A 16-year-old female with a history of neck hemangioma surgery presented with irritable coughs. A computed tomography scan showed anterosuperior and middle mediastinal masses (Figure 1). The patient underwent surgery and the upper and middle mediastinal lesions were removed (Figure 2A). Pathological examination confirmed that the upper and mid...

Background: Individuals with bipolar disorders (BD) are 5x more likely to be arrested, jailed, or convicted of a criminal offense than those in the general population. BD, turn, increases risk for adverse outcomes prisoners post-release, including mood instability, suicide attempts, substance use relapse, and repeat incarceration. Despite these negative sequelae, up 70% BD do not receive mental...

Modern-day problems in statistics often face the challenge of exploring and analyzing complex non-Euclidean object data that do not conform to vector space structures or operations. Examples such objects include covariance matrices, graph Laplacians networks, univariate probability distribution functions. In current contribution a new concurrent regression model is proposed characterize time-va...

Suppose you and I are both editing a document. You make and change and I make a change, concurrently. Now if we want to still be seeing the same document then I need to apply your change after mine and you mine after yours. But we can’t just apply them willy-nilly. I must amend yours somehow and you mine. If my change is written ∆, yours δ, my amended change δ.∆ and yours ∆.δ, we get ∗∆ ∗ ∆.δ =...

In this paper we present a semantic model that is used to interpret a logic that represents concurrent actions having temporal extent. In an earlier paper [Pelavin and Allen, 19861 we described how this logic is used to formulate planning problems that involve concurrent actions and external events. In this paper we focus on the semantic structure. This structure provides a basis for describing...
