Detecting Colluding Inter-App Communication in Mobile Environment

The increase in computing capabilities of mobile devices has, in the last few years, made possible a plethora of complex operations performed from smartphones and tablets end users, for instance, from a bank transfer to the full management of home automation. Clearly, in this context, the detection of malicious applications is a critical and challenging task, especially considering that the user is often totally unaware of the behavior of the applications installed on their device. In this paper, we propose a method to detect inter-app communication i.e., a colluding communication between different applications with data support to silently exfiltrate sensitive and private information. We based the proposed method on model checking, by representing Android applications in terms of automata and by proposing a set of logic properties to reduce the number of comparisons and a set of logic properties automatically generated for detecting colluding applications. We evaluated the proposed method on a set of 1092 Android applications, including different colluding attacks, by obtaining an accuracy of 1, showing the effectiveness of the proposed method.
The impact of authentic leadership on employee creativity in Vietnam: a mediating effect of psychological contract and moderating effects of subcultures

ABSTRACT This study examines the impact of authentic leadership on employee creativity in Vietnamese firms. Relational psychological contract was tested as a mediator while subcultural variables act as moderators. Data were collected from 533 employees in 19 enterprises in Hanoi and Hochiminh City. Results confirm the direct impact of authentic leadership on employee creativity and partial mediating effect of relational psychological contract. Moreover, regional (North vs. South) and generational (pre-1975 born vs. post-1975 born) differences moderated these relationships. Finally, the moderating impacts of public work experience and gender were also established. Theoretical and practical implications were discussed.
Toward a Doctrine of Socially Responsible Marketing (SRM): A Macro and Normative-Ethical Perspective

In this conceptual article, the authors use a macro-level analysis and normative ethical theory to delineate and to explicate a doctrine of socially responsible marketing (SRM). Applying a theory-in-formation approach, we postulate a literature-informed definition of SRM. We discuss why a macro and normative-ethical rather than a micro and positive-descriptive perspective is essential to justifying the elements of SRM. We explore and explain why the roots of an authentic doctrine of SRM can be discerned from the literatures of marketing history, corporate social responsibility, institutional economics and moral philosophy. In so doing, the mandate to engage in socially responsible marketing is shown to be anchored in a social contract. This conception offers three essential elements of SRM—corporate citizenship, stakeholder orientation and social/ecological sustainability—each of which augers a pro-social rather than instrumental-financial approach to marketing practice. We recommend a specific normative-ethical standard, embodied in distributive justice, to best evaluate SRM. We counsel adopting a macromarketing perspective of constructive engagement for those seeking responsible marketing for a better society and world. Finally, we offer a short research agenda for advancing Marketing’s embrace of SRM.
Pathways and Analytical Tools in Degradation Studies of Organic Pollutants

All chemical compounds may undergo a variety of processes resulting from chemical, biological, or photochemical reactions. Depending on the environmental compartment in which organic compounds are present (e.g., soil, benthic sediments, surfacewaters, and groundwaters), they can undergo slow changes resulting from different chemical, physical, biological, or photochemical processes. In this study, different degradation pathways for selected persistent organic pollutants under varying conditions are presented. The problem of intermediate products that form during the degradation of substances, the toxicity of substances that are the products of organic compounds degradation, and the ways to identify such substances have been discussed.
Novel Porous 3D Network Structure Formed by Self-Assembly of Tetrakis(phthalimide) Palladium(II) Complex

A disodium tetrakis(phthalimide) palladium(II) complex, [Na2Pd(phthal)4] (1), was synthesized by reaction of four phthalimide molecules with Pd(OAc)2 in the presence of Et3N. The above and below axial sites of the Pd coordination plane formed the spaces suitable for capturing Na+ ions, which were coordinated with the four imidato oxygen atoms. The complex 1 was linked through the Na+ ions bridged by the water molecules, building an infinite chain structure along the crystallographic a axis. The four phthalimidato moieties contacted in the four orthogonal directions together through their π-π stacking interaction. Such a self-assembly of molecule 1 constructed nanopores with a pore size of ca. 3 × 4 Å in the crystals.
Effect of semen extender supplementation with sericin on post-thaw dairy bull sperm quality and lipid peroxidation

Silk sericin plays a protective role in a variety of mammalian cells during cryopreservation. This study aimed to determine the effects of sericin supplementation to a freezing extender on sperm quality and lipid peroxidation in dairy bull sperm cryopreservation. Each semen sample of five Holstein-Friesian crossbred bulls was divided into four aliquots and diluted in a tris-egg yolk extender supplemented with different concentrations of sericin [0%, 0.25%, 0.5%, and 1.0% (wt/vol)]. Sperm motility (CASA), viability, acrosome integrity, mitochondrial membrane potential (fluorescent staining) and lipid peroxidation (malondialdehyde – MDA test) were analysed. The results show that the 0.25% and 0.5% sericin groups had the highest total sperm motility (P < 0.05). Sperm viability, acrosome integrity, and mitochondrial function were higher in the group supplemented with 0.25% sericin compared to the control and 1.0% (P < 0.05). Sericin supplementation with 0.25% and 0.5% significantly decreased MDA concentrations compared with the control (P < 0.05). In conclusion, supplementation of the semen freezing extender with sericin at the concentration of 0.25% significantly improved the post-thaw semen quality and reduced lipid peroxidation in Holstein-Friesian crossbred bulls.
A robust visual odometry based on RGB-D camera in dynamic indoor environments

To solve the accurate positioning problem of mobile robots, simultaneous localization and mapping (SLAM) or visual odometry (VO) based on visual information are widely used. However, most visual SLAM or VO cannot meet the accuracy requirements in dynamic indoor environments. This paper proposes a robust visual odometry based on deep learning to eliminate feature points matching error. However, when a camera and dynamic objects are in relative motion, the frames of camera will produce ghosting, especially in high-dynamic environments, which bring additional positioning error; in view of this problem, a novel method based on the average optical flow value of the dynamic region is proposed to identify feature points of the ghosting, and then the feature points of the ghosting and dynamic region are removed. After the remaining feature points are matched, we use a non-linear optimization method to calculate the pose. The proposed algorithm is tested on TUM RGB-D dataset, and the results show that our VO improves the positioning accuracy than other robust SLAM or VO and is strongly robust especially in high-dynamic environments.
Study on Influence of Joint Orientation on Rock Engineering Properties for Mining and Infrastructure Design

Rock strength is the most important parameter for mining and infrastructure design. Accurate determination of rock strength is needed as a basis for implementing safe and economical rock engineering projects such as tunnels, open pit mines, and slope cutting for roadways. Rock is heterogeneous, anisotropic, and discontinuous materials. The discontinuities can be found as joints, faults, fissures, bedding, etc. In rock mechanics, the term of joint is generally used to represent all types of discontinuities. Joints are the planes of weakness in rock masses and can be found in various geometrical shapes, depending on past geological processes. This research briefly focuses to study the influence of joint orientation on rock strength based on UCS test. Application of this research could be recommend applying for mining and infrastructure design.
Surface area and porosity of primary silicate minerals

Abstract Surface area is important in quantifying mineral-water reaction rates. Specific surface area (SSA) was measured to investigate controls on this parameter for several primary silicate minerals (PSM) used to estimate rates of weathering. The SSA measured by gas adsorption for a given particle size of relatively impurity-free, laboratory-ground samples generally increases in the order: quartz ≈ olivine ≈ albite < oligoclase ≈ bytownite < hornblende ≈ diopside. Reproducibility of BET SSA values range from ±70% (SSA < 1000 cm2/g) to ± 5% (SSA > 4000 cm2/g) and values measured with N2 were observed to be up to 50% larger than values measured with Kr. For laboratory-ground Amelia albite and San Carlos olivine, SSA can be calculated using log (SSA, cm2/g) = b + m log (d), where d = grain diameter (μm), b = 5.2 ± 0.2 and m = -1.0 ± 0.1. A similar equation was previously published for laboratory-ground quartz. Some other samples showed SSA higher than predicted by these equations. In some cases, high SSA is attributed to significant second phase particulate content, but for other laboratory-ground samples, high SSA increased with observed hysteresis in the adsorption-desorption isotherms. Such hysteresis is consistent with the presence of pores with diameters in the range 2 to 50 nm (mesopores). In particular, porosity that contributes to BET-measured SSA is inferred for examples of laboratory-ground diopside, hornblende, and all compositions of plagioclase except albite, plus naturally weathered quartz, plagioclase, and potassium feldspar. Previous workers documented similar porosity in laboratory-ground potassium feldspar. Surface area measured by gas adsorption may not be appropriate for extrapolation of interfacelimited rates of dissolution of many silicates if internal surface is present and if it does not dissolve equivalently to external surface. In addition, the large errors associated in measuring SSA of coarse and/or impurity-containing silicates suggest that surface area-normalized kinetics in both field and laboratory systems will be difficult to estimate precisely. Quantification of the porosity in laboratory- ground and naturally weathered samples may help to alleviate some of the discrepancy between laboratory- and field-based estimates of weathering rate
Geometry Embedded Multi-Task Network for Lane Detection and Classification

Lane detection and classification are key and fundamental problems in the field of autonomous driving. Deep learning based multi-task network is commonly built with convolutional neural networks (CNNs) to handle these problems. Although existing methods have demonstrated the capability to capture the pixel-level representation and global guidance, the local geometric relationship of lanes are not taken into account to deal with the lanes with weak appearance coherence. This paper proposes geometry embedded multi-task network (GEMNet) with three branch layers, including bounding box regression, lane mask and lane classification. Convolutional operations are applied to feature maps generated by the top hidden layer of bounding box regression branch to explore the semantic context via geometric relationship. Moreover, it is able to facilitate the weight optimization in the shared layers and other branch layers simultaneously. GEMNet is evaluated on Cordova1 and Washington1 datasets, and Experimental results show that the proposed method outperforms the state-of-the art approaches. F1-Score can reach 0.906 and 0.881 with respect to Cordova1 and Washington1 datasets, respectively.
Sulfur deficiency of rice plants in the Lower Volta area, Ghana

Abstract Rice plants were grown in pots under submerged conditions using a soil from the Lower Volta area in Ghana. Plants experienced severe sulfur deficiency when sulfur was not applied, and responded positively to the addition of sulfur. The relative deficiencies in the soil's nutrient supply were in the order of sulfur ≫phosphorus > potassium = nitrogen. The critical levels for achieving 90% shoot growth at the maximum tillering stage were 1.0 to 1.1 g total-S kg-1 DM (shoot dry matter), 26 to 30 of the total-N/total-S (N/S) ratio, 0.10 to 0.15 g sulfate-S kg-1 DM, and 0.05 to 0.15 of the sulfate-S/total-S ratio. A deficiency diagnosis with a single variable often led to an error of judgement, since several criteria showed a C-shaped response curve for plant growth, and a marginally unbalanced nutrient status induced a positive value in any of the criteria. Therefore, when a sulfur shortage being diagnosed, the evaluation should take several variables into account. The maximum quantity of sulfur neede.
Clinical Analysis of Castleman's Disease of the Lacrimal Gland

Objective To explore the clinical manifestations, imaging characteristics, and pathological characteristics of Castleman's disease of the lacrimal gland, enhance the knowledge of the disease, and improve the level of its diagnosis and treatment. Methods In the retrospective study, the data of 5 patients diagnosed with Castleman's disease of the lacrimal gland in Tianjin Medical University Eye Hospital from 2014 to 2018 were analyzed, and the relevant literature was reviewed. Results All the 5 patients were confirmed by pathological examination. Clinical manifestations were characterized by mass occupying lesions in the lacrimal gland area, without obvious pain, accompanied by eyelid swelling and ptosis, as well as space-occupying symptoms. Imaging examination showed that there was a soft tissue mass in the enlarged lacrimal gland area, and the mass was rich in blood flows while showing no obvious specificity, which could invade the surrounding muscles. All patients underwent surgical resection. Pathological results showed that 1 case was of the hyaline-vascular type, 3 cases were of the plasma cell type, and 1 case showed malignant transformation to plasma cell tumor. Conclusion Castleman's disease of the lacrimal gland is a rare orbital lymphoproliferative disease lacking specificity in clinical manifestations and imaging examination. As there are difficulties in differentiating the disease from orbital inflammatory pseudotumor and orbital lymphoma, its diagnosis still depends on pathological examination. The disease is mainly treated with surgical resection, and the pathological type is determined postoperatively.
INVESTIGATION OF FLOW CHARACTERISTICS AND VORTEX FORMATIONS OF LAMBDA WING AT HIGH ANGLES OF ATTACK

It is well known in literature that further stages of flow separation and vortex breakdown around wings can be able to cause stall of wings. These formations must be investigated carefully for new plane types. However, some limited studies are available, especially on lambda wing for high angles of attack. In this study, effect of angle of attack on flow characteristics and vortex breakdown around a lambda wing is investigated with a constant Reynolds number of 10000. Computational fluid dynamic analysis is used and results of high angles of attack of the wing are given up to 45 which are not available in literature. Open water channel simulation is used. Vortex breakdown initially begins at an angle of 17 and it almost reaches to tip of wing when angle of attack is equal to 25. Vortices get stronger at further increments of angle of attack and they become to nearly equal length of wing at 45. Rounding effect of leading edges is investigated for decreasing vortex magnitudes. Streamline, particle injection, iso-value of vortices and location of stagnation points are given, and they are discussed in detail.
Improved Friction and Wear Properties of Al6061-Matrix Composites Reinforced by Cu-Ni Double-Layer-Coated Carbon Fibers

The friction and wear properties of an Al6061 alloy reinforced with carbon fibers (CF) modified with Cu-Ni bimetallic layers were researched. Cu-Ni double layers were applied to the CF by electroless plating and Al6061-matrix composites were prepared by powder metallurgy technology. The metal-CF/Al interfaces and post-dry-wear-testing wear loss weights, friction coefficients, worn surfaces, and wear debris were characterized. After T6 heat treatment, the interfacial bonding mechanism of Cu-Ni-CF changed from mechanical bonding to diffusion bonding and showed improved interfacial bonding strength because the Cu transition layer reduced the fiber damage caused by Ni diffusion. The metal–CF interfacial bonding strongly influenced the composite’s tribological properties. Compared to the Ni-CF/Al and Cu-CF/Al composites, the Cu-Ni-CF/Al composite showed the highest hardness, the lowest friction coefficient and wear rate, and the best load-carrying capacity. The wear mechanisms of Cu-Ni-CF/Al composite are mainly slight abrasive wear and adhesive wear.
Source Fingerprints for Volatile Non-Methane Hydrocarbons

Non-methane hydrocarbon (NMHC) source profiles consisting of 35 hydrocarbon species were measured for vehicle and petroleum refinery emissions. Refueling emissions were found to be sensitive to the grade and volatility class of fuel and to be composed mainly of saturated hydrocarbons such as n-butane and 2-methy I butane. Unsaturated and aromatic hydrocarbons, which are released from the tailpipe of vehicles as products of combustion and unburned fuel, were more prevalent in roadway emissions comprising approximately 34 percent of the total NMHCs. Cold-start emissions were nearly indistinguishable from the roadway emission profile. The only significant differences were in toluene, ethylene and acetylene, which may be related to the efficiency of combustion when the vehicle is initially started. Saturated hydrocarbon distributions of the hot-soak profiles were found to be similar to refueling emissions. The only significant difference in the profiles was in the aromatic content, which may be related to the.
A Novel Design of U-Slotted SIW Based Wideband Antenna

In this paper, we proposed a novel design of U-slotted SIW antenna. Our antenna design is aimed to cover upper K-band and lower Ka-band spectrums, specifically from 24 GHz to 32 GHz. It has a compact square size of 5.2 x 5.2 mm 2 . We use a rectangular truncated corner to optimize the square radiator. The optimized rectangular truncated corner size of 2 x 0.8 mm 2 gives an impedance bandwidth of 7.87 GHz. SIW cavity is constructed by using multiple metallic via-holes which are drilled in a dielectric substrate establishing. Next optimization, applying the U-shaped slot and SIW structure yield a wider impedance bandwidth of 8.89 GHz, there is about 1.02 GHz of impedance bandwidth enhancement. In addition, the SIW structure gives a higher gain of 7.63 dB and decreases the sidelobe level of -12.1 dB. Implementation of the SIW structure significantly decreases the size of antenna while keeping the antenna parameter’s performances.
Control of assimilable organic carbon (AOC) concentrations in a water distribution system

Abstract The aim of this study is to measure the bioavailable organic matter content in water. This study examines the changes in assimilable organic carbon (AOC) concentrations in a traditional water treatment plant in southern Taiwan and its associate water distribution system. The addition of chlorine to raw water is shown to produce an increase in AOC, resulting in waterborne AOC concentrations in excess of 50 μg acetate-C/L in some circumstances. Examination of water distribution networks indicate that AOC values decrease as the distance from the treatment facility increases. The residual chlorine concentrations in the distribution system must be in the range from 0.52 to 0.73 mg/L.
PREPARATION OF A NOVEL HYBRID MONOLITHIC COLUMN BASED ON ATRP OF GMA CATALYZED BY FeCl2/CCl4 AND APPLICATION IN THE SEPARATION OF PROTEINS

In the present study, a novel rod-shape hybrid monolithic column has been prepared by surface-initiated atom transfer radical polymerization. Compared with the traditional monoliths, the monolith could trend to form the 3-dimensional bicontinuous skeleton structure with macroporous, because of low concentration of free radical and the stepwise growth of polymer chains in atom transfer radical polymerization. Through a novel catalyst system of combining iron ferrous chloride and carbon tetrachloride, the monolith was made from Glycidyl methacrylate, Ethylene glycol dimethacrylate, dodecyl alcohol, and methyl alcohol. The monolithic column was characterized by various techniques, such as Scanning electron microscopy and Fourier transform infrared spectroscopy. The monolithic column was used for protein separation and the method reproducibility was tested by evaluating the intra- and inter-day precisions. The results show that the monolith column according to atom transfer radical polymerization exhibits good separation capability through the testing analysis.
Nanometer-sized, divalent-Mn, hydrous silicate domains in geothermal brine precipitates

Abstract X-ray diffraction, infrared spectroscopy, and X-ray absorption (XANES and EXAFS) spectroscopy were combined to characterize poorly crystalline Mn-rich silicate scale deposited from brine at a geothermal field in Indonesia. The precipitate has a vitreous pink-amber appearance, a nearly pure SiO2-MnO-H2O chemical composition, and a bulk Mn/Si atomic ratio of 0.63. X-ray microfluorescence indicated that the sample consists of Mn-free and Mn-containing silica domains, whose Mn/Si ratio (1.2 ± 0.4) ranges between those of 2:1 and 1:1 phyllosilicates. The XRD pattern is characterized by a broad scattering band spanning from ~6 to ~2.5 Å with weak modulations at 5.3, 3.5, and 2.72 Å, and a faint band at 1.605 Å. A surrogate was synthesized in an O2-free atmosphere by mixing and aging at 150 °C an MnCl2 and a sodium meta-silicate solution for 3 hours. Its XRD pattern was similar to the scale sample, but the two reflections at 2.72 and 1.605 Å were enhanced and the former was asymmetrical as in randomly stacked layered compounds. Diffraction data are consistent with a mixture of amorphous silica and a poorly ordered manganoan sheet silicate with a domain size of 40.50 Å for the scale and 50.60 Å for the surrogate material. The divalent oxidation state of manganese was confirmed by XANES spectroscopy, and the presumed existence of trioctahedral [Mn2+]3(O,OH) clusters having a clay-like local structure was corroborated by the existence of a weak vibration band at 600-650 cm-1 in infrared spectra. The connectivity of Mn octahedra was examined using EXAFS spectroscopy by comparing the local structure of Mn in the scale sample and in a large series of Mn compounds having different kinds of Mn octahedra and Si tetrahedra linkages. The manganoan scale has a polyhedral local structure resembling that of sheet silicates, in which metal octahedra are joined along edges and share corners with ditrigonal SiO4 rings. Similar short-range ordering has been described in Fe- and Al- silicate scales, but the Mn-silicate scale has a lower domain size owing to the greater misfit between the lateral dimensions of the Mn and Si sheets. The strain induced by the shrinkage of the Mn sheet to fit the Si sheet(s) is alleviated by the nanometer size of the two-dimensional hydrous silicate domains.
