Maternal Dietary Intake of Omega-3 Fatty Acids Correlates Positively with Regional Brain Volumes in 1-Month-Old Term Infants (2019)

Maternal nutrition is an important factor for infant neurodevelopment. However, prior magnetic resonance imaging (MRI) studies on maternal nutrients and infant brain have focused mostly on preterm infants or on few specific nutrients and few specific brain regions. We present a first study in term-born infants, comprehensively correlating 73 maternal nutrients with infant brain morphometry at the regional (61 regions) and voxel (over 300 000 voxel) levels. Both maternal nutrition intake diaries and infant MRI were collected at 1 month of life (0.9 ± 0.5 months) for 92 term-born infants (among them, 54 infants were purely breastfed and 19 were breastfed most of the time). Intake of nutrients was assessed via standardized food frequency questionnaire. No nutrient was significantly correlated with any of the volumes of the 61 autosegmented brain regions. However, increased volumes within subregions of the frontal cortex and corpus callosum at the voxel level were positively correlated with maternal intake of omega-3 fatty acids, retinol (vitamin A) and vitamin B12, both with and without correction for postmenstrual age and sex (P < 0.05, q < 0.05 after false discovery rate correction). Omega-3 fatty acids remained significantly correlated with infant brain volumes after subsetting to the 54 infants who were exclusively breastfed, but retinol and vitamin B12 did not. This provides an impetus for future larger studies to better characterize the effect size of dietary variation and correlation with neurodevelopmental outcomes, which can lead to improved nutritional guidance during pregnancy and lactation.
Surface micromachined MEMS tunable VCSEL at 1550 nm with \textgreater 70 nm single mode tuning (2012)

We present surface micro-machined tunable vertical-cavity surface-emitting lasers (VCSELs) operating around 1550nm with tuning ranges up to 100nm and side mode suppression ratios beyond 40 dB. The output power reaches 3.5mW at 1555 nm. The electro-thermal and the electro-statical actuation of a micro electro-mechanical system (MEMS) movable distributed Bragg reflector (DBR) membrane increases/decreases the cavity length which shifts the resonant wavelength of the cavity to higher/lower values. The wavelength is modulated with 200 Hz/120 kHz. Both tuning mechanisms can be used simultaneously within the same device. The newly developed surface micro-machining technology uses competitive dielectric materials for the MEMS, deposited with low temperature plasma enhanced chemical vapor deposition (PECVD), which is cost effective and capable for on wafer mass production.
Characterization and incidence of radiation-induced meningiomas in a brain tumor database (2022)

Abstract Purpose Radiation-induced meningiomas (RIMs) are meningiomas that associated with prior exposure to radiation. Due to the rare occurrence of RIMs, their behavior has not been well described and their incidence has not been reported. This study aims to characterize RIMs and compare the treatment and outcomes of RIMs to those of spontaneous meningiomas (SMs). Methods 1003 patients seen at a single institution with proven or presumed meningiomas were identified from brain tumor-related diagnoses between 2005 and 2015. Chart review positively-identified patients with RIMs and data was collected on initial diagnosis and treatment, meningioma recurrence/progression, histology, and treatments. Results Fifteen RIM patients were identified (66.67% were female and 66.67% were Caucasian). The average age at diagnosis was 43.27 ± 15.06 years. The overall mean latency was 356.27 ± 116.96 months. The mean latency period for the African-American population was 258.4 ± 84.86 months compared to 405.2 ± 100.5 months for the Caucasian population (p = 0.003). The mean number of lesions for males was 1.4 ± 0.89 compared to females which was 2.8 ± 1.40 (p = 0.046). The incidence of RIMs among all meningiomas in our data set was 1.5%, a statistic that has not previously been reported. The 10-year progression-free survival rate and recurrence-free survival rate was 50% and 27%, respectively. 58% of patients treated with radiotherapy were progression-free at 5 and 10 years. Conclusion Radiation remains a rare but important cause of meningioma. These meningiomas have a higher grade histology, require aggressive treatment strategies, and have higher recurrence and progression compared to spontaneous meningiomas.
Solubilization of galactosyltransferase that synthesizes 1,4‐β‐galactan side chains in pectic rhamnogalacturonan I (2002)

beta-1,4-Galactan galactosyltransferase (GT) activity was solubilized from potato microsomal membranes in the presence of 78 mM 3-[(3-cholamidopropyl)dimethylammonio]-1-propanesulphonic acid. The solubilized GT activity transferred 14[C]galactose from UDP-14[C]galactose onto the acceptor-substrates composed of rhamnogalacturonan (RG) with short galactan chains (RG-A, approximately 1.2 MDa, mol% Gal/Rha = 0.7; RG-B, approximately 21 kDa, mol% Gal/Rha = 1.2). However, shorter RG containing short galactan chains (approximately 2 kDa and 1.2 kDa), RG oligomers without galactosyl-residues, galactan, and galactooligomers did not act as acceptor-substrates. Optimal pH for 14[C] incorporation onto RG-A and RG-B was around 5.6 and 7.5, respectively. The 14[C]-labelled products synthesized upon RG-A and RG-B could be digested with a RG specific lyase into smaller RG fragments. 1,4-beta-Endogalactanase could not digest the former product, whereas the latter product was digested to 14[C]galactobiose and 14[C]galactose. This demonstrates that at least two GT activities were solubilized from potato microsomal membranes. One had optimal pH around 5.6 to transfer galactosyl residues onto RG-A, whereas the other had optimal pH around 7.5 to transfer galactosyl residues onto RG-B. Both synthesized galactan attached to the RG backbone of RG-A and RG-B, and the galactan synthesized onto the RG-B acceptor was 1,4-beta-linked.

Antimicrobial coatings against biofilm formation: the unexpected balance between antifouling and bactericidal behavior (2015)

There is a balance between antibacterial and antifouling functions, and the polymer without cationic antibacterial components effectively prevents biofilm formation.
An Image-Based Approach to Visual Feature Space Analysis (2008)

Methods for management and analysis of non-standard data often rely on the so-called feature vector approach. The technique\ndescribes complex data instances by vectors of characteristic numeric values which allow to index the data and to calculate\nsimilarity scores between the data elements. Thereby, feature vectors often are a key ingredient to intelligent data analysis\nalgorithms including instances of clustering, classification, and similarity search algorithms. However, identification of appropriate\nfeature vectors for a given database of a given data type is a challenging task. Determining good feature vector extractors\nusually involves benchmarks relying on supervised information, which makes it an expensive and data dependent process. In\nthis paper, we address the feature selection problem by a novel approach based on analysis of certain feature space images.\nWe develop two image-based analysis techniques for the automatic discrimination power analysis of feature spaces. We evaluate\nthe techniques on a comprehensive feature selection benchmark, demonstrating the effectiveness of our analysis and its\npotential toward automatically addressing the feature selection problem.

New mullite ceramic packages and substrates (2003)

Recent VLSI packaging technology requires high propagation speed, high wiring density and high thermal dissipation. In order to achieve these requirements, ceramic packages need to have a low thermal-expansion coefficient, a low dielectric constant, and a high thermal conductivity. For these purposes, new mullite ceramics have been developed. Their advantages and characteristics are as follows: (1) low dielectric constants (5.4 approximately 7.3 at 1 MHz), which are favorable for the high propagation speed; (2) low thermal expansion coefficients (3.0 approximately 4.5*10/sup -6// degrees C), which permit the direct attachment of a large silicon chip; (3) higher mechanical strength (20 approximately 31 kg/mm/sup 2/) than that for old mullite ceramics; (4) realization of tungsten metallization with a high adhesion strength by using Y/sub 2/O/sub 3/ as an additive; (5) low cost; and (6) ease of processing. The conventional alumina production process can be used for the new ceramic.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

HAMR Adjacent Track Stability in the Presence of a Medium Curie Temperature Distribution (2010)

Evidence of a Curie temperature distribution has been observed in longitudinal media. These results were explained in terms of grain-to-grain variations in composition. Additives are under consideration for FePt HAMR media that may introduce such a distribution into HAMR media. Simple calculations are used to argue that a Curie temperature distribution is unlikely to affect adjacent track aging, but may widen transitions during the write process.

Statistical modeling of DSP-based Hill-climbing MPPT algorithms in noisy environments (2005)

The effect of measurement noise on DSP-based maximum power point tracking (MPPT) algorithms is investigated in this paper. Based on the probabilistic characteristics of noise signals, a statistical model is constructed that allows quantitative analysis of the behavior of such algorithms both during transients and in steady-state. This model is then used to classify tracking problems into those presented by noise, and others resulting from other non-idealities such as measurement bias. It is then used to inspect different noise fighting techniques in order to predict their validity, and to suggest more relevant techniques. The results arrived at are then experimentally verified and confirm the predictions of the statistical model
Natural Variation of the Amino-Terminal Glutamine-Rich Domain in Drosophila Argonaute2 Is Not Associated with Developmental Defects (2010)

The Drosophila argonaute2 (ago2) gene plays a major role in siRNA mediated RNA silencing pathways. Unlike mammalian Argonaute proteins, the Drosophila protein has an unusual amino-terminal domain made up largely of multiple copies of glutamine-rich repeats (GRRs). We report here that the ago2 locus produces an alternative transcript that encodes a putative short isoform without this amino-terminal domain. Several ago2 mutations previously reported to be null alleles only abolish expression of the long, GRR-containing isoform. Analysis of drop out (dop) mutations had previously suggested that variations in GRR copy number result in defects in RNAi and embryonic development. However, we find that dop mutations genetically complement transcript-null alleles of ago2 and that ago2 alleles with variant GRR copy numbers support normal development. In addition, we show that the assembly of the central RNAi machinery, the RISC (RNA induced silencing complex), is unimpaired in embryos when GRR copy number is altered. In fact, we find that GRR copy number is highly variable in natural D. melanogaster populations as well as in laboratory strains. Finally, while many other insects share an extensive, glutamine-rich Ago2 amino-terminal domain, its primary sequence varies drastically between species. Our data indicate that GRR variation does not modulate an essential function of Ago2 and that the amino-terminal domain of Ago2 is subject to rapid evolution.
Improvement of baker's and brewer's yeast by gene technology (1990)

Abstract Polysaccharides such as starch, cellulose or hemicellulose which constitute the largest part of plant biomass are not fermentable by the yeast Saccharomyces cerevisiae. At the moment the conversion of such compounds depends on the addition of enzymes (e.g. α‐amylase, glucoamylase, xylose isomerase, endoglucanase exoglucanase and β‐glucanase) prior to fermentation. Therefore it is of great commercial interest to create new yeast strains which are able to convert polysaccharides of plant biomass directly into fermentable sugars. In a first step we have constructed an amylolytic S. cerevisiae strain which is able to grow on starch as a sole carbon source. This strain was transformed with DNA harbouring the genes for a‐amylase and glucoamylase from Schwanniomyces occidentalis. Both genes are expressed and the gene products are secreted. Since the two S. occidentalis enzymes are especially suitable in brewing, we thus constructed new yeast strains which could be desirable for the production of low carbohydrate beer. The application of an amylolytic baker's yeast in baking could lead to refrainment from a‐amylase enriched flour in certain types of bread manufacturing. The new S. cerevisiae strains excel by high fermentation rates and ethanol tolerance and the newly acquired ability to degrade starch entirely.
A scalable architecture for fully integrated multi-TV tuners (2017)

Silicon TV tuners have recently achieved and surpassed bulky CAN tuners in terms of circuit performance, providing TV manufacturers lower-cost, smaller foot-print, and more reliable solutions. Silicon TV tuners also made packing multiple tuners into a single die or package possible. Multiple tuners are often needed for feature-rich TVs and Set-Top-Boxes with DVR, picture-in-picture and fast channel switching capabilities. Implemented in a 40nm CMOS technology, this paper presents major building blocks for a monolithic dual-tuner with active splitter, tracking filters and output buffers, a compact lowpower VCO based ADC and a local oscillator generation scheme featuring a 17GHz VCO with fractional dividers.
Enhanced Magnetic Field Perturbations and Electric Currents Observed Downstream of the High Power Helicon (2010)

The high power helicon (HPH) is capable of producing a high density plasma (10 10 m ) and directed ion energies greater than 20 eV that continue to increase tens of centimeters downstream of the thruster. In order to understand the coupling mechanism between the helicon antenna and the plasma outside the immediate source region, measurements were made in the plasma plume downstream from the thruster of the propagating wave magnetic field and the perturbation of the axial bulk field using a type ‘R’ helicon antenna. This magnetic field perturbation (DB) peaks at more than 15 G in strength downstream of the plasma source, and is 3–5 times larger than those previously reported from HPH. Taking the curl of this measured magnetic perturbation and assuming azimuthal symmetry suggests that this magnetic field is generated by a (predominantly) azimuthal current ring with a current density on the order of tens of kA m . At this current density the diamagnetic field is intense enough to cancel out the B0 axial magnetic field near the source region. The presence of the diamagnetic current is important as it demonstrates modification of the vacuum fields well beyond the source region and signifies the presence of a high density, collimated plasma stream. This diamagnetic current also modifies the propagation of the helicon wave, which facilitates a better understanding of coupling between the helicon wave and the resultant plasma acceleration.

Type Synthesis of Compliant Mechanisms Employing a Simplified Approach to Segment Type (1994)

Abstract The formulation of design procedures for rigid-body mechanisms has benefited from the application of type-synthesis techniques. Therefore, with modifications to allow for inclusions of compliance, type synthesis is seen as a useful tool in the design of compliant mechanisms. Previous efforts have developed methods that result in a large number of possible design solutions to a given problem. This paper deals primarily with the development of a simplified compliant-mechanism type-synthesis methodology that limits the number of design solutions considered. The techniques are derived by modifying existing compliant mechanism type-synthesis techniques to yield a simpler model with greater pragmatic value.
Genomic analysis of Leptospira interrogans serovar Paidjan and Dadas isolates from carrier dogs and comparative genomic analysis to detect genes under positive selection (2019)

L. interrogans serovar Paidjan strain CUDO5 and serovar Dadas strain CUDO8 had close genetic relatedness as analyzed by SNPs phylogeny. They contained genes with established roles in acute and chronic leptospirosis. The rfb locus in both serovars showed gene variation associated with sugar biosynthesis. Positive selection analysis indicated that genes encoding factors involved in motility, temperature adaptation, and iron acquisition were under strong positive selection in L. interrogans. These may be associated with adaptation in the early stages of infection.
Nueva generación de vacunas antimeningococica basadas en vesículas de membrana externa (2009)

With the development of conjugate vaccines, Neisseria meningitidis serogroup B (MenB) will remain the major cause of meningitis, as it is not covered by vaccination. In order to develop a vaccine able to confer a broad cross-protection against invasive MenB strains, we have developed a new generation of outer-membrane vesicles (OMVs) based on the over-expression of well conserved minor outer membrane proteins (OMPs) and the presence of high percentage of detoxified LOS.
Year in review 2012: Critical Care - nephrology (2013)

We summarize original research in the field of critical care nephrology accepted or published in 2012 in Critical Care and, when considered relevant or directly linked to this research, in other journals. Three main topics have been identified for a rapid overview: acute kidney injury, detailed in some pathogenetic and epidemiological aspects; fluid overload as a predictor of mortality both in acute kidney injury and renal replacement therapy (RRT) patients; and RRT, evaluating some features of citrate anticoagulation and describing the effects of RRT modalities or timing on survival.
Numerical Solution of Laminar Boundary Layer Flow About a Rotating Sphere in an Axial Stream (1985)

A finite-difference scheme is developed for solving the boundary layer equations governing the laminar flow about a rotating sphere which is subjected to a uniform stream in the direction of the axis of rotation. Numerical results are presented for the meridional and azimuthal velocities and for the wall-shear-stress components. Also, the angle at which the meridional velocity gradient normal to the wall vanishes is given at values of the parameter Ta/Re2 ranged from zero (the stationary sphere case) to 10000. As compared with the momentum integral technique of Schlichting [8], the present scheme succeeded in obtaining solutions for very considerably larger values of the parameter Ta/Re2.
