Is clinical experience important for obtaining the primary stability of dental implants with aggressive threads? An ex vivo study

2018

GECKILI, ONUR/0000-0002-7852-3915; dayan, suleyman cagatay/0000-0003-3081-9618; Bilhan, Hakan/0000-0003-1787-3003 WOS:000460131200015 PubMed ID: 30818319 Background: The aim of this study was to investigate the clinicians' experience on maintaining the primary stability of implants with aggressive threads belonging to a novel dental implant system. Material and Methods: Three hundred implants with aggressive threads were inserted in fresh bovine ribs mimicking Type IV bone by five clinicians which were classified according to their previous experience of total number of implant insertion. An independent examiner measured the primary stability of all implants after insertion by using resonan…

FLUMO: FLexible Underwater MOdem

2019

The last years have seen a growing interest in underwater acoustic communications because of its applications in marine research, oceanography, marine commercial operations, the offshore oil industry and defense. High-speed communication in the underwater acoustic channel has been challenging because of limited bandwidth, extended multipath, refractive properties of the medium, severe fading, rapid time variation and large Doppler shifts. In this paper, we show an implementation of a flexible Software-Defined Acoustic (SDA) underwater modem, where modulation parameters are completely tunable to optimize performance. In particular, we develop the system architecture following two key ideas. …

Effects of weekend starvation and the duration of daily feeding on production parameters of rainbow trout Oncorhynchus mykiss

2021

It would often be practical to starve the cultivated fishes over the weekends, e.g. to save in labour costs. We evaluated the possibility that domesticated juvenile rainbow trout (Oncorhynchus mykiss) could compensate for the lost growth of the 2-day weekend starvation by either hyperphagic response and/or by lower feed conversion ratio, compared to the fish fed every day in an 8-week experiment. Rainbow trout (initial weight c. 30 g, temperature 16 °C) starved during the weekends were able to increase feed intake during the weekdays clearly above the intake of the control fish after the first two weekends, also seen as an increase of the compensation coefficients over the last four weeks o…

Multi-agent control architecture for RFID cyberphysical robotic systems initial validation of tagged objects detection and identification using Playe…

2016

International audience; The objective of this paper is to describe and validate a multi-agent architecture proposed to control RFID Cyber-Physical Robotic Systems. This environment may contain human operators, robots (mobiles, manipulators, mobile manipulators, etc.), places (workrooms, walls, etc.) and other objects (tables, chairs, etc.). The proposed control architecture is composed of two types of agents dispatched on two levels. We find at the Organization level a Supervisory agent to allow operators to configure, manage and interact with the overall control system. At the Control level, we distinguish the Robots agents, to each robot (mobiles, manipulators or mobile manipulators) is a…

Frequency Change Patterns across Proficiency Levels in Japanese EFL Learner Speech

2014

This study investigated the overall patterns of variation across seven oral proficiency levels of 1,263 Japanese EFL learners and native English speakers. The methodological approach combined a learner corpus, language processing techniques, and multivariate statistical analyses to identify patterns of language use. The largest spoken learner corpus in Japan, the National Institute of Information and Communications Technology Japanese Learner English (NICT JLE) Corpus was used for the analysis. This corpus consists of transcribed interviews with 1,281 learners and contains over one million running words of spoken English. The transcriptions were compared with data gathered from 20 native En…

Pašrunas biežuma un satura saistība ar pašefektivitāti universitātes studentiem

2020

Pētījuma mērķis ir noskaidrot pašrunas biežuma un satura saistību ar pašefektivitāti universitātes studentiem. Lai to sasniegtu, tika veikts ārvalstu zinātnisko avotu teorētiskais apskats, sniedzot pašrunas definīciju, apskatot pētījumus par pašrunu un pašrunas mērīšanas instrumentus. Detalizētāk tika apskatītas Hardija (Hardy, 2006) un Brintapa (Brinthaupts et al., 2009) pašrunas teorijas, kā arī teorija par pašrunas saistību ar vispārējo pašefektivitāti, precizāk, ar verbālo pārliecināšanu. Tika veikta divu aptauju – Pašrunas biežuma aptaujas (Self-Talk Scale (STS), Brinthaupt et al., 2009) un Ticības pašrunā aptaujas (Belief in Self-talk, Araki et al, 2006) – adaptācijas, tālāk tās izman…

Seksuālās sevis atklāšanās, seksuālā kontakta biežuma un seksuālās apmierinātības saistība pieaugušo vecumā

2021

Seksuālā apmierinātība ir seksuālās veselības un labbūtības sastāvdaļa. Pētījumā tika skatīts kāda saistība pastāv starp seksuālo apmierinātību, seksuālo sevis atklāšanas pakāpi attiecībās un vēlamā seksuālā kontakta biežuma starpību starp partneriem, kā arī to vai pastāv atšķirība attiecībā uz dzimumiem, seksuālo apmierinātību, seksuālo sevis atklāšanas pakāpi attiecībās un vēlamā seksuālā kontakta biežuma starpību starp partneriem un vai atšķirības būs tiem respondentiem, kuriem nav bērni un respondentiem, kuriem ir bērni un viņi dzīvo kopā. Pētījumā piedalījās 182 respondenti, izlasē bija 76,4% (n = 139) sievietes un 23,6% vīrieši (n = 43). 85,7% (n = 156) no aptaujātajiem respondentiem …

Temporal loudness weights are frequency specific

2021

Previous work showed that the beginning of a sound is more important for the perception of loudness than later parts. When a short silent gap of sufficient duration is inserted into a sound, this primacy effect reoccurs in the second sound part after the gap. The present study investigates whether this temporal weighting occurs independently for different frequency bands. Sounds consisting of two bandpass noises were presented in four different conditions: (1) a simultaneous gap in both bands, (2) a gap in only the lower frequency band, (3) a gap in only the higher frequency band, or (4) no gap. In all conditions, the temporal loudness weights showed a primacy effect at sound onset. For the…
