Roughness Control on Multiphase Flow in Rock Fractures
Authors: Hu Ran , Zhou Chen‐Xing , Wu Dong‐Sheng , Yang Zhibing , Chen Yi‐Feng
Published: October 2019

The roughness of rock fractures induces irregular flow passages and significantly affects the displacement front. Previous studies focus on displacement instabilities in porous media, but how roughness controls displacement patterns in rock fractures remains unclear. Here, we derive a theoretical model that describes the two transitions of drainage displacement patterns from capillary fingering to the crossover to viscous fingering as functions of roughness. The phase diagram predicted by this model exhibits excellent agreement with our experimental results, showing that increasing roughness index λb destabilizes displacement fronts. We further find that in capillary fingering regime the percentage of dissipated energy to the total external work increases from 39% to 61% as λb increases from 0.082 to 0.245. Our work elucidates the mechanism of roughness control on multiphase flow in fractures and provides a basis for developing a rigorous upscaling methodology that relates Darcy‐scale flow behavior to the local fluid displacements via energy dissipation.
A Decade of Water Storage Changes Across the Contiguous United States From GPS and Satellite Gravity
Authors: Adusumilli S. , Borsa A. A. , Fish M. A. , McMillan H. K. , Silverii F.
Published: October 2019

Increased climate variability is driving changes in water storage across the contiguous United States (CONUS). Observational estimates of these storage changes are important for validation of hydrological models and predicting future water availability. We estimate CONUS terrestrial water storage anomalies (TWSA) from 2007–2017 using Global Positioning System (GPS) displacements, constrained by lower‐resolution TWSA observations from Gravity Recovery and Climate Experiment (GRACE) satellite gravity—a combination that provides higher spatiotemporal resolution than previous estimates. The relative contribution of seasonal, interannual, and subseasonal TWSA varies widely across CONUS watersheds, with implications for regional water security. Separately, we find positive correlation between TWSA and the El Niño/Southern Oscillation in the southeastern Texas‐Gulf and South Atlantic‐Gulf watersheds and an unexpected negative correlation in the southwest. In the western United States, atmospheric rivers (ARs) drive a large fraction of subseasonal TWSA, with the top 5% of ARs contributing 73% of total AR‐related TWSA increases.
Multivoxel pattern analysis reveals dissociations between subjective fear and its physiological correlates
Authors: Taschereau-Dumouchel Vincent , Kawato Mitsuo , Lau Hakwan
Published: October 2019

In studies of anxiety and other affective disorders, objectively measured physiological responses have commonly been used as a proxy for measuring subjective experiences associated with pathology. However, this commonly adopted “biosignal” approach has recently been called into question on the grounds that subjective experiences and objective physiological responses may dissociate. We performed machine-learning-based analyses on functional magnetic resonance imaging (fMRI) data to assess this issue in the case of fear. Although subjective fear and objective physiological responses were correlated in general, the respective whole-brain multivoxel decoders for the two measures were different. Some key brain regions such as the amygdala and insula appear to be primarily involved in the prediction of physiological reactivity, whereas some regions previously associated with metacognition and conscious perception, including some areas in the prefrontal cortex, appear to be primarily predictive of the subjective experience of fear. The present findings are in support of the recent call for caution in assuming a one-to-one mapping between subjective sufferings and their putative biosignals, despite the clear advantages in the latter’s being objectively and continuously measurable in physiological terms.

Abnormally localized DLK1 interacts with NCOR1 in non-small cell lung cancer cell nuclear
Authors: Tan Jinjing , Zhang Susu , Li Lin , Mu Jing , Wang Ziyu , Zhang Lina , Jiang Mei , Li Weiying , Yang Xin , Liu Yu , Gao Yanning
Published: October 2019

Delta-like homolog 1 (DLK1) regulates noncanonical Notch signaling pathway as ligand. DLK1 was abnormally expressed in a variety of tumors, affecting tumorigenesis and developments. The biological function of DLK1 toward cell proliferation and signaling activation was controversial across different cell types. Two currently known isoforms of DLK1, which are membrane-tethered isoform and soluble isoform, are believed to be the key of DLK1 dual behaviors. While these isoforms are not enough to explain the phenomena, our observations offer the possibility of a third isoform of DLK1. In the present study, we verified the nuclear localization of DLK1 in lung cancer cells. The nuclear localized DLK1 was observed in 107 of 351 non-small cell lung cancer (NSCLC) samples and was associated with tissue differentiation and tumor size. Through co-immunoprecipitation (co-IP) combined mass spectrometry (MS), we identified nuclear receptor corepressor 1 (NCOR1) as DLK1’s novel interaction protein and confirmed their interaction in nuclear. We analyzed the expression of NCOR1 in two independent cohorts and demonstrated that NCOR1 is a tumor suppressor and has prognosis potential in lung squamous carcinomas. At last, we analyzed the colocalization of DLK1 and NCOR1 in 147 NSCLC samples by immunohistochemistry (IHC). The result indicated NCOR1 might participate with nuclear localized DLK1 in regulating cell differentiation.
New video encryption schemes based on chaotic maps
Authors: Elkamchouchi Hassan , Salama Wessam M. , Abouelseoud Yasmine
Published: October 2019

Two new encryption algorithms for secure video transmission are proposed in this paper. The two algorithms employ different types of chaotic maps to generate the keystream for encrypting the video frames. Both algorithms involve a substitution step and a permutation step to achieve confusion and diffusion requirements. For efficient transmission, the video file is compressed before being encrypted. In the basic implementation of both algorithms, MPEG‐2 standard is used for compression. However, the algorithms are shown to be compliant with other compression techniques. In the permutation step, the effect of the block size used in the shuffling process is examined. Smaller blocks result in increasing the processing time, while reducing both the correlation between adjacent pixels and the peak‐signal‐to noise ratio of an encrypted frame. The use of a Feistel structure is investigated to enhance security and its negative impact on the encryption time is demonstrated. The experimental results of the two proposed schemes confirm that they represent different tradeoffs between security and computational efficiency. Both schemes are sensitive to slight variations in the encryption key as apparent from the obtained differential measures. The conducted comparative study shows the competitiveness of the proposed schemes to existing schemes in literature.
Research on fingerprint classification based on twin support vector machine
Authors: Ding Shifei , Shi Songhui , Jia Weikuan
Published: October 2019

Fingerprint classification is one of the core steps of fingerprint recognition and directly relates to the accuracy of recognition. For this reason, a fingerprint classification method based on Twin Support Vector Machine (TWSVM) is studied. First, the Gabor filter is used to extract texture features from fingerprint images. Second, a multi‐class model based on TWSVM is constructed by using the ‘one‐versus‐all’ strategy and the binary tree method, respectively. The quantum particle swarm optimisation algorithm is used to optimise the parameters in the model. Then the fingerprints are divided into five categories using the optimised model. Finally, the classification model is evaluated using fingerprint images from the NIST‐4 database. The experimental results show that applying the TWSVM to fingerprint classification can get good classification results.
Fingerprint location algorithm based on K‐means for spatial farthest access point in Wi‐Fi environment
Authors: Wu Chun‐Ming , Qi Sen‐Nan , Zhao Chen
Published: October 2019

The main problems of location fingerprint are the timeliness and accuracy of location. However, the huge fingerprint database and complex location information will make the location process extremely complex and time‐consuming. On the basis of introducing the basic idea of the strongest access point (AP), a location fingerprints recognition algorithm based on K‐means clustering of the farthest spatial AP of Wi‐Fi is proposed. This algorithm improves the traditional K‐means algorithm, chooses the optimal initial clustering centres based on the idea of the longest distance in space, and optimises the fingerprint database by using the improved algorithm to complete the rough location of fingerprint position. Then, the weight coefficients of AP are introduced into the Euclidean distance of the weighted k ‐nearest neighbour algorithm to enhance the contribution of spatial AP and achieve accurate location of the location fingerprint algorithm. The simulation results show the effectiveness of the algorithm. The algorithm not only effectively reduces the clustering time and the number of matched fingerprints, but also reduces the computational complexity of the algorithm, and reduces the negative impact on the real‐time and accuracy of the positioning system.
Design and synthesis of bactericidal block copolymer for preparing durably antibacterial PA6 fibre
Authors: Yin Shanshan , Zhang Xin , Meng Yang , Su Juanjuan , Han Jian
Published: October 2019

Polymer fibres are widely used in various materials in contact with the human body. As bacterial contamination may lead to the emergence of disease, it is necessary to provide fibres with durably antibacterial properties. In this work, based on 4‐vinyl pyridine, fluorine‐containing monomers and acrylic acid monomers, new quaternary ammonium salt polymer containing fluorine (NP) were prepared by solution polymerisation, and then the antibacterial composite fibre was prepared by melt spinning of the NP (9 wt%) and Nylon 6 fibre (PA6). The structure and properties of NP and composite fibres were characterised, respectively. The results indicated that the water contact angle of NP reached 104°, the pyrolysis temperature was 302°C, and the interface interaction between NP and PA6 was good, which could achieve more uniform dispersion in Nylon 6 matrix. In addition, the composite fibre decreased obviously the number of colony‐forming units within 24 h (the bactericidal rate was 99.99% against E. coli and 99.81% against S. aureus) compared with pure PA6 fibre. The composite fibre was a good durably antibacterial material, which could still inactivate over 96% inoculated E. coli and S. aureus after washing 7 days.
Local Bubble contribution to the 353-GHz dust polarized emission
Authors: Skalidis R. , Pelgrims V.
Published: October 2019

It has not been shown so far whether the diffuse Galactic polarized emission at frequencies relevant for cosmic microwave background (CMB) studies originates from nearby or more distant regions of our Galaxy. This questions previous attempts that have been made to constrain magnetic field models at local and large scales. The scope of this work is to investigate and quantify the contribution of the dusty and magnetized local interstellar medium to the observed emission that is polarized by thermal dust. We used stars as distance candles and probed the line-of-sight submillimeter polarization properties by comparing the emission that is polarized by thermal dust at submillimeter wavelengths and the optical polarization caused by starlight. We provide statistically robust evidence that at high Galactic latitudes (|b| ≥ 60°), the 353 GHz polarized sky as observed byPlanckis dominated by a close-by magnetized structure that extends between 200 and 300 pc and coincides with the shell of the Local Bubble. Our result will assist modeling the magnetic field of the Local Bubble and characterizing the CMB Galactic foregrounds.
Multiple retrograde substructures in the Galactic halo: A shattered view of Galactic history
Authors: Koppelman Helmer H. , Helmi Amina , Massari Davide , Price-Whelan Adrian M. , Starkenburg Tjitske K.
Published: October 2019

Aims. Several kinematic and chemical substructures have been recently found amongst Milky Way halo stars with retrograde motions. It is currently unclear how these various structures are related to each other. This Letter aims to shed light on this issue.

Methods. We explore the retrograde halo with an augmented version of the Gaia DR2 RVS sample, extended with data from three large spectroscopic surveys, namely RAVE, APOGEE, and LAMOST. In this dataset, we identify several structures using the HDBSCAN clustering algorithm. We discuss their properties and possible links using all the available chemical and dynamical information.

Results. In concordance with previous work, we find that stars with [Fe/H] < −1 have more retrograde motions than those with [Fe/H] > −1. The retrograde halo contains a mixture of debris from objects like Gaia-Enceladus, Sequoia, and even the chemically defined thick disc. We find that the Sequoia has a smaller range in orbital energies than previously suggested and is confined to high energy. Sequoia could be a small galaxy in itself, but since it overlaps both in integrals-of-motion space and chemical abundance space with the less bound debris of Gaia-Enceladus, its nature cannot yet be fully settled. In the low-energy part of the halo, we find evidence for at least one more distinct structure: Thamnos. Stars in Thamnos are on low-inclination, mildly eccentric retrograde orbits, moving at vϕ ≈ −150 km s−1, and are chemically distinct from the other structures.

Conclusions. Even with the excellent Gaia DR2 data, piecing together all the fragments found in the retrograde halo remains challenging. At this point, we are very much in need of large datasets with high-quality high-resolution spectra and tailored high-resolution hydrodynamical simulations of galaxy mergers.

Despite relatively intensive work on the development of inflorescence primordia during grapevine growth in season one, some informational gaps are present in the flower and floral organ development in the season two. In addition, concurrents events of phenology and formation of flowers and floral parts has not been dealt with. With the aid of digital imaging, this research had three objectives; a) describe the developmental events that take place during and after bud break in the buds and in the individual flowers in terms of differentiation, b) match these events with phenological stages, and c) determine size-related growth of the floral organs. After careful dissecting and examination of the samples under microscopy, taken ever 5-10 days between March 20 and May 10 in 2016, the results indicated that highly esteemed works regarding the reproductive anatomy of grapevines needed some additional stages to fully describe events in the stamen and pistil primordia after the appearance of petal primordia. Five intermediate stages were added to the stages of “formation of flowers”. Differentiation of inflorescence and individual flowers occurred in the second season as the buds swelled in the spring. Stamens and pistil could be seen about 3 weeks later and completed their initial growth in another 3 weeks. Flower primordia was visible on April 1 and showed a more than 9-fold increase over the course of 5 to 6 weeks. flowers increased their width and their length more than 9- and 15-fold, respectively, between stage 8.1 (April 1) and 10.3 (May 10). At first, they were wider than they were longer, but at later stages they grew longitudinally. Reproductive organ primordia were visualized around the time of 2-4 leaves separated on the shoots. Signs of generative parts become apparent in late April. Anthers were the smallest in the flower. Filaments, on the other hand, elongated almost 7-fold in a period of 20 days. Gynoecium growth was the most impressive and total pistil length increased from 52.8 to 162 μm, ovary width from 40.4 to 99.8 μm, and stigma diameter from 9.96 to 44.9 μm in twenty days. By the time the pistil took its final shape, 6-8 leaves grew on the shoot during which inflorescence could also be seen.

Objective We investigated the effects of eye movement with PNF neck
movement on trunk stability and standing position balance ability of chronic
stroke patients.

Methods A total of 30 patients were randomly divided into EMPN group
and CON group. EMPN group was performed 60 min three times a week for 8
weeks in eye movement and PNF neck movement. CON group performed
conservative treatment for 60min. The trunk stability was measured by the
Trunk impairment scale (TIS) and the standing balance ability test was
performed by Center of Pressure (COP), Limited of Stability (LOS), Berg
Balance Scale (BBS) and Functional Reach Test (FRT).

Results There was a significant difference (P<0.05) between
before and after training in both groups, and EMPN group showed significant
improvement in both groups.

Conclusions In this study, we confirmed oculogyration and neck
movement by PNF have positive effects on the trunk stability and the
standing position balance ability of chronic stroke patients.

Published: October 2019

A previous study showed that the meroterpenoid-rich fraction of an ethanolic extract of Sargassum serratifolium (MES) stimulated adipose tissue browning and inhibited diet-induced obesity and metabolic syndrome. Sargaquinoic acid (SQA) is a major component in MES. We investigated the effects of SQA on the differentiation of preadipocytes to the beige adipocytes. SQA was treated in 3T3-L1 adipocytes differentiated under a special condition that has been reported to induce the browning of adipocytes. SQA at 10 µM reduced lipid accumulation by approximately 23%. SQA at 2.5 – 10 µM induced the differentiation of white adipocytes to beige adipocytes partially by increasing the mitochondrial density and the expression of beige/brown adipocyte markers. In addition, SQA activated lipid catabolic pathways, evidenced by the increased expression levels of perilipin, carnitine palmitoyltransferase 1, and acyl-CoA synthetase long-chain family member 1. As a partial mechanism, biochemical and in silico analyses indicate that SQA activated AMP-activated protein kinase signaling in adipocytes.

Published: October 2019

An iodine-mediated oxidative cyclization reaction between 2-(pyridin-2-yl)acetate derivatives and different alkynes has been developed, which provides regioselective and chemoselective syntheses of multiply substituted indolizines under modified reaction conditions. Plausible mechanisms have been proposed to explain the selective syntheses of indolizines. This protocol can be also applied to the stepwise synthesis of 2,2′-biindolizines.

Valve prosthesis have played an important role in the management of patients with valvular heart disease. However, the prosthetic heart valves used are not without complications. Almost all prosthetic heart valves are obstructive compared with native valves and associated with physiological washing jets. Because of shielding and artifacts it is very difficult to assess the prosthetic valve with TTE. Multiple thrombi and aortomitral continuity detection is cumbersome by TTE. Multiple angulations and off axis view in TEE help not only to characterize the prosthetic heart valve but also gives a three-dimensional surgical view to aid in reaching a diagnosis.

Gene therapy using recombinant adeno-associated virus (AAV) has induced sustained long-term coagulation human factor IX (hFIX) levels in hemophilia B (HB) patients. However, asymptomatic transient liver toxicity was observed at high vector doses, highlighting the need to improve the potency of these vectors. We report the generation of an AAV transgene cassette containing the hyperfunctional hFIX-E456H variant showing improved binding to platelets, with a comparison to wild-type hFIX (hFIX-WT) and hFIX-R384L variant (Padua) transgenes, containing F9 truncated-intron 1 (I1). In vitro specific activity was increased by 3.2- and 4.2-fold with hFIX-E456H and hFIX-R384L variants compared with hFIX-WT, using chromogenic assay, and by 7-and 8.6-fold with hFIX-E456H and hFIX-R384L variants compared with hFIX-WT, using one-stage assay. The transgenes were packaged into single-stranded AAV2/8 vectors that were tail vein injected at 5 × 109, 2 × 1010, and 5 × 1010 vg per mouse in HB mice. Plasma FIX activity level, assessed by chromogenic assay, was up to fourfold higher for hFIX-E456H compared with hFIX-WT and was not different compared with hFIX-R384L, among the three dose cohorts. Overall, the in vivo specific activity was increased by threefold for hFIX-E456H and 4.9-fold for hFIX-R384L compared with hFIX-WT. At the lower dose of 5 × 109 vg, the blood loss was significantly lower for hFIX-E456H compared with hFIX-WT, but did not differ compared with hFIX-R384L. The results found for the hFIX-E456H variant indicate that it might be a suitable alternative for gene therapy of HB.

Background Limited knowledge exists on the association between intake of long-chained n-3 polyunsaturated fatty acids (n-3 PUFAs) and risk of recurrence and all-cause mortality in patients with venous thromboembolism (VTE).

Objectives This article investigates whether intake of marine n-3 PUFAs was associated with risk of recurrence and mortality in patients with incident VTE.

Methods A total of 595 patients with incident VTE and available data on n-3 PUFA intake were derived from the Tromsø Study surveys 4 (1994–1995) and 6 (2007–2008). Weekly intake of n-3 PUFAs was categorized as low, medium, and high based on tertiles. Recurrent VTEs and all-cause mortality were registered up to December 31, 2016. Hazard ratios (HRs) were calculated using Cox regression models with the low intake category as reference.

Results There were 98 recurrent VTEs and 227 deaths during follow-up. Overall, we found no association between intake of n-3 PUFAs and risk of recurrent VTE. However, inverse associations were found for high intakes in patients with unprovoked VTE (HR 0.45, 95% confidence interval [CI]: 0.20–1.01), cancer-free patients (HR 0.51, 95% CI: 0.27–0.95), and deep vein thrombosis (DVT) patients (HR 0.49, 95% CI: 0.24–0.97). The inverse associations were more evident when follow-up was restricted to the time after discontinuation of anticoagulant therapy. No association was observed between intake of n-3 PUFAs and mortality after incident VTE.

Conclusion A high dietary intake of marine n-3 PUFAs was associated with lower risk of recurrent VTE after unprovoked index events, DVT, and in cancer-free patients.

Published: October 2019

Graphical Processing Units (GPUs) are a powerful alternative to central processing units, especially for data-parallel, video-rate processing of large data volumes. In the complex scenario of high-performance, multichannel Time Correlated Single Photon Counting (TCSPC), a huge amount of data is potentially generated by the acquisition system. Exploiting a dedicated, external, programmable elaboration unit enables a high degree of flexibility to perform different types of analysis. In this paper, we present a GPU-based application that leverages the common unified device architecture application programming interface for video-rate and accurate lifetime extraction from TCSPC data acquired at a rate of up to 10 Gbit/s.
Nanoscale tensile strain in perfect silicon crystals studied by high-resolution X-ray diffraction
Authors: Cusatis Cesar
Published: October 2019

A device was designed, built, and tested to apply small tensile strain to perfect single silicon crystals. It was used on the second axis of a double crystal diffractometer to obtain controllable strain fields. The strain field quality was evaluated by double crystal X-ray diffractometry. The dependence of atomic plane distances on applied stress was determined. Stress-strain curves were obtained from fitted rocking curves in the Bragg-Bragg and Bragg-Laue configurations. These results show that it is possible to obtain a tensile strained lattice with quality suitable for X-ray optics.

Published: October 2019

Carbon ion implantation mediated blue photoluminescence (PL) and the corresponding bluish white phosphorescence of anodic aluminum oxide (AAO) are presented. In particular, the observed 465 nm luminescence is found to be more sensitive to carbon, while its lifetime is raised to its maximum from 6.7 to 10.4 μs at a fluence of 1 × 1016 ions/cm2. The observed phenomenon seems to be associated with the formation of oxygen vacancy (V0) via carbon ion enhanced modification of local AlO6 octahedral symmetry, as revealed from X-ray absorption spectroscopy at O-K edge, and also consistent with X-ray photoelectron spectroscopy (XPS). Detailed XPS analysis indicates the preference of carbon at the Al sites, rather than at O for both octahedral and tetrahedral structures, and form CAl cationic impurity, consistent with our density functional theory calculation. Further, carbon ion implantation driven enhanced PL lifetime is shown to be associated with energy transfer between V0 and the vicinal CAl. This work shows the potential of carbon doped AAO as a future candidate for developing rare earth free nontoxic phosphor.
