An excited-state approach within full configuration interaction quantum Monte Carlo.

We present a new approach to calculate excited states with the full configuration interaction quantum Monte Carlo (FCIQMC) method. The approach uses a Gram-Schmidt procedure, instantaneously applied to the stochastically evolving distributions of walkers, to orthogonalize higher energy states against lower energy ones. It can thus be used to study several of the lowest-energy states of a system within the same symmetry. This additional step is particularly simple and computationally inexpensive, requiring only a small change to the underlying FCIQMC algorithm. No trial wave functions or partitioning of the space is needed. The approach should allow excited states to be studied for systems similar to those accessible to the ground-state method due to a comparable computational cost. As a first application, we consider the carbon dimer in basis sets up to quadruple-zeta quality and compare to existing results where available.N.S.B. gratefully acknowledges Trinity College, Cambridge for funding.

Typhoid fever is one of the diseases of the digestive that is caused by the salmonella typhi and characterized by a rise in body temperature or fever. Compress is one of the measures to decrease the production of heat and heat increase spending. The purpose of this research is viewed comparison of effectiveness between tepid sponge compress and warm water compress against a decrease in body temperature. Types of quantitative research, research design used was a quasi experimental design with pretest-posttest two group treatment. Sample research amounted to 38 respondents, then divided in two groups of treatment tepid sponge compress and warm water compress so that each group of 19 respondents, treatment was given for 15 minutes. Statistical analysis using the T-Test test : Paired Sample T-Test to analyze the pre-test and post-test both treatment groups and Independent Sample T-Test to analyze the effectiveness of the comparison between the two treatment groups.

Semi-stochastic full configuration interaction quantum Monte Carlo: Developments and application.

We expand upon the recent semi-stochastic adaptation to full configuration interaction quantum Monte Carlo (FCIQMC). We present an alternate method for generating the deterministic space without a priori knowledge of the wave function and present stochastic efficiencies for a variety of both molecular and lattice systems. The algorithmic details of an efficient semi-stochastic implementation are presented, with particular consideration given to the effect that the adaptation has on parallel performance in FCIQMC. We further demonstrate the benefit for calculation of reduced density matrices in FCIQMC through replica sampling, where the semi-stochastic adaptation seems to have even larger efficiency gains. We then combine these ideas to produce explicitly correlated corrected FCIQMC energies for the beryllium dimer, for which stochastic errors on the order of wavenumber accuracy are achievable.N.S.B. gratefully acknowledges Trinity College, Cambridge for funding.

Unbiased reduced density matrices and electronic properties from full configuration interaction quantum Monte Carlo.

Properties that are necessarily formulated within pure (symmetric) expectation values are difficult to calculate for projector quantum Monte Carlo approaches, but are critical in order to compute many of the important observable properties of electronic systems. Here, we investigate an approach for the sampling of unbiased reduced density matrices within the full configuration interaction quantum Monte Carlo dynamic, which requires only small computational overheads. This is achieved via an independent replica population of walkers in the dynamic, sampled alongside the original population. The resulting reduced density matrices are free from systematic error (beyond those present via constraints on the dynamic itself) and can be used to compute a variety of expectation values and properties, with rapid convergence to an exact limit. A quasi-variational energy estimate derived from these density matrices is proposed as an accurate alternative to the projected estimator for multiconfigurational wavefunctions, while its variational property could potentially lend itself to accurate extrapolation approaches in larger systems

Prevalence and Correlates of Common Mental Disorders among Mothers of Young Children in Kilimanjaro Region of Tanzania.

Although poor maternal mental health is a major public health problem, with detrimental effects on the individual, her children and society, information on its correlates in low-income countries is sparse. This study investigates the prevalence of common mental disorders (CMD) among at-risk mothers, and explores its associations with sociodemographic factors. This population-based survey of mothers of children aged 0-36 months used the 14-item Shona Symptom Questionnaire (SSQ). Mothers whose response was "yes" to 8 or more items on the scale were defined as "at risk of CMD." Of the 1,922 mothers (15-48 years), 28.8% were at risk of CMD. Risk of CMD was associated with verbal abuse, physical abuse, a partner who did not help with the care of the child, being in a polygamous relationship, a partner with low levels of education, and a partner who smoked cigarettes. Cohabiting appeared to be protective. Taken together, our results indicate the significance of the quality of relations with one's partner in shaping maternal mental health. The high proportion of mothers who are at risk of CMD emphasizes the importance of developing evidence-based mental health programmes as part of the care package aimed at improving maternal well-being in Tanzania and other similar settings

Gambaran Kejadian Diare pada Bayi usia 0-24 bulan dengan Makanan Pendamping Air Susu Ibu Dini dan Tanpa Makanan Pendamping Air Susu Ibu dini Diwilayah kerja Puskesmas Jayengan Surakarta

Diarrhea is a disease that can affect children in particular, infants and toddlers are more susceptible to this disease. The incidence of diarrhea in toddlers is one of them caused by cleanliness, knowledge and attitudes of mothers in providing complementary breastfeeding. The purpose of this study was to describe the incidence of diarrhea in children aged 0-24 months with complementary ASI (MP ASI) food and without ASI (MP ASI) early. This type of research is descriptive with a number of samples of 47 respondents by means of sampling Accidental sampling and using analysis of data Frequency, the number of samples in this study were as many as 47 respondents. The results of the study were 25 children who suffered from diarrhea with MP ASI early. Of the 25 children, most had the frequency of getting diarrhea the same as or more than 3 times in the last 3 months as many as 17 children, and 8 children had a frequency of less than 3 times. And 22 children who suffer from diarrhea without MP early breastfeeding, most have the frequency of getting diarrhea less than 3 times in the last 3 months as many as 16 children, and 6 children have the same frequency or more than 3 times
