Notice to GODORT Membership: Vote to Amend the GODORT Bylaws (2017)

At the GODORT General Membership meeting at the 2017 ALA Conference, the membership will be asked to vote on the following proposed additions (and amendments) to the current GODORT Bylaws. These would provide for a “Bylaws and Organization Coordinator.” This new officer would supplant the current Bylaws and Organization standing Committee and perform the current functions of the Committee, as defined in the GODORT Bylaws [Article XI. Amendments] and in Chapter 13 of the GODORT Policies and Procedures Manual. The underlined text will be added to Article IV (Officers), Section 1 and Section 8 [The current Section 8, which defines the GODORT Special Officers, will be re-numbered Section 9] and to Article VII (Executive Committee). Article IX (Policies and Procedures) and Article XI (Amendments), Sections 2 and 3 will need to be harmonized, to reflect substitution in the Bylaws of “Bylaws and Organization Coordinator” for references to the Bylaws Committee and Chair of the Bylaws Committee:
Mammalian endonuclease, DNase V. Purification and properties of enzyme of calf thymus. (1977)

An endonuclease present in partially purified preparations of calf thymus DNA polymerase has been purified to homogeneity. It has a molecular weight of 53,000 +/- 2,500 as determined by sucrose gradient sedimentation. Polyacrylamide gel electrophoresis in the presence of sodium dodecyl sulfate indicates the protein is composed of four subunits, each polypeptide possessing a molecular weight of 13,000. Its isoelectric point is 10.3 +/- 0.2. The endonuclease has a pH optimum at 6.6, requires Mg2+ or Mn2+ for activity, and does not attack RNA. The enzyme appears to be present in tissues other than calf thymus. The enzyme catalyzes the endonucleolytic cleavage of both denatured and native eukaryotic DNA. The enzyme introduces a limited number of single strand nicks into native DNA; hydrolysis of denatured DNA produces acid-soluble oligonucleotides. The average size of the limit product, sedimented in an alkaline sucrose gradient, is 1200 nucleotides for native DNA. The product contains 5'-phosphoryl and 3'-hydroxyl termini. While all four deoxynucleotides are found at the 5' termini, pyrimidine residues predominate. Calf thymus DNase V degrades closed circular duplex SV40 DNA and glucosylated T4DNA but not poly(dA-dT). The rate of hydrolysis of homopolymers is: poly(dT) greater than poly(dA) greater than poly(dC) greater than poly(dG) in the presence of Mg2+, and poly(dT) greater than poly(dC) greater than poly(dA) = poly(dG) in the presence of Mn2+.
The Peruvian Revolution and its Aftermath (1994)

To what extent, it must be asked, could the endemic problems of Peru — its chronic poverty, backwardness and underdevelopment, its gross social inequality and exploitation, its dependence on foreign capital — be solved by a far-reaching national revolution? And since these conditions both characterise and underpin the situation of the peasantry, would their amelioration assist the peasants to escape from the poverty trap and evolve to a status approaching that of small farmers, who might expect to enjoy a lifestyle of simple but modest decency and self-respect?
Digital rights technology sparks interoperability concerns (2004)

Digital media is a killer application for the Internet. However, concerns about the technology have limited the commercial distribution of digital video, audio, and images. Most notably, content producers worry that purchasers will copy and give away or resell their products in ways that the providers don't want and that violate their licenses. In light of this, companies have developed digital rights management (DRM) technology for products and media players to let content producers enforce licensing restrictions by limiting the use of their materials. However, this has led to a critical problem for the digital-media industry: most DRM technologies are not interoperable. Most vendors have created proprietary technologies not available for license or use by third-party vendors, thereby making interoperability difficult. With digital content becoming a big business, the industry is concerned about interoperability. A series of initiatives are under way to address DRM interoperability.

Multimode Flex-Interleaver Core for Baseband Processor Platform (2010)

This paper presents a flexible interleaver architecture supporting multiple standards like WLAN, WiMAX, HSPA+, 3GPP-LTE, and DVB. Algorithmic level optimizations like 2D transformation and realization of recursive computation are applied, which appear to be the key to reach to an efficient hardware multiplexing among different interleaver implementations. The presented hardware enables the mapping of vital types of interleavers including multiple block interleavers and convolutional interleaver onto a single architecture. By exploiting the hardware reuse methodology the silicon cost is reduced, and it consumes 0.126 <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:mrow><mml:msup><mml:mrow><mml:mtext>mm</mml:mtext></mml:mrow><mml:mn>2</mml:mn></mml:msup></mml:mrow></mml:math>area in total in 65 nm CMOS process for a fully reconfigurable architecture. It can operate at a frequency of 166 MHz, providing a maximum throughput up to 664 Mbps for a multistream system and 166 Mbps for single stream communication systems, respectively. One of the vital requirements for multimode operation is the fast switching between different standards, which is supported by this hardware with minimal cycle cost overheads. Maximum flexibility and fast switchability among multiple standards during run time makes the proposed architecture a right choice for the radio baseband processing platform.

On the stability of viscous flow between parallel planes in the presence of a co-planar magnetic field (1954)

Abstract Linearized equations are derived which govern the stability of a viscous, electrically conducting fluid in motion between two parallel planes in the presence of a co-planar magnetic field. With one suitable approximation, which restricts the valid range of Reynolds number of the theory, the problem of stability is reduced to the solution of a fourth-order ordinary differential equation. The disturbances considered are neither amplified nor damped, but are neutral. Curves of wave number against Reynolds number for neutral stability are calculated for a range of values of a certain parameter, q, which represents the magnetic effects. For given physical and geometrical properties, the critical Reynolds number above which the flow is unstable rises with the strength of the magnetic field. These results are completely within the range of the approximation mentioned. In addition, an energy relation is derived which illustrates the balance between energy transferred from the basic flow to the disturbances, and that dissipated by viscosity and by the magnetic field perturbations.

Absence of HLA linkage in a family with osteitis deformans (Paget's disease of bone) (1988)

HLA genotyping was carried out on a two-generation family with familial osteitis deformans. No evidence of major histocompatibility linkage of the disease could be demonstrated.
Comparative Studies of Morphological Changes and Interleukin Concentration in Subretinal Fluid of Patients with Retinal Detachment (1998)

Morphological evaluation was performed with the light and scanning electron microscope of subretinal fluids (SRF) collected during operations from 36 patients with rhegmatogenous retinal detachment. Duration of the disease was 3 weeks, 5-8 weeks, 10 weeks and 6 months. The immunoenzymatic method was used to establish the presence of interleukins IL-1beta, IL-2, IL-4 and IL-6 in SRF. It was revealed that the differentiation of the morphological picture of SRF depended on the duration of detachment. Most cell-rich SRF came from the 3-week detachment. Mononuclear cells were predominant in that period (macrophages, lymphocytes). In the later period (over 8 weeks) a decrease in the number of cells and a change in cellular composition were noted in the fluids examined, while after six months of detachment normal cellular elements were absent. In all time intervals analyzed, no significant increase in IL-1beta, IL-2 and IL-4 was noted in SRF. However, a significant quantity of IL-6 was found, particularly in the 5- to 8-week detachment. The authors assume that the presence of a large number of inflow cells in 'fresh' detachment can trigger a variety of inflammation-based immunological processes which stimulate the development of vitreoretinal proliferation.
Resistive Switching Characteristics of Solution-Processed Transparent TiO[sub x] for Nonvolatile Memory Application (2010)

We propose a solution-processed transparent -based resistive switching random access memory (ReRAM) device. Electronically active was prepared by sol–gel spin coating of a titanium(IV) isopropoxide precursor on an indium tin oxide-coated glass. The prepared film is completely transparent in the visible range and has an amorphous structure. The fabricated -based ReRAM device exhibits distinct resistive switching under consecutive dc voltage sweeps of . The device also exhibits good memory performance, including fast switching speed with a pulse width of , stable pulse endurance over 1000 cycles, and excellent retention characteristics at up to . In addition, based on the plot and X-ray photoelectron spectroscopy analysis, we postulate that the fabricated device is operated by the reversible formation/rupture of the conducting filament in the oxygen-deficient layer.
Quasi-convexity and lower semi-continuity of multiple variational integrals of any order (1965)

Introduction.The purpose of this paper is the determination of necessary and sufficient conditions for the lower semi-continuity, under various kinds of convergence, of integrals of the form I(u;)= f /(x,(x),-,D'u(x))dx. JaHere x = (x1, -, x"),u = (u1, -,u"'), 2 is a bounded domain and the integrand fix,p,---,p') is a continuous function of its arguments.In 1952 Morrey studied the case I = 1 and introduced the concept of quasiconvexity (see [3]).Extending this concept to the cases I = 1, we say that an integrand /(p') is quasi-convex if each polynomial of degree g / minimizes the integral, J"n/(D'n(x))dx, among all functions whose derivatives of order I-I satisfy a Lipschitz condition on 2 (we denote this function space by ^''""(Q)) and assume the same Dirichlet data on dQ as the polynomial.The reason for the term quasi-convexity becomes clear when one sees that convexity implies quasiconvexity and quasi-convexity in turn implies the Legendre condition (at least for smooth integrands) which contains within it various convexities.Hence, quasi-convexity is a condition which falls between convexity and a weaker kind of convexity.In Theorems 1 and 2 of 2,1 extend Morrey's results by showing that the necessary and sufficient condition for lower semi-continuity of 7(w;Q) in "^''"(fi), under uniform convergence of derivatives of order z% I -1 and uniform boundedness of derivatives of order /,is that/(x,p0,-..,p') be quasi-convex in p'for each fixed value of the variables (x,p, -,p'-1).The proof is a straightforward extension of Morrey's for the case 1=1.However, it contains the added feature that the necessity is derived asssuming only that the admissible functions satisfy fixed Dirichlet boundary conditions.I then go on to consider lower semi-continuity under weak convergence in a space Wl,'(Cl) (1 -g r < oo ), the space of functions with strong derivatives up to the order / which are in fr(Q).Two cases are considered, though they do not require separate treatment: first, the case where the admissible functions satisfy a fixed Dirichlet boundary condition, and second, the case of no boundary condition.
What's your strategy for managing knowledge? (1999)

The rise of the computer and the increasing importance of intellectual assets have compelled executives to examine the knowledge underlying their businesses and how it is used. Because knowledge management as a conscious practice is so young, however, executives have lacked models to use as guides. To help fill that gap, the authors recently studied knowledge management practices at management consulting firms, health care providers, and computer manufacturers. They found two very different knowledge management strategies in place. In companies that sell relatively standardized products that fill common needs, knowledge is carefully codified and stored in databases, where it can be accessed and used--over and over again--by anyone in the organization. The authors call this the codification strategy. In companies that provide highly customized solutions to unique problems, knowledge is shared mainly through person-to-person contacts; the chief purpose of computers is to help people communicate. They call this the personalization strategy. A company's choice of knowledge management strategy is not arbitrary--it must be driven by the company's competitive strategy. Emphasizing the wrong approach or trying to pursue both can quickly undermine a business. The authors warn that knowledge management should not be isolated in a functional department like HR or IT. They emphasize that the benefits are greatest--to both the company and its customers--when a CEO and other general managers actively choose one of the approaches as a primary strategy.
Assessing the influence of culture on oralhealth-a review (2014)

Man is a social animal, influenced by physical, biological and social environment. This social world of an individual is further influenced by culture. Cultural factors in health and disease have engaged the attention of medical scientists and Sociologists. These include concept of etiology and cure based cultural beliefs, habits, adverse oral habits like eating arecanut and pan chewing, parental influence, marriage-practices, rural –urban influence, social class, urban/rural society, socioeconomic status, race/ethnicity, geographic location, religion, familial influence, gender and cultural taboos. All these factors influence oral health as well and may have an effect on the occurrence, outcome and prognosis of many oral diseases. This review article assesses the influence of culture on oral health which will help us to understand the etiology as well as decide upon the treatment options for various oral diseases.
Integration of virtual reality based assembly simulation into CAD/CAM environments (2002)

Due to growing, worldwide competition, manufacturing companies have to employ new technologies to cut costs, improve product quality and, more importantly, shorten the design-to-manufacturing and -assembly cycle for new products. During recent years, virtual reality (VR) has proved its potential for the visualization and interactive manipulation of complex data. This paper describes a process for integrating an interactive VR-based assembly simulation of a digital mockup into an existing CAD/CAM infrastructure. The necessary hard- and software preconditions for the process are explained so that it can easily be adopted by nonVR-specialists. The article outlines how assembly simulation can improve the CAD/CAM procedures and structures, which CAD model preparations have to be carried out and which virtual environment requirements have to be fulfilled. Finally, deficits of existing VR simulation software are discussed and possible solutions and necessary developments are presented.
Ca <sup>2+</sup> -Dependent Rapid Ca <sup>2+</sup> Sensitization of Contraction in Arterial Smooth Muscle (2006)

Ca(2+) ion is a universal intracellular messenger that regulates numerous biological functions. In smooth muscle, Ca(2+) with calmodulin activates myosin light chain (MLC) kinase to initiate a rapid MLC phosphorylation and contraction. To test the hypothesis that regulation of MLC phosphatase is involved in the rapid development of MLC phosphorylation and contraction during Ca(2+) transient, we compared Ca(2+) signal, MLC phosphorylation, and 2 modes of inhibition of MLC phosphatase, phosphorylation of CPI-17 Thr38 and MYPT1 Thr853, during alpha(1) agonist-induced contraction with/without various inhibitors in intact rabbit femoral artery. Phenylephrine rapidly induced CPI-17 phosphorylation from a negligible amount to a peak value of 0.38+/-0.04 mol of Pi/mol within 7 seconds following stimulation, similar to the rapid time course of Ca(2+) rise and MLC phosphorylation. This rapid CPI-17 phosphorylation was dramatically inhibited by either blocking Ca(2+) release from the sarcoplasmic reticulum or by pretreatment with protein kinase C inhibitors, suggesting an involvement of Ca(2+)-dependent protein kinase C. This was followed by a slow Ca(2+)-independent and Rho-kinase/protein kinase C-dependent phosphorylation of CPI-17. In contrast, MYPT1 phosphorylation had only a slow component that increased from 0.29+/-0.09 at rest to the peak of 0.68+/-0.14 mol of Pi/mol at 1 minute, similar to the time course of contraction. Thus, there are 2 components of the Ca(2+) sensitization through inhibition of MLC phosphatase. Our results support the hypothesis that the initial rapid Ca(2+) rise induces a rapid inhibition of MLC phosphatase coincident with the Ca(2+)-induced MLC kinase activation to synergistically initiate a rapid MLC phosphorylation and contraction in arteries with abundant CPI-17 content.
SAW Parameters Analysis and Equivalent Circuit of SAW Device (2011)

Surface Acoustic Wave (SAW) devices, using interdigital electrodes, play a key role in today’s telecommunication systems and are widely used as electronic filters, resonators, delay lines, convolvers or wireless identification systems (ID tags). During the last three decades, demands set by the expansion of the telecommunication industry and many applications in sensor have resulted in the introduction of a new generation of the SAW devices. Consequently, the design of high performance SAW devices requires precise and efficient models, simulation tools. Several methods have been proposed for modeling, analyzing SAW devices. These include the impulse model, the equivalent circuit models, the coupling-of-mode (COM) model, P-matrix model, angular spectrum of waves models [1] and the Scattering Matrix approach that was presented by Coldren and Rosenberg [2]. While the impulse model is only a first order model, the other models include second order effects, e.g. reflections, dispersion, and charge distribution effects. Purely numerical methods have also been and are being developed by many authors [3][35], [41]. In this chapter, the method for calculating the SAW parameters, including modeling and simulation, is given. Section 2 gives the calculation of SAW properties and analyses of different SAW device structures. Section 3 presents the equivalent circuit of SAW delay line based on Mason model. The equivalent circuit of SAW delay line based on Couple-Of-Mode theory is presented in section 4. Based on section 3 and 4, section 5 shows comparison between using the equivalent circuit of SAW delay line device based on Mason model and COM theory. This model is useful and fast model for designing the SAW device.
[ECG-triggered magnetic resonance tomographic measurement of blood flow velocity in the carotid arteries: comparison with duplex sonography]. (1988)

Blood flow velocity in the common carotid arteries was measured for 30 vessels by MRI with a multiecho SE-sequence and compared with the results from duplex ultrasound. MR blood flow velocity was measured for a time interval of 390 ms every 30 ms using a EKG-triggered data acquisition. The time-velocity curves measured by MRI and duplex ultrasound were in good agreement. The correlation coefficient for the peak velocity was r = 0.83. Mean peak velocity as measured by MRI was 59 +/- 8% of peak velocity as measured by duplex ultrasound.
Blockchain State Machine Representation (2018)

We present a formalization of blockchain as a state machine, focusing upon permissionless blockchains due to general audience awareness of its most popular implementation, Bitcoin (permissioned blockchains are treated similarly without loss of generality). After presenting a typical Bitcoin transaction workflow, a general blockchain state representation is derived. It is demonstrated that the proper mathematical object defining the state of a blockchain is a topological fiber bundle, because it is not possible to globally `parametrize' blocks (or ledgers of blocks) by time due to their dependence upon cryptographic hash functions. In addition, we specify a general transition function between blockchain states that is agnostic to the consensus mechanism used to write blocks into the ledger, and which is probabilistic in nature, so that blockchain may be regarded as a probabilistic state machine. We then interpret agents (both human and code-based, such as `chaincode', `smart contracts', or other artificial intelligence) as automata interacting with blockchain technology, drawing upon the theory of non-cooperative repeated interaction games. Finally, blockchain as a hierarchy of state machines is defined, and future research directions are presented using this hierarchy as a point of departure for modeling blockchain dynamics.
Interaction of beef liver lipase with mixed micelles of tripalmitin and Triton X-100 (1971)

When concentrated dispersions of tripalmitin in Triton X-100 are added to reaction mixtures containing soluble beef liver lipase, the rate of hydrolysis of tripalmitin increases with incubation time. When the diluted substrate is aged at 37 degrees C for 3 hr before the addition of enzyme, the rate of hydrolysis is greater than the rate with freshly diluted dispersions and is constant for at least 2 hr. The reciprocal of the rate of hydrolysis is a complex function of the reciprocal of the substrate concentration when measured with freshly diluted substrate dispersions. A linear relationship between these reciprocals is obtained when measured with aged preparations of substrate. The rate and extent of increase of the velocity of hydrolysis of the aged substrate in relation to the velocity of hydrolysis of freshly diluted substrate are directly proportional to the substrate concentration and inversely proportional to the Triton X-100 concentration. The apparent V(max) of beef liver lipase for tripalmitin in diluted and aged dispersions is independent of the Triton X-100 concentration, while the apparent K(m) is inversely proportional to the Triton X-100 concentration. The apparent K(m) for tripalmitin complexes at zero Triton X-100 concentration was judged to be 7.5 x 10(-5) m. The molecular size of dispersion complexes does not change significantly as dispersions are aged. The spherical diameter of the complexes assessed by gel filtration techniques is in the order of 100 A.
Growth and x-ray characterization of strain compensated GaAs/AlAs distributed Bragg reflectors (1996)

We have grown strain compensated GaAs/AlAs distributed Bragg reflectors by solid source molecular beam epitaxy using carbon doping densities up to about 2×1020 cm−3. The residual strain with respect to the GaAs substrate can be as low as 1×10−4. This results in a large increase of their critical thickness with regard to the undoped case. We demonstrate that simulations of the x-ray diffraction patterns are essential in order to determine the chemical profile as well as the structural parameters of the GaAs:C and AlAs:C layers with high accuracy. The effective incorporation of carbon on lattice sites is in AlAs:C twice as large as in GaAs:C using the same incident carbon flux.
