Distal Interphalangeal Joint Arthrodesis Complicated by Postoperative Infection: A Rare Presentation of Disseminated Herpes Simplex Virus.

Postoperative infection after elective arthrodesis of the interphalangeal joint is an uncommon complication often necessitating urgent debridement. We present the rare case of a female patient with a history of oral herpetic lesions, who underwent elective arthrodesis of the middle and index fingers for treatment of erosive osteoarthritis and subsequently developed a postoperative herpetic infection at the surgical site

LIMO EEG: A Toolbox for hierarchical LInear MOdeling of ElectroEncephaloGraphic data

Magnetic- and electric-evoked brain responses have traditionally been analyzed by comparing the peaks or mean amplitudes of signals from selected channels and averaged across trials. More recently, tools have been developed to investigate single trial response variability (e.g., EEGLAB) and to test differences between averaged evoked responses over the entire scalp and time dimensions (e.g., SPM, Fieldtrip). LIMO EEG is a Matlab toolbox (EEGLAB compatible) to analyse evoked responses over all space and time dimensions, while accounting for single trial variability using a simple hierarchical linear modelling of the data. In addition, LIMO EEG provides robust parametric tests, therefore providing a new and complementary tool in the analysis of neural evoked responses

The Matlab Vectorization Paradigm

We give two examples of application of a vectorized programming paradigm: binary addition and cycle decomposition of directed graphs

Optimization of toolpath trajectories on arbitrary surfaces

Given an arbitrary region on the plane, modelled as a graph with a symmetry, we describe a procedure to find the best orientation for slicing, via a zigzag tool-path trajectory based curve, in order to minimize its discontinuities. We also develop some directions on how to generalize the procedure up to the level of optimizing tool-path trajectories on arbitrary surfaces rather than planar regions only

Finite orbit decomposition of endomaps

In this work we present a vectorized Matlab algorithm for the decomposition of an endomap into its finite orbits

Computer tool for maximizing the placement of congruent polyhedra

Given multiple identical polyhedral objects and a parallelepiped container, how should one place the objects so that the largest number fits inside the container? This simple question is important in many applications, yet the answer is elusive. In fact, we know of no published solution for this very general formulation. Still, in many circumstances, further restrictions apply, resulting in a large number of variations requiring different algorithmic strategies. This paper is the continuation of [12] and focus on the fundamental concepts and tools that are used for this kind of problem, such as the no-fit polygon. We also present some of its many variations, giving in particular one that applies to the stereolithographic rapid prototyping technology

Computer construction of platonic solids

In this paper we develop a novel method to generate a 3D geometrical model from 2D planer images. As an example of application, we construct 3D models of each one of the five platonic solids from their platonic graphs

Assessing the mixing performance of extruders: indices and scale-up

This work proposes the use of global quantitative dispersive and distributive mixing indices to characterize the performance of a given screw. Calculation of these quantities uses a model of morphology evolution as a function of material and flow characteristics, which was coupled to a description of the flow developing along the screw from hopper to die. Scale-up on the basis of these indices is briefly discussed. Some results are presented in order to illustrate the usefulness of the methodology

The use of global mixing indices to assess mixing efficiency in single screw extrusion

Mixing indices can be derived from descriptions of morphology evolution of liquid-liquid or solid-liquid systems coupled to computations of flow and temperature along a plasticating screw (thus, including in the analysis the melting and melt conveying stages). In the case of liquid-liquid systems, distributive mixing depends essentially on droplet stretching and residence time, while dispersion takes into account the opposed effects of drop break-up and coalescence. Distributive mixing of solids-liquid systems depends on residence time and location (calculated via entropy), while dispersive mixing considers rupture and erosion phenomena
