Soft x-ray magnetic circular dichroism was used to study a paramagnetic bioinogranic system. We measured the Fe L edges of Pyrococcus furiosus rubredoxin, using circularly polarized synchrotron radiation, a split-coil super-conducting magnet, low sample temperatures, and fluorescence detection. The observed dichroism effect is strong (30%) and in general agreement with the calculation. The meth...

Extremely compact high repetition rate soft X-ray lasers based on capillary discharge excitation have demonstrated average powers of a few milliWatt at 46.9 nm, milli-Joule-level pulse energy, peak spectral brightness several orders of magnitude larger than third-generation synchrotron beam lines, and excellent spatial coherence. Examples of the use of a capillary discharge soft X-ray laser in ...

The use of platelet-rich plasma (PRP) to improve clinical outcome following a soft tissue injury, regeneration, and repair has been the subject of intense investigation and discussion. This article endeavors to relate clinical and basic science strategies focused on biological augmentation of the healing response in anterior cruciate ligament (ACL) and meniscus repair and replacement using PRP....

We present the first experimental demonstration of lensless diffractive imaging using coherent soft x rays generated by a tabletop soft-x-ray source. A 29 nm high harmonic beam illuminates an object, and the subsequent diffraction is collected on an x-ray CCD camera. High dynamic range diffraction patterns are obtained by taking multiple exposures while blocking small-angle diffraction using be...

This paper reports on an innovative combination of hard and soft methods – soft systems methodology and data envelopment analysis – in a project evaluating the performance of the basic research institutes of the Chinese Academy of Science. Problems in defining and agreeing appropriate inputs and outputs for DEA led to the use of SSM as a way or producing a comprehensive and systemic database of...

By discovering predictive relationships between different pieces of extracted data, data-mining algorithms can be used to improve the accuracy of information extraction. However, textual variation due to typos, abbreviations, and other sources can prevent the productive discovery and utilization of hard-matching rules. Recent methods for inducing softmatching rules from extracted data can more ...

the application of laser in dentistry is considered as a favorable technique for patients due to its many advantages compare to other current methods. one of the main goals in pediatric dentistry is to provide the treatment as comfortable as possible without any risks for the care. laser is being used in different pediatric dental conditions including caries detection, caries removal and cavity...

hereby we report a case of well-differentiated intraosseous osteosarcoma in the sacrum. a 32-year-old woman was admitted to our hospital with a low echo-level mass in the pelvis searched by ultrasound in a routine physical examination. radiographically, the mass was misdiagnosed as a benign bony tumor originating from the sacrum. the tumor was completely resected and pathological diagnosis was ...

this paper presents four cases of abnormal soft tissue activity in the bone scan of patients with different lesions (lung inflammatory pseudotumor, pulmonary fibrosis, pulmonary metastatic osteosarcoma and metastatic hepatic carcinoma of colon).

injection of synthetic fillers for soft tissue augmentation is increasing over the last decade. one of the most common materials used is hyaluronic acid (ha) that is safe and temporary filler for soft tissue augmentation. we present a case of 54-year-old female who experienced vascular occlusion and nasal alar necrosis following ha injection to the nasolabial folds. she suffered from pain, necr...
