Variations of Sexual Scripts Relating to Concurrency by Race, Class, and Gender in South Africa

It is unclear whether higher rates of sexual partner concurrency in Black South Africans are due to socioeconomic or cultural factors. We used a nationally representative sample of 9,728 individuals aged 16 to 55 from a study conducted in 2009 to examine how the norms pertaining to concurrency and the practice of concurrency vary by race, class, and gender. The percentage of men reporting point concurrency was 14%, 6.5%, and 2.5% in Blacks, coloreds, and Whites, respectively (p < 0.001). These percentages increased to 45.7%, 24.7%, and 11.7%, respectively, for those reporting lifetime concurrency (p < 0.001). In all the racial groups, men exhibited more favorable attitudes toward concurrency than women did. For a range of indicators, White men and women had less favorable attitudes toward concurrency than Black men and women. These differences remained after controlling for a range of confounding variables. In the adjusted logistic regression model, reported concurrency in men was associated with a younger age, Black race, being in the lowest income tertile, not being in a stable relationship, and expressing various positive attitudes toward concurrency.
A Digital Time Delay Measurement Technique and Phase-Locked Loop Requirements in a Standard CMOS Process

A digital architecture is proposed for measuring time delay increments much smaller than the clock period of a practical operating speed in a standard CMOS process. The technique employs correlated double sampling (CDS), a time-interleaved finite impulse response (FIR) averaging and infinite impulse response (IIR) noise filtering. A system with 200ns peak to peak delay deviation and 10-bit resolution requirement is presented in a 0.5mum CMOS process with an area estimate of 3.5 mm2 and power estimate of 60 mW
Multiphase Strengthened Nickel Base Superalloys Containing Refractory Carbide Dispersions

The feasibility of improving the mechanical properties of nickel base superalloys using multiphase particle strengthening and engineered grain structures was investigated. Five new nickel base superalloys containing dispersions of suitable combinations of y', HfC, and ~203 were designed, manufactured, and evaluated. In general, the y', HfC, and ~203 particle dispersions were selected to provide optimum stress rupture strength levels at low (<1073K or 8OOC), intermediate (1073-1223~ or 800-95OC), and high service temperatures (>1223~ or 95OC). The best mechanical properties were obtained for Alloy 5, which was produced by incorporating fine HfC and Y2O3 particles into the commercial Y-Y' alloy MERL76 using the Rapid Solidification+Mechanical Dispersing technique. After consolidation, zone annealing heat treatments were successfully applied to the alloy to produce large columnar grains by secondary recrystallization for higher temperature stress rupture strength. The engineered grain structures that resulted had an average transverse grain size of approximately 0.7 mm and a grain aspect ratio of greater than ten. The projected 1089K (815C) 1000 hour rupture strength of this alloy was 393 MPa (57 ksi), which is a 14% increase over the 345 MPa value for ~~6000. Since MA6000 and Alloy 5 contained similar y' and oxide particle dispersions, the improved intermediate temperature stress rupture strength of Alloy 5 was thought to have resulted from the dispersion of fine HfC particles.

An online BPN gain adapter for PID through PLC on a conical tank system

The PID controller is of great importance to both the researchers and the industrialists as it proves to be robust for linear single input single output processes. However the PID has limitations with non linear and higher order systems. In this research work, an online back propagation neural network gain adapter for PID controller is developed using the ladder functions of PLC and implemented in a non-linear conical tank system. The real time result for steady state performance is compared with the conventional PID controller. The controller track the set point quicker than the PID as the gain values are continuously updated based with respect to the changes in the process. The controller is also validated in real time for servo regulatory and disturbance rejection characteristics on the conical tank system. The online back propagation gain adapter for PID controller developed in PLC is more robust to real time changes and performs better than the PID controller on the conical tank system.
Airway obstruction due to incarceration of the epiglottis into the epiglottic bars during general anesthesia with a new perilaryngeal airway (CobraPLA).

The CobraPLATM is an alternative device for airway management. We report a case of airway obstruction caused by incarceration of the epiglottis in the epiglottic bars of the CobraPLATM during general anesthesia. Although the CobraPLATM was placed without difficulty on the first attempt, signs of airway obstruction were noted 2 h after insertion of the CobraPLATM. Using fiberoptic bronchoscopy, we observed incarceration and distortion of the epiglottis by the epiglottic bars of the CobraPLATM (Figure 1), obstructing the view of the vocal cords. It appears that the distal portion of the CobraPLATM moved upward, from the hypopharynx to the mesopharynx, entrapping the epiglottis in the epiglottic bars. After reinsertion of the CobraPLATM, the airway was restored. The CobraPLATM is a supraglottic airway that shares some features with the laryngeal mask airway, including epiglottic bars. However, the laryngeal mask airway has only two bars, whereas the CobraPLATM has six narrowly spaced bars. Incarceration of the epiglottis between the epiglottic bars may be facilitated by the narrow spacing in the CobraPLATM.
Duloxetine in the treatment of major depressive disorder: a double-blind clinical trial.

BACKGROUND Duloxetine hydrochloride, a dual reuptake inhibitor of serotonin and norepinephrine, was evaluated for therapeutic efficacy and safety/tolerability in the treatment of major depression. METHOD In an 8-week multicenter, double-blind, placebo-controlled study, 173 patients (aged 18-65 years) with DSM-IV major depressive disorder were randomly allocated to receive placebo (N = 70), duloxetine (N = 70), or fluoxetine, 20 mg q.d. (N = 33). Duloxetine dose was titrated in the first 3 weeks in a forced-titration regimen from 40 mg (20 mg b.i.d.) to 120 mg/day (60 mg b.i.d.). Patients were required to have a Clinical Global Impressions (CGI)-Severity of Illness scale score of at least moderate severity (> or = 4) and a 17-item Hamilton Rating Scale for Depression (HAM-D-17) total score of at least 15. Patients could not have had any current primary DSM-IV Axis I diagnosis other than major depressive disorder, or any anxiety disorder as a primary diagnosis within the past year, excluding specific phobias. The primary efficacy measurement was the HAM-D-17 total score, and secondary measures included the Montgomery-Asberg Depression Rating Scale, CGI-Severity of Illness and CGI-Improvement, and Patient Global Impression of Improvement. Safety was evaluated by recording the occurrence of discontinuation rates and treatment-emergent adverse events and by measurement of vital signs and laboratory analytes. RESULTS Duloxetine was superior to placebo in change on the HAM-D-17 (p = .009). Estimated probabilities of response and remission were 64% and 56%, respectively, for duloxetine, compared with 52% and 30% for fluoxetine and 48% and 32% for placebo. Duloxetine was numerically superior to fluoxetine on the primary and most of the secondary outcome measures. In general, duloxetine was well tolerated; 76% of patients achieved the maximum dose, and insomnia and asthenia were the only adverse events reported statistically significantly (p < .05) more frequently by duloxetine-treated patients compared with placebo-treated patients. CONCLUSION These data indicate that duloxetine is efficacious for the treatment of major depressive disorder and is well tolerated and safe.
Blood pressure and intellectual function in elderly subjects.

OBJECTIVE to assess the relationship between hypertension and cognitive function in elderly subjects. METHODS 17 subjects with uncomplicated hypertension (nine male, eight female) and 27 control subjects with similar educational level and age (18 male, nine female) were studied. These individuals were recruited, according to strict selection criteria, from a random sample of 120 elderly subjects living in the community, who had a normal Mini Mental State score. An extensive neuropsychological test battery, sensitive to mild cognitive impairment, was administered in standard conditions to measure attention, concentration and judgement, psychomotor speed, memory and learning. Affective disorders were also evaluated. In all patients a computed tomography scan was performed. RESULTS subjects with high blood pressure had lower mean levels of performance in attentional measures; tapping test (inhibition of incorrect answers), three words-three shapes test (attempts; incidental memory) and reaction time to multiple stimuli. They also scored worse in clusters 1 and 2 of the Hamilton rating scale for depression. Confluent white matter lesions were found in nine hypertensive subjects (52.9%) and five controls (18.5%; P = 0.0170). Lacunes were demonstrated in 11 hypertensive (64.7%) and four normotensive people (14.8%; P = 0.0007). In a multivariate analysis (logistic regression), three cognitive variables (tapping, Hamilton cluster 2 and Hamilton total score) remained significantly associated with hypertension, independently of the presence of cerebral lesions. CONCLUSIONS in elderly otherwise normal hypertensive subjects, an attentional impairment may occur, which appears to be functional and possibly reversible rather than structural and progressive.
Seeing is Believing: The Role of ‘Preconscious' Perceptual Processing in Delusional Misidentification

We have no introspective knowledge of the effects of preconscious processing on our perceptions. We are, therefore, not aware that our expectancies may have prejudiced our perceptions. Expectancies tend to foster perceptions with which they are consonant. Therefore false expectations, driven by false beliefs, may result in misperceptions which reinforce those false beliefs. This morbid cycle is central to the delusional misidentification syndromes. This cycle, with positive feedback, is intrinsically unstable, which helps to explain brief episodes of delusional misidentification. Good sensory data, strong links between sense data and memory, and good judgement will all help to prevent misperceptions. The less these constraints are disrupted, the stronger will be the psychological forces needed to generate a delusional misidentification. It is likely that suspiciousness generates particularly assertive effects on preconscious processing of perceptions. Abnormalities of perceptual processing in patients with schizophrenia explain their proclivity to delusional misidentification.
Fusarium temperatum sp. nov. from maize, an emergent species closely related to Fusarium subglutinans

A large number of Fusarium isolates closely related to F. subglutinans were collected from maize in Belgium. We used a robust polyphasic approach to describe a new biological species, Fusarium temperatum, within the Gibberella fujikuroi species complex. F. temperatum can be distinguished from F. subglutinans and from other Fusarium species within the Gibberella fujikuroi species complex with AFLP fingerprint profile, differences in the translation elongation factor 1-α and β-tubulin DNA sequence and interspecies mating compatibility analyses. Intraspecies mating compatibility suggests that sexual reproduction might be common for field isolates of F. temperatum, and reliable female fertile mating population tester strains were proposed for this heterothallic species.
Isolation of Citrobacter sp. mutants defective in decolorizing malachite green

To identify genes involved in the decolorization of malachite green, random mutants generated by transposon insertion in the malachite green‐decolorizing bacterium, Citrobacter sp. were isolated. The resulting mutant bank yielded 24 mutants with complete defects in their abilities to decolorize malachite green. Southern hybridization with a Tn5 fragment as a probe showed a single hybridized band in 7 mutants, which appeared to have insertions at different sites of the chromosome. The Tn5‐inserted genes were isolated and the DNA sequence flanking Tn5 was determined. Based on a sequence database, the putative protein products encoded by the mg genes were identified as follows. mg3, an ABC transporter homolog; mg6, a LysR‐type regulatory protein; m11, an oxidoreductase; mg17, a MalG protein in the maltose transport system; and mg21, a sugar kinase. The deduced sequences from two mg genes (mg7 and mg18) showed no significant similarity to any protein with a known function, suggesting that these two mg genes encode unidentified proteins that are responsible for the decolorization of malachite green.

Management of pegylated interferon alpha toxicity in adjuvant therapy of melanoma

Introduction: Both native IFNα2b and pegylated IFNα2b (PegIFNα2b) are approved for the adjuvant treatment of high-risk melanoma. Areas covered: This review compares the toxicity profiles of high-dose IFNα2b (HDI) and PegIFNα2b, and provides recommendations on the management of common PegIFNα2b-related toxicities, based on available clinical data and published literature. Expert opinion: The toxicity profile of PegIFNα2b at the approved dose (6 μg/kg/week for 8 weeks then 3 μg/kg/week for up to 5 years) is qualitatively similar to HDI in melanoma. The most common adverse events (AEs) are fatigue, anorexia, hepatotoxicity, flu-like symptoms, injection site reactions and depression. However, fatigue and flu-like symptoms appear less severe with PegIFNα2b, and toxicity seems to occur earlier, whereas with HDI toxicity may increase with time. Most AEs can be managed effectively by dose modification and aggressive symptom control. Dosing to tolerance using a three-step dose reduction schedule to maintain an ECOG performance status of 0 − 1 may enable patients experiencing toxicity to remain on treatment; this can be applied readily in clinical practice. PegIFNα2b is therefore a valuable alternative option for adjuvant treatment in melanoma, with a toxicity profile similar to that of HDI overall but a more convenient administration schedule.
COMPARISON OF SOME PROPERTIES OF PSEUDOMONAS AERUGINOSA ISOLATED FROM INFECTIONS IN PERSONS WITH AND WITHOUT CYSTIC FIBROSIS

Doggett, Robert G. (Texas Institute for Rehabilitation and Research, Houston), Gunyon M. Garrison, and Everett S. Wallis. Comparison of some properties of Pseudomonas aeruginosa isolated from infections in persons with and without cystic fibrosis. J. Bacteriol. 87:427–431. 1964. —Pseudomonas aeruginosa, isolated from the respiratory tract of a group of patients diagnosed as having cystic fibrosis (CF) of the pancreas, attained the ability to produce in its capsule a material which was insoluble in certain organic solvents, such as ethanol. The capsule obtained from P. aeruginosa isolated from infected individuals who did not have CF was ethanol-soluble. This alcohol-insoluble mucoid from the CF P. aeruginosa could be demonstrated to persist after sequential subcultures of this organism. The relative viscosity and carbohydrate moiety of this insoluble mucoid fraction of P. aeruginosa from individuals with CF differed from that of the non-CF P. aeruginosa soluble mucoid fraction.
Desert Dust Outbreaks in Southern Europe: Contribution to Daily PM10 Concentrations and Short-Term Associations with Mortality and Hospital Admissions

Background: Evidence on the association between short-term exposure to desert dust and health outcomes is controversial. Objectives: We aimed to estimate the short-term effects of particulate matter ≤ 10 μm (PM10) on mortality and hospital admissions in 13 Southern European cities, distinguishing between PM10 originating from the desert and from other sources. Methods: We identified desert dust advection days in multiple Mediterranean areas for 2001–2010 by combining modeling tools, back-trajectories, and satellite data. For each advection day, we estimated PM10 concentrations originating from desert, and computed PM10 from other sources by difference. We fitted city-specific Poisson regression models to estimate the association between PM from different sources (desert and non-desert) and daily mortality and emergency hospitalizations. Finally, we pooled city-specific results in a random-effects meta-analysis. Results: On average, 15% of days were affected by desert dust at ground level (desert PM10 > 0 μg/m3). Most episodes occurred in spring–summer, with increasing gradient of both frequency and intensity north–south and west–east of the Mediterranean basin. We found significant associations of both PM10 concentrations with mortality. Increases of 10 μg/m3 in non-desert and desert PM10 (lag 0–1 days) were associated with increases in natural mortality of 0.55% (95% CI: 0.24, 0.87%) and 0.65% (95% CI: 0.24, 1.06%), respectively. Similar associations were estimated for cardio-respiratory mortality and hospital admissions. Conclusions: PM10 originating from the desert was positively associated with mortality and hospitalizations in Southern Europe. Policy measures should aim at reducing population exposure to anthropogenic airborne particles even in areas with large contribution from desert dust advections.

Integration, Inference, and Management of Spatial Information Using Bayesian Networks: Perceptual Organization

The formalism of Bayesian networks provides a very elegant solution, in a probabilistic framework, to the problem of integrating top-down and bottom-up visual processes, as well serving as a knowledge base. The formalism is modified to handle spatial data, and thus the application of Bayesian networks is extended to visual processing. The modified form is called the perceptual inference network (PIN). The theoretical background of a PIN is presented, and its viability is demonstrated in the context of perceptual organization. Perceptual organization imparts robustness, efficiency, and a qualitative and holistic nature to vision. Thus far, the approaches to the problem of perceptual organization have been purely bottom up, without much top-down knowledge-base influence, and are therefore entirely dependent on the inputs, which are obviously imperfect. The knowledge base, besides coping with such input imperfection, also makes it possible to integrate multiple organizations and form a composite organization hypothesis. The PIN imparts an active inferential and integrating nature to perceptual organization in an elegant probabilistic framework. >
The planctomycetes: emerging models for microbial ecology, evolution and cell biology.

The planctomycetes are an unusual but widely distributed group of budding bacteria which are proving to be of increasing relevance to at least three major areas of research in microbiology: microbial ecology, molecular evolution and cell biology. They constitute one of the phylogenetically distinct major 'phyla' of the domain Bacteria defined using 16S rRNA sequence analysis (Woese, 1987), and form a group so deeply branching it has been proposed as a new bacterial order, Planctomycetales, and family, Planctomycetaceae (Schlesner & Stackebrandt, 1986). Cultured planctomycetes which have been analysed with respect to their cell wall chemistry display the unusual feature of not synthesizing the otherwise universal Bacterial cell wall peptidoglycan; this feature is shared only with the chlamydiae and mycoplasmas among the Bacteria (Konig et al., 1984; Liesack et al., 1986). Planctomycetes also exhibit some unusual molecular features, including short 5S rRNA and, in at least two species, unlinked rrn operon organization (Bomar et al., 1988; Liesack & Stackebrandt, 1989). Gemmata obscuriglobus, a budding bacterium isolated from a freshwater dam in Queensland, Australia (Franzmann & Skerman, 1984), is a member of the order Planctomycetales and is thus within the domain Bacteria, yet possesses a membrane-bounded nuclear body, an organelle hitherto known only in the Eucarya. The unique ultrastructure of this bacterium is of great potential significance to understanding the ways in which eukaryote cell organization may have evolved.
Recognition of historical Greek polytonic scripts using LSTM networks

This paper reports on high-performance Optical Character Recognition (OCR) experiments using Long Short-Term Memory (LSTM) Networks for Greek polytonic script. Even though there are many Greek polytonic manuscripts, the digitization of such documents has not been widely applied, and very limited work has been done on the recognition of such scripts. We have collected a large number of diverse document pages of Greek polytonic scripts in a novel database, called Polyton-DB, containing 15; 689 textlines of synthetic and authentic printed scripts and performed baseline experiments using LSTM Networks. Evaluation results show that the character error rate obtained with LSTM varies from 5.51% to 14.68% (depending on the document) and is better than two well-known OCR engines, namely, Tesseract and ABBYY FineReader.
Surgical treatment of adult idiopathic cavus foot.

To The Editor: We are writing in regard to "Surgical Treatment of Adult Idiopathic Cavus Foot with Plantar Fasciotomy, Naviculocuneiform Arthrodesis, and Cuboid Osteotomy. A Review of Thirty-nine Cases" (2002;84 Suppl 2:S62-9), by Giannini et al. We enjoyed reading the article and were very pleased that 72% of the sixty-nine feet had a good or excellent result. However, we have several questions that we don't believe were addressed in the article. The first concerns the probable causes of idiopathic cavus foot. The authors agree with Ombredanne and Mathieu 1, who reported that cavus feet are secondary to an imbalance of a weak tibialis anterior muscle and an overpowering peroneus longus muscle. The authors believe that this imbalance then causes plantar flexion of the first ray, resulting in a tripod effect. Although we agree with the authors on this point, we are curious as to whether the authors considered other causes that could also contribute to a cavus foot type. Other authors 2 have attributed the deformity to an imbalance …
