The inverse problem of determining a region in which the velocities of magnetic particles or biological cells modified by these particles (microaggregates) vanish has been formulated and solved. The zerovelocity isolines have been determined for three variants of arrangement of a permanent magnet. A solution of the in…
The images on the inside back cover refer to the article by Dawei Xing et al. (pp. 1905–1910). They show the critical behavior for melt-extracted Gd-based microwires. The authors investigated Gd60Co15Al25 wires with an average diameter of 40 μm that underwent a second-order paramagnetic to ferromagnetic (PM–FM) transi…
Ultrasonic pulse-echo technique is a valuable and non-destructive tool to explore elastic properties of materials. We propose a new instrument based on mass-produced microchips. In our design, the signal is processed by an AD8302 RF gain and phase detector (www.analog.com). Its phase output is linearly proportional to…
A large variety of pipe flange is required in marine and construction industry. Pipe flanges are usually welded or screwed to the pipe end and are connected with bolts. This approach is very simple and widely used for a long time; however, it results in high development cost and low productivity, and the productions m…
Se realizó un estudio comparativo del efecto que produce la adición de agentes de acoplamiento tipo silanovinyltrimethoxysilano y 3-aminopropiltrietoxisilano sobre la mezcla de etilenvinilacetato con harina de TelinneMonspessulana. La incorporación de agentes de acoplamiento se hizo de manera directa sobre la mezcla e…
The methods for optimization of energy exchange between the linear and nonlinear capacitors are proposed. As an example we consider the equivalent circuit of the supercapacitor, electric capacity of which changes proportionally to the voltage on its plates. It is shown that the electric power losses in the energy exch…
Abstract In this paper, we present a moiré display based on the finite distance effect, which has two non‐coplanar layers installed at a non‐zero gap.
Abstract We successfully demonstrate a 1.89‐inch SLMoG (spatial light modulator on glass) driven by oxide BCE (back channel etch) TFTs (thin‐film transistor). It is necessary for SLM to have very fine pixel pitch and large panel size for realizing high display quality of digital holography. To confirm such technical d…
Strength properties and the yield of soda and soda-ethanol pulps produced using hornbeam, beech and poplar woods were investigated. Soda pulps were produced applying 20% active alkali and the soda-ethanol pulps were made using 10% active alkali and 50% ethanol. The pulping temperature was constant at 175 C and the sod…
Abstract We demonstrate low‐cost, efficient indium tin oxide (ITO)‐free organic light‐emitting diodes (OLEDs) with improved stability based on conductive, transparent poly(3,4‐ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) electrodes. The device structures are carefully optimized by tuning the thickness of…
Abstract We demonstrate the fabrication of a large‐scale device allowing for electrical switching of polarized light with a polarization ratio of 0.45 over a 1.5 cm2 area. To achieve this, a film of aligned polymeric nanofibers containing aligned silica‐coated semiconductor nanorods was prepared by electrospinning. Th…

In this report the Bi-doped silica fiber (BDF) is fabricated by the vapor-phase axial deposition (VAD) method. A wide range optical amplified gain is measured in 1300–1600 nm with the BDF. 7dB gain is achieved with 4m D-shaped first-clad fiber at 1310 nm.

A scalable contact-transfer printing of an ultrasensitive, flexible nanoplasmonic biosensing platform for miRNA-21 is presented by J.-S. Yeo and co-workers in article number 1500121. The greatly increased sensitivity and suppressed noise result from selective pre-functionalization on the sidewalls of the nanostructure…
The optimization approach to voltage harmonic elimination is presented. The parallel filter used for the voltage shape improving in three-phase four wire systems is considered. The nonlinear inductor is applied as a source of current and voltage harmonics. Two cases are considered-harmonic reduction and unbalanced loa…
The paper presents the results of mathematical modeling of a strong electric field (EF) in a cross-linked polyethylene (XLPE), which conductivity is a nonlinear function of the field strength. The analysis of changes in the gain coefficients of EF and total current density increase near water micro-trees, occurring on…

Thus, the experimental and numerical studies of electromagnetic properties of layered chiral media in the millimeter waveband are carried out. It is shown that the chiral structure based on rosettes massive exhibits the left-handed properties for one of the circularly polarized waves. This is manifested the negative f…
Histotripsy has been demonstrated as a non-invasive, drug-free, image-guided thrombolysis method using cavitation alone. Microtripsy is a new histotripsy approach, where cavitation is generated using 1-cycle ultrasound pulses with negative pressure exceeding a threshold intrinsic to the medium. We hypothesize that, us…
