description: We investigate the upper mass limit predictions of the baryonic mass for static neutron stars in the context of $f(R)$ gravity. We use the most popular $f(R)$ gravity model, namely the $R^2$ gravity, and calculate the maximum baryon mass of static neutron stars adopting several realistic equations of state and one ideal equation of state, namely that of causal limit. Our motivation is based on the fact that neutron stars with baryon masses larger than the maximum mass for static neutron star configurations inevitably collapse to black holes. Thus with our analysis, we want further to enlighten the predictions for the maximum baryon masses of static neutron stars in $R^2$ gravity, which, in turn, further strengthens our understanding of the mysterious mass-gap region. As we show, the baryon masses of most of the equations of states studied in this paper, lie in the lower limits of the mass-gap region $M\sim 2.5-5 M_{\odot}$, but intriguingly enough, the highest value of the maximum baryon masses we found is of the order of $M\sim 3 M_{\odot}$. This upper mass limit also appears as a maximum static neutron star gravitational mass limit in other contexts. Combining the two results which refer to baryon and gravitational masses, we point out that the gravitational mass of static neutron stars cannot be larger than three solar masses, while based on maximum baryon masses results of the present work, we can conspicuously state that it is highly likely the lower mass limits of astrophysical black holes in the range of $M\sim 2.5-3 M_{\odot}$. This, in turn, implies that maximum neutron star masses in the context of $R^2$ gravity are likely to be in the lower limits of the range of $M\sim 2.4-3 M_{\odot}$. Hence our work further supports the General Relativity claim that neutron stars cannot have gravitational masses larger than $3$$M_{\odot}$.

description: Explicit time-dependent solutions of the 10D vacuum Einstein equations are found for which spacetime is compactified on six-dimensional warped spaces. We explicitly work out an example where the internal manifold is a six-dimensional generalized space having positive, negative or zero scalar curvature, whose base can be a five-sphere $S^5$ or an Einstein space $T^{1,1}=(S^2\times S^2)\rtimes S^1$. In this paper, inflationary de Sitter solutions are found just by solving the 10D vacuum Einstein equations. Our results further show that the limitation with warped models studied to date has arisen partly from an oversimplification of the 10D metric ansatz. We also give some explicit examples of a non-singular warped compactification on de Sitter space dS$_4$.

title: Oxidation of Thin Silver Films by Ozone and Atomic Oxygen
Creators: name: Thorne, Lawrence R.
Publisher: name: Utah State University
Year: 1973

description: Recently, thin silver film detectors have been used to determine atomic oxygen profiles in the 70-100 km region of the upper atmosphere. The detectors' sensitivity to atomic oxygen is the result of the formation of silver oxide(s) which cause their electrical resistance to increase. A common procedure to calibrate and to make these detectors more sensitive is to cycle them through a series of three or more oxidations and reductions. This paper indicates that this cycling makes silver films more sensitive to ozone, causing them to be usable only at heights greater than 38 km. Also reported herein are experimentally determined sticking coefficients for atomic oxygen and ozone on a cycled silver surface as being 2.8 x 10-2 and 5 x 10-5 , respectively.
In an attempt to understand better the nature of the oxidation of silver by ozone and atomic oxygen, the proposed kinetics of these two reactions are reviewed, and supporting evidence for a previously proposed model reported.

title: Measurement of Soil Water Potential by Adsorption Conductivity
Creators: name: Rasmussen, V. Philip
Publisher: name: Utah State University
Year: 1974

description: Current methods of measuring soil water potential are reviewed, and the limitations of each are noted. The need for a transducer that will measure soil water potential over a wide moisture range for long periods of time is delineated. The concept of utilizing an adsorptive surface that resembles the soil in its water holding capacity as a transducer is discussed. Various designs and materials are tested for such a transducer.
All designs tested did not fulfill the requirements needed for a truly useful transducer. However, experimental results show that modification of the adsorptive surface should allow construction of a unit that will be useful in soil water research.
Primordial Black Holes And Gravitational Waves Based On No-Scale Supergravity

description: In this paper we present a class of models in order to explain the production of Primordial Black Holes (PBHs) and Gravitational Waves (GWs) in the Universe. These models are based on no-scale theory. By breaking the SU(2,1)/SU(2)$\times$U(1) symmetry we fix one of the two chiral fields and we derive effective scalar potentials which are capable of generating PBHs and GWs. As it is known in the literature there is an important unification of the no-scale models, which leads to the Starobinsky effective scalar potential based on the coset SU(2,1)/SU(2)$\times$U(1). We use this unification in order to additionally explain the generation of PBHs and GWs. Concretely, we modify well-known superpotentials, which reduce to Starobinsky-like effective scalar potentials. Thus, we derive scalar potentials which, on the one hand, explain the production of PBHs and GWs and, on the other hand, they conserve the transformation laws, which yield from the parametrization of the coset SU(2,1)/SU(2)$\times$U(1) as well as the unification between the models which are yielded this coset. We numerically evaluate the scalar power spectra with the effective scalar potential based on this theory. Furthermore, we evaluate the fractional abundances of PBHs by comparing two methods the Press-Schechter approach and the peak theory, while focusing on explaining the dark matter in the Universe. By using the resulting scalar power spectrum we evaluate the amount of GWs. All models are in complete consistence with Planck constraints.

title: Osiris, God of Ancient Egypt and A Brief Background of Egyptian Mythology
Creators: name: Pendleton, Carol
Publisher: name: Utah State University
Year: 1972

description: In a country which has been subjected to so many inflows of various peoples, languages, and cultural patterns as has Egypt, one may expect to find a great diversity of deities and a complex and inconsistent theology. To differentiate the principal gods is the first step toward understanding the growth of the Egyptian religion. For in instances where polytheism can be traced back to its earliest stages we find that it usually has developed from a combination of monotheistic beliefs. It is improbable to suppose that a people would unite two gods, both of which belonged to them originally; there would be no reason for two similar gods in a single system, for example, we never hear in classical mythology of Hermes-Apollo or Pallas-Artemis, or Zeus, compounded with half of the barbarian gods of Asia. So in Egypt, when we find such compounds as Amon-Ra, or Ptah-Shahar-Osiris, we can assume that each name in the compound is derived from a different tribe of people, and that a unifying operation has taken place on gods that belonged to entirely different sources.
Entanglement generation with a quantum channel and a shared state

description: We introduce a new protocol, the channel-state coding protocol, to quantum Shannon theory. This protocol generates entanglement between a sender and receiver by coding for a noisy quantum channel with the aid of a noisy shared state. The mother and father protocols arise as special cases of the channel-state coding protocol, where the channel is noiseless or the state is a noiseless maximally entangled state, respectively. The channel-state coding protocol paves the way for formulating entanglement-assisted quantum error-correcting codes that are robust to noise in shared entanglement. Finally, the channel-state coding protocol leads to a Smith-Yard superactivation, where we can generate entanglement using a zero-capacity erasure channel and a non-distillable bound entangled state.

The very-extended trombone

description: Starting from the very-extended Kac-Moody algebra $E_{11}$, we consider the algebra $E_{11,D}^{local}$, obtained by adding to the non-negative level $E_{11}$ generators the $D$-dimensional momentum operator and an infinite set of additional generators that promote the global $E_{11}$ symmetries to gauge ones. We determine all the possible trombone deformations of this algebra, that is the deformations that involve the $D$-dimensional scaling operator. The Jacobi identities imply that such deformations are uniquely determined by a single tensor belonging to the same representation of the internal symmetry group as the vector generators and satisfying additional quadratic constraints. The non-linear realisation of the deformed algebra gives the field strengths of the theory which are those of any possible maximal supergravity theory in which the global scaling symmetry is gauged in any dimension. All the possible deformed algebras are in one to one correspondence with all such maximal supergravity theories. The tensor that parametrises the deformation is identified with the embedding tensor that is used to parametrise all maximal supergravity theories with gauged scaling symmetry, and the quadratic constraints that we determine exactly coincide with the field theory results.

title: Summary of Efforts to Increase Sales Tax by 1/2%
Creators: name: Anderson, Gary N
Publisher: name: Utah State University
Year: 1971

description: The 39th Legislature was faced with a well-organized lobby promoting the adoption of an increase in the sales tax to help the cities of the State of Utah meet their increasing financial plight, particularly in financing the needs of law enforcement. This paper will outline, from an observer's viewpoint, the background of this movement; its initial approaches; its later attempts; and finally its failure.
This is an examination of one particular issue which contains several elements which have continuing significance. 1)The move to adopt the 1/2% sales tax was well-publicized and was quite visible to the public. 2)It had widespread significance because of its connection with the well-known problems of the cities. 3)It involved several different interest groups in pursuit of a common solution. 4)It provided a situation in which the activities of the various lobbyists were rather obvious. Most of these elements do not lend themselves to final conclusions and so they are merely discussed. However, one which is a little easier to evaluate is the effectiveness of the lobbying. Certain conclusion about this will be drawn.
One final explanation should be made. I was involved in the 39th Legislature as a legislative assistant to the President of the Senate. Although an effort was made to maintain objectivity, certain biases may make themselves apparent to the reader. Hopefully, these biases will not be significant enough to destroy the validity of this approach.
title: The Effect of British Intrusion on the Customary Law of Bantu Africa
Creators: name: Curtoys, C. Jeremy
Publisher: name: Utah State University
Year: 1971

description: Western man has great pride in his political institutions, which with some justification he holds to be the first to recognize the rule of law as superior to the rule of men. Thus it was with great confidence in his laws and rectitude of his ways that the first Europeans occupied Africa. The impact of this invasion upon the indigenous populations of Africa was tremendous. Every facet of Africa life, its social, political, economic and legal systems were affected.
A study of Bantu customary law has to depend largely on secondary material, because until recent times, the law of Bantu Africa was largely unwritten. A number of monographs has been written by anthropologists in the field, but few of them give more than a chapter to an examination of the laws and their power of sanction as exercised by the courts. Yet it is the courts that are the precursors of legislation, and ultimately, legislation is the province of the state. "it was the court really that launched the 'state' for it was in the court that the sentiment of etatism, with all its devotion and loyalties, was first nurtured."
James Britton’s theory of language and learning and the recent ’affective’ literary critics
Creators: name: McBurney, Robert Philip
Publisher: name: University of British Columbia
Year: 2010

description: This thesis examines the theories of some recent affective* literary critics in the light of James Britton's theory of language and learning. Until recently, literary criticism generally has not been concerned with the relationship between the text and the reader; it has concerned itself either with the poem as a static verbal object, as in New Criticism, or with the writer-text relationship, as in biographical criticism. With the neglect of the text-reader relationship, the study of literature has also ignored a basic aesthetic principle -- that the relationship between a work of art and its percipient is a dynamic interaction where 'ordinary' experience cannot be separated from aesthetic experience. Chapter I delineates this principle proposed primarily by John Dewey, whose theory is complemented by those of R.G. Collingwood, Susanne Langer, and George Kelly. Chapter II identifies and examines the recent theories of seven literary critics who discuss the 'affective' relationship between the reader and the text -- Norman Holland, Standly Fish, Roland Barthes, Wolfgang Iser, Georges Poulet, Wayne Booth, and Walter Slatoff. Two ideas emerge which are related to the aesthetic principle espoused by John Dewey and others: 1) our aesthetic responses to literature are natural extensions of our mundane selves; and 2) literature as art is still a linguistic utterance, and as such is related to other ordinary kinds of language use. But these ideas are rudimentary and fragmented and there is a need for a more general theory to integrate them. James Britton's theory of language in Chapter III, contained mainly in his book Language and Learning, provides a structure which subsumes these fragmented ideas so that a perspective can be gained on this new criticism. Britton puts forth the view that literature is a manifestation of man's linguistic activity in what he calls the 'spectator role*. This theory integrates the critical ideas arising out of Chapter II and also places literature in a new perspective with other of man's spectator role activities, both linguistic (gossip, personal letter-writing) and non-linguistic (play, dream, fantasy, ritual). Britton points to the importance of spectator role activities in personal development.

description: "Alienation, estrangement, disaffection, anomie, withdrawal, disengagement, separation, noninvolvement, apathy, indifference, and neutralism--all of these terms point to a sense of loss, a growing gap between men and their social world." but these terms, which Kenneth Keniston disparages as the current vocabulary of social commentary, are indeed a familiar description of today. The youth on college campuses are especially fluent in the use of the many synonyms of alienations to depict prevalent college attitudes and social values. Even the term "generation gap" seems to cry of separation, estrangement, and alienation between two factions of our society-- young and old. what is causing this sense of alienation in the new generation? Is the seeming obsession with breakdown, protest, destruction, and defiance against the "Establishment" causing deeper gulfs of separation between "them" and "us"; or are protest and violence only the climatic manifestations against the deeper, slowly evolving social attitude of estrangement and apathy? Which should be called alienation?

Creators: name: Carlsen, Lief
Publisher: name: Utah State University
Year: 1972

description: In an attempt to delineate the physiological and/or chemical nature of the memory process, some researchers have reported that by introducing all or part of the brain of a trained animal into the bloodstream of another animal, the recipient thereby "acquires a tendency" to respond as the donor was trained. However, almost as many researchers have failed to obtain significant results.
Because many of the early experiments had less than optimum designs, their results were often equivocal. Critics frequently pointed out that perhaps increased learning efficiency was due merely to a sensitizing or stimulating effect of the injection and not to any specific transfer of learning. It was in an attempt to answer this criticism that the following experiment was performed.

description: Since Parikh and Wilczek's tunneling method was proposed, there have been many generalizations, such as its application to massive charged particles' tunneling and other spacetimes. Moreover, a variant tunneling method was also recently proposed by Angheben et al that it was independent of coordinates. However, there are some subtleties in the calculation of Hawking radiation, and particularly is the so-called factor of 2 problem during calculating the Hawking temperature. The most popular opinion on this problem is that it is just a problem of the choice of coordinates. However, following other treatments we show that we can also consider this problem as a problem that we do not consider the contribution from P(absorption). Moreover, we also give some subtleties in the balance method and some comparisons with other treatments. In addition, as Parikh and Wilczek's original works have showed that if one takes the tunneling particles' back-reaction into account, the Hawking radiation would be modified, and this modification is underlying consistent with the unitary theory, we further find that this modification is also underlying correlated with the laws of black hole thermodynamics. Furthermore, we show that this tunneling method may be valid just when the tunneling process is reversible.

Variations of the Internal Asymmetries of Sunspot Groups During their Decay

description: The aim of the present study is to show the varying asymmetries during the decay of sunspot groups. The source of input data is the SoHO/MDI-Debrecen Database (SDD) sunspot catalog that contains the magnetic polarity data for time interval 1996-2010. Several types of asymmetries were examined on the selected sample of 142 sunspot groups. The leading-following asymmetry increases in three phases during the decay and exhibits anticorrelation with size. It is also related to a hemispheric asymmetry, during the decay the area asymmetry index has higher values in the southern hemisphere which may be due to the higher activity level in the southern hemisphere in cycle 23. The total umbral area is inversely proportional to the umbra/penumbra ratio but it is directly proportional to the umbral decay rate. During the decay the umbra/penumbra (U/P) ratio decreases unambiguously in the trailing parts but in most cases in the leading parts as well. The U/P variation is a consequence of the different depths of umbral and penumbral fields.

description: Democracy in America is often guided by the visible forces of the moment. Dangers are too often seen in the context of political interest--when fire is seen, the hoses of democratic action come wheeling out. But there is no excitement in smoke alone. The near constitutional crisis of the 1968 Presidential elections, (when the strong third party candidacy of George Wallace threatened to throw the election into the House of Representatives), caused a lot of smoke and a spark of flame. The alarm was sounded and the volunteer firemen from the halls of Congress and Capitol Hill responded. The standers-by, the self-made experts, the institutional geniuses, and the media-reporters-turned-commentators all clamored together in offerings of support and advice. Though the fire is cold embers now--the smoke still trails upward because the dry tinder remains tinder still.
The Founding Fathers were tempered by Locke's justification of revolution, by Cook's beliefs in constitutionalism, and Montesquieu's theory of separation of governmental powers when they wrote the Constitution. But in no particular did they take greater pride than in the device they invented for the election of a President. They views it as a means of peaceful, continual revolution and the essence and crowning glory of the system, done by peaceful assemblies, free discussion, and the ballot.
But the system, later to become known as the Electoral College, had flaws, and was, as Thomas Jefferson has said, "the most dangerous blot on our Constitution." Today it is called an oxcart method of selecting Space Age Presidents and suffers attacks from many quarters. But as the apparent fires abated, so too did the volunteer firemen. The vices and virtues of the system can now be studied, analyzed, and debated by cooler heads, and perhaps reason, not do-something-now-expediency will prevail. At a later date, when the complexities and variables have been studied and weighed and the reports are all in, maybe, just maybe, our volunteer firemen will rush into action as once before, this time armed with an effective, but safe tool to extract the tinder forever and replace it with non-flammables. But there is only smoke now--faintly visible and growing dimmer. It remains to be seen whether the firemen will rush into action before fire rises from the smoke once more.

The structure of spiral galaxies: radial profiles in stellar Mass-to-Light ratio and the Dark Matter distribution

description: The colour and metallicity gradients observed in spiral galaxies suggest that the mass-to-light ratio (M*/L) of the stellar disc is a function of radius. This is indeed predicted by chemo-photometric models of galactic discs. We investigate the distribution of luminous and dark matter in spiral galaxies, taking into account the radial dependence of the stellar M*/L - which is usually assumed to be constant in studies of the mass structure. From the chemo-photometric models of Portinari et al. (2004) and in agreement with the observed radial profiles of galaxy colours, we derive the typical average M*/L profile of the stellar discs of spiral galaxies. We compute the corresponding Variable Mass-to-Light (VML) stellar surface density profile and then the VML disc contribution to the circular velocity. We use the latter, combined with a well studied dark matter velocity profile, to mass model the co-added rotation curves of Persic et al. (1996). (See http://www.facebook.com/home.php#!/group.php?gid=310260450630 to retrieve extra information on the kinematics of galaxies) By investigating rotation curves in the framework of VML stellar discs, we confirm, to a first approximation, the scenario obtained with the constant M*/L assumption: a dark matter halo with a shallow core, an inner baryon-dominated region and a larger proportion of Dark Matter in smaller objects. However, the resulting size of the the dark halo core and of the inner baryon dominance region are somewhat smaller. The stronger role that VML discs have in the innermost regions is important to constrain the galaxy mass structure in both Lambda Cold Dark Matter and MOND scenarios.

description: We discuss the reflection of light by a rheoscopic fluid (a suspension of microscopic rod-like crystals) in a steady two-dimensional flow. This is determined by an order parameter which is a non-oriented vector, obtained by averaging solutions of a nonlinear equation containing the strain rate of the fluid flow. Exact solutions of this equation are obtained from solutions of a linear equation which are analogous to Bloch bands for a one-dimensional Schrodinger equation with a periodic potential. On some contours of the stream function, the order parameter approaches a limit, and on others it depends increasingly sensitively upon position. However, in the long-time limit a local average of the order parameter is a smooth function of position in both cases. We analyse the topology of the order parameter and the structure of the generic zeros of the order parameter field.

description: For fixed positive integers $n$, we study the solution of the equation $n = k + p_k$, where $p_k$ denotes the $k$th prime number, by means of the iterative method \[ k_{j+1} = π(n-k_j), \qquad k_0 = π(n), \] which converges to the solution of the equation, if it exists. We also analyze the equation $n = ak + bp_k$ for fixed integer values $a \ne 0$ and $b>0$, and its solution by means of a corresponding iterative method. The case $a>0$ is somewhat similar to the case $a=b=1$, while for $a<0$ the convergence and usefulness of the method are less satisfactory. The paper also includes a study of the dynamics of the iterative methods.

Creators: name: White, Richard L.
Publisher: name: Utah State University
Year: 1972

description: This paper is about organizational behavior and one man's research and ideas about this subject. That man is Chris Argyris.
Chris Argyris has been at Yale University for nearly two decades as a professor of Industrial Administration until recently moving to Harvard. During that period of time he has evolved from a beginning student of the behavioral sciences to a respected scholar and research authority in the field of organizational behavior. His own ideas have changed from a beginning theoretical framework to more established and accepted commentaries on organizational behavior.
The purpose of this paper is to dissect and explain Argyris's ideas and theories about the broad field of human relations in organizations called organizational behavior. The paper could also serve as an introduction to organizational behavior for the uninitiated.
This author will not attempt to criticize nor condone the work done by Argyris. Such a task will be left for the more informed student of organizational behavior. The paper will make an effort to describe Argyris's viewpoints on the different aspects of organizational behavior from his early beginnings to his more recent works. The reader will witness that Argyris retains many of his early premises throughout the span covered, As would be predicted Argyris also produced new ideas, theories, and techniques as he continued his research.

description: We show that all M-theory backgrounds which admit more than 29 Killing spinors are maximally supersymmetric. In particular, we find that the supercovariant curvature of all backgrounds which preserve 30 supersymmetries, subject to field equations and Bianchi identities, vanishes, and that there are no such solutions which arise as discrete quotients of maximally supersymmetric backgrounds.

Subjects: subject: Chaotic Dynamics (nlin.CD)

description: We study numerically chaotic behavior associated with a hyperbolic strange attractor of Plykin type in the model of Hunt, an artificially constructed dynamical system with continuous time. There are presented portraits of the attractor, plots of realizations for chaotic signal generated by the system, illustrations of the sensitive dependence on initial conditions for the trajectories on the attractor. Quantitative characteristics of the attractor are estimated, including the Lyapunov exponents and the attractor dimension. We discuss symbolic dynamics on the attractor, find out and analyze some unstable periodic orbit belonging to the attractor.

Horava-Lifshitz gravity, absolute time, and objective particles in curved space

description: Recently, Horava formulated a renormalizable theory of quantum gravity that reduces to general relativity at large distances but violates Lorentz invariance at small distances. The absolute time involved in this theory allows to define an objective notion of particles associated with quantization of fields in classical gravitational backgrounds. The Unruh effect and other observer-dependent notions of particles in curved space are interpreted as effects caused by interaction between the objective vacuum and the measuring apparatus made up of objective particles.

description: We construct examples of static, spherically symmetric wormhole solutions in general relativity with a minimally coupled scalar field $ϕ$ whose kinetic energy is negative in a restricted region of space near the throat (of arbitrary size) and positive far from it. Thus in such configurations a "ghost" is trapped in the strong-field region, which may in principle explain why no ghosts are observed under usual conditions. Some properties of general wormhole models with the $ϕ$ field are revealed: it is shown that (i) trapped-ghost wormholes are only possible with nonzero potentials $V(ϕ)$; (ii) in twice asymptotically flat wormholes, a nontrivial potential $V(ϕ)$ has an alternate sign, and (iii) a twice asymptotically flat wormhole which is mirror-symmetric with respect to its throat has necessarily a zero Schwarzschild mass at both asymptotics.

Generalized Jarzynski Equality under Nonequilibrium Feedback Control
Creators: name: Sagawa, Takahiro
name: Ueda, Masahito
Publisher: name: arXiv
Year: 2009
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: The Jarzynski equality is generalized to situations in which nonequilibrium systems are subject to a feedback control. The new terms that arise as a consequence of the feedback describe the mutual information content obtained by measurement and the efficacy of the feedback control. Our results lead to a generalized fluctuation-dissipation theorem that reflects the readout information, and can be experimentally tested using small thermodynamic systems. We illustrate our general results by an introducing "information ratchet," which can transport a Brownian particle in one direction and extract a positive work from the particle.

description: The Karhunen-Loève transform (KLT) is often used for data decorrelation and dimensionality reduction. Because its computation depends on the matrix of covariances of the input signal, the use of the KLT in real-time applications is severely constrained by the difficulty in developing fast algorithms to implement it. In this context, this paper proposes a new class of low-complexity transforms that are obtained through the application of the round function to the elements of the KLT matrix. The proposed transforms are evaluated considering figures of merit that measure the coding power and distance of the proposed approximations to the exact KLT and are also explored in image compression experiments. Fast algorithms are introduced for the proposed approximate transforms. It was shown that the proposed transforms perform well in image compression and require a low implementation cost.

description: Intelligent edge devices with built-in processors vary widely in terms of capability and physical form to perform advanced Computer Vision (CV) tasks such as image classification and object detection, for example. With constant advances in the field of autonomous cars and UAVs, embedded systems and mobile devices, there has been an ever-growing demand for extremely efficient Artificial Neural Networks (ANN) for real-time inference on these smart edge devices with constrained computational resources. With unreliable network connections in remote regions and an added complexity of data transmission, it is of an utmost importance to capture and process data locally instead of sending the data to cloud servers for remote processing. Edge devices on the other hand, offer limited processing power due to their inexpensive hardware, and limited cooling and computational resources. In this paper, we propose a novel deep convolutional neural network architecture called EffCNet which is an improved and an efficient version of CondenseNet Convolutional Neural Network (CNN) for edge devices utilizing self-querying data augmentation and depthwise separable convolutional strategies to improve real-time inference performance as well as reduce the final trained model size, trainable parameters, and Floating-Point Operations (FLOPs) of EffCNet CNN. Furthermore, extensive supervised image classification analyses are conducted on two benchmarking datasets: CIFAR-10 and CIFAR-100, to verify real-time inference performance of our proposed CNN. Finally, we deploy these trained weights on NXP BlueBox which is an intelligent edge development platform designed for self-driving vehicles and UAVs, and conclusions will be extrapolated accordingly.

title: The Thermolysis of Bornyl and Iso-Bornyl Acetates
Creators: name: Jensen, Allen Reed
Publisher: name: Utah State University
Year: 1974

description: Recent investigations in the area of acetate gas phase thermolysis indicate a mechanism which involves a similar transition state despite the acetate used. The reaction preferentially goes through a cis-elimination with the β-hydrogen atoms, proceeding through a six-membered ring transition state.
The purpose of this study is to examine the effect of a strained bicyclic ring system upon the mechanism of acetate thermolysis. Throuqh kinetic studies and product identification of the pyrolyzed products of bornyl and iso-bornyl acetate, an insight into the preferred mechanism can be obtained. A previous study (cited later) indicated that the accepted six-membered cis-elimination is not the mechanism which strained bicyclic acetates preferred. This paper will, therefore, examine this question and determine if inconsistent products and kinetics are indeed obtained.

Correlations between Ultrahigh Energy Cosmic Rays and Infrared-Luminous Galaxies

description: We confirm the UHECR horizon established by the Pierre Auger Observatory using the heterogeneous Veron-Cetty Veron (VCV) catalog of AGNs, by performing a redshift-angle-IR luminosity scan using PSCz galaxies having infrared luminosity greater than 10^{10}L_sun. The strongest correlation -- for z < 0.016, psi = 2.1 deg, and L_ir > 10^{10.5}L_sun -- arises in fewer than 0.3% of scans with isotropic source directions. When we apply a penalty for using the UHECR energy threshold that was tuned to maximize the correlation with VCV, the significance degrades to 1.1%. Since the PSCz catalog is complete and volume-limited for these parameters, this suggests that the UHECR horizon discovered by the Pierre Auger Observatory is not an artifact of the incompleteness and other idiosyncrasies of the VCV catalog. The strength of the correlation between UHECRs and the nearby highest-IR-luminosity PSCz galaxies is stronger than in about 90% percent of trials with scrambled luminosity assignments for the PSCz galaxies. If confirmed by future data, this result would indicate that the sources of UHECRs are more strongly associated with luminous IR galaxies than with ordinary, lower IR luminosity galaxies.
