Some lessons from basic finance for effective socially responsible investing (1995)

Given the vast sums of money that mutual and pension fund managers invest, an important question is how they should go about deciding which assets, especially which stocks, they should purchase. One school of thought argues that investment policies should reflect some set of social values. This study examines three questions about the financial implications of effective socially responsible investing in common stocks--that is, socially responsible investment intended to change firms' behavior. ; The first question concerns what socially responsible investors can do to effectively influence firms' investment policies. The second question is, under what conditions, if any, will the securities markets permit effective socially responsible investment? Third, what impact will socially responsible investment have on the performance of portfolios that follow it? ; The analysis has two implications for fund managers and investors who want to change firms' behavior. The first is that the investment strategy should focus on buying shares of small socially responsive firms. The second is that investors who owned targeted socially responsible stocks before socially responsible investment began will realize above-market rates of return in the short run; however, once socially responsible investors stop bidding up the price, investors will receive reduced returns.
Error correction for video streaming to enhance MPEG performance quality (2015)

For real-time transmission, still image and video sources require wide bandwidths and large storage memory space. Therefore, compression techniques are useful and must be applied to overcome the load variation problem during the transmission and storage. To reconstruct images or video from compressed data without any disruption or losses, two important objective image quality metrics, the peak-signal-to-noise ratio (PSNR) as well as the structural similarity index measure (SSIM) will be used. PSNR value increased and approaches infinity as the Mean Square Error (MSE) approaches zero; thus a higher image quality resulted from a higher PSNR value and a lower value of MSE. At the other end of scale, a higher numerical differences between images resulted from a small value of PSNR and a large value of MSE[1]. The SSIM is the other quality metric which used to measure the similarity between two images. The paper simulates a real channel with a protection signal to noise ratio (snr), and take into account the Group of Pictures (GoP) structure. Also, the paper studies the impact of a real noise which generated to reconstruct the modulated video with a lower size to safe in storage and an optimal resolution to reach the suitable quality. The simulation results show that the Quadrature Amplitude Modulation is the best modulation in terms of the performance of video streaming and sending image over wireless channel. To increase the performance, a constrained Reed Solomon Protection technique can be used, by increasing redundancies bits the performance increase but the delay also increased.
A temperature-chlorinity-depth recorder for use at sea (1958)

An instrument for recording temperature, chlorinity and depth in the upper 1000 metres of the sea is described. The temperature range is 0-30° C, with an accuracy of ±0 15° C. The chlorinity range spans about seven parts per thousand of chlorinity, the accuracy being ±0.03 parts per thousand. The accuracy in depth is ±10 m. The three quantities are recorded sequentially by a single-pen strip-chart recorder, each quantity being recorded for five seconds at a time. The underwater unit is suspended by means of an armoured steel cable, which has a single electrically-insulated core. This core carries power down to the underwater unit, and brings up the signals from the measuring elements. A simple frequency-modulation method of telemetering is used.
Active removal of wind noise from outdoor microphones using local velocity measurements (1998)

Wind noise in outdoor microphone measurements can significantly degrade acoustic data. An outdoor active windscreen based upon four local anemometer velocity measurements applied to an unscreened microphone is demonstrated. A simple relationship, developed from the Bernoulli equation, is used to transform hot-film anemometer wind velocity measurements into microphone wind pressure estimates. Measurements performed outdoors on a horizontally positioned microphone demonstrate that a major part of unscreened microphone wind noise is flow noise caused by interaction between the microphone and adjacent air flow. These measurements also indicate that the dominant source of wind noise in a passively screened microphone are local pressure fluctuations that are not correlated with local velocity fluctuations. This important observation indicates that the active windscreen is unlikely to significantly quiet a microphone that has conventional passive screening and that the active windscreen applied to an unscreened microphone is unlikely to surpass the performance of a passive windscreen. Wind energy reduction performance of the active windscreen is shown to be approximately 12 dB for frequencies below 200 Hz and decreases smoothly to approximately 5 dB at 500 Hz. In addition, the active system transfer functions are observed to possess significant stability of over periods of hours. a)Currently at Texas Instruments. b)Currently at California Maritime Academy.

A new horizontal collision detection scheme for avatar with avatar in collaborative virtual environment (2005)

To guarantee collision-free locomotion of avatar in collaborative virtual environment, a collision detection scheme should be provided to prevent avatar from not only penetrating into all other virtual obstacles but also colliding with all other avatars without stalling any avatar with ultimate goal of user's senses of presence, reality and immersion. This paper discussed how to design a horizontal collision detection scheme for avatar with avatar. First, it proposed several design considerations for a horizontal collision detection scheme. Second, through collision precaution and collision repulsive field that are two attached properties to avatars, the process procedure of the whole collision detection is divided into three processes: collision determination, collision avoidance and path amendment. On the basis of above works, this paper presented a new horizontal collision detection scheme AACD for avatar with avatar in collaborative virtual environment. Finally, architecture of AACD is described in details in this paper.
A Condition for Stable Minimum-Bandwidth Line Codes (1985)

By generalizing a concept on a power spectral zero at the Nyquist frequency, a condition for the line codes' capability to signal with the minimum bandwidth is established. From the condition, lower bounds of eyewidth are obtained for various values of a new system parameter called intersymbol interference sum variation (ISV). As an application of the condition, the nonminimum-bandwidth bipolar code is modified to a minimum-bandwidth code, which can be directly used in conventional bipolar signaling systems with increased bandwidth efficiency.
Risk of acute myocardial infarction with real‐world <scp>NSAID</scp>s depends on dose and timing of exposure (2017)

Weighted cumulative exposure analysis uncovered NSAID-specific differences in the immediate MI risk and how this risk seems to accumulate. KEY POINTS Accurate assessment of drug safety requires an etiologically correct model encompassing all relevant aspects of exposure. Weighted cumulative exposure models suggest that the relative importance of past doses on the risk of MI differs among NSAIDs. All common NSAIDs are associated with an increased MI risk. Celecoxib MI risk seems to depend on continuously using the drug for more than 30 days, whereas for ibuprofen, rofecoxib, diclofenac, and naproxen, a heightened MI risk occurs within 7 days of use.
Human protein C and activated protein C (1995)

Protein C, the zymogen form of the anticoagulant protein, activated protein C, is a member of the vitamin K-dependent class of proteins that function in generation and control of formation of blood clots. This plasma protein consists of a series of domain regions that are qualitatively similar to those present in human coagulation factors VII, IX, and X, and that appear to be related to specific properties of these proteins. With the recent advent of rigorous application of genetic engineering strategies to this system, and the continuing discoveries and characterization of genotypes and phenotypes of protein C in patients, great progress has been made in understanding structure-function relationships of protein C and activated protein C. This review is a summary and synthesis of recent pertinent studies with an emphasis on these topics.
Mechanical Properties of Adult Vertebral Cancellous Bone: Correlation With Collagen Intermolecular Cross‐Links (2002)

Although the mechanical strength of cancellous bone is well known to depend on its apparent density, little is known about the influence of other structural or biochemical parameters. This study specifically investigates the cross-linking of the collagen in human vertebral bone samples and its potential influence on their mechanical behavior. Multiple cylindrical samples were cored vertically in the vertebral bodies of nine subjects (aged 44-88 years). Three spinal levels (T9, T12 or L1, and L4) and three sample sites within a vertebral body (anterior, posterior, and lateral) were used, for a total of 68 samples. The density was measured with peripheral quantitative computed tomography (pQCT) and all cylinders were mechanically tested in compression. After mechanical testing, they were unmounted and used for biochemical analysis. The amount of collagen (wt/wt of bone) and its content in reduced immature cross-links, that is, hydroxylysinonorleucine (HLNL, mol/mol of collagen) and dihydroxylysinornorleucine (DHLNL), as well as stable mature cross-links, that is, hydroxylysyl-pyridinoline (HP), lysyl-pyridinoline (LP), and pyrrole cross-link were determined for each cylinder. None of the biochemical parameters correlated to the density. On multiple linear regression, the prediction of the mechanical properties was improved by combining density data with direct collagen cross-link assessment. The HP/LP ratio appeared as a significant predictor to the strength (r = 0.40; p = 0.001) and stiffness (r = 0.47; p < 0.001) samples with a high HP/LP ratio being stronger and stiffer. Additionally, the ultimate strain correlated to the HP or LP concentration (r = 0.38 or 0.49; p < 0.01). Different subjects had different HP/LP ratios and different HP or LP concentrations in their vertebral bone samples, and the location of origin within a subject had no influence on the concentration. These observations suggest that the nature of the organic matrix in adult vertebral bone is variable and that these variations influence its mechanical competence.
Anthocyanins and flavones in leaves and seeds of Perilla plant. (1981)

Sixteen kinds of flavonoids including five anthocyanins, two flavones and nine flavone glycosides were found to be present in mature dark-red leaves and seeds of Perilla frutescens var. crispa. In seeds, apigenin and luteolin were present in a ratio of about 1 : 1. Both flavones and nine flavone glycosides were found in the leaves. In addition, the leaves contained five kinds of anthocyanins including cyanidin 3, 5-diglucoside and its esters with cinnamic acid derivatives. Amongthese flavonoids, the 3-p-coumarylglucoside-5-glucoside of cyanidin (shisonin) and the 7-caffeylglucosides of apigenin and luteolin were the major component in the leaves.
Drill Biopsy Confirmation of Breast Cancer (1976)

The technique of drill biopsy of suspicious masses in the breast has been used in 135 patients, with 98.5% accuracy. It has permitted discrimination in the application of expensive scanning studies. Prior confirmation of the diagnosis of carcinoma reduces operating room and anesthesia time, and eliminates the need for two sets of instruments.
United States Department of Veterans Affairs Chiropractic Services Pilot Program evaluation study SDR #86-09: a critique. (1993)

The following critique of the Chiropractic Services Pilot Program (SDR #86-09) focuses on two major issues: the terms of reference established for the study and the research constraints that arose from either the terms of reference or their interpretation; the technical design and execution of the research. The review suggests that the constraints invalidated the study and ensured that no comparisons are possible between chiropractic and medical care for VA patients based on these results. The constraints resulted in the use of a nonexperimental design, distinct samples being chosen and nonequivalent care settings being compared. The critique also reveals that in each of the design steps (eligibility criteria, sampling, protocols, data collection, analysis, interpretations) there were serious methodological flaws. These ensured that the two populations being compared (chiropractic patients versus medical patients) were in fact noncomparable. In terms of the economic cost comparisons, the design guaranteed the comparison was unfair, pitting a private, fee-for-service chiropractic practice against a not-for-profit, managed-care, federally regulated and budgeted institution. Furthermore, the allocation of costs to the two groups was done inaccurately. The critique concludes that the results are not valid, they cannot be used for generalizing, they cannot be used for statistical analysis and they should not be used to establish policy. The research design and the methodological flaws meant that the objectives of the study could not be met.
[Isolation and physico-chemical properties of a protein, included in an endotoxin from Yersinia pseudotuberculosis]. (1989)

A major protein of the endotoxin from Yersinia pseudotuberculosis was isolated from the complex lipid A--protein by treatment with SDS and triton X-100 followed by gel-chromatography on Sephacryl S-300. Protein has apparent molecular mass 40 kDa and alanine as N-terminal amino acid residue. CD and IR spectroscopy conformational changes of the protein molecule in the process of its isolation. The thermal and pH stabilities of the protein were investigated by the methods of intrinsic fluorescence and differential scanning microcalorimetry. The isolated protein revealed two thermal transitions (at 30-35 and 50-55 degrees C), which depend on Ca2+ concentration.

Formal callability and its relevance and application to interprocedural data-flow analysis (2002)

Formal callability is the problem of determining for every formal procedure call of a program the set of procedures it may call at run-time. This information is the key for constructing the procedure call graph of a program, a common prerequisite of static analyses of programs with procedures. Moreover, under specific side-conditions it reduces in interprocedural data-flow analysis the analysis of programs with formal procedure calls to the analyses of programs without formal calls by treating formal calls as higher-order branch statements. The author demonstrates that formal callability yields as a by-product the solution of the well-known formal reachability problem. This directly implies that formal callability is in general not decidable. However, the author shows that formal callability is decidable for programs, where formal procedure parameters do not occur in procedures, which are local to the procedure of their declaration (usually known as programs without global (formal) procedure parameters), but within a time bound which is exponential in the program size. Thus, the author complements the new decidability result by introducing in addition a safe approximation of formal callability called potential passability, which can efficiently be computed. Moreover, for programs of mode depth 2 (i.e., formal procedures do not have procedures as parameters) without global procedure parameters, formal callability and potential passability coincide.
Nucleotide sequence of an insertion element, IS1. (1978)

PSM2, PSM1, and PSM15 are small plasmids derived from R100 by spontaneous deletions at either end of the insertion sequence IS1. These plasmids were used to identify regions neighboring IS1 as well as the IS1 DNA itself, by cleavage with EcoR1, HindIII, Hae III, Hpa II, Hha I, Hinf, and AIu I. The nucleotide sequencing results demonstrate that IS1 contains 768 bases. About 30 bases at the ends of IS1 were found to be repeated in an inverted order. The deletions occurring at the ends of IS1 were found to be due to illegitimate recombination. The hypothesis that RNA polymerase could play an important role in such recombination phenomena is discussed based on the nucleotide sequences surrounding the recombinational hot spots.
Quantitative EEG methods and measures in human psychopharmacological research (2000)

The quantitative analysis of electroencephalographic (EEG) signals is an established methodology for objectively describing the central impact of drugs administered to human subjects. This paper outlays the essential objectives and findings of this electrophysiologic measurement model of drug action and addresses the subject, recording, analytical and statistical standards which are required to ensure valid pharmaco-EEG profiling.

Design, implementation, and performance evaluation of MPI 3.0 on portals 4.0 (2013)

The latest version of the Portals interconnect programming interface contains several improvements intended for MPI point-to-point and one-sided communication operations, including new functionality defined in MPI-3. This paper discusses the rationale for these improvements to Portals and describes how they can be used in an MPI implementation. We provide preliminary micro-benchmark performance results using a reference implementation of Portals over InfiniBand Verbs and the Open MPI implementation.
Assessing the adequacy of documentation through document quality indicators (2003)

Case study results for a research effort funded by the US Naval Surface Warfare Center (NSWC) are presented. The investigation focuses on assessing the adequacy of project documentation based on an identified taxonomic structure relating documentation characteristics. Previous research in this area has been limited to the study of isolated characteristics of documentation and English prose, without considering the collective contributions of such characteristics. The research described takes those characteristics, adds others and establishes a well-defined approach to assessing the 'goodness' of software documentation. The identification of document quality indicators (DQIs) provides the basis for the assessment procedure. DQIs are hierarchically defined in terms of document qualities, factors that refine qualities, and quantifiers that provide for the measurement of factors.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
A regulatory switch involving a Clp atpase (1997)

Clp ATPase chaperone proteins are found in procaryotes and eucaryotes. Recently, ClpC of Bacillus subtilis was found to be part of a regulatory switch(1). ClpC, in combination with the MecA and ComS proteins, regulates the activity of a transcription factor, ComK, which is necessary for the development of genetic competence (the ability to bind and take up exogenous DNA). The complex of ClpC:MecA:ComK renders ComK inactive. Interaction between ComS and the ternary complex releases active ComK. This regulatory switch controls ComK activity in response to cell density signals that affect production of ComS. Regulated interaction between Clp ATPase and target proteins might prove to be widespread.

Effect of NF-κB inhibitors on the chemotherapy-induced apoptosis of the colon cancer cell line HT-29 (2012)

This study aimed to investigate the impact of the combined use of the nuclear factor-κB (NF-κB) inhibitors pyrrolidine dithiocarbamate (PDTC), bortezomib or SN50, and the chemotherapy agents arsenic acid (As(2)O(3)), fluorouracil (5FU), oxaliplatin or paclitaxel on the growth and apoptosis of HT-29 cells. Cell morphology was observed using inverted microscopy, and cell viability and apoptosis were assessed using the MTT assay and flow cytometry, respectively. The activities of NF-κB were analyzed by western blotting and electrophoretic mobility shift assay (EMSA). Cell growth was significantly inhibited by As(2)O(3), oxaliplatin and paclitaxel in a time- and concentration-dependent manner (P<0.05), while 5FU inhibited cell growth in a time-dependent manner only (P<0.05). The growth inhibition rate and apoptosis induction ratio were increased following the combined treatment of the chemotherapy agent and NF-κB inhibitor. The expression of NF-κB p65 was upregulated when cells were treated with a chemotherapy drug, however it was downregulated following combined treatment or treatment with an NF-κB inhibitor alone. In conclusion, an NF-κB inhibitor combined with a chemotherapy drug effectively inhibited cell proliferation, induced cell apoptosis and inhibited NF-κB activity to enhance the chemotherapeutic sensitivity of HT-29 cells.
Transmission line pilot protection based on phase segregated model recognition (2009)

A new type of transmission line pilot protection based on phase segregated model recognition is presented, since the capacitance model and the inductance model are established, respectively, for the external fault and the internal fault. When the internal fault occurs, the capacitance model error is larger than the inductance model error. When the external fault occurs, the inductance model error is larger than the capacitance model error. By computing the model error, the actual state of transmission lines is obtained. Theoretical analysis and electromagnetic transients program (EMTP) simulation demonstrate that this novel protection principle is unnecessary to compensate the distribution capacitance current and has fast operation speed and good performance on resisting transition resistance and transient components.
