TinyDroid: A Lightweight and Efficient Model for Android Malware Detection and Classification (2018)

With the popularity of Android applications, Android malware has an exponential growth trend. In order to detect Android malware effectively, this paper proposes a novel lightweight static detection model, TinyDroid , using instruction simplification and machine learning technique. First, a symbol-based simplification method is proposed to abstract the opcode sequence decompiled from Android Dalvik Executable files. Then, N-gram is employed to extract features from the simplified opcode sequence, and a classifier is trained for the malware detection and classification tasks. To improve the efficiency and scalability of the proposed detection model, a compression procedure is also used to reduce features and select exemplars for the malware sample dataset. TinyDroid is compared against the state-of-the-art antivirus tools in real world using Drebin dataset. The experimental results show that TinyDroid can get a higher accuracy rate and lower false alarm rate with satisfied efficiency.

Motion Information Inferring Scheme for Multi-View Video Coding (2008)

This letter proposes a motion information inferring scheme for multi-view video coding motivated by the idea that the aspect of motion vector between the corresponding positions in the neighboring view pair is quite similar. The proposed method infers the motion information from the corresponding macroblock in the neighboring view after RD optimization with the existing prediction modes. This letter presents evaluation showing that the method significantly enhances the efficiency especially at high bit rates.
N-type perylene-based organic semiconductors for functional neural interfacing (2013)

The bioelectrical signalling within neural networks has to be monitored in real-time and localized in space in order to unravel the mechanisms behind pathologies and diseases of the nervous systems. Organic materials have significant potential for bio-functional neural interfacing given that their "soft" nature offers better mechanical compatibility with the nerve tissues than conventional semiconductors, and their flexibility allows realization of the non-planar forms typically required for biomedical implants. The integration of living cells into organic semiconductors is an important step towards the development of bio-organic electronic transducers of cellular activity from neurons. Here, we report on the use and characterization of n-type perylene derivatives as a suitable interface platform for organic neuro-electronic devices. We demonstrate that primary neurons can adhere, grow and differentiate on a suitably engineered perylene-based field-effect transistor platform, while maintaining their firing properties even after a prolonged time of cell-culturing. It is noteworthy that the field-effect transistors preserve their electrical characteristics even after 10 days of incubation in cell culture media. These results validate n-type perylene derivatives as a suitable long-term interface platform for organic neuro-electronic devices, which is particularly relevant in view of the recently reported perylene-based field-effect transistor structure capable of providing bidirectional stimulation and recording of primary neurons.

Techno-economic valuation of mobile communications scenarios (2010)

Valuation of large projects on new communications technologies is a challenging task. Major investments are required to spread out technology and services, the characteristics of which are still largely unknown. A balanced view is needed on capabilities of the technologies, market demand, and relevant value network actors and their economies. In this dissertation, comprehensive techno-economic modelling of these aspects will be introduced for valuation of selected business scenarios. The research framework is mobile data services and business architectures in the advent of new technologies, like UMTS (Universal Mobile Telecommunications System), WLAN (Wireless Local Area Network) and WiMAX (Worldwide Interoperability for Microwave Access). The techno-economic method in this context comprises the modelling of a large set of technology, market and other factors in relation to the business operations of the analysed market actors. The many uncertainties concerning future service innovations and market development set demands on scenario creation and parameter estimation. Traditional techno-economic investment project calculation is not enough. &#13;\n This study gives devices for strategic decision making by analysing three different technology transitions: The modelling of Western-European incumbent operator business starting from the early 2000's indicated that the UMTS deployment should be started without delay to maximise the long-term profits from the acquired licenses, contrary to looking for short-term investment payoffs that was prevalent after the telecommunications downturn. Results also show that the emerging WLAN technology would not become a substitute for UMTS, but the public WLAN will complement the UMTS based business architecture. Modelling of the upcoming mobile WiMAX in comparison to UMTS path indicated that the mobile WiMAX cannot challenge the UMTS, as the latter one offers a better business case for the key actors. In the last transition, techno-economic delta analysis was used to quantify the benefits from the fixed-mobile convergence. &#13;\n The main enhancements to the techno-economic method are first the extensive classification of advanced mobile services and related modelling of service diffusion, usage patterns, capacity requirements and revenues. The second contribution is to improve the analysis of service usage in relation to technology characteristics by integrating an end-user model that gives the demand and revenue potential of each service type, per user segment and utilised technology. A novelty is also the separation of network provisioning and service provisioning part of the business architecture into separate but interlinked models. The fourth contribution to the method is the application of real options method on large communications technology deployment projects, solving option modelling problems due to the complex dependencies of the project value on the investment timing. The introduced method starts from ordinary expected cash flow valuation, but adds to that the option value related to specific flexibility in the project.
LSP Ping/Traceroute for Prefix SID in Presence of Multi-Algorithm/Multi-Topology Networks (2018)

[RFC8287] defines the extensions to MPLS LSP Ping and Traceroute for
Segment Routing IGP-Prefix and IGP-Adjacency Segment Identifier (SIDs)
with an MPLS data plane. The machinery defined in [RFC8287] works well
in single topology, single algorithm deployments where each Prefix SID
is only associated with a single IP prefix. In multi-topology
networks, or networks deploying multiple algorithms for the same IP
Prefix, MPLS echo request needs to carry additional information in the
Target FEC Stack sub-TLVs to properly validate IGP Prefix SID. This
document updates [RFC8287] by modifying IPv4 and IPv6 IGP-Prefix
Segment ID FEC sub-TLVs to also include algorithm identification while
maintaining backwards compatibility. This document also introduces new
Target FEC Stack sub-TLVs for Prefix SID validation in multi-topology
networks.
ARAPReg: An As-Rigid-As Possible Regularization Loss for Learning Deformable Shape Generators (2021)

This paper introduces an unsupervised loss for training parametric deformation shape generators. The key idea is to enforce the preservation of local rigidity among the generated shapes. Our approach builds on an approximation of the as-rigid-as possible (or ARAP) deformation energy. We show how to develop the unsupervised loss via a spectral decomposition of the Hessian of the ARAP energy. Our loss nicely decouples pose and shape variations through a robust norm. The loss admits simple closed-form expressions. It is easy to train and can be plugged into any standard generation models, e.g., variational auto-encoder (VAE) and auto-decoder (AD). Experimental results show that our approach outperforms existing shape generation approaches considerably on public benchmark datasets of various shape categories such as human, animal and bone. Our code and data are available at https://github.com/GitBoSun/ARAPReg.
Blueberry latent virus in highbush blueberry (Vaccinium corymbosum L.) in Bosnia and Herzegovina (2022)

A small-scale survey for blueberry viruses in Bosnia and Herzegovina was performed in 2018. A total of 20 samples from three locations were collected and analyzed for the presence of 11 viruses. ELISA assays were performed for blueberry scorch virus, blueberry shock virus, blueberry shoestring virus, blueberry leaf mottle virus, tobacco ringspot virus, and tomato ring spot virus. The samples were tested for blueberry red ringspot virus by PCR, and blueberry fruit drop associated virus, blueberry latent virus, blueberry mosaic associated virus, blueberry necrotic ring blotch virus, blueberry virus A, and blueberry leaf mottle virus by RT-PCR. The analyses confirmed the presence of BlLV in eight samples with no other virus detected in any of the samples.
Functional Relevance of the IL-23–IL-17 Axis in Lungs In Vivo (2006)

It is known that interleukin (IL)-23, an IL-12-family cytokine, can be released by certain antigen-presenting cells in response to bacterial pathogens. Recent in vitro studies indicate that this cytokine stimulates a unique subset of CD4 cells, the T helper cell (Th)17 subset, to produce and release the proinflammatory cytokine IL-17. However, it has not been known whether this is an action of IL-23 per se that has bearing for the early innate response in lungs in vivo and whether there is an IL-23-responsive population of IL-17-producing CD4 cells in the bronchoalveolar space. We now present evidence that IL-23 can be involved in the early innate response to both gram-negative and gram-positive bacterial products in the lungs: Recombinant IL-23 protein per se accumulates inflammatory cells in the bronchoalveolar space in part via endogenous production of IL-17, and this IL-17 production occurs locally in IL-23-responsive CD4 cells. This IL-17 response to IL-23 occurs without any pronounced impact on Th1/Th2 polarization. Moreover, recombinant IL-23 protein increases the local MMP-9 activity, which is generated by neutrophils mainly. CD4 cells in the lungs may thus respond to IL-23 from antigen-presenting cells exposed to gram-negative and gram-positive pathogens and thereby reinforce the early innate response. These findings support that IL-23 and IL-17 form a functionally relevant "immunological axis" in the lungs in vivo.
Oxygen implants using water vapor as source feed gas in high and medium current implanters (2002)

Refractory metals used in ion sources (such as tungsten) will oxidize using ordinary oxygen bearing gases for oxygen implantation. By comparing the free energy of formation of different feed gases with tungsten oxide it was found that for temperatures between 960°C and 3300°C tungsten will preferably not oxidize in a water vapor environment. For high current implanters the tungsten arc chamber walls and filaments operate in this temperature range, making water a viable feed gas for O <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">+</sup> implants. Stable beam currents of up to 7.5 mA have been achieved.
Generalized information fusion and visualization using spatial voting and data modeling (2013)

We present a novel and innovative information fusion and visualization framework for multi-source intelligence (multiINT) data using Spatial Voting (SV) and Data Modeling. We describe how different sources of information can be converted into numerical form for further processing downstream, followed by a short description of how this information can be fused using the SV grid. As an illustrative example, we show the modeling of cyberspace as cyber layers for the purpose of tracking cyber personas. Finally we describe a path ahead for creating interactive agile networks through defender customized Cyber-cubes for network configuration and attack visualization.
Fabrication and performance of high-frequency composite transducers with triangular-pillar geometry (2009)

A single-element, 40-MHz, 3-mm diameter transducer was fabricated with a geometric focus at 9 mm. The transducer was based on a piezo-composite substrate with triangular-shaped composite pillars. The 2-way bandwidth of 50% and impedance magnitude were in agreement with that predicted using finite-element modeling. A one-way radiation pattern was collected using a needle hydrophone. The one-way -3 dB beamwidth at the geometric focus was measured to be 120 microm and the -3 dB depth of field was 2.5 mm. This is in good agreement with the theoretical predictions of 112.5 microm and 2.4 mm. The triangular-pillar composite transducer was then compared with a transducer with square composite pillars with similar volume fraction of active ceramic. A 9.5 dB reduction in the amplitude of the secondary resonance was found for the triangular-pillar composite as well as a 30% gain in the 2-way pulse bandwidth. A 256-element 30-MHz linear array was fabricated as a preliminary investigation into the use of the triangular pillar as the substrate in a high-frequency linear array transducer. In vivo images were generated with both the single-element and linear-array transducers.
Reciprocal regulation of GAS5 lncRNA levels and mTOR inhibitor action in prostate cancer cells (2015)

mTOR inhibition enhances GAS5 transcript levels in certain prostate cancer cell lines. This selectivity is likely to be related to endogenous GAS5 expression levels, since GAS5 lncRNA is itself required for mTOR inhibitor action in prostate cancer cells.
Protection by exogenous pyruvate through a mechanism related to monocarboxylate transporters against cell death induced by hydrogen peroxide in cultured rat cortical neurons (2005)

In cortical neurons cultured for 3 or 9 days in vitro (DIV), exposure to hydrogen peroxide (H(2)O(2)) led to a marked decrease in cell viability in a concentration-dependent manner at a concentration range of 10 microm to 1 mm irrespective of the duration between 6 and 24 h. However, H(2)O(2) was more potent in decreasing cellular viability in cortical neurons cultured for 9 DIV than in those for 3 DIV. Pyruvate was effective in preventing the neuronal cell death at 1 mm even when added 1-3 h after the addition of H(2)O(2). Semi-quantitative RT-PCR and western blotting analyses revealed significantly higher expression of both mRNA and protein for a particular monocarboxylate transporter (MCT) in neurons cultured for 9 DIV than in those for 3 DIV. A specific inhibitor of MCT significantly attenuated the neuroprotection by pyruvate in neurons cultured for 9 DIV, without markedly affecting that in neurons cultured for 3 DIV. These results suggest that vulnerability to H(2)O(2) may at least in part involve expression of particular MCT isoforms responsible for the bi-directional transport of pyruvate across cell surfaces in cultured rat cortical neurons.
A New Method for the Synthesis of 2-Hydroxy-3-nitro-1,4-naphthoquinones:  Application to Regiospecific Preparation of Unsymmetrical Nitrobiquinones (2006)

Novel 2-hydroxy-3-nitro-1,4-naphthoquinones were synthesized by an improved method utilizing nitronium tetrafluoroborate in high yields. A subsequent conversion to 2-chloro-3-nitro-1,4-naphthoquinones and a substitution of the chlorine by hydroxyquinone anions yielded 3-nitro-2,2'-binaphthoquinones with a complete regiocontrol.
Continuous Culture Studies on the Biosynthesis of Alkaline Protease, Neutral Protease and -Amylase by Bacillus subtilis NRRL-B3411 (1972)

SUMMARY: The amounts of three catabolite repressible enzymes, alkaline protease, neutral protease and α-amylase, produced by Bacillus subtilis NRRL-B3411 growing in a chemostat, depended on the growth-limiting substrate. Limiting growth with glucose was advantageous for α-amylase synthesis while nitrogen-limited growth was advantageous for synthesis of the two proteases. Under the conditions used, continuous cultures were unsuitable for large-scale production of the three enzymes since spontaneous mutations to less productive strains occurred in the long term.
MOSC domains: ancient, predicted sulfur-carrier domains, present in diverse metalâsulfur cluster biosynthesis proteins including Molybdenum cofactor sulfurases (2002)

Using computational analysis, a novel superfamily of beta-strand-rich domains was identified in the Molybdenum cofactor sulfurase and several other proteins from both prokaryotes and eukaryotes. These MOSC domains contain an absolutely conserved cysteine and occur either as stand-alone forms such as the bacterial YiiM proteins, or fused to other domains such as a NifS-like catalytic domain in Molybdenum cofactor sulfurase. The MOSC domain is predicted to be a sulfur-carrier domain that receives sulfur abstracted by the pyridoxal phosphate-dependent NifS-like enzymes, on its conserved cysteine, and delivers it for the formation of diverse sulfur-metal clusters. The identification of this domain may clarify the mechanism of biogenesis of various metallo-enzymes including Molybdenum cofactor-containing enzymes that are compromised in human type II xanthinuria.
GNSS Independent Position Fixing using Multiple Navigational Features Registration (2022)

Safe navigation at sea depends on reliable position information. The easy to use and readily available navigation satellite systems are providing round the clock position information for seafarers, but denial of these services by jamming or spoofing techniques have become frequent, and other means are needed to validate critical navigation information. This paper revisits traditional methods to estimate position and heading of a vessel and offers a framework for computerized calculation of these basic observables without the use of radio-borne external information. Using radar and sea chart information, the paper investigates the quality of navigation information based on observed location of beacons, landmarks, coastlines and buoys. The paper demonstrates convincing accuracy in both position and heading estimation.
A Dual Waveband Imaging Radiometer (1986)

This paper describes a Dual Waveband Imaging Radiometer (DUWIR) which GEC Avionics have developed for RSRE Malvern and which has now been put into production. This calibrated imager basically provides synchronous, simultaneous imagery in both infrared wavebands, that is pixel by pixel overlay, from a single optical channel. It combines current generation modular FLIR performance with the necessary internal calibrated references to enable it to function as a radiometer, measuring apparent temperatures in both bands. It also has all the necessary radiometric and system status information displayed in graphic form, overlaid on video to permit ease of subsequent analysis of the imagery. It is based on the Class II, UK Thermal Imaging Common Module (TICM) modules (Figure 1), which comprise the six processing cards and power supply module, the scanner module, the detector lens module, the head amplifier module and the motor drive module which form the basis of the UK high performance, indirect view, modular thermal imager. Selected systems contractors can configure a complete imaging system from these modules by adding a suitable housing, telescope, display, controls and cryogen supply. Note that as the Class II system is intrinsically TV compatible, scanning one TR line for every TV line (including interlaced fields) it does not require any additional scan convertor or interpolator.

Inhibitory Effect of Mitoxantrone on Collagen Synthesis in Dermal Fibroblasts (2022)

These results suggest that mitoxantrone reduces collagen synthesis by inhibiting TGF-β/SMAD signaling and LARP6 expression in fibroblasts, which can be developed as a therapeutic agent for diseases caused by collagen hypersynthesis.
Stereotactic Aspiration and Fibrinolysis of Spontaneous Supratentorial Intracerebral Hematomas versus Conservative Treatment: A Matched-Pair Study (2003)

These results indicate that patients do not benefit from stereotactic aspiration and fibrinolysis of putamenal hematomas. For a final treatment recommendation a prospective randomised trial is required.
A little to a lot or a lot to a little: is NTCP always minimized in multiport therapy? (1998)

In contrast to what is commonly believed, this study suggests that for at least two normal tissues, namely lung and kidney, there may be situations where "a lot to a little" (i.e., fewer treatment ports) will result in higher tumor control probability and better treatment plan than "a little to a lot" (i.e., multifield treatment). This finding, which is independent of the binomial or probit models used here, depends only on the accuracy of the empirical NTCP data. It is also interesting to note that: a) lung and kidney are commonly classified as parallel tissues, while the others have more of a serial architecture; and b) the choice of the NTCP model can have a profound impact on treatment planning decisions.
