The range increase of adaptive versus phased arrays in mobile radio systems (2002)

We compare the increase in range with multiple-antenna base stations using adaptive array combining to that of phased array combining. With adaptive arrays, the received signals at the antennas are combined to maximize signal-to-interference-plus-noise ratio rather than only form a directed beam. Although more complex to implement, adaptive arrays have the advantage of higher diversity gain and antenna gain that is not limited by the scattering angle of the multipath at the mobile. We use computer simulation to illustrate these advantages for range increase in both narrowband and spread spectrum mobile radio systems. For example, our results show that for a 3/spl deg/ scattering angle (typical in urban areas) the range increase of a phased array with 100 elements can be achieved by an adaptive array with only 10 elements.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Guided Wave Resonance Tuning for Pipe Inspection (2002)

Tremendous interest has surfaced recently on the use of guided waves in pipe inspection in the oil, chemical, and power generating industries. Relatively long lengths of piping can be inspected for corrosion and cracking from a single probe position. This saves a great deal of time and money compared to using more standard point-by-point normal beam inspection procedures. Pipes can be inspected without removing insulation or tar coatings by controlling the guided wave modes and frequencies used to carry out the study. This paper will review the history and state of the art of the guided wave techniques in piping. Benefits and limitations of the various methods will be pointed out along with a vision of future directions in the area of pipe and elbow inspection.
Transcriptomic profile of genes encoding proteins responsible for regulation of cells differentiation and neurogenesis in vivo and in vitro – an oocyte model approach (2020)

Abstract The growth and development of the oocyte is essential for the ovarian follicle. Cumulus cells (CCs) - a population of granulosa cells - exchange metabolites, proteins and oocyte-derived paracrine factors with the oocyte through gap junctions, to contribute to the competency and health of the oocyte. This bi-directional communication of the cumulus-oocyte complex could be better understood through the micro-analysis of a porcine oocyte gene expression before in vitro maturation (IVM) and after. Additionally, the study of the somatic and gamete cells differentiation capability into neuronal lineage would be promising for future stem cell research as granulosa cells are easily accessible waste material from in vitro fertilization (IVF) procedures. Therefore, in this study, the oocytes of 45 pubertal Landrace gilts were isolated and the protein expression of the COCs were analyzed through micro-analysis techniques. Genes belonging to two ontological groups: neuron differentiation and negative regulation of cell differentiation have been identified which have roles in proliferation, migration and differentiation. Twenty identified porcine oocyte genes ( VEGFA , BTG2 , MCOLN3 , EGR2 , TGFBR3 , GJA1 , FST , CTNNA2 , RTN4 , MDGA1 , KIT , RYK , NOTCH2 , RORA , SMAD4 , ITGB1 , SEMA5A , SMARCA1 , WWTR1 and APP ) were found to be down-regulated after the transition of IVM compared to in vitro . These results could be applied as gene markers for the proliferation, migration and differentiation occurring in the bi-directional communication between the oocyte and CCs.

Enzyme replacement therapy with velaglucerase alfa in Gaucher disease: Results from a randomized, double‐blind, multinational, Phase 3 study (2012)

Type 1 Gaucher disease (GD1), resulting from glucocerebrosidase deficiency, leads to splenomegaly, hepatomegaly, anemia, thrombocytopenia, and bone involvement. Current standard treatment is enzyme replacement therapy. Velaglucerase alfa is an enzyme replacement product for GD1, with the same amino acid sequence as naturally occurring human glucocerebrosidase. This multinational, Phase 3 trial evaluated the efficacy and safety of two doses of velaglucerase alfa in 25 treatment-naïve, anemic patients with GD1 (4-62 years of age), randomized to intravenous velaglucerase alfa 60 U/kg (n=12) or 45 U/kg body weight (n=13) every other week for 12 months. The primary endpoint was change from baseline in hemoglobin concentration in the 60 U/kg arm. At 12 months, mean hemoglobin concentrations increased from baseline [60 U/kg: +23.3%; +2.43 g/dL (P<0.001); 45 U/kg: +23.8%; +2.44 g/dL (P<0.001)], as did mean platelet counts [60 U/kg: +65.9%; +50.9 × 10(9) /L (P=0.002); 45 U/kg: +66.4%; +40.9 × 10(9) /L(P=0.01)]. Mean splenic volume decreased from baseline [60 U/kg: -50.4%, from 14.0 to 5.8 multiples of normal (MN) (P=0.003); 45 U/kg: -39.9%, from 14.5 to 9.5 MN (P=0.009)]. No drug-related serious adverse events or withdrawals were observed. One patient developed antibodies. Velaglucerase alfa was generally well tolerated and effective for adults and children with GD1 in this study. All disease-specific parameters measured demonstrated clinically meaningful improvements after 12 months.
Phase transitions, elasticity and capillary waves in langmuir monolayers on water: An X-ray optical study (1991)

Abstract In this paper we investigate, by means of X-ray reflectivity at glancing angles, the phase transitions of Langmuir monolayers on water in different compounds (fatty acids and DPPC). We show that the determination of the profile of the electron density normal to the film provide two separate types of information: thicknesses and roughnesses. The thickness of the layer is directly related to the structure of the aliphatic medium and the roughness is due to thermally excited capillary waves. Our study clearly demonstrates that the transition between the so-called liquid-expanded to liquid-condensed phases is characterized by a significant discontinuity of the thickness of the aliphatic medium, whereas at the liquid-condensed to solid transition a strong decrease in the roughness is observed. This striking feature is attributed to the appearance of a rigidity constant of the monolayer in the solid phase.

Carrier frequency offset correction for uplink multi-user MIMO for next generation Wi-Fi (2015)

In this paper, we study carrier frequency offset estimation and correction for uplink multi-user MIMO (UL MU-MIMO) for Wi-Fi, where distributed stations (STAs) send multiple data streams to a common access point (AP) with multiple receive antennas. We provide a description of the proposed system, and propose a three-step approach using a joint phase estimation algorithm for carrier frequency synchronization that takes advantage of the existing pilot signals to deliver good performance and also has low complexity. We provide simulation results to demonstrate that the proposed approach incurs negligible performance loss due to carrier frequency offsets.
Scanning probe microscopy of biological samples and other surfaces (1988)

Scanning probe microscopes derived from the scanning tunnelling microscope (STM) offer new ways to examine surfaces of biological samples and technologically important materials. The surfaces of conductive and semiconductive samples can readily be imaged with the STM. Unfortunately, most surfaces are not conductive. Three alternative approaches were used in our laboratory to image such surfaces. 1. Crystals of an amino acid were imaged with the atomic force microscope (AFM) to molecular resolution with a force of order 10(-8) N. However, it appears that for most biological systems to be imaged, the atomic force microscope should be able to operate at forces at least one and perhaps several orders of magnitude smaller. The substitution of optical detection of the cantilever bending for the measurement by electron tunnelling improved the reliability of the instrument considerably. 2. Conductive replicas of non-conductive surfaces enabled the imaging of biological surfaces with an STM with a lateral resolution comparable to that of the transmission electron microscope. Unlike the transmission electron microscope, the STM also measures the heights of the features. 3. The scanning ion conductance microscope scans a micropipette with an opening diameter of 0.04-0.1 micron at constant ionic conductance over a surface covered with a conducting solution (e.g., the surface of plant leaves in saline solution).
Study of positioning methods in DVB-T single frequency networks (2012)

In this paper, we study a positioning method working in DVB-T single frequency networks (SFNs). These networks have several properties useful for positioning (synchronized emitters at fixed and known location, high SNR, OFDM signals containing pilot subcarriers). Thus, their signals may be used as signals-of-opportunity when the user enters a GNSS hostile environment (e.g. dense urban or indoor areas). One of the challenges to overcome is to distinguish the signals from different emitters. Here we suppose that the user can first compute his position by GNSS during an initialization phase, which is used for solving all the ambiguities concerning DVB-T emitters. After that, DVB-T signals can be used to aid positioning when the user enters a GNSS-blocked area, up to a limit case where all the GNSS satellites are not in view and only DVB-T signals are used for positioning. We tested this method by simulation, by adopting the free space loss model for the emitter attenuations and a two ray model for multipath. The obtained results show good performance if the receiver correctly associates the signal during the user's motion.
FACILITATION OF SPECIFIC TOLERANCE INDUCTION IN ADULT MICE BY RS-61443 (1992)

RS-61443 is an immunosuppressive agent that facilitates pancreatic islet allograft acceptance in two mouse strain combinations (BALB/c----CBA and C57Bl/6J----BALB/c). A remarkable feature of this agent is its ability to facilitate long-term graft acceptance after a short (30 days) period of treatment; following withdrawal of the agent 40-70% of islet allografts are maintained for an indefinite period. This long-term graft acceptance has been shown to result from specific tolerance induction in the recipient animal. The state of specific tolerance is an active rather than a passive form of tolerance, such as clonal deletion or anergy. Active tolerance induction is cyclosporine-sensitive, although cyclosporine enhances graft acceptance when used in combination therapy with RS-61443, this agent inhibits tolerance development under the influence of RS-61443.
Overtreatment rate after immediate local excision of suspected cervical intraepithelial neoplasia: A prospective cohort study (2022)

Immediate LLETZ does not result in overtreatment when applied on selected cases, especially after high-grade referral cytology and when high-grade lesion is also colposcopically suspected.
Reversible Data Hiding Scheme Based on Adjusting Pixel Modulation and Block-Wise Compression for Encrypted Images (2020)

Reversible data hiding in encrypted image (RDHEI) is a technique that can provide the security and invisibility of their own information during the acquisition and sharing of them among multi-users. Among which, parametric binary tree labelling (PBTL) is a novel technique designed to serve for high-capacity RDHEI. However, considering the local smoothness of the image, its potential redundancy room has not been fully explored. In this paper, we propose an improved PBTL-RDHEI scheme (IPBTL-RDHEI in short). In IPBTL-RDHEI, an adjusting pixel modulation strategy is considered to reduce the probability of the overflow of pixels, making more embeddable pixels usage to carry secret data. Moreover, a blockwise rearrangement and compression (BRC) mechanism is introduced to decrease the length of the required auxiliary information. Experimental results confirm that the proposed scheme is able to achieve an average embedding rate as large as 1.827 bpp when the block size is set to 3×3.

Removing the hidden data dependency of DIA with predicted spectral libraries (2019)

Data-Independent Acquisition (DIA) generates comprehensive yet complex mass spectrometric data, which imposes the use of data-dependent acquisition (DDA) libraries for deep peptide-centric detection. We here show that DIA can be redeemed from this dependency by combining predicted fragment intensities and retention times with narrow window DIA. This eliminates variation in library building and omits stochastic sampling, finally making the DIA workflow fully deterministic. Especially for clinical proteomics, this has the potential to facilitate inter-laboratory comparison. Significance of the Study Data-independent acquisition (DIA) is quickly developing into the most comprehensive strategy to analyse a sample on a mass spectrometer. Correspondingly, a wave of data analysis strategies has followed suit, improving the yield from DIA experiments with each iteration. As a result, a worldwide wave of investments in DIA is already taking place in anticipation of clinical applications. Yet, there is considerable confusion about the most useful and efficient way to handle DIA data, given the plethora of possible approaches with little regard for compatibility and complementarity. In our manuscript, we outline the currently available peptide-centric DIA data analysis strategies in a unified graphic called the DIAmond DIAgram. This leads us to an innovative and easily adoptable approach based on predicted spectral information. Most importantly, our contribution removes what is arguably the biggest bottleneck in the field: the current need for Data Dependent Acquisition (DDA) prior to DIA analysis. Fractionation, stochastic data acquisition, processing and identification all introduce bias in the library. By generating libraries through data independent, i.e. deterministic acquisition, stochastic sampling in the DIA workflow is now fully omitted. This is a crucial step towards increased standardization. Additionally, our results demonstrate that a proteome-wide predicted spectral library can surrogate an exhaustive DDA Pan-Human library that was built based on 331 prior DDA runs.
Gene Expression Profile of the Aging Process in Rat Liver: Normalizing Effects of Growth Hormone Replacement (2001)

The mechanisms that control life span and age-related phenotypes are not well understood. It has been suggested that aging or at least some of its symptoms are related to a physiological decline in GH levels with age. To test this hypothesis, and to improve our understanding of the cellular and molecular mechanisms behind the aging process, we have analyzed age-induced changes in gene expression patterns through the application of DNA chip technology. In the present study, the aging process was analyzed in rat liver in the presence or absence of GH replacement. Out of 3,000 genes printed on the microarrays, approximately 1,000 were detected in the rat liver. Among these, 47 unique transcripts were affected by the aging process in male rat livers. The largest groups of age-regulated transcripts encoded proteins involved in intermediary metabolism, mitochondrial respiration, and drug metabolism. Approximately 40% of the differentially expressed gene products were normalized after GH treatment. The majority of those transcripts have previously not been shown to be under GH control. The list of gene products that showed normalized expression levels in GH-treated old rats may shed further insight on the action and mechanism behind the positive effects of GH on, for example, fuel metabolism and body composition observed in different animal and human studies.
MONO1001: A source for singly charged ions applied to the production of multicharged fullerene beams (2004)

The present article reports on a recent study of the production of multiply charged fullerene beams based on an electron cyclotron resonance (ECR) ion source (ECRIS). As collision studies in fundamental physics are demanding intense beams of multiply charged ions of small molecules, clusters, and particularly of fullerenes, we have further developed the ion source ECRIS MONO1000 [P. Jardin et al., Rev. Sci. Instrum. 73, 789 (2002)], originally devoted to produce singly charged ions, towards the production of multiply charged fullerene beams. In this article, the test measurements performed at the Electrostatic Ion Storage Ring Århus rf power (ELISA) facility will be described. Typical mass spectra (from pure C60 and C70 powder) will be shown and the influence of several source parameters (rf power, support gas, gas pressure,…) will be discussed specifying the conditions necessary for an optimum ion source operation.
Pattern of care study for treatment of ovarian cancer patients among Japanese gynecologists. A Japanese Gynecologic Oncology Group (JGOG) study (2006)

15029 Background: The Japanese Society of Gynecologic Oncology started a training program for the subspecialty of board certified gynecologic oncologists in 2005. This study aimed to assess the attitude of Japanese gynecologists for the treatment of ovarian cancer in pre-gynecologic oncologist era. Methods: The JGOG distributed a survey to 217 member institutions in January 2005. The principal investigator (PI) of each institution answered 33 questionnaires regarding diagnostic, surgical and chemotherapy issues. The survey was returned from 156 institutions (71.9%). Results: Hospital settings were general (44%), academic (44%), Cancer Center (8%), or private (4%). Only two of PIs were medical oncologists and rests of them were gynecologists. As the staging procedure in early ovarian cancer, 67% institutions do systemic pelvic lymphadenectomy (LNX) but 22% do only sampling. For the paraaortic nodes, 36% do systemic LNX and 10% do sampling below renal vein, and 14% do LNX and 12% do sampling below inferior mesenteric artery. However, intraabdominal explorations such as multiple peritoneal biopsies have been done only less than 30% except for omentectomy (90%). With regard to the surgery for advanced ovarian cancer, 57% institutions do not do any intestinal resection and anastomosis during the primary surgery. Among them 7% of institutions prefer neoadjuvant chemotherapy (no debulking at all) for advanced ovarian cancer. However, 84% of the institutions do interval debulking and 57% of them are quite aggressive for the procedure. These results demonstrate the high expectation that chemotherapy may reduce the aggressiveness of surgery for advanced ovarian cancer. In terms of chemotherapy for the high-risk early and advanced ovarian cancer, taxane plus platinum is the most used regimen (93–95%). However, 45% of institutions prefer different regimen for clear cell carcinoma. CPT-11 is the most used (88.6%). Intraperitoneal chemotherapy has been performed in 28.2% of institutions. 37.2% of institutions do consolidation chemotherapy. Conclusions: This is an important base-line information to assess the pattern of care for ovarian cancer patients in the era before gynecologic oncologist subspecialty is applicable in Japan. No significant financial relationships to disclose.
Early Postsurgery Experience of Prostate Cancer Patients and Spouses (2000)

Physicians, nurses, social workers, and other health professionals working with patients before and after prostatectomies may assist couples to prepare better for the early recovery period by being both sensitive to the men's need to recover physical capacity quickly while helping them to understand that recovery takes time. Accurate information about expected periods of irritability, side effects, and possible complications would diminish the likelihood of distress during this period.
