A 34-year-old man presented with tinnitus and conductive hearing loss. CT demonstrated an expansile, air-containing cavity contiguous with mastoid air cells, narrowing the external auditory canal. This is a case of symptomatic pneumocele resulting in an air collection beneath external canal lining, possibly related to an abnormality in mastoid fusion.

Purpose: The patellofemoral pain syndrome (PFPS) is one of the most common musculoskeletal disorders of the knee joint. Hip muscles’ weakness is one of the reasons for PFPS occurrence. The aim of this study was to recognize the effective muscle group in prevention and treatment of patients with PFPS. Methods: This is a prospective and quasi-experimental study in which 30 participants (15 ...

This paper presents the findings from a large-scale empirical investigation into the impact of external intervention into business process improvement using a hybrid model of knowledge transfer (KT). Through the utilization of a survey instrument with 696 respondents, the research explores the insights into a phased approached to sustainable external intervention. Analysis of the empirical data...

Multi-source, unstructured and external data analytics for manufacturing process Taehoon Ko Department of Industrial Engineering The Graduate School Seoul National University Data integration means the task of combining data with various types residing at different sources, and providing the user with a unified view of these data. In this thesis, we consider the data integration as the process ...

A critical aspect in the modeling of biological systems is the description view point. On the one hand, the Stochastic π-calculus formalism provides an intuitive and compact representation from an internal perspective. On the other hand, other proposed languages such as Hybrid Automata and Stochastic Concurrent Constraint Programming introduce in the system description an external control and p...

We analysed published force-velocity data for kinesin using classical Michaelis-Menten kinetic theory and found that the effect of force on the stepping rate of kinesin is analogous to the effect of a mixed inhibitor in classical inhibition theory. We derived an analytical expression for the velocity of kinesin (the stepping rate, equal to the ATP turnover rate) as a function of ATP concentrati...

One is interested here in the observation of dynamic processes starting from the traces which they leave or those that one makes them produce. It is considered here that it should be possible to make several observations simultaneously, using a large variety of independently developed analyzers. For this purpose, we introduce the original notion of ``full trace'' to capture the idea that a proc...

In this paper we present a powerful technique for analysing complex production systems incorporating task duration, cost, and the impact of external factors. Processes are modelled as a network, similar to PERT/CPM schemes, but with built-in decision and cost variables. For minimal increased complexity in the development of the network, we show that powerful analysis and optimisation techniques...

Prior research highlights the vital role of information technology (IT) for innovation in firms. In this paper, we draw on the knowledge-based view of the firm to investigate how search in external knowledge sources and information technology for knowledge absorption jointly influence process innovation performance. Our model is tested on a nineyear panel (2003–2011) of Swiss firms from a wide ...
