The weld seam detection method based on the infocrnet model

Weld seam detection is particularly crucial within industrial systems, as it promptly reflects the quality of product fabrication and performance, ensuring the final metallurgical product’s quality while mitigating potential losses stemming from product quality issues. This paper proposed the InfoFPN Cross Refinement Network (InfoCRNet) for the weld seam detection, achieving an accuracy rate of 98,90% and F1 score of 98,85 %

Cloning and characterization of a putative transcription factor induced by abiotic stress in Zea mays

bZIP transcription factors have been reported to play important roles in plant responses to abiotic stresses. Here, we reported the cloning and characterization of a putative bZIP transcription factor (ZmbZIP17) from maize inbred line Han21, which is up-regulated by drought treatment. The open reading frame sequence of ZmbZIP17 was obtained by using 5’RACE and RT-PCR. Sequence analysis showed that ZmbZIP17 encodes a polypeptide of 563 amino acids with predicted molecular mass of59.8 kDa and pI of 5.6. Southern blot analysis showed that ZmbZIP17 exists as a single copy gene in maize genome. Subcellular localization of ZmbZIP17 was identified in nucleus. The results of real-time PCR analysis indicated that ZmbZIP17 was up-regulated by drought, heat, ABA and NaCl stressimmediately, which suggested that ZmbZIP17 is an early stage responsive gene to various abiotic stresses. The result also showed that ZmbZIP17 expressed much higher in leaves than in other organs in maize seedlings

Quantum Group as Semi-infinite Cohomology

We obtain the quantum group $SL_q(2)$ as semi-infinite cohomology of the Virasoro algebra with values in a tensor product of two braided vertex operator algebras with complementary central charges $c+\bar{c}=26$. Each braided VOA is constructed from the free Fock space realization of the Virasoro algebra with an additional q-deformed harmonic oscillator degree of freedom. The braided VOA structure arises from the theory of local systems over configuration spaces and it yields an associative algebra structure on the cohomology. We explicitly provide the four cohomology classes that serve as the generators of $SL_q(2)$ and verify their relations. We also discuss the possible extensions of our construction and its connection to the Liouville model and minimal string theory.Comment: 50 pages, 7 figures, minor revisions, typos corrected, Communications in Mathematical Physics, in pres

Extraction of Black Hole Geometry in Exactly Quantized Two Dimensional Dilaton Gravity

Based on our previous work, in which a model of two dimensional dilaton gravity of the type proposed by Callan, Giddings, Harvey and Strominger was rigorously quantized, we explicitly demonstrate how one can extract space-time geometry in exactly solvable theory of quantum gravity. In particular, we have been able to produce a prototypical configuration in which a ( smeared ) matter shock wave generates a black hole without naked sigularity.Comment: LATEX file 10 pages.
