Toward an Autopoietic Perspective on Information Systems Organization (2002)

This paper applies autopoietic theory to examine the nature of IS–organization relationships involving coevolutionary processes among an organization and its IS, IS organization issues, and the impacts on an organization’s competitive advantage. By drawing on a longitudinal field study in an international investment banking organization, where the development of a core IS has been studied since 1999, this paper (1) presents the distinct characteristics of the autopoietic approach; (2) demonstrates its explanatory power for understanding the IS–organization coevolutionary processes and IS organization, and (3) shows the implications of these autopoietic explanations for the firm’s current and future competitive advantage.

Material Exchange in Photoreceptor Transplantation: Updating Our Understanding of Donor/Host Communication and the Future of Cell Engraftment Science (2018)

Considerable research effort has been invested into the transplantation of mammalian photoreceptors into healthy and degenerating mouse eyes. Several platforms of rod and cone fluorescent reporting have been central to refining the isolation, purification and transplantation of photoreceptors. The tracking of engrafted cells, including identifying the position, morphology and degree of donor cell integration post-transplant is highly dependent on the use of fluorescent protein reporters. Improvements in imaging and analysis of transplant recipients have revealed that donor cell fluorescent reporters can transfer into host tissue though a process termed material exchange (ME). This recent discovery has chaperoned a new era of interpretation when reviewing the field's use of dissociated donor cell preparations, and has prompted scientists to re-examine how we use and interpret the information derived from fluorescence-based tracking tools. In this review, we describe the status of our understanding of ME in photoreceptor transplantation. In addition, we discuss the impact of this discovery on several aspects of historical rod and cone transplantation data, and provide insight into future standards and approaches to advance the field of cell engraftment.
Application of Ion Chromatography in Clinical Studies and Pharmaceutical Industry (2014)

Ion chromatography is a well-established regulatory method for analyzing anions and cations in environmental, food and many other samples. It offers an enormous range of possibilities for selecting stationary and mobile phases. Additionally, it usually helps to solve various separation problems, particularly when it is combined with different detection techniques. Ion chromatography can also be used to determine many ions and substances in clinical and pharmaceutical samples. It provides: availability of high capacity stationary phases and sensitive detectors; simple sample preparation; avoidance of hazardous chemicals; decreased sample volumes; flexible reaction options on a changing sample matrix to be analyzed; or the option to operate a fully-automated system. This paper provides a short review of the ion chromatography applications for determining different inorganic and organic substances in clinical and pharmaceutical samples.

Thermal Conductivity Equations Based on Brownian Motion in Suspensions of Nanoparticles (Nanofluids) (2008)

Thermal conductivity equations for the suspension of nanoparticles (nanofluids) have been derived from the kinetic theory of particles under relaxation time approximations. These equations, which take into account the microconvection caused by the particle Brownian motion, can be used to evaluate the contribution of particle Brownian motion to thermal transport in nanofluids. The relaxation time of the particle Brownian motion is found to be significantly affected by the long-time tail in Brownian motion, which indicates a surprising persistence of particle velocity. The long-time tail in Brownian motion could play a significant role in the enhanced thermal conductivity in nanofluids, as suggested by the comparison between the theoretical results and the experimental data for the Al2O3-in-water nanofluids.
Cutaneous Melanoma in Women I. Exposure to Sunlight, Ability to Tan, and Other Risk Factors Related to Ultraviolet Light (1995)

A population-based case-control study of cutaneous malignant melanoma (CMM) was conducted in 452 women with melanoma and 930 control subjects aged 25-59 years in five San Francisco Bay Area counties between 1981 and 1986. Women were interviewed in their homes with regard to history of sunlight exposure and sunburns during different periods in their lives, phenotypic and host characteristics, medical history, occupation, and demographic factors. Data were analyzed by the patients' histologic type of melanoma; 355 women were classified as having superficial spreading melanoma (SSM), 61 had nodular melanoma (NM), 13 had lentigo maligna melanoma, and 23 had other melanomas that could not be further classified upon histologic review by University of California dermatopathologists. Univariate results from analysis of factors related to sun exposure showed that the risk of all histologic types of CMM, SSM, and NM increased with increasing tendency of the subject to sunburn and with history of increased severity and/or frequency of sunburns up to age 12 years. Risk of all types of CMM and SSM also increased with increasing number of sunburns for all age groups and with lack of use of sunscreen. After adjustment for each other and for phenotypic factors, history of sunburn up to age 12 and lack of sunscreen use were the primary sun-related factors associated with an increased risk of all types of CMM and SSM, while tendency to sunburn when exposed to 1/2 hour of noontime sun and lack of use of sunscreen were related to NM. Although having frequent sunburns before age 12 and having severe sunburns before age 12 were both strongly associated with melanoma, having large numbers of sunburns during any time period from elementary school through age 30 years and having sunburns during the 10 years prior to diagnosis or interview were all associated with a doubling of risk for SSM after adjustment for other factors. These results suggest that the increased risk of melanoma related to sunburns is not confined to childhood sunburns. Maintenance of an all-year tan provided no protective effect against melanoma after adjustment for tendency to burn. No association was noted with use of fluorescent lights or exposure to sunlamps for all types of CMM, SSM, or NM.
Adaptive threshold control scheme for packet acquisition (1998)

An adaptive threshold control scheme for packet acquisition is described. The threshold control is done adaptively by setting the threshold proportional to the maximum likelihood estimate of the noise power.
Thirty Years of DNS Insecurity: Current Issues and Perspectives (2021)

When DNS was created, nobody expected that it would have become the base for the digital economy and a prime target for cybercriminals. And nobody expected that one main asset of the digital economy would have been users’ browsing habits, putting at risk their privacy. The DNS was designed and implemented according to speed, scalability, and reliability criteria, whereas security and privacy did not fit in the objectives. Although the first attacks were already conceived about thirty years ago, the DNS infrastructure - with a bunch of improvements but its original design - continues to play a pivotal role in enabling access to services, data and devices. And, despite the fairly widespread adoption of DNSSEC security extensions in recent years, DNS attacks are becoming more and more frequent, sophisticated and dangerous. They are global, varied, dynamic and can circumvent traditional security systems such as next-generation firewalls and data loss prevention systems. A revisitation of DNS assumptions has been proposed in very different ways, reflecting diverse point of views in terms of Internet governance and user freedom, and a great effort is in place by standardization bodies, industry consortia and academic research to converge toward an updated design and implementation. The present work overviews the most promising proposals, trying to shed some insight on the future of DNS.

TCR modifications that enhance chain pairing in gene-modified T cells can augment cross-reactivity and alleviate CD8 dependence (2018)

T cell receptor (TCR) gene-modified T cells are a promising immunotherapy but require refinement to improve clinical responses and limit off-target toxicities. A variety of TCR and gene-delivery vector modifications have been developed to enhance introduced TCR expression and limit introduced/endogenous TCR chain mispairing, improving target antigen recognition and minimizing mispairing-induced cross-reactivity. Using our well-characterized HCV1406 TCR, we previously compared the impact of various chain pairing enhancing modifications on TCR expression and cognate antigen recognition. HCV1406 TCR is also natively cross-reactive against naturally occurring altered peptide ligands (APLs), which was shown to be dependent on high TCR surface density. In this report, we observed in a Jurkat model that absent TCR chain pairing competition alleviated CD8-dependent APL recognition and induced novel cross-reactivity of HCV1406 TCR. We then compared chain pairing enhancing modifications' effects on TCR cross-reactivity in Jurkat and T cells, showing C-terminal leucine zippers and constant region murinization alleviated CD8 dependence and induced novel APL recognition. While modifications enhancing TCR chain pairing intend to avoid cross-reactivity by limiting mispairing with the endogenous TCR, these data suggest they may also enhance natural cross-reactivity and reduce dependence on CD8. These observations have significant implications on the design/implementation of TCR gene-modified T cells.
Off-Site Regeneration of Hydroprocessing Catalysts (1995)

This paper describes the basic phenomena occurring during oxidative regeneration of hydroprocessing catalysts, as well as laboratory experiments studying the removal of carbon and sulfur as a function of temperature. In addition, the evolution of Surface Area (SA) and Dynamic Oxygen Chemisorption (DOC) values versus regeneration temperature applied is discussed. DOC is used to evaluate the dispersion of the active metal-sulfide phase. DOC and SA measurements are complementary techniques for quality assurance of the regeneration process. A substantial loss of SA is found above 600°C while DOC values begin to decrease at lower temperatures. As regards combustion of C and S, it was found that carbon is readily eliminated in a single step between 300 and 450°C. The elimination of sulfur starts as low as 150°C and is terminated only at high temperatures (>600°C). The combustion of C and S, however, seems to be limited by an oxygen diffusion effect into the pores of the catalyst. The EURECAT regeneration process is described as well as an example of an industrial regeneration. Finally, the regulation aspects concerning handling and transport of spent hydroprocessing catalyst are discussed. The safety aspects for unregenerated catalysts are covered by ADR and IMDG codes, but new European legislation exists concerning waste transport including spent catalyst transport. This may result in stricter regulations concerning the transport of spent catalyst from refinery to regeneration facilities in the very near future.

Origin of the vertebrate inner ear: evolution and induction of the otic placode (2001)

The vertebrate inner ear forms a highly complex sensory structure responsible for the detection of sound and balance. Some new aspects on the evolutionary and developmental origin of the inner ear are summarised here. Recent molecular data have challenged the longstanding view that special sense organs such as the inner ear have evolved with the appearance of vertebrates. In addition, it has remained unclear whether the ear originally arose through a modification of the amphibian mechanosensory lateral line system or whether both evolved independently. A comparison of the developmental mechanisms giving rise to both sensory systems in different species should help to clarify some of these controversies. During embryonic development, the inner ear arises from a simple epithelium adjacent to the hindbrain, the otic placode, that is specified through inductive interactions with surrounding tissues. This review summarises the embryological evidence showing that the induction of the otic placode is a multistep process which requires sequential interaction of different tissues with the future otic ectoderm and the recent progress that has been made to identify some of the molecular players involved. Finally, the hypothesis is discussed that induction of all sensory placodes initially shares a common molecular pathway, which may have been responsible to generate an 'ancestral placode' during evolution.
Polar Codes for the $m$-User Multiple Access Channel (2012)

In this paper, polar codes for the m-user multiple access channel (MAC) with binary inputs are constructed. It is shown that Arikan's polarization technique applied individually to each user transforms independent uses of an m-user binary input MAC into successive uses of extremal MACs. This transformation has a number of desirable properties: 1) the “uniform sum-rate” of the original MAC is preserved, 2) the extremal MACs have uniform rate regions that are not only polymatroids but matroids, and thus, 3) their uniform sum-rate can be reached by each user transmitting either uncoded or fixed bits; in this sense, they are easy to communicate over. A polar code can then be constructed with an encoding and decoding complexity of O(n log n) (where n is the block length), a block error probability of o(exp (- n <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1/2 - ε</sup> )), and capable of achieving the uniform sum-rate of any binary input MAC with arbitrary many users. Applications of this polar code construction to channels with a finite field input alphabet and to the additive white Gaussian noise channel are also discussed.

Ultrastructure Studies of Pasta. A Review. (1983)

Freeze-fracturing can be used effectively to study pasta microstructure both in the dry and cooked state. Aft er a walerglycerol soaking. conventional raw wheat pasta shows an uncoagulated protein matrix in which the starch granules are uniformly dispersed. Starch granules appear unswollen with a spherulitic structure. Extensive protein denaturation and starch swelling may occur during processing when a temperature greater than 60°C is attained in drying. Extensive structural transformations take place in cooking. A fibrillar protein network which envelops gelatinized starch is the typical structure observed in cooked durum wheat spaghetti. Whereas. in soft wheat products, there is a less extensive protein framework with more diffuse starch particles. Pasta cooking quality is determined by a physical competition between protein coagulation into a continuous network (I) and starch swelling with spherulite scattering (II) during cooking. If the former (I) prevails, starch particles are trapped in the network alveoli promoting firmness in cooked pasta : Whereas if the latter ( II) prevails, the protein coagulates in discrete masses lacking a continuous framework and pasta will show softness and usually stickiness. High temperature-low moisture (HT-LM) drying partially overcomes this competition by producing a coagulated protein framework in dry pasta without starch swelling. HT-LM treatment induces protein-starch interactions and conformational changes in the starch granule fine structure during cooking. Linear and branched chain-like fibrils appear in the core of the granules and particle groupings in the outer area. The better understanding of the role of controlled starch modification which optimizes pasta processing permits better use of non-conventional raw materials in pasta preparation.

Scalable relevance feedback using click-through data for web image retrieval (2006)

Relevance feedback (RF) has been extensively studied in the content-based image retrieval community. However, no commercial Web image search engines support RF because of scalability, efficiency and effectiveness issues. In this paper we proposed a scalable relevance feedback mechanism using click-through data for web image retrieval. The proposed mechanism regards users' click-through data as implicit feedback which could be collected at lower cost, in larger quantities and without extra burden on the user. During RF process, both textual feature and visual feature are used in a sequential way. To seamlessly combine textual feature-based RF and visual feature-based RF, a query concept-dependent fusion strategy is automatically learned. Experimental results on a database consisting of nearly three million Web images show that the proposed mechanism is wieldy, scalable and effective.
Olfactory tau pathology in Alzheimer disease and mild cognitive impairment. (2007)

These data confirm previous studies demonstrating considerable tau pathology in the olfactory system in all definite AD cases, in more than 2/3 of limbic AD and in more than 1/3 of elderly individuals with or without mild cognitive impairment associated with Braak stage 2. Clinical dementia correlated with both Braak and olfactory tau scores, indicating that both are associated with a high risk of cognitive decline.
THE EFFECT OF COLLOID CONCENTRATION ON THE FUNCTIONAL CHARACTERISTICS OF ISOLATED PERFUSED RAT LIVER (1977)

The volume of bile produced by isolated perfused rat liver was dependent on the concentration of bovine serum albumin (BSA) in the perfusate, the lowest volumes being obtained with Krebs Ringer bicarbonate (KRB alone and with 70 g/l. BSA in KRB. Increasing amounts were produced as the concentration of BSA was reduced from 70 g/l. to 8.5 g/l. The concentration of bile salts in the bile decreased rapidly during the first hour, but much more slowly thereafter. The highest concentration observed during the first hour was with KRB alone and the lowest with 20 g/l. BSA; subsequently, the highest concentrations were obtained with 70 g/l. BSA and the lowest with 20 g/l. BSA. Urea synthesis was lowest with KRB alone, but increased as the concentration of BSA increased; however, values obtained with 8.5, 20, and 40 g/l. were fairly close together. With KRB alone there was a rapid release of potassium during the first hour, but thereafter the rate of release was similar to that found when BSA was present. The lowest concentrations of potassium were obtained with 20 and 40 g/l. BSA. With KRB alone, GOT was released from the start of perfusion of 300 units per minute. With BSA present, GOT release was delayed 4 hours, and thereafter the rate was dependent on the concentration of BSA, being lowest with 20 and 40 g/l. (200 units per min), higher with 8.5 g/l. (350 units per min) and highest with 70 g/l. (400 units per min).
