Delay oriented design methodology: application to the design of a VHF low power VLSI polyphase oscillator (2002)

A new design methodology (Delay Oriented Design-DOD) has been developed in order to design a novel oscillator architecture. A 250 MHz DOD oscillator has been implemented on a 0.8 /spl mu/m, two metal layers standard VLSI CMOS technology. It provides both in-phase and quadrature-phase differential outputs on a 60 MHz frequency range. The measured phase noise at 1 kHz offset from the carrier is about -92 dBc/Hz. The oscillator current consumption is 3 mA on a 3.3 V voltage supply.
Phase equilibria of quasi‐binary systems consisting of multicomponent polymers 1 and 2. III—Coexistence curve (1992)

Abstract As an extension of the theory established previously ( Brit. Polym. J. , 23 (1990) 285 and 299), a method for calculating the coexistence curve (CC) was proposed for multicomponent polymer 1/multicomponent polymer 2 system. The polymer composition, molecular weight distribution existing in two liquid phases and their phase volume ratio (R) can be calculated for the systems of polymer whose molecular weight characteristics and the initial composition are known in advance. Systematic computer experiments were carried out to disclose the effect of the average degree of polymerization (DP), the DP distribution of two polymers and the initial concentration on phase diagram including CC. The polydispersity of the polymers can not be ignored in CC as in the case of the cloud point curve (CPC) and the critical solution point (CSP). In the vicinity of CPC, the two‐phase volume ratio changes dramatically corresponding to a slight change in the thermodynamical interaction parameter X 12 between polymers 1 and 2. As the initial polymer concentration approaches CSP, R approaches unity and DP distributions of polymers partitioned in two phases reduce to that of the original polymers.

Separation of Europium from other Rare Earths by the “Oxine‐Sulfonic Acid Method” (1956)

Abstract A mixed ammoniacal solution of oxine‐sulfonic acid, samarium, europium and a small amount of gadolinium nitrate was electrolytically reduced using a platinum cathode in the presence of acetic acid. Europium was quantitatively precipitated with very little samarium (estimated at‐1 or 2%). The other earths remaind in solution. The greenish yellow precipitate corresponded to the formula, H 2 (Eu‐(C 9 H 5 NOSO 3 ) 2 )·4H 2 O.
Optical millimeter-wave generation and wireless data transmission using a dual-mode laser (2000)

A dual-mode self-pulsating laser is presented as a transmitter source for millimeter wave generation in an experimental hybrid fiber radio system. The performance is evaluated by bit-error rate measurements in the 40-GHz-frequency range including a radio link and a fiber based transmission with lengths up to 60 km.
Purification and properties of the RecR protein from Bacillus subtilis 168. (1993)

Genetic evidence suggests that the Bacillus subtilis recR gene product is involved in DNA repair and recombination. To assign a biochemical function to the recR gene product, the RecR protein was labeled and purified by monitoring the radioactive label. NH2-terminal protein sequence analysis of RecR was consistent with the deduced amino acid sequence of the recR gene. The RecR protein (molecular mass of 25 kDa, isoelectric point 5.4) bound single- and double-stranded DNA in a filter binding assay. RecR-DNA complex formation is enhanced by the presence of a damage in the DNA substrate. The RecR-DNA complex formation proceeds in the absence of divalent cations and nucleotide cofactors, but is markedly stimulated by ATP and divalent cations. In our experimental conditions the apparent equilibrium constants of the optimized RecR-DNA complexes are 3 x 10(-7) M and 9 x 10(-7) M for damaged and undamaged DNA, respectively. The binding reaction is cooperative. Electron microscopy studies show that the presence of divalent cations increases the rate of RecR protein self-assembly. Addition of ATP or dATP promotes the organization of discrete series of quaternary structures on DNA, but ATP gamma S inhibits the DNA binding activity. A possible mechanism for the RecR function in DNA repair is discussed.
DNA Polymorphism Analysis as a New Program in the Basic Medical Experiment Course (2008)

A new program, analysis of single nucleotide polymorphism (SNP), started in the Basic Medical Experiment Course for 3rd grade students of Nihon University School of Medicine. After hearing lectures about SNP, polymerase chain reac-tion (PCR), and ethical rules regarding human samples, students extracted DNA from their own saliva and examined SNPs for aldehyde dehydrogenase 2 (ALDH2) and actinin 3 (ACTN3) genes with allele-specific amplification PCR and TaqMan SNP genotyping PCR, respectively. ALDH2 is involved in ethanol metabolism and its SNP is associated with ethanol tolerance. ACTN3 is an actin-binding protein in skeletal muscles and its SNP is differently associated with sprint and endurance athletes at the Olympic level. Students discussed their genotypes and the reported phenotypes with great interest. The application of a new molecular biology technique in medical science during a student experiment program could have great educational effects on medical students.

Configuring IPv4 over IPv6 Networks: Transitioning with DHCP (2014)

To transition to IPv6, ISPs must determine how to configure IPv4 over IPv6 networks using the Dynamic Host Configuration Protocol (DHCP). However, multifarious requirements result in various solutions. The authors sort out the requirements for configuring an IPv4 node in IPv6 networks, survey IETF standardization efforts, and give recommendations on this topic.
Recurrent herpes simplex labialis: selected therapeutic options. (2003)

Recurrent infection with herpes simplex virus 1 (HSV1), called herpes simplex labialis (HSL), is a global problem for patients with normal immune systems. An effective management program is needed for those with frequent HSL recurrences, particularly if associated morbidity and life-threatening factors are present and the patient's immune status is altered. Over the past 20 years, a variety of antiviral compounds (acyclovir, penciclovir, famciclovir, valacyclovir) have been introduced that may reduce healing time, lesion size and associated pain. Classical lesions are preceded by a prodrome, but others appear without warning, which makes them more difficult to treat. Various methods of application (intravenous, oral, topical) are used, depending on whether the patient is experiencing recurrent HSL infection or erythema multiforme or is scheduled to undergo a dental procedure, a surgical procedure or a dermatological face peel (the latter being known triggers for recurrence). This article outlines preferred treatment (including drugs and their modes of application) for adults and children in each situation, which should assist practitioners wishing to use antiviral therapy.

Porphyrin−Perylene Bisimide Dyads and Triads:  Synthesis and Optical and Coordination Properties (2004)

[structure: see text] Novel porphyrin perylene dyad and triad dyes have been prepared by the coupling of aminophenyltrisphenylporphyrin and tetraphenoxy-substituted perylenetetracarboxylic acid bisanhydrides in a one-step synthesis. Fluorescence spectra of these compounds reveal features that are attributable to emission of perylene bisimides as well as porphyrin excited states. The self-assembly behavior of zinc-metalated compounds with 4,4'-bipyridine and diazabenzoperylene has been investigated by (1)H NMR spectroscopy in CDCl(3), showing that oligomeric zigzag assemblies are formed.

Pedestrian Tracking and Stereo Matching of Tracklets for Autonomous Vehicles (2019)

The prediction of the surrounding pedestrians' walking paths is a vital part for autonomous driving systems in the aspect of traffic safety. In this paper, we propose a pipeline which tracks pedestrians captured by a stereo camera system onboard a mobile vehicle, composes the pedestrian tracklets, clusters the tracklets to form trajectories, and matches the trajectories. The output 3D pedestrian trajectories can be used for further applications such as pedestrian trajectory prediction for driverless vehicles. Our algorithm has been compared with various state-of-art pedestrian tracking methods. Our experimental results show that the visual temporal features computed by our algorithm are effective for trajectory representation and that, by incorporating tracklet clustering into the pipeline, the pedestrian tracking performance is improved.
Deep learning of quantum entanglement from incomplete measurements (2023)

The quantification of the entanglement present in a physical system is of paramount importance for fundamental research and many cutting-edge applications. Now, achieving this goal requires either a priori knowledge on the system or very demanding experimental procedures such as full state tomography or collective measurements. Here, we demonstrate that, by using neural networks, we can quantify the degree of entanglement without the need to know the full description of the quantum state. Our method allows for direct quantification of the quantum correlations using an incomplete set of local measurements. Despite using undersampled measurements, we achieve a quantification error of up to an order of magnitude lower than the state-of-the-art quantum tomography. Furthermore, we achieve this result using networks trained using exclusively simulated data. Last, we derive a method based on a convolutional network input that can accept data from various measurement scenarios and perform, to some extent, independently of the measurement device.
Monitoring phytoplankton and marine biotoxins in production waters of the Netherlands: results after one decade (2011)

Shellfish products may be contaminated with marine biotoxins which, after consumption, may lead to human illness. The Netherlands has a regular monitoring programme for marine biotoxins and the possible toxic phytoplankton in shellfish production waters. The aim of the current study was to evaluate the presence of potential toxic phytoplankton species and marine biotoxins in Dutch production waters over the last decade, and to analyse the relationship between toxin levels and abundance of possible causative phytoplankton species. The results of the monitoring programme of the period 1999-2009 were used. The presence of Alexandrium spp. were negligible, but Pseudo-nitzschia spp. and phytoplankton causing diarrhetic shellfish poisoning (DSP toxin-producing phytoplankton) were present in nearly all three main production areas and years. The main DSP toxin-producing species was Dinophysis acuminata followed by D. rotundata and Prorocentrum lima. Toxins causing paralytic shellfish poisoning (PSP) and amnesic shellfish poisoning (ASP) were present in only a few individual shellfish samples, all at low levels. At the end of 2002, an episode of DSP toxicity was recorded, based on the rat bioassay results. Of the samples that were chemically analysed for DSP toxins in 2007 and 2008, about half of the samples in 2007 contained these toxins, although levels were low and no positive results were obtained using the rat bioassay. There was a slight positive correlation between concentrations of DSP toxin-producing phytoplankton and levels of DSP toxins in 2007. Increased DSP toxin levels were found up to 5 weeks after the peak in DSP toxin-producing phytoplankton. This positive, but weak, relationship needs to be confirmed in future research using more samples and chemical methods to quantify the presence of DSP toxins. If this relationship is further substantiated and quantified, it could be used within the current monitoring programme in the Netherlands to predict the risk areas regarding DSP toxicity in shellfish.
Efficient block-based intra prediction for image coding with 2D geometrical manipulations (2008)

A novel block-based intra-prediction scheme is proposed for efficient image (or intra-frame) coding, where we apply various 2D geometrical manipulations to reference image blocks to enrich the pool of prediction blocks for a given target block. As compared with the traditional line-based intra prediction in H.264/AVC, the new scheme offers a significant coding gain (about 0.24∓1.23dB in the PSNR value with the same bit rate) at the cost of higher complexity. Several techniques to reduce the search complexity are also discussed.
The BNT162b2 mRNA Vaccine Elicits Robust Humoral and Cellular Immune Responses in People Living With Human Immunodeficiency Virus (HIV) (2021)

Previous studies have shown that certain vaccines induce suboptimal responses in people living with human immunodeficiency virus (HIV, PLWH). However, responses to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccines have not been fully characterized in these patients. Here we show that the BNT162b2 vaccine induces robust immune responses comparable to responses in healthy donors.
Dielectric and Piezoelectric Properties of (Bi0.5Na0.5)TiO3–(Bi0.5K0.5)TiO3 Systems (1999)

The structural, dielectric and piezoelectric properties of [Bi 0.5 (Na 1- X K X ) 0.5 ]TiO 3 ceramics were studied for the compositional range, X =0–1.0. The samples were prepared by a conventional sintering technique. From X-ray diffraction results, it was found that the morphotropic phase boundary (MPB) between (Bi 0.5 Na 0.5 )TiO 3 (rhombohedral) and (Bi 0.5 K 0.5 )TiO 3 (tetragonal) exists in the range of X =0.16–0.20. Polarization-Electric field hysteresis loops show that the remanent polarization at X =0.20 (BNTK20) is larger than that at X =0.0 (BNT). Peaks of electromechanical coupling factor, dielectric constant, piezoelectric constant and elastic compliance were obtained at X =0.16–0.20 of the MPB region. Dielectric and piezoelectric properties are enhanced in the MPB region for [Bi 0.5 (Na 1- X K X ) 0.5 ]TiO 3 , similar to that observed for Pb(Zr, Ti)O 3 .

Kinematic simulation of turbulent dispersion of triangles (2003)

As three particles are advected by a turbulent flow, they separate from each other and develop nontrivial geometries, which effectively reflect the structure of the turbulence. We investigate here the geometry, in a statistical sense, of three Lagrangian particles advected, in two dimensions, by kinematic simulation (KS). KS is a Lagrangian model of turbulent diffusion that makes no use of any delta correlation in time at any level. With this approach, situations with a very large range of inertial scales and varying persistence of spatial flow structure can be studied. We first demonstrate that the model flow reproduces recent experimental results at low Reynolds numbers. The statistical properties of the shape distribution at a much higher Reynolds number is then considered. The numerical results support the existence of nontrivial shape statistics, with a high probability of having elongated triangles. Even at the highest available inertial range of scales, corresponding to a ratio between large and small scale L/eta=17,000, a perfect self-similar regime is not found. The effects of the parameters of the synthetic flow, such as the exponent of the spectrum and the effect of the sweeping affect our results, are also discussed. Special attention is given to the effects of persistence of spatial flow structure.
Volume and duration of losses in finite buffer fluid queues (2015)

We study congestion periods in a finite fluid buffer when the net input rate depends upon a recurrent Markov process; congestion occurs when the buffer content is equal to the buffer capacity. Similarly to O'Reilly and Palmowski (2013), we consider the duration of congestion periods as well as the associated volume of lost information. While these quantities are characterized by their Laplace transforms in that paper, we presently derive their distributions in a typical stationary busy period of the buffer. Our goal is to compute the exact expression of the loss probability in the system, which is usually approximated by the probability that the occupancy of the infinite buffer is greater than the buffer capacity under consideration. Moreover, by using general results of the theory of Markovian arrival processes, we show that the duration of congestion and the volume of lost information have phase-type distributions.
Implications of the 2021 CKD-EPI cystatin C/creatinine eGFR equation for eligibility for therapy in HFrEF: insights from PARADIGM-HF (2022)

Abstract Background Estimated glomerular filtration rate (eGFR) is a key determinant of eligibility for many life-saving therapies in HFrEF. Recently, the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) provided new equations based on creatinine (CKD-EPIcr), cystatin C (CKD-EPIcys) or both (CKD-EPIcyscr) that do not include race. These new equations may reclassify individuals, irrespective of race, from one eGFR category to another, with implications for eligibility for HFrEF treatments. Purpose To assess the difference between eGFR estimation using the 2021 CKD-EPIcyscr equation and the 2009 CKD-EPIcr and Modification of Diet in Renal Disease Study (MDRD)-4 equations which are still standard in many European laboratories. Methods We included patients from PARADIGM-HF with cystatin C and creatinine values available at the time of randomization. For each patient, baseline eGFRs were calculated using the 3 equations described. Our focus was on patients with chronic kidney disease (CKD) stages III–V. Results Overall, 1910 patients were eligible. Mean age was 67.3 (10.1) year and 385 (18.7%) were female. Using 2009 CKD-EPIcr, 779 patients were in CKD stages 3–5, of which 233 (30%) were reclassified to a better CKD stage (higher eGFR) with the 2021 CKD-EPIcyscr equation (Table 1). Similar reclassification was seen when comparing MDRD-4 with the 2021 CKD-EPIcyscr equation: 277 (33%) of 831 patients in CKD stages 3–5 were reclassified to a better CKD stage (Figure 1). Conclusions The 2021 CKD-EPIcyscr equation favourably reclassified CKD stage in a large percentage of patients with HFrEF and a low eGFR, potentially increasing the proportion of these patients considered eligible for guideline-recommended therapies.

Acoustic echo cancellation for hands-free telephony using neural networks (2002)

One of the limitations of linear adaptive echo cancellers in hands-free environments is their inability to effectively cancel nonlinearities which are generated mainly in the loudspeaker during large signal peaks. The soft-clipping effect encountered when large signals are applied to the loudspeaker is modelled in a neural network using a piecewise linear/sigmoid activation function. A three-layer fully adaptive feedforward network is used to model the room/speakerphone transfer function using the special activation function. This network structure improves the ERLE performance by 10 dB at low to medium loudspeaker volumes compared to a NLMS echo canceller.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
A prime factor FTT algorithm using distributed arithmetic (1982)

A time-efficient algorithm for calculating the discrete Fourier transform is developed. It uses a prime factor decomposition of the DFT into multiple short prime length DFT's which are converted into cyclic convolutions by an index permutation based on number theory. The convolutions are evaluated by table look-up using distributed arithmetic. When programmed on a Z80 microprocessor, the algorithm is 2-20 times faster than conventional algorithms. The approach also makes it possible to add simple external logic to a micro-processor system to further increase the speed.
