Identification of a class of time-varying nonlinear systems using basis sequences

We consider the identification of a class of time-varying nonlinear systems, called the time-varying Hammerstein series. This identification problem is motivated by the practical need to characterise time-varying nonlinear systems in a simple and parsimonious manner. Basis sequences are introduced to facilitate a reduction in system parameterisation and also to make the estimation task tractable. A significant advantage of the approach is that only a single input-output record is required to obtain least-squares estimates of the model coefficients. The selection of basis sequences and basis order is also discussed. Simulated and real data results are presented to indicate the usefulness of the proposed identification technique. We were interested in applying the time-varying nonlinear system identification procedure to a modelling scenario in seismology.

Studies on Canine Pancreatic Secretion

THE RESPONSE TO HISTAMINE. The pancreatic response to histamine and to control injections of secretin have been studied in 8 dogs. To exclude any fallacy due to activation of the endogenous secretin mechanism by gastric acid, 3 of the dogs had total gastrectomies carried out, and 5 dogs had gastrostomies through which the stomach could be kept empty. Histamine is a potent stimulator of pancreatic secretion in the absence of the endogenous secretin mechanism. The volume, bicarbonate concentration, and total bicarbonate output in response to histamine are on the average about 70% of the response to secretin in the doses used, and on occasion may even be greater than it. The concentrations of chloride and nitrogen in response to histamine are about 2-J times the corresponding concentrations in response to secretin, but the total outputs are approximately equal. The profiles of the responses to histamine and secretin are very similar as regards latent period, duration of response, and the timing of the peak of the response. 'Histamine is a true pancreatic secretagogue. Its action cannot be explained by activation of the endogenous secretin mechanism by gastric HCl, by direct secretin release, or by lowering of the threshold to secretin. It is not due to the concomitant secretion of bile, to vasodilatation, to lowering of the blood pressure, or to an increase in blood, flow through the pancreas. THE EFFECT OF ATROPINE. The effect of atropine on the response to histamine has been studied on 3 dogs with total gastrectomies and 4 dogs with gastrostomies. Atropine inhibits the volume and bicarbonate output in response to histamine and tnis inhibition may be complete when one hour is allowed to elapse between the injection of atropine and the subsequent injection of histamine. When an interval of only half an hour is allowed, inhibition does not invariably occur. The effect of atropine on the pancreatic response to secretin has been studied in one dog. Atropine produces a small but important reduction in the volume response to secretin. Atropine produces a significant increase in the bicarbonate concentration, but little change in the total bicarsbonate output in response to secretin. Both the concentration and total output of nitrogen are significantly decreased by atropine. The concentration and total output of chloride were not significantly affected by atropine. Vagotomy reduced the inhibitory effect of atropine on the concentration and total output of nitrogen to a significant degree, and reduced the increase in the bicarbonate concentration. Atropine appears to act directly on the secretory cell as well as blocking the secretory fibres of the vagus. (Abstract shortened by ProQuest.).

Preliminary Excavations in the Gardens of Hadrian's Villa: The Canopus Area and the Piazza d'Oro

Preliminary excavations in 1987–1988 in the Canopus area and in the Piazza d'Oro indicate that Hadrian's Villa contains much important evidence for our knowledge of ancient Roman gardens. On the west bank of the Canopus evidence was found of elaborate terraced gardens still covered with undisturbed soil and on the east bank a row of discarded amphoras was discovered. The amphoras had been cut in half and used as planting pots, giving significant information about the planting pattern.In the Piazza d'Oro a sloping tufa terrain with an insufficient soil covering for plants made it necessary for Hadrian to cut planting holes into the tufa; these were then filled with fertile soil. Large planting pits were found in 1987–1988 that appear to continue around the edge of the garden. In the bed on the west side of the euripus an intricate network of trenches cut to provide drainage for the planting beds was found, as well as smaller planting holes. Subsequent excavations made it possible to explain the unique irrigation system of this garden.

Retrograde shear stress modulates rat mesentery microvessel permeability and endothelial adhesion structures

Vascular endothelial cells (EC) orient their long axis parallel to the fluid flow direction both in vivo and in culture. The EC surface glycocalyx transduces the fluid flow shear stress that mediates nitric oxide production (Florian et al. Circ Res 2003) and EC cytoskeletal rearrangement (Thi et al. PNAS 2004). To test that in vivo shear stress regulates EC adhesion structures and permeability we compared final hydraulic permeability (L p ) measured in rat mesentery venular microvessels perfused orthograde with L p measured in vessels perfused retrograde, both for about 3 hours. Shear stress ranged from 0.2 to 17 dyne/cm 2 in the retrograde group and from 3.2 to 36 in the orthograde group. For retrograde vessels L p (range 0.4 to 30 x 10 −7 (cm/s * cmH 2 O)) was significantly correlated (p &lt; 0.05) to mean shear stress, with a linear regression slope 1.5 x 10 −7 (cm/s * cmH 2 O)/(dyne/cm 2 ) and L p intercept ‐0.6 x 10 −7 (cm/s * cmH 2 O). For orthograde vessels the L p (2.0 ± 0.6 x 10 −7 (cm/s * cmH 2 O)) was not correlated with mean shear stress. We also examined the continuity of the adhesion protein VE cadherin (VE) and that of the tight junction protein occludin (Oc). Significantly more discontinuities were observed for both VE and Oc in the retrograde group than in the orthograde group. In vivo reversal of flow direction stimulates increased L p correlated with shear stress and induces rearrangement of cytoskeletal structures. HL44485

STAT3 Promotes Apoptosis of Alveolar Epithelial Cells by Inhibiting AKT Signaling

Type II alveolar epithelial cells are a crucial component of alveolar epithelium, and transcriptional activator 3 (STAT3) have functions in regulating alveolar epithelial cell proliferation. Therefore, based on the modular approach, we analyzed the effects of silencing STAT3 on type II alveolar epithelial cells and studied its mechanism of action. Initially, in the GEO database, we downloaded data on type II alveolar epithelial cells. For transcript to me data in alveolar epithelial cell samples, we performed a differential analysis. Secondly, protein interaction network analysis (PPIs) were performed on the differential genes, and the PPIs were analyzed modularly. The module gene was subjected to enrichment analysis of GO function and KEGG pathway. Non-coding RNAs and transcription factors that regulate the module are predicted based on hyper geometric testing. Thus, we have a total of 13 dysfunction modules. These modular genes are significantly involved in biological processes such as nuclear membranes, embryonic organ development, and regulate the insulin signaling pathway and the PI3K-Akt signaling pathway substantially. We identified vital ncRNA pivots (miR-205-5p) and TF pivot (Eomes, Etsl, Nfkbl, Spi1, Statl, Usfl) to regulate dysfunction modules significantly. Our work deciphered a co-expression network that involved essential gene regulation of type II alveolar epithelial cell apoptosis. It helps to reveal the regulation of silencing STAT3 gene on alveolar epithelial cell apoptosis and deepen our understanding of the mechanism. More importantly, we explained that the silencing gene STAT3 inhibits the apoptosis of alveolar epithelial cells by activating the AKT signaling pathway, providing a new theoretical reference for the study of alveolar epithelial cells.

Recalcitrant Erythrodermic Psoriasis Complicated by Septic Shock and Mycotic Aneurysm: A Call for Treatment Guidelines

Erythroderma is characterized by diffuse erythema and scale covering over 90% body surface area that can affect individuals with inflammatory dermatoses such as psoriasis. Complications of erythrodermic psoriasis include infection and cardiovascular compromise. Here we present a case of a 68 year-old man who was hospitalized for erythrodermic psoriasis refractory to multiple immunosuppressive and immunomodulatory therapies, ultimately developing sepsis due to bacteremia and fungemia complicated by infective endocarditis and a mycotic aneurysm. Although the widespread loss of epidermal function in erythroderma increases the risk of infection by opportunistic pathogens, water loss, and electrolyte imbalances, there are very few reported cases of psoriatic erythroderma complicated by fungemia and mycotic aneurysm. Given the high mortality associated with widespread epidermal dysfunction, there is a great need for evidence-based treatment guidelines for psoriatic erythroderma.

PHA stimulation of peripheral blood lymphocytes in oral lichen planus. Abnormality localized between interleukin-2 receptor ligand formation and gamma-interferon secretion.

Peripheral blood T cell function in five oral lichen planus (OLP) patients and five healthy controls was assessed using different activation parameters. Staining with monoclonal antibodies against interleukin-2 receptor and MHC locus II coded Ia antigen, 3H-thymidine incorporation and gamma-interferon secretion were determined in phytohaemagglutinin (PHA) stimulated peripheral blood mononuclear cell cultures at days 0, 1, 3 and 5. The peripheral blood T cell subsets and spontaneous MHC locus II antigen expression were similar in OLP patients and in controls whereas the spontaneous lymphocyte proliferation was lower in OLP patients than in controls (p less than 0.01). This may reflect a slight in vivo preactivation and its effect on lymphocyte recirculation. The PHA-induced expression of IL-2 receptor and T cell proliferation were similar in both groups whereas gamma-interferon secretion and MHC locus II antigen expression were low in OLP patients compared with controls (p less than 0.01). The results suggest a defect in OLP T cell activation disclosed by in vitro PHA stimulation and localized between IL-2 receptor ligand binding and gamma-interferon secretion.

23. European consumer law

This chapter examines EU consumer law. In recent years, international, supranational, and national events alongside technological developments have had and will continue to have a profound effect on EU consumer law. The Covid-19 pandemic has changed consumption habits which, together with rapid digitalization, have created new challenges and risks for consumers, testing the limits not only of older but also more recent EU consumer legislation in a range of sectors. In this context, this chapter discusses the negative impact of EU law on national consumer protection rules; rules on information duties (including the duty to not mislead) and the right of withdrawal; rules establishing consumer expectations; rules on product safety and product liability; and rules on unfair terms and sale of goods. The chapter also covers EU legislation providing general substantive rights; enforcement of consumer protection rules; and consumers’ right of private redress.

The generating function of ergodic distribution in the M/G/1 system with vacation at the beginning of the busy period

Many queueing systems are investigated by means of the embedded Markov chain technique deriving on such way the generating function for the probability distribution. There exists another approach, namely the stationary probabilities are obtained on the basis of regenerative processes considering the regenerative cycles and the mean values of time spent in different states during them. In the paper we get the generating function of ergodic distribution starting with these probabilities for a system with adjustment at the beginning of busy period.

Diffusive shock acceleration of cosmic ray and gamma radiation from young supernova shells

S. ; Ptuskin, V. S. Abstract The generation of gamma radiation produced by the protons accelerated at shock fronts in young SN II envelopes is considered. The shocked gas is known to form the shell limited by the inner and outer shock fronts. The radiation results from p-p interactions inside the shell through production and decay of pions. The flux of gamma rays expected from SN II in the Galaxy are shown to be detectable. The signature of the considered mechanism is early production of the signal, whereas the radiation produced inside the envelope is emitted when transparency sets in.

Successful Long-term Immunotherapy for Human Seminal Plasma Anaphylaxis

Anaphylactic sensitivity to her husband's seminal fluid occurred in a 46-year-old woman six weeks after a hysterectomy. Her husband was azoospermic as a result of an elective vasectomy. A pooled sample of his seminal fluid was used for skin and laboratory tests. Fractionating (Sephadex G100) chromatography was also performed on his seminal fluid. The patient showed positive intracutaneous skin tests to his unfractionated seminal plasma and a Sephadex G100 fraction designated No. 3. This fraction was also passively transferable to a nonallergic volunteer and it stimulated histamine release from the patient's leukocytes. The dose-response effects of this fraction compared with unfractionated seminal plasma in these assays showed greater bioactivity. After informed consent was obtained, the patient was immunized to fraction 3 in a classic desensitization protocol. Two weeks after the final dose of immunotherapy, intercourse was performed without condoms in a medical facility and under the supervision of a physician. No adverse symptoms were experienced by the patient on this occasion. Regular and frequent sexual activity is required to maintain her tolerant state.

Infrared Spectrum of CF3SF5

The infrared spectrum of CF3SF5 has been measured and analyzed between 30 and 4000 cm−1. A band found at 218.5 cm−1 is believed responsible for satellite lines observed previously in the microwave spectrum; the barrier to internal rotation might then be much lower than obtained previously by assuming these satellites were due to torsional oscillation. Twelve of the seventeen fundamentals were assigned in the infrared spectrum and estimates are given for the others. A plausible assignment is given for the overtone and combination bands also observed; this gives no evidence for any of the inactive fundamentals.

La normalizzazione del lessico artistico francese: il «dizionario» di Félibien

During the reign of Louis XIV, the figurative arts serve the royal propaganda and glorification of the sovereign. The essay Des Principes de l’Architecture, de la Sculpture et de la Peinture (1676) was written by the historian André Félibien with the aim of describing arts during the Grand Siècle. This essay contains one of the first specialised dictionaries on artistic lexicon. In this article, we aim to analyse the structure and contents of the dictionary (nomenclature, syntactic and semantic categories, definitions, specialised marks). Moreover, we will focus on the preface of the essay, in which the author describes the difficulties encountered in the terminological description of the artistic domain.

Parenteral sparfloxacin compared with ceftriaxone in treatment of experimental endocarditis due to penicillin-susceptible and -resistant streptococci

A new, investigational, parenteral form of sparfloxacin was compared with ceftriaxone in the treatment of experimental endocarditis caused by either of three penicillin-susceptible streptococci or one penicillin-resistant streptococcus. Both drugs have prolonged half-lives in serum, allowing single daily administration to humans. Sparfloxacin had relatively low MICs (0.25 to 0.5 mg/liter) for all four organisms and was also greater than or equal to eight times more effective than the other quinolones against 21 additional streptococcal isolates recovered from patients with bacteremia. Ceftriaxone MICs were 0.032 to 0.064 mg/liter for the penicillin-susceptible strains and 2 mg/liter for the resistant isolate. Both antibiotics resulted in moderate bacterial killing in vitro. Rats with catheter-induced aortic vegetations were inoculated with 10(7) CFU of the test organisms. Antibiotic treatment was started 48 h later and lasted either 3 or 5 days. The drugs were injected at doses which mimicked the kinetics in human serum produced by one intravenous injection of 400 mg of sparfloxacin (i.e., the daily dose expected to be given to human adults) and 2 g of ceftriaxone. Both antibiotics significantly decreased the bacterial densities in the vegetations. However, sparfloxacin was slower than ceftriaxone in its ability to eradicate valvular infection caused by penicillin-susceptible bacteria. While this difference was quite marked after 3 days of therapy, it tended to vanish when treatment was prolonged to 5 days. In contrast, sparfloxacin was very effective against the penicillin-resistant isolate, an organism against which ceftriaxone therapy failed in vivo. No sparfloxacin-resistant mutant was selected during therapy. Thus, in the present experimental setting, this new, investigational, parenteral form of sparfloxacin was effective against severe infections caused by both penicillin-susceptible and penicillin-resistant streptococci.
