Sedimentation and volcanism in an Oligocene-Miocene intra-oceanic are and fore-are, southwestern Viti Levu, Fiji

Rocks belonging to the Lower Oligocene to Middle Miocene Wainimala Group in southwestern Viti Levu can be divided into an are assemblage, representing the axial part of a volcanic are, and a basinal assemblage, representing the trenchward flank of the are and the inner part of the fore-are basin. The are assemblage consists mainly of volcaniclastic rudites and lava flows, with minor shallow-water limestones, and is intruded by Mid- to Late Miocene gabbro and tonalite stocks. The basinal assemblage to the north is floored by part of an earlier, Eocene to Lower Oligocene are. The lower part of this assemblage includes volcaniclastic rudites representing the dispersal aprons of major volcanic edifices to the trenchward of the are axis, and basaltic lavas and fissure-fed rhyolite lava domes and breceia ridges erupted in deeper water away from these centres. The rhyolites are directly related to the acidic members of a dense, compositionally bimodal dyke swarm that intrudes the underlying earlier are rocks, recording substantial crustal extension. The basinal volcanic rocks are interbedded with and overlain by a sequence of pelagic carbonates, thin-bedded epiclastic turbidites, and acidic tuffs. The basinal succession evolved from an intra-are to an inner fore-are setting as volcanism within the assemblage died away in the Early Miocene. In the late Early Miocene increased uplift and emergence of the are massif increased the sediment yield to the fore-are basin, resulting in the deposition of thicker-bedded, coarser-grained turbidites.

A first functional current excited planar rotational magnetic micromotor

Complete integration and successful testing of a planar rotational magnetic micromotor have been demonstrated. The configuration is that of a three-phase variable reluctance stepping motor with 6 stator poles and 4 rotor poles. Stator and rotor heights of up to 300 mu m are available and rotor diameters of 285 mu m and 423 mu m were tested. Maximum rotational speeds which have been achieved with open loop excitation exceed 30000 rpm and show no change with operation in vacuum. After testing to more than 5*10/sup 7/ rotation cycles, deviations from initial operation are not observed. Vertical reluctance forces are used to levitate the rotor up to 50 mu m over the substrate. Position signals are available via integrated photodiodes which allow the rotor speed to be monitored and provide the groundwork for an active closed-loop system. >
An analysis of nonlinear behavior in delta - sigma modulators

This paper introduces a new method of analysis for deltasigma modulators based on modeling the nonlinear quantizer with a linearized gain, obtained by minimizing a mean-square-error criterion [7], followed by an additive noise source representing distortion components. In the paper, input signal amplitude dependencies of delta-sigma modulator stability and signal-to-noise ratio are analyzed. It is shown that due to the nonlinearity of the quantizer, the signal-to-noise ratio of the modulator may decrease as the input amplitude increases prior to saturation. Also, a stable third-order delta-sigma modulator may become unstable by increasing the input amplitude beyond a certain threshold. Both of these phenomena are explained by the nonlinear analysis of this paper. The analysis is carried out for both dc and sinusoidal excitations.
Homogenization, lyophilization or acid-extraction of meat products improves iron uptake from cereal-meat product combinations in an in vitro digestion/Caco-2 cell model

The effect of processing (homogenization, lyophilization, acid-extraction) meat products on iron uptake from meat combined with uncooked iron-fortified cereal was evaluated using an in vitro digestion/Caco-2 cell model. Beef was cooked, blended to create smaller meat particles, and combined with electrolytic iron-fortified infant rice cereal. Chicken liver was cooked and blended, lyophilized, or acid-extracted, and combined with FeSO4-fortified wheat flour. In the beef-cereal combination, Caco-2 cell iron uptake, assessed by measuring the ferritin formed by cells, was greater when the beef was blended for the greatest amount of time (360 s) compared with 30 s (P < 0.05). Smaller liver particles (blended for 360 s or lyophilized) significantly enhanced iron uptake compared to liver blended for 60 s (P < 0.001) in the liver-flour combination. Compared to liver blended for 60 s, acid-extraction of liver significantly enhanced iron uptake (P = 0.03) in the liver-flour combination. Homogenization of beef and homogenization, lyophilization, or acid-extraction of chicken liver increases the enhancing effect of meat products on iron absorption in iron-fortified cereals.
On the theory of advective effects on biological dynamics in the sea. II. Localization, light limitation, and nutrient saturation

The theory of advective effects is extended to include localization effects, due both to the attenuation of light with depth in the ocean and to nutrient transport into the euphotic zone of finite duration in time and/or over a limited horizontal domain. Nutrient uptake is also generalized to nonlinear Michaelis–Menten kinetics. The characteristic curves are solved for explicitly, and a symbolic general solution is obtained for arbitrary biological dynamics. Some exemplary results are presented for the effect of light, nutrient, and grazing limitations on primary productivity in an NPZ –model. The theory is now applicable to further studies of more realistic oceanic processes.
Spatially extended K i λ7699 emission in the nebula of VY CMa: kinematics and geometry

Long-slit echelle spectra reveal bright extended emission from the K I λ7699 resonance line the reflection nebula surrounding the extreme red supergiant VY Canis Majoris. The central star has long been known for its unusually bright K I emission lines, but this is the first report of intrinsic emission from K I in the nebula. The extended emission is not just a reflected spectrum of the star, but is due to resonant scattering by K atoms in the outer nebula itself, and is therefore a valuable probe of the kinematics and geometry of the circumstellar environment of VY CMa. Dramatic velocity structure is seen in the long-slit spectra, and most lines of sight through tle nebula intersect multiple distinct velocity components. A faint 'halo' at large distances from the star does appear to show a reflected spectrum, however, and suggests a systemic velocity of +40 km s -1 with respect to the Sun. The most striking feature is blueshifted emission from the filled interior of a large shell seen in images; the kinematic structure is reminiscent of a Hubble flow, and provides strong evidence for asymmetric and episodic mass loss due to localized eruptions on the stellar surface .
Effect of microcracking on the measured moduli of bulk YBa 2 Cu 3 O x

Elastic moduli of both as-hot-pressed and oxygenated YBa{sub 2}Cu{sub 3}O{sub {ital x}} were measured, under isostatic pressures up to 1 GPa, using a combination of strain gage and ultrasonic techniques. Pressurization of the as-hot-pressed samples caused no significant change in moduli; however, pressurization of the oxygenated sample produced a 5-fold increase in bulk modulus. The results show that the significant decreases in moduli between the as-hot-pressed and the oxygenated state were due to extensive microcracking, of an extremely fine nature, that occurred during the oxygenating sequence.
Direction of arrival (DOA) estimation using a transformation matrix through singular value decomposition

In this paper we present how we choose the proper number of virtual array elements from the real array for direction of arrival (DOA) estimation using a conformal hemispherical real array and a single snapshot of the data. The number of virtual array is achieved by using singular value decomposition (SVD) of a real array manifold and the concept of the interpolation techniques. Then, the transformation matrix is generated from both the virtual array manifold and the real array manifold. A numerical simulation has been made to illustrate of the proposed approach. We estimate direction of arrival (DOA) of signals using the matrix pencil method.
Modification of formants in the line spectrum domain

A method for modifying formant locations and bandwidths directly in the line spectrum domain is developed. This method is based on first-order approximations between different representations of the linear prediction spectrum and does not require finding the roots of the prediction polynomial. In addition, this method is less sensitive to pole interaction problems associated with direct pole modification.
Role of oxidants in microbial pathophysiology.

Reactive oxidant species (superoxide, hydrogen peroxide, hydroxyl radical, hypohalous acid, and nitric oxide) are involved in many of the complex interactions between the invading microorganism and its host. Regardless of the source of these compounds or whether they are produced under normal conditions or those of oxidative stress, these oxidants exhibit a broad range of toxic effects to biomolecules that are essential for cell survival. Production of these oxidants by microorganisms enables them to have a survival advantage in their environment. Host oxidant production, especially by phagocytes, is a counteractive mechanism aimed at microbial killing. However, this mechanism may be contribute to a deleterious consequence of oxidant exposure, i.e., inflammatory tissue injury. Both the host and the microorganism have evolved complex adaptive mechanisms to deflect oxidant-mediated damage, including enzymatic and nonenzymatic oxidant-scavenging systems. This review discusses the formation of reactive oxidant species in vivo and how they mediate many of the processes involved in the complex interplay between microbial invasion and host defense.

Everolimus-Eluting Coronary Stents for Patients With Chronic Kidney Disease: What Explains the Magic?

Familial inappropriate sinus tachycardia: a new chapter in the story of HCN4 channelopathies.

This editorial refers to ‘A gain-of-function mutation in the cardiac pacemaker HCN4 channel increasing cAMP sensitivity is associated with familial Inappropriate Sinus Tachycardia’, by M. Baruscotti et al ., doi:10.1093/eurheartj/ehv582 The sinoatrial node (SAN) contains a small number of pacemaker cells (PCs), specialized cardiomyocytes whose automatic firing triggers each heart beat. Autonomic and endocrine modulation of PC automaticity enables precise neurohormonal regulation of heart rate (HR) in accordance with physiological demand. While the cellular mechanisms that underlie HR regulation are complex and still actively debated, several critical molecular players have been identified and cloned over the past few decades.1 Among the most important are the hyperpolarization-activated, cyclic nucleotide-gated (Hcn) ion channels, which conduct an inward cation current that is activated by hyperpolarization and modulated by cAMP binding. Hcn current, also known as funny current, contributes to early diastolic depolarization in PCs, and hence to firing rate. Of the Hcn channel isoforms, Hcn4 is the most important for regulation of mammalian heart rhythm. Hcn4 is expressed in a steep gradient that parallels the gradient of automaticity among different types of cardiomyocyte: SAN PCs exhibit high level Hcn4 expression, atrioventricular nodal myocytes exhibit moderate expression, the His–Purkinje system exhibits lower expression, and there is minimal expression in working atrial and ventricular cardiomyocytes.2 Heart-specific Hcn4 deletion in adult mice causes severe bradycardia and death,3 and loss-of-function mutations in human Hcn4 cause familial sinus bradycardia, a rare genetic arrhythmia syndrome marked by early-onset sinus node dysfunction and bradycardia.4 Since the original description of familial sinus bradycardia,5 several other Hcn4-associated cardiac syndromes have emerged, including atrioventricular block,6 early-onset atrial fibrillation,7 Brugada syndrome,8 prolonged …
Pulmonary Hyaline Membranes and Vascular Anomalies of the Lung: The "Lausanne Baby"

A very interesting brief case report, entitled "Pulmonary Hyaline Membranes and Vascular Anomalies of the Lung," was published in Pediatrics by Bozic. This case is commonly referred to as the "Lausanne baby" and is used by many to support the hypothesis that hyaline membrane disease is primarily related to reduced pulmonary blood flow. Although there are good reasons from observations in both man and animal to implicate reduced pulmonary blood flow as an important factor in the pathophysiology of hyaline membrane disease, we do not believe the "Lausanne baby" can be used to support this hypothesis.
Modeling air-core permanent-magnet linear generators in free-rotating devices

This paper details modeling to support the design of an air-core permanent-magnet-based energy-harvest system for use within an in-pipe mobile water-quality sensor. A challenge presented by this system is that the electrical and mechanical dynamics of the device are strongly coupled. Recently, a rigorous electrical/mechanical model was established to address this challenge in order to determine expected energy harvest, given the geometric/material parameters and electrical/mechanical inputs. An initial focus herein is the development of parameter measurement techniques for purposes of model validation. Subsequently, based upon hardware results, an alternative friction model is derived and utilized to explore the effect of friction on expected energy harvest.
The Journal of Knee Surgery Reports

The Journal of Knee Surgery has ever acknowledged the importance of publishing high-quality case reports. Almost 2 years ago, one special supplement of this journal aimed this specialmodality of publication. As the number of submissions continued to increase, in 2014, a sister periodical was launched to address this purpose, the Journal of Knee Surgery Reports. The main scope of the new journal is to offer a premium outlet for authors willing to share interesting and welldocumented clinical cases related to knee pathology. We believe that this is a true opportunity to present rare clinical conditions, original decision-making approaches, creative solutions, and ultimate outcomes that make every case unique. In this first printed edition, we collected 14 articles, which were published online first. A variety of topics have been covered, from rare knee tumor presentations to compartment syndrome following total knee replacement. Wewould like to thank all authors, reviewers, and editorial board members for their relevant contributions to the first printed issue of this journal. To our readers, we would like to wish a rewarding experience. The Journal of Knee Surgery Reports aims to be a reference for excellence in knee-related clinical cases. To accomplish this goal, we do invite you to join us and share your expertise with a large community of knee surgeons. Be our guest and collaborator. You are very welcome to the Journal of Knee Surgery Reports. Editorial

Teaching NeuroImages: Medullary lesions causing dysphagia in Leigh/MELAS overlap syndrome

A 16-year-old boy with known Leigh/mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes (MELAS) overlap syndrome ( MTND5 T12706C mutation) developed worsening dysphagia. Examination revealed reduced palatal movements and dysarthria. MRI showed prior strokes, basal ganglia lesions, and new right > left medullary lesions (figure). He was discharged on gastrostomy tube feeds to decrease aspiration risk. Leigh syndrome is a neurodegenerative mitochondrial disorder with necrotizing basal ganglia and brainstem lesions.1 MTND5 mutation causes rare Leigh/MELAS overlap syndrome with clinical and neuroradiologic characteristics of both.2 Though dorsal medullary lesions are common in Leigh syndrome, they are rarely asymmetric or associated with dysphagia.1
Photochemical generation of manganese(IV)-oxo porphyrins by visible light photolysis of dimanganese(III) μ-oxo bis-porphyrins

Abstract Visible light photolysis of dimanganese(III) μ-oxo bis -porphyrins, [Mn III (Por)] 2 O, was studied in three porphyrin systems with different electronic structures. Direct conversion of manganese (III) μ-oxo dimers to manganese(IV)-oxo porphyrins plus manganese(III) products has been observed in benzene solution upon light irradiation. The spectral signature of Mn IV (Por)(O) was further confirmed by production of the same species in the known experiment of the Mn III (Por)Cl with PhI(OAc) 2 . Continuous irradiation of dimanganese(III) μ-oxo bis -porphyrins in the presence of pyridine or triphenylphosphine gave rise to the formation of Mn II (Por)(Py) or Mn II (Por)(PPh 3 ) which were stable to be detected. A photo-disproportionation mechanism similar to that for diiron(III) μ-oxo bis -porphyrins was proposed to explain above photochemical behaviors of the three dimanganese(III) μ-oxo bis -porphyrins.
Extremal problems for cycles in graphs

In this survey we consider extremal problems for cycles of prescribed lengths in graphs. The general extremal problem is cast as follows: if \(\mathcal{C}\) is a set of cycles, determine the largest number of edges \(\mathrm{ex}(n,\mathcal{C})\) in an n-vertex graph containing no cycle from \(\mathcal{C}\). The survey contains short proofs of various known theorems, including the even cycle theorem of Erdős and Bondy and Simonovits. We also give proofs of new results and conjectures of Erdős on cycles, for instance, we find new sufficient conditions for cycles of length l modulo k and for long cycles in triangle-free graphs of large chromatic number. We also review proofs of some conjectures of Erdős on the distribution of the lengths of cycles in graphs, as well as related problems on chromatic number and girth, counting graphs without short cycles, and extensions to cycles in uniform hypergraphs. Throughout the survey, we include a number of conjectures and open problems.
THE CHURCH AS EMBODIMENT AND EXPRESSION OF COMMUNITY ON UJELANG AND ENEWETAK, MARSHALL ISLANDS

The church as a culturally constructed location is constantly "unmade and remade" on Ujelang and Enewetak Atolls (Marshall Islands) with semantic values tied to wider social and historical changes. Stories about the original church represent it as a sacred site forming the physical, moral, and cosmogenic center of the Enewetak community. During World War 11, Japanese military rule transformed the church into a location of resistance. During postwar exile to Ujelang Atoll, the village-centered church became a site where solidarity-enhancing practices allowed the community to confront isolation and suffering. A new church, built in 1978 as a symbol of reinvigorated identity, was abandoned within two years with repatriation to Enewetak Atoll, where church and town "center" were displaced and cohesive elements of community were unraveling. A foreign upstart church made the 1990s a contentious time as churches, new and old, were refashioned as physical and sociosemantic sites of significance in the ongoing negotiation of communal identity.
On-Farm Corn and Soybean Planter Trials

Corn and soybean planting is one of the most critical operations of the season. Operating the planter with the proper soil conditions for proper placement of the seed to obtain the correct seed-soil contact is important to optimize yields and reduce problems later in the season with plant and root growth. As corn and soybean seed prices continue to rise, and grain prices fall, it is important for farmers to find a population that maximizes both yield and profit. Planting too high of a corn population can result in increased barrenness and thus lower yields, but too low of a population also can result in lower yields. Past studies have indicated soybean yields are similar across a wide range of populations, but too low of a population can result in reduced yields and too high of a population can reduce profits. The objective of these trials was to investigate the effect of various planter operations on corn and soybean yield.
Continuities and Discontinuities of Life of Military War Widows in the Post- war Sri Lankan Society

This article is a result of a study on the war widows of fallen security personals attached to tri forces (Navy, Air and Army) of Sri Lanka. The civil conflict which prevailed for three decades in Sri Lanka ended up with many post war issues in different fields such as peace building, addressing the issues of war affected people etc. War widows are considered as one of the issues during and after arm conflicts and many studies have been conducted in order to investigate the issues of the war widows as well as many facilitating and supportive progarmmes have been organized to address these issues. However, the challenges faced by the military war widows in post-war society in Sri Lanka have not being studied adequately. Hence, this study has examined the challenges of military war widows encountering as a result of continuity and discontinuity of their life circle referring to their life course. It has identified three broad challenges faced by military war widows namely the social challenges, economic challenges and psychological challenges. The study which has employed both the secondary and primary data collection approach has concluded with that the gender roles attached to men and women influence in continuing the life as a widow and it sometimes discontinue the women empowerment such as participating into community events and it creates vulnerability of women’s decision making as a widow.
The Relationship Between Gender and Practitioners' Fear in Working with High-Risk Adolescents

This study examined the relationship between the gender of clients and practitioners and practitioners' fears in work with high-risk youth. Two hundred forty eight youth-serving practitioners were surveyed about the frequency of fears about their work. Scores based on these fears were correlated with the percentage of male clients on practitioners' caseloads. Male practitioners were found to have fears related to liability in their work with female youth clients and fears related to physical harm in their work with male youth clients. Female practitioners were found to have fears of damage to their professional reputation from their work with male youth clients.

STATISTICAL CONSULTING: REACTION AND COMMENTS

Publisher Summary This chapter discusses the operation of statistical consulting programs and the philosophy behind these programs. With clients who are graduate students from other departments in the university, one frequently encounters communication difficulties. Sound advice is distorted or ignored, and much valuable time is lost. The students who participate in statistical consulting programs vary widely with respect to ability, background, communication skills, and motivation. Such factors are important considerations in the assignment of students to problems. Students should be given as much responsibility as they can handle. Good communication between the faculty advisor and the students is necessary to monitor the situation. Overloading a student can have disastrous results for everyone concerned. The chapter focuses on attitudes of student. It does not mean that topics or ideas from any branch of statistics should be excluded from a consultant's education. A good consultant needs a wide variety of ideas to attack problems successfully when faced with multiple goals and ambiguity.
Group Theory and the NMR Problem

The NMR (nuclear magnetic resonance) eigenvalue-eigenvector problem presents an interesting problem in group theory. Basically NMR spectroscopy is an angular momentum spectroscopy. As such, one would expect the unitary unimodular groups, SU(n), corresponding to the various nuclei to be of prime importance. However, the nuclei of interest occupy specific positions in molecules and are permuted by the symmetry operations expressing the point symmetry and rapid internal motions of the molecules. Consequently, the finite and discrete groups expressing these symmetries should also come into play. In fact, both of these groups are important. However, the apparent spatial symmetry is frequently higher than that of the point group of the molecule, even when rapid internal motions are included in the spatial symmetry.
National Debates, Local Responses: The Origins of Local Concern About Immigration in the U.K. and the U.S.

Theories of inter-group threat hold that local concentrations of immigrants produce resource competition and thus anti-immigrant attitudes. Variants of these theories are commonly applied to Britain as well as the U.S. Yet the empirical tests have been inconsistent. This comparative paper analyzes geo-coded surveys from both countries to identify when residents’ attitudes are influenced by living near immigrant communities. Using Pew surveys of the U.S. from 2001 and 2006 and the 2005 British Election Study, it illustrates that local contextual effects hinge on national politics. Contextual effects appear primarily when immigration is a nationally salient issue, a finding which explains why past research finds threat in some cases but not others. Seemingly local disputes have national catalysts. The paper also demonstrates how panel data can reduce the selection biases that plague research on local contextual effects.
Unshackling Black Motherhood

When stories about the prosecutions of women for using drugs during pregnancy first appeared in newspapers in 1989, I immediately suspected that most of the defendants were Black women. Charging someone with a crime for giving birth to a baby seemed to fit into the legacy of devaluing Black mothers.' I was so sure of this intuition that I embarked on my first major law review article based on the premise that the prosecutions perpetuated Black women's subordination.2 My hunch turned out to be right: a memorandum prepared by the ACLU Reproductive Freedom Project documented cases brought against pregnant women as of October 1990 and revealed that thirty-two of fifty-two defendants were Black.3 By the middle of 1992, the number of prosecutions had increased to more than 160 in 24 states.4 About 75% were brought against women of color.5
Violence in schizophrenia and bipolar disorder.

BACKGROUND: Although most psychiatric patients are not violent, serious mental illness is associated with increased risk of violent behavior. Most of the evidence available pertains to schizophrenia and bipolar disorder. METHODS: MEDLINE data base was searched for articles published between 1966 and November 2012 using the combination of key words 'schizophrenia' or 'bipolar disorder' with 'aggression' or 'violence'. For the treatment searches, generic names were used in combination with key words 'schizophrenia' or 'bipolar disorder' and 'aggression' No language constraint was applied. Only articles dealing with adults were included. The lists of references were searched manually to find additional articles. RESULTS: There were statistically significant increases of risk of violence in schizophrenia and in bipolar disorder in comparison with general population. The evidence suggests that the risk of violence is greater in bipolar disorder than in schizophrenia. Most of the violence in bipolar disorder occurs during the manic phase. The risk of violence in schizophrenia and bipolar disorder is increased by comorbid substance use disorder. Violence among adults with schizophrenia may follow at least two distinct pathways-one associated with antisocial conduct, and another associated with the acute psychopathology of schizophrenia. Clozapine is the most effective treatment of aggressive behavior in schizophrenia. Emerging evidence suggests that olanzapine may be the second line of treatment. Treatment adherence is of key importance. Non-pharmacological methods of treatment of aggression in schizophrenia and bipolar disorder are increasingly important. Cognitive behavioral approaches appear to be effective in cases where pharmacotherapy alone does not suffice. CONCLUSIONS: Violent behavior of patients with schizophrenia and bipolar disorder is a public health problem. Pharmacological and non-pharmacological approaches should be used to treat not only violent behavior, but also contributing comorbidities such as substance abuse and personality disorders. Treatment adherence is very important for successful management of violent behavior. Language: en
Proteome Profiling of 1 to 5 Spiked Circulating Tumor Cells Isolated from Whole Blood Using Immunodensity Enrichment, Laser Capture Microdissection, Nanodroplet Sample Processing, and Ultrasensitive nanoLC–MS

Proteome profiling of circulating tumor cells (CTCs) can provide crucial insight into disease progression and the role of CTCs in tumor metastasis. We describe an integrated workflow to measure global protein expression in 1-5 spiked CTCs enriched from whole blood by immunodensity gradient centrifugation. Enriched CTCs were purified and collected by laser capture microdissection, prepared using a recently developed nanodroplet-based processing platform (nanoPOTS), and finally analyzed by ultrasensitive nanoLC-MS/MS. The workflow was capable of identifying an average of 164 and 607 protein groups from samples comprising 1 and 5 LNCaP cells, respectively, that were isolated from human whole blood. A panel of prostate cancer-specific proteins were identified and quantified, which was used to differentiate between spiked CTCs and white blood cells.
Impact of parental incarceration on neonatal outcomes and newborn home environments: a case-control study.

Abstract Objectives Parental incarceration (PI) is a prevalent adverse childhood experience (ACE) that has been linked to numerous social, emotional, and health problems in childhood and adulthood. A growing body of research has emphasized the importance of the timing of parent's incarceration on developmental outcomes. Study design The present study uses case–control matching to examine the impact of recent PI on newborn health and home safety outcomes. Methods Neonatal health and newborn sleep and home safety data, including rates of premature birth, low birth weight (LBW), neonatal intensive care unit admittance, breastfeeding initiation, safe sleep, and home environment (e.g. working smoke alarm, proper firearm storage), were collected from 108 women who completed the Virginia Pregnancy Risk Assessment Monitoring survey. Half of these women (n = 54) had experienced the incarceration of themselves or their partner during the previous 12 months. Participants were matched by age, race, income, and the education level with those of 54 women who completed the survey and who had not experienced incarceration in the previous year. Results Controlling for nicotine and alcohol consumption during pregnancy and other stressors, path analyses show that the women who experienced incarceration of themselves or their husband/partner were significantly less likely to deliver an LBW infant and more likely to live in a home with a loaded firearm in the home. No other significant differences emerged between the two matched groups among neonatal health or newborn sleep and home safety outcomes. Conclusions This result is considered from a public health perspective, as PI is an ACE which can be impacted by policy, particularly policies that promote practices that healthcare workers can use in correctional and other environments to encourage healthy pregnancies and home environments for newborns.
Infrasound monitoring in non-traditional environments.

To date, the infrasound community has avoided deployments in noisy urban sites because interests have been in monitoring distant sources with low noise sites. As monitoring interests expand to include low-energy urban sources only detectable close to the source, case studies are needed to demonstrate the challenges and benefits of urban infrasound monitoring. This case study highlights one approach to overcoming urban challenges and identifies a signal's source in a complex acoustic field. One 38 m and one 120 m aperture infrasound arrays were deployed on building rooftops north of downtown Dallas, Texas. Structural signals in the recorded data were identified, and the backazimuth to the source determined with frequency-wavenumber analysis. Fourteen days of data were analyzed to produce 314 coherent continuous-wave packets, with 246 of these detections associated with a narrow range of backazimuth directions. Analyzing the backazimuths from the two arrays identified the Mockingbird Bridge as the probable source which was the verified with seismic measurement on the structure. Techniques described here overcame the constraints imposed by urban environments and provide a basis to monitor infrastructure and its conditions at local distances (0–100 km).To date, the infrasound community has avoided deployments in noisy urban sites because interests have been in monitoring distant sources with low noise sites.

Investigation of Performance Degradation in Enhancement-Mode GaN HEMTs under Accelerated Aging

In this paper, the performance degradation of enhancement-mode (E-mode) GaN HEMFs under accelerated aging is presented in detail. A real-time degradation monitoring tool is essential to prevent costly shutdowns and minimize safety concerns. Specifically, a DC power cycling setup is first designed which operates within the safe operating area (SOA) of the device to mimic the field operation and accelerate the aging process. The E-mode GaN devices are mounted on a custom designed PCB adaptor to accommodate the curve tracer where all the parasitics are carefully controlled to minimize the measurement errors. Using the curve tracer, the parameter shifts are periodically monitored at certain aging cycles. From the experimental results, it is observed that the on-state resistance and the threshold voltage are gradually increasing over the aging cycles, which makes it potential failure precursors. Meanwhile, a variation in the transfer characteristics is observed, and the transconductance decreases as the device is aged. Finally, a detailed theoretical analysis is provided to explain this parameter shift in experiments.

Evaluation of the automated aptima HIV-1 quant Dx assay for both qualitative and quantitative testing in pediatric patients

Abstract Background There are currently no FDA-cleared assays with a dual-claim for both diagnosis and monitoring of HIV-1. The Aptima HIV-1 Quant Dx Assay on the Panther platform (Panther) is the first commercially available test that is CE-marked for both HIV-1 diagnosis and monitoring, but only FDA-cleared for HIV-1 monitoring. Objective To evaluate the Panther assay for use as a qualitative and quantitative HIV-1 assay in a pediatric population, including patients younger than 24 months old, and review its effect on laboratory efficiency and hands-on-time following its implementation. Study Design 100 patient specimens previously tested on the Abbott m2000 RealTime HIV-1 assay (RealTime) and 185 patient specimens previously tested on the Aptima HIV-1 RNA Qualitative Assay (RNA Qual) were tested on the Panther. Verification panels were used to establish precision and linearity. In addition, 268 samples from 134 patients under 24 months of age were also evaluated on the Panther. Results Overall agreement between the Panther and RealTime assays was 83 %. The mean difference between the two methods was 0.10 Log copies/mL. All Panther measurements were linear across the dynamic range (R2 = 0.999). The Panther and RNA Qual assays showed 100 % agreement. Implementation of the assay opened 600 sq. ft. of space, saved 0.4 FTE and reduced hands-on-time by 70 %. Conclusions The Panther assay is an excellent option for HIV-1 qualitative detection and quantitative testing in pediatric patients, including those under 24 months of age. HIV testing on one platform has opened up space in the clinical laboratory and reduced hands on testing time.
Compositional dependence of crystallization temperatures and phase evolution in hafnia-zirconia (HfxZr1−x)O2 thin films

Polymorphic (HfxZr1−x)O2 (HZO) thin films exhibit ferroelectric, dielectric, and antiferroelectric properties across a wide compositional range due to the existence of orthorhombic, monoclinic, and tetragonal phases. To better understand the phase stability across the HfO2–ZrO2 compositional range, we investigate the structural evolution of HZO thin films in situ via high-temperature x-ray diffraction (HTXRD) for five different compositions [ZrO2, (Hf0.23Zr0.77)O2, (Hf0.43Zr0.57)O2, (Hf0.67Zr0.33)O2, and HfO2]. The real-time monitoring of HZO crystallization reveals a competing driving force between the tetragonal and monoclinic phase stabilities for HfO2-rich vs ZrO2-rich compositions. Additionally, we confirm an XRD peak shift toward lower 2θ with increasing temperature in ZrO2, (Hf0.23Zr0.77)O2, and (Hf0.43Zr0.57)O2 films, which we ascribe to the appearance of a metastable orthorhombic phase during heating. A monotonic trend for the onset crystallization temperature is reported for five compositions of HZO and reveals an increase in onset crystallization temperature for HfO2-rich compositions. Relative intensity fraction calculations suggest a higher fraction of monoclinic phase with increasing annealing temperature for (Hf0.67Zr0.33)O2. This study of phase stability and onset crystallization temperatures offers insight for managing the thermal budget for HZO thin films, especially for temperature-constrained processing.
In-situ strain measurement of ballistic fabrics during impact using fiber Bragg gratings

Abstract In previous experiments, the authors demonstrated that strain values collected from fiber Bragg gratings (FBG) integrated into a single layer of Kevlar fabric, placed between a soft armor test specimen and backing material, could be related to the time dependent back-face deformation (BFD) of the armor sample. In this paper, we investigate the specific fabric deformation and failure mechanisms that cause observed events in the FBG measured strain behavior and the FBG spectral profile throughout the impact event. For these experiments, the standard clay backing material was replaced with a 20% clear ballistic gel to provide visual access to the back-face. The test specimen was impacted by an 8.24 g steel ball bearing travelling at 248.8 m/s, during which strain was calculated from the measured full spectrum response of the FBG using a high-speed optical interrogation system. The strain response was compared to the BFD of the Kevlar sample. The BFD was measured through the clear ballistic gel using two high speed cameras recording at 100,000 fps. The results from these tests can be used for future testing using a non-transparent backing material to obtain a detailed strain–time history, back-face deformation history and an understanding of the time sequence of physical energy dissipation mechanisms in the fabric.

Robotics assisted smart-touch pipeline inspection

A timely inspection of pipelines is of great importance to prevent oil and gas from leaking. This paper develops a novel robotic system that can automatically grab a flange of pipelines and perform bolt looseness inspection autonomously. The robotic system consists of a 4-DOF robotic arm with a stereo camera system on a mobile platform and a pair of piezoceramic transducers (PZTs) mounted on two fingers of the robotic arm. The PZTs act as a smart touch sensor for bolt looseness inspection when the fingers grab a flange. An onboard visual tracking algorithm is developed to provide the 3D position of the flange. The flange is first recognized and then localized in a 2D image by YOLO region-based convolutional neural networks. The 2D position in the image is then transferred to the 3D position through a set of calibrated stereo camera parameters. The robotic arm receives proportional gain control signals based on the distance between the finger center and the flange. In the experiment, we install four cameras, apply a feature-based location method, and calculate the average value of history positions to reduce the detection error. When the robotic arm grabs the flange, a stress wave signal is generated by one of the PZTs mounted on the fingers, and the signal received from the other PZT indicates if the flange is tightly bolted or not. Experimental results have validated this autonomous robotic inspection approach.
Opportunities and Risks for Game-Inspired Design of Adaptive Instructional Systems

The application of game elements within learning environments takes many forms, including serious games, interactive virtual environments, and the application of game mechanics within non-gaming contexts. Given the breadth of strategies for implementation game-elements into instructional systems, it is important to recognize that each strategy carries its own potential benefits and risks. The purpose of the current paper is to review the relevant interdisciplinary literature regarding the application of games and game-elements to learning contexts, and identify the factors to consider when developing a game-inspired instructional system. Secondly, the current discussion considers the special case of game technology and game design elements in intelligent tutoring, and identifies future research opportunities to meaningfully integrate such features in adaptive tutoring systems.
An Examination of Commercial Medicinal Plant Harvests, Mount Hood National Forest, Oregon

An abstract of the thesis of Shannon Michelle Campbell for the Master of Science in Geography presented June 6, 2000. Title: An Examination of Commercial Medicinal Plant Harvests, Mount Hood National Forest, Oregon. During the past fifteen years, non-timber or special for~st products have become an important economic resource in the Pacific Northwest. These products are primarily derived from understory species and contribute approximately $200 million to the regional economy. Medicinal plants are a little researched component ofthe non-timber forest product industry that relies on cultivated and wildcrafted (or wild-collected) medicinal plant species. This study examines the commercial extraction of wildcrafted medicinal plants from Mount Hood National Forest. Specifically, this study documents the medicinal plant species extracted from Mount Hood National Forest, their annual yield amounts, harvesting methods, and the changes in cover of target species after harvest. This research uses survey data obtained from employees of two herbal companies and representatives of the U.S. Forest Service to describe medicinal plant extraction and administration as it pertains to the commercial extraction of plant species from Mount Hood National Forest. Field data were also used to examine changes in plant cover for four medicinal plant species (kinnikinnick, yarrow, Oregon grape and valerian) following harvest. Field results indicate that medicinal plant cover decreased significantly in all but one harvested sampling unit. Permanent unit markers were established at all the study sites to provide opportunities for long-term monitoring of target species responses to harvest. Eleven medicinal plant species are commonly collected for commercial purposes from Mount Hood National Forest. The general lack of regulation and enforcement of commercial medicinal plant extraction coupled with an increasing demand for wildcrafted medicinal plants warrant a need for increased collaboration between regulatory agencies, herbal companies, and the general public. Additional management and research recommendations regarding the ecological impacts of medicinal plant removal are also presented.
