Applications of gaseous chlorine dioxide on postharvest handling and storage of fruits and vegetables A review
Year: 2019

Foodborne illness and decay loss caused by microorganisms are primary concerns for processors and marketers of fruits and vegetables. Interest in using gaseous chlorine dioxide (ClO2) treatments for postharvest sanitation has increased in recent years due to its many advantages over other sanitizers, including its powerful antimicrobial activity, and low environmental impact. It also has low corrosivity to packing equipment at food sanitation concentrations, but can be corrosive in highly concentrated aqueous solutions. Like many water mediated sanitizers, ClO2 has been applied to various commodities. However, gaseous ClO2 has many advantages over its aqueous formulations in addition to being less corrosive, including ease of mixing with air, rapid diffusion, and the ability to penetrate permeable surfaces and biofilms. A combination of aqueous sanitizer washing and application of gaseous ClO2 will enhance decontamination of both foodborne and plant pathogens. This article compares ClO2 with other commonly used sanitizers, discusses the mechanisms of ClO2 against microorganisms, and focuses intensively on the applications of gaseous ClO2, especially controlled release ClO2, on fruits and vegetables to reduce pathogen infection and maintain food safety and quality of fresh produce.

Robust and optimal sparse regression for nonlinear PDE models.
Venue: Chaos
Year: 2019

This paper investigates how models of spatiotemporal dynamics in the form of nonlinear partial differential equations can be identified directly from noisy data using a combination of sparse regression and weak formulation. Using the 4th order Kuramoto Sivashinsky equation for illustration, we show how this approach can be optimized in the limits of low and high noise, achieving accuracy that is orders of magnitude better than what existing techniques allow. In particular, we derive the scaling relation between the accuracy of the model, the parameters of the weak formulation, and the properties of the data, such as its spatial and temporal resolution and the level of noise.
Differential Reflecting Modulation for Reconfigurable Intelligent Surface Based Communications
Venue: IEEE Communications Letters
Year: 2021

Reconfigurable intelligent surface (RIS) based communications have emerged as a new paradigm. This letter proposes a differential reflecting modulation (DRM) scheme for RIS based communication systems. In DRM, information bits are jointly carried by the activation permutations of the reflecting patterns and the phases of the transmitted signals, leading to that DRM can work without any channel state information (CSI) at the transmitter, RIS or receiver. In other words, DRM can release the intricate and resource consuming channel estimation in the transmission process. Simulation results show that the proposed DRM pays an acceptable SNR penalty compared to non differential modulation with coherent detection.
Mixed phytochemicals mediated synthesis of copper nanoparticles for anticancer and larvicidal applications
Venue: Heliyon
Year: 2021

The synthesis of copper nanoparticles (CuNPs) using Wrightia tinctoria (Wt) R.Br extract is defined in this article as being convenient, environmentally friendly, and non toxic. UV visible spectrophotometry, FT IR, XRD, particle size analyser, SEM EDAX and TEM methods were used to describe the physicochemical properties of Wt extract mediated synthesized CuNPs (Wt CuNPs) The Wt CuNPs synthesized was found to be monodispersed and spherical, with an average size of 15 nm. Gas chromatography and mass spectrometry (GC MS) research revealed that the Wt R.Br plant extract contains various phytochemical compounds. The properties of Wt CuNPs were verified by the findings of characterization tests. Via in silico molecular docking experiments with established targets, the underlying mechanisms of cytotoxicity against breast cancer and larvicidal behaviour against Aedes aegypti of Wt CuNPs were investigated. Interestingly, in vitro cytotoxicity studies showed 50% cell death (IC50) of Wt CuNPs treated MCF 7 cells and Vero Cells (Kidney epithelial cells) were displayed at 119.23 mg.mL 1 and 898.75 mg.mL 1, respectively. Also, Wt CuNPs showed least LC50 and LC90 values for larvicidal activity against A. aegypti were of 32.10 mg.mL 1 and 21.70 mg.mL 1, respectively. Furthermore, Wt CuNPs is found to be less toxic and biocompatible in haemolytic assays. The findings clearly showed that biosynthesized Wt CuNPs have been used as a possible anticancer and larvicidal agent, as well as being environmentally friendly.

Optical aberrations in the mouse eye
Venue: Vision Research
Year: 2006

The mouse eye is a widely used model for retinal disease and has potential to become a model for myopia. Studies of retinal disease will benefit from imaging the fundus in vivo. Experimental models of myopia often rely on manipulation of the visual experience. In both cases, knowledge of the optical quality of the eye, and in particular, the retinal image quality degradation imposed by the ocular aberrations is essential. In this study, we measured the ocular aberrations in the wild type mouse.  Twelve eyes from six four week old black C57BL/6 wild type mice were studied. Measurements were done on awake animals, one being also measured under anesthesia for comparative purposes. Ocular aberrations were measured using a custom built Hartmann Shack system (using 680 nm illumination) Wave aberrations are reported up to fourth order Zernike polynomials. Spherical equivalent and astigmatism were obtained from the 2nd order Zernike terms. Modulation Transfer Functions (MTF) were estimated for the best focus, and through focus, to estimate depth of focus. All reported data were for 1.5 mm pupils.  Hartmann Shack refractions were consistently hyperopic (10.12+ 1.41 D, mean and standard deviation) and astigmatism was present in many of the eyes (3.64+ 3.70 D, on average) Spherical aberration was positive in all eyes (0.15+ 0.07 microm) and coma terms RMS were significantly high compared to other Zernike terms (0.10+ 0.03 microm) MTFs estimated from wave aberrations show a modulation of 0.4 at 2c/deg, for best focus (and 0.15 without cancelling the measured defocus) For that spatial frequency, depth of focus estimated from through focus modulation data using the Rayleigh criterion was 6D. Aberrations in the eye of one anesthetized mouse were higher than in the same eye of the awake animal.  Hyperopic refractions in the mouse eye are consistent with previous retinoscopic data. The optics of the mouse eye is far from being diffraction limited at 1.5 mm pupil, with significant amounts of spherical aberration and coma. However, estimates of MTFs from wave aberrations are higher than previously reported using a double pass technique, resulting in smaller depth of field predictions. Despite the large degradation imposed by the aberrations these are lower than the amount of aberrations typically corrected by available correction techniques (i.e. adaptive optics) On the other hand, aberrations do not seem to be the limiting factor in the mouse spatial resolution. While the mouse optics are much more degraded than in other experimental models of myopia, its tolerance to large amounts of defocus does not seem to be determined entirely by the ocular aberrations.
Modelisation des rizieres irriguees et integration dans hydrotel application au bassin versant de la riviere Cau au Vietnam.
Year: 2018

La gestion de l'eau pour l'irrigation des rizieres fait appel a des processus complexes. Le modele Hydrotel est un outil qui permet de simuler les processus hydrologiques a l'echelle des bassins versants. Toutefois, ce modele ne permet pas de prendre en compte le comportement hydrologique particulier des rizieres. La presente etude vise a developper un sous modele qui, integre dans Hydrotel, permettra de prendre en compte le comportement hydrologique des rizieres et leur irrigation. Le modele Hydrotel, avec et sans le sous modele developpe specifiquement pour les rizieres, a ete applique sur la partie amont du bassin versant de la riviere Cau au Vietnam. Cette application a demontre que la prise en compte des rizieres et la simulation de leur fonctionnement hydrologique, avec le sous modele developpe, permettent d'ameliorer la qualite des simulations hydrologiques sur ce bassin versant. Hydrotel ainsi modifie pourra donc etre utilise, notamment, pour etudier l'impact des rizieres sur les ressources en eau de bassins versants ou la superficie des rizieres est importante.
Age invariant face recognition: a survey on facial aging databases, techniques and effect of aging
Venue: Artificial Intelligence Review
Year: 2018

Age invariant face recognition (AIFR) is highly required in many applications like law enforcement, national databases and security. Recognizing faces across aging is difficult even for humans; hence, it presents a unique challenge for computer vision systems. Face recognition under various intra person variations such as expression, pose and occlusion has been an intensively researched field. However, age invariant face recognition still faces many challenges due to age related biological transformations in presence of the other appearance variations. In this paper, we present a comprehensive review of literature on cross age face recognition. Starting with the biological effects of aging, this paper presents a survey of techniques, effects of aging on performance analysis and facial aging databases. The published AIFR techniques are reviewed and categorized into generative, discriminative and deep learning methods on the basis of face representation and learning techniques. Analysis of the effect of aging on the performance of age invariant face recognition system is an important dimension. Hence, such analysis is reviewed and summarized. In addition, important facial aging databases are briefly described in terms of the number of subjects and images per subject along with their age ranges. We finally present discussions on the findings, conclusions and future directions for new researchers.
A comparative study in China and Australia of parental engagement in transition to school
Year: 2018

This is a comparative study conducted in both China and Australia examining parental engagement in transition to school; investigating parents' perceptions and engagement, and influencing factors. A mixed methods approach was applied to collecting and analyzing both quantitative and qualitative data in Beijing, China and Queensland, Australia. The results show that Chinese and Australian parents engaged differently in transition practices. Bronfenbrenner's bioecological theory and PPCT model, was used to frame how Chinese and Australian parents' transition engagement is influenced by Person factors (children's characteristics, parents' role construction, self efficacy, time and energy, and school and transition experiences) and Context factors (kindergarten, school, and teacher influence, social influence, policy influence, and societal and cultural influence) This study further contributes to the international education context by comparing parental engagement under globalization.
Follistatin like 1 in development and human diseases
Venue: Cellular and Molecular Life Sciences
Year: 2018

Follistatin like 1 (FSTL1) is a secreted glycoprotein displaying expression changes during development and disease, among which cardiovascular disease, cancer, and arthritis. The cardioprotective role of FSTL1 has been intensively studied over the last years, though its mechanism of action remains elusive. FSTL1 is involved in multiple signaling pathways and biological processes, including vascularization and regulation of the immune response, a feature that complicates its study. Binding to the DIP2A, TLR4 and BMP receptors have been shown, but other molecular partners probably exist. During cancer progression and rheumatoid arthritis, controversial data have been reported with respect to the proliferative, apoptotic, migratory, and inflammatory effects of FSTL1. This controversy might reside in the extensive post transcriptional regulation of FSTL1. The FSTL1 primary transcript also encodes for a microRNA (miR 198) in primates and multiple microRNA binding sites are present in the 3'UTR. The switch between expression of the FSTL1 protein and miR 198 is an important regulator of tumour metastasis and wound healing. The glycosylation state of FSTL1 is a determinant of biological activity, in cardiomyocytes the glycosylated form promoting proliferation and the non glycosylated working anti apoptotic. Moreover, the glycosylation state shows differences between species and tissues which might underlie the differences observed in in vitro studies. Finally, regulation at the level of protein secretion has been described.
Management of Neonates Born to Mothers With Graves' Disease
Venue: Pediatrics
Year: 2016

Neonates born to mothers with Graves' disease are at risk for significant morbidity and mortality and need to be appropriately identified and managed. Because no consensus guidelines regarding the treatment of these newborns exist, we sought to generate a literature based management algorithm. The suggestions include the following: (1) Base initial risk assessment on maternal thyroid stimulating hormone (TSH) receptor antibodies. If levels are negative, no specific neonatal follow up is necessary; if unavailable or positive, regard the newborn as "at risk" for the development of hyperthyroidism. (2) Determine levels of TSH receptor antibodies in cord blood, or as soon as possible thereafter, so that newborns with negative antibodies can be discharged from follow up. (3) Measurement of cord TSH and fT4 levels is not indicated. (4) Perform fT4 and TSH levels at day 3 to 5 of life, repeat at day 10 to 14 of life and follow clinically until 2 to 3 months of life. (5) Use the same testing schedule in neonates born to mothers with treated or untreated Graves' disease. (6) When warranted, use methimazole (MMI) as the treatment of choice; b blockers can be added for sympathetic hyperactivity. In refractory cases, potassium iodide may be used in conjunction with MMI. The need for treatment of asymptomatic infants with biochemical hyperthyroidism is uncertain. (7) Assess the MMI treated newborn on a weekly basis until stable, then every 1 to 2 weeks, with a decrease of MMI (and other medications) as tolerated. MMI treatment duration is most commonly 1 to 2 months.
Hybrid finite time trajectory tracking control of a quadrotor.
Venue: ISA transactions
Year: 2019

In this paper, accurate trajectory tracking control problem of a quadrotor with unknown dynamics and disturbances is addressed by devising a hybrid finite time control (HFTC) approach. An adaptive integral sliding mode (AISM) control law is proposed for altitude subsystem of the quadrotor, whereby underactuated characteristics can decoupled. Backstepping technique is further deployed to control the horizontal position subsystem. To exactly attenuate external disturbances, a finite time disturbance observer (FDO) combining with nonsingular terminal sliding mode (NTSM) control strategy is constructed for attitude subsystem, and thereby achieve finite time stability. Using the compounded control scheme, trajectory tracking errors can be stabilized rapidly. Simulation results and comprehensive comparisons show that the proposed HFTC scheme has remarkably superior performance.
On fine grained geolocalisation of tweets and real time traffic incident detection
Venue: Inf. Process. Manag.
Year: 2019

Recently, geolocalisation of tweets has become important for a wide range of real time applications, including real time event detection, topic detection or disaster and emergency analysis. However, the number of relevant geotagged tweets available to enable such tasks remains insufficient. To overcome this limitation, predicting the location of non geotagged tweets, while challenging, can increase the sample of geotagged data and has consequences for a wide range of applications. In this paper, we propose a location inference method that utilises a ranking approach combined with a majority voting of tweets, where each vote is weighted based on evidence gathered from the ranking. Using geotagged tweets from two cities, Chicago and New York (USA) our experimental results demonstrate that our method (statistically) significantly outperforms state of the art baselines in terms of accuracy and error distance, in both cities, with the cost of decreased coverage. Finally, we investigated the applicability of our method in a real time scenario by means of a traffic incident detection task. Our analysis shows that our fine grained geolocalisation method can overcome the limitations of geotagged tweets and precisely map incident related tweets at the real location of the incident.
The Chapter Heading Characteristics and Translation Skills of Chapter Fictions in Ming and Qing Dynasties
Year: 2019

The chapter heading for chapter fictions in Ming and Qing Dynasties is an important part of the novel and has distinct characteristics. The main manifestations are as follows: First, the language is concise and clear. Second, the syntactic structure is fixed. Third, it covers the elements of people, things, and verbs. In the process of translating the chapter fictions in Ming and Qing dynasties, translators need to master the characteristics of the chapter fictions in Ming and Qing dynasties, effectively and skillfully use parts of speech conversion, amplification and omission and attach importance to the translation of adverbs in chapter fictions. The translation of chapter fictions in Ming and Qing Dynasties will be more in line with their own characteristics and more accurate through the mastery and use of these translation techniques.
Characterization of 300 GHz Wireless Channel on a Computer Motherboard
Venue: IEEE Transactions on Antennas and Propagation
Year: 2016

This paper presents characterization of 300 GHz wireless channel on a computer motherboard, where several different measurement scenarios have been considered. Results indicate that the presence of the ground plane and/or vertical parallel plate structures in the channel introduces multipath that, if constructively superimposed, may create a path loss lower than free space propagation path loss. In addition, it has been found that a few centimeters of vertical misalignment between the transmitter and the receiver result in a path loss greater than 5 dB. Furthermore, the results indicate that vertical components such as dual in line memory modules with reflection coefficient close to one for all incident angles can be used to create directed non line of sight (LoS) links with wide coherence bandwidth. Finally, for LoS propagation obstructed by large objects, such as a heatsink, the path loss exponent of 1.77 is found, while the rotating fan causes periodic fading in the received power, indicating that channel equalization techniques will be needed to overcome deep fades. All these results indicate that optimal communications can be achieved by carefully positioning the antennas with respect to the motherboard layout.
Interaction Taxonomy for Tracking of User Actions in Visual Analytics Applications
Venue: Handbook of Human Centric Visualization
Year: 2014

In various application areas (social science, transportation, or medicine) analysts need to gain knowledge from large amounts of data. This analysis is often supported by interactive Visual Analytics tools that combine automatic analysis with interactive visualization. Such a data analysis process is not streamlined, but consists of several steps and feedback loops. In order to be able to optimize the process, identify problems, or common problem solving strategies, recording and reproducibility of this process is needed. This is facilitated by tracking of user actions categorized according to a taxonomy of interactions.Visual Analytics includes several means of interaction that are differentiated according to three fields: information visualization, reasoning, and data processing. At present, however, only separate taxonomies for interaction techniques exist in these three fields. Each taxonomy covers only a part of the actions undertaken in Visual Analytics. Moreover, as they use different foundations (user intentions vs. user actions) and employ different terminology, it is not clear to what extent they overlap and cover the whole Visual Analytics interaction space. We therefore first compare them and then elaborate a new integrated taxonomy in the context of Visual Analytics.In order to show the usability of the new taxonomy, we specify it on visual graph analysis and apply it to the tracking of user interactions in this area.
