Resistive switching in manganese oxide with nonlineardependence of the local resistivity on the oxygen‐vacancy concentration
Authors: Boylo Irina V. 
Published: February 2017

AbstractThe present paper examines the influence of a nonlinear relationship between the local oxygen‐vacancy concentration and the local resistivity on resistive switching effects in complex oxides. The continuity equation has been used as a model for the motion of oxygen vacancies when a periodic time‐dependent electrical current is applied. The question of endurance of the switching cycles is discussed. It is found that nonlinearity of the resistivity–concentration dependence enhances the endurance.
Coupled cluster calculations provide a one‐to‐one mapping between calculated and observed transition energies in the electronic absorption spectrum of zinc phthalocyanine
Authors: Wallace Andrew J. , Williamson Bryce E. , Crittenden Deborah L. 
Published: February 2017

AbstractAll transitions in the experimentally designated and numbered Q, B, and N bands (< 4.8 eV) of the electronic absorption spectrum of zinc phthalocyanine (ZnPc) are assigned on the basis of one‐to‐one agreement between calculated and experimentally observed transition energies and oscillator strengths. Each band in this range of the spectrum represents a ligand‐based transition that originates from a combination of occupied orbitals and terminates in the lowest unoccupied molecular orbital (LUMO,
). Transition energies in the L and C regions (4.8–6.5 eV) are harder to capture quantitatively, due to the partial Rydberg character of some of the excited states, and so are tentatively assigned here. Most transitions in this range correspond to excitations from the HOMO or lower‐energy orbitals to π orbitals above the LUMO.
The enhancing effects of molecule X (X = PH2Cl, SHCl, ClCl) on chalcogen–chalcogen interactions in cyclic trimers Y···Y···X (Y = SHCl, SeHCl)
Authors: Mo Lixin , Zeng Yanli , Li Xiaoyan , Meng Lingpeng 
Published: February 2017

AbstractThe enhancing effects of molecule X (X = PH2Cl, SHCl, ClCl) on S···S and Se···Se chalcogen–chalcogen bonds in the cyclic trimers SHCl···SHCl···X and SeHCl···SeHCl···X were investigated by calculations at the MP2/aug‐cc‐pVTZ level. When molecule X is added to the dimer SHCl···SHCl (SeHCl···SeHCl), cyclic trimers are formed. Compared with the dimer, all the cyclic trimers have shorter S···S (Se···Se) lengths, greater electron densities, negative three‐body interaction energies, and larger second‐order perturbation energies. These results indicate that the addition of molecule X strengthens the original S···S (Se···Se) bond. For the SHCl···SHCl···X cyclic trimers, the S···S bond is strongest in SHCl···SHCl···PH2Cl, weaker in SHCl···SHCl···SHCl, and weakest in SHCl···SHCl···ClCl. This same trend is observed for the Se···Se bond in SeHCl···SeHCl···X. This means that PH2Cl provides the greatest enhancement to the S···S (Se···Se) interaction.
Evaluating code‐based test input generator tools
Authors: Cseppentő Lajos , Micskei Zoltán 
Published: February 2017

SummaryIn recent years, several tools have been developed to automatically select test inputs from the code of the system under test. However, each of these tools has different advantages, and there is a little detailed feedback available on the actual capabilities of the various tools. To evaluate test input generators, this paper collects a set of programming language concepts that should be handled by the tools and maps these core concepts and challenging features like handling the environment or multi‐threading to 363 code snippets, respectively. These snippets would serve as inputs for the tools. Next, the paper presents SETTE, an automated framework to execute and evaluate these snippets. Using SETTE, multiple experiments were performed on five Java and one .NET‐based tools using symbolic execution, search‐based, and random techniques. The test suites' coverage, size, generation time, and mutation score were compared. The results highlight the strengths and weaknesses of each tool and approach and identify hard code parts that are difficult to tackle for most of the tools. We hope that this research could serve as actionable feedback to tool developers and help practitioners assess the readiness of test input generation.
BDNF‐induced endocannabinoid release modulates neocortical glutamatergic neurotransmission
Authors: Yeh Mason L. , Selvam Rajamani , Levine Eric S. 
Published: February 2017

AbstractEndocannabinoids (eCBs) and neurotrophins, particularly brain‐derived neurotrophic factor (BDNF), are potent neuromodulators found throughout the mammalian neocortex. Both eCBs and BDNF play critical roles in many behavioral and neurophysiological processes and are targets for the development of novel therapeutics. The effects of eCBs and BDNF are primarily mediated by the type 1 cannabinoid (CB1) receptor and the trkB tyrosine kinase receptor, respectively. Our laboratory and others have previously established that BDNF potentiates excitatory transmission by enhancing presynaptic glutamate release and modulating NMDA receptors. In contrast, we have shown that BDNF attenuates inhibitory transmission by inducing postsynaptic release of eCBs that act retrogradely to suppress GABA release in layer 2/3 of somatosensory cortex. Here, we hypothesized that BDNF also induces release of eCBs at excitatory synapses, which could have a mitigating or opposing effect on the direct presynaptic effects of BDNF. We found the highest levels of expression of CB1 and trkB and receptors in layers 2/3 and 5. Surprisingly, BDNF did not increase the frequency of spontaneous miniature excitatory postsynaptic currents (mEPSCs) onto layer 5 pyramidal neurons in somatosensory cortex, in contrast to its effects in the hippocampus and visual cortex. However, the effect of BDNF on mEPSC frequency in somatosensory cortex was unmasked by blocking CB1 receptors or disrupting eCB release. Thus, BDNF‐trKB signaling regulates glutamate release in the somatosensory cortex via opposing effects, a direct presynaptic enhancement of release probability, and simultaneous postsynaptically‐induced eCB release that decreases release probability via presynaptic CB1 receptors.

Published: February 2017

AbstractThis paper discusses the model‐based design of a blade pitch controller for a floating offshore wind turbine (FOWT) scale model. A mathematical model of the FOWT is constructed from an input–output measurement in an experiment using system identification. The blade pitch controller is designed by an
control method, and the effectiveness of the controller is evaluated by means of a basin experiment using the FOWT scale model. The results show that the blade pitch controller is effective in reducing platform pitch motion and rotor speed fluctuation. Copyright © 2017 John Wiley & Sons, Ltd.

Published: February 2017

AbstractBackgroundAt Ganga Hospital in Coimbatore, India, a unique approach is applied to treat massive upper limb injuries. However, long‐term outcomes of complex reconstruction performed in the resource‐limited setting are not known. This hinders understanding of outcomes and disability from these injuries and prevents systematically addressing care delivery around upper extremity trauma in the developing world. This project aims to analyze the details of the unique Ganga Hospital reconstruction experience and use patient‐reported outcome measures for the first time in this patient population to evaluate post‐injury recovery and disability.MethodsForty‐six patients were evaluated 6 months or more after massive proximal upper extremity reconstruction at Ganga Hospital. Patients completed functional tests, Jebsen–Taylor test (JTT), and patient‐reported outcomes (PROs)—Michigan Hand Questionnaire (MHQ), Disability of Arm, Shoulder, and Hand questionnaire (DASH), and Short‐Form 36 (SF‐36). Correlations between metrics were assessed with Pearson’s correlation coefficients. Linear regression modeling evaluated associations between severity, reconstruction, and outcomes.ResultsMHQ and DASH results correlated with functional test performance, JTT performance, and SF‐36 scores (Pearson’s coefficients all ≥0.33, p ≤ 0.05). In this cohort, mean MHQ score was 79 ± 15 and mean DASH score was 13 ± 15, which are not significantly different than scores for long‐term outcomes after other complex upper extremity procedures. The following factors predicted PROs and functional performance after reconstruction: extent of soft tissue reconstruction, multi‐segmental ulna fractures, median nerve injury, and ability for patients to return to work and maintain their job after injury.ConclusionsComplex proximal upper extremity salvage can be performed in the resource‐limited setting with excellent long‐term functional and patient‐reported outcomes. PRO questionnaires are useful for reporting outcomes that correlate to functional and sensory testing and may be used to assess post‐traumatic disability.

Published: February 2017

AbstractBackgroundIntraoperative identification of the difficult‐to‐spot parathyroid gland is critical during surgery for thyroid and parathyroid disease. Recently, intrinsic fluorescence of the parathyroid gland was identified, and a new method was developed for intraoperative detection of the parathyroid with an original fluorescent detection apparatus. Here, we describe a method for intraoperative detection of the parathyroid using a ready‐made photodynamic eye (PDE) system without any fluorescent dye or contrast agents.MethodsSeventeen patients who underwent surgical treatment for thyroid or parathyroid disease at Kagoshima University Hospital were enrolled in this study. Intrinsic fluorescence of various tissues was detected with the PDE system. Intraoperative in vivo and ex vivo intrinsic fluorescence of the parathyroid, thyroid, lymph nodes and fat tissues was measured and analyzed.ResultsThe parathyroid gland had a significantly higher fluorescence intensity than the other tissues, including the thyroid glands, lymph nodes and fat tissues, and we could identify them during surgery using the fluorescence‐guided method. Our method could be applicable for two intraoperative clinical procedures: ex vivo tissue identification of parathyroid tissue and in vivo identification of the location of the parathyroid gland, including ectopic glands.ConclusionThe PDE system may be an easy and highly feasible method to identify the parathyroid gland during surgery.

Published: February 2017

AbstractAs healthcare reimbursement is increasingly tied to value‐of‐service, it is critical for the genetic counselor (GC) profession to demonstrate the value added by GCs through outcomes research. We conducted a rapid systematic literature review to identify outcomes of genetic counseling. Web of Science (including PubMed) and CINAHL databases were systematically searched to identify articles meeting the following criteria: 1) measures were assessed before and after genetic counseling (pre‐post design) or comparisons were made between a GC group vs. a non‐GC group (comparative cohort design); 2) genetic counseling outcomes could be assessed independently of genetic testing outcomes, and 3) genetic counseling was conducted by masters‐level genetic counselors, or non‐physician providers. Twenty‐three papers met the inclusion criteria. The majority of studies were in the cancer genetic setting and the most commonly measured outcomes included knowledge, anxiety or distress, satisfaction, perceived risk, genetic testing (intentions or receipt), health behaviors, and decisional conflict. Results suggest that genetic counseling can lead to increased knowledge, perceived personal control, positive health behaviors, and improved risk perception accuracy as well as decreases in anxiety, cancer‐related worry, and decisional conflict. However, further studies are needed to evaluate a wider array of outcomes in more diverse genetic counseling settings.
Soziale und ethische Aspekte der personalisierten Medizin
Authors: Schallenberg Peter 
Published: February 2017

ZusammenfassungZur aristotelischen Grundnorm des guten Lebens gehört heute ohne Zweifel auch der Aspekt der physischen und psychischen Gesundheit. Das Recht auf angemessene gesundheitliche Versorgung steht jedoch nicht selten in Konflikt mit den marktwirtschaftlichen Strukturen der Postmoderne. Dazu kommt, dass die moderne Medizin mehr kann, als derzeit vorstellbar ist und als sich der Sozialstaat in Zukunft wird leisten können. So läuft scheinbar alles auf eine optimierte Lebensquantität hinaus. Demgegenüber steht die Option, wieder zu lernen, mit einer bedingten Gesundheit zu leben, da zur Lebensqualität einer Person immer auch der Umgang mit und die Bewältigung von Krankheit und Tod gehören.
Reconstructing forest canopy from the 3D triangulations of airborne laser scanning point data for the visualization and planning of forested landscapes
Authors: Vauhkonen Jari , Ruotsalainen Roope 
Published: February 2017

Abstract

Key message

We present a data-driven technique to visualize forest landscapes and simulate their future development according to alternative management scenarios. Gentle harvesting intensities were preferred for maintaining scenic values in a test of eliciting public’s preferences based on the simulated landscapes.

Context
Visualizations of future forest landscapes according to alternative management scenarios are useful for eliciting stakeholders’ preferences on the alternatives. However, conventional computer visualizations require laborious tree-wise measurements or simulators to generate these observations.

Aims
We describe and evaluate an alternative approach, in which the visualization is based on reconstructing forest canopy from sparse density, leaf-off airborne laser scanning data.

Methods
Computational geometry was employed to generate filtrations, i.e., ordered sets of simplices belonging to the three-dimensional triangulations of the point data. An appropriate degree of filtering was determined by analyzing the topological persistence of the filtrations. The topology was further utilized to simulate changes to canopy biomass, resembling harvests with varying retention levels. Relative priorities of recreational and scenic values of the harvests were estimated based on pairwise comparisons and analytic hierarchy process (AHP).

Results
The canopy elements were co-located with the tree stems measured in the field, and the visualizations derived from the entire landscape showed reasonably realistic, despite a low numerical correspondence with plot-level forest attributes. The potential and limitations to improve the proposed parameterization are discussed.

Conclusion
Although the criteria to evaluate the landscape visualization and simulation models were not conclusive, the results suggest that forest scenes may be feasibly reconstructed based on data already covering broad areas and readily available for practical applications.

Asymptotic behaviour of solutions to the Korteweg-deVries-Burgers system
Authors: Schonbek M.E. , Rajopadhye S.V. 
Published: February 2017

We consider the large time behaviour of solutions ot the Korteweg-deVries–Burgers system of equations to obtain lower and upper bounds for the rates of decay of the solution. These decay rates extend the work of Amick
et al
. [1], where the scalar case was considered and that of Zhang Linghai [8]. An important tool in the analysis is the so called Fourier Splitting method developed by M. E. Schonbek for obtaining algebraic upper bounds for the solution to the system of parabolic conservation laws. This tool was later used to establish algebraic upper and lower bounds for the Navier Stokes and Magneto Hydrodynamic equations. The lower bounds show that in the far field the behaviour of the solutions to the KdVB system and those of the heat system are very different. This behaviour is believed to be due to the nonlinearity and not to the dispersive nature of the equation, since such behaviour is also present in non-dispersive systems like the Navier-Stokes and the Magneto-Hydrodynamic equations.

tendant vers l’infini, le comportement des solutions pour les systèmes de Korteweg-deVries–Burger et le comportement des solutions de l’équation de la chaleur sont différents: ce comportement proviendrait des termes non linéaires et non de la nature dispersive du système car il est aussi présent dans des systèmes non dispersifs comme les équations de Navier–Stokes et les équations de Magnéto-Hydrodynamique.

Is Age Associated With the Severity of Post–Mild Traumatic Brain Injury Symptoms?
Authors: Hu Tina , Hunt Cindy , Ouchterlony Donna 
Published: February 2017

AbstractBackground: Mild traumatic brain injury (mTBI) is a significant public health concern. Research has shown that mTBI is associated with persistent physical, cognitive, and behavioural symptoms, leading to significant direct and indirect medical costs. Our objective was to determine if age impacts the type and severity of post-mTBI symptoms experienced. Methods: Retrospective analysis of prospectively collected data at a level 1 tertiary care outpatient head injury clinic. Participants (N=167) were patients seen at the clinic following an mTBI. The Rivermead Post-Concussion Symptoms Questionnaire was used to assess symptom severity. Results: In our sample, the mean age was 44±16 years with 51% males. Compared with other age groups, patients >66 years of age were significantly more likely to report an mTBI between 6 AM to 12 PM (69%). Middle-aged patients (36-55 years) were more likely to report higher severity of certain post-mTBI symptoms (headache, nausea and vomiting, irritability, poor concentration, sleep disturbance, blurry vision, light sensitivity, and taking longer to think) compared with patients >66 years of age. Conclusions: In general, middle-aged patients reported higher severity of post-mTBI symptoms compared with the oldest patients. Thus, there was a significant association between age and the severity of specific mTBI symptoms, which highlights the need for targeted management. Additional research is needed to understand the mechanisms that could be contributing to the higher symptom severity experienced by the middle-aged group.
