Transconductance fluctuations as a probe for interaction induced quantum Hall states in graphene

Transport measurements normally provide a macroscopic, averaged view of the sample, so that disorder prevents the observation of fragile interaction induced states. Here, we demonstrate that transconductance fluctuations in a graphene field effect transistor reflect charge localization phenomena on the nanometer scale due to the formation of a dot network which forms near incompressible quantum states. These fluctuations give access to fragile broken-symmetry and fractional quantum Hall states even though these states remain hidden in conventional magnetotransport quantities.Comment: 6 pages, 3 figure

The Internet and health information: differences in pet owners based on age, gender, and education

Objective: The research assessed the attitudes and behaviors of pet owners pertaining to online search behavior for pet health information. Methods: A survey was conducted with a random sample of pet owners drawn from two US metropolitan areas and surrounding cities. Participating clinics were chosen randomly, and each participating clinic was asked to distribute 100 surveys to their clients until all surveys were disbursed. Results: Although some perceptions and behaviors surrounding the use of the Internet for pet health information differ based on gender, age, or education level of pet owners, there are many aspects in which there are no differences based on these demographics. Conclusions: Results of the study suggest that closer examination of the common perception that gender, age, or education level has an effect on Internet behavior as it relates to veterinary medicine is required. Recommendations are made pertaining to the growing presence of the Internet and its impact on veterinary medicine. doi: 10.3163/1536-5050.100.3.01

Health Services, Maternal Intrinsic and Socio-Cultural Factors and Perinatal Mortality

This study question was how significant the determination of health services, maternal intrinsic risk factors and socio-cultural factors on perinatal mortality. Its objective was to construct a model of perinatal mortality pattern by case-control design. The case population was all mothers with perinatal mortality. The sample-size was 35 by simple random sampling with case-control ratio of 1:1 (35:35). The data analysis applied Bivariate using Chi Square Test and Multivariate using Logistic Regression Test. The Bivariate Analysis Results found the risk-variables on Perinatal Mortality were Birth Attendant (OR=2.1; 1.63-2.7; 95%CI), Health Financing (OR=7.1; 1.82-27.8; 95% CI), Maternal Disease History (OR=8; 2.05-31.16; 95%CI), Perinatal History (OR=6.47; 2.26-18.55; 95%CI) and Custom (OR=2.17; 1.67-2.82; 95%CI). Multivariat Analysis found three consistent risk variables on Perinatal Mortality i.e.: Health Financing (p=0.016; OR=6.8; 95% CI), Maternal Disease History (p=0.006; OR=8.41; 95%CI) and Perinatal History (p=0.021; OR=4.3; 95%CI). It concluded that the most significant determinant on Perinatal Mortality was Maternal Disease History

The Role of Veterinary Medical Librarians in Teaching Information Literacy

This qualitative study seeks to determine the nature of the instruction librarians provide to veterinary medical students at all 28 United States veterinary colleges. A secondary goal of the study was to determine in what ways and to what extent librarians participated in other instructional activities at their colleges. Over half of the librarians formally taught in one or more courses, predominantly in the first two years of the veterinary curriculum. One presentation per course was most common. Over half of the librarians interviewed stated that evidence-based veterinary medicine was taught at their colleges, and about half of these librarians collaborated with veterinary faculty in this instruction. Many librarians participated in orientation for first-year veterinary students. The librarians also taught instructional sessions for residents, interns, faculty, graduate students, and practicing veterinarians. This study found that librarians teach information literacy skills both formally and informally, but, in general, instruction by librarians was not well integrated into the curriculum. This study advances several recommendations to help veterinary students develop information literacy skills. These include: encourage veterinary faculty and administrators to collaborate more closely with librarians, incorporate a broader array of information literacy skills into assignments, and add a literature evaluation course to the curriculum

Morphological Study of Granular-Granular Impact Craters through Time-of-Flight Cameras: from Concept to Automation in Python

Laboratory made granular-granular impact craters have been used as model analogues of planetary impact craters. These kind of craters have been observed and studied using profilometry techniques that allow to retrieve important morphologic features from the impacted surface. In this work, we propose to use a Time-of-Flight camera (Microsoft Kinect One) for the acquisition of depth data. We show comparisons between the typically used technique and the analysis derived from the Time-of-Flight data. We also release craterslab, a Python library developed to automate most of the tasks from the process of studying impact craters produced by granular projectiles hitting on the surface of granular targets. The library is able to acquire, identify, and measure morphological features of impacted surfaces through the reconstruction of 3D topographic maps. Our results show that using a Time-of-Flight camera and automating the data processing with a software library for the systematic study of impact craters can produce very accurate results while reducing the time spent on different stages of the process

From Campus to Community: Making the Case for Open Access by Bringing Nonprofits to Academic Libraries

Summary: Describes how librarians developed a workshop for nonprofit organizations (NPOs) to help NPOs access peer-reviewed publications behind paywalls, develop skills in searching (information retrieval), and improve awareness of how academic libraries can support community organizations. NPOs who participated gave feedback in a number of ways, from written surveys to short recorded video interviews. With permission, their feedback was used to develop promotional and informational materials intended for the campus about the value of open access to those working in the local community

Enhanced Tunnelling in a Hybrid of Single-Walled Carbon Nanotubes and Graphene

Transparent and conductive films (TCFs) are of great technological importance. The high transmittance, electrical conductivity and mechanical strength make single-walled carbon nanotubes (SWCNTs) a good candidate for their raw material. Despite the ballistic transport in individual SWCNTs, however, the electrical conductivity of their networks is limited by low efficiency of charge tunneling between the tube elements. Here, we demonstrate that the nanotube network sheet resistance at high optical transmittance is decreased by more than 50% when fabricated on graphene and thus provides a comparable improvement as widely adopted gold chloride ($\mathrm{AuCl_3}$) doping. However, while Raman spectroscopy reveals substantial changes in spectral features of doped nanotubes, no similar effect is observed in presence of graphene. Instead, temperature dependent transport measurements indicate that graphene substrate reduces the tunneling barrier heights while its parallel conductivity contribution is almost negligible. Finally, we show that combining the graphene substrate and $\mathrm{AuCl_3}$ doping, the SWCNT thin films can exhibit sheet resistance as low as 36 $\Omega$/sq. at 90% transmittance.Comment: 21 pages, 6 figure
