BIG DATA ALGORITHMS AND PREDICTION: BINGOS AND RISKY ZONES IN SHARIA STOCK MARKET INDEX
Each country with a stock exchange normally calculates various indexes. So is the case
for Malaysia’s Kuala Lumpur Stock exchange (KLSE). FTSE BURSA Malaysia EMAS
Sharia price index (FTBMEMA) is one of its Sharia indexes. In an effort to find which
other indices may forecast this Sharia index, we selected 23 relevant indexes and two
exchange rates. Momentum indicators for short, medium and long term have been
calculated for the variables. The objective of this study is to find predictive indicators
for FTBMEMA out of the population of 188 original and derived variables. Difficulty
arises in reducing the number of variables for regression or other predictive models
like neural networks. In this preliminary study, data mining attribute selection
algorithms along with cross validation criteria have been used, through the use of Java
class library Weka (JCLW), for reducing the number to statistically relevant variables
for our regression estimation in an effort to forecast various performance parameters
for FTBMEMA like performing either in a mean performance range, having jackpots
and bingos or falling into danger zones. Provided the extent of the required predictive
accuracy, the results may bring additional insights for diversifying and hedging
various types of investment portfolios as well as for maximizing returns by portfolio
managers
EXAMINING THE INFLUENCE OF AFFORDABILITY AND ACCESSIBILITY ON TOURIST DELIGHT
The objectives of the study are to assess the relationship and significant influence of affordability and accessibility on tourist delight taking into account the mountain areas of Khyber Pakhtunkhwa province, Pakistan and tourists who visit these sites. This is a survey type quantitative research. Data has been collected through the questionnaires from the selected population. Stratified and convenience sampling techniques are being employed. Sample comprises of respondents from three main regions/strata consisted of Malakand division, Mansehra division and Galiyat region of Khyber Pakhtunkhwa and from each stratum data were data collected using the convenience sampling technique. The Structural Equation Modeling (SEM) was used to test relationship between variables of the study on Smart PLS 4. Results of the study show that the affordability and accessibility have significant relationship with the tourists' delight. The findings suggest that the tourist delight can be increased in the mountain tourism through the travel attributes (affordability and accessibility) have significant impact on the tourist delight
Exploration of nutraceutical potential of herbal oil formulated from parasitic plant
Background: Cuscuta reflexa (C. reflexa) is a parasitic climber of medicinal importance. The present study was aimed to evaluate the nutraceutical potential of C. reflexa stems collected from different hosts and to evaluate the role of the herbal formulation in dandruff, hair fall control as well as hair growth promoter.Materials and Methods: Hair formulations of C. reflexa collected from different host plants were prepared in the form of herbal oils (10% w/v). C. reflexa stems were extracted using mustard oil as base oil by using direct boiling technique. Prepared oil was studied as hair tonic. The experimental protocols used were anti-dandruff hair growth activity, as well as hair fall reduction. Herbal hair oils versus mustard oil were evaluated by applying oils on human volunteers with hair fall and dandruff problem whereas promotion of hair growth activity was conducted on rats. The formulated oils were also characterised for proximate analysis, physiochemical composition, as well as antimicrobial activity.Result: The test oils of C. reflexa collected from Azadiracta indica and Zizyphus jujuba were effective in the promotion of hair growth, dandruff control, as well as reduction in hair fall activity.Conclusion: All the formulated oils showed potent antimicrobial activity against all selected strains of bacteria and fungi.Keywords: Cuscuta reflexa, host plants, Hair fall, Dandruff, Combing assay, Herbal hair oil, Hair growth activity
Approach to Data Science with Multiscale Information Theory
Data Science is a multidisciplinary field that plays a crucial role in
extracting valuable insights and knowledge from large and intricate datasets.
Within the realm of Data Science, two fundamental components are Information
Theory (IT) and Statistical Mechanics (SM), which provide a theoretical
framework for understanding dataset properties. IT enables efficient storage
and transmission of information, while SM focuses on the behavior of systems
comprising numerous interacting components. In the context of data science, SM
allows us to model complex interactions among variables within a dataset. By
leveraging these tools, data scientists can gain a profound understanding of
data properties, leading to the development of advanced models and algorithms
for analysis and interpretation. Consequently, data science has the potential
to drive accurate predictions and enhance decision-making across various
domains, including finance, marketing, healthcare, and scientific research.
In this paper, we apply this data science framework to a large and intricate
quantum mechanical system composed of particles. Our research demonstrates that
the dynamic and probabilistic nature of such systems can be effectively
addressed using a Multiscale Entropic Dynamics (MED) approach, derived from the
Boltzmann methods of SM. Through the MED approach, we can describe the system's
dynamics by formulating a general form of the Nonlinear Schr\"odinger equation
and how it can be applied to various systems with particles and
quasi-particles, such as electrons, plasmons, polarons, and solitons. By
employing this innovative approach, we pave the way for a deeper understanding
of quantum mechanical systems and their behaviors within complex materials.Comment: 12 page
Phenotypes of Alpha 1 Antitrypsin in Karachi, Pakistan
Objective: To determine serum level of the protease inhibitor, to identify phenotypes and determine their frequencies.
Study Design: A prospective study.
Setting: PMRC Research Centre, JPMC and the Aga Khan University Hospital Karachi.
Subjects: Healthy aduIts without history ol peptic ulcer disease and a normal endoscopy.
Methodology: Quantitive measurement of serum alpha 1 AT was carried out by radial immunodiffusion. phenotyping by iso-electric focusing and confirmation of phenotypes by immunofixation and DNA analysis technique.
Results:Serum alpha I AT was low in 13.4% of the subjects. Ni MM phenotype predominated followed by SZ SS, MZ and ZZ. DNA diagnosis accurately resolved the phenotypes as S and Z.
Conclusion: Frequency by phenotype associated with total and intermediate deficiency is less in the populatio
Genetic Variants of Serum Alpha 1 Antitrypsin
Complete absence of data on alpha 1 antitrypsin in this country prompted us to determine serum levels using radial immunodiffusion (RID) and phenotypes by isoelectric focusing (IEF) in 100 healthy adults (52 males and 48 females). Mean serum alpha 1 antitrypsin concentration in healthy subjects was 2.47±0.08 g/l and the main phenotypes MM (70%), M1 M2 (28%) and FM 3(2%) are infrequent in our population (JPMA 45:245,1995)
