Linearity Characteristics of Avalanche Photodiodes For InP Based PICs

We demonstrate InP PICs with avalanche photodiodes (APD) consisting of InP and InAlAs multiplication regions and investigate these devices regarding their DC and RF linearity characteristics. The optical input dependent gain, bandwidth and output power are characterized and compared to electric field simulations. The space-charge induced electric field reduction is considered to determine the measured properties of the APDs. The APDs with an InAlAs multiplication region exhibit a high bandwidth of 27 GHz in combination with high sensitivity for optical input powers low as 34 µW at a responsivity of 0.65 A/W and a dynamic range of 34 dB. Although the APD with an InP multiplication region shows lower bandwidths of maximum 6 GHz, it demonstrates a high sensitivity for input powers low as 26 µW at a responsivity of 0.85 A/W and a dynamic range of 30 dB making it very attractive for sensing applications. Further, the bias and optical input dependent electric field help to conclude the linearity limitations of the presented devices.
Biotic and abiotic factors control the geomorphic characteristics of channel networks in salt marshes

Biotic and abiotic processes control the formation and evolution of tidal channel networks. However, which factor regulates the planimetric geometry of the network remains unclear. Here, we compare the geometric properties of tidal channel networks in 14 salt marshes along the coasts of the United States and China. Significant difference in the geometric properties of tidal channel networks was found in salt marshes dominated by different vegetation species. Physical parameters better explained these differences, while vegetation parameters had a weaker effect on the network geometry. Mean marsh elevation and tidal range were found to be the best variables to explain the variability in drainage density, mean unchanneled path length and sinuosity (R2 values range from 0.239 to 0.465), while biotic parameters (i.e., aboveground biomass, stem density, height, and diameter) were only significant predictors for less geometric properties (R2 values range from 0.005 to 0.312). We used multiple regressions to develop sample models, explaining more than 60% of the variability in mean unchanneled path length. Our findings underline the key role of physical factors in shaping tidal channel networks. We conclude that physical processes are more important than vegetation species in determining the long‐term development of tidal channels.
Capital Structure and Firm Performance of Technology Sector in Malaysia

The purpose of this study is to investigate the relationship between capital structure and firm performance of technology sector in Malaysia. The 27 public listed software companies in Bursa Malaysia are examined within the time period of 8 years from 2012 to 2019, with the total observation of 216. The data is focusing in one sub-sector of technology sector which is software sector. The study is conducted with two firm performance measures which are return on asset (ROA) and return on equity (ROE). Total debts to total assets (TDTA), long-term debt to total assets (LTDTA), and short-term debt to total assets (STDTA) are the proxies of capital structure while growth (GRO) is the control variable. Panel data regression model is used in this study and found that that long-term debt to total assets (LTDTA) and short-term debt to total assets (STDTA) have a negative significant relationship with return on equity (ROE) while total debt to total assets (TDTA) has a positive significant effect on return on equity (ROE). However, in return on assets (ROA), only short-term debt to total assets (STDTA) has a negative significant on it, while the other independent variables are insignificant. Lastly, there is a positive significant relationship between growth (GRO) and performance of a company.
Optimization of the geometry of electrostatic micromotors using only analytical equations

Since electrostatic motors require very high voltages and do not exert great efforts on the usual dimensional scale, their design and optimization are not well known, but on the millimetre and micrometre scales, this kind of motor seems to present interesting qualities. The optimization of electrostatic micromotors is generally based on the use of numerical finite-element methods. Because of the numerous possible geometrical combinations, this type of optimization takes a lot of time and must be reperformed for each application. In this paper, we present the optimization of variable capacitance motors based solely on an analytical model of the stator - rotor capacity. For each application, this model allows determination of the optimal geometrical dimensions of the electrostatic micromotor depending on the fabrication process used.

Three patients with diabetic ulcers have been selected and applied Growth factors-rich plasma and membrane treatment on weekly basis and analyzed the results. Results: Growth factors-rich plasma injection and membrane application on wound have produced remarkable wound healing outcome within 3 to 6 applications with new vascularization and re-epithelialization. Conclusion: Growth factors-rich plasma and membrane application on wound gained favor as a wound-healing therapy due to its constituents which have remarkable potential to speed up the injured tissue repair and regeneration. The release of cytokines with platelet-derived growth molecules enveloped in alpha-granule, promote & facilitate wound healing.
An Interior-Point Solver for AC Optimal Power Flow Considering Variable Impedance-Based FACTS Devices

This work proposes a full AC optimal power flow (ACOPF) model considering variable impedance-based flexible AC transmission system (FACTS) devices, in which the reactance of lines are introduced as decision variables to minimize system operation costs, power losses, and load shedding costs. This work is motivated by increasing interest in using FACTS and Distributed FACTS (D-FACTS) devices to address system operational and cyber-security concerns in the presence of renewable energy, such as line congestion relief, power loss reduction, load curtailment reduction, and moving target defense. The proposed ACOPF model can be utilized by system operators to achieve economic and cyber-security benefits simultaneously. In addition, we build and make publicly available an open-source MATPOWER-based interior-point solver for the proposed ACOPF model through rigorously deriving the gradient and Hessian matrices of the objective function and constraints. Numerical results on an IEEE 118-bus transmission system and an IEEE 69-bus distribution system show the validity of the proposed ACOPF model as well as the efficacy of the developed interior-point solver.

What Will They Think If I Post This? Risks and Returns for Political Expression Across Platforms

Social networking sites (SNSs) allow individuals to establish and maintain a variety of relationships as well as share different aspects of their identity by expressing their views on numerous topics, including politics. SNS also come with perceived interpersonal risks and benefits tied to sharing with a collapsed networked audience. Using a nationally representative sample of US social media users (N = 2,873) from 2016, this study investigated how perceived network characteristics influence people’s decision to engage in online political expression on three platforms: Facebook, Twitter, and Instagram. Findings indicate that perceived ideological homophily with the audience on an SNS and past use of privacy management settings both predict how much individuals post about politics on Facebook and Twitter, but not on Instagram. On Instagram, Black Americans were significantly more likely to engage in online political expression. On Facebook and Twitter, older Americans engaged in more political expression, and across all platforms, perceptions that political discussion online is uncivil were negatively associated with political expression.

Analysis of Simian Endogenous Retrovirus (SERV) proviruses in Old World Monkey Genomes: Evidence for a Transition to Replication during Embryogenesis

Simian endogenous retrovirus, SERV, is a successful germ line invader restricted to Old World monkey (OWM) species. (1) Background: The availability of high quality primate genomes warrants a study of the characteristics, evolution and distribution of SERV proviruses; (2) Methods: Cercopithecinae OWM genomes from public databases were queried for the presence of full length SERV proviruses. A dataset of 81 Cer-SERV genomes was generated and analyzed; (3) Results: Full length Cer-SERV proviruses were mainly found in terrestrial OWM, and less so in arboreal, forest- dwelling monkeys. Phylogenetic analysis confirmed the existence of two genotypes, Cer-SERV-1 and Cer-SERV-2, with Cer-SERV-1 showing evidence of recent germ line expansions. Long Terminal Repeat (LTR) variation indicated that most proviruses were of a similar age, and were estimated to be between &lt;0.3 and 10 million years old. Integrations shared between species were relatively rare. Sequence analysis further showed extensive CpG methylation-associated mutation, variable Primer Binding Site (PBS) use with Cer-SERV-1 using PBSlys3 and Cer-SERV-2 using PBSlys1,2, and the recent gain of LTR motifs for transcription factors active during embryogenesis in Cer-SERV-1; (4) Conclusions: sequence analysis of 81 SERV proviruses from Cercopithecinae OWM genomes provides evidence for the adaptation of this retrovirus to germ line reproduction.
Aerodynamic optimization of wind turbine rotors using a blade element momentum method with corrections for wake rotation and expansion

The blade element momentum (BEM) method is widely used for calculating the quasi-steady aerodynamics of horizontal axis wind turbines. Recently, the BEM method has been expanded to include corrections for wake expansion and the pressure due to wake rotation (BEMcor), and more accurate solutions can now be obtained in the blade root and tip sections. It is expected that this will lead to small changes in optimum blade designs. In this work, BEMcor has been implemented, and the spanwise load distribution has been optimized to find the highest possible power production. For comparison, optimizations have been carried out using BEM as well. Validation of BEMcor shows good agreement with the flow calculated using an advanced actuator disk method. The maximum power was found at a tip speed ratio of 7 using BEMcor, and this is lower than the optimum tip speed ratio of 8 found for BEM. The difference is primarily caused by the positive effect of wake rotation, which locally causes the efficiency to exceed the Betz limit. Wake expansion has a negative effect, which is most important at high tip speed ratios. It was further found that by using BEMcor, it is possible to obtain a 5% reduction in flap bending moment when compared with BEM. In short, BEMcor allows fast aerodynamic calculations and optimizations with a much higher degree of accuracy than the traditional BEM model. Copyright © 2011 John Wiley & Sons, Ltd.
Prestressed near-surface mounted fibre reinforced polymer reinforcement for concrete structures — a review1

The specialized application of prestressing the near-surface mounted (NSM) fibre reinforced polymer (FRP) reinforcement for strengthening reinforced concrete (RC) structures combines the benefits of the FRP reinforcement with the advantages associated with external prestressing. By applying a prestress to the NSM FRP the material is used more efficiently since a greater portion of its tensile capacity is employed. This paper presents a comprehensive review on the performance of RC members strengthened using prestressed NSM FRP reinforcement. Several techniques and anchorage systems developed to prestress the NSM FRP are presented. The static flexural and fatigue performance of RC beams strengthened using prestressed NSM FRP in comparison to non-prestressed NSM is presented. Research on the long-term performance under freeze–thaw exposures and sustained loading is also presented.
Emergency remote teaching and learning in simultaneous interpreting: Capturing experiences of teachers and students

The article covers the transfer to emergency remote teaching and learning in Simultaneous Interpreting (SI) during the Covid-19 pandemic and the lockdown in early 2020. The study aims to establish some approaches as to how the emergency move to online training was conducted, what we can learn from this experience and what were the main challenges. The article presents and analyses the findings of the survey of teaching staff and students in seven universities in Europe and Australia. Twelve interviews were conducted remotely with selected members of teaching staff and students. The study confirms that universities were able to complete their modules in Simultaneous Interpreting by making arrangements for a smooth transfer to remote training in synchronous and asynchronous modes. The transfer and emergency remote teaching and learning mostly depended on the prior experience of teaching teams in delivering online workshops and webinars and their close engagement with students. The role of course or module leader has been outlined as key to providing leadership during the transfer to emergency arrangements during lockdown. One of the conclusions of this study addresses the need for teaching remote interpreting within university Interpreting or Translation and Interpreting courses in view of the current situation with the Covid-19 pandemic and possible new re-quirements in the future. © Alex Krouglov 2021.

The Role of Ancestral Duplicated Genes in Adaptation to Growth on Lactate, a Non-Fermentable Carbon Source for the Yeast Saccharomyces cerevisiae

The cell central metabolism has been shaped throughout evolutionary times when facing challenges from the availability of resources. In the budding yeast, Saccharomyces cerevisiae, a set of duplicated genes originating from an ancestral whole-genome and several coetaneous small-scale duplication events drive energy transfer through glucose metabolism as the main carbon source either by fermentation or respiration. These duplicates (~a third of the genome) have been dated back to approximately 100 MY, allowing for enough evolutionary time to diverge in both sequence and function. Gene duplication has been proposed as a molecular mechanism of biological innovation, maintaining balance between mutational robustness and evolvability of the system. However, some questions concerning the molecular mechanisms behind duplicated genes transcriptional plasticity and functional divergence remain unresolved. In this work we challenged S. cerevisiae to the use of lactic acid/lactate as the sole carbon source and performed a small adaptive laboratory evolution to this non-fermentative carbon source, determining phenotypic and transcriptomic changes. We observed growth adaptation to acidic stress, by reduction of growth rate and increase in biomass production, while the transcriptomic response was mainly driven by repression of the whole-genome duplicates, those implied in glycolysis and overexpression of ROS response. The contribution of several duplicated pairs to this carbon source switch and acidic stress is also discussed.
Language Dispersal Beyond Farming

Th is chapter presents reconstructed Proto-Quechua and Proto-Aymara lexical items related to cultivation and herding, and draws conclusions about language and subsistence in the ancient Andes. Th e patterns of lexical borrowing between the two lineages o ff er a novel empirical perspective on how early Quechuan and Aymaran speakers lived. When the many layers of borrowing are stripped away, it is clear that both were engaged in agropastoral economies before the languages fi rst came into contact. Furthermore, the presence of terms from a wide range of ecological zones, from the high grasslands to (in the case of Quechua) the tropical lowlands, suggests that both languages cross-cut elevations in a manner consistent with the typically Andean system of ecological complementarity.
Transportation responsiveness and efficiency within the building supply chain

Following the example of the manufacturing industry, the construction industry has utilized supply chain management to improve its performance and competitiveness. However, although performance measurement has attracted particular attention in the sector since the 1990s, supply chain performance measurement has been largely overlooked. Therefore, given that buildings are outputs of supply chain systems, there is a need to develop a better understanding of performance measurement pertaining to the interactions and interdependencies between the constituent parts of these systems. Based on primary data collected through a field study, the performance of two material distribution companies is examined in terms of their capacity to provide a time-responsive and cost-effective service to the building industry. Descriptive and inferential statistics are used to assess performance according to a range of performance indicators and to explore the relationship between transportation responsiveness and cost efficiency. The results show that vehicle-loading efficiency levels are particularly lower than those estimated in other sectors and reveal the prevalence of empty vehicle runs during backhauling. Significant variations in performance between the two companies are observed to be mainly attributable to the nature of business itself, as well as to adopted distribution strategies. Suivant l'exemple du secteur manufacturier, l'industrie du bâtiment a eu recours à la gestion de la chaîne logistique pour améliorer ses performances et sa compétitivité. Bien que la mesure de la performance ait fait l'objet d'une attention particulière dans ce secteur depuis les années 1990, la mesure de la performance de la chaîne logistique a été largement négligée. Etant donné que les bâtiments sont le résultat des systèmes de chaîne logistique, il est donc nécessaire de parvenir à une meilleure compréhension de la mesure de la performance concernant les interactions et les interdépendances entre les éléments constitutifs de ces systèmes. En se basant sur les données primaires recueillies grâce à une étude de terrain, les performances de deux entreprises de distribution de matériaux sont examinées sous l'angle de leur capacité à fournir à l'industrie du bâtiment des prestation réactives et rentables. Des statistiques descriptives et inférentielles sont utilisées pour évaluer leurs performances selon une gamme d'indicateurs de performance et pour étudier la relation entre la réactivité du transport et la rentabilité. Les résultats montrent que les niveaux d'efficacité de chargement des véhicules sont sensiblement inférieurs à ceux estimés dans d'autres secteurs et révèlent la prévalence des trajets à vide des véhicules lors du transport de retour. Il est observé des variations importantes de la performance entre les deux entreprises, qui sont principalement imputables à la nature même de leurs activités, ainsi qu'aux stratégies de distribution adoptées.
