Abstract (sommario):

Reversibility is a mental process to construct two-way correlation from an initial condition to the result, and from result reverse to initial state. The concept of reversibility is a key aspect of the development of mathematics which is often problema for student. Reversible thinking is the primary requirement to solve mathematical problems. The importance of reversibility is one of the reasons in this study. The aimed of this study was to identify student’s reversibility in solving algebaic problems. The subject consisted of 32 junior high school student’s, especially at the eight grade. In this qualitative study, data were collected by a reversibility task and interview. The reversibility task contained simple equation. The result of this study indicate that reversibility aspect of solving algebaic problem can identified were reciprocity and negation, in this case reciprocity was more prominent. This could be seen from 32 junior high school students were able to make equation according to the reversibility aspect, but there were only five students are be able to fulfill two aspect of reversibility, described as negation and reciprocity, the others only fill reciprocity. The result showed that the problem related reversibility on junior high school still exist, especially in the aspect of negation.

Abstract (sommario):

This work simulates reversibility of plane waves in different ways. We start making theoretical classical reversing of a plane wave in two different ways exchanging t by –t as first step. In one case, we additionally flip the temporal orientation of the magnetic field. In the other case, we flip the electric field. Therefore, we can compare two classical approaches to time reversed electromagnetism on plane waves. On the other hand, we obtain two different mechanically reversed plane electromagnetic waves out of the frame of the electromagnetics reversibility theory. A theoretical experiment makes these effects, where, an infinite plane current generates two plane waves in opposite directions. After this, the waves are made to return by two different ways: (1) by retro reflecting and (2) by moving back the wave. Finally, the returning plane waves insides over a conductor plane in order to induce plane currents in the conductor. The goal is to complete reversibility cycles including the charges movement. The returning waves and the induced currents will be compared themselves in all the cases. Charges movements are also included in the discussion in order to have an additional felling of the waves reversibility and physical insight of time-reversed waves. It is used a plane waves theoretical experiment created by Feynman as a starting point [1]

Abstract (sommario):

Thesis (Ph.D.)--Massachusetts Institute of Technology, Dept. of Electrical Engineering and Computer Science, 1999.
Includes bibliographical references (p. 391-405).
Today's computers are based on irreversible logic devices, which have been known to be fundamentally energy-inefficient for several decades. Recently, alternative reversible logic technologies have improved rapidly, and are now becoming practical. In traditional models of computation, pure reversibility seems to decrease overall computational efficiency; I provide a proof to this effect. However, traditional models ignore important physical constraints on information processing. This thesis gives the first analysis demonstrating that in a realistic model of computation that accounts for thermodynamic issues, as well as other physical constraints, the judicious use of reversible computing can strictly increase asymptotic computational efficiency, as machine sizes increase. I project real benefits for supercomputing at a large (but achievable) scale in the fairly near term. And with proposed future computing technologies, I show that reversibility will benefit computing at all scales. Next, the thesis demonstrates that reversible computing techniques do not make computer design much more difficult. I describe how to design asymptotically efficient processors using an "adiabatic" reversible electronic logic technology that can be built with today's microprocessor fabrication processes. I describe a simple universal reversible parallel processor chip that our group recently fabricated, and a reversible instruction set for a more traditional RISC-style uniprocessor. Finally, I describe techniques for programming reversible computers. I present a high-level language and a compiler suitable for coding efficient reversible algorithms, and I describe a variety of example algorithms, including efficient reversible sorting, searching, arithmetic, matrix, and graph algorithms. As an example application, I present a linear-time, constant-space reversible program for simulating the Schrodinger wave equation of quantum mechanics.

Abstract (sommario):

Heterozygous and recently identified homozygous mutations in the SPTBN2 gene, encoding b-III spectrin, are implicated in spinocerebellar ataxia type 5 (SCA5) and spectrin-associated autosomal recessive cerebellar ataxia type 1 (SPARCA1), respectively. Our mouse model, lacking b-III spectrin (KO), mimics the progressive human phenotype displaying motor deficiencies as well as reduced Purkinje cell firing frequency followed by dendritic tree degeneration and cell death. The aims of this study were to evaluate progression of Purkinje cell degeneration following loss of b-III spectrin function and determine whether the reintroduction of C-terminus (C-trm) of b-III spectrin to the cerebellum is enough to halt, alleviate or reverse the disease phenotype. Additionally, this study investigated whether the abnormal electrophysiological and morphological phenotypes of Purkinje cells from KO mice are re-capitulated in a primary cerebellar culture and if so, whether they could be rescued by modulating calcium signaling. Morphological and histological analyses revealed that Purkinje cell degeneration is not uniform throughout the cerebellum of KO mice with Purkinje cells from posterior cerebellar regions possessing significantly smaller dendritic trees when compared to anterior cerebellum (p=0.0003, N=4-6, n=11-29). Similarly, significant reduction in Purkinje cell density was observed in posterior, not anterior regions of KO mice when compared to WT animals (p=0.014, N=3) and reduced tonic firing is most significant in Purkinje cells from the posterior cerebellum compared to WT mice (p=0.0328, N=3-6, n=11-29), with posterior KO PCs appearing to have elevated input resistance. Two-week expression of C-trm b-III spectrin in 3-month old KO animals significantly reduced Purkinje cell input resistance when compared to non-transduced cells (p=0.0139, N=4-5, n=15), but no effect was seen 9 months after viral injection. In contrast, a difference in cell surface area was no longer detected between WT and KO animals at 12 months of age following 9-months of viral expression. Nevertheless, using the elevated beam test motor deterioration was still observed 5 months after surgery (p=0.0023, N=4). In contrast, earlier stereotaxic injections at 6-weeks of age had a positive effect on mice motor performance with no deterioration in performance detected 5 months after the surgery. Latency to stay on the rotarod at 3 rpm was also significantly extended 6 months after stereotaxic injections at 6-weeks of age with slower motor deterioration (p=0.0348, N=6). In primary cerebellar cultures, Purkinje cells from KO animals exhibit an abnormal morphology with significantly more dendritic branches (p < 0.0001, N=4-7, n=35-69) and a larger total dendritic length (p=0.0079). Chronic application of 2 μM mibefradil, a T-type calcium channel blocker, was observed to reduce total dendritic length and branching in KO animal cultures bringing these morphological measurements closer to WT Purkinje cell levels. Finally although after 14 days in vitro 40% of Purkinje cells were found to be spontaneously firing, no significant difference in firing frequency (p=0.9434) or input resistance (p=0.8434, N=4, n=6-10) was detectable between WT and KO cultures. In summary, Purkinje cells in posterior cerebellar regions of KO mice were found to be more susceptible to dendritic degeneration and cellular death than cells in the anterior cerebellum. Expression of C-trm b-III spectrin at 3 months of age had an immediate effect on cell input resistance and a modest effect on Purkinje cell morphology but no effect on motor decline. Viral injections at 6-weeks of age, however, significantly slowed motor decline. Although an abnormal KO cell morphology could be successfully recapitulated in primary cell culture, it was not possible to discern any differences in electrophysiological properties. Nevertheless, the abnormal cell morphology was successfully modified in vitro by manipulating calcium signaling via T-type calcium channels.

Abstract (sommario):

Assessing the performance and reliability of computer and telecommunication systems requires the development of stochastic models whose state space are very large. This problem is often known as "State Space Explosion". As a consequence, general purpose algorithms for their solution cannot be applied straightforwardly. This problem may be found both at continuous or discrete time. To tackle this problem we resorted to the theory of product-forms, including the latest theoretical developments in the field such as the Reversed Compound Agents Theorem (RCAT) and new forms of time-reversibility. The main contribution of our work consists in the identification of classes of product-form models that are not captured by previous results. More specifically, our contribution can be summarized as follows: - We identified a process algebraic specification of models including instantaneous propagation of signals at continuous time such as those required to describe the G-networks with negative customers and triggers. As an application of this result we introduced an original model which allows one to perform an exact analysis for a class of cache systems based on the policy Time-To-Live (TTL) with resets. - We characterized a class of models suitable for the quantitative analysis of reversible computations. We showed that our results can be useful for the performance evaluation of speculative distributed simulations. - Finally, we analysed product-form models also at discrete time and provided a product-form formulation for the Probabilistic Input/Output Automata (PIOA).

Abstract (sommario):

The incidence of both obesity and type 2 diabetes continues to rise, creating a major worldwide public health challenge. Understanding the mechanisms determining the normalisation of blood glucose levels and the limitations to complete reversal of diabetes by bariatric surgery or a very low calorie diet (VLCD) has important implications for the treatment of type 2 diabetes, but also for improving our understanding of the pathophysiology. A unifying hypothesis to explain the major pathophysiological changes in type 2 diabetes, hepatic insulin resistance and pancreatic beta cell insufficiency, involves excess triglyceride accumulation in liver and pancreas. This is supported by in vitro demonstration of impaired insulin signalling (and thereby insulin resistance) and defective insulin secretion, induced by the toxic metabolites of fat. Triglyceride content in liver and pancreas can now be measured non-invasively and precisely using the three point Dixon magnetic resonance technique. This thesis presents data on a direct comparison of bariatric surgery and VLCD, suggesting that the mechanisms involved in the reversibility of type 2 diabetes using these two interventions are similar. Pancreatic triglyceride content appears to decrease with substantial weight loss in obese individuals with type 2 diabetes but not those with normal glucose tolerance. The clinical characteristics which limit reversal of diabetes are investigated, particularly the effect of longer diabetes duration. Both a retrospective study of bariatric surgery and a prospective study using VLCD suggest that long duration diabetes is reversible, however, normal blood glucose levels are less likely to be achieved than in short duration disease. Diabetes duration may be a surrogate marker for beta cell reserve. Finally, the longer term durability of the beneficial effects of an 8 week very low calorie diet is demonstrated. Over a subsequent 6 month weight maintenance period the decrease in hepatic and pancreatic triglyceride content, and the improvements in hepatic insulin sensitivity and first phase insulin secretion are maintained. The latter appears to be a key mechanism for determining a glucose response to VLCD.

Binger, Katrina Jean. "The reversibility of amyloid fibril formation". Connect to thesis, 2009. http://repository.unimelb.edu.au/10187/4912.

Testo completo

Abstract (sommario):

The aggregation of misfolded proteins into amyloid fibrils is implicated in the pathogenesis of several human degenerative diseases, including Alzheimer’s, Parkinson’s and Type II diabetes. Links between the deposition of amyloid fibrils and the progression of these diseases are poorly understood, with much of the current research focused on monomer misfolding and subsequent assembly of oligomers and mature fibrils. This project examines the formation of human apolipoprotein (apo) C-II amyloid fibrils, with a focus on the stability and reversibility of amyloid fibril assembly.
The initial stages of the project were to develop a model for apoC-II amyloid fibril formation. This was achieved by analysis of the concentration dependent kinetics of apoC-II amyloid fibril formation, and correlation of these data with the final size distribution of the fibrils, determined by sedimentation velocity experiments. On the basis of these studies, a new reversible model for apoC-II amyloid fibril formation is proposed that includes fibril breaking and re-joining as integral parts of the assembly mechanism. The model was tested by rigorous experimentation, with antibody-labelling transmission electron microscopy providing direct evidence for spontaneous fibril breaking and re-joining.
The development of this model for apoC-II fibril assembly provided the foundation for experiments to investigate factors that promote, inhibit or reverse amyloid fibril formation. Factors that were considered include a molecular chaperone protein, αB-crystallin, and a chemical modification, methionine oxidation. Investigations on the effect of αB-crystallin revealed that the inhibition of apoC-II fibril formation occurs by two distinct mechanisms: transient interaction with monomer preventing oligomerisation, and binding to mature fibrils, which inhibits fibril elongation. Studies on the effect of methionine oxidation on apoC-II fibril formation showed that both the assembly and stability of the fibrils was affected by this modification. ApoC-II contains two methionine residues (Met-9 and Met-60), and upon oxidation of these residues fibril formation was inhibited. In addition, the treatment of pre-formed fibrils with hydrogen peroxide caused dissociation of the fibrils via the oxidation of Met-60, located with the fibril core structural region. The final chapter details the development of antibodies that specifically recognise the conformation of apoC-II amyloid fibrils, which provide the foundation for future studies to examine the role that apoC-II amyloid fibrils play in disease.
Overall, this thesis reveals the dynamic and reversible nature of amyloid fibril formation. New insight is also obtained of the general stability of amyloid fibrils and the processes that may regulate their formation, persistence and disease pathogenesis in vivo.

Abstract (sommario):

The problem of action reversibility studies whether effects of a given action can be reversed (or undone) by a sequence of (other) actions. For example, actions whose effects can be reversed cannot lead to dead-ends. In the usual settings, the problem of action reversibility is PSPACE-complete, that is, as hard as deciding plan existence. In this paper, we focus on subclasses of the action reversibility problem, universal and uniform action reversibility, where the former considers all states in which the action in question is applicable, while the latter requires a single reverting action sequence, independent of the considered states. Specifically, we study the relations between projection abstractions and the subclasses of the action reversibility problem and we show that universal uniform reversibility of a given action can be decided on projection consisting of only the variables present in the schema of the action in question.

Abstract (sommario):

In cyclographic modeling of lines of space R3 direct and inverse problems and their solutions are known. In addition to the classic cyclographic projection, there is modified cyclographic projection of a line of space, developed on the basis of the classic one. The modified cyclographic projection has practical relevance in design of general purpose road surface forms. For this projection, the solution of the direct problem, i.e. to determine modified cyclographic projection given a curve of space (road axis), is known. In this paper, we propose a solution to the inverse problem - to restore the initial space curve given its modified cyclographic projection. The paper provides justification for solution to the inverse problem and considers on example an analytic solution to the inverse problem given second-order curves. The results of this study can be applied as the basis for development of computer-aided design systems for road surface forms, both in creation of new working surface forms, and in restoration the existing ones.

Abstract (sommario):

Output reversibility involves dynamical systems where for every initial condition and the corresponding output there exists another initial condition such that the output generated by this initial condition is a time-reversed image of the original output with the time running forward. Through a series of necessary and sufficient conditions, we characterize output reversibility in linear single-output discrete-time dynamical systems in terms of the geometric symmetry of its eigenvalue set with respect to the unit circle in the complex plane. Furthermore, we establish that output reversibility of a linear continuous-time system implies output reversibility of its discretization regardless of the sampling rate. Finally, we present a numerical example involving a discretization of a Hamiltonian system that exhibits output reversibility.

Abstract (sommario):

The paper critically examines the New Keynesian explanation of hysteresis based on the role of long-term unemployment. We first examine its analytical foundations, according to which rehiring long-term unemployed individuals would not be possible without accelerating inflation. Then we empirically assess its validity along two lines of inquiry. First, we investigate the reversibility of long-term unemployment. Then we focus on episodes of sustained long-term unemployment reductions to check for inflationary effects. Specifically, in a panel of 25 OECD countries (from 1983 to 2016), we verify by means of local projections whether they are associated with inflationary pressures in a subsequent five-year window. Two main results emerge: i) the evolution of the long-term unemployment rate is almost completely synchronous with the dynamics of the total unemployment rate, both during downswings and upswings; ii) we do not find indications of accelerating or persistently higher inflation during and after episodes of strong declines in the long-term unemployment rate, even when they occur in country-years in which the actual unemployment rate was estimated to be below a conventionally estimated Non-Accelerating Inflation Rate of Unemployment (NAIRU). Our results call into question the role of long-term unemployment in causing hysteresis and provide support to policy implications that are at variance with the conventional wisdom that regards the NAIRU as an inflationary barrier.

Abstract (sommario):

This research project introduced a novel membrane coating strategy to combat biofouling, which is a major problem for the membrane-based treatment of agricultural and municipal wastewaters. The novelty of the strategy is that the membrane coatings have the unique ability to switch reversibly between passive (antifouling) and active (antimicrobial) fouling control mechanisms. This dual-mode approach differs fundamentally from other coating strategies that rely solely on one mode of fouling control. The research project had two complementary objectives: (1) preparation, characterization, and testing of dual-mode polymer nanolayers on planar surfaces and (2) evaluation of these nanolayers as membrane modifiers. The first objective was designed to provide a fundamental understanding of how polymer nanolayer chemistry and structure affect bacterial deposition and to demonstrate the reversibility of chemical switching. The second objective, which focused on membrane development, characterization, and testing, was designed to demonstrate methods for the production of water treatment membranes that couple passive and active biofouling control mechanisms. Both objectives were attained through synergistic collaboration among the three research groups. Using planar silicon and glass surfaces, we demonstrated using infrared spectroscopy that this new polymer coating can switch reversibly between the anti-fouling, zwitterion mode and an anti-microbial, quaternary amine mode. We showed that switching could be done more than 50 times without loss of activity and that the kinetics for switching from a low fouling zwitterion surface to an antimicrobial quaternary amine surface is practical for use. While a low pH was required for switching in the original polymer, we illustrated that by slightly altering the chemistry, it is possible to adjust the pH at which the switching occurs. A method was developed for applying the new zwitterionic surface chemistry onto polyethersulfone (PES) ultrafiltration membranes. Bacteria deposition studies showed that the new chemistry performed better than other common anti-fouling chemistries. Biofilm studies showed that PESultrafiltration membranes coated with the new chemistry accumulated half the biomass volume as unmodified membranes. Biofilm studies also showed that PES membranes coated with the new chemistry in the anti-microbial mode attained higher biofilm mortality than PES membranes coated with a common, non-switchablezwitterionic polymer. Results from our research are expected to improve membrane performance for the purification of wastewaters prior to use in irrigation. Since reduction in flux due to biofouling is one of the largest costs associated with membrane processes in water treatment, using dual-mode nanolayer coatings that switch between passive and active control of biofouling and enable detachment of attached biofoulants would have significant economic and societal impacts. Specifically, this research program developed and tested advanced ultrafiltration membranes for the treatment of wastewaters. Such membranes could find use in membrane bioreactors treating municipal wastewater, a slightly upgraded version of what presently is used in Israel for irrigation. They also may find use for pretreatment of agricultural wastewaters, e.g., rendering facility wastewater, prior to reverse osmosis for desalination. The need to desalinate such impaired waters water for unlimited agricultural use is likely in the near future.
