Withdrawing a non-Newtonian fluid by a moving inclined plate with account for the near-wall split effect

A fluid withdrawn by a moving inclined surface with account for the near-wall slip effect is analyzed theoretically. A non-Newtonian fluid task is stated in general form. The solving of this task enables revealing the basic physical principles and mechanisms of the process over the entire withdrawal velocity range realized in practice. The case of withdrawing a finite yield stress viscoplastic fluid is considered.

Wideband Hybrid Precoding Techniques for THz Massive MIMO in 6G Indoor Network Deployment

Terahertz (THz) communication is becoming an up-and-coming technology for the future 6G networks as it provides an ultra-wide bandwidth.Appropriate channel models and precoding techniques are essential for supporting the desired coverage and mainly to resolve the severe path loss in THz signals. Initially, the Sub-THz channel (140 GHz) impulse response by using NYUSIM Channel Simulator for 6G indoor office scenario is investigated in this work. The highlight is on Large scale and Small scale parameters like propagation delay and path loss, antenna array gain, etc. The beam split effect is a critical challenge of THz wideband communication.Therefore We have proposed three different THz precoding methodologies like the hybrid precoding, analog beamforming, and the delay-phase precoding to address this challenge. We then extensively investigate its diverse number of time delayers, varying number of antenna elements, and comparison with frequency - mmWave and Sub-THz have been discussed. Finally, the proposed delay-phase precoding techniques outperforms the other precoding techniques with 97% of optimal precoding. So, this an efficient approach for implementing the future indoor communication network deployment for 6G.

Silence-cued stop perception: Split decisions

Bastian, Eimas, & Liberman (1961) found that listeners heard a [p] when a silence of more than 50ms was inserted between the [s] and the [l] in a recording of the word slit. It has long been known that silence is an important cue in stop consonant perception. Nevertheless, it is surprising that a short interval of silence can substitute for something as acoustically and articulatorily complex as a phoneme. In the present work, we replicate and expand upon this study to further examine the phenomenon of silence-cued stop perception. We demonstrate the ‘Split Effect’ in a previously unexplored set of environments, analyze factors that contribute to the identity of silence-cued stops, and lay the groundwork for further investigation of the acoustic and non-acoustic factors that contribute to this perceptual illusion. Our study demonstrates an experimental paradigm for studying the genesis of such effects synchronically and in a controlled setting.
