High temperature expansion applied to fermions near Feshbach resonance

We show that, apart from a difference in scale, all of the surprising recently observed properties of a degenerate Fermi gas near a Feshbach resonance persist in the high temperature Boltzmann regime. In this regime, the Feshbach resonance is unshifted. By sweeping across the resonance, a thermal distribution of bound states (molecules) can be reversibly generated. Throughout this process, the interaction energy is negative and continuous. We also show that this behavior must persist at lower temperatures unless there is a phase transition as the temperature is lowered. We rigorously demonstrate universal behavior near the resonance.Comment: 4 pages, 4 figures (3 color, 1 BW), RevTeX4; ver4 -- updated references, changed title -- version accepted for publication in Physical Review Letter

Evaluasi Penerapan Balance Scorecard terhadap Efisiensi Kinerja Karyawan di Divisi Penjualan PT. Auto 2000

In this globalization area, the competition become tight and global so the firms that bound in business competition is demand to work more productive and have a good work to reach the firm purposes’. The firms should be have anticipation and tactic for technology and information development, and if the firms don’t have it, the problem will come from inside and outside from the firms itself. The method is take a measurement system of working experience that hopefully can make the firms condition well and have good effort for the firms to face out the competition. Balance Scorecard system is one of interesting solution to apply in transformation era because the system have four point of view, financial perspective, customer perspective, internal business prosess perpective, and learning and growth perspective. As one of measurement system which have link with strategic, the four point of view must show the link and relationship as one strategic in reach the long term purpose.In this research, the writer did interview and observation. The method of this research is analytic descriptive method. The data that used is selling report on period January until June 2008 and January until June 2009. The analysis of data is using Data Paired Sample T Test ( two pair sample test ) and can be taken a hypothesis which is Balance Scorecard that it make the increase of labor works. This hypothesis can be looked from statistic result, 0.071. This result mean the hypothesis above is acceptable because of the fulfill of criteria of acceptance HO, HO is acceptable if the probability 0.05.Balanced Scorecard hopefully can give balancing and make the relation between financial and non - financial is unity. Besides, the applyment of Balanced Scorecard, will help manager in make strategic decision that have connected with operational activity in the firm efficient and increase the activity in the future

Running anti-de Sitter radius from QCD-like strings

We consider renormalization effects for a bosonic QCD-like string, whose partons have $1/p^{2}$ propagators instead of Gaussian. Classically this model resembles (the bosonic part of) the projective light-cone (zero-radius) limit of a string on an AdS${}_5$ background, where Schwinger parameters give rise to the fifth dimension. Quantum effects generate dynamics for this dimension, producing an AdS${}_5$ background with a running radius. The projective light-cone is the high-energy limit: Holography is enforced dynamically.Comment: 12 page

Potential Fire Hazard, Vulnerability and Family Wellbeing of Jatinegara Public House\u27s Residents

Public houses usually are a high density residential which leads to fire hazard, poor emergency services, as well as the highly increased of family vulnerability. This study aims to analyze the potential fire hazard, vulnerability, and subjective wellbeing of families living in the Jatinegara public house. The design of this study was cross sectional involving 157 families whom selected by stratified random sampling. The study found that age of wife and attitude towards the hazard of fire had a positive relationship to subjective wellbeing of the family. Social dimension and economic dimensions of vulnerability had a negative relationship with subjective wellbeing. Results of regression analysis found that age of wife and familiy\u27s attitudes toward the fire hazard had a positive effect on subjective wellbeing of the family, while the age of husband, income per capita, social vulnerability, and vulnerability of economic had a negative effect on subjective wellbeing of the family

Jumble Java Byte Code to Measure the Effectiveness of Unit Tests

Jumble is a byte code level mutation testing tool for Java which inter-operates with JUnit. It has been designed to operate in an industrial setting with large projects. Heuristics have been included to speed the checking of mutations, for example, noting which test fails for each mutation and running this first in subsequent mutation checks. Significant effort has been put into ensuring that it can test code which uses custom class loading and reflection. This requires careful attention to class path handling and coexistence with foreign class-loaders. Jumble is currently used on a continuous basis within an agile programming environment with approximately 370,000 lines of Java code under source control. This checks out project code every fifteen minutes and runs an incremental set of unit tests and mutation tests for modified classes. Jumble is being made available as open source

Microbial attachment properties in expanded-bed, activated carbon anaerobic filters

A completely mixed, expanded-bed, anaerobic granular activated carbon filter was operated on synthetic wastewaters in which acetate was the only organic carbon source. Steady-state performance was achieved for two influent acetate concentrations: namely, 800 and 1,600 mg/L. Steady-state removal efficiencies in chemical oxygen demand, dissolved organic carbon, and acetate exceeding 96, 97, and 98 percent were obtained, respectively. A steady-state biofilm kinetic model was employed for analyzing the two sets of "steady-state" data. The modeling effort was successful in describing trends and effects; however, insufficient data were available to properly calibrate the model and obtain reliable values for the parametric constants.U.S. Department of the InteriorU.S. Geological SurveyOpe

Dual neutral variables and knot solitons in triplet superconductors

In this paper we derive a dual presentation of free energy functional for spin-triplet superconductors in terms of gauge-invariant variables. The resulting equivalent model in ferromagnetic phase has a form of a version of the Faddeev model. This allows one in particular to conclude that spin-triplet superconductors allow formation of stable finite-length closed vortices (the knotted solitons).Comment: Replaced with version published in PRL (added a discussion of the effect of the coupling of the fields {\vec s} and {\vec C} on knot stability). Latest updates of the paper and miscellaneous links related to knotted solitons are also available at the homepage of the author http://www.teorfys.uu.se/PEOPLE/egor/ . Animations of knotted solitons by Hietarinta and Salo are available at http://users.utu.fi/h/hietarin/knots/c45_p2.mp

Environmental Feedbacks and Engineered Nanoparticles: Mitigation of Silver Nanoparticle Toxicity to Chlamydomonas reinhardtii by Algal-Produced Organic Compounds

The vast majority of nanotoxicity studies measures the effect of exposure to a toxicant on an organism and ignores the potentially important effects of the organism on the toxicant. We investigated the effect of citrate-coated silver nanoparticles (AgNPs) on populations of the freshwater alga Chlamydomonas reinhardtii at different phases of batch culture growth and show that the AgNPs are most toxic to cultures in the early phases of growth. We offer strong evidence that reduced toxicity occurs because extracellular dissolved organic carbon (DOC) compounds produced by the algal cells themselves mitigate the toxicity of AgNPs. We analyzed this feedback with a dynamic model incorporating algal growth, nanoparticle dissolution, bioaccumulation of silver, DOC production and DOC-mediated inactivation of nanoparticles and ionic silver. Our findings demonstrate how the feedback between aquatic organisms and their environment may impact the toxicity and ecological effects of engineered nanoparticles
