BACKGROUND Global postural re-education (GPR) has shown positive results for patients with musculoskeletal disorders, but no previous randomized controlled trial (RCT) has investigated its effectiveness as the sole procedure for adult patients with chronic nonspecific neck pain (NP). OBJECTIVE The purpose of this study was to evaluate the effectiveness of applying GPR compared with a manual t...

Englacial horizons deeper than 100m are absent within 100MHz ground-penetrating radar (GPR) surface profiles we recorded on Clark and Commonwealth Glaciers in the Antarctic Dry Valleys region. Both glaciers show continuous bottom horizons to 280m, with bottom signal-to-noise ratios near 30 dB. Density horizons should fade below 50m depth because impermeable ice occurred by 36m. Folding within C...

Cytokinesis and spindle positioning require the cortical force regulator G Protein Regulator 1/2 (GPR-1/2). GPR-1/2 is thought to localize to sites of cortical force generation. Does GPR-1/2 also act as a sensor for mechanical stimulation? I mechanically stimulated the cortex by indenting it with a glass needle and observed the cortical localization of a YFP::GPR-1 transgene. I found that corti...

The application of Ground Penetrating Radar (GPR) prospecting to the search fossil structures, particularly using advanced techniques like Finite-difference time-domain (FDTD) modelling and GPR attribute analysis, is currently poorly exploited in paleontology. Here, we promote use such a workflow at Bargiano (Umbria, central Italy), unique paleontological site known for discovery cetacean skele...

Dating back to as far as 1940, the US road and bridge infrastructure system has garnered quite the status for strategically connecting together half a continent. As monumental as the infrastructure’s status, is its rate of deterioration, with the average bridge age coming at a disconcerting 50 years. Aside from visual inspection, a battery of non-destructive tests were developed to conduct stru...

The objective of this study was to evaluate the quality of life (QL) with the use of the SF-36 Questionnaire in patients with chronic nonspecific low back pain (CNLBP). Thirty patients with CNLBP were randomly assigned to one of three groups (Iso group (Isostretching), GPR group (Global Postural Reeducation), and the Iso+GPR group. Patients underwent physical therapy assessment with the use of ...

The shape and feature extraction in Ground Penetrating Radar (GPR) data is the most addressed application in present underground object identification technique. The problem of automatically detecting the shape and feature in GPR data is in analysing and fitting the hyperbola features from GPR data objects. To address these, we propose a hyperbole fitting method to extract the shape and feature...

Ground-penetrating radar (GPR) is capable to detect plastic antipersonnel landmines as well as other subsurface targets. In order to reduce false alarms, an option of automatic landmine discrimination from neutral minelike targets would be very useful. This paper presents a possibility for such discrimination and analyzes it experimentally. The authors investigate time–frequency features of an ...

Ground penetrating radar (GPR) has emerged as an effective tool for estimating active layer thickness (ALT) and volumetric water content (VWC) within the active layer. In August 2013, we conducted a series of GPR and probing surveys using a 500 MHz antenna and metallic probe around Barrow, Alaska. We collected about 15 km of GPR data and 1.5 km of probing data. Here, we describe the GPR data pr...

Full waveform inversion (FWI) of seismic or Ground Penetrating Radar data provides high-resolution quantitative images of the constitutive parameters of the rock/soil which control seismic/GPR wave propagation. We developed a 2D inversion tool in the frequency domain adapted to the multi-parameter physics controlling GPR propagation in isotropic non dispersive media, i.e. dielectric permittivit...
