Static Algorithm Allocation With Duplication in Robotic Network Cloud Systems

Robotic networks can be used to accomplish tasks that exceed the capacity of a single robot. In a robotic network, robots can work together to accomplish a common task. Cloud robotics allows robots to benefit from the massive storage and computing power of the cloud. Previous studies mainly focus on minimizing the cost of resource retrieval by robots by knowing the resource allocation in advance. Duplicating algorithms on multiple nodes can reduce the total time required to execute a task. We address the question of which algorithms should be duplicated and where the duplicates should be placed to improve overall performance. We have developed a procedure to answer wherein a robotic network cloud system should algorithms be executed and whether they should be duplicated to achieve optimal performance in terms of overall task execution time for all robots. Our proposed duplication procedure is optimal in the sense that the number of duplicated algorithms is minimal, while the result provides minimal overall completion time for all robots.
Extracellular Vesicles for Therapeutic Nucleic Acid Delivery: Loading Strategies and Challenges

Extracellular vesicles (EVs) are membrane vesicles released into the extracellular milieu by cells of various origins. They contain different biological cargoes, protecting them from degradation by environmental factors. There is an opinion that EVs have a number of advantages over synthetic carriers, creating new opportunities for drug delivery. In this review, we discuss the ability of EVs to function as carriers for therapeutic nucleic acids (tNAs), challenges associated with the use of such carriers in vivo, and various strategies for tNA loading into EVs.
Output-feedback stabilization control of linear systems with random switchings and state jumps

We are concerned with the stabilization control problem for a class of systems with random switchings and state jumps. We suppose the random switching signal to obey Poisson distribution and intend to use output-feedback control to achieve stabilization. Firstly, based on the statistic property of the distribution of switching points, we derive some sufficient conditions to guarantee the closed-loop system to be almost surely exponentially stable. Then, we pose a parametrization approach to convert the construction conditions of the output-feedback control into a family of matrix inequalities.
Function Investigations and Applications of Membrane Proteins on Artificial Lipid Membranes

Membrane proteins play an important role in key cellular functions, such as signal transduction, apoptosis, and metabolism. Therefore, structural and functional studies of these proteins are essential in fields such as fundamental biology, medical science, pharmacology, biotechnology, and bioengineering. However, observing the precise elemental reactions and structures of membrane proteins is difficult, despite their functioning through interactions with various biomolecules in living cells. To investigate these properties, methodologies have been developed to study the functions of membrane proteins that have been purified from biological cells. In this paper, we introduce various methods for creating liposomes or lipid vesicles, from conventional to recent approaches, as well as techniques for reconstituting membrane proteins into artificial membranes. We also cover the different types of artificial membranes that can be used to observe the functions of reconstituted membrane proteins, including their structure, number of transmembrane domains, and functional type. Finally, we discuss the reconstitution of membrane proteins using a cell-free synthesis system and the reconstitution and function of multiple membrane proteins.
Why Do Rumors Spread So Fast on Twitter?

This research aims to find out why rumors spread so fast on Twitter. So based on the concept of social networks and Katz Centrality, I decide to use Crawlers to collect data from Twit-ter and generate Real News Spreading Network, Rumors Spreading Network as well as graphs that illustrate their variation with post time delay. And I find that although the original size of rumors may not be as large as the original size of real news, more and more people spread rumors as time goes by, while the amount of people who read real news only grows a little. Whats more, it is users who are not very important(judging from their Katz Centrality values rank in certain news spreading networks) in the social network that play key roles in spreading the news(both rumors and real news). So I deduce that it might be ordinary users (they are not Internet celebrities, and dont have many followers) who should be aware of being informed of many rumors because they might be the key factors to spreading or stopping rumors.
Characterizations of a special family of Hq-semiclassical orthogonal q-polynomials of class one

Abstract. Our aim is to characterize a large family of Hq-semiclassical orthogonal q-polynomial sequences of class one verifying β n =(-1) n ${\beta _n=(-1)^n}$ , n≥0${n\ge 0}$ , in the three-term recurrence relation where Hq is the Hahn's operator. Four canonical situations are obtained and the study of their corresponding quadratic components which are H q 2 ${H_{q^2}}$ -classical allows us to establish the recurrence elements and integral representation and discrete measure.
Overexpression of a Short Sulfonylurea Splice Variant Increases Cardiac Glucose Uptake and Uncouples Mitochondria by Regulating ROMK Activity

The mitochondrial splice variant of the sulfonylurea receptor (SUR2A-55) is associated with protection from myocardial ischemia-reperfusion (IR) injury, increased mitochondrial ATP sensitive K+ channel activity (mitoKATP) and altered glucose metabolism. While mitoKATP channels composed of CCDC51 and ABCB8 exist, the mitochondrial K+ pore regulated by SUR2A-55 is unknown. We explored whether SUR2A-55 regulates ROMK to form an alternate mitoKATP. We assessed glucose uptake in mice overexpressing SUR2A-55 (TGSUR2A−55) compared with WT mice during IR injury. We then examined the expression level of ROMK and the effect of ROMK modulation on mitochondrial membrane potential (Δψm) in WT and TGSUR2A−55 mice. TGSUR2A−55 had increased glucose uptake compared to WT mice during IR injury. The expression of ROMK was similar in WT compared to TGSUR2A−55 mice. ROMK inhibition hyperpolarized resting cardiomyocyte Δψm from TGSUR2A−55 mice but not from WT mice. In addition, TGSUR2A−55 and ROMK inhibitor treated WT isolated cardiomyocytes had enhanced mitochondrial uncoupling. ROMK inhibition blocked diazoxide induced Δψm depolarization and prevented preservation of Δψm from FCCP perfusion in WT and to a lesser degree TGSUR2A−55 mice. In conclusion, cardio-protection from SUR2A-55 is associated with ROMK regulation, enhanced mitochondrial uncoupling and increased glucose uptake.
Low energy stopping cross section of light ions in light gases using time of flight techniques

Electronic stopping occurs when an energetic particle interacts with the electrons of a target material, causing charge exchange, excitation, and ionization of the atomic electrons and a corresponding energy loss for the impinging particle. Charge exchange between the projectile and target, in the form of electron capture and electron stripping, is the dominant mode of energy transfer for low energy projectiles in the keV region. In the case of protons in Helium gas, the difference between the ground state energy level of an ionized H atom and the first ionization energy of a Helium atom is large (11.0 eV), and so the process of electron capture is suppressed at very low energy. This leads to a reduction in the stopping cross section near this threshold, and a resultant deviation from the velocity proportionality which is otherwise characteristic of this low energy regime. The present work uses time-of-flight techniques to directly measure the stopping cross section of various target gases for the light ions H+, D+, and He+ using projectile energies between 2.4 – 22 keV/u. Measurements are obtained using a low-energy linear accelerator fed by an RF ion source at the Colorado School of Mines Department of Physics. System accuracy is checked with a projectile-target pair which has been well measured in the past using gaseous targets in the energy regime of interest (He+-N2). Data is then accumulated for several projectile-target pairs (H+-He, D+-He, H+-N2, D+-N2, H+-Ne, D+-Ne, He+-H2, He+-He, He+-Ne). Results show that the stopping cross section of H+, D+ in He does exhibit a threshold effect for projectile energies lower than ~20 keV/u. This work provides an independent measurement of this interaction, for which we find only two previous data sets below the threshold energy, and whose results differ by an order of magnitude below 6 keV/u. This work also provides measurements of several other projectile-target pairs for which there exist only limited experimental results in this very low energy regime, and provides experimental evidence of nuclear stopping effects for D+ in He gas.
The Relationship Between Co-Rumination on Social Media and Internalized Symptoms During the COVID-19 Pandemic: The Moderating Role of Balanced Time Perspective

Faced with the COVID-19 pandemic, countries have implemented stringent preventative measures. Individuals impacted by quarantine policies have become more reliant on cell phones to interact with others. It is still uncertain whether recurrent internet talks of one's struggle aggravate anxiety and despair in individuals. This study investigated the effects of social media-based co-rumination on mental health. In this study, 352 Chinese participants were recruited online, took the online test, and returned 309 valid surveys. There were 127 men and 182 women among them. The researchers looked into the relationship between respondents' co-rumination, balanced time perspective, anxiety, and depression. The study discovered that persons under quarantine had higher levels of co-rumination, but this did not result in more acute anxiety or despair. The unbalanced time perspective negatively moderated the association between the two variables, but the balanced time perspective had no moderating impact. The cognitive style of co-rumination predicted psychological disorders negatively.
A Review of Ultrathin Piezoelectric Films

Due to their high electromechanical coupling and energy density properties, ultrathin piezoelectric films have recently been intensively studied as key materials for the construction of miniaturized energy transducers, and in this paper we summarize the research progress. At the nanoscale, even a few atomic layers, ultrathin piezoelectric films have prominent shape anisotropic polarization, that is, in-plane polarization and out-of-plane polarization. In this review, we first introduce the in-plane and out-of-plane polarization mechanism, and then summarize the main ultrathin piezoelectric films studied at present. Secondly, we take perovskite, transition metal dichalcogenides, and Janus layers as examples to elaborate the existing scientific and engineering problems in the research of polarization, and their possible solutions. Finally, the application prospect of ultrathin piezoelectric films in miniaturized energy converters is summarized.
High-Energy Proton and Atmospheric-Neutron Irradiations of SiC Power MOSFETs: SEB Study and Impact on Channel and Drift Resistances

Accelerated single event burnout (SEB) tests with 200 MeV protons and atmospheric neutrons were performed for commercial silicon carbide (SiC) power MOSFETs with different architectures (i.e., planar gate, asymmetric trench, and symmetric trench). The average electric fields over the depletion layer width and the electric field distributions are reported for the tested conditions and compared for the three architectures, confirming the necessity of a lower de-rating for the trench design to protect from SEB, compared to planar ones. In addition to the epitaxial layer design, the influence of other design parameters on the SEB threshold is discussed. Finally, to investigate the presence of precursor damage in the pre-SEB region, a methodology is presented and used to study the radiation-induced degradation of the channel and drift resistances of devices that survived the SEB tests.
Identifying crown areas in an undulating area planted with eucalyptus using unmanned aerial vehicle near-infrared imagery

ABSTRACT In this letter, we propose an identification method of tree crown areas for imagery captured by a near-infrared camera on board an unmanned aerial vehicle platform over an undulating Eucalyptus planting area in Guangdong Province, China. The method extracts crown areas by applying mathematical morphology, unsupervised segmentation based on J-value segmentation, local spatial statistics, and Iterative Self-Organizing Data Analysis Technique Algorithm. Two morphology filters and four segmentation scales were compared between densely and sparsely planted plots as well as sunlit and shaded plots. The opening operation by the window size of 9×9 pixel and segmentation by the seed area sized 65×65 pixel achieved the best performance with overall accuracy of 91%, 93%, 89% and 91% in densely sunlit, sparsely sunlit, densely shaded and sparsely shaded plots.
Antibiofilm Effect of Biogenic Silver Nanoparticles Combined with Oregano Derivatives against Carbapenem-Resistant Klebsiella pneumoniae

Resistant bacteria may kill more people than COVID-19, so the development of new antibacterials is essential, especially against microbial biofilms that are reservoirs of resistant cells. Silver nanoparticles (bioAgNP), biogenically synthesized using Fusarium oxysporum, combined with oregano derivatives, present a strategic antibacterial mechanism and prevent the emergence of resistance against planktonic microorganisms. Antibiofilm activity of four binary combinations was tested against enteroaggregative Escherichia coli (EAEC) and Klebsiella pneumoniae carbapenemase-producing K. pneumoniae (KPC): oregano essential oil (OEO) plus bioAgNP, carvacrol (Car) plus bioAgNP, thymol (Thy) plus bioAgNP, and Car plus Thy. The antibiofilm effect was accessed using crystal violet, MTT, scanning electron microscopy, and Chromobacterium violaceum anti-quorum-sensing assays. All binary combinations acted against preformed biofilm and prevented its formation; they showed improved antibiofilm activity compared to antimicrobials individually by reducing sessile minimal inhibitory concentration up to 87.5% or further decreasing biofilm metabolic activity and total biomass. Thy plus bioAgNP extensively inhibited the growth of biofilm in polystyrene and glass surfaces, disrupted three-dimensional biofilm structure, and quorum-sensing inhibition may be involved in its antibiofilm activity. For the first time, it is shown that bioAgNP combined with oregano has antibiofilm effect against bacteria for which antimicrobials are urgently needed, such as KPC.
Hurricane simulation using different representations of atmosphere–ocean interaction: the case of Irene (2011)

Three approaches to represent sea surface temperatures (SSTs) in atmospheric models have been investigated using the Weather Research and Forecasting model: (1) prescribing SSTs every 6 h from reanalysis, (2) a one‐dimensional ocean mixed‐layer model and (3) a fully coupled regional ocean model. Hurricane Irene (2011) was chosen as the test case. All three options produced results comparable to observations immediately after storm passage but only options (1) and (3) captured recovery to pre‐storm conditions which suggests both are feasible approaches for long‐term simulations of tropical cyclones. Option (2) merits further investigation because of its greater computational efficiency and reduced complexity.
Studies of Skin Colour among Hybrid Subjects in Japan with Special Reference to Measurements of Sun-tanning

An attempt was made to measure the degree of natural sun-tanning among the hybrid subjects of the Elizabeth Sanders Home, Japan. The skin reflectance was measured on 69 males and 37 females, 7 to 14 years of age, in March and in September of the same year using the Photovolt photoelectric reflection meter.Although the absolute decrease in the skin reflectance during summer tended to correlate positively with the initial degree of lightness of the skin, the relative decrease as a percentage of the initial reflectance indicated a reverse tendency : the subjects of the 'negroid' origin indicated an increased darkening of the skin compared with the other subjects. In the chromaticity diagram, a tendency of increasing saturation was found for the skin-colour change through sun-tanning The significance of the data was briefly discussed.
Guided Bone Regeneration in a Periodontally Compromised Individual with Autogenous Tooth Bone Graft: A Radiomics Analysis

Background: Autogenous tooth bone graft material (AutoBT) has been advocated as a bone substitute when conducting alveolar ridge preservation. This study is aimed at using a radiomics approach in order to evaluate and testify whether AutoBT can stimulate bone growth during socket preservation in severe periodontal cases. Materials and Methods: For this study, 25 cases with severe periodontal diseases were selected. The patients’ AutoBTs were inserted into the extraction sockets and covered with Bio-Gide® collagen membranes. 3D CBCT scans and 2D X-rays were taken of the patients before surgery and after 6 months post-surgery. For the retrospective radiomics analysis, the maxillary and mandibular images were compared in different groups. Maxillary bone height was analyzed at the buccal, middle, and palatal crest sites, while the mandibular bone height was compared at the buccal, center, and lingual crest sites. Results: In the maxilla, the alveolar height was increased by −2.15 ± 2.90 mm at the buccal crest; −2.45 ± 2.36 mm at the center of the socket, and −1.62 ± 3.19 mm at the palatal crest, while the height of the buccal crest was increased by 0.19 ± 3.52 mm, and the height at the center of the socket was increased by −0.70 ± 2.71 mm in the mandible. The three-dimensional radiomics analysis demonstrated significant bone growth in the local alveolar height and high density. Conclusion: Based on clinical radiomics analysis, AutoBT could be used as an alternative bone material in socket preservation after tooth extraction in patients with severe periodontitis.
Systematical Characterization of the AT-Hook Gene Family in Juglans regia L. and the Functional Analysis of the JrAHL2 in Flower Induction and Hypocotyl Elongation

AT-hook motif nuclear localization (AHL) proteins play essential roles in various plant biological processes. Yet, a comprehensive understanding of AHL transcription factors in walnut (Juglans regia L.) is missing. In this study, 37 AHL gene family members were first identified in the walnut genome. Based on the evolutionary analysis, JrAHL genes were grouped into two clades, and their expansion may occur due to segmental duplication. The stress-responsive nature and driving of developmental activities of JrAHL genes were revealed by cis-acting elements and transcriptomic data, respectively. Tissue-specific expression analysis showed that JrAHLs had a profound transcription in flower and shoot tip, JrAHL2 in particular. Subcellular localization showed that JrAHL2 is anchored to the nucleus. Overexpression of JrAHL2 in Arabidopsis adversely affected hypocotyl elongation and delayed flowering. Our study, for the first time, presented a detailed analysis of JrAHL genes in walnut and provided theoretical knowledge for future genetic breeding programs.

Aim To compare incidence of first-ever acute cerebral infarction, etiology and traditional risk factors in young adults 15–49 years in 1988–1997 and 2008–2017 in Hordaland County, Norway. Methods Case-finding of young adults with acute cerebral infarction in 1988–1997 was done retrospectively by computer research from hospital registries in Hordaland County. Young adults with acute cerebral infarction living in the Bergen region in 2008–2017 were prospectively included in a database at Haukeland University Hospital. Traditional risk factors, etiology and modified Rankin scale score on discharge were registered. Results Crude average incidence of acute cerebral infarction was 11.4 per 100.000 per year in 1988–1997 and 13.2 per 100.000 per year in 2008–2017 (P=0.04). The prevalence of prior myocardial infarction, angina pectoris, and dyslipidemia were lower in the 2008–2017 cohort (all P<0.05). Atherosclerosis was less common in the 2008–2017 cohort (P<0.001). Conclusion The observed incidence of acute cerebral infarction in young adults increased from 1988–1997 to 2008–2017 in Hordaland County. Atherosclerosis was less common in the 2008–2017 cohort.
Fixed-Time Control for a Class of Nonlinear PH-DAE Systems

The globally fixed-time stabilization and <inline-formula> <tex-math notation="LaTeX">$H_{\infty }$ </tex-math></inline-formula> control for the port-Hamiltonian differential algebraic equation (PH-DAE) is addressed by applying the structural properties of the port-Hamiltonian (PH) systems, and the interconnection and damping assignment passivity-based control (IDA-PBC) technique. For fixed-time control design of the differential algebraic equation systems, the main obstacle lies that the algebraic variables are hidden in the system and their dynamics are ambiguous. We propose an available and effective approach to overcome this obstacle. The system variables are decomposed into differential component and the algebraic component, and the explicit representation of the dynamics of algebraic component is obtained. Fist, we investigate the locally fixed-time stabilization control as well as globally attractive for PH-DAE. Second, we focus on solving the globally fixed-time stabilization and <inline-formula> <tex-math notation="LaTeX">$H_{\infty }$ </tex-math></inline-formula> control problems by jointly taking advantage of the locally fixed-time stabilization control for the origin and the globally fixed-time attractivity control for a predeterminate region. Finally, in order to address fixed-time stabilization control and <inline-formula> <tex-math notation="LaTeX">$H_{\infty }$ </tex-math></inline-formula> control for PH-DAE, new controllers are designed. Moreover, the convergence time of systems can be easily estimated after external disturbance vanishes. The efficiency of the theoretical results acquired in present article is verified via two examples with numerical simulation.
New algorithm of infrared image enhancement based on histogram nonlinear extension

Because of the influence of conduction of heat and environment and the limitation of the infrared imaging system, the contrast of infrared image is low, and the edge is commonly. Hereinto, the typical example is that the distribution of image histogram is excessively concentrated. Algorithm of image nonlinear extension enhancement based on distributing characteristic of histogram is presented, which spreads the uneven longitudinal arranging idea of image pressing\|extension digitalization into the uneven transverse extension of the image histogram. On the basis of presentation of algorithm, the enhancing effect of it is contrasted with that of histogram linear extension algorithm. \;
