Optimisation study of power allocation and relay location for amplify‐and‐forward systems over Nakagami‐ m fading channels
Authors: Ikki Salama S. 
Published: October 2012

ABSTRACTWe consider power allocation (PA) and relay positioning in a dual‐hop amplify‐and‐forward relaying system over Nakagami‐m fading channels. We investigate adaptive PA with fixed relay location, optimal relay location with fixed PA, and joint optimisation of the PA and relay location under transmit power constraint in order to minimise average error probability and outage probability. Analytical results are validated by numerical simulations and comparisons between the different optimisation schemes and their performance are provided. Results show that optimum PA brings only coding gain, whereas optimum relay location yields, in addition to the latter, diversity gains as well. Also, joint optimisation improves both, the diversity gain and coding gain. Furthermore, results illustrate that the analysed adaptive algorithms outperform uniform schemes.

An ant colony‐based, receiver‐initiated multicast mesh protocol for collaborative applications of mobile ad hoc networks
Authors: Deepalakshmi P. , Radhakrishnan S. 
Published: October 2012

ABSTRACTMobile ad hoc (ODMRP), another mesh‐based multicast approach for mobile ad hoc networks in two scenarios, namely typical scenario and collaborative scenario. The simulation is carried out in NS‐2 and comparison is conducted for the metrics packet delivery ratio, group reliability ratio, and end‐to‐end average delay by varying node mobility and by increasing number of senders in each group. From the results, we observed that the proposed protocol performs well in all cases. Especially for collaborative scenarios in which number of senders is high within the group, RIMM outperforms ODMRP. Also, we observed that probability of reaching multicast members within the mesh is always high for RIMM than for ODMRP. For certain simulations, we compared RIMM with other receiver‐initiated mesh‐based multicast approaches namely Protocol for Unified Multicasting through multicast Announcement and an ant‐based method called Multicast for Ad Hoc Networks with Swarm Intelligence and found that RIMM has better packet delivery ratio and comparable control overhead.

The Importance of astrocyte‐derived purines in the modulation of sleep
Authors: Blutstein Tamara , Haydon Philip G. 
Published: October 2012

AbstractSleep is an evolutionarily conserved phenomenon that is clearly essential for survival, but we have limited understanding of how and why it is so important. Adenosine triphosphate (ATP)/adenosine signaling has been known to be important in the regulation of sleep and recent evidence suggests a critical role for gliotransmission in the modulation of sleep homeostasis. Herein, we review the regulation of ATP/adenosine in the nervous system and provide evidence of a critical role for astrocyte‐derived adenosine in the regulation of sleep homeostasis and the modulation of synaptic transmission. Further understanding of the role of glial cells in the regulation of sleep may provide new targets for pharmaceutical intervention in the treatment of brain dysfunctions, specifically those that are comorbid with sleep disruptions. © 2012 Wiley Periodicals, Inc

Published: October 2012

AbstractAlcohol is an established carcinogen but not an established risk factor for prostate cancer, despite some recent prospective studies suggesting increased risk among heavy drinkers. The aim of this study was to investigate the role of alcohol on prostate‐specific antigen (PSA) levels and prostate cancer risk. Two thousand four hundred PSA detected prostate cancer cases and 12,700 controls matched on age and general practice were identified through a case‐control study nested in the PSA‐testing phase of a large UK‐based randomized controlled trial for prostate cancer treatment (ProtecT). Linear and multinomial logistic regression models were used to estimate ratios of geometric means (RGMs) of PSA and relative risk ratios (RRRs) of prostate cancer by stage and grade, with 95% confidence intervals (CIs), associated with weekly alcohol intake and drinking patterns. We found evidence of lower PSA (RGM 0.98, 95% CI: 0.98–0.99) and decreased risk of low Gleason‐grade (RRR 0.96; 95%CI 0.93–0.99) but increased risk of high‐grade prostate cancer (RRR 1.04; 95%CI 0.99–1.08; pdifference=0.004) per 10 units/week increase in alcohol consumption, not explained by current BMI, blood pressure, comorbidities, or reverse causation. This is the first large population‐based study to find evidence of lower PSA levels for increasing alcohol consumption, with potential public health implications for the detection of prostate cancer. Our results also support a modestly higher risk of high‐grade disease for heavy drinkers, but require independent replication to establish the nature of the association of alcohol with low‐grade disease, preferably in cohorts with a heterogeneous case‐mix.

Published: October 2012

AbstractMitochondrial dynamics is highly involved in muscle atrophy, the slow twitch muscle as soleus, preferentially affected by hindlimb unloading (HU), was well characterized by mitochondrial dysfunction in biogenesis. However, the fast twitch muscles like tibialis anterior (TA) and gastrocnemius (GAS), which are the most massive parts of the hindlimb muscles, are less elucidated on mitochondrial adaptations responding to HU. To investigate the mitochondrial dynamic responses and the involved molecules mediating atrophy in TA and GAS, we studied a 4‐week HU mouse model. We found GAS was preferentially affected to atrophy by unloading compared with TA. Furthermore, the depressed mitochondrial biogenesis occurred, accounting for mitochondrial loss in GAS by unloading. PGC‐1α, as well as its transcriptional/post‐translational modification regulators, such as p‐CREB, SIRT1, and p‐AMPK, were consistently reduced in response to unloading in GAS. Molecules relevant to autophagy, mitochondrial fusion, and fission, were compromised following unloading both in TA and GAS. These results suggested that TA exhibited resistance to unloading induced muscle atrophy while GAS presented significant mitochondrial loss, which might be due to the mitochondrial biogenesis suppressed by the inactivation of PGC‐1α. However, both in TA and GAS muscles, a similar sedentary mitochondrial dynamics of mitochondrial fusion and fission was induced by unloading though TA exhibited little muscle atrophy. © 2012 IUBMB, IUBMB Life, 64(11): 901–910, 2012

Published: October 2012

AbstractIntegrated gate driver circuit with Oxide TFTs often suffers from the leakage current problem due to the depletion‐mode TFT's characteristic. This paper analyzed the origin of circuit failure and proposed a leakage current cutting technique in which using output feedback to turn off the normally‐on switches. The feedback scheme is designed not only within its own stage but across the neighboring stages. Compared with previous work, it avoids the degradation of the output caused by the feedback TFT, thus providing a more robust solution. The circuit is fabricated employing a‐IGZO TFTs. The experiment result shows that the circuit works successfully with maximum −4.5V threshould voltage.

AbstractFrequency effects on polymer‐stabilized blue‐phase liquid crystals (BPLCs) are investigated. As the electric field frequency increases, Kerr constant decreases and dielectric heating increases. A physical model (extended Cole‐Cole model) is proposed to fit the experimental results. These results are important on high frequency operation of BPLC displays.

AbstractIn this paper we used a rigorous optical model to investigate the viewing angle properties of patterned retarder (PR) stereoscopic 3D liquid crystal display (LCD). By analyzing the simulation and experiment of passive glasses and PR structure, we suggested several new design structures to enlarge the viewing angle at oblique and horizontal direction. Compare to conventional structure and several new structures [1] [2], our new designs had several advanced features, such as simple structure, low cost, easy to realize and of course wide viewing angle.

AbstractCurrently the production volumes of conventional 2D flat panel displays still outpaces those of 3D displays. In order to put glasses‐free 3D displays on an equal footing we developed a cost effective prism based switchable adapter optical module that can enable conventional 2D displays to switch between 2D and glasses‐free 3D mode. Our simulations also show that switchable 2D / multi‐viewer glasses‐free 3D is also possible.

22.4: Investigation of Curtain Mura in TFT‐TN Panels after COG ACF Process
Authors: Wang Sheng‐Ya , Liao Wei‐Hsiang , Yang Kei‐Hsiung 
Published: October 2012

AbstractCurtain Mura is caused by stress‐induced change in optical parameters of the TFT‐TN panel after COG ACF process. We have used simulation to identify the most sensitive optical parameters among cell gap, pretilt and twist angles that could be changed by induced residual stress to cause Curtain Mura. We have also measured optical‐parameter variations in the Curtain Mura and Normal zones on a TFT‐TN panel. We conclude that Curtain Mura occurs mainly due to the stress‐induced change in twist angle of the TFT‐TN panel. We also point out that TN‐cell gap designed at Gooch‐Tarry first‐ minimum is an effective way to reduce the occurrence of Curtain Mura.

Published: October 2012

AbstractIn this work, an in‐cell photosensor was fabricated on a flexible display backplane for infrared sensing utilizations, such as optical touch panel, pen‐writing input function, and so on. The IR responsivity of a hydrogenated amorphous silicon thin film transistor was characterized under near‐infrared illuminations of 850 nm and 940 nm wavelengths. A compact active pixel sensor integrating the photo transistor was embedded into the display cell array. The experimental results demonstrate that a photocurrent to dark current ratio above 103, and an infrared sensitivity of 0.2 V/(s·W·m2) of the in‐cell active pixel sensor were obtained. With the advantages of process compatibility, flexibility and low fabrication cost of scaling‐up, the flexible in‐cell infrared sensor can be a very promising optical detector for all kinds of applications.

30.4: Trilateral Filter for Depth Map Interpolation in 3D Video
Authors: Lim Ilsoon , Wey Hocheon , Lee Jaejoon , Park Dusik 
Published: October 2012

AbstractDepth maps are used in many 3D video applications. Often, depth map is available at a lower resolution compared to the corresponding color images. To match the resolution, depth maps must be scaled up to the color image resolution. In this paper, we present an interpolation method of depth maps. The proposed idea is based on the observation that the depth map is highly correlated to the color image and the big correlation offers the reliable knowledge. For this purpose, we develop a trilateral filter that interpolates the low resolution depth map by the temporary high resolution depth map and the high resolution color image. Accordingly, evaluation using the MPEG 3D videos shows that significant improvement of depth quality and rendered view quality.

Published: October 2012

AbstractWe have developed a new soluble FET material having a highly ordered smectic liquid crystal phase of a phenyl and alkyl‐substituted benzothienobenzothiophene derivative, Ph‐BTBT‐10. This BTBT derivative had high processability for solution processes and highly thermal stability thanks to the solid‐like nature of the highly ordered smectic phase. Polycrystalline thin films of ph‐BTBT‐10 spin‐coated at a liquid crystalline temperature of 110 °C were uniform in macroscale and molecularly flat in microscale, and FETs fabricated with the thin films showed high FET mobility of 5.7 cm2/Vs, kept high mobility of 3 cm2/Vs after the thermal stress for 5 minutes up to 150 °C, and still operated even after thermal stress at 170°C.

AbstractIn this paper we present a new form of inorganic printed electronics (PE) that overcomes many of the problems associated with the act of printing electronics. The technique allows for very high speed, inexpensive production of PE products. To illustrate this approach we will describe a solid state lighting (SSL) device based upon a standard InGaN heteroepitaxy and fabricated as micro LEDs dispersed into an ink binder. We believe that this approach will act as a template for further development of inks and techniques that employ fabricated silicon or III‐V semiconductors.

AbstractA high‐speed intra‐panel interface with an enhanced reduced voltage differential signaling (eRVDS) scheme is implemented in a 0.18‐μm high‐voltage CMOS process for the chip‐on‐glass (COG) TFT‐LCD applications. The proposed interface employs the zero‐adjustable equalizer to enhance the maximum data rate, the early charge sharing scheme to improve the interface data transfer efficiency, and dynamic biasing technique to reduce a power consumption of the output buffers. Measured result demonstrates the maximum data rate of 1.4 Gbps from a 1.8‐V supply voltage with a WQXGA 60‐Hz COG TFT‐LCD prototype panel.
