Many path planning algorithms leverage A* to determine optimal paths. However, when an actor deviates from the optimal path, a typical application of A* executes a new search from the deviation point to the goal. This approach redundantly calculates paths that may have been examined during the initial search, rather than leveraging previous information. We introduce Plan-B A* (PBA*), which uses...

Background Although recent studies have indicated the potential adverse effects of maternal bisphenol A (BPA) exposure on pregnancy such as increasing the risk of pre-eclampsia, epidemiological evidence is limited. We aimed to evaluate the relationship between maternal BPA exposure and the risk of pre-eclampsia. Methods We conducted a nested case-control study among 173 women (74 cases of pre...

Ray optical modeling of wave propagation is often used for the prediction of the field strength (and delay spread) in wireless mobile communication networks. However, the practical use of these deterministic models is limited due to their high computational demands. For large areas in urban or indoor scenarios the computation times are in the range of hours which is too long for the planning of...

In NTCIR3 QAC1, we proposed a method to introduce an A search control into sentential matching mechanism for Japanese question answering systems, in order to reduce the turn-around time while keeping the accuracy of the answers. Using the method, we do not have to any preprocessing on a document database, and we may use any IR systems with writing a simple wrapper program. There however is a pr...

OBJECTIVE To verify neurokinin B (NKB) and urotensin II (UII) plasma levels in pre-eclampsia (PE) and to determine the relationship between plasma NKB and UII levels. METHOD A total of 60 women in the third trimester of pregnancy were recruited, 40 women with PE (study patients) and 20 age- and BMI-matched normotensive women (healthy controls). They were divided into three groups: the 20 norm...

The pregnant patient with partial lipodystrophy developing acute renal failure—onset of de novo membranoproliferative glomerulonephritis Key words: acute renal failure; pregnancy; partial lipo-towards the end of the gestation period, between 34 dystrophy; low C3; membranoproliferative nephritis and 38 weeks, and it is invariably the result of pre-eclampsia and its complications or the result of...

Thai typed character recognition has been a very most popular research topic in Thailand. There are three commercial Thai OCR softwares available to the public at the present. But none of them can preserve the type styles of the original document image such as bold, italics, normal, and bold & italics styles into the output text file. This paper presents the technique for preserving the specifi...

An open problem about the max-norm of the spline orthoprojector is formulated. It gives rise to several conjectures about the orthoprojectors onto some spaces of polynomials. We discuss in this note several open questions concerning the orthogonal projector onto spline spaces. The main advance on the subject has of course been Shadrin’s proof [9] of de Boor’s conjecture [1] that the max-norm of...

We propose a method for preprocessing an eightneighbor gridworld to generate a subgoal graph and a method for using this subgoal graph to find shortest paths faster than A*, by first finding high-level paths through subgoals and then shortest low-level paths between consecutive subgoals on the high-level path.
