Everything You Should Know About Intel SGX Performance on Virtualized Systems (2019)

Intel SGX has attracted much attention from academia and is already powering commercial applications. Cloud providers have also started implementing SGX in their cloud offerings. Research efforts on Intel SGX so far have mainly concentrated on its security and programmability. However, no work has studied in detail the performance degradation caused by SGX in virtualized systems. Such settings are particularly important, considering that virtualization is the de facto building block of cloud infrastructure, yet often comes with a performance impact. This paper presents for the first time a detailed performance analysis of Intel SGX in a virtualized system in comparison with a bare-metal system. Based on our findings, we identify several optimization strategies that would improve the performance of Intel SGX on such systems.
Characterization of three propane-inducible oxygenases in Mycobacterium sp. strain ENV421 (2012)

This study describes the first example of a propane-inducible P450 with a broad substrate specificity, including linear alkanes, alkylbenzenes and a multiring compound. The induction of three distinct oxygenase classes by propane is also an interesting finding because it might explain why propane serves as an effective stimulant that promotes the biodegradation of a various environmental contaminants.
Harmonic reduction in low-cost power supplies (2002)

Power electronic loads inject harmonic currents into the utility system. The large increase of power consumption will inevitably lead to deteriorating power quality due to the popularity of switch-mode power electronic equipment. Designers must satisfy two requirements. First obtain nearly sinusoidal line currents to comply with the international standard IEC 1000-3-2, and second achieve low cost, high operating efficiency and reliability to be competitive in the marketplace. In this paper we analyze the way to reduce the size and cost of the passive filters and still provide compliance with the international harmonic reduction regulations for low-power and low-cost applications.
A study on the bending mechanism of the flexible ureteroscope (2010)

Flexible ureteroscope is increasingly used for urologic treatment today. The key mechanism of the ureteroscope is the bending mechanism. It consists of a bending head and a control lever connected through a set of wire. The lighting and imaging optics as well as the surgical tools all go through the bending head. With the demand for improved performance and reduced size, more research on its design is still needed. In this paper, the modeling and simulation of an ureteroscope are presented, which pave the road for design optimization in the future.
Synthesis of Monodisperse Bi‐Compartmentalized Amphiphilic Janus Microparticles for Tailored Assembly at the Oil–Water Interface (2016)

Janus particles endowed with controlled anisotropies represent promising building blocks and assembly materials because of their asymmetric functionalities. Herein, we show that using the seeded monomer swelling and polymerization technique allows us to obtain bi-compartmentalized Janus microparticles that are generated depending on the phase miscibility of the poly (alkyl acrylate) chains against the polystyrene seed, thus minimizing the interfacial free energy. When tetradecyl acrylate is used, complete compartmentalization into two distinct bulbs can be achieved, while tuning the relative dimension ratio of compartmented bulb against the whole particle. Finally, we have demonstrated that selectively patching the silica nanoparticles onto one of the bulb surfaces gives amphiphilicity to the particles that can assemble at the oil-water interface with a designated level of adhesion, thus leading to development of a highly stable Pickering emulsion system.
Measurement of normal ocular volume by the use of computed tomography (2013)

Ocular volume correlated positively with the age of the patients to about 50 years after which some reduction was observed. We noted that males had slightly larger eyeballs in comparison to females, although not at statistical significant level.
Analysis of free-storage algorithms-visited (1984)

Most research in free-storage management has centered around strategies that search a linked list and strategies that partition storage into predetermined sizes. Such algorithms are analyzed in terms of CPU efficiency and storage efficiency. The subject of this study is the free-storage management in the Virtual Machine/System Product (VM/SP) system control program. As a part of this study, simulations were done of established, and proposed, dynamic storage algorithms for the VM/SP operating system. Empirical evidence is given that simplifying statistical assumptions about the distribution of interarrival times and holding times has high predictive ability. Algorithms such as first-fit, modified first-fit, and best-fit are found to be CPU-inefficient. Buddy systems are found to be very fast but suffer from a high degree of internal fragmentation. A form of extended subpooling is shown to be as fast as buddy systems with improved storage efficiency. This algorithm was implemented for VM/SP, and then measured. Results for this algorithm are given for several production VM/SP systems.
Text categorization with many redundant features (2004)

Text categorization algorithms usually represent documents as bags of words and consequently have to deal with huge numbers of features. Most previous studies found that the majority of these features are relevant for classification, and that the performance of text categorization with support vector machines peaks when no feature selection is performed. We describe a class of text categorization problems that are characterized with many redundant features. Even though most of these features are relevant, the underlying concepts can be concisely captured using only a few features, while keeping all of them has substantially detrimental effect on categorization accuracy. We develop a novel measure that captures feature redundancy, and use it to analyze a large collection of datasets. We show that for problems plagued with numerous redundant features the performance of C4.5 is significantly superior to that of SVM, while aggressive feature selection allows SVM to beat C4.5 by a narrow margin.
Inhibition of the EGF-Stimulated Cellular Proliferation of ER 22 Cells by Hydroxybiphenyl Derivatives (1995)

Several series of hydroxybiphenyl compounds substituted by a hydrophobic group (tert-butyl or phenyl) and bearing a free or protected carboxylic moiety were synthesized. The compounds were tested for their ability to inhibit the intrinsic tyrosine protein kinase activity of the EGF-receptor in vitro and the EGF-stimulated DNA-synthesis by ER 22 cells. Although the compounds of each series had poor in vitro inhibitory potencies (IC50 >> 100 microM), most of them inhibited the EGF-dependent cellular proliferation of ER 22 cells at relatively low doses (IC50 = 1.1 microM for compound 14). Structure-activity studies based on the cellular results showed that the most interesting series was the linear terphenyl series B of 2'-hydroxy-1,1':4',1"-terphenyl-4-carboxylates. The availability of the hydroxyl group, either protected or unprotected, the linear arrangement of the hydrophobic moiety, the biphenyl skeleton, and the carboxylic group seem to be essential for the activity of the compounds.
Near-zero pretilt alignment of liquid crystals using polyimide films doped with UV-curable polymer (2015)

We propose an alignment method for the near-zero pretilt angle of liquid crystals (LCs) using polyimide films doped with a UV-curable polymer. The near-zero pretilt angle can be obtained by UV curing of reactive mesogen monomers mixed with planar alignment material while a vertical electric field is applied to an LC cell assembled after the rubbing process. We demonstrated that the pretilt angle can be decreased from 2.390° to 0.082° by employing the proposed method.
Einführung (1986)

Die konjunkturellen und strukturellen Krisenerscheinungen im vergangenen Jahrzehnt, die auch mit den noch immer wachsenden Umweltproblemen und der Energiekrise Mitte der 70er Jahre im Zusammenhang stehen, haben zu nicht mehr tragbaren globalen bzw. sektoralen Zahlen und Quoten der Arbeitslosigkeit geführt. Sie haben eine bedeutende Kontraktion bei den Haushalten auf der Ebene des Bundes, der Länder und der Gemeinden bewirkt. Die Investitionstätigkeit der öffentlichen Hand hat einen nicht für möglich gehaltenen Rückgang und schließlich ein kaum mehr vertretbares Niveau erreicht.
An Overview of Gadolinium-Based Oxide and Oxysulfide Particles: Synthesis, Properties, and Biomedical Applications (2021)

In the last decade, the publications presenting novel physical and chemical aspects of gadolinium-based oxide (Gd2O3) and oxysulfide (Gd2O2S) particles in the micro- or nano-scale have increased, mainly stimulated by the exciting applications of these materials in the biomedical field. Their optical properties, related to down and upconversion phenomena and the ability to functionalize their surface, make them attractive for developing new probes for selective targeting and emergent bioimaging techniques, either for biomolecule labeling or theranostics. Moreover, recent reports have shown interesting optical behavior of these systems influenced by the synthesis methods, dopant amount and type, particle shape and size, and surface functionality. Hence, this review presents a compilation of the latest works focused on evaluating the optical properties of Gd2O3 and Gd2O2S particles as a function of their physicochemical and morphological properties; and also on their novel applications as MRI contrast agents and drug delivery nanovehicles, discussed along with their administration routes, biodistribution, cytotoxicity, and clearance mechanisms. Perspectives for this field are also identified and discussed.
Opioid Peptides Mediate the Suppressive Effect of Stress on Natural Killer Cell Cytotoxicity (1984)

The cytotoxic activity of natural killer cells was investigated in rats subjected to one of two inescapable footshock stress paradigms, both of which induce analgesia, but only one via activation of opioid mechanisms. Splenic natural killer cell activity was suppressed by the opioid, but not the nonopioid, form of stress. This suppression was blocked by the opioid antagonist naltrexone. Similar suppression of natural killer activity was induced by high doses of morphine. These results suggest that endogenous opioid peptides mediate the suppressive effect of certain forms of stress on natural killer cell cytotoxicity.
COMPACT AND WIDEBAND DUAL-POLARIZED ANTENNA WITH HIGH ISOLATION FOR WIRELESS COMMUNICATION (2013)

A wideband dual-polarized antenna with high isolation is presented. Four printed quadrant planar folded dipole placed above a U-shaped re∞ector are adopted as the main radiation elements. Curved slots cut on the planar folded dipole are used to reduce the size of the antenna. Parameter is studied, and the values are adjusted in order to obtain wideband and compact properties. Measured results show that the antenna achieves a VSWR < 2:0 from 1.64{2.33GHz. The isolation between the two polarizations is better than 29.5dB. The radius of the quadrant planar folded dipole is only 34mm (about 0.18 wavelength at 1.64GHz).
Management of trusted citations (2003)

We discuss how references and citations within a document to particular sources can be verified and guaranteed. When a document refers through a quotation to another document, the reader should be able to verify that the reference is correct and that any quotation correctly represents the original text. The mechanism we describe enables the authentication of such quotations. It consists of:A notation to be used when expressing quotations. This notation allows a controlled degree of freedom to make alterations from the original text.Different means to check the correctness of such quotations with respect to the cited documents and to quotation rules.
Human-Robot Handshaking using Neural Oscillators (2006)

In this study we propose a framework using neural oscillators for human-robot physical interaction such as “handshaking”. Neural oscillators are used for synchronization and entrainment between human and robot motions. Passiveness of the handshake can be changed by adjusting strength of the synchronization. Joint torque information is taken as an input signal for the neural oscillators, and the neural oscillator generates the desired trajectory of a robot joint. This paper addresses a model structure of the neural oscillator for human-robot physical interaction. The computer simulations of handshaking show the synchronization and the entrainment. Also the experiments with a joint torque sensing robot arm show that a handshake between a robot and a human being is realized by the proposed method. Lastly the validity of the proposed method is examined by a psychological evaluation with a paired comparison method, and it is found that the proposed method is better than conventional impedance control in terms of “Flexible”, “Natural”, “Kind” and “Affinity”.
Resynchronizing variable-length codes for robust image transmission (1999)

Summary form only given. This paper considers instantaneous prefix codes with possibly unequal codeword lengths but specific codewords, such as a Huffman code. Resynchronizing VLC (RVLC) contain one or more synchronizing codewords that resynchronize the decoder regardless of any previous data. Previous applications of optimal resynchronizing VLC have been limited to sources with alphabets of sizes less than 30, while only non-optimal VLC with ad-hoc marker codewords have been applied to image data. This paper adapts a general design algorithm for optimal resynchronizing VLC to JPEG image data, demonstrating its applicability to sources with large alphabets (>1000). In order to ensure that the decoded data is placed properly in the image following resynchronization, the resulting VLC are modified to contain extended synchronizing codewords to serve as markers. Minor modifications to the baseline JPEG coder increase the robustness to errors, and a concealment algorithm locates and repairs errant data. Images coded using the RVLC-JPEG combined with the concealment algorithm are robust to BER as high as 2/spl times/10/sup -4/ and are extremely tolerant of burst errors. The excellent tolerance to both bit and burst errors at high bit rates demonstrates that images coded with such RVLC can be transmitted over imperfect channels suffering bit errors or packet losses without channel coding for the image data. At lower bit rates, while the overhead is non-trivial, the encoded bitstream does not have firm restrictions on numbers or spacings of errors and hence provides more graceful degradation than traditional ECC.
Computing Random Fields (1986)

A program that moves over a 2- or 3-dimensional mesh performing refinements by moving vertices or introducing new ones is a common enough matter. If the data structure for the mesh persists across the entire calculation its management is simple. However, it may be that the mesh data are needed only transiently, and in this case the maintenance of a (possibly enormous) data structure across the whole calculation seems very space-inefficient. This point takes on extra strength when the mesh is supposed to model some random field, such as a mountain range, cloud formation or meadow plain (generated no doubt by a method related to Mandelbrot's fractal curves) when the only use of the mesh is to make a picture for display. Existing methods for dispensing with the need for the whole mesh across the whole calculation complicate the program considerably. This paper proposes the use of co-routines to control the independent update of all edges depending on a changing vertex. In this way facets are passed out as soon as they are complete and can then be displayed and disposed of when convenient. Only visibility issues dictate how long a piece of data survives.
Design of Propellers for Motorsoarers (1979)

A method was developed for the design of propellers of minimum induced loss matched to an arbitrary operating point characterized by disc loading (thrust or power), air density, shaft speed, flight speed, and number of blades. A consistent procedure is outlined to predict the performance of these propellers under off design conditions, or to predict the performance of propellers of general geometry. The examples discussed include a man powered airplane, a hang glider with a 7.5 kW (10 hp) 8,000 rpm engine, and an airplane-like motorsoarer.
Can You Put it All Together: Evaluating Conversational Agents’ Ability to Blend Skills (2020)

Being engaging, knowledgeable, and empathetic are all desirable general qualities in a conversational agent. Previous work has introduced tasks and datasets that aim to help agents to learn those qualities in isolation and gauge how well they can express them. But rather than being specialized in one single quality, a good open-domain conversational agent should be able to seamlessly blend them all into one cohesive conversational flow. In this work, we investigate several ways to combine models trained towards isolated capabilities, ranging from simple model aggregation schemes that require minimal additional training, to various forms of multi-task training that encompass several skills at all training stages. We further propose a new dataset, Blended-SkillTalk, to analyze how these capabilities would mesh together in a natural conversation, and compare the performance of different architectures and training schemes. Our experiments show that multi-tasking over several tasks that focus on particular capabilities results in better blended conversation performance compared to models trained on a single skill, and that both unified or two-stage approaches perform well if they are constructed to avoid unwanted bias in skill selection or are fine-tuned on our new task.
Research on Unmanned Underwater Vehicle Threat Assessment (2019)

The unmanned underwater vehicle (UUV) plays an ever increasing and important role in the modern marine environment. In particular, the tasks of underwater reconnaissance and surveillance, underwater mine hunting and anti-submarine warfare, all poses a serious and dangerous threat to humans. UUV has become the fore-running technology to accomplish such missions. In this paper, a method based on dynamic Bayesian network modeling was proposed to evaluate the UUV in an underwater threat situation. We divided the UUV threats into three categories: environmental factors, platform factors, and mission factors. Through each of these categories, we carried out factor extraction and set up the priori probability according to the characteristics. Setting up the static Bayesian network involved the addition of state transition probability and establishment of the model for assessing the dynamic Bayesian threat situation. By comparing the results of the static and dynamic Bayesian simulation, it was shown that the dynamic Bayesian is superior. Moreover, by analyzing the sensitivity, we recognized the greatest current threat and in response, determined the appropriate UUV countermeasures. The results showed that the dynamic Bayesian method has great practical significance and value for threat assessment.

Immune responses of chickens inoculated with a recombinant fowlpox vaccine coexpressing glycoprotein B of infectious laryngotracheitis virus and chicken IL-18 (2011)

Infectious laryngotracheitis virus (ILTV) is an alphaherpesvirus that causes severe and economically significant respiratory disease in poultry worldwide. Herein, the immunogenicity of two recombinant fowlpox viruses (rFPV-gB and rFPV-gB/IL18) containing ILTV glycoprotein B (gB) and chicken interleukin-18 (IL-18) were investigated in a challenge model. One-day-old specific-pathogen-free chickens were vaccinated by wing-web puncture with the two rFPVs and challenged with the virulent ILTV CG strain. There were differences in antibody levels elicited by either rFPV-gB/IL18 or rFPV-gB as determined using ELISA. The ratios of CD4(+) to CD8(+) in chickens immunized with rFPV-gB/IL18 were higher (P < 0.05) than in those immunized with rFPV-gB, and the level of proliferative response of the T cells in the rFPV-gB/IL18-vaccinated group was higher (P < 0.05) than that in the rFPV-gB group. All chickens immunized with rFPV-gB/IL18 were protected (10/10), whereas only eight of 10 of the chickens immunized with the rFPV-gB were protected. The results showed that the protective efficacy of the rFPV-gB vaccine could be enhanced by simultaneous expression of chicken IL-18.
