Quantum measurements based on mutually unbiased base (MUB) are commonly used in quantum information processing. Firstly, we construct two completed unextendible maximally entangled bases (UMEBs) in bipartite systems [Formula: see text]. Then, the sufficient and necessary conditions of these two UMEBs develop into MUB can be obtained. Finally, we present some UMEBs that are mutually unbiased in concrete bipartite systems. These results provide a method to construct the best measurement bases.

In this paper, we derive key-rate expressions for different quantum key distribution protocols. Our key-rate equations utilize multiple channel statistics, including those gathered from mismatched measurement bases - i.e., when Alice and Bob choose incompatible bases. In particular, we will consider an Extended B92 and a two-way semi-quantum protocol. For both these protocols, we demonstrate that their tolerance to noise is higher than previously thought - in fact, we will show the semi-quantum protocol can actually tolerate the same noise level as the fully quantum BB84 protocol. Along the way, we will also consider an optimal QKD protocol for various quantum channels. Finally, all the key-rate expressions which we derive in this paper are applicable to any arbitrary, not necessarily symmetric, quantum channel.

Structure of the Observed Learning Outcome (SOLO) science superitems were examined from the perspectives of Guttman Scaling (deterministic) and Item Response Theory (probabilistic). Differences between the measurement bases for the two approaches, and the results for a small case study, are reported. In general, the analyses confirmed the hypothesised patterns of learners' responses, but also revealed some discrepancies in particular superitems that can be interpreted within the framework of the SOLO taxonomy.

In order to improve the accuracy of cable tension test, the motionequation of the stay cable with the rubber damper was established bases on the principleof Hamilton. First, the correction method for the damping coefficient of rubberdamper and cable tension was proposed according to the higher modal frequencyand measured frequency of cables difference. Then, take the cable of DongtingLake Bridge as an example, the cable tension was calculated by the proposedmethod and compared with the results of measurement by frequency method.Results showed that the proposed method can improve the accuracy of cabletension test and can effectively evaluate the cable tension condition of thecable-stayed bridge.

Measurement Bases

The IASB’s conceptual framework for financial reporting identifies multiple measurement bases and concludes that an entity may employ more than one measurement base in constructing the financial reports. The framework further clarify situations as to how the preparers will proceed in constructing the entity’s financial report where the preparers are satisfied that a piece of information is relevant to the users of financial reports, but is subject to a high degree of measurement uncertainty. The purpose of this paper is to critically evaluate the choice of multiple measurement bases in the conceptual framework and highlight the challenges posed to a user of financial reports who seeks to obtain insights into an entity’s financial performance and position through reading reports constructed using an eclectic approach to measurement.
