Disentangling drivers of the abundance of coral reef fishes in the Western Indian Ocean

Abstract Aim Understanding the drivers of the structure of coral reef fish assemblages is vital for their future conservation. Quantifying the separate roles of natural drivers from the increasing influence of anthropogenic factors, such as fishing and climate change, is a key component of this understanding. It follows that the intrinsic role of historical biogeographical and geomorphological factors must be accounted for when trying to understand the effects of contemporary disturbances such as fishing. Location Comoros, Madagascar, Mozambique and Tanzania, Western Indian Ocean (WIO). Methods We modeled patterns in the density and biomass of an assemblage of reef‐associated fish species from 11 families, and their association with 16 biophysical variables. Results Canonical analysis of principal coordinates revealed strong country affiliations of reef fish assemblages and distance‐based linear modeling confirmed geographic location and reef geomorphology were the most significant correlates, explaining 32% of the observed variation in fish assemblage structure. Another 6%–8% of variation was explained by productivity gradients (chl_a), and reef exposure or slope. Where spatial effects were not significant between mainland continental locations, fishing effects became evident explaining 6% of the variation in data. No correlation with live coral was detected. Only 37 species, predominantly lower trophic level taxa, were significant in explaining differences in assemblages between sites. Main Conclusions Spatial and geomorphological histories remain a major influence on the structure of reef fish assemblages in the WIO. Reef geomorphology was closely linked to standing biomass, with “ocean‐exposed” fringing reefs supporting high average biomass of ~1,000 kg/ha, while “lagoon‐exposed fringing” reefs and “inner seas patch complex” reefs yielded substantially less at ~500kg/ha. Further, the results indicate the influence of benthic communities on fish assemblages is scale dependent. Such insights will be pivotal for managers seeking to balance long‐term sustainability of artisanal reef fisheries with conservation of coral reef systems.

A Multi-Category Brain Tumor Classification Method Bases on Improved ResNet50

: Brain tumor is one of the most common tumors with high mortality. Early detection is of great significance for the treatment and rehabilitation of patients. The single channel convolution layer and pool layer of traditional convolutional neural network (CNN) structure can only accept limited local context information. And most of the current methods only focus on the classification of benign and malignant brain tumors, multi classification of brain tumors is not common. In response to these shortcomings, considering that convolution kernels of different sizes can extract more comprehensive features, we put forward the multi-size convolutional kernel module. And considering that the combination of average-pooling with max-pooling can realize the complementary of the high-dimensional information extracted by the two structures, we proposed the dual-channel pooling layer. Combin-ing the two structures with ResNet50, we proposed an improved ResNet50 CNN for the applications in multi-category brain tumor classification. We used data enhancement before training to avoid model over fitting and used five-fold cross-validation in experiments. Finally, the experimental results show that the network proposed in this paper can effectively classify healthy brain, meningioma, anaplastic

The purpose of this study is to determine the relationship between self-control and teenage social media addiction (Facebook). This study employs a quantitative approach and purposively samples 102 students in the XII level. The data collection scales used are self-control and social media addiction (Facebook). Data analysis utilizing product moment correlation approaches revealed a negative correlation between self-control and social media addiction of rxy = -0.42; p = 0.000 0.05, indicating that the more the self-control, the lower the social media addiction. And, once again, the lack of self-control correlates with a higher level of social media addiction. As a result, the hypothesis is accepted. According to the research findings, self-control contributes 17.58 percent to social media addiction, while the remaining 82.42 percent is influenced by other factors. …
SOI-LEDs with Carrier Confinement

Silicon-On-Insulator (SOI) technology exhibits significant performance advantages over conventional bulk silicon technology in both electronics and optoelectronics. In this chapter we present an overview of recent applications on light emission from SOI materials. Particularly, in our work we used SOI technology to fabricate light emitting diodes (LEDs), which emit around 1130 nm wavelength with an external quantum efficiency of 1.4 × 10−4 at room temperature (corresponding to an internal quantum efficiency close to 1 %). This is almost two orders of magnitude higher than reported earlier for SOI LEDs. This large improvement is due to three carrier confinement mechanisms: geometrical effects, quantum-size effects, and electric field effects. Our lateral p+/p/n+ structure is powered through two very thin silicon slabs adjacent to the p+/p and n+/p junction. Such use of thin silicon films aims to reduce the p+ and n+ contact area and to confine the injected carriers in the central lowly doped p-region. With this approach, we realized an efficient compact infrared light source with high potential switching speed for on-chip integration applications.

Time and Cost Performance of Design–Build Projects

AbstractThe design–build (DB) delivery method has been widely used in the United States due to its reputed superior cost and time performance. However, rigorous studies have produced inconclusive support and only in terms of overall results, with few attempts being made to relate project characteristics with performance levels. This paper provides a larger and more finely grained analysis of a set of 418 DB projects from the online project database of the Design–Build Institute of America (DBIA), in terms of the time-overrun rate (TOR), early start rate (ESR), early completion rate (ECR), and cost overrun rate (COR) associated with project type (e.g., commercial/institutional buildings and civil infrastructure projects), owners (e.g., Department of Defense and private corporations), procurement methods (e.g., best value with discussion and qualifications-based selection), contract methods (e.g., lump sum and GMP) and LEED levels (e.g., gold and silver). The results show best value with discussion to be th.
Sensor Agent Processing Software (SAPS)

Abstract : The Defense Advanced Research Projects Agency (DARPA) Information Technology Office (ITO) sponsored the Sensor Information Technology (SensIT) program to develop and then demonstrate technologies for large wireless networks. Numerous commercial firms, universities, and research laboratories were given contracts to develop specific technologies required to support the overall objectives. Products from each organization were combined in a common architecture to demonstrate the capability of large wireless networks when applied to a large number of networked sensors collaborating to provide battlefield intelligence. BAE Systems, under contract with Air Force Research Laboratory (AFRL), was primarily responsible for the Sensor Agent Processing Software (SAPS). This report describes the scientific and technical work performed by BAE Systems under Contract F30602-99-C-0159. This includes design and development of the processor application software architecture, development of signal processing algorithms, and implementation of SAPS architecture to support numerous field tests and demonstrations. The report also describes how the BAE Systems' SAPS was combined with other key technologies developed by other SensIT participants to demonstrate that the technologies exist to effectively deploy and utilize large scale sensor networks. The report also addresses efforts undertaken by BAE systems to leverage the SensIT R&D success to develop sensor networks that can be deployed and used in environments such as Afghanistan and Iraq.
Comparative aerodynamic analysis of commercial swimsuits

The primary objective of this research is to investigate and describe the effects of swimsuits' surface profile and seam orientations on aerodynamic drag. Two commercial swimsuits (Speedo LZR and TYR Sayonara) materials were evaluated in a wind tunnel environment using a standard cylindrical experimental arrangement. The effects of swimsuit surface profile and seam orientations on aerodynamic drag were evaluated for a range of Reynolds numbers. The measured drag forces were converted to dimensionless drag coefficients, which were compared for both swimsuits under different conditions. The results show that the material surface structure (roughness and seam orientations) of the swimsuit has significant effect on aerodynamic drag. The seam orientation at 45° has the potential to reduce the drag by around 15% depending on the seam geometry (i.e., seam height, width, etc.) and Reynolds number. The TYR Sayonara swimsuit can provide aerodynamic advantage at low Reynolds number (e.g. below Re = 1.63 × 105) due to lower CD value. The Speedo LZR swimsuit has relative advantage at high Reynolds number (e.g. over Re = 1.63 × 105) compared to TYR Sayonara swimsuit as it has significantly lower CD values at high Reynolds number.
Phytoremediation Efficiency of Some Evergreen Plant Genera for Lead Polluted Soil

A pot experiment was performed to determine the efficiency of phytoremediation of some evergreen plants to lead in a polluted soil. The experiment was a factorial completely randomized design with three replications. The first factor was four evergreen plant genera involved Dodonaea viscosa L. , Myrtus communis L. , Platycladus orientalis L. and Ficus benjamina L. used as phytoremediators. Whereas, the second factor was different concentrations of lead (0, 100, 200 and 300 mg.kg -1 ) which were prepared using laboratory grade PbCl 2 . The results indicated that the highest bioaccumulation factor (BF) (39.15 and 19.39) were observed in Dodonaea viscosa and Ficus benjamina respectively. However, the maximum values of total Pb (127.53, 1084.96 and 106.99 mg.kg -1 ) were detected in Platycladus orientalis , Dodonaea viscosa and Myrtus communis respectively. The values of BF and translocation factor (TF) showed that Dodonaea viscosa is the most effective phytoremediator among the other studied plants.
Performance Analysis Of Hybrid Optical OFDM System With High Order Dispersion Compensation

Orthogonal frequency division multiplexing (OFDM) is an attractive modulation format that recently received a lot of attention in the fiber-optic community. The main advantage of optical OFDM is that it can cope with virtually unlimited amount of inter symbol interference (ISI). In high-speed optical transmission systems, ISI is caused for instance by chromatic dispersion and polarization mode dispersion (PMD),which are serious issues in long-haul systems whose bit rate is higher. High order dispersion such as a third-order and higher-order dispersion effects are not fully compensated using the traditional dispersion compensating devices such as Dispersion compensating fiber (DCF). Thus the received signals at the receiver end would be distorted dramatically, even if only a small outside effect affects the transmission link. The tunable adaptive equalizer (TAE) system is proposed in this work at the receiver end to recover higher-order dispersion which would not be compensated by DCF fiber.
Risk factor identification and contribution to surgery-specific surgical site infection

Background: To identify common risk factors for the future occurrence of SSI across digestive system surgical procedures, thoracic surgery and orthopaedic procedures and quantify what the marginal contribution of explaining the future occurrence of SSI is of risk factors specific to each group of surgeries. Methods: Retrospective data from serial point-prevalence studies, performed at the Erasmus MC University Medical Center, Rotterdam, The Netherlands were used, together with medical data, from 3.250 surgical procedures, during the period January 2013 to 29 June 2014. Common risk factors across three groups of surgical procedures were identified by scanning literature and univariate analysis. A multivariate forward-step logistic regression model was used to identify the marginal contribution of the risk factor specific to each group of surgical procedure using the increase in the Gini coefficient. Results: For digestive system surgical procedures, antibiotic use, temperature, smoking status, age, CRP, thrombocyte, during of surgery and surgical urgency are risk factors for SSI, where the last four were specific to the digestive system group of surgical procedures and increased the Gini coefficient by 9.5% (0.63 to 0.69). Preoperative length of stay, antibiotic use and Leukocyte are risk factors for orthopaedic surgical procedures. Temperature, age and the use of antibiotics were significant for thoracic surgical procedures. Conclusion: ASA class, body mass index (BMI), Preoperative length of stay, diabetes, antibiotic use, age, Leukocyte, temperature and smoking status as general risk factors common to digestive, orthopaedic and thoracic surgical procedures using existing literature and univariate logistic regression. Risk factors for SSI, specific to a surgical procedure group can increase the ability to explain the future occurrence of SSI by 9.5%. The models developed in this study can aid healthcare workers to improve preoperative counselling and help identify potentially modifiable risk factors.
Efficacy of Magnetic Resonance Imaging in BIRADS 3, 4 and 5 Patients Detected on Full Filed Digital Mammography: Our Experience

Aim of the study: To perform Dynamic contrast enhanced MRI of breast in patients with positive findings (BIRADS 3, 4 and 5) detected on screening mammography; to correlate the findings of digital mammography and contrast enhanced MRI of breast with histopathological examinations. Settings and Design: A prospective observation study was conducted at a single centre, i.e. HCG Manavata Cancer Centre. Materials and Methods: Screening mammography was performed on patients with age > 40 years and on patients with age 35 - 40 years having positive family history. The positive mammography was reported and the lesions classified according to BIRADS criteria for mammography. Results: Mammographic examination of the breast lesions yielded an overall sensitivity of 97.67% and a specificity of 85.71%. In our study we combined both morphologic and dynamic parameters and its modification into BIRADS category for lesion classification. The sensitivity of MRI examinations was 97.67% while the specificity was 71.43%. Spiculated margins were encountered only in malignant lesions (p = 0.0006). Statistical correlation was obtained between the pathologically proven benign and malignant lesions regarding their enhancement pattern with p value of <0.001. Conclusion: As per the results, dynamic contrast MRI had high sensitivity but limited specificity. We did not find any significant difference between FFDM and MRI in terms of diagnostic accuracy. The use of DWI showed high specificity at cut off point of ADC value—0.85 mm2/s. Thus, DWI can be used in addition of morphological and dynamic kinetic characteristics to increase specificity of MRI.

Model and Algorithm of JIT Purchase Based on Actual Freight Rate

Based on single vendor and single buyer, vendor supplies buyer with a product, and the vendor split order into many equal shipments to delivery. Aimed at minimizing the total cost of vendor and buyer, JIT purchase model based on actual freight rate was proposed. Actual freight rate is transformed into alternating ranges of a constant charge per kilogram followed by a constant fixed charge. For the actual freight rate, by calculating the solutions for all weight ranges and comparing them, the optimal solution was derived. Numerical results show that the algorithm can obtain the optimal solution, and the model is verified.
Multifrequency optimization of multilayered shields

A procedure for the optimization of planar multilayered shielding structures for magnetic fields, at frequencies for which the quasimagnetostatic description can be adopted, is presented in this paper. The optimum thickness of multilayered shields is found under the constraint of a minimum threshold value for the magnetic shielding effectiveness (SE) at a certain distance from a given source. The design of the shield with respect to the number and type of layers is carried out adopting the particle swarm optimization (PSO) method Multilayered shields composed of selected materials are considered, and the optimal configuration in a source of a periodic triangular-wave current at the frequency of 10 kHz is investigated.
