Fiscal Deficits and Debt Dimensions of Pakistan
Pakistan continues to suffer from a syndrome of high fiscal deficits and severe incidence of debt. Its annual fiscal deficit has stayed constantly at over 6 percent of GDP especially since 1990 [Pakistan (1997-98)]. The prevalence of such a high fiscal deficit over the years in a row has propelled increased borrowing from both internal and external sources to cover the resource gap. With inadequate improvement in the repayment capacity of the country debt has continued to accumulate at a massive rate. Serving as the cause and effect of each other, the volumes of both the fiscal deficit and debt have soared continuously. The most devastating consequence of high fiscal deficit and soaring debt has been the continuous accrual of massive debt-servicing. In fact, both the debt and debt-servicing have reached unaffordable limits. How to alleviate this situation has become the foremost issue of the country. While complete elimination of all the debt and thereby debt-servicing may not be easy to accomplish in the short run, efforts are needed to systematically bring the fiscal deficit down to a minimum affordable limit. What may be the minimum financeable level of fiscal deficit and how it may be reduced to that level are the issues addressed in this paper.
Modulational instability in binary spin-orbit-coupled Bose-Einstein condensates
We study modulation instability (MI) of flat states in two-component
spin-orbit-coupled (SOC) Bose-Einstein condensates (BECs) in the framework of
coupled Gross-Pitaevskii equations for two components of the pseudospinor wave
function. The analysis is performed for equal densities of the components.
Effects of the interaction parameters, Rabi coupling, and SOC on the MI are
investigated. In particular, the results demonstrate that the SOC strongly
alters the commonly known MI (immiscibility) condition, ,
for the binary superfluid with coefficients and of the
intra- and interspecies repulsive interactions. In fact, the binary BEC is
always subject to the MI under the action of the SOC, which implies that the
ground state of the system is plausibly represented by a striped phase
EAST: Energy Efficient Adaptive Scheme for Transmission in Wireless Sensor Networks
In this paper, we propose Energy-efficient Adaptive Scheme for Transmission
(EAST) in WSNs. EAST is IEEE 802.15.4 standard compliant. In this approach,
open-loop is used for temperature-aware link quality estimation and
compensation. Whereas, closed-loop feedback helps to divide network into three
logical regions to minimize overhead of control packets on basis of Threshold
transmitter power loss (RSSIloss) for each region and current number of
neighbor nodes that help to adapt transmit power according to link quality
changes due to temperature variation. Simulation results show that propose
scheme; EAST effectively adapts transmission power to changing link quality
with less control packets overhead and energy consumption compared to classical
approach with single region in which maximum transmitter power assigned to
compensate temperature variation
