Toward an Evidence-Based System for Innovation Support for Implementing Innovations with Quality: Tools, Training, Technical Assistance, and Quality Assurance/Quality Improvement

An individual or organization that sets out to implement an innovation (e.g., a new technology, program, or policy) generally requires support. In the Interactive Systems Framework for Dissemination and Implementation, a Support System should work with Delivery Systems (national, state and/or local entities such as health and human service organizations, community-based organizations, schools) to enhance their capacity for quality implementation of innovations. The literature on the Support ystem has been under-researched and under-developed. This article begins to conceptualize theory, research, and action for an evidence-based system for innovation support (EBSIS). EBSIS describes key priorities for strengthening the science and practice of support. The major goal of EBSIS is to enhance the research and practice of support in order to build capacity in the Delivery System for implementing innovations with quality, and thereby, help the Delivery System achieve outcomes. EBSIS is guided by a logic model that includes four key support components: tools, training, technical assistance, and quality assurance/quality improvement. EBSIS uses the Getting To Outcomes approach to accountability to aid the identification and synthesis of concepts, tools, and evidence for support. We conclude with some discussion of the current status of EBSIS and possible next steps, including the development of collaborative researcher-practitioner-funder-consumer partnerships to accelerate accumulation of knowledge on the Support System.
Debris characterization techniques via unresolved long-wave infrared imaging from a space-based platform

Every space launch increases the overall amount of space debris, especially when circumstances result in the orbital objects being stranded in orbit with no deorbiting capabilities. Studies contributing to the understanding of space debris aid spacecraft operators in mitigating risk associated with Earth-orbiting debris objects. Accurately characterizing the debris threat to a spacecraft is of vital importance in maximizing the lifespan and mission capabilities of the spacecraft. This investigation aims to develop long-wave infrared radiometric-based techniques for detection and characterization of typical debris objects via signal analysis of unresolved imagery. Tumble rate, absorptivity-to-emissivity ratio, and cross-sectional area are analyzed and estimates made regarding their values. Fusion of astrometric and radiometric data allows for a more accurate, and less ambiguous, hypothesis to be reached concerning the cross-sectional area of debris objects.

The Synthesis of 8-β-[(Methylsulfinyl-[18O])-methyl]-6-propylergoline

The synthesis of 18O-labeled 8-β-[(methylsulfinyl)-methyl]-6-propyl-ergoline (pergolide-[18O]-sulfoxide) of undetermined stereochemistry by the reaction of 8-β-(methylthiomethyl)-6-propyl-ergoline (pergolide) with bis-(4-methoxyphenyl)-selen-[18O]-oxide in acetic acid is described. Although the yields were low and the incorporation of 18O was not high, this procedure represents a convenient method for the preparation of 18O-labeled sulfoxides of pergolide and other sulfides present in compounds for which the usual methods are inappropriate.
Comparative effects of two physical conditioning programs on cardiovascular fitness in man.

Abstract College men (N = 25) were selected and placed into three matched groups on the basis of maximum oxygen consumption. One group participated in a modified army conditioning program of calisthenics and marching (N = 8), while the second group participated in a program of interval training involving running (N = 9). The third group (control) participated in recreational activities (N = 8). The groups met 5 days per week for 7 weeks. Pre- and post-conditioning maximum oxygen consumption and Harvard Step Test indexes were recorded to evaluate differences. The results showed that the interval-trained group improved significantly on the two fitness tests. The army trained group showed no significant improvement in maximum oxygen consumption but did have significant improvement for the Harvard Step Test. The control group did not significantly improve.
Euglena Ferredoxin Nadp Reductase, LHCP Apoprotein, and Their Photocontrol During Chloroplast Development

Both the ferredoxin-NADP reductase (FNR) and the 26.5 kD apoprotein of the light-harvesting chlorophyll-protein complex (26.5 kD apo-LHCP) have been purified to homogeneity from Euglena (1–3). The Euglena FNR, extracted and purified without the use of detergents, is unusual in containing two polypeptides of 36 and 15 kD instead of only one 36–38 kD polypeptide (1). In this report we describe the purification, properties and cellular localization of Euglena FNR and discuss the photo control of formation of this activity in relation to that of the 26.5 kD apo-LHCP and the various chlorophyll-protein complexes in wild-type cells and mutants blocked in antenna formation.
( d , He 3 ) Reaction on Ca 40 and the Titanium Isotopes

The ($d$, ${\mathrm{He}}^{3}$) reaction on ${\mathrm{Ca}}^{40}$ and isotopically enriched targets of ${\mathrm{Ti}}^{46}$, ${\mathrm{Ti}}^{47}$, ${\mathrm{Ti}}^{48}$, ${\mathrm{Ti}}^{49}$, and ${\mathrm{Ti}}^{50}$ has been investigated. Absolute differential cross sections for a number of transitions were obtained over an angular range from 11 to 33\ifmmode^\circ\else\textdegree\fi{}. The angular distributions are compared with distorted-wave calculations which use the optical-model-potential parameters derived from the elastic scattering of 21-MeV deuterons on the same target materials. The data for the elastic scattering are given together with the optical-model fits. The ${\mathrm{Ca}}^{40}(d, {\mathrm{He}}^{3}){\mathrm{K}}^{39}$ reaction was used to obtain the normalization coefficients necessary to extract spectroscopic factors from the comparison of the measured and calculated differential cross sections. The results show that the excitation energies of the ${d}_{\frac{3}{2}}$ and ${s}_{\frac{1}{2}}$ proton-hole states are surprisingly low and increase with the number of ${f}_{\frac{7}{2}}$ neutrons in the nucleus. In the case of ${\mathrm{Sc}}^{45}$, the ${d}_{\frac{3}{2}}$ hole state which contains the full ${d}_{\frac{3}{2}}$ strength is found at an excitation energy of less than 50 keV. The excitation energy of the ${d}_{\frac{3}{2}}$ hole state increases to 800 keV for ${\mathrm{Sc}}^{47}$ and to about 2.4 MeV in ${\mathrm{Sc}}^{49}$. The excitation energy of the ${s}_{\frac{1}{2}}$ hole state increases from 0.92 MeV in ${\mathrm{Sc}}^{45}$ to 2.1 MeV in ${\mathrm{Sc}}^{48}$.
A Real-Time Brainwave Based Neuro-Feedback System for Cognitive Enhancement

Brain Computer Interface (BCI) provides a pathway to connect the brain to external devices. Neuro-rehabilitation provides advanced means to assist people with movement disorders such as post-stroke patients and those with lost limbs. While much progress has been made in neuro-rehabilitation as assistive devices, few studies had examined mental rehabilitation assisted by BCI such as memory training using neuroenhancement. It should be noted that many patients with physical disabilities also suffer cognitive difficulties. On the other hand, cognitive decline can also be the result of normal aging without brain injury nor diseases. Here, we propose a novel real-time brainwave BCI platform for enhancing human cognitive by designing and employing a personalized neuro-feedback robot. Short-term memory and attention are among the most important cognitive abilities which manifest in many mental diseases. A social robot is integrated into the BCI system to provide feedback based on individual’s brainwaves and memory performance. As a simple scenario of memory task, real-time EEG signals will be monitored during a visual object memory task. Our novel neuro-feedback system has great potential as a neuro-enhancing device for cognitive rehabilitation.Copyright © 2015 by ASME
Desert in liberal justice: beyond institutional guarantees

I argue that a theory of distributive justice is sensitive to desert if and only if it (1) does not require an institutional scheme that prevents individuals from treating one another as they deserve, and (2) requires a desert ethos. A desert ethos is a set of principles that, though not embodied in a society’s basic coercive structure, nevertheless governs interpersonal relations between citizens. These two necessary conditions are jointly sufficient for ‘giving desert its due’ in a theory of justice. I therefore reject the received view that a desert-sensitive theory must endeavor to guarantee distributions patterned according to desert.

Synthesis, characterization, and electrochemical studies of β,β'-fused metallocenoporphyrins

β,β‘-Fused monoruthenocenylporphyrins, Cp*Ru(III)[1,2-[M(II)-5,10,15,20-tetrakis(3,5-di-tert-butylphenyl)-porphyrinato]-3-methyl-cyclopentadienide] (M = Ni (20), Cu (21), Zn (22)), and bisferrocenoporphyrins, Fe(II) bis[1,2-[M(II)-5,10,15,20-tetraphenylporphyrinato]-3-methyl-cyclopentadienide] (M = Ni (24), Cu (25), Zn (26)), were synthesized and characterized. A novel synthetic approach to β,β‘-fused porphyrins through Pd(0)-catalyzed [3 + 2] cycloaddition was implemented in this work. UV−vis spectra of these compounds show largely broadened and red-shifted bands (relative to their precursors) indicating potential electronic communication between the attached organometallic moiety and the porphyrin core. The electrochemistry of these molecules suggests significant electronic interactions between the metallocene and metalloporphyrin in molecules 20 and 24. The crystal structure of the bisferrocenoporphyrin 26, Fe(II) bis[1,2-[Zn(II)-5,10,15,20-tetraphenylporphyrinato]-3-methyl-cyclopentadienide], was dete...
Peptidomics of Cpefat/fat mouse hypothalamus and striatum: effect of chronic morphine administration.

Chronic morphine administration is known to affect several neuropeptide systems, and this could contribute to the behavioral effects of opiates. To quantitate global changes in neuropeptide levels upon chronic morphine administration, we took advantage of a method that allows selective isolation of neuropeptides from brains of mice lacking carboxypeptidase E (Cpefat/fat mice), a critical enzyme in the generation of many neuroendocrine peptides. We used a differential labeling procedure with stable isotopic tags and mass spectrometry to quantitate the relative changes in a number of hypothalamic and striatal peptides in Cpefat/fat mice chronically treated with morphine. A total of 27 distinct peptides were detected in hypothalamus and striatum. Of these, 27 were identified by mass spectrometry-based sequencing, 1 was tentatively identified by the mass and charge, and 9 were not identified. The identified peptides included fragments of proenkephalin, prothyrotropin-releasing hormone, secretogranin II, chromogranin A and B, protachykinin B, provasopressin, promelanin concentrating hormone, and pro-SAAS. Upon morphine administration, although the levels of most of the peptides were unaltered (within a factor of 1.3 to 0.7 compared with saline control), the levels of a small number of peptides did show consistent changes (increased or decreased by 1.3-fold or more) in hypothalamus and/or striatum. Taken together, these results provide interesting insights into endogenous neuropeptide systems that are modulated by morphine and suggest further experiments to link candidate peptides with long-term effects of morphine.
Finding the Right Consumers for Thermal Demand-Response: An Experimental Evaluation

For demand-side management programs concerned with heating, ventilation, and air conditioning (HVAC) energy consumption, smart meter data collected at the whole-premise level has recently been used to decompose usage into its HVAC and non-thermal components, which are typically not separately monitored. In this paper, we study the extent to which program design and decisions based on models using whole-home energy consumption differ from decisions made with full knowledge of appliance-level end-use patterns. We develop a model assessment methodology for the case when model results are used to rank consumers by their potential for thermal demand-response. For this, we compare rankings of consumers in two scenarios—first, when only the aggregate outcome of the top consumers matters, then when the relative ordering of the consumers is important. We illustrate our methodology using two individual consumption models that extract thermal (temperature-sensitive) and occupant-driven components from single-point source smart meter data. Moreover, we discuss how a demand response program that selects the consumers with the most potential for energy reduction based on model results may achieve similar results as in the ideal case when separately monitored HVAC data is used.

The cultural capital of Sofia Coppola’s The Bling Ring (2013): branding feminine celebrity in Los Angeles

ABSTRACTBased on an analytical study of Sofia Coppola’s 2013 film The Bling Ring, this article analyses the political economy of celebrity culture through the film’s portrayal of Los Angeles as the cradle of fame, questioning the power structure behind the commodification of gender as a cultural construct. The Bling Ring exploits celebrity culture through the incorporation of feminine celebrities as brands to be consumed, illustrating a capitalist mode of production that Sofia Coppola endorses by turning her feminine auteurist style into a brand.
SU-B-BRA-04: An Administrators Perspective on the Value of Medical Physics

In the current rapidly changing Healthcare environment, many groups are competing for limited resources. How can medical physicists position themselves to be a relevant stakeholder in the discussion of how those resources are allocated Our value goes beyond what can be shown in a business plan and is heavily involved with safety and quality. Three areas will be explored: 1. What is our value? 2. Who needs to receive that message? 3. How do we communicate that message? To help frame the discussion in terms of how other stakeholders may view the value of medical physicists, a physician and an administrator will present their perspective. Lastly, a multidisciplinary panel will present real life examples of strategies that can be utilized today to establish the value of medical physicists. The presentation of these examples will lead into an interactive question and answer time. V. Willcut, I work for Elekta. There was no research associated with this talk.
Security cannot be measured

Abstract Which of the following is more secure: Windows, Mac OS X, or the White House? All of them have been broken into. They all have security features. A lot of money has been spent on making them secure (some of that money was better spent in some places than in others). They also serve different purposes and have different designs. So which is it? Which is more secure? Or is that a fair comparison at all?
A quasi-continuum thermomechanical model for phonon damping analysis of single crystal silicon nano-resonators

Abstract In this paper, we study phonon-mediated intrinsic damping in single crystal silicon nano-resonators where the phonon transport is of partial ballistic and partial diffusive nature. For this purpose, we present a quasi-continuum thermomechanical model that accounts for both thermoelastic and Akhiezer energy dissipation mechanisms. In the model, the linearized frequency-dependent phonon Boltzmann transport equation (BTE) is coupled with continuum elasticity equations via phonon modulation theory. The model is implemented numerically by using the finite element and finite volume methods for calculating the damping ratio and quality factor of nano-resonators under forced vibration. Both flexural and axial motions are considered for single crystal silicon nano-resonators with different sizes and frequencies. The numerical results obtained from the quasi-continuum thermomechanical model are compared with those obtained from molecular dynamics simulations.
Two new synonyms in Heteranthera (Pontederiaceae, Commelinales)

A brief discussion on the morphology and affinities of Heteranthera s.l. is given, along with the designation of lectotypes for the two new transfers.
Radical new paradigm for heme degradation in Escherichia coli O157:H7.

All of the heme-degrading enzymes that have been characterized to date require molecular oxygen as a cosubstrate. Escherichia coli O157:H7 has been shown to express heme uptake and transport proteins, as well as use heme as an iron source. This enteric pathogen colonizes the anaerobic space of the lower intestine in mammals, yet no mechanism for anaerobic heme degradation has been reported. Herein we provide evidence for an oxygen-independent heme-degradation pathway. Specifically, we demonstrate that ChuW is a radical S -adenosylmethionine methyltransferase that catalyzes a radical-mediated mechanism facilitating iron liberation and the production of the tetrapyrrole product we termed “anaerobilin.” We further demonstrate that anaerobilin can be used as a substrate by ChuY, an enzyme that is coexpressed with ChuW in vivo along with the heme uptake machinery. Our findings are discussed in terms of the competitive advantage this system provides for enteric bacteria, particularly those that inhabit an anaerobic niche in the intestines.
Dosimetric effects of deep inspiration breath hold for radiation treatment of esophageal cancer based on tumor location.

173Background: Deep inspiration breath hold (DIBH) has been shown to reduce heart and lung doses in radiation treatment of breast cancer and lymphoma. We investigated its application for treatment of esophageal cancer. Methods: Five patients who had DIBH simulation for diagnoses with chest scans were studied. Patients were simulated supine with 2 CT scans each: free breathing (FB) and DIBH using surface infrared markers. The patients were contoured using standard volumes as per RTOG 1010, including a 45 Gy planning target volume (PTV). Both a mid-esophagus and distal PTV were created for each of the model patients, by contouring 5 cm tumor volumes at the level of the carina and gastroesophageal junction. Normal structures were contoured as well. For distal tumors, the celiac nodes were covered electively as per RTOG 1010. Uniform three dimensional conformal radiotherapy plans were generated and normalized to provide 100% dose coverage to 95% of the PTV. Dose volume histograms were generated and evaluated....
Trends in spectral analysis: higher order and cyclic statistics

Signal processing problems dealing with linear non-Gaussian signals, nonlinearities, and nonstationarities, cannot be addressed completely using time-invariant second-order statistical descriptors. Traditional correlation and spectral analysis are currently generalized to higher-order moments, cumulants, and polyspectra. At the same time there is an effort to cope with structured nonstationarities and in particular with cyclostationary processes which are signals exhibiting periodicity in their statistical behavior. A critical overview of higher-order and cyclic spectral analysis is attempted herein with emphasis on statistical signal processing aspects. Major advances and limitations are described along with some directions for future research.
Declining Prime-Age Male Labor Force Participation: Why Demand- and Health-Based Explanations are Inadequate

Observers of all ideological persuasions are concerned about the long-term decline in male labor force participation. Explanations for this drop fall into one of three categories. Some analysts, including those in the Obama administration’s Council of Economic Advisers, argue that declining demand for less-skilled labor among employers — resulting in lower pay for the same work — has caused more men to drop out of the labor force. Others claim that fewer men are able to work owing to deteriorating health conditions. This paper highlights the flaws in these two accounts and, in so doing, makes the case for a third explanation: that declining interest in work has reduced labor supply.
Decreased coronary arteriolar response to KCa channel opener after cardioplegic arrest in diabetic patients.

We have recently found that diabetes is associated with the inactivation of the calcium-activated potassium channels (KCa) in endothelial cells, which may contribute to endothelial dysfunction in diabetic patients at baseline. In the current study, we further investigated the effects of diabetes on coronary arteriolar responses to the small (SK) and intermediate (IK) KCa opener NS309 in diabetic and non-diabetic patients and correlated that data with the changes in the SK/IK protein expression/distribution in the setting of cardioplegic ischemia and reperfusion (CP) and cardiopulmonary bypass (CPB). Coronary arterioles from the harvested right atrial tissue samples from diabetic and non-diabetic patients (n = 8/group) undergoing cardiac surgery were dissected pre- and post-CP/CPB. The in vitro relaxation response of pre-contracted arterioles was examined in the presence of the selective SK/IK opener NS309 (10−9–10−5 M). The protein expression/localization of KCa channels in the harvested atrial tissue samples, coronary microvessels, and primary cultured human coronary endothelial cells were assayed by Western blotting and immunohistochemistry. The relaxation response to NS309 post-CP/CPB was significantly decreased in diabetic and non-diabetic groups compared to their pre-CP/CPB responses, respectively (P 0.05). Our results suggest that diabetes further inactivates SK/IK channels of coronary microvasculature early after CP/CPB and cardiac surgery. The lack of diabetic changes in SK/IK protein abundances in the setting of CP/CPB suggests that the effect is post-translational. This alteration may contribute to post-operative endothelial dysfunction in the diabetic patients early after CP/CPB and cardiac surgery.
BIOCHEMICAL AND ULTRASTRUCTURAL ALTERATION OF RAT LIVER BY PHOTOHEPTACHLOR

ABSTRACT Treatment of male rats with photoheptachlor (24-hr LD-50 = 3.4 mg/kg) at 1 mg/kg or lower dosages for several weeks caused about 27% increase in liver weight to body wt ratios. Microsomal cytochrome P-450 was increased by about 20%, while ratios of 0- and N-demethylations of, respectively, p-nitroanisole (PNA) and aminopyrine (AP) by MFO were almost doubled. Ethylisocyanide caused a two-fold increase in the ratio of 455 nm to 430 nm peak. The AHH and 7-ethoxycoumarin deethylation were increased only slightly. The specific rate of aniline (A) hydroxylation almost doubled at lower dosages but was normal at higher dosages. Electron microscopic observations revealed the proliferation of smooth endoplasmic reticulum similar to that caused by other cyclodienes and barbiturates. There was an increase in the multilaminated myelin bodies and a decrease in glycogen. Lysosomes were not present in the treated hepatocytes.
Gravitation experiments at Stanford

The experimental situation in post-Newtonian gravitation is briefly reviewed in order to reexamine the extent to which experiment supports or refutes general relativity. A description is given of the equivalence principle project, the gyroscope experiment, and the search for gravity waves. It is noted that even though some doubt has been cast on the value of the perihelion advance and the gravitational redshift as precise tests of general relativity in the past few years, many competing theories have been ruled out; in particular, the results from the Viking mission significantly reduce the credibility of the Brans-Dicke theory (Brans and Dicke, 1961). The dimensionless constant omega in this theory is now forced to exceed 50, while the value originally proposed was 6 (omega being infinity in general relativity). It is noted that the gyro experiment described is capable of putting much tighter limits on this parameter, and together with the other experiments in progress will help place gravitational theory on a firmer experimental footing.
Dynamical insights into the mechanism of a droplet detachment from a fiber

Quantifying the detachment behavior of a droplet from a fiber is important in many applications such as fog harvesting, oil–water separation, or water management in fuel cells. When the droplets are forcibly removed from hydrophilic fibers, the ease of detachment strongly depends on droplet volume and the rate of the process controlled by the applied force. Experiments, conducted on a ferrofluid under magnetic force, as well as continuum level calculations from fluid mechanics have so far been unable to resolve the time-dependent dynamics of droplet detachment and, most importantly, to assess the role of the applied force as the key determinant of the volume of the droplet residue remaining on the fiber after detachment. In the present work, we study the mechanism of water droplet detachment and retention of residual water on smooth hydrophilic fibers using nonequilibrium molecular dynamics simulations. We investigate how the applied force affects the breakup of a droplet and how the minimal detaching force per unit mass decreases with droplet size. We extract scaling relations that allow extrapolation of our findings to larger length scales that are not directly accessible by molecular models. We find that the volume of the residue on a fiber varies nonmonotonically with the detaching force, reaching the maximal size at an intermediate force and associated detachment time. The strength of this force decreases with the size of the drop, while the maximal residue increases with the droplet volume, V, sub-linearly, in proportion to the V2/3.
Enterobacter Infection after Spine Surgery: An Institutional Experience.

Background Gram-negative surgical site infections (SSI) following spine surgery are becoming increasingly more common owing to a broad perioperative antibiotic usage targeting gram-positive organisms. Enterobacter species have been reported to be the most common gram-negative bacteria following spine surgery. Methods We queried our institutional database for Enterobacter SSIs after spine surgery at a single institution from 2009–2016. Relevant demographic, clinical, and operative variables were collected. We compared this cohort to patients who had non-Enterobacter SSI during the same period. Results Enterobacter species were isolated in 16 patients (9 males) diagnosed with SSI after undergoing spine surgery. This group represented 0.2% of all spine cases and 14.5% of all spinal SSIs. Seven patients (43.8%) required multiple irrigations and debridements (I&Ds) (range: 2–8), whereas only 17 of 94 patients (18.1%) with non-Enterobacter SSI required multiple I&Ds (range: 2–5, P = 0.043). Those infected with Enterobacter were associated with higher BMI (37.6 ± 12.7 vs. 31.7 ± 8, P = 0.036), earlier wound dehiscence (14.8 vs. 24.6 days, P = 0.01), polymicrobial infections (37.5% vs. 10.6%, P = 0.012), and longer length of stay (18 days [9.5–31.5] vs. 5 days [3–8], P = 0.01) when compared to non-Enterobacter SSI cohort. At an average of 24.2 months follow-up, all 15 surviving patients were infection free with no further revision surgeries needed. Conclusions Enterobacter SSI cases were associated with higher BMI, earlier wound breakdown, polymicrobial infection and longer length of stay. Nevertheless, with vigilant surveillance and timely I&Ds, these challenging infections can be treated successfully with original implant retention in almost all cases.

A case of Susac syndrome.

Susac syndrome is a readily recognized but often misdiagnosed disorder almost exclusively affecting women in the 20- to 40-year age range. Characterized by the clinical triad of encephalopathy, branch retinal artery occlusions, and sensorineural hearing loss, patients with Susac syndrome are often misdiagnosed with multiple sclerosis (MS) . Unlike MS, however, the disease process extends over a 1- to 2-year period and then goes into remission. This presentation describes the progression of symptoms of a patient eventually diagnosed with Susac syndrome .
(Gordon E. Moore Medal for Outstanding Achievement in Solid State Science and Technology Award Address) Towards Silicon-Based Photonic Integrated Circuits: The Quest for Compatible Light Sources

Light emission from silicon and germanium nanostructures has been of great interest for some time now owing to the need for silicon-based light sources for applications in silicon optoelectronics and photonics. Both silicon and germanium possess indirect band gaps, which makes them very inefficient light emitters. Band gap engineering employing quantum wells, wires, or dots has been proposed as one way to overcome this limitation and, in the past, Si/Ge, Si/SiO2, or Si/SiGe-alloy thin-multilayer nanostructures grown on Si have been produced on this principle, and although light emission with a greatly improved efficiency has been obtained at low temperatures the emission at room temperature is still very weak, because of exciton dissociation. Recent advances in band gap engineering technology have resulted in the development of different systems incorporating one-, two-, and three-dimensionally confined Si-Ge nanostructures that produce bright light in the visible to near infrared. Here, the novel optical properties of various such nanostructures are reviewed.
Endoscopic Techniques in Frontal Sinus Surgery

The frontal sinus is arguably the most challenging paranasal sinus to address surgically. Surgery is technically demanding and carries a higher risk of complications. Postoperative stenosis may necessitate revision surgery. The goals of frontal sinus surgery are to address medically refractory disease effectively while minimizing risks and complications. Clinical indications and expectations of benefit from surgery should be thoughtfully evaluated prior to proceeding with surgery. To perform surgery safely, effectively, and efficiently, the frontal surgeon must commit to mastering knowledge of frontal anatomy and instrumentation. They must develop and hone skills in meticulous tissue handling and commit to zealous postoperative care.
Impact of Nosema maddoxi on the survival, development, and female fecundity of Halyomorpha halys.

Abstract Nosema maddoxi Becnel, Solter, Hajek, Huang, Sanscrainte, & Estep, a microsporidian species native to the United States, has been found infecting the invasive brown marmorated stink bug, Halyomorpha halys (Stal). Microsporidian infections in insects often shorten lifespans, decrease fecundity, prolong development, and stunt growth. This study was conducted to determine the impact of N. maddoxi on H. halys fitness. Adult females (2 doses) and nymphs (1 dose) drank suspensions of N. maddoxi spores to promote infection. Adult females receiving a high dose died faster than the controls. Nosema maddoxi infections impacted female egg production and egg viability at both doses compared with the controls. Infections were transmitted to 34.9% of adult males caged with infected females. As the number of days after inoculation increased, infection intensity (# spores found within an infected individual) for both adult treatments transitioned from low-intensity to high-intensity. Infected nymphs died significantly sooner than the controls. Of the treated nymphs, 55.9% died before molting into the fourth instar and only 26.5% eclosed to adults. Nymphal development rate and size were not impacted by N. maddoxi infection. These results indicate that N. maddoxi infection can negatively impact the lifespan of adult females, female fecundity, egg viability, and nymphal survival, which we hypothesize would negatively impact H. halys population densities.
A site-isolated rhodium-diethylene complex supported on highly dealuminated Y zeolite: synthesis and characterization.

The reaction of Rh(C{sub 2}H{sub 4}){sub 2}(acac) with the partially dehydroxylated surface of dealuminated zeolite Y (calcined at 773 K) and treatments of the resultant surface species in various atmospheres (He, CO, H{sub 2}, and D{sub 2}) were investigated with infrared (IR), extended X-ray absorption fine structure (EXAFS), and {sup 13}C NMR spectroscopies. The IR spectra show that Rh(C{sub 2}H{sub 4}){sub 2}(acac) reacted readily with surface OH groups of the zeolite, leading to loss of acac ligands from the Rh(C{sub 2}H{sub 4}){sub 2}(acac) and formation of supported mononuclear rhodium complexes, confirmed by the lack of Rh-Rh contributions in the EXAFS spectra; each Rh atom was bonded on average to two oxygen atoms of the zeolite surface with a Rh-O distance of 2.19 Angstroms. IR, EXAFS, and {sup 13}C NMR spectra show that the ethylene ligands remained bonded to the Rh center in the supported complex. Treatment of the sample in CO led to the formation of site-isolated Rh(CO){sub 2} complexes bonded to the zeolite. The sharpness of the CO bands in the IR spectrum gives evidence of a nearly uniform supported Rh(CO){sub 2} complex and, by inference, the near uniformity of the mononuclear rhodium complex with ethylene ligands from whichmore » it was formed. The supported complex with ethylene ligands reacted with H{sub 2} to give ethane, and it also catalyzed ethylene hydrogenation at 294 K.« less
Comparison of Compliance and Estimation Procedures for Calculating J-Integral Values

Methods for J-integral fracture toughness testing are new and, therefore, not well established. Compliance methods developed by Begley and Landes provide accurate data but require extensive specimen testing and analysis. Estimation procedures that allow the calculation of J c from a single test are convenient to use but are of unknown accuracy. In order to compare these two techniques, compact tension specimen test data from seven alloys were analyzed by both methods. A comparison of the results showed that estimated values of J c by the Rice, Paris, and Merkle equation agreed best with compliance data when a/w > 0.75 but always tended to underestimate J c . An equation derived from an improved analysis by Merkle and Corten tended to overestimate J c .
Parental Support for Sexuality Education and Expression Among Adults with an Intellectual Disability

Sexuality expression and experiences are an often-ignored component of health and well-being for adults with intellectual disabilities (ID). Adults with ID have gaps in their sexuality education, and experience restrictions from parents and caregivers exploring their sexuality. However, parental control does not deter adults with ID from desiring sexual experiences, and instead often leads to secretive and potentially exploitative relationships. Although this pattern is clear, we lack an understanding of the impact of parental attitudes on sexuality education and expression for adults with ID. The current study examines parental experiences attending to sexuality education and sexuality expression for adults with ID compared to their typically developing adult siblings. A mixed methods design was used including an online survey with 50 parents nationwide, and follow-up phone/video conferencing interviews with a subset of 20 parents. Findings from this study indicate that parents are more engaged with adults with ID and struggle to determine the appropriate level of sexuality education they should be providing to individuals with ID. Findings add to our understanding of the important role of the parent, and provides insight into training to support parents as they navigate these experiences.
Undergraduate Health Informatics Education

Undergraduate health informatics education is paramount to the continuous expansion of the informatics field. Education in health informatics has predominantly focused on master’s and doctoral-level education, as well as clinical subspecialty training. Currently, there are core competencies for graduate health informatics education that can be used as guidance for existing programs revising their curricula or emerging programs starting a new program. However, there is limited knowledge around the structure and content of undergraduate health informatics education. In this chapter, we will highlight the gap in knowledge, summarize the need for undergraduate structure, discuss foundational domains, using Miller’s Pyramid as adapted for health informatics, and provide recommendations on core concepts for undergraduate health informatics education.
Phylogeny and biogeography of some Cretaceous spatangoid echinoids with special emphasis on taxa from the Western Interior Seaway

Members of the echinoid order Spatangoida, a highly diverse and abundant marine invertebrate clade, were important denizens of the Cretaceous Western Interior Seaway (WIS), an epicontinental seaway that divided North America in two during an interval of greenhouse conditions between roughly 100 and 65 million years ago. A phylogenetic analysis of spatangoids was conducted using a character matrix of 32 characters from 21 species. Species that occur in the WIS were considered comprehensively, and species from other regions such as South America, Europe, and North Africa were also incorporated into the analysis. Phylogenetic patterns retrieved are largely congruent with preexisting family-level classifications; however, species within several genera, especially Hemiaster and Heteraster, need to be reassigned so that classification better reflects phylogeny. The genera Washitaster and Heteraster are closely related, as are Mecaster, Palhemiaster, and Proraster; Pliotoxaster, Macraster, and Hemiaster; and Micraster and Diplodetus. Biogeographic patterns were also considered using the phylogeny, and several episodes of vicariance and range expansion were identified. These were possibly related to some of the various major episodes of sea-level rise and fall during the Cretaceous. In particular, Valangian–mid-Aptian regressions may have caused vicariance within Heteraster and Washitaster while other early spatangoid vicariance may be related to regressions during the late Aptian–early Cenomanian. Further, vicariance caused by regressions during the mid-Cenomanian–Maastrichtian may have driven diversification within Micraster and Diplodetus. Last, transgressions during the late Aptian–early Cenomanian seem to have spurred prominent range expansions in Mecaster and Hemiaster.
Dominant vector changes during early wavebreak/spiral wave (Wiggers stage 1) in ventricular fibrillation: insights from the analysis of 100 electrophysiology studies

To describe electrocardiographic vector patterns during early VF transition (Wiggers stage 1). In 100 electrophysiology studies with VF induction, the first 3 beats of VF were analyzed in lead I for left/right axis (LA/RA), V1 for left/right bundle (LB/RB), and aVF for superior/inferior axis (SA/IA). Correlation with demographic/clinical factors was performed using regression analyses and mixed effect modeling. VF initiated more likely with LA than RA (P < 0.001) and LB than RB (P = 0.04) suggesting original wavebreak in the right ventricle. The 3-dimensional morphology changed in 69% of VF during the first 3 beats, with predominant increase in RB, suggesting a transition of QRS-originating vector to septum/left ventricle. Conservation of morphology (31%) was favored by initial RB (P = 0.002) and LA morphology (P = 0.01). Initiation of VF with LA vs RA was more likely in African-Americans (P = 0.016) and increasing age (P = 0.032). Ischemic cardiomyopathy favored VF initiation with RB 6.7-fold (P = 0.025), possibly linking LV myocardial scar to initial VF wavebreak location. Male gender and ischemic cardiomyopathy prolonged time-to-loss of predominant vector by 119% (P = 0.002) and 71% (P = 0.017), respectively, suggesting more preserved anatomic/functional reentry. The predominant QRS vectors during early Wiggers stage 1 VF are not random and suggest an initial wavebreak more commonly in the right ventricle, followed by a transitional shift to the septum/left ventricle. Ethnicity, male gender, age, and co-morbidities result in directional preservation of initiating VF vectors possibly due to myocardial mass/fibrosis. Findings may allow new treatment/ablation approaches.

Exploring Integrated Environmental Viral Surveillance of Indoor Environments: A comparison of surface and bioaerosol environmental sampling in hospital rooms with COVID-19 patients

The outbreak of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) has dramatically transformed policies and practices surrounding public health. One such shift is the expanded emphasis on environmental surveillance for pathogens. Environmental surveillance methods have primarily relied upon wastewater and indoor surface testing, and despite substantial evidence that SARS-CoV-2 commonly travels through space in aerosols, there has been limited indoor air surveillance. This study investigated the effectiveness of integrated surveillance including an active air sampler, surface swabs and passive settling plates to detect SARS-CoV-2 in hospital rooms with COVID-19 patients and compared detection efficacy among sampling methods. The AerosolSense active air sampler was found to detect SARS-CoV-2 in 53.8% of all samples collected compared to 12.1% detection by passive air sampling and 14.8% detection by surface swabs. Approximately 69% of sampled rooms (22/32) returned a positive environmental sample of any type. Among positive rooms, ~32% had only active air samples that returned positive, while ~27% and ~9% had only one or more surface swabs or passive settling plates that returned a positive respectively, and ~32% had more than one sample type that returned a positive result. This study demonstrates the potential for the AerosolSense to detect SARS-CoV-2 RNA in real-world healthcare environments and suggests that integrated sampling that includes active air sampling is an important addition to environmental pathogen surveillance in support of public health.
Microscopic Evaluation of Direct Fecal Smears in the Assessment of Bovine Neonatal Enteritis

Enteritis, or calf scours, is the most common clinical disease of pre-weaned dairy calves and accounts for nearly 60% of pre-weaned dairy calf mortality. Multiple nutritional factors and infectious agents are associated with calf scours. The lack of agent specific clinical signs makes it difficult to determine presumptive etiologies and prescribe specific treatment. Changes in the fecal microflora and the presence of fecal white blood cells are observed in calves with enteritis. The hypothesis for this study was that alterations in the fecal microflora and/or the presence of fecal white blood cells are related to enteric disease signs in dairy calves and may provide useful clinical information. The objectives of this study were to evaluate fecal direct smears for the presence of enteric microflora and fecal white blood cells and compare this information with the presence of enteric disease signs in dairy calves.
Caption-occlusion severity judgments across live-television genres from deaf and hard-of-hearing viewers

Prior work has revealed that Deaf and Hard of Hearing (DHH) viewers are concerned about captions occluding other onscreen content, e.g. text or faces, especially for live television programming, for which captions are generally not manually placed. To support evaluation or placement of captions for several genres of live television, empirical evidence is needed on how DHH viewers prioritize onscreen information, and whether this varies by genre. Nineteen DHH participants rated the importance of various onscreen content regions across 6 genres: News, Interviews, Emergency Announcements, Political Debates, Weather News, and Sports. Importance of content regions varied significantly across several genres, motivating genre-specific caption placement. We also demonstrate how the dataset informs creation of importance-weights for a metric to predict the severity of captions occluding onscreen content. This metric correlated significantly better to 23 DHH participants' judgements of caption quality, compared to a metric with uniform importance-weights of content regions.
Effect of COVID-19 on training and mental health of oral medicine residents in North America.

Objective The objective of this study was to assess resident and faculty perception of the effect of the coronavirus disease 2019 pandemic on the training experience, education, and psychological well-being of oral medicine (OM) residents. Study Design An anonymous 16-item online questionnaire was e-mailed to faculty and residents of all Commission on Dental Accreditation–accredited OM residency programs in North America. Survey questions asked about the pandemic's effect on resident educational, clinical, and research activities and the well-being of the residents. Survey data were collected using Qualtrics XM. Results Forty participants (52.5% residents and 47.5% faculty members) responded to the survey. Regarding the effect on clinical activities, 67.5% reported 50% or less reduction in patient volume seen by residents at its worst during the pandemic. With respect to educational activities, most reported a complete switch of didactic training (85.3%), academic examinations (60%), and off-site resident rotations (45%) to a virtual platform. Research activities were affected the most; 55% reported complete cessation for some time. Thirty-three percent perceived a negative effect, 18% perceived no effect, 11% perceived a positive effect, and 38% were unsure regarding the effect of coronavirus disease 2019 on resident morale. Despite the interruptions in the clinical, research, and educational activities, 62.5% expected on-time resident graduation. Conclusion Despite constraints due to the pandemic, OM residency programs successfully continued clinical activities, didactic training, and research productivity through virtual means and a hybrid delivery care model while supporting their residents’ morale.
