Holograms recording with pulsed laser on diazonaphthoquinone-novolac-based photoresists and their nanocomposites (2014)

Direct write digital holography technique (DWDH) using a single 440-nm pulsed laser exposure has been proposed to record master holograms on commercially available positive-tone photoresist systems based on a mixture of diazonaphthoquinone and novolac resin (DNQ-novolac) of different thicknesses. The DNQ-novolac nanocomposite doped with copper nanoparticles (CuNPs) films was also used. The method for numerical evaluation of hologram quality based on reflected beam diffraction intensity measurements was proposed and verified. It was found that all investigated photoresist nanocomposites were sensitive enough to record holographic structures at low single pulse laser exposures (from 3.3 to 18.0 mJ/cm2). Moreover, doping DNQ-novolac nanocomposite with CuNPs s increases its sensitivity to pulsed laser exposure by more than 30%. The potential of single pulsed laser exposures to record high quality master holograms on commercially available and metal nanoparticles doped photoresists with at least five times lower exposures values as compared to the continuous-wave laser exposures usually used to expose photoresist materials in holographic applications, opens the possibility to use pulsed lasers for quick master-originals origination for embossed holograms applying a DWDH technique or analog methods.
Molecular marker diversity of SCN-resistant sources in soybean (2006)

Soybean cyst nematode (SCN) (Heterodera glycines Ichinohe; HG) is one of the most destructive pests of soybean (Glycine max (L.) Merr.) in the United States. Over 100 SCN-resistant accessions within the USDA Soybean Germplasm Collection have been identified, but little is known about the genetic diversity of this SCN-resistant germplasm. The objective of this research was to evaluate the genetic variation and determine the genetic relationships among SCN-resistant accessions. One hundred twenty-two genotypes were evaluated by 85 simple sequence repeat (SSR) markers from 20 linkage groups. Non-hierarchical (VARCLUS) and hierarchical (Ward's) clustering were combined with multidimensional scaling (MDS) to determine relationships among tested lines. The 85 SSR markers produced 566 allelic fragments with a mean polymorphic information content (PIC) value of 0.35. The 122 lines were grouped into 7 clusters by 2 different clustering methods and the MDS results consistently corresponded to the assigned clusters. Assigned clusters were dominated by genotypes that possess one or more unique SCN resistance genes and were associated with geographical origins. The results of analysis of molecular variance (AMOVA) showed that the variation differences among clusters and individual lines were significant, but the differences among individuals within clusters were not significant.

Brain-computer interface controlled robotic gait orthosis (2013)

These results provide preliminary evidence that restoring brain-controlled ambulation after SCI is feasible. Future work will test the function of this system in a population of subjects with SCI. If successful, this may justify the future development of BCI-controlled lower extremity prostheses for free overground walking for those with complete motor SCI. Finally, this system can also be applied to incomplete motor SCI, where it could lead to improved neurological outcomes beyond those of standard physiotherapy.
Cytoskeletal dynamics in rabbit synovial fibroblasts: II. Reformation of stress fibers in cells rounded by treatment with collagenase‐lnducing agents (1990)

Modulation of the synthesis and secretion of extracellular matrix proteins and matrix-degrading metalloproteases by rabbit synovial fibroblasts is an important model system for studying the control of tissue-specific gene expression. Induction of collagenase expression is correlated with changes in cell shape and actin filament distribution, but the role of the cellular cytoskeleton in the sustained synthesis and secretion of metalloproteases has not been closely examined. When cells were allowed to respread after rounding by trypsin or cytochalasin, two known metalloprotease inducers, reformation of stress fibers was observed within 2 h in the presence of serum. In the absence of serum, trypsin-treated cells did not respread substantially, even after 24 h in culture. In contrast, cytochalasin-treated cells recovered almost as rapidly in the absence as in the presence of serum, showing reformation of well-formed microfilament bundles within 30 min of drug removal, especially at the spreading cell edges. High resolution electron-microscopic views of detergent-extracted cytoskeletons confirmed the rapid rebundling of peripheral microfilaments. Acrylamide-treated cells fell between these two extremes, spreading slowly in the absence of serum, but almost as rapidly as cytochalasin-treated cells in its presence. Reestablishment of normal intermediate filament distribution generally lagged slightly behind actin for all treatments, and intermediate filaments always appeared to spread back into the cellular cytoplasm within the confines of the reforming peripheral microfilament bundles. No obvious interaction between these two cytoskeletal elements was observed after any treatment, and no specific role for intermediate filaments in modulating gene expression in these cells is suggested by these results. The serum dependence displayed after trypsin or acrylamide treatment may be due to the disturbances in fibronectin synthesis observed in these cells and is consistent with evidence that both induction and sustained expression of matrix-degrading metalloprotease may involve signals transduced through plasma membrane matrix receptors (integrins).
The pyruvate kinase (PK) to hexokinase enzyme activity ratio and erythrocyte PK protein level in the diagnosis and phenotype of PK deficiency (2020)

Diagnosis of pyruvate kinase deficiency (PKD), the most common cause of hereditary non-spherocytic haemolytic anaemia, remains challenging in routine practice and no biomarkers for clinical severity have been characterised. This prospective study enrolled 41 patients with molecularly confirmed PKD from nine North American centres to evaluate the diagnostic sensitivity of pyruvate kinase (PK) enzyme activity and PK:hexokinase (HK) enzyme activity ratio, and evaluate the erythrocyte PK (PK-R) protein level and erythrocyte metabolites as biomarkers for clinical severity. In this population not transfused for ≥90 days before sampling, the diagnostic sensitivity of the PK enzyme assay was 90% [95% confidence interval (CI) 77-97%], whereas the PK:HK ratio sensitivity was 98% (95% CI 87-100%). There was no correlation between PK enzyme activity and clinical severity. Transfusion requirements correlated with normalised erythrocyte ATP levels (r = 0·527, P = 0·0016) and PK-R protein levels (r = -0·527, P = 0·0028). PK-R protein levels were significantly higher in the never transfused [median (range) 40·1 (9·8-73·9)%] versus ever transfused [median (range) 7·7 (0·4-15·1)%] patients (P = 0·0014). The PK:HK ratio had excellent sensitivity for PK diagnosis, superior to PKLR exon sequencing. Given that the number of PKLR variants and genotype combinations limits prognostication based on molecular findings, PK-R protein level may be a useful prognostic biomarker of disease severity and merits further study.
Targeting by AutophaGy proteins (TAG): Targeting of IFNG-inducible GTPases to membranes by the LC3 conjugation system of autophagy (2016)

LC3 has been used as a marker to locate autophagosomes. However, it is also well established that LC3 can localize on various membranous structures other than autophagosomes. We recently demonstrated that the LC3 conjugation system (ATG7, ATG3, and ATG12-ATG5-ATG16L1) is required to target LC3 and IFNG (interferon, gamma)-inducible GTPases to the parasitophorus vacuole membrane (PVM) of a protist parasite Toxoplasma gondii and consequently for IFNG to control T. gondii infection. Here we show that not only LC3, but also its homologs (GABARAP, GABARAPL1, and GABARAPL2) localize on the PVM of T. gondii in a conjugation-dependent manner. Knockout/knockdown of all LC3 homologs led to a significant reduction in targeting of the IFNG-inducible GTPases to the PVM of T. gondii and the IFNG-mediated control of T. gondii infection. Furthermore, when we relocated the ATG12-ATG5-ATG16L1 complex, which specifies the conjugation site of LC3 homologs, to alternative target membranes, the IFNG-inducible GTPases were targeted to the new target membranes rather than the PVM of T. gondii. These data suggest that the localization of LC3 homologs onto a membrane by the LC3 conjugation system is necessary and sufficient for targeting of the IFNG-inducible GTPases to the membrane, implying Targeting by AutophaGy proteins (TAG). Our data further suggest that the conjugation of ubiquitin-like LC3 homologs to the phospholipids of membranes may change the destiny of the membranes beyond degradation through lysosomal fusion, as the conjugation of ubiquitin to proteins changes the destiny of the proteins beyond proteasomal degradation.
A case for embedded optical communications (2008)

The weight of a vehiclepsilas data and power cables will increase due to increased need for electronic components that are spread throughout the craft. Advances in lasing and optical fiber systems present an opportunity for designers to embed optics into the vehiclepsilas subsystems to reduce interconnect weight because glass is approximately frac14 the weight of copper. This paper presents four types (levels) of optical integration showing the respective weight reducing benefits for several subsystems of the Apache Longbow helicopter. Systematic examinations of a subset of the Apachepsilas systems indicate weight reductions will vary based upon the level of integration: the interconnect weight could increase (studies show -121% change) or decrease dramatically (studies show 89% weight improvement). Thus, this work demonstrates that while benefits could be large, careless introduction of optical technology into a vehicle like the Apache can have diminished or even detrimental effects.
(E)-1-[(2-Chlorophenyl)methyleneamino]guanidinium chloride (2007)

The title compound, C8H10ClN4+·Cl−, was prepared by the condensation reaction of 2-chloro­benzaldehyde with amino­guanidine hydro­chloride. The guanidinium group is twisted by 21.88 (17)° from the 2-chloro­phenyl ring and the C=N group has E geometry. The chloride ions are involved in inter­molecular hydrogen bonds with the H atoms of the amino­guanidinium ion.
Toward cloud-ready transport networks (2012)

Operators are challenged by the new cloud services, which can modify current traffic pattern. This talk presents the Telefonica I+D view on the evolution towards a transport network ready to support cloud services. It explains the reasons why current transport networks are not efficiently design for a cloud environment and it describes the architecture for a cloud-ready network. To show the feasibility of such cloud-ready network, experimental validations are presented to show the concepts of a cloud-ready transport network.
The structure of a birnavirus polymerase reveals a distinct active site topology (2007)

Single-subunit polymerases are universally encoded in both cellular organisms and viruses. Their three-dimensional structures have the shape of a right-hand with the active site located in the palm region, which has a topology similar to that of the RNA recognition motif (RRM) found in many RNA-binding proteins. Considering that polymerases have well conserved structures, it was surprising that the RNA-dependent RNA polymerases from birnaviruses, a group of dsRNA viruses, have their catalytic motifs arranged in a permuted order in sequence. Here we report the 2.5 A structure of a birnavirus VP1 in which the polymerase palm subdomain adopts a new active site topology that has not been previously observed in other polymerases. In addition, the polymerase motif C of VP1 has the sequence of -ADN-, a highly unusual feature for RNA-dependent polymerases. Through site-directed mutagenesis, we have shown that changing the VP1 motif C from -ADN- to -GDD- results in a mutant with an increased RNA synthesis activity. Our results indicate that the active site topology of VP1 may represent a newly developed branch in polymerase evolution, and that birnaviruses may have acquired the -ADN- mutation to control their growth rate.
Association Between I2 Binding Sites and Monoamine Oxidase‐B Activity in Platelets (2003)

An I(2) imidazoline binding site on monoamine oxidase-B (MAO-B) is known to be encoded by a noncatalytic part of the enzyme, different from that which recognizes mechanism-based inhibitors. Herein, the relationship between I(2)-imidazoline binding sites and MAO-B activity has been assessed using a semi-purified source of MAO-B: platelet mitochondrial membranes. A positive correlation between I(2) sites and MAO-B activity was observed (r = 0.61, P = 0.0016) among 24 human subjects. Nevertheless, the variance in MAO-B activity cannot be completely accounted for in relation to I(2) sites. Therefore, I(2) density and MAO-B activity are only weakly correlated in platelets.
A Catalytic and Stereoselective Glycosylation with Glucopyranosyl Fluoride by Using Various Protic Acids (2001)

Abstract A catalytic and stereoselective glycosylation with glucosyl fluoride was effectively performed by using a catalytic amount of various protic acids. When the glycosylation was carried out, for example, using perchloric acid (HClO4) in diethyl ether (Et2O), the major products were α-glycosides while β-stereoselectivity was observed when tetrakis(pentafluorophenyl)boric acid [HB(C6F5)4] was used in a mixed solvent of trifluoromethylbenzene (BTF)–pivalonitrile (tBuCN) = (5:1). The stereoselectivity was controlled by not only the effect of solvent but also by the nature of counter anion of the catalyst such as B(C6F5)4− or ClO4−.
π‐Expanded Borazine: An Ambipolar Conjugated B–π–N Macrocycle (2012)

Staying at a B ′N′ B: A highly symmetric cyclic structure in which N donor and B acceptor sites are alternating (see picture) is found for the first ambipolar π-conjugated B–N macrocycle. The donor–π–acceptor arrangement results in mutual interactions between B and N and a pronounced solvatochromic effect on the emission. The strong luminescence in solution also lends itself to use in anion recognition.
Optical coherence tomography for imaging the vulnerable plaque (2006)

While our understanding of vulnerable coronary plaque is still at an early stage, the concept that certain types of plaques predispose patients to developing an acute myocardial infarction continues to be at the forefront of cardiology research. Intracoronary optical coherence tomography (OCT) has been developed to both identify and study these lesions due to its distinct resolution advantage over other imaging modalities. We review clinical research conducted at the Massachusetts General Hospital over the past five years to develop, validate, and utilize this technology to improve our understanding of vulnerable plaque. Our results show that intracoronary OCT may be safely conducted in patients and that it provides abundant information regarding plaque microscopic morphology, which is essential to the identification and study of high-risk lesions. Even though many basic biological, clinical, and technological challenges must be addressed prior to widespread use of this technology, the unique capabilities of OCT ensure that it will have a prominent role in shaping the future of cardiology.
The effect of Er3+-ion concentration on the Er3+:4I13/2 → 4I15/2transition in tellurite glasses (2004)

The effect of Er3+ concentration on the Er3+ : 4I13/2 → 4I15/2 emission in tellurite glasses has been investigated. The full width at half-maximum increased with the increasing concentration of Er2O3 in tellurite glasses. The effect of local structure of Er3+ ions and related spectroscopic changes are taken into account to explain the line broadening. Inhomogeneous broadening due to the distribution of crystal field around the Er3+ ion has little effect on the absorption spectra. Highly efficient energy trapping between the ions was identified from the time-resolved analysis of the fluorescence decay and is found to be responsible for the extended lifetime at intermediate concentrations of Er3+ ions in tellurite glasses. The effect of temperature on spectral line shape has been determined for analysing the contribution of Boltzmann population on line broadening. The increased population of the overlying Stark sublevels at the 4I13/2 energy level via direct pumping and/or interaction between Er3+ ions were also found to be significant for enhancement in spectral line shape at higher concentrations of Er3+ ions in tellurite glasses. It was observed that at higher concentrations of Er3+ ions in glass also enhance the local symmetry of ions, which is apparent from the absorption band of the Er3+ : 4I15/2 → 2H11/2 hypersensitive transition.
Atomic layer epitaxy (1986)

Atomic layer epitaxy (ALE) is not so much a new technique for the preparation of thin films as a novel modification to existing methods of vapor-phase epitaxy, whether physical [e.g., evaporation, at one limit molecular-beam epitaxy (MBE)] or chemical [e.g., chloride epitaxy or metalorganic chemical vapor deposition (MOCVD)]. It is a self-regulatory process which, in its simplest form, produces one complete molecular layer of a compound per operational cycle, with a greater thickness being obtained by repeated cycling. There is no growth rate in ALE as in other crystal growth processes. So far ALE has been applied to rather few materials, but, in principle, it could have a quite general application. It has been used to prepare single-crystal overlayers of CdTe, (Cd,Mn)Te, GaAs and AlAs, a number of polycrystalline films and highly efficient electroluminescent thin-film displays based on ZnS:Mn. It could also offer particular advantages for the preparation of ultrathin films of precisely controlled thickness in the nanometer range and thus may have a special value for growing low-dimensional structures.
Usefulness of procalcitonin in the early detection of infection after thoracic surgery (2005)

Procalcitonin can be used as a reliable diagnostic parameter to detect and to monitor infectious complications in the postoperative period after thoracic surgery, especially in patients felt to be at higher risk (SIRS). It provides more information about the course of the disease than C-reactive protein does, and can be detected before the occurrence of clinical infection.

Feedforward controller design method for position control (2001)

This paper proposes a new controller design method for the multirate sampling case such that the sampling period of the feed-forward control is greater than that of the feedback control. Also this paper proposes a new plant model which includes the same feedback controller. Effectiveness of the proposed method is confirmed by the simulation.
Evaluation of relationship between residual stress of ICs and package warpage caused by flip-chip bonding (2016)

Relationship between the stress of ICs and package warpage caused by flip-chip bonding is evaluated using piezoresistor chip and is measured by Moiré measurement method. The die size is 9×9 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> with 200μm and 550μm in thickness. After non-conductive film laminating, the TEG chip is connected to the organic substrate or the Si interposer by FC bonding. The stress inside the chip was obtained in process of FC bonding by measuring the change in piezo-resistance. The warpage measured by moiré analysis method is in good agreement with the measured residual stress.
Detection of HPV DNA in Cervical Specimens Collected in Cytologic Solution by Ligation-Dependent PCR (2003)

An enhanced radio resource allocation approach for efficient MBMS service provision in UTRAN (2008)

As currently specified by 3GPP, MBMS (multimedia broadcast multicast service) content can be provided in a cell by either point-to-point (P-t-P) or point-to-multipoint (P-t-M) transmission mode, but not both at the same time. In earlier work we highlighted the deficiencies of the current approach and proposed the concept of the ldquodual transmission mode cellrdquo, in which P-t-P (DCH) and P-t-M (FACH) transmissions can coexist and allowed to dynamically adapt through time, to address them. In this paper we further analyze the deficiencies of the current 3GPP approach and enhance our previous work to efficiently address the problem in high mobility scenarios as well. The proposed algorithm takes into consideration both the distribution and the movement of the MBMS userspsila within the cell (using the CPICH Ec/No signal strength as a reference) and dynamically decides which MBMS users should be served using FACH and which should be served using DCH. Simulation results show significant transmission power savings, considerable reduction on the aggregated signaling and processing effort introduced, while QoS requirements are still fulfilled.
