The current study investigates the synthesis and analysis of aspiration noise in synthesized and spoken vowels. Based on the linear source-filter model of speech production, we implement a vowel synthesizer in which the aspiration noise source is temporally modulated by the periodic source waveform. Modulations in the noise source waveform and their synchrony with the periodic source are shown ...

introductiongeopolitics is a word that conjures up images. in one sense, the word provokes ideas of war, empire, and diplomacy: geopolitics is the practice of states controlling and competing for territory. geopolitics had a history before the term itself came in to use in 1899 by swede rudolf kjellen. it is apparent that many of great figures in the history of political thought, from the ancie...

quality of clinical education for medical students has always been a concern in academic medicine. this concern has increased in today’s time-squeeze while faculty members have to fulfill their complementary roles as a teacher, researcher, and practitioner. one of the strategies for program evaluation is obtaining trainees’ feedbacks since they are the main customers of educational programs; ho...

purpose: to report a case of anterior segment eye deposits in a patient on long-term chlorpromazine therapy. case report: a 34 years old man had been on chlorpromazine therapy for 5 years with a total dose of 1,100 gram. since one year ago, he presented with gradual onset of decreased visual acuity in both eyes. slit-lamp examination revealed multiple fine yellow-brown deposits on the corneal e...

Introduction: In many cultures fasting is recommended as a way to protect and promote health. However, there are few studies on the effects of fasting on organ function and resistance to toxic agents such as drugs. This study was conducted to investigate the effect of short-term periodic fasting on the acetaminophen hepatotoxic effects in mice. Methods: In this...

The long-term variability of the multiwavelength blazar emission can be interpreted in terms of orientation variations of a helical, inhomogeneous, non-thermally emitting jet, possibly caused by the orbital motion of the parent black hole in a binary system (Villata & Raiteri 1999). The helical-jet model is here applied to explain the quasi-periodic radio-optical light curves and the broad-band...

The Affective Norms for Polish Short Texts (ANPST) dataset (Imbir, 2016d) is a list of 718 affective sentence stimuli with known affective properties with respect to subjectively perceived valence, arousal, dominance, origin, subjective significance, and source. This article examines the reliability of the ANPST and the impact of population type and sex on affective ratings. The ANPST dataset w...

Gaussian processes are a state-of-the-art method for learning models from data. Data with an underlying periodic structure appears in many areas, e.g., in climatology or robotics. It is often important to predict the long-term evolution of such a time series, and to take the inherent periodicity explicitly into account. In a Gaussian process, periodicity can be accounted for by an appropriate k...
