An approach for just-in-time radio access network capacity planning in CDMA networks (2008)

This paper describes a holistic capacity planning methodology for radio access networks (RANs) and presents a case study focusing on the third generation (3G) code division multiple access (CDMA) technology. It addresses the complex problem of how a RAN should be optimally and just-in-time equipped to accommodate fluctuations in traffic patterns over time, while fulfilling the quality of service (QoS) requirements of a wireless network operator (WNO) and without over-provisioning. The just-in-time RAN capacity planning methodology provides a software engine that automatically and iteratively computes various RAN configurations (which may correspond to various “what-if” deployment scenarios) based on multiple inputs that include network configuration, traffic volume measurements, and traffic forecast. It uses a bottom-up approach that sequentially evaluates the capacity needs over the air interface, at the base stations, and over the transport (backhaul) domain. Material in excess/deficit is identified at each RAN level and may be redistributed to avoid ordering of new material and reduce overall cost. This methodology provides the rapid and repeatable dimensioning which is required to implement just-in-time provisioning processes, and to support the network cost modeling an operator requires to quickly model quality of service and call plan strategy. Furthermore, thanks to its high level of automation, it allows the WNOs to complete a multi-year capacity planning process quickly and efficiently. The approach uses a generic process enabling its applicability to any CDMA-based network. It has been intensively tested with real field data and has been recently adopted by several WNOs.
The cytotoxicity of serum for mouse mammary cancer cells. II. The effects upon cells in culture. (1954)

Summary A cytotoxic study on mouse mammary cancer cells was made by utilizing the tissue culture technic. Mouse mammary cancer cells in culture were severely damaged by exposure for from 3 to 6 hours to samples of guinea pig antiserum representative of tissues known to contain the mammary tumor virus. The exposure under similar conditions of cultures to normal guinea pig serum or to antiserum representative of tissues lacking the tumor virus did not damage the cells. Control cultures of embryonic mouse intestines and of strain HeLa, of human malignant epithelial cells, were not damaged by various samples of antiserum. An attempt to produce cytotoxic antibodies in a resistant strain of the same species was unsuccessful.
Effects of indomethacin and dexamethasone on mechanical scratching‐induced cutaneous barrier disruption in mice (2006)

Effects of indomethacin and dexamethasone on recovery of cutaneous barrier disruption induced by mechanical scratching were examined. Cutaneous barrier was disrupted by scratching using a stainless-steel wire brush (mechanical scratching) and compared to cutaneous application of acetone/ether (1:1) mixture (AE) and tape-stripping. Increase of transepidermal water loss (TEWL), as an indicator of a broken skin barrier, and recovery period for mechanical scratching were higher and longer than those for AE treatment and tape-stripping and we also confirmed the severity of skin damage in a histological study. Topical application of moisturizers showed a temporal effect, rapidly decreased TEWL on mechanical scratching- or AE treatment-induced cutaneous barrier disruption, and gradually increased base levels from 4 to 12 h after treatment. Topical application of indomethacin or dexamethasone prolonged the recovery period for the cutaneous barrier, and concomitant use further worsened the status of the barrier. Additionally, we examined the effects of prostaglandins (PGs) and inflammatory cytokine on mechanical scratching-induced cutaneous barrier disruption pretreated with indomethacin and dexamethasone. As a results, PGD2 and interleukin (IL)-1beta significantly accelerated the recovery of cutaneous barrier disruption by mechanical scratching but such was not the case with PGE2, IL-1alpha, and tumor necrosis factor-alpha treatment. These results suggest that indomethacin and dexamethasone prolonged the recovery period caused by inhibition of PGD2 and IL-1beta. Mechanical scratching-induced cutaneous barrier disruption may be a useful method for evaluating means of recovery from skin damage.
Sequence analysis of the downstream 5' nontranslated region of seven echoviruses with different neurovirulence phenotypes (1995)

The downstream 5' nontranslated regions of seven echoviruses with different neurovirulent phenotypes were amplified and sequenced. Neurovirulent echovirus serotypes 4, 6, 9, 11, and 30 were identical to the putative poliovirus in 18S rRNA binding sequence and the flanking conserved sequences. Less neurovirulent echoviruses, serotypes 2 and 12, exhibited variations within these regions.
Structure-Solubility Relationships in Coal, Petroleum, and Immature Source-Rock-Derived Asphaltenes (2020)

Five asphaltene samples from three different source types–immature source rock (ISA), petroleum (PA), and coal (CDA)–are studied using integrated chemical and spectroscopic techniques (elemental analysis, 13C magnetic resonance spectroscopy, infrared spectroscopy, and X-ray spectroscopy) to understand their chemical compositions, molecular architectures, and structure-solubility relationships. The three asphaltene classes are found to have grossly different compositions, reflecting their source. ISA that have experienced little-to-no catagenesis have the highest aliphatic carbon content, lowest aromatic carbon content, and high polar heteroatom (sulfoxide-sulfur) content. PA from reservoir crude oils have higher aromatic carbon content and largely nonpolar heteroatom (thiophene-sulfur) content. CDA have the highest aromatic carbon content and low total sulfur content. Despite these compositional differences, all asphaltenes maintain the required strength of intermolecular interactions according to their solubility definition. However, the three types of asphaltenes are found to achieve the same intermolecular interaction in different ways. CDA have strong π–π stacking between their PAH cores with little steric disruption from aliphatic structures, indicating intermolecular interactions dominated by polarizability. PA also have strong π–π stacking but with enhanced disruption from their larger number and size of aliphatic structures on PAH clusters. Enhanced polarizability may exist in PA via dispersion forces due to the larger molecular weight of PA versus CDA. By comparison, ISA have relatively weak π–π stacking owing to their smaller PAH and increased steric disruption from abundant aliphatic carbon. This reduced strength of polarizability interactions in ISA is compensated by the presence of polar moieties (sulfoxide and carbonyl) that enhance dipole–dipole and/or dipole–induced dipole interactions. These interpretations are consistent with measured planarity of single asphaltene molecules and with molecular mechanics modeling of asphaltene nanoaggregate structures. These observations of same solubility yet different composition among asphaltene classes can be understood with respect to Hansen solubility parameters for which polarizability is the dominating force between asphaltene molecules.
Temperature tuning of 1.3 m vertical-cavity semiconductor optical amplifiers (2003)

In this study we demonstrate the temperature tuning of a 1.3µm Vertical-Cavity Semiconductor Optical Amplifier. We achieved 10dB of fiber-to-fiber gain over a tuning range of approximately 8 nm.
Guiding of Argon ions through PET nano capillary foils (2009)

The transmission of charge state separated slow ions through nano capillaries with an aspect ratio of 1/100 in insulating polyethylene terephthalate (PET) polymers was investigated on argon ions with different charge states from Ar3+ up to Ar12+. The experiments were performed with a beam line featuring an ion deceleration system. With it the ion guiding of projectiles of different kinetic energies ranging from 600eV up to 9.6 keV has been studied. The guiding power as well as the divergence angle of the transmitted ion beam have been investigated in dependence on the initial ion charge state and the ion energy. A scaling of the profile width tan σϕ ≈ √q at a constant ion energy was found. Furthermore, the guiding angle was measured as independent on the ion charge state at an ion energy scaling with the ion charge state.
Stiffness Comparison of Coracoclavicular Ligament and Anatomic Reconstruction Complexes: Overall and Individual Complex Components (2003)

The stiffness of the coracoclavicular ligaments and their surgical replacments have previously been reported; however, the mechanism of failure and procedures for repair include both the clavicle and coracoid process which have not been investigated. Therfore, this study utilized a physiolgogic mechanism of injury to compare the stiffness of the coracoclavicluar ligament and anatomic reconstruction complexes, both overall and individual complex components. After dislocation of the coracoclavicular ligament complex, a 40% decrease of the clavicle stiffness was observed along with a more comparable stiffness of the reconstruction tendon graft to the intact coracoclavicular ligaments compared to current repair materials. These findings suggest all components of the coracoclavicluar complex following dislocation should be considered in selection of rehablilation protocols or surgical procedures.
The serum concentration of prolactin is suppressed and corticosterone is elevated in male rats following sublethal burn injury (2000)

To improve the current clinical protocols used after a burn injury, injections of anabolic hormones like growth hormone (GH) or prolactin (PRL), which are also known to be immunostimulators has been suggested (Knox et al., 1995). Glucocorticoids, GH and PRL are considered stress hormones because their secretion is strongly altered by exposure to environmental stressors. Consistent with this concept, previous studies have suggested that the circulating levels of each of these hormones is increased by 24 h after a burn injury. However, the patterns of their secretion during the first hours after the burn injury is less well known. Working on male Sprague-Dawley rats, we have investigated the levels of corticosterone (CS) and PRL in the first hours after burn injury. Male rats were divided in three groups: 1) no treatment and no handling before execution (this allowed us to monitor the normal circadian cycle of the hormones); 2) rats are anesthesised using pentobarbitol, shaved and prepared for the burn, but not burned (sham-treated animals); 3) rats anesthesised and burned at 8AM. The rats were thereafter sacrified at specific times (day 1: 9AM, 10AM, 12PM, 4PM, 7PM; day 2: 8AM, 9AM, 10AM, 4PM, 7PM). Plasma was collected and the serum levels of CS and PRL were measured by ELISA and RIA, respectively. The circadian cycle of CS showed the predicted nadir at 10AM, and peak at 4PM. CS levels were elevated 6-fold by 1h after burn injury, reaching a maximum at 600ng/ml at 10AM. The concentration was progressively reduced to normal levels by 6 h after the burn injury, and followed the normal pattern thereafter. In sham-treated animals, CS concentration was similar to the burned animals, but the maximum elevation was only 3-4-fold, and the return to normal concentration was faster, after only 4 hours. The normal circadian cycle of PRL peaked at 8AM (110ng/ml) at 8AM. In contrast to CS, serum PRL fell dramatically following burn injury to less than 20ng/ml, and stayed low for 4h folowing the burn injury. In sham-treated animals, the changes in PRL were similar, but less dramatic than in the burned animals. In conclusion anesthesia and burn stress have similar effects on hormone secretion, but burn represents a stronger stressor. In the immediate hours following burn injury the animal physiology is dominated by high levels of secretion of an immunosuppressor (CS) and low levels of a potential immunostimulator (PRL).
The Positive Effects of Negative Work: Increased Muscle Strength and Decreased Fall Risk in a Frail Elderly Population (2003)

These data demonstrate that lower extremity resistance exercise can improve muscle structure and function in those with limited exercise tolerance. The greater strength increase following negative work training resulted in improved balance, stair descent, and fall risk only in the ECC group. Because low energy cost is coupled to high force production with eccentric exercise, this intervention may be useful for a number of patients that are otherwise unable to achieve high muscle forces with traditional resistance exercise.
Slow-Down Collisions and Nonsequential Double Ionization in Classical Simulations (2002)

We use classical simulations to analyze the dynamics of nonsequential double-electron short-pulse photoionization. We utilize a microcanonical ensemble of 10(5) two-electron "trajectories," a number large enough to provide large subensembles and even sub-subensembles associated with double ionization. We focus on key events in the final doubly ionized subensemble and back-analyze the subensemble's history, revealing a classical slow-down scenario for nonsequential double ionization. We analyze the dynamics of these slow-down collisions and find that a good phase match between the motions of the electrons can lead to very effective energy transfer, followed by escape over a suppressed barrier.
The hemolytic effect of primaquine. III. A study of primaquine-sensitive erythrocytes. (1954)

Abstract The erythrocytes of primaquine-sensitive and nonsensitive individuals not receiving primaquine have been compared in the following respects: (a) morphology; (b) antigenic characteristics; (c) sensitivity to acid hemolysis; (d) hemoglobin type; (e) mechanical, osmotic, and chemical fragility; (f) the fragility to the in vitro hemolytic action of primaquine, pamaquine, 6-methoxy-quinoline, quinoline, and aniline; and (g) susceptibility to the accelerating effect of naphthalene and primaquine on taurocholate or saponin hemolysis. The morphology, Coombs' tests, hemoglobin type, and osmotic and mechanical fragility of the erythrocytes have also been studied during the various phases of the hemolytic reaction.
Leisure activities of middle aged and older widowed adults (2007)

This study examined leisure differences between middle aged (40-59 years old) and older (60-69 years old) widowed adults. The sample consisted of 453 adults (midlife group, n=210; older group, n=243). The current study is a secondary analysis of data collected for the American Association for Retired Persons (AARP). The MANOVA revealed that there were leisure differences between the two groups. Univariate follow-up tests revealed that the middleaged group more frequently engaged in (a) visited family, (b) engaged in hobbies, (c) read, (d) watched T.V., (e) did volunteer work, and (f) spiritual activities. In contrast, older adults more frequently played with pets. There were no group differences in time spent with friends. Thus, the middle-aged group was more different than similar to the older group in their leisure activities. The potential meaning of the results are interpreted through family development theory. Widowed leisure is worthy of more empirical attention. More specifically, future research can identify other resources (e.g., time), limitations (e.g., housing, transportation) and benefits of leisure for these middle-aged and older adults.
Lymphocyte and markers of inflammation detection in the conjunctival epithelium of patients with dry eye by enhanced flow cytometry (2009)

Abstract Purpose The aim of our study was to test the hypothesis that the use of cell culture medium can increase the number of cells obtained by impression cytology (IC) sampling of the conjunctiva in dry eye patients, and make the analysis of epithelial and lymphocyte cell populations with flow cytometry possible. Methods IC specimens were collected in 15 normal subject and 15 dry eye patients. Samples collected from the right eye were placed in cell culture medium containing 10% foetal calf serum (FCS), and samples from the left eye in Phosphate Bufferred Saline containing 0.05% paraformaldehyde (PFA). The number of cells was analyzed by flow cytometry in both groups. Samples collected from a group of 30 dry eye patients were placed in FCS and stained for the expression of CK19, CD45, CD3, HLA‐DR, and analyzed by flow cytometry. A control group of 10 subjects was used as control. Results The number of cells counted in the FCS samples was statistically increased in the normal (12791 ± 11350 events per minute) and dry eye group (23468 ± 15596) when compared to PFA samples (2031 ± 2336, and 2608 ± 1814 respectively). In dry eyes the low number of cells in PFA samples made possible only the analysis of HLA‐DR expression, while in FCS samples epithelial (CK19+), leukocyte (CD45+), and lymphocyte (CD3+) cell populations were characterized, other than analyzed for HLA‐DR expression. Conclusion This study indicates that using this new method of preservation can enhance flow cytometry analysis of epithelial and immune cells of the conjunctiva in dry eye patients, opening new scenarios in the comprehension of its pathogenesis and in testing new therapies.
Échangeurs à condensation en matériau polymère (1989)

L'échangeur gaz-gaz en matériau polymère, développé conjointement par la Société d'Équipements Thermiques et de Récupérateurs Métalliques (SETREM) et l'Institut Français du Pétrole (IFP), fait ici l'objet d'une description de son principe de base et des méthodes de modélisation développées par I'IFP. Le caractère modulaire de sa conception et les avantages spécifiques des matériaux polymères (inertie chimique, mise en oeuvre aisée, non adhérence des salissures, légèreté) constituent les principaux arguments des développements potentiels de cet échangeur. Parmi ceux-ci figure la récupération sur fumées de chaudière alimentée en fuel lourd n°2 dont l'intérêt a été démontré sur un prototype essayé au Centre d'Études et de Développement Industriels de I'IFP. Il est également fait état de la première application effective de cet échangeur pour la déshumidification des fumées issues de chaudières à gaz à condensation. On évite ainsi le tubage des conduits de fumées qui constitue un obstacle économique majeur à la diffusion de telles installations en chauffage collectif. Sont présentées enfin les caractéristiques d'un échangeur de ce type (surface d'échange : environ 5000 m²) assurant le séchage d'air humide dans une application du secteur agroalimentaire en cours de projet.

The mission of Dr. Markey's Biomedical Informatics Lab is to develop decision support systems for clinical decision making and scientific discovery. For example, Prof. Markey leads a collaborative, multiinstitutional team that is designing a decision support system to help breast cancer survivors understand their likely appearance changes following breast reconstruction and, therefore, enable them to choose a reconstruction strategy that will lead to maximal psychosocial adjustment.
Ion milling properties of laterally emitting thin-film electroluminescent materials (2001)

A study has been undertaken of the ion milling properties of ZnS:Mn, Y/sub 2/O/sub 3/, Si/sub 3/N/sub 4/, SiO/sub 2/, SiO/sub x/N/sub y/, and Al versus the etching time, the acceleration voltage, and the angle of incidence of the ion beam. Different ZnS:Mn etched profiles have been fabricated by modifying the angle of incidence; these are in agreement with the reported simulations.
High Stability Aggregation Obtained Using Hydrophilic-Hydrophobic Block Copolymer Based on Poly(trimethylene carbonate) (2012)

Biodegradable polymers can be used in living systems. One such biodegradable polymer that has attracted considerable attention in recent years is poly(trimethylene carbonate) (PTMC). In this study, poly(ethylene glycol) monomethyl ether (mPEG), which has hydrophilic properties, was used as the initiator for PTMC synthesis. The mPEG-PTMC block copolymer exhibits amphiphilicity and forms a very stable aggregation in a solvent. In our previous study, mPEG-PTMC aggregations that remained stable for two months in a methanol solvent were prepared. In the present study, the aggregation of this polymer could be maintained in a stable state for 1 year in ultrapure water owing to the hydrophilic segment of mPEG. Additionally, examination of the encapsulation properties of the aggregation was also performed using 8-anilino-1-naphthalenesulfonic acid. Encapsulation of the aggregation caused the intensity of the fluorescence to become high and the maximum fluorescence wavelength to shift to the short wavelength resion with increasing polymer concentration. The high stability and encapsulation property of this aggregation will facilitate application of this polymer to drug delivery systems.
Crystallization and preliminary X-ray diffraction analysis of protein 14 from<i>Sulfolobus islandicus</i>filamentous virus (SIFV) (2006)

A large-scale programme has been embarked upon aiming towards the structural determination of conserved proteins from viruses infecting hyperthermophilic archaea. Here, the crystallization of protein 14 from the archaeal virus SIFV is reported. This protein, which contains 111 residues (MW 13 465 Da), was cloned and expressed in Escherichia coli with an N-terminal His(6) tag and purified to homogeneity. The tag was subsequently cleaved and the protein was crystallized using PEG 1000 or PEG 4000 as a precipitant. Large crystals were obtained of the native and the selenomethionine-labelled protein using sitting drops of 100-300 nl. Crystals belong to space group P6(2)22 or P6(4)22, with unit-cell parameters a = b = 68.1, c = 132.4 A. Diffraction data were collected to a maximum acceptable resolution of 2.95 and 3.20 A for the SeMet-labelled and native protein, respectively.
Efficient processing of phased array radar in sense and avoid application using heterogeneous computing (2016)

This paper describes a tightly integrated phased-array radar platform for a UAV-based sense and avoid application. The system leverages heterogeneous computing on a Zynq 7000 SoC processor to efficiently process the large streams of radar data required to guide a small Unmanned Air Vehicle (UAV) away from obstacles and intruding air vehicles. The system is mounted on a small UAV which requires stringent size, weight, and power constraints, and thus data processing must be done efficiently. The system is implemented on the commercial MicroZed development board. Low-level radar data-stream processing is performed in the FPGA fabric on the Zynq, which accelerates processing and improves energy efficiency. The Zynq ARM CPUs are used to perform higher-level radar processing and avoidance algorithms. The final proof of concept system is 2.25 × 4 × 1.5 in <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sup> weighing only 120 g (0.26 lbs) and consumes 8 watts of power. As an example, the improvements demonstrated by executing the FFT algorithm in hardware will be highlighted where hardware FFT processing provides a 17× improvement in processing time and a 49× improvement in energy efficiency over a CPU only implementation on the same SoC.
