Revealing Traces of Image Resampling and Resampling Antiforensics by Anjie Peng, Yadong Wu, Xiangui Kang

“…We find that the interpolation operation used in the resampling and forged resampling makes these two kinds of image show different statistical behaviors from the unaltered images, especially in the high frequency domain. To reveal the traces left by the interpolation, we first apply multidirectional high-pass filters on an image and the residual to create multidirectional differences. …”

Conspicuous Animals Remain Alert When Under Cover but Do Not Differ in the Temporal Course of Vigilance from Less Conspicuous Species by Gerhard Hofmann, Claudia Mettke-Hofmann

“…While both species showed a high frequency of head movements (high vigilance) when sitting in an open tree, the more colourful Gouldian finch remained more vigilant than the less conspicuous long-tailed finch when sitting under cover. …”

The spectrum broadening of a single-cycle terahertz pulse caused by phase self-modulation in a nonlinear medium and the spectrum of radiation generated in its field at tripled freq... by I.R. Artser, M.V. Melnik, A.N. Tsypkin, S.A. Kozlov

“…The frequency-dependent inhomogeneity of mutual attenuation of nonlinear effects results in the absence of radiation at the triple frequency relative to the frequency of the maximum spectrum of the single-period wave in the nonlinear medium, while the maximum spectrum of the generated high-frequency radiation shifts to quadrupled frequencies. …”

Electromagnetic Waves Dispersion and Interaction of an Annular Beam-Ion Channel System in Plasma Waveguide by Jixiong Xiao, Zhijiang Wang, Jun Chen, Changhai Liu

“…In this case, compared with the solid beam case, the betatron modes not only can interact with the high frequency branch at small wavenumber but also can interact with the low frequency branch at large wavenumber.…”

Intermittent Flow Regimes in a Transonic Fan Airfoil Cascade by J. Lepicovsky, E. R. McFarland, R. V. Chima, V. R. Capece, J. Hayden

“…Experimental results revealed that, at a large incidence angle, a range of transonic inlet Mach numbers exist where the leading-edge shock-wave pattern was unstable. Flush-mounted, high-frequency response pressure transducers indicated large local jumps in the pressure in the leading edge area, which generates large intermittent loading on the blade leading edge. …”

Determination of Mapping Relation between Wheel Polygonalisation and Wheel/Rail Contact Force for Railway Freight Wagon Using Dynamic Simulation by Jian Mu, Jing Zeng, Qunsheng Wang, Hutang Sang

“…The results reveal that the low-order wheel polygonalisation except 1st order and 3rd order can give rise to high-frequency impact loads at the wheel/rail interface and excite 1st-bend modes of the wheelset and “P2 resonance” leading to high-magnitude wheel/rail contact force at the corresponding speed.…”

A Time-Discontinuous Galerkin Finite Element Method for the Solution of Impact Problem of Gas-Saturated Coal by Jingfei Zhang, Deyong Guo, Wenhua Wu, Pan Guo

“…It can effectively capture the discontinuities of the wave and filter out the effects of spurious numerical oscillation induced by high-frequency impulsive load. The results can provide a technological basis for the research of the prevention of coal and gas dynamic disasters under deep mining. …”

Fast Transient Thermal Analysis of Non-Fourier Heat Conduction Using Tikhonov Well-Conditioned Asymptotic Waveform Evaluation by Sohel Rana, Jeevan Kanesan, Ahmed Wasif Reza, Harikrishnan Ramiah

“…The non-Fourier heat conduction has been investigated where the maximum likelihood (ML) and Tikhonov regularization technique were used successfully to predict the accurate and stable temperature responses without the loss of initial nonlinear/high frequency response. To reduce the increased computational time by Tikhonov WCAWE using ML (TWCAWE-ML), another well-conditioned scheme, called mass effect (ME) T-WCAWE, is introduced. …”

Model Reduction of the Flexible Rotating Crankshaft of a Motorcycle Engine Cranktrain by Stefano Ricci, Marco Troncossi, Alessandro Rivola

“…Such a modelling approach prevents the loads at certain interface locations to be evaluated; furthermore, high-frequency dynamic effects cannot be predicted. These drawbacks can be removed by introducing bushing-like elements and/or modelling component flexibility. …”

Mechanics Design of Conical Spiral Structure for Flexible Coilable Antenna Array by Hairui Wang, Yao Zhang, Siyu Chen, Yinji Ma, Heling Wang, Ying Chen, Xue Feng

“…Compared to traditional deployable antenna, flexible coilable antenna array has higher surface precision and better vibration control and therefore is more suitable for high frequency communication. In order to minimize the weight of satellite and reduce cost of its launch, a design guideline to the geometry parameters of flexible coilable antenna array is crucial. …”

Prevalence of taurodontism: meta-analysis in recent humans and evolutionary perspectives by Pierre-Hadrien Decaup, Christine Couture, Mathieu Colin, Elsa Garot

“…Exploring and refining epidemiology of taurodontism in actual populations could strengthen the hypothesis of a selective advantage for a high attrition diet (as heavy tooth wear in Homo sapiens evolution changed little until recently) or favour pleiotropic or genetic drift effects to explain the high frequency of the trait in Neandertal remains. Prevalence ranges between 0.1% and 48% in the literature. …”

Une nouvelle procédure d’expérimentation comportementale à l’interface entre les approches « Naturalistes » et « Généralistes » de la cognition du primate by Joël Fagot

“…I (1) demonstrate that this approach allows the test of a large number of participants which participate to the research at a high frequency, (2) identify the main factors (age, day time, reinforcement rate, etc..) that affect their behavior in the tasks, (3) illustrate the effect of the test systems on the spontaneous behavior of the monkeys, and (4) briefly present two studies that used this method, in order to illustrate its potential for the Generalist and Naturalist research programs.…”
