Pneumatic Morphing Aspect Ratio Wing (2004)

This paper discusses the design, development and testing of a pneumatic telescopic wing that permits a change in the aspect ratio while simultaneously supporting structural wing loads. The key element of the wing consists of a pressurized telescopic spar that can undergo large-scale span wise changes while supporting wing loadings in excess of 15 lbs/ft. The wing cross-section is maintained by NACA0013 rib sections fixed at the end of each mobile element of the telescopic spar. Hollow fiberglass shells are used to preserve the span wise airfoil geometry and ensure compact storage and deployment of the telescopic wing. A fullscale telescopic wing assembly was built and tested in the Glenn L. Martin Wind Tunnel at the University of Maryland. These tests included measurements of Lift, Drag, and Lift to Drag ratio at a variety of Reynolds numbers. The telescopic wing was tested in four different configurations and experimental results were compared to finite wing theory results. Preliminary aerodynamic results are promising for the variable aspect ratio telescopic wing. It was expected that the telescopic wing at maximum deployment should incur a slightly larger drag penalty and a reduced lift to drag ratio. Thus, it may be possible to develop UAVs with variable aspect ratio wings using pneumatic telescopic spars and skin sections. This paper presents and discusses parts of the aspect ratio morphing concept, using pneumatic telescopic spars to actuate the wing and sustain aerodynamic wing loads, while being fully controlled in a timely manner.

This analysis suggests that initial response to treatment with glucocorticoids may be an important prognostic factor in patients with PCNSL.
Accurate reflectance prediction in multi-angle measurement (2008)

This study focuses on finding the best viewing angles so that accurate reflectance prediction could be achieved in multi-angle measurement of metallic and pearlescent samples. The root mean square error (RMSE) produced by the reconstruction from the first seven Principle component vectors (PCV), the cumulative contribution being 99.92 percent, were analyzed to find the best viewing angles 10°, 65°, 95°, 120°, 145°, 155° and 170° in clock wise direction from the surface for illumination angle of 45°. The error difference resulted by prediction using cubic interpolation and proposed Principle component analysis (PCA) based method were compared. The prediction by PCA based method outperforms the prediction by cubic interpolation. The method can be employed not only to metallic and pearlescent samples but to all non lambertian surfaces.
Compartmentalization by directional gene expression (2010)

The coalescence of basic biochemical reactions into compartments is a major hallmark of a living cell. Using surface-bound DNA and a transcription reaction, we investigate the conditions for boundary-free compartmentalization. The DNA self-organizes into a dense and ordered phase with coding sequences aligned at well-defined distances and orientation relative to the surface, imposing directionality on transcription. Unique to the surface in comparison to dilute homogeneous DNA solution, the reaction slows down early, is inhibited with increased DNA density, is favorable for surface-oriented promoters, and is robust against DNA condensation. We interpret these results to suggest that macromolecules (RNA polymerase and RNA), but not solutes (ions and nucleotides), are partitioned between immobilized DNA and the reservoir. Without any physical barrier, a nonequilibrium directional DNA transaction forms macromolecular gradients that define a compartment, thus offering a boundary-free approach to the assembly of a synthetic cell.
INFRARED IMAGING OF CIRCUMSCRIBED CHOROIDAL HEMANGIOMAS (2016)

Infrared imaging delineates intratumoral vessels in choroidal tumors appearing as dark beaded loops and tufts. Vascular loops on IR imaging showed a high diagnostic sensitivity for CCH. The absence of these loops on IR can help rule out the diagnosis of CCH. Peritumoral vascular expansion on indocyanine green is an additional diagnostic tool that is helpful in the diagnosis of CCH.
Application of a sunburst aperture to diffraction suppression* (1974)

A closed-form solution to a two-dimensional Fourier transform of a toothed wheel or sunburst is presented. The solution was obtained by decomposing the sunburst aperture into triangles and applying the superposition principle to sum the Fourier transforms of the subapertures. This technique is applicable to analyzing and designing other complicated apertures. Computer plots are presented that show the spatial transforms along the radial and angular directions. For small radial distances, the transform resembles that of a circle, whereas for large radial distances, it has preferred angular directions that are perpendicular to every edge of the aperture. The power spectrum or the magnitude squared of the transform is a close approximation of the Fraunhofer diffraction pattern of the aperture. Contour shaping of this type is an effective means of apodizing diffraction of unwanted sources of small angular subtense but becomes ineffective when the angular subtense of the unwanted sources are large.
Buffer analysis for a data sharing environment with skewed data access (1994)

Examines the effect of skewed database access on the transaction response time in a multisystem data sharing environment, where each computing node has access to shared data on disks, and has a local buffer of recently accessed granules. Skewness in data access can increase data contention since most accesses go to few data items. For the same reason, it can also increase the buffer hit probability. We quantify the resultant effect on the transaction response time, which depends not only on the various system parameters but also on the concurrency control (CC) protocol. Furthermore, the CC protocol can give rise to rerun transactions that have different buffer hit probabilities. In a multisystem environment, when a data block gets updated by a system, any copies of that block in other systems' local buffers are invalidated. Combining these effects, we find that higher skew does not necessarily lead to worse performance, and that with skewed access, optimistic CC is more robust than pessimistic CC. Examining the buffer hit probability as a function of the buffer size, we find that the effectiveness of additional buffer allocation can be broken down into multiple regions that depend on the access frequency distribution.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Impact of Excess Li on the Structural and Electrochemical Properties of Li1+x(NizCo1-2zMnz)1-xO2 Materials for Lithium-Ion Batteries (2010)

LiNizCo1−2zMnzO2 materials have been investigated as promising positive electrode materials for lithium-ion secondary batteries, in which cobalt ions are simultaneously substituted with nickel and manganese ions while preserving the α-NaFeO2 structure. The materials can be regarded as solid solutions of LiNiO2, LiCoO2, and LiMnO2, in which the transition metals are trivalent in all three materials, whereas the transition metals found in LiNizCo1−2zMnzO2 materials are Ni2+, Co3+, and Mn4+. The electrochemical lithium deintercalation-intercalation processes of these materials are mainly accompanied by the Ni2+/4+ and Co3+/4+ redox reactions, whereas Mn4+ ions do not participate in the electrochemical redox reaction. Recently, Li+ substitution for transition metals in Li1+x(NizCo1−2zMnz)1−xO2, so called overlithiation, has been introduced to improve their structural integrity and electrochemical performances.In this paper, we introduce the overlithiation effects on the structural and electrochemical properties of the Li1+x(NizCo1−2zMnz)1−xO2 materials having diffrrent x- and z-values in the ranges from x=0.00 to x=0.17 and z=0.00 to z=0.50.
Microporous carbon–nitrogen fibers from keratin fibers by pyrolysis (2010)

Abstract A two‐step pyrolysis method was developed for poultry keratin fibers to convert them into high temperature resistant and adsorbent fibers while retaining their original physical appearance and affine dimensions. Nearly all accessible pores in the microporous pyrolyzed chicken feather fibers (PCFF) have a diameter less than 1 nm and could be used in applications, such as adsorption, hydrogen storage, and separation of small gas molecules. An intermolecular crosslinking mechanism in the first step of pyrolysis at 215°C for 24 h provided an intact fibrous structure with no subsequent melting. The second step of the pyrolysis at 400–450°C for 1 h resulted in a microporous material with a narrower pore size distribution than commercial activated carbons. Surface and bulk characterization techniques including XPS, total carbon–nitrogen, and FTIR were utilized to examine property changes occurring during the two pyrolysis steps. A partially cyclic carbon–nitrogen framework (carbon/nitrogen ratio = 2.38) supported by double and triple bonds, and oxygen functionalities is the suggested structural model for the PCFF. © 2010 Wiley Periodicals, Inc.

Determination of dipole coupling constants using heteronuclear multiple quantum NMR (1982)

The problem of extracting dipole couplings from a system of N spins I = 1/2 and one spin S by NMR techniques is analyzed. The resolution attainable using a variety of single quantum methods is reviewed. The theory of heteronuclear multiple quantum (HMQ) NMR is developed, with particular emphasis being placed on the superior resolution available in HMQ spectra. Several novel pulse sequences are introduced, including a two-step method for the excitation of HMQ coherence. Experiments on partially oriented [1−13C] benzene demonstrate the excitation of the necessary HMQ coherence and illustrate the calculation of relative line intensities. Spectra of high order HMQ coherence under several different effective Hamiltonians achievable by multiple pulse sequences are discussed. A new effective Hamiltonian, scalar heteronuclear recoupled interactions by multiple pulse (SHRIMP), achieved by the simultaneous irradiation of both spin species with the same multiple pulse sequence, is introduced. Experiments are described which allow heteronuclear couplings to be correlated with an S-spin spreading parameter in spectra free of inhomogeneous broadening.
Thermoshrinking behavior of poly(vinylcaprolactam) gels in aqueous solution (1996)

Abstract The swelling of newly synthesized slightly crosslinked gels of polyvinylcaprolactam (PVCa) was studied as a function of temperature. In water, PVCa gels undergo a sharp volume transition from a swollen to a collapsed state on heating. In water/alcohol mixtures, the gel first shrinks and then expands as the temperature is raised. The swelling behavior of the thermosensitive PVCa gel in surfactant solution depends on kind and concentration of the surfactant. Normally, an additional swelling of the gel is observed in the presence of ionic surfactants. Addition of the surfactant raises the collapse transition temperature of the gel. Absorption of the surfactant by the PVCa gel as a function of temperature and surfactant concentration is analysed in detail.
On the Goldie Dimension of Hereditary Rings and Modules (2005)

We find a bound for the Goldie dimension of hereditary modules in terms of the cardinality of the generator sets of its quasi-injective hull. Several consequences are deduced. In particular, it is shown that every right hereditary module with countably generated quasi-injective hull is noetherian. Or that every right hereditary ring with finitely generated injective hull is artinian, thus answering a long standing open question posed by Dung, Gomez Pardo and Wisbauer.
Functional analysis of novel Rab GTPases identified in the proteome of purified<i>L</i><i>egionella</i>-containing vacuoles from macrophages (2013)

The opportunistic pathogen Legionella pneumophila employs the Icm/Dot type IV secretion system and ∼300 different effector proteins to replicate in macrophages and amoebae in a distinct 'Legionella-containing vacuole' (LCV). LCVs from infected RAW 264.7 macrophages were enriched by immuno-affinity separation and density gradient centrifugation, using an antibody against the L. pneumophila effector SidC, which specifically binds to the phosphoinositide PtdIns(4)P on the pathogen vacuole membrane. The proteome of purified LCVs was determined by mass spectro-metry (data are available via ProteomeXchange with identifier PXD000647). The proteomics analysis revealed more than 1150 host proteins, including 13 small GTPases of the Rab family. Using fluorescence microscopy, 6 novel Rab proteins were confirmed to localize on pathogen vacuoles harbouring wild-type but not ΔicmT mutant L. pneumophila. Individual depletion of 20 GTPases by RNA interference indicated that endocytic GTPases (Rab5a, Rab14 and Rab21) restrict intracellular growth of L. pneumophila, whereas secretory GTPases (Rab8a, Rab10 and Rab32) implicated in Golgi-endosome trafficking promote bacterial replication. Upon silencing of Rab21 or Rab32, fewer LCVs stained positive for Rab4 or Rab9, implicated in secretory or retrograde trafficking respectively. Moreover, depletion of Rab8a, Rab14 or Rab21 significantly decreased the number of SidC-positive LCVs, suggesting that PtdIns(4)P is reduced under these conditions. L. pneumophila proteins identified in purified LCVs included proteins putatively implicated in phosphorus metabolism and as many as 60 Icm/Dot-translocated effectors, which are likely required early during infection. Taken together, the phagocyte and Legionella proteomes of purified LCVs lay the foundation for further hypothesis-driven investigations of the complex process of pathogen vacuole formation.
Atomic Structures of Oxygen-associated Defects in Sintered Aluminum Nitride Ceramics (1999)

: Convergent-beam electron diffraction and Z-contrast imaging are used to study oxygen-associated defects, flat inversion domain boundaries, dislocations, and interfaces in sintered AlN ceramics. The structures of these defects are directly derived from atomic-resolution Z-contrast images. The flat inversion domain boundaries contain a single Al-O octahedral layer and have a stacking sequence of.bAaB-bAc-CaAc., where -cAb- indicates the single octahedral layer. The expansion at the flat inversion domain boundaries is measured to be 0.06 (+/-0.02) nm. The interfaces between 2H- and polytypoid-AlN are found to be also inversion domain boundaries but their stacking sequence differs from that of the flat inversion domain boundaries.
Structural-Aerodynamic Coupling For Wells Turbine Blades (1999)

The coupling of structural and aerodynamic forces for a lightweight, axial flow Wells air turbine is investigated through a NACA0012 blade: chord length 0.3 m; Aspect Ratio 2. Design loadings and aeroelastic behaviour were investigated by building the geometry and finite element mesh using MSC/PATRAN and then solving in the MSC/NASTRAN finite element package. Subsonic Doublet Lattice theory was used to model the aerodynamics while coupling to the structural model was achieved through Surface Splining. The p-k method was utilised for the aeroelastic analysis where damping and frequency are calculated with respect to velocity, delivering the flutter and divergence speeds. The analysis assumes that the relative air velocity remains constant with radius while the aerodynamic cases consider the mid-span position. Results include: static analysis to compute the displacements and stresses under centrifugal and static aerodynamic loading; modal analysis to compute the various modes of vibration; aeroelastic analysis to compute the divergence and flutter speeds. Material stresses were found to be at an appropriate level for this stage of the design, while the operational speed was well below that of aeroelastic failure.

FK–506 Monotherapie mit früher Steroidreduktion nach orthotoper Lebertransplantation – Erste Ergebnisse einer prospektiv randomisierten Placebo-kontrollierten Doppelblindstudie (2005)

Einleitung: In der Anfangsphase der Transplantationsmedizin waren die immunsuppressiven Wirkungen von Steroiden der Garant für erfolgreiche Organtransplantationen. Aufgrund der Verfügbarkeit von potenten Immunsuppressiva sind Steroide in den vergangen Jahren zunehmend in den Hintergrund gerückt. Unerwünschte Arzneimittelwirkungen der Steroide sollen durch frühzeitige Reduktion vermindert werden. Material und Methoden: Nach Aufklärung und schriftlicher Zustimmung zum Studienprotokoll wurden alle Patienten vor OLT randomisiert. FK 506 wurde als Immunsuppressivum verwendet (Zielspiegel 10 bis 15 ng/ml während der ersten 6 postoperativen Wochen, danach 5 bis 10 ng/ml). Während der ersten 14 Tage erhielten beide Gruppen Methylprednisolon (intraoperativ 1g, Reduktion bis zum 14. post OP Tag auf 12mg). Nach dem 14. Tag wurde mit doppelt verblindetem Studienmedikament weiterbehandelt: Die Studiengruppe (SG) erhielt Placebo, die Kontrollgruppe (KG) Methylprednisolon (12mg/d bis einschließlich 8 Wochen nach OLT, danach 8mg/d bis 6 Monate nach OLT). Nach sechs Monaten wurde das Studienmedikament beendet, der Follow-up wurde 1 Jahr nach OLT beendet. Studienendpunkte waren das Auftreten von akuten und chronischen Abstoßungen, Patienten und Transplantatüberleben sowie das Auftreten von Diabetes mellitus, Osteoporose, Fettstoffwechselstörungen, arterieller Hypertonie sowie Infektionen. Ergebnisse: Von 02/2000 bis 07/2004 wurden 108 Patienten nach OLT in die Studie eingeschlossen. 83 Patienten haben die Nachbeobachtung aktuelle beendet. Davon waren 41 Patienten in die SG und 42 in die KG randomisiert. Insgesamt traten 51 akute Rejektionen bei 42 Patienten auf. Davon traten 22 Rejektionen in der SG und 19 Rejektionen in der KG auf (p=0,513). In der SG traten zwei chronische Abstoßungen auf während in der KG keine chronischen Abstoßungen auftraten (p=0,241). 4 Patienten sind während der Studie verstorben: 2 in der KG (HCC-Rezidiv sowie HCV-Rezidiv) sowie 2 in der SG (PNF und Sepsis). Das Ein-Jahres-Patienten Überleben lag in beiden Gruppen bei 95%. Die Daten bezüglich Diabetes mellitus, Fettstoffwechselstörung, Osteoporose, Hypertension und Infektion sind derzeit noch verblindet und werden zum Kongress präsentiert. Zusammenfassung: Eine frühe FK 506 Monotherapie nach OKT ist effektiv und sicher. Diese Studie zeigte keinen Unterschied in der Häufigkeit von Rejektionen unabhängig von der Verwendung von Steroiden.
Search for the decays Bd0 → γγ and Bs0 → γγ (1995)

A search for the decays Bd,s0 → γγ in 2.95 million hadronic Z decays has been performed using the L3 detector at LEP. No candidates are found in the signal region and upper limits have been set on the branching ratios: Br(Bd0→γ)<3.9×10−5 and Br(Bs0 → γγ) < 14.8 × 10−5 at 90% CL. These are the first limits set on these exclusive rare decays.
A CMOS VLSI delay oriented waveform converter dedicated to the synthesizer of an UMTS transceiver (2002)

In this paper we present a waveform converter implemented on a 0.25 /spl mu/m CMOS technology using a dedicated design methodology (delay oriented design). The circuit converts a square wave signal in both in-phase and quadrature-phase sinusoidal differential outputs. It also multiplies the frequency by seven. The output frequency range of this converter extends from 1.05 GHz up to 2.17 GHz. This converter is dedicated for the design of a third generation mobile phone synthesizer using a double loop architecture. For an output frequency of 2 GHz, the measured phase noise at 10 kHz offset from the carrier is -97 dBc/Hz. The circuit consumes 50 mW from a 2.5 V supply.

Incrimination of anaerobic bacteria in the induction of experimental colitis (1997)

Commensal bacteria may participate in the pathogenesis of bowel inflammation. We studied the role of bacteria from the rat colonic flora on transmural inflammation induced by 2,4,6-trinitrobenzenesulfonic acid (TNBS). First, bacterial translocation to the colonic wall after induction of colitis was assessed by microbiological and histological methods. Second, rats with a colonic segment excluded from fecal transit were prepared for recolonization with preselected bacteria and used to test the effects of different species on inflammation (eicosanoid release, tissue myeloperoxidase) and damage (histology). Six strains (three aerobes and three anaerobes) were identified in colonic tissue 24 h after induction of colitis. Acridine staining showed bacteria in necrotic areas of the mucosa and invading the submucosa. Rats with excluded colon and sterile culture of luminal washings showed mild inflammation and low mucosal damage in response to TNBS. Rats colonized with anaerobes showed significantly higher eicosanoid release than rats colonized with aerobes only. Moreover, submucosal-lesions were mostly observed in rats with anaerobes. Our findings suggest that colonic anaerobes play a key role in transmural inflammation.
Implementation of Web-based Operational Log System at RIBF (2018)

The operational log system is one of the electric log systems for recording and viewing the accelerator operation time and contents of an operated device. Zlog (Zope-based log system)* developed by KEK was utilized for the RIBF control system. Zope is an open-source Web server and Web application framework written in Python. Using the Web application, information on accelerator operation is designated by a character string on Web browsers. However, the displayed string character on the Web browser will be complex for accelerator operators because many parameters are changed in accelerator operation, though the Web-based system has many advantages. For smoother accelerator operation, an ergonomically designed operational log system is required. Therefore, we developed a new operational log system for RIBF control system. The new system is possible to provide operational logs with a variety of rich GUI components. As of now, the operational log system has been working for accelerator operation by monitoring approximately 3,000 points as the EPICS record without any serious problem.
