OBJECTIVE Describe the results from arthroscopic surgical treatment on a group of patients who developed symptoms after repetitive physical activity of moving their hips in a position of hyperflexion, as in leg presses and squats. METHODS The study group comprised 47 individuals (48 hips) who developed the onset of painful symptoms associated with hip hyperflexion exercises (leg presses or sq...

The brain activity during cooperation as a form of social process is studied. We investigate the relationship between coinstantaneous brain-activation signals of multiple participants and their cooperative-task performance. A wearable near-infrared spectroscopy (NIRS) system is used for simultaneously measuring the brain activities of two participants. Each pair of participants perform a cooper...

The synaptic Ras/Rap-GTPase-activating protein (SynGAP) regulates specific intracellular events following N-methyl-d-aspartate receptor (NMDAR) activation. Here, the impact of SynGAP heterozygous knockout (SG+/-) on NMDAR-dependent functions was assessed using different positive reinforcement schedules in instrumental conditioning. The knockout did not affect the temporal control of operant res...

We outline the work of two university presses, with assistance from Community-led Publishing Infrastructures for Monographs (COPIM) Project, in creating an innovative revenue model to fund Open Access (OA) monographs at a traditional publisher. Building on library journal subscription models and Knowledge Unlatched's approach monograph funding, this OA publishing (called “Opening Future”) gives...

The use of human fingers as an object selection and manipulation tool has raised significant challenges when interacting with direct-touch tabletop displays. This is particularly an issue when manipulating remote objects in 3D environments as finger presses can obscure objects at a distance that are rendered very small. Techniques to support remote manipulation either provide absolute mappings ...

The first part of this paper describes the editorial decisions that led to the publishing of The Skeptical Environmentalist (TSE) and the rejection of requests by critics that Cambridge should cease publication on the grounds of claims that it had not been peer-reviewed and that it would be abused by right wing political interests seeking justification for opposing new environmental regulation....

This paper presents a method of integrating two contrasting sensor systems for studying human interaction with a mechanical system, using piano performance as the case study. Piano technique requires both precise small-scale motion of fingers on the key surfaces and planned large-scale movement of the hands and arms. Where studies of performance often focus on one of these scales in isolation, ...

The movable type printing press was the great innovation in early modern information technology, but economists have found no evidence of its impact in measures of aggregate productivity or income per person. This paper examines the technology from a new perspective by exploiting city-level data on the establishment of printing presses in 15th century Europe. I find that between 1500 and 1600, ...

Grasping analysis is concerned with relating the characteristics of the grasped object to the requirements of the gripper structure. When a gripper presses a flexible specimen with a size larger than that of the gripping surface, complex deformations are produced (compression, shearing, bending and tension). The boundary conditions are complex too because of the changing compressed region and, ...

The manufacture of bi-layer tablets, produced by the sequential compaction of loose powder layers has recently become of increased interest within the pharmaceutical industry due to the tailored release profiles of active ingredients that may be obtained. In a bi-layer configuration, the immediate release layer of the bilayer tablet has worked as the loading dose and the sustained release layer...
