Automatic Insertion of Low Power Annotations in RTL for Pipelined Microprocessors (2006)

We propose instruction-driven slicing, a technique for annotating microprocessor descriptions at the register transfer level (RTL) in order to achieve lower power dissipation. Our technique automatically annotates existing RTL code to optimize the circuit for lowering power dissipated by switching activity. Our technique can be applied at the architectural level as well, achieving similar power gains. We demonstrate our technique on architectural and RTL models of a 32-bit OpenRISC processor (OR1200), showing power gains for the SPEC2000 benchmarks
ECGSIM: an interactive tool for studying the genesis of QRST waveforms (2004)

The resulting transfer factors were implemented in a simulation program. The program allows the user to make interactive changes in the timing of depolarisation and repolarisation on the ventricular surface, as well as changing the local source strength, and to inspect or document the effect of such changes instantaneously on electrograms and body surface potentials, visualised by waveforms as well as by potential maps and movies. The entire simulation package can be installed free of charge from www.ecgsim.org.
RenderAnts (2009)

We present RenderAnts, the first system that enables interactive Reyes rendering on GPUs. Taking RenderMan scenes and shaders as input, our system first compiles RenderMan shaders to GPU shaders. Then all stages of the basic Reyes pipeline, including bounding/splitting, dicing, shading, sampling, compositing and filtering, are executed on GPUs using carefully designed data-parallel algorithms. Advanced effects such as shadows, motion blur and depth-of-field can also be rendered. In order to avoid exhausting GPU memory, we introduce a novel dynamic scheduling algorithm to bound the memory consumption during rendering. The algorithm automatically adjusts the amount of data being processed in parallel at each stage so that all data can be maintained in the available GPU memory. This allows our system to maximize the parallelism in all individual stages of the pipeline and achieve superior performance. We also propose a multi-GPU scheduling technique based on work stealing so that the system can support scalable rendering on multiple GPUs. The scheduler is designed to minimize inter-GPU communication and balance workloads among GPUs. We demonstrate the potential of RenderAnts using several complex RenderMan scenes and an open source movie entitled Elephants Dream. Compared to Pixar's PRMan, our system can generate images of comparably high quality, but is over one order of magnitude faster. For moderately complex scenes, the system allows the user to change the viewpoint, lights and materials while producing photorealistic results at interactive speed.
Field Programmable Stateful Logic Array (2011)

Recently, researchers have demonstrated that memristive switches can be used to implement logic and latches as well as memory and programmable interconnects. In this paper, we propose a novel stateful logic pipeline architecture based on memristive switches. The proposed architecture mapped to the field programmable nanowire interconnect fabric produces a field programmable stateful logic array, in which general-purpose computation functions can be implemented by configuring only nonvolatile nanowire crossbar switches. CMOS control switches are used to isolate stateful logic units so that multiple operations can be executed in parallel. Since basic operation of the stateful logic, namely, material implication, cannot fan out, a new basic AND operation which can duplicate output is proposed. The basic unit of the proposed architecture is designed to execute multiple basic operations concurrently in a step so that each basic unit implements a large fan-in OR or NOR gate. The fine-grain ultradeep constant-throughput pipeline properties pose new design automation problems. We address some of the issues, in particular logic representation using OR-inverter graphs, two-level optimization synthesis strategy, data synchronization with data forwarding, stall-free pipelined finite state machines, and constraints for synthesis and mapping onto the fabric.
Reduced Differentiation Efficiency of Murine Embryonic Stem Cells in Stirred Suspension Bioreactors (2009)

The use of embryonic stem cells (ESCs) for regenerative medicine has generated increased attention due to the favorable attributes of these cells; namely, they are pluripotent and possess long-term self-renewal capacity. The initial aims of the present study were: (i) to use stirred suspension bioreactors to expand and differentiate ESCs into osteogenic and chondrogenic cell types and (ii) to explore if these ESC-derived cells influenced skeletal healing in an in vivo fracture model. We show that differentiation protocols used in static culture are insufficient when applied directly to suspension culture bioreactors. Moreover, when bioreactor-differentiated cells are transplanted into a burr-hole defect in bone, severe disruption of the bone architecture was noted at the fracture site, as determined by microcomputed tomography (microCT) imaging and histopathology. Further characterization of the bioreactor-differentiated cultures revealed that a subpopulation of cells in the resulting aggregates expressed the pluripotency marker Oct-4 in the nucleus. Nuclear Oct-4 expression persisted even after 30 days of culture in the absence of leukemia inhibitory factor (LIF). Remarkably, and unlike ESCs differentiated into skeletal cell types in static cultures, bioreactor-differentiated aggregates implanted subcutaneously into SCID mice formed teratomas. The development of effective ESC differentiation protocols for suspension bioreactors will require a more complete understanding of the environmental conditions within these culture systems and the influence that these conditions have on the regulation of pluripotency and differentiation in ESCs.
Bone-Forming Capacity and Biodistribution of Bone Marrow-Derived Stromal Cells Directly Loaded into Scaffolds: A Novel and Easy Approach for Clinical Application of Bone Regeneration (2015)

In the context of clinical applications of bone regeneration, cell seeding into scaffolds needs to be safe and easy. Moreover, cell density also plays a crucial role in the development of efficient bone tissue engineering constructs. The aim of this study was to develop and evaluate a simple and rapid cell seeding procedure on hydroxyapatite/β-tricalcium phosphate (HA/βTCP), as well as define optimal cell density and control the biodistribution of grafted cells. To this end, human bone marrow-derived stromal cells (hBMSCs) were seeded on HA/βTCP scaffolds, and we have compared bone formation using an ectopic model. Our results demonstrated a significantly higher bone-forming capacity of hBMSCs directly loaded on HA/βTCP during surgery compared to hBMSCs preseeded for 7 days in vitro on HA/βTCP before ectopic implantation. The extent of new bone formation increases with increasing hBMSC densities quantitatively, qualitatively, and in frequency. Also, this study showed that grafted hBMSCs remained confined to the implantation site and did not spread toward other tissues, such as liver, spleen, lungs, heart, and kidneys. In conclusion, direct cell loading into a scaffold during surgery is more efficient for bone regeneration, as well as quick and safe. Therefore direct cell loading is suitable for clinical requirements and cell production control, making it a promising approach for orthopedic applications. Moreover, our results have provided evidence that the formation of a mature bone organ containing hematopoietic islets needs a sufficiently high local density of grafted hBMSCs, which should guide the optimal dose of cells for clinical use.
Autoradiographic localization and biochemical characterization of peripheral type CCK receptors in rat CNS using highly selective nonpeptide CCK antagonists (1987)

Two potent and highly selective nonpeptide antagonists, L-365,031 [1- methyl-3-(4-bromobenzoyl)amino-5-phenyl-3H-1,4 benzodiazepin-2-one] and 3H-L-364,718 [1-methyl-3-(2-indoloyl)amino-5-phenyl-3H-1,4 benzodiazepin-2-one] were used to localize “peripheral” CCK receptors in rat brain. In autoradiographic experiments, L-365,031 displaced 125I- Bolton Hunter CCK-8 binding from the interpeduncular nucleus (IPN) (IC50 = 7 X 10(-8) M), the area postrema (AP), and the nucleus tractus solitarius (NTS) without influencing specific binding to other areas, such as the cerebral cortex or the spinal tract of the trigeminal nerve. Desulfated CCK preferentially inhibited 125I-CCK binding to cerebral cortex (IC50 = 7 X 10(-8) M) rather than IPN (IC50 greater than 1 X 10(-6) M) or AP-NTS. In the medulla the localization of 3H-L- 364,718 binding was similar to L-365,031-sensitive 125I-CCK-8 binding and was found in the AP and medial, but not lateral, aspects of the NTS. In membranes prepared from IPN, NTS, and AP, 3H-364,718 binding was of high affinity (Kd = 0.14 nM), saturable (Bmax = 20 fmol/mg protein), and inhibited by compounds previously shown to act at pancreatic CCK receptors. The receptors labeled by 3H-364,718 were modulated by guanyl nucleotide, which reduced agonist affinity 10-fold without affecting antagonist binding. The localization and high density of CCK receptors in AP and NTS suggest that these receptors may play an important role in processing sensory afferent information.
A brief overview of secondary zinc anode development: The key of improving zinc-based energy storage systems (2017)

Electricity will increasingly be produced from sources that are geographically decentralized and/or intermittent in their nature. In consequents, there is an urgent need to increase the storage of energy to guarantee the continuity of energy supply. Rechargeable zinc-air battery is a promising technology due to the high theoretical energy density and the abundant and environmentally benign materials that are used. In the state of the art, the information about secondary zinc anode for rechargeable zinc-air batteries is scarce. The main development of the technology has been lately concentrated on the bifunctional air electrodes while the used zinc anode is mainly based on a planar zinc electrode providing low specific energy densities for the full system. This overview compiles the available information in the literature regarding the development and manufacturing of zinc anodes for electrical rechargeable batteries applications, where secondary porous zinc electrodes are generally desired. In this context, the zinc-based anode electrode composition (namely, active material, binder, conductive material, current collector, and additives), pretreatments, and processing techniques are described and their impact on the zinc anode performance analyzed.
Automatic personality perception: Prediction of trait attribution based on prosodic features extended abstract (2015)

This paper proposes a prosody based approach for Automatic Personality Perception. Social psychology has shown that whenever we listen to a voice for the first time, we spontaneously and unconsciously attribute personality traits to the speaker. The attribution process is not necessarily accurate, but it is important because it shapes our behavior towards others. The experiments of this work are performed over a corpus of 640 speech samples (322 individuals in total) assessed in terms of speaker's personality traits by 11 judges. The results show that it is possible to predict some of the personality traits with accuracy higher than 70%. The effect of different prosodic features has also been analyzed and compared with findings in the psychological literature.
GENIUS: AN INTEGRATED ENVIRONMENT FOR SUPPORTING THE DESIGN OF GENERIC AUTOMATED NEGOTIATORS (2012)

The design of automated negotiators has been the focus of abundant research in recent years. However, due to difficulties involved in creating generalized agents that can negotiate in several domains and against human counterparts, many automated negotiators are domain specific and their behavior cannot be generalized for other domains. Some of these difficulties arise from the differences inherent within the domains, the need to understand and learn negotiators’ diverse preferences concerning issues of the domain, and the different strategies negotiators can undertake. In this paper we present a system that enables alleviation of the difficulties in the design process of general automated negotiators termed G enius , a G eneral E nvironment for N egotiation with I ntelligent multi‐purpose U sage S imulation. With the constant introduction of new domains, e‐commerce and other applications, which require automated negotiations, generic automated negotiators encompass many benefits and advantages over agents that are designed for a specific domain. Based on experiments conducted with automated agents designed by human subjects using G enius we provide both quantitative and qualitative results to illustrate its efficacy. Finally, we also analyze a recent automated bilateral negotiators competition that was based on G enius . Our results show the advantages and underlying benefits of using G enius and how it can facilitate the design of general automated negotiators.
Elimination of ‘‘pair’’ defects from GaAs layers grown by molecular beam epitaxy (1985)

In addition to ‘‘oval’’ defects, ‘‘pair’’ defects are observed on molecular beam epitaxially grown GaAs wafers. In this letter it is demonstrated that these defects originate from sulfur on the substrate surface caused by a 4:1:1 (H2SO4:H2O2:H2O) etch. The defects can be completely eliminated by dipping the substrate in 30% HCl solution for 5 min following a sulfuric acid etch.
A genetic association study between growth differentiation factor 5 (GDF 5) polymorphism and knee osteoarthritis in Thai population (2011)

These data suggested that GDF5 polymorphism has an association with knee OA in Thai ethnic. This finding also supports the hypothesis that OA has an important genetic component in its etiology, and GDF5 protein might play important role in the pathophysiology of the disease.
1.3 µm range 40 GHz quantum-dot mode-locked laser under external continuous wave light injection or optical feedback (2010)

We have investigated the jitter, repetition frequency and spectra of a quantum-dot mode-locked laser operating at 40 GHz under continuous wave external light injection using an external cavity laser or under optical feedback.For the case of the continuous wave light injection we realized a shift of the optical emission of up to 15 nm.With optical feedback we have found a ninefold jitter reduction, down to a record low value of 1 ps over an integration range from 10 kHz to 1 GHz.Optical feedback fixes the repetition frequency while changing current and voltage applied to the diode.This is due to the fact that stable mode locking occurs at frequencies which are integers of the feedback loop frequency.
Self-Protection of Turbo- and LDPC-Coded OFDM Systems against Non-Stationary Disturbances (2006)

This paper presents a method to protect turbo- and low density parity check (LDPC)-coded OFDM systems against non-stationary disturbances without using external codes. The technique does not alter the structure of the original code and the constellation mapper/demapper, but requires the insertion of a so-called self-protection unit (SPU) between the coding and constellation mapping units. The SPU enhances the burst-error-correction capabilities of turbo and LDPC codes by combining erasure-decoding, subframing (i.e., reordering the coded data into subframes), and the optional use of subframe interleaving to spread error bursts. Self-protected systems exhibit a reduced latency and storage capacity compared to classical channel interleaving schemes with similar protection level.
PLC-cache: Endurable SSD cache for deduplication-based primary storage (2014)

Data deduplication techniques improve cost efficiency by dramatically reducing space needs of storage systems. SSD-based data cache has been adopted to remedy the declining I/O performance induced by deduplication operations in the latency-sensitive primary storage. Unfortunately, frequent data updates caused by classical cache algorithms (e.g., FIFO, LRU, and LFU) inevitably slow down SSDs' I/O processing speed while significantly shortening SSDs' lifetime. To address this problem, we propose a new approach-PLC-Cache-to greatly improve the I/O performance as well as write durability of SSDs. PLC-Cache is conducive to amplifying the proportion of the Popular and Long-term Cached (PLC) data, which is infrequently written and kept in SSD cache in a long time period to catalyze cache hits, in an entire SSD written data set. PLC-Cache advocates a two-phase approach. First, non-popular data are ruled out from being written into SSDs. Second, PLC-Cache makes an effort to convert SSD written data into PLC-data as much as possible. Our experimental results based on a practical deduplication system indicate that compared with the existing caching schemes, PLC-Cache shortens data access latency by an average of 23.4%. Importantly, PLC-Cache improves the lifetime of SSD-based caches by reducing the amount of data written to SSDs by a factor of 15.7.
Proactive temperature balancing for low cost thermal management in MPSoCs (2008)

Designing thermal management strategies that reduce the impact of hot spots and on-die temperature variations at low performance cost is a very significant challenge for multiprocessor system-on-chips (MPSoCs). In this work, we present a proactive MPSoC thermal management approach, which predicts the future temperature and adjusts the job allocation on the MPSoC to minimize the impact of thermal hot spots and temperature variations without degrading performance. In addition, we implement and compare several reactive and proactive management strategies, and demonstrate that our proactive temperature-aware MPSoC job allocation technique is able to dramatically reduce the adverse effects of temperature at very low performance cost. We show experimental results using a simulator as well as an implementation on an UltraSPARC T1 system.
The synthesis of n-caproate from lactate: a new efficient process for medium-chain carboxylates production (2015)

A unique microbiome that metabolizes lactate rather than ethanol for n-caproate production was obtained from a fermentation pit used for the production of Chinese strong-flavour liquor (CSFL). The microbiome was able to produce n-caproate at concentrations as high as 23.41 g/L at a maximum rate of 2.97 g/L/d in batch trials without in-line extraction. Compared with previous work using ethanol as the electron donor, the n-caproate concentration increased by 82.89%. High-throughput sequencing analysis showed that the microbiome was dominated by a Clostridium cluster IV, which accounted for 79.07% of total reads. A new process for n-caproate production was proposed, lactate oxidation coupled to chain elongation, which revealed new insight into the well-studied lactate conversion and carbon chain elongation. In addition, these findings indicated a new synthesis mechanism of n-caproate in CSFL. We believe that this efficient process will provide a promising opportunity for the innovation of waste recovery as well as for n-caproate biosynthesis.
Distributed cooperative systems for advanced automation: tradeoffs (2002)

The nature and benefits of cooperative systems, which have the potential to provide control systems with functions that will reduce human workload, are examined. Three applications relevant to spacecraft control are discussed. They are coordination among human controllers of interdependent spacecraft subsystems, autonomous operations through distributed planning, and common resource management. The CoopES (cooperating expert systems) prototype, a set of distributed operating systems services and a set of agents with specific expertise in the Space Shuttle control domain, is described. The tradeoffs involved in using the cooperative approach are considered.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Human Limbs and Their Substitutes: Presenting Results of Engineering and Medical Studies of the Human Extremities and Application of the Data to the Design and Fitting of Artificial Limbs and to the Care and Training of Amputees (1955)

This is one of the best books published on prostheses. There has been a great need for an adequate description of prosthetic limbs and particularly one that is complete and up-to-date. This book satisfies this requirement. The general outline of the book is exceedingly well done. Practically each chapter is a monograph within itself, and the detailed drawings and photographs add much to the value of the volume. This book is timely, particularly in its first half, which deals with the newer concept of upper extremity prostheses. Prior to 10 years ago upper extremity prostheses were of little functional value. Through the research work conducted by the National Research Council, the Committee on Artificial Limbs, the Veterans Administration, and the University of California at Los Angeles, to mention only a few, the upper extremity prosthetic program has been given great impetus. The value of teamwork in the approach to the
The Factor VII-Platelet Interplay: Effectiveness of Recombinant Factor VIIa in the Treatment of Bleeding in Severe Thrombocytopathia (2000)

Recently, high-dose factor VIIa has been used to correct bleeding in patients with various thrombocytopathias including Glanzmann's thrombasthenia, Bernard-Soulier syndrome, and uremia. High-dose factor VIIa is postulated to act on platelets in the absence of tissue factor to activate factors IX and X and thus enhance thrombin generation. This enhanced thrombin generation might help provide hemostasis in patients with thrombocytopathias through several mechanisms. Enhanced thrombin generation would provide a strong signal for recruitment of other platelets. Also, enhanced fibrin deposition might provide mechanisms for bypassing the specific defect in thrombocytopathias. Thus, platelets from a patient with Bernard-Soulier syndrome might associate with fibrin by a glycoprotein IIb-IIIa-mediated mechanism. Also, platelets from a patient with Glanzmann's thrombasthenia might associate with fibrin through von Willebrand factor-mediated interactions with glycoprotein Ib-V-IX. Finally, enhanced thrombin generation on platelets would mean that fewer platelets are required for hemostasis.
On Composable System Timing, Task Timing, and WCET Analysis (2008)

The complexity of hardware and software architectures used in today's embedded systems make a hierarchical, composable timing analysis impossible. This paper describes the source of this complexity in terms of mechanisms and side effects that determine variations in the timing of single tasks and entire applications. Based on these observations, the paper proposes strategies to reduce the complexity. It shows the positive effects of these strategies on the timing of tasks and on WCET analysis.
