A numerical method to solve the Stokes problem with a punctual force in source term
The aim of this note is to present a numerical method to solve the Stokes
problem in a bounded domain with a Dirac source term, which preserves
optimality for any approximation order by the finite-element method. It is
based on the knowledge of a fundamental solution to the associated operator
over the whole space. This method is motivated by the modeling of the movement
of active thin structures in a viscous fluid.Comment: Comptes Rendus M{\'e}canique, Elsevier, 2015,

CREOLE: a Universal Language for Creating, Requesting, Updating and Deleting Resources
In the context of Service-Oriented Computing, applications can be developed
following the REST (Representation State Transfer) architectural style. This
style corresponds to a resource-oriented model, where resources are manipulated
via CRUD (Create, Request, Update, Delete) interfaces. The diversity of CRUD
languages due to the absence of a standard leads to composition problems
related to adaptation, integration and coordination of services. To overcome
these problems, we propose a pivot architecture built around a universal
language to manipulate resources, called CREOLE, a CRUD Language for Resource
Edition. In this architecture, scripts written in existing CRUD languages, like
SQL, are compiled into Creole and then executed over different CRUD interfaces.
After stating the requirements for a universal language for manipulating
resources, we formally describe the language and informally motivate its
definition with respect to the requirements. We then concretely show how the
architecture solves adaptation, integration and coordination problems in the
case of photo management in Flickr and Picasa, two well-known service-oriented
applications. Finally, we propose a roadmap for future work.Comment: In Proceedings FOCLASA 2010, arXiv:1007.499
Pre-Operative Outpatient Physical Therapy Of A Torn Rotator Cuff And Suspected Nerve Injury Caused By Anterior Shoulder Dislocation: A Case Report
Background and purpose: Rotator cuff repair surgeries are very common and there are many different post-operative rehabilitation protocols available, but there is little to no literature on pre-operative therapy. The purpose of this case report is to investigate the effectiveness of pre-operative passive range of motion (ROM), joint mobilization and exercises for a patient with both a torn rotator cuff and a suspected neuropraxic peripheral nerve injury. Case Description: The patient was a healthy 47-year-old male with no prior medical or surgical history. He was referred to outpatient physical therapy for pre-operative joint mobilization and exercise for his left shoulder, which he anteriorly dislocated in a snowboarding accident. He also reported progressive loss of function and sensation in his left distal upper extremity (UE), which began 1-2 days after his accident. He was seen for four physical therapy sessions including the initial evaluation prior to undergoing rotator cuff surgery. Outcomes: The patient reported decreased pain, and improved sensation and demonstrated improved motor control of his left distal UE; but showed little measurable improvement in the QuickDASH functional outcome measure during the short time before his rotator cuff surgery. Discussion: Although the patient was only seen for a short period of time, and demonstrated little improvements on the QuickDASH, pre-operative physical therapy may still be effective for rotator cuff repairs. The patient reported decreased pain levels and improved motor control and sensation of his left distal UE. He also reported feeling less anxious about his surgery and better prepared for post-operative rehabilitation
Pre-Operative Outpatient Physical Therapy Of A Torn Rotator Cuff And Peripheral Nerve Injury Caused By Anterior Shoulder Dislocation: A Case Report
Background: Due to the high degree of available range of motion of the Glenohumeral joint, it is highly susceptible to instability and injury. 98% of all traumatic shoulder dislocations are anterior. Rotator cuff injuries and peripheral nerve injuries are commonly associated with traumatic anterior shoulder dislocations. Very little literature exists on pre-operative PT. Purpose: To investigate the effectiveness of pre-operative physical therapy (PT) management including passive range of motion, joint mobilization and exercises for a patient with both a torn rotator cuff and suspected neuropraxic peripheral nerve injury.https://dune.une.edu/pt_studcrposter/1006/thumbnail.jp
Absolute identification by relative judgment
In unidimensional absolute identification tasks, participants identify stimuli that vary along a single dimension. Performance is surprisingly poor compared with discrimination of the same stimuli. Existing models assume that identification is achieved using long-term representations of absolute magnitudes. The authors propose an alternative relative judgment model (RJM) in which the elemental perceptual units are representations of the differences between current and previous stimuli. These differences are used, together with the previous feedback, to respond. Without using long-term representations of absolute magnitudes, the RJM accounts for (a) information transmission limits, (b) bowed serial position effects, and (c) sequential effects, where responses are biased toward immediately preceding stimuli but away from more distant stimuli (assimilation and contrast)
