Theoretical investigation of μ‐O‐bridged dinuclear Re complexes: Electronic structure, bonding nature, and absorption spectra

Field: Chemistry (Physical Sciences)

Abstract The ground state and some low‐lying excited states of [Re 2 IV (μ‐O) 2 (NH 3 ) 8 ] 4+ ( 1 ) and [Re III Re IV (μ‐O) 2 (NH 3 ) 8 ] 3+ ( 2 ) were theoretically investigated with the second‐order Møller–Plesset perturbation theory (MRMP2) and B3LYP methods. Their ground states were assigned to be the 7 B and 6 B states, respectively, by the B3LYP method, but to be the 1 A and 2 B states, respectively, by the MRMP2 method. In 1 , the DFT‐optimized ReRe distance of the 7 B state differs much from the experimental value of similar complex such as [Re 2 IV (μ‐O) 2 (Metpa) 2 ] ( A1 ) and [Re 2 IV (μ‐O) 2 (Me2tpa) 2 ] ( A2 ) (Metpa: ((6‐methyl‐2‐pyridyl)‐methyl)bis(2‐pyridylmethyl)amine, Me2tpa: bis((6‐methyl‐2‐pyridyl)methyl)(2‐pyridylmethyl)amine) that of 1 A state is in good agreement with the experimental one. In 2 , the DFT‐optimized ReRe distance of the 6 B state differs much from the experimental value of the similar complex, [Re 2 IV (μ‐O) 2 (Metpa) 2 ] ( B ), too, but that of the 2 B state agrees well with the experimental value. These results indicate that the ground state of 1 and 2 are the 1 A and 2 B states, respectively, as assigned by the MRMP2 method. Two large absorption bands about 2.1 and 2.6 eV for A1 and A2 are theoretically assigned to be 1 1 B and 2 1 B states by the MRMP2 method. These energies are calculated to be 2.12 and 2.15 eV by the MRMP2 method, which are in good agreement with the experimental values of the similar complexes. Significant difference in absorption spectra of B from those of A1 and A2 are also discussed, based on MRMP2 calculations. © 2009 Wiley Periodicals, Inc. Int J Quantum Chem, 2009
Proposal for broad-range directional detection of light dark matter in cryogenic ice

Field: Physics and Astronomy (Physical Sciences)

We propose hexagonal ice (H2O) as a new target for light dark matter (DM) direct detection. Ice, a polar material, is suitable for single phonon detection through DM scattering for which we consider light dark photon and light scalar mediator models. We report a rate sensitivity down to a DM mass of ∼keV, constituting a broader mass range than other promising candidates. We find better sensitivity for near-term experimental thresholds from the presence of high-frequency phonons. These advantages, and ice’s availability, make it highly promising for single-phonon detection. Published by the American Physical Society 2024
Selective Control of Photo Sharing on Online Social Network

Field: Computer Science (Physical Sciences)

Online social networks provides facilities such as sharing, hosting , uploading and photo management which are shared and transferred online on social network. Photo sharing is an attractive feature which popularizes Online Social Networks (OSNs). Unfortunately, it may leak users’ privacy if they are allowed to post, comment, and tag a photo freely. In this paper, we attempt to address this issue and study the scenario when a user shares a photo containing individuals other than himself/herself (termed co-photo for short). To prevent possible privacy leakage of a photo, we design a mechanism to enable each individual in a photo be aware of the posting activity and participate in the decision making on the photo posting. For this purpose, we need an efficient facial recognition (FR) system that can recognize everyone in the photo. However, more demanding privacy setting may limit the number of the photos publicly available to train the FR system[1]. To deal with this dilemma, our mechanism attempts to utilize users’ private photos to design a personalized FR system specifically trained to differentiate possible photo co-owners without leaking their privacy. We also develop a distributed consensus based method to reduce the computational complexity and protect the private training set. We show that our system is superior to other possible approaches in terms of privacy using encryption algorithm and opensource. Our mechanism is implemented as a proof of concept Android application on Face book’s platform.
Normal Systolic Blood Pressure at Presentation With Acute Ischemic Stroke Predicts Cardioembolic Etiology

Field: Medicine (Health Sciences)

Background Early insight into the possible etiology of ischemic stroke allows for early initiation of mechanism‐specific secondary stroke prevention. Initial systolic blood pressure during acute ischemic stroke may relate to stroke etiology. We sought to determine whether normotension at presentation with acute ischemic stroke predicts cardioembolic etiology. Methods and Results All patients presenting with acute ischemic stroke within 12 hours of symptom onset at a comprehensive stroke center from January 2015 to December 2017 were assessed. Normotension was defined as systolic blood pressure ≤130 mm Hg. The primary exposure was blood pressure on arrival at the hospital, and the primary outcome was cardioembolic etiology. Multivariable regression with stepwise selection was used to adjust for relevant covariates. We included 683 patients in our analysis, 303 (44%) of whom were diagnosed with cardioembolic etiology at 6 months. The probability of cardioembolic etiology was inversely associated with systolic blood pressure , and initial systolic blood pressure was significantly associated with cardioembolic etiology ( odds ratio: 1.15; 95% CI, 1.05 to 1.26). Normotension was associated with 2.62‐fold increased odds of cardioembolic etiology (95% CI, 1.46 to 4.72). Conclusions Normotension at presentation with acute ischemic stroke strongly predicts cardioembolic etiology. These patients may especially benefit from early and prolonged cardiac investigations.

Methyl 4-Hydroxy-2,2-Dioxo-1H-2λ6,1-Benzothiazine-3-Carboxylate and Its Analogs Modified in the Benzene Moiety of the Molecule as New Analgesics

Field: Pharmacology, Toxicology and Pharmaceutics (Life Sciences)

In order to identify new regularities of the “structure–analgesic activity” relationship in the series of 2,1-benzothiazine derivatives, the synthesis of methyl 4-hydroxy-2,2-dioxo-1H-2λ6,1-benzothiazine-3-carboxylate and a group of its analogs substituted in the benzene moiety of the molecule, as well as their mono-and diammonium salts, was performed with tris(hydroxymethyl)aminomethane. The algorithm was proposed; it allows for uniquely solving the question of the nature of the substituent and its true position in the benzothiazine core based on the complex use of NMR (1H and 13C) and mass spectrometry data. Using single-crystal X-ray diffraction analysis it was proven that salt formation first passes through the cyclic sulfamide group and only then through the 4-hydroxyl group, and is always accompanied by a significant conformational rearrangement of the molecule. Based on the results of pharmacological tests it was found that modification of the benzene moiety of the molecule can be used as a method for enhancing the analgesic properties of the class of compounds studied. The presence of a substitute in position 7 is particularly effective, regardless of its nature. A comparative analysis of the analgesic activity of the initial esters and their mono- and diammonium salts convincingly showed that the common belief about a direct relationship between the solubility of a substance and the level of its biological effect is not always true. As it turned out, increasing the solubility in water can lead to a variety of consequences: From a significant increase in analgesia to its complete elimination. It was suggested that the analgesic activity of the compounds studied is determined not by solubility, but by the molecular conformations formed during their obtainment.
SYSTEMIC PETIDOGLYCAN (PEPG) STIMULATES PROINFLAMMATORY RESPONSES IN SYNERGY WITH LIPOPOLYSACCHARIDE (LPS) IN AN IN VIVO AND IN VITRO PORCINE MODEL

Field: Medicine (Health Sciences)

Background: The incidences of mixed and Gram-positive infections are increasing, frequently with resistant bacterial strains. PepG, a cell wall component in Gram-positive bacteria, stimulates inflammation in both in vitro and in vivo studies. Systemic inflammatory effects of PepG or PepG and LPS in combination have never before been tested in a large animal model. Methods: Anesthetised pigs had an 8 hours infusion of LPS (4 microg/kg/h), PepG (40 microg/kg/h), both PepG and LPS, or normal saline. The concentration of TNF-α, IL-1β, IL-6,8 and 10 were measured in vivo before start of the infusions (time 0) and then every 2 hour. From the same animals, heparinised blood was drawn at time 0 and after 6 hours with PepG or LPS infusion, thereafter incubated for 6 hours in a whole blood model with PepG (10 microg/mL), LPS (10 nanog/mL) or both. Concentrations of TNF-α, IL-1β and IL-8 were thereafter measured. Results: In vivo, infusions of LPS, PepG or both, transiently upregulated TNF-α. LPS, but not PepG, increased serum concentrations of IL-6 and 8. In vitro, LPS and PepG had a synergistic effect on the production of TNF-α. In blood drawn after 6 hours infusion with LPS or PepG¸ tolerance and cross-tolerance were detected between the 2 endotoxins as measured by the concentrations of TNF-α, IL-1β and IL-8. Conclusions: Systemic PepG upregulated TNF-α in synergy with LPS. Tolerance and cross-tolerance between LPS and PepG are demonstrated in this porcine model. Thus, PepG alone or in combination with LPS has probably important impacts on the stimulation of inflammatory responses.

SU‐E‐T‐741: The Resources and Cost to Operate An Intraoperative Radiation Therapy Program for Accelerated Partial Breast Irradiation Using a Low‐Energy X‐Ray Source

Field: Health Professions (Health Sciences)

Purpose: To report our experience regarding resource requirements and cost to operate an intraoperative‐radiation therapy (IORT) since 2011, for accelerated‐partial‐breast irradiation (APBI) using the Axxent controller (Xoft Inc.). Methods: To start an IORT program for APBI utilizing the Axxent controller with 50‐keV x‐ray source, the required resources include acquisition of the Axxent controller and a set of quality assurance (QA) tools, the training of involved professionals‐surgeons, oncologists, nurses, and physicists‐to use and operate the system, state license, storage room for the equipment, full‐time availability of the operating personnel on the procedure day, a survey meter, an ultrasound unit, sparing for x‐ray source (at least, two) and cooling‐tubing system, shielding equipment, etc. In each treatment day, QA procedures are required to test the controller performance before patient irradiation in the operation room (OR). Results: During 40 months, 76 procedures were performed. Six surgeons, two oncologists, three nurses and three physicists were trained for the procedure. Irradiation times ranged 7.4–28.6 (mean=11.7) minutes. Eight different x‐ray sources were utilized with usage times ranging 33.4–166.8 (mean=108.7) minutes. Sixteen different combinations of spherical‐balloon applicators and volumes were employed, with 40‐cc (22%) and 30‐cc (20%) volumes of the 3–4‐cm applicator being the most used. Replacement of the x‐ray sources due to arcing during patient irradiation and leak of the cooling‐water system in the OR occurred twice and once, respectively. A defective brand‐new x‐ray source (arcing) happened once. Conclusion: To start and maintain a successful IORT program, for APBI using a low‐energy x‐ray source, institutional commitment‐in addition to the resource requirements that are specific to the program‐is necessary. Based on our over‐3‐year experience, the cost of the x‐ray sources and equipment services along with vendor contract averaged US$1,000–2,000 per treatment, without considering manpower and any other resource expenses.

Red Blood Cell Transfusion in Animal Models of Acute Brain Injuries: A Systematic Review Protocol

Field: Medicine (Health Sciences)

Abstract Background: Anemia is common in neurocritically ill patients. Considering the limited clinical evidence in this population, preclinical data may provide some understanding of the potential impact of anemia and of red blood cell transfusion in these patients. We aim to estimate the association between different transfusion strategies and neurobehavioral outcome in animal models. Methods: We will conduct a systematic review of comparative studies of red blood cell transfusion strategies using animal models of traumatic brain injury, ischemic stroke or cerebral hemorrhage. We will search MEDLINE, EMBASE and Web of Science databases for eligible studies. Two independent reviewers will perform study selection and data extraction. We will report our results in a descriptive synthesis focusing on characteristics of included studies, reported outcomes, risk of bias and construct validity. If appropriate, we will also perform a quantitative synthesis and pool results using random-effect models. Heterogeneity will be expressed with I 2 statistics. Subgroup analyses are planned according to animal model characteristics, co-interventions and risks of bias. Discussion: Our study is aligned with the efforts to better understand the level of evidence on the impact of red blood cell transfusion strategies from preclinical studies in animal models of acute brain injury and the potential translation of information from the preclinical to the clinical research field.

Health and Nutrition Advertising Impacts on the Demand for Orange Juice in Fifty Metropolitan Regions

Field: Economics, Econometrics and Finance (Social Sciences)

Abstract Orange-juice demand is related to generic advertising through a psychological stock variable, which in turn is specified as a function of advertising quality. A double log demand model is used, allowing diminishing returns to advertising, and a solution to the problem of taking the log of zero stock is considered. The empirical analysis examines variation in the impact of orange-juice advertising across regions. Results suggest that health messages of advertising were effective in increasing the demand for orange juice, with the effectiveness varying from region to region. On average, generic advertising was estimated to increase orange-juice demand by about 6.9%.

In this paper we focus on the solution of shifted quasiseparable systems and of more general parameter dependent matrix equations with quasiseparable representations. We propose an efficient algorithm exploiting the invariance of the quasiseparable structure under diagonal shifting and inversion. This algorithm is applied to compute various functions of matrices. Numerical experiments show that this approach is fast and numerically robust.
Kepuasan dan Loyalitas Konsumen Restoran Bakso Bakwan Malang

Field: Business, Management and Accounting (Social Sciences)

Bakso is the popular food in Indonesia and has many kinds of variation. One of them is Bakso Bakwan Malang Cak Su Kumis which has been established for decades by maintaining its unique taste. This study aims to identify the characteristics, analyze the level of satisfaction and the consumer loyalty. In this study, there were 100 respondents included. The methods used in this study are descriptive analysis, Customer Satisfaction Index (CSI), Importance Performance Analysis (IPA) and brand loyalty pyramid analysis. The results of the CSI analysis showed that the value of customer satisfaction has a score of 79,99 which states that consumers are satisfied. Besides that, analysis of the level of consumer loyalty shows that even though consumers are satisfied with the restaurant performance, consumers are not loyal yet. Hence, the performance improvement can be conducted by improving attributes with low performance such as sale promotion, serving time, name board, price and food hygiene.
Possibilities and limitations of utilizing28Mg for studying Mg‐specific problems in higher plants

Field: Agricultural and Biological Sciences (Life Sciences)

Abstract The possibility of utilizing artifical radionuclides in agricultural biological research enabled studies to be implemented in which the detection sensitivity of the nutrients to be investigated was one to two powers of ten higher than with physicochemical methods. Although usable radionuclides are available for numerous plant nutrients, their radiochemical properties partly restrict their utilization. For example, the relatively short half‐life of 28Mg of 21.3 hours only permits short‐term studies. This is all the more disadvantageous the lower the specific activity of 28Mg is. The 28Mg produced from a lithium target in the experimental reactor Merlin at the KFA Jülich achieves a maximum specific activity of 1 mCi/g Mg. In contrast, specific activities of over 1 Ci/g Mg are achieved in the isochronous cyclotron where 28Mg is generated from an aluminium target. This more or less carrier‐free 28Mg is especially suitable for short‐term studies (minutes or hours) or for problem areas in which the 28Mg uptake rates are very low. It was able to be demonstrated on the basis of autoradiographs that Mg is a relatively mobile nutrient in higher plants and is transported both in the xylem and also in the phloem. Its uptake and transport rate does not only depend on the presence and concentration of competing cations but is also considerably influenced by the type of plant and its nutritional status, especially by its K content. In studies on strawberry plants and grapevines it was demonstrated that the transport rate of Mg in the fruits was in part considerably greater than that of Ca. However, this relative preference for Mg in comparison to Ca largely depends in the case of grapevines on the uptake conditions and the type of application (dipping or trough application). In comparative studies of the leaf uptake of 28Mg it was established that considerably more 28Mg was taken up from 28MgCl2 than from a complete nutrient solution or leaf dressing solution.

A photo of a realistic watercolor painting of an up-close house. The house looks almost hidden because of the light cream color used. The pale red roof allows the house to be seen. The house has windows, some of which have dark shadowing that reflects the angle of the sun. The blue sky, green foliage, and pale lime green trees soften the starkness of the house and welcome the visitor that treads on the sidewalk up the four stairs and to the front door. The pale colors of the flowers and trees are gentle and welcoming. The older era house looks like a Southern style house.
The Contingency Value of Complementary Capabilities in Product Development

Field: Business, Management and Accounting (Social Sciences)

Current interdisciplinary research suggests that organizational capabilities have a direct, unconditional impact on firm performance. The authors extend this literature by developing a framework that proposes a contingency approach to the value of organizational capabilities. This framework highlights the effect of information in the external environment in stimulating firms to deploy their technology and marketing capabilities to influence the level and speed of relevant product development activities. Using a longitudinal quasiexperiment to isolate the effects of external information on the relationship between firm capabilities and product development outcomes, the authors obtain results that are consistent with this framework. The authors therefore conclude that the most valuable characteristic of firm capabilities may be their ability to serve as flexible strategic options. In this role, firms can deploy them in ways consistent with environmental forces.
Considering adaptive genetic variation in climate change vulnerability assessment reduces species range loss projections

Field: Biochemistry, Genetics and Molecular Biology (Life Sciences)

Local adaptations can determine the potential of populations to respond to environmental changes, yet adaptive genetic variation is commonly ignored in models forecasting species vulnerability and biogeographical shifts under future climate change. Here we integrate genomic and ecological modeling approaches to identify genetic adaptations associated with climate in two cryptic forest bats. We then incorporate this information directly into forecasts of range changes under future climate change and assessment of population persistence through the spread of climate-adaptive genetic variation (evolutionary rescue potential). Considering climate-adaptive potential reduced range loss projections, suggesting that failure to account for intraspecific variability can result in overestimation of future losses. On the other hand, range overlap between species was projected to increase, indicating that interspecific competition is likely to play an important role in limiting species’ future ranges. We show that although evolutionary rescue is possible, it depends on a population’s adaptive capacity and connectivity. Hence, we stress the importance of incorporating genomic data and landscape connectivity in climate change vulnerability assessments and conservation management.
