First Pass Left Ventricular Ejection Fraction by Linear Regression Analysis

A new method for determination of first pass left ventricular ejection fraction (EF) by linear regression analysis using pairs of end-diastolic (ED) and end-systolic (ES) data points has been developed. By rearrangement of the terms in the expression for EF (EF=(ED–ES)/ED), it can be shown that a straight line relationship is obtained between ES and ED, where the slope is equal to 1–EF. We obtained beat-to-beat time-activity curves from first pass left anterior oblique images of the left ventricle (LV) in 9 patients. A LV region of interest was drawn to obtain pairs of ES and ED data points. The slope of the line obtained by plotting these points was obtained from linear regression analysis, and the EF (EFRA) was calculated (EF=1–slope). The EFs were compared to standard left anterior oblique images (EFEQ). The correlation obtained was: EFRA =0.87 EFEQ+5.8 (r=0.99; SEE=2.2%). The regression technique for LVEF determination is accurate, and the correlation coefficient obtained can be used for quality control on first pass EF determinations.
Control of cell division in the cornea of rats. III. Mitogenic effect of isoproterenol and theophylline.

SummaryThe effects of isoproterenol, theophylline and the combination of the two drugs were studied on the circadian mitotic rhythm in rat corneal epithelium. The drugs induced profound alterations in the normal circadian mitotic pattern. The alterations included an initial suppression of cell division, followed by two distinct rises above control; the first immediately following suppression, the second 12-16 hr following drug administration. The second peak of cell division occurred at the circadian trough in controls. The simultaneous administration of isoproterenol and theophylline greatly magnified the effects seen with either drug alone.The authors wish to thank Mrs. Janet Elam for her excellent technical assistance.

Polysomnography in hospitalized patients using a wireless wide area network.

BACKGROUND Sleep-disordered breathing and hypoxemia frequently underlie many common medical conditions for which patients require hospitalization. Sleep apnea is associated with adverse cardiovascular, neurovascular, inflammatory, and metabolic consequences, many of which can be reversed with nasal continuous positive airway pressure. Although polysomnography is the gold standard for outpatient evaluation of sleep apnea, it has not been used for establishing the diagnosis or as a means to intervene with evidence-based therapy in the hospital setting. SETTING A 468-bed tertiary-care facility for adults in which an 801.11b wireless network supplements a typical hardwired local area network. METHODOLOGY We developed a technique to perform 16-channel polysomnography on any patient in any location in the hospital without interfering with routine nursing care. Qualified sleep technicians are able to remotely adjust electrophysiologic and respiratory parameters, as well as control continuous positive airway pressure titration. The study can also be monitored from any location with Internet access using a HIPAA-compliant virtual private network. RESULTS Polysomnography was performed on 51 inpatients (age 26 to 89 years; 31 men). Mean (SD) body mass index measured 34.1 kg/m(2) (12.4). Cardiac disease (47%) and neurologic disease (27%) were the most frequent primary indications for admission. Data acquisition was not disrupted due to connectivity problems. The most frequent deficiencies were reduced sleep time (range 0.8-6.5 hours; mean [SD] 3.3 hours [1.6]) and reduced or absent rapid eye movement sleep. Mean (SD) apnea-hypopnea index measured 35.9 events per hour of sleep (SD 26.3) and 19.4 events per hour of total recording time (SD 17.5). CONCLUSIONS Polysomnography measurements transmitted across a wireless wide area network increases the capacity of the traditional hospital-based sleep laboratory. This technique can facilitate early implementation of appropriate therapy and may reverse underlying factors associated with the primary cause of hospitalization. Indications and standards of practice need to be specifically established for inpatient polysomnography.
Sharing-Aware Outlier Analytics over High-Volume Data Streams

Real-time analytics of anomalous phenomena on streaming data typically relies on processing a large variety of continuous outlier detection requests, each configured with different parameter settings. The processing of such complex outlier analytics workloads is resource consuming due to the algorithmic complexity of the outlier mining process. In this work we propose a sharing-aware multi-query execution strategy for outlier detection on data streams called SOP. A key insight of SOP is to transform the problem of handling a multi-query outlier analytics workload into a single-query skyline computation problem. We prove that the output of the skyline computation process corresponds to the minimal information needed for determining the outlier status of any point in the stream. Based on this new formulation, we design a customized skyline algorithm called K-SKY that leverages the domination relationships among the streaming data points to minimize the number of data points that must be evaluated for supporting multi-query outlier detection. Based on this K-SKY algorithm, our SOP solution achieves minimal utilization of both computational and memory resources for the processing of these complex outlier analytics workload. Our experimental study demonstrates that SOP consistently outperforms the state-of-art solutions by three orders of magnitude in CPU time, while only consuming 5% of their memory footprint - a clear win-win. Furthermore, SOP is shown to scale to large workloads composed of thousands of parameterized queries.
Zlotys, Rubles, and Leks

The most remarkable change between the fifth and sixth editions of this book has been the collapse of ‘The Evil Empire.’ The Berlin Wall has disappeared, East Europe has been rechristened Central Europe, and the USSR — the Union of Soviet Socialist Republics — is no more, replaced by the CIR — the Committee of Independent Republics. The Baltic Countries — Estonia, Latvia, and Lithuania — have regained the independence they lost in 1939. Ukrania and Russia squabble over who owns the Black Sea fleet., and there is a continual concern over the command and control of hundreds of nuclear missiles in countries that often appear to be on the edge of disintegration.
Mechanical Ventilation in Traumatic Brain Injury

Mechanical ventilation is frequently required in the management of brain-injured patients. Common indications include pulmonary contusions, acute respiratory distress syndrome, neurogenic pulmonary edema, pneumonia, fluid overload, airway compromise from depressed mental status, and need for sedatives to facilitate procedures and control intracranial pressure. Cautious management of mechanical ventilation is required to avoid secondary injury from hypoxemia, hypo-or hypercarbia, or decreases in cerebral perfusion pressure. Optimal ventilator management utilizes a “lung protective” strategy that emphasizes adequate positive end expiratory pressure in concert with low tidal volumes and plateau pressures to prevent ventilator-induced lung injury. This strategy can be safely applied in the majority of brain-injured patients. Patients with concurrent severe acute respiratory distress syndrome and traumatic brain injury present a significant therapeutic challenge, as it may be difficult to maintain adequate oxygenation and an appropriate carbon dioxide level without injurious ventilator settings. Strategies that have been successfully applied in this patient population include airway pressure release ventilation, prone positioning, and extracorporeal lung support techniques, although none of these methods have been validated in prospective trials in this specific population.
An On-Chip Electromagnetic Bandgap Structure with ESD Protection for Noise Suppression in 16-nm FinFET CMOS

By using periodical electromagnetic bandgap (EBG) structure, a wideband band-stop filter (BSF) with ESD protection is first realized in 16-nm FinFET CMOS technology for GHz-order noise suppression. The proposed EBG unit cell consists of an on-chip inductor in series with MOS capacitors and gated ESD diodes. The gated ESD diodes are not only used as ESD protection devices, but also co-designed with MOS capacitors and an inductor to form LC resonator for the BSF. The measurement results demonstrate TLP currents of 1.75 A and 1.35 A for the PDS and NDS modes, respectively, corresponding to a HBM ESD level over 2 kV. With the consideration of metal density rule for power/ground mesh, the on-chip EBG array presents a stopband of 15.5 GHz, from 4.5 to 20 GHz, with an isolation level of 30 dB.
Independent Maternal and Fetal Genetic Effects on Midgestational Circulating Levels of Environmental Pollutants.

Maternal exposure to environmental pollutants could affect fetal brain development and increase autism spectrum disorder (ASD) risk in conjunction with differential genetic susceptibility. Organohalogen congeners measured in maternal midpregnancy blood samples have recently shown significant, but negative associations with offspring ASD outcome. We report the first large-scale maternal and fetal genetic study of the midpregnancy serum levels of a set of 21 organohalogens in a subset of 790 genotyped women and 764 children collected in California by the Early Markers for Autism (EMA) Project. Levels of PCB (polychlorinated biphenyl) and PBDE (polybrominated diphenyl ether) congeners showed high maternal and fetal estimated SNP-based heritability (h2g ) accounting for 39-99% of the total variance. Genome-wide association analyses identified significant maternal loci for p,p'-DDE (P = 7.8 × 10-11) in the CYP2B6 gene and for BDE-28 (P = 3.2 × 10-8) near the SH3GL2 gene, both involved in xenobiotic and lipid metabolism. Fetal genetic loci contributed to the levels of BDE-100 (P = 4.6 × 10-8) and PCB187 (P = 2.8 × 10-8), near the potential metabolic genes LOXHD1 and PTPRD, previously implicated in neurodevelopment. Negative associations were observed for BDE-100, BDE153, and the sum of PBDEs with ASD, partly explained by genome-wide additive genetic effects that predicted PBDE levels. Our results support genetic control of midgestational biomarkers for environmental exposures by nonoverlapping maternal and fetal genetic determinants, suggesting that future studies of environmental risk factors should take genetic variation into consideration. The independent influence of fetal genetics supports previous hypotheses that fetal genotypes expressed in placenta can influence maternal physiology and the transplacental transfer of organohalogens.

Letters to Children: Findings of a Program to Enhance Communication of Incarcerated Mothers and Their Children

ABSTRACTThere is a scarcity of studies exploring treatment modalities specifically designed for the incarcerated mother. This paper presents findings from a program designed to help incarcerated mothers develop their ability to communicate and subsequently bond with their children by engaging in group discussions during a letter-writing process. Using mixed research methods from 16 incarcerated mothers, the participants reported (1) gaining insight into personal emotions and strengths around parenting, (2) strengthening of positive parenting strategies, (3) increasing ability to empathize with their children, and (4) increasing tools to enhance communication. The quantitative data showed significant improvement in the areas of seeing themselves as better parents and decreasing anxiety around parenting issues. The participants gave feedback for models developed for incarcerated mothers.
A cascaded lattice Boltzmann model for thermal convective flows with local heat sources

Abstract A cascaded central moment based lattice Boltzmann (LB) method for solving low Mach number thermal convective flows with source terms in two-dimensions in a double distribution function framework is presented. For the passive temperature field, which satisfies the convection diffusion equation (CDE) with a source term to represent internal/external local heat source, a new cascaded collision kernel is presented. Due to the use of a single conserved variable in the thermal energy equation, the cascaded structure in its collision operator begins from the first order moments and evolves to higher order moments. This is markedly different from the collision operator for the fluid flow equations, constructed in previous work, where the cascaded formulation starts at the second order moments in its collision kernel. A consistent implementation of the spatially and temporally varying source terms in the thermal cascaded LB method representing the heat sources in the CDE that maintains second order accuracy via a variable transformation is discussed. The consistency of the thermal cascaded LB method including a source term for the D2Q9 lattice with the macroscopic convection–diffusion equation is demonstrated by means of a Chapman–Enskog analysis. The new model is tested on a set of benchmark problems such as the thermal Poiseuille flow, thermal Couette flow with either wall injection or including viscous dissipation and natural convection in a square cavity. The validation study shows that the thermal cascaded LB method with source term is in very good agreement with the analytical solutions or numerical results reported for the benchmark problems. In addition, the numerical results show that our new thermal cascaded LB model maintains second order accuracy.

Reducing the Risk of Diabetes and Metabolic Syndrome With Exercise and Physical Activity

Abstract The literature strongly supports the benefits of exercise and physical activity as core components in the prevention of metabolic syndrome and type 2 diabetes. Exercise and physical activity enhance insulin sensitivity and glycemic control, reduce blood pressure, improve dyslipidemia, and produce beneficial changes in body mass and composition. Based on the literature, structured aerobic and resistive exercise programs, as well as leisure time and physical activity of moderate or vigorous intensity, are effective in preventing the onset of type 2 diabetes and metabolic syndrome. A challenge in combating diabetes and metabolic syndrome appears to lie in developing effective public health approaches that support individuals in their attempt to incorporate the necessary lifestyle changes into their daily routine and maintain these changes for life.
Linking genes and environmental exposure: why China presents special opportunities.

The Human Genome Project will have an enormous impact on our ability to study and understand human disease by providing maps of human genes. However, many of the most prevalent human diseases result from the complex interaction of numerous genes. Even with the use of a catalogue of human genes, the task of analyzing complex genetic and environmental interactions involved in the common human disorders will be formidable. Due to its demographic specificities and large size, the Chinese population offers a unique resource for the study of human genetics and the ability to capitalize upon the recent revolution in biotechnology. Reasons that China provides an exceptional population for genetic studies of complex diseases include: (i) the resource of 1.3 billion people makes obtaining a large number of subjects with rare (and common) diseases possible; (ii) relative genetic homogeneity in many regions has been preserved; (iii) stratification is distinct; (iv) urban/rural and geograph ic contrasts, both in environmental factors and disease occurrence, are quite marked; (v) family members tend to stay congregated; and (vi) epidemiologic study is cost-beneficial.
A Profit System Model of the Firm for Business Analysis and Stock Valuation

As discussed in Chapter 2, dynamic relationships exist between sales (output), profit, profit rate, profit margin, and capital stocks of firms – that is, the values (magnitudes) of these fundamental variables in any period depend on the current and past values of the other variables. Consequently, for purposes of business analysis, an integrated business model of firms must contain all the dynamic relationships among these variables. Our profit system models in Chapter 2 provide analytical frameworks for short-run and long-run analyses of these fundamental variables over time. Here we apply the profit system model to individual firms for business analysis, forecasting, and stock market valuation. Regarding stock market valuation, we integrate the profit system model and the popular discounted cash flow (DCF) stock valuation model to perform in-sample analyses and out-of-sample forecasts of individual firms’ stock values.
Neural Semantic Parsing

Semantic parsing, the study of translating natural language utterances into machine-executable programs, is a well-established research area and has applications in question answering, instruction following, voice assistants, and code generation. In the last two years, the models used for semantic parsing have changed dramatically with the introduction of neural encoder-decoder methods that allow us to rethink many of the previous assumptions underlying semantic parsing. We aim to inform those already interested in semantic parsing research of these new developments in the field, as well as introduce the topic as an exciting research area to those who are unfamiliar with it. Current approaches for neural semantic parsing share several similarities with neural machine translation, but the key difference between the two fields is that semantic parsing translates natural language into a formal language, while machine translation translates it into a different natural language. The formal language used in semantic parsing allows for constrained decoding, where the model is constrained to only produce outputs that are valid formal statements. We will describe the various approaches researchers have taken to do this. We will also discuss the choice of formal languages used by semantic parsers, and describe why much recent work has chosen to use standard programming languages instead of more linguistically-motivated representations. We will then describe a particularly challenging setting for semantic parsing, where there is additional context or interaction that the parser must take into account when translating natural language to formal language, and give an overview of recent work in this direction. Finally, we will introduce some tools available in AllenNLP for doing semantic parsing research.
Internal Validation of a Predictive Model for Complications After Total Hip Arthroplasty.

Abstract Background Total hip arthroplasty (THA) is projected to increase in prevalence and associated complications will impose significant cost on the US healthcare system. The purpose of this study is to validate a predictive model for postoperative complications utilizing a novel 11-component hip-specific questionnaire encompassing preoperatively available clinical and radiographic data. Methods Consecutive primary THA patients between January 2014 and January 2016 were included. Exclusion criteria included patients without questionnaire scoring variables and less than 1-year follow-up. Patients were stratified into 4 tiers based on their questionnaire score: low risk (>74), mild risk (57-73), moderate risk (41-56), and high risk ( Results Four hundred fifty patients were included in the final analysis with a mean (range) follow-up of 2.1 years (1.0-5.9), age of 63.1 years (25.7-9.17), and body mass index of 31.7 kg/m2 (17.8-64.5). The complication rate was 13.6%. A hip questionnaire score of 73.8 conferred a 98.5% sensitivity and 98.5% negative predictive value for complications. The questionnaire score was the strongest predictor of a decreased complication likelihood (odds ratio 0.94, 95% confidence interval 0.90-0.97, P Conclusion This novel hip questionnaire demonstrated a high sensitivity and negative predictive value to identify patients at risk for postoperative complications. Future studies should attempt to prospectively validate the use of this questionnaire.

Validity and Reliability of the GymAware Linear Position Transducer for Squat Jump and Counter-Movement Jump Height.

The purpose of this study was to assess the concurrent validity and test-retest reliability of a linear position transducer (LPT) for the squat jump (SJ) and counter-movement jump (CMJ) height. Twenty-eight subjects (25.18 ± 7.1 years) performed three SJs followed by three CMJs using a force plate concurrently with the LPT to test validity. Subjects returned on a separate day, at least 48 h apart, to measure test-retest reliability. A t-test showed a significant difference between the two devices for both SJ (p < 0.001) and CMJ (p < 0.001) while Bland–Altman analysis for validity revealed that the LPT overestimated jump height for both SJ (mean difference (MD) = 8.01 ± 2.93 cm) and CMJ (MD = 8.68 ± 2.99 cm). With regards to reliability of the LPT, mean intraclass correlation (ICC) for both SJ (ICC = 0.84) and CMJ (ICC = 0.95) were high, and Bland–Altman analysis showed mean differences lower than minimal detectable change (MDC) between the days for both SJ (MD = 1.89 ± 4.16 cm vs. MDC = 2.72 cm) and CMJ (MD = 0.47 ± 3.23 cm vs. MDC = 2.11 cm). Additionally, there was a low coefficient of variation (CV) between days for both SJ (CV = 3.25%) and CMJ (CV = 0.74%). Therefore, while the LPT overestimates jump height, it is a reliable tool for tracking changes in jump height to measure performance improvement and monitor fatigue.
MUC16 gene up-regulates gene transcripts associated with cisplatin resistance in human ovarian cancer cells

2327 Serum marker CA125 has been used as a measure of ovarian cancer disease progression and therapeutic response for over two decades. The underlying mechanism for the release of CA125 and which factors trigger the release is poorly understood. The gene that encodes the CA125 glycoprotein, MUC16, has been previously identified and sequenced (Yin, 2001; O’Brien, 2001). MUC16 has a molecular size of 22,000 base pairs and consists of a cytoplasmic domain, a transmembrane region and an external domain of up to 60 tandem repeats. The large molecular weight of this gene has made it difficult to study and track in a cell. In an attempt to better understand this gene, we have designed individual DNA constructs for the multiple components of the MUC16 gene. Three gene constructs were created which encode for the cytoplasmic domain (CD), the one (1R) and the two (2R) external domain tandem repeats. Individual constructs were fused with Vitality phrGFP II C vector system and were successfully transfected into three CA125 negative ovarian cell lines; SKOV3, A2780 and T80. Stable transfectants were made and enriched by cell sorting for GFP. The transfectants were confirmed by FACS analysis with antibodies to GFP and human OC125 which recognizes only the external domain consisting of tandem repeats. The culture supernatants of these transfectants were tested periodically for CA125 by ELISA. Sensitivity to cisplatin (CDDP) was tested by alamar blue cytotoxicity assays on all the stable transfectants. In vitro invasive potential was examined by the Matrigel invasion assay. RT-PCR Super Arrays for 88 human cancer drug resistance & metabolism genes were performed with cDNA’s from these stable transfectants to examine the regulation of drug resistance genes. Protein profiles for the genes involved were confirmed by western blot analysis. FACS analysis was performed for apoptosis assay using Annexin V and 7AAD staining on all stable transfectants. The SKOV3 stable transfectants with 1 and 2 repeats had increased CA125 secretion to 4 and 7 units/ml, respectively.SKOV3, A2780 and T80 stable transfectants showed a modest increased resistance to CDDP compared to vector control. In vivo tumor growth specifically with SKOV3 1R-GFP transfected cell line in athymic nude mice showed a marked resistance to CDDP compared to the vector control. Matrigel invasion assay with SKOV3 transfectants demonstrated a more invasive potential than vector only (1R = 36% vs Vector = 15% invasion). Transcripts for 19 drug resistance & metabolism genes were significantly up-regulated 3-23 fold (p
A Cascode Switching Technique for Highly Efficient Stacked Class E PA

In this paper, technology fundamental limits on the performance of double stacked Class E power amplifiers are studied, and the drawbacks of the conventional topology are highlighted. A novel cascode switching technique is proposed in order to mitigate the loss caused by these drawbacks. The theory is carried to design a power amplifier (PA) at 15 GHz using 0.13u CMOS technology. A comparison is performed with a classic double stacked design. Simulation results show enhancement in both output power and power added efficiency by about 9% and 10.6% respectively.
Sacropelvic Fixation: A Comprehensive Review.

Abstract Sacropelvic fixation is indicated in various clinical settings, most notably long spinal arthrodesis, reduction of high-grade spondylolisthesis, and complex sacral fractures. The sacropelvis is characterized by complex regional anatomy and poor bone quality. These factors make achieving solid fusion across the lumbosacral junction challenging. However, a better understanding of spinal biomechanics at that level has led to much higher fusion rates than those of the past. The newer fixation techniques are biomechanically superior to previous methods mainly because they achieve bony purchase anterior to the pivot point—first described by McCord et al. in 1994. Today, the two most widely used fixation techniques are iliac screws and S2-alar-iliac screws. Although these techniques are associated with very high rates of fusion, instrumentation-related pain and reoperation remain problematic. This review provides an overview of the regional anatomy and biomechanics at the lumbosacral junction, as well as a summary of fixation techniques with an emphasis on the most widely used techniques today.

Are shared models always cultural models? A study of the cultural model of affect and emotion in Chuuk

This article investigates a theoretical tension in cultural models theory between their sharedness and their origin in social and culturally mediated experiences. To address this tension empirically, this article presents a mixed-methods analysis of the shared understanding of a typology of emotion in Chuuk Lagoon. Based on a review of contemporary theory, one would expect that while people in Chuuk would have distinct cultural models for specific culturally meaningful paradigmatic emotions, the shared model for the entire typology of emotion would be structured by two universal dimensions of core affect (arousal and hedonic quality). But this theoretical literature ignores the importance of an intersubjective dimension of prereflective experience. This dimension may be culturally muted in industrial, educated, and rich contexts where most prior research has been conducted but culturally emphasized in places like Chuuk. The mixed-methods analysis finds that an intersubjective dimension along with a hedonic quality dimension structures the shared model of a typology for affect and emotion in Chuuk, while the arousal dimension found elsewhere is muted. Thus, shared models of affect and emotion are cultural models both in terms of specific, culturally elaborated emotions and in terms of the cultural emphasis given to underlying affective and intersubjective dimensions.
Reworking recognition: Indigeneity, land rights, and the dialectics of disruption in Paraguay’s Chaco

Abstract This paper discusses the limits of recognition by investigating the politics of Indigenous rights in Paraguay. The “multicultural turn” of the 1980s–1990s promised to disrupt historical patterns of Indigenous dispossession through land titling initiatives across the Americas, yet as this case shows, recognition comes without guarantees. I draw from ethnographic research with the Xakmok Kasek Indigenous community in Paraguay’s Chaco to consider how Sanapana and Enxet-Sur Indigenous peoples are reworking the limits of recognition to disrupt settler colonial power. Rather than rejecting or refusing recognition, I argue that the Xakmok Kasek community now employs a dialectics of refusal and engagement that rewrites the terms of recognition, subsequently forcing state officials to reconcile with new articulations of indigenous self-determination that disrupt settler colonial power. Focusing on the dialectics of refusal and engagement brings nuance to the complex negotiations and evolving strategies of resistance that Indigenous peoples are employing to challenge the status quo of dispossession in pursuit of decolonial futures across the Americas, futures shaped by historic processes that draw humans and non-humans together in place to maintain existing relations and form new ones in pursuit of more just geographies This article, therefore, contributes to ongoing debates about the politics of recognition, post-multiculturalism, and decolonial geographies by bringing a focus on Latin America more fully into dialogue with analyses of settler colonial geographies in North America and Australia.

Revascularization Practices and Outcomes in Patients With Multivessel Coronary Artery Disease Who Presented With Acute Myocardial Infarction and Cardiogenic Shock in the US, 2009-2018

Importance Cardiogenic shock after acute myocardial infarction (AMI) is associated with high mortality, particularly among patients with multivessel coronary artery disease. Recent evidence suggests that use of multivessel percutaneous coronary intervention (PCI) may be associated with harm. However, little is known about recent patterns of care and outcomes for this patient population. Objective To evaluate patterns in the use of multivessel PCI vs culprit-vessel PCI in AMI and cardiogenic shock and outcomes in the US from 2009 to 2018. Design, Setting, and Participants This cohort study identified all patients in the CathPCI Registry) with AMI and cardiogenic shock who had multivessel coronary artery disease and underwent PCI between July 1, 2009, and March 31, 2018. Exposures Multivessel or culprit-vessel PCI for AMI and shock. Primary Outcomes and Measures The primary outcome was in-hospital mortality. Temporal trends and hospital variation in PCI strategies were evaluated, while accounting for differences in case mix using hierarchical models. As a secondary outcome, the association of PCI strategy with postdischarge outcomes was evaluated in the subset of patients who were Medicare beneficiaries. Results Of 64 301 patients (mean [SD] age, 66.4 [12.5] years; 20 366 [31.7%] female; 54 538 [84.8%] White) with AMI and shock at 1649 US hospitals, 34.9% had primary multivessel PCI. In the subgroup of 48 943 patients with ST-segment elevation myocardial infarction (STEMI), 31.5% underwent multivessel PCI. Between 2009 and 2018, this percentage increased by 6.7% per year for AMI and 5.8% for STEMI. Overall, multivessel PCI was associated with a greater adjusted risk of in-hospital complications (odds ratio [OR], 1.18; 95% CI, 1.14-1.23) and with greater in-hospital mortality in patients with STEMI (OR, 1.11; 95% CI, 1.06-1.16). Among Medicare beneficiaries, multivessel PCI use was not associated with postdischarge 1-year mortality (51.5% vs 49.8%; risk-adjusted OR, 0.97; 95% CI, 0.90-1.04;P = .37). Significant hospital variation was found in the use of multivessel PCI, with a higher multivessel PCI rate for similar patients across hospitals (median OR, 1.37; 95% CI, 1.33-1.41). Patients at hospitals with high rates of PCI in STEMI use had higher risk-adjusted in-hospital mortality (highest vs lowest hospital multivessel PCI quartile: OR, 1.10; 95% CI, 1.02-1.19). Conclusions and Relevance This cohort study found that multivessel PCI was increasingly used as the revascularization strategy in AMI and shock and that hospitals that used multivessel PCI more, especially among patients with STEMI, had worse outcomes. With recent evidence suggesting harm with this strategy, there appears to be an urgent need to change practice and improve outcomes in this high-risk population.

Maternal Depression and Children's Growth: Data From Brazil.

Physical growth is considered one of the most important indicators of child health. Stunting caused by undernutrition is indirectly responsible for more than half of deaths among young children globally and can have adverse developmental repercussions. Until recently, research on risk factors for suboptimal growth has focused primarily on micronutrient deficiencies and child illness, with little attention paid to potential social predictors such as maternal mental health. The current presentation summarizes the 1) results of a child health study from Brazil showing an association between maternal depressive symptoms and stunting in children under two years of age, 2) similar findings from a systematic review and meta-analysis that pooled results from seventeen studies in eleven low- and middle- income countries, 3) results from a longitudinal US representative sample that found maternal depressive symptoms at nine months postpartum related to an increased odds of a child being

Interfacial Adsorption of Surfactants in the Presence of Polymers and its Effect on Mineral Flotation

Effect of anionic and cationic Polyacrylamides on the adsorption of sodium dodecylsulfonate and dodecylamine hydrochloride on hematite and silica was investigated under different conditions of pH and reagent concentration. It was determined that although the amount of surfactant adsorbed on hematite and silica essentially remained independent of the nature and amount of the polymer added, the surface charge characteristics as well as the interfacial properties such as water wettability of the particles were largely governed by the hydrophilic nature of the polymer molecules. In contrast, the amount of polymer adsorbed on hematite was found to be significantly affected by the charge characteristics of the surfactant species, the surfactant concentration, and the order of reagent addition. Results of adsorption studies and zeta potential measurements are discussed to elucidate the factors governing the surface wettability when both polymer and surfactant species are present in the system. Flotation test results are presented to confirm the changes in the wettability characteristics of particles in the presence of polymer species.
Wetting, Deagglomeration, and Adsorption

This chapter discusses the thermodynamic principles of wetting of a ceramic powder by a liquid as a first step for its dispersion in the liquid. Once the ceramic powder is dispersed in the liquid, the powder must be de-agglomerated by grinding, mixing, or ultrasonics. De-agglomeration can take place by two methods: comminution and ultrasonification. Ultrasonics is most often utilized for powder de-agglomeration in the laboratory. This technique is frequently used with submicron-sized powders that are hard to disperse by other methods. When a liquid is exposed to progressively higher ultrasonic powder, small vapor bubbles start to appear above a certain level of threshold energy. A simplified model for ultrasonic dispersion was presented. Once the powder is de-aggomerated it must be protected from re-agglomeration by the adsorption of the solvent, an ion, a surfactant, or a polymer at the newly formed surface. Various solvent and surfactant selection schemes and the chemical stability of a ceramic powder in a solvent system have been discussed in the chapter.
Nerve Regeneration: Mammalian

Nerve regeneration is strictly the regrowth of an axon following injury. The term is also used more broadly, however, to cover collateral sprouting, neural plasticity, protection from secondary tissue injury, reconstitution of supporting tissues and transplantation. Keywords: axonal regeneration; sprouting; growth factors; functional recovery
Vehicle-Infrastructure Cooperative Systems for Intersection Collision Avoidance: Driver Assessment Challenges

According to National Highway Traffic Safety Administration (NHTSA, 1998) data, there were 37,280 crashes that involved fatalities in 1997. Of these crashes, 8,571 were related to intersections. The fatal crashes at intersection were about evenly divided among non-controlled intersections, signal controlled intersections, and stop sign controlled intersection. In addition to fatal crashes, almost 1 million injury crashes occur at intersections annually, and there are about 1.7 million police reported crashes at intersection each year. Various programs have proposed alternative countermeasures to reduce the number of crashes and fatalities at intersections. Conventional countermeasures such as protected left turn signals are effective and fairly well understood. However, these countermeasures alone will not eliminate intersection crashes because they do not address factors such as willful and unintentional red-light and stop sign violations, gap acceptance problems associated with older drivers, and sight distance problems at intersections that may not warrant traffic signals. The Federal Highway Administration is pursuing infrastructure based ITS solutions to address crashes at intersections. Initially these solutions will not require changes to vehicles. It is anticipated that in the future, some of these solutions could be integrated into in-vehicle ITS systems to enable either in-vehicle warnings or automated crash avoidance systems. Four types of intersection-infrastructure systems are envisioned: (1) traffic signal violation warning, (2) stop sign violation warning, (3) traffic signal left turn assistance, and (4) stop sign movement assistance. Each of these systems is described briefly, and a preliminary list of the driver behavior issues associated with each is identified. The challenge for the design of these systems is similar to that for other areas of highway and vehicle design - how to assess driver performance and behavior with these systems before the systems are fielded. Various assessment techniques are discussed in association with the advantages and disadvantages of each. The FHWA human-centered research approach for intersection-infrastructure solutions is presented. For the covering abstract see ITRD E113119.
Interactions of 13.6-GeV/nucleon O-16 and Si-28 with carbon, aluminum, and copper

Cross sections for forming $^{24}\mathrm{Na}$ and $^{18}\mathrm{F}$ by the interactions of 13.6-GeV/nucleon $^{16}\mathrm{O}$ and $^{28}\mathrm{Si}$ ions with Al and for forming $^{24}\mathrm{Na}$ in $^{16}\mathrm{O}$ interactions with Cu have been measured relative to the cross section for forming $^{11}\mathrm{C}$ from carbon. The results are generally consistent with energy-independent inclusive cross sections (limiting fragmentation) for heavy ions between \ensuremath{\sim}2 and 13.6 GeV/nucleon. However, comparison of the heavy-ion data with those for high-energy protons indicates a significantly weaker dependence on projectile size than that predicted by the factorization hypothesis for ${\mathrm{\ensuremath{\sigma}}}_{\mathrm{C}}$${(}^{11}$C), ${\mathrm{\ensuremath{\sigma}}}_{\mathrm{Al}}$${(}^{18}$F), and ${\mathrm{\ensuremath{\sigma}}}_{\mathrm{Al}}$${(}^{24}$Na). The dependence is slightly stronger in the case of ${\mathrm{\ensuremath{\sigma}}}_{\mathrm{Cu}}$${(}^{24}$Na).
Evaluation of Accuracy of Multitest Micromethod System for Identification of Enterobacteriaceae

The Analytab system of 20 biochemical tests for identification of Enterobacteriaceae was evaluated in parallel with conventional tests on 128 Enterobacteriaceae, 5 Aeromonas, and 1 Yersinia enterocolitica. The results of tests for H2S and indole production, citrate utilization, lysine and ornithine decarboxylase, arginine dihydrolase, nitrate reduction, β-galactosidase, and fermentation of arabinose, rhamnose, mannitol, and glucose showed almost complete agreement between the two systems. Eighty-eight per cent of Enterobacteriaceae were correctly speciated with the Analytab system; on repeat testing with heavier inocula of organisms failing to ferment glucose initially, the proportion of Enterobacteriaceae correctly speciated became 93%.
Spline-based nonlinear controller for the Duffing oscillator

The forced Dulling oscillator is a mathematical model of the nonlinear pendulum. It is formulated by a second-order, nonlinear, nonautonomous, ordinary differential equation. First, a review of designing a nonlinear controller with an exact feedback linearization method is given. Then a spline method is used to mimic the controller which drives a state of the Duffing system toward a desired path. The spline-based nonlinear controller has piecewise polynomial segments with different order of polynomials on each segment for example linear, quadratic and cubic. The cubic spline allows each segment to have a unique cubic polynomial while constraining the curve fit to the data properties. Controller efforts for different orders of polynomial interpolants and power spectral densities of the controller signals are compared with the exact feedback linearization method.
The June Phenomenon and the Changing Month of the Year Effect

Mean June return of the U.S. stock market is significantly negative since 2001 and the phenomenon is more apparent for large stocks. June return is negatively related to returns of all the other months and the coefficients are all statistically significant except for January and August, and June return is significantly negatively related to change in short interest. Meanwhile, April is the best month for the DJIA and S&P 500 and October is the best for the NASDAQ. The purpose of this study is to reveal the worst month of the U.S. stock markets in the new century and the dynamics of the month-of-the-year anomaly.
Long term black hole evolution with the BSSN system by pseudospectral methods

We present long term evolutions of a single black hole of mass M with the Baumgarte-Shapiro-Shibata-Nakamura (BSSN) system using pseudospectral methods. For our simulations we use the SGRID code where the BSSN system is implemented in its standard second order in space form. Previously we found that such simulations are quite unstable. The main goal of this paper is to present two improvements which now allow us to evolve for longer times. The first improvement is related to the boundary conditions at the excised black hole interior. We now use a gauge condition that ensures that all modes are going into the black hole, so that no boundary conditions are needed at the excision surface. The second more significant improvement has to do with our particular numerical method and involves filters based on projecting the double Fourier expansions used for the angular dependence onto spherical harmonics. With these two improvements it is now easily possible to evolve for several thousand M. The only remaining limitation seems to be the radiative outer boundary conditions used here. Yet this problem can be ameliorated by pushing out the location of the outer boundary, which leads to even longer run times.
