Film Uniformity in Atomic Layer Deposition
Authors: Elers K.‐E. , Blomberg T. , Peussa M. , Aitchison B. , Haukka S. , Marcus S.
Published: January 2006

The sources of non‐uniformity in thin films produced using atomic layer deposition (ALD) have been investigated by reviewing the mechanical hardware of ALD reactors, precursors, and the by‐products of surface reactions. The most common causes of non‐uniformity are overlapping pulses, thermal self‐decomposition of precursors, and non‐uniform gas distribution. Less studied, however, are the consequences of downstream surface reactions of gaseous by‐products. In particular, titanium nitride films have been found to be significantly less uniform than those of transition metal oxides deposited from metal halides. The influence of reaction by‐products on the TiN film growth has been studied by comparing the deposition in the cross‐flow and showerhead style reactors. Finally, the sources of non‐uniformity in plasma enhanced (PE) ALD are illustrated by studying the TiN deposition process.
Distributed policy processing in active‐service based infrastructures
Authors: Yu Wei , Chellappan Sriram , Xuan Dong , Zhao Wei
Published: January 2006

More and more applications in the Internet are requiring an intelligent service infrastructure to provide customized services. In this paper, we present an infrastructure, which can transparently and effectively provide customized active‐services to end users and dynamically adapt to changing customized policies in large distributed heterogeneous environments. The infrastructure consists of two components: the policy agent and middleware box. Particularly, our technologies include: (1) Generic active‐service based infrastructure, where the policy agent can integrate policies requested by applications, and middleware boxes can transparently execute services and (2) Distributed policy processing in the middleware box. We study two policy partitioning schemes to achieve conflict‐free policies for distributed policy processing and guarantee the correctness of the policy execution. We conduct extensive performance evaluations on different schemes proposed. Our experimental results demonstrate that our policy partitioning schemes can effectively generate partition‐capable and conflict‐free policy sets. The evaluation results also show that distributed policy processing can achieve over 70% increase in performance/price ratio with proper assignment of the policy distribution degree compared to a purely centralized approach.

Joint formation in the middle ear: Lessons from the mouse and guinea pig
Authors: Amin Susan , Tucker Abigail S.
Published: January 2006

The malleus, incus and stapes form an ossicle chain in the mammalian middle ear. These ossicles are articulated by joints that link the chain together. In humans and mice, fusion of the ossicles leads to hearing loss. However, in the adult guinea pig the malleus and incus are normally found as a single complex. In this report, we investigate how the malleus and incus form during mouse and guinea pig development. The murine malleus and incus develop from a single condensation that splits to form the two ossicles. Even before a morphological split, we show that the ossicles have distinct genetic identities and joint markers are expressed. In the guinea pig embryo, joint formation is initiated but no cavitation is observed, resulting in a single complex divided by a thin suture. The malleal‐incudo complex in the guinea pig is, therefore, not caused by a defect in joint initiation. Developmental Dynamics 235:1326–1333, 2006. © 2006 Wiley‐Liss, Inc.
Differential inhibition of Wnt‐3a by Sfrp‐1, Sfrp‐2, and Sfrp‐3
Authors: Galli Lisa M. , Barnes Tiffany , Cheng Tina , Acosta Lisa , Anglade Adolph , Willert Karl , Nusse Roel , Burrus Laura W.
Published: January 2006

Secreted frizzled related proteins (Sfrps) are extracellular attenuators of Wnt signaling that play important roles in both embryogenesis and oncogenesis. Although Sfrps are generally thought to bind and sequester Wnts away from active receptor complexes, very little is known about the specificity of Sfrp family members for various Wnts. In the developing chick neural tube, sfrp‐1, 2, and 3 transcripts are expressed in and adjacent to the dorsal neural tube, where Wnt‐1 and Wnt‐3a are expressed. To better define the possible roles of Sfrp‐1, 2, and 3 in the neural tube, we first tested the ability of purified Sfrps to inhibit Wnt‐3a‐induced accumulation of β‐catenin in L cells. We find that both Sfrp‐1 and Sfrp‐2 can inhibit Wnt‐3a activity while Sfrp‐3 cannot. To determine where Sfrp‐1 and Sfrp‐2 impinge on the Wnt signaling pathway, we tested the ability of these Sfrps to inhibit Wnt signaling induced by the addition of LiCl, an inhibitor of GSK‐3. Sfrp‐1 and Sfrp‐2 are unable to inhibit the accumulation of β‐catenin in LiCl‐treated cells, suggesting that the ability of Sfrps to inhibit the accumulation of β‐catenin is GSK‐3 dependent. We have further shown that Sfrp‐2 inhibits the ability of ectopic Wnt‐3a to stimulate proliferation in the developing chick neural tube. These results provide the framework for understanding how Sfrps function to regulate Wnt‐3a activity in developing embryos and in cancer.

Reorganization of cytoplasm in the zebrafish oocyte and egg during early steps of ooplasmic segregation
Authors: Fernández Juan , Valladares Macarena , Fuentes Ricardo , Ubilla Andrea
Published: January 2006

The aim of this work is to determine when and how ooplasmic segregation is initiated in the zebrafish egg. To this end, the organization of the ooplasm and vitelloplasm were examined in oocytes and eggs shortly after activation. Ooplasmic segregation, initiated in the stage V oocyte, led to the formation of ooplasmic domains rich in organelles, and ribonucleoproteins. A linear array of closely arranged peripheral yolk globules separated an outer domain of ectoplasm from an inner domain of interconnected endoplasmic lacunae. The structure of this yolk array and the distribution of microinjected labeled tracers suggests that it may provide a barrier limiting ooplasm transit. Loosely arranged yolk globules at the animal hemisphere allow wide connections between the endoplasm and a preblastodisc domain. Activation caused further segregation of ooplasm, reorganization of endoplasmic lacunae, and blastodisc growth. The presence of an endoplasmic cytoskeleton suggests that these changes may be driven by microtubules and microfilaments. Developmental Dynamics 235:656–671, 2006. © 2006 Wiley‐Liss, Inc.
Why is delta endocytosis required for effective activation of notch?
Authors: Chitnis Ajay
Published: January 2006

A number of recent studies have shown that endocytosis of Notch ligands is required for activation of Notch. There are at least two broad models that account for how Delta endocytosis in one cell might contribute to activation of Notch in the neighboring cell. The first class of models is related to the possibility that Delta endocytosis facilitates S2 cleavage and removal of the Notch extracellular domain, a critical step in Notch activation. A second class of models is related to the possibility that Delta ubiquitylation and endocytosis facilitates interactions between Delta and Notch. In the second set of models, Delta undergoes endocytosis and its subsequent trafficking back to the surface, following modifications or some change in the context in which it is presented, makes Delta a more effective ligand. Though it is still not clear how either or both mechanisms contribute, recent evidence points to the importance of both endocytosis and recycling in Delta signaling.

Published: January 2006

According to the deployment of the Internet, the requirement for multihoming connection, intended to improve the accessibility of networks with higher quality or/and robustness, is becoming serious. However, in the existing or legacy multihoming systems, the proposed routing architecture cannot tolerate further increases in the number of multihoming users. Also, although improvement of accessibility when failures occur could be achieved, it is difficult to effectively use several connections by multihoming under normal operating conditions. In this paper, a multihome architecture based on an overlay network is proposed as a new architecture resolving the above problems. By means of the proposed system, improved scalability with respect to the number of users and flexible (policy) control against incoming traffic are applicable, while also achieving improved accessibility under failure conditions, which is one of the main objectives for multihoming. © 2006 Wiley Periodicals, Inc.

Frequency synchronization technique using replica created by mutual correlation value for classifying the weight in autocorrelation operation
Authors: Horiuchi Takaaki , Saba Takahiko , Sasase Iwao
Published: January 2006

In an orthogonal frequency‐division multiplexing (OFDM) system, a method based on the autocorrelation of two consecutive known symbols is proposed in order to estimate the frequency offset. In this system, the autocorrelation is calculated for all samples in a symbol. When the products of samples are summed and averaged, the product of each sample is weighted by the absolute amplitude of the received sample. Consequently, a sample which exhibits large received absolute amplitude due to the effect of noise is given a large weight. Since the product of samples given a large weight has a large effect on the estimation, it may degrade the estimation accuracy. Based on this idea, this paper proposes a method of reducing the effect of noise in frequency offset estimation, in which a replica constructed on the basis of information concerning the arrival time, the power, and the phase rotation of each path contained in the cross‐correlation is used to determine the weights used in the calculation of the autocorrelation. It is shown by computer simulation that the proposed method can improve the accuracy of frequency offset estimation in the region where the carrier‐to‐noise ratio (CNR) is low. © 2006 Wiley Periodicals, Inc.

Published: January 2006

In this paper, we study the modem architecture for software‐defined radio. We proposed a hierarchical modem architecture and a tree bus structure based on the time constraint and complexity in the signal processing in software‐defined radio. We divided the functions based on the proposed architecture with the Third Generation Partnership Project Direct Sequence‐Frequency Partition Duplex (3GPP DS‐FDD) mode as the evaluation motive and evaluated the processing load and the flexibility. Next, we developed an evaluation board loaded with a CPU and a programmable logic device (PLD) and measured the scale of the proposed architecture and the overhead due to data transfers. On the evaluation board, the proposed architecture was implemented with 551 kGates and 5.1‐Mbit circuit scale, excluding the CPU core and the transmission hardware (Tx‐HW). We verified the overhead of each processor due to data transfers to be about 2.5% of the total processing load. Thus, this architecture achieved a lower frequency for the CPU operating clock and a simpler process flow, and demonstrated the ability to construct an efficient software‐defined radio. © 2006 Wiley Periodicals, Inc.

Published: January 2006

Patients with autoimmune polyendocrine syndrome type I (APS I)suffer from endocrine and non‐endocrine disorders due to mutations in the autoimmune regulator gene (AIRE). Mouse Aire is expressed both in thymic medullary epithelial cells and in peripheral antigen‐presenting cells, suggesting a role in both central and peripheral tolerance. We here report that Aire–/– dendritic cells (DC) activate naive T cells more efficiently than do Aire+/+ DC. Expression array analyses of Aire–/– DC revealed differential regulation of 68 transcripts, among which, the vascular cell adhesion molecule‐1 (VCAM‐1) transcript was up‐regulated in Aire–/– DC. Concurrently, the expression of the VCAM‐1 protein was up‐regulated on both Aire–/– DC and monocytes from APS I patients. Blocking the interaction of VCAM‐1 prevented enhanced Aire–/– DC stimulation of T cell hybridomas. We determined an increased number of DC in spleen and lymph nodes and of monocytes in the blood from Aire–/– mice, and an increased number of blood monocytes in APS I patients. Our findings imply a role for Aire in peripheral DC regulation of T cell activation, and suggest that Aire participates in peripheral tolerance.

The ansa‐indene ligands {1‐Me2Si(3‐C9H6R)2} [R = Me (1), nPr (2), nBu (3), and Bz (4)] were prepared by alkylation of the unsubstituted ansa‐indene. These ligands were converted, by reaction with nBuLi, to the di‐lithium compounds [Li2{1‐Me2Si(3‐C9H5R)2}] [R = Me (5), nPr (6), nBu (7), and Bz (8)]. ansa‐Zirconocenes, [Zr{1‐Me2Si(3‐η5‐C9H5R)2}Cl2] [R = Me (9), nPr (10), nBu (11), and Bz (12)], have been prepared by the reaction of ZrCl4 with 5–8 in diethyl ether/toluene at–78 °C. The molecular structure of meso‐[Zr{1‐Me2Si[3‐η5‐C9H5(CH3)]2}Cl2] (9) and rac‐[Zr{1‐Me2Si[3‐η5‐C9H5(CH2CH2CH3)]2}Cl2] (10) have been determined by single‐crystal X‐ray diffraction studies. Ethylene polymerization catalysis has been studied for complexes 9–12 as a mixture of meso and rac isomers in the presence of methylaluminoxane (MAO) as cocatalyst. Complexes 9–12 exhibit high activities and give rise to polyethylene with low molecular weights without the introduction of molecular hydrogen. In addition, active species from these complexes were found to be very stable in comparison with unsubstituted analogues.(© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)

Reduction of the macrocyclic ligand, 3,10‐meso‐3,5,7,7,10,12,14,14‐octamethyl‐1,4,8,11‐tetraazacyclotetradecane‐4,11‐diene dihydroperchlorate (L), with sodium borohydride yielded three [Lb (1), Lc (2), and Ld (3)] of four possible diastereoisomers. The diastereoisomeric macrocycles and their NiII and CuII complexes have been characterized and confirmed by IR, UV/Vis, and NMR spectroscopy as well as X‐ray crystallography. The chiral carbon centers and methyl groups at the 5 and 12 positions of 1, 2 and 3 have the 5S,12R‐C‐meso, 5S,12S‐C‐racemic, and 5R,12R‐C‐racemic configurations, respectively. In accordance with the X‐ray structure determination, the geometry around the NiII ion in the complexes is approximately square‐planar and the CuII ion has an octahedral geometry. The N–H configuration of [NiLc](ClO4)2(H2O)0.5 (5) is trans‐II, different from the most thermodynamically stable trans‐III configuration that is found in [NiLb](ClO4)2 (4), [CuLb(H2O)2](ClO4)2 (7), and [CuLd(ClO4)2] (8). UV/Vis spectra reveal that NiII complexes exhibit almost 100 % planar species in aqueous solution resulting from steric effects produced by numerous methyl groups, especially axial orientations and distorted structures. In six coordinate CuII complexes, acetonitrile acts as a better axial donor than the water molecule; the weaker axial bonding is a result of steric interactions that lead to stronger in‐plane coordinations.

Advances in the enantioseparation of second‐generation antidepressant drugs by electrodriven methods
Authors: Mandrioli Roberto , Raggi Maria A.
Published: January 2006

Stereochemistry is steadily increasing in importance in the development of new drugs, and the availability of pure enantiomer drugs can make therapy safer and more efficacious. In particular, almost all second‐generation antidepressant drugs possess one or more chiral centres; however, only some of them are administered as single enantiomers. A fundamental part of the quality control of pharmaceutical formulations is the determination of enantiomeric excess and enantiomeric purity; this is also important for the therapeutic drug monitoring of depressed patients. For this purpose, efficient and reliable analytical methods are needed and electrodriven techniques (most of all CE, CEC and MEKC) are very efficient and inexpensive candidates for the role. In this review, the enantioselective electrodriven methods available for the analysis of second‐generation antidepressant are presented and discussed. In particular, the following pharmacological classes of antidepressants will be considered: selective serotonin reuptake inhibitors (fluoxetine, citalopram, paroxetine, sertraline); norepinephrine reuptake inhibitors (reboxetine); serotonin and norepinephrine reuptake inhibitors (venlafaxine, milnacipran, duloxetine); and noradrenergic and specific serotonergic antidepressants (mirtazapine).

Emerging systems biology aims at integrating the enormous amount of existing omics data in order to better understand their functional relationships at a whole systems level. These huge datasets can be obtained through advances in high‐throughput, sensitive, precise, and accurate analytical instrumentation and technological innovation. Separation sciences play an important role in revealing biological processes at various omic levels. From the perspective of systems biology, CE is a strong candidate for high‐throughput, sensitive data generation which is capable of tackling the challenges in acquiring qualitative and quantitative knowledge through a system‐level study. This review focuses on the applicability of CE to systems‐based analytical data at the genomic, transcriptomic, proteomic, and metabolomic levels.
