Exposure to cell phone radiations produces biochemical changes in worker honey bees (2011)

The present study was carried out to find the effect of cell phone radiations on various biomolecules in the adult workers of Apis mellifera L. The results of the treated adults were analyzed and compared with the control. Radiation from the cell phone influences honey bees' behavior and physiology. There was reduced motor activity of the worker bees on the comb initially, followed by en masse migration and movement toward "talk mode" cell phone. The initial quiet period was characterized by rise in concentration of biomolecules including proteins, carbohydrates and lipids, perhaps due to stimulation of body mechanism to fight the stressful condition created by the radiations. At later stages of exposure, there was a slight decline in the concentration of biomolecules probably because the body had adapted to the stimulus.

Improved delay root-Nyquist filters for symbol synchronisation in PCS receivers (2002)

With the impending introduction of personal communications systems (PCS) which use hierarchical, multi-rate cellular structures, minimum complexity demodulators will be essential to ensure low-cost mobile terminals. The demodulator complexity may be reduced through the integration of matched filter (MF) and symbol timing recovery (STR) functions. This paper proposes and discusses a number of methods for the design of minimum complexity MFs which incorporate a fractional-sample delay (FSD) for the purpose of symbol timing synchronisation. In particular the down-link (base station to mobile) is considered where near-ideal transmit filters are used and the receive filter's complexity is minimised. The results show that the use of system performance metrics such as ISI and SNR in the filter design procedure can lead to significant performance improvements compared with more traditional methods.
Thermodynamic model for tricritical points in ternary and quaternary fluid mixtures (1974)

The properties of a phenomenological model of the Landau type (free energy expanded in powers of an order parameter) are worked out with special reference to published experimental data on tricritical points in three- and four-component fluid mixtures. When properly interpreted, the model is in good qualitative agreement with experiment. Suggestions are made for possible experimental measurements of the tricritical exponents. The model is also used to discuss the relation between these tricritical points (which are characterized by three phases becoming identical simultaneously) and other ``higher-order'' critical points, in particular the tricritical points observed in metamagnets, He3–He4 mixtures, etc.
A Method for Distributed Pipeline Burst and Leakage Detection in Wireless Sensor Networks Using Transform Analysis (2014)

Bursts and leakages have turned out to be one of the most frequent malfunctions in liquid pipeline distribution systems. In recent years, the issue has gained a lot of attention in research community due to associated financial costs, environmental hazards, and safety considerations. Wireless sensor network (WSN) based leakage detection and localization can provide an exceptional level of operational efficiency, safety assurance, and real-time parametric view of the entire pipeline network. In this paper, we propose a transient pressure wave based technique coupled with wavelet analysis to achieve reliable detection and localization of abrupt bursts and leakages. The presented technique uses the information carried in the transient pressure signal. A specific pattern is induced on the pressure traces within the pipeline due to leak; we use wavelet analysis to detect these local singularities. The proposed algorithm is distributed in nature and run on low power sensor nodes. The algorithm is deployed in field on a custom pipeline test bed and performance results are documented for various testing scenarios. A comparison of proposed wavelet technique with other widely used methods has been carried out. The technique provides more than 90% accuracy in a number of deployment scenarios for high noise generating long pipeline networks.
Polyfluoroalkyl compounds of silicon. Part VIII. Reactions of silanes with vinyl fluoride and with 1-chloro-2-fluoroethylene (1967)

Photochemical reactions of trichlorosilane, methyldichlorosilane, or trimethylsilane with vinyl fluoride gave the corresponding 2-fluororoethylsilanes (90–95% yields), hydrolysis or pyrolysis of which occurred viaβ-elimination of fluorine. The photochemical reaction of trichlorosilane with 1-chloro-2-fluoroethylene gave both 1:1 adducts. These were reduced by further reaction with silanes (SiHCl3, MeSiHCl2, or Me3SiH) to give the isomeric fluoroethyltrichlorosilanes; abstraction of β-chlorine occurred 3·5 times as readily as abstraction of α-chlorine. Hydrolysis of CH2F·CHCl·SiCl3 and CH2Cl·CHF·SiCl3 occurred viaβ-elimination of halogen to give vinyl chloride and vinyl fluoride, respectively. Trimethylsilane reacted with 1-chloro-2-fluoroethylene to give chlorotrimethylsilane, 2-chloro-1-fluoroethyltrimethylsilane, and 1-fluoroethyltrimethylsilane. The recovered olefin contained vinyl fluoride.
Synthesis of Graphene Oxide using Modified Hummers Method: Solvent Influence (2017)

The aim of this study is to study the influence of different solvents on the structure and electrical properties of graphene oxide. GO was obtained from graphite flakes by using modified hummers method in which different from conventional hummer's method. In this method, the experiment was synthesized without sodium nitrate (NaNO3) and ice bath, but carried out at room temperature. Prepared GO powders were then dissolved into different solvents, namely acetone and ethanol. Then spin-coated onto silicon wafer and IDE to produce acetone-GO (A-GO) and ethanol-GO (E-GO). SEM result shows that several square micron GO were obtained. In addition, due to the large agglomerates and contact between the flakes in E-GO sample, current-voltage pattern indicated the E-GO produced higher current flow than A-GO. Meanwhile, GO characterized using FTiR shows that both samples contain several functional groups such as hydroxyl, epoxy, carboxyl and carbonyl. Besides that, due to the lower diffraction peak of A-GO, XRD result shows the interlayer spacing of A-GO sample is slightly higher than E-GO sample.
Deterministic Actors (2019)

Actors have become widespread in programming languages and programming frameworks focused on parallel and distributed computing. While actors provide a more disciplined model for concurrency than threads, their interactions, if not constrained, admit nondeterminism. As a consequence, actor programs may exhibit unintended behaviors and are less amenable to rigorous testing. We show that nondeterminism can be handled in a number of ways, surveying dataflow dialects, process networks, synchronous-reactive models, and discrete-event models. These existing approaches, however, tend to require centralized control, pose challenges to modular system design, or introduce a single point of failure. We describe “reactors,” a new coordination model that combines ideas from several of the aforementioned approaches to enable determinism while preserving much of the style of actors. Reactors promote modularity and allow for distributed execution. By using a logical model of time that can be associated with physical time, reactors also admit control over timing.
Experiences with ATM Equipments and Network Operation (1996)

There are ATM nodes from several vendors in the market and some operators even are offering public ATM services. However, in order to really make a breakthrough of ATM we must develop ATM applications which are acceptable also by others than computerwizards. Our paper gives an outline of the ATM evolution from separate nodes to real and practical services utilizing ATM technology. One of the most prominent experiences of current situation is continuously evolving standards. First adopters have faced a dilemma of never ending software and hardware updates. Although we may except that Internet will be upgraded to ATM because of increasing capacity and quality requirements, the definitive role of ATM in the whole network architecture is still shrouded in mystery, and a lot of practical and theoretical questions are open.
Redox Capacitive Assaying of C-Reactive Protein at a Peptide Supported Aptamer Interface (2018)

Electrochemical immunosensors offer much in the potential translation of a lab based sensing capability to a useful "real world" platform. In previous work we have introduced an impedance-derived electrochemical capacitance spectroscopic analysis as supportive of a reagentless means of reporting on analyte target capture at suitably prepared mixed-component redox-active, antibody-modified interfaces. Herein we directly integrate receptive aptamers into a redox charging peptide support in enabling a label-free low picomolar analytical assay for C-reactive protein with a sensitivity that significantly exceeds that attainable with an analogous antibody interface.
Ultrastructural immunocytochemical localization of endogenous 1,25-dihydroxyvitamin D3 and its receptors in osteoblasts and osteocytes from neonatal mouse and rat calvaria. (1987)

Immunoreactivity to 1,25-dihydroxyvitamin D3 receptors and endogenous 1,25-dihydroxyvitamin D3 (1,25(OH)2D3) were studied in osteoblasts and osteocytes from calvaria of neonatal mice and rats by immunocytochemistry with the use of ultrathin sections obtained by cryo-ultramicrotomy. Tissue samples were fixed in glutaraldehyde, postfixed in osmium tetroxide and frozen under liquid nitrogen. 1,25(OH)2D3 and 1,25(OH)2D3 receptor-like immunoreactivities were observed in osteoblasts and osteocytes. In both types of cell, 1,25(OH)2D3 and its receptors were similarly located in the cytoplasmic matrix but not in organelles, and mainly in the nucleus (primarily in the chromatin and sometimes near the nuclear membrane or in the nucleolus). Reaction products, however, were never seen at the plasma membrane level. These results provide immunocytological evidence for the presence of 1,25(OH)2D3 and its receptors in osteoblasts and osteocytes. The similar localization of the hormone and its receptors in osteoblasts and osteocytes supports the hypothesis of a direct action of 1,25(OH)2D3 in these bone cells. The fact that the main localization of 1,25(OH)2D3 receptors was nuclear, implies, as postulated for other steroid receptors, that 1,25(OH)2D3 receptors occur primarily in the nucleus.
Distributed Scheduling in a Time-Varying Channel (2005)

This paper studies distributed scheduling in a wireless network with a time-varying channel. The delay-throughput performance of distributed scheduling is compared to that of centralized scheduling based on proportional fairness. The relative performance of a distributed scheduling scheme depends on whether the channel is memoryless or time-correlated. Distributed scheduling achieves a good delay-throughput performance relative to proportional fair scheduling in a time-correlated channel. Delay-differentiation in general requires joint power control and scheduling.

beta-Catenin mutation is a frequent cause of Wnt pathway activation in gastric cancer. (2002)

Studies of Wnt activation in gastric cancer have yielded conflicting results. The goals of this study were to determine the frequency of Wnt pathway activation and beta-catenin mutation in these tumors. Three hundred eleven gastric cancers were examined for beta-catenin expression by immunostaining and dissected using laser capture microscopy to obtain DNA from those tumors with nuclear beta-catenin. Exon 3 of beta-catenin was amplified using PCR and sequenced. Ninety gastric cancers (29%) displayed nuclear beta-catenin. DNAs from 73 tumors were amplified and sequenced; 19 (26%) contained mutations in exon 3 of beta-catenin, whereas no mutations were detected in 19 tumors negative for beta-catenin nuclear staining (P < 0.05). Most mutations were adjacent to or abolished known regulatory phosphorylation sites. Mutations in exon 3 of beta-catenin are common in gastric cancer that display nuclear beta-catenin. These results suggest that Wnt pathway activation contributes to carcinogenesis in a subset of gastric adenocarcinomas.
Teflon-Coated Silicon Microreactors: Impact on Segmented Liquid−Liquid Multiphase Flows (2011)

We describe fluoropolymer modification of silicon microreactors for control of wetting properties in chemical synthesis applications and characterize the impact of the coating on liquid-liquid multiphase flows of solvents and water. Annular flow of nitrogen gas and a Teflon AF (DuPont) dispersion enable controlled evaporation of fluoropolymer solvent, which in turn brings about three-dimensional polymer deposition on microchannel walls. Consequently, the wetting behavior is switched from hydrophilic to hydrophobic. Analysis of microreactors reveals that the polymer layer thickness increases down the length of the reactor from ∼1 to ∼13 μm with an average thickness of ∼7 μm. Similarly, we show that microreactor surfaces can be modified with poly(tetrafluoroethylene) (PTFE). These PTFE-coated microreactors are further characterized by measuring residence time distributions in segmented liquid-liquid multiphase flows, which display reduced axial dispersion for the coated microreactors. Applying particle image velocimetry, changes in segment shape and velocity fluctuations are observed resulting in reduced axial dispersion. Furthermore, the segment size distribution is narrowed for the hydrophobic microreactors, enabling further control of residence distributions for synthesis and screening applications.
Electrical response of a slim-loop-ferroelectric ceramic compressed by shock waves (1978)

Shock reverberation experiments were performed on electrically biased specimens of the slim-loop-ferroelectric ceramic (Pb0.715Ba0.285)0.991(Zr0.707Ti0.293) 0.981Bi0.019O3, and a simple model was fitted to the observed electrical response. It was found that the material could be described as a linear reversible dielectric and that the reciprocal of the permittivity is linearly related to the shock stress.
Suppression of microbunching instability using bending magnets in FEL linacs (2013)

The microbunching instability driven by collective effects of the beam inside an accelerator can significantly degrade the final electron beam quality for free electron laser (FEL) radiation.In this letter, we propose an inexpensive scheme to suppress such an instability in accelerators for next generation FEL light sources.Instead of using an expensive device such as a laser heater or RF deflecting cavities, this scheme uses longitudinal mixing associated with the transverse spread of the beam through bending magnets inside the accelerator transport system to suppress the instability.The final uncorrelated energy spread increases roughly by the current compression factor, which is important in seeded FEL schemes in order to achieve high harmonic short wavelength X-ray radiation.

Biomechanical Assessment of Rucksack Shoulder Strap Attachment Location: Effect on Load Distribution to the Torso (2001)

The objective of this study was to conduct biomechanical testing of pack component options to determine the optimal location for the lower attachment of the shoulder strap for the Clothe the Soldier (CTS) Integrated Patrol Pack and Rucksack. A model of a 50th percentile male torso has been split transversely at T12/L1 and instrumented with two six degree of freedom load cells. The shoulder area of the manikin was instrumented with Fscan(Trademark) sensors to record the contact pressure distribution in the axilla (armpit) and anterior of the shoulder under the shoulder strap. A 25 kg fixed payload was used for all test configurations. Waist belt, load lifter and shoulder strap tensions were constant during testing. Output variables were reaction forces at T12/L1, waist belt lifting force, average and peak contact pressures about the shoulder. These were examined as a function of the attachment point location and as a function of the angle the shoulder strap made with respect to the body long axis. Strap angles above 30 degrees resulted in peak axilla contact pressures ranging from 35 to 64 kPa. At strap angles less than 24 degrees, anterior shoulder peak pressures of > 32 kPa were recorded. These two effects determined the upper and lower bounds of an optimal range of 24 to 30 degrees with respect to the vertical axis of the body. These results cannot be extrapolated to other attachment locations that were not tested and pertain only to the type of strap tested.
HIGHER ANTI‐HEPATITIS B RESPONSE WITH COMBINED DTPw‐HBV VACCINE COMPARED WITH SEPARATE ADMINISTRATION IN HEALTHY INFANTS AT 3, 4 AND 5 MONTHS OF AGE IN SLOVAKIA (2001)

To help achieve universal infant immunisation against hepatitis B, the World Health Organisation has recommended the development of a combined diphtheria, tetanus and pertussis (DTP) and hepatitis B vaccine (HBV). The advantages come from the fact that DTP coverage is estimated to be over 80% worldwide and a combined DTP-HB vaccine would increase the coverage of HBV. This study was conducted to compare the immunogenicity and reactogenicity of a combined DTP-HB vaccine with separate, concomitant administration of DTP and HBV vaccines. One hundred and twenty infants were randomised in a 1:1 ratio to one of the two vaccination regimens, given as three injections at approximately 3, 4 and 5 months of age. The only difference in immunogenicity between the two regimens was a higher antibody response to hepatitis B in the group given the combined vaccine, possibly as a result of the adjuvant effect of the whole cell pertussis component of the DTP vaccine. Both vaccine regimens were well tolerated.
Expanded Multilocus Sequence Typing for <i>Burkholderia</i> Species (2009)

PCR primers targeting loci in the current Burkholderia cepacia complex multilocus sequence typing scheme were redesigned to (i) more reliably amplify these loci from B. cepacia complex species, (ii) amplify these same loci from additional Burkholderia species, and (iii) enable the use of a single primer set per locus for both amplification and DNA sequencing.
CREB Binding Protein Is a Coactivator for the Androgen Receptor and Mediates Cross-talk with AP-1 (1998)

Androgens are critical in the development and maintenance of the male reproductive system and important in the progression of prostate cancer. The effects of androgens are mediated through the androgen receptor (AR), which is a ligand-modulated transcription factor that belongs to the nuclear receptor superfamily. In addition to its ability to activate transcription from androgen response elements, AR can inhibit activator protein-1 (AP-1) activity, composed of Jun and Fos oncoproteins, in a ligand-dependent manner. Conversely, when activated, AP-1 can block AR activity. We found that CREB (cAMP response element-binding protein) binding protein (CBP) had a direct role in both of these activities of AR. CBP significantly increased the ability of endogenous AR in LNCaP cells to activate transcription from an AR-dependent reporter construct. On the other hand, repression of AR activity by treatment of LNCaP cells with an activator of AP-1 was largely relieved when CBP was ectopically expressed. AR and CBP can physically interact in vitro as was shown in glutathione S-transferase pulldown assays. Whereas both the N terminus and ligand-binding domain of AR can interact with CBP, a short region in the N terminus of CBP is required for these interactions. As opposed to the interaction of CBP with other nuclear receptors studied so far, CBP-AR interactions were not affected by ligand binding to AR in vitro. These data suggest that CBP is a coactivator for AR in vivo and that the transcriptional interference between AR and AP-1 is the result of competition for limiting amounts of CBP in the cell.
A Persistent Pattern of Varying Pituitary Responsivity to Exogenous Growth Hormone (GH)-Releasing Hormone in GH-Deficient Children: Evidence Supporting Periodic Somatostatin Secretion* (1988)

The pattern and degree of variation in pituitary responsivity to GHRH was examined in four GH-deficient children (two boys and two girls, aged 4 3/12 to 10 4/12 yr). All children were studied before and on multiple (three to six per child) occasions during long term GHRH therapy (1 or 2 micrograms/kg, sc, every 3 h) in an identical fashion. Each study comprised withdrawal of blood for serum GH measurements every 20 min between 2000 and 0800 h. All subjects received GHRH at 2000, 2300, 0200, and 0500 h as well as at 0800, 1100, 1400, and 1700 h throughout the long term treatment period (6-18 months). Although all children had low level (less than 7.0 micrograms/L) pulsatile GH secretion during baseline studies, the maximal peak values occurred at times other than 0500 h. Before GHRH treatment, serum GH levels rose significantly in response to 91% (62 of 68) of the GHRH doses administered. GH pulse amplitudes varied throughout the studies in all children, and this variability persisted despite 1300-3600 consecutive doses in each child. In all 17 study periods the highest serum GH concentration occurred shortly after the 0500 h GHRH dose. The mean peak GH concentration after the 0500 h GHRH dose [18.4 +/- 3.5 (+/- SE) micrograms/L] was significantly higher than those after the 2000 h (5.3 +/- 1.0 micrograms/L; P = 0.0001), 2300 h (7.4 +/- 2.1 micrograms/L; P = 0.0003), and 0200 h (10.9 +/- 2.5 micrograms/L; P = 0.011) doses. These results demonstrate that the responsivity of the pituitary to GHRH varies throughout the night in some GH-deficient children. There appears to be a direct relationship between the time of night and the degree of pituitary responsivity to GHRH. We suggest that this variable responsivity may be due to intermittent hypothalamic somatostatin secretion.
Deficiency of brain synaptic dystrophin in human duchenne muscular dystrophy (1995)

Abstract Duchenne muscular dystrophy (DMD) is characterized by a defect in dystrophin, a high molecular weight protein that is located predominantly in muscle, but which has been detected in brain. Brain dystrophin has been localized to the synapse, in the postsynaptic density (PSD), and is absent in the mdx mouse, an animal model of human DMD. To define the potential pathogenic role of dystrophin deficiency in cognitive impairment, we examined the protein in human DMD brain. The 427‐kd dystrophin was absent in the PSD from DMD brain, but was normally expressed in the brain from an age‐matched control subject. Our findings indicate that dystrophin is deficient in human DMD cortical synapses and provide a potential pathogenic mechanism for cognitive impairment.
