Characterization of Aligned Wafer-Level Transfer of Thin and Flexible Parylene Membranes (2007)

This paper reports a wafer-level transfer technique for forming thin, flexible, and freestanding parylene membranes. Parylene thin films (~1.3 mum) have been successfully transferred from one wafer to another to form a freestanding membrane encapsulating over wide and shallow cavities (< 5 mum deep and 2000 times 2000 mum <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> square) with fine alignment (< 3.0 mum) and 87% yield. Transferred membranes may be a composite of parylene/metal/parylene, contain through-hole patterns of diverse size (5 times 5 ~ 2000 times 2000 mum <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> ), have mild tension (1.14 MPa), and remain freestanding and flat through various standard post-transfer microfabrication processes such as photolithography, evaporation, and wet etching. They also provide excellent sealing against pressure of up to 20 kPa and long-term stability over repeated deflection. This paper focuses on two areas: (1) the study of issues involving optimum transfer conditions, minimum achievable gap between transferred membranes and device wafers, patterned-film and composite-layer transfer, and aligned transfer; and (2) the characterization of the post-transfer membrane properties, including stress/tension, sealing capability, effects of post-transfer processing, and long-term stability after a repeated deflection.
Germination of Witchweed ( Striga lutea Lour.): Isolation and Properties of a Potent Stimulant (1966)

A crystalline germination stimulant (trivial name strigol) for the rootparasite, witchweed (Striga lutea Lour.), has been isolated from cotton rootexudates and characterized as a C(19)H(22)O(6) compound. Although apparently different from known plant hormones, the stimulant is active at hormonal levels, causing germination at concentrations less than 1O(-5) part per million.

The isolation of cDNA clones from cucumber (Cucumis sativus L.) floral buds coming from plants differing in sex. (2003)

In this study, we found flower cDNA clones which may be connected with the development of flower sex in cucumber. Two pairs of nearly-isogenic lines: gynoecious GY3 (FFMMGG) versus hermaphrodite HGY3 (FFmmGG) and monoecious B10 (ffMMGG) versus gynoecious 2gg (ffMMgg) were used for clone isolation. To obtain differentially-expressed clones, we applied the differential screening method. 454 clones from GY3 and 478 from B10 cDNA libraries were isolated. The results of RFLP analysis with 56 cDNA clones showed no clones which cosegregated with sex in cucumber. The 28 cDNA B10 and 33 cDNA GY3 clones isolated using the differential screening method were sequenced. Some of them seem to may play a role in cell differentiation or flower development. Among the 61 identified clones, 14 show high homology to plant proteins, although of unknown function. 11 show high homology to known proteins, and the possible function of some of them is discussed. For 3 clones, no significant similarity was found. The 31 clones displayed high homology to plant cDNA in EST database. The patterns of expression of five differential cDNA clones, 35GY3, 216GY3, 47GY3, 100B10 and 157B10, were analyzed in cucumber flower buds using in situ RT-PCR. The most interesting clone is 35GY3, because of its possible role in the inhibition of the development of male specific elements in the female cucumber flower.
Equivalent wave field of diffusive controlled source electromagnetic (CSEM) data (2019)

We investigate two approaches to the transformation of CSEM data to a more readily interpretable wave field. The first describes the CSEM response as a weighted sum of wave-like Chebyshev polynomials; it requires the inversion of a matrix. The second describes the diffusion response as a convolution of the equivalent wavefield with a filter in log(time) and requires deconvolution. The second appears to be more robust and gives good results for test data.

Robust quantum-network memory based on spin qubits in isotopically engineered diamond (2022)

Abstract Quantum networks can enable quantum communication and modular quantum computation. A powerful approach is to use multi-qubit nodes that provide quantum memory and computational power. Nuclear spins associated with defects in diamond are promising qubits for this role. However, dephasing during optical entanglement distribution hinders scaling to larger systems. Here, we show that a 13 C-spin quantum memory in isotopically engineered diamond is robust to the optical link operation of a nitrogen-vacancy centre. The memory lifetime is improved by two orders-of-magnitude upon the state-of-the-art, surpassing reported times for entanglement distribution. Additionally, we demonstrate that the nuclear-spin state can survive ionisation and recapture of the nitrogen-vacancy electron. Finally, we use simulations to show that combining this memory with previously demonstrated entanglement links and gates can enable key network primitives, such as deterministic non-local two-qubit gates, paving the way for test-bed quantum networks capable of investigating complex algorithms and error correction.

Advanced oxidation and artificial recharge: a synergistic hybrid system for removal of organic micropollutants (2009)

Dunea, the drinking water company for The Hague and surroundings, has as objective the production of drinking water of impeccable quality, particularly with respect to organic micropollutants. As organic micropollutants are only a minor part of the total natural organic matter, a challenge is posed in targeting the removal of a very small, specific part of the DOC, without removing all of the natural organic matter. In addition, organic micropollutants encompass a broad range of physicochemical properties, which make their removal by a single treatment step impossible. Combining AOP with artificial recharge and recovery, two complementary processes are expected to provide a hybrid system for organic micropollutant removal, according to the Dutch multiple barrier approach. Pilot-scale experiments with O3 and different advanced oxidation processes (UV/H2O2, UV/O3 and O3/H2O2) were carried out in cooperation between Dunea and ITT Wedeco. The pilot installation had a capacity of about 0.5–2.0 m3/h, with a varying LP-UV-dose, ozone dose and peroxide dose. Atrazine, isoproturone, carbamazepine, diclofenac and ibuprofen are well removed by UV/H2O2 as well as by O3/H2O2. In general, O3/H2O2 is a more energy efficient process compared to UV/H2O2. MTBE is best removed by O3/H2O2, Amidotrizoic acid and iohexol are best removed by UV/H2O2.
The role of mycoplasmas, ureaplasmas and chlamydiae in the genital tract of women presenting in spontaneous early preterm labour (1987)

The genital carriage of Ureaplasma urealyticum, Mycoplasma hominis and Chlamydia trachomatis was assessed in 72 women admitted to hospital in spontaneous preterm labour and in 26 women requiring preterm delivery for other reasons who formed a control group. Women in preterm labour significantly more often carried ureaplasmas, had large numbers of M. hominis and subsequently developed chorioamnionitis than women in the control group. M. hominis, in particular, occurred more frequently and in large numbers in women who had chorioamnionitis associated with ruptured membranes. Genital carriage of the various micro-organisms appeared not to be associated with fetal growth retardation, although subsequent isolation of ureaplasmas from infants was common. It is suggested that mid-second-trimester vaginal specimens should be cultured on a research basis to establish whether these various micro-organisms identify women at risk of labouring preterm.
Theoretical Analysis and Numerical Simulation of a High Power Helical Array Antenna Fed from Double-Layer Radial Waveguide (2005)

This paper describes a new antenna to realize the directional radiation of high-power microwave-helical array antenna fed from double-layer radial waveguide.The feed wire of each helix is connected with an H-coupled probe inserted into a radial waveguide,and excited by a TEM wave between the two parallel plates of the waveguide.Helices and probes are arranged on the upper plate to form a circular array.This antenna accepts directly an azimuthally symmetric output of a HPM source and radiates a high-gain pattern with a boresight peak.The use of H-coupled probes makes the array antenna compatible with the intense electric fields associated with high-power microwave sources.In addition,the array antenna has a simple structure and can project circular polarized electric field.In this paper,the fundamental theory of function is presented;an array antenna for a frequency band of 3.8GHz to 4.2GHz is designed and simulated.At 4.0GHz,the calculated aperture efficiency shows a high value of 72.3% and the axial ratio value at the normal direction is of 1.55.In the range of 3.8GHz to 4.2GHz,the aperture efficiency is over 69% and the axial ratio is below 1.7.
Corrigendum: Developmental regulation of cell type-specific transcription by novel promoter-proximal sequence elements (2020)

In the above-mentioned article, it has come to the authors' attention that the CNAAATT motif was originally discovered in the 5 UTR of the Mst87F gene as the translational control element (TCE) In these published works, the motif was shown to be important for testis-specific expression of these genes through careful experimental and computational analysis.
Antibacterial and anti-inflammatory effects of Jeju medicinal plants against acne-inducing bacteria (2008)

Propionibacterium acnes and Staphylococcus epidermidis are pus-forming bacteria that trigger inflammation in acne. The present study was conducted to evaluate the antimicrobial activities of Jeju medicinal plants against these etiologic agents of acne vulgaris. Ethanol extracts of Jeju plants were tested for antimicrobial activities by disc diffusion and broth dilution methods. The results from the disc diffusion assays revealed that four medicinal plants, Mollugo pentaphylla, Angelica anomala, Matteuccia orientalis, and Orixa japonica inhibited the growth of both pathogens. Among these, A. anomala had strong inhibitory effects. Its MIC values were 15.6 microg/ml and 125 microg/ml against P. acnes and S. epidermidis, respectively. The cytotoxic effects of the four extracts were determined by colorimetric MTT assays using two animal cell lines: human dermal fibroblasts and HaCaT cells. Although the M. orientalis root extract had moderate cytotoxicity in HaCaT cells at 200 microg/ml, most extracts exhibited low cytotoxicity at 200 microg/ml in both cell lines. In addition, the extracts reduced the P. acnes-induced secretion of interleukin-8 and tumor necrosis factor-alpha (TNF-alpha) in THP-1 cells, an indication of their anti-inflammatory effects. Based on these results, we suggest that M. pentaphylla, A. anomala, M. orientalis, and O. japonica are attractive acne-mitigating candidates for topical application.
Quantitative Modeling of Magnetosphere-Ionosphere Coupling Processes (1988)

This paper reviews the topical conference named above, which was held in Kyoto, March 9-13, 1987. With a well organized program of excellent papers, the symposium celebrated a right of passage in the life of our discipline. After growing in stages from a largely qualitative discipline divided into distinct, mostly non-communicating compartments, the field enters the fourth decade of the space age a largely quantitative, communicating, integrated discipline. The aspect most indicating achieved maturity is the shared view that the solar wind-magnetosphere-ionosphere system is an interactively coupled unit, which might be called the geospace system, whose properties must be determine through discipline-wide cooperative research. In the area of theory, the geospace system's great complexity and the drive to understand it quantitatively put great emphasis on solving the global coupling, dynamics and mapping problems and building numerical models of increasing comprehensiveness and predictive power. In the area of observations, the corresponding emphasis is on coordinated campaigns and computerized data management, analyses and displays. Acknowledging the historical imperative of the time, the symposium assembled top people to relate progress toward quantitative empirical and theoretical understanding of all areas of the geospace system. The resulting global view of the state of our science shows great strength throughout, with areas of rapid progress and areas of difficult progress, but motion on all fronts. Under the pull of a common goal to achieve a fully predictive science of the geospace environment, we see the separate motions converging.
Loss of classicality in alternating spin-$\frac{1}{2}$/spin-$1$ chain, in the presence of next-neighbor couplings and Dzyaloshinskii-Moriya interactions (2020)

We have considered and alternating Heisenberg spin chain with nearest-neighbor ($J_1$), next-nearest neighbor ($J_2$) antiferromagnetic couplings along with z-component of the Dzyaloshinskii-Moriya(DM) ($D_z$) interactions. The Hamiltonian has been studied using (a) Linear Spin-Wave Theory(LSWT) and (b) Density Matrix Renormalization Group (DMRG). The system had been reported earlier as a classical ferrimagnet only when nearest neighbor exchange interactions are present. Both the antiferromagnetic next-nearest neighbor interactions and DM interactions introduce strong quantum fluctuations and due to which all the signatures of ferrimagnetism vanishes. We find that the nonzero $J_2$ introduces strong quantum fluctuations in each of the spin sites due to which the z-components of both spin-1 and spin-1/2 sites average out to be zero. The ground state becomes a singlet. The presence of $J_1$ along with $D_z$ introduces a short range order but develops long range order along the XY plane. $J_1$ along with $J_2$ induces competing phases with structure factor showing sharp and wide peaks, at two different angles reflecting the spin spiral structure locally as well as in the underlying lattice. Interestingly, we find that the $D_z$ term removes the local spin spiral structure in z-direction, while developing a spiral order in the XY plane.
Raman spectroscopy of single crystals of high-Tc cuprates (1989)

We present normal mode assignments for the Raman spectra of 1–2–3-type materials on the basis of polarized Raman studies of single crystals of Ba2YCu3O7, Ba2YCu3O6, Sr2YCu2.4Al0.6O7, and Ba2−xLa1+xCu3O7+δ. In Ba2YCu3O7 we observe five intrinsic modes at 500 [O(1) axial stretch], 435 [in-phase O(2), O(3) bend], 335 [out-of-phase O(2), O(3) bend], 140 [Cu(2) axial stretch mode], and 118 cm−1 (Ba axial mode). Defect-induced modes are found at 600 and 220 cm−1. A mode at 640 cm−1, which is seen only in ceramics, is shown to be due to a BaCuO2 impurity phase. Furthermore, we discuss the Raman spectra of Bi2Sr2Can−1CunO4+2n and the high-frequency (ω &gt; 1000 cm−1) scattering in Ba2YCu3O6 and Ba2YCu3O7.
Lignin Incorporation Combined with Electron-Beam Irradiation Improves the Surface Water Resistance of Starch Films (2004)

We investigated the potential of an electron-beam post-treatment to tailor the properties of 70/30 and 80/20 wt. extruded starch-lignin films. The effect of a 400 kGy radiation on films differing essentially by the kind of lignins incorporated (lignosulfonates/alkali lignins) was assessed both at the macroscopic and the molecular levels. Changes in the polymer molecular structure were studied by IR spectroscopy, by thioacidolysis as well as by model compound experiments. Electron beam-irradiation at 400 kGy, a rather high dose for processing natural polymers, alters to some extent the mechanical resistance of the starch-based materials. However this treatment substantially reduces the hydrophilic surface properties of the films, while not harming their biodegradability. Involved in radical cross-coupling reactions, lignin phenolic compounds are likely to play a primary role in the formation of a hydrophobic condensed network. This study suggests that lower irradiation doses might yield biomaterials with improved usage properties.
Compact three-mirror anastigmat with reflective lens (1998)

A uniquely packaged three-mirror anastigmat (TMA) is discussed. The telescope has 5 major parts, including the optics. This compact TMA exhibits diffraction-limited performance in the MWIR and LWIR wavelength regions and operates at fast F-numbers and relatively wide fields of view. Optical surfaces and critical mechanical interfaces are single-point diamond-turned, allowing for drop-together assembly and alignment. This paper discusses the evolution of the optical/mechanical design, developed under the auspices of the Standard Missile Company and NAVSEA PMS422.
Expert consensus on the importance of iron deficiency and the possibility of its correction in patients with heart failure. (2021)

Anemia and iron deficiency are common non-cardiovascular comorbidities of heart failure. The prevalence of iron deficiency is up to 55 % of patients with chronic heart failure and up to 80 % subjects with acute heart failure including acute decompensated heart failure, independently on anemia. The European Society of Cardiology Heart Failure Guidelines 2021 recommend intravenous iron replacement in patients with heart failure and iron deficiency to improve symptoms, stress tolerance and quality of life in chronic heart failure and to reduce risk of subsequent hospitalization after acute decompenstation.

Machine Learning and Artificial Intelligence for Surgical Decision Making (2021)

<b><i>Background:</i></b> The use of machine learning (ML) and artificial intelligence (AI) in medical research continues to grow as the amount and availability of clinical data expands. These techniques allow complex interpretation of data and capture non-linear relations not immediately apparent by classic statistical techniques. <b><i>Methods:</i></b> This review of the ML/AI literature provides a brief overview for practicing surgeons and clinicians of the current and future roles these methods will have within surgical infection research. <b><i>Results:</i></b> A conceptual overview of the techniques is provided along with concrete examples in the surgical infections literature. Further examples of ML/AI techniques in clinical decision support as well as therapy discovery with model-based deep reinforcement learning are illustrated. <b><i>Conclusions:</i></b> Artificial intelligence and ML are important and increasingly utilized techniques within the expanding body of surgical infection research. This article provides a minimal baseline literacy in ML/AI to be able to view such projects in an appropriately critical fashion.
Mammographic breast density classification using a deep neural network: assessment on the basis of inter-observer variability (2019)

Mammographic breast density is an important risk marker in breast cancer screening. The ACR BI-RADS guidelines (5th ed.) define four breast density categories that can be dichotomized by the two super-classes &#100;ense" and &#110;ot dense". Due to the qualitative description of the categories, density assessment by radiologists is characterized by a high inter-observer variability. To quantify this variability, we compute the overall percentage agreement (OPA) and Cohen's kappa of 32 radiologists to the panel majority vote based on the two super-classes. Further, we analyze the OPA between individual radiologists and compare the performances to an automated assessment via a convolutional neural network (CNN). The data used for evaluation contains 600 breast cancer screening examinations with four views each. The CNN was designed to take all views of an examination as input and trained on a dataset with 7186 cases to output one of the two super-classes. The highest agreement to the panel majority vote (PMV) achieved by a single radiologist is 99%, the lowest score is 71% with a mean of 89%. The OPA of two individual radiologists ranges from a maximum of 97.5% to a minimum of 50.5% with a mean of 83%. Cohen's kappa values of radiologists to the PMV range from 0.97 to 0.47 with a mean of 0.77. The presented algorithm reaches an OPA to all 32 radiologists of 88% and a kappa of 0.75. Our results show that inter-observer variability for breast density assessment is high even if the problem is reduced to two categories and that our convolutional neural network can provide labelling comparable to an average radiologist. We also discuss how to deal with automated classification methods for subjective tasks.

Performance analysis of the ieee 802.16 arq mechanism (2007)

The IEEE 802.16 technology defines the ARQ mechanism that enables a connection to resend data at the MAC level if an error is detected. In this paper, we analyze the key features and parameters of the 802.16 ARQ mechanism. In particular, we consider a choice for the ARQ feedback type, an algorithm to build block sequences, a scheduling of the ARQ feedbacks and retransmissions, the ARQ block rearrangement, ARQ transmission window and ARQ block size. We run a number of simulation scenarios to study these parameters and how they impact a performance of application protocols. The simulation results reveal that the ARQ mechanism and its correct configuration play an important role in transmitting data over wireless channels in the IEEE 802.16 networks.
