Using modelled relationships and satellite observations to attribute modelled aerosol biases over biomass burning regions (2022)

Biomass burning (BB) is a major source of aerosols that remain the most uncertain components of the global radiative forcing. Current global models have great difficulty matching observed aerosol optical depth (AOD) over BB regions. A common solution to address modelled AOD biases is scaling BB emissions. Using the relationship from an ensemble of aerosol models and satellite observations, we show that the bias in aerosol modelling results primarily from incorrect lifetimes and underestimated mass extinction coefficients. In turn, these biases seem to be related to incorrect precipitation and underestimated particle sizes. We further show that boosting BB emissions to correct AOD biases over the source region causes an overestimation of AOD in the outflow from Africa by 48%, leading to a double warming effect compared with when biases are simultaneously addressed for both aforementioned factors. Such deviations are particularly concerning in a warming future with increasing emissions from fires.
Posttraumatic Cerebral Ischemia after Fluid Percussion Brain Injury: An Autoradiographic and Histopathological Study in Rats (1998)

These data indicate that multiple cerebrovascular abnormalities, including subarachnoid hemorrhage, focal platelet accumulation, and severe ischemia, are important early events in the pathogenesis of cortical contusion formation after TBI. Injury severity is expected to be a critical factor in determining what therapeutic strategies are attempted in the clinical setting.
Understanding of the Growth Mechanism Leading to Twin Boundary Elimination during 3C-SiC Heteroepitaxy on α-SiC Substrate by CVD (2015)

Starting from the previously demonstrated twin-free 3C-SiC growth on 4H-SiC when using Ge pre-deposition treatment, this work focuses on the understanding of the growth mechanism that stands behind this result. Toward this end, short growth experiments were performed to allow the investigation of the nucleation stage. Based on the experimental observations, a mechanism is proposed which involves a Ge-induced transient homoepitaxial growth step followed by 3C nucleation when large terraces are formed by step faceting. Lateral expansion of the 3C islands leads to orientation selection and twin boundary elimination. Similar results can be obtained when applying a Si-based pre-deposition treatment so that the crucial transient homoepitaxial step is promoted in fact by the presence of a liquid phase itself, no by its chemical nature.

Healthcare Workers' Perceptions of Mandatory Vaccination: Results of an Anonymous Survey in a German University Hospital (2010)

Despite decades of effort to encourage healthcare workers (HCWs) to be immunized, vaccination rates remain insufficient. Among German HCWs, 831 (68.4%) of 1,215 respondents supported mandatory vaccinations for HCWs in general. However, acceptance of mandatory vaccination varied significantly between physicians and nurses and also depended on the targeted disease.
Metasurface-dressed two-dimensional on-chip waveguide for free-space light field manipulation (2022)

We show that a metasurface-coated two-dimensional (2D) slab waveguide enables the generation of arbitrary complex light fields by combining the extreme versatility and freedom on wavefront control of optical metasurfaces with the compactness of photonic integrated circuits. We demonstrated off-chip 2D focusing and holographic projection with our metasurface-dressed photonic integrated devices. This technology holds the potential for many other optical applications requiring 2D light field manipulation with full on-chip integration, such as solid-state LiDAR and near-eye AR/VR displays.
The Build Up of Population of the Red Scale Aonidiella aurantii (Maskell) on Citrus Trees in Egypt (1972)

Abstract The red scale Aonidiella aurantii (Maskell) prefers conditions of moderate temperatures with low relative humidity. It passes through four annual generations in Middle Egypt and Nile‐Delta and only three generations in the north coastal areas where the relative humidity is high. The average annual fluctuation for this species ranges from 2.4 to 4.7. The optimum temperature conditions for the insect development range between 21.2 and 26.9° C. The mode of the insect distribution on different zones of citrus trees during different seasons and in different localities of the U.A.R. show that the lower zones as well as the central shady cores of the trees tend to harbour the highest insect population. The lowest population, on the other hand is always accumulated on the uppermost sunny zones of the trees. The photonegative reaction of the insect crawlers seems to be an important factor regulating the insect distribution on the trees. Zusammenfassung Über den Aufbau der Population bei der Roten Schildlaus Aonidiella aurantii (Maskell) auf Zitrusbäumen in Ägypten A. aurantii bevorzugt eine Verbindung von gemäßigten Temperaturen mit niedriger Luftfeuchte. Sie hat 4 Generationen jährlich im mittleren Ägypten und Nildelta, dagegen nur 3 in den Küstengebieten, wo die Luftfeuchte relativ hoch ist. Ihre mittlere jährliche Fluktuation beträgt 2,4–4,7. Der für ihre Entwicklung optimale Temperaturbereich liegt zwischen 21,2 und 26,9° C. Untersuchungen über die Verteilung der Schildlaus‐Population am Baum zeigten, daß der Schädling sowohl die unteren Zonen der Kronen als auch das schattige Innere bevorzugte. Die geringste Dichte fand sich stets in den oberen sonnigen Zonen. Für diese Verteilung dürfte die photonegative Reaktion der beweglichen Schildläuse verantwortlich sein.
Superconductivity in a disordered metal with unscreened Coulomb interactions (2020)

We study the electronic densities of states (DOS) of strongly disordered superconducting thin films of TiN. We find, using Scanning Tunneling Microscopy (STM) that the DOS decreases towards the Fermi level in the normal phase obtained by applying magnetic fields. The DOS shows spatial fluctuations whose length scale is related to the energy dependent DOS and is similar in normal and superconducting phases. This suggests that Coulomb interactions lead to a spatially varying DOS in the normal phase of a disordered superconductor.

Lightweight Directory Access Protocol (v3): Extensions for Dynamic Directory Services (1999)

This document defines the requirements for dynamic directory services and specifies the format of request and response extended operations for supporting client-server interoperation in a dynamic directories environment.The Lightweight Directory Access Protocol (LDAP) [1] supports lightweight access to static directory services, allowing relatively fast search and update access.Static directory services store information about people that persists in its accuracy and value over a long period of time.Dynamic directory services are different in that they store information that only persists in its accuracy and value when it is being periodically refreshed.This information is stored as dynamic entries in the directory.A typical use will be a client or a person that is either online -in which case it has an entry in the directory, or is offline -in which case its entry disappears from the directory.Though the protocol operations and attributes used by dynamic directory services are similar to the ones used for static directory services, clients that store dynamic information in the directory need to periodically refresh this information, in order to prevent it from disappearing.If dynamic entries are not refreshed Yaacovi, et al.
Safe futures for Java (2005)

A future is a simple and elegant abstraction that allows concurrency to be expressed often through a relatively small rewrite of a sequential program. In the absence of side-effects, futures serve as benign annotations that mark potentially concurrent regions of code. Unfortunately, when computation relies heavily on mutation as is the case in Java, its meaning is less clear, and much of its intended simplicity lost.This paper explores the definition and implementation of safe futures for Java. One can think of safe futures as truly transparent annotations on method calls, which designate opportunities for concurrency. Serial programs can be made concurrent simply by replacing standard method calls with future invocations. Most significantly, even though some parts of the program are executed concurrently and may indeed operate on shared data, the semblance of serial execution is nonetheless preserved. Thus, program reasoning is simplified since data dependencies present in a sequential program are not violated in a version augmented with safe futures.Besides presenting a programming model and API for safe futures, we formalize the safety conditions that must be satisfied to ensure equivalence between a sequential Java program and its future-annotated counterpart. A detailed implementation study is also provided. Our implementation exploits techniques such as object versioning and task revocation to guarantee necessary safety conditions. We also present an extensive experimental evaluation of our implementation to quantify overheads and limitations. Our experiments indicate that for programs with modest mutation rates on shared data, applications can use futures to profitably exploit parallelism, without sacrificing safety.
Plasma sprayed basalt/chromium oxide coatings (2007)

Volcanic basalt and chromium oxide (Cr2O3) have been co-sprayed in air with a direct current (d.c.) plasma to obtain composite coatings. Both powders were simultaneously injected by two separated injectors. The following spray parameters: arc current, hydrogen vol % and total plasma forming gas mass flow rate were optimized as well as injector positions. Different mass ratios of both components were used to achieve coatings. An uniform distribution of basalt among the Cr2O3 lamellae has been observed with SEM for all composite coatings. XRD showed that chromia became amorphous in the composite basalt/chromia coatings.
Retargeting Web pages to other computing platforms with VAQUITA (2003)

Mobile platforms are becoming an increasingly important alternative for accessing Web pages. Many Web pages are not suited to these platforms and need to be adapted, or rewritten from scratch. Adaptation can be carried out in two ways: either by dynamic conversion or static reengineering. VAQUITA belongs to the second category by applying a model-based approach to reverse engineer Web pages at a certain level of abstraction to transfer them to other computing platforms afterwards. Instead of reverse engineering a presentation model and translating it into another model specified for a particular platform, this paper proposes reverse engineering tailored for any target platform, even one not yet defined. The essence of this reverse engineering approach involves composing several functions of abstraction, reflection, translation, and reification into two steps: retargeting and regenerating a Web page to another platform.
Design of Miniaturized Dual-Band Microstrip Antenna for WLAN Application (2016)

Wireless local area network (WLAN) is a technology that combines computer network with wireless communication technology. The 2.4 GHz and 5 GHz frequency bands in the Industrial Scientific Medical (ISM) band can be used in the WLAN environment. Because of the development of wireless communication technology and the use of the frequency bands without the need for authorization, the application of WLAN is becoming more and more extensive. As the key part of the WLAN system, the antenna must also be adapted to the development of WLAN communication technology. This paper designs two new dual-frequency microstrip antennas with the use of electromagnetic simulation software-High Frequency Structure Simulator (HFSS). The two antennas adopt ordinary FR4 material as a dielectric substrate, with the advantages of low cost and small size. The first antenna adopts microstrip line feeding, and the antenna radiation patch is composed of a folded T-shaped radiating dipole which reduces the antenna size, and two symmetrical rectangular patches located on both sides of the T-shaped radiating patch. The second antenna is a microstrip patch antenna fed by coaxial line, and the size of the antenna is diminished by opening a stepped groove on the two edges of the patch and a folded slot inside the patch. Simulation experiments prove that the two designed antennas have a higher gain and a favourable transmission characteristic in the working frequency range, which is in accordance with the requirements of WLAN communication.
Waveguide grating mirror for large-area semiconductor lasers (2001)

We have fabricated and tested a waveguide grating mirror that uses anomalous reflection of light associated with excitation of waveguide modes. Sharp features are observed in the reflection spectra in both the wavelength and the angular domains. We confirm experimentally that, when the waveguide grating mirror is placed a short distance in front of a large-area semiconductor laser, it can control the emission spectrum. This demonstration opens a new approach to the design of very compact semiconductor lasers operating in the single-frequency-single-mode regime.
INTRADERMAL IMMUNIZATION AGAINST ASIAN INFLUENZA IN CHILDREN (1959)

The effectiveness of intradermally injected vaccine against Asian influenza was studied in an orphanage in Memphis, Tenn., with 168 children between the ages of 1 and 17 years. A single lot of monovalent Asian strain type A influenza vaccine containing 200 chick cell agglutination units per milliliter was used throughout the study. The outbreak of influenza in the orphanage began on the same day as in the city of Memphis. Four cases occurred before the first injection, 17 between the first and second, and 5 after the second. The outbreak in the orphanage had substantially ceased before the citywide epidemic had reached its peak. Comparison of the hemagglutination-inhibition titers of serum samples obtained before and after the injections, with a consideration of the time relation of the cases among the different age groups in the orphanage, indicated that the vaccine was effective when given intradermally.
Use of Herbals as Galactagogues (2012)

With a substantial number of women using herbal products to augment their milk production, this article will review available literature illustrating efficacy and adverse effects of using these products. Embase, PubMed, and EBSCO (all databases) were searched from inception to June 2011 using terms such as “galactagogue,” “galactogogue,” “herbal,” and “botanical” and the search was subsequently narrowed to specific herbals by name. Additional articles were obtained from article reference lists. Supplemental information was obtained with Natural Standard. All abstracts retrieved were evaluated for relevance and germane articles were included. Numerous lactation-stimulating herbals have been identified in the literature with varying degrees of evidence, mostly anecdotal. Use of torbangun, milk thistle, and fenugreek may correlate with increased milk supply. Evidence regarding adverse effects, pharmacodynamic properties, and pharmacokinetic effects remains scarce. Despite the fact that postpartum women may turn to herbal galactagogues, scant clinical evidence exists to justify their effectiveness. Further clinical trials are needed in order to substantiate these findings.
Epipolargeometrie bei heterogenen Stereokamerasystemen (2014)

In den letzten Jahrzehnten wuchs der Markt für Kameras mit nichtperspektivischen Abbildungsverhalten beträchtlich. Insbesondere Kamerasysteme mit großem Öffnungswinkel finden zunehmend Verwendung. Analog zu klassischen, homogenen Stereosystemen, die aus zwei perspektivisch abbildenden Kameras bestehen, ist die Kombination verschiedenartiger Kamerasysteme denkbar.&#13;\nIn diesem Artikel untersuchen wir die Epipolargeometrie bei heterogenen Stereokamerasystemen mit generischen Abbildungsmodellen. Wir präsentieren eine analytische Lösung für die Transformation eines beliebigen Bildpunktes einer Kamera in seine Epipolarrepräsentation der zweiten Kamera. Zusätzlich haben wir einen Blockmatcher implementiert, um in diesen heterogenen Systemen eine Disparitätskarte zu erstellen. Die Ergebnisse zeigen, dass die so erzeugten Disparitätskarten trotz unterschiedlicher Abbildungseigenschaften der jeweiligen Kamera relativ genau werden.
Involvement of striatal and extrastriatal DARPP-32 in biochemical and behavioral effects of fluoxetine (Prozac) (2002)

Fluoxetine (Prozac) is the most widely prescribed medication for the treatment of depression. Nevertheless, little is known about the molecular basis of its clinical efficacy, apart from the fact that fluoxetine increases the synaptic availability of serotonin. Here we show that, in vivo, fluoxetine, given either acutely or chronically, regulates the phosphorylation state of dopamine- and cAMP-regulated phosphoprotein of M(r) 32,000 (DARPP-32) at multiple sites in prefrontal cortex, hippocampus, and striatum. Acute administration of fluoxetine increases phosphorylation of DARPP-32 at the protein kinase A site, Thr-34, and at the casein kinase-1 site, Ser-137, and decreases phosphorylation at the cyclin-dependent kinase 5 site, Thr-75. Each of these changes contributes, through distinct signaling pathways, to increased inhibition of protein phosphatase-1, a major serine/threonine protein phosphatase in the brain. Fluoxetine also increases phosphorylation of the alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptor subunit GluR1 at Ser-831 and Ser-845. Both the fluoxetine-mediated increase in AMPA receptor phosphorylation at Ser-845-GluR1 and the beneficial responsiveness to fluoxetine in an animal test of antidepressant efficacy were strongly reduced in DARPP-32 knockout mice, indicating a critical role for this phosphoprotein in the antidepressant actions of fluoxetine. Mice chronically treated with fluoxetine had increased levels of DARPP-32 mRNA and protein and a decreased ability to increase phospho-Ser-137-DARPP-32 and phospho-Ser-831-GluR1. These chronic changes may be relevant to the delayed onset of therapeutic efficacy of fluoxetine.
Somatically Hypermutated Plasmodium-Specific IgM+ Memory B Cells Are Rapid, Plastic, Early Responders upon Malaria Rechallenge (2016)

Humoral immunity consists of pre-existing antibodies expressed by long-lived plasma cells and rapidly reactive memory B cells (MBC). Recent studies of MBC development and function after protein immunization have uncovered significant MBC heterogeneity. To clarify functional roles for distinct MBC subsets during malaria infection, we generated tetramers that identify Plasmodium-specific MBCs in both humans and mice. Long-lived murine Plasmodium-specific MBCs consisted of three populations: somatically hypermutated immunoglobulin M(+) (IgM(+)) and IgG(+) MBC subsets and an unmutated IgD(+) MBC population. Rechallenge experiments revealed that high affinity, somatically hypermutated Plasmodium-specific IgM(+) MBCs proliferated and gave rise to antibody-secreting cells that dominated the early secondary response to parasite rechallenge. IgM(+) MBCs also gave rise to T cell-dependent IgM(+) and IgG(+)B220(+)CD138(+) plasmablasts or T cell-independent B220(-)CD138(+) IgM(+) plasma cells. Thus, even in competition with IgG(+) MBCs, IgM(+) MBCs are rapid, plastic, early responders to a secondary Plasmodium rechallenge and should be targeted by vaccine strategies.
Vaginal Progesterone Is as Effective as Cervical Cerclage to Prevent Preterm Birth in Women With a Singleton Gestation, Previous Spontaneous Preterm Birth, and a Short Cervix: Updated Indirect Comparison Meta-analysis (2018)

(Abstracted from Am J Obstet Gynecol 2018;219(1):10–25) It is widely accepted that preterm birth is a syndrome caused by several pathological processes such as infection, vascular and decidual disorders, uterine overdistension, breakdown of maternal fetal tolerance, a decline in progesterone action, and cervical disease. A previous spontaneous preterm birth is a well-known risk factor for recurrent spontaneous preterm delivery.
