Continuity of symplectically adjoint maps and the algebraic structure of Hadamard vacuum representations for quantum fields on curved spacetime

We derive for a pair of operators on a symplectic space which are adjoints of each other with respect to the symplectic form (that is, they are sympletically adjoint) that, if they are bounded for some scalar product on the symplectic space dominating the symplectic form, then they are bounded with respect to a one-parametric family of scalar products canonically associated with the initially given one, among them being its ``purification''. As a typical example we consider a scalar field on a globally hyperbolic spacetime governed by the Klein-Gordon equation; the classical system is described by a symplectic space and the temporal evolution by symplectomorphisms (which are symplectically adjoint to their inverses). A natural scalar product is that inducing the classical energy norm, and an application of the above result yields that its ``purification'' induces on the one-particle space of the quantized system a topology which coincides with that given by the two-point functions of quasifree Hadamard states. These findings will be shown to lead to new results concerning the structure of the local (von Neumann) observable-algebras in representations of quasifree Hadamard states of the Klein-Gordon field in an arbitrary globally hyperbolic spacetime, such as local definiteness, local primarity and Haag-duality (and also split- and type III_1-properties). A brief review of this circle of notions, as well as of properties of Hadamard states, forms part of the article.Comment: 42 pages, LaTeX. The Def. 3.3 was incomplete and this has been corrected.

Gall-inducing Aphids (Hemiptera: Aphidoidea: Eriosomatinae) Associated with Salicaceae and Ulmaceae in Razavi Khorasan Province, with New Records for Fauna of Iran

A survey of gall-inducing aphids on elm and poplar trees was carried out during 2017 in Razavi Khorasan province, NE Iran. As a result, 15 species of gall-inducing aphids from 5 genera, all belonging to the subfamily Eriosomatinae, were recorded on 6 host plant species. The collected species included the genera Eriosoma, Kaltenbachiella, Pemphigus, Tetraneura and Thecabius. Pemphigus passeki Börner (Hemiptera: Aphididae) and Pemphigus populinigrae (Schrank) (Hemiptera: Aphididae) on Populus nigra var. italica (Salicaceae) were new records for the Iranian aphid fauna. Both new recorded species belong to the tribe Pem-phigini, subfamily Eriosomatinae. Among the identified species, 8 aphid species were new records for Razavi Khorasan province

Study of Prevalence of Martin-Gruber Anomaly in Patients with Carpal Tunnel Syndrome

Median-Ulnar connection in the forearm, also known as the Martin-Gruber communication (MGC), is a common anatomic nerve anomaly with the incidence from 5% to 34% in the normal population. Knowledge of this anomaly is of crucial importance in evaluation of injuries of Median and Ulnar nerves; as well as in accurate interpretation of the nerve conduction velocity of these nerves. This study aimed at evaluating the frequency of martin - Gruber communication and its common types in patients with Carpal Tunnel Syndrome (CTS). 151 patients with definite diagnosed Carpal Tunnel Syndrome by electro-diagnostic method (123 females and 28 males with the mean age of 46.42+/_11.21 years) were enrolled in the study over a 13 months period. 19 patients (12.6 %) -13 females, 6 males-had MGC. In 285 upper extremities with carpal tunnel syndrome, 25 (8.8%) cases had martin - Gruber communication. Types 1, 2 and 3 of this anomaly were seen in 7 (43.8%), 14 (87.5%), 6 (37.5%) patients respectively. In our study the prevalence of Martin - Gruber connection in the patients with carpal tunnel syndrome was within the same range as in literature, however lower than the mean reported value. MGC Type 2 was the most common type in patients with CTS

Diagnosis of premature rupture of membranes by the detection of thyroid hormones in vaginal secretions

Background: Premature rupture of membranes (PROM) and preterm PROM (PPROM) are the rupture of the fetal chorioamniotic membranes before the onset of labor contractions. Objectives: To evaluate whether detection of thyroid hormones in vaginal washouts can be used to diagnose premature rupture of membranes (PROM). Patients and Methods: Total T4 (thyroxin), total T3 (triiodothyronine), and free T4 concentrations in vaginal washouts were analyzed in 45 women with the diagnosis of PROM and compared with 45 normal pregnancies (controls). A Student�s t-test was used for comparison of thyroid hormone values and a ROC curve was used for analyzing the diagnostic accuracy Results: There were no differences between the patients with PROM and the control women regarding maternal age, gestational age, and parity. The mean concentration of total T4 in the PROM group and the control subjects were 2.1 ± 1.3 jig/mL and 1.55 ± 0.58 jig/, respectively (P = 0.01). Total T3 concentration in the PROM group was significantly higher compared to the controls (1.28 ± 0.42 ng/ vs. 0.8 ± 0.26 ng/, P < 0.0001). Also, free T4 concentration was significantly higher in the PROM group as compared with the controls (0.026 ± 0.034 ng/ vs.0.007 ± 0.004 ng/, P < 0.0001). The ROC curve analysis showed that total T4=1.685 jig/ had a sensitivity of 62, specificity of 76, positive predictive value (PPV) of 71.8, and negative predictive value (NPV) of 66.7. Total T3 = 0.82 ng/ gave a sensitivity of 91, specificity of 64, PPV of 72, and NPV of 87.8. Free T4 = 0.01 ng/ gave a sensitivity of 51, specificity of 82, PPV of 74.2, and NPV of 62.7. The best cutoff values were total T4 = 1.685 ng/, total T3 = 0.82 ng/, and free T4 = 0.01 ng/. Conclusions: Detecting total T4, total T3, and free T4 in vaginal washouts of patients suspected of PROM suspected is a simple, available, rapid, and inexpensive method for the diagnosis of PROM. However, a combination of three tests is recommended. © 2015, Shiraz University of Medical Sciences

KEPADATAN MAKROZOOBENTOS DI PERAIRAN PEUNAGA RAYEUK, KECAMATAN MEUREUBO, KABUPATEN ACEH BARAT

Macrozoobenthos are aquatic organisms that live on the bottom and surface of the waters, and are influenced by bottom substrate and water quality. This study aimed at determining the density of macrozoobenthos in Peunaga Rayeuk Waters, Meureubo District, West Aceh Regency in terms of species composition, diversity, uniformity, and dominance. This research was conducted from May to June 2021 in the waters of Peunaga Rayeuk, Meureubo District, West Aceh Regency. Purposive random sampling was employed to collect the data in four stations. Based on the results of the study, 15 types of macrozoobenthos grouped into 3 classes were found, namely bivalves, gastropods and malokostraca. The macrozoobenthos density values at four stations ranged from 308.52 to 1357.49 ind/m2. The percentage value of macrozoobenthos composition by class showed that bivalves had the lowest percentage, as much as 13%, and the highest percentage was the gastropods, as much as 54%. The diversity index (H) ranged from 1.21 to 3.31 which was classified as medium to high category. The uniformity index (e) ranged from 0.81 to 0.92 and was classified as high category, while the Dominance Index (C) ranged from 0.21 to 0.54 and categorized as low to moderate category. The water quality parameter values was still in normal conditions and support the life of macrozoobentho

The Conditions of Coral Reef Ecosystem on Seureudong Island, South Aceh

The coral reef ecosystem on Seureudong Island, Sawang Bau Village, Sawang District, South Aceh is very important for the surrounding ecosystem, with the fringing reef type, namely the shape of its growth around the island. This study aims to determine the current condition of coral cover and the types available on Seureudong Island. The method used is the Point Intercept Transect (PIT). The results showed that the forms of coral found at the study site were branching, digitate, encrusting, foliose, massive, mushroom, plates, and submassive. &nbsp;The percentage of the bottom substrate is dominated by hard coral (hard coral) at 45.3%, Dead Coral with Algae/DCA (37.11%), and (9.89%), rubble of 3.56%, rock (1.56%), algae turf (1.44%), macroalgae (1%) and dead coral (0.11%). At the study site, 25 genera were found with Porites (36%) as the most common genus found. At the research location, there are also genera with a total presence of less than 1%. These genera are Acanthastrea, Ctenactis, Favia, Favites, Fungia, Gardineroseris, Goniopora, Halimeda, Heliopora, Hydnophora, Leptastrea, Montastrea, Pavona, and Seriatopora. &nbsp;The quality of the waters at the research location still complies with the standards of coral life. The results of these observations must be carried out periodically so that they can always update the condition of the coral reefs on Seureudong Islan

Non-Linear Seismic Response of Base-Isolated Frame Structures Using Rubber Bearings

Over the past two decades, much progress has been made in research and application of the base isolation of structures as means of providing earthquake resistance to a structure. However, the trade-off between the extent of acceleration reduction and the response of a base-isolation system has not been given a serious consideration. This work uses a new material constitutive model for rubber bearing base-isolation system, which adopts the technique of real-time structural parameter modification. To achieve this, a finite element modeling and analysis are performed as a comparative study between a conventional totally fixed-base steel frame structure and similar base-isolated structures using rubber-steel bearings. The structures are subjected to the El-Centro, N-S earthquake. In order to include nonlinearity effects, a non-linear hyperviscoelastic material model has been used and linked to ABAQUS software as a user defined material subroutine (i.e., UMAT). Special connector elements are selected from ABAQUS library to connect the rubber bearings to the frame structure and the foundations in order to achieve the required kinematical constraints at the connection points. The model is validated by carrying out a comparative study of the results obtained from the analysis of the presented material model with those obtained by using the existing ABAQUS material models (e.g., Ogden material model). The results show a significance efficiency of using the rubber bearing isolation in order to uncouple the structure from the seismic ground motion. Moreover, it has been proved that the used material model is more effective to capture the behavior of the base-isolated structures expressing a notable reduction in acceleration and an increase in the structural resistance to earthquake excitations
