Cancer biomarker development from basic science to clinical practice
The amount of published literature on biomarkers has exponentially increased
over the last two decades. Cancer biomarkers are molecules that are either part
of tumour cells or secreted by tumour cells. Biomarkers can be used for diagnosing
cancer (tumour versus normal and differentiation of subtypes), prognosticating
patients (progression free survival and overall survival) and predicting
response to therapy. However, very few biomarkers are currently used in clinical
practice compared to the unprecedented discovery rate. Some of the examples
are: carcino-embryonic antigen (CEA) for colon cancer; prostate specific antigen
(PSA) for prostate; and estrogen receptor (ER), progesterone receptor (PR) and
HER2 for breast cancer.
Cancer biomarkers passes through a series of phases before they are used in
clinical practice. First phase in biomarker development is identification of biomarkers
which involve discovery, demonstration and qualification. This is followed
by validation phase, which includes verification, prioritisation and initial
validation. More large-scale and outcome-oriented validation studies expedite
the clinical translation of biomarkers by providing a strong âevidence baseâ. The
final phase in biomarker development is the routine clinical use of biomarker.
In summary, careful identification of biomarkers and then validation in well-designed
retrospective and prospective studies is a systematic strategy for developing
clinically useful biomarkers
CPEC: A TOOL FOR REGIONAL INTEGRATION AND LIBERAL INSTITUTIONALISM
oai:ojs2.margallapapers.edu.pk:article/2China-Pakistan Economic Corridor (CPEC) has been visualized by political scientists as a structural change in the balance of power of the world. The corridor has far-reaching economic and geopolitical impacts on Southwest Asian countries in general and Pakistan in particular. CPEC, being a transnational project, may face challenges in geographic as well as human terrain during its implementation phase. It would involve extra ordinary engineering resources to execute, massive funds to realize, and political acumen to manage social elements of Southwest Asian countries. This paper, therefore, explores Chinaâs evolving relationship with the international system to achieve accelerated infrastructure development and boosted socio-economic growth through regional integration and liberal institutionalism. It is a multilateral strategy that will help Pakistan realize its true potential in the economic and strategic domains. It also endeavors to find linkages between Chinaâs multilateralism with regional integration under the framework of CPEC based on liberal values of connectivity.

Exploiting peer group concept for adaptive and highly available services
This paper presents a prototype for redundant, highly available and fault
tolerant peer to peer framework for data management. Peer to peer computing is
gaining importance due to its flexible organization, lack of central authority,
distribution of functionality to participating nodes and ability to utilize
unused computational resources. Emergence of GRID computing has provided much
needed infrastructure and administrative domain for peer to peer computing. The
components of this framework exploit peer group concept to scope service and
information search, arrange services and information in a coherent manner,
provide selective redundancy and ensure availability in face of failure and
high load conditions. A prototype system has been implemented using JXTA peer
to peer technology and XML is used for service description and interfaces,
allowing peers to communicate with services implemented in various platforms
including web services and JINI services. It utilizes code mobility to achieve
role interchange among services and ensure dynamic group membership. Security
is ensured by using Public Key Infrastructure (PKI) to implement group level
security policies for membership and service access.Comment: The Paper Consists of 5 pages, 6 figures submitted in Computing in

Interpreting the Legal Archive of Visual Transformations: Textual Articulations of Visibility in Evidentiary Procedures and Documentary Formats of Colonial Law
This article is concerned with tracing an onto-epistemological break through the archeology of colonial penal law, whereby a historical restructuring of the âvisibleâ and the âarticulableâ produces modern ways of âseeingâ and âknowing.â This epistemic break will be investigated through eighteenth and nineteenth century âRegulationâ of Islamic sharÄ«Êża penal law by British administrators of the East India Company in colonial Bengal. The juridico-discursive body, which came to be known as Anglo-Muhammadan law, will be analyzed through court records compiled by Company jurists and their Regulations modifying sharÄ«Êża jurisprudence. Islamic penal law is based on hermeneutical practices of juridical reasoning formed through particular ways of seeing, knowing, and verifying the truth through eye-witness and testimony. In this article I will show that when the British commandeered this system of justice towards their own ends, the regulatory changes they instituted inadvertently brought about visual transformations of the ways in which legal life-worlds of the colony come to be recorded, articulated, and expressed. Under the British administration of colonial Bengal, this dual-process of appropriation and subversion of the law took shape through translation and transliteration of fiqh treatises, to legal amendments and sweeping legislations in substantive law. This process not only provided colonial power access to the bodies of colonial subjects, but also conditioned the relations between criminality, visuality, and juridical veridiction through penal legislation. As this article will show, the East India Companyâs regulation of Islamic penal law began incorporating modern forms of evidentiary proofs, indexicality, and documentary formats that restructured the lifeworld of colonial law in 19th century Bengal
Syncretic Architecture of Fatehpur Sikri: a Symbol of Composite Culture
The amalgamation of native Indians and Muslim immigrants eventuated in a prolific way in the realm of literature, art, music, technology and especially in architecture, which reached at its zenith during Mughal period. Akbar, the great Mughal, is greatly recognized for his syncretism and religious tolerance. With the power of his influential personality and eclectic approach, he unified the various artistic traditions and architectural styles in the design of his new capital city, Fatehpur Sikri. Although, the architectural forms and construction techniques involved in the design of city had already been incorporated since the arrival of Islam in Indian subcontinent, but their synthesis reached at its zenith at Fatehpur Sikri and thus traditionally rich and fanciful Indian style was merged with the lightness and simplicity of Islamic style. This paper will focus on the unique intermingling of two entirely different styles like their cultures which were born in different regions and with different approaches. This fusion developed a new style in architecture besides several other aspects of life in India
Interpretation of Modified Electromagnetic Theory and Maxwell's Equations on the Basis of Charge Variation
Electromagnetic waves are the analytical solutions of Maxwell's equations that represent one of the most elegant and concise ways to state the fundamentals of electricity and magnetism. From them one can develop most of the working relationships in the electric and magnetic fields. Considering deeply the effect of charge variation in Maxwellâs equations for time varying electric and magnetic fields of charges in moving inertial frame, the magnitude of charge particles vary according to Asifâs equation of charge variation. Consequently the Maxwellâs equations give different results to an observer measuring at rest. This research paper explained the effect of charge variation in Classical Electromagnetic theory, Maxwellâs equations, Coulumbâs law, Lorentz force law when we are referring to any inertial frame.DOI:http://dx.doi.org/10.11591/ijece.v4i2.535
Design and Code Optimization for Systems with Next-generation Racetrack Memories
With the rise of computationally expensive application domains such as machine learning, genomics, and fluids simulation, the quest for performance and energy-efficient computing has gained unprecedented momentum. The significant increase in computing and memory devices in modern systems has resulted in an unsustainable surge in energy consumption, a substantial portion of which is attributed to the memory system. The scaling of conventional memory technologies and their suitability for the next-generation system is also questionable. This has led to the emergence and rise of nonvolatile memory ( NVM ) technologies. Today, in different development stages, several NVM technologies are competing for their rapid access to the market.
Racetrack memory ( RTM ) is one such nonvolatile memory technology that promises SRAM -comparable latency, reduced energy consumption, and unprecedented density compared to other technologies. However, racetrack memory ( RTM ) is sequential in nature, i.e., data in an RTM cell needs to be shifted to an access port before it can be accessed. These shift operations incur performance and energy penalties. An ideal RTM , requiring at most one shift per access, can easily outperform SRAM . However, in the worst-cast shifting scenario, RTM can be an order of magnitude slower than SRAM .
This thesis presents an overview of the RTM device physics, its evolution, strengths and challenges, and its application in the memory subsystem. We develop tools that allow the programmability and modeling of RTM -based systems. For shifts minimization, we propose a set of techniques including optimal, near-optimal, and evolutionary algorithms for efficient scalar and instruction placement in RTMs . For array accesses, we explore schedule and layout transformations that eliminate the longer overhead shifts in RTMs . We present an automatic compilation framework that analyzes static control flow programs and transforms the loop traversal order and memory layout to maximize accesses to consecutive RTM locations and minimize shifts. We develop a simulation framework called RTSim that models various RTM parameters and enables accurate architectural level simulation.
Finally, to demonstrate the RTM potential in non-Von-Neumann in-memory computing paradigms, we exploit its device attributes to implement logic and arithmetic operations. As a concrete use-case, we implement an entire hyperdimensional computing framework in RTM to accelerate the language recognition problem. Our evaluation shows considerable performance and energy improvements compared to conventional Von-Neumann models and state-of-the-art accelerators
