AbstractWe show that for any pair of elliptic curves E1, E2 over ℚ with j-invariant equal to 0, we can find a polynomial D ∈ ℤ[u, v] such that the cubic twists of the curves E1, E2 by D(u, v) have positive rank over ℚ(u, v). We also prove that for any quadruple of pairwise distinct elliptic curves Ei, i = 1, 2, 3, 4, with j-invariant j = 0, there exists a polynomial D ∈ ℤ[u] such that the sextic twists of Ei, i = 1, 2, 3, 4, by D(u) have positive rank. A similar result is proved for quadruplets of elliptic curves with j-invariant j = 1, 728.

Abstract:

Recently V. Arnold introduced Strangeness and J± invariants of generic immersions of an oriented circle to ℝ2. Here these invariants are generalized to the case of generic immersions of an oriented circle to an arbitrary surface F. We explicitly describe all the invariants satisfying axioms, which naturally generalize the axioms used by V. Arnold.

Abstract In this work, we developed a simple and direct circuit model with a dual two-diode model that can be solved by a SPICE numerical simulation to comprehensively describe the monolithic perovskite/crystalline silicon (PVS/c-Si) tandem solar cells.

The effects of the individual efficiency-loss mechanism on the tandem cell’s efficiency are discussed, including the exp(V/V T) and exp(V/2V T) recombination

Basic data in colour vision such as chromatic response curves were obtained with aperture colours.

The results by an improved method are presented.

Measurements show that for low voltage, the current versus voltage (j x V) characteristics presents an exponential increasing, typical of a diode behavior.

Since the donor plays a critical role as the absorber to solar photon flux, donor materials require wide optical absorption to match the solar spectrum.

【Background】 The need for Lithium-ion batteries (LIBs) with longer life is growing with the popularization of their applications, but LIBs lose capacity with use.

The reduction of a positive and a negative electrode capacity is caused by deactivation of active materials due to decrease in the conducting paths of electrons and

ABSTRACT We collect the long-term γ-ray, optical, and radio 15 GHz light curves of quasar object PMN J2345−1555, and make correlation analyses between them. We find that different samplings can lead to different time delays, and the periodicity of light curves can produce signals that are beyond 3σ significance level. The optical V and R band and the infrared J band light curves lead the radio 15 GHz light curve by $49^{+15}_{-12}$ d. There is no lag between the optical and γ-ray light curves. We use the time lags to derive the core size and its uncertainty. We find that the core region of 15

Abstract:

We investigated the longitudinal dispersion of helium (He), methane, acetylene, butane, sulfur hexafluoride, and octafluorocyclobutane (C4F8) in a clear plastic model of the human bronchial airways. The dimensions of the seven airway generations (0–6) of the model were chosen to be equal to those given by Weibel's model A (Morphometry of the Human Lung; New York: Academic, 1963). Total volume of the model amounts to 52 ml. A small bolus of each of the tracer gases was injected within 1 ms into a constant airflow at the inlet of the model, and the bolus dispersion curve was measured at the outl

Abstract:

Laser-deposited Fe2O3 films or dye-fixed TiO2 films were prepared for solar cells. For both the cells, a single walled carbon nanotube (SWNT) film or a Pt-loaded SWNT film, prepared by simply pasting over ITO glass, was used as a counter electrode. Stable current (I)-voltage (V) curves were found under UV-visible light irradiation using water containing KI and I2 as an electrolyte. A comparison of I-V curves was made for Pt alone and SWNT alone films used as a counter electrode. Almost similar efficiency was found by using both types of counter electrodes. However, enhanced efficiency was obta

Monolayer Langmuir–Blodgett (LB) films of 1,4-bis(pyridin-4-ylethynyl)benzene (1) together with the “STM touch-to-contact” method have been used to study the nature of metal–monolayer–metal junctions in which the pyridyl group provides the contact at both molecule–surface interfaces. Surface pressure vs area per molecule isotherms and Brewster angle microscopy images indicate that 1 forms true monolayers at the air–water interface. LB films of 1 were fabricated by deposition of the Langmuir films onto solid supports resulting in monolayers with surface coverage of 0.98 × 10−9 mol·cm−2. The mor

We studied the contribution of inter- and intraregional inhomogeneities of specific ventilation (delta V/Vo) from the rebreathing inert gas trace in microgravity and on Earth. The rebreathing tests were carried out by four astronauts before, during, and after the 10-day Spacelab D-2 mission. Starting from functional residual capacity, the rebreathing maneuver consisted of eight reinspirations from a bag filled with 1.8-2.2 liters of test gas mixtures containing approximately 5% argon. The rate of argon equilibration in the rebreathing bag, termed RBeq, was quantified by determining the logarit

Abstract:

The present work aims to fabricate n-i-p forward perovskite solar cell (PSC) withئ structure (FTO/ compact TiO2/ compact TiO2/ MAPbI3 Perovskite/ hole transport layer/ Au). P3HT, CuI and Spiro-OMeTAD were used as hole transport layers. A nano film of 25 nm gold layer was deposited once between the electron transport layer and the perovskite layer, then between the hole transport layer and the perovskite layer. The performance of the forward-perovskite solar cell was studied. Also, the role of each electron transport layer and the hole transport layer in the perovskite solar cell was presented.

Abstract:

Abstract During the prompt phase, Poynting-flux-dominated jets undergo acceleration accompanied by magnetic dissipation. By using an outward-propagating thin-shell model, where bulk Lorentz factors Γ increase with radius and the magnetic field strength decay is related to the acceleration and the energy conversion rate, this process can be investigated through time-resolved polarization analysis. Faster acceleration produces a greater flux, steeper light-curve growth followed by a sharper decline, and polarization degree decreases sharply. With a fixed acceleration index, lower energy conversi

Given the environmental forcing by extremes in hypoxia-reoxygenation, there might be no genetic effect on posthypoxic short-term potentiation of ventilation. Minute ventilation (V˙e), respiratory frequency (f), tidal volume (Vt), and the airway resistance during chemical loading were assessed in unanesthetized unrestrained C57BL/6J (B6) and A/J mice using whole body plethysmography. Static pressure-volume curves were also performed. In 12 males for each strain, after 5 min of 8% O2 exposure, B6 mice had a prominent decrease inV˙e on reoxygenation with either air (−11%) or 100% O2 (−20%), due t

The problem of forced convection transpired turbulent boundary layers with external pressure gradient has been studied by using different scalings proposed by various researchers. Three major results were obtained: First, for adverse pressure gradient boundary layers with suction, the mean deficit profiles collapse with the free stream velocity, U∞, but into different curves depending on the strength of the blowing parameter and the upstream conditions. Second, the dependencies on the blowing parameter, the Reynolds number, and the strength of pressure gradient are removed from the outer flow

The n-value is observed to fall with increased applied magnetic field and temperature, and exhibits the thermally activated flux flow behavior. The activation energies U(T, H, J) derived from the V-I curves were found to follow a (n − 1)k B T × ln (J0/J). The critical temperatu
