ABSTRACTOpen innovation (OI) is an effective way for small and medium-sized enterprises (SMEs) to acquire external resources enhance performance. This study focuses on the effect of OI performance SMEs. Specifically, this classifies into inbound outbound OI, explores their respective impacts SMEs' Besides, investigates mediating role absorptive capacity moderating business model above relationships. Based survey data from 218 Chinese manufacturing SMEs, our empirical results show that: (1)...

Abstract Photodegradation is considered as a universal contributing factor to litter decomposition and carbon (C) cycling within the Earth’s biomes. Identifying how solar radiation modifies molecular structure of essential understand mechanism controlling its reaction shifts in climatic conditions land-use. In this study, we performed spectral-attenuation experiment following an understory gap temperate deciduous forest. We found that short-wavelength visible light, especially blue was main...

Sweetpotato (Ipomoea batatas (L.) Lam.) is a genetically intricate hexaploid crop. The purple-fleshed variety, enriched with anthocyanin pigments, an outstanding source for creating high-value functional products. Previous research on biosynthesis has primarily focused the above-ground plant parts at transcriptional level. However, regulatory mechanisms underlying accumulation in underground tuberous roots of sweetpotato remain largely unexplored. This study aimed to elucidate...

A linear systolic array for the discrete cosine transform, sine and their inverses is developed. It generates transform kernel values recursively. Compared to scheme with prestored in memory either inside or outside each processing element, clock period shortened by a access time. In addition, pays no cost prestorage. The has advantages of pipelinability, regularity, locality, scalability, making it quite suitable VLSI signal processing.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML"...

Abstract A firm’s participation in an innovation ecosystem can increase its competitiveness and potentiality turbulent circumstances. From a resource-based view (RBV) the value proposition perspective, this study explored how heterogeneous ecosystems affects innovative performances (IPs) of start-ups. We studied adaptability between models open (OI) strategies, as well examined their effects on new ventures. Specifically, were classified into platform- product-based according to structural...

Recently, R.N. Bracewell (1983) introduced the discrete Hartley transform (DHT) as an alternative to Fourier (DFT). Two linear systolic array models for are derived. One model requires O(2N-1) in computational phase and O(N) preloading phase. The other output A square two-dimensional DHT is also constructed by combining individual advantages of each model. CORDIC algorithm proposed conventional multipliers. To speed up array, two-level pipelining with possible.< <ETX...

A bit-level systolic array for median filters based on the majority of bit strings input samples is presented. The function can be implemented by a 1-b odd/even transposition network, which regular and designed easily. If each sample represented r bits, contains processor elements requires time complexity O(N+n+r-1) stream N with window size n in one-dimensional filter.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
