The group-theoretical structure of the atomic g shell: connection with the alternating group A6 as L2(9)

The special projective linear groups PSL(2l + 1) or L2(2l + 1) of order 2l(2l + 1)(l + 1) can be used to study atomic shells of electrons with angular momentum quantum number l corresponding to the atomic p, d, f, and g shells for l = 1, 2, 3, 4, respectively. For the atomic g shell the group L2(9) is isomorphic with the alternating group A6 on six objects of order 360 or the symmetry group of the 5-dimensional simplex, a 5-dimensional analogue of the tetrahedron with 6 vertices and 15 edges. This leads to the subgroup chain SO(9) ⊃ SO(5) ⊃ L2(9) for the atomic g shell analogous to the subgroup chain SO(7) ⊃ G2 ⊃ L2(7) ≈7O for the atomic f shell. In the L2(9) group only the representations of spherical harmonics or sums thereof, Γ(Yl), with dimensions dim Γ(Yl) or dim Γ(Yl) ± 1 divisible by 9 are found to be individually reducible to irreducible representations (irreps) or sums of irreps of L2(9). This leads to term groupings such as S, PD, G, PF, DH, L, PK, DI, FH, M, FI, PO, DN, HK, R, etc., of increasing total dimension for the irreps of SO(9) for various gn configurations in the atomic g shell.
The Place of Comics in the Modern Hindu Imagination

This article provides an overview of the birth of comics in India; a discussion of the available scholarship to date, which has focused largely on India’s most prominent comic book series, Amar Chitra Katha, and its connections to classical Hindu mythology and modern Hindu nationalist ideology; a roundup of recent developments in Indian comics since the creation of Amar Chitra Katha; and briefly offers some suggestions for further research.
Measurement of protein-DNA interaction parameters by electrophoresis mobility shift assay.

Native gel electrophoresis (mobility shift) assays may be used to obtain quantitative information about the site distribution, equilibria and kinetics of protein-DNA interactions. These applications depend on the ability of the electrophoretic system to resolve the reaction components, and on their stabilities during the separation process Factors which affect the lifetimes and mobilities of protein-DNA complexes during electrophoresis include reaction and electrophoresis buffer composition, pH, and ionic strength; the presence of low molecular weight effectors and enzymatic substrates; the nature and concentration of the gel matrix; the temperature; the molecular weights of protein and DNA; the stoichiometric ratios of their complexes; and the possibility of conformational and configurational isomerization of reaction components. We discuss how these factors influence the acquisition of quantitative data from electrophoretic patterns and band intensities, and present formulas for the estimation of equilibrium constants and rate constants for prototypical DNA-protein interactions.
Radiometric dating and temperature history of banded iron formation–associated hematite, Gogebic iron range, Michigan, USA

Newly developed techniques were used to characterize the age, origin, and temperature history of coarse hematite contained in high-grade iron ore. Three botryoidal specimens from two different mines in the Gogebic iron range near Ironwood, Michigan (USA), yielded (U-Th)/^(21)Ne ages concordant with plateau ^4He/^3He ages. These data reveal that while two of the specimens grew at ca. 772 ± 41 Ma, the third formed 300 m.y. later (453 ± 14 Ma). ^4He/^3He polydomain thermochronometry indicates hematite formation at >80 °C for the older specimens and ∼60 °C for the younger. Fe mobilization and recrystallization in open cavities at 3–5 km subsurface has occurred episodically or possibly continuously over hundreds of millions of years despite a quiescent tectonic setting throughout this interval. While the analyzed specimens are distinct from typical Fe ore, their ages along with structural relationships constrain the onset of iron enrichment to between 1060 and 770 Ma. Cooling of ∼0.5 °C/m.y. ensued between ca. 800 and ca. 550 Ma, declining to ∼0.1 °C/m.y. for the last 550 m.y. These data suggest an erosion rate of ∼6 m/m.y. and ∼5 km of total erosion of the Superior Upland province through the Phanerozoic, and limit unroofing associated with Pleistocene glaciation to <1 km.
A Human Factors Study of Graphical Passwords Using Biometrics

One mode of authentication used in modern computing systems is graphical passwords. Graphical passwords are becoming more popular because touch-sensitive and pen-sensitive technologies are becoming ubiquitous. In this paper, we construct the “BioSketch” database, which is a general database of sketch-based passwords (SkPWs) with pressure information used as a biometric property. The BioSketch database is created so that recognition approaches may be commensurable with the benchmark performances. Using this database, we are also able to study the human-computer interaction (HCI) process for SkPWs. In this paper, we compare a generalized SKS recognition algorithm with the Frechet distance in terms of the intra/inter-class variations and performances. The results show that the SKS-based approach achieves as much as a 7 % and 17 % reduction in equal error rate (EER) for random and skilled forgeries respectively.
Application of genetic algorithm for the improved performance of boost converters

Abstract DC-DC Boost converters play a major role in DC-DC and DC-AC conversion applications like electric vehicle, integration of photovoltaic (PV) and distributed energy resources into the grid. When these converters operate they might introduce electromagnetic interference (EMI) and harmonics into the system. In order to avoid this, passive filters are prominently used. The methodology proposed here makes use of evolutionary computing algorithm in order to generate an optimized filter design for a boost converter. The proposed generic filter design procedure involves three steps, first selecting a suitable filter, second identifying the transfer functions involved, and finally using evolutionary algorithms to optimize the selected filter design. This methodology was implemented for LC filter design for a DC-DC boost converter using genetic algorithm.
Age differences in self-reported anxiety and psychomotor performance.

Summary.-10 young and 10 older adults completed a self-report questionnaire on Debilitative and Facilitative Anxiety both prior to and following 10 psychomotor coding trials. Older adults were higher on Facilitative Anxiety at both times. These scores were negatively correlated with coding task performance for the total group bur not for the individual age groups. There was no age effect for Debilitative Anxiety, although it was lower at Time 2, particularly for older adults. Debilimtive Anxiety was not correlated with psychomotor performance. These results do not support the hypothesis that the psychomotor performance of older adults is differentially negatively affected by anxiety. Considerable artention has been given to the hypothesis that older adults are overaroused relative to younger ones in resting situations and that this overarousal is deleterious to their performance. Yet only a small number of studies have contrasted young and older adults on measures of anxiety, and surprisingly few have assessed the relationship between anxiety and performance. The present study compared 10 young adults (7 women and 3 men, M = 23.3 yr.) and 10 older community-living adults (all women, M = 69.9 yr.) on self-reported anxiety using the Modified Anxiety Achievement Test (3), which contains eight items for measuring facilitative anxiety and eight for debilitacive anxiety. This test was administered both prior to (Time 1) and following (Time 2) 10 30-sec. trials on a modified version of the WAIS Digit-Symbol coding subtest (2). The two age groups were equivalent on WAIS Information subtest scaled scores (Ms = 11.5 and 12.6 for the young and older, respectively). Age x time analyses of variance indicated a significant main effect for age on facilitative anxiety (F1.a = 15.3, p < .001), with the older group reporting significantly higher facilitative anxiety (M = 5.6, SD = 1.4) than the young group (M = 3.0, SD = 1.5). Neither time nor the interaction of age X time approached significance. There was no main-effect for age on debilitative anxiety, but the interaction of age x time approached significance (p < .06). There was a trend for the older group to report a decreased debilitative anxiety at Time 2 (M = 2.4, SD = 2.3) relative to Time 1 (M = 3.7, SD = 2.3). The young group did not differ in self-reported debilitative anxiety at Time 1 (M = 3.2, SD = 1.4) and Time 2 (M = 3.2, SD = 1.3). A Pearson correlation for the total sample approached significance (r = -.43, p < .06) for facilitative anxiety at Time 1 (M = 4.3, SD = 1.8) and total number coded on all 10 trials (M = 220.4, SD = 72.8). The Pearson correlation was significant (r = --.49, p < .03) at Time 2 for facilitative anxiety (M = 4.25, SD = 2.0) and total number coded on all 10 trials. The correlations were nonsignificant for the two age
The Teaching of Advanced Marketing Courses in Specialized Programs

A LTHOUGH the topic assigned to me concerns the teaching of advanced marketing courses in specialized programs, the problems concerned with planning, organizing, and presenting marketing information to students in advanced, specialized courses are fundamentally the same as problems connected with formulating and developing any advanced courses in the marketing field. During the last few years our Association has devoted considerable attention to the improvement of teaching methods in marketing; and the results of our discussions in this direction are directly applicable to the narrower subject I am discussing today. However, opportunity still exists for substantial improvement. Previous speakers have presented a number of problems that still remain to be solved satisfactorily if we are to fulfill our obligations as teachers. I hope that our discussions and exchange of ideas in these meetings may continue, for in this way our problems are clearly outlined and suggestions for their solution are presented and developed. Thus a marked increase in teaching effectiveness should be brought about. The suggestions advanced in this paper are intended to apply particularly to graduate students in specialized programs. No attempt is made to discuss the teaching of all advanced marketing courses nor to apply the suggested courses of action to advanced undergraduate students, although there may be entirely logical applications to these other problems. All institutions offering courses designed especially for graduates, and this applies to the larger schools in particular, attract students from a wide variety of colleges and universities where a diversity of training has been received in undergraduate courses, including marketing courses. Furthermore, students enter upon their graduate work with varying backgrounds and experience both within and without their fields of specialization. Because of these conditions, it appears highly desirable that a brief review of those fundamental principles which have a distinct bearing on the material presented in the specialized course should precede the introduction and analysis of the new, advanced material. Such a procedure serves to clarify and strengthen the foundation upon which the new structure must be built, remedies some of the deficiencies of former training, and starts all members of the class upon a more nearly equal basis. It is important that we do not lose sight of the fact that we must build, and build as solidly as the materials at our command will permit, upon a foundation that has already been laid, strengthening it where necessary, but preserving and reinforcing that which is good, rather than destroying the old foundation and building anew. After all, the primary consideration in all teaching is the student; methods, materials, and teachers are all subordinate to him!
Listening for Silences

Talking with informants in the field lies at the methodological heart of Africanist history and anthropology. Historians and anthropologists rely on formal and informal interviews, surveys, questionnaires, and participant observation in order to generate data from Africans and to privilege an African perspective on society, culture, and change. Fieldwork serves both as a political statement empowering African voices and as a right of passage for Africanists. Vansina's (1965) careful methodological considerations for mining and interpreting the African voice in the form of oral traditions has helped give Africanist history its distinctive character. Collecting and using oral traditions has not been unproblematic, however. Considerable debate surrounds the historicity of oral traditions (for example, Wrigley 1971; Henige 1974; Prins 1979; Miller 1980; Webster 1982; Vansina 1985). In comparison, little attention has been paid to the interview as the encounter central to the production of knowledge. In his Oral Tradition , Vansina was concerned primarily with the chains of transmission of testimony and their possible distortions. Vansina recognized, but did not pursue, how the encounter between informant and researcher influenced the informant's testimony.
Poor Whites of the South

A NUMBER of recent events have tended to revivify the problem and dilemma of the "poor whites" in the South. The literary and dramatic scene, with its flood of literature about the South and its presentations of the South on Broadway, is, of course, one chief factor. It would seem that the Nation has become Tobacco Road conscious to the extent of a relatively new and almost universal caricature of the great body of poor southern rural and industrial folk as poor whites." Along with this convergence of attention, from another direction has come the rediscovery of the farm tenants by both the North and the South emphasizing one aspect of the low standards of living and near-poverty of millions of southern folk brought into focus by the depression. The rise and incidence of regionalism, in which the trend is to inventory the several regions, due to the necessity of the New Deal differentials as well as to the general movement of American Regionalism, have been other factors focusing attention upon the human as well as the physical resources of the southern regions. It seems likely that this last may be the most important of all recent developments in that it furnishes the framnework for the present trend to study the people of the South as human resources in relation to the development of a richer regional and national culture. This study of the southern people is one of the "musts" in the program of research and planning for the next period of development in the South and the Nation. It is commonly said that no region of the Nation has been so completely documented as has the South. This seems quite likely, and certainly never before have there been such comprehensive inventories of its wealth and waste, its resources and prospects, and never before perhaps has there been such high motivation on the part of the South to achieve new realities in regional development and achievement. Howard W. Odumn, in Southern Regions of the United States, has made a most thorough-going analysis of the great resources of the South, both physical and human. He has shown that the region has a superabundance in potentiality of both and needs only the skill and technology of science and trained people to translate them, on the one hand, into capital and wealth, and, on the other, into richer institutions and a superior people. Theoretically, of course, this is the old problem of the conservation and utilization of the people in harmony with land and the folk regional society.
Methylene Blue-Mediated Electrocatalytic Detection of Hexavalent Chromium

We report, for the first time, the design and fabrication of an electrochemical ion (E-ION) sensor for highly specific detection of hexavalent chromium (Cr(VI)). Unlike previously developed electrochemical Cr(VI) sensors, the sensing mechanism relies on the previously unexplored electrocatalytic reaction between Cr(VI) and surface-immobilized methylene blue (MB). The sensor is sensitive, specific, and selective enough to be used in a synthetic aquifer sample. Like many sensors of this class, it is also reagentless, reusable, and compatible with gold-plated screen-printed carbon electrodes. Despite the difference in the sensing mechanism, this E-ION Cr(VI) sensor possesses attributes similar to other MB-based electrochemical sensors, sensors with potential for real world applications.
Thermodynamic stability of transition metals on the Mg-terminated MgB 2 (0001) surface and their effects on hydrogen dissociation and diffusion

The hydrogenation of ${\mathrm{MgB}}_{2}$ is a critical step in the reversibility of several well-known hydrogen storage reactions. Of the many processes that must occur during rehydrogenation, at least two of them take place near the surface: the dissociation of ${\mathrm{H}}_{2}$ molecules and the subsequent diffusion of atomic hydrogen. Using first-principles calculations, we determine the energetic barriers for these processes on the ideal Mg-terminated ${\mathrm{MgB}}_{2}$ (0001) surface, as well as on surfaces containing transition metal dopants (Sc-Zn, Y-Cd, Pt, and Au). The calculated dissociation barrier for ${\mathrm{H}}_{2}$ on the clean surface is 0.89 eV, and the surface diffusion barrier is 0.17 eV. However, we find examples of dopants that significantly decrease the activation barrier for the dissociation of ${\mathrm{H}}_{2}$. Our calculations suggest that Ni, Cu, and Pd are good catalytic candidates for the surface processes involved in ${\mathrm{MgB}}_{2}$ rehydrogenation.
Predictors of cholesterol treatment discussions and statin prescribing for primary cardiovascular disease prevention in community health centers.

Background Although cholesterol guidelines emphasize cardiovascular disease (CVD) risk to guide primary prevention, predictors of statin use in practice are unknown. We aimed to identify factors associated with a cholesterol treatment discussion and statin prescribing in a high-risk population.
An Image Fusion Algorithm with Infrared and Visible Light Based on Estimation Theory

A novel image fusion algorithm is proposed based on EM algorithm.This method infers the iterative process of real scene to fusion images according to EM algorithm based on multi-image model.Varieties of methods,such as Laplace Pyramids,wavelet and gradient pyramids,are discussed and compared with EM algorithm.The digital imitation results show that the robustness of the method is quite good even when fusing the seriously polluted image.
Human pluripotent stem cells as a model of trophoblast differentiation in both normal development and disease

Trophoblast is the primary epithelial cell type in the placenta, a transient organ required for proper fetal growth and development. Different trophoblast subtypes are responsible for gas/nutrient exchange (syncytiotrophoblasts, STBs) and invasion and maternal vascular remodeling (extravillous trophoblasts, EVTs). Studies of early human placental development are severely hampered by the lack of a representative trophoblast stem cell (TSC) model with the capacity for self-renewal and the ability to differentiate into both STBs and EVTs. Primary cytotrophoblasts (CTBs) isolated from early-gestation (6-8 wk) human placentas are bipotential, a phenotype that is lost with increasing gestational age. We have identified a CDX2(+)/p63(+) CTB subpopulation in the early postimplantation human placenta that is significantly reduced later in gestation. We describe a reproducible protocol, using defined medium containing bone morphogenetic protein 4 by which human pluripotent stem cells (hPSCs) can be differentiated into CDX2(+)/p63(+) CTB stem-like cells. These cells can be replated and further differentiated into STB- and EVT-like cells, based on marker expression, hormone secretion, and invasive ability. As in primary CTBs, differentiation of hPSC-derived CTBs in low oxygen leads to reduced human chorionic gonadotropin secretion and STB-associated gene expression, instead promoting differentiation into HLA-G(+) EVTs in an hypoxia-inducible, factor-dependent manner. To validate further the utility of hPSC-derived CTBs, we demonstrated that differentiation of trisomy 21 (T21) hPSCs recapitulates the delayed CTB maturation and blunted STB differentiation seen in T21 placentae. Collectively, our data suggest that hPSCs are a valuable model of human placental development, enabling us to recapitulate processes that result in both normal and diseased pregnancies.
XAR: An Integrated Framework for Semantic Extraction and Annotation

INTRODUCTION The vision of semantic interoperability on a large-scale, such as that envisioned by the concept of the Semantic-Web (Berners-Lee, Hendler & Lassila, 2001), continues to sustain interest and excitement. The availability of automated tools for semantic annotation of data on the open Web is recognized as critical for Semantic-Web enablement. In the process of semantic annotation we annotate significant entities and relationships in documents and pages on the Web, thus making them amenable for machine processing. The time and investment of marking and annotating Web content manually is prohibitive for all but a handful of Web content providers, which leads us to develop automated tools for this task. As an example, consider Web pages of academic researchers with their biographies in free text as shown in Fig 1.
Aortic surgery in pregnancy

Pregnancy engenders changes in hemodynamics and the aortic wall that make a woman more susceptible to aortic dilatation and dissection. This is particularly true of women with aortic dilatation and an aortopathy, including the inherited fibrillinopathies, bicuspid aortic valve, and Turner syndrome. Women in these risk groups may be served best by undergoing elective aortic surgery before becoming pregnant. However, some women present during pregnancy with significant aortic dilatation, rapid expansion, or aortic dissection, and strategies to deal with these situations, while optimizing maternal and fetal outcomes, change as gestation progresses. This review summarizes the approaches to the management of aortic diseases and the conduct of aortic surgery in pregnancy.

Transition from storm wave-dominated outer shelf to gullied upper slope: The mid-Pliocene Orinoco shelf margin, South Trinidad

Shelf-edge deltas are a key depositional environment for accreting sediment onto shelf-margin clinoforms. The Moruga Formation, part of the palaeo-Orinoco shelf-margin sedimentary prism of south-east Trinidad, provides new insight into the incremental growth of a Pliocene, storm wave-dominated shelf margin. Relatively little is known about the mechanisms of sand bypass from the shelf-break area of margins, and in particular from storm-wave dominated margins which are generally characterized by drifting of sand along strike until meeting a canyon or channel. The studied St. Hilaire Siltstone and Trinity Hills Sandstone succession is 260 m thick and demonstrates a continuous transition from gullied (with turbidites) uppermost slope upward to storm wave-dominated delta front on the outermost shelf. The basal upper-slope deposits are dominantly mass-transport deposited blocks, as well as associated turbidites and debrites with common soft-sediment-deformed strata. The overlying uppermost slope succession exhibits a spectacular set of gullies, which are separated by abundant slump-scar unconformities (tops of rotational slides), then filled with debris-flow conglomerates and sandy turbidite beds with interbedded mudstones. The top of the study succession, on the outer-shelf area, contains repeated upward-coarsening, sandstone-rich parasequences (2 to 15 m thick) with abundant hummocky and swaley cross-stratification, clear evidence of storm-swell and storm-wave dominated conditions. The observations suggest reconstruction of the unstable shelf margin as follows: (i) the aggradational storm wave-dominated, shelf-edge delta front became unstable and collapsed down the slope; (ii) the excavated scars of the shelf margin became gullied, but gradually healed (aggraded) by repeated infilling by debris flows and turbidites and then new gullying and further infilling; and (iii) renewed storm wave-dominated delta-front prograded out across the healed outer shelf, re-establishing the newly stabilized shelf margin. The Moruga Formation study, along with only a few others in the literature, confirms the sediment bypass ability of storm-wave dominated reaches of shelf edges, despite river-dominated deltas being, by far, the most efficient shelf-edge regime for sediment bypass at the shelf break.

ExtensionGuard: Towards runtime browser extension information leakage detection

Many browser extensions process sensitive information, such as bookmarks and browsing history that are available from the browsers, and social security number and password that are shown on web pages. Thus, an increasing interest has been growing among attackers to exploit this new attacking platform to compromise browser security. The most common attacks from malicious extensions include accessing users' sensitive information and leaking them to unauthorized third parties. Some recent studies discussed the possible attacks launched from malicious extensions but few proposed practical solutions to address the issue. In this paper, we present the ExtensionGuard, an optimized and customizable dynamic taint tracking system that can closely track the sensitive information processed by browser extensions, and detect any information leakage events at runtime. We evaluate ExtensionGuard against a set of malicious and benign extensions. The evaluation results show that ExtensionGuard is able to effectively mitigate various information leakage attacks without incurring high performance overhead.
Robotic-Assisted Inguinal Lymphadenectomy: The University of Texas M.D. Anderson Cancer Center Approach

Robotic-assisted inguinal lymphadenectomy (RAIL) was developed for the surgical staging of the inguinal region for squamous cell carcinoma of the penis in the clinically node negative setting, although this technique can be applied to any genital or lower extremity malignancy that has drainage to the inguinal lymph nodes (vulvar carcinoma, melanoma). This technique has been developed to minimize the morbidity associated with the standard open approach, which includes both infectious complications and lymphedema. Despite the minimally invasive approach, standard oncologic principles are maintained, including adherence to the dissection limits and complete removal of lymph nodes within the dissection template.
Multiple phases of mg-calcite in crustose coralline algae suggest caution for temperature proxy and ocean acidification assessment: lessons from the ultrastructure and biomineralization in Phymatolithon (Rhodophyta, Corallinales)1.

Magnesium content, strongly correlated with temperature, has been developed as a climate archive for the late Holocene without considering anatomical controls on Mg content. In this paper we explore the ultrastructure and cellular scale Mg-content variations within four species of North Atlantic crust-forming Phymatolithon. The cell wall has radial grains of Mg-calcite whereas the interfilament (middle lamella) has grains aligned parallel to the filament axis. The proportion of interfilament and cell wall carbonate varies by tissue and species. Three distinct primary phases of Mg-calcite are identified: interfilament Mg-calcite (mean 8.9 mol% MgCO3), perithallial cell walls Mg-calcite (mean 13.4 mol% MgCO3), and hypothallium Mg-calcite (mean 17.1 mol% MgCO3). Magnesium content for the bulk crust, an average of all phases present, shows a strongly correlated (R2= 0.975) increase of 0.31 mol% MgCO3/°C. Of concern for climate reconstructions is the potential for false warming signals from undetected post-grazing wound repair carbonate that is substantially enriched in Mg, unrelated to temperature. Within a single crust, component carbonates can range from Mg content as stable as aragonite (8 mol% MgCO3), up to 150% higher (20 mol% MgCO3) a predicted unstable high magnesium calcite. It is unlikely that existing current predictions of ocean acidification impact on coralline algae, based on saturation states calculated using average Mg contents, provide an environmentally-relevant estimate.

‘I am Slave to no Sect’: Brownson’s Defense of Intellectual Freedom and Doubt

Chapter 4 begins with Brownson’s brief foray into socialist circles and is followed by a description of his attachment to Unitarianism, where he served as a minister beginning in 1831. Cortes shows how the prevalence of ‘the theology of the people’ in this era combines with the proliferation of religious publications to create a culture that is extremely attuned to religious change and demands that religious peripatetics like Brownson define their religious identity. Defending his right to religious change, Brownson proceeds to register respect for skepticism and religious doubt. The chapter concludes with Brownson’s continued concern over the clash of confessions.

Finite Extension and Torsion of Thin Elastic Strips

The large extension and torsion of highly elastic bars of slender section is examined by an approximate method. The approach treats the cylinder of elongated section as a membrane of non-uniform thickness and the problem reduces to a one-dimensional problem when the deformation is the same at each section. The solution for a particular strain-energy function can be obtained by numerical integration. Results are presented for a Mooney material and for a material with an empirical strain-energy function for a bar with an elongated rectangular section. When the section is not symmetrical about the centroid, the location of the axis of torsion varies with the amount of twist, and results showing the migration of the axis of torsion for a tapered section are given.
Renal artery reconstruction

A variety of operative techniques has been used to correct renal artery stenoses in the past 20 years. These techniques include aortorenal bypass using saphenous vein, autogenous hypogastric artery or synthetic material, endarterectomy, renal artery reimplantation, and extra-anatomical procedures such as splenorenal anastomosis and hepatorenal bypass. Whereas thromboendarterectomy and renal artery reimplantation are only suitable for proximal or orificial lesions, aortorenal bypass can be employed for either atherosclerotic disease or fibromuscular dysplasia of the renal artery.
Independent contributions of semantic and phonological working memory to spontaneous speech in acute stroke

Abstract Patients with left hemisphere stroke often have language deficits which impair their ability to produce phrases and sentences. One possible source of these speech impairments is the disruption of verbal working memory (WM). Single-case studies of chronic stroke have suggested the existence of a WM capacity specific to maintaining semantic information that is critical for preparing multiple words in phrases prior to speech onset (Freedman, Martin, & Biegler, 2004; Martin & Freedman, 2001; Martin & He, 2004; Martin, Miller, & Vu, 2004). The current study tested this hypothesis by examining spontaneous narrative language production and working memory capacities in a large sample of individuals at the acute stage of stroke (N = 36), prior to the reorganization of function or strategy development. Here we show using a multiple regression approach that patients' semantic but not phonological WM capacity had an independent contribution in predicting phrasal elaboration and increasing utterance length whereas patients’ phonological but not semantic WM capacity had an independent contribution in predicting a more rapid speech rate. Importantly, neither WM capacity independently predicted grammatical abilities in speech, implying that the other relations did not result from overall severity. These results indicate that separable semantic and phonological WM components exist that support different aspects of narrative speech. To our knowledge, this is the first study to examine spontaneous speech in a large group of acute stroke patients demonstrating a critical relationship between working memory and the ability to produce more words in phrases and longer utterances.
Comparison of the Tolerability of Busulfan, Cyclophosphamide, Etoposide (BuCyVP) Versus Carmustine, Etoposide, Cytarabine, Melphalan (BEAM) for Autologous Hematopoietic Cell Transplant (AHCT) in Hodgkin Lymphoma

Background BuCyVP and BEAM are two commonly used conditioning regimens for AHCT. Previous literature has reported improved outcomes with BEAM compared to BuCyVP in Hodgkin lymphoma (HL) patients, although results in non-Hodgkin lymphoma (NHL) patients are scarce but similar. Our institution switched from using BuCyVP to BEAM as AHCT conditioning for HL in 2016. We conducted a retrospective study to evaluate tolerability and resource utilization with the two regimens. Given limited data and comparable outcomes, this may influence decisions to use one regimen over the other in patients with NHL. Objectives Assess resource utilization and toxicity of BEAM vs. BuCyVP in patients undergoing AHCT for HL. The primary endpoint was hospital length of stay (LOS). Secondary outcomes were 30-day readmission rates, incidence of fever, time to neutrophil and platelet engraftment, incidence of transfer to intensive care unit (ICU), time on intravenous (IV) opioids, and incidence of diuretic and breakthrough antiemetic use. Methods Beginning March 2016, BEAM replaced BuCyVP as the standard conditioning regimen for AHCT for HL at our institution. We retrospectively reviewed medical records of HL patients receiving BuCyVP with pharmacokinetic (PK)-guided therapeutic dose monitoring (TDM) of busulfan from October 2014 through March 2016 (N = 19) and BEAM from April 2016 through September 2017 (N = 18). Results BuCyVP recipients had significantly longer average hospital LOS, relative to both admission date (21 vs. 19 days, p Conclusions Compared to BuCyVP, patients receiving BEAM as conditioning for AHCT for HL had significantly shorter hospital LOS, fewer episodes of fevers and required less IV opioids and furosemide. However, there was no difference in other endpoints evaluated (e.g., neutrophil engraftment, ICU transfer and breakthrough antiemetic use). Our study provides the background information on expected resource utilization and toxicities for the two regimens and will assist in decisions regarding use of these regimens in NHL patients where outcomes between the two are comparable

Alterations in ventral attention network connectivity in individuals with prediabetes.

Objective Type 2 diabetes (T2D) is associated with aberrant neural functioning; however, the point at which brain function alterations occur in the progression of T2D is unknown. Here, we tested for differences in functional connectivity in adults with prediabetes and healthy individuals. We hypothesized that prediabetes, defined by glycated hemoglobin (HbA1c) 5.7-6.4% would be associated with disruptions in default mode network (DMN) connectivity. Methods Fourteen brain networks were tested in 88 adults (prediabetes: n = 44; HbA1c = 5.8±0.2%; healthy: n = 44; HbA1c = 4.7±0.2%) matched for sex, age, and BMI. Results We did not find differences in DMN connectivity between groups. Individuals with prediabetes showed stronger connectivity between the ventral attention network and (1) a visual network (pFWE = 0.0001); (2) a somatosensory network (pFWE = 0.0027). Individuals with healthy HbA1c showed stronger connectivity of the ventral attention network and (1) cingulo-opercular network (pFWE = 0.002); (2) a thalamic-striatal-visual network (pFWE = 0.001). Conclusions Relative to individuals with prediabetes, those with a healthy HbA1c showed stronger connectivity between brain networks underlying self-control and attention to stimuli. In contrast, those with prediabetes demonstrated stronger connectivity between brain networks associated with sensory and attention to stimuli. While T2D reported contribute to decreased DMN connectivity, prediabetes is characterized by a shift in functional connectivity from a self-control network towards increasing connectivity in sensory network.
Upper gastrointestinal symptoms and associated endoscopic and histological features in patients receiving immune checkpoint inhibitors.

Background: Immune checkpoint inhibitors (ICIs) have demonstrated effectiveness in treating many malignancies. Gastrointestinal (GI) adverse events are commonly reported; however, few reports describe upper GI tract toxic effects. We aimed to describe clinical features of upper GI injury related to ICI. Methods: We studied consecutive patients who received ICIs between April 2011 and March 2018 and developed upper GI symptoms requiring esophagogastroduodenoscopy (EGD). Results: Sixty patients developed upper GI symptoms between ICI initiation and 6 months after the last infusion. Among patients who had both EGD and colonoscopy (n = 38), 21 had endoscopic evidence of inflammation involving both the upper and lower GI tract. Overall, histological signs of inflammation of the stomach were evident in 83% of patients, but inflammation of the duodenum in 38%. Total of 42 patients had other risk factors of gastritis, i.e., chemotherapy, radiotherapy, and non-steroidal anti-inflammatory drugs. Only isolated gastric inflammation was seen on endoscopy in patients without these risk factors. The rates of ulceration were similar in the cohorts with and without other risk factors for gastritis. Isolated upper GI inflammation was related to anti-PD-1/L1 in 47% of patients. Immunosuppressive therapy in our cohort with upper GI toxicity consisted of steroids (42%) and infliximab or vedolizumab (23%). Most isolated upper GI symptoms were treated with proton pump inhibitors (65%) or H2 blockers (35%). Conclusion: We observed a correlation between ICI use and onset of upper GI inflammation even when other risk factors were excluded. Gastric involvement was evident more often than duodenal involvement on endoscopic and histological level.

Near-infrared photoimmunotherapy through bone.

Near-infrared photoimmunotherapy (NIR-PIT) is a molecularly targeted cancer phototherapy that is based on injecting a conjugate of a silicon-phthalocyanine derivative, IRdye 700DX (IR700), and a monoclonal antibody that targets an expressed antigen on the cancer cell surface. Subsequent local exposure to NIR light results in the rapid and highly selective immunogenic cell death of targeted cancer cells. Because many cancers grow in bones through which light does not penetrate well, the goal of this study was to determine if NIR-PIT can effectively treat cancers in bone. A bovine rib was used as a bone sample. Because the sample's NIR light transmittance was shown to be approximately 4.52% in preliminary tests, it was hypothesized that a maximum radiation dosage of 128 and 1500 J/cm2 would be sufficient to induce cell death in in vitro target cells and in vivo mouse tumor models, respectively. Cell viability was measured through bioluminescence studies comparing relative luciferase activity, as well as a cytotoxicity assay. In the in vitro model, tumor cell viability was significantly decreased after 64 and 128 J/cm2 NIR light irradiation through the bone. An in vivo mouse tumor model also showed that 1500 J/cm2 NIR light irradiation through the bone significantly reduced tumor viability at both 24 and 48 hours posttreatment compared to the control group (P = .026 and .040 respectively). Therefore, despite limitations in light transmission, NIR-PIT nevertheless is capable of effectively treating cancers within bone.
Lessons Learned from Implementation of a Web-Based Environmental Health and Safety Management Database in an Academic Medical Center

An environmental health and safety program for an academic medical center involves managing complex and diverse safety issues. The ability to ensure that required activities are performed and documented as well as ready access to environmental health and safety data to internal stakeholders are a few of the benefits that implementing a centralized environmental health and safety database can provide. The Environmental Health & Safety Department at the University of Texas Medical Branch is organized into operational groups based upon specialty (biological safety, radiation safety, occupational safety, fire safety, and environmental protection management). Historically, the organization has followed a decentralized approach to data management, with each specialty keeping data in their own format and inaccessible to employees in other specialties. Beginning in 2014, the department began the implementation of a unified environmental health and safety database. This database allows for a standardized approach ...
Richard G. Dudley, Jr., MD: Caring in Forensic Psychiatry Practice

A few years ago, I was invited to give a lecture at the Yale Law School on the performative dimensions of the forensic psychiatry report. Before I could even settle down to my task, a member of the law faculty approached me. She asked whether I knew Richard Dudley and placed a copy in my hands of
Urine Dipstick: Blood – The Spectrum of Red

Dipstick urinalysis for blood is a quick, easy, noninvasive and relatively inexpensive test to perform. Of note, this test should only be performed in the appropriate clinical setting due to potential risks to the patient and unnecessary costs if an evaluation is undertaken for false positive results. It is a screening test and if positive, should always be followed up with urine microscopy. The focus of this chapter is the urine dipstick test for blood: the test itself, sensitivity and specificity, factors associated with false positive and false negative results, indications/recommendations, risk factors, differential diagnoses and appropriate referrals.
The Jarrow/Turnbull Default Risk Model Evidence from the German Market

In this article we estimate default intensities within the continuous time Jarrow/Turnbull (1995) model from daily observations of German bank bond prices, based on the default-free term structure estimated from the Svensson (1994) model provided by the Deutsche Bundesbank. Cross-sectional and time-series estimations are performed. We show that pricing errors from the term structure estimation are passed on to the Jarrow/Turnbull model and that estimated default intensities strongly depend on the estimation period and on the bond used for estimation. This result strongly supports separate estimation over cross-sectional estimation. We cannot Infer a significant Influence of liquidity on the default intensities. We show that the assumptions of the Jarrow/Turnbull model are not sound with the underlying data. Furthermore, we Investigate the optimum volume of data required to provide reasonable estimates of the default Intensity. By this we show that daily calibration need not minimize the ex-ante pricing errors. Comparisons with other literature, where default-risky term structures are estimated separately from the defaultfree term structure, show that even using a very simple model the pricing errors can be decreased substantially.

Comparing Fathers’ and Mothers’ Perspectives About Their Child’s Autism Spectrum Disorder

Mothers are often the primary parent participants in autism spectrum disorder (ASD) research. As a result, little is known about fathers' perceptions regarding their children's ASD and whether these perceptions differ from mothers'. Given the limited information available regarding fathers' perceptions about their children's ASD, this study aimed to investigate father variables (stress, coping, support, and perception of disability) and how they compare to mothers'. Participants were 361 biological parents (294 mothers and 67 fathers) of children on the autism spectrum who participated in a larger study. Results revealed significant differences between mothers' and fathers' self-reported stress and coping. Understanding differences between parents' perspectives has both research and clinical implications for working with families raising children on the autism spectrum.
The Theme of Terrorism in Algerian Contemporary Novel: Selected Examples from the Black Decade

This research is concerned with studying the most important social, ethical, and political issues that were dealt with by the Algerian novelist discourse during the bloody decade, as these writers are considered among the prominent signs in the field of Algerian criticism and creativity, due to the abundance of their productions and creativity in the field of fictional discourse. What the Algerian people were exposed to during that period, and how the country turned in a short period into a volcano of sedition embodied by terrorist operations, so they were able to convey this tragedy in a creative artistic form dominated by the conflict between religion, politics and terrorism, and what prompted us to choose this topic is the urgent desire to shed light on a critical period in the history of Algeria, monitoring the psychological effects produced by the events of the black decade, which we still touch till this day.
Design of a Stacked C-DAC Output Stage with Feed-Forward Assisted Cascode Charging in 16 nm FinFET Technology

This paper presents the design and analysis of a stacked C-DAC output stage with feed-forward assisted cascode charging in 16 nm FinFET technology. The presented design operates with input signals in a frequency range from a few hundred MHz up to 6 GHz. Simulation results of the proposed design show that output power can be more than doubled compared to a reference design without stacked inverter while maintaining a SFDR over frequency of better than 65 dBc and two-tone intermodulation distortion of better than −68 dBc.The main linearity limit of the stacked inverter design is overcome by addition of a capacitive feed-forward branch.
