Radio resource management in wireless LANs (2004)

Some chief information officers and information technology managers are reluctant to deploy wireless LANs. Among their concerns are reliability, availability, performance, and deployment. Each of these concerns can be directly addressed through the radio resource management techniques used in a new generation of wireless LAN equipment. The new capabilities include dynamic channel assignment, dynamic power control, and load sharing. Changing from the relatively static radio resource management techniques generally in use today to dynamic methods like those highlighted in this article helps to increase the capacity and improve the performance of large-scale wireless LANs.
Polymorphisms in Protein Tyrosine Phosphatase Non-receptor Type 2 and 22 (PTPN2/22) Are Linked to Hyper-Proliferative T-Cells and Susceptibility to Mycobacteria in Rheumatoid Arthritis (2018)

A shared genetic pre-disposition, chronic inflammation, and treatment with similar biologics between Rheumatoid arthritis (RA) and Crohn's disease (CD) have intrigued us to investigate whether the two disorders share trigger association or possible causation. We hypothesized earlier that Single Nucleotide Polymorphisms (SNPs) in the negative regulators <i>Protein Tyrosine Phosphatase Non-receptor type 2 and 22</i> (<i>PTPN2/22)</i> lead to a dysregulated immune response, susceptibility to environmental triggers, and continued apoptosis as seen in chronic inflammation in RA and CD. To test the hypothesis, peripheral leukocytes samples from 132 consented subjects were genotyped for 9 SNPs in <i>PTPN2</i>/22 using TaqMan™ genotyping. The effect of the SNPs on <i>PTPN2</i>/22 and <i>IFN-</i>γ expression was determined using real time PCR. T-cell proliferation and response to phytohematoagglutonin (PHA) mitogen and mycobacterial antigens were determined by BrdU proliferation assay. Blood samples were also analyzed for the <i>Mycobacterium avium</i> subspecies <i>paratuberculosis</i> (MAP) <i>IS900</i> gene by nPCR. Out of 9 SNPs examined, heterozygous (TC) or minor (CC) alleles of <i>PTPN2</i>:<i>rs478582</i> occurred in 79% RA compared to 60% healthy controls (<i>p</i>-values ≤ 0.05; OR = 2.28). Similarly, heterozygous (GA) or minor (AA) alleles of <i>PTPN22:rs2476601</i> occurred in 29% RA compared to 6% healthy controls (<i>p</i>-values ≤ 0.05; OR = 5.90). <i>PTPN2/22</i> expression in RA was decreased by 1.2-fold compared to healthy controls. <i>PTPN2:rs478582</i> upregulated <i>IFN-</i>γ in RA by 1.5-fold. Combined <i>PTPN2:rs478582</i> and <i>PTPN22:rs2476601</i> increased T-cell proliferation by 2.7-fold when treated with PHA. Surprisingly, MAP DNA was detected in 34% of RA samples compared to 8% healthy controls, (<i>p</i>-values ≤ 0.05, OR = 5.74). RA samples with <i>PTPN2:rs478582</i> and/or <i>PTPN22:rs2476601</i> were more positive for MAP than samples without polymorphisms. Combined occurrence of <i>PTPN2:rs478582</i> and <i>PTPN22:rs2476601</i> in association with the presence of MAP has significantly increased T-cell response and elevated <i>IFN-</i>γ expression in RA samples. The data suggest that genetic polymorphisms may play vital role in T-cell regulation, susceptibility to mycobacteria and ultimately response to treatment. This is the first study to report the detection of MAP DNA in the blood of RA patients; further studies are needed using larger number of samples.

Bacillus siamensis sp. nov., isolated from salted crab (poo-khem) in Thailand (2009)

A Gram-positive, endospore-forming, rod-shaped bacterium, strain PD-A10(T), was isolated from salted crab (poo-khem) in Thailand and subjected to a taxonomic study. Phenotypic and chemotaxonomic characteristics, including phylogenetic analyses, showed that the novel strain was a member of the genus Bacillus. The novel strain grew in medium with 0-14 % (w/v) NaCl, at 4-55°C and at pH4.5-9. The predominant quinone was a menaquinone with seven isoprene units (MK-7). The major fatty acids were anteiso-C₁₅:₀ and anteiso-C₁₇:₀. Polar lipid analysis revealed the presence of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, lysylphosphatidylglycerol, glycolipid and unknown lipids. The DNA G+C content was 41.4 mol%. The 16S rRNA gene sequence similarities between strain PD-A10(T) and Bacillus amyloliquefaciens NBRC 15535(T), Bacillus subtilis DSM 10(T), Bacillus vallismortis DSM 11031(T) and Bacillus mojavensis IFO 15718(T) were 99.5, 99.4, 99.4 and 99.2 %, respectively. Strain PD-A10(T) showed a low degree similarity of rep-PCR fingerprints and low DNA-DNA relatedness with the above-mentioned species. On the basis of the data gathered in this study, strain PD-A10(T) should be classified as representing a novel species of the genus Bacillus, for which the name Bacillus siamensis sp. nov. is proposed. The type strain is PD-A10(T) (=BCC 22614(T)=KCTC 13613(T)).
Clinical prognostic factors in lupus nephritis. The importance of hypertension and smoking (1992)

<h3>Background.—</h3> Many previous studies of the influence of sociodemographic and clinical factors on the development of renal failure in patients with lupus nephritis have been based on selected subgroups of patients and have yielded conflicting results. We sought to determine the prognostic importance of patient demographic characteristics (age, gender, race, and socioeconomic status), smoking status, and hypertension in the development of end-stage renal disease (ESRD) among patients with lupus nephritis. <h3>Methods.—</h3> This retrospective cohort study followed an inception cohort of 160 adults with lupus nephritis. The outcome measure was the development of ESRD, defined as the institution of maintenance dialysis or measurement of a creatinine clearance of 10 mL/min or less. Life-table analysis was used to determine differences between patient subgroups in the time to development of ESRD. <h3>Results.—</h3> End-stage renal disease developed in 41 (26%) of 160 patients followed up for a median of 6.4 years. Hypertension and smoking status at the onset of nephritis were strongly associated with differences in the time to development of ESRD. The median time to ESRD among patients with moderate to severe hypertension (diastolic blood pressure, ≥105 mm Hg) was 7 months, among patients with mild hypertension (diastolic blood pressure, 90 to 104 mm Hg) it was 146 months, and among normotensive patients it was greater than 273 months.The median time to ESRD among smokers was 145 months and among nonsmokers it was greater than 273 months. These effects persisted in multivariable analyses adjusting for differences among patients in age, gender, socioeconomic status, renal histology, and immunosuppressive treatment. The independent effects of hypertension and smoking resulted in shorter times to renal failure among patients who were both hypertensive and smoking, compared with nonsmoking hypertensive patients. The development of ESRD did not differ among patient demographic subgroups. <h3>Conclusion.—</h3> Patient demographic characteristics had no detectable impact on the rate of progression to ESRD in this cohort. Hypertension and smoking appear to be important, potentially modifiable, factors influencing the prognosis of patients with lupus nephritis. (<i>Arch Intern Med</i>. 1992;152:2082-2088)
Live Imaging of Mouse Endogenous Neural Progenitors Migrating in Response to an Induced Tumor (2012)

Adult neurogenesis is restricted to specific brain regions. Although involved in the continuous supply of interneurons for the olfactory function, the role of neural precursors in brain damage-repair remains an open question. Aiming to in vivo identify endogenous neural precursor cells migrating towards a brain damage site, the monoclonal antibody Nilo2 recognizing cell surface antigens on neuroblasts, was coupled to magnetic glyconanoparticles (mGNPs). The Nilo2-mGNP complexes allowed, by magnetic resonance imaging in living animals, the in vivo identification of endogenous neural precursors at their niche, as well as their migration to a lesion site (induced brain tumor), which was fast (within hours) and orderly. Interestingly, the rapid migration of neuroblasts towards a damage site is a characteristic that might be exploited to precisely localize early damage events in neurodegenerative diseases. In addition, it might facilitate the study of regenerative mechanisms through the activation of endogenous neural cell precursors. A similar approach, combining magnetic glyconanoparticles linked to appropriate antibodies could be applied to flag other small cell subpopulations within the organism, track their migration, localize stem cell niches, cancer stem cells or even track metastatic cells.
Irradiance moments: their propagation and use for unique retrieval of phase (1982)

The functional dependence of irradiance moments with distance from the pupil plane is studied within the framework of Fresnel diffraction theory. The concept of analytic pupil function is introduced, and for such pupil functions it is shown that any finite-order irradiance moment exists, even in the presence of arbitrary continuous phase aberrations. The uniqueness of the relationship between pupil-plane phase and irradiance moments, when the moments are calculated over an orthogonal plane at a fixed point along the optical axis in image space, is obscure, and the relationship between phase and moments is generally nonlinear. However, by studying the behavior of irradiance moments throughout the neighborhood of a given axial point in image space, one may determine, for a large class of pupils, the pupil-plane phase uniquely (within an arbitrary additive constant), and only a linear problem need be solved for phase retrieval. In particular, unique phase retrieval may be accomplished by measuring moments in the neighborhood of either the pupil plane or the image plane. Examples of this technique are given.
Ion beam irradiated via-connect through an insulating polymer layer (1984)

Ion beams can render a polymer film conductive (ρ∼3×10−3 Ω cm measured by a four-probe technique). Using this effect we show that an insulating polymer layer used as an isolating layer between two conducting layers can be electrically shorted by heavy ion beam irradiation. This technique, besides enabling a measurement of the resistivity in the orthogonal direction, demonstrates the feasibility of using a polymer as an insulating layer with a direct via-connect produced across it by ion beam irradiation. The measured resistivities perpendicular (ρ⊥ ) and parallel (ρ∥ ) to the film plane within experimental measurements show that ion-beam induced conductivity in these films is isotropic. The isotropy of the conductivity suggests nonspecular scattering of the carriers in these disordered films.
All-optical clock recovery from NRZ data of 10 Gb/s (1999)

We demonstrate successfully an all optical clock recovery scheme based on all-fiber devices from nonreturn-to-zero format data of 10 Gb/s with a stabilized asymmetric Mach-Zehnder interferometer and a mode-locked erbium-doped fiber laser. This all-optical clock recovery method will find application in ultrahigh-speed all-optical communication systems.
Molecular mechanism of DNA association with single-stranded DNA binding protein (2017)

During DNA replication, the single-stranded DNA binding protein (SSB) wraps single-stranded DNA (ssDNA) with high affinity to protect it from degradation and prevent secondary structure formation. Although SSB binds ssDNA tightly, it can be repositioned along ssDNA to follow the advancement of the replication fork. Using all-atom molecular dynamics simulations, we characterized the molecular mechanism of ssDNA association with SSB. Placed in solution, ssDNA-SSB assemblies were observed to change their structure spontaneously; such structural changes were suppressed in the crystallographic environment. Repeat simulations of the SSB-ssDNA complex under mechanical tension revealed a multitude of possible pathways for ssDNA to come off SSB punctuated by prolonged arrests at reproducible sites at the SSB surface. Ensemble simulations of spontaneous association of short ssDNA fragments with SSB detailed a three-dimensional map of local affinity to DNA; the equilibrium amount of ssDNA bound to SSB was found to depend on the electrolyte concentration but not on the presence of the acidic tips of the SSB tails. Spontaneous formation of ssDNA bulges and their diffusive motion along SSB surface was directly observed in multiple 10-µs-long simulations. Such reptation-like motion was confined by DNA binding to high-affinity spots, suggesting a two-step mechanism for SSB diffusion.
Mixed brenner and adenomatoid tumor of the testis.An ultrastructural study and histogenetic considerations (1979)

A previously unreported association of Brenner and adenomatoid tumor found in the tunica vaginalis testis is presented. Many ultrastructural features found in mesothelial cells such as intercellular spaces, deeply indented nuclei, tonofilaments and tight desmosomes, were also shared by cells present in both neoplastic patterns. The previous histogenetic origins ascribed to testicular Brenner tumors are discussed and the evidence for their origin in the mesothelium considered.

Nutraceuticals in the Prevention of Viral Infections, including COVID-19, among the Pediatric Population: A Review of the Literature (2021)

In recent years, there has been a growth in scientific interest in nutraceuticals, which are those nutrients in foods that have beneficial effects on health. Nutraceuticals can be extracted, used for food supplements, or added to foods. There has long been interest in the antiviral properties of nutraceuticals, which are especially topical in the context of the ongoing COVID-19 pandemic. Therefore, the purpose of this review is to evaluate the main nutraceuticals to which antiviral roles have been attributed (either by direct action on viruses or by modulating the immune system), with a focus on the pediatric population. Furthermore, the possible applications of these substances against SARS-CoV-2 will be considered.
Correlation between Milk and Dairy Product Consumption and Multiple Sclerosis Prevalence: A Worldwide Study (1992)

Multiple sclerosis (MS) epidemiology suggests that different factors are involved in the clinical expression of the disease. Alimentary cofactors have already been considered, but mainly theoretically. We have studied the relationship between MS prevalence and dairy product consumption in 27 countries and 29 populations all over the world, with Spearman's correlation test. A good correlation between liquid cow milk and MS prevalence (rho = 0.836) was found; this correlation was highly significant (p < 0.001). A low but still significant correlation was obtained with cream or butter consumption (rho = 0.619 and rho = 0.504, respectively). No correlation was found for cheese. These results suggest that liquid cow milk could contain factor(s) - no longer present in the processed milk - influencing the clinical appearance of MS. The possible role of some dairy by-products is discussed in the light of a multifactorial etiology of MS.
An Implementation of Number Plate Recognition without Segmentation Using Convolutional Neural Network (2017)

Automatic number plate recognition (ANPR) is a significant part in intelligent traffic system. At present, there are many traditional approaches that have achieved a rather high accuracy to solve this problem, almost all of which are separated into three steps of localization, segmentation and recognition. However, these approaches, especially in segmentation progress, are limited to some specific conditions including light intensity, orientations, rotation and distortion angle of plates, etc. In this paper, distinct from traditional approaches, a network including a convolutional neural network(CNN) that operates directly on the image pixels is employed as a substitute of the integration of segmentation and recognition. The network works on the TensorFlow framework. Evaluation of this training network is characters' recognition accuracy on a test set of 796 number plate pictures. In result, we achieve a 88.61% accuracy with a training set of only 7396 photographs that are expanded from 3041 different number plate pictures, which is a relatively high accuracy, especially for a deep CNN that usually needs a great number of samples. We also demonstrate one possible way to enrich data set and make a test using a even simpler network, which results in a 90.07% accuracy on a test set.
The kinetics of dissolution of enargite in acidified ferric sulphate solutions (1972)

AbstractOver the temperature range 60° to 95°C, sintered discs of synthetic enargite (Cu3AsS4) were dissolved slowly in acidified ferric sulphate solutions, yielding both elemental and sulphate sulphur, together with soluble copper and arsenic. The dissolution kinetics were linear and this was interpreted as indicating rate control by a reaction occurring on the surface of this sulphosalt. The activation energy associated with this reaction was 13.3 kcal/mole. The rate of copper extraction increased according to the 0.55 power of the ferric sulphate concentration and the 0.20 power of the sulphuric acid concentration. The rate decreased in a complex manner with increasing strengths of the ferrous sulphate reaction product. Natural enargite dissolves like the synthetic sulphosalt and at approximately the same rate. Résumé A des températures variant entre 60°C et 95°C, des disques frittés d'énargite synthétique (Cu3AsS4) ont été dissous lentement dans des solutions acides de sulfate ferrique, pour produire du soufre élémentaire et sous forme de sulfate, ainsi que du cuivre et de l'arsenic soluble. Les cinétiques de dissolution suivent une loi linéaire, due à la réaction qui a lieu en surface de ce sulfosel et qui, semble-t-il, contrôlerait la dissolution. L'énergie d'activation associée à la réaction est de 13.3 kcal/mole. Le taux d'extraction du cuivre croît comme la puissance 0.55 de la concentration en sulfate ferrique et la puissance 0.20 de la concentration en acide sulfurique. La vitesse décroît de façon complexe lorsque augmente la concentration du produit de la réaction du sulfate ferreux. L'énargite naturelle se dissout de la même manière que le sulfosel synthétique, et à sensiblement la même vitesse.
Plant mitochondria : structural, functional, and physiological aspects (1987)

Eight years have elapsed since the first International Meeting on Plant Mitochondria was held in Marseilles. Since this date numerous important developments have occurred within the field and hence a further conference on this fundamental area of research was considered well overdue. This volume summarises the lecture and poster sessions of the second International Meeting on Plant Mitochondria held in Aberystwyth, July 20- 24th, 1986. The meeting was held not only to bring together plant scientists interested in the bioenergetics of plant mitochondria but also those who are interested in the regulatory role of mitochondria in plant growth and respiration. A further important aspect of this conference was to introduce plant physiologists and biochemists to the plant molecular biologists in an attempt to not only discuss problems of mutual interest but to also learn much more about the real questions which the biochemists and physiologists wish to answer. Hopefully the volume reflects much of the current excitement and advances being made in the field. Although many of the participants of the first meeting were present the expertise of Walter Bonner, Jack Hanson and Gaston Ducet, to name but a few, was sorely missed. The conference consisted of forty-five minute review lectures followed by thirty minute research lectures, the summaries of which are found in the longer articles. The meeting was divided into four seSSions, namely, organisation of the electron transport chain; mitochondrial interactions; mitochondrial biogenesis and plant growth and development.
A comparison of balloon- and self-expanding stents (2002)

This paper summarizes some of the key differences between self-expanding and balloon-expanding stents, aligning engineering and design differences with clinical performance. While neither type of stent can be considered universally superior, the differences are significant enough to make each type more appropriate in specific circumstances. Many of the differences concern long-term outcome, for which there is still insufficient data.
Desktop virtual studio system (1996)

We have been developing a desktop virtual studio (DVS) that allows video producers to create various studio shots on a desktop work space as if those are shot in a real studio. Electronically generated or stored sets, actors, and a camera are integrated in a virtual workspace, and producers can manipulate them through specially designed man-machine interfaces. Our prototype DVS system can realize virtual shooting where two prerecorded actors are performing in virtual sets generated by real-time computer graphics. We discuss the prototype DVS and its application to desktop program production (DTPP).
