Stabilized Lithium–Sulfur Batteries by Covalently Binding Sulfur onto the Thiol‐Terminated Polymeric Matrices

Published: September 2017

AbstractDespite the low competitive cost and high theoretical capacity of lithium–sulfur battery, its practical application is severely hindered by fast capacity fading and limited capacity retention mainly caused by the polysulfide dissolution problem. Here, this paper reports a new strategy of using thiol‐terminated polymeric matrices to prevent polysulfide dissolution, which exhibits an initial capacity of 829.1 mAh g−1, and the exceptionally stable capacity retention of ≈84% at 1 C after 200 cycles, and excellent cycling stability with a low mean decay rate of 0.048% after 600 cycles. Significantly, in situ UV/vis spectroscopy analysis of the electrolyte upon battery cycling is performed to verify the function of preventing polysulfide dissolution by means of strongly anchoring discharge products of lithium sulphides. Moreover, density functional theory calculations reveal that the breakage of the linear sulfur chains results in the less soluble short‐chain polysulfides due to the formation of the covalently crosslinked discharge products, which avoids the production of soluble long‐chain polysulfide and minimizes the shuttle effect. These results exhibit an alternative for the stabilization of the electrochemical performance of lithium–sulfur batteries.

Published: September 2017

AbstractNowadays, photodynamic therapy (PDT) is under the research spotlight as an appealing modality for various malignant tumors. Compared with conventional PDT treatment activated by ultraviolet or visible light, near infrared (NIR) light‐triggered PDT possessing deeper penetration to lesion area and lower photodamage to normal tissue holds great potential for in vivo deep‐seated tumor. In this review, recent research progress related to the exploration of NIR light responsive PDT nanosystems is summarized. To address current obstacles of PDT treatment and facilitate the effective utilization, several innovative strategies are developed and introduced into PDT nanosystems, including the conjugation with targeted moieties, O2 self‐sufficient PDT, dual photosensitizers (PSs)‐loaded PDT nanoplatform, and PDT‐involved synergistic therapy. Finally, the potential challenges as well as the prospective for further development are also discussed.

Published: September 2017

AbstractPressure sensing is a crucial function for flexible and wearable electronics, such as artificial skin and health monitoring. Recent progress in material and device structure of pressure sensors has brought breakthroughs in flexibility, self‐healing, and sensitivity. However, the fabrication process of many pressure sensors is too complicated and difficult to integrate with traditional silicon‐based Micro‐Electro‐Mechanical System(MEMS). Here, this study demonstrates a scalable and integratable contact resistance‐based pressure sensor based on a carbon nanotube conductive network and a photoresist insulation layer. The pressure sensors have high sensitivity (95.5 kPa−1), low sensing threshold (16 Pa), fast response speed (<16 ms), and zero power consumption when without loading pressure. The sensitivity, sensing threshold, and dynamic range are all tunable by conveniently modifying the hole diameter and thickness of insulation layer.
Bend‐bend‐twist vibrations of a wind turbine blade
Authors: Acar Gizem D. , Feeny Brian F. 
Published: September 2017

AbstractDynamics of a wind turbine blade under bend‐bend‐twist coupled vibrations is investigated. The potential and kinetic energy expressions for a straight nonuniform blade are written in terms of beam parameters. Then, the energies are expressed in terms of modal coordinates by using the assumed mode method, and the equations of motion are found by applying Lagrange's formula. The bend‐bend‐twist equations are coupled with each other and have stiffness variations due to centrifugal effects and gravitational parametric terms, which vary cyclicly with the hub angle. To determine the natural frequencies and mode shapes of the system, a modal analysis is applied on the linearized coupled equations of constant angle snapshots of a blade with effects of constant speed rotation. Lower modes of the coupled bend‐bend‐twist model are dominantly in‐plane or out‐of‐plane modes. To investigate the parametric effects, several blade models are analyzed at different angular positions. The stiffness terms involving centrifugal and gravitational effects can be significant for long blades. To further see the effect of blade length on relative parametric stiffness change, the blade models are scaled in size and analyzed at constant rotational speeds, at horizontal and vertical orientations. These studies show that the parametric stiffness effects should be taken into account when designing long blades.
A statistical mechanical phase transition to turbulence in a model shear flow
Authors: Goldenfeld Nigel 
Published: September 2017

It is becoming increasingly clear that the strong spatial and temporal fluctuations observed in a narrow Reynolds number regime around the laminar–turbulent transition in shear flows can best be understood using the concepts and techniques from a seemingly unrelated discipline – statistical mechanics. During the last few years, a consensus has begun to emerge that these phenomena reflect an underlying non-equilibrium phase transition exhibited by a model of interacting particles on a crystalline lattice, directed percolation, that seems very far from fluid mechanics. Now, Chantry et al. (J. Fluid Mech., vol. 824, 2017, R1) have developed a truncated-mode computation of a model shear flow, capable of simulating systems far larger and longer than any previous study and have for the first time generated enough statistical data that a high-precision test of theory is feasible. The results broadly confirm the theory, extending the class of flows for which the directed percolation scenario holds and removing any remaining doubts that non-equilibrium statistical mechanical critical phenomena can be exhibited by the Navier–Stokes equations.

AbstractSurveys report that 25–57 % of cats are overweight or obese. The most evinced cause is neutering. Weight loss often fails; thus, new strategies are needed. Obesity has been associated with altered gut bacterial populations and increases in microbial dietary energy extraction, body weight and adiposity. This study aimed to determine whether alterations in intestinal bacteria were associated with obesity, energy restriction and neutering by characterising faecal microbiota using 16S rRNA gene sequencing in eight lean intact, eight lean neutered and eight obese neutered cats before and after 6 weeks of energy restriction. Lean neutered cats had a bacterial profile similar to obese rodents and humans, with a greater abundance (P<0·05) of Firmicutes and lower abundance (P<0·05) of Bacteroidetes compared with the other groups. The greater abundance of Firmicutes in lean neutered cats was due to a bloom in Peptostreptococcaceae. Obese cats had an 18 % reduction in fat mass after energy restriction (P<0·05). Energy reduction was concurrent with significant shifts in two low-abundance bacterial genera and trends in four additional genera. The greatest change was a reduction in the Firmicutes genus,Sarcina, from 4·54 to 0·65 % abundance after energy restriction. The short duration of energy restriction may explain why few bacterial changes were observed in the obese cats. Additional work is needed to understand how neutering, obesity and weight loss are related to changes in feline microbiota and how these microbial shifts affect host physiology.

Published: September 2017

AbstractAphelinus mali(Haldeman) is an effective natural enemy of woolly apple aphid (WAA),Eriosoma lanigerum(Hausmann). Previous studies have found that, with WAA from Shandong Province (Qingdao) as the host, there are significant differences in various biological characteristics between a Shandong clade and Liaoning clade ofA. mali. The ability of the Shandong clade to control this aphid was significantly higher than that of the Liaoning clade in Shandong Province. In order to determine whether differences were caused by better adaptation of the Shandong parasitoid clade to the population of the host in that province or if it represents a more general fitness of this clade to control the host regardless of location, we compared the same parasitoid clades with hosts from Hebei Province. We found no significant differences in the developmental threshold temperature, effective accumulated temperature, fecundity, longevity, and oviposition period of the two clades, but the duration of host searching of the Shandong clade was significantly longer than that of the Liaoning clade. The instantaneous attack rate, the control ability (a/Th), the search parameter (Q) of the Shandong clade (0.0946, 0.543, 0.0725) ofA. maliwere higher than that of the Liaoning clade (0.0713, 0.382, 0.0381), and therefore, with WAA from Hebei Province as the host, the host adaptability of the Shandong clade ofA. maliwas not worse than that of the Liaoning clade, while the pest control ability of the Shandong clade was still greater than that of the Liaoning clade.
Written and Oral in Islamic Law: Documentary Evidence and Non-Muslims in Moroccan Shari‘a Courts
Authors: Marglin Jessica M. 
Published: September 2017

AbstractThis article begins from the premise that the margins can shine light on the center, and uses the experience of Jews (thought of as marginal in the Islamic world) in Moroccan courts (similarly thought of as marginal in Islamic history) to tell a new story about orality and writing in Islamic law. Using archival evidence from nineteenth-century Morocco, I argue that, contrary to the prevailing historiography, written evidence was central to procedure in Moroccan shari‘a courts. Records of nineteenth-century lawsuits between Jews and Muslims show that not only were notarized documents regularly submitted in court, but they could outweigh oral testimony, traditionally thought of as the gold standard of evidence in Islam. The evidentiary practices of Moroccan shari‘a courts are supported by the jurisprudential literature of the Mālikī school of Sunni Islam, the only one prevalent in Morocco. These findings have particular relevance for the experience of non-Muslims in Islamic legal institutions. Scholars have generally assumed that Jews and Christians faced serious restrictions in their ability to present evidence in shari‘a courts, since they could not testify orally against Muslims. However, in Morocco Jews had equal access to notarized documents, and thus stood on a playing field that, theoretically at least, was level with their Muslim neighbors. More broadly, I explore ways in which old assumptions about the relationship of the written to the oral continue to pervade our understanding of Islamic law, and call for an approach that breaks down the dichotomy between writing and orality.
Developing Terra Nullius: Colonialism, Nationalism, and Indigeneity in the Andaman Islands
Authors: Sen Uditi 
Published: September 2017

AbstractThis article explores the legal structures and discursive framings informing the governance of one particular “backward” region of India, the Andaman Islands. I trace the shifting patterns of occupation and development of the islands in the colonial and postcolonial periods, with a focus on the changes wrought by independence in 1947 and the eventual history of planned development there. I demonstrate how intersecting discourses of indigenous savagery/primitivism and the geographical emptiness were repeatedly mobilized in colonial-era surveys and postcolonial policy documents. Postcolonial visions of developing the Andaman Islands ushered in a settler-colonial governmentality, infused with genocidal fantasies of the “dying savage.” Laws professing to protect aboriginal Jarawas actually worked to unilaterally extend Indian sovereignty over the lands and bodies of a community clearly hostile to such incorporation. I question the current exclusion of India from the global geographies of settler-colonialism and argue that the violent and continuing history of indigenous marginalization in the Andaman Islands represents a de facto operation of a logic of terra nullius.
Witnessing the quantumness of a system by observing only its classical features
Authors: Marletto C. , Vedral V. 
Published: September 2017

AbstractA central problem in fundamental physics is to witness the non-classicality of systems whose dynamics is not completely specified. For example, this arises in testing predictions that a macroscopic system, such as a living system, obeys quantum theory. Notoriously, also, it has been claimed that witnessing non-classicality in the gravitational field is practically impossible. Here, we propose a thought experiment that witnesses the non-classicality of a physical system by probing it with a qubit, without having to assume any specific dynamics on the physical system. Remarkably, this experiment does not require any quantum control of the system, involving only measuring a single classical observable on it. That non-classicality of a system can be established indirectly, by coupling it to a qubit, opens up exciting possibilities, for example, that quantum gravitational effects might be witnessed in the lab.
Global warming not so harmful for all plants - response of holomycotrophic orchid species for the future climate change

Published: September 2017

AbstractCurrent and expected changes in global climate are major threat for biological diversity affecting individuals, communities and ecosystems. However, there is no general trend in the plants response to the climate change. The aim of present study was to evaluate impact of the future climate changes on the distribution of holomycotrophic orchid species using ecological niche modeling approach. Three different scenarios of future climate changes were tested to obtain the most comprehensive insight in the possible habitat loss of 16 holomycotrophic orchids. The extinction of Cephalanthera austiniae was predicted in all analyses. The coverage of suitable niches of Pogoniopsis schenckii will decrease to 1–30% of its current extent. The reduction of at least 50% of climatic niche of Erythrorchis cassythoides and Limodorum abortivum will be observed. In turn, the coverage of suitable niches of Hexalectris spicata, Uleiorchis ulaei and Wullschlaegelia calcarata may be even 16–74 times larger than in the present time. The conducted niche modeling and analysis of the similarity of their climatic tolerance showed instead that the future modification of the coverage of their suitable niches will not be unified and the future climate changes may be not so harmful for holomycotrophic orchids as expected.
“TNOs are Cool”: A survey of the trans-Neptunian region

Published: September 2017

Context. Gravitationally bound multiple systems provide an opportunity to estimate the mean bulk density of the objects, whereas this characteristic is not available for single objects. Being a primitive population of the outer solar system, binary and multiple trans-Neptunian objects (TNOs) provide unique information about bulk density and internal structure, improving our understanding of their formation and evolution.
Aims. The goal of this work is to analyse parameters of multiple trans-Neptunian systems, observed with Herschel and Spitzer space telescopes. Particularly, statistical analysis is done for radiometric size and geometric albedo, obtained from photometric observations, and for estimated bulk density.
Methods. We use Monte Carlo simulation to estimate the real size distribution of TNOs. For this purpose, we expand the dataset of diameters by adopting the Minor Planet Center database list with available values of the absolute magnitude therein, and the albedo distribution derived from Herschel radiometric measurements. We use the 2-sample Anderson–Darling non-parametric statistical method for testing whether two samples of diameters, for binary and single TNOs, come from the same distribution. Additionally, we use the Spearman’s coefficient as a measure of rank correlations between parameters. Uncertainties of estimated parameters together with lack of data are taken into account. Conclusions about correlations between parameters are based on statistical hypothesis testing.
Results. We have found that the difference in size distributions of multiple and single TNOs is biased by small objects. The test on correlations between parameters shows that the effective diameter of binary TNOs strongly correlates with heliocentric orbital inclination and with magnitude difference between components of binary system. The correlation between diameter and magnitude difference implies that small and large binaries are formed by different mechanisms. Furthermore, the statistical test indicates, although not significant with the sample size, that a moderately strong correlation exists between diameter and bulk density.

Context. The available set of spin and shape modelled asteroids is strongly biased against slowly rotating targets and those with low lightcurve amplitudes. This is due to the observing selection effects. As a consequence, the current picture of asteroid spin axis distribution, rotation rates, radiometric properties, or aspects related to the object’s internal structure might be affected too.
Aims. To counteract these selection effects, we are running a photometric campaign of a large sample of main belt asteroids omitted in most previous studies. Using least chi-squared fitting we determined synodic rotation periods and verified previous determinations. When a dataset for a given target was sufficiently large and varied, we performed spin and shape modelling with two different methods to compare their performance.
Methods. We used the convex inversion method and the non-convex SAGE algorithm, applied on the same datasets of dense lightcurves. Both methods search for the lowest deviations between observed and modelled lightcurves, though using different approaches. Unlike convex inversion, the SAGE method allows for the existence of valleys and indentations on the shapes based only on lightcurves.
Results. We obtain detailed spin and shape models for the first five targets of our sample: (159) Aemilia, (227) Philosophia, (329) Svea, (478) Tergeste, and (487) Venetia. When compared to stellar occultation chords, our models obtained an absolute size scale and major topographic features of the shape models were also confirmed. When applied to thermophysical modelling (TPM), they provided a very good fit to the infrared data and allowed their size, albedo, and thermal inertia to be determined.
Conclusions. Convex and non-convex shape models provide comparable fits to lightcurves. However, some non-convex models fit notably better to stellar occultation chords and to infrared data in sophisticated thermophysical modelling (TPM). In some cases TPM showed strong preference for one of the spin and shape solutions. Also, we confirmed that slowly rotating asteroids tend to have higher-than-average values of thermal inertia, which might be caused by properties of the surface layers underlying the skin depth.
Challenges in Multivalvular Heart Disease: Indian Scenario
Authors: Ladha Suruchi , Kapoor Poonam 
Published: September 2017

AbstractMultivalvular disease (MVD) is a common scenario with various clinical challenges and limited availability of evidence-based recommendations. The pathophysiology of patients having MVD is dependent on the specific combination of valve lesions. The anesthesiologist should be aware of the echocardiographic pitfalls as many commonly used echocardiographic parameters for the assessment and quantification of valve lesions is validated only in patients with single-valve disease. It is also necessary to take into account the interaction between the different valve lesions while interpreting echocardiography. The management decisions of such patients depend on the assessment of the different valve lesions and their effect on symptoms, pulmonary hypertension, and left ventricular dysfunction. The decision to intervene on multiple valves should take into account both the surgical risk of combined procedures and the advantages of available percutaneous techniques. In this review, we discuss the common clinical scenario, pathophysiology, echocardiographic challenges, and guideline-directed management options in patients with MVD.

AbstractAnesthesia in any abnormal environment, such as high altitude, is a challenge for all anesthesiologists. To have safe anesthesia at that time, the pathophysiological changes in both the unacclimatized and acclimatized patients at high altitude, which include pulmonary hyperventilation, polycythemia, rising pulmonary blood volume, pulmonary hypertension, and increase in diffusion capacity, are to be considered in preanesthetic checkup.
