All-fiber magnetic-field sensor based on a device consisting of microfiber knot resonator and magnetic fluid is proposed for the first time in this Letter. Sensor principles package technology are introduced detail. Experimental results show that resonance wavelength regularly varies with changes to applied field. When field increased 600 Oe, shift reaches nearly 100 pm. Moreover, responding 50 Hz alternating also experimentally investigated, minimal detectable strength 10 Oe successfully achieved.
Radiofrequency ablation (RFA) is now a widely used minimally invasive treatment method for hepatic tumors. Preoperative planning plays vital role in RFA therapy. With increasing tumor size, multiple overlapping ablations are needed, which challenging to optimize while considering clinical constraints. In this paper, we present new automatic method. First, 2-steps set cover-based model formulated, can integrate constraints optimization of ablations. To ensure that the be solved reasonable...
An evanescent field-based microfiber knot resonator (MKR) refractive index sensor with long-term stability was proposed in this letter. To protect the from mechanical and optical degradation at same time preserve large waves, a dip-coating technique presented to coat MKR thin coating submicrometer thickness range experimentally fabricated. The temporal of coated its sensing properties were, respectively, investigated. results indicated that did not degrade over long time, minimal detectable...
We demonstrate a novel compact optical magnetic field sensor composed of single-mode microfiber sagnac loop interferometer (SMSLI) and ferrofluid (FF). The refractive index FF cladding in the twist area SMSLI is changed with externally applied field, which makes dip-wavelength transmission spectra shift. experimental results show that spectrum proposed shifts regularly change intensity. When intensity increased from 0 to 600 Oe, shifted nearly 200 pm. In addition, minimal detectable strength...
With rapid globalization and the increasing demand for traditional Chinese medicines, quality safety has become a critical priority both domestic international markets. However, medicines are susceptible to contamination by pathogenic microorganisms during process of cultivation, growth, processing, storage, transportation, which can lead mycotoxin that adversely affect may pose potential threats human health. This review summarizes contamination, common detection methods, prevention control...
Joint line (JL) is a very important factor for total knee arthroplasty (TKA) to restore. The objective of this study was evaluate the early clinical and kinematic results TKAs with posterior-stabilized (PS) or cruciate retaining (CR) implants in which JL elevated postoperatively.Data were collected from patients who underwent TKA our department between April 2011 2014. divided into two groups based on prosthesis they received (PS CR). At 1-year postoperatively, outcomes evaluated by American...
Approaches to controlling C=N facial selectivity in allylic addition imino compounds are reviewed. Stereocontrol methods involving chiral substrates, auxiliaries, reagents, and catalysts discussed the context of recent examples.
The wire fixation and the cable grip have been developed for extended trochanteric osteotomy (ETO) in revision of total hip arthroplasty (THA). Many studies reported postoperative performance patients, but with little quantitative biomechanical comparison two systems.An in-vitro testing approach was designed to record loosening between femoral bed greater trochanter after fixations. Ten cadaveric femurs were chosen this study. Each femur underwent THA, by ETO tension from 0 500N vertical...
An all-fiber magnetic-field sensor combining a multicore fiber taper and magnetic fluid is proposed experimentally demonstrated. The sensing mechanism investigated theoretically experimentally. Experimental results demonstrate that the dip-wavelength of regularly varies with changes applied field. measuring sensitivity achieved to be ~34 pm/Gs in induction intensity range 50-300 Gs. Moreover, responding 50-Hz alternating field also investigated, minimal detectable ~23.7 Gs successfully...
Abstract Background Transforaminal percutaneous endoscopic lumbar surgeries (PELS) for disc herniation and spinal stenosis are growing in popularity. However, there some problems the establishment of working channel foraminoplasty such as nerve blood vessel injuries, more radiation exposure, steeper learning curve. Rapid technological advancements have allowed robotic technology to assist surgeons improving accuracy safety surgeries. Therefore, purpose this study is develop a robot-assisted...
The monitoring of acoustic waves is essential for a variety applications, ranging from photoacoustic imaging to industrial non-destructive evaluation and monitoring. Optical sensors have many advantages over electrical counterparts such as passivity immunity electromagnetic interference, can be quite compact with all-fiber structures. A common approach optically detect the acoustically induced mechanical movement cantilever or reflective membrane. However, based on moving parts limitations,...
