Quantum information and computation for chemistry 2016

The NSF Workshop in Quantum Information and Computation for Chemistry assembled experts from directly quantum-oriented fields such as algorithms, chemistry, machine learning, optics, simulation, and metrology, as well as experts in related fields such as condensed matter physics, biochemistry, physical chemistry, inorganic and organic chemistry, and spectroscopy. The goal of the workshop was to summarize recent progress in research at the interface of quantum information science and chemistry as well as to discuss the promising research challenges and opportunities in the field. Furthermore, the workshop hoped to identify target areas where cross fertilization among these fields would result in the largest payoff for developments in theory, algorithms, and experimental techniques. The ideas can be broadly categorized in two distinct areas of research that obviously have interactions and are not separated cleanly. The first area is quantum information for chemistry, or how quantum information tools, both experimental and theoretical can aid in our understanding of a wide range of problems pertaining to chemistry. The second area is chemistry for quantum information, which aims to discuss the several aspects where research in the chemical sciences can aid progress in quantum information science and technology. The results of the workshop are summarized in this report.
“That’s My Face to the Whole Field!”: Graduate Students’ Professional Identity-Building through Twitter at a Writing Studies Conference

Abstract Twitter usage (“tweeting”) at academic conferences is quickly gaining prevalence. This fast-growing practice is an example of the complexity of academic discourse communities and how digital interactions aid scholars in building meaningful working relationships. Graduate students, in their position as “peripheral participants” in their academic disciplines (Lave & Wenger, 1991), have a unique perspective on the process of building their academic identities and relationships that will last a career. This qualitative interview study examines the perspectives of five Ph.D. students at universities across the United States who used Twitter at the academic conference Computers and Writing in May 2015. Building on previous studies on digital communication among academics (Hyland, 2012; Leon & Pigg, 2011; Li & Greenhow, 2015), this study reveals the behind-the-scenes perspectives of graduate students who used Twitter at this academic conference. Findings include a look into the intentionality these graduate students bring to their conference tweeting, explanations of their efforts to connect with others and build name- and face-recognition in the academic discourse community, and other useful insights into graduate students’ conference tweeting.

TODS special issues

The March 2004 issue of TODS should be in your mailbox (as well as available in cyberspace, at the ACM Digital Library) around the time you receive this issue of SIGMOD Record. This issue is a first, a special issue dedicated to extended versions of SIGMOD and PODS papers from the 2002 conference. This special issue opens the topic of invited papers from conferences, and indeed, the more general topic of journal versions of conference papers. A conference paper is the scholarly equivalent of fast food: quick to read (eat), sometimes healthy for you, and undoubtably convenient. The strict page limit (10–12 pages, depending on the conference) favors topics that can be introduced, developed, and evaluated in a short amount of space. One can read several conference papers, on a wide variety of topics, in the time that it takes to read one journal article. A journal paper is the equivalent of a three-course dinner. It is allowed space (in terms of page count) to more fully examine related work, develop algorithmic or theoretical refinements to the proposed approach, and perform a more thorough evaluation of the central idea of the paper. Some topics are perfect for a conference paper. The approach is simple and thus can be described fully in just a few pages, the applicability is routine, the related work minimal, and the requisite evaluation straightforward. Other topics are better suited for a journal paper: there may be a substantial prior literature that must be summarized and the positioning of the paper explained, the approach may be complex and require careful development, the evaluation may be quite involved, with many aspects to consider. In fact, some ideas require more space than even a journal article provides (as I have remarked in these pages three years ago1). The impetus for the last two books that I wrote was exactly that: I knew that to fully discuss my ideas and the rationale behind them, a single journal article, or even two or three related articles, would not be sufficient, but the several hundred pages afforded by a book-length monograph was perfect. Then there are those ideas that work well in both conference and journal form. The conference paper is a teaser, presenting just enough of the idea and its evaluation to be interesting and to get the idea out there. The journal paper then elaborates on the idea, expounding on exactly where and in what circumstances the idea applies, identifying exactly where the benefits reside and the magnitude of those benefits, and providing a full exposition of the idea, with all necessary detail. It is this last category of papers that program chairs of SIGMOD, PODS, EDBT, and ICDT are encouraged to nominate for invitation. These nominations are evaluated by the Editor-in-Chief and a relevant Associate Editor to select those conference papers with the most potential for extension, for invitation. The invitation emphasizes the TODS prior publication policy2, summarized here.
The Globesity Epidemic

Obesity is pervasive at international and national levels. Globally, 2.8 million adults die from obesity and this condition is considered the 5th leading cause of global mortality. According to the World Health Organization (Commission on ending childhood obesity: facts and figures on childhood obesity, 2017. Retrieved from http://www.who.int/end-childhood-obesity/facts/en/), one third of the population is obese. Worldwide obesity doubled over the past few decades and concomitantly, by 2014, approximately 1.9 billion people over the age of 18 were considered overweight. People who are overweight experience higher mortality compared to individuals who are underweight. In 2014, children under the age of five were impacted, with 5 million experiencing obesity or pronounced overweight. Given these statistics, this chapter examines the prevalence and causal factors for adult and childhood obesity in various countries.
Do All Positive Margins in Breast Cancer Patients Undergoing a Partial Mastectomy Need to Be Resected

Background Positive margins have been reported in 20% to 40% of patients undergoing a partial mastectomy, often resulting in re-excision. How often the re-excision yields additional cancer and whether there are predictors of residual disease remain unknown. Study Design Patients who had a positive margin (defined as tumor at ink for patients with invasive disease or within 1 mm for patients with ductal carcinoma in situ) in the SHAVE (A Randomized Controlled Trial of Routine Shave Margins Versus Standard Partial Mastectomy in Breast Cancer Patients) trial before randomization were evaluated to determine the rate of additional disease either in cavity shave margins or at re-excision. Details of the SHAVE trial can be found elsewhere. Results Of the 235 patients in the trial, 82 (34.9%) had a positive margin before randomization; 58 of these patients underwent either cavity shave margins excision or a re-excision of the positive margin(s). Twenty-one (36.2%) patients had residual disease. On bivariate analysis, residual disease was associated with younger patient age (median 51 vs 62 years; p = 0.007), and the presence of high-grade ductal carcinoma in situ (57.1% vs 31.3% for grade 2 and 0% for grade 1; p = 0.025). The following factors were not associated with further disease: patient race; ethnicity; BMI; volume of resection; number of positive margins; extent of ductal carcinoma in situ; and extent, grade, and histologic subtype of invasive cancer. On multivariate analysis, only patient age younger than 60 years remained a significant predictor of residual disease (odds ratio 3.920; 95% CI 1.081 to 14.220; p = 0.038). Conclusions Positive margins are associated with further disease in more than one-third of patients and, aside from young age, there are no predictors of this. These findings support continued re-excision of positive margins, particularly in patients younger than 60 years of age.
At all hospitals in the State of Iowa over a decade, the number of cases performed during weekends or holidays increased approximately proportionally to the total caseload.

Abstract Study objective We tested the hypothesis that over many years – a decade – hospitals' proportions of surgical cases that were performed on weekends and holidays remained stable. Design Retrospective cohort study. Setting Iowa Hospital Association data were from January 1, 2007, through June 30, 2017. The N = 42 hospitals included were those with at least 10 cases performed during holidays or weekends for each of the periods. Measurements The number of surgical cases performed at each hospital during each of the 21 half-year periods was considered the count of unique combinations of hospital, patient, and date with at least one major therapeutic procedure. Main results Absolute predictive errors in cases per weekend or holiday day were calculated using a proportional model and using a quadratic model for each hospital and half-year period. Pooling among hospitals, the sample mean absolute predictive errors were greater for the proportional model than for the quadratic model (P Conclusions For the anesthesia group caring for patients at a hospital over several years, weekend and holiday anesthesia caseload should be expected to increase approximately proportionately to changes during regular workdays. Average weekend workload can be benchmarked using hospitals' percentages of operating room cases performed on weekends and holidays.
DO Loop Transforming Tools

This chapter is an overview of three transformation tools recently contributed to the Toolpack/1 tool collection. The first tool unrolls outer DO loops, the second condenses sequences of inner DOs in unrolled outer DOs into single DO loops together with assignment statements, and the third combines sequences of assignment statements resulting from the action of the first two tools. Acting in concert with one another and with other Toolpack/1 tools, these tools transform certain classes of Fortran DO nests that typically occur in linear algebra software. The effect is to improve the performance of such software on vector machines by reducing the number of words transferred between memory and the vector registers. Emphasised in this chapter are features of the Toolpack tool-writing environment that are employed in writing such transformation tools.
Simulation of Energy Systems' Operation

Publisher Summary This chapter describes the simulation of energy systems operation. The main goal in effectively modeling energy power generation systems are reasonable execution times together with a general applicability to any power systems achieved by its modular structure. The MIP model is derived from the nonlinear dynamic process by discretization in time and piecewise linear approximation. The most important aspect to yield short execution times are submodels with a small number of integer variables summarized in special ordered sets if possible with a good approach in picturing the reality. The number of system elements to be modeled is more or less unlimited. The matrix generator produces the MPSX data input files out of the given data set of the power generation system, and its preassigned energy resources using the DP implementation of the MIP model. The matrix generator has a modular structure, and each module consists of an input and a checking subroutine, a printing subprogram to produce a review, and of one or more subroutines to generate the input files for the optimization program by applying the mathematical model.
Elevated serum estradiol associated with increased androstenedione-testosterone ratio in adolescent males with varicocele and gynecomastia.

Objective To investigate the testicular function in adolescents with pubertal gynecomastia associated with varicocele before and after varicocelectomy. Design and Patients We have studied six male adolescents 15 to 19 years of age with bilateral gynecomastia. They were selected among other adolescents with gynecomastia because of the presence of visible varicoceles. All of them had normal physical examination and secondary sexual characteristics. This was a prospective study of 3 months’ duration. All the patients that were included finished the study. Setting All the patients were evaluated in the Endocrine Clinic of Winthrop-University Hospital, a tertiary care unit. Interventions Serum testosterone (T), androstenedione (A), and estradiol (E 2 ) responses to the administration of human chorionic gonadotropin (hCG) 2,000 IU for 3 consecutive days before and 3 months after varicocelectomy were determined. Results Varicocelectomy did not cause any significant changes in the basal (pre-hCG) levels of the steroid. However, the increase in T levels achieved with hCG was significantly ( P 2 and A were significantly lower ( P 2 , 62 ± 12 pg/mL; A, 326 ng% ± 80 ng%) than before (E 2 , 106 ± 13 pg/mL; A, 580 ng% ± 95 ng%). Conclusion The reciprocal effect on the levels of T and its immediate precursor, A, suggests an impairment of the 17-ketoreductase enzyme activity. The increased levels of E 2 after hCG and its normalization after varicocelectomy suggests that varicoceles may play a pathogenetic role in the development of gynecomastia.
The Story of Madrigal v. Quilligan: Coerced Sterilization of Mexican-American Women

This essay tells the story of Madrigal v. Quilligan, an unpublished decision from a California federal district court refusing to remedy sterilization abuse in the early 1970s. After a whistleblower leaked evidence of rampant sterilization abuse at the Los Angeles County USC Medical Center, ten women (the Madrigal Ten) filed a lawsuit alleging that medical personnel systematically coerced Mexican-American women into submitting to sterilization. The case dramatically altered public consciousness and public policy on coerced sterilization. Despite their loss in the damages phase of the litigation, the Madrigal Ten served as the catalyst for California’s strengthened regulations for ensuring voluntary consent to sterilization. In addition, the Madrigal litigation also inspired the anti-sterilization abuse movement in California and helped to shape Chicana feminism in the 1970s. The case galvanized Chicana feminist activism in ways that highlighted tensions between mainstream white feminists and women of color. The Chicana activists working on the Madrigal matter used multiple strategies to achieve their policy goals. They relied not only on the litigation of the case itself, but also lobbied for legislative reform and engaged in public education, including through widespread media attention. The activists brought the still nascent framework of reproductive justice to the forefront, incorporating concerns about discrimination along intersectional lines of gender, race, poverty, and immigration status — all issues at play in the Madrigal case. The essay also explores how the story of Madrigal v. Quilligan still resonates today. The threat of sterilization abuse continues to loom for vulnerable populations, particularly poor women and women of color.
Iodine speciation in cementitious environments

Abstract Iodine-129 is a key risk driver in most low-level waste cementitious waste repositories. Objectives of this study were to determine iodine speciation in cementitious materials with slag (Grout+slag) and without slag (Grout–slag) and its impact on iodine immobilization. Irrespective of which iodine species was amended to the aqueous phase, there were no significant differences in uptake-Kd values (∼3 L/kg). However, when the various iodine species were hydrated with the grout, the release-Kd values (6.1–121.8 L/kg) were significantly greater than the uptake-Kd values, and the amended iodine speciation (I− ≪ org-I ≤ IO3−) and grout formulation (Grout–slag
Dynamics of spreading on ultra-hydrophobic surfaces

Despite the extensive variety of applications for ultra-hydrophobic surfaces in industry, technology, and biology, due to their wetting characteristics, there has not been considerable attention in the area of dynamics of wetting on ultra-hydrophobic surfaces. In this research, the experimental investigations have been done by applying forced spreading of several polyethylene-glycol/water mixtures in different weight ratios on Teflon plates and ultra-hydrophobic sprayed glass substrates. Hydrodynamics theory and molecular-kinetic theory have been applied to investigate the dynamics of wetting on these substrates. It has been found that the dynamics of receding motion of liquid contact line on ultra-hydrophobic surfaces could be described perfectly with the molecular-kinetic theory. In the case of advancing motion on an ultra-hydrophobic surface, dynamic contact angle is independent of liquid contact line velocity. The advancing and receding motions of liquid contact line on smooth Teflon plates followed molecular-kinetic theory.
Context-adaptive recursive-filtering-based intra prediction in video coding

Conventional intra prediction modes in image and video coding generate an estimation of a target block by copying or projecting its causal neighboring pixels along certain angles. Such simple directional model does not work well for complex image structures. A set of context-adaptive intra prediction modes based on recursive filtering is proposed in this paper. The prediction of a block is generated by applying linear filtering over certain previously reconstructed or predicted pixels in the causal neighborhood of each pixel recursively. The filter coefficients are estimated with least squares optimization using previously reconstructed pixels in the above and/or left regions of the current block. The configurations for the filters such as filter taps, position of reference pixels, as well as the location and shape of the training regions are all flexible, making the proposed prediction modes highly adaptive to local image texture contexts. A data-driven approach is used to select the optimal subset of all the possible filter configurations while retaining as much coding gains as possible. The proposed approach is tested on the state-of-the-art AV1 video coding standard. AV1 supports sophisticated intra prediction tools such as recursive filtering, quadratic interpolation filtering, intra block-copy, and the palette mode. Experimental results show that the context-adaptive recursive-filtering-based intra prediction modes can achieve significant improvement in compression efficiency.
Trends in Magnesium Intake among Hispanic Adults, the National Health and Nutrition Examination Survey (NHANES) 1999-2014.

This study aimed at examining trends in magnesium intake among U.S. Hispanic adults stratified by gender, Hispanic origins, age, and poverty income ratio (PIR) level. Data on 9304 Hispanic adults aged ≥20 years from eight National Health and Nutrition Examination Survey (NHANES) cycles (1999–2014) were included in this study. For each cycle, survey-weighted mean dietary and total magnesium intakes were estimated. The prevalence of dietary and total magnesium intake below the Recommended Dietary Allowance (RDA) was further estimated stratified by gender and age groups. Linear regression was used to test trend. Over the survey cycles, both dietary and total magnesium intakes were significantly increased among Hispanic adults. In the study period, magnesium intake tended to be lower in females, adults in other Hispanic-origin group, those aged ≥65 years old, and those with a PIR <1.0. The prevalence of magnesium intake inadequacy decreased among Hispanic adults; however, more than 70% of Hispanic males and females continued to have magnesium intake below the RDA in 2013–2014. From 1999/2000 to 2013/2014, despite several improvements in magnesium intake having been identified, additional findings showed insufficient intake in Hispanic males and females, suggesting the need to improve magnesium intake through diet and dietary supplementation for U.S. Hispanics.
Experiential Teaching Paradigms: Adapting the Medical Education Literature to Academic Pathology Practice:

The medical education literature has presented many experiential teaching paradigms to help faculty teach more effectively in busy clinical settings. Three prominent teaching models are The Aunt Minnie model, the SNAPPS model, and the One-Minute Preceptor. Teaching paradigms can help faculty to develop into effective teachers. Each of these models can be adapted to a busy academic pathology practice. The Aunt Minnie model is effective in cases with high pattern recognition, such as repetitive trays of biopsies. The SNAPPS model is learner directed and is easily adapted for an advanced learner with complex cases requiring ancillary testing. The One-Minute Preceptor method is effective for teachers with groups of learners, such as multiheaded scope sessions.
A mesopelagic ctenophore representing a new family, with notes on family-level taxonomy in Ctenophora: Vampyroctena delmarvensis gen. nov. sp. nov. (Vampyroctenidae, fam. nov.)

The stunning diversity of midwater ctenophores is well-known to veterans of oceanographic cruises and ROV operations, but many species lack formal descriptions, leading to taxonomic confusion and a systematic underestimation of the biodiversity of the mesopelagic zone. Here, we present a description of a novel genus and species of one such ctenophore, Vampyroctena delmarvensis gen. nov. sp. nov. This cydippid ctenophore, the sole described representative of Vampyroctenidae fam. nov. (Class Tentaculata, Order Cydippida), was collected in mesopelagic waters off the coast of Delaware in the northwest Atlantic Ocean and has a characteristic bright red mesoglea, large paragastric diverticulae, deep red macrocilia, and a darkly pigmented gut. A molecular phylogenetic analysis of Ctenophora based on transcriptomic data places V. delmarvensis gen. nov. sp. nov. as the closest known relative to Euplokamis dunlapae Mills, 1987 (Euplokamididae), in a clade that is sister to all other ctenophore lineages.
Relationship of Hospital Star Ratings to Race, Education, and Community Income.

Introduction The Centers for Medicare & Medicaid Services (CMS) publishes hospital quality ratings to provide more transparent and useable quality information to patients and stakeholders. However, there is a gap in the literature regarding the geographic distribution of the hospitals with higher star ratings. In this paper, we focus on the associations between star ratings and community characteristics, including racial/ethnic mix, household income, educational attainment, and regional difference. Methods A retrospective study and cross-sectional logistic and multinomial logistic regression analyses. Results According to the multivariate regression results, hospitals in areas with lower income, lower educational attainment, and higher minority population shares have lower quality ratings (lower income: odds ratio [OR] 0.67; 95% CI, 0.49-0.91; lower education: OR 0.66; 95% CI, 0.51-0.85; higher minority: OR 0.52; 95% CI, 0.40-0.69). Compared with hospitals in the Midwest, hospitals in Northeast, South, and West regions have lower quality ratings (Northeast: OR 0.37; 95% CI, 0.25-0.56; South: OR 0.68; 95% CI, 0.51-0.91; West: OR 0.69; 95% CI, 0.49-0.97). Discussion and conclusion Overall, our results show that hospitals with higher star ratings are less likely to be located in communities with higher minority populations, lower income, and lower levels of educational attainment. Findings contribute to the discussion of integrating social factors in hospital quality star rating calculation methodologies.
Swampland cobordism conjecture and non-Abelian duality groups

We study the cobordism conjecture of McNamara and Vafa which asserts that the bordism group of quantum gravity is trivial. In the context of type IIB string theory compactified on a circle, this predicts the presence of D7-branes. On the other hand, the non-Abelian structure of the IIB duality group $SL(2,\mathbb{Z})$ implies the existence of additional $[p,q]$ 7-branes. We find that this additional information is instead captured by the space of closed paths on the moduli space of elliptic curves parameterizing distinct values of the type IIB axio-dilaton. This description allows to recover the full structure of non-Abelian braid statistics for 7-branes. Combining the cobordism conjecture with an earlier Swampland conjecture by Ooguri and Vafa, we argue that only certain congruence subgroups $\mathrm{\ensuremath{\Gamma}}\ensuremath{\subset}SL(2,\mathbb{Z})$ specifying genus zero modular curves can appear in 8D F-theory vacua. This leads to a successful prediction for the allowed Mordell--Weil torsion groups for 8D F-theory vacua.

Pediatric Pain Assessment in the Intensive Care Unit: An Evidence-Based Algorithm.

Abstract Background Conducting an adequate pain assessment in the Pediatric Intensive Care Unit (PICU) is multifactorial and complex due to the diversity of the population. It is critical that validated pain assessment methods are used appropriately and consistently to aid in evaluation of pain and pain management interventions. Purpose The aim of this evidence-based practice project was to improve pain assessment practices in the PICU through a decision-support algorithm. Design & Methods The Iowa Model-Revised was used to guide the development and implementation of an evidence-based decision algorithm. Pre- and postdata were collected via surveys (nursing knowledge and confidence) and documentation audits (nursing pain assessments). Various implementation strategies were used to facilitate the integration and sustainability of the algorithm in practice. Results The majority of survey items showed an increase in nursing knowledge and confidence. Audits of pain assessment documentation displayed an increase in appropriate pain assessment documentation related to a child's communicative ability. However, there is a need for reinfusion related to the documentation of sedation assessments. Conclusions The use of an algorithm supported the ability of PICU nurses to critically consider and choose the pain assessment method most appropriate for the patient's condition. The algorithm promotes nursing clinical judgement, prioritizes pain management, and includes patients receiving sedation. The algorithm supports a comprehensive pain assessment in a difficult pediatric patient population. Future research is needed to strengthen and standardize the usage of terms “assume pain present” and “assume pain managed,” and to also improve the overall feasibility and effectiveness of the algorithm.
Secrecy Performance in Ultra-Dense Networks with Multiple Associations

Network densification is a promising approach to support the ever-increasing required capacity in cellular networks. Besides, securing the gigantic amount of sensitive data transferred within the network has become a critical issue. Ultra-Dense Networks (UDNs) with a massive number of deployed Small Cells (SCs) constitute the new trait of network densification. Exploiting this massive number of small cells and their proximity to served users, we can enhance the achievable secrecy rate in the network. In this paper, we study Physical Layer Security (PLS) in a multiple-association scenario where each user is served simultaneously by a group of the M closest SCs. This approach helps to mitigate the limitations in the backhaul link capacities of the SCs. Besides, it provides spatial diversity for the users when their data traffic is split into different paths which enhances secrecy performance. Using tools from stochastic geometry, we provide a lower bound analytical expression for the average secrecy rate per user. The obtained results via both analysis and system-level simulations show the significant gain in secrecy performance that can be attained from the proposed multiple associations scheme.

Amendment thresholds and voting rules in debt contracts

We study the voting rules to modify, amend, and renegotiate syndicated loan contracts. We base our hypotheses on a model that shows how amendment thresholds can mitigate agency conflicts within the lending syndicate. Consistent with our model predictions, we find that voting rules are more lenient when the lead lender has prior syndicate relationships with non-lead lenders and when the borrower has high default risk. We also find that voting rules are more stringent when the lead lender has a prior underwriting relationship with the borrower, which may indicate potential conflicts of interest between the lead and non-lead lenders. Lastly, we show that loan amendment thresholds are negatively associated with future loan amendments, and positively associated with capital covenants.
Quasi-Dense Motion Stereo for 3D View Morphing

This paper presents a novel approach to image based rendering . The problem of constructing a new view based on a set of snapshots taken from known locations is formulated as a morphing task . Appropriate morphing functions are constructed by considering a set of feature points in the scene which correspond to intensity discontinuities in the original pictures. The locations of these features in the scene are recovered automatically from the image data by employing epipolar plane image analysis. One of the main advantages of the proposed method is that it correctly reproduces parallax in the most perceptually salient regions of the image, the areas corresponding to intensity edges. Results obtained by applying the proposed technique to actual image data sets are presented.
Gamma-Ray Strength Functions for Medium Weight Nuclei

A series of (n,γ) statistical model cross-section calculations, for incident neutron energies of 1 keV to 3 MeV, were made for 12 target nuclei from 75As to 103Rh. The calculations were adjusted to fit the available experimental data, and values for 2πΓγ/D at the neutron separation energy were extracted. From these, effective El strength functions were obtained, assuming only dipole transitions, an Ml contribution of about 15%, and the Brink-Axel energy dependence for the El transitions. Systematics were also developed to estimate the El strength function based on the parameterization of the giant dipole width in terms of the nuclear deformation, β2. When compared with these estimates, the strength functions extracted from the capture data seem to exhaust the dipole sum rule to the extent inferred from total integrated photoneutron data. Two exceptions to this statement are the compound nuclei 76As and 104Rh.
Amino Acids, Peptides, and Proteins

The amino acids are the building blocks of peptides and proteins. They occur both free and combined in structural proteins (keratin, etc.), and enzymes, the catalysts associated with life’s processes. About ten of them are essential human nutrients. Receptors for taste and olfaction are also believed to be proteins, and amino acids, peptides, and proteins have varied tastes.
A Follow-Up Study of Traumatized Children.

This study compared 17 abused children with 17 children who had been in accidents, matched for age, race, sex, and socioeconomic status, eight years after all had been studied as infants. Each traumatized group was also compared with a matched untraumatized group with no known history of abuse or infantile accident. The majority of all children were lower-class. Hypotheses were that the abused children would fall below the nonabused in health history and physical development, intellectual functioning, language, and self-concept; and that the abused children would score higher in impulsivity and aggression. Clinical assessments revealed few group differences. The surprising finding was the extent of various problems across the entire sample. Seventy percent of the children had speech problems; over 50% showed some degree of disturbance; and 39% were achieving poorly in school. However, these disabilities were distributed randomly among abuse, accident, and comparison children. Most of the children appeared sad and fearful of personal attack by adults or other children. Many mothers' reports indicated that the families, whether abuse, accident, or comparison, experienced constant violence, both environmental and personal. It was concluded that the effects on child development of lower-class membership may be as powerful as abuse. Language: en
Charge-transfer acceptors : Indanetrione

Abstract A hypothesis for the design of organic charge-transfer acceptors is proposed and tested. The acceptor structure criteria include: (1) electron withdrawing power of substituents, (2) the number and location of substituents, and (3) the conjugated system to which groups are attached. This hypothesis, applied to modification of the substituents in phthalic anhydride, leads to the prediction that indanetrione should be an effective acceptor with an electron affinity between 0.7 and 1.2 eV. Indanetrione was prepared by thermal dehydration of ninhydrin. π-Complexes of indanetrione were measured and compared with the charge-transfer absorption of tetracyanoethylene and the same donors. The electron affinity of indanetrione, 1.1 eV, determined in this fashion, was in excellent agreement with the predictions.
What is a Dispositive

The distinct French and Italian concepts of appareil/apparato and dispositif/dispositivo have frequently been rendered the same way as "apparatus" in English. This presents a double problem since it collapses distinct conceptual lineages from the home languages and produces a false identity in English. While there are good reasons for which translators have chosen to use "apparatus" for dispositif , there is growing cause for evaluating the theoretical and empirical specificity of each concept, and either to rethink the rendering as "apparatus" or to keep in mind the specific philosophical trajectories of each one. In particular, the ongoing release of Michel Foucault’s College de France lecture courses (in which the term is frequently used), and the essays by Gilles Deleuze and Giorgio Agamben bearing directly on the dispositif and the dispositivo present a strong case for reevaluating the usage and rendering of these concepts. This paper presents a number of minute considerations on the productive distinction between them.
Mycobacterium tuberculosis Impairs Dendritic Cell Functions through the Serine Hydrolase Hip1

Mycobacterium tuberculosis is a highly successful human pathogen that primarily resides in host phagocytes, such as macrophages and dendritic cells (DCs), and interferes with their functions. Although multiple strategies used by M. tuberculosis to modulate macrophage responses have been discovered, interactions between M. tuberculosis and DCs are less well understood. DCs are the primary APCs of the immune system and play a central role in linking innate and adaptive immune responses to microbial pathogens. In this study, we show that M. tuberculosis impairs DC cytokine secretion, maturation, and Ag presentation through the cell envelope–associated serine hydrolase, Hip1. Compared to wild-type, a hip1 mutant strain of M. tuberculosis induced enhanced levels of the key Th1-inducing cytokine IL-12, as well as other proinflammatory cytokines (IL-23, IL-6, TNF-α, IL-1β, and IL-18) in DCs via MyD88- and TLR2/9-dependent pathways, indicating that Hip1 restricts optimal DC inflammatory responses. Infection with the hip1 mutant also induced higher levels of MHC class II and costimulatory molecules CD40 and CD86, indicating that M. tuberculosis impairs DC maturation through Hip1. Further, we show that M. tuberculosis promotes suboptimal Ag presentation, as DCs infected with the hip1 mutant showed increased capacity to present Ag to OT-II– and early secreted antigenic target 6–specific transgenic CD4 T cells and enhanced Th1 and Th17 polarization. Overall, these data show that M. tuberculosis impairs DC functions and modulates the nature of Ag-specific T cell responses, with important implications for vaccination strategies.

Cytomegalovirus infections of the oral cavity: A report of six cases and review of the literature

Cytomegalovirus is responsible for a significant percentage of asymptomatic viral infections worldwide. Although virtually any cell or organ may be infected, involvement of the oral cavity is uncommon. Only nine well-documented examples of intraoral cytomegalovirus infections were found in a review of the English-language literature. We report six additional examples, five of which possessed unique clinical and histopathologic characteristics. The light and electron-microscopic features of cytomegalovirus are discussed, as well as diagnostic adjuncts such as immunohistochemistry and deoxyribonucleic acid in situ hybridization.
Wintertime Infiltration Rates in Mobile Homes

The infiltration in mobile homes can be reduced by treatments such as caulking or adding a special sheathing board material. Present standards set limits on the infiltration rates in mobile homes. Reduction in infiltration rates are accompanied by reductions in heating, ventilating and air-conditioning (HVAC) equipment sizing and operation cost. Unfortunately, there is a general lack of actual field data to determine infiltration rates of mobile homes and the general dependence of infiltration on wind and temperature differences. A field test setup including two unoccupied mobile homes is described. The facility permits a measure of weather, consumption, infiltration rate, and surface temperatures. Data are now presented comparing the winter performance of the two mobile homes. The homes are identical on all counts except that one is treated with a special sheathing board while the other is caulked. The data indicate a general parabolic dependence of infiltration on wind (and a linear dependence on temperature difference) with consistently lower values of infiltration rate for the board-sheathed home than for the caulked home.
A consistent 2D/1D approximation to the 3D neutron transport equation

Abstract A new “2D/1D” equation is proposed to approximate the 3D linear Boltzmann equation. The approximate 2D/1D equation preserves the exact transport physics in the radial directions x and y but employs diffusion physics in the axial direction z. The 2D/1D equation can be systematically discretized, yielding accurate simulation methods for 3D reactor core problems. The resulting 2D/1D solutions are more accurate than 3D diffusion solutions, and are less expensive to calculate than standard 3D transport solutions. In this paper, we (i) show that the simplest 2D/1D equation has certain desirable properties, (ii) systematically discretize this equation, (iii) derive stable iteration schemes for solving the discrete system of equations, and (iv) give numerical results for simple problems that confirm the theoretical predictions of accuracy and iterative stability.
Provision of deep procedural sedation by a pediatric sedation team at a freestanding imaging center.

Freestanding imaging centers are popular options for health care systems to offer services accessible to local communities. The provision of deep sedation at these centers could allow for flexibility in scheduling imaging for pediatric patients. Our Children’s Sedation Services group, comprised of pediatric critical care medicine and pediatric emergency medicine physicians, has supplied such a service for 5 years. However, limited description of such off-site services exists. The site has resuscitation equipment and medications, yet limited staffing and no proximity to hospital support. To describe the experience of a cohort of pediatric patients undergoing sedation at a freestanding imaging center. A retrospective chart review of all sedations from January 2012 to December 2012. Study variables include general demographics, length of sedation, type of imaging, medications used, completion of imaging, adverse events based on those defined by the Pediatric Sedation Research Consortium database and need for transfer to a hospital for additional care. Six hundred fifty-four consecutive sedations were analyzed. Most patients were low acuity American Society of Anesthesiologists physical class ≤ 2 (91.8%). Mean sedation time was 55 min (SD ± 24). The overwhelming majority of patients (95.7%) were sedated for MRI, 3.8% for CT and <1% (three patients) for both modalities. Propofol was used in 98% of cases. Overall, 267 events requiring intervention occurred in 164 patient encounters (25.1%). However, after adjustment for changes from expected physiological response to the sedative, the rate of events was 10.2%. Seventy-five (11.5%) patients had desaturation requiring supplemental oxygen, nasopharyngeal tube or oral airway placement, continuous positive airway pressure or brief bag valve mask ventilation. Eleven (1.7%) had apnea requiring continuous positive airway pressure or bag valve mask ventilation briefly. One patient had bradycardia that resolved with nasopharyngeal tube placement and continuous positive airway pressure. Fifteen (2.3%) patients had hypotension requiring adjustment of the sedation drip but no fluid bolus. Overall, there were six failed sedations (0.9%), defined by the inability to complete the imaging study. There were no serious adverse events. There were no episodes of cardiac arrest or need for intubation. No patient required transfer to a hospital. Sedation provided at this freestanding imaging center resulted in no serious adverse events and few failed sedations. While this represents a limited cohort with sedations performed by predominately pediatric critical care medicine and pediatric emergency medicine physicians, these findings have implications for the design and potential scope of practice of outpatient pediatric sedation services to support community-based pediatric imaging.
Asymptotic Analysis of a Mode III Stationary Crack in a Ductile Functionally Graded Material

The dominant and higher-order asymptotic stress and displacement fields surrounding a stationary crack embedded in a ductile functionally graded material subjected to anti-plane shear loading are derived. The plastic material gradient is assumed to be in the radial direction only and elastic effects are neglected. As in the elastic case, the leading (most singular) term in the asymptotic expansion is the same in the graded material as in the homogeneous one with the properties evaluated at the crack tip location. Assuming a power law for the plastic strains and another power law for the material spatial gradient, we derive the next term in the asymptotic expansion for the near-tip fields. The second term in the series may or may not differ from that of the homogeneous case depending on the particular material property variation. This result is a consequence of the interaction between the plasticity effects associated with a loading dependent length scale (the plas-tic zone size) and the inhomogeneity effects, which are also characterized by a separate length scale (the property gradient variation).
Why (some) Americans believe in the lie detector while others believe in the guilty knowledge test.

The accuracy of polygraphic lie detection in real life applications is very little better than chance. Yet, at least in the United States, many agencies and the polygraphers themselves have great faith in the technique. The reasons why polygraph examiners, and their clients, genuinely believe in the myth of the polygraph are explained and illustrated. A more plausible method of polygraphic interrogation, the Guilty Knowledge Test (GKT), is described and it is shown how the GKT, but not the lie test, might have resolved doubts about the case of Demjanjuk, the alleged “Ivan the Terrible.”
APPLICATIONS OF THE ROTATING CALIPERS TO GEOMETRIC PROBLEMS IN TWO AND THREE DIMENSIONS

A paper published in 1983 established that the rotating calipers paradigm provides an elegant, simple, and yet powerful computational tool for solving several twodimensional geometric problems. Since then the rotating calipers have been extended to three dimensions, and have been applied to many new problems. In the present paper the history of this tool is reviewed, and stock is taken of the rich variety of computational problems and applications that have been tackled with it during the past thirty years.
Bevacizumab and etoposide combination chemotherapy in patients with recurrent malignant gliomas who failed bevacizumab

Bevacizumab is the current standard of care treatment for recurring malignant glioma patients. However, most of the tumors become resistant to bevacizumab, and there is no standardized, effective chemotherapy for the malignant glioma patients after bevacizumab failure. Retrospective chart review was performed in order to identify the malignant glioma patients treated with oral, metronomic etoposide in combination with bevacizumab after being diagnosed with progressive disease while on bevacizumab. This review was approved by the Institutional Review Board (IRB) of the University of California, Irvine. Six malignant gliomas patients met the inclusion criteria. The median progression-free survival (PFS) for the anaplastic astrocytoma (AA) patients was eight months, and the overall survival was 28 months. The two Glioblastoma Multiforme (GBM) patients showed tumor progression after four to eight weeks of treatment with bevacizumab and etoposide, and died within four months of beginning the etoposide/bevacizumab regimen. In this limited study, patients with AA demonstrated prolonged control on combination treatment with bevacizumab and oral etoposide, despite initial tumor progression on bevacizumab. These results may warrant further investigation on a prospective clinical trial of this combination in AA patients who developed resistance to bevacizumab.
