Fuzzy logic based symbolic grounding for best grasp pose for homecare robotics (2012)

Symbolic grounding in unstructured environments remains an important challenge in robotics [7]. Homecare robots are often required to be instructed by their human users intuitively, which means the robots are expected to take highlevel commands and execute corresponding tasks in a domestic environment. High-level commands are represented with symbolic terms such as “near” and “close” and, on the other hand, robots are controlled based on trajectories. The robots need to translate the symbolic terms to trajectories. In addition, domestic environment is unstructured where the same objects can be placed in different places over the time. This increases the difficulties in symbolic grounding. This paper presents a fuzzy logic based approach to symbolic grounding. In this approach, grounded concepts are modelled as fuzzy sets and the existing knowledge is used to deduce grounded values given real-time sensory inputs. Experiments results show that this approach works well in unstructured environment.

Two newly synthesized electrochromic polymers were utilized to prepare black films, which exhibited moderate optical contrast and robust stability.
The Mannich Base NC1153 Promotes Long-Term Allograft Survival and Spares the Recipient from Multiple Toxicities (2005)

JAK3 is a cytoplasmic tyrosine kinase with limited tissue expression but is readily found in activated T cells. Patients lacking JAK3 are immune compromised, suggesting that JAK3 represents a therapeutic target for immunosuppression. Herein, we show that a Mannich base, NC1153, blocked IL-2-induced activation of JAK3 and its downstream substrates STAT5a/b more effectively than activation of the closely related prolactin-induced JAK2 or TNF-alpha-driven NF-kappaB. In addition, NC1153 failed to inhibit several other enzymes, including growth factor receptor tyrosine kinases, Src family members, and serine/threonine protein kinases. Although NC1153 inhibited proliferation of normal human T cells challenged with IL-2, IL-4, or IL-7, it did not block T cells void of JAK3. In vivo, a 14-day oral therapy with NC1153 significantly extended survival of MHC/non-MHC mismatched rat kidney allografts, whereas a 90-day therapy induced transplantation tolerance (>200 days). Although NC1153 acted synergistically with cyclosporin A (CsA) to prolong allograft survival, it was not nephrotoxic, myelotoxic, or lipotoxic and did not increase CsA-induced nephrotoxicity. In contrast to CsA, NC1153 was not metabolized by cytochrome P450 3A4. Thus, NC1153 prolongs allograft survival without several toxic effects associated with current immunosuppressive drugs.
Mutation of lysine 405 to serine in the parvovirus H-1 NS1 abolishes its functions for viral DNA replication, late promoter trans activation, and cytotoxicity (1990)

A consensus sequence in parvovirus nonstructural protein NS1 has been predicted to be an ATP-binding domain associated with an ATPase and a DNA helicase activity. To investigate the function of NS1 in viral gene expression, a site-directed mutagenesis converting NS1 lysine 405 to serine in parvovirus H-1 was carried out by the polymerase chain reaction. As shown previously, a parvovirus genome containing a deleted NS1 gene was excised from a bacterial plasmid and replicated when a wild-type NS1 gene was provided in trans but failed to be excised and replicate when the mutant NS1 gene was supplied. Interestingly, the serine 405 mutation totally lost the activity of trans activation on the virus late promoter (P38) in a chloramphenicol acetyltransferase (CAT) assay and it lost evidence for cytotoxicity in two tumor cell lines (HeLa Gey and NB324K). The serine 405 NS1 protein was translocated normally to the nucleus. These results suggest that the NS1 lysine 405 of H-1 in its putative purine nucleotide-binding site is essential for viral DNA replication and that this domain may be involved in the regulation of the P38 promoter by an unknown mechanism. The loss of NS1 cytotoxicity on tumor cells suggests that NS1 expression is the major cause of cell killing by parvoviruses, which may facilitate further study of the mechanism of oncosuppression by parvoviruses.
Fourier-domain biophotoacoustic subsurface depth selective amplitude and phase imaging of turbid phantoms and biological tissue (2006)

A novel photothermoacoustic imaging modality utilizing a frequency-swept (chirped) intensity-modulated laser source and coherent frequency domain signal processing ("biophotoacoustics") was introduced for noninvasive imaging of biological tissues. The developed frequency-domain imaging system takes advantage of linear frequency modulation waveforms to relate depth of tissue chromophores to the frequency spectrum of the detected acoustic response and of a narrow signal detection bandwidth to improve signal-to-noise ratio (SNR). Application of frequency-domain photothermoacoustic (FD-PTA) imaging was demonstrated using turbid phantoms and ex-vivo specimens of chicken breast with embedded absorbing inclusions simulating tumors.
Selective extraction and quantitative analysis of non‐starch and starch lipids from wheat flour (1975)

Abstract Wheat flour non‐starch lipids (lipids not bound to starch) were quantitatively extracted with water‐saturated n‐butanol (WSB), benzene‐ethanol‐water (10:10:1, by vol.) or ethanol‐diethyl ether‐water (2:2:1, by vol.) in 10min at 20 °C. Starch lipids (lipids bound to starch) were subsequently extracted with WSB at 90–100 °C. Carotenoid pigments were quantitatively extracted with the non‐starch lipids. There was no significant hydrolysis of esterified fatty acids and no detectable autoxidation of unsaturated acids in the hot solvent extracts. Non‐starch and starch lipids from a high grade spring wheat flour and three grades of winter wheat flour were separated by thin‐layer chromatography and quantified as fatty acid methyl esters (FAME) by gas‐liquid chromatography (g.l.c.) using heptadecanoic acid (or its methyl ester) as internal standard. Total flour and starch lipids after acid hydrolysis were also converted to FAME for quantitation by g.l.c. Non‐starch lipids consisted of 59–63% non‐polar (neutral) lipids, 22–27% polar glycolipids and 13–16% phospholipids. Steryl esters, triglycerides, and all the diacyl galactosylglycerides and phosphoglycerides were present only in non‐starch lipids. Starch lipids consisted of 6–9% non‐polar (neutral) lipids (mostly free fatty acids), 3–5 % polar glycolipids and 86–91 % phospholipids (mostly lysophosphatidyl choline). Starch lipids were almost exclusively monoacyl lipids. Factors are given for converting weight of FAME into weight of original lipid for all individual lipid classes in wheat which contain O ‐acyl groups. Factors for total lipids are: total starch lipids = FAME × 1.70, total non‐starch lipids = FAME × 1.20, and total flour (non‐starch + starch) lipids = FAME × 1.32. Similar factors could be used to convert weight of lipids obtained by conventional acid hydrolysis methods into weight of unhydrolysed lipids. Phospholipid contents are given by: total starch phospholipids = P × 16.51, total non‐starch phospholipids = P × 23.90, total flour phospholipids = P × 17.91.
Analysis of T cells as potential sources of interleukin-22 in colorectal cancer (2017)

Interleukin-22 (IL-22) is a unique cytokine produced by immune cells and acting exclusively on IL-22 receptor-1 (IL-22-R1) positive epithelial cells. IL-22 plays a central role in epithelial regeneration and contributes to pathogen clearance. In contrast, the proliferation enhancing effects of IL-22 may be used by cancer cells to promote and sustain their growth. This has been shown in genetically modified mouse strains with spontaneous development of colorectal cancer. The cellular sources of IL-22 in tumor tissue are not yet fully identified. In a pilot study with tumor tissue of patients with colorectal cancer, we could identify CD3+CD4+ T cells that produce IL-22. This confirms findings of other groups published in recent years. Peripheral T cells from healthy donors only contained low frequencies of IL-22 producing CD3+CD4+ cells. Upon stimulation, IL-22 induced STAT3 phosphorylation and proliferation of human colon cancer cell lines. In one cell line, we could also show the induction of the cytokines IL-10 and VEGF. IL-22 suppressed IFN-γ- induced synthesis of the chemokine CCL22 in HT29 cells while enhancing TNF-α- induced expression of CCL22 in the same cell line. This indicates differential effects of IL-22 on IFN-γ- and TNF-α-signaling. IFN-γ as well as TNF-α led to IL-22-R1 upregulation in human colon cancer cell lines. In summary, we find evidence that in tumor tissue CD3+ CD4+ T cells produce IL-22. IL-22 acts directly on cells of colorectal cancer cell lines. It enhances their proliferation. IL-22 presumable serves as a mediator in the genesis of colorectal cancer and a potential therapeutic target.
Movement (2008)

Movement is the most powerful blocking tool. Movement is the actual transit of an actor or camera from one point on stage to another. In camera work, the camera movement has the same use and effect as actor movement between points. Movement takes place between compositions. In order to really see movement on the stage or screen, the actor, object, or camera must travel at least five feet.KeywordsCamera MovementCamera SetupDramatic ActionHead RoomCamera ShotThese keywords were added by machine and not by the authors.

A User-Friendly Web Content Management System (2008)

This study applies two open source projects, namely PHP and MySQL, to create a powerful, user-friendly Web-based system for creating, maintaining and publishing a database comprising news information in the form of text and graphical images. The proposed system is specifically designed to enable non-technical users with no knowledge of computer programming, graphic imaging tools, or markup languages such as HTML to add new material to a Website or to modify the existing contents as and when required in an intuitive and real-time fashion. As a result, a technically competent Website management team is not required, and thus the cost and flexibility of the Website management process is significantly improved.
Mitochondrial Function Reflected by the Decarboxylation of [<sup>13</sup>C]Ketoisocaproate Is Impaired in Alcoholics (1994)

Mitochondria of patients with alcoholic liver disease exhibit structural abnormalities, and mitochondria isolated from animals exposed to ethanol are functionally deficient when studied in vitro. To assess possible functional consequences of these ethanol-associated alterations in vivo, we measured mitochondrial function in alcoholics noninvasively with a breath test. A mitochondrial function, the decarboxylation of ketoisocaproate (KICA), was assessed by measuring the exhalation of 13CO2 following the administration of 1 mg/kg 2-keto[1-13C]isocaproic acid, the decarboxylation of which occurs in mitochondria. The results of the KICA breath test in 12 alcoholic subjects were compared with the results in healthy controls and patients with nonalcoholic liver disease. The peak exhalation of 13CO2 and the fraction of the administered dose decarboxylated in 120 min were both significantly lower in alcoholics than in healthy controls and patients with nonalcoholic liver disease. In alcoholics, KICA decarboxylation was impaired in the presence of normal quantitative liver function tests such as the aminopyrine breath test and galactose elimination capacity, indicating that KICA decarboxylation does not simply reflect a decreased functional hepatic mass. The enrichment of circulating KICA with [13C]KICA was similar in alcoholics and controls, indicating that a decreased bioavailability or an increased dilution of labeled KICA cannot account for the decreased exhalation of 13CO2. It is concluded that mitochondrial function as reflected by KICA decarboxylation is impaired in chronic alcoholics. The functional impairment is specific for ethanol abuse and not a reflection of decreased global hepatic function. KICA decarboxylation could thus be useful as a marker for excessive ethanol consumption.
Materials and Processes for Schottky Contacts on Silicon Carbide (2021)

Silicon carbide (4H-SiC) Schottky diodes have reached a mature level of technology and are today essential elements in many applications of power electronics. In this context, the study of Schottky barriers on 4H-SiC is of primary importance, since a deeper understanding of the metal/4H-SiC interface is the prerequisite to improving the electrical properties of these devices. To this aim, over the last three decades, many efforts have been devoted to developing the technology for 4H-SiC-based Schottky diodes. In this review paper, after a brief introduction to the fundamental properties and electrical characterization of metal/4H-SiC Schottky barriers, an overview of the best-established materials and processing for the fabrication of Schottky contacts to 4H-SiC is given. Afterwards, besides the consolidated approaches, a variety of nonconventional methods proposed in literature to control the Schottky barrier properties for specific applications is presented. Besides the possibility of gaining insight into the physical characteristics of the Schottky contact, this subject is of particular interest for the device makers, in order to develop a new class of Schottky diodes with superior characteristics.

Glutamate-Induced Brain Damage in Infant Primates (1972)

The brains of 9 infant rhesus monkeys were examined for acute cytopathology following treatment with monosodium L-glutamate (MSG) (6 infants) or NaCl (3 infants). Hypothalamie lesions identical to those described elsewhere in MSG-treated rodents were identified by light microscopy and verified with the electron microscope in each infant monkey given MSG. No cellular pathology was detected in the hypothalami of NaCl-treated controls. Infants given relatively low oral doses of MSG (1 and 2 g/kg) sustained small focal lesions confined primarily to the rostro-ventral aspect of the infundibular nucleus. Those treated with high subcutaneous doses developed lesions which spread throughout and sometimes beyond the infundibular nucleus. At all doses tested (1–4 g/kg) and by either route of administration, rapid necrosis of neurons (within 5 hours) was a striking feature of the MSG-induced reaction pattern. Blood glutamate curves from time of treatment to time of sacrifice (5 hours) suggest that the threshold for lesion formation in 1-week-old rhesus monkeys may be in the range of 20 mg%. Differences in research approach which might account for the failure of others to locate the lesions we describe are discussed as are some of the toxicological implications of our findings.
Renewable Natural Resource Management and Use without Markets (2000)

Natural resources, by their nature, are not readily bent to the status of private property. Efficient resource use is complicated by jurisdictional externalities, public goods, non-use values, and beneficiaries spatially separated from the location of resources. The task is made more challenging by ecological complexity that obscures cause (benefits) and effects (costs), and dramatic time lags between individual actions and subsequent social consequences that, together with substantial uncertainty, introduce the chance of irreversibilities. Resource economists have played a major role in the literature on externalities, the development of individual transferable quotas, non-market valuation techniques and common property management.
Electronic control system infrared heating applied to surface cooking (1988)

Resistive heating units made from materials such as molybdenum disilicide (MoSi/sub 2/) and tungsten (W) can generate short-wavelength infrared (IR) energy, which can pass through IR transmissive glass-ceramic to heat up cooking utensils. Cooktops made with IR heating units provide for smooth-top cooking surfaces that are highly efficient with fast response times. However, these materials have unique characteristics that create severe control problems. An electronic control system that solves problems such as the nonlinearity between on-time and power output, the high inrush currents, the RFI/light-flicker interference, and the complexity of controlling four heating units in a cooktop versus one heating unit is described. The IR heater control portion is combined with standard electronic functions, such as input and display, to produce a low-cost microprocessor-based control.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

This is the first time the cellular effects of LAE on bacterial cells were studied.
Experimental system of free viewpoint television (2003)

In this paper, we proposed a new realtime dynamic ray data acquisition and rendering system named the “Free Viewpoint Television” or “FTV”. With this system, the user can freely control the viewpoint position of any dynamic real-world scene in realtime. The basic idea of this system is based on the ray-space method in which an arbitrary photo-realistic view can be generated from a collection of real view images. Since the system is aimed for realtime operation, the collection of images is obtained through an array of cameras where the generation of the missing ray information can be obtained by interpolation of data between cameras. The prototype system used here includes 16 CCD cameras forming a camera array. The interpolation is based on the adaptive filtering ray-space data interpolation technique. Between each pair of cameras, up to 15 interpolated views can be generated to ensure that no aliasing occurs. The system fully operates under consumer-class hardware. The results achieved from the system are good in terms of both image quality and rendering speed.
A kinetic study of wild-type and mutant dihydrofolate reductases from Lactobacillus casei (1989)

A kinetic scheme is presented for Lactobacillus casei dihydrofolate reductase that predicts steady-state kinetic parameters. This scheme was derived from measuring association and dissociation rate constants and pre-steady-state transients by using stopped-flow fluorescence and absorbance spectroscopy. Two major features of this kinetic scheme are the following: (i) product dissociation is the rate-limiting step for steady-state turnover at low pH and follows a specific, preferred pathway in which tetrahydrofolate (H4F) dissociation occurs after NADPH replaces NADP+ in the ternary complex; (ii) the rate constant for hydride transfer from NADPH to dihydrofolate (H2F) is rapid (khyd = 430 s-1), favorable (Keq = 290), and pH dependent (pKa = 6.0), reflecting ionization of a single group. Not only is this scheme identical in form with the Escherichia coli kinetic scheme [Fierke et al. (1987) Biochemistry 26, 4085] but moreover none of the rate constants vary by more than 40-fold despite there being less than 30% amino acid homology between the two enzymes. This similarity is consistent with their overall structural congruence. The role of Trp-21 of L. casei dihydrofolate reductase in binding and catalysis was probed by amino acid substitution. Trp-21, a strictly conserved residue near both the folate and coenzyme binding sites, was replaced by leucine. Two major effects of this substitution are on (i) the rate constant for hydride transfer which decreases 100-fold, becoming the rate-limiting step in steady-state turnover, and (ii) the affinities for NADPH and NADP+ which decrease by approximately 3.5 and approximately 0.5 kcal mol-1, respectively.(ABSTRACT TRUNCATED AT 250 WORDS)
Therapeutic use of right atrial pressures early after the Fontan operation (1990)

In 334 patients undergoing the Fontan operation, the right atrial pressure was 16 +/- 36 mm Hg (mean value +/- SD) 3 h postoperatively, and was on average higher in those who died or had a takedown of the operation than in those who did not (P = 0.0001). Twenty-four hours after operation, the right atrial pressure was 18 +/- 5.5 mm Hg, was higher in those who died or had a takedown than in those who did not (P less than 0.0001); and in those who died or had takedown it was 23.5 +/- 1.66 mm Hg and higher than at 3 h postoperatively (18.7 +/- 0.52). The left atrial pressure 3 h postoperatively was 9 +/- 3.6 mm Hg, and on average was higher in the patients who died or had a Fontan takedown than in those who did not. The continuous relation between right atrial pressure and the probability of death or takedown during the first 24 postoperative hours was such as to recommend consideration of takedown whenever the right atrial pressure reaches 22 mm Hg, and when higher, the recommendation is made with greater urgency.
Traffic sign recognition with multi-scale Convolutional Networks (2011)

We apply Convolutional Networks (ConvNets) to the task of traffic sign classification as part of the GTSRB competition. ConvNets are biologically-inspired multi-stage architectures that automatically learn hierarchies of invariant features. While many popular vision approaches use hand-crafted features such as HOG or SIFT, ConvNets learn features at every level from data that are tuned to the task at hand. The traditional ConvNet architecture was modified by feeding 1 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">st</sup> stage features in addition to 2 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">nd</sup> stage features to the classifier. The system yielded the 2nd-best accuracy of 98.97% during phase I of the competition (the best entry obtained 98.98%), above the human performance of 98.81%, using 32×32 color input images. Experiments conducted after phase 1 produced a new record of 99.17% by increasing the network capacity, and by using greyscale images instead of color. Interestingly, random features still yielded competitive results (97.33%).
