Abstract:
Much evidence suggests that tumor necrosis factor-α (TNF-α) is involved in the regulation of physiological sleep. However, it remains unclear whether peripheral administration of TNF-α induces sleep in rats. Furthermore, the role of the vagus nerve in the somnogenic actions of TNF-α had not heretofore been studied. Four doses of TNF-α were administered intraperitoneally just before the onset of the dark period. The three higher doses of TNF-α (50, 100, and 200 μg/kg) dose dependently increased nonrapid eye movement sleep (NREMS), accompanied by increases in electroencephalogram (EEG) slow-wave

Fast and controllable cooling at nanoscales requires a combination of highly efficient passive cooling and active cooling. Although passive cooling in graphene-based devices is quite effective due to graphene’s extraordinary heat conduction, active cooling has not been considered feasible due to graphene’s low thermoelectric power factor. Here, we show that the thermoelectric performance of graphene can be significantly improved by using hexagonal boron nitride (hBN) substrates instead of SiO2.

We find that European SMEs significantly increased their net trade credit to sales ratio during the Great Recession. For the aggregate of SMEs, trade credit did not provide any buffer to the contraction in bank loans. In fact, through increased net trade credit, SMEs suffered a squeeze in their liquidity and this phenomenon reflects the weak bargaining power of SMEs in their trade credit relationship with larger firms. Therefore, increased net trade credit by SMEs does not reflect an efficient reallocation of credit, and it calls for policy actions. These policy actions are highly relevant, gi

Abstract:
If line-shape information was physically presented by virtue of some kind of mechanical interface, man-machine communication would be enhanced in the sense of multi-modal interactions. In order for such interactions to be available with ease, they should be realized as simple, small, and cheap devices even though suffering from a bit of performance decrease. Thus, the authors have studied a mouse-like computer-human mechanical interface. The idea is that slippage stimuli on a fingerpad would be effective enough to provide users a piece of motion information, and that the mechanism for slippage can be embodied in mouse interfaces. Here, to enhance the slippage perceptual performance, raised-dots were considered to be useful, and thus, a series of psychophysical experiments were carried out by using raised-dot planes with the period of 1.5, 3.1, 12.5, 30, and 50 mm, together with a without-dot flat plane. It was confirmed that the perceptual lengths were well formulated by a power law: they were proportional to the power of both speed and length. The exponential constants with the length factor were a little less than 1 corresponding to the ideal linear relationship. While the ones with the speed factor were in negative, nearly 0 corresponding to the ideal undisturbed relationship. Then, it was found that the pathway length perceptual accuracies for the raised-dot planes were much superior to that for the flat plane from the viewpoint of (1) length-related perceptual length contractions, (2) speed-induced perceptual length contractions, and (3) perceptual length random errors. This is shown in this chapter.

Abstract:
In most dielectrics, the linear relation between electric polarization and applied electric field is accurately obeyed even for fairly large fields of 107 V/m. The reason is that the atomic displacements are extremely small, in the range of nuclear sizes—millions of times smaller than the size of atoms. Though nonlinear effects such as electrostriction have been known for some time, it was not until the invention of the laser that sufficiently large optical fields became available to produce sizeable nonlinear optical effects. The induced polarization P can be written as a power series in an electric field, . . . P = χE + dE2 +· · · , . . . where χ is the linear electric susceptibility, and the higher-order terms lead to nonlinear effects such as second harmonic generation. The electric field associated with the incident light is sinusoidal, E = E0 sin ωt, and when E is substituted in the expression for P, a power series in sin ωt results. The second term is dE20 sin2 ωt = 1/2dE20 (1 − cos 2ωt), which includes a component of polarization with twice the frequency of the impressed field E. This rapidly oscillating induced dipole moment is the source of second harmonic light. The intensity of the light depends on the size of d, the second order coefficient. Crystal symmetry is a major factor in the second-order effect. The one-dimensional polar chain in Fig. 29.2 illustrates the origin of the quadratic term. When the applied field is directed to the left, the ions and bonding electrons are in very close contact and the displacements will be small because of short range repulsive forces. These forces do not oppose motion in the opposite direction, so that fields directed to the right give larger motions and larger polarizations. A centric chain does not show this effect. Such a chain can give rise to odd-order terms producing saturation but not to even power terms in the P(E) relation. This means that centric crystals are useless as second harmonic generators.

This chapter draws out the implications of Hannah Arendt’s interpretation of power for thinking about the nuclear revolution. Drawing on Arendt’s distinction between violence and power, it posits that nuclear weapons are powerful not simply because they are destructive, but because the fact of their destructiveness induces statesmen to behave in practice as if power and violence were in fact opposites. This Arendtian approach providing a conceptual foundation for a particular strand of American thinking about nuclear disarmament. Rather than a push from the past, nuclear weapons reveal power to be more like a pull from the future. Their power is not reducible to the rituals of deterrence, but rather from the fact that thermonuclear annihilation has fundamentally altered the human relationship to the planet.

Abstract:
Most of the intellectual production in the social sciences is the outcome of an implicit assumption that we are still living in a State System when in fact the globalization of the economy is reducing the States’ ability to adopt proper rules to address societal issues. To understand this state of affairs, it is important to understand the role played by property in the operation of the liberal Power System. Property is a right of autonomy constitutionally protected. Its justification can be found either in the defence of the individual’s autonomy or via efficiency considerations. The fact is, however, that a sizable proportion of productive property today is concentrated in large, corporate organizations. The exploitation of the possibilities offered by an international open economy to these organizations has led to the production of potentially deadly negative externalities such as climate change, unbearable inequalities and the impoverishment of public institutions. The development of these large organizations has induced changes in the operation of the Power System. They must be understood to identify the existing potential means of action, in particular via proper rules of accounting for the impact of their activities.

Abstract:
This chapter looks at democracy, legitimacy, and accountability in Euro crisis management. It looks at the main critiques of the EU’s response to the crisis. It will be shown that scholars in this area castigate the EMU governance framework for its shortcomings in terms of input, output, and social legitimacy. The chapter makes the case for increased democratic controls and intense inter-institutional dialogue in the functioning of the EMU. It demonstrates how the crisis-induced developments have impacted on the horizontal and vertical distribution of power in the EU and the Member States. First, more powers were conferred on the Commission, Council, and Eurogroup in the measures enacted to combat the crisis. Though the European Parliament was heavily involved in norm production and had a pretty good strike rate in getting its amendments included in the final legislation, its role in policy implementation remains minimal. Second, the EU legislature put much of its reforming faith in a new recruit to strengthen democratic control in the EMU—the national parliaments. The crisis-induced legal and economic developments have circumscribed their budgetary sovereignty in many ways, but the newly enacted rules also serve to empower them vis-à-vis the executive. Third, the de facto division between borrower and lender states might have a bearing on the intra-institutional balance of power in the EU, and the emerging patterns of geographical fragmentation threaten the unity of the EU-28. The chapter set outs concrete proposals on how to enhance transparency and accountability in the EMU.

Abstract:
Chapter 4 applies the proportionality model to two cases of IO exceptionalism at the United Nations (UN) Security Council. First, it explains the normalization of the Council’s self-asserted emergency power to act as a global legislator. After 9/11, the Council, for the first time, decreed abstract, general, and indefinite rules to the entire international community. Despite opposition in the aftermath, it was capable to arrogate a permanent de facto legislative competence by credibly justifying the measures as necessary. Second, the chapter accounts for the constitutional containment of the Council’s regime of targeted sanctions against terror suspects. Through Resolution 1390 (2002), the UN Security Council implemented the so-called “terror lists” financially sanctioning all listed individuals without providing for a legal remedy. Against the preferences of the most powerful states, a coalition of societal actors and courts successfully induced procedural improvements by delegitimizing the measures as excessive.

Abstract:
The outbreak of conflicts in parts of the Middle East and North Africa since 2011 has turned cities into contentious spaces and primary sites hosting large numbers of refugees and undocumented migrants. Yet, the lack of economic perspectives and human rights' violations are push factors for emigration in a number of countries beyond the Mediterranean facing a gap in comprehensively addressing migratory challenges from a broad-based perspective. How can urbanization be addressed concerning the discourse about conflict-induced displacement without first identifying the noncitizen? Considering forced displacement induced by war/environmental disaster, this chapter situates its discussion of global displacement, war, and non-citizenship by exploring the interplay between place, power, and politics. It argues for deconstructing non-citizenship and reinstating displacement in the city by analysing the decision-making processes and experiences of non-citizens in the cities of Jeddah, Doha, and Beirut, while expanding the issue of statelessness to post-earthquake Haïti.

Abstract:
Traditionally, urbanization is hailed as an important force for socio-economic development of countries. In fact, recent research on Africa suggests that urbanization has the potential to stimulate socio-economic development. Yet, many African countries experiencing rapid urban growth continue to bear a disproportionate amount of the costs associated with urbanization (e.g., increased urban poverty, and energy crisis among others). This is in sharp contradiction to the popular notion that urbanization is a stimulus for socio-economic development. Using Ghana as a case study, this chapter discusses the extent to which rapid urbanization influences power supply and the implications on socio-economic development. The chapter focuses on four issues: (1) the history of power and urbanization in Ghana; (2) the influence of urbanization on power crisis in Ghana; (3) the socio-economic implications of urbanization-induced power crisis; and (4) the policies available in addressing the power crisis.

Full text
Abstract:
Wireless power transfer (WPT) technologies have received much more attention during the last decade due to their effectiveness in wireless charging for a wide range of electronic devices. To transmit power between two points without a physical link, conventional WPT systems use two coils, one coil is a transmitter (Tx) and the other is a receiver (Rx) which generates an induced current from the received power. Two main factors control the performance of the WPT schemes, power transfer efficiency (PTE) and transmission range. Power transfer efficiency refers to how much power received by the rechargeable device compared to the power transmitted from the transmitter; while transmission range indicates the longest distance between transmitter and receiver at which the receiver can receive power within the acceptable range of power transfer efficiency. Several studies were carried out to improve these two parameters. Many techniques are used for WPT such as inductive coupling, magnetic resonance coupling, and strongly coupled systems. Recently, metamaterial structures are also proposed for further transfer efficiency enhancement. Metamaterials work as an electromagnetic lensing structure that focuses the evanescent transmitted power into receiver direction. Transmitting & Receiving antenna systems may be used for sending power in certain radiation direction. Optimizing the transmitter antenna and receiver antenna characteristics increase the efficiency for WPT systems. This chapter will present a survey on different wireless power transmission schemes.

The high density of the sensors on the pipe allowed for analysis that had not previously been done. Two methodologies are presented to locate the area of the region that is the source of the vibration. In VIV, the current which causes the vibrations is important, beca

Abstract:
Feedwater heaters have suffered premature failures in the desuperheating zone resulting from a combination of high cross flow velocities and relatively long baffle spacing. High steam flows coupled with longer unsupported tube spans necessary to keep pressure drops low and tube walls dry create an increased probability for flow induced vibration. This vibration is primarily the result of a fluidelastic whirling of the tube. The most significant factor in the calculation of the natural frequency of the tube is unsupported span length. The natural frequency varies as the square of the unsupporte

Abstract:
This paper focuses on the formulation and validation of a novel approach for the expedient estimation of the maximum amplification factor induced by mistuning in damped bladed disks. This computational approach is based on earlier analytical results yielding an upper bound of the maximum amplification factor in the limit of zero damping. Extensions of these results are derived first to broaden the applicability of the methodology. Next, the computational technique is described: it involves the components of one of the mode shapes of the mistuned disk and the associated frequency as the variabl
