Bo-Qiang Ma CCAST (World Laboratory), P.O. Box 8730, Beijing 100080, China and School of Physics, Peking University, Beijing 100871, China Abstract Koide’s mass relation of charged leptons has been extended to quarks and neutrinos, and we prove here that this relation is independent of energy scale in a huge energy range from 1 GeV to 2 × 1016 GeV. By using the parameters ku, kd and kν to descr...
for the Rydberg constant, the value of the Rydberg constant being cR0 = 3.2899 X 1016 cm.; and (c) Einstein's quantum equation. The experimental values of e and of h are not used in this calculation of mo, nor are the results of any other experiments than ours on the reflection of x-rays by calcite, and the experimental determinations of the fundamental constants d and cR,. From our value of mo...
We have reviewed prospective data on 1016 patients who underwent unilateral total hip replacement to establish the pre-operative risk factors associated with peri-operative blood transfusion. Most patients who required transfusion were older and were of lower weight, height, pre-operative haemoglobin level and body mass index than patients who were not transfused. Multivariate analysis revealed...
A new characteristic waveform (CW) interpolation coder is proposed in this paper. In the proposed coder, two characteristic waveforms are extracted from LPC residual signal at each frame. The Waveform Interpolation (WI) is operated within the frame. In the novel WI, variable dimension vector quantization (VDVQ) and power vector quantization are proposed and the low frequency band (LFB) and high...
Type I string theory in the presence of internal magnetic fields provides a concrete realization of split supersymmetry. To lowest order, gauginos are massless while squarks and sleptons are superheavy. For weak magnetic fields, the correct Standard Model spectrum guarantees gauge coupling unification with sin2 θW = 3/8 at the compactification scale of MGUT ≃ 2× 1016 GeV. I discuss mechanisms f...

1550-7998=20 We implement inflation within a realistic supersymmetric SO 10 model in which the doublet-triplet splitting is realized through the Dimopoulos-Wilczek mechanism, the MSSM problem is resolved, and Higgsino mediated dimension five nucleon decay is heavily suppressed. The cosmologically unwanted topological defects are inflated away, and from T=T, the B L breaking scale is estimated t...
Short Distance Physics and Initial State Effects on the CMB Power Spectrum and Cosmological Constant
We investigate a modification in the action of inflaton due to noncommutativity leads to a nonstandard initial vacuum and oscillatory corrections in the initial power spectrum. We show that the presence of these oscillations causes a drop in the WMAP χ2 about ∆χ2 ∼ 8.5. We also show that this nonstandard initial vacuum state can provide a rolling in cosmological constant. As a bonus, from the p...
موضوع این مقاله سنجش میزان احساس تعلق به جامعه ایران و عوامل مؤثر بر آن است. تعلق اجتماعی در دو بعد تعلق عاطفی و تعلق عملی تعریف و با بهرهگیری از روش پیمایش و استفاده از پرسشنامه محققساخته در طیف لیکرت و تکنیک نمونهگیری خوشهای از مناطق 22 گانه تهران، 1016 پرسشنامه صحیح از ساکنین ۱۸ تا 65 سال بهدست آمد. یافتهها نشان داد که تعلق به جامعه ایران در سطح متوسط قرار دارد و متغیرهای تعلق دینی، ...
Hospitalized patients have a potential risk for nosocomial infections. Airborne fungi are one of the main causes of fungal infections in this group. The objective of this study was to investigate the concentrations and species of airborne fungi in two general hospitals in Shiraz, southern Iran. Air samples were collected from high-risk wards, using settle plate method. Fungal colonies were iden...
