Traditional adhesives with strong adhesion are widely applied in the fields of wood, building, and electronics. However, synthesis usage commercial not eco-friendly, which harmful to human health environment. In this study, a green cellulose nanofibrils/poly(hydroxyethyl methacrylate-co-dopamine methacrylamide) (CNFs/P(HEMA-co-DMA)) adhesive excellent biocompatibility bonding strength has been fabricated. P(HEMA-co-DMA) catechol content 7.1 mol % was synthesized using dopamine methacrylamide...

Abstract An adaptive observer is a recursive algorithm for joint state–parameter estimation of parameterized state‐space systems. Previous works on globally convergent observers consider unknown parameters either in state equations or output equations, but not both them. In this paper, new designed linear time‐varying systems with and equations. Its global convergence simultaneous states formally established under appropriate assumptions. A numerical example presented to illustrate the...

Abstract Numerous traditional adhesives have good adhesion in dry environments. However, non‐environmental‐friendliness and poor water resistance largely limit their practical applications. To prepare biocompatible with strong strength, this paper, catechol‐functionalized cellulose‐based adhesive polymers are synthesized by grafting N ‐(3,4‐dihydroxyphenethyl)methacrylamide methyl methacrylate onto cellulose chain through atom transfer radical polymerization (ATRP). The successful synthesis...

Abstract This work aimed to evaluate the in vitro adhesive and immunoregulative effects of water-in-oil-in-water (W/O/W) microencapsulated Lactiplantibacillus plantarum L3 after subjected yoghurt stress. The W/O/W L. was prepared dropped into fresh milk with commercial starters (Streptococcus thermophilus Lactobacillus delbrueckii subsp. bulgaricus). stored at 4 °C for 21 days. storage simulated gastrointestinal treatment on immunomodulatory activities were investigated. Results showed that...

Summary Relationship between intestinal flora and obesity has aroused great interest. The probiotic effects of Lactobacillus plantarum ( LP ) fermentum LF have been documented extensively. This study aimed to explore the alone or in combination on lipid‐lowering high‐fat diet rat via modulation systemic immunity. rats plus 10 8 cfu day −1 showed significantly lower IL ‐6 endotoxin ET content, increased number Bifidobacterium decreased liver steatosis fat vehicle sizes. can regulate immune...

A digital dual-mode linear quadratic regulator (LQR) with feedforward optimal controller is presented, which allows voltage control of a boost converter for wide-load-range condition, whether in continuous conduction mode (CCM) or discontinuous (DCM). Based on the conventional LQR method, proposed designed and makes following two improvements. First, order to eliminate phase error caused by right-half-phase zero emerged non-minimum converter, implemented tracking technique because inverse...

Upper back pain originating from the cervical disk itself is defined as discogenic upper pain. Coblation procedures can provide therapeutic effects for neck and radicular related to contained herniation. However, no studies have reported performance of coblation procedures, particularly treating The purpose this study was evaluate efficacy in In a prospective, clinical, observational study, 28 consecutive patients with underwent on percutaneous anterior approach. Pain visual analogue scale...

Introduction: Seeking effective multimodal analgesia and anesthetic regimen is the basis for success of ERAS. Opioid-free anesthesia (OFA) a associating hypnotics, N-methyl-D-aspartate (NMDA) antagonists, local anesthetics, anti-inflammatory drugs α-2 agonists. Although previous studies have confirmed that OFA safe feasible VATS surgery, there great heterogeneity in how to select combine anti-harm replace opioids. We hypothesized reduced opioid use during after surgery allowed by compared...

For a class of uniformly observable nonlinear multi-input-multi-output (MIMO) systems with unknown parameters in both state and output equations, an adaptive observer is designed constructive manner based on the techniques high gain estimation. The for joint parameter estimation conceptually simple. new algorithm makes use time varying matrix estimation, which simplifies initialization tuning. In order to establish global exponential convergence observer, persistent excitation condition...
