I test for welfare-induced migration by comparing AFDC participation in border counties to interior counties in the same state. If migration costs are lower for border county residents, border counties on the high-benefit side of a state border should have higher welfare participation relative to the state's interior counties. Border counties on the low-benefit side should have lower welfare pa...

The axiomatic approach to parallel transport theory is partially discussed. Bijective correspondences between the sets of connections, (axiomatically defined) parallel transports and transports along paths satisfying some additional conditions are constructed. In particular, the equivalence between the concepts “connection” and “(axiomatically defined) parallel transport” is established. Bozhid...

Bike Share systems are becoming increasingly popular in urban areas. With growing membership and expansion of service comes many operational challenges. A major challenge in their operations is the unbalanced demand and supply at bike stations as a function of time. Figure 1 shows number of bike trips in Jan 2017, aggregated into time intervals of 30 minutes according to start time, and summed ...

In this paper, we give some sharper refinements and generalizations of inequalities related to Shafer-Fink's inequality for the inverse sine function stated in Theorems 1, 2, and 3 of Bercu (Math. Probl. Eng. 2017: Article ID 9237932, 2017).

A concise discussion of the axiomatic approach to the concept of parallel transport is presented. In particular, attention is drawn to a bijective mapping between the sets of connections and (axiomatically defined) parallel transports. The transports along paths are pointed as a generalization of the (axiomatically defined) parallel transports, which form their proper subset. Some properties of...

A pneumatic walking training aid for amputees is described. It was developed by the late Biomechanical Research and Development Unit, Roehampton, from an original design by Professor Little in Australia. The walking aid has been used successfully on the majority of below-knee and through-knee patients rehabilitated in the Roehampton Walking Training School since 1976. There have been no complic...

We review definitions of generalized parallel transports in terms of Cheeger-Simons differential characters. Integration formulae are given in terms of Deligne-Beilinson cohomology classes. These representations of parallel transport can be extended to situations involving distributions as is appropriate in the context of quantized fields. LAPTH-1099/05 SPhT-T04/080

On 7 December 1988, a severe earthquake hit in Armenia, a former republic of the Soviet Union (USSR); on 11 September 2001, a manmade attack of similar impact hit New York City. These events share similar implications for the role of the uninjured survivor. With basic training, the uninjured survivors could save lives without tools or resuscitation equipment. This article makes the case for tea...

BACKGROUND The emergence of advanced IT and cloud services has beneficially supported the information-intensive tourism industry, simultaneously caused extreme competitions in attracting customers through building efficient service platforms. On response, numerous nations have implemented cloud platforms to provide value-added sightseeing information and personal intelligent service experiences...
