Towards a task-based paradigm for flexible and adaptable access control in distributed applications (1993)

Historically, the access control problem has been couched within the framework of subjects, object, and rights. In this paper we argue for a newer paradigm for distributed and multi-system applications, that transcends the subject-object view of access control. This new paradigm views access control and authorization not in terms of individual subjects and object, but rather in terms of long-lived tasks that need to be authorized and managed in information systems.
Candidate genes mediated by estrogen‐related receptor γ in pancreatic β cells (2019)

Recent studies have established the importance of estrogen-related receptor γ (ERRγ) as a required participant for insulin secretion in pancreatic β cells. Key downstream genes of ERRγ remain unclear in the pancreatic β cell. To understand the molecular role of ERRγ and elucidate potential key candidate genes involved in pancreatic β cells, the eukaryotic expression plasmid containing mouse ERRγ was constructed and transfected into NIT-1 pancreatic β cells. Overexpression of ERRγ was confirmed by quantitative real-time reverse-transcription polymerase chain reaction and Western blot analyses. RNA-seq was conducted to get the gene expression profiling between the overexpression group cells and control cells. Differentially expressed genes (DEGs) were identified by edgR and subsequently analyzed by gene ontology (GO) enrichment analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis. We found that overexpression of ERRγ in pancreatic β cells enables regulation of the expression of certain genes involved in cell apoptosis and mitochondrial function, such as TFPT, Bcl7c, Dap, Thoc6, Ube2d3, ATP5H, MPV17, and NDUFA6. GO analysis revealed that the DEGs were mainly enriched in apoptotic process, cytoplasm, and protein binding. KEGG pathway analysis demonstrated that downregulated DEGs were mainly enriched in protein processing in endoplasmic reticulum, estrogen signaling pathway, and metabolic pathways. This study helps to further understand and reposition the molecular mechanisms of ERRγ in β cells.

The Effects Of Query Complexity, Expansion And Structure On Retrieval Performance In Probabilistic Text Retrieval (1999)

The effects of query complexity, expansion and structure on retrieval performance - measured as precision and recall - in probabilistic text retrieval were tested. Complexity refers to the number of search facets or intersecting concepts in a query. Facets were divided into major and minor facets on the basis of their importance with respect to a corresponding request. Two complexity levels were tested: high complexity refers to queries using all search facets identified from requests, low complexity was achieved by formulating queries with major facets only. Query expansion was based on a thesaurus, from which the expansion keys were elicited for queries. There were five expansion types: (1) the first query version was an unexpanded, original query with one search key for each search concept (original search concepts) elicited from the test thesaurus; (2) the synonyms of the original search keys were added to the original query; (3) search keys representing the narrower concepts of the original search concepts were added to the original query; (4) search keys representing the associative concepts of the original search concepts were added to the original query; (5) all previous expansion keys were cumulatively added to the original query. Query structure refers to the syntactic structure of a query expression, marked with query operators and parentheses. The structure of queries was either weak (queries with no differentiated relations between search keys, except weights) or strong (different relationships between search keys). More precisely, strong query structures were based on facets or intersecting concepts. Altogether five weak and eight strong structure types were tested. The test involved 30 test requests which all were formulated into 110 queries representing different structure, expansion and complexity combinations. The test database was a text database of 53,893 newspaper articles. The test was run in InQuery, a probabilistic text retrieval system. The test revealed that when the queries were unexpanded, there were no great differences between different structure types irrespective of the complexity level. When queries were expanded, the performance of the weakly structured queries dropped, but the performance of the best strongly structured queries improved. The differences in performance between complexity levels varied by different expansions, but in all, differences were minor in this respect. The best performance was achieved with a combination of a facet structure, high complexity, and the largest expansion. However, all strong structures did not perform well with expansion. The operator combining search keys within a facet was more decisive than the operator combining facets. The typical interpretation given to the OR operator in partial match retrieval proved to be too permissive, and thus, performance decreased when queries were expanded. The best result was achieved by treating all search keys within a facet as instances of one search key, i.e., using the SYN operator as a 'facet operator'.
An Integrated Virtual Store-Based Approach for Price Determination Before Product Launch (2007)

An integrated model approach is developed to determine market prices for product options that a company can offer consumers before launching a product. The multiple research streams drawn on include pricing, new product launch, on-line experimentation, conjoint analysis, and optimization. The approach incorporates a consumer-response model that considers the cross-price effects of the options as well as the impact of competing product options and prices. Based on the response model, a profit-optimization model framework is applied in an actual market situation involving an on-line video game to be introduced in a foreign market. A description of the stages of the application, from empirical design and data collection to decision-making and postlaunch model validation, demonstrates the usefulness of the approach.
Minimization of sink mark defects in injection molding process – Taguchi approach (2010)

Optimal setting up of injection molding process variables plays a very important role in controlling the quality of the injection molded products. It is all the most important to control attribute defects like sink marks. Sink marks are basically a “designed in” problem and hence it is to be attended during designs stages. Owing to certain conditions and constraints, sometimes, it is rather ignored during design stages and it is expected to be handled by molders with only instruction to ‘do the best’. Handling of numerous processing variables to control defects is a mammoth task that costs time, effort and money. This paper presents a simple and efficient way to study the influence of injection molding variables on sink marks using Taguchi approach. Using the Taguchi approach, optimal parameter settings and the respective sink depth were arrived. The sink depth based on the validation trials was compared with the predicted sink depth and they are found to be in good agreement. The results demonstrate the ability of this approach to predict sink depth for various combination of processing variables with in the design space. Keywords: Sink mark, plastic injection molding, Taguchi optimization, process optimization, attribute defects in injection molding
A method of depth image based human action recognition (2017)

In this paper, we propose an action recognition algorithm framework based on human skeleton joint information. In order to extract the feature of human motion, we use the information of body posture, speed and acceleration of movement to construct spatial motion feature that can describe and reflect the joint. On the other hand, we use the classical temporal pyramid matching algorithm to construct temporal feature and describe the motion sequence variation from different time scales. Then, we use bag of words to represent these actions, which is to present every action in the histogram by clustering these extracted feature. Finally, we employ Hidden Markov Model to train and test the extracted motion features. In the experimental part, the correctness and effectiveness of the proposed model are comprehensively verified on two well-known datasets.

Inherited Channelopathies Associated with Epilepsy (2004)

Ion channels are critical for neuronal excitability and provide important targets for anticonvulsant drugs. In the past few years, several monogenetic epilepsies have been linked to mutations in genes encoding either voltage-gated or ligand-gated channels. The recognition that certain epilepsy syndromes are "channelopathies" initiates a new era in understanding the molecular pathophysiology of seizure disorders. This review summarizes recent advances related to this exciting area of investigation.
Personalized Privacy-Preserving Social Recommendation (2018)

Privacy leakage is an important issue for social recommendation. Existing privacy preserving social recommendation approaches usually allow the recommender to fully control users' information. This may be problematic since the recommender itself may be untrusted, leading to serious privacy leakage. Besides, building social relationships requires sharing interests as well as other private information, which may lead to more privacy leakage. Although sometimes users are allowed to hide their sensitive private data using privacy settings, the data being shared can still be abused by the adversaries to infer sensitive private information. Supporting social recommendation with least privacy leakage to untrusted recommender and other users (i.e., friends) is an important yet challenging problem. In this paper, we aim to address the problem of achieving privacy-preserving social recommendation under personalized privacy settings. We propose PrivSR, a novel framework for privacy-preserving social recommendation, in which users can model ratings and social relationships privately. Meanwhile, by allocating different noise magnitudes to personalized sensitive and non-sensitive ratings, we can protect users' privacy against the untrusted recommender and friends. Theoretical analysis and experimental evaluation on real-world datasets demonstrate that our framework can protect users' privacy while being able to retain effectiveness of the underlying recommender system.
Alain Moueix joue la biodynamique (2008)

In this work a new highly fluorescent N,N-dimethyl benzylamine-palladium(II) yu complex was synthesized by the reaction of [Pd<sub>2</sub> {(C,N-C<sub>6</sub> H<sub>4</sub> CH<sub>2</sub> N(CH<sub>3</sub> )<sub>2</sub> }<sub>2</sub> (μ-OAc)]<sub>2</sub> ] with curcumin. The structure of the synthesized complex was characterized using Fourier transform infra-red (FT-IR) spectroscopy, <sup>1</sup> H nuclear magnetic resonance spectroscopy, and elemental analysis. Fluorescence quantum yield (Φ<sub>F</sub> ) values of the synthesized complex in dimethyl sulfoxide (DMSO), acetonitrile, ethanol, and methanol were 0.160, 0.104, 0.068, and 0.061, respectively. The fluorescence signal of the complex in the organic solvents was very sensitive to the water content of the organic solvent. The quenching effect of water was used to determine trace amounts of water in the heteroatom-containing organic solvents (ethanol, methanol, acetonitrile) and redox-active solvents (DMSO). The linear ranges for determination of water (v/v %) in ethanol, DMSO and acetonitrile were found to be 0.03-14.5, 0.08-13.8, and 0.07-18.8, respectively. Two linear ranges were found for determination of water (v/v %) in methanol (0.1-1.2 and 4.7-25.0). Detection limit (DL) values were calculated to be 0.001, 0.05, 0.004, and 0.01 (v/v %) in ethanol, methanol, acetonitrile, and DMSO, respectively. The proposed method overcomes the problems of the standard Karl Fischer method for determination of water in DMSO. In addition, it gave the best DL value for determination of water in ethanol compared with all published papers to date.
A survey of research and development in distributed database management (1977)

We have shown recently that selegiline exerts a cardiac neuroprotective effect in chronic heart failure. Since selegiline has an antioxidant antiapoptotic effect, we proposed to determine whether selegiline attenuates cardiac oxidative stress and myocyte apoptosis in chronic heart failure by modulating Bcl-2 and Bax protein expression, and whether the effects are associated with the improvement of cardiac function. Rabbits with rapid cardiac pacing (360 beats/min) and sham operation without pacing were randomized to receive oral selegiline (1 mg/day) or placebo for 8 weeks. Echocardiography was used to measure left ventricular fractional shortening. After 8 weeks of treatment, animals were studied for arterial norepinephrine and left ventricular systolic function (fractional shortening and dP/dt), and were then sacrificed for measuring the stable oxidative product of myocardial mitochondrial DNA (mtDNA) 8-oxo-7,8-dihydro-2'-deoxyguanosine (8-oxo-dG), myocyte apoptosis by monoclonal antibody to single stranded DNA, and Bcl-2 and Bax protein expression by Western blot and immunohistochemistry. Rapid cardiac pacing increased plasma norepinephrine, cardiac oxidative stress and myocyte apoptosis, reduced Bcl-2 and the Bcl-2 to Bax ratio. These changes were associated with decreased left ventricular fractional shortening and dP/dt. Selegiline treatment in chronic heart failure animals reduced plasma norepinephrine, cardiac oxidative stress and myocyte apoptosis, prevented the changes of Bcl-2 and Bcl-2 to Bax ratio, and improved left ventricular fractional shortening and dP/dt. The findings suggest that the reduction by selegiline of myocyte apoptosis is related to the decrease of cardiac oxidative stress and the modulation of apoptotic and antiapoptotic proteins. The antioxidant antiapoptotic effects of selegiline are potentially beneficial in the improvement of cardiac function in chronic heart failure.
Rostros de la mujer ante el mundo indígena y la conquista (1995)

El rostro no es solo la cara, aspecto o especie. No es solamente lo que es visto; es tambien lo que ve. No solamente mirada sino unidad de la mirada y de la palabra, de los ojos y de la boca. Y sin embargo, la no es rosto mas que cara a cara. El rostro se da ahi simultaneamente como expresion y palabra. Su significacion es irreductible. Por lo demas, el rostro no significa. No encarna, no reviste, no senala a otra cosa que el mismo, alma, subjetividad, etcetera. El rostro no es una metafora, el rostro no es una figura. El rostro no se presenta como un signo sino que se expresa, dandose como persona, en si.  Este disparadero o disparatorio de ideas, de alguna manera muestra que la historia de los sistemas de pensamiento ha venido acumulando las expresiones sobre el rostro humano no solo a partir de la filosofia y la psicologia, sino tambien de la literatura: la novela, el teatro, el ensayo, el cuento y la poesia. Desde esta perspectiva, las anotaciones subsiguientes tenderian a explorar ciertas expresiones del rostro de la mujer en el ambito de la literatura del mundo indigena y de la Conquista, durante los siglos XVI y XVII, respectivamente.
Fiber Elongation and Dry Weight Changes in Mutant Lines of Cotton<sup>1</sup> (1974)

Genetic variation in fiber elongation and secondary cell wall deposition in cotton ( Gossypium hirsutum L.) was studied using three monogenic mutant lines ( Ligon lintless, Pilose , and immature fiber ) and two genetically diverse normal lines (Z2557 and Texas Marker‐1). Because it has been shown that secondary cell Wall deposition can begin before fiber elongation ceases, this experiment studied the genetic variability and interrelations between these two features of fiber development. The fiber development of these lines demonstrated that it is possible to alter, through genetic manipulation, either elongation or dry weight increase of the fibers without appreciably changing the other, thus demonstrating that fiber elongation and secondary cell‐wall deposition are not necessarily controlled by the same genetic factors.
Tracking direction of speaker for microphone array in the far field (2002)

This paper presents a method for tracking the direction-of-arrival (DOA) of a single speaker of interest in the far field for microphone arrays. The method can greatly enhance the effective power of the speaker based on a focusing transformation only for the speaker. The method is suitable for cases of low SNR or/and strong interfering signals. Computer simulations are given to support the proposed method.
A Requirement for Local Protein Synthesis in Neurotrophin-Induced Hippocampal Synaptic Plasticity (1996)

Two neurotrophic factors, brain-derived neurotrophic factor (BDNF) and neurotrophin-3 (NT-3), are able to produce a long-lasting enhancement of synaptic transmission in the hippocampus. Unlike other forms of plasticity, neurotrophin-induced plasticity exhibited an immediate requirement for protein synthesis. Plasticity in rat hippocampal slices in which the synaptic neuropil was isolated from the principal cell bodies also required early protein synthesis. Thus, the neurotrophins may stimulate the synthesis of proteins in either axonal or dendritic compartments, allowing synapses to exert local control over the complement of proteins expressed at individual synaptic sites.
Functionalization by Reductive Alkylation and Mapping of a Subbituminous Coal by Energy Dispersive X-ray Spectroscopy (2011)

Reduction of a subbituminous coal by lithium in liquid ammonia yields a coal salt that can be reacted with 1-iodododecane to yield dodecylated coal that is partially soluble in organic solvents. The coal salt also acts as an initiator for the in situ oligomerization of alkenes onto the surface of the coal nanoplatelets. Atomic force microscopy and high-resolution transmission electron microscopy images of this material have been recorded. Energy-dispersive X-ray spectroscopy has been used to identify minerals that occur in the coal.
Evidence of deteriorating semen quality in the United Kingdom: birth cohort study in 577 men in Scotland over 11 years (1996)

Time-Modulation of Linear Arrays for Real-Time Reconfigurable Wireless Power Transmission (2016)

This paper proposes a smart wireless power transmission method, based on a two-step procedure, exploiting real-time beaming of time-modulated arrays. The sideband radiation phenomenon, which is usually a drawback of these radiating systems, is favorably used for intentional wireless power transfer (WPT): in a first step to precisely localize the tag to be powered and in the second one to perform directive WPT. The approach is first theoretically discussed, then the numerical procedure, which integrates full-wave analysis of the antenna array with nonlinear simulation of the modulated nonlinear feeding network, is used to validate the principle of operation and to include nonlinearities and electromagnetic couplings affecting the whole system performance. The procedure allows a flexible design of the time-modulated-array-based WPT system, taking into account the impact of different array elements layout and spacing on localization and power transmission performance. Experiment of the first step is carried out in a real indoor environment at 2.45 GHz: a TI MSP430 drives a Schottky-diode-based network to provide proper modulated RF excitations of the array elements. Measurements show that the system is able to select tags to be energized randomly distributed in a 100 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">°</sup> -scanning range.
