Low‐noise wide‐bandwidth DNA readout instrument for nanopore applications
Authors: Yun J. , Choi H. , Kim J.
Published: April 2017

A low‐noise, wide‐bandwidth DNA readout instrument for nanopore applications is presented. Owing to hardware simplicity and reliability, a resistive‐feedback transimpedance amplifier (rf‐TIA) is adopted as the headstage for the readout instrument. However, to achieve a high gain and low input noise, its high feedback resistance induces a high parasitic capacitance, thus significantly limiting the 3 dB bandwidth. To drastically reduce the parasitic capacitance and widen the bandwidth, a novel rf‐TIA architecture is fabricated that utilises a split‐resistor technique for the high feedback resistor. This is demonstrated in a benchtop test employing an α‐haemolysin nanopore.
Short‐circuit current reduction techniques of the doubly‐fed induction generator based wind turbines for fault ride through enhancement
Authors: El‐Naggar Ahmed , Erlich Istvàn
Published: April 2017

Grid voltage disturbances result in high magnitudes of rotor currents and DC‐link voltage of the doubly‐fed induction generator based wind turbines (DFIG‐WTs), which may lead under severe fault conditions into deactivation of the machine side converter (MSC) and violation of the fault ride through (FRT) requirements of the grid codes. In this essence, several solutions were proposed, which vary between installing extra hardware components and control modification. However, the extra costs as well as the control limitations degrade the feasibility of the proposed solutions. In this study, new techniques are proposed to enhance the FRT through peak short‐circuit current reduction of the DFIG‐WT. The new techniques are developed based on the open‐loop and close‐loop dynamic response of the DFIG. The new techniques utilise the available MSC voltage, in order not to violate the voltage limits, to increase the rate of change of the DFIG internal transient voltage and to increase the magnitude of the transient impedance. Additionally, the mean variance mapping optimisation is used to optimally tune the gains in the second two techniques. The new techniques were implemented in a manufacturer‐based simulation model, and the simulation results show their effectiveness, where the maximum peak current reduction achieved was 23.6%.

This study considers the design and testing of a laboratory scale test rig for wave energy converters (WECs). The main element of the test rig is a double‐sided permanent magnet linear generator (PMLG). In this study, the authors describe the detailed design of the PMLG. The objective of the design is to find the detailed parameters of the PMLG to meet the targeted electromotive force (EMF) voltage with respect to the designed physical constraints. The design procedure is easy to follow and emphasises the practical aspects to construct the PMLG. A spreadsheet table was generated using the procedure to find the design parameters. Therefore, a designer can easily modify the parameters based on the physical constraints and the targeted EMF voltage. In addition to that, the authors explain the procedure to find the rating temperature for the generator. Finally, this PMLG is integrated with other components to form the test rig. The experiment is conducted to show how close the performance of the constructed PMLG is, in term of its EMF voltage and rated thermal, to the designed values. Additional tests were also conducted to test the performance of the test rig using various scenarios similar to ocean wave profiles.
Takagi–Sugeno fuzzy model‐based approach considering multiple weather factors for the photovoltaic power short‐term forecasting

Published: April 2017

With the increasing contribution of the power production by the photovoltaic (PV) systems to the electricity supply, the PV power forecasting becomes increasingly important. There are many factors influencing the forecasting performance, such as the air temperature, humidity, insolation, wind speed, wind direction and so on. This study proposes a Takagi–Sugeno (T–S) fuzzy model‐based PV power short‐term forecasting approach. First, by means of the correlation analysis, the influential factors are selected as the model inputs. Then, the fuzzy c‐mean clustering algorithm and the recursive least squares method are used to identify the antecedent and the consequent parameters. The performance of the proposed forecasting approach is tested by using a large database of measurement data from the 433kW PV array at St Lucia campus of The Queensland University of Australia. The forecasting results are compared with the support vector machine (SVM), the hybrid of empirical mode decomposition and SVM, the back propagation neural network and the recurrent neural network. The results indicate that, compared with the existing approaches, the proposed T–S fuzzy model‐based forecasting approach is simpler and can forecast more accurately.

Authors: Gupta Amit , Kumar Rakesh , Ojha Bal , Chandra Anil
Published: April 2017

Malignant peripheral nerve sheath tumors (MPNSTs) are rare neoplasms, usually arising from components of nerve sheath such as perineural fibroblasts or Schwann cells. Primary scalp MPNST is an exceptionally rare entity and only few cases have been reported till date. We encountered an unusual case of giant scalp MPNST in a 70-year-old man without any history suggestive of neurofibromatosis associated with intracranial extension with underlying bone destruction. The tumor was treated with complete surgical excision followed by adjuvant radiotherapy. Histopathological examination showed hyper- and hypocellular areas of spindle cells admixed with myxoid areas and immunohistochemistry revealed positivity to vimentin and S100 on the basis of which the diagnosis of MPNST was made.

Hydrocephalus is present in 1 of every 1,000 newborns treated with ventriculoperitoneal shunts (VPSs) in the majority of cases. This procedure carries a high risk of complications. One of them is the mechanical disconnection of the system that leads to dysfunction of the shunt and implies neurologic changes that the neurosurgeon has to address as soon as possible. We present two cases of congenital hydrocephalus previously treated with ventriculoperitoneal shunts. The first patient was hit on the right side of his neck. The day after the event, the patient was hypoactive and unable to communicate properly with the examiner and his parents. The radiological cervical X-ray showed disconnection of the catheter at the cervical level. The second case was of a 37-year-old man with hydrocephalus managed with VPS for the first time at the age of 14 years, who was brought to emergency due to rapid onset of symptoms apparently associated with trauma related to a blow with a soccer ball; the patient's X-ray showed fracture of the catheter's path at the thoracic level. For both cases, surgical repair was needed. Results were good, and the patients showed rapid neurologic improvement.

A 53-year-old female patient was referred to us with a posttraumatic frontoorbital deformity following motor vehicle accident after 2 months of her injury. Using the virtual surgical planning software, comprehensive analysis of the deformity, and preoperative planning was simulated. The reconstruction of the defect was then determined and approximated to the skull of the reference database. Patient-specific implant is manufactured by selected laser melting of titanium powder grade 2, which yielded a highly accurate personalized implant. The good postoperative outcome was satisfactorily achieved. The postoperative result was also comparable to the predicted outcome as showed via chromatographic analysis method. Not only being less invasive, the operative time was also remarkably reduced as compared with the conventional reconstruction method of similar cases.

Published: April 2017

Lactate threshold (LT) is one of the physiological parameters usually used in rowing sport training prescription because it indicates the transitions from aerobic to anaerobic metabolism. Assessment of LT is classically based on a series of values of blood lactate concentrations obtained during progressive exercise tests and thus has an invasive aspect. The feasibility of noninvasive LT estimative through bioelectrical impedance spectroscopy (BIS) data collected in thigh muscles during rowing ergometer exercise tests was investigated. Nineteen professional rowers, age 19 (mean) ± 4.8 (standard deviation) yr, height 187.3 ± 6.6 cm, body mass 83 ± 7.7 kg, and training experience of 7 ± 4 yr, were evaluated in a rowing ergometer progressive test with paired measures of blood lactate concentration and BIS in thigh muscles. Bioelectrical impedance data were obtained by using a bipolar method of spectroscopy based on the current response to a voltage step. An electrical model was used to interpret BIS data and to derive parameters that were investigated to estimate LT noninvasively. From the serial blood lactate measurements, LT was also determined through Dmax method (LTDmax). The zero crossing of the second derivative of kinetic of the capacitance electrode (Ce), one of the BIS parameters, was used to estimate LT. The agreement between the LT estimates through BIS (LTBIS) and through Dmax method (LTDmax) was evaluated using Bland-Altman plots, leading to a mean difference between the estimates of just 0.07 W and a Pearson correlation coefficient r = 0.85. This result supports the utilization of the proposed method based on BIS parameters for estimating noninvasively the lactate threshold in rowing.

Graphene has attracted much attention at various research fields due to its unique optical, electronic and mechanical properties. Up to now, graphene has not been widely used in optoelectronic fields due to the lack of large-area uniform doped graphene (n-doped and p-doped) with smooth surface. Therefore, it is rather desired to develop some effective doping methods to extend graphene to optoelectronics. Here we developed a novel doping method to prepare large-area (> centimeter scale) uniform doped graphene film with a nanoscale roughness(RMS roughness ∼1.4 nm), the method (nano-metal film doping method) is simple but effective. Using this method electron doping (electron-injection) may be easily realized by the simple thermal deposition of Ag nano-film on a transferred CVD graphene. The doping effectiveness has been proved by Raman spectroscopy and spectroscopic ellipsometry. Importantly, our method sheds light on some potential applications of graphene in optoelectronic devices such as photodetectors, LEDs, phototransistors, solar cells, lasers etc.
CC2 oscillator strengths within the local framework for calculating excitation energies (LoFEx)
Authors: Baudin Pablo , Kjærgaard Thomas , Kristensen Kasper
Published: April 2017

In a recent work [P. Baudin and K. Kristensen, J. Chem. Phys. 144, 224106 (2016)], we introduced a local framework for calculating excitation energies (LoFEx), based on second-order approximated coupled cluster (CC2) linear-response theory. LoFEx is a black-box method in which a reduced excitation orbital space (XOS) is optimized to provide coupled cluster (CC) excitation energies at a reduced computational cost. In this article, we present an extension of the LoFEx algorithm to the calculation of CC2 oscillator strengths. Two different strategies are suggested, in which the size of the XOS is determined based on the excitation energy or the oscillator strength of the targeted transitions. The two strategies are applied to a set of medium-sized organic molecules in order to assess both the accuracy and the computational cost of the methods. The results show that CC2 excitation energies and oscillator strengths can be calculated at a reduced computational cost, provided that the targeted transitions are local compared to the size of the molecule. To illustrate the potential of LoFEx for large molecules, both strategies have been successfully applied to the lowest transition of the bivalirudin molecule (4255 basis functions) and compared with time-dependent density functional theory.
Temperature of maximum density and excess properties of short-chain alcohol aqueous solutions: A simplified model simulation study
Authors: Furlan A. P. , Lomba E. , Barbosa M. C.
Published: April 2017

We perform an extensive computational study of binary mixtures of water and short-chain alcohols resorting to two-scale potential models to account for the singularities of hydrogen bonded liquids. Water molecules are represented by a well studied core softened potential which is known to qualitatively account for a large number of water’s characteristic anomalies. Along the same lines, alcohol molecules are idealized by dimers in which the hydroxyl groups interact with each other and with water with a core softened potential as well. Interactions involving non-polar groups are all deemed purely repulsive. We find that the qualitative behavior of excess properties (excess volume, enthalpy, and constant pressure heat capacity) agrees with that found experimentally for alcohols such as t-butanol in water. Moreover, we observe that our simple solute under certain conditions acts as a “structure-maker,” in the sense that the temperature of maximum density of the bulk water model increases as the solute is added, i.e., the anomalous behavior of the solvent is enhanced by the solute.
Effects of ordered islands on surface resistivity: Ni on Au(111)
Authors: Cohen Joshua I. , Tobin R. G.
Published: April 2017

The change in surface resistivity due to the formation of nickel islands on gold(111) was studied by measuring the resistance of a thin film of Au as a function of Ni coverage, θ. Previous studies showed that the Au(111) herringbone reconstruction provides a template for the periodic growth of ordered islands. Ni islands grow radially until θ ≈ 0.3 ML, after which subsequent Ni atoms contribute primarily to a second layer. Since Ni atoms on Au(111) grow in ordered nanoclusters, a nonlinear dependence of resistance on θ might be anticipated. Our results, however, show a linear dependence for Ni atoms in the first layer, as if they were independent point scatterers. Above θ ≈ 0.3 ML, there is little change in resistivity, which we attribute to Ni atoms in the second layer making no significant contribution to the resistivity. Although we did not directly image the islands, our results are consistent with the growth model and structures previously observed with scanning tunneling microscopy. Our results serve as an indirect probe of the growth kinetics of this system, as well as determining the contributions of Ni islands to the surface resistivity of the Au film.
