Published: June 2017

AbstractSilver nanorod arrays prepared by oblique angle deposition (AgOADs) represent versatile, simple and inexpensive substrates for high sensitivity surface enhanced Raman scattering (SERS) applications. Their anisotropic nature suggests that their optical responses such as the SERS signal, the depolarization ratio, reflectivity and ellipsometric parameters critically depend on the states of polarization, nanorod angular arrangement and specific illumination-observation geometry. SERS polarization and angular dependences of AgOADs were measured using methylene blue (MB) molecule. Our study constitutes, to our knowledge, the most detailed investigation of such characteristics of plasmonic nanostructures to date. This is due to the 90°-scattering geometry used in which two out of three Euler angles determining the nanorod spatial orientation and four polarization combinations can be varied simultaneously. We attributed the anisotropic optical response to anisotropic (pseudo)refractive index caused by different periodicity of our structures in different directions since the plasmonic properties were found rather isotropic. For the first time we demonstrate very good correspondence between SERS intensities and ellipsometric parameters for all measured configurations as compared on the basis of the surface selection rules. Obtained results enable quantitative analysis of MB Raman tensor elements, indicating that the molecules adsorb predominantly with the symmetry axis perpendicular to the surface.
On the Shortening of the Lead Time of Ocean Warm Water Volume to ENSO SST Since 2000

AbstractThe possible factors associated with the shortening of lead time between ocean warm water volume (WWV) variability along the equatorial Pacific and El Niño–Southern Oscillation (ENSO) variability after 2000 are documented. It is shown that the shortening of lead time is due to frequency increases of both WWV and ENSO. During 1979–99 the dominant frequencies were 1.5–3.5 years for both the Niño3.4 and WWV indices. In contrast, during 2000–16, both indices had a relatively flatter spectrum and were closer to a white noise process with a relative maximum at 1.5–2.0 years for the Niño3.4 index and 0.8–1.3 years for the WWV index. The frequency change of ENSO and WWV were linked to a westward shift of the Bjerknes feedback region. The results here are consistent with previous argument that the westward shift of the air-sea coupling region will cause an increase of ENSO frequency, as the corresponding zonal advection feedback reduces the period and growth of coupled instability, thus favoring more frequent and weak El Niño events.

AbstractThe Tarim River is the longest inland river at an arid area in China. Deterioration in its ecohydrological system has received much attention world widely. This study presents quantitative assessment of hydrological alterations in the hydrological regime of the Tarim River caused by reservoir irrigation and channel irrigation over a period of over a half century. The improved indicators of hydrologic alteration and range of variability approach were applied to the daily flow rates at the two representative hydrological stations. Our study shows that the annual extreme water conditions (1-, 3-, 7-day annual minimum and extreme low timing) have been altered, compared with the pre-impact period. The average flow rate in July, the 30-day annual maximum flow rates, the date for the maximum rate, the rise rate, and the fall rate show a significant decreasing trend. The improved overall degree of hydrological alteration for the two stations are approximately 68.7% and 61.8%, suggesting a high degree of alteration. This study greatly improved our understanding of impacts of irrigations on the ecohydrological characteristics in the Tarim River.

AbstractSepsis is a serious clinical problem. Negative regulation of innate immunity is associated with sepsis progression, but the underlying mechanisms remains unclear. Here we show that the receptor CD300f promotes disease progression in sepsis.CD300f−/−mice were protected from death after cecal ligation and puncture (CLP), a murine model of septic peritonitis. CD300f was highly expressed in mast cells and recruited neutrophils in the peritoneal cavity. Analysis of mice (e.g., mast cell-deficient mice) receiving transplants of wild-type orCD300f−/−mast cells or neutrophils indicated that CD300f deficiency did not influence intrinsic migratory abilities of neutrophils, but enhanced neutrophil chemoattractant production (from mast cells and neutrophils) in the peritoneal cavity of CLP-operated mice, leading to robust accumulation of neutrophils which efficiently eliminatedEscherichia coli. Ceramide-CD300f interaction suppressed the release of neutrophil chemoattractants fromEscherichia coli-stimulated mast cells and neutrophils. Administration of the reagents that disrupted the ceramide-CD300f interaction prevented CLP-induced sepsis by stimulating neutrophil recruitment, whereas that of ceramide-containing vesicles aggravated sepsis. Extracellular concentrations of ceramides increased in the peritoneal cavity after CLP, suggesting a possible role of extracellular ceramides, CD300f ligands, in the negative-feedback suppression of innate immune responses. Thus, CD300f is an attractive target for the treatment of sepsis.

Published: June 2017

AbstractBrown adipocytes play an important role in human energy metabolism and prevention of obesity and diabetes. Induced pluripotent stem cells (iPSCs) represent a promising source for brown adipocytes; however, exogenous gene induction is generally required for iPSCs generation, which might cause undesired effects particularly in long-term treatment after transplantation. We have previously reported a cocktail of six small chemical compounds that enables a conversion of human fibroblasts into chemical compound-induced neuronal cells (CiNCs). Here, we report that modified combinations of the chemical compounds and rosiglitazone, a PPARγ agonist, afforded direct conversion of human fibroblasts into brown adipocytes. The chemical compound-induced brown adipocytes (ciBAs) exhibit induction of human brown adipocyte-specific genes such as Ucp1, Ckmt1, Cited1 and other adipocyte-specific genes such as Fabp4, AdipoQ, and Pparγ. Treatment with either isoproterenol or Forskolin further induced the expression of Ucp1, suggesting that β adrenergic receptor signalling in ciBAs could be functional for induction of thermogenic genes. Moreover, oxygen consumption rates were elevated in ciBAs along with increase of cellular mitochondria. Our findings might provide an easily accessible approach for generating human brown adipocytes from fibroblasts and offer therapeutic potential for the management of obesity, diabetes, and related metabolic disorders.

Published: June 2017

Due to the increasing integration of photovoltaic‐based distributed generators (PV‐DGs), uncertainties resulted from both PV‐DG power and loads have posed a serious challenge in microgrid day‐ahead scheduling and operation. In this study, the effect of uncertainties in both PV‐DG power and loads on the microgrid day‐ahead scheduling is assessed. Specifically, the correlation between the PV‐DG power and load uncertainties is taken into account as this is closer to the reality. The probabilistic optimal power flow (P‐OPF) model is formulated to analyse the impact of the correlated PV‐DG power and load uncertainties. A modified Harr's two‐point estimation method (MH‐2PEM) is introduced to provide computation‐efficient estimation of the P‐OPF solution. Results obtained by using the MH‐2PEM and Monte Carlo simulation are compared in an equivalent 44 kV distribution feeder system and the accuracy and efficiency of the MH‐2PEM are verified. The variation ranges of the microgrid day‐ahead scheduling solution resulted from uncertainties in PV power and load are obtained with various confidence levels.
Softening effect of ultrasonic vibration on micro‐blanking deformation behaviour of titanium foil

Published: June 2017

Owing to the advantage of softening effect, ultrasonic vibration has been widely applied in forming processes for many materials such as copper and aluminium. However, related study for hard‐to‐deform materials, e.g. titanium, is less reported. In the investigation, ultrasonic vibration assisted micro‐blanking tests were carried out to improve surface quality of cross section for titanium foil (TA2) with a thickness of 0.2 mm. TA2 foil samples were annealed at different temperature to investigate the effect of ultrasonic vibration on deformation behaviour of materials with different grain sizes. The cross‐sectional profiles of square parts blanked with and without ultrasonic vibration were analysed and compared using scanning electron microscopes. Experimental results show that the ratio of smooth zone decreases with the increase of grain size. When ultrasonic vibration is applied, the ratio of smooth zone is increased by the softening effect of ultrasonic vibration. For small grain size, the softening effect of ultrasonic vibration is more remarkable. It can be attributed to that TA2 foil with small grain size has more defects and could absorb more acoustic energy. The plasticity of the material is found to be improved from the morphology at the fracture zone. This finding can provide new insights for micro‐blanking of titanium and expand the application of ultrasonic vibration.

Published: June 2017

Biomedical telemetry is an emerging field of research which enables the formation of a transmission link from inside a living body to an external device. Implantable medical devices are now one of such valuable advancement in the field of biomedical telemetry. Implantable patch antennas are gaining attention and are becoming more of a choice for implantable medical devices that uses mostly RF telemetry. In this work, a state‐of‐the‐art design for a rectangular implantable flexible patch antenna is proposed. The operation band for the antenna is chosen in the Industrial, Scientific and Medical (ISM) band (2.4–2.4835 GHz). The tiny dimension of the antenna, including the 9.45 μm thickness of the patch itself allows the antenna to be highly flexible and provides excellent results even at extreme bent conditions. For simulation environment, a three‐layer human tissue model was used, where the antenna was encapsulated between the fat and skin layer. CST Microwave Studio was chosen to design and simulate the antenna. Several performance parameters were simulated, such as the operating resonant frequency, the return loss, radiation pattern, specific absorption rate and also sensitivity of the antenna when introduced to bending.

Context. To model the cold dust emission observed in the diffuse interstellar medium, in dense molecular clouds or in cold clumps that could eventually form new stars, it is mandatory to know the physical and spectroscopic properties of this dust and to understand its emission.
Aims. This work is a continuation of previous studies aiming at providing astronomers with spectroscopic data of realistic cosmic dust analogues for the interpretation of observations. The aim of the present work is to extend the range of studied analogues to iron-rich silicate dust analogues.
Methods. Ferromagnesium amorphous silicate dust analogues were produced by a sol-gel method with a mean composition close to Mg1−xFexSiO3 with x = 0.1, 0.2, 0.3, 0.4. Part of each sample was annealed at 500 °C for two hours in a reducing atmosphere to modify the oxidation state of iron. We have measured the mass absorption coefficient (MAC) of these eight ferromagnesium amorphous silicate dust analogues in the spectral domain 30−1000 μm for grain temperature in the range 10−300 K and at room temperature in the 5−40 μm range.
Results. The MAC of ferromagnesium samples behaves in the same way as the MAC of pure Mg-rich amorphous silicate samples. In the 30−300 K range, the MAC increases with increasing grain temperature whereas in the range 10−30 K, we do not see any change of the MAC. The MAC cannot be described by a single power law in λ− β. The MAC of the samples does not show any clear trend with the iron content. However the annealing process has, on average, an effect on the MAC that we explain by the evolution of the structure of the samples induced by the processing. The MAC of all the samples is much higher than the MAC calculated by dust models.
Conclusions. The complex behavior of the MAC of amorphous silicates with wavelength and temperature is observed whatever the exact silicate composition (Mg vs. Fe amount). It is a universal characteristic of amorphous materials, and therefore of amorphous cosmic silicates, that should be taken into account in astronomical modeling. The enhanced MAC of the measured samples compared to the MAC calculated for cosmic dust model implies that dust masses are overestimated by the models.
Traumatic Suprascapular Nerve Injury at the Notch—A Reason for the Posterior Approach in Brachial Plexus Reconstruction
Authors: Seifman Marc , Ferris Scott 
Published: June 2017

Background Optimal dynamic reconstruction of shoulder function requires a functional suprascapular nerve (SSN). Nerve transfer of the distal spinal accessory nerve (dSAN) to the SSN will in many cases restore very good supraspinatus and infraspinatus function. One potential cause of failure of this nerve transfer is an unrecognized more distal injury of the SSN. An anterior approach to this transfer does not allow for visualization of the nerve at the scapular notch which is a disadvantage when compared with a posterior approach to the SSN.
Methods All patients of the senior author (S.F.) with traumatic brachial plexus injuries undergoing spinal accessory nerve to SSN transfer via the posterior approach were analyzed.
Results Of the 58 patients, 11 (19.0%) demonstrated abnormal findings at the notch. In two of these 11 patients (18.2%), reconstruction was abandoned due to severe injury of the nerve. There was a higher rate of clavicular fractures in patients with SSN injuries at the notch, compared with no SSN injury at the notch (63.6 vs. 12.8%).
Conclusion The dSAN to SSN transfer is a reliable reconstruction for restoration of shoulder external rotation and abduction. There is a high proportion of injuries to the nerve at the notch, which can be best appreciated from a posterior approach. The authors, therefore, advocate a posterior approach for this nerve transfer.
Ernährung bei Krebs: geeignet zur Vorbeugung und Therapie?
Authors: Arends Jann 
Published: June 2017

AbstractNutritional effects on cancer occurrence and on treatment outcome in cancer patients may depend on food preferences and on the quantity of foods supplied. However, it has been difficult to reliably show beneficial effects of specific dietary concepts on cancer incidence. On the other hand, obesity as a result of chronic overfeeding has been linked firmly to an increased risk of a number of cancers as well as on cancer recurrence after treatment. Metabolic consequences of obesity and other components of the metabolic syndrome may be responsible for inducing and/or promoting cancer growth and should be antagonized by regular moderate physical activity in healthy subjects and in cancer survivors. During cancer treatment and in patients with advanced disease, inadequate food intake and physical inactivity may lead to malnutrition, while recurrent and chronic systemic inflammatory reactions induce chronic catabolism with a preferential loss of muscle and cell mass, condition referred to as cachexia.

Published: June 2017

Zusammenfassung
Anamnese Ein 26-jähriger Patient stellte sich mit seit etwa 8 Wochen bestehenden Allgemeinsymptomen wie Fieber und Gewichtsverlust, aber auch frischblutigen Hämoptysen, Husten und Arthralgien vor. Bei ihm war bereits seit dem 12. Lebensjahr eine Granulomatose mit Polyangiitis (GPA, ehemals Morbus Wegener) bekannt, die im Alter von 20 Jahren eine Nierentransplantation erforderlich machte. Nur 4 Jahre nach Transplantation versagte das Transplantat irreversibel.
Untersuchungen Klinisch bestand der Verdacht auf ein Rezidiv der Erkrankung, der sich CT-morphologisch im Sinne bilateraler pulmonaler Manifestationen bestätigte. Zusätzlich fanden sich hochpositive Proteinase-3-Antikörper.
Therapie und Verlauf Nach einer Induktionstherapie mit Glukokortikoiden und Rituximab, begleitet von einem therapeutischen Plasmaaustausch, kam es zu einer deutlichen Besserung der Symptomatik, sodass der Patient in die ambulante Weiterbehandlung entlassen werden konnte.
Folgerung Eine GPA mit einem Beginn in der Kindheit ist eine lebensbedrohende Erkrankung, deren Verlauf nicht selten durch wiederholte Rezidive und eine deutlich eingeschränkte Lebensqualität für den Patienten gekennzeichnet ist.

AbstractThe German Neurological Society has conducted a survey of the structure of neurological in-patient care every other year. The present survey covers the year 2015. With a response rate of 62% in mind, the questionnaire allowed meaningful comparisons to former surveys covering the years 2013 and 2011.Only a minority of departments maintains intensive care units of their own. In contrast, 24/7 presence of neurological physicians has become standard in interdisciplinary emergency rooms. Stroke management has made neurology increasingly involved in emergency care. Since 2015, thrombectomy has been recognized as state-of-the-art therapy for a subgroup of stroke patients, raising special demands for the availability of CT and MRI on a 24/7 basis. However, infrastructure did not improve as compared to former surveys.Number of beds, total procedures and average procedures per case proceeds (case mix, case mix index) has remained roughly unchanged. However, case numbers increased, and average length of stay robustly decreased within 2 years by 17% to 5.4 days.Staff structures were heterogeneous and were involved in various duties apart from inpatient care covered by the German Diagnosis-Related Groups (DRG) system. Departments did not succeed in differentiating expenditures related to the DRG system from other procedures. Shortage of nursing staff forced 22% of departments to temporally reduce services, 6% of departments did so because of a shortage of physicians, and in 2% of departments, both occurred. Departments were confident of certifications as means of quality management, and a few suggestions were provided for more meaningful parameters for outcome-oriented quality management in the future.

Abstract
Environmental issues have always been a major issue among human kind for the past decades. As the time passes by, the technology field has grown and has helped a lot in order to reduce these environmental issues. Industries such as metal plating facilities, mining operations and batteries production are a few examples that involves in the environmental issues. Carbon nanotube is proven to possess excellent adsorption capacity for the removal of methylene blue and orange red dyes. The effect of process parameters such as pH and contact time was investigated The results revealed that optimized conditions for the highest removal for methylene blue (MB) (97%) and orange red (94%) are at pH 10, CNTs dosage of 1 grams, and 15 minutes for each dyes removal respectively. The equilibrium adsorption data obtained was best fit to Freundlich model, while kinetic data can be characterized by the pseudo second-order rate kinetics.
Algebraic matroids are almost entropic
Authors: Matúš František 
Published: June 2017

Algebraic matroids capture properties of the algebraic dependence among elements of extension fields. Almost entropic matroids have the rank functions arbitrarily well approximated by the entropies of subvectors of random vectors. The former class of matroids is included in the latter. A key argument in the proof is the Lang-Weil bound on the number of points in algebraic varieties.
