Silver Nanowires: From Scalable Synthesis to Recyclable Foldable Electronics (2011)

A scalable preparation method for high-quality silver nanowires (Ag NWs), which can be used as the electrical circuits for a broad spectrum of ultralow-cost, recyclable, foldable electronics, is presented. Paper-based radio-frequency identification (RFID) tags, light-emitting diode (LED) chip arrays, and 3D origami electrical devices are synthesized. The signal transmittance and biodecomposition of the RFID tags are investigated.
Lack of expression of endometrial prolactin in early implantation failure: a pilot study (2004)

In this pilot study we report a lack of expression of endometrial prolactin during the 'implantation window' in some patients affected by unexplained infertility and repeated miscarriages. These data, in association with those obtained in experimental animals, suggest that the lack of endometrial PRL expression is involved in reproduction failure.
Parathyroid Hormone for Treatment of Osteoporosis (2002)

Parathyroid hormone decreases vertebral fractures and increases spinal bone density in postmenopausal osteoporosis and glucocorticoid-induced osteoporosis, but at the expense of a decrease in radius bone density. The long-term safety and nonvertebral fracture efficacy are unknown.
Construction and Immunological Evaluation of Dual Cell Surface Display of HIV-1 Gag and Salmonella enterica Serovar Typhimurium FliC in Lactobacillus acidophilus for Vaccine Delivery (2012)

Oral vaccines that elicit a mucosal immune response may be effective against human immunodeficiency virus type 1 (HIV-1) because its transmission occurs mainly at the mucosa. The aim of this study was to construct recombinant Lactobacillus for oral delivery of oral vaccines against HIV-1 and to evaluate their immunogenicity. A recombinant Lactobacillus acidophilus strain expressing the HIV-1 Gag on the bacterial cell surface was established by fusion with the signal peptide and anchor motif of a mucus binding protein (Mub) from L. acidophilus with or without coexpression of Salmonella enterica serovar Typhimurium flagellin (FliC) fused to a different Mub signal peptide and anchor. Using HEK293 cells engineered to express Toll-like receptor 5 (TLR5), the biological activity of FliC on the bacterial cell surfaces was determined. The surface-exposed flagellin retained its TLR5-stimulating activity, suggesting that the recombinant strain with Gag and FliC dual display might provide a different immunopotency than the strain expressing only Gag. The immunological properties of the recombinant strains were assessed by coculture with human myeloid dendritic cells (DCs). The heterologous antigens on the cell surface affected maturation and cytokine responses of DCs. Acquired immune responses were also investigated by intragastric immunization of mice. The enzyme-linked immunosorbent spot assay showed induction of gamma interferon-producing cells at local mucosa after immunization of mice with the Gag-producing strain. Meanwhile, the immunization with L. acidophilus displaying both Gag and FliC resulted in an increase of Gag-specific IgA-secreting cells. These results suggested that the Gag-displaying L. acidophilus elicited specific immune responses and the coexistence of FliC conferred an adjuvant effect on local IgA production.
New process makes production of highly acid gas economical (1982)

Snamprogetti's Cryofrac process combines cryogenic distillation with solvent absorption to profitably treat natural gas containing up to 80% acid gas. The distillation produces an acid-gas stream containing 15-30% acid gas that is washed out with a physical absorbent. Expansion and vaporization of the acid stream refrigerates the distillation, making it a low-energy-consumption process.
Evaluation of Control Schemes for Thyristor-Controlled DC Motors (1978)

Phase-angle control (PAC) is commonly used in the solid-state control of dc motor drives. This paper investigates other control schemes, such as symmetrical-angle control (SAC), extinction-angle control (EAC), current-limit control (CLC), and time-ratio control (TRC). The drive system with the control schemes is simulated on a digital computer and an efficient time-saving method is used for computation. The performance characteristics, such as torque speed, input power factor, fundamental power factor, harmonic content, and peak motor current are obtained and compared for the different control schemes. Each control scheme has certain advantages over the others. The control schemes are implemented on an experimental setup to demonstrate the basic principles of operation.

An Innovative Self-Configuration Approach for Networked Systems and Applications (2006)

The increased complexity, heterogeneity and the dynamism of networked systems and services make current control and management tools to be ineffective in managing and securing such systems and services. A new paradigm to control and manage large-scale complex and dynamic networked systems is critically needed. In this paper, we present a new paradigm based on the principles of autonomic computing that can handle efficiently complexity, dynamism and uncertainty in networked systems and their applications. We have developed a general Component Management Interface (CMI) to enable autonomic behaviors and operations of any legacy resource or a software component. The CMI consists of four management ports: Configuration Port, Function Port, Control Port and Operation Port. We have successfully implemented the CMI in XML format and validated the effectiveness and performance of our approach to develop automated and self-configuring security patch deployment services.
Capillary-Force-Assisted Self-Assembly (CAS) of Highly Ordered and Anisotropic Graphene-Based Thin Films (2013)

We report capillary-force-assisted self-assembly (CAS) as a method for preparation of thin films of chemically reduced graphene oxide (rGO) with unidirectional organization of rGO sheets. The films were initiated at the contact line of the air–liquid–solid interface and form directly on solid substrates dipped in an isotropic colloidal suspension of rGO. Assisted by capillary forces at the contact line, the suspension undergoes an isotropic-to-anisotropic phase transition and becomes aligned with the film growth direction as the contact line moves across the substrate surface. We determined the degree of order in rGO films and assemblies by birefringence and diattenuation imaging. The slow axis of the rGO platelets within the CAS films displayed a narrow angular distribution (±3°) within a film area of 1 mm2, resulting in the highest possible order parameter (S) of ∼1 with 8-fold enhancement of electrical conductivity compared to films formed by traditional techniques such as filtration. Our straightforward film fabrication technique is scalable to produce large areas of films, and by controlling the rates of convective to diffusive mass transport, films with varying degree of order can be produced.
Analysis of the end-effects in magnetic gears and magnetically geared machines (2014)

Magnetic gears and integrated magnetically geared machines have recently received much attention due to their exceptionally high torque densities. As in the design and analysis of conventional electrical machines, the finite element method (FEM) has been widely used for this class of electrical machine. For the sake of computational efficiency, the standard practice in FEM modeling is to reduce the problem complexity by applying only two-dimensional (2D) modeling and exploiting periodicity, if any. However, it has been shown by many researchers that there exists a significant discrepancy between the results from two-dimensional and three-dimensional (3D) FEM for these machines. Whilst it is generally believed that this discrepancy is due to severe end-effects, there has been no published work specifically looking into the end-effect mechanisms at work in these machines. This paper attempts to identify the origins of these end-effects and explain why they can be especially significant in magnetic gears and magnetically geared machines. The effect of some critical design parameters on the stall torque is investigated by using both 2D and 3D FEM. Special attention is given to the difference between 2D and 3D results, which helps to establish whether or to what extent 2D FEM can be utilized for the design analysis of these special machines. The impact that end-effects have on the stator load factor, a useful concept in the design of magnetically geared machines, is also investigated.
An Efficient Gradient Descent Approach to Secure Localization in Resource Constrained Wireless Sensor Networks (2012)

Many applications of wireless sensor networks require precise knowledge of the locations of constituent nodes. In these applications, it is desirable for the nodes to be able to autonomously determine their locations before they start sensing and transmitting data. Most localization algorithms use anchor nodes with known locations to determine the positions of the remaining nodes. However, these existing techniques often fail in hostile environments where some of the nodes may be compromised by adversaries and used to transmit misleading information aimed at preventing accurate localization of the remaining sensors. In this paper, a computationally efficient secure localization algorithm that withstands such attacks is described. The proposed algorithm combines iterative gradient descent with selective pruning of inconsistent measurements to achieve high localization accuracy. Results show that the proposed algorithm utilizes fewer computational resources and achieves an accuracy better than or comparable to that of existing schemes. The proposed secure localization algorithm can also be used in mobile sensor networks, where all nodes are moving, to estimate the relative locations of the nodes without relying on anchor nodes. Simulations demonstrate that the proposed algorithm can find the relative location map of the entire mobile sensor network even when some nodes are compromised and transmit false information.
Optimisation of Turnip (Brassica Rapa) Protoplast Culture for Cauliflower Mosaic Virus Transformation (1983)

Cauliflower Mosaic Virus is one of the rare plant DNA viruses and consequently a potential vector for genetic engineering (1). Natural infection and proliferation, as judged from ‘mosaic symptoms’, is restricted to a relatively narrow host range, including predominantly members of the Crucifereae. One of the most effective hosts for CaMV is turnip (Brassica rapa ssp. sativa var.rapifera). Natural virus transmission is via aphids and experimental infection via mechanical wounding of leaf epidermis. CaMV spreads systemically through the plant starting from the infection site. (2). We are interested in developing, as an alternative to the Agrobacterium tumefaciens mediated transformation system, a CaMV-based transformation system which makes use of the strong CaMV promotor capacity and the high copy number per cell. One of the basic experimental prerequisites for this aim is a routine protocol for efficient development of proliferating, protoplast-derived cell cultures. The development of such a protocol is the aim of the present study.
Inference Using Message Propagation and Topology Transformation in Vector Gaussian Continuous Networks (2013)

We extend Gaussian networks - directed acyclic graphs that encode probabilistic relationships between variables - to its vector form. Vector Gaussian continuous networks consist of composite nodes representing multivariates, that take continuous values. These vector or composite nodes can represent correlations between parents, as opposed to conventional univariate nodes. We derive rules for inference in these networks based on two methods: message propagation and topology transformation. These two approaches lead to the development of algorithms, that can be implemented in either a centralized or a decentralized manner. The domain of application of these networks are monitoring and estimation problems. This new representation along with the rules for inference developed here can be used to derive current Bayesian algorithms such as the Kalman filter, and provide a rich foundation to develop new algorithms. We illustrate this process by deriving the decentralized form of the Kalman filter. This work unifies concepts from artificial intelligence and modern control theory.
Distributed constrained heuristic search (1991)

A model of decentralized problem solving, called distributed constrained heuristic search (DCHS), that provides both structure and focus in individual agent search spaces to optimize decisions in the global space, is presented. The model achieves this by integrating decentralized constraint satisfaction and heuristic search. It is a formalism suitable for describing a large set of distributed artificial intelligence problems. The notion of textures that allow agents to operate in an asynchronous concurrent manner is introduced. The use of textures coupled with distributed asynchronous backjumping, a type of distributed dependency-directed backtracking that the authors have developed, enables agents to instantiate variables in such a way as to substantially reduce backtracking. The approach has been tested experimentally in the domain of decentralized job-shop scheduling. A formulation of distributed job-shop scheduling as a DCHS and experimental results are presented.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Structure and Infectivity of Picornaviral RNA Encapsidated by Cowpea Chlorotic Mottle Virus Protein (1973)

Poliovirus and Mengo virus RNA were shown to associate efficiently with cowpea chlorotic mottle virus protein to form pseudovirions. The sedimentation coefficient for the pseudovirions was similar to that of poliovirus, and electron microscope observations showed the Mengo pseudovirions to be similar in size to Mengo virus. Such pseudovirions were infectious and were more resistant to ribonuclease than viral RNA; however, under our assay conditions, their infectivity was about equal to that of viral RNA.
Further Development of Artificial Pancreas: Blocked by Patents? (2008)

Patent activity in the field of medical device technology and especially in the area of artificial pancreas development has surged in recent years. According to the search presented in this article, the number of granted U.S. patents in the area of closed-loop glucose control (CLGC) increased from 24 filed in 1991 to 247 filed in 2001. A company active in the area of diabetes technology development will likely need to understand a patent landscape consisting of hundreds of patents. Currently, both in the United States and in Europe, patentability requirements seem to be raised in order to ensure patent quality. However, the current patent landscape reflects the work of the patent offices in the past, as already granted patents are not affected by changes made to the patent grant procedure today.Regarding the increasing amount of patents and considering the complexity of CLGC systems, the attempt to develop a CLGC system will become more and more venturesome regarding the risk of infringement of already existing patents. The consequence of this situation can be that less innovation takes place.This article highlights some important general aspects of the patent system, briefly characterizes the current CLGC patent landscape, and illustrates by means of two exemplary patents what one angle of said patent landscape looks like. It is our opinion that, in order to support the rapid development of an artificial pancreas for patients with diabetes, adequate action to lower this hurdle should be undertaken by a consortium of all parties involved (industries, patient organizations, health-care professionals, and institutional payers).

Rate-distortion optimized tree-structured compression algorithms for piecewise polynomial images (2005)

This paper presents novel coding algorithms based on tree-structured segmentation, which achieve the correct asymptotic rate-distortion (R-D) behavior for a simple class of signals, known as piecewise polynomials, by using an R-D based prune and join scheme. For the one-dimensional case, our scheme is based on binary-tree segmentation of the signal. This scheme approximates the signal segments using polynomial models and utilizes an R-D optimal bit allocation strategy among the different signal segments. The scheme further encodes similar neighbors jointly to achieve the correct exponentially decaying R-D behavior (D(R) - c(o)2(-c1R)), thus improving over classic wavelet schemes. We also prove that the computational complexity of the scheme is of O(N log N). We then show the extension of this scheme to the two-dimensional case using a quadtree. This quadtree-coding scheme also achieves an exponentially decaying R-D behavior, for the polygonal image model composed of a white polygon-shaped object against a uniform black background, with low computational cost of O(N log N). Again, the key is an R-D optimized prune and join strategy. Finally, we conclude with numerical results, which show that the proposed quadtree-coding scheme outperforms JPEG2000 by about 1 dB for real images, like cameraman, at low rates of around 0.15 bpp.
Strengthening of shear-damaged RC beams by external bonding of steel plates (1995)

The repair and strengthening of damaged reinforced concrete (RC) beams using externally bonded steel plates has gained universal acceptance. This study presents test results and their interpretation for shear-damaged RC beams with deficient shear strength, strengthened by externally bonded steel plates. Different arrangements of steel plates were used in order to eliminate shear failure and develop ductile behaviour. The strength of all repaired beams was increased and the degraded stifiess of the beams was restored. However, the failure was sudden due to plate separation for most repaired beams, with the exception of beams repaired with full encasement at the shear zone. Such jacket-type repair enhanced the shear capacity and was so effective thatJIexural failure occurred for these beams.
1.7kV high-power IGBT fabrication by bonded-wafer-concept (2015)

Lower losses and higher performance levels at elevated junction temperatures require fabrication processes enabling full design-flexibility for the IGBT buffer and anode to meet application requirements for the ≤1.7kV voltage-range. Here we present the bonded wafer concept that is enabling high thermal stability and soft and high turn-off capability due to full design flexibility for the critical backside layers.
Regression of oral Kaposi's sarcoma in a case of AIDS on Zidovudine (AZT) (1989)

A case with oral Kaposi's sarcoma (KS) is reported that regressed during therapy with Zidovudine (AZT) which was started 5 months after the first dermal and oral tumours were noted. After 6 months of treatment the absolute number of T-helper cells had increased from 54/microliters to 232/microliters and the ratio of T-helper to T-suppressor cells from 0.15 to 0.3. During the same time the lesions of KS on the gingiva, uvula and the body as well as the face disappeared. The lesion of KS on the hard palate regressed.
[Expression and significance of hypoxia inducible factor-1 alpha in hepatocellular carcinoma tissues]. (2006)

HIF1 alpha protein is obviously expressed in HCC and it is mainly affected by hypoxia. The expression of HIF1 alpha is related to the differentiation of the HCC and its intrahepatic and extrahepatic metastases but has no correlation to the existence of portal vein tumor emboli, the status of HBsAg and the prognosis.
Performance evaluation of D-SPECT: a novel SPECT system for nuclear cardiology (2009)

D-SPECT (Spectrum Dynamics, Israel) is a novel SPECT system for cardiac perfusion studies. Based on CZT detectors, region-centric scanning, high-sensitivity collimators and resolution recovery, it offers potential advantages over conventional systems. A series of measurements were made on a beta-version D-SPECT system in order to evaluate its performance in terms of energy resolution, scatter fraction, sensitivity, count rate capability and resolution. Corresponding measurements were also done on a conventional SPECT system (CS) for comparison. The energy resolution of the D-SPECT system at 140 keV was 5.5% (CS: 9.25%), the scatter fraction 30% (CS: 34%), the planar sensitivity 398 s(-1) MBq(-1) per head ((99m)Tc, 10 cm) (CS: 72 s(-1) MBq(-1)), and the tomographic sensitivity in the heart region was in the range 647-1107 s(-1) MBq(-1) (CS: 141 s(-1) MBq(-1)). The count rate increased linearly with increasing activity up to 1.44 M s(-1). The intrinsic resolution was equal to the pixel size, 2.46 mm (CS: 3.8 mm). The average reconstructed resolution using the standard clinical filter was 12.5 mm (CS: 13.7 mm). The D-SPECT has superior sensitivity to that of a conventional system with similar spatial resolution. It also has excellent energy resolution and count rate characteristics, which should prove useful in dynamic and dual radionuclide studies.
