Dynamic analysis of viscoelastic tuned mass damper system under harmonic excitation

The purpose of this paper is to investigate the contribution of viscoelastic material (VEM) to the control performance of the viscoelastic tuned mass damper (VTMD). Firstly, the equivalent fractional derivation Kelvin model is used to describe the frequency dependence of viscoelasticity in VTMD, and an index is proposed to characterize the level of frequency dependence. Then the effects of the high loss factor of VEM and frequency dependence of viscoelasticity on the effectiveness and robustness of VTMD control are analyzed by numerical examples. At last, a design strategy for VTMD is proposed to select the type of VEM and optimize its stiffness contribution. The results show that the frequency dependence of shear storage modulus of VEM is beneficial to further reduce the dynamic response of the primary structure equipped with VTMD, and the loss factor of VEM determines the optimum frequency ratio and control effect of VTMD. Compared to the conventional tuned mass damper, VTMD has a better robustness for the positive error of the natural frequency of VTMD but has a worse robustness for the negative error. The frequency dependence of shear storage modulus of VEM is beneficial to the robustness of VTMD for both the positive and negative errors of the natural frequency of the primary structure. The VEM with a strong frequency dependence of shear storage modulus is the ideal VEM for VTMD, and the proposed design strategy can deal with the trade-off between the control effectiveness and control robustness of VTMD.
Time-varying SNP distribution and portfolio performance

First, we propose a novel method in the operations research of portfolio selection based on equity screening rules determined by performance measures (PMs) under a framework of time-varying (TV) semi-nonparametric (SNP) densities for asset returns with conditional volatility such as the popular GJR speci cation. The TV-SNP density, as well as providing an improved t of the return tail dynamics due to the exibility driven by the TV higher-order moments, allows for tractable closed-form expressions of both conditional reward and risk measures, speci cally partial moments and expected shortfall. Second, as a result, we show that some conditional PMs such as Rachev and skewness-kurtosis ratios yield portfolios that dominate, in our out-of-sample (OOS) empirical study for stocks from the S&P 100 index, those under the conditional Sharpe, Sortino and Omega ratios. Third, we highlight as cutting-edge the use of conditional copula models to provide more evidence on the tail dependence of the OOS portfolio return distributions under di¤erent PMs with respect to the benchmark Sharpe ratio portfolio. Finally, a strict robustness analysis hinged on alternative portfolio rebalancing frequencies and weighting schemes is also carried out.
TRENDS AND PERIODICITY IN THE LONGEST INSTRUMENTAL RAINFALL SERIES FOR THE AREA OF MOST EXTREME RAINFALL IN THE WORLD NORTHEAST INDIA

ABSTRACT: The longest instrumental rainfall series have been investigated for theNorth Assam subdivision and 4 meteorological stations in Northeast India. Analysis of trends to annual and seasonal rainfall show these to be very stable, with no change in therainfall over North Assam during the last 150 years. The Fourier analysis of fluctuations in rainfall series shows that the periodic signal of T=3.5 year is the strongest one. Such a signal, with the same phase, has been found for all rainfall stations of the North Assamsubdivision and in all investigated seasons. KEY WORDS: monsoon rainfall, trend, periodicity, northeast India. INTRODUCTION Studies of the annual/summer (south-west) monsoon variability on rainfallover India have a long history. Blanford (1886) first prepared annual rainfall se-ries for British India, while Walker (1910) first analyzed the summer monsoonseries for the period 1841-1908 and reported that no trend could be observed.Later many authors analyzed rainfall series for periods of different length usingdata from different raingauge networks. Parthasarathy and Mooley (1978) foundthat no trend was to be noted in the all-India annual monsoon rainfall series. By analyzing 1871-1988 monsoon rainfall data, Subbaramayya and Naidu (1992)

A long-lived qubit is usually well-isolated from all other systems and the environments, and so is not easy to couple with measurement apparatus. It is sometimes difficult to implement reliable projective measurements on such a qubit. One potential solution is spin amplification with many ancillary qubits. Here, we propose a spin amplification technique, where the ancillary qubits state change depending on the state of the target qubit. The technique works even in the presence of inhomogeneous broadening. We show that fast and accurate amplification is possible even if the coupling and frequency of the ancillary qubits is inhomogeneous. Since our scheme is robust against realistic imperfections, this could provide a new mechanism for reading out a single spin that could not have been measured using the previous approaches.
Making visible relativistic covariance in graphene and $\alpha$-(BEDT-TTF)$_2$I$_3$

Massless Dirac fermions occur as low-energy modes in several quasi-two-dimensional condensed matter systems such as graphene, the surface of bulk topological insulators, and in layered organic semiconductors. When the rotational symmetry in such systems is reduced either by an in-plane electric field or an intrinsic tilt of the Dirac cones, the allowed dipolar optical transitions evolve from a few selected transitions into a wide fan of interband transitions. We show that the Lorentz covariance of the low-energy carriers allows for a concise analysis of the emerging magneto-optical properties. We predict that infrared absorption spectra yield quantitative information on the tilted Dirac cone structure in organic compounds such as $\alpha$-(BEDT-TTF)$_2$I$_3$.
Radio immunotherapy a promising weapon to consider in the fight against NSCLC

Median progression-free survival was 10.3 months (95% CI 6.7 to not reached) in the pembrolizumab group versus 6.0 months (95% CI, 4.2 to 6.2) in the control group (HR 0.50; 95% CI, 0.37 to 0.68; P<0.001). Results for overall survival are not mature yet, but the estimated rate of overall survival at 6 months also favored pembrolizumab. Previous studies [4,5] reported the benefit of immunotherapy in patients who progressed after a first line of chemotherapy. Although promising results are being reported, the response rate of immunotherapy is still sub-optimal [4-6], this could be explained by underlying mechanisms that are currently under study.
Displacement Mapping on the GPU — State of the Art

This paper reviews the latest developments of displacement mapping algorithms implemented on the vertex, geometry, and fragment shaders of graphics cards. Displacement mapping algorithms are classified as per‐vertex and per‐pixel methods. Per‐pixel approaches are further categorized as safe algorithms that aim at correct solutions in all cases, to unsafe techniques that may fail in extreme cases but are usually much faster than safe algorithms, and to combined methods that exploit the robustness of safe and the speed of unsafe techniques. We discuss the possible roles of vertex, geometry and fragment shaders to implement these algorithms. Then the particular GPU‐based bump, parallax, relief, sphere, horizon mapping, cone stepping, local ray tracing, pyramidal and view‐dependent displacement mapping methods, as well as their numerous variations are reviewed providing also implementation details of the shader programs. We present these methods using uniform notations and also point out when different authors called similar concepts differently. In addition to basic displacement mapping, self‐shadowing and silhouette processing are also reviewed. Based on our experiences gained having reimplemented these methods, their performance and quality are compared, and the advantages and disadvantages are fairly presented.
The Perceived Value And Impact Of Social Characteristics When Managing Projects

A qualitative analysis of the perceived value and impact of social characteristics in managing projects is presented. The analysis is a result of conducting a survey of Organizational Dynamics Graduate Students at the University of Pennsylvania with a Projects, Programs, and Portfolios Concentration. In today’s global world projects are an integral component of doing business in a dynamically changing, uncertain, and complex marketplace. An organization’s ability to adapt may depend on its ability to communicate and integrate cross-functionally. Much of what has been written about project management addresses knowledge areas and processes. Many organizations use tools, methodologies, and processes that add rigor to the project life cycle. As the discipline grows, the human side of project management must be considered. There is increasing global awareness that social characteristics are an important component to managing projects. Art and science will converge to create a new socially aware manager. Project managers are positioned to be change agents as their organizations experience a metamorphic paradigm shift.

M ay 2 01 8 Emergence of Space and Entropy Maximization

The accelerated expansion of the universe can be interpreted as a quest for satisfying holographic equipartition. It can be expressed by a simple law, ∆V = ∆t (Nsurf −Nbulk) which leads to the standard Friedmann equation. This novel idea suggested by Padmanabhan in the context of general relativity has been generalized by Sheykhi to Gauss Bonnet and Lovelock gravity for a universe with any spatial curvature. We have proved the consistency of this generalized holographic equipartition law with the maximum entropy principle. In particular, when the degrees of freedom in the bulk (Nbulk) becomes equal to the degrees of freedom on the boundary surface (Nsurf ), the universe attains a state of maximum entropy. Thus, the validity of the holographic equipartition law ensures the validity of the maximum entropy principle.

On Loan Sales, Loan Contracting, and Lending Relationships

This paper examines the secondary market for loan sales and, in particular, loan contract design as a mechanism to resolve informational issues in loan sales and associated costs and benefits. Using loan-level data, we find that sold loans contain additional covenants and more restrictive net worth covenants, particularly when agency and informational problems are more severe. Why do borrowers agree to incur the additional costs associated with loan sales? Our evidence suggests that these borrowers benefit through increased private debt availability. Further, loan sales go hand in hand with more durable lending relationships, suggesting that risk management aids continued relationship lending. The Author 2008.

Jansen et al. A Bayesian networks approach for predicting protein-protein interactions from genomic data Materials and methods Datasets Genomic features for computation of the PIP mRNA expression We use publicly available expression data, in particular, a time course of expression fluctuations during the yeast cell cycle and the Rosetta compendium, consisting of the expression profiles of 300 deletion mutants and cells under chemical treatments (S1, S2). This data can be used for the prediction of protein-protein interaction because proteins in the same complex are often co-expressed (S3-S6). We computed the Pearson correlation for each protein pair for both the Rosetta and cell cycle datasets. For predicting protein-protein interactions, the Rosetta correlation and the cell cycle correlation represent strongly correlated evidence (see discussion below). We circumvented this problem by computing the first principal component of the vector of the two correlations. Then we used this first principal component as one independent source of evidence for the protein-protein interaction prediction. This first principal component is a stronger predictor of protein-protein interactions than either of the two expression correlation datasets by themselves. We divided this first principal component of expression correlations into 19 bins. For each bin we assessed its overlap with the gold-standard (table S1).

Generalizing a classical theorem of Carlson and Toledo, we prove that any Zariski dense isometric action of a Kähler group on the real hyperbolic space of dimension at least 3 factors through a homomorphism onto a cocompact discrete subgroup of PSL2(R). We also study actions of Kähler groups on infinite dimensional real hyperbolic spaces, describe some exotic actions of PSL2(R) on these spaces, and give an application to the study of the Cremona group.
First steps to a constructor theory of cognition

This article applies the conceptual framework of constructor theory of information to cognition theory. The main result of this work is that cognition theory, in specific situations concerning for example the conjunction fallacy heuristic, requires the use of superinformation media, just as quantum theory. This result entails that quantum and cognition theories can be considered as elements of a general class of superinformation-based subsidiary theories.
The Consequences of Foster Care Versus Institutional Care in Early Childhood on Adolescent Cardiometabolic and Immune Markers: Results From a Randomized Controlled Trial

Supplemental digital content is available in the text. ABSTRACT Objective Children exposed to institutional rearing often exhibit problems across a broad array of developmental domains. We compared the consequences of long-term, high-quality foster care versus standard institution-based care, which began in early childhood on cardiometabolic and immune markers assessed at the time of adolescence. Methods The Bucharest Early Intervention Project is a longitudinal investigation of children institutionalized during early childhood (ages 6 to 30 months at baseline) who were subsequently randomized to either high-quality foster care or continued institutional care. At the age of 16 years, 127 respondents participated in a biomarker collection protocol, including 44 institutionalized children randomly assigned to receive care as usual, 41 institutionalized children randomized to be removed from institutional care and placed in high-quality foster care in infancy, and a control group of 42 demographically matched children raised in biological families. Outcomes included body mass index (BMI), systolic and diastolic blood pressure, C-reactive protein, interleukin (IL)-6, IL-8, IL-10, tumor necrosis factor α, glycosylated hemoglobin A1c, and Epstein-Barr virus antibody titers. Results Early institutional rearing was not associated with differences in cardiometabolic or immune markers. Randomization to foster care and age of placement into foster care were also unrelated to these markers, with the exception of BMI z-score, where children assigned to care as usual had lower BMI z-scores relative to children assigned to foster care (−0.23 versus 0.08, p = .06), and older age at placement was associated with lower BMI (β = −0.07, p = .03). Conclusions The impact of institutional rearing on measures of cardiometabolic health and immune system functioning is either absent or not evident until later in development. These findings provide new insights into the biological embedding of adversity and how it varies developmentally and across regulatory systems and adversity type.

Correlations of carotid intima-media thickness with endothelial function and atherosclerosis degree in patients with type 2 diabetes mellitus.

OBJECTIVE To investigate the correlation of carotid intima-media thickness (IMT) with endothelial function and atherosclerosis degree in patients with type 2 diabetes mellitus. METHODS A total of 80 patients with type 2 diabetes mellitus admitted and treated in our hospital from January 2017 to January 2018 were selected and randomly divided into two groups (n = 40). Patients who were definitely diagnosed with type 2 diabetes mellitus were selected as observation group, and individuals who received health examination and were excluded from type 2 diabetes mellitus were enrolled as control group. The diagnosed proportions of carotid plaque, Crouse scores, endothelial-dependent flow-mediated vasodilation (FMD) function and nitroglycerin-mediated dilation (NMD) function of the brachial arteries in the two groups were compared. The indexes related to vascular endothelial functions [vascular endothelial growth factor (VEGF), endothelin-1 (ET-1) and nitric oxide (NO) levels] in the two groups were detected. The correlations of Crouse score with brachial arterial FMD value, VEGF level, ET-1 level and NO level in observation group were analyzed. RESULTS The diagnosed proportion of carotid plaque in observation group was significantly higher than that in control group (P < 0.05), and the Crouse score in observation group was higher than that in control group (P < 0.05). The brachial arterial FMD value in observation group was remarkably lower than that in control group (P < 0.05). Compared with control group, VEGF and ET-1 levels were significantly reduced in observation group (P < 0.05), with the statistical increase of NO level (P < 0.05). In observation group, the Crouse score was negatively correlated with the brachial arterial FMD value, VEGF level and ET-1 level, whereas positively correlated with the NO level (P < 0.05). CONCLUSION Our data show that the carotid IMT is increased significantly among patients with type 2 diabetes mellitus, and the vascular endothelial function is impaired. Moreover, after the occurrence of atherosclerosis, we found the carotid IMT is negatively correlated with endothelial-dependent FMD, as well as levels of VEGF and ET-1, whereas shows positive correlation with the vasodilative factor NO.
Changes in Use of Postacute Care Associated With Accountable Care Organizations in Hip Fracture, Stroke, and Pneumonia Hospitalized Cohorts

Objective: To examine changes in more and less discretionary condition-specific postacute care use (skilled nursing, inpatient rehabilitation, home health) associated with Medicare accountable care organization (ACO) implementation. Data Sources: 2009–2014 Medicare fee-for-service claims. Study Design: Difference-in-difference methodology comparing postacute outcomes after hospitalization for hip fracture and stroke (where rehabilitation is fundamental to the episode of care) to pneumonia, (where it is more discretionary) for beneficiaries attributed to ACO and non-ACO providers. Principal Findings: Across all 3 cohorts, in the baseline period ACO patients were more likely to receive Medicare-paid postacute care and had higher episode spending. In hip fracture patients where rehabilitation is standard of care, ACO implementation was associated with 6%–8% increases in probability of admission to a skilled nursing facility or inpatient rehabilitation (compared with home without care), and a slight reduction in readmissions. In a clinical condition where rehabilitation is more discretionary, pneumonia, ACO implementation was not associated with changes in postacute location, but episodic spending decreased 2%–3%. Spending decreases were concentrated in the least complex patients. Across all cohorts, the length of stay in skilled nursing facilities decreased with ACO implementation. Conclusions: ACOs decreased spending on postacute care by decreasing use of discretionary services. ACO implementation was associated with reduced length of stay in skilled nursing facilities, while hip fracture patients used institutional postacute settings at higher rates. Among pneumonia patients, we observed decreases in spending, readmission days, and mortality associated with ACO implementation.
