Feedforward Active Noise Control with Coherence-Adjusting Filter for Improving Noise Reduction Performance under Low-Coherence Condition (2020)

We propose a feedforward active noise control (ANC) system with a coherence-adjusting filter. The feedforward ANC system can reduce the unwanted noise that is correlated with the reference signal picked up by the reference microphone. That is, the feedforward ANC system cannot reduce the unwanted noise when the unwanted noise and the reference signal are not correlated with each other. Hence, the coherence should be high to reduce the unwanted noise. However, only solution for the coherence problem is to place the reference microphone close to the error microphone. Under such a condition, the causality constraint is violated, and the noise reduction performance degrades. In this paper, we propose a feedforward ANC system with a coherence-adjusting filter that adjusts the reference signal to be similar to the unwanted noise. Then, the coherence between the reference signal and the unwanted noise increases, and the amount of noise reduction can be large even under the low-coherence condition. Simulation results show that the proposed ANC system can reduce the unwanted noise well compared with the conventional feedforward ANC system under different coherence conditions.
Which Threshold to Detect Hypoglycemia? (2001)

The Diabetes Control and Complications Trial (DCCT) showed that the improvement of glycemic control by intensive insulin therapy resulted in a decrease in the risk of late diabetic complications. However, this effect was associated with an increase (by a factor of 3) in the risk of severe hypoglycemia (1). This explains the interest in the development of a hypoglycemic alarm that uses continuous glucose monitoring. Several approaches to this are possible.

Noninvasive methods have the benefit of measuring glucose without breaking the cutaneous barrier. Generally, these methods are based on the principle of the analysis of the absorption of the light in a zone of the spectrum close to the infrared, or of the diffraction of the light in the skin. These two parameters are indeed influenced by the level of glycemia, but sensitivity and specificity of these methods are far from providing sufficiently useful miniaturized systems that can be used in clinical practice (2). In invasive methods, the system of measurement (or a part of the system of measurement) is placed inside the body. The system can be totally implantable, requiring that both the sensor and the electronic control system are miniaturized, which is currently possible. In addition, the system must work for a time period sufficiently long to avoid the need for frequent implantations. The sensitive part of the system (the sensor) may be placed directly into a blood vessel (3) or in subcutaneous tissue (4). Nevertheless, for obvious reasons, most of the invasive systems that have been developed so far use transcutaneous access.

Two basic approaches have been attempted. In the first approach, the glucose sensor has the shape of a needle that is implanted under the skin and is …

The crystal structure is the tetradymite with the (00l ) preferential orientation. Magnetoconductance data shows weak anti-localization phenomena at low temperatures. The presence of ferromagnetism is also demonstrating a strong anomalous Hall effect (AHE) and the sign of AHE resistances changes from negative to positive as the Mn concentration increases.
A design model applied to development of AmI systems (2006)

Abstract. Ambient intelligence (AmI) represents a promising paradigm for group-centred collaborative interaction with the surrounding environment. The complexity for AmI designs is closely connected with the mechanism for describing their inherent features. What would be interesting is a method which is capable of describing these properties in a straightforward way. Task modelling techniques are a suitable method for AmI systems. This paper describes a new design and implementation proposal for developing AmI systems, starting from the conceptual and methodological frameworks proposed by AMENITIES, a methodology based on task and behaviour models for the study and development of cooperative systems, extending it with inherent AmI features. With respect to the implementation of AmI systems, an intermediate software layer supporting common functional requirements is supplied in order to simplify their development. The overall scheme therefore simplifies the analysis and development of such systems. These features are shown in a case study of a collaborative e-learning AmI system. 1
Analysis of Coronary Arterial Dynamics from X-ray Angiographic Sequences (2009)

X-ray coronary angiography (CAG) is one of widely used imaging modalities for clinical diagnosis and interventional treatment of coronary artery diseases. CAG sequences covering one or several cardiac cycles record morphological as well as dynamic information of coronary arterial vessels and related myocardium during cardiac cycles. Detection of coronary arterial dynamic information from CAG sequences is one of important issues in post-processing CAG images. In this paper, two methods based on optical flow and elastic registration respectively are proposed to quantitatively estimate coronary arterial displacement fields from dynamic CAG sequences. Their performances are validated with clinical data and application scopes are analyzed.
Copper(II)-promoted solvolyses of nickel(II) complexes. III. Tetradentate Schiff base ligands containing various diamine segments (1973)

The large variations in the rates of the copper(II)-promoted solvolyses of various nickel(II) complexes, containing Schiff base ligands with varying diamine substituents, is attributed to steric effects. The important rate differences occur for reactants whose stereochemistries and electronic properties appear little different. However, the steric effects cannot be viewed definitely from either nickel-diamine dissociation or copper-diamine formation. Nickel reactants which may be distorted from planarity give trimeric products on reaction with copper in dmso and dmf, if the reactions are carried out at high initial concentration ratios of copper(II) to nickel complex. Ligand substitution studies indicate a differing reactivity sequence for the diamine-substituted ligands in their capacities as entering, compared to leaving, groups.
Protonation at the Aqueous Interface of Polymer Nanoparticles with Second Harmonic Generation (2008)

The protonation reaction of the carboxyl (−COOH) functional group fixed at the surface of polystyrene carboxylate (PSC) microspheres, with a radius of 457 ± 14 nm, dispersed in aqueous medium has been studied using the nonlinear optical method of second harmonic generation (SHG). We have demonstrated that the “χ(3) method,” along with the use of the Gouy−Chapman model describing the surface potential, can be used to determine the pKa of carboxyl groups at the particle−liquid interface. A surface pKa of 5.4 ± 0.3 has been determined for the PSC colloidal particles, which corresponds to a decrease in the acidity; that is, Ka is a factor of 4 smaller at the interface than that of long chain carboxyl acids in bulk aqueous solution.
Evolution of insulin-like growth factor binding proteins. (1993)

In order to understand more about the origins and evolutionary relationships of insulin-like growth factors (IGFs) and their binding proteins (IGFBPs) we have commenced characterization of the IGFBPs in non-mammalian sera. We show by both in vitro labelling with subsequent analytical gel filtration and by ligand blotting that IGFBPs are present in lamprey serum, indicating that the IGFBPs are indeed, very ancient proteins. Furthermore we present evidence that the major serum IGFBP in lamprey is significantly smaller than the high molecular weight IGFBP3 complex in rat serum. In addition, we show that IGFBPs occur widely throughout vertebrates as we detect IGFBPs in ligand blots of serum from marsupials, monotremes, reptiles, birds and turtles.
Isolation and Culture of Porcine Hepatocytes for Artificial Liver Support (1996)

The primary requirement of cells in a liver support system is the preservation of the in vivo metabolic functions that prevent or decrease the progress of hepatic encephalopathy (HE) by providing interim support to liver failure patients. While rodent hepatocytes offer a model for liver assist device (LAD) research, their limited number per animal prohibits direct scale up to human devices. Healthy human liver cells are seldom available in adequate numbers to support clinical LAD use; consequently, a large animal source of liver cells is needed. The study presented here explored the potential of porcine hepatocytes to proliferate and maintain metabolic function in vitro. Porcine hepatocytes were isolated from ~12 kg swine by a modification of Seglen's method. Hepatocytes cultured up to 10 days were shown to metabolize ammonia and maintain both Phase I and II detoxification functions. In addition, the cultures showed proliferative activity both as an increase in total protein content and by thymidine incorporation. Immunocytochemical staining identified cell proliferation through Day 4 to be primarily hepatocytes while Days 6 and 10 showed nonparenchymal cells to be increasing. The detoxification functions measured showed peak activity on Day 4 and gradually declined through Day 10. The ability of porcine hepatocytes to proliferate and maintain a diversity of hepatic functions in culture strongly suggests their potential for use as the biological component of artificial LADs.
Water-Soluble Narrow-Line Radicals for Dynamic Nuclear Polarization (2012)

The synthesis of air-stable, highly water-soluble organic radicals containing a 1,3-bis(diphenylene)-2-phenylallyl (BDPA) core is reported. A sulfonated derivative, SA-BDPA, retains the narrow electron paramagnetic resonance linewidth (<30 MHz at 5 T) of the parent BDPA in highly concentrated glycerol/water solutions (40 mM), which enables its use as polarizing agent for solid effect dynamic nuclear polarization (SE DNP). A sensitivity enhancement of 110 was obtained in high-field magic-angle-spinning (MAS) NMR experiments. The ease of synthesis and high maximum enhancements obtained with the BDPA-based radicals constitute a major advance over the trityl-type narrow-line polarization agents.

Population Genomics Reveals Low Genetic Diversity and Adaptation to Hypoxia in Snub-Nosed Monkeys (2016)

Snub-nosed monkeys (genus Rhinopithecus) are a group of endangered colobines endemic to South Asia. Here, we re-sequenced the whole genomes of 38 snub-nosed monkeys representing four species within this genus. By conducting population genomic analyses, we observed a similar load of deleterious variation in snub-nosed monkeys living in both smaller and larger populations and found that genomic diversity was lower than that reported in other primates. Reconstruction of Rhinopithecus evolutionary history suggested that episodes of climatic variation over the past 2 million years, associated with glacial advances and retreats and population isolation, have shaped snub-nosed monkey demography and evolution. We further identified several hypoxia-related genes under selection in R. bieti (black snub-nosed monkey), a species that exploits habitats higher than any other nonhuman primate. These results provide the first detailed and comprehensive genomic insights into genetic diversity, demography, genetic burden, and adaptation in this radiation of endangered primates.
Plasmodium vivax: isolation of mature asexual stages and gametocytes from infected human blood by colloidal silica (Percoll) gradient centrifugation (1987)

The densities of human erythrocytes infected with P. vivax obtained from infected patients were determined by isopycnic centrifugation in continuous gradients of Percoll. The approximate densities of erythrocytes infected with rings were 1.086 to 1.1, trophozoites (amoeboid stages) 1.053 to 1.086, schizonts and gametocytes 1.053 to 1.056 and of the other cellular elements of blood, uninfected erythrocytes, 1.086 to 1.1, polymorphonuclear leucocytes 1.073 to 1.086 and mononuclear cells 1.062 to 1.073 g/ml. Based on these values, a one-step gradient of 47% Percoll was devised to separate erythrocytes infected with the more mature stages (trophozoites, schizonts and gametocytes) from uninfected erythrocytes. By this method it is possible to obtain parasitaemias of 88% to 98% from blood with starting parasitaemias of less than 0.7%. This method is therefore being routinely used for immunological, biochemical and molecular biological studies on P. vivax.
Highly Efficient and Mild Cascade Reactions Triggered by Bis(triphenyl)oxodiphosphonium Trifluoromethanesulfonate and a Concise Total Synthesis of Camptothecin (2007)

A mild and efficient cascade methodology is reported to construct variously substituted indolizino[1,2-b]quinolin-9(11H)-ones. Efficiently triggered by bis(triphenyl)oxodiphosphonium trifluoromethanesulfonate under mild conditions, this cascade achieved significant enhancements in chemical yields. Utilizing this highly efficient domino reaction followed by a Sharpless dihydroxylation, an eight-step total synthesis of camptothecin was accomplished from a known pyridine derivative in direct fashion with an overall yield of 47% and 95% ee.
Singlet Sensitization-Enhanced Upconversion Solar Cells via Self-Assembled Trilayers (2019)

Photon upconversion via triplet–triplet annihilation (TTA-UC) is a promising strategy for increasing maximum theoretical solar cell efficiencies by a factor of 1.3. However, one factor limiting integrated TTA-UC solar cell performance is the transmission window between sensitizer and acceptor molecule absorption. Here we demonstrate that the incorporation of a singlet sensitizer (SS) into a self-assembled trilayer is an effective means of harnessing that previously transmitted light. A record TTA-UC photocurrent density of 0.315 mA cm–2 under 1 sun irradiation was achieved and is attributed to directional SS-to-sensitizer singlet energy transfer and sensitizer-to-acceptor triplet energy transfer, followed by TTA, excited-state electron transfer into TiO2, and regeneration by a redox mediator in solution. These results demonstrate that singlet sensitization-enhanced self-assembled trilayers are a promising strategy for enhancing broad-band light absorption and improving the performance of TTA-UC solar cells.
Kickstarting Deep Reinforcement Learning (2018)

We present a method for using previously-trained 'teacher' agents to kickstart the training of a new 'student' agent. To this end, we leverage ideas from policy distillation and population based training. Our method places no constraints on the architecture of the teacher or student agents, and it regulates itself to allow the students to surpass their teachers in performance. We show that, on a challenging and computationally-intensive multi-task benchmark (DMLab-30), kickstarted training improves the data efficiency of new agents, making it significantly easier to iterate on their design. We also show that the same kickstarting pipeline can allow a single student agent to leverage multiple 'expert' teachers which specialize on individual tasks. In this setting kickstarting yields surprisingly large gains, with the kickstarted agent matching the performance of an agent trained from scratch in almost 10x fewer steps, and surpassing its final performance by 42 percent. Kickstarting is conceptually simple and can easily be incorporated into reinforcement learning experiments.
Unexpected height offsets in TanDEM-X: Explanation and correction (2012)

This paper reports on systematic height offsets that have been observed in TanDEM-X by evaluating a large number of digital elevation model (DEM) acquisitions. Besides the expected instrument and baseline offsets, which are compensated in the calibration chain, two unexpected external error sources have been identified that apply to any formation flying bistatic SAR interferometer. The first contribution is due to relativistic effects and can be well explained within Einstein's special theory of relativity. The second effect is due to differential delays in the troposphere. It is shown that the theoretic predictions are in good agreement with the observed offsets. All necessary corrections have in the meantime been integrated in the operational TanDEM-X processing chain.

Properly piled up: Single-layer 2D semiconducting nanomaterials of MoS2, WS2, TiS2, TaS2, ZrS2, and graphene were fabricated through an electrochemical lithiation process (see picture). The production of single-layer MoS2 was achieved in 92 % yield. A single-layer MoS2-based thin-film transistor was fabricated, which was used for sensing NO at a detection limit of 190 ppt.
Breaking Olympic records (1996)

Reading the records of the 19th century may be a pleasant pastime for today's athletes; if a hundred years ago you could have run, for example, 10 000 metres in 30 minutes, you would have been a world champion. Will athletes in another 100 years look back to present day records with the same envy? Plotting the running speeds of the record holders for 200 m, 1500 m, and the marathon (42.2 km) shows a linear increase with time from the early 1900s to today, with no evidence of an approach to a plateau.1 Indeed, Whipp and Ward have shown that women are currently improving at a faster rate than men.2 If this rate of improvement is maintained, there will come a time when the best women will beat the best men. The authors predict that this could occur around the year 2035 for most events, and much sooner in the marathon. However, …
German Aortic Valve Score: a new scoring system for prediction of mortality related to aortic valve procedures in adults (2013)

It is well known that a predictive model works best in the setting where it was developed; therefore, the German AV Score fits well to the patient population in Germany. It was designed for fair and reliable outcome evaluation. It allows comparison of predicted and observed mortality for conventional aortic valve surgery and transcatheter aortic valve implantation in low-, moderate- and high-risk groups. Thus, it enables primarily a risk-adjusted benchmark of outcome and fosters the efforts for continuous improvement of quality in aortic valve procedures.
Additive Fertigung keramischer Komponenten: Grundlagen und Anwendung (2020)

Unter dem Begriff „Additive Fertigung“ werden alle Verfahren zusammengefasst, die dazu dienen Formteile aufgrund von CAD-Daten schichtweise aufzubauen. Dabei geschieht der Aufbau stets selektiv, entsprechend der durch die CAD-Daten vorgegebenen Positionen. Während für Metalle und Kunststoffe diese Technik bereits in der industriellen Anwendung etabliert ist, befindet sie sich im Bereich der keramischen Werkstoffe noch in einer frühen Entwicklungs- bzw. Anwendungsphase. Um so wichtiger ist es, den aktuellen Stand der Technik und das Potenzial für keramische Bauteile umfassend darzustellen.
Circuit Formation on the Smooth Glass Substrate by a Semi-Additive Process (2017)

Circuit formation by a semi-additive process of copper films on glass was investigated. Copper films were produced on a glass substrate by direct electroless copper plating on a 20-30-nm-thick copper inclusive titanium oxide catalytic adhesion layer formed earlier on the glass substrate surface using a sol-gel method. After seed layer deposition, galvanic deposition thickened the copper film to 10 μm. Formation of L / S ＝ 50/50 μm to 200/200 μm copper circuit patterns on the glass substrate was then demonstrated, where adhesion was maintained throughout the process. The copper-inclusive titanium oxide adhesion layer was removed completely from the glass substrate surface without notably altering the glass surface morphology using a sodium hydroxide 100 g / L, trisodium citrate 5 g / L solution etching solution. Furthermore, in post electroless Ni-P plating, extraneous deposition was prevented by complete removal of the titanium oxide adhesion layer.
10Gb/s receiver with track-and-hold-type linear phase detector and charge-redistribution 1<sup>st</sup>-order &#x0394;&#x03A3; modulator (2009)

A 10 Gb/s receiver, which is equipped with a track-and-hold-type linear phase detectors (LPD) as well as charge redistribution DeltaSigma modulator for incorporation in a digital clock and data recovery (CDR), is described. The 10 Gb/s receiver exhibited low quantization errors and high loop bandwidth that are due to the use of LPD while it maintains the advantages of a digital CDR circuit such as low power consumption, small area occupation, fast locking time, and low-jitter recovered clock. Results also reveal that the tracking bandwidth of the CDR circuit is about 20 MHz, and the power consumption of the receiver is 65 mW.
Sitagliptin Reduces Inflammation and Chronic Immune Cell Activation in HIV+ Adults With Impaired Glucose Tolerance (2015)

Sitagliptin had beneficial systemic and adipose anti-inflammatory effects in cART-treated HIV+ adults with impaired glucose tolerance. Large-scale, long-term studies should determine whether sitagliptin reduces cardiovascular risk and events in HIV+ adults.
