Don't Let Notes Be Misunderstood: A Negation Detection Method for Assessing Risk of Suicide in Mental Health Records (2016)

Mental Health Records (MHRs) contain freetext documentation about patients' suicide and suicidality. In this paper, we address the problem of determining whether grammatic variants (inflections) of the word "suicide" are affirmed or negated. To achieve this, we populate and annotate a dataset with over 6,000 sentences originating from a large repository of MHRs. The resulting dataset has high Inter-Annotator Agreement ( 0.93). Furthermore, we develop and propose a negation detection method that leverages syntactic features of text 1 . Using parse trees, we build a set of basic rules that rely on minimum domain knowledge and render the problem as binary classification (affirmed vs. negated). Since the overall goal is to identify patients who are expected to be at high risk of suicide, we focus on the evaluation of positive (affirmed) cases as determined by our classifier. Our negation detection approach yields a recall (sensitivity) value of 94.6% for the positive cases and an overall accuracy value of 91.9%. We believe that our approach can be integrated with other clinical Natural Language Processing tools in order to further advance information extraction capabilities.

A labelled-ubiquicidin antimicrobial peptide for immediate in situ optical detection of live bacteria in human alveolar lung tissue (2015)

The <i>in situ</i> immediate detection of the presence of bacteria in the distal human lung is of significant clinical utility. Herein we describe the development and optimization of a bacterial binding fragment (UBI<sub>29-41</sub>) of the antimicrobial peptide, ubiquicidin (UBI), conjugated to an environmentally sensitive fluorophore to enable rapid live bacterial imaging within human lung tissue. UBI<sub>29-41</sub> was modified for stability in the presence of human lung bronchoalveolar lavage fluid, for affinity to bacterial membranes and functionality in human lung tissue. The optimized cyclic structure yields an optical molecular Smartprobe for bacterial detection in human lung tissue.
Video matting using motion extended GrabCut (2008)

GrabCut is perhaps the most powerful semi-automatic algorithm for matting presented to date. In its existing form, it is not suitable for video object segmentation. This paper considers major extensions that make it suitable for this purpose. A method for initialising matting without user intervention is presented, followed by a more robust data model using a mean shift algorithm to control model complexity. In addition, normalised motion information as well as colour is used to form joint colour and motion feature vectors. This improves the robustness of the mattes in the presence of colour camouflage and decreases the user intervention required for a successful result. Comparison between GrabCut and the proposed Motion Extended GrabCut (MxGrabCut), shows the improvement for video matting. (9 pages)
A fully programmable 100-spin coherent Ising machine with all-to-all connections (2017)

Unconventional, special-purpose machines may aid in accelerating the solution of some of the hardest problems in computing, such as large-scale combinatorial optimizations, by exploiting different operating mechanisms than those of standard digital computers. We present a scalable optical processor with electronic feedback that can be realized at large scale with room-temperature technology. Our prototype machine is able to find exact solutions of, or sample good approximate solutions to, a variety of hard instances of Ising problems with up to 100 spins and 10,000 spin-spin connections.
OWA Operators in Data Modeling and Reidentification (2004)

This paper is devoted to the application of aggregation operators and to the application of ordered weighting averaging (OWA) operators to data mining. In particular, we consider two application of OWA operators in this field: model building and information extraction. The latter application is oriented to the reidentification procedures.
Sandia's Baseline 3 photovoltaic concentrator module (1988)

The design, fabrication, and testing of a photovoltaic concentrator module that can readily be adapted for commercial production are presented. It consists of a 2 by 12 parquet of lenses arranged with 24 cells in an aluminum housing. The cells are soldered directly to a copper heat spreader, eliminating the expensive ceramic wafer that has been used in previous designs. The aluminum housings are anodized and electrophoretically coated, with a high-temperature acrylic, creating a thin (50 mu m) electrically isolating layer capable of withstanding 3000 V. No additional electrical insulation between the electrically-live heat spreader and the housing is required, thereby enhancing heat transfer and, in combination with the copper heat spreader, eliminating the need for a separate heat sink.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Coulometric stripping potentiometry (1995)

Abstract The combination of a novel electrode design and a new experimental approach to coulometry permits the analysis of microliter amounts of samples without prior calibration. The technique has been applied to the determination of lead in whole blood standards. The time for one analysis is 4min and the relative precision approximately 5%. The mass detection limit for cadmium is 3 fmol, the lowest mass detection limit hitherto reported for any electroanalytical technique. The measurements are based on the principle of constant current stripping potentiometry. Amalgamated analytes are re‐oxidized by a Combination of an applied constant current and spontaneous chemical oxidation. Equations making it possible to apply Coulomb's law are presented.
Controlling the excited state charge transfer in DMABN using shaped femtosecond pulses (2007)

Enhancing effects of myristyl lactate and lauryl lactate on percutaneous absorption of indomethacin in rats. (1990)

The enhancing effects of myristyl lactate (ML) and lauryl lactate (LL) on the percutaneous absorption of indomethacin (ID) from test solutions in propylene glycol (PG) were investigated in rats. ID absorption was observed to be markedly enhanced by the addition of ML or LL to PG as compared with the control (PG alone). The marked enhancing effects were observed at concentrations greater than 3% ML and 3% LL in PG. In particular, the maximal enhancement of percutaneous absorption of ID was achieved at 5% ML and LL. To elucidate the mode of action of ML as an enhancer, the percutaneous absorption of ID through the skin pretreated with ML alone was investigated. It was suggested that ML acts on the stratum corneum to produce its effect.
The value of neopterin used in diagnosis and risk stratification of sepsis (2017)

Objective
To explore the value of neopterin (Np) in early diagnosis and risk stratification of sepsis.


Methods
A total of 82 patients admitted to the emergency department from April 2013 to February 2014 were enrolled in the study. They were divided into two groups: sepsis-free group (n= 8) and sepsis group (n=74). Patients' APACHE II scores were calculated within 24 hours after admission, and then their plasma levels of Np and procalcitonin (PCT) were detected and analysis was carried out to find the correlation between plasma levels of Np, PCT and acute physiology and chronic health evaluation Ⅱ score (APACHE Ⅱ score) in two groups. And 74 patients in sepsis group were further divided into three subgroups according to their APACHE Ⅱ score : Ⅰ subgroup (score ﹤ 15 , n= 27), Ⅱ subgroup (score 15 to 24 , n=32), and Ⅲ subgroup (score > 25 or more, n= 15). The differences in plasma Np and PCT levels were compared among three subgroups and correlation analysis of Np levels with PCT levels and APACHE Ⅱ scores was carried out.


Results
The plasma levels of Np, PCT and APACHE Ⅱ scores in sepsis group were higher than those in sepsis-free group (P<0.05). In sepsis group, the plasma levels of Np and PCT were gradually increased with the increasing severity of sepsis (P<0.05); In sepsis group, the plasma levels of Np, PCT and APACHE Ⅱ scores were positively correlated (P<0.01). The area under receiver operating characteristic curve (ROC) of Np was 0.79 and the area under ROC of PCT was 0.75, both of which had high diagnostic accuracy.


Conclusions
Neopterin has greatly useful value in early diagnosis and risk stratification of sepsis.

[What do people know about and expect from nurses?]. (1999)

The purpose of the present study was to learn about people's opinions on nurses' performance and on what do they expect from it. Authors interviewed patients and their families in Health Institutions and people walking in malls at the cities of Ribeirão Preto (125) and Bauru (125). The interviews were recorded, transcribed and analyzed. Results showed that the nurse is recognized as the one who is responsible for the care but there is still a representation of nurses as the doctor's helper. They refer to the nurse as someone courageous, important and on whom they depend on. They look for human care, dedication, respect, responsibility, understanding, affection and efficiency. They enable nurses' work and recognize the lack of better work conditions and fair wages.
Impacts of VIIRS polarization sensitivity on non-ocean scenes (2015)

The Visible and Infrared Imaging Radiometer Suite (VIIRS) collects Earth science data continually in a sun-synchronous orbit. VIIRS raw data records (RDRs) are processed by ground software to generate a variety of environmental data records (EDRs). Over open ocean, ground software produces measurements of chlorophyll concentration based on subsurface reflectance estimates. Considering that about 90% of the top of the atmosphere (TOA) radiance reaching a sensor over open ocean can be attributed to atmosphere or surface reflectance, it is possible to introduce large chlorophyll estimate errors by ignoring ordinarily small contributions due to polarization sensitivity. For chlorophyll determination, instrument polarization sensitivity measurements are used in combination with atmospheric models to compensate for polarization phenomenon. VIIRS ground software does not compensate for polarization phenomenon when processing land scenes. It is therefore natural to consider the impacts of ignoring VIIRS polarization phenomenon for land surface reflectance estimates. In this work, pre-flight polarization sensitivity characterization data is used in conjunction with a polarized atmospheric propagation model to analyze potential impacts on retrieved TOA reflectance. Impacts are analyzed across several collection conditions, including ground surface type, atmospheric visibility, general atmospheric profile and collection geometry. Actual pre-flight characterization data is used for both NPP and J1 VIIRS.
Cyclopentane-1,3-dione: A Novel Isostere for the Carboxylic Acid Functional Group. Application to the Design of Potent Thromboxane (A2) Receptor Antagonists (2011)

Cyclopentane-1,3-diones are known to exhibit pK(a) values typically in the range of carboxylic acids. To explore the potential of the cyclopentane-1,3-dione unit as a carboxylic acid isostere, the physical-chemical properties of representative congeners were examined and compared with similar derivatives bearing carboxylic acid or tetrazole residues. These studies suggest that cyclopentane-1,3-diones may effectively substitute for the carboxylic acid functional group. To demonstrate the use of the cyclopentane-1,3-dione isostere in drug design, derivatives of a known thromboxane A(2) prostanoid (TP) receptor antagonist, 3-(3-(2-(4-chlorophenylsulfonamido)ethyl)phenyl)propanoic acid (12), were synthesized and evaluated in both functional and radioligand-binding assays. A series of mono- and disubstituted cyclopentane-1,3-dione derivatives (41-45) were identified that exhibit nanomolar IC(50) and K(d) values similar to 12. Collectively, these studies demonstrate that the cyclopentane-1,3-dione moiety comprises a novel isostere of the carboxylic acid functional group. Given the combination of the relatively strong acidity, tunable lipophilicity, and versatility of the structure, the cyclopentane-1,3-dione moiety may constitute a valuable addition to the palette of carboxylic acid isosteres.
Some gallium phosphate frameworks related to the aluminium phosphate molecular sieves: X-ray structural characterization of {(Pr<sup>i</sup>NH<sub>3</sub>)[Ga<sub>4</sub>(PO<sub>4</sub>)<sub>4</sub>·OH]}·H<sub>2</sub>O (1985)

Several galliophosphate frameworks have been synthesised; some of the structures are related to the AlPO4-family of molecular sieves and the structure of {(PriNH3)[Ga4(PO4)4·OH]}·H2O has been shown to be related to AlPO4-12,-15, and -21.
Inverse modeling and its application in the design of high electron mobility transistors (1995)

An inverse modeling technique is introduced to determine the structural and physical parameters of HEMT from the desired data for maximum transconductance. The technique is based on the availability of analytical expressions describing the electron carrier concentration, the current, the transconductance, the capacitances and the unity current gain frequency of a HEMT. Empirical formulae are obtained that relate the maximum transconductance to the doped AlGaAs thickness, spacer layer thickness, dopant density and aluminum mole fraction. The technique is applied to the design of a HEMT and shows good agreement with the experimental data.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Failure of monotherapy in primary monosymptomatic enuresis: a combined desmopressin and propiverine treatment regimen improves efficacy outcomes (2008)

Re-evaluation of patients after monotherapy has failed is justified, because other entities can be discovered in patients so far treated unsuccessfully for enuresis. The combination of propiverine and desmopressin is highly effective in children with PME. Our results support the case for further optimizing the inaugurated treatment algorithm of PME for treatment duration, dose-titration and structured withdrawal programmes, thus possibly further decreasing relapse rates.
[A case of mitral regurgitation caused by necrosis and total rupture of the papillary muscle]. (1990)

Mitral regurgitation (MR) caused by total rupture of the papillary muscle has so ominous prognosis that it is treated by surgery exceedingly rarely. We recently experienced a case of MR caused by total rupture of the posterior papillary muscle that had presumably occurred after myocardial infarction. The patient was a 52-year-old male who was admitted to a hospital with liver dysfunction where he was noticed for the first time of his having cardiac murmurs and was diagnosed as having MR on the basis of echocardiography. With this diagnosis he was transferred to our department. Examination on admission revealed the patient to have an NYHA class III mitral incompetence with ECG evidence of old posteroinferior myocardial infarction. Cardiac catheterization demonstrated total occlusion of the segment 1 of the right coronary artery and MR, Sellers III. Abnormal echoes were noted in the left ventricle that moved almost synchronously with the posterior leaflet of the mitral valve, a finding leading to a suspected diagnosis of rupture of the posterior papillary muscle or chordae tendineae. Intraoperative findings were confirmative of total rupture of the posterior papillary muscle and mitral valve replacement was performed using a SJM prosthetic valve. Histological examination of the ruptured muscle revealed presence of necrosis, but no other specific inflammatory changes. Documented cases of surgically treated total papillary muscle rupture are quite limited in number, the present case being the 4th to be reported in Japan.
Direct determination of free thyroxin in undiluted serum by equilibrium dialysis/radioimmunoassay. (1988)

We have designed a re-usable dialysis cell and a complex dialysis buffer, with which undiluted serum samples can be dialyzed with minimal changes in their serum matrix. Dialysate thyroxin (free T4) is then measured by a sensitive RIA for T4. The range of reportability was 2-128 ng/L, the normal range was 8-27 ng/L, and the interassay CV was 7%. Free T4 concentrations in various disorders were as follows: hyperthyroidism, 32-478 ng/L; in both excess thyroxin-binding globulin (TBG) and familial dysalbuminemic hyperthyroxinemia, 9-27 ng/L; primary hypothyroidism, less than 2-7 ng/L; central hypothyroidism, 4-6 ng/L; severe TBG deficiency, 9-25 ng/L; hypothyroxinemias of nonthyroidal illness, 8-35 ng/L. With this free-T4 assay, which is adaptable to clinical laboratory use, one can differentiate hyperthyroidism from the major euthyroid hyperthyroxinemias and hypothyroidism from the major euthyroid hypothyroxinemias.
Macromolecular self-organized assemblies (1988)

Macromolecular assemblies can be self-organized into patterns with controllable feature sizes ranging from ∼10 Å to ∼100 μm. Smallest features are produced by organizing macromolecules into a Langmuir–Blodgett film. Using this method, we have produced quasiperiodic arrays of metal oxide islands with peroidicities as small as 9 Å. Larger (20–200 Å) extremely monodisperse features can be obtained by causing single polymer chains to self-organize into a coiled spherical ball on the surface of a substrate. By using narrow molecular weight distribution polymer chains, the standard deviation of the ball diameter can be made as small as ∼8 Å. The largest features produced come from self-organization in the assemblage of macromolecular colloidal particles (natural lithography). A wide variety of geometrical packing arrangements can be produced by controlling methods used to coat colloidal particles into a substrate. In particular, the use of surface textures to induce a form of graphoepitaxy in colloidal particle packing is discussed.
Acetylene mit Elektronendonator und Elektronenakzeptorgruppen (1969)

Abstract Acetylenes having both electrondonating and electronaccepting groups ( 1 ) may be obtained in good yield from the correspondingly substituted olefines via bromination and elimination of HBr. The reaction of the acetylene aldehyde 1a with proton acids yields, after rearrangement of the primary adducts, the β‐substituted acrylamides. Addition of nucleophiles leads to the β‐disubstituted α.β‐unsaturated carbonyl compounds. With hydrazines one obtains pyrazoles and pyrazolones. The acetylenes 1 undergo [2+2]‐, [2+3]‐ and [2+4]‐cycloaddition reactions.
[A telemedical multilevel server network system]. (2001)

Telemedicine is a hot research focus. When we develop the telemedicine system, we find that in China the network condition can not fit the demands of the transregional telemedicine service. In order to improve the poor conditions, we have designed a set of telemedicine system based on distributed multilevel server network model. The paper expounds the structure and the working process of the system, then goes into the technology details in realizing it, finally discusses some relative questions.
