ATLAS: a chip-multiprocessor with transactional memory support (2007)

Chip-multiprocessors are quickly becoming popular in embedded systems. However, the practical success of CMPs strongly depends on addressing the difficulty of multithreaded application development for such systems. Transactional memory (TM) promises to simplify concurrency management in multithreaded applications by allowing programmers to specify coarse-grain parallel tasks, while achieving performance comparable to fine-grain lock-based applications. This paper presents ATLAS, the first prototype of a CMP with hardware support for transactional memory. ATLAS includes 8 embedded PowerPC cores that access coherent shared memory in a transactional manner. The data cache for each core is modified to support the speculative buffering and conflict detection necessary for transactional execution. The authors have mapped ATLAS to the BEE2 multi-FPGA board to create a full-system prototype that operates at 100MHz, boots Linux, and provides significant performance and ease-of-use benefits for a range of parallel applications. Overall, the ATLAS prototype provides an excellent framework for further research on the software and hardware techniques necessary to deliver on the potential of transactional memory
<title>Hierarchical audio encoder for network traffic adaptation</title> (1999)

In this paper, we describe modifications to the rate multicast audio tool to allow audio stream to be hierarchically encoded. This allows the rate of audio data transmission to be selected by the receiver. This is particularly useful in multicast sessions where many users participate with diverse connectivity. The hierarchical encoder also allows dynamic adjustment of the received data rate to network conditions. The algorithm is based upon a simple pulse code modulation scheme. Speech is sampled at 8,000 samples per second with 16 bits per sample. The bits are then divided into groups based on their overall relative importance to the sample. A base group is defined which provides a reasonable approximation to the sample, but which discards most details. Each successive group adds more detail. The groups, which together represent different resolutions, are sent as separate data streams. The receiver subscribes to a set of data streams such that the total data rate can feasibly be delivered by the network. Bandwidth usage and signal resolution are easily adapted by adding or dropping groups. Performance was evaluated based on continuity and intelligibility of the speech segments as well as bandwidth usage and loss.

Although a considerable amount of research in personality psychology has been done to conceptualize human personality, identify the “Big Five” dimensions, and explore the meaning of each dimension,...
<title>3D locator sets of opaque objects for phase retrieval</title> (1997)

Generating a 3D image can be accomplished by gathering 3D far-field heterodyne array data with multiple laser wavelengths and performing a 3D Fourier transform. However, since heterodyne detection is difficult at optical frequencies, the collection system can be greatly simplified if direct detection is performed instead. Then to reconstruct an image one would need a phase-retrieval algorithm. To assist the reconstruction algorithm, we place bounds on the support of the illuminated object, derived from the support of the autocorrelation function, which can be computed from the Fourier intensity data. We have developed 3D locator sets for getting tight bounds on the object support. These new locator sets are more powerful than those for 2D imaging, and some of them make explicit use of the fact that the illuminated opaque object is effectively a 2D surface embedded in 3D space. For those cases in which it is tight enough, the locator set itself may be all that we need to give an accurate height profile of the object.
Rapid service activation for personal communications access services (2002)

Based on cellular industry data, the anticipated growth and churn rate for the personal communications service (PCS) market translates into high numbers of service activation and deactivation orders for PCS service providers (PSPs). Thus, methods of achieving rapid service activation could result in great savings. The paper describes three methods, all of which rely on a mechanized PSPs sales agent access to LEC systems. It points out the security burdens associated with over-the-air activation, identifies a manual activation as a near-term possibility and an automated wireline method as a target.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Ultrasonic characterization of foods and drinks: Principles, methods, and applications (1997)

The use of ultrasonics as an analytical technique for providing information about the physicochemical properties of foods is becoming increasingly popular in the food industry. Ultrasound can be used to rapidly and nondestructively measure properties such as food composition, structure, flow rate, physical state, and molecular properties. As well as being used as an analytical instrument in the laboratory, ultrasound can also be used for continuous monitoring of food properties on-line during processing. This article critically reviews the current status of ultrasound in the food industry, presents the basic principles of ultrasonic testing of foods, and highlights areas where ultrasound will prove to be most useful in the future.
Histological and biochemical studies of a transplantable rat chondrosarcoma. (1979)

The Swarm rat chondrosarcoma, a spontaneously derived tumor maintained in Sprague-Dawley rats, was examined for its morphological and biochemical characteristics. The tumor matrix exhibited cartilage-like-staining properties. Cartilage-specific type II collagen was identified intracellularly and following hyaluronidase pretreatment in the extracellular matrix by means of immunofluorescent techniques with antitype II antibodies. Histological studies revealed a multinodular tumor structure. Type I and III collagens were found predominantly in the septa and stroma between the nodules. Various procedures for obtaining the maximal yield of viable cells from the tumor were compared. Under the culture conditions used, primary cell suspensions in short-term culture did not change their phenotypic expression regarding the synthesis of type II collagen. Biologically active polysomes and messenger RNA were isolated from cell suspensions, which proved to be a better source for such macromolecules than was the total tissue. The Swarm rat chondrosarcoma is therefore a useful model system for studying the biosynthesis of type II collagen. A similar methodology could be used to study human tumors. The macromolecular synthetic pattern of malignant sarcomas, particularly the pattern of structural matrix proteins, may provide a more rational classification scheme for these poorly understood human tumors.
Efficacy of adjuvant immunotherapy with cytokine-induced killer cells in patients with locally advanced gastric cancer (2012)

Adjuvant immunotherapy with CIK cells prolongs DFS in patients with locally advanced gastric cancer and significantly improves OS in patients with intestinal-type tumors. Intestinal-type tumors could be selected as an important indication for CIK-cell therapy. This treatment may help improve T-lymphocyte subset distribution and improve the host's immune functions, but multiple cycles are necessary for long-term therapeutic efficacy.
Conducted noise reduction of totem-pole bridgeless PFC converter using GaN HEMTs (2015)

The common mode (CM) noise mechanism of totem-pole bridgeless PFC converter is analyzed in this paper. The conducted noise performance of a bridgeless totem-pole PFC converter using GaN HEMTs is investigated under experimental conditions: 230V ac input, 390V dc output, and 50kHz switching frequency. The CM noise located around the input voltage zero-crossing of the converter is noticed to be significant. Therefore, a conducted noise reduction method is proposed in this paper. Experimental results showed that the conducted noise has been suppressed efficiently without deteriorating the converter's efficiency.
Characterization and functional analysis of <i>ABSCISIC ACID INSENSITIVE3</i>‐like genes from <i>Physcomitrella patens</i> (2006)

Although the moss Physcomitrella patens is known to respond to abscisic acid (ABA) by activating gene expression, the transcriptional components involved have not been characterized. Initially, we used the ABA-responsive Em promoter from wheat linked to beta-glucuronidase (GUS) to determine whether ABI3/VP1, transcriptional regulators in the ABA-signaling pathway in angiosperms, were similarly active in the ABA response of P. patens. We show by particle bombardment that ABI3 and VP1 affect Em-GUS expression in P. patens in a manner similar to angiosperms. We also show the involvement of ABI1 in the pathway, utilizing the abi1-1 mutant allele. We isolated three ABI3-like genes from P. patens. Using an Em-like ABA-responsive promoter from P. patens (PpLea1), we demonstrate that PpABI3A, only in the presence of ABA, strongly enhances PpLea1-GUS expression in P. patens. PpABI3A also enhances ABA-induced Em-GUS expression in P. patens. In barley aleurone, PpABI3A transactivates Em-GUS but to a lesser extent than VP1 and ABI3. PpABI3A:GFP is localized to the nucleus of both protonemal cells and barley aleurone, indicating that the nuclear localization signals are conserved. We show that at least a part of the inability of PpABI3A to fully complement the phenotypes of the Arabidopsis abi3-6 mutant is due to a weak interaction between PpABI3A and the bZIP transcription factor ABI5, as assayed functionally in barley aleurone and physically in the yeast-two-hybrid assay. Our data clearly demonstrate that P. patens will be useful for comparative structural and functional studies of components in the ABA-response pathway such as ABI3.
Compositional and in Vitro Evaluation of Nonwoven Type I Collagen/Poly-dl-lactic Acid Scaffolds for Bone Regeneration (2015)

Poly-dl-lactic acid (PDLLA) was blended with type I collagen to attempt to overcome the instantaneous gelation of electrospun collagen scaffolds in biological environments. Scaffolds based on blends of type I collagen and PDLLA were investigated for material stability in cell culture conditions (37 °C; 5% CO2) in which post-electrospinning glutaraldehyde crosslinking was also applied. The resulting wet-stable webs were cultured with bone marrow stromal cells (HBMSC) for five weeks. Scanning electron microscopy (SEM), confocal laser scanning microscopy (CLSM), Fourier transform infra-red spectroscopy (FTIR) and biochemical assays were used to characterise the scaffolds and the consequent cell-scaffold constructs. To investigate any electrospinning-induced denaturation of collagen, identical PDLLA/collagen and PDLLA/gelatine blends were electrospun and their potential to promote osteogenic differentiation investigated. PDLLA/collagen blends with w/w ratios of 40/60, 60/40 and 80/20 resulted in satisfactory wet stabilities in a humid environment, although chemical crosslinking was essential to ensure long term material cell culture. Scaffolds of PDLLA/collagen at a 60:40 weight ratio provided the greatest stability over a five-week culture period. The PDLLA/collagen scaffolds promoted greater cell proliferation and osteogenic differentiation compared to HMBSCs seeded on the corresponding PDLLA/gelatine scaffolds, suggesting that any electrospinning-induced collagen denaturation did not affect material biofunctionality within 5 weeks in vitro.
Experiments on an RGB-D Wearable Vision System for Egocentric Activity Recognition (2014)

This work describes and explores novel steps towards activity recognition from an egocentric point of view. Activity recognition is a broadly studied topic in computer vision, but the unique characteristics of wearable vision systems present new challenges and opportunities. We evaluate a challenging new publicly available dataset that includes trajectories of different users across two indoor environments performing a set of more than 20 different activities. The visual features studied include compact and global image descriptors, including GIST and a novel skin segmentation based histogram signature, and state-of-the art image representations for recognition, including Bag of SIFT words and Convolutional Neural Network (CNN) based features. Our experiments show that simple and compact features provide reasonable accuracy to obtain basic activity information (in our case, manipulation vs. non-manipulation). However, for finer grained categories CNN-based features provide the most promising results. Future steps include integration of depth information with these features and temporal consistency into the pipeline.
Stacked Hourglass Network Joint with Salient Region Attention Refinement for Face Alignment (2019)

Localizing facial landmarks is a fundamental step in facial image analysis. However, the problem continues to be challenging in condition of large variations caused by pose disparity, illumination, expression and occlusion. In this paper, we propose a coarse-to-fine framework which joints stacked hourglass network and salient region attention refinement for robust face alignment. To achieve this, we firstly develop a multi-scale region learning module (MSL) to analyze the structure and texture information at different facial region and extract strong discriminative deep feature. Then we employ a novel convolutional neural network named stacked hourglass network (SHN) for heatmap regression and initial facial landmarks prediction. Moreover, we present a salient region attention module (SRA) to extract precise feature based on the heatmap regression, and the filtered feature is used for landmarks refinement. The extensive experimental results on two public datasets, including 300W and COFW, confirm the validity of our model.
Gastrointestinal motility disorder assessment in systemic sclerosis (2013)

GI involvement is very frequent in SSc patients. Oesophagus and small bowel are more frequently impaired, whereas delayed gastric emptying is less common.
Analogues of arginine vasopressin and its agonist and antagonist modified in the N‐terminal part of the molecule with <scp>l</scp>‐<i>β</i>‐homophenylalanine (2005)

In continuation of our efforts to elucidate the role of positions 2 and 3 in arginine vasopressin (AVP) and its analogues, we designed and synthesized peptides modified in these positions with l-beta-homophenylalanine (beta-Hph). Two of them had just this single modification, the next two peptides are analogues of the V2 agonist, namely [3-mercaptopropionic acid (Mpa)1]AVP (dAVP). The last two compounds were designed by substitution of positions 2 or 3 of a potent V(1a) antagonist, [1-mercaptocyclohexaneacetic acid (Cpa)1]AVP, with beta-Hph. All the peptides were tested for their pressor and antidiuretic and uterotonic in vitro activities in the rat. All the activities tested have been found to be significantly decreased. Three analogues, i.e. [Mpa(1),beta-Hph2]AVP, [Cpa1,beta-Hph2]AVP, [Cpa1,beta-Hph3]AVP, turned out to be uterotonic antagonists with pA2 = 6.3 +/- 0.2, 6.3 +/- 0.1, 6.0 +/- 0.3 respectively. The last one exhibited antipressor properties also (pA2 = 6.4 +/- 0.1).
Towards omnidirectional, large scale, full polarization, and broadband practical invisibility cloaks: challenges and progress (2014)

Invisibility cloaks have experienced a tremendous development in the past few years, but the current technologies to convert the cloaks into practical applications are still facing numerous bottlenecks. In this paper, we provide the review of the challenges and recent progress in the invisibility cloaks from a practical perspective. In particular, the following key challenges such as non-extreme parameters, homogeneity, omnidirectivity, full polarization, large scale and broad band are addressed. We analyze the physical mechanisms behind the challenges and consequently evaluate the merits and defects of the recent solutions. We anticipate some compromises on the ideal cloaks are required in order to achieve practical invisibility cloaks in the future.
Probiotics and nutrients for the first 1000 days of life in the developing world (2012)

Clinically proven probiotics are, for the most part, not available in the developing world and certainly not affordable for the majority of people. This is unconscionable considering these products can alleviate diarrhoea and various infections, which are by far the major cause of death in children and in adults who are HIV positive. Indeed, some of these products have been proven in developing world settings. Distribution networks exist along with pharmacies and clinics that dispense drugs and products that require refrigeration. So, are lack of profit or company resources the problem? Our university has shown that alternative community based kitchen models that produce probiotics can be established. These empower local people, are socially responsible, produce affordable products and deliver benefits to over 3,000 children and adults daily. Surely, other institutions and corporations can multiply this effect and develop social business models across the developing world that are supported by clinical and basic science studies? In this review, we will discuss the application of probiotics and selected nutrients in the first 1000 days of life, a critical timepoint which is particularly challenging in resource disadvantaged countries.
Software-Defined Networking Approaches for Link Failure Recovery: A Survey (2020)

Deployment of new optimized routing rules on routers are challenging, owing to the tight coupling of the data and control planes and a lack of global topological information. Due to the distributed nature of the traditional classical internet protocol networks, the routing rules and policies are disseminated in a decentralized manner, which causes looping issues during link failure. Software-defined networking (SDN) provides programmability to the network from a central point. Consequently, the nodes or data plane devices in SDN only forward packets and the complexity of the control plane is handed over to the controller. Therefore, the controller installs the rules and policies from a central location. Due to the central control, link failure identification and restoration becomes pliable because the controller has information about the global network topology. Similarly, new optimized rules for link recovery can be deployed from the central point. Herein, we review several schemes for link failure recovery by leveraging SDN while delineating the cons of traditional networking. We also investigate the open research questions posed due to the SDN architecture. This paper also analyzes the proactive and reactive schemes in SDN using the OpenDayLight controller and Mininet, with the simulation of application scenarios from the tactical and data center networks.
Measurements of Digital Signal Delay Variation Due to Dynamic Power Supply Noise (2005)

On-chip 100-ps/100-muV waveform accurate measurements on signal transition in a large-scale digital circuits clearly demonstrate the correlation of dynamic delay variation with power supply noise waveforms. An approximately linear dependence of delay increase with drop height holds under the existence of static IR drop, however, the coefficient of delay increase is strongly influenced by a dynamic power supply noise waveform. Another cause of delay variation is found as a distortion of signal waveforms during logic transition by dynamic power supply noise, where the process is sensitive not only to a noise waveform but also to a relative time difference among victim and aggressor pairs, which can be generally found in a design with multiple clock domains
A cost-effective modular phased array (2013)

The authors discuss a phased array antenna design consisting of multiple, modular, flat panels the number of which is determined by specific application requirements. Each panel has 512 antenna elements which are driven by their own Application Specific Integrated Circuits, in order to control the signal phase needed for electronic beam steering. Furthermore, the antenna elements can transmit (or receive) in orthogonal polarisation states. In the first embodiment, Ku-band microwave signals (receive over 10.95-12.75 GHz and transmit over 14.0-14.5 GHz) are phase-aligned, down converted to baseband and summed, permitting the receiver and the digital control circuitry to be fabricated on one low-cost SiGe ASIC. It is envisaged that this approach will be a cost-effective alternative to mechanically steered dish antennas for radar, satellite communication and point to point communications, while bearing the advantages of flat or conformal structure and no moving parts.
Coreactivity of Legionella pneumophila immune sera in the Mycoplasma pneumoniae complement fixation test (1982)

Sheep and guinea pigs were immunized with cellular and extracellular antigen from Legionella pneumophila bacteria. After immunization, the animals developed immunoglobulin G titers against the immunizing agent. The same sera were also tested in a Mycoplasma pneumoniae complement fixation test. All the preimmunization sera from sheep showed positive M. pneumoniae complement fixation tests of varying titers, with significant antibody rises in two of five sheep as a result of the Legionella immunizations. In contrast to the sheep, all the guinea pigs were negative in the M. pneumoniae complement fixation test, both in their preimmunization sera and after completion of the Legionella immunizations. The results obtained with the sheep sera may be explained as a nonspecific booster effect of Legionella bacteria upon previously elicited immune responses.
Architectural alternatives of wireless access through hybrid fiber/coax distribution plant (2002)

Due to the smaller microcell size, a limited distance transmission on the coaxial distribution plant is still required when using the hybrid fiber/coaxial (HFC) distribution plant to provide wireless access. It is found that the transmission capability of the coaxial distribution plant is generally better than that of the air interface. However, the available spectrum, especially in the upstream direction, is limited. Three architectural alternatives are identified. The first one uses the coaxial cables between the fiber node (FN) and first line amplifiers to provide radio frequency (RF) transmission with or without carrier frequency conversion. The second establishes fixed transmission links between the FN and radio ports using a simple digital modulation method such as QPSK. The third requires efficient transmission schemes and advanced media access protocols to establish a local area network (LAN) to provide flexible high rate wireless access services.
