Synthesis and crystal structure of a hexanuclear silver(I) cluster [Ag(Hmna)]6·4H2O (H2mna = 2-mercaptonicotinic acid) and a supramolecular gold(I) complex H[Au(Hmna)2] in the solid state, and their antimicrobial activities (2000)

2-Mercaptonicotinic acid (H2mna = 2-HS(C5H3N)CO2H) gave two types of silver(I) complexes by a reaction with Ag2O suspended in aqueous media; one was a water-insoluble, DMSO-soluble yellow powder [Ag(Hmna)]6·4H2O 1 formed under acidic conditions, and the other was a water-soluble, yellow powder {Na[Ag(mna)]·H2O}n 2 formed under alkaline conditions. These two complexes were interconverted on changing the acidity of the solution. Crystallization by vapor diffusion of the DMSO and aqueous solutions with external acetone gave pale yellow cubic crystals for 1 and pale yellow plate crystals for 2, but structure determination was successful only for 1. The molecular structure of 1 consists of a discrete, hexanuclear silver(I) cluster with the two silver(I) triangles linked by the mercaptonicotinate anions, the geometry around each silver(I) atom being constructed by one aromatic nitrogen atom and two μ-S atoms and the two weak silver(I)–silver(I) interactions. The corresponding gold(I) complex as a water-insoluble, DMSO-soluble yellow powder, H[Au(Hmna)2] 3, was prepared by treatment with aqueous HCl of Na3[Au(mna)2]·2H2O 4 which was obtained by a 1∶4∶8 molar ratio reaction of Na[AuCl4]·2H2O∶H2mna∶NaOH in aqueous solution. Complex 3 crystallized as yellow needle crystals by vapor diffusion of the DMSO solution with external acetone. Its crystal structure with a monomeric 2-co-ordinate AuS2 core shows a supramolecular arrangement by a π–π stacking interaction between two pyridine rings (face-to-face separation 3.42(2)–3.52(1) Å) and, also, by two different hydrogen-bonding interactions; one formed between the carboxyl proton and aromatic nitrogen, and the other an unusual single-mode hydrogen bond between two twisted carboxyl groups. The complexes were also characterized by elemental analysis, TG/DTA, FT-IR, 1H and 13C NMR for 1–4, as well as 109Ag NMR for 2. Noteworthy antimicrobial activities for 1–4, evaluated by minimum inhibitory concentration, were observed.
Adsorption of CO<sub>2</sub> on Fe-doped graphene nano-ribbons: Investigation of transport properties (2017)

<p dir="ltr">Density functional theory combined with the non-equilibrium Green's function formalism is used to study the conductance response of Fe-doped graphene nano-ribbons (GNRs) to CO<sub>2</sub> gas adsorption. A single Fe atom is either adsorbed on GNR's surface (aFe-graphene) or it substitutes the carbon atom (sFe-graphene). Metal atom doping reduces the electronic transmission of pristine graphene due to the localization of electronic states near the impurity site. Moreover, the aFe-graphene is found to be less sensitive to the CO<sub>2</sub> molecule attachment as compared to the sFe-graphene system. These behaviours are not only consolidated but rather confirmed by calculating the IV characteristics from which both surface resistance and its sensitivity to the gas are estimated. Since the change in the conductivity is one of the main outputs of sensors, our findings will be useful in developing efficient graphene-based solid-state gas sensors.</p><h2>Other Information</h2><p dir="ltr">Published in: Journal of Physics: Conference Series<br>License: <a href="http://creativecommons.org/licenses/by/3.0/" rel="noreferrer noopener" target="_blank">http://creativecommons.org/licenses/by/3.0/</a><br>See article on publisher's website: <a href="https://dx.doi.org/10.1088/1742-6596/869/1/012041" target="_blank">https://dx.doi.org/10.1088/1742-6596/869/1/012041</a></p><p dir="ltr">Conference information: Frontiers in Theoretical and Applied Physics/UAE 2017 (FTAPS 2017) 22–25 February 2017, American University of Sharjah (AUS), UAE</p>
A remote bridging technique to increase performability in distributed systems (1994)

The paper presents a network architecture and protocol to extend the facilities available on LAN's to a wider area. The proposal, based on a remote bridging technique, allows selective network reconfiguration and consequently high network availability and performability values. This make the system suitable for applications in environments characterized by hard reliability constraints. The proposed solution is assessed by modeling it through Markov chain theory.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Nuclear Receptors: Overview and Classification (2004)

The nuclear receptor superfamily comprises a large group of transcription factors that play a key regulatory role in development and homeostasis of multicellular organisms. A special feature of nuclear receptors is their ability to bind to condensed chromatin templates, which makes them important initiators of gene transcription. Moreover, the ability of nuclear receptors to sequentially recruit a variety of transcription factors and coregulators to target promoters and to orchestrate the whole process of gene transcription confirms their biological significance and stimulates intensive research and a high level of scientific interest in this field. In this review, we summarise current knowledge regarding the structure and function of nuclear receptors as principal regulators of gene expression. Emphasis is given to the molecular mechanisms of nuclear receptor-mediated transcriptional activation and repression including recent progress made in this area.
Optimal Generalized Inverses for Zero Forcing Precoding (2007)

We consider the problem of linear zero forcing precoding design, and discuss its relation to the theory of generalized inverses in linear algebra. Special attention is given to a specific generalized inverse known as the pseudo-inverse. We begin with the standard design under the assumption of a total power constraint and prove that precoders based on the pseudo-inverse are optimal in this setting. Then, we proceed to examine individual per-antenna power constraints. In this case, the pseudo-inverse is not necessarily the optimal generalized inverse. In fact, finding the optimal inverse is non-trivial and depends on the specific performance measure. We address two common criteria, fairness and throughput, and show that the optimal matrices may be found using standard convex optimization methods. We demonstrate the improved performance offered by our approach using computer simulations.
Parallel Dispatch Queue: a queue-based programming abstraction to parallelize fine-grain communication protocols (1999)

This paper proposes a novel queue-based programming abstraction, Parallel Dispatch Queue (PDQ), that enables efficient parallel execution of fine-grain software communication protocols. Parallel systems often use fine-grain software handlers to integrate a network message into computation. Executing such handlers in parallel requires access synchronization around resources. Much as a monitor construct in a concurrent language protects accesses to a set of data structures, PDQ allows messages to include a synchronization key protecting handler accesses to a group of protocol resources. By simply synchronizing messages in a queue prior to dispatch, PDQ not only eliminates the overhead of acquiring/releasing synchronization primitives but also prevents busy-waiting within handlers. In this paper, we study PDQ's impact on software protocol performance in the context of fine-grain distributed shared memory (DSM) on an SMP cluster. Simulation results running shared-memory applications indicate that: (i) parallel software protocol execution using PDQ significantly improves performance in fine-grain DSM, (ii) tight integration of PDQ and embedded processors into a single custom device can offer performance competitive or better than an all-hardware DSM, and (iii) PDQ best benefits cost-effective systems that use idle SMP processors (rather than custom embedded processors) to execute protocols. On a cluster of 4 16-way SMPs, a PDQ-based parallel protocol running on idle SMP processors improves application performance by a factor of 2.6 over a system running a serial protocol on a single dedicated processor.
Priority-based congestion control in wireless sensor networks (2006)

In wireless sensor networks (WSNs), congestion occurs, for example, when nodes are densely distributed, and/or the application produces high flow rate near the sink due to the convergent nature of upstream traffic. Congestion may cause packet loss, which in turn lowers throughput and wastes energy. Therefore congestion in WSNs needs to be controlled for high energy-efficiency, to prolong system lifetime, improve fairness, and improve quality of service (QoS) in terms of throughput (or link utilization) and packet loss ratio along with the packet delay. This paper proposes a node priority-based congestion control protocol (PCCP) for wireless sensor networks. In PCCP, node priority index is introduced to reflect the importance of each node. PCCP uses packet inter-arrival time along with packet service time to measure a parameter defined as congestion degree and furthermore imposes hop-by-hop control based on the measured congestion degree as well as the node priority index. PCCP controls congestion faster and more energy-efficiency than other known techniques.
Polarized light scattering measurements as a means to characterize particle size and composition of natural assemblages of marine particles (2020)

Polarized light scattering measurements have the potential to provide improved characterization of natural particle assemblages in terms of particle size and composition. However, few studies have investigated this possibility for natural assemblages of marine particles. In this study, seawater samples representing contrasting assemblages of particles from coastal environments have been comprehensively characterized with measurements of angle-resolved polarized light scattering, particle size distribution, and particle composition. We observed robust trends linking samples containing higher proportions of large-sized particles with lower values of the maximum degree of linear polarization and the second element of the scattering matrix at a scattering angle of 100°, <i>p</i><sub>22</sub>(100<sup>∘</sup>). In contrast, lower values of <i>p</i><sub>22</sub>(20<sup>∘</sup>) were found in more non-phytoplankton-or inorganic--dominated samples. We also determined that three measurements involving the combinations of linearly polarized incident and scattered beams at two scattering angles (110° and 18°) have the potential to serve as useful proxies for estimating particle size and composition parameters.
Pulmonary Vascular Wall Stiffness: An Important Contributor to the Increased Right Ventricular Afterload with Pulmonary Hypertension (2011)

Pulmonary hypertension (PH) is associated with structural and mechanical changes in the pulmonary vascular bed that increase right ventricular (RV) afterload. These changes, characterized by narrowing and stiffening, occur in both proximal and distal pulmonary arteries (PAs). An important consequence of arterial narrowing is increased pulmonary vascular resistance (PVR). Arterial stiffening, which can occur in both the proximal and distal pulmonary arteries, is an important index of disease progression and is a significant contributor to increased RV afterload in PH. In particular, arterial narrowing and stiffening increase the RV afterload by increasing steady and oscillatory RV work, respectively. Here we review the current state of knowledge of the causes and consequences of pulmonary arterial stiffening in PH and its impact on RV function. We review direct and indirect techniques for measuring proximal and distal pulmonary arterial stiffness, measures of arterial stiffness including elastic modulus, incremental elastic modulus, stiffness coefficient β and others, the changes in cellular function and the extracellular matrix proteins that contribute to pulmonary arterial stiffening, the consequences of PA stiffening for RV function and the clinical implications of pulmonary vascular stiffening for PH progression. Future investigation of the relationship between PA stiffening and RV dysfunction may facilitate new therapies aimed at improving RV function and thus ultimately reducing mortality in PH.

MMSE Criterion Fast Decision Feedback Equalization Algorithm for Spatial Multiplexing Systems (2006)

Recent studies indicate that spatial multiplexing (SM) scheme has enormous potential for increasing the capacity of MIMO channels in rich scattering environments. In this paper, we present a new MMSE decision feedback equalization algorithm for signal detection in SM systems. The new algorithm separates the order search and the filter generation to avoid recursive ordering operations. Compared to the earlier MMSE-DFE detectors with optimal and suboptimal ordering rules, the new algorithm is less complex and achieves a bit error rate performance that closely approximates that of the standard BLAST algorithm.

Method in ecumenical theology: the lessons so far (1997)

First published in 1996 this book examines the search for unity in the Church. For the previous thirty years pioneering conversations, between pairs of churches or communities, and multilaterally, put forward solutions to old disagreements and began to build a new ecumenical theology. But when it comes to taking actual steps towards unity there is often a drawing-back from the final commitment. G. R. Evans examines the methodology of ecumenical theory and the way it is being taken into the lives of the Churches, from the experience which has been reported so far. This is a necessary stocktaking exercise, as Dr Evans shows that discussions are now so developed that we can list topics which have become recurrent issues. By making judicious use of interdenominational archival material and secondary literature, the author provides a timely resource for all those interested in recent ecumenical progress.
Influence of biomass accumulation on bed expansion characteristics of a down-flow anaerobic fluidized-bed reactor (1998)

This article describes the bed expansion characteristics of a down-flow anaerobic fluidized bed reactor treating a synthetic wastewater. Experiments were carried out in a 0.08 m diameter and 1 m length PVC column. The carrier used was ground perlite (an expanded volcanic rock). Particles characteristics were 0.968 mm in diameter, specific density of 213 kg x m-3 and Umf (minimal fluidization velocity): 2.3 m x h-1. Experimental data of terminal velocities and bed expansion parameters at several biofilm thicknesses were compared to different models predicting the bed expansion of up-flow and down-flow fluidized beds. Measured bed porosities at different liquid superficial velocities for the different biofilm thicknesses were in agreement with the Richardson-Zaki model, when Ut (particle terminal velocity) and n (expansion coefficient) were calculated by linear regression of the experimental data. Terminal velocities of particles at different biofilm thicknesses calculated from experimental bed expansion data, were found to be much smaller than those obtained when Cd (drag coefficient) is determined from the standard drag curve (Lapple and Sheperd, 1940) or with others' correlations (Karamanev and Nikolov, 1992a,b). This difference could be explained by the fact that free-rising particles do not obey Newton's law for free-settling, as proposed by Karamanev and Nikolov (1992a,b) and Karamanev et al. (1996). In the present study, the same free-rising behavior was observed for all particles (densities between 213 and 490 kg x m-3).
Position paper on laboratory testing for patients with haemophilia. A consensus document from SISET, AICE, SIBioC and SIPMeL. (2019)

Haemophilia is an X-linked congenital haemorrhagic disorder characterised by low (or dysfunctional) levels of factor (F) VIII (haemophilia A) or FIX (haemophilia B). Affected females are asymptomatic carriers of the disease and affected males present with the phenotypic disorder characterised by bleeding events (often spontaneous and life-threatening) in the soft tissues and joints. In the most severe forms, bleeding symptoms start early in the neonatal period and may be complicated by arthropathy and the development of FVIII (or FIX) neutralising alloantibodies (inhibitors)1.
Molecular evolution of inversions in Drosophila pseudoobscura: the amylase gene region. (1991)

The amylase region of the third chromosome of Drosophila pseudoobscura has been cloned and localized to cytological band 73A. It is contained within a series of highly polymorphic inversions and serves as a convenient tool for a molecular evolutionary analysis of the inverted gene arrangements. Amylase in D. pseudoobscura is a family of three genes, and some chromosomes have deletions for one or two of them. Two overlapping clones covering 26 kilobases were isolated and used as probes to survey DNA restriction map polymorphism among 28 lines, representing five of the major inversion types found in natural populations, as well as single chromosomes from the closely related species Drosophila persimilis and Drosophila miranda. Restriction-site differences are considerably greater among the various gene arrangements than among chromosomes with the same gene arrangement. Clustering the restriction map haplotypes yielded a dendrogram concordant with the phylogeny generated independently from cytogenetic considerations. The inversion polymorphism is estimated to be about 2 million years old.
Transforming nursing practice: clinical systems and the nursing unit of the future. (2004)

The healthcare industry has historically focused information system expenditures on financial systems. Finally, enabling the practice of clinicians through information systems is beginning to be viewed as a strategic initiative for hospitals and health systems. Vendor applications are now better able to support clinician workflow. Infrastructure is better able to support mobile devices, which bring information to the bedside. Implementation of nursing applications provides a unique opportunity to redesign inefficient and redundant documentation, thereby enabling greater efficiency. Healthcare organizations can jump-start nursing automation by setting a finite and clear tactical plan for initiatives to be rolled out within a year in a single location. The single location enables the organization to experience how well the initiatives integrate to support optimal delivery of care. This article explores nursing information technology initiatives planned to be deployed at a 1,000-bed teaching facility through the use of a Nursing Unit of the Future.

Balancing fairness and efficiency in tiered storage systems with bottleneck-aware allocation (2014)

Multi-tiered storage made up of heterogeneous devices are raising new challenges in allocating throughput fairly among concurrent clients. The fundamental problem is finding an appropriate balance between fairness to the clients and maximizing system utilization.In this paper we cast the problem within the broader framework of fair allocation for multiple resources. We present a new allocation model BAA based on the notion of per-device bottleneck sets. Clients bottlenecked on the same device receive throughputs in proportion to their fair shares, while allocation ratios between clients in different bottleneck sets are chosen to maximize system utilization. We show formally that BAA satisfies fairness properties of Envy Freedom and Sharing Incentive. We evaluated the performance of our method using both simulation and implementation on a Linux platform. The experimental results show that our method can provide both high efficiency and fairness.
