Analysis of the mouse embryonic stem cell regulatory networks obtained by ChIP-chip and ChIP-PET (2008)

This study suggests that each dataset is a partial representation of the overall ES cell regulatory circuitry, and through integrating binding data obtained by ChIP-chip and ChIP-PET, the methods presented here provide a useful means for integrating datasets obtained by different techniques in the future.
Control Of Translation From The mRNA 3′ End (2007)

The eukaryotic mRNA 3′ polyA tail acts synergistically with the 5' cap structure to enhance translation. This mechanism is effected by a bridging complex, composed of the poly (A) binding protein (PABP), eIF4G, and the cap‐binding protein, eIF4E, which brings about mRNA circularization. The bridging between the mRNA 5' and 3' ends is regulated by several different mechanisms. We have discovered proteins that bind to PABP, termed Paips ( PA BP‐ i nteracting p roteins), which control translation initiation. Paip1 stimulates translation through its simultaneous interactions with PABP, eIF4A and eIF3, while Paip2 inhibits translation by dislodging PABP from the polyA tail and by competing with eIF4G for binding to PABP. The structural basis for the function of the Paips will be discussed.
Posttransplantation Lymphoprolif erative Disorders in Bone Marrow Transplant Recipients Are Aggressive Diseases With a High Incidence of Adverse Histologic and Immunobiologic Features (1997)

Posttransplantation lymphoproliferative disorders (PT-LPDs) occurring in T-cell depleted (TCD) allogeneic bone marrow transplant recipients seem to be different from those that arise in solid organ recipients in their early development, the high incidence of extensive dissemination at presentation, and their aggressive course and high fatality rate. We report a series of 10 patients with PT-LPDs after TCD allogeneic bone marrow transplant. We studied the correlation between the morphology of the lesions; their clonality based on immunoglobulin (Ig) heavy chain gene rearrangement analysis and immunohistochemistry; their proliferative activity as measured by immunoperoxidase staining for the proliferating cell nuclear antigen (PCNA) and the presence of p53 gene product overexpression. Histologically, our cases corresponded to the two morphologic categories of polymorphic B-cell lymphoma (PBCL, seven cases) and malignant lymphoma immunoblastic (ML-IB, three cases). Ig light-chain staining showed monoclonality in a minority of the cases, whereas Ig gene rearrangement analysis by polymerase chain reaction revealed B-cell clonality in three of seven cases of PBCL and in all three cases of ML-IB. The Epstein-Barr virus (EBV) genome, the expression of EBV latent membrane protein or both were found in all 10 specimens. High proliferative activity (PCNA > or = 66%) was found in all cases, with a mean PCNA value of 56% in PBCL and 84% in ML-IB. Five specimens were p53+ (two of seven PBCL and three of three ML-IB). Two of four PBCL cases resolved with the administration of donor leukocytes. All of the remaining patients died of the PT-LPD within a short time from admission. Our results show that the PT-LPDs after TCD bone marrow transplantation are characterized by a high frequency of high-grade histologic subtypes, frequent monoclonality, high proliferative activity, frequent overexpression of p53 gene product, and poor prognosis. These characteristics observed in only a minority of cases of PT-LPDs occurring after solid organ transplantation may account for the less aggressive clinical behavior observed in those diseases.
The pearson IV distribution and its application to ion implanted depth profiles (1980)

Abstract The Pearson IV distribution system is analyzed to determine the regions of validity for the values of the moments that produce convex, concave, more pointed than Gaussian, and more flat-topped than Gaussian distributions; the limits beyond which no significant change in distribution is produced; and excluded regions. These regions are illustrated in a figure that can be used to facilitate the determination of the Pearson IV moments for experimental ion implanted depth distributions. Examples are given of Pearson IV distributions to illustrate the effects of the ranges of skewness, kurtosis, and standard deviation, for both more pointed and more flat-topped than Gaussian distributions. A procedure is described for matching experimental ion implanted depth distributions to computer plotted Pearson IV modified Gaussian distributions. A few experimental curves are given to illustrate the different types of Pearson IV curves, and accuracies of moments are discussed.
Femtosecond-laser-driven photoelectron-gun for time-resolved cathodoluminescence measurement of GaN (2012)

A rear-excitation femtosecond-laser-driven photoelectron gun (PE-gun) is developed for measuring time-resolved cathodoluminescence (TRCL) spectrum of wide bandgap materials and structures such as semiconductors and phosphors. The maximum quantum efficiency of a 20-nm-thick Au photocathode excited using a frequency-tripled Al(2)O(3):Ti laser under a rear-excitation configuration is 3.6×10(-6), which is a reasonable value for a PE-gun. When the distance between the front edge of the PE-gun and the observation point is 10 mm, the narrowest electron-beam (e-beam) diameter is 19 μm, which corresponds to one tenth of the laser-beam diameter and is comparable to the initial e-beam diameter of a typical W hair-pin filament of thermionic electron-gun. From the results of TRCL measurements on the freestanding GaN grown by the ammonothermal method and a GaN homoepitaxial film grown by metalorganic vapor phase epitaxy, overall response time for the present TRCL system is estimated to be 8 ps. The value is the same as that of time-resolved photoluminescence measurement using the same excitation laser pulses, meaning that the time-resolution is simply limited by the streak-camera, not by the PE-gun performance. The result of numerical simulation on the temporal e-beam broadening caused by the space-charge-effect suggests that the present PE-gun can be used as a pulsed e-beam source for spatio-time-resolved cathodoluminescence, when equipped in a scanning electron microscope.
Recent developments in phosphorus based flame retardant coatings for textiles: Synthesis, applications and performance (2022)

Textiles contain a high content of carbon and hydrogen in their structure which provides the fuel for combustion and therefore are hazardous in case of a fire accident. A suitable flame retardant (FR) treatment for textiles is a common practice for their fire safe applications. Although plenty of well-known effective FR systems are already known for textile applications, there is a need to develop new effective environmental friendly FR agents and their treatments to meet existing environmental and technical requirements. Thus, development of phosphorus based new flame retardant compounds for application in textile treatments has been a major focus in academia and industry. This review summarizes the recent reports (last 5 years) on the preparation of phosphorus based FR compounds and their application on various natural and synthetic textiles via coating methodology. The reported literature typically addresses improvement of FR efficiency by synergistic interaction of phosphorus with other environmentally acceptable flame retardant elements such as nitrogen, silicon, sulfur and boron and is thus addressed in detail in this review.
Bus Arrival Time Prediction: A Spatial Kalman Filter Approach (2019)

Public transport buses have uncertainties associated with its arrival/travel times, due to several factors such as signals, dwell times at bus stops, seasonal variations, fluctuating travel demands, and so on. In the developing world, these uncertainties are further magnified by the presence of excess vehicles, diverse modes of transport, and acute lack of lane discipline. Hence, the problem of bus arrival time prediction continues to be a challenging one especially in developing countries. This paper proposes a new methodology for bus arrival time prediction in real time. Unlike existing approaches, the proposed method explicitly learns the spatial (and temporal) correlations/patterns of traffic in a novel fashion. Specifically, it first detects the unknown order of spatial dependence and then learns linear, non-stationary spatial correlations for this detected order. It learns temporal correlations between successive trips as a function of their time difference. To make the optimal prediction feasible, the learnt predictive model is rewritten in a suitable linear state-space form, and then, an appropriate Kalman filter (KF) is applied. The performance was evaluated with real field data and compared with existing methods.
Detection of audible resonances (2007)

Abstract: The paper discusses the problem of the detection of audible resonances. The basic psychoacoustic researches have shown that the threshold of resonance detection can be classified by resonance level and Q-factor. In this work a third criteria is introduced. It is the energy of the resonance. By analyzing the influence of resonances on the frequency response and group delay, it is shown that it is almost impossible to detect resonances that are near the threshold of audibility. Finally, three common techniques for resonance detection are compared: the cumulative spectral decay, the shaped sine burst decay and the transfer function pole–zero identification. In the conclusion suggestions for the use of the particular method are given.
In situ resistance measurements during physical vapor deposition of ultrathin metal films on Si(111) at room temperature (2017)

The resistance of ultrathin metal films (Ag, Au, Cr, Ir, Pt, and Ti) on hydrofluoric acid-treated Si(111) surfaces is investigated during room temperature evaporation at very low deposition rates (0.003–0.006 nm/s). High-resolution in situ measurements are performed using the four-point probe technique. The authors find that, in addition to the type of metal, the resistance versus metal thickness characteristics heavily depend on the doping of the Si substrate. Furthermore, for most metals on p-type Si, the resistance initially increases as a function of deposition time. The authors explain this by a conductive path at the surface due to H-terminated Si bonds which are destroyed during deposition.
Cu(II) Oxide Amorphous Nanoclusters Grafted Ti3+ Self-Doped TiO2: An Efficient Visible Light Photocatalyst (2011)

Ti3+ self-doped TiO2 was prepared by a facile one-step thermal oxidation of Ti2O3 and TiO2 mixture in air. Electron spin resonance (ESR) spectra confirmed the presence of Ti3+ in this sample. Ti3+ states caused a visible light absorption, which is originated from the isolated band in its forbidden gap. Although the photocatalytic activity of this Ti3+ self-doped TiO2 was negligible even under the UV light, its UV and visible light activities were drastically increased by the grafting of Cu(II) oxide amorphous clusters with a size of around 2 nm as a co-catalyst. Consequently, the photocatalytic decomposition of gaseous 2-propanol (IPA) into CO2 with a maximum generation rate of 0.20 μmol/h and a quantum efficiency of 10.8% is achieved, under the visible light irradiation. Its efficient visible light activity is highly stable in air and can be repeatedly used for a long term.
Towards Defeating the Crossfire Attack using SDN (2014)

In this work, we propose online traffic engineering as a novel approach to detect and mitigate an emerging class of stealthy Denial of Service (DoS) link-flooding attacks. Our approach exploits the Software Defined Networking (SDN) paradigm, which renders the management of network traffic more flexible through centralised flow-level control and monitoring. We implement a full prototype of our solution on an emulated SDN environment using OpenFlow to interface with the network devices. We further discuss useful insights gained from our preliminary experiments as well as a number of open research questions which constitute work in progress.
Optogenetic silencing of primary afferents reduces evoked and ongoing bladder pain (2017)

Patients with interstitial cystitis/bladder pain syndrome (IC/BPS) suffer from chronic pain that severely affects quality of life. Although the underlying pathophysiology is not well understood, inhibition of bladder sensory afferents temporarily relieves pain. Here, we explored the possibility that optogenetic inhibition of bladder sensory afferents could be used to modulate bladder pain. Specifically, we chose to study the role of Na v 1.8 + sensory afferents before and after induction of a mouse model of bladder pain. The light-activated inhibitory proton pump Archaerhodopsin (Arch) was expressed under control of the Na v 1.8 + promoter to selectively silence these neurons. Optically silencing Na v 1.8 + afferents significantly blunted the evoked visceromotor response to bladder distension and led to small but significant changes in bladder function. To study of the role of these fibers in freely behaving mice, we developed a fully implantable, flexible, wirelessly powered optoelectronic system for the long-term manipulation of bladder afferent expressed opsins. We found that optogenetic inhibition of Na v 1.8 + fibers reduced both ongoing pain and evoked cutaneous hypersensitivity in the context of cystitis, but had no effect in uninjured, naïve mice. These results suggest that selective optogenetic silencing of bladder afferents may represent a potential future therapeutic strategy for the treatment of bladder pain.

Bessel beam launchers at millimeter waves using higher-order leaky-wave modes (2014)

Near-field shaping is a topic of increasing interest due to a great number of diverse applications, such as medical imaging, diagnostics, power wireless transfer, near-field communications. In this context, focusing electromagnetic energy in certain regions of space is of paramount importance, and it can be achieved through the excitation of Bessel beams: their transverse dependence is of the kind of a nth order Bessel function Jn(·) and is invariant along the propagation direction within the so-called nondiffractive region.

The Immunological Enhancement Activity of Propolis Flavonoids Liposome In Vitro and In Vivo (2014)

The aim of this study was to investigate and assess the effects of propolis flavonoids liposome imposed on the immune system by comparing it to propolis flavonoids and blank liposome. In vitro, the effects of the above drugs on macrophages were assessed by measuring the phagocytic function and cytokine production. In vivo, the immunological adjuvant activity of propolis flavonoids liposome was compared with those of propolis flavonoids and blank liposome. The results showed that in vitro propolis flavonoids liposome can significantly enhance the phagocytic function of macrophages and the release of IL-1β, IL-6, and IFN-γ. In addition, subcutaneous administration of propolis flavonoids liposome with ovalbumin to mice could effectively activate the cellular and humoral immune response, including inducing higher level concentrations of IgG, IL-4, and IFN-γ in serum and the proliferation rates of splenic lymphocytes. These findings provided valuable information regarding the immune modulatory function of propolis flavonoids liposome and indicated the possibility of use of propolis flavonoids liposome as a potential adjuvant.

Electrically tunable narrowband optical filter (1975)

A narrowband optical filter of the Sole type is made from a twisted stack of birefringent plates between polarisers. If the plates are replaced by homogeneously aligned liquid-crystal cells whose retardation is controllable, the transmitted wavelength of the filter can be varied over the visible spectrum. The characteristics of a rudimentary device of this type agree with predictions.

Pediatric Pedicle Screw Placement Using Intraoperative Computed Tomography and 3-Dimensional Image-Guided Navigation (2011)

We report 96.4% accuracy in pediatric pedicle screw placement using intraoperative CT and a 3D navigation system. This is similar to other reports and has better accuracy than a recent meta-analysis of nonnavigated screws in children.
Variable Electronic Coupling through Hydrocarbon Spacers Bridging Metal−Carbon Triple Bonds (1998)

The electrochemical behavior of a series of bis-carbyne complexes, Tp‘(CO)2M⋮(CmHn)⋮M(CO)2Tp‘ (Tp‘ = hydridotris(3,5-dimethyl-1-pyrazolyl)borate; M = Mo, W; m = 3, n = 2; m = 4, n = 0, 2, 4), has been studied. These complexes exhibit two oxidation waves between 0 and 0.5 V (vs ferrocene). The difference in E1/2 for the two oxidation waves is a function of the hydrocarbon spacer with the ⋮C−C⋮C−C⋮ spacers (m = 4, n = 0) exhibiting considerably larger ΔE1/2 values than the corresponding ⋮C−CHCH−C⋮ spacers (m = 4, n = 2), which were in turn more strongly coupled than the saturated analogues (m = 4, n = 4). While the trend in electronic coupling was quantitatively as expected for the degree of unsaturation in the bridge, the absolute magnitude of the coupling as indicated by the comproportionation constants (Kc = 100−104) was much smaller than that in isologous dimers where the bridge is connected to the metal centers via single bonds (Kc = 108−1012). A qualitative model based on relevant orbital occupancy as a function of metal oxidation state has been developed to account for the experimental results.
Selenium Nanocomposites Having Polysaccharid Matrices Stimulate Growth of Potato Plants in Vitro Infected with Ring Rot Pathogen (2019)

The influence of nanocomposites (NC) of selenium in matrices of arabinogalactan (Se/AG) and starch (Se/St) on in vitro vegetation of potato plants, peroxidase activity, and reactive oxygen species has been thoroughly studied. It has been shown that these nanocomposites of selenium have antimicrobial effect to the phytopathogenic bacterium Clavibacter michiganensis ssp. sepedonicus (Cms). In the present investigation, it has been shown that Se/AG NC (6.4% of Se) and Se/St NC (12.0% of Se) have no negative impact on the potato plants healthy and Cms infected, while stimulating their growth, number of leaves and weight of the vegetative part. Se/AG NC has shown a positive effect on potato plants by increasing its immune status by increasing the ROS content and increasing the peroxidase activity. With the use of the element analysis technique, it has been shown that scrutinized nanocomposites are not accumulated in potato plants after the bactericidal processing with the nanocomposites. Se/AG NC and Se/St NC as potential agents used for treatment of potato plants against pathogenic bacteria.

Modelling structures of terrain surface using GIS in Loess Plateau (2015)

Terrain is a combination of several scales of structures, with those different structures being sensitive to different landscape process and influenced by DEM (Digital Elevation Model) resolution in different ways. It is important to separate these structures to investigate their characteristics. In this research, the spatial structure of a terrain surface Loess Hilly areas in the Loess Plateau was analyzed using a 10 m resolution DEM. A geostatistical model named Independent Structures Model (ISM) was built and used to model the semi-variance of different terrain structures with different spatial frequencies. Surface of each terrain structure was mapped by kriging. The result showed that: 1). The spatial components for elevation surface could be modelled through the modelling of semi-variance. In the study area, the elevation surface could be modelled to be three components with range of 82.5 m, 655.4 m and 1974.2 m and one trend component. The third component was the most important because the sill value was larger than the other two components. 2). The three components in the model could be shown to be consistent with half width of catchments with minimum catchment area of 0.1 km 2 , 1 km 2 and 10 km 2 . The result of this work are relevant for research into the scaling effect of terrain parameters and the relationship between terrain and soil erosion modelling, hydrology analysis and related fields.
Distinct Epigenomic Features in End-Stage Failing Human Hearts (2011)

Distinct epigenomic patterns exist in important DNA elements of the cardiac genome in human end-stage cardiomyopathy. The epigenome may control the expression of local or distal genes with critical functions in myocardial stress response. If epigenomic patterns track with disease progression, assays for the epigenome may be useful for assessing prognosis in heart failure. Further studies are needed to determine whether and how the epigenome contributes to the development of cardiomyopathy.
Frailty (2014)

Abstract A frailty model is a random effects model for survival data or other time‐to‐event data. Conceptually, frailty models are similar to the normal distribution mixed models, but they are dedicated to the survival data case, where observations may be censored and where updating is natural as the events happen over time. In actuarial science this covers both life/pension for married couples, and repeated events, like car accidents. The frailty is the common random term and is assumed to enter multiplicatively in the hazard function. The gamma distribution is the most commonly used for the frailty, but other distributions may also be useful. Over the last 20 years, both theory and applications have developed so that by now the frailty models have almost become standard models.
