In this paper we explore Computer-Aided Humor (CAH), where a computer and a human collaborate to be humorous. CAH systems support people’s natural desire to be funny by helping them express their own idiosyncratic sense of humor. Artificial intelligence research has tried for years to create systems that are funny, but found the problem to be extremely hard. We show that by combining the streng...
This study uses the Autoregressive Distributed Lag (ARDL) model to study the dynamic determinant factors that influence both long and short-term international tourism demand in Cambodia from 12 countries. The annual time series data (1994–2013) are used in this study. The study finds that only the international tourism demand model of Australia, Canada, Thailand, the United Kingdom, and USA are...
A new elementary mechanism of radiation due to the oscillatory character of a radiation reaction force appearing when a relativistic charged particle moves along a periodic structure without external fields is investigated. It is shown that the nonsynchronous spatial harmonics of Cherenkov-type radiation (CR) can give rise to the oscillation of a particle which consequently generates undulator-...
We calculate the chiral and thermal susceptibilities for two confining DysonSchwinger equation models of QCD with two light flavours, a quantitative analysis of which yields the critical exponents, β and δ, that characterise the second-order chiral symmetry restoration transition. The method itself is of interest, minimising the influence of numerical noise in the calculation of the order param...
In Drosophila polytene chromosomes, most late-replicating regions remain underreplicated. A loss-of-function mutant of the suppressor of underreplication [Su(UR)] gene suppresses underreplication (UR), whereas extra copies of this gene enhance the level and number of regions showing UR. By combining DNA microarray analysis with manipulation of the number of Su(UR) gene copies, we achieved genom...
SETTING Rio de Janeiro, Brazil, is a middle-income setting with an estimated 1% adult human immunodeficiency virus (HIV) seroprevalence. OBJECTIVE To examine the cost-effectiveness of DOTS in Rio de Janeiro. DESIGN Cost-effectiveness analysis based on cost data and an epidemiological model based on programmatic outcomes from the Health Department in Rio de Janeiro, cost data from the retail...
در این مقاله روشی کارآمد، جهت ارزیابی استتار در تصاویر ماهواره ای ارائه شده است. روش پیشنهادی از دو بخش اصلی مبتنی بر روش تناظریابی الگو و الگوریتم استخراج عارضه ی ur-sift (uniform robust scale invariant feature transform) تشکیل شده است. در بخش اول میزان تمایز عارضه ی هدف و پس زمینه با استفاده از روش تناظریابی الگو برآورد شده و با بهره گیری از یک تابع گوسی به صورت وزن دار، یک معیار کمی جهت توصی...
Haplotypes are an important resource for a large number of applications in human genetics, but computationally inferred haplotypes are subject to switch errors that decrease their utility. The accuracy of computationally inferred haplotypes increases with sample size, and although ever larger genotypic data sets are being generated, the fact that existing methods require substantial computation...
We consider a Black-Scholes type model, but with volatility being a Markov Chain process. Assuming that the stock price is observed at discrete, possibly random times, the goal is to estimate the current volatility value. The model parameters, that is, the possible volatility values and transition probabilities, are estimated using the Multiscale Trend Analysis method of Zaliapin, Gabrielov and...
we show that when both sources ( lepton flavor violation sources and cp-violating phases) are present, the electric dipole moment of the electron, $d_e$, receives a contribution from the phase of the trilinear $a$-term of staus, $phi_{a_ au}$. for $phi_{a_ au}=pi/2$, the value of $d_e$, depending on the ratios of the lfv mass elements, can range between zero and three orders of magnitude a...
