Obtaining design knowledge for an underwater robot-swarm for inspecting mooring chains

—We propose a swarming-algorithm that enables a group of autonomous robots to inspect the mooring chains of an oil-platform located in the North Sea. The algorithm, from which an autonomous underwater robot swarm can emerge, is designed to work within the limitations of underwater robotics and communication. Agent-based modelling and simulation (ABMS) has been used to assess the inﬂuence of communication pa- rameters and swarm-size on swarm behaviour in order to obtain knowledge on underwater robot-swarm design. Using the gained knowledge an algorithm is constructed for an autonomous underwater swarm where 160 agents can visit and inspect at least 80% of the mooring chains of a speciﬁc oil-platform, within 24 hours, without losing agents.

In ﬂ uenza Infection and Risk of Acute Myocardial Infarction in England and Wales: A CALIBER Self-Controlled Case Series Study

Background . An association between infections and vascular events has been observed, but the speci ﬁ c effect of in ﬂ uenza and in ﬂ uenza-like illnesses on triggering acute myocardial infarction (AMI) is unclear. Methods . Episodes of ﬁ rst AMI from 1 January 2003 through 31 July 2009 were identi ﬁ ed using linked anonymized electronic medical records from the Myocardial Ischaemia National Audit Project and the General Practice Research Database. Self-controlled case series analysis was used to investigate AMI risks after consultation for acute respiratory infection. Infections were strati ﬁ ed by in ﬂ uenza virus circulation, diagnostic code, and vaccination status to assess whether in ﬂ uenza was more likely than other infections to trigger AMI. Results . Of 22 024 patients with acute coronary syndrome, 11 208 met the criterion of having had their ﬁ rst AMI at the age of ≥ 40 years, and 3927 had also consulted for acute respiratory infection. AMI risks were signi ﬁ cantly raised during days 1 – 3 after acute respiratory infection (incidence ratio, 4.19 [95% con ﬁ dence interval, 3.18 – 5.53], with the effect tapering over time. The effect was greatest in those aged ≥ 80 years ( P = .023).
Research Online Research Online Whole grain consumption and human health: an umbrella review of Whole grain consumption and human health: an umbrella review of observational studies observational studies

Abstract Whole grains have been associated with a number of health benefits. We systematically reviewed existing meta-analyses of observational studies and evaluated the level of evidence for their putative effects based on pre-selected criteria. Of the 23 included studies, we found convincing evidence of an inverse association between whole grain consumption and risk of type-2 diabetes and colorectal cancer; possible evidence of decreased risk of colon cancer and cardiovascular mortality with increased whole grain intake, as well as increased risk of prostate cancer. Limited or insufficient evidence was available for all other outcomes investigated. Overall findings are encouraging for a positive effect of whole grain consumption on certain diseases, especially highly prevalent metabolic diseases, however, uncertainty of some negative associations deserves further attention.

Modeling naturalistic craving, withdrawal, and affect during early nicotine abstinence: a pilot EMA study

Despite the critical role of withdrawal, craving, and positive (PA) and negative affect (NA) in smoking relapse, relatively little is known about the temporal and predictive relationship between these constructs within the first day of abstinence. This pilot study aims to characterize dynamic changes in withdrawal, craving and affect over the course of early abstinence using ecological momentary assessment. Beginning immediately after smoking, moderate and heavy smoking participants (n = 15 per group) responded to hourly surveys assessing craving, withdrawal, NA, and PA. Univariate and multivariate multilevel random coefficient modeling was used to describe the progression of craving, withdrawal/NA and PA and to test correlations between these constructs at the subject-level over the course of early abstinence. Heavy smokers reported greater craving from 1–4 hours of abstinence and greater withdrawal/NA after 3 or more hours as compared to moderate smokers. Level of withdrawal/NA was strongly positively associated with craving, and PA was negatively correlated with craving, however the temporal dynamics of these correlations differed substantially. The association between withdrawal/NA and craving decreased over early abstinence, whereas the reverse was observed for PA. These findings can inform experimental studies of nicotine abstinence as well as their clinical applications to smoking cessation efforts. In particular, these results help to elucidate the role of PA in nicotine abstinence by demonstrating its independent association with nicotine craving over and above withdrawal/NA. If supported by future studies, these findings can refine experimental methods and clinical approaches for smoking cessation.
IN THE GRAVITATIONAL iV-BODY PROBLEM

The gravitational n— body problem is chaotic. Phase trajectories that start very near each other separate rapidly. The rate looks exponential over long times. At any instant, trajectories separated in certain directions move apart rapidly (unstable directions), while those separated in other directions stay about the same (stable directions). Unstable directions lie along eigenvectors that correspond to positive eigenvalues of the matrix of force gradients. The number of positive eigenvalues of that matrix gives the dimensionality of stable regions. This number has been studied numerically in a series of 100—body integrations. It continues to change as long as the integration continues because the matrix changes extremely rapidly. On average, there are about 1 . In unstable directions out of 3n. Issues of dimensionality arise when the tools of ergodic studies are brought to bear on the problem of trajectory separation. A method of estimating the rate of trajectory separation based on matrix descriptions is presented in this note. Severe approximations are required.
Effectiveness of Pharmaceutical Smoking Cessation Aids in a Nationally Representative Cohort of American Smokers

Background: Despite strong efﬁcacy in randomized trials, the population effectiveness of pharmaceutical aids in long-term smoking cessation is lacking, possibly because of confounding (factors that are associated with both pharmaceutical aid use and difﬁculty quitting). Matching techniques in longitudinal studies can remove this confounding bias. Methods: Using the nationally representative Tobacco Use Supplement to the Current Population Survey (TUS-CPS), we assessed the effectiveness of medications to aid quitting among baseline adult smokers who attempted to quit prior to one year of follow-up in two longitudinal studies: 2002–2003 and 2010–2011. Pharmaceutical aid users and nonusers with com-plete data (n ¼ 2129) were matched using propensity score models with 12 potential confounders (age, sex, race-ethnicity, education, smoking intensity, nicotine dependence, previous quit history, self-efﬁcacy to quit, smoke-free homes, survey year, and cessation aid use). Using matched data sets, logistic regression models were ﬁt to assess whether use of any individual pharmaceutical aid increased the proportion of patients who were abstinent for 30 days or more at follow-up. Results: Propensity score matching markedly improved balance on the potential confounders between the pharmaceutical aid use groups. Using matched samples to provide a balanced comparison, there was no evidence that use of varenicline (adjusted risk difference [aRD] ¼ 0.01, 95% conﬁdence interval [CI] ¼ –0.07 to 0.11), bupropion (aRD ¼ 0.02, 95% CI ¼ –0.04 to 0.09), or nicotine replacement (aRD ¼ 0.01, 95% CI ¼ –0.03 to 0.06) increased the probability of 30 days or more smoking abstinence at one-year follow-up. Conclusions:
Electronic Supplementary Information: How aromatic are molecular nanoring? The case of a six-porphyrin nanoring †

Following the computational work of Ref. 1, we have studied four different oxidation states of the six-porphyrin nanoring: neutral, +4, +6, and +12. The molecules have been studied considering not only the isolated belt structure (c-P6, c-P64+, c-P66+, and c-P612+) but also taking into account the encapsulated template and the two phenyl substituents in each porphyrin (c-P6 ·T6, c-P6 ·T64+, c-P6 ·T66+, and c-P6 ·T612+).
Interactive comment on “A comparison of secondary organic aerosol (SOA) yields and composition from ozonolysis of monoterpenes at varying concentrations of NO

The authors reported results from a series of laboratory chamber experiments to evaluate the effect of added NO2 (to ozonolysis experiments) on SOA formation, yields, and compositions for a series of BVOC. Experiments were conducted in a 400L ﬂow through chamber. For a-pinene, the SOA mass appeared to decrease with increasing NO2, possibly a result of increasing reaction between a-pinene and NO3 radicals. The authors noted that b-pinene and carene retained similar mass yields with increasing NO2, while limonene generated more SOA with increasing NO2. Filter samplers were collected from these experiments, and higher molecular weight products were detected in experiments with more NO3 oxidation, suggesting the importance of oligomerization reactions. The research topic would research community is certainly investigating. Unfortunately, there is a mismatch between the experimental and up and the goals of this study, which is a critical weakness of the study. The experiments were conducted by introducing BVOC into the chamber after the oxidant concentrations stabilized. The BVOC concentration was not measured during the experiments. Instead, the BVOC concentration the ﬂask containing it was measured before and after the experiments, and compared to estimates from a model. BVOC yields delMo/delHC). the uncertainties associated uncertainties,

Mixed Convective Hydromagnetic Stagnation Point Flow Nanofluid over Prescribed Surface Heat Flux Mixed Convective Hydromagnetic Stagnation Point Flow ver an Inclined Stretching Plate Prescribed Surface Heat Flux Mixed Convective Hydromagnetic Stagnation Point Flow of n Inclined Stretching Plate with

The aim of this paper is to investigate the two dimensional, nonlinear, steady, mixed convective flow of viscous, incompressible, electrically conducting nanofluid flow over an inclined stretching plate with prescribed heat flux in the presence of uniform transverse magnetic field. The present work concerns with two types of nanofluids such as copper alumina-water nanofluids which analyse the heat transfer due to laminar flow of nanofluids over an inclined stretching plate with angl α with the horizontal. Using appropriate transformations, the governing partial differential equations are transformed into ordinary differential equations with corresponding conditions and which are solved numerically by MATLAB. Numerical solutions are temperature as well as the skin friction coefficient and Nusselt number for different values of pertinent parameters and the physical aspects of the problem are discussed. The numerical results were validated by comparison with previously published results in the literature. It is found that the effect of nanoparticle volume fraction is to increase the heat transfer and hence enhance the thermal boundary layer thickness.

PROJECTIVE MODULES IN THE CATEGORY Os: SELF-DUALITY

Given a parabolic subalgebra lis of a complex, semisimple Lie algebra g, there is a naturally defined category Os of g-modules which includes all the g-modules induced from finite-dimensional lis-modules. This paper treats the question of whether certain projective modules in Os are isomorphic to their dual modules. The projectives in question are the projective covers of those simple modules occurring in the Bocles of generalized Verma modules. Their self-duality is proved in a number of cases, and additional information is obtained on the generalized Verma modules.
ANALYSIS OF DIAGNOSTIC PERFORMANCE OF ALVARADO SCORE AND ULTRASOUND IN PATIENTS SUSPECTED OF HAVING ACUTE APPENDICITIS

: Introduction: Acute appendicitis is a surgical emergency and delay in diagnosis can lead to morbidity of the patient. CT despite of being gold standard investigation carry radiation hazards and risk of cancer. Objective: To evaluate diagnostic reliability of Alvarado score and ultrasound in patients who have suspicion of having acute appendicitis to get to a safe diagnosis without radiation exposure. Material and methods: This cross sectional study was conducted in BHU Daiwal, Khushab during December 2018 to June 2019. Results: Using a cut off value of ≥5.5 Alvarado score resulted in sensitivity of 76%, specificity of 93%, accuracy of 84%, PPV 94%, and NPV 73%. US showed a sensitivity of 66%, specificity of 97.6%, accuracy of 79%, PPV 97% and NPV 67%. There was no difference of accuracy between the two modalities. Using both of these modalities can eliminate the use of CT scan. Conclusion: Using Alvarado score as tool of exclusion and US as 1 st investigation of choice, a case of acute appendicitis is not only diagnosed correctly but also radiation hazards of CT scan can be eliminated.
On the process of cellular division in Escherichia coli: Isolation and characterization of penicillin-binding proteins la, lb, and 3* (affinity chromatography/peptidoglycan biosynthesis/#-lactam

Multiple mutants of Escherichia coli defective in penicillin-bindingp roteins (PBPs) were constructed, and into these strains CoEl plasmids carrying the genes for PBP-la, -lb, or -3 were introduced. From these plasmid-carrying strains, PBP-la and -lb were purified by ampicillin-Sepharose affinity chromatography and PBP-3 by cephalexin-Sepharose affinity chromatography. Improved purification was achieved by dif- ferential elution with NH20H. Purified PBP-lb synthesized murein when added to the membrane fraction of a PBP-lb- defective mutant, which by itself failed to support murein synthesis in vitro. The PBP-lb preparation was able to synthe- size murein from the lipid intermediate extracted with chloro-form/methanol but was unable to utilize UDP4inked precursors for murein synthesis. Murein synthesis was inhibited by van-comysin, ristocetin, moenomycin, and enduracidin, but not by f-lactam antibiotics. The synthesized murein was shown to contain crosslinked muropeptides. Their crosslinking was abolished by action of ,-lactam antibiotics. The PBP-la and -3 preparations showed substantially no activity for murein syn- thesis in the were 100,g/ml and 50 ,g/ml, respectively. Where penicillinase was included, the lipid intermediates were incubated with penicillinase (5 units/ml) for 10 min prior to addition of the PBP-lb fraction. In precursor system I, the preincubated ponB membrane fraction was used as a source of pre- cursors and specific activity of UDP-[14C]GlcNAc was adjusted to 100 ACi/,mol in preincubation mixtures. In precursor system II, the lipid intermediates were synthesized in the absence of penicillin and lipid fractions extracted with chloroform/methanol served as a source of precursors. The subscript B denotes that synthesis of the lipid intermediates was carried out in the presence of benzylpenicillin (100 gg/ml). In I and IIn, 90-100% of radioactivity that remained at the chromatographic origin was recovered as dimers and monomers, and in II 70% was recovered.
Distinct Roles for Signals Relayed through the Common Cytokine Receptor (cid:103) Chain and Interleukin 7 Receptor (cid:97) Chain in Natural T Cell Development

The commitment, differentiation, and expansion of mainstream (cid:97) / (cid:98) T cells during ontogeny depend on the highly controlled interplay of signals relayed by cytokines through their receptors on progenitor cells. The role of cytokines in the development of natural killer (NK)1 (cid:49) natural T cells is less clearly understood. In an approach to define the role of cytokines in the commitment, differentiation, and expansion of NK1 (cid:49) T cells, their development was studied in common cytokine receptor (cid:103) chain ( (cid:103) c) and interleukin (IL)-7 receptor (cid:97) (IL-7R (cid:97) )–deficient mice. These mutations block mainstream (cid:97) / (cid:98) T cell ontogeny at an early prethymocyte stage. Natural T cells do not develop in (cid:103) c-deficient mice; they are absent in the thymus and peripheral lymphoid organs such as the liver and the spleen. In contrast, NK1 (cid:49) T cells develop in IL-7R (cid:97) –deficient mice in the thymus, and they are present in the liver and in the spleen. However, the absolute number of
