Storage and Executive Processes in the Frontal Lobes (1999)

The human frontal cortex helps mediate working memory, a system that is used for temporary storage and manipulation of information and that is involved in many higher cognitive functions. Working memory includes two components: short-term storage (on the order of seconds) and executive processes that operate on the contents of storage. Recently, these two components have been investigated in functional neuroimaging studies. Studies of storage indicate that different frontal regions are activated for different kinds of information: storage for verbal materials activates Broca's area and left-hemisphere supplementary and premotor areas; storage of spatial information activates the right-hemisphere premotor cortex; and storage of object information activates other areas of the prefrontal cortex. Two of the fundamental executive processes are selective attention and task management. Both processes activate the anterior cingulate and dorsolateral prefrontal cortex.
Hematopoietic Stem Cells from <i>Fancc</i> <sup>−/−</sup> Mice Have Lower Growth and Differentiation Potential in Response to Growth Factors (2002)

Fanconi anemia (FA) is a complex recessive genetic disease characterized by progressive bone marrow (BM) failure. We have previously shown that stem cells from the FA group C mouse model have lower long-term primary and secondary reconstitution ability, and that bone marrow of Fancc(-/-) mice contained fewer lineage-negative (Lin(-))Thy1.2(low)Sca-1(+)c-kit(+) CD34(+) cells but normal levels of Lin(-)Thy1.2(low)Sca-1(+)c-kit(+)CD34(-) primitive cells. These data suggest that CD34(+) primitive cells have either a lower growth or differentiation potential, or that these cells have greater apoptosis levels. To investigate the role Fancc might have on the growth and differentiation potentials of primitive hematopoietic stem cells, we used a single-cell culture system and monitored cell viability, doubling potential, and apoptosis levels of Fancc(-/-) primitive Lin(-)Thy1.2(-)Sca-1(+) (LTS)-CD34(+) and LTS-CD34(-) stem cells. Results showed that Fancc(-/-) LTS-CD34(-) and LTS-CD34(+) cells had altered growth and apoptosis responses to combinations of stimulatory cytokines, most dramatically in response to a combination of factors that included interleukin-3 (IL-3) and IL-6. In addition, Fancc(-/-) LTS-CD34(-) and LTS-CD34(+) cells showed a lower differentiation potential than Fancc(+/+) cells. These results support a role for Fancc in the growth and differentiation of primitive hematopoietic cells and suggest that an altered response to stimulatory cytokines may contribute to BM aplasia in FA patients.
Autologous Graft-versus-Tumor Effect: Reality or Fiction? (2016)

In contrast to allogeneic hematopoietic stem cell transplantation, the current dogma is not an evidence of graft-versus-tumor effect in autologous hematopoietic stem cell transplantation; thus, it is assumed that autologous hematopoietic stem cell transplantation only relies on the high-dose chemotherapy to improve clinical outcomes. However, recent studies argue in favor of the existence of an autologous graft-versus-tumor without the detrimental complications of graft-versus-host disease due to the nonspecific immune response from the infused donor alloreactive immune effector cells in allogeneic hematopoietic stem cell transplantation. Herein, this paper reviews the clinical evidence of an autologous graft-versus-tumor effect based on the autograft collected and infused host immune effector cells and host immunity recovery after autologous hematopoietic stem cell transplantation affecting clinical outcomes in cancer patients.
Increased levels of sCD23 in rheumatoid arthritis are related to disease status. (1994)

The low affinity receptor for IgE (Fc epsilon RII, CD23) is involved in many aspects of T and B cell regulation. In the current study, serum levels of sCD23 were measured in monozygotic (MZ) twins discordant for rheumatoid arthritis (RA) to examine whether an increased level of sCD23 in RA is, at least in part, genetically determined. Paired analysis showed significantly elevated sCD23 levels in affected twins when compared with their unaffected co-twins (p < 0.01). There was no significant difference in sCD23 in the unaffected twins compared with normal controls. Higher levels of sCD23 were found in males compared to females in both affected and unaffected twins. Soluble CD23 showed a significant increase with age in RA affected twins (p = 0.013), but no association with disease duration (p = 0.87). There was no significant variation in sCD23 level with HLA-DR phenotype. We conclude that elevations in serum sCD23 in patients with RA are primarily disease related.
The Recuperative Auto Thermal Reforming and Recuperative Reforming Gas Turbine Power Cycles With CO2 Removal—Part II: The Recuperative Reforming Cycle (2004)

The relatively innovative gas turbine based power cycles R-ATR and R-REF (recuperative–auto thermal reforming GT cycle and recuperative–reforming GT cycle) here proposed, are mainly aimed to allow the upstream CO2 removal by the natural gas fuel reforming. The second part of the paper is dedicated to the R-REF cycle: the power unit is a gas turbine (GT), fuelled with reformed and CO2 cleaned gas, obtained by the addition of several sections to the simple GT cycle, mainly: • reformer section (REF), where the reforming reactions of methane fuel with steam are accomplished: the necessary heat is supplied partially by the exhausts cooling and, partially, with a post-combustion, • water gas shift reactor (WGSR), where the reformed fuel is, shifted into CO2 and H2 with the addition of water, and • CO2 removal unit for the CO2 capture from the reformed and shifted fuel. No water condensing section is adopted for the R-REF configuration. Between the main components, several heat recovery units are applied, together with GT cycle recuperator, compressor intercooler, and steam injection into the combustion chamber. The CO2 removal potential is close to 90% with chemical absorption by an accurate choice of amine solution blend: the heat demand for amine regeneration is completely self-sustained by the power cycle. The possibility of applying steam blade cooling (the steam is externally added) has been investigated: in these conditions, the R-REF has shown efficiency levels close to 43–44%. High values of specific work have been observed as well (around 450–500 kJ/kg). The efficiency is slightly lower than that found for the R-ATR solution, and 2–3% lower than CRGTs with CO2 removal and steam bottoming cycle, not internally recuperated. If compared with these, the R-REF offers higher simplicity due to absence of the steam cycle, and can be regarded as an improvement to the simple GT. In this way, at least 5–6 points efficiency can be gained, together with high levels of CO2 removal. The effects of the reformed fuel gas composition, temperature, and pressure on the amine absorption system for the CO2 removal have been investigated, showing the beneficial effects of increasing pressure (i.e., pressure ratio) on the specific heat demand.
Highly oriented layers of the three-dimensional semiconductor CdTe on the two-dimensional layered semiconductors MoTe2 and WSe2 (1996)

The II–VI semiconductor CdTe was sequentially deposited onto the (0001) van der Waals surfaces of the layered compound semiconductors MoTe2 and WSe2 by molecular beam epitaxy. Growth could only be achieved after deposition of a nucleation layer of CdTe at room temperature. After nucleation subsequent deposition steps followed at increased substrate temperatures (T=170–370 °C) in order to increase the crystalline quality of the films. The deposited films were investigated after each growth step by low energy electron diffraction and photoelectron spectroscopy. The diffraction pattern indicates a facetting of the (111) oriented film surfaces. From photoemission data we exclude interface reactions between substrate and film material. Transmission electron microscopy was used to examine the film morphology after the UHV experiments. The mean diameter of the film crystallites is 200–400 Å.
Lossless compression technique for the fronthaul of LTE/LTE-advanced cloud-RAN architectures (2013)

Some of the most advanced functionalities in LTE and LTE-Advanced wireless networks rely upon some kind of collaborative processing between cells, as happens in coordinated scheduling, Cooperative Multi-Point (CoMP), or enhanced Inter-Cell Interference Coordination (eICIC), among other techniques. In some of these functionalities the required amount of information exchange between cells is so high that centralized processing scenarios represent a more viable alternative, whereby central nodes perform baseband processing tasks and remote radio heads are connected to them via high-capacity fiber links (usually known as fronthaul links). The high fiber cost incurred by these so-called Cloud-RAN architectures is the main drawback for practical deployments, and compression techniques are therefore needed at the fronthaul network. The present paper explores a lossless compression technique for LTE and LTE-Advanced wireless networks where actual compression ratios depend upon the resources occupancy, thereby allowing for statistical multiplexing in the aggregation network which translates into significant cost reductions. Compression ratios as high as 30:1 can be achieved in lightly loaded LTE 2×2 MIMO cells while values around 6:1 are typically obtained for 50% cell loads.

Cocrystal Engineering of a Prototype Energetic Material: Supramolecular Chemistry of 2,4,6-Trinitrotoluene (2010)

A unique approach to alter the properties of existing energetic materials through cocrystallization is presented. The structure and properties of 17 new cocrystals of the benchmark energetic material 2,4,6-trinitrotoluene (TNT) are elucidated. The donor−acceptor π−π interaction represents a reliable supramolecular synthon for the formation of cocrystals with this aromatic energetic material. When present, amine−nitro interactions direct secondary packing in these crystals. A detailed study of the cocrystals formed reveals an alteration of key properties including density, packing coefficient, melting point, and decomposition temperature. Cocrystallization provides the opportunity to tune properties of existing energetics to create superior materials and provides a complementary alternative to traditional methods that focus primarily on the synthesis of new compounds and/or the discovery of polymorphs with the most attractive properties.
HLA-DR <i>beta</i> genes vary in number between different DR specificities, whereas the number of DQ <i>beta</i> genes is constant. (1985)

Probes isolated from DR and DQ beta cDNA and genomic clones were used in hybridizations to restriction enzyme-digested DNA from human homozygous typing cells (HTC) as well as other DR homozygous cells in order to estimate the number of beta genes in the DR/DQ class II region. Varying numbers of DR beta genes were found in HTC of different DR specificities, from possibly one in DR 8 cells to three in cells of DR 2 to 7. The DR beta genes of different specificities seem to be related to one another in a distinct fashion. In contrast, all HTC contain two DQ beta genes per chromosome. The restriction site polymorphism of DQ beta genes is considerably more extensive than that of DQ serology, although one of the genes seems to be nonpolymorphic. In addition to the two DP beta genes identified previously, a minimum of three to five DQ and DR beta genes exist in the human haploid genome.

Synthesis of (−)-Calicoferol B (2002)

The first total synthesis of (-)-calicoferol B (III) is described. The cyclozirconation product I, prepared in enantiomerically pure form, was converted into the CD ring chiron II. This was coupled with the aromatic A-ring, and then the side chain was constructed with control of relative and absolute configuration to complete the total synthesis of III. The first total synthesis of (-)-calicoferol B (1) is described. The cyclozirconation product 8, prepared in enantiomerically pure form, was converted into the CD ring chiron 6. This was coupled with the aromatic A-ring, and then the side chain was constructed with control of relative and absolute configuration to complete the total synthesis of 1.
Nonionic Block Copolypeptide Micelles Containing a Hydrophobic <i>rac</i>-Leucine Core (2010)

Block copolymer micelles have been used extensively as carriers for therapeutic drugs and diagnostic molecules. Here, we report the synthesis of nonionic, block copolypeptides, K(P) (x)(rac-L)(y), which have a "reversed" rod-coil structure composed of a hydrophilic, rod-like, α-helical segment attached to a disordered, racemic hydrophobic segment. The self assembly of these block copolypeptides in water was studied, and their compositions were optimized to identify a sample, K(P) (100)(rac-L)(10), which is able to form well defined micelles that are very stable against dilution, high temperatures, and various media. Micelle structure was determined using a combination of electron microscopy and dynamic light scattering measurements. The potential of these micelles as drug delivery carriers was evaluated by encapsulation of the anticancer drug camptothecin. The drug containing micelles were found to be stable.
Amyloid β concentrations and stable isotope labeling kinetics of human plasma specific to central nervous system amyloidosis (2017)

Blood plasma Aβ42 shows similar amyloid-associated alterations as we have previously reported in cerebrospinal fluid, suggesting a blood-brain transportation mechanism of Aβ. The stability and sensitivity of plasma Aβ measurements suggest this may be a useful screening test for central nervous system amyloidosis.
Cloud Service Selection Based on the Aggregation of User Feedback and Quantitative Performance Assessment (2013)

Cloud computing has been attracting huge attention in recent years. More and more individuals and organizations have been moving their work into cloud environments because of its flexibility and low-cost. Due to the emergence of a variety of cloud service providers, selecting the most suitable cloud service becomes increasingly important for potential cloud users. In prior studies, the selection and comparison of cloud services usually focus on objective performance analysis based on cloud monitoring and benchmark testing without considering the viewpoints of cloud users who are indeed consuming cloud services. This causes a problem that some vital aspects which concern cloud consumers (e.g., privacy and cloud providers' reputation) are not taken into account in cloud service selection. In this paper, we propose a novel model of cloud service selection by aggregating the information from both the feedback from cloud users and objective performance analysis from a trusted third party. Based on this model, we first propose a framework which supports our cloud service selection approach. Then after classifying subjective assessment and objective assessment, we present a novel cloud service selection approach to aggregate all subjective assessments and objective assessments through a fuzzy simple additive weighting system. In addition, to reduce the bias caused by unreasonable feedback from unprofessional or malicious cloud users, a method is proposed for filtering the feedback from such users. After processing, the aggregated result can quantitatively reflect the overall quality of a cloud service. Finally, a case study is presented to illustrate the advantages of our approach.

Facile Solution Synthesis of α-FeF<sub>3</sub>·3H<sub>2</sub>O Nanowires and Their Conversion to α-Fe<sub>2</sub>O<sub>3</sub> Nanowires for Photoelectrochemical Application (2012)

We report for the first time the facile solution growth of α-FeF(3)·3H(2)O nanowires (NWs) in large quantity at a low supersaturation level and their scalable conversion to porous semiconducting α-Fe(2)O(3) (hematite) NWs of high aspect ratio via a simple thermal treatment in air. The structural characterization by transmission electron microscopy shows that thin α-FeF(3)·3H(2)O NWs (typically <100 nm in diameter) are converted to single-crystal α-Fe(2)O(3) NWs with internal pores, while thick ones (typically >100 nm in diameter) become polycrystalline porous α-Fe(2)O(3) NWs. We further demonstrated the photoelectrochemical (PEC) application of the nanostructured photoelectrodes prepared from these converted hematite NWs. The optimized photoelectrode with a ~400 nm thick hematite NW film yielded a photocurrent density of 0.54 mA/cm(2) at 1.23 V vs reversible hydrogen electrode potential after modification with cobalt catalyst under standard conditions (AM 1.5 G, 100 mW/cm(2), pH = 13.6, 1 M NaOH). The low cost, large quantity, and high aspect ratio of the converted hematite NWs, together with the resulting simpler photoelectrode preparation, can be of great benefit for hematite-based PEC water splitting. Furthermore, the ease and scalability of the conversion from hydrated fluoride NWs to oxide NWs suggest a potentially versatile and low-cost strategy to make NWs of other useful iron-based compounds that may enable their large-scale renewable energy applications.
Analysis of Fingerprint Image Enhancement using Gabor Filtering with Different Orientation Field Values (2017)

<p>Fingerprint image enhancement is the key process in IAFIS systems. In order to reduce false identification ratio and to supply good fingerprint images to IAFIS systems for exact identification, fingerprint images are generally enhanced. A filtering process tries to filter out the noise from the input image, and emphasize on low, high and directional spatial frequency components of an image. This paper presents an experimental summary of enhancing fingerprint images using Gabor filters. Frequency, width and window domain filter ranges are fixed. The orientation angle alone is modified by 0 radians, , and radians. The experimental results show that Gabor filter enhances the fingerprint image in a better way than other filtering methods and extracts features. </p>
Double-side planar-doped AlGaAs/InGaAs/AlGaAs MODFET with current density of 1 A/mm (1991)

AlGaAs/InGaAs/AlGaAs double-side planar-doped (DSPD) pseudomorphic MODFETs of 0.3- mu m gate length with both excellent DC and RF performances are reported. A maximum unilateral gain cutoff frequency of 170 GHz and a maximum current gain cutoff frequency of 60 GHz are achieved. The devices exhibit a maximum transconductance of 500 mS/mm and an extremely high current density of 1 A/mm. These are the highest frequencies reported so far for MODFET devices capable of driving 1-A/mm current density. This current density is the highest ever reported with this type of layer structure.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
A New Approach for Multi-device User Interface Design (2007)

A large number of heterogeneous and computing devices, such as PCs, PDAs, and cell phones, nowadays are used to access the same information. Currently, designers designing such multi-device user interfaces have to design a UI separately for each device, which is a time consuming and error prone activity. This paper discusses our approach to the multi-device interface development. We describe how abstract UI descriptions with FMP model. We also discuss how get adaptive presentational models for various devices with UI templates and UI design patterns help. Lastly, with code generate tool help, concrete user interfaces are generated.
A smart card CMOS circuit with magnetic power and communication interface (2002)

On-chip magnetic interface provides power supply and communication for a chip dedicated to contactless smart card applications. Smart cards equipped with a chip, instead of a magnetic ribbon, are becoming widely used due to the reliability at system level. Contactless solutions present advantages: reduced card cost (no bonding), and improved system reliability due to the absence of electrical contacts between card and terminal. Implementing an on-chip coil to eliminate pads results in increased chip area. Economic estimates show an area less than 4mm2 seems to represent a good challenge for this approach. To achieve good power transfer between terminal antenna and on-chip coil, it is necessary to reduce the distance between the two antennas (typically a few mm), not difficult in a smart card environment. For economic reasons, the work uses a standard industrial CMOS process, with no additional process steps.
Adaptive coding for packetized data in wireless networks (2002)

In the last decade the growth of wireless communication has been rapid. One critical issue in wireless systems is the efficient encoding of data to ensure correctness in the presence of noise and multipath fading. We propose some encoding schemes which span the FEC/ARQ spectrum and analyze them with respect to throughput and delay. We conclude with an adaptive algorithm for choosing the optimal encoding scheme based on observed error rates.
