Veridical and False Recall in Adults Who Stutter
Authors: Byrd Courtney T. , Sheng Li , Ratner Nan Bernstein , Gkalitsiou Zoi 
Published: October 2014

Purpose
This study used a false memory paradigm to explore the veridical and false recall of adults who stutter.

Method
Twelve adults who stutter and 12 age-matched typically fluent peers listened to and then verbally recalled lists of words that consisted of either semantic or phonological associates or an equal number of semantic and phonological associates (i.e., hybrid condition) of a single, unpresented critical “lure” word. Three parameters of recall performance were measured across these 3 conditions: (a) number of accurately recalled words, (b) order of recall (primacy vs. recency effect), and (c) number of critical lures produced (i.e., false memories).

Results
Significant group differences were noted in recall accuracy specific to list type and also list position as well as relative to critical lure productions.

Conclusions
Results suggest that certain basic memory processes (i.e., recency effect) and the processing of gist semantic information are largely intact in adults who stutter, but recall of verbatim phonological information and subvocal rehearsal may be deficient.

Authors: Gimenez S.P. , Davini E. , Peruzzi V.V. , Renaux C. , Flandre D. 
Published: October 2014

The performance improvements for integrated circuit applications of silicon‐on‐insulator (SOI) metal–oxide semiconductor field‐effect transistors (MOSFETs) implemented with diamond layout style (hexagonal gate geometry) are quantified, thanks to the longitudinal corner effect and parallel association of MOSFETs with different channel lengths effect contributions. Futhermore, an accurate analytical drain current model for planar diamond SOI MOSFET for micrometre scale effective channel lengths is proposed and validated. The concept is then extended by 3D simulations for the 150 nm node fully‐depleted SOI n‐channel MOSFETs.

Published: October 2014

Practical implementations of power line communications (PLCs) with multiple‐input–multiple‐output (MIMO) generally suffer from crosstalk between ports. Presented is a crosstalk ratio (CR)‐based adaptive 2 × 2 MIMO PLC along with simulation results that demonstrate an improvement on conventional 2 × 2 MIMO PLC in terms of bit‐error‐rate.
Simultaneous process self‐calibration method using TDC for 3D DDR4 DRAM
Authors: Oh Reum , Jang J. , Kim J. , Sung Man Young 
Published: October 2014

Three‐dimensional (3D) dynamic random‐access memory (DRAM) with TSVs has been proposed due to continuous demands for low‐power and high‐density memory without IO loading limitation. However, the process difference among the stacked dies causes the timing mismatch of internal signals. To remove signal confliction and reduce signal skews among the stacked dies, the simultaneous process self‐calibration scheme is proposed. The stacked dies using the proposed scheme detect the slowest signal among the stacked dies and internal signals are aligned with the slowest signal at the same time. The time for aligned operation is within one read loop and the scheme is turned off after calibration to reduce additional standby current. The 3D double‐data rate 4 (DDR4) DRAM using the proposed scheme is operated over 2133 Mbit/s at 1.2 V.

Published: October 2014

The high‐frequency characteristics of high electron mobility transistors applying AlGaN for a channel layer (AlGaN channel HEMTs) with greater impacts of alloy disorder scattering than those in conventional HEMTs with a GaN channel layer (GaN channel HEMTs) are investigated. The obtained electron saturation velocity was 4.7 × 106 cm/s and the cutoff frequency was 7 GHz in the AlGaN channel HEMTs with a gate length of 1 μm. These results are promising for several gigahertz band operations of AlGaN channel HEMTs.

Authors: Mizugaki Y. , Takahashi Y. , Shimada H. , Maezawa M. 
Published: October 2014

The design and operation of a 9 bit superconductive single‐flux‐quantum (SFQ) digital‐to‐analogue converter (DAC) are presented. The DAC comprises a 9 bit variable SFQ pulse number multiplier and a 100‐fold voltage multiplier. An SFQ pulse‐frequency modulation technique is employed for coding the analogue output voltage. The DAC is fabricated using an Nb Josephson integration technology. Its output voltage waveform, the amplitude of which is up to 2.54 mVpp, is controlled by digital input signals from a room‐temperature data generator.
Strain variation measurement with short‐time Fourier transform‐based Brillouin optical time‐domain reflectometry sensing system
Authors: Tu Guojie , Zhang Xuping , Zhang Yixin , Ying Zhoufeng , Lv Lidong 
Published: October 2014

A novel technique to perform dynamic strain measurement with a Brillouin optical time‐domain reflectometry (BOTDR) sensing system based on short‐time Fourier transform (STFT) is proposed. Unlike traditional frequency scanning methods, the proposed system samples the Brillouin backscattering signal directly after it has been downconverted to the intermediated frequency (IF) region. The Brillouin frequency shift (BFS) of the sensing fibre was reconstructed from the recorded time‐domain data continuously without dead‐time, which provided a much higher refreshing rate of the strain measurement. Therefore, dynamic strain variation over an optical fibre can be measured with a single‐end structure that is more flexible and reliable. A 16.7 Hz strain variation on a 12 m section was successfully detected at the end of a 270 m sensing fibre with 4 m spatial resolution and 45 με uncertainty.
Non‐dispersive tunable reflection phase shifter based on non‐Foster circuits
Authors: Gao Fei , Zhang Fushun , Long Jiang , Jacob Minu , Sievenpiper Daniel 
Published: October 2014

A new non‐dispersive tunable reflection phase shifter is introduced based on the artificial magnetic conductor (AMC) loaded with non‐Foster circuits (NFCs). An AMC structure circuit model is extracted and the possibility of mitigating its intrinsic strong dispersion is discussed by loading it with both negative capacitance and negative inductance. The NFC is designed to produce the negative capacitance and inductance based on highly accurate, scalable measurement‐based models, and co‐simulated with a realistic model of the AMC. The numerical results are in good agreement with the analysis and show a nearly flat reflection phase from 450 to 600 MHz. This flat reflection phase can further be tuned by tuning the loaded inductance from 30 to 50 nH. This investigation paves the way towards a dispersion‐less reflection phase shifter design.
Ka‐band circularly polarised omnidirectional antenna for wide elevation coverage
Authors: Verma P.K. , Kumar R. , Singh M. 
Published: October 2014

The design, development and characterisation of an inclined waveguide slot‐based circularly polarised (CP) omnidirectional antenna at Ka‐band frequency are described. The antenna consists of inclined slots on a circular waveguide and a coaxial feeding probe. All the radiating slots are fed by the TM01 mode of the circular waveguide to generate the omnidirectional pattern. Inclination of slots has been used to generate circular polarisation. The designed antenna has omni coverage in the azimuthal plane and −10° to +45° coverage in the elevation plane. The antenna has been simulated on finite element method‐based ANSYS high‐frequency structure simulator (HFSS) EM simulator software using proper boundary conditions. The proposed antenna has the advantages of being robust, having wide coverage, being easy to fabricate (being in waveguide configuration) and is suitable for mass production. The measured axial ratio lies well below 2.8 over the horizontal plane. A voltage standing wave ratio of 2.0:1 has been achieved over the frequency band of 37.9–38.55 GHz and the minimum omni gain of the antenna is 0 dBi over the frequency band as well as over the coverage.
Magnetically coupled high‐gain Y‐source isolated DC/DC converter
Authors: Siwakoti Yam P. , Loh Poh Chiang , Blaabjerg Frede , Town Graham E. 
Published: October 2014

A new form of magnetically coupled DC/DC converter is proposed for medium power applications (250 W to 2 kW), requiring a high‐voltage gain, short inductive charging time and galvanic isolation. The proposed converter can be realised using a unique Y‐source impedance network and a two‐switch push–pull circuit with voltage‐doubling rectification. The converter's voltage gain is presently not matched by any other converter operating at the same switch duty ratio. The converter also has more degrees of freedom in design for setting the desired gain than other converters, and hence can better meet the demands of many applications. The operating principles of the converter have been analysed mathematically, and are verified by both simulation and experiment.
Evaluation of current stresses in nine‐switch energy conversion systems
Authors: Qin Zian , Loh Poh Chiang , Bahman Amir Sajjad , Blaabjerg Frede 
Published: October 2014

Converters with reduced‐switch counts usually face some performance tradeoffs, which make them suitable for some applications but not others. The same applies to the nine‐switch converter, which is a reduced‐switch version of the back‐to‐back twelve‐switch converter. The nine‐switch converter has since been shown to experience a higher voltage stress, which can be lowered in some cases. A corresponding evaluation of its current stress is however lacking, and is hence addressed now by computing its switch currents when used for ac–ac, ac–dc, dc–ac and dc–dc energy conversions. Relevant expressions, application requirements and simulation results are presented for identifying cases, where the nine‐switch converter can have an improvement in performance despite its reduced‐switch count. These cases are verified in experiments using a 1.5 kW prototype built in the laboratory.
New harmonic mitigation scheme for modular multilevel converter – an experimental approach
Authors: Sreedhar Madichetty , Dasgupta Abhijit , Mishra Sambeet 
Published: October 2014

The multilevel converter has been brought into limelight in this study; however, particular attention has been provided to the form and function of modular multilevel converter (MMC) with new controller to mitigate the circulating currents and harmonics present in the system. Till date, research in this field is very limited with circulating currents and harmonics as the major problem. The stability analysis of proposed controller has been derived and analysed with its experimental results. The system is examined before and after application of controller and results is analysed. This article effectively addresses the problem with prototype of 1 KVA implementation and attempts to make a detailed analysis with their functions in comprehensive manner with HVDC application under different conditions. Also, the applicability of zero voltage switching at turn on, zero current transition at turn off has been verified experimentally. Computer simulations and experiment on a 50 Hz power supply show that the new controller is effective and easy to implement for modular multilevel inverters.
Highly cooperative stress relaxation in two-dimensional soft colloidal crystals

Published: October 2014

Significance
The creation, annihilation, and diffusion of defects in crystal lattices play an important role during crystal melting and deformation. Although it is well understood how defects form and react when crystals are subjected to external stresses, it remains unclear how crystals cope with internal stresses. We report a study in which we create a highly localized internal stress in a crystal formed from micrometer-sized colloidal spheres and directly observe how the solid reacts using microscopy. We find that, even though the excitation is highly localized, a collective dance of colloidal particles results, even when the excitations are thermally driven. These data shed light on the importance of highly collective motions on the stability and instability of crystalline solids.

Significance
Understanding the interdependency of physiochemical properties of nanomedicine (NM) in correlation to its biological response and function is crucial for additional development of anticancer NM. Here, we prepared monodisperse drug–silica nanoconjugates in three distinct sizes (20, 50, and 200 nm) with other physiochemical properties controlled to be identical to investigate size-dependent biodistribution, tumor tissue penetration and clearance, and anticancer efficacy in various tumor models. We also developed a mathematical model of the spatiotemporal distribution of NM within a tumor to gain insight into the size-dependent interaction with tumor. Our studies show clear evidence that there is an optimal size of anticancer NM and that NM with the optimal size has the highest tumor retention integrated over time.
Traditional and Fermented Soybean Meals as Ingredients in Feeds for White Seabass and Yellowtail Jack
Authors: Trushenski Jesse T , Rombenso Artur N , Page Michael , Jirsa David , Drawbridge Mark 
Published: October 2014

Abstract
Soybean meal is commonly used as a protein source in aquafeeds, but its benefits can be limited by its digestibility and the presence of antinutritional factors. Fermentation may address both of these issues, thereby improving utilization of soybean meal by carnivorous fish. We compared the production performance of juvenile White Seabass Atractoscion nobilis and Yellowtail Jack Seriola lalandi that were fed diets containing fish meal, or graded levels of traditional soybean meal or fermented soybean meal. These diets were also compared to reduced or fish-meal-free feeds based on soy protein concentrate, poultry byproduct meal, or algal meal (spirulina Spirulina spp.). Complete fish meal replacement yielded poor performance in both species, regardless of the alternative protein source used. White Seabass performed well on diets containing blends of fish meal and traditional or fermented soybean meals or soy protein concentrate; similar results were observed in Yellowtail Jack, though performance was slightly reduced among fish fed the feed containing fermented soybean meal. These results conflict somewhat with investigations of fermented soybean meal in other fish taxa, as well as previous investigations of poultry byproduct meal and spirulina algal meal in White Seabass and Yellowtail Jack. Each of these feedstuffs has potential as a protein source in aquafeeds but presents limitations which must be addressed.
The Lack of Effectiveness of Rosemary Oil on Fish Feed in Controlling Bacterial Cold-Water Disease in Rainbow Trout
Authors: Glenn Richard A , Gannam Ann L , LaPatra Scott E 
Published: October 2014

Abstract
Rosemary Rosmarinus officinalis oil has shown potential for use as a phytobiotic fish feed supplement with antioxidant properties that can inhibit the growth of Flavobacterium psychrophilum, the pathogen that causes bacterial cold-water disease (BCWD). To determine the in vivo effectiveness of rosemary oil in preventing or minimizing BCWD, Rainbow Trout Oncorhynchus mykiss were fed commercial feed top-coated with one of two concentrations of rosemary oil (1% or 3% of the feed) or a control diet for 14 d. Fish from each feed treatment were then challenged with one of two doses of F. psychrophilum via subcutaneous injection, and mortality was monitored for 28 d. In both F. psychrophilum challenges, fish treated with feed coated with rosemary oil at the 1% and 3% levels experienced significantly higher mortality than fish treated with only soybean oil–coated feed. While the use of rosemary oil as a top-coat on feed increased mortality among Rainbow Trout subjected to a disease challenge in the current study, the mechanism for this result has not been established.
Physiological Responses of Yellow Perch to Hypoxia, Air Exposure, and Bleeding
Authors: Cnaani Avner , Hallerman Eric M , McLean Ewen 
Published: October 2014

Abstract
The North American Yellow Perch Perca flavescens is a promising candidate species for aquaculture. To evaluate potential problems resulting from husbandry practices, we measured changes in the levels of blood glucose, pH, pO2, pCO2, hematocrit, Na+, K+, Ca2+, and Cl− in response to hypoxia, blood withdrawal, and exposure to air at five time intervals over 24 h. Results were examined against resting or baseline values. Hypoxic conditions induced significant decreases in blood pH, pO2, and Na+ concentration and increases in K+, blood glucose, and hematocrit. Bleeding led to significant decreases in blood Na+, Cl−, and hematocrit and a nearly five-fold increase in blood glucose. Blood pH, pO2, and hematocrit decreased and pCO2, K+, and glucose decreased at 2 h after air exposure, were over-compensated for at 6 h, and returned slowly to levels near baseline through 24 h; Na+ and Ca2+ concentrations decreased and remained low through 24 h. Further research defining responses to culture practices and correlations with growth rate, disease resistance, and other critical traits in Yellow Perch is warranted. Our findings suggest that commercial production would benefit from adoption of practices that minimize disturbance to cultured Yellow Perch, as well as development of culture stocks more tolerant of culture conditions.

Published: October 2014

Pulmonary hypertension (PH) is defined by the presence of a mean pulmonary artery pressure (mPAP) ≥25 mmHg. It may be idiopathic or arise as a consequence of a number of diverse conditions. PH has been reported in association with POEMS syndrome (polyneuropathy, organomegaly, endocrinopathy, monoclonal plasma cell disorder, and skin changes), with reversal following systemic treatment with corticosteroids. We report a case of pulmonary hypertension associated with POEMS syndrome treated with radical radiotherapy locally to bone lesions with resolution of systemic disease.
Addition of Sodium Stearoyl Lactylate to Corn and Sorghum Starch Extrudates Enhances the Performance of Pregelatinized Beer Adjuncts

Published: October 2014

ABSTRACTDouble mashing for wort production is a time‐consuming process that can be reduced if pregelatinized adjuncts are used. Optimal extruding conditions were determined to obtain brewing adjuncts from corn and sorghum starch. For corn starch extrusion, a Box–Behnken design was devised in which moisture, screw speed, temperature of the barrel, and concentrations of sodium stearoyl lactylate (SSL) were varied, and sorghum starch was extruded according to a 23 model in which the modified variables were moisture, SSL concentration, and temperature. The aim was to maximize starch damage and minimize resistant starch and final viscosity as determined with a Rapid Visco Analyzer. The treatments that satisfied these requirements were mashed, and wort extract yield was determined. Glucose, maltose, and maltotriose concentrations in the resulting worts were determined by HPLC with a refractive index detector. Feedstock tempering and SSL content were the most important factors affecting the response; for corn starch, treatments with lower moisture (20%) and middle levels of SSL (0.5%) or with high levels of both moisture (40%) and SSL (1%) produced the most desirable samples for mashing, whereas for sorghum starch the best treatment was tempering to 20% moisture and containing middle levels of SSL (0.5%). No statistical differences were found between these experimental treatments and the control.

ABSTRACTObjectives:Nonalcoholic fatty liver disease (NAFLD), the most common cause of liver disease among US children, may be associated with cardiovascular disease (CVD) risk. The present study sought to determine the prevalence of dyslipidemia in children with NAFLD and assess dyslipidemia by liver histology and histologic changes.Methods:Individuals in the Treatment of NAFLD in Children (TONIC) trial were included (N = 173). In the TONIC trial, children with NAFLD were randomized to vitamin E, metformin, or placebo for 96 weeks. Nonalcoholic steatohepatitis (NASH) improved in 56 children. Change in lipid levels from baseline and 96 weeks was compared between patients with and without histologic improvement and with and without NASH.Results:Dyslipidemia was frequent, with low high‐density lipoprotein (HDL) (<40 mg/dL) in 61.8%, hypertriglyceridemia (≥130 mg/dL) in 50.3%, hypercholesterolemia (≥200 mg/dL) in 23.7%, elevated low‐density lipoprotein (LDL) (≥130 mg/dL) in 21.5%, elevated non‐HDL cholesterol (non‐HDL‐C) (≥145 mg/dL) in 35.2%, and triglycerides/HDL >3.0 in 57.2% of patients. Histologic improvement was associated with significant decreases in cholesterol (−11.4 mg/dL vs −1.9 mg/dL, P = 0.04), LDL (−11.2 mg/dL vs −2.1 mg/dL, P = 0.04), and non‐HDL‐C (−8.8 mg/dL vs 0.5 mg/dL, P = 0.03) compared with those without improvement. Children with NASH resolution had significant decreases in cholesterol (−10.0 mg/dL vs −0.9 mg/dL, P = 0.02) and non‐HDL‐C (−7.3 mg/dL vs 1.1 mg/dL, P = 0.01) compared with those without NASH resolution. There was no improvement in triglycerides, HDL level, or triglycerides/HDL ratio in either group.Conclusions:Dyslipidemia is frequent in children with NAFLD. NASH resolution and histologic improvement are associated with improvements in some forms of dyslipidemia.
