Detection of blackbody radiation during fiber guided laser-tissue vaporization.

Laser-tissue vaporization through a fiber catheter is evolving into a major category of surgical operations to remove diseased tissue. Currently, during a surgery, the surgeon still relies on personal experience to optimize surgical techniques. Monitoring tissue temperature during laser-tissue vaporization would provide important feedback to the surgeon; however, simple and low-cost temperature sensing technology, which can be seamlessly integrated with a fiber catheter, is not available. We propose to monitor tissue temperature during laser-tissue vaporization by detecting blackbody radiation (BBR) between 1.6 µm-1.8 µm, a relatively transparent window for both water and silica fiber. We could detect BBR after passing through a 2-meter silica fiber down to ∼70°C using lock-in detection. We further proved the feasibility of the technology through ex vivo tissue studies. We found that the BBR can be correlated to different tissue vaporization levels. The results suggest that this simple and low-cost technology could be used to provide objective feedback for surgeons to maximize laser-tissue vaporization efficiency and ensure the best clinical outcomes.
Ultraminiature Circularly Polarized RFID Antenna Inspired by Crossed Split-Ring Resonator

This article presents a novel ultraminiature circularly polarized (CP) antenna inspired by crossed split-ring resonators (SRRs), and its derivative forms with frequency and polarization re-configurability for radio frequency identification (RFID) applications. A novel resonator structure with two metal–insulator–metal (MIM) capacitors that is inspired by vertical SRR (VSRR) is first proposed, which could be easily miniaturized while achieving a reasonable high radiation gain. Two crossed dual-capacitance ring resonators (C-DRRs), which can be equivalent to two crossed magnetic dipoles, are then arranged perpendicularly and excited simultaneously with an SMA connector. Only an aluminum ground sheet, metallic screws, and a thin low-cost dielectric PCB board are used, where the dielectric loss is substantially minimized. This SRR-inspired CP antenna, as well as its frequency and polarization reconfigurable derivative by introducing a mechanically tunable inductor or using electrically controllable components, are analyzed and experimentally demonstrated, respectively. The developed antenna achieves an electrically small size of 0.135 <inline-formula> <tex-math notation="LaTeX">$\lambda _{0}\,\,\times $ </tex-math></inline-formula> 0.135 <inline-formula> <tex-math notation="LaTeX">$\lambda _{0}\,\,\times $ </tex-math></inline-formula> 0.045 <inline-formula> <tex-math notation="LaTeX">$\lambda _{0}$ </tex-math></inline-formula>, and its size is considerably smaller than other reported compact RFID reader antennas. The measured −10 dB bandwidth, peak gain, and radiation efficiency are 3.1% (900–928 MHz), 5.51 dBic, and 86.5%, respectively, which agree perfectly with the simulation. They demonstrate superior advantages in terms of ultracompact size, low-cost, wide axial ratio (AR) beam-width, high efficiency, and easy fabrication/assembling for RFID-related applications.
Silicon wafer etching by pulsed high-power inductively coupled Ar/CF4 plasma with 150 kHz band frequency

A silicon wafer etching using a burst pulse high-power inductively coupled plasma (ICP) is investigated. A 200 μs wide burst of a 157 kHz power supply is employed to generate ICP with a repetition rate of 50 Hz. A rectangular pulsed voltage synchronized with the burst power supply is applied upto 1 kV at the wafer. Mixed gas of argon (Ar) and tetrafluoromethane (CF4) is supplied into the vacuum chamber. The plasma density and electron temperature are 1019 m−3 and 2.8 eV where the wafer is, respectively. In the case of Ar plasma, the silicon etching rate is 0.01 μm min−1 with 1000 V negative bias. The etching rate increases to 0.23 μm min−1 by adding CF4 into Ar and increases linearly with increasing the bias voltage. The target current and emission intensity of Ar+ and F* are depended on bias voltage from −300 to −1000 V. The etching rate sharply increases by increasing CF4 content from 0% to 10%, and it becomes almost constant at 10%. The dependency of emission intensity of F* on CF4 content is similar to the dependency the etching rate.
A Review of Radio Frequency Fingerprinting Techniques

Radio frequency (RF) fingerprinting techniques have been used as an extra security layer for wireless devices. Unique fingerprints are used to identify wireless devices in order to avoid spoofing or impersonating attacks. These unique features can be extracted from imperfections of analog components during the manufacturing. This paper presents a general review of recent progress on RF fingerprinting techniques. Several studies are investigated for RF fingerprinting using different parts of a signal. The majority of these studies have been focused on the transient part of the signal. For this purpose, the transient signal must be extracted precisely. A number of common techniques of transient extraction are theoretically analyzed in this review. Then, some other approaches using the modulated part of the signal are also discussed. For all these approaches, the applied methodologies, the classification algorithms and a taxonomy of features are described. A comprehensive overview of the methods in RF fingerprinting is presented to demonstrate the state-of-the-art works.
Detection of Resting Zones Based on PSPNet in Salmon Scale Images

Sustainable fisheries resource management is essential due to the increasingly poor catch of chum salmon in Japan. This paper presents a neural network-based method for detecting resting zones in salmon scale images. Specifically, the proposed method uses a semantic segmentation model that is trained to effectively recognize scales with different shapes and patterns. Automation of the fast detection of resting zones can increase the utilization of the database of migrating chum salmon and contribute to our analysis of poor catches.
The challenges of expanding recognition of prior learning (RPL) in a collectively organised skill formation system: the case of Switzerland

ABSTRACT In many parts of the world, recognition of prior learning (RPL) is considered to be an important means of improving access to VET qualifications. In Switzerland – the country with arguably the highest rates of company-based VET at upper secondary level – adults with work experience of at least 5 years have had the option of accessing VET qualifications at the upper secondary level through RPL for more than 10 years now. Still, today, only roughly 6 percent of adults (over 25 years) who achieve a VET qualification make use of that option. The rest either pursue a regular VET programme, or at least take the ordinary final VET exam. This article discusses the reasons underlying this slow rate of RPL expansion in Switzerland. Arguing from a historical-institutionalist perspective, the article shows how the institutional framework of mainly company-based Swiss VET and the underlying actor coalition pose substantial barriers to the expansion of RPL. Nevertheless, by comparing different rates of RPL uptake across a range of economic sectors and different parts of the country, this article brings to light some key factors that promote the expansion of RPL.
Strategic positioning, differentiation and performance of Brazilian wineries

Purpose The purpose of this study is to verify whether managers’ strategic orientation influences decision-making related to differentiation and whether these two factors impact on the performance of the firms in the Brazilian wine industry. Design/methodology/approach A survey was conducted with representatives from 123 wineries located in the following Brazilian states: 78.86 per cent in Rio Grande do Sul; 13.01 per cent in Santa Catarina; 2.44 per cent in Paraná; 2.44 per cent in São Paulo; 1.63 per cent in Bahia; and 1.63 per cent in Pernambuco. The data were analyzed using multivariate statistical techniques, resulting in a structural equations model of the constructs. Findings The research findings show that there is a positive association between prospector orientation and differentiation. Analyst positioning was negatively associated with differentiation of winery companies. It was also possible to show that differentiation has a positive relationship with performance. Originality/value While a previous study attempted to identify wineries’ strategic orientation using other theoretical constructs, this study makes a contribution to consolidating reflections on strategic orientation focused on differentiation and performance. The results contribute to expanding the scientific debate by filling a gap in existing theory and also provide information of use to decision-makers, demonstrating, which approaches improve differentiation, and hence, performance.

Event-Triggered Model Predictive Control for Power Converters

In this letter, an event-triggered model predictive control (ET-MPC) method for power converters is presented. In the proposed method, the model predictive control (MPC) scheme is triggered only when the state of the converter exceeds a preset threshold; otherwise, the MPC scheme is suspended and the control signal is held as constant. Therefore, compared with the conventional MPC with finite control set (FCS-MPC), the ET-MPC method has the advantages of less computational burden and less switching actions, which contribute to lower switching losses, while ensuring satisfactory regulation performance. A buck converter prototype is adopted to validate the performance of ET-MPC. The results from the comparison with FCS-MPC demonstrate the effectiveness of the proposed ET-MPC method.
Governing body nurses’ experiences of clinical commissioning groups: an observational study of two clinical commissioning groups in England

Clinical commissioning groups were set up under the Health & Social Care Act (2012) in England to commission healthcare services for local communities. Governing body nurses provide nursing leadership to commissioning services on clinical commissioning groups. Little is known about how nurses function on clinical commissioning groups. We conducted observations of seven formal meetings, three informal observation sessions and seven interviews from January 2015 to July 2015 in two clinical commissioning groups in the South of England. Implicit in the governing body nurse role is the enduring and contested assumption that nurses embody the values of caring, perception and compassion. This assumption undermines the authority of nurses in multidisciplinary teams where authority is traditionally clinically based. Emerging roles within clinical commissioning groups are not based on clinical expertise, but on well-established new public management concepts which promote governance over clinically-based authority. While governing body nurses claim an authority located in clinical and managerial expertise, this is contested by members of the clinical commissioning group and external stakeholders irrespective of whether it is aligned with clinical knowledge and practice or with new forms of management, as both disregard the type of expertise nurses in commissioning embody.
Functional outcome of calcaneal locking compression plate

Background: The calcaneus is the frequently injured tarsal bone.75% of calcaneal fractures are intraarticular. Treating calcaneal fractures is a challenge for orthopaedic surgeon due to complex fracture pathology. Our aim is to evaluate the functional outcome of calcaneum Locking compression plate in patients with intraarticular calcaneal fractures with Bohler’s angle <20 degree who are admitted in the department of Orthopaedics, Government Medical College, Kottayam. Methods: In this study, 41 patients with 42 intraarticular calcaneal fractures were operated on with locking compression plate through lateral approach during the period of July 2015 to December 2016. Radiological evaluation done with X-rays. Bohler’s angle was measured from lateral view and those patients with angle <20 0 were selected for study. Patients were followed up clinically and radiologically for 24 weeks. Radiological assessment was done by Bohlers angle. Functional outcome was assessed using American Orthopaedic Foot and Ankle Society (AOFAS) scale. Results: At 24 weeks follow up, 90.5% of the study population had excellent to good functional outcome and 9.5% had fair and none had poor result. All patients had stable hind foot with all having good dorsiflexion and plantar flexion. But some patients had limited inversion and eversion. The mean postoperative Bohler’s angle was 30.02±3.97. Conclusions: Open reduction and internal fixation with locking compression plate gives sound functional outcome, if the surgery is well timed. Anatomical articular reduction especially of the posterior facet to be achieved and restoration of Bohler’s angle to normal range to be attempted.
Multi-Level Attention Based Coreference Resolution With Gated Recurrent Unit and Convolutional Neural Networks

Aiming at the diversity of the entity mentions in the field of animal husbandry in Tibet, the reference resolution model Att-GRU-CNN based on multi-level attention mechanism is proposed. The model uses GRU network for global semantic feature learning and knowledge memory, and uses CNN network to further extract local high-level semantic features. A word-level attention layer is added on the GRU hidden layer, the feature vector of entity mention does dot product operation with the feature vector of each word, and the result is normalized and used as the weight value distribution of the words, thus, the prior knowledge that the mention is the most important in the context is given to the network; A sentence-level attention layer is added on the CNN convolution layer, the convolutional layer output and entity name library matrix do association operation, and the result is used as the weight value distribution of the sentence, so as to strengthen the relation between the sentence where the mention is located and the entity scientific name. At the same time, the data enhancement technology is used to improve the generalization ability of the model. Finally, the ablation experiment on Tibetan animal husbandry dataset verified the effectiveness of each component of the model and the superposition effect after combination; the performance comparison experiment is carried out on public datasets MUC, B3 and CEAF $\varphi _{4}$ . The experimental results show that this model has a significant improvement over other models in the accuracy rate, recall rate and F1 score.

A New Phasor Estimator for PMU
Applications: P Class and M Class

Phasor measurement units (PMUs) are fundamental tools in the applications of modern power systems, where synchronized phasor estimations are needed. The accuracy and dynamic performance requirements for phasor, frequency, and rate of change of frequency (ROCOF) estimations are established in the IEEE Std. C37.118. 1-2011 along with the IEEE Std. C37.118. 1a-2014, where two PMU performances are suggested: P class filters for applications requiring fast response and M class filters for applications requiring high rejection to aliased signals. In this paper, a methodology to design new phasor estimators that satisfy the P class and M class requirements in PMUs is presented. The proposed methodology is based on finite impulse response filters, brick-wall filters, and complex filter design concepts, where frequency range, time performance, harmonic rejection and out-of-band interference requirements are considered in its design. A comparative analysis using the reference model given by the IEEE Std. C37.118. 1 is presented. The results show the effectiveness of the phasor estimators under steady-state and dynamic conditions according to the PMU standard, making them suitable tools for applications in power systems.

Traditional Chinese medicine-based neurorestorative therapy for Alzheimer’s and Parkinson’s disease

The prevalence of multiple neurodegenerative diseases, such as Alzheimer’s disease (AD) and Parkinson’s disease (PD), has been dramatically increasing, particularly in the aging population. However, the currently available therapies merely alleviate the symptoms of these diseases and are unable to retard disease progression significantly. Traditional Chinese medicine (TCM) has been used in clinical practice for thousands of years for ameliorating symptoms or interfering with the pathogenesis of aging- associated diseases. Modern pharmacological studies have proved that TCM imparts disease-modifying therapeutic effects against these diseases, such as protection of neurons, clearance of protein aggregates, and regulation of neuroinflammation. This review summarizes the evidence from recent studies on AD and PD therapies regarding the neuroprotective activities and molecular mechanisms of a series of TCM formulations comprising herbs and their active ingredients. The findings of this review support the use of TCM as an alternative source of therapy for the treatment of neurodegenerative diseases.
Effects of Garcinia hydroxybiflavanonol-1 (GB1) isolated from Garcinia kola Heckel (Guttiferae) seeds on reproductive toxicity induced with cadmium chloride (CdCl2) in male Wistar rats

To examine the effects of Garcinia hydroxybiflavanonol-1 (GB1) isolated from seeds of Garcinia kola Heckel (Guttiferae) on reproductive toxicity induced with cadmium chloride (CdCl2) in male Wistar rats. Rats were randomly assigned to Groups 1 to 3 (n = 12) as follows; A: control, B: CdCl2 only group, C: CdCl2+GB1. Cadmium toxicity was induced by including 2.5 mg/kg of CdCl2 into the rats’ drinking water and GB1 was dissolved in 0.5 % Tween20 and administered per os daily for 90 days. Four (4) animals from each group was humanely euthanized every 30 days. The testes were exteriorized and sperm cells collected from the caudal epididymis for analysis and histology.The result showed accumulation of Cadmium (Cd) in the testes of Wistar rats and a significant decrease (p< 0.05) in sperm count and sperm motility in Group B compared to Groups A and C. There was also a significant increase (p< 0.05) in immotile sperm count, headless sperm count and sluggish sperm count in Group B. Histology results revealed that CdCl2 significantly reduced the volume of spermatozoa in the seminiferous tubules and resulted in reduced spermatogenesis observed, in reduced number of sperm counts and histology. Amelioration with GB1 restored the testicles to normal spermatogenic activities after 90 days of treatment.
