Abstract:

Inflation is one of the most important macroeconomic variables. It is vital that policy makers receive accurate forecasts of inflation so that they can adjust their monetary policy to attain stability in the economy which has been shown to lead to economic growth. The purpose of this study is to model inflation and evaluate if applying the Kalman filter to SARIMA models lead to higher forecast accuracy compared to just using the SARIMA model. The Box-Jenkins approach to SARIMA modelling is used to obtain well-fitted SARIMA models and then to use a subset of observations to estimate a SARIMA mo

Abstract:

In recent years, many research works such as Tiao and Tsay (1994), Stock and Watson (1999), Chen et al. (2001), Clements and Jeremy (2001), Marcellino (2002), Laurini and Vieira (2005) and others have described the dynamic features of many macroeconomic variables as nonlinear. Using the approach of Keenan (1985) and Tsay (1989) this study shown that Ghana inflation rates from January 1980 to December 2009 follow a threshold nonlinear process. In order to take into account the nonlinearity in the inflation rates we then apply a two regime nonlinear SETAR model to the inflation rates and then s

Abstract:

Ghana faces a macroeconomic problem of inflation for a long period of time. The problem in somehow slows the economic growth in this country. As we all know, inflation is one of the major economic challenges facing most countries in the world especially those in African including Ghana. Therefore, forecasting inflation rates in Ghana becomes very important for its government to design economic strategies or effective monetary policies to combat any unexpected high inflation in this country.

Abstract:

In this paper two different models for forecasting the number of monthly departing passengers from Sweden to any international destination are developed and compared. The Swedish transport agency produces forecasts on a yearly basis, where net export is the only explanatory variable controlled for in the latest report. More profound studies have shown a relevance of controlling for variables such as unemployment rate, oil price and exchange rates. Due to the high seasonality within passenger flows, these forecasts are based on monthly or quarterly data. This paper shows that a seasonal autoreg

Wind is a fluctuating source of energy and, therefore, it can cause several technical impacts. These can be tackled by forecasting wind speed and thus wind power. The introduction of several statistical models in this field of research has brought to light promising results for improving wind speed predictions.

Over the last three decades, significant research has been carried out in the field of short-term forecasting using statistical models though less work focuses on longer timescales.

Abstract:

Sarcomas are one of the most common types of cancer in children and comprise more than 50 heterogeneous histotypes. The standard therapeutic regimen, which includes surgery, chemotherapy and radiotherapy, does not often prove to be decisive. To improve patient outcome, alternative therapeutic strategies are being evaluated. Among these, RIP-containing immunotoxins (ITs) represent an innovative approach because of their high tumor specificity and cytotoxicity. Recently, in order to evaluate the efficacy of new drugs and develop personalized therapeutic protocols, three-dimensional models (i.e.

Epithelioid sarcoma is a soft tissue tumor with an unusual predilection for the distal extremities in young adults. Despite wide-margin resections the 10-year survival is in the range of 50%. The biology of epithelioid sarcoma remains incompletely understood, but one key feature is the loss of SMARCB1. We use whole genome sequencing of five cases of epithelioid sarcoma matched to normal germline DNA, looking for mutations other than SMARCB1. These index cases are supplemented with three additional tumors and three cell lines that undergo whole transcriptome sequencing and are analyzed for soma

Abstract:

The wide variety of magazines in the South African market and the economic relapse that has been experienc,e d worldwide has given rise to the increasing competition for higher circulation figures and advertising income. This phenomenon especially occurs between publications competing for the same target audience, such as the women's magazines SARIE and rooi rose, competitors over many years in the Afrikaans magazine market. Magazine covers play a critical role in this rivalry due to the direct connection between the popularity of the cover and circulation figures. The more popular the cover o

Abstract:

As a proactive, information-based policing approach, problem-oriented policing emphasizes the use of crime analysis techniques in the analysis of the underlying causes of the problems that police deal with. In particular, analysis applications can be powerful tools for criminal investigation, such as crime reconstruction, profiling, IAFIS, VICAP, and CODIS. The SARA Model represents a problem-solving strategy of problemoriented policing. It aims to address the underlying causes of the problems and create substantial solutions. However, implementing problem-oriented policing requires a signific

Abstract:

Chez les ruminants, l’Acidose Ruminale SubAiguë (ARSA) est une maladie d’origine nutritionnelle qui fait suite à une perturbation des fermentations microbiennes et à une acidité anormale du compartiment ruminal. L’installation chronique de ce dysfonctionnement digestif peut avoir une incidence néfaste sur l’efficacité de production et la santé des animaux. À l’échelle de l’individu ou du troupeau, elle aura pour conséquences des retombées économiques négatives pour l’éleveur. Un des problèmes majeurs de cette maladie est qu’elle ne se manifeste pas par des signes cliniques spécifiques. A l’heu

Abstract:

Le lymphome à cellules du manteau (LCM) est une hémopathie maligne B mature, appartenant à la famille des lymphomes non hodgkiniens. Le LCM est caractérisé par la translocation t(11;14)(q13;q32) qui provoque une expression aberrante de cycline D1. C’est une pathologie rare mais à haut risque de rechute, et qui reste le plus souvent incurable suite à l’apparition de clones chimiorésistants. L’acquisition de résistance est intimement liée aux interactions entre les cellules tumorales et leur microenvironnement. Afin de mimer de la manière la plus pertinente possible ces interactions, nous avons

Abstract:

A serious threat to public health is posed by air pollution, a problem that is spreading around the world. Delhi is one of the most polluted cities in the world, with PM levels frequently exceeding safe limits. This study aims to analyze the levels of PM in Delhi from January 2018 to April 2023, with a focus on PM10 and PM2.5 concentrations. The study uses visualizations of PM concentrations to provide a clear picture of the severity of air pollution in Delhi. In addition, the study examines meteorological parameters, such as temperature, wind speed and humidity, using trend and sea

Abstract:

This study uses aspects of time series methodology to model and forecast major taxes such as Personal Income Tax (PIT), Corporate Income Tax (CIT), Value Added Tax (VAT) and Total Tax Revenue(TTAXR) in the South African Revenue Service (SARS). The monthly data used for modeling tax revenues of the major taxes was drawn from January 1995 to March 2010 (in sample data) for PIT, VAT and TTAXR. Due to higher volatility and emerging negative values, the CIT monthly data was converted to quarterly data from the rst quarter of 1995 to the rst quarter of 2010.

Abstract:

Exosomes (EXOs) are nanovesicles of diameter ranging between 50 to 140 nm, distinguished from other cell-derived vesicles by their origin, size, morphology and composition. Their stimulatory or inhibitory signaling activities are mediated by their content (mRNAs, microRNAs and proteins) that can be transferred from the cells of origin to recipient cells, influencing the surrounding microenvironment besides cell behavior. In this study we investigated EXO-mediated communications in two cancer models, melanoma and Ewing’s sarcoma. In view of our previous results demonstrating miR-221&222 as ke

3D ex vivo tumor models are required which better replicate the microenvironment encountered by tumor cells in vivo. In this study, we applied bone tissue engineering culture techniques to develop an ex vivo 3D bone tumor model. Ewing sarcoma cells were cultured on poly(ε-caprolactone) (PCL) microfiber scaffolds, and cellular growth kinetics, morphology, and infiltration were assessed. Cell/scaffold constructs were then exposed to anticancer drugs for up to 16 days and drug response was compared to 2D controls. Ewing sarcoma cells were capable of attachment and proliferation on PCL scaffolds a
