Challenges and Opportunities in the Adoption of College of American Pathologists Checklists in Electronic Format: Perspectives and Experience of Reporting Pathology Protocols Project (RPP2) Participant Laboratories (2010)

Abstract Context. —The site-specific cancer checklists developed by the College of American Pathologists have the potential to improve the quality of data derived from pathology reports and incorporated into cancer registry databases and are now mandated report elements by various accrediting bodies. A pilot project, funded by the Centers for Disease Control National Project for Cancer Registries in 2004, brought 4 pathology services in 3 states, with differing baseline implementations of the checklists, the opportunity to partner with their state National Project for Cancer Registry and their laboratory information system vendors to evaluate the feasibility of using electronically encoded College of American Pathologists cancer checklists for melanoma and tumors of the breast and prostate. Objectives. —To identify existing and potential barriers to adoption of electronically encoded checklists and to also identify unique benefits not associated with text-only uses of the checklists. Design. —Participants mapped an implementation process from their current state to an electronic checklist–capable state. For a sample of cases of melanoma, prostate, and breast cancers, the checklist elements were captured and transmitted to the registry using Health Level 7 (version 2.3.1). Process assessments with adoption of electronic checklists were conducted to assess pathologist effect and other potential barriers. An evaluation of the utility and usefulness of electronic checklists was performed after the project. Results. —All 4 laboratories successfully performed the capture of individual data elements from the College of American Pathologists checklist into a discrete format suitable for electronic transmission. The effect on pathologist performance and laboratory workflow was neutral. Points of resistance were identified in the checklists and in individual users. Specific challenges in individual laboratories varied according to the personnel and the baseline system in use. Clinical responses to implemented changes were generally positive. Analysis of the postproject experiences of the laboratories showed expansion of use and additional utility in some, but not all, laboratories. Conclusions. —Pathology laboratory adoption of the College of American Pathologists cancer checklists in an electronic format suited to direct transmission to cancer registries poses business case, information technology, and human resource challenges. Laboratory information system vendor readiness to upgrade systems to facilitate this process helps to reduce some of these challenges. Personalities and preferences in practices may yet pose barriers to widespread adoption.
Robust Semi-Supervised Learning when Labels are Missing at Random. (2018)

Semi-supervised learning methods are motivated by the availability of large datasets with unlabeled features in addition to labeled data. Unlabeled data is, however, not guaranteed to improve classification performance and has in fact been reported to impair the performance in certain cases. A fundamental source of error arises from restrictive assumptions about the unlabeled features, which result in unreliable classifiers that underestimate their prediction error probabilities. In this paper, we develop a semi-supervised learning approach that relaxes such assumptions and is capable of providing classifiers that reliably quantify the label uncertainty. The approach is applicable using any generative model with a supervised learning algorithm. We illustrate the approach using both handwritten digit and cloth classification data where the labels are missing at random.
Fast power transients in WDMoptical networks with cascaded EDFAs (1997)

Power transients arising from cross-saturation in erbium-doped fibre amplifiers (EDFAs) are generally thought to be slower than 100 µs due to the slow gain dynamics. This is a key advantage of EDFAs. The authors report on power transients of 1 dB in &lt;3 µs in a chain of five EDFAs. These fast power variations result from the collective behaviour of the amplifier chain.

Synthesis of gold nanoparticles on petal-shaped silica by solution plasma (2011)

Spherical silica and gold nanoparticles were attempted to be prepared by solution plasma. The silica was prepared from the following solutions by solution plasma treatment. Those are (a) tetraethoxysilane, ethanol, water and hexadecylamine (TEOS-EtOH-H2O-HDA) system and (b) tetraethoxysilane, ethanol, water, hexade-cylamine and aurochloric acid (TEOS-EtOH-H2O-HDA-HAuCl4 ) system. In the system (a), the spherical silica was produced. While, in the system (b), gold nanoparticles supported petal-shaped silica were produced. These shapes differs from the one prepared from the conventional acid and base solutions stober method.
WDM Signal All-Optical Precompensation of Kerr Nonlinearity in Dispersion-Managed Fibers (2012)

Compensation of the Kerr nonlinearity in dispersion-managed optical fiber links is demonstrated for 100-GHz-spaced wavelength division multiplexing (WDM) 40-Gb/s return-to-zero-differential phase-shift keying signals using all-optical nonlinear predistortion and phase-conjugation at the transmitter. Measurements of the bit-error rate (BER) reveal a Q <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> -factor improvement from 1.3 to 2.9 dB for transmission of one to four WDM channels in a standard single-mode fiber link. Although signal distortion is primarily from intrachannel nonlinearity, the BER is also degraded by linear and nonlinear interchannel crosstalk.

Highly Effective Solid Electrolyte Interphase-Forming Electrolyte Additive Enabling High Voltage Lithium-Ion Batteries (2017)

The electrochemical and thermal stabilities of commonly used LiPF6/organic carbonate-based electrolytes are still a bottleneck for the development of high energy density lithium-ion batteries (LIBs) operating at elevated cell voltage and elevated temperature. The use of intrinsic electrochemically stable electrolyte solvents, e.g. sulfones or dinitriles, has been reported as one approach to enable high voltage LIBs. However, the major challenge of these solvents is related to their poor reductive stability and lack of solid electrolyte interphase (SEI)-forming ability on the graphite electrode. Here, 3-methyl-1,4,2-dioxazol-5-one (MDO) is synthesized and investigated as new highly effective SEI-forming electrolyte additive which can sufficiently suppress electrolyte reduction and graphite exfoliation in propylene carbonate (PC)-based electrolytes. With the addition of only 2 wt % MDO, LiNi0.5Mn0.3Co0.2O2 (NMC532)/graphite full cells containing a 1 M LiPF6 in PC electrolyte reach a cycle life of more than 450 cycles while still having a capacity retention of 80%. In addition, MDO has proven to be oxidatively stable until potentials as high as 5.3 V vs Li/Li+. Further development of MDO and its derivatives as electrolyte additives is a step forward to high voltage stable electrolyte formulations based on alternative electrolyte solvents and high energy density LIBs.
Do GSM 900MHz signals affect cerebral blood circulation? A near-infrared spectrophotometry study (2006)

Effects of GSM 900MHz signals (EMF) typical for a handheld mobile phone on the cerebral blood circulation were investigated using near-infrared spectrophotometry (NIRS) in a three armed (12W/kg, 1.2W/kg, sham), double blind, randomized crossover trial in 16 healthy volunteers. During exposure we observed borderline significant short term responses of oxyhemoglobin and deoxyhemoglobin concentration, which correspond to a decrease of cerebral blood flow and volume and were smaller than regular physiological changes. Due to the relatively high number of statistical tests, these responses may be spurious and require further studies. There was no detectable dose-response relation or long term response within 20min. The detection limit was a fraction of the regular physiological changes elicited by functional activation. Compared to previous studies using PET, NIRS provides a much higher time resolution, which allowed investigating the short term effects efficiently, noninvasively, without the use of radioactive tracers and with high sensitivity.
Resource Usage Strategies and Trade-Offs between Cropland Demand, Fossil Fuel Consumption, and Greenhouse Gas Emissions—Building Insulation as an Example (2016)

Bioresources are used in different production systems as materials as well as energy carriers. The same is true for fossil fuel resources. This study explored whether preferential resource usages exist, using a building insulation system as an example, with regard to the following sustainability criteria: climate impact, land, and fossil fuel demand. We considered the complete life cycle in a life cycle assessment-based approach. The criteria were compared for two strategies: one used natural fibers as material and generated production energies from fossil fuels; the other generated production energies from bioenergy carriers and transformed fossil resources into the insulation material. Both strategies finally yielded the same insulation effect. Hence, the energy demand for heating the building was ignored. None of the strategies operated best in all three criteria: While cropland demand was lower in the bioenergy than in the biomaterial system, its fossil fuel demand was higher. Net contribution to climate change was in the same range for both strategies if we considered no indirect changes in land use. Provided that effective recycling concepts for fossil-derived insulations are in place, using bioresources for energy generation was identified as a promising way to mitigate climate change along with efficient resource use.
Hemorrhage from moyamoya-like vessels associated with a cerebral arteriovenous malformation (2004)

The authors describe a case of subarachnoid hemorrhage from moyamoya-like vessels associated with an arteriovenous malformation (AVM) in a 44-year-old Hispanic man who presented with severe headache. The AVM was located in the left parietal lobe and the ipsilateral middle cerebral artery was occluded. Although the patient was initially neurologically intact, he began to experience neurological deficits from mild vasospasm, illustrating the sensitivity of the underperfused portion of brain surrounding an AVM. His neurological deficits improved with aggressive hydration and elevated blood pressure. After a 3-week period, the AVM was resected without complication and all of the patient's neurological deficits resolved. The authors review radiographic findings of this unique case.
A platform for device and computation management (2005)

Mobile computing extends the horizons of conventional computing model to a ubiquitous computing environment that serves users at anytime, anywhere. Most distributed applications and services were designed with the assumption that the terminals were powerful, stationary and connected to fixed networks. One of the biggest challenges in future application development is device heterogeneity. In the future, we expect to see a rich variety of computing devices that can run applications. These devices have different capabilities in processors, memory, networking, screen sizes, input methods, and software libraries. We also expect that future users are likely to own many types of devices. Depending on users changing situations and environments, they may choose to switch from one type of device to another that brings the best combination of application functionality and device mobility. Applications, middleware, and systems can be measured in a variety of dimensions, including usability, distributability, integration, conformance to standards, extensibility, internationalizability, manageability, performance, portability, scalability reliability- fault tolerance and security. We call these pervasive attributes, since they can apply to the system as a whole, not just to the system's components. In this paper we have designed and implemented a secure and reliable application framework called the Platform for Device and Computation Management (PDCM) system that can both assist developers to build multi-platform applications that can run on heterogeneous devices and allow a user to move/migrate a running application among heterogeneous devices.
Multivalent anthelminthic vaccine to prevent hookworm and schistosomiasis (2008)

Hookworm infection and schistosomiasis are two of the world's most important human parasitic infections, affecting hundreds of millions of people in developing countries. Measured together in disability-adjusted life years, hookworm infection and schistosomiasis rank closely behind malaria as the most prevalent human parasitic diseases. A major approach for the control of these two helminth infections relies on periodic, mass chemotherapy with anthelminthics. However, high rates of post-treatment reinfection, the declining efficacy with repeated treatment, rebound morbidity (in the case of schistosomiasis) and the potential for the emergence of anthelminthic drug resistance threaten the sustainability of mass drug administration as the only form of control. Hence, there is a strong rationale for developing a vaccine that simultaneously targets both hookworms and schistosomes because of similarities in the pathobiology of both parasites, the ability of both helminths to cause anemia and their coendemicity in sub-Saharan Africa, Brazil and East Asia. A multivalent anthelminthic vaccine for hookworm infection and schistosomiasis would represent an important new tool for combating disease and poverty.
Approved Lists of Bacterial Names (Amended) (1989)

At the meeting of the Judicial Commission of the ICSB held in Jerusalem on the 29th March, 1973 an Ad Hoc Committee was appointed (Minute 22) to organize a review of the currently valid names of bacteria with the object of retaining only names for those taxa which were adequately described and, if cultivable, for which there was a Type, Neotype or Reference strain available; to compile these names under the title of Approved Lists of Bacterial Names and to publish the lists in the International Journal of Systematic Bacteriology, to become effective on January 1, 1980. This date would then replace May 1, 1753 (International Code of Nomenclature of Bacteria and Viruses. Rule 10) as the new date for determining priorities for names of new taxa.The Approved Lists of Bacterial Names was published in the International Journal of Systematic Bacteriology (IJSB 30: 225–420, 1980) and reprinted in book form to provide for the requirements of the Bacteriological Code (1976 Revision) in initiating a new starting date for bacterial nomenclature, 1 January 1980. Despite every care, errors in the text have been detected and these errors have now been corrected in this Amended Edition.
Aromatic annelation by reaction of arylimidoyl radicals with alkynes: a new synthesis of quinolines (1984)

Image Browsing and Natural Language Paraphrases of Semantic Web Annotations (2006)

Abstract. Recently, there has been interest in marking up digital images with annotations describing the content of the images using Web based ontologies encoded in the W3C’s Web Ontology Language, OWL. The annotations are subsequently exploited to improve the user experience of large collections of images, whether by enhance search or by a structured browsing experience. In the latter case, the complexity and unfamiliarity of logic-based ontology languages may do more to impede, than aid, the user. To alleviate this problem, we propose using automatic generation of natural language (NL) paraphrases of OWL statements to assist browsing image content. In this paper, we provide an overview of our NL generation approach and an empirical evaluation of the use of our paraphrases for image browsing. 1
23.5% thin-film space concentrator cells (2002)

Thin-film AlGaAs-GaAs double-heterostructure concentrator cells were fabricated which exhibit total-area conversion efficiencies as high as 23.5% AM0 at 100 suns, 25 degrees C. This is one of the best space concentrators measured to date at NASA and is designed for a thin-film cell without a prismatic coverglass. This solar cell structure consists of a GaAs/AlGaAs film less than 5 mu m thick mounted to a glass cover/superstrate, with coplanar back-side contacts. The coverglass is not prismatic. The CLEFT process, a method for mechanically separating epitaxial. layers from their substrate, is used to process these cells into thin films. The advantages of single-crystal GaAs are thereby retained, while reducing weight and cutting cost by allowing for substrate reuse. Thin-film cells also have better thermal management capabilities and can be stacked for use in tandem structures. Cell fabrication and performance are described, and directions for further improvements are identified.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Charge transport, injection, and photovoltaic phenomena in oligo(phenylenevinylene) based diodes (2003)

Abstract We report on the charge transport and injection phenomena of ( E , E , E , E )‐1,4‐bis[(4‐styryl)styryl]‐2‐methoxy‐5‐(2′‐ethylhexoxy)benzene (MEH‐OPV5) sandwiched between asymmetric contacts. The hole mobility of MEH‐OPV5 was determined by means of transient electroluminescence. The steady‐state current was injection‐limited. The electric field and temperature dependence of the current were quantitatively described by a phenomenological injection model of thermally assisted charge‐carrier tunneling in a one‐dimensional chain of hopping sites. Furthermore, we report on the photovoltaic properties of thin‐film photovoltaic cells on the basis of donor–acceptor heterojunctions. MEH‐OPV5 and buckminster fullerene were used as the donor and acceptor materials, respectively. The emphasis was on the role of morphology in such devices. © 2003 Wiley Periodicals, Inc.

Effects of Light and CO on the Survival of a Marine Ammonium-Oxidizing Bacterium during Energy Source Deprivation (1988)

The chemolithotrophic ammonium-oxidizing bacterium Nitrosomonas cryotolerans responds uniquely to nutrient deprivation by lowering its endogenous respiration and anabolic processes to undetectable levels during starvation, thus appearing to enter a dormant state. To ascertain whether this state protects the cells from further stresses (as seen with endospore-forming bacteria), the starved cells were subjected to two known inhibitors, CO and light. It was found that long-term-starved cells were less resistant than freshly starved cells to light inhibition. Both long-term-starved cells and freshly starved cells were unaffected by CO.
Characterization Of Superconducting Samples With SIC System For Thin Film Developments: Status And Recent Results (2013)

Within any thin film development program directed towards SRF accelerating structures, there is a need for an RF characterization device that can provide information about RF properties of small samples. The current installation of the RF characterization device at Jefferson Lab is Surface Impedance Characterization (SIC) system. The data acquisition environment for the system has recently been improved to allow for automated measurement, and the system has been routinely used for characterization of bulk Nb, films of Nb on Cu, MgB$_{2}$, NbTiN, Nb$_{3}$Sn films, etc. We present some of the recent results that illustrate present capabilities and limitations of the system.
