Small germanium sulfide clusters: mass spectrometry and density functional calculations (2010)

Germanium sulfide clusters were generated by laser ablation of a solid sample. The resulting molecules were analyzed in a time-of-flight mass spectrometer. In addition to atomic germanium and diatomic sulfur, the spectra exhibited evidence for the existence of clusters containing up to four germanium atoms. Unlike the more commonly observed log-normal distribution of clusters as a function of cluster size, the abundance and even the appearance of a particular cluster appeared to depend upon the likelihood of forming the cluster from a smaller molecule. The potential structures of the observed clusters were computationally investigated using a density-functional approach.
Impact of the Season of Birth on the Development of Juvenile Idiopathic Arthritis in the United States: A Nationwide Registry-based Study (2021)

Relative to the general population, children with JIA are more often born in the winter, and specifically in the month of January. These observations support the hypothesis that seasonal variations in exposures during the gestational and/or early postnatal periods may contribute to development of JIA.

Design of a 30-hp solar steam-powered turbine. Topical report (1980)

The type-selection and complete design of a 30hp turbine which operates on superheated steam are described. The steam obtains most of its energy (the latent heat of vaporization) from solar energy at approximately 100/sup 0/C (design) and is then superheated by a fuel energy source to 600/sup 0/C (design). The turbine is designed for an exit pressure of 10.086 kPa(abs) corresponding to a condenser temperature of 46/sup 0/C (115/sup 0/F), as required for air-cooled condensers. The turbine selected is of counter-rotation radial outflow design, employing 10 rows of reaction-type blading, and it operates at 15300 rpm (design). The calculated turbine efficiency at design conditions is 75%, well above the efficiency of existing steam turbines of same power and steam conditions. Extensive calculations of the turbine efficiency at off-design conditions indicate a very small deterioration in efficiency, of the order of a few percent, over the practical range of operations.

Calculation of energy absorbed in the plasma of high voltage nanosecond discharge with subnanosecond rise-time of voltage impulse (2018)

The possibility of using method for measuring the absorbed energy by means of a shunt current was considered. Experimental results of such measurements in a plasma of pulsed electric discharges excited by nanosecond voltage pulses, which are applied to a nonlinear load through long transmission line, are presented. A comparison was made with the technique of measuring the absorbed energy by means of a voltage divider and a shunt current located directly in the load.
FPGA-based Smart Camera for 3D wavelet-based image segmentation (2008)

In recent years hardware implementation of the wavelet transform for image processing has gathered significant attention. The wavelet transform is a promising tool for image processing and in particular for image compression and image segmentation. In this paper the 3D wavelet transform is used to detect moving objects or object groups as regions of interest (ROI). We propose a hardware implementation of the 2D wavelet transform, including PAL/NTSC video grabbing and Ethernet interface. It requires a low density FPGA board like V2PRO, while the 3D wavelet transform needs slightly more internal memory. Careful selection of those subbands which contain important coefficients reduces the computing power and memory requirements for video segmentation and movement detection. In addition, using the ROI mask the network transfer rate can be reduced significantly. The design is called smart camera because it delivers processed images instead of original ones.
Injectable and Pathogen‐Mimicking Hydrogels for Enhanced Protective Immunity against Emerging and Highly Pathogenic Influenza Virus (2016)

Seasonal emerging infectious diseases such as influenza A impose substantial risk and need new translational strategies to achieve active immunomodulation. Here, a novel injectable pathogen-mimicking hydrogel (iPMH) that can enhance both cellular and humoral immune responses is suggested. By the help of poly(γ-glutamic acid) that has abundant carboxylate groups and dispersion helper function, hydrophobic immunostimulatory 3-O-desacyl-4'-monophosphoryl lipid A (MPLA) molecules and viral antigens (PR8, W150) can be successfully combined as pathogen-mimicking adjuvants. Polyelectrolyte complex between the poly(γ-glutamic acid)-based adjuvants and collagens generate in situ gel-forming hydrogel at physiological temperature. When the iPMH are immunized, they act as a pathogen-mimicking (MPLA, H1N1, H5N1) immune priming center and a depot for continuous stimulation of immune system, resulting in the induction of high levels (8.5 times higher) of antigen-specific IgG titers in the sera of mice and the increased number of IFN-γ-producing cells (7.3 times higher) compared with those in the groups immunized with antigen plus clinically used aluminum gels. Following the intranasal infection of the mouse adapted virus (emerging infectious 2009 H1N1 and highly pathogenic 2006 H5N1) at 50 times the 50% lethal dose, the mice immunized with viral antigens plus iPMH exhibit 100% protective immunity against lethal virus challenge.
Evidence that a sequence similar to TAR is important for induction of the JC virus late promoter by human immunodeficiency virus type 1 Tat (1992)

A specific RNA sequence located in the leader of all human immunodeficiency virus type 1 (HIV-1) mRNAs termed the transactivation response element, or TAR, is a primary target for induction of HIV-1 long terminal repeat activity by the HIV-1-derived trans-regulatory protein, Tat. Human neurotropic virus, JC virus (JCV), a causative agent of the degenerative demyelinating disease progressive multifocal leukoencephalopathy, contains sequences in the 5' end of the late RNA species with an extensive homology to HIV-1 TAR. In this study, we examined the possible role of the JCV-derived TAR-homologous sequence in Tat-mediated activation of the JCV late promoter (Tada et al., Proc. Natl. Acad. Sci. USA 87:3479-3483, 1990). Results from site-directed mutagenesis revealed that critical G residues required for the function of HIV-1 TAR that are conserved in the JCV TAR homolog play an important role in Tat activation of the JCV promoter. In addition, in vivo competition studies suggest that shared regulatory components mediate Tat activation of the JCV late and HIV-1 long terminal repeat promoters. Furthermore, we showed that the JCV-derived TAR sequence behaves in the same way as HIV-1 TAR in response to two distinct Tat mutants, one of which that has no ability to bind to HIV-1 TAR and another that lacks transcriptional activity on a responsive promoter. These results suggest that the TAR homolog of the JCV late promoter is responsive to HIV-1 Tat induction and thus may participate in the overall activation of the JCV late promoter mediated by this transactivation.
Meeting Physical Activity Guidelines Is Associated With Reduced Healthcare Expenditure In South African Employees (2010)

PURPOSE: Recent research in South African (SA) worksites reported that 60% of employees who voluntarily participated in health screening were not meeting public health recommendations for health enhancing physical activity (PA). Of those employees who were insufficiently active, 47% and 22% had additional two and three risk factors, respectively. Therefore the main aim of this research study was to determine factors contributing to meeting PA guidelines. We also investigated the relationship between PA and healthcare costs. METHODS: Employees (n-6531) from 70 companies voluntarily participated in a wellness day which included self-reported health behaviour and health status measures. Clinical outcomes included cholesterol finger-prick test, blood pressure and Body Mass Index (BMI). Healthcare cost data were obtained for employees who were clients (n=2789) of the health insurer providing the testing, of which 409 made atleast one medical claim during the previous year. RESULTS: Participants were 36 (SD =10) years and median total annual healthcare expenditure was ZAR 3091. Employees meeting PA guidelines had significantly fewer visits to their General Practitioner (GP) (2.39 verus 2.85; p<0.001) than their inactive counterparts. This resulted in an average cost saving of ZAR 100 per year for GP visits (p<0.01). PA employees also had lower rates of hospitalisation than their sedentary counterparts, however this relationship was not significant. Resutls from a logistic regression showed that factors significantly associated with meeting PA guidelines were BMI (p<0.001), readiness to change PA (p<0.001), self-reported health status (p<0.001) and age (p=0.01). CONCLUSIONS: Meeting PA guidelines of 150 minutes of moderate to vigorous PA per week was associated with reduced doctor visits and associated cost. Furthermore, these resutls support previous findings where employees with lower BMI, better self-reported health status and willingness to change were more likely to meet the PA guidelines. These results provide some insight into the economic benefits that can be obtained by being physically active.
Chemical reactions on solid surfaces: Atomistic observations by scanning tunneling microscopy (1997)

A scanning tunneling microscope has been developed which allows manipulation and control of the surface as well as scanning tunneling microscopy without transfer of the crystal off the manipulator to the microscope. The microscope is of the ‘Johnnie Walker’ type and is lowered onto the crystal, which is itself housed in a versatile transfer carriage. In this fashion surfaces can be ion bombarded, chemically treated, etc. and examined by the microscope at temperatures ranging from 120–400 K with atomic resolution without change in surface temperature. With this microscope we have studied the reaction of carbon monoxide with oxygen on Cu(110). At an ambient pressure of 10−4 Torr carbon monoxide reacts with the p(2 × 1) islands of oxygen at a measurable rate only at 400 K or above. Reaction is approximately 1000 times faster along the (001) direction of the oxide islands than along the (110) direction. Reaction does not occur internal to the island unless there are defects to initiate the reaction. At 400 K the oxide islands do not maintain an equilibrium shape or distribution when reacting with ambient carbon monoxide, though in the presence of a low pressure of oxygen they appear to do so. At 150 K the p(2 × 1) oxide islands are inert to reaction with carbon monoxide and, additionally, short CuO chains are also unreactive. Reaction between pre-adsorbed carbon monoxide and ambient oxygen is observed, implying that mobile oxygen atoms which have not yet formed surface-bound pseudomolecules, can react with adsorbed carbon monoxide.
On path-level traffic grooming strategies in WDM metro optical networks (2008)

This article provides an overview of some of the optical grooming (aggregation) techniques that have been developed recently with IP as the client layer. We identify four kinds of aggregation strategies: point to point (P2P), point to multipoint (P2MP), multipoint to point (MP2P), and multipoint to multipoint (MP2MP). Using an auxiliary graph-based model, we evaluate the performance of these four strategies for singlehop and multihop scenarios that aggregate at the path level. In the case of partial mesh networks with dynamic traffic, we observe the following: MP2MP outperforms other architectures by multiple orders of magnitude in single-hop scenarios; P2P performs best in multihop transceiver-constrained scenarios; and P2MP performs the best in multihop wavelength-constrained scenarios.
Krill Herd Algorithm for Signal Optimization of Cooperative Control With Traffic Supply and Demand (2019)

As a novel signal control method, signal Cooperative Control with traffic Supply and Demand (CCSD) is superior to the traditional control methods and could satisfy the control requirements under all traffic conditions. However, the optimization solution of CCSD cannot meet the real-time control requirement for its exhaustive search. To overcome the problem, in this paper, the optimization problem of CCSD is reconstructed by the time-varying traffic supply and demand, and the problem is reduced as a problem of space search. Then, the krill herd (KH) algorithm is introduced and employed to realize the fast solution of CCSD (named KH-CCSD). During the process of optimization, the search space representation and fitness function for the KH algorithm are constructed to satisfy the solution of CCSD. The optimal signal timing plan is obtained by an iterated search of krill swarm in a multi-dimensional time-varying space cooperatively constrained by traffic supplies and demands. The convergence and effectiveness of KH-CCSD are validated by comparing experiments, in which the convergence of KH-CCSD is tested by different initializations and KH-CCSD is compared with the Webster method and capacity-aware back-pressure (CABP) control under unsaturated, saturated, and oversaturated conditions. The experiments results show that KH-CCSD performs a fast convergence and KH-CCSD is superior to the Webster method and CABP. As a result, KH-CCSD could satisfy the application of CCSD under all traffic conditions.
Rapid Inactivation of Glyphosate in the Soil (1975)

In greenhouse studies, soil applications of 14 C-methyl-labeled glyphosate [N-(phosphonomethyl)glycine] were not readily absorbed by corn ( Zea mays L. ‘Michigan 400’) and soybean [ Glycine max (L.) Merr. ‘Hark’]. However, glyphosate available to plants in sand culture was absorbed. Wheat ( Triticum aestivum L. ‘Avon’) a sensitive bioassay plant, was used to detect the herbicide. Clay loam and muck soil rapidly inactivated 56 kg/ha of glyphosate. Autoclaving of the soil did not prevent the inactivation of glyphosate. In a sandy clay loam soil, application of 56 kg/ha of glyphosate decreased plant growth with increasing pH. Additions of 98 or 196 kg/ha of phosphate to the soil surface decreased glyphosate inactivation in the soil. It is postulated that initial inactivation of glyphosate in soil is by reversible adsorption to clay and organic matter through the phosphonic acid moiety.

[Successful treatment with combination chemotherapy of BHAC-AMP in a case of acute myelofibrosis developed from myelodysplastic syndrome with multiple chromosomal aberrations]. (1993)

A 62 year old male patient was previously admitted to another hospital in February 1989 because of palpitation. Peripheral blood examination revealed pancytopenia. Although the number of nucleated cells in the bone marrow aspirate was in the normal range. It contained 2.2% of blastic cells and dysplastic cells. He was diagnosed to be myelodysplastic syndrome with refractory anemia. He subsequently received repeated blood transfusions and other symptomatic treatments as an outpatient until 1990. When he was admitted to our hospital because of severe pancytopenia. The numbers of WBC, RBC, and platelets were 2,000/microliters, 134 x 10(4)/microliters, 2.9 x 10(4)/microliters respectively. Bone marrow aspiration resulted in dry tap, and biopsy at the iliac bone showed remarkable fibrosis with marked decrease of normal hematopoietic cells. Chromosome analysis revealed multiple aberrations such as 47XY, +8, 13q-, 14p+, 48XY, +8, +9, 13q+. The patient was treated with BHAC-AMP combination chemotherapy. After 3 cycles of the therapy, pancytopenia was improved and chromosomal aberration disappeared. This case was considered to be an acute myelofibrosis developed from myelodysplastic syndrome and worth to reporting with a review of literature, because drastic combination chemotherapy was extremely effective.
Expression of minichromosome maintenance-2 in human malignant fibrous histiocytomas: Correlations with Ki-67 and P53 expression, and apoptosis (2002)

This study examined the clinicopathological significance of minichromosome maintenance-2 (MCM2) expression in 38 human malignant fibrous histiocytomas (MFHs) and 36 benign fibrohistiocytic tumors (BFHTs) immunohistochemically, and in 9 human sarcoma or carcinoma cell lines, as well as 7 surgical specimens by Western blotting. MCM2 was detected in all the cell lines and surgical specimens as a single band at 120 kDa, while P53 expression was variable. Nuclear expression of MCM2 was noted in tumor but not mitotic cells of all the MFHs and 26 (72.2%) of the BFHTs, the labeling indices (LIs) being 62.0% in the 28 ordinary types, 38.5% in the 10 myxoid types, and 11.2% in the BFHTs with significant difference. Moreover, the LI was significantly higher for MCM2 than that for Ki-67 in the MFHs of both types (p<0.05). No correlation was noted between the MCM2-LI and P53 expression or apoptotic indices, which were significantly higher in the MFHs than BFHTs (p<0.01). These results indicate that MCM2 would correlate with cell proliferation rather than apoptosis in MFHs, and the expression is ubiquitous in proliferating cells, regardless of the expression of P53. Thus, MCM2 might be a reliable marker of proliferating cells in human MFH.
Investigation of vacuum ultraviolet generation in a resonant four-wave mixing scheme in krypton with electro-magnetically induced transparency (1998)

Abstract We report experiments investigating a resonant sum-difference frequency mixing scheme in krypton producing coherent radiation at 123.6nm (i.e. in the vacuum ultraviolet (VUV)). Owing to the resonant nature of this scheme, electromagnetically induced transparency (EIT) plays a crucial role in the generation of this coherent radiation, resulting in a greatly enhanced conversion efficiency. This is the first time a resonant sum-difference mixing scheme involving EIT, that generates VUV radiation, has been investigated experimentally. Our results are in broad agreement with theoretical predictions. Measurements are presented of the dependence of VUV generation on laser detuning (in the range ± cm−1) and laser powers. In particular the dependence on the coupling field strength has been studied in the range of coupling field Rabi frequencies Ωc = 0.05−3 cm−1. We estimate an enhancement in the conversion efficiency, compared with the non-resonant case, of greater than 102.
Efficient handoff for mass transit connectivity using IEEE 802.11 (2015)

In the recent years, WiFi standard has been used to develop different kind of wireless networks due to its flexibility and the availability of cheap off the shelf hardware. Even if the standard itself lacks mobility support, it has been used in networks with mobile nodes. When mobility is involved, a fast handoff is of paramount importance, especially with multimedia applications. The current IEEE 802.11 standard does not provide any specification about how the handoff should take place. In this paper we propose a handoff scheme optimized for networks providing wireless connection to mass transit vehicles. The structure of the procedure is redesigned to minimize delay as well as assure reliability. A reliable handoff triggering mechanism is also designed exploiting the results obtained from a set of preliminary outdoor experiments. The proposed scheme was implemented and deployed in an experimental testbed, and several indoor tests were run in order to demonstrate its reliability and efficiency.
An Improved Monocular Forest Fire Point Positioning Method on the Grayscale Bit Plane (2016)

For the forest, the fire is an extremely serious damage. In the forest fire point positioning research, it was found that the monocular vision system combination of digital elevation model(DEM) is a better way to locate fire position. However, this method has insufficient. This paper presents an improved monocular forest fire point positioning method on the grayscale bit plane. This way can make up for the lack of original method. Simulation experiment shows that improved method can achieve the fire point when the presence of obstructions.
