Generating Facial Expressions for Speech (1996)

This article reports results from a program that produces high‐quality animation of facial expressions and head movements as automatically as possible in conjunction with meaning‐based speech synthesis, including spoken intonation. The goal of the research is as much to test and define our theories of the formal semantics for such gestures, as to produce convincing animation. Towards this end, we have produced a high‐level programming language for three‐dimensional (3‐D) animation of facial expressions. We have been concerned primarily with expressions conveying information correlated with the intonation of the voice: This includes the differences of timing, pitch, and emphasis that are related to such semantic distinctions of discourse as “focus,”“topic,” and “comment,”“theme” and “rheme,” or “given” and “new” information. We are also interested in the relation of affect or emotion to facial expression. Until now, systems have not embodied such rule‐governed translation from spoken utterance meaning to facial expressions. Our system embodies rules that describe and coordinate these relations: intonation/information, intonation/affect, and facial expressions/affect. A meaning representation includes discourse information: What is contrastive/background information in the given context, and what is the “topic” or “theme” of the discourse? The system maps the meaning representation into how accents and their placement are chosen, how they are conveyed over facial expression, and how speech and facial expressions are coordinated. This determines a sequence of functional groups: lip shapes, conversational signals, punctuators, regulators, and manipulators. Our algorithms then impose synchrony, create coarticulation effects, and determine affectual signals, eye and head movements. The lowest level representation is the Facial Action Coding System (FACS), which makes the generation system portable to other facial models.

Spatial and temporal targeting of gene expression in <i>Drosophila</i> by means of a tetracycline-dependent transactivator system (1998)

In order to evaluate the efficiency of the tetracycline-regulated gene expression system in Drosophila, we have generated transgenic lines expressing a tetracycline-controlled transactivator protein (tTA), with specific expression patterns during embryonic and larval development. These lines were used to direct expression of a tTA-responsive promoter fused to the coding region of either the beta-galactosidase or the homeotic protein Antennapedia (ANTP), under various conditions of tetracycline treatment. We found that expression of beta-galactosidase can be efficiently inhibited in embryos and larvae with tetracycline provided in the food, and that a simple removal of the larvae from tetracycline exposure results in the induction of the enzyme in a time- and concentration-dependent manner. Similar treatments can be used to prevent the lethality associated with the ectopic expression of ANTP in embryos and, subsequently, to control the timing of expression of the homeoprotein ANTP specifically in the antennal imaginal disc. Our results show that the expression of a gene placed under the control of a tetracycline-responsive promoter can be tightly controlled, both spatially by the regulatory sequences driving the expression of tTA and temporally by tetracycline. This provides the basis of a versatile binary system for controlling gene expression in Drosophila, with an additional level of regulation as compared to the general method using the yeast transcription factor GAL4.
Electromagnetic interference shielding effectiveness of monolayer graphene (2012)

We report the first experimental results on the electromagnetic interference (EMI) shielding effectiveness (SE) of monolayer graphene. The monolayer CVD graphene has an average SE value of 2.27 dB, corresponding to ~40% shielding of incident waves. CVD graphene shows more than seven times (in terms of dB) greater SE than gold film. The dominant mechanism is absorption rather than reflection, and the portion of absorption decreases with an increase in the number of graphene layers. Our modeling work shows that plane-wave theory for metal shielding is also applicable to graphene. The model predicts that ideal monolayer graphene can shield as much as 97.8% of EMI. This suggests the feasibility of manufacturing an ultrathin, transparent, and flexible EMI shield by single or few-layer graphene.
Effect of<i>Lactobacillus rhamnosus</i>CGMCC1.3724 supplementation on weight loss and maintenance in obese men and women (2013)

The present study investigated the impact of a Lactobacillus rhamnosus CGMCC1.3724 (LPR) supplementation on weight loss and maintenance in obese men and women over 24 weeks. In a double-blind, placebo-controlled, randomised trial, each subject consumed two capsules per d of either a placebo or a LPR formulation (1.6 × 10(8) colony-forming units of LPR/capsule with oligofructose and inulin). Each group was submitted to moderate energy restriction for the first 12 weeks followed by 12 weeks of weight maintenance. Body weight and composition were measured at baseline, at week 12 and at week 24. The intention-to-treat analysis showed that after the first 12 weeks and after 24 weeks, mean weight loss was not significantly different between the LPR and placebo groups when all the subjects were considered. However, a significant treatment × sex interaction was observed. The mean weight loss in women in the LPR group was significantly higher than that in women in the placebo group (P = 0.02) after the first 12 weeks, whereas it was similar in men in the two groups (P= 0.53). Women in the LPR group continued to lose body weight and fat mass during the weight-maintenance period, whereas opposite changes were observed in the placebo group. Changes in body weight and fat mass during the weight-maintenance period were similar in men in both the groups. LPR-induced weight loss in women was associated not only with significant reductions in fat mass and circulating leptin concentrations but also with the relative abundance of bacteria of the Lachnospiraceae family in faeces. The present study shows that the Lactobacillus rhamnosus CGMCC1.3724 formulation helps obese women to achieve sustainable weight loss.

Neonatal rat hypoxia–ischemia: Effect of the anti‐oxidant mitoquinol, and S‐PBN (2008)

Solely targeting mitochondrial oxidants with mitoQ, or extracellular oxidants with S-PBN, is not protective for striatal medium-spiny neurons after perinatal hypoxia-ischemia.
Planar concentrators near the étendue limit (2005)

Recently proposed aplanatic imaging designs are integrally combined with nonimaging flux boosters to produce an ultracompact planar glass-filled concentrator that performs near the étendue limit. Such optical devices are attractive for high-efficiency multijunction photovoltaics at high flux, with realistic power generation of 1 W from a 1 mm2 cell. When deployed in reverse, our designs provide collimation even for high-numerical-aperture light sources.
DESIGN AND MICROCONTROLLER IMPLEMENTATION OF A THREE PHASE SCR POWER CONVERTER (1996)

A single processor controls a three phase silicon controlled rectifier (SCR) power converter. An inexpensive, dual optoisolator interface to the power line provides noise rejection and an improved measure of the zero crossing. A dynamic digital phase-locked loop (PLL) algorithm implemented in an Intel 87C196KD-20 processor achieves frequency tracking, dynamically changing characteristics for improved performance. Dynamically modifying the PLL characteristics permits independent capture and locked dynamics. A feedforward method provides command tracking for improved response without loss of performance. This three-component design (processor, optoisolator, and SCR gate drivers) represents a minimal implementation with potential for closed loop voltage and current control. High speed input and output resources included on the 87C196KD processor make an efficient single-device implementation possible. The processor is less than 1% utilized allowing for additional functions to be added in the future. This system operates on both 50 Hz and 60 Hz power systems without modification or loss of performance.
Where the bugs are (2004)

The ability to predict which files in a large software system are most likely to contain the largest numbers of faults in the next release can be a very valuable asset. To accomplish this, a negative binomial regression model using information from previous releases has been developed and used to predict the numbers of faults for a large industrial inventory system. The files of each release were sorted in descending order based on the predicted number of faults and then the first 20% of the files were selected. This was done for each of fifteen consecutive releases, representing more than four years of field usage. The predictions were extremely accurate, correctly selecting files that contained between 71% and 92% of the faults, with the overall average being 83%. In addition, the same model was used on data for the same system's releases, but with all fault data prior to integration testing removed. The prediction was again very accurate, ranging from 71% to 93%, with the average being 84%. Predictions were made for a second system, and again the first 20% of files accounted for 83% of the identified faults. Finally, a highly simplified predictor was considered which correctly predicted 73% and 74% of the faults for the two systems.

Solution‐processed Cu(In,Ga)(S,Se)<sub>2</sub> absorber yielding a 15.2% efficient solar cell (2012)

ABSTRACT The remarkable potential for inexpensive upscale of solution processing technologies is expected to enable chalcogenide‐based photovoltaic systems to become more widely adopted to meet worldwide energy needs. Here, we report a thin‐film solar cell with solution‐processed Cu(In,Ga)(S,Se) 2 (CIGS) absorber. The power conversion efficiency of 15.2% is the highest published value for a pure solution deposition technique for any photovoltaic absorber material and is on par with the best nonvacuum‐processed CIGS devices. We compare the performance of our cell with a world champion vacuum‐deposited CIGS cell and perform detailed characterization, such as biased quantum efficiency, temperature‐dependent electrical measurement, time‐resolved photoluminescence, and capacitance spectroscopy.

Context-Derived Pseudonyms for Protection of Privacy in Transport Middleware and Applications (2007)

This paper outlines why context-aware transport applications necessarily record information about people and describes how we can use anonymity techniques to minimise the resulting invasion of privacy. In particular we: (i) describe how to generate unlinkable personal pseudonyms; (ii) describe a method of creating group pseudonyms (an opaque pseudonym representing several individuals); and (iii) describe how to store these pseudonyms safely in a database. We go on to present two sample transport applications which utilise our technique and suggest areas for future work
Hyperthermic Isolated Limb Perfusion with TNF <i>α</i> and Cisplatin in theTreatment of Osteosarcoma of the Extremities: A Feasibility Study inHealthy Dogs (1999)

Purpose. The feasibility of hyperthermic isolated limb perfusion (HILP) with tumor necrosis factor-alpha (TNFalpha ) and cisplatin for the management of osteosarcoma was studied in the canine model.Methods. During seven perfusions in six healthy mongrel dogs (weight 32+/-2 kg) technical aspects of HILP under mild hyperthermia (39- 40) were studied. In five experiments HILP was performed with TNFalpha alone (0.5 mg/l extremity volume), and in two experiments TNFalpha was combined with cisplatin (25 mg/l extremity volume). During the perfusions physiological parameters were monitored and TNFalpha and total cisplatin concentrations were determined.Results. Perfusion conditions (pH, PCO(2) , PO(2), flow and pressure) remained within physiological ranges.Three dogs died within 24 h despite a sublethal systemic concentration of TNFalpha that leaked from the perfusion circuit. Three dogs were terminated; one dog after the second experiment in accordance with Dutch ethical rules; one dog showed an invagination of the small bowel resulting in an ileus; one dog because of necrosis of the perfused limb.Conclusions. This feasibility study in healthy dogs demonstrated that HILP with TNFalpha and cisplatin was associated with a high mortality rate and does not allow us to treat dogs with spontaneous osteosarcoma with TNFalpha and cisplatin HILP. Therefore, an alternative model should be used in the search for the ideal combination of perfusion agents for limb sparing treatment in human osteosarcoma.
Analog Computer for the Roots of Algebraic Equations (1953)

An electronic analog machine for computing the roots of algebraic equations of degrees through the eighth is described. The coefficients of the equation may be complex. The roots are indicated as points in the complex number plane light points on the screen of a cathode-ray tube. Once per second the roots are displayed, and when some of the coefficients are varied the corresponding curves described by the roots are made visible by the persistence of light emission from the screen. An accurate determination of the roots is obtained by means of a comparison-root which can be moved all over the number plane and thus be brought to coincide with a root. The comparison-root is displayed by a scanning system, which also controls the positions of the roots, and so it is possible to obtain an accurate reading not influenced by distortion in the cathode-ray tube. By means of a normalizing device, the voltage level in the machine is kept high throughout the computation, and so all the roots are determined with about the same percental accuracy. The modulus of an error will normally be of the magnitude of 1 per cent of the corresponding root-modulus.
Matrix metalloproteinase 8 (neutrophil collagenase) in the pathogenesis of abdominal aortic aneurysm (2005)

The high concentration of MMP-8 in aortic aneurysms represents a potent pathway for collagen degradation, and hence aneurysm formation and expansion.
Treatment of endometriosis with a long-acting gonadotropin-releasing hormone agonist. (1987)

Sixteen women with endometriosis were treated with daily subcutaneous injections of a potent agonist of gonadotropin-releasing hormone (GnRH) for six months. Ovarian estrogen secretion was reduced to castrate levels during most of the course of treatment. Blinded evaluation of laparoscopic photographs confirmed marked suppression of visually apparent disease, but biopsy specimens showed occult, inactive endometriosis in most cases. Marked pain relief was noted by all patients. As a result of this "medical oophorectomy," the women experienced severe hot flashes, and many had insomnia and emotional disturbances. Vaginal cytology showed menopausal changes but related symptoms were generally mild. Calcium excretion rose to menopausal levels. High-density lipoprotein and total cholesterol remained unchanged. These results indicate that GnRH agonist administration has impressive effects on endometriotic implants, and these actions may be enhanced with longer therapy. Further development of this new form of therapy should involve either use of lesser degrees of ovarian suppression or adjunctive therapy to counter the side effects of "medical oophorectomy."
High-Density Full-CMOS SRAM Cell Technology with a Deep Sub-Micron Spacing between nMOS and pMOSFET (Special Section on High Speed and High Density Multi Functional LSI Memories) (1994)

1. A cross-sectional study (protocol A) was performed in 19 rats with cirrhosis, induced by carbon tetrachloride (CCl4), and ascites and in 10 control animals to assess renal prostaglandin (PG) excretion in experimental cirrhosis. In an additional group of animals, including nine rats chronically exposed to CCl4 (CCl4 rats) and six control rats, a longitudinal study (protocol B) was performed to investigate the temporal relationship between changes in renal PG excretion, the renin--aldosterone system and renal function. 2. Urinary PG excretion was assessed by specific radioimmunoassay of PGE2, PGF2 alpha, 6-keto-PGF1 alpha and thromboxane (TX) B2 after extraction with octadecyl silica cartridges and h.p.l.c. purification. Recoveries for each prostanoid (61 +/- 8% for PGE2, 64 +/- 12% for PGF2 alpha, 65 +/- 11% for 6-keto-PGF1 alpha and 66 +/- 17% for TXB2) were determined in every sample by adding tritiated standards, and the final values were corrected according to the individual recoveries. 3. Cirrhotic rats with ascites in protocol A showed a significantly higher plasma renin and aldosterone concentrations and urinary excretion of 6-keto-PGF1 alpha and TXB2 than did control animals. Urinary excretion of PGE2 and PGF2 alpha, however, was significantly reduced in cirrhotic animals as compared with controls. 4. In CCl4 rats included in protocol B, there was a close chronological relationship between the activation of the renin-aldosterone system, as estimated by urinary aldosterone excretion, the onset of sodium retention and the increase in urinary excretion of 6-keto-PGF1 alpha and TXB2. The urinary excretion of PGE2 and PGF2 alpha in CCl4 rats was reduced throughout the study.(ABSTRACT TRUNCATED AT 250 WORDS)
A functional magnetic resonance imaging investigation of episodic memory after traumatic brain injury (2011)

Traumatic brain injury often negatively impacts episodic memory; however, studies of the neural substrates of this impairment have been limited. In this study, both encoding and recognition of visually presented stimuli were examined with functional magnetic resonance imaging. Twelve adults with chronic complicated mild, moderate, and severe injuries were compared with a matched group of 12 controls. Behavioral task performance did not differentiate the groups. During neuroimaging, however, the group of individuals with traumatic brain injury exhibited increased activation, as well as increased bilaterality and dispersion as compared to controls. Findings are discussed in terms of increased resource recruitment.
Structured illumination microscopy using photoswitchable fluorescent proteins (2008)

In fluorescence microscopy the lateral resolution is limited to about 200 nm because of diffraction. Resolution improvement by a factor of two can be achieved using structured illumination, where a ine grating is projected onto the sample, and the final image is reconstructed from a set of images taken at different grating positions. Further resolution improvement can be achieved by saturating the transitions involved in fluorescence emission. Recently discovered photoswitchable proteins undergo transitions that are saturable at low illumination intensity. Combining this concept with structured illumination, theoretically unlimited resolution can be achieved, where the smallest resolvable distance will be determined by signal-to-noise ratio. This work focuses on the use of the photoswitchable protein Dronpa with structured illumination to achieve nanometre scale resolution in fixed cells.
Fabrication of electrode–electrolyte interfaces in all-solid-state rechargeable lithium batteries by using a supercooled liquid state of the glassy electrolytes (2010)

The softening behavior of a 80Li2S·20P2S5 (mol%) glass electrolyte was investigated and a favorable electrode–electrolyte interface was fabricated by sticking the supercooled liquid state of the 80Li2S·20P2S5 electrolyte on active material particles. A dense pellet of the glass electrolyte without an obvious grain boundary or any voids was prepared by softening the 80Li2S·20P2S5 glass by means of a hot press. The electrical conductivity of the pellet was 8.8 × 10−4 S cm−1 at room temperature. Sticking the solid electrolyte on the Li4Ti5O12 active material particles increased the contact area at the electrode–electrolyte interface and the utilization of the active material was increased in the all-solid-state cells. However, LiCoO2 reacted with the solid electrolyte during the hot press and the electrochemical performance of the cells using hot-pressed LiCoO2 with the glass electrolyte degraded. LiNbO3 coating suppressed the reaction of LiCoO2 with the solid electrolyte. The all-solid-state full-cell Li4Ti5O12/80Li2S·20P2S5 glass/LiNbO3-coated LiCoO2 prepared by hot press showed a larger reversible capacity of 120 mAh g−1 at 0.064 mA cm−2 compared with the full-cell prepared by cold press. The softening of the 80Li2S·20P2S5 glass electrolyte is an effective way for increasing the contact area between the active materials and solid electrolyte.
Pathogenesis of pelvic inflammatory disease. (1993)

Our current concept of the pathogenesis of pelvic inflammatory disease (PID) is a synthe- sis of information from many sources. The main part is indirectly derived from epidemiological, clinical, and laboratory observations, as well as from deductions by analogy from findings in experimental systems. Docu- mented facts are scarce, fragmentary, and in part contradictory.
