Comparing methods for estimation of heterogeneous treatment effects using observational data from health care databases

T. Wendling, K. Jung, A. Callahan, A. Schuler, more

Statistics in Medicine > 37 > 23 > 3309 - 3324

There is growing interest in using routinely collected data from health care databases to study the safety and effectiveness of therapies in “real‐world” conditions, as it can provide complementary evidence to that of randomized controlled trials. Causal inference from health care databases is challenging because the data are typically noisy, high dimensional, and most importantly, observational....

A Multi-agent Approach to SACReD Transactions for E-commerce Applications

M. Younas, N. H. Shah, K. -M. Chao

Lecture Notes in Computer Science > E-Commerce and Web Technologies > Agents > 119-128

E-commerce systems provide Web users with different facilities such as online banking, online (window) shopping, and online auctions. However, behind the provision of these facilities are certain requirements posed by the e-commerce applications including: data consistency, concurrency, dynamic behaviour, fault tolerance and high availability. Our research identifies that traditional ACID and agent...

Assessment of Eco-Friendly Natural Antimicrobial Textile Finish Extracted from Aloe Vera and Neem Plants

M. F. Khurshid, M. Ayyoob, M. Asad, S. N. H. Shah

Fibres & Textiles in Eastern Europe > 2015 > Nr 6 (114) > 120--123

The aim of the present work was to assess an eco friendly natural antimicrobial textile finish extracted from Aloe gel and Neem plants. Extracted Aloe gel and active substance of Neem were mixed in a mordant to form a finish. Bleached cotton samples were treated with 5, 7, and 10% concentrations of Aloe gel and Neem separately. The same samples were then treated with a hybrid combination of Aloe gel...

Optimal credit period and ordering quantity for credit dependent trended demand and deteriorating items with maximum lifetime

N. H. Shah, D. B. Shah, D. G. Patel

Control and Cybernetics > 2015 > Vol. 44, no. 2 > 311--320

In this paper, an inventory system is analyzed regarding a trended demand. The seller oﬀers its buyer a credit period for settling the account, which attracts more buyers and enhances market demand. However, the oﬀer of credit period leads to default risk for the supplier. The units in inventory are deteriorating continuously and also have deﬁnite maximum lifetime. The aim is to maximize the proﬁt...

Tramadol inhibits the contractility of isolated human myometrium

N. H. Shah, E. Thomas, R. Jose, J. Peedicayil

Autonomic and Autacoid Pharmacology > 33 > 1-2 > 1 - 5

This study was conducted to determine whether the atypical opioid analgesic tramadol inhibits the contractility of isolated non‐pregnant human myometrium. Ten strips of non‐pregnant human myometrium stimulated with 55 mm potassium chloride (KCl) were treated with three concentrations (30, 100 and 300 μm) of tramadol to test for any inhibitory effect of tramadol. The effects of concurrent administration...

Facile processing of Si-Cu core-shell as potential meta-atom materials

M. A. Salim, H. Misran, S. Z. Othman, N. N. H. Shah, more

2012 IEEE 3rd International Conference on Photonics > 159 - 162

2012 IEEE 3rd International Conference on Photonics (ICP 2012)

Monodispersed spheres of Si-Cu core-shell nanocomposite with silica as core and copper as shell were successfully synthesized by a modified two-step synthesis method. Spherical particles of silica core were first synthesized using a modified Stöber method using nonsurfactant template. The obtained monodispersed silica spheres were successfully coated with copper through a modified sol-gel method employing...

Inventory models and trade credit: a review

H. Soni, N. H. Shah, C. K. Jaggi

Control and Cybernetics > 2010 > Vol. 39, no 3 > 867-882

This article reviews the literature on quantitatively oriented approaches for determining the optimal lot-size when supplier offers credit period to the retailer to settle their account. An attempt is made to provide an up-to-date review of existing literature, concentrating on descriptions of the types of problems that have been solved and important structural results.

An EOQ model with time dependent deterioration under discounted cash flow approach when supplier credits are linked to order quantity

B. J. Shah, N. H. Shah, Y. K. Shah

Control and Cybernetics > 2007 > Vol. 36, no 2 > 405-423

This article deals with an inventory model under a situation in which the supplier offers the purchaser some credit period if the purchaser orders a large quantity. Shortages are not allowed. The effects of the inflation rate on purchase price, ordering price and inventory holding price, time dependent deterioration of units and permissible delay in payment are discussed. A mathematical model is developed...

Field evaluation of lentil cultivars inoculated with Rhizobium leguminosarum bv. viciae strains for nitrogen fixation using nitrogen-15 isotope dilution

F. Y. Hafeez, N. H. Shah, K. A. Malik

Biology and Fertility of Soils > 2000 > 31 > 1 > 65-69

AbstractA 15N isotope dilution technique was applied to quantify the extent of N2 fixation in lentil (Lens culinaris Medik.) cultivars as influenced by Rhizobium leguminosarum bv. viciae strains in a field experiment in Pakistan. The experiment was conducted on a soil with a very small indigenous rhizobial population and where N was a limiting factor for crop production. Significant variations in...
