Authors: Do Dinh‐Thuan , Le Chi‐Bao 
Published: June 2019

SummaryThe time switching‐based relaying (TSR) scheme is considered in energy harvesting protocol to implement with its advantage to nonorthogonal multiple access (NOMA) system. In particular, decode‐and‐forward (DF) mode is proposed to employ in relay to forward signal to serve two far NOMA users. There are two main metrics including outage probability and ergodic rate, which are derived in exact expressions with respect to varying performance under impacts of energy harvesting fractions. To evaluate system performance, outage event and related capacity are illustrated, and we tailor performance gap among two NOMA users and such gap can be controlled by selecting of appropriate power allocation factors assigned for each user to obtain optimal performance. By examining node arrangement, target rates and varying transmit signal to noise ratio (SNR), it can be further achieved performance in several situations of such NOMA. As important result, the considered NOMA system outperforms than the conventional multiple access scheme, and this expected result is confirmed in numerical result and theoretical results. We also explore impacts of transmit power at source, noise power, the other key parameters of energy harvesting scheme to exhibit outage, and ergodic performance. Simulation results are presented to corroborate the proposed methodology.

AbstractThe bidentate N‐cyclohexyl‐2‐(3‐hydroxy‐4‐methoxybenzylidene)hydrazine‐1‐carbothioamide Schiff base ligand (HL) was coordinated to divalent nickel, palladium and platinum ions to form square planar complexes. The nickel and palladium complexes, [NiL2], [PdL2] form square planar complexes with 2:1 ligand to metal ratio. The platinum complex, [PtL(dmso)Cl] formed a square planar complex with 1:1 ligand to metal ratio. Platinum undergoes in situ reaction with DMSO before complexing with the ligand in solution. The cytotoxicity of HL, [NiL2], [PdL2], and [PtL(dmso)Cl] were evaluated against human colon cancer cell line (HCT‐116), human cervical cancer (Hela) cell line, melanoma (B16F10) cells, and human normal endothelial cell lines (Eahy926) by MTT assay. The [NiL2] complex displayed selective cytotoxic effect against the HCT 116 cancer cell line with IC50 of 7.9 ± 0.2 μM. However, HL, [PdL2], and [PtL(dmso)Cl] only exhibited moderate cytotoxic activity with IC50 = 75.9 ± 2.4, 100.0 ± 1.8, and 101.0 ± 3.6 μM, respectively. The potent cytotoxicity of [NiL2] was characterized using Hoechst and Rhodamine assays. The nickel complex, [NiL2], caused remarkable nuclear condensation and reduction in mitochondrial membrane potential. In addition, molecular docking studies confirms that [NiL2] possesses significant binding efficiency with Tyrosine kinase. Altogether, the results revealed that [NiL2] exhibits cytotoxicity against the cancer cells via Tyrosine kinase‐induced proapoptosis pathway. This study demonstrates that the [NiL2] complex could be a promising therapeutic agent against colorectal carcinoma.

AbstractSpatial variability of surface energy and water fluxes at local scales is strongly controlled by soil and micrometeorological conditions. Thus, the accurate estimation of these fluxes from space at high spatial resolution has the potential to improve prediction of the impact of land‐use changes on the local environment. In this study, Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) and Large‐Scale Biosphere‐Atmosphere Experiment in Amazonia (LBA) data were used to examine the partitioning of surface energy and water fluxes over different land‐cover types in one wet year (2004) and one drought year (2005) in eastern Rondonia state, Brazil. The spatial variation of albedo, net radiation (Rn), soil (G) and sensible (H) heat fluxes, evapotranspiration (ET), and evaporative fraction (EF) were primarily related to the lower presence of forest (primary [PF] or secondary [SF]) in the western side of the Ji‐Parana River in comparison with the eastern side, located within the Jaru Biological Reserve protected area. Water limitation in this part of Amazonia tends to affect anthropic (pasture [PA] and agriculture [AG]) ecosystems more than the natural land covers (PF and SF). We found statistically significant differences on the surface fluxes prior to and ~1 year after the deforestation. Rn over forested areas is ~10% greater in comparison with PA and AG. Deforestation and consequent transition to PA or AG increased the total energy (~200–400%) used to heat the soil subsurface and raise air temperatures. These differences in energy partitioning contributed to approximately three times higher ET over forested areas in comparison with nonforested areas. The conversion of PF to AG is likely to have a higher impact in the local climate in this part of Amazonia when compared with the change to PA and SF, respectively. These results illustrate the importance of conserving secondary forest areas in Amazonia.

Published: June 2019

AbstractThis paper proposes dependable multi‐population improved brain storm optimization with differential evolution for optimal operational planning of energy plants. The problem can be formulated as a mixed‐integer nonlinear programming problem and various evolutionary computation techniques such as particle swarm optimization (PSO), differential evolutionary PSO (DEEPSO), multi‐population DEEPSO (MP‐DEEPSO), and brain storm optimization have been applied so far. When optimal operational planning of numbers of energy plants is calculated simultaneously in a data center, a challenge is to generate optimal operational planning as rapidly as possible considering control intervals and numbers of treated plants. One of the solutions for the challenge is speeding up by parallel and distributed computing. It utilizes numbers of processes and countermeasures for various faults of the distributed processes should be considered. Moreover, successive calculation at every control interval is required for keeping customer services. Therefore, sustainable (dependable) calculation keeping appropriate solution quality is required even if some of the calculation results cannot be returned from distributed processes. It is verified that total energy cost by the proposed dependable multi‐population improved brain storm optimization with differential evolution strategy based method is lower than those by the compared methods, and higher quality of solutions can be kept even with high fault probabilities.

Published: June 2019

ABSTRACTConstraining time is of critical importance to evaluating the rates and relative contributions of processes driving landscape change in sedimentary basins. The geomorphic character of the field setting guides the application of geochronologic or instrumental tools to this problem, because the viability of methods can be highly influenced by geomorphic attributes. For example, sediment yield and the linked potential for organic preservation may govern the usefulness of radiocarbon dating. Similarly, the rate of sediment transport from source to sink may determine the maturity and/or light exposure of mineral grains arriving in the delta and thus the feasibility of luminescence dating. Here, we explore the viability and quirks of dating and instrumental methods that have been applied in the Bengal Basin, and review the records that they have yielded. This immense, dynamic, and spatially variable system hosts the world's most inhabited delta. Outlining a framework for successful chronologic applications is thus of value to managing water and sediment resources for humans, here and in other populated deltas worldwide. Our review covers radiocarbon dating, luminescence dating, archaeological records and historical maps, short‐lived radioisotopes, horizon markers and rod surface elevation tables, geodetic observations, and surface instrumentation. Combined, these tools can be used to reconstruct the history of the Bengal Basin from Late Pleistocene to present day. The growing variety and scope of Bengal Basin geochronology and instrumentation opens doors for research integrating basin processes across spatial and temporal scales. © 2019 The Authors.

AbstractNa3TiV(PO4)3/C nanoparticles are synthesized by a simple ball‐milling method and studied for sodium‐ion symmetrical and full batteries. Symmetrical battery assembled with Na3TiV(PO4)3/C nanoparticles shows good structural stability and acceptable capacity. Sodium‐ion full battery exhibits an initial capacity of 200 mA h g−1 and maintains 90 mA h g−1 after 100 cycles when the presodiated commercial hard carbon is chosen as the anode. Moreover, the wide sources of raw materials and low environmental pollution mean that Na3TiV(PO4)3/C nanoparticles may have certain industrial prospects.

AbstractBackgroundThere is a lack of consensus regarding the management of T4a larynx cancer. We evaluated the outcomes of organ preservation and laryngectomy for T4a laryngeal cancer.MethodsRetrospective analysis of patients with T4a larynx cancer at BC Cancer from 1984 to 2014 was performed. Outcomes in patients treated with surgery alone (Sx) (n = 47), surgery with adjuvant radiotherapy (Sx/RT) (n = 94), radiation alone (RT) (n = 152), and radiation with concurrent chemoradiotherapy (chemoRT) (n = 36) were compared.ResultsThe 5‐year overall survival (OS) was 40% for chemoRT, 34% for RT, 23% for Sx, and 45% for Sx/RT. On multivariate analysis (MVA), Sx/RT (hazard ratio [HR], 0.66; 95% confidence interval [CI], 0.48‐0.91) and chemoRT (HR, 0.44; 95% CI, 0.26‐0.72) were associated with better OS than RT alone (P = .001). Sx had similar OS compared to RT (HR, 1.17; 95% CI, 0.82‐1.68).ConclusionsChemoRT and Sx/RT were associated with better OS compared to single modality treatment. ChemoRT may be considered as an option for T4a larynx cancer.

AbstractIssue addressedSince 1986, injury prevention and control has been classified as a National Health Priority. However, no reviews into the injury prevention workforce have been conducted in Australia since 2011 and to date; none has focused specifically on the injury prevention and safety promotion sector in Western Australia (WA). This research sought to review the scope of the injury prevention and safety promotion workforce in WA to gain a greater understanding of sector characteristics, work and needs.MethodsAn online, cross‐sectional survey was conducted between mid‐January and mid‐March 2018. Participants were required to be: (a) based in WA or have a program running within WA; and (b) working in injury prevention and safety promotion relating to programs, policy or legislation development, implementation and/or evaluation within intentional (eg interpersonal violence, suicide and self‐harm) or unintentional injuries (eg transport, poisoning, falls, drowning, burns) or farm, child and community, occupational health and safety, sport and recreation and trauma.ResultsThe research found that participants were predominantly female (82%), aged 40 years or older (66.1%) and were employed full time (55.6%). The majority of participants worked in falls prevention (38.5%), alcohol and other drugs (38.0%), injury in general (31.8%) and community safety (30.7%).ConclusionsFindings demonstrate significant heterogeneity with a core workforce supported by a range of non‐core and indirect actors. Identifying characteristics and needs of the workforce supports coordinated capacity building to implement effective injury prevention and safety promotion initiatives. With this being the first review of the workforce in WA, this article highlights the need to more regularly audit the sector to determine its breadth and composition.So what?In the light of the recent announcement by the Commonwealth for a new national Injury Prevention Strategy, this study provides timely insights into the injury prevention and safety promotion sector in WA.

AbstractThe study on the hydraulic properties of coastal aquifers has significant implications both in hydrological sciences and environmental engineering. Although many analytical solutions are available, most of them are based on the same basic assumption that assumes aquifers extend landward semi‐infinitely, which does not necessarily reflect the reality. In this study, the general solutions for a leaky confined coastal aquifer have been developed that consider both finitely landward constant‐head and no‐flow boundaries. The newly developed solutions were then used to examine theoretically the joint effects of leakage and aquifer length on hydraulic head fluctuations within the leaky confined aquifer, and the validity of using the simplified solution, which assumes the aquifer is semi‐infinite. The results illustrated that the use of the simplified solution may cause significant errors, depending on joint effects of leakage and aquifer length. A dimensionless characteristic parameter was then proposed as an index for judging the applicability of the simplified solution. In addition, practical application of the general solution for the constant‐head inland boundary was used to characterize the hydraulic properties of a leaky confined aquifer using the data collected from a field site at the Seine River estuary, France, and the versatility of the general solution was further justified.

Published: June 2019

AbstractVisual stimulus decoding is an increasingly important challenge in neuroscience. The goal is to classify the activity patterns from the human brain; during the sighting of visual objects. One of the crucial problems in the brain decoder is the selecting informative voxels. We propose a meta‐heuristic voxel selection framework for brain decoding. It is composed of four phases: preprocessing of fMRI data; filtering insignificant voxels; postprocessing; and meta‐heuristics selection. The main contribution is benefiting a meta‐heuristics search algorithm to guide a wrapper voxel selection. The main criterion to nominate a voxel is based on its mutual information with the provided stimulus label. The results show impressive accuracy rates which are 90.66 ± 3.66 and 91.61 ± 8.24 for DS105 and DS107, respectively. This outperforms the most of existing brain decoders in similar validation conditions. The experimental results are very encouraging which can be successfully used in the brain‐computer interface.

AbstractObjectiveTo assess the quality of medication optimization for transient ischemic attack (TIA) and minor stroke patients across the Veterans Health Administration (VHA), and to identify characteristics predicting medication optimization for hypertension, hyperlipidemia, and diabetes. The scope of this study focuses on these three medication‐related conditions and defines optimization as medication changes or additions made within a guideline‐defined timeframe.MethodsWe constructed a retrospective cohort including all patients discharged with a TIA or minor stroke (index event) in any VHA Emergency Department (ED) or inpatient setting during fiscal year 2011. Inpatient and outpatient medical/pharmacy data were collected from a variety of electronic health sources for 1 year prior to and up to 90 days after discharge. Medication optimization for hypertension, hyperlipidemia, and diabetes was defined using relevant VHA and American Heart Association/American Stroke Association guidelines. For each of the three medication‐based outcomes, multivariable logistic regression models examined demographic, past medical history, and other clinical variables to identify predictors of optimization.ResultsAmong 8427 patients, 33.7% (n = 2837) were eligible for medication optimization for hypertension, 55.2% (n = 4655) for hyperlipidemia, and 7.2% (n = 606) for diabetes. Guideline‐concordant medication optimization occurred for 28% of eligible patients with hypertension, 28% of patients with hyperlipidemia, and 34% of patients with diabetes. Factors that were associated with medication optimization included younger age, inpatient stay (vs discharge from the ED), greater baseline disease severity (higher blood pressure, low‐density lipoprotein [LDL] cholesterol, or hemoglobin A1c [glycated hemoglobin]), and primary care follow‐up within 30 days after the index event.ConclusionOne‐third or fewer eligible patients with TIA or minor stroke had their medications optimized in a timely manner in concordance with evidence‐based guidelines. Interventions to improve timely medication optimization are needed to reduce the risk of recurrent vascular events in this high‐risk population.
Inverse spatially‐offset Raman spectroscopy using optical fibers: An axicon lens‐free approach

Published: June 2019

AbstractInverse spatially offset Raman spectroscopy (I‐SORS) seeks to interrogate deep inside a Raman‐active, layered, diffusely scattering sample. It makes a collimated laser beam incident onto the sample surface in the form of concentric illumination rings (of varying radii) from whose center the back‐scattered Raman signal is collected for detection. Since formation of illumination rings of different sizes requires an axicon to be moved along the axis of the collimated laser beam and axicons below a certain minimum size (~1 inch) are not readily available, this classical configuration incorporating an axicon cannot be used for designing a compact I‐SORS probe of narrower diameter. We report a novel scheme of implementing I‐SORS which overcomes this limitation by implementing ring illumination and point collection using two multi‐mode optical fibers. An important advantage of the proposed scheme is that unlike the previously reported inverse SORS configurations, it does not require physical movement of any of the optical components for generating spatial offsets needed for probing sub‐surface depths. Another advantage is its fiber‐optic configuration which is ideally suited for designing a compact and pencil‐sized I‐SORS probe, often desired in many practical situations for carrying out depth‐sensitive Raman measurements in situ from a layered turbid sample.
XIST/miR‐376c‐5p/OPN axis modulates the influence of proinflammatory M1 macrophages on osteoarthritis chondrocyte apoptosis

Published: June 2019

AbstractThe inflammatory microenvironment in the joints is one of the critical issues during osteoarthritis (OA) and also the main factor that may aggravate symptoms. Under inflammatory microenvironment, M1 macrophages are activated and produce large numbers of proinflammatory mediators, leading to the production of degradative enzymes, the disturbance of chondrocyte apoptosis and cartilage catabolic processes, and finally the deterioration of OA. In the present study, we reveal that the overexpression of osteopontin (OPN), a cytokine, and a matrix protein involved in arthritis and chondrocyte apoptosis in OA, could exacerbate the inflammatory microenvironment in OA via promoting the production of proinflammation cytokines and the levels of degradative enzymes in M1 macrophages, therefore, enhancing the cytotoxicity of M1 macrophage on chondrocytes. XIST expression significantly increases in OA tissue specimens. XIST serves as a competing endogenous RNA for miR‐376c‐5p to compete with OPN for miR‐376c‐5p binding, thus counteracting miR‐376c‐5p‐mediated OPN suppression. XIST knockdown could improve the inflammatory microenvironment in OA via acting on M1 macrophages, subsequently affecting the apoptosis of cocultured chondrocytes. miR‐376c‐5p inhibition exerts an opposing effect on M1 macrophages and cocultured chondrocytes, as well as significantly reverses the effect of XIST knockdown. As a further confirmation, XIST and OPN mRNA expression significantly increased in OA tissues and was positively correlated in tissue samples. In summary, we provide a novel mechanism of macrophages and the inflammatory microenvironment affecting chondrocyte apoptosis. XIST and OPN might be potential targets for OA treatment, which needs further in vivo experimental confirmation.
