Techniques and architecture are disclosed for preserving optical surfaces (e.g., windows, coatings, etc.) in a flowing gas amplifier laser system, such as a diode-pumped alkali laser (DPAL) system. In some instances, the disclosed techniques/architecture can be used, for example, to protect optical surfaces in a DPAL system from: (1) chemical attack by pump-bleached alkali vapor atoms and/or ions; and/or (2) fouling by adherence thereto of reaction products/soot produced in the DPAL. Also, in some instances, the disclosed techniques/architecture can be used to substantially match the geometry of the pumping volume with that of the lasing volume, thereby minimizing or otherwise reducing the effects of amplified spontaneous emission (ASE) on DPAL output power. Furthermore, in some cases, the disclosed techniques/architecture can be used to provide a DPAL system capable of producing a beam output power in the range of about 20 kW to 10 MW, or greater.

An auxetic structure consistent with the present disclosure may include a core cell, capable of rotation, including a plurality of first rib sections, and a plurality of second rib sections. The first rib sections may be transverse to a longitudinal axis of the auxetic structure and at least one of the first rib sections may extend from the core cell. The second rib sections may be transverse to a transverse axis of the auxetic structure and at least one of the second rib sections may extend from the core cell.

A sensor-equipped laryngoscope may be used in a system and method for quantifying intubation performance. The level of experience of health care professionals (HCPs) plays a role in the application of force and torque applied to the laryngoscope during endotracheal intubation on an airway simulator, such as a manikin or animal model (e.g., a ferret). A sensor-equipped laryngoscope may provide data that differentiates the mechanics applied by subject matter experts (SMEs) (e.g., neonatologists) from those by novices or trainees during intubation, particularly on infant or neonatal airway simulators. A laryngoscope may be equipped with one or more sensors (e.g., force/torque sensors, accelerometers, and gyroscopes) to record force, torque, and/or three-dimensional motion during endotracheal intubation. The sensor-equipped laryngoscope may then be used to record intubation mechanics (e.g., during an infant airway simulated intubation) for both SMEs and trainees.

Whether salient objects automatically capture attention has long been the subject of considerable controversy. A possible resolution, investigated in this functional magnetic resonance imaging (fMRI) study, is that observers vacillate between periods when attention capture is robust and when it is minimal. Human observers searched static displays for a target circle among nontarget squares; an irrelevant color singleton distractor appeared on 50% of trials. Behavioral results showed a distraction effect in which response times to distractor-present trials were slower than for distractor-absent trials. fMRI results confirmed that this distraction effect not only fluctuated within experimental sessions, but the momentary degree of distraction could be predicted in advance by pretrial activity in middle frontal gyrus. A second experiment ruled out an alternative account by which participants achieved resistance to capture by trading off search efficiency. Together, these data reveal that observers frequently exert the capacity to resist attentional distraction, although they do not to sustain this capacity for long periods of time.

How plants interact with sunlight is central to the existence of life and provides a window to the functioning of ecosystems. Although the basic properties of leaf spectra have been known for decades, interpreting canopy-level spectra is more challenging because leaf-level effects are complicated by a host of stem- and canopy-level traits. Progress has been made through empirical analyses and models, although both methods have been hampered by a series of persistent challenges. Here, I review current understanding of plant spectral properties with respect to sources of uncertainty at leaf to canopy scales. I also discuss the role of evolutionary convergence in plant functioning and the difficulty of identifying individual properties among a suite of interrelated traits. A pattern that emerges suggests a synergy among the scattering effects of leaf-, stem- and canopy-level traits that becomes most apparent in the near-infrared (NIR) region. This explains the widespread and well-known importance of the NIR region in vegetation remote sensing, but presents an interesting paradox that has yet to be fully explored: that we can often gain more insight about the functioning of plants by examining wavelengths that are not used in photosynthesis than by examining those that are. © 2010 The Author.

Solar Particle Events (SPEs) represent a major hazard for extravehicular maneuvers by astronauts in Earth orbit, and for eventual manned interplanetary space travel. They can also harm aircraft avionics, communication and navigation. We propose to develop a system to aid forecasters in the prediction of such events, and in the identification/lengthening of "all clear" time periods when there is a low probability of such events occurring. The system leverages three recently developed technologies: physics-based models of the solar corona and inner heliosphere, robust CME modeling techniques, and empirical/physics-based assessments of energetic particle fluxes using the Earth-Moon-Mars Radiation Environment Module (EMMREM, University of New Hampshire). When completed, the proposed SPE Threat Assessment Tool, or STAT, will represent a significant step forward in our ability to assess the possible impact of SPE events.

Many surface waters are yellow or brown in color due to the presence of organic molecules which come from many natural sources such as leaves, soils, and wetlands. These molecules affect a wide range of characteristics within streams such as the ability of light to penetrate the water and the acidity of the water. The organic molecules also can provide streams with energy and essential nutrients such as nitrogen and phosphorus. One particularly important form of these organic molecules is dissolved organic nitrogen, which is found globally in forests, arctic tundra, estuaries and streams. However, very little is known about when and where dissolved organic nitrogen serves as a source of energy, a source of nitrogen, or both to biological communities. This project will examine the role of dissolved organic nitrogen in streams across five distinct forested regions spanning a diverse set of environments in an effort to shed light on the role of dissolved organic nitrogen. This research is relevant to water resources management because dissolved organic nitrogen is a source of excessive nutrient loading causing toxic algal blooms in estuaries, and when it is found in drinking water supplies it can produce, during water treatment, disinfection by-products that can harm human health. This research will also integrate under-represented groups into the laboratory work and field work needed for the project and provide training opportunities for a graduate student and a post-doctoral scientist.

Differentiating among the competing roles for dissolved organic nitrogen (DON) is difficult, as direct manipulation of the DON pool in aquatic ecosystems is most easily accomplished by addition of specific compounds such as amino acids, which are commercially available but are not particularly representative of the DON found in streams and rivers under ambient conditions. Based on initial experimental results, the researchers will conduct a series of novel field manipulations in streams across New England, Puerto Rico, Spain, Czech Republic, and Siberia to better understand the extent to which DON serves as an energy source or nitrogen source in streams globally. Initial experimental observations in New England show that the DON can serve as both a nitrogen source and an energy source, but its role appears to vary over space and time. Here the researchers will perform additional experiments where nitrate pulses are added to streams across a global network to assess how frequently, and under what conditions, DON serves predominantly as a nitrogen source, versus an energy (carbon) source. This set of experiments will provide some of the first experimental evidence to assess the importance of these two competing drivers in regulating the levels of ambient DON in natural waters.

Coral reefs, the tropical rain forests of the marine environment, are under significant threat from a variety of stressors such as pollution, overfishing, coastal development and climate change. There is increasing interest by the coral reef research community in the ecology and evolution of other groups of organisms besides corals on coral reefs with sponges being of particular interest. Sponges are a very old group of organisms essential to reef health because of their roles in nutrient cycling, providing food and homes for many other reef organisms, and their ability to synthesize diverse chemical compounds of ecological importance on the reef, and of interest to the biomedical community. Many of these important functions would not be possible without the symbiotic microbes (e.g., bacteria) that live within sponges. In this project, the investigators will examine relationships between the sponge host and its microbiome in the ecological roles described above. Like the human microbiome, understanding the sponge micobiome may be the key to understanding their ecology and biodiversity. The investigators will use a combination of classical ecological approaches combined with sophisticated biochemical and molecular analyses to unravel the role of the symbionts in the ecology and evolution of sponges. Both the University of New Hampshire and the University of Mississippi will provide training opportunities for undergraduate and graduate students as well as veterans and post-doctoral researchers, especially from underrepresented groups. Additionally, the investigators will develop unique outreach programs for public education on the importance of coral reef ecosystems.

The goal of this study is to examine the relationships between marine sponges and their microbiomes, and reveal the phylogenetic, genetic, and functional biodiversity of coral reef sponges across the Caribbean basin. This research will provide a better understanding of sponges as a major functional component of the biodiversity of coral reef communities. This transformative project will examine important paradigms relative to sponge communities worldwide that will provide unique insights into the integrative biodiversity of sponges on coral reefs and enhance our understanding of the ecology and evolution of this extensive, yet understudied, group of marine organisms. This is essential because sponges continue to emerge as the dominant taxon on many coral reefs, particularly following regional declines in coral cover over the last three decades, and their ecological importance to shallow coral reef communities is unequivocal. In addition, many marine sponges host a diverse assemblage of symbiotic microorganisms that play critical functional roles in nutrient cycling within sponges themselves and in the coral reef communities where they reside, and many sponges can potentially transfer photoautotrophically derived energy to higher trophic levels. As shallow coral reefs continue to decline, the phylogenetic, genetic, and functional diversity of coral reefs will increasingly be found in taxa other than scleractinian corals, such as soft corals and sponges. The investigators predict that co-evolution of the sponge host and microbiome leads to emergent functional properties that result in niche diversification and speciation of sponges. To assess this, they will quantify trophic modes (e.g., DOM and POC uptake, photo-autotrophy) of sponges in the Caribbean, as well as the production of chemical defenses. These character states will be analyzed in the context of the phylogenetic composition of the sponge hosts and their microbiomes, and the functional activities of the host and symbionts at the genetic level (i.e., transcriptomics and metatranscriptomics). These data will provide unique insights into the co-evolution of sponges and their microbiomes, and how these symbioses influence the functional attributes of sponges within coral reef communities.

Biological diversity is important to human well-being and to the maintenance of a healthy environment. Without an array of species inhabiting a range of environments, the cycles of water, nutrients and biomass on which life depends would be severely compromised. Despite this, understanding exactly how diversity influences specific environmental processes is challenging. Although there are theories describing the influence of plant species diversity on environmental processes, they?ve primarily been tested in grasslands and other systems dominated by small plants, where diversity can be manipulated through planting and weeding. Forests present a challenge because the size and lifespans of trees make it difficult to conduct manipulative diversity experiments and because natural diversity gradients also vary in climate, making results difficult to interpret. Overcoming this hurdle is critical given the importance of forests to many environmental processes and the degree to which forest diversity is declining. This award will examine whether theories of biological diversity and environmental processes that have been largely tested in small-statured ecosystems also apply to macro-scale processes over North American forests. By integrating data on carbon, water, and energy exchanges between forests and the atmosphere, remote sensing of forest diversity, and field measurements, will enable the development of forest diversity for the US and the relationship to land-atmosphere exchange of carbon and water. It will quantify the important role of forests in the Earth system and the degree to which forest diversity is declining. The award will involve undergraduate and graduate students in all phases of the project, and through additional activities that bring new methods of remote sensing to private citizens, teachers and students at multiple levels. This will be accomplished through workshops and through development of focused activities that can be adopted by teachers and used in the classroom. The undergraduates working on the project will participate in the University of New Hampshire?s Undergraduate Research Conference (URC), one of the largest undergraduate research events in the country.

Understanding how diversity influences specific ecosystem and earth system functions within individual biomes is extremely difficult and is considered one of the grand challenges in ecology. Meeting this challenge is important given the number of species worldwide that have already gone extinct or have been threatened by habitat loss, pests and pathogens, harvesting, competition from non-native species, pollution, and climate change. This award will examine the effects of tree diversity in forests across the U.S. on the uptake of CO2, the transfer of water from soils to the atmosphere, and on the stability of these processes in response to climate variability. The award will test the following specific hypotheses:
(A) Biological diversity in North American forests has a positive effect on primary production and a negative effect on evapotranspiration, leading to increased water use efficiency. (B) Forests with high levels of diversity are less susceptible to extreme events and exhibit less temporal variability in carbon and water fluxes in response to climate fluctuations than low-diversity forests. These hypotheses will be addressed by bringing together several unique sources of data that have not previously been used to address this question. First, the research sites to be used are equipped with instrumented towers that make detailed measurements of CO2 and water vapor above the forest canopy, as well as a range of climate and ecological variables. Second, advanced remote sensing instruments will be used to measure tree canopy diversity in ways that field surveys alone cannot. These data will come from unmanned aerial systems as well as instruments that are part of the National Ecological Observatory. Through the unique nature of these data sets and advanced methods of data analysis, results will be used to quantify the specific signature of diversity on important processes at a broad geographic scale.

Estuaries are bodies of water formed where rivers meet the ocean, and are important ecosystems that provide protected environments and abundant food for fish and shellfish to reproduce. Many estuary systems are under pressure by changing atmospheric and oceanic conditions, as well as impacts on the rivers that empty into them. Scientists from the University of New Hampshire and the University of South Florida propose that the total alkalinity of some coastal systems, influenced by river runoff, may contain a large fraction of organic acids that have been previously ignored and may play a role in the acid-base chemistry of the estuary. This project would focus on understanding the organic and inorganic acid-base chemistry in estuaries. The project will support a PhD student and several undergraduate students, as well as high school interns from minority communities, broadening participation in the ocean sciences. Also, the monitoring and outreach capacity of a regional wild fishery conservation group will be enhanced, allowing the public to be more fully informed on the effect of ongoing estuarine changes on fisheries.

This project will be a comparison study of two estuary-plume systems to examine the exact buffering impact of organic alkalinity on the acid-base properties of coastal systems. The Pleasant (Maine) and St. John (Canada) estuaries represent extremes of river acid-base systems, where the Pleasant is comprised mostly of organic alkalinity and the St. John has a small organic alkalinity fraction. It is hypothesized by these scientists that some coastal regions may experience organic alkalinity as the dominant alkalinity factor in the total alkalinity distribution. This would mean that organic alkalinity would be the dominant factor affecting system pH, pCO2 (partial pressure of carbon dioxide), and the saturation index of aragonite. By doing this river endmember study into organic alkalinity of these two systems, these scientists will provide the tools for the entire oceanographic community to assess the buffering capability of organic alkalinity in other coastal systems and how the systems are likely to respond to acidification.
