Low-Scaling Quantum Chemistry Approach to Excited-State Properties via an ab Initio Exciton Model: Application to Excitation Energy Transfer in a Self-Assembled Nanotube

We introduce a charge-embedding scheme for an excited-state quantum chemistry method aimed at weakly interacting molecular aggregates. The Hamiltonian matrix for the aggregate is constructed in a basis of direct products of configuration-state functions for the monomers, and diagonalization of this matrix affords excitation energies within ∼0.2 eV of the corresponding supersystem calculation. Both the basis states and the coupling matrix elements can be computed in a distributed way, resulting in an algorithm whose time-to-solution is independent of the number of chromophores, and we report calculations on systems with almost 55 000 basis functions using fewer than 450 processors. In a semiconducting organic nanotube, we find evidence of ultrafast, coherent dynamics followed by energy localization driven by static disorder. Truncation of the model system has a qualitative effect on the energy-transfer dynamics, demonstrating the importance of simulating an extended portion of the nanotube, which is not feasible using traditional quantum chemistry.
Major trade indicators of chemical industry in India

In this paper an effort was made to examine the major trade indicators of Chemical industry in India for the reference period spreading between 2000–2014. This study was based on secondary data. Tools of analysis such as base year index number, chain index number, Market shares (MS), Trade Openness Factor, Exports to Imports Ratio were used to analyse the data. It was found that both export and import indices had shown fluctuations throughout the reference period under study i.e from 2000 to 2014. Export share was always lower than the import share except in the year 2001 and 2014. More than 90 percent of changes in the growth of export were due to the influence of time factor and the remaining negligible percentage might be due to other related factors which were incidental. The maximum trade openness was occurred to the extent of 71.22 percent in the year 2008.
Some challenges in developing community noise policy

There are a number of measures of success for environmental noise policy. For the regulatory or enforcement agency the measure of success is the lack of (or the reduction in) complaints about the noise in the area. This is a clearly quantifiable measure. For those responsible for the source of the noise a successful environmental policy is one that has clear and specific criteria for compliance which can be met in a cost effective manner. Again this is a quantifiable assessment. For the community the measure of success is satisfaction with the aural environment. Such satisfaction is a subjective measure. When establishing a noise policy the regulatory agency must match an understanding and knowledge of the community expectations with a quantifiable measure of noise. This measure then becomes the basis for the implementation of amelioration measures for the noise generator as well as the mechanism for the enforcement agency to verify compliance. Measuring the noise levels in the community has become relati...
APPARATUS AND METHODS FOR TREATING THE AORTA

An endovascular stent and an aortic valve replacement can be used to treat the aorta. An endovascular stent suitable for treating the ascending aorta includes a circumferential wall with one or more portions configured to allow blood to flow therethrough, and one or more portions configured to be substantially impermeable. In one version, the blood-permeable portion is defined by bare metal with fenestrations defined therein, and the impermeable portion is formed from polymeric material. The permeable and impermeable portions of the stent are sized, shaped, and located so that, when positioned in the blood vessel to be treated, the impermeable portion is in operative proximity to an aneurysm, dissection, or other area to be treated, and the permeable, bare metal portion is in operative proximity to other blood vessels which need to receive blood from the blood vessel being treated. An aortic valve replacement includes multiple flanges that can be seated in the sinuses of valsalva. The stent or aortic valve replacement may be included in a suitable apparatus for treatment of the aorta. The apparatus for treating the aorta may include a delivery system adapted to be inserted through the apex of the left ventricle of the heart.
Sustainable, wireless, autonomous nanocellulose-based quantitative doa biosensing platform

Paper-based printed electronics are new recyclable electronic devices with technical, economic and environmental advantages. Additionally, nanocellulose (NC) based printed electronics, produced mainly from wood pulp, offer better printability and performance than paper. Therefore, the integration of NC-based printed electronics and biosensors is a promising source of innovation in the biomedical industry. In GREENSENSE we propose the development of a sustainable NC-based biosensing platform for Drug-of-Abuse (DoA) analysis, that integrates high-added value printed electronic components (a new biosensor, an NFC communication system, an energy storage system and a display) with a silicon microchip to provide it with multi sensor data processing, autonomy and wireless communication and that is easy for the user to read.  The main goal of the project will be the use of NC as: substrate for the printed electronics, lamination film for the encapsulation of the final device and as active component in the formulation of functional inks (conductive, electrochemical, electrolyte and dielectric). In all cases the NC surface will be functionalized to be printable, with good barrier properties and compatible with the functional inks (bioactive, conductive, dielectric, electrochemical, electrochromic and electrolyte). Pilot lines and high throughput, high precision and cost-effective S2S screen-printing and ink-jet printing techniques will be used to produce materials and components at large-scale. Two types of DoA biosensing platforms to eradicate the consume of drugs among the society will be developed: a strip-based platform (2nd generation) that will be connected to a Smartphone and a strip+reader-based platform (3rd generation) that will also include a display. The final flexible and recyclable NC-based biosensing platform will be mass producible with ultra-low power consumption and, therefore, cost-effective, sustainable and environmentally friendly.
Biology in a gray box: targeting the emergent properties of protein complexes: 2011 Yale Chemical Biology Symposium.

At the 2011 Yale Chemical Biology Symposium, Jason Gestwicki presented a novel yet intuitive approach to drug screening. This method, which he termed "gray box" screening, targets protein complexes that have been reconstituted in vitro. Therefore, the gray box screen can achieve greater phenotypic complexity than biochemical assays but avoids the need for target identification that follows cell-based assays. Dr. Gestwicki's research group was able to use the gray box screen to identify myricetin as an inhibitor of the DnaK-DnaJ chaperone complex. This review will discuss Dr. Gestwicki's approach to identifying DnaK-DnaJ inhibitors as well as where the gray box screen fits among traditional techniques in drug discovery.

HIGHLY WIND RESISTANT PRE-ASSEMBLED RELOCATABLE BUILDING STRUCTURE WITH CONTINUOUS SHEET OUTER WALL

In order to provide a pre-assembled, relocatable building structure which can be transported by road from one site to another, a metal skeleton (318) which is formed of 6 x 2 inch rectangular cross section hollow steel tubing, is welded together and provided with horizontally extending anchor brackets (324) at the bottom of each vertically extending column member (330). These anchor pads (324) allow the building to be lowered onto foundations in which anchor bolts (104) are imbedded, and bolted in place. The foundations are formed so as to take the form of continuous elongate footers (102) which break the passage of wind which tends to flow sideways under the housing structure. A shallow crawl space (105) can be formed between the foundation footers to facilitate service connections. Metal brackets (301, 302, 303, 304) are used to enclose or encapsulate the edges of the panels in a manner which prevents the direct contact with the wind.
FLOTATION MODULE FOR PRESSURIZED DEINKING

A mixture of air, paper stock made from recycled paper, foaming agents and surfactants are injected into a pressurized container (22). The container has a stock inlet (23) at an end opposite a stock outlet (50), and three outlets (38, 58, 68) arranged along the top of the container between the stock inlet and the stock outlet. The first top outlet nearest the stock inlet is separated from the second and third outlets by a baffle (44), and the second and third outlets are separated from the stock outlet by a baffle (52). Each outlet has a valve (62, 64, 70) which controls flow from that outlet. By adjusting the outlet valves, foam and waste ink is vented from the first and second outlets from the stock inlet, while stock is vented from the third outlet which is closest to the stock outlet. The stock passing through the third outlet is recycled through the container.
Spleen function after preservation in a physiological solution

The purpose of this study was to evaluate the morphology and function of implanted autogenous spleen tissue after 24 h of preservation in a physiological solution.Thirty-five male rats were divided into seven groups (n = 5): group 1, without surgical procedure; group 2, total splenectomy; group 3, total splenectomy and immediate implant of autogenous spleen tissue; group 4, total splenectomy and preservation of the entire spleen in lactated Ringer solution at room temperature for 24 h, followed by spleen sectioning and implantation; group 5, total splenectomy, followed by spleen sectioning and preservation in lactated Ringer solution at room temperature for 24 h and subsequent implantation of the slices; group 6, total splenectomy and preservation of the entire spleen in lactated Ringer solution at 4°C for 24 h, followed by spleen sectioning and implantation; and group 7, total splenectomy, the spleen was sliced and preserved in lactate Ringer solution at 4°C for 24 h, followed by implantation of the slices. After 90 d, scintigraphic studies using sulfur colloid labeled with 99mTc of the liver, lungs, spleen, implants, and a blood clot were performed. Hematological (erythrogram, leukogram, and platelets) and histologic studies were carried out.The autogenous splenic implants regenerated in all animals that received those implants preserved at 4°C and immediately after excision. The scintigraphic study showed a better phagocytic function in groups 1, 3, 6, and 7. No difference was observed in the hematological study.Spleen tissue preserved in lactated Ringer solution at 4°C for 24 h maintains its vitality and capacity to recover hematological and phagocytic functions.
Unattached radon progeny as an experimental tool for dosimetry of nanoaerosols: Proposed method and research strategy

In this paper the authors discuss a method using 1-nm particulate radon decay products as an experimental tool in the study of local lung deposition and dosimetry for nanoaerosols. The study of aerosol exposure and dosimetry measurements, and related quantitative assessment of health effects, are important to the understanding of the consequences of air pollution, and are discussed widely in the scientific literature. During the last 10 years the need to correlate aerosol exposure and biological effects has become especially important due to rapid development of a new, revolutionary industry--nanotechnology. Quantitative assessment of aerosol particle behavior in air, in lung deposition, and dosimetry in different parts of the lung, particularly for nanoaerosols, remains poor despite several decades of study. Direct nanoparticle dose measurements on humans are still needed in order to validate the hollow cast, animal studies, and lung deposition modeling. The issue of the safe use of radon progeny in such measurements is discussed. One of the properties of radon progeny is that they consist partly of 1-nm radioactive particles called unattached activity; having extremely small size and high diffusion coefficients, these particles can be potentially useful as radioactive tracers in the study of nanometer-sized aerosols.
When you smile, the world smiles at you: ERP evidence for self-expression effects on face processing

Current models of emotion simulation propose that intentionally posing a facial expression can change one's subjective feelings, which in turn influences the processing of visual input. However, the underlying neural mechanism whereby one's facial emotion modulates the visual cortical responses to other's facial expressions remains unknown. To understand how one's facial expression affects visual processing, we measured participants' visual evoked potentials (VEPs) during a facial emotion judgment task of positive and neutral faces. To control for the effects of facial muscles on VEPs, we asked participants to smile (adopting an expression of happiness), to purse their lips (incompatible with smiling) or to pose with a neutral face, in separate blocks. Results showed that the smiling expression modulates face-specific visual processing components (N170/vertex positive potential) to watching other facial expressions. Specifically, when making a happy expression, neutral faces are processed similarly to happy faces. When making a neutral expression or pursing the lips, however, responses to neutral and happy face are significantly different. This effect was source localized within multisensory associative areas, angular gyrus, associative visual cortex and somatosensory cortex. We provide novel evidence that one's own emotional expression acts as a top-down influence modulating low-level neural encoding during facial perception.
Impacto en el consumo de TV en España debido a las restricciones de movilidad por covid-19 en 2020

El 14 marzo de 2020 se decretó en España el estado de alarma incluyendo medidas restrictivas de movilidad y de la actividad económica. Estas restricciones provocaron cambios en los hábitos de vida, entretenimiento y consumo de medios. La constante necesidad de información impulsó a la televisión como canal de confianza para acercar la actualidad a la ciudadanía. La interrupción de la programación con avances informativos marcó la parrilla televisiva y disparó su consumo, sobre todo en momentos de confinamiento estricto. Se produjo una caída de la inversión publicitaria en televisión de -18,4% respecto a 2019 y de -50% en los meses de abril y mayo. El incremento del consumo de televisión se puede explicar por dos motivos: la necesidad de información sobre el contexto epidemiológico y el incremento del tiempo que el ciudadano pasó en su residencia como consecuencia de las restricciones de movilidad. El primer punto puede contrastarse con el aumento significativo de la audiencia de los telediarios, el segundo, estudiando la correlación entre consumo y movilidad de los ciudadanos. Este análisis permite predecir el consumo televisivo en función de la movilidad y diseñar mejores estrategias de planificación de medios adaptadas a los posibles escenarios provocados por el covid-19.
Salt Formation of Lactic Acid Oligomers as Matrix for Sustained Release of Drugs

Abstract The calcium and sodium salts of l- and d, l-lactic acid oligomers were obtained by immersion of the oligomer powders (weight average mol. wt 3000–10000) in aqueous solutions of CaCl2 and NaCl, respectively, at room temperature (22°C). The salt formation was analysed by atomic absorption measurement. The thermal properties, including glass transition temperature, melting temperature, and softening temperature, were altered by conversion of the terminal free acid of the oligomer to its salt. An in-vitro release test of an anti-cancer drug from the oligomer beads showed that the drug was released more rapidly from the beads prepared from the non-converted oligomers than those prepared from the salts when the release test was carried out in media containing no calcium and no sodium ions.
On Waringʼs problem for systems of skew-symmetric forms

This paper is devoted to a problem of finding the smallest positive integer s ( m , n , k ) such that ( m + 1 ) generic skew-symmetric ( k + 1 ) -forms in ( n + 1 ) variables as linear combinations of the same s ( m , n , k ) decomposable skew-symmetric ( k + 1 ) -forms. This problem is analogous to a well known problem called Waringʼs problem for symmetric forms and can be very naturally translated into a classical problem in algebraic geometry. In this paper, we will go through some basics of algebraic geometry, describe how objects in algebraic geometry can be associated to systems of skew-symmetric forms, and discuss algebro-geometric approaches to establish the existence of triples ( m , n , k ) , where s ( m , n , k ) is more than expected.
