Down literal circuit with neuron-MOS transistors and its applications (2003)

A voltage-mode neuron-MOS(/spl nu/MOS) down literal circuit which realizes an arbitrary down literal function is proposed. It provides the benefit that the circuit can be easily fabricated by standard CMOS process, instead of the multi-level ion implantation applied in the conventional circuit. It has a variable threshold voltage by way of controlling only two bias voltages. Its noise margin and switching sensitivity are greater than those of variable-threshold C-VMOS inverter presented by Shibata. The threshold voltage errors of the circuit caused by device parameters mismatch is also analysed. Using the /spl nu/MOS down literal circuits, literal and T-gate circuits are also presented. Performances of the proposed circuits are evaluated using HSPICE simulations with MOSIS 2.0 /spl mu/m CMOS device parameters.
An Online Malicious Spam Email Detection System Using Resource Allocating Network with Locality Sensitive Hashing (2015)

In this paper, we propose a new online system that can quickly detect malicious spam emails and adapt to the changes in the email contents and the Uniform Resource Locator (URL) links leading to malicious websites by updating the system daily. We introduce an autonomous function for a server to generate training examples, in which double-bounce emails are automatically collected and their class labels are given by a crawler-type software to analyze the website maliciousness called SPIKE. In general, since spammers use botnets to spread numerous malicious emails within a short time, such distributed spam emails often have the same or similar contents. Therefore, it is not necessary for all spam emails to be learned. To adapt to new malicious campaigns quickly, only new types of spam emails should be selected for learning and this can be realized by introducing an active learning scheme into a classifier model. For this purpose, we adopt Resource Allocating Network with Locality Sensitive Hashing (RAN-LSH) as a classifier model with a data selection function. In RAN-LSH, the same or similar spam emails that have already been learned are quickly searched for a hash table in Locally Sensitive Hashing (LSH), in which the matched similar emails located in “well-learned” are discarded without being used as training data. To analyze email contents, we adopt the Bag of Words (BoW) approach and generate feature vectors whose attributes are transformed based on the normalized term frequency-inverse document frequency (TF-IDF). We use a data set of double-bounce spam emails collected at National Institute of Information and Communications Technology (NICT) in Japan from March 1st, 2013 until May 10th, 2013 to evaluate the performance of the proposed system. The results confirm that the proposed spam email detection system has capability of detecting with high detection rate.
Resonance-free low-pass filters for the AC Josephson voltage standard (2006)

We have designed and characterized superconducting integrated circuits for the ac Josephson voltage standard that demonstrate significantly improved performance. The typical circuit consists of an array of superconductor-normal metal-superconductor Josephson junctions, which are placed in a transmission line and biased with a broad-band (dc-to-15 GHz) pulse-drive waveform. Additional low-speed (dc and audio frequency) bias and output leads contain on-chip inductors that act as low-pass filters. The operating margins of the array were improved by adding resistive shunts across these inductors to damp their intrinsic resonances. These resonances had previously degraded the integrity of the broad-band signal driving the array. We present simulations and measurements of these improved circuits that demonstrate no resonances in the range of 0.1-20 GHz. Moreover, the operating margins of the ac Josephson voltage standard were improved.
Generation of a 3D model for human cereblon using comparative modelling (2013)

  Three-dimensional (3D) protein structures provide helpful insights into the molecularassociation of a gene, its purpose also allow efficient drug designing experiments, such as the structure-based design of specific inhibitors. Recently, it has been shown that protein (cereblon) is involved in various tissues and brain and is revealed to be related with mental retardation. After this first report of cereblon (CRBN) involvement, it was necessary to further study this protein. Therefore a 3D structure of cereblon was developed using comparative modeling approach. By comparing the templates-target sequence, a model was created using MODELLER, a program for homology modeling. The accuracy of the predicted structure was checked using Ramachandran plot which showed that the residue falling in the favoured region was 88.4%. Thepredicted cereblon model can be used to understand the pathogenesis of mutations in cereblon that causes adenosine-5'-triphosphate (ATP)-dependent degradation of proteins in memory and learning.   Key words: CRBN, 3D structure, 1M4Y, MODELLER, comparative homology modeling.
Beyond the Antigen Receptor: Editing the Genome of T-Cells for Cancer Adoptive Cellular Therapies (2013)

Recent early stage clinical trials evaluating the adoptive transfer of patient CD8(+) T-cells re-directed with antigen receptors recognizing tumors have shown very encouraging results. These reports provide strong support for further development of the therapeutic concept as a curative cancer treatment. In this respect combining the adoptive transfer of tumor-specific T-cells with therapies that increase their anti-tumor capacity is viewed as a promising strategy to improve treatment outcome. The ex vivo genetic engineering step that underlies T-cell re-direction offers a unique angle to combine antigen receptor delivery with the targeting of cell-intrinsic pathways that restrict T-cell effector functions. Recent progress in genome editing technologies such as protein- and RNA-guided endonucleases raise the possibility of disrupting gene expression in T-cells in order to enhance effector functions or to bypass tumor immune suppression. This approach would avoid the systemic administration of compounds that disrupt immune homeostasis, potentially avoiding autoimmune adverse effects, and could improve the efficacy of T-cell based adoptive therapies.
Combustion imaging from electrical impedance measurements (1996)

The development of stray-immune circuits to measure very small floating capacitances has enabled the technique of electrical capacitance tomography (ECT) to be developed. Burning fuel, for example in an internal combustion engine, produces a high concentration of ions, thus modifying the dielectric constant of the combustion volume. Thus ECT can be applied to produce tomographic images inside a combustion chamber, independent of flame luminosity. However, the major effect of the increase in ion concentration is to increase the conductivity of the volume. The ECT technique has been extended to measure both the change in permittivity and change in conductivity, yielding additional information on the flame composition.
Edge-preserving image decomposition via joint weighted least squares (2015)

Recent years have witnessed the emergence of image decomposition techniques which effectively separate an image into a piecewise smooth base layer and several residual detail layers. However, the intricacy of detail patterns in some cases may result in side-effects including remnant textures, wrongly-smoothed edges, and distorted appearance. We introduce a new way to construct an edge-preserving image decomposition with properties of detail smoothing, edge retention, and shape fitting. Our method has three main steps: suppressing high-contrast details via a windowed variation similarity measure, detecting salient edges to produce an edge-guided image, and fitting the original shape using a weighted least squares framework. Experimental results indicate that the proposed approach can appropriately smooth non-edge regions even when textures and structures are similar in scale. The effectiveness of our approach is demonstrated in the contexts of detail manipulation, HDR tone mapping, and image abstraction.
Lymphangiogenesis and its role in cancer. (2005)

In many tumour types, lymphatic vasculature serves as a major route for tumour metastasis. The dissemination of malignant cells to the regional lymph nodes is an early step in the progression of many solid tumours and is an important determinant of prognosis. Lymphangiogenesis (formation of new lymphatic vessels) is thought to be crucial for cancer cells to metastasise to the regional lymph nodes. However research in this important process has been neglected largely due to the lack of molecular markers specific to the lymphatic endothelium. Recently, several specific markers have been identified including LYVE-1, podoplanin and prox-1. Although the biology of lymphangiogeneis, particularly its regulation, is still far from clear, it is now well established that tumours are lymphangiogenic i.e. they could induce the generation of their own lymphatics and metastasise to the regional lymph nodes. It is thought that the interruption of the main signalling pathways involved in this process could help to prevent lymphatic spread of many tumours. Furthermore, understanding the molecular mechanisms in lymphangiogenesis might help to develop new therapeutic strategies against cancer lymphatic spread. Here, we reviewed the literature in regards to the biology of lymphangiogenesis, its molecular regulation, lymphatic markers and the significance in human solid tumours.
Pax3 induces differentiation of juvenile skeletal muscle stem cells without transcriptional upregulation of canonical myogenic regulatory factors (2010)

Pax3 is an essential myogenic regulator of fetal and embryonic development, but its role in postnatal myogenesis remains a topic of debate. We show that constitutive expression of Pax3 in postnatal, juvenile mouse skeletal muscle stem cells, a subset of the heterogeneous satellite cell pool highly enriched for myogenic activity, potently induces differentiation. This differentiation-promoting activity stands in contrast to the differentiation-inhibiting effects of Pax3 in the commonly used mouse myoblast cell line C2C12. Pax3 mRNA levels in distinct muscles correlate with the rate of myogenic differentiation of their muscle stem cells. Although Pax3 controls embryonic myogenesis through regulation of the canonical myogenic regulatory factors (MRFs) Myf-5, MyoD, myogenin and Mrf4, we find that in postnatal muscle stem cells, ectopic Pax3 expression fails to induce expression of any of these factors. Unexpectedly, overexpression of neither Myf-5 nor myogenin is sufficient to induce differentiation of juvenile stem cells; and knockdown of Myf-5, rather than inhibiting differentiation, promotes it. Taken together, our results suggest that there are distinct myogenic regulatory pathways that control the embryonic development, juvenile myogenesis and adult regeneration of skeletal myofibers.

The Modular Multisensory DLR-HIT-Hand: Hardware and Software Architecture (2008)

This paper presents hardware and software architecture of the newly developed compact multisensory German aerospace research (DLR)-Harbin Institute of Technology (HIT)-Hand. The hand has four identical fingers and an extra degree of freedom for the palm. In each finger, there is a field-programmable gate array (FPGA) for data collection, brushless dc motors for control, and communication is accomplished with palm's FPGA by point-to-point serial communication (PPSeCo). The kernel of the hardware system is a peripheral component interconnect (PCI)- based high-speed floating-point DSP for data processing, and FPGA for high-speed (up to 25 Mb/s) real-time serial communication with the palm's FPGA. In order to achieve high modularity and reliability of the hand, a fully mechatronic integration and analog signals in situ digitalization philosophy is implemented to minimize the dimension and number of the cables (five cables including power supply), and protect data communication from outside disturbances. Furthermore, according to the hardware structure of the hand, a hierarchical software structure has been established to perform all data processing and the control of the hand. It provides basic air position indicator (API) functions and skills to access all hardware resources for data acquisition, computation, and teleoperation. With the nice design of the hand's envelop, the hand looks more like a humanoid.
Evaluation and Updating of the Osiris Expert System for Identification of <i>Escherichia coli</i> β-Lactam Resistance Phenotypes (2005)

Osiris is a video zone size reader for disk diffusion tests that includes a built-in extended expert system (EES). We evaluated the efficacy of the Osiris EES for the identification of beta-lactam susceptibility phenotypes of Escherichia coli isolates. Fifteen beta-lactam agents and three beta-lactam-beta-lactamase inhibitor combinations were tested by the disk diffusion method against 50 E. coli strains with well-characterized resistance mechanisms. The strains were screened for the production of extended-spectrum beta-lactamase (ESBL) by the double-disk synergy test using a disk of amoxicillin-clavulanic acid with disks of the extended-spectrum cephalosporins and aztreonam. Overall, the EES accurately identified the phenotype for 78% of the strains, indicated an inexact phenotype for 17% of the strains, and could not find a matching phenotype for the remaining 5% of the strains. The percentage of correct identification for each resistance mechanism was 100% for inhibitor-resistant TEM and for TEM plus cephalosporinase, 88.9% for TEM and for ESBL, 70.8% for cephalosporinase overproduction, and 25% for oxacillinase. The main cause of discrepancy was the misidentification of oxacillinase as inhibitor-resistant TEM. The conventional double-disk synergy test failed to detect ESBL production in two strains (one producing VEB-1 and one producing CTX-M-14), but synergy between cefepime and amoxicillin-clavulanic acid was visible after the distance between the disks was reduced to 20 mm. After the interpretative guidelines of the EES were updated according to our results, the percentage of correct phenotype identification increased from 78 to 96%.

Optimal braking for impact force reduction using the dynamics of redundant manipulators (2006)

Recently, developers have created a number of manipulators designed to provide physical services to human beings. Collisions between those manipulators and humans or other objects in the environment generate massive impacts, causing injury or limiting execution speed. These collisions are unavoidable, however; therefore it is essential that the force of such impacts be reduced, thus improving safety and task performance. One of the most effective methods to reduce impact force is to decelerate by braking immediately before the collision. In this paper, we propose dynamic acceleration polytope braking (DAPB), a method which is optimal braking to decelerate impact velocity quickly and without varying the direction of motion in redundant manipulators. DAPB uses a dynamic acceleration polytope to represent the acceleration ability, while considering manipulator dynamics to determine braking torque. By adopting DAPB, the velocity at impact can be decelerated faster than by zero-braking, which decelerates all joint velocities to zero; as a result, impact force can be greatly reduced. Moreover, since the path of the impact point does not stray from the initial impact direction, additional dangerous situations could be avoided. Several simulations and experiments are executed to confirm the braking performance of DAPB
Overexpression of TrkB promotes the progression of colon cancer (2010)

Studies have confirmed that TrkB plays important roles in facilitating metastasis in various types of malignant tumors. In the present study, 30 cases of colon cancer and matched non-tumors were examined for the expression of TrkB by Western blot. The expression of TrkB was also examined in 90 colon tumor sections by immunohistochemical methods, and D2-40 staining was used to evaluate the correlation between TrkB expression and lymphatic vessel density. To investigate the effects of TrkB on the progression of colon cancer, siRNA specific for TrkB was transfected into LoVo cells, and proliferation, apoptosis and invasion of transfected cells were examined using MTT [3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide], flow cytometry and Transwell assays, respectively. Our results showed that TrkB was up-regulated in colon tumors compared with the non-tumorous counterparts, and the overexpression of TrkB was closely correlated with lymphatic vessel density (LVD) and metastasis. Inhibition of TrkB by siRNA increased the apoptotic rates of transfected cells, while the numbers of proliferative and invasive cells were decreased. In summary, our data suggest that overexpression of TrkB in colon cancer possibly plays roles in inhibiting apoptosis, promoting proliferation and invasion, facilitating tumor progression by lymphangiogenesis-associated metastasis.
Joining of Single-Crystal Sapphire to Alumina Using Silicate Glasses (2003)

The joining of a sapphire single crystal plate to alumina ceramic tube is fabricated successfully using 34CaO·30Al2O3·36SiO2 glass as an interlayer. This glass showed good adhesion performance to alumina ceramics and sapphire single crystal. The joint with no crack was obtained by heating at 1550°C for 10 min and slow cooling from 1200°C to room temperature. From the thermal shock test, the half of the specimens showed the cracks after quenching from 225°C to 0°C, but all specimens showed no cracks after quenching from 200°C to 0°C. The specimen, composed of alumina tube-sapphire plate-alumina tube showed the comparable bending strength to the specimen composed of alumina tube-alumina tube.

Local and global algorithms for disambiguation to Wikipedia (2024)

Disambiguating concepts and entities in a context sensitive way is a fundamental problem in natural language processing. The comprehensiveness of Wikipedia has made the online encyclopedia an increasingly popular target for disambiguation. Disambiguation to Wikipedia is similar to a traditional Word Sense Disambiguation task, but distinct in that the Wikipedia link structure provides additional information about which disambiguations are compatible. In this work we analyze approaches that utilize this information to arrive at coherent sets of disambiguations for a given document (which we call approaches), and compare them to more traditional (local) approaches. We show that previous approaches for global disambiguation can be improved, but even then the local disambiguation provides a baseline which is very hard to beat.
Conductive Coupling of Split Ring Resonators: A Path to THz Metamaterials with Ultrasharp Resonances (2014)

We report on a novel metamaterial structure that sustains extremely sharp resonances in the terahertz domain. This system involves two conductively coupled split ring resonators that together exhibit a novel resonance, in broad analogy to the antiphase mode of the so-called Huygens coupled pendulum. Even though this resonance is in principle forbidden in each individual symmetric split ring, our experiments show that this new coupled mode can sustain quality factors that are more than one order of magnitude larger than those of conventional split ring arrangements. Because of the universality of the metamaterial response, the design principle we present here can be applied across the entire electromagnetic spectrum and to various metamaterial resonators.
Adenosine Receptors in the Central Nervous System (1995)

Adenosine is present in the brain under physiological conditions and acts on G protein-coupled receptors. Adenosine regulates neurotransmitter release and neuronal firing rate, dopaminergic neurotransmission, glial cell function, and cerebral blood flow. Adenosine is implicated in sleep/wakefulness and protection against ischemic brain damage, epilepsy, and pain.
Lysine production by S-(.BETA.-aminoethyl)-L-cysteine resistant mutants of Candida pelliculosa. (1979)

S-(β-Aminoethyl)-L-cysteine (SAEC), a sulfur analog of L-lysine, significantly inhibited the growth of wild-type strains of Candida species. The growth inhibition of C. pelliculosa de-pended on SAEC concentrations, but L-lysine and L-α-aminoadipate restored growth effectively. SAEC-resistant mutants were induced from the wild-type strain of C. pelliculosa by ultraviolet irradiation and N-methyl-N'-nitro-N-nitrosoguanidine treatment. Almost all resistant mutants excreted some L-lysine into the medium. Lysine excretion increased after repeated mutations. The mutant strain SR-V-1263 extracellularly produced about 2mg/ml of L-lysine after shaking culture for 96 hr. The effect of various factors on lysine accumulation was investigated with strain SR-V-1263. The concentration of extracellular lysine reached a maximum (3.2 mg/ml) in medium containing 2% polypeptone under the experimental conditions.
