Recently, a concept of digital metamaterials has been proposed to manipulate field distribution through proper spatial mixtures of digital metamaterial bits. Here, we present a design of 2-bit digitally-controlled coding metasurface that can effectively modulate the scattered electromagnetic wave and realize different far-field beams. Each meta-atom of this metasurface integrates two pin diodes...

Two or more Bayesian Networks are Markov equivalent when their corresponding acyclic digraphs encode the same set of conditional independence (≡ CI) restrictions. Therefore, the search space of Bayesian Networks may be organized in classes of equivalence, where each of them consists of a particular set of CI restrictions. The collection of sets of CI restrictions obeys a partial order, the grap...

The title complex, [Mn(2)(C(8)H(7)O(3))(4)(C(12)H(8)N(2))(2)]·0.5CH(3)OH, is a carboxyl-ate-bridged dinuclear Mn(II) complex with four phenoxy-acetate ions and two 1,10-phenanthroline mol-ecules as ligands. Each of the four phenoxy-acetate anions bridges the pair of Mn atoms. The asymmetric unit is completed by a half-occupancy methanol solvent mol-ecule. Face-to-face π-π stacking inter-actions...

OBJECTIVE To identify the physiological and anthropometric determinants of sport climbing performance. METHODS Forty four climbers (24 men, 20 women) of various skill levels (self reported rating 5.6-5.13c on the Yosemite decimal scale) and years of experience (0.10-44 years) served as subjects. They climbed two routes on separate days to assess climbing performance. The routes (11 and 30 m i...

The Internet is rapidly transforming a range of human activities; socio-cognitive theory assumes that engagement in transformed activities, over time, transforms human cognition. Four hundred and six college students completed four modified cognitive assessment system subtests, each assessing one dimension of the PASS model of cognitive processing (i.e., planning, attention, simultaneous and su...

We examined the relationships of perceived organizational support and job satisfaction with organizational citizenship behavior and task performance in China. Employees from two large-scale state-owned enterprises (SOE) completed measures of perceived organizational support and job satisfaction and their immediate supervisors completed measures of task performance and four facets of organizatio...

The interest in adventure sports, particularly high-altitude hiking and climbing, is on the rise and there are hundreds of thousands of fans worldwide. As a result, there is also considerable interest from the public health and economic points of view in the diagnosis of cardiopulmonary complications inherent to these sports, which mainly occur secondary to pulmonary hypertension (PHT) caused b...
