The article focuses on comparing consumer journeys and brand relationships across the microblogging platforms X and Threads. Topics include differences in brand awareness, engagement, and usage on X versus Threads; the impact of platform features on consumer purchase behavior and loyalty; the need for tailored marketing strategies for each platform; and the study reveals that Threads excels in awareness and community engagement, while X offers broader reach and higher purchase rates.

In this paper we present the design overview of the UAV-based P- (repeat-pass) and X-band (single-pass) interferometric SAR system of OrbiSat, Brazil. The main objective is to built a compact and flexible InSAR system capable of performing accurate topographic survey and differential interferometry. To our knowledge, this is the first UAV-based In-SAR system with such characteristics, multi-band and fixed-baseline (X-band), to be projected. The status, and some main project results and solution are described and depicted. [ABSTRACT FROM PUBLISHER]

Safety is a prime concern for the photovoltaics (PV) industry. As a technology deployed on residential and commercial buildings, it is critical that PV not cause damage to the buildings nor harm the occupants. Many of the PV systems on buildings are of sufficiently high voltage (300 to 600 Volts dc) that they may present potential hazards. These PV systems must be safe in terms of mechanical damage (nothing falls on someone), shock hazard (no risk of electrical shock when touching an exposed circuit element), and fire (the modules neither cause nor promote a fire). The present safety standards (IEC 61730 and UL 1703) do a good job of providing for design rules and test requirements for mechanical, shock, and spread of flame dangers. However, neither standard addresses the issue of electrical arcing within a module that can cause a fire. To make PV modules, they must be designed, built, and installed with an emphasis on minimizing the potential for open circuits and ground faults. This paper provides recommendations on redundant connection designs, robust mounting methods, and changes to the safety standards to yield safer PV modules. [ABSTRACT FROM PUBLISHER]

We study the vector-vector interaction within the framework of the hidden gauge formalism for the sector with quantum numbers charm C = 0 and strangeness S = 0 in the region around 4000 MeV. We get five poles, three of which could be identified with the Y(3940), Z(3930) and X(4160). These poles appear with quantum numbers I = 0 and JPC = 0++, 2++ and 2++, respectively, and can be considered as hadronic molecules made of D* D*,Ds* Ds* [ABSTRACT FROM AUTHOR]

We provide a discussion of the density and photoexcitation sensitivity of the X-ray spectra of Fe L-shell ions (Fe XVII–Fe XXIV) calculated with the Livermore X-ray Spectral Synthesizer, a suite of IDL codes that calculates spectral models of highly charged ions based primarily on HULLAC atomic data. These models are applicable to collisionally ionized laboratory or cosmic plasmas with electron temperatures Te ≈ 2–45 MK (0.2–4 keV) and electron densities ne >= 1011 cm-3. Potentially useful density diagnostics are identified for Fe XVII and Fe XIX–Fe XXIII, with the most straightforward being the Fe XVII I(17.10 Å)/I(17.05 Å) line ratio and the Fe XXII I(11.92 Å)/I(11.77 Å) line ratio. Applying these models to the Chandra X-ray Observatory High Energy Transmission Grating spectrum of the intermediate polar EX Hya, we find that the strength of all the Fe L-shell lines are consistent with electron densities ne >= 1 × 1014 cm-3. Specifically, from the observed Fe XVII I(17.10 Å)/I(17.05 Å) line ratio, we infer an electron density n e >= 2 × 1014 cm-3 at the 3 σ level, while from the observed Fe XXII I(11.92 Å)/I(11.77 Å) line ratio, we infer ne = 1.0-0.5+2.0 × 1014 cm-3 at the 1 σ level and ne >= 2 × 1013 cm-3 at the 3 σ level. © 2005 American Institute of Physics [ABSTRACT FROM AUTHOR]
