Electronic excitations of benzene from the equations of motion method

We have used the equations of motion method to calculate the excitation energies and intensities of several transitions in benzene. The ordering of the singlet and triplet states of B_(2u), B_(1u), and E_(1u) symmetry agrees with experiment and the error in the calculated frequencies ranges from 3% to 25%. This error range is reasonable considering the relatively small basis set used. The most extensive calculation included 10 hole and 28 particle states and shows the effect of changes in the sigma core for each transition. The calculated transition moment of 1.74 a.u. for the ^1A_(1g)→^1E_(1u) transition agrees well with the experimental value of 1.61 a.u

High resolution Doppler lidar

A high resolution lidar system was implemented to measure winds in the lower atmosphere. The wind speed along the line of sight was determined by measuring the Doppler shift of the aerosol backscattered laser signal. The system in its present configuration is stable, and behaves as indicated by theoretical simulations. This system was built to demonstrate the capabilities of the detector system as a prototype for a spaceborne lidar. The detector system investigated consisted of a plane Fabry-Perot etalon, and a 12-ring anode detector. This system is generically similar to the Fabry-Perot interferometer developed for passive wind measurements on board the Dynamics Explorer satellite. That this detector system performs well in a lidar configuration was demonstrated

Alignment of the Holy Cross College STA. Rosa Student’s Program with their Interest and Skills

There are several elements that impact individuals' college program selection. Most students choose their college program based on parental influence, often overlooking some aspects such as whether they are fit or interested in the programs. This research focused on finding if there’s a significant relationship between the alignment of students’ programs with their interests and skills to their academic performance. The test was conducted on the 3rd-year students of Holy Cross College enrolled in the year 2021-2022. The researchers conducted the survey on the selected programs of Holy Cross College which is from the Education, Computer Science, Business Management, and Hospitality Management. This study used a quantitative, non-experimental design using a correlational approach. Spearman Rank Correlation, a non-parametric test was used to find the relationships between the alignment of the students and their academic performance. In testing the alignment of the students, the researchers used the Holland Theory. The data show that the obtained value is rs = -0.004 and the critical value is set at 0.206. Failure to pass certain criteria we fail to reject our null hypothesis (rs = -0.004, ρ>0.05). Therefore, we can say that there is no significant relationship between the alignment of students’ programs with their skills and interests, and performance. Whether the student’s programs are aligned or not aligned with their interest and skills they can still have good performance in their chosen programs. Although from the data obtained we can notice that students aligned with their programs have better performance academically

How best to diagnose asthma in infants and toddlers?

No reliable way exists to diagnose asthma in infants and toddlers. Recurrent wheezing, especially apart from colds, combined with physician diagnosed eczema or atopic dermatitis, eosinophilia, and a parental history of asthma, increase the probability of a subsequent asthma diagnosis in the absence of other causes (strength of recommendation: B, 2 good-quality cohort studies)

Microbial ecology of the murine gut associated with the development of dextran sodium sulfate-induced colitis

Background: Dextran sodium sulfate (DSS) is used to induce murine colitis. Although the exact mechanism by which DSS administration causes disease is unknown, evidence suggests that the resident bacteria play a role in the development of murine DSS colitis, analogous to their role in human inflammatory bowel diseases. Methods: C57BL/6 mice received 5% DSS in the drinking water and were euthanized 3 days and 14 days after the initiation of DSS treatment. Culture-independent methods were used to follow changes in the community structure of the gut's microbiota following DSS treatment. Histologic evidence of disease and changes in host gene expression were assessed. Results: Histologic colitis was minimal in DSS-treated animals at 3 days, but severe after 14 days. Analysis of 16S rRNA-encoding gene clone libraries demonstrated that the microbial communities in the ceca of DSS-treated mice were distinct from those in control mice. The microbiota in the cecum of DSS-treated animals was characterized by an overall decrease in microbial richness, an increase in members of the phylum Verrucomicrobia, and decrease in Tenericutes. Changes in the host's inflammatory response and microbial communities occurred before the histologic appearance of severe disease in the colon, but were seen concurrently in the cecum. Conclusions: DSS administration is associated with reproducible changes in the gut microbial diversity of mice. Microbial and immunological changes appeared before the development of severe inflammation in the colon. This indicates that these changes in microbial community may play role in the potentiation of the abnormal inflammatory response seen in DSS-treated animals.

What are the benefits and risks of inhaled corticosteroids for COPD?

Q: What are the benefits and risks of inhaled corticosteroids for COPD? A: Inhaled corticosteroids (ICS), either alone or with a long-acting [beta] agonist (LABA), reduce the frequency of exacerbations of chronic obstructive pulmonary disease (COPD) and statistically, but not clinically, improve quality of life (QOL) (strength of recommendation [SOR]: B, meta-analyses of heterogeneous studies). However, ICS have no mortality benefit and don't consistently improve forced expiratory volume in 1 second (FEV1) (SOR: B, meta-analyses of secondary outcomes). They increase the risk of pneumonia, oropharyngeal candidiasis, and bruising (SOR: B, meta-analyses of secondary outcomes). Withdrawal of ICS doesn't significantly increase the risk of COPD exacerbation (SOR: B, a meta-analysis)

Applicability of SCF Theory to Some Open-Shell States of CO, N2, and O2

By working with the real functions pix and piy instead of pi+ and pi–, we show how to express the SCF Hamiltonians for the Sigma states of the configurations (piu)3(pig),(piu)3(pig)3, and (1pi)3 (2pi) of diatomic molecules in terms of the Coulomb and exchange operators only. With these results, we have used conventional SCF programs to solve for the wavefunctions of many interesting states of N2, O2, and CO, e.g., the B 3Sigmau– state of O2. For many states, the SCF results are in good agreement with experiment. However, SCF theory runs into serious trouble if electron correlation is important in determining the relative locations of excited states

Prediction of recurrent Clostridium difficile infection using comprehensive electronic medical records in an integrated healthcare delivery system

BACKGROUNDPredicting recurrentClostridium difficileinfection (rCDI) remains difficult. METHODS. We employed a retrospective cohort design. Granular electronic medical record (EMR) data had been collected from patients hospitalized at 21 Kaiser Permanente Northern California hospitals. The derivation dataset (2007–2013) included data from 9,386 patients who experienced incident CDI (iCDI) and 1,311 who experienced their first CDI recurrences (rCDI). The validation dataset (2014) included data from 1,865 patients who experienced incident CDI and 144 who experienced rCDI. Using multiple techniques, including machine learning, we evaluated more than 150 potential predictors. Our final analyses evaluated 3 models with varying degrees of complexity and 1 previously published model.RESULTSDespite having a large multicenter cohort and access to granular EMR data (eg, vital signs, and laboratory test results), none of the models discriminated well (c statistics, 0.591–0.605), had good calibration, or had good explanatory power.CONCLUSIONSOur ability to predict rCDI remains limited. Given currently available EMR technology, improvements in prediction will require incorporating new variables because currently available data elements lack adequate explanatory power.Infect Control Hosp Epidemiol2017;38:1196–1203</jats:sec

A backward glance of who and what marketing scholars have been researching 1977-2002

Despite the diversity of all those involved within the marketing discipline, all have a stake in maximizing the advancement of marketing knowledge. Without a specific analysis it is difficult to reflect on where a field has been or where it might be heading. The purpose of this chapter is to examine who and what marketing scholars have been researching over the period 1977&ndash;2002 using content analysis. This chapter provides longitudinal benchmarking of the &lsquo;&lsquo;inputs&rsquo;&rsquo; (authors and institutions) and &lsquo;&lsquo;outputs&rsquo;&rsquo; (articles) examining the marketing literature in the four major marketing journals: the Journal of Marketing, the Journal of Marketing Research, the Journal of Consumer Research, and the Journal of the Academy of Marketing Science.<br /
