In this paper, we introduce a novel problem of audio-visual event localization in unconstrained videos. We define an audio-visual event as an event that is both visible and audible in a video segment. We collect an Audio-Visual Event (AVE) dataset to systemically investigate three temporal localization tasks: supervised and weakly-supervised audio-visual event localization, and cross-modality l...

Two categories of objects in the environment-animals and man-made manipulable objects (tools)-are easily recognized by either their auditory or visual features. Although these features differ across modalities, the brain integrates them into a coherent percept. In three separate fMRI experiments, posterior superior temporal sulcus and middle temporal gyrus (pSTS/MTG) fulfilled objective criteri...

In the last years, the adoption of active systems has increased in many fields of computer science, such as databases, sensor networks, and software engineering. These systems are able to automatically react to events, by collecting information from outside and internally generating new events. However, the collection of data is often hampered by uncertainty and vagueness that can arise from th...

sleep apnea, and particularly obstructive sleep apnea, is a common disorder that is characterized by a repetitive, partial or complete cessation of air flow, associated with oxyhemoglobin desaturation and an increased effort to breath. in recent years, orthodontists have been interested and involved in the management of this disorder since it has been shown that oral appliance therapy can be an...

background: esophageal cancer is one of the prevalent cancers in east azerbaijan province. the aims of this study are to estimate the survival rate of patients with esophageal cancer by treatment modalities and tumor location, as well as risk factors such as cigarette smoking, family history, age at diagnosis, and gender. materials and methods: in a cross-sectional study we evaluated 142 patien...

The differential temporal dynamic logic dTL is a logic to specify temporal properties of hybrid systems. It combines differential dynamic logic with temporal logic to reason about the intermediate states reached by a hybrid system. The logic dTL supports some linear time temporal properties of LTL. It extends differential temporal dynamic logic dTL with nested temporalities. We provide a semant...

Two tests of auditory recognition memory were given to four patients with bilateral hippocampal damage (H+) and three patients with large medial temporal lobe lesions and additional variable damage to lateral temporal cortex (MTL+). When single stimuli were presented, performance was normal across delays as long as 30 sec, presumably because information could be maintained in working memory thr...

Different temporal logics tend to emphasise different aspects of a hybrid system. In this paper, we study the predicative interpretation of Duration Calculus (DC) and Temporal Logic of Actions (TLA) and the link between them. A notation called generic composition is used to simplify the manipulation of predicates. The modalities of possibility and necessity become generic composition and its in...

1. Modal logic Modal notions are pervasive in the meaning of a wide range of expressions from grammatical categories, such as tenses, to the lexical semantics of particular words, such as modal adverbials (probably, necessarily) and modal auxiliaries (must, may, can). The best known modalities are the alethic 1 modalities necessary and possible. Other modalities include temporal, de-ontic, epis...
