The explosive progress of Deepfake techniques poses unprecedented privacy and security risks to our society by creating real-looking but fake visual content. current detection studies are still in their infancy because they mainly rely on capturing artifacts left a synthesis process as clues, which can be easily removed various distortions (e.g. blurring) or advanced techniques. In this paper, we propose novel method that does not depend identifying the resorts mechanism anti-counterfeit...

Foreigner-directed speech is a much cited style, but its acoustic properties are surprisingly under-studied, and many existing studies evoke imagined interlocutors to elicit foreigner-directed speech. This study provides an comparison of native-directed in real imaginary conditions. Ten native English speakers described the path between landmarks on map each two confederate listeners (one speaker one Mandarin speaker) as other non-native speaker). Vowel duration, rate speech, vowel...
Purpose: Knee joint is one of the largest and most complex joints body. diseases are common, current clinical imaging technologies such as x‐ray computed tomography, magnetic resonance imaging, ultrasound have limitations in diagnosis knee diseases. Emerging diffuse optical tomography photoacoustic (PAI) been applied to detection osteoarthritis (OA). However, they limited small finger difficult be used for large knee. Thermoacoustic (TAI), also an emerging modality, provides high contrast...
Abstract Biochar is widely used in agricultural production because of its ability to improve the physical and chemical properties soil promote crop growth. In this study, a combination different biochar lake sediments were saline soils. The four raw materials, including corn stalk chicken manure liquefaction product (SMLP), rice husk charcoal (RHC) two types sediment (S‐1 S‐2), which was saline–alkali soil, respectively. most significantly effective applied on when composite conditioner...
We present for the first time in vivo imaging of rat brain using microwave-induced thermoacoustic tomography (TAT). The was realized through an unconventional delivery microwave energy from front (while transducer scanned along coronal plane animal brain), which maximized penetration into brain. In addition, we found that contrast highly dependent on direction electric field polarization (EFP) and more tissue structures/compositions could be revealed when both [Formula: see text]- text]-EFPs...
In this study, we present the design, fabrication, and evaluation of a curved-array-based photoacoustic imaging system designed for vasculatures inside human finger joints with multispectral strategy.The transducers were fabricated polyvinylidene fluoride (PVDF) film size 30 mm × 2.8 curvature radius 82 mm. A detailed comparison between PVDF transducer commercial piezoelectric ceramic was performed. addition, phantom in vivo mouse experiments carried out to evaluate performance. Furthermore,...
Electroactive membranes have the potential to address membrane fouling via electrokinetic phenomena. However, additional energy consumption and complex material design represent chief barriers achieving sustainable economically viable antifouling performance. Herein, we present a novel strategy for fabricating piezoelectric polyvinylidene fluoride (PVDF) (Pi-UFM) by integrating ion-dipole interactions (NaCl coagulation bath) mild poling (in situ electric field) into one-step phase separation...
Abstract Stem cell‐based therapies provide a promising approach for bone repair. In the present work, we developed novel 3D vehicle system dual‐delivery of encapsulated marrow mesenchymal stem cells (BM‐MSCs) and morphogenetic protein‐2 (BMP‐2) treatment large defects. The consists sodium alginate microcapsules polylactic acid (PLLA) microspheres. BM‐MSCs are in microcapsules, BMP‐2 proteins PLLA This acted as multicore structure sustained release BMP‐2, which enabled pulsed dosing induction...
The infiltration of adipocytes in osteoporotic patients' bone marrow suggests an important regulatory function fat on the development aged bone. Therefore, we have examined effects derived from mesenchymal stem cell (MSC) osteoblast differentiation using two different co-culture modes (direct mode and indirect mode). Alkaline phosphatase (ALP)-positive areas mineralized MSC-derived osteoblasts decrease similarly as amount MSCderived increases, suggesting that crosstalk between may be mainly...
Abstract Prenatal ethanol exposure (PEE) can lead to structural and functional abnormalities in fetal brain. Although neural developmental deficits due PEE have been recognized, the immediate effects of on brain vasculature hemodynamics remain poorly understood. One major obstacles that preclude rapid advancement studies vascular dynamics is limitation imaging techniques. Thus, a technique for noninvasive in‐vivo desirable. In this study, we explored dynamic changes vessel dimeter, density...
Microwave-induced thermoacoustic tomography (TAT) has potential for detecting germinal matrix hemorrhage (GMH). However, it not been demonstrated in vivo.To demonstrate the feasibility of TAT vivo GMH by using neonatal mouse.A cylindrical-scanning system was developed with optimized microwave irradiation and ultrasound detection mouse imaging. Neonatal mice were used to develop model injection autologous blood into periventricular region. After experiments, animals sacrificed, frozen excised...
Photoacoustic (PA) imaging provides unique advantages in peripheral vascular due to its high sensitivity hemoglobin. Nevertheless, limitations associated with handheld or mechanical scanning by stepping motor techniques have precluded photoacoustic from advancing clinical applications. As applications require flexibility, affordability, and portability of equipment, current systems developed for usually use dry coupling. However, it inevitably induces uncontrolled contact force between the...
Abstract Laser interaction with doped crystals exhibiting photon–photon and photon–phonon coupling has been focused on recently. In pretext, here we report the spectral temporal profile of two lasers excitation through various phases Eu 3+ : BiPO 4 crystals. We reveal that spectral-temporal hybrid signals (coexisting fluorescence spontaneous four-wave mixing) are dressed by nested cascade processes two-photons (two-phonon). Such comes from thermal phonon constructive phase transition...
Abstract The grid connection of a mass distributed power sources in the AC/DC hybrid micro-grid will cause harmonics, voltage sags, fluctuations, and flicker grid, which seriously affects quality grid. Therefore, problems such as resonance generated by need to be studied urgently. In this paper, detection technology based on combination wavelet transform (WT) fast Fourier (FFT) is proposed. This method uses process high-frequency low-frequency parts signal separately, eliminates part...
