Graphene based nanocomposites: synthesis and their theranostic applications
Venue: Journal of drug targeting
Year: 2018

Graphene, the mother of all carbon materials, has unlocked a new era of biomedical nanomaterials due to its exceptional biocompatibility, physicochemical and mechanical properties. It is a single atom thick, nanosized, two dimensional structure and provides high surface area with adjustable surface chemistry to form hybrids. The present article provides a comprehensive review of ever expanding application of graphene nanomaterials with different inorganic and organic materials in drug delivery and theranostics. Methods of preparation of nanomaterials are elaborated and biological and physicochemical characteristics of biomedical relevance are also discussed. Graphene form nanomaterials with metallic nanoparticles offer multiscale application. First, graphene act as a platform to attach nanoparticles and provide excellent mechanical strength. Second, graphene improves efficacy of metallic nanoparticles in diagnostic, biosensing, therapeutic and drug delivery application. Graphene based polymeric nanocomposites find wider application in drug delivery with flexibility to incorporate hydrophilic, hydrophobic, sensitive and macromolecules. In addition, grapheme quantum dots and graphene hybrids with inorganic nanocrystal and carbon nanotubes hybrids have shown interesting properties for diagnosis and therapy. Finally, we have pointed out research trends that may be more common in future for graphene based nanomaterials.
Inflammation and insulin resistance.
Venue: The Journal of clinical investigation
Year: 2006

Over a hundred years ago, high doses of salicylates were shown to lower glucose levels in diabetic patients. This should have been an important clue to link inflammation to the pathogenesis of type 2 diabetes (T2D) but the antihyperglycemic and antiinflammatory effects of salicylates were not connected to the pathogenesis of insulin resistance until recently. Together with the discovery of an important role for tissue macrophages, these new findings are helping to reshape thinking about how obesity increases the risk for developing T2D and the metabolic syndrome. The evolving concept of insulin resistance and T2D as having immunological components and an improving picture of how inflammation modulates metabolism provide new opportunities for using antiinflammatory strategies to correct the metabolic consequences of excess adiposity.
The role of water in structural changes of poly(N isopropylacrylamide) and poly(N isopropylmethacrylamide) studied by FTIR, Raman spectroscopy and quantum chemical calculations
Year: 2009

Temperature induced phase transition in water solutions of poly(N isopropylacrylamide) (PNIPAM) and poly(N isopropylmethacrylamide) (PNIPMAM) have been studied by ATR FTIR and Raman spectroscopy in combination with quantum chemical calculations. The presence or absence of the a methyl group has a strong effect on the physical structure of water solutions. Although the hydrophobic interactions for PNIPMAM and PNIPAM are very similar, PNIPMAM with additional methyl group exhibits significantly weaker intermolecular interactions between the amide groups. That effect is the cause of the higher transition temperature Tt by about 8 degC for PNIPMAM compared to PNIPAM due to the formation of larger compact structures. The presence of the methyl group is significant for the reversibility of the temperature transition during the backward cooling as the dissolution of more stable compact PNIPMAM requires overcoming of a higher energy barrier and shows a strong hysteresis.
Regeln, Willkur und der gute Ruf: Geldpolitik und Finanzmarkteffizienz in Deutschland, 14. bis 16. JahrhundertRules, Discretion or Reputation? Monetary Policies and the Efficiency of Financial Markets in Germany, 14th to 16th Centuries
Year: 2007

This paper examines the questions of whether and how feudal rulers were able to credibly commit to preserving monetary stability, and of which consequences their decisions had for the efficiency of financial markets. The study reveals that princes were usually only able to commit to issuing a stable coinage in gold, but not in silver. As for silver currencies, the hypothesis is that transferring the right of coinage to an autonomous city was the functional equivalent to establishing an independent central bank. An analysis of market performance indicates that financial markets between cities that were autonomous with regard to their monetary policies were significantly better integrated and more efficient than markets between cities whose currencies were supplied by a feudal ruler.
MIN: Co Governing Multi Identifier Network Architecture and Its Prototype on Operator's Network
Venue: IEEE Access
Year: 2020

IP protocol is the core of TCP/IP network layer. However, since IP address and its Domain Name are allocated and managed by a single agency, there are risks of centralization. The semantic overload of IP address also reduces its scalability and mobility, which further hinders the security. This paper proposes a co governing Multi Identifier Network (MIN) architecture that constructs a network layer with parallel coexistence of multiple identifiers, including identity, content, geographic information, and IP address. On the management plane, we develop an efficient management system using consortium blockchain with voting consensus, so the network can simultaneously manage and support by hundreds or thousands of nodes with high throughput. On the data plane, we propose an algorithm merging hash table and prefix tree (HTP) for FIB, which avoids the false negative error and can inter translate different identifiers with tens of billions of entries. Further, we propose a scheme to transport IP packets using CCN as a tunnel for supporting progressive deployment. We deployed the prototype of MIN to the largest operators' network in Mainland China, Hongkong and Macao, and demonstrated that the network can register identifier under co governing consensus algorithm, support VoD service very well.
Dissect the function of PKC in the formation of central supramolecular activation clusters and B cell activation (IRM8P.707)
Year: 2014

Protein kinase C (PKC) is a family of kinases encoded by nine genes with redundant and meanwhile distinct biological functions. One of such member, PKC, is abundantly expressed in B lymphocytes. However its roles in the formation of B cell immunological synapse (IS) and B cell activation are still unclear. Using a series of optical imaging based cell biological approaches, we showed that PKC was efficiently recruited to the B cell IS after antigen and B cell receptor (BCR) engagement. The proper distribution of PKC in IS is dependent on the bioactivity of PKC as mutant PKC in either constitutively activated or kinase dead format are unexpectedly extruded to peripheral region of IS. Over expression of WT PKC but not its mutants enhanced the contraction of BCR toward the central supramolecular activation clusters (cSMACs) as determined by the contact area and the BCR fluorescence intensity and the percentage of cSMAC formation. We also found that the strength of the initiation of BCR signaling cascade was potently influenced by PKC. The precise molecular mechanism of PKC to enhance the cSMAC formation and B cell activation will also be discussed.
Recommending Security Requirements for the Development of Android Applications Based on Sensitive APIs
Venue: IEEE Access
Year: 2020

App stores allow anyone to sell his products to millions of potential users. However, limited by the resources and time, some developers often focus on the functionalities of their Apps without well rounded considering security problems, which are more and more important for a successful product. In this paper, we propose an approach to help developers elicit security requirements by recommending related information gained from existing Apps in the marketplace. Firstly, we construct a feature framework to summarize functionalities of Apps by mining their descriptions with the method proposed in our previous work. Then, the sensitive APIs used in these Apps are extracted from their APK files and mapped with App features. Finally, we establish relationships between permissions and functionalities by taking sensitive APIs as a bridge, and design a recommendation framework to show information according to developers' demands from two aspects: the security requirements for the whole App and the ones for the given functionality. We evaluate our approach with 580 Apps from 5 categories on Google Play. The results confirm the usefulness of our approach, especially it can help new developers without experience initialize the security requirements and give mature developers supplementary information to elicit security requirements completely.

Reliability of Ultraviolet Light Emitting Diodes
Year: 2019

This chapter presents an extensive review of the literature on the degradation processes of GaN based UV A, UV B, and UV C LEDs. For the state of the art devices, the main open issue is the increase in Shockley Read Hall non radiative recombination inside the quantum well, originating from local generation of defects or from diffusion processes of dopant atoms or foreign impurities. Temperature acts as a significant acceleration factor, especially in lower wavelength devices, affected by a higher turn on voltage. Changes in the chemical structure of the package and of the encapsulant, induced by the high energy of the photons, may lead to a lower reflectivity and transmittance, thus limiting the overall reliability of the devices.
Managing Non Volatile Memory in Database Systems
Venue: SIGMOD Conference
Year: 2018

Non volatile memory (NVM) is a new storage technology that combines the performance and byte addressability of DRAM with the persistence of traditional storage devices like flash (SSD) While these properties make NVM highly promising, it is not yet clear how to best integrate NVM into the storage layer of modern database systems. Two system designs have been proposed. The first is to use NVM exclusively, i.e. to store all data and index structures on it. However, because NVM has a higher latency than DRAM, this design can be less efficient than main memory database systems. For this reason, the second approach uses a page based DRAM cache in front of NVM. This approach, however, does not utilize the byte addressability of NVM and, as a result, accessing an uncached tuple on NVM requires retrieving an entire page. In this work, we evaluate these two approaches and compare them with in memory databases as well as more traditional buffer managers that use main memory as a cache in front of SSDs. This allows us to determine how much performance gain can be expected from NVM. We also propose a lightweight storage manager that simultaneously supports DRAM, NVM, and flash. Our design utilizes the byte addressability of NVM and uses it as an additional caching layer that improves performance without losing the benefits from the even faster DRAM and the large capacities of SSDs.

Implementation of multimodal neonatal identification using Raspberry Pi 2
Venue: ICCIP
Year: 2016

Abduction, swapping and mix ups are the unfortunate events that could happen to newborn while in hospital premises and medical personnel are finding it difficult to curb this unfortunate incident. Traditional methods like birth ID bracelets and offline footprint recognition systems have their own drawbacks. Hence, a neonatalonline personal authentication system is proposed for this issue based on multimodal biometric system wherein footprint and palm print of neonatal is used for recognition. This concept is further enhanced by developing a prototype to be implemented on a Raspberry Pi 2 (a single board computer) In this paper, SIFT feature extraction, RANSAC algorithm for identification of matched interest points of palm print and footprint biometrics using OpenCV on Raspberry pi is implemented. The Raspberry Pi is a quad core ARM Cortex A7 application processor, System on chip (SoC) denoted as Broadcom BCM2836. It enhances performance, consumes less power, and reduces overall system cost and size. The Raspberry Pi is been controlled by a modified version of Debian Linux OS optimized for ARM architecture. The image recognition is performed using open source OpenCV 3.1.0 in Linux platform using CMake, g+ makefile. Thereby the proposed system improves the security system in hospitals birth centers and provides a low cost solution to the newborn swapping rather than the expensive DNA and HLA(Human Leukocyte Antigen)typing procedures. The efficiency(97.2% is high when multimodality is used than unimodality. This paper elucidates the research works carried on hardware as a biometric module to enhance the performance of a standalone device.
A comparative analysis of carbon emissions from online retailing of fast moving consumer goods
Year: 2015

Online retailing can lower the environmental impact of shopping under specific circumstances. As a result of the numerous variables involved, most of the studies that have compared the carbon footprints of online and conventional retailing only take a partial view. To make a more holistic assessment, this study develops a framework that accounts for all the relevant environmental factors relating to retail/e commerce activities. Variables related to consumer shopping behaviour such as basket size, transport mode, trip length and trip frequency are included in the analysis. This framework is used to build a Life Cycle Analysis model. The model is applied to different online retail methods for fast moving consumer goods in the United Kingdom. We find that, within the "last mile" link to the home, the nature of the consumer's behaviour in terms of travel, choice of e fulfilment method and basket size are critical factors in determining the environmental sustainability of e commerce. The nature and routing of van deliveries, the amount and type of packaging used, and the energy efficiency of shop and e fulfilment centre operations are also identified as significant contributors to climate change potential. The results of this study indicate ways in which e commerce can be made more environmentally sustainable, encouraging consumers to reduce complementary shopping trips and maximise the number of items per delivery. This study identifies the strengths and weaknesses of a range of e retail channels and provides a basis for future research on the environmental sustainability of online retailing of fast moving consumer goods.
Hidden Hamiltonian Cycle Recovery via Linear Programming
Venue: Oper. Res.
Year: 2020

We introduce the problem of hidden Hamiltonian cycle recovery, where there is an unknown Hamiltonian cycle in an $n$ vertex complete graph that needs to be inferred from noisy edge measurements. The measurements are independent and distributed according to \calP_n$ for edges in the cycle and \calQ_n$ otherwise. This formulation is motivated by a problem in genome assembly, where the goal is to order a set of contigs (genome subsequences) according to their positions on the genome using long range linking measurements between the contigs. Computing the maximum likelihood estimate in this model reduces to a Traveling Salesman Problem (TSP) Despite the NP hardness of TSP, we show that a simple linear programming (LP) relaxation, namely the fractional $2$ factor (F2F) LP, recovers the hidden Hamiltonian cycle with high probability as $n \to \infty$ provided that \alpha_n \log n \to \infty$ where \alpha_n \triangleq 2 \log \int \sqrt{d P_n d Q_n} is the R\'enyi divergence of order \frac{1}{2} This condition is information theoretically optimal in the sense that, under mild distributional assumptions, \alpha_n \geq (1+o(1) \log n$ is necessary for any algorithm to succeed regardless of the computational cost. Departing from the usual proof techniques based on dual witness construction, the analysis relies on the combinatorial characterization (in particular, the half integrality) of the extreme points of the F2F polytope. Represented as bicolored multi graphs, these extreme points are further decomposed into simpler "blossom type" structures for the large deviation analysis and counting arguments. Evaluation of the algorithm on real data shows improvements over existing approaches.
