Effective Charge Determination of Dendrigraft Poly-L-lysine by Capillary Isotachophoresis

In this work, capillary isotachophoresis (ITP) was used to determine the effective charge of the first five generations of dendrigraft poly-l-lysines. This approach, which is based on the linear dependence of ITP zone length of the solute on its concentration and effective charge, offers a simple and straightforward method for effective charge determination. The cationic ITP system employed in this work yields good linearity, repeatability and sharp zones. The value of effective charge number per one lysine residue obtained for long linear poly-l-lysine is in a good agreement with the Manning theoretical value (0.5). Results obtained for dendrigraft poly-l-lysines show a dramatic decrease in the effective charge number per lysine residue with increasing generation number, from 0.84 for short oligolysines (generation 1) down to 0.08 for the fifth generation. This decrease in effective charge is due to the proximity of charged groups in the dendrigraft structure of higher generation number.
A Commercial Imaging and Robotics System for Satellite Space Servicing

Satellite rendezvous-and-capture is a need in the Low-Earth-Orbit (LEO) environment to reduce risk of high value assets colliding with debris. This paper presents a prototype capture system based on an integrated imaging and robotic control solution using commercial off-theshelf hardware and open source software. For the imaging system, a Microsoft Kinect V2 is used to collect two and three dimensional images of objects within its field of view and generate location and orientation data of these objects. A seven degree-of-freedom CrustCrawler Robotics modular robotic arm is used to capture the object while accounting for collision avoidance. The Robotics Operating System (ROS) provides the framework to conduct path planning, actuator control execution, and interfaces for the image processing software compatible with the Microsoft Kinect V2. This prototype system operation is demonstrated by identifying and capturing satellite features on a spacecraft model which emulates common components on LEO spacecraft. Two-dimensional color image analysis, and three-dimensional geometric fitting are used to determine the capture location and orientation of the features. This data is then sent to the control software that will determine an optimal path to then execute the motion and capture the satellite.
Fast Online Trajectory Optimization for the Bipedal Robot Cassie

We apply fast online trajectory optimization for multi-step motion planning to Cassie, a bipedal robot designed to exploit natural spring-mass locomotion dynamics using lightweight, compliant legs. Our motion planning formulation simultaneously optimizes over center of mass motion, footholds, and center of pressure for a simplified model that combines transverse linear inverted pendulum and vertical spring dynamics. A vertex-based representation of the support area combined with this simplified dynamic model that allows closed form integration leads to a fast nonlinear programming problem formulation. This optimization problem is continuously solved online in a model predictive control approach. The output of the reduced-order planner is fed into a quadratic programming based operational space controller for execution on the full-order system. We present simulation results showing the performance and robustness to disturbances of the planning and control framework. Preliminary results on the physical robot show functionality of the operational space control system, with integration of the trajectory planner a work in progress.
Modelling of contaminant migration in unsaturated soils

Laboratory studies are useful for understanding the behaviour of chemical contaminants in soil, although such investigations do not always relate directly to field conditions. This paper reports an application of a model in order to investigate the migration of nitrates through the soil. The model calibration was carried out using the experimental data obtained from two different soil samples collected in the countryside of Catania (Italy). The device used for laboratory scale study was a permeameter loaded with the soil samples; acqueous solutions containing different percentage of nitrate were used as chemical contaminant. Two software products, SEEP/W and CTRAN/W, are used in tandem to analyze the contaminant transport for unsaturated conditions: SEEP/W computes the water flow velocity, volumetric water content, and water flux; CTRAN/W uses these parameters to compute the contaminant migration. Unsaturated zone models are useful tools in predicting the effects of measures and can be used to optimise agricultural practice aiming to minimise the impact on the environment.
Not stealing from the treasure chest (or just a bit): Analyses on plant derived writing supports and non-invasive DNA sampling

Written communication plays a crucial role in the history of modern civilizations as manuscripts do not only exist contemporarily, but are passed on to subsequent generations. Besides a document’s content, information is stored in the materials used for its production. Analyses of the composition allow, for example, identifying the biological origins of materials, dating, and help to understand degradation patterns. A combination of microscopic and DNA approaches was applied in order to analyze various plant derived writing sheets. Given their diversity and abundance in museum collections, plant based writing supports are yet an underexplored target for DNA studies. DNA retrieval of paper is low compared to raw paper plant material, which is likely due to the loss of organic components during paper production. Optimizing DNA extraction for each respective material drastically increased DNA recovery. Finally, we present a non-invasive DNA sampling method that utilizes nylon membranes, commonly used for bacterial DNA sampling and that is applicable to delicate material. Although bacterial infestation was visible on one sample, as indicated by scanning electron microscopy, endogenous DNA was retrieved. The results presented here are promising as they extend the scope of sources for DNA analyses by demonstrating that DNA molecules can be retrieved from a variety of plant derived writing supports. In future, such analyses can help to explore the biological diversity not only of plants and of additives utilized for producing writing supports, but also of the plenty products made from paper.
Automatic Extraction of Access Control Policies from Natural Language Documents

A fundamental management responsibility is securing information systems. Almost all applications that deal with safety, privacy, or defense include some form of access control. There are a plethora of access control models in the information security realm such as role-based access control and attribute-based access control. However, the initial development of access control policies (ACPs) can be very challenging. Most organizations have high-level requirement specifications that include a set of ACPs, which describe allowable operations of the system. It is time consuming and error-prone to manually sift through these documents and extract ACPs. In this paper, we propose a new framework towards extracting ACPs from unrestricted natural language documents using semantic role labeling (SRL). We were able to correctly identify ACP elements with an average <inline-formula><tex-math notation="LaTeX">$F_1$</tex-math><alternatives><mml:math><mml:msub><mml:mi>F</mml:mi><mml:mn>1</mml:mn></mml:msub></mml:math><inline-graphic xlink:href="narouei-ieq1-2818708.gif"/></alternatives></inline-formula> score of 75 percent, which bested the previous work by 15 percent. Furthermore, as SRL tools are often trained on publicly available corpora such as Wall Street Journal, we investigated the idea of improving SRL performance using domain-related knowledge. We utilized domain adaptation and semi-supervised learning techniques and were able to improve the SRL performance by 2 percent using only a small amount of access control data.
A Mutual Information Based Adaptive Windowing of Informative EEG for Emotion Recognition

Emotion recognition using brain wave signals involves using high dimensional electroencephalogram (EEG) data. In this paper, a window selection method based on mutual information is introduced to select an appropriate signal window to reduce the length of the signals. The motivation of the windowing method comes from EEG emotion recognition being computationally costly and the data having low signal-to-noise ratio. The aim of the windowing method is to find a reduced signal where the emotions are strongest. In this paper, it is suggested, that using only the signal section which best describes emotions improves the classification of emotions. This is achieved by iteratively comparing different-length EEG signals at different time locations using the mutual information between the reduced signal and emotion labels as criterion. The reduced signal with the highest mutual information is used for extracting the features for emotion classification. In addition, a viable framework for emotion recognition is introduced. Experimental results on publicly available datasets, DEAP and MAHNOB-HCI, show significant improvement in emotion recognition accuracy.
D MAPPING BY CONTINUOUS-TIME SLAM

This paper shows how to use the result of Google’s SLAM solution, called Cartographer, to bootstrap our continuous-time SLAM algorithm. The presented approach optimizes the consistency of the global point cloud, and thus improves on Google’s results. We use the algorithms and data from Google as input for our continuous-time SLAM software. We also successfully applied our software to a similar backpack system which delivers consistent 3D point clouds even in absence of an IMU.
First–Principle Calculation of the Electronic and Optical Properties of Nanolayered ZnO Polymorphs by PBE and mBJ Density Functionals

(Received 8 Sep. 2017; Revised 16 Oct. 2017; Accepted 21 Nov. 2017; Published 15 Dec. 2017) Abstract: First principle calculations of nanolayered ZnO polymorphs (Wurzite–, Zinc blende–, Rocksalt–structures) in the scheme of density functional theory were performed with the help of full potential linear augmented plane wave (FP-LAPW) method. The exchange correlation potential is described by generalized gradient approximation as proposed by Perdew–Burke–Ernzrhof (GGA–PBE) and modified Becke–Johnson (mBJ) approximation. The electronic behavior and the optical properties of the structures are investigated and compared to experimental data, where available. The electronic structure of w–ZnO and z–ZnO revealed a 3.01 eV and 2.59 eV direct energy gap in (Γ→Γ) direction by applying mBJ potential. In contrast to w– and z–ZnO the electronic structure of r–ZnO shows an indirect 2.81 eV energy gap in (Γ→L) direction. Reflectivity, transmittance and refractive index spectra for three nano layered of ZnO phases in Uv – visible region have been calculated. The electron effective mass values at the bottom of conduction band were evaluated for the three geometries.
Molecular attributes and apoptosis-inducing activities of a putative serine protease isolated from Tiger Milk mushroom (Lignosus rhinocerus) sclerotium against breast cancer cells in vitro

Background The highly valued medicinal tiger milk mushroom (also known as Lignosus rhinocerus) has the ability to cure numerous ailments. Its anticancer activities are well explored, and recently a partially purified cytotoxic protein fraction termed F5 from the mushroom’s sclerotial cold water extract consisting mainly of fungal serine proteases was found to exhibit potent selective cytotoxicity against a human breast adenocarcinoma cell line (MCF7) with IC50 value of 3.00 μg/ml. However, characterization of its cell death-inducing activity has yet to be established. Methods The mechanism involved in the cytotoxic activities of F5 against MCF7 cells was elucidated by flow cytometry-based apoptosis detection, caspases activity measurement, and expression profiling of apoptosis markers by western blotting. Molecular attributes of F5 were further mined from L. rhinocerus’s published genome and transcriptome for future exploration. Results and Discussion Apoptosis induction in MCF7 cells by F5 may involve a cross-talk between the extrinsic and intrinsic apoptotic pathways with upregulation of caspase-8 and -9 activities and a marked decrease of Bcl-2. On the other hand, the levels of pro-apoptotic Bax, BID, and cleaved BID were increased accompanied by observable actin cleavage. At gene level, F5 composed of three predicted non-synonymous single nucleotide polymorphisms (T > C) and an alternative 5′ splice site. Conclusions Findings from this study provide an advanced framework for further investigations on cancer therapeutics development from L. rhinocerus.

General relativistic magnetohydrodynamical κ-jet models for Sagittarius A

The observed spectral energy distribution of an accreting supermassive black hole typically forms a power-law spectrum in the Near Infrared (NIR) and optical wavelengths, that may be interpreted as a signature of accelerated electrons along the jet. However, the details of acceleration remain uncertain. In this paper, we study the radiative properties of jets produced in axisymmetric GRMHD simulations of hot accretion flows onto underluminous supermassive black holes both numerically and semi-analytically, with the aim of investigating the differences between models with and without accelerated electrons inside the jet. We assume that electrons are accelerated in the jet regions of our GRMHD simulation. To model them, we modify the electrons' distribution function in the jet regions from a purely relativistic thermal distribution to a combination of a relativistic thermal distribution and the $\kappa$-distribution function. Inside the disk, we assume a thermal distribution for the electrons. We calculate jet spectra and synchrotron maps by using the ray tracing code {\tt RAPTOR}, and compare the synthetic observations to observations of Sgr~A*. Finally, we compare numerical models of jets to semi-analytical ones. We find that in the $\kappa$-jet models, the radio-emitting region size, radio flux, and spectral index in NIR/optical bands increase for decreasing values of the $\kappa$ parameter, which corresponds to a larger amount of accelerated electrons. The model with $\kappa = 3.5$, $\eta_{\rm acc}=5-10\%$ (the percentage of electrons that are accelerated), and observing angle $i = 30^{\rm o}$ fits the observed Sgr~A* emission in the flaring state from the radio to the NIR/optical regimes, while $\kappa = 3.5$, $\eta_{\rm acc}< 1\%$, and observing angle $i = 30^{\rm o}$ fit the upper limits in quiescence.
Transmit Power Optimization and Feasibility Analysis of Self-Backhauling Full-Duplex Radio Access Systems

We analyze an inband full-duplex access node that is serving mobile users while simultaneously connecting to a core network over a wireless backhaul link, utilizing the same frequency band for all communication tasks. Such wireless self-backhauling is an intriguing option for the next generation wireless systems since a wired backhaul connection might not be economically viable if the access nodes are deployed densely. In particular, we derive the optimal transmit power allocation for such a system in closed form under quality-of-service (QoS) requirements, which are defined in terms of the minimum data rates for each mobile user. For comparison, the optimal transmit power allocation is solved also for two reference scenarios: a purely half-duplex access node, and a relay-type full-duplex access node. Based on the obtained expressions for the optimal transmit powers, we then show that the systems utilizing a full-duplex capable access node have a fundamental feasibility boundary, meaning that there are circumstances under which the QoS requirements cannot be fulfilled using finite transmit powers. This fundamental feasibility boundary is also derived in closed form. The feasibility boundaries and optimal transmit powers are then numerically evaluated in order to compare the different communication schemes. In general, utilizing the purely full-duplex access node results in the lowest transmit powers for all the communicating parties, although there are some network geometries under which such a system is not capable of reaching the required minimum data rates. In addition, the numerical results indicate that a full-duplex capable access node is best suited for relatively small cells.
The relationship between parental psychopathology and children's subtypes of disruptive behavior problems

THE RELATIONSHIP BETWEEN PARENTAL PSYCHOPATHOLOGY AND CHILDREN’S SUBTYPES OF DISRUPTIVE BEHAVIOR PROBLEMS MAY 2006 LAUREN H. GOLDSTEIN, B.A., UNIVERSITY OF MIAMI M.S., UNIVERSITY OF MASSACHUSETTS AMHERST Ph D. , UNIVERSITY OF MASSACHUSETTS AMHERST Directed by: Professor Elizabeth Harvey Parent psychopathology, including parental depression, anxiety, substance abuse, personality disorders, and ADHD, has been shown to be related to children’s behavior development (Chronis et al., 2003). However, much of the research on the relationship between parent psychopathology and children’s behavior problems has not considered children with different subtypes of behavior problems (e.g., those with hyperactivity versus those with oppositional-defiance), has focused on children of elementary schoolage and older, and has focused on maternal psychopathology. The present study examined how mothers’ and fathers’ psychopathology is related to subtypes of behavior problems among preschool-aged children. Participants included 215 children, who were between 38 and 50 months, and their mothers and fathers, who were participating in a longitudinal study of young children with behavior problems. Children’s behavior problems and parent psychopathology were measured using parental questionnaires and
DISTRIBUTION AND ABUNDANCE OF THE AMAZON RIVER DOLPHIN ( INIA GEOFFRENSIS ) AND THE TUCUXI ( SOTALIA FLUVIATILIS ) IN THE UPPER AMAZON RIVER

A boat survey was conducted from 5 to 26 June 1993 to estimate the abundance of the Amazon river dolphin (Inia geoffrensis) and the tucuxi (Sotalia fluviatilis) along ca. 120 km of the Amazon River bordering Colombia, Peru, and Brazil. Two survey methods were used: line transects during 5 d and strip transects during 15 d. The line transects were used to estimate the abundance of both species in the main channels of the Amazon at distances greater than 200 m from river banks and islands, and strip transects were used to estimate abundance in the remainder of the habitat. A total of 29 sightings was obtained using line transects, including 8 of Inia, 15 of Sotalia, and 6 with both species present. The total number of sightings made while using strip transects was 143, including 78 of Inia, 51 of Sotalia, and 14 with both species present. The distributions of sightings with respect to distance from the nearest bank were not significantly different between the two species. Based on the results from the two methods, we estimate that there are 346 (CV = 0.12) Inia and 409 (CV = 0.13) Sotalia in the study area. Overall, the mean group size for Inia was 2.9 individuals and for Sotalia was 3.9 individuals. Inia density (dolphin/km2) was highest in tributaries (4.8), followed by areas around islands (2.7) and along main banks (2.0); while Sotalia density was highest in lakes (8.6), followed by areas along main banks (2.8) and around islands (2.0). These are among the highest densities measured to date for any cetacean.
IN‐SITU ELEMENTAL AND Sr ISOTOPE INVESTIGATION OF HUMAN TOOTH ENAMEL BY LASER ABLATION‐(MC)‐ICP‐MS: SUCCESSES AND PITFALLS*

Trace element and Sr isotope data were obtained by laser ablation- and solution mode-(MC)-ICP-MS analysis for tooth enamel from remains excavated at the New Kingdom period Egyptian colonial and Nubian cemetery site of Tombos (Sudan). Elemental abundances determined by both methods of ICP-MS analysis yielded comparable values; however, 87Sr/86Sr values obtained by laser ablation were higher compared to their solution mode counterparts. This discrepancy is related to the production of a molecular interference—Ca + P + O (overlaps 87Sr); hence the higher 87Sr/86Sr values recorded during ablation analyses. Laser ablation studies of enamel may provide relatively precise 87Sr/86Sr values rather quickly but cannot be used for accurately deciphering historical population migrations.
Overseas dispersal of Hyperolius reed frogs from Central Africa to the oceanic islands of São Tomé and Príncipe

To infer the colonization history of reed frog species endemic to the oceanic islands of São Tomé and Príncipe, Hyperolius molleri and H. thomensis, we quantified phylogeographical structure in the closely related H. cinnamomeoventris species complex, which is broadly distributed across continental Central Africa.
Human Evaluation for Text Simplification : The Simplicity-Adequacy Tradeoff

In this paper we examine human evaluation for text simplification. We find a strong inverse correlation between simplicity and adequacy, hinting that caution should be used when comparing systems across these metrics. Additionally, we examine the impact of test set size and the number of human annotators, finding that test set size is critical while using multiple human annotators has only limited benefit.
Antibody Responses to HIV-1 gp120 Hypervariable Regions in Six Long-Term Non-Progressors

Our long-term goal is to discover the combination of host parameters that help some HIV-infected individuals to resist progression to AIDS. In this study, we examined antibody responses using multiple samples obtained from a cohort of Long-Term Non-Progressors (LTNPs). Our hypothesis is that antibody responses to variable regions of the HIV-1 envelope glycoprotein are involved in reducing the viral load associated with LTNPs and that these specific immune responses influence susceptibility to disease progression. Multiple plasma samples were obtained from patients identified as LTNPs with the objective of characterizing humoral immune response directed to the five hypervariable regions of the envelope glycoprotein. Antibody binding was tested against peptides representing the five hypervariable regions of gp120, as well as against analog peptides representing different isolates of HIV-1 and against recombinant envelope glycoprotein. LTNPs have specific antibodies to the hypervariable regions of the envelope glycoprotein and develop different patterns of antibody recognition to variable epitopes of envelope glycoprotein. These antibodies can be detected using HIV peptides as capture antigens.
