Security in Next Generation Mobile Payment Systems: A Comprehensive Survey (2021)

Cash payment is still king in several markets, accounting for more than 90% of the payments in almost all the developing countries. The usage of mobile phones is pretty ordinary in this present era. Mobile phones have become an inseparable friend for many users, serving much more than just communication tools. Every subsequent person is heavily relying on them due to multifaceted usage and affordability. Every person wants to manage his/her daily transactions and related issues by using his/her mobile phone. With the rise and advancements of mobile-specific security, threats are evolving as well. In this paper, we provide a survey of various security models for mobile phones. We explore multiple proposed models of the mobile payment system (MPS), their technologies and comparisons, payment methods, different security mechanisms involved in MPS, and provide analysis of the encryption technologies, authentication methods, and firewall in MPS. We also identify current challenges and future directions of mobile phone security.
Tumour treating fields therapy for glioblastoma: current advances and future directions (2020)

Glioblastoma multiforme (GBM) is the most common primary brain tumour in adults and continues to portend poor survival, despite multimodal treatment using surgery and chemoradiotherapy. The addition of tumour-treating fields (TTFields)-an approach in which alternating electrical fields exert biophysical force on charged and polarisable molecules known as dipoles-to standard therapy, has been shown to extend survival for patients with newly diagnosed GBM, recurrent GBM and mesothelioma, leading to the clinical approval of this approach by the FDA. TTFields represent a non-invasive anticancer modality consisting of low-intensity (1-3 V/cm), intermediate-frequency (100-300 kHz), alternating electric fields delivered via cutaneous transducer arrays configured to provide optimal tumour-site coverage. Although TTFields were initially demonstrated to inhibit cancer cell proliferation by interfering with mitotic apparatus, it is becoming increasingly clear that TTFields show a broad mechanism of action by disrupting a multitude of biological processes, including DNA repair, cell permeability and immunological responses, to elicit therapeutic effects. This review describes advances in our current understanding of the mechanisms by which TTFields mediate anticancer effects. Additionally, we summarise the landscape of TTFields clinical trials across various cancers and consider how emerging preclinical data might inform future clinical applications for TTFields.

Mixed-signal circuit simulation system with behavioral modeling capability (1994)

In this paper, the development of a mixed-signal circuit simulation system with behavioral modeling capability is discussed. In this context, mixed-signal simulation refers to the simulation of circuits and systems containing both analog and digital cells excited with signals of either an analog or digital nature. The background information regarding circuit simulation is given along with a discussion of device and system modeling for analog and digital cells. In addition, the numerical methods and programming techniques along with how these relate to the internal data structure are analyzed. Finally, the scenarios used for testing the simulator are discussed and the results compared to results obtained from the SPICE simulator using device based models. The development of this simulation system has provided a seamless method for developing behavioral models given a cell which has been well characterized. These behavioral models are developed utilizing object-oriented programming techniques and are capable of providing highly accurate results. Behavioral cells, once developed, can then be simulated with signals and cells of an analog or digital nature to provide significant improvements in simulation times of large systems.
Measurement of Protein Hydrophobicity (2003)

Abstract Among numerous methods reported in the literature for analysis of protein hydrophobicty, the only methods of potential use for routine food analysis were chosen here. The most popular methods are probe spectrofluorometry using ANS, CPA, DPH, and Prodan. Additional methods selected were SDS binding, hydrophobic interaction chromatography, contact angle, and hydrophobic partition. All methods are relatively easy to conduct when need has arisen to confirm controversial data, such as those obtained by using probe spectrofluorometry. Advantages and disadvantages of different methods are compared. Importance of the relationships with functionality of proteins in food processing is emphasized because the true meaning of surface hydrophobicity of proteins is difficult to define.
Tunable Electroacoustic Resonators through Active Impedance Control of Loudspeakers (2012)

The current trend for multipurpose rooms requires enhanced acoustic treatments capable to meet ever more demanding specifications in terms of performance, compactness and versatility. The reason is the variety of activities to be hosted and the corresponding requirements in terms of acoustic quality which may be very different and even conflicting. In any process to improve listening comfort, the treatment of low-frequency sound is a major concern. The problem stems from the proven ineffectiveness of passive soundproofing solutions of the state of the art, or from their bulkiness that may be prohibitive. This thesis focuses on the analysis, design, realization and characterization of tunable electroacoustic resonators intended to specifically address this issue. This concept deals with loudspeakers, the acoustic impedance of which can be easily adjusted in a controlled fashion. Creating an electroacoustic resonator out of a loudspeaker is the result of an interdisciplinary effort. Such a challenging task combines conceptual tools, models, and applied solutions, drawing from the fields of audio engineering, control theory, and electrical engineering, both in the analog and digital domains. A unifying theory is introduced, covering different strategies from passive electrical shunt to active control of acoustic impedance in a single formalism. This research shows that achieving a desired acoustic impedance at the transducer diaphragm is equivalent to the implementation of a specific functional relationship between the electrical current and voltage across the transducer terminals, and vice versa. From a design perspective, the specific electrical load is tailored by using an internal model of the transducer. The result is an innovative model-based synthesis methodology where the active control of acoustic impedance is reformulated as an electrical impedance synthesis, thus removing the use of sensor. This concept opens new opportunities to improve listening spaces by providing efficient acoustic absorption at low frequencies. Experiments clearly show the benefits of the proposed methodology in a field where there is currently no competitive solution. It is believed that the technological advances resulting from the coupling of a loudspeaker with a synthetic load should pave the way to innovative techniques in noise control and, hopefully, stimulate research in related areas.
Co-purification and characterization of ATP-sulfurylase and adenosine-5'-phosphosulfate kinase from rat chondrosarcoma. (1987)

The two sulfate-activating enzymes, ATP-sulfurylase (EC 2.7.7.4) and adenosine-5'-phosphosulfate kinase (adenylylsulfate kinase, EC 2.7.1.25),were each purified about 2000-fold from crude rat chondrosarcoma homogenate.Throughout a purification protocol which included Sephacryl S-300 gel filtration, DEAE-Sephadex ion exchange, hydroxylapatite, and ATPagarose affinity chromatography, these two activities consistently co-purified.ATP-sulfurylase and adenosine-5'-phosphosulfate kinase each showed a pH optima of 7.0-7.4and a bimodal temperature optima of 46 and 52-54 "C.Both activities preferred Mg2+ as their divalent cation source over Mn2+, Co2+, or Zn2+.The apparent K , values determined for adenosine 5'phosphosulfate in both assays was 1-5 WM; the K,,, for pyrophosphate in the sulfurylase reaction was 40 p~ and for ATP in the kinase reaction was 5 mM.Gel electrophoresis indicated major bands at M, = 160,000 in nondenaturing systems and 35,000-37,000 and 60,000 under dissociative conditions, whereas gel filtration of the most highly purified fractions yielded a coincident peak in the molecular weight range 260,000.The activation of inorganic sulfate is the result of the concerted action of the two enzymes ATP-sulfurylase (EC 2.7.7.4) and APS' kinase (adenylylsulfate kinase, EC 2.7.1.25)(1) as follows.ATP-sulfurylase ATP + SO:--.APS + PPi
Coix seed extract, A commonly used treatment for cancer in china, inhibits NFκB and protein kinase C signaling (2007)

A pharmaceutical grade extract of Coix lachryma-jobi seeds is currently the most commonly used treatment for cancer in China. Although clinical data support the use of this preparation of a Traditional Chinese Medicine for cancer treatment, biological basis for the activity of this preparation has not been previously established. To address this issue, we first evaluated the anti-neoplastic activity of a Coix extract emulsion in xenografts of MDA-MB-231 breast cancer cells and found that the extract significantly inhibits growth of MDA-MB-231 xenografts in athymic nude mice. Using oligonucleotide microarrays, we determined that Coix seed extract also significantly affects gene expression in these cells, including downregulation of genes (such as COX-2 and matrixmetalloproteinases) that are considered to be important in neoplasia. The specific gene expression changes noted after Coix seed extract treatment are characteristic of inhibition of NFkappaB-dependent transcription, leading us to evaluate how the treatment affects that pathway. An NFkappaB-dependent reporter assay demonstrated dose-dependant inhibition of NFkappaB signaling by treatment of cultures with the extract, and immunofluorescent microscopy found that these effects are associated with reduced translocation of the Rel-A/p65 subunit of NFkappaB to the nucleus. Coix extract also inhibits activity of protein kinase C, a major mediator of signal transduction and activator of NFkappaB. Thus, this Traditional Chinese Medicine-based cancer treatment affects cellular pathways of recognized importance in neoplasia.

Efficacy of moxidectin, ivermectin and albendazole oral drenches for suppression of periparturient rise in ewe worm egg output and reduction of anthelmintic treatment for lambs (1997)

Sixty multiparous crossbred ewes which had lambed within three days in the first week of April 1996, were divided into four groups. Each group consisted of 15 ewes plus 12 pairs of twins and three single lambs. Group 1 was left untreated, group 2 was treated with albendazole 2.5 per cent drench, group 3 received moxidectin 0.1 per cent drench and group 4 received ivermectin 0.08 per cent drench. The ewes in each group were dosed with their anthelmintic on April 4 (day 0) before being turned out to separate equal-sized paddocks within the same field on the following morning. The field had been used for grazing sheep annually for many years and was considered to be contaminated with infective larvae of the common gastrointestinal nematodes infecting sheep in the region. Faecal samples were collected every two weeks from the ewes and lambs until July 25 (day 112). The lambs in each group were dosed with the anthelmintic used for their dams on day 42, and the dose was repeated when more than 50 per cent of the lambs in any group had a faecal egg count of more than 200 eggs per gram (epg). The total faecal egg output of the treated ewes over days 14 to 70, compared with that of the untreated control group, was reduced by 78.9 per cent by the moxidectin drench, by 47.6 per cent by ivermectin, and by 21.5 per cent by albendazole. The lambs in the groups treated with moxidectin and ivermectin required only one treatment on day 42 before reaching finishing weight; those in the albendazole-treated group were treated twice and the control group once. The faecal egg outputs of the lambs from day 42 until the end of the experiment on day 112 were reduced by 75 per cent by the moxidectin drench, by 48.5 per cent by ivermectin, and by 9 per cent by albendazole. There were no significant differences between the rates of weight change of either ewes or lambs in any of the groups.
Bentonite Used As a Host-Matrix in the Study of Ester Hydrolysis (2015)

In this paper results obtained on the kinetics of ester adsorption on raw, acid treated and pre-heated bentonite have been presented. The infra-red profiles and the XRF spectra of the raw and acid activated bentonite have also been discussed. The change in properties of bentonite on heating and acidification are shown to affect its adsorption characteristics. The adsorption efficiencies of bentonite are high, enhanced on acidification but diminished with pre-heating. Infra-red spectra shows that the C=O stretching vibration of the adsorbed molecules shifted to lower frequencies compared with the carbonyl band at 1700cm -1 in the spectra of pure esters. The Lewis and Bronsted acid sites on the raw and acidified bentonite samples were also identified from the spectra of ethyl acetate adsorbed on the raw and acidified samples. Quantitative elemental analysis of the raw and acid treated bentonite shows changes in the amounts of cations on acidification.
Mobile Enterprise A Case Study of Enterprise Service Integration (2009)

A mobile enterprise can be established in a cellular network by participating mobile hosts, which provide Web services from smart phones, and their clients. Mobile hosts enable seamless integration of user-specific services to the enterprise, by following the Web service interfaces and standards, also on the radio link. Moreover, services provided by the mobile host can be integrated with larger enterprise services, bringing added value to the mobile services. However, establishing such a mobile enterprise poses several technical challenges, like the quality of service (QoS) and discovery aspects, for the network and as well as for mobile phone users. The paper summarizes the challenges and research in this domain, along with a case study where the results have been applied. The study and the results are of significant value in the enterprise service integration domain.

An Anonymity and Authentication Mechanism for Internet of Things (2011)

Authentication has received increasing attention in the literatures of Internet of Things. At the same time, numerous concerns have been raised about the issue of anonymity due to users’ awareness of their privacy nowadays. How to achieve trade-off between anonymity and certification simultaneously? In this paper, we propose a security architecture to ensure anonymity and certification for Internet of Things. We use pseudonym and threshold secret sharing approach to resolve conflict between anonymity and certification. Moreover, the implementation of Bloom filter offers security authentication for remote command. Security analysis shows that the proposed mechanism can perfectly achieve tradeoff between anonymity, certification, and also resist impersonation, tamper as well as compromise attacks.

Risk Factors for Human Infection with Avian Influenza A H5N1, Vietnam, 2004 (2006)

To evaluate risk factors for human infection with influenza A subtype H5N1, we performed a matched case-control study in Vietnam. We enrolled 28 case-patients who had laboratory-confirmed H5N1 infection during 2004 and 106 age-, sex-, and location-matched control-respondents. Data were analyzed by matched-pair analysis and multivariate conditional logistic regression. Factors that were independently associated with H5N1 infection were preparing sick or dead poultry for consumption < or =7 days before illness onset (matched odds ratio [OR] 8.99, 95% confidence interval [CI] 0.98-81.99, p = 0.05), having sick or dead poultry in the household < or =7 days before illness onset (matched OR 4.94, 95% CI 1.21-20.20, p = 0.03), and lack of an indoor water source (matched OR 6.46, 95% CI 1.20-34.81, p = 0.03). Factors not significantly associated with infection were raising healthy poultry, preparing healthy poultry for consumption, and exposure to persons with an acute respiratory illness.
Modified phosphate ceramics for stabilization and solidification of salt mixed wastes. (1998)

Novel chemically bonded phosphate ceramics have been investigated for stabilization and solidification of chloride and nitrate salt wastes. Using low-temperature processing, we stabilized and solidified chloride and nitrate surrogate salts (with hazardous metals) in magnesium potassium phosphate ceramics up to waste loadings of 70-80 wt.%. A variety of characterizations, including strength, microstructure, and leaching, were then conducted on the waste forms. Leaching tests show that all heavy metals in the leachant are well below the EPAs universal treatment standard limits. Long-term leaching tests, per ANS 16. 1 procedure, yields leachability index for nitrate ions > 12. Chloride ions are expected to have an even higher (i.e., better) leachability index. Structural performance of these final waste forms, as indicated by compression strength and durability in aqueous environments, satisfies the regulatory criteria. Thus, based on the results of this study, it seems that phosphate ceramics are viable option for containment of salt wastes.
Antibacterial Activity of Licochalcone A against Spore-Forming Bacteria (2002)

Licochalcone A was isolated from the roots of licorice, Glycyrrhiza inflata, which has various uses in the food and pharmaceutical industries; isolation was followed by extraction with ethanol and column chromatography with silica gel. In this study, the activities of licochalcone A against some food contaminant microorganisms were evaluated in vitro. The vegetative cell growth of Bacillus subtilis was inhibited in a licochalcone A concentration-dependent manner and was completely prevented by 3 micrograms of licochalcone A/ml. Licochalcone A showed a high level of resistance to heating at 80 to 121 degrees C for 15 min. Licochalcone A did not inhibit the germination of heat-treated spores of B. subtilis induced by L-alanine. Licochalcone A showed effects against all gram-positive bacteria tested and especially was effective against all Bacillus spp. tested, with MICs of 2 to 3 micrograms/ml, but was not effective against gram-negative bacteria or eukaryotes at 50 micrograms/ml. Although the cationic antimicrobial peptides protamine and epsilon-poly-L-lysine resulted in the loss of antimicrobial activity in the presence of either 3% (wt/vol) NaCl or protease at 20 micrograms/ml, the antibacterial activity of licochalcone A was resistant to these conditions. Thus, licochalcone A could be a useful compound for the development of antibacterial agents for the preservation of foods containing high concentrations of salts and proteases, in which cationic peptides might be less effective.
Relationships between Sport Achievement Orientation and Competitive State Anxiety (1992)

This study examined the relationship between sport achievement orientation and cognitive anxiety, somatic anxiety, and self-confidence in a sample of male ( n =60) track and field athletes. Subjects responded to the Competitive State Anxiety Inventory-2 (CSAI-2) on five occasions during the precompetition period and also completed the Sport Orientation Questionnaire (SOQ). Stepwise multiple-regression analyses were employed in order to determine whether any of the SOQ subscales emerged as significant predictors of the CSAI-2 subscale scores. The dominant predictor to emerge for each anxiety subcomponent was the competitiveness subscale. The subjects were then dichotomized into high and low groups of competitiveness by means of the median-split technique. Two-way analyses of variance revealed significant group by time-to-competition interactions for both cognitive and somatic anxiety. In the case of cognitive anxiety, the high competitive group exhibited no change across time; the low competitive group showed a progressive increase as the competition neared. Findings for somatic anxiety revealed that the low competitive group reported an earlier elevation in the somatic response. Significant main effects of both time-to-event and group (but no interaction) were found for self-confidence. The findings revealed that the high competitive group, although reporting higher levels of self-confidence throughout the experimental period, reported reduced self-confidence on the day of competition; in the low competitive group, self-confidence remained stable. These results suggest that the precompetition temporal patterning of the multidimensional anxiety subcomponents differ as a function of competitiveness.
