Title: Propagule pressure and resource availability determine plant community invasibility in a temperate forest understorey
Abstract: Few field experiments have examined the effects of both resource availability and propagule pressure on plant community invasibility. Two non-native forest species, a herb and a shrub (Hesperis matronalis and Rhamnus cathartica, respectively), were sown into 60 1-m 2 sub-plots distributed across three plots. These contained reconstructed native plant communities in a replaced surface soil layer in a North American forest interior. Resource availability and propagule pressure were manipulated as follows: understorey light level (shaded/unshaded), nutrient availability (control/fertilized), and seed pressures of the two non-native species (control/low/high). Hesperis and Rhamnus cover and the above-ground biomass of Hesperis were significantly higher in shaded sub-plots and at greater propagule pressures. Similarly, the above-ground biomass of Rhamnus was significantly increased with propagule pressure, although this was a function of density. In contrast, of species that seeded into plots from the surrounding forest during the growing season, the non-native species had significantly greater cover in unshaded sub-plots. Plants in these unshaded sub-plots were significantly taller than plants in shaded sub-plots, suggesting a greater fitness. Total and non-native species richness varied significantly among plots indicating the importance of fine-scale dispersal patterns. None of the experimental treatments influenced native species. Since the forest seed bank in our study was colonized primarily by non-native ruderal species that dominated understorey vegetation, the management of invasions by non-native species in forest understoreys will have to address factors that influence light levels and dispersal pathways.

Title: COVID-19 Disruptions Disproportionately Affect Female Academics
Abstract: The rapid spread of the COVID-19 pandemic and subsequent countermeasures, such as school closures, the shift to working from home, and social distancing are disrupting economic activity around the world. As with other major economic shocks, there are winners and losers, leading to increased inequality across certain groups. In this project, we investigate the effects of COVID-19 disruptions on the gender gap in academia. We administer a global survey to a broad range of academics across various disciplines to collect nuanced data on the respondents’ circumstances, such as a spouse’s employment, the number and ages of children, and time use. We find that female academics, particularly those who have children, report a disproportionate reduction in time dedicated to research relative to what comparable men and women without children experience. Both men and women report substantial increases in childcare and housework burdens, but women experienced significantly larger increases than men did.

Title: A High-Power Temperature-Stable Electrostatic RF MEMS Capacitive Switch Based on a Thermal Buckle-Beam Design
Abstract: This paper presents the design, fabrication and measurements of a novel vertical electrostatic RF MEMS switch which utilizes the lateral thermal buckle-beam actuator design in order to reduce the switch sensitivity to thermal stresses. The effect of biaxial and stress gradients are taken into consideration, and the buckle-beam designs show minimal sensitivity to these stresses. Several switches with 4,8, and 12 suspension beams are presented. All the switches demonstrate a low sensitivity to temperature, and the variation in the pull-in voltage is ~ -50 mV/°C from 25-125°C. The change in the up-state capacitance for the same temperature range is <; ± 3%. The switches also exhibit excellent RF and mechanical performances, and a capacitance ratio of ~ 20-23 (Cυ. = 85-115 fF, Cd = 1.7-2.6 pF) with Q > 150 at 10 GHz in the up-state position is reported. The mechanical resonant frequencies and quality factors are fο = 60-160 kHz and Qm = 2.3-4.5, respectively. The measured switching and release times are ~ 2-5 μs and ~ 5-6.5 μs, respectively. Power handling measurements show good stability with ~ 4 W of incident power at 10 GHz.

Title: Flexible capacitive pressure sensor with sensitivity and linear measuring range enhanced based on porous composite of carbon conductive paste and polydimethylsiloxane
Abstract: In recent years, the development of electronic skin and smart wearable body sensors has put forward high requirements for flexible pressure sensors with high sensitivity and large linear measuring range. However it turns out to be difficult to increase both of them simultaneously. In this paper, a flexible capacitive pressure sensor based on porous carbon conductive paste-PDMS composite is reported, the sensitivity and the linear measuring range of which were developed using multiple methods including adjusting the stiffness of the dielectric layer material, fabricating micro-structure and increasing dielectric permittivity of dielectric layer. The capacitive pressure sensor reported here has a relatively high sensitivity of 1.1 kPa-1 and a large linear measuring range of 10 kPa, making the product of the sensitivity and linear measuring range is 11, which is higher than that of the most reported capacitive pressure sensor to our best knowledge. The sensor has a detection of limit of 4 Pa, response time of 60 ms and great stability. Some potential applications of the sensor were demonstrated such as arterial pulse wave measuring and breathe measuring, which shows a promising candidate for wearable biomedical devices. In addition, a pressure sensor array based on the material was also fabricated and it could identify objects in the shape of different letters clearly, which shows a promising application in the future electronic skins.

Title: Natural Biowaste-Cocoon-Derived Granular Activated Carbon-Coated ZnO Nanorods: A Simple Route To Synthesizing a Core–Shell Structure and Its Highly Enhanced UV and Hydrogen Sensing Properties
Abstract: Granular activated carbon (GAC) materials were prepared via simple gas activation of silkworm cocoons and were coated on ZnO nanorods (ZNRs) by the facile hydrothermal method. The present combination of GAC and ZNRs shows a core-shell structure (where the GAC is coated on the surface of ZNRs) and is exposed by systematic material analysis. The as-prepared samples were then fabricated as dual-functional sensors and, most fascinatingly, the as-fabricated core-shell structure exhibits better UV and H2 sensing properties than those of as-fabricated ZNRs and GAC. Thus, the present core-shell structure-based H2 sensor exhibits fast responses of 11% (10 ppm) and 23.2% (200 ppm) with ultrafast response and recovery. However, the UV sensor offers an ultrahigh photoresponsivity of 57.9 A W-1, which is superior to that of as-grown ZNRs (0.6 A W-1). Besides this, switching photoresponse of GAC/ZNR core-shell structures exhibits a higher switching ratio (between dark and photocurrent) of 1585, with ultrafast response and recovery, than that of as-grown ZNRs (40). Because of the fast adsorption ability of GAC, it was observed that the finest distribution of GAC on ZNRs results in rapid electron transportation between the conduction bands of GAC and ZNRs while sensing H2 and UV. Furthermore, the present core-shell structure-based UV and H2 sensors also well-retained excellent sensitivity, repeatability, and long-term stability. Thus, the salient feature of this combination is that it provides a dual-functional sensor with biowaste cocoon and ZnO, which is ecological and inexpensive.

Title: A National Iranian Cochlear Implant Registry (ICIR): cochlear implanted recipient
            observational study
Abstract: BACKGROUND AND OBJECTIVE Patients who receive cochlear implants (CIs) constitutes a significant population in Iran. This population needs regular monitor on long-term outcomes, educational placement and quality of life. Currently, there is no national or regional registry on the long term outcomes of CI users in Iran. The present study aims to introduce the design and implementation of a national patient-outcomes registry on CI recipients for Iran. This Iranian CI registry (ICIR) provides an integrated framework for data collection and sharing, scientific communication and collaboration inCI research. METHODS The national ICIR is a prospective patient-outcomes registry for patients who are implanted in one of Iranian centers. The registry is based on an integrated database that utilizes a secure web-based platform to collect response data from clinicians and patient's proxy via electronic case report forms (e-CRFs) at predefined intervals. The CI candidates are evaluated with a set of standardized and non-standardized questionnaires prior to initial device activation(as baseline variables) and at three-monthly interval follow-up intervals up to 24 months and annually thereafter. RESULTS The software application of the ICIR registry is designed in a user-friendly graphical interface with different entry fields. The collected data are categorized into four subsets including personal information, clinical data, surgery data and commission results. The main parameters include audiometric performance of patient, device use, patient comorbidities, device use, quality of life and health-related utilities, across different types of CI devices from different manufacturers. CONCLUSION The ICIR database could be used by the increasingly growing network of CI centers in Iran. Clinicians, academic and industrial researchers as well as healthcare policy makers could use this database to develop more effective CI devices and better management of the recipients as well as to develop national guidelines.

Title: Diseases and Health Outcomes Registry Systems in I.R. Iran: Successful Initiative to Improve Public Health Programs, Quality of Care, and Biomedical Research
Abstract: Registration systems for diseases and other health outcomes provide important resource for biomedical research, as well as tools for public health surveillance and improvement of quality of care. The Ministry of Health and Medical Education (MOHME) of Iran launched a national program to establish registration systems for different diseases and health outcomes. Based on the national program, we organized several workshops and training programs and disseminated the concepts and knowledge of the registration systems. Following a call for proposals, we received 100 applications and after thorough evaluation and corrections by the principal investigators, we approved and granted about 80 registries for three years. Having strong steering committee, committed executive and scientific group, establishing national and international collaboration, stating clear objectives, applying feasible software, and considering stable financing were key components for a successful registry and were considered in the evaluation processes. We paid particulate attention to non-communicable diseases, which constitute an emerging public health problem. We prioritized establishment of regional population-based cancer registries (PBCRs) in 10 provinces in collaboration with the International Agency for Research on Cancer. This initiative was successful and registry programs became popular among researchers and research centers and created several national and international collaborations in different areas to answer important public health and clinical questions. In this paper, we report the details of the program and list of registries that were granted in the first round.

Title: Comparison of Airborne Hyperspectral Data and EO-1 Hyperion for Mineral Mapping
Abstract: Airborne hyperspectral data have been available to researchers since the early 1980s and their use for geologic applications is well documented. The launch of the National Aeronautics and Space Administration Earth Observing 1 Hyperion sensor in November 2000 marked the establishment of a test bed for spaceborne hyperspectral capabilities. Hyperion covers the 0.4-2.5-/spl mu/m range with 242 spectral bands at approximately 10-nm spectral resolution and 30-m spatial resolution. Analytical Imaging and Geophysics LLC and the Commonwealth Scientific and Industrial Research Organisation have been involved in efforts to evaluate, validate, and demonstrate Hyperions's utility for geologic mapping in a variety of sites in the United States and around the world. Initial results over several sites with established ground truth and years of airborne hyperspectral data show that Hyperion data from the shortwave infrared spectrometer can be used to produce useful geologic (mineralogic) information. Minerals mapped include carbonates, chlorite, epidote, kaolinite, alunite, buddingtonite, muscovite, hydrothermal silica, and zeolite. Hyperion data collected under optimum conditions (summer season, bright targets, well-exposed geology) indicate that Hyperion data meet prelaunch specifications and allow subtle distinctions such as determining the difference between calcite and dolomite and mapping solid solution differences in micas caused by substitution in octahedral molecular sites. Comparison of airborne hyperspectral data [from the Airborne Visible/Infrared Imaging Spectrometer (AVIRIS)] to the Hyperion data establishes that Hyperion provides similar basic mineralogic information, with the principal limitation being limited mapping of fine spectral detail under less-than-optimum acquisition conditions (winter season, dark targets) based on lower signal-to-noise ratios. Case histories demonstrate the analysis methodologies and level of information available from the Hyperion data. They also show the viability of Hyperion as a means of extending hyperspectral mineral mapping to areas not accessible to aircraft sensors. The analysis results demonstrate that spaceborne hyperspectral sensors can produce useful mineralogic information, but also indicate that SNR improvements are required for future spaceborne sensors to allow the same level of mapping that is currently possible from airborne sensors such as AVIRIS.

Title: Formal Linked Data Visualization Model
Abstract: Recently, the amount of semantic data available in the Web has increased dramatically. The potential of this vast amount of data is enormous but in most cases it is difficult for users to explore and use this data, especially for those without experience with Semantic Web technologies. Applying information visualization techniques to the Semantic Web helps users to easily explore large amounts of data and interact with them. In this article we devise a formal Linked Data Visualization Model (LDVM), which allows to dynamically connect data with visualizations. We report about our implementation of the LDVM comprising a library of generic visualizations that enable both users and data analysts to get an overview on, visualize and explore the Data Web and perform detailed analyzes on Linked Data.

Title: A Systematic Review of Information Literacy Programs in Higher Education: Effects of Face-to-Face, Online, and Blended Formats on Student Skills and Views
Abstract: Objective – Evidence from systematic reviews a decade ago suggested that face-to-face and online methods to provide information literacy training in universities were equally effective in terms of skills learnt, but there was a lack of robust comparative research. The objectives of this review were (1) to update these findings with the inclusion of more recent primary research; (2) to further enhance the summary of existing evidence by including studies of blended formats (with components of both online and face-to-face teaching) compared to single format education; and (3) to explore student views on the various formats employed. Methods – Authors searched seven databases along with a range of supplementary search methods to identify comparative research studies, dated January 1995 to October 2016, exploring skill outcomes for students enrolled in higher education programs. There were 33 studies included, of which 19 also contained comparative data on student views. Where feasible, meta-analyses were carried out to provide summary estimates of skills development and a thematic analysis was completed to identify student views across the different formats. Results – A large majority of studies (27 of 33; 82%) found no statistically significant difference between formats in skills outcomes for students. Of 13 studies that could be included in a meta-analysis, the standardized mean difference (SMD) between skill test results for face-to-face versus online formats was -0.01 (95% confidence interval -0.28 to 0.26). Of ten studies comparing blended to single delivery format, seven (70%) found no statistically significant difference between formats, and the remaining studies had mixed outcomes. From the limited evidence available across all studies, there is a potential dichotomy between outcomes measured via skill test and assignment (course work) which is worthy of further investigation. The thematic analysis of student views found no preference in relation to format on a range of measures in 14 of 19 studies (74%). The remainder identified that students perceived advantages and disadvantages for each format but had no overall preference. Conclusions – There is compelling evidence that information literacy training is effective and well received across a range of delivery formats. Further research looking at blended versus single format methods, and the time implications for each, as well as comparing assignment to skill test outcomes would be valuable. Future studies should adopt a methodologically robust design (such as the randomized controlled trial) with a large student population and validated outcome measures.

Title: Expanding horizons in historical linguistics with the 400-million word Corpus of Historical American English
Abstract: The Corpus of Historical American English (COHA) contains 400 million words in more than 100,000 texts which date from the 1810s to the 2000s. The corpus contains texts from fiction, popular magazines, newspapers and non-fiction books, and is balanced by genre from decade to decade. It has been carefully lemmatised and tagged for part-of-speech, and uses the same architecture as the Corpus of Contemporary American English (COCA), BYU-BNC, the TIME Corpus and other corpora. COHA allows for a wide range of research on changes in lexis, morphology, syntax, semantics, and American culture and society (as viewed through language change), in ways that are probably not possible with any text archive (e.g., Google Books) or any other corpus of historical American English.

Title: Softcite dataset: A dataset of software mentions in biomedical and economic research publications
Abstract: Software contributions to academic research are relatively invisible, especially to the formalized scholarly reputation system based on bibliometrics. In this article, we introduce a gold‐standard dataset of software mentions from the manual annotation of 4,971 academic PDFs in biomedicine and economics. The dataset is intended to be used for automatic extraction of software mentions from PDF format research publications by supervised learning at scale. We provide a description of the dataset and an extended discussion of its creation process, including improved text conversion of academic PDFs. Finally, we reflect on our challenges and lessons learned during the dataset creation, in hope of encouraging more discussion about creating datasets for machine learning use.
