This paper presents an acoustic study of the phonetic realization of two consonants in Nias (Indonesia), orthographically represented as mb and ndr. These consonants have been analyzed by Catford (1988) and Brown (2001, 2005) as a bilabial trill and an apical trill, respectively. My own cross-dialectal observations indicate that these consonants have multiple realizations in each dialect. This ...

This talk presents results of weak matrix elements calculated from simulations done on 170 32 × 64 lattices at β = 6.0 using quenched Wilson fermions. We discuss the extraction of pseudoscalar decay constants fπ, fK , fD, and fDs , the form-factors for the rare decay B → K ∗γ, and the matrix elements of the 4-fermion operators relevant to BK , B7, B8. We present an analysis of the various sourc...

Two terminal metal–oxide–metal devices based on niobium oxide thin films exhibit a wide range of non-linear electrical characteristics that have applications in hardware-based neuromorphic computing. In this study, we compare the threshold-switching and current-controlled negative differential resistance (NDR) cross-point fabricated from undoped Nb2O5 Ti-doped show doping offers an effective me...

In this paper, we propose a new heterostructure dual material gate junctionless field-effect transistor (H-DMG-JLFET), with negative differential resistance (NDR) characteristic. The drain and channel material are silicon and source material is germanium. The gate electrode near the source is larger. A dual gate material technique is used to achieve upward band bending in order to access n-i-p-...

We tested the electrical characteristics of an oligo phenylene ethynylene OPE molecule with one nitro side group, an OPE with two nitro side groups, and an OPE with no nitro side groups in our nanowell device. The OPE molecule with nitro side group s showed switching behavior with memory as well as nonreversible negative differential resistance NDR . Current-voltage I-V characteristics showed a...

There has been an increasing awareness of the need to pay special focus on the adolescent and their sexual and reproductive health. This article reviews the sexual and reproductive health of adolescents in the Niger Delta region (NDR) of Nigeria. The objective is to bring to focus these important issues in the region. Adolescents in the NDR engage in unhealthy sexual behaviour characterized by ...

We report an experimental study of the electrical properties of single-barrier Hg 1 _ x Cdx Te heterostructures grown by molecular-beam epitaxy. At high temperature, the measured current is interpreted to be the sum of thermionic and tunneling hole currents. This analysis is applied to data from each of three samples, yielding values of the HgTe-CdTe valence-band discontinuity between 290 ± 50 ...

A newly structured triple-well resonant tunneling diode (RTD) is proposed as a triple-valued logic device. The superiority of this new RTD for triple-valued logic application i s demonstrated with numerical simulation based on the transfer matrix method. This new RTD exhibits significant double-negative differential resistance, and the two current peak voltages are independently controlled with...
