An assessment of the relative impact of hidradenitis suppurativa, psoriasis, and obesity on quality of life
Venue: International journal of women's dermatology
Year: 2018

Hidradenitis suppurativa (HS) and psoriasis are inflammatory skin diseases associated with obesity. Each disease is likely to impact the quality of life of patients, but the relative impact of each disease is unknown.  This study aimed to determine whether skin disease or obesity is more distressing to obese patients who have either psoriasis or HS.  A cohort of obese patients with psoriasis and HS was surveyed using a time trade off utility. T tests and regression analysis were used to compare differences in impact on quality of life between skin disease and obesity for patients with HS and psoriasis. Further analyses were adjusted for degree of obesity and severity of disease.  A total of 79 subjects completed the survey. Obese patients with HS were heavier than patients with psoriasis (mean body mass index 38.1 kg/m2 vs. 34.9 kg/m2) Obese patients with either HS or psoriasis were both willing to trade a significantly higher proportion of their life to live without skin disease than to live at a normal weight (p .01) This effect persisted after controlling for disease severity and weight. Patients with HS were willing to trade significantly more years of life to live at a normal weight than obese patients with psoriasis (14 vs. 7; p .04) Limitations This was a small study conducted at an academic institution.  In this study population, obesity was more severe in patients with HS than in those with psoriasis. Even after controlling for relative severity, HS was more problematic for subjects in this study than weight when these conditions existed concomitantly.
A New Design of Codebook for Hybrid Precoding in Millimeter Wave Massive MIMO Systems
Venue: Symmetry
Year: 2021

The precoding scheme based on codebooks is used to save the same set of codebook in advance at the transmitter and the receiver, then, the receiver selects the most appropriate precoding matrix from codebooks according to different channel state information (CSI) Therefore, the design of codebook plays an important role in the performance of the whole scheme. The symmetry based hybrid precoder and combiner is a highly energy efficient structure in the millimeter wave massive multiple input multiple output (MIMO) system, but at the same time, it also has the problems of high bit error rate and low spectral efficiency. In order to improve the spectral efficiency, we formulate the codebook design as a joint optimization problem and propose an iteration algorithm to obtain the enhanced codebook by combining the compressive sampling matching pursuit (CoSaMP) algorithm with the dictionary learning algorithm. In order to prove the validity of the proposed algorithm, we simulate and analyze the change of the spectral efficiency of the algorithm with the signal to noise ratio (SNR) and the number of radio frequency (RF) chains of different precoding schemes. The simulation results demonstrate that the spectral efficiency of the algorithm is obviously outstanding compared with that of the OMP based joint codebook algorithm and the hybrid precoding algorithm with quantization algorithm under low SNR and different numbers of RF chains. Particularly, when SNR is lower than 0 dB, the proposed algorithm performs very close to the optimal unconstrained precoding algorithm.
Manual and automated intima media thickness and diameter measurements of the common carotid artery in patients with renal failure disease
Venue: Comput. Biol. Medicine
Year: 2014

The objective of this study was to investigate differences in intima media thickness (IMT) and diameter (D) measurements of the common carotid artery (CCA) in ultrasound imaging in normal subjects and renal failure disease (RFD) patients. Manual measurements by two experts and automated segmentation measurements (based on snakes and active contour models (ACM) were carried out on 73 normal subjects, and 80 RFD patients. Statistical analysis was carried out using the Wilcoxon rank sum test at p<0.05. Results demonstrated that the mean IMT and D measurements were significantly higher for the RFD group versus the normal group. Moreover, there was no significant difference between the manual and automated measurements. The ACM segmentation was slightly more accurate than segmentation based on snakes. Further work is needed to validate these findings on a larger group of subjects.
Melt electrowriting with novel milk protein/PCL biomaterials for skin regeneration.
Venue: Biomedical materials
Year: 2019

Demand for skin replacements is rapidly increasing as burn and full thickness wounds are difficult to repair due to the low regeneration capability of innate tissues, as well as the physical drawbacks associated with currently available substitutes. To address this need, an emerging 3D printing technique, melt electrowriting (MEW) was used to create novel bioactive scaffolds to promote skin regeneration. Polycaprolactone (PCL) a bioresorbable and biocompatible, synthetic polymer with Food and Drug Administration approval for use in the human body was selected as scaffold material due to its mechanical stability, flexibility, and superior melt processing properties. In order to increase PCL's biological functionality bioactive milk proteins (MPs) were blended with PCL. To date, this is the first study of its kind detailing the tissue regenerative capacity of PCL containing MPs as bioactive additives for skin regeneration using MEW. The aim of this study was to MEW MP/PCL tissue engineered constructs (TEC) and assess their suitability for generating tissue in vitro. The MPs, lactoferrin (LF) and whey protein (WP) were mixed with PCL individually at varying concentrations (0.05% 0.1% 0.25% and in combination (COMB) at concentrations of 0.25% each. TECs were characterized chemically, physically, and their biological activity assessed in vitro. Physical characterisation of MEW MP/PCL scaffolds showed that reproducible, layered micron range scaffolds could be fabricated; displaying high porosity, low degradation, and rapid protein release. Biological activity, determined via an in vitro skin model using human keratinocytes (HaCaTs) and normal human dermal fibroblasts (Nhdf) cells, showed significantly increased cell growth, spreading, and infiltration into LF (0.25% containing scaffolds and COMB scaffolds when compared to PCL alone (p<=0.05) These findings demonstrated that the combined addition of LF and WP increased the biological activity of MEW PCL scaffolds and could be potentially used as a TEC for deep tissue dermal regeneration.
Feline Autoimmune Skin Diseases Pathogenesis to Therapy 23 rd ECVIM CA Congress 2013
Year: 2016

Because of the rarity of most of the immune mediated, and particularly, autoimmune skin diseases (AISD) in cats, such diseases represent a diagnostic and therapeutic challenge for general as well as specialty veterinarians. A correct diagnosis and understanding of the immunopathomechanism(s) of each of these specific diseases are often the key factors involved in making a rational choice among the available drugs.
Linear Queries Estimation with Local Differential Privacy
Venue: AISTATS
Year: 2019

We study the problem of estimating a set of $d$ linear queries with respect to some unknown distribution \mathbf{p} over a domain \mathcal{J}[J] based on a sensitive data set of $n$ individuals under the constraint of local differential privacy. This problem subsumes a wide range of estimation tasks, e.g. distribution estimation and $d$ dimensional mean estimation. We provide new algorithms for both the offline (non adaptive) and adaptive versions of this problem. In the offline setting, the set of queries are fixed before the algorithm starts. In the regime where $n\lesssim d^2/\log(J) our algorithms attain $L_2$ estimation error that is independent of $d$ and is tight up to a factor of \tilde{O}\left(\log^{1/4}(J)\right) For the special case of distribution estimation, we show that projecting the output estimate of an algorithm due to [Acharya et al. 2018] on the probability simplex yields an $L_2$ error that depends only sub logarithmically on $J$ in the regime where $n\lesssim J^2/\log(J) These results show the possibility of accurate estimation of linear queries in the high dimensional settings under the $L_2$ error criterion. In the adaptive setting, the queries are generated over $d$ rounds; one query at a time. In each round, a query can be chosen adaptively based on all the history of previous queries and answers. We give an algorithm for this problem with optimal $L_{\infty} estimation error (worst error in the estimated values for the queries w.r.t. the data distribution) Our bound matches a lower bound on the $L_{\infty} error for the offline version of this problem [Duchi et al. 2013]
The enhanced rich H2 from co gasification of torrefied biomass and low rank coal: The comparison of dry/wet torrefaction, synergetic effect and prediction
Year: 2020

In this study, the enhanced rich H2 gas was produced via the co gasification of torrefied biomass and low rank coal in the fixed bed reactor. The properties of wet/dry torrefied char was compared, and then the synergetic effect between dry/wet torrefied char and the low rank coal during the gasification were analyzed to study the enhancing effect of torrefaction on the H2 yield. Moreover, the co pyrolysis reactivity and kinetic analysis were investigated to further determine the synergetic mechanism. The results showed that the change of fundamental compositions in biomass after torrefaction, especially, the removal of cellulose played an important role in the enhancement of H2. Thus, dry torrefaction was more beneficial for improving H2 yield than the wet one. Besides, an obviously synergetic effect was observed from coal and dry torrefied biomass in their ratio 1:1 and 3:1, which was mainly due to the catalytic role of alkali and alkaline earth metallic species, and the transfer of active OH and H radicals from the torrefied biomass to the coal. The co pyrolysis reactivity and kinetic analysis further proved the synergetic effect on reducing activation energy.
Der Weg nach Rio in Brazil: Histoire Croisee, Public Diplomacy and Film Historical Research
Year: 2020

The article discusses the relevance of the histoire croisee approach that has been only marginally applied to film and cinema historical research. Histoire croisee is an approach to write history from a transnational perspective. It tries to overcome the conceptual shortcomings of comparative and transfer studies and integrates them into its theoretical framework. The case study of a political cultural conflict between Brazil and Germany illustrates some of the methodological advantages of the histoire croisee approach. The paper argues that writing historiography from a transnational perspective opens not only new areas of film historical research, it also offers a better understanding of film historical events that otherwise might be overlooked by comparative or transfer studies.
Effects among product attributes, involvement, word of mouth, and purchase intention in online shopping
Year: 2017

With the development of the internet, customers are able to purchase medical equipment not only at the pharmacy but through the internet; notwithstanding, the studies for analyzing the effects of purchasing intention on acquiring medical equipment are deficient. The purpose of the study aims to investigate the effects among product attributes, product involvement, word of mouth, and purchase intention toward online shopping of medical equipment within both of the markets in Taiwan and Mainland China. The present study utilized content validity testing, one way analysis of variance, independent sample t test, and regression analysis to analyze the statistics. The findings demonstrate that all of the factors had positive benefits to customers' purchase intent except product quality. Additionally, the results show that word of mouth from the internet do not significantly positively influence purchase intention owing to the excessive commercialization nowadays. The recommendation will be given for the small and medium enterprises to expand the online business.

Year: 2020

Disaster management is one area in the field that comes with a heavy burden of administrative functions and compliances. Thus, it is vital to consider among managers to put the best man in the field. The purpose of this study is to find out the disaster management program compliance of participants in two provinces in Central Luzon, Philippines. At the same time, identify the problems encountered during the implementation of the programs. This study used a descriptive design with the survey as a primary instrument in data gathering. 110 participants took part in the survey which came from the two selected provinces. The researcher created a questionnaire for the study which underwent validity and reliability test. This study analyzed the gathered data using SPSS 20 and employed the following statistical tools: frequency, percentage, rank, means, t test, ANOVA, and Pearson r. The study found that the respondents "moderately complied" with disaster prevention and mitigation programs and disaster preparedness programs. On the other hand, respondents "complied" with the disaster response programs and disaster recovery and rehabilitation programs. There were no statistical differences in the responses of respondents with different disaster management programs. However, there is a significant relationship between the number of family members and disaster response programs. Based on the results of the study, the researcher recommended pertinent suggestions for the community, policy makers, and local government units.
Additive manufacturing using WAAM with AA5183 wire
Year: 2018

The present study addresses wire arc additive manufacturing of AA5183 aluminium alloy using conventional gas metal arc welding deposition on 20 mm thick AA6082 T6 plate as support material. Microscopic examination demonstrates that the process is feasible, but can be further optimized to reduce gas porosity and hot cracking. Hardness measurements confirmed relative high hardness, i.e. around 75 kg/mm2 in the horizontal plane, and between 70 and 75 kg/mm2 in the vertical plane down to the AA6082 support plate with 100 kg/mm2. Mechanical testing resulted in yield and tensile strength of 145 and 293 MPa, respectively, with lowest value in the through thickness (Z) direction. The ductility was high for orientations parallel (X) with and perpendicular (Y) to the layer deposition direction.
Design, implementation, and thermal modeling of embedded reconfigurable magnetorquer system for nanosatellites
Venue: IEEE Transactions on Aerospace and Electronic Systems
Year: 2015

A reconfigurable magnetorquer coil has been designed and implemented for the CubeSat power management, attitude determination, and control tile (CubePMT) module of CubeSat standard nanosatellites. Magnetorquer coil is a good choice for attitude control and stabilization of nanosatellites. The goal of this work is to provide CubeSat with a magnetorquer coil, which has small dimensions, low weight, and low heat dissipation. The designed magnetorquer coil is reconfigurable and integrated within the printed circuit board internal layers, occupying no extra space on CubeSat. Coils in each layer are treated separately and can be attached and detached through straps. Changing the arrangement of these straps, one can use 1, 2, 3, or 4 coils in series, parallel, or any hybrid combination. This reconfigurable design provides an option for generating different amounts of magnetic moment and resultant torque to stabilize and rotate the satellite. Emissivity of the CubePMT module was found through lab experiments. Power dissipation and the corresponding temperature increase of the CubePMT module are evaluated by thermal modeling.
Towards a Scalable Semantic Based Distributed Approach for SPARQL Query Evaluation
Venue: SEMANTiCS
Year: 2019

Over the last two decades, the amount of data which has been created, published and managed using Semantic Web standards and especially via Resource Description Framework (RDF) has been increasing. As a result, efficient processing of such big RDF datasets has become challenging. Indeed, these processes require, both efficient storage strategies and query processing engines, to be able to scale in terms of data size. In this study, we propose a scalable approach to evaluate SPARQL queries over distributed RDF datasets using a semantic based partition and is implemented inside the state of the art RDF processing framework: SANSA. An evaluation of the performance of our approach in processing large scale RDF datasets is also presented. The preliminary results of the conducted experiments show that our approach can scale horizontally and perform well as compared with the previous Hadoop based system. It is also comparable with the in memory SPARQL query evaluators when there is less shuffling involved.
Photodegradable coumarin derived amphiphilic dendrons for DNA binding: Self assembly and phototriggered disassembly in water and air water interface.
Venue: Colloids and surfaces. B, Biointerfaces
Year: 2019

In this article, we demonstrate the self assembly and photoresponive behavior of a novel coumarin based amphiphilic dendron in both aqueous solution and air water interface. The dendritic structure, namely C IG1, was composed of a lipophilic cholesterol and hydrophilic poly(amido amine) (PAMAM) dendron, and the amphiphilic counterpart is interconnected by a photolabile coumarin carbonate ester, enabling the photoinduced degradation of the amphiphiles in protic solvents via SN1 like mechanism. A Nile red solubilization fluorescence assay suggests a low critical aggregation concentration for the micelle formation of C IG1 in aqueous solutions (3.9 x 10 5 M) the Langmuir analysis further indicates that C IG1 possesses significant compressibility in air water interface, eventually forming homogeneous monolayers with a final molecular area (A0) of 36 A2. Notably, the micelles and Langmuir monolayer are quite stable until photo triggered dissociation based on the photocleavage of C IG1 amphiphile activated by 365 nm incident light. Moreover, the transition in interfacial morphology of the Langmuir monolayer during the assembly and photodegradation processes also can be visually analyzed by incorporating Nile red probes with in situ monitoring through fluorescence microscopy. The thin film deposited on a glass substrate by the Langmuir Blodgett technique also shows a photoresponsive behavior based on the change in the contact angles of a water droplet on the surface upon light stimulation. The binding affinity of C IG1 and cyclic DNA determined by the fluorescence quenching analysis of the coumarin reporter suggests a ground state macromolecular complexation process occurring through polyvalent interactions between the pseudodendrimers and biomacromolecules. The ethidium bromide displacement assay further indicates thus dendriplex formation at low nitrogen to phosphorous value (N/P 1) and confirms that the decomplexation accompanied by DNA release can be achieved through an active phototriggered route under spatiotemporal control.

Impact of Solar Salt aging on corrosion of martensitic and austenitic steel for concentrating solar power plants
Year: 2019

This work addresses the influence of molten nitrate salt chemistry on the corrosion behavior of a martensitic high temperature steel and an austenitic stainless steel. It is one of the first addressing controlled degradation of Solar Salt by controlling the gas atmosphere on top of the melt, thus driving the formation of corrosive ions, mainly oxide ions but also nitrite ions. The stainless steel and high temperature steel samples are subjected to the different operating conditions to demonstrate the variations in corrosivity as a function of gas atmosphere and additionally of artificially added chloride impurities. The results indicate that the atmosphere has a direct impact on the formation of corrosive oxide and nitrite ions. The low Cr steel is found to be more sensitive to chloride impurities, while the stainless steel corrosion is enhanced by the presence of nitrites and oxide ions. All studies are supported by profound molten salt analysis throughout the experiments including the analysis of nitrate, nitrite, oxide and chromate ions as well as cation compositions. Steel samples are analyzed by scanning electron microscopy methods and corrosion rates are extrapolated from 1200 h experiments.
