Generalized WDVV equations for B_r and C_r pure N=2 Super-Yang-Mills theory

A proof that the prepotential for pure N=2 Super-Yang-Mills theory associated with Lie algebras B_r and C_r satisfies the generalized WDVV (Witten-Dijkgraaf-Verlinde-Verlinde) system was given by Marshakov, Mironov and Morozov. Among other things, they use an associative algebra of holomorphic differentials. Later Ito and Yang used a different approach to try to accomplish the same result, but they encountered objects of which it is unclear whether they form structure constants of an associative algebra. We show by explicit calculation that these objects are none other than the structure constants of the algebra of holomorphic differentials.Comment: 8 page

Second order reductions of the WDVV Equations related to classical Lie algebras

We construct second order reductions of the generalized Witten-Dijkgraaf-Verlinde-Verlinde system based on simple Lie algebras. We discuss to what extent some of the symmetries of the WDVV system are preserved by the reduction.Comment: 6 pages, 1 tabl

Efficacy of Two Common Methods of Application of Residual Insecticide for Controlling the Asian Tiger Mosquito, Aedes albopictus (Skuse), in Urban Areas

After its first introduction in the 1980's the Asian tiger mosquito, Aedes albopictus (Skuse), has spread throughout Southern Europe. Ae. albopictus is considered an epidemiologically important vector for the transmission of many viral pathogens such as the yellow fever virus, dengue fever and Chikungunya fever, as well as several filarial nematodes such as Dirofilaria immitis or D. repens. It is therefore crucial to develop measures to reduce the risks of disease transmission by controlling the vector populations. The aim of the study was to compare the efficacy of two application techniques (mist vs. stretcher sprayer) and two insecticides (Etox based on the nonester pyrethroid Etofenprox vs. Microsin based on the pyrethroid type II Cypermetrin) in controlling adult tiger mosquito populations in highly populated areas. To test the effect of the two treatments pre- and post-treatment human landing rate counts were conducted for two years. After one day from the treatment we observed a 100% population decrease in mosquito abundance with both application methods and both insecticides. However, seven and 14 days after the application the stretcher sprayer showed larger population reductions than the mist sprayer. No effect of insecticide type after one day and 14 days was found, while Etox caused slightly higher population reduction than Microsin after seven days. Emergency measures to locally reduce the vector populations should adopt adulticide treatments using stretcher sprayers. However, more research is still needed to evaluate the potential negative effects of adulticide applications on non-target organisms

Hubungan Faktor Host (Umur 6 Bulan-14 Tahun) dan Keberadaan Vektor dengan Kejadian Demam Berdarah Dengue di Wilayah Kerja Puskesmas Kedungmundu Semarang Relationship Of Host Factors (Ages 6 Months - 14 Years) And Existence Vector With Dengue Hemorrhagic

Semarang city is endemic regions, with the highest incidence rate in the District Tembalang in 2014 (IR = 110.55 for 100.000 in population). Case of DHF in Kedungmundu Primary Health Service was just happen 2014 which amount 154 cases with 86% of cases in the age group of 6 months-14 years. The purpose of this study was to determine the relationship of host factors (age 6 months-14 years) and the existence of the vector with the incidence of DHF in Kedungmundu Primary Health Service Semarang. This type of research was quantitative with a case control approach. Total sample was 104 samples. Analysis of data using chi-square test. The results of this research showed that there were association using mosquito repellent (p=0.003), history of DHF illness (p=0.008), and the existence of larva (p=0.0001) with incidence of DHF. Meanwhile, there were no relationship habit of sleeping morning/noon (p=0.430), habit of sleeping afternoon (p=0.691), habit of hanging clothes (p=0.316), using of mosquito nets (p=0.339), and nutritional status (p=0.150) with incidence of DHF. It was advisable for the community to increase efforts to improve activities mosquito nest eradication (PSN), and for Kedungmundu Primary Health Service to increase efforts to control DHF, for example regular larva monitoring and thorough

Effect of Plectranthus Amboinicus Extract on BUN and Creatinine Levels and Cellular Response Proinflammatory Factors TNF-α and IL-1β on Gout Arthritis Patients

The purpose of this research was to develop anti-cytokine-based treatment using extract of Plectranthus amboinicus applied to gout arthritis (GA) patients. The research was quasi experimental, with a pretest-posttest randomized control group design. The samples were GA patientsin the Outpatient Installation of Internal Medicine in General Hospital Haji,Surabaya. The sample was comprised of 30 respondents. The respondents were divided into a treatment group and a control group. The treatment group was asked to take medicine from the hospital, coupled with Plectranthus amboinicus extract capsules, for 7 days, during which time patients’ joint inflammation was observed. The control group was provided with only medication from the hospital, and their joint inflammation was likewise observed. Blood samples were taken before and after treatment, to measure the levels of blood urea nitrogen (BUN) and creatinine, as well as the concentrations of TNF-α and IL-1β. There was a decrease in BUN and creatinine levels in the control group, but it was not significant, decreasing by 3% and 8%, respectively. The treatment group also showed elevated levels of BUN and creatinine, which also was not significant at 3% and 7%, respectively. There was a decrease in the concentration of TNF-α in the control group by 9% and 22%. The concentration of IL-1β in the control group increased by 18%, whereas,in the treatment group,it decreased by3%; however,the decreases in bothgroups were not significant

Pengaruh Variasi Kepadatan Pupa Aedes Aegypti Jantan dalam Media Radiasi Sinar Gamma 70 Gy terhadap Tingkat Kemunculan Dewasa

Irradiation is one of the main activities in SIT. Currently, its needed a method for producing a male sterile by male pupae irradiation in large quantities and produce sterile adultin high emergence. This study was aimed to analyze the influence of density variations of Aedes aegypti male pupae in gamma ray radiation media of 70 Gy to the rate of adult emergence. This type of research is experimental design with post test only control group. The sample was used in this study as many as 5,400 male pupae. The method was used by irradiated male pupae with different densities of each tube vial (d=2 cm), ie 60, 120, 180, 240 and 300, each of density had 5 repetitions and control (not irradiated). After irradiation, it was observed adult emergence rate. The results showed that an increase in the density of irradiated pupae inversely proportional to the adult emergence rate. Based on the results of ANOVA test with p=0,01, there was influence between the density of irradiated pupae to adult emergence rate. Based on the results of Tukeys test with p=0,01 indicated that adult emergence best rate was in the density of 120 individuals. Based on these findings, irradiation should be done with pupae density was 120 individuals

Entangling macroscopic diamonds at room temperature: Bounds on the continuous-spontaneous-localization parameters

A recent experiment [K. C. Lee et al., Science 334, 1253 (2011)] succeeded in detecting entanglement between two macroscopic specks of diamonds, separated by a macroscopic distance, at room temperature. This impressive results is a further confirmation of the validity of quantum theory in (at least parts of) the mesoscopic and macroscopic domain, and poses a challenge to collapse models, which predict a violation of the quantum superposition principle, which is the bigger the larger the system. We analyze the experiment in the light of such models. We will show that the bounds placed by experimental data are weaker than those coming from matter-wave interferometry and non-interferometric tests of collapse models.Comment: 7 pages, 3 figures, v2: close to the published version, LaTe

The three-body recombination of a condensed Bose gas near a Feshbach resonance

In this paper, we study the three-body recombination rate of a homogeneous dilute Bose gas with a Feshbach resonance at zero temperature. The ground state and excitations of this system are obtained. The three-body recombination in the ground state is due to the break-up of an atom pair in the quantum depletion and the formation of a molecule by an atom from the broken pair and an atom from the condensate. The rate of this process is in good agreement with the experiment on $^{23}$Na in a wide range of magnetic fields.Comment: 10 pages, 2 figures, to be published in Phys. Rev.
