Finiteness and the falsification by fellow traveler property  [PDF]
Murray J Elder
Mathematics , 2006, DOI: 10.1023/A:1021273013372
Abstract: We prove that groups enjoying the falsification by fellow traveler property are of type $F_3$, and have at most an exponential second order isoperimetric function.
Regular geodesic languages and the falsification by fellow traveler property  [PDF]
Murray Elder
Mathematics , 2004, DOI: 10.2140/agt.2005.5.129
Abstract: We furnish an example of a finite generating set for a group that does not enjoy the falsification by fellow traveler property, while the full language of geodesics is regular.

Abstract: Introduction. Unwanted pregnancy is one the most important subjects in family planning programme. Physical and psycological problems for mothers, children and family are the consequences of this matter. In this study we are trying to evaluate the rate of unwanted pregnancies and their consequences in Najafabad villages. Methods. In a descriptive study, all 788 pregnant women aged between 15 to 45 years old were considered. The data was collected by using a questionnaire and their record files. Descriptive and analytic statistics were used. Findings. Near fourty percent of the pregnancies were unwanted at least for one of the couple. Although 96.3 percent of women had knowledge about the advantages and disadvantages of contraceptive methods, only 29 percent of them had knowledge about injective of plaintive methods. Fifty one percent of women who had unwanted pregnancy liked to terminate it and 31.7 percent of them had attempt to do it at least one time. conclusion. Knowledge level is really high in these women, however, they have 42 percent unwanted pregnancies. It is necessary to promote attitudes and practices of family planning in the field study by interventional methods.
Leaky cavities with unwanted noise  [PDF]
A. A. Semenov,D. Yu. Vasylyev,W. Vogel,M. Khanbekyan,D. -G. Welsch
Physics , 2006, DOI: 10.1103/PhysRevA.74.033803
Abstract: A phenomenological approach is developed that allows one to completely describe the effects of unwanted noise, such as the noise associated with absorption and scattering, in high-Q cavities. This noise is modeled by a block of beam splitters and an additional input-output port. The replacement schemes enable us to formulate appropriate quantum Langevin equations and input-output relations. It is demonstrated that unwanted noise renders it possible to combine a cavity input mode and the intracavity mode in a nonmonochromatic output mode. Possible applications to unbalanced and cascaded homodyning of the intracavity mode are discussed and the advantages of the latter method are shown.

Abstract: A prospective study was done at LMC Jamshoro over period of one year to evaluate the incidence of complicationsrelated to termination of unwanted pregnancies. Total of 450 patients were admitted with abortion, of these12(2.66%) gave history of induced abortion. 9(75%) women were multiparae and 3(25%) were nulliparus.Three women (25%) died, one (8.33%) needed permanent colostomy and 2(16.66%) developed wound dehiscence.
Complexity of Canadian Traveler Problem Variants  [PDF]

Computer Science , 2012,
Abstract: The Canadian traveler problem (CTP) is the problem of traversing a given graph, where some of the edges may be blocked - a state which is revealed only upon reaching an incident vertex. Originally stated by Papadimitriou and Yannakakis (1991), the adversarial version of CTP was shown to be PSPACE-complete, with the stochastic version shown to be #P-hard. We show that stochastic CTP is also PSPACE-complete: initially proving PSPACE-hardness for the dependent version of stochastic CTP,and proceeding with gadgets that allow us to extend the proof to the independent case. Since for disjoint-path graphs, CTP can be solved in polynomial time, we examine the complexity of the more general remote-sensing CTP, and show that it is NP-hard even for disjoint-path graphs.

Abstract: Background: Despite expanded coverage of family planning in Iran, unwanted pregnancy is a common problem. The aim of this study was to explore women’s experiences of unwanted pregnancy in Shahroud public health centers.Methods: Purposive Sampling was conducted by means of focus group discussions (FGDs) and in-depth interviews and by a semi-constructed questionnaire in this qualitative research. Five (FGDs) with 23 women in third trimester in pregnancy and 4 in-depth interviews with women with history of induced abortion were done. The method of Content analysis was used to analyze the data. Results: Results of the study can be divided into 4 categories: causes of naming pregnancy as an unwanted pregnancy, causes of unwanted pregnancy; husband, family and relatives’ reaction to unwanted pregnancy and the process of acceptance of unwanted pregnancy. Not planning for pregnancy due to physical, emotional and financial non-readiness for pregnancy and believe in two child policy were the main causes of naming pregnancy as unwanted by women. Process of adapting to pregnancy included not accepting pregnancy, trying abortion, accepting fetus and finally negative emotions towards past thoughts about abortion. Fathers and mothers had important roles in acceptance and continuation of pregnancy.Conclusion: Women with unwanted pregnancy face emotional and psychological problems. Health care providers need to support couples to combat this critical period.
Quantum Knowledge, Quantum Belief, Quantum Reality: Notes of a QBist Fellow Traveler  [PDF]
Howard N. Barnum
Physics , 2010,
Abstract: I consider the "Quantum Bayesian" view of quantum theory as expounded in a 2006 paper of Caves, Fuchs, and Schack. I argue that one can accept a generally personalist, decision-theoretic view of probability, including probability as manifested in quantum physics, while nevertheless accepting that in some situations, including some in quantum physics, probabilities may in a useful sense be thought of as objectively correct. This includes situations in which the ascription of a quantum state should be thought of as objectively correct. I argue that this does not cause any prima facie objectionable sort of action at a distance, though it may involve adopting the attitude that certain dispositional properties of things are not "localized" at those things. Whether this insouciant view of nonlocality and objectivity can survive more detailed analysis is a matter for further investigation.
Inferring Asymmetry of Inhabitant Flow using Call Detail Records  [cached]

Journal of Advances in Information Technology , 2011, DOI: 10.4304/jait.2.4.239-249
Abstract: In this research, we carry out a study of the inhabitant flow using a large mobile phone data with location estimates from subscribers in Suffolk county, Massachusetts, USA that reveals the asymmetry in the flows, which reflects the way that people travel daily. People occasionally travel in a non-symmetrical way. For instance, they would take one route traveling from home to a destination and a different route while returning home. By analyzing the flow over the space, the results show that there exists asymmetrical flows, which account for 33% of all inhabitant flows. In addition, high asymmetrical flows are observed in trips between low and high congested areas e.g. urban and suburban areas, as well as trips made to and from low populated areas e.g. ommercial areas.
A traveler-centered intro to kinematics  [PDF]
P. Fraundorf
Physics , 2012,
Abstract: Treating time as a local variable permits robust approaches to kinematics that forego questions of extended-simultaneity, which because of their abstract nature might not be addressed explicitly until a first relativity course and even then without considering the dependence of clock-rates on position in a gravitational field. For example we here use synchrony-free ``traveler kinematic" relations to construct a brief story for beginning students about: (a) time as a local quantity like position that depends on ``which clock", (b) coordinate-acceleration as an approximation to the acceleration felt by a moving traveler, and (c) the geometric origin (hence mass-independence) of gravitational acceleration. The goal is to explicitly rule out global-time for all from the start, so that it can be returned as a local approximation, while tantalizing students interested in the subject with more widely-applicable equations in range of their math background.
