Electrospun PCL Scaffolds as Drug Carrier for Corneal Wound Dressing Using Layer-by-Layer Coating of Hyaluronic Acid and Heparin

Due to its ability to reduce scarring and inflammation, human amniotic membrane is a widely used graft for wound dressings after corneal surgery. To overcome donor dependency and biological variances in the donor tissue, artificial nanofibrous grafts acting as drug carrier systems are promising substitutes. Electrospun nanofibrous scaffolds seem to be an appropriate approach as they offer the properties of permeable scaffolds with a high specific surface, the latter one depending on the fiber diameter. Electrospun scaffolds with fiber diameter of 35 nm, 113 nm, 167 nm and 549 nm were manufactured and coated by the layer-by-layer (LbL) technology with either hyaluronic acid or heparin for enhanced regeneration of corneal tissue after surgery. Studies on drug loading capacity and release kinetics defined a lower limit for nanofibrous scaffolds for effective drug loading. Additionally, scaffold characteristics and resulting mechanical properties from the application-oriented characterization of suture pullout from suture retention tests were examined. Finally, scaffolds consisting of nanofibers with a mean fiber diameter of 113 nm were identified as the best-performing scaffolds, concerning drug loading efficiency and resistance against suture pullout.
Habitat and climate shape growth patterns in a mountain ungulate

Abstract Uptake and use of energy are of key importance for animals living in temperate environments that undergo strong seasonal changes in forage quality and quantity. In ungulates, energy intake strongly affects body mass gain, an important component of individual fitness. Energy allocation among life‐history traits can be affected by internal and external factors. Here, we investigate large‐scale variation in body growth patterns of Alpine chamois Rupicapra rupicapra rupicapra, in relation to sex, age, temperature, and habitat variations across 31 (sub)populations in the Central European Alps. Taking advantage of an exceptionally large dataset (n = 178,175) of chamois hunted over 27 consecutive years between 1993 and 2019 in mountain ranges with different proportions of forest cover, we found that (i) patterns of body mass growth differ between mountain ranges, with lower body mass but faster mass growth with increasing proportion of forest cover and that (ii) the effect of spring and summer temperatures on changes in body growth patterns are larger in mountain ranges with lower forest cover compared to mountain ranges with higher forest cover. Our results show that patterns of body mass growth within a species are more plastic than expected and depend on environmental and climatic conditions. The recent decline in body mass observed in Alpine chamois populations may have greater impacts on populations living above the treeline than in forests, which may buffer against the effects of increasing temperatures on life‐history traits.
Extraction of diffusion state transitions in single-particle tracking data of membrane receptors

Single-particle tracking reports on the mobility of biomolecules in living cells with high spatial and temporal resolution. From single-particle trajectories, information such as the diffusion coefficient and diffusion state can be derived. Changes in particle dynamics within single trajectories can be extracted by segmentation, which provides information on transitions between different functional states of a biomolecule. However, such analyses of single-particle tracking data is complex and time-consuming. Here, we present a pipeline that enables a straightforward and rapid analysis of single-particle tracking data. It incorporates mean-squared displacement analysis of trajectories that distinguishes between immobile, confined, and free diffusion states, as well as the analysis of diffusion state transitions within a trajectory with transition counts and hidden Markov modeling. We apply this analysis to single-molecule trajectories of un-activated Fab-bound and internalin B-bound MET receptors in the plasma membrane of live HeLa cells. We found that ligand activated receptors move slower and more confined and exhibit more transitions from free to confined diffusion states than un-activated receptors. This suggests that the confined diffusion state functions as an intermediate between free and immobile, as this state is most likely changing the diffusion type in the following segment. Hidden Markov modeling reported three diffusion states with increased transition probabilities towards the less mobile and immobile states upon ligand activation. The less mobile state operates as an intermediate state, as it has the highest transition probabilities. The analysis pipeline can be readily applied to single-particle tracking data of other membrane proteins and provides rapid access to information that can be associated with functional states.

Multicolor stimulated Raman scattering microscopy and its applications

Stimulated Raman scattering (SRS) microscopy allows for sensitive molecular vibrational imaging and is opening up a variety of biomedical applications. To fully utilize the capability of SRS, we developed a multicolor SRS microscope, which is capable of acquiring SRS images at the video rate, while the wavenumber can be changed in a frame-by-frame manner. Also our system is integrated with a confocal fluorescence microscope. I will introduce various vibrational imaging applications such as label-free imaging, supermultiplex imaging, metabolic imaging, and so on. We also describe functional Raman probes, which will further broaden the applications of SRS microscopy.
Analysis of full-body motion capture system design based on ultra wide band technology

UWB signals are widely used in indoor precise positioning due to their good temporal resolution. Motion capture can be realized by tracking human joints in 3d space with the precise positioning characteristics of the UWB system. Compared to traditional motion capture technology, UWB technology has advantages in cost and system complexity. This paper reviews existing research of the motion capture based on UWB technology, and analyzes the design of the whole body motion capture system based on UWB technology from three aspects of the algorithm, application scenarios and technical difficulties. The research proves that UWB technology can be used as a substitute for the existing motion capture technology and has certain competitiveness. However, the research on motion capture system based entirely on UWB technology is still limited to studying individual limbs of human body. Therefore, the large-scale application of UWB system for motion capture under complex indoor conditions still needs further research.
Innovative Business Strategies in the Face of COVID-19: An Approach to Open Innovation of SMEs in the Sonora Region of Mexico

The purpose of this study is to analyze and verify the effects of the business strategy (financial and market) and innovation management exerted on the economic indicators and business performances of SMEs in the south-central region of Sonora in Mexico. The effect of electronic commerce and the home office in the management of innovation and corporate performance is also analyzed. In addition, a multigroup analysis was carried out to check if there are significant differences between family and non-family businesses. The sample analyzed comprises 498 SMEs with between 6 and 250 employees in the commerce sector. To collect the information, a questionnaire was developed and applied to the online SME manager through the LimeSurvey Professional platform. The field work was carried out from February to October 2021. PLS-SEM was used for the data analysis. The results report that the business strategy (financial and market) does not have significant effects on the management of innovation and on the economic indicators of SMEs. On the other hand, innovation management has positive and significant effects on the economic indicators and business performance of SMEs. It is also revealed that economic indicators have a positive and significant effect on business performance. Open innovation strategies such as electronic commerce have positive and significant effects on innovation management and corporate performance. Similarly, the home office has significant effects on innovation management. Finally, unknown SMEs were found to be the best performers in innovation management and business performance. The study contributes to the development of the theory of competitive behavior and the theory of resources and capabilities.
Niche partitioning and intraspecific shared webs in two species of Modisimus Simon, 1893 (Pholcidae: Araneae)

Abstract. The pholcid spiders Modisimus bribri Huber, 1998 and M. guatuso Huber, 1998 construct three-dimensional webs, including sheet dome and irregular shapes, occasionally shared by males and females. We studied species spatial disaggregation and confirmed web-sharing and prey capture dominance in shared webs. We observed 22 M. bribri and 25 M. guatuso webs and recorded their height above the ground, dome dimensions, and web-sharing. In shared webs, we recorded which individual captured prey. Modisimus bribri builds webs at greater heights (∼6.5 times), with larger dimensions (∼2 times) than M. guatuso. In both species, neither the occupant sex nor the number of individuals on the web had a significant effect on web dimensions. We confirmed differential web location between species and did not find evidence of chivalrous dominance in prey-capture in shared webs. This study contributes to the general knowledge of three-dimensional web-building spiders, posing new questions for future research.
Numerical Evaluation of Embedded Smart Irrigation System for Deep-Rooted Desert Trees

Kingdom of Saudi Arabia's green initiative program aims to plant ten million trees across the country. The kingdom mostly has a desert climate with constrained water resources. The sand dunes and sheets spread across hundreds of square kilometers in the country. The plantation of trees and saplings in these harsh conditions cannot be achieved without an efficient irrigation system. Native desert trees have deep roots and smart irrigation techniques can be intrinsically applied to irrigate these plants, even in the wild. In this study, a smart irrigation system for deep-rooted trees has been numerically assessed for the sandy desert conditions. The partially saturated, subsurface flow analysis has been done by using FEM modeling. The study results exhibit the possible placement of smart irrigation diffusers along with the depth. The method can be used to irrigate only the target root zone and oblige in water conservation. The field installation of a smart irrigation system in deep strata and its long-term maintenance will be some of the prospective challenges for field engineers.
Effect of incorporation of snail meat powder on sensory attributes and consumer acceptability of sorghum‐wheat buns

Abstract Formulation of foods from –low‐lysine cereals fortified with animal protein is a potentially sustainable approach to enhance protein quality in diet due to nutritional compensation while buns are valuable vehicles to deliver nutrients to human body because of their relatively noble eating quality and extended shelf life. The aim of this study was to evaluate the sensory attributes and consumer acceptability of sorghum‐wheat buns containing snail meat powder (SMP). Buns were prepared by replacing 5, 10, 15, 20, and 25% of sorghum‐wheat composite flour with SMP. Principal component analysis (PCA) revealed 99% total variation of 23 attributes for buns scored by a descriptive sensory panel, of which 98% was due to the proportion of SMP that replaced sorghum‐wheat composite flour in buns and the remainder 1% was due to the buns’ physical appearance. Compositing sorghum‐wheat buns with SMP imparted positive consumer attributes of fine crumb, sponginess, and crumby texture. It also resulted in buns with reasonably high sensory acceptability as evaluated by 8‐ to 9‐year‐old school children. The buns can serve as supplementary rich sources of protein for alleviating the menace of protein energy malnutrition in sub‐Saharan Africa.
Indoor Localization Using Mind Evolutionary Algorithm-Based Geomagnetic Positioning and Smartphone IMU Sensors

With the pervasiveness and ubiquitous distribution of the magnetic field in indoor environments, indoor localization using magnetic positioning (MP) has attracted considerable attention. This work concentrates on the MP and pedestrian dead reckoning (PDR) method, and constructs a fusion system for smartphones using MP and PDR based on the extended Kalman filter (EKF). The mind evolutionary algorithm (MEA) is introduced to search for the optimal magnetic position based on a heuristic searching strategy, which uses the similartaxis and dissimilation for the evolutionary operation. In the PDR module, the acceleration characteristics of different walking patterns are analyzed and the corresponding features are extracted. The enhanced genetic algorithm-based extreme learning machine (EGA-ELM) is adopted to train these features and address the gait recognition problem of different walking patterns. Finally, to obtain a lightweight and high-precision fusion method, MEA-based MP is integrated with PDR based on the EKF. Extensive experiments are conducted to evaluate the proposed methods. The testing results showed that MEA-based MP can obtain a location error within 2.3 m and steps can be recognized with a mean accuracy of 95% when different users participate in testing. The positioning results after fusion with PDR reveal that the mean location error and root-mean-square error (RMSE) are 1.25 m and 1.53 m respectively, which outperforms the MP, PDR, MP and PDR fusion methods using improved particle filter (IPF) and genetic particle filter (GPF).
Hyperspectral unmixing using weighted sparse regression with total variation regularization

ABSTRACT Spectral unmixing aims at identifying the pure spectral signatures in hyperspectral images and simultaneously estimating their proportions in each pixel of the scene. By using an available spectral library as a dictionary, sparse-regression-based approaches aim at finding a subset of the dictionary that can optimally model each pixel in a given hyperspectral image. regularizer has been widely considered as a regularization strategy to exploit the sparsity of the unmixing solution. Further sparsity can be imposed by also using weighting factors. However, most existing strategies focus on the unmixing solution ignoring the gradient information. To account for the gradient information in hyperspectral unmixing, we propose a weighted sparse regression with total variation (WSRTV) unmixing model. The proposed WSRTV model incorporates gradient information in the sparse regression formulation by means of the weighted total variation (WTV) regularizer. The model imposes sparsity on both the solution and the gradient to improve the performance of unmixing. A dual symmetric Gauss-Seidel alternating direction method of multipliers (sGSADMM) is designed to optimize the proposed model. The designed algorithm both handles the anisotropic and isotropic WTV. Simulated and real hyperspectral data demonstrate the effectiveness of the proposed framework.
Analysis of peripheral blood parameters for the diagnosis of inflammatory activity in rheumatoid arthritis

Currently, it is considered generally accepted to assess the activity of inflammation in rheumatoid arthritis (RA) according to the disease activity index (DAS28), which requires computer technology. However, there have been reports that inflammatory activity in autoimmune diseases can be diagnosed with peripheral blood counts.Aim. To clarify the possibility of using peripheral blood parameters for the diagnosis of inflammatory activity in rheumatoid arthritis.Material and methods. The study included 100 patients with RA who were consecutively hospitalized in the first quarter of 2021 due to an exacerbation. The control group consisted of 59 healthy donors. When patients were admitted to the clinic, along with standard clinical, laboratory and radiological parameters, the neutrophil-tolymphocyte (NLR) and platelet-to-lymphocyte (PLR) ratios were determined.Results. Correlation analysis of the studied clinical and laboratory parameters of the inflammatory activity of RA patients using the Pearson method showed that the NLR indicator, in contrast to the PLR, was statistically significant (p<0.05) correlated with the swollen joint count (r=0.236), the values of C-reactive protein (CRP) (r=0.448), erythrocyte sedimentation rate (ESR) (r=0.274) and DAS28-ESR (r=0.274). ROC-analysis of the sensitivity and specificity of the NLR value in relation to the CRP and ESR indicators confirmed an acceptable level of sensitivity and specificity in assessing the inflammatory activity of RA.Conclusions. The NLR index, calculated from the data of the analysis of peripheral blood, can be used in clinical practice as an objective and accessible marker of the inflammatory activity of RA.
The Date of Appearance of Philistine Pottery at Megiddo: A Computational Approach

This paper addresses the question of the date of appearance of Philistine Bichrome pottery at Megiddo through a new computational approach, using recently developed chronology software. Based on historical dates, we obtain a terminus post quem of 1183 b.c.e. for the start of Philistine Bichrome at Megiddo using a broad model, and a terminus post quem of 1124 b.c.e. under stronger chronological hypotheses. Adding radiocarbon results at 68.2% confidence level to the model yields a narrow range of 1111–1086 b.c.e. for the appearance of Bichrome (1128—1079 b.c.e. for 95.4%). The paper also presents results suggesting that Stratum VIIB ended during, or only slightly before, the reign of Ramesses III (1184–1153 b.c.e.).

Modeling and Design of Passive Planar Components for EMI Filters

The magnetic components with planar technology join in the current trends in Power Electronics (PE), namely increasing the switching frequency of PE structures and reducing the size of the power converters. The first tendency imposes strong constraints in terms of electromagnetic compatibility of equipments. The latter has to be considered by engineers at the beginning of the design of Power converters on the basis of reliable models, which are not sufficiently developed for planar components in scientific literature.This PhD work thereby focuses on the modeling of planar components for the applications of EMI filters. Different methods are developed during this study in order to accurately evaluate the parasitic elements of planar common-mode chokes: parasitic capacitances and leakage inductances. A part of this dissertation concerns the equivalent circuit modeling of the frequency behavior of CM chokes. An automated approach, based on a fitting algorithm developed for elaborating reliable and robust equivalent circuits. Analytical approaches (Electric Field Decomposition) and semi-analytical (Green’s Function) are proposed as well for calculating the values of these parasitic elements. The last part of this dissertation is oriented to conception, with the realization of two structures of innovative components, the first one based on a parasitic capacitance cancellation technique using structural parasitic elements and the second one on the association of two magnetic cores with different materials and geometries
