Automatic detection of speaker attributes based on utterance text (2011)

In this paper, we present models for detecting various attributes of a speaker based on uttered text alone. These attributes include whether the speaker is speaking his/her native language, the speaker’s age and gender, and the regional information reported by the speakers. We explore various lexical features as well as features inspired by Linguistic Inquiry and Word Count and Dictionary of Affect in Language. Overall, results suggest that when audio data is not available, by exploring effective feature sets only from uttered text and system combinations of multiple classification algorithms, we can build high quality statistical models to detect these attributes of speakers, comparable to systems that can exploit the audio data.
Transduction of donor hematopoietic stem-progenitor cells with Fas ligand enhanced short-term engraftment in a murine model of allogeneic bone marrow transplantation (2002)

Fas-mediated apoptosis is a major physiologic mechanism by which activated T cells are eliminated after antigen-stimulated clonal expansion generates a specific cellular immune response. Because activated T cells are the major effectors of allograft rejection, we hypothesized that genetically modifying allogeneic bone marrow (BM) cells prior to transplantation could provide some protection from host T-cell attack, thus enhancing donor cell engraftment in bone marrow transplantation (BMT). We undertook studies to determine the outcome of lentiviral vector-mediated transduction of Fas ligand (FasL) into lineage antigen-negative (lin(-)) mouse BM cells (lin(-) BMs), in an allogeneic BMT model. FasL-modified lin(-) BMs killed Fas-expressing T cells in vitro. Mice that received transplants of allogeneic FasL(+) lin(-) BMs had enhanced short-term engraftment, after nonmyeloablative conditioning, as compared to controls. We observed no major hepatic toxicity or hematopoietic or immune impairment in recipient mice at these time points. These results suggest potential therapeutic approaches by manipulating lymphohematopoietic stem-progenitor cells to express FasL or other immune-modulating genes in the context of BMT.
Supratentorial—infraoccipital approach for posteromedial temporal lobe lesions (1995)

The use of the supratentorial-infraoccipital approach is reported in seven patients with posteromedial temporal lobe lesions. No patient had permanent morbidity. Gross total resection of three low-grade gliomas and two gangliogliomas was achieved in five patients; one patient had subtotal resection of a low-grade glioma with adjacent gliosis, and one was initially thought to have a glioma but proved to have encephalomalacia on final pathological analysis. The patients ranged in age from 5 to 34 years. All seven patients presented with seizures, and four had uncontrolled seizures preoperatively. Six have been seizure-free since surgery (mean follow-up period 15 months), and one is well controlled on anticonvulsant medication. An anatomical study was performed to delineate the microsurgical anatomy relevant to operating on the medial temporal lobe through this posterior approach. A viewing wand intraoperative navigational system was utilized with this approach and proved helpful in gaining access as far anterior as the uncus through this occipital craniotomy. This approach is favorable in selected patients with posterior, medial, temporal lobe tumors because resection of otherwise difficult lesions may be accomplished without sacrificing lateral temporal lobe cortex or transecting the optic radiations.
Learning Bayesian networks from incomplete data (1997)

Much of the current research in learning Bayesian Networks fails to effectively deal with missing data. Most of the methods assume that the data is complete, or make the data complete using fairly ad-hoc methods; other methods do deal with missing data but learn only the conditional probabilities, assuming that the structure is known. We present a principled approach to learn both the Bayesian network structure as well as the conditional probabilities from incomplete data. The proposed algorithm is an iterative method that uses a combination of Expectation-Maximization (EM) and Imputation techniques. Results are presented on synthetic data sets which show that the performance of the new algorithm is much better than ad-hoc methods for handling missing data.
Magnetoelectric effect for novel microwave device applications (2008)

In a normally magnetized thin-film ferrite disk with magnetic-dipolar modes, one can observe magneto-electric oscillations. Such magnetoelectric properties of an electrically small sample can be considered as very attractive phenomena in microwaves. In this paper we discuss the question on novel microwave device applications based on ferrite magnetoelectric particles.
Monocular Depth Estimation: A Survey (2019)

Monocular depth estimation is often described as an ill-posed and inherently ambiguous problem. Estimating depth from 2D images is a crucial step in scene reconstruction, 3Dobject recognition, segmentation, and detection. The problem can be framed as: given a single RGB image as input, predict a dense depth map for each pixel. This problem is worsened by the fact that most scenes have large texture and structural variations, object occlusions, and rich geometric detailing. All these factors contribute to difficulty in accurate depth estimation. In this paper, we review five papers that attempt to solve the depth estimation problem with various techniques including supervised, weakly-supervised, and unsupervised learning techniques. We then compare these papers and understand the improvements made over one another. Finally, we explore potential improvements that can aid to better solve this problem.

Compile/run-time support for thread migration (2002)

Describes a generic mechanism to migrate threads in heterogeneous distributed environments. To maintain high portability and flexibility, thread migration is implemented at the language level. At compile-time, a pre-processor scans the C and C++ programs to build the thread state, detects possible thread migration points and transforms the source code accordingly. Run-time support helps to migrate the threads physically. Since the physical thread state is transformed into a logical form, and pointers and dynamically-allocated memory in a heap are supported, the proposed solution places no restriction on thread types and migration-enabled systems. We implemented this approach in Strings, a multithreaded-software distributed shared memory system. Some microbenchmarks and performance measurements on the SPLASH-2 suite are reported.
Breaking through for breakthroughs: the problem of normal science in rare disease research (2014)

Scientific breakthroughs themselves often do not carry the force needed for acceptance or adoption. By their very nature, scientific breakthroughs challenge the status quo or Normal Science. Therefore, those who forge scientific breakthroughs will have to break through Normal Science if their discoveries are to be adopted. Needing to break through Normal Science may not come as a surprise to people educated and training in the biosciences, but it will to many people who come to rare diseases from outside the biosciences and through necessity. In this commentary, I describe the basis and components of Normal Science, and how it can impede the progress of scientific breakthroughs. I refer to Thomas Kuhn’s concept of the ‘structure of scientific revolutions’ as an explanatory model, and I use three case studies to illustrate it. I also provide ideas on measures that can be taken to help people in rare disease research recognize and prepare for the resistance Normal Science may pose for their breakthroughs.
<title>DSP acceleration using cache logic FPGAs</title> (1995)

Stand-alone digital signal processors (DSPs) support many on-chip functions and are highly optimized for the demands of high-speed computing. The problem associated with this functional optimization is that the increase in performance comes at the expense of flexibility. To make the DSP general purpose enough for a wide variety of applications, a custom ASIC must be used to achieve the desired performance. DSPs and ASICs are not able to easily adapt on-the-fly to different algorithms. Even DSPs that can do this don't match the high level of optimization provided by an ASIC. Recent developments in FPGA design tools enable system designers to develop in-system reconfigurable adaptive DSP hardware. Designed to exploit register rich, dynamically recongigurable field programmable gate arrays, high speed custom DSP functions can be created and implemented, resulting in significantly improved performance for compute-intensive applications, including graphics and image processing, telecommunications, networking and instrumentation.
Selection and Enrichment of Denitrifying Phosphorus Accumulating Organisms in Activated Sludge (2009)

Activated sludge from a local non-biological nutrient removal wastewater treatment plant was inoculated into a sequencing batch reactor (SBR) to investigate the techniques and required conditions for the selection and enrichment of denitrifying phosphorus accumulating organisms (DNPAOs). The SBR was operated under varying anaerobic, anoxic and aerobic conditions for 3 mon. In this study, it was demonstrated that Enhanced biological phosphorus removal (EBPR) was established rapidly by the application of the anaerobic/aerobic (A/O) process and the selection of DNPAOs was achieved by introducing an anoxic phase. With an extension of the anoxic period and increasing nitrate dosage, the community shift between aerobic phosphorus accumulating organisms (PAOs) and DNPAOs was observed. An approximate 60% DNPAO fraction was obtained from this experiment.
Humidity-dependent thermoelectric properties of poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (2016)

Thermoelectric properties of poly(3,4-ethylenedioxythiophene) doped by different amounts of poly(styrene sulfonate) (PSS) were tested under various humidity conditions. The thermoelectric power factor was found to increase with humidity, with a larger increase observed for samples with less PSS content. For these samples with low PSS content, the Seebeck coefficient and electrical conductivity were observed to simultaneously increase as humidity was increased. Thermal conductivity was observed to increase with increasing humidity for samples with low PSS content and decrease for samples with high PSS content. Measurements on thick films soaked by various polar solvents likewise showed an enhancement in power factor.
Evidence for Gravity as a Cue for Absolute Size and Distance (1994)

The constant force of gravity constrains the motion of objects in natural environments. In principle, gravity could provide valuable scaling information about size and distance of unfamiliar objects. We supply empirical evidence that observers use some of the information provided by gravity to scale objects. However, scaling judgments based on retinal size and event duration alone are nearly as accurate as those made with gravitational acceleration information.
Visual detection of knives in security applications using Active Appearance Models (2013)

In this paper, a novel application of Active Appearance Models to detecting knives in images is presented. In contrast to its popular applications in face segmentation and medical image analysis, we not only use this computer vision algorithm to locate an object that is known to exist in an analysed image, but–using an interest point typical of knives–also try to identify whether or not a knife exists in the image in question. We propose an entire detection scheme and examine its performance on a sample test set. The work presented in this paper aims to create a robust visual knife-detector to be used in security applications.

Automated tracking and quantification of angiogenic vessel formation in 3D microfluidic devices (2017)

Angiogenesis, the growth of new blood vessels from pre-existing vessels, is a critical step in cancer invasion. Better understanding of the angiogenic mechanisms is required to develop effective antiangiogenic therapies for cancer treatment. We culture angiogenic vessels in 3D microfluidic devices under different Sphingosin-1-phosphate (S1P) conditions and develop an automated vessel formation tracking system (AVFTS) to track the angiogenic vessel formation and extract quantitative vessel information from the experimental time-lapse phase contrast images. The proposed AVFTS first preprocesses the experimental images, then applies a distance transform and an augmented fast marching method in skeletonization, and finally implements the Hungarian method in branch tracking. When applying the AVFTS to our experimental data, we achieve 97.3% precision and 93.9% recall by comparing with the ground truth obtained from manual tracking by visual inspection. This system enables biologists to quantitatively compare the influence of different growth factors. Specifically, we conclude that the positive S1P gradient increases cell migration and vessel elongation, leading to a higher probability for branching to occur. The AVFTS is also applicable to distinguish tip and stalk cells by considering the relative cell locations in a branch. Moreover, we generate a novel type of cell lineage plot, which not only provides cell migration and proliferation histories but also demonstrates cell phenotypic changes and branch information.
Improved Response Time and Bend Transition Time of OCB-LCDs Used at Low Temperature (2008)

To ensure safety, display devices that are used in automobiles need motion picture visibility at any situation. However, low temperatures cause conventional LCDs to respond more slowly, and this leads to motion blur. To eliminate this blurring, we have newly developed a high-performance OCB-LCD that responds quickly at low temperatures. We have speeded up the response time by using of an LC material that has a low rotational viscosity and by improving the bend transition. The new OCB-LCD has both a very fast response time and bend transition. The response time is a third that of the conventional OCB-LCD at -20°C, and does not require the present optical design to be changed. The bend transition time is about 1 second at -30°C. This speed is highly suitable for display devices used in automobiles.
Germination of Coffee Seeds (Coffea arabicaL. cv. Mundo Novo) (1976)

The life-span of coffee seeds is extended when seeds are stored with high moisture content. Germination in darkness is always higher than in the light. Exogenous gibberellic acid and abscisic acid inhibit germination while kinetin reverses this inhibitory effect. Low levels of endogenous gibberellin- and abscisic acid-like and high levels of cytokinin-like substances favour germination while the opposite combination of regulators delays germination.

Eficacia de los paneles evaporativos en la refrigeración de invernaderos (2007)

Neurological complications are significantly more common in patients with previous by-pass surgery. Considering the risk for neurological complications the risk-benefit ratio may be higher when compared with patients without previous by-pass surgery.
The Evaluation of miR-21 Level in Lung Tissue and Plasma of Nsclc Patients (2017)

Background: Lung cancer is one of the most common malignant tumors with poor survival, which is usually diagnosed at advanced stages. In recent years, increasing evidence has revealed that circulating miRNAs exhibit great potential in screening and early detection of various types of cancers including lung cancer. miR-21 is one of the most highly expressed members of the microRNA family in many human cancer types. Methods: The authors analyzed miR-21 expression in matched tumor and normal tissues and plasma in 17 patients affected with non-small cell lung cancer. Samples were collected from the NSCLC patients before surgery, radiotherapy or chemotherapy. Expression levels of tissue miR-21 were assessed, using TaqMan RT-PCR assay. Expression levels of plasma miR-21 were assessed, using LNA™ RT microRNA PCR primer set and SYBR green qRT-PCR assay. Results: miR-21 expression was higher in 9 out of 17 patients’ plasma samples. No change in miR-21 expression was observed in 8 plasma samples. In lung tissues, ten patients showed up-regulation of miR-21 and six patients were down-regulated. One patient had no change in miR-21 expression level in tissue samples. The expression level of mir-21 in tissue and plasma was concordant in 6 patients. Conclusion: It seems that the level of miR-21 in plasma samples of NSCLC patients as a marker for screening needs more investigation.
Electroluminescence color tuning by dye doping in organic light-emitting diodes (1998)

Doping a small amount of a fluorescent dye into an organic light-emitting diodes (OLEDs) can lead to significant changes in the color of luminescence and an improvement in the device properties (e.g,, quantum efficiency, lifetime, etc.). The process of energy transfer from the OLED material to the dye in these devices may involve several different processes, including carrier trapping as well as Forster and Dexter energy transfer reactions. The important parameters for each of these processes are discussed. The color purity and chromaticities of a wide range of different dye-doped OLED's are reviewed.
Syntheses and Crystal Structures of the New Zinc Phosphonates Zn(O3PCH2P(O)(R)(C6H5))·xH2O, Based on Mixed Phosphonic Acid−Phosphine Oxide Building Blocks (1997)

The two new zinc(II) phosphonates Zn(O(3)PCH(2)P(O)(C(6)H(5))(2)) (monoclinic P2(1)/c (No. 14), a = 9.961(2) Å, b = 5.838(1) Å, c = 24.608(5) Å, beta = 101.48(3) degrees, Z = 4) and Zn(O(3)PCH(2)P(O)(CH(3))(C(6)H(5))).0.67H(2)O (monoclinic P2(1)/c (No. 14), a = 15.879(5) Å, b = 7.383(2) Å, c = 10.475(3) Å, beta = 105.01(5) degrees, Z = 4) were prepared by reaction of zinc nitrate, (R)(C(6)H(5))P(O)CH(2)PO(3)H(2) [R = C(6)H(5), CH(3)], and sodium hydroxide in water in an autoclave. For the first compound, a unidimensional arrangement is observed, while for the second, a layered structure is obtained, in relation to the size of the substituents present on the phosphine oxide moiety.
Prognostic Significance of Basal-Like Phenotype and Fascin Expression in Node-Negative Invasive Breast Carcinomas (2006)

Basal-like tumors had a tendency towards visceral metastasis and their prognosis was dependent on the use of postoperative chemotherapy. Although fascin expression was associated with the basal-like phenotype, it was not associated with their metastatic behavior. Fascin expression is frequent in BRCA1-associated tumors.
Interleukin-18 expression by alveolar epithelial cells type II in tuberculosis and sarcoidosis (2006)

The aims of the present study were to characterize the localization of interleukin-18 (IL-18) expression in lung tissue specimens from patients with pulmonary tuberculosis, sarcoidosis and controls, and to determine whether human alveolar epithelial cells type II (AEC-II) are able to generate IL-18 in primary culture. IL-18 was determined using semiquantitative reverse-transcription-PCR and localized in lungs using in situ hybridization. IL-18 protein levels were determined using the enzyme-linked immunosorbent assay and western blot analysis. Alveolar epithelial cells type II (AEC-II) were stimulated in vitro by proinflammatory cytokines, lipopolysaccharides, and whole cell lysate from Mycobacterium tuberculosis. IL-18 mRNA expression was significantly increased in the lungs affected by tuberculosis and sarcoidosis. In situ hybridization revealed different sites of expression in tuberculosis and sarcoidosis lungs, with AEC-II as one major source of IL-18 in the alveolar compartment. Basal IL-18 expression could be detected in normal AEC-II. Whole cell lysate from M. tuberculosis, but not lipopolysaccharide, led to a strong increase of IL-18 mRNA accumulation in AEC-II. Resting AEC-II secreted only small amounts of IL-18, but intracellular IL-18 protein levels increased in a time-dependent manner during culture. Proinflammatory cytokines tumour necrosis factor-alpha, IL-1beta, and interferon-gamma altered IL-18 mRNA expression and mature protein secretion of human AEC-II. These findings indicate a possible role for AEC-II and AEC-II-derived IL-18 in pathomechanisms of granulomatous lung diseases.
Rücktitelbild: Influence of Intracrystalline Ionic Strength in MFI Zeolites on Aqueous Phase Dehydration of Methylcyclohexanols (Angew. Chem. 47/2021) (2021)

Sekundäre Alkohole , die entweder einem E1- oder einem E2-Eliminierungsweg folgen, werden in der Zuschrift von Eszter Baráth, Johannes A. Lercher et al. auf S. 25010 untersucht. Es ist bekannt, dass Wasser in den Zeolithkanälen Cluster bildet, aber sein Einfluss auf den intrinsischen Mechanismus der Dehydratisierung muss noch grundlegend verstanden werden. Es wurde festgestellt, dass die Vulkanform und die Position des Maximums bei der Dehydratisierung von Methylcyclohexanolen in wässriger Phase über verschiedenen MFI-Zeolithen eine Folge der intrakristallinen Ionenstärke und einer räumlichen Einschränkung ist.
