Full textAbstract:
This chapter presents the basic elements of the kinetic theory of non-ideal fluids, to which both kinetic and potential energy contribute on comparable footing. Non-ideal fluids lie at the heart of many complex fluid-dynamic applications, such as those involving multiphase and multicomponent flows. This chapter features a degree of abstraction which may not come by handy to the reader with limited interest to the formal theory of classical many-body systems. The interested readers can safely skip the math and retain the basic bottomline. They may just skip this chapter altogether, but in this author’s opinion, this is likely to come with a toll on the full appreciation of Lattice Boltzmann theory for non-ideal fluids, in fact one of the most successful offsprings of Lattice Boltzmann theory.

Full textAbstract:
Until the mass citizenship grant of 212 CE, Roman law served Roman citizens almost exclusively. However, since the non-Romans’ legal systems generally sufficed, this marginalised status regarding Roman law was generally of little importance. Within the Roman citizen body, the Roman legal system marginalised many because of its expense and preferential treatment of the wealthy. In addition the culture, but not the legal system, through infamia marginalised some for what they did and the kind of person they were. While marginalised in modern eyes, Roman law treated women, freedmen, children and slaves as important participants in a wide range of societal functions, giving them specific abilities as well as disabilities. The most severe legal marginalisation occurred as the laws systematically and increasingly marginalised the humble citizens (humiliores) and evermore favoured the elite (honestiores). The system also treated outlaws, magicians, some cults and, later, Christians as outside the law’s Pale.

Clinicians and researchers have previously focused on the neurologic and psychiatric aspects of Huntington’s disease (HD). However, it is becoming evident that many neurodegenerative disorders are also complicated by pathology in tissues outside the brain. Although many clinical features of HD can be ascribed to neuronal loss and dysfunction, there is accumulating evidence indicating a role for the pathology of non-neuronal tissues in the disease process. Mutant huntingtin is expressed throughout the body and may induce pathology in parallel in both the brain and other organs. Insights into peripheral pathology in HD have the potential of improving knowledge of key pathogenic mechanisms. This chapter describes peripheral manifestations of HD, including weight loss, muscle wasting, and cardiac dysfunction, and discusses how these might constitute targets for drug treatment as well as offering disease modeling systems and potential sources of biomarkers.

Full textAbstract:
Endocrine abnormalities are very common in patients with chronic autoimmune rheumatic diseases (CARDs) due to the systemic involvement of the central nervous system and endocrine glands. In recent years, the response of the endocrine (and also neuronal) system to peripheral inflammation has been linked to overall energy regulation of the diseased body and bioenergetics of immune cells. In CARDs, hormonal and neuronal pathways are outstandingly important in partitioning energy-rich fuels from muscle, brain, and fat tissue to the activated immune system. Neuroendocrine regulation of fuel allocation has been positively selected as an adaptive programme for transient serious, albeit non-life-threatening, inflammatory episodes. In CARDs, mistakenly, the adaptive programmes are used again but for a much longer time leading to systemic disease sequelae with endocrine (and also neuronal) abnormalities. The major endocrine alterations are depicted in the following list: mild activation of the hypothalamic-pituitary-adrenal axis and the sympathetic nervous system, inadequate secretion of ACTH and cortisol relative to inflammation, loss of androgens, inhibition of the hypothalamic-pituitary-gonadal axis and fertility problems, high serum levels of oestrogens relative to androgens, fat deposits adjacent to inflamed tissue, increase of serum prolactin, and hyperinsulinaemia (and the metabolic syndrome). Neuroendocrine abnormalities are demonstrated using this framework that can explain many CARD-related endocrine disturbances. This chapter gives an overview on pathophysiology of neuroendocrine alterations in the context of energy regulation.

Full textAbstract:
Anaesthesia induces changes in many organ systems within the body, though clearly none more so than the central nervous system. The physiology of the normal central nervous system is complex and the addition of chronic pathology and polypharmacy creates a significant challenge for the anaesthetist. This chapter demonstrates a common approach for the anaesthetist and specific considerations for a wide range of neurological conditions. Detailed preoperative assessment is essential to gain understanding of the current symptomatology and neurological deficit, including at times restrictions on movement and position. Some conditions may pose challenges relating to communication, capacity, and consent. As part of the consent process, patients may worry that an anaesthetic may aggravate or worsen their neurological disease. There is little evidence to support this understandable concern; however, the risks and benefits must be considered on an individual patient basis. The conduct of anaesthesia may involve a preference for general or regional anaesthesia and requires careful consideration of the pharmacological and physiological impact on the patient and their disease. Interactions between regular medications and anaesthetic drugs are common. Chronically denervated muscle may induce hyperkalaemia after administration of succinylcholine. Other patients may have an altered response to non-depolarizing agents, such as those suffering from myasthenia gravis. The most common neurological condition encountered is epilepsy. This requires consideration of the patient’s antiepileptic drugs, often relating to hepatic enzyme induction or less commonly inhibition and competition for protein binding, and the effect of the anaesthetic technique and drugs on the patient’s seizure risk. Postoperative care may need to take place in a high dependency unit, especially in those with limited preoperative reserve or markers of frailty, and where the gastrointestinal tract has been compromised, alternative routes of drug delivery need to be considered. Overall, patients with chronic neurological conditions require careful assessment and preparation, a considered technique with attention to detail, and often higher levels of care during their immediate postoperative period.

Full textAbstract:
This book focuses on a method for exploring, explaining, and understanding the behavior of large many-body systems. It describes an approach to non-equilibrium behavior that focuses on structures (represented by correlation functions) that characterize mesoscale properties of the systems. In other words, rather than a fully bottom-up approach, starting with the components at the atomic or molecular scale, the “hydrodynamic approach” aims to describe and account for continuum behaviors by largely ignoring details at the “fundamental” level. This methodological approach has its origins in Einstein’s work on Brownian motion. He gave what may be the first instance of “upscaling” to determine an effective (continuum) value for a material parameter—the viscosity. His method is of a kind with much work in the science of materials. This connection and the wide-ranging interdisciplinary nature of these methods are stressed. Einstein also provided the first expression of a fundamental theorem of statistical mechanics called the Fluctuation-Dissipation theorem. This theorem provides the primary justification for the hydrodynamic, mesoscale methodology. Philosophical consequences include an argument to the effect that mesoscale parameters can be the natural variables for characterizing many-body systems. Further, the book offers a new argument for why continuum theories (fluid mechanics and equations for the bending of beams) are still justified despite completely ignoring the fact that fluids and materials have lower scale structure. The book argues for a middle way between continuum theories and atomic theories. A proper understanding of those connections can be had when mesoscales are taken seriously.

Full textAbstract:
Over the past decades, a great body of theoretical and mathematical work has been devoted to random-matrix descriptions of open quantum systems. This chapter reviews the physical origins and mathematical structures of the underlying models, and collects key predictions which give insight into the typical system behaviour. In particular, the aim is to give an idea how the different features are interlinked. The chapter mainly focuses on elastic scattering but also includes a short detour to interacting systems, which are motivated by the overarching question of ergodicity. The first sections introduce general notions from random matrix theory, such as the 10 universality classes and ensembles of Hermitian, unitary, positive-definite, and non-Hermitian matrices. The following sections then review microscopic scattering models that form the basis for statistical descriptions, and consider signatures of random scattering in decay, dynamics, and transport. The last section touches on Anderson localization and localization in interacting systems.

Density functional theory (DFT) has established itself as a very capable platform for modelling from first principles electronic, optical, mechanical and structural properties of materials. Starting out from the Dirac equation for the many-body system of electrons and nuclei, an effective theory has been developed allowing for materials specific and parameter free simulations of non-magnetic and magnetic solid matter. In this Chapter an introduction will be given to DFT, the Hohenberg-Kohn theorems, the Kohn-Sham equation, and the formalism for how to deal with non-collinear magnetism.

Full textAbstract:
The faculty to generate patterns is a basic feature of living systems. This chapter concentrates on patterns used in the context of control of behavior. Spatio-temporal patterns appear as quasi-rhythmic patterns mainly in the domain of locomotion (e.g. swimming, flying, walking). Such patterns may be rooted directly in the nervous system itself, or may emerge in interaction with the environment. The examples given show simulation of the corresponding behaviors that in most cases are applied to robots (e.g. walking in an unpredictable environment). In addition, non-rhythmic patterns will be explained which are linked to internal states and are required to select specific behaviors and control behavioral sequences. Such states may be relevant for top-down attention and may or may not be accompanied with subjective experiences, then called mind patterns. Specific cases concern the application of an internal body model, as well as states characterized as cognitive or as conscious.

Full textAbstract:
Malignant neoplastic disease includes a vast range of conditions that can originate from and can directly or indirectly affect virtually every organ system of the body. As a consequence of this, the presentation of malignancy can be similarly varied. While a diagnosis of malignancy may be clinically obvious in some cases, in others diagnosis and investigation may be delayed due to non-specific presentations and the attribution of symptoms to non-malignant conditions. Early diagnosis of cancer has an impact on the success of subsequent treatment and overall survival. It is therefore vital to maintain an appropriate level of clinical suspicion when deciding whether and how much to investigate patients with symptoms that could be secondary to an underlying malignancy.

Full textAbstract:
The mechanism for maintaining balance in man is complex. Vision, proprioception, and vestibular inputs are integrated in the central nervous system, and modulated by activity from the cerebellum, the extrapyramidal system, the reticular formation, and the cortex. This integrated, modulated information provides one mechanism for control of oculomotor activity, controls posture, gait, and motor skills and allows perception of the head and body in space. Recent evidence also supports an effect upon autonomic function, cognition, and emotion. The complexity of the system is such that pathology in a variety of different bodily systems, including the endocrine system, the cardiovascular system, and the haemopoietic system, can impact upon vestibular activity, in addition to primary otological and neurological pathology.Patients with dysfunction in the vestibular end-organs or vestibular pathways commonly complain of symptoms of dizziness, vertigo, unsteadiness, light-headedness, imbalance, and a plethora of synonyms associated with a sense of instability. Not infrequently, in an attempt to define their ‘unphysiological’ experience, patients use rather vague and imprecise semantics. The clinical distinction between dizziness, a symptom of non-specific pathological significance, and vertigo, a hallucination or illusion of movement, is rarely made, although the latter is a cardinal manifestation of a disorder of the vestibular system (Dix 1973). Ten to 20 per cent of all ‘dizzy’ patients are reportedly seen in neurology clinics (Dieterish 2004), therefore it behoves the neurologist to have a clear diagnostic strategy, including knowledge of detailed neuro-otological examination, to enable appropriate diagnosis and management of the patient with vestibular symptoms.

Full textAbstract:
That part of the clinical interface between neurology and general medicine occupied by inflammatory and immunological diseases is neither small nor medically trivial. Neurologists readily accept the challenges of ‘primary’ immune diseases of the nervous system: these tend to be focussed on one particular target such as oligodendrocytes or the neuro-muscular junction present in predictable ways, and are amenable as a rule to rational, methodological diagnosis, and occasionally even treatment. This is proper neurology.‘Secondary’ neurological involvement in diseases mainly considered systemic inflammatory conditions—for example, SLE, sarcoidosis, vasculitis, and Behçet’s—is a rather different matter. It may be difficult enough to secure such a diagnosis even when systemic disease has previously been diagnosed and new neurological features need to be differentiated from iatrogenic disease, particularly drug side effects or the consequences of immune suppression. But all the diseases mentioned may present with and confine themselves wholly to the nervous system; they may mimic one another, and pursue erratic and unpredictable clinical courses. In central nervous system disease, diagnosis by tissue biopsy is potentially hazardous and unattractive. Few neurologists enjoy excesses of confidence or expertise when faced with such clinical problems: the cautious diagnostician is perplexed, and the evidence-based neuroprescriber confounded. Unsurprisingly, great variations in approaches to diagnosis and management are seen (Scolding et al. 2002b).But rheumatologically inclined general, renal or respiratory physicians, comfortable when managing inflammation affecting their system or indeed other parts of the body designed to support the nervous system, are generally also ill at ease when faced with neurological features whose differential diagnosis may be large, particularly given the near universal diagnostic non-specificity of either imaging or CSF analysis.Here then is the subject material for this chapter: the diagnosis and management of central nervous system involvement in inflammatory and immunological systemic diseases (Scolding 1999a). In not one of these neurological conditions has a single controlled therapeutic trial been reported, and much that is published on these conditions is misleading or inaccurate. And yet the frequency with which the diagnosis is only confirmed or even first emerges at autopsy bears stark witness to both the severity and evasiveness of these disorders.

Full textAbstract:
Tremors are characterized by rhythmic oscillations of one or more body parts. Although typically seen in the upper limbs, almost any area may be involved, including the trunk, head, facial muscles, and legs. Sometimes, tremor is not visible at all but may be heard or palpated, for example, in vocal or orthostatic tremor, respectively. In neurological practice, the diagnosis and treatment of tremor is an everyday problem. A common scenario is the distinction between essential tremor and Parkinson’s disease. In this chapter, the wide range of tremors are discussed, with their aetiolology, pathophysiology, diagnosis and management described.Ataxia is a term used to describe a wide range of neurological disorders affecting muscle coordination, speech and balance that reflect dysfunction of a part of the central nervous system involved in motor function. Many of ataxias have a cerebellar pathology as root cause, although it must be remembered that ataxia, clumsiness, disordered ocular motility, dysarthria, and even kinetic or intention tremor are not always caused by cerebellar disease. This chapter describes the wide range of cerebellar disorders and ataxias, as are non-cerebellar ataxias such as Friedreich’s ataxia.

Full textAbstract:
This chapter discusses the law on creditor claims in Mexico. Insolvency proceedings in Mexico aim for an orderly liquidation procedure of all of the bankrupt’s assets to allow an equally orderly distribution of proceeds among creditors under the principle of par conditio creditorum (equal treatment for all creditors). Ideally, the body of law regulating this procedure should match the insolvency law of each country, so that the process can be effected congruently and logically. However, social policies and other commercial considerations have created systems of priorities in asset distribution that vary from country to country as a function of the policies of each. In many cases, the only commonality in all systems is that ordinary unsecured creditors collect last, if at all. Mexico is no exception, specifically in the treatment of claims arising out of a labour relationship, which in turn is derived from the overly protective and outdated regime established by the federal constitution for workers. The remainder of the chapter deals with insolvency claims, administration claims, and non-enforceable claims in turn. Each section examines: the definition and scope of the claim; rules for submission, verification, and satisfaction or admission of claims; ranking of claims; and voting and other participation rights in insolvency proceedings.

Full textAbstract:
Hyperthermia is a state of elevated core temperature that rises rapidly above 40°C, secondary to failure of thermoregulation. Hyperthermia has many causes, but it is the hallmark of three conditions—heatstroke, malignant hyperthermia, and neuroleptic malignant syndrome. The clinical and metabolic alterations of hyperthermia, if left untreated, can culminate in multiple organ system failure and death. High temperature causes direct cellular death and tissue damage. The extent of tissue injury is a function of the degree and duration of hyperthermia. Heat-induced ischaemia-reperfusion injury, and exacerbated activation of inflammation and coagulation are also contributory. Hyperthermia is a true medical emergency with rapid progression to multiple organ system failure and death. The primary therapeutic goal is to reduce body temperature as quickly as possible using physical cooling methods, and if indicated, the use of pharmacological treatment to accelerate cooling. There is no evidence of the superiority of one cooling technique over another. Non-invasive techniques that are easy to use and well-tolerated are preferred. Pharmacological cooling with Dantrolene sodium is crucial in the treatment of malignant hyperthermia.

Full textAbstract:
An understanding of pharmacokinetics is vital for the practice of anaesthesia. Drugs are, after administration, distributed throughout the body to the effect site (mostly the brain) to exert their effects. This can be influenced by differences in protein binding, systemic blood flow, and concomitant medication. Elimination of drugs from the body is through two main routes: either unchanged through the kidneys or through metabolism by the liver (and consecutive excretion through the kidneys). This process depends on the amount of hepatic blood flow and the amount of hepatic extraction. This in turn depends on the amount of protein binding and the intrinsic hepatic clearance. The cytochrome P450 enzyme family also plays an important role in drug elimination. Individual differences in enzyme activity can lead to differences in drug effect and clearances. Changes in enzyme activity by enzyme induction and inhibition can also be of influence on drug clearance. Compartmental, non-compartmental, and physiologically based models, and various statistical approaches to estimate these models, may be used to analyze the distribution and elimination of anaesthetic agents.

Full textAbstract:
Chapter 4 introduces the Schwinger Action Principle, along with associated particle and potential sources. While the methods described here originally arose in the relativistic quantum field theory of elementary particle physics, they have also profoundly advanced our understanding of non-relativistic many-particle physics. The Schwinger Action Principle is a quantum-mechanical variational principle that closely parallels the Hamilton Principle of Least Action of classical mechanics, generalizing it to include the role of quantum operators as generalized coordinates and momenta. As such, it unifies all aspects of quantum theory, incorporating Hamilton equations of motion for those operators and the Heisenberg equation, as well as producing the canonical equal-time commutation/anticommutation relations. It yields dynamical coupled field equations for the creation and annihilation operators of the interacting many-body system by variational differentiation of the Hamiltonian with respect to the field operators. Also, equations for the development of matrix elements (underlying Green’s functions) are derived using variations with respect to particle and potential “sources” (and coupling strength). Variational calculus, involving impressed potentials, c-number coordinates and fields, also quantum operator coordinates and fields, is discussed in full detail. Attention is given to the introduction of fermion and boson particle sources and their use in variational calculus.

Full textAbstract:
Chapter 25 introduced some basic generic principles applicable to many measurement and monitoring techniques. Chapter 43 introduces those principles not covered in Chapter 25 and discusses in detail the clinical applications and limitations of the many monitoring techniques available to the modern clinical anaesthetist. It starts with non-invasive blood pressure measurement, including clinical and automated techniques. This is followed by techniques of direct blood pressure measurement, noting that transducers and calibration have been discussed in Chapter 25. This is followed by electrocardiography. There then follows a section on the different methods of measuring cardiac output, including the pulmonary artery catheter, the application of ultrasound in echocardiography, pulse contour analysis (LiDCO™ and PiCCO™), and transthoracic electrical impedance. Pulse oximetry is then discussed in some detail. Depth of anaesthesia monitoring is then described, starting with the electroencephalogram and its application in BIS™ monitors, the use of evoked potentials, and entropy. There then follow sections on gas pressure measurement in cylinders and in breathing systems, followed by gas volume and flow measurement, including the rotameter, spirometry, and the pneumotachograph, and the measurement of lung dead space and functional residual capacity using body plethysmography and dilution techniques. The final section is on respiratory gas analysis, starting with light refractometry as the standard against which other techniques are compared, infrared spectroscopy, mass spectrometry, and Raman spectroscopy (the principles of these techniques having been introduced in Chapter 25), piezoelectric and paramagnetic analysers, polarography and fuel cells, and blood gas analysis.

Full textAbstract:
About one American in five receives a diagnosis of major depression over the course of a lifetime. That's despite the fact that many such patients have no mood disorder; they're not sad, but suffer from anxiety, fatigue, insomnia, or a tendency to obsess about the whole business. "There is a term for what they have," writes Edward Shorter, "and it's a good old-fashioned term that has gone out of use. They have nerves." In How Everyone Became Depressed, Edward Shorter, a distinguished professor of psychiatry and the history of medicine argues for a return to the old fashioned concept of nervous illness. These are, he writes, diseases of the entire body, not the mind, and as was recognized as early as the 1600s. Shorter traces the evolution of the concept of "nerves" and the "nervous breakdown" in western medical thought. He points to a great paradigm shift in the first third of the twentieth century, driven especially by Freud, that transferred behavioral disorders from neurology to psychiatry, spotlighting the mind, not the body. The catch-all term "depression" now applies to virtually everything, "a jumble of non-disease entities, created by political infighting within psychiatry, by competitive struggles in the pharmaceutical industry, and by the whimsy of the regulators." Depression is a real and very serious illness, he argues; it should not be diagnosed so promiscuously, and certainly not without regard to the rest of the body. Meloncholia, he writes, "the quintessence of the nervous breakdown, reaches deep into the endocrine system, which governs the thyroid and adrenal glands among other organs." In a learned yet provocative challenge to psychiatry, Shorter argues that the continuing misuse of "depression" represents nothing less than "the failure of the scientific imagination."

Nicotine itself has some adverse physiological effects but it is mainly the 4000+ chemicals (including acetone, arsenic, paint stripper, pesticides, and over 60 known carcinogens), added to make the cigarette such an extremely potent nicotine delivery device, that cause so much damage.A smoker dies on average 8–10 years before a non-smoker does. The commonest causes of premature death in smokers are cardiovascular disease, lung cancer, and COPD. However, smoking also leads to much morbidity, causing or worsening many illnesses and affecting every system of the body. In addition, it is associated with a number of cancers, including lung cancer, nasopharyngeal cancer, laryngeal cancer, oesophageal cancer, stomach cancer, pancreatic cancer, colonic cancer, kidney cancer, bladder cancer, cervical cancer, and acute myeloid leukaemia. Stopping smoking at any age has been shown to improve health and increase life expectancy. Even with advanced smoking-related diseases, observational studies show clinically meaningful benefits in stopping smoking.

Full textAbstract:
For more than 2000 years Greek philosophers have thought about the puzzling introspectively assessed dichotomy between our physical bodies and our seemingly non-physical minds. How is it that we can think highly abstract thoughts, seemingly fully detached from actual, physical reality? Despite the obvious interactions between mind and body (we get tired, we are hungry, we stay up late despite being tired, etc.), until today it remains puzzling how our mind controls our body, and vice versa, how our body shapes our mind. Despite a big movement towards embodied cognitive science over the last 20 years or so, introductory books with a functional and computational perspective on how human thought and language capabilities may actually have come about – and are coming about over and over again – are missing. This book fills that gap. Starting with a historical background on traditional cognitive science and resulting fundamental challenges that have not been resolved, embodied cognitive science is introduced and its implications for how human minds have come and continue to come into being are detailed. In particular, the book shows that evolution has produced biological bodies that provide “morphologically intelligent” structures, which foster the development of suitable behavioral and cognitive capabilities. While these capabilities can be modified and optimized given positive and negative reward as feedback, to reach abstract cognitive capabilities, evolution has furthermore produced particular anticipatory control-oriented mechanisms, which cause the development of particular types of predictive encodings, modularizations, and abstractions. Coupled with an embodied motivational system, versatile, goal-directed, self-motivated behavior, learning becomes possible. These lines of thought are introduced and detailed from interdisciplinary, evolutionary, ontogenetic, reinforcement learning, and anticipatory predictive encoding perspectives in the first part of the book. A short excursus then provides an introduction to neuroscience, including general knowledge about brain anatomy, and basic neural and brain functionality, as well as the main research methodologies. With reference to this knowledge, the subsequent chapters then focus on how the human brain manages to develop abstract thought and language. Sensory systems, motor systems, and their predictive, control-oriented interactions are detailed from a functional and computational perspective. Bayesian information processing is introduced along these lines as are generative models. Moreover, it is shown how particular modularizations can develop. When control and attention come into play, these structures develop also dependent on the available motor capabilities. Vice versa, the development of more versatile motor capabilities depends on structural development. Event-oriented abstractions enable conceptualizations and behavioral compositions, paving the path towards abstract thought and language. Also evolutionary drives towards social interactions play a crucial role. Based on the developing sensorimotor- and socially-grounded structures, the human mind becomes language ready. The development of language in each human child then further facilitates the self-motivated generation of abstract, compositional, highly flexible thought about the present, past, and future, as well as about others. In conclusion, the book gives an overview over how the human mind comes into being – sketching out a developmental pathway towards the mastery of abstract and reflective thought, while detailing the critical body and neural functionalities, and computational mechanisms, which enable this development.

This monograph presents recent advances in neural network (NN) approaches and applications to chemical reaction dynamics. Topics covered include: (i) the development of ab initio potential-energy surfaces (PES) for complex multichannel systems using modified novelty sampling and feedforward NNs; (ii) methods for sampling the configuration space of critical importance, such as trajectory and novelty sampling methods and gradient fitting methods; (iii) parametrization of interatomic potential functions using a genetic algorithm accelerated with a NN; (iv) parametrization of analytic interatomic potential functions using NNs; (v) self-starting methods for obtaining analytic PES from ab inito electronic structure calculations using direct dynamics; (vi) development of a novel method, namely, combined function derivative approximation (CFDA) for simultaneous fitting of a PES and its corresponding force fields using feedforward neural networks; (vii) development of generalized PES using many-body expansions, NNs, and moiety energy approximations; (viii) NN methods for data analysis, reaction probabilities, and statistical error reduction in chemical reaction dynamics; (ix) accurate prediction of higher-level electronic structure energies (e.g. MP4 or higher) for large databases using NNs, lower-level (Hartree-Fock) energies, and small subsets of the higher-energy database; and finally (x) illustrative examples of NN applications to chemical reaction dynamics of increasing complexity starting from simple near equilibrium structures (vibrational state studies) to more complex non-adiabatic reactions. The monograph is prepared by an interdisciplinary group of researchers working as a team for nearly two decades at Oklahoma State University, Stillwater, OK with expertise in gas phase reaction dynamics; neural networks; various aspects of MD and Monte Carlo (MC) simulations of nanometric cutting, tribology, and material properties at nanoscale; scaling laws from atomistic to continuum; and neural networks applications to chemical reaction dynamics. It is anticipated that this emerging field of NN in chemical reaction dynamics will play an increasingly important role in MD, MC, and quantum mechanical studies in the years to come.
