Leptocneria vinarskii sp. nov. (Lepidoptera: Erebidae: Lymantriinae), an overlooked Wallacean lineage of the Australian genus
Authors: Bolotov Ivan N. , Kondakov Alexander V. , Spitsyn Vitaly M. , Gofarov Mikhail Yu. , Kolosova Yulia S.
Published: September 2017

The tussock moth genus Leptocneria Butler, 1886 (Lepidoptera: Erebidae: Lymantriinae) has been considered an entirely Australian taxon that includes two species: L. reducta (Walker, 1855) and L. binotata Butler, 1886. However, we discovered a divergent lineage of Leptocneria inhabiting Flores Island, Lesser Sundas, Indonesia. Here, we describe this lineage as the third species of the genus, L. vinarskii Bolotov, Kondakov et Spitsyn sp. nov. The new species is sister to L. reducta but differs from it by dark gray marking patterns of the forewing that lack orange or dark yellow marks. The mean COI genetic distance between L. vinarskii sp. nov. and L. reducta sensu lato is 2.9%. Our findings confirm that the Wallacean region was a faunal exchange area between Sundaland and Sahul during the Pleistocene but highlight that the vicariance events may have played a crucial role in origin of the endemic faunas on the islands of East Nusa Tenggara. Additionally, we show that both Australian species most likely represent cryptic species complexes, which are in need of further taxonomic revision.
A New Family of Multilevel Grid Connected Inverters Based on Packed U Cell Topology
Authors: Pakdel Majid , Jalilzadeh Saeid
Published: September 2017

In this paper a novel packed U cell (PUC) based multilevel grid connected inverter is proposed. Unlike the U cell arrangement which consists of two power switches and one capacitor, in the proposed converter topology a lower DC power supply from renewable energy resources such as photovoltaic arrays (PV) is used as a base power source. The proposed topology offers higher efficiency and lower cost using a small number of power switches and a lower DC power source which is supplied from renewable energy resources. Other capacitor voltages are extracted from the base lower DC power source using isolated DC-DC power converters. The operation principle of proposed transformerless multilevel grid connected inverter is analyzed theoretically. Operation of the proposed multilevel grid connected inverter is verified through simulation studies. An experimental prototype using STM32F407 discovery controller board is performed to verify the simulation results.

Authors: Kim Hong Jae , Tak Young Jun , Park Sung Pyo , Na Jae Won , Kim Yeong-gyu , Hong Seonghwan , Kim Pyeong Hun , Kim Geon Tae , Kim Byeong Koo , Kim Hyun Jae
Published: September 2017

In this study, we propose a self-activated radical doping (SRD) method on the catalyzed surface of amorphous oxide film that can improve both the electrical characteristics and the stability of amorphous oxide films through oxidizing oxygen vacancy using hydroxyl radical which is a strong oxidizer. This SRD method, which uses UV irradiation and thermal hydrogen peroxide solution treatment, effectively decreased the amount of oxygen vacancies and facilitated self-passivation and doping effect by radical reaction with photo-activated oxygen defects. As a result, the SRD-treated amorphous indium-gallium-zinc oxide (a-IGZO) thin film transistors (TFTs) showed superior electrical performances compared with non-treated a-IGZO TFTs. The mobility increased from 9.1 to 17.5 cm2/Vs, on-off ratio increased from 8.9 × 107to 7.96 × 109, and the threshold voltage shift of negative bias-illumination stress for 3600 secs under 5700 lux of white LED and negative bias-temperature stress at 50 °C decreased from 9.6 V to 4.6 V and from 2.4 V to 0.4 V, respectively.

X-shooter observations of low-mass stars in theηChamaeleontis association
Authors: Rugel Michael , Fedele Davide , Herczeg Gregory
Published: September 2017

The nearbyηChamaeleontis association is a collection of 4–10 Myr old stars with a disk fraction of 35–45%. In this study, the broad wavelength coverage of VLT/X-shooter is used to measure the stellar and mass accretion properties of 15 low-mass stars in theηChamaeleontis association. For each star, the observed spectrum is fitted with a non-accreting stellar template and an accretion spectrum obtained from assuming a plane-parallel hydrogen slab. Five of the eight stars with an IR disk excess show excess UV emission, indicating ongoing accretion. The accretion rates measured here are similar to those obtained from previous measurements of excess UV emission, but tend to be higher than past measurements from Hαmodeling. The mass accretion rates are consistent with those of other young star forming regions.
Sodium abundances of AGB and RGB stars in Galactic globular clusters
Authors: Wang Y. , Primas F. , Charbonnel C. , Van der Swaelmen M. , Bono G. , Chantereau W. , Zhao G.
Published: September 2017

Aims. We investigate the Na abundance distribution of asymptotic giant branch (AGB) stars in Galactic globular clusters (GCs) and its possible dependence on GC global properties, especially age and metallicity.

Methods. We analyze high-resolution spectra of a large sample of AGB and red giant branch (RGB) stars in the Galactic GCs NGC 104, NGC 6121, and NGC 6809 obtained with FLAMES/GIRAFFE at ESO/VLT, and determine their Na abundances. This is the first time that the AGB stars in NGC 6809 are targeted. Moreover, to investigate the dependence of AGB Na abundance dispersion on GC parameters, we compare the AGB [Na/H] distributions of a total of nine GCs, with five determined by ourselves with homogeneous method and four from literature, covering a wide range of GC parameters.

Results. NGC 104 and NGC 6809 have comparable AGB and RGB Na abundance distributions revealed by the K−S test, while NGC 6121 shows a lack of very Na-rich AGB stars. By analyzing all nine GCs, we find that the Na abundances and multiple populations of AGB stars form complex picture. In some GCs, AGB stars have similar Na abundances and/or second-population fractions as their RGB counterparts, while some GCs do not have Na-rich second-population AGB stars, and various cases exist between the two extremes. In addition, the fitted relations between fractions of the AGB second population and GC global parameters show that the AGB second-population fraction slightly anticorrelates with GC central concentration, while no robust dependency can be confirmed with other GC parameters.

Conclusions. Current data roughly support the prediction of the fast-rotating massive star (FRMS) scenario. However, considering the weak observational and theoretical trends where scatter and exceptions exist, the fraction of second-population AGB stars can be affected by more than one or two factors, and may even be a result of stochasticity.

Results: The five selected best papers present studies with rigorous methods, properly designed and described and are, therefore, efficiently reusable for other researches.

Conclusion: Human factors and ergonomics- based interventions must be tailored to the context, but meaningful ways must be simultaneously found to generate a stronger evidence base for research and to provide efficient, easy to implement, and useful methods.
Secondary Use of Recorded or Self-expressed Personal Data: Consumer Health Informatics and Education in the Era of Social Media and Health Apps
Authors: Staccini P. , Fernandez-Luque L.
Published: September 2017

Objective: To summarize the state of the art during the year 2016 in the areas related to consumer health informatics and education with a special emphasis in secondary use of patient data.

Methods: We conducted a systematic review of articles published in 2016, using PubMed with a predefined set of queries. We identified over 320 potential articles for review. Papers were considered according to their relevance for the topic of the section. Using consensus, we selected the 15 most representative papers, which were submitted to external reviewers for full review and scoring. Based on the scoring and quality criteria, five papers were finally selected as best papers

Results: The five best papers can be grouped in two major areas: 1) methods and tools to identify and collect formal requirements for secondary use of data, and 2) innovative topics highlighting the interest of carrying on “secondary” studies on patient data, more specifically on the data self-expressed by patients through social media tools. Regarding the formal requirements about informed consent, the selected papers report a comparison of legal aspects in European countries to find a common and unified grammar around the concept of “data donation”. Regarding innovative approaches to value patient data, the selected papers report machine learning algorithms to extract knowledge from patient experience and satisfaction with health care delivery, drug and medication use, treatment compliance and barriers during cancer disease, or acceptation of public health actions such as vaccination.

Conclusions: Secondary use of patient data (apart from personal health care record data) can be expressed according to many ways. Requirements to allow this secondary use have to be harmonized between countries, and social media platforms can be efficiently used to explore and create knowledge on patient experience with health problems or activities. Machine learning algorithms can explore those massive amounts of data to support health care professionals, and institutions provide more accurate knowledge about use and usage, behaviour, sentiment, or satisfaction about health care delivery.
The Role of Free/Libre and Open Source Software in Learning Health Systems
Authors: Paton C. , Karopka T.
Published: September 2017

Objective: To give an overview of the role of Free/Libre and Open Source Software (FLOSS) in the context of secondary use of patient data to enable Learning Health Systems (LHSs).

Methods: We conducted an environmental scan of the academic and grey literature utilising the MedFLOSS database of open source systems in healthcare to inform a discussion of the role of open source in developing LHSs that reuse patient data for research and quality improvement.

Results: A wide range of FLOSS is identified that contributes to the information technology (IT) infrastructure of LHSs including operating systems, databases, frameworks, interoperability software, and mobile and web apps. The recent literature around the development and use of key clinical data management tools is also reviewed.

Conclusions: FLOSS already plays a critical role in modern health IT infrastructure for the collection, storage, and analysis of patient data. The nature of FLOSS systems to be collaborative, modular, and modifiable may make open source approaches appropriate for building the digital infrastructure for a LHS.
A Single-Center Experience with Dynamic Compression Bracing for Children with Pectus Carinatum
Authors: Poola Ashwini , Pierce Amy , Orrick Beth , Peter Shawn , Snyder Charles , Juang David , Aguayo Pablo , Fraser Jason , Holcomb George
Published: September 2017

Objective Bracing for pectus carinatum (PC) has emerged as an alternative to surgical correction. However, predictive factors for bracing remain poorly understood, as much of the data have been reported from small series.

Materials and Methods We reviewed a prospective dataset in patients with PC who underwent dynamic compression bracing (DCB) from July 2011 to July 2016. Bracing was initiated in patients > 10 years of age with a significant PC and desire for bracing. Data were analyzed for those observed two or more times after the brace was fitted to the patient.

Results A total of 503 patients were evaluated for PC and 340 (68%) underwent DCB. Eighty-five percent were males with an average age of 14 ± 2 years. There was a positive correlation of age with pressure of initial correction (PIC, r = 0.2). One patient underwent operative correction as the initial therapy. Two hundred seventeen patients had two or more visits after the patient was fitted for the brace. The mean PIC in this cohort was 4 psi (range: 1.5–7.8), and the median duration of bracing in this group was 16 months (IQR: 7–23 months). One hundred three patients (47%) achieved complete correction after an average bracing time of 7.5 months and were then placed in the retainer mode. Thirty patients successfully completed bracing therapy and required an average of 23 months of therapy (2 months–4 years). No patient recurred after bracing was completed, but one failed bracing and required operative correction. Complications included mechanical problems (8%), skin complications (10%), complaints of tightness (3%), and pain (2%).

Conclusion DCB has both early and lasting effects in the correction of PC with minimal complications. Predictive factors for successful resolution of the PC include increased duration of DCB and lower initial PIC.

Published: September 2017

Introduction Acute appendicitis is the most common emergency condition in pediatric surgery. Historically, a triple-antibiotic therapy consisted of ampicillin, gentamicin, and clindamycin has been used postoperatively for perforated appendicitis. According to recently published trials, dual therapy consists of ceftriaxone and metronidazole only, offers a more efficient and cost-effective antibiotic management compared with triple therapy. Based on these results, our department applied dual antibiotic therapy for children with perforated appendicitis that underwent appendectomy from 2009 and forth.

Aim The aim of our study was to compare postoperative outcomes between patients treated with triple therapy (ampicillin, gentamicin, and metronidazole) (group A) versus dual therapy (ceftriaxone and metronidazole) (group B).

Methods Clinical and laboratory data were retrospectively collected by review of the medical records for all children who underwent appendectomy for the perforated appendix at the Schneider Children's Medical Center of Israel, a tertiary pediatric care center between 2007 and 2011. Children with perforated appendicitis received antibiotic therapy in accordance with the hospital's guidelines that were valid at the time the surgery took place. In the first period (years 2007–2009) (group A) a triad of ampicillin, gentamicin, and metronidazole and the second period (2009–2011) (group B) dual therapy consists of ceftriaxone and metronidazole. The two groups were compared for outcome and complications, such as wound infections, changing of antibiotic therapy, and length of stay.

Results During the study period 1,203 patients underwent an appendectomy. Of these, 175 patients were diagnosed with perforated appendix and were treated with postoperative antibiotic's regimen. Group A and group B consisted of 89 and 86 patients, respectively. The two groups were not different significantly in terms of demographic data, length of stay, or readmission rates. However, more rates of wound infection and changing of antibiotic therapy were seen in group B, although not statistically significant (p = 0.064).

Conclusion Dual antibiotic therapy for perforated appendicitis is a cost-effective and efficient mode of therapy compared with triple-antibiotic's regimen. However, prospective studies are required to determine whether this policy is associated with higher rates of wound infections and change in antibiotic therapy.

Italian pediatric surgery has a long history, rich in events, places, and personalities that make it unique. Our first pediatric surgical unit dates back to the first half of the 19th century and its number has grown exponentially during the following decades, with a maximum flowering in the years after the second world war.

The rich history of pediatric surgery has not prevented it from facing important problems, such as the demographic crisis, underemployment of surgeons, and care of pediatric patients by adult specialists.

The attempt to find solutions to these problems has led to a great deal of efforts not only by pediatric surgeons, but also by the Italian government and institutions, with the implementation of ministerial plans that favor the specificity and growth of our discipline through thematic and territorial networks, through more effective training and specialization plans, the cooperation between the Directors of Pediatric Surgical Units for a better coordination of care, the participation in European networks, such as the recently created ERNs (European Reference Networks).

Many Italian pediatric surgeons are active in International Societies, as members or coordinators, in the design and management of multicenter studies and surveys and even in the creation of new international networks.

The Italian response to the demand for specialization and centralization involves knowledge sharing, large-scale cooperation, transversal between specialists and vertical with governmental authorities for a better and more effective care of pediatric patients.

Background The incidence of invasive aspergillosis (IA) in children with hematooncological malignancies is increasing as a result of intensive treatment, immunosuppression, and extended use of broad-spectrum antibiotics. Infection of the GI tract by Aspergillus spp. is a rare and fatal complication, which often requires surgical diagnostic and therapeutic exploration.

Objective The aim of this study was to determine the characteristics of symptomatic intestinal aspergillosis, diagnosis, treatment, and outcome of pediatric patients with an underlying hemato-oncologic disease.

Patients and Methods We analyzed 2,307 German patients with acute lymphoblastic leukemia (ALL) from age 1 to 17 years registered in the AIEOP-BFM ALL 2000 study from 2000 to 2006. All reported adverse events were assessed for symptoms of IA and retrospectively reviewed for any sign or proof of intestinal involvement of IA.

Results In this cohort, IA was reported in 30 of 2,307 patients while intestinal involvement was documented in five patients. Four of these patients had intestinal symptoms and three patients underwent explorative laparotomy. Among clinical cases with IA, gastrointestinal manifestation of IA mostly occurred in adolescent patients (10–16 years). Symptoms varied from abdominal tenderness and pain to constipation. Intestinal aspergillosis was proven by microbiological and histopathological examination and fungal infection was observed macroscopically in the jejunal lumen during surgery. Despite the extended surgery and antifungal therapy, outcome of disseminated IA with intestinal involvement remains poor.

Conclusion Surgeons should be aware of surgical complications of intestinal aspergillosis in children with hematooncological diseases requiring exploration and resection. IA is a rare event and still difficult to diagnose due to unspecific abdominal symptoms. Thus, biopsy sampling is of utmost importance to ensure diagnosis, and resection of necrotic or perforated tissue should be attempted early.
Duplex Sonographic Diagnosis of Perinatal Hemorrhagic Stroke
Authors: Deeg Karl-Heinz
Published: September 2017

Children are particularly at risk for stroke in the neonatal period. Neonatal hemorrhagic stroke is rarer than ischemic stroke. The incidence is 40.7/100 000 live births. Hemorrhagic stroke is caused by a disruption in venous drainage usually due to local thrombosis. As a result of the nonspecific clinical symptoms in this age group, diagnosis is usually made too late. The only relatively specific symptom is a cerebral seizure during the first week of life. Therefore, stroke should be ruled out by diagnostic imaging in the case of any seizure in the first days of life. The diagnostic method of choice is MRI, but it is not always available. Most neonatal strokes can be detected with high-resolution duplex ultrasound. Hemorrhagic stroke appears as a focal increase in echogenicity in a venous drainage area on ultrasound. The corresponding venous drainage can be visualized with duplex ultrasound and measured with spectral Doppler. Hemorrhagic stroke of the internal veins appears as hemorrhage in the basal ganglia. Venous thrombosis must be ruled out in every cerebral hemorrhage of unclear origin in an otherwise healthy term newborn. In the case of hemorrhagic infarction of the basal ganglia, both internal cerebral veins, the great vein of Galen, and the straight sinus must be examined with Doppler ultrasound. Doppler ultrasound should be used to differentiate between complete occlusion and severe stenosis. The recanalization of vessels and the morphological consequences of hemorrhagic stroke can be visualized in the further course.
Effect of electron inertia on dispersive properties of Alfvén waves in cold plasmas

Published: September 2017

The effect of electron inertia on Alfvén wave propagation is investigated in the framework of the two-fluid theory in a compressible magnetized plasma. The linear analysis of the governing equations manifests the dispersion relation of the circularly polarized Alfvén waves where the electron inertia is found to act as a source of dispersion. In the finite amplitude limit, the nonlinear Alfvén wave may be described by the Derivative Nonlinear Schrödinger equation (DNLSE) modified by third order dispersion arising due to finite electron inertia. The derived equation seems to be novel with respect to what exists in the literature of Alfvén wave dynamics. We have shown that this electron inertia modified DNLSE is completely integrable and an analytical solution is demonstrated with vanishing boundary conditions. The results are expected to be of special importance in the context of space and laboratory plasmas.
Quantum engineering of superconducting structures: Principles, promise and problems
Authors: Zagoskin Alexandre
Published: September 2017

Quantum technologies went through an explosive development since the beginning of the century. The progress in the field of superconducting quantum structures was especially fast. As the result, the design and characterization of large quantum coherent structures became an engineering problem. We will discuss the current status of the emerging discipline of quantum engineering and possible ways of meeting its main challenge, the fundamental impossibility of an efficient modelling of a quantum system using classical means.

Published: September 2017

We present the results of an analytical study and numerical simulation of the dynamics of a superconducting three-Josephson-junction (3JJ) flux qubit magnetically coupled with rapid single-flux quantum (RSFQ) logic circuit, which demonstrate the fundamental possibility of implementing the simplest logic operations at picosecond times, as well as rapid non-destructive readout. It is shown that when solving optimization problems, the qubit dynamics can be conveniently interpreted as a precession of the magnetic moment vector around the direction of the magnetic field. In this case, the role of magnetic field components is played by combinations of the Hamiltonian matrix elements, and the role of the magnetic moment is played by the Bloch vector. Features of the 3JJ qubit model are discussed during the analysis of how the qubit is affected by exposure to a short control pulse, as are the similarities between the Bloch and Landau-Lifshitz-Gilbert equations. An analysis of solutions to the Bloch equations made it possible to develop recommendations for the use of readout RSFQ circuits in implementing an optimal interface between the classical and quantum parts of the computer system, as well as to justify the use of single-quantum logic in order to control superconducting quantum circuits on a chip.

Published: September 2017

We present the results of numerical study of the phase dynamics of the dc SQUID with topologically trivial and nontrivial barriers. In our calculations we take into account two components of superconducting current, Cooper pairs (2π periodic) and Majorana fermions (4π periodic) currents. Magnetic field dependence of return current is presented. The qualitative behavior of this dependence is explained. We show that in case of two-component superconducting current the periodicity of magnetic field dependence of return current displaced by Cooper pairs and Majorana fermion ratio over the magnetic field. This effect makes possible the experimental determination of ratio of Cooper pairs and Majorana fermions currents.
Pseudogap and fluctuation conductivity in Y1-xPrxBa2Cu3O7-δ single crystals with different concentrations of praseodymium

The effects of praseodymium doping on the excess conductivity σ′(T) and pseudogap (PG) Δ*(T) in Y1–xPrxBa2Cu3O7–δ single crystals with a change in the Pr concentration from x = 0 to x = 0.43 are presented. It is found that as x increases the resistance of the samples increases, whereas the critical temperature Tc drops. At the same time the shape of the ρ(T) curves changes from metallic (x ≤ 0.34) to one that is typical for weakly doped YBa2Cu3O7–δ single crystals with a characteristic thermally activated deflection (x > 0.34). Regardless of the value of x, close to Tc, σ′(T) is well described by the Aslamazov-Larkin and Maki-Thompson theories, demonstrating a 3D-2D crossover with increasing temperature. The crossover temperature T0 makes it possible to determine the coherence length along the c axis, ξc(0). At x = 0, Δ*(T) displays a maximum at Tpair ≈ 110 К that is typical for YBCO films. As x increases the maximum at Tpair is washed out, but a pronounced maximum Δ*(T) in the high temperature region appears, followed by a linear section with a positive slope. Such a dependence Δ*(T) is normal for magnetic superconductors and is, most likely, caused by the influence of the intrinsic magnetic moment of Pr (μPr ≈ 4μB).
Resonant transparency of a photonic crystal containing layered superconductor as a defect

Published: September 2017

Transmission of a TM-polarized terahertz wave through a 1D photonic crystal of finite thickness containing a defect consisting of a layered-superconductor plate with the superconducting layers orthogonal to the layers of the photonic crystal is studied theoretically. An analytical expression for the transmittance is derived. It is shown that the transparency in the band gap of the photonic crystal can be significantly enhanced due to the resonant excitation of the modes localized on the defect.

Published: September 2017

The effect of Cu alloying on the deformation behavior of Mo thin films is investigated as a feasible concept to overcome their poor ductility, which severely limits performance in flexible electronics. 50 nm thick Mo1-xCux films (with 0 ≤ x ≤ 0.51) were sputter-deposited on polyimide substrates and subjected to uniaxial tensile loading while measuring their electrical resistance in situ. A significant ductility enhancement is experimentally observed with increasing Cu content. This can be rationalized by considering the associated changes in bond character as the Cu additions weaken the covalent and hence shear resistant contribution to the overall bond character.
New multipactor dynamics in presence of dielectrics
Authors: Sorolla E. , Belhaj M. , Sombrin J. , Puech J.
Published: September 2017

A new multipactor saturation mechanism is presented for high power microwave devices in the presence of dielectrics. Recent measures have shown that the positive charge deposited on a dielectric as a consequence of the secondary electron emission causes the reduction of its secondary electron yield. This work shows a new multipactor dynamics within a partially filled parallel-plate waveguide where both the decrease of the secondary electron yield with the charge on the dielectric and the subsequent electrostatic field produced are taken into account. The results obtained show that these two mechanisms predict the multipactor saturation as well as some differences with the classical resonance theory when charged dielectrics come into play.
