A new type of wide spectral coverage echelle spectrometer design for ICP-AES (2012)

The inductively coupled plasma atomic emission spectrometry (ICP-AES) has always attracted great interest and is widely used for routine elemental analysis. While one drawback of this technique is the fact that conventional Czerny- Turner spectrographs in combination with CCD cameras are very limited either in terms of spectral resolution or in terms of simultaneously detectable spectral range. A cross-dispersion system with echelle grating and prism has therefore been developed, and the spectral image is directed by large area charge coupled device (CCD). This configuration meets the needs of atomic emission spectroscopy well, since it has many benefits including high resolving power, spectral coverage, high sensitivity, and high optical throughput. While, because the limitation of the development of detectors, it is difficult to complete wide spectral coverage measurement. Due to the improvements in optical design, this system can detect the wide spectral coverage from 180nm to 900nm simply by rotating the prism, and these two ranges are 180nm- 260nm and 210nm-900nm, with a high resolution 0.009nm@200nm. The detection of different elements only needs to choose appropriate wavelength coverage, thus lots of elements can be analyzed within quite short time. The novel optical design of this instrument is presented in this paper and its merits are discussed. The optical spectral resolution and the precision of wavelength calibration are found to be satisfactory and within design goals. Experiments show that the ICPAES with echelle spectrometer is available to detect multiple elements within a short time correctly, and the wavelength precision is better than 0.01nm.
Study of 2-bit Antenna–Filter–Antenna Elements for Reconfigurable Millimeter-Wave Lens Arrays (2006)

This paper presents a new reconfigurable antenna-filter-antenna (AFA) element based on slot antennas and switchable resonators. This reconfigurable AFA can operate in four modes of operation as a three- or four-pole filter, and yields a 2-bit variable phase delay. As a result, the multimode AFA can be used as the building block of 2-bit adaptive lens arrays. This paper details design, modeling, and miniaturization of the reconfigurable AFA, and demonstrates its performance through preconfigured prototypes. The proposed AFA has a loss of 1.4-1.6 dB measured at 32 GHz in both three- and four-pole filter modes, and exhibits a frequency response that is almost insensitive to the angle of incidence. Several proof-of-concept fixed lens arrays have been also fabricated for output beams scanned to 0deg, 15deg, 30deg, 45deg, and 60deg in the E- and H-plane. The measurement results show that the output beam can be scanned to plusmn60deg in both principle planes, with a worst case sidelobe level of less than -11 dB and a scan loss that hardly exceeds the theoretical limit
Porous Monofilaments by Continuous Solid-State Foaming (2002)

We report a new semicontinuous process for the production of porous polyetherimide monofilaments. Dense, carbon-dioxide-saturated fibers are spun at rates up to 1 m/s, and porosity is introduced at the spinning head, which establishes the transition from the pressure cell to the heating bath. The process is designed to control independently the carbon dioxide saturation level of the swollen fiber and the temperature during expansion. This subtle control of process conditions allows for the production of closed microcellular as well as open nanoporous monofilaments. The microstructure of the porous monofilaments obtained in our process can be tailored on the basis of a detailed “foam diagram” obtained previously in a discontinuous characterization method. The foam diagram identifies closed microcellular and open nanoporous regions in a temperature versus concentration map.
Factors influencing in vitro production of colony-stimulating factor by mononuclear leukocytes from humans. (1979)

The purpose of this study was to identify factors that influence the production of colony-stimulating factor by leukocytes of humans. The use of nonadherent light-density bone marrow cells is semisolid agar cultures to assay the concentrations of colony-stimulating factor in the supernatant of monocyte and mononuclear leukocyte cultures made it possible to distinguish between colony-stimulating factor, which stimulates colony-forming cells directly, and monocyte-dependent stimulating activity, which acts indirectly, by increasing the monocyte production of colony-stimulating factor. Colony-stimulating factor was not detectable in the cytosol of monocytes; that detected in culture must, therefore, have been newly synthesized. Synthesis was enhanced independently by heat-inactivated human serum and by semipurified serum fractions enriched with monocyte-dependent stimulating activity. The kinetics of the production of colony-stimulating factor in the presence and absence of monocyte-dependent stimulating activity indicated that the latter facilitated monocyte production of the former. Factors released from neutrophils were shown to reduce the production of colony-stimulating factor and thr proliferation of colony-forming cells and thus may provide a feedback control mechanism limiting the proliferation of neutrophils.
Digital phase-locked loop with wide lock-in range using fractional divider (2002)

The authors propose a novel type of digital phase-locked loop (DPLL) with both a wide initial lock-in range and a fast initial acquisition time. In this DPLL, by using a fractional divider, it is possible for an initial fixed clock to be made as the adapting free-running frequency which is dependent on the input frequency. Therefore, one can obtain a wide initial lock-in range. Furthermore, removing the frequency offset by a fractional divider and resetting the divider, this system has a fast initial acquisition time of only 16 cycles of input. The properties of the proposed DPLL are investigated by experiments and theoretical analysis, and they are compared with those of the conventional DPLL. The results show that the proposed DPLL performs well.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Properties of an adaptive feedback equalization algorithm. (1993)

This paper describes a new approach to feedback equalization for hearing aids. The method involves the use of an adaptive algorithm that estimates and tracks the characteristic of the hearing aid feedback path. The algorithm is described and the results of simulation studies and bench testing are presented.
Simulation system modeling for mass customization manufacturing (2003)

Emerging rapidly as a new paradigm of the 21st century, mass customization manufacturing (MCM) systems possess some special characteristics that make the modeling of such systems extremely difficult. These characteristics include concurrency, synchronization, and cooperation among subsystems. Moreover, MCM emphasizes shortened product life-cycles, which means production lines have to be changed or reconfigured frequently. Highly flexible and re-configurable factories must be designed, simulated, and analyzed. To support the development and analysis of these systems, new approaches to modeling and simulation must be developed. In this paper, a methodology for representing manufacturing systems using a valid, colored Petri net is presented. This method for modeling and simulating is flexible enough to support the dynamic nature of the operation of MCM systems. It is able to represent solutions to problems such as dynamic rescheduling, shop reconfiguration, part rework processing, and mechanisms for recovery from machine failure. MCM systems must often support product design modifications at late stages of production, and must respond and adjust to these changes quickly, without postponing delivery time.

Document layout analysis based on emergent computation (2002)

A new method of document layout analysis is proposed for a document reader, to be used for reading a wide variety of documents. Emergent computation, which is a key concept of artificial life, is adopted to analyze various complex document structures. The proposed method uses a multilayer architecture consisting of four subsystems: region extraction, region analysis, region recognition, and region modification. Emergent computation is used for the interactions between subsystems to produce effective and flexible behavior of the entire system. The global layout structure of a document is extracted from these interactions. Experimental results obtained for 150 documents show the method is adaptable to various layout structures in documents.
Low-jitter on-chip clock for RSFQ circuit applications (1999)

The ultra-narrow linewidth of a long Josephson junction (LJJ) oscillator offers low timing jitter as a clock source. In this paper, we will discuss the improvement of an LJJ clock by using an annular geometry. We demonstrate the integration of an annular LJJ with a clock decimator which consists of a serial chain of toggle-flip-flops (TFFs). Each TFF divides its input frequency by a factor of 2. We have also developed a clock frequency selector. The clock selector circuit can choose either the master clock fm or one of its sub-harmonics (fm/2m, m = 1 to n), based on the select inputs. The generation of a set of clocks will enable us to integrate the on-chip LJJ clock with a flash analogue-to-digital converter.
Totalrecall (2007)

We introduce a system for visualizing, annotating, and analyzing very large collections of longitudinal audio and video recordings. The system, TotalRecall, is designed to address the requirements of projects like the Human Speechome Project, for which more than 100,000 hours of multitrack audio and video have been collected over a twentytwo month period. Our goal in this project is to transcribe speech in over 10,000 hours of audio recordings, and to annotate the position and head orientation of multiple people in the 10,000 hours of corresponding video. Higher level behavioral analysis of the corpus will be based on these and other annotations. To efficiently cope with this huge corpus, we are developing semi-automatic data coding methods that are integrated into TotalRecall. Ultimately, this system and the underlying methodology may enable new forms of multimodal behavioral analysis grounded in ultradense longitudinal data.
Diagnosis and Treatment of Syphilis (1971)

IN spite of excellent methods for diagnosing and treating syphilis, the disease is still widespread. There was a marked upsurge in the reported cases of infectious (primary and secondary) syphilis in the United States in the late 1950's and early 1960's, which reached a peak in 1965, when over 25,000 cases were reported.1 A gradual decrease in reported cases of infectious syphilis occurred after 1965, but in the first seven months of 1970 a steady, 10 to 12 per cent, increase in cases is again being reported.2 Moreover, the true incidence is undoubtedly much higher.

Immunoregulatory Role of NK Cells in Tissue Inflammation and Regeneration (2017)

NK cells represent an important first line of defense against viral infection and cancer and are also involved in tissue homeostasis. Studies of NK cell activation in the last decade have revealed that they are able to respond to the inflammatory stimuli evoked by tissue damage and contribute to both progression and resolution of diseases. Exacerbation of the inflammatory response through interactions between immune effector cells facilitates the progression of non-alcoholic fatty liver disease (NAFLD) into steatosis, cirrhosis, and hepatocellular carcinoma (HCC). When hepatic damage is incurred, macrophage activation is crucial for initiating cross talk with neighboring cells present in the liver, including hepatocytes and NK cells, and the importance of this interaction in shaping the immune response in liver disease is increasingly recognized. Inflicted structural damage can be in part regenerated <i>via</i> the process of self-limiting fibrosis, though persistent hepatic damage will lead to chronic fibrosis and loss of tissue organization and function. The cytotoxic activity of NK cells plays an important role in inducing hepatic stellate cell apoptosis and thus curtailing the progression of fibrosis. Alternatively, in some diseases, such as HCC, NK cells may become dysregulated, promoting an immunosuppressive state where tumors are able to escape immune surveillance. This review describes the current understanding of the contributions of NK cells to tissue inflammation and metabolic liver diseases and the ongoing effort to develop therapeutics that target the immunoregulatory function of NK cells.

Pixida (2015)

In the era of global-scale services, big data analytical queries are often required to process datasets that span multiple data centers (DCs). In this setting, cross-DC bandwidth is often the scarcest, most volatile, and/or most expensive resource. However, current widely deployed big data analytics frameworks make no attempt to minimize the traffic traversing these links. In this paper, we present P ixida , a scheduler that aims to minimize data movement across resource constrained links. To achieve this, we introduce a new abstraction called S ilo , which is key to modeling P ixida 's scheduling goals as a graph partitioning problem. Furthermore, we show that existing graph partitioning problem formulations do not map to how big data jobs work, causing their solutions to miss opportunities for avoiding data movement. To address this, we formulate a new graph partitioning problem and propose a novel algorithm to solve it. We integrated P ixida in Spark and our experiments show that, when compared to existing schedulers, P ixida achieves a significant traffic reduction of up to ~ 9x on the aforementioned links.

CNS SIRT3 Expression Is Altered by Reactive Oxygen Species and in Alzheimer’s Disease (2012)

Progressive mitochondrial dysfunction contributes to neuronal degeneration in age-mediated disease. An essential regulator of mitochondrial function is the deacetylase, sirtuin 3 (SIRT3). Here we investigate a role for CNS Sirt3 in mitochondrial responses to reactive oxygen species (ROS)- and Alzheimer's disease (AD)-mediated stress. Pharmacological augmentation of mitochondrial ROS increases Sirt3 expression in primary hippocampal culture with SIRT3 over-expression being neuroprotective. Furthermore, Sirt3 expression mirrors spatiotemporal deposition of β-amyloid in an AD mouse model and is also upregulated in AD patient temporal neocortex. Thus, our data suggest a role for SIRT3 in mechanisms sensing and tackling ROS- and AD-mediated mitochondrial stress.

All-optical routing and switching for three-dimensional photonic circuitry (2011)

The ability to efficiently transmit and rapidly process huge amounts of data has become almost indispensable to our daily lives. It turned out that all-optical networks provide a very promising platform to deal with this task. Within such networks opto-optical switches, where light is directed by light, are a crucial building block for an effective operation. In this article, we present an experimental analysis of the routing and switching behaviour of light in two-dimensional evanescently coupled waveguide arrays of Y- and T-junction geometries directly inscribed into fused silica using ultrashort laser pulses. These systems have the fundamental advantage of supporting three-dimensional network topologies, thereby breaking the limitations on complexity associated with planar structures while maintaining a high dirigibility of the light. Our results show how such arrays can be used to control the flow of optical signals within integrated photonic circuits.
The occurrence and effect of a protozoan parasite, <i>Ophryocystis elektroscirrha</i> (Neogregarinida: Ophryocystidae) on overwintering monarch butterflies, <i>Danaus plexippus</i> (Lepidoptera: Danaidae) from two California winter sites (1992)

Abstract. Monarch butterflies, Danaus plexippus , from two overwintering populations, were found to have Ophryocystis elektroscirrha spores on their scales at rates between 53% and 68%. The frequency of butterflies with O.elektroscirrha spores remained about the same between sites and throughout the winter. The spores, recovered from all parts of the body of the butterfly, were most numerous on the abdomen, particularly near the posterior third. Butterflies with spores survived as long as those without detectable spores at 10.1°C ±0.4 SE and 78.3% r.h. ±0.6SE. Insects with spores held at 19.4°C ±0.4SE and 44.9% r.h. ±1.5SE showed a significantly higher rate of moisture loss and survived a shorter period than monarch butterflies without detectable spores.
Minimum selection GSC and adaptive low-power rake combining scheme (2003)

In this paper, we investigate a new generalized selection combining (GSC) technique and an adaptive low-power rake combining scheme to save the power consumption of mobile rake receivers for wideband CDMA systems. The new GSC technique called minimum selection GSC (MS-GSC) selects a minimum number of rake fingers as long as the combined SNR is larger than a given threshold. The proposed rake combining scheme adaptively adjusts the threshold value to maintain the desired BER, in which a GSC dynamically selects rake fingers to meet the given threshold condition. The proposed MS-GSC shows a low standard deviation in bit error statistics and advantages practical implementation. The proposed adaptive scheme works well with existing GSC schemes as well as the proposed MS-GSC. The proposed scheme reduced the power consumption of a mobile rake receiver up to 67.8% by turning off unselected rake fingers.
Building of HD MACs Using Cell Processing Robot for Cartilage Regeneration (2012)

We have been working on the development of scaffold free cell delivery system, and showing good results in the regeneration of rabbit osteochondral defect for more than three years by implantation of molded mesenchymal stem cells construct without use of exogenous factors. The entire procedure is simple, yet it takes time and labor to build a single construct by even experienced hands. Therefore, this study was aimed to develop a cell processing robot for building scaffoldfree HD MACs (High-Density Mesenchymal stem cell Autologous Constructs) for cartilage regeneration. As a result, the scaffold-free HD MACs could be obtained with manual procedure just as the same without contamination. We have implanted the construct in a rabbit with osteochondral defect in the knee. In this study, we have developed a cell processing robot for cartilage regeneration. The entire system is almost GMP ready. We are preparing clinical trials at Kyushu University Hospital for HD MACs implantation to cartilage defect with this robot system.
Reliability-based optimal task-allocation in distributed-database management systems (1997)

A distributed database management system (DDBMS) manages a collection of data stored at various processing nodes of a computer network. Global queries are processed by DDBMS, and tasks (join operations in these queries) are assigned to various nodes in the network. Optimal allocation of these tasks are discussed, with reliability as the objective function and communication-cost as the constraint function. A model for reliability-based task allocation is developed. It is converted into a state-space search-tree and is implemented using a branch-and-bound algorithm. The query is considered as a multiple join problem (MJP). Reliable task-allocations for all permutations of MJP are found. The permutation which has minimum cost of data transmission is calculated. A method is suggested for calculating the reliability of the path that a DDBMS network follows to deliver a message to the receiver, given the number of spoolers.
