    Phosphoinositide 3-kinases (PI 3Ks) play a key role in regulation of intracellular signalling and cellular function, including cell proliferation, apoptosis, chemotaxis, membrane trafficking and platelet activation. The PI 3Ks are grouped into three classes on the basis on their structure and in vitro substrate specificity. Class I are activated by a variety of agonists which mediate their effect through tyrosine kinase-linked or G-protein-linked receptors. In vivo class I PI 3Ks seem to preferentially phosphorylate the D3 hydroxyls of the inositol moiety of PtdIns(4,5)P2 to produce PtdIns(3,4,5)P3. However, class II PI 3Ks preferentially phosphorylate the D3 hydroxyl of PtdIns and PtdIns(4)P to produce PtdIns(3)P and PtdIns(3,4)P2, respectively. The late accumulation of PtdIns(3,4)P2 has been suggested to play an important role in irreversible platelet aggregation. In human platelets the class II PI 3K isoform HsC2-PI 3K is activated in an integrin alpha IIb beta 3 + fibrinogen-dependent manner. Class III PI 3Ks phosphorylate PtdIns to produce PtdIns(3)P, which play a crucial role in vesicular trafficking. Recent work has suggested that crosstalk between individual receptors and their downstream signal pathways play a central role in PI 3K signalling responses. In this review, we will concentrate on recent advances regarding the regulation of platelet PI 3Ks.

    Metacaspases are members of the cysteine peptidase family and may be implicated in programmed cell death in plants and lower eukaryotes. These proteases exhibit calcium-dependent activity and specificity for arginine residues at P 1 . In contrast to caspases, they do not require processing or dimerization for activity. Indeed, unprocessed metacaspase-2 of Trypanosoma brucei (TbMCA2) is active; however, it has been shown that cleavages at Lys 55 and Lys 268 increase TbMCA2 hydrolytic activity on synthetic substrates. The processed TbMCA2 comprises 3 polypeptide chains that remain attached by non-covalent bonds. Replacement of Lys 55 and Lys 268 with Gly via site-directed mutagenesis results in non-processed but enzymatically active mutant, TbMCA2 K55/268G. To investigate the importance of this processing for the activity and specificity of TbMCA2, we performed activity assays comparing the non-processed mutant (TbMCA2 K55/268G) with the processed TbMCA2 form. Significant differences between TbMCA2 WT (processed form) and TbMCA2 K55/268G (non-processed form) were observed. Specifically, we verified that although non-processed TbMCA2 is active when assayed with small synthetic substrates, the TbMCA2 form does not exhibit hydrolytic activity on large substrates such as azocasein, while processed TbMCA2 is able to readily digest this protein. Such differences can be relevant for understanding the physiological regulation and function of TbMCA2. Copyright © 2017 Elsevier B.V. All rights reserved.

    Phosphatidylinositide 3-kinases (PI3K) pathway is one of the most important pathway in cells, which plays an important role in proliferation, growth, differentiation and mobility of cells. The aberrant activation of PI3K pathway was exsited in 50%-70% cases of non-small cell lung cancer (NSCLC). As the key point in PI3K pathway, expression of PI3K plays a critical role in activity of the pathway, which is closely related with the initiation and development of NSCLC, furthermore with the response of tumor to target treatment. Our study is to analyze the clinical significance and mechanism of PI3K p110β overexpression in NSCLC. Expression of p110β and other proteins in PI3K pathway were detected by immunohistochemistry in 170 cases of NSCLC. Correlation between expression of p110β and clinicopathological characteristics of patients as well as expression of other proteins in PI3K pathway was analyzed. In 170 NSCLC, overexpression of p110β was found in 41.8% of cases. Correlation between overexpression of p110β and Ki 67 index was significant (P=0.040). No significant difference of p110 expression were observed among different cohorts of gender, age, smoking status, classification, grade and stage (P>0.05). Correlation between expression of p110β and other proteins in PI3K pathway was various, positively correlated with PTEN loss (P0.05). Overexpression of p110β is frequently detected in NSCLC. It is closely related with PTEN loss NSCLC, which shows that it plays an important role in maintaining and developing of tumors driven by PTEN loss. It initiates the proliferation of tumor cells in NSCLC without phosphorylating Akt. PIK3CB mutation is not the major cause of overexpression of p110β. Dysregulation of receptor tyrosine kinases (RTKs) doesn't show potential of increasing p110β level in cancer tissue, furthermore the expression of p110β in tumors with EGFR mutation is lower than in tumors without EGFR mutation.

    We analyse tau to pi pi pi nu /sub tau / decays within the framework of the resonance effective theory of QCD. We have worked out the relevant Lagrangian that describes the axial-vector current hadronization contributing to these processes, and the new coupling constants that arise have been constrained by imposing the asymptotic behaviour of the corresponding spectral function within QCD. Hence we compare the theoretical framework with the experimental data, obtaining a good quality fit from the ALEPH spectral function and branching ratio. We also get values for the mass and on-shell width of the a/sub 1/(1260) resonance, and provide the tau to pi pi pi nu /sub tau / structure functions that have been measured by OPAL and CLEO-II finding an excellent agreement.

    To gain insight into the cellular functions of the mid1-complementing activity (MCA) family proteins, encoding putative Ca²⁺-permeable mechanosensitive channels, we isolated two MCA homologs of tobacco (Nicotiana tabacum) BY-2 cells, named NtMCA1 and NtMCA2. NtMCA1 and NtMCA2 partially complemented the lethality and Ca²⁺ uptake defects of yeast mutants lacking mechanosensitive Ca²⁺ channel components. Furthermore, in yeast cells overexpressing NtMCA1 and NtMCA2, the hypo-osmotic shock-induced Ca²⁺ influx was enhanced. Overexpression of NtMCA1 or NtMCA2 in BY-2 cells enhanced Ca²⁺ uptake, and significantly alleviated growth inhibition under Ca²⁺ limitation. NtMCA1-overexpressing BY-2 cells showed higher sensitivity to hypo-osmotic shock than control cells, and induced the expression of the touch-inducible gene, NtERF4. We found that both NtMCA1-GFP and NtMCA2-GFP were localized at the plasma membrane and its interface with the cell wall, Hechtian strands, and at the cell plate and perinuclear vesicles of dividing cells. NtMCA2 transcript levels fluctuated during the cell cycle and were highest at the G1 phase. These results suggest that NtMCA1 and NtMCA2 play roles in Ca²⁺-dependent cell proliferation and mechanical stress-induced gene expression in BY-2 cells, by regulating the Ca²⁺ influx through the plasma membrane.

    Twenty-seven patients with minor completed and major stroke in the chronic stage underwent superficial temporal artery-middle cerebral artery (STA-MCA) anastomosis. The regional cerebral blood flow (rCBF), using inhalation of stable xenon and computed tomographic scanning (Xe s CT-CBF study), and the mode of transit time (MTT) in the MCA territory using intra-arterial digital aortography were measured. Activated rCBF and MTT was measured 20 minutes after the administration of acetazolamide (10 mg/kg) in 14 patients. Nineteen of the 23 patients with minor stroke (Group 1) showed immediate improvement in their neurological state within a few days of the operation, while four patients with minor stroke (Group 2) and four patients with major stroke (Group 3) showed no improvement. Based on the rCBF obtained with the Xe s CT-CBF study, affected side rCBF/unaffected side rCBF and %f [(peak DSA number/affected side MTT)/(peak DSA number/unaffected side MTT)] were compared. There was a significant positive correlation. Affected side MTT in Group 1 was 6.41±1.16 sec, preoperatively, and significantly decreased to 5.13±0.91 sec after the operation. On the other hand, preoperative MTT in Group 2 was 4.40±0.81 sec and 4.76±0.89 sec, postoperatively. Preoperative %f in Group 1 was 0.514±0.143 and significantly increased to 0.739±0.154, postoperatively. Group 2 showed no change. Vasodilatory capacity with acetazolamide showed a marked improvement in Group 1, postoperativery. Our study indicated that if MTT is moderately lengthened, %f is moderately decreased, and vasodilatory capacity is impaired, in patients with minor ischemic stroke will benefit from STA-MCA anastomosis.

    We report a study of the suppressed $B^{-}\\to DK^-\\pi^+\\pi^-$ and favored $B^-\\to D\\pi^-\\pi^+\\pi^-$ decays, where the neutral $D$ meson is detected through its decays to the $K^{\\mp}\\pi^{\\pm}$ and $CP$-even $K^+K^-$ and $\\pi^+\\pi^-$ final states. The measurement is carried out using a proton-proton collision data sample collected by the LHCb experiment, corresponding to an integrated luminosity of 3.0 fb$^{-1}$. We observe the first significant signals in the $CP$-even final states of the $D$ meson for both the suppressed $B^{-}\\to DK^-\\pi^+\\pi^-$ and favored $B^-\\to D\\pi^-\\pi^+\\pi^-$ modes, as well as in the doubly Cabibbo-suppressed $D\\to K^+\\pi^-$ final state of the $B^-\\to D\\pi^-\\pi^+\\pi^-$ decay. Evidence for the ADS suppressed decay $B^{-}\\to DK^-\\pi^+\\pi^-$, with $D\\to K^+\\pi^-$, is also presented. From the observed yields in the $B^{-}\\to DK^-\\pi^+\\pi^-$, $B^-\\to D\\pi^-\\pi^+\\pi^-$ and their charge conjugate decay modes, we measure the value of the weak phase to be $\\gamma=(74^{+20}_{-18})^{\\rm o}$.

    Decompressive hemicraniectomy (DHC) reduces mortality and improves outcome after malignant middle cerebral artery (MCA) infarction but leaves a high number of survivors severely disabled. Attitudes among physicians toward the degree of disability that is considered acceptable and the impact of aphasia may play a major role in treatment decisions. DESTINY-S is a multicenter, international, cross-sectional survey among 1,860 physicians potentially involved in the treatment of malignant MCA infarction. Questions concerned the grade of disability, the hemisphere of the stroke, and the preferred treatment for malignant MCA infarction. mRS scores of 3 or better were considered acceptable by the majority of respondents (79.3%). Only few considered a mRS score of 5 still acceptable (5.8%). A mRS score of 4 was considered acceptable by 38.0%. Involved hemisphere (dominant vs. non-dominant) was considered a major clinical symptom influencing treatment decisions in 47.7% of respondents, also reflected by significantly different rates for DHC as preferred treatment in dominant versus non-dominant hemispheric infarction (46.9 vs. 72.9%). Significant differences in acceptable disability and treatment decisions were found among geographic regions, medical specialties, and respondents with different work experiences. Little consensus exists among physicians regarding acceptable outcome and therapeutic management after malignant MCA infarction, and physician's recommendations do not correlate with available evidence. We advocate for a decision-making process that balances scientific evidence, patient preference, and clinical expertise.

    The MicroNOMAD-MCA is a gamma spectrometer for radiation exposure measurement using matrix respond method. The equipment used NAI detector to produced pulse spectrum and then covert to quantities of dosimeter by a computer program. Performance evaluation of the MCA-MicroNOMAD has been done to evaluate the reliability and accuracy of the measurement result. The evaluation was done by comparison test with standard survey meter. Measurement of gamma radiation was performed in the experimental Hall, Operation Hall of the RSG-GAS and outside of reactor building with 15 MW reactor power. The gamma radiation exposure measurement result in the Experimental Hall using the MicroNOMAD MCA and Ion Chamber survey meter are 92,4 x 10 exp 6 rad/hour and (62 ∼ 88) x 10 exp 6 rad/hour, respectively. The gamma radiation exposure in the Operation Hall using the MicroNOMAD MCA and Ion Chamber are 165,4 x 10 exp 6 rad/hour and (167 ∼ 194) x 10 exp 6 rad/hour, respectively. By means of this result it can concluded that the reading error of the MicroNOMAD MCA with standard survey meter is small enough. Beside the point the MicroNOMAD MCA has a good performance for gamma radiation measurement in the energy range of 0,2 - 9 MeV

    In 1981 a small, battery-operated multichannel analyzer (MCA) prototype developed at Los Alamos National Laboratory was delivered to the International Atomic Energy Agency (IAEA). The intent was to produce an instrument for inspector (nonscientist) use. Automated measurement programs were built into the MCA. An enhanced, commercially produced MCA is now available, which was patterned after and is software compatible with the prototype. After an extensive review of the hardware and software of the available portable MCAs, the IAEA has chosen this MCA to be used by IAEA inspectors throughout the world. Inspectors from the EURATOM Directorate of Safeguards are also using these MCAs in inspections throughout Europe. While this MCA's portability and programmability make it ideally suited for infield applications, its powerful built-in intelligence and communications protocol make it a strong candidate for distributed data acquisition and control systems. The user-instrument interface philosophy is so easy to use that in domestic and international training schools, the operators manual is not used

    and Complete (AC, Accurate but Incomplete (AI, Inaccurate (IN, and Absent (AB concepts, overall main concept score (MC, as well as AC per minute, were used to analyze each language samples. A pair-sample t-test was conducted to evaluate the different performance between the aphasic and control groups. External validity of the TM-MCA was established by conducting Pearson product-moment correlations between the TM-MCA measures and the overall aphasia score in the Concise Chinese Aphasia Test (CCAT; Chung, Li, & Chang, 2003 and Linguistic Communication Measure adapted for Taiwanese Mandarin (TM-LCM. Results and Discussion The results suggested that both age and education affected the oral discourse performance in our normal subjects. Significant differences on the measures in TM-MCA were noted between the normal and aphasic groups. It was also found that overall aphasia severity, as reflected by the CCAT, affected the picture description performances. Finally, significant correlations between most TM-MCA measures and related TM-LCM indices were noted. In conclusion, the TM-MCA is culturally appropriate to the Taiwanese Mandarin population as a supplement to existing standardized aphasia batteries, which typically do not include comprehensive and objective evaluation of oral discourse.

    A data processing system has been designed for use with the indigenous 4-K MCA. It consists of Micro 2200 - a programmable calculator, Micro data Interface (MDI), floppy disk attachment to Micro and a Data Interface specially designed for the transfer of data from MCA to Micro 2200 and for reverse transfer. This complete system enables one to transfer the spectrum from MCA, and to carry out desired spectrum analysis. The system has been used for routine analysis of energy dispersive XRF spectra. The report describes the hardware design of the Data Interface and the software of data transfer and standard spectrum analysis routines. Listing of Micro programmes for transfer and analysis are also given in the report. (author)

    The operating software of the PHAST PC-MCA Card provides powerful hardware support and data analysis features. Spectrum stabilisation is supported. A periodic spectrum saving option helps recovery of usable data in case of power failure. This feature can also be used for decay studies. Spectra acquired in several other types of MCA cards may be read for offline analysis. Non-linear least square fitting of the peaks in the entire spectrum with exponential tailed model is possible in a single operation. Nuclides may be identified and activity determined by matching energies with the gamma energy library of the program. Two component decay analysis at multiple energies is possible. (author)

    Full Text Available Abstract Background The intracranial localization of large artery disease is recognized as the main cause of ischemic stroke in the world, considering all countries, although its global burden is widely underestimated. Indeed it has been reported more frequently in Asians and African-American people, but the finding of intracranial stenosis as a cause of ischemic stroke is relatively common also in Caucasians. The prognosis of patients with stroke due to intracranial steno-occlusion is strictly dependent on the time of recanalization. Moreover, the course of the vessel involvement is highly dynamic in both directions, improvement or worsening, although several data are derived from the atherosclerotic subtype, compared to other causes. Case description We report the clinical, neurosonological and neuroradiological findings of a young woman, who came to our Stroke Unit because of the abrupt onset of aphasia during her work. An urgent neurosonological examination showed a left M1 MCA stenosis, congruent with the presenting symptoms; magnetic resonance imaging confirmed this finding and identified an acute ischemic lesion on the left MCA territory. The past history of the patient was significant only for a hyperinsulinemic condition, treated with metformine, and a mild overweight. At this time a selective cerebral angiography was not performed because of the patient refusal and she was discharged on antiplatelet and lipid-lowering therapy, having failed to identify autoimmune or inflammatory diseases. Within 1 month, she went back to our attention because of the recurrence of aphasia, lasting about ten minutes. Neuroimaging findings were unchanged, but the patient accepted to undergo a selective cerebral angiography, which showed a mild left distal M1 MCA stenosis. During the follow-up the patient did not experienced any recurrence, but a routine neurosonological examination found an unexpected evolution of the known MCA stenosis, i.e. left M1 MCA

    Background Hepatocellular carcinoma (HCC) is the fifth most common fatal cancer and an important healthcare problem worldwide. There are many studies describing the prognostic and predictive effects of epidermal growth factor receptor 2 (c-erb-B2) and epidermal growth factor receptor 1 (EGFR), transmembrane tyrosine kinases that influence cell growth and proliferation in many tumors. Objectives The current study aimed to investigate the expression levels of c-erb-B2, EGFR, PTEN, mTOR, PI3K, p27, and ERCC1 in hepatocellular carcinoma (HCC) and their correlation with other clinicopathologic features. Patients and Methods Fifty HCC cases were stained immunohistochemically with these markers. Correlations between the markers and clinicopathologic characteristics and survival rates were analyzed. Results No membranous c-erb-B2 staining was seen, whereas cytoplasmic positivity was present in 92% of HCC samples, membranous EGFR was observed in 40%, PI3K was found in all samples, and mTOR was seen in 30%, whereas reduced or absent PTEN expression was observed in 56% of samples and loss of p27 was seen in 92% of the cases. c-erb-B2 and mTOR overexpression, as well as reduced expression of p27, all correlated with multiple tumors (P = 0.041, P < 0.001, and P < 0.001, respectively). P27 loss, and mTOR and EGFR positivity were significantly correlated with AFP (P = 0.047, P = 0.004, and P = 0.008, respectively). Angiolymphatic invasion was more commonly seen in EGFR- and ERCC1-positive cases (P = 0.003 and P = 0.005). EGFR was also correlated with histological grade (P = 0.039). No significant correlations were found among PTEN , PI3K, and the clinicopathological parameters. Disease-free or overall survival rates showed significant differences among therapy modalities, AFP levels, angiolymphatic or lymph node invasions, and ERCC1 and p27 expression levels (P < 0.05). Conclusions c-erb-B2, EGFR, mTOR, ERCC1 overexpression levels, and loss of p27 may play roles in

    To determine the differential protein expression of biomarkers FGFR3, PI3K (subunits PI3Kp110α, PI3KClassIII, PI3Kp85), AKT, p21Waf1/Cip1 and cyclins D1 and D3 in T1 bladder cancer versus healthy tissue and to study their potential role as early recurrence markers. This is a prospective study that employed a total of 67 tissue samples (55 cases of T1 bladder tumours that underwent transurethral resection and 12 cases of adjacent healthy mucosa). The protein expression levels were assessed using Western blot, and the means and percentages were compared using Student's t-test and the chi-squared test. The survival analysis was conducted using the Kaplan-Meier method and the log-rank test. Greater protein expression was detected for FGFR3, PI3Kp110α, PI3KClassIII, cyclins D1 and D3 and p21Waf1/Cip1 in the tumour tissue than in the healthy mucosa. However, these differences were not significant for PI3Kp85 and AKT. We observed statistically significant correlations between early recurrence and PI3Kp110α, PI3KClassIII, PI3Kp85 and AKT (P=.003, P=.045, P=.050 and P=.028, respectively), between the tumour type (primary vs. recurrence) and cyclin D3 (P=.001), between the tumour size and FGFR3 (P=.035) and between multifocality and cyclin D1 (P=.039). The survival analysis selected FGFR3 (P=.024), PI3Kp110α (P=.014), PI3KClassIII (P=.042) and AKT (P=.008) as markers of early-recurrence-free survival. There is an increase in protein expression levels in bladder tumour tissue. The overexpression of FGFR3, PI3Kp110α, PI3KClassIII and AKT is associated with increased early-recurrence-free survival for patients with T1 bladder tumours. Copyright © 2016 AEU.

    2015-04-01

    Plant-scale filtration experiments with molten aluminum have been carried out with two different types of 10 × 10 × 2 in, 30 ppi ceramic foam filters. The filters were produced in the same production line where the only difference was the composition of the ceramic slurry used for the filter production. The inclusion contents in the aluminum melt before and after the filters were measured with two constantly running liquid metal cleanliness analyzer (LiMCA) II units. Three methods for analyzing the recorded data are presented. A significant difference in the filtration performance as function of time was found when settling of inclusions in the melt was taken into account. Statistical treatment of the time dependent LiMCA II data was performed.

    High wheel tractor applications of 4-methoxycinnamaldehyde (MCA)-coated corn granules ('grits') were conducted in Ruski Krstur (Serbia) in summer 2001 in a 5 ha corn field. Grits are a by-product after corn is harvested and separated from the cob and used as a carrier medium to disseminate MCA into the corn field. MCA is a kairomone mimic derived form Cucurbita maxima (Duchesne) used to disrupt orientation of Diabrotica virgifera virgifera LeConte towards different MCA and pheromone baited traps. The ultimate goal is to investigate the use of MCA as a mating disruptant. MCA was dissolved in an organic solvent and mixed in a cement machine with the grits. Grits were applied at rates of 17.39, 17.1 and 12.45 kg/ha on July 4th, July 19th and August 3rd. Before the impact of MCA as a disruptant can be addressed, the distribution patterns of MCA coated grits have to be thoroughly investigated. They were evaluated by counting girts deposited in 16 or 20 plastic dishes of 30-cm diameter positioned along 2 rows through the field directly after the grit application by tractor. Additionally, grits deposited on corn plant surface such as leaves, leaf axils and corn cobs were counted. Total number of grits collected in plastic dishes revealed even application rates at the first and second application but not on the third application date. Number of grits collected on plant surfaces were significantly different from each other regarding each application date. Altogether, grit distribution in the dishes as well as on the plant surface was variable. However, distribution patterns achieved so far hold promise to disseminate MCA coated grits into corn fields for orientation disruption or mating disruption of D. virgifera virgifera.

  5. Use of multiple correspondence analysis (MCA) to identify interactive meteorological conditions affecting relative throughfall

    Forest canopies alter rainfall reaching the surface by redistributing it as throughfall. Throughfall supplies water and nutrients to a variety of ecohydrological components (soil microbial communities, stream water discharge/chemistry, and stormflow pathways) and is controlled by canopy structural interactions with meteorological conditions across temporal scales. This work introduces and applies multiple correspondence analyses (MCAs) to a range of meteorological thresholds (median intensity, median absolute deviation (MAD) of intensity, median wind-driven droplet inclination angle, and MAD of wind speed) for an example throughfall problem: identification of interacting storm conditions corresponding to temporal concentration in relative throughfall beyond the median observation (⩾73% of rain). MCA results from the example show that equalling or exceeding rain intensity thresholds (median and MAD) corresponded with temporal concentration of relative throughfall across all storms. Under these intensity conditions, two wind mechanisms produced significant correspondences: (1) high, steady wind-driven droplet inclination angles increased surface wetting; and (2) sporadic winds shook entrained droplets from surfaces. A discussion is provided showing that these example MCA findings agree well with previous work relying on more historically common methods (e.g., multiple regression and analytical models). Meteorological threshold correspondences to temporal concentration of relative throughfall at our site may be a function of heavy Tillandsia usneoides coverage. Applications of MCA within other forests may provide useful insights to how temporal throughfall dynamics are affected for drainage pathways dependent on different structures (leaves, twigs, branches, etc.).

    The purpose of this study was to objectively assess the efficacy of superficial temporal artery to middle cerebral artery (STA-MCA) bypass surgery using Technetium (Tc)-99m-ethyl cysteinate dimer (ECD) single photon emission computed tomography (SPECT) in patients who underwent STA-MCA bypass surgery. Brain perfusion SPECT images obtained at baseline and after the administration of acetazolamide were reconstructed using statistical parametric mapping in 23 patients, both before and after STA-MCA bypass surgery. The clinical outcomes of the surgery were also recorded and compared with the hemodynamic changes. A voxel with an uncorrected p-value of less than 0.001 was considered to be statistically significant. SPECT images of the territory supplied by the bypass graft showed an increase in both cerebrovascular flow and reserve at baseline, and the increase was significantly higher following the administration of acetazolamide. All patients showed improvement of clinical symptoms and increased blood flow to the left temporal, parietal, and frontal cortices as well as the thalamus. Brain SPECT effectively and objectively demonstrated the improved outcomes of STA-MCA bypass surgery, and thus may be used in postoperative analyses

    The hepato-biliary scan with sup(99m)Tc-pyridoxylidene Isoleucine (sup(99m)Tc-PI) was able to demonstrate the biliary system much more clearly than that using usual radiopharmaceuticals such as /sup 131/I-BSP of /sup 131/I-Rose Bengal. The hepato-biliary scan with sup(99m)Tc-PI demonstrated the hepatobiliary system more clearly than DIC in 47.6% of all cases studied. Especially the demonstration of changes of intra-hepatic biliary tree in cases with intra-hepatic gall stone and cholangiocarcinoma was quite superior to DIC, although there was somewhat difficulty in getting information about the right hepatic duct. For the diagnosis of gall stone in the gall bladder, DIC was more suitable than sup(99m)Tc-PI hepatobiliary scan. The sup(99m)Tc-PI hepato-biliary scan was able to demonstrate the biliary system even in cases having moderate jaundice, in which cases DIC could not demonstrate the biliary system. This sup(99m)Tc-PI hepato-biliary scan was proved to be useful in determing a certain cause of defects shown on the conventional liver scan. No side effect was noticed in this series of the study.

    Full Text Available We report a case of complex large middle cerebral artery (MCA bifurcation aneurysm that ruptured during dissection from the very adherent MCA branches but was successfully clipped and the MCA bifurcation reconstructed using 4 Yasargill clips. Through a right pterional craniotomy the sylvian fissure was largely opened as to allow enough workspace for clipping the aneurysm and placing a temporary clip on M1. The pacient recovered very well after surgery and was discharged after 1 week with no neurological deficit. Complex MCA bifurcation aneurysms can be safely reconstructed using regular clips, without the need of using fenestrated clips or complex by-pass procedures.

We measure {Beta}(B{sup 0} {yields} {pi}{sup {+-}}) = (28.9 {+-} 5.4 {+-} 4.3) x 10{sup 6}, and find no evidence for the presence of any other decay mode in the {pi}{sup +}{pi}{sup -} {pi}{sup 0} Dalitz plot. Upper limits are determined for the branching fractions of B{sup 0} {yields} {sup 0}{pi}{sup 0}, non-resonant B{sup 0} decays to {pi}{sup +}{pi}{sup -} {pi}{sup 0} and of several discrete regions of {pi}{sup +}{pi}{sup -} {pi}{sup 0} phase-space. We also measure the direct CP-violating asymmetry between the rates of untagged {sup +}{pi}{sup -} and {sup -}{pi}{sup +}, finding no significant evidence for an effect.

    2017-07-01

    Multicriteria analysis (MCA) is a decision-making tool applied to a wide range of environmental management problems, including renewable energy planning and management. An interesting field of application of MCA is the evaluation and analysis of the conflicting aspects of hydropower (HP) exploitation, affecting the three pillars of sustainability and involving several different stakeholders. The present study was aimed at reviewing the state of the art of MCA applications to sustainable hydropower production and related decision-making problems, based on a detailed analysis of the scientific papers published over the last 15 years on this topic. The papers were analysed and compared, focusing on the specific features of the MCA methods applied in the described case studies, highlighting the general aspects of the MCA application (purpose, spatial scale, software used, stakeholders, etc.) and the specific operational/technical features of the selected MCA technique (methodology, criteria, evaluation, approach, sensitivity, etc.). Some specific limitations of the analysed case studies were identified and a set of "quality indexes" of an exhaustive MCA application were suggested as potential improvements for more effectively support decision-making processes in sustainable HP planning and management problems.

    This book documents the history of pi from the dawn of mathematical time to the present. One of the beauties of the literature on pi is that it allows for the inclusion of very modern, yet accessible, mathematics. The articles on pi collected herein include selections from the mathematical and computational literature over four millennia, a variety of historical studies on the cultural significance of the number, and an assortment of anecdotal, fanciful, and simply amusing pieces. For this new edition, the authors have updated the original material while adding new material of historical and cultural interest. There is a substantial exposition of the recent history of the computation of digits of pi, a discussion of the normality of the distribution of the digits, new translations of works by Viete and Huygen, as well as Kaplansky's never-before-published "Song of Pi." From the reviews of earlier editions: "Few mathematics books serve a wider potential readership than does a source book and this particular on...

    Various in-situ gamma-spectroscopy applications need a versatile, multi-purpose, portable multi-channel analyzer (MCA). Recently, Canberra has introduced the Inspector-2000 for this purpose. It uses digital signal processing (DSP) technology and weighs only about 1.2 kg. It also supports CdTe, NaI and Ge detectors. Due to its use of DSP technology, the Inspector-2000 also provides a longer battery life, a better detector resolution and a better temperature stability than most portable MCAs. A short description of the Inspector-2000 MCA is included and its performance characteristics compared to an analog MCA. (author)

    is based on the fact that when using MCA as a decision-support tool, questions often arise about the weighting (or prioritising) of the included criteria. This part of the MCA is seen as the most subjective part and could give reasons for discussion among the decision makers or stakeholders. Furthermore......This paper discusses the concept of using rank variation concerning the stake-holder prioritising of importance criteria for exploring the sensitivity of criteria weights in multi-criteria analysis (MCA). Thereby the robustness of the MCA-based decision support can be tested. The analysis described......, the relative weights can make a large difference in the resulting assessment of alternatives [1]. Therefore it is highly relevant to introduce a procedure for estimating the importance of criteria weights. This paper proposes a methodology for estimating the robustness of weights used in additive utility...

    We propose an experiment at the LHC with leading neutron production. The latter can be used to extract from it the total {pi}{sup +} p cross-sections. With two leading neutrons we can get access to the total {pi}{sup +}{pi}{sup +} cross-sections. In this note we give some estimates and discuss related problems and prospects. (orig.)

    Decays of baryon resonances in the second and the third resonance region into N{pi}{sup 0}{pi}{sup 0} are studied by photoproduction of two neutral pions off protons. Partial decay widths of N* and {delta}* resonances decaying into {delta}(1232){pi}, N({pi}{pi}){sub S}, N(1440)P{sub 11}{pi}, and N(1520)D{sub 13}{pi} are determined in a partial wave analysis of this data and of data from other reactions. Several partial decay widths were not known before. Interesting decay patterns are observed which are not even qualitatively reproduced by quark model calculations. In the second resonance region, decays into {delta}(1232){pi} dominate clearly. The N({pi}{pi}){sub S}-wave provides a significant contribution to the cross section, especially in the third resonance region. The P{sub 13}(1720) properties found here are at clear variance to PDG values.

  18. Production of {pi}{sup 0}{pi}{sup 0} and {pi}{sup +}{pi}{sup +} pairs in proton-proton collisions

    The {pi}{sup 0}{pi}{sup 0} production in proton-proton collisions has been measured in the energy range from threshold up to 1.3 GeV using the WASA 4{pi} detector setup with an internal pellet target at the CELSIUS storage ring in Uppsala. In addition the {pi}{sup +}{pi}{sup +} production has been measured at an incident energy of 1.1 GeV. The {pi}{sup 0}{pi}{sup 0} and {pi}{sup +}{pi}{sup +} data taken at WASA constitute the first exclusively measured samples of solid statistics in the considered energy range. Total and differential cross sections for the pp{yields}pp{pi}{sup 0}{pi}{sup 0} and pp{yields}nn{pi}{sup +}{pi}{sup +} reactions are systematically compared to the Valencia model predictions. At incident energies close to threshold, i.e. up to 0.9 GeV, the {pi}{sup 0}{pi}{sup 0} data can be successfully explained by excitation and decay of the Roper resonance. Its direct decay into the N{sigma} channel is found to be by far the dominating two-pion decay process. in favor of a monopole excitation of the Roper resonance. At energy T{sub p}>1 GeV, i.e. in the energy region, which is beyond the Roper excitation but at the onset of {delta}{delta} excitation, a behavior is observed which is different from the theoretical prediction both in differential and total cross sections. The differential cross sections for {pi}{sup 0}{pi}{sup 0} channel in the {delta}{delta} region can be described, if the special configuration ({delta}{delta}){sub 0} is assumed. Moreover, the {pi}{sup 0}{pi}{sup 0} data exhibit a small systematic low-mass enhancement in the {pi}{sup 0}{pi}{sup 0} invariant mass spectrum. The total pp{pi}{sup 0}{pi}{sup 0} cross sections fall behind theoretical predictions, whereas the nn{pi}{sup +}{pi}{sup +} cross section is a factor of five larger that expected. A model-unconstrained isospin decomposition of the total cross sections points to a s-channel-like energy dependence of the Roper excitation as well as to a significant contribution of an

    The background and purpose of this study was to elucidate whether the effects of alteplase differ with occlusion site of the middle cerebral artery (MCA). An exploratory analysis was made of 57 patients enrolled on the Japan Alteplase Clinical Trial II (J-ACT II). The residual vessel length (mm), determined on pretreatment MR angiography (MRA), was used to reflect the occluded site. The proportions of patients with valid recanalization (modified Mori grade 2-3) at 6 and 24 hours, and a favorable outcome (modified Rankin scale 0-1 at 3 months) were compared between the groups dichotomized according to their lengths of residual vessel. Multiple logistic regression models were generated to elucidate the predictors of valid recanalization and a favorable outcome. Receiver operating characteristic (ROC) analysis revealed that 5 mm was the practical cutoff length for the dichotomization. In patients with M1 length <5 mm (n=12), the frequencies of valid recanalization at 6/24 hours (16.6%/25.0%) were significantly low compared with those (62.2%/82.2%) of 45 patients with a residual M1 length of ≥5 mm and M2 occlusions (p=0.008 for 6 hours, p<0.001 for 24 hours). The proportion of a favorable outcome was also small in patients with M1 length <5 mm (8.3%), as compared to the others (57.8%, p=0.004). In logistic regression models, the site of MCA occlusion (<5 mm) was the significant predictor of valid recanalization at 6/24 hours and of a favorable outcome. In patients with acute MCA occlusion, residual vessel length <5 mm on MRA can identify poor responders. (author)

    The reactions gamma gamma -> pi^+pi^-pi^+pi^- and gamma gamma -> pi^+pi^0pi^-pi^0 are studied with the L3 detector at LEP in a data sample collected at centre-of-mass energies from 161GeV to 209GeV with a total integrated luminosity of 698/pb. A spin-parity-helicity analysis of the rho^0 rho^0 and rho^+ rho^- systems for two-photon centre-of-mass energies between 1GeV and 3GeV shows the dominance of the spin-parity state 2+ with helicity 2. The contribution of 0+ and 0- spin-parity states is also observed, whereas contributions of 2- states and of a state with spin-parity 2+ and zero helicity are found to be negligible.

    The COMPASS experiment at CERN has collected a large data sample of 50 million diffractively produced $\\pi^-\\pi^+\\pi^-$ events using a $190\\,$GeV$/c$ negatively charged hadron beam. The partial-wave analysis (PWA) of these high-precision data reveals previously unseen details. The PWA, which is currently limited by systematic uncertainties, is based on an isobar model, where multi-particle decays are described as subsequent two-body decays and where a prior-knowledge parametrization for the intermediate two-pion resonances has to be assumed -- usually a Breit-Wigner amplitude -- thus increasing systematic uncertainties, due to the concrete choice of the parametrization. We present a novel method, which allows to extract isobar amplitudes directly from the data in a less biased way. The focus lies on the scalar $\\pi^+\\pi^-$ subsystem, where a previous analysis found a signal for a new axial-vector state $a_1(1420)$ decaying into $f_0(980)\\pi$.

    The TSA Systems, Ltd., MCA465 is hand-portable, low resolution, gamma-ray instrument for confirming special nuclear materials (SNM) and related applications. The instrument evolved from earlier TSA Systems hand-held instruments, and, since its inception in 1991, it has been undergoing cycles of evaluation and then repair or redesign to correct problems. Through the efforts of Los Alamos, Rocky Flats, and TSA Systems, the MCA465 now has achieved commendable progress toward achieving quality performance as a rapid confirmation tool for SNM

    Evidence is presented for the decay $B_c+\\rightarrow J/\\psi 3\\pi^+2\\pi^-$ using proton-proton collision data, corresponding to an integrated luminosity of 3fb$^{-1}$, collected with the LHCb detector. A signal yield of $32\\pm8$ decays is found with a significance of 4.5 standard deviations. The ratio of the branching fraction of the $B_c^+\\rightarrow J/\\psi 3\\pi^+ 2\\pi^-$ decay to that of the $B_c^+ \\rightarrow J/\\psi \\pi^+$ decay is measured to be $$ \\frac{Br (B_c^+ \\rightarrow J/\\psi 3\\pi^+2\\pi^)}{Br (B_c^+ \\rightarrow J/\\psi \\pi^+)} = 1.74\\pm0.44\\pm0.24, $$ where the first uncertainty is statistical and the second is systematic.

  9. Design and implementation of an MCA card with double ADC for nuclear radiation analysis

    International Nuclear Information System (INIS)

    Razanabololona, V.H.

    2001-01-01

    The rapid development of technology has triggered several interesting trends in nuclear instrumentation. In particular, the introduction of add-on cards that can serve as multichannel analyzer and offer adequate performance for most of the nuclear applications. The purpose of this thesis has been the design of a multichannel analyser inserted into microcomputer. The originality of this prototype MCA card with its innovative concept is the use of two analog digital converters or ADC of which the objective is to reduce to minima the lost of pulses during the acquisition and the signals processing. The first ADC works as the main converter (or master) and the second ADC the slave converter. The first ADC begins the first signals acquisition, while it will be busy for the processing, the second ADC continues the acquisition, thus there will be no lost pulses or precisely lost of pulses will be reduced to minima.The three main points for a multichannel analyzer will be studied such a the pile-up, the differential non-linearity or 'DNL' and the dead time. In the first part of this thesis the function of the MCA has been described and the different roles of the composed modules have been developed. In the second part, spectra analysis has been done with the MCA prototype as well the comparison with other MCAs such as MCAs S100, TISA, MCA35+, and the Inspector. [fr

    The large class sizes of first-year chemistry labs makes it challenging to provide students with hands-on access to instrumentation because the number of students typically far exceeds the number of research-grade instruments available to collect data. Multifunctional chemical analysis (MCA) systems provide a viable alternative for large-scale…

    The analysis of B{sup {+-}} {yields} pi{sup {+-}}{pi}{sup 0} and B{sup {+-}} {yields} K{sup {+-}}{pi}{sup 0} modes has been done with a sample of 227 millions of B pairs corresponding to 205 fb{sup -1} of data collected between october 1999 and july 2004 with the BABAR detector. The branching ratios and CP asymmetries obtained are: Br({pi}{pi}{sup 0}) = (5.57 {+-} 0.60 {+-} 0.33)*10{sup -6}; Br(K{pi}{sup 0}) (11.50 {+-} 0.65 {+-} 0.57)*10{sup -6}; A({pi}{pi}{sup 0}) = (-0.007 {+-} 0.104 {+-} 0.023); and A(K{pi}{sup 0}) = (0.066 {+-} 0.055 {+-} 0.010). The constraints on the angle alpha of the unitarity triangle have been derived from the isospin analysis of B {yields} {pi}{pi} modes. The isospin symmetry has also been used to relate B {yields} K{pi} modes in order to constraint the CKM matrix. More significant constraints have been obtained with the SU(3) symmetry for B, Bs {yields} {pi}{pi}/ K{pi}/ KK modes. They are in good agreement with the Standard CKM fit. It has been shown that such an analysis will be competitive with the Standard CKM fit in the future and will allow to determine SU(3) breaking or New Physics parameters from data. (author)

    The COMPASS collaboration at CERN has investigated the $\\pi^-\\gamma \\to \\pi^-\\pi^-\\pi^+$ reaction at center-of-momentum energy below five pion masses, $\\sqrt{s} \\lt 5m_\\pi$ , embedded in the Primakoff reaction of 190 GeV pions impinging on a lead target. Exchange of quasi-real photons is selected by isolating the sharp Coulomb peak observed at smallest momentum transfers, $t' \\lt 0.001 GeV^2/c^2$. Using partial-wave analysis techniques, the scattering intensity of Coulomb production described in terms of chiral dynamics and its dependence on the 3pi-invariant mass $m_{3\\pi} = \\sqrt{s}$ were extracted. The absolute cross section was determined in seven bins of $\\sqrt{s}$ with an overall precision of 20%. At leading order, the result is found to be in good agreement with the prediction of chiral perturbation theory over the whole energy range investigated.

    Superficial temporal artery - middle cerebral artery (STA-MCA) bypass surgery might improve the cerebral blood flow (CBF) but fail to reduce the risk of post-surgical events such as ischaemic stroke. In this study, we studied retrospectively whether the risk of post-surgical events corresponded to the change in resting CBF and/or the change in vasoreactivity observed before and after STA-MCA surgery using N-isopropyl-I-123-p-iodoamphetamine ( 123 I-IMP) brain single-photon emission tomography (SPET). 123 I-IMP brain SPET images obtained at rest and following acetazolamide challenge both before and after STA-MCA surgery were studied in 30 patients. Resting CBF was estimated semiquantitatively using the resting count ratios of the middle cerebral artery (MCA) area to the cerebellum. Acetazolamide challenge was assumed to result in an average increase in flow of 40% in the cerebellum. The vasoreactive response was then estimated as the ratio of the change in counts (acetazolamide - rest) to the resting cerebellar counts multiplied by 1.4. We classified 14 patients (50.5±19.3 years) into group I, who had a change in their resting CBF from before to after surgery of >10%, and 16 patients (54.0±18.8 years) into group II, who had a change in their resting CBF from before to after surgery of ≤10%. Oxygen-15 positron emission tomography (PET) studies were performed in five patients from group I and five patients from group II. One post-surgical event occurred in group I while there were eight post-surgical events in group II (P<0.05). Resting CBF improved by 20.4%±7.5% in group I and by 0.9%±6.9% in group II patients after surgery (P<0.001). No significant difference in the improvement in vasoreactivity was observed between group I patients (32.6%±17.7%) and group II patients (24.6%±15.6%) following surgery. Patients in the group I PET subset showed normalization of oxygen extraction fraction (OEF) from 0.59±0.09 before surgery to 0.46±0.06 after surgery (P<0

    In a neutron spectrometry using proton recoil method, the neutronunfolding code is needed to unfold the measured proton spectrum to become theneutron spectrum. The process of the unfolding neutron in the existingneutron spectrometry which was successfully installed last year was doneseparately. This manuscript reports that the auto sequence code to integratethe neutron unfolding code UNFSPEC.EXE with the software facility of thePC-MCA Accuspec has been made and run successfully so that the new neutronspectrometry become compact. The auto sequence code was written based on therules in application program facility of PC-MCA Accuspec and then it wascompiled using AC-EXE. Result of the test of the auto sequence code showedthat for binning width 20, 30, and 40 giving a little different spectrumshape. The binning width around 30 gives a better spectrum in mean of givingsmall error compared to the others. (author)

    Quantum-correlated $\\psi(3770) \\to D\\bar{D}$ decays collected by the CLEO-c experiment are used to perform a first measurement of $F_+^{4\\pi}$, the fractional $CP$-even content of the self-conjugate decay $D \\to \\pi^+\\pi^-\\pi^+\\pi^-$, obtaining a value of $0.737 \\pm 0.028$. An important input to the measurement comes from the use of $D \\to K^0_{\\rm S}\\pi^+\\pi^-$ and $D \\to K^0_{\\rm L}\\pi^+\\pi^-$ decays to tag the signal mode. This same technique is applied to the channels $D \\to\\pi^+\\pi^-\\pi^0$ and $D \\to K^+K^-\\pi^0$, yielding $F_+^{\\pi\\pi\\pi^0} = 1.014 \\pm 0.045 \\pm 0.022$ and $F_+^{KK\\pi^0} = 0.734 \\pm 0.106 \\pm 0.054$, where the first uncertainty is statistical and the second systematic. These measurements are consistent with those of an earlier analysis, based on $CP$-eigenstate tags, and can be combined to give values of $F_+^{\\pi\\pi\\pi^0} = 0.973 \\pm 0.017$ and $F_+^{KK\\pi^0} = 0.732 \\pm 0.055$.

    Cardiac embolism accounts for a large proportion of ischemic stroke. Revascularization using systemic or intra-arterial thrombolysis is associated with increasing risks of cerebral hemorrhageas time passes from stroke onset. We report successful mechanicalthrombectomy from a distal branch of the middle cerebral artery (MCA)using a novel technique. A 72-year old man suffered an acute ischemic stroke from an echocardiographically proven ventricular thrombus due toa recent myocardial infarction. Intra-arterial administration of 4 mgrt-PA initiated at 5.7 hours post-ictus failed to recanalize an occluded superior division branch of the left MCA. At 6 hours,symptomatic embolic occlusion persisted. Mechanical extraction of the clot using an Attracter-18 device (Target Therapeutics, Freemont, CA) resulted in immediate recanalization of the MCA branch. Attracter-18 for acute occlusion of MCA branches may be considered in selected patients who fail conventional thrombolysis or are nearing closure of the therapeutic window for use of thrombolytic agents

    Twenty-seven patients with minor completed and major stroke in the chronic stage underwent superficial temporal artery-middle cerebral artery (STA-MCA) anastomosis. The regional cerebral blood flow (rCBF), using inhalation of stable xenon and computed tomographic scanning (Xe{sup s} CT-CBF study), and the mode of transit time (MTT) in the MCA territory using intra-arterial digital aortography were measured. Activated rCBF and MTT was measured 20 minutes after the administration of acetazolamide (10 mg/kg) in 14 patients. Nineteen of the 23 patients with minor stroke (Group 1) showed immediate improvement in their neurological state within a few days of the operation, while four patients with minor stroke (Group 2) and four patients with major stroke (Group 3) showed no improvement. Based on the rCBF obtained with the Xe{sup s} CT-CBF study, affected side rCBF/unaffected side rCBF and %f ((peak DSA number/affected side MTT)/(peak DSA number/unaffected side MTT)) were compared. There was a significant positive correlation. Affected side MTT in Group 1 was 6.41{plus minus}1.16 sec, preoperatively, and significantly decreased to 5.13{plus minus}0.91 sec after the operation. On the other hand, preoperative MTT in Group 2 was 4.40{plus minus}0.81 sec and 4.76{plus minus}0.89 sec, postoperatively. Preoperative %f in Group 1 was 0.514{plus minus}0.143 and significantly increased to 0.739{plus minus}0.154, postoperatively. Group 2 showed no change. Vasodilatory capacity with acetazolamide showed a marked improvement in Group 1, postoperativery. Our study indicated that if MTT is moderately lengthened, %f is moderately decreased, and vasodilatory capacity is impaired, in patients with minor ischemic stroke will benefit from STA-MCA anastomosis.

  9. AgPi: Agents on Raspberry Pi

    Full Text Available The Raspberry Pi and its variants have brought with them an aura of change in the world of embedded systems. With their impressive computation and communication capabilities and low footprint, these devices have thrown open the possibility of realizing a network of things in a very cost-effective manner. While such networks offer good solutions to prominent issues, they are indeed a long way from being smart or intelligent. Most of the currently available implementations of such a network of devices involve a centralized cloud-based server that contributes to making the necessary intelligent decisions, leaving these devices fairly underutilized. Though this paradigm provides for an easy and rapid solution, they have limited scalability, are less robust and at times prove to be expensive. In this paper, we introduce the concept of Agents on Raspberry Pi (AgPi as a cyber solution to enhance the smartness and flexibility of such embedded networks of physical devices in a decentralized manner. The use of a Multi-Agent System (MAS running on Raspberry Pis aids agents, both static and mobile, to govern the various activities within the network. Agents can act autonomously or on behalf of a human user and can collaborate, learn, adapt and act, thus contributing to embedded intelligence. This paper describes how Tartarus, a multi-agent platform, embedded on Raspberry Pis that constitute a network, can bring the best out of the system. To reveal the versatility of the concept of AgPi, an application for a Location-Aware and Tracking Service (LATS is presented. The results obtained from a comparison of data transfer cost between the conventional cloud-based approach with AgPi have also been included.

    The effect of STA-MCA bypass for ischemic cerebrovascular diseases (CVDs) on pure motor function using motor activation SPECT was evaluated and analyzed, and this effect with the resting cerebral blood flow and reserved capacity was compared. Motor activation SPECT were carried out on 22 cases with STA-MCA bypass for symptomatic ischemic CVDs. All motors activation SPECT using the finger opposition task on the affected side were performed before bypass, at 1 month, and 3 months after the bypass. Visual inspection was used to determine whether the result of the motor activation SPECT was as negative or positive. The activated region was detected anatomically precisely by superimposing the SPECT on the MRI. Before this study, the same examination was performed on normal controls. In controls, 91% showed the activated area on the sensorimotor cortex after the finger opposition tasks. Before bypass, the resting SPECT revealed reduction of cerebral blood flow (CBF) on the affected side in all cases. All cases also showed a disturbed response to acetazolamide (ACZ). Nine cases were positive in the motor activation SPECT. One month after bypass, the resting CBF increased in 11 cases. Seven showed preoperative positive motor activation. Fifteen cases were positive in the motor activation SPECT. Three months after bypass, 20 cases showed improvement in the resting CBF, and 19 cases were positive in the motor activation SPECT. Ten cases were negative in the preoperative motor activation SPECT. At one month after surgery, ACZ activation SPECT was performed in 12 cases. Five showed improvement of the response to ACZ. At 3 months after surgery, 8 of 12 cases treated with ACZ activation SPECT showed improved response to ACZ. In most of the cases, improved response to ACZ could be seen after response to motor activation improved. STA-MCA bypass is useful not only for resting CBF but also for pure motor function based on motor activation SPECT. (K.H.)

  14. Identification of a mouse Lactobacillus johnsonii strain with deconjugase activity against the FXR antagonist T-β-MCA.

    Directory of Open Access Journals (Sweden)

    Michael DiMarzio

    Full Text Available Bile salt hydrolase (BSH activity against the bile acid tauro-beta-muricholic acid (T-β-MCA was recently reported to mediate host bile acid, glucose, and lipid homeostasis via the farnesoid X receptor (FXR signaling pathway. An earlier study correlated decreased Lactobacillus abundance in the cecum with increased concentrations of intestinal T-β-MCA, an FXR antagonist. While several studies have characterized BSHs in lactobacilli, deconjugation of T-β-MCA remains poorly characterized among members of this genus, and therefore it was unclear what strain(s were responsible for this activity. Here, a strain of L. johnsonii with robust BSH activity against T-β-MCA in vitro was isolated from the cecum of a C57BL/6J mouse. A screening assay performed on a collection of 14 Lactobacillus strains from nine different species identified BSH substrate specificity for T-β-MCA only in two of three L. johnsonii strains. Genomic analysis of the two strains with this BSH activity revealed the presence of three bsh genes that are homologous to bsh genes in the previously sequenced human-associated strain L. johnsonii NCC533. Heterologous expression of several bsh genes in E. coli followed by enzymatic assays revealed broad differences in substrate specificity even among closely related bsh homologs, and suggests that the phylogeny of these enzymes does not closely correlate with substrate specificity. Predictive modeling allowed us to propose a potential mechanism driving differences in BSH activity for T-β-MCA in these homologs. Our data suggests that L. johnsonii regulates T-β-MCA levels in the mouse intestinal environment, and that this species may play a central role in FXR signaling in the mouse.

    The George Kuzmych Training Center (GKTC) was created at the Kyiv Institute for Nuclear Research as a result of collaborative efforts between the United States and Ukraine in 1998. Later the European Commission (EC) and Sweden joined the USA supporting MC&A aspects of the GKTC activity. The GKTC was designated by the Ukrainian Government to provide the MPC&A training and methodological assistance to nuclear facilities and nuclear specialists. In order to increase the efficiency of State MC&A system an essential number of new regulations, norms and rules was developed demanding regular and more intensive MC&A experts training from the Regulatory Body of Ukraine and all nuclear facilities. For this purpose ten training courses were developed by the GKTC under the EC contract taking into account both specifics of Ukrainian nuclear facilities and expertise level of their personnel. Along with the NDA training laboratory created with the US DOE financial support and methodological assistance in 2003, a new surveillance and containment laboratory was created under the EC contract and with US DOE financial support as well. Moreover, under the EC contract the laboratory was equipped with the state-of-the-art and most advanced means of surveillance and containment strengthening even more the GKTC training opportunities. As a result, the MC&A experts from all nuclear facilities and Regulatory Body of Ukraine can regularly be trained practically on all MC&A issues. This paper briefly describes the practical efforts applied to improve Ukrainian MC&A systems both at the State and facility levels and real results on the way to develop the National System for MC&A regular training at the GKTC, problems encountered and their solution, comments, suggestions and recommendations for the future activity to promote and improve the nuclear security culture in Ukraine.

  18. Zeros of the pi /sup +/ pi /sup -/ to pi /sup +/ pi /sup -/ amplitude (from data on pp to pi /sup -/ pi /sup +/)

    Recent data on the reaction pp to pi /sup -/ pi /sup +/ show four conspicuous dips in the angular distribution at fixed values of nu =t- u. The conjecture is made that the channel pi /sup -/ pi /sup +/ to pi /sup -/ pi /sup +/ has zeros at the same nu values. Using data of the CERN-Munich group, one can follow the zeros through the whole Mandelstam plane. The zeros pass through the intersections of s and t channel poles, as the Veneziano model predicts; however, away from these intersections, they propagate in a fashion systematically quite different from Veneziano's ansatz.

    We study the process e+e- -> pi+pi-pi+pi-gamma, with a photon emitted from the initial-state electron or positron, using 454.3 fb^-1 of data collected with the BABAR detector at SLAC, corresponding to approximately 260,000 signal events. We use these data to extract the non-radiative sigma(e+e- ->pi+pi-pi+pi-) cross section in the energy range from 0.6 to 4.5 Gev. The total uncertainty of the cross section measurement in the peak region is less than 3%, higher in precision than the corresponding results obtained from energy scan data.

  20. Investigating changes in brain network properties in HIV-associated neurocognitive disease (HAND) using mutual connectivity analysis (MCA)

    About 50% of subjects infected with HIV present deficits in cognitive domains, which are known collectively as HIV associated neurocognitive disorder (HAND). The underlying synaptodendritic damage can be captured using resting state functional MRI, as has been demonstrated by a few earlier studies. Such damage may induce topological changes of brain connectivity networks. We test this hypothesis by capturing the functional interdependence of 90 brain network nodes using a Mutual Connectivity Analysis (MCA) framework with non-linear time series modeling based on Generalized Radial Basis function (GRBF) neural networks. The network nodes are selected based on the regions defined in the Automated Anatomic Labeling (AAL) atlas. Each node is represented by the average time series of the voxels of that region. The resulting networks are then characterized using graph-theoretic measures that quantify various network topology properties at a global as well as at a local level. We tested for differences in these properties in network graphs obtained for 10 subjects (6 male and 4 female, 5 HIV+ and 5 HIV-). Global network properties captured some differences between these subject cohorts, though significant differences were seen only with the clustering coefficient measure. Local network properties, such as local efficiency and the degree of connections, captured significant differences in regions of the frontal lobe, precentral and cingulate cortex amongst a few others. These results suggest that our method can be used to effectively capture differences occurring in brain network connectivity properties revealed by resting-state functional MRI in neurological disease states, such as HAND.

    An analysis of $B^{\\pm}\\to DK^{\\pm}$ and $B^{\\pm}\\to D\\pi^{\\pm}$ decays is presented where the $D$ meson is reconstructed in the four-body final state $K^{\\pm}\\pi^{\\mp} \\pi^+ \\pi^-$. Using LHCb data corresponding to an integrated luminosity of $1.0{\\rm \\,fb}^{-1}$, first observations are made of the suppressed ADS modes $B^{\\pm}\\to [\\pi^{\\pm} K^{\\mp}\\pi^+\\pi^-]_D K^{\\pm}$ and $B^{\\pm}\\to [\\pi^{\\pm} K^{\\mp} \\pi^+\\pi^- ]_D\\pi^{\\pm}$ with a significance of $5.1\\sigma$ and greater than $10\\sigma$, respectively. Measurements of $CP$ asymmetries and $CP$-conserving ratios of partial widths from this family of decays are also performed. The magnitude of the ratio between the suppressed and favoured $B^{\\pm}\\to DK^{\\pm}$ amplitudes is determined to be $r^K_B = 0.097 \\pm{0.011}$.

    A study of resonance formation is presented in the $\\pi^+\\pi^-\\pi^0$ final state in two-photon collisions at LEP. The $a_2(1320)$ radiative width is measured to be $\\Gamma_{\\gamma\\gamma}=0.98\\pm0.05\\pm0.09$ keV{}. The helicity 2 production is dominant. Exclusive $\\pi^+\\pi^-\\pi^0$ production has also been studied in the mass region above the $a_2$ in the $\\rho\\pi$ and $f_2\\pi$ channels. This region is dominated by a $\\rm J^P$=$2^+$ helicity 2 wave.

    Using 355 pb;{-1} of data collected by the CDF II detector in pp[over ] collisions at sqrt[s]=1.96 TeV at the Fermilab Tevatron, we study the fully reconstructed hadronic decays B_{(s)};{0}-->D_{(s)};{-}pi;{+} and B_{(s)};{0}-->D_{(s)};{-}pi;{+}pi;{+}pi;{-}. We present the first measurement of the ratio of branching fractions B(B_{s};{0}-->D_{s};{-}pi;{+}pi;{+}pi;{-})/B(B;{0}-->D;{-}pi;{+}pi;{+}pi;{-})=1.05+/-0.10(stat)+/-0.22(syst). We also update our measurement of B(B_{s};{0}-->D_{s};{-}pi;{+})/B(B;{0}-->D;{-}pi;{+}) to 1.13+/-0.08(stat)+/-0.23(syst), improving the statistical uncertainty by more than a factor of 2. We find B(B_{s};{0}-->D_{s};{-}pi;{+})=[3.8+/-0.3(stat)+/-1.3(syst)]x10;{-3} and B(B_{s};{0}-->D_{s};{-}pi;{+}pi;{+}pi;{-})=[8.4+/-0.8(stat)+/-3.2(syst)]x10;{-3}.

    A search for $CP$ violation in the phase-space structures of $D^{0}$ and $\\bar{D^{0}}$ decays to the final states $K^{-}K^{+}\\pi^{-}\\pi^{+}$ and $\\pi^{-}\\pi^{+}\\pi^{+}\\pi^{-}$ is presented. The search is carried out with a data set corresponding to an integrated luminosity of 1.0 fb$^{−1}$ collected in 2011 by the LHCb experiment in $pp$ collisions at a centre-of-mass energy of 7 TeV. For the $K^{-}K^{+}\\pi^{-}\\pi^{+}$ final state, the four-body phase space is divided into 32 bins, each bin with approximately 1800 decays. The $p$-value under the hypothesis of no $CP$ violation is 9.1 %, and in no bin is a $CP$ asymmetry greater than 6.5 % observed. The phase space of the $\\pi^{-}\\pi^{+}\\pi^{+}\\pi^{-}$ final state is partitioned into 128 bins, each bin with approximately 2500 decays. The p-value under the hypothesis of no $CP$ violation is 41 %, and in no bin is a $CP$ asymmetry greater than 5.5 % observed. All results are consistent with the hypothesis of no $CP$ violation at the current sensitivity.

    A measurement of the direct CP violating charge asymmetries of the Dalitz plot linear slopes $A_g=(g^+-g^-)/(g^++g^-)$ in $K^\\pm\\to\\pi^\\pm\\pi^+\\pi^-$ and $K^\\pm\\to\\pi^\\pm\\pi^0\\pi^0$ decays by the NA48/2 experiment at CERN SPS is presented. A new technique of asymmetry measurement involving simultaneous $K^+$ and $K^-$ beams and a large data sample collected allowed a result of an unprecedented precision. The charge asymmetries were measured to be $A^c_g=(-1.5\\pm2.1)\\times10^{-4}$ with $3.11\\times 10^9$ $K^{\\pm}\\to\\pi^\\pm\\pi^+\\pi^-$ decays, and $A^n_g=(1.8\\pm1.8)\\times10^{-4}$ with $9.13\\times 10^7$ $K^{\\pm}\\to\\pi^\\pm\\pi^0\\pi^0$ decays. The precision of the results is limited mainly by the size of the data sample.

    Under the U.S.-Russian Material Protection, Control and Accounting (MPC&A) Program, the Material Control and Accounting Measurements (MCAM) Project has supported a joint U.S.-Russian effort to coordinate improvements of the Russian MC&A measurement system. These efforts have resulted in the development of a MC&A Equipment and Methodological Support (MEMS) Strategic Plan (SP), developed by the Russian MEM Working Group. The MEMS SP covers implementation of MC&A measurement equipment, as well as the development, attestation and implementation of measurement methodologies and reference materials at the facility and industry levels. This paper provides an overview of the activities conducted under the MEMS SP, as well as a status on current efforts to develop reference materials, implement destructive and nondestructive assay measurement methodologies, and implement sample exchange, scrap and holdup measurement programs across Russian nuclear facilities.

    The observation of hydrogen-like $\\pi K$ atoms, consisting of $\\pi^- K^+$ or $\\pi^+ K^-$ mesons, is presented. The atoms have been produced by 24 GeV/$c$ protons from the CERN PS accelerator, interacting with platinum or nickel foil targets. The breakup (ionisation) of $\\pi K$ atoms in the same targets yields characteristic $\\pi K$ pairs, called ``atomic pairs'', with small relative momenta in the pair centre-of-mass system. The upgraded DIRAC experiment has observed $349\\pm62$ such atomic $\\pi K$ pairs, corresponding to a signal of 5.6 standard deviations.

    The results of a search for a possible evidence of a pi /sup +/ pi /sup +/ resonant state in the np to pi /sup +/ pi /sup +/ pi /sup -/ annihilation reaction with data collected by the OBELIX Experiment are presented. The study has been performed by means of a partial wave analysis in the frame of the isobar model. Production fractions for a possible pi /sup +/ pi /sup +/ resonance have been evaluated. The observed effects at the pi /sup +/ pi /sup +/ threshold may be described reasonably well by the contributions of f/sub 2/(1270), f /sub 0/(1500), f/sub 2/(1565) and rho (1450) states and their interferences, but a meaningful statistical indication for a pi /sup +/ pi /sup +/ scalar state at about 1400 MeV emerges from the analysis.

  19. Feasibility study of the {eta}'{yields} {pi}{sup +} {pi}{sup -} {pi}{sup 0} decay using WASA-at-COSY apparatus

    Energy Technology Data Exchange (ETDEWEB)

    Zielinski, M.

    2008-07-15

    One of the objectives of the vast physics programme of the recently commissioned WASA-at-COSY facility is the study of fundamental symmetries via the measurements of the {eta} and {eta}' mesons decays. Especially interesting are isospin violating hadronic precesses of these mesons into 3{pi} systems driven by the term of QCD Lagrangian which depends on the mass difference of the u and d quarks. When an {eta} or an {eta}' meson is created in the hadronic reaction signals from such decays may be significantly obscured by the prompt production of {pi} mesons. In this thesis we present the estimation of the upper limit of the background due to prompt pion production for the {eta}'{yields}3{pi}{sup 0} and {eta}'{yields}{pi}{sup +}{pi}{sup -}{pi}{sup 0} decays. Using the data from proton-proton collisions measured by the COSY-11 group we have extracted differential cross sections for the multimeson production with the invariant mass corresponding to the mass of the {eta}' meson. Based on these results and on parametrizations of the total cross sections for the {eta}' meson as well as parametrization of the upper limit for the prompt pi{sup +}pi{sup -}pi{sup 0} production in the collisions of protons we discuss in details the feasibility of a measurement of the {eta}' meson decay into 3{pi} channels with the WASA-at-COSY facility. Based on the chiral unitary approach the value of the branching ratio BR({eta}'{yields}{pi}{sup +}{pi}{sup -}{pi}{sup 0}) was recently predicted to be about 1%. We show that the WASA-at-COSY has a potential to verify this result empirically. (orig.)

  20. Plasmodium falciparum metacaspase PfMCA-1 triggers a z-VAD-fmk inhibitable protease to promote cell death.

    Directory of Open Access Journals (Sweden)

    Benoît Meslin

    Full Text Available Activation of proteolytic cell death pathways may circumvent drug resistance in deadly protozoan parasites such as Plasmodium falciparum and Leishmania. To this end, it is important to define the cell death pathway(s in parasites and thus characterize proteases such as metacaspases (MCA, which have been reported to induce cell death in plants and Leishmania parasites. We, therefore, investigated whether the cell death function of MCA is conserved in different protozoan parasite species such as Plasmodium falciparum and Leishmania major, focusing on the substrate specificity and functional role in cell survival as compared to Saccharomyces cerevisae. Our results show that, similarly to Leishmania, Plasmodium MCA exhibits a calcium-dependent, arginine-specific protease activity and its expression in yeast induced growth inhibition as well as an 82% increase in cell death under oxidative stress, a situation encountered by parasites during the host or when exposed to drugs such as artemisins. Furthermore, we show that MCA cell death pathways in both Plasmodium and Leishmania, involve a z-VAD-fmk inhibitable protease. Our data provide evidence that MCA from both Leishmania and Plasmodium falciparum is able to induce cell death in stress conditions, where it specifically activates a downstream enzyme as part of a cell death pathway. This enzymatic activity is also induced by the antimalarial drug chloroquine in erythrocytic stages of Plasmodium falciparum. Interestingly, we found that blocking parasite cell death influences their drug sensitivity, a result which could be used to create therapeutic strategies that by-pass drug resistance mechanisms by acting directly on the innate pathways of protozoan cell death.

    We report the results from a study of the full sample of $~6.031 x 10^{7} K^{\\pm} \\to \\pi^{\\pm} \\pi^{0} \\pi^{0}$ decays recorded by the NA48/2 experiment at the CERN SPS. As first observed in this experiment, the $\\pi^{0} \\pi^{0}$ invariant mass (M_00) distribution shows a cusp-like anomaly in the region around $M_{00} = 2m_{+}$, where m_{+} is the charged pion mass. This anomaly has been interpreted as an effect due mainly to the final state charge exchange scattering process $\\pi^{+}\\pi^{-} \\to \\pi^{0} \\pi^{0}$ in $K^{\\pm} \\to \\pi^{\\pm} \\pi^{+} \\pi^{-}$ decay. Fits to the M_{00} distribution using two different theoretical models provide the presently most precise determination of $a_{0}-a_{2}$, the difference between the pi pi S-wave scattering lengths in the isospin I = 0 and I = 2 states. Higher-order pi pi rescattering terms, included in the two models, allow also an independent, though less precise, determination of a_2.

    The pi pi phase-shifts have been determined by a Chew-Low extrapolation in the pi pi mass region from 500 to 1500 MeV using data of a spark chamber experiment on pi /sup -/p to pi /sup -/ pi /sup +/n at 17.2 GeV/c, which yielded 318000 events. The authors find an I=0 s- wave phase shift which increases slowly, passing through 90 degrees near 900 MeV, and then rises very rapidly. The old 'up' solution is eliminated on the basis of fits in the mass region from 900-1000 MeV. (13 refs).

    This thesis describes a Dalitz plot analysis of B{sup 0} {yields} K{sup +}{pi}{sup -}{pi}{sup 0} decays. The data sample comprises 213 million {Upsilon}(4S) {yields} B{bar B} decays collected with the BABAR detector at the PEP-II asymmetric-energy B Factory at the Stanford Linear Accelerator Center in California (SLAC). Preliminary results are presented for measurements of the inclusive branching fraction, quasi-two-body fractions and CP-violating charge asymmetries for intermediate states including K*(892){sup +}{pi}{sup -} and {rho}(770){sup -}K{sup +}. Observations of B{sup 0} decays to the K{pi} S-wave intermediate states, K*{sub 0}(1430){sup +}{pi}{sup -} and K*{sub 0}(1430){sup 0}{pi}{sup 0}, are reported. Evidence of the decay B{sup 0} {yields} K*(892){sup 0}{pi}{sup 0} is seen. We set upper limits at 90% confidence level on branching fractions of the nonresonant and other less significant intermediate states.

  5. Raspberry Pi Eclipse Experiments

    The 21 August 2017 solar eclipse was an excellent opportunity for electronics and science enthusiasts to collect data during a fascinating phenomenon. With my recent personal interest in Raspberry Pis, I thought measuring how much the temperature and illuminance changes during a total solar eclipse would be fun and informational.Previous observations of total solar eclipses have remarked on the temperature drop during totality. Illuminance (ambient light) varies over 7 orders of magnitude from day to night and is highly dependent on relative positions of Sun, Earth, and Moon. I wondered whether totality was really as dark as night.Using a Raspberry Pi Zero W, a Pimoroni Enviro pHAT, and a portable USB charger, I collected environmental temperature; CPU temperature (because the environmental temperature sensor sat very near the CPU on the Raspberry Pi); barometric pressure; ambient light; R, G, and B colors; and x, y, and z acceleration (for marking times when I moved the sensor) data at a ~15 second cadence starting at about 5 am until 1:30 pm from my eclipse observation site in Glendo, WY. Totality occurred from 11:45 to 11:47 am, lasting about 2 minutes and 30 seconds.The Raspberry Pi recorded a >20 degree F drop in temperature during the eclipse, and the illuminance during totality was equivalent to twilight measurements earlier in the day. A limitation in the ambient light sensor prevented accurate measurements of broad daylight and most of the partial phase of the eclipse, but an alternate ambient light sensor combined with the Raspberry Pi setup would make this a cost-efficient set-up for illuminance studies.I will present data from the ambient light sensor, temperature sensor, and color sensor, noting caveats from my experiments, lessons learned for next time, and suggestions for anyone who wants to perform similar experiments for themselves or with a classroom.

    In many countries, the protease inhibitor (SERPINA1) PI*S allele is more common than PI*Z, the allele responsible for most cases of chronic obstructive pulmonary disease (COPD) due to severe alpha 1-antitrypsin deficiency. However, the risk of COPD due to the PI*S allele is not clear. The current...... authors located studies that addressed the risk of COPD or measured lung function in individuals with the PI SZ, PI MS and PI SS genotypes. A separate meta-analysis for each genotype was performed. Aggregating data from six studies, the odds ratio (OR) for COPD in PI SZ compound heterozygotes compared...... with PI MM (normal) individuals was significantly increased at 3.26 (95% confidence intervals (CI): 1.24-8.57). In 17 cross-sectional and case-control studies, the OR for COPD in PI MS heterozygotes was 1.19 (95%CI: 1.02-1.38). However, PI MS genotype was not associated with COPD risk after correcting...

  7. Adaptation to Climate Change in Forestry: A Multiple Correspondence Analysis (MCA

    Directory of Open Access Journals (Sweden)

    Marielle Brunette

    2018-01-01

    Full Text Available We analyze economic perspectives of forest adaptation to risk attributes, caused mostly by climate change. We construct a database with 89 systematically chosen articles, dealing simultaneously with climate, adaptation, risk and economy. We classify the database with regard to 18 variables bearing on the characteristics of the paper, the description of the risk and the adaptation strategy, the topic and the corresponding results. To achieve a “high level-of-evidence”, we realize a multiple correspondence analysis (MCA to identify which variables were found in combination with one other in the literature and make distinct groupings affecting adaptive decisions. We identify three groups: (i profit and production; (ii microeconomic risk-handling; and (iii decision and behavior. The first group includes economic costs and benefits as the driver of adaptation and prioritizes simulation, and a mix of theoretical and empirical economic approach. The second group distinctly involves risk-related issues, in particular its management by adaptation. The third group gathers a large set of social and behavioral variables affecting management decisions collected through questionnaires. Such an approach allows the identification of gaps in the literature, concerning the impact of owners’ preferences towards risk and uncertainty regarding adaptation decisions, the fact that adaptation was often reduced in an attempt to adapt to the increasing risk of wildfire, or the existence of a regional bias.

    The outcome of patients who show no early response to intravenous (i.v.) tissue plasminogen activator (tPA) therapy is poor. The objective of this study was to evaluate the feasibility of rescue localized intra-arterial thrombolysis (LIT) therapy for acute ischemic stroke patients after an early non-responsive i.v. tPA therapy. Patients with proximal MCA occlusions who were treated by LIT (n=10) after failure of early response [no improvement or improvement of National Institute of Health Stroke Scale (NIHSS) scores of ≤3] to i.v. tPA therapy (0.9 mg/kg - 10% bolus and 90% i.v. infusion over 60 min) were selected. The recanalization rates, incidence of post-thrombolysis hemorrhage and clinical outcomes [baseline and discharge NIHSS scores, mortality, 3 months Barthel index (BI) and modified Rankin score (mRS)] were evaluated. Rescue LIT therapy was performed on ten MCA occlusion patients (male:female=3:7, mean age 71 years). The mean time between the initiation of i.v. tPA therapy and the initiation of intra-arterial urokinase (i.a. UK) was 117±25.0 min [time to i.v. tPA 137±32 min; time to digital subtraction angiography (DSA) 221±42 min; time to i.a. UK 260±46 min]. The baseline NIHSS scores showed significant improvement at discharge (median from 18 to 6). Symptomatic hemorrhage and, consequent, mortality were noted in 2/10 (20%) patients. Three months good outcome was noted in 4/10 (40%, mRS 0-2) and 3/10 (30%, BI ≥95). In conclusion, rescue LIT therapy can be considered as a treatment option for patients not showing early response to full dose i.v. tPA therapy. Larger scale studies for further validation of this protocol may be necessary. (orig.)

    We present an observation of the decay B sup 0 -> pi sup 0 pi sup 0 based on a sample of 124 million B(bar B) pairs recorded by the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC. We observe 46 +- 13 +- 3 events, where the first error is statistical and the second is systematic, corresponding to a significance of 4.2 standard deviations including systematic uncertainties. We measure the branching fraction BETA(B sup 0 -> pi sup 0 pi sup 0) = (2.1 +- 0.6 +- 0.3) x 10 sup - sup 6 , averaged over B sup 0 and (bar B) sup 0 decays.

    Abstract . The Three Gorges dam of China is one of the largest and expensive hydropower projects of the world. The four main purposes of the project are flood control,energy production, improved navigation and fresh water supply. The dam project has been completed and running successfully with the potential benefits. However, this project is still a controversial issue among many environmentalists and socialists due to various impacts. This study focuses on the benefit and the impacts of the project, and also evaluates the performance of the project using multi-criteria analysis (MCA) approach from a sustainable perspective. Different sustainability criteria related with the dam project have been identified and used for the ranking and rating process. The final result of MCA comes with this scoring process and pairwise comparison, which evaluates the performance of the project considering different positive and negative aspects.

    The COMPASS experiment at the CERN SPS has studied the diffractive dissociation of negative pions into the pi- pi- pi+ final state using a 190 GeV/c pion beam hitting a lead target. A partial wave analysis has been performed on a sample of 420000 events taken at values of the squared 4-momentum transfer t' between 0.1 and 1 GeV^2/c^2. The well-known resonances a1(1260), a2(1320), and pi2(1670) are clearly observed. In addition, the data show a significant natural parity exchange production of a resonance with spin-exotic quantum numbers J^PC = 1-+ at 1.66 GeV/c^2 decaying to rho pi. The resonant nature of this wave is evident from the mass-dependent phase differences to the J^PC = 2-+ and 1++ waves. From a mass-dependent fit a resonance mass of 1660 +- 10+0-64 MeV/c^2 and a width of 269+-21+42-64 MeV/c^2 is deduced.

  16. The use of multi-criteria analysis (MCA) for evaluating feasible countermeasures after an accidental release of radioactivity

    The aim of this study is to establish a system that enables rational decisions to be taken for reducing (if necessary) the radiological risk to a population. These decisions normally concern whether a particular food product will be consumed or not, as well as wether it should be diverted for other uses. To evaluate the consequences of such actions, many different criteria have to be taken into account such as the radiological risk, nutritional and environmental criteria, current technical intervention levels, economic costs and public reaction. Under the guidance of the Institute of Automation and Operations Research at the University of Fribourg a Multi-Criteria-Analysis (MCA) approach, based on the most recent developments in decision theory, is being elaborated. MCA requires input from a suite of sub-models combined with basic input data. For the radiological impact model the German code ECOSYS will be adapted for Swiss conditions. Furthermore, input data on the effect of food processing on radionuclide content of foodstuffs and consumption habits are needed. MCA thus allows the consequences of different countermeasures to be assessed in relation to the different governing criteria. In order to allow efficient use of this technique it shall be implemented as a user friendly computerized decision support system. In this paper, an example of different countermeasures to reduce the dose from milk contaminated with I-131 resulting from a reactor accident is given

  17. Pi-pi Stacking Mediated Cooperative Mechanism for Human Cytochrome P450 3A4

    2015-04-01

    Full Text Available Human Cytochrome P450 3A4 (CYP3A4 is an important member of the cytochrome P450 superfamily with responsibility for metabolizing ~50% of clinical drugs. Experimental evidence showed that CYP3A4 can adopt multiple substrates in its active site to form a cooperative binding model, accelerating substrate metabolism efficiency. In the current study, we constructed both normal and cooperative binding models of human CYP3A4 with antifungal drug ketoconazoles (KLN. Molecular dynamics simulation and free energy calculation were then carried out to study the cooperative binding mechanism. Our simulation showed that the second KLN in the cooperative binding model had a positive impact on the first one binding in the active site by two significant pi-pi stacking interactions. The first one was formed by Phe215, functioning to position the first KLN in a favorable orientation in the active site for further metabolism reactions. The second one was contributed by Phe304. This pi-pi stacking was enhanced in the cooperative binding model by the parallel conformation between the aromatic rings in Phe304 and the dioxolan moiety of the first KLN. These findings can provide an atomic insight into the cooperative binding in CYP3A4, revealing a novel pi-pi stacking mechanism for drug-drug interactions.

    Interpretation of CP violation measurements using charmonium decays, in both the B0 and Bs systems, can be subject to changes due to "penguin" type diagrams. These effects can be investigated using measurements of the Cabibbo-suppressed B0->J/\\psi pi+pi- decays. The final state composition of this channel is investigated using a 1.0/fb sample of data produced in 7 TeV pp collisions at the LHC and collected by the LHCb experiment. A modified Dalitz plot analysis is performed using both the invariant mass spectra and the decay angular distributions. An improved measurement of the B0->J/\\psi pi+pi- branching fraction of (3.97 +/-0.09+/- 0.11 +/- 0.16)x10^{-5} is reported where the first uncertainty is statistical, the second is systematic and the third is due to the uncertainty of the branching fraction of the decay B- -> J/\\psi K- used as a normalization channel. In the J/\\psi pi+pi- final state significant production of f0(500) and rho(770) resonances is found, both of which can be used for CP violation studie...

    Temperature dependence of the lifetime {tau}3 and intensity I{sub 3} of the long-lived ortho-positronium (o-Ps) component was measured for two polyimides PI189 and PI304 both below and above glass-transition temperatures Tg of these polymers. First heating runs of the experiments revealed anomalous, irregular behavior of the lifetime {tau}3 in both PI in the vicinity (below) of the glass transition temperature. The effect was similar to that discussed recently for a number of PI. However, on the cooling stage of the first cycle and on the heating run of the second cycle, such irregularities disappeared. These results show that anomalous behavior of annihilation characteristics of o-Ps in our PI samples were due not to anomalous behavior of PI structure itself close to Tg point (not to a specific phase transition), but to removal of residual solvent in vicinity of Tg during the first heating cycle. Different approaches to estimations of the specific hole volume and of the holes number density N on the basis of positron annihilation data are discussed. Final estimation for PI189 gives the fractional free volume h=3.35% and N=0.44x1027m-3. The effects of positron trapping by polar-CO groups on annihilation characteristics of PI and on the obtained value of N are also considered.

    Full Text Available In this article we introduce a new concept called Alpha-skew Pi-Armendariz rings (Alpha - S Pi - ARas a generalization of the notion of Alpha-skew Armendariz rings.Another important goal behind studying this class of rings is to employ it in order to design a modern algorithm of an identification scheme according to the evolution of using modern algebra in the applications of the field of cryptography.We investigate general properties of this concept and give examples for illustration. Furthermore, this paperstudy the relationship between this concept and some previous notions related to Alpha-skew Armendariz rings. It clearly presents that every weak Alpha-skew Armendariz ring is Alpha-skew Pi-Armendariz (Alpha-S Pi-AR. Also, thisarticle showsthat the concepts of Alpha-skew Armendariz rings and Alpha-skew Pi- Armendariz rings are equivalent in case R is 2-primal and semiprime ring.Moreover, this paper proves for a semicommutative Alpha-compatible ringR that if R[x;Alpha] is nil-Armendariz, thenR is an Alpha-S Pi-AR. In addition, if R is an Alpha - S Pi -AR, 2-primal and semiprime ring, then N(R[x;Alpha]=N(R[x;Alpha]. Finally, we look forwardthat Alpha-skew Pi-Armendariz rings (Alpha-S Pi-ARbe more effect (due to their properties in the field of cryptography than Pi-Armendariz rings, weak Armendariz rings and others.For these properties and characterizations of the introduced concept Alpha-S Pi-AR, we aspire to design a novel algorithm of an identification scheme.

    The time-dependence of the decay rate of initially pure K/sup 0/ into the final state ( pi /sup +/ pi /sup -/ pi /sup 0/) has been studied in search for the decay K/sup 0//sub S/ to pi /sup +/ pi /sup -/ pi /sup 0/. No evidence is found in a sample of 384 observed events. The ratio of the CP-violating K/sup 0//sub S/ amplitude and the K/sup 0 //sub L/ amplitude is eta /sub +-0/=(0.13(+0.17-0.20))+i(0.17 (+0.27-0.26)); the ratio of the CP-conserving K/sup 0//sub S/ amplitude and K/sup 0//sub L/ amplitude is mod rho mod <0.4. The energy dependence of the K/sup 0/ to pi /sup +/ pi /sup -/ pi /sup 0/ matrix element is found to be a/sub +-0/=-0.31+or-0.03. (12 refs).

  7. Cryogenic silicon detectors and analysis of Primakoff contributions to the reaction {pi}{sup -}Pb {yields} {pi}{sup -}{pi}{sup -}{pi}{sup +}Pb at COMPASS

    An important part of the physics programme of the COMPASS experiment at CERN is the measurement of reactions with hadron beam particles impinging on fixed targets at small momentum transfer. These measurements require tracking of charged particles with high precision, which is only reachable employing silicon microstrip detectors placed around the target, both as a part of the beam telescope and in the first part of the spectrometer. These detectors have been operated at a sensor temperature of 200 K starting with the 2009 beam time. They are cooled with liquid nitrogen in thin capillaries attached to the silicon sensors. For stable long-term operation, various extensions around the previously existing setup were required. Particularly the mechanical stability of the cooled detector modules concerning thermal deformation, as well as the cooling stability, have been improved to the level where installation in the experiment became feasible. The detector performance profits significantly from the cryogenic operation, so that a time resolution in the range of 1.4-1.8 ns and a spatial resolution of 4-6 {mu}m and 7-11 {mu}m (for two and one strips hit, respectively) is reached. This corresponds to an improvement of 15-20% with respect to the warm operation. Meson spectroscopy using a high-energetic pion beam impinging on heavy nuclear targets features both diffractive and Primakoff, i.e. electro-magnetic, production of the final state, the latter becoming competitive particularly at lowest momentum transfer t'. Four million exclusive {pi}{sup -}{pi}{sup -}{pi}{sup +} final state events, emerging from {pi}{sup -} beam scattering off a lead target, have been recorded during the COMPASS 2004 hadron run. About one million feature t' < 10{sup -3} GeV{sup 2}/c{sup 2}. Employing partial-wave analysis techniques, Primakoff-produced resonances, and the interference between Primakoff and diffractive production have been observed. Using the free decay of the kaon

    The Dalitz plot analysis technique is used to study the resonant substructures of $B^- \\to D^+ \\pi^- \\pi^-$ decays in a data sample corresponding to 3.0 fb$^-1$ of $pp$ collision data recorded by the LHCb experiment during 2011 and 2012. A model-independent analysis of the angular moments demonstrates the presence of resonances with spins 1, 2 and 3 at high $D^+\\pi^-$ mass. The data are fitted with an amplitude model composed of a quasi-model-independent function to describe the $D^+\\pi^-$ S-wave together with virtual contributions from the $D^*(2007)^{0}$ and $B^{*0}$ states, and components corresponding to the $D^*_2(2460)^{0}$, $D^*_1(2680)^{0}$, $D^*_3(2760)^{0}$ and $D^*_2(3000)^{0}$ resonances. The masses and widths of these resonances are determined together with the branching fractions for their production in $B^- \\to D^+ \\pi^- \\pi^-$ decays. The $D^+\\pi^-$ S-wave has phase motion consistent with that expected due to the presence of the $D^*_0(2400)^{0}$ state. These results constitute the first obser...

    A partial-wave analysis of the (3 pi )/sup 0/ system produced peripherally in the reaction K/sup -/p to pi /sup +/ pi /sup -/ pi /sup 0/ Lambda at 4.2 GeV/c is presented. The observation of the weak Lambda decay allows a determination of all the transverse production amplitudes except for two phases. The production of known resonances having decay modes other than 3 pi is used to test the isobar model ansatz. Significant omega (783), phi (1020) and A/sub 2/(1310) production is observed. The spin parity of the omega *(1675) is established as 3/sup -/. No evidence for production of other resonances, such as axial vector-mesons, is found. (23 refs).

    We present a measurement of relative partial widths and decay rate CP asymmetries in K-K+ and pi(-)pi(+) decays of D0 mesons produced in pp collisions at sqrt[s]=1.96 TeV. We use a sample of 2x10(5) D(*+)-->D0pi(+) (and charge conjugate) decays with the D0 decaying to K-pi(+), K-K+, and pi(-)pi(+), corresponding to 123 pb(-1) of data collected by the Collider Detector at Fermilab II experiment at the Fermilab Tevatron collider. No significant direct CP violation is observed. We measure Gamma(D0-->K-K+)/Gamma(D0-->K-pi(+))=0.0992+/-0.0011+/-0.0012, Gamma(D0-->pi(-)pi(+))/Gamma(D0-->K-pi(+))=0.035 94+/-0.000 54+/-0.000 40, A(CP)(K-K+)=(2.0+/-1.2+/-0.6)%, and A(CP)(pi(-)pi(+))=(1.0+/-1.3+/-0.6)%, where, in all cases, the first uncertainty is statistical and the second is systematic.

    Proton-proton collision data recorded in 2011 and 2012 by the LHCb experiment, corresponding to an integrated luminosity of 3.0 fb$^{-1}$i, are analysed to search for the charmless ${B^0 \\to \\rho^0 \\rho^0}$ decay. More than 600 ${B^0 \\to (\\pi^+\\pi^-)(\\pi^+\\pi^-)}$ signal decays are selected and used to perform an amplitude analysis from which the ${B^0 \\to \\rho^0 \\rho^0}$ decay is observed for the first time with 7.1 standard deviations significance. The fraction of ${B^0 \\to \\rho^0 \\rho^0}$ decays yielding a longitudinally polarised final state is measured to be $fL = 0.745^{+0.048}_{-0.058} ({\\rm stat}) \\pm 0.034 ({\\rm syst})$. The ${B^0 \\to \\rho^0 \\rho^0}$ branching fraction, using the ${B^0 \\to \\phi K^*(892)^{0}}$ decay as reference, is also reported as $\\mathcal B (B^0 \\to \\rho^0 \\rho^0) = (0.94 \\pm 0.17 ({\\rm stat}) \\pm 0.09 ({\\rm syst}) \\pm 0.06 ({\\rm BF})) \\times 10^{-6}$.

  13. Direct CP violation in B -> pi sup +pi sup -pi. Determination of alpha without discrete ambiguity

    Direct CP violation in the hadronic decays B-bar sup 0 -> pi sup +pi sup -pi sup 0 is investigated near the peak of the rho sup 0 taking into account the effect of rho - omega mixing. Branching ratio for processes B sup+- sup , sup 0 -> rho sup+- sup , sup 0 pi sup+- sup , sup 0 and B sup - -> omega pi sup - are calculated as well. We find that the CP violation asymmetry is strongly dependent on the CKM matrix elements. For a fixed N sub c sup e sup f sup f , the CP violation asymmetry, a, has a maximum of order - 40% to - 70% for B-bar sup 0 -> rho sup 0 (omega)pi sup 0 when the invariant mass of the pi sup +pi sup - pair is in the vicinity of the omega resonance. The sensitivity of the asymmetry to N sub c sup e sup f sup f is small in that case. Moreover, we find that in the range of N sub c sup e sup f sup f which is allowed by the most recent experimental branching ratios from the BABAR, BELLE and CLEO Collaborations, the sign of sin delta is always positive. Thus, a measurement of direct CP violation in...

    Activation-induced increase in cerebral blood flow is coupled to enhanced metabolic activity, maybe with brain tissue redox state and oxygen tension as key modulators. To evaluate this hypothesis at the onset of exercise in humans, blood was sampled at 0.1 to 0.2 Hz from the radial artery and right...... internal jugular vein, while middle cerebral artery mean flow velocity (MCA V(mean)) was recorded. Both the arterial and venous lactate-to-pyruvate ratio increased after 10 s (P capillary...... state and oxygenation as potential modulators of an increase in cerebral blood flow at the onset of exercise....

    The data on the pi- p --> M0 n, with M0 = pi0 pi0 pi0 or pi0 pi0 eta obtained in the GAMS experiment may be useful to study the sigma(400--700) and a_1^chi (1000), which can be taken as chiral partners of pi and rho, respectively. A preliminary analysis for 3pi0 invariant mass spectra gives a support for the assumed a_1^chi with a mass of 930 MeV and Gamma = 170 MeV.

    The decays $B^+\\rightarrow J/\\psi 3\\pi^+ 2\\pi^-$ and $B^+\\rightarrow \\psi(2S) \\pi^+\\pi^+\\pi^-$ are observed for the first time using a data sample corresponding to an integrated luminosity of $3.0fb^{-1}$, collected by the LHCb experiment in proton-proton collisions at the centre-of-mass energies of 7 and 8 TeV. The branching fractions relative to that of $B^+ \\rightarrow \\psi(2S)K^+$ are measured to be \\begin{eqnarray*} \\frac {\\mathcal{B}\\left( B^+\\rightarrow J/\\psi 3\\pi^+ 2\\pi^- \\right)} {\\mathcal{B}\\left( B^+ \\rightarrow \\psi(2S)K^+ \\right)} & = & \\left( 1.88\\pm0.17\\pm0.09\\right)\\times10^{-2}, \\\\ \\frac {\\mathcal{B}\\left( B^+\\rightarrow \\psi(2S) \\pi^+\\pi^+\\pi^- \\right)} {\\mathcal{B}\\left( B^+ \\rightarrow \\psi(2S)K^+ \\right) } & = & \\left( 3.04\\pm0.50\\pm0.26\\right)\\times10^{-2}, \\end{eqnarray*} where the first uncertainties are statistical and the second are systematic.

  18. PI-PI scattering at high complex energies

    International Nuclear Information System (INIS)

    Ciulli, S.; Verzegnassi, C.

    1976-12-01

    We estrapolate the PI-PI amplitudes with isospin one and two in the t-channel onto the imaginary ν approximately equal to (s - u)/4msub(π) axis in the complex ν-plane by means of ''optimal'' Poisson weighted dispersion relations. The values obtained are compared with expected theoretical asymptotic behaviours and found not to be inconsistent with the possibility of a ''precocious asymptotism'' setting for imaginary ν-values

  19. Chiral symmetry and dispersion relations: from $\\pi \\pi$ scattering to hadronic light-by-light.

    Chiral symmetry provides strong constraints on hadronic matrix elements at low energy, which are most efficiently derived with chiral perturbation theory. As an effective quantum field theory the latter also accounts for rescattering or unitarity effects, albeit only perturbatively, via the loop expansion. In cases where rescattering effects are important it becomes necessary to go beyond the perturbative expansion, e.g. by using dispersion relations. A matching between the chiral and the dispersive representation provides in several cases results of high precision. I will discuss this approach with the help of a few examples, like $\\pi \\pi$ scattering (which has been tested successfully by CERN experiments like NA48/2 and DIRAC), $\\eta \\to 3 \\pi$ and the hadronic light-by-light contribution to $(g-2)_\\mu$. For the latter quantity the implementation of the dispersive approach has opened up the way to a model-independent calculation and the concrete possibility to significantly reduce the theoretical uncertain...

  20. Ivy signs on FLAIR images before and after STA-MCA anastomosis in patients with Moyamoya disease

    Background: Leptomeningeal high signal intensity (ivy sign) on fluid-attenuated inversion-recovery (FLAIR) MR imaging is one of the features of Moyamoya disease. However, the correlation between ivy sign and cerebral perfusion status has not been fully evaluated. Purpose: To characterize ivy sign on FLAIR images in Moyamoya disease and compare this finding with hemodynamic alterations on perfusion single-photon emission CT (SPECT) obtained before and after bypass surgery. Material and Methods: Sixteen patients with angiographically confirmed Moyamoya disease who underwent superficial temporal artery-middle cerebral artery (STA-MCA) anastomosis were included in the study. The presence of ivy sign on FLAIR images was classified as 'negative', 'minimal' and 'positive'. We evaluated the relationship between ivy sign and findings of SPECT, including cerebral vascular reserve (CVR) before and after surgery. Results: Minimal or positive ivy sign was seen in 13 (81%) of 16 patients, and 21 (66%) of 32 hemispheres. CVR in the areas with positive or minimal ivy sign was lower than that in the areas with negative ivy sign. After STA-MCA anastomosis, ivy sign disappeared or decreased in all 21 hemispheres demonstrating ivy sign. SPECT demonstrated apparent hemodynamic improvement in areas demonstrating disappearance or decrease of ivy sign. Conclusion: Ivy sign on FLAIR image is seen in areas with decreased cerebral perfusion. The sign is useful for non-invasive assessment of cerebral hemodynamic status before and after surgery

    Recently, we have seen interesting progress in the exploration of CP violation in B^0_d -> pi^+ pi^-: the measurements of mixing-induced CP violation by the BaBar and Belle collaborations are now in good agreement with each other, whereas the picture of direct CP violation is still unclear. Using the branching ratio and direct CP asymmetry of B^0_d -> pi^- K^+, this situation can be clarified. We predict A_CP^dir(B_d -> pi^+ pi^-) = -0.24+-0.04, which favours the BaBar result, and extract gamma=(70.0^{+3.8}_{-4.3})deg, which agrees with the unitarity triangle fits. Extending our analysis to other B -> pi K modes and B^0_s -> K^+ K^- with the help of the SU(3) flavour symmetry and plausible dynamical assumptions, we find that all observables with colour-suppressed electroweak penguin contributions are measured in excellent agreement with the Standard Model. As far as the ratios R_{c,n} of the charged and neutral B -> pi K branching ratios are concerned, which are sizeably affected by electroweak penguin contri...

    A search for the $C\\!P$-violating strong decays $\\eta \\to \\pi^+\\pi^-$ and $\\eta^\\prime(958) \\to \\pi^+\\pi^-$ has been performed using approximately $2.5 \\times 10^{7}$ events of each of the decays $D^+ \\to \\pi^+\\pi^+\\pi^-$ and $D_s^+ \\to \\pi^+\\pi^+\\pi^-$, recorded by the LHCb experiment. The data set corresponds to an integrated luminosity of 3.0 fb$^{-1}$ of $pp$ collision data recorded during LHC Run 1 and 0.3 fb$^{-1}$ recorded in Run 2. No evidence is seen for $D^+_{(s)} \\to \\pi^+ \\eta^{(\\prime)}$ with $\\eta^{(\\prime)} \\to \\pi^+\\pi^-$, and upper limits at 90% confidence level are set on the branching fractions, $\\mathcal{B}(\\eta \\to \\pi^+\\pi^-) < 1.6 \\times 10^{-5}$ and $\\mathcal{B}(\\eta^\\prime \\to \\pi^+\\pi^-) < 1.8 \\times 10^{-5}$. The limit for the $\\eta$ decay is comparable with the existing one, while that for the $\\eta^\\prime$ is a factor of three smaller than the previous limit.

  6. PI-103 and Quercetin Attenuate PI3K-AKT Signaling Pathway in T- Cell Lymphoma Exposed to Hydrogen Peroxide.

    Full Text Available Phosphatidylinositol 3 kinase-protein kinase B (PI3K-AKT pathway has been considered as major drug target site due to its frequent activation in cancer. AKT regulates the activity of various targets to promote tumorigenesis and metastasis. Accumulation of reactive oxygen species (ROS has been linked to oxidative stress and regulation of signaling pathways for metabolic adaptation of tumor microenvironment. Hydrogen peroxide (H2O2 in this context is used as ROS source for oxidative stress preconditioning. Antioxidants are commonly considered to be beneficial to reduce detrimental effects of ROS and are recommended as dietary supplements. Quercetin, a ubiquitous bioactive flavonoid is a dietary component which has attracted much of interest due to its potential health-promoting effects. Present study is aimed to analyze PI3K-AKT signaling pathway in H2O2 exposed Dalton's lymphoma ascite (DLA cells. Further, regulation of PI3K-AKT pathway by quercetin as well as PI-103, an inhibitor of PI3K was analyzed. Exposure of H2O2 (1mM H2O2 for 30min to DLA cells caused ROS accumulation and resulted in increased phosphorylation of PI3K and downstream proteins PDK1 and AKT (Ser-473 and Thr-308, cell survival factors BAD and ERK1/2, as well as TNFR1. However, level of tumor suppressor PTEN was declined. Both PI-103 & quercetin suppressed the enhanced level of ROS and significantly down-regulated phosphorylation of AKT, PDK1, BAD and level of TNFR1 as well as increased the level of PTEN in H2O2 induced lymphoma cells. The overall result suggests that quercetin and PI3K inhibitor PI-103 attenuate PI3K-AKT pathway in a similar mechanism.

    Strong final-state interactions create a pronounced cusp in {eta}'{yields}{eta}{pi}{sup 0}{pi}{sup 0} decays. We adapt and generalize the non-relativistic effective field theory framework developed for the extraction of {pi}{pi} scattering lengths from K{yields}3{pi} decays to this case. The cusp effect is predicted to have an effect of more than 8% on the decay spectrum below the {pi}{sup +}{pi}{sup -} threshold. (orig.)

    As first observed by the NA48/2 experiment at the CERN SPS, the $\\pi^{0}\\pi^{0}$ invariant mass ($M_{00}$) distribution from $K^{\\pm} \\rightarrow \\pi^{\\pm}\\pi^{0}\\pi^{0}$ decay shows a cusp-like anomaly at $M_{00}=2m_{+}$, where $m_{+}$ is the charged pion mass. An analysis to extract the $\\pi\\pi$ scattering lengths in the isospin $I=0$ and $I=2$ states, $a_{0}$ and $a_{2}$, respectively, has been recently reported. In the present work the Dalitz plot of this decay is fitted to a new empirical parameterization suitable for practical purposes, such as Monte Carlo simulations of $K^{\\pm} \\rightarrow \\pi^{\\pm}\\pi^{0}\\pi^{0}$ decays.

Their branching fractions are measured with respect to the corresponding Cabibbo favored decays, from which we obtain ${\\cal{B}}(\\bar{B}^0\\to D^+K^-\\pi^+\\pi^-)/{\\cal{B}}(\\bar{B}^0\\to D^+\\pi^-\\pi^+\\pi^-)=(5.9\\pm1.1\\pm0.5)\\times10^{-2}$ and ${\\cal{B}}(B^-\\to D^0K^-\\pi^+\\pi^-)/{\\cal{B}}(B^-\\to D^0\\pi^-\\pi^+\\pi^-)=(9.4\\pm1.3\\pm0.9)\\times10^{-2}$, where the uncertainties are statistical and systematic, respectively. The $B^-\\to D^0K^-\\pi^+\\pi^-$ decay is particularly interesting, as it can be used in a similar way to $B^-\\to D^0K^-$ to measure the CKM phase $\\gamma$.

    Science.gov (United States)

    Activating mutations involving the PI3K pathway occur frequently in human cancers. However, PI3K inhibitors primarily induce cell cycle arrest, leaving a significant reservoir of tumor cells that may acquire or exhibit resistance. We searched for genes that are required for the survival of PI3K mutant cancer cells in the presence of PI3K inhibition by conducting a genome scale shRNA-based apoptosis screen in a PIK3CA mutant human breast cancer cell. We identified 5 genes (PIM2, ZAK, TACC1, ZFR, ZNF565) whose suppression induced cell death upon PI3K inhibition.

    Diffractive dissociation of a {pi}{sup -} beam(190 GeV/c) on a proton target was measured at the COMPASS spectrometer. During a run in 2008, a large number of events with {pi}{sup -}{pi}{sup -}{pi}{sup +}{eta} in the final state was recorded. Partial wave analyses(PWA) of these data are being performed, concentrating on the kinematic domain of momentum transfer t' from 0.1 to 1.0 GeV{sup 2}/c{sup 2}. Subject of this thesis is the diffractive production of X from {pi}{sup -}p{yields}Xp with the subsequent decays X{yields}{pi}{sup -}f{sub 1} and f{sub 1}{yields}{pi}{sup -}{pi}{sup +}{eta}. Two different decays of the {eta} were selected: {eta}{yields}{pi}{sup -}{pi}{sup +}{pi}{sup 0}({gamma}{gamma}) and {eta}{yields}{gamma}{gamma}. A kinematic fitting routine was used to improve the data selection. In order to do the PWA, a Monte Carlo(MC) simulation is needed to account for the detector acceptance. In the mass-independent PWA the angular distributions of the real events are compared with the event distributions imposed on Monte Carlo(MC) events in order to determine the production amplitudes of different assumed partial waves in mass bins of 50 MeV/c{sup 2} of the invariant mass m{sub X} of X in the range 1.3 < m{sub X} < 3.0 GeV/c{sup 2}, by means of a maximum-likelihood-fit. Then a simplified mass-dependent fit of Breit-Wigner amplitudes has been applied to the distributions of production intensities as a function of m{sub X} in order to determine the contributions of known or presumed resonances. In the {pi}{sup -}f{sub 1} channel, we focus on the S, P and D wave i.e. orbital angular momentum L=0, 1, 2 between {pi}{sup -} and f{sub 1}. Significant intensity and phase motion are observed for the following J{sup PC}M{sup {epsilon}} combinations, where J, P, C, M and {epsilon} stand for the total angular momentum, parity and charge conjugation, total spin projection and reflectivity: 1{sup -+}1{sup +} (S wave), 1{sup ++}0{sup +} (P wave), 2{sup -+}0{sup +} (D

    Full Text Available Due to its sensitivity to deoxyhemoglobin, susceptibility weighted imaging (SWI enables the visualization of deep medullary veins (DMV in patients with acute stroke, which are difficult to depict under physiological circumstances. This study assesses the asymmetric appearance of prominent DMV as an independent predictor for stroke severity and outcome.SWI of 86 patients with acute middle cerebral artery (MCA stroke were included. A scoring system from 0 (no visible DMV to 3 (very prominent DMV was applied for both hemispheres separately. A difference of scores between ipsi- and contralateral side was defined as asymmetric (AMV+. Occurrence of AMV+ was correlated with the National Institute of Health Stroke Scale (NIHSS Score on admission and discharge, as well as the modified Rankin Scale (mRS at discharge. Ordinal regression analysis was used to evaluate NIHSS and mRS as predictors of stroke severity, clinical course of disease and outcome.55 patients displayed AMV+ while 31 did not show an asymmetry (AMV-. Median NIHSS on admission was 17 (11-21 in the AMV+ group and 9 (5-15 in the AMV- group (p = 0.001. On discharge median NIHSS was 11 (5-20 for AMV+ and 5 (2-14 for AMV- (p = 0.005. The median mRS at discharge was 4 (3-5 in the AMV+ group and 3 (1-4 in AMV- (p = 0.001. Odds ratio was 3.19 (95% CI: 1.24-8.21 for AMV+ to achieve a higher mRS than AMV- (p = 0.016.The asymmetric appearance of DMV on SWI is a fast and easily evaluable parameter for the prediction of stroke severity and can be used as an additional imaging parameter in patients with acute MCA stroke.

    Properties of the {pi}{pi}-interactions in hot and dense matter are studied within a nonperturbative and symmetry conserving approach. The pion and its chiral partner, the {sigma}-meson, are described within the linear {sigma} model and special attention is given to the conservation of the underlying chiral symmetry. The first part deals with the properties of pion and {sigma} in the vacuum, the further being the ''Goldstone''-boson of the theory, while the latter is a broad resonance. The results in the vacuum are tested against experimental results like {pi}{pi}-phase shifts as well as the mass and the width of the {sigma}-meson. Besides the propagator of the {sigma}-meson, the preservation of the chiral symmetry is explicitly examined and chiral Ward identities for the n-point functions of the theory are fulfilled. Furthermore the {pi}{pi}-scattering matrix is calculated and shown to be consistent with predictions from chiral perturbation theory. In the second part of this work the model is extended to finite temperature with special emphasis on the chiral phase transition. The transition temperature and the critical exponent {beta} are determined, and the influence of the temperature on the propagator of the s-meson as well as on the {pi}{pi}-scattering matrix is examined. The third part deals with the properties of pion and {sigma} in dense matter. Additional couplings like the ones to particle-hole excitations and short range repulsion have to be included to ensure stability at nuclear matter density. At zero three momentum one observes a strong downward shift of the {sigma}-mass accompanied by an accumulation of strength near the two-pion threshhold in the spectral function. Taking into account a finite three momentum for the {pi}{pi}-pair, respectively the {sigma}-meson, one observes a weakening of the aforementioned effect. Having thus developed a model for the {pi}{pi}-interaction at finite temperature and density, we try to describe

    A model in which Q/sub 1/ and Q/sub 2/ resonance contributions add coherently to a Gaussian background is shown to reproduce the mass dependence of the Jsup(P)=1/sup +/K*..pi.. and rhoK partial waves in K/sup + -/p..-->..K/sup + -/..pi../sup +/..pi../sup -/p at 13 GeV/c. Through a fit to the data, the mass and total width for Q/sub 1/ are found to be m=1289+-3+-(25) MeV, GAMMA=150+-9(+-70) MeV and for Q/sub 2/, m=1404+-3(+-10) MeV, GAMMA=142+-4(+-15) MeV, where estimated systematic errors are given in parentheses. While a significant background is required for the 1/sup +/K*..pi.. system, none is needed for the 1/sup +/rhoK system.

    Using a sample of 4.7 fb/sup -1/ integrated luminosity accumulated with the CLEO II detector at the Cornell Electron Storage Ring (CESR) , we investigate the mass spectrum and resonant structure in tau /sup -/ to K/sup -/ pi /sup +/ pi /sup -/ nu /sub tau / decays. We measure the relative fractions of K/sub 1/(1270) and K/sub 1/(1400) resonances in these decays, as well as the K/sub 1/ masses and widths. Our fitted K/sub 1/ resonances are somewhat broader than previous hadroproduction measurements, and in agreement with recent CERN LEP results from tau decay. The larger central value of our measured width supports models which attribute the small tau /sup -/ to K/sup -/ pi /sup +/ pi /sup -/ nu /sub tau / branching fraction to larger K/sub 1/ widths than are presently tabulated. We also determine the K/sub a/-K/sub b/ mixing angle theta /sub K/. (22 refs) .

  1. Decreased expression of GST pi is correlated with a poor prognosis in human esophageal squamous carcinoma

    Directory of Open Access Journals (Sweden)

    Wang Junsheng

    2010-07-01

    Full Text Available Abstract Background Glutathione S-transferase pi (GST pi is a subgroup of GST family, which provides cellular protection against free radical and carcinogenic compounds due to its detoxifying function. Expression patterns of GST pi have been studied in several carcinomas and its down-regulation was implicated to be involved in malignant transformation in patients with Barrett's esophagus. However, neither the exact role of GST pi in the pathogenesis nor its prognostic impact in squamous esophageal carcinoma is fully characterized. Methods Immunohistochemistry was used to investigate GST pi expression on 153 archival squamous esophageal carcinoma specimens with a GST pi monoclonal antibody. Statistic analyses were performed to explore its association with clinicopathological factors and clinical outcome. Results The GST pi expression was greatly reduced in tissues of esophageal carcinomas compared to adjacent normal tissues and residual benign tissues. Absent of GST pi protein expression in cytoplasm, nuclear and cytoplasm/nucleus was found in 51%, 64.7% and 48% of all the carcinoma cases, respectively. GST pi deficiency in cytoplasm, nucleus and cytoplasm/nucleus was significantly correlated to poor differentiation (p p p p p = 0.004, respectively and cytoplasm/nucleus (p = 0.017 and p = 0.031, respectively. In univariate analysis, absent of GST pi protein expression in cytoplasm, nucleus and cytoplasm/nucleus was significantly associated with a shorter overall survival (p p p p Conclusions Our results show that GST pi expression is down regulated in the squamous esophageal carcinoma, and that the lack of GST pi expression is associated with poor prognosis. Therefore, deficiency of GST pi protein expression may be an important mechanism involved in the carcinogenesis and progression of the squamous esophageal carcinoma, and the underlying mechanisms leading to decreased GST pi expression deserve further investigation.

    Collateral blood flow is accepted as a predictive factor of tissue fate in ischemic stroke. Thus, we aimed to evaluate a new method derived from MR perfusion source images to assess collateral flow in patients with ICA/MCA occlusions. A total of 132 patients of the prospective 1000+ study were examined. MR perfusion source images were assessed according to Δimg n = img n + 1 - img n - 1 using the five-grade Higashida collateral flow rating system. Higashida scores were correlated to mismatch (MM) volume, mismatch ratio, day 6 FLAIR lesion volumes and day 90 mRS. Patients with Higashida scores 3 and 4 had significantly lower admission NIHSS, smaller FLAIR day 6 lesion volumes (p < 0.001) and higher rates of better long-term outcome (mRS 0-2, p = 0.002). There was a linear trend for the association of Higashida grade 1 (p = 0.002) and 2 (p = 0.001) with unfavourable outcome (day 90 mRS 3-6), but no significant association was found for MM volume, MM ratio and day 90 mRS. Inter-rater agreement was 0.58 (95 % CI 0.43-0.73) on day 1, 0.70 (95 % CI 0.58-0.81) on day 2. sMRP-SI Higashida score offers a non-invasive collateral vessel and tissue perfusion assessment of ischemic tissue. The predictive value of Higashida rating proved superior to MM with regard to day 90 mRS. (orig.)

    A study of the flavor-changing neutral current radiative $B^{\\pm} \\to K^{\\pm}\\pi^{\\mp}\\pi^{\\pm}\\gamma$ decays performed using data collected in proton-proton collisions with the LHCb detector at $7$ and $8\\,$TeV center-of-mass energies is presented. In this sample, corresponding to an integrated luminosity of $3\\,\\text{fb}^{-1}$, nearly $14\\,000$ signal events are reconstructed and selected, containing all possible intermediate resonances with a $K^{\\pm}\\pi^{\\mp}\\pi^{\\pm}$ final state in the $[1.1, 1.9]$\\,GeV/$c^{2}$ mass range. The distribution of the angle of the photon direction with respect to the plane defined by the final-state hadrons in their rest frame is studied in intervals of $K^{\\pm}\\pi^{\\mp}\\pi^{\\pm}$ mass and the asymmetry between the number of signal events found on each side of the plane is obtained. The first direct observation of the photon polarization in the $b \\to s\\gamma$ transition is reported with a significance of $5.2\\,\\sigma$.

    The K{sub S{yields}{pi}}{sup +{pi}-}e{sup +}e{sup -} decay mode was investigated using the data collected in 2002 by the NA48/1 Collaboration. With about 23 k K{sub S{yields}{pi}}{sup +{pi}-}e{sup +}e{sup -} events and 59 k K{sub L{yields}{pi}}{sup +{pi}-{pi}}{sub D}{sup 0} normalization decays, the K{sub S{yields}{pi}}{sup +{pi}-}e{sup +}e{sup -} branching ratio relative to the K{sub L{yields}{pi}}{sup +{pi}-{pi}}{sub D}{sup 0} one was determined to be BR(K{sub S{yields}{pi}}{sup +{pi}-}e{sup +}e{sup -})/BR(K{sub L{yields}{pi}}{sup +{pi}-{pi}}{sub D}{sup 0})=(3.28{+-}0.06{sub stat{+-}}0.04{sub syst})x10{sup -2}. This result was used to set the upper limit |g{sub E1}/g{sub BR}|<3.0 at 90% CL on the presence, in the decay amplitude, of an E1 direct emission (g{sub E1}) term relative to the dominant inner bremsstrahlung (g{sub BR}) term. The CP-violating asymmetry A{sub {phi}} in the sin{phi}cos{phi} distribution of K{sub S{yields}{pi}}{sup +{pi}-}e{sup +}e{sup -} events, where {phi} is the angle between the {pi}{sup +{pi}-} and the e{sup +}e{sup -} decay planes in the kaon centre of mass, was found to be A{sub {phi}=}(-0.4{+-}0.8)%, consistent with zero. These results are in good agreement with a description of the K{sub S{yields}{pi}}{sup +{pi}-}e{sup +}e{sup -} decay amplitude dominated by the CP-even inner bremsstrahlung process.

    The K_L -> pi+pi-e+e- and K_S -> pi+pi-e+e- decay modes have been studied in detail using the NA48 detector at CERN SPS. Based on the data collected during the 1998 and 1999 run periods, a sample of 1162 K_L -> pi+pi-e+e- candidates has been observed with an expected background level of 36.9 events, yielding the branching ratio measurement BR(K_L -> pi+pi-e+e-)=(3.08+-0.20)x10^-7. The distribution of events in the sin\\phicos\\phi variable, where \\phi is the angle between the pi+pi- and the e+e- decay planes in the kaon centre of mass, is found to exhibit a large CP-violating asymmetry with the value A_\\phi(14.2+-3.6)%. For the K_S -> pi+pi-e+e- decay channel, 621 candidates have been identified in the 1999 data sample with an estimated background contribution of 0.7 event. The corresponding branching ratio has been determined to be BR(K_S -> pi+pi-e+e-)=(4.71+-0.32)x10^-5. The combined value of this measurement with the published 1998 result id BR(K_S -> pi+pi-e+e-)=4.69+-0.30)x10^-5. No asymmetry is observed ...

    Demand of groundwater resources has increased manifold with population expansion as well as with the advent of modern civilization. Assessment, planning and management of groundwater resource are becoming crucial and extremely urgent in recent time. The study area belongs to Kashipur block, Purulia district, West Bengal. The area is characterized with dry climate and hard rock terrain. The objective of this study is to delineate groundwater potential zone for the assessment of groundwater availability using remote sensing, GIS and MCA techniques. Different thematic layers such as hydrogeomorphology, slope and lineament density maps have been transformed to raster data in TNT mips pro2012. To assign weights and ranks to different input factor maps, multi-influencing factor (MIF) technique has been used. The weights assigned to each factor have been computed statistically. Weighted index overlay modeling technique was used to develop a groundwater potential zone map with three weighted and scored parameters. Finally, the study area has been categorized into four distinct groundwater potential zones—excellent 1.5% (6.45 sq. km), good 53% (227.9 sq. km), moderate 45% (193.5 sq. km.) and poor 0.5% (2.15 sq. km). The outcome of the present study will help local authorities, researchers, decision makers and planners in formulating proper planning and management of groundwater resources in different hydrogeological situations.

    Most of our electronic equipment has buffer, thus this make buffer as one of importance in electronic gadget. This paper introduced Single Ended Input Differential Output (SEIDO) buffer to predict the bias at approximately 2.5 V. For this purpose, the input range between -1 mV to 4 V was implemented. The software used to cascade SEIDO buffer is called LTspice IV; an open source software developed by Linear Technology Incorporation. The component involve in this development was Operational Amplifier (OP AMP) AD826 from Analog Devices Incorporation, capacitor and resistor. Kirchhoffs Current Law and Kirchhoffs Voltage Law was applied to calculated voltage gain and biasing voltage. All design has been verified by LTspice IV. The result produced from simulation was between -0.3 V to 6.3 V with bias roughly at 2.5 V. These results prove that it was capable to drive Analog Digital Converter (ADC) that can subsequently apply for Multichannel Analyzer (MCA). (author)

    The five ternary intermetallic compounds M 2 Pt 6 Al 15 (M=Ca, Sc, Y, La, Lu) were prepared from the elements by arc-melting. The crystal structure was determined via single crystal X-ray diffraction. The title compounds crystallize in a superstructure of the RE 0.67 Pt 2 Al 5 type structure (P6 3 /mmc) in the monoclinic crystal system with space group P12 1 /m1 (Sc 2 Pt 6 Al 15 : a=734.19(2), b=1628.96(10), c=734.19(2) pm, β=119.999(3) ; wR=0.0356, 3034 F 2 values, 68 variables). The superstructure can be derived by the superspace formalism using (3+2)D or (3+1)D interpretations of the diffraction data. The structural relation to the subcell structure is discussed on the basis of a group-subgroup scheme. In the crystal structure strongly bonded [Pt 2 Al 4 ] δ- slabs are alternatingly stacked with ordered layers containing M atoms and Al 3 triangles.

    A new analysis of the channel pp to K/sup +or-/K/sub S//sup 0/ pi /sup -or+/ pi /sup +/ pi /sup -/ with 5400 events has been performed. The preliminary results indicate that data cannot be fitted with a single pseudoscalar state in the E/ iota region. The hypothesis with two states improves significantly the data description, but two solutions with different mass values for the state of higher mass have been found. (4 refs).

    Exposure of synaptosomes to microwave radiation at a power density of 10 mW/sq cm or more produced stimulation of the 32 Pi-incorporation into phosphoinositides. The extent of 32 Pi incorporation was found to be much more pronounced in phosphatidylinositol-4-phosphate (PIP), and phosphatidylinositol-4,5-bisphosphate (PIP 2 ) as compared to phosphatidylinositol (PI) and phosphatidic acid (PA). Other lipids were also found to incorporate 32 Pi but no significant changes in their labeling were seen after exposure to microwave radiation. Inclusion of 10 mM lithium in the medium reduced the basal labeling of PIP 2 , PIP and PI and increased PA labeling. Li + also inhibited the microwave stimulated PIP 2 , PIP and PI labeling but had no effect on PA labeling. Calcium inophore, A 23187 , inhibited the basal and microwave stimulated 32 Pi labeling of PIP and PIP 2 , stimulated basal labeling of PA and PI and had no effect on microwave stimulated PA and PI labeling. Calcium chelator, EGTA, on the other hand, had no effect on basal labeling of PA and PI, stimulated basal PIP and PIP 2 labeling but did not alter microwave stimulated labeling of these lipids. Exposure of synaptosomes to microwave radiation did not alter the chemical concentration of phosphoinositides indicating that the turnover of these lipids was altered. These results suggest that low frequency microwave radiation alter the metabolism of inositol phospholipids by enhancing their turnover and thus may affect the transmembrane signalling in the nerve endings.

  18. Radiative corrections to the charged pion-pair production process {pi}{sup -}{gamma} {yields} {pi}{sup +}{pi}{sup -}{pi}{sup -} at low energies

    We calculate the one-photon loop radiative corrections to the charged pion-pair production process {pi}{sup -}{gamma} {yields} {pi}{sup +}{pi}{sup -}{pi}{sup -}. In the low-energy region this reaction is governed by the chiral pion-pion interaction. The pertinent set of 42 irreducible photon-loop diagrams is calculated by using the package FeynCalc. Electromagnetic counterterms with two independent low-energy constants k{sub 1} and k{sub 2} are included in order to remove the ultraviolet divergences generated by the photon loops. Infrared finiteness of the virtual radiative corrections is achieved by including soft photon radiation below an energy cut-off {Lambda}. The purely electromagnetic interaction of the charged pions mediated by one-photon exchange is also taken into account. The radiative corrections to the total cross section (in the isospin limit) vary between +10% close to threshold and about -1% at a center-of-mass energy of 7m{sub {pi}}. The largest contribution comes from the simple one-photon exchange. Radiative corrections to the {pi}{sup +}{pi}{sup -} and {pi}{sup -}{pi}{sup -} mass spectra are studied as well. The Coulomb singularity of the final-state interaction produces a kink in the dipion mass spectra. The virtual radiative corrections to elastic {pi}{sup -}{pi}{sup -} scattering are derived additionally. (orig.)

As the value of the above lifetime of order 10$ ^- ^{1} ^{5} $s is dictated by a strong interaction at low energy, the precise measurement of this quantity enables to determine a combination of S-wave pion scattering lengths to 5\\%. Pion scattering lengths have been calculated in the framework of chiral perturbation theory and values predicted at the same level of accuracy have, up to now, never been confronted with accurate experimental data. Such a measurement would submit the understanding of chiral symmetry breaking of QCD to a crucial test.

  20. Nonlinear PI Control with Adaptive Interaction Algorithm for Multivariable Wastewater Treatment Process

    S. I. Samsudin

    2014-01-01

    Full Text Available The wastewater treatment plant (WWTP is highly known with the nonlinearity of the control parameters, thus it is difficult to be controlled. In this paper, the enhancement of nonlinear PI controller (ENon-PI to compensate the nonlinearity of the activated sludge WWTP is proposed. The ENon-PI controller is designed by cascading a sector-bounded nonlinear gain to linear PI controller. The rate variation of the nonlinear gain kn is automatically updated based on adaptive interaction algorithm. Initiative to simplify the ENon-PI control structure by adapting kn has been proved by significant improvement under various dynamic influents. More than 30% of integral square error and 14% of integral absolute error are reduced compared to benchmark PI for DO control and nitrate in nitrogen removal control. Better average effluent qualities, less number of effluent violations, and lower aeration energy consumption resulted.

    Glutathione S-transferase pi (GST pi) is a subgroup of GST family, which provides cellular protection against free radical and carcinogenic compounds due to its detoxifying function. Expression patterns of GST pi have been studied in several carcinomas and its down-regulation was implicated to be involved in malignant transformation in patients with Barrett's esophagus. However, neither the exact role of GST pi in the pathogenesis nor its prognostic impact in squamous esophageal carcinoma is fully characterized. Immunohistochemistry was used to investigate GST pi expression on 153 archival squamous esophageal carcinoma specimens with a GST pi monoclonal antibody. Statistic analyses were performed to explore its association with clinicopathological factors and clinical outcome. The GST pi expression was greatly reduced in tissues of esophageal carcinomas compared to adjacent normal tissues and residual benign tissues. Absent of GST pi protein expression in cytoplasm, nuclear and cytoplasm/nucleus was found in 51%, 64.7% and 48% of all the carcinoma cases, respectively. GST pi deficiency in cytoplasm, nucleus and cytoplasm/nucleus was significantly correlated to poor differentiation (p < 0.001, p < 0.001 and p < 0.001, respectively). UICC stage and T stage were found significantly correlated to negative expression of GST pi in cytoplasm (p < 0.001 and p = 0.004, respectively) and cytoplasm/nucleus (p = 0.017 and p = 0.031, respectively). In univariate analysis, absent of GST pi protein expression in cytoplasm, nucleus and cytoplasm/nucleus was significantly associated with a shorter overall survival (p < 0.001, p < 0.001 and p < 0.001, respectively), whereas only GST pi cytoplasmic staining retained an independent prognostic significance (p < 0.001) in multivariate analysis. Our results show that GST pi expression is down regulated in the squamous esophageal carcinoma, and that the lack of GST pi expression is associated with poor prognosis. Therefore

    Eu 2+ doped silicate glasses were prepared of the system 52SiO 2 -48MO: xEu 2+ (in molar ratio, M=Ca, Sr, Ba; x=1, 3, 5, 7, 9) by a high temperature melt-quenching method in a reducing atmosphere. Glass ceramics containing MSiO 3 :Eu 2+ (M=Ca, Sr, Ba) nano-phosphors were obtained after the heat treatment of the glass samples. The excitation, emission spectra and lifetime decay curves of 4f 6 5d 1 →4f 7 of Eu 2+ were measured and interpreted with respect to their crystal structures and multi-site occupations of divalent europium in the hosts. Their excitation bands mainly extend from 450 to 250 nm, which is adaptable to the main emission region of the UV LED chip. With UV light excitation, the Eu 2+ emission in CaSiO 3 , SrSiO 3 and BaSiO 3 shows blue, green and yellow colors centered at 440, 505 and 555 nm, respectively. The critical Eu 2+ concentration was studied and determined to be x=5 for both CaSiO 3 and SrSiO 3 and x=7 for BaSiO 3 phosphors. The results show that the Eu 2+ doped glass ceramic phosphors containing MSiO 3 (M=Ca, Sr, Ba) nano-crystals can be used as potential matrix materials for a high power white LED pumped by the UV LED chip. - Highlights: → Glass ceramic containing MSiO 3 :Eu 2+ (M=Ca, Sr, Ba) phosphors prepared. → Derived phosphors emit intensively blue, green and yellow colors. → Their luminescence properties and crystal structures have been investigated. → Concentration quenching effects observed and analyzed. → Potential application for UV chip exciting white LED evaluated.

    The multichannel analyzer is the heart of most experimental measurements. Today, it becomes popular and convenient. It can play a role of getting, processing data and easily interfacing to PC. Some standard-alone multichannel analysis systems can be replaced by Add-on MCA card. Especially, MCA card is necessary for application in nuclear physics research. The main aim of this sub-project is to focus on a design and construction of an 8K-MCA Add-on served for studying nuclear structure, for development of Gamma spectroscopy system, and for a production of low-cost electronics instruments as well. Some experimental results were obtained through the aforementioned card combining with other needed functional analog units. A multichannel data processing (MCD) circuit for nuclear spectroscopy application was developed using a field programmable gate arrays (FPGA) as the central processing element. In addition to the first role, A 13-bit analog-to-digital converter (8k ADC) circuit for nuclear spectroscopy application was also developed using a successive approximation ADC with a control of FPGA technology. The FPGA operates a program that builds the distributed functions of data collected by the ADC and then corrects the ADC differential non-linearity (DNL) via the sliding scale method. The acquisition routine runs in 3.7μ s. the conversion time is approximated 2.2μ s, and the integral non-linearity ≤ 0.14%. (author)

    A search is made for the highly-suppressed B meson decays $B^{+}\\rightarrow K^{+}K^{+}\\pi^{-}$ and $B^{+}\\rightarrow \\pi^{+}\\pi^{+}K^{-}$ using a data sample corresponding to an integrated luminosity of 3.0 $fb^{-1}$ collected by the LHCb experiment in proton-proton collisions at centre-of-mass energies of 7 and 8 TeV. No evidence is found for the decays, and upper limits at 90\\% confidence level are determined to be $\\mathcal{B}(B^{+}\\rightarrow K^{+}K^{+}\\pi^{-}) < 1.1\\times 10^{-8}$ and $\\mathcal{B}(B^{+}\\rightarrow \\pi^{+}\\pi^{+}K^{-}) < 4.6\\times 10^{-8}$.

  6. A study of $CP$ violation in $B^\\mp \\rightarrow Dh^\\mp$ ($h=K,\\pi$) with the modes $D \\rightarrow K^\\mp \\pi^\\pm \\pi^0$, $D \\rightarrow \\pi^+\\pi^-\\pi^0$ and $D \\rightarrow K^+K^-\\pi^0$

    An analysis of the decays of $B^\\mp \\rightarrow D K^\\mp$ and $B^\\mp \\rightarrow D \\pi^\\mp $ is presented in which the $D$ meson is reconstructed in the three-body final states $K^\\mp \\pi^\\pm \\pi^0$, $\\pi^+ \\pi^- \\pi^0$ and $K^+ K^- \\pi^0$. Using data from LHCb corresponding to an integrated luminosity of 3.0~fb$^{-1}$ of $pp$ collisions, measurements of several $CP$ observables are performed. First observations are obtained of the suppressed ADS decay $B^\\mp \\rightarrow [\\pi^\\mp K^\\pm \\pi^0]_D \\pi^\\mp$ and the quasi-GLW decay $B^\\mp \\rightarrow [K^+ K^- \\pi^0]_D \\pi^\\mp$. The results are interpreted in the context of the unitarity triangle angle $\\gamma$ and related parameters.

    We reported increased levels of Phosphatidyl Inositol synthase (PI synthase), (enzyme that catalyses phosphatidyl inositol (PI) synthesis-implicated in intracellular signaling and regulation of cell growth) in smokeless tobacco (ST) exposed oral cell cultures by differential display. This study determined the clinical significance of PI synthase overexpression in oral squamous cell carcinoma (OSCC) and premalignant lesions (leukoplakia), and identified the downstream signaling proteins in PI synthase pathway that are perturbed by smokeless tobacco (ST) exposure. Tissue microarray (TMA) Immunohistochemistry, Western blotting, Confocal laser scan microscopy, RT-PCR were performed to define the expression of PI synthase in clinical samples and in oral cell culture systems. Significant increase in PI synthase immunoreactivity was observed in premalignant lesions and OSCCs as compared to oral normal tissues (p = 0.000). Further, PI synthase expression was significantly associated with de-differentiation of OSCCs, (p = 0.005) and tobacco consumption (p = 0.03, OR = 9.0). Exposure of oral cell systems to smokeless tobacco (ST) in vitro confirmed increase in PI synthase, Phosphatidylinositol 3-kinase (PI3K) and cyclin D1 levels. Collectively, increased PI synthase expression was found to be an early event in oral cancer and a target for smokeless tobacco

    The K sub L-> pi sup +pi sup - e sup + e sup - and K sub S-> pi sup +pi sup - e sup + e sup - decay modes have been studied in detail using the NA48 detector at the CERN SPS. Based on the data collected during the 1998 and 1999 run periods, a sample of 1162 K sub L-> pi sup +pi sup - e sup + e sup - candidates has been observed with an expected background level of 36.9 events, yielding the branching ratio measurement BR(K sub L -> pi sup +pi sup - e sup + e sup -)=(3.08+-0.20) x 10 sup - sup 7. The distribution of events in the sin phi cos phi variable, where phi is the angle between the pi sup +pi sup - and the e sup + e sup - decay planes in the kaon centre of mass, is found to exhibit a large CP-violating asymmetry with the value A subphi=(14.2+-3.6)%. For the K sub S-> pi sup +pi sup - e sup + e sup - decay channel, 621 candidates have been identified in the 1999 data sample with an estimated background contribution of 0.7 event. The corresponding branching ratio has been determined to be BR(K sub S-> pi ...

    pion mass difference generates a pronounced cusp in K->3{pi} decays. As has recently been pointed out by Cabibbo and Isidori, an accurate measurement of the cusp may allow one to pin down the S-wave {pi}{pi} scattering lengths to high precision. Here, we present and illustrate an effective field theory framework that allows one to determine the structure of this cusp in a straightforward manner. The strictures imposed by analyticity and unitarity are respected automatically.

    The proposed experiment makes use of the FRAMM spectrometer (experiments NA1 and NA7). The aim of the experiment is to study the reaction $\\pi^{-}$Pb $\\rightarrow \\pi^{-}\\pi^{0}$Pb via Primakoff effect in order to measure the radiative decay width $\\Gamma(\\rho^{-} \\rightarrow \\pi^{-}\\gamma)$ of the $\\rho^{-}$meson and to measure the cross-section of the reaction at threshold. \\\\\\\\The controversial data on $\\Gamma(\\rho^{-} \\rightarrow \\pi^{-}\\gamma)$ and the theoretical importance of this process justify a high statistics study of the reaction in the $\\rho^{-}$ region.\\\\\\\\ The physical interest of the measurement of the $\\pi^{-}\\pi^{0}$ production cross-section at threshold is to check the validity of the low energy theorem for the $\\gamma \\rightarrow 3\\pi$ vertex (Adler, Bell and Jackiw anomalies) and to obtain a direct determination

    The confirmation of the Cabibbo-suppressed charm baryon decay mode {Lambda}{sub c}{sup +} {yields} p{pi}{sup +}{pi}{sup -} is reported. All data analyzed are from SELEX, a fixed target experiment at Fermilab that took data during 1996 and 1997, mainly with a 600 GeV/c {Sigma}{sup -} beam. The branching ratio of the Cabibbo-suppressed decay mode {Lambda}{sub c}{sup +} {yields} p{pi}{sup +}{pi}{sup -} relative to the Cabibbo-favored mode {Lambda}{sub c}{sup +} {yields} pK{sup -}{pi}{sup +} is measured to be: {Gamma}({Lambda}{sub c}{sup +} {yields} p{pi}{sup +}{pi}{sup -})/{Gamma}({Lambda}{sub c}{sup +} {yields} pK{sup -}{pi}{sup +}) = 0.103 {+-} 0.022.

    Phosphoinositides and their metabolizing enzymes are involved in Aβ 42 metabolism and Alzheimer's disease pathogenesis. In yeast and mammals, Eighty-five requiring 3 (EFR3), whose Drosophila homolog is Rolling Blackout (RBO), forms a plasma membrane-localized protein complex with phosphatidylinositol-4-kinase Type IIIα (PI4KIIIα) and a scaffold protein to tightly control the level of plasmalemmal phosphatidylinositol-4-phosphate (PI 4 P). Here, we report that RBO binds to Drosophila PI4KIIIα, and that in an Aβ 42 -expressing Drosophila model, separate genetic reduction of PI4KIIIα and RBO, or pharmacological inhibition of PI4KIIIα ameliorated synaptic transmission deficit, climbing ability decline, premature death, and reduced neuronal accumulation of Aβ 42 Moreover, we found that RBO-PI4KIIIa downregulation increased neuronal Aβ 42 release and that PI4P facilitated the assembly or oligomerization of Aβ 42 in/on liposomes. These results indicate that RBO-PI4KIIIa downregulation facilitates neuronal Aβ 42 release and consequently reduces neuronal Aβ 42 accumulation likely via decreasing Aβ 42 assembly in/on plasma membrane. This study suggests the RBO-PI4KIIIα complex as a potential therapeutic target and PI4KIIIα inhibitors as drug candidates for Alzheimer's disease treatment. SIGNIFICANCE STATEMENT Phosphoinositides and their metabolizing enzymes are involved in Aβ 42 metabolism and Alzheimer's disease pathogenesis. Here, in an Aβ 42 -expressing Drosophila model, we discovered and studied the beneficial role of downregulating RBO or its interacting protein PI4KIIIα-a protein that tightly controls the plasmalemmal level of PI 4 P-against the defects caused by Aβ 42 expression. Mechanistically, RBO-PI4KIIIα downregulation reduced neuronal Aβ 42 accumulation, and interestingly increased neuronal Aβ 42 release. This study suggests the RBO-PI4KIIIα complex as a novel therapeutic target, and PI4KIIIα inhibitors as new drug candidates. Copyright

    A modified Chew-Low extrapolation procedure is applied to the reaction pi /sup -/p to Delta /sup ++/ pi /sup -/ pi /sup -/ to extract the I=2 pi pi elastic cross sections from threshold to 1260 MeV. The predictions of the one-pion-exchange model are used to estimate the contributions from background processes of the type pi /sup -/p to Delta /sup 0/ rho /sup 0/. The moments of the pi /sup -/ pi /sup -/ angular distribution are also extrapolated to the pion pole and a phase shift analysis performed. The s-wave inelasticity is constrained using information on the inelastic cross section coming from six-body final states. The magnitude of the s-wave phase shift at the K/sup 0/ mass is found to be 7.2 degrees +or-1.0 degrees , increasing to 26.2 degrees +or-2.5 degrees at 1 GeV. d- and g-waves contribute above about 900 MeV, but the corresponding phase shifts are small compared with the s-wave. All three phase shifts have the same sign. (24 refs).

    Charm meson oscillations are observed in a time-dependent analysis of the ratio of $D^0\\to K^+\\pi^-\\pi^+\\pi^-$ to $D^0\\to K^-\\pi^+\\pi^-\\pi^+$ decay rates, using data corresponding to an integrated luminosity of $3.0\\,{\\rm fb}^{-1}$ recorded by the LHCb experiment. The measurements presented are sensitive to the phase-space averaged ratio of doubly Cabibbo-suppressed to Cabibbo-favoured amplitudes $r_{D}^{K3\\pi}$ and the product of the coherence factor $R_{D}^{K3\\pi}$ and a charm mixing parameter $y^{'}_{K3\\pi}$. The constraints measured are $r_{D}^{K3\\pi}=(5.67 \\pm 0.12)\\times10^{-2}$, which is the most precise determination to date, and $R_{D}^{K3\\pi} \\cdot y^{'}_{K3\\pi} = (0.3 \\pm 1.8)\\times 10^{-3}$, which provides useful input for determinations of the CP-violating phase $\\gamma$ in $B^\\pm \\to D K^\\pm, D \\to K^\\mp\\pi^\\pm\\pi^\\mp\\pi^\\pm$ decays. The analysis also gives the most precise measurement of the $D^0\\to K^+\\pi^-\\pi^+\\pi^-$ branching fraction, and the first observation of $D^0-\\bar D^0$ oscillations...

  1. Time-dependent Dalitz-Plot Analysis of the Charmless Decay B^0 -> K^0S Pi Pi- at BABAR

    Energy Technology Data Exchange (ETDEWEB)

    Ilic, J

    2009-10-17

    A time-dependent amplitude analysis of B{sup 0} {yields} K{sub S}{sup 0}{pi}{sup +}{pi}{sup -} decays is performed in order to extract the CP violation parameters of f{sub 0}(980)K{sub S}{sup 0} and {rho}{sup 0}(770)K{sub S}{sup 0} and direct CP asymmetries of K*{sup +}(892){pi}{sup -}. The results are obtained from the final BABAR data sample of (465 {+-} 5)10{sup 6} B{bar B} decays, collected with the BABAR detector at the PEP-II asymmetric-energy B factory at SLAC. The time dependent CP asymmetry for f{sub 0}(980)K{sub S}{sup 0} and {rho}{sup 0}(770)K{sub S}{sup 0} are measured to be S(f{sub 0}(980)K{sub S}{sup 0}) = -0.97 {+-} 0.09 {+-} 0.01 {+-} 0.01, and S({rho}{sup 0}(770)K{sub S}{sup 0}) = 0.67 {+-} 0.20 {+-} 0.06 {+-} 0.04, respectively. In decays to K*{sup +}(892){pi}{sup -} the direct CP asymmetry is found to be A{sub CP}(K*{sup {+-}}(892){pi}{sup {-+}}) = -0.18 {+-} 0.10 {+-} 0.04 {+-} 0.00. The relative phases between B{sup 0} {yields} K*{sup +}(892){pi}{sup -} and {bar B}{sup 0} {yields} K*{sup -}(892){pi}{sup +}, relevant for the extraction of the unitarity triangle angle {gamma}, is measured to be {Delta}{phi}(K*(892){pi}) = (34.9 {+-} 23.1 {+-} 7.5 {+-} 4.7){sup o}, where uncertainties are statistical, systematic and model-dependent, respectively. Fit fractions, direct CP asymmetries and the relative phases of different other resonant modes have also been measured. A new method for extracting longitudinal shower development information from longitudinally unsegmented calorimeters is also presented. This method has been implemented as a part of the BABAR final particle identification algorithm. A significant improvement in low momenta muon identification at BABAR is obtained.

  2. Easy as Pi: A Network Coding Raspberry Pi Testbed

    Directory of Open Access Journals (Sweden)

    2016-10-01

    Full Text Available In the near future, upcoming communications and storage networks are expected to tolerate major difficulties produced by huge amounts of data being generated from the Internet of Things (IoT. For these types of networks, strategies and mechanisms based on network coding have appeared as an alternative to overcome these difficulties in a holistic manner, e.g., without sacrificing the benefit of a given network metric when improving another. There has been recurrent issues on: (i making large-scale deployments akin to the Internet of Things; (ii assessing and (iii replicating the obtained results in preliminary studies. Therefore, finding testbeds that can deal with large-scale deployments and not lose historic data in order to evaluate these mechanisms are greatly needed and desirable from a research perspective. However, this can be hard to manage, not only due to the inherent costs of the hardware, but also due to maintenance challenges. In this paper, we present the required key steps to design, setup and maintain an inexpensive testbed using Raspberry Pi devices for communications and storage networks with network coding capabilities. This testbed can be utilized for any applications requiring results replicability.

    The proposed experiment is a further development of the DIRAC experiment already running at CERN PS. Up to now more than 21000 $\\pi^+\\pi^-$ pairs originated from the $\\pi^+\\pi^-$ atom ($A_{2\\pi}$) breakup were identified and the overall accuracy of the $A_{2\\pi}$ lifetime is about 9% in accordance with the DIRAC proposal. This measurement allowed to extract the difference $|a_0-a_2|$ of $s$-wave $\\pi\\pi$-scattering length with accuracy of 4.3%. The observation of long-lived (metastable) $A_{2\\pi}$ states will be performed with the same setup. This observation opens a possibility to measure the energy difference between $ns$ and $np$ states and to determine the value of another combination $2a_0+a_2$ of $\\pi\\pi$ scattering length in a model-independent way. In combination with the first measurement it allows to get $a_0$ and $a_2$ separately. An additional measurement of the multiple scattering angles in different materials with accuracy better than 1% will be performed in parallel with the observation. This m...

    The n -> pi* and pi -> pi* vertical electronic transitions of acetone with two and four H2O which correspond to a first solvation shell are considered. By using localized orbitals, and thanks to the MRCI approach which permits to know the wave function, the role of the various solvent molecules...... is analysed in details. Distinguishing the solvent molecules allows one to consider them at different calculation levels. The methodology is to compare the spectra obtained with four H2O, with two H2O either in the acetone plane or in a perpendicular plane and when they are completely or partly frozen....

  6. Effect of Ca2+ overload on phosphoinositide (PI) metabolism in cardiac muscle

    International Nuclear Information System (INIS)

    Otani, H.; Otani, H.; Engelman, R.M.; Das, D.K.

    1986-01-01

    The investigated the relationship between Ca 2+ load and PI metabolism in isolated rat papillary muscle labeled with [ 3 H]inositol. Increase in [Ca 2+ ]/sub o/ from 0-3.6 mM reduced the incorporation of [ 3 H] inositol into PI moderately and increased the resting tension slightly. The incorporation of the label into PI was unchanged by 10 μm A-23187 at 1.8 mM [Ca 2+ ]/sub o/ that increased the contractility by 70% without a significant change in the resting tension. However, either 10.8 mM [Ca 2+ ]/sub o/ or 0.3 mM ouabain at 1.8 mM [Ca 2+ ]/sub o/ markedly decreased the PI labeling with corresponding increase in the resting tension while inclusion of excess EGTA greatly enhanced the radioactivity in PI. Determination of the PI breakdown and the inositol phosphates production by pulse-chase experiments revealed that the reduced PI turnover in the Ca 2+ -overload muscle was due to both inhibition of the synthesis and stimulation of the breakdown of this lipid that accounted for 30% decrease in the labeled PI from the muscle during 45 min without significant loss of the net PI pool size, suggesting the presence of a relatively smaller compartment of PI pool undergoing a rapid breakdown during Ca 2+ overload. The authors propose that alteration of Ca 2+ homeostasis may modulate the production of putative second messengers, inositol trisphosphate and diacylglycerol, which feed back to regulate [Ca 2+ ]/sub i/ in cardiac muscle

    A study of $D^+\\pi^-$, $D^0 \\pi^+$ and $D^{*+}\\pi^-$ final states is performed using pp collision data, corresponding to an integrated luminosity of 1.0 $fb^{-1}$, collected at a centre-of-mass energy of 7 TeV with the LHCb detector. The $D_1(2420)^0$ resonance is observed in the $D^{*+}\\pi^-$ final state and the $D^*_2(2460)$ resonance is observed in the $D^+\\pi^-$, $D^0 \\pi^+$ and $D^{*+}\\pi^-$ final states. For both resonances, their properties and spin-parity assignments are obtained. In addition, two natural parity and two unnatural parity resonances are observed in the mass region between 2500 and 2800 MeV. Further structures in the region around 3000 MeV are observed in all the $D^{*+}\\pi^-$, $D^+\\pi^-$ and $D^0 \\pi^+$ final states.

    The interference between CP-conserving $\\ks$ and $\\kl \\rightarrow \\threepi$ decay amplitudes was observed by studying the decay rate asymmetries between initial $\\ko$ and $\\kob$ separately for the phase space regions $E_{\\mbox{\\rm \\scriptsize CM}}(\\pi^+)> E_{\\mbox{\\rm \\scriptsize CM}}(\\pi^-)$ and $E_{\\mbox{\\rm \\scriptsize CM}}(\\pi^+)< E_{\\mbox{\\rm \\scriptsize CM}}(\\pi^-)$. For the parameter $\\lambda$ we found $\\mbox{\\rm Re}(\\lambda )=0.036\\pm0.010(\\mbox{\\rm stat.}) ^{+0.002}_{-0.003} (\\mbox{\\rm syst.)}$ and $\\mbox{Im}(\\lambda)$ consistent with zero, leading for the CP-conserving $\\ks \\rightarrow \\threepi$ decay, to a branching ratio $\\mbox{\\rm B} = \\left[4.1 ^{+2.5}_{-1.9 } (\\mbox{\\rm stat.}) ^{+0.5} _{-0.6} (\\mbox{\\rm syst.)}\\right] \\times 10^{-7}$.

  10. Curcumin significantly enhances dual PI3K/Akt and mTOR inhibitor NVP-BEZ235-induced apoptosis in human renal carcinoma Caki cells through down-regulation of p53-dependent Bcl-2 expression and inhibition of Mcl-1 protein stability.

    Full Text Available The PI3K/Akt and mTOR signaling pathways are important for cell survival and growth, and they are highly activated in cancer cells compared with normal cells. Therefore, these signaling pathways are targets for inducing cancer cell death. The dual PI3K/Akt and mTOR inhibitor NVP-BEZ235 completely inhibited both signaling pathways. However, NVP-BEZ235 had no effect on cell death in human renal carcinoma Caki cells. We tested whether combined treatment with natural compounds and NVP-BEZ235 could induce cell death. Among several chemopreventive agents, curcumin, a natural biologically active compound that is extracted from the rhizomes of Curcuma species, markedly induced apoptosis in NVP-BEZ235-treated cells. Co-treatment with curcumin and NVP-BEZ235 led to the down-regulation of Mcl-1 protein expression but not mRNA expression. Ectopic expression of Mcl-1 completely inhibited curcumin plus NVP-NEZ235-induced apoptosis. Furthermore, the down-regulation of Bcl-2 was involved in curcumin plus NVP-BEZ235-induced apoptosis. Curcumin or NVP-BEZ235 alone did not change Bcl-2 mRNA or protein expression, but co-treatment reduced Bcl-2 mRNA and protein expression. Combined treatment with NVP-BEZ235 and curcumin reduced Bcl-2 expression in wild-type p53 HCT116 human colon carcinoma cells but not p53-null HCT116 cells. Moreover, Bcl-2 expression was completely reversed by treatment with pifithrin-α, a p53-specific inhibitor. Ectopic expression of Bcl-2 also inhibited apoptosis in NVP-BE235 plus curcumin-treated cells. In contrast, NVP-BEZ235 combined with curcumin did not have a synergistic effect on normal human skin fibroblasts and normal human mesangial cells. Taken together, combined treatment with NVP-BEZ235 and curcumin induces apoptosis through p53-dependent Bcl-2 mRNA down-regulation at the transcriptional level and Mcl-1 protein down-regulation at the post-transcriptional level.

    A search for the $D^0\\to \\pi^+\\pi^-\\mu^+\\mu^-$ decay, where the muon pair does not originate from a resonance, is performed using proton-proton collision data corresponding to an integrated luminosity of $1.0\\mathrm{fb}^{-1}$ recorded by the LHCb experiment at a centre-of-mass energy of $7\\mathrm{TeV}$. No signal is observed and an upper limit on the relative branching fraction with respect to the resonant decay mode $D^0\\to \\pi^+\\pi^-\\phi(\\to\\mu^+\\mu^-)$, under the assumption of a phase-space model, is found to be \\begin{align} \\mathcal{B}(D^0\\to \\pi^+\\pi^-\\mu^+\\mu^-)/\\mathcal{B}(D^0\\to \\pi^+\\pi^-\\phi(\\to\\mu^+\\mu^-)) < 0.96\\\\ \\end{align} at the $90\\%$ confidence level. The upper limit on the absolute branching fraction is evaluated to be $\\mathcal{B}(D^0\\to \\pi^+\\pi^-\\mu^+\\mu^-) < 5.5 \\, \\times 10^{-7}$ at 90% confidence level. This is the most stringent to date.

    This book contains a compendium of 25 papers published since the 1970s dealing with pi and associated topics of mathematics and computer science. The collection begins with a Foreword by Bruce Berndt. Each contribution is preceded by a brief summary of its content as well as a short key word list indicating how the content relates to others in the collection. The volume includes articles on actual computations of pi, articles on mathematical questions related to pi (e.g., “Is pi normal?”), articles presenting new and often amazing techniques for computing digits of pi (e.g., the “BBP” algorithm for pi, which permits one to compute an arbitrary binary digit of pi without needing to compute any of the digits that came before), papers presenting important fundamental mathematical results relating to pi, and papers presenting new, high-tech techniques for analyzing pi (i.e., new graphical techniques that permit one to visually see if pi and other numbers are “normal”). his volume="" is="" a="" compani...

    Serbia-Montenegro, formerly the Republic of Yugoslavia, is the first European Country where Diabrotica virgifera virgifera Le Conte (Col.: Chrysomelidae) (D.v.v.) was reported in 1992 as an invasive alien pest species, Baca (1993), Camprag and Baca, (1995): From a focal point near Belgrade airport, the maize pest quickly spread in all directions reaching the economic threshold in a number of surrounding countries around 1995. The field experiments described took place in the Banat region east of Belgrade in July of 2002. The plant kairomone mimic 4-methoxycinnamaldehyde (MCA) dissolved in acetone was slowly volatilized from paper squares. It permeated a maize field of known D.v.v. history of 0.5 ha size 3 km north of the village of Crepaja. With release rates of 266 g/ha, max. orientation disruption levels of 55% were achieved. The total amount of MCA was distributed in two manual applications. Readings of orientation levels were continued for eleven days during the latter part of July and into early August of 2002.

    We investigate the applicability of a computational framework, called mutual connectivity analysis (MCA), for directed functional connectivity analysis in both synthetic and resting-state functional MRI data. This framework comprises of first evaluating non-linear cross-predictability between every pair of time series prior to recovering the underlying network structure using community detection algorithms. We obtain the non-linear cross-prediction score between time series using Generalized Radial Basis Functions (GRBF) neural networks. These cross-prediction scores characterize the underlying functionally connected networks within the resting brain, which can be extracted using non-metric clustering approaches, such as the Louvain method. We first test our approach on synthetic models with known directional influence and network structure. Our method is able to capture the directional relationships between time series (with an area under the ROC curve = 0.92 ± 0.037) as well as the underlying network structure (Rand index = 0.87 ± 0.063) with high accuracy. Furthermore, we test this method for network recovery on resting-state fMRI data, where results are compared to the motor cortex network recovered from a motor stimulation sequence, resulting in a strong agreement between the two (Dice coefficient = 0.45). We conclude that our MCA approach is effective in analyzing non-linear directed functional connectivity and in revealing underlying functional network structure in complex systems.

  15. T Cell Intrinsic USP15 Deficiency Promotes Excessive IFN-γ Production and an Immunosuppressive Tumor Microenvironment in MCA-Induced Fibrosarcoma

    Full Text Available USP15 is a deubiquitinase that negatively regulates activation of naive CD4+ T cells and generation of IFN-γ-producing T helper 1 (Th1 cells. USP15 deficiency in mice promotes antitumor T cell responses in a transplantable cancer model; however, it has remained unclear how deregulated T cell activation impacts primary tumor development during the prolonged interplay between tumors and the immune system. Here, we find that the USP15-deficient mice are hypersensitive to methylcholantrene (MCA-induced fibrosarcomas. Excessive IFN-γ production in USP15-deficient mice promotes expression of the immunosuppressive molecule PD-L1 and the chemokine CXCL12, causing accumulation of T-bet+ regulatory T cells and CD11b+Gr-1+ myeloid-derived suppressor cells at tumor site. Mixed bone marrow adoptive transfer studies further reveals a T cell-intrinsic role for USP15 in regulating IFN-γ production and tumor development. These findings suggest that T cell intrinsic USP15 deficiency causes excessive production of IFN-γ, which promotes an immunosuppressive tumor microenvironment during MCA-induced primary tumorigenesis.

  16. Microwave induced stimulation of /sup 32/Pi incorporation into phosphoinositides of rat brain synaptosomes

    Exposure of synaptosomes to microwave radiation at a power density of 10 mW/sq cm or more produced stimulation of the /sup 32/Pi-incorporation into phosphoinositides. The extent of /sup 32/Pi incorporation was found to be much more pronounced in phosphatidylinositol-4-phosphate (PIP), and phosphatidylinositol-4,5-bisphosphate (PIP/sub 2/) as compared to phosphatidylinositol (PI) and phosphatidic acid (PA). Other lipids were also found to incorporate /sup 32/Pi but no significant changes in their labeling were seen after exposure to microwave radiation. Inclusion of 10 mM lithium in the medium reduced the basal labeling of PIP/sub 2/, PIP and PI and increased PA labeling. Li/sup +/ also inhibited the microwave stimulated PIP/sub 2/, PIP and PI labeling but had no effect on PA labeling. Calcium inophore, A/sub 23187/, inhibited the basal and microwave stimulated /sup 32/Pi labeling of PIP and PIP/sub 2/, stimulated basal labeling of PA and PI and had no effect on microwave stimulated PA and PI labeling. Calcium chelator, EGTA, on the other hand, had no effect on basal labeling of PA and PI, stimulated basal PIP and PIP/sub 2/ labeling but did not alter microwave stimulated labeling of these lipids. Exposure of synaptosomes to microwave radiation did not alter the chemical concentration of phosphoinositides indicating that the turnover of these lipids was altered. These results suggest that low frequency microwave radiation alter the metabolism of inositol phospholipids by enhancing their turnover and thus may affect the transmembrane signalling in the nerve endings.

  17. Dimensional analysis beyond the Pi theorem

    Dimensional Analysis and Physical Similarity are well understood subjects, and the general concepts of dynamical similarity are explained in this book. Our exposition is essentially different from those available in the literature, although it follows the general ideas known as Pi Theorem. There are many excellent books that one can refer to; however, dimensional analysis goes beyond Pi theorem, which is also known as Buckingham’s Pi Theorem. Many techniques via self-similar solutions can bound solutions to problems that seem intractable. A time-developing phenomenon is called self-similar if the spatial distributions of its properties at different points in time can be obtained from one another by a similarity transformation, and identifying one of the independent variables as time. However, this is where Dimensional Analysis goes beyond Pi Theorem into self-similarity, which has represented progress for researchers. In recent years there has been a surge of interest in self-similar solutions of the First ...

    The decay $B_c^+ \\rightarrow J/\\psi K^+ K^- \\pi^+$ is observed for the first time, using proton-proton collisions collected with the LHCb detector corresponding to an integrated luminosity of 3 fb$^{-1}$. A signal yield of 78$\\pm$14 decays is reported with a significance of 6.2 standard deviations. The ratio of the branching fraction of $B_c^+ \\rightarrow J/\\psi K^+ K^- \\pi^+$ decays to that of $B_c^+ \\rightarrow J/\\psi \\pi^+$ decays is measured to be $0.53\\pm 0.10\\pm0.05$, where the first uncertainty is statistical and the second is systematic.

    1997-07-01

    We present a study on the invariant mass distribution of {pi}''{+-}{pi}''0 pairs produced in the process {tau}{yields}{pi}''{+-}{pi}''0{nu} . The analysis is based on a sample of 33,096 events collected by the L3 detector between 1991 and 1994. The data is not inconsistent with the hypothesis that the process is being mediated by the p(770) meson alone but is in better agreement with the inclusion of an extra {rho} resonance in the decay of the tau lepton.

    The resonant substructures of $B^0 \\to \\overline{D}^0 \\pi^+\\pi^-$ decays are studied with the Dalitz plot technique. In this study a data sample corresponding to an integrated luminosity of 3.0 fb$^{-1}$ of $pp$ collisions collected by the LHCb detector is used. The branching fraction of the $B^0 \\to \\overline{D}^0 \\pi^+\\pi^-$ decay in the region $m(\\overline{D}^0\\pi^{\\pm})>2.1$ GeV$/c^2$ is measured to be $(8.46 \\pm 0.14 \\pm 0.29 \\pm 0.40) \\times 10^{-4}$, where the first uncertainty is statistical, the second is systematic and the last arises from the normalisation channel $B^0 \\to D^*(2010)^-\\pi^+$. The $\\pi^+\\pi^-$ S-wave components are modelled with the Isobar and K-matrix formalisms. Results of the Dalitz plot analyses using both models are presented. A resonant structure at $m(\\overline{D}^0\\pi^-) \\approx 2.8$ GeV$/c^{2}$ is confirmed and its spin-parity is determined for the first time as $J^P = 3^-$. The branching fraction, mass and width of this structure are determined together with those of the $D...

    Amplitude models are constructed to describe the resonance structure of ${D^{0}\\to K^{-}\\pi^{+}\\pi^{+}\\pi^{-}}$ and ${D^{0} \\to K^{+}\\pi^{-}\\pi^{-}\\pi^{+}}$ decays using $pp$ collision data collected at centre-of-mass energies of 7 and 8 TeV with the LHCb experiment, corresponding to an integrated luminosity of $3.0\\mathrm{fb}^{-1}$. The largest contributions to both decay amplitudes are found to come from axial resonances, with decay modes $D^{0} \\to a_1(1260)^{+} K^{-}$ and $D^{0} \\to K_1(1270/1400)^{+} \\pi^{-}$ being prominent in ${D^{0}\\to K^{-}\\pi^{+}\\pi^{+}\\pi^{-}}$ and $D^{0}\\to K^{+}\\pi^{-}\\pi^{-}\\pi^{+}$, respectively. Precise measurements of the lineshape parameters and couplings of the $a_1(1260)^{+}$, $K_1(1270)^{-}$ and $K(1460)^{-}$ resonances are made, and a quasi model-independent study of the $K(1460)^{-}$ resonance is performed. The coherence factor of the decays is calculated from the amplitude models to be $R_{K3\\pi} = 0.459\\pm 0.010\\,(\\mathrm{stat}) \\pm 0.012\\,(\\mathrm{syst}) \\pm 0.020\\,(...

    A study of the reaction {pi}{sup -} p {yields} p {pi}{sup +}{pi}{sup -}{pi}{sup -} at 2.75 GeV/c was carried out in an 81 cm liquid hydrogen bubble chamber at the CERN proton synchrotron. One observes that the abundant N{sub 33}{sup *++} (1236 MeV) isobar production occurs predominantly backwards in the center of mass of the reaction. This feature suggests a peripheral production mechanism with {pi} exchange. The validity of this hypothesis, which allows the study of the {pi}{sup -}{pi}{sup -} interaction within the frame of the Chew and Low model, is verified. Among other results one finds for the isospin-2 state the values of the elastic {pi}{pi} cross section and of the S and D wave phase shifts.

    In this study we wished to determine whether technetium-99m annexin V, an in vivo marker of cellular injury and death, could be used to noninvasively monitor neuronal injury following focal middle cerebral artery (MCA) occlusion/reperfusion injury. Sixteen adult male Sprague-Dawley rats (along with four controls) underwent left (unilateral) MCA intraluminal beaded thread occlusion for 2 h followed by reperfusion. One hour following tail vein injection of 5-10 mCi of {sup 99m}Tc-annexin V, animals underwent either single-photon emission computerized tomography (SPECT) or autoradiography followed by immunohistochemical analyses. There was abnormal, bilateral, multifocal uptake of {sup 99m}Tc-annexin V in each cerebral hemisphere as seen by both SPECT and autoradiography at 4 h and 1, 3, and 7 days after initiation of occlusion. The average maximal annexin V uptake at 4 h was 310%{+-}85% and 365%{+-}151% above control values (P<0.006) within the right and left hemispheres, respectively, peaking on day 3 with values of 925%{+-}734% and 1,194%{+-}643% (P<0.03) that decreased by day 7 to 489%{+-}233% and 785%{+-}225% (P<0.01). Total lesional volume of the left hemisphere was 226%, 261%, and 451% (P<0.03) larger than the right at 4, 24, and 72 h after injury, respectively. Annexin V localized to the cytoplasm of injured neurons ipsilateral to the site of injury as well as to otherwise normal-appearing neurons of the contralateral hemisphere as confirmed by dual fluorescent microscopy. It is concluded that there is abnormal bilateral, multifocal annexin V uptake, greater on the left than on the right side, within 4 h of unilateral left MCA ischemic injury and that the uptake peaks at 3 days and decreases by 7 days after injury. This pattern suggests that neuronal stress may play a role in the response of the brain to focal injury and be responsible for annexin V uptake outside the region of ischemic insult. (orig.)

    A search for time-integrated CP violation in the Cabibbo-suppressed decay $D^0\\to\\pi^-\\pi^+\\pi^0$ is performed using for the first time an unbinned model-independent technique known as the energy test. Using proton-proton collision data, corresponding to an integrated luminosity of 2.0 fb$^{-1}$ collected by the LHCb detector at a centre-of-mass energy of $\\sqrt{s}$ = 8 TeV, the world's best sensitivity to CP violation in this decay is obtained. The data are found to be consistent with the hypothesis of CP symmetry with a $p$-value of (2.6$\\pm$ 0.5)$\\%$

    The LHCb experiment has recorded the world's largest sample of charmed meson decays. This contribution presents a study of a $D^0$ meson decaying into a final state containing a neutral pion in LHCb. The search for $CP$ violation exploits a novel model-independent unbinned technique to assign a $p$-value for the no $CP$ violation hypothesis. With a data sample size exceeding that of previous measurements by almost an order of magnitude the world's best sensitivity is obtained. The $p$-value of no $CP$ violation hypothesis given data of $D^0\\rightarrow \\pi^-\\pi^+\\pi^0$ decay analysed is found to be $(2.6 \\pm 0.5)\\times 10^{-2}$.

    We present in this thesis the Dalitz Plot analysis of the D{sub s}{sup +} {yields} {pi}{sup +}{pi}{sup -}{pi}{sup +} decay, with the data of the E831/FOCUS, that took data in 1996 and 1997. The masses and widhts of f{sub 0}(980) and f{sub 0}(1370) are free parametres of the fit on Dalitz Plot, objectiving to study in detail these resonances. After this analysis we present the Spectator Model study on the S wave in this decay. For this study we used the formalism developed by M. Svec [2] for scattering. We present the comparison between the Isobar Model, frequently used in Dalitz Plot analysis, and this formalism.

    A search for $CP$ violation using $T$-odd correlations is performed using the four-body $D^0 \\to K^+K^-\\pi^+\\pi^-$ decay, selected from semileptonic $B$ decays. The data sample corresponds to integrated luminosities of $1.0\\,\\text{fb}^{-1}$ and $2.0\\,\\text{fb}^{-1}$ recorded at the centre-of-mass energies of 7 TeV and 8 TeV, respectively. The $CP$-violating asymmetry $a_{CP}^{T\\text{-odd}}$ is measured to be $(0.18\\pm 0.29\\text{(stat)}\\pm 0.04\\text{(syst)})\\%$. Searches for $CP$ violation in different regions of phase space of the four-body decay, and as a function of the $D^0$ decay time, are also presented. No significant deviation from the $CP$ conservation hypothesis is found.

    We study the three-pion decays of the lightest isoscalar vector mesons, {omega} and {phi}, in a dispersive framework that allows for a consistent description of final-state interactions between all three pions. Our results are solely dependent on the phenomenological input for the pion-pion P-wave scattering phase shift. We predict the Dalitz plot distributions for both decays and compare our findings to recent measurements of the {phi}{yields}3{pi} Dalitz plot by the KLOE and CMD-2 collaborations. Dalitz plot parameters for future precision measurements of {omega}{yields}3{pi} are predicted. We also calculate the {pi}{pi} P-wave inelasticity contribution from {omega}{pi} intermediate states.

    Full Text Available Raspberry Pi is a small-sized computer, but it can function like an ordinary computer. Because it can function like a regular PC then it is also possible to run a web server application on the Raspberry Pi. This paper will report results from testing the feasibility and performance of running a web server on the Raspberry Pi. The test was conducted on the current top three most popular web servers, which are: Apache, Nginx, and Lighttpd. The parameters used to evaluate the feasibility and performance of these web servers were: maximum request and reply time. The results from the test showed that it is feasible to run all three web servers on the Raspberry Pi but Nginx gave the best performance followed by Lighttpd and Apache.Keywords: Raspberry Pi, web server, Apache, Lighttpd, Nginx, web server performance

    The selection efficiencies and backgrounds for the decays B+- -> DK+-, where the D denotes a D0bar or D0 which decays into the two-body final states Kpi, KK, pipi, are determined from simulation studies. These are used to estimate the precision with which LHCb will be able to measure the CKM angle gamma. With a data set corresponding to an intergrated luminosity of 2fb-1, a precision of 9.9-11.3 degrees is expected, depending on the strong phase difference between D0 -> K+pi- and D0->K-pi+ decays.

    Recently, blood oxygen level-dependent (BOLD) echo planar imaging (EPI) has been used to estimate blood flow changes. Theoretically, a relative decrement of deoxyhemoglobin in cerebral blood supply induces a MR signal change after neuronal stimulation. In the present study, we have attempted to evaluate CBF reserve capacity by the BOLD EPI in patients who had undergone STA-MCA anastomosis surgery. Then, we compared with the signal intensity changes obtained by this procedure with the CBF changes by Xe-SPECT after acetazolamide administration. Six patients, post-STA-MCA anastomosis surgery, were studied. Pre-operatively, MR signal intensity and CBF, by Xe-SPECT, were increased in the intact side after acetazolamide administration in all patients, and MR signal intensities were decreased in low flow regions after acetazolamide administration in all four patients in whom so-called steal phenomenon was demonstrated by Xe-SPECT study. Post-operatively, poor response was shown after acetazolamide administration with both Xe-SPECT and BOLD EPI in the two patients who had unsuccessful anastomoses. In the successfully anastomosed patients, improved vascular reactivity was demonstrated on BOLD EPI after acetazolamide administration in 3 of 4 patients in whom an improvement of vascular reactivity was demonstrated on Xe-SPECT. In one patient, MRI studies were considered to have technical artifacts, because the MR signal intensity did not increase, even in the intact side after acetazolamide administration. In conclusion, BOLD EPI after acetazolamide administration is an useful procedure for the pre- and post-operative of vascular reserve in patients with ischemic stroke. (author)

    The Ce{sup 3+} doped and undoped samples of alkali earth metal tungstate MWO{sub 4} (M=Ca, Sr, and Ba) phosphors are synthesized by a co-precipitation method in controlled pH environment. The resulting phosphors were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared (FTIR), photoluminescence (PL) and thermoluminescence (TL). XRD pattern and SEM micrographs reveal the formation of agglomerated microcrystalline phosphor. FTIR spectra show the strong absorption around 821 cm{sup −1} due to characteristic vibrations of (WO{sub 4}){sup 2−} complex. PL excitation spectra show broadband in the UV region having peak at 280 nm, and the emission spectrum shows broadband in the visible region with peak in the blue region. The PL emission intensity increases with Ce{sup 3+} concentration with the most effective concentration at 5 mol%. The complex TL glow curve of Ce{sup 3+} doped phosphors is deconvoluted by using a TLAnal computer program. The trap parameters obtained by TLAnal were compared with those calculated by Chen's method and a possible model for TL is discussed. - Highlights: • M{sub 1−x}WO{sub 4}:Ce{sub x} (M=Ca, Sr, and Ba) phosphors are synthesized by the co-precipitation method in controlled pH environment. • Phosphor exhibits broad emission band with maximum in the blue region. • Enhancement of PL emission intensity due to doping of Ce in a host lattice. • The complex TL glow curves were deconvoluted by TLAnal. • FTIR spectra show the main transmittance peaks related to v{sub 3} and v{sub 4} vibration modes of W–O bonds.

    A study of the interaction ..pi../sup -/p ..-->.. n..pi../sup +/..pi../sup -/ is reported where the neutron was produced fast and forward in the laboratory. The data were obtained using an 8 GeV/c ..pi../sup -/ beam that was focused on a liquid hydrogen target located inside the University of Illinois--Argonne National laboratory streamer chamber. The chamber was triggered on the interaction of a fast, forward neutral hadron in thick plate optical spark chambers. A total of 866 events had an acceptable 3-constraint fit to ..pi../sup -/p ..-->.. n..pi../sup +/..pi../sup -/ and satisfied other selection criteria. The data were characterized by backward production of the final states n rho/sup 0/, nf/sup 0/, and ..delta../sup -/(1232)..pi../sup +/. Differential cross sections and decay angular distributions for these resonant states are presented and the implications for the production mechanisms discussed. 20 references.

    The reaction pi /sup -/p to omega n has been studied at 8 and 12 GeV/c incident momenta with the CERN Omega spectrometer using a neutron time of flight trigger. The differential cross sections and the omega - decay density matrix elements are presented as functions of the momentum transfer squared -t in the range of 0.02 to 0.80 GeV/sup 2/. The data are used to evaluate the intercept and slope of both the natural and unnatural parity exchange trajectories. Regge exchange amplitude factorisation tests involving the reaction pi N to omega N are investigated. (32 refs).

    Data on the charge-exchange reaction pi /sup -/p to ( pi /sup +/ pi /sup -/ pi /sup 0/)n have been taken at beam momenta of 12 and 15 GeV /c, using the CERN Omega Multiparticle Spectrometer. A partial-wave analysis has been made of the (3 pi )/sup 0/ system. Both natural and unnatural spin-parity production was observed. The natural parity states can be identified with established resonances. In addition a natural spin-parity enhancement is observed at a mass of about 2 GeV/c /sup 2/ with J/sup P/=4/sup +/ preferred. This effect is called the A /sub 2/*(2030). The unnatural spin-parity production found is consistent with reggeized Deck model predictions. No unambiguous A/sub 1/ or A/sub 3/ production is observed.

    This dissertation presents two analyses performed on data collected with the BABAR detector at the SLAC PEP-II e{sup +}e{sup -} asymmetric-energy B Factory. First, a Dalitz analysis is shown that performs the first measurement of CP violation parameters in the decay B{sup -} {yields} D{sub {pi}{sup +}{pi}{sup -}{pi}{sup 0}}K{sup -} using the decay rate asymmetry and D{sup 0} - {bar D}{sup 0} interference. The results can be used to further constrain the value of the CKM angle {gamma}. The second analysis studies the properties of the X(3872) in neutral and charged B {yields} J/{psi}{pi}{sup +}{pi}{sup -}K decays. Measurements of the branching ratio and mass are presented as well as the search for additional resonances at higher masses.

    We have measured the ratio $\\sigma(e^+e^-\\rightarrow\\pi^+\\pi^-\\gamma)/\\sigma(e^+e^-\\rightarrow \\mu^+\\mu^-\\gamma)$, with the KLOE detector at DA$\\Phi$NE for a total integrated luminosity of $\\sim$ 240 pb$^{-1}$. From this ratio we obtain the cross section $\\sigma(e^+e^-\\rightarrow\\pi^+\\pi^-)$. From the cross section we determine the pion form factor $|F_\\pi|^2$ and the two-pion contribution to the muon anomaly $a_\\mu$ for $0.592pi\\pi}<0.975$ GeV, $\\Delta^{\\pi\\pi} a_\\mu$= $({\\rm 385.1\\pm1.1_{stat}\\pm2.7_{sys+theo}})\\times10^{-10}$.

    Grindlay, Jonathan

    achieve the first full-sky, full-time imaging survey for Gamma-ray Bursts (GRBs) and transients. The full-sky/time coverage immediately increases GRB detections by factors of 6, a significant increase in the search for GRBs from the Early Universe. The proposal will also extend the development of smaller pixel size for the required ASIC chips which will significantly improve angular resolution and make the low-cost Cubesat mission even more compelling. The science goals that a multi-satellite mission enabled by HREXI detectors for high resolution imaging over the full sky include using GRBs to trace star formation back to the very first (Pop III) stars and using flares from quasars to track the growth and evolution of supermassive black holes. Both are key NASA and PCOS science objectives. This is achieved by combining coordinated optical and IR data from a 4piXIO mission with LSST ground-based optical data as well as optical/IR spectra from a future optical-IR spectroscopy telescope in space, such as the proposed TSO probe-class mission.

    In alpha-1 antitrypsin deficiency (AATD), the Z allele is present in 98% of cases with severe disease, and knowledge of the frequency of this allele is essential from a public health perspective. However, there is a remarkable lack of epidemiological data on AATD worldwide, and many of the data currently used are outdated. Therefore, the objective of this study was to update the knowledge of the frequency of the Z allele to achieve accurate estimates of the prevalence and number of Pi*ZZ genotypes worldwide based on studies performed according to the following criteria: 1) samples representative of the general population, 2) AAT phenotyping characterized by adequate methods, and 3) measurements performed using a coefficient of variation calculated from the sample size and 95% confidence intervals. Studies fulfilling these criteria were used to develop maps with an inverse distance weighted (IDW)-interpolation method, providing numerical and graphical information of Pi*Z distribution worldwide. A total of 224 cohorts from 65 countries were included in the study. With the data provided by these cohorts, a total of 253,404 Pi*ZZ were estimated worldwide: 119,594 in Europe, 91,490 in America and Caribbean, 3,824 in Africa, 32,154 in Asia, 4,126 in Australia, and 2,216 in New Zealand. In addition, the IDW-interpolation maps predicted Pi*Z frequencies throughout the world even in some areas that lack real data. In conclusion, the inclusion of new well-designed studies and the exclusion of the low-quality ones have significantly improved the reliability of results, which may be useful to plan strategies for future research and diagnosis and to rationalize the therapeutic resources available.

    2015-05-01

    Full Text Available Exposure to hazardous concentrations of volatile organic compounds indoors in small workshops could affect the health of workers, resulting in respirative diseases, severe intoxication or even cancer. Controlling the concentration of volatile organic compounds is required to prevent harmful conditions for workers in indoor environments. In this document, PI and fuzzy PI controllers were used to reduce hazardous indoor air benzene concentrations in small workplaces. The workshop is represented by means of a well-mixed room model. From the knowledge obtained from the model, PI and fuzzy PI controllers were designed and their performances were compared. Both controllers were able to maintain the benzene concentration within secure levels for the workers. The fuzzy PI controller performed more efficiently than the PI controller. Both approaches could be expanded to control multiple extractor fans in order to reduce the air pollution in a shorter time. The results from the comparative analysis showed that implementing a fuzzy logic PI controller is promising for assuring indoor air quality in this kind of hazardous work environment.

    Idiopathic basal ganglia calcification (IBGC), also called Fahr's disease or recently primary familial brain calcification (PFBC), is characterized by abnormal deposits of minerals including calcium mainly and phosphate in the brain. Mutations in SLC20A2 (IBGC1 (merged with former IBGC2 and IBGC3)), which encodes PiT-2, a phosphate transporter, is the major cause of IBGC. Recently, Slc20a2-KO mice have been showed to have elevated levels of inorganic phosphorus (Pi) in cerebrospinal fluid (CSF); however, CSF Pi levels in patients with IBGC have not been fully examined. We investigated the cases of 29 patients with IBGC including six patients with SLC20A2 mutation and three patients with PDGFB mutation, and 13 controls. The levels of sodium (Na), potassium (K), chloride (Cl), calcium (Ca), and Pi in sera and CSF were determined by potentiometry and colorimetry. Moreover, clinical manifestations were investigated in the IBGC patients with high Pi levels in CSF. The study revealed that the average level of Pi in the CSF of the total group of patients with IBGC is significantly higher than that of the control group, and the levels of Pi in CSF of the IBGC patients with SLC20A2 mutations are significantly higher than those of the IBGC patients with PDGFB mutations, the other IBGC patients and controls. Results of this study suggest that the levels of CSF Pi will be a good biomarker for IBGC1. Copyright © 2018 Elsevier B.V. All rights reserved.

    A new analysis of S-wave production amplitudes for the reaction {pi}{sup -}p{yields}{pi}{sup +}{pi}{sup -}n on a transversely polarized target is performed. It is based on the results obtained by CERN-Cracow-Munich collaboration in the {pi}{pi} energy range from 600 MeV to 1600 MeV at 17.2 GeV/c {pi}{sup -} momentum. Energy-independent separation of the S-wave pseudoscalar amplitude ({pi} exchange) from the pseudovector amplitude (a{sub 1} exchange) is carried out using assumptions much weaker than those in all previous analyses. We show that, especially around 1000 MeV and around 1500 MeV, the a{sub 1} exchange amplitude cannot be neglected. The scalar-isoscalar {pi}{pi} phase shift are calculated using fairly weak assumptions. Our results are consistent both with the so called ``up`` and the well-known ``down`` solution, provided we choose those in which the S-wave phases increase slower with the effective {pi}{pi} mass than the P-wave phases. Above 1420 MeV both sets of phase shifts increase with energy faster than in the experiment on an unpolarized target. This fact can be related to the presence of scalar resonance f{sub o}(1500).

    Growth hormone (GH) is an important factor in the developmental adaptation to enhance P(i) reabsorption; however, the nephron sites and mechanisms by which GH regulates renal P(i) uptake remain unclear and are the focus of the present study. Micropuncture experiments were performed after acute thyroparathyroidectomy in the presence and absence of parathyroid hormone (PTH) in adult (14- to 17-wk old), juvenile (4-wk old), and GH-suppressed juvenile male rats. While the phosphaturic effect of PTH was blunted in the juvenile rat compared with the adult, suppression of GH in the juvenile restored fractional P(i) excretion to adult levels. In the presence or absence of PTH, GH suppression in the juvenile rat caused a significant increase in the fractional P(i) delivery to the late proximal convoluted (PCT) and early distal tubule, so that delivery was not different from that in adults. These data were confirmed by P(i) uptake studies into brush-border membrane (BBM) vesicles. Immunofluorescence studies indicate increased BBM type IIa NaP(i) cotransporter (NaPi-2) expression in the juvenile compared with adult rat, and GH suppression reduced NaPi-2 expression to levels observed in the adult. GH replacement in the [N-acetyl-Tyr(1)-d-Arg(2)]-GRF-(1-29)-NH(2)-treated juveniles restored high NaPi-2 expression and P(i) uptake. Together, these novel results demonstrate that the presence of GH in the juvenile animal is crucial for the early developmental upregulation of BBM NaPi-2 and, most importantly, describe the enhanced P(i) reabsorption along the PCT and proximal straight nephron segments in the juvenile rat.

    In the first part of this experiment, we determined the total cross section for processes yielding only neutral particles, from 300 to 1600 MeV. For this, we counted the number of incident {pi}{sup -}, as defined by a counter telescope, which interact in a liquid-hydrogen target without giving charged particles in a 4{pi} counter surrounding the target. In the second part of this experiment, we have separated the reaction {pi}{sup -} p {yields} {pi}{sup 0} n and {pi}{sup -} p {yields} {pi}{sup 0} {pi}{sup 0} n between 300 and 1100 MeV, by supposing that only these two reactions was realized by placing lead absorbers between the target and 4{pi} counter and by comparing the counting rate for neutral events with and without lead. The transmission thus measured is a function of the average number of photons produced and therefore of the ratio between the two neutral channels, {pi}{sup 0} n and {pi}{sup 0} {pi}{sup 0} n. In the last section of this work, we discuss the experimental results and compare them to those obtained by other authors in the study of photoproduction and the {pi}-nucleon interaction.

    A partial wave analysis of the K/sup 0/ pi /sup +/ pi /sup -/ system produced in the charge exchange reaction K/sup -/p to (K/sup 0/ pi /sup +/ pi /sup -/)n at 4.2 GeV/c has been performed both as a function of K pi pi mass and of t'. The 1/sup +/S wave forms the largest contribution to the K pi pi system and peaks at roughly the same mass as the Q in diffractive K pi pi production. The polarization properties of the 1/sup +/S(K* pi ) and 1/sup +/S(K rho ) waves differ from those of the diffractive 1/sup +/ wave. There is some evidence for a resonance contribution to 1/sup +/S(K* pi ). The strong 2/sup +/ wave is identified with K*(1420) and the K rho /K* pi decay branching ratio determined to be 0.36+or-0.10. An enhancement with spin-parity 1 /sup -/ is observed under the K*(1420). (14 refs).

    The systematic exploration of excited meson and baryon states was the central topic of the COmmon Muon Proton Apparatus for Structure and Spectroscopy (COMPASS) physics program in the years 2008 and 2009 at the CERN facility. Particularly states non fitting a constituent quark model were searched for, identified by their exotic quantum numbers which are forbidden by a simple q anti q scheme. A high energetic hadron-beam on a fixed target yielded in resonances decaying into a large variety of final states. The diffractive and central production mechanisms allowed for a clean exclusive selection of channels such as {pi}{sup -}p {yields} {pi}{sup +}{pi}{sup -}{pi}{sup +}p{sub recoil}, which then were analysed with a high precision and a huge number of events. Apart from the main pion component in the negative hadron beam a small fraction of kaons of about 2.5% allowed the study of light strange resonances in the K{sup -}{pi}{sup +}{pi}{sup -} decay channel. The best measurement in this channel was quoted to be so far the measurement of the WA03 experiment at CERN. The ACCMOR-collaboration has the data recorded and analysed with an experimental set-up very similar to the COMPASS-spectrometer. COMPASS had therefore not only the ability to remeasure this channel with a significantly higher number of events and better precision to cross-check those over 30 years old results. Moreover, improved analysis methods together with new evidences from other experiments, are expected to enlighten our present picture of the hadron spectrum. Chapter 1 introduces the concept of meson spectroscopy. The formation of bound quark anti-quark systems allows to interpret our measurements in terms of coupled quantum numbers, with properties as spin, charge conjugation and parity. Particularly kaonic isospin I=(1)/(2) resonances are classified as proposed by group theory and differences to I=1 and I=0 states, formed mainly by u and d quarks and their anti-quarks, are pointed out.

    The PI3K-AKT signal pathway has been found to be involved in many important physiological and pathological processes of the innate immune system of vertebrates and invertebrates. In this study, the AKT (HdAKT) and PI3K (HdPI3K) gene of small abalone Haliotis diversicolor were cloned and characterized for the important status of PI3K and AKT protein in PI3K-AKT signaling pathway. The full length cDNAs of HdAKT and HdPI3K are 2126 bp and 6052 bp respectively, encoding proteins of 479 amino acids and 1097 amino acids, respectively. The mRNA expression level of fourteen genes in the PI3K-AKT signaling pathway were detected by quantitative real-time PCR. The results showed that all these fourteen genes were ubiquitously expressed in seven selected tissues. Meanwhile, HdAKT was expressed in haemocytes with the highest expression level (p abalone. The mRNA expression of these genes in gills, haemocytes and hepatopancreas was significantly down-regulated after the Vibrio parahaemolyticus stimulation with environment stimulation (thermal, hypoxia and thermal & hypoxia). These results indicate that the dual/multiple stresses defeat the immune system and lead to immunosuppression in abalone. PI3K-AKT signaling pathway may be involved in hypoxia/thermal-induced immunosuppression of small abalone Haliotis diversicolor. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Final states produced by charged baryon exchange in ..pi../sup -/p interactions at 12 GeV/c laboratory momentum have been studied. Forward neutrons with momenta determined by a calorimeter to be greater than 8.5 +- 1.4 GeV/c triggered the SLAC 40-inch hydrogen bubble chamber which operated at a 10 Hz expansion rate. Data on the reactions ..pi../sup -/p..-->..n..pi../sup -/..pi../sup +/, ..pi../sup -/p..-->..n..pi../sup -/..pi../sup +/..pi../sup 0/, and ..pi../sup -/p..-->..n..pi../sup -/..pi../sup -/..pi../sup +/..pi../sup +/are reported. In ..pi../sup -/p..-->..n..pi../sup -/..pi../sup +/ production of rho and f mesons is observed. Differential cross sections are derived and compared with data at lower incident momentum and with theoretical models. In ..pi../sup -/p..-->..n..pi../sup -/..pi../sup +/..pi../sup 0/, ..omega.. production is observed with a differential cross section having a deep dip near u' = 0.2 (GeV/c)/sup 2/. In ..pi../sup -/p..-->..n..pi../sup -/..pi../sup -/..pi../sup +/..pi../sup +/, ..delta../sup -/, rho and f production is observed. The observed mass distributions appear to indicate the production of wide resonances decaying into rho..pi pi... Some evidence for rho-..omega.. interference is also observed.

    A high precision measurement of the ultra-rare K{sup +} {yields} {pi}{sup +} {nu}{bar {nu}} decay at Fermilab would be one of the most incisive probes of quark flavor physics this decade. Its dramatic reach for uncovering new physics is due to several important factors: (1) The branching ratio is sensitive to most new physics models which extend the Standard Model to solve its considerable problems. (2) The Standard Model predictions for the K{sup +} {yields} {pi}{sup +} {nu}{bar {nu}} and K{sub L}{sup 0} {yields} {pi}{sup 0} {nu}{bar {nu}} branching fractions are broadly recognized to be theoretically robust at the 5-10% level. Only a precious few accessible loop-dominated quark processes can be predicted with this level of certainty. (3) The K{sup +} {yields} {pi}{sup +} {nu}{bar {nu}} branching fraction is highly suppressed in the Standard Model to the level < 10{sup -10} (<1 part in 10 billion). This suppression allows physics beyond the Standard Model to contribute dramatically to the branching fraction with enhancements of up to factors of 5 above the Standard Model level. (4) The certainty with which the Standard Model contribution to K{sup +} {yields} {pi}{sup +} {nu}{bar {nu}} can be predicted will permit a 5{sigma} discovery potential for new physics even for enhancements of the branching fraction as small as 35%. This sensitivity is unique in quark flavor physics and allows probing of essentially all models of new physics that couple to quarks within the reach of the LHC. Furthermore, a high precision measurement of K{sup +} {yields} {pi}{sup +} {nu}{bar {nu}} is sensitive to many models of new physics with mass scales well beyond the direct reach of the LHC. The experimental challenge of suppressing backgrounds to enable measurement of K{sup +} {yields} {pi}{sup +} {nu}{bar {nu}} at the 1 in 10-billion Standard Model rate has been met successfully. Several events of K{sup +} {yields} {pi}{sup +} {nu}{bar {nu}} decay have been clearly observed at BNL by

These results are combined with amplitudes measured in B{sup 0} {yields} K{sup 0}{sub s}{pi}{sup +}{pi}{sup -} decays to construct isospin amplitudes from B{sup 0} {yields} K{sup *}{pi} and B{sup 0} {yields} {rho}K decays. We measure the phase of the isospin amplitude {Phi}{sub 3/2}, useful in constraining the CKM unitarity triangle angle {gamma} and evaluate a CP rate asymmetry sum rule sensitive to the presence of new physics operators. We measure direct CP violation in B{sup 0} {yields} K{sup *+}{pi}{sup -} decays at the level of 3 {sigma} when measurements from both B{sup 0} {yields} K{sup +}{pi}{sup -}{pi}{sup 0} and B{sup 0} {yields} K{sup 0}{sub s}{pi}{sup +}{pi}{sup -} decays are combined.

    Theoretical proteome analysis, generated by plotting theoretical isoelectric points (pI) against molecular masses of all proteins encoded by the genome show a multimodal distribution for pI. This multimodal distribution is an effect of allowed combinations of the charged amino acids, and not due to evolutionary causes. The variation in this distribution can be correlated to the organisms ecological niche. Contributions to this variation maybe mapped to individual proteins by studying the variation in pI of orthologs across microorganism genomes. The distribution of ortholog pI values showed trimodal distributions for all prokaryotic genomes analyzed, similar to whole proteome plots. Pairwise analysis of pI variation show that a few COGs are conserved within, but most vary between, the acidic and basic regions of the distribution, while molecular mass is more highly conserved. At the level of functional grouping of orthologs, five groups vary significantly from the population of orthologs, which is attributed to either conservation at the level of sequences or a bias for either positively or negatively charged residues contributing to the function. Individual COGs conserved in both the acidic and basic regions of the trimodal distribution are identified, and orthologs that best represent the variation in levels of the acidic and basic regions are listed. The analysis of pI distribution by using orthologs provides a basis for resolution of theoretical proteome comparison at the level of individual proteins. Orthologs identified that significantly vary between the major acidic and basic regions maybe used as representative of the variation of the entire proteome.

    The series of hybrid inorganic-organic solids T(Im){sub 2}[Ni(CN){sub 4}] with T=Fe, Co, Ni and Im=imidazole were prepared by soft chemical routes from aqueous solutions of the involved building units: imidazole, T{sup 2+} metal and the [Ni(CN){sub 4}]{sup 2-} anionic block. The obtained samples were characterized from infrared and UV-vis spectroscopies, and thermogravimetric, X-ray diffraction and magnetic measurements. Anhydrous solids which crystallize with a monoclinic unit cell, in the I2/a space group with four formula units per cell (Z=4) were obtained. Their crystal structure was solved ab initio from the recorded X-ray powder patterns and then refined by the Rietveld method. The metal T is found with octahedral coordination to four N ends of CN groups and two imidazole molecules while the inner Ni atom preserves its planar coordination. The system of layers remains stacked in an ordered 3D structure through dipole-dipole and {pi}-{pi} interactions between imidazole rings from neighboring layers. In this way, a pillared structure is achieved without requiring the coordination of both nitrogen atoms from imidazole ring. The recorded magnetic data indicate the occurrence of a predominant ferromagnetic interaction at low temperature for Co and Ni but not for Fe. Such magnetic ordering is more favorable for Ni with transition temperature of 14.67 K, which was ascribed to the relatively high polarizing power for this metal. Within the considered T metals, to nickel the highest electron-withdrawing ability corresponds and this leads to an increase for the metal-ligand electron clouds overlapping and to a stronger {pi}-{pi} attractive interaction, two factors that result into a higher magnetic ordering temperature. - Graphical Abstract: Magnetic ordering through the {pi}-{pi} interaction between the imidazole rings.

    We investigated cerebral blood flow (CBF) and metabolism in patients with hemodynamic ischemia by positron emission tomography (PET) and thermal diffusion flow meter. We also studied neuropsychological functions to evaluate the effects of surgical revascularization. Bypass surgery of the superficial temporal artery to the proximal middle cerebral artery was performed on 26 patients satisfying the following categories: stenosis or occlusive lesion in main cerebral arteries; no marked focus of infarction on CT or MRI. PET was performed before and 1 month after the operation, and CBF, the cerebral metabolic rate of oxygen (CMRO 2 ) and oxygen extraction fraction (OEF) were analyzed. Cerebrovascular reserve capacity (CVRC) was also calculated after acetazolamide challenge. CBF during the operation was continuously measured with a thermal diffusion flow meter. CO 2 response of CBF was analyzed before and after anastomosis. Neuropsychological functions were evaluated by Hasegawa dementia scale revised (HDS-R), mini-mental state examination (MMSE) and Wechsler adult intelligence scale revised (WAIS-R). Before the operation, increase in OEF accorded with the decrease in CBF, and a significant relationship between both CBF and CVRC, and OEF and CVRC was found. A decrease in CVRC was noted prior to a decrease in CBF and elevation of OEF. CVRC caused by acetazolamide might reflect CO 2 reactivity. Significant improvement of CBF and CVRC, and normalization of OEF were observed after the operation. Also, significant improvement of neuropsychological function was observed by HDS-R and WAIS-R. Disturbance in neuropsychological function might reflect elevation of OEF. (author)

The title compounds crystallize in a superstructure of the RE{sub 0.67}Pt{sub 2}Al{sub 5} type structure (P6{sub 3}/mmc) in the monoclinic crystal system with space group P12{sub 1}/m1 (Sc{sub 2}Pt{sub 6}Al{sub 15}: a=734.19(2), b=1628.96(10), c=734.19(2) pm, β=119.999(3) ; wR=0.0356, 3034 F{sup 2} values, 68 variables). The superstructure can be derived by the superspace formalism using (3+2)D or (3+1)D interpretations of the diffraction data. The structural relation to the subcell structure is discussed on the basis of a group-subgroup scheme. In the crystal structure strongly bonded [Pt{sub 2}Al{sub 4}]{sup δ-} slabs are alternatingly stacked with ordered layers containing M atoms and Al{sub 3} triangles.

    Full Text Available Este artigo e uma análise da Electra Garrigó de Virgilio Piñera, teatrólogo cubano, e das suas vinculações com o teatro trágico grego, sobretudo com a Electra de Sófocles, acrescida ainda de aproximações com autores modernos que trataram do mesmo tema. Apesar da inspiração grega, Piñera permanece um típico teatrólogo nacional, marcado pelos momentos de grande tensão social da sua época (a tragédia em apreço data de 1941. O conflito produzido pela excessiva autoridade dos pais sobre os filhos, latente neste mito, interessa-o por seu significado dentro da família cubana.

    We investigated cerebral blood flow (CBF) and metabolism in patients with hemodynamic ischemia by positron emission tomography (PET) and thermal diffusion flow meter. We also studied neuropsychological functions to evaluate the effects of surgical revascularization. Bypass surgery of the superficial temporal artery to the proximal middle cerebral artery was performed on 26 patients satisfying the following categories: stenosis or occlusive lesion in main cerebral arteries; no marked focus of infarction on CT or MRI. PET was performed before and 1 month after the operation, and CBF, the cerebral metabolic rate of oxygen (CMRO{sub 2}) and oxygen extraction fraction (OEF) were analyzed. Cerebrovascular reserve capacity (CVRC) was also calculated after acetazolamide challenge. CBF during the operation was continuously measured with a thermal diffusion flow meter. CO{sub 2} response of CBF was analyzed before and after anastomosis. Neuropsychological functions were evaluated by Hasegawa dementia scale revised (HDS-R), mini-mental state examination (MMSE) and Wechsler adult intelligence scale revised (WAIS-R). Before the operation, increase in OEF accorded with the decrease in CBF, and a significant relationship between both CBF and CVRC, and OEF and CVRC was found. A decrease in CVRC was noted prior to a decrease in CBF and elevation of OEF. CVRC caused by acetazolamide might reflect CO{sub 2} reactivity. Significant improvement of CBF and CVRC, and normalization of OEF were observed after the operation. Also, significant improvement of neuropsychological function was observed by HDS-R and WAIS-R. Disturbance in neuropsychological function might reflect elevation of OEF. (author)

    2006-01-01

    This paper presents an extension of the Dpi-calculus due to Hennessy and Riely with constructs for signing and authenticating code and for sandboxing. A sort system, built on Milner's sort systems for the polyadic pi-calculus, is presented and proven sound with respect to an error predicate which...... ensures that errors do not occur outside sandboxes and that authentication and migration only happen when allowed. Futhermore a weak subject reduction result involving partial well sortedness is presented....

    2000-01-01

    Let R be a semiprime Noetherian PI-ring and Q(R) the semisimple Artinian ring of fractions of R. We shall prove the following conditions are equivalent: (1) the Krull dimention of R is at most one, (2) Any ring between R and Q(R) is again right Noetherian, (3) Let a, b be central regular elements of Q(R). Then the subring R + aR[b] of Q(R) is right Noetherian.

  18. Model-Independent Analysis of the Neutron-Proton Final-State Interaction Region in the $\\pi\\pi \\to pn\\pi^+$ Reaction

    Uzikov, Yu N

    2001-01-01

    Experimental data on the \\pi\\pi\\to pn\\pi^+ reaction measured in an exclusive two-arm experiment at 800 MeV show a narrow peak arising from the strong proton-neutron final-state interaction. It was claimed, within the framework of a certain model, that this peak contained up to a 25 % spin-singlet final-state contribution. By comparing the data with those of \\pi\\pi\\to d\\pi^+ in a largely model-independent way, it is here demonstrated that at all the angles measured the whole of the peak could be explained as being due to spin-triplet final states, with the spin-singlet being at most a few percent. Good qualitative agreement with the measured proton analysing power is also found within this approach.

  19. Multimodal Microvascular Imaging Reveals that Selective Inhibition of Class I PI3K Is Sufficient to Induce an Antivascular Response

    Full Text Available The phosphatidylinositol 3-kinase (PI3K pathway is a central mediator of vascular endothelial growth factor (VEGF-driven angiogenesis. The discovery of small molecule inhibitors that selectively target PI3K or PI3K and mammalian target of rapamycin (mTOR provides an opportunity to pharmacologically determine the contribution of these key signaling nodes in VEGF-A-driven tumor angiogenesis in vivo. This study used an array of microvascular imaging techniques to monitor the antivascular effects of selective class I PI3K, mTOR, or dual PI3K/ mTOR inhibitors in colorectal and prostate cancer xenograft models. Micro-computed tomography (micro-CT angiography, dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI, vessel size index (VSI MRI, and DCE ultrasound (DCE-U/S were employed to quantitatively evaluate the vascular (structural and physiological response to these inhibitors. GDC-0980, a dual PI3K/mTOR inhibitor, was found to reduce micro-CT angiography vascular density, while VSI MRI demonstrated a significant reduction in vessel density and an increase in mean vessel size, consistent with a loss of small functional vessels and a substantial antivascular response. DCE-MRI showed that GDC-0980 produces a strong functional response by decreasing the vascular permeability/perfusion-related parameter, Ktrans. Interestingly, comparable antivascular effects were observed for both GDC-980 and GNE-490 (a selective class I PI3K inhibitor. In addition, mTOR-selective inhibitors did not affect vascular density, suggesting that PI3K inhibition is sufficient to generate structural changes, characteristic of a robust antivascular response. This study supports the use of noninvasive microvascular imaging techniques (DCE-MRI, VSI MRI, DCE-U/S as pharmacodynamic assays to quantitatively measure the activity of PI3K and dual PI3K/mTOR inhibitors in vivo.

    The reaction pp -> pf (pi+pi-pi0) ps has been studied at 450 GeV/c in an experiment designed to search for gluonic states. A spin analysis has been performed and the dPT filter applied. The analysis confirms the previous observation that all undisputed qqbar states are suppressed at small dPT. In addition, a clear difference is observed in the production mechanism for the eta and omega.

    We re-evaluate the electromagnetic corrections to {eta}{yields}3{pi} decays at next-to-leading order in the chiral expansion, arguing that effects of order e{sup 2}(m{sub u}-m{sub d}) disregarded so far are not negligible compared to other contributions of order e {sup 2} times a light-quark mass. Despite the appearance of the Coulomb pole in {eta}{yields}{pi}{sup +}{pi}{sup -}{pi}{sup 0} and cusps in {eta}{yields}3{pi}{sup 0}, the overall corrections remain small. (orig.)

    We derive a closed, model independent, expression for the electromagnetic correction factor to a phenomenological hadronic scattering length a/sup h/ extracted from a hydrogenic atom. It is obtained in a non-relativistic approach and in the limit of a short ranged hadronic interaction to terms of order alpha /sup 2/ log alpha using an extended charge distribution. A hadronic pi N scattering length a/sub pi -p//sup h/ = 0.0870(5)m/sub pi //sup -1/ is deduced leading to a pi NN coupling constant from the GMO relation g/sub c //sup 2//(4 pi ) = 14.04(17).

  3. Two PI 3-kinases and one PI 3-phosphatase together establish the cyclic waves of phagosomal PtdIns(3P critical for the degradation of apoptotic cells.

    2012-01-01

    Full Text Available Phosphatidylinositol 3-phosphate (PtdIns(3P is a signaling molecule important for many membrane trafficking events, including phagosome maturation. The level of PtdIns(3P on phagosomes oscillates in two waves during phagosome maturation. However, the physiological significance of such oscillation remains unknown. Currently, the Class III PI 3-kinase (PI3K Vps34 is regarded as the only kinase that produces PtdIns(3P in phagosomal membranes. We report here that, in the nematode C. elegans, the Class II PI3K PIKI-1 plays a novel and crucial role in producing phagosomal PtdIns(3P. PIKI-1 is recruited to extending pseudopods and nascent phagosomes prior to the appearance of PtdIns(3P in a manner dependent on the large GTPase dynamin (DYN-1. PIKI-1 and VPS-34 act in sequence to provide overlapping pools of PtdIns(3P on phagosomes. Inactivating both piki-1 and vps-34 completely abolishes the production of phagosomal PtdIns(3P and disables phagosomes from recruiting multiple essential maturation factors, resulting in a complete arrest of apoptotic-cell degradation. We have further identified MTM-1, a PI 3-phosphatase that antagonizes the activities of PIKI-1 and VPS-34 by down-regulating PtdIns(3P on phagosomes. Remarkably, persistent appearance of phagosomal PtdIns(3P, as a result of inactivating mtm-1, blocks phagosome maturation. Our findings demonstrate that the proper oscillation pattern of PtdIns(3P on phagosomes, programmed by the coordinated activities of two PI3Ks and one PI 3-phosphatase, is critical for phagosome maturation. They further shed light on how the temporally controlled reversible phosphorylation of phosphoinositides regulates the progression of multi-step cellular events.

    2011-01-01

    Full Text Available The “Pi of the Sky” robotic telescope was designed to monitor a significant fraction of the sky with good time resolution and range. The main goal of the “Pi of the Sky” detector is to look for short timescale optical transients arising from various astrophysical phenomena, mainly for the optical counterparts of Gamma Ray Bursts (GRB. The system design, the observation methodology and the algorithms that have been developed make this detector a sophisticated instrument for looking for novae and supernovae stars and for monitoring blasars and AGNs activity. The final detector will consist of two sets of 12 cameras, one camera covering a field of view of 20◦ ×20◦. For data taken with the prototype detector at the Las Campanas Observatory, Chile, photometry uncertainty of 0.018–0.024 magnitudo for stars 7–10m was obtained. With a new calibration algorithm taking into account the spectral type of reference stars, the stability of the photometry algorithm can be significantly improved. Preliminary results from the BGInd variable are presented, showing that uncertainty of the order of 0.013 can be obtained.

    2018-03-17

    To determine the diagnostic accuracy of ADC values in combination with PI-RADS v2 for the diagnosis of clinically significant prostate cancer (CS-PCa) compared to PI-RADS v2 alone. This retrospective study included 155 men whom underwent 3-Tesla prostate MRI and subsequent MR/US fusion biopsies at a single non-academic center from 11/2014 to 3/2016. All scans were performed with a surface coil and included T2, diffusion-weighted, and dynamic contrast-enhanced sequences. Suspicious findings were classified using Prostate Imaging Reporting and Data System (PI-RADS) v2 and targeted using MR/US fusion biopsies. Mixed-effect logistic regression analyses were used to determine the ability of PIRADS v2 alone and combined with ADC values to predict CS-PCa. As ADC categories are more practical in clinical situations than numeric values, an additional model with ADC categories of ≤ 800 and > 800 was performed. A total of 243 suspicious lesions were included, 69 of which were CS-PCa, 34 were Gleason score 3+3 PCa, and 140 were negative. The overall PIRADS v2 score, ADC values, and ADC categories are independent statistically significant predictors of CS-PCa (p values or categories is better discrimination of PI-RADS v2 4 lesions. ADC values and categories help to diagnose CS-PCa when lesions are assigned a PI-RADS v2 score of 4.

    The authors analyze the decay B{sup 0} {yields} K{sub S}{sup 0}{pi}{sup +}{pi}{sup -} using a sample of 232 million {Upsilon}(4S) {yields} B{bar B} decays collected with the BABAR detector at the SLAC PEP-II asymmetric-energy B factory. A maximum likelihood fit finds the following branching fractions: {Beta}(B{sup 0} {yields} K{sup 0}{pi}{sup +}{pi}{sup -}) = (43.0 {+-} 2.3 {+-} 2.3) x 10{sup -6}, {Beta}(B{sup 0} {yields} f{sub 0}({yields} {pi}{sup +}{pi}{sup -})K{sup 0}) = (5.5 {+-} 0.7 {+-} 0.5 {+-} 0.3) x 10{sup -6} and {Beta}(B{sup 0} {yields} K*{sup +}{pi}{sup -}) = (11.0 {+-} 1.5 {+-} 0.5 {+-} 0.5) x 10{sup -6}. For these results, the first uncertainty is statistical, the second is systematic, and the third (if present) is due to the effect of interference from other resonances. They also measure the CP-violating charge asymmetry in the decay B{sup 0} {yields} K*{sup +}{pi}{sup -}, {Alpha}{sub K*{pi}} = -0.11 {+-} 0.14 {+-} 0.05.

    Evans, Tim; John, Malcolm

    This thesis describes two studies of the four-body decays of the neutral charm meson, $D^{0} \\rightarrow K^{-}\\pi^{+}\\pi^{+}\\pi^{-}$ and its doubly Cabibbo-suppressed counterpart $D^{0} \\rightarrow K^{+}\\pi^{-}\\pi^{-}\\pi^{+}$. The first analysis is a model-independent determination of parameters that characterise the phase space averaged interference between the two amplitudes associated with each of these decay modes. The analysis exploits quantum correlations in $D\\bar{D}$ pairs produced from the $\\psi(3770)$ resonance in data collected with the CLEO-c detector. The second half of this thesis describes studies of the resonant structure of these decay modes using proton-proton collision data corresponding to an integrated luminosity of $3.0fb^{-1}$ collected by the LHCb experiment. Studies of the favoured mode, $D^{0} \\rightarrow K^{-}\\pi^{+}\\pi^{+}\\pi^{-}$ , are the most precise studies of the amplitude to date and this data set is one of the largest samples of any decay mode to be studied using an amplitud...

    Highlights: • Role of bulky copolymer on the hole transport properties of polyfluorene thin films has been studied. • Photophysical measurement shows that the introduction of a SY in PFO effectively suppresses pi-stacking/aggregation of conjugated polymers in the solid state. • Current density decreases on blending for a given applied bias. - Abstract: We investigated the effect of blending of a bulky copolymer on the hole transport properties of poly (9,9-dihexyl fluorenyl-2,7-diyl)(PFO) thin films (∼120 nm) at different temperatures by obtaining the current density-voltage measurement. The poly (phenylenevinylene) based copolymer ‘‘Super Yellow” (SY) has been used as a blending component. Such polymer blending matrix is useful as it combines the host polymer (PFO) with the guest polymer of bulky side groups where pi-pi stacking is hindered by bulky side groups. This makes polyflorene much interesting and versatile material for lighting application. It has been found that the current density decreases on blending for a given applied bias. We demonstrated that the current conduction mechanism is bulk limited. It has been analyzed by trapped charge limited currents (TCLC) with electric field. We conclude that the relatively low hole mobility in blends as compared to pristine PFO would result due to increase in the pi-pi stacking distance and disorder.

    The $B^{+}\\to D^{+} K^{+} \\pi^{-}$ decay is observed in a data sample corresponding to $3.0\\,{\\rm fb}^{-1}$ of $pp$ collision data recorded by the LHCb experiment during 2011 and 2012. The signal significance is $8\\,\\sigma$ and the branching fraction is measured to be ${\\cal B}\\left(B^{+}\\to D^{+} K^{+} \\pi^{-}\\right) = (5.31 \\pm 0.90 \\pm 0.48 \\pm 0.35)\\times 10^{-6}$, where the uncertainties are statistical, systematic and due to the normalisation mode $B^{+}\\to D^{-} K^{+} \\pi^{+}$, respectively. The Dalitz plot appears to be dominated by broad structures. Angular distributions are exploited to search for quasi-two-body contributions from $B^{+}\\to D^{*}_{2}(2460)^{0}K^{+}$ and $B^{+}\\to D^{+} K^{*}(892)^{0}$ decays. No significant signals are observed and upper limits are set on their branching fractions.

  12. Molecular symmetry: Why permutation-inversion (PI) groups don't render the point groups obsolete

    Science.gov (United States)

    Groner, Peter

    2018-01-01

    The analysis of spectra of molecules with internal large-amplitude motions (LAMs) requires molecular symmetry (MS) groups that are larger than and significantly different from the more familiar point groups. MS groups are described often by the permutation-inversion (PI) group method. It is shown that point groups still can and should play a significant role together with the PI groups for a class of molecules with internal rotors. In molecules of this class, several simple internal rotors are attached to a rigid molecular frame. The PI groups for this class are semidirect products like H ^ F, where the invariant subgroup H is a direct product of cyclic groups and F is a point group. This result is used to derive meaningful labels for MS groups, and to derive correlation tables between MS groups and point groups. MS groups of this class have many parallels to space groups of crystalline solids.

    2018-05-01

    The Prostate Imaging-Reporting and Data System (PI-RADS) was created in 2012 to establish standardization in prostate multiparametric magnetic resonance imaging (mpMRI) acquisition, interpretation, and reporting. In hopes of improving upon some of the PI-RADS v1 shortcomings, the PI-RADS Steering Committee released PI-RADS v2 in 2015. This paper reviews the accuracy, interobserver agreement, and clinical outcomes of PI-RADS v2 and comments on the limitations of the current literature. Overall, PI-RADS v2 shows improved sensitivity and similar specificity compared to PI-RADS v1. However, concerns exist regarding interobserver agreement and the heterogeneity of the study methodology.

    So-called 0 and {pi} Josephson junctions can be treated as having positive and negative critical currents. This implies that the same phase shift applied to a Josephson junction causes counterflow of supercurrents in 0 and in {pi} junctions connected in parallel provided they are short in comparison with Josephson penetration depth {lambda}{sub J}. We have fabricated several 0, {pi}, 0-{pi}, 0-{pi}-0 and 20 x (0-{pi}-) planar superconductor-insulator-ferromagnet-superconductor Josephson junctions and studied the spatial supercurrent density distribution j{sub s}(x,y) across the junction area using low temperature scanning electron microscopy. At zero magnetic field we clearly see counterflow of the supercurrents in 0 and {pi} regions. The picture also changes consistently in the applied magnetic field.

    In the reaction {pi}{sup -}p {yields}{pi}{sup +}{pi}{sup -}n, we have measured the {pi}{sup +} momentum spectrum at various angles, from which the distributions (d{sup 2}{sigma}/dMd{omega}) of the ({pi}{sup -}n) system have been deduced. These distributions are compared with those obtained by a phenomenological model. This comparison allows a determination of the amplitude of the inelastic waves. It is found that the resonant waves D15 and F15 are no strongly coupled to the channel {delta}(1238) + {pi}. (author) [French] Dans la reaction {pi}{sup -}p {yields} {pi}{sup +}{pi}{sup -}n, nous avons mesure le spectre en impulsion des {pi}{sup +} a differents angles. Les distributions (d{sup 2}{sigma}/dMd{omega}) du systeme ({pi}{sup -}n) en ont ete deduites. Ces distributions sont comparees a celles obtenues par un modele phenomenologique. De la comparaison on determine l'amplitude des ondes inelastiques. Les ondes resonnantes D15 et FIS ne sont pas liees fortement a la voie {delta}(1238) + {pi}. (auteur)

  16. Coincidence measurements of the (. pi. /sup +/,. pi. /sup 0/p) reaction in the /triangle/-resonance region

    This thesis describes an experimental study of the (..pi../sup +/, ..pi../sup 0/p) reaction at incident energy T/sub ..pi../sup +// = 165 MeV. This work is part of the first experiment to detect neutral pions and protons in coincidence in kinematically complete measurements. The reaction was studied on /sup 16/O (using water targets) at several pion angles: theta/sub ..pi../sup 0// = 70/degree/, 80/degree/, 110/degree/, and 130/degree/. At theta/sub ..pi../sup 0// = 110/degree/ measurements were also made on /sup 56/Fe, /sup 120/Sn, and /sup 208/Pb. The neutral pions were detected with the LAMPF ..pi../sup 0/ spectrometer, while the protons were detected in a vertical array of plastic-scintillator ..delta..E-E telescopes, each spanning 8.5 msr. Energy spectra of the differential cross sections d/sup 4/sigma/dE/sub ..pi../sup 0// dE/sub p/d..cap omega../sub ..pi../sup 0//d..cap omega../sub p/ were obtained for each proton telescope and subsequently integrated over proton and pion energy and proton angle. The characteristics of these spectra are consistent with a quasi-free description of the (..pi../sup +/,..pi../sup 0/p) reaction. The angular dependence of dsigma/d..cap omega../sub ..pi../sup 0//(theta/sub ..pi../sup 0//) for /sup 16/O(..pi../sup +/,..pi../sup 0/p) was found to be in accordance with that of the cross section for the corresponding free reaction at backward ..pi../sup 0/ angles. For the /sup 16/O(..pi../sup +/,..pi../sup 0/p) reaction, events in which a p-shell nucleon had been removed were identified. The p-shell events were found to constitute only 40--50% of the total cross section for quasi-free one-nucleon removal. The (..pi../sup +/,..pi../sup 0/p) cross section at theta/sub ..pi../sup 0// = 110/degree/ proved to be almost the same for all target nuclei, possibly slightly decreasing as a function of A. 102 refs., 108 figs., 24 tabs.

    A study of $B_c^+\\to K^+K^-\\pi^+$ decays is performed for the first time using data corresponding to an integrated luminosity of 3.0 $\\mathrm{fb}^{-1}$ collected by the LHCb experiment in $pp$ collisions at centre-of-mass energies of $7$ and $8$ TeV. Evidence for the decay $B_c^+\\to\\chi_{c0}(\\to K^+K^-)\\pi^+$ is reported with a significance of 4.0 standard deviations, resulting in the measurement of $\\frac{\\sigma(B_c^+)}{\\sigma(B^+)}\\times\\mathcal{B}(B_c^+\\to\\chi_{c0}\\pi^+)$ to be $(9.8^{+3.4}_{-3.0}(\\mathrm{stat})\\pm 0.8(\\mathrm{syst}))\\times 10^{-6}$. Here $\\mathcal{B}$ denotes a branching fraction while $\\sigma(B_c^+)$ and $\\sigma(B^+)$ are the production cross-sections for $B_c^+$ and $B^+$ mesons. An indication of $\\overline b c$ weak annihilation is found for the region $m(K^-\\pi^+)<1.834\\mathrm{\\,Ge\\kern -0.1em V\\!/}c^2$, with a significance of 2.4 standard deviations.

    We calculate the s-wave pion-pion scattering length in the isospin I=2 channel in lattice QCD for pion masses ranging from 270 Mev to 485 Mev using two flavors of maximally twisted mass fermions at a lattice spacing of 0.086 fm. Additionally, we check for lattice artifacts with one calculation at a finer lattice spacing of 0.067 fm. We use chiral perturbation theory at next-to-leading order to extrapolate our results. At the physical pion mass, we find m{sub {pi}}a{sup I=2}{sub {pi}}{sub {pi}}=-0.04385(28)(38) for the scattering length, where the first error is statistical and the second is our estimate of several systematic effects.

    The reactions pp -> pf (X0) ps, where X0 is observed decaying to pi0pi0pi0pi0, pi+pi-pi0pi0 and pi+pi-pi+pi-, have been studied at 450 GeV/c. There is evidence for an a2(1320)pi decay mode of the eta2(1645) and eta2(1870) in the pi+pi-pi0pi0 and pi+pi-pi+pi- final states. The f2(1950) is consistent with being a single resonance with a dominant f2(1270)pipi decay mode. The f0(1370) is found to decay dominantly to rho-rho while the f0(1500) is found to decay to rho-rho and sigma-sigma.

  20. Photometric Analysis of Pi of the Sky Data

    Full Text Available Two fully automatic Pi of the Sky detectors with a large field of view, located in Spain (INTA and in Chile (SPDA observe the sky in search of rare optical phenomena, and also collect observations which include many kinds of variable stars. To be able to draw proper conclusions from the data that is received, adequate quality of the detectors is very important. Pi of the Sky data are subject to systematic errors caused by various factors, e.g. cloud cover seen as significant fluctuations in the number of stars observed by the detector, problems with conducting mounting, a strong background of the moon or the passage of a bright object, e.g. a planet, near the observed star. Some of these adverse effects are already detected during cataloging of the individual measurements, but this is not sufficient to make the quality of the data satisfactory for us. In order to improve the quality of our data, we developed two new procedures based on two different approaches. In this paper we will say some words about these procedures, give some examples, and show how these procedures improve the quality of our data.

    3D porous scaffolds are relevant biomaterials to bone engineering as they can be used as templates to tissue reconstruction. The aim of the present study was to produce and characterize in vitro 3D magnesium-carbonate apatite/collagen (MCA/col) scaffolds. They were prepared by using biomimetic approach, followed by cross-linking with 0.25% glutaraldehyde solution (GA) and liofilization. Results obtained with Fourier-transform infrared spectroscopy (FT-IR) confirmed the type-B carbonate substitution, while by X-ray diffraction (XRD), a crystallite size of ∼ 10 nm was obtained. Optical and electron microscopy showed that the cylindrical samples exhibited an open-porous morphology, with apatite nanocrystals precipitated on collagen fibrils. The cross-linked 3D scaffolds showed integrity when immersed in culture medium up to 14 days. Also, the immersion of such samples into an acid buffer solution, to mimic the osteoclastic resorption environment, promotes the release of important ions for bone repair, such as calcium, phosphorus and magnesium. Bone cells (SaOs2) adhered, and proliferated on the 3D composite scaffolds, showing that synthesis and the cross-linking processes did not induce cytotoxicity. Highlights: • 3D scaffolds of Mg-carbonate–apatite and anionic-collagen were produced. • The biomimetic approach and the cross-linking with 0.25% GA solution were employed. • The scaffolds showed open-porous structure and apatite crystals on collagen fibrils. • The cross-linked scaffolds exhibited integrity when immersed in culture medium. • SaOs2 cells adhered and proliferated on the cross-linked scaffolds confirming no cytotoxicity

    The two-pion production pp pp{pi}{sup +}{pi}{sup -} was measured exclusively at T{sub p}=793 MeV using the short version of the COSY-TOF spectrometer. In this measurement both the new EMS-based data acquisition system and a delayed pulse technique have been used, which, in addition to particle identification, energy, time of flight, and angle determination provides pi+ identification for pions in the theta{sub lab} range from 2 to 28 degrees. The measured total cross section for this reaction is {sigma}=4.1(4) {mu}b at T{sub p}=793 MeV. Due to an improved efficiency correction, the earlier measured total cross section has been corrected to {sigma}=1.6 {mu}b at T{sub p}=747 MeV. This value agrees nicely with the results from WASA/PROMICE. The data are compared to previous data and theoretical models which have been developed to understand the results from WASA/PROMICE measurements. The measurements have been carried out with transversally polarized proton beam which made it possible to determine analyzing powers for different subsystems of the two pion production reaction. In contrast to predictions we find significant analyzing power values up to A{sub y}=0.3. The data in the range of Roper excitation confirm that the dominating {pi} {pi} decay channel is N{sup *}{yields}N{sigma}. (orig.)

    Piwi proteins and their associated small RNAs are essential for fertility in animals. In part, this is due to their roles in guarding germ cell genomes against the activity of mobile genetic elements. piRNA populations direct Piwi proteins to silence transposon targets and, as such, form a molecular code that discriminates transposons from endogenous genes. Information ultimately carried by piRNAs is encoded within genomic loci, termed piRNA clusters. These give rise to long, single-stranded, primary transcripts that are processed into piRNAs. Despite the biological importance of this pathway, neither the characteristics that define a locus as a source of piRNAs nor the mechanisms that catalyze primary piRNA biogenesis are well understood. We searched an EMS-mutant collection annotated for fertility phenotypes for genes involved in the piRNA pathway. Twenty-seven homozygous sterile strains showed transposon-silencing defects. One of these, which strongly impacted primary piRNA biogenesis, harbored a causal mutation in CG5508, a member of the Drosophila glycerol-3-phosphate O-acetyltransferase (GPAT) family. These enzymes catalyze the first acylation step on the path to the production of phosphatidic acid (PA). Though this pointed strongly to a function for phospholipid signaling in the piRNA pathway, a mutant form of CG5508, which lacks the GPAT active site, still functions in piRNA biogenesis. We have named this new biogenesis factor Minotaur.

    Piwi proteins and their associated small RNAs are essential for fertility in animals. In part, this is due to their roles in guarding germ cell genomes against the activity of mobile genetic elements. piRNA populations direct Piwi proteins to silence transposon targets and, as such, form a molecular code that discriminates transposons from endogenous genes. Information ultimately carried by piRNAs is encoded within genomic loci, termed piRNA clusters. These give rise to long, single-stranded, primary transcripts that are processed into piRNAs. Despite the biological importance of this pathway, neither the characteristics that define a locus as a source of piRNAs nor the mechanisms that catalyze primary piRNA biogenesis are well understood. We searched an EMS-mutant collection annotated for fertility phenotypes for genes involved in the piRNA pathway. Twenty-seven homozygous sterile strains showed transposon-silencing defects. One of these, which strongly impacted primary piRNA biogenesis, harbored a causal mutation in CG5508, a member of the Drosophila glycerol-3-phosphate O-acetyltransferase (GPAT) family. These enzymes catalyze the first acylation step on the path to the production of phosphatidic acid (PA). Though this pointed strongly to a function for phospholipid signaling in the piRNA pathway, a mutant form of CG5508, which lacks the GPAT active site, still functions in piRNA biogenesis.

    We derive the off-shell nilpotent and absolutely anticommuting Becchi-Rouet-Stora-Tyutin (BRST) as well as anti-BRST transformations s ( a) b corresponding to the Yang-Mills gauge transformations of 3D Jackiw-Pi model by exploiting the "augmented" super-field formalism. We also show that the Curci-Ferrari restriction, which is a hallmark of any non-Abelian 1-form gauge theories, emerges naturally within this formalism and plays an instrumental role in providing the proof of absolute anticommutativity of s ( a) b .

    A spin-parity analysis of a sample of pp to K/sup +/K/sup -/ pi /sup +/ pi /sup -/ pi /sup 0/ annihilation events taken at rest in gaseous H/sub 2/ at NTP is reported. The invariant mass spectrum of the K/sup +/K/sup -/ pi /sup 0/ system shows the presence of the E/t resonance pattern at 1.42 GeV. The analysis of this signal confirms the results obtained by the OBELIX Collaboration in previous works, namely: the existence of two pseudoscalar states at 1.413+or-0.002 and 1.460+or-0.012 GeV with widths 0.051+or-0.004 and 0.120+or-0.015 GeV, respectively. The pp system in the /sup 3/P/sub 1/ wave shows also a signal corresponding to the axial vector f/sub 1/ (1420) decaying to K*K with mass 1.420+or-0.003 GeV and width 0.061+or-0.005 GeV. A study of the incoherent phase space background shows that its origin is mostly due to the reflection of a resonant state in the K/sup +/K /sup -/ pi /sup +/ pi /sup -/ system. The isobar decomposition of this resonant state is mainly f/sub 0/(1370)( pi pi )/sub S/, its parame...

  11. 4Pi microscopy deconvolution with a variable point-spread function.

    Science.gov (United States)

    Baddeley, David; Carl, Christian; Cremer, Christoph

    2006-09-20

    To remove the axial sidelobes from 4Pi images, deconvolution forms an integral part of 4Pi microscopy. As a result of its high axial resolution, the 4Pi point spread function (PSF) is particularly susceptible to imperfect optical conditions within the sample. This is typically observed as a shift in the position of the maxima under the PSF envelope. A significantly varying phase shift renders deconvolution procedures based on a spatially invariant PSF essentially useless. We present a technique for computing the forward transformation in the case of a varying phase at a computational expense of the same order of magnitude as that of the shift invariant case, a method for the estimation of PSF phase from an acquired image, and a deconvolution procedure built on these techniques.

  12. PIWIs Go Viral: Arbovirus-Derived piRNAs in Vector Mosquitoes.

    Directory of Open Access Journals (Sweden)

    Pascal Miesen

    2016-12-01

    Full Text Available Vector mosquitoes are responsible for transmission of the majority of arthropod-borne (arbo- viruses. Virus replication in these vectors needs to be sufficiently high to permit efficient virus transfer to vertebrate hosts. The mosquito immune response therefore is a key determinant for arbovirus transmission. Mosquito antiviral immunity is primarily mediated by the small interfering RNA pathway. Besides this well-established antiviral machinery, the PIWI-interacting RNA (piRNA pathway processes viral RNA into piRNAs. In recent years, significant progress has been made in characterizing the biogenesis and function of these viral piRNAs. In this review, we discuss these developments, identify knowledge gaps, and suggest directions for future research.
