Low-complexity feedback-channel-free distributed video coding using\n Local Rank Transform (2016)

In this paper, we propose a new feedback-channel-free Distributed Video\nCoding (DVC) algorithm using Local Rank Transform (LRT). The encoder computes\nLRT by considering selected neighborhood pixels of Wyner-Ziv frame. The ranks\nfrom the modified LRT are merged, and their positions are entropy coded and\nsent to the decoder. In addition, means of each block of Wyner-Ziv frame are\nalso transmitted to assist motion estimation. Using these measurements, the\ndecoder generates side information (SI) by implementing motion estimation and\ncompensation in LRT domain. An iterative algorithm is executed on SI using LRT\nto reconstruct the Wyner-Ziv frame. Experimental results show that the coding\nefficiency of our codec is close to the efficiency of pixel domain distributed\nvideo coders based on Low-Density Parity Check and Accumulate (LDPCA) or turbo\ncodes, with less encoder complexity.\n
Requirement for hexose, unrelated to energy provision, in T-cell-mediated cytolysis at the lethal hit stage. (1978)

The requirement for D-glucose in T-cell-mediated cytolysis was studied using mouse spleen cells sensitized against alloantigens in vitro. Glucose was required for cytolysis: (a) cytolysis proceeded in a simple buffered salt solution containing Ca++ and Mg++ (low phosphate-buffered saline, LPBS) in the presence but not in the absence of added glucose; (b) 2-deoxy-D-glucose blocked cytolysis. The block by this agent was overcome by excess glucose added as late as 40 min after the inhibitor. This block was not due to inhibition of NADP reduction, since 2-deoxy-D-glucose failed to interfere with the rate of CO2 production by the pentose cycle which we found to be of significant activity in sensitized spleen cells; (c) dialyzed fetal bovine serum (DFBS) in LPBS supported cytolysis in the absence of added glucose. However, 2-deoxy-D-glucose was also inhibitory under these conditions, suggesting that carbohydrate was required here as well. Further results supported the conclusion that DFBS was not acting as a direct source of the required carbohydrate. The relationship between cytolysis, glucose requirement, and provision of energy was studied. As little as 0.1 mM D-glucose in LPBS supported cytolysis. At this glucose concentration, there was no measurable accumulation of lactate in sensitized spleen cells, but Krebs cycle activity was detectable. In 3 mM glucose or above, the range covered by standard tissue culture media, anaerobic glycolysis became a major source of energy in sensitized spleen cells. Consequently, it appears that in standard tissue culture medium, effector cells can generate sufficient energy for cytolysis either by aerobic or anaerobic metabolism. However, the addition of an energy source alone in the absence of glucose was insufficient to support cytolysis in LPBS. Pyruvate in LPBS did not support cytolysis but was shown to be a good substrate for aerobic metabolism in sensitized spleen cells. Glycogenic amino acids and glycerol also failed to support cytolysis. The stage of cytolysis at which glucose is required was investigated. Glucose was necessary for the calcium-dependent lethal hit phase, but not for the cytochalasin A-blockable recognition stage, nor for 51Cr release from injured target cells. Models for the lethal hit process are discussed, which are compatible with the observed requirement for certain hexoses unrelated to their capacity to serve as sources of energy.
Rudder: A Cross Lingual Video and Text Retrieval Dataset (2021)

Video retrieval using natural language queries requires learning semantically meaningful joint embeddings between the text and the audio-visual input. Often, such joint embeddings are learnt using pairwise (or triplet) contrastive loss objectives which cannot give enough attention to 'difficult-to-retrieve' samples during training. This problem is especially pronounced in data-scarce settings where the data is relatively small (10% of the large scale MSR-VTT) to cover the rather complex audio-visual embedding space. In this context, we introduce Rudder - a multilingual video-text retrieval dataset that includes audio and textual captions in Marathi, Hindi, Tamil, Kannada, Malayalam and Telugu. Furthermore, we propose to compensate for data scarcity by using domain knowledge to augment supervision. To this end, in addition to the conventional three samples of a triplet (anchor, positive, and negative), we introduce a fourth term - a partial - to define a differential margin based partialorder loss. The partials are heuristically sampled such that they semantically lie in the overlap zone between the positives and the negatives, thereby resulting in broader embedding coverage. Our proposals consistently outperform the conventional max-margin and triplet losses and improve the state-of-the-art on MSR-VTT and DiDeMO datasets. We report benchmark results on Rudder while also observing significant gains using the proposed partial order loss, especially when the language specific retrieval models are jointly trained by availing the cross-lingual alignment across the language-specific datasets.

Acoustic sensing with a single coiled monomode fiber (1980)

A single monomode fiber-optic acoustic sensor is proposed. The acoustic wave differentially changes the phase velocities of the polarization eigenmodes in a tension-coiled fiber, leading to a polarization rotation of the transmitted light. Sensitivities exceeding those of multimode fiber-optic hydrophones and ~40 times less than those of the two-fiber interferometric sensor should be realizable while environmental instability problems and the sensor complexity are significantly reduced.
Enantioselective Synthesis of Anti Homoallylic Alcohols from Terminal Alkynes and Aldehydes Based on Concomitant Use of a Cationic Iridium Complex and a Chiral Phosphoric Acid (2013)

We report a highly diastereo- and enantioselective synthesis of anti homoallylic alcohols from terminal alkynes via (E)-1-alkenylboronates based upon two catalytic reactions: a cationic iridium complex-catalyzed olefin transposition of (E)-1-alkenylboronates and a chiral phosphoric acid-catalyzed allylation reaction of aldehydes.

Transferable Vancomycin Resistance in a Community-Associated MRSA Lineage (2014)

We report the case of a patient from Brazil with a bloodstream infection caused by a strain of methicillin-resistant Staphylococcus aureus (MRSA) that was susceptible to vancomycin (designated BR-VSSA) but that acquired the vanA gene cluster during antibiotic therapy and became resistant to vancomycin (designated BR-VRSA). Both strains belong to the sequence type (ST) 8 community-associated genetic lineage that carries the staphylococcal chromosomal cassette mec (SCCmec) type IVa and the S. aureus protein A gene (spa) type t292 and are phylogenetically related to MRSA lineage USA300. A conjugative plasmid of 55,706 bp (pBRZ01) carrying the vanA cluster was identified and readily transferred to other staphylococci. The pBRZ01 plasmid harbors DNA sequences that are typical of the plasmid-associated replication genes rep24 or rep21 described in community-associated MRSA strains from Australia (pWBG745). The presence and dissemination of community-associated MRSA containing vanA could become a serious public health concern.
Influence of Bainite Fraction on Improving Mechanical Properties of Quenched and Tempered High Silicon Steel (2019)

Martensitic steels are characterized by high strength which, on the other hand, is offset by considerable brittleness. This drawback can be partly corrected by tempering, at the cost of reduced final strength. If steel is alloyed with a sufficient amount of silicon, an optimum heat treatment sequence can produce a mixed microstructure consisting of martensite and carbide-free bainite. In various microstructures of this composition with identical grain size, mechanical properties would be dictated predominantly by the fraction of bainite. This article deals with designing a heat treatment sequence for a low-alloy steel. It is part of a research into the impact of bainite fraction on mechanical properties of materials with martensitic-bainitic microstructure. At an appropriate ratio of martensite and bainite, a steel with 0.42 % C can exhibit strengths above 2200 MPa at A5mm elongation of more than 17 %.
IPCA, an architecture for intelligent control (2002)

IPCA (Intelligent Process Control Architecture) is an architecture for flexible, intelligent control. IPCA is rooted in the generic task (GT) approach to knowledge-based systems and incorporates plan generation and real-time plan execution monitoring components. The plan generation component produces a state-based process control plan representation which typically contains a collection of possible paths from initial to desired process states. Selection of the precise path taken through the process control plan is determined by a plan execution monitoring component. The plan execution monitor incrementally determines in real time appropriate partial paths through the process control plan based on sensory input gathered from real-time process monitoring. This real-time selection of appropriate plan fragments and control methods contained in the process control plan is facilitated through the use of a sponsor-selector mechanism. The usefulness of this approach to intelligent control is demonstrated by applying the architecture to the control of a microwave-based composite material fabrication process. Experimental results demonstrate the effectiveness of IPCA in this domain.
Stack Effluent Monitoring for an Operating Four Reactor Unit Candu Nuclear Station (1984)

Gaseous effluents from an operating four reactor unit CANDU power station are monitored for radioactive particulates, iodines, noble gases and tritium to ensure compliance with approved derived emission limits. The four types of stack effluent monitors used on each of ten stacks are described. The total stack flow at a four reactor unit station is about 10 times that at a single unit station, hence there is the need for monitors with an order of magnitude greater sensitivity at the four unit stations. This need has been met by optimizing standard measurement techniques for particulate and iodine detection, and by introducing a novel technique for noble gas loss determination that provides several orders of magnitude increased sensitivity over traditional methods of detection. In addition, the use of a simple silica-gel desiccant to extract moisture from the sample stream has proven highly accurate and reliable for tritium monitoring purposes.
PREX1 integrates G protein-coupled receptor and phosphoinositide 3-kinase signaling to promote glioblastoma invasion (2016)

A defining feature of the brain cancer glioblastoma is its highly invasive nature. When glioblastoma cells are isolated from patients using serum free conditions, they accurately recapitulate this invasive behaviour in animal models. The Rac subclass of Rho GTPases has been shown to promote invasive behaviour in glioblastoma cells isolated in this manner. However the guanine nucleotide exchange factors responsible for activating Rac in this context have not been characterized previously. PREX1 is a Rac guanine nucleotide exchange factor that is synergistically activated by binding of G protein αγ subunits and the phosphoinositide 3-kinase pathway second messenger phosphatidylinositol 3,4,5 trisphosphate. This makes it of particular interest in glioblastoma, as the phosphoinositide 3-kinase pathway is aberrantly activated by mutation in almost all cases. We show that PREX1 is expressed in glioblastoma cells isolated under serum-free conditions and in patient biopsies. PREX1 promotes the motility and invasion of glioblastoma cells, promoting Rac-mediated activation of p21-associated kinases and atypical PKC, which have established roles in cell motility. Glioblastoma cell motility was inhibited by either inhibition of phosphoinositide 3-kinase or inhibition of G protein βγ subunits. Motility was also inhibited by the generic dopamine receptor inhibitor haloperidol or a combination of the selective dopamine receptor D2 and D4 inhibitors L-741,626 and L-745,870. This establishes a role for dopamine receptor signaling via G protein βγ subunits in glioblastoma invasion and shows that phosphoinositide 3-kinase mutations in glioblastoma require a context of basal G protein-coupled receptor activity in order to promote this invasion.
Targeting Autophagy to Counteract Obesity-Associated Oxidative Stress (2021)

Reactive oxygen species (ROS) operate as key regulators of cellular homeostasis within a physiological range of concentrations, yet they turn into cytotoxic entities when their levels exceed a threshold limit. Accordingly, ROS are an important etiological cue for obesity, which in turn represents a major risk factor for multiple diseases, including diabetes, cardiovascular disorders, non-alcoholic fatty liver disease, and cancer. Therefore, the implementation of novel therapeutic strategies to improve the obese phenotype by targeting oxidative stress is of great interest for the scientific community. To this end, it is of high importance to shed light on the mechanisms through which cells curtail ROS production or limit their toxic effects, in order to harness them in anti-obesity therapy. In this review, we specifically discuss the role of autophagy in redox biology, focusing on its implication in the pathogenesis of obesity. Because autophagy is specifically triggered in response to redox imbalance as a quintessential cytoprotective mechanism, maneuvers based on the activation of autophagy hold promises of efficacy for the prevention and treatment of obesity and obesity-related morbidities.
Involvement of the Fcγ Receptor in a Chronic N-Methyl-4-phenyl-1,2,3,6-tetrahydropyridine Mouse Model of Dopaminergic Loss (2011)

Although there is growing evidence for a role of the innate immune response in Parkinson's disease, the nature of any humoral response in dopaminergic degeneration is uncertain. Here we report on a protracted N-methyl-4-phenyl-1,2,3,6-tetrahydropyridine model of dopaminergic death that potentially allows a more full adaptive humoral response to develop. Rag2 mutant mice that lack the full adaptive response (deficient in both T and B cells) are resistant to dopaminergic death and behavioral deficiencies in this model. These mice are resensitized after reconstitution with WT splenocytes. To more directly provide evidence for humoral/IgG involvement, we show that deficiency of Fcγ receptors, which are critical for activation of macrophages/microglia by binding to IgGs, is also protective in this protracted model. FcγR-deficient mice display improved behavior and impaired microglial activation. Interestingly, however, Rag2 mutant but not FcγR-deficient mice are resistant to a more standard N-methyl-4-phenyl-1,2,3,6-tetrahydropyridine paradigm where death is more rapid. Taken together, these data indicate that, provided sufficient time, the humoral arm of the adaptive immune system can play a critical functional role in modulating the microglial response to dopaminergic degeneration and suggest that this humoral component may participate in degeneration in Parkinson's disease.
Online real-time presentation of virtual experiences forexternal viewers (2012)

Externally observing the experience of a participant in a virtual environment is generally accomplished by viewing an egocentric perspective. Monitoring this view can often be difficult for others to watch due to unwanted camera motions that appear unnatural and unmotivated. We present a novel method for reducing the unnaturalness of these camera motions by minimizing camera movement while maintaining the context of the participant's observations. For each time-step, we compare the parts of the scene viewed by the virtual participant to the parts of the scene viewed by the camera. Based on the similarity of these two viewpoints we next determine how the camera should be adjusted. We present two means of adjustment, one which continuously adjusts the camera and a second which attempts to stop camera movement when possible. Empirical evaluation shows that our method can produce paths that have substantially shorter travel distances, are easier to watch and maintain the original observations of the participant's virtual experience.
Mercaptoundecanoic Acid Capped Palladium Nanoparticles in a SAPO 34 Membrane: A Solution for Enhancement of H2/CO2 Separation Efficiency (2014)

In this work, the high quality Pd/SAPO 34 membranes were grown on the support using a secondary (seeded) growth hydrothermal technique followed by insertion of 11-mercaptoundecanoic acid capped palladium (MUA-Pd) nanoparticles (NPs) to the membrane surface. For this, first, the indigenous low cost clay-alumina support was treated with poly diallyldimethylammonium chloride (PolyDADMAC) polymer, and subsequently, a seed layer of SAPO 34 crystals was deposited homogeneously in a regular orientation. Since PolyDADMAC is a high charge density cationic polymer, it assisted in reversing the charge of the support surface and produced an attractive electrostatic interaction between the support and zeolite crystals. This may facilitate the zeolite grain orientation in the synthesized membrane layer. Here, the Pd NPs were deposited in the membrane matrix by a simple dip-coating method. After thermal treatment of the Pd/SAPO 34 membrane, the defects were formed because of the removal of the structure-directing agent (SDA) from the zeolite pores but the presence of Pd NPs, which were entrapped inside the nonzeolitic pores and clogged the defects of the membrane. Field emission scanning electron microscopy (FESEM) and elemental mapping of the membrane cross-section confirmed that most of the Pd NPs were deposited at the interface of the membrane and the support layer which may increase the membrane efficiency, i.e., separation factor, as well as permeability of H2 through the membrane. As the membrane structure was associated with the oriented crystal, the pores were more aligned and permeation adequacy of H2 through the membrane enhanced. These membranes have a relative hydrogen permeance of 14.8 × 10(-7) mol·m(-2)·s(-1)·Pa(-1). The selectivity of H2/CO2 based on single gas permeation was 10.6, but for the mixture gas (H2/CO2 55:45), the H2/CO2 mixture separation factor increased up to 20.8 at room temperature. It is anticipated that this technique may be useful for making a defect free membrane and also a hydrogen selective Pd loaded membrane with lower cost (as the quantity of Pd is low) which can be utilized for a "clean energy" related application.
Prosthetic replacement of the ocular surface ecosystem: impact at 5 years (2015)

PROSE treatment offers continued benefit, as defined by improved visual function and continued device wear at 5 years, in patients with complex corneal disease. Patients with distorted cornea have a higher rate of continued wear at 5 years than patients with OSD, although this is not true among all subgroups within OSD.
Hierarchical memory system design for a heterogeneous multi-core processor (2008)

Multi-core architecture has become hot issue recently both for performance and power consideration. Memory system is the bottleneck under this circumstance. A multi-core architecture using simple cores based on transport triggered architecture is proposed. This architecture has a uniform programming view. The memory system design exploration and optimization is done and a hierarchical memory system is designed. A balanced memory bandwidth is provided to the multi-core architecture.
Rapid Opiate Detoxification (1996)

We report on clinical and practical aspects of treatment of opiate addiction with a relatively new approach, rapid opiate detoxification (ROD). The goal is to induce rapid narcotic withdrawal in a controlled environment using narcotic antagonists while suppressing withdrawal symptoms with sedative drugs, thus effecting a dramatic abbreviation of the traditional withdrawal schedule. Twenty-five consecutive heroin-addicted patients presenting for detoxification were treated at a university hospital. There were 14 women and 11 men, with a mean age 32.6 years (range, 24-48). They underwent 29 separate detoxifications over a 4-month period. All but 3 of the detoxifications were effected with ROD. Several different techniques were used over the 4-month period, ranging from intramuscular and oral sedation to intravenous sedation, paralysis, and intubation. Efficacy of detoxification was demonstrated for all patients undergoing ROD; all were given 50 mg of naltrexone PO prior to discharge, and none had withdrawal symptoms. (The three patients treated with abstinence were not so tested.) We derive three conclusions from this early clinical experience: First, ROD appears to be a valuable tool in the treatment of heroin addiction. ROD is an efficient, effective technique that can play an important role in an integrated rehabilitation program. Second, the optimal method of ROD is yet to be determined; a continuum of approaches is available. Third, ROD is probably most suited to designated outpatient centers.

A safe robot system for craniofacial surgery (2002)

The ultimate ambition of a robotic system in surgical theater has to be the safety of the involved humans: patient, physicians, nurses. In order to provide that claim the criteria of ergonomics, redundancy, short reaction time, and accuracy must be met. In contrast to many other surgical robotic applications we are studying complex bone cut trajectories which require several distinct orientations of the robot tool and milling cutter, respectively. Exact bone cuts are especially needed for bone repositionings placed at the human skull in craniofacial surgery. Therefore, the system has to be flexible enough to keep the capability of changing the patient's position during the intra-operative phase. This paper introduces the overall concept and realization of the system.
