Rhombohedral Prussian White as Cathode for Rechargeable Sodium-Ion Batteries (2015)

A novel air-stable sodium iron hexacyanoferrate (R-Na1.92Fe[Fe(CN)6]) with rhombohedral structure is demonstrated to be a scalable, low-cost cathode material for sodium-ion batteries exhibiting high capacity, long cycle life, and good rate capability. The cycling mechanism of the iron redox is clarified and understood through synchrotron-based soft X-ray absorption spectroscopy, which also reveals the correlation between the physical properties and the cell performance of this novel material. More importantly, successful preparation of a dehydrated iron hexacyanoferrate with high sodium-ion concentration enables the fabrication of a discharged sodium-ion battery with a non-sodium metal anode, and the manufacturing feasibility of low cost sodium-ion batteries with existing lithium-ion battery infrastructures has been tested.
Experimental measurements and multiphase flow models in solid SiC foam beds (2008)

Abstract Solid foam matrices have been recently introduced and present a highly permeable porous structure with a high porosity (0.60–0.95), which enables a considerably reduction of the pressure drops along the catalyst bed even with a high specific surface area. It appears today that despite the hydrodynamics of trickle‐bed reactors operating with conventional packings (spheres, extrudates, monoliths, etc.) has become largely documented in the recent literature, trickle‐bed hydrodynamic behaviour with solid foam packings, on the contrary, largely remains terra incognita. In this context, two phases flows (air–water) in solid foams under cocurrent trickle flow conditions were analyzed in a fixed‐bed at ambient conditions. From Residence Time Distribution (RTD) curves, a new set of experimental data based on the hydrodynamics parameters (pressure drop and liquid holdup) of solid foams are presented. A model based on a cubic lattice approach developed in previous work is used to calculate the equivalent diameter for solid foam packings. Finally, through the modified Eötvös number and the relative permeability concept, the two‐phase pressure drop and liquid holdup are well estimated. These news results are important parameters for the design of new process in trickle flow conditions with solid foam packing. © 2008 American Institute of Chemical Engineers AIChE J, 2008
Live migration of an entire network (and its hosts) (2012)

Live virtual machine (VM) migration can move applications from one location to another without a disruption in service. However, applications often consist of multiple VMs and rely on the state of the underlying network for basic reachability, access control, and QoS functionality. Rather than migrating an individual VM, we show how to migrate an ensemble---the VMs, the network, and the management system---to a different set of physical resources. Our LIME (LIve Migration of Ensembles) design leverages recent advances in Software Defined Networking (SDN) for a clear separation between the controller and the data-plane state in the switches. Transparent to the application running on the controller, LIME clones the data-plane state to a new set of switches, and then incrementally migrates the traffic sources (e.g., the VMs). During this transition, both networks deliver traffic and LIME maintains synchronized state. Experiments with our initial prototype, built on the Floodlight OpenFlow controller, suggest that network migration does not have to be a disruptive, middle-of-the-night maintenance event, but can become an integral network management mechanism completely transparent to applications.

Manipulating Layered P2@P3 Integrated Spinel Structure Evolution for High‐Performance Sodium‐Ion Batteries (2020)

Structural evolution of the cathode during cycling plays a vital role in the electrochemical performance of sodium-ion batteries. A strategy based on engineering the crystal structure coupled with chemical substitution led to the design of the layered P2@P3 integrated spinel oxide cathode Na<sub>0.5</sub> Ni<sub>0.1</sub> Co<sub>0.15</sub> Mn<sub>0.65</sub> Mg<sub>0.1</sub> O<sub>2</sub> , which shows excellent sodium-ion half/full battery performance. Combined analyses involving scanning transmission electron microscopy with atomic resolution as well as in situ synchrotron-based X-ray absorption spectra and in situ synchrotron-based X-ray diffraction patterns led to visualization of the inherent layered P2@P3 integrated spinel structure, charge compensation mechanism, structural evolution, and phase transition. This study provides an in-depth understanding of the structure-performance relationship in this structure and opens up a novel field based on manipulating structural evolution for the design of high-performance battery cathodes.
An experimental wind-tunnel investigation of a ram-air-spoiler roll-control device on a forward-control missile at supersonic speeds (1978)

A parametric experimental wind-tunnel investigation was made at supersonic Mach numbers to provide design data on a ram-air-spoiler roll-control device that is to be used on forward-control cruciform missile configurations. The results indicate that the ram-air-spoiler tail fin is an effective roll-control device and that roll control is generally constant with vehicle attitude and Mach number unless direct canard and/or forebody shock impingement occurs. The addition of the ram-air-spoiler tail fins resulted in only small changes in aerodynamic-center location. For the ram-air-spoiler configuration tested, there are large axial force coefficient effects associated with the increased fin thickness and ram-air momentum loss.
Expression of CD154 by a Simian Immunodeficiency Virus Vector Induces Only Transitory Changes in Rhesus Macaques (2005)

Human immunodeficiency virus infection is characterized by dysregulation of antigen-presenting cell function and defects in cell-mediated immunity. Recent evidence suggests that impaired ability of CD4+ T cells to upregulate the costimulatory molecule CD154 is at the core of this dysregulation. To test the hypothesis that increased expression of CD154 on infected CD4+ T cells could modulate immune function, we constructed a replication-competent simian immunodeficiency virus (SIV) vector that expressed CD154. We found that this recombinant vector directed the expression of CD154 on the surface of infected CD4+ T cells and that expression of CD154 resulted in activation of B cells present in the same cultures. Experimental infection of rhesus macaques resulted in very low viral loads for the CD154-expressing virus and the control virus, indicating that expression of CD154 did not result in increased viral replication. Analyses of the anti-SIV immune responses and the phenotype of lymphocytes in blood and lymphoid tissues showed changes that occurred during the acute phase of infection only in animals infected with the CD154-expressing SIV, but that became indistinguishable from those seen in animals infected with the control virus at later time points. We conclude that the level of expression of CD154 in itself is not responsible for affecting the immune response to an attenuated virus. Considering that the CD154-expressing SIV vector and the virus control did not carry an active nef gene, our results suggest that, in CD4+ T cells infected with wild-type virus, Nef is the viral factor that interferes with the immune mechanisms that regulate expression of CD154.
Regulation of plasma HDL cholesterol and subfraction distribution by genetic and environmental factors. Associations between the TaqI B RFLP in the CETP gene and smoking and obesity. (1994)

This study investigated in a healthy population (n = 220) the association of the TaqI B restriction fragment length polymorphism (RFLP) in the cholesteryl ester transfer protein (CETP) gene with plasma high-density lipoprotein (HDL) cholesterol concentration and subfraction distribution. A raised HDL cholesterol level was found in B2B2 homozygotes (B2 cutting site absent) and was associated specifically with a 45% increase in HDL2 compared with B1B1 homozygotes (B1B1, 77 +/- 39 mg/100 mL, mean +/- SD; B2B2, 112 +/- 59 mg/100 mL; P < 0.01). Total plasma, very-low-density lipoprotein, and HDL triglyceride levels did not differ among the genotype groups, nor did plasma apolipoprotein AI levels (B1B1, 1.45 +/- 0.35 mg/mL, mean +/- SD; B2B2, 1.56 +/- 0.33 mg/mL). Thus, the genetic variation appeared to be independent of metabolic factors that are known to regulate HDL levels. Plasma CETP exchange activity was unlikely to be the cause of the association, since it did not differ between genotype groups and was not correlated with HDL2 concentration. Multivariate analysis demonstrated that the TaqI B polymorphism had an effect on HDL cholesterol and HDL2 that was independent of age, sex, body mass index, oral contraceptive use, exercise, alcohol consumption, and plasma triglycerides. In smokers, the presence of the B2B2 genotype did not result in increased HDL cholesterol or HDL2, whereas in obese subjects, the difference between B1B1 and B2B2 individuals was diminished. We conclude that the TaqI B RFLP is associated with a quantitatively significant effect on plasma HDL2 levels that is independent of plasma triglycerides and interacts with lifestyle factors.
Oxamniquine treatment for schistosomal polyposis: a 1-2 year follow-up study. (1986)

A follow-up was carried out into the study of schistosomal colonic polyposis reported in the last article. Eighteen patients with schistosomal colonic polyposis were treated with oxamniquine and their progress was evaluated for 2-3 weeks after treatment, at 3 months and at 12-24 months. Sigmoidoscopy to examine mucosa on the polyps and barium enemata to determine the size and number of polyps showed variable success, but treatment with oxamniquine produced no untoward side effects.

Model Development and Use of ACE Inhibitors for Preclinical Mitigation of Radiation-Induced Injury to Multiple Organs (2014)

The NIH/NIAID initiated a countermeasure program to develop mitigators for radiation-induced injuries from a radiological attack or nuclear accident. We have previously characterized and demonstrated mitigation of single organ injuries, such as radiation pneumonitis, pulmonary fibrosis or nephropathy by angiotensin converting enzyme (ACE) inhibitors. Our current work extends this research to examine the potential for mitigating multiple organ dysfunctions occurring in the same irradiated rats. Using total body irradiation (TBI) followed by bone marrow transplant, we tested four doses of X radiation (11, 11.25, 11.5 and 12 Gy) to develop lethal late effects. We identified three of these doses (11, 11.25 and 11.5 Gy TBI) that were lethal to all irradiated rats by 160 days to test mitigation by ACE inhibitors of injury to the lungs and kidneys. In this study we tested three ACE inhibitors at doses: captopril (88 and 176 mg/m2/day), enalapril (18, 24 and 36 mg/m2/day) and fosinopril (60 mg/m2/day) for mitigation. Our primary end point was survival or criteria for euthanization of morbid animals. Secondary end points included breathing intervals, other assays for lung structure and function and blood urea nitrogen (BUN) to assess renal damage. We found that captopril at 176 mg/m2/day increased survival after 11 or 11.5 Gy TBI. Enalapril at 18–36 mg/m2/day improved survival at all three doses (TBI). Fosinopril at 60 mg/m2/day enhanced survival at a dose of 11 Gy, although no improvement was observed for pneumonitis. These results demonstrate the use of a single countermeasure to mitigate the lethal late effects in the same animal after TBI.

Highly efficient and perfectly vertical chip-to-fiber dual-layer grating coupler (2015)

A novel high-efficiency silicon-chip-to-fiber grating coupler is investigated here. By introducing a dual layer grating structure with an inter-layer lateral shift to mimic 45° tilted mirror behavior, perfectly vertical coupling is successfully demonstrated. Our numerical results show that a peak silicon-chip-to-fiber coupling efficiency about 70% is possible near 1550 nm. Meanwhile, for the entire telecom C-band, i.e. wavelengths from 1530 nm to 1565 nm, the coupling efficiency is > 50% and the back reflection is less than < 1%. Our proposed high-performance silicon perfectly vertical coupling structure is suitable for interfacing with multi-core fiber platform, which may play an important role in the future CMOS photonic integration technology.
Efficient bit-plane implementation for VC1 video decoder for multi-core architecture (2013)

VC1 is popular video standard used across many applications ranging from blu-rays disc, internet streaming, broadcast etc. The complexity of VC1 video standard requires typically hardware solution running at macro-block level. Bitplane algorithm is special processing that runs in software at frame level which results that requires higher clocking on hardware due to its inactivity during this time. This paper proposes efficient bit-plane decoding of VC1 in software by using multi-core RISC processors. The proposal uses the pipeline across multiple cores to improve overall software speed. The proposed solution is implemented on TI's Video engine (IVAHD) in multimedia chips (OMAP & DM series). The proposed solution is up-to 30% faster using two RISC processors and enables 1080p performance in 266 MHz of video hardware engine (IVAHD).
Therapeutic Hypothermia after Out-of-Hospital Cardiac Arrest in Children (2015)

Optical-fiber Fabry–Perot embedded sensor (1989)

A reflectively monitored optical-fiber Fabry-Perot interferometer was embedded in a graphite-epoxy composite material. Its performance as a temperature sensor was demonstrated from 20 to 200 degrees C. The change in relative phase shift with temperature, Deltaø/øDeltaT, was measured to be 8.0 x 10(-6)/ degrees C for this embedded sensor. This value is 4% lower than for one employing a similar fiber in an air ambient. A thermal expansion coefficient for the composite material in the direction of the fiber axis is estimated from these data to be 2.1 x 10(-7)/ degrees C.

Temporal integration and multiple looks (1991)

The decrease in detection and discrimination thresholds with increases in signal duration has often been taken to indicate that a process of relatively long-term temporal integration occurs in hearing. Two experiments are reported that suggest that no such process occurs. The first experiment is similar to the two-pulse experiment reported by Zwislocki [J. Zwislocki, J. Acoust. Soc. Am. 32, 1046-1059 (1960)] in which the threshold in quiet for a pair of brief pulses is measured as a function of the temporal separation between them. Our data indicate that power integration occurs only for separations less than approximately 5 ms. For separations larger than 5-10 ms, thresholds do not change with separation and the pulses appear to be processed independently. In the second experiment, brief 1-kHz tone pulses separated by 100 ms are presented during gaps in a wideband noise. The threshold for a pair of pulses is lower than that for either pulse presented alone, indicating that some type of "integration" occurs. However, the threshold for the pulse pair is not affected by changes in the level of the noise during the interval between the pulses. These data are inconsistent with the classical view of temporal integration that involves long-term integration. They are consistent with the notion that the input is sampled at a fairly high rate and that these samples or "looks" are stored in memory and can be accessed and processed selectively. This multiple-look model can account for the data from the present experiment and also can account for the data on temporal integration for tones and noise.(ABSTRACT TRUNCATED AT 250 WORDS)
Can we still avoid automatic face detection? (2016)

After decades of study, automatic face detection and recognition systems are now accurate and widespread. Naturally, this means users who wish to avoid automatic recognition are becoming less able to do so. Where do we stand in this cat-and-mouse race? We currently live in a society where everyone carries a camera in their pocket. Many people willfully upload most or all of the pictures they take to social networks which invest heavily in automatic face recognition systems. In this setting, is it still possible for privacy-conscientious users to avoid automatic face detection and recognition? If so, how? Must evasion techniques be obvious to be effective, or are there still simple measures that users can use to protect themselves? In this work, we find ways to evade face detection on Facebook, a representative example of a popular social network that uses automatic face detection to enhance their service. We challenge widely-held beliefs about evading face detection: do our old techniques such as blurring the face region or wearing "privacy glasses" still work? We show that in general, state-of-the-art detectors can often find faces even if the subject wears occluding clothing or even if the uploader damages the photo to prevent faces from being detected.
Three levels of G‐band differentiation (1980)

G-band "fusions" in the more contracted chromosomes, and G-band "splittings" in the longer chromosomes, have been cited directly or by implication to be natural cyclical states of human chromosomes. This report presents three levels of G-band differentiation producted by a single techinque, and compares them with three corresponding levels of R-band differentiation reported by others. It argues for the possibility of artifactural band "fusion" mechanisms in the more contracted chromosomes.

Fusing laser and image data for 3D perceived space representations (2002)

In this paper a fusion technique is presented for 3-D representation of space. The technique is based on a fusion process which involves laser range data and segmented image data with human expertise related with the surrounding environment. In particular, the range data may contain noise due to reflections on sloped surfaces or long distance open corridors, thus the proposed fusion approach removes the noise by using human expertise from 3-D environments. This method could be utilized either by an autonomous robot in an unknown environment, or by an inspection machine in a complex manufacturing environment, or by a visual navigation device used by blind people. Additional applications for this technique are the ability to correct measurement deficiencies in a laser-scan and to provide a true color and 3-D perceived shape representation for a given object in a modeling environment.
