Dynamic metasurface antennas (DMAs) have great potential to be used in the radiator/receptor elements of future wireless transmitters and receivers, replacing conventional metallic antennas. This can attributed their unique properties, such as ability reconfigured real-time reduce radio frequency chains, resulting low implementation cost. However, Lorentzian constraint associated with DMA poses...

Abstract. Ambient measurements combined with theoretical simulations have shown evidence that the tropospheric degradation end-products of Freon alternatives, trifluoroacetic acid (TFA), one most important and abundant atmospheric organic substances, can enhance nucleation process based on sulfuric (SA) dimethylamine (DMA) in urban environments. However, TFA is widespread all over world under d...

Background Cryopreservation procedure for poultry semen is not reliable due to structural and biochemical damages which can lead to reduction in sperm quality and fertility. Development of cryopreservation medium has crucial effects for successful recovery of sperm after freezing. The objective of this study was assessment of cryopreservation of rooster semen using hand-made cryopreservation me...

The assemblies of tetrahedral linker tetrakis[4-(carboxyphenyl)oxamethyl]methane acid (H(4)L) with ZnCl(2) and CdBr(2) yield two noncentrosymmetric, NLO-active coordination polymers [Zn(4)(L(2))(H(2)O)(3)(DMA)].2H(2)O (1) and [Cd(2)L(DMA)(2)(H(2)O)(2)] (2), respectively. 1 has an unprecedented 2-fold interpenetrating sxa topology with ferroelectric properties, while 2 has a 7-fold interpenetrat...

The dynamical mechanical analysis (DMA) technique was used for the characterization of some recently manufactured and historical parchments and leathers. The obtained results were correlated with the DSC measurements performed for these biomaterials. We point out the suitability of the DMA method for distinguishing qualitatively between a recently manufactured leather and a patrimonial one, as ...

The U.S. Environmental Protection Agency (EPA) Engineering Issue Papers (EIPs) are a series of documents that summarize the available information on specific contaminants, selected treatment and site remediation technologies, and related issues. This EIP is intended to provide remedial project managers (RPMs), on-scene coordinators (OSCs), contractors, and other state or private remediation man...

We demonstrate the applicability of integrated sensing and processing decision trees (ISPDTs) methodology to a set of digital mirror array (DMA) hyperspectral imagery. In particular, we demonstrate that ISPDTs can be used to detect and localize targets by using just a few DMA Hadamard frames, so that an entire hyperspectral data cube need not be collected to successfully perform the given task....

Extracellular adhesion molecules and their neuronal receptors guide the growth and branching of axons and dendrites. Growth cones are attracted to intermediate targets, but they must switch their response upon arrival so that they can move away and complete the next stage of growth. Here, we show that KPC-1, a C. elegans Furin homolog, regulates the level of the branching receptor DMA-1 on dend...

AbstracG-Crystal morphology of thermoplastics is known to be strongly influenced by the presence of solid suhstrntes like fibers or fillers. For wood, this interphase development is govemed by the chemical composition of the thermoplastic and substrate. The crystallization of PP/MAPP blends WBS observed using polarized light microscopy and quantified using DSC and DM.4. Techniques are presented...

Computer system IO (with accelerator, network, storage, graphics components) has been optimized to use descriptor-based direct memory access (DMA) operations to move data to and from relatively fast addressable system (or main) memory or cache structures. Traditionally, transactions between slower IO sub-systems and system memory have been done using a host bus/bridge adapter (HBA). Each IO int...
