Tubular catalytic micromotors in transition from unidirectional bubble sequences to more complex bidirectional motion

The generation of oxygen microbubbles in catalytic microtubes has attracted tremendous attention towards the exploration of unidirectional and overloaded bubble ejection regimes, leading to simple and more complex motions of micromotors. While it is widely believed that a bubble's frequency in a unidirectional regime (i.e., a bubble ejected from a single tubular opening) is random, this study shall demonstrate that periodic oxygen bubble frequencies and sequences can be experimentally controlled using various concentrations of hydrogen peroxide fuel and surfactants. When released from a substrate, unidirectional micromotors self-propel in straight, circular, and helical trajectories, leading to a class of well-predictable or simple micromachines. Under overloaded conditions, micromotors generate bubbles at both tubular openings, which influence the trajectories of micromotor motion strongly. A one-dimensional reaction-diffusion equation is formulated to explain the possible mechanisms of mass transport in microtubes and the transition from the unidirectional to the overloaded regime of micromotors.The generation of oxygen microbubbles in catalytic microtubes has attracted tremendous attention towards the exploration of unidirectional and overloaded bubble ejection regimes, leading to simple and more complex motions of micromotors.

Design of Low Power Ka-Band Frequency Doubler in 45-nm CMOS-SOI with 45-dBc Fundamental Rejection at Center Frequency

A frequency doubler operates at Ka-band is designed and fabricated in 45-nm CMOS-SOI technology. Using the proposed balun along with the push-push core, the designed doubler achieves a wideband performance. The design covers a bandwidth of 23-42 GHz with a fundamental rejection of better than 32 dBc. The peak conversion loss of this design is 3.5 dB, and the power consumption is only 3.5 mW. The overall size of the designed frequency doubler with all RF and DC pads is only 1.1 × 0.85 mm2.
University of Birmingham Active exploration of faces in police lineups increases discrimination accuracy

Eyewitness identifications play a key role in the justice system, but eyewitnesses can make errors, often with profound consequences. We used findings from basic science and innovative technologies to develop and test whether a novel interactive lineup procedure, wherein witnesses can rotate and dynamically view the lineup faces from different angles, improves witness discrimination accuracy compared to a widely used procedure in laboratories and police forces around the world—the static frontal-pose photo lineup. No novel procedure has previously been shown to improve witness discrimination accuracy. In Experiment 1, participants (N=220) identified culprits from sequentially presented interactive lineups or static frontal-pose photo lineups. In Experiment 2, participants (N=8,507) identified culprits from interactive lineups that were either presented sequentially, simultaneously wherein the faces could be moved independently, or simultaneously wherein the faces moved jointly into the same angle. Sequential interactive lineups enhanced witness discrimination accuracy compared to static photo lineups, and simultaneous interactive lineups enhanced witness discrimination accuracy compared to sequential interactive lineups. These finding were true both when participants viewed suspects who were of the same or different ethnicity/race as themselves. Our findings exemplify how basic science can be used to address the important applied policy issue on how best to conduct a police lineup and reduce eyewitness errors.
Trading Frictions and the Post-Earnings-Announcement Drift

We use laboratory experiments to analyze how the existence of trading frictions (a transaction fee and a ban on short selling and margin buying) affects occurrence and strength of the post-earnings-announcement drift. We find lower trading activity and higher asset prices in the presence of frictions. While the initial price reaction to earnings announcements is weaker, the strength of the PEAD is not materially affected. Trading strategies aimed at exploiting the PEAD are less profitable in the presence of frictions.
KIER DISCUSSION PAPER SERIES

This paper envisages whether an external habit effect can produce indeterminate equilibrium paths thereby generating endogenous investment fluctuations. In an otherwise standard optimal growth model with leisure, we find that an external habit effect can cause endogenous investment fluctuations if there is a proper habit effect together with a proper intertemporal elasticity of substitution. In a calibrated version of the model, we find that endogenous investment fluctuations are plausible when the habit effect is negative with the “catching up with the Joneses” effect.
KIER DISCUSSION PAPER SERIES

Extending the Kim (1989) model of endogenous labor specialization to an overlapping generations model with an endogenous technology choice, we show in this paper that, when the market size and the fixed costs associated with the technologies with labor specialization are small, the growth pattern of this economy depends on worker expectations. In other words, if workers expect low returns of specific human capital, they will not invest in such capital, and the economy will be eventually locked in an underdevelopment trap. On the other hand, if they expect high returns of specific human capital, they invest in such capital, and, as a result, the economy can exhibit long-run growth.
Planning at the urban periphery in Australia: issues relating to private residential back and front yards

This narrative focuses on three planning issues affecting the suburban residential periphery in Sydney, Australia: (i) amenity, (ii) biodiversity conservation and (iii) bushfire potential. All relate to private front and back yards, which provide key elements of the residential landscape. Embedded in the paper is the complexity of the planning system and the subsequent inconsistency between dealing with the three issues. Considerable attention is paid to local government and its changing legislative terrain. In particular, several local statutory planning instruments are investigated to illustrate this. The conclusion calls for further research while stressing more action is warranted within and outside the planning system in an integrated manner. Two significant matters comprise community support and regional structures.
Ageing in India: Socio-Economic and Health Dimensions

While this study essentially draws upon Indian conditions and data for analysing ageing and a few of its more critical dimensions involving socio-economic, health and public policy aspects, it may well be argued that each of these dimensions remains equally, if not more, important for many of the developing countries with transitioning demography (declining fertility and life prolongation) and liberalising economy (growing privatisation and pro-market reforms) rendering several non-market institutions void. From a thorough empirical review of the Indian situation using both the primary and secondary data sources, it has been observed that a bulk of the aged may not be able to withstand the unfolding economic realities either in India or elsewhere: they are socially at a loss because of their poor past, economically weak because of serious poverty issues, physically frail and suffer from functional dependence. They are also losing because of erosion in traditional familial values. Further, the non-elderly adults are yet to realise the need for planned ageing. The study tries to build the argument that many of these issues have not been fully understood while framing public responses to ageing. The upcoming concepts underlying 'elderly involvements in development' or 'healthy and active ageing' may not therefore hold true for many. The worst affected are the elderly women.

The Real Exchange Rate and Economic Growth

The real exchange rate was not at the center of the first generation of neoclassical growth models, nor was it prominent among the policy prescriptions that flowed from those models. Recent analyses, in contrast, have paid it more attention. This paper analyzes the role of the real exchange rate in the growth process, the channels through which the real exchange rate influences other variables, and policies useful (and not useful) for governing the real rate. An appendix provides econometric evidence supportive of the emphases in the text.
Numerical implementation and oceanographic application of the Gibbs thermodynamic potential of seawater

The 2003 Gibbs thermodynamic potential function represents a very accurate, compact, consistent and comprehensive formulation of equilibrium properties of seawater. It is expressed in the International Temperature Scale ITS-90 and is fully consistent with the current scientific pure water standard, IAPWS-95. Source code examples in FORTRAN, C++ and Visual Basic are presented for the numerical implementation of the potential function and its partial derivatives, as well as for potential temperature. A collection of thermodynamic formulas and relations is given for possible applications in oceanography, from density and chemical potential over entropy and potential density to mixing heat and entropy production. For colligative properties like vapour pressure, freezing points, and for a Gibbs potential of sea ice, the equations relating the Gibbs function of seawater to those of vapour and ice are presented.
Balancing hydropower and biodiversity in the Amazon, Congo, and Mekong

Basin-scale planning is needed to minimize impacts in mega-diverse rivers The world's most biodiverse river basins—the Amazon, Congo, and Mekong—are experiencing an unprecedented boom in construction of hydropower dams. These projects address important energy needs, but advocates often overestimate economic benefits and underestimate far-reaching effects on biodiversity and critically important fisheries. Powerful new analytical tools and high-resolution environmental data can clarify trade-offs between engineering and environmental goals and can enable governments and funding institutions to compare alternative sites for dam building. Current site-specific assessment protocols largely ignore cumulative impacts on hydrology and ecosystem services as ever more dams are constructed within a watershed (1). To achieve true sustainability, assessments of new projects must go beyond local impacts by accounting for synergies with existing dams, as well as land cover changes and likely climatic shifts (2, 3). We call for more sophisticated and holistic hydropower planning, including validation of technologies intended to mitigate environmental impacts. Should anything less be required when tampering with the world's great river ecosystems?

A Case Against a Four Percent In(cid:135)ation Target (cid:3)

We reformulate the standard New Keynesian model to include heterogeneity in price stickiness suggested by micro-evidence on price changes and to allow for positive trend in(cid:135)ation. In the new model, higher trend in(cid:135)ation leads to a relatively greater long-run output loss and, consequently, a smaller determinacy region than in the standard model. When trend in(cid:135)ation is 4%, the determinacy region of the new model is almost non-existent, cautioning against increasing the in(cid:135)ation target to 4% as a means to avoid the zero lower bound in the future and pointing to the costs that high in(cid:135)ation may have had in the past.
Biological communities at vent sites along the subduction zone off Oregon

An abundant deep-sea benthic community, dominated by the vestimentiferan tube worm, Lamellibrachia barhami, a giant white clam, Calyptogena sp. , and a second clam, Solemya sp. , was discovered along the northeast Pacific continental margin during dives of DSRV Alvin off Oregon. The localities are tectonically controlled and occur along submarine ridges that result from sediment deformation and accretion at the leading edge of plate subduction. Ancient sea-water buried with the sediment, dissolved methane and ammonia, and methane-derived carbonate are discharged to the ocean floor along this tectonically active margin. We hypothesize that the unusual benthic community is sustained by a chemosynthetic-energy metabolism based on the oxidation of methane by free living and symbiotic microbial populations. These organisms represent another significant adaptation of deep-sea biota to a site where the abundanc of food (in this case not directly related to particulate input from the sea surface but to tectonically generated methane), allows higher than normal levels of productivity and metabolism, despite the high pressures and low temperature of the deep-sea habitat. It is tempting to relate the global distribution of such faunas to chemosynthetic food sources generated by tectonic forces.
On the Long-Wavelength Validation of the SWOT KaRIn Measurement

The Surface Water and Ocean Topography (SWOT) mission will measure the sea surface height (SSH) using a Ka-band radar interferometer (KaRIn) over a swath off the nadir of the satellite tracks. The mission requires calibration and validation (CalVal) of the SSH wavenumber spectrum at wavelengths between 15 and 1000 km. The CalVal in the short-wavelength range (15–150 km) requires in situ observations. In the long-wavelength range (150–1000 km), the CalVal will use the onboard Jason-class nadir altimeter. Using a high-resolution global ocean simulation, this study identifies the spatial scales beyond which the nadir and off-nadir observations can be considered comparable. Our results suggest that the ocean signals at nadir can represent off-nadir ocean signals at wavelengths longer than 120 and 70 km along the midswath and the inner edge of the KaRIn grid, respectively, indicating that the nadir altimeter is able to fulfill its goal to validate the long-wavelength KaRIn measurement. The wavelength along the inner edge is limited around 70 km because the onboard nadir altimeter cannot resolve spatial scales longer than ~70 km. These wavelengths provide a reference point for the required spatial coverage of the SWOT SSH in situ CalVal.

Collaboration technologies play an increasingly important role in student teamwork in universities. With the proliferation of collaboration systems on the market and the wide range of features they offer, choosing an appropriate system can be an overwhelming task for college students. In this paper, the authors present an empirical study that aimed to help college instructors and students assess and select appropriate collaboration systems for their teamwork needs. They first identified and ranked the important features of collaboration systems for students through a web-based survey. Based on the survey results, the authors built an evaluation framework, in the form of weighted scoring tables, to help students systematically choose technologies that met their collaborative needs. They further demonstrated how to use those scoring tables for an undergraduate capstone class that had a term-long team project. The implications and future directions of the authors’ study are also discussed.
Thermodynamics of interspecies electron transfer: from syntrophy to parasitism

Interspecies Electron Transfer (IET) is a mechanism that allows energetic coupling between two microorganisms. It plays a key role in a wide range of environmental and biotechnological microbial ecosystems and stimulation of Direct Interspecies Electron Transfer (DIET) appears as an attractive way to boost anaerobic digestion. However, studies dealing with IET have, so far, mostly restrained on the possible syntrophic interactions supported by this mechanism. In the present work, the case of a fermentative bacterium receiving extracellular electrons while fermenting a substrate is considered. By applying microbial thermodynamics to experimental data previously published, we show that IET can promote a wide range of interactions such as mutualism, commensalism or parasitism. In the case of glycerol fermentation IET indeed leads to a diminution of bacterial biomass production concomitantly with an increased production of reduced compounds such as 1,3-propanediol. Thus, our study indicates that IET probably plays an important role nowadays underestimated in microbial interactions networks giving interesting perspectives for the optimization and control of bioprocesses using IET stimulation.
Impact of deforestation on the proposed mesoamerican biological corridor in Central America

This study uses the dry season Normalized Difference Vegetation Index (NDVI) of 1982 to 2000 derived from Advanced Very High Resolution Radiometer (AVHRR) to identify regions of substantial deforestation in Central America. High-resolution nested grid simulations, using the Colorado State University (CSU) Regional Atmospheric Modeling System (RAMS), are conducted over the identified regions of deforestation. These simulations examine cloud formation for three land use scenarios: 1) completely forested; 2) current land use; and 3) deforested conditions. In the deforestation scenario the locations of the proposed Mesoamerican Biological Corridor (MBC) are kept forested while pasture conditions are assumed for other areas. These simulations help identify locations where high deforestation has significant climatic impact on the proposed biological corridor. Model simulations show that with pastures surrounding forests in the proposed corridor, several locations within the corridor will have suppressed cloud formation.
lectrokinetic actuation of low conductivity dielectric liquids

Whilst electrohydrodynamic (EHD) flow actuation of dielectric fluids has been widely demonstrated, the fundamental mechanisms responsible for their behaviour is not well understood. By highlighting key distinguishing features of the various EHD mechanisms discussed in the literature, and proposing a more general mechanism based on Maxwell (electric) pressure gradients that arise due to induced polarization, we suggest that it is possible to identify the dominant EHD mechanisms that are responsible for an observed flow. We demonstrate this for a class of low conductivity dielectric fluids — Electro-Conjugate icrofluidics lectrohydrodynamics icropumping lectric pressure gradient nduced charge olarization Fluids (ECFs) — that have recently been shown to exhibit EHD flow phenomena when subjected to nonuniform fields of low intensities. Careful inspection of the salient attributes of the flow, at least at low field strengths (<1 kV/cm) — for example, the absence of a threshold voltage for the onset of flow, the quadratic scaling of the flow velocity with the applied voltage, and flow from the high to the low field region — eliminate the possibility of mechanisms based on space charge. Instead, we suggest that flow xiste xper can be attributed to the e agreement between our e
