Behavioral Entropy Towards Detection of Metamorphic Malwares (2019)

Recent metamorphic malware detection methods based on statistical analysis of malware code and measuring similarity between codes are by far more superior compared with signature-based detection methods; yet, lacking against code obfuscation methods including insertion of garbage codes similar to benign files and replacing instructions with equivalent instructions. This paper proposes a method on improved detection of metamorphic malwares based on activity and behavior analysis of executable files. The process involves two stages: initially, behavior of the file is analyzed during runtime and the behavioral pattern is obtained; then, in the second stage, behavioral patterns of the malware files are compared with the sample file in order to determine the level of similarity. The stage on analyzing behavior of the file is accomplished in a monitored environment and then malicious behavioral features of the file are extracted. The second stage involves determining level of similarity between malwares registered into the database in the first stage and the sample files. The obtained experimental results show that the proposed method, by determining the similarity level of behavioral patterns, significantly improves detection of metamorphic malwares and along with no false positives.
Amorphous Built-in-Field Effect Photoreceptors (1982)

Thin-film photodiodes with the graded-composition structures of amorphous Se–As–Te have been developed. The physical mechanism of the buit-in-field effect in these highly resistive photodiodes has been clarified. In order to realize complicated composition distributions, multi-layer evaporation technology has also been developed. The physical properties of multi-layered films and those of the uniform amorphous film have been compared, and it has been shown that a multi-layered film of 1 nm periodicity can be regarded as an almost uniform amorphous material. Built-in-field effect photoreceptors can be utilized not only for TV pickup tubes but also for highly sensitive xerographic plate and other solid-state sensors.
Enhanced material defect imaging with a radio-frequency atomic magnetometer (2019)

Imaging of structural defects in a material can be realized with a radio-frequency atomic magnetometer by monitoring the material’s response to a radio-frequency excitation field. We demonstrate two measurement configurations that enable the increase of the amplitude and phase contrast in images that represent a structural defect in electrically conductive and magnetically permeable samples. Both concepts involve the elimination of the excitation field component, orthogonal to the sample surface, from the atomic magnetometer signal. The first method relies on the implementation of a set of coils that directly compensates the excitation field component in the magnetometer signal. The second takes advantage of the fact that the radio-frequency magnetometer is not sensitive to the magnetic field oscillating along one of its axes. Results from simple modelling confirm the experimental observation and are discussed in detail.
Anomalous splitting in microwave mode-beating spectra of semiconductor ring lasers (2005)

Mode-beating spectra are investigated in long-perimeter (1.028 cm) monolithically integrated multiple-quantum-well semiconductor ring lasers. The beating line near 8 GHz is found to be split into two components. With increasing pumping current, a normal component shifts to lower frequencies, while an anomalous higher-frequency component shifts in the opposite direction. It is suggested the anomalous blue-shifting line results from power-induced perturbation of the refractive index in the vicinity of a strong mode.
Decay dynamics of the positively charged exciton in a single charge tunable self-assembled quantum dot (2006)

We report on the decay dynamics of positively charged excitons confined to single InAs quantum dots embedded in an n-type field-effect structure. The positively charged exciton’s dynamics are found to be strongly dependent on device dimensions. With a large (small) dot capping layer the decay is dominated by hole tunneling (radiative recombination). The hole tunneling is successfully modeled with a WKB-like zero-dimensional to three-dimensional tunneling approximation. Hole tunneling is not observed in the dynamics of the neutral exciton negatively charged exciton, or biexciton, an effect we attribute to an increase in barrier height through the interdot Coulomb interactions.
Modeling Coordination Costs Due to Time Separation in Global Software Teams (2003)

Research to date has not attempted to model coordination in global software teams. We formulate a preliminary collaboration model for a dyad to help us understand the consequences of time separation. We first describe the model and its theoretical foundations and we then evaluate the model by simulating several thousand observations and running regression models to inspect the effect of different variables on coordination costs. We then make suggestions for further extension of the model to include more complex scenarios with multiple collaborators and fewer assumptions. Our evaluation shows that the consequences of time separation are complex and that we need to understand them well before we can make claims about coordination outcomes in larger software teams that are separated by time zones.
When 2.5D is not enough: Simultaneous reconstruction, segmentation and recognition on dense SLAM (2016)

While the main trend of 3D object recognition has been to infer object detection from single views of the scene - i.e., 2.5D data - this work explores the direction on performing object recognition on 3D data that is reconstructed from multiple viewpoints, under the conjecture that such data can improve the robustness of an object recognition system. To achieve this goal, we propose a framework whichreal-time segmentation is able (i) to carry out incremental real-time segmentation of a 3D scene while being reconstructed via Simultaneous Localization And Mapping (SLAM), and (ii) to simultaneously and incrementally carry out 3D object recognition and pose estimation on the reconstructed and segmented 3D representations. Experimental results demonstrate the advantages of our approach with respect to traditional single view-based object recognition and pose estimation approaches, as well as its usefulness in robotic perception and augmented reality applications.
Sales Forecast for Amazon Sales with Time Series Modeling (2020)

Accurate sales prediction plays an important role in reducing costs and improving customer service levels, especially for B2C(Business to consumer) e-commerce. This paper attempts to forecast future sales at Amazon.com, Inc. based on historical sales data. Firstly, it proposes three possible forecasting approaches according to the historical data pattern, that is Holt-Winters exponential smoothing, neural network auto regression model and ARIMA(Autoregressive integrated moving average). Secondly, it specifies certain accuracy measures using which well determine the suitability of the forecast methods on the available sales data. Finally the three methods will be implemented to forecast Amazons quarterly sales in 2019. The results can help Amazon well manage its future operations.
Authentication mechanism over the integrated UMTS network and WLAN platform using the cross-layer bootstrap (2007)

The 3G mobile data network provides always-on and ubiquitous connectivity for subscribers. Although the service coverage area in wireless local area network (WLAN) is much smaller than that in a 3G mobile data network, the data transmission rate in WLAN can be from 2 to 54 Mbps, which is much faster than 3G mobile network. Obviously, the relationship between the 3G mobile data network and WLAN is complementary in terms of service coverage and data transmission rate. Therefore integration of 3G mobile network and WLAN can offer subscribers higher speed wireless service in hot spots and ubiquitous connectivity in 3G mobile data network. An authentication mechanism over the loose coupled integration mechanism using a cross-layer bootstrap is proposed. The benefits of the proposed mechanism are (a) integrating Universal Mobile Telecommunication System network and WLAN using the existing protocols defined in 3GPP, IETF and IEEE 802.11i, (b) the use of the Extension Authentication Protocol authentication method is flexible, (c) reduction of the authentication signalling when a subscriber roams from one access point (AP) to another AP and (d) user identity privacy protection.
Atypical Protein Kinase Cι (PKCι) Promotes Metastasis of Esophageal Squamous Cell Carcinoma by Enhancing Resistance to Anoikis via PKCι-SKP2-AKT Pathway (2011)

Protein kinase Cι (PKCι) is an atypical PKC isoform and participates in multiple aspects of the transformed phenotype in human cancer cells. We previously reported that frequent amplification and overexpression of PKCι were correlated with lymph node metastasis in primary esophageal squamous cell carcinomas (ESCC). In the present study, short interfering RNA-mediated silencing of PKCι revealed that this enzyme was required for cell migration, invasion, and resistance to anoikis. In vivo experiments showed that PKCι suppression decreased tumor growth in esophageal cancer xenografts and lung metastases in nude mice. At the molecular level, knockdown of PKCι in suspended ESCC cells caused a decrease in S-phase kinase-associated protein 2 (SKP2) that had been reported to promote resistance to anoikis via the PI3K/AKT pathway. AKT phosphorylation was abolished after PKCι suppression, but AKT activation could be refreshed by PKCι upregulation, suggesting that PKCι enhanced cell resistance to anoikis via the PKCι-SKP2-PI3K/AKT pathway. Addition of the proteasome inhibitor MG132 prevented the decrease of SKP2 in PKCι silenced cells, and polyubiquitin-SKP2 was elevated after PKCι depletion, showing that PKCι might regulate the expression of SKP2 through the ubiquitin-proteasome pathway in suspended cells. Furthermore, overexpression of SKP2 in PKCι-downregulated cells restored cell resistance to anoikis. Most importantly, PKCι expression significantly correlated with SKP2 in 133 ESCC tissues (P = 0.031). Taken together, our data show that PKCι promotes tumorigenicity and metastasis of human esophageal cancer and that SKP2 is a candidate downstream effector of PKCι signaling in ESCC.
An iterative fullwave simulation approach to multiple scattering in media with randomly distributed microbubbles (2017)

Ultrasound contrast agents (UCA), such as microbubbles, enhance the scattering properties of blood, which is otherwise hypoechoic. The multiple scattering interactions of the acoustic field with UCA are poorly understood due to the complexity of the multiple scattering theories and the nonlinear microbubble response. The majority of bubble models describe the behavior of UCA as single, isolated microbubbles suspended in infinite medium. Multiple scattering models such as the independent scattering approximation can approximate phase velocity and attenuation for low scatterer volume fractions. However, all current models and simulation approaches only describe multiple scattering and nonlinear bubble dynamics separately. Here we present an approach that combines two existing models: (1) a full-wave model that describes nonlinear propagation and scattering interactions in a heterogeneous attenuating medium and (2) a Paul-Sarkar model that describes the nonlinear interactions between an acoustic field and microbubbles. These two models were solved numerically and combined with an iterative approach. The convergence of this combined model was explored in silico for 0.5 × 10<sup>6</sup> microbubbles ml<sup>-1</sup>, 1% and 2% bubble concentration by volume. The backscattering predicted by our modeling approach was verified experimentally with water tank measurements performed with a 128-element linear array transducer. An excellent agreement in terms of the fundamental and harmonic acoustic fields is shown. Additionally, our model correctly predicts the phase velocity and attenuation measured using through transmission and predicted by the independent scattering approximation.
Weisfeiler-Lehman Neural Machine for Link Prediction (2017)

In this paper, we propose a next-generation link prediction method, Weisfeiler-Lehman Neural Machine (WLNM), which learns topological features in the form of graph patterns that promote the formation of links. WLNM has unmatched advantages including higher performance than state-of-the-art methods and universal applicability over various kinds of networks. WLNM extracts an enclosing subgraph of each target link and encodes the subgraph as an adjacency matrix. The key novelty of the encoding comes from a fast hashing-based Weisfeiler-Lehman (WL) algorithm that labels the vertices according to their structural roles in the subgraph while preserving the subgraph's intrinsic directionality. After that, a neural network is trained on these adjacency matrices to learn a predictive model. Compared with traditional link prediction methods, WLNM does not assume a particular link formation mechanism (such as common neighbors), but learns this mechanism from the graph itself. We conduct comprehensive experiments to show that WLNM not only outperforms a great number of state-of-the-art link prediction methods, but also consistently performs well across networks with different characteristics.

FLAVOR AND QUALITY CHANGES IN SWEET ONIONS DURING STORAGE AT ROOM TEMPERATURE (1994)

ABSTRACT Flavor and quality parameters of onions (Allium cepa ‘Walla Walla Sweet’) were monitored for up to 7 weeks following harvest. Shelf‐life of bulbs harvested earlier in the season was shorter than that of onions harvested 3 weeks later. Soluble solids of inner scales and average pyruvate, 3,4‐dimethyl thiophene and disulfides content increased during the 4 week shelf‐life at 22C of the onions harvested in June. These increases resulted in the final contents to be comparable to those of onions harvested on July 2, 1992, which were relatively stable. The pyruvate concentration was comparable to that of a mild, nonpungent onion. Correlations between pyruvate, thiophene and soluble solids were not significant. The relationship between 3,4‐dimethyl thiophene, disulfides and onion flavor is discussed.
Enhancement of the photoelectric performance of dye-sensitized solar cells using Ag-doped TiO2 nanofibers in a TiO2 film as electrode (2012)

For high solar conversion efficiency of dye-sensitized solar cells [DSSCs], TiO2 nanofiber [TN] and Ag-doped TiO2 nanofiber [ATN] have been extended to be included in TiO2 films to increase the amount of dye loading for a higher short-circuit current. The ATN was used on affected DSSCs to increase the open circuit voltage. This process had enhanced the exit in dye molecules which were rapidly split into electrons, and the DSSCs with ATN stop the recombination of the electronic process. The conversion efficiency of TiO2 photoelectrode-based DSSCs was 4.74%; it was increased to 6.13% after adding 5 wt.% ATN into TiO2 films. The electron lifetime of DSSCs with ATN increased from 0.29 to 0.34 s and that electron recombination was reduced.

Thermal Impact of an Active 3-D Microelectrode Array Implanted in the Brain (2007)

A chronically implantable, wireless neural interface device will require integrating electronic circuitry with the interfacing microelectrodes in order to eliminate wired connections. Since the integrated circuit (IC) dissipates a certain amount of power, it will raise the temperature in surrounding tissues where it is implanted. In this paper, the thermal influence of the integrated 3-D Utah electrode array (UEA) device implanted in the brain was investigated by numerical simulation using finite element analysis (FEA) and by experimental measurement in vitro as well as in vivo. The numerically calculated and experimentally measured temperature increases due to the UEA implantation were in good agreement. The experimentally validated numerical model predicted that the temperature increases linearly with power dissipation through the UEA, with a slope of 0.029 degree C/mW over the power dissipation levels expected to be used. The influences of blood perfusion, brain metabolism, and UEA geometry on tissue heating were also investigated using the numerical model.

Instability of semiconductor lasers due to optical feedback from distant reflectors (1986)

We explain an istability occurring in continuously operating lasers due to moderate feedback from distant reflectors. This instability occurs despite the fact that the laser is stable with respect to small deviations from steady-state operation. It is the result of finite phase and carrier number changes caused by fluctuations in spontaneous emission. We predict several properties that agree with recent experimental observations: 1) the instability only occurs when the laser reaches a steady state that maximizes coherent feedback and laser light intensity; 2) the instability vanishes at strong feedback levels; and 3) at moderate feedback levels, the laser will be nearly stable at threshold, but unstable when operated well above threshold. The latter behavior results in a nonlinear "kinked" shape in the light versus current relation.
MMOD-induced structural changes of hydroxylase in soluble methane monooxygenase (2019)

Soluble methane monooxygenase in methanotrophs converts methane to methanol under ambient conditions. The maximum catalytic activity of hydroxylase (MMOH) is achieved through the interplay of its regulatory protein (MMOB) and reductase. An additional auxiliary protein, MMOD, functions as an inhibitor of MMOH; however, its inhibitory mechanism remains unknown. Here, we report the crystal structure of the MMOH-MMOD complex from <i>Methylosinus sporium</i> strain 5 (2.6 Å). Its structure illustrates that MMOD associates with the canyon region of MMOH where MMOB binds. Although MMOD and MMOB recognize the same binding site, each binding component triggers different conformational changes toward MMOH, which then respectively lead to the inhibition and activation of MMOH. Particularly, MMOD binding perturbs the di-iron geometry by inducing two major MMOH conformational changes, i.e., MMOH β subunit disorganization and subsequent His<sup>147</sup> dissociation with Fe1 coordination. Furthermore, 1,6-hexanediol, a mimic of the products of sMMO, reveals the substrate access route.
Update on Antiarrhythmic Therapy: Dofetilide (2022)

Dofetilide is one of the several novel methanesulfonamide compounds that selectively inhibits the rapid component of the delayed rectifier potassium current, IKr, thus prolonging the effective refractory period (ERP) and the action potential duration (APD) in both the atria and the ventricles. It has no effects on sodium and calcium channels, and therefore, has minimal effects on myocardial conduction velocity. Dofetilide can be administered either orally or intravenously, and has a rapid onset of action. It was recently approved in the United States for the maintenance and conversion of normal sinus rhythm in patients with atrial fibrillation (AF).
