Suppression of Qubit Crosstalk in a Tunable Coupling Superconducting Circuit

Parasitic crosstalk in superconducting quantum devices is a leading limitation for quantum gates. We demonstrate the suppression of static ZZ crosstalk in a two-qubit, two-coupler superconducting circuit, where the frequency of a tunable coupler can be adjusted such that the ZZ interaction from each coupler destructively interfere. We verify the crosstalk elimination with simultaneous randomized benchmarking, and use a parametrically activated iSWAP interaction to achieve a Bell state preparation fidelity of 98.5% and a $\sqrt{\textrm{iSWAP}}$ gate fidelity of 94.8% obtained via quantum process tomography.
Jealousy mediates the relationship between attractiveness comparison and females' indirect aggression

Indirect aggression is considered an evolutionarily adaptive mechanism that can improve female mating success. It has been hypothesized that indirect aggression toward romantic partners and peers is used more frequently by females who make appearance-based comparisons and that these relationships are mediated by jealousy. Females (N = 528) currently in romantic relationships were surveyed. Results confirmed females who made more frequent appearance comparisons aggressed more often toward partners and peers. Low-comparing females reported being more frequent targets of peer indirect aggression. Jealousy partially mediated the relationships between making frequent attractiveness comparisons and indirect aggression. Results are discussed as effort allocated toward deterring partner defection and fending off rivals, and the role of emotion as a motivational influence for aggression. Throughout human evolutionary history both males and females have had to contend with threats to their reproductive success. Owing to concealed ovulation and the internal fertilization process of reproduction, a female’s infidelity translates into paternity uncertainty for males (Buss, 2004). Although females are not faced with this particular dilemma,
Escort tug design alternatives and a comparison of their hydrodynamic performance. Discussion

Escort tugs can generate forces for steering and braking a disabled tanker which are greater than the bollard pull delivered by the propulsion system. This is achieved by using a hull shape and appendages that can generate very high forces at yaw angles up to 45 degrees, combined with an azimuthing propulsion system to resist the resulting yaw moments generated from the hydrodynamic forces. This mode of operation is known as indirect steering or braking and results in a high degree of interaction between the flow around the hull and the flow due to the propellers. Model experiments are the most promising approach for studying these complex interactions, but there is very little model data published on the subject. Successful escort tug designs have resulted from different combinations of appendages and propulsion systems but there is no published data that compares the predicted performance of different alternatives. This paper attempts to fill this gap by presenting the hydrodynamic performance of three different combinations of hull shape, appendages and propulsion system, and uses the results to discuss the effectiveness of alternative design solutions for escort tugs with specified steering force requirements.
The Incidence of Signs and Symptoms of Temporomandibular Disorders Following Third Molar Surgery

Third molar surgery, a common dental procedure in Dental Faculty University Malaya, is known to pose many possible complications, one of which is temporomandibular disorder (TMD); a chronic pain concerning the joint apparatus, masticatory musculature and the associated muscle of head and neck region. This research aims (i) to examine the signs and symptoms of TMD following third molar surgery (ii) to study the surgical components of third molar surgery that contribute to the development of TMD (iii) to compare incidence of TMD between operative and non-operative group six months after third molar surgery. A descriptive longitudinal cohort study was conducted by recruiting twenty-two patients as subjects of an operative group, and twenty patients as subjects of a non-operative group. The operative group were examined at baseline, one week, one month, three months and six months after surgery. Each patient underwent a series of Diagnostic Criteria of TMD DC/TMD examination and history questionnaire. In the operative group, we found (i) increased incidence of trismus (92%), myofascial pain (69%) and clicking (77%) of the patient group at one week review (ii) two new incidences of signs and symptoms of TMD at final review (iii) no significant relationship between operator qualification to development of TMD (iv) no association between degree of impaction to development of TMD (v) no relationship between duration of procedures to development of TMD (vi) there is a significant difference in signs and symptoms of TMD between operative group and control group (p<0.005).
Estimating NH 3 emissions from agricultural fertilizer application in China using the bi-directional CMAQ model coupled to an agro-ecosystem model

Abstract. Atmospheric ammonia (NH3) plays an important role in atmospheric aerosol chemistry. China is one of the largest NH3 emitting countries with the majority of NH3 emissions coming from agricultural practices, such as fertilizer application and livestock production. The current NH3 emission estimates in China are mainly based on pre-defined emission factors that lack temporal or spatial details, which are needed to accurately predict NH3 emissions. This study provides the first online estimate of NH3 emissions from agricultural fertilizer application in China, using an agricultural fertilizer modeling system which couples a regional air quality model (the Community Multi-scale Air Quality model, or CMAQ) and an agro-ecosystem model (the Environmental Policy Integrated Climate model, or EPIC). This method improves the spatial and temporal resolution of NH3 emissions from this sector. We combined the cropland area data of 14 crops from 2710 counties with the Moderate Resolution Imaging Spectroradiometer (MODIS) land use data to determine the crop distribution. The fertilizer application rates and methods for different crops were collected at provincial or agricultural region levels. The EPIC outputs of daily fertilizer application and soil characteristics were input into the CMAQ model and the hourly NH3 emissions were calculated online with CMAQ running. The estimated agricultural fertilizer NH3 emissions in this study were approximately 3 Tg in 2011. The regions with the highest modeled emission rates are located in the North China Plain. Seasonally, peak ammonia emissions occur from April to July. Compared with previous researches, this study considers an increased number of influencing factors, such as meteorological fields, soil and fertilizer application, and provides improved NH3 emissions with higher spatial and temporal resolution.
State Fragility, Rent Seeking and Lobbying: Evidence from African Data

This paper assesses the determinants of state fragility in sub-Saharan Africa using hitherto unexplored variables in the literature. The previously missing dimension of nation building is integrated and the hypothesis of state fragility being a function of rent seeking and/or lobbying by de facto power holders is tested. The resulting interesting finding is that, political interference, rent seeking and lobbying increase the probability of state fragility by mitigating the effectiveness of governance capacity. This relationship (after controlling for a range of economic, institutional and demographic factors) is consistent with a plethora of models and specifications. The validity of the hypothesis is confirmed in a scenario of extreme state fragility. Moreover, the interaction between political interferences and revolutions mitigate the probability of state fragility while the interaction between natural resources and political interferences breeds the probability of extreme state fragility. As a policy implication, there is a ‘sub-Saharan African specificity’ in ‘nation building’ and prevention of conflicts. Blanket fragility oriented policies will be misplaced unless they are contingent on the degree of fragility, since ‘fragile’ and ‘extreme fragile’ countries respond differently to economic, institutional and demographic characteristics of state fragility.
Numerical overcooling in shocks.

We present a study of cooling in radiative shocks simulated with smoothed particle hydrodynamics and adaptive mesh refinement codes. We obtain a similarity solution for a shock-tube problem in the presence of radiative cooling, and test how well the solution is reproduced in GADGET and FLASH. Shock broadening governed by the details of the numerical scheme (artificial viscosity or Riemann solvers) leads to potentially significant overcooling in both codes. We interpret our findings in terms of a resolution criterion, and apply it to realistic simulations of cosmological accretion shocks on to galaxy haloes, cold accretion and thermal feedback from supernovae or active galactic nuclei (AGN). To avoid numerical overcooling of accretion shocks on to haloes that should develop a hot corona a particle or cell mass resolution of 106 M⊙ is required, which is within reach of current state-of-the-art simulations. At this mass resolution, thermal feedback in the interstellar medium of a galaxy requires temperatures of supernova- or AGN-driven bubbles to be in excess of 107 K at densities of nH= 1.0 cm−3, in order to avoid spurious suppression of the feedback by numerical overcooling.
Study of urgent visits to commercial rabbit farms in Spain and Portugal during 1997-2007

This is a report on work carried out on 4307 visits to 868 commercial farms with domestic rabbits in Spain and Portugal from January 1997 to December 2007. Of the total visits, 2237 (52%) were emergencies on 660 farms. The median size of the farms ranged between 450 does in 1997 and 750 in 2007. This retrospective study measures the clinical disease occurrence using the Monthly Risk of urgent visits (MR), i.e. the percentage of visits made as a result of each clinical disease in comparison with the total number of urgent visits made each month. The main reasons for the emergencies were mucoid enteropathy (similar to Epizootic Rabbit Enteropathy), with a MR: 25.0%, enteritis-diarrhoea (24.1%), myxomatosis, (11.1%), reproductive troubles (8.6%), respiratory diseases (7.2%) and staphylococcosis (4.2%). Fifty-four percent of the urgent visits were due to diseases of the digestive system. Mucoid enteropathy was still one of the main diseases faced by the commercial rabbit industry during the study period. No significant yearly or monthly variations were observed in the analysis of the MR. A seasonal effect was only found in respiratory diseases during the summer (MR: 11.06±0.01) and myxomatosis in autumn (MR: 14.60±0.02), in comparison with spring (MR: 7.44±0.02). It is therefore concluded that farms should be permanently protected as they might be affected by any of these diseases at any time during the year.
Age-dependence of cultured pearl grade and colour in the black-lipped pearl oyster Pinctada margaritifera

Pinctada margaritifera is an economically important marine bivalve species for cultured pearl production in French Polynesian aquaculture. In order to evaluate the influence of donor oyster age on pearl quality traits, experiments were conducted over 6 years using both grafts and surgreffe operations. At harvest, 6 pearl quality traits were recorded and compared: surface defects, luster, grade, darkness level, and visual color. Analyzing the quality traits of pearls harvested in the initial graft process and those of pearls obtained from surgreffe experiments allowed a comparison of the influence of pearl sac cells originating from the initial mantle graft, which aged together with their recipient oysters. The results demonstrated a significant decrease between these successive grafts in luster, grade (A-B-C,) darkness level, and green color – traits that are of major importance in the pearl market. The duplicated graft experiment allowed the comparison of donor oyster families at 2 and 5 years old, where a mantle graft was inserted into recipient oysters aged 2.5 years old. The results showed the same tendencies to a lesser extent, with 1) an improved pearl grade, predominantly through a most important rate of 0 surface defect category, and 2) a green / grey ratio in favor of the younger donor. A comparison between the graft-surgreffe and the duplicated graft experiments also highlighted: 1) the indirect role played by the younger recipient oysters, which must be optimized for optimal pearl quality realization, and 2) the complex interplay between donor and recipient oysters.
The effect of a Holocene climatic optimum on the evolution of the Greenland ice sheet during the last 10 kyr

ABSTRACT The Holocene climatic optimum was a period 8–5 kyr ago when annual mean surface temperatures in Greenland were 2–3°C warmer than present-day values. However, this warming left little imprint on commonly used temperature proxies often used to derive the climate forcing for simulations of the past evolution of the Greenland ice sheet. In this study, we investigate the evolution of the Greenland ice sheet through the Holocene when forced by different proxy-derived temperature histories from ice core records, focusing on the effect of sustained higher surface temperatures during the early Holocene. We find that the ice sheet retreats to a minimum volume of ~0.15–1.2 m sea-level equivalent smaller than present in the early or mid-Holocene when forcing an ice-sheet model with temperature reconstructions that contain a climatic optimum, and that the ice sheet has continued to recover from this minimum up to present day. Reconstructions without a warm climatic optimum in the early Holocene result in smaller ice losses continuing throughout the last 10 kyr. For all the simulated ice-sheet histories, the ice sheet is approaching a steady state at the end of the 20th century.
Fuel Consumption Sensitivity of Conventional and Hybrid Electric Light-Duty Gasoline Vehicles to Driving Style

Aggressive driving is an important topic for many reasons, one of which is higher energy used per unit distance traveled, potentially accompanied by an elevated production of greenhouse gases and other pollutants. Examining a large data set of self-reported fuel economy (FE) values revealed that the dispersion of FE values is quite large and is larger for hybrid electric vehicles (HEVs) than for conventional gasoline vehicles. This occurred despite the fact that the city and highway FE ratings for HEVs are generally much closer in value than for conventional gasoline vehicles. A study was undertaken to better understand this and better quantify the effects of aggressive driving, including reviewing past aggressive driving studies, developing and exercising a new vehicle energy model, and conducting a related experimental investigation. The vehicle energy model focused on the limitations of regenerative braking in combination with varying levels of driving-style aggressiveness to show that this could account for greater FE variation in an HEV compared to a similar conventional vehicle. A closely matched pair of gasoline-fueled sedans, one an HEV and the other having a conventional powertrain, was chosen for both modeling and chassis dynamometer experimental comparisons. Results indicate that the regenerative braking limitations could be a main contributor to the greater HEV FE variation under the range of drive cycles considered. The complete body of results gives insight into the range of fuel use penalties that results from aggressive driving and why the variation can be larger on a percent basis for an HEV compared to a similar conventional vehicle, while the absolute fuel use penalty for aggressive driving is generally larger for conventional vehicles than HEVs.

Translocable Glucose Transporters in the Brain

The discovery of the brain expression of the translocable glucose transporters, GLUT4 then GLUT8, led to the question of their putative role in the central nervous system, particularly in relation to insulin effect. The anatomical, cellular, and subcellular localization of these transporters has been described in detail. It has been shown that, as in peripheral tissues, these transporters are localized both in an intracellular pool and at the plasma membrane. This is coherent with a translocation phenomenon, but the data reporting the effect of insulin on that property of GLUT4 and GLUT8 remains very controversial. Glucose and insulin have been shown to modulate GLUT4 expression. Based on their anatomical features, different hypotheses have been proposed. Because of the colocalization with the insulin receptors, insulin might regulate glucose uptake in specific brain areas. A role in nutrient sensing has also been proposed, since both insulin and GLUT4 are expressed in gluco-excited neurons of the hypothalamus. Some studies suggest a role for GLUT8 in the endoplasmic reticulum stress. Whereas much has been learned about their cellular features in the central nervous system, many questions remain unanswered concerning their physiological functions. Gene knockout strategy specifically in the brain and even more in specific nuclei or type of cells should provide new clues to the physiological role of both transporters in the central nervous system.
Integration of Sovereign Bonds Markets: Time Variation and Maturity Effects

We examine time varying integration of developed (DM) and emerging (EM) market government bonds. Although we find an upward trend for most countries and maturity bands, we do observe reversals and negative trends among both DMs and EMs and for some maturities during the financial crisis. We examine potential factors that could explain the integration of the long vs. the short maturity bond segments and show that enhanced institutional quality, higher credit quality and better future investment opportunities would jointly contribute to a higher integration of the long vs. the short maturity bonds by about 15%.
Component Analysis of Isoflavonoids in Pueraria montana and Pueraria lobata by High Performance Liquid Chromatography

Radix of Pueraria spp. is a popular traditional Chinese medicine. There are two major species of Pueraria in Taiwan, i.e., Pueraria montana and Pueraria lobata. The major constituents of Puerariae radix were isoflavonoids, which include puerarin, daidzin, genistin, genistein, daidzein and daidzein-4', 7- diglucoside. This study developed simultaneous analysis of multi-component HPLC method to determine the six components of isoflavonoids in root, vine, leaf, and petiole parts of P. montana and P. lobata for establishing a standard quality control of Pueraria spp. Results showed that the highest level of isoflavonoids was observed in the root and vine of P. lobata, and the daidzein-4', 7-diglucoside was only found in root and vine of P. lobata. Levels of isoflavones existed among species, as well as organs, were significantly different.
Natural kalsilite, KAlSiO4, with P31c symmetry: Crystal structure and twinning

Abstract A new KAlSiO4 polymorph was found in a granulite facies gneiss from the Punalur district, southern India. The structure was solved and refined on a twinned crystal to an R index value of 1.98% for 265 independent reflections. Metamorphic kalsilite is trigonal, space group P31c with a 5.157 (1) Å , c = 8.706 (3) Å , V = 200.52 (9) Å3, Z = 2. The overall diffraction symmetry 6/mmm exhibited from all the crystals examined arises from a {0001} twinning, related to a mistake in the ordered Al-Si-Al-Si sequence along the c axis. The crystal structure is a stuffed derivate of tridymite, and is characterized by sixmembered tetrahedral rings with ditrigonal shape. Individual layers of this structure are the same as those of P63 kalsilite, but are stacked along the c axis in an eclipsed manner rather than in the staggered manner of the P63 structure.
Cholesterol templated polymers : are they really specific binding materials?

The technique of molecular imprinting creates template specific and selective polymer products with a large assortment of applications. For example, molecularly imprinted polymers (MIPs) may pose as a means to separate undesirable components, such as endocrine disruptors, from the environment. Taking advantage of β-cyclodextrin's abililty to form inclusion complexes with a number of guests has led scientists to use them as scaffolds in the synthesis of MIPs. Komiyana's approach of molecularly imprinting cholesterol with β-cyclodextrin was used as a starting point to apply MIPs as potential tools for trapping endocrine disruptors. This study presents results on the re-binding of cholesterol to a cholesterol-templated MIP and to a non-MIP (NMIP), as well as the binding of a series of structurally unrelated compounds to the cholesterol-templated MIP and NMIP. The results consistently show that cholesterol-templated MIPs synthesized using Komiyama's method lack specificity and selectivity for their template. This calls into question their efficacy as a tool for trapping endocrine disruptors.
Optimal strokes for driftless swimmers: A general geometric approach

Swimming consists by definition in propelling through a fluid by means of bodily movements. Thus, from a mathematical point of view, swimming turns into a control problem for which the controls are the deformations of the swimmer. The aim of this paper is to present a unified geometric approach for the optimization of the body deformations of so-called driftless swimmers. The class of driftless swimmers includes, among other, swimmers in a 3D Stokes flow (case of micro-swimmers in viscous fluids) or swimmers in a 2D or 3D potential flow. A general framework is introduced, allowing the complete analysis of five usual nonlinear optimization problems to be carried out. The results are illustrated with examples coming from the literature and with an in-depth study of a swimmer in a 2D potential flow. Numerical tests are also provided.
