description: Soft tissue trauma of skeletal muscle is one of the most common side effects in surgery. Muscle injuries are not only caused by accident-related injuries but can also be of an iatrogenic nature as they occur during surgical interventions when the anatomical region of interest is exposed. If the extent of trauma surpasses the intrinsic regenerative capacities, signs of fatty degeneration and formation of fibrotic scar tissue can occur, and, consequentially, muscle function deteriorates or is diminished. Despite research efforts to investigate the physiological healing cascade following trauma, our understanding of the early onset of healing and how it potentially determines success or failure is still only fragmentary. This review focuses on the initial physiological pathways following skeletal muscle trauma in comparison to bone and tendon trauma and what conclusions can be drawn from new scientific insights for the development of novel therapeutic strategies. Strategies to support regeneration of muscle tissue after injury are scarce, even though muscle trauma has a high incidence. Based on tissue specific differences, possible clinical treatment options such as local immune-modulatory and cell therapeutic approaches are suggested that aim to support the endogenous regenerative potential of injured muscle tissues.

description: Three hidden-charm pentaquark $P_c$ states, $P_c(4312)$, $P_c(4440)$, and $P_c(4457)$ were revealed in the $Λ_b^0\to J/ψp K^-$ process measured by LHCb using both run I and run II data. Their nature is under lively discussion, and their quantum numbers have not been determined. We analyze the $J/ψp$ invariant mass distributions under the assumption that the crossed-channel effects provide a smooth background. For the first time, such an analysis is performed employing a coupled-channel formalism with the scattering potential involving both one-pion exchange as well as short-range operators constrained by heavy quark spin symmetry. We find that the data can be well described in the hadronic molecular picture, which predicts seven $Σ_c^{(*)}\bar D^{(*)}$ molecular states in two spin multiplets, such that the $P_c(4312)$ is mainly a $Σ_c\bar D$ bound state with $J^P=1/2^-$, while $P_c(4440)$ and $P_c(4457)$ are $Σ_c\bar D^*$ bound states with quantum numbers $3/2^-$ and $1/2^-$, respectively. We also show that there is evidence for a narrow $Σ_c^*\bar D$ bound state in the data which we call $P_c(4380)$, different from the broad one reported by LHCb in 2015. With this state included, all predicted $Σ_c \bar D$, $Σ_c^* \bar D$, and $Σ_c \bar D^*$ hadronic molecules are seen in the data, while the missing three $Σ_c^*\bar D^*$ states are expected to be found in future runs of the LHC or in photoproduction experiments.

description: Photonic band gap (PBG) materials are attractive for cavity QED experiments because they provide extremely small mode volumes and are monolithic, integratable structures. As such, PBG cavities are a promising alternative to Fabry-Perot resonators. However, the cavity requirements imposed by QED experiments, such as the need for high Q (low cavity damping) and small mode volumes, present significant design challenges for photonic band gap materials. Here, we pose the PBG design problem as a mathematical inversion and provide an analytical solution for a two-dimensional crystal. We then address a planar (2D crystal with finite thickness) structure using numerical techniques.

description: Background: The last decades have seen great advances in the understanding, treatment, and prevention of cardiovascular disease (CVD). Although mortality rates due to CVD have declined significantly in the last decades, the burden of CVD is still high, particularly in older adults. This raises the question whether contemporary populations of older adults are experiencing better or worse objective as well as subjective health than earlier-born cohorts. The aim of this study was to examine differences in modifiable indicators of cardiovascular health (CVH), comparing data obtained 20 years apart in the Berlin Aging Study (BASE, 1990-93) and the Berlin Aging Study II (BASE-II, 2009-2014). Methods: Serial cross-sectional analysis of 242 propensity-score-matched participants of BASE (born 1907-1922) and BASE-II (born 1925-1942). Body mass index (BMI), blood pressure, total cholesterol, glycated hemoglobin (HbA1c), diet, smoking and physical activity were operationalized according to the "Life's simple 7" (LS7) criteria of the American Heart Association. Results: 121 matched pairs were identified based on age, sex, and education. In the later-born BASE-II sample, the mean LS7 score was significantly higher than in the earlier-born sample (7.8 +/- 1.8 vs. 6.4 +/- 2.1, p<0.001), indicating better CVH. In detail, diet, physical activity, smoking, cholesterol, and HbA1c were more favorable, whereas blood pressure was significantly higher in individuals from the later-born cohort. BMI did not differ significantly between the two matched samples. Notably, despite better CVH, later-born individuals (BASE-II) reported lower self-rated health, presumably because of higher health expectations. Conclusions: Overall, cardiovascular health was significantly better in the later-born cohort, but several notable exceptions exist.

description: Genus Echinolittorina Habe, 1956
 Nodilittorina (Echinolittorina) Habe, 1956: 96–99 (type by original designation Litorina tuberculata Menke, 1828; cited as Echinolittiorina in error, p. 96).
 Diagnosis: Shell aragonitic; nodulose, granulose, spirally striate or entirely smooth; if smooth or striate then usually with dark axial stripes or axially aligned series of dashes; eroded parietal area may be present, sometimes a small pseudumbilicus; aperture dark with pale spiral band at base (i.e. anterior end) and sometimes another posteriorly. Cephalic tentacles with 2–3 longitudinal black lines, all black, or with broad transverse band at base distal to eye. Operculum paucispiral. Penis with blade-shaped filament (rarely swollen); base usually bifurcate (not so if mamilliform gland absent); usually a single mamilliform gland (sometimes absent, rarely 2); glandular disc of subepithelial glandular tissue usually present; penial vas deferens an open groove or rarely a closed tube. Rod-pieces of paraspermatozoa usually long and straight (rarely small and irregular, or curved). In pallial oviduct egg groove makes a simple loop through albumen gland, straight path through capsule gland and jelly gland; copulatory bursa opens in anterior or posterior position within straight section of pallial oviduct. Spawn a biconvex pelagic capsule with cupola-shaped upper side sculptured by concentric rings, containing single egg; development planktotrophic. Outer marginal radular tooth with flange at inside and usually also at outside of base. Distribution worldwide tropical and warm temperate. (Modified from Reid 2007.)
 Remarks: The taxonomic history of this genus has been summarized by Reid (2007). Since the molecular phylogeny of Echinolittorina species by Williams & Reid (2004) a revised analysis with addition of new sequences (including the new species described herein, making a complete analysis of all 60 known members worldwide) has been published (Williams & Duda 2008; Fig. 1). Monographs are available of the eastern Pacific species [Reid 2002b; as ‘ Nodilittorina ’, but Austrolittorina fernandezensis (Rosewater, 1970) and A. araucana (d’Orbigny, 1840) are now excluded (Williams et al. 2003)] and of the Indo-Pacific species (Reid 2007).

Study $ω$ and $ϕ$ photoproduction in the nucleon isotopic channels

description: We present results for the photoproduction of $ω$ and $ϕ$ meson in the nucleon isotopic channles. A recently developed quark model with an effective Lagrangian is employed to account for the non-diffractive {\it s}- and {\it u}-channel processes; the diffractive feature arising from the {\it natural} parity exchange is accounted for by the {\it t}-channel pomeron exchange, while the {\it unnatural} parity exchange is accounted for by the {\it t}-channel pion exchange. In the $ω$ production, the isotopic effects could provide more information concerning the search of "missing resonances", while in the $ϕ$ production, the isotopic effects could highlight non-diffractive resonance excitation mechanisms at large angles.

Geometrical behavior of WH solutions are discussed in both anisotropic and isotropic cases respectively. Also, the stability of this model is obtained by determining the equilibrium condition. The radial null energy condition and weak energy condition are validated in the proposed shape function indicating the absence of exotic matter in modified $f(R,T)$ gravity.

description: Body temperature is a valuable parameter in determining the wellbeing of laboratory animals. However, using body temperature to refine humane endpoints during acute illness generally lacks comprehensiveness and exposes to inter-observer bias. Here we compared two methods to assess body temperature in mice, namely implanted radio frequency identification (RFID) temperature transponders (method 1) to non-contact infrared thermometry (method 2) in 435 mice for up to 7 days during normothermia and lipopolysaccharide (LPS) endotoxin-induced hypothermia. There was excellent agreement between core and surface temperature as determined by method 1 and 2, respectively, whereas the intra-and inter-subject variation was higher for method 2. Nevertheless, using machine learning algorithms to determine temperature-based endpoints both methods had excellent accuracy in predicting death as an outcome event. Therefore, less expensive and cumbersome non-contact infrared thermometry can serve as a reliable alternative for implantable transponder-based systems for hypothermic responses, although requiring standardization between experimenters.

description: A detailed study of the Counter-Rotating Model (CRM) for generic electrostatic (magnetostatic) axially symmetric thin disks without radial pressure is presented. We find a general constraint over the counter-rotating tangential velocities needed to cast the surface energy-momentum tensor of the disk as the superposition of two counter-rotating charged dust fluids. We then show that this constraint is satisfied if we take the two counter-rotating streams as circulating along electrogeodesics with equal and opposite tangential velocities. We also find explicit expressions for the energy densities, electrostatic (magnetostatic) charge densities and velocities of the counter-rotating fluids. Three specific examples are considered where we obtain some CRM well behaved based in simple solutions to the Einstein-Maxwell equations. The considered solutions are Reissner-Nordstrom in the electrostatic case, its magnetostatic counterpart and two solutions obtained from Taub-NUT and Kerr solutions.

description: Supersymmetric Yang-Mills-theories with local gauge coupling have a new type of anomalous breaking, which appears as a breaking of supersymmetry in the Wess-Zumino-gauge. The anomalous breaking generates the two-loop order of the gauge $β$-function in terms of the one-loop $β$-function and the anomaly coefficient. We determine the anomaly coefficient in the Wess-Zumino-gauge by solving the relevant supersymmetry identities. For this purpose we use a background gauge and show that the anomaly coefficient is uniquely determined by convergent one-loop integrals. When evaluating the one-loop diagrams in the background gauge, it is seen that the anomaly coefficient is determined by the Feynman-gauge value of the one-loop vertex function to the topological term $G \tilde G$ at vanishing momenta.

description: This paper firstly introduced the two stage supply chain consisting of single agricultural product producer and fund restraint retailer. Then, it analyzed the influence of bank interest rate on order quantity, wholesale price and expected profit of retailer and producer on the condition of retailer taking external loan strategy. Studies have shown that when the bank interest rate is in (0, 0.9), the order quantity of agricultural products is a decreasing function of bank interest rate; when the bank interest rate is in (0, 1), wholesale price of agricultural products decreases with increase in the bank interest rate; when the bank interest rate is in (0, 0.6), the expected profit of retailer is a decreasing function of bank interest rate; when the bank interest rate is in (0, 1), the expected profit of producer decreases with increase in the bank interest rate. Finally, through simulation calculation examples, it verified suitability of the conclusion, in the hope of providing reference and application value for management of supply chain.

For a choice of the projection condition on the Killing spinors of the BPS solutions, first order differential equations governing the flow of the scalars are derived. With these equations, we analyze the equations of motion and determine conditions under which gauged supergravity theories may admit Einstein domain wall solutions.

description: Like the general green supply chain, the green supply chain of fruits and vegetables also requires low negative effects of the environment and high resource utilization rate, as well as the healthiness and freshness of fruits and vegetables. Currently, the level of development of the green supply chain of fruits and vegetables is low in China, and the freshness of fruits and vegetables can not be well maintained, so there is an urgent need to improve the operational efficiency of the green supply chain of fruits and vegetables. The operational efficiency of the green supply chain of fruits and vegetables is affected by many factors, and the most important factor is the incomplete consistency between the individual interests of supply chain members and the overall interests of supply chain. Therefore, the key driving force to improve the efficiency of green supply chain of fruits and vegetables is to build the scientific and rational collaborative decision-making mechanism of supply chain, in order to solve the problems concerning the green supply chain of fruits and vegetables, such as risk sharing, cost control and revenue allocation, thereby achieving the coordinated development of the green supply chain of fruits and vegetables.

description: Takagi-Sugeno-Kang (TSK) fuzzy systems are flexible and interpretable machine learning models; however, they may not be easily optimized when the data size is large, and/or the data dimensionality is high. This paper proposes a mini-batch gradient descent (MBGD) based algorithm to efficiently and effectively train TSK fuzzy classifiers. It integrates two novel techniques: 1) uniform regularization (UR), which forces the rules to have similar average contributions to the output, and hence to increase the generalization performance of the TSK classifier; and, 2) batch normalization (BN), which extends BN from deep neural networks to TSK fuzzy classifiers to expedite the convergence and improve the generalization performance. Experiments on 12 UCI datasets from various application domains, with varying size and dimensionality, demonstrated that UR and BN are effective individually, and integrating them can further improve the classification performance.

description: Since the reform and opening-up, economy of mountain areas in China has realized considerable development. However, due to such factors as terrain, traffic, and individual differences, compared with plain and coastal areas, mountain areas still lag far behind. In recent years, informationization construction of China develops rapidly, but it nearly stagnates in mountain rural areas. Information has become an essential factor restricting economic development of rural areas. Based on the survey of current information demand of farmers carried out in Pingshan County in Hebei Province in 2010, this study came up with relevant recommendations, in order to speed up development of rural economic in mountain areas, narrow the regional gap, improve living condition of farmers in mountain areas, and increase income level of farmers in mountain areas.

description: Objective Descemet membrane endothelial keratoplasty (DMEK) remains a challenging technique. We compare the precision of femtosecond laser-assisted DMEK to manual DMEK. Methods and Analysis A manual descemetorhexis (DR) of 8 mm diameter was compared with a femtosecond laser-assisted DR of the same diameter (femto-DR) in 22 pseudophakic patients requiring DMEK. We used OCT images with a centred xy-diagram to measure the postoperative precision of the DR and the amount of endothelial denuded area. Endothelial cell loss (ECL) and best corrected visual acuity were measured 3 months after surgery. Results In the manual group, the median error of the DR was 7% (range 3%-16%) in the x-diameter and 8% (range 2%-17%) in the y-diameter. In the femto group, the median error in the respective x and y-diameters was 1% (range 0.4%-3%) and 1% (range 0.006%-2.5%), smaller than in the manual group (p=0.001). Endothelial denuded areas were larger in the manual group (11.6 mm(2), range 7.6-18 mm(2)) than in the femto group (2.5 mm(2), range 1.25.9 mm(2)) (p<0.001). The ECL was 21% (range 5%-78%) in the manual DR and 17% (range 6%-38%) in the femto-DR group (p=0.351). The median visual acuity increased from 0.4 logMAR (range 0.6-0.4 logMAR) in both groups to 0.1 logMAR (range 0.4-0 logMAR) in the manual group and to 0.1 logMAR (range 0.3-0 logMAR) in the femto group (p=0.461). Three rebubblings were required in the manual group, whereas the femto group required only one. Conclusion The higher precision of the femto-DR bears the potential to improve DMEK surgery.

description: Using quantile regression method, this paper made an empirical analysis on convergence of China’s regional economic growth since the reform and opening-up. It firstly introduced principle of quantile regression method and related theories of convergence of economic growth. Through discussing interprovincial variation coefficient of GDP per capita, it carried out convergence analysis on economic growth and divided 3 decades since the reform and opening-up into 3 stages. Then, it made a comparative analysis of absolute β convergence on 3 stages using least-squares estimation and quantile regression method, and also stressed the advantage of quantile regression method. On this basis, it made an in-depth study on conditional β convergence at 3 stages. Empirical results indicate that there is absolute and conditional convergence at the first stage, no convergence at the second stage, and weak convergence at the third stage. Finally, it discussed weak points in this study and came up with recommendations for future studies.

description: The family of $n$-bit Toffoli gates, with the two-bit Toffoli gate as the figurehead, are of great interest in quantum information as they can be used as universal gates and in quantum error correction, among other things. We present a single-step implementation of arbitrary $n$-bit Toffoli gates (up to a local change of basis), based on resonantly driving a single qubit that has a strong Ising coupling to $n$ other qubits. The setup in the two-qubit case turns out to be identical to the universal Barenco gate. The gate time and error are, in theory, independent of the number of control qubits, scaling better than conventional circuit decompositions. We note that our assumptions, namely strongly coupling $n+1$ qubits and a driving frequency that scales with $n$, may break down for large systems. Still, our protocol could enhance the capabilities of intermediate scale quantum computers, and we discuss the prospects of implementing our protocol on trapped ions, Rydberg atoms, and on superconducting circuits. Simulations of the latter platform show that the Toffoli gate with two control bits attains fidelities of above 0.98 even in the presence of decoherence. We also show how similar ideas can be used to make a series of controlled-\textsc{not}-gates in a single step. We show how these can speed up the implementation of quantum error correcting codes and we simulate the encoding steps of the three-qubit bit-flip code and the seven-qubit Steane code.

description: Expression of the opioid peptide genes proopiomelanocortin (Pomc), proenkephalin (Penk), and prodynorphin (Pdyn), in immune cells plays a key role in endogenous pain control. In a rat model of painful unilateral paw inflammation, we isolated cells from popliteal lymph nodes and evaluated the role of C(p)G island C5-methylation on the transcriptional activation of those genes. Using methylated DNA immunoprecipitation, we sorted gDNA into methylated (me) and non-me fractions and then determined the C(p)G island methylation status of each fraction via quantitative Real Time-PCR (qRT-PCR). In silico analysis by MethPrimer software identified one C(p)G island in Pdyn and three each in Pomc and Penk. No substantial changes in C5-methylation of any gene were observed. In conclusion, the C(p)G island methylation status does not seem to be a key regulator of opioid gene activation in immune cells during peripheral tissue inflammation.

description: Foreign power interference in domestic elections is an existential threat to societies. Manifested through myriad methods from war to words, such interference is a timely example of strategic interaction between economic and political agents. We model this interaction between rational game players as a continuous-time differential game, constructing an analytical model of this competition with a variety of payoff structures. All-or-nothing attitudes by only one player regarding the outcome of the game lead to an arms race in which both countries spend increasing amounts on interference and counter-interference operations. We then confront our model with data pertaining to the Russian interference in the 2016 United States presidential election contest. We introduce and estimate a Bayesian structural time series model of election polls and social media posts by Russian Twitter troll accounts. Our analytical model, while purposefully abstract and simple, adequately captures many temporal characteristics of the election and social media activity. We close with a discussion of our model's shortcomings and suggestions for future research.

description: Rotating disks with nonzero radial pressure and finite radius are studied. The models are based in the Taub-NUT metric and constructed using the well-known ``displace, cut and reflect'' method. We find that the disks are made of perfect fluids with constant energy density and pressure. The energy density is negative, but the effective Newotnian density is possitive as the strong energy condition requires. We also find that the disks are not stable under radial perturbations and that there are regions of the disks where the particles move with superluminal velocities.

description: Background: Remimazolam is an ultra-short acting benzodiazepine under development for procedural sedation and general anesthesia. It is hydrolyzed by CES1 to an inactive metabolite (CNS7054). Purpose: In this study, the effect of continuous remimazolam exposure on its metabolism and on CES1 expression was investigated in a dynamic 3-D bioreactor culture model inoculated with primary human hepatocytes. Methods: Remimazolam was continuously infused into bioreactors for 5 days at a final concentration of 3,000 ng/ml (6.8 μM). In parallel, 2-D cultures were run with cells from the same donors, but with discontinuous exposure to remimazolam. Results: Daily measurement of clinical chemistry parameters (glucose, lactate, urea, ammonia, and liver enzymes) in culture supernatants indicated no noxious effect of remimazolam on hepatocyte integrity as compared to untreated controls. Concentrations of remimazolam reached steady-state values of around 250 ng/ml within 8 hours in 3-D bioreactors whereas in 2-D cultures remimazolam concentrations declined to almost zero within the same time frame. Levels of CNS7054 showed an inverse time-course reaching average values of 1,350 ng/ml in perfused 3-D bioreactors resp. 2,800 ng/ml in static 2-D cultures. Analysis of mRNA expression levels of CES1 indicated no changes in gene expression over the culture period. Conclusion: The results indicated a stable metabolism of remimazolam during 5 days of continuous exposure to clinically relevant concentrations of the drug. Moreover, there was no evidence for a harmful effect of remimazolam exposure on the integrity and metabolic activity of in vitro cultivated primary human hepatocytes.

description: The quantitative evaluation on land use/cover change as well as its influence on landscape pattern under the background of returning grain plots to forestry is significant to the sustainable utilization of land resources and ecological environment reconstruction in the southern Ningxia. Based on multi-temporal remote sensing data from four periods of Landsat TM/ETM, and combination of ecological quantity analytical method with GIS, the change of land use/cover and landscape pattern in Pengyang County of Ningxia Province were analyzed. The conclusions showed that the amount of each land use type was changed with different degrees, the area of forest/grass land increased, while farmland and unused land decreased. The change of landscape pattern was characterized as that the degree of landscape fragmentation, mixed distribution of patches, diversity index and evenness index increased gradually and then decreased, the connectivity between patches decreased gradually and then increased, and landscape shape presented irregular.

description: The prevalence of sleep disordered breathing (SDB) after acute myocardial infarction (AMI) is high. However, little is known about predominant SDB type and the impact of SDB severity on arrhythmogenesis. We conducted a prospective single-center observational study and performed an unattended sleep study and Holter monitoring within 10 days after AMI, and an unattended sleep study 11.3 months after AMI. All patients were included from the Department of Cardiology at the University Hospital Schleswig-Holstein, Lübeck, Germany. A total of 202 subjects with AMI (73.8% with ST-elevation; 59.8 years; 73.8% male) were included. The mean BMI was 27.8 kg/m2 and the mean neck/waist circumference was 41.7/103.3 cm. The mean left ventricular ejection fraction was 56.6%. The SDB prevalence defined as apnoea-hypopnea-index (AHI) ≥ 5/h was 66.7% with 44.9% having central (CSA), and 21.8% obstructive sleep apnoea (OSA). The mean AHI was 13.8 1/h. In 10.2% nsVT was detected in the Holter monitoring. AI >23/h was independently associated with higher risk of nsVT in the subacute AMI period. SDB is highly prevalent and CSA a predominant type of SDB in the subacute phase after uncomplicated AMI treated with modern revascularization procedures and evidence-based pharmacological therapy. Severe SDB is independently associated with higher risk for nsVT in the subacute AMI period and its course should be monitored as it can potentially have a negative impact on relevant outcomes of AMI patients. Further prospective studies are needed to assess long-term follow up of SDB after AMI and its impact on mortality and morbidity.

description: In our recently proposed quantum theory of gravity, the universe is made of `atoms' of space-time-matter (STM). Planck scale foam is composed of STM atoms with Planck length as their associated Compton wave-length. The quantum dispersion and accompanying spontaneous localisation of these STM atoms amounts to a cancellation of the enormous curvature on the Planck length scale. However, an effective dark energy term arises in Einstein equations, of the order required by current observations on cosmological scales. This happens if we propose an extremely light particle having a mass of about $10^{-33} \ {\rm eV/c^2}$, forty-two orders of magnitude lighter than the proton. The holographic principle suggests there are about $10^{122}$ such particles in the observed universe. Their net effect on space-time geometry is equivalent to dark energy, this being a low energy quantum gravitational phenomenon. In this sense, the observed dark energy constitutes evidence for quantum gravity. We then invoke Dirac's large number hypothesis to also propose a dark matter candidate having a mass halfway (on the logarithmic scale) between the proton and the dark energy particle, i.e. about $10^{-12}\ {\rm eV/c^2}$.

description: We investigate critical wetting transitions for fluids adsorbed in wedge-like geometries where the substrate height varies as a power-law, $z(x,y) \sim |x| ^γ$, in one direction. As $γ$ is increased from 0 to 1, the substrate shape is smoothly changed from a planar-wall to a linear wedge. The continuous wetting and filling transitions pertinent to these limiting geometries are known to have distinct phase boundaries and critical singularities. We predict that the intermediate critical wetting behaviour occurring for $0
