Predicate encryption is an advanced form of public-key encryption that yield high flexibility in terms of access control. In the literature, many predicate encryption schemes have been proposed such as fuzzy-IBE, KP-ABE, CPABE, (doubly) spatial encryption (DSE), and ABE for arithmetic span programs. In this paper, we study relations among them and show that some of them are in fact equivalent b...

It is essential to estimate concentrations of unbound drugs inside the hepatocytes to predict hepatic clearance, efficacy, and toxicity of the drugs. The present study was undertaken to compare predictability of the unbound hepatocyte-to-medium concentration ratios (Kp,uu) by two methods based on the steady-state cell-to-medium total concentration ratios at 37°C and on ice (Kp,uu,ss) and based ...

Attribute-based encryption (ABE), as introduced by Sahai and Waters, allows for fine-grained access control on encrypted data. In its key-policy flavor, the primitive enables senders to encrypt messages under a set of attributes and private keys are associated with access structures that specify which ciphertexts the key holder will be allowed to decrypt. In most ABE systems, the ciphertext siz...

We present a novel derivative-based parameter identification method to improve the precision at the tool center point of an industrial manipulator. The tool center point is directly considered in the optimization as part of the problem formulation as a key performance indicator. Additionally, our proposed method takes collision avoidance as special nonlinear constraints into account and is ther...

Assessing the testing or software development process by only using KPIs can easily be misleading. A better solution is a paradigm shift to value-based software engineering, which integrates value considerations into software engineering and offers a broader and more technical view on KPIs. Coverage metrics are such a technical view and a very helpful KPI. This paper combines value-based testin...

BACKGROUND Children with attention deficit-hyperactivity disorder (ADHD) often experience delays in acquiring competence completing fundamental motor skills. The effects of augmented prescriptive knowledge of performance feedback (PKP) have not been explored as a possible component solution. AIMS The purpose of this study was to test the motor learning effects of KP among boys with ADHD. ME...
