Molecular‐beam epitaxy of Cd<sub><i>x</i></sub>Hg<sub>1−<i>x</i></sub>Te at D.LETI/LIR (1988)

To solve the problem of the high mercury consumption in the molecular‐beam epitaxy of CdxHg1−xTe, we present a special mercury cell and analyze the effect of the mercury flux on the cadmium and tellurium fluxes. On CdZnTe substrates, we have studied the influence of the substrate orientation on the growth defect density and the electrical properties of the epilayer. After n‐type annealing, the layers have a residual doping level higher than that of the liquid phase epitaxy layers. The lower carrier concentrations are obtained on layers grown on the (310) orientation which leads to a better crystal quality than on a (100) or (111) orientation. On alternative substrates, layers grown on (100) InSb substrate are indium doped. On (100) GaAs we show that misfit dislocations can be blocked near the GaAs interface by growing a multistepped composition buffer layer (MCBL). The MCBL is a stack of CdZnTe layers with different composition. It is shown that the dislocation blocking mechanism may occur when thickness of each individual layer is below its critical thickness.
Review on High‐Loading and High‐Energy Lithium–Sulfur Batteries (2017)

Abstract Owing to high specific energy, low cost, and environmental friendliness, lithium–sulfur (Li–S) batteries hold great promise to meet the increasing demand for advanced energy storage beyond portable electronics, and to mitigate environmental problems. However, the application of Li–S batteries is challenged by several obstacles, including their short life and low sulfur utilization, which become more serious when sulfur loading is increased to the practically accepted level above 3–5 mg cm −2 . More and more efforts have been made recently to overcome the barriers toward commercially viable Li–S batteries with a high sulfur loading. This review highlights the recent progress in high‐sulfur‐loading Li–S batteries enabled by hierarchical design principles at multiscale. Particularly, basic insights into the interfacial reactions, strategies for mesoscale assembly, unique architectures, and configurational innovation in the cathode, anode, and separator are under specific concerns. Hierarchy in the multiscale design is proposed to guide the future development of high‐sulfur‐loading Li–S batteries.
A Simple Robust Method for Estimating the Glucose Rate of Appearance from Mixed Meals (2012)

The presented technique for the estimation of R(a) showed excellent results when tested with simulated and actual clinical data. The simplicity of this new technique makes it suitable for large clinical research studies for the evaluation of the role of R(a) in patients with impairments in glucose metabolism. In addition, this technique is being used to build a model library of mixed meals that could be incorporated into diabetic subject simulators in order to account for more realistic and varied meals.
Fault detection and isolation in a DC microgrid using a central processing unit (2015)

The goal of this paper is to design a protection system capable of detecting, isolating and locating high and low impedance ground faults in a DC multi-terminal system using a Digital Signal Processing (DSP) based control unit. Due to low current fluctuations during faults, it becomes difficult to detect high impedance faults using conventional methods. In order to locate faults, the DC ring bus will be divided into different zones and an algorithm will be developed to monitor currents in each zone. The proposed method has been tested through examples and is seen to be cost effective and easy to implement.
A Data-Driven Methodology for Motivating a Set of Coherence Relations (1996)

The notion that a text is coherent in virtue of the `relations&apos; that hold between its component spans currently forms the basis for an active research programme in discourse linguistics. Coherence relations feature prominently in many theories of discourse structure, and have recently been used with considerable success in text generation systems. However, while the concept of coherence relations is now common currency for discourse theorists, there remains much confusion about them, and no standard set of relations has yet emerged. The aim of this thesis is to contribute towards the development of a standard set of relations. We begin from an explicitly empirical conception of relations: they are taken to model a collection of psychological mechanisms operative during the tasks of reading and writing. This conception is fleshed out with reference to psychological theories of skilled task performance, and to Rosch&apos;s notion of the basic level of categorisation. A methodology for investi...
Challenges of RERA: An analysis of New Reforms (2018)

Abstract Making it into the list with names like The United States of America, Germany, China, Singapore and UAE, India has finally received a green light. In contrast, where a developed country like US had it implemented in 1974, the time lag of 42 years in India raises a number of questions. After a long wait of 9 years, Real Estate Regulation and Development act, 2016 (RERA) has eventually come into force. With the act getting operational from May 1, 2017, it has already created a havoc amongst the builders and the developers of the country. Finally, after 70 years of independence and sovereignty, India has taken up a step, a step too bold to safeguard the interest and the rights of the common man. The panorama, sure too late, but has changed eventually and intends to mark the beginning of an era where the consumer will be the king. It properly entitles the work of each and every person involved. The various aspects of the act bring out every minor detail that one would require. Although RERA is launched and is in implementation, there are number of things what people are not aware about until now. In fact, majority of states are not yet ready and are still to appoint regulators. It is made mandatory for the states and UTs to set up the authority. However, only 13 states including Gujarat, Odisha, Andhra Pradesh, Uttar Pradesh, Madhya Pradesh, Maharashtra, Bihar and Union territories have so far been successful in reporting the rules. States which for time being are appointing interim authorities will have to create full-fledged bodies. Several parts of the country such as the north eastern states would have to be considered separately and may require different set of rules. In this paper, investigations are made into the present scenario, impending challenges and the impact of RERA in long run. There are various roles and definitions which are to be still made clear. This paper is very much useful for constructors, builders, policy makers and administrators. Keywords: Real estate, government policy, reforms Cite this Article Chauhan Krupesh A, Preety Tiwari.

Continuous Electrocardiographic Monitoring and Cardiac Arrest Outcomes in 8,932 Telemetry Ward Patients (2000)

Cardiac arrest is an uncommon event among telemetry ward patients, and monitor-signaled survivors are extremely rare. Routine telemetry offers little cardiac arrest survival benefit to most monitored patients, and a more selective policy for telemetry use might safely avoid ECG monitoring for many patients.
A Cloud-Based Monitoring System for Performance Assessment of Industrial Plants (2020)

The paper presents the realization of a control-loop performance monitoring system operating in a cloud as a single unity for the global supervision of data coming from various industrial plants located in different areas. This is a desirable solution for many companies, because of the costs of local installations (systems, human resources, and their maintenance and upgrading) and is made possible by available Industry 4.0 technologies, although some aspects are worthy of deeper investigation, depending on specific industrial realities. The monitoring system (PCU, Plant Check Up) is described in its basic components and its evolution toward the cloud-based configuration. The entire architecture, as well as the solutions adopted for data acquisition from the field, transmission to the cloud, and web app features, which allow a full remote monitoring, are illustrated. Technical details about the application on a pilot-scale plant are given, and results for significant cases and different types of loop and actuator status are presented.
Linking Knowledge Management and Innovation Culture for Business Performance Improvement (2016)

Purpose: To gain insights on how the linkages between knowledge management and innovation culture evolve in an organisation and that facilitate in making an impact on the business performance, and propose a conceptual model that captures the relationship between knowledge management, innovation culture, and business performance. Design/Methodology/Approach: A comprehensive review of previous literature and document analysis using secondary data method and reference of books, journals, industry reports, statistics, and different surveys undertaken for the purpose of the study to gain insights into the evolution of the linkages between knowledge management and innovation culture and its impact on business performance. Findings: The study clearly establishes that once the linkages between knowledge management and innovation culture evolve in organisations, then they have the potential to achieve breakthrough performances. It is also evident from the study of one of the organisations where the linkages evolved and matured, it resulted in launching of a new line of business, an exponential expansion in product offerings, and higher profitability. Based on the initial findings the extended literature review further reinforces that such linkages also exist in IT & Non IT organisations as well. Research Limitations/Implications: The conceptual paper evolved from the researcher's insights and experiences in the industry though initially the idea was unclear, however as the study progressed more insights obtained that resulted in proposing a conceptual model linking the KM, innovation culture, and business performance. Similar studies using the proposed model once performed on other organisations will provide further insights and enable to overcome implementation challenges. Practical Implications: The literature review points out that organisations tend to view KM initiatives in isolation, and as a result, failures are more and tend to be costly for organisations. A strong business case proposed to forge linkages between KM and innovation culture, which has enormous potential to create an impact on the business performance in organisations. The leadership of the organisation can also expect more success rate with the implementation of such a strategic initiative. Originality/Value: Surprisingly fewer research streams are available in the literature that investigates and integrates KM and innovation culture though individually each of the aspects discussed at length in the literature, and its implication on the performance of the organisation well understood. The proposed model will enable the organisations to tread a journey of integrating KM&Innovation culture, and may ultimately lead to more innovations and better business performance in the organisations.
Monitoring photopolymerization reactions with optical pyrometry (2003)

Abstract This article describes the development of optical pyrometry (OP) as a new analytical technique for the continuous monitoring of the progress of both free‐radical and cationic photopolymerizations. The method is rapid, reproducible, and very easy to implement. A temperature profile of a photopolymerization can be obtained. Preliminary studies have shown that the temperatures of some polymerizing monomers can easily reach temperatures in excess of 250 °C. The effects of the mass and reactivity of the monomer, light intensity, structures, and concentrations of the photoinitiators and monomers as well as the presence or absence of oxygen on various free‐radical and cationic photopolymerizations were examined with this method. Coupling of real‐time infrared spectroscopy with OP provides a convenient method for simultaneously monitoring both the chemical conversion and the temperature of a photopolymerization. This combined technique affords new insights into the effects of temperature‐induced autoacceleration on the course of photopolymerizations. © 2003 Wiley Periodicals, Inc.

OFDM-like High Order Backscatter Modulation (2018)

Backscatter communication has emerged as a promising technology for green communications and future IoT. This paper studies high order backscatter communication over OFDM carriers. For this purpose, a bank of four band-pass filters has been designed and implemented as well as four 4-QAM backscatter modulators. A prototype of the system is proposed which operate in four different frequencies, 2.39 GHz, 2.46 GHz, 2.57 GHz and 2.67 GHz. Further developments of this system could fulfill the promise of ambient backscatter communications over OFDM carriers in the air.
Characterization of the Cathepsin B Gene and Multiple mRNAs in Human Tissues: Evidence for Alternative Splicing of Cathepsin B Pre-mRNA (1993)

We have cloned and characterized multiple messages for cathepsin B that differ in their 5' and 3' untranslated regions (UTRs) from human kidney and the hepatoma cell line HepG2. A comparison of these messages with the cloned human cathepsin B gene reveals that they arise by alternative splicing of a single gene. Processing at a cryptic intron donor site in exon 11 and splicing to exon 12 produces a 4.0-kb message with an alternate 3' UTR in addition to the 2.3-kb message described previously by Chan et al. (1986). Variable removal of exon 2 produces cathepsin B mRNAs which differ by 88 nucleotides in their 5'-UTRs. The ratio of the 2.3-kb to 4.0-kb transcript is about 2:1 in most of the tissues examined, but the ratio of mRNAs with variant 5' UTRs differs widely. Cathepsin B mRNAs lacking exon 2 are predominant in human tumors. In addition, human breast and colon carcinomas and a human melanoma contain a cathepsin B transcript that is also missing exon 3 encoding the signal peptide and 7 residues of the activation propeptide. An in vitro transcription/translation assay was used to demonstrate that this message could be translated from an internal methionine codon (residue 52), producing a 32-kD product lacking the signal peptide and more than half the propeptide. The transcription/translation assay also demonstrated that the variant messages differ in their rates of translation. The relative rates are about 8:2:1 for mRNA lacking exons 2 and 3 compared to mRNA lacking exon 2 and mRNA containing the full-length 5' end, respectively. These results suggest that the expression of cathepsin B in human tissues may be regulated in part at the level of mRNA processing.
Large-scale graph analytics in Aster 6 (2014)

Graph analytics is an important big data discovery technique. Applications include identifying influential employees for retention, detecting fraud in a complex interaction network, and determining product affinities by exploiting community buying patterns. Specialized platforms have emerged to satisfy the unique processing requirements of large-scale graph analytics; however, these platforms do not enable graph analytics to be combined with other analytics techniques, nor do they work well with the vast ecosystem of SQL-based business applications. Teradata Aster 6.0 adds support for large-scale graph analytics to its repertoire of analytics capabilities. The solution extends the multi-engine processing architecture with support for bulk synchronous parallel execution, and a specialized graph engine that enables iterative analysis of graph structures. Graph analytics functions written to the vertex-oriented API exposed by the graph engine can be invoked from the context of an SQL query and composed with existing SQL-MR functions, thereby enabling data scientists and business applications to express computations that combine large-scale graph analytics with techniques better suited to a different style of processing. The solution includes a suite of pre-built graph analytic functions adapted for parallel execution.
A time-interleaved flash-SAR architecture for high speed A/D conversion (2009)

A time-interleaved flash-SAR ADC architecture has been suggested for high speed A/D conversion. Owing to the MSBs determined by the front end flash ADC, SAR ADC completes the A/D conversion in a reduced number of cycles. Time-interleaved SAR ADCs with a commonly shared low resolution flash ADC provide a new size and power efficient high speed ADC architecture. The proposed ADC structure has been verified by developing a behavioral model of a 6-bit 1.2 GHS/s ADC. Circuit design considerations have also been discussed based on the sampling network mismatch between the flash and SAR ADCs.
Functional Deletion of the Calcium-Sensing Receptor in a Case of Neonatal Severe Hyperparathyroidism (2004)

Heterozygous inactivating mutations of the calcium-sensing receptor (CaR) cause familial hypocalciuric hypercalcemia, whereas homozygous or compound heterozygous inactivating mutations normally cause neonatal severe hyperparathyroidism. In a case of neonatal severe hyperparathyroidism characterized by moderately severe hypercalcemia and very high PTH levels, coupled with evidence of hyperparathyroidism and effects on brain development not previously demonstrated, we detected point mutations on separate alleles of the CaR, resulting in premature stop codon substitutions at G94 and R648. This led to severely truncated receptors and an effective so-called knockout of functional CaR. FLAG-tagged, truncated receptors were expressed in HEK293 cells for functional analysis. Confocal microscopy demonstrated cytoplasmic localization of the G94stop receptor, whereas the R648stop receptor was present both in the cytoplasm and associated with the cell membrane. Only the R648stop receptor could be detected by Western analysis. Functional assays in which R648stop and wild-type receptor were cotransfected into HEK293 cells demonstrated a reduction in wild-type Ca(2+)-responsiveness by the R648stop receptor, even at physiological Ca(2+) levels, thus simulating familial hypocalciuric hypercalcemia in relatives of the infant who were heterozygous for the R648stop mutation. The R648stop receptor alone was nonresponsive to Ca(2+). This case contributes to our understanding of the clinical manifestation of a CaR knockout.
On-line real-time path planning of mobile robots in dynamic uncertain environment (2006)

A new path planning method for mobile robots in globally unknown environment with moving obstacles is presented. With an autoregressive (AR) model to predict the future positions of moving obstacles, and the predicted position taken as the next position of moving obstacles, a motion path in dynamic uncertain environment is planned by means of an on-line real-time path planning technique based on polar coordinates in which the desirable direction angle is taken into consideration as an optimization index. The effectiveness, feasibility, high stability, perfect performance of obstacle avoidance, real-time and optimization capability are demonstrated by simulation examples.
Optical resonance modes in GaN pyramid microcavities (1999)

An array of GaN hexagonal pyramids with a side length of 8.0 μm was fabricated by selective epitaxial overgrowth. These microsized pyramids are highly efficient microcavities. Three types of optical resonance modes with mode spacings of 10, 5.0, and 6.0 Å were observed when a single pyramid was pumped optically by an intense ultraviolet laser beam. An optical ray tracing method has been developed for calculating the optical resonance modes inside the pyramid microcavities. It was shown that a single pyramidal cavity can support several different types of optical resonance modes. The calculated mode spacing agrees very well with the observations. The uniqueness and advantages of this class of hexagonal pyramidal microcavities over the other microcavities are discussed. The implications of our finding on the future GaN microcavity light emitters including micro-light-emitting diodes, microcavity lasers, and vertical-cavity-surface emitting lasers are also discussed.
Residual Chlorine Distribution and Disinfection during Electrochemical Removal of Dilute Ammonia from an Aqueous Solution. (2002)

Experiments on the electrochemical oxidation of ammonia in artificial seawater are carried out in a lab-scale electrochemical apparatus. The operating parameters are current density (16–66 A/m2) and hydraulic residence time in a reactor (30–90 sec). The ammonia concentration in the effluent of the reactor exponentially decreases with increasing the current density and the hydraulic residence time, while the concentration of chlorine residuals increases. Most of the chlorine residuals are free available chlorine and the remainder is dichloramine. A strong disinfection characteristic can be seen during electrochemical treatment of ammonia.
pH-responsive release of chlorhexidine from modified nanoporous silica nanoparticles for dental applications (2016)

Abstract A pH-sensitive stimulus-response system for controlled drug release was prepared by modifying nanoporous silica nanoparticles (NPSNPs) with poly(4-vinylpyridine) using a bismaleimide as linker. At physiological pH values, the polymer serves as gate keeper blocking the pore openings to prevent the release of cargo molecules. At acidic pH values as they can occur during a bacterial infection, the polymer strains become protonated and straighten up due to electrostatic repulsion. The pores are opened and the cargo is released. The drug chlorhexidine was loaded into the pores because of its excellent antibacterial properties and low tendency to form resistances. The release was performed in PBS and diluted hydrochloric acid, respectively. The results showed a considerably higher release in acidic media compared to neutral solvents. Reversibility of this pH-dependent release was established. In vitro tests proved good cytocompatibility of the prepared nanoparticles. Antibacterial activity tests with Streptococcus mutans and Staphylococcus aureus revealed promising perspectives of the release system for biofilm prevention. The developed polymer-modified silica nanoparticles can serve as an efficient controlled drug release system for long-term delivery in biomedical applications, such as in treatment of biofilm-associated infections, and could, for example, be used as medical implant coating or as components in dental composite materials.
Analysis of assumption about the possibility of the highly effective scenario of in-flight muon catalyzed fusion (2021)

It is shown that an average number of in-flight fusion reactions catalyzed by one negative muon in the reactor proposed by Iiyoshi et al. [AIP Conf. Proc. 2179, 020010 (2019)] will be less than 120 rather than about 1000, and therefore, the efficiency of the use of this reactor for practical purposes will be much less than expected earlier.
Incorporation of Poly[(<scp><i>R</i></scp>)‐3‐hydroxybutyrate] into Cationic Copolymers Based on Poly(2‐(dimethylamino)ethyl methacrylate) to Improve Gene Delivery (2013)

The synthesis and gene transfection efficiency of a series of novel amphiphilic triblock copolymers with two hydrophilic poly(2-(dimethylamino)ethyl methacrylate) (DMAEMA) blocks flanking a central hydrophobic poly[(R)-3-hydroxybutyrate] (PHB) block is reported. These copolymers have significantly lower toxicity compared to the polyethyleneimine (PEI) and PDMAEMA homopolymer. Unexpectedly, the incorporation of PHB significantly improves the gene transfection efficiency as compared to PEI or PDMAEMA homopolymers.
