Endocannabinoid signaling in social functioning: an RDoC perspective
Authors: Karhson D S , Hardan A Y , Parker K J
Published: September 2016

Core deficits in social functioning are associated with various neuropsychiatric and neurodevelopmental disorders, yet biomarker identification and the development of effective pharmacological interventions has been limited. Recent data suggest the intriguing possibility that endogenous cannabinoids, a class of lipid neuromodulators generally implicated in the regulation of neurotransmitter release, may contribute to species-typical social functioning. Systematic study of the endogenous cannabinoid signaling could, therefore, yield novel approaches to understand the neurobiological underpinnings of atypical social functioning. This article provides a critical review of the major components of the endogenous cannabinoid system (for example, primary receptors and effectors—Δ9-tetrahydrocannabinol, cannabidiol, anandamide and 2-arachidonoylglycerol) and the contributions of cannabinoid signaling to social functioning. Data are evaluated in the context of Research Domain Criteria constructs (for example, anxiety, chronic stress, reward learning, motivation, declarative and working memory, affiliation and attachment, and social communication) to enable interrogation of endogenous cannabinoid signaling in social functioning across diagnostic categories. The empirical evidence reviewed strongly supports the role for dysregulated cannabinoid signaling in the pathophysiology of social functioning deficits observed in brain disorders, such as autism spectrum disorder, schizophrenia, major depressive disorder, posttraumatic stress disorder and bipolar disorder. Moreover, these findings indicate that the endogenous cannabinoid system holds exceptional promise as a biological marker of, and potential treatment target for, neuropsychiatric and neurodevelopmental disorders characterized by impairments in social functioning.

Published: September 2016

Chronic traumatic encephalopathy (CTE) is a neurodegenerative disorder most commonly associated with repetitive traumatic brain injury (TBI) and characterized by the presence of neurofibrillary tangles of tau protein, known as a tauopathy. Currently, the diagnosis of CTE can only be definitively established postmortem. However, a new positron emission tomography (PET) ligand, [18F]T807/AV1451, may provide the antemortem detection of tau aggregates, and thus various tauopathies, including CTE. Our goal was to examine [18F]T807/AV1451 retention in athletes with neuropsychiatric symptoms associated with a history of multiple concussions. Here we report a 39-year-old retired National Football League player who suffered 22 concussions and manifested progressive neuropsychiatric symptoms. Emotional lability and irritability were the chief complaints. Serial neuropsychological exams revealed a decline in executive functioning, processing speed and fine motor skills. Naming was below average but other cognitive functions were preserved. Structural analysis of longitudinally acquired magenetic resonance imaging scans revealed cortical thinning in the left frontal and lateral temporal areas, as well as volume loss in the basal ganglia. PET with [18F]florbetapir was negative for amyloidosis. The [18F]T807/AV1451 PET showed multifocal areas of retention at the cortical gray matter–white matter junction, a distribution considered pathognomonic for CTE. [18F]T807/AV1451 standard uptake value (SUV) analysis showed increased uptake (SUVr⩾1.1) in bilateral cingulate, occipital, and orbitofrontal cortices, and several temporal areas. Although definitive identification of the neuropathological underpinnings basis for [18F]T807/AV1451 retention requires postmortem correlation, our data suggest that [18F]T807/AV1451 tauopathy imaging may be a promising tool to detect and diagnose CTE-related tauopathy in living subjects.

The role of the mtDNA set point in differentiation, development and tumorigenesis
Authors: Sun Xin , St. John Justin C.
Published: September 2016

Mitochondrial DNA replication is critical for maintaining mtDNA copy number to generate sufficient cellular energy that is required for development and for functional cells. In early development, mtDNA copy number is strictly regulated at different stages, and, as a result, the establishment of the mtDNA set point is required for sequential cell lineage commitment. The failure to establish the mtDNA set point results in incomplete differentiation or embryonic arrest. The regulation of mtDNA copy number during differentiation is closely associated with cellular gene expression, especially with the pluripotency network, and DNA methylation profiles. The findings from cancer research highlight the relationship between mitochondrial function, mtDNA copy number and DNA methylation in regulating differentiation. DNA methylation at exon 2 of DNA polymerase gamma subunit A (POLGA) has been shown to be a key factor, which can be modulated to change the mtDNA copy number and cell fate of differentiating and tumour cells. The present review combines multi-disciplinary data from mitochondria, development, epigenetics and tumorigenesis, which could provide novel insights for further research, especially for developmental disorders and cancers.
The role of TREX in gene expression and disease
Authors: Heath Catherine G. , Viphakone Nicolas , Wilson Stuart A.
Published: September 2016

TRanscription and EXport (TREX) is a conserved multisubunit complex essential for embryogenesis, organogenesis and cellular differentiation throughout life. By linking transcription, mRNA processing and export together, it exerts a physiologically vital role in the gene expression pathway. In addition, this complex prevents DNA damage and regulates the cell cycle by ensuring optimal gene expression. As the extent of TREX activity in viral infections, amyotrophic lateral sclerosis and cancer emerges, the need for a greater understanding of TREX function becomes evident. A complete elucidation of the composition, function and interactions of the complex will provide the framework for understanding the molecular basis for a variety of diseases. This review details the known composition of TREX, how it is regulated and its cellular functions with an emphasis on mammalian systems.
Speech Movement Measures as Markers of Bulbar Disease in Amyotrophic Lateral Sclerosis
Authors: Shellikeri Sanjana , Green Jordan R. , Kulkarni Madhura , Rong Panying , Martino Rosemary , Zinman Lorne , Yunusova Yana
Published: September 2016

Purpose

The goal of this study was to identify the effects of amyotrophic lateral sclerosis (ALS) on tongue and jaw control, both cross-sectionally and longitudinally. The data were examined in the context of their utility as a diagnostic marker of bulbar disease.

Method

Tongue and jaw movements were recorded cross-sectionally (n= 33 individuals with ALS, 13 controls) and longitudinally (n= 10 individuals with ALS) using a three-dimensional electromagnetic articulography system during the production of the sentenceBuy Bobby a puppy.The movements were examined for evidence of changes in size, speed, and duration and with respect to disease severity and time in the study.

Results

Maximum speed of tongue movements and movement durations were significantly different only at an advanced stage of bulbar ALS compared with the healthy control group. The longitudinal analysis revealed a reduction in tongue movement size and speed with time at early stages of disease, which was not seen cross-sectionally. As speaking rate declined, tongue movements decreased in maximum speed, whereas jaw movements increased in maximum speed.

Conclusions

Longitudinal analyses of sentence-level kinematic data show their sensitivity to early bulbar impairment. A change in articulatory kinematics can serve as a useful diagnostic marker for bulbar ALS and to track bulbar disease progression in a clinical setting.
Bilingual and Home Language Interventions With Young Dual Language Learners: A Research Synthesis
Authors: Durán Lillian K. , Hartzheim Daphne , Lund Emily M. , Simonsmeier Vicki , Kohlmeier Theresa L.
Published: September 2016

Purpose

The purpose of this systematic review was to determine what bilingual or home language interventions have been found to be effective for 2- to 6-year-old dual language learners who have language impairment (LI) or are at risk for LI.

Method

We conducted ancestral searches and searches of electronic databases, hand-searched article bibliographies, and searched 19 journals for experimental, quasiexperimental, or single-subject studies.

Results

The review yielded 26 studies that were coded for quality, frequency and duration of the intervention, number of participants, location of intervention, interventionist, language(s) of intervention, and reported or calculated effect sizes. Studies were grouped by those that focused specifically on at-risk populations and those that focused on children with LI. Emerging trends provide support for bilingual and/or home language interventions for both children with LI and those at risk for LI.

Conclusions

There were relatively few studies that met inclusion criteria, and the average quality rating for a study was 6.8 out of 9.0 possible points. More high-quality research is needed, particularly with populations that speak languages other than Spanish. Clinicians need more evidence-based recommendations to improve the language and literacy outcomes of the diverse range of dual language learners served in the United States and abroad.
Hybrid three‐level PWM and resonant converter
Authors: Lin B.R.
Published: September 2016

A hybrid soft‐switching converter including two resonant circuits and an un‐regulated dc–dc pulse‐width modulation (PWM) circuit is presented. Two split capacitors with four active switches are used at primary side to limit power switches at Vin/2. The variable frequency operation is adopted to regulate output voltage. Two flying capacitors are also adopted at the primary side to automatically balance two input split voltages. One un‐regulated PWM converter shared the same power switches of two resonant circuits is used to reduce the output current ripple. Therefore, the power rating of power semiconductors and passive components are reduced. The operation principles, performance and effectiveness are illustrated and verified on a 1.44 kW (48 V/30 A) prototype circuit.
Optimisation of chaos‐based coded modulations for compensation of amplifier non‐linearities

Published: September 2016

The possibilities of a known class of chaos‐based coded modulation (CCM) systems are expanded to address the problem of high‐power amplifier (HPA) non‐linearity. The hypothesis is that the CCM non‐linear nature can be exploited to counteract its effects on the system perfomance, avoiding the need of a predistorter. An optimisation method for the design of the CCM to prove this hypothesis is proposed. The results show that, for a given back‐off level, a non‐linear mapping function for the chaos‐based encoder and decoder can be designed to compensate the HPA effect on the error rate.

Published: September 2016

Visible light communication (VLC) system based on orthogonal frequency division multiplexing (OFDM) is promising for its ability to link a huge number of devices with high reliability and low latency. However, OFDM‐based VLC systems are very sensitive to the symbol timing offsets. Thus, synchronisation algorithm is very important for OFDM‐based VLC system. In this study, the authors first propose zero correlation code pair (ZCC pair) and investigate the periodical impulse‐shaped correlation property of ZCC pair. Then the authors propose a novel timing offset estimation algorithm based on ZCC pair. The preamble is processed via peak‐to‐average power ratio (PAPR) reduction algorithms to overcome the PAPR problem in VLC systems. This algorithm achieves high accuracy and has low synchronisation error probability. The effectiveness of the authors’ proposed algorithm has been demonstrated using computer simulation under non‐light‐of‐sight VLC and Gaussian channels. The results show that the authors’ algorithm outperforms the Schmidl Cox's and Park's algorithms in terms of synchronisation error probability and mean square error of timing error.

Authors: Guo Yuxiang , Ma Baoli , Chen Liping , Wu Ranchao
Published: September 2016

This study is concerned with the stabilisation problem for a class of Caputo type fractional‐order interval systems with perturbation. Employing Riemann–Liouville fractional integral sliding surface, a novel robust sliding mode control law is established to drive the dynamics of the system to the manifold s =0 in finite time. Based on linear matrix inequality criterions and stability theorems, the closed‐loop system will asymptotically converge to the origin as time progresses. Meanwhile, the unknown perturbation is well adjusted on‐line by the designed adaptive law. Furthermore, a new reaching law is introduced to reduce the chattering which is caused by the discontinuity of the switching function, and to improve the robustness and the stability of system. Besides, some results about the control and stabilisation of fractional‐order interval systems are illustrated in this study; several comparisons with the related works are given to reveal the potential advantages of the proposed controller over the previous results. Finally, an example with numerical simulations is provided to show the validity and feasibility of the proposed method.
Synchronisation of stochastic delayed multi‐agent systems with uncertain communication links and directed topologies
Authors: Wang Fan , Liang Jinling , Huang Tingwen
Published: September 2016

This study investigates the mean square exponential (MSE) synchronisation problem for the multi‐agent systems with multiplicative noises, where the communication topologies among the agents are directed and time varying. The phenomenon of randomly varying coupling delay is considered and described by a Bernoulli distributed white sequence with known probability, thereby better reflecting the practical system dynamics. Network topologies proposed in this study are directed and time varying which intrinsically characterise the random communications between agents. By exploiting the graph theory and the coordinate transformation method, the MSE synchronisation problem for the stochastic multi‐agent network is converted into a robust MSE stability problem for the transformed system. Then by constructing a Lyapunov functional and utilising the properties of Kronecker product, both delay‐independent and delay‐dependent sufficient conditions are derived guaranteeing the transform system to be robustly stable in the mean square. The criteria established are in the form of matrix inequalities which can be solved and checked easily. Finally, simulation examples are provided to illustrate the validity for the obtained results.

Published: September 2016

This study presents integration of transistor based inductive source degeneration and specially shielded transformer into a millimetre‐wave power amplifier (mm‐wave PA) operating at wideband. A new configuration of high Q distributed inductor is devised and embedded in CMOS transistor source to enhance stability, maximum stable gain and bandwidth of mm‐wave CMOS PAs. The source inductance selection is conveniently investigated by the proposed admittance matrix condensation. In power splitting and combining part, a novel X‐shape pattern‐ground shielding is inserted in high turn ratio transformer to ameliorate wideband matching. Based on these techniques, a fully differential mm‐wave PA was implemented in 65 nm low‐power CMOS with 0.25 mm2 core area. The measurement results show that its differential drive gain and common mode rejection ratio are above 10 and 26 dB, respectively, in a wide frequency range of 41 to 61 GHz, while the power added efficiency (PAE) is still above 10.8% at 46–62 GHz. This CMOS PA also achieves 11.9 dBm output referred 1‐dB compression point (P1 dB) and 15.2 dBm saturated power (Psat) with 12.4% peak PAE.
Analysis of lossy multiconductor transmission lines and application of a crosstalk cancelling algorithm
Authors: Ianconescu Reuven , Vulfin Vladimir
Published: September 2016

The authors showed in a previous work that it is possible to transmit N signals without crosstalk or return loss through a lossless multiconductor transmission line (MTL) of N + 1 conductors. Such algorithm can increase the data rate twice (in the absence of noise), relative to the usual transmission of differential signals. In this work, they analyse lossy MTLs and test the above algorithm on the lossy lines.
Comment on ‘Wide‐angle broadband microwave metamaterial absorber with octave bandwidth’
Authors: Kundu Debidas , Mohan Akhilesh , Chakrabarty Ajay
Published: September 2016

This comment demonstrates that in a recent study by Bhattacharyya et al., a linear reflective polarisation converter is erroneously interpreted as broadband absorber. It is clearly shown that the incident electromagnetic wave is reflected with its orthogonal polarisation state due to which co‐polarised reflection is reduced. Total absorption, when both the co‐ and cross‐polarised reflected components are considered, is less than 20% in the operating band claimed by the authors.
Fabrication of atomic force microscope spherical tips and its application in determining the mechanical property of cancer cells
Authors: Han Yimin , Wang Jinghe , Wang Kui , Dong Shen
Published: September 2016

The process of cancer metastasis is closely related to the mechanical property of cells. Using the atomic force microscope (AFM)‐based nanoindentation technique, the mechanical properties of cancer cells can be measured in liquid and at 37°C. However, the conventional AFM tip is too sharp to finish this process. The AFM tip with a microsphere at the end is usually used. How to adhere a microsphere to the tip apex has become a big concern up to now. In this work, an easy and simple method based on the employment of carbon nanotube bundles is presented. The microsphere is successfully adhered to the tip and the elastic constant of the cantilever is calibrated with the Cleveland method. Using the developed tip, the nanoindentation tests on two kinds of lung cancer cells (Anip‐973 and AGZY‐83a), which exhibit different metastatic properties, are carried out in liquid and at 37°C. Based on the Hertz contact equation between the spherical tip and the cell, the stress relaxation model is used to calculate the Young's modulus and viscoelastic properties of the cells. Experimental results confirm the feasibility of the method proposed in this work.
Controllable synthesis of SiO2 nanoparticles: effects of ammonia and tetraethyl orthosilicate concentration
Authors: Yan Yue , Fu Jie , Xu Ling , Wang Tianfu , Lu Xiuyang
Published: September 2016

SiO2 nanoparticles can be used as drug carriers in drug delivery systems, wherein the size of the nanoparticles plays a vital role in their distribution in vivo. SiO2 nanoparticles were synthesised using the Stöber method and characterised by dynamic light scattering and scanning electron microscopy. The effects of the ammonia concentration, tetraethyl orthosilicate (TEOS) concentration, water loading and alcohol type on the size and dispersion of the SiO2 nanoparticles were investigated. The results showed that the concentration of ammonia was the most important factor in dictating the size of the SiO2 nanoparticles. The size of the particles increased with increasing ammonia and TEOS concentrations. Increasing the water loading caused a reduction in the particle size but an increase in the dispersion. Both the particle size and dispersion increased with increasing alcohol carbon number. Linear relationships were observed between the SiO2 particle size and the concentrations of ammonia and TEOS, which could be used to control the size of SiO2 nanoparticles during synthesis.

Authors: Bae Inshik , Na Byungkeun , Chang Hongyoung
Published: September 2016

Widely used plasma types, such as capacitively coupled plasmas and inductively coupled plasmas, have been studied by several researchers, and their uses have been thoroughly explored. In contrast, electron beam plasmas have not been well studied in wide pressure or voltage ranges. Therefore, it is necessary to investigate their general characteristics, such as electron densities and temperatures. In this study, we focus on the electron mean free path and investigate the general characteristics, such as the electron density, temperature, plasma potential, and breakdown voltage, of a cylindrical plasma discharge with a thermal electron beam. An electron density of about 108–109 cm−3 and an electron temperature of 1–2 eV were obtained experimentally. The dependence of these parameters on the pressure and anode voltage is also investigated.
Full vectorial mapping of the complex electric near-fields of THz resonators
Authors: Bhattacharya Arkabrata , Gómez Rivas Jaime
Published: September 2016

Using micro-structured photo-conducting probes, we demonstrate full vectorial mapping of the complex electric fields in the near-field region of a resonant structure at THz frequencies. The investigated structure represents the simplest case of a resonator: a metallic rod. We show field amplitude as well as phase maps for the three field components at the half wavelength (λ/2) resonance of the rod. The field as well as the phase distributions are in excellent agreement with our physical understanding of local electric-field distributions in the vicinity of λ/2 resonant structures and are validated by numerical simulations. These measurements can be a platform for performance optimization of the emerging field of THz photonic and plasmonic devices with complex sub-wavelength structures.
Carbon membranes for efficient water-ethanol separation
Authors: Gravelle Simon , Yoshida Hiroaki , Joly Laurent , Ybert Christophe , Bocquet Lydéric
Published: September 2016

We demonstrate, on the basis of molecular dynamics simulations, the possibility of an efficient water-ethanol separation using nanoporous carbon membranes, namely, carbon nanotube membranes, nanoporous graphene sheets, and multilayer graphene membranes. While these carbon membranes are in general permeable to both pure liquids, they exhibit a counter-intuitive “self-semi-permeability” to water in the presence of water-ethanol mixtures. This originates in a preferred ethanol adsorption in nanoconfinement that prevents water molecules from entering the carbon nanopores. An osmotic pressure is accordingly expressed across the carbon membranes for the water-ethanol mixture, which agrees with the classic van’t Hoff type expression. This suggests a robust and versatile membrane-based separation, built on a pressure-driven reverse-osmosis process across these carbon-based membranes. In particular, the recent development of large-scale “graphene-oxide” like membranes then opens an avenue for a versatile and efficient ethanol dehydration using this separation process, with possible application for bio-ethanol fabrication.
