Climate Model Projections of 21st Century Global Warming Constrained Using the Observed Warming Trend

The Coupled Model Intercomparison Project Phase 6 (CMIP6) archive includes larger ensembles, longer historical simulations, and models with a broader range of climate sensitivity than CMIP5. These features favor the application of observationally constrained climate projections. The 1970–2014 trend in global mean temperature is well‐correlated with projected future warming across the CMIP6 multimodel ensemble. We first evaluate an approach that weights simulations based on the realism and degree of independence of their 1970–2014 trends, by treating each historical simulation in turn as pseudo‐observations, and using the other models and weighting method to predict 21st century warming in the model concerned. The method performs well based on correlation and probabilistic measures. Applying the method using the observed 1970–2014 warming trend results in only small changes in the mean and lower bound of CMIP6 projected warming but substantially reduces the upper bound of projected early‐, mid‐ and late‐21st century warming under all SSP scenarios.
An electrophysiological study on the effects of pH on olfaction in mature male Atlantic salmon (Salmo salar) parr

The olfactory responses of mature male Atlantic salmon (Salmo salar L.) parr to known odorants were studied after exposure of the olfactory epithelia to water of varying pH. Electrophysiological recordings from the olfactory epithelia indicated that the responses of fish to both testosterone and urine from ovulated female Atlantic salmon were significantly reduced at pH 5·5 and 4·5 and abolished at pH 3·5. Concentration response studies indicated that at pH 5·5 and 6·5 significantly higher concentrations of testosterone and urine were required to produce the same amplitude responses as controls. Both testosterone and urine have previously been shown to be important chemical cues eliciting behavioural and physiological responses in Atlantic salmon. The results are therefore discussed in relation to the possible sublethal effects of acidification on reproduction and behaviour of Atlantic salmon and the effects on salmonid stocks.
Test-Retest and Intrarater Reliability of Assessing Tibial Rotation Range of Motion by Two Devices

Rotational motion at the tibia is important for proper lower extremity function, however, normative values vary, and the motion is seldom assessed. Clinicians are increasingly using smartphones for assessing range of motion. The purpose of the study was to assess the reliability of the embedded iPhone 6 compass app and universal goniometer for measuring tibial rotation range of motion. Secondarily, the purpose was to compare readings for the devices. Both devices demonstrated excellent reliability despite systematic bias between the two devices. Assessing tibial rotation with a goniometer results in greater values of motion when compared to using the smartphone compass app. Some of the differences in normative values may be the device or measurement technique utilized. These results show tibial rotation can be reliably assessed with either a smartphone or goniometer, however, the deviations between the two devices may require a scaling factor to be developed for between-instrument comparisons.
Qualitative Study on the Perception of Community Food-accessibility Environment among Urban Older Adults

Objectives: This study explored the community food environmental factors affecting food purchasing using a qualitative research methodology for the elderly as well as the various food environments under their socioeconomic diversity. Methods: For the qualitative data collection, this study interviewed 20 elderly people aged 65 years or more, who participated in a public health program or lunch services operated by the senior welfare center in Seoul. Five dimensions, such as availability, physical accessibility, affordability, acceptability, and accommodation suggested in previous studies, were used to identify the community food environmental factors. Results: The elderly participants showed overall similarities to the concepts derived from existing studies on the five dimensions of food accessibility environment. In addition, other important food accessibility environmental factors that were not present in previous studies, such as acceptability for a product of domestic origin, delivery service to home, and small-packaged food sales, were derived. On the other hand, the concept of some subjects differed depending on the household income and specifically for the physical accessibility concept. This showed that the close distance factor from a grocery store at home might not apply to older adults in low-income households in Korea. Conclusions: This study found that five dimensions of the food environment suggested by previous studies could also be applied to vulnerable older adults in Korea. On the other hand, the socioeconomic characteristics of individuals and households would affect the perspectives of their local food environments differently. The findings of this study could help in the development of tools for evaluating the community food environment.
Cancer Patient Perspectives on Sharing of Medical Records and Mobile Device Data for Research Purposes

Sharing data is critical to advancing science, improving health, and creating advances in the delivery of health care services. The value of sharing data for cancer research purposes is well established, and there are multiple initiatives under way that address this need. However, there has been less focus on cancer patient perspectives regarding the sharing of their health information for research purposes. This study examined cancer patient perspectives on the sharing of de-identified health data for research purposes including both data from medical records and mobile applications. This cross-sectional study used survey methodology to collect data from cancer patients/survivors (N = 677). Overall, we found that participants were largely willing (71%) to share de-identified medical data and were most motivated (88%) by a desire to help other cancer patients. Patients were less likely to be comfortable sharing mobile application data (34%). It is vital that we understand patient perspectives on data sharing and work with them as partners, valuing their unique contributions, and attending to their preferences.
Characterizations of Biomasses for Subsequent Thermochemical Conversion: A Comparative Study of Pine Sawdust and Acacia Tortilis

The bioenergy production potential from biomasses is dependent on their characteristics. This study characterized pine sawdust samples from Zimbabwe and acacia tortilis samples from Botswana using conventional and spectrometry techniques. The ultimate analysis results for pine were 45.76% carbon (C), 5.54% hydrogen (H), 0.039% nitrogen (N), 0% sulphur (S) and 48.66% oxygen (O) and, for acacia, were 41.47% C, 5.15% H, 1.23% N, 0% S and 52.15% O. Due to the low N and S in the biomasses, they promise to provide cleaner energy than fossil-based sources. Proximate analysis results, on a dry basis, for acacia were 3.90% ash, 15.59% fixed carbon and 76.51% volatiles matter and 0.83%, 20% and 79.16%, respectively, for pine. A calorific value of 17.57 MJ/kg was obtained for pine, compared with 17.27 MJ/kg for acacia, suggesting they are good thermochemical feedstocks. Acacia’s bulk energy density is five times that of pine, making it excellent for compressed wood applications. Though the ash content in acacia was much higher than in pine, it fell below the fouling and slagging limit of 6%. In pyrolysis, however, high ash contents lead to reduced yields or the quality of bio-oil through catalytic reactions. Fourier transform infrared spectrometry indicated the presence of multiple functional groups, as expected for a biomass and its derivatives.
Establishment of an early selection method (criteria) for breeding in cowpea (Vigna unguiculata)

Populations with high genetic variability are targeted by breeders as they create opportunity for selection and genetic improvement. To achieve this, multiple populations are created, but resources are often scarce. This calls for identification of populations with the desired traits at early generation. The study was carried out at MUARIK in seasons 2017A and 2017B on 135 F2 and 40 F3 cowpea populations respectively together with 25 parental lines aimed at: Determining best performing populations for yield, resistance to scab, virus and flower thrip based on usefulness criterion and selection index methods. Usefulness criterion computed for yield identified NE 36 x 2392 as the best population. Usefulness criterion computed for yield and its components identified NE 5 x Sanzi as the best population. WC 48A x 2392 was identified as the best population using selection index values that included resistance to virus, thrips, scab, yield and its component and when only yield and its components were fitted in the model. Variability and high yield performance was maintained in the forty best populations identified and therefore amendable for future improvement. No differences were shown among the methods used for selection hence can be adapted for breeding in cowpea. Key words: Selection index, scab, thrip and virus resistance, usefulness criteria, yield.
Evaluation of maize (Zea mays L.) performance under minimum and conventional tillage practice in two distinct agroecological zones of Uganda

Maize is one of the major staple foods in Uganda, providing over 40% of Uganda’s daily calorie consumption. Tillage practice is one of the crucial factors that influence crop productivity through maintenance of soil health. The aim of this study therefore is to validate the effect of tillage practice on the vegetative growth and yield of maize in Uganda. The trial was established on-station at Ngetta Zonal Agricultural Research and Development Institute, Lira district and on-farm in Njeru Town Council, Buikwe district. It was laid out in a factorial design with two tillage practices (conventional tillage, CT and minimum tillage, MT) as the main factors and two maize varieties (Longe 10H and Longe 5) as the levels. The results showed significant differences in plant height between the two tillage methods (p< 0.001). Conventional tillage practice had a higher mean maize grain yield per hectare compared to minimum tillage although the difference was insignificant (p<0.332). Thus, the adoption of minimum tillage practice by farmers in Uganda would require investment in organic herbicides in order to control the weeds sustainably and boost maize productivity. Key words: Conventional tillage, minimum tillage, vegetative growth, yield, maize.
Discovering Associations Among Technologies Using Neural Networks for Tech-Mining

In both public and private sectors, critical technology-based tasks, such as innovation, forecasting, and road-mapping, are faced with unmanageable complexity due to the ever-expanding web of technologies which can range into thousands. This context cannot be easily handled manually or with efficient speed. However, more precise and insightful answers are expected. These answers are the fundamental challenge addressed by tech-mining. For tech-mining, discovering the associations among them is a critical task. These associations are used to form a weighted directed graph of technologies called “association tech-graph” which is used for technology development, trend analysis, policymaking, strategic planning, and innovation. In this article, we present a novel method to build an artificial intelligence (AI) agent for automatic association discovery among technologies in a way that matches the quality of the human experts. To this end, neural network-based word embedding methods are exploited to represent technology terms as vectors, and their associations are calculated using similarity measures. To increase the accuracy of the vectors, several crawlers are built to acquire more appropriate training data. Furthermore, we introduce a validation method to measure the accuracy of the AI agent compared to human intelligence, which allows us to discuss the drawbacks of both approaches.
Comparative effects of feeding and duodenal infusion of monensin on digestion in sheep

The effect of monensin on digestion was compared when it was used as feed additive or infused into the duodenum. Six Texel wethers fitted with ruminal, simple duodenal and re-entrant ileal cannulae, divided into three groups, were fed a mixed diet alone (control) or with 33 mg of monensin in feed or infused through the duodenal cannula. The experiment was designed as a 3 × 3 Latin square. Feeding monensin increased (P < 0.05) the amount of OM digested in the rumen and small intestine; infusion into the duodenum had no effect on this parameter. Monensin had no effect on the extent or site of N digestion. No ruminal recycling of monensin was observed since ruminal VFAs were not altered by monensin infusion into the duodenum. VFAs in the hindgut were only modified when monensin was fed (improvement of propionate proportion, P < 0.05). Amylase activity remained unchanged in the intestine whatever the monensin supply. Only fed monensin increased (P < 0.05) trypsin activity. Infused monensin increased the plasm.
Non-Invasive Isthmocele Treatment: A New Therapeutic Option During Assisted Reproductive Technology Cycles?

Background The objective of the study was to evaluate a new medical treatment strategy for infertile patients with isthmocele. Methods This was a retrospective evaluation of the records of infertile patients with symptomatic isthmocele who received non-invasive isthmocele treatment (NIIT) before in vitro fertilization (IVF) treatment cycles. Isthmocele volumes were measured before and after NIIT. The IVF results and isthmocele-related complaints were also analyzed. The patients were treated with a depot gonadotropin-releasing hormone agonist for 3 months before frozen-thawed embryo transfer cycles. Results The mean isthmocele volume was 471.06 ± 182.81 mm3 (range: 289.43 - 765.4 mm3) in fresh cycles, but was reduced to 47.94 ± 29.48 mm3 (range: 18.70 - 105.6 mm3) in frozen-thawed cycles (P < 0.05). Intrauterine fluid was observed in two patients during fresh cycles, but was absent after NIIT during frozen-thawed cycles. There was no brown bloody discharge on the tip of the embryo transfer catheter in any case after NIIT. Two patients became pregnant and underwent term cesarean delivery (25%). Conclusions NIIT can serve as an alternative pretreatment option for patients with isthmocele during IVF cycles.
Effects on Motivation and Implicit Beliefs about Self ability using the Sports Education Model and the Traditional Style in Secondary Education

The methodology employed during physical education sessions can determine students’ motivations and implicit beliefs about their own abilities. The aim of the present study was based on comparing the effects produced on motivation and implicit beliefs about self ability when implementing a Sports Education model and a traditional style. Ninety-three secondary education students participated in the study, with ages ranging from 13 to 15 (13.32 ± 0.62). A total of 54 students took part in the sessions designed according to the Sports Education model and 43 in those following a traditional style. At the beginning and the end of the didactic unit, each student was administered the questionnaire CMEF (Cuestionario de Motivacion en Educacion Fisica) for motivation in physical education and the questionnaire Conceptions of the Nature of Athletic Ability Questionnaire-2 (CNAAQ-2) for implicit beliefs about ability. Results showed significant differences for the Sports Education model in the dimensions of intrinsic motivation, identified regulation, introproyected regulation, and external regulation (p < 0.01). The Sports Education model is optimal to promote motivation; therefore, teachers should consider putting it into practice as a methodology to improve students’ motivation profile.
Classification of High-Spatial-Resolution Remote Sensing Scenes Method Using Transfer Learning and Deep Convolutional Neural Network

The deep convolutional neural network (DeCNN) is considered one of promising techniques for classifying the high-spatial-resolution remote sensing (HSRRS) scenes, due to its powerful feature extraction capabilities. It is well-known that huge high-quality labeled datasets are required for achieving the better classification performances and preventing overfitting, during the training DeCNN model process. However, the lack of high-quality datasets limits the applications of DeCNN. In order to solve this problem, in this article, we propose a HSRRS image scene classification method using transfer learning and the DeCNN (TL-DeCNN) model in a few shot HSRRS scene samples. Specifically, three typical DeCNNs of VGG19, ResNet50, and InceptionV3, trained on the ImageNet2015, the weights of their convolutional layer for that of the TL-DeCNN are transferred, respectively. Then, TL-DeCNN just needs to fine-tune its classification module on the few shot HSRRS scene samples in a few epochs. Experimental results indicate that our proposed TL-DeCNN method provides absolute dominance results without overfitting, when compared with the VGG19, ResNet50, and InceptionV3, directly trained on the few shot samples.
The biology, life history and management needs of a large sciaenid fish, Argyrosomus coronus, in Angola

The West Coast dusky kob Argyrosomus coronus is an understudied yet important fishery species in Angola. During a five-year study (2005–2009), the species was recorded in all fishery sectors, but was most important in the inshore recreational fishery in southern Angola (Cunene Estuary to Namibe). Early juveniles (<300 mm total length, TL) were captured in the offshore artisanal fishery at Praia Pinda, whereas juveniles (300–600 mm TL), subadults (600–870 mm TL) and adults (>870 mm TL) were captured in all fisheries as far north as Namibe, and shoals of large adult fish (>1 000 mm TL) were occasionally captured in the offshore purse-seine commercial fishery between the Cunene Estuary and Lucira. Because some Argyrosomus species are morphologically cryptic, a DNA barcoding method was used to confirm the taxonomic status of the biological samples used in this study. The male:female sex ratio of examined samples was 1:1.4 (n = 225). The length-at-50% maturity was 823 mm and 904 mm TL for males and females respectively. Age-at-50% maturity was 4.4 and 4.3 years for males and females respectively. The periodicity of otolith ring formation was confirmed to be one year using a marginal zone and a chemical marking analysis. Growth (in mm TL) was best described by: Lt = 1 826(1—e−0.12(t + 1.60)). Argyrosomus coronus fed predominantly on fish, mainly Sardinella aurita (62% frequency of occurrence). Early juveniles appeared to frequent the offshore zone (50–100 m depth), moving into the inshore region at approximately 300 mm TL. Juveniles and subadults were resident (57% recaptured at the same site) and were particularly abundant around the mouth of the Cunene Estuary as well as in central and northern Namibia. Adults undertake migrations that correspond with the movement of the Angola–Benguela frontal zone, moving north as far as Gabon in winter and returning to southern Angola in spring, when spawning appeared to take place offshore. There are currently no catch restrictions on A. coronus in Angolan waters. However, declining catches and increasing fishing effort suggest that some management intervention is required, commencing with a proposed closure of the Cunene Estuary mouth region to fishing.
Pilot Design and Allocation for Multi-Cell Massive MIMO Systems With Two-Tier Receiving

This paper investigates pilot design and allocation in multi-cell massive multiple-input multiple-output systems with two-tier receiving. As the length of pilot is limited, the pilots cannot be orthogonal and cause interference. The sum rate as well as the signal-to-interference-plus-noise ratio (SINR) of the system are firstly analyzed. The sum rate upper bound and the asymptotic SINR are derived. The analysis shows that the pilot correlation and the spatial correlation jointly affect the sum rate. Based on this observation, the discrete Fourier transform vectors are employed in designing pilots with various correlation values. Then, with the channel correlation information and the designed pilots, the pilots are allocated to the cells in a greedy way with the object of maximizing the sum rate upper bound. Moreover, the sum rate analysis, the pilot design, and the pilot allocation are extended to the scenario with grouped correlations. Simulation results show that the proposed pilot design and allocation performs better than other pilots and the derived upper bound is effective.
A Comparative Evaluation of Revascularization Done in Traumatized Immature, Necrotic Anterior Teeth with and without Platelet-rich Fibrin: A Case Report

ABSTRACT The aim of this paper is to present two methods of revascularization done in traumatized immature, nonvital anterior teeth using platelet-rich fibrin (PRF) and natural blood clot as a scaffold material. This was performed after disinfection of the root canal space using tri-antibacterial paste. In one tooth, PRF prepared from autologous blood was placed in the canal and in the other tooth, natural bleeding was induced to obtain a fresh blood clot. The patient was recalled regularly at 1, 3, 6, 9, and 12 months’ interval for evaluation. After 12 months, on clinical examination, both teeth showed negative response to percussion and palpation tests but positive response to cold and electric pulp tests. On radiographic examination, the tooth treated with PRF exhibited comparatively faster root lengthening, complete closure of the root apex, more thickening of the root dentinal walls, and narrowing of root canal space compared to conventionally revascularized tooth.

Multiangle, Frequency, and Polarization Radar Measurement of Ice Sheets

Radio echo sounding of polar ice sheets provides important information on the ice bed topography and internal layers. These data have been used by scientists to create 3-D maps of polar ice sheets for climate modeling as well as to reconstruct the climate history that dates back to hundreds of thousands of years. In this article, we present the design and development of three surface-based multichannel radars in the VHF and UHF bands. We provide results from radar data multifrequency and polarization radar data collected over the Greenland ice sheet. All the three radars shared the same digital waveform generator and digitizer, and were installed in and operated on a tracked vehicle. The radars are operated with three different antenna arrays designed for operation over 170–230, 180–340, and 600–900 MHz. The results we obtained sounded more than 2.7 km thick ice with radars operating at frequencies as high as 850 MHz with more than 40 dB signal-to-noise ratio.
