The Supply and Demand for Exports of Pakistan: The Polynomial Distributed Lag Model (PDL) Approach

In the global economy, the performance of any country will greatly depend on the performance of its exports. The trade performance determines the prospects of change. It helps countries win friends, and break the traditional mould of isolation and indifference. The performance of exports of countries depends on various price and non-price factors. In international trade transactions it is important to recognise that these transactions require some amount of time that occurs between the decision to buy and actual delivery of the product from foreign country. In the Econometric modelling lag occupies a central role. It is recognised that due to psychological, technical and institutional reasons, a dependent variable may respond to explanatory variables with lapse of time, in particular when dealing with time-series trade models. A number of studies have been conducted to examine the export performance of Pakistan. In the best of our knowledge, no study has been undertaken incorporating lags to examine the individual and cumulative impact of determinants of export performance of Pakistan. Thus, the ultimate purpose of this paper is to estimate consistent individual (short run) and cumulative (long run) elasticities of both export demand and supply determinants using annual data over the period 1972–2000 by applying Almon approach.

The Impact of FDI on Economic Growth under Foreign Trade Regimes: A Case Study of Pakistan

FDI has been one of the defining features of the world economy over the past two decades. It has grown at an unprecedented pace for more than a decade. Liberalisation of the foreign trade regime is an integral part of growth of FDI. This paper investigates the trade policy regime followed by Pakistan that has influenced significantly both the amount of inward FDI received and economic growth. Our findings maintain that the Bhagwati Hypothesis Emphasis on both export promotion policy and inward FDI on the part of the government can get the desired result of economic growth.Foreign Investment, Economic Growth, Trade, Pakistan

Evaluating the Effects of Textural Properties on the Strength Parameters of Marbles from North-Western Khyber Pakhtunkhwa, Pakistan

Marble is globally used as a natural stone for decorative and architectural purposes. Primary utilization of marble is as building and dimension stones. Mechanical properties and aesthetic aspects are major characteristics of marble and decisive factors for its selection and utilization. It is therefore imperative to evaluate the key strength properties i.e. Uniaxial Compressive Strength (UCS) and Uniaxial Tensile Strength (UTS) of marble before its utilization. These key strength parameters are dependent on textural features of marble. Present study investigates the effect of two key textural features i.e. grain size and grain shape on two key strength parameters i.e. UCS and UTS of marble samples taken from three different regions i.e. Buner, Chitral and Swat in the north western part of Khyber Pakhtunkhwa. Correlation and regression analysis between these textural properties and strength parameters revealed that prominent textural features of grain size and shape can be used as a quick indicator for assessment of strength parameters and as guideline for appropriate utilization of marble

International Trade of Pharmaceutical and Health Industries Along the “Belt and Road” Countries

In recent years, the medical and health industry has become a new engine for global economic development. As a cluster of industries, the level of world's medical and health industry varies. Standards, as a comprehensive reflection and strategic resource of the competitiveness of enterprises, industries, regions, and even countries, have become an important experience and basic consensus for economic development at home and abroad. This article conducts research on the current status of standardization in the pharmaceutical and health industry both domestically and internationally. This study mainly analyzes the bilateral trade volume and industrial structure of pharmaceutical products between China and countries along the “Belt and Road” (BR), and empirically analyzes the influencing factors of pharmaceutical products trade between China and countries along the "Belt and Road" according to the trade situation. Using the explicit comparison index, the trade complementarity index, and the trade intensity index, select fifteen countries that are representative of the trade of pharmaceutical products in China and the regions along "the Belt and Road." Then, divide pharmaceutical products into traditional Chinese medicine and western medicine. Finally, analyze the problems and challenges that are associated with pharmaceutical products in China and sample countries. Through comparative analysis of organizational structure, standard system, and standard formulation and revision, combined with the practical experience of standardization in BR countries' pharmaceutical and health industry trade, measures and suggestions are proposed on how to accelerate the role of adjustment in pharmaceutical and health industry trade

AI and Digital Twin Transforms in the Construction of Precision Medical Model: Healthcare Management in Smart Cities

In recent years, the integration of artificial intelligence (AI) and digital twin (DT) is driving a new revolution in the healthcare field. Precision medical methods can utilize the complex computing techniques and models of AI, combined with various genetic and non-genetic data, to enable the system to reason and learn under the drive of data and algorithms, assisting clinical doctors and researchers in making more accurate related decisions. Research has shown that AI and DT has shown enormous technological application space in genomics, clinical cancer treatment, molecular imaging, and other fields, but it also faces potential challenges such as system bias, correlation limitations, algorithm black boxes, and unfairness. This requires the use of AI and DT transformations to build a precision medical intelligent system, which can update, capture, and study real-world data in real-time and simulate in DT. This study proposes that real-world data should be constructed from information system data and medical knowledge data from various hospitals, combined with the roles of real-world evidence (RWE), randomized clinical trial (RCT), genetic research, and AI technology in precision medicine, to innovatively design a precision medical smart system in the social 5.0 smart city. This work also proposes the structure and operating standards of the smart system, providing innovative ideas and contributions for the future construction of precision medical smart systems in society

DNA and Plaintext Dependent Chaotic Visual Selective Image Encryption

Visual selective image encryption can both improve the efficiency of the image encryption algorithm and reduce the frequency and severity of attacks against data. In this article, a new form of encryption is proposed based on keys derived from Deoxyribonucleic Acid (DNA) and plaintext image. The proposed scheme results in chaotic visual selective encryption of image data. In order to make and ensure that this new scheme is robust and secure against various kinds of attacks, the initial conditions of the chaotic maps utilized are generated from a random DNA sequence as well as plaintext image via an SHA-512 hash function. To increase the key space, three different single dimension chaotic maps are used. In the proposed scheme, these maps introduce diffusion in a plain image by selecting a block that have greater correlation and then it is bitwise XORed with the random matrix. The other two chaotic maps break the correlation among adjacent pixels via confusion (row and column shuffling). Once the ciphertext image has been divided into the respective units of Most Significant Bits (MSBs) and Least Significant Bit (LSBs), the host image is passed through lifting wavelet transformation, which replaces the low-frequency blocks of the host image (i.e., HL and HH) with the aforementioned MSBs and LSBs of ciphertext. This produces a final visual selective encrypted image and all security measures proves the robustness of the proposed scheme

Indoor and outdoor residual spraying of a novel formulation of deltamethrin K-Othrine® (Polyzone) for the control of simian malaria in Sabah, Malaysia

Since 2000, human malaria cases in Malaysia were rapidly reduced with the use of insecticides in Indoor Residual Spray (IRS) and Long-Lasting Insecticide Net (LLIN). Unfortunately, monkey malaria in humans has shown an increase especially in Sabah and Sarawak. The insecticide currently used in IRS is deltamethrin K-Othrine® WG 250 wettable granule, targeting mosquitoes that rest and feed indoor. In Sabah, the primary vector for knowlesi malaria is An. balabacensis a species known to bite outdoor. This study evaluates an alternative method, the Outdoor Residual Spray (ORS) using a novel formulation of deltamethrin K-Othrine® (PolyZone) to examine it suitability to control knowlesi malaria vector in Sabah, compared to the current method. The study was performed at seven villages in Sabah having similar type of houses (wood, bamboo and concrete). Houses were sprayed with deltamethrin K-Othrine® (PolyZone) at two different dosages, 25 mg/m2 and 30 mg/m2 and deltamethrin K-Othrine® WG 250 wettable granule at 25 mg/m2, sprayed indoor and outdoor. Residual activity on different walls was assessed using standard cone bioassay techniques. For larval surveillances, potential breeding sites were surveyed. Larvae were collected and identified, pre and post spraying. Adult survey was done using Human Landing Catch (HLC) performed outdoor and indoor. Detection of malaria parasite in adults was conducted via microscopy and molecular methods. Deltamethrin K-Othrine® (PolyZone) showed higher efficacy when sprayed outdoor. The efficacy was found varied when sprayed on different types of wall surfaces. Deltamethrin K-Othrine® (PolyZone) at 25 mg/m2 was the most effective with regards to ability to high mortality and effective knock down (KD). The vector population was reduced significantly post-spraying and reduction in breeding sites as well. The number of simian malaria infected vector, human and simian malaria transmission were also greatly reduced
