We develop a model of international trade with export quality requirements and two dimensions of firm heterogeneity. In addition to " productivity " , firms are also heterogeneous in their " caliber " – the ability to produce quality using fewer fixed inputs. Compared to single-attribute models of firm heterogeneity emphasizing either productivity or the(More)
Light emitting diodes (LEDs) can be used as light detectors and as light emitters. In this paper, we present a novel BRDF measurement device consisting exclusively of LEDs. Our design can acquire BRDFs over a full hemisphere, or even a full sphere (for the bidirectional transmittance distribution function BTDF), and can also measure a (partial)(More)
A high performance table-based architecture implementation for CRC (cyclic redundancy check) algorithms is proposed. The architecture is designed based on a highly parallel CRC algorithm. The algorithm first divides a given message with any length into bytes. Then it performs CRC computation using lookup tables among the divided bytes in parallel. At last,(More)
The molecular pathway regulating gastric carcinoma (GC) invasiveness and metastasis remains elusive. Here, we detected significant increase in the phosphorylated epidermal growth factor receptor (pEGFR), MMP7, and MMP13 in the resected GC, compared with the adjacent normal tissue, in patients. Moreover, strong positive correlation was detected between pEGFR(More)
In this paper, a method for through-wall human detection based on the singular values decomposition of the measurement matrices is presented. After demonstrating the sparsity of the matrices using CLEAN algorithm, an SVD algorithm based on Lanczos process is applied to compute their singular values. We also analyze the singular values of matrices(More)
Edge detection is one of the key stages of image processing and object recognition. Canny edge detector is the most widely used edge detection algorithm because of its good performance. In this paper, a hardware architecture for real-time Canny edge detection has been proposed. By adopting the improved median filter, the performance and reliability of the(More)
Recent evidence suggests that the association between oxytocin receptor polymorphism (OXTR rs53576) and emotion-related behavioral/psychological tendencies differs between individuals from East Asian and Western cultures. What remains unresolved is which specific dimension of cultural orientations interacts with OXTR rs53576 to shape these tendencies and(More)
