ABSTRACTThis article reviews the history of recreational, arts, and music-based activities in social work with groups, providing a nondeliberative practice context. The article begins with an overview of nondeliberative practice, then presents various uses of recreational, art, and music-based activities during the Settlement House and Recreational Movements, in mid-20th-century group work practice and in present practice. The article concludes with a review of current projects in the Chicago land area and highlights their potential to decrease young person on young person violence.
Direct conversion of h-BN into c-BN and formation of epitaxial c-BN/diamond heterostructures

We have created a new state of BN (named Q-BN) through rapid melting and super undercooling and quenching by using nanosecond laser pulses. Phase pure c-BN is formed either by direct quenching of super undercooled liquid or by nucleation and growth from Q-BN. Thus, a direct conversion of hexagonal boron nitride (h-BN) into phase-pure cubic boron nitride (c-BN) is achieved by nanosecond pulsed laser melting at ambient temperatures and atmospheric pressure in air. According to the P-T phase diagram, the transformation from h-BN into c-BN under equilibrium processing can occur only at high temperatures and pressures, as the hBN-cBN-Liquid triple point is at 3500 K/9.5 GPa or 3700 K/7.0 GPa with a recent theoretical refinement. Using nonequilibrium nanosecond laser melting, we have created super undercooled state and shifted this triple point to as low as 2800 K and atmospheric pressure. The rapid quenching from super undercooled state leads to the formation of a new phase, named as Q-BN. We present detailed ...
Protocol-guided analysis of post-silicon traces under limited observability

We consider the problem of reconstructing system-level behavior of an SoC design from a partially observed signal trace. Solving this problem is a critical activity in post-silicon validation, and currently depends primarily on human creativity and insights. In this paper, we provide an algorithm to automatically infer system-level transactions from incomplete, ambiguous, and noisy trace data. We demonstrate the approach on a multicore virtual platoform developed within the GEM5 environment.
Comparative biochemical and cytogenetic studies of childhood acute lymphoblastic leukemia with the Philadelphia chromosome and other 22q 11 variants

We studied the relationship of direct karyotypes, determined at diagnosis and remission, to Abelson-related tyrosine kinase activity and the cytogenetic features of erythroid and myeloid colonies derived from remission marrow of six children with acute lymphoblastic leukemia (ALL). These patients had either the characteristic Philadelphia chromosome (Ph1) [t(9;22)(q34;q11)] or cytogenetically similar variants with a 22q11 breakpoint but no detectable cytogenetic involvement of 9q34. The findings suggested two distinct subtypes of ALL: one defined by t(9;22)(q34;q11) and expression of P185BCR-ABL tyrosine kinase and one with variant karyotypes and no P185BCR-ABL expression. The former comprises cases with Ph1 + marrow cells and Ph1 + erythroid and (or) myeloid colonies in remission marrow and others in which the t(9;22) is undetectable in remission marrow cells. In the latter subgroup, the disease may reflect more extreme mosaicism with a similar stem cell that is cytogenetically undetectable. Variant karyotypes included a del(22)(q11) in one patient and a t(6;22;15;9) (q21 ;q11 ;q?22;q21) in another: in both instances, the malignant blast cells lacked P185 BCR-ABL expression. Thus ALL with t(9;22)(q34;q11) should be distinguished from ALL with other involvement of the 22q11 breakpoint by molecular studies including protein expression. The diversity of karyotypic findings in cases with involvement of 22q11 suggests at least two mechanisms of leukemogenesis in patients with ALL defined by this breakpoint.© 1989 by Grune & Stratton, Inc. 0006-4971/89/7305-0028$3.00/0
Comments on the 6th Report of the Joint American Committee on the Diagnosis and Treatment of Arterial Hypertension

The new guidelines of the Joint American Committee for the diagnosis and treatment of high blood pressure emphasize the importance of improving the detection of the disease, and optimizing the treatment. The new classification of high blood pressure includes < 120/89 mmHg as optimum blood pressure goal, and for patients with diabetes or existing cardiac disease the blood pressure goal should be reduced to 130/85 mmHg. In this sense, the report also focuses on the need of accomplishing a diagnostic and therapeutic target of the global cardiovascular risk of the patient, taking into account other pathological situations.
THE BLOB CONNECTION: SEARCHING FOR LOW CORONAL SIGNATURES OF SOLAR POST-CME BLOBS

Bright linear structures, thought to be indicators of a current sheet (CS), are often seen in Large Angle and Spectrometric Coronagraph (LASCO) on the Solar and Heliospheric Observatory (SOHO) white-light data in the wake of coronal mass ejections (CMEs). In a subset of these post-CME structures, relatively bright blobs are seen moving outward along the rays. These blobs have been interpreted as consequences of the plasmoid instability in the CS, and can help us to understand the dynamics of the reconnection. We examine several instances, taken largely from the SOHO/LASCO CME-rays Catalog, where these blobs are clearly visible in white-light data. Using radially filtered, difference, wavelet enhanced, and multiscale Gaussian normalized images to visually inspect Solar Dynamics Observatory/Atmospheric Imaging Assembly (AIA) data in multiple wavelengths, we look for signatures of material that correspond both temporally and spatially to the later appearance of the blobs in LASCO/C2. Constraints from measurements of the blobs allow us to predict the expected count rates in DN pixel−1 s−1 for each AIA channel. The resulting values would make the blobs bright enough to be detectable at 1.2 R ⊙. However, we do not see conclusive evidence for corresponding blobs in the AIA data in any of the events. We do the same calculation for the "cartwheel CME," an event in which blobs were seen in X-rays, and find that our estimated count rates are close to those observed. We suggest several possibilities for the absence of the EUV blobs including the formation of the blob higher than the AIA field of view, blob coalescence, and overestimation of blob densities.
Observing the uncoupling of electron motion from the molecular frame in photoelectron angular distributions

We observe the uncoupling of an electron's motion from the molecular frame through angle-resolved photoelectron imaging of a Rydberg orbital of N 2 . This allows for ultrafast measurements in a distinct regime of non-Born-Oppenheimer molecular dynamics.
Innovative application of metal-organic frameworks for encapsulation and controlled release of allyl isothiocyanate.

This research investigated the technical feasibility of metal-organic frameworks (MOFs) as novel delivery systems for encapsulation and controlled release of volatile allyl isothiocyanate (AITC) molecules. We hypothesized that water vapor molecules could act as an external stimulus to trigger the release of AITC molecules encapsulated in MOFs. To test this hypothesis, three MOFs—HKUST-1, MOF-74(Zn), and RPM6-Zn—were selected based on their structural properties and AITC molecular characteristics. Results from adsorption-desorption and GC headspace analyses showed that these MOFs could encapsulate and retain AITC molecules within their pores under low (30–35%) relative humidity (RH) conditions. In contrast, the release of AITC molecules from all these MOFs was triggered under high RH (95–100%) conditions. These findings along with results from SEM, TEM, and XRPD studies support our hypothesis that water vapors could trigger the AITC release from these MOFs, indicating that development of the AITC-MOFs delivering system is technically feasible.

Genome-wide association studies of cancer in diverse populations

Genome-wide association studies (GWAS) of cancer have identified more than 700 risk loci, of which ~80% of were first discovered in European ancestry populations, ~15% in East Asians, 3% in multiethnic scans, and less than 1% in African and Latin American populations. These percentages closely mirror the distribution of samples included in the discovery phase of cancer GWAS to date (84% European, 11% East Asian, 4% African and 1% Latin American ancestry). GWAS in non-European populations have provided insight into ancestry-specific variation in cancer and have pointed to regions of susceptibility that are of particular importance in certain populations. Uncovering and characterizing cancer risk loci in diverse populations is critical for understanding underlying biological mechanisms and for the future development of genetic risk prediction models in non-European ancestry populations. New GWAS and continued collaborations will be required to eliminate population inequalities in the number of studies, sample sizes, and variant content on GWAS arrays, and to better align genetic research in cancer to the racial/ethnic distribution of the global population.
Endocervical gland atypia secondary to Arias-Stella change

Arias-Stella change of the endocervix is relatively common if a systematic search can be made. However, the change has rarely been described in cervical/endocervical biopsy material. Five additional biopsy cases of the Arias-Stella change of the endocervix are documented, briefly discussed, and compared with other endocervical gland abnormalities. The Arias-Stella change of the endocervix is important to recognize because of its atypical appearance that, in this location, can be mistaken for premalignant, malignant, or other glandular abnormalities, especially if the pathologist is not aware of the patient's pregnancy.
Estimating Vessel Efficiency Using a Bootstrapped Data Envelopment Analysis Model

Technical efficiency, which measures how well a firm transforms inputs into outputs, gives fishery managers important information concerning the economic status of the fishing fleet and how regulations may be impacting vessel profitability. Data envelopment analysis (DEA), and the stochastic production frontier (SPF) have emerged as preferred methods to estimate efficiency in fisheries. Although each of the approaches has strengths and weaknesses, DEA has often been criticized because it is "deterministic" and fails to account for noise in the data. This paper presents a method for examining the underlying statistical structure of DEA models using bootstrap methods and readily available software. The approach is then applied to a case study of the U.S. mid-Atlantic sea scallop dredge fleet. Results show that the 95% confidence interval for technically efficient output is well above the maximum sustained yield (MSY) level of output.
Quantitative analysis of skin color from melanin content of superficial skin cells.

The color of human skin is determined by many factors. Blood supply, epidermal thickness, and pigments, both intrinsic and extrinsic, are responsible for the many variations we see. An important factor is the amount of the intrinsic pigment melanin, which absorbs and scatters ultraviolet radiation. In recent studies of the morphology of surface skin cells and their melanin content, we noticed a clear correlation between gross skin color and the average number of melanin granules per cell. This suggested that a quantitative analysis of melanin granules in skin cells from microscopic skin specimens, such as those present on clothing, could help to determine the skin color of the individual from which the cells came. This paper describes the methods of cell collection and staining followed and summarizes the results of the quantitative studies.
Swarm Intelligence for Collective Robotic Search

This chapter presents three strategies for the navigation of a swarm of robots for a target search application in a hazardous environment. The strategies explored include greedy search and two computational intelligence techniques—particle swarm optimization and fuzzy logic. Results for the collective search are presented for simulated environments containing single and multiple targets, with and without obstacles. The proposed navigation strategies can be further developed and applied to real-world applications such as aiding in disaster recovery, detection of hazardous materials, and many other high-risk tasks.
Long-term Effects of a Health Literacy Curriculum for Family Medicine Residents.

Introduction Improving education about health literacy for health care professionals has been recommended, and many US family medicine residency programs have developed such curricula. Few studies have evaluated the effectiveness of health literacy curricula for health care professionals. This pilot study aimed to determine whether a longitudinal health literacy curriculum for family medicine residents could achieve long-term sustained improvements in health literacy knowledge and clear communication practices. Methods Self-reported pre- and postassessments were conducted for a series of four health literacy didactic and experiential trainings over 11 months with a cohort of 12 first-year family medicine residents (study adequately powered for cohort of 10 or more). Results Five out of five health literacy knowledge items showed sustained significant improvement immediately after the initial didactic training. Two out of eight clear communication behaviors (eliciting patients' questions through an open-ended approach, and using a teach-back method to check for patients' understanding) showed sustained significant improvements in the 11-month follow-up period. The remaining six behaviors demonstrated a saw-tooth pattern, wherein each training session produced improvements in planned behaviors, which were, however, not maintained at subsequent follow-up assessments. Conclusions These data suggest that residents learned the cognitive material related to health literacy and clear communication easily, but had difficulty integrating many trained skills into clinical practice, despite the use of experiential learning techniques. Future studies should use an observational design to assess clear communication behaviors, and should include assessment of potential barriers to implementing clear communication skills in clinical practice.
Morphology and Immunophenotype of Chronic Lymphocytic Leukemia

Chronic lymphocytic leukemia (CLL) is an indolent mature B-cell lymphoproliferative disorder that often presents with bone marrow and peripheral blood involvement. Lymphadenopathy and proliferation in extramedullary tissues are often seen. The key to the precise diagnosis of CLL begins with assessment of the cytomorphology of the neoplastic cells, often from peripheral blood, but also the architectural patterns of involvement from tissue sections in bone marrow and lymph node biopsies. Although not 100% sensitive and specific, these morphologic features are strong clues in the broad differential diagnosis. Immunophenotyping complements and aids the morphologic impressions. Although often an indolent disease, some patients tend to have progressive disease and an aggressive clinical course. Staining for CD38 and 70 kD zeta-associated protein (ZAP-70) helps to prognosticate the patient’s disease and predict the tumor’s mutational status for the immunoglobulin heavy-chain, variable region (IGHV). Since defining the disease in the mid-nineteenth century, the workup of CLL now combines multiple disciplines, from basic characterization of morphology to immunophenotyping, and now molecular genetics that all aid in arriving at a precise diagnosis and help to choose the proper therapies for affected patients. In this section, the morphology and immunophenotype of CLL are discussed, with special emphasis on differential diagnosis and transformation (Richter syndrome). The issue of monoclonal B-cell lymphocytosis is also addressed, the criteria and description of which have recently been modified in the new 2016 WHO revision.
π-Choreography in aromatic ammonium formate solids

π-Interactions are a crucial factor in how aromatic ring systems are arranged and organized in the solid state. While these interactions are typically referred to as “π–π stacking interactions”, in reality, π–π stacking (direct overlap of rings) is a special case of interaction that is relatively uncommon, and is reserved for specifically tuned rings, typically those polarized by their substituents. More typically, a variety of other interactions involving the π-system of the aromatic rings exist in the solid state. These include the common offset (or “slipped”) π-interaction (really C–H⋯π) and C–H⋯π T-shaped arrangements. We have chosen an experimental approach to determine the likelihood of encountering π-interactions in two sets of layered salts. In both cases, benzylamines are used for the cations; however, the anion in one case is formate, and in the other is the mono-anion of pyrazoledicarboxylic acid (HPzDCA). To investigate and analyze the π-interactions found in each case, we report on eight new benzylammonium formate lamellar structures. These weak interactions are then compared to similar structures found in the Cambridge Structural Database, and to the HPzDCA case. This represents an analysis of the natural organization and directing of molecules containing aryl moieties when given the chance to self-assemble.
SEX IN UTOPIA: THE EVOLUTIONARY HEDONISM OF GRANT ALLEN AND OSCAR WILDE

In his provocative polemic “The New Hedonism,” Grant Allen mounts a passionate defense of fin-de-siecle aestheticism by proposing a modern ethic – the titular “new hedonism,” which he borrows from Oscar Wilde's novel The Picture of Dorian Gray (1890, rev. 1891) – that fully synthesizes aestheticism's insights with up-to-date scientific knowledge. At first glance, Allen seems an unexpected ally for Wilde, in part because few literary historians have explored the link between the two contemporaries. Many modern-day scholars of Allen's work (including Peter Morton, Bernard Lightman, William Greenslade, and Terence Rodgers) have tended to focus on his popular science writing, his elaborations on Herbert Spencer's evolutionary theories, and his controversial “New Woman” novels The Woman Who Did (1895) and The Type-Writer Girl (1897). Those who do connect Allen and Wilde, such as Nick Freeman, often draw the relationship into focus through the two writers’ shared interest in libertarian socialism rather than their overlapping philosophical and aesthetic concerns (111–28). Yet, as we can begin to see in the epigraphs, the association that Allen made between evolutionary progress and the “beautifying of life” echoes one of the most significant claims of Wilde's earlier, dialogic essay, “The Critic as Artist.” “Aesthetics,” Wilde's speaker, Gilbert, enthuses, “like sexual selection, make life lovely and wonderful, fill it with new forms, and give it progress, and variety and change” (“The Critic as Artist” 204). Allen's survey of human evolutionary history reminds him, too, that our cultural and artistic achievements are all that lift us “above the beasts that perish” (382). For both writers, then, aestheticism's commitment to beauty, “self-development,” and the emancipated pursuit of pleasure entails potentially sweeping consequences for the future evolution of humankind. Allen's vocal support for Wilde – which Allen expressed privately in letters as well as publicly in his 1891 article “The Celt in English Art” – was not simply a convenient political alliance, but an integral part of Allen's complete program for sociocultural improvement.
Beamforming P-band synthetic aperture radar for planetary applications

The Space Exploration Synthetic Aperture Radar (SESAR) is an advanced P-band beamforming radar instrument concept to enable a new class of observations suitable to meet multiple Decadal Survey science goals for planetary exploration. The radar is capable of providing unprecedented surface and near-subsurface measurements at full polarimetry and fine (meter scale) resolution, and achieves beam agility through programmable waveform generation and digital beamforming. The radar's highly flexible modular architecture employs a novel low power, lightweight design approach to meet stringent planetary instrument requirements, all while minimizing cost and development time.
Synthetic peptide-based activators of the proteasome

The development of small molecule peptide-based activators of the 20S proteasome or multicatalytic proteinase complex was initiated. The enhancement of antigen presentation by transfection of the protein activator PA28α into a mouse fibroblast cell line [10] supports the potential use of small molecule activators in stimulating the immune response. Four classes of peptide-based activators were synthesized, i.e. peptidyl alcohols, esters, p-nitroanilides and nitriles. These compounds markedly and reversibly stimulated the hydrolysis of suc-LLVY-MCA, Z-LLE-NA and Z-GPALG-p-aminobenzoate as well as hydrolysis of the decapeptide angiotensin I. Stimulation was due to a decrease in the K_ and increase in the Vmax of the substrate. In general, the EC50 for activation ranged from 50–150 mM and maximal stimulation varied from 3 to 15 fold depending on the activity measured. Z-IE(O-tBu)AL-p-nitroanilide, a proteasome substrate, markedly stimulated the hydrolysis of Z-GPALG-pAB by binding to a saturable high affinity site distinct from its binding site as substrate. Since all effective activators contain hydrophobic groups in positions P1-P5, low aqueous solubility is a limitation of these compounds. Competition experiments suggest that these activators bind to the same site as PA28.
Bacterial Type I Signal Peptidases

Publisher Summary This chapter discusses the type I bacterial signal peptidases, enzymes that catalyze cleavage of secretory signal peptides from proteins exported from the cytoplasm. Escherichia coli type I signal peptidase is the best characterized bacterial signal peptidase. The E. coli enzyme was the first signal peptidase to be cloned and characterized biochemically. More than 25 bacterial signal peptidase gene sequences are currently known. Type I signal peptidases are membrane-bound enzymes anchored in the cytoplasmic membrane of bacterial cells via one or more membrane anchors. E. coli leader peptidase is a single-chain protein with 324 amino acids anchored in the cytoplasmic membrane by two membrane anchors such that the active site domain is positioned in the periplasm. The chapter discusses that bacterial signal peptidases are resistant to inhibition by the usual reagents that inactivate the typical mechanistic classes of proteolytic enzymes. A number of pharmaceutical research teams have attempted to develop specific inhibitors of signal peptidase but apparently none has successfully identified a class of compound that could lead to full drug development.
X-Ray Spectral Measurement and Interpretation

Chemical analysis in the scanning electron microscope and electron microprobe is performed by measuring the energy and intensity distribution of the x-ray signal generated by a focused electron beam. The subject of x-ray production has already been introduced in the chapter on electron beam-specimen interactions (Chapter III), which describes the mechanisms for both characteristic and continuum x-ray production. This chapter is concerned with the methods for detecting and measuring these signals as well as converting them into a useful form for qualitative and quantitative analysis.
Corporate versus Community Power: A Santa Barbara Story

Fifty years ago, a massive oil well blowout and subsequent oil spill triggered community resistance to oil company operations in Santa Barbara county and its surrounding waters. The county has had surprising success in regulating and reducing oil development. That success is due to the combined effectds of grassroots mobilization, longterm organization, and the availability of state agencies and laws that legitimize community participation in corporarte development approvals. Despite Santa Barbara's relative affluence, its ongoing battle with the oil industry may be useful for formulating a theory of community empowerment globally.
Completeness, Finite Dimensionality, Differentiability

The first chapter treats questions concerning the foundations of the theory which were either not asked in G or left open.
Lipid Inclusions in Cardiac Myocytes - A Rare Case of Cardiolipotoxicity

Introduction The heart oxidizes fatty acids for its energy production. However, excessive accumulation of lipids due to various processes such as obesity, diabetes, heart failure (HF), myocardial ischemia, or infarction can result in damage to the heart tissue, also known as cardiolipotoxicity. Case A 69-year-old gentleman with a history of non-ischemic cardiomyopathy, right ventricle failure, permanent atrial fibrillation, ventricular tachycardia and cardiac cirrhosis presented to the hospital with exertional dyspnea, orthopnea, and decreased functional capacity. Physical exam was pertinent for elevated jugular venous distension, bibasilar rales, and bilateral pitting pedal edema. Laboratory findings were significant for brain type natriuretic peptide 1641 pg/ml, hemoglobin A1c 6.1%, total cholesterol 79 mg/dl, triglyceride 84 mg/dl, low density lipoprotein (LDL) 53 mg/dl, and high density lipoprotein (HDL) 9 mg/dl. Chest x-ray demonstrated mild pulmonary vascular congestion. Electrocardiogram showed atrial fibrillation and right bundle branch block. Transthoracic echocardiogram showed normal left ventricular systolic function with ejection fraction of 55%, severely dilated right ventricle with severely reduced systolic function and markedly dilated right and left atrium. Right heart catheterization showed findings consistent with mild pulmonary hypertension from diastolic HF and severe tricuspid regurgitation. Endomyocardial biopsy showed intracellular accumulation of significant amorphous material in most cardiac myocytes. Electron microscopy revealed fat lobules and inclusion bodies within the myocytes, consistent with cardiolipotoxicity (figure 1). Guideline directed medical management of HF was initiated and patient was subsequently discharged home. Discussion Due to various stressors such as HF, myocardial ischemia, infarction or atrophy, there is increased expression of genes involved in glucose metabolism rather than fatty acid oxidation. This leads to increased accumulation of lipids in the failing myocardium, thereby leading to cardiolipotoxicity. Increased lipid accumulation causes cardiac steatosis thereby leading to ER dysfunction, contractile dysfunction, and cell death. Our case describes a distinct metabolic phenotype of myocardial dysfunction for which no definite cause or treatment has been identified. Further research is required to advance our knowledge on cardiac metabolism in normal myocardium as well as in patients with HF, which could result in development of novel therapeutic interventions and strategies in these patients.
Correlation between hemolytic profile and phylotype of Cutibacterium acnes (formerly Propionibacterium acnes) and orthopedic implant infection.

IntroductionCutibacterium acnes is a recognized culprit for implant-associated infections, but positive cultures do not always indicate clinically relevant infection. Studies have shown a correlati...
Diel and circadian rhythms of locomotor activity in male Parasteatoda tepidariorum (Araneae: Theridiidae)

Despite recent interest, there still is relatively little known about the ecology and physiology of diel and circadian rhythms in spiders. However, previous work on spiders suggests that there is a striking amount of variation in circadian period both among, and within, species, when compared to model organisms. Whereas previous studies of behavioral rhythms in spiders focused on females, here we describe the diel and circadian patterns of locomotor activity in male Parasteatoda tepidariorum (C. L. Koch, 1841) (Theridiidae). We found that the males showed mostly nocturnal activity under a light:dark cycle, with activity peaking very early after lights off and steadily declining to near zero just prior to lights on. Under constant darkness most individuals showed significant circadian rhythmicity with a mean free-running period of about 21.2 h. Though not the shortest average free-running period described for spiders, being so out of resonance with the 24 h solar day strains conventional circadian rhythm theory. Our data also suggest that the phase angle of entrainment for locomotor activity is in the mid-to-late photophase, but that activity may be masked by light. Of particular note is that both the diel and circadian activity patterns reported here for male P. tepidariorum are similar to those reported elsewhere for females of the species. This study deepens our understanding of the nature and variation in circadian rhythm in spiders and builds a case for further developing spiders as a model system for research integrating the fields of chronobiology and ecology.
Learning from Gamettes: Imitating Human Behavior in Supply Chain Decisions

Gamettes are playful tools for agent-based participatory simulation and have shown to be valid for collecting rich behavioral data from human decision-makers. However, there is still a question that how such data can be used to create or update agent-based and behavioral models. In this paper, we evaluate and compare the performance of different methods for imitating human behavior. We use extracted data from gamettes in an empirical study on supply chain decisions, and compare the performance of a nonlinear regression model with two imitation learning algorithms. Our results demonstrate that each method is capable of modeling and thus predicting human behavior by considering multiple trajectories from different players.
Knowledge Maps: Building Conceptual CSS Knowledge Through Comparison

Many CSS tutorials exist online, yet novice web developers struggle to learn and apply professional CSS techniques. In this paper, we introduce Knowledge Maps (KM), a platform that guides novice developers to understand and compare professional web examples in order to learn and apply each example's professional techniques. By comparing professional techniques, learners are able to identify the tradeoffs and use cases associated with each technique. Knowledge Maps (KM) introduces three process management mechanisms to help learners understand examples: highlighted CSS properties, interactive CSS properties, and guided reflection prompts. In a user study where 9 users interacted with the Knowledge Maps (KM) platform on two examples using CSS grid layout, learners were able to understand the pros and cons between the CSS grid layout technique used in each example. Learners also demonstrated that they could apply their understanding to new use cases.
Predictive Preoperative Characteristics For Right Ventricular Failure After Left Ventricle Assist Device Placement

Introduction The current literature reports a 10-40% occurrence rate of right ventricular (RV) failure after left ventricular assist device (LVAD) implantation. We assessed our institution's incidence of RV failure after LVAD implantation to determine specific predictive values for developing RV failure after LVAD implantation. Methods We conducted a retrospective analysis of patients who underwent LVAD implantation from 2013 to 2019 at a single academic hospital. RV failure was defined according to the INTERMACS definition, with elevated central venous pressure (CVP) documented by right atrial pressure > 16mmHg, and manifestations of elevated CVP including renal dysfunction, or elevated bilirubin. Based on the duration of inotropes, severity of RV failure was further risk stratified as mild ( 14 days). Preoperative demographic, hemodynamic, echocardiographic and laboratory characteristics were identified amongst each group. Using patients without RV failure as the control arm, comparisons were made with independent two sample t-tests and multivariate analysis. Results Between 2013 to 2019, there were a total of 136 LVAD implantations at our institution in which 22.1% were as bridge to transplant, and 77.9% as destination therapy. RV failure was diagnosed in 44.1% of patients, in which 14.7% were categorized as mild, 17.7% as moderate, and 11.8% as severe. Preoperative parameters that predicted RV failure after LVAD implantation included right atrial pressure (RAP) > 10mmHg (RR: 1.58, 95% CI: 1.08 to 2.32, p=0.0174), preoperative renal dysfunction with BUN > 20 mg/dL (RR: 2.22, 95% CI: 1.45 to 3.41, p=0.0003) or Cr > 1.3 mg/dL (RR: 1.83, 95% CI: 1.28 to 2.63, p = 0.001) and total bilirubin > 1.5mg/dL (RR: 1.73, 95% CI: 1.21 to 2.46, p=0.0025). Conclusions Postoperative RV failure is a common occurrence after LVAD implantation. We identified that patients with elevated CVP, renal dysfunction and elevated total bilirubin pre operatively are at higher risk for developing RV failure after LVAD, and these patients should have a low threshold for RV support at the time of LVAD surgery.
Refining Measurements of Power Absorbance in Newborns: Probe Fit and Intrasubject Variability.

OBJECTIVES Because unresolved debris in the ear canal or middle ear of newborns may produce high false positive rates on hearing screening tests, it has been suggested that an outer/middle ear measure can be included at the time of hearing screening. A potential measure is power absorbance (absorbance), which indicates the proportion of power in a broadband acoustic stimulus that is absorbed through the outer/middle ear. Although absorbance is sensitive to outer/middle dysfunction at birth, there is large variability that limits its accuracy. Acoustic leaks caused by poor probe fitting further exacerbate this issue. The objectives of this work were to: (1) develop criteria to indicate whether a change in absorbance occurs in association with probe fit; (2) describe the variability in absorbance due to poor fitting; and (3) evaluate test-retest variability with probe reinsertions, excluding poor fits. DESIGN An observational cross-sectional design was used to evaluate changes in absorbance due to probe fit and probe reinsertion. Repeated measurements were recorded in 50 newborns (98 ears) who passed TEOAE screenings and were -0.11 cycles and (2) absorbance-based criterion (250 to 1000 Hz) > 0.58. Poor-fit measurements introduced statistically significant increases in absorbance up to 0.1 for 1000 to 6000 Hz, and up to 0.4 for frequencies <1000 Hz. Reinsertion Δ were ≤0.02, and were significant for 500 to 5000 Hz. The SDs of absorbance probe-fit Δ were greatest and similar to overall absorbance SD in the low frequencies. Separately, the SDs of reinsertion Δ were also greatest and similar to low-frequency absorbance SD. CONCLUSIONS Poor probe fits introduced the greatest inflation in absorbance for frequencies < 500 Hz, and a smaller but significant inflation for higher frequencies, consistent with controlled experiments on acoustic leaks in adults. Importantly, inflation of absorbance in diagnostically sensitive 1000 to 2000 Hz may impact its clinical performance. Test-retest with probe reinsertion contributed significantly to absorbance variability, especially in the low frequencies, consistent with reports in adults, even though changes were smaller than those associated with poor probe fit. The results indicate that variability in absorbance was reduced by minimizing acoustic leaks. Pending further validation, the probe-fit criteria developed in this work can be recommended to ensure proper probe fit.
Perinatal Cultural Aspects of African Refugee Women Resettled in Greece: Providing Culturally-sensitive Midwifery Care.

Introduction African refugee women constitute a growing group of maternity service users in Greece. Being a refugee is considered a risk factor in itself for poorer maternal and neonatal health outcomes. These women additionally, are at high risk of perinatal complications, often due to misconceptions or absence of interpretation between providers and patients through different cultural concepts. Consequently, midwives may feel uncertainly experienced when provide perinatal care for a culturally diverse patient population. Aim The aim of the study was to investigate perinatal cultural aspects and practices of African refugee pregnant women in Greece, in order to increase cultural awareness and improve midwifery care in a culturally-sensitive way. Methods Forty-two (n=42) African pregnant women who lived in a "Reception and Identification Center" on a greek island named "Samos", were included in the study. Women were selected by "simple random sampling" and asked to complete anonymously, with assistance of interpreters, a questionnaire that was devised by the authors with open-ended and closed-ended questions. Results Women were aged between 19-38 years old. The 50% (n=21) of them were from the Democratic Republic of the Congo, 28.6% (n=12) from Ghana and 21.4% (n=9) from Cameroon. Major themes emerging from the data analysis were: presence of antenatal care in African countries, potentiality of abortions, complications in previous pregnancy, supplement receipt in previous pregnancy after healthcarers' consultation, decision of birth place, support of traditional birth attendants' during pregnancy and birth, consumption of culturally acceptable food during pregnancy and birth, culturally accepted disposal of placenta, postpartum ceremonies for the baby and newborn's navel care. Conclusion Increased understanding of the pluralistic African perinatal cultural aspects is essential. Inclusion of cultural insight and/or family members in decision making and implementation of training programmes culturally-oriented for midwives, can fulfil women's health, social needs and expectations.

Myoepithelioma of the ankle: A case report

Myoepitheliomas are rare benign and malignant neoplasms composed of spindled, ovoid, or plasmacytoid cells. These tumors have been reported to occur in salivary glands and cutaneous, subcutaneous, and deep soft tissues of the head and neck, upper and lower extremities lung, and breast. Surgical resection with clear margins is the standard of care for the treatment of both low-and high-grade neoplasms. A 55- year-old female with no significant past medical history presented to an urgent care center with left ankle pain after suffering an inversion ankle sprain. Radiographs of the left ankle were reviewed and were negative for any bony pathology. She continued to have pain, edema, and developed a localized soft tissue mass at the retromalleolar area. MRI showed a soft tissue tumor adjacent to the peroneal tendons. The mass was removed and pathology confirmed it as a myoepithelioma, which is a rare tumor of the lower extremity. Myoepitheliomas are most commonly found in the salivary glands and can have a benign or malignant characteristic. Other common locations include the limbs and trunk region and the lesion typically presents in young to middle aged adults. Recurrence of histologically benign tumors has been associated with a local recurrence of 20% and rarely metastasize. Gene rearrangement at the ESWR1 (22q12) location is seen in >90% of soft tissue sarcomas. In this case, FISH analysis did not reveal gene rearrangement at ESWR1 22q12. The clinical significance is unknown and does not rule out a malignancy or other genetic changes.
Biointegrated wireless battery free sensors and stimulators

Recent advances in materials and fabrication concepts for the creation of soft electronics coupled with miniaturization of wireless energy harvesting schemes enable the construction of high-performance electronic and optoelectronic systems with sizes, shapes and physical properties matched to biological systems. Applications range from continuous monitors for health diagnosis to minimally invasive exploratory tools for neuroscience. This talk introduces science and engineering aspects for the creation of soft devices with wireless power transfer and data communication capabilities and discusses application in minimally invasive exploratory neuromodulation tools and imperceptible body-worn sensing devices. Specifically, we present two new classes of devices for implantable and wearable biointegrated electronic devices. Firstly, we will introduce wireless, battery free and fully implantable neuromodulation tools that provide unparalleled capabilities to modulate the central nervous system. The tools enable new experimental paradigms in a range of complex environments and contexts that cannot be explored with conventional technologies. The devices feature miniaturized form factor and technologies that are rapidly scalable to enable broad dissemination while still maintaining compatibility with noninvasive imaging technologies such as computed tomography (CT) and magnetic resonance imaging (MRI). Specifically, we will highlight 1. Current advances in highly miniaturized wireless and battery free photometric recording devices that enable the study of neural dynamics in ethnologically relevant environments in young animal models unlocking new experimental paradigms to uncover the working principles of the developing brain. 2. Wireless battery-free and subdermally implantable optogenetic stimulation tools that enable: neural activation in freely flying birds; transcranial optogenetic stimulation in mice without cranial surgery; long range neural activation in ethologically relevant environments. Secondly, we will present a new class of wearable wireless, battery free, long range, personalized and multimodal sensors system. The first of its kind device architecture is shaped by physiology and enables uninterrupted 24 hour data streams with high fidelity over long periods of time. The devices feature highly personalized device geometries that solve prevalent problems of current adhesive based wearable devices while still retaining intimate contact.

The Impact of Natural Disasters on Migration Within Emerging Economies

Natural disasters have been shown to have a significant impact on migration, particularly among individuals who have the resources to move and the human capital potential to succeed after the move. This study expands on prior research by examining the impact of disasters on net-migration into high-growth emerging economies. After controlling for a series of macroeconomic factors, the findings show that the frequency of disasters more so than any other impact measure can influence migration decisions.
Choosing Performance-Based Outcome Measures of Daily Living Skills and Socialization for Clinical Trials in Autistic Children.

Importance Robust and psychometrically sound performance-based outcome measures are needed for clinical trials of occupational therapy interventions for children with autism. Objective To demonstrate a systematic approach for choosing psychometrically sound performance-based outcome measures of daily living skills and socialization for use in clinical trials of occupational therapy interventions for children with autism.

What This Article Adds: This project demonstrates use of a systematic process for choosing outcome measures for a planned clinical trial.
Model Predictive Control for Mobile Robots with Actively Reconfigurable Chassis

Actively reconfigurable chassis enable planetary mobile robots to access more varieties of terrain. While typical approaches for exploiting such mechanisms reply on feedback control, it is beneficial to consider actively controlled elements at planning time rather than during motion execution. In this paper we present an approach for extending work in model-predictive trajectory generation to actively reconfigurable chassis. The motion planner uses a kinematic motion model and a terrain shape model to determine sequences of actions that minimize a cost function over vehicle attitude by modifying the shape of the velocity, curvature, and chassis configuration profiles. Simulation and field results are presented demonstrating the benefits of this technique on a prototype mobile robot for lunar excavation.
High performance computing techniques for scaling image analysis workflows

Biomedical images are intrinsically complex with each domain and modality often requiring specialized knowledge to accurately render diagnosis and plan treatment. A general software framework that provides access to high-performance resources can make possible high-throughput investigations of micro-scale features as well as algorithm design, development and evaluation. In this paper we describe the requirements and challenges of supporting microscopy analyses of large datasets of high-resolution biomedical images. We present high-performance computing approaches for storage and retrieval of image data, image processing, and management of analysis results for additional explorations. Lastly, we describe issues surrounding the use of high performance computing for scaling image analysis workflows.
The Differing Effects of Alliance Governance Experience on Firm Capability Building

Firms employ different governance structures in interfirm relationships depending on the varying levels of contractual risks. However we know little about how such governance structures shape the path through which firms build capabilities. In this study I propose a theoretical model examining the different capability building processes of various governance structures guiding collaborative relationships. I categorize two types of capabilities that are fundamental in cooperative relationships: contract design capability and coordination capability. As firms accumulate collaborative experience from prior alliances, they build these capabilities along different trajectories. These learning paths are further moderated by technological diversity in partners' prior alliance experiences. This study contributes to the alliance research by proposing the learning processes embedded in governance structures of interfirm relationships, and connecting transaction cost economics with organizational learning theory and the resource-based view.
