Structural and stratigraphic discontinuities, such as faults and channels, generally contribute to the construction of traps and reservoirs. Spectral decomposition can utilize the sensitivities of different frequency components to different geological conditions to identify these geological anomalies. The sparse inverse spectral decomposition (SISD) involves a sparse constraint of time–frequency spectra, and one critical parameter is the sparsity which determines the time–frequency resolution. A small sparsity gives a low temporal resolution result that cannot be used for thin-bed detection. Conversely, a large sparsity provides a high-resolution result, but it may lose weak refection signals. The complex geological conditions in the subsurface will lead to some difficulties in detecting the discontinuities by using the SISD method with a fixed sparsity. To address this issue, we propose multi-sparsity-based spectral attributes by fusing the amplitude spectra results of three different sparsities to detect subsurface discontinuities. Compared with the fixed sparsity, the multi-sparsity-based spectral attributes can detect more geological details and highlight geological edges more clearly. The application on a 3D real data with an area of 230 km2 from deep formation in Northwest China exhibits its effectiveness in discontinuity detection. The proposed method can detect the weak or small hidden geological details more and better than the fixed sparsity method, suggesting that it may serve as a future tool for detecting the distribution of geological abnormalities in subsurface.

Dzieło architektoniczne przyrównać można do dzieła literackiego. Można próbować analizować go jako fabułę, opowieść zapisaną językiem formy architektonicznej, w kontekście pięciu najbardziej cenionych przez I. Calvino cech dzieła literackiego (lekkości, dokładności, szybkości, przejrzystości i wielorakości). Zakłada się, ze dzieło architektoniczne musi spełniać kryteria witruwiańskiej triady, gdy inaczej nie mogłoby być za takie uznane. Przeanalizowano dwa przykłady współczesnych realizacji budowli sakralnych Krakowa, jako posiadające wszystkie, charakterystyczne dla obu ujęć cechy.

Architectural masterpiece is similar to literature masterpiece. Both might be subject to the analysis in Vitruvian context of durability, suitability, beauty (firmitas, utilitas, venustas) and Calvino's context of lightness, accuracy, speed, transparency and diversity. A building to be recognized as an architectural masterpiece must fulfill vitruvian features first. Two of the contemporary churches in Cracow were analyzed, as compatible with all three Vitruvius' and five Calvino's features.

Transparency is one of physical esthetic categories that are used to describe literature and other arts. The main aim of this paper is to show how those esthetic categories are used on three levels: esthetic, performatively dramatic and philosophical in modern literature, theater, film and fine arts. The starting point for those considerations are methods of Italo Calvino (“American lectures”) and Marek Bieńczyk (his collection of essays titled “Transparency”) . Calvino’s category of “transparency” (in his attempt to go beyond anthropocentric cognition with the author’s main question: “Is imagination an instrument of cognition?”) is contrasted with Marek Bieńczyk’s term of “transparency”, who has pointed out the positive aspects of paintings (which are not only giving a feeling of emptiness but also provide certainty of clarity and obviousness). In addition to these categories, lucidity and glassiness are featured and a crystal structure is summoned in the context of mistiness as its opposition.
