High-order harmonic generation spectroscopy by recolliding electron caustics
No full textSpectral focusing of the recolliding electron in high-order harmonic generation driven by two-color fields is shown to be a powerful tool for isolating and enhancing hidden spectral features of the target under study. In previous works we used this technique for probing multi-electron effects in xenon and we compared our experimental results with time-dependent configuration-interaction singles calculations. We demonstrate here that this technique can be exploited for reconstructing the enhancement factor of the xenon giant dipole resonance and we discuss the sensitivity of this method to macroscopic effects. We then extend the technique to argon in order to test the applicability of this procedure to other targets

Fecundity of Sepioteuthis lessoniana (Cephalopoda: Loliginidae), in the Gulf of Mannar Marine Biosphere Reserve
No full textSepioteuthis lessoniana is one of the commercially
important species, showing genetic differences
among its lineages B (Gulf of Mannar) and C (Palk
Bay). This study estimated the average fecundity of
S. lessoniana from lineages B at 1,043 oocytes,
ranging from 308 oocytes in a female, 18.0 cm dorsal
mantle length (DML), (11.8 g ovary weight), to 2,563
oocytes in a female, 34.9 cm DML (70.4 g ovary
weight). Larger females exhibited higher fecundity,
which increased with DML according to the
equation Fecundity=0.2266*DML2.5802. The fecundity-ovary weight relationship followed the equation: Fecundity=21.379+33.131*ovary weight. These
findings contribute to our understanding of S.
lessoniana stocks from lineage B and their management

Proceedings of International Conference On Global Innovations In Computing Technology (ICGICT'14) Adaptive Discriminating Detection for DDoS Attacks from Flash Crowds Using Flow Correlation C o e f f i c i e n t with Collective Feedback
No full textABSTRACT: A Distributed denial of service (DDoS) attack is a most popular and crucial attack in the internet. Its motive is to make a network resource unavailable to the legitimate users. Botnets are commonly the engines behind the attack. In our deep study of the size and organization of current botnets, found that the current attack flowsare usually more similar to each other compared to the flows of flashcrowds In this paper we are concentrating flashcrowd and DDoS there are two steps involved, first it is necessary to differentiate normal traffic and flashcrowd by using Flash Crowd Detection Algorithm. Secon d we ha ve t o di fferentiat e fl ash crowd and DDoS b y usin g Fl ow Correl ati on Coeffi ci ent (FCC). By using this FCC value, algorithm proposed called Adaptive discrimination algorithm is used to detect the DDoS from the flash crowd event. And a s equ en t i al det e ct i on and pac ki n g al gori t h m u sed t o d et ect t he at t a cked pa ck et s and fi l t er i t out .By using above mentioned algorithms we can improve the accuracy in filtering the attacked packets and also the time consummation is reduced

Japan (type locality: Honshu Island), Taiwan, Philippines, Singapore, Malaysia, Vietnam, Australia (Queensland, Victoria) and India (present study).</p> <p> <b>Remarks</b>. The key morphological characteristics of the specimens in identifying them as <i>A. groeningi</i> are as follows: CG11 absent, and anterior margin of carapace with 8–11 spines on both sides of ocular sinus; CG1 to CG10 show the same pattern as in the holotype. The rostrum, triangular ocular plate and distal peduncular segment with cornea at tip are present. The pereopod III dactylus has the base to heel deeply concave, heel to tip with a broadly concave indent and slightly concave indent present at the midpoint of the proximal margin, tip acute, and tip to base smoothly convex. The telson of the male specimen is elongated with the length greater than width and the distal tip rounded with a median indentation. Additional measurements of a male 6.30 mm CL and 7.43 mm CW include: right pereopod I length 4.50 mm, width 5.48 mm; pereopod II length 5.46 mm, pereopod III length 6.87 mm, telson length 2.85 mm, abdominal somite I dorsal length 7.74 mm, abdominal somites II–VI dorsal (combined) length 5.71 mm (Figs. 1, 2).</p> <p> <i>Albunea groeningi</i> is very similar to <i>A. symmysta</i> and <i>A. okinawaensis</i> Osawa & Fujita, 2007 but all three species can be distinguished on the basis of their carapace groove pattern, pereopod I–III shape and telson structure (see Osawa & Fujita 2007). The present specimens of <i>A. groeningi</i> are smaller than many previously reported; males are known up to 14.4 mm CL. The species was previously reported from southern Japan southward to Western Australia and Victoria down to 45.7 m depth (Serene & Umali 1965; Boyko 2002) but was unknown west of this range. In general, albuneids are uncommonly collected and poorly known due to their peculiar burrowing habits (Boyko 2002; Osawa & Fujita 2012). Only three species (<i>A. symmysta, A. occulta, A. thurstoni</i>) were previously reported from the Indian coast (Henderson 1893; Serene & Umali 1965; Subramoniam & Panneerselvam 1985; Roy & Mitra 2010; Marimuthu <i>et al.</i> 2015; Reshmi <i>et al.</i> 2017; Kumar <i>et al.</i> 2018) and <i>A. groeningi</i> is newly recorded from India, specifically from West Bengal on the east coast. Additional surveys and taxonomic studies are required to better ascertain the true diversity of sand crabs in India.</p>Published as part of <i>Yogesh Kumar, J.

C-reactive protein (CRP), interferon gamma-inducible protein 10 (IP-10), and lipopolysaccharide (LPS) are associated with risk of tuberculosis after initiation of antiretroviral therapy in resource-limited settings.
No full textObjectiveThe association between pre-antiretroviral (ART) inflammation and immune activation and risk for incident tuberculosis (TB) after ART initiation among adults is uncertain.DesignNested case-control study (n = 332) within ACTG PEARLS trial of three ART regimens among 1571 HIV-infected, treatment-naïve adults in 9 countries. We compared cases (participants with incident TB diagnosed by 96 weeks) to a random sample of controls (participants who did not develop TB, stratified by country and treatment arm).MethodsWe measured pre-ART C-reactive protein (CRP), EndoCab IgM, ferritin, interferon gamma (IFN-γ), interleukin 6 (IL-6), interferon gamma-inducible protein 10 (IP-10), lipopolysaccharide (LPS), soluble CD14 (sCD14), tumor necrosis factor alpha (TNF-α), and CD4/DR+/38+ and CD8/DR+/38+ T cells. Markers were defined according to established cutoff definitions when available, 75th percentile of measured values when not, and detectable versus undetectable for LPS. Using logistic regression, we measured associations between biomarkers and incident TB, adjusting for age, sex, study site, treatment arm, baseline CD4 and log10 viral load. We assessed the discriminatory value of biomarkers using receiver operating characteristic (ROC) analysis.ResultsSeventy-seven persons (4.9%) developed incident TB during follow-up. Elevated baseline CRP (aOR 3.25, 95% CI: 1.55-6.81) and IP-10 (aOR 1.89, 95% CI: 1.05-3.39), detectable plasma LPS (aOR 2.39, 95% CI: 1.13-5.06), and the established TB risk factors anemia and hypoalbuminemia were independently associated with incident TB. In ROC analysis, CRP, albumin, and LPS improved discrimination only modestly for TB risk when added to baseline routine patient characteristics including CD4 count, body mass index, and prior TB.ConclusionIncident TB occurs commonly after ART initiation. Although associated with higher post-ART TB risk, baseline CRP, IP-10, and LPS add limited value to routine patient characteristics in discriminating who develops active TB. Besides determining ideal cutoffs for these biomarkers, additional biomarkers should be sought that predict TB disease in ART initiators
Interstitial immunostaining and renal outcomes in antineutrophil cytoplasmic antibody-Associated glomerulonephritis
No full textBackground: Immunopathologic features predict renal function at baseline and follow-up in antineutrophil cytoplasmic antibody (ANCA)-Associated glomerulonephritis (GN). The interstitial infiltrate consists predominantly of T lymphocytes, but their pathophysiologic significance is unclear, especially in light of the success of B-cell-directed therapy. Methods: Renal biopsies from 33 patients treated with cyclophosphamide (CYC; n = 17) or rituximab (RTX; n = 16) in the RTX in ANCA-Associated vasculitis (RAVE) trial were classified according to the new ANCA GN classification. T-And B-cell infiltration in the interstitium was assessed by immunostaining for CD3 and CD20. Correlations of clinical and histologic parameters with renal function at set time points were examined. Results: The mean (SD) baseline estimated glomerular filtration rate was 36 (20) mL/min/1.73 m2. ANCA GN class distribution was 46% focal, 33% mixed, 12% sclerotic and 9% crescentic. The interstitial infiltrate consisted of >50% CD3 positive cells in 69% of biopsies, but >50% CD20 positive cells only in 8% of biopsies. In a multiple linear regression model, only baseline glomerular filtration rate (GFR) correlated with GFR at 6, 12, and 18 months. Interstitial B-And T-cell infiltrates had no significant impact on long-Term prognosis, independent of the treatment limb. A differential effect was noted only at 6 months, where a dense CD3 positive infiltrate predicted lower GFR in the RTX group and a CD20 positive infiltrate predicted higher GFR in the CYC group. Conclusions: In ANCA-Associated GN, the interstitial infiltrate contains mainly T lymphocytes. However, it is neither reflecting baseline renal function nor predictive of response to treatment, regardless of the immunosuppression regimen employed
Tunable, Few-Cycle, CEP-Stable Mid-IR Optical Parametric Amplifier for Strong-Field Applications
No full textWe present a robust, three-stage optical parametric amplifier driven by a Ti:Sapphire ultrafast laser system that implements passive carrier-envelope phase stabilization and directly generates five-cycle mid-IR pulses by dispersion compensation. The source is based on potassium titanyl arsenate crystals and exploits intra-pulse difference-frequency seed generation in the mid-IR. This source will be particularly suited for applications in strong-field physics, such as high order harmonic generation and photoelectron spectroscopy
