Interdependence of ATP signalling and pannexin channels; the servant was really the master all along?
Authors: Jackson Michael F.
Published: November 2015

Pannexin channels are recognized as important conduits for the release of ATP, which contributes to purinergic signalling. Pathologically, ATP release via these channels acts as a find-me signal for apoptotic cell clearance. Accordingly, there is considerable and growing interest in understanding the function and regulation of pannexin channels. In a recent issue of the Biochemical Journal, Boyce et al. provide evidence that the surface expression of pannexin channels is regulated by extracellular ATP. They propose a model in which ATP triggers pannexin channel internalization through a pathway involving clathrin- and caveolin-independent entry into early endosomes. Intriguingly, their evidence suggests that internalization is initiated through the association of ATP with pannexin channels themselves as well as ionotropic purinergic receptor 7 (P2X7) receptors.
A reductionist approach to model photosynthetic self-regulation in eukaryotes in response to light
Authors: Matuszyńska Anna , Ebenhöh Oliver
Published: November 2015

Along with the development of several large-scale methods such as mass spectrometry or micro arrays, genome wide models became not only a possibility but an obvious tool for theoretical biologists to integrate and analyse complex biological data. Nevertheless, incorporating the dynamics of photosynthesis remains one of the major challenges while reconstructing metabolic networks of plants and other photosynthetic organisms. In this review, we aim to provide arguments that small-scale models are still a suitable choice when it comes to discovering organisational principles governing the design of biological systems. We give a brief overview of recent modelling efforts in understanding the interplay between rapid, photoprotective mechanisms and the redox balance within the thylakoid membrane, discussing the applicability of a reductionist approach in modelling self-regulation in plants and outline possible directions for further research.
A multi-scale, multi-disciplinary approach for assessing the technological, economic and environmental performance of bio-based chemicals
Authors: Herrgård Markus , Sukumara Sumesh , Campodonico Miguel , Zhuang Kai
Published: November 2015

In recent years, bio-based chemicals have gained interest as a renewable alternative to petrochemicals. However, there is a significant need to assess the technological, biological, economic and environmental feasibility of bio-based chemicals, particularly during the early research phase. Recently, the Multi-scale framework for Sustainable Industrial Chemicals (MuSIC) was introduced to address this issue by integrating modelling approaches at different scales ranging from cellular to ecological scales. This framework can be further extended by incorporating modelling of the petrochemical value chain and the de novo prediction of metabolic pathways connecting existing host metabolism to desirable chemical products. This multi-scale, multi-disciplinary framework for quantitative assessment of bio-based chemicals will play a vital role in supporting engineering, strategy and policy decisions as we progress towards a sustainable chemical industry.
Quantitative analysis of drug effects at the whole-body level: a case study for glucose metabolism in malaria patients
Authors: Snoep Jacky L. , Green Kathleen , Eicher Johann , Palm Daniel C. , Penkler Gerald , du Toit Francois , Walters Nicolas , Burger Robert , Westerhoff Hans V. , van Niekerk David D.
Published: November 2015

We propose a hierarchical modelling approach to construct models for disease states at the whole-body level. Such models can simulate effects of drug-induced inhibition of reaction steps on the whole-body physiology. We illustrate the approach for glucose metabolism in malaria patients, by merging two detailed kinetic models for glucose metabolism in the parasite Plasmodium falciparum and the human red blood cell with a coarse-grained model for whole-body glucose metabolism. In addition we use a genome-scale metabolic model for the parasite to predict amino acid production profiles by the malaria parasite that can be used as a complex biomarker.
Genome-scale modelling of microbial metabolism with temporal and spatial resolution
Authors: Henson Michael A.
Published: November 2015

Most natural microbial systems have evolved to function in environments with temporal and spatial variations. A major limitation to understanding such complex systems is the lack of mathematical modelling frameworks that connect the genomes of individual species and temporal and spatial variations in the environment to system behaviour. The goal of this review is to introduce the emerging field of spatiotemporal metabolic modelling based on genome-scale reconstructions of microbial metabolism. The extension of flux balance analysis (FBA) to account for both temporal and spatial variations in the environment is termed spatiotemporal FBA (SFBA). Following a brief overview of FBA and its established dynamic extension, the SFBA problem is introduced and recent progress is described. Three case studies are reviewed to illustrate the current state-of-the-art and possible future research directions are outlined. The author posits that SFBA is the next frontier for microbial metabolic modelling and a rapid increase in methods development and system applications is anticipated.
Modelling metabolic evolution on phenotypic fitness landscapes: a case study on C4 photosynthesis
Authors: Heckmann David
Published: November 2015

How did the complex metabolic systems we observe today evolve through adaptive evolution? The fitness landscape is the theoretical framework to answer this question. Since experimental data on natural fitness landscapes is scarce, computational models are a valuable tool to predict landscape topologies and evolutionary trajectories. Careful assumptions about the genetic and phenotypic features of the system under study can simplify the design of such models significantly. The analysis of C4 photosynthesis evolution provides an example for accurate predictions based on the phenotypic fitness landscape of a complex metabolic trait. The C4 pathway evolved multiple times from the ancestral C3 pathway and models predict a smooth ‘Mount Fuji’ landscape accordingly. The modelled phenotypic landscape implies evolutionary trajectories that agree with data on modern intermediate species, indicating that evolution can be predicted based on the phenotypic fitness landscape. Future directions will have to include structural changes of metabolic fitness landscape structure with changing environments. This will not only answer important evolutionary questions about reversibility of metabolic traits, but also suggest strategies to increase crop yields by engineering the C4 pathway into C3 plants.
T-cells require post-transcriptional regulation for accurate immune responses
Authors: Salerno Fiamma , Wolkers Monika C.
Published: November 2015

Cytotoxic T-cells are crucial to protect us from intracellular pathogens and malignant cells. When T-cells become activated, they rapidly secrete cytokines, chemokines and cytotoxic granules that are critical to clear infected cells. However, when not properly regulated, these toxic effector molecules become one of the key mediators of autoimmune diseases. Therefore, a tight and multi-layered regulation of gene expression and protein production is required to ensure a protective yet balanced immune response. In this review, we describe how post-transcriptional events modulate the production of effector molecules in T-cells. In particular, we will focus on the role of cis-regulatory elements within the 3′-UTR of specific mRNAs and on RNA-binding proteins (RBPs) and non-coding RNAs that control the initiation and resolution of T-cell responses.
Resource allocation in metabolic networks: kinetic optimization and approximations by FBA
Authors: Müller Stefan , Regensburger Georg , Steuer Ralf
Published: November 2015

Based on recent theoretical results on optimal flux distributions in kinetic metabolic networks, we explore the congruences and differences between solutions of kinetic optimization problems and results obtained by constraint-based methods. We demonstrate that, for a certain resource allocation problem, kinetic optimization and standard flux balance analysis (FBA) give rise to qualitatively different results. Furthermore, we introduce a variant of FBA, called satFBA, whose predictions are in qualitative agreement with kinetic optimization.
Ribosomal profiling adds new coding sequences to the proteome
Authors: Mumtaz Muhammad Ali S. , Couso Juan Pablo
Published: November 2015

Next generation sequencing (NGS) has enabled an in-depth look into genes, transcripts and their translation at the genomic scale. The application of NGS sequencing of ribosome footprints (Ribo-Seq) reveals translation with single nucleotide (nt) resolution, through the deep sequencing of ribosome-bound fragments (RBFs). Some results of Ribo-Seq challenge our understanding of the protein-coding potential of the genome. Earlier bioinformatic approaches had shown the presence of hundreds of thousands of putative small ORFs (smORFs) in eukaryotic genomes, but they had been largely ignored due to their large numbers and difficulty in determining their translation and function. Ribo-Seq has revealed that hundreds of putative smORFs within previously assumed long non-coding RNAs (lncRNAs) and UTRs of canonical mRNAs are associated with ribosomes, appearing to be translated. Here we review some of the approaches used to define translation within Ribo-Seq experiments and the challenges in defining translation of these novel smORFs in lncRNAs and UTRs. We also look at some of the bioinformatic and biochemical approaches used to independently corroborate these exciting new findings and elucidate real translation events.
Simple adaptive output‐feedback control of non‐linear strict‐feedback time‐delay systems
Authors: Ho Choi Yun , Jin Yoo Sung
Published: November 2015

An adaptive output‐feedback control approach is proposed for uncertain non‐linear systems with unknown time delays in strict‐feedback form. A linear observer is designed to estimate unmeasurable state variables. In contrast to the existing controllers for strict‐feedback systems, the adaptive control design using only single fuzzy approximation (SFA) is presented. In the controller design procedure, unknown non‐linear functions including unknown non‐linearities caused by compensating time‐delay functions are derived to design virtual controllers. They are not approximated by using fuzzy logic systems at each step of the backstepping design, but just passed down to the next step. Finally, a lumped unknown non‐linear function including non‐linearities of observer error dynamics is defined at the last step and estimated by SFA in order to design the actual control law. Thus, the actual control law using SFA can be implemented, without calculating virtual control laws. Compared with existing output‐feedback control approaches for strict‐feedback time‐delay systems, the proposed control system has a relatively simple structure in that it overcomes the problem of using multiple approximators as well as the problem of calculating the repeated differentiations of virtual controllers. In addition, we show that all signals in the closed‐loop system are uniformly ultimately bounded and the tracking error converges to an adjustable neighbourhood of the origin.
Achieving uniform perpendicular magnetic field distribution for near‐field ultra‐high frequency radio‐frequency identification
Authors: Shen Laiwei , Zhuang Wei , Tang Wanchun , Ma Jian
Published: November 2015

In this study, a new antenna is proposed to achieve uniform perpendicular magnetic field distribution for near‐field ultra‐high frequency radio‐frequency identification. The antenna is based on ‘interdigital‐oppositely directed currents (ODCs)’ that is formed by introducing another current between the two oppositely directed currents of ODCs. By adjusting the feeding phase of the newly introduced current, the uniformity of perpendicular magnetic field distribution can be improved. The design procedure of the antenna is presented and the uniform perpendicular magnetic field distribution of the antenna is achieved and verified by experiments. When the transmitting power of the proposed antenna is 1 W, the interrogation area for 100% tag detection is 49 × 16 cm2 with an observing height of 5 cm for Impinj J41 near‐field tags.

Published: November 2015

The present paper summarizes the results obtained from the past few years in the framework of the Enhanced Multi-Ionization of short-Lived Isotopes for Eurisol (EMILIE) project. The EMILIE project aims at improving the charge breeding techniques with both Electron Cyclotron Resonance Ion Sources (ECRIS) and Electron Beam Ion Sources (EBISs) for European Radioactive Ion Beam (RIB) facilities. Within EMILIE, an original technique for debunching the beam from EBIS charge breeders is being developed, for making an optimal use of the capabilities of CW post-accelerators of the future facilities. Such a debunching technique should eventually resolve duty cycle and time structure issues which presently complicate the data-acquisition of experiments. The results of the first tests of this technique are reported here. In comparison with charge breeding with an EBIS, the ECRIS technique had lower performance in efficiency and attainable charge state for metallic ion beams and also suffered from issues related to beam contamination. In recent years, improvements have been made which significantly reduce the differences between the two techniques, making ECRIS charge breeding more attractive especially for CW machines producing intense beams. Upgraded versions of the Phoenix charge breeder, originally developed by LPSC, will be used at SPES and GANIL/SPIRAL. These two charge breeders have benefited from studies undertaken within EMILIE, which are also briefly summarized here.

CERN’s 160 MeV H− linear accelerator (Linac4) is a key constituent of the injector chain upgrade of the Large Hadron Collider that is being installed and commissioned. A cesiated surface ion source prototype is being tested and has delivered a beam intensity of 45 mA within an emittance of 0.3 π ⋅ mm ⋅ mrad. The optimum ratio of the co-extracted electron- to ion-current is below 1 and the best production efficiency, defined as the ratio of the beam current to the 2 MHz RF-power transmitted to the plasma, reached 1.1 mA/kW. The H− source prototype and the first tests of the new ion source optics, electron-dump, and front end developed to minimize the beam emittance are presented. A temperature regulated magnetron H− source developed by the Brookhaven National Laboratory was built at CERN. The first tests of the magnetron operated at 0.8 Hz repetition rate are described.
Effect of oxygen content of Nd–Fe–B sintered magnet on grain boundary diffusion process of DyH2 dip-coating
Authors: Bae Kyoung-Hoon , Lee Seong-Rae , Kim Hyo-Jun , Lee Min-Woo , Jang Tae-Suk
Published: November 2015

We investigated the effect of oxygen content on the microstructural and magnetic properties of a DyH2 dip-coated Nd–Fe–B sintered magnet. When the magnet had a low oxygen content (1500 ppm), the volume and size of the rare-earth-rich oxide (Nd–Dy–O) phase was reduced, and a uniform and continuous thin Nd-rich grain boundary phase (GBP) was well developed. The grain boundary diffusion depth of Dy increased from 200 to 350 μm with decreasing oxygen content from ∼3000 to 1500 ppm. The coercivity of the low-oxygen magnet increased from 19.98 to 23.59 kOe after grain boundary diffusion process (GBDP) while the remanence reduction was minimized. The formation of an fcc-NdOx Nd-rich phase in the high-oxygen magnet hindered the formation of a Nd-rich triple-junction phase and GBP. In contrast, a metallic dhcp-Nd phase, which was closely related to coercivity enhancement after GBDP, was formed in the low-oxygen magnet.
Terahertz signal detection in a short gate length field-effect transistor with a two-dimensional electron gas
Authors: Vostokov N. V. , Shashkin V. I.
Published: November 2015

We consider the problem of non-resonant detection of terahertz signals in a short gate length field-effect transistor having a two-dimensional electron channel with zero external bias between the source and the drain. The channel resistance, gate-channel capacitance, and quadratic nonlinearity parameter of the transistor during detection as a function of the gate bias voltage are studied. Characteristics of detection of the transistor connected in an antenna with real impedance are analyzed. The consideration is based on both a simple one-dimensional model of the transistor and allowance for the two-dimensional distribution of the electric field in the transistor structure. The results given by the different models are discussed.
Direct growth of graphene on in situ epitaxial hexagonal boron nitride flakes by plasma-assisted molecular beam epitaxy
Authors: Xu Zhongguang , Zheng Renjing , Khanaki Alireza , Zuo Zheng , Liu Jianlin
Published: November 2015

Hexagonal boron nitride (h-BN) single-crystal domains were grown on cobalt (Co) substrates at a substrate temperature of 850–900 °C using plasma-assisted molecular beam epitaxy. Three-point star shape h-BN domains were observed by scanning electron microscopy, and confirmed by Raman and X-ray photoelectron spectroscopy. The h-BN on Co template was used for in situ growth of multilayer graphene, leading to an h-BN/graphene heterostructure. Carbon atoms preferentially nucleate on Co substrate and edges of h-BN and then grow laterally to form continuous graphene. Further introduction of carbon atoms results in layer-by-layer growth of graphene on graphene and lateral growth of graphene on h-BN until it may cover entire h-BN flakes.
Calculating false cognates
Authors: Kilani Marwan
Published: November 2015

This paper presents an extension of Baxter & Manaster-Ramer’s (2000) approach to the problem of false cognates in the determination of relationships between languages. Their approach uses a Monte Carlo simulation to estimate how many lexical similarities we can expect to be due to chance between two lexical lists from different languages, and consequently how many are too many to be all false cognates. Although very efficient, their model has the shortcoming of being applicable only to simple lexical lists such as the Swadesh list, with one-to-one semantic correspondences between the individual terms. Here I present a new model that can be applied to any kind of word list, and can include comparisons between multiple terms sharing the same semantic field. After a theoretical description, a controlled test and a contra-test, I finally apply the method to a real test case, investigating the probability of relation between Pre-Greek, the nonIndo-European substrate of classical Greek, and Proto-Basque, Proto-Uralic and ‘Proto-Altaic’.
Climate-induced mortality of spruce stands in Belarus
Authors: Kharuk Viacheslav I , Im Sergei T , Dvinskaya Maria L , Golukov Alexei S , Ranson Kenneth J
Published: November 2015

The aim of this work is an analysis of the causes of spruce (Picea abies L.) decline and mortality in Belarus. The analysis was based on forest inventory and Landsat satellite (land cover classification, climate variables (air temperature, precipitation, evaporation, vapor pressure deficit, SPEI drought index)), and GRACE-derived soil moisture estimation (equivalent of water thickness anomalies, EWTA). We found a difference in spatial patterns between dead stands and all stands (i.e., before mortality). Dead stands were located preferentially on relief features with higher water stress risk (i.e., higher elevations, steeper slopes, south and southwestern exposure). Spruce mortality followed a series of repeated droughts between 1990 and 2010. Mortality was negatively correlated with air humidity (r = –0.52), and precipitation (r = –0.57), and positively correlated with the prior year vapor pressure deficit (r = 0.47), and drought increase (r = 0.57). Mortality increased with the increase in occurrence of spring frosts (r = 0.5), and decreased with an increase in winter cloud cover (r = –0.37). Spruce mortality was negatively correlated with snow water accumulation (r = –0.81) and previous year anomalies in water soil content (r = –0.8). Weakened by water stress, spruce stands were attacked by pests and phytopathogens. Overall, spruce mortality in Belarussian forests was caused by drought episodes and drought increase in synergy with pest and phytopathogen attacks. Vast Picea abies mortality in Belarus and adjacent areas of Russia and Eastern Europe is a result of low adaptation of that species to increased drought. This indicates the necessity of spruce replacement by drought-tolerant indigenous (e.g., Pinus sylvestris, Querqus robur) or introduced (e.g., Larix sp. or Pseudotsuga menzieslii) species to obtain sustainable forest growth management.

We present observations at 610 and 235 MHz using the Giant Metrewave Radio Telescope (GMRT) of the recurrent nova V745 Scorpii which recorded its last outburst on 2014 February 6. This is the second symbiotic recurrent nova whose light curve at low frequencies has been followed in detail, the first being RS Ophiuchi in 2006. We fitted the 610 MHz light curve by a model of synchrotron emission from an expanding shell being modified by radiative transfer effects due to local absorbing gas consisting of a uniformly distributed and a clumpy component. Using our model parameters, we find that the emission at 235 MHz peaked around day 35 which is consistent with our GMRT observations. The two main results of our study are (1) The radio emission at a given frequency is visible sooner after the outburst in successive outbursts of both V745 Scorpii and RS Ophiuchi. The earlier detection of radio emission is interpreted to be caused by decreasing foreground densities. (2) The clumpy material, if exists, is close to the white dwarf and can be interpreted as being due to the material from the hot accretion disc. The uniform density gas is widespread and attributed to the winds blown by the white dwarf. We present implications of these results on the evolution of both novae. Such studies along with theoretical understanding have the potential of resolving several outstanding issues such as why all recurrent novae are not detectable in synchrotron radio and whether recurrent novae are progenitor systems of Type 1a supernova.
A timing constraint on the (total) mass of the Large Magellanic Cloud

Published: November 2015

This paper explores the effect of the Large Magellanic Cloud (LMC) on the mass estimates obtained from the timing argument. We show that accounting for the presence of the LMC systematically lowers the Local Group mass (MLG) derived from the relative motion of the Milky Way–Andromeda pair. Motivated by this result, we apply a Bayesian technique devised by Peñarrubia et al. to simultaneously fit (i) distances and velocities of galaxies within 3 Mpc and (ii) the relative motion between the Milky Way and Andromeda derived from HST observations, with the LMC mass (MLMC) as a free parameter. Our analysis returns a Local Group mass $M_{\rm LG}=2.64^{+0.42}_{-0.38}\times 10^{12}\,\mathrm{M}_{\odot }$ at a 68 per cent confidence level. The masses of the Milky Way, $M_{\rm MW}=1.04_{-0.23}^{+0.26}\times 10^{12}\,\mathrm{M}_{\odot }$, and Andromeda, $M_{{\rm M}31}=1.33_{-0.33}^{+0.39}\times 10^{12}\,\mathrm{M}_{\odot }$, are consistent with previous estimates that neglect the impact of the LMC on the observed Hubble flow. We find a (total) LMC mass $M_{\rm LMC}=0.25_{-0.08}^{+0.09}\times 10^{12}\,\mathrm{M}_{\odot }$, which is indicative of an extended dark matter halo and supports the scenario where this galaxy is just past its first pericentric approach. Consequently, these results suggest that the LMC may induce significant perturbations on the Galactic potential.
