Reconfigurable intelligent surfaces (RISs) have the potential of realizing emerging concept smart radio environments by leveraging unique properties metamaterials and large arrays inexpensive antennas. In this article, we discuss applications RISs in wireless networks that operate at high-frequency bands, e.g., millimeter wave (30-100 GHz) sub-millimeter (greater than 100 frequencies. When used networks, may a manner similar to relays. The present paper, therefore, elaborates on key...
Abstract Versatile strategies have been developed to construct electrospun fiber-based drug delivery systems for tissue regeneration and cancer therapy. We first introduce the construction of fiber scaffolds their various structures, as well commonly used types drugs. Then, we discuss some representative controlling by fibers, with specific emphasis on design endogenous external stimuli-responsive systems. Afterwards, summarize recent progress engineering, including soft engineering (such...
Objective.Reliable and user-friendly electrodes can continuously real-time capture the electroencephalography (EEG) signals, which is essential for real-life brain-computer interfaces (BCIs). This study develops a flexible, durable, low-contact-impedance polyvinyl alcohol/polyacrylamide double-network hydrogel (PVA/PAM DNH)-based semi-dry electrode robust EEG recording at hairy scalp.Approach.The PVA/PAM DNHs are developed using cyclic freeze-thaw strategy used as saline reservoir...
Abstract Soil and groundwater contamination has always been a global concern. Contaminants are migrated transformed in the soil environments, which turn pose potential environmental risks to humans. This paper describes four typical contaminants, including heavy metals, polycyclic aromatic hydrocarbons, microplastics, perfluorinated polyfluoroalkyl substances. Based on systematic summary of sources, hazards, migration behaviors these various existing remediation methods analyzed, advantages...
Secondary Wall-Associated NAC Domain 1s (SND1s) are transcription factors (TFs) known to activate a cascade of TF and pathway genes affecting secondary cell wall biosynthesis (xylogenesis) in Arabidopsis poplars. Elevated SND1 transcriptional activation leads ectopic xylogenesis stunted growth. Nothing is about the upstream regulators SND1. Here we report discovery stem-differentiating xylem (SDX)-specific alternative splice variant, PtrSND1-A2(IR), that acts as dominant negative network...
An emerging and promising vision of wireless networks consists coating the environmental objects with reconfigurable metasurfaces that are capable modifying radio waves impinging upon them according to generalized law reflection. By relying on tools from point processes, stochastic geometry, random spatial we model a modified line process fixed length orientations locations. Based proposed modeling approach, develop first analytical framework provides one probability randomly distributed...
Abstract It was a physicist, Wolfgang Pauli, who recognized century ago that “God made the bulk; surface invented by devil.” And indeed, adjusting properties of materials has kept engineers and chemists busy since—and it still does. In context biomedical engineering, key challenge is ensuring functionality an artificial object, which inserted into human body—an environment passively actively rejects foreign materials. Here, recent advances in this area while focusing on those approaches...
Perineuronal nets (PNNs), a complex of extracellular matrix molecules that mostly surround GABAergic neurons in various brain regions, play critical role synaptic plasticity. The function and cellular mechanisms PNNs memory consolidation reconsolidation processes are still not well understood. We hypothesized protect long-term by limiting feedback inhibition from parvalbumin (PV) interneurons to projection neurons. Using behavioral, electrophysiological, optogenetic approaches, we...
It is of great importance to treat a bacterial-infected wound by smart dressing capable delivering antibiotics in manner without causing drug resistance. The construction release nanocontainers responsive near-infrared (NIR) laser irradiation an on-demand and stepwise way promising strategy for avoiding the emergence multidrug-resistant bacteria. Here, we develop hydrogel composite made alginate nanotubes with efficient NIR-triggered rifampicin outstanding antibacterial ability. This...
The application of pressure-sensitive adhesives (PSAs) in transdermal drug delivery systems (TDDSs) is limited. Insufficient cohesion TDDS can lead to cold flow, patch displacement, dose inaccuracies, and the 'dark ring' phenomenon. To address these issues, we developed a semi-interpenetrating network (semi-IPN) PSA using 2-hydroxyethylacrylate-modified acrylic copolymer as linear polymer poly[tri(propylene glycol) diacrylate] cross-linked network. Semi-IPN PSAs have better mechanical...
Mycobacterium tuberculosis has two genes for ferric uptake regulator orthologues, one of which, furA , is situated immediately upstream katG encoding catalase–peroxidase, a major virulence factor that also activates the prodrug isoniazid. This association suggested might regulate and other involved in pathogenesis. Transcript mapping showed to be expressed from strong promoter, with consensus −10 −35 elements, preceding . No promoter activity was demonstrated downstream start codon, using...
In several bacteria, the catalase–peroxidase gene katG is under positive control by oxyR , a transcriptional regulator of peroxide stress response. The Mycobacterium tuberculosis genome also contains sequences corresponding to but this has been inactivated in tubercle bacillus because presence multiple mutations and deletions. Thus, M. possibly other parts oxidative response organism are either not regulated or controlled factor different from OxyR. mycobacterial FurA homologue ferric uptake...
PN-sequence padding (PNP) TDS-OFDM transmission scheme has recently been proposed as an appealing alternative to the traditional cyclic prefix (CP) OFDM technology it can provide significant improvement in spectrum efficiency. In this paper, iterative method is introduced subtract PN sequence for systems mitigate residual inter symbol interference (ISI) from imperfect channel estimation, and inherent estimation techniques are also performed track changes. Results show that algorithm...

In this study, atmospheric emissions from zinc, lead and copper smelters between 2000–2010 were estimated using a technology-based methodology with comprehensive consideration concentration concentrates, processes, removal efficiencies air pollution control devices (APCDs) application percentage certain type APCD combinations....
Abstract The complex, gradient physiological structure of articular cartilage is a severe hindrance its self‐repair, leaving the clinical treatment defects demanding issue to be addressed. Currently applied tissue engineering treatments and traditional non‐tissue have different limitations, for example, cell dedifferentiation, immune rejection, prosthesis‐related complications. Thus, studies been focusing on seeking promising candidates novel repair methods. Polyvinyl alcohol (PVA) hydrogels...
Infected wounds pose a significant clinical challenge due to bacterial resistance, recurrent infections, and impaired healing. Reactive oxygen species (ROS)-based strategies have shown promise in eradicating infections. However, the excess ROS infection site after treatments may cause irreversible damage healthy tissues. To address this issue, we developed bovine serum albumin-iridium oxide nanoclusters (BSA-IrO
Nanotribology has been given increasing attention by researchers in pursuing the nature of friction. In present work, an approach that combines supramolecular assembly and nanotribology is introduced. Herein, nanotribological study was carried out on seven template networks [namely, hydrogen bond induced tricarboxylic acids van der Waals force hexaphenylbenzene (HPB) derivatives]. The networks, as well host–guest assemblies molecules different forces, were constructed highly oriented...
Abstract Even though medical devices have improved a lot over the past decades, there are still issues regarding their anti‐biofouling properties and tribological performance, both aspects contribute to short‐ long‐term failure of these devices. Coating with biocompatible layer that reduces friction, wear, biofouling at same time would be promising strategy address issues. Inspired by adhesion mechanism employed mussels, here, dopamine is made use immobilize lubricious mucin macromolecules...
