ZFAS1 functions as an oncogenic long non-coding RNA in bladder cancer
Authors: Yang Haifan , Li Ge , Cheng Bo , Jiang Rui
Published: April 2018

Long non-coding RNA (lncRNA) ZFAS1 (zinc finger antisense 1) has been suggested to have an oncogenic role in the tumorigenesis of human malignant tumors. However, the expression status and biological function of ZFAS1 in bladder cancer is still unknown. Thus, the purpose of the present study is to explore the clinical value of ZFAS1 in bladder cancer patients, and the biological function of ZFAS1 in bladder cancer cell. In the present study, we found ZFAS1 expression was increased in bladder cancer tissues compared with paired adjacent normal tissues through analyzing the Cancer Genome Atlas (TCGA) database. Furthermore, we confirmed that levels of ZFAS1 expression were elevated in bladder cancer tissues and cell lines compared with normal bladder tissues and normal uroepithelium cell line, respectively. Then, we observed that the expression level of ZFAS1 was positively associated with clinical stag, muscularis invasion, lymph node metastasis, and distant metastasis in bladder cancer patients. The experiments in vitro suggested that knockdown of ZFAS1 repressed bladder cancer cell proliferation via up-regulating KLF2 and NKD2 expression, and inhibited cell migration and invasion via down-regulating ZEB1 and ZEB2 expression. In conclusion, ZFAS1 is overexpressed in bladder cancer, and functions as an oncogenic lncRNA in regulating bladder cancer cell proliferation, migration, and invasion.
Studying X chromosome inactivation in the single-cell genomic era
Authors: Keniry Andrew , Blewitt Marnie E.
Published: April 2018

Single-cell genomics is set to revolutionise our understanding of how epigenetic silencing works; by studying specific epigenetic marks or chromatin conformations in single cells, it is possible to ask whether they cause transcriptional silencing or are instead a consequence of the silent state. Here, we review what single-cell genomics has revealed about X chromosome inactivation, perhaps the best characterised mammalian epigenetic process, highlighting the novel findings and important differences between mouse and human X inactivation uncovered through these studies. We consider what fundamental questions these techniques are set to answer in coming years and propose that X chromosome inactivation is an ideal model to study gene silencing by single-cell genomics as technical limitations are minimised through the co-analysis of hundreds of genes.
On the coupling of model predictive control and robust Kalman filtering
Authors: Zenere Alberto , Zorzi Mattia
Published: April 2018

Model predictive control (MPC) represents nowadays one of the main methods employed for process control in industry. Its strong suits comprise a simple algorithm based on a straightforward formulation and the flexibility to deal with constraints. On the other hand, it can be questioned its robustness regarding model uncertainties and external noises. Thus, a lot of efforts have been spent in the past years into the search of methods to address these shortcomings. In this study, the authors propose a robust MPC controller which stems from the idea of adding robustness in the prediction phase of the algorithm while leaving the core of MPC untouched. More precisely, they consider a robust Kalman filter that has been recently introduced and they further extend its usability to feedback control systems. Overall the proposed control algorithm allows to maintain all of the advantages of MPC with an additional improvement in performance and without any drawbacks in terms of computational complexity. To test the actual reliability of the algorithm, they apply it to control a servomechanism system characterised by non‐linear dynamics.
Non‐linear FIR smoothing filter for systems with a modelling error and its application to the DR/GPS integrated navigation
Authors: Cho Seong Yun
Published: April 2018

Infinite impulse response (IIR) filter generally used in estimation, positioning, etc. has problems in that, when there is a modeling error even if the system is completely observable, the estimates may converge to incorrect values or the varying values cannot be estimated quickly. The finite impulse response (FIR) filter, which has been investigated as a method to solve this problem, has faster estimation performance than the IIR filter in the presence of modelling error, but there is a limit to the convergence characteristic of the state variables. In this paper, a non‐linear FIR smoothing (NFS) filter is proposed to overcome the limitation of the state variable convergence characteristic of the FIR filter. The proposed NFS filter adds the smoothing concept to the modified receding horizon Kalman FIR filter. In order to verify the performance of the NFS filter, this filter is applied to a delay‐tolerant integrated navigation system using magnetic compass (MC) of which error is difficult to be modelled accurately. If an un‐modeled jump or ramp error occurs in the MC measurement, it shows that the NFS filter can estimate the measurement error more accurately than the FIR filter as well as the IIR filter through a simulation.
Core rotation braking on the red giant branch for various mass ranges
Authors: Gehan C , Mosser B. , Michel E. , Samadi R. , Kallinger T.
Published: April 2018

Context. Asteroseismology allows us to probe stellar interiors. In the case of red giant stars, conditions in the stellar interior are such as to allow for the existence of mixed modes, consisting in a coupling between gravity waves in the radiative interior and pressure waves in the convective envelope. Mixed modes can thus be used to probe the physical conditions in red giant cores. However, we still need to identify the physical mechanisms that transport angular momentum inside red giants, leading to the slow-down observed for red giant core rotation. Thus large-scale measurements of red giant core rotation are of prime importance to obtain tighter constraints on the efficiency of the internal angular momentum transport, and to study how this efficiency changes with stellar parameters.

Aims. This work aims at identifying the components of the rotational multiplets for dipole mixed modes in a large number of red giant oscillation spectra observed by Kepler. Such identification provides us with a direct measurement of the red giant mean core rotation.

Methods. We compute stretched spectra that mimic the regular pattern of pure dipole gravity modes. Mixed modes with the same azimuthal order are expected to be almost equally spaced in stretched period, with a spacing equal to the pure dipole gravity mode period spacing. The departure from this regular pattern allows us to disentangle the various rotational components and therefore to determine the mean core rotation rates of red giants.

Results. We automatically identify the rotational multiplet components of 1183 stars on the red giant branch with a success rate of 69% with respect to our initial sample. As no information on the internal rotation can be deduced for stars seen pole-on, we obtain mean core rotation measurements for 875 red giant branch stars. This large sample includes stars with a mass as large as 2.5 M⊙, allowing us to test the dependence of the core slow-down rate on the stellar mass.

Conclusions. Disentangling rotational splittings from mixed modes is now possible in an automated way for stars on the red giant branch, even for the most complicated cases, where the rotational splittings exceed half the mixed-mode spacing. This work on a large sample allows us to refine previous measurements of the evolution of the mean core rotation on the red giant branch. Rather than a slight slow-down, our results suggest rotation is constant along the red giant branch, with values independent of the mass.
Topology-based description of the NCA cathode configurational space and an approach of its effective reduction
Authors: Zolotarev Pavel , Eremin Roman
Published: April 2018

Modification of existing solid electrolyte and cathode materialsis a topic of interest for theoreticians and experimentalists. In particular, itrequires elucidation of the influence of dopants on the characteristics of thestudying materials. For the reason of high complexity of theconfigurational space of doped/deintercalated systems, application of thecomputer modeling approaches is hindered, despite significant advances ofcomputational facilities in last decades. In this study, we propose a scheme,which allows to reduce a set of structures of a modeled configurationalspace for the subsequent study by means of the time-consuming quantumchemistry methods. Application of the proposed approach is exemplifiedthrough the study of the configurational space of the commercialLiNi0.8Co0.15Al0.05O2 (NCA) cathode material approximant.

The effect of simplifications of a numerical mesh on the results of electromagnetic analysis of the Nuclotron-type cable
Authors: Tomków Łukasz
Published: April 2018

The model of a single Nuclotron-type cable is presented. The goal of this model is to assess the behaviour of the cable under different loads. Two meshes with different simplifications are applied. In the first case, the superconductor in the cable is modelled as single region. Second mesh considers individual strands of the cable. The significant differences between the distributions of the electric current density obtained with both models are observed. The magnetic field remains roughly similar.
Quark-hadron phase structure of QCD matter from SU(4) Polyakov linear sigma model
Authors: DIAB Abdel Magied Abdel Aal , TAWFIK Abdel Nasser
Published: April 2018

The SU(4) Polyakov linear sigma model (PLSM) is extended towards characterizing the chiral condensates, σl, σs and σc of light, strange and charm quarks, respectively and the deconfinement order-parameters φ and φ at finite temperatures and densities (chemical potentials). The PLSM is considered to study the QCD equation of state in the presence of the chiral condensate of charm for different finite chemical potentials. The PLSM results are in a good agreement with the recent lattice QCD simulations. We conclude that, the charm condensate is likely not affected by the QCD phase-transition, where the corresponding critical temperature is greater than that of the light and strange quark condensates.
Confinement, Chiral Symmetry Breaking and it's Restoration using Dual QCD Formalism
Authors: Punetha Garima , Chandola H.C.
Published: April 2018

Utilizing the dual QCD model in term of magnetic symmetry structure of non- Abelian gauge theories, the dynamical chiral-symmetry breaking using Schwinger-Dyson equation has been investigated. A close relation among the color confinement and chiralsymmetry breaking has been observed and demonstrated by computing dynamical parameters. The recovery of the chiral symmetry has also been discussed at finite temperature through the variation of quark mass function and quark condensate which gradually decreases with temperature and vanishes suddenly near the critical temperature.

Published: April 2018

In this contribution, we want to summarize recent development steps of the embedded cognitive user interface UCUI, which enables a user-adaptive scenario in human-machine or even human-robot interactions by considering sophisticated cognitive and semantic modelling. The interface prototype is developed by different German institutes and companies with their steering teams at Fraunhofer IKTS and Brandenburg University of Technology. The interface prototype is able to communicate with users via speech and gesture recognition, speech synthesis and a touch display. The device includes an autarkic semantic processing and beyond a cognitive behavior control, which supports an intuitive interaction to control different kinds of electronic devices, e. g. in a smart home environment or in interactive respectively collaborative robotics. Contrary to available speech assistance systems such as Amazon Echo or Google Home, the introduced cognitive user interface UCUI ensures the user privacy by processing all necessary information without any network access of the interface device.

La différenciation par l’organisation de filières : l’expérience d’AGROPOL
Authors: Le Guilloux Guénaël , David Augustin , Pouzet André
Published: April 2018

Agropol, association des membres de la filière oléo-protéagineuse française et de ses partenaires, accompagne le développement des filières oléagineuses en dehors du territoire national, en accord avec la conviction que le schéma interprofessionnel tel qu’il est mis en œuvre en France peut également contribuer à répondre aux grands défis de l’Afrique : sécurité alimentaire, réduction de la pauvreté et durabilité des exploitations agricoles familiales. Deux exemples d’intervention d’AGROPOL sont présentés : l’accompagnement du développement des cultures de colza et de tournesol dans le cadre du Plan Vert Marocain et le projet de développement du soja au Burkina-Faso. L’analyse de ces expériences se fait selon la trame définie dans un accord de partenariat avec la FAO en 2012. Il résulte de l’analyse des deux expériences que la réussite de l’action interprofessionnelle permet la création de valeur et la différenciation des acteurs. Elle repose bien sûr sur une organisation en filière pour répondre à la demande d’un marché, une gouvernance basée sur une concertation permanente entre les différents acteurs, et un partage des orientations avec les pouvoirs publics, mais le facteur le plus sensible est certainement l’efficacité de l’organisation des producteurs dans le temps, tant au niveau local qu’au niveau national.
Le sourire : un enjeu dans la décision thérapeutique des classes III
Authors: De Launay Laure , Gebeile-Chauty Sarah
Published: April 2018

Introduction :Le sourire représente un challenge dans la prise en charge des classes III. Sans traitement, le sujet en classe III présente un torque maxillaire excessif et découvre majoritairement les incisives mandibulaires, signe qui s’accentue avec l’âge. L’orthopédie fonctionnelle permet de restaurer le caractère esthétique du sourire par protraction maxillaire (parfois provisoirement car 20 % des cas auront quand même besoin d’une chirurgie). Selon la sévérité initiale du cas (−4,5 mm d’AoBo constitueraient la valeur seuil), les options sont la compensation ou la correction chirurgicale. Dans les deux cas, le profil est amélioré, mais sans pour autant obtenir une normalisation des valeurs céphalométriques. Ces dernières années, les publications de cas traités par compensations (souvent par ancrage osseux) se sont multipliées avec des indications plus larges, en particulier pour les patients asiatiques pour lesquels la chirurgie de Le Fort I donne des résultats esthétiques discutables. L’attention doit alors être portée sur la bascule du plan d’occlusion, laquelle altère le sourire par la visibilité des incisives mandibulaires. Néanmoins, la chirurgie permet de gérer les cas les plus sévères avec une proportion d’amélioration plus importante.Objectif :L’objectif de cet article est de rechercher, par l’analyse de la littérature, les valeurs limites céphalométriques pour un sourire acceptable des patients en classe III.Matériels et méthodes :Nous avons effectué une recherche sur Pubmed à partir de mots clés :class III, anterior cross bite, smile, camouflage, orthognathic surgery, puis secondairement à partir des références fournies par les articles trouvés et avons analysé les données.Résultats :Le protocole ortho-chirurgical associé aux extractions de premières prémolaires maxillaires serait le moyen d’obtenir les meilleurs résultats en termes de sourire (versusla chirurgie sans extractions etversusles compensations orthodontiques) car c’est, en effet, le seul moyen de rétablir une position et un torque normalisés des incisives maxillaires, ce qui augmente leur visibilité lors du sourire.
Usage multiple des ancrages squelettiques : mise à profit des mini-vis d’ancrage pour améliorer l’esthétique lors du traitement actif et lors de la contention
Authors: Renger Stéphane , Gremeret Mélanie , Gebeile-Chauty Sarah
Published: April 2018

Introduction : Les principaux échecs de tractions canines sont dus à un défaut d’ancrage, une direction de traction inadéquate, une force non contrôlée. Une adolescente (10 ans et 9 mois) se présente avec 13 et 23 incluses en position palatine ; 12 et 22 présentent une anomalie de taille par défaut. Deux mini-vis, insérées en mésio-palatin de 16 et 26, permettent de sécuriser la traction de 13 et 23, l’appareil multi-attache n’étant installé que dans un second temps. Après la dépose du multi-attache, les mini-vis sont laissées en place. Elles permettent d’assurer la contention en stabilisant la plaque palatine, d’éviter arcs et crochets métalliques parfois sources d’instabilités occlusales et souvent inesthétiques lors du sourire. Discussion : Les alternatives sont discutées : Ballista spring, mini-vis fixée dans la suture palatine, arc de Nance… Conclusion : L’utilisation à des fins multiples des ancrages squelettiques temporaires lors de traction de canine incluse palatine (spécifiquement dans les cas d’inclusions bilatérales) ouvre des possibilités intéressantes en sécurisant le déplacement canin, en permettant de s’affranchir quasiment de la coopération du patient (absence de perte d’ancrage antéro-postérieure). Le confort du patient (diminution de l’encombrement lié à l’appareil) et celui de son praticien (activations facilitées) sont ainsi augmentés. La durée globale de traitement avec multi-attache peut être diminuée et la contention est rendue plus efficace et plus esthétique lors du sourire.
Plasmodium falciparum resistance to artemisinin-based combination therapies: A sword of Damocles in the path toward malaria elimination
Authors: Ouji Manel , Augereau Jean-Michel , Paloque Lucie , Benoit-Vical Françoise
Published: April 2018

The use of artemisinin-based combination therapies (ACTs), which combine an artemisinin derivative with a partner drug, in the treatment of uncomplicated malaria has largely been responsible for the significant reduction in malaria-related mortality in tropical and subtropical regions. ACTs have also played a significant role in the 18% decline in the incidence of malaria cases from 2010 to 2016. However, this progress is seriously threatened by the reduced clinical efficacy of artemisinins, which is characterised by delayed parasitic clearance and a high rate of recrudescence, as reported in 2008 in Western Cambodia. Resistance to artemisinins has already spread to several countries in Southeast Asia. Furthermore, resistance to partner drugs has been shown in some instances to be facilitated by pre-existing decreased susceptibility to the artemisinin component of the ACT. A major concern is not only the spread of these multidrug-resistant parasites to the rest of Asia but also their possible appearance in Sub-Saharan Africa, the continent most affected by malaria, as has been the case in the past with parasite resistance to other antimalarial treatments. It is therefore essential to understand the acquisition of resistance to artemisinins by Plasmodium falciparum to adapt malaria treatment policies and to propose new therapeutic solutions.

Authors: Couzon F. , Gulyayeva Nsair L. , Russel Robillard A.S.
Published: April 2018

Objectifs : Le but de cette étude est la mise en place d’une démarche d’optimisation des doses aux patients en radiologie pédiatrique lors des cystographies et transits oeso-gastroduodénal. Matériels et méthodes : La démarche d’optimisation a débuté par une évaluation des niveaux d’exposition basée sur 87 cystographies et 70 TOGD. Les procédés d’optimisation des doses ont ensuite été testés sur fantôme (les tensions appliquées, les géométries de cellules, les cadences images et le retrait de la grille anti-diffusante) afin de s’assurer d’une qualité d’images acceptable pour le diagnostic. Une seconde évaluation dosimétrique (99 relevés pour la cystographie et 59 pour le TOGD) a permis d’estimer les diminutions d’exposition obtenues. Résultats : Pour les 3 tranches d’âge (0–4 mois, 4–23 mois et 2–10 ans), les PDS médians ont été réduits respectivement d’un facteur 6, 2,9 et 2,3 pour la cystographie et de 2,8, 1,4 et 2 pour le TOGD. Conclusion : Cette démarche a permis des diminutions de doses significatives pour ces deux examens réalisés en radio-pédiatrie. La qualité des images radiologiques a été maintenue à un niveau permettant la réalisation du geste ainsi que son interprétation. Enfin, nos recueils dosimétriques pourront éventuellement s’intégrer dans une future étude nationale sur les niveaux d’exposition en pédiatrie.

Environmental identity: “space” vs “place”
Authors: Lekus Elena
Published: April 2018

The article considers the problem of environmental identity, which is one of the most important criteria for the quality of the city's light environment. It is argued that a city’s sustainable development means creating conditions for the process of identifying its inhabitants, transforming the concept of the city as a "space" into the concept of the city as a “place”. There are a number of important socio-cultural trends that form the lighting culture of the modern city.
Educational complex of light-colored modeling of urban environment
Authors: Karpenko Vladimir E.
Published: April 2018

Mechanisms, methodological tools and structure of a training complex of light-colored modeling of the urban environment are developed in this paper. The following results of the practical work of students are presented: light composition and installation, media facades, lighting of building facades, city streets and embankment. As a result of modeling, the structure of the light form is determined. Light-transmitting materials and causing characteristic optical illusions, light-visual and light-dynamic effects (video-dynamics and photostatics), basic compositional techniques of light form are revealed. The main elements of the light installation are studied, including a light projection, an electronic device, interactivity and relationality of the installation, and the mechanical device which becomes a part of the installation composition. The meaning of modern media facade technology is the transformation of external building structures and their facades into a changing information cover, into a media content translator using LED technology. Light tectonics and the light rhythm of the plastics of the architectural object are built up through point and local illumination, modeling of the urban ensemble assumes the structural interaction of several light building models with special light-composition techniques. When modeling the social and pedestrian environment, the lighting parameters depend on the scale of the chosen space and are adapted taking into account the visual perception of the pedestrian, and the atmospheric effects of comfort and safety of the environment are achieved with the help of special light compositional techniques. With the aim of realizing the tasks of light modeling, a methodology has been created, including the mechanisms of models, variability and complementarity. The perspectives of light modeling in the context of structural elements of the city, neuropsychology, wireless and bioluminescence technologies are proposed. Conclusions are given on the environment-forming and transforming significance of artificial light and light technologies in the space of modern city. Light-colored modeling identity is expressed in methodical and figurative-artistic continuity in the use of techniques of light composition and optical art. The use of light composition contributes to the expression of local identity by means and techniques of light composition in the context of the image, “genius loci” using the example of the Vladivostok seaside city. Identity in psychology is expressed in the personal selection of the techniques of light composition, which are used in light-colored modeling.

The swimrun is a new endurance team-sport based on two persons swimming and running alternatively through open water and mostly trails. The aim of this study was to analyse participation and performance trends for males, females and mixed duo team at the ÖTILLÖ Swimrun race (10 km open-water swimming and 65 km trail running). During the 2012–2016 period, the mean total time performance of the best athletes at the ÖTILLÖ Swimrun decreased significantly by 17 min/year for males, 40 min/year for mixed and 59 min/year for females duo, respectively. The difference in performance between the best males and females duo (26 ± 15%) was significantly greater compared to the difference between males and mixed duo (12 ± 8%). The number of swimrun races organized across the world has dramatically increased these last years and will probably continue to grow up in the future. Swimrun athletes are still not very experienced, thus both improvements in performance and reduction in sex difference are expected in the next decade.

Background To determine the prevalence of congenital CMV infection (cCMV) in very-low-birth-weight infants (VLBWI) and to evaluate epidemiological characteristics of VLBWI with antiviral therapy (AT).

Methods CMV-specific PCR in umbilical cord tissue was performed (n=3330). Univariate analyses and logistic regression models were used to identify associations with outcome.

Results 22/3330 VLBWI received AT (0.66%). 4 of these (0.12%) were PCR positive, with 2 VLBWI showing pathological screening for hearing loss. VLBWI with AT and negative PCR had significantly reduced mean birth weight (BW) and higher rates of small-for-gestational-age (SGA). Clinical sepsis, bronchopulmonary dysplasia (BPD), use of reserve antibiotics (RA) and treatment for retinopathy of prematurity were significantly increased. We further observed a higher need of transfusion of red blood cells (RBC), fresh frozen plasma and platelets. Logistic regression (controlled for gender, gestational age, SGA and BW) showed associations for AT and BPD (OR 3.4 [1.2–10.1], p=0.024), RA (OR 20.4 [4.2–98.9], p≤0.001), transfusions of RBC (OR 11.9 [1.3–105.7], p=0.026) and platelets (OR 8.7 [2.9–26.4], p≤0.001).

Discussion All VLBWI with positive PCR received AT. We hypothesize from our data by assuming a postnatal aquired CMV infection in VLBWI with AT and negative PCR that VLBWI born SGA have a different risk profile.

Conclusion Further prospective studies concerning postnatal transmission should take VLBWI born SGA into account and should study the impact of infection on short- and long-term complications in this supposed vulnerable group.

Published: April 2018

An enantioselective Michael addition of diphenyl phosphonate to nitroalkenes has been developed by using a secondary amine bisthiourea catalyst to access enantiomerically enriched β-nitro phosphonates. In this reaction, molecular sieves play a key role in achieving high and reproducible yields with a high enantioselectivities of up to 99% at –10 °C. A probable mechanism for the enantioselective Michael addition reaction was established by means of an NMR spectroscopic study.

Published: April 2018

In this study, we present results from electrical, optical, and spectroscopic diagnosis of a short-pulse (250 ns) high-power impulse (up to 11 kW) dielectric barrier discharge at atmospheric pressure running in a helium/helium-hydrogen/helium-hydrogen-methane gas mixture. This plasma source is able to generate up to 20 cm3 of plasma volume, pulsed in kilohertz range. The plasma spatio-temporal dynamics are found to be developed in three distinct phases. All the experimental observations reveal a similar dynamic to medium power microsecond barrier discharges, although the power per pulse and current density are up to two orders of magnitude higher than the case of microsecond barrier discharges. This might open the possibility for new applications in the field of gas or surface processing, and even life science. These devices can be used in laboratory experiments relevant for molecular astrophysics.
Effectively parameterizing dissipative particle dynamics using COSMO-SAC: A partition coefficient study
Authors: Saathoff Jonathan
Published: April 2018

Dissipative Particle Dynamics (DPD) provides a tool for studying phase behavior and interfacial phenomena for complex mixtures and macromolecules. Methods to quickly and automatically parameterize DPD greatly increase its effectiveness. One such method is to map predicted activity coefficients derived from COSMO-SAC onto DPD parameter sets. However, there are serious limitations to the accuracy of this mapping, including the inability of single DPD beads to reproduce asymmetric infinite dilution activity coefficients, the loss of precision when reusing parameters for different molecular fragments, and the error due to bonding beads together. This report describes these effects in quantitative detail and provides methods to mitigate much of their deleterious effects. This includes a novel approach to remove errors caused by bonding DPD beads together. Using these methods, logarithm hexane/water partition coefficients were calculated for 61 molecules. The root mean-squared error for these calculations was determined to be 0.14—a very low value—with respect to the final mapping procedure. Cognizance of the above limitations can greatly enhance the predictive power of DPD.
Scalable and reusable micro-bubble removal method to flatten large-area 2D materials

Published: April 2018

Bubbles generated during electro-delamination and chemical etch during large-area two-dimensional (2D) material transfer has been shown to cause rippling, and consequently, results in tears and wrinkles in the transferred film. Here, we demonstrate a scalable and reusable method to remove surface adhered micro-bubbles by using hydrophobic surfaces modified by self-assembled monolayers (SAMs). Bubble removal allows the 2D film to flatten out and prevents the formation of defects. Electrical characterization was used to verify improved transfer quality and was confirmed by increased field-effect mobility and decreased sheet resistance. Raman spectroscopy was also used to validate enhanced electrical quality following transfer. The bubble removal method can be applied to an assortment of 2D materials using diverse hydrophobic SAM variants. Our studies can be integrated into large scale applications and will lead to improved large-area 2D electronics in general.

Published: April 2018

The terahertz band holds a potential for point-to-point short-range wireless communications at sub-terabit speed. To realize this potential, supporting antennas must have a wide bandwidth to sustain high data rate and must have high gain and low dissipation to compensate for the free space path loss that scales quadratically with frequency. Here we propose an all-dielectric rod antenna array with high radiation efficiency, high gain, and wide bandwidth. The proposed array is integral to a low-loss photonic crystal waveguide platform, and intrinsic silicon is the only constituent material for both the antenna and the feed to maintain the simplicity, compactness, and efficiency. Effective medium theory plays a key role in the antenna performance and integrability. An experimental validation with continuous-wave terahertz electronic systems confirms the minimum gain of 20 dBi across 315–390 GHz. A demonstration shows that a pair of such identical rod array antennas can handle bit-error-free transmission at the speed up to 10 Gbit/s. Further development of this antenna will build critical components for future terahertz communication systems.
