Expression of multiple thyroid hormone receptor mRNAs in human oocytes, cumulus cells, and granulosa cells (1997)

Thyroid hormones have diverse effects on ovarian function. We examined the expression of thyroid hormone receptor (TR) mRNAs (including TRalpha-1, TRbeta-1, TRbeta-2, and c-erbAalpha-2 isoforms) in three types of cells from human follicles, and determined the concentration of free tri-iodothyronine (T3) present in human follicular fluid. Human failed-fertilized oocytes, granulosa (GC) and cumulus (CC) cells from patients of the in-vitro fertilization (IVF) programme at Alliant Hospital Fertility Center were used to detect TR mRNA expression using reverse transcription-polymerase chain reaction (RT-PCR) followed by Southern blot analysis. Human spermatozoa were also analysed to determine whether results obtained with CC would be affected by the presence of spermatozoa. beta-Actin mRNA was amplified in each cell type as a positive control for the RT-PCR. Our results show that human oocytes express TRalpha-1, TRbeta-1, TRbeta-2, and c-erbAalpha-2 mRNAs and that these same isoforms are expressed in both human granulosa cells and cumulus cells. No differences were detected in the apparent amounts of RT-PCR products when comparing GC with CC, suggesting a similar pattern of expression of these RNAs. beta-actin mRNA was detected in spermatozoa, but TRalpha-1 expression was not detectable. The concentrations of free T3 measured in follicular fluid were similar to, or slightly below, those in serum of euthyroid patients. These data demonstrated that several isoforms of TR mRNA are expressed in the human oocyte, and hence thyroid hormone may have direct affects on the oocyte, as well as on GC and CC. In addition thyroid hormone may have indirect effects on the oocytes via the CC.
Evaluation of a pH-Sensitive Polymer for Gravel-Packing Operations (2001)

Abstract Anionic polymers such as polyacrylic acid, polymethacrylic acid, and their derivatives are known to show pH sensitive rheology. Rheological data is presented for a polyacrylic acid type polymer as a function of polymer concentration, pH, shear rate, and temperature. The effects of monovalent and divalent ions on the rheology are also presented. Core flow experiments were conducted on Berea sandstone cores. Fluid loss and filter cake stability was investigated at an overbalance pressure of 100 psi. Its effectiveness was compared with that of a conventional carrier fluid (HEC) used for gravel packing. It was found that the viscosity of the polymer is strongly dependent upon the pH of the solution. At higher pH values (&gt;6), the polymer viscosity reached a high value that is sufficient to suspend most gravel. Hydrochloric acid breaks this high viscosity to a low value (&lt;5 cp) at pH values below 2. The thickening and thinning with pH was found to be reversible. The effect of temperature on the rheological properties was not significant. Compatibility tests showed that the polymer was compatible with most brines (NaCl, NH4Cl, and KCl) used for field applications. Core flow results indicated that the filtration rate was low (&lt;9 ml/hr) compared to that of HEC (106 ml/hr), at an overbalance pressure of 100 psi. The retained permeability of the core was found to be 80% and 40% after using the polymer and HEC, respectively. The invasion depth is also shorter than that of HEC due to the formation of a stable filter cake. Our evaluation study shows that this anionic polymer would be an excellent non-damaging carrier fluid for gravel packing. It has excellent rheological and suspension properties and is easily broken down with a mild acid wash before flowback.
An Efficient Access Privacy Protocol for Healthcare Patient Information System (2019)

This paper discusses different healthcare information access record systems development techniques and sharing techniques with patient and physician. It provides a theoretical study to find out the latest techniques used by healthcare information sharing organizations which have a legal access and keep the patient data secured. We have proposed a system, which give access to the electronic record of a patient by using two-factor authentication protocol which is an efficient and more secure access method. This system is for both literate and illiterate people, which requires the National Identity Card Number (CNIC) and mobile device. The physician needs computer or mobile phone to access the model services. The electronic medical records are stored in a database which can be accessed by the authorized person physician or patient through two-factor authentication protocol. Each individual accessed through the two-factor authentication process, which makes this system secure and non-vulnerable. It provides a onetime password, which is only valid for only one login session.
VMmark: A Scalable Benchmark for Virtualized Systems (2006)

The increasing speed of computing resources coupled with the rise of robust and flexible virtual machine technology creates opportunities for consolidating multiple, variably loaded systems onto a single physical server. Traditional server benchmarks, which focus on a single workload, do not capture the system behavior induced by multiple virtual machines. An appropriate virtual machine benchmark should employ realistic, diverse workloads running on multiple operating systems. The benchmark should generate an easily understandable metric that scales with underlying system capacity using a controlled strategy based on a combination of increased individual workload scores and running an increasing number of workloads. This paper presents a tile-based benchmark consisting of several familiar workloads running simultaneously in separate virtual machines. Each workload component is based upon a single-system benchmark running at less than full utilization. This collection of different workloads is aggregated into a unit of work referred to as a tile. The performance of each workload is measured and used to form an aggregate score for the tile. The scores generated when running multiple tiles simultaneously may be summed to increase the overall benchmark score.
Influence of surface-activated reaction kinetics on low-pressure chemical vapor deposition conformality over micro features (1993)

The coupled effect of molecular scattering and surface-activated reactions on low-pressure chemical vapor deposition (LPCVD) film conformality is investigated. Using a single-precursor two-step surface-activated deposition as an example, film conformality can be found to depend on two first-principle dimensionless parameters–Sc, the intrinsic sticking coefficient, and Sa, the surface saturation factor. An analytical integral material balance formulation, developed for the feature-scale molecular transport, is solved numerically in a wide range of Sc and Sa. The results show that film conformality generally improves with decreasing Sc and increasing Sa. With Sc fixed in most LPCVD processes (due to the nature of the precursor species), the ability to control Sa in the process becomes the key to conformal deposition. The intrinsic surface-activated deposition rate expression shows no apparent reaction order. Therefore, previously reported Monte Carlo schemes and integral-differential models employing a single sticking parameter or a fixed reaction order to characterize LPCVD step coverage behavior are applicable only in limited cases. The two-parameter model has been found useful in understanding the H2-reduced tungsten CVD process, for which the first-principle parameters can be determined from kinetic data reported in the literature.
Custom implant design for patients with cranial defects (2002)

Three-dimensional image reconstruction and rapid prototyping models improve defect evaluation, treatment planning, implant design, and surgeon accuracy. It is found that both 3-D imaging and physical models are helpful for the evaluation of cranial defects, treatment planning, and custom implant design. While 3-D imaging can be used on a routine basis, the physical skull models could be a useful additional tool, especially when the cranial defects are rare, unusual, or difficult. In this case, the introduction of a rapid prototyping stereolithographic medical model for manufacturing a large cranioplasty implant is considered to be an improvement over other traditional techniques. Because of the accuracy of the physical model, the surgeon has a good understanding of the cranial defect and precise fitting implants can be fabricated in order to re-establish skull contours for the patient. In addition, the excellent fitting and fixation techniques of cranioplasty have reduced operating time significantly.
The ZIM domain mediates homo‐ and heteromeric interactions between Arabidopsis JAZ proteins (2009)

Discovery of the jasmonate ZIM-domain (JAZ) repressors defined the core jasmonate (JA) signalling module as COI1-JAZ-MYC2, and allowed a full view of the JA signalling pathway from hormone perception to transcriptional reprogramming. JAZ proteins are repressors of MYC2 and targets of SCF(COI1), which is the likely jasmonate receptor. Upon hormone perception, JAZ repressors are degraded by the proteasome releasing MYC2 and allowing the activation of JA responses. All members of the JAZ family share two conserved domains, the Jas motif, required for JAZ interactions with MYC2 and COI1, and the ZIM domain, the function of which is so far unknown. Here, we show that the ZIM domain acts as a protein-protein interaction domain mediating homo- and heteromeric interactions between JAZ proteins. These JAZ-JAZ interactions are independent of the presence of the hormone. The observation that only a few members of the JAZ family form homo- and heteromers may suggest the relevance of these proteins in the regulation of JA signalling. Interestingly, the JAZ3DeltaJas protein interacts with several JAZ proteins, providing new clues to understanding the dominant JA insensitivity promoted by truncated JAZDeltaJas proteins. We also provide evidence that the Jas motif mediates the hormone-dependent interaction between Arabidopsis JAZ3 and COI1, and further confirm that the Jas motif is required and sufficient for Arabidopsis JAZ3-MYC2 interaction. Finally, we show that interaction with MYC2 is a common feature of the JAZ family, as most JAZ proteins can bind MYC2 in pull-down and yeast two-hybrid assays.
Enhancement of mechanical strength and in vivo cytocompatibility of porous β-tricalcium phosphate ceramics by gelatin coating (2016)

In an attempt to prepare scaffolds with porosity and compressive strength as high as possible, we prepared porous β-tricalcium phosphate (TCP) scaffolds and coated them with regenerative medicine-grade gelatin. The effects of the gelatin coating on the compressive strength and in vivo osteoblast compatibility were investigated. Porous β-TCP scaffolds were prepared and coated with up to 3 mass% gelatin, and then subjected to thermal cross-linking. The gelatin-coated and uncoated scaffolds were then subjected to compressive strength tests and implantation tests into bone defects of Wistar rats. The compressive strength increased by one order of magnitude from 0.45 MPa for uncoated to 5.1 MPa for gelatin-coated scaffolds. The osteoblast density in the internal space of the scaffold increased by 40 % through gelatin coating. Coating porous bone graft materials with gelatin is a promising measure to enhance both mechanical strength and biomedical efficacy at the same time.
TNF-  antagonists beyond approved indications: stories of success and prospects for the future (2010)

Tumour necrosis factor alpha (TNF-α) is a key molecule of the inflammatory response and data derived from studies in experimental animal models and humans suggest that TNF-α may be implicated in the pathogenesis of various autoimmune and non-infectious inflammatory conditions. Over the past decade pharmaceutical agents directed against TNF-α (infliximab, adalimumab and etanercept) have been widely and successfully employed for the management of rheumatoid arthritis (RA), ankylosing spondylitis (AS), psoriasis, psoriatic arthritis, juvenile idiopathic arthritis and inflammatory bowel disease, whereas two novel anti-TNF-α agents, golimumab and certolimumab pegol, recently entered the market for the treatment of RA, AS, Crohn's disease and psoriasis. Encouraged by the positive results obtained from the use of TNF-α antagonists in terms of efficacy and safety and due to the increasingly accumulating evidence regarding the implication of TNF-α in the pathogenesis of numerous disorders, anti-TNF-α agents have been considered for the management of diseases other than the ones they were initially approved for. Although in the case of multiple sclerosis and chronic heart failure the outcome from the administration of TNF-α blockers had been less than favourable, in other cases of non-infectious inflammatory conditions the response to TNF-α inhibition had been fairly beneficial. More specifically, according to well-documented clinical trials, anti-TNF-α agents exhibited favourable results in Behçet's disease, non-infectious ocular inflammation, pyoderma gangrenosum and hidradenitis suppurativa. In this review we discuss the successful outcomes as well as the prospects for the future from the off-label use of TNF-α antagonists.
Design considerations and loss analysisofzero-voltage switching boost converter (2001)

A novel zero-voltage switching (ZVS) boost converter for medium- and high-power applications is proposed. Compared to conventional hard switching boost converters, the switching losses are decreased by a factor of 3 to 4. A design procedure is proposed, based on the minimisation of the total losses in the switch. It is shown that variations of operating frequency, turn-off current and voltage rise time do not affect the control algorithm or the design procedure, even for a wide range of loading conditions and input voltage. A 3 kW prototype using IGBTs is simulated (PSPICE) and developed. The efficiency obtained is more than 90% for load values higher than 20% of full load, and attains 95% for full load. Advantages of the circuit include zero-voltage-zero-current turn-on and zero-voltage turn-off for a wide range of line voltage and load; switching conditions do not depend on the load. The reliable control strategy makes the proposed ZVS boost converter attractive for medium-power applications where IGBTs are used predominantly.
A Simple and Optimized Method of Producing Silanized Surfaces for FISH and Replication Mapping on Combed DNA Fibers (2008)

Molecular combing of DNA is an extremely powerful DNA fiber–stretching technique that is often used in DNA replication and genome stability studies. Optimal DNA combing results mainly depend on the quality of the silanized surfaces onto which fibers are stretched. Here we describe an improved method of liquid-phase silanization using trimethoxy-octenylsilane/n-heptane as novel silane/solvent combination. Our simple method produces homogenously modified coverslips in a reproducible manner, but does not require any sophisticated or expensive equipment in comparison to other known silanization protocols. However, DNA fibers were combed onto these coverslips with very good high-density alignment and stayed irreversibly bound onto the surfaces after various denaturing treatments, as required for different immunofluorescent detection of DNA with incorporated modified nucleotides or FISH.
BIM‐Based E‐Procurement: An Innovative Approach to Construction E‐Procurement (2015)

This paper presents an innovative approach to e-procurement in construction, which uses building information models (BIM) to support the construction procurement process. The result is an integrated and electronic instrument connected to a rich knowledge base capable of advanced operations and able to strengthen transaction relationships and collaboration throughout the supply chain. The BIM-based e-procurement prototype has been developed using distinct existing electronic solutions and an IFC server and was tested in a pilot case study, which supported further discussions of the results of the research.
A new method for capture recognition in human heart (1992)

Until now capture recognition of evoked potentials using a single electrode is limited by electrode polarisation. Electronic measures have not been successful due to the variability of the after potential. However, it is shown, that a porous coating — e.g. of TiN or Ir — reduces the after potential significantly. Using coated electrodes an autoshort between stimulus and ECG of about 80 ms decreases the offset potential to zero enabling a reliable capture recognition via the normal detection channel.
Event Detection and Highlight Detection of Broadcasted Game Videos (2015)

Efficient access of game videos is urgently demanded due to the emergence of live streaming platforms and the explosive numbers of gamers and viewers. In this work we facilitate efficient access from two aspects: game event detection and highlight detection. By recognizing predefined text displayed on screen when some events occur, we associate game events with time stamps to facilitate direct access. We jointly consider visual features, events, and viewer's reaction to construct two highlight models, and enable compact game presentation. Experimental results show the effectiveness of the proposed methods. As one of the early attempts on analyzing broadcasted game videos from the perspective of multimedia content analysis, our contributions are twofold. First, we design and extract game-specific features considering visual content, event semantics, and viewer's reaction. Second, we integrate clues from these three domains based on a psychological approach and a data-driven approach to characterize game highlights.
3D modeling and motion parallax for improved videoconferencing (2016)

We consider a face-to-face videoconferencing system that uses a Kinect camera at each end of the link for 3D modeling and an ordinary 2D display for output. The Kinect camera allows a 3D model of each participant to be transmitted; the (assumed static) background is sent separately. Furthermore, the Kinect tracks the receiver’s head, allowing our system to render a view of the sender depending on the receiver’s viewpoint. The resulting motion parallax gives the receivers a strong impression of 3D viewing as they move, yet the system only needs an ordinary 2D display. This is cheaper than a full 3D system, and avoids disadvantages such as the need to wear shutter glasses, VR headsets, or to sit in a particular position required by an autostereo display. Perceptual studies show that users experience a greater sensation of depth with our system compared to a typical 2D videoconferencing system.
A 42/84-GHz Multi-Ring Rotary Traveling-Wave Oscillator (2019)

A multi-ring rotary traveling-wave oscillator (RTWO) is presented. The oscillation frequency of the main RTWO ring is designed for 42-GHz with 2-GHz tunability. Multiphase signals generated in the main RTWO ring drive doubler circuits to generate second harmonic signals. The transformer used in each doubler circuit produces differential signals that are injected into the outer ring. Differential signals in the secondary terminals of the transformers are combined by coupled co-planar strip-line to support traveling-wave in the second ring. Bi-CMOS 0.13-μm technology is used to design and implement the multiring RTWO circuit. The chip area is about 0.78-mm by 0.75mm. Total power consumption is 68-mW. SiGe HBT has been preferred over nMOS transistors to implement the gain stages, frequency doublers and the buffer circuits due to high f <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">T</sub> and f <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">max</sub> of the SiGe HBTs. The measured frequency of oscillation is 42.24-GHz and 84.48-GHz with 5.6% tuning range and measured phase noise at the main RTWO ring is -97.5 dBc/Hz at 10 MHz.
Graph rewrite systems for program optimization (2000)

Graph rewrite systems can be used to specify and generate program optimizations. For termination of the systems several rule-based criteria are developed, defining exhaustive graph rewrite systems . For nondeterministic systems stratification is introduced which automatically selects single normal forms. To illustrate how far the methodology reaches, parts of the lazy code motion optimization are specified. The resulting graph rewrite system classes can be evaluated by a uniform algorithm, which forms the basis for the optimizer generator OPTIMIX. With this tool several optimizer components have been generated, and some numbers on their speed are presented.
Characterization of the Reflection and Dispersion Properties of 'Mushroom'-related Structures and their Applications to Antennas (2012)

The conventional mushroom-like Sievenpiper structure is re-visited in this thesis and a\nrelationship is established between the dispersion and reflection phase characteristics of the structure. It is shown that the reflection phase frequency at which the structure behaves as a Perfect Magnetic Conductor (PMC) can be predicted for varying angles of incidence from the modal distribution in the dispersion diagrams and corresponds to the supported leaky modes within the light cone. A methodology to independently tune the location of the PMC frequency point with respect to the surface wave band-gap location is then presented. The influence of having said PMC frequency point located inside or outside the surface wave band-gap on a dipole radiation pattern is then studied numerically. It is demonstrated that the antenna exhibits a higher gain when the PMC frequency and band-gap coincide versus when they are separated. Two design cases are then presented for when the aforementioned properties coincide and are separated and a gain improvement of 1.2 dB is measured for the former case.
