Quarterly Journal of the Royal Meteorological Society, EarlyView.Across the Maritime Continent, diurnal rainfall variability is governed by interactions between regional‐scale atmospheric drivers and local land–sea breeze circulations. Afternoon convection is initiated over land by surface heating and propagates offshore, whereas morning rainfall develops over adjacent seas and moves inland under low‐level northerly

Remote Sensing in Ecology and Conservation, EarlyView.We demonstrate that high‐resolution multispectral imagery combined with machine learning can accurately predict key biocrust functional indicators, particularly the UV‐protective pigment scytonemin, across dryland ecosystems. Using fine‐scale imagery acquired in the Chihuahuan Desert and Colorado Plateau, we identified spectral bands strongly ...

On double domination in graphs [PDF]
, 2005 In a graph G, a vertex dominates itself and its neighbors. A subset S ⊆ V (G) is a double dominating set of G if S dominates every vertex of G at least twice. The minimum cardinality of a double dominating set of G is the double domination number γ×2(G).

Concrete in architecture: Redefining form, space, function, and insights from bibliometric analysis
Structural Concrete, EarlyView.Abstract Concrete has become a cornerstone in architectural and engineering innovation, as it seamlessly integrates structural performance with artistic expression. Its evolution from ancient opus caementicium to contemporary ultra‐high‐performance concrete illustrates its adaptability to the change in technological, environmental, and design paradigms.

Simple and detailed modeling of corrosion‐affected slender shear critical RC beams
Structural Concrete, EarlyView.Abstract The corrosion of steel bars compromises both the safety and the serviceability of reinforced concrete (RC) structures. Consequently, reliable tools are required to estimate the detrimental effects of corrosion on the structural response of RC members subjected to transverse loads.

The study of Roman domination number
, 2015 碩士在一個圖G=(V,E)上， 定義一個函數 f 將V對應到{0, 1, 2}，假如f滿足每一個對應到0 的點都有一個對應到2的鄰居，函數 f 稱為羅馬控制函數。函數f的權重為圖中所有點相應的權重總和，而所有可能的羅馬控制函數中權重最小者稱為圖 G 的羅馬控制數。一個蜘蛛圖 G(k_1,k_2,k_3,…,k_t )為含有共同端點的t個路徑〖 P〗_(k_1 ), 〖 P〗_(k_2 ), …, 〖 P〗_(k_t )所形成的圖。一個一般蜘蛛圖〖 C〗_t (k_1,k_2,k_3,…,k_t ...

Roman Domination in Weighted Graphs
MathematicsA Roman dominating function for a (non-weighted) graph G=(V,E) is a function f:V→{0,1,2} such that every vertex u∈V with f(u)=0 has at least one neighbor v∈V such that f(v)=2.

Acta Crystallographica Section C, EarlyView.The solvent‐free structure of the thallium(I) salt of the weakly coordinating anion tetrakis[3,5‐bis(trifluoromethyl)phenyl]borate, Tl[BC32H12F24], exhibits short Tl…F contacts and a supramolecular architecture governed by C—H…F hydrogen bonds and weak F…F and C—F…π interactions.
