Wide band instantaneous coverage receiver concept for ALMA (2019)

We propose concept of frequency array receiver. Receiver input beam will be quasi-optically frequency multiplexed on several mixer pixels. All individual mixers will be operated simultaneously creating very large input bandwidth covering several atmospheric windows in high frequency resolution. This system allows to combine large bandwidth advantage of direct detecting with high frequency resolution of heterodyne system. We will discuss initial system concept, and report on mixer designs and their performance for building elements. In particularly we report DSB noise temperature below hf/k level at 260GHz mixer prototype. Sensitivity of such system in presents of atmospheric background will be evaluated.
End-to-end routing behavior in the internet (2006)

The large-scale behavior of routing in the Internet has gone virtually without any formal study, the exception being Chinoy's analysis of the dynamics of Internet routing information [Ch93]. We report on an analysis of 40,000 end-to-end route measurements conducted using repeated "traceroutes" between 37 Internet sites. We analyze the routing behavior for pathological conditions, routing stability, and routing symmetry. For pathologies, we characterize the prevalence of routing loops, erroneous routing, infrastructure failures, and temporary outages. We find that the likelihood of encountering a major routing pathology more than doubled between the end of 1994 and the end of 1995, rising from 1.5% to 3.4%. For routing stability, we define two separate types of stability, "prevalence," meaning the overall likelihood that a particular route is encountered, and "persistence," the likelihood that a route remains unchanged over a long period of time. We find that Internet paths are heavily dominated by a single prevalent route, but that the time periods over which routes persist show wide variation, ranging from seconds up to days. About 2/3's of the Internet paths had routes persisting for either days or weeks. For routing symmetry, we look at the likelihood that a path through the Internet visits at least one different city in the two directions. At the end of 1995, this was the case half the time, and at least one different autonomous system was visited 30% of the time.
Educators' responses to changes in the health care system. (1997)

A survey was conducted to identity programmatic/curricular changes made by New York state nursing schools in response to the changing health care environment and to identity the success of job placement for new graduates. Data were reported for 84 programs. Respondents indicated that innovative curriculum initiatives were employed, such as increasing community experiences and primary health care content. Opportunities for job placement were enhanced by a number of strategies, including resume writing and job interviewing workshops.
Associative face co-occurrence networks for recommending friends in social networks (2010)

In social network services, which have become widely used as an important tool to share rich information, making new friends is the most basic functionality to enable users to take advantage of their social networks. However, in current social network services, making new friends still relies on manually browsing networks of current friends. Even though the most services try to automatically suggest new friends, users can hardly accept those suggestions without any meaningful explanation of relationships. To deal with this issue, in this paper, we look into personal photos as an additional source for social network analysis and analyze the potential of name tagging in the photos for applying to friend recommendations. Moreover, we propose a new compact data structure, namely Face Co-Occurrence Networks (FCON), for photo networks storing crucial and quantitative information about people appearance in photos. By incorporating with FCON, we discover strong associative relationships among people and recommend reliable social friends. Experimental results demonstrate the feasibility of our method for recommending friends in social network services.
High-sensitivity nanosensors for biomarker detection (2011)

High sensitivity nanosensors utilize optical, mechanical, electrical, and magnetic relaxation properties to push detection limits of biomarkers below previously possible concentrations. The unique properties of nanomaterials and nanotechnology are exploited to design biomarker diagnostics. High-sensitivity recognition is achieved by signal and target amplification along with thorough pre-processing of samples. In this tutorial review, we introduce the type of detection signals read by nanosensors to detect extremely small concentrations of biomarkers and provide distinctive examples of high-sensitivity sensors. The use of such high-sensitivity nanosensors can offer earlier detection of disease than currently available to patients and create significant improvements in clinical outcomes.
Immunodepression after major surgery in normal patients. (1975)

Multiple parameters of in vivo and in vitro immune function were measured serially before, during, and following nephrectomy in 12 normal renal transplant donors. All in vitro functions studied (total blood lymphocyte count, B-cell count, T-cell count, mitogen blastogenic response, and mixed leukocyte reactivity as both responder and stimulator) decreased on induction of anethesia and continued to fall during and after operation to reach a low point on the evening after nephrectomy. Depth of depression and rate of recovery varied with the individual function, but all were near normal by the fifth postoperative day. The in vivo delayed hypersensitivity response to cutaneously administered recall antigens declined more gradually and was still falling at the fifth postoperative day. Return of preoperative skin response was delayed, being complete for streptokinase/streptodornase (SK/SD) by 10 to 14 days but incomplete as long as 2 to 3 weeks for mumps and Candida antigens. Serum immunoglobulins did not change. These findings suggest incomplete correlation among the responses to the commonly used in vitro assays of cellular immunity and poor correlation with the in vivo tests. Although surgery and anesthesia results in measurable depression of immune response, clinically significant problems did not arise in these patients.
Structured laser gain-medium by new bonding for power micro-laser (2017)

In this work, we have compared the Q-switched performance of single rod crystal to a newly developed distributed face cooling structure. This structure was made by surface activated bonding technology and allowed to combine transparent heatsink to a gain crystal at room temperature. The Sapphire and Nd<sup>3+</sup>:YAG crystal plates were combined in this fashion to produce eight crystal chip which was further used to obtain Q-switch pulses with Cr<sup>4+</sup>:YAG crystal as saturable absorber. Energy of 9 mJ and pulse duration of 815 ps were achieved. Although the energy obtained with single rod system was 10 mJ, the degradation of the beam prevents such crystal to be used in further applications. This is the first demonstration of distributed face cooling system outperformed conventionally single rod system.

Factors Affecting the Gelation Properties of Hydrolyzed Sunflower Proteins (1997)

ABSTRACT The effects of temperature and several chemicals on gelation time and strength of gels formed by heating (pH 8) 5% solutions of trypsin hydrolyzed sunflower proteins were studied by dynamic rheological methods. The storage modulus reached a maximum at 80°C. Ca 2 Cl (and NaCl at > 0.2M) accelerated gelation and weakened the gel. NaCOCH 3 Na 2 SO 4 and NaSCN decreased the storage modulus. Urea decreased gelstrength and at high concentrations slowed gelation. Time for gelation diminished and gel strength increased with increasing mercaptoethanol concentration up to 0.1M. Propylene glycol at 5–20% concentrations accelerated gelation and at 5% also increased gel strength. Trypsin hydrolyzed sunflower proteins could be useful in products requiring strong gels at high temperatures.

Tunable Hybrid Fano Resonances in Halide Perovskite Nanoparticles (2018)

Halide perovskites are known to support excitons at room temperatures with high quantum yield of luminescence that make them attractive for all-dielectric resonant nanophotonics and meta-optics. Here we report the observation of broadly tunable Fano resonances in halide perovskite nanoparticles originating from the coupling of excitons to the Mie resonances excited in the nanoparticles. Signatures of the photon-exciton (" hybrid") Fano resonances are observed in dark-field spectra of isolated nanoparticles, and also in the extinction spectra of aperiodic lattices of such nanoparticles. In the latter case, chemical tunability of the exciton resonance allows reversible tuning of the Fano resonance across the 100 nm bandwidth in the visible frequency range, providing a novel approach to control optical properties of perovskite nanostructures. The proposed method of chemical tuning paves the way to an efficient control of emission properties of on-chip-integrated light-emitting nanoantennas.
Involvements of fibronectin and lysophosphatidylcholine for selective binding of C-reactive protein. (1991)

C-reactive protein (CRP) has been reported to deposit only to inflammatory sites, but not to normal sites. In present paper, we investigated involvements of fibronectin and lysophosphatidylcholine (lyso-PC) as responsible for this selectivity. In ELISA assay, CRP was found to bind to immobilized fibronectin with dose dependency, only in the presence of Ca2+ ions. Addition of 5 mM EDTA allowed CRP to abolish this binding. However, it could not be inhibited neither by phosphorylcholine nor by heparin. On the other hand, CRP could aggregate liposome consisted of lyso-PC and phosphatidylcholine (PC), but not that consisted of PC alone. Aggregation was found to be maximum when liposome with lyso-PC/PC molar ratio of 0.3 was used. Similar result was also observed in binding study with peroxidase-labelled CRP. In addition, phospholipase A2 treatment of liposome consisted of PC alone induced 3-fold higher binding than that found with untreated one. Ca2+ ions were required for binding to liposome.
Human Protein C inhibits selectin-mediated cell adhesion: role of unique fucosylated oligosaccharide (1994)

The human anticoagulant factor, Protein C, is a plasma glycoprotein that has reported anti-ischaemic and anti-inflammatory properties. To explore potential mechanisms for these reported activities, we examined the effect of Protein C on the process of cell adhesion to vascular endothelial cells, which plays a critical role during inflammatory responses. We show that both human plasma-derived and human cell-produced recombinant Protein C inhibit E-selectin-mediated cell adhesion. This effect was not mediated through the serine protease activity of Protein C, but through its carbohydrates. Using oligosaccharides isolated from human cell-produced Protein C, we have defined a polylactosamine structural determinant that inhibits adhesion. This uncharged determinant appears to be a more potent ligand for E-selectin than the sialylated Lewis X antigen. Our data suggest a potential mechanism for the reported anti-inflammatory effects of Protein C and describe a new ligand for selectin-mediated adhesion.
The Children's Bill - a suitable vehicle for children's comprehensive social security rights : social security (2003)

Extracted from text ... The Children's Bill - A suitable vehicle for children's comprehensive social security rights by Patricia Martin South Africa has taken a bold step to giving legal effect to children's rights in a comprehensive manner. The draft Children's Bill (the Bill), originally meant to replace the Child Care Act of 1983, is a holistic piece of legislation that incorporates a host of wide-ranging laws relating to children. It includes a network of provisions on, among other things, parental rights and responsibilities, children in especially difficult circumstances, prevention and early intervention, and social security for children. Of particular note is that ..
Effect of multifunctional comonomers on the properties of poly(ethylene terephthalate) copolymers (2002)

Abstract The properties of poly(ethylene terephthalate) (PET) and its copolymers containing 0.04–0.15 mol% of pentaerythritol and trimethylolethane (TME) have been investigated. The molecular weight of the copolymers increased with comonomer content, and this effect was observed significantly with pentaerythritol copolymers, resulting in broad molecular weight distribution. The comonomer effect on the mechanical properties was small. The shear viscosity of the copolymers showed shear thinning within the experimental shear rate range. The crystallization rate and birefringence of the fibres containing 0.103 mol% pentaerythritol increased with the spin draw ratio, whereas they decreased with comonomer content. © 2002 Society of Chemical Industry
The Impact of Erythrocyte Lysing Procedures on the Recovery of Hematopoietic Progenitor Cells in Flow Cytometric Analysis (2005)

Since preanalytic lysing of erythrocytes remains critical in flow cytometry, we investigated the influence of four lysing procedures on the quantification of leukocyte and CD34+ cells in hematopoietic cell transplants (HCTs). Samples were derived from stem cell-enriched mobilized whole blood collected by apheresis (unselected) and immunologically purified stem cell products (selected) and were measured using the dual-platform (2-PF) method with two flow cytometric systems. Additionally, cells were measured by a volume-based technique (single platform [1-PF]). Results were identical in the 2-PF mode (unselected HCTs, r = 0.998; selected HCTs, r = 0.999). In comparison with the 2-PF results, the single-platform (1-PF) measurements revealed a mean decrease of 59.5% for CD34+ cells (50.8% for CD45+ cells) in unselected HCTs and a mean decrease of 52% for CD34+ cells (49.8% for CD45+ cells) in selected HCTs. In order to check the accuracy of cell quantification using the 1-PF method, leukocyte reference values from hematology counter results were compared with flow cytometric (1-PF)-counted nucleated cells. That analysis revealed good congruency, with r = 0.998 for unselected HCTs and r = 0.999 for selected HCTs. In conclusion, all lysing procedures that we used induced substantial loss of leukocytes and CD34+ cells. As demonstrated by the high accuracy of the 1-PF technique, all erythrocyte lysing procedures caused significant cell loss, which led to inconsistent counting of CD34+ cells in nonvolumetric flow cytometric (2-PF) protocols.
Service Level Agreement Characteristics of Monitoring Wireless Sensor Networks for Water Resource Management (SLAs4Water) (2017)

One of the most important characteristics of a Service Level Agreement (SLA) when discussing about Monitoring Wireless Sensor Networks (MWSNs) is its effectiveness in assuring business success, a high provider profit, an increased level of client satisfaction and trust. In order to ensure that these goals will be achieved the provider of the MWSN must define some parameters that characterize the Service Level Agreement that occurs between MWSN provider and the MWSN customer. This paper addresses a solution behind an efficient and effective Service Level Agreement (SLA) design and implementation related to a Monitoring Wireless Sensor Network (MSN) and applies the SLA in the case of water resources management. The characteristics of the SLA in place between the MWSN provider and the MWSN customer must be defined by taking into consideration various parameters that are particular to the MWSN such as routing algorithms, recovery from failure, monitoring and reporting aspects. An appropriate definition of a SLA contract helps identify the responsibilities of both the provider and customer of the Monitoring Wireless Sensor Network (MSN) and makes the interaction between the provider and customer easier.
Specificity of human cathepsin S determined by processing of peptide substrates and MHC class II-associated invariant chain (2006)

Cathepsin S (CatS) is a lysosomal cysteine protease of the papain family, the members of which possess relatively broad substrate specificities. It has distinct roles in major histocompatibility complex (MHC) class II-associated peptide loading and in antigen processing in both the MHC class I and class II pathways. It may therefore represent a target for interference with antigen presentation, which could be of value in the therapy of (auto)immune diseases. To obtain more detailed information on the specificity of CatS, we mapped its cleavage site preferences at subsites S3-S1' by in vitro processing of a peptide library. Only five amino acid residues at the substrate's P2 position allowed for cleavage by CatS under time-limited conditions. Preferences for groups of amino acid residues were also observed at positions P3, P1 and P1'. Based on these results, we developed highly CatS-sensitive peptides. After processing of MHC class II-associated invariant chain (Ii), a natural protein substrate of CatS, we identified CatS cleavage sites in Ii of which a majority matched the amino acid residue preference data obtained with peptides. These observed cleavage sites in Ii might be of relevance for its in vivo processing by CatS.
A wideband spectrum sensing method for cognitive radio using sub-Nyquist sampling (2011)

Spectrum sensing is a fundamental component in cognitive radio. A major challenge in this area is the requirement of a high sampling rate in the sensing of a wideband signal. In this paper a wideband spectrum sensing model is presented that utilizes a sub-Nyquist sampling scheme to bring substantial savings in terms of the sampling rate. The correlation matrix of a finite number of noisy samples is computed and used by a subspace estimator to detect the occupied and vacant channels of the spectrum. In contrast with common methods, the proposed method does not need the knowledge of signal properties that mitigates the uncertainty problem. We evaluate the performance of this method by computing the probability of detecting signal occupancy in terms of the number of samples and the SNR of randomly generated signals. The results show a reliable detection even in low SNR and small number of samples.
Altered circadian cortisol secretion in Alzheimer's disease: Clinical and neuroradiological aspects (2001)

We determined circadian salivary cortisol levels in 18 outpatients affected by probable Alzheimer's disease (AD) and looked for a possible correlation with both cognitive impairment and brain CT scan findings. The diagnosis of probable AD was made according to the NINCDS-ADRDA criteria. The severity of cognitive impairment was quantified using the Mini Mental State Examination (MMSE) and the Global Deterioration Scale (GDS). Cortisol levels were measured on saliva samples collected at 08:00 AM and 08:00 PM. For each sample, a duplicate cortisol measurement was performed on 50 microl of saliva by means of a modified commercial radioimmunoassay kit. At the same time, 11 of the 18 AD patients enrolled also underwent a brain CT scan to estimate cerebral atrophy by using linear indexes. The mean value of cortisol levels was significantly higher in AD patients than in controls at both the morning and the evening measurements, and the circadian fluctuation of cortisol was less marked in AD patients than in controls, although this difference did not reach statistical significance. Morning cortisol levels were significantly correlated to both the MMSE and the GDS scores. A significant correlation was also found between morning cortisol levels and all the cerebral atrophy indexes. By contrast, no correlation was observed between evening cortisol levels or cortisol circadian fluctuations and either cognitive impairment or cerebral atrophy. In conclusion, despite the potential biases deriving from the small sample and the limitations of the CT scan study, our results suggest that, in AD patients, hypercortisolemia is correlated with severity of the disease.
Methods of analysing the heat production of muscle (1937)

Abstract The initial heat production of muscle (as distinguished from the delayed heat production) occurs so rapidly that the determination of its distribution in time, particularly in relation to contraction, relaxation and the performance of mechanical work, requires special methods of analysis (see e.g. Hartree 1933). The only means hitherto found satisfactory of measuring muscle heat production has employed a thermopile and galvanometer. For the rise of temperature involved the e.m.f. developed by the thermopile is only a few microvolts, and it has not been possible to devise any really satisfactory method of amplification: the current has had to be read directly by the galvanometer. Since the current was small the galvanometer had to be sensitive, and therefore comparatively slow. This introduced the first element of delay in the measurement of the heat, that due to the galvanometer. The second was due to the thermopile, for all thermopiles hitherto employed have been rather slow in reaching the temperature of the muscle. Moreover, their heat capacity has been so large that the sensitivity of the system has been considerably less than that calculated simply from the constants of the apparatus. For all these reasons the analysis and the calibration have been performed by heating the muscle electrically during a known short interval, or “instantaneously”, and finding numerically what distribution of such heat-pulses would give the same deflexion, in time and amplitude, as the heat produced by the stimulated muscle. The method is laborious and there are various objections to it, particularly (i) the requirement that the muscle must be of uniform cross-section if it is to be uniformly heated (see Hill 19316, p. 144, Appendix II), (ii) the need of very good electrical insulation, in order to avoid leaks, and (iii) the danger of non-uniform heating in the immediate neighbourhood of the electrodes leading current to the muscle. Within limits, however, the method has fulfilled its purpose, and all significant results on the time-course of the heat production of muscle (and nerve) have been obtained with it.
