Quantum point contacts are narrow, one-dimensional constrictions usually patterned in a two-dimensional electron system, for example by applying voltages to local gates. The linear conductance of a point contact, when measured as function of its channel width, is quantized in units of GQ = 2e(2)/h, where e is the electron charge and h is Planck's constant.(More)
Similar to Alzheimer's disease (AD), dementia with Lewy bodies (DLB) is characterized by a profound degeneration of cortically-projecting cholinergic neurons of the basal forebrain (BF) and associated depletion of cortical cholinergic activity. We aimed to investigate subregional atrophy of the BF in DLB in vivo and compare it to the pattern of BF atrophy(More)
(a) (b) Fig. 1 Illustration of a (a) double-gate FinFET with a oxide hard mask on top of the fin and a (b) tri-gate FinFET without a hard mask. Abstract— A study of designing FinFET-based SRAM cells using a compact model is reported. Parameters for a multi-gate FET compact model, BSIM-MG are extracted from fabricated n-type and p-type SOI FinFETs. Local(More)
In this paper multiuser detection techniques, such as Parallel and Serial Interference Cancellations (PIC & SIC), General Minimum Mean Square Error (GMMSE) and polynomial MMSE, for the downlink of a broadband Multi-Carrier Code Division Multiple Access (MC-CDMA) system are investigated. The Bit Error Rate (BER) and Frame Error Rate (FER) results are(More)
We study the renormalisation group running of the cosmological and the Newton constant, where the renormalisation scale is given by the inverse of the radius of the cosmological event horizon. In this framework, we discuss the future evolution of the universe, where we find stable de Sitter solutions, but also " big crunch "-like and " big rip "-like(More)
INTRODUCTION The lack of surgeons will be a future major problem in patient care for multifaceted reasons. Niche specialties such as OMFS face an additional drawback because of the need for dual qualification. Special surgical training that gives students the opportunity to gain experience in the techniques of plastic-reconstructive surgery (PRS) has(More)
This case reports the usage of human amniotic membrane combined with a costochondral graft as an interpositional material in temporomandibular joint reconstruction for the first time in humans. Because of the favorable outcome 20 months postoperatively, it has to be considered as an approach bringing to light the antiadhesive potential of amniotic membrane.(More)
