The key process is intermediary metabolism, by which the energy stored in reserves (glycogen, starch, lipid, protein) is transferred to ATP. In aerobic respiration the electrons released from reserves are passed to oxygen, which is thereby reduced to water.

Abstract:
AbstractComputational human head models have been used in studies of brain stimulation. These models have been able to provide useful information that can’t be acquired or difficult to acquire from experimental or imaging studies. However, most of these models are purely volume conductor models that overlooked the electric excitability of axons in the white matter of the brain. We hereby combined a finite element (FE) model of electroconvulsive therapy (ECT) with a whole-brain tractography analysis as well as the cable theory of neuronal excitation. We have reconstructed a whole-brain tractogram with 2000 neural fibres from diffusion-weighted magnetic resonance scans and extracted the information on electrical potential from the FE ECT model of the same head. Two different electrode placements and three different white matter conductivity settings were simulated and compared. We calculated the electric field and second spatial derivatives of the electrical potential along the fibre direction, which describes the activating function for homogenous axons, and investigated sensitive regions of white matter activation. Models with anisotropic white matter conductivity yielded the most distinctive electric field and activating function distribution. Activation was most likely to appear in regions between the electrodes where the electric potential gradient is most pronounced.

Abstract:
AbstractContinuous technology scaling has increased the susceptibility of today’s electronic devices to manufacturing tolerances and environmental changes. The resulting uncertainty in component reliability can be only approximated or estimated at design time and might propagate to system level. Therefore, uncertainty must be considered to enable the design of robust systems. In this chapter, we propose a methodology for cross-level reliability analysis to tame the ever increasing analysis complexity of contemporary systems under the influence of uncertainties. The presented methodology combines various reliability analysis techniques across different levels of abstraction while providing an explicit modeling of uncertainties. It introduces mechanisms for (a) the composition and decomposition of the system during analysis and (b) converting analysis data between different levels of abstraction through adapters. The developed analysis techniques are integrated in an automatic electronic system-level reliability analysis tool to allow for the evaluation of reliability-increasing techniques and for DSE!. The tool thereby uses meta-heuristic algorithms for optimization and enables the comparison of system implementation candidates with objectives represented by uncertainty distributions.

Abstract:
AbstractToday, many battery-operated cyber-physical systems (CPS) ranging from domestic robots, to drones, and electric vehicles are highly software-intensive. The software in such systems involves multiple feedback control loops that implement different functionality. How these control loops are designed is closely related to both the semiconductor aging of the processors on which the software is run and also the aging of the batteries in these systems. For example, sudden acceleration in an electric vehicle can negatively impact the health of the vehicle’s battery. On the other hand, processors age over time and stress, impacting the execution of control algorithms and thus the control performance. With increasing semiconductor scaling, and our increasing reliance on battery-operated devices, these aging effects are of concern for the lifetime of these devices. Traditionally, the design of the control loops focused only on control-theoretic metrics, related to stability and performance (such as peak overshoot or settling time). In this chapter we show that such controller design techniques that are oblivious of the characteristics of the hardware implementation platform dramatically worsen the battery behaviour and violate the safety requirement with processor aging. However, with proper controller design these effects can be mitigated—thereby improving the lifetime of the devices.

Abstract:
AbstractTumor-treating fields (TTFields) are alternating fields (200 kHz) used to treat glioblastoma (GBM), which is one of the deadliest cancer diseases of all. Glioblastoma is a type of malignant brain cancer, which causes significant neurological deterioration and reduced quality of life, and for which there is currently no curative treatment. TTFields were recently introduced as a novel treatment modality in addition to surgery, radiation therapy, and chemotherapy. The fields are induced noninvasively using two pairs of electrode arrays placed on the scalp. Due to low electrical conductivity, significant currents are shielded from the intracranial space, potentially compromising treatment efficacy. Recently, skull remodeling surgery (SR-surgery) was proposed to address this issue. SR-surgery comprises the formation of skull defects or thinning of the skull over the tumor to redirect currents toward the pathology and focally enhance the field intensity. Safety and feasibility of this concept were validated in a clinical phase 1 trial (OptimalTTF-1), which also indicated promising survival benefits. This chapter describes the FE methods used in the OptimalTTF-1 trial to plan SR-surgery and assess treatment efficacy. We will not present detailed modeling results from the trial but rather general concepts of model development and field calculations. Readers are kindly referred to Wenger et al. [1] for a more general overview of the clinical implications and applications of TTFields modeling.

Full text
Abstract:
Electrolysis makes use of electric currents, a stream of electrons, to bring about chemical change. It puts electricity to work by using it to break or form bonds by forcing electrons on to molecules or sucking electrons out of them. Electrolysis is an application of the redox processes I described in Reaction 5, where I showed that reduction is the gain of electrons and that oxidation is their loss. All that happens in electrolysis is the use of an external supply of electrons from a battery or other direct-current (DC) source to push them on to a species and so bring about its reduction, or the use of the electron-sucking power of a battery to remove them from a species to bring about its oxidation. Electrolysis, in other words, is electrically driven reduction and oxidation. In fact, the process is rather broader than just forcing species to accept or give up electrons because, as I have hinted, molecules might respond to the change in their number of electrons by discarding or rearranging atoms. For instance, when water is electrolysed, the H–O bonds of the H2O molecules are broken and hydrogen and oxygen gases are formed. When an electric current is passed through molten common salt (sodium chloride, NaCl), metallic sodium and gaseous chlorine, Cl2, are formed. Electrolysis is a major technology in the chemical industry, for among other applications it is used to make chlorine, to purify copper, and to extract aluminium. To bring about electrolysis, two metal or graphite rods, the ‘electrodes’, are inserted into the molten substance or solution and connected to a DC electrical supply. The electrons that form the electric current enter the substance through one electrode (the ‘cathode’) and leave it through the other electrode (the ‘anode’). A molecule or ion close to the cathode is forced to collect one or more electrons from that electrode and be reduced. A molecule or ion close to the anode is forced to release them to that electrode and thereby become oxidized. A reasonably simple first example is the purification of copper.

Abstract:
Nowadays, information and communication technologies (ICT) are being used in the mental health field to improve the quality of the services provided. Several studies refer both advantages and disadvantages for these practices. E-therapy appears as a new way to help people in their life and existing relationships, and there is proven evidence that online therapy helps, for instance, to reduce depression symptoms. It is also seen as a complement of the technological and traditional techniques, to improve the effectiveness and efficiency of the therapeutic process. As a matter of fact, some people tend to be more comfortable with the computer than in face-to-face therapy. Besides patients and physicians, other direct players could be found in this domain, namely, families and caregivers. All players will be directly affected by the use of existing services and thus, a correct assessment of the effectiveness of e-therapy solutions and studies is required. eSchi is a multimedia portal that enables an e-therapy setting for schizophrenia patients. Currently under development, the system is described and future trends in the area are depicted.

Full text
Abstract:
Photodynamic therapy (PDT) is a less-invasive treatment of cancer and precancerous lesions. Porphyrin derivatives have been used and studied as the photosensitizers for PDT. In general, the biomacromolecules oxidation by singlet oxygen, which is produced through energy transfer from the photoexcited photosensitizers to oxygen molecules, is an important mechanism of PDT. However, the traditional PDT effect may be restricted, because tumors are in a hypoxic condition and in certain cases, PDT enhances hypoxia via vascular damage. To solve this problem, the electron transfer-mediated oxidation of biomolecules has been proposed as the PDT mechanism. Specifically, porphyrin phosphorus(V) complexes demonstrate relatively strong photooxidative activity in protein damage through electron transfer. Furthermore, other photosensitizers, e.g., cationic free-base porphyrins, can oxidize biomolecules through electron transfer. The electron transfer-supported PDT may play the important roles in hypoxia cancer therapy. Furthermore, the electron transfer-supported mechanism may contribute to antimicrobial PDT. In this chapter, recent topics about the biomolecules photooxidation by electron transfer-supported mechanism are reviewed.

Abstract:
Dye Sensitized Solar Cell (DSSC) has great advantages over conventional silicon-based photovoltaics as it is inexpensive, flexible, and transparent. Sun energy is used to excite the electron of the organic (ruthenium-polypyridine) dye from which the electron from the dye is injected into the anode made of titanium dioxide (TiO2). The excited electron enters the conduction band of the TiO2 and gets transmitted across the TiO2 nanoparticles (anode) to the FTO (Fluorine-doped tin-oxide) glass/electrode, which in turn go to the external circuit powering the electrical load. The electron returns to

Abstract:
This work reports on the coupled electro-mechanical simulation and mechanical characterization of electro-bonded laminates (EBL). In light of their conceivable implementation in morphing wings as leading/trailing edge reinforcement plates or as active elements for shear center position adaptation, values of shear strength comparable to those achievable by an epoxy resin, i.e. 10–15 [MPa], are needed. Finite element analysis routines have been implemented to gain insights into the shear behavior of EBL under high electric fields. Further, they allowed for the optimization of EBL in terms of ele

Abstract:
This paper demonstrates experimentally, theoretically, and numerically a wide-range tunability of electrothermally actuated MEMS arch beams. The beams are made of silicon and are intentionally fabricated with some curvature as in-plane shallow arches. Analytical results based on the Galerkin discretization of the Euler Bernoulli beam theory are generated and compared to the experimental data and results of a multi-physics finite-element model. A good agreement is found among all the results. The electrothermal voltage is applied between the anchors of the clamped-clamped MEMS arch beam, genera

Abstract:
Electroporation is a non-linear biophysical mechanism in which the application of an external pulsed electric field leads to an increase in the permeability of cellular membranes. The extent of electroporation is attributed to the induced buildup of charge across the membrane, and consequently, transmembrane potential (TMP). Increasing the TMP has been described to produce various permeabilizing effects, wherein the formation of hydrophilic, aqueous pores becomes energetically favorable [1]. If the pulse parameters are tuned such that the membrane defects are only temporary, and the cell remai

With the anticipated growth in the electric vehicle market, advances in power electronics used in electric drivetrain, battery charging systems, etc. are delivering higher power densities, and with them, associated thermal challenges for operation in relatively closed vehicular systems. As such, the framework of reliability qualifications of electronic devices need to be reconsidered as system needs have moved beyond typical consumer electronic device needs, such as laptops or entertainment devices, where safe operation and longevity is essential to electric vehicle market viability.

Abstract:
This paper presents a numerical model assessing the potential of ionic wind as a heat transfer enhancement method for the cooling of grid distribution assets. Distribution scale power routers (13–37 kV, 1–10 MW) have stringent requirements regarding lifetime and reliability, so that any cooling technique involving moving parts such as fans or pumps are not viable. Increasing the air flow — and thereby enhancing heat transfer — through Corona discharge could be an attractive solution to the thermal design of such devices.

[Extract from Executive Summary] The competition for space from competing sectors in the coastal waters of Scotland has never been greater and thus there is a growing a need for interactive seascape planning tools that encompass all marine activities. Similarly, the need to gather data to inform decision makers, especially in the fishing industry, has become essential to provide advice on the economic impact on fishing fleets both in terms of alternative conservation measures (e.g. effort limitations, temporal and spatial closures) as well as the overlap with other activities, thereby allowing
