Photochemically Machined, Glass Ceramic, Optical Fiber Interconnection Components (1989)

An optical fiber array interconnection substrate for computer applications was dgveloped based around a photomachinable glass-ceramic material having the trade name Fotofore% Devices incorporating up to 32 fibers on a single chip were shown to be possible, and the material was demonstrated to be patternable with accuracies approaching single crystal silicon. The glass-ceramic material has several advantages over silicon in that it is less brittle, can be easily loaded with fibers, and can be assembled using UV curable epoxies.
Antibody Reactivity Against Human and Guinea Pig Tissue Transglutaminase in Children with Celiac Disease (2000)

Our results provide additional support to the concept that anti-tTG IgA antibodies can be used as a highly discriminatory serologic marker for celiac disease and that measurements of these autoreactive antibodies may in the future be used as an alternative to the EMA test.
Real-time computation by n-dimensional iterative arrays of finite-state machines (1966)

An n-dimensional iterative array of finitestate machines (abbreviated nD) is a special type of real-time tape acceptor. The principal results are as follows: 1. nD's have equivalent forms With simplified stencils and length k encodings of the input alphabet. 2. The set of palindromes and the set of tapes of the form ττ are accepted by 1D's. 3. The sets of tapes accepted by nD's are a Boolean algebra. 4. The sets of tapes accepted by nD's are not closed under multiplication or reflection. 5. There exists a simple phrase-structure language not accepted by any nD in any dimension n. 6. The computing power of the class of nD's is strictly less than the computing power of the class of (n+1)D's.
Measurement-based equivalent circuit model for ferrite beads (2009)

An equivalent circuit simulation model for ferrite beads is presented. Linear and nonlinear lumped frequency-independent R, L and C circuit elements are used to model the DC-bias dependency of the frequency response. An optimization scheme has been developed to extract the nominal component values and the coefficients of the nonlinear functions from the measured small-signal frequency responses at 1 MHz - 3 GHz and at several bias currents. Both APLAC and ELDO models for ferrites from three manufacturers have been extracted.
PapersLocal treatments for cutaneous warts: systematic reviewCommentary: Systematic reviewers face challenges from varied study designs (2002)

Reviewed trials of local treatments for cutaneous warts were highly variable in methods and quality, and there was a paucity of evidence from randomised, placebo controlled trials on which to base the rational use of the treatments. There is good evidence that topical treatments containing salicylic acid have a therapeutic effect and some evidence for the efficacy of dinitrochlorobenzene. Less evidence was found for the efficacy of all the other treatments reviewed, including cryotherapy.
Cyclomatic complexity and the year 2000 (1996)

The year 2000 problem is omnipresent, fast approaching, and will present us with something we're not used to: a deadline that can't slip. It will also confront us with two problems, one technical, the other managerial. My cyclomatic complexity measure, implemented using my company's tools, can address both of these concerns directly. The technical problem is that most of the programs using a date or time function have abbreviated the year field to two digits. Thus, as the rest of society progresses into the 21st century, our software will think it's the year 00. The managerial problem is that date references in software are everywhere; every line of code in every program in every system will have to be examined and made date compliant. In this article, I elaborate on an adaptation of the cyclomatic complexity measure to quantify and derive the specific tests for date conversion. I originated the use of cyclomatic complexity as a software metric. The specified data-complexity metric is calculated by first removing all control constructs that do not interact with the referenced data elements in the specified set, and then computing cyclomatic complexity. Specifying all global data elements gives an external coupling measure that determines encapsulation. Specifying all the date elements would quantify the effort for a year-2000 upgrade. This effort will vary depending on the quality of the code that must be changed.
The Catalytically Active Tyrosine Residues of Both SPO11-1 and SPO11-2 Are Required for Meiotic Double-Strand Break Induction in <i>Arabidopsis</i> (2007)

SPO11, a homolog of the subunit A of the archaebacterial topoisomerase VI, is essential for double-strand break (DSB)-induced initiation of meiotic recombination. In contrast with single homologs in animals and yeasts, three homologs are present in Arabidopsis thaliana and other higher plants. Whereas At SPO11-3 is involved in somatic endoreduplication, At SPO11-1 and, as recently shown, At SPO11-2 are essential for the initiation of meiotic recombination. Further defining the role of At SPO11-2, we were able to demonstrate that it is required for proper chromosome segregation, as its loss resulted in aneuploidy in the surviving progeny. The double mutant spo11-1 spo11-2 does not differ phenotypically from the single mutants, indicating that both proteins are required for the same step. Contrary to the observations for the At rad51-1 single mutant, the combination of spo11-2 and rad51-1 did not lead to chromosome fragmentation, indicating that SPO11-2, like SPO11-1, is required for DSB induction. As the meiotic phenotype of both single SPO11 mutants can be reversed by complementation using the full-length genes but not the same constructs mutated in their respective catalytically active Tyr, both proteins seem to participate directly in the DNA breakage reaction. The active involvement of two SPO11 homologs for DSB formation reveals a striking difference between plants and other eukaryotes in meiosis.
Divergent tissue-specific and developmental expression of receptors for glucagon and glucagon-like peptide-1 in the mouse (1994)

Proglucagon mRNA transcripts are transcribed in the pancreas, bowel, and brain, after which posttranslational processing results in the liberation of a different profile of biologically active peptides in each tissue. The receptors for two of these peptides, glucagon and glucagon-like peptide-1 (GLP-1), have recently been identified, but only limited information is available concerning the tissue- and age-specific distribution of these receptors in vivo. We have investigated the expression of these receptors in the mouse using a combination of Northern blot analysis and reverse transcription-polymerase chain reaction. DNA sequence analysis of a partial mouse glucagon receptor cDNA demonstrated a high degree of sequence conservation across rodent species. Glucagon receptor mRNA transcripts were detectable by Northern blotting in poly(A)+ RNA from liver and kidney. Reverse transcription-polymerase chain reaction also detected glucagon receptor mRNA transcripts in both fetal and adult pancreas and lung, jejunum, and ileum, but not in the large intestine. In contrast, mRNA transcripts for the GLP-1 receptor were detected in both small and large intestine as well as in pancreas, liver, lung, and kidney. Both glucagon and GLP-1 receptor mRNA transcripts were identified in different regions of the fetal and adult mouse brain, but the relative levels of GLP-1 receptor mRNA transcripts were much greater in the central nervous system. Furthermore, regulation of the GLP-1 receptor (but not the glucagon receptor) gene in the brain resembled the pattern of region-specific gene expression recently defined for the mouse proglucagon gene. Taken together, these studies define novel sites for both glucagon and GLP-1 receptor gene expression in the mouse and suggest that different regulatory mechanisms have evolved for tissue-specific and developmental control of receptor gene expression.

Constant-bandwidth current mode operational amplifier (1991)

A current mode operational amplifier with a low impedance output for feedback connection is proposed and analysed theoretically. It is found to have a constant bandwidth independent of the gain in a closed loop configuration. This property is due to the loop gain independent of the closed loop gain. The amplifier is shown to be composed of a current conveyor input stage and another current conveyor output stage. Experimental results are presented to verify the constant bandwidth performance, and it is concluded that the proposed configuration is suitable for high frequency current mode amplifiers.

Hilos, cables y conectores: los humildes componentes en la electrónica (2003)

Siempre he creído que son los detalles más insignificantes los que determinan que las cosas funcionen o no. Por otro lado, es de todos conocido el hecho de que la principal causa de los defectos y averías en nuestras máquinas es el deterioro, y por esto el mal conexionado de los sistemas está en el origen de muchos fallos. Con todo ello, un punto fundamental a la hora de implementar cualquier equipo es las consideraciones que hagamos sobre los cableados a realizar y los conectores a emplear. Esta es la razón que me ha llevado a escribir el siguiente artículo, donde expongo, de manera muy superficial, qué materiales aislantes recubren los cables, qué es un conductor y qué es un cable, cómo influye la densidad de corriente en la sección a emplear y que tipo de conductores nos encontraremos en el mercado. Por último se tratará el tema de los conectores.
Long‐term course of restless legs syndrome in dialysis patients after kidney transplantation (2002)

Restless legs syndrome (RLS) is a common cause of sleep disturbance and is frequently experienced by hemodialysis patients. Factors triggering the disease in uremia have not yet been identified. To our knowledge, the course of RLS symptoms after kidney transplantation has not been investigated systematically. We investigated the clinical long-term course of RLS in hemodialysis patients who underwent kidney transplantation. Patients were given a standardized questionnaire three times: at baseline, and twice after their kidney transplants. The severity of RLS was rated by the patients (0 =no symptoms, 10 = very severe symptoms). The description of the final outcome was based on the last follow-up visit. Eleven of 64 hemodialysis patients with RLS received a transplant (5 men, 6 women; severity of RLS at baseline, 7.8 +/- 0.7 [mean +/- SEM]). In all patients, RLS symptoms disappeared within 1 to 21 days after transplantation. At follow-up visits, 4 patients whose transplanted kidneys still functioned well were still free of RLS symptoms up to the longest follow-up period of 9 years. In 3 other patients, RLS symptoms gradually reappeared (severity, 1 +/- 0). In 3 of 11 patients, the transplant failed and RLS symptoms reoccurred within 10 days to 2 months (severity, 7.3 +/- 2.6). RLS symptoms reoccurred in 1 patient with failure of the transplant but disappeared again after a second, successful transplant. Kidney transplantation has a strong and positive influence on RLS symptoms in hemodialysis patients. Hemodialysis patients can expect a substantial improvement of RLS symptoms after a successful kidney transplant.

Characterization of the 4-Carboxy-4-Hydroxy-2-Oxoadipate Aldolase Gene and Operon Structure of the Protocatechuate 4,5-Cleavage Pathway Genes in <i>Sphingomonas paucimobilis</i> SYK-6 (2002)

The protocatechuate (PCA) 4,5-cleavage pathway is the essential metabolic route for degradation of low-molecular-weight products derived from lignin by Sphingomonas paucimobilis SYK-6. In the 10.5-kb EcoRI fragment carrying the genes for PCA 4,5-dioxygenase (ligAB), 2-pyrone-4,6-dicarboxylate hydrolase (ligI), 4-oxalomesaconate hydratase (ligJ), and a part of 4-carboxy-2-hydroxymuconate-6-semialdehyde dehydrogenase (ligC), we found the ligK gene, which encodes 4-carboxy-4-hydroxy-2-oxoadipate (CHA) aldolase. The ligK gene was located 1,183 bp upstream of ligI and transcribed in the same direction as ligI. We also found the ligR gene encoding a LysR-type transcriptional activator, which was located 174 bp upstream of ligK. The ligK gene consists of a 684-bp open reading frame encoding a polypeptide with a molecular mass of 24,131 Da. The deduced amino acid sequence of ligK showed 57 to 88% identity with those of the corresponding genes recently reported in Sphingomonas sp. strain LB126, Comamonas testosteroni BR6020, Arthrobacter keyseri 12B, and Pseudomonas ochraceae NGJ1. The ligK gene was expressed in Escherichia coli, and the gene product (LigK) was purified to near homogeneity. Electrospray-ionization mass spectrometry indicated that LigK catalyzes not only the conversion of CHA to pyruvate and oxaloacetate but also that of oxaloacetate to pyruvate and CO(2). LigK is a hexamer, and its isoelectric point is 5.1. The K(m) for CHA and oxaloacetate are 11.2 and 136 micro M, respectively. Inactivation of ligK in S. paucimobilis SYK-6 resulted in the growth deficiency of vanillate and syringate, indicating that ligK encodes the essential CHA aldolase for catabolism of these compounds. Reverse transcription-PCR analysis revealed that the PCA 4,5-cleavage pathway genes of S. paucimobilis SYK-6 consisted of four transcriptional units, including the ligK-orf1-ligI-lsdA cluster, the ligJAB cluster, and the monocistronic ligR and ligC genes.
An improved active learning sparse least squares support vector machines for regression (2015)

Recently, active learning sparse least squares support vector machines (AL-LSSVM) was put forward to solving the sparseness problem of least squares support vector machine, which demonstrates better sparseness and robustness than Sukens' algorithm in removing the similar samples and solving the problem of heteroscedasticity. However, there are several problems to consider. In choosing support vectors, the approximation problem was solved by recursively selecting data with a big error in the previous process. And the performance will be not predicted to the best after the data has been selected. As a result, the process of selecting is longer and instability, its performance is sensitive to the choosing data. Therefore, an improved active learning least squares support vector machines (IAL-LSSVM) is introduced, with selecting samples based on sorted performance spectrum, which gradually chooses the support sample with the best performance after select the sample for the next iteration. In order to prove the efficacy and feasibility of our proposed IAL-LSSVM, some experiments are done comparing to AL-LSSVM. And they are all favorable for our viewpoints. That is, the IAL-LSSVM has better sparseness and robustness than AL-LSSVM.
Toward Large-Scale Face Recognition Using Social Network Context (2010)

Personal photographs are being captured in digital form at an accelerating rate, and our computational tools for searching, browsing, and sharing these photos are struggling to keep pace. One promising approach is automatic face recognition, which would allow photos to be organized by the identities of the individuals they contain. However, achieving accurate recognition at the scale of the Web requires discriminating among hundreds of millions of individuals and would seem to be a daunting task. This paper argues that social network context may be the key for large-scale face recognition to succeed. Many personal photographs are shared on the Web through online social network sites, and we can leverage the resources and structure of such social networks to improve face recognition rates on the images shared. Drawing upon real photo collections from volunteers who are members of a popular online social network, we asses the availability of resources to improve face recognition and discuss techniques for applying these resources.
Suppression of Inhibit Cell <I>V</I><SUB>th</SUB> Disturbance in Three Dimensional Stack NAND Flash Memory (2013)

In this work, we characterize inhibit cell Vth disturbance related to the 3D stack NAND channel boosting during program and propose a new method to suppress the hot carrier injection related disturbance. The hot-carrier effect on program inhibit string is arisen from the potential difference between the highly boosted channel and turned-off bit line (BL) selection device which is directly connected to the boosted channel. In the proposed method by us, electrons are flown to the channel with the edge word line (WL) biased initially at a Vpass before channel cut-off. Then the highly boosted channel potential decreases to some extent due to the re-distribution of excess electrons after channel cut-off. Consequently, when we apply the proposed method, large disturbed cell Vth in the inhibit strings for high Vpass is well controlled by suppressing hot-carrier generation, which leads to the higher pass voltage during both program and read operations while keeping reliable cell operations for 3D stack NAND.
Detoxification of a Mixture of Aliphatic Chlorinated Hydrocarbons in a Fixed-Bed Bioreactor: Continuous On-line Monitoring via an Attenuated Total Reflection-Fourier Transform Infrared Sensor (1999)

A methanogenic microbial community immobilised on an inert carrier was acclimated to a mixture of chlorinated aliphatic hydrocarbons in a bioreactor used for their detoxification. The mixture contained trichloroethylene (TCE), tetrachloroethylene (PCE), carbon tetrachloride (CT) and hexachlorobutadiene (HCB). An attenuated total reflection-Fourier transform infrared (ATR-FTIR) optical sensor was developed for continuous on-line measurements of the toxic compounds in the dechlorinating bioreactor. The sensor consisted of an ATR internal reflection element (IRE) coated with an extracting polymer which was continuously enriched with the toxic compounds. The bioprocess was monitored through the sensor, which was coupled permanently to the bioreactor, over a period of three days of continuous operation. The sensor tracked the progression of absorbance spectra over time in a non-invasive manner. The concentration of organochlorine compounds in the bioreactor was predicted from the absorbance spectra using a partial least squares (PLS) calibration model which was developed for all components simultaneously. The accuracy and reproducibility of this ATR-FTIR sensor was tested by checking the spectra-based concentration values of the toxic analytes in the bioreactor effluents against off-line gas chromatography (GC) measurements. This novel sensor is useful for routine continuous on-line monitoring of the dechlorinating bioreactor.
Synthesis, Structure, and Spectroscopic Properties of Gold(I)−Carbene Complexes (1999)

A series of gold(I)−carbene complexes of the type [Au(R2-bimy)L] (R = Et, Me; bimy = benzimidazol-2-ylidene; L = Cl, Br, I, bimy, thiophenolate, phenylacetylide) have been prepared. These carbene complexes are luminous in acetonitrile solution and in the solid state with long lifetimes at room temperature. Multiple emissions have been observed for different R and L. The crystal structure of [Au(Me2-bimy)Cl] shows a relatively short intermolecular AuI−AuI contact of 3.1664(10) Å and an intermolecular ring π−π interaction with a ring−ring distance of 3.45 Å. The structure of [Au(Et2-bimy)Cl], however, shows only intermolecular ring−ring interactions with a distance of 3.53 Å. Crystal structure data suggest that bimy is a high-trans-influence ligand.
