Nanotube Tunneling FET With a Core Source for Ultrasteep Subthreshold Swing: A Simulation Study

In this article, we propose a novel nanotube (NT) tunneling field-effect transistor with a core source (CSNT-TFET) which uses line tunneling. We systematically investigate the CSNT-TFET with the help of calibrated 3-D simulations and demonstrate that it outperforms the conventional NT-TFET in terms of both static and dynamic performance. We show that the CSNT-TFET exhibits a reduced average subthreshold swing (SS) of 33 mV/decade with Ge-source for more than eight orders of magnitude of drain current at an ultralow supply voltage (<inline-formula> <tex-math notation="LaTeX">${V}_{\text {DS}}= {0.3}$ </tex-math></inline-formula> V). In addition, the ON-state current of the CSNT-TFET is enhanced by ~13 times with Si-source and by ~6 times with Ge-source even at <inline-formula> <tex-math notation="LaTeX">${V}_{\text {DS}}= {V}_{\text {GS}}= {0.3}$ </tex-math></inline-formula> V when compared with the NT-TFET. Without the use of any exotic material for the source and channel regions, the CSNT-TFET offers an impact ionization MOS-like steep SS (a minimum SS<sub>point</sub> of ~1 mV/decade) and a high ON-state current of ~10<sup>−6</sup> A for <inline-formula> <tex-math notation="LaTeX">${V}_{\text {DS}}= {V}_{\text {GS}}= {0.3}$ </tex-math></inline-formula> V. Furthermore, the impact of the gate sidewall spacer and source diameter on the performance of the CSNT-TFET is also investigated.
Application of Naïve Bayesian sequential analysis to primary care optometry

The objective of this study was to investigate the effects of circularity, comorbidity, prevalence and presentation variation on the accuracy of differential diagnoses made in optometric primary care using a modified form of naive Bayesian sequential analysis. No such investigation has ever been reported before. Data were collected for 1422 cases seen over one year. Positive test outcomes were recorded for case history (ethnicity, age, symptoms and ocular and medical history) and clinical signs in relation to each diagnosis. For this reason only positive likelihood ratios were used for this modified form of Bayesian analysis that was carried out with Laplacian correction and Chi-square filtration. Accuracy was expressed as the percentage of cases for which the diagnoses made by the clinician appeared at the top of a list generated by Bayesian analysis. Preliminary analyses were carried out on 10 diagnoses and 15 test outcomes. Accuracy of 100% was achieved in the absence of presentation variation but dropped by 6% when variation existed. Circularity artificially elevated accuracy by 0.5%. Surprisingly, removal of Chi-square filtering increased accuracy by 0.4%. Decision tree analysis showed that accuracy was influenced primarily by prevalence followed by presentation variation and comorbidity. Analysis of 35 diagnoses and 105 test outcomes followed. This explored the use of positive likelihood ratios, derived from the case history, to recommend signs to look for. Accuracy of 72% was achieved when all clinical signs were entered. The drop in accuracy, compared to the preliminary analysis, was attributed to the fact that some diagnoses lacked strong diagnostic signs; the accuracy increased by 1% when only recommended signs were entered. Chi-square filtering improved recommended test selection. Decision tree analysis showed that accuracy again influenced primarily by prevalence, followed by comorbidity and presentation variation. Future work will explore the use of likelihood ratios based on positive and negative test findings prior to considering naive Bayesian analysis as a form of artificial intelligence in optometric practice.
In Search of Meaningful Work on Digital Freelancing Platforms: The Case of Design Professionals

"Growth of the platform economy has been accompanied by critiques of the fragmented, isolated and precarious nature of the employment it offers. Yet, little is known about how creative freelancers perceive the meaning of work on the platforms. Based on 40 interviews with freelancers, clients, platform owners and industry experts, this paper reveals that most freelancers are concerned about how operating through the platform, and their dependence on it, is undermining the meaningfulness of their work. Freelancers find that the platforms are eroding both the manifest (i.e. monetary) and latent (i.e. non‐monetary) meaning of their work although they are mostly concerned about the latent element of meaning. The analysis reveals that the small group of freelancers who pursue meaningful work and earn a sustainable income on platforms are those with strong entrepreneurial orientation. "
Advanced Robustness Control of DC–DC Converter for Proton Exchange Membrane Fuel Cell Applications

The fuel cell output power depends highly on the random load profile, and power converters play a key role in the fuel cell power system. Robust control design of the converter can help to design online control and optimize the diagnostic method for fuel-cell-based applications. In this article, an advanced control algorithm of the dc–dc converter for the proton exchange membrane fuel cell is realized through a robustness algorithm based on flatness control and active disturbance rejection control (ADRC). Flatness control can track the power demand, and ADRC can help to estimate the total required power in real time. The effectiveness of the proposed control method is verified through a two-phase interleaved boost converter (TIBC), and results indicate that the steady-state error of TIBC's output voltage can be decreased. Besides, the proposed control scheme is not sensitive to system parameter variations, and it can balance the power among each phase accurately. Moreover, the flatness–ADRC control can guarantee the smooth output of the converter when load disturbance occurs. The simulation and experimental results all indicate that strong robustness can be obtained when compared with the conventional proportional integral control method. The simple architecture of the controller makes it easier to be implemented in real-time online applications.
Mini-term 4.0. A Real-time Maintenance Support System to Prognosticate Breakdowns in Production Lines

This paper presents a Real-time Maintenance Support System (MSS) to prognosticate breakdowns in production lines. The system is based on the sub-cycle time monitoring, mini-terms, and how the sub-cycle time variability can be used as a deterioration indicator that could describe the dynamic of the failure for the machine parts. A Real-time MSS has been installed at Ford factory located in Almussafes (Valencia), the so-called Mini-term 4.0. At present, three plants, Body 1,2 and 3 have hundreds of mini-terms sensed by the system. The connected production line elements are the welding guns, elevators, screwdriver and scissor tables. Mini-term 4.0 uses the well-known k-means algorithm to detect change points. The K-means constructs two groups and, when centroid values differ more than 7 % (orange alert), or 18 % (red alert), an e-mail is sent to maintenance team to schedule the maintenance task. Some examples of the different change point topologies detected are shown at the end of the paper.
Intelligent mobile walking-aids: perception, control and safety

Robot-assisted walking has become a popular research field for helping mobility-limited people to walk more easily. Different from other walking-aid devices (e.g. exoskeletons and prosthesis), intelligent mobile walking-aids (IMWs) are invented for helping the visually impaired or people in need (e.g. the elderly) to walk in daily life. This paper reviews various related literatures on IMWs and dwells on three kinds of perception systems and perception algorithms of IMWs to explain how IMWs understand the user's motion states or tendency. Besides, the control strategies of IMWs under the normal case concerned are classified and compared. The safety measures for preventing the user from abnormal cases (e.g. encountering obstacles, the user's stumbling and falling, faults of IMWs) are introduced in detail as well. The performance of current safety measures for the user's fall detection and prevention has been evaluated and concluded. At the end of the article, the discussion and perspective of IMWs are presented. GRAPHICAL ABSTRACT
Point of care intravenous anaesthetic measurement in anaesthesia and critical care

Maintenance of anaesthesia using the intravenous agent propofol has increased following development of pharmacokinetic models. An analyser capable of determining propofol concentrations at the point of care may lead to an improved accuracy of drug delivery. Validation work on a novel analyser measuring propofol concentration in near real time demonstrate a high level of precision for samples in the clinical range. Further work in the clinical setting was carried out using the novel propofol analyser to further research its potential use in a diverse patient cohort. Studies were performed in intensive care correlating blood propofol concentrations with depth of sedation, demonstrating a correlation with organ failure. The Marsh model of Target Controlled Anaesthesia was poorer at predicting propofol concentration in patients with significant organ dysfunction than in those without organ failure (correlation coefficient 0.36 vs. 0.73 respectively). Studies in the operating room were performed in which measured propofol concentrations were compared with those predicted using the Marsh model. Results demonstrated significant inaccuracies of the model (bias 32%, precision -8.7 to 72.6%). A method of Marsh model bias correction using a single blood propofol measurement was tested. Results demonstrated insufficient predictability to allow a single point calibration.
An Introduction to OPC UA TSN for Industrial Communication Systems

The industrial communication market is dominated by Ethernet-based fieldbus systems. Although they share similar requirements and market segments, their implementations and ecosystems differ considerably. As a result, end customers and device manufacturers are faced with a multitude of technologies that need to be produced, run, diagnosed, maintained, and kept in stock. Although the availability of products and services is largely satisfactory, dealing with multiple solutions generates high costs and limits IoT capability. This paper introduces Open Platform Communication Unified Architecture Time-Sensitive Networking (OPC UA TSN) as a new technology and presents the current view. This time, the industrial prospects of fulfilling industrial communication requirements while leveraging the cost benefits of standard Ethernet hardware in the midterm are in reach. We anticipate that OPC UA TSN will reveal itself as a game changer in the field of industrial automation, being a candidate for establishing a holistic communication infrastructure from the sensor to the cloud.
AIDS-associated Kaposi's sarcoma in an Indian female.

Kaposis sarcoma (KS) is a neoplasm of multifocal origin which manifests primarily as multiple vascular nodules in the skin and other organs. Its association with HIV has been reported in America Africa and Europe. Extremely rare in HIV-infected women and children the condition is reported more commonly in homosexual males. It is suspected that female hormones may protect women against KS. The first case of AIDS-associated KS in a 35-year old Indian female prostitute is reported for its rarity and clinico-epidemiological implications in the Indian setting. The woman presented with multiple painless non-pruritic nodules of varying colors on the right leg with swelling since two months. There was no history of trauma discharge from the lesions or any treatment taken nor any history of blood transfusion IV drug use or sexually transmitted disease. On examination present mainly on the right leg were multiple nontender papulonodules reddish to purplish in color 2-10 mm in diameter and adherent to skin and underlying structures but not to the bone. Few discrete similar lesions were seen on the right forearm and left side of chin and left leg. Telangiectasia was noted on the anteromedial part of the right knee and ears and molluscum contagiosa on the front of the chest while bilateral non-pitting oedema was apparent up to the knee. Inguinal and supraclavicular lymph glands were palpable. A raised purplish plaque was seen on the hard palate and in front of the left upper lateral incisor on the gingiva with candidiasis of the dorsum of the tongue and there was congestion of the right lower palpebral conjunctiva while a systemic examination proved normal. The diagnosis of KS was confirmed by histopathology electron microscopy seropositivity and Pepti-LAV test and viral culture. Antibodies were found to HIV-1 and HIV-2 and HLA DR57 was positive on oligotyping. On treatment initially very few skin lesions flattened almost totally after intralesional injection of vincrysticine. Alpha interferon 200 IU sublingually daily showed amelioration in palatal gingival chin forearm and right leg lesions within a fortnight. The patient is receiving tab ketoconazole orally 200 mg bid for oral and esophageal candidiasis and tab cimetidine as an immunomodulator. Since cutaneous lesions of KS are radiosensitive local radiotherapy for leg lesions is contemplated.
Dijet Imbalance in 2.76 TeV PbPb Collisions in CMS

We report on dijet production in PbPb collisions at a nucleon-nucleon center-of-mass energy of 2.76 TeV studied with the CMS detector at the LHC. A large dijet momentum imbalance is observed in central PbPb collisions, which reduces in the more peripheral collisions. This observation is consistent with a jet quenching scenario, where the partons lose energy propagating through the hot and dense QCD medium. An initial study of γ-jet correlations is also presented.
Effect of Tight-fitting Sportswear of Different Compression Degrees on Variation Characteristics of sEMG on Vastus Medialis during Cycling Motion

Objective:Index data from sEMG were used to reflect the influence of different tight compression degrees on variation characteristics of sEMG on Vastus Medialis in different intensity load during cycling motion to fatigue,and then further explored its utilities and internal mechanism on muscle activity.Methods:Selected 10 young healthy male volunteers without cycling training experience randomly as subjects to complete uniform cycling motion to fatigue in moderate and high intensity load on bicycle ergometer with no compression,medium compression and high compression at lower limb respectively.Recorded The original signals of sEMG on Vastus Medialis through the motion process which was divided into 10 segments.After standardized processing of the data from iEMG and MF,compared and analyzed the differences between each set of data by three-factor variance analysis and Post Hoc Multiple Comparisons Test.Results:1) During the later stage of cycling motion,tight compression had influence on the change range of iEMG and MF,which was more obvious when it interacted with exercise intensity.2) Compared with no tight compression,medium tight compression could not change general increasing range of iEMG(%) and reducing range of MF(%) during this cycling movement in moderate-intensity load,which made both of them,however,declined during the later stage of cycling motion in high-intensity load.3) Compared with no tight compression,high tight compression made general increasing range of iEMG(%) and reducing range of MF(%) declined during the later stage of cycling motion in moderate-intensity load,which made both of them,however,increased during the later stage of cycling motion in high-intensity load.Conclusions:During the later stage of cycling motion,plus medium tight compression in high-intensity load and plus high tight compression in moderate intensity load showed similar effects on Vastus Medialis to maintain output power of muscle contraction and transmission rate of action potential,which may be helpful to delay the muscle fatigue and improve the sport performance to some extent.On the contrary,plus high tight compression accelerated muscle fatigue during the later stage of cycling motion in high-intensity load.
[Predictive factors for invasive pnuemococcal disease: a case-control study].

BACKGROUND Streptococcus pneumoniae causes significant morbidity in children, but data on the incidence of invasive pneumococcal disease in Spain are scarce. The objectives of this study were: 1) to describe the clinical and epidemiological features of invasive pneumococcal disease in our health district and 2) to determine factors predictive of invasive pneumococcal disease in febrile children seen at a hospital Emergency Department. MATERIAL AND METHODS Design. Observational, retrospective, case-control study, from 1 October, 1992 to 31 March, 2001. LOCATION Community Hospital in the north of Spain. Entry criteria for cases: febrile children under 14 years of age, seen at the Emergency Department during the study period, with growth of S. pneumoniae in the blood culture. Eligibility criteria for controls: febrile children under the age of 14 years seen at the Emergency Department during the study period with no bacterial growth in the blood culture. The first eligible child seen after each case was included as a control. STATISTICAL ANALYSIS descriptive analysis of patients with invasive pneumococcal disease and univariate analysis of each variable in relation to the dependent variable (blood culture positive for S. pneumoniae); multivariate analysis was performed using logistic regression techniques. RESULTS Seventy-six cases of invasive pneumococcal disease were studied. The mean incidence of invasive pneumococcal disease (cases/100,000 children/year) was 174.1 for children under 24 months of age, 38.9 for children aged 24-59 months, and 5.9 for children older than 59 months. The incidence of pneumococcal meningitis in children under 24 months of age was 14.8 cases/100,000 children/ year. The most common diagnoses were occult bacteremia (64.5 %), pneumonia (17.1 %), and meningitis (9.2 %). Mortality was 1.3 %. A total of 56.5 % of the S. pneumoniae strains showed penicillin resistance (11.8 % high-grade resistance) and 12.2 % showed cefotaxime resistance. Predictive factors for invasive pneumococcal disease were temperature greater than or equal to 39 degrees C (OR: 2.09; 95 % CI:91-4.79), generalized malaise (OR: 2.61; 95 % CI: 1.1-6.21), age between 6 and 36 months (OR: 4.06; 95 % CI: 1.79-9.21), and absolute neutrophil count (ANC) greater than or equal to 10,000 cells/mm3 (OR: 8.16; 95 % CI: 3.54-18.79). CONCLUSIONS 1. The incidence of invasive pneumococcal disease in our health district is high and is greater than that reported for other European regions. 2. In contrast, the incidence of pneumococcal meningitis is similar to that in other European countries. 3. The most frequent diagnosis was occult bacteremia. 4. In the case-control study, four variables showed significant independent association with the risk of invasive pneumococcal disease: temperature greater than or equal to 39 degrees C, general malaise, age between 6 and 36 months, and an ANC greater than or equal to 10,000 cells/mm3. The most powerful predictor of invasive pneumococcal disease in our series was ANC.

Understanding the Synergy between Percutaneous Coronary Intervention with Taxus and Cardiac Surgery (SYNTAX) Trial Implications for current and future clinical practice

markdownabstract__Abstract__ The landmark Synergy between Percutaneous Coronary Intervention with Taxus and Cardiac Surgery (SYNTAX) Trial1-4 has aided in reducing the area of uncertainty in decision making between percutaneous coronary intervention (PCI) and coronary artery bypass graft (CABG) surgery in patients with complex coronary artery disease.5-8 As part of the SYNTAX Trial, quantification of the coronary artery disease burden was undertaken with the anatomical SYNTAX Score (www.syntaxscore.com),9-11 and has since been implemented in international revascularisation guidelines.5-8 In addition, recognising the importance of quantifying coronary artery disease burden in decision-making between CABG and PCI, the US Food and Drugs Association mandates the SYNTAX Score as entry criteria in ongoing contemporary stent and structural heart disease trials. Namely, the EXCEL (Evaluation of XIENCE PRIME™ or XIENCE V® Everolimus Eluting Stent System Versus Coronary Artery Bypass Surgery for Effectiveness of Left Main Revascularization) Trial (ClinicalTrials.gov identifier: NCT01205776), and SURTAVI (Safety and Efficacy Study of the Medtronic CoreValve® System in the Treatment of Severe, Symptomatic Aortic Stenosis in Intermediate Risk Subjects Who Need Aortic Valve Replacement) Trial (ClinicalTrials.gov identifier: NCT01586910). The SYNTAX Trial was conceived in an era when the potential benefits of drug eluting stents were first being realised between 2002-2006.12-19 After multiple prior attempts comparing CABG against PCI using older technologies – namely plain ‘old’ balloon angioplasty (POBA) and bare metal stents (BMS) – in over 20 randomised trials,20, 21 including the Bypass Angioplasty Revascularization Investigation (BARI)22 and Coronary Angioplasty versus Bypass Revascularisation Investigation (CABRI)23 trials, the time had once again come to rechallenge the cardiac surgeons in the management of complex coronary artery disease. Historically one of the major criticisms of randomised trial design comparing CABG against PCI was that the trials enrolled highly selected, “cherry-picked,” patients, with approximately 2-12% of screened subjects actually randomised in most trials, and thus being largely unrepresentative of conventional clinical practice.20, 24 At the time of the SYNTAX Trial design, one of the key requirements put forth by seven cardiac surgeons, dubbed the “magnificent seven,” and fully endorsed by the clinical and interventional cardiologists at the time, was the need for an ‘all-comers’ trial design, free from selection bias.
