MOF‐Based Mixed‐Matrix Membranes in Gas Separation – Mystery and Reality
Authors: Friebe Sebastian , Diestel Lisa , Knebel Alexander , Wollbrink Alexander , Caro Jürgen 
Published: July 2016

AbstractMicroporous additives like nanosized metal‐organic framework (MOF) particles can improve the gas separation performance of polymer membranes. These membranes which consist of added filler particles in a continuous polymer phase are called mixed‐matrix membranes (MMM). While inorganic zeolites and organic polymers do not match well, the preparation of defect‐free MOF‐based MMMs is much easier. However, some problems can also occur during the preparation. Solutions how to avoid them and prepare perfect MMMs are given. In practical gas separation, the selectivity of the MMMs was found to be even higher than predicted by the Maxwell model.
A comparison of absolute performance of different correlative and mechanistic species distribution models in an independent area
Authors: Shabani Farzin , Kumar Lalit , Ahmadi Mohsen 
Published: July 2016

AbstractTo investigate the comparative abilities of six different bioclimatic models in an independent area, utilizing the distribution of eight different species available at a global scale and in Australia. Global scale and Australia. We tested a variety of bioclimatic models for eight different plant species employing five discriminatory correlative species distribution models (SDMs) including Generalized Linear Model (GLM), MaxEnt, Random Forest (RF), Boosted Regression Tree (BRT), Bioclim, together with CLIMEX (CL) as a mechanistic niche model. These models were fitted using a training dataset of available global data, but with the exclusion of Australian locations. The capabilities of these techniques in projecting suitable climate, based on independent records for these species in Australia, were compared. Thus, Australia is not used to calibrate the models and therefore it is as an independent area regarding geographic locations. To assess and compare performance, we utilized the area under the receiver operating characteristic (ROC) curves (AUC), true skill statistic (TSS), and fractional predicted areas for all SDMs. In addition, we assessed satisfactory agreements between the outputs of the six different bioclimatic models, for all eight species in Australia. The modeling method impacted on potential distribution predictions under current climate. However, the utilization of sensitivity and the fractional predicted areas showed that GLM, MaxEnt, Bioclim, and CL had the highest sensitivity for Australian climate conditions. Bioclim calculated the highest fractional predicted area of an independent area, while RF and BRT were poor. For many applications, it is difficult to decide which bioclimatic model to use. This research shows that variable results are obtained using different SDMs in an independent area. This research also shows that the SDMs produce different results for different species; for example, Bioclim may not be good for one species but works better for other species. Also, when projecting a “large” number of species into novel environments or in an independent area, the selection of the “best” model/technique is often less reliable than an ensemble modeling approach. In addition, it is vital to understand the accuracy of SDMs' predictions. Further, while TSS, together with fractional predicted areas, are appropriate tools for the measurement of accuracy between model results, particularly when undertaking projections on an independent area, AUC has been proved not to be. Our study highlights that each one of these models (CL, Bioclim, GLM, MaxEnt, BRT, and RF) provides slightly different results on projections and that it may be safer to use an ensemble of models.
Advances in Upgrading Lignin Pyrolysis Vapors by Ex Situ Catalytic Fast Pyrolysis
Authors: Xu Lujiang , Zhang Ying , Fu Yao 
Published: July 2016

AbstractLignin, a highly branched, substituted, mononuclear aromatic polymer, is one of the principal components of lignocellulosic biomass. Its valorization is considered an important part of the modern biorefinery scheme. However, as a result of the natural complexity and high stability of lignin, its depolymerization and the following conversion are challenging. The unique structure and composition of lignin offer many possible routes to produce liquid fuels and chemicals. Recognized as an efficient and feasible process, ex situ catalytic fast pyrolysis (CFP) has attracted much attention for upgrading lignin and lignin pyrolysis vapors. The main challenge of this process is the development of active and stable catalysts that can effectively break the C−O bond of lignin and decompose the intermediates. In this Review, we aim to provide an overview of recent advances on a related topic. The Review introduces ex situ CFP, the reactions and pathways of lignin vapors in the ex situ CFP process, and summarizes in detail recent progress in experimental studies on upgrading lignin‐derived model phenols, lignin, and lignin pyrolysis vapors to hydrocarbons by the ex situ CFP process over different catalysts.
The effects of carbamazepine in the intrahippocampal kainate model of temporal lobe epilepsy depend on seizure definition and mouse strain
Authors: Twele Friederike , Töllner Kathrin , Bankstahl Marion , Löscher Wolfgang 
Published: July 2016

SummaryObjectiveMesial temporal lobe epilepsy (TLE) with hippocampal sclerosis is a predominant form of acquired epilepsy, characterized by recurrent simple and complex partial seizures that are often resistant to treatment. Mice developing spontaneous recurrent nonconvulsive and convulsive seizures after intrahippocampal injection of the excitotoxic glutamate agonist kainate are thought to represent a valuable model of mesial TLE. Epileptic electroencephalogram (EEG) activity recorded in this model from the kainate focus in the ipsilateral hippocampus is resistant to antiseizure drugs such as carbamazepine (CBZ). We compared the efficacy of CBZ in this model in two different mouse strains (FVB/N and NMRI). Furthermore, we evaluated whether changes in the definition of electrographic seizures affect the antiseizure efficacy of CBZ.MethodsAs in previous studies, two types of epileptic EEG activity were defined: high‐voltage sharp waves (HVSWs) and hippocampal paroxysmal discharges (HPDs). The characteristics of these paroxysmal EEG events in epileptic mice were compared with EEG criteria for nonconvulsive seizures in patients. For HVSWs, different spike frequencies, interevent intervals, and amplitudes were used as inclusion and exclusion criteria. In addition to CBZ, some experiments were performed with diazepam (DZP) and phenobarbital (PB).ResultsFemale epileptic FVB/N mice predominantly exhibited frequent HVSWs, but only infrequent HPDs or secondarily generalized convulsive seizures. Slight changes in HVSW definition determined whether they were resistant or responsive to CBZ. Male NMRI mice exhibited both HVSWs and HPDs. HVSWs were more resistant than HPDs to suppression by CBZ. Both types of epileptic EEG activity were rapidly suppressed by DZP and PB.SignificanceThe data demonstrate that focal electrographic seizures in the intrahippocampal kainate mouse model are less resistant than previously thought. Both mouse strain and the criteria chosen for definition of EEG seizures determine whether such seizures are drug‐resistant or ‐responsive.

Superfluidity targets 5G networks, by addressing key network operator challenges with a multi‐pronged approach, based on the concept of a flexible, highly adaptive, superfluid network. Superfluidity supports rapid service deployment and migration in a heterogeneous network environment, regardless of the underlying hardware. The overall proposal offers advanced capabilities in terms of service deployment and interoperability, while guaranteeing high‐performance levels end‐to‐end. Copyright © 2016 John Wiley & Sons, Ltd.
The rich somatic life of Wolbachia
Authors: Pietri Jose E. , DeBruhl Heather , Sullivan William 
Published: July 2016

AbstractWolbachia is an intracellular endosymbiont infecting most arthropod and some filarial nematode species that is vertically transmitted through the maternal lineage. Due to this primary mechanism of transmission, most studies have focused on Wolbachia interactions with the host germline. However, over the last decade many studies have emerged highlighting the prominence of Wolbachia in somatic tissues, implicating somatic tissue tropism as an important aspect of the life history of this endosymbiont. Here, we review our current understanding of Wolbachia–host interactions at both the cellular and organismal level, with a focus on Wolbachia in somatic tissues.

ScopeHeat‐stabilized rice bran (SRB) and cooked navy bean powder (NBP) contain a variety of phytochemicals that are fermented by colonic microbiota and may influence intestinal health. Dietary interventions with these foods should be explored for modulating colorectal cancer risk.Methods and resultsA randomized‐controlled pilot clinical trial investigated the effects of eating SRB (30 g/day) or cooked navy bean powder (35 g/day) on gut microbiota and metabolites (NCT01929122). Twenty‐nine overweight/obese volunteers with a prior history of colorectal cancer consumed a study‐provided meal and snack daily for 28 days. Volunteers receiving SRB or NBP showed increased gut bacterial diversity and altered gut microbial composition at 28 days compared to baseline. Supplementation with SRB or NBP increased total dietary fiber intake similarly, yet only rice bran intake led to a decreased Firmicutes:Bacteroidetes ratio and increased SCFA (propionate and acetate) in stool after 14 days but not at 28 days.ConclusionThese findings support modulation of gut microbiota and fermentation byproducts by SRB and suggest that foods with similar ability to increase dietary fiber intake may not have equal effects on gut microbiota and microbial metabolism.
A 220 GHz subharmonic mixer based on schottky diodes with an accurate terahertz diode model
Authors: Zhang Yong , Zhao Wei , Wang Yunfei , Ren Tianhao , Chen Yapei 
Published: July 2016

ABSTRACTThis article introduces the design process of a 220 GHz subharmonic mixer with low conversion loss, which is comprised of a pair of anti‐parallel Schottky diodes (SBD). For terahertz circuits, the wavelength of the electromagnetic (EM) wave is very close to the size of devices, which results in complicated parasitic effects. This will leads to a very limited optimization space for circuits design when matching the impedance. To solve this problem, we developed the precise 3D EM planar SBD model and the field‐circuit co‐simulation method to design this terahertz mixer. The diodes are mounted on the quartz‐based suspended microstrip line. The measured results show that the single side band conversion loss is less than 12 dB during radio frequency (RF) range from 211 to 226 GHz and the minimum loss is about 5.9 dB. With the intermediate frequency fixed at 1 GHz, the conversion loss varies from 8 dB to 11.2 dB over the RF bandwidth of 211 to 221 GHz. The mixer can be applied in heterodyne receivers of terahertz systems. © 2016 Wiley Periodicals, Inc. Microwave Opt Technol Lett 58:2311–2316, 2016

Authors: Yin Jiaqing , Li Zhipeng , Zhang Ting , Bao Jingfu , Lv Juncai 
Published: July 2016

ABSTRACTThis article introduces a novel high Q‐factor substrate integrated waveguide (SIW) cavity resonator and its application of Ku‐band low phase noise oscillator. Q‐factor of the proposed resonator is improved by using the L‐slot and the higher order mode. The L‐slot is placed on edge of TE102 mode field. Therefore, the L‐slot has little influence on resonant frequency but can obviously enhance roll‐off characteristic of S11. And the high order modes have the bigger Q value than fundamental mode. The negative resistance oscillator based on the proposed SIW cavity resonator is easily designed and tested. The experimental results of Ku‐band oscillator show outstanding low phase noise of −130.43 dBc/Hz at 1 MHz offset frequency from 15.55 GHz carrier frequency. © 2016 Wiley Periodicals, Inc.

A compact wide bandwidth bandpass filter with SIR and S‐shaped coupled spiral resonator
Authors: Son Kwang Chul , Shrestha Bhanu , Yoon Ki‐Cheol 
Published: July 2016

ABSTRACTThis article proposes a compact wide bandwidth band pass filter (BPF) with a stepped impedance resonator (SIR) and an S‐shaped coupled spiral resonator. The SIR has a wide bandwidth while the S‐shaped coupled line has a compact structure due to the spiral type resonator. The BPF used the S‐shaped folded structure instead of the λg/4 transmission line to reduce the size and to enhance the performance of the BPF. The via‐hole was not used in order to keep the design simple. Due to the narrow coupling gap, the bandwidth of conventional BPFs can barely exceed 40%. However, in this work, the proposed BPF achieved a bandwidth of 68%, which is larger than the conventional filter. The experimental results in terms of insertion loss (S21) and return loss (S11) are 0.61 dB and 15.7 dB at 5.3 GHz. The smaller size of the BPF is suitable for microwave communication systems. © 2016 Wiley Periodicals, Inc. Microwave Opt Technol Lett 58:2334–2336, 2016

Published: July 2016

ABSTRACTAn Ultra‐thin Miniaturized Metamaterial Perfect Absorber operating over the X‐band frequencies with improved selectivity performance is proposed. The structure uses rectangular patches partly encircled by L‐shaped metallic strips, placed diagonally on the top plane of the component and a concentric split‐ring in the center. The component exhibits broadband absorption response over the entire X‐band range with two absorption peaks at 7.8 GHz and 9.86 GHz, respectively. The structure has been simulated for different angles of oblique incidence and it gave good results under such circumstances. Also, the thickness of the substrate is very less (about 0.07λ, with respect to the center frequency of the bandwidth) and a comparative study of the proposed structure with other similar structures available in literature is furnished to establish the improved performance of the same. © 2016 Wiley Periodicals, Inc.

Authors: Bedar Khan Zafar , Huiling Zhao , Yimin Zhang 
Published: July 2016

ABSTRACTThe simplified design approach presented in this letter for realization of a dual‐band Wilkinson power divider (WPD) comprising of three transmission line sections reduces the mathematical complexity to half as compared to earlier presented work. Based on the mathematical derivation through even mode circuit analysis only, design guidelines are presented. Comparison is drawn between the new and the previous design guidelines. In order to show the efficacy of the proposed simplified design approach, a dual‐band WPD operating at 1 and 3 GHz is designed, simulated, and manufactured. The simulated and measured results show excellent conformance in the S‐parameter response. Measured figure of merits (FOMs) show good performance of the WPD. For instance, insertion loss comes out to be less than 3.3 dB, whereas return loss and isolation between the ports is better than −30 and −27 dB, respectively, at the two frequencies. © 2016 Wiley Periodicals, Inc.

Published: July 2016

ABSTRACTThis letter presents the design and measured results of a wideband dual‐polarized array antenna for K/Ka‐band wireless communication. The proposed antenna is assembled with several single‐layer low‐permittivity dielectric substrates and two hollow aluminum plates. A rectangular patch, with a parasitic square patch above and a 0.5 mm‐air‐layer in between, is designed as the basic radiating element. Constrained feeding and coupling feeding are both imposed on the rectangular patches with a common ground to separate two feeding networks and optimization of the feeding networks is implemented to solve the coupling problem. As an example, an 8 × 8 array is designed and fabricated. Measured results show that a bandwidth of 21.4% from 25 GHz to 31 GHz has been achieved, with a gain more than 20 dBi and an isolation more than 30 dB for the orthogonal polarizations throughout the whole band. The cross‐polarization level is less than −20 dB. © 2016 Wiley Periodicals, Inc. Microwave Opt Technol Lett 58:2377–2381, 2016
