Inhaled nitric oxide as an adjunct to neonatal resuscitation in premature infants: a pilot, double blind, randomized controlled trial.
BackgroundNitric oxide (NO) plays an important role in normal postnatal transition. Our aims were to determine whether adding inhaled NO (iNO) decreases supplemental oxygen exposure in preterm infants requiring positive pressure ventilation (PPV) during resuscitation and to study iNO effects on heart rate (HR), oxygen saturation (SpO2), and need for intubation during the first 20âmin of life.MethodsThis was a pilot, double-blind, randomized, placebo-controlled trial. Infants 25 0/7-31 6/7 weeks' gestational age requiring PPV with supplemental oxygen during resuscitation were enrolled. PPV was initiated with either oxygen (FiO2-0.30)â+âiNO at 20âppm (iNO group) or oxygen (FiO2-0.30)â+ânitrogen (placebo group). Oxygen was titrated targeting defined SpO2 per current guidelines. After 10âmin, iNO/nitrogen was weaned stepwise per protocol and terminated at 17âmin.ResultsTwenty-eight infants were studied (14 per group). The mean gestational age in both groups was similar. Cumulative FiO2 and rate of exposure to high FiO2 (>0.60) were significantly lower in the iNO group. There were no differences in HR, SpO2, and need for intubation.ConclusionsAdministration of iNO as an adjunct during neonatal resuscitation is feasible without side effects. It diminishes exposure to high levels of supplemental oxygen
A Test of Concepts Inherent in Experience Based Setting Management for Outdoor Recreation Areas
This study examines assumptions of the concepts which form the basis for experience based setting management of outdoor recreation areas. To test the assumptions a sample of wilderness users was surveyed and divided into experience groups based on differences in the specific experiences they desire. These experience groups were then tested for differences in their activity and setting preferences. The study was conducted at the Bridget Wilderness, the Fitzpatrick Wilderness, and the Popo Agie Primitive Area in Wyoming during 1978-79. Data were collected by questionnaire, and responses were examined by object cluster analysis to group users on the basis of the types of experiences important to them. Results offer support for the concepts tested; three groups with different preferences for experiences were identified and were found to differ on the activities, setting, and management actions they prefer. Directions for future research are given and recommendations concerning the usefulness of experience based information to recreation planning are discussed
Nano-Resolution Visual Identifiers Enable Secure Monitoring in Next-Generation Cyber-Physical Systems
Today's supply chains heavily rely on cyber-physical systems such as
intelligent transportation, online shopping, and E-commerce. It is advantageous
to track goods in real-time by web-based registration and authentication of
products after any substantial change or relocation. Despite recent advantages
in technology-based tracking systems, most supply chains still rely on plainly
printed tags such as barcodes and Quick Response (QR) codes for tracking
purposes. Although affordable and efficient, these tags convey no security
against counterfeit and cloning attacks, raising privacy concerns. It is a
critical matter since a few security breaches in merchandise databases in
recent years has caused crucial social and economic impacts such as identity
loss, social panic, and loss of trust in the community. This paper considers an
end-to-end system using dendrites as nano-resolution visual identifiers to
secure supply chains. Dendrites are formed by generating fractal metallic
patterns on transparent substrates through an electrochemical process, which
can be used as secure identifiers due to their natural randomness, high
entropy, and unclonable features. The proposed framework compromises the
back-end program for identification and authentication, a web-based application
for mobile devices, and a cloud database. We review architectural design,
dendrite operational phases (personalization, registration, inspection), a
lightweight identification method based on 2D graph-matching, and a deep 3D
image authentication method based on Digital Holography (DH). A two-step search
is proposed to make the system scalable by limiting the search space to samples
with high similarity scores in a lower-dimensional space. We conclude by
presenting our solution to make dendrites secure against adversarial attacks
Direct and Inverse Results on Bounded Domains for Meshless Methods via Localized Bases on Manifolds
This article develops direct and inverse estimates for certain finite
dimensional spaces arising in kernel approximation. Both the direct and inverse
estimates are based on approximation spaces spanned by local Lagrange functions
which are spatially highly localized. The construction of such functions is
computationally efficient and generalizes the construction given by the authors
for restricted surface splines on . The kernels for which the
theory applies includes the Sobolev-Mat\'ern kernels for closed, compact,
connected, Riemannian manifolds.Comment: 29 pages. To appear in Festschrift for the 80th Birthday of Ian Sloa
Determining puma habitat suitability in the Eastern USA
Pumas (Puma concolor) were eliminated from most of the eastern USA a century ago. In the past couple of decades, their recovery in the West has increased puma dispersal into the Midwest, with some individuals even traveling to the East Coast. We combined published expert opinion data and a habitat suitability index in an analysis that identified 17 areas in the Upper Midwest, Ozarks, Appalachia, and New England that could potentially host puma populations in the future. Thirteen of these were larger than 10,000 km2 and so likely to ensure a puma populationâs long-term genetic health. Further, we quantified patch size, human density, livestock density, percent public land, and a sociocultural index reflecting wildlife values for comparing patches, as well as present a summary of current legislation relevant to puma management in the East. Our work may be useful in identifying suitable areas to restore pumas based not only on the quality of their biophysical habitat, but also on social values conducive to puma-human coexistence

State fish and wildlife agency culture: Access points to leverage major change
Amid a time of unprecedented social-ecological change, professionals within and outside of the US wildlife conservation community have called for transformation of existing processes and structures to ensure that the benefits of wildlife conservation can be realized well into the future. Current momentum behind an initiative to help increase conservation relevancy among population segments that have historically been underserved by the conservation community is underway. Sustainable institutional change will not be realized, however, without attending to internal cultural change within the conservation community itself. Although elements of an ideal institution have been suggested, specific interventions related to institutional culture need deeper exploration. State fish and wildlife agencies—a primary organizational actor within the conservation community—play a central role in institutional transformation. Using a systems framework, this essay describes key leverage points for cultural change for which interventions could result in sustainable culture shifts. Five possible interventions are introduced to stimulate conversation among conservation practitioners seeking to initiate transformational change within their specific cultural contexts.

Integrating social science into conservation planning
A growing body of literature has highlighted the value of social science for conservation, yet the diverse approaches of the social sciences are still inconsistently incorporated in conservation initiatives. Building greater capacity for social science integration in conservation requires frameworks and case studies that provide concrete guidance and specific examples. To address this need, we have developed a framework aimed at expanding the role for social science in formal conservation planning processes. Our framework illustrates multiple ways in which social science research can contribute to four stages of such processes: 1) defining the problem and project team; 2) defining goals; 3) identifying impact pathways and designing interventions; and 4) developing and evaluating indicators of success (or failure). We then present a timely case study of wolf reintroduction in Colorado, U.S.A., to demonstrate the opportunities, challenges, and complexities of applying our framework in practice
