Abstract

International audience; We describe an analysis comparing the pp¯ elastic cross section as measured by the D0 Collaboration at a center-of-mass energy of 1.96 TeV to that in pp collisions as measured by the TOTEM Collaboration at 2.76, 7, 8, and 13 TeV using a model-independent approach. The TOTEM cross sections, extrapolated to a center-of-mass energy of s=1.96 TeV, are compared with the D0 measurement in the region of the diffractive minimum and the second maximum of the pp cross section. The two data sets disagree at the 3.4σ level and thus provide evidence for the t-channel exchange of a colorless, C-odd gluonic compound, also known as the odderon. We combine these results with a TOTEM analysis of the same C-odd exchange based on the total cross section and the ratio of the real to imaginary parts of the forward elastic strong interaction scattering amplitude in pp scattering for which the significance is between 3.4σ and 4.6σ. The combined significance is larger than 5σ and is interpreted as the first observation of the exchange of a colorless, C-odd gluonic compound.

Abstract

Using suppression subtractive hybridization technique, we found that 2 novel genes (AEUG1 and AEUG3) were highly expressed in the adipocytes compared with preadipocytes. We then identified that these 2 genes were both angiotensin-converting enzyme 2 (ACE2). We applied 3'RACE (rapid amplification of cDNA end), 5'RACE, and PCR to obtain the full-length porcine ACE2 cDNA sequence. Because eicosanoids derived from PUFA are involved in regulating blood pressure, we hypothesized that PUFA can regulate the expression of the vasodilator ACE2. Preadipocytes from Landrace pigs were induced to differentiate for 4 d, then treated with 50 [micro]M of different PUFA, CLA, arachidonic acid, eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), or stearic acid (18:0). Addition of EPA or 18:0 for 48 h did not change the ACE2 mRNA abundance, whereas the treatments of arachidonic acid, CLA, and DHA significantly decreased ACE2 mRNA abundance after 48 h (P [less than or equal to] 0.05). Treatment with PUFA did not change (P > 0.05) type I and type II angiotensin receptor mRNA abundance. To further understand how PUFA metabolites affect ACE2 mRNA expression, we inhibited individual enzymes that are involved in eicosanoid production. We found that 3 individual eicosanoid pathway enzyme inhibitors recovered the PUFA effect on the expression of ACE2, indicating these pathways are involved in mediating the PUFA function. In conclusion, we obtained the full-length porcine ACE2 cDNA sequence and found PUFA could downregulate the expression of ACE2 through its metabolites without changing the expression of their receptor in porcine adipocytes.

Abstract

A total of 50 weaning pigs (16 d of age; 4.72 [+ or -] 0.23 kg of BW) were selected to investigate the effect of dietary chito-oligosaccharide (COS) supplementation on growth performance, fecal shedding of Escherichia coli and Lactobacillus, apparent digestibility, and small intestinal morphology. Pigs housed in individual metabolic cages were assigned randomly to 5 treatments (n = 10), including 1 basal diet (control), 3 diets with COS supplementation (100, 200, and 400 mg/kg), and I diet with chlortetracycline (CTC) supplementation (80 mg/kg). Fresh fecal samples were collected to evaluate shedding of E. coli and Lactobacillus on d 0, 7, 14, and 21 postweaning. Fresh fecal samples collected from each cage from d 19 to 21 were stored frozen for determination of apparent total tract digestibility. On d 21, all pigs were killed to collect the middle sections of the duodenum, jejunum, and ileum for determination of mucosa morphology. Supplementation of COS at 100 and 200 mg/kg and supplementation of CTC improved (P < 0.05) overall ADG, ADFI, and G:F in comparison with the control. Supplementation of COS at 200 mg/kg as well as supplementation of CTC increased (P < 0.05) apparent total tract digestibility of DM, GE, CP, crude fat, Ca, and P, whereas COS at 100 mg/kg increased (P < 0.05) the digestibility of DM, Ca, and P in comparison with the control diet. Pigs receiving diets supplemented with COS or CTC had a decreased (P < 0.05) incidence of diarrhea and decreased diarrhea scores compared with control pigs. Fecal samples from pigs receiving diets supplemented with COS had greater (P < 0.05) Lactobacillus counts than those from control pigs and pigs receiving diets supplement-ed with CTC on d 14 and 21. However, supplementation of COS at 200 mg/kg and supplementation of CTC decreased (P < 0.05) E. coli counts in the feces on d 21 compared with the control diet. Dietary supplementation of COS at 200 mg/kg and of CTC increased (P < 0.05) the villus height and villus:crypt ratio at the ileum and jejunum, and COS at 100 mg/kg also increased (P < 0.05) the villus height in the ileum compared with the control diet. The current results indicated that dietary supplementation of COS at 100 and 200 mg/kg enhanced growth performance by increasing apparent digestibility, decreasing the incidence of diarrhea, and improving small intestinal morphology.

Abstract

The response of CsI(T1) crystals to nuclear recoils and [gamma]s down to 3 keV has been studied, and it has been demonstrated that the pulse shape discrimination capability for CsI(T1) is better than that for NaI(T1). Extensive study of internal background of CsI powder was performed and a lot of efforts have been made to reduce the internal background sources such as [sup.137]Cs and [sup.87]Rb. The [sup.137]Cs concentration of 2 mBq/kg was achieved successfully in the CsI powder using ultra-pure water for whole extraction process. The Rb concentration was successfully reduced to be less than 1 ppb by the recrystallization method. The CsI(T1) crystal used for the experiment was grown with the ultra-low background CsI powder and a dimension of the CsI(T1) crystal is 8 x 8 x 30 [cm.sup.3] which corresponds to weight of 8.7 kg. The number of photoelectrons is measured to be about 4-6/keV with a RbCs photocathode PMT. The background of CsI(T1) crystals were measured in the shielding of 30 cm thick mineral oil, 15 cm thick lead, 5 cm thick polyethylene and 10 cm copper at the 700 m minimum depth of underground laboratory at YangYang Pumped Storage Power Plant in Korea. The WIMP search with low background CsI(T1) crystals has been carried out by the Korean Invisible Mass Search (KIMS) Collaboration and the lower limit on WIMP-nucleon cross section are reported.

Abstract

COSINE-100 is a direct detection dark matter search experiment that uses a 106 kg array of eight NaI(Tl) crystals that are kept underground at the Yangyang Underground Laboratory to avoid cosmogenic activation of radioisotopes by cosmic rays. Even though the cosmogenic activity is declining with time, there are still significant background rates from the remnant nuclides. In this paper, we report measurements of cosmogenic isotope contaminations with less than one year half-lives that are based on extrapolations of the time dependent activities of their characteristic energy peaks to activity rates at the time the crystals were deployed underground. For longer-lived 109Cd ( T 1 / 2 = 1.27 y) and 22Na ( T 1 / 2 = 2.6 y), we investigate time correlations and coincidence events due to several emissions. The inferred sea-level production rates are compared with calculations based on the ACTIVIA and MENDL-2 model calculations and experimental data. The results from different approaches are in reasonable agreement with each other. For 3H, which has a long, 12.3 year half-life, we evaluated the activity levels and the exposure times that are in reasonable agreement with the time period estimated for each crystal’s exposure.

Abstract

We describe an analysis comparing the $p\bar{p}$ elastic cross section as measured by the D0 Collaboration at a center-of-mass energy of 1.96 TeV to that in $pp$ collisions as measured by the TOTEM Collaboration at 2.76, 7, 8, and 13 TeV using a model-independent approach. The TOTEM cross sections extrapolated to a center-of-mass energy of $\sqrt{s} =$ 1.96 TeV are compared with the D0 measurement in the region of the diffractive minimum and the second maximum of the $pp$ cross section. The two data sets disagree at the 3.4$\sigma$ level and thus provide evidence for the $t$-channel exchange of a colorless, $C$-odd gluonic compound, also known as the odderon. We combine these results with a TOTEM analysis of the same $C$-odd exchange based on the total cross section and the ratio of the real to imaginary parts of the forward elastic scattering amplitude in $pp$ scattering. The combined significance of these results is larger than 5$\sigma$ and is interpreted as the first observation of the exchange of a colorless, $C$-odd gluonic compound., Comment: D0 and TOTEM Collaborations

Abstract

The effects of clay on the morphology of the poly(acrylonitrile-butadiene-styrene) (ABS)/polypropylene (PP) nanocomposites were investigated. From the studies of wide angle X-ray diffraction (WAXD) and transmission electron microscopy (TEM) analysis of the ABS/PP (70/30) nanocomposites with clay, it was observed that most of the clay existed in the ABS matrix because of the good affinity between the ABS and clay which contained benzyl group. From the studies of the scanning electron microscopy (SEM) analysis, the size of the PP droplet decreased with clay from 16.7 to 5.6 µm when the clay was added up to 4.0 phr. When the clay content was increased, the droplet of the dispersed phase (PP) was shown to elongated structure. The elongated structure could be explained by the decrease of the viscosity ratio of the PP and continuous phase (ABS) with clay, which corresponded to the increase of the viscosity of the continuous phase (ABS/clay). From the results of the SEM, TEM, and WAXD analysis, it is suggested that the increase of the viscosity of the continuous phase (ABS/clay) is mainly due to the location of clay in the ABS matrix. POLYM. ENG. SCI., 47:1671-1677, 2007. © 2007 Society of Plastics Engineers, INTRODUCTION Since the report of the Toyota motors [1-3], the polymer/clay nanocomposites have been extensively studied because of its superior properties [1-20]. For example, the heat distortion temperature of the [...]

Abstract

Scintillation properties of calcium molybdate are investigated. The emission spectrum is broad with a maximum at 520 nm. At room temperature the light yield is 4% of CsI(TI) (400 photoelectrons/MeV) and the decay time is 17 [micro]s. During cooling the light yield and decay time increase. Prospects of optimization of this scintillator are also discussed. The feasibility of the material for the search of neutrinoless double beta decay of [sup.100]Mo is analyzed. A half life limit of [T.sub.1/2] = 1 * [10.sup.25] years (68% CL) seems feasible with CaMo[O.sub.4] scintillator, running with 10 kg of [sup.100]Mo for 5 years. The background due to two neutrino double beta decay of [sup.48]Ca is also considered. Requirements for new scintillators for double beta decay search are formulated. Index Terms--Crystal growth, low background, molybdenum compounds, neutrinos, scintillation detectors.

Abstract

Simulation and experimental studies have been carried out on the transient gas-liquid interface development and gas penetration behavior during the cavity filling and gas packing stage in the gas-assisted injection molding of a spiral tube cavity. The evolution of the gas/melt interface and the distribution of the residual wall thickness of skin melt along with the advancement of gas/melt front were investigated. Numerical simulations were implemented on a fixed mesh covering the entire cavity. The residual thickness of a polymer layer and the length of gas penetration in the moldings were calculated using both the simulation and model developed in Part I of this study and commercial software (C-Mold). Extensive molding experiments were performed on polystyrene at different processing conditions. The obtained results on the gas bubble dynamics and penetration behaviors were compared with those predicted by the present simulation and C-Mold, indicating the good predictive capability of the proposed model. Polym. Eng. Sci. 44:992-1002, 2004., INTRODUCTION During the past three decades, novel technologies have been introduced to produce parts with special design features that cannot be accomplished by conventional injection molding methods.

Abstract

This paper presents a method to investigate the characteristics of hydrodynamic bearings of a HDD spindle motor considering the variation of the clearance as well as the lubricant viscosity due to elevated temperature. Iterative finite element analysis of heat conduction and thermal deformation is performed to determine the viscosity and clearance of hydrodynamic bearings at elevated temperature until the temperature in the bearing area converges. The proposed method is verified by comparing the calculated temperature with the measured one at elevated surrounding temperature as well as in room temperature. This research shows that elevated temperature changes the clearance as well as the lubricant viscosity of the hydrodynamic bearings of a HDD spindle motor. Once the viscosity and clearance of hydrodynamic bearings of a HDD spindle motor are determined, finite element analysis of the Reynolds equation is performed to investigate the static and dynamic characteristics of hydrodynamic bearings of a HDD spindle motor at elevated temperature. It also shows that the variation of clearance due to elevated temperature is another important design consideration which affects the static and dynamic characteristics of the hydrodynamic bearings of a HDD spindle motor.
