issues

This paper examines how some linguistic and extra-linguistic features of scientific letters published in well-reputed journals in the field of astrophysics (types and length of titles, as well as the relationship between title length and authorship patterns and collaboration practices) have changed over time. Our main results may be summarized as follows: 1) simple and nominal titles significantly outweigh compound, question and verbal titles, although the latter are on the rise; 2) the colon is the most frequently used punctuation mark; 3) the frequency of appearance of colons, full stops and commas increases over time; 4) there is a steady upward trend in longer titles, number of authors and countries; 5) Although over time authors contribute fewer words and countries involved in the research provide more words to the writing of scientific letter titles, authorship variations seem to be more relevant in relationship to the evolution of title length, i.e. title length is more author-driven than country-driven. A final diachronic cross-journal analysis confirms the co-existence of two different collaboration scenarios as already disclosed in a previous synchronic study on the same topic.
Design of Chimeric Alphaviruses with a Programmed, Attenuated, Cell Type-Restricted Phenotype

ABSTRACT The Alphavirus genus in the Togaviridae family contains a number of human and animal pathogens. The importance of alphaviruses has been strongly underappreciated; however, epidemics of chikungunya virus (CHIKV), causing millions of cases of severe and often persistent arthritis in the Indian subcontinent, have raised their profile in recent years. In spite of a continuous public health threat, to date no licensed vaccines have been developed for alphavirus infections. In this study, we have applied an accumulated knowledge about the mechanism of alphavirus replication and protein function in virus-host interactions to introduce a new approach in designing attenuated alphaviruses. These variants were constructed from genes derived from different, geographically isolated viruses. The resulting viable variants encoded CHIKV envelope and, in contrast to naturally circulating viruses, lacked the important contributors to viral pathogenesis: genes encoding proteins functioning in inhibition of cellular transcription and downregulation of the cellular antiviral response. To make these viruses incapable of transmission by mosquito vectors and to differentially regulate expression of viral structural proteins, their replication was made dependent on the internal ribosome entry sites, derived from other positive-polarity RNA (RNA+) viruses. The rational design of the genomes was complemented by selection procedures, which adapted viruses to replication in tissue culture and produced variants which (i) demonstrated different levels of replication and production of the individual structural proteins, (ii) efficiently induced the antiviral response in infected cells, (iii) were incapable of replication in cells of mosquito origin, and (iv) efficiently replicated in Vero cells. This modular approach to genome design is applicable for the construction of other alphaviruses with a programmed, irreversibly attenuated phenotype.
Low-power integrated CMOS RF transceiver circuits for short-range applications

This paper discusses our efforts in designing different low-power RF transceiver blocks, starting with the LNA and power amplifier (PA). The paper discusses the effect of four different input matching methodologies on the gain of narrow-band LNAs. Measurement results of two LNAs fabricated in a 0.18 mum CMOS technology are also presented. Two ultra-wideband (UWB) LNA designs that aim for low- voltage and low-power operation are also discussed in this paper. The UWB LNAs consume a power of 5.8 mW from a 0.8 V supply voltage, while achieving a maximum gain of 12.5 dB and an input matching better than -10 dB from 2-10 GHz with a NF of 3.5 dB. A fully integrated, 2.4 GHz class-E PA, with a class-F driver stage is also discussed in this work, demonstrating the feasibility of using CMOS class-E PAs for low-transmit power applications. The circuit was fabricated in a standard 0.18 mum CMOS technology with a maximum drain efficiency of 53%. When operating from a 1.2 V supply, the PA delivers an output power of 14.5 mW with a power-added efficiency (PAE) of 51%. The supply voltage can go down to 0.6 V with an output power of 3.5 mW and a PAE of 43%. Finally, the paper also discusses a simple transmitter and receiver front-end, in addition to a single-block simplified, low- power PLL transmitter design.
Non-Unitary Matrix Based Differential Phase Control Codebook for Temporally Correlated Channels

In this paper, we propose an adaptive differential phase control codebook for limited feedback system in slowly time varying channels. In limited feedback system, channel state information is quantized with a given codebook. The spherical cap can be considered as the coverage of a given codebook where the overall channel space is multi-dimensional sphere. By changing the spherical cap radius properly according to the channel statistics, the proposed codebook design scheme can generate the codebook online to track the channel well. The spherical cap radius is analyzed mathematically in this paper. Monte-Carlo simulations demonstrate that the achievable throughput performance employing the proposed codebook is always superior to those of the non-adaptive differential codebooks with the same amount of feedback information.
Using DistribUteD representations for aspect-baseD sentiment analysis

The article is focused on aspect-based sentiment analysis, which is a specific version of the general sentiment analysis task. Its goal is to detect the opinions expressed in the text on the level of significant aspects of the specified entity. An overview of the existing approaches and previous work is presented. The main result of our work is a new method of aspect-based sentiment analysis based on the distributed representations of words. Such representations are obtained by using deep learning algorithms. The method includes the well-known algorithm of training distributed representations of words, two new techniques for constructing the aspect and sentiment lexicons, and an algorithm for calculating aspect scores. Examples of aspect and sentiment terms are given. The vectors of resulting terms are visualized using the t-SNE method. The article presents the results of experiments on a test corpus for three aspects—“food”, “interior” and “service”, which yield aF1-measure increase of 11 to 16% as compared to the baseline.
THE EFFECT OF IMMUNOSUPPRESSION AGENTS ON STEM AND ENDOTHELIAL CELLS' PROLIFERATION IN VITRO

The control of immune-mediated transplant rejection by immunosuppressive agents might affect other human cells’ proliferation and function. This study aims to evaluate the effect of three immunosuppressants on the proliferation of human adipose-derived adult stroma (ADAS) and human umbilical vein endothelial cells (HUVEC). These cells were used as a culture model to study the minimum inhibitory dose of commonly used immunosuppressants. Cells were cultured and seeded into 96-well plates at a density of 2,500/well then treated either with one of two calcineurin inhibitors, namely FK506 (Tacrolimus) and Cyclosporin A (CsA), or with the IMP dehydrogenase inhibitor, Mycophenolic acid (MPA). After 5 days, the medium was removed and plates were stored at −70°C until analyzed with the CyQUANT cell proliferation assay. The minimum inhibitory dose on HUVEC proliferation was 1000 ng/ml for CsA, 500 ng/ml for MPA, and 10,000 ng/ml for FK506. The minimum inhibitory dose on ADAS proliferation was 5 ng/ml for MPA, 100000 ng/ml for FK506 and 100000 ng/ml for CsA. Our results suggest that these immunosuppressants inhibit ADAS and HUVEC proliferation in a dose-dependent manner in vitro. The FK506 and CsA minimum inhibitory concentrations on both HUVEC and ADAS were several orders of magnitude greater than those required for T cell inhibition and, therefore, regular dosages are not expected to impair HUVEC or ADAS proliferation. However, the minimum inhibitory concentration of MPA on ADAS was lower than that observed in vitro for lymphocyte function and, therefore, could be of concern.

A Power Control Method With Simple Structure and Fast Dynamic Response for Single-Phase Grid-Connected DG Systems

This paper presents a new method for controlling the exchange of power between a single-phase distributed generation system and the grid. Rather than controlling the active and reactive powers separately and through the media of current signal as is done by the conventional techniques, the proposed controller acts directly on the instantaneous power. This eliminates the conventional need for calculating the active and reactive powers; a calculation that involves filtering/phase-shifting and slows down the system responses and adds to computational complexity. This paper first formulates a nonlinear structure from a purely mathematical approach based on minimizing a cost function. The minimization procedure generates a reference for the current signal which is subsequently used in the current control loop. This paper then derives an equivalent linear counterpart for the nonlinear structure. Moreover, it is also shown that the idea of controlling the instantaneous power does not require a separate loop for the current. Having replaced the nonlinear part with its linear equivalent, a control loop that comprises linear time-varying elements is obtained. This paper further develops a linear time-invariant model of the loop for stability and design purposes. The proposed control system is successfully applied to a photovoltaic system and performance evaluation results (using computer simulations and a laboratory experimental setup) are presented. Desired performance and robustness of the proposed method is verified by testing it within different operating conditions.
Solutions for Enabling Communication between Different Proprietary Peer-to-peer Systems

The Streaming traffic is one of the fastest growing traffic on the internet. Although the streaming traffic is growing fast, the peer-to-peer systems have solved this problem as its scalability and its fault tolerance against failures of centralized infrastructures. But because of the enormous growth in the number of peer-topeer applications in recent years, they have occupied the most bandwidth of the internet, and it’s essential to integrate them into the global content delivery infrastructure. In this paper, we propose two solutions for communicating between different proprietary peer-to-peer systems. One solution is to add a logical layer for enabling the communications between the existing peer-to-peer systems, while the other one is a service-oriented architecture by using the integrated network storage.
The quest for four-dimensional imaging in plant cell biology: it's just a matter of time.

BACKGROUND Analysis of plant cell dynamics over time, or four-dimensional imaging (4-DI), represents a major goal of plant science. The ability to resolve structures in the third dimension within the cell or tissue during developmental events or in response to environmental or experimental stresses (i.e. 4-DI) is critical to our understanding of gene expression, post-expression modulations of macromolecules and sub-cellular system interactions. SCOPE Microscopy-based technologies have been profoundly integral to this type of investigation, and new and refined microscopy technologies now allow for the visualization of cell dynamics with unprecedented resolution, contrast and experimental versatility. However, certain realities of light and electron microscopy, choice of specimen and specimen preparation techniques limit the scope of readily attaining 4-DI. Today, the plant microscopist must use a combinatorial strategy whereby multiple microscopy-based investigations are used. Modern fluorescence, confocal laser scanning, transmission electron and scanning electron microscopy provide effective conduits for synthesizing data detailing live cell dynamics and highly resolved snapshots of specific cell structures that will ultimately lead to 4-DI. This review provides a synopsis of such technologies available.
A Non-Contact Submillimeter-Wave  $S$-Parameters Measurement Technique for Multiport Micromachined Devices

This paper presents a novel non-contact broadband on-wafer S-parameter measurement technique for submillimeter-wave and terahertz applications. The proposed method enables S-parameters measurement of multi-port micromachined devices using a two-port measurement setup. In this method, a small fraction of the signal at each waveguide port is weakly coupled to free space using a small array of reflection-canceling slots which are then measured by an open-ended waveguide probe. The S-parameters of the device-under-test are calculated from the measured signals obtained from each port and from that of a reference match waveguide. A broadband waveguide slot array antenna with high return loss is designed as a matched load to terminate all ports of the device except the input port. To assess the reliability and accuracy of the proposed measurement method, three different micromachined waveguide directional couplers are designed, fabricated, and tested. Multiple apertures on the common wall between the adjacent waveguides are designed and optimized to achieve high directivity couplers over a broad frequency range. The measured S-parameters of the couplers are shown to be in good agreement with the simulations, which indicates the accuracy of the proposed measurement method.
Pathways to enhanced value creation from the international technology transfer process in Thai construction projects

Purpose – International technology transfer (TT) initiatives are essential for developing the necessary infrastructure which underpins the sustainable development of economics and living standards in newly industrialised and developing countries. However, these initiatives have rarely translated into enhanced capabilities and competitiveness within host country firms, resulting in a sustained reliance on foreign firms. With few clues as to how to effectively manage the TT process, many stakeholders from the construction sectors of developing countries lack direction on how to more rapidly diffuse best‐practice technology. This paper aims to address the issues.Design/methodology/approach – In an attempt to better understand, the international TT process on Thai construction projects a path model was developed and later implemented. The path model development stage utilised the questionnaire survey response of 162 Thai construction and engineering professionals that had exposure to construction projects whi.
Confocal microscopy study of donor–recipient interface after Descemet's stripping with endothelial keratoplasty

Aim To evaluate the in vivo confocal microscopic corneal features seen in patients who underwent Descemet's stripping with endothelial keratoplasty (DSEK) and to correlate these findings with the postoperative best spectacle-corrected visual acuity (BSCVA) obtained at the time of confocal microscopy. Methods Observational case series. A review of charts and confocal microscopy images and videos (Confoscan 4; Nidek Technologies America, Greensboro, North Carolina, USA) of 25 consecutive eyes from 21 patients who underwent DSEK for Fuchs' dystrophy or pseudophakic bullous keratopathy and had a follow-up of at least 6 months post-DSEK. Time from DSEK to confocal microscopy ranged from 6 to 22 months. Subepithelial haze, donor–recipient interface haze, interface birefringent particles and presence of stromal folds were evaluated by a blinded observer and correlated to the postoperative BSCVA. Results 25 eyes (21 patients) with a mean age of 71.3 (11.8) years were included. A significant negative correlation was found between postoperative BSCVA and subepithelial corneal haze (Spearman correlation coefficient) (rs=−0.651; p=0.0004). Donor–recipient interface haze (rs=−0.0908; p=0.6658), interface particles (rs=−0.2403; p=0.2472) or the presence of stromal folds (rs=0.111; p=0.6055) did not correlate with BSCVA. Conclusion Subepithelial haze, donor–recipient stromal interface haze, birefringent particles and stromal folds were present at different degrees in all patients who underwent DSEK. However, subepithelial haze was the only factor that correlated to postoperative BSCVA.
Potential misidentification of Burkholderia pseudomallei by API 20NE

Summary Biochemical confirmation of the identity of Burkholderia pseudomallei in Singapore previously relied on the API 20NE panel of tests. After introducing an alternative proprietary biochemical panel, the Microbact 24E (MedVet, Adelaide, Australia), we noted that the API panel identified some presumptive B. pseudomallei isolates as other species. We therefore compared the performance of the API 20NE against the Microbact 24E with 50 distinct clinical isolates of B. pseudomallei, after 24 hours and after five days incubation of primary cultures. The API panel correctly identified 40 isolates. Four results were unacceptable or uninterpretable. Six isolates were misidentified as other species; the commonest being Chromobacterium violaceum. One of these was again identified as C. violaceum by the repeat API panel. Fourteen isolates, including the six misidentified isolates and four isolate pairs from separate sources in four separate patients, were typed using PCR amplification of repetitive extragenic palindromic sequences (REPS). The isolates identified as C. violaceum appeared to have identical REPS patterns, suggesting that some of the errant API results may be due to a single locally prevalent strain of B. pseudomallei. A previous suggestion that C. violaceum may produce a melioidosis-like illness may therefore be due to laboratory misidentification of B. pseudomallei with the API 20NE biochemical test panel.Abbreviations: REPS, repetitive extragenic palindromic sequences.
Terracotta Figures, Figurines, and Plaques from the Anavlochos, Crete.

In the summer of 2017 two votive deposits were excavated on the summit of the Anavlochos, Crete. The first one yielded protogeometric to classical figures, figurines, and plaques representing female figures. The second one included zoomorphic figures and figurines associated with Late Minoan IIIC pottery. In addition, the head of a female figure was recovered from a shrine that was brought to light on the slope of Kako Plai, just above a third votive deposit, that already had been excavated by Pierre Demargne in 1929.
A Non-Orthogonal Multiple-Access Scheme Using Reliable Physical-Layer Network Coding and Cascade-Computation Decoding

This paper studies non-orthogonal transmission over a <inline-formula> <tex-math notation="LaTeX">$K$ </tex-math></inline-formula><italic>-user</italic> fading multiple access channel. We propose a new reliable physical-layer network coding and cascade-computation decoding scheme. In the proposed scheme, <inline-formula> <tex-math notation="LaTeX">$K$ </tex-math></inline-formula> single-antenna users encode their messages by the same practical channel code and QAM modulation, and transmit simultaneously. The receiver chooses <inline-formula> <tex-math notation="LaTeX">$K$ </tex-math></inline-formula> linear coefficient vectors and <italic>computes</italic> the associated <inline-formula> <tex-math notation="LaTeX">$K$ </tex-math></inline-formula> layers of finite-field linear message combinations in a <italic>cascade</italic> manner. Finally, the <inline-formula> <tex-math notation="LaTeX">$K$ </tex-math></inline-formula> users’ messages are <italic>recovered</italic> by solving the <inline-formula> <tex-math notation="LaTeX">$K$ </tex-math></inline-formula> linear equations. The proposed can be regarded as a generalized onion peeling. We study the optimal network coding coefficient vectors used in the cascade computation. Numerical results show the performance of the proposed approaches that of the iterative maximum <inline-formula> <tex-math notation="LaTeX">$a~posteriori$ </tex-math></inline-formula> probability detection and decoding scheme, but without using receiver iteration. This results in considerable complexity reduction, processing delay, and easier implementation. Our proposed scheme significantly outperforms the iterative detection and decoding scheme with a single iteration, for example, by 1.7 dB for the two user case. The proposed scheme provides a competitive solution for non-orthogonal multiple access.
Niridazole Biodegradable Inserts for Local Long-Term Treatment of Periodontitis: Possible New Life for an Orphan Drug

Periodontal pocket inserts of niridazole (NZ) made with Resomer® (grades RG 503H and RG858, designated as RH and RG, respectively) were studied. Various formulation variables were evaluated to obtain a biodegradable delivery systems showing device degradation and drug depletion parallel to each other in vitro. Drug release from the prepared inserts was evaluated using a static dissolution setup (for 1 month). Incorporation of 3 parts of RG in 1 part of RH inserts caused a 50% decrease in the initial release rate. The RH-NZ inserts showed a spurt in release around the 10th day of the study, which coincided with the decrease in device weight, suggesting onset of device degradation. Pilot-scale clinical trials in 12 patients indicated improvements in clinical indices from the baseline values. The average pocket depth was reduced significantly (α = 0.05) from 6.34 ± 1.86 mm at baseline to 5.94 ± 0.28 mm after 28 days of treatment.
Diurnal rhythms in psychological reward functioning in healthy young men: ‘Wanting’, liking, and learning

ABSTRACT A range of evidence suggests that human reward functioning is partly driven by the endogenous circadian system, generating 24-hour rhythms in behavioural measures of reward activation. Reward functioning is multifaceted but literature to date is largely limited to measures of self-reported positive mood states. The aim of this study was to advance the field by testing for hypothesised diurnal variation in previously unexplored components of psychological reward: ‘wanting’, liking, and learning using subjective and behavioural measures. Risky decision making (automatic Balloon Analogue Risk Task), affective responsivity to positive images (International Affective Pictures System), uncued self-reported discrete emotions, and learning-contingent reward (Iowa Gambling Task) were measured at 10.00 hours, 14.00 hours, and 19.00 hours in a counterbalanced repeated measures design with 50 healthy male participants (aged 18–30). As hypothesised, risky decision making (unconscious ‘wanting’) and ratings of arousal towards positive images (conscious wanting) exhibited a diurnal waveform with indices highest at 14.00 hours. No diurnal rhythm was observed for liking (pleasure ratings to positive images, discrete uncued positive emotions) or in a learning-contingent reward task. Findings reaffirm that diurnal variation in human reward functioning is most pronounced in the motivational ‘wanting’ components of reward.
PCR-Oligonucleotide Ligation Assay from Dried Blood Spots

process, and they work together to effect the amniochorionic system that is the main source for production not only of IL-8 (13 ) but also of various prostanoids (14, 15). Therefore, the highly variable concentrations of IL-8 in the CVS may be attributable to the extent of and/or the stages in which these factors contribute to cervical-decidualamniochorionic activation. However, the precise mechanism is to be investigated further. Moreover, the kinds of signals involved in increasing active Cp in CVS need to be better understood.
