Effects of Cognitive Training and Exergaming in Pediatric Cancer Survivors—A Randomized Clinical Trial

Supplemental digital content is available in the text. ABSTRACT Purpose Although most pediatric cancer patients survive, those who undergo anticancer treatments like chemotherapy and/or radiotherapy are at a high risk for late effects, such as cognitive deficits. To counteract these deficits, feasible and effective interventions are needed. The aim of this study was to compare the effects of working memory training, exergaming, and a wait-list control condition on cognitive functions in pediatric cancer survivors. Methods In a parallel-group randomized trial, 69 pediatric cancer survivors aged 7–16 yr (mean = 11.35, SD = 3.53) were randomly assigned to 8-wk working memory training, exergaming, or a wait-list control group. Each training course consisted of three 45-min training sessions per week. The primary outcome comprised the core executive functions (visual working memory, inhibition, switching), and the secondary outcomes included other cognitive domains (intelligence, planning, memory, attention, processing speed), motor abilities, and parent rating on their children’s executive functions. Assessments were conducted both before and immediately after the interventions, and at 3-month follow-up. Results Linear mixed models revealed that participants in the working memory training group showed a linear improvement in visual working memory after training and at follow-up compared with the control group. No other intervention effects of either type of training could be detected. Conclusion This study presents evidence that working memory training improves visual working memory in pediatric cancer survivors. Results show that near-transfer, but no far-transfer effects can be expected from working memory training. Multiple-component interventions tailored to fit the individual’s cognitive profile are needed to best support cognitive development after cancer and its treatment.
‘Finding the image’: using photos to give voice to teacher educator professional learning

ABSTRACT Our purpose was to explore the role of photocue reflection in the professional learning of physical education teacher educators. Five physical education teacher educators participated in a six-month professional learning experience focused on communication. Individual diaries including both photos and writing prompts, photocue reflective diaries, were used as both a learning tool and data source within a self-study of teacher education practices methodological frame. Two themes represented the use of photocue reflection: the multidimensional nature of the professional development experience and the use of photocue reflection to enhance reflective processes by supporting reflection on reflection-in-action. Photocue reflection supported identification and analysis of meaningful events related to communication. The processes helped participants to appreciate the significance of communication, clarifying understandings, and making connections to their teacher education practices. Insight is shared on the merits of photocue reflection in scaffolding professional learning experiences and in combining both a learner and teacher role within professional development activities.
Sensitivity of different methods for the detection of Ralstonia solanacearum in potato tuber extracts

The sensitivities of various methods for the detection of Ralstonia solanacearum following dilution in healthy potato tuber tissue macerate were compared. Estimated pathogen populations in undiluted macerates, from samples of 200 heel-end vascular cores each containing a single diseased and 199 healthy tubers, ranged from 1.2 × 106–7.4 × 107 colony-forming units per ml. Following concentration by high-speed centrifugation and resuspension in phosphate buffer, the pathogen was detected by all methods studied, including culture on semi-selective media, enzyme-linked immunosorbent assay (ELISA), indirect immunofluorescent-antibody staining (IFAS) of fixed cells, immunofluorescent colony staining (IFCS), detection of specific DNA sequences following amplification by the polymerase chain reaction (PCR) and bioassay in tomato seedlings. Both ELISA and PCR methods were improved by pre-enrichment of samples in semi-selective broth prior to testing. A nested PCR method was evaluated which could detect fewer than 10 cells per ml in the potato extracts. Of the other methods only dilution plating on semi-selective medium and tomato bioassay could detect fewer than 104 cells per ml. In order to combine ease and speed of use with sensitive detection, it was recommended that a series of methods be used for routine screening of potato tuber stocks for infection by R. solanacearum.
Effect of Aqueous Extract of Citrullus lanatus (Water Melon) Seeds on Alloxan Induced - Diabetic Wistar Rats

This study was designed to evaluate the effect of aqueous extract of Citrullus lanatus (water melon) seeds on alloxan induced-diabetic wistar rats. The Wistar rats were grouped into 11 of 3 rats in each. Groups 2-11 received single dose of 120 mg/kg b.wt of alloxan monohydrate intraperitoneally. Groups 4 and 5 orally received a dose of 100 mg/kg b.wt of metformin for 7 and 21 days respectively. Groups 6, 8 and 10 orally received 200 mg/kg b.wt, 400 mg/kg b.wt, and 600 mg/kg b.wt. of the extract respectively for 7 days while groups 7, 9 and 11 orally received 200 mg/kg b.wt. , 400 mg/kg b.wt and 600 mg/kg b.wt of the extract respectively for 21 days. Blood samples were collected 24 hours after 7 and 21 days of treatment and selected biochemical parameters were determined; glucose determination, pancreatic αamylase activities and lipid profile, while histopathology examination of the pancreas was also examined. Qualitative phytochemical result showed the presence of flavonoids, alkaloids, saponin, tannin, oxalate and phytate. Flavonoids (176.87 ug/g) were most abundant and phytate was the least occurring anti nutrient (6.75±0.06). Citrullus lanatus seeds extract significantly (p≤0.05) decreased the plasma glucose levels, Original Research Article Ogbeifun et al.; AJRB, 6(2): 30-44, 2020; Article no.AJRB. 55653 31 pancreatic α-amylase activities, total cholesterol, triglycerides and lipoproteins while there was a significant (p≤0.05) increase in high density lipoproprotein levels on 7 and 21 days in all the extract treated groups. The histopathological examination of the pancreas showed regeneration of pancreatic cells in all the extract treated groups. The aqueous extract of Citrullus lanatus (water melon) seeds is rich in phytochemicals with antioxidant properties hence could serve as novel herbal antidiabetic agent.
Compiler-Assisted Data Streaming for Regular Code Structures

The performance of modern processors is often limited by execution stalls resulting from long memory access latencies. Compile-time optimizations, deep cache hierarchies and prefetching mechanisms already provide significant performance gains, by performing memory accesses in parallel with computation. However, they are reaching a throughput improvement limit. Hence, new solutions that effectively exploit the memory access patterns to improve processing throughput are required. To achieve this objective, a new compiler-assisted data streaming method is proposed. It leverages static analysis and code transformations with an on-chip data streaming support as a viable alternative to prefetching mechanisms for regular code structures. Static analysis is used to identify and encode memory accesses with a dedicated representation. Then, a code transformation algorithm detaches data indexation and address calculation from computation, allowing for a significant code reduction. An on-chip data stream controller, attached to the L1 data cache, is used to autonomously generate memory accesses from the pattern representation and reorganize the data transfers in streams, with the aid of stream buffers. When compared with state-of-the-art prefetchers, the proposed solution provides up to 26 percent of code reduction, an IPC improvement of 2.4x, and an average performance improvement of 40 percent.
Effect of alloy elements on the weld of galvanised sheet studied by first-principles

To solve the problem of zinc to the weld quality of galvanised sheet, alloy elements (Cu, Nb, Y) have been added to combine with zinc to form stable compounds during welding. The structure and properties of CuZn, NbZn3 and YZn compounds were calculated by first-principles. The calculation results show that all three elements form a stable alloy with Zn. Among the alloys formed, CuZn has the best mechanical properties. MIG welding experiments of galvanised sheet were conducted to verify the effects of Cu addition on the weld seam formation. The experimental results show that the addition of Cu powder has little influence on the macro-morphology of the weld. In the centre of the weld, ferrite structure is refined and micro-hardness is improved.
Assemblages of Harpacticoida (Crustacea: Copepoda) from the Ryukyu and Kuril Trenches, north-west Pacific Ocean

To examine the specific features of trench communities, spatial changes in the assemblages of harpacticoids were investigated at the family level around the Ryukyu Trench (the Ryukyu region) and Kuril Trench (the Kuril region). In the Ryukyu region, there were high average dissimilarities in the harpacticoid assemblages among the trench, trench slope and abyssal plain, indicating that the assemblage structures differ substantially between these topographic settings at the family level. Conversely, in the Kuril region, the average dissimilarities in harpacticoid assemblages between the trench and the trench slope and between the trench and the abyssal plain were lower than that between the slope and the abyssal plain. This result suggests that the hadal assemblage is a transition zone between the slope and the abyssal plain in this region. In addition, the analyses indicate that the composition of harpacticoid assemblages is influenced by the quantity of organic matter in the Ryukyu region, while sediment properties play a key role in the Kuril region. Comparisons of the assemblages between the two regions, however, revealed that the average dissimilarities between the trenches and between the abyssal plains were higher than that between the adjacent slopes. This result suggests that interchange among regions is difficult for deep-sea benthic animals, including harpacticoid copepods, likely due to the presence of physical barriers around trenches.
Joint Precoding Optimization for Secure SWIPT in UAV-Aided NOMA Networks

Combination of unmanned aerial vehicle (UAV) and non-orthogonal multiple access (NOMA) is deemed as an promising solution to achieving massive connectivity in future wireless networks. In this paper, a UAV-aided NOMA scheme is proposed to achieve simultaneous wireless information and power transfer (SWIPT) and guarantee the secure transmission for ground passive receivers (PRs), in which the nonlinear energy harvesting model is applied. Each time frame is divided into two phases. In the first phase, the received power at each PR is maximized to achieve rapid charging. In the second phase, SWIPT is performed via NOMA with the remaining energy at each PR, and artificial jamming is generated at UAV together with the NOMA information to guarantee the security. The throughput of PRs is maximized, with the highest received jamming power cancelled at each PR via successive interference cancellation (SIC). This disrupts the eavesdropping effectively by jamming without affecting the legitimate transmission. Due to the non-convexity of these two optimization problems, we first convert them to convex ones and then propose iterative algorithms to solve them. Simulation results are presented to show the effectiveness of the proposed scheme.
Effect of Type and Permeability Behaviour of Packaging Material on the Quality Characteristics of Dried Carrot Roundels during Storage

Carrot (Daucus carota L) is a carotenoids rich vegetable which is mainly consumed raw, converted to various products and cooked vegetable dishes. Present studies were carried out to study the changes observed in quality characteristics of dried carrot roundels during storage. Steam blanching and KMS dipping of carrot roundels followed by mechanical cabinet drying was found to be the best pretreatment for drying of carrot roundels as discussed earlier. These dried carrot roundels were further packed and stored under refrigerated (4-7°C) and ambient (11.6-26.2°C) storage conditions for 12 months. The dried carrot roundels packed in aluminium laminated pouches and stored under refrigerated conditions showed minimum increase in physico-chemical characteristics like moisture content (11.03%), water activity (0.310), pH (6.04), reducing sugars (21.00%), total sugars (35.36%) and retained highest amounts of titratable acidity (0.73%), carotenoids (29.40mg/100g), total phenols (87.50mg/100g), crude fibres (4.16%), rehydration ratio (7.81), antioxidant activity (52.68%) and SO2 content (174.75 ppm), respectively. The sensory characteristics scores like colour (8.05), texture (7.48), taste (6.88) and overall acceptability (7.54), respectively were also retained highest in the aluminium laminated pouch under refrigerated storage condition.
Evidence of Smaller 1/F Noise in AlScN-Based Oscillators Compared to AlN-Based Oscillators

In this paper we investigate the direct effect of resonator quality factor (<inline-formula> <tex-math notation="LaTeX">$Q$ </tex-math></inline-formula>) on the oscillator phase noise. We use 2-port contour mode resonators (CMRs), fabricated both with aluminum nitride (AlN) and aluminum scandium nitride (AlScN), as the frequency-determining element in the oscillator circuit. Over 70 oscillator configurations are tested using resonators with different <inline-formula> <tex-math notation="LaTeX">$Q$ </tex-math></inline-formula> and with different piezoelectric layer. The testing of so many devices is possible because, in our setup, interfacing the circuit to the resonator is streamlined using RF probes. Our results show that higher resonator <inline-formula> <tex-math notation="LaTeX">$Q$ </tex-math></inline-formula> yields better frequency stability of the oscillator, for both AlN and AlScN CMRs. Interestingly, the comparison between AlN-based oscillators and AlScN-based oscillators with equal <inline-formula> <tex-math notation="LaTeX">$Q$ </tex-math></inline-formula> shows that AlScN-based oscillators’ Phase Noise is up 10 dBc/Hz better than the AlN oscillator at 1 kHz offset frequency, suggesting different intrinsic resonator flicker noise of the two piezoelectric layers.

Transversal tracheid dimension in thinned black spruce and Jack pine stands in the boreal forest

Abstract Commercial thinning has recently been applied in the boreal forest of Quebec (Canada) to increase the volume growth of the residual trees. We aimed to discover if the growth response influences the transversal tracheid dimension of thinned black spruce (Picea mariana (Mill.) B.S.P.) and Jack pine (Pinus banksiana Lamb.) stands at 0.2 m stem height. All 20 studied stands have shown a significant growth response after the treatment (p<0.0001), especially trees with the lowest radial growth before thinning in comparison with the stand mean. Growing conditions met by suppressed trees before thinning might favour them in the competition for light, water and biomass production after the treatment. Trees with a positive growth response did not significantly modify their measured transversal tracheid dimension except for trees which increased twofold their ring-width after thinning. In this case, lumen area and radial cell diameter extended significantly. However individuals with a growth decrease after thinning registered significantly lower values in their ring width, earlywood and latewood cell numbers (p<0.0001) in both species.
On the distance between A and B in molecular configuration space

ABSTRACT In this brief review, we discuss the question of calculating the distance between different molecular configurations. We focus on the theoretical basis of different existing methods for this problem, including ones which are more physics-driven and ones which are more data-driven. We explain the key ideas behind these methods, and conclude with what we see as the central challenges. We hope this review will be helpful to someone aiming to understand these methods, many of which are new and have not been compared and reviewed together. We also hope it will help develop new methods that address the challenges we identify and others.
Precipitation Trends Over Mainland China From 1961–2016 After Removal of Measurement Biases

Following the removal of measurement biases from daily observed gauge records for the period 1961–2016 at 2,250 national stations over mainland China, the precipitation trends and causes were analyzed. Measured annual precipitation trends have been overestimated to varying degrees in most regions, with the exceptions of Northwest China and northern Tibet. On average, the annual precipitation trend over mainland China decreased from 3.98 to 2.04 mm/10 yr after bias adjustment. The dramatically precipitation‐increasing (wetting) zones in Northeast China and the lower reaches of the Yangtze River were found to be disappearing at a faster rate than what we observed. Meanwhile, the extent of markedly precipitation‐decreasing (drying) zones in the Yellow River Basin shrank more slowly than what was indicated by measured records. Adjusted annual light rain amounts exhibited a weaker increasing trend over mainland China; conversely, adjusted annual rainstorm amounts displayed stronger increasing trends than reported previously. The changes of trace precipitation days, precipitation days, mean wind speed on precipitation days, and observed precipitation amount comprehensively affected the trends of bias‐removed precipitation. The declines in measured wind speed and precipitation amount resulted in accelerated reductions in adjusted precipitation over Southwest and North China. In Southeast China, the increasing trend of bias‐adjusted precipitation was smaller than that indicated by original data due to the reduction in mean wind speed when precipitation occurred. In Northwest China and northern Tibet, however, the increases in measured precipitation amount and precipitation days mutually led to larger increasing trends in the adjusted data.
Scientific Communities Striving for a Common Cause: Innovations in Carbon Cycle Science

Where does the carbon released by burning fossil fuels go? Currently, ocean and land systems remove about half of the CO2 emitted by human activities; the remainder stays in the atmosphere. These removal processes are sensitive to feedbacks in the energy, carbon, and water cycles that will change in the future. Observing how much carbon is taken up on land through photosynthesis is complicated because carbon is simultaneously respired by plants, animals, and microbes. Global observations from satellites and air samples suggest that natural ecosystems take up about as much CO2 as they emit. To match the data, our land models generate imaginary Earths where carbon uptake and respiration are roughly balanced, but the absolute quantities of carbon being exchanged vary widely. Getting the magnitude of the flux is essential to make sure our models are capturing the right pattern for the right reasons. Combining two cutting-edge tools, carbonyl sulfide (OCS) and solar-induced fluorescence (SIF), will help develop an independent answer of how much carbon is being taken up by global ecosystems. Photosynthesis requires CO2, light, and water. OCS provides a spatially and temporally integrated picture of the “front door” of photosynthesis, proportional to CO2 uptake and water loss through plant stomata. SIF provides a high-resolution snapshot of the “side door,” scaling with the light captured by leaves. These two independent pieces of information help us understand plant water and carbon exchange. A coordinated effort to generate SIF and OCS data through satellite, airborne, and ground observations will improve our process-based models to predict how these cycles will change in the future.
THE INFLUENCE OF SELF-EFFICACY, TASK VALUE, AND GOAL ORIENTATION ON HELP-SEEKING AND ACADEMIC PERFORMANCE

Purpose of the study: This study aimed to investigate the influence of task-value, goal orientation and self-efficacy on the help-seeking of the students, and thereafter on the academic performance. Methodology: To carry out research findings, a quantitative survey was applied by employing a self-regulated online learning questionnaire (SOL-Q), and a Motivated Strategies for Learning Questionnaire (MSLQ). A total of 317 university Arabic learners participated in the present study. Analysis of data used SPSS version 22 software. Both descriptive and inferential statistics were used to analyse the data and to examine the relationship among learners’ help-seeking, motivation, and learners’ GPA. Main Findings: The results of the present study provide support to the motivational beliefs (SE and TV) predict help-seeking, and students who endorsed high self-efficacy are more likely seeking help from others, and achieve high performance as well. Applications of this study: This study will enable faculty management, instructors, and students to better understand the essential role of help-seeking and motivational factors in Arabic language learning. Novelty/Originality of this study: The case of Self-Efficacy, Task Value, Goal Orientation, Help-Seeking, and Academic Performance were widely explained by the number of researchers. But there is no recent publication that has explained the influence of Self-Efficacy, Task Value, and Goal Orientation on Help-Seeking within the Arabic learning context.
Cephalaria duzceensis (Dipsacaceae), a new species from the western Black Sea region, Turkey

A new species, Cephalaria duzceensis N. Aksoy & R. S. Gokturk (Dipsacaceae) from western Black Sea region of Turkey is described. It is illustrated in line drawings and the morphology of the new species is compared with Cephalaria speciosa. Molecular and morphological methods were used to separate the two species. Both species were first identified morphologically and then studied by randomly amplified polymorphic DNA (RAPD) markers. Genetic similarities were calculated based on the RAPD data and used to construct a UPGMA dendrogram. According to the result, two main clusters were observed using the character differences. It is concluded that C. duzceensis sp. nov. is different from C. speciosa.
Too Red for Crowdfunding: The Legitimation and Adoption of Crowdfunding Across Political Cultures

Institutional change is typically studied at the organizational field level; we leverage political culture to examine how the context in which these fields are embedded influence processes of institutional change within such fields. Specifically, we look at the effect of conservative political culture on legitimation and adoption of crowdfunding in the United States. We find that crowdfunding is less popular and more slowly legitimated in conservative regions. However, we also find that crowdfunding’s legitimacy is more important in these regions and that once a legitimacy threshold is reached, the adoption of crowdfunding in conservative regions surpasses that in liberal regions.
POTASSIUM NUTRITION IN THE OIL PALM: A MOLECULAR PERSPECTIVE

Potassium (K + ) is a major nutrient essential for plant growth and development. Acquisition of this vital element and maintenance of K + homeostasis are complex processes, facilitated by an array of membrane transporters including carriers and channels. Key mediators of K + uptake are the K + Transporters (KT) /K + Uptake Permease (KUP)/ High Affinity K + (HAK) family of transporters. The oil palm (Elaeis guineensis) , is an agriculturally and economically important crop, but the molecular mechanisms of nutrient acquisition in this plant are poorly understood. Here we report the first molecular characterisation of potassium transporters from KT/KUP/HAK superfamily in the oil palm, named EgKUP3, EgKUP8 and EgKUP11.
