In modern optics,light can be described at different levels:as rays,as scalar waves,as vector fields,and as quantum *** the first three levels,there are singularities—characteristic features,useful in interpreting phenomena at that *** geometrical optics,the singularities are ray caustics;in scalar wave optics,they are phase singularities(=wave dislocations=wave vortices=nodal manifolds);in vector waves,they are singularities where the polarisation of light is purely linear or purely *** singularities at each level are dissolved at the next *** singularities occur in all waves,not just light.

Dear Editor,This letter concerns the parameter tuning problem for nonlinear satellite buffer networks with communication delays, aiming to optimize their stability properties under L_(1)-gain. We first model the satellite buffer networks by a nonlinear time-delay positive system and propose a novel characterization under which the nonlinear system is asymptotically stable with a prescribed L_(1)-induced performance.

This paper studies the countermeasure design problems of distributed resilient time-varying formation-tracking control for multi-UAv systems with single-way communications against composite attacks,including denial-of-services(DoS)attacks,false-data injection attacks,camouflage attacks,and actuation attacks(AAs).Inspired by the concept of digital twin,a new two-layered protocol equipped with a safe and private twin layer(TL)is proposed,which decouples the above problems into the defense scheme against DoS attacks on the TL and the defense scheme against AAs on the cyber-physical ***,a topologyrepairing strategy against frequency-constrained DoS attacks is implemented via a Zeno-free event-triggered estimation scheme,which saves communication resources *** upper bound of the reaction time needed to launch the repaired topology after the occurrence of DoS attacks is ***,a decentralized adaptive and chattering-relief controller against potentially unbounded AAs is ***,this novel adaptive controller can achieve uniformly ultimately bounded convergence,whose error bound can be given *** practicability and validity of this new two-layered protocol are shown via a simulation example and a UAv swarm experiment equipped with both Ultra-WideBand and WiFi communication channels.

Early embryonic imaging of cardiovascular development in mammalian models requires a methodthat can penetrate through and distinguish the many tissue layers with high spatial and temporalresolution. In this paper we evaluate the capability of Optical Coherence Tomography (OCT)technique for structural 3D embryonic imaging in mouse embryos at different stages of thedevelopmental process ranging from 7.5 dpc up to 10.5 dpc. Obtained results suggest that thecollected data is suitable for quantitative and qualitative measurements to assess cardiovascularfunction in mouse models, which is likely to expand our knowledge of the complexity of theembryonic heart, and its development into an adult heart.

Treatment for inflammatory bowel disease (IBD) often requires specialized *** much of IBD care has shifted to the outpatient setting, hospitalizationsremain a major site of healthcare utilization and a sizable proportion of patientswith inflammatory bowel disease require hospitalization or surgery during theirlifetime. In this review, we approach IBD care from the population-level with aspecific focus on hospitalization for IBD, including the shifts from inpatient tooutpatient care, the balance of emergency and elective hospitalizations, regionalizationof specialty IBD care, and contribution of surgery and endoscopy tohospitalized care.

Production of proinflammatory cytokines in the central nervous system is a key process in the neuroinflammatory response to trauma,infection,and neurodegenerative diseases(Kumar,2019).These intercellular signaling molecules play multiple roles in the immune response in the central nervous system including the orchestration of the sickness response to innate immune perturbations in the brain(Dantzer et al.,2008).

Green method for preparation of ion-conducting membranes(ICM) based on bacterial cellulose nanofibers(CNF) modified by a copolymer of sodium acrylate and 2-acrylamido-2-methylpropanesulfonic acid was elaborated. FTIR and NMR data confirmed grafting of polyacrylate onto cellulose surface. Formation of porous structure of the ICM was controlled by SEM and AFM. The maximal ionic conductivity of the membranes reaches 1.5 and 3.1 mS·cm^(-1)(60 ℃ and 98% relative humidity) when they are saturated with water or H_2SO_4(1 mol·L^(-1)) electrolyte,respectively. Prepared ICM was tested as a separator in a symmetrical supercapacitor with electrodes based on polyaniline hydrogel. The assembled cell demonstrate ability to operate at high current density up to 100 A·g^(-1) maintaining specific capacitance 165 F·g^(-1). Maximal specific capacitance of 289 F·g^(-1) was achieved at current density 1 A·g^(-1). Retaining of 90% of initial capacitance after 10000 of charge-discharge cycles proves high electrochemical stability of prepared ICM.

In this study,we determined the levels of cytokine secretory inhibitors and the microbiota biofilms of semen from healthy and infertile subjects.A total of 118 clinical bacterial isolates were isolated and *** secretory inhibitors were determined based on the difference in cytokine content between the control and experimental samples of cell-free supernatants of isolated *** formation was studied by determining the adhesion of microorganisms to the surface of a 96-well sterile plate and expressed as the optical density at 630 nm(OD_(630)).Cell-free supernatants of Staphylococcus contained higher levels of secretory inhibitor of cytokines in conditionally healthy than in infertile *** contrast,in infertile men,the ability to reduce cytokine levels was more characteristic of Enterococcus and *** Staphylococcus,Corynebacterium,and Enterococcus isolated from infertile subjects showed a greater ability to form biofilms than the same bacteria isolated from healthy *** research is needed on this topic,since it is necessary to determine the relationships between decreased secretory inhibitors of cytokines,production of biofilms by bacteria in semen,and *** is likely that the ability of microorganisms to change the concentration of cytokines and increase the level of biofilm formation in semen may be associated with minimal impairments of fertilizing ability,which are not detected using other methods.
