background: about 10% of infertilities with obstructive azoospermia are congenital and caused by cf gene mutations. m469i mutation was observed for the first time in taiwanese patients. this mutation not only causes cf, but also may be the origin of infertility too. objective: in this study, we aimed in designing a rapid, reliable rflp-pcr procedure for detection of m469i mutation. the correlat...
Among the Active Galactic Nuclei (AGN) that have suffered type mutations, the classically classified Seyfert 2 NGC 7582 recently found at a Seyfert 1 stage, is perhaps one of the most puzzling cases, since it defies a well supported case for unification. We investigate the possibility that this type transition, common to other 12 AGN, is driven by supernovae (SN) exploding in a nuclear/circumnu...
By using a molecular beam epitaxy technique, we fabricate a new type of superconducting superlattices with controlled atomic layer thicknesses of alternating blocks between the heavy-fermion superconductor CeCoIn5, which exhibits a strong Pauli pair-breaking effect, and nonmagnetic metal YbCoIn5. The introduction of the thickness modulation of YbCoIn5 block layers breaks the inversion symmetry ...
Numerical inversions for earthquake source parameters from tsunami wave data usually incorporate subjective elements to stabilize the search. In addition, noisy and possibly insufficient data result in instability and non-uniqueness in most deterministic inversions, which are barely acknowledged. Here, we employ the satellite altimetry data for the 2004 Sumatra-Andaman tsunami event to invert t...
The recent discovery of a Weyl semimetal in TaAs offers the first Weyl fermion observed in nature and dramatically broadens the classification of topological phases. However, in TaAs it has proven challenging to study the rich transport phenomena arising from emergent Weyl fermions. The series MoxW1-xTe2 are inversion-breaking, layered, tunable semimetals already under study as a promising plat...
Park, Sang-Hee. 2009. Resolving Multiple fdo.fragments in English: A Syntax-Pragmatics Approach. SNU Working Papers in English Lingnistics and Langnage 8, 16-27. This study attempts to provide a new analysis of multiple wh·fragments, the so-called 'multiple sluicing', in English. Against previous approaches which resort to a reconslruction-based resolution or gapping, the proposed analysis capt...
Consider the following stochastic model for immune response. Each pathogen gives birth to a new pathogen at rate λ. When a new pathogen is born, it has the same type as its parent with probability 1− r. With probability r, a mutation occurs, and the new pathogen has a different type from all previously observed pathogens. When a new type appears in the population, it survives for an exponential...

background: apolipoprotein a2 (apoa2) is the second major apolipoprotein of the high-density lipoprotein cholesterol (hdl-c). the study aim was to identify apoa2 gene variation in individuals within two extreme tails of hdl-c levels and its relationship with hdl-c level. methods: this cross-sectional survey was conducted on participants from tehran glucose and lipid study (tlgs) at research ins...
Background and Objective: Profound hearing loss is one of the most prevalent congenital disorders affecting about 1 in 1000 newborns. Autosomal recessive non-syndromic hearing loss (ARNSHL) is the predominant form of the severe inherited childhood deafness. This type of hearing loss in one-half of the cases is caused by mutations in GJB2 (connexin 26) and GJB6 (connexin 30) genes located at DFN...
