Small-Signal Modeling of the Incremental Optical Encoder for Motor Control

The small-signal model of the incremental optical encoder introduced in this paper provides an insight on the impact of this sensor in the dynamics of the motion control loop of a motor drive. The model is derived and validated for the most commonly employed speed estimation methods: the pulse count and the elapsed time methods. Using the model, the reduction of the phase margin due to the encoder phase lag can be quantified at an early design stage. This model facilitates the design of control techniques to compensate for the phase margin reduction due to the associated feedback delays.
Head-mounted displays and dynamic text presentation to aid reading in macular disease

The majority of individuals living with significant sight loss have residual vision which can be enhanced using low vision aids. Smart glasses and smartphone-based headsets, both increasing in prevalence, are proposed as a low vision aid platform. Three novel tests for measuring the visibility of displays to partially sighted users are described, along with a questionnaire for assessing subjective preference. Most individuals tested, save those with the weakest vision, were able to see and read from both a smart glasses screen and a smartphone screen mounted in a headset. The scheme for biomimetic scrolling, a text presentation strategy which translates natural eye movement into text movement, is described. It is found to enable the normally sighted to read at a rate five times that of continuous scrolling and is faster than rapid serial visual presentation for individuals with macular disease. With text presentation on the smart glasses optimised to the user, individuals with macular disease read on average 65% faster than when using their habitual optical aid. It is concluded that this aid demonstrates clear benefit over the commonly used devices and is thus recommended for further development towards widespread availability.
Types of Situations and Their Event Structure

In the paper the concept of "situation" in a linguistic context is discusses, and is defined as a complex of interrelated events occurring in a particular place and time. The difference between situations and events is explained, thus events are considered as part of the situation. The event structure of the situation is proposed, which includes the composition of its participants (actants) and their role in the interaction that binds them in a given situation, as well as the circonstants. With the help of the frame/script description, a characteristic of such class of situations as a situation of confrontation is proposed. Keywords—semantics; situation; event; actant; frame
Financial Analysis of Photovoltaic Installations in Burkina Faso

This article focuses on the economic and financial calculations concerning the production of electrical energy from photovoltaic installations connected to the grid. The estimation of energy production is done in fifteen cities in Burkina Faso. Among these localities, ten cities are homes to synoptic stations. The economic return in terms of the return on investment of the electricity production from PV installations is calculated by using the method of budgeted capital. The cost of the energy produced by photovoltaic installations during their operational lives (taken here equal to 25 years) is calculated and compared with other economic parameters. The observation shows that Gaoua records the smallest production and that the highest production is recorded in Ouahigouya. The analysis of the cash flows generated by the operation of these PV installations shows that the profits are perceptible from the 8th year in Ouahigouya and the 9th year in Gaoua. An Internal Rate of Return (IRR) of 14.42% is obtained in the locality of Ouahigouya. For locality of Gaoua the IRR is equal to13.72%. The calculation of Leveled Cost Of Energy (LCOE) gives an average value of 60 Fcfa / kWh for a discount rate of 4%. This value is almost equal to half the average price of electricity in Burkina Faso, which is 119 Fcfa / kWh.
Evaluation of Alveolar Bone on Dental Implant Treatment using Cone Beam Computed Tomography

Objective: To observe the outcomes of dental implant treatment based on the evaluation of bone conditions using Cone Beam Computed Tomography (CBCT). Material and Methods: A total of 31 dental implants were collected for the present study. Subsequently, mesial and distal bone losses were examined, while buccal and lingual bone thickness were measured at 7 levels. Evaluation and interpretation of CBCT results was performed by 3 independent examiners. Results: The average of mesial bone loss was 1.08 mm and 1.36 mm on distal bone. Every dental implant had lingual/palatal bone on level 1 to 3, only 1 (6.5%) didn’t have bone on level 4, 3 implants (9.7%) had no bone at level 5 and 6, and 22 implants (74.2%) had no bone at level 7/implant platform. There were 8 implants (25.8%) didn’t have buccal bone at level 7, only 1 implant (3.2%) didn’t have buccal bone at level 2,4,5 and 6, and there were 2 implants (6.5%) had no buccal bone on level 3. Dehiscence / fenestration can be seen on 90% of the implant subjects. Conclusion: These bone loss condition could be consequence of several factors such as infection, diagnosis, treatment plan, and operator’s surgery skills. The implants that placed without CBCT could lead to operator miscalculation on bone condition, therefore in moderate to advanced cases, the use of CBCT should be mandatory for treatment plan.
Conditional Independence Approximation to Cross-media Incremental Reach

An independence assumption has been used as a solution to calculate cross-media ads reach when cross-media panel data are unavailable. In this paper, we introduce restricted conditional independence assumption (RCIA) and apply it to calculate the digital video incremental reach on top of TV. By conducting large-scale simulation studies based on the cross-media universes in a single source panel, we show that RCIA based incremental reach is close to the standard calculation based on the cross-media universes. Moreover, substantial variance reduction is achieved from RCIA with single-media panel data compared to the standard calculation based on the cross-media universes. We use distance correlation to measure the strength of dependence between ad impressions of TV campaigns and digital video. The magnutudes of distance correlation between these two types of ad impressions are small, and only ∼ 2% TV campaigns show statistically signiﬁcant dependence. As a summary, because of its high accuracy, low variance, simplicity and low cost, we recommend that the RCIA approximation as a preferred solution than the standard cross-media universe calculation.
The associativity evaluation between open data and country characteristics

PurposeThe purpose of this study is to review the levels of open government data (OGD) among various countries that are not consistent with the development levels of those countries. This study evaluates the associativity between OGD Index (OGD) and the characteristics of those countries as well as to compare the degree of OGD among countries. Accordingly, an advanced discussion to explore how a country’s characteristics affect how that country’s government opens data was presented.Design/methodology/approachThe stakeholder relationships of OGD is analysed with the characteristics of a country. The usage data are compared with the data availability according to nine indicators. These data collected from the statistics and OGDI websites are grouped for comparative statistical analyses based on basic descriptive statistics, one-way analysis of variance and a regression model with variance inflation faction.FindingsThe results 1) revealed the reasons some countries have high-ranking indexes and 2) verified the high index values of countries in terms of their degrees of development. This study, thus, attempted to derive a balanced appraisal of national development and OGD.Research limitations/implicationsThe study sample is limited only to countries 1) which open the statistical data; and 2) are of uneven population density and development degree. The OGDI is limited to expert evaluation. The score might be vary to experts and users with diverse countries at different evaluation period. The limitations can be attributed to the differences between OGDI and real open levels. These differences might influence the reliability and validity.Practical implicationsGovernment departments with OGD policies provide raw data in various formats and with application interfaces for user access. This study, thus, attempts to derive a balanced appraisal of national development and OGD. The factors that evaluate which types of countries open the level of data are explored.Originality/valueThis study establishes stakeholder relationships of OGD and extends to analyse the characteristics of a country and OGD that affect the government data open level. The relationships are evaluated through the OGDI with design score scheme. The measurement results indicated that a country possesses high relation to open data with high DI and nature resource.
Disinformation, performed: self-presentation of a Russian IRA account on Twitter

ABSTRACT How disinformation campaigns operate and how they fit into the broader social communication environment – which has been described as a ‘disinformation order’ [Bennett & Livingston, (2018). The disinformation order: Disruptive communication and the decline of democratic institutions. European Journal of Communication, 33(2), 122–139] – represent critical, ongoing questions for political communication. We offer a thorough analysis of a highly successful disinformation account run by Russia’s Internet Research Agency: the so-called ‘Jenna Abrams’ account. We analyze Abrams’ tweets and other content such as blogposts with qualitative discourse analysis, assisted by quantitative content analysis and metadata analysis. This yields an in-depth understanding of how the IRA team behind the Abrams account presented this persona across multiple platforms and over time. Especially, we describe the techniques used to perform personal authenticity and cultural competence. The performance of personal authenticity was central to her persona building as a likeable American woman, whereas the performance of cultural competence enabled her to infiltrate American conservative communities with resonant messages. Implications for understanding disinformation processes, and how some aspects of the hybrid media system are especially vulnerable to hijacking by bad actors are discussed.
Winter Birds in a Developing Pine Plantation

Rbsrmcr: Winter resources may limit bird populations. In this study we document the winter bird community and assess habitat relationships in a single large loblolly pine (Pimu I&) plantation (-500 ha) from shortly after establishment into the middk-age closed canopy stage at 16 years. The winter bird community changed as the plantation grass/forb/shrub community gave way to low shrubs, and again as low shrubs were dominated 8nd mostly supplanted by the rapidly growing pine trees The highest bird abundance (436/km’) and the most species (22) occurred the second year after planting (the first year of the study). After the second year post establishment, the number of species declined and bird abundance declined consistently until about year IO when pine canopies dominated. From age IO to I6 years of the plantation, number of bird species was variabk and bird abundances were low and variabk. Bird specks diversity was variabk throughout the study.
Multisensor Imaging System Video Interface Implementation in Fpga

In this paper we describe practical implementation of FPGA based solution for converting signal from cameras with HD-SDI, analogue and camera link interfaces to common HDMI format. Main challenges like: frame rate equalization, image resolution adaptation and acts in case of camera connection loss are described in details. As a practical example we gave details about system with HD-SDI visible light camera, HD MWIR camera and analogue SWIR camera. In order to achieve target visibility in different day/night and meteorological conditions a multi-sensor imaging system combines signals from visible light camera, short wave infrared (SWIR) camera and medium (MWIR) or long (LWIR) wave infrared camera. Usually cameras originate from different vendor, with different interfaces, resolutions and frame rate. In order to enable further processing like image stabilization, enhancement, target tracking and image fusion, formats from all cameras should be converted to the same format.
Obesogenic diet and targeted deletion of potassium channel Kv1.3 have differing effects on voluntary exercise in mice

Voluntary exercise is frequently employed as an intervention for obesity. The voltage-gated potassium Kv1.3 is also receiving attention as a therapeutic target for obesity, in addition to potential therapeutic capabilities for neuroinflammatory diseases. To investigate combinatorial effects of these two therapies, we have compared the metabolic status and voluntary exercise behavior of both wildtype mice and a transgenic line of mice that are genetic knockouts for Kv1.3 when provided with a running wheel and maintained on diets of differing fat content and caloric density. We tracked metabolic parameters and wheel running behavior while maintaining the mice on their assigned treatment for 6 months. Wildtype mice maintained on the fatty diet gain a significant amount of bodyweight and adipose tissue and display significantly impaired glucose tolerance, though all these effects were partially reduced with provision of a running wheel. Similarly to previous studies, the Kv1.3-null mice were resistant to obesity, increased adiposity, and impaired glucose tolerance. Both wildtype and Kv1.3-null mice maintained on the fatty diet displayed increased wheel running activity compared to CF-fed mice which was caused primarily by a significant increase in amount of time spent running as opposed to an increase in running velocity. Interestingly, the patterns of running behavior differ between wildtype and Kv1.3-null mice, especially in how their resting periods are distributed through the dark phase. These studies indicate that voluntary exercise combats metabolic maladies and running behavior is modified by both consumption of an obesogenic diet and deletion of the Kv1.3 channel. NEW and NOTEWORTHY Kv1.3-null mice exhibit different running and resting patterns compared to wildtype mice Mice maintained on an obesogenic diet (32% kcal from fat) exhibit increased running distance and increased time spent running compared to mice fed normal rodent chow.
Sustainable Urban Transport Development by Applying a Fuzzy-AHP Model: A Case Study from Mersin, Turkey

Sustainable development decisions generally require citizen participation in the decision process to avoid public resistance and objections in the long term. Because of the involvement of non-experts, the uncertainty of the decision is increased, and this must be considered in the decision-making process. This paper aims to introduce a sustainable urban transport development problem in which citizens are involved to allow them to express their preferences for improving certain elements of the public bus system. To mitigate the uncertainty of the non-expert evaluations, a fuzzy-analytic hierarchy process (AHP) model has been created and applied. Since the objective of the research is to provide a suitable framework for transport development tenders, only the criteria weights have to be determined; thus, an alternative level has not been applied. The model has been tested on the urban bus transport system of a large Turkish city: Mersin. Based on the application, citizen preference weights could be associated with certain elements of the supply quality; thus, government development source allocation decisions could be supported. The fuzzy-AHP model ensures that the final development implications will meet public demand for bus system improvement in the city.
Impacts of climate and insect herbivory on productivity and physiology of trembling aspen (Populus tremuloides) in Alaskan boreal forests

Climate change is impacting forested ecosystems worldwide, particularly in the Northern Hemisphere where warming has increased at a faster rate than the rest of the globe. As climate warms, trembling aspen (Populus tremuloides) is expected to become more successful in northern boreal forests because of its current presence in drier areas of North America. However, large-scale productivity decline of aspen has recently been documented throughout the United States and Canada as a result of drought and insect outbreaks. We used tree ring measurements (basal area increment (BAI) and stable carbon isotopes (δ13C)) and remote sensing indices of vegetation productivity (NDVI) to study the impact of climate and damage by the aspen epidermal leaf miner (Phyllocnistis populiella) on aspen productivity and physiology in interior Alaska. We found that productivity decreased with greater leaf mining and was not sensitive to growing season (GS) moisture availability. Although productivity decreased during high leaf mining years, it recovered to pre-outbreak levels during years of low insect damage, suggesting a degree of resilience to P. populiella mining. Climate and leaf mining interacted to influence tree ring δ13C, with greater leaf mining resulting in decreased δ13C when GS moisture availability was low. We also found that NDVI was negatively associated with leaf mining, and positively correlated with BAI and the δ13C decrease corresponding to mining. This suggests that NDVI is capturing not only variations in productivity, but also changes in physiology associated with P. populiella. Overall, these findings indicate that the indirect effects of P. populiella mining have a larger impact on aspen productivity and physiology than climate under current conditions, and is essential to consider when assessing growth, physiology and NDVI trends in interior Alaska.
A compact dual‐band filtering antenna for wireless local area network applications

A printed dual‐band filtering antenna with decent frequency selectivity at 2.45 and 5.2 GHz for wireless local area network (WLAN) applications is developed. The filtering antenna is compact, which comprises a tapped feed line, two dual‐band stub‐loaded open‐loop resonators, and a dual‐band bended monopole. It can be easily printed on a single layer PCB substrate with low profile and low cost. The entire structure is very simple compared with the previously reported dual‐band filtering antennas that requiring multi‐layer structures. The monopole functions as not only a radiator, but also the last resonator of a dual‐band filter. The developed antenna exhibits good frequency selectivity and out‐of‐band suppression. In addition, the two operation bands can be adjusted relatively individually. The proposed antenna is optimized and fabricated. The experimental results show it has good frequency selectivity at both 2.45 and 5.2 GHz, wide bandwidth 11.8% and 7.8%, and excellent out‐of‐band suppression.
Petrochronology of oxidized granulites from southern Peru

Sapphirine–quartz granulites from the Cocachacra region of the Arequipa Massif in southern Peru record early Neoproterozoic ultrahigh‐temperature metamorphism. Phase equilibrium modelling and zircon petrochronology are used to quantify timing and pressure–temperature (P–T) conditions of metamorphism. Modelling of three magnetite‐bearing sapphirine–quartz samples indicates peak temperatures of >950°C at ~0.7 GPa and a clockwise P–T evolution. Elevated concentrations of Al in orthopyroxene are also consistent with ultrahigh‐temperature conditions. Neoblastic zircon records ages of c. 1.0–0.9 Ga that are interpreted to record protracted ultrahigh‐temperature metamorphism. Th/U ratios of zircon of up to 100 reflect U‐depleted whole‐rock compositions. Concentrations of heavy rare earth elements in zircon do not show systematic trends with U–Pb age but do correlate with variable whole‐rock compositions. Very large positive Ce anomalies in zircon from two samples probably relate to strongly oxidizing conditions during neoblastic zircon crystallization. Low concentrations of Ti‐in‐zircon (<10 ppm) are interpreted to result from reduced titania activities due to the strongly oxidized nature of the granulites and the sequestration of titanium‐rich minerals away from the reaction volume. Whole‐rock compositions and oxidation state have a strong influence on the trace element composition of metamorphic zircon, which has implications for interpreting the geological significance of ages retrieved from zircon in oxidized metamorphic rocks.
AWARD NUMBER: W81XWH-13-1-0400 TITLE: Targeting Epigenetics Therapy for Estrogen Receptor-Negative Breast Cancers PRINCIPAL INVESTIGATOR: Dewey G. McCafferty, Ph.D. CONTRACTING ORGANIZATION: Duke University

Flavin-dependent, lysine-specific protein demethylases (KDM1s) are a subfamily of amine oxidases that catalyze the selective posttranslational oxidative demethylation of methyllysine side chains within protein and peptide substrates. KDM1s participate in the widespread epigenetic regulation of both normal and disease state transcriptional programs. Their activities are central to various cellular functions, such as hematopoietic and neuronal differentiation, cancer proliferation and metastasis, and viral lytic replication and establishment of latency. Interestingly, KDM1s function as catalytic subunits within complexes with coregulatory molecules that modulate enzymatic activity of the demethylases and coordinate their access to specific substrates at distinct sites within the cell and chromatin. Although several classes of KDM1-selective small molecule inhibitors have been recently developed, these pan-active site inhibition strategies lack the ability to selectively discriminate between KDM1 activity in specific, and occasionally opposing, functional contexts within these complexes. Here we review the discovery of this class of demethylases, their structures, chemical mechanisms, and specificity. Additionally, we review inhibition of this class of enzymes as well as emerging interactions with coregulatory molecules that regulate demethylase activity in highly specific functional contexts of biological and potential therapeutic importance.

Male infertility and environmental factors

Semen quality in men is decreasing. Numerous chemicals act as endocrine-disrupting agents and their detrimental effect on fertility and spermatogenesis has been shown in rodent studies. Consequences in humans are challenging to study and effects of fetal exposure on fertility are apparent only 2 decades later. Appropriate animal models are needed to study the reproductive effects of the thousands of chemicals that humans come in contact with. The burden of proof of chemical safety must shift from the individual and health care provider to the manufacturers similar to the licensing of medical drugs.
