A Membrane‐Free Redox Flow Battery with Two Immiscible Redox Electrolytes (2017)

Abstract Flexible and scalable energy storage solutions are necessary for mitigating fluctuations of renewable energy sources. The main advantage of redox flow batteries is their ability to decouple power and energy. However, they present some limitations including poor performance, short‐lifetimes, and expensive ion‐selective membranes as well as high price, toxicity, and scarcity of vanadium compounds. We report a membrane‐free battery that relies on the immiscibility of redox electrolytes and where vanadium is replaced by organic molecules. We show that the biphasic system formed by one acidic solution and one ionic liquid, both containing quinoyl species, behaves as a reversible battery without any membrane. This proof‐of‐concept of a membrane‐free battery has an open circuit voltage of 1.4 V with a high theoretical energy density of 22.5 Wh L −1 , and is able to deliver 90 % of its theoretical capacity while showing excellent long‐term performance (coulombic efficiency of 100 % and energy efficiency of 70 %).
Modulation of Pt → Ln Energy Transfer in PtLn<sub>2</sub> (Ln = Nd, Er, Yb) Complexes with 2,2′-Bipyridyl/2,2′:6′2′′-Terpyridyl Ethynyl Ligands (2008)

Reaction of (CH3)3SiC≡Cbpy (bpy = 2,2′-bipyridyl), (CH3)3SiC≡CC6H4tpy (tpy = 2,2′:6′2′′-terpyridyl), or (CH3)3SiC≡CC6H4C≡Cbpy with Pt(But2bpy)Cl2 in the presence of KF and CuI gave Pt(But2bpy)(C≡Cbpy)2 (1), Pt(But2bpy)(C≡CC6H4tpy)2 (5), or Pt(But2bpy)(C≡CC6H4C≡Cbpy)2 (9), respectively. Incorporating Ln(hfac)3 (Ln = Nd, Er, Yb; hfac = hexafluoroacetylacetonate) units with 1, 5, and 9 through 2,2′-bipyridyl/2,2′:6′2′′-terpyridyl chelation induces isolation of a series of PtLn2 heterotrinuclear complexes. Upon excitation of the PtLn2 complexes at 350 nm ≤ λex ≤ 500 nm, near-infrared (NIR) luminescence from lanthanide ions is indeed “lighting up” through effective Pt → Ln energy transfer from 3[d(Pt) → π*(But2bpy)] metal-to-ligand charge transfer transition excited-state of the Pt(But2bpy)bis(acetylide) antenna chromophore. By successive insertion of phenylene or ethynyl between acetylide and 2,2′-bipyridyl/2,2′:6′,2′′-terpyridyl in the bridging ligands, the rate and efficiency of Pt → Ln energy transfer are tunable. In contrast with quite effective Pt → Ln energy transfer in Pt−C≡Cbpy−Ln (Pt···Ln = 8.6 Å) and Pt−C≡CC6H4tpy−Ln (Pt···Ln = 14.1 Å) arrays, the long-range energy transfer across Pt−C≡CC6H4C≡Cbpy−Ln (Pt···Ln = 14.9 Å) array becomes less efficient.
Schlieren-Cinematographic and Holographic Diagnostic of a Laser-Produced Plasma in Xenon (1972)

We have studied extensively a gas breakdown in xenon produced by a giant pulse ruby laser with a power <100 MW. Detailed information concerning the structure of the laser plasma formation and of the following expansion has been obtained by different optical methods, including schlieren techniques (single frames and ultra high speed cinematography) and holography. The high quality of the holographic pictures was achieved by the use of a monomode laser. With this we were able to visualize the plasma history and to determine the velocities of the boundary layer and of the blast wave with utmost accuracy. Investigations of the electron density and electron temperature showed that a relaxation time of about 10 nsec is necessary to establish local thermodynamic equilibrium states. After this relaxation time it is then possible to carry out thermodynamic calculations, applying the shock-wave theory, to relate the optically measured expansion velocity with the plasma parameters involved. The mean specific internal energy epsilon , for instance, attained values in excess of 10(12) erg/g which decayed rapidly during the first 100 nsec to about 5. 10(10) erg/g. By comparing the results to theoretical calculations of we obtained a first estimate of the temperature, taking into consideration the partial densities n(j) as well as the partition functions Z(j)((i)) of the xenon atoms, the single-charged ions, and the double-charged ones. Furthermore, a two-step iteration computer program was used to give more detailed and more accurate results on the variations of the pressure, temperature, partial densities, and enthalpy as a function of time.

[DL] A Survey of FPGA-based Neural Network Inference Accelerators (2019)

Recent research on neural networks has shown a significant advantage in machine learning over traditional algorithms based on handcrafted features and models. Neural networks are now widely adopted in regions like image, speech, and video recognition. But the high computation and storage complexity of neural network inference poses great difficulty on its application. It is difficult for CPU platforms to offer enough computation capacity. GPU platforms are the first choice for neural network processes because of its high computation capacity and easy-to-use development frameworks. However, FPGA-based neural network inference accelerator is becoming a research topic. With specifically designed hardware, FPGA is the next possible solution to surpass GPU in speed and energy efficiency. Various FPGA-based accelerator designs have been proposed with software and hardware optimization techniques to achieve high speed and energy efficiency. In this article, we give an overview of previous work on neural network inference accelerators based on FPGA and summarize the main techniques used. An investigation from software to hardware, from circuit level to system level is carried out to complete analysis of FPGA-based neural network inference accelerator design and serves as a guide to future work.
Solving SAT-encoded Formal Verification Problems on SoC Based on a WSAT Algorithm with a New Heuristic for Hardware Acceleration (2013)

In this paper, we describe a heuristic in a Walk SAT (WSAT) algorithm for solving SAT-encoded formal verification problems efficiently on hardware, and its expected performance on system on chip (SoC). In WSAT algorithms, an assignment of binary values to the variables which satisfy all clauses is searched by repeatedly choosing a variable in an unsatisfied clause using a heuristic, and flipping its value. In the SAT-encoded formal verification problems, logic gates and their functional dependencies can be reconstructed from their propositional conjunctive normal form. In our heuristic, first, the output signals of logic gates are flipped preferentially to propagate the changes in the upper stream to their down-stream efficiently. Secondly, a search direction control mechanism is introduced to change the data propagation direction automatically: from the upper to the lower or from the lower to the upper. We show how our heuristic on SoC can improve the performance of WSAT algorithms.
Entrainment of mainstream flow in a trapped-vortex combustor (1997)

A laboratory-scale combustor is described. To provide good flame stabilization the combustor uses a vortex formed and trapped inside an annular cavity introduced into a centerbody that is placed in a concentric, axially flowing mainstream which is confined by a circular duct. Separately-controlled primary air and gaseous propane are directly injected unpremixed into the cavity for combustion purposes. The stability of the vortex in a driven-cavity is determined by the cavity dimensions. For a cavity that is additionally pumped by the directly-injected primary air and fuel flows, the relative momenta of the mainstream and injected cavity flows will also determine the combustion stability through the entrainment of mainstream flow into the cavity. Direct measurements of cavity entrainment are difficult to make. However, indirect assessments of enlrainment are possible from other measurements with a few plausible assumptions. Indirect estimates of entrainment are provided over wide ranges of operating conditions at atmospheric temperature and pressure for several cavity sizes.
Evolutionary Optimal Virtual Machine Placement and Demand Forecaster for Cloud Computing (2011)

Cloud computing allows the users to efficiently and dynamically provision computing resources to meet their IT needs. Most cloud providers offer two types of payment plans to the user, i.e., reservation and on-demand. The reservation plan is typically cheaper than the on-demand plan but reservation plan has to be provisioned in advance. Reserving the resources would be straightforward if the actual computing demand (e.g., job processing) is known in advance. However, in reality, the actual computing demand can be observed only at the point of actual usage. Therefore, it is difficult to reserve the correct amount of resources during the reservation to meet the computing demands of the users. In this paper, we propose an evolutionary optimal virtual machine placement (EOVMP) algorithm with a demand forecaster. First, a demand forecaster predicts the computing demand. Then, EOVMP uses this predicted demand to allocate the virtual machines using reservation and on-demand plans for job processing. The performance of the proposed schemes is evaluated by simulations and numerical studies. The evaluation result shows that the EOVMP algorithm can provide the solution close to the optimal solution of stochastic integer programming (SIP) and the prediction of the demand forecaster is of reasonable accuracy.
A Nonlinear Strategy to Control Unstable Underactuated Mechanical Systems with Underactuation > 1. Applications to Control Augmentations (2009)

The essence of the complex dynamics originated by the interaction between the pilot-&-aircraft can be captured on labs, by means of unstable-underactuated mechanical systems. Thus, the unactuated links describe the autonomous aircraft dynamics (flight control system) and the actuated the manual one (pilot). It is well-known that, in some flight conditions, the pilot-&-aircraft interaction can render the system unstable. Thus, a standard solution of designing a decoupled dynamics between the flight control system and the pilot, either becomes useless or restrict the maneuverability unnecessarily. The nonlinear and compact strategy proposed here can pave the way to a less conservative (or even safety) solution in aircraft implementation. Successful experiments on the Furuta's pendulum are reported and to the best of authors' knowledge it has the largest attraction basin experimentally tested so far.
Disruption of CCL21-Induced Chemotaxis In Vitro and In Vivo by M3, a Chemokine-Binding Protein Encoded by Murine Gammaherpesvirus 68 (2002)

Chemokine-binding proteins represent a novel class of antichemokine agents encoded by poxviruses and herpesviruses. One such protein is encoded by the M3 gene present in the murine gammaherpesvirus 68 (MHV-68) genome. The M3 gene encodes a secreted 44-kDa protein that binds with high affinity to certain murine and human chemokines and has been shown to block chemokine signaling in vitro. However, there has been no direct evidence that M3 blocks chemokine activity in vivo, nor has the nature of M3-chemokine interaction been defined. To better understand the ability of M3 to block chemokine activity in vivo, we examined its interaction with a specific subset of chemokines expressed in lymphoid tissues, areas where gammaherpesviruses characteristically establish latency. Here we show that M3 blocks in vitro chemotaxis induced by CCL19 and CCL21, chemokines expressed constitutively in secondary lymphoid tissues. Moreover, we provide evidence that chemokine M3 binding exhibits positive cooperativity. In vivo, the expression of M3 in the pancreas of transgenic mice inhibits recruitment of lymphocytes induced by transgenic expression of CCL21 in this organ. The ability of M3 to block the biological activity of chemokines may represent an important strategy used by MHV-68 to evade immune detection and favor viral replication in the infected host.
Jazz and nation in Australia: bridging the gap on the screen, 1919–1933 (2011)

When jazz arrived in Australia as live performance in 1918, it initially was \ntaken by the establishment as a threat to national identity, in particular \nas that identity had been associated with masculinist rural mythologies \ncentred on what was known as ‘the Bush’.1\n The Bush was where the nation \nwas created, through the heroic labour required for the conquest of the \nland. With its roots in nineteenth century pioneer frontier narratives, the \nvalues of the Bush were at odds with urban modernity and the lifestyles \nit fostered. The musical expression of the latter was jazz – a cacophonous \nimportation from the USA with connotations of ‘negroid’ savagery and \ndecadent effeminisation. Jazz thus functioned as the ‘Other’ in received \ndiscourses of nation. By the 1950s there was a growing synergy between \nAustralian identity and jazz, consolidated by the arrival of a new music \nof the Other in the form of rock’n’roll. But the beginnings of this rapprochement can be identified from the early thirties when changes in \nthe understanding of both jazz and nation began to bring the two into \ncloser alignment. This paper explores those early relational shifts as they were manifested cinematically. Although it is widely held that the Great \nDepression ended the first phase of Australian jazz history, nonetheless it \nwill be argued here that it was the search for solutions to the problem of \nthe Depression that help to build a ‘bridge’ between jazz and Australian \nidentity, in conjunction with a new appreciation of the meliorative possibilities of modernity, particularly as reflected in the construction of the \nSydney Harbour Bridge and the transition from silent to sound films.

Distinct distributions of five <i>N</i>‐methyl‐<scp>D</scp>‐aspartate receptor channel subunit mRNAs in the forebrain (1993)

Abstract The distributions of five NMDA receptor channel subunit mRNAs in the mouse forebrain at postnatal day 21 were semiquantitatively examined by in situ hybridization with subunit‐specific oligonucleotide probes. In contrast to ubiquitous distribution of the ζ1 subunit mRNA throughout the forebrain, distributions of four ϵ subunit mRNAs were highly variable from nucleus to nucleus. The telencephalon (except for the septum) expressed the ϵ1 and ϵ2 subunit mRNAs. Various combinations of the ϵ1, ϵ2, ϵ3, and ϵ4 subunit mRNAs were present in different nuclei of the septum, the olfactory bulb, and the thalamus. In the hypothalamus, the suprachiasmatic nucleus expressed distinct signals for the ϵ3 subunit mRNA alone, whereas other nuclei showed faint signals for the ϵ1, ϵ2, and ϵ4 subunit mRNAs. Moreover, different signal levels of the ϵ subunit mRNAs were found in various regions. The hippocampal CA1 region expressed higher signals for the ϵ1 and ϵ2 subunit mRNAs than the CA3 region and the dentate gyrus. In the cerebral cortex, signal levels of the ϵ1 subunit mRNA were higher in the laminae II/III, IV, and VI than the lamina V, whereas those of the ϵ2 subunit mRNA were highest in laminae II/III and lowest in laminae IV and V. Different signal levels between the ϵ1 and ϵ2 subunit mRNAs were also discerned in the amygdala, the caudate‐putamen, and the thalamus. The distinct anatomical distributions and differential signal levels of the ϵ subunit mRNAs strongly suggest different subunit organizations of the NMDA receptor channel in different forebrain neurons, which may result in functional diversity of the channel in vivo. © 1993 Wiley‐Liss, Inc.
Program improvement by source to source transformation (1976)

We treat a program as an object of manipulation, determine items of program constancy, and simplify the program based on the constancy. Some motivation for program manipulation is presented, along with two examples of “higher level optimization” written in an Algol-like language. A collection of program transformations and a model of the compilation process in terms of source-to-source transformations are presented. Finally a description of the application of these ideas to an existing programming language is given.

Direct neural sensory feedback and control of a prosthetic arm (2005)

Evidence indicates that user acceptance of modern artificial limbs by amputees would be significantly enhanced by a system that provides appropriate, graded, distally referred sensations of touch and joint movement, and that the functionality of limb prostheses would be improved by a more natural control mechanism. We have recently demonstrated that it is possible to implant electrodes within individual fascicles of peripheral nerve stumps in amputees, that stimulation through these electrodes can produce graded, discrete sensations of touch or movement referred to the amputee's phantom hand, and that recordings of motor neuron activity associated with attempted movements of the phantom limb through these electrodes can be used as graded control signals. We report here that this approach allows amputees to both judge and set grip force and joint position in an artificial arm, in the absence of visual input, thus providing a substrate for better integration of the artificial limb into the amputee's body image. We believe this to be the first demonstration of direct neural feedback from and direct neural control of an artificial arm in amputees.
Distinct Renal Injury in Early Atherosclerosis and Renovascular Disease (2002)

Early chronic HC+RAS imposes distinct detrimental effects on renal function and structure in vivo and in vitro, evident primarily in the tubular and glomerular compartments. Increased oxidative stress may be involved in the proinflammatory and progrowth changes observed in the stenotic HC+RAS kidney, which might potentially facilitate the clinically observed progression to end-stage renal disease.
A Study on Environmental Compliance of Indian Leather Industry & its Far-reaching Impact on Leather Exports (2012)

Indian Leather Industry is recognized as one of the most promising foreign exchange earning sectors since early 1970s. The industry was hard hit by two consecutive foreign environment bans since 1989. Along with that, few domestic environmental regulations also resulted into closure down of a number of leather tanneries during this period. However, the government intervention and the successive compliance measures adopted by the firms ultimately helped the industry to gain momentum in its export sector. This paper analyzes the far reaching impact of these environmental regulations on export sector of Indian Leather Industry. Whether this boost in leather export marks a trade-off relation between environmental quality and volume of exports is a matter of debate, which is attempted in this paper. This paper, within the limitations of data availability regarding environmental statistics, has determined a positive relation between environmental quality and volume of leather exports and justified that instead of Pollution Haven Hypothesis, Indian Leather Industry rather confirms Porterɺs Hypothesis.
Resection Angulation Osteotomy in Treatment of Post-septic Ankylosis of the Hip (2008)

We performed the procedure in 19 patients, with average age of 26 years (range, 21-32 years) and followed patients postoperatively for an average of 43 months (range 20-65 months). The osteotomy united in all patients with an average union time of 16 weeks (range 12-22 weeks).
Gene expression analysis of immunostained endothelial cells isolated from formaldehyde‐fixated paraffin embedded tumors using laser capture microdissection—A technical report (2009)

Laser capture microdissection (LCM) allows microscopic procurement of specific cell types from tissue sections that can then be used for gene expression analysis. In conventional LCM, frozen tissues stained with hematoxylin are normally used to the molecular analysis. Recent studies suggested that it is possible to carry out gene expression analysis of formaldehyde-fixated paraffin embedded (FFPE) tissues that were stained with hematoxylin. However, it is still unclear if quantitative gene expression analyses can be performed from LCM cells from FFPE tissues that were subjected to immunostaining to enhance identification of target cells. In this proof-of-principle study, we analyzed by reverse transcription-PCR (RT-PCR) and real time PCR the expression of genes in factor VIII immunostained human endothelial cells that were dissected from FFPE tissues by LCM. We observed that immunostaining should be performed at 4 degrees C to preserve the mRNA from the cells. The expression of Bcl-2 in the endothelial cells was evaluated by RT-PCR and by real time PCR. Glyceraldehyde-3-phosphate dehydrogenase and 18S were used as house keeping genes for RT-PCR and real time PCR, respectively. This report unveils a method for quantitative gene expression analysis in cells that were identified by immunostaining and retrieved by LCM from FFPE tissues. This method is ideally suited for the analysis of relatively rare cell types within a tissue, and should improve on our ability to perform differential diagnosis of pathologies as compared to conventional LCM.
Protein-DNA conjugates produced by UV irradiation and their use as probes for hybridization (1989)

Several proteins have been crosslinked to DNA by low dose uv irradiation. The principle of the method is based on an efficient and fast radiation induced reaction of amino acid residues with DNA at low pH. The method seems to be of general applicability for crosslinking proteins to DNA in a very simple one step procedure. Some of such DNA-protein conjugates have been used as probes for hybridization experiments. DNA-protein A probes were found to be most useful.
Neurons in the Rat Dentate Gyrus Granular Layer Substantially Increase During Juvenile and Adult Life (1982)

Volumetric estimates of the total number of granule cells in rats 30, 120, 200, and 365 days old increase linearly by approximately 35 to 43 percent between 1 month and 1 year. Total volume of the granular layer also grows linearly during that time. These results demonstrate a numerical increase in a neuronal population during adulthood in the mammalian brain.
An optimized Faraday cage design for electron beam current measurements (1975)

Describes a Faraday cage detector for measuring electron beam intensity for use with energies up to 1.2 MeV, with the present data taken at 100 keV. The design features a readily changeable limiting aperture and detector cup geometry, and a secondary electron suppression grid. The detection efficiency of the cage is shown to be limited only by primary backscatter through the detector solid angle of escape, which is optimized with respect to primary backscattered electrons and secondary electron escape. The geometry and stopping material of the detection cup are varied, and the results show that for maximum detection efficiency with carbon as the stopping material, the solid angle of escape must be equal to or less than 0.05 pi sr. The experimental results are consistent within the +or-2% accuracy of the detection electronics, and are not limited by the Faraday cage detection efficiency.
