Deterministic Modeling for Radiation Attenuation-integrated Radon Transform in Emission Computed Tomography: Algorithm, Curve Fitting Analysis, and Introduction of Attenuation Hadamard Matrix

Purpose: The purpose of the study is to propose an algorithm to implement and visualize radiation attenuation-integrated Radon transform based on Beer–Lambert law during emission computed tomography simulation using a deterministic model and also to perform image analysis on resulting images. Methods: Two types of phantoms are designed: plain-disk phantom and patterned-disk phantom. The large disk is filled with an activity of 5 units and the smaller disks have 10 units of activity of 99mTc isotope as an emission map. Three transmission maps for patterned-disk phantom are created with uniform linear attenuation coefficient. Phantoms are scanned with 360° and 180° acquisition arcs. Then, using the algorithm designed, the exponential Radon transform is implemented. After that, the projections are back-projected and filtered to generate tomographic slices. Finally, all slices are analyzed using profile plotting and curve fitting. Moreover, an attenuation Hadamard matrix is provided to facilitate attenuation modeling. Results: The uniform intensity of activity in the phantoms is converted to a disk with progressively decreasing intensity from the periphery to the center in the tomographic slices. Similarly, the circles positioned more centrally appear less intense than those positioned in the periphery, despite all circles having equal activity. When the phantom is scanned in 180° arc, the circles closest to the camera are visualized more intensely. The profile curves of the slices generated by exponential Radon transformation are depicted as U-shaped in profile plotting and are fitted to a bi-exponential function with a near-perfect precision. Conclusions: The incorporation of radiation attenuation results in the development of more realistic models for quantification purposes.
Prevalence and antibiotic resistance patterns of Aeromonas and Pseudomonas species recovered from aquatic foods sold at the retail market in Egypt.

Keywords Overuse of antibiotics in the fish and shellfish production systems throughout time may be one of the primary causes of growing antibiotic resistance in bacteria. In this study, 90 samples of Nile Tilapia, Mugil, and shrimps were tested for the presence of Aeromonas and Pseudomonas species and monitored their antibiotic resistance pattern. The isolated bacterial strains were identified based on morphological and biochemical characteristics. Further, the isolates were tested against 14 antimicrobial agents using the disc diffusion method, and the multidrug resistance pattern was studied. The results showed that across the three sample types, Pseudomonas fluorescens (26.7%) and Aeromonas hydrophila (21.1%) were the most common, followed by A. caviae (14.4%), P. putrefaciens (13.3%), A. sobria (12.2%), P. fragi (11.1%), P. alcaligenes (10%), A. veronii (5.6%), P. proteolytica (4.4%), P. aeruginosa (3.3%), P. cepacian (2.2%), and A. fluvialis (1.1%). The two most common strains were submitted for susceptibility analysis that revealed multidrug-resistant. For Aeromonas hydrophila the highest rates of resistance were to streptomycin (100%) and penicillin G (92.3%), then erythromycin (84.6%) and cefotaxime (84.6%). For Pseudomonas fluorescens highest rates of resistance were to Nalidixic acid (100%) and streptomycin (100%), then erythromycin (91.7%), penicillin G (79.2%) and cephalothin (75%). Pseudomonas fluorescens and Aeromonas hydrophila had average multiple antibiotic resistance indexes of 0.521 and 0.494, respectively. In conclusion, fish, and shellfish sold in the Egyptian market act as a reservoir for the multi-resistant Aeromonas and Pseudomonas genera. These significant findings call for effective risk assessment models and management plans that protect human, and animal.

There is an increasing body of literature related to sampling for network and spatial settings. Although current link-tracing methods like adaptive cluster sampling, snowball sampling, and targeted random walk designs have advantages over conventional designs, some of the following drawbacks remain evident: there is a lack of flexibility in sample placement; there is an inability to control over sample sizes; and efficiency gains over conventional sampling designs for estimating population parameters may not be achievable. Adaptive web sampling (AWS) is a recently developed link-tracing design that overcomes some of these issues. Furthermore, the flexibility inherent to the AWS method permits many design variations. Using a simulated network population, an empirical population at risk for HIV/ AIDS, a simulated spatial population, and an empirical population of birds, this project performs a simulation study to compare the performance of three variations of AWS strategies.
New Mexico Geological Society

A study of 86 samples of trachyandesitic and dacitic lava and cinders from the Los Lunas volcano, central New Mexico, demonstrates the volcano consists of two overlapping but temporally and compositionally distinct eruptive edifices differing in age by 2.56 Ma. Lava compositions at Los Lunas volcano are consistent with other lavas found in the Rio Grande rift, but, based on major and trace element determinations, no simple model can be proposed to genetically link the two dominant magma compositions. Rather, the two magma batches appear to have been independently generated, consistent with the large age gap between eruptions of the two edifices. An experiment carried out as part of this study indicates that the accuracy and precision of 40Ar/39Ar dates for young mafic to intermediate lavas can be maximized by selecting samples that contain K-feldspar as a late-crystallized phase, and contain little or no glass or alteration phases. Characterization of samples was undertaken using the electron microprobe, where samples were ranked on a scale of 1 to 10 (with 10 being most suitable for dating) based largely on whether the K in the sample could be determined to be housed in extremely fine-grained feldspar interstitial to more abundant phenocryst phases, or was in residual volcanic glass. Sample rating was downgraded if the sample showed evidence of chemical alteration. The 40Ar/39Ar results from the most highly rated samples yield an age of 3.83±0.05 Ma for the Southwest Edifice of Los Lunas volcano. This volcanic center is physically overlapped by the 1.271±0.014 Ma Main Edifice. The absolute ages agree with relative ages determined from geological mapping. Within the Main Edifice, field relationships indicate a sequence of five eruptive events. The ages of the best samples from the Main Edifice all agree within analytical error, suggesting that the entire period of eruptive activity spanned less than 100,000 years. The precision and accuracy of data in this study were much enhanced by using microprobe observations of groundmass glass and K-feldspar to aid in the sample selection process. Sample selection based only on thin section observations would have yielded lower quality data, because the degree of crystallization of residual glass would have been incompletely assessed. 203
Heterogeneous oxidation of saturated organic aerosols by OH 4189 ToF-AMS N 2 UV lamp Reactor Flow Tube Aerosol Source DMA CPC O 3 Denuder BES Water Bubbler Mixing Flow Tube Neutralizer

The kinetics and reaction mechanism for the heterogeneous oxidation of saturated organic aerosols by gasphase OH radicals were investigated under NO x-free conditions. The reaction of 150 nm diameter Bis(2-ethylhexyl) sebacate (BES) particles with OH was studied as a proxy for chemical aging of atmospheric aerosols containing saturated organic matter. An aerosol reactor flow tube combined with an Aerodyne time-of-flight aerosol mass spectrometer (ToFAMS) and scanning mobility particle sizer (SMPS) was used to study this system. Hydroxyl radicals were produced by 254 nm photolysis of O3 in the presence of water vapour. The kinetics of the heterogeneous oxidation of the BES particles was studied by monitoring the loss of a mass fragment of BES with the ToF-AMS as a function of OH exposure. We measured an initial OH uptake coefficient of γ0=1.3 (±0.4), confirming that this reaction is highly efficient. The density of BES particles increased by up to 20% of the original BES particle density at the highest OH exposure studied, consistent with the particle becoming more oxidized. Electrospray ionization mass spectrometry analysis showed that the major particle-phase reaction products are multifunctional carbonyls and alcohols with higher molecular weights than the starting material. Volatilization of oxidation products accounted for a maximum of 17% decrease of the particle volume at the highest OH exposure studied. Tropospheric organic aerosols will become more oxidized from heterogeneous photochemical oxidation, which may affect not only their physical and chemical properties, but also their hygroscopicity and cloud nucleation activity.

Now You Don ’ t : Transient Traces of Consonants and their Nonspeech Analogues in the Human Brain

The apparently effortless identification of speech is one of the human auditory cortex’ finest and least understood functions. This is partly due to difficulties to tease apart effects of acoustic and phonetic attributes of speech sounds. Here we present evidence from magnetic source imaging that the auditory cortex represents speech sounds (such as [g] and [t]) in a topographically orderly fashion that is based on phonetic features. Moreover, this mapping is dependent on intelligibility. Only when consonants are identifiable as members of a native speech sound category is topographical spreading out in the auditory cortex observed. Feature separation in the cortex also varies with a listener’s ability to tell these easy-to-confuse consonants from one another. This is the first demonstration that speech-specific maps of features can be identified in human auditory cortex, and it will further help us to delineate speech processing pathways based on models from functional neuroimaging and non-human primates.
Pan-sharpening quality investigation of PLÉIADES-1A images

Abstract Optical remote sensing satellites obtain MS and Pan images simultaneously over the same coverage area. Remote sensing and image processing communities are working on different pan-sharpening methods capable of taking advantage of MS and Pan images. Each remote sensing system has its own advantages and disadvantages, leading to the question ‘Which pan-sharpening method should be used for which type of imagery? ’ The aim of this research is to investigate the pan-sharpening performance of PLÉIADES-1A images. For this purpose, pan-sharpened images were generated using PCA, IHS and Brovey Transform which are the most popular pan-sharpening methods. Then, the pan-sharpened images were evaluated quantitatively using Correlation Coefficient, Root Mean Square Error, Relative Average Spectral Error, Spectral Angle Mapper and Erreur Relative Globale Adimensionnelle de Synthése. In addition, pan-sharpened images were evaluated qualitatively by taking object availability and completeness into consideration.
Invasion of an alien palm (Trachycarpus fortunei) into a large forest

Range expansion of an alien palm (Trachycarpus fortunei) was studied in a continuous forest in Kanagawa Prefecture, Japan. Life history was studied in a mature population close to a residential area. A 1km x 1km plot in continuous forest was divided into 100m x 100m subplots and the presence or absence of adults and juveniles was recorded in each subplot. The palm formed an erect trunk after reaching 120cm in leaf length and started to produce flowers after the trunk length reached 2m. Maximum height was 6m. Adult plants were found in subplots close to residential and agricultural areas. Juveniles were found around the subplot with adults, and their distribution was spreading into the forest. In the forest the rate of range expansion from the estimated colonisation kernel was slower than in the fragmented suburban landscape. A smaller probability of flowering under the forest canopy may be a reason for shorter colonisation distance. Despite strong shade tolerance in juveniles, the demand for light in the flowering stage, and the small maximum height suggest that the palm will not dominate inside the natural forests. However they may reproduce in abandoned coppice forest, disturbed forest (canopy dieback), forest edges and cliff side forests, and the juveniles can persist for many years under a closed canopy. The species composition of forests is likely to be changed by this alien palm.
Infrared and visible image fusion based on nonsubsampled Contourlet transform

A fusion algorithm based on the Nonsubsampled Contourlet Transform(NSCT) is proposed to fuse infrared and visible images.A weighted averaging′ scheme based on the physical features of infrared and visible images and a selection principle based on the local energy matching are presented for the low frequency subband coefficients and the high frequency subband coefficients,respectively.Experimental results show that the NSCT has a fast computing ability and can provide more image information due to the concentration energy by image processing.As compared to the image fusion algorithm based on pixels,this algorithm has higher fusion performance,and is a Multiscale Geometric Analysis(MGA) tool more suitable for image fusion.
Strain accumulation in the Shumagin Seismic Gap, Alaska

Strain accumulation in the Shumagin seismic gap was estimated from repeated trilateration surveys made between 1980 and 1985. The measured rate of shear-strain accumulation (0.01 ± 0.03 μrad/a) was an order of magnitude less than the rate (0.18 μrad/a) predicted for seismic subduction. The absence of measurable shear-strain accumulation in the Shumagin Islands suggests that the main thrust zone there may not be locked but rather may slip stably. If this is indeed the case, the probability of a great, shallow thrust earthquake in the Shumagin gap is greatly diminished. A moderate earthquake (mb = 6.0) occurred at the seaward end of the trilateration network 4 months after the most recent survey. However, no significant anomalies that could be interpreted as precursors were detected in that survey.

Digital Feminist Placemaking: The Case of the “Woman, Life, Freedom” Movement

Throughout Iran and various countries, the recent calls of the “Zan, Zendegi, Azadi” (in Persian), “Jin, Jiyan, Azadi” (in Kurdish), or “Woman, Life, Freedom” (in English) movement call for change to acknowledge the importance of women. While these feminist protests and demonstrations have been met with brutality, systematic oppression, and internet blackouts within Iran, they have captured significant social media attention and coverage outside the country, especially among the Iranian diaspora and various international organizations. This article, grounded in feminist urban theories of the Global South, analyzes the digital feminist placemaking movement in Iran. As the first counter-revolution led by women, the movement utilizes digital art, graffiti, and protest movements to embody women’s solidarity groups and sympathy rallies. Our analysis employs various digital research methods, including social media scrutiny and the study of protest illustrations. Analyzing the digital feminist placemaking in Iran will enable us to compare the commonalities, differences, challenges, and opportunities between the minorities and majorities in the world’s countries. The outcomes of this research can help international organizations such as Amnesty International and the United Nations Agency for Gender Equality and Women’s Empowerment (UN Women), as well as policymakers, institutions, academics, and NGOs, to highlight the various ways in which broader public participation could be encouraged in the process of digital feminist insurgent placemaking.
Découverte d'une importante lacune stratigraphique à la limite Domérien-Toarcien : implications paléo-océanographiques

In contrast with the majority of recently published hypotheses, we believe that the main trigger for Early Toarcian anoxia is neither increased primary productivity during Tenuicostatum and Falciferum zones nor sudden hydrated-methane degassing close to the transition between these two zones. In our opinion, this peculiar palaeo-oceanographic episode is linked to a major, though short-lived, regression at the end of Upper Domerian due to sudden cooling because of increased volcanic activity followed by global thermal insulation and subsequent glaciation. This regression is responsible for a major hiatus over the whole NW-European province and is later followed by the well-known Lower Toarcian transgression. The interval corresponding to this hiatus (200 to 300 ky) allowed colonisation by vegetation of vast newly emerged surfaces for quite a long period. The teaching and drowning of the accumulated organo-humic matter then triggered the anoxic cycle at the transgressive maximum, concomitant with a global warming.
Reducing Update Cost of TCAM-Based Flow Table

In Software-Defined Networking(SDN), traffic forwarding delay depends on the latency of flow table updating. With increasing fined-grained flow control requirements, more and more frequent operations occur in flow tables inserting or removing forwarding rules. Meanwhile, the matching fields of the rules may overlap, which implies dependency relationships among rules. The dependencies impose restrictions on forwarding rules during updating, e.g., updating order, storage locations of rules, especially in the TCAM-based flow table. Otherwise, mismatching or packet dropping will occur. It usually takes a while to resolve and maintain dependencies during updating, which hinder forwarding efficiency. In this paper, we propose an updating algorithm for TCAM-based flow table to reduce update delay of dependent rules. We first propose and prove an optimal moving chain for a single rule update with the minimum moving steps, and then design a heuristic approach to update concurrent rules dynamically. We evaluate our flow table updating algorithm with different dependency complexities, and the results show that our updating approach achieves about 6% less moving steps than existing approaches.

Effects of straw mulch control soil and water loss increase as cover rate increases.
The Heat Is on: a Simple Method to Increase Genome Editing E�ciency in Plants

Background: Precision genome mutagenesis using CRISPR/Cas has become the standard method to generate mutant plant lines. Several improvements have been made to increase mutagenesis e�ciency, either through vector optimisation or the application of heat stress. Results: Here, we present a simpli�ed heat stress assay that can be completed in six days using commonly-available laboratory equipment. We show that three heat shocks (3xHS) e�ciently increases indel e�ciency of LbCas12a and Cas9, irrespective of the target sequence or the promoter used to express the nuclease. The generated indels are primarily somatic, but for three out of �ve targets we demonstrate that up to 25% more biallelic mutations are transmitted to the progeny when heat is applied compared to non-heat controls. We also applied our heat treatment to lines containing CRISPR base editors and observed a 22-27% increase in the percentage of C-to-T base editing. Furthermore, we test the effect of 3xHS on generating large deletions and a homologous recombination reporter. Interestingly, we observed no positive effect of 3xHS treatment on either approach using our conditions. Conclusions: Together, our experiments show that heat treatment is consistently effective at increasing the number of somatic mutations using many CRISPR approaches in plants and in some cases can increase the recovery of mutant progeny.
Amphibians of Peninsular India

Frogs and toads have always fascinated man through the ages, dating back to Mandukya Upanishad of the Vedic ages to the cent discoveries in the Western Ghats. More technically known as ‘amphibians’ (Greek equivalent for their biphasic life stages as tadpoles and adults), these include caecilians, salamanders, newts, and sirens. Amphibians are in serious scientific contention over the last decade for at least two main reasons. One being far more crucial, pertaining to their viable existence as there are alarming indications of decline in their global population, and the other on the frequent discoveries from biodiversity hotspot regions like Sri Lanka and the Western Ghats of India, emphasizing the linkages of phylogeography, evolution, etc. This book by Daniels, has landed in the stands at a right time, when more and more researchers are getting into the field of herpetology with a fewer number of experienced researchers remaining in it (or at least in this part of the globe).
Time-Lapse Ambient-Seismic-Noise Tomography at Valhall

We show that ambient seismic noise can be used to detect long-term velocity changes in Scholte-wave velocities at microseism frequencies. Two approaches to detect a time-lapse change in Scholte-wave velocities are tested: a data-domain and an image-domain approach. We rely on straight-ray tomography of perturbed traveltimes for imaging. The first approach is based on differentiating phase traveltime changes in the data domain. The second approach is based on differentiating group velocities in the image domain. Both methods work very well and compare well to a time-lapse image computed from controlled-source data. The time-lapse response is dominated by near-surface geomechanical effects of productioninduced reservoir compaction.
Author Manuscript, Published in "international Symposium on Intelligent Vehicles Vehicle Identification Using Infrared Vision and Applications to Cooperative Perception

— Vehicles will be in the next future equipped with V2V telecommunication means to exchange data, such as the presence of an obstacle on the road, or an emergency braking notification. Vehicles are also more and more equipped with perception systems (cameras, laser scanners, radars) that enable them to explore the immediate environment, including other vehicles. We propose in this paper an on-board optical vehicle identification system to enable telecom and perception systems to cooperate. The optical identification identifies which vehicle, in the scene captured by the perception system, is sending information via telecom.
