DPIF-Net: a dual path network for rural road extraction based on the fusion of global and local information
Authors: Sun Yuan , Gu Xingfa , Zhou Xiang , Yang Jian , Shen Wangyao , Cheng Yuanlei , Zhang Jin Ming , Chen Yunping 
Published: May 2024

Background
Automatic extraction of roads from remote sensing images can facilitate many practical applications. However, thus far, thousands of kilometers or more of roads worldwide have not been recorded, especially low-grade roads in rural areas. Moreover, rural roads have different shapes and are influenced by complex environments and other interference factors, which has led to a scarcity of dedicated low level category road datasets.

Methods
To address these issues, based on convolutional neural networks (CNNs) and tranformers, this article proposes the Dual Path Information Fusion Network (DPIF-Net). In addition, given the severe lack of low-grade road datasets, we constructed the GaoFen-2 (GF-2) rural road dataset to address this challenge, which spans three regions in China and covers an area of over 2,300 km, almost entirely composed of low-grade roads. To comprehensively test the low-grade road extraction performance and generalization ability of the model, comparative experiments are carried out on the DeepGlobe, and Massachusetts regular road datasets.

Results
The results show that DPIF-Net achieves the highest IoU and F1 score on three datasets compared with methods such as U-Net, SegNet, DeepLabv3+, and D-LinkNet, with notable performance on the GF-2 dataset, reaching 0.6104 and 0.7608, respectively. Furthermore, multiple validation experiments demonstrate that DPIF-Net effectively preserves improved connectivity in low-grade road extraction with a modest parameter count of 63.9 MB. The constructed low-grade road dataset and proposed methods will facilitate further research on rural roads, which holds promise for assisting governmental authorities in making informed decisions and strategies to enhance rural road infrastructure.

Computational fluid dynamics simulation of a quadrupole magnetic sorter flow channel: Effect of splitter position on nonspecific crossover
Authors: Sajja V. S. K. , Kennedy David J. , Todd Paul W. , Hanley Thomas R. 
Published: July 2011

AbstractIn the quadrupole magnetic sorter (QMS) magnetic particles enter a vertical flow annulus and are separated from nonmagnetic particles by radial deflection into an outer annulus where the purified magnetic particles are collected via a flow splitter. The purity of magnetically isolated particles in QMS is affected by the migration of nonmagnetic particles across transport lamina in the annular flow channel. Computational fluid dynamics (CFD) simulations were used to predict the flow patterns, pressure drop and nonspecific crossover in QMS flow channel for the isolation of pancreatic islets of Langerhans. Simulation results were compared with the experimental results to validate the CFD model. Results of the simulations were used to show that one design gives up to 10% less nonspecific crossover than another and this model can be used to optimise the flow channel design to achieve maximum purity of magnetic particles.
Geometrical triple phase boundary length measurement using focused ion beam tomography
Authors: Rivard Tony , Gitzhofer François , Abatzoglou Nicolas 
Published: July 2011

AbstractIn multi‐component materials, triple phase boundary (TPB) is the location where reactions occur. A typical example is the TPB encountered in solid oxide fuel cells at the cathode–electrolyte interface. We proposed a tomographic approach that was developed based on serial sectioning using a focused dual ion beam (FIB) system. For image capture, FIB tomography was coupled with scanning electron microscopy, and differentiation of the composite cathode materials was possible through image contrast adjustment. An algorithm, built on the Hoshen–Kopelman theory, was then applied to measure TPB length. The percentage of the connected TPB line was also calculated with the algorithm for 3D computation. © 2011 Canadian Society for Chemical Engineering
Metrics for evaluating patient navigation during cancer diagnosis and treatment
Authors: Guadagnolo B. Ashleigh , Dohan Daniel , Raich Peter 
Published: July 2011

AbstractBACKGROUND:Racial and ethnic minorities as well as other vulnerable populations experience disparate cancer‐related health outcomes. Patient navigation is an emerging health care delivery innovation that offers promise in improving quality of cancer care delivery to these patients who experience unique health‐access barriers. Metrics are needed to evaluate whether patient navigation can improve quality of care delivery, health outcomes, and overall value in health care during diagnosis and treatment of cancer.METHODS:Information regarding the current state of the science examining patient navigation interventions was gathered via search of the published scientific literature. A focus group of providers, patient navigators, and health‐policy experts was convened as part of the Patient Navigation Leadership Summit sponsored by the American Cancer Society. Key metrics were identified for assessing the efficacy of patient navigation in cancer diagnosis and treatment.RESULTS:Patient navigation data exist for all stages of cancer care; however, the literature is more robust for its implementation during prevention, screening, and early diagnostic workup of cancer. Relatively fewer data are reported for outcomes and efficacy of patient navigation during cancer treatment. Metrics are proposed for a policy‐relevant research agenda to evaluate the efficacy of patient navigation in cancer diagnosis and treatment.CONCLUSIONS:Patient navigation is understudied with respect to its use in cancer diagnosis and treatment. Core metrics are defined to evaluate its efficacy in improving outcomes and mitigating health‐access barriers. Cancer 2011;117(15 suppl):3563–572. © 2011 American Cancer Society.
Numerical modelling of the fibre–matrix interaction in biaxial loading for hyperelastic soft tissue models
Authors: Lu Y. T. , Zhu H. X. , Richmond S. , Middleton J. 
Published: July 2011

SUMMARYThis paper assumes that a neo‐Hookean matrix with neo‐Hookean fibres is representative of soft tissue. Under this assumption, a unit cell model is proposed to investigate the fibre–matrix interfacial stress field for biological soft tissue under biaxial loadings. In this unit cell model, the soft tissue is treated as a composite where the matrix is unidirectionally reinforced with a single family of aligned fibres. The results are compared with the model of Guo et al., which accounts for the fibre–matrix interfacial stress field, and Qiu and Pence's model, which does not proceed from the assumption that the fibres are themselves neo‐Hookean. It is found that the stress representative of the fibre–matrix interface plays an important role in the deformation of the composite, and the model of Guo et al. underestimates this stress under large biaxial deformation.

EEG power and coherence during preschoolers' performance of an executive function battery
Authors: Swingler Margaret M. , Willoughby Michael T. , Calkins Susan D. 
Published: July 2011

AbstractThe current study investigated a set of abilities collectively referred to as executive function (EF). Substantial improvement in EF ability occurs between 3 and 6 years of age (e.g., Carlson [2005] Developmental Neuropsychology, 28(2):595–616). This improvement is thought to reflect changes in brain development, especially in areas of prefrontal cortex and frontal cortex, which occur during this time period (e.g., Luu & Posner [2003] Brain 126:2119–2120). Little work has examined preschoolers' cortical activity during EF tasks, despite the frequent use of performance on such tasks as indirect measures of (pre)frontal functioning. The current study measured continuous EEG activity in 104 preschool aged children as they completed a battery of EF tasks. Changes from baseline to task performance in EEG activity (power, coherence) were used as predictors of EF ability. Results indicated that changes from baseline to task engagement in EEG coherence, but not EEG power, were significantly related to performance on the EF battery in our sample. © 2011 Wiley Periodicals, Inc.

14‐3‐3 proteins regulate retinal axon growth by modulating ADF/cofilin activity
Authors: Yoon Byung C. , Zivraj Krishna H. , Strochlic Laure , Holt Christine E. 
Published: July 2011

AbstractPrecise navigation of axons to their targets is critical for establishing proper neuronal networks during development. Axon elongation, whereby axons extend far beyond the site of initiation to reach their target cells, is an essential step in this process, but the precise molecular pathways that regulate axon growth remain uncharacterized. Here we show that 14‐3‐3/14‐3‐3ς proteins—adaptor proteins that modulate diverse cellular processes including cytoskeletal dynamics—play a critical role in Xenopus retinal ganglion cell (RGC) axon elongation in vivo and in vitro. We have identified the expression of 14‐3‐3/14‐3‐3ς transcripts and proteins in retinal growth cones, with higher levels of expression occurring during the phase of rapid pathway extension. Competitive inhibition of 14‐3‐3/14‐3‐3ς by expression of a genetically encoded peptide, R18, in RGCs resulted in a marked decrease in the length of the initial retinotectal projection in vivo and a corresponding decrease in axon elongation rate in vitro (30–40%). Furthermore, 14‐3‐3/14‐3‐3ς (R1) co‐localized with Xenopus actin depolymerizing factor (ADF)/cofilin (XAC) in RGC growth cones. Inhibition of 14‐3‐3/14‐3‐3ς function with either R18 or morpholinos reduced the level of inactive pXAC and increased the sensitivity to collapse by the repulsive cue, Slit2. Collectively, these results demonstrate that14‐3‐3/14‐3‐3ς participates in the regulation of retinal axon elongation, in part by modulating XAC activity. © 2011 Wiley Periodicals, Inc.

Oosorption in response to poor food: complexity in the trade‐off between reproduction and survival
Authors: Moore Patricia J. , Attisano Alfredo 
Published: July 2011

AbstractPlasticity in reproductive physiology is one avenue by which environmental signals, such as poor quality food, can be coordinated with adaptive responses. Insects have the ability to resorb oocytes that are not oviposited. Oosorption is proposed to be an adaptive mechanism to optimize fitness in hostile environments, recouping resources that might otherwise be lost, and reinvesting them into future reproductive potential. We tested the hypothesis that oosorption is an evolved mechanism by which females can reallocate resources from current reproductive effort to survival and future reproduction, when conditions for reproduction are poor, by examining the reproductive physiology and life‐history outcome under poor quality food in populations of the milkweed bug (Oncopeltus fasciatus) that have adapted to live on sunflower seed. Females fed a diet of pumpkin seeds, known to be a poor host food, had higher levels of ovarian apoptosis (oosorption), lower reproductive output, but no reduction in life span under poor nutrition, as predicted under the oosorption hypothesis. However, the schedule of reproduction was surprising given the “wait to reproduce” assumption of oosorption as early fecundity was unaffected.

Nonlinear multi‐index coordinated control of generator excitation and battery energy storage system
Authors: Li Kang , Wang Jie 
Published: July 2011

SUMMARYThe strong nonlinear nature of the generator and system behavior following a severe disturbance precludes the use of classical linear control techniques. The integration of an energy storage system, such as battery energy storage system (BESS), into a flexible alternating current transmission system device can provide dynamic decentralized active power capabilities and much needed flexibility for mitigating transmission level power flow problems. A model of power system with BESS compensation devices that integrate classic third‐order model of generator and BESS model was deducted and established in this paper. The BESS unit is located near the generator bus terminal in a power system. Using multi‐index nonlinear control design method, BESS and generator excitation were designed by coordinate control scheme for the model above. The controller proposed in this paper is good in improving the dynamic characteristics of state variables, so as to enhance the stable operation capacity of the system. The simulation on single‐machine infinite‐bus power system demonstrates the effectiveness and the practicality of the controller. Copyright © 2011 John Wiley & Sons, Ltd.
Precipitation‐runoff processes in Shimen hillslope micro‐catchment of Taihang Mountain, north China
Authors: Han Shumin , Yang Yonghui , Fan Tong , Xiao Dengpan , Moiwo Juana Paul 
Published: July 2011

AbstractPrecipitation runoff is a critical hillslope hydrological process for downslope streamflow and piedmont/floodplain recharge. Shimen hillslope micro‐catchment is strategically located in the central foothill region of Taihang Mountains, where runoff is crucial for water availability in the piedmont corridors and floodplains of north China. This study analyzes precipitation‐runoff processes in the Shimen hillslope micro‐catchment for 2006–2008 using locally designed runoff collection systems. The study shows that slope length is a critical factor, next only to precipitation, in terms of runoff yield. Regression analysis also shows that runoff is related positively to precipitation, and negatively to slope length. Soil mantle in the study area is generally thin and is therefore not as critical a runoff factor as slope length. The study shows a significant difference between overland and subsurface runoff. However, that between the 0–10 and 10–20 cm subsurfaces is insignificant. Runoff hardly occurs under light rains (<10 mm), but is clearly noticeable under moderate‐to‐rainstorm events. In the hillslope catchment, vertical infiltration (accounting for 42–84% of the precipitation) dominates runoff processes in subsurface soils and weathered granite gneiss bedrock. A weak lateral flow (at even the soil/bedrock interface) and the generally small runoff suggest strong infiltration loss via deep percolation. This is critical for groundwater recharge in the downslope piedmont corridors and floodplains. This may enhance water availability, ease water shortage, avert further environmental degradation, and reduce the risk of drought/flood in the event of extreme weather conditions in the catchment and the wider north China Plain.
