Allocation of control and data channels for Large-Scale Wireless Sensor Networks (2008)

Both IEEE 802.15.4 and 802.15.4a standards allow for dynamic channel allocation and use of multiple channels available at their physical layers but its MAC protocols are designed only for single channel. Also, sensor's transceivers such as CC2420 provide multiple channels and as shown in [1], [2] and [3] channel switch latency of CC2420 transceiver is just about 200$μ$s. In order to enhance both energy efficiency and to shorten end to end delay, we propose, in this report, a spectrum-efficient frequency allocation schemes that are able to statically assign control channels and dynamically reuse data channels for Personal Area Networks (PANs) inside a Large-Scale WSN based on UWB technology.
Public health leadership and the COVID-19 pandemic in Europe (2021)

The COVID-19 pandemic has emphasised that calls for clearer mandates and leadership from health authorities has gone unheard for decades. Preventable occurrences in response to the pandemic depict that countries in the WHO European Region suffer from various issues that undermine public health leadership – a necessary capacity to navigate extraordinary times, such as these. What remains clear is that there is a dire need for public health to be reinforced and enabled to ensure effective public health responses. Furthermore, internal siloes within the field must be broken down and collaboration within and across sectors nurtured, to help build up resilience to handle future emergencies.
Target for Glycemic Control in Type 2 Diabetic Patients on Hemodialysis: Effects of Anemia and Erythropoietin Injection on Hemoglobin A<sub>1c</sub> (2009)

In hemodialysis (HD) patients the glycated hemoglobin (Hb(A1c)) level may underestimate glycemic control. The aim of this study is to estimate accurate glycemic control in type 2 diabetic patients on HD. Type 2 diabetes patients (N = 87) who had been receiving maintenance HD for at least one year were enrolled. Hb(A1c) and the percentage of glycated albumin relative to total the serum albumin (%GA) were measured in blood samples and the factors that affected the %GA/Hb(A1c) ratio were examined. There were significant and positive correlations between the plasma glucose and either the Hb(A1c) levels (r = 0.539, P < 0.01) or the %GA level (r = 0.520, P < 0.01). No relationship between the serum albumin levels and %GA levels was observed. A weekly dose of erythropoietin (EPO) was positively correlated with the ratio of %GA/Hb(A1c) and hematocrit (Ht) correlated negatively. There was no significant correlation between the %GA/Hb(A1c) level and the EPO dose in patients with Ht > or = 30%, although a significant correlation was found between those parameters in the Ht < 30% group. The mean of the %GA/Hb(A1c) ratios in patients with Ht > or = 30%, with Ht < 30% and treated with EPO < 100 IU/kg/week, and with Ht < 30% and treated with EPO > or = 100 IU/kg/week were 3.41, 3.56 and 4.13, respectively. In HD patients, accurate glycemic control may be estimated as: Hb(A1c) x 1.14 if Ht > or = 30%; Hb(A1c) x 1.19 if Ht < 30% and treated with low dosages of EPO; and Hb(A1c) x 1.38 if Ht < 30% and treated with high dosages of EPO.
Virus infection, antiviral immunity, and autoimmunity (2013)

As a group of disorders, autoimmunity ranks as the third most prevalent cause of morbidity and mortality in the Western World. However, the etiology of most autoimmune diseases remains unknown. Although genetic linkage studies support a critical underlying role for genetics, the geographic distribution of these disorders as well as the low concordance rates in monozygotic twins suggest that a combination of other factors including environmental ones are involved. Virus infection is a primary factor that has been implicated in the initiation of autoimmune disease. Infection triggers a robust and usually well-coordinated immune response that is critical for viral clearance. However, in some instances, immune regulatory mechanisms may falter, culminating in the breakdown of self-tolerance, resulting in immune-mediated attack directed against both viral and self-antigens. Traditionally, cross-reactive T-cell recognition, known as molecular mimicry, as well as bystander T-cell activation, culminating in epitope spreading, have been the predominant mechanisms elucidated through which infection may culminate in an T-cell-mediated autoimmune response. However, other hypotheses including virus-induced decoy of the immune system also warrant discussion in regard to their potential for triggering autoimmunity. In this review, we discuss the mechanisms by which virus infection and antiviral immunity contribute to the development of autoimmunity.
Mapping of chromatic-dispersion distribution along optical fibers with 20-m spatial resolution (2005)

The accurate mapping of chromatic-dispersion distribution along single-mode optical fibers with the best spatial resolution ever reported is experimentally demonstrated. The method consists of a new way of probing four-wave-mixing (FWM) efficiency along the fiber using Brillouin-optical-time-domain analysis (BOTDA). The new setup eliminates many noise problems found in previous configurations, allowing a tenfold improvement in the spatial resolution of this kind of measurements. Resolutions of 20 m in a 1.1-km standard fiber and 150 m in a 6.7-km dispersion-shifted fiber (DSF), respectively, were achieved.
A Systematic Classification and Analysis of NFRs (2013)

The main agenda of Requirements Engineering (RE) is the development of tools, techniques and languages for the elicitation, specification, negotiation, and validation of software requirements. However, this development has traditionally been focused on functional requirements (FRs), rather than non-functional requirements (NFRs). Consequently, NFR approaches developed over the years have been fragmental and there is a lack of clear understanding of the positions of these approaches\nin the RE process. This paper provides a systematic classification and analysis of 89 NFR approaches.
Exceptional Perrhenate/Pertechnetate Uptake and Subsequent Immobilization by a Low-Dimensional Cationic Coordination Polymer: Overcoming the Hofmeister Bias Selectivity (2017)

We report one of the most efficient scavenger materials, a cationic crystalline coordination polymer SBN for trapping ReO4–, a surrogate for 99TcO4–, as an anionic radioactive contaminant of great concern. The uptake capacity for ReO4– reaches 786 mg/g, a value noticeably higher than the state of art anion-exchange resins and other inorganic or hybrid anion sorbents. Once being captured, ReO4– is greatly immobilized, as almost no ReO4– can be eluted using large excess of nitrate, carbonate, and phosphate anions. The processes are featured by a complete and irreversible single-crystal to single-crystal structural transformation from SBN to the ReO4–-incorporated phase (SBR). The coordination environments of NO3– and ReO4– probed by single-crystal structures clearly unravel the underlying mechanism, where each ReO4– in SBR binds to multiple Ag+ sites forming strong Ag–O–Re bonds, and to 4,4′-bipyridine through a dense hydrogen bond network. These structural insights lead to a significant difference in solubility product constants between SBN and SBR, which is further confirmed by first principle calculations showing a large binding energy difference of 35.61 kcal/mol. To the best of our knowledge, SBR is the least soluble perrhenate/pertechnetate salt reported, which may be considered as a potential waste form for direct immobilization of TcO4–.
Vacuum Evaporation of Pure Metals (2012)

Abstract Theories on the evaporation of pure substances are reviewed and applied to study vacuum evaporation of pure metals. It is shown that there is good agreement between different theories for weak evaporation, whereas there are differences under intensive evaporation conditions. For weak evaporation, the evaporation coefficient in Hertz-Knudsen equation is 1.66. Vapor velocity as a function of the pressure is calculated applying several theories. If a condensing surface is less than one collision length from the evaporating surface, the Hertz-Knudsen equation applies. For a case where the condensing surface is not close to the evaporating surface, a pressure criterion for intensive evaporation is introduced, called the effective vacuum pressure , p eff . It is a fraction of the vapor pressure of the pure metal. The vacuum evaporation rate should not be affected by pressure changes below p eff , so that in lower pressures below p eff , the evaporation flux is constant and equal to a fraction of the maximum evaporation flux given by Hertz-Knudsen equation as 0.844 $$ \dot{n}_{\hbox{Max} } $$ . Experimental data on the evaporation of liquid and solid metals are included.
Effect of windowing and zero‐filled reconstruction of MRI data on spatial resolution and acquisition strategy (2001)

Standard, MR spin-warp sampling strategies acquire data on a rectangular k-space grid. That method samples data from the "corners" of k-space, i.e., data that lie in a region of k-space outside of an ellipse just inscribed in the rectangular boundary. Illustrative calculations demonstrate that the data in the corners of k-space contribute to the useful resolution only if an interpolation method such as a zero-filled reconstruction is used. The consequences of this finding on data acquisition and data windowing strategies are discussed. A further implication of this result is that the spatial resolution of images reconstructed with zero-filling (but without radial windowing) is expected to display angular dependence, even when the phase- and frequency-encoded resolutions are identical. This hypothesis is experimentally verified with a slit geometry phantom. It is also observed that images reconstructed without zero-filling do not display the angular dependence of spatial resolution predicted solely by the maximal k-space extent of the raw data. The implications of these results for 3D contrast-enhanced angiographic acquisitions with elliptical centric view ordering are explored with simulations.
Collaborative Active Learning of a Kernel Machine Ensemble for Recognition (2013)

Active learning is an effective way of engaging users to interactively train models for visual recognition. The vast majority of previous works, if not all of them, focused on active learning with a single human oracle. The problem of active learning with multiple oracles in a collaborative setting has not been well explored. Moreover, most of the previous works assume that the labels provided by the human oracles are noise free, which may often be violated in reality. We present a collaborative computational model for active learning with multiple human oracles. It leads to not only an ensemble kernel machine that is robust to label noises, but also a principled label quality measure to online detect irresponsible labelers. Instead of running independent active learning processes for each individual human oracle, our model captures the inherent correlations among the labelers through shared data among them. Our simulation experiments and experiments with real crowd-sourced noisy labels demonstrated the efficacy of our model.
Development changes in the human cardiac isomyosin distribution: an immunohistochemical study using monoclonal antibodies. (1987)

With monoclonal antibodies (Mab) specific for myosin heavy chain (MHC) isozymes, we have investigated the isomyosin content of atrial, ventricular and conductive fibers of 19 human fetuses (ranging from 14-36 weeks of gestation) and 3 newborns (2 days-2 weeks). In addition, the conduction system of 2 human adult hearts was studied. The fetal atrium is composed mostly of alpha-MHC during the first 23 weeks of gestation. beta-MHC is already expressed as traces at 14 weeks of gestation, and its expression increases progressively until birth, resulting in a great augmentation in beta-MHC. During this course, beta-MHC always predominates in certain areas (the crista terminalis and the interatrial septum) but not in other areas (the auricles). Preceding birth, the fetal ventricle is composed mostly of beta-MHC. From 14 weeks of gestation to birth, alpha-MHC is expressed in very rare fibers. Then, after birth, a large number of fibers simultaneously synthesize alpha-MHC. The AV node and His bundle system were labelled with anti-alpha and anti-beta Mab in fetal, newborn, and adult hearts with a double gradient of distribution: spatial (a higher proportion of alpha-containing fibers in the AV node than in the distal portion of the bundle of branches) and temporal (a higher proportion of alpha-containing fibers at a given point in fetal development than in the adult heart). One of the twenty-five hearts studied had an isomyosin distribution pattern not accorded to its age. Interestingly, it was clinically diagnosed as having idiopathic hypertrophic cardiomyopathy.
Immunohistochemical evaluation of the expression of prostate tumor‐association markers in the nude mouse human prostate carcinoma heterotransplant lines PC‐82, PC‐EW, and PC‐EG (1990)

The biotin-avidin immunoperoxidase assay was used to evaluate the expression of several prostate carcinoma-associated markers in formalin-fixed paraffin-embedded tissue sections of three human prostate nude mouse heterotransplant lines PC-82, PC-EW, and PC-EG. In addition to monoclonal antibodies to PSA and PAP, monoclonal antibodies to five other potentially useful markers for prostate carcinomas (TURP-27, Leu-7, 7E11-C5, PSP-19, and PD41) were tested. Tissues from two or more transplant passages were evaluated. The human prostate target antigens were found to be expressed by one or more of the three heterotransplant lines. The PC-82 and PC-EW lines were the most efficient in terms of expression of multiple prostate carcinoma-associated markers and percentage of tumor cells positive for a given prostate antigen. The staining pattern of each marker, in terms of staining intensity, number of tumor cells stained, and staining location, i.e., membrane, cytoplasmic, or ductal secretions, was similar to what has been observed in tissue sections from human prostate carcinomas. The lack of an appropriate model for evaluating the preclinical potential of these Mabs (especially TURP-27, PSP-19, and PD41) makes the findings of this study of considerable importance, and suggests that these human prostate xenografts may be useful models for exploring the diagnostic and therapeutic potential of these anti-prostate carcinoma monoclonal antibodies.
Venoms, poisons and toxins: evolution and impact of amazing molecules. (2020)

Venoms 2019, the 6th international meeting on Toxinology at Oxford, co-chaired by Professor David Warrell (University of Oxford, UK) and Dr Edward Rowan (Strathclyde University, UK), successfully accomplished its aims. With over 70 oral and poster presentations this meeting focused largely on venoms. However, topics covering bacterial toxins were also included. One of the aims of the meeting was to allow ample time for discussion and to encourage the formation of new networks as well as re-invigorating established collaborations. More than 100 participants, both established and emerging researchers, came from 22 countries, representing academic institutions, government research organisations, funding bodies, industry, and regional and international charitable organisations. Below is a brief summary of the presentations given at this meeting.

Wavelength division multiplexing-dense wavelength division multiplexed passive optical network (WDM-DWDM-PON) for long reach terrain connectivity (2016)

The wavelength division multiplexed and dense wavelength division multiplexed passive optical network (WDM-DWDM-PON) is designed and simulated to serve as long reach passive optical network (LR-PON). WDM-DWDM-PON network is simulated and analyzed upto the fiber reach of 100Km with and without dispersion compensation techniques. 16 Downstream WDM channels are modulated at the peak rate of 10Gb/s and 32 upstream DWDM channels are modulated at the rate of 2.5Gb/s. Optimum launch power and maximum reach of the fiber are calculated for each downstream and upstream case.
A Hierarchical Gene-Set Genetic Algorithm (2008)

In this paper, gene sets, instead of individual genes, are used in the genetic process to speed up convergence. A gene-set mutation operator is proposed, which can make several neighboring genes to simultaneously mutate. A gene-set crossover operator is also designed to choose the crossover points at the boundary of gene sets. The proposed gene-set mutation and crossover operators will cause a larger diversity than the conventional ones. A hierarchical gene-set genetic algorithm is then proposed, which uses adjustable gene-set lengths to find final solutions. Different phases of populations use different gene-set lengths to perform the genetic operations. The gene-set length is shortened in half in each phase until the length is 1. Experiments on three problems are also made to show the effectiveness of the proposed gene-set genetic algorithm.
Signal processing of white-light interferometric low-finesse fiber-optic Fabry–Perot sensors (2013)

Signal processing for low-finesse fiber-optic Fabry-Perot sensors based on white-light interferometry is investigated. The problem is demonstrated as analogous to the parameter estimation of a noisy, real, discrete harmonic of finite length. The Cramer-Rao bounds for the estimators are given, and three algorithms are evaluated and proven to approach the bounds. A long-standing problem with these types of sensors is the unpredictable jumps in the phase estimation. Emphasis is made on the property and mechanism of the "total phase" estimator in reducing the estimation error, and a varying phase term in the total phase is identified to be responsible for the unwanted demodulation jumps. The theories are verified by simulation and experiment. A solution to reducing the probability of jump is demonstrated.
A facile synthesis of a novel triptycene-containing A–B monomer: precursor to polymers of intrinsic microporosity (2011)

A novel triptycene-containing A–B monomer bearing both phenazine activating aromatic <italic>o</italic>-dichloride and a catechol group was synthesized. This monomer is the first example of an A–B monomer used for the synthesis of a novel polymer of intrinsic microporosity (PIM). The synthesized polymer demonstrated good porosity, thermal stability and solubility in common organic solvents.
Semantic 3D Occupancy Mapping through Efficient High Order CRFs (2017)

Semantic 3D mapping can be used for many applications such as robot navigation and virtual interaction. In recent years, there has been great progress in semantic segmentation and geometric 3D mapping. However, it is still challenging to combine these two tasks for accurate and large-scale semantic mapping from images. In the paper, we propose an incremental and (near) real-time semantic mapping system. A 3D scrolling occupancy grid map is built to represent the world, which is memory and computationally efficient and bounded for large scale environments. We utilize the CNN segmentation as prior prediction and further optimize 3D grid labels through a novel CRF model. Superpixels are utilized to enforce smoothness and form robust P N high order potential. An efficient mean field inference is developed for the graph optimization. We evaluate our system on the KITTI dataset and improve the segmentation accuracy by 10% over existing systems.

Measures of fat distribution as determinants of serum lipids in healthy volunteers consuming a uniform standardized diet (1988)

The relation was investigated between body fat topology and serum lipoproteins in healthy, nonobese men and women. Twenty-four men and 24 women consumed a standardized affluent diet for 17 days. Serum was obtained after 14 and 17 days. Regression coefficients of lipids and lipoproteins with age, body mass index, measures of fat distribution, and estimates of fat areas at a cross-section of the body at the level of the umbilicus, were calculated. Waist-to-thigh circumference ratio proved to be the strongest correlate of serum lipids compared with other measures of fat distribution. Upon multiple regression analysis, the waist-to-thigh ratio proved to be a stronger predictor of total cholesterol, LDL-cholesterol and triglyceride levels in men than either age or body mass index. In women this was only true for HDL3-cholesterol. In addition, no significant relations were observed any more of age and body mass index with these serum lipids, with the exception of age for IDL-cholesterol in men. Estimates of intra-abdominal fat area showed in general a stronger correlation with serum lipids than estimates of subcutaneous fat area. It is concluded that, in non-obese subjects, fat distribution is a stronger determinant of serum lipids than either body mass index or age.
Puromycin-resistant biosynthesis of a specific outer-membrane lipoprotein of Escherichia coli (1976)

The reported puromycin resistance of the in vivo biosynthesis of a specific outer-membrane lipoprotein of Escherichia coli was further investigated. The biosynthetic machinery making the lipoprotein was made more accessible to puromycin by disruption of the cell structure using ethylenediaminetetracetate or toluene, and finally in an in vitro protein biosynthesis system using polyribosomes. Puromycin sensitivity of overall protein synthesis increased by about 10-fold for each method of disruption of the cell structure; 50% inhibitions were obtained at 330, 35, 2.7, and 0.22 mug of puromycin per ml for intact cells, ethylenediaminetetraacetate-treated cells, toluene-treated cells, and the polyribosome system, respectively. However, the lipoprotein biosynthesis remained more resistant to puromycin than the biosynthesis of other proteins in all systems tested. These results strongly suggest that puromycin resistance of the lipoprotein biosynthesis is due to an intrinsic property of the lipoprotein biosynthetic machinery.
