Multi-Carrier CDMA for Network Assisted Device-to-Device Communications for an Integrated OFDMA Cellular System (2016)

Device-to-Device communication (D2D) has been a hot research topic in recent years, especially concerning the integration of D2D and conventional cellular networks. In general, the integration improves the efficiency and flexibility of the overall system. Furthermore, D2D can provide partial solutions for some inherent problems of cellular systems, such as cell edge related problems. Currently, most of the D2D integration studies assume that D2D UEs and cellular UEs use identical multiple access (MA) technology for the convenience of integration and backward compatibility. In this paper, besides the conventional OFDMA based D2D, we investigate the use of multicarrier code division multiple access (MC-CDMA) as the MA scheme for D2D UEs. The idea is to use processing gains obtained by spreading against critical interference, especially from cellular UEs. The study is emphasized on interference related issues, including interference analysis of the integrated system, and overall performance enhancement, mainly for D2D UEs, by utilizing frequency domain spreading. Network simulations show the gain against critical interference from cellular UEs. Meanwhile, it is shown that intra-cell cross mode interference control/elimination is the key scheme to guarantee performance of the integrated system. Furthermore, we discuss the potential benefits and procedures of MC-CDMA D2D based cluster integration.
Prestack 9‐C joint inversion for stratigraphic prediction in the Williston Basin (2007)

We have successfully applied the multicomponent prestack elastic waveform inversion methodology proposed by Agullo et al (2004) to 9‐C 3D data from North Dakota. The objective of the survey was to image grainstone shoals which form stratigraphic traps for oil using the P and shear modes. The shoals are a difficult exploration target as they are characterized by a subtle, nonunique P‐wave seismic response. Prestack joint elastic inversion of the P and SH modes delineates both the shoal itself and the updip seal facies that act as the trap in this part of the play. Elastic attributes were particularly successful at characterizing the dolomite fraction at the reservoir, which allowed mapping of trap geometries.
Concept-oriented access to longitudinal multimedia medical records: A case study in brain tumor patient management (2009)

Abstract. The current clinical practice requires physicians to gather, interpret and correlate information from multiple independent multimedia data sources to manage patients. Due to poor structuring and organization, it is too timeconsuming to access the information snippets embedded in the various pieces of data in the longitudinal patient records. This becomes more of a problem when correlating the temporal progression of various factors obtained from patients clinical, laboratory, imaging and genomics studies. Making such correlations is an essential component of the prognosis and treatment planning tasks in patient care. In addition, the similarities in the disease progression pattern among different patients and their relationships to outcomes remain hidden from the clinicians in the piecemeal use of the data. We believe that there is a gap between the decision-enabling information and insight required for efficient patient management and the heterogeneous data comprising the patient records that can be bridged with advanced multimodal content analytics, semantic information organization, summarization, and visualization tools. In this paper we present a case study in organizing, accessing, and visualizing information obtained through structuring the multimedia and multimodal data for brain tumor patient management and how such information map to the needs of the clinicians. We report our early work on the analytics, user interface and the preliminary evaluation results which indicate that the presented approach caters well to the clinician needs for the task of brain tumor patient management. 1
Scatterer localization using a left-handed medium (2009)

This paper explores the possibility of using the focusing property of left-handed materials to estimate the location of a visually obscured target. The field scattered by the target and measured on a surface can be considered as incident upon a left-handed half-space and should converge to a point resembling the mirror image of the scatterer's location. The results are obtained using the method of auxiliary sources as adapted to double-negative media. Two-dimensional scattering is considered, either from a single object or from several targets, using pointlike and Gaussian sources of illumination. The method gives reasonable results when the sizes of the scatterers are comparable to the wavelength.
In Situ Control of Interface Coatings on Fibers Using CVD (1997)

Abstract Most ceramic matrix composites (CMC’s) require a fiber interface coating in order to exhibit the desirable properties that make them potentially useful high temperature structural materials.6,9 Although interface coatings are widely recognized as a key to these properties, fiber coating technology has received relatively little attention, hindering successful application of CMC’s. Additionally, in today’s search for new oxidation resistant interfaces, the inability to deposit coatings of controlled chemistry, thickness, and morphology is a significant problem.5
Synthesis of diffractive optical bar codes (1992)

A new type of diffractive optical bar code (DOBC) is proposed. Rather than scanning directly, the DOBC is coherently illuminated, and the first diffraction order is sensed. The spacing between the bars is chosen so that the thresholded diffraction pattern yields a specified binary code. Two approaches are investigated for synthesis of the DOBC: phase shaping and a gradient-based, nonlinear, constrained optimization technique. The two design methods are compared based on numerical results, and the validity of the overall design approach is verified by optically sensing the diffraction patterns for a number of fabricated DOBC's.
Surgical Needs of Internally Displaced Persons in Kerenik, West Darfur, Sudan (2020)

We identified and characterized a high burden of surgical and potentially surgical disease in an IDP population in West Darfur. Our study is unique in its direct assessment of a traumatized, mobile, vulnerable population. Health officials and agencies charged with the care of IDP and refugee populations should be aware of the high prevalence of surgical and potentially surgical conditions in these communities. This study adds to the growing body of evidence that investment in surgical resources may address a significant portion of the overall burden of disease in marginalized populations.
Integrated skin sensitization assessment based on OECD methods (II): Hazard and potency by combining kinetic peptide reactivity and the “2 out of 3” Defined Approach (2022)

Depending on regulatory requirements, the skin sensitization risk for new chemicals with potential consumer skin contact must be assessed by experimental testing by (i) binary hazard assessment to identify sensitizers, (ii) subclassification of sensitizers according to the Global Harmonized System (GHS), and (iii) derivation of a point of departure (PoD) for risk assessment. The Organisation for Economic Co-operation and Development (OECD) recently published a test guideline incorporating the “2 out of 3” defined approach (2o3 DA) for skin sensitization hazard assessment and added the kinetic direct peptide reactivity assay (kDPRA) as a stand-alone test guideline method for GHS subclassification. The 2o3 DA requires that at least two in vitro tests are conducted. The cell-based tests and the kDPRA generate, next to a binary outcome with a fixed threshold, continuous concentration-response data, which can be used in quantitative regression models to derive a PoD. The sequence of testing for the 2o3 DA is flexible. Here we compare different testing sequences and how they can be combined with kDPRA data to provide a PoD in parallel to hazard identification (hazard ID) and GHS subclassification. A set of 188 chemicals with available in vitro data was evaluated for the final PoD using these dif-ferent testing sequences. The results indicate that testing can start with DPRA / kDPRA and either of the cell-based assays, and that testing can stop after two congruent tests without major impact on the final PoD for chemicals within the applica-bility domain of the kDPRA.
Coupling into slow-light in photonic-crystal waveguides (2008)

Coupling into the slow-light regime of photonic crystal waveguides is investigated for various taper lengths and terminations by utilizing an integrated Mach-Zehnder interferometer. Experimental results for coupling efficiency as a function of group-index are presented.
Downregulation of c-FLIP Sensitizes DU145 Prostate Cancer Cells to Fas-Mediated Apoptosis (2002)

Although DU145 prostate cancer cells are resistant to exogenously applied Fas agonist CH-11 (anti-Fas monoclonal antibody), Fas-resistance can be overcome using a FasL expressing adenovirus (AdGFPFasL(TET)) [Hyer et al., Molecular Therapy, 2000; 2:348-58 (ref.12)]. The purpose of this study was to try to understand why DU145 cells are resistant to CH-11 and determine the signaling pathway utilized by AdGFPFasL(TET) to induce apoptosis in these Fas-resistant cells. Using immunoblot analysis, we show that AdGFPFasL(TET) is capable of initiating the classic Fas-mediated apoptotic pathway in DU145 cells, which includes activation of caspases-8, -3, -7, and -9, BID cleavage, cytochrome c release from mitochondria, and PARP cleavage. In contrast, CH-11 binds to Fas, but is unable to transmit the death signal beyond the plasma membrane suggesting a block at the DISC (death inducing signaling complex). The anti-apoptotic protein c-FLIP (cellular Flice-like inhibitory protein), which has been shown to inhibit Fas-mediated apoptosis at the DISC, was down-regulated following AdGFPFasL(TET) treatment prompting us to investigate its role in inhibiting CH-11-induced cell death. Using c-FLIP anti-sense oligonucleotides to down-regulate c-FLIP we sensitized DU145 cells to CH-11-induced apoptosis. These data suggest that c-FLIP may play a critical role in regulating Fas-mediated apoptosis in prostate cancer cells and that modulation of c-FLIP may enhance Fas signaling based therapies.
On the correlation of observed discharges and geomorphologic characteristics in Central Italy (2009)

In small and middle catchments or intermittent rivers, characterised by low or no flow for long time of the year, it&#13;\nis possible to have water management and quality problems and sudden floods.&#13;\nThe aim of this work is to show the influence of precipitation volume, type of precipitation and morphologic&#13;\ncharacteristics on the river flow. Furthermore, the correlation between these parameters and the flow discharge&#13;\nindicators, as Q100, Q95, Q50, Q5 and Q0 (i.e. discharges that are exceeded 100% 95%, 50%, 5% and 0% of the&#13;\ntimes) is estimated.&#13;\nUsing the geomorphologic characteristics of the catchment (catchment area, concentration time, Curve Number)&#13;\nand the climatic characteristics (mean annual precipitation calculated over the catchment and time variability of&#13;\nrainfall events) different regions are pointed out in the target area, in particular showing the role of mountains.&#13;\nFinally a multiple regression relationship is found between this flow discharge indicators and morpho-climatic&#13;\ncharacteristics and statistical tests are used to assess the model, calibrated for all basins of Lazio and Umbria&#13;\nRegions.

Involvement of Vacuolar Protein Sorting Pathway in Ebola Virus Release Independent of TSG101 Interaction (2007)

Budding of Ebola virus (EBOV) particles from the plasma membrane of infected cells requires viral and host proteins. EBOV virus matrix protein VP40 recruits TSG101, an ESCRT-1 (host cell endosomal sorting complex required for transport-1) complex protein in the vacuolar protein sorting (vps) pathway, to the plasma membrane during budding. Involvement of other vps proteins in EBOV budding has not been established. Therefore, we used VP40 deletion analysis, virus-like particle-release assays, and confocal microscopy to investigate the potential role of ESCRT-1 proteins VPS4, VPS28, and VPS37B in EBOV budding. We found that VP40 could redirect each protein from endosomes to the cell surface independently of TSG101 interaction. A lack of VPS4 adenosine triphosphatase activity reduced budding by up to 80%. Inhibition of VPS4 gene expression by use of phosphorodiamidite morpholino antisense oligonucleotides protected mice from lethal EBOV infection. These data show that EBOV can use vps proteins independently of TSG101 for budding and reveal VPS4 as a potential target for filovirus therapeutics.
Evaluation of Dietary Aspergillus Meal on Intestinal Morphometry in Turkey Poults (2010)

A trial was conducted to evaluate the influence of dietary Aspergillus Meal (AM) prebiotic on intestinal development, morphology in turkey poults. Day-old Nicholas poults (n = 100) were randomly assigned to two groups. Poults in each group were divided and placed in floor pens with 50 poults each. One group served as a control and received a ration containing no added AM prebiotic. Poults in the treatment group were provided a ration supplemented with 0.2% AM prebiotic. Each dietary regimen and water were provided ad libitum to 30 days of age. Poults were humanely killed by CO2 inhalation and specimens of duodenum and distal ileum were collected at 10, 20 and 30 days. Histology sections were cut (5 μm) and stained with haematoxylin and eosin and combinations of either of periodic acid-Schiff with alcian blue, or high iron diamine with alcian blue stains to evaluate 20 intact villi on each section. The morphometric variables analyzed included villi height, villi surface area and crypt depth. In addition, goblet cells, classified as neutral, acidic or sulpho mucin cells, respectively, were quantitative for each treatment group. At all times of evaluation, AM prebiotic significantly increased the number of acid mucin cells in the duodenum, neutral mucin cells in the ileum and sulpho mucin cells in the duodenum and ileum. Villi height and villi surface area of both duodenum and ileum were significantly increased at days 10 and 30 compared to control. The present study suggest that AM prebiotic has an impact on the mucosal architecture and goblet cells proliferation in the duodenum and ileum of neonate poults.
Why should we need the gut microbiota to respond to cancer therapies? (2014)

Cyclophosphamide, one of the most efficient tumoricidal, antiangiogenic, and immunostimulatory drugs employed to date mediates part of its effects through intestinal bacteria, against which the host becomes immunized during treatment. Our recent work suggests that anti-commensal effector pT<sub>H</sub>17 and memory T<sub>H</sub>1 CD4<sup>+</sup> T-cell responses are indispensable for optimal anticancer effects as mediated by cyclophosphamide.
A fully integrated 60GHz CMOS transceiver chipset based on WiGig/IEEE802.11ad with built-in self calibration for mobile applications (2013)

A 60GHz short-range wireless system offers new opportunities for achieving wireless high-definition video links and multi-Gb/s wireless data transfer. Recent works have realized a 60GHz transceiver by means of a cost-effective CMOS process [1-3], but using a 60GHz system in mobile terminals poses the difficult challenge of achieving low power consumption as well as small form factor. The publication [3] achieves a power consumption of less than 756mW, but uses a simple MAC protocol incompatible with global standards and also suffers from a limited distance of less than 4cm. This paper presents a fully integrated transceiver chipset based on WiGig/IEEE802.11ad standards targeting mobile usage. The chipset is developed for a single-carrier (SC) modulation, which is suitable for reduced power consumption as compared to using OFDM modulation. However, the SC modulation is sensitive to in-band amplitude variation, mainly made worse by the gain variation of analog circuits and multipath delay spread. In order to compensate for those gain variations, the proposed chipset employs built-in TX in-band calibration and an RX frequency domain equalizer (FDE). The proposed techniques can relax the requirement for high speed analog circuits, leading to less power consumption while minimizing the increase of hardware size.
Exact integer hybrid subdivision and forward differencing of cubics (1994)

Forward differencing is widely used to generate rapidly large numbers of points at equally space parameter values along a curve. A failing of forward differencing is the tendency to generate many extraneous points for curves with highly nonuniform parameterizations. A key result is presented and proven, namely, that a few levels of subdivision, prior to initialization for forward differencing, can improve substantially the quality of the step size estimate, resulting in very few extra points. The initial subdivisions can be done without loss of the exact integer precision available in forward differencing. For small numbers of points—a common occurrence in fonts—exact subdivision is even faster than exact forward differencing. When exact subdivision is used in conjunction with a previously presented exact forward-differencing algorithm, arbitrary cubic curves may be rendered with 32-bit arithmetic and guaranteed single-pixel accuracy, in a grid with an address space as large as 0…7281, with no two generated points greater than one pixel apart. This is more steps than previously possible. Previous discussions of rendering using subdivision have concentrated not on distance but on straightness estimates, whereby subdivision can be stopped once a subcurve can be drawn safely using its polygonal approximation. In this article, bounds are also derived on the size of the control polygon after multiple levels of subdivision: these are used to determine bounds on the number of steps required for differencing. It is shown that any curve whose rasterization fits in a space of ω pixels requires no more than 9ω steps.
Multi-phasic life-threatening anaphylaxis refractory to epinephrine managed by extracorporeal membrane oxygenation (ECMO): A case report (2022)

We present a case of a 52-year-old patient suffering from multi-phasic life-threatening anaphylaxis refractory to epinephrine treatment. Extracorporeal membrane oxygenation (ECMO) therapy was initiated as the <i>ultima ratio</i> to stabilize the patient hemodynamically during episodic severe bronchospasm. ECMO treatment was successfully weaned after 4 days. Mastocytosis was diagnosed as the underlying condition. Although epinephrine is recommended as a first-line treatment for anaphylaxis, this impressive case provides clear evidence of its limited therapeutic success and emphasizes the need for causal therapies.

Definitions of Terms Relating to Mass Spectrometry (IUPAC Recommendations 2013) (2013)

This study was conceived to evaluate the global scientific output of secondary organic aerosol research over the past 20 years and to assess the characteristics of the research patterns, tendencies, and methods in the papers.Data were based on the online version of Science Citation Index Expanded from 1992 to 2011.Publications referring to secondary organic aerosols were assessed by distribution of the number of publications and times cited, source categories, source journals, author keywords, KeyWords Plus, and the most cited publications in these years.By synthetic analysis of author keywords, KeyWords Plus, titles, and abstracts, it was concluded that modeling is currently-and will at least over the next decade continue to be-the predominant research method to validate state-of-the-art knowledge of secondary organic aerosols, and that the foci of such research will be the key precursors terpenes and isoprene, the mechanisms of oxidation and gas-phase reactions, and emission inventories.
Novel power transistor design for a process independent high voltage option in standard CMOS (2006)

High voltage transistors can be implemented in standard CMOS by interleaving drain extensions with STI using the fine STI/active patterns. This approach facilitates integration of high voltage transistors in modern processes without increasing processing complexity. This paper presents an in depth analysis of simulation and experimental data in a commercial 90 nm CMOS process. It is shown that the STI layout in the channel and the drain extension can be optimised separately which results in a better current drive of the resulting voltage transistors. The scope and limits of this device concept are discussed.
