Influence of ceramic disk material, surface hemispheres, and SBF volume on in vitro mineralization (2015)

Calcium phosphate ceramics are the main mineral constituents of bone and teeth and have therefore been extensively investigated for bone regenerative applications. In the current study, the effect of disk material, surface geometry, and SBF volume on mineralization capacity was investigated. Hemispherical concavities were created on the surfaces of disks made of different materials (i.e., hydroxyapatite (HA), β-tricalcium phosphate (β-TCP), biphasic calcium phosphate (BCP) and titanium (Ti)) which were sintered at 1200 °C. Mineralization of CaP was assessed on disk surfaces after immersion of the samples in different volumes of simulated body fluid (SBF) up to 14 days by means of calcium assay and scanning electron microscopy (SEM). This study showed that different SBF volumes have different effects on mineralization, with an optimum material/liquid ratio of 5 mL of SBF per cm(2) . Additionally, at this volume, apparent differences based on disk material became obvious. Evidently, surface hemispherical concavities acted as initiator areas for nucleation and crystal growth.
Multiple holographic lenses in silver halide emulsion (1985)

A detailed study of transmission holograms recorded by one plane reference wave and N cylindrical waves (where N varies from 1 to a large number) is reported. The aim is to investigate both experimentally and theoretically the interactions caused by the presence of several superimposed gratings in a volume hologram. The material used is AGFA 8E56 HD recorded at 514.5 nm using an Ar-ion laser, and processing is the same as that reported recently by Slinger et al.1 At recording the cylindrical sources are sufficiently far from the recording plate so that they can be regarded as locally plane waves at every point through the emulsion.
Analysis of the iridals in rhizome extracts ofIris variegataLinn. (2004)

Fractionation of the lipid extract from rhizomes of Iris variegata Linn. resulted in the isolation of one new and four known iridals. The latter were identified by comparison with authentic standards and NMR-spectroscopic analyses as 21-hydroxyiridal 1, 21-hydroxy-10-deoxyiridal 2, 16-hydroxyiridal 3 and 22-methyl-gamma-cycloiridal 4. The (R) configuration of C21 in compound 2 was determined by the exciton chirality method. The same stereochemistry has previously been found for the appropriate moieties in 1 and 3. Based on its spectroscopic properties the new triterpenoid was shown to be the 23-hydroxyiridal 5.

Probabilistic Risk Model for Organ Doses and Acute Health Effects of Astronauts on Lunar Missions (2009)

Exposure to large solar particle events (SPEs) is a major concern during EVAs on the lunar surface and in Earth-to-Lunar transit. 15% of crew times may be on EVA with minimal radiation shielding. Therefore, an accurate assessment of SPE occurrence probability is required for the mission planning by NASA. We apply probabilistic risk assessment (PRA) for radiation protection of crews and optimization of lunar mission planning.
An Efficient Multihoming Scheme to Support Seamless Handover in SDN-based Network Mobility (2021)

Multihoming technology is widely used to contribute reliability and performance improvement in network mobility by providing multiple connections to mobile routers. The mobile router may have to choose a suitable connection among available connections for the mobile node. In this paper, we propose a handover method for network mobility that utilizes the multihoming feature of a mobile router in SDN-based network mobility (SDN-MNEMO). We newly introduce an access router (AR) selection method to select the optimal AR for seamless handover in multihoming network mobility. The optimal AR is selected considering throughput of the backhaul links and downlink bit rate information of the available ARs in the mobility network. Using an experimental testbed, we present a thorough handover performance evaluation of our proposed scheme, and compare it with a conventional SDN-NEMO scheme. The results show that the proposed scheme outperforms the conventional scheme while achieving seamless handover. The handover delay in the conventional scheme is 7.15s compared to 72ms in the proposed scheme. Also, average throughput for the mobile node reached up to 950Kbps and it remained constant during the handover for the proposed scheme.
Architectural support for scalable speculative parallelization in shared-memory multiprocessors (2000)

Speculative parallelization aggressively executes in parallel codes that cannot be fully parallelized by the compiler. Past proposals of hardware schemes have mostly focused on single-chip multiprocessors (CMPs), whose effectiveness is necessarily limited by their small size. Very few schemes have attempted this technique in the context of scalable shared-memory systems.

Development of EUV resists at Selete (2009)

This paper summarizes the development of EUV resists at Semiconductor Leading Edge Technologies (Selete): the benchmarking results of more than 160 EUV resists from resist manufacturers using the small field exposure tool (SFET) and the selection of the Selete standard resists (SSR) for the SFET. We discuss the current status of EUV resist performance compared to the targets for 32-nm half-pitches (hp) concerning resist sensitivity, ultimate resolution, and line-width-roughness (LWR). In addition we show the screening results of new resin materials.
Effects of propolis and gamma‐cyclodextrin on intestinal neoplasia in normal weight and obese mice (2016)

Obesity is associated with colorectal cancer (CRC). This effect might be attributed to adipokine-supported signaling. We have established that propolis suppresses survival signaling in CRC cells in vitro; therefore, we ascertained the ability of a propolis supplement to modulate intestinal neoplastic development in C57BL/6J-ApcMin/+/J mice in the lean and obese state. To induce obesity, mice were fed with a Western diet containing 40% fat. Since the propolis supplement includes gamma-cyclodextrin, the interventions included diets supplemented with or without gamma-cyclodextrin. The animals were administered the following diets: (1) control diet, (2) control diet/gamma-cyclodextrin, (3) control diet/propolis, (4) Western diet, (5) Western diet/gamma-cyclodextrin, and (6) Western diet/propolis. Western diet, resulting in obesity, accelerated neoplastic progression, as evidenced by the larger size and higher grade dysplasia of the neoplasms. In the context of normal weight, gamma-cyclodextrin and propolis affected neoplastic progression, as determined by the size of the lesions and their grade of dysplasia. A statistically significant decrease in the number of adenomas was detected in mice fed a control diet with the propolis supplement (61.8 ± 10.6 vs. 35.3 ± 7.6, P = 0.008). Although there was no significant difference in the polyp numbers between the six groups, the mice with the lowest number and size of adenomas were those fed a Western diet with gamma-cyclodextrin. This unexpected outcome might be explained by the increased levels of apoptosis detected in the intestinal tissues of these obese mice. We posit that butyrate derived from the metabolism of gamma-cyclodextrin may contribute to the decreased neoplastic burden in the context of obesity; however, future studies are required to address this possibility.
Collusion-resistant fingerprints from WBE sequence sets (2005)

Digital fingerprinting protects multimedia content from being used for unauthorized purposes. One cost-effective strategy to attack digital fingerprints is collusion, where several colluders average their individual copies to disrupt the underlying fingerprints. In this work, we propose that fingerprints can be constructed using sequence sets satisfying the Welch bound equality (WBE). We further propose a detection algorithm utilizing sphere decoding that identifies the colluders from the colluded signal. We evaluate the performance of the proposed WBE-based anti-collusion codes (ACC) fingerprints with our proposed detection algorithm through simulations, and compare the performance of our scheme against orthogonal fingerprints and the BIBD anti-collusion codes proposed earlier. Simulation results show that the proposed WBE-based ACC and detection algorithm have better performance than BIBD-based ACC under the same configuration.
Group II innate lymphoid cells and microvascular dysfunction from pulmonary titanium dioxide nanoparticle exposure (2018)

These results provide evidence that the uterine microvascular dysfunction that follows pulmonary ENM exposure may be initiated via activation of lung-resident ILC2 and subsequent systemic Th2-dependent inflammation.
Adaptive phase locked loop for video signal sampling (2003)

Presents a new BiCMOS adaptive phase locked loop (PLL) circuit for a video signal sampling system. This circuit significantly decreases the acquisition time of a standard second-order charge-pump PLL without affecting its noise performance in the locked state. The adaptation consists of tuning the bandwidth of the loop filter during signal acquisition. Tuning is achieved by adjusting the transconductance of an operational transconductance amplifier (OTA). The adaptive algorithm is reviewed for the general case of PLLs in terms of the circuit components and system requirements.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Los estudios antropológicos en el marco de la Universidad Nacional (2005)

Y en razón de ello cuáles son las perspectivas actuales de la antropología en el país.
Data from Unique DNA Methylation Patterns Distinguish Noninvasive and Invasive Urothelial Cancers and Establish an Epigenetic Field Defect in Premalignant Tissue (2023)

&lt;div&gt;Abstract&lt;p&gt;Urothelial cancer (UC) develops along two different genetic pathways, resulting in noninvasive or invasive tumors. However, it is unknown whether there are also different epigenetic pathways in UC. UC is also characterized by a high rate of recurrence, and the presence of a field defect has been postulated. In this study, we compared the DNA methylation patterns between noninvasive and invasive UC and the DNA methylation patterns between normal-appearing urothelium from bladders with cancer and urothelium from cancer-free bladders. We used the Illumina GoldenGate methylation assay at 1,370 loci in 49 noninvasive urothelial tumors, 38 invasive tumors with matched normal-appearing urothelium, and urothelium from 12 age-matched UC-free patients. We found distinct patterns of hypomethylation in the noninvasive tumors and widespread hypermethylation in the invasive tumors, confirming that the two pathways differ epigenetically in addition to genetically. We also found that 12% of the loci were hypermethylated in apparently normal urothelium from bladders with cancer, indicating an epigenetic field defect. X-chromosome inactivation analysis indicated that this field defect did not result in clonal expansion but occurred independently across the urothelium of bladders with cancer. The hypomethylation present in noninvasive tumors may counterintuitively provide a biological explanation for the failure of these tumors to become invasive. In addition, an epithelium-wide epigenetic defect in bladders with cancer might contribute to a loss of epithelial integrity and create a permissible environment for tumors to arise.

Non-invasive recording of His bundle potential in man. Simplified method. (1975)

In 6 cases with sinus rhythm and one with atrial fibrillation, the bipolar surface electrocardiograms were taken through band pass filters simultaneously with the intracavitary His bundle electrogram, and averaged using a signal processer. By these relatively simplified procedures 'blips' considered to be derived from His bundle potentials between PR segments could be recorded. It was found that 'blips' originating from the His bundle were recorded most distinctly when a cathode was applied to the posterior mid-line and an anode to the sternum, both at the level of the fourth intercostal space. In some instances it was possible to record 'blips' probably derived from the bundle-branches. To identify the onset of ventricular potentials it was necessary to refer to the surface electrocardiograms taken with a usual time constant. The interval from the onset of 'blip' to the onset of ventricular activity (BV) agreed perfectly with the directly recorded His bundle to ventricle conduction time (HV) in 6 out of 7 cases investigated, and in the remaining case this interval was found to be only 1 ms longer than the HV.
Phenyl Isopropyl Adenosine Alters Fetal Electrocorticogram, Breathing and Heart Rate (1986)

Six fetal sheep were equipped with intratracheal, amniotic and vascular catheters and electrocorticogram electrodes to study the effect of phenyl isopropyl adenosine (PIA) on electrocorticogram and fetal breathing movements. Three animals had functioning electrocardiogram electrodes. During 1,000-min control periods, low-voltage high-frequency (LVHF) electrocorticogram predominated 60 +/- 1% (mean +/- SEM) of total time. Fetal breathing movements occurred 34 +/- 1% of total time and only during LVHF electrocorticogram. PIA 0.125 mg was given intravenously to the fetus during established LVHF electrocorticogram and fetal breathing movements. LVHF electrocorticogram converted in 58 +/- 16 s to high-voltage low-frequency (HVLF) electrocorticogram which persisted for 10 +/- 3 min. This was followed by a third electrocorticogram pattern for 119 +/- 12 min. Fetal breathing movements ceased in 47 +/- 25 s and did not recur for 150 +/- 20 min. An increase in fetal breathing movements (59 +/- 2% of total time) occurred between 300 and 800 min (control 34 +/- 1%, p less than 0.05). Electrocardiogram demonstrated a decrease in heart rate from 170 +/- 6 to 90 +/- 6 beats per min with return to baseline in 113 +/- 49 min. No significant changes occurred in blood gases. We conclude that fetal electrocorticogram, fetal breathing movements and heart rate are influenced by adenosine.
High-energy conversion efficiency amorphous silicon solar cells by photochemical vapor deposition (1985)

Hydrogenated amorphous silicon solar cells were fabricated by photochemical vapor deposition. A three-separate-chamber system was newly developed to reduce the contamination of the dopant elements as well as oxygen or water originated by the loading and unloading procedure. Wide optical band-gap hydrogenated amorphous silicon carbide was prepared using acetylene (C2H2) for the p layer. The deposition conditions for each layer were optimized and the highest-energy conversion efficiency of 9.64% was obtained. This high conversion efficiency was mainly attributed to the large short-circuit current which indicated that the quality of the i layer is reasonably good.

Optimal-efficiency control for constant-power operation of phase-decoupling permanent-magnet brushless motor drives (2002)

In this paper, a control approach to optimize the system efficiency of phase-decoupling (PD) permanent magnet (PM) brushless motor drives during constant-power operation is presented. The approach is to adaptively adjust the advanced conduction angle to minimize the total system losses for a given operation point in the constant power region. The corresponding minimum total losses are determined by minimizing the input current for a fixed voltage source. Both computer simulation and experimental results are given for illustration.
The Effect of Politicians’ Personality on Their Media Visibility (2018)

While being frequently covered in the news media is key to political success, previous research demonstrates that some politicians are systematically more visible in the media than others. The current study advances our understanding of which politicians gain higher media visibility by exploring the effects of their personality traits. Utilizing a unique sample of 339 incumbent politicians in three countries, we find that the two personality traits that speak directly to one’s interpersonal orientation—agreeableness and extraversion—affect visibility, with less agreeable and more extraverted politicians appearing more frequently in the news. We also find that open to experience and emotionally stable politicians get covered more frequently and that being highly conscientious predicts media visibility in some cases, but not in others. Politicians high on these traits, we argue, enjoy an inherent advantage in the competition for the media’s attention.
Disentangled Representation Learning GAN for Pose-Invariant Face Recognition (2017)

The large pose discrepancy between two face images is one of the key challenges in face recognition. Conventional approaches for pose-invariant face recognition either perform face frontalization on, or learn a pose-invariant representation from, a non-frontal face image. We argue that it is more desirable to perform both tasks jointly to allow them to leverage each other. To this end, this paper proposes Disentangled Representation learning-Generative Adversarial Network (DR-GAN) with three distinct novelties. First, the encoder-decoder structure of the generator allows DR-GAN to learn a generative and discriminative representation, in addition to image synthesis. Second, this representation is explicitly disentangled from other face variations such as pose, through the pose code provided to the decoder and pose estimation in the discriminator. Third, DR-GAN can take one or multiple images as the input, and generate one unified representation along with an arbitrary number of synthetic images. Quantitative and qualitative evaluation on both controlled and in-the-wild databases demonstrate the superiority of DR-GAN over the state of the art.
A binaural room impulse response database for the evaluation of dereverberation algorithms (2009)

This paper describes a new database of binaural room impulse responses (BRIR), referred to as the Aachen impulse response (AIR) database. The main field of application of this database is the evaluation of speech enhancement algorithms dealing with room reverberation. The measurements with a dummy head took place in a low-reverberant studio booth, an office room, a meeting room and a lecture room. Due to the different dimensions and acoustic properties, it covers a wide range of situations where digital hearing aids or other hands-free devices can be used. Besides the description of the database, a motivation for using binaural instead of monaural measurements is given. Furthermore an example using a coherence-based dereverberation technique is provided to show the advantage of this database for algorithm evaluation. The AIR database is being made available online.
