KATRIN Sensitivity to Sterile Neutrino Mass in the Shadow of Lightest Neutrino Mass

The presence of light sterile neutrinos would strongly modify the energy spectrum of the Tritium \beta-electrons. We perform an analysis of the KATRIN experiment's sensitivity by scanning almost all the allowed region of neutrino mass-squared difference and mixing angles of the 3+1 scenario. We consider the effect of the unknown absolute mass scale of active neutrinos on the sensitivity of KATRIN to the sterile neutrino mass. We show that after 3 years of data-taking, the KATRIN experiment can be sensitive to mixing angles as small as sin^2 (2\theta_s) ~ 10^-2. Particularly we show that for small mixing angles, sin^2 (2\theta_s) < 0.1, the KATRIN experiment can gives the strongest limit on active-sterile mass-squared difference.Comment: 4 pages, 2 figures, matches the published versio

Conception Rates and Sex Concomitant of Bali Calves Following Oestrus Synchronization and Artificial Insemination of Frozen- Sexed Semen Under Farm Conditions

The objective of this study was to determine the conception rate of Bali cattle synchronized andartificially inseminated with frozen thawed sexed-semen concomitant with its calves sex. Thisexperiment was conducted in two cattle farms in West Lombok Regency. Oestrus was synchronized witha single injection i.m. of 5 cc Lutalyse ® containing 25 mg of PGF 2α (Lutalyse, Sterile Solution,Pharmacia Animal Health). The observation was conducted in the responded cattle that artificiallyinseminated at once oestrus. Pregnancy diagnosis was conducted by rectal palpation at about day-90. InFarm 1, the conception rate (CR) of PGF 2α -treated and non-treated animals were 29/63 (46.03%) and71/75 (94.66%), respectively. However, in Farm 2 the corresponding values were 38/89 (42.70%) and10/23 (43.48%), respectively. CR in both farms were found being 100%. Sex concomitant rate forfemale calves born in Farm 1 was found being 94/100 (94.00%), whilst in Farm 2, sex concomitant ratefor male calves born was recorded to be 45/48 (93.75%). It was concluded that under farm conditionsoestrus synchronization using PGF 2α in conjunction with AI of frozen-thawed Bali sexed spermatozoamight be used with acceptable conception and calving rates that above 90 % concomitant with itsrespective calve-sex rates

Synthesis of single-component metallic glasses by thermal spray of nanodroplets on amorphous substrates

We show that single component metallic glasses can be synthesized by thermal spray coating of nanodroplets onto an amorphous substrate. We demonstrate this using molecular dynamics simulations of nanodroplets up to 30 nm that the spreading of the nanodroplets during impact on a substrate leads to sufficiently rapid cooling (10^(12)–10^(13) K/s) sustained by the large temperature gradients between the thinned nanodroplets and the bulk substrate. However, even under these conditions, in order to ensure that the glass transition outruns crystal nucleation, it is essential that the substrate be amorphous (eliminating sites for heterogeneous nucleation of crystallization)

Aplikasi Ajaran Islam dalam Komunitas Adat Amma Towa di Desa Tana Towa, Kecamatan Kajang, Kabupaten Bulukumba

Hasil penelitian menunjukkan bahwa aplikasi ajaran Islam dengan melihat pemahaman komunitas adat Amma Towa pada aspek syariat tidak menjadi prioritas atau hal yang diutamakan dalam kehidupannya. Walaupun demikian mereka dalam realitasnya mengetahui aspek-aspek dari rukun Islam. Dari upaya tersebut mereka membangun konsepsi dengan cara tersendiri. Seperti syahadat yang dimaknai hanya penjagaan melalui hati, pelaksanaan salat dengan konsepsi sumbajang tangattappu je’ne talluka, rangkaian pemahamannya tidak dengan gerakan, namun pada kemampuan hati dan moral. Selanjutnya pelaksanaan puasa pada bulan Ramadan yang hanya dilakukan tiga kali dalam satu bulan, yaitu awal Ramadan, pertengahan serta akhir Ramadan. Hal tersebut pula menunjukkan pola dialog komunitas adat Amma Towa yaitu dengan upayanya menafsirkan, membaca ulang, membangun defenisi serta membuat makna keislamannya. Sehingga menjadi corak Islam yang khas. Pada ibadah yang terakhir yaitu ibadah haji juga tak luput dari rekontekstualisasi dari komunitas adat Amma Towa. Berhaji dalam kebudayaan Amma Towa di samakan dengan akkattere yakni tradisi memotong rambut. Kesucian yang digambarkan dalam berhaji menurut komunitas adat Amma Towa di anggap sama, fungsi ataupun tujuannya. Adapun pada aspek zakat, hanya mengikuti dari keputusan pemerintah Desa dan tidak ada kaitannya dengan adat

Dynamic response of phenolic resin and its carbon-nanotube composites to shock wave loading

We investigate with nonreactive molecular dynamics simulations the dynamic response of phenolic resin and its carbon-nanotube (CNT) composites to shock wave compression. For phenolic resin, our simulations yield shock states in agreement with experiments on similar polymers except the “phase change” observed in experiments, indicating that such phase change is chemical in nature. The elastic–plastic transition is characterized by shear stress relaxation and atomic-level slip, and phenolic resin shows strong strain hardening. Shock loading of the CNT-resin composites is applied parallel or perpendicular to the CNT axis, and the composites demonstrate anisotropy in wave propagation, yield and CNT deformation. The CNTs induce stress concentrations in the composites and may increase the yield strength. Our simulations suggest that the bulk shock response of the composites depends on the volume fraction, length ratio, impact cross-section, and geometry of the CNT components; the short CNTs in current simulations have insignificant effect on the bulk response of resin polymer

Estimation of Primordial Spectrum with post-WMAP 3 year data

In this paper we implement an improved (error sensitive) Richardson-Lucy deconvolution algorithm on the measured angular power spectrum from the WMAP 3 year data to determine the primordial power spectrum assuming different points in the cosmological parameter space for a flat LCDM cosmological model. We also present the preliminary results of the cosmological parameter estimation by assuming a free form of the primordial spectrum, for a reasonably large volume of the parameter space. The recovered spectrum for a considerably large number of the points in the cosmological parameter space has a likelihood far better than a `best fit' power law spectrum up to \Delta \chi^2_{eff} \approx -30. We use Discrete Wavelet Transform (DWT) for smoothing the raw recovered spectrum from the binned data. The results obtained here reconfirm and sharpen the conclusion drawn from our previous analysis of the WMAP 1st year data. A sharp cut off around the horizon scale and a bump after the horizon scale seem to be a common feature for all of these reconstructed primordial spectra. We have shown that although the WMAP 3 year data prefers a lower value of matter density for a power law form of the primordial spectrum, for a free form of the spectrum, we can get a very good likelihood to the data for higher values of matter density. We have also shown that even a flat CDM model, allowing a free form of the primordial spectrum, can give a very high likelihood fit to the data. Theoretical interpretation of the results is open to the cosmology community. However, this work provides strong evidence that the data retains discriminatory power in the cosmological parameter space even when there is full freedom in choosing the primordial spectrum.Comment: 13 pages, 4 figures, uses Revtex4, new analysis and results, references added, matches version accepted to Phys.

Does the Type of Skin Marker Prevent Marking Erasure of Surgical-Site Markings?

Objective: Site marking is essential to prevent wrong-site surgery, and there are many skin markers commercially available. However, preoperative skin preparation can erase the site mark, especially when a chlorhexidine skin preparation solution that requires skin scrubbing is used. The purpose of our study was to test the hypothesis that some markers can withstand skin preparation with a chlorhexidine-based skin preparation solution in a manner similar to that of an iodine-based solution. Methods: On each of 5 cadaveric skin flaps, we made 2 rows of site markings with 9 types of markers. We then subjected one row of markings on each flap to a chlorhexidine-based solution and the other row to an iodine-based solution. A digital photograph was taken before and after each skin preparation. Using imaging software, the contrast in grayscale between the skin and skin marking was measured on each photograph. The effect of the type of marker and skin preparation solution on the difference in grayscale contrast was evaluated by multiple linear regression analysis and significant differences were determined (P < .05). Results: In all cases, the chlorhexidine-based skin preparation solution significantly decreased the contrast measured. No marker was significantly better than another. Conclusions: We conclude that all 9 skin markers are significantly erased with the chlorhexidine-based skin preparation solution. The development of a better skin marker or a chlorhexidine-based skin preparation solution that does not erase site markings is essential to prevent wrong-site surgeries and promote patient safety
