Contact-Induced Convergence: Typology and Areality

2006

From an integrative perspective, research on language typology and research on areality understood in terms of contact-induced convergence are mutually dependent. Typologists need to be aware that their generalizations are as reliable as they manage to integrate effects of contact into their statistics. Contact linguists need to be aware that typological findings may not qualify as independent evidence for their field. Thus, typologists and contact linguists both need to have certain information concerning each other's field. For that reason, this article covers both fields under one title. The article is divided into three main sections. The first deals with language contact and its struct…

Spin Switching in Molecular Quantum Cellular Automata Based on Mixed-Valence Tetrameric Units

2016

In this article we focus on the study of spin effects in a single square-planar mixed-valence cell comprising two electrons and in coupled molecular cells for quantum cellular automata. Using the vibronic model we demonstrate that the polarizabilities of the cell are different in spin-singlet and spin-triplet states of the electronic pair. Based on this inference the concept of spin switching in molecular quantum cellular automata is proposed, and the conditions under which this effect is feasible are derived. In order to reveal these conditions we have performed a series of quantum-mechanical calculations of the vibronic energy levels of the isolated cell and of the cell subjected to the e…

Optimal configuration for size-based burst assembly algorithms at the edge node for video traffic transmissions over OBS networks

2008

Optical burst switching (OBS) has been proposed to be a technology for implementing the next generation optical Internet. In this architecture, burst assembly algorithms have an important influence in the pattern traffic that characteristic this sort of optical networks. On the other hand, traffic coming from new applications (such as video on demand, Voice over IP, online gaming or Grid computing) that have real time and bandwidth constraints, has been experimented a rapid increment. Consequently, we consider important to evaluate the performance of traffic from real time applications over OBS networks. In this paper, we evaluate the effects of implementing a size-based burst assembly sche…

Effect and optimization of burst assembly algorithms for video traffic transmissions over OBS networks

2008

Optical burst switching (OBS) has been proposed to be a technology for implementing the next generation optical Internet. In this architecture, burst assembly algorithms have an important influence in the traffic pattern that characterizes this sort of optical networks. On the other hand, traffic coming from new applications (such as video on demand, Voice over IP, online gaming or Grid services) that have real time and bandwidth constraints has been experimented a rapid increment. Consequently, we consider important to evaluate the performance of the real time traffic over OBS networks. In this paper, we evaluate the video transmissions performance (MPEG4/RTP/UDP) over OBS networks, for bo…

An experimental analysis of self-Q-switching via stimulated Brillouin scattering in an ytterbium doped fiber laser

2013

An experimental study of self-Q-switching (SQS) in an ytterbium doped fiber laser (YDFL) arranged using a twin-core GTWave assembly is reported. The main mechanisms that initiate, amplify, and limit SQS pulses in amplitude are revealed to be stimulated Brillouin and Raman scattering (SBS/SRS) and Yb3+ amplified spontaneous emission. The parameters featuring SQS oscillation in terms of efficiency and stability of pulsing are found to be intra-cavity loss and feedback strength. An analysis of the YDFL SQS regime?s features?pulsing time series, optical and RF spectra, amplitude and timing jitter?is provided for the two experimental situations: (i) when SQS pulsing stochastically intermits with…

Effect of internal noise on the relaxation time of an yttria stabilized zirconia-based memristor

2022

The effects of temperature on the switching kinetics of an yttrium-stabilized zirconia-based memristor from a low-resistance state to a high-resistance state have been experimentally investigated. It was found that the memristor relaxation time depends on the temperature in a non-monotonous way, with a maximum observed at the temperature close to 55 °C. This nonmonotonic behavior is a signature of the noise-enhanced stability phenomenon observed in all physical and complex systems characterized by metastable states.

Pulse timing effects in bulk Er/Yb codoped diode-pumped eyesafe lasers

2007

In this work, diode-pumping with appropriately modulated pulses is used to expose subtle input / output pulse-timing characteristics of Er3+ /Yb3+ systems, study their relation to laser efficiency and demonstrate some unique laser-pulse timing behavior. Er+3/Yb+3 codoped glass and YAG laser-host materials with similar concentrations (optimized for eyesafe emission in the 1.6-mum region) were studied in the same diode-pumped setup, in similar resonator configurations and analogous operating conditions.

The two-factor structure of cognitive flexibility : tempo of switching and overcoming of prepotent responses

2023

Prezentowane badanie miało na celu odkrycie struktury procesów latentnych leżących u podstaw wykonania kilku zadań, które hipotetycznie mierzą spontaniczną i adaptacyjną giętkość poznawczą, dostarczając dowodów na ich trafność zbieżną. Grupa zdrowych ochotników (N = 121) ukończyła dwa zestawy zadań do oceny spontanicznej i adaptacyjnej giętkości poznawczej. Spontaniczna giętkość poznawcza obejmowała test myślenia dywergencyjnego (do oceny płynności i giętkości myślenia) oraz werbalny test płynności. Miary giętkości adaptacyjnej obejmowały test przełączania się między zadaniami jako miarę kosztów przełączania oraz test przerzucania uwagi jako miarę wyuczonej nieistotności i perseweracji. Nat…
