Comparison of Cubic-Plus-Association and Perturbed-Chain Statistical Associating Fluid Theory Methods for Modeling Asphaltene Phase Behavior and Pressure–Volume–Temperature Properties

The tendency of asphaltene, the heaviest and most polarizable component of crude oil, to deposit and block wellbores and pipelines can potentially lead to production loss and significant cost of remediation. Asphaltenes constitute a particular interest in oil production because of the lack of understanding of their molecular structure and the mechanisms by which they precipitate and deposit. Because prevention is far less expensive than removal, a better understanding of asphaltene precipitation and deposition phenomena is of great importance for the oil industry. Precipitation, which is a necessary but not sufficient condition for deposition, requires accurate modeling of asphaltene phase behavior with respect to variations in the temperature, pressure, and composition. Over the past decade, cubic-plus-association (CPA) and perturbed-chain statistical associating fluid theory (PC-SAFT) equations of state (EOSs) have been proposed for modeling complex systems, such as asphaltenic crude oils. In this work,...

Alterations in tretinoin pharmacokinetics following administration of liposomal all-trans retinoic acid

We administered liposome-encapsulated all-trans retinoic acid (L-ATRA) to 48 patients with refractory hematologic malignancies using an every-other-day schedule for 28 days and doses of 15 to 175 mg/m2. In 19 patients, pharmacology studies were conducted after the first (day 1) and seventh (day 15) doses. In contrast to the decline in tretinoin concentration seen within 3 to 4 days of administration of daily oral ATRA, there were no differences between the area under the curve (AUC) of tretinoin concentration versus time on day 1 and day 15 (P = .98, Wilcoxon signed-rank test). Peak day 1 concentrations after 15 mg/m2 were higher than those reported after 45 mg/m2 oral ATRA. Six patients with relapsed acute promyelocytic leukemia (APL) were treated. Three, each in first relapse and at least year from the last exposure to oral ATRA, achieved a complete response (CR). Disease recurred in two (one at 3 months despite maintenance L-ATRA and similarity in tretinoin AUC on days 1 and 85, and the other at 5 months, 2 months after discontinuation of L-ATRA) and the third was transplanted 1 month into CR. The three nonresponders were in at least a second relapse and failed to respond to oral ATRA before or immediately after receiving L-ATRA. Severe toxicity developed in three of eight patients treated at 175 mg/m2 (joint pains in two, skin in one). The maximum tolerated dose (MTD) was determined to be 140 mg/m2, at which dose grade 2 toxicity (primarily headache and skin) occurred in eight of eight patients, but grade 3 to 4 toxicity in none. Compared with oral ATRA, L-ATRA apparently results in greater exposure to tretinoin and for a longer time.
Interpretation of cutaneous biopsy specimens: choice of pathologist by primary care practitioners.

Background. Primary care providers (PCPs) have limited training in recognizing common skin disorders, and additional emphasis may be placed on laboratory evaluation, including skin biopsies. Methods. Primary care providers in Miami, Fla, were surveyed regarding skin biopsy and excision practices and histologic interpretation. They then participated in an examination, using 20 high-quality color photographs of common dermatologic disorders. Results. Of the 80 PCPs who participated, 42% currently do skin biopsies and consult general pathologists for interpretation. Another 20% of PCPs intend to do biopsies within the next 5 years. Only 33% prefer to have a dermatopathologist interpret histopathology. We found no correlation between PCPs' scores on diagnostic testing and whether they do skin biopsies. Conclusion. Nearly all PCPs doing skin biopsies in our study sample use general pathologists to interpret histopathology, The limited training in clinical dermatology of both PCPs and general pathologists may result in compromised clinical-pathologic correlation.
Reaction of ethyl diazoacetate with Co3(CO)9(μ3-CCl): Isolation and X-ray structures of Co3(CO)9(μ3-CCO2Et), Co3(CO)9(μ3-CCH2CO2Et), and [Co3(CO)9(μ3-CCHCO2Et)]2

The reaction between the tricobalt cluster Co3(CO)9(μ3-CCl) (1) and AlCl3, followed by treatment with ethyl diazoacetate, N2CHCO2Et, affords a complex mixture of products in low yields. Column chromatography has allowed the isolation of the four cluster compounds Co3(CO)9(μ3-CH) (2), Co3(CO)9(μ3-CCO2Et) (3), Co3(CO)9(μ3-CCH2CO2Et) (4), and [Co3(CO)9(μ3-CCHCO2Et)]2 (5). Clusters 4 and 5 are new and have been fully characterized in solution by IR and 1H NMR spectroscopy. The molecular structures of clusters 3–5 have also been determined by single-crystal X-ray diffraction analysis. Co3(CO)9(μ3-CCO2Et) crystallizes in the triclinic space group P $$\bar 1$$ , a = 8.8393(5), b = 14.727(1), c = 15.272(1) A, α = 93.361(6), β = 105.509(5)°, γ = 100.336(6)°, V = 1872.6(2) A3, Z = 4, and d calc = 1.823 g/cm3. Co3(CO)9(μ3-CCH2CO2Et) crystallizes in the monoclinic space group P21/n, a = 9.3806(7), b = 9.2617(8), c = 22.455(2) A, β = 94.483(7)°, V = 1944.9(3) A3, Z = 4, and d calc = 1.803 g/cm3. [Co3(CO)9(μ3-CCHCO2Et)]2 crystallizes in the monoclinic space group C2/c, a = 21.585(2), b = 8.7977(7), c = 20.784(1) A, β = 104.807(6)°, V = 3815.8(5) A3, Z = 4, and d calc = 1.835 g/cm3. Plausible pathways leading to the formation of clusters 2, 4, and 5 are discussed.
A survey of skin-to-skin contact with perinatal nurses

Abstract Objective This study explored perinatal nurses' knowledge, attitudes and practices of SSC, to identify knowledge-practice gaps. Study design A descriptive cross-sectional survey design was completed by 101 perinatal nurses. Descriptive statistics and ordered logistical regression were used to describe and compare nurses' responses. Results The participants strongly agreed that it is nurses' responsibility to advocate for SSC. Significant differences ( p p Conclusions Perinatal nurses strongly believe in SSC practices, yet additional training regarding SSC implementation is needed. Education levels, primary practice settings and years of practice appear to influence nurses' implementation of SSC.
An Open Trial Targeting Food Cue Reactivity and Satiety Sensitivity in Overweight and Obese Binge Eaters

Data suggests that individuals who binge eat are more responsive to food cues in the environment and less sensitive to satiety cues. The aim of this open trial was to evaluate the feasibility, acceptability, and initial effectiveness of a novel treatment grounded in Schachter's externality theory targeting food cue reactivity and satiety responsiveness with obese adults who binge eat. Treatment was provided in groups, and utilized appetite monitoring, cue-exposure treatment, in vivo exercises, self-monitoring, and coping skills. Twenty-eight overweight and obese adults who binge eat (82% female; mean age = 47.5 years [SD = 12.8]; BMI = 38.9 [SD = 10.3]; 79% White non-Hispanic) participated in a 4-month group-based treatment program. Assessments were conducted at baseline, posttreatment, and 3-month follow-up time points. Results indicated that this treatment was well accepted and had high retention at posttreatment. Initial effectiveness showed significant decreases in BMI, and improvements in loss of control and overeating episodes, food responsiveness, and power of food. The majority of results were maintained at the 3-month follow-up time point. This open trial provides preliminary evidence for the feasibility, acceptability, and initial effectiveness of this treatment on both eating disorder symptoms and weight in obese adults who binge eat. Because these data are preliminary, further treatment development and randomized controlled studies are needed.
Tactical geospatial intelligence from full motion video

The current proliferation of Unmanned Aircraft Systems provides an increasing amount of full-motion video (FMV) that, among other things, encodes geospatial intelligence. But the FMV is rarely converted into useful products, thus the intel potential is wasted. We have developed four concept demonstrations of methods to convert FMV into more immediately useful products, including: more accurate coordinates for objects of interest; timely, geo-registered, orthorectified imagery; conversion of mouse-clicks to object coordinates; and first-person-perspective visualization of graphical control measures. We believe these concepts can convey valuable geospatial intelligence to the tactical user.
Asymptotic-Preserving Schemes for Multiscale Hyperbolic and Kinetic Equations

Abstract Hyperbolic and kinetic equations often possess small spatial and temporal scales that lead to various asymptotic limits. Numerical approximation of these equations is challenging due to the presence of stiff source, collision, forcing terms, or when different scales coexist. Asymptotic-preserving (AP) schemes are numerical methods that are efficient in these asymptotic regimes. They are designed to capture the asymptotic limit at the discrete level without resolving small scales. This chapter aims to review the current status of AP schemes for a large class of hyperbolic and kinetic equations. We will first use simple models to illustrate the basic design principles, and then describe several generic AP strategies for handling general equations. Various aspects of the AP schemes for different asymptotic regimes, including some recent development, will be discussed as well.
Regularized deconvolution method for turbulent combustion modeling

Abstract The modeling of filtered chemical source terms in large-eddy simulation (LES) of turbulent reacting flows remains a challenge. Deconvolution methods are an attractive technique for representing these unclosed terms. With this technique, filtered scalars are reconstructed through deconvolution. The chemical source terms that are computed directly from the deconvolved scalars are filtered explicitly to represent the turbulence-chemistry interaction. However, the approximate deconvolution method (ADM), frequently employed for non-reacting flows, exhibits shortcomings for reacting scalars. This is because ADM does not ensure essential conservation and boundedness conditions. To address this issue, we propose a regularized deconvolution method (RDM) based on an optimization procedure. We conduct a priori and a posteriori analyses to examine RDM as a closure in LES. These investigations are performed in the context of explicit filtering. By showing that RDM is accurate and stable with respect to both the filter width and time, we conclude that the new deconvolution method shows promise in application to combustion LES.
Effect of reduced processing on recovery of foodborne pathogens from hot-boned broiler meat and skin.

Recovery of pathogens from breast meat, thigh meat and skin from scalded, defeathered but uneviscerated broiler carcasses with and without spray washing was compared to recovery from breast meat, thigh meat and skin from fully processed, chilled carcasses (controls). The incidence of coagulase-positive staphylococci was not significantly different on meat and skin from both uneviscerated carcasses with and without a spray washing compared to meat and skin from fully processed carcasses. The incidence of Clostridium perfringens was not significantly different on skin, breast and thigh meat for any of the sampling sources except that incidence on meat from control breasts was lower than on breast meat from uneviscerated carcasses without spray-washing; and incidence on meat from control thighs was lower than on meat from spray-washed, uneviscerated carcasses. Salmonella incidence was higher on both breast and thigh meat from fully processed control carcasses than from uneviscerated unwashed carcasses. When uneviscerated carcasses were spray-washed after defeathering, the incidence of Salmonella was not significantly different on breast meat, and significantly lower on thigh meat than on these meats from fully processed control carcasses. Skin from fully processed control carcasses had a higher incidence of Salmonella than did skin from uneviscerated, unwashed carcasses, but not skin from uneviscerated, spray-washed carcasses. Reducing the number of stages of processing significantly reduced the incidence of Salmonella but not of coagulase-positive staphylococci or Clostridium perfringens .

How the environment is positioned in the Next Generation Science Standards: a critical discourse analysis

AbstractThe purpose of this paper is to describe how the environment and environmental issues are conceptualized and positioned in the Next Generation Science Standards (NGSS) to examine underlying assumptions about the environment. The NGSS are a recent set of science standards in the USA, organized and led by Achieve Inc., that propose science education goals based on the National Research Council report, A Framework for K-12 Science Education. Drawing from critical discourse analysis, we present a detailed textual analysis of the NGSS to identify the positioning of the environment with respect to humans and human activity. This analysis shows patterns in the ways that the environment is conceptualized and inscribed in the standards as an entity separate from people through both exclusion and ambiguity. We also discuss findings about how agency is more often ascribed to actions or activities rather than people and when solutions to environmental issues are included, the focus is on technoscientific solu...
Right Hemisphere Contributions to Understanding Lexical Connotation and Metaphor

Publisher Summary The denotation of a word or concept is typically considered as its literal or dictionary meaning. The connotation, usually is more broadly construed, often in the emotive aspects. The contrast between denotation and connotation is expressed largely in terms of the degree of generality. The aphasic patient groups perform quite differently. The anterior lesioned group's average results represent denotative meaning distinctions less clearly than connotative and less constrained associations. The hierarchical clustering solution for the anterior-lesioned group shows a relatively clean discrimination between human and nonhuman terms except that the concept dog is not seen as belonging particularly well to either the human or the nonhuman cluster. In contrast, on receipt of a word, the right hemisphere characteristically generates diffuse activation related to the word's semantic content, including even weakly associated connotative components. This diffuse activation of both closely and distantly associated concepts is one central claim of Beeman's model. Invoking an underspecified neurological framework for any cognitive task often results in a dangerously powerful account.
Anti-IgE and Anti-IL5 Biologic Therapy in the Treatment of Nasal Polyposis: A Systematic Review and Meta-analysis.

Objective:To determine the role of biologic therapy on sinonasal symptoms and objective outcomes in chronic rhinosinusitis with nasal polyposis (CRSwNP).Methods:PubMed, OVID MEDLINE, and Cochrane Central were reviewed from 2000 to 2015. Inclusion criteria included English-language studies containing original data on biologic therapy in CRSwNP patients with reported outcome measures. Two investigators independently reviewed all manuscripts and performed quality assessment and quantitative meta-analysis using validated tools.Results:Of 495 abstracts identified, 7 studies fulfilled eligibility: 4 randomized control trials (RCT), 1 case-control, and 2 case series. Outcome measures included nasal polyp score (NPS,6), computer tomography score (5), and symptom scores (5). Meta-analysis was performed on 5 studies: Anti-IL5 therapy (mepolizumab/reslizumab) and anti-IgE therapy (omalizumab) demonstrated a standard mean difference of NPS improvement of −0.66 (95% CI, −1.24 to −0.08) and −0.75 (95% CI, −1.93 to 0.44...
Social Security is NOT a Substitute for Annuities

Common wisdom suggests that a fully-funded actuarially fair social security system must increase welfare when households face longevity risk and annuity markets are missing. This wisdom is based on the observation that social security pays benefits as life annuities and therefore appears to complete the market. However, we argue that common wisdom is based on a benefit-only analysis that ignores a fundamental cost— social security crowds out the bequests that households leave (and receive) in general equilibrium. We conduct a general equilibrium cost-benefit analysis of the insurance role of social security, and we show that under very general and empirically relevant conditions, this decline in bequest income osets any possible gains from access to a public annuity pool. We abstract from distortions to national income and factor prices to show that the equilibrium bequest channel is all that is needed to reach this conclusion.
Endogenous factors related to susceptibility to damage from noise

There are few endogenous factors related to susceptibility to damage from noise other than those that affect the transmission of sound to the cochlea--i.e., characteristics of the outer and middle ears--and a few substances that affect the oxygen reaching the cochlea, including oxygen intake itself. Susceptibility has not been shown to be dependent on gender, skin color, any known diseases, mental attitude toward the noise, exposure history, preexposure hearing loss, nor-surprisingly, in view of the importance of carbon monoxide--history of smoking.
The effect of health insurance on sexual health: Evidence from the Affordable Care Act's dependent coverage mandate.

Abstract This study estimates changes in sexually transmitted disease rates for young adults in the United States following the Affordable Care Act's dependent coverage mandate; a provision that allows dependents to remain covered under their parents' health insurance plans until the age of 26. This study is the first to analyze changes in reported chlamydia and gonorrhea rates resulting from the dependent coverage mandate. Utilizing a difference-in-differences framework coupled with administrative data from the Centers for Disease Control and Prevention, I find that reported chlamydia rates increased for males and females ages 20–24 relative to comparison groups of males and females ages 15–19 and 25–29 following the mandate. I also find evidence of an increase in gonorrhea rates for females in this age group. I find no evidence that the mandate induced ex ante moral hazard.
Risk factors for Mycoplasma genitalium endometritis and incident infection: a secondary data analysis of the T cell Response Against Chlamydia (TRAC) Study

Objective Assess risk factors for incident and endometrial Mycoplasma genitalium infection and determine if M. genitalium is associated with histological endometritis, an indicator of pelvic inflammatory disease. Methods This study was a secondary data analysis within the T cell Response Against Chlamydia (TRAC) Study, a prospective evaluation of 246 women with or at risk for Chlamydia trachomatis from urban outpatient clinics, who were followed quarterly for 12 months. Risk factors for incident M. genitalium infection were determined by Cox regression. Relative risks were estimated by Poisson regression with robust error measurements for models examining the association between M. genitalium and endometritis (histological evidence of plasma cells in endometrial stroma and neutrophils in the endometrial epithelium) and for models examining risk factors for detection of endometrial M. genitalium infection. Results M. genitalium prevalence was 16.7%, incidence was 25.3 per 100 person-years and 23% had repeated positive tests. Black race (non-black HR adj 0.4, 95% CI 0.2 to 0.9), less education (HR adj 2.4, 95% CI 1.2 to 5.1) and a new sexual partner (HR adj 3.1, 95% CI 1.7 to 5.4) were associated with incident M. genitalium. M. genitalium was associated with endometritis (RR adj 2.0, 95% CI 1.1 to 3.7). Trichomonas vaginalis (RR adj 2.0, 95% CI 1.2 to 3.4) and endometrial C. trachomatis (RR adj 1.7, 95% CI 1.1 to 2.8) were associated with endometrial M. genitalium . Conclusions M. genitalium is prevalent in women at high risk for C. trachomatis , persists over multiple follow-up visits and is associated with histological endometritis. Studies are needed to determine if screening for M. genitalium will improve reproductive outcomes.

Fatty Acids That Inhibit Cancer: Conjugated Dienoic Derivatives of Linoleic Acid

Evidence for the anticarcinogenic activity of the conjugated dienoic derivatives of linoleic acid (CLA) is reviewed. CLA is present in grilled beef, cheese, and related foods. It is also generated endogenously via carbon centered free radical oxidation of linoleic acid. New findings indicate that CLA is a potent antioxidant. CLA may provide a previously unrecognized in situ defense mechanism against membrane attack by oxygen radicals.

RSA: Implementation and Security

The need for secure communication methods between remote parties has existed for as long as remote parties have wished to communicate. The rise of the digital computer in the beginning of the twentieth century brought with it a new paradigm in secure communications – computer-based encryption algorithms. Encryption is a process by which some private set of data, often called a plaintext, is deterministically converted in a seemingly random set of data called a ciphertext. This ciphertext is then later converted deterministically back into the plaintext through a process called decryption. Encryption and decryption can be thought of as the “locking” and “unlocking” of the plaintext. Imagine a plaintext as a piece of paper with sensitive information written on it. By placing this piece of paper in an unbreakable box with an unpickable lock, we have “encrypted” this data in such a way that only the person or persons with the right key can “decrypt” the data. There are two main ways in which two parties A and B could transmit data with this ideal box/lock combination. First, party A could give party B a copy of their unpickable lock’s key during some secure, personal meeting between the two parties. At a later date, party A could “encrypt” the data using their box and lock and then send the box to party B, who, having obtained the key to this lock at the prior meeting would be able to “decrypt” the data upon receiving it. In this example, both parties could continue sending data back and forth to each other while using the same key. This type of encryption is called “symmetric” encryption – both parties use the same key.
Representations and Cohomology

This is the first of two volumes which will provide an introduction to modern developments in the representation theory of finite groups and associative algebras. The subject is viewed from the perspective of homological algebra and the theory of representations of finite dimensional algebras; the author emphasises modular representations and the homological algebra associated with their categories. This volume is self-contained and independent of its successor, being primarily concerned with the exposition of the necessary background material. The heart of the book is a lengthy introduction to the (Auslander–Reiten) representation theory of finite dimensional algebras, in which the techniques of quivers with relations and almost split sequences are discussed in detail.Much of the material presented here has never appeared in book form. Consequently students and research workers studying group theory and indeed algebra in general will be grateful to Dr Benson for supplying an exposition of a good deal of the essential results of modern representation theory.
What socio-demographic characteristics predict knowledge of biofuels

Abstract The assessment of people's knowledge on biofuels is sporadic mainly due to a lack of an objective knowledge scale. We conducted large-scale mail surveys to fill the gap and assess people's knowledge of biofuels and the social-demographic characteristics related to this. We sent out mail surveys to 4733 valid addresses and received 1376 completed surveys. Biofuels knowledge was assessed with five items related to energy content, production capacity, and potential benefits and harm of biofuels, assigning + 1 or + 2 points for correct, and − 1 or − 2 points for incorrect answers depending upon respondents’ certainty about the answer, and 0 point for ‘I don’t know’ responses. We constructed a summary index by summing the points scored on the five items. The mean score for the biofuels knowledge index was 2.25 ± 3.33 on the scale of − 10 to + 10 points. The multiple regression results showed that socio-demographic attributes are significant predictors of biofuels knowledge: men scored 1.65 points higher than women; for one level increment in education, respondents scored 0.26 points higher; and Democrats scored 1.34 points lower than others. Possible reasons for these results and their implications for policy and management to make cellulosic biofuels successful are discussed.
Race modifies default mode network connectivity in Alzheimer’s disease

Abstract Objective To determine if resting state functional MRI biomarkers of Alzheimer’s disease (AD) differ between older African Americans and Caucasians. Methods We analyzed MRI profiles from 78 individuals (31 African Americans, 47 Caucasians) with normal cognition (n=36) or mild cognitive impairment/mild AD dementia (MCI/AD, n=42). We compared AD-associated intra-network functional connectivity of the default mode network (DMN) according to race, and correlated domain-specific cognitive functions with functional connectivity which differed between the racial groups. Results We identified key differences in DMN functional connectivity associated with AD between the races. Whereas MCI/AD was associated with decreased functional connectivity within the midline core DMN subsystem in older Caucasians, MCI/AD was instead associated with increased functional connectivity within the same subsystem of older African Americans. This is despite decreased functional connectivity in the medial temporal lobe DMN subsystem in both races. Memory function was also positively associated with connectivity between the precuneus and the posterior cingulate/inferior parietal lobule within the midline core subsystem, in keeping with a less amnestic-profile in older African Americans with MCI/AD. Conclusions These findings provide structural support that race modifies the AD phenotypes downstream from cerebral amyloid deposition, and suggests a rsf-MRI correlate of African American’s less amnestic neuropsychological profile in MCI/AD.
Indirect Estimation of Race/Ethnicity for Survey Respondents Who Do Not Report Race/Ethnicity.

Existence and nonexistence to exterior Dirichlet problem for Monge–Ampère equation

We consider the exterior Dirichlet problem for Monge–Ampere equation with prescribed asymptotic behavior. Based on earlier work by Caffarelli and the first named author, we complete the characterization of the existence and nonexistence of solutions in terms of their asymptotic behaviors.
The Use of Deep Convolutional Neural Networks in Biomedical Imaging: A Review

Introduction: This review sought to present fundamental principles of deep convolutional neural networks (DCNNs) and provides an overview of its applications in medicine and dentistry. Materials and Methods: Scientific databases including PubMed, Science Direct, Web of Science, JSTOR, and Google Scholar were used to search for relevant literature on DCNN and its applications in the medical and dental fields from 2010 to September 2018. Two independent reviewers rated the articles based on the exclusion and inclusion criteria, and the remaining articles were reviewed. Results: The comprehensive literature search yielded 110,750 citations. After applying the exclusion and inclusion criteria, 340 articles remained that pertained to the use of DCNN in medicine and dentistry. Further exclusion based on nonbiomedical applications yielded a total of 26 articles for review. Conclusion: Advances in the development of neural network systems have permeated into the medical and dental fields, particularly in imaging and diagnostic testing. Researchers are attempting to use deep learning as an aid to assess medical images in clinical applications and its optimization will provide powerful tools to the next generation. However, the authors caution that these tools serve as supplements to improve diagnosis and not replace the medical professional.
Robotic assisted carotid artery stenting for the treatment of symptomatic carotid disease: technical feasibility and preliminary results.

Background and purpose Robotic-assisted endovascular interventions have been increasingly performed in the coronary and peripheral vascular beds. We aim to describe the feasibility and initial safety of a robotic-assisted platform for treating carotid artery disease. Methods Single-center technical report of the first four consecutive cases of carotid artery stenting for the treatment of severe symptomatic carotid stenosis utilizing the CorPath GRX Robotic System (Corindus Inc, Waltham, MA). Results Four patients (one in early 60s and three in early 70s; NASCET degree of stenosis: 88%, 77%, 83% and 82%) with ipsilateral strokes on presentation were treated. All steps of the procedure (including delivery/removal of micro-guidewire, emboli-protection system and angioplasty balloon) could be successfully performed robotically with the exception of navigation/deployment of the stents due to incompatibility with the current robotic platform. Technical success was achieved in all patients resulting in resolution of the stenosis without any complications. Conclusions Robotic-assisted carotid artery stenting is technically feasible. Future studies are warranted to properly establish safety and benefits.

Another Piece of the Puzzle: The Emergence of the Present Perfect

This article examines the emergence of the present perfect in the interlanguage of 16 instructed adult learners of English as a second language. It is part of a longitudinal study of the expression of temporality in interlanguage; it focuses on the learners' form-meaning associations by investigating their use of the present perfect in written and oral texts. The article first describes the order of emergence of the present perfect with respect to other tense/aspect forms and then the potential influence of instruction by comparing production to instructional logs. Examination of the linguistic contexts in which the present perfect appears shows that adding a new inflection in the tense/aspect system requires not only establishing new form-meaning associations but also revising existing ones.

Medical Assistant Protocol Improves Disparities in Depression Screening Rates.

Introduction Depression is a prevalent condition for which screening rates remain low and disparities in screening exist. This study examines the impacts of a medical assistant screening protocol on the rates of depression screening, overall and by sociodemographic groups, in a primary care setting. Methods Between September 2016 and August 2018, a quasi-experimental study of adult primary care visits was conducted at an urban academic clinic to ascertain the change in the rates of completion of the Patient Health Questionnaire-2 after the implementation of a medical assistant protocol (intervention) versus that of physician-only screening (control arm). Analyses were conducted between April 2019 and April 2020 and used interrupted time-series models with generalized estimating equations. Results A total of 45,157 visits by 21,377 unique patients were included. Overall, screening increased from 18% (physician-only screening) to 57% (medical assistant protocol) (p Conclusions Implementation of a medical assistant protocol in a primary care setting may significantly increase depression screening rates while mitigating or removing sociodemographic disparities.
Disrupting Notions of 'Choice': Missteps in Ontario’s COVID-19 Back-to-School Plan

When schools shut down in Ontario during the COVID-19 Pandemic, many voices chimed in to discuss where children should be. However, children’s voices were largely missing from these discussions by virtue of being excluded by those in charge. Under the United Nations Convention on the Rights of the Child (1989), children are granted the right to express themselves, have that expression be taken seriously, and to be given information on matters that concern them. By conducting an analysis of the Ontario Government’s Back-to-School Plan and announcements, I argue that the developmental and economic framing of the decision to return to school denied children their expression rights guaranteed under the UN-CRC. The Ontario Government missed a vital opportunity to value children as full human beings with integral experiences. I conclude by arguing that it is imperative that the Government commits to using a rights-respecting approach to all policy and programming with potential to impact children or childhood.
Gated photocathode design for the P510 electron tube used in the National Ignition Facility (NIF) optical streak cameras

ABSTRACT The optical streak cameras currently used at the National I gnition Facility (NIF) implement the P510 electron tube from Photonis 1 . The existing high voltage electronics provide DC bias voltages to the cathode, slot, and focusing electrodes. The sweep deflection plates are driven by a ramp voltage. This configuration has been very successful for the majority of measurements required at NIF. New experiments require that the photocathode be gated or blanked to reduce the effects of undesirable scattered light competing with low light level experimental data. The required ~2500V gate voltage is applied between the photocathode and the slot electrode in response to an external trigger to allow the electrons to flow. Otherwise the slot electrode is held approximately 100 Volts more negative than the potential of the photocathode, preventing electron flow. This article reviews the implementa tion and performance of the gating circuit that applies an electronic gate to the photocathode with a nominal 50ns rise and fall time, and a pulse width between 50ns and 2000ns.

Maximum Entropy States and Coherent Structures in Magnetohydrodynamics

We review a recently developed model of coherent structures in two- dimensional magnetohydrodynamic turbulence. This model is based upon a constrained maximum entropy principle: Most probable states are determined as maximizers of entropy subject to constraints imposed by the conservation of energy, cross-helicity, and flux under the evolution of an ideal two-dimensional mag- netofluid. Predictions of the model are compared with results of high-resolution numerical simulations of magnetofluid turbulence.
Classification of Listeria monocytogenes persistence in retail delicatessen environments using expert elicitation and machine learning.

Increasing evidence suggests that persistence of Listeria monocytogenes in food processing plants has been the underlying cause of a number of human listeriosis outbreaks. This study extracts criteria used by food safety experts in determining bacterial persistence in the environment, using retail delicatessen operations as a model. Using the Delphi method, we conducted an expert elicitation with 10 food safety experts from academia, industry, and government to classify L. monocytogenes persistence based on environmental sampling results collected over six months for 30 retail delicatessen stores. The results were modeled using variations of random forest, support vector machine, logistic regression, and linear regression; variable importance values of random forest and support vector machine models were consolidated to rank important variables in the experts’ classifications. The duration of subtype isolation ranked most important across all expert categories. Sampling site category also ranked high in importance and validation errors doubled when this covariate was removed. Support vector machine and random forest models successfully classified the data with average validation errors of 3.1% and 2.2% (n = 144), respectively. Our findings indicate that (i) the frequency of isolations over time and sampling site information are critical factors for experts determining subtype persistence, (ii) food safety experts from different sectors may not use the same criteria in determining persistence, and (iii) machine learning models have potential for future use in environmental surveillance and risk management programs. Future work is necessary to validate the accuracy of expert and machine classification against biological measurement of L. monocytogenes persistence.
A Multiply Imaged Luminous Infrared Galaxy Behind the Bullet Cluster (1E0657-56)

We present evidence for a Spitzer-selected luminous infrared galaxy (LIRG) behind the Bullet Cluster (1E0657-56). The galaxy, originally identified as a multiply imaged source using Infrared Array Camera (IRAC) photometry, has a spectral energy distribution consistent with a highly extincted (AV ~ 3.3), strongly star forming galaxy at z = 2.7. Using our strong gravitational lensing model presented in a previous paper, we find that the magnifications are |μ| 10-50 for the three images of the galaxy. The brightest and faintest images differ by a factor of 3.2 in magnification. The implied infrared luminosity is consistent with the galaxy being a LIRG, with a stellar mass of M * ~ 2 × 1010 M ☉ and a star formation rate (SFR) of ~90 M ☉ yr–1. With lensed fluxes at 24 μm of 0.58 mJy and 0.39 mJy in the two brightest images, this galaxy presents a unique opportunity for detailed study of an obscured starburst with a SFR comparable to that of L* galaxies at z > 2.

Complex backpropagation neural network using elementary transcendental activation functions

Designing a neural network (NN) for processing complex signals is a challenging task due to the lack of bounded and differentiable nonlinear activation functions in the entire complex domain C. To avoid this difficulty, 'splitting', i.e., using uncoupled real sigmoidal functions for the real and imaginary components has been the traditional approach, and a number of fully complex activation functions introduced can only correct for magnitude distortion but can not handle phase distortion. We have previously introduced a fully complex NN that uses a hyperbolic tangent function defined in the entire complex domain and showed that for most practical signal processing problems, it is sufficient to have an activation function that is bounded and differentiable almost everywhere in the complex domain. In this paper, the fully complex NN design is extended to employ other complex activation functions of the hyperbolic, circular, and their inverse function family. They are shown to successfully restore the nonlinear amplitude and phase distortions of non-constant modulus modulated signals.
Identification of Child Sexual Abuse Survivor Subgroups Based on Early Maladaptive Schemas: Implications for Understanding Differences in Posttraumatic Stress Disorder Symptom Severity

Cognitive models have informed understanding of the development, maintenance, and treatment of posttraumatic stress disorder (PTSD). Limited research, however, has examined the relationship of early maladaptive schemas (EMS; Young in Cognitive therapy for personality disorders: A schema-focused approach (rev. ed.). Professional Resource Press, Sarasota, 1994) to PTSD among trauma survivors. The current study, using a sample of 127 female child sexual abuse (CSA) survivors, applied a model-based clustering procedure (Mclust; Fraley and Raftery in MCLUST Version 3 for R: Normal Mixture Modeling and Model-based Clustering, Technical Report No. 504, Department of Statistics, University of Washington, 2006) to the 15 subscales of the Young Schema Questionnaire-Short Form (YSQ-S; Young and Brown in Young Schema Questionnaire- short form. Cognitive Therapy Center, New York, 1994) and revealed three clusters differentiated primarily by level of schema elevation. Women in the cluster characterized by the highest schema scores reported the most severe PTSD symptoms. A discriminant analysis indicated that schemas of Mistrust/Abuse, Vulnerability to Harm, and Emotional Deprivation contributed most to distinguishing women differentiated on the basis of presumptive PTSD diagnostic status. Results underscore the importance of cognitive factors in the development and/or maintenance of PTSD symptoms and suggest possible treatment targets for cognitive therapy with CSA survivors.
Reduction of plasma electron density in a gas ionized by an electron beam: Use of a gaseous dielectric

Propagation of an electron beam through a gas creates a secondary electron/ion plasma which can have subsequent deleterious effects on the propagation of the beam. In the case of pulsed electron beams with short micropulse durations, these effects can be greatly reduced through the use of a small doping fraction of an electron attachment gas. We present a model which allows the calculation of the reduction in unbound plasma electron density attainable with a gaseous dielectric dopant. Potential problems with a dopant, including increased ionization, increased scattering, altered refractive index, and dopant saturation and fragmentation, are discussed.
THE PSILOPEZIOID FUNGI. III. THE GENUS PSILOPEZIA (PEZIZALES)

A B S T R A C T The genus Psilopezia is treated in a restricted sense, limited to three species. Psilopezia is characterized by its flat, appressed apothecia, large ascospores, non-amyloid asci, and bent or deformed paraphyses. The relationship between Psilopezia and Pachyella is discussed. Species are distinguished by the presence or absence of gel in the apothecium, anatomy of the apothecium, size of the apothecium, and by ascospore size. Descriptions, illustrations, and a key are provided for the included species. SINCE ITS ERECTION by Berkeley in 1847, Psilopezia has been an enigma. The sole species then placed in Psilopezia by Berkeley was P. nummularia Berk. This he compared to Pyronema Carus because of the mycelial mat at the base of the dried apothecium of Psilopezia nummularia. This mycelial mat, Berkeley believed, was analogous to the subiculum characteristic of Pyronema. Berkeley and co-authors added four species to Psilopezia: P. babingtonii (Berk. & Br.) Berk., P. flavida Berk. & Curt., P. myrothecioides Berk. & Br., and P. mirabilis Berk. & Curt. None of these species are psilopezias in the restricted sense proposed here. In 1862 the genus Peltidium Kalch., sharing many of the superficial characteristics of Psilopezia, was erected. The nomenclature of Peltidium is discussed elsewhere (Pfister, in press a). Rehm (1904) synonymized Peltidium with Psilopezia.
Development of an optical biosensor using gold nanoparticles and quantum dots for the detection of Porcine Reproductive and Respiratory Syndrome Virus

Current diagnostic methods to detect Porcine Reproductive and Respiratory Syndrome Virus (PRRSV) have many disadvantages and are ill suited for on-site detection of the highly contagious virus, making effective disease eradication difficult. A novel PRRSV detection method is therefore proposed, which utilizes nanophotonic and optical biosensor technology. The biosensor consists of two labeled biomolecule architectures: a PRRSV-specific capture antibody labeled with a fluorescent dye bound to a protein that is labeled with a quantum dot and a PRRSV-specific capture antibody labeled with a fluorescent dye bound to a protein that is labeled with a gold nanoparticle. When exposed to PRRSV, a binding event between the virus particle and antibody takes place, resulting in a conformational change within the biosensor complex that increases the distance between the fluorescent molecules or the fluorescent/quencher molecules. The resulting change in the fluorescence spectrum of the sensor occurs due to a nonradiative signal transduction method, Fluorescence Resonance Energy Transfer (FRET), between the fluorescent dye and the quantum dot or gold nanoparticle. Results have demonstrated that both sensor architectures are able to rapidly and effectively detect PRRSV in solution with a detection limit of 3 particles/μl, illustrating that the optical biosensor is a feasible method for PRRSV detection.
