We use micropatterning and strain engineering to encapsulate single living mammalian cells into transparent tubular architectures consisting of three-dimensional (3D) rolled-up nanomembranes. By using optical microscopy, we demonstrate that these structures are suitable for the scrutiny of cellular dynamics within confined 3D-microenvironments. We show that spatial confinement of mitotic mammalian cells inside tubular architectures can perturb metaphase plate formation, delay mitotic progression, and cause chromosomal instability in both a transformed and nontransformed human cell line. These findings could provide important clues into how spatial constraints dictate cellular behavior and function. © 2014 American Chemical Society.

ABSTRACT: Smartphones are powerful computing devices that manipulate, store and transmit sensitive data and are becoming increasingly popular for malware attacks as a result. In order to use them for military purposes, a mesh of security techniques are needed in order to contain sensitive data and prevent it from leaving the device in an unapproved manner. Data separation primarily relies on address spaces defined by the operating system and enforced by the MMU of the processor, as well as permissions applied to data stored in files. Writing a new kernel in a secured development environment, or virtualizing the kernel and device drivers to run under a hypervisor, is the most direct way to increase the strength of data separation. However, it has technical limitations, it requires a handset-specific software solution, and it requires support of the handset manufacturer to build a custom system image. Rather than try to isolate all applications from each other, our solution is to isolate just the secure applications. Applying the proposed advanced platform integrity mechanisms along with our secure data transformation for storage and transmission provides a complete solution against the adverse effects of intentional malware or accidental mishaps. BENEFIT: Applying the advanced platform integrity techniques and secure data transformation methods described in this proposal would provide the framework for data protection, integrity, isolation, and authentication for secure applications running on mobile platforms. It ties together a number of both standard and novel security techniques in an easy to use, scalable, and trustworthy manner that has yet to be seen for an enterprise security model. Whether the enterprise is commercial, government, or military, secure communication among them is made possible through disparate networks providers and complex network topologies. The software-only solution can be quickly installed and provisioned for use, remotely updated and managed, as well as remotely uninstalled and wiped clean. The key component of continuous auditing and monitoring of the platform provides the requisite integrity we need to robustly counteract today"s adversarial conditions.

Fuzzy answer set programming (FASP) is a recent formalism for knowledge representation that enriches the declarativity of answer set programming by allowing propositions to be graded. To now, no implementations of FASP solvers are available and all current proposals are based on compilations of logic programs into different paradigms, like mixed integer programs or bilevel programs. These approaches introduce many auxiliary variables which might affect the performance of a solver negatively. To limit this downside, operators for approximating fuzzy answer sets can be introduced: Given a FASP program, these operators compute lower and upper bounds for all atoms in the program such that all answer sets are between these bounds. This paper analyzes several operators of this kind which are based on linear programming, fuzzy unfounded sets and source pointers. Furthermore, the paper reports on a prototypical implementation, also describing strategies for avoiding computations of these operators when they are guaranteed to not improve current bounds. The operators and their implementation can be used to obtain more constrained mixed integer or bilevel programs, or even for providing a basis for implementing a native FASP solver. Interestingly, the semantics of relevant classes of programs with unique answer sets, like positive programs and programs with stratified negation, can be already computed by the prototype without the need for an external tool.

Processing is an open-source, Java-based programming environment designed for artists and visual designers. In this paper we explore the use of the Processing as a tool for constructing interactive and demonstrative applications that enhance the engineering classroom experience. A brief overview of the Processing environment and its application in the classroom is presented. We identify two primary modes of application - digital demonstration and virtual laboratory, and we explore the use of programming in these contexts. Our paper introduces guidelines for development of media-rich learning tools, addressing issues such as interactivity, simulation accuracy, and aesthetics. Examples of classroom experiences using Processing applications are given, including fundamentals of electricity, electronics, and an introduction to controls. Student performance is measured through standardized assessments. Partial results are presented, suggesting increased student performance. © 2011 American Society for Engineering Education.

Microporous membranes act as selective barriers and play an important role in industrial gas separation and water purification. The permeability of such membranes is inversely proportional to their thickness. Synthetic two-dimensional materials (2DMs), with a thickness of one to a few atoms or monomer units are ideal candidates for developing separation membranes. Here, groundbreaking advances in the design, synthesis, processing, and application of 2DMs for gas and ion separations, as well as water desalination are presented. This report describes the syntheses, structures, and mechanical properties of 2DMs. The established methods for processing 2DMs into selective permeation membranes are also discussed and the separation mechanism and their performances addressed. Current challenges and emerging research directions, which need to be addressed for developing next-generation separation membranes, are summarized. © 2016 WILEY-VCH Verlag GmbH & Co.

The fabrication of high-quality-factor polycrystalline TiO2 vertically rolled-up microcavities (VRUMs) by the controlled release of differentially strained TiO2 bilayered nanomembranes, operating at both telecom and visible wavelengths, is reported. Optical characterization of these resonators reveals quality factors as high as 3.8 × 103 in the telecom wavelength range (1520-1570 nm) by interfacing a TiO2 VRUMs with a tapered optical fiber. In addition, a splitting in the fundamental modes is experimentally observed due to the broken rotational symmetry in our resonators. This mode splitting indicates coupling between clockwise and counterclockwise traveling whispering gallery modes of the VRUMs. Moreover, we show that our biocompatible rolled-up TiO2 resonators function at several positions along the tube, making them promising candidates for multiplexing and biosensing applications. © 2014 Optical Society of America.

In this work, we introduce a new concept to fabricate on chip, all solid-state and flexible micro-supercapacitors based on MnOx/Au multilayers, which are compatible with current microelectronics. The micro-supercapacitor exhibits a maximum energy density of 1.75 mW h cm -3 and a maximum power density of 3.44 W cm-3, which are both much higher than the values obtained for other solid-state supercapacitors. At a scan rate of 1 V s-1, a volumetric capacitance of 32.8 F cm-3 is obtained for MnOx/Au multilayer electrodes, which is much higher than the bare MnOx electrode. Electrochemical impedance spectroscopy (EIS) and evolution complex capacitance confirm that the electrical conductivity of MnOx is improved due to the incorporation of gold, and a low relaxation time constant around 5 ms is observed. The MnOx/Au multilayer micro-supercapacitor also shows good long-term cycling stability, with a capacitance retention rate of 74.1% after a large cycling number of 15000 times. Compared with other supercapacitors, which are not portable and are relatively bulky, the device demonstrated here allows fast and reliable applications in a portable and smart fashion. Furthermore, the nature of the process allows the micro-supercapacitor to be integrated with other micro-devices, to meet the need for micro-scale energy storage. © 2013 The Royal Society of Chemistry.

Nanographenes, or extended polycyclic aromatic hydrocarbons, have been attracting renewed and more widespread attention since the first experimental demonstration of graphene in 2004. However, the atomically precise fabrication of nanographenes has thus far been achieved only through synthetic organic chemistry. The precise synthesis of quasi-zero-dimensional nanographenes, i.e. graphene molecules, has witnessed rapid developments over the past few years, and these developments can be summarized in four categories: (1) non-conventional methods, (2) structures incorporating seven- or eight-membered rings, (3) selective heteroatom doping, and (4) direct edge functionalization. On the other hand, one-dimensional extension of the graphene molecules leads to the formation of graphene nanoribbons (GNRs) with high aspect ratios. The synthesis of structurally well-defined GNRs has been achieved by extending nanographene synthesis to longitudinally extended polymeric systems. Access to GNRs thus becomes possible through the solution-mediated or surface-assisted cyclodehydrogenation, or "graphitization," of tailor-made polyphenylene precursors. In this review, we describe recent progress in the "bottom-up" chemical syntheses of structurally well-defined nanographenes, namely graphene molecules and GNRs. © 2015 The Royal Society of Chemistry.

In computational intelligence, the term 'memetic algorithm' has come to be associated with the algorithmic pairing of a global search method with a local search method. In a sociological context, a 'meme' has been loosely defined as a unit of cultural information, the social analog of genes for individuals. Both of these definitions are inadequate, as 'memetic algorithm' is too specific, and ultimately a misnomer, as much as a 'meme' is defined too generally to be of scientific use. In this paper, we extend the notion of memes from a computational viewpoint and explore the purpose, definitions, design guidelines and architecture for effective memetic computing. Utilizing two genetic programming test-beds (the even-parity problem and the Pac-Man video game), we demonstrate the power of high-order meme-based learning, known as meta-learning. With applications ranging from cognitive science to machine learning, meta-learning has the potential to provide much-needed stimulation to the field of computational intelligence by providing a framework for higher order learning. © 2010 ACM.
