Self-Supervised 3D Human Pose Estimation in Static Video Via Neural Rendering (2022)

Inferring 3D human pose from 2D images is a challenging and long-standing problem in the field of computer vision with many applications including motion capture, virtual reality, surveillance or gait analysis for sports and medicine. We present preliminary results for a method to estimate 3D pose from 2D video containing a single person and a static background without the need for any manual landmark annotations. We achieve this by formulating a simple yet effective self-supervision task: our model is required to reconstruct a random frame of a video given a frame from another timepoint and a rendered image of a transformed human shape template. Crucially for optimisation, our ray casting based rendering pipeline is fully differentiable, enabling end to end training solely based on the reconstruction task.
Significance and Removal of Manganese in Water Supplies (1960)

This article is based on data accumulated by AWWA Task Group 2680 P‐Manganese Deposition in Pipelines. Manganese is a common ingredient of impounded water and of many well waters. In public supplies, it causes such difficulties as staining of clothes and plumbing fixtures, “black” water, incrustation of mains, and interferences with the colorimetric chlorine residual test. In industrial supplies, it causes severe economic losses through discoloration of products, specks in finished goods, and reduction of pipeline carrying capacities. Chemical reactions are generally presumed to account for the greater part of the manganese in groundwater; in stored water, manganese builds up by a combination of biologic and chemical processes working simultaneously. It is difficult to obtain clear‐cut statements about the economic significance of manganese in water supplies. In spite of this, requests increase yearly for information on how to remove manganese, how much the process will cost, and what method will best suit a specific water supply. This article discusses the reporting of manganese, manganese‐reporting organisms, manganese determination, filter media, manganese stabilization, and manganese removal by the zeolite process or by oxidation.
Deformation transfer based on stretchiness ratio (2013)

Recent work for deformation transfer is almost based on the deformation gradient framework [Sumner and Popović 2004], which deforms a target mesh by transferring local affine transformation in an optimization framework. We aim to explore a coordinate-invariant quantity for deformation transfer. What we propose here is to achieve deformation by transferring stretchiness ratio between the source meshes to the target.
Cocoa Powder as Delivery Medium for Probiotic Lactobacillus Strains (2011)

Three Lactobacillus strains previously isolated from artisanal Italian cheeses and identified by species-specific PCR as L. helveticus, L. paracasei and L. rhamnosus, were evaluated for the presence of functional traits, such as acidifying activity, cell surface hydrophobicity, antibiotic resistance, survival in low pH and in presence of bile salts, in comparison with two commercially available probiotic strains (Lactobacillus acidophilus La-5 and L. rhamnosus GG). Subsequently, with the aim to develop a new non-dairy functional product, cocoa powder was used as a medium for incorporating freeze-dried cultures of each tested strain and survival at different time/temperature conditions was investigated. The results obtained demonstrated that artisanal dairy products are interesting sources of new probiotic strains; in particular, the dairy origin strain L. rhamnosus showed a good probiotic performance and the highest level of survival during storage. Finally, we showed that cocoa powder represents a good delivery medium for lactobacilli: it could be considered a novel functional food exhibiting high antioxidant power and presenting probiotic potential.
Virtual endoscopy of the upper airway − a diagnostic tool (2000)

Abstract A 78-year-old man underwent open heart surgery complicated by prolonged intubation and requiring a tracheotomy. Three months after decannulation he presented with progressive difficulty in breathing due to laryngotracheal stenosis. Laryngotracheal reconstruction with insertion of a T-tube were performed. At surgery, thyroid goitre was found and the trachea was slightly deviated to the left. Six months after surgery, the patient complained about progressive difficulty in breathing while recumbent and could not manage with a plugged T-tube. Fiberoptic laryngoscopy did not reveal any significant pathology. It was not possible to pass the scope through the glottis. Three-dimensional spiral computed tomography (CT) including virtual endoscopy (VE) was then performed. A large multinodular appearing goitre was found. VE demonstrated severe deviation of the tracheal segment containing the T-tube from the more superior airway. A shelf-like soft tissue was hanging over the upper margin of the T-tube, leaving only a small opening of approximately 4 mm in diameter (figure1). Three-dimensional reconstruction of the airway confirmed these findings (figure 2).
ДНК-абзимы при аутоиммунной патологии в клинике и эксперименте (2003)

DNA-abzymes enzymes in autoimmune diseases in clinic and experiment T.E. Naumova, O.M. Durova, A.G. Gabibov, Z.S. Alekberova, S. V. Suchkov DNA-hydrolyzing autoantibodies (AAB) or DNA-abzymes can be found in autoimmune diseases in clinic and experiment. Technology of serum express screening for presence of DNA abzymes is described. Comparative study of DNA-hydrolising activity in patients with different forms of systemic and organ-specific autoimmune diseases was performed. Blood of clinically healthy donors was usually free of IgG DNA-abzymes. DNA-abzymes were most often revealed in patients with systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA) less often in patients with organ-specific forms of autoimmune disturbances. The results of the study confirm the hypothesis of autoimmune origin of IgG DNA abzymes and demonstrate the possibility to use them in clinical practice for monitoring to disease activity in SLE and RA.
Three-Way Handshake for Intermediate System to Intermediate System (IS-IS) Point-to-Point Adjacencies (2002)

The IS-IS routing protocol (ISO 10589) requires reliable protocols at the link layer for point-to-point links.As a result, it does not use a three-way handshake when establishing adjacencies on point-topoint media.This paper defines a backward-compatible extension to the protocol that provides for a three-way handshake.It is fully interoperable with systems that do not support the extension.Additionally, the extension allows the robust operation of more than 256 point-to-point links on a single router.This extension has been implemented by multiple router vendors; this paper is provided as information to the Internet community in order to allow interoperable implementations to be built by other vendors.1.
Ligno cellulosic-ethanol : a second opinion (2003)

Up to now renewable energy sources are primarily used in the Netherlands for electricity production. At the end of the past decade the GAVE programme was launched to facilitate the introduction of climate neutral gaseous and liquid fuels. A comprehensive study by ADL evaluated a large number of options for the production of gaseous and liquid fuels. During the ADL study, the use of bioethanol - produced from lignocellulosic feedstock - as a substitute for gasoline was identified as highly attractive and promising for the reduction of greenhouse gas emissions at a relatively low price. The objectives of this study are: (1) to give an overview of the current technology available for production of ethanol from lignocellulosic feedstocks, and which companies are currently involved in lignocellulosic ethanol; (2) to identify major technological obstacles in the current production scheme, and to indicate which improvements have to be reached for a successful implementation of this technology; and (3) to estimate when and in what way large scale implementation of lignocellulosic ethanol in the Dutch transportation fuel market may be foreseen. Finally, the prospects of reduction of greenhouse gas emissions in the Netherlands by ethanol from lignocellulose are determined.
Cross-layer design for MIMO systems over spatially correlated and keyhole Nakagami-m fading channels (2010)

Cross-layer design is a generic designation for a set of efficient adaptive transmission schemes, across multiple layers of the protocol stack, that are aimed at enhancing the spectral efficiency and increasing the transmission reliability of wireless communication systems. In this paper, one such cross-layer design scheme that combines physical layer adaptive modulation and coding (AMC) with link layer truncated automatic repeat request (T-ARQ) is proposed for multiple-input multiple-output (MIMO) systems employing orthogonal space--time block coding (OSTBC). The performance of the proposed cross-layer design is evaluated in terms of achievable average spectral efficiency (ASE), average packet loss rate (PLR) and outage probability, for which analytical expressions are derived, considering transmission over two types of MIMO fading channels, namely, spatially correlated Nakagami-m fading channels and keyhole Nakagami-m fading channels. Furthermore, the effects of the maximum number of ARQ retransmissions, numbers of transmit and receive antennas, Nakagami fading parameter and spatial correlation parameters, are studied and discussed based on numerical results and comparisons.

International Federation of Gynecology and Obstetrics opinion on reproductive health impacts of exposure to toxic environmental chemicals (2015)

Exposure to toxic environmental chemicals during pregnancy and breastfeeding is ubiquitous and is a threat to healthy human reproduction. There are tens of thousands of chemicals in global commerce, and even small exposures to toxic chemicals during pregnancy can trigger adverse health consequences. Exposure to toxic environmental chemicals and related health outcomes are inequitably distributed within and between countries; universally, the consequences of exposure are disproportionately borne by people with low incomes. Discrimination, other social factors, economic factors, and occupation impact risk of exposure and harm. Documented links between prenatal exposure to environmental chemicals and adverse health outcomes span the life course and include impacts on fertility and pregnancy, neurodevelopment, and cancer. The global health and economic burden related to toxic environmental chemicals is in excess of millions of deaths and billions of dollars every year. On the basis of accumulating robust evidence of exposures and adverse health impacts related to toxic environmental chemicals, the International Federation of Gynecology and Obstetrics (FIGO) joins other leading reproductive health professional societies in calling for timely action to prevent harm. FIGO recommends that reproductive and other health professionals advocate for policies to prevent exposure to toxic environmental chemicals, work to ensure a healthy food system for all, make environmental health part of health care, and champion environmental justice.
Freeway Work Zone Traffic Delay and Cost Optimization Model (2003)

A new freeway work zone traffic delay and cost optimization model is presented in terms of two variables: the length of the work zone segment, and the starting time of the work zone using average hourly traffic data. The total work zone cost defined as the sum of user delay, accident, and maintenance costs is minimized and the number of lane closures, darkness factor, and seasonal variation travel demand normally ignored in prior research are included. To find the global optimum solution, a Boltzmann-simulated annealing neural network is developed to solve the resulting mixed real variable–integer cost optimization problem for short-term work zones. The new model can be used as an intelligent decision support system to (1) find the optimum work zone segment length and optimum starting time; (2) study the impact of various factors such as number of lane closures and darkness; and (3) quickly observe the relation between the total work zone cost and the work zone segment length and starting time in a quantitative and rational way.
Repair of chronic tympanic membrane perforations with long‐term epidermal growth factor (1995)

Chronic tympanic membrane (TM) perforation is a common problem worldwide. Recent reports have shown epidermal growth factor (EGF) to stimulate healing in approximately 80% of chronic TM perforations in chinchillas when applied in three doses over 1 week. The objective of this controlled study is to evaluate the efficacy of long-term EGF in the closure of TM perforations. Chronic chinchilla TM perforations were treated with EGF for up to 6 weeks. One hundred percent (17 of 17) of treatment group perforations completely healed. However, two new findings with this long dosing scheme were reperforation on long-term follow-up and three TMs with cholesteatomas. It is likely that reperforation was due to a progressive thinning seen with prolonged EGF application. Long-term EGF use is not recommended for the treatment of TM perforations because of possible wound healing impairment and possible cholesteatoma induction.
Reduction of the residual stress of various oxide films for MEMS structure fabrication (1999)

Various oxide films are commonly used as a sacrificial layer or etch mask in the fabrication of microelectromechanical systems (MEMS). Large residual strain of these oxide films causes the wafer to bow, which can have detrimental effects on photolithography and other ensuing processes. This paper investigates the residual strain of tetraethoxysilane (TEOS), low temperature oxide (LTO), 7 wt% and 10 wt% phosphosilicate glass (PSG). Euler beams and a bent-beam strain sensor are used to measure the residual strain. A poly silicon layer is used as the sacrificial layer, which is selectively etched away by . First, the residual strain of as-deposited films is measured, which is quite large. The residual strain of the films is also measured after annealing them not only at , , and in environment for 1 hour but also at the conditions for depositing a thick polysilicon at and . Our results show that the 7 wt% PSG is best suited as the sacrificial layer for thick polysilicon processes.
Stimuli-Responsive Macromolecules and Polymeric Coatings (2005)

Polymers represent a unique class of materials which are capable of forming architectural arrangements at molecular, nano- and higher levels of organization. While numerous properties made polymers highly attractive materials in many applications, their stimuli-responsive characteristics have been recognized only recently. This chapter provides an overview of a variety of responses of polymers and polymeric films that exhibit pro-active behaviors in response to internal or external stimuli. These "smart" macromolecules offer a number of unique attributes with potential emerging applications in medicine, pharmacology, nanotechnology, biomaterials, or other fields of materials science and materials engineering. The stimuli-responsive characteristics described herein focus on physical and chemical stimuli that result in numerous responses leading to unique behaviors in complex environments.

CTLA4 promoter polymorphisms are associated with canine diabetes mellitus (2010)

Canine diabetes mellitus (DM) shares many similarities with human type 1 diabetes (T1D). It is a complex genetic disorder, which shows marked differences in breed susceptibility, with Samoyed dogs being highly susceptible, whereas the Boxer breed is relatively resistant. A number of immune response genes, which have been associated with human T1D, have also been implicated in determining susceptibility to canine DM, suggesting an immune-mediated component to the disease pathogenesis. Single nucleotide polymorphisms (SNPs) in the CTLA4 gene have consistently and reproducibly been associated with human T1D and other autoimmune diseases but the canine CTLA4 gene has not previously been investigated for involvement in canine DM. SNPs of particular interest in the human association studies are those in the promoter region which affect CTLA4 expression levels, and that of exon 1 which results in a non-synonymous amino acid change. We performed a canine SNP discovery investigation of CTLA4 on a region of DNA containing exon 1 and 1.5 kb upstream sequence in order to identify promoter region SNPs. Confirmed SNPs were used in a genetic association study of a canine diabetic cohort showing that CTLA4 promoter polymorphisms were associated with diabetes in crossbreed dogs and in five Pedigree breeds-Samoyed, Miniature Schnauzer, West Highland White Terrier, Border Terrier and Labrador. Meta-analysis of these breeds showed 9 out of 15 SNPs were associated with DM and genotype and haplotype analyses also confirmed the allelic associations in these breeds.
Effect of Ionomeric Compatibilizer on Clay Dispersion in Polyethylene/Clay Nanocomposites (2006)

Abstract Summary: Linear low‐density polyethylene (LLDPE)/clay nanocomposites are obtained and studied by using a zinc‐neutralized carboxylate ionomer as a compatibilizer. LLDPE‐ g ‐MA is used as a reference compatibilizer. Two different clays, natural montmorillonite (Closite Na + ) and a chemically modified clay Closite 20A have been used. Nanocomposites are prepared by melt blending in a twin‐screw extruder using two mixing methods: two‐step mixing and one‐step mixing. The relative influence of each compatibilizer is determined by wide‐angle X‐ray diffraction structural analysis and mechanical properties. The results are analyzed in terms of the effect of the compatibilizing agent and incorporation method in the clay dispersion, and the mechanical properties of the nanocomposites. Experimental results confirm that the film samples with ionomer show a good mechanical performance only slightly below that of the samples with maleic anhydride (MA). The two‐step mixing conditions result in better dispersion and intercalation for the nanofillers than one‐step mixing. The exfoliation of clay platelets leads to an improved thermal stability of the composite. The oxygen permeability of the clay nanocomposites, using ionomer as a compatibilizer, is decreased by the addition of the clay.

The European hydrogen and fuel cell Strategic Research Agenda and Deployment Strategy (2005)

In the April issue we reported on the European Commission's Second Annual General Meeting of its European Hydrogen & Fuel Cell Technology Platform, which discussed the Strategic Research Agenda (SRA) and Deployment Strategy (DS) documents that it published at the end of 2004. Here we look at the key points of the SRA and DS reports, and their recommendations to bring hydrogen and fuel cell technologies to market in order to exploit their outstanding environmental and economic potential.
Mechanisms of Action of Nonglucose Insulin Secretagogues (1994)

Insulin release induced by nonglucose secretagogues is initiated from beta-cell by a wide variety of stimuli through specific receptors or binding sites. Activation of receptors in turn generates or enhances the cytosol levels of cAMP, cADPR, IP3, DAG, and AA. These second messengers then activate protein kinases, change the ion currents cross the cell membrane, and mobilize intracellular Ca2+, thereby increasing phosphorylated proteins in the cytosol and augmenting [Ca2+]i. These events trigger exocytotic discharge of insulin. The crucial steps in receptor-mediated stimulation-secretion coupling and their relationship to glucose-stimulated insulin release is summarized in Figure 1. At the present stage of research, the general processes of secretagogue binding to receptors, of generating second messengers, of activating several types of protein kinase, and of altering the membrane potential as well as cytosol calcium levels has been intensively studied and qualitatively clarified. However, we know little about the exact nature of substrates of different protein kinases and their function in the insulin secretion process. With the help of molecular biology and protein chemistry, we expect that this gap will be filled in the near future.

Laparoscopic Gastrostomy and Jejunostomy (1999)

Some patients undergoing laparoscopic enteral access may require deep sedation and a rare patient may require general anesthesia. Clinical conditions and surgeon preference, therefore, should determine whether local anesthesia is suitable for laparoscopic gastrostomies and jejunostomies, and in what setting, since there is no difference in success rate or complications when compared with general anesthesia. Potential savings are possible from the operating room (26% of total cost) or anesthesiologist (12% of total cost) if these procedures are performed in an endoscopy suite without monitored anesthesia care.
From self-organization in relativistic electron bunches to coherent synchrotron light: observation using a photonic time-stretch digitizer (2019)

In recent and future synchrotron radiation facilities, relativistic electron bunches with increasingly high charge density are needed for producing brilliant light at various wavelengths, from X-rays to terahertz. In such conditions, interaction of electron bunches with their own emitted electromagnetic fields leads to instabilities and spontaneous formation of complex spatial structures. Understanding these instabilities is therefore key in most electron accelerators. However, investigations suffer from the lack of non-destructive recording tools for electron bunch shapes. In storage rings, most studies thus focus on the resulting emitted radiation. Here, we present measurements of the electric field in the immediate vicinity of the electron bunch in a storage ring, over many turns. For recording the ultrafast electric field, we designed a photonic time-stretch analog-to-digital converter with terasamples/second acquisition rate. We could thus observe the predicted link between spontaneous pattern formation and giant bursts of coherent synchrotron radiation in a storage ring.
Exploring clinical, echocardiographic and molecular biomarkers to predict bronchopulmonary dysplasia (2019)

The combination of clinical and echocardiographic variables is a valuable tool for determining the risk of BPD. We find the two variable model (mechanical ventilation and echocardiographic signs of PH) more practical for clinical and research purposes. Future research on BPD prediction should be oriented to explore the potential role of ET-1.
